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 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

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 reasonably assured to it under the terms of this Guarantee
Agreement or adequate indemnity against such risk or liability is not reasonably assured to it. 

  
 Section 3.2 Certain Rights of Guarantee Trustee. 
  

	 	(a)	Subject to the provisions of Section 3.1: 

  

	 	(i)	The Guarantee Trustee may rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice,

	 	(iii)	Whenever, in the administration of this Guarantee Agreement, the Guarantee Trustee shall deem it desirable that a matter be proved or established before taking, suffering or
omitting to take 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 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 written advice or opinion of such legal counsel with respect to legal matters shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted to be taken by the Guarantee Trustee hereunder in good faith and in accordance with such advice or opinion. Such legal counsel may be legal counsel to the Guarantor or any of its
Affiliates and may be one of its employees. The Guarantee Trustee shall have the right at any time to seek instructions concerning the administration of this Guarantee Agreement from any court of competent jurisdiction. 

  

	 	(v)	The Guarantee Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Guarantee Agreement at the request or direction of any Trust
Preferred Holder, unless such Trust Preferred Holder shall have provided to the Guarantee Trustee such adequate security and indemnity as would satisfy a reasonable person in the position of the Guarantee Trustee, 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. 

  

	 	(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 discretion, may make such further inquiry or investigation into such facts or matters as it may
see fit. 

  

	 	(vii)	The Guarantee Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys, and the Guarantee
Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it hereunder. 

  

	 	(viii)	Any action taken by the Guarantee Trustee or its agents hereunder shall bind the Trust Preferred 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 

  

 -8- 








 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 Agreement, both of which shall be conclusively evidenced by the Guarantee Trustee’s or its agent’s taking such action. 
  

	 	(ix)	Whenever in the administration of this Guarantee Agreement 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 (A) may request instructions from the Trust Preferred Holders of a Majority in liquidation preference of the Trust Preferred Securities, (B) may refrain from enforcing such remedy or
right or taking such other action until such instructions are received, and (C) shall be protected in acting in accordance with such instructions. 

  
 (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 obligation. No permissive power or authority available to the Guarantee Trustee shall be construed to be a duty to act in accordance with such power and authority.

  
 Section 3.3 Indemnity, Fees. 
  
 The Guarantor agrees to pay to the Guarantee Trustee from time to time
reasonable compensation for all services rendered by the Guarantee Trustee hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). 
  
 The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold it
harmless against, any loss, liability or expense incurred without negligence or bad faith on the part of the Guarantee Trustee, arising out of or in connection with the acceptance or administration of this Guarantee Agreement, including the costs

 As security for such payments referred to in this Section 3.3, the Guarantee Trustee shall have a lien equal to the amount of such payments upon all
Guarantee Payments. 
  
 The provisions of this Section 3.3
shall survive the termination of this Guarantee Agreement or the resignation or removal of the Guarantee Trustee.

 The Guarantor irrevocably and unconditionally agrees to pay in full on a subordinated basis to the Trust Preferred Holders the Guarantee Payments (without
duplication of amounts theretofore paid by or on behalf of the Trust), as and when due, regardless of any defense, right of set-off or counterclaim which the Trust may have or assert. The Guarantor’s obligation to make a Guarantee Payment may
be satisfied by direct payment of the required amounts by the Guarantor to the Trust Preferred Holders or by causing the Trust to pay such amounts to the Trust Preferred Holders. 
  
 Section 5.2 Waiver of Notice and Demand. 
  
 The Guarantor hereby waives notice of acceptance of this Guarantee Agreement and of any liability to which it applies or may
apply, presentment, demand for payment, any right to require a proceeding first against the Guarantee Trustee, Trust or any other Person before proceeding against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice of redemption
and all other notices and demands. 
  
 Section 5.3 Obligations Not
Affected. 
  
