of the Capital Securities, and the Guarantee Trustee shall not transfer this
Guarantee to any Person except a Holder of Capital Securities exercising his or
her rights pursuant to Section 4.4(b) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, and such
vesting and cessation of title shall be effective whether or not conveyancing
documents have been executed and delivered pursuant to the appointment of such
Successor Guarantee Trustee.

(b)If an
Event of Default actually known to a Responsible Officer of the Guarantee
Trustee has occurred and is continuing, the Guarantee Trustee shall enforce this
Guarantee for the benefit of the Holders of the Capital Securities.

(c)The
Guarantee Trustee, before the occurrence of any Event of Default and after the
curing or waiving of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Guarantee, and no implied covenants shall be read into this Guarantee against
the Guarantee Trustee. In case an Event of Default has occurred (that has not
been cured or waived pursuant to Section 2.4(b)) and is actually known to a
Responsible Officer of the Guarantee Trustee, the Guarantee Trustee shall
exercise such of the rights and powers vested in it by this Guarantee, and use
the same degree of care and skill in its exercise thereof, as a prudent person
would exercise or use under the circumstances in the conduct of his or her own
affairs.

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

(i)prior to
the occurrence of any Event of Default and after the curing or waiving of all
Events of Default that may have occurred:

(A)the
duties and obligations of the Guarantee Trustee shall be determined solely by
the express provisions of this Guarantee, and the Guarantee Trustee shall not be
liable except for the performance of such duties and obligations as are
specifically set forth in this Guarantee, and no implied covenants or
obligations shall be read into this Guarantee against the Guarantee Trustee;
and

absence of bad faith on the part of the Guarantee Trustee, the Guarantee Trustee
may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon any certificates or opinions furnished to
the Guarantee Trustee and conforming to the requirements of this Guarantee; but
in the case of any such certificates or opinions furnished to the Guarantee
Trustee, the Guarantee Trustee shall be under a duty to examine the same to
determine whether or not on their face they conform to the requirements of this
Guarantee;
4

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

(iii)the
Guarantee 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 written direction
of the Holders of not less than a Majority in liquidation amount of the Capital
Securities relating to the time, method and place of conducting any proceeding
for any remedy available to the Guarantee Trustee, or exercising any trust or
power conferred upon the Guarantee Trustee under this Guarantee;
and

(iv)no
provision of this Guarantee shall require the Guarantee 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 the Guarantee Trustee shall have reasonable grounds for believing
that the repayment of such funds is not reasonably assured to it under the terms
of this Guarantee, or security and indemnity, reasonably satisfactory to the
Guarantee Trustee, against such risk or liability is not reasonably assured to
it.

SECTION
2.2.Certain
Rights of the Guarantee Trustee.

(a)Subject
to the provisions of Section 2.1:

(i)The
Guarantee Trustee may conclusively rely, and shall be fully protected in acting
or refraining from acting upon, any resolution, certificate, statement,

debenture, note, other evidence of indebtedness or other paper or document
believed by it to be genuine and to have been signed, sent or presented by the
proper party or parties.

(ii)Any
direction or act of the Guarantor contemplated by this Guarantee shall be
sufficiently evidenced by an Officer’s Certificate.

(iii)Whenever,
in the administration of this Guarantee, the Guarantee Trustee shall deem it
desirable that a matter be proved or established before taking, suffering or
omitting any action hereunder, the Guarantee Trustee (unless other evidence is
herein specifically prescribed) may, in the absence of bad faith on its part,
request and conclusively rely upon an Officer’s Certificate of the Guarantor
which, upon receipt of such request, shall be promptly delivered by the
Guarantor.

(iv)The
Guarantee Trustee shall have no duty to see to any recording, filing or
registration of any instrument or other writing (or any rerecording, refiling or
reregistration thereof).
5

(v)The

opinion of such counsel with respect to legal matters shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in accordance with such advice or opinion.
Such counsel may be counsel to the Guarantor or any of its Affiliates and may
include any of its employees. The Guarantee Trustee shall have the right at any
time to seek instructions concerning the administration of this Guarantee from
any court of competent jurisdiction.

(vi)The
Guarantee Trustee shall be under no obligation to exercise any of the rights or
powers vested in it by this Guarantee at the request or direction of any Holder,
unless such Holder shall have provided to the Guarantee Trustee such security
and indemnity, reasonably satisfactory to the Guarantee Trustee, against the
costs, expenses (including attorneys’ fees and expenses and the expenses of the
Guarantee Trustee’s agents, nominees or custodians) and liabilities that might
be incurred by it in complying with such request or direction, including such
reasonable advances as may be requested by the Guarantee Trustee;provided,however, that
nothing contained in this Section 2.2(a)(vi) shall be taken to relieve the
Guarantee Trustee, upon the occurrence of an Event of Default, of its obligation
to exercise the rights and powers vested in it by this Guarantee.

