			WHEREAS, each of the Issuers, the Guarantors and the Trustee have heretofore executed and delivered an indenture dated as of May 5, 2015 (as amended, supplemented, waived or otherwise modified, the “Indenture”), providing for the issuance of (i) €375.0 million aggregate principal amount of 6.375% Senior Notes due 2022, issued on the date thereof (the “Euro Notes”) and (ii) $300.0 million aggregate principal amount of 6.750% Senior Notes due 2022, issued on the date thereof (the “Dollar Notes”, and together with the Euro Notes, the “Initial Notes”) (the Initial Notes and any Additional Notes are collectively referred to as the “Notes”);
		

		
			WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture to which the Guaranteeing Subsidiary shall unconditionally guarantee, on a joint and several basis with the other Guarantors, all of the Issuers’ obligations under the Notes and the Indenture on the terms and conditions set forth herein and under the Indenture (the “Guarantee”); 
		

		
			WHEREAS, pursuant to Section 9.1 of the Indenture, the Issuers, any Guarantor and the Trustee are authorized to execute and deliver this Supplemental Indenture to amend or supplement the Indenture, without the consent of any Holder; and
		

		
			WHEREAS, pursuant to Section 9.1 of the Indenture, the Issuers hereby request that the Trustee join with the Issuers, the Guarantors and the Guaranteeing Subsidiary in the execution of this Supplemental Indenture.
		

		
			NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary, the Issuers, the other Guarantors and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:
		

		
			ARTICLE I

DEFINITIONS
		

		
			SECTION 1.1.Defined Terms.  As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recitals hereto are used herein as therein defined.  The words “herein,” 


		 


 


“hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.
		

		
			ARTICLE II

AGREEMENT TO BE BOUND; GUARANTEE
		

		
			SECTION 2.1.Agreement to Be Bound.  The Guaranteeing Subsidiary hereby becomes a party to the Indenture as a Guarantor and as such will have all of the rights and be subject to all of the obligations and agreements of a Guarantor under the Indenture.
		

		
			SECTION 2.2.Guarantee.  The Guaranteeing Subsidiary agrees, on a joint and several basis with all the existing Guarantors, to fully, unconditionally and irrevocably Guarantee to each Holder of the Notes and the Trustee the Guaranteed Obligations pursuant to Article X of the Indenture on a senior basis. 
		

		
			(a) The aggregate liability of the Guaranteeing Subsidiary for Restricted Obligations (as defined in Schedule I to the Indenture) shall be limited to the amount available for distribution as dividends to the shareholders of the Guaranteeing Subsidiary at the time the Guaranteeing Subsidiary is required to perform under any Transaction Document, provided that this is a requirement under applicable Swiss law at that time and further provided that such limitation shall not discharge the Guaranteeing Subsidiary from its obligations in excess thereof, but merely postpone the performance date thereof until such times as performance is again permitted notwithstanding such limitation. Any and all indemnities and guarantees contained in the Transaction Documents shall be construed in a manner consistent with the provisions herein contained.
		

		
			(b) In respect of Restricted Obligations, the Guaranteeing Subsidiary shall:
		

		
			(1) if and to the extent required by applicable law in force at the relevant time use its best efforts to mitigate to the extent possible any obligation with respect to withholding tax in accordance with the Federal Act on Anticipatory Tax of 13 October 1965, as amended (Bundesgesetz über die Verrechnungssteuer) ("Swiss Withholding Tax") to be levied on the Restricted Obligations (and cause its parent and other relevant Affiliates to fully cooperate in any mitigating efforts), in particular through the notification procedure, and promptly notify the Trustee thereof or, if such a notification procedure is not applicable:
		

		
			(A) deduct Swiss Withholding Tax at the rate of 35 per cent. (or such other rate as in force from time to time pursuant to, in particular, any applicable double taxation treaty) from any payment made by it in respect of Restricted Obligations; 
		

		
			(B) pay any such deduction to the Swiss Federal Tax Administration; and
		

		
			(C) notify (and the Issuers shall ensure that the Guaranteeing Subsidiary will notify) the Trustee that such a deduction has been made and provide the Trustee with evidence that such a deduction has been paid to the Swiss Federal Tax Administration; and
		

		
			(2) to the extent such a deduction is made, not be obliged to pay Additional Amounts in relation to any such payment made by it in respect of Restricted Obligations unless such payment is permitted under the laws of Switzerland then in force (it being understood that this shall not in any way limit 


		 


 


any obligations of any other Guarantor or the Issuers under any Transaction Document to indemnify the Holders of the Notes and the Trustee in respect of the deduction of the Swiss Withholding Tax). The Guaranteeing Subsidiary shall use its commercially reasonable efforts to ensure that any Person which is, as a result of a deduction of Swiss Withholding Tax, entitled to a full or partial refund of the Swiss Withholding Tax, will, as soon as possible after the deduction of the Swiss Withholding Tax, (i) request a refund of the Swiss Withholding Tax under any applicable law (including double tax treaties) and (ii) promptly upon receipt, pay to the Trustee (or to any such other Person as directed by the Trustee) any amount so refunded for application as a further payment of the Guaranteeing Subsidiary under and pursuant to the relevant Transaction Document.
		

		
			(c) If and to the extent requested by the Trustee and if and to the extent this is from time to time required under Swiss law (restricting profit distributions), in order to allow the Holders of the Notes and the Trustee to obtain a maximum benefit under Article X of the Indenture, the Guaranteeing Subsidiary shall, and any parent company of the Guaranteeing Subsidiary being a party to the Indenture shall procure that the Guaranteeing Subsidiary will, promptly implement all such measures and/or promptly procure the fulfillment of all prerequisites allowing it to promptly make the (requested) payment(s) hereunder from time to time, including the following:
		

		
			(1) preparation of an up-to-date audited balance sheet of the Guaranteeing Subsidiary;
		

		
			(2) confirmation of the auditors of the Guaranteeing Subsidiary that the relevant amount represents (the maximum of) freely distributable profits;
		

		
			(3) conversion of restricted reserves into profits and reserves freely available for the distribution as dividends (to the extent permitted by mandatory Swiss law);
		

		
			(4) revaluation of hidden reserves (to the extent permitted by mandatory Swiss law);
		

		
			(5) approval by a shareholders’ meeting of the Guaranteeing Subsidiary of the (resulting) profit distribution; and
		

		
			(6) all such other measures necessary or useful to allow the Guaranteeing Subsidiary to make the payments agreed hereunder with a minimum of limitations.
		

		
			 
		

		
			ARTICLE III