 The obligations, covenants, agreements and
duties of the Guarantor under this Guarantee Agreement shall in no way be affected or impaired by reason of the happening from time to time of any of the following: 
  
 (a) the release or waiver, by operation of law or otherwise, of the performance or observance by the Trust of any express or
implied agreement, covenant, term or condition relating to the Trust Preferred Securities to be performed or observed by the Trust; 
  
 (b) the extension of time for the payment by the Trust of all or any portion of the Distributions, Redemption Price, Liquidation Distribution or any other
sums payable under the terms of the Trust Preferred Securities or the extension of time for the performance of any other obligation under, arising out of, or in connection with, the Trust Preferred Securities (other than an extension of time for
payment of Distributions, Redemption Price, Liquidation Distribution or other sums payable that results from the deferral of any interest payment on the Notes permitted by Section 4.1 or 4.2 of the First Supplemental Indenture); 
  
 (c) any failure, omission, delay or lack of diligence on the part of the
Trust Preferred Holders to enforce, assert or exercise any right, privilege, power or remedy conferred on the Trust Preferred Holders pursuant to the terms of the Trust Preferred Securities, or any action on the part of the Trust granting indulgence
or extension of any kind; 
  
 (d) the voluntary or involuntary
liquidation, dissolution, sale of any collateral, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of debt of, or other similar proceedings affecting, the Trust
or any of the assets of the Trust; 
  

 -11- 








 (e) any invalidity of, or defect or deficiency in, the Trust Preferred Securities; 
  
 (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or 
  
 (g) any other circumstance whatsoever that
might otherwise constitute a legal or equitable discharge or defense of a guarantor, it being the intent of this Section 5.3 that the obligations of the Guarantor hereunder shall be absolute and unconditional under any and all circumstances.

  
 There shall be no obligation of the Trust Preferred Holders to
give notice to, or obtain the consent of, the Guarantor with respect to the happening of any of the foregoing. 
  
 Section 5.4 Rights of Trust Preferred Holders. 
  
 The Guarantor expressly acknowledges that: (i) this Guarantee Agreement will be deposited with the Guarantee Trustee to be held for the benefit of the Trust Preferred Holders; (ii) the Guarantee Trustee has
the right to enforce this Guarantee Agreement on behalf of the Trust Preferred Holders; (iii) the Trust Preferred Holders of a Majority in liquidation preference of the Trust Preferred Securities have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Guarantee Trustee in respect of this Guarantee Agreement or exercising any trust or power conferred upon the Guarantee Trustee under this Guarantee Agreement; and (iv) if the
Guarantee Trustee fails to enforce this Guarantee Agreement after a Trust Preferred Holder has made a written request for the Guarantee Trustee to do so, any Trust Preferred Holder may, to the extent permitted by law, institute a legal proceeding
directly against the Guarantor to enforce its rights under this Guarantee Agreement, without first instituting a legal proceeding against the Guarantee Trustee, the Trust or any other Person. Notwithstanding the foregoing, if the Guarantor has
failed to make a Guarantee Payment, a Trust Preferred Holder may directly institute a proceeding against the Guarantor for enforcement of this Guarantee Agreement for such payment. The Guarantor waives any right or remedy to require that any action
on this Guarantee Agreement be brought first against the Trust or any other Person or entity before proceeding directly against the Guarantor. 
  
 Section 5.5 Guarantee of Payment. 
  
 This Guarantee Agreement creates a guarantee of payment and not of collection. This Guarantee Agreement will not be discharged except by payment of the
Guarantee Payments in full (without duplication of amounts theretofore paid by the Trust). 
  
 Section 5.6 Subrogation. 
  
 The Guarantor shall be subrogated to all (if any) rights of the Trust Preferred Holders against the Trust in respect of any amounts paid to the Trust Preferred Holders by the Guarantor under this Guarantee Agreement and shall have the right
to waive payment by the Trust pursuant to Section 5.1; provided, however, that the Guarantor shall not (except to the extent required by mandatory provisions of law) be entitled to enforce or exercise any rights which it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all cases as a result of payment under this Guarantee Agreement if, at the time of any such payment, any 
  

 -12- 








 amounts are due and unpaid under this Guarantee Agreement. 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 Trust Preferred Holders and to pay over such amount to the Trust Preferred Holders. 
  
 Section 5.7 Independent Obligations. 
  

The Guarantor acknowledges that its obligations hereunder are independent of the obligations of the Trust with respect to the Trust Preferred
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 Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof. 
  
 ARTICLE VI. COVENANTS AND SUBORDINATION

full payment of the amounts payable in accordance with the Declaration of Trust upon liquidation of the Trust. Notwithstanding the foregoing, this Guarantee Agreement will continue to be effective or will be reinstated, as the case may be, if at any
time any Trust Preferred Holder must restore payment of any sums paid with respect to Trust Preferred Securities or this Guarantee Agreement.
