Pursuant to Section 2.6 of this Second Supplemental Indenture, the provisions in the First Supplemental Indenture relating to the Existing Guarantee shall apply to the Additional Guarantee. 
(b)    The Additional Guarantor hereby waives notice of acceptance of the Additional Guarantee and of default of performance by the Company and the Existing Guarantor, and hereby agrees that payment under the Additional Guarantee shall be subject to no condition other than the giving of a written request for payment stating the fact of default of performance, in the manner provided in Section 1.05 of the Base Indenture. The Additional Guarantee is a guarantee of payment and not of collection.
(c)    The obligations of the Additional Guarantor under the Additional Guarantee shall in no way be impaired by: (i) any extension, amendment, modification or renewal of the Securities of the relevant series; (ii) any waiver of any Event of Default, extension of time or failure to enforce any of the provisions of the Securities of the relevant series or the Indenture; or (iii) any extension, moratorium or other relief granted to the Company or the Existing Guarantor pursuant to any applicable law or statute.
(d)    The Additional Guarantor shall be obligated to make payment under the Additional Guarantee, for the benefit of the Holders of each series of Securities, in the same manner in which the Company is obligated to make payments on such series of Securities.
(e)    Subject to clause (f) below, the Additional Guarantor hereby agrees that:
(i)    each series of Securities will be paid strictly in accordance with the terms of such series of Securities and the Indenture, regardless of the value, genuineness, validity, regularity or enforceability of such series of Securities and the Indenture, and of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Trustee with respect thereto, to the fullest extent permitted by law; and
(ii)    the liability of the Additional Guarantor to the extent herein set forth shall be absolute and unconditional, not subject to any reduction, limitation, impairment, termination, defense, offset, counterclaim, or recoupment whatsoever (all of which are hereby expressly waived by the Additional Guarantor), whether by reason 











of any claim of any character whatsoever, including, without limitation, any claim of waiver, release, surrender, alteration or compromise, or by reason of any liability at any time to the Additional Guarantor or otherwise, whether based upon any obligations or any other agreement or otherwise, and howsoever arising, whether out of action or inaction or otherwise and whether resulting from default, willful misconduct, negligence or otherwise, and without limiting the foregoing, irrespective of:
(1)    any lack of validity or enforceability of any agreement or instrument relating to the Securities of the relevant series;
(2)    any change in the time, manner or place of payment under, or in any other term in respect of, all or any Securities of the relevant series, or any other amendment or waiver of or consent to any departure from any other agreement relating to such series of Securities;
(3)    any increase in, addition to, exchange or release of, or nonperfection of any lien on or security interest in, any collateral, or any release or amendment or waiver of or consent to any departure from or failure to enforce any other guarantee, for all or any Securities of the relevant series;
(4)    any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Company or the Existing Guarantor in respect the Securities of the relevant series;
(5)    the absence of any action on the part of the Trustee to obtain payment under the Securities of the relevant series or the Indenture from the Company or the Existing Guarantor;
(6)    any insolvency, bankruptcy, reorganization or dissolution, or any similar proceeding of or in respect of the Company or the Existing Guarantor, including, without limitation, rejection of the Securities of the relevant series in such bankruptcy; or
(7)    the absence of notice or any delay in any action to enforce any provision of the Securities of the relevant series or the Indenture or to exercise any right or remedy against the Additional Guarantor, the Existing Guarantor or the Company, whether under the Indenture, the Securities of the relevant series or any agreement or any indulgence, compromise or extension granted.
(f)    Notwithstanding anything to the contrary in the Additional Guarantee herein, the Additional Guarantor does not waive any defense that would be available to the Company or the Existing Guarantor based on a breach, default or misrepresentation by the Trustee, or failure of any condition to the Company’s or the Existing Guarantor’s obligations under the Indenture or the illegality of any provision of the Indenture.
(g)    The Additional Guarantor further agrees that, to the extent that the Company, the Existing Guarantor or the Additional Guarantor make a payment or payments to the Trustee, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or repaid to the Company, the Existing Guarantor or the Additional Guarantor or their respective estate, trustee, receiver or any other party under any bankruptcy laws, state or federal law, common law or equitable cause, then to the extent of such payment or repayment, the Additional Guarantee and the advances or part thereof which have been paid, reduced or satisfied by such amount shall be reinstated and continued in full force and effect as of the date such initial payment, reduction or satisfaction occurred.
Section 2.2    Additional Guarantee for the Benefit of the Holders.
The Additional Guarantee contained in this Second Supplemental Indenture is entered into by the Additional Guarantor for the benefit of the Holders from time to time of the Securities. Such provisions shall not be deemed to create any right, or to be in whole or in part for the benefit, of any Person other than the Trustee, the Additional Guarantor, the Holders from time to time of the Securities and their permitted successors and assigns.













Section 2.3    Waiver of Subrogation. 
The Additional Guarantor shall be subrogated to all rights of the Holders of the Securities and the Trustee against the Company and the Existing Guarantor pursuant to the provisions of the Additional Guarantee; provided, however, that the Additional Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until the principal of (and premium, if any) or interest on the Securities of the relevant series issued under the Indenture shall have been paid in full.
Section 2.4    No Suspension of Remedies.
Nothing contained in this Article II shall limit the right of the Trustee or the Holders of the Securities to take any action pursuant to Article V of the Base Indenture or to pursue any other rights or remedies under the Indenture or under applicable law.
Section 2.5    Termination.
The Additional Guarantee shall remain in full force and effect and shall be binding on the Additional Guarantor and its successors until the entire principal of and interest and any premium on the Securities shall have been paid in full or otherwise discharged in accordance with the provisions of the Indenture.
Section 2.6    References to Guarantor.
From and after the date hereof, (a) each reference to “the Guarantor” and “the Guarantee” in the Base Indenture, the First Supplemental Indenture and the Notes shall be deemed to be a reference to “each Guarantor”, “a Guarantor” or “such Guarantor” and “each Guarantee”, “a Guarantee” or “such Guarantee”, each as the context so requires (including, without limitation, in relation to the subordination provisions of Article V of the First Supplemental Indenture, which shall also apply to the Additional Guarantee); (b) each reference to “(other than the Company)” in Section 8.01(b) of the Base Indenture shall be deemed to be a reference to “(other than the Company or any Guarantor)”; and (c) the provisions of Section 8.01(b) of the Base Indenture that are expressed to apply to “the Guarantor” shall also apply to the Additional Guarantor.
