 ARTICLE III 
 NOTE GUARANTEES 
 Section 3.01 Agreement to Guarantee. Subject to the
limitations set out in Section 3.02 and 3.03, each New Guarantor hereby agrees, jointly and severally with the other Note Guarantors, irrevocably, fully and unconditionally, to guarantee the Obligations under the Indenture and the
Notes on the terms and subject to the conditions set forth in Article X of the Indenture and to be bound by (and shall be entitled to the benefits of) all other applicable provisions of the Indenture as a Note Guarantor. 

Section 3.02 French Guarantee Limitation. 
 (a) The obligations of any New Guarantor incorporated in France (a “French Note Guarantor”) are subject to the limitations set out in this Section 3.02. 

(b) The obligations and liabilities of any French Note Guarantor under the Indenture and the Notes, and in particular under this
Article III and Article X of the Indenture, shall not include any obligation or liability which, if incurred, would constitute the provision of financial assistance within the meaning of article L.225-216 of the French Commercial Code
and/or would constitute a misuse of corporate assets within the meaning of article(s) L. 241-3 or L. 242-6 of the French Commercial Code or any other law or regulations having the same effect, as interpreted by French courts. 

(c) The obligations and liabilities of any French Note Guarantor under this Article III and Article X of the Indenture for
the Issuer’s obligations under the Indenture and the Notes shall be limited, at any time, to an amount equal to the aggregate of all amounts made available under the Notes and the Indenture to the Issuer to the extent directly or indirectly
on-lent to such French Note Guarantor and/or its direct and indirect Subsidiaries under intercompany loan agreements (excluding, for the avoidance of doubt, any cash-pooling arrangements or other cash management agreements, provided that the
proceeds of the Notes shall not be used, in whole or in part, to finance, directly or indirectly, such cash pooling arrangements or other cash management agreements) and outstanding at the date a payment is to be made by such French Note
Guarantor under this Article III and Article X of the Indenture, it being specified that any payment made by a French Note Guarantor under this Article III and Article X of the Indenture in respect of the obligations of
the Issuer shall reduce pro tanto the outstanding amount of the intercompany loans due by such French Note Guarantor or its relevant direct or indirect Subsidiary under the intercompany loan agreements referred to above and that any repayment
of the intercompany loans by the French Note Guarantor or its relevant direct or indirect Subsidiary shall reduce pro tanto the amount payable by the French Note Guarantor under this Article III and Article X of the Indenture.

 (d) It is acknowledged that no French Note Guarantor is acting jointly and severally with the other Note Guarantors and no
French Guarantor shall therefore be considered as “co-débiteur solidaire” as to its obligations pursuant to the guarantee given pursuant to this Article III and Article X of the Indenture.

 Section 3.03 Swiss Guarantee Limitation. 

(a) The obligations of any New Guarantor incorporated in Switzerland (a “Swiss Note Guarantor”) are subject to the
limitations set out in this Section 3.03. 
 (b) The obligations and liabilities of a Swiss Note Guarantor under the
Indenture, the Notes or any other agreement, and in particular under this Article III and Article X of the Indenture, in relation to the obligations, undertakings, indemnities or liabilities of a Note Guarantor other than that Swiss
Note Guarantor or any of its fully owned and controlled subsidiaries (the “Restricted Obligations”) shall not include any obligation or liability which, if incurred, would constitute the provision of financial assistance not
permitted under the laws of Switzerland then in force and/or would constitute a misuse of corporate assets under Swiss law as interpreted by Swiss courts and shall be limited to the amount of that Swiss Note Guarantor’s Free Reserves Available
for Distribution at the time payment is requested, provided that such limitation is a requirement under applicable law (including any case law) at that point in time and that such limitation shall not free the Swiss Note Guarantor from its
obligations in excess thereof, but merely postpone the performance date until such time as performance is permitted notwithstanding such limitation. 
 (c) For the purpose of this clause, “Free Reserves Available for Distribution” means an amount equal to the maximal amount in which the relevant Swiss Note Guarantor can make a dividend payment
to its shareholder(s) (being the balance sheet profit and any freely disposable reserves available for this purpose, in each case in accordance with applicable Swiss law). 
 (d) As soon as possible after having been requested to discharge a Restricted Obligation, the Swiss Note Guarantor shall, if it cannot discharge the full amount of the Restricted Obligations, provide the
Trustee with an interim statutory balance sheet audited by the statutory auditors of the Swiss Note Guarantor setting out the Free Reserves Available for Distribution and, immediately thereafter, pay the amount corresponding to the Free Reserves
Available for Distribution to the Trustee (save to the extent provided below). 
 (e) In respect of the Restricted Obligations,
the Swiss Note Guarantor shall: 
  

	 	(i)	if and to the extent required by applicable law in force at the relevant time: 


 

	 	(A)	subject to any applicable double taxation treaties, deduct Swiss withholding tax at the rate of 35 percent (or such other rate as is in force at that time) from any
payment made by it; 

  

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


  
 4 









	 	(C)	notify and provide evidence to the Trustee that the Swiss withholding tax has been paid to the Swiss Federal Tax Administration; 


 

	 	(ii)	to the extent such deduction is made, not be required to make a gross-up, indemnify or otherwise hold harmless the Trustee or the Holders for the deduction of the Swiss
withholding tax notwithstanding anything to the contrary contained in the Indenture, the Notes or any other agreement, unless grossing up is permitted under the laws of Switzerland then in force and provided that this should not in any way limit any
obligations of any non-Swiss Note Guarantors under the Indenture, the Notes or any other agreement to indemnify the Trustee or the Holders in respect of the deduction of the Swiss withholding tax. The Swiss Note Guarantor shall use all reasonable
efforts to procure that any person which is entitled to a full or partial refund of any Swiss withholding tax paid pursuant to paragraph (a) above will, as soon as possible after the deduction of the Swiss withholding tax: (y) request a
refund of the Swiss withholding tax under any applicable law (including double taxation treaties) and (z) pay to the Trustee upon receipt any amount so refunded. 


(f) The Swiss Note Guarantor will take, and cause to be taken, all and any other action, including, without limitation, the passing of
any shareholders’ resolutions to approve any payment or other performance under the Indenture and the Notes and the receipt of any confirmations from the Swiss Note Guarantor’s auditors, whether following a request to discharge a
Restricted Obligation or which may be required as a matter of mandatory Swiss law in force at the time it is required to make a payment or perform other obligations under the Indenture, the Notes or any other agreement in order to allow a prompt
payment or performance of other obligations under the Indenture or the Notes. 
 (g) If the enforcement of the Restricted
Obligations would be limited due to the effects referred to in this Section 3.03 and if any asset of the Swiss Note Guarantor has a book value that is less than its market value (an “Undervalued Asset”), the Swiss Note
Guarantor shall, to the extent permitted by applicable law and its accounting standards (i) write up the book value of such Undervalued Asset such that its balance sheet reflects a book value that is equal to the market value of such
Undervalued Asset, and (ii) make reasonable efforts to realize the Undervalued Asset for a sum which is at least equal to the market value of such asset. Without prejudice to the rights of the Trustee and the Holders under the Indenture, the
Notes or any other agreement, the Swiss Note Guarantor will only be required to realize an Undervalued Asset if such asset is not necessary for the Swiss Note Guarantor’s business (nicht betriebsnotwendig).
