§1.        Amendments to the Credit Agreement. Subject to Section 4 below, and in reliance on the representations and warranties of the Loan Parties set forth herein, pursuant to Section 10.01 of the Credit Agreement:

(a)        Section 1.01 of the Credit Agreement is hereby amended to add the following defined terms in the appropriate alphabetical order:

““Corresponding Debt” has the meaning specified in Section 10.23.

Interests are or are required to be pledged on or after the Closing Date (a “Pledged Subsidiary”) in favor of the Administrative Agent under any Loan Document, as the case may be, may be an Unrestricted Subsidiary. As of the Closing Date, the Unrestricted Subsidiaries are set forth on Schedule 6.16. Any Subsidiary which has been designated as an Unrestricted Subsidiary pursuant to this Section 6.16 may, at any time thereafter, be redesignated as a Restricted Subsidiary by the Borrower; provided, however, that a Subsidiary that has been redesignated as a Restricted Subsidiary as provided in this sentence may not thereafter be designated or redesignated as an Unrestricted Subsidiary.”

(e)        Section 7.09 of the Credit Agreement is hereby amended and restated to read in its entirety as follows:

“      7.09    Burdensome Agreements.    Enter into any Contractual Obligation (other than this Agreement or any other Loan Document) that (a) limits the ability (i) of any Material Domestic Subsidiary, Pledged Subsidiary or SDHI to make Restricted Payments to the Borrower, any Pledgor Subsidiary or any Guarantor or to otherwise transfer property to the Borrower, any Pledgor Subsidiary or any Guarantor, (ii) of any Material Domestic Subsidiary or any Pledgor Subsidiary to Guarantee the Indebtedness of the Borrower or any Guarantor or (iii) of the Borrower, any Pledgor Subsidiary or any Material Domestic Subsidiary to create, incur, assume or suffer to exist Liens on property of such Person; provided, however, that, so long as the following do not violate Section 7.12, (A) none of the foregoing shall apply to restrictions and conditions imposed by applicable Laws (which (taken as a whole) could not reasonably be expected to have a Material Adverse Effect), (B) none of the foregoing shall apply to customary restrictions and conditions contained in agreements relating to the sale of the assets or Equity Interests permitted under Section 7.05 pending such sale, provided such restrictions and conditions apply only to the Person whose assets or Equity Interests are to be sold, (C) clauses (i) and (iii) shall not apply to restrictions or conditions imposed on specific assets which are the subject of any leases (including Capital Leases) or to customary provisions in leases (including Capital Leases) and other contracts restricting the assignment of such leases and other contracts, (D) clauses (ii) and (iii) shall not apply to the restrictions contained in the Senior Notes Indentures (as such restrictions are in effect on the date hereof) and (E) clauses (ii) and (iii) shall not apply to customary restrictions contained in the documentation relating to financings permitted hereunder, provided that such restrictions shall not restrict (x) any Loan Party’s or Material Domestic Subsidiary’s ability to grant Liens in favor of the Administrative Agent and Secured Parties (or the Administrative Agent and Secured Party’s ability to enforce such Liens) under or in connection with the Loan Documents or (y) any Loan Party’s or Material Domestic Subsidiary’s ability to guarantee the Obligations; or (b) requires the grant of a Lien to secure an obligation of such Person if a Lien is granted to secure the Obligations, other than the requirements contained in the Senior Notes Indentures (as such requirements are in effect on the date hereof).”

(f)        Section 10.02(a)(i) of the Credit Agreement is hereby amended to replace the phrase “if to the Borrower, the Guarantors” with the phrase “if to the Borrower or any other Loan Party”.

(g)        The following new Section 10.23 is hereby added to the Credit Agreement in proper numerical order:

“        10.23    Parallel Debt (Dutch Collateral Documents).    To grant the collateral security pursuant to the Collateral Documents governed by Dutch law to the Administrative Agent, each Loan Party irrevocably and unconditionally undertakes (and to the extent necessary undertakes in advance (bij voorbaat)) to pay to the Administrative Agent amounts equal to any amounts owing from time to time by such Loan Party to any Secured Party under any Loan Document as and when those amounts are due. Each Loan Party and the Administrative Agent and the other Secured Parties acknowledge that the obligations of each Loan Party under this Section 10.23 are several and are separate and independent (eigen zelfstandige verplichtingen) from, and shall not in any way limit or affect, the corresponding obligations of that Loan Party to any Secured Party under this Agreement or any other Loan Document (its “Corresponding Debt”) nor shall the amounts for which each Loan Party is liable under this Section 10.23 (its “Parallel Debt”) be limited or affected in any way by its Corresponding Debt provided that: (a) the Parallel Debt of each Loan Party shall be decreased to the extent that its Corresponding Debt has been irrevocably paid or (in the case of guarantee obligations) discharged; (b) the Corresponding Debt of each Loan Party shall be decreased to the extent that its Parallel Debt has been irrevocably paid or (in the case of guarantee obligations) discharged; and (c) the amount of the Parallel Debt of each Loan Party shall at all times be equal to the amount of its Corresponding Debt. For the purpose of this Section 10.23, the Administrative Agent acts in its own name and on behalf of itself and not as agent, representative or trustee of any other Secured Party, and its claims in respect of each Parallel Debt shall not be held in trust. The collateral security granted under the Dutch law Collateral Documents to the Administrative Agent to secure each Parallel Debt is granted to the Administrative Agent in its capacity as sole creditor of each Parallel Debt. All monies received or recovered by the Administrative Agent pursuant to this Section 10.23, and all amounts received or recovered by the Administrative Agent from or by the enforcement of any collateral security granted to secure each Parallel Debt, shall be applied in accordance with Section 8.03. Without limiting or affecting the Administrative Agent’s rights against the Loan Parties (whether under this Section 10.23 or under any other provision of the Loan Documents), each Loan Party acknowledges that: (x) nothing in this Section 10.23 shall impose any obligation on the Administrative Agent to advance any sum to any Loan Party or otherwise under any Loan Document, except in its capacity as Lender or L/C Issuer, as the case may be, pursuant to other terms of this Agreement; and (y) for the purpose of any vote taken under any Loan Document, the Administrative Agent shall not be regarded as having any participation or commitment other than those which it has in its capacity as a Lender or L/C Issuer, as the case may be. For the avoidance of doubt: (i) the Parallel Debt of each Loan Party will become due and payable (opeisbaar) at the same time its Corresponding Debt becomes due and payable; and (ii) without prejudice to this Section 10.23, a Loan Party may not repay or prepay its Parallel Debt unless directed to do so by the Administrative Agent or the collateral security is enforced by the Administrative Agent.”
