(the "Guarantor") and the Trustee, dated as of [_____________] (collectively,
the "Indenture"). The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act as in effect on the date of the Indenture. The Securities are
subject to all terms and provisions of the Indenture, and Securityholders are
referred to the Indenture and the Trust Indenture Act for a statement of such
terms and provisions.

                                        9

     The Securities are senior unsecured obligations of the Company initially
limited to $[___________] aggregate principal amount at any one time
outstanding. This Security is one of a Series designated as [____]% Senior Notes
due [____] of the Company.

     Section 2.  REDEMPTION

     All or a portion of the Securities will be redeemable at any time or from
time to time at the option of the Company at a redemption price equal to the
greater of

     (a)  one hundred percent (100%) of the principal amount of the Securities
to be redeemed on the redemption date; and

     (b)  the sum of the present values of the remaining scheduled payments of
principal and interest on the Securities being redeemed on such redemption date
(not including any portion of any payments of interest accrued to the redemption
date), discounted to the redemption date on a semiannual basis at the Treasury
Rate (as defined below), plus 15 basis points,

plus, in each case, accrued and unpaid interest on the Securities to the
redemption date. Notwithstanding the foregoing, installments of interest on the
Securities that are due and payable on interest payment dates falling on or
prior to a redemption date will be payable on the interest payment date to the
registered Securityholders as of the close of business on the relevant record
date according to the Securities and the Indenture. The redemption price will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.

     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Securityholder. Once notice of
redemption is mailed, the Securities called for redemption will become due and
payable on the redemption date and at the applicable redemption price, plus
accrued and unpaid interest to the redemption date.

     "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.

     "Comparable Treasury Issue" means the United States Treasury security
selected by the Reference Treasury Dealer as having a maturity comparable to the
remaining term of the Securities to be redeemed that would be utilized, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such Securities.

     "Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, (ii) if the Trustee obtains fewer than three such Reference Treasury
Dealer Quotations, the average of all such quotations or (iii) if only one
Reference Treasury Dealer Quotation is received, such Quotation.

                                       10
<Page>

     "Reference Treasury Dealer" means (i)[____________________________________
__________________________________________________________________________] (or
its respective affiliates which are Primary Treasury Dealers) and their
respective successors; provided, however, that if any of the foregoing shall
cease to be a primary U.S. Government securities dealer in New York City (a
"Primary Treasury Dealer"), the Company shall substitute therefor another
Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer(s) selected
by the Company.

     "Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. (New York
City time) on the third business day preceding such redemption date.

     On and after the redemption date, interest will cease to accrue on the
Securities or any portion of the Securities called for redemption (unless the
Company defaults in the payment of the redemption price and accrued interest).
On or before the redemption date, the Company will deposit with a Paying Agent
or the Trustee money sufficient to pay the redemption price of and accrued
interest on the Securities to be redeemed on that date. If less than all of the
securities of any series are to be redeemed, the securities to be redeemed shall
be selected by the Trustee by a method the Trustee deems to be fair and
appropriate.

     Section 3.  PAYMENT OF ADDITIONAL AMOUNTS

     The Company shall pay to any Securityholder who is a non-United States
person such additional amounts ("Additional Amounts") as may be necessary in
order that every net payment in respect of the principal, premium, if any, or
interest, if any, on such Securities, after deduction or withholding by the
Company or any Paying Agent for or on account of any present or future tax,
assessment or governmental charge imposed upon or as a result of such payment by
the United States or any political subdivision or taxing authority thereof or
therein, will not be less than the amount provided for in such Securities to be
then due and payable before any such deduction or withholding for or on account
of any such tax, assessment or governmental charge. The foregoing obligation to
pay such Additional Amounts shall not apply to:

     (a)  any tax, assessment or other governmental charge which would not have
been so imposed but for:

          (i)       the existence of any present or former connection between
     such Securityholder (or a fiduciary, settlor, beneficiary, member or
     shareholder of, or holder of a power over, such Securityholder, if such
     Securityholder is an estate, trust, partnership or corporation) and the
     United States, including, without limitation, such Securityholder (or such
     fiduciary, settlor, beneficiary, member, shareholder of, or holder of a
     power) being or having been a citizen or resident or treated as a resident
     thereof or being or having been engaged in a trade or business therein or
     being or having been present therein or having or having had a permanent
     establishment therein, or

                                       11
<Page>

          (ii)      such Securityholder's present or former status as a personal
     holding company or foreign personal holding company or controlled foreign
     corporation for United States federal income tax purposes or corporation
     which accumulates earnings to avoid United States federal income tax;

     (b)  any tax, assessment or other governmental charge which would not have
been so imposed but for the presentation by the Securityholder for payment on a
date more than 10 days after the date on which such payment became due and
payable or the date on which payment thereof is duly provided for, whichever
occurs later;

     (c)  any estate, inheritance, gift, sales, transfer, personal property or
excise tax or any similar tax, assessment or governmental charge;

     (d)  any tax, assessment or other governmental charge which is payable
otherwise than by withholding from payments in respect of principal of or
interest, if any, on any of the Securities;

     (e)  any tax, assessment or other governmental charge imposed on interest
received by a Securityholder or beneficial owner of the Securities who actually
or constructively owns 10% or more of the total combined voting power of all
classes of stock of the Company entitled to vote within the meaning of Section
871(h)(3) of the United States Internal Revenue Code of 1986, as amended;

     (f)  any tax, assessment or other governmental charge imposed as a result
of the failure to comply with:

          (i)       certification, information, documentation, reporting or
     other similar requirements concerning the nationality, residence, identity
     or connection with the United States of the Securityholder or beneficial
     owner of the Securities, if such compliance is required by statute, or by
     regulation of the United States Treasury Department, as a precondition to
     relief or exemption from such tax, assessment or other governmental charge
     (including backup withholding), or

          (ii)      any other certification, information, documentation,
     reporting or other similar requirements under United States income tax laws
     or regulations that would establish entitlement to otherwise applicable
     relief or exemption from such tax, assessment or other governmental charge;

     (g)  any tax, assessment or other governmental charge required to be
withheld by any Paying Agent from any payment of the principal of or interest,
if any, on any of the Securities, if such payment can be made without such
withholding by at least one other Paying Agent;

     (h)  any tax, assessment or other governmental charge that is required to
be made pursuant to any European Union directive on the taxation of savings
income or any law implementing or complying with, or introduced to conform to,
any such directive; or

     (i)  any combination of items (a), (b), (c), (d), (e), (f), (g) or (h);

                                       12
<Page>

nor will such Additional Amounts be paid to any Securityholder who is a
fiduciary or partnership or other than the sole beneficial owner of the
Securities to the extent a settlor or beneficiary with respect to such fiduciary
or a member of such partnership or a beneficial owner of the Securities would
not have been entitled to payment of such Additional Amounts had such
beneficiary, settlor, member or beneficial owner been the Securityholder. The
Securities are subject in all cases to any tax, fiscal or other law or
regulation or administrative or judicial interpretation applicable thereto.
Except as specifically provided under this Section 3, the Company shall not be
required to make any payment with respect to any tax, assessment or governmental
charge imposed by any government or a political subdivision or taxing authority
thereof or therein.

     Section 4.  REDEMPTION FOR TAX REASONS

     If, as a result of:

          (a)  any change in or amendment to the laws (including any regulations
     or rulings promulgated thereunder) of the United States or any political
     subdivision thereof or therein affecting taxation, which becomes effective
     after [_______________] or which proposal is made after such date,

          (b)  any change in the official application or interpretation of such
     laws, including any official proposal for such a change, amendment or
     change in the application or interpretation of such laws, which change,
     amendment, application or interpretation is announced or becomes effective
     after [_______________] or which proposal is made after such date,

          (c)  any action taken by any taxing authority of the United States
     which action is taken or becomes generally known after [_______________],
     or any commencement of a proceeding in a court of competent jurisdiction in
     the United States after such date, whether or not such action was taken or
     such proceeding was brought with respect to the Company,

there is, in such case, in the written opinion of independent legal counsel of
recognized standing to the Company, a material increase in the probability that
the Company has or may become obligated to pay Additional Amounts, and the
Company in its business judgment, determines that such obligation cannot be
avoided by the use of reasonable measures available to it, not including
assignment of the Securities, the Securities affected thereby may be redeemed,
as a whole but not in part, at the Company's option at any time thereafter, upon
notice to the Trustee and the Securityholders affected thereby in accordance
with the provisions of this Security and the Indenture at a redemption price
equal to 100% of the principal amount of the Securities to be redeemed together
with accrued interest thereon to the date fixed for redemption.

     Section 5.  SINKING FUND

     The Securities are not subject to any sinking fund.

     Section 6.  DENOMINATIONS; TRANSFER; EXCHANGE

                                       13
<Page>

     The Securities are in registered form without coupons in denominations of
$1,000 and whole multiples of $1,000. A Securityholder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Trustee may require a Securityholder, among other things, to
furnish appropriate endorsements or transfer documents and to pay any taxes
required by law or permitted by the Indenture. The Registrar need not register
the transfer of or exchange any Securities selected for redemption or to
transfer or exchange any Securities for a period of 15 days prior to the mailing
of a notice of redemption of Securities to be redeemed.

     A global Security deposited with the Depositary or the Trustee shall be
transferred to the beneficial owner thereof in the form of Definitive Securities
only if (a) the Company notifies the Trustee in writing that the Depositary,
Euroclear or Clearstream is no longer willing or able to act as a depositary or
clearing system for the Securities or the Depositary ceases to be registered as
a clearing agency under the Exchange Act, and a successor depositary or clearing
system is not appointed within 90 days of this notice or cessation, (b) the
Company, at its option, notifies the Trustee in writing that it elects to cause
the issuance of the Securities in definitive form under the Indenture or (c)
upon the occurrence and continuation of an Event of Default under the Indenture
with respect to the Securities. Upon surrender by the Depositary of the global
Securities, certificated Securities will be issued to each Person that the
Depositary identifies as the beneficial owner of the Securities represented by
the global Security. Upon any such issuance, the Trustee is required to register
the certificated Securities in the name of the Person or Persons or the nominee
of any of these Persons and cause the same to be delivered to these Persons.
Neither the Company nor the Trustee shall be liable for any delay by the
Depositary or any participant or indirect participant in identifying the
beneficial owners of the related Securities and each such Person may
conclusively rely on, and shall be protected in relying on, instructions from
the Depositary for all purposes, including with respect to the registration and
delivery, and respective principal amounts, of the Securities to be issued.

     Section 7.  EVENTS OF DEFAULT

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

     Section 8.  GUARANTIES.

     The payment of principal of premium and interest on the Securities are
unconditionally guaranteed, jointly and severally, on a senior unsecured basis
by the Guarantor.

     Section 9.  PERSONS DEEMED OWNERS

     The registered Securityholder may be treated as the owner of it for all
purposes.

     Section 10. UNCLAIMED MONEY

     If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to the Company at
its written request unless

                                       14
<Page>

an abandoned property law designates another Person.
After any such payment, Securityholders entitled to the money must look only to
the Company and not to the Trustee for payment.

     Section 11. DISCHARGE AND DEFEASANCE

     Subject to certain conditions, the Company at any time may terminate some
of or all its obligations under the Securities and the Indenture if the Company
deposits with the Trustee money or U.S. Government Obligations for the payment
of principal and interest on the Securities to redemption or maturity, as the
case may be.

     Section 12. TRUSTEE DEALINGS WITH THE COMPANY

     Subject to certain limitations imposed by the Trust Indenture Act, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

     Section 13. NO RECOURSE AGAINST OTHERS

     A director, officer, employee or stockholder, as such, of the Company or
the Guarantor, as such, shall not have any liability for any obligations of the
Company or the Guarantor under the Securities, the Indenture or the Guaranty for
any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Securities.

     Section 14. AUTHENTICATION

     This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

     Section 15. NOTICES

     Notices to Securityholders will be published in authorized daily newspapers
in the City of New York, in London, and, so long as the Securities are listed on
the Luxembourg Stock Exchange, in Luxembourg. It is expected that publication
will be made in the City of New York in THE WALL STREET JOURNAL, in London in
the FINANCIAL TIMES, and in Luxembourg in the LUXEMBURGER WORT. Any notice given
pursuant to these provisions shall be deemed to have been given on the date of
publication or, if published more than once, on the date first published.

<Page>

EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY.

     Section 17. CUSIP NUMBERS

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

     Section 18. DEFINED TERMS

     All terms used in this Security which are defined in the Indenture and not
otherwise defined herein shall have the meanings assigned to them in the
Indenture.

     The Company will furnish to any Securityholder upon written request and
without charge to the Securityholder a copy of the Indenture which has in it the
text of this Security.

     the case may be;

          (14)   whether Securities of the Series are issuable in Tranches;

          (15)   whether, and under what circumstances, the Securities of any
     Series shall be convertible into Securities of any other Series;

          (16)   if other than the Trustee, any trustees, authenticating or
     paying agents, transfer agents or registrars or any other agents with
     respect to the Securities of such Series;

                                       19
<Page>

          (17)   if the Securities of such Series do not bear interest, the
     applicable dates for purposes of Section 4.1 hereof;

          (18)   any deletions from, modifications of or additions to the
     Events of Default or covenants of the Company with respect to Securities of
     the Series, whether or not such Events of Default or covenants are
     consistent with the Events of Default or covenants set forth herein;

          (19)   whether, under what circumstances and the Currency in which,
     the Company will pay Additional Amounts as contemplated by Section 3.5 on
     the Securities of the Series to any Holder who is a non-United States
     Person (including any modification to the definition of such term) in
     respect of any tax, assessment or governmental charge and, if so, whether
     the Company will have the option to redeem such Securities rather than pay
     such Additional Amounts (and the terms of any such option);

          (20)   whether and under what circumstances the Guarantor or any
     other Subsidiary of the Company shall guarantee the Securities and any
     modifications or additions to the Guaranty set forth in Article Thirteen;
     and

          (21)   any other terms or conditions upon which the Securities of the
     Series are to be issued (which terms shall not be inconsistent with the
     provisions of this Indenture).

     All Securities of any one Series shall be substantially identical except as
to denomination, except as provided in the immediately succeeding paragraph, and
except as may otherwise be provided in or pursuant to such resolution of the
Board of Directors or in any such indenture supplemental hereto. All Securities
of any one Series need not be issued at the same time, and unless otherwise
provided, a Series may be reopened, without the consent of the Holders, for
issuances of additional Securities of such Series or to establish additional
terms of such Series of Securities (which additional terms shall only be
applicable to unissued or additional Securities of such Series).

     Each Series may be issued in one or more Tranches. Except as provided in
the foregoing paragraph, all Securities of a Tranche shall have the same issue
date, maturity date, interest rate or method of determining interest, and, in
the case of Original Issue Discount Securities, the same issue price.

     SECTION 2.6    AUTHENTICATION AND DELIVERY OF SECURITIES. At any time and
from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any Series having attached thereto appropriate
Coupons, if any, executed by the Company to the Trustee for authentication, and
the Trustee shall thereupon authenticate and deliver such Securities to or upon
the written order of the Company, signed by both (a) the chairman of its Board
of Directors, or any vice chairman of its Board of Directors, or its president
or any vice president and (b) by its treasurer or any assistant treasurer,
secretary or any assistant secretary without any further action by the Company.
In authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive and (subject to Section 6.1) shall be fully protected in
relying upon:

                                       20
<Page>

          (a)  a certified copy of any resolution or resolutions of the Board of
Directors authorizing the action taken pursuant to the resolution or resolutions
delivered under clause (2) below;

          (b)  a copy of any resolution or resolutions of the Board of Directors
relating to such Series, in each case certified by the secretary or an assistant
secretary of the Company;

          (c)  an executed supplemental indenture, if any;

          (d)  an Officers' Certificate setting forth the form and terms of the
Securities of such Series as required pursuant to Sections 2.1 and 2.3,
respectively, and prepared in accordance with Section 11.5; and

          (e)  an Opinion of Counsel, prepared in accordance with Section 11.5,
which shall state:

               (i)       that the form or forms and terms of such Securities and
     Coupons, if any have been established by or pursuant to a resolution of the
     Board of Directors or by a supplemental indenture as permitted by Sections
     2.1 and 2.3 in conformity with the provisions of this Indenture;

               (ii)      that such Securities and Coupons, if any have been duly
     authorized, and, when authenticated and delivered by the Trustee and issued
     by the Company in the manner and subject to any conditions specified in
     such Opinion of Counsel, will constitute valid and binding obligations of
     the Company enforceable in accordance with their terms, subject to
     applicable bankruptcy, insolvency, reorganization or other laws relating to
     or affecting the enforcement of creditors' rights and by general equitable
     principles, regardless of whether such enforceability is considered in a
     proceeding in equity or at law;

               (iii)     that all laws and requirements in respect of the
     execution and delivery by the Company of the Securities and Coupons, if
     any, and the related supplemental indenture, if any, have been complied
     with;

               (iv)      the registration statement, if any, relating to the
     Securities of such series and any amendments thereto has become effective
     under the Securities Act of 1933 and to the best knowledge of such counsel,
     no stop order suspending the effectiveness of such registration statement,
     as amended, has been issued and no proceedings for that purpose have been
     instituted or threatened;

               (v)       no consent, approval, authorization or order of any
     court or governmental agency or body in the United States is required for
     the issuance of the Securities of such Series, except such as have been
     obtained and such as may be required under the blue sky laws of any
     jurisdiction in the United States in connection with the purchase and
     distribution of the Securities of such Series;

               (vi)      neither the issue nor sale of the Securities of such
     Series will contravene the charter or by-laws of the Company or will
     conflict with, result in a breach

                                       21
<Page>

     of or constitute a default under the terms of any indenture or other
     agreement or instrument known to such counsel and to which the Company or
     any of its Subsidiaries is a party or is bound, or any order or regulation
     known to such counsel to be applicable to the Company or any of its
     Subsidiaries of any court, regulatory body, administrative agency or
     governmental body having jurisdiction over the Company or any of its
     Subsidiaries; and

               (vii)     the authentication and delivery of the Securities of
     such series by the Trustee in accordance with the directions of the Company
     so to do, and the Company's execution and delivery of the Securities of
     such series, will not violate the terms of this Indenture;

PROVIDED, HOWEVER, that in the case of any Series issuable in Tranches, if the
Trustee has previously received the documents referred to in Section 2.6(1)-(5)
with respect to such Series, the Trustee shall authenticate and deliver
Securities of such Series executed and delivered by the Company for original
issuance upon receipt by the Trustee of the applicable Company Notice.

