Section 3.1  Powers and Duties of the Guarantee Trustee.
             ------------------------------------------

     (a)  This Agreement shall be held by the Guarantee Trustee for the benefit
of the Holders, and the Guarantee Trustee shall not transfer this Agreement to
any Person except a Holder exercising his or her rights pursuant to Section
5.4(iv) 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, upon acceptance by such Successor Guarantee
Trustee of its appointment hereunder, 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 has occurred and is continuing, the Guarantee
Trustee shall enforce this Agreement for the benefit of the Holders.

     (c)  The Guarantee Trustee, before the occurrence of any Event of Default
and after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Agreement, and no implied covenants shall be read into this Agreement against
the Guarantee Trustee. In case an Event of Default has occurred (that has not
been cured or waived pursuant to Section 2.6), the Guarantee Trustee shall
exercise such of the rights and powers vested in it by this Agreement, 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 Agreement 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 such 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 Agreement, and the
     Guarantee Trustee shall not be liable except for the performance of such
     duties and obligations as are specifically set forth in this Agreement; and

                B)  in the 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 Agreement; but in the case of any
     such certificates or opinions that by any provision hereof or of the Trust

<PAGE>

     Indenture Act are specifically required to be furnished to the Guarantee
     Trustee, the Guarantee Trustee shall be under a duty to examine the same to
     determine whether or not they conform to the requirements of this
     Agreement;

        (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 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
direction of the Holders of not less than a Majority in Principal Amount of the
Debt 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 Agreement; and

        (iv)    no provision of this Agreement 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 or liability is not reasonably
assured to it under the terms of this Agreement or adequate indemnity against
such risk or liability is not reasonably assured to it.

Section 3.2  Certain Rights of Guarantee Trustee.

reasonably believed by it to be genuine and to have been signed, sent or

taking, suffering or omitting to take any action hereunder, the Guarantee

which, upon receipt of such request from the Guarantee Trustee, shall be
promptly delivered by the Guarantor.

        (iv)    The Guarantee Trustee may consult with legal counsel, and the
written advice or opinion of such legal counsel with respect to legal matters

accordance with such advice or opinion. Such legal counsel may be legal counsel
to the Guarantor or any of its Affiliates and may be one of its employees. The

<PAGE>

Guarantee Trustee shall have the right at any time to seek instructions
concerning the administration of this Agreement from any court of competent
jurisdiction.

        (v)     The Guarantee Trustee shall be under no obligation to exercise
any of the rights or powers vested in it by this Agreement at the request or
direction of any Holder, unless such Holder shall have provided to the Guarantee

person in the position of the Guarantee Trustee, against the costs, expenses
(including attorneys' fees and expenses) 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 that, nothing
                                                       --------
contained in this Section 3.2(a)(v) 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 Agreement.

        (vi)    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.

        (vii)   The Guarantee Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through its
agents or attorneys, and the Guarantee 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.

        (viii)  Whenever in the administration of this Agreement 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, (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 acting in accordance
with such instructions.

     (b)  No provision of this Agreement 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 to act in accordance with such power and authority.

Section 3.3  Compensation; Indemnity; Fees.
             -----------------------------

     The Guarantor agrees:

     (a)  to pay to the Guarantee Trustee from time to time reasonable
