      Guarantee shall be held by the Guarantee Trustee for the benefit of the Holders
      of the Capital Securities, and the Guarantee Trustee shall not transfer this
      Guarantee to any Person except a Holder of Capital Securities exercising his
      or

(b)  If
      an
      Event of Default actually known to a Responsible Officer of the Guarantee

      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 2.4(b)) 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 all
      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


-
          4 -


(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 furnished to the Guarantee
      Trustee, the Guarantee Trustee shall be under a duty to examine the same to
      determine whether or not on their face 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 such Responsible Officer of the Guarantee Trustee or 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 written direction
      of the Holders of not less than a Majority in liquidation amount of the Capital
      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 is not reasonably assured to it under the
      terms
      of this Guarantee, or security and indemnity, reasonably satisfactory to the
      Guarantee Trustee, against such risk or liability is not reasonably assured
      to
      it.

      sufficiently evidenced by an Officer's Certificate.


-

      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 Officer's Certificate of the Guarantor
      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 other writing (or any rerecording, refiling

      reregistration thereof).




(v)  The
      Guarantee Trustee may consult with counsel of its selection, and the advice
      or

      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

      any
      time to seek instructions concerning the administration of this Guarantee from

(vi)  The
      Guarantee Trustee shall be under no obligation to exercise any of the rights
      or
      powers vested in it by this 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 , however ,
      that
      nothing contained in this Section 2.2(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.

      any duties hereunder either directly or by or through agents, nominees,

      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

      instructions from the Holders of a Majority in liquidation amount of the Capital
      Securities, (B) may refrain from enforcing such remedy or right or taking such

(xi)  The
      Guarantee Trustee shall not be liable for any action taken, suffered, or omitted
      to be taken by it in good faith and reasonably believed by it to be authorized
      or within the discretion or rights or powers conferred upon it by this
      Guarantee.




(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

      Holders of a Majority in liquidation amount of the Capital Securities may,
      voting or consenting as a class, on behalf of the Holders of all of the Capital
      Securities, waive any past Event of Default and its consequences. Upon such
      waiver, any such Event of Default shall cease to exist, and shall be deemed
      to
      have been cured, for every purpose of this Guarantee, but no such waiver shall
      extend to any subsequent or other default or Event of Default or impair any
      right consequent thereon.

      Capital Securities, notices of all Events 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 , however ,
      that
      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

      Capital Securities.




(b)  The
      Guarantee Trustee shall not be charged with knowledge of any Event of Default
      unless the Guarantee Trustee shall have received written notice thereof from
      the
      Guarantor or a Holder of the Capital Securities, or a Responsible Officer of

      to
      decline to follow any such direction if the Guarantee Trustee shall determine
      that the actions so directed would be unjustly prejudicial to the Holders not
      taking part in such direction or if the Guarantee Trustee being advised by
      legal
      counsel determines that the action or proceeding so directed may not lawfully
      be
      taken or if the Guarantee Trustee in good faith by its board of directors or
      trustees, executive committee or a trust committee of directors or trustees
      and/or Responsible Officers shall determine that the action or proceeding so
      directed would involve the Guarantee Trustee in personal liability.




(b)  Any
      Holder of Capital Securities may institute a legal proceeding directly against
      the Guarantor to enforce the Guarantee Trustee's rights under this Guarantee,
      without first instituting a legal proceeding against the Issuer, the Guarantee
      Trustee or any other Person. The Guarantor waives any right or remedy to require
      that any such action be brought first against the Issuer, the Guarantee Trustee
      or any other Person before so proceeding directly against the

      as a result of payment under this Guarantee, if, after giving effect to any
      such
      payment, any amounts are due and unpaid under this 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.




SECTION

      obligations of the Issuer with respect to the Capital Securities and that the
      Guarantor shall be liable as principal and as debtor hereunder to make Guarantee
      Payments pursuant to the terms of this Guarantee notwithstanding the occurrence
      of any event referred to in subsections (a) through (g), inclusive, of Section
      4.3 hereof.




SECTION
      4.8. Enforcement.




A
      Beneficiary may enforce the Obligations of the Guarantor contained in

      other person or entity before proceeding against the Guarantor.

      extension thereof, shall have commenced and be continuing, then the Guarantor
      may not (x) declare or pay any dividends or distributions on, or redeem,
      purchase, acquire, or make a liquidation payment with respect to, any of the
      Guarantor's capital stock or (y) make any payment of principal of or interest
      or

      with a dividend reinvestment or stockholder stock purchase plan or (C) in

      convertible into or exercisable for such capital stock), as consideration in
      an
      acquisition transaction entered into prior to the occurrence of the Event of
      Default or the applicable Extension Period, (iii) as a result of any exchange,
      reclassification, combination or conversion of any class or series of the
      Guarantor's capital stock (or any capital stock of a subsidiary of the
      Guarantor) for any class or series of the Guarantor's capital stock or of any
      class or series of the Guarantor's indebtedness for any class or series of
      the

      or
      ranks *pari

SECTION
      5.2. Ranking.