     The Trustee shall have the right to decline to authenticate and deliver any
Securities and Coupons, if any, under this Section if the Trustee, being advised
by counsel, determines that such action may not lawfully be taken by the Company
or if the issue of such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties or immunities under this Indenture in a manner not
reasonably acceptable to the Trustee.

     Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 2.12, together with a written statement (which need not
comply with Section 11.5 and need not be accompanied by an Opinion of Counsel)
stating that such Security has never been issued and sold by the Company, for
all purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

     SECTION 2.7    EXECUTION OF SECURITIES. The Securities shall be signed on
behalf of the Company by both (a) its chairman or its president or any vice
president and (b) its treasurer or any assistant treasurer or its secretary or
any assistant secretary, which may, but need not, be attested. Such signatures
may be the manual or facsimile signatures of the present or any future such
officers. The seal of the Company may be in the form of a facsimile thereof and
may be impressed, affixed, imprinted or otherwise reproduced on the Securities.
Typographical and other minor errors or defects in any such reproduction of the
seal or any such signature shall not affect the validity or enforceability of
any Security that has been duly authenticated and delivered by the Trustee. Any
Coupons attached to any Unregistered Security shall be executed on behalf of the
Company by the manual or facsimile signature of any such officer of the Company.

     In case any officer of the Company who shall have signed any of the
Securities or Coupons shall cease to be such officer before the Security or
Coupon so signed shall be authenticated (in the case of the Securities) and
delivered by the Trustee or disposed of by the Company, such Security or Coupon
nevertheless may be authenticated and delivered or disposed

                                       22
<Page>

of as though the person who signed such Security or Coupon had not ceased to be
such officer of the Company; and any Security or Coupon may be signed on behalf
of the Company by such persons as, at the actual date of the execution of such
Security or Coupon, shall be the proper officers of the Company, although at the
date of the execution and delivery of this Indenture any such person was not
such an officer.

     SECTION 2.8    CERTIFICATE OF AUTHENTICATION. Only such Securities as shall
bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized signatories, shall be entitled to the benefits of this Indenture
or be valid or obligatory for any purpose. Such certificate by the Trustee upon
any Security executed by the Company shall be conclusive evidence that the
Security so authenticated has been duly authenticated and delivered hereunder
and that the Holder is entitled to the benefits of this Indenture.

     The Trustee shall not authenticate or deliver any Unregistered Security
until any matured Coupons appertaining thereto have been detached and canceled,
except as otherwise provided or permitted by this Indenture.

     SECTION 2.9    DENOMINATION AND DATE OF SECURITIES; PAYMENTS OF INTEREST.
The Securities shall be issuable in denominations as shall be specified as
contemplated by Section 2.5. In the absence of any such specification with
respect to the Securities of any Series, the Securities of such Series shall be
issuable in denominations of $1,000 and any multiple thereof, which may be in
Dollars or any Foreign Currency, and interest shall be computed on the basis of
a 360-day year of twelve 30-day months. The Securities shall be numbered,
lettered, or otherwise distinguished in such manner or in accordance with such
plan as the officers of the Company executing the same may determine with the
approval of the Trustee as evidenced by the execution and authentication
thereof.

     Each Security shall be dated the date of its authentication, shall bear
interest from the date and shall be payable on the dates, in each case, which
shall be specified as contemplated by Section 2.5.

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on any interest payment date shall be paid, in the case of
Registered Securities, to the person in whose name that Security (or one or more
predecessor Securities) is registered at the close of business on the regular
record date for the payment of such interest and, in the case of Unregistered
Securities, upon surrender of the Coupon appertaining thereto in respect of the
interest due on such interest payment date.

     The term "record date" as used with respect to any interest payment date
(except for a date for payment of defaulted interest) shall mean the date
specified as such in the terms of the Securities of any particular Series, or,
if no such date is so specified, if such interest payment date is the first day
of a calendar month, the close of business on the fifteenth day of the next
preceding calendar month or, if such interest payment date is the fifteenth day
of a calendar month, the close of business on the first day of such calendar
month, whether or not such record date is a Business Day.

                                       23
<Page>

     Any interest on any Security of any Series which is payable, but is not
punctually paid or duly provided for, on any interest payment date (called
"defaulted interest" for the purpose of this Section) shall forthwith cease to
be payable to the Registered Holder on the relevant record date by virtue of his
having been such Holder; and such defaulted interest may be paid by the Company,
at its election in each case, as provided in clause (1) or clause (2) below:

          (1)       The Company may elect to make payment of any defaulted
     interest to the persons in whose names any such Registered Securities (or
     their respective predecessor Securities) are registered at the close of
     business on a special record date for the payment of such defaulted
     interest, which shall be fixed in the following manner. The Company shall
     notify the Trustee in writing of the amount of defaulted interest proposed
     to be paid on each Security of such Series and the date of the proposed
     payment, and at the same time the Company shall deposit with the Trustee an
     amount of money equal to the aggregate amount proposed to be paid in
     respect of such defaulted interest or shall make arrangements satisfactory
     to the Trustee for such deposit prior to the date of the proposed payment,
     such money when deposited to be held in trust for the benefit of the
     persons entitled to such defaulted interest as in this clause provided.
     Thereupon the Trustee shall fix a special record date for the payment of
     such defaulted interest in respect of Registered Securities of such Series
     which shall be not more than 15 nor less than 10 days prior to the date of
     the proposed payment and not less than 10 days after the receipt by the
     Trustee of the notice of the proposed payment. The Trustee shall promptly
     notify the Company of such special record date and, in the name and at the
     expense of the Company, shall cause notice of the proposed payment of such
     defaulted interest and the special record date thereof to be mailed, first
     class postage prepaid, to each Registered Holder at his address as it
     appears in the Security register, not less than 10 days prior to such
     special record date. Notice of the proposed payment of such defaulted
     interest and the special record date therefor having been mailed as
     aforesaid, such defaulted interest in respect of Registered Securities of
     such Series shall be paid to the person in whose names such Securities (or
     their respective predecessor Securities) are registered on such special
     record date and such defaulted interest shall no longer be payable pursuant
     to the following clause (2).

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

     Any defaulted interest payable in respect of any Security of any Series
which is not a Registered Security shall be payable pursuant to such procedures
as may be satisfactory to the Trustee in such manner that there is no
discrimination as between the Holders of Registered Securities and other
Securities of the same Series, and notice of the payment date therefor shall be
given by the Trustee, in the name and at the expense of the Company, by
publication at least once in a newspaper of general circulation in New York, New
York and London, England.

                                       24

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

     SECTION 2.10   REGISTRATION, TRANSFER AND EXCHANGE. The Company will keep
at the office or agency of the Trustee to be maintained for the purpose as
provided in Section 3.2 a register or registers in which, subject to such
reasonable regulations as it may prescribe, it will register, and will register
the transfer of, Registered Securities as in this Article Two provided. Such
register shall be in written form in the English language or in any other form
capable of being converted into such form within a reasonable time. At all
reasonable times such register or registers shall be open for inspection by the
Trustee.

     Upon due presentation for registration of transfer of any Registered
Security of any Series at any such office or agency to be maintained for the
purpose as provided in Section 3.2, the Company shall execute and the Trustee
shall authenticate and deliver in the name of the transferee or transferees a
new Registered Security or Registered Securities of the same Series in
authorized denominations for a like aggregate principal amount.

     At the option of the Holder thereof, Unregistered Securities of a Series,
which by their terms are registerable as to principal and interest, may, to the
extent and under the circumstances specified pursuant to Section 2.5, be
exchanged for Registered Securities of such Series, as may be issued by the
terms thereof. At the option of the Holder thereof, Registered Securities of a
Series, which by their terms provide for the issuance of Unregistered
Securities, may, to the extent and under the circumstances specified pursuant to
Section 2.5, be exchanged for Unregistered Securities of such Series. Securities
so issued in exchange for other Securities shall be of any authorized
denomination and of like principal amount and maturity date, interest rate or
method of determining interest, and shall be issued upon surrender of the
Securities for which they are to be exchanged and, in the case of Coupon
Securities, together with all unmatured Coupons and matured Coupons in default
appertaining thereto, at the office of the Company provided for in Section 3.2
and upon payment, if the Company shall require, of charges provided therein.
Unregistered Securities of any Series issued in exchange for Registered
Securities of such Series between the regular record date for such Registered
Security and the next interest payment date will be issued without the Coupon
relating to such interest payment date, and Unregistered Securities surrendered
in exchange for Registered Securities between such dates shall be surrendered
without the Coupon relating to such interest payment date. Whenever any
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. Notwithstanding the foregoing, an
Unregistered Security will not be delivered in exchange for a Registered
Security or Securities unless the Trustee receives a certificate signed by the
person entitled to delivery of such Security or other items or documents
fulfilling such conditions as shall be required by regulations of the United
States Department of the Treasury, or shall be notified by the Company that such
a certificate shall not be required by such regulations; provided, however, that
no such Unregistered Security shall be delivered by the Trustee if the Trustee
or such agent shall have, or shall have been notified in writing by the Company
that the Company has, actual knowledge that such certificate is false.

                                       25
<Page>

     Upon presentation for registration of any Unregistered Securities of any
Series which by its terms is registerable as to principal, at the office or
agency of the Company to be maintained as provided in Section 3.2, such Security
shall be registered as to principal in the name of the Holder thereof and such
registration shall be noted on such Security. Any Security so registered shall
be transferable on the registry books of the Company upon presentation of such
Security at such office or agency for similar notation thereon, but such
Security may be discharged from registration by being in a like manner
transferred to bearer, whereupon transferability by delivery shall be restored.
Except as otherwise provided pursuant to Section 2.5 hereof, Unregistered
Securities shall continue to be subject to successive registrations and
discharges from registration at the option of the Holders thereof.

     Unregistered Securities shall be transferable by delivery, except while
registered as to principal. Registration of any Coupon Security shall not effect
the transferability by delivery of the Coupons appertaining thereto which shall
continue to be payable to bearer and transferable by delivery.

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

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

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities, other than exchanges pursuant to
Sections 2.11, 8.5 or 12.3 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange any Security during a period beginning at the opening of business 15
days before the day of mailing of a notice of redemption of Securities for
redemption under Article Twelve or (ii) to register the transfer of or exchange
any Security so selected for redemption in whole or in part, except, in the case
of any Security to be redeemed in part, the portion thereof not redeemed.

     SECTION 2.11   MUTILATED, DEFACED, DESTROYED, LOST AND STOLEN SECURITIES.
In case any temporary or definitive Security or Coupon shall become mutilated,
defaced or be destroyed, lost or stolen, the Company in its discretion may
execute, and upon the written request of any officer of the Company, the Trustee
shall authenticate and deliver, a new Security of the same Series or Coupon,
bearing a number not contemporaneously outstanding, in exchange and substitution
for the mutilated or defaced Security or Coupon, or in lieu of and substitution
for the Security or Coupon so destroyed, lost or stolen. In every case the
applicant for a substitute Security or Coupon shall furnish to the Company and
to the Trustee and to any agent of the Company or the Trustee such security or
indemnity as may be required by them to indemnify and defend and to save each of
them harmless and, in every case of destruction, loss or theft, evidence to
their

                                       26
<Page>

satisfaction of the destruction, loss or theft of such Security or Coupon and of
the ownership thereof.

     Upon the issuance of any substitute Security or Coupon, 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. In case any Security
or Coupon which has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Company may, instead of issuing a substitute Security or Coupon, pay
or authorize the payment of the same (without surrender thereof except in the
case of a mutilated or defaced Security or Coupon); provided, however, that
interest represented by Coupons shall be payable only upon presentation and
surrender of such Coupons at an office or agency of the Company located outside
of the United States, unless otherwise provided pursuant to Section 2.5, if the
applicant for such payment shall furnish to the Company and to the Trustee and
any agent of the Company or the Trustee such security or indemnity as any of
them may require to save each of them harmless, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company and
the Trustee and any agent of the Company or the Trustee evidence to their
satisfaction of the destruction, loss or theft of such Security or Coupon and of
the ownership thereof.

     Every substitute Security of any Series or Coupon issued pursuant to the
provisions of this Section by virtue of the fact that any such Security or
Coupon is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company or Guarantor, if any, whether or not the destroyed,
lost or stolen Security or Coupon shall be at any time enforceable by anyone and
shall be entitled to all the benefits of (but shall be subject to all the
limitations of rights set forth in) this Indenture equally and proportionately
with any and all other Securities of such Series or Coupons duly authenticated
and delivered hereunder. All Securities or Coupons shall be held and owned upon
the express condition that, to the extent permitted by the law, the foregoing
provisions are exclusive with respect to the replacement or payment of
mutilated, defaced, destroyed, lost or stolen Securities or Coupons and shall
preclude any and all other rights or remedies notwithstanding any law or statute
existing or hereafter enacted to the contrary with respect to the replacement or
payment of negotiable instruments or other securities without their surrender.

     SECTION 2.12   CANCELLATION OF SECURITIES. All Securities surrendered for
payment, redemption, registration of transfer or exchange, or for credit against
any payment in respect of a sinking or analogous fund and all Coupons
surrendered for payment or exchange, shall, if surrendered to the Company or any
agent of the Company or the Trustee, be delivered to the Trustee for
cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no
Securities or Coupons shall be issued in lieu thereof, except as expressly
permitted by any of the provisions of this Indenture. The Trustee shall dispose
cancelled Securities in accordance with its customary procedures. If the Company
shall acquire any of the Securities and Coupons, such acquisition shall not
operate as a redemption or satisfaction of the indebtedness represented by such
Securities and Coupons unless and until the same are delivered to the Trustee
for cancellation.

                                       27
<Page>

     SECTION 2.13   TEMPORARY SECURITIES. Pending the preparation of definitive
Securities for any Series, the Company may execute and the Trustee shall
authenticate and deliver temporary Securities for such Series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any Series may be issued
as Registered Securities or Unregistered Securities with or without Coupons
attached thereto, of any authorized denomination, and substantially in the form
of the definitive Securities of such Series but with such omissions, insertions
and variations as may be appropriate for temporary Securities, all as may be
determined by the Company with the concurrence of the Trustee. Temporary
Securities may contain such reference to any provisions of this Indenture as may
be appropriate. Every temporary Security shall be executed by the Company and be
authenticated by the Trustee upon the same conditions and in substantially the
same manner, and with like effect, as the definitive Securities. Without
unreasonable delay the Company shall execute and shall furnish definitive
Securities of such Series and thereupon temporary Securities of such Series may
be surrendered in exchange therefor without charge at each office or agency to
be maintained by the Company for that purpose pursuant to Section 3.2, and the
Trustee shall authenticate and deliver in exchange for such temporary Securities
of such Series a like aggregate principal amount of definitive Securities of the
same Series of authorized denominations and, in the case of Unregistered
Securities, having attached thereto any appropriate Coupons. Until so exchanged,
the temporary Securities of any Series shall be entitled to the same benefits
under this Indenture as definitive Securities of such Series.

     SECTION 2.14   CURRENCY AND MANNER OF PAYMENTS IN RESPECT OF SECURITIES.

          (a)  With respect to Registered Securities of any Series with respect
to which the Holders of such Securities have not made the election provided for
in paragraph (b) below, the following payment provisions shall apply:

               (i)       Except as provided in subparagraph (a)(2) or in
     paragraph (e) below, payment of the principal of any Registered Security
     will be made at the Place of Payment by delivery of a check in the Currency
     in which the Security is denominated on the payment date against surrender
     of such Registered Security, and any interest on any Registered Security
     will be paid at the Place of Payment by mailing a check in the Currency in
     which the Securities were issued to the Person entitled thereto at the
     address of such Person appearing on the Security register.

               (ii)      Payment of the principal of and interest on such
     Security may also, subject to applicable laws and regulations, be made at
     such other place or places as may be designated by the Company by any
     appropriate method.

          (b)  With respect to Registered Securities of any Series, the
following payment provisions shall apply, except as otherwise provided in
paragraphs (e) and (f) below:

               (i)       The Board of Directors may provide with respect to any
     Series of such Securities that Holders shall have the option to receive
     payments of principal of and interest on such Security in any of the
     Currencies which may be designated for such election in such Security by
     delivering to the Trustee a written election, to be in form and substance
     satisfactory to the Trustee, not later than the close of business on the
     record

                                       28
<Page>

     date immediately preceding the applicable payment date. Such election will
     remain in effect for such Holder until changed by the Holder by written
     notice to the Trustee (but any such change must be made not later than the
     close of business on the record date immediately preceding the next payment
     date to be effective for the payment to be made on such payment date and no
     such change may be made with respect to payments to be made on any Security
     with respect to which notice of redemption has been given by the Company
     pursuant to Article Twelve). Any Holder of any such Security who shall not
     have delivered any such election to the Trustee not later than the close of
     business on the applicable record date will be paid the amount due on the
     applicable payment date in the relevant Currency as provided in paragraph
     (a) of this Section 2.14. Payment of principal shall be made on the payment
     date against surrender of such Securities. Payment of principal and
     interest shall be made at the Place of Payment by mailing a check in the
     applicable currency to the Person entitled thereto at the address of such
     Person appearing on the Security register.