(vii)The
Guarantee 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, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document, but the Guarantee Trustee,
in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit.

(viii)The
Guarantee Trustee may execute any of the trusts or powers hereunder or perform
any duties hereunder either directly or by or through agents, nominees,
custodians or attorneys, and the Guarantee Trustee shall not be responsible for
any misconduct or negligence on the part of any agent or attorney appointed with
due care by it hereunder.

(ix)Any
action taken by the Guarantee Trustee or its agents hereunder shall bind the
Holders of the Capital Securities, and the signature of the Guarantee Trustee or
its agents alone shall be sufficient and effective to perform any such action.
No third party shall be required to inquire as to the authority of the Guarantee
Trustee to so act or as to its compliance with any of the terms and provisions
of this Guarantee, both of which shall be conclusively evidenced by the
Guarantee Trustee’s or its agent’s taking such action.

(x)Whenever
in the administration of this Guarantee the Guarantee Trustee shall deem it
desirable to receive instructions with respect to enforcing any remedy or right
or taking any other action hereunder, the Guarantee Trustee (A) may request
instructions from the Holders of a Majority in liquidation amount of the Capital
Securities, (B) may refrain from enforcing such remedy or right or taking such
other action until such instructions are received and (C) shall be protected in
conclusively relying on or acting in accordance with such
instructions.

(xi)The
Guarantee Trustee shall not be liable for any action taken, suffered, or omitted
to be taken by it in good faith and reasonably believed by it to be authorized
or within the discretion or rights or powers conferred upon it by this
Guarantee.
6

(b)No
provision of this Guarantee shall be deemed to impose any duty or obligation on
the Guarantee Trustee to perform any act or acts or exercise any right, power,
duty or obligation conferred or imposed on it, in any jurisdiction in which it
shall be illegal or in which the Guarantee Trustee shall be unqualified or
incompetent in accordance with applicable law to perform any such act or acts or
to exercise any such right, power, duty or obligation. No permissive power or
authority available to the Guarantee Trustee shall be construed to be a
duty.

SECTION

The
recitals contained in this Guarantee shall be taken as the statements of the
Guarantor, and the Guarantee Trustee does not assume any responsibility for
their correctness. The Guarantee Trustee makes no representation as to the
validity or sufficiency of this Guarantee.

SECTION
2.4.Events
of Default; Waiver.

of Default under this Guarantee will occur upon the failure of the Guarantor to
perform any of its payment or other obligations hereunder.

(b)The
Holders of a Majority in liquidation amount of the Capital Securities may,
voting or consenting as a class, on behalf of the Holders of all of the Capital
Securities, waive any past Event of Default and its consequences. Upon such
waiver, any such Event of Default shall cease to exist, and shall be deemed to
have been cured, for every purpose of this Guarantee, but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any
right consequent thereon.

SECTION
2.5.Events
of Default; Notice.

(a)The
Guarantee Trustee shall, within 90 days after the occurrence of an Event of
Default, transmit by mail, first class postage prepaid, to the Holders of the
Capital Securities, notices of all Events of Default actually known to a
Responsible Officer of the Guarantee Trustee, unless such defaults have been
cured before the giving of such notice;provided,however, that
the Guarantee Trustee shall be protected in withholding such notice if and so
long as a Responsible Officer of the Guarantee Trustee in good faith determines
that the withholding of such notice is in the interests of the Holders of the
Capital Securities.

(b)The
Guarantee Trustee shall not be charged with knowledge of any Event of Default
unless the Guarantee Trustee shall have received written notice thereof from the
Guarantor or a Holder of the Capital Securities, or a Responsible Officer of the

direct the exercise of any trust or power conferred upon the Guarantee Trustee
under this Guarantee;provided,however, that
(subject to Sections 2.1 and 2.2) the Guarantee Trustee shall have the right to
decline to follow any such direction if the Guarantee Trustee shall determine
that the actions so directed would be unjustly prejudicial to the Holders not
taking part in such direction or if the Guarantee Trustee being advised by legal
counsel determines that the action or proceeding so directed may not lawfully be
taken or if the Guarantee Trustee in good faith by its board of directors or
trustees, executive committee or a trust committee of directors or trustees

directed would involve the Guarantee Trustee in personal liability.

without first instituting a legal proceeding against the Issuer, the Guarantee

Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

INDEMNIFICATION

SECTION
7.1.Exculpation.

