               before the giving of such notice; PROVIDED, that, except in the
               case of a default by Guarantor on any of its payment obligations,
               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 Preferred
               Securities.

          (b)  The Guarantee Trustee shall not be deemed to have knowledge of
               any Event of Default unless the Guarantee Trustee shall have
               received written notice, or of which a Responsible Officer of the
               Guarantee Trustee charged with the administration of the Trust
               Agreement shall have obtained actual knowledge.

     2.8 CONFLICTING INTERESTS.

     The Trust Agreement shall be deemed to be specifically described in this
Preferred Securities Guarantee for the purposes of clause (i) of the first
proviso contained in Section 310(b) of the Trust Indenture Act.

                                   ARTICLE III

                 POWERS, DUTIES AND RIGHTS OF GUARANTEE TRUSTEE

     3.1 POWERS AND DUTIES OF THE GUARANTEE TRUSTEE.

          (a)  This Preferred Securities Guarantee shall be held by the
               Guarantee Trustee for the benefit of the Holders of the Preferred
               Securities, and the Guarantee Trustee shall not transfer this
               Preferred Securities Guarantee to any Person except a Holder of
               Preferred Securities exercising his or her rights pursuant to
               Section 5.4(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 Preferred Securities
               Guarantee for the benefit of the Holders of the Preferred
               Securities.

          (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 Preferred Securities Guarantee,
               and no implied covenants shall be read into this Preferred
               Securities 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
               Preferred Securities 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.

                                       -7-

          (d)  No provision of this Preferred Securities 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 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 Preferred Securities 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
                              Preferred Securities Guarantee, and no implied
                              covenants or obligations shall be read into this
                              Preferred Securities 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 Preferred
                              Securities 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 Preferred Securities
                              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
                       Preferred 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 Preferred Securities Guarantee; and

                                       -8-
<Page>

               (iv)    no provision of this Preferred Securities 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 Preferred
                       Securities Guarantee or indemnity, reasonably
                       satisfactory to the Guarantee Trustee, against such risk
                       or liability is not reasonably assured to it.

     3.2 CERTAIN RIGHTS OF GUARANTEE TRUSTEE.

          (a)  Subject to the provisions of Section 3.1:

               (i)     the Guarantee Trustee may conclusively rely, and shall be
                       fully protected in acting or refraining from acting upon,
                       any resolution, certificate, statement, instrument,
                       opinion, report, notice, request, direction, consent,
                       order, bond, 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 Preferred Securities Guarantee shall be sufficiently
                       evidenced by an Officers' Certificate;

               (iii)   whenever, in the administration of this Preferred
                       Securities 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
                       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, refiling or registration thereof);

               (v)     the Guarantee Trustee may consult with 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

                                       -9-
<Page>

                       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
                       Preferred Securities 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
                       Preferred Securities 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 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 Preferred Securities 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)    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
                       Preferred Securities Guarantee, both of which shall be
                       conclusively evidenced by the Guarantee Trustee's or its
                       agent's taking such action; and

               (x)     whenever in the administration of this Preferred
                       Securities Guarantee the Guarantee Trustee shall deem it
                       desirable to receive

                                      -10-
<Page>

                       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 Preferred
                       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 Preferred Securities 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.

     3.3 NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE.

     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 Preferred Securities Guarantee.

                                   ARTICLE IV

                                GUARANTEE TRUSTEE

     4.1 GUARANTEE TRUSTEE; ELIGIBILITY.

          (a)  There shall at all times be a Guarantee Trustee which shall:

               (i)     not be an Affiliate of the Guarantor; and

               (ii)    be a corporation organized and doing business under the
                       laws of the United States of America or any state or
                       territory thereof or of the District of Columbia, or a
                       corporation or Person permitted by the Securities and
                       Exchange Commission to act as an institutional trustee
                       under the Trust Indenture Act, authorized under such laws
                       to exercise corporate trust powers, having a combined
                       capital and surplus of at least $50,000,000, and subject
                       to supervision or examination by federal, state,
                       territorial or District of Columbia authority. If such
                       corporation publishes reports of condition at least
                       annually, pursuant to law or to the requirements of the

                                      -11-
<Page>

                       supervising or examining authority referred to above,
                       then, for the purposes of this Section 4.1(a)(ii), 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.

          (b)  If at any time the Guarantee Trustee shall cease to be eligible
               to so act under Section 4.1(a), the Guarantee Trustee shall
               immediately resign in the manner and with the effect set out in
               Section 4.2(c).

          (c)  If the Guarantee Trustee has or shall acquire any "conflicting
               interest" within the meaning of Section 310(b) of the Trust
               Indenture Act, the Guarantee Trustee and Guarantor shall in all
               respects comply with the provisions of Section 310(b) of the
               Trust Indenture Act.

     4.2 APPOINTMENT, REMOVAL AND RESIGNATION OF GUARANTEE TRUSTEE.

          (a)  Subject to Section 4.2(b), the Guarantee Trustee may be appointed
               or removed without cause at any time by the Guarantor.

          (b)  The Guarantee Trustee shall not be removed in accordance with
               Section 4.2(a) until a Successor Guarantee Trustee has been
               appointed and has accepted such appointment by written instrument
               executed by such Successor Guarantee Trustee and delivered to the
               Guarantor.

          (c)  The Guarantee Trustee appointed to office shall hold office until
               a Successor Guarantee Trustee shall have been appointed or until
               its removal or resignation. The Guarantee Trustee may resign from
               office (without need for prior or subsequent accounting) by an

               delivered to the Guarantor, which resignation shall not take
               effect until a Successor Guarantee Trustee has been appointed and
               has accepted such appointment by instrument in writing executed
               by such Successor Guarantee Trustee and delivered to the
               Guarantor and the resigning Guarantee Trustee.

               accepted appointment as provided in this Section 4.2 within 60
               days after delivery to the Guarantor of an instrument of
               resignation, the resigning Guarantee Trustee may petition any
               court of competent jurisdiction for appointment of a Successor
               Guarantee Trustee. Such court may thereupon, after prescribing
               such notice, if any, as it may deem proper, appoint a Successor
               Guarantee Trustee.

          (e)  No Guarantee Trustee shall be liable for the acts or omissions to
               act of any Successor Guarantee Trustee.

               or hereby incurred; or

          (h)  any other circumstance whatsoever that might otherwise constitute
               a legal or equitable discharge or defense of a guarantor, it

Guarantor in 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.