               (ii)      Payment of the principal of and interest on such
     Security may also, subject to applicable laws and regulations, be made at
     such other place or places as may be designated by the Company by any
     appropriate method.

          (c)  Payment of the principal of any Unregistered Security and of
interest on any Coupon Security will be made at such place or places outside the
United States as may be designated by the Company by any appropriate method only
in the Currency in which the Security is payable (except as provided in
paragraph (e) below) on the payment date against surrender of the Unregistered
Security, in the case of payment of principal, or the relevant Coupon, in the
case of payment of interest. Except as provided in paragraph (e) below, payment
with respect to Unregistered Securities and Coupons will be made by check,
subject to any limitations on the methods of effecting such payment as shall be
specified in the terms of the Security established as provided in Section 2.5
and as shall be required under applicable laws and regulations. Payment of the
principal of and interest on Unregistered Securities may also, subject to
applicable laws and regulations, be made at such other place or places as may be
designated by the Company by any appropriate method.

          (d)  Not later than the fourth Business Day after the record date for
each payment date, the Trustee will deliver to the Company a written notice
specifying, in the Currency in which each Series of the Securities are
denominated, the respective aggregate amounts of principal of and interest on
the Securities to be made on such payment date, specifying the amounts so
payable in respect of the Registered and the Unregistered Securities and in
respect of the Registered Securities as to which the Holders shall have elected
to be paid in another Currency as provided in paragraph (b) above. If the Board
of Directors has provided for the election referred to in paragraph (b) above
and if at least one Holder has made such election, then not later than the
second Business Day preceding such record date the Company will deliver to the
Trustee an Exchange Rate Officer's Certificate in respect of the Dollar or
Foreign Currency payments to be made on such payment date. The Dollar or Foreign
Currency amount receivable by Holders of Registered Securities who have elected
payment in another Currency as provided in paragraph (b) above shall be
determined by the Company on the basis of the applicable Market Exchange Rate in
effect on the second Business Day (the "Valuation

                                       29
<Page>

Date") prior to such payment date and set forth in the applicable Exchange Rate
Officer's Certificate.

          (e)  If a Conversion Event occurs with respect to a Foreign Currency
in which any of the Securities are denominated or payable, then with respect to
each date for the payment of principal of, premium, if any, and interest on the
applicable Foreign Currency denominated Securities occurring after the last date
on which the Foreign Currency was so used (the "Conversion Date"), the Dollar
shall be the currency of payment for use on each such payment date. The Dollar
amount to be paid by the Company to the Trustee and by the Trustee or any Paying
Agent to the Holders of such Securities with respect to such payment date shall
be, in the case of a Foreign Currency other than a currency unit, the Dollar
Equivalent of the Foreign Currency or, in the case of a currency unit, the
Dollar Equivalent of the Currency Unit, in each case as determined by the
Currency Determination Agent in the manner provided in paragraphs (g) or (h)
below.

          (f)  If the Holder of a Registered Security elects payment in a
specified Currency as provided for by paragraph (b) and a Conversion Event
occurs with respect to such elected Currency, such Holder shall receive payment
in the Currency in which payment would have been made in the absence of such
election; and if a Conversion Event occurs with respect to the Currency in which
payment would have been made in the absence of such election, such Holder shall
receive payment in Dollars.

          (g)  The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Currency Determination Agent as of each Valuation Date and
shall be obtained by converting the specified Foreign Currency into Dollars at
the Market Exchange Rate on the Conversion Date.

          (h)  The "Dollar Equivalent of the Currency Unit" shall be determined
by the Currency Determination Agent as of each Valuation Date and shall be the
sum obtained by adding together the results obtained by converting the Specified
Amount of each Component Currency into Dollars at the Market Exchange Rate on
the Valuation Date for such Component Currency.

          (i)  For purposes of this Section 2.14 the following terms shall have
the following meanings:

     A "Component Currency" shall mean any currency which, on the Conversion
Date, was a component currency of the relevant currency unit, including but not
limited to the Euro.

     A "Specified Amount" of a Component Currency shall mean the number of units
or fractions thereof which such Component Currency represented in the relevant
currency unit, including but not limited to the Euro, on the Conversion Date. If
after the Conversion Date the official unit of any Component Currency is altered
by way of combination or subdivision, the Specified Amount of such Component
Currency shall be divided or multiplied in the same proportion. If after the
Conversion Date two or more Component Currencies are consolidated into a single
currency, the respective Specified Amounts of such Component Currencies shall be
replaced by an amount in such single currency equal to the sum of the respective
Specified

                                       30
<Page>

Amounts of such consolidated Component Currencies expressed in such single
currency, and such amount shall thereafter be a Specified Amount and such single
currency shall thereafter be a Component Currency. If after the Conversion Date
any Component Currency shall be divided into two or more currencies, the
Specified Amount of such Component Currency shall be replaced by specified
amounts of such two or more currencies, the sum of which, at the Market Exchange
Rate of such two or more currencies on the date of such replacement, shall be
equal to the Specified Amount of such former Component Currency and such amounts
shall thereafter be Specified Amounts and such currencies shall thereafter be
Component Currencies. If, after the Conversion Date of the relevant currency
unit, including, but not limited to, the Euro, a Conversion Event (other than
any event referred to above in this definition of "Specified Amount") occurs
with respect to any Component Currency of such currency unit and is continuing
on the applicable Valuation Date, the Specified Amount of such Component
Currency shall, for purposes of calculating the Dollar Equivalent of the
Currency Unit, be converted into Dollars at the Market Exchange Rate in effect
on the Conversion Date of such Component Currency.

     "Market Exchange Rate" shall mean for any currency the noon Dollar buying
rate for that currency for cable transfers quoted in New York City on the
Valuation Date as certified for customs purposes by the Federal Reserve Bank of
New York. If such rates are not available for any reason with respect to one or
more Currencies for which an exchange rate is required, the Currency
Determination Agent shall use, in its sole discretion and without liability on
its part, such quotation of the Federal Reserve Bank of New York as of the most
recent available date, or quotations from one or more major banks in New York
City or in the country of issue of the currency in question, or such other
quotations as the Currency Determination Agent shall deem appropriate. Unless
otherwise specified by the Currency Determination Agent, if there is more than
one market for dealing in any currency by reason of foreign exchange regulations
or otherwise, the market to be used in respect of such currency shall be that
upon which a nonresident issuer of securities designated in such currency would
purchase such currency in order to make payments in respect of such securities.

     All decisions and determinations of the Currency Determination Agent
regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent
of the Currency Unit, the Market Exchange Rate and changes in Specified Amounts
as specified above shall be in its sole discretion and shall, in the absence of
manifest error, be conclusive for all purposes and irrevocably binding upon the
Company, the Trustee for the relevant series of Securities and all Holders of
such Securities.

     In the event that a Conversion Event has occurred with respect to a Foreign
Currency, the Company, after learning thereof, will immediately give notice
thereof to the Trustee (and the Trustee will promptly thereafter give notice in
the manner provided in Section 11.4 to the affected Holders) specifying the
Conversion Date. In the event that a Conversion Event has occurred with respect
to the Euro or any other currency unit in which Securities are denominated or
payable, the Company, after learning thereof, will immediately give notice
thereof to the Trustee (and the Trustee will promptly thereafter give notice in
the manner provided in Section 11.4 to the affected Holders) specifying the
Conversion Date and the Specified Amount of each Component Currency on the
Conversion Date. In the event of any subsequent change in any

                                       31
<Page>

Component Currency as set forth in the definition of Specified Amount above, the
Company, after learning thereof, will similarly give notice to the Trustee.

     The Trustee shall be fully justified and protected in relying on and acting
upon the information so received by it from the Company and the Currency
Determination Agent and shall not otherwise have any duty or obligation to
determine such information independently.

     SECTION 2.15   COMPLIANCE WITH CERTAIN LAWS AND REGULATIONS. If any
Unregistered Securities or Coupon Securities are to be issued in any Series of
Securities, the Company will use reasonable efforts to provide for arrangements
and procedures designed pursuant to then applicable laws and regulations, if
any, to ensure that Unregistered Securities or Coupon Securities are sold or
resold, exchanged, transferred and paid only in compliance with such laws and
regulations and without adverse consequences to the Company.

     SECTION 2.16   CUSIP NUMBERS. The Company in issuing the Securities may use
"CUSIP" or "ISIN" numbers (if then generally in use), and, if so, the Trustee
shall indicate the "CUSIP" or "ISIN" numbers of the Securities in notices of
redemption as a convenience to Holders; PROVIDED that any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any
change in the "CUSIP" or "ISIN" numbers.

     SECTION 2.17    SECURITIES IN GLOBAL FORM. If Securities of or within a
Series are issuable in whole or in part in global form, any such Security may
provide that it shall represent the aggregate amount of Outstanding Securities
from time to time endorsed thereon and may also provide that the aggregate
amount of Outstanding Securities represented thereby may from time to time be
reduced or increased to reflect exchanges. Any endorsement of a Security in
global form to reflect the amount, or any increase or decrease in the amount, or
changes in the rights of Holders, of Outstanding Securities represented thereby,
shall be made in such manner and by such Person or Persons as shall be specified
therein or in the Company order to be delivered to the Trustee pursuant to
Section 2.6 or 2.11. Subject to the provisions of Section 2.6 and, if
applicable, Section 2.13, the Trustee shall deliver and redeliver any Security
in permanent global form in the manner and upon instructions given by the Person
or Persons specified therein or in the applicable Company order. Any
instructions by the Company with respect to endorsement or deliver or redelivery
of a Security in global form shall be in writing but need not comply with
Section 11.5 and need not be accompanied by an Opinion of Counsel.

     The provisions of the last paragraph of Section 2.6 shall apply to any
Security in global form if such Security was never issued and sold by the
Company and the Company delivers to the Trustee the Security in global form
together with written instructions (which need not comply with Section 11.5 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last paragraph of Section 2.6.

                                       32
<Page>

     Notwithstanding the provisions of Section 3.1, unless otherwise specified
as contemplated by Section 2.6, payment of principal of and interest on any
Security in permanent global form shall be made to the Person or Persons
specified in such Security.

                                  ARTICLE THREE

                                    COVENANTS

     SECTION 3.1    PAYMENT OF PRINCIPAL AND INTEREST. The Company and, if
applicable, any Guarantor shall punctually pay or cause to be paid (in the
currency or currency unit in which the Securities of such Series and Coupons,
if any, are payable, except as otherwise provided pursuant to Section 2.5 for
the Securities of such Series and except as provided in Section 2.14(b), (e)
and (f) hereof) the principal of, and interest on, each of the Securities of
such Series in accordance with the terms of the Securities of such Series,
any Coupons appertaining thereto and this Indenture.

     The interest on Unregistered Securities shall be payable only upon
presentation and surrender of the several Coupons for such interest installments
as are evidenced thereby as they severally mature at the office of a Paying
Agent outside the United States. The interest on any temporary Unregistered
Security shall be paid, as to any installment of interest evidenced by a Coupon
attached thereto, if any, only upon presentation and surrender of such Coupon,
and, as to the other installments of interest, if any, only upon presentation of
such Securities for notation thereon of the payment of such interest.

     SECTION 3.2    OFFICES FOR PAYMENT, ETC. So long as any of the Securities
remain outstanding, the Company will maintain the following for each Series: an
office or agency (a) where the Securities may be presented for payment, (b)
where the Securities may be presented for registration of transfer and for
exchange as in this Indenture provided and (c) where notices and demands to or
upon the Company in respect of the Securities or of this Indenture may be
served. The Company will give to the Trustee written notice of the location of
any such office or agency and of any change of location thereof. In case the
Company shall fail to so designate or maintain any such office or agency or
shall fail to give such notice of the location or of any change in the location
thereof, presentations and demands may be made and notices may be served at the
corporate trust office. Unless otherwise specified pursuant to Section 2.5, the
Trustee is appointed Paying Agent and Registrar.

     So long as any Coupon Securities or Unregistered Securities of any Series
remain outstanding, the Company will (except as specified pursuant to Section
2.5) maintain one or more offices or agencies outside the United States in such
city or cities as may be specified elsewhere in this Indenture or as
contemplated by Section 2.5, and shall maintain such office or offices for a
period of two years (or any period thereafter for which it is necessary in order
to conform to United States tax laws or regulations) after the principal on such
Coupon Securities or Unregistered Securities has become due and payable, with
respect to such Series where Coupons appertaining to Securities of such Series
or Unregistered Securities of such Series may be surrendered or presented for
payment, or surrendered for exchange pursuant to Section 2.10 and where notices
and demands to or upon the Company in respect of Coupons appertaining to
Securities of such Series or the Unregistered Securities of such Series or of
this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location and any

                                       33
<Page>

change in the location, of any such office or agency. If at any time the Company
shall fail to maintain such required office or agency or shall fail to furnish
the Trustee with the address thereof, presentations, surrenders, notices and
demands in respect of Unregistered Securities may be made or served at the
Corporate Trust Office of the Trustee and the corporate trust office of any
authenticating agent appointed hereunder, and presentations, surrenders, notices
and demands in respect of Coupons appertaining to Securities of any Series and
Unregistered Securities may be made or served at the corporate trust office of
the Trustee in the other city or cities referred to above; and the Company
hereby appoints the Trustee and any authenticating agent appointed hereunder its
agents to receive all such presentations, surrenders, notices and demands.

     SECTION 3.3    APPOINTMENT TO FILL A VACANCY IN OFFICE OF TRUSTEE. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 6.10, a Trustee, so that there
shall at all times be a Trustee with respect to each Series of Securities
hereunder.

     SECTION 3.4    PAYING AGENTS. Whenever the Company shall appoint a Paying
Agent other than the Trustee with respect to the Securities of any Series, it
will cause such Paying Agent to execute and deliver to the Trustee an instrument
in which such Agent shall agree with the Trustee, subject to the provisions of
this Section,

          (a)  that it will hold all sums received by it as such Agent for the
     payment of the principal of or interest on the Securities of such Series or
     Coupons (whether such sums have been paid to it by the Company or by any
     other obligor on the Securities of such Series or Coupons) in trust for the
     benefit of the Holders of the Securities of such Series or Coupons or of
     the Trustee, and upon the occurrence of an Event of Default and upon the
     written request of the Trustee, pay over all such sums received by it to
     the Trustee,

          (b)  that it will give the Trustee notice of any failure by the
     Company (or by any other obligor on the Securities of such Series) to make
     any payment of the principal of or interest on the Securities of such
     Series or Coupons when the same shall be due and payable, and

          (c)  that it will give the Trustee notice of any change of address of
     any Holder of which it is aware.

     The Company will, on or prior to each due date of the principal of or
interest on the Securities of such Series or Coupons, deposit with the Paying
Agent a sum sufficient to pay such principal or interest so becoming due, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of any failure to take such action.

     If the Company shall act as its own Paying Agent with respect to the
Securities of any Series or Coupons, it will, on or before each due date of the
principal of or interest on the Securities of such Series or Coupons, set aside,
segregate and hold in trust for the benefit of the Holders of the Securities of
such Series or Holders of such Coupons a sum sufficient to pay such

                                       34
<Page>

principal or interest so becoming due. The Company will promptly notify the
Trustee of any failure to take such action.

     Anything in this Section to the contrary notwithstanding, the Company may
at any time, for the purpose of obtaining a satisfaction and discharge with
respect to one or more or all Series of Securities or Coupons hereunder, or for
any other reason, pay or cause to be paid to the Trustee all sums held in trust
for any such Series by the Company or any Paying Agent hereunder, as required by
this Section, such sums to be held by the Trustee upon the trusts herein
contained.

     Anything in this Section to the contrary notwithstanding, the agreement to
hold sums in trust as provided in this Section is subject to the provisions of
Sections 10.3 and 10.4.

     SECTION 3.5    ADDITIONAL AMOUNTS. If Securities of a Series provide for
the payment of additional amounts to any Holder who is a non-United States
Person in respect of any tax, assessment or governmental charge ("Additional
Amounts"), the Company will pay to the Holder of any Security of such Series or
any Coupon appertaining thereto such Additional Amounts as may be so provided by
Section 2.5. Whenever in this Indenture there is mentioned, in any context, the
payment of the principal of or interest on, or in respect of, any Security of a
Series or payment of any related Coupon or the net proceeds received on the sale
or exchange of a Security of a Series, such mention shall be deemed to include
mention of the payment of Additional Amounts provided for by the terms of such
Series established pursuant to Section 2.5 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 provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not
made.

     Except as otherwise specified as contemplated by Section 2.5, if the
Securities of a Series provide for the payment of Additional Amounts, at least
10 days prior to each date of payment of principal or interest on which any
Additional Amount shall be payable, the Company will furnish the Trustee and the
Company's principal Paying Agent or Paying Agents, if other than the Trustee,
with a compliance certificate instructing the Trustee and such Paying Agent or
Paying Agents whether such payment of principal of or interest on the Securities
of that Series shall be made to Holders of Securities of that Series or any
related Coupons who are non-United States Persons without withholding for or on
account of any tax, assessment or other governmental charge described in the
Securities of that Series. If any such withholding shall be required, then

                                       35
<Page>

such compliance certificate shall specify by country the amount, if any,
required to be withheld on such payments to such Holders of Securities of that
Series or related Coupons and the Company will 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 or in the event the Trustee shall
not withhold or deduct any sums as a result of the non-receipt of a compliance
certificate pursuant to this Section.

