      WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the

under this Guarantee.

      NOW, THEREFORE, in consideration of the purchase by each Holder, which
purchase the Guarantor hereby agrees shall benefit the Guarantor, the Guarantor
executes and delivers this Guarantee for the benefit of the Holders.

enforce this Guarantee for the benefit of the Holders.

      (c) The Guarantee Trustee, before the occurrence of any Event of Default
and after the curing or waiver 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 2.6) 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 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, 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

                  (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; but in the case of any
      such certificates or opinions that by any provision hereof 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 Guarantee;

            (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; 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 or
      liability is not reasonably assured to it under the terms of this
      Guarantee or indemnity, reasonably satisfactory to the Guarantee Trustee,
      against such risk or liability is not reasonably assured to it.

      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, 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 any rerecording,

            (v) The Guarantee Trustee may consult with competent legal counsel,
      and the written advice or 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

      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 Trustees, 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 that,
      nothing contained in this Section 3.2 (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


                                        7
   11
      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, 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 (i) may request instructions from the Holders of a
      Majority in liquidation amount of the Securities, (ii) may refrain from
      enforcing such remedy or right or taking such other action until such
      instructions are received, and (iii) shall be protected in conclusively
      relying on or acting in accordance with such instructions.

      (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.

      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

amounts by the Guarantor to the Holders or by causing the Issuer to pay such
amounts to the Holders.

SECTION 5.2 Waiver of Notice and Demand

violation of the preceding sentence, the Guarantor agrees to hold such amount in
trust for the Holders and to pay over such amount to the Holders.

the Declaration, will rank subordinate to all of the Guarantor's senior
unsecured obligations except those made subordinate hereto or pari passu
herewith by their terms.
