            Guarantee Unconditional:  The obligations of the Guarantor hereunder are as a primary obligor and not as a surety, are

            any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company under the Indenture or any Security, by operation of law or otherwise;

          


     

    	

          	2.2.2

          	2.2.5	
            any invalidity or unenforceability relating to or against the Company for any reason of the Indenture or any Security, or any provision of applicable law or regulation purporting to prohibit the payment by the

          	2.3	
            Discharge; Reinstatement:  Except as otherwise provided by Clause 2.8 herein, the Guarantor’s obligations hereunder will
              remain in full force and effect until the principal of, premium, if any, and interest on the Securities and all other Obligations payable by the Company on the Securities under the Indenture have been paid in full.  If at any time any payment
              of the principal of, premium, if any, or interest on any such Security or any other amount payable by the Company under the Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of
              the Company or otherwise, the Guarantor’s obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

          


     

    	

          	2.4	
            Waiver by the Guarantor:  The Guarantor irrevocably waives acceptance hereof, diligence, presentment, demand of payment,
              filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever, as well as any requirement that at any time any
              action be taken by any Person against the Company or any other Person.

          


     

    	

          	2.5	
            Stay of Acceleration:  If acceleration of the time for payment of any amount payable by the Company under the Indenture or the
              Securities is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of the Indenture are nonetheless payable by the Guarantor hereunder forthwith without
              demand by the Trustee or the Holders.

          	2.6	
            Benefit of Trustee; Enforceable by Trustee:  This Note Guarantee shall be a continuing guarantee and shall inure to the
              benefit of and be enforceable by the Trustee, its successors and assigns, the Holders, and their successors, transferees and assigns.

          


     

    	

          	2.7	
            Execution and Delivery of Note Guarantee:  The execution by the Guarantor of this Note Guarantee evidences the Note Guarantee,
              whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Security.  Neither the Company nor the Guarantor shall be required to make a notation on the Securities to reflect
              any Note Guarantee or any such release, termination or discharge thereof. The delivery of any Security by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in this Note Guarantee on behalf of the
              Guarantor.

          


     

    	

          	2.8

              discharge of such Securities as provided in the Indenture.

            Waiver; Amendment

          


     

    	

          	3.1	
            Waiver: No failure or delay by the Trustee or any Holder in exercising any right or power hereunder or under the Indenture or the Securities shall operate as a waiver
              thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or
              power.  The rights and remedies of the Trustee and the Holders hereunder and under the Indenture or the Securities are cumulative and are not exclusive of any rights or remedies that they would otherwise have.  No waiver of any provision of
              this Note Guarantee or consent to any departure by the Guarantor therefrom shall in any event be effective unless the same shall be permitted by Clause 3.2, and then such waiver or consent shall be effective only in the specific instance and
              for the purpose for which given.  No notice or demand on the Guarantor in any case shall entitle the Guarantor to any other or further notice or demand in similar or other circumstances.

              the Indenture may be waived with the consent, or compliance with any provision of this Note Guarantee may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities (including
              consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Securities).  Notwithstanding the preceding sentence, the Guarantor, with the Trustee, may modify or amend this Note Guarantee without the consent