     SECTION 3.6    CALCULATION OF ORIGINAL ISSUE DISCOUNT. The Company shall
file with the Trustee promptly at the end of each calendar year (i) a written
notice specifying the amount of original issue discount (including daily rates
and accrual periods) accrued on Outstanding Securities as of the end of such
year and (ii) such other specific information relating to such original issue
discount as may then be relevant under the Internal Revenue Code of 1986, as
amended from time to time.

                                  ARTICLE FOUR

                    SECURITYHOLDERS' LISTS AND REPORTS BY THE
                             ISSUER AND THE TRUSTEE

     SECTION 4.1    COMPANY TO FURNISH TRUSTEE INFORMATION AS TO NAMES AND
ADDRESSES OF SECURITYHOLDERS. The Company covenants and agrees that it will
furnish or cause to be furnished to the Trustee for the Securities of each
Series a list in such form as the Trustee may reasonably require of the names
and addresses of the Holders of the Registered Securities of each Series:

          (a)  semiannually and not more than 15 days after each record date for
     the payment of interest on such Securities, as hereinabove specified, as of
     such record date and on dates to be determined pursuant to Section 2.5 for
     non-interest bearing securities in each year, and

          (b)  at such other times as the Trustee may request in writing, within
     30 days after receipt by the Company of any such request such list to be as
     of a date not more than 15 days prior to the time such information is
     furnished,

PROVIDED that if and so long as the Trustee shall be the Security registrar for
such Series, such list shall not be required to be furnished but in any event
the Company shall be required to furnish such information concerning the Holders
of Coupon Securities and Unregistered Securities which is known to it; provided,
further, that the Company shall have no obligation to investigate any matter
relating to any Holder of an Unregistered Security or any Holder of a Coupon.

     SECTION 4.2    PRESERVATION AND DISCLOSURE OF SECURITYHOLDERS' LISTS.

          (a)  The Trustee for the Securities of each Series shall preserve, in
as current a form as is reasonably practicable, all information as to the names
and addresses of the Holders of each Series of Securities contained in the most
recent list furnished to it as provided in Section 4.1 or maintained by the
Trustee in its capacity as Security registrar for such Series, if so acting.

                                       36
<Page>

The Trustee may destroy any list furnished to it as provided in Section 4.1 upon
receipt of a new list so furnished.

          (b)  In case three or more Holders of Registered Securities of any
Series (hereinafter referred to as "applicants") apply in writing to the Trustee
and furnish to the Trustee reasonable proof that each such applicant has owned a
Security for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other Holders of Securities of a particular Series (in which
case the applicants must all hold Securities of such Series) or with Holders of
all Securities with respect to their rights under this Indenture or under such
Securities and such application is accompanied by a copy of the form of proxy or
other communication which such applicants propose to transmit, then the Trustee
shall, within five business days after the receipt of such application, at its
election, either

               (i)       afford to such applicants access to the information
     preserved at the time by the Trustee in accordance with the provisions of
     subsection (a) of this Section 4.2, or

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

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

                                       37
<Page>

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

     SECTION 4.3    REPORTS BY THE COMPANY. The Company covenants:

          (a)  to file with the Trustee for the Securities of each Series,
within 15 days after the Company is required to file the same with the
Commission, copies of the annual reports and of the information, documents, and
other reports (or copies of such portions of any of the foregoing as the
Commissioner may from time to time by rules and regulations prescribe) which the
Company may be required to file with the Commission pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934, or if the Company is not

condition contained in this Indenture and whether or not they have knowledge
of any default with respect to such covenants, agreements or conditions and
if so, specifying each such default and the nature thereof.  For purposes of
this paragraph, such compliance shall be determined without regard to any
period of grace or requirement of notice provided under this Indenture.

     Delivery of such reports, information and documents to the Trustee is for

                   REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                               ON EVENT OF DEFAULT

     SECTION 5.1    EVENT OF DEFAULT DEFINED; ACCELERATION OF MATURITY; WAIVER
OF DEFAULT. In case one or more of the following Events of Default (unless it is
either inapplicable to a particular Series or it is specifically deleted from or
modified in the instrument establishing such Series and the form of Security for
such Series) shall have occurred and be continuing with respect to any Series of
Securities, that is to say:

          (a)  default in the payment of any installment of interest upon any
Security of such Series as and when the same shall become due and payable, and
continuance of such default for a period of 30 days; or

          (b)  default in the payment of the principal of the Securities of such
Series as and when the same shall become due and payable either at maturity,
upon redemption (for any sinking fund payment or otherwise), by declaration or
otherwise; or

          (c)  failure on the part of the Company duly to observe or perform any
other of the covenants or agreements on the part of the Company in the
Securities of such Series, or in this Indenture contained and relating to such
Series, for a period of 90 days after the date on which written notice
specifying such failure and requiring the Company to remedy the same and stating
that such notice is a "Notice of Default" hereunder shall have been given by
registered or certified mail to the Company by the Trustee for the Securities of
such Series, or to the Company and the Trustee by the Holders of at least
twenty-five percent in aggregate principal amount at maturity of the Securities
of such Series at the time outstanding; or

          (d)  the Company shall make an assignment for the benefit of
creditors, or shall file a petition in bankruptcy; or the Company shall be
adjudicated insolvent or bankrupt, or shall petition or shall apply to any court
having jurisdiction in the premises for the appointment

                                       39
<Page>

of a receiver, trustee, liquidator or sequestrator of, or for, the Company or
any substantial portion of the property of the Company; or the Company shall
commence any proceeding relating to the Company or any substantial portion of
the property of the Company under any insolvency, reorganization, arrangement,
or readjustment of debt, dissolution, winding-up, adjustment, composition or
liquidation law or statute of any jurisdiction, whether now or hereafter in
effect (hereinafter in this subsection (d) called "Proceeding"); or if there
shall be commenced against the Company any Proceeding and an order approving the
petition shall be entered, or such Proceeding shall remain undischarged for a
period of 60 days; or a receiver, trustee, liquidator or sequestrator of, or
for, the Company or any substantial portion of the property of the Company shall
be appointed and shall not be discharged within a period of 60 days; or the
Company by any act shall indicate consent to or approval of or acquiescence in
any Proceeding or the appointment of a receiver, trustee, liquidator or
sequestrator of, or for, the Company or any substantial portion of the property
of the Company; provided that a resolution or order for winding-up the Company
with a view to its consolidation, amalgamation or merger with another company or
the transfer of its assets as a whole, or substantially as a whole, to such
other company as provided in Section 9.1 shall not make the rights and remedies
herein enforceable under this subsection (d) of Section 5.1 if such
last-mentioned company shall, as a part of such consolidation, amalgamation,
merger or transfer, and within 60 days from the passing of the resolution or the
date of the order, comply with the conditions to that end stated in Section 9.1;
or

          (e)  any other Event of Default provided in the Supplemental Indenture
or resolution of the Board of Directors under which such Series of Securities is
issued or in the form of Security for such Series;

then and in each and every such case, so long as such Event of Default with
respect to such Series shall not have been remedied or waived, unless the
principal of all Securities of such Series shall have already become due and
payable, either the Trustee for such Series or the Holders of not less than
twenty-five percent in aggregate principal amount at maturity of the Securities
of such Series then Outstanding hereunder, by notice in writing to the Company
(and to the Trustee if given by such Holders), may declare the principal (or, in
the case of Original Issue Discount Securities, such principal amount as may be
determined in accordance with the terms thereof) of all the Securities of such
Series to be due and payable immediately, and upon any such declaration the same
shall become and shall be immediately due and payable, anything in this
Indenture or in the Securities of such Series contained to the contrary
notwithstanding. This provision, however, is subject to the condition that if at
any time after the principal of the Securities of such Series (or, in the case
of Original Issue Discount Securities, such principal amount as may be
determined in accordance with the terms thereof) shall have been so declared due
and payable, and before any judgment or decree for the payment of the moneys due
shall have been obtained or entered as hereinafter provided, the Company shall
pay or shall deposit with the Trustee a sum sufficient to pay in the currency or
currency unit in which the Securities of such Series are payable (except as
otherwise provided pursuant to Section 2.5 for the Securities of such Series and
except as provided in Section 2.14(b), (e) and (f) hereof) all matured
installments of interest, if any, upon all the Securities of such Series and the
principal of any and all Securities of such Series which shall have become due
otherwise than by such acceleration (with interest upon such principal and, to
the extent that payment of such interest is enforceable under applicable law,
upon overdue installments of interest, at the rate borne by the Securities of
such Series (or, in the case of Original Issue Discount Securities, at the yield
to

                                       40
<Page>

maturity) to the date of such payment or deposit) and in Dollars such amount
as shall be sufficient to cover reasonable compensation to the Trustee, its
agents, attorneys and counsel and all other expenses and liabilities incurred,
and all advances made, by the Trustee, its agents, attorneys and counsel and any
and all defaults under this Indenture, other than the nonpayment of the
principal of Securities of such Series which shall have become due by such
acceleration, shall have been remedied then and in every such case the Holders
of a majority in aggregate principal amount at maturity of the Securities of
such Series then Outstanding, by written notice to the Company and to the
Trustee for the Securities of such Series, may waive all defaults and rescind
and annul such declaration and its consequences; but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default
or shall impair any right consequent thereon.

     SECTION 5.2    COLLECTION OF INDEBTEDNESS BY TRUSTEE; TRUSTEE MAY PROVE
DEBT. The Company covenants that (a) in case default shall be made in the
payment of any installment of interest on any of the Securities of any Series
when such interest shall have become due and payable, and such default shall
have continued for a period of 30 days or (b) in case default shall be made in
the payment of all or any part of the principal of any of the Securities of any
Series when the same shall have become due and payable, whether upon maturity of
the Securities of such Series or upon any redemption or by declaration or
otherwise, then upon demand of the Trustee for the Securities of such Series,
the Company will pay to the Trustee for the Securities of such Series for the
benefit of the Holders of the Securities of such Series and the Holders of any
Coupons appertaining thereto the whole amount that then shall have become due
and payable on all Securities of such Series or such Coupons for principal of or
interest, as the case may be (with interest to the date of such payment upon the
overdue principal and, to the extent that payment of such interest is
enforceable under applicable law, on overdue installments of interest at the
same rate as the rate of interest specified in the Securities of such Series);
and in addition thereto, such further amount as shall be sufficient to cover the
costs and expenses of collection, including reasonable compensation to the
Trustee and each predecessor Trustee, their respective agents, attorneys and
counsel, and any expenses and liabilities incurred, and all advances made, by
the Trustee and each predecessor Trustee.

     Until such demand is made by the Trustee, the Company may pay the principal
of and interest on the Securities of any Series to the persons entitled thereto,
whether or not the principal of and interest on the Securities of such Series
are overdue.

     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee for the Securities of such Series, in its own name and as
trustee of an express trust, shall be entitled and empowered to institute any
action or proceedings at law or in equity for the collection of the sums so due
and unpaid, and may prosecute any such action or proceedings to judgment or
final decree, and may enforce any such judgment or final decree against the
Company or other obligor upon such Securities and collect in the manner provided
by law out of the property of the Company or other obligor upon such Securities
and Coupons, wherever situated, the moneys adjudged or decreed to be payable.

     In case there shall be pending proceedings relative to the Company or any
other obligor upon the Securities and Coupons under Title 11 of the United
States Code or any other applicable Federal or state bankruptcy, insolvency or
other similar law, or in case a receiver,

                                       41
<Page>

assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or
similar official shall have been appointed for or taken possession of the
Company or its property or such other obligor, or in case of any other
comparable judicial proceedings relative to the Company or other obligor under
the Securities of any Series and Coupons, if any, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of any 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 pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such proceedings or otherwise:

          (a)  to file and prove a claim or claims for the whole amount of
     principal (or, if the Securities of such Series are Original Issue Discount
     Securities, such portion of the principal amount as may be due and payable
     with respect to the Securities of such Series pursuant to a declaration in
     accordance with Section 5.1 hereof) and interest owing and unpaid in
     respect of the Securities of any Series, 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 reasonable compensation to the Trustee
     and each predecessor Trustee, and their respective agents, attorneys and
     counsel, and for reimbursement of all expenses and liabilities incurred,
     and all advances made, by the Trustee and each predecessor Trustee,) and of
     the Securityholders and the Holders of any Coupons appertaining thereto
     allowed in any judicial proceedings relative to the Company or other
     obligor upon all Securities of any Series, or to the creditors or property
     of the Company or such other obligor,

          (b)  unless prohibited by applicable law and regulations, to vote on
     behalf of the holders of the Securities of any Series in any election of a
     trustee or a standby trustee in arrangement, reorganization, liquidation or
     other bankruptcy or insolvency proceedings or person performing similar
     functions in comparable proceedings, and

          (c)  to collect and receive any moneys or other property payable or
     deliverable on any such claims, and to distribute all amounts received with
     respect to the claims of the Securityholders and of the Trustee on their
     behalf; and any trustee, receiver, or liquidator, custodian or other
     similar official is hereby authorized by each of the Holders to make
     payments to the Trustee for the Securities of such Series, and, in the
     event that such Trustee shall consent to the making of payments directly to
     the Securityholders, to pay to such Trustee such amounts as shall be
     sufficient to cover reasonable compensation to such Trustee, each
     predecessor Trustee and their respective agents, attorneys and counsel, and
     all other expenses and liabilities incurred, and all advances made, by such
     Trustee and each predecessor Trustee and all other amounts due to such
     Trustee or any predecessor Trustee pursuant to Section 6.6.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities of any Series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding except, as aforesaid, to vote for the
election of a trustee in bankruptcy or similar person.

                                       42
<Page>

     All rights of action and of asserting claims under this Indenture, or under
any of the Securities or any Coupon appertaining thereto, may be enforced by the
Trustee for the Securities of such Series without the possession of any of the
Securities of such Series or any Coupon appertaining thereto or the production
thereof at any trial or other proceedings relative thereto, and any such action
or proceedings instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment, subject to the
payment of the expenses, disbursements and compensation of the Trustee, each
predecessor Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Securities and Holders of any Coupons in
respect of which such action was taken.

     In any proceedings brought by the Trustee for the Securities of such Series
(and also any proceedings involving the interpretation of any provision of this
Indenture to which the Trustee shall be a party), the Trustee shall be held to
represent all the Holders of the Securities and Coupons appertaining thereto in
respect to which such action was taken, and it shall not be necessary to make
any Holders of such Securities and Coupons appertaining thereto parties to any
such proceedings.

     SECTION 5.3    APPLICATION OF PROCEEDS. Any moneys collected by the Trustee
for the Securities of such Series pursuant to this Article in respect of the
Securities of any Series shall be applied in the following order at the date or
dates fixed by such Trustee and, in case of the distribution of such moneys on
account of principal or interest, upon presentation of the several Securities
and any Coupons appertaining thereto in respect of which moneys have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such Series in reduced principal amounts in exchange for the
presented Securities of like Series if only partially paid, or upon surrender
thereof if fully paid:

          FIRST:    To the payment of costs and expenses applicable to such
     Series in respect of which moneys have been collected, including reasonable
     compensation to the Trustee and each predecessor Trustee and their
     respective agents and attorneys and of all expenses and liabilities
     incurred, and all advances made, by the Trustee and each predecessor
     Trustee and all other amounts due to the Trustee or any predecessor Trustee
     pursuant to Section 6.6;

          SECOND:   In case the principal of the Securities of such Series in
     respect of which moneys have been collected shall not have become and be
     then due and payable, to the payment of interest on the Securities of such
     Series in default in the order of the maturity of the installments of such
     interest, with interest (to the extent that such interest has been
     collected by the Trustee) upon the overdue installments of interest at the
     same rate as the rate of interest specified in such Securities, such
     payments to be made ratably to the persons entitled thereto, without
     discrimination or preference;

          THIRD:    In case the principal of the Securities of such Series in
     respect of which moneys have been collected shall have become and shall be
     then due and payable, to the payment of the whole amount then owing and
     unpaid upon all the Securities of such Series for principal and interest,
     with interest upon the overdue principal, and (to the extent that payment
     of such interest is permissible by law and that such interest has been
     collected by the Trustee) upon overdue installments of interest at the same
     rate as the rate

                                       43
<Page>

     of interest specified in the Securities of such Series; and in case such
     moneys shall be insufficient to pay in full the whole amount so due and
     unpaid upon the Securities of such Series, then to the payment of such
     principal and interest without preference or priority of principal over
     interest or of interest over principal, or of any installment of interest
     over any other installment of interest, or of any Security of such Series
     over any other Security of such Series, ratably to the aggregate of such
     principal and accrued and unpaid interest; and

          FOURTH:   To the payment of the remainder, if any, to the Company or
     any other person lawfully entitled thereto.

     SECTION5.4     SUITS FOR ENFORCEMENT. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

     SECTION 5.5    RESTORATION OF RIGHTS ON ABANDONMENT OF PROCEEDINGS. In case
the Trustee for the Securities of any Series shall have proceeded to enforce any
right under this Indenture and such proceedings shall have been discontinued or
abandoned for any reason, or shall have been determined adversely to the
Trustee, then and in every such case the Company and the Trustee shall be
restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Company, the Trustee and the Securityholders
shall continue as though no such proceedings had been taken.