This
      Guarantee will constitute an unsecured obligation of the Guarantor and will
      rank
      subordinate and junior in right of payment to all present and future Senior
      Indebtedness (as defined in the Indenture) of the Guarantor. By their acceptance
      thereof, each Holder of Capital Securities agrees to the foregoing provisions
      of
      this Guarantee and the other terms set forth herein.




The
      right
      of the Guarantor to participate in any distribution of assets of any of its
      subsidiaries upon any such subsidiary's liquidation or reorganization or
      otherwise is subject to the prior claims of creditors of that subsidiary, except
      to the extent the Guarantor may itself be recognized as a creditor of that
      subsidiary. Accordingly, the Guarantor's obligations under this Guarantee will
      be effectively subordinated to all existing and future liabilities of the
      Guarantor's subsidiaries, and claimants should look only to the assets of the
      Guarantor for payments thereunder. This Guarantee does not limit the incurrence
      or issuance of other secured or unsecured debt of the Guarantor, including
      Senior Indebtedness of the Guarantor, under any indenture or agreement that
      the
      Guarantor may enter into in the future or otherwise.

INDEMNIFICATION




SECTION

      otherwise to the Guarantor or any Covered Person for any loss, damage or claim
      incurred by reason of any act or omission of such Indemnified Person in good
      faith in accordance with this Guarantee and in a manner that such Indemnified
      Person reasonably believed to be within the scope of the authority conferred
      on
      such Indemnified Person by this Guarantee or by law, except that an Indemnified
      Person shall be liable for any such loss, damage or claim incurred by reason
      of
      such Indemnified Person's negligence or willful misconduct with respect to
      such
      acts or omissions.




(b)  An
      Indemnified Person shall be fully protected in relying in good faith upon the
      records of the Issuer or the Guarantor and upon such information, opinions,
      reports or statements presented to the Issuer or the Guarantor by any Person
      as
      to matters the Indemnified Person reasonably believes are within such other
      Person's professional or expert competence and who, if selected by such

      and amount of the assets, liabilities, profits, losses, or any other facts
      pertinent to the existence and amount of assets from which Distributions to
      Holders of Capital Securities might properly be paid.




SECTION
      7.2. Indemnification.




(a)  The
      Guarantor agrees to indemnify each Indemnified Person for, and to hold each
      Indemnified Person harmless against, any and all loss, liability, damage, claim

      the
      Indemnified Person, arising out of or in connection with the acceptance or
      administration of the trust or trusts hereunder, including but not limited
      to

      Indemnified Person defending itself against, or investigating, any claim or
      liability in connection with the exercise or performance of any of the
      Indemnified Person's powers or duties hereunder. The obligation to indemnify

(b)  Promptly
      after receipt by an Indemnified Person under this Section 7.2 of notice of
      the
      commencement of any action, such Indemnified Person will, if a claim in respect
      thereof is to be made against the Guarantor under this Section 7.2, notify
      the
      Guarantor in writing of the commencement thereof; but the failure so to notify
      the Guarantor (i) will not relieve the Guarantor from liability under paragraph
      (a) above unless and to the extent that the Guarantor did not otherwise learn
      of
      such action and such failure results in the forfeiture by the Guarantor of
      substantial rights and defenses and (ii) will not, in any event, relieve the
      Guarantor from any obligations to any Indemnified Person other than the
      indemnification obligation provided in paragraph (a) above. The Guarantor shall
      be entitled to appoint counsel of the Guarantor's choice at the Guarantor's
      expense to represent the Indemnified Person in any action for which
      indemnification is sought (in which case the Guarantor shall not thereafter
      be
      responsible for the fees and expenses of any separate counsel retained by the
      Indemnified Person or Persons except as set forth below); provided , however ,
      that
      such counsel shall be satisfactory to the Indemnified Person. Notwithstanding
      the Guarantor's election to appoint counsel to represent the Indemnified Person

      or
      potential parties to such claim or action) unless such settlement, compromise
      or
      consent includes an unconditional release of each Indemnified Person from all
      liability arising out of such claim, action, suit or proceeding.
