Notes, as the case may be, to instruct the Book-Entry Depositary as to the
consent, waiver or other action, if any, pertaining to the Certificateless
Depositary Interests or Global Notes, as the case may be, and (c) a statement as
to the manner in which such instructions may be given. Upon the written request
of the Depositary received on or before the date established by the Issuer for
such purpose, the Book-Entry Depositary shall, or if applicable, shall cause the
Note Custodian to, endeavor insofar as practicable and permitted under the
provisions governing the Certificateless Depositary Interests or Global Notes,
as the case may be, to take such action regarding the requested consent, waiver
or other action in respect of such Certificateless Depositary Interest or Global
Note, as the case may be, in accordance with any instructions set forth in such
request. The Book-Entry Depositary and the Note Custodian shall not themselves
exercise any discretion in the granting of consents or waivers or the taking of
any other action in respect of the Certificateless Depositary Interests, the
Book-Entry Interests or Global Notes.

SECTION 2.13    CHANGES AFFECTING THE GLOBAL NOTES.

               Upon any reclassification of the Global Notes or upon any merger
or consolidation or sale of substantially all the assets affecting the Issuer or
to which the Issuer is a party, any securities that shall be received by the
Book-Entry Depositary or the Note Custodian in exchange for or in respect of a
Global Note shall be treated as a new Global Note or as part of the Global Note
under this Agreement and any corresponding Certificateless Depositary Interest
shall thenceforth represent such Global Note, including such new securities so
received.

SECTION 2.14    REPORTS.

               The Book-Entry Depositary and the Note Custodian will as soon as
practicable (and in no event later than 10 days from receipt) send to the
Depositaries a copy of any notices, reports and other communications received
relating to the Issuer, the Global Notes or the Book-Entry Interests.

SECTION 2.15    ADDITIONAL AMOUNTS.

               At least 10 days prior to the first date on which payment of
principal, premium, if any, or interest on the Notes is to be made, and at least
10 days prior to any subsequent such date if there has been any change with
respect to the matters set forth in the Officers' Certificate described in
Section 4.20 of the Indenture, the Issuer will furnish the Book-Entry Depositary
with an Officers' Certificate specifying whether such payment of principal,
premium, if any, or interest on the Notes shall be made without withholding or
deduction for, or on account of, any Taxes and the amount, if any, required to
be withheld on such payments and the amount, if any, of additional amounts
payable, net of amounts to which the Depositary or owner of Book-Entry Interests
is not entitled. The Book-Entry Depositary shall have no responsibility for
determining whether the Depositary or any owner of a Book-Entry Interest is
entitled to the payment of Additional Amounts, but shall be entitled to rely
conclusively for this purpose on the Officers' Certificate or on certifications
from the Depositary. The Issuer shall, prior to the date on which the Book-Entry
Depositary is required to make such payment, pay to the Book-Entry Depositary
amounts equal to any Additional Amounts payable on such date by the Book-Entry
Depositary under this Agreement. The Issuer shall indemnify the Book-Entry
Depositary for, and hold it 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 it in reliance on any
Officers' Certificate furnished to them pursuant to this Section 2.15 or failure
to furnish any such Officers' Certificate. Notwithstanding anything to the
contrary provided above, the Book-Entry Depositary shall pay or cause to be paid
Additional Amounts only out of funds that shall be received by it from the
Issuer for that purpose.

of the aforesaid supervising or examining authority, then for the purposes of
this Section 3.05, 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. If at any time the Book-Entry Depositary or
the Note Custodian shall cease to be eligible in accordance with the provisions

or the successor Note Custodian, as the case may be, in accordance with the
applicable requirements of Section 3.07 hereof or (ii) the issuance of
Definitive Notes in accordance with Sections 2.05 and 2.08 hereof.

and the Depositary and the Trustee, in accordance with Section 4.01 and Section
4.02 hereof, 60 days prior to the effective date of such resignation. The
Book-Entry Depositary or the Note Custodian may be removed at

                                       13
<Page>

any time upon 90 days' notice by the filing with it and the Trustee of an
instrument in writing signed on behalf of the Issuer and specifying such removal
and the date when it is intended to become effective. If the instrument of
acceptance by a successor Book-Entry Depositary required by Section 3.08 hereof
shall not have been delivered to the Book-Entry Depositary within 30 days after
the giving of such notice of resignation, the resigning Book-Entry Depositary or
the resigning Note Custodian may petition any court of competent jurisdiction
for the appointment of a successor Book-Entry Depositary or a successor Note
Custodian, as applicable. If, at the end of 90 days after the delivery of such
notice, no successor depositary has been appointed and has accepted such
appointment, the Book-Entry Depositary may terminate this Agreement.