     SECTION 5.6    LIMITATIONS ON SUITS BY SECURITYHOLDERS. No Holder of any
Security of any Series or Holder of any Coupon shall have any right by virtue or
by availing of any provision of this Indenture to institute any action or
proceeding at law or in equity or in bankruptcy or otherwise upon or under or
with respect to this Indenture, or for the appointment of a trustee, receiver,
liquidator, custodian or other similar official or for any other remedy
hereunder, unless such Holder previously shall have given to the Trustee written
notice of default and of the continuance thereof, as hereinbefore provided, and
unless also the Holders of not less than 25% in aggregate principal amount of
the Securities of such Series then Outstanding shall have made written request
upon the Trustee to institute such action or proceedings in its own name as
trustee hereunder and shall have offered to the Trustee such reasonable
indemnity, as it may require against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity shall have failed to institute any
such action or proceeding and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to Section 5.9; it being
understood and intended, and being expressly covenanted by the taker and Holder
of every Security and by a Holder of each Coupon appertaining thereto with every
other taker and Holder of a Security or Holder of any Coupon appertaining
thereto and the Trustee, that no one or more Holders of Securities of any Series
or one or more Holders of any Coupons appertaining thereto shall have any right
in any manner whatever, by virtue or by availing of any provision of this
Indenture to affect, disturb or

                                       44
<Page>

prejudice the rights of any other such Holder of Securities or any other Holders
of such Coupons, or to obtain or seek to obtain priority over or preference to
any other such Holder or to enforce any right under this Indenture, except in
the manner herein provided and for the equal, ratable and common benefit of all
Holders of Securities of the applicable Series and all the Holders of Coupons
appertaining thereto. For the protection and enforcement of the provisions of
this Section, each and every Securityholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

     SECTION 5.7    UNCONDITIONAL RIGHT OF SECURITYHOLDERS TO INSTITUTE CERTAIN
SUITS. Notwithstanding any provision in this Indenture and any provision of any
Security or Coupon, the right of any Holder of any Security and the right of any
Holder of any Coupon appertaining thereto to receive payment of the principal of
and interest on such Security at the respective rates, in the respective amount
and in the currency or currency unit therein prescribed on or after the
respective due dates expressed in such Security, or to institute suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

     SECTION 5.8    POWERS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER
OF DEFAULT. Except as provided in Section 5.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the Securityholders is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

     No delay or omission of the Trustee or of any Securityholder to exercise
any right or power accruing upon any Event of Default occurring and continuing
as aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default or an acquiescence therein; and, subject to
Section 5.6, every power and remedy given by this Indenture or by law to the
Trustee, to the Securityholders or to the Holder of any Coupon appertaining
thereto may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee, the Securityholders or Holders of any Coupon.

     SECTION 5.9    CONTROL BY SECURITYHOLDERS. The Holders of a majority in
aggregate principal amount of the Securities of each Series affected (with each
Series treated as a separate class) at the time Outstanding 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 by this Indenture;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the
provisions of Section 6.1) the Trustee shall have the right to decline to follow
any such direction if the Trustee, being advised by counsel, shall determine
that the action or proceeding so directed may not lawfully be taken or if the
Trustee in good faith by its board of directors, the executive committee, or a
trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would involve the Trustee
in personal liability or if the Trustee in good faith shall so determine that
the actions or forbearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all Series
or of the

                                       45
<Page>

Holders of any Coupons appertaining thereto so affected not joining in the
giving of said direction, it being understood that (subject to Section 6.1) the
Trustee shall have no duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Holders.

     Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction or directions by Securityholders.

     SECTION 5.10   WAIVER OF PAST DEFAULTS. Prior to the declaration of the
acceleration of the maturity of the Securities of any Series as provided in
Section 5.1, the Holders of a majority in aggregate principal amount of the
Securities of such Series at the time Outstanding may on behalf of the Holders
of all the Securities of such Series and Holders of all Coupons, if any,
appertaining thereto waive any past default hereunder or its consequences,
except a default in the payment of the principal of or interest on any of the
Securities of such Series. In the case of any such waiver, the Company, the
Trustee, the Holders of the Securities of such Series and the Holder of any
Coupon appertaining thereto shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

     Upon any such waiver, such default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured and not to have occurred for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

     SECTION 5.11   TRUSTEE TO GIVE NOTICE OF DEFAULT, BUT MAY WITHHOLD IN
CERTAIN CIRCUMSTANCES. The Trustee shall transmit to the Securityholders of any
Series notice in the manner and to the extent provided in Section 11.4, of all
defaults which have occurred with respect to such Series, such notice to be
transmitted within 90 days after the occurrence thereof, unless such defaults
shall have been cured before the giving of such notice (the term "default" or
"defaults" for the purposes of this Section being hereby defined to mean any
event or condition which is, or with notice or lapse of time or both would
become, an Event of Default); provided that, except in the case of default in
the payment of the principal of or interest on any of the Securities of such
Series or any default in the payment of any sinking fund installment or
analogous obligation in respect of any of the Securities of such Series, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee, or a trust committee of directors
or trustees or Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interests of the Securityholders of
such Series.

     SECTION 5.12   RIGHT OF COURT TO REQUIRE FILING OF UNDERTAKING TO PAY
COSTS. All parties to this Indenture agree, and each Holder of any Security and
each Holder of any Coupon, by his acceptance thereof, shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken, suffered or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees and expenses,

                                       46

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 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of
Securityholders of any Series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such Series, or, in the case of
any suit relating to or arising under clause (d) of Section 5.1 (if the suit

aggregate principal amount of Securities Outstanding affected thereby, or in the
case of any suit relating to or arising under clause (d) (if the suit under

Section 5.1, 10% in aggregate principal amount of all Securities Outstanding, or
to any suit instituted by any Securityholder for the enforcement of the payment
of the principal of or interest on any Security on or after the due date
expressed in such Security.

                                   ARTICLE SIX

                             CONCERNING THE TRUSTEE

     SECTION 6.1    DUTIES AND RESPONSIBILITIES OF THE TRUSTEE; DURING DEFAULT;
PRIOR TO DEFAULT. With respect to the Holders of any Series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a particular Series and after the curing or waiving
of all Events of Default which may have occurred with respect to such Series,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default with respect to the
Securities of a Series has occurred (which has not been cured or waived) of
which a Responsible Officer has actual knowledge, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of such person's own affairs.

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

          (a)  prior to the occurrence of an Event of Default with respect to
     the Securities of any Series and after the curing or waiving of all such
     Events of Default with respect to such Series which may have occurred:

               (i)  the duties and obligations of the Trustee with respect to
          the Securities of any Series shall be determined solely by the express
          provisions of this Indenture, and the Trustee shall not be liable
          except for the performance of such duties and obligations as are
          specifically set forth in this Indenture, and no implied covenants or
          obligations shall be read into this Indenture against the Trustee; and

               (ii) in the absence of bad faith on the part of the Trustee, the
          Trustee may conclusively rely, as to the truth of the statements and
          the correctness of the opinions expressed therein, upon any
          statements, certificates or opinions furnished to the Trustee and
          conforming to the requirements of this Indenture; but

                                       47
<Page>

          in the case of any such statements, certificates or opinions which by
          any provision hereof are specifically required to be furnished to the
          Trustee, the Trustee shall be under a duty to examine the same to
          determine whether or not they conform to the requirements of this
          Indenture;

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

          (c)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders pursuant to Section 5.9 relating to the time, method and
     place of conducting any proceeding for any remedy available to the Trustee,
     or exercising any trust or power conferred upon the Trustee, under this
     Indenture.

     None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

     Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the conditions of this Section
6.1.

     SECTION 6.2    CERTAIN RIGHTS OF THE TRUSTEE. Subject to Section 6.1:

          (a)  the Trustee may conclusively rely and shall be protected in
acting or refraining from acting upon any resolution, Officers' Certificate or
any other certificate, statement, instrument, opinion, report, notice, request,
consent, order, bond, debenture, note, coupon, security or other paper or
document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

          (b)  any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the secretary or any assistant secretary of the Company;

          (c)  the Trustee may consult with counsel of its selection and any
advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted to be taken by it
hereunder in good faith and in accordance with such advice or Opinion of
Counsel;

          (d)  the Trustee shall be under no obligation to exercise any of the
trusts or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders pursuant to the provisions of this
Indenture, unless such Securityholders shall

                                       48
<Page>

have offered to the Trustee security or indemnity satisfactory to it against the
costs, expenses and liabilities which might be incurred therein or thereby;

          (e)  the Trustee shall not be liable for any action taken or omitted
by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture;

          (f)  prior to the occurrence of any Event of Default hereunder and
after the curing or waiving of all Events of Default, the Trustee shall not be
bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, appraisal, bond, debenture, note, coupon,
security, or other paper or document unless requested in writing to do so by the
Holders of not less than a majority in aggregate principal amount of the
Securities of all Series affected then Outstanding; provided that, if the
payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such expenses or liabilities as a condition to
proceeding; the reasonable expenses of every such investigation shall be paid by
the Company or, if paid by the Trustee or any predecessor Trustee, shall be
repaid by the Company upon demand;

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

          (h)  the Trustee shall not be deemed to have notice of any Default or
Event of Default (other than any Event of Default under Section 5.1(a) or
5.1(b)) unless a Responsible Officer of the Trustee has actual knowledge thereof
or unless written notice of such Default or Event of Default is received by the
Trustee at the Corporate Trust Office of the Trustee;

          (i)  the rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and each agent, custodian and other Person employed
to act hereunder; and

          (j)  the Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by and person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

     SECTION 6.3    TRUSTEE NOT RESPONSIBLE FOR RECITALS, DISPOSITION OF
SECURITIES OR APPLICATION OF PROCEEDS THEREOF. The recitals contained herein and
in the Securities, except the Trustee's certificate of authentication, shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of the
Securities or the

                                       49
<Page>

Coupons. The Trustee represents that it is duly authorized to execute and
deliver this Indenture and perform its obligations hereunder. The Trustee shall
not be accountable for the use or application by the Company of any of the
Securities or of the proceeds thereof.

     SECTION 6.4    TRUSTEE AND AGENTS MAY HOLD SECURITIES; COLLECTIONS, ETC.
The Trustee, any Paying Agent, Security registrar, or any agent of the Company
or the Trustee, in its individual or any other capacity, may become the owner or
pledgee of Securities or Coupons with the same rights it would have if it were
not the Trustee or such agent and, subject to Sections 6.8 and 6.13, if
operative, may otherwise deal with the Company and receive, collect, hold and
retain collections from the Company with the same rights it would have if it
were not the Trustee or such agent.

     SECTION 6.5    MONEYS HELD BY TRUSTEE. Subject to the provisions of Section
10.4 hereof, all moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required by
mandatory provisions of law. Neither the Trustee nor any agent of the Company or
the Trustee shall be under any liability for interest on any moneys received by
it hereunder.

     SECTION 6.6    COMPENSATION AND INDEMNIFICATION OF TRUSTEE AND ITS PRIOR
CLAIM. The Company and the Guarantor shall pay to the Trustee from time to time,
and the Trustee shall be entitled to, such compensation as shall be agreed in
writing between the Company, the Guarantor and the Trustee in Dollars (which
shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) and the Company and the Guarantor covenant and
agree to pay or reimburse the Trustee and each predecessor Trustee upon its
request in Dollars for all reasonable expenses, disbursements and advances
incurred or made by or on behalf of it in accordance with any of the provisions
of this Indenture (including the reasonable compensation and the expenses and
disbursements of its counsel and of all agents and other persons not regularly
in its employ) except any such expense, disbursement or advance as may arise
from its negligence or bad faith. The Company and the Guarantor also covenant to
indemnify the Trustee and each predecessor Trustee for, and to hold it harmless
against, any and all loss, liability, damage, claim or expense, including taxes
(other than taxes based on the income of the Trustee), incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder, including the costs and expenses of defending itself against
or investigating any claim (whether asserted by the Company, the Guarantor, a
Holder or any other Person) of liability in the premises. The obligations of the
Company and the Guarantor under this Section to compensate and indemnify the
Trustee and each predecessor Trustee and to pay or reimburse the Trustee and
each predecessor Trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Indenture. Such additional indebtedness shall be a senior
claim to that of the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the Holders
of particular Securities or the Holders of particular Coupons, and the
Securities are hereby subordinated to such senior claim.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(d), the expenses (including the
reasonable charges and expenses

                                       50
<Page>

of its counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable Federal or state bankruptcy,
insolvency or other similar law.

     SECTION 6.7    RIGHT OF TRUSTEE TO RELY ON OFFICERS' CERTIFICATE, ETC.
Subject to Sections 6.1 and 6.2, whenever in the administration of the trusts of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate complying with Section 11.5 delivered to the Trustee, and
such certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or
omitted by it or under the provisions of this Indenture upon the faith thereof.

     SECTION 6.8    DISQUALIFICATION OF TRUSTEE; CONFLICTING INTERESTS. If the
Trustee for the Securities of any Series has or shall acquire any conflicting
interest, as defined in the Trust Indenture Act, it shall, within 90 days after
ascertaining that it has such conflicting interest, and if the default (as
defined in the Trust Indenture Act) to which such conflicting interest relates
has not been cured or waived or otherwise eliminated before the end of such
90-day period, the Trustee shall, either eliminate such conflicting interest or
resign in the manner and with the effect specified in the Trust Indenture Act
and this Indenture.

     SECTION 6.9    PERSONS ELIGIBLE FOR APPOINTMENT AS TRUSTEE. The Trustee for
each Series of Securities hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
of any State or the District of Columbia having a combined capital and surplus
of at least $50,000,000, and which is authorized under such laws to exercise
corporate trust powers and is subject to supervision or examination by Federal,
State or District of Columbia authority. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 6.10.

     SECTION 6.10   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR TRUSTEE.

          (a)  The Trustee, or any trustee or trustees hereafter appointed, may
at any time resign with respect to one or more or all Series of Securities by
giving written notice of resignation to the Company and by mailing notice
thereof to the Holders in the manner and to the extent provided in Section 11.4.
Upon receiving such notice of resignation, the Company shall promptly appoint a
successor trustee or trustees with respect to the applicable Series by written
instrument in duplicate, executed by authority of the Board of Directors, one
copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor trustee or trustees. If no successor trustee shall have
been so appointed with respect to any Series and have accepted appointment
within 30 days after the mailing of such notice of resignation, the resigning
trustee may petition, at the expense of the Company, any court of competent

                                       51
<Page>

jurisdiction for the appointment of a successor trustee, or any Securityholder
who has been a bona fide Holder of a Security or Securities of the applicable
Series for at least six months may, subject to the provisions of Section 5.12,
on behalf of himself and all others similarly situated, petition any such court
for the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

          (b)  In case at any time any of the following shall occur:

               (i)       the Trustee shall fail to comply with the provisions of
     Section 6.8 with respect to any Series of Securities after written request
     therefor by the Company or by any Securityholder who has been a bona fide
     Holder of a Security or Securities of such Series for at least six months
     unless the Trustee's duty to resign is stayed in accordance with the
     provisions of Section 310(b) of the Trust Indenture Act; or

               (ii)      the Trustee shall cease to be eligible in accordance
     with the provisions of Section 6.9 and shall fail to resign after written
     request therefor by the Company or by any Securityholder; or

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

then, in any such case, the Company may remove the Trustee with respect to the
applicable Series of Securities and appoint a successor trustee for such Series
by written instrument, in duplicate, executed by order of the Board of Directors
of the Company, one copy of which instrument shall be delivered to the Trustee
so removed and one copy to the successor trustee, or, subject to the provisions
of Section 5.12, any Securityholder who has been a bona fide Holder of a
Security or Securities of such Series for at least six months may on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
trustee with respect to such Series. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

          (c)  The Holders of a majority in aggregate principal amount of the
Securities of each Series at the time Outstanding may at any time remove the
Trustee with respect to Securities of such Series and appoint a successor
trustee with respect to the Securities of such Series by delivering to the
Trustee so removed, to the successor trustee so appointed and to the Company the
evidence provided for in Section 7.1 of the action in that regard taken by the
Securityholders.

     If no successor Trustee shall have been appointed with respect to such
series within 30 days after the mailing of such notice of removal, the Trustee
being removed may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

                                       52
<Page>

          (d)  Any resignation or removal of the Trustee with respect to any
Series and any appointment of a successor trustee with respect to such Series
pursuant to any of the provisions of this Section 6.10 shall become effective
upon acceptance of appointment by the successor trustee as provided in Section
6.11.

     SECTION 6.11   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR TRUSTEE. Any
successor trustee appointed as provided in Section 6.10 shall execute and
deliver to the Company and to its predecessor Trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee with respect to all or any applicable Series shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties and obligations
with respect to such Series of its predecessor hereunder, with like effect as if
originally named as trustee for such Series hereunder; but, nevertheless, on the
written request of the Company or of the successor trustee, upon payment of its
charges then unpaid, the trustee ceasing to act shall, subject to Section 10.4,
pay over to the successor trustee all moneys at the time held by it hereunder
and shall execute and deliver an instrument transferring to such successor
trustee all such rights, powers, duties and obligations. Upon request of any
such successor trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a prior claim upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 6.6.

     If a successor trustee is appointed with respect to the Securities of one
or more (but not all) Series, the Company, the predecessor Trustee and each
successor trustee with respect to the Securities of any applicable Series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any Series as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and shall add to or
change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trusts hereunder by more than one
trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such trustees co-trustees of the same trust and that
each such trustee shall be trustee of a trust or trusts under separate
indentures.

