                              to have been given to the Guarantee Trustee by the
                              Guarantor. The Guarantee Trustee may destroy any
                              List of Holders previously given to it on receipt

          The Holders of a Majority in Liquidation Amount of Preferred
Securities may, by vote, on behalf of the Holders of all of the Preferred
Securities, waive any past Event of Default and its consequences. Upon such
waiver, any such Event of Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured, for every purpose of this

                              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, that, except in the case of a default by
                              Guarantor on any of its payment obligations, the

                              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 (i) the
                              Guarantee Trustee shall have received written
                              notice of such Event of Default, or (ii) a
                              Responsible Officer of the Guarantee Trustee
                              charged with the administration of the Trust
                              Agreement shall have obtained actual knowledge of
                              such Event of Default.

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.

                    (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

                                                  Securities Guarantee, and no
                                                  implied covenants or
                                                  obligations shall be read
                                                  into this Preferred Securities

                                        (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

                                        grounds for believing that the repayment
                                        of such funds or liability is not
                                        reasonably assured to it under the terms

                              accepted such appointment by written instrument
                              executed by such Successor Guarantee Trustee and

Holders of Preferred Securities against the Trust in respect of any amounts paid
to such Holders by the Guarantor under this Preferred Securities Guarantee;
PROVIDED, HOWEVER, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any right
that it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Preferred
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Preferred Securities Guarantee. If any amount shall be
paid to the 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.

          So long as any Preferred Securities remain outstanding, if there shall
have occurred an Event of Default under this Preferred Securities Guarantee, an
event of default under the Trust Agreement or during an Extended Interest
Payment Period (as defined in the Indenture), then (a) the Guarantor shall not
declare or pay any dividend on, make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock (other than as a result of a reclassification of its capital
stock for another class of its capital stock) and (b) the Guarantor shall not
make any payment of interest or principal on or repay, repurchase or redeem any
debt securities issued by the Guarantor which rank pari passu with or junior to
the Debentures other than payments under this Preferred Securities Guarantee.

          6.2 Ranking.

          This Preferred Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank subordinate and junior in right of
payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations,
as defined in the Indenture, of the Guarantor, to the extent and in the manner
set forth in the Indenture, and the applicable provisions of the Indenture will
apply, in all relevant respects, to the obligations of the Guarantor hereunder.

VII       TERMINATION

          7.1 Termination.

          This Preferred Securities Guarantee shall terminate upon (i) full