     incapable of acting with respect to the Certificateless Depositary
     Interests or shall be adjudged a bankrupt or insolvent, or a receiver or
     liquidator of the Book-Entry Depositary or the Note Custodian or of their
     respective property shall be appointed or any public officer shall take
     charge or control of the Book-Entry Depositary or the Note Custodian or of
     their respective property or affairs for the purpose of rehabilitation,
     conservation or liquidation,

then, in any such case, (i) the Issuer, by Board Resolution, may immediately
remove the Book-Entry Depositary or the Note Custodian and appoint a successor
Book-Entry Depositary or a successor Note Custodian or (ii) the Depositary, the
Book-Entry Depositary or the Note Custodian may, on behalf of itself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Book-Entry Depositary or the Note Custodian and the appointment
of a successor Book-Entry Depositary or a successor Note Custodian unless the
Definitive Notes have been issued in accordance with the Indenture. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Book-Entry Depositary or the Note Custodian and appoint a successor
Book-Entry Depositary or a successor Note Custodian.

               (d)  If the Book-Entry Depositary or the Note Custodian shall
resign, be removed or become incapable of acting, or if a vacancy shall occur in

requirements of Section 3.07 hereof. If no successor Book-Entry Depositary or
successor Note Custodian with respect to the Global Notes shall have been so
appointed by the Issuer and accepted appointment in the manner required by

situated, petition any court of competent jurisdiction for the appointment of a
successor Book-Entry Depositary or a successor Note Custodian unless Definitive
Notes have been issued in accordance with the Indenture.

               (e)  The Issuer shall give, or shall cause such successor
Book-Entry Depositary or successor Note Custodian to give, notice of each
resignation and each removal of a Book-Entry Depositary or a Note Custodian and
each appointment of a successor Book-Entry Depositary or a successor Note
Custodian to the applicable Holder in accordance with Section 4.02 hereof. Each

successor Note Custodian, as the case may be, and the address of its corporate
trust office.

SECTION 3.07    ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

               (a)  In case of the appointment hereunder of a successor
Book-Entry Depositary or a successor Note Custodian, every such successor
Book-Entry Depositary or successor Note Custodian so appointed shall execute,
acknowledge and deliver to the Issuer and to the retiring Book-Entry Depositary
or the retiring Note Custodian an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Book-Entry Depositary or
the retiring Note Custodian shall become effective and such successor Book-Entry
Depositary or such successor Note Custodian, without any further act, deed or
conveyance, shall become vested with all the rights, powers, agencies and duties
of the retiring Book-Entry Depositary or the retiring Note Custodian, with like
effect as if originally named as the Book-Entry Depositary hereunder or the Note
Custodian hereunder but, on the request of the Issuer or a successor Book-Entry
Depositary or a successor Note Custodian, the retiring Book-Entry Depositary or
the retiring Note Custodian shall, upon payment of all amounts due and payable
to it pursuant to Section 3.04 hereof, execute and deliver an instrument
transferring to the successor Book-Entry Depositary or the successor Note
Custodian, as the case may be, all the rights and powers of the retiring
Book-Entry Depositary or the Note Custodian and shall duly assign, transfer and
deliver to the successor Book-Entry Depositary or the successor Note Custodian
all property and money held by the retiring Book-Entry Depositary hereunder or
the retiring Note Custodian hereunder and shall deliver the Global Notes to the
successor.

               (b)  Upon request of any such successor Book-entry Depositary or
the successor Note Custodian, the Issuer shall execute any and all instruments
for more fully and certainly vesting in and confirming to the successor

such rights, powers and agencies referred to in paragraph (a) of this Section
3.07.

               (c)  No successor Book-Entry Depositary or successor Note
Custodian shall accept its appointment unless at the time of such acceptance

eligible under this Article Three.

Depositary or successor Note Custodian as provided in this Section 3.07, the
Issuer shall give notice thereof to the Depositary in accordance with Section
4.02 hereof. If the acceptance of appointment is substantially contemporaneous
with the resignation of the Book-Entry Depositary or the Note Custodian, then
the notice called for by the preceding sentence may be combined with the notice
called for the Section 3.06 hereof. If the Issuer fails to give such notice
within 15 days after acceptance of appointment by a successor Book-Entry
Depositary or a successor Note Custodian, the successor Book-Entry Depositary or
the successor Note Custodian shall promptly cause such notice to be given at the
expense of the Issuer.

then such notification as shall be made with the approval of the Book-Entry
Depositary shall constitute a sufficient notification for every purpose
hereunder.
