the Holders, and the Guarantee Trustee shall not transfer this Guarantee
Agreement to any Person except a Holder exercising his or her rights pursuant to
Section 5.04(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 Guarantee Agreement for the benefit of the

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 Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.06), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee 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 Guarantee Agreement shall be construed
to relieve the Guarantee Trustee from liability for its own negligent action,
its own negligent failure to act or 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 Guarantee
               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 Guarantee 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
               Guarantee Agreement; but in the case of any such certificates or
               opinions that by any provision hereof or of the Trust Indenture
               Act are specifically required to be furnished to the Guarantee
               Trustee, the Guarantee Trustee shall be under a duty to

                                       6
<PAGE>

               examine the same to determine whether or not they conform to the
               requirements of this Guarantee 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
     Liquidation Amount of the 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 Agreement; and

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

         SECTION 3.02. Certain Rights of Guarantee Trustee. (a) Subject to the

     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 Officers' Certificate 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 advice or written opinion of such legal counsel with respect to legal

     exercise any of the rights or powers vested in it by this Guarantee
     Agreement 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 it, 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 3.02(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 Guarantee
     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

     responsible for any misconduct or negligence on the part of any agent or
     attorney appointed with due care by it hereunder.

               (b)    No provision of this Guarantee 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

                          ---------------------------

         SECTION 6.01. Subordination. This Guarantee Agreement will constitute
                       -------------
an unsecured obligation of the Guarantor and will rank subordinate and junior in
right of payment to all Senior Debt of the Guarantor, to the same extent and in
the same manner that the Junior Subordinated Debt Securities are subordinated to
Senior Debt pursuant to the Indenture, it being understood that the terms of
Article XIII of the Indenture shall apply to the obligations of the Guarantor