     No successor trustee with respect to any Series of Securities shall accept
appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor trustee shall be qualified under the provisions of
Section 6.8 and eligible under the provisions of Section 6.9.

     Upon acceptance of appointment by any successor trustee as provided in this
Section 6.11, the Company shall give notice in the manner and to the extent
provided in Section 11.4 to the Holders of Securities of any Series for which
such successor trustee is acting as trustee at their last addresses as they
shall appear in the Security register. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
6.10. If the Company fails to mail such notice within ten days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

                                       53
<Page>

     SECTION 6.12   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS
OF TRUSTEE. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that
such corporation shall be qualified under the provisions of Section 6.8 and
eligible under the provisions of Section 6.9, without the execution or filing of
any paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

     In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities of any Series shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the
Securities of any Series shall not have been authenticated, any successor to the
Trustee may authenticate such Securities either in the name of any predecessor
Trustee hereunder or in the name of the successor Trustee; and in all such cases
such certificates shall have the full force which it is anywhere in the
Securities of such Series or in this Indenture provided that the certificate of
the Trustee shall have; provided, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Securities of any
Series in the name of any predecessor Trustee shall apply only to its successor
or successors by merger, conversion or consolidation.

     SECTION 6.13   PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY. If
and when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Securities), the Trustee shall be subject to the provisions of
the Trust Indenture Act regarding the collection of claims against the Company
(or any such other obligor).

                                  ARTICLE SEVEN

                         CONCERNING THE SECURITYHOLDERS

     SECTION 7.1    EVIDENCE OF ACTION TAKEN BY SECURITYHOLDERS.

          (a)  Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by a
specified percentage in principal amount of the Securityholders of any or all
Series may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such specified percentage of
Securityholders in person or by agent duly appointed in writing; and, except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee. Proof of execution
of any instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Sections 6.1 and 6.2)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Article.

          (b)  The ownership of Registered Securities shall be proved by the
Security register.

                                       54
<Page>

          (c)  The amount of Unregistered Securities held by any Person
executing any instrument or writing as a Securityholder, the numbers of such
Unregistered Securities, and the date of his holding the same may be proved by
the production of such Securities or by a certificate executed by any trust
company, bank, broker or member of a national securities exchange (wherever
situated), as depositary, if such certificate is in form satisfactory to the
Trustee, showing that at the date therein mentioned such Person had on deposit
with such depositary, or exhibited to it, the Unregistered Securities therein
described; or such facts may be proved by the certificate or affidavit of the
Person executing such instrument or writing as a Securityholder, if such
certificate or affidavit is in form satisfactory to the Trustee. The Trustee and
the Company may assume that such ownership of any Unregistered Security
continues until (i) another certificate or affidavit bearing a later date issued
in respect of the same Unregistered Security is produced, or (ii) such
Unregistered Security is produced by some other person, or (iii) such
Unregistered Security is surrendered in exchange for a Registered Security, or
(iv) such Unregistered Security has been cancelled in accordance with Section
2.12.

     SECTION 7.2    PROOF OF EXECUTION OF INSTRUMENTS. Subject to Sections 6.1
and 6.2, the execution of any instrument by a Securityholder or his agent or
proxy may be proved in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee.

     SECTION 7.3    HOLDERS TO BE TREATED AS OWNERS. The Company, the Trustee
and any agent of the Company or the Trustee may deem and treat the person in
whose name any Security shall be registered upon the Security register for such
Series as the absolute owner of such Security (whether or not such Security
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of and interest on such Security and for all other purposes; and neither the
Company nor the Trustee nor any agent of the Company or the Trustee shall be
affected by any notice to the contrary. All such payments so made to any such
person, or upon his order, shall be valid, and, to the extent of the sum or sums
so paid, effectual to satisfy and discharge the liability for moneys payable
upon any such Security.

     SECTION 7.4    SECURITIES OWNED BY COMPANY DEEMED NOT OUTSTANDING. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all Series have concurred in any direction,
consent or waiver under this Indenture or whether a quorum is present at a
meeting of Holders of Securities, Securities which are owned by the Company or
any other obligor on the Securities with respect to which such determination is
being made or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Securities with respect to which such determination is being made shall
be disregarded and deemed not to be Outstanding for the purpose of any such
determination, except that for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, and for
purposes of determining the presence of a quorum, only Securities which a
Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith may be
regarded as Outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Securities and that
the pledgee is not the Company or any other obligor upon the Securities or any
person directly or indirectly controlling or controlled by or under direct or

                                       55
<Page>

indirect common control with the Company or any other obligor on the Securities.
In case of a dispute as to such right, the advice of counsel shall be full
protection in respect of any decision made by the Trustee in accordance with
such advice. Upon request of the Trustee, the Company shall furnish to the
Trustee promptly an Officers' Certificate listing and identifying all
Securities, if any, known by the Company to be owned or held by or for the
account of any of the above-described persons; and, subject to Sections 6.1 and
6.2, the Trustee shall be entitled to accept such Officers' Certificate as
conclusive evidence of the facts therein set forth and of the fact that all
Securities not listed therein are Outstanding for the purpose of any such
determination.

     SECTION 7.5    RIGHT OF REVOCATION OF ACTION TAKEN. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 7.1, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any or all Series, as the case may be, specified in
this Indenture in connection with such action, any Holder of a Security the
serial number of which is shown by the evidence to be included among the serial
numbers of the Securities the Holders of which have consented to such action
may, by filing written notice at the corporate trust office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such
Security. Except as aforesaid any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon any such Security. Any action taken by the Holders of the
percentage in aggregate principal amount of the Securities of any or all Series,
as the case may be, specified in this Indenture in connection with such action
shall be conclusively binding upon the Company, the Trustee and the Holders of
all the Securities affected by such action.

     SECTION 7.6    RECORD DATE FOR DETERMINATION OF HOLDERS ENTITLED TO VOTE.
The Company may, in the circumstances permitted by the Trust Indenture Act, set
a record date for the purpose of determining the Securityholders entitled to
give or take any request, demand, authorization, direction, notice, consent,
waiver or other action, or to vote on any action, authorized or permitted to be
given or taken by Securityholders. If not set by the Company prior to the first
solicitation of a Securityholder made by any Person in respect of any such
action, or, in the case of any such vote, prior to such vote, the record date
for any such action or vote shall be the 30th day (or, if later, the date of the
most recent list of Holders required to be provided pursuant to Section 4.1)
prior to such first solicitation or vote, as the case may be. With regard to any
record date, only the Holders on such date (or their duly appointed proxies)
shall be entitled to give or take, or vote on, the relevant action.

                             SUPPLEMENTAL INDENTURES

     SECTION 8.1    SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF SECURITYHOLDERS.
The Company and, if applicable, any Guarantor, when authorized by a
resolution of their Boards of Directors, and the Trustee for the Securities
of any and all Series may from time to time and at any time enter into an
indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act of 1939 as in force at the date of the
execution thereof), in form satisfactory to such Trustee, for one or more of
the following purposes:

                                       56
<Page>

          (a)  to convey, transfer, assign, mortgage or pledge to the Trustee as
     security for the Securities of one or more Series any property or assets;

          (b)  to evidence the succession of another corporation to the Company,
     or successive successions, and the assumption by the successor corporation
     of the covenants, agreements and obligations of the Company pursuant to
     Article Nine;

          (c)  to add to the covenants of the Company such further covenants,
     restrictions, conditions or provisions as its Board of Directors and the
     Trustee shall consider to be for the protection of the Holders of
     Securities of any or all Series and, if such additional covenants are to be
     for the benefit of less than all the Series of Securities stating that such
     covenants are being added solely for the benefit of such Series, and to
     make the occurrence, or the occurrence and continuance, of a default in any
     such additional covenants, restrictions, conditions or provisions an Event
     of Default permitting the enforcement of all or any of the several remedies
     provided in this Indenture as herein set forth (and if such additional
     Events of Default are to be for the benefit of less than all Series of the
     Securities stating that such Events of Default are being added solely for
     the benefit of such Series); provided, that in respect of any such
     additional covenant, restriction, condition or provision such supplemental
     indenture may provide for a particular period of grace after default (which
     period may be shorter or longer than that allowed in the case of other
     defaults) or may provide for an immediate enforcement upon such an Event of
     Default or may limit the remedies available to the Trustee upon such an
     Event of Default or may limit the right of the Holders of a majority in
     aggregate principal amount of the Securities of such Series to waive such
     an Event of Default;

          (d)  to cure any ambiguity or to correct or supplement any provision
     contained herein or in any supplemental indenture which may be defective or
     inconsistent with any other provision contained herein or in any
     supplemental indenture; or to make such other provisions in regard to
     matters or questions arising under this Indenture or under any supplemental
     indenture as the Board of Directors may deem necessary or desirable and
     which shall not materially and adversely affect the interests of the
     Holders of the Securities or the Holders of any Coupons;

          (e)  to establish the form or terms of Securities of any Series and
     the related Guaranties as permitted by Sections 2.1 and 2.3;

          (f)  to reflect the release of any Guarantor from its obligations with
     respect to its Guaranty pursuant to the terms of such Guaranty or to add a
     Guarantor in accordance with the terms of any Series of Securities; or

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

                                       57

     The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section may
be executed without the consent of the Holders of any of the Securities at the
time Outstanding, notwithstanding any of the provisions of Section 8.2.

     SECTION 8.2    SUPPLEMENTAL INDENTURES WITH CONSENT OF SECURITYHOLDERS.
With the consent (evidenced as provided in Article Seven) of the Holders of
not less than a majority in aggregate principal amount of the Securities at
the time Outstanding of each Series affected by such supplemental indenture
(treated as one class), the Company, and, if applicable, any Guarantor, when
authorized by a resolution of its Board of Directors, and the Trustee for
such Series of Securities may, from time to time and at any time, enter into
an indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act of 1939 as in force at the date of
execution thereof) for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture or of modifying in any manner the rights of the
Holders of the Securities of each such Series; provided, that no such
supplemental indenture shall (a) extend the final maturity of any Security,
or reduce the principal amount thereof or any premium thereon, or reduce the
rate or extend the time of payment of interest thereon, or reduce any amount
payable on redemption thereof, or impair or affect the right of any
Securityholder to institute suit for payment thereof or, if the Securities
provide therefor, any right of repayment at the option of the Securityholder
without the consent of the Holder of each Security so affected, or (b) reduce
the aforesaid percentage of Securities of any Series, the consent of the
Holders of which is required for any such supplemental indenture, without the
consent of the Holders of each Security so affected.

     Upon the request of the Company, accompanied by a copy of a resolution of
the Board of Directors certified by the secretary or an assistant secretary of
the Company authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee for such Series of Securities of evidence of
the consent of Securityholders as aforesaid and other documents, if any,
required by Section 7.1, the Trustee for such Series of Securities shall join
with the Company in the execution of such supplemental indenture unless such
supplemental indenture affects such Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case such Trustee may in its
discretion, but shall not be obligated to, enter into such supplemental
indenture.

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

     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Company
shall give notice in the manner and to the extent provided in Section 11.4 to
the Holders of Securities of each Series affected

                                       58
<Page>

thereby at their addresses as they shall appear on the Securities register of
the Company, setting forth in general terms the substance of such supplemental
indenture. Any failure of the Company to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

     For the purposes of this Section 8.2 only, if the Securities of any Series
are issuable upon the exercise of warrants, each holder of an unexercised and
unexpired warrant with respect to such series shall be deemed to be a Holder of
Outstanding Securities of such Series in the amount issuable upon the exercise
of such warrant. For such purposes, the ownership of any such warrant shall be
determined by the Company in a manner consistent with customary commercial
practices. The Trustee for such series shall be entitled to rely on an Officers'
Certificate as to the principal amount of Securities of such Series in respect
of which consents shall have been executed by holders of such warrants.

     SECTION 8.3    EFFECT OF SUPPLEMENTAL INDENTURE. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and be deemed to be modified and amended in accordance therewith and the
respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the Holders of Securities
of each Series and Holders of Coupons affected thereby shall thereafter be
determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and
conditions of this Indenture for any and all purposes.

     SECTION 8.4    DOCUMENTS TO BE GIVEN TO TRUSTEE. The Trustee, subject to
the provisions of Sections 6.1 and 6.2, shall receive an Officers' Certificate
and an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant to this Article Eight complies with the applicable provisions
of this Indenture.

     SECTION 8.5    NOTATION ON SECURITIES IN RESPECT OF SUPPLEMENTAL
INDENTURES. Securities of any Series (including any Coupons appertaining
thereto) authenticated and delivered after the execution of any supplemental
indenture pursuant to the provisions of this Article may bear, upon the
direction of the Company, a notation in form satisfactory to the Trustee for the
Securities of such Series as to any matter provided for by such supplemental
indenture or as to any action taken at any such meeting. If the Company or the
Trustee shall so determine, new Securities of any Series and any Coupons
appertaining thereto so modified as to conform, in the opinion of the Trustee
and the Board of Directors, to any modification of this Indenture contained in
any such supplemental indenture may be prepared by the Company, authenticated by
the Trustee and delivered in exchange for the Securities of such Series then
Outstanding and any Coupons appertaining thereto then Outstanding.

                                  ARTICLE NINE

                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

     SECTION 9.1    COMPANY MAY CONSOLIDATE, ETC., ON CERTAIN TERMS. Nothing
contained in this Indenture or in any of the Securities shall prevent any
consolidation or merger of the Company with or into any other corporation or
corporations (whether or not affiliated with the

                                       59
<Page>

Company), or successive consolidations or mergers in which the Company or its
successor or successors shall be a party or parties, or shall prevent any sale,
conveyance or lease of all or substantially all the property of the Company to
any other corporation (whether or not affiliated with the Company) authorized to
acquire and operate the same; provided, however, and the Company hereby
covenants and agrees, that upon any such consolidation, merger, sale, conveyance
or lease, other than a merger in which the Company is the continuing
corporation, the due and punctual payment of the principal of and interest on
all of the Securities, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed by the Company, shall be expressly assumed, by
supplemental indenture satisfactory in form to the Trustee, executed and
delivered to the Trustee by the corporation (if other than the Company) formed
by such consolidation, or into which the Company shall have been merged, or by
the corporation which shall have acquired or leased such property.

     SECTION 9.2    [INTENTIONALLY OMITTED].

     SECTION 9.3    SUCCESSOR CORPORATION SUBSTITUTED. In case of any such
consolidation, merger, sale or conveyance, and following such an assumption by
the successor corporation, such successor corporation shall succeed to and be
substituted for the Company, with the same effect as if it had been named
herein. Such successor corporation may cause to be signed, and may issue either
in its own name or in the name of the Company prior to such succession any or
all of the Securities issuable hereunder which theretofore shall not have been
signed by the Company and delivered to the Trustee; and, upon the order of such
successor corporation instead of the Company and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Securities and Coupons, if any, appertaining
thereto, which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All of the Securities and Coupons, if any,
appertaining thereto, so issued shall in all respects have the same legal rank
and benefit under this Indenture as the Securities and Coupons, if any,
appertaining thereto, theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Securities and Coupons, if any,
appertaining thereto, had been issued at the date of the execution hereof. In
case of any such consolidation, merger, sale, lease or conveyance such
changes in phraseology and form (but not in substance) may be made in the
Securities and Coupons, if any, appertaining thereto, thereafter to be issued
as may be appropriate.

     In the event of any such sale or conveyance (other than a conveyance by way
of lease) the Company or any successor corporation which shall theretofore have
become such in the manner described in this Article shall be discharged from all
obligations and covenants under this Indenture and the Securities and may be
liquidated and dissolved.

     SECTION 9.4    OPINION OF COUNSEL TO TRUSTEE. The Trustee, subject to the
provisions of Sections 6.1 and 6.2, shall receive an Opinion of Counsel,
prepared in accordance with Section 11.5, as conclusive evidence that any such
consolidation, merger, sale, lease or conveyance, and any such assumption, and
any such liquidation or dissolution, complies with the applicable provisions of
this Indenture.

            SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS

     SECTION 10.1   SATISFACTION AND DISCHARGE OF INDENTURE.