(a)No
Indemnified Person shall be liable, responsible or accountable in damages or
otherwise to the Guarantor or any Covered Person for any loss, damage or claim
incurred by reason of any act or omission of such Indemnified Person in good
faith in accordance with this Guarantee and in a manner that such Indemnified
Person reasonably believed to be within the scope of the authority conferred on
such Indemnified Person by this Guarantee or by law, except that an Indemnified
Person shall be liable for any such loss, damage or claim incurred by reason of
such Indemnified Person’s negligence or willful misconduct with respect to such
acts or omissions.

(b)An
Indemnified Person shall be fully protected in relying in good faith upon the
records of the Issuer or the Guarantor and upon such information, opinions,
reports or statements presented to the Issuer or the Guarantor by any Person as
to matters the Indemnified Person reasonably believes are within such other
Person’s professional or expert competence and who, if selected by such
Indemnified Person, has been selected with reasonable care by such Indemnified
Person, including information, opinions, reports or statements as to the value
and amount of the assets, liabilities, profits, losses, or any other facts
pertinent to the existence and amount of assets from which Distributions to
Holders of Capital Securities might properly be paid.

SECTION
7.2.Indemnification.

(a)The
Guarantor agrees to indemnify each Indemnified Person for, and to hold each
Indemnified Person harmless against, any and all loss, liability, damage, claim
or expense incurred without negligence or willful misconduct on the part of the
Indemnified Person, arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder, including but not limited to
the costs and expenses (including reasonable legal fees and expenses) of the
Indemnified Person defending itself against, or investigating, any claim or
liability in connection with the exercise or performance of any of the
Indemnified Person’s powers or duties hereunder. The obligation to indemnify as
set forth in this Section 7.2 shall survive the resignation or removal of the
Guarantee Trustee and the termination of this Guarantee.
13

(b)Promptly
after receipt by an Indemnified Person under this Section 7.2 of notice of
the commencement of any action, such Indemnified Person will, if a claim in
respect thereof is to be made against the Guarantor under this Section 7.2,
notify the Guarantor in writing of the commencement thereof; but the failure so
to notify the Guarantor (i) will not relieve the Guarantor from liability
under paragraph (a) above unless and to the extent that the Guarantor did not
otherwise learn of such action and such failure results in the forfeiture by the
Guarantor of substantial rights and defenses and (ii) will not, in any
event, relieve the Guarantor from any obligations to any Indemnified Person
other than the indemnification obligation provided in paragraph (a) above. The
Guarantor shall be entitled to appoint counsel of the Guarantor’s choice at the
Guarantor’s expense to represent the Indemnified Person in any action for which
indemnification is sought (in which case the Guarantor shall not thereafter be
responsible for the fees and expenses of any separate counsel retained by the
Indemnified Person or Persons except as set forth below);provided,however, that
such counsel shall be satisfactory to the Indemnified Person. Notwithstanding
the Guarantor’s election to appoint counsel to represent the Indemnified Person
in any action, the Indemnified Person shall have the right to employ separate
counsel (including local counsel), and the Guarantor shall bear the reasonable
fees, costs and expenses of such separate counsel, if (i) the use of
counsel chosen by the Guarantor to represent the Indemnified Person would
present such counsel with a conflict of interest, (ii) the actual or
potential defendants in, or targets of, any such action include both the
Indemnified Person and the Guarantor and the Indemnified Person shall have
reasonably concluded that there may be legal defenses available to it and/or
other Indemnified Persons which are different from or additional to those
available to the Guarantor, (iii) the Guarantor shall not have employed
counsel satisfactory to the Indemnified Person to represent the Indemnified
Person within a reasonable time after notice of the institution of such action
or (iv) the Guarantor shall authorize the Indemnified Person to employ
separate counsel at the expense of the Guarantor. The Guarantor will not,
without the prior written consent of the Indemnified Persons, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
Indemnified Persons are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each Indemnified Person from all liability arising out of such claim, action,
suit or proceeding.
14

SECTION
7.3.Compensation;
Reimbursement of Expenses.

The
Guarantor agrees:

(a)to pay to
the Guarantee Trustee from time to time such compensation for all services
rendered by it hereunder as the parties shall agree to from time to time (which
compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust); and

(b)except as
otherwise expressly provided herein, to reimburse the Guarantee Trustee upon
request for all reasonable expenses, disbursements and advances incurred or made
by it in accordance with any provision of this Guarantee (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be
attributable to its negligence or willful misconduct.

provisions of this Section 7.3 shall survive the resignation or removal of the
Guarantee Trustee and the termination of this Guarantee.