          (a)  If at any time (A) the Company shall have paid or caused to be
paid the principal of and interest on all the Securities of any Series and
Coupons, if any, appertaining thereto Outstanding hereunder (other than
Securities and Coupons which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 2.11) as and when the same shall
have become due and payable, or (B) the Company shall have delivered to the
Trustee for cancellation all Securities of any Series and Coupons theretofore
authenticated (other than any Securities of such Series and Coupons which have
been destroyed, lost or stolen and which shall have been replaced or paid as
provided in Section 2.11) or (c)(i) all the Securities of such Series and
Coupons not theretofore delivered to the Trustee for cancellation shall have
become due and payable, or are by their terms to become due and payable within
one year or are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, and (ii) the
Company shall have irrevocably deposited or caused to be deposited with the
Trustee as trust funds the entire amount in the currency or currency unit
required (other than moneys repaid by the Trustee or any Paying Agent to the
Company in accordance with Section 10.4) or Government Obligations maturing as
to principal and interest in such amounts and at such times as will ensure the
availability of cash sufficient, in the opinion of a firm of independent
certified public accountants, to pay at maturity or upon redemption all
Securities of such Series and Coupons (other than any Securities of such Series
and Coupons which shall have been destroyed, lost or stolen and which shall have
been replaced or paid as provided in Section 2.11) not theretofore delivered to
the Trustee for cancellation, including principal and interest due or to become
due to such date of maturity as the case may be, and if, in any such case, the
Company shall also pay or cause to be paid all other sums payable hereunder by
the Company with respect to Securities of such Series and Coupons, then this
Indenture shall cease to be of further effect with respect to Securities of such
Series and Coupons (except as to (i) rights of registration of transfer and
exchange, and the Company's right of optional redemption, (ii) substitution of
mutilated, defaced, destroyed, lost or stolen Securities and Coupons, (iii)
rights of Holders to receive payments of principal thereof and interest thereon
upon the original stated due dates therefor (but not upon acceleration) and
remaining rights of the Holders to receive mandatory sinking fund payments, if
any, (iv) the rights, obligations and immunities of the Trustee hereunder and
(v) the rights of the Securityholders of such Series as beneficiaries hereof
with respect to the property so deposited with the Trustee payable to all or any
of them), and, subject to Section 10.5, the Trustee, on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company, shall execute proper instruments acknowledging
such satisfaction of and discharging this Indenture with respect to such Series;
provided, that the rights of Holders of the Securities and Holders of Coupons to
receive amounts in respect of principal of and interest on the Securities and
Coupons held by them shall not be delayed longer than required by
then-applicable mandatory rules or policies of any securities exchange upon
which the Securities are listed. The Company agrees to reimburse the Trustee for
any costs or expenses thereafter reasonably and properly incurred and to
compensate the Trustee for any services thereafter

                                       61
<Page>

reasonably and properly rendered by the Trustee in connection with this
Indenture, the Securities of such Series and Coupons.

          (b)  In addition to the provisions of Section 10.1(a), the Company may
terminate its obligations under the Securities of any Series and this Indenture
with respect to such Series, except those obligations referred to in the
penultimate paragraph of this Section 10.1, if the Company has irrevocably
deposited or caused to be deposited with the Trustee at its Corporate Trust
Office or such other office as the Trustee may designate, under the terms of an
irrevocable trust agreement in form and substance satisfactory to the Trustee,
as trust funds in trust solely for the benefit of the Securityholders of such
Series for that purpose, (i) cash in the currency or currency unit required or,
(ii) Government Obligations maturing as to principal and interest in such
amounts and at such times as are sufficient, in the opinion of a firm of
independent certified public accountants, without consideration of any
reinvestment of such principal or interest, to pay the principal of and interest
on the outstanding Securities of such Series and Coupons to maturity or
redemption, as the case may be, provided that the Trustee shall have been
irrevocably instructed to apply such money or the proceeds of such Government
Obligations to the payment of said principal of and interest on the Outstanding
Securities and Coupons of such Series.

     Such irrevocable trust agreement shall include, among other things,
provision for (1) payment of the principal of and interest on the Securities of
such Series and Coupons when due (by redemption, sinking fund payments or
otherwise), (2) the payment of the expenses of the Trustee incurred or to be
incurred in connection with carrying out such trust provisions, (3) rights of
registration, transfer, substitution and exchange of Securities of such Series
and Coupons in accordance with the terms stated in this Indenture and (4)
continuation of the rights and obligations and immunities of the Trustee as
against the Securityholders of such Series as stated in this Indenture.

     Notwithstanding the first paragraph of this Section 10.1(b), the Company's
obligations in Sections 2.8, 2.9, 3.1, 3.2, 3.5, 5.1, 6.6, 6.10, 10.4 and 10.5
shall survive until the Securities of such Series and Coupons, if any, are no
longer Outstanding; provided, however, that the Company's obligations in Section
5.1 shall survive only with respect to Events of Default as defined in Sections
5.1(a), 5.1(b) and 5.1(c). Thereafter, the Company's obligations in Sections
6.6, 10.4 and 10.5 shall survive.

     After any such irrevocable deposit, accompanied by an Officers' Certificate
which shall state that the provisions of the first two paragraphs of this
Section 10.1(b) have been complied with, and upon delivery by the Company to the
Trustee of (i) an Opinion of Counsel to the effect that either (a) as a result
of such deposit and the related exercise of the Company's option under this
Section 10.1(b) registration will not be required under the Investment Company
Act of 1940, as amended, by the Company, the trust funds representing such
deposit or the Trustee or (b) all necessary registrations under such Act have
been effected and (ii) an Opinion of Counsel to the effect that Securityholders
of such Series will not recognize income, gain or loss for Federal income tax
purposes as a result of such deposit and discharge and will be subject to
Federal income tax on the same amount and in the same manner and at the same
time as would have been the case if such deposit and discharge had not occurred,
then the Company shall be discharged of its obligations under the Securities of
such Series and this Indenture with respect to

                                       62
<Page>

such Series except for those surviving obligations specified above, and the
Trustee upon request shall acknowledge in writing such discharge. Prior to the
delivery of such acknowledgment, the Trustee may require the Company to deliver
to it an Officer's Certificate and Opinion of Counsel, each stating that all
conditions precedent provided for herein relating to the deposit and discharge
contemplated by this provision have been complied with, and the Trustee may also
require that the Opinion of Counsel referred to in clause (i) of this paragraph
shall also state that such deposit does not violate applicable law.

     SECTION 10.2   APPLICATION BY TRUSTEE OF FUNDS DEPOSITED FOR PAYMENT OF
SECURITIES. Subject to Section 10.4, all moneys deposited with the Trustee
pursuant to Section 10.1 shall be held in trust and applied by it to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent), to the Holders of the particular Securities of
such Series and any Coupons appertaining thereto for the payment or redemption
of which such moneys have been deposited with the Trustee, of all sums due and
to become due thereon for principal and interest; but such money need not be
segregated from other funds except to the extent required by law.

     SECTION 10.3   REPAYMENT OF MONEYS HELD BY PAYING AGENT. In connection with
the satisfaction and discharge of this Indenture with respect to Securities of
any Series or Coupons, all moneys then held by any Paying Agent under the
provisions of this Indenture with respect to such Series of Securities or
Coupons shall, upon demand of the Company, be repaid to it or paid to the
Trustee and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.

     SECTION 10.4   RETURN OF UNCLAIMED MONEYS HELD BY TRUSTEE AND PAYING AGENT.
Any moneys deposited with or paid to the Trustee or any Paying Agent for the
payment of the principal of or interest on any Security of any Series or Coupons
and not applied but remaining unclaimed for two years after the date upon which
such principal or interest shall have become due and payable, shall, upon the
written request of the Company and unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property law, be
repaid to the Company by the Trustee for such Series or such Paying Agent, and
the Holder of the Security of such Series or Holders of Coupons appertaining
thereto shall, unless otherwise required by mandatory provisions of applicable
escheat or abandoned or unclaimed property laws, thereafter look only to the
Company for any payment which such Holder may be entitled to collect, and all
liability of the Trustee or any Paying Agent with respect to such moneys shall
thereupon cease.

     SECTION 10.5   REINSTATEMENT OF COMPANY'S OBLIGATIONS. If the Trustee is
unable to apply any funds or Government Obligations in accordance with Section
10.1 by reason of any legal proceeding or by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application or by reason of the Trustee's inability to convert
any such funds or Government Obligations into the currency or currency unit
required to be paid with respect to the Securities of such Series, the Company's
obligations under this Indenture and the Securities of any Series for which such
application is prohibited shall be revived and reinstated as if no deposit had
occurred pursuant to Section 10.1 until such time as the Trustee is permitted to
apply all such funds or Government Obligations in accordance with Section 10.1
or is able to convert all such funds or Government Obligations; provided,
however,

                                       63
<Page>

that if the Company has made any payment of interest on or principal of any of
such Securities or Coupons because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Securityholders of such
Securities to receive such payment from the funds or Government Obligations held
by the Trustee.

                                 ARTICLE ELEVEN

                            MISCELLANEOUS PROVISIONS

COMPANY EXEMPT FROM INDIVIDUAL LIABILITY. No recourse under or upon any
obligation, covenant or agreement contained in this Indenture, in any Security
or Coupon appertaining thereto, or because of any indebtedness evidenced
thereby, shall be had against any incorporator, as such or against any past,
present or future stockholder, officer or director, as such, of the Company or
of any successor, either directly or through the Company or any successor, under
any rule of law, statute or constitutional provision or by the enforcement of
any assessment or by any legal or equitable proceeding or otherwise, all such
liability being expressly waived and released by the acceptance of the
Securities and Coupons, if any, by the Holders thereof and as part of the
consideration for the issue of the Securities.

     SECTION 11.2   PROVISIONS OF INDENTURE FOR THE SOLE BENEFIT OF PARTIES AND
SECURITYHOLDERS. Nothing in this Indenture or in the Securities or Coupons,
expressed or implied, shall give or be construed to give to any Person, firm or
corporation, other than the parties hereto, any Paying Agent and their
successors hereunder and the Holders of the Securities and Coupons, if any, any
legal or equitable right, remedy or claim under this Indenture or under any
covenant or provision herein contained, all such covenants and provisions being
for the sole benefit of the parties hereto and their successors and of the
Holders of the Securities and Coupons.

     SECTION 11.3   SUCCESSORS AND ASSIGNS OF COMPANY BOUND BY INDENTURE. All
the covenants, stipulations, promises and agreements in this Indenture contained
by or on behalf of the Company shall bind its successors and assigns, whether so
expressed or not.

     SECTION 11.4   NOTICES AND DEMANDS ON COMPANY, TRUSTEE AND SECURITYHOLDERS.
Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee, by the Holders of Securities, or
by the Holders of Coupons to or on the Company may be given or served by being
deposited postage prepaid, first-class mail (except as otherwise specifically
provided herein) addressed (until another address of the Company is filed by the
Company with the Trustee) to Navistar International Corporation, 4201 Winfield
Road, P.O. Box 1488, Warrenville, Illinois 60555, Attention: Secretary. Any
notice, direction, request or demand by the Company or any Securityholder to or
upon the Trustee shall be deemed to have been sufficiently given or made, for
all purposes, if given or made at the Corporate Trust Office.

     Where this Indenture provides for notice to Holders of any event, (1) if
any of the Securities affected by such event are Registered Securities, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed by first-class mail, postage prepaid to such Registered
Holders as their names and addresses appear in the Security register

                                       64
<Page>

within the time prescribed and (2) if any of the Securities affected by such
event are Unregistered Securities or Coupon Securities, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if published
once in a newspaper of general circulation in New York, New York and London,
England within the time prescribed. Where this Indenture provides for notice in
any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders, and any notice which
is mailed in the manner herein provided shall be conclusively presumed to have
been duly given.

     In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to the Company and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

     SECTION 11.5   OFFICERS' CERTIFICATES AND OPINIONS OF COUNSEL; STATEMENTS
TO BE CONTAINED THEREIN. Upon any application or demand by the Company to the
Trustee to take any action under any of the provisions of this Indenture, the
Company shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

     Each certificate or opinion provided for in this Indenture and delivered to
the Trustee with respect to compliance with a condition or covenant provided for
in this Indenture shall include (a) a statement that the person making such
certificate or opinion has read such covenant or condition, (b) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (d) a statement as to whether or not, in the opinion of such
person, such condition or covenant has been complied with.

     Any certificate, statement or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of
or representations by counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise of reasonable care should know that the same are erroneous. Any
certificate, statement or opinion of counsel may be based, insofar as it relates
to factual matters, information with respect to which is in the possession of
the Company, upon the certificate, statement or opinion of or representations by
an officer or officers of the Company, unless such counsel knows that the
certificate, statement or opinion or representations with respect to the matters

                                       65
<Page>

upon which his certificate, statement or opinion may be based as aforesaid are
erroneous, or in the exercise of reasonable care should know that the same are
erroneous.

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

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

     SECTION 11.6   PAYMENTS DUE ON SATURDAYS, SUNDAYS AND HOLIDAYS. If the date
of maturity of interest on or principal of the Securities of any Series or
Coupons appertaining thereto or the date fixed for redemption or repayment of
any such Security or Coupon shall not be a Business Day, then payment of
interest, premium, if any, or principal need not be made on such date, but may
be made on the next succeeding Business Day with the same force and effect as if
made on the date of maturity or the date fixed for redemption, and no interest
shall accrue for the period after such date.

     SECTION 11.7    CONFLICT OF ANY PROVISION OF INDENTURE WITH TRUST INDENTURE
ACT OF 1939. If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with another provision included in this Indenture which
is required to be included herein by any of Sections 310 to 317, inclusive, of
the Trust Indenture Act of 1939, such required provision shall control.

     SECTION 11.8   NEW YORK LAW TO GOVERN. This Indenture and each Security
shall be deemed to be a contract under the laws of the State of New York, and
for all purposes shall be construed in accordance with the laws of such State.

     SECTION 11.9   COUNTERPARTS. This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

     SECTION 11.10  EFFECT OF HEADINGS. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

     SECTION 11.11  DETERMINATION OF PRINCIPAL AMOUNT. In determining whether
the Holders of the requisite principal amount of outstanding Securities of any
Series have given any request, demand, authorization, direction, notice, consent
or waiver hereunder, whether a quorum is present at a meeting of Holders of
Securities or whether sufficient funds are available for redemption or for any
other purpose, the principal amount of an Original Issue Discount Security that
shall be deemed to be outstanding for such purposes shall be the amount of the
principal thereof that would be due and payable as of the date of such
determination upon a declaration of acceleration of the maturity thereof
pursuant to Section 5.1 and the principal amount of any Securities denominated
in a Foreign Currency or Euro that shall be deemed to be outstanding for

                                       66
<Page>

such purposes shall be determined by converting the Foreign Currency or the
Specified Amount of each Component Currency into Dollars at the Market Exchange
Rate as of the date of such determination.

                                 ARTICLE TWELVE

                   REDEMPTION OF SECURITIES AND SINKING FUNDS

     SECTION 12.1   APPLICABILITY OF ARTICLE. The provisions of this Article
shall be applicable to the Securities of any Series which are redeemable before
their maturity or to any sinking fund for the retirement of Securities of a
Series except as otherwise specified as contemplated by Section 2.5 for
Securities of such Series.

     SECTION 12.2   NOTICE OF REDEMPTION; PARTIAL REDEMPTIONS. Notice of
redemption to the Holders of Securities of any Series to be redeemed as a whole
or in part at the option of the Company shall be given by giving notice of such
redemption as provided in Section 11.4, at least 30 days and not more than 60
days prior to the date fixed for redemption to such Holders of Securities of
such Series. Failure to give notice by mail, or any defect in the notice to the
Holder of any Security of a Series designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Security of such Series.

     The notice of redemption to each such Holder shall identify the Securities
to be redeemed (including "CUSIP" or "ISIN" numbers), specify the date fixed for
redemption, the redemption price, the Place or Places of Payment, that payment
will be made upon presentation and surrender of such Securities, and that,
unless otherwise specified in such notice, Coupon Securities, if any,
surrendered for payment must be accompanied by all Coupons maturing subsequent
to the redemption date, failing which the amount of any such missing Coupon or
Coupons will be deducted from the sum due for payment, that such redemption is
pursuant to the mandatory or optional sinking fund, or both, if such be the
case, that interest accrued to the date fixed for redemption will be paid as
specified in such notice and that on and after said date interest thereon or on
the portions thereof to be redeemed will cease to accrue and that, if less than
all of the Outstanding Securities of a Series are to be redeemed, the
identification and principal amount of the Securities to be redeemed. If less
than all of the Securities of any Series and to be redeemed, the notice of
redemption shall specify the numbers of the Securities of such Series to be
redeemed, and, if only Unregistered Securities of any Series are to be redeemed,
and if such Unregistered Securities may be exchanged for Registered Securities,
the last date on which exchanges of Unregistered Securities for Registered
Securities not subject to redemption may be made. In case any Security of a
Series is to be redeemed in part, the notice of redemption shall state the
portion of the principal amount thereof to be redeemed and shall state that on
and after the date fixed for redemption, upon surrender of such Security and any
Coupons appertaining thereto, a new Security or Securities of such Series in
principal amount equal to the unredeemed portion thereof with appropriate
Coupons will be issued.

     The notice of redemption of Securities of any Series to be redeemed at the
option 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. The
Company shall give the Trustee at least 45 days prior written notice of any
redemption hereunder.

                                       67
<Page>

     Not later than 9:00 a.m., Chicago time, on the redemption date specified in
the notice of redemption given as provided in this Section, the Company will
have on deposit with the Trustee or with one or more paying agents (or, if the
Company is acting as its own paying agent, set aside, segregate and hold in
trust as provided in Section 3.4) an amount of money in the currency or currency
unit in which the Securities of such Series and any Coupons appertaining thereto
are payable (except as otherwise specified pursuant to Section 2.5 and except as
provided in Sections 2.12(b), (e) and (f) of this Indenture) sufficient to
redeem on the redemption date all the Securities of such Series so called for
redemption at the appropriate redemption price, together with accrued interest
to the date fixed for redemption. If less than all the Outstanding Securities of
a Series are to be redeemed, the Company will deliver to the Trustee at least 60
days prior to the date fixed for redemption an Officers' Certificate stating the
aggregate principal amount of Securities to be redeemed.

     If less than all the Securities of a Series are to be redeemed, the Trustee
shall select, in such manner as it shall deem appropriate and fair, Securities
of such Series to be redeemed in whole or in part. Securities may be redeemed in
part in multiples equal to the minimum authorized denomination for Securities of
such Series or any multiple thereof. The Trustee shall promptly notify the
Company in writing of the Securities of such Series selected for redemption and,
in the case of any Securities of such Series 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 of any Series shall relate, in the case of any Security redeemed
or to be redeemed only in part, to the portion of the principal amount of such
Security which has been or is to be redeemed.

     SECTION 12.3   PAYMENT OF SECURITIES CALLED FOR REDEMPTION. If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Company shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 6.5 and 10.4, such Securities shall
cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof shall have no right in
respect of such Securities except the right to receive the redemption price
thereof and unpaid interest to the date fixed for redemption. On presentation
and surrender of such Securities at a place of payment specified in said notice,
said Securities or the specified portions thereof shall be paid and redeemed by
the Company at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption; provided that any semiannual payment
of interest on Registered Securities becoming due on the date fixed for
redemption shall be payable to the Holders of such Securities registered as such
on the relevant record date subject to the terms and provisions of Section 2.6
hereof.

     If any Coupon Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing on or after the date fixed for redemption,
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

                                       68
<Page>

require to save each of them and any Paying Agent harmless. If thereafter the
Holder of such Security shall surrender to any Paying Agent any 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, unless otherwise provided pursuant to Section 2.5, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an office or agency located outside of the United States.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid or duly provided for,
bear interest from the date fixed for redemption at the rate of interest borne
by the Security.

     Upon presentation of any Security redeemed in part only and the Coupons
appertaining thereto, the Company shall execute and the Trustee shall
authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, a new Security or Securities and the Coupons
appertaining thereto, of authorized denominations, in principal amount equal to
the unredeemed portion of the Security so presented.

     SECTION 12.4   EXCLUSION OF CERTAIN SECURITIES FROM ELIGIBILITY FOR
SELECTION FOR REDEMPTION. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in a written statement signed by an authorized officer of the Company and
delivered to the Trustee at least 40 days prior to the last date on which notice
of redemption may be given as being owned of record and beneficially by, and not
pledged or hypothecated by, either (a) the Company or (b) an entity specifically
identified in such written statement directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company.

     SECTION 12.5   MANDATORY AND OPTIONAL SINKING FUNDS. The minimum amount of
any sinking fund payment provided for by the terms of Securities of any Series
is herein referred to as a "mandatory sinking fund payment", and any payment in
excess of such minimum amount provided for by the terms of Securities of any
Series is herein referred to as an "optional sinking fund payment". The date on
which a sinking fund payment is to be made is herein referred to as the "sinking
fund payment date".

     In lieu of making all or any part of any mandatory sinking fund payment
with respect to any Series of Securities in cash, the Company may at its option
(a) deliver to the Trustee Securities of such Series (together with the
unmatured Coupons, if any, appertaining thereto) theretofore purchased or
otherwise acquired (except upon redemption pursuant to the mandatory sinking
fund) by the Company or receive credit for Securities of such Series (not
previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Company and delivered to the Trustee for cancellation pursuant
to Section 2.12, (b) receive credit for optional sinking fund payments (not
previously so credited) made pursuant to this Section, or (c) receive credit for
Securities of such Series (not previously so credited) redeemed by the Company
through any optional redemption provision contained in the terms of such Series.
Securities so delivered or credited shall be received or credited by the Trustee
at the sinking fund redemption price specified in such Securities.

                                       69
<Page>

     On or before the sixtieth day next preceding each sinking fund payment date
for any Series of Securities, the Company will deliver to the Trustee a written
statement (which need not contain the statements required by Section 11.5)
signed by an authorized officer of the Company (a) specifying the portion of the
mandatory sinking fund payment to be satisfied by payment of cash in the
currency or currency unit in which the Securities of such Series and Coupons, if
any, appertaining thereto are payable (except as otherwise specified pursuant to
Section 2.5 for the Securities of such Series and except as provided in Section
2.14(b), (e) and (f) hereof), and the portion to be satisfied by credit of
Securities of such Series, (b) stating that none of the Securities of such
Series has theretofore been so credited, (c) stating that no defaults in the
payment of interest or Events of Default with respect to such Series have
occurred (which have not been waived or cured) and are continuing, (d) stating
whether or not the Company intends to exercise its right to make an optional
sinking fund payment with respect to such Series and, if so, specifying the
amount of such optional sinking fund payment which the Company intends to pay on
or before the next succeeding sinking fund payment date and (e) specifying such
sinking fund payment date. Any Securities of such Series to be credited and
required to be delivered to the Trustee in order for the Company to be entitled
to credit therefor as aforesaid which have not theretofore been delivered to the
Trustee shall be delivered for cancellation pursuant to Section 2.12 to the
Trustee with such written statement (or reasonably promptly thereafter if
acceptable to the Trustee). Such written statement shall be irrevocable and upon
its receipt by the Trustee the Company shall become unconditionally obligated to
make all the cash payments or payments therein referred to, if any, on or before
the next succeeding sinking fund payment date. Failure of the Company, on or
before any such sixtieth day, to deliver such written statement and Securities
specified in this paragraph, if any, shall not constitute a default but shall
constitute, on and as of such date, the irrevocable election of the Company (i)
that the mandatory sinking fund payment for such Series due on the next
succeeding sinking fund payment date shall be paid entirely in cash (in the
currency or currency unit described above) without the option to deliver or
credit Securities of such Series in respect thereof and (ii) that the Company
will make no optional sinking fund payment with respect to such Series as
provided in this Section.

     If the sinking fund payment or payments (mandatory or optional or both) to
be made in cash (in the currency or currency unit described above) on the next
succeeding sinking fund payment date plus any unused balance of any preceding
sinking fund payments made in cash shall exceed $100,000, or the equivalent in
the currency or currency unit in which the Securities of such Series are payable
(or a lesser sum if the Company shall so request) with respect to the Securities
of any particular Series, such cash shall be applied on the next succeeding
sinking fund payment date to the redemption of Securities of such Series at the
sinking fund redemption price together with accrued interest to the date fixed
for redemption. If such amount shall be $100,000, or the equivalent in the
currency or currency unit in which the Securities of such Series are payable, or
less and the Company makes no such request then it shall be carried over until a
sum in excess of $100,000, or the equivalent in the currency or currency unit in
which the Securities of such Series are payable, is available. The Trustee shall
select, in the manner provided in Section 12.2, for redemption on such sinking
fund payment date a sufficient principal amount of Securities of such Series to
absorb said cash, as nearly as may be possible, and shall (if requested in
writing by the Company) inform the Company of the serial numbers of the
Securities of such Series (or portions thereof) so selected. Securities of any
Series which are identified by registration and certificate number in an
Officers' Certificate at least 60 days prior to the sinking fund payment date as
being beneficially owned by, and not pledged or

                                       70
<Page>

hypothecated by, the Company or an entity directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company shall
be excluded from Securities of such Series eligible for selection for
redemption. The Trustee, in the name and at the expense of the Company (or the
Company, if it shall so notify the Trustee in writing) shall cause notice of
redemption of the Securities of such Series to be given in substantially the
manner provided in Section 12.2 (and with the effect provided in Section 12.3)
for the redemption of Securities of such Series in part at the option of the
Company. The amount of any sinking fund payments not so applied or allocated to
the redemption of Securities of such Series shall be added to the next cash
sinking fund payment for such Series and, together with such payment, shall be
applied in accordance with the provisions of this Section. Any and all sinking
fund moneys held on the stated maturity date of the Securities of any particular
Series (or earlier, if such maturity is accelerated), which are not held for the
payment or redemption of particular Securities of such Series shall be applied,
together with other moneys, if necessary, sufficient for the purpose, to the
payment of the principal of, and interest on, the Securities of such Series at
maturity.

     The Trustee shall not convert any currency or currency unit in which the
Securities of such Series are payable for the purposes of such sinking fund
application unless specifically requested to do so by the Company, and any such
conversion agreed to by the Trustee in response to such request shall be for the
account and at the expense of the Company and shall not affect the Company's
obligation to pay the Holders in the currency or currency unit to which such
Holder may be entitled.

     Not later than 9:00 a.m., Chicago time, on the sinking fund payment date,
the Company shall have paid to the Trustee in cash (in the currency or currency
unit described in the third paragraph of this Section 12.5) or shall otherwise
provide for the payment of all interest accrued to the date fixed for redemption
on Securities to be redeemed on the next following sinking fund payment date.

     The Trustee shall not redeem or cause to be redeemed any Securities of a
Series with sinking fund moneys or mail or publish any notice of redemption of
Securities for such Series by operation of the sinking fund during the
continuance of a default in payment of interest on such Securities or of any
Event of Default except that, where the mailing or publication of notice of
redemption of any Securities shall theretofore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, provided that it shall have
received from the Company a sum sufficient for such redemption. Except as
aforesaid, any moneys in the sinking fund for such Series at the time when any
such default or Event of Default shall occur, and any moneys thereafter paid
into the sinking fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and held for the
payment of all such Securities. In case such Event of Default shall have been
waived as provided in Section 5.10 or the default cured on or before the
sixtieth day preceding the sinking fund payment date in any year, such moneys
shall thereafter be applied on the next succeeding sinking fund payment date in
accordance with this Section to the redemption of such Securities.

     SECTION 12.6   REPAYMENT AT THE OPTION OF THE HOLDERS. 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.

                                       71
<Page>

     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 10.1, 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.

                                ARTICLE THIRTEEN

                                   GUARANTIES

     SECTION 13.1   GUARANTY.

     Subject to this Article Thirteen, if the Securities of any Series provide
for a Guaranty, any such Guarantor hereby guarantees to each Holder of a
Security authenticated and delivered by the Trustee and to the Trustee and its
successors and assigns, irrespective of the validity and enforceability of this
Indenture, the Securities or the obligations of the Company hereunder or
thereunder, that: (a) the principal of and interest on the Securities will be
promptly paid in full when due, whether at maturity, by acceleration, redemption
or otherwise, and interest on the overdue principal of and interest on the
Securities, if any, if lawful, and all other obligations of the Company to the
Holders or the Trustee hereunder or thereunder will be promptly paid in full or
performed, all in accordance with the terms hereof and thereof; and (b) in case
of any extension of time of payment or renewal of any Securities or any of such
other obligations, that same will be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed or any performance so guaranteed for whatever reason, such
Guarantor shall be obligated to pay the same immediately. Each Guarantor agrees
that this is a guarantee of payment and not a guarantee of collection.

     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 of Securities 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 this Guaranty shall 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, the Guarantor or any custodian, trustee, liquidator or
other similar official acting in relation to either the Company or a Guarantor,
any amount paid by either to the Trustee or such Holder, this Guaranty, to the
extent theretofore discharged, shall be reinstated in full force and effect.

                                       72
<Page>

     Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between such 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 Five
hereof for the purposes of this Guaranty, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of
the obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such obligations as provided in Article Five hereof, such
obligations (whether or not due and payable) shall forthwith become due and
payable by the Guarantor for the purpose of this Guaranty. Each Guarantor
shall have the right to seek contribution from any non-paying Guarantor so
long as the exercise of such right does not impair the rights of the Holders
under the Guaranty.

     SECTION 13.2   SUBORDINATION OF GUARANTY.

     The Obligations of a Guarantor under its Guaranty pursuant to this Article
Thirteen shall be junior and subordinated to the senior debt of the Guarantor.
For the purposes of the foregoing sentence, the Trustee and the Holders shall
have the right to receive and/or retain payments by a Guarantor only at such
times as they may receive and/or retain payments in respect of the Securities
pursuant to this Indenture, including Article Thirteen hereof.

     SECTION 13.3   LIMITATION ON GUARANTOR LIABILITY.

     Each Guarantor, and by its acceptance of Securities, each Holder, hereby
confirms that it is the intention of all such parties that the Guaranty not
constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law,
the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or
any similar federal or state law to the extent applicable to any Guaranty. To
effectuate the foregoing intention, the Trustee, the Holders and each Guarantor
hereby irrevocably agree that the obligations of such Guarantor under its
Guaranty and this Article Thirteen shall be limited to the maximum amount as
will, after giving effect to such maximum amount and all other contingent and
fixed liabilities of the Guarantor that are relevant under such laws, result in
the obligations of such Guarantor under its Guaranty not constituting a
fraudulent transfer or conveyance.

     SECTION 13.4   EXECUTION AND DELIVERY OF GUARANTY.

     To evidence the Guaranty set forth in Section 13.1, each Guarantor
hereby agrees that a notation of such Guaranty in substantially the form

                                HOLDERS' MEETINGS

     SECTION 14.1   PURPOSES OF MEETINGS. A meeting of Holders of Securities of
any or all Series may be called at any time and from time to time pursuant to
the provisions of this Article Fourteen for any of the following purposes:

          (a)  to give any notice to the Company or to the Trustee for the
     Securities of such Series, or to give any directions to the Trustee for
     such Series, or to consent to the waiving of any default hereunder and its
     consequences, or to take any other action authorized to be taken by Holders
     pursuant to any of the provisions of Article Five;

          (b)  to remove the Trustee for such Series and nominate a successor
     Trustee pursuant to the provisions of Article Six;

          (c)  to consent to the execution of an indenture or indentures
     supplemental hereto pursuant to the provisions of Section 8.2; and

          (d)  to take any other action authorized to be taken by or on behalf
     of the Holders of any specified aggregate principal amount of the
     Securities of any one or more or all Series, as the case may be, under any
     provision of this Indenture or under applicable law.

     SECTION 14.2   CALL OF MEETINGS BY TRUSTEE. The Trustee for the Securities
of any Series may at any time call a meeting of Holders of Securities of such
Series to take any action specified in Section 14.1, to be held at such time and
at such place in the City of [_____], or such other Place of Payment as the
Trustee for such Series shall determine. Notice of every meeting of the Holders

more than 90 days prior to the date fixed for the meeting.

     SECTION 14.3   CALL OF MEETINGS BY COMPANY OR HOLDERS. In case at any time
the Company, pursuant to a resolution of its Board of Directors, or the Holders
of at least 10% in aggregate principal amount of the Outstanding Securities of

Series to call a meeting of Holders of Securities of any or all Series, as the
case may be, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee for such Series shall not
have given the notice of such meeting within 20 days after receipt of such
request, then the Company or such Holders may determine the time and the place
in the City of Chicago or such other Place of Payment for such meeting and may
call such meeting to take any action authorized in Section 14.1, by giving
notice thereof as provided in Section 14.2.

                                       74

     SECTION 14.4   QUALIFICATIONS FOR VOTING. To be entitled to vote at any
meeting of Holders, a person shall be (a) a Holder of one or more Securities
with respect to which such meeting is being held or (b) a person appointed by an
instrument in writing as proxy by such Holder. The only persons who shall be
entitled to be present or to speak at any meeting of Holders shall be the
persons entitled to vote at such meeting and their counsel and any
representatives of the Trustee for the Securities of the Series with respect to
which such meeting is being held and its counsel and any representatives of the
Company and its counsel.

     SECTION 14.5   REGULATIONS. Notwithstanding any other provisions of this
Indenture, the Trustee for the Securities of any Series may make such reasonable
regulations as it may deem advisable for any meeting of Holders of the
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 think fit.

     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 the Securities of such Series as provided in Section
14.3, in which case the Company or the Holders calling the meeting, as the case
may be, shall in like manner appoint a temporary chairman. A permanent chairman
and a permanent secretary of the meeting shall be elected by majority vote of
the meeting.

     Subject to Section 7.4, at any meeting each Holder of Securities with
respect to which such meeting is being held or proxy therefor shall be entitled
to one vote for each $1,000 (or the equivalent in the currency or currency unit
in which such Securities are denominated, as determined pursuant to Section
11.11) principal amount (in the case of the Original Issue Discount Securities,
such principal amount to be determined as provided in Section 11.11) of
Securities held or represented by him. However, no vote shall be cast or counted
at any meeting in respect of any such 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 other than by virtue of the Securities of
such Series held by him or instruments in writing aforesaid duly designating him
as the person to vote on behalf of other Holders of such Series. At any meeting
of Holders, the presence of persons holding or representing Securities with
respect to which such meeting is being held in an aggregate principal amount
sufficient to take action on the business for the transaction of which such
meeting was called shall constitute a quorum, but, if less than a quorum is
present, the persons holding or representing a majority in aggregate principal
amount of such Securities represented at the meeting may adjourn such meeting
with the same effect, for all intents and purposes, as though a quorum had been
present. Any meeting of Holders of Securities with respect to which a meeting
was duly called pursuant to the provisions of Section 14.2 or Section 14.3 may
be adjourned from time to time by a majority of such Holders present, whether or
not constituting a quorum, and the meeting may be held as so adjourned without
further notice.

     SECTION 14.6   VOTING. The vote upon any resolution submitted to any
meeting of Holders of Securities with respect to which such meeting is being
held shall be by written ballots on which shall be subscribed the signatures of
such Holders or of their representatives by proxy

                                       75
<Page>

and the serial number or numbers of the Securities 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 duplicate of all votes cast at the meeting. A record in duplicate of
the proceedings of each meeting of Holders shall be prepared by the secretary of
the meeting and there shall be attached to such 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 such notice was given in the manner and
to the extent provided in Section 11.4. The record shall show the serial numbers
of the Securities voting in favor of or against any resolution. The record shall
be signed and verified by the affidavits of the permanent chairman and secretary
of the meeting and one of the duplicates shall be delivered to the Company and
the other to the Trustee to be preserved by the Trustee.

     Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

     SECTION 14.7   NO DELAY OF RIGHTS BY MEETING. Nothing in this Article
Fourteen shall be deemed or construed to authorize or permit, by reason of any
call of a meeting of Holders or any rights expressly or impliedly conferred
hereunder to make such call, any hindrance or delay in the exercise of any right
or rights conferred upon or reserved to the Trustee or to the Holders under any
of the provisions of this Indenture or of the Securities of any Series.
