“(d) Indebtedness of the Borrower or any Subsidiary of the Borrower owing to the Borrower or another Subsidiary of the Borrower; provided that:

(i) in the case of Indebtedness owing to a Loan Party, such Indebtedness shall be evidenced by:

(A) one or more promissory notes or similar instruments that are pledged to the Administrative Agent for the benefit of the Secured Parties pursuant to the Pledge Agreement; or

(B) in the case of Indebtedness owing to a Loan Party by any Subsidiary of the Borrower that is organized under Luxembourg law, (x) one or more promissory notes or similar instruments that are pledged in accordance with clause (A) of this subsection or (y) one or more convertible preferred equity certificates or similar documents (such certificates and documents, “CPECs”) in which a security interest is granted to the Administrative Agent for the benefit of the Secured Parties pursuant to a pledge or security agreement in form and substance reasonably satisfactory to the Administrative Agent; provided that (1) if any such CPECs are, or are converted into, Equity Interests that constitute Voting Stock (as defined in the Pledge Agreement) of any First-Tier Foreign Subsidiary, any security interest granted to the Administrative Agent for the benefit of the Secured Parties in such CPECs shall be automatically limited to Voting Stock of such First-Tier Foreign Subsidiary representing not more than 65% of the total Voting Power (as defined in the Pledge Agreement) of all outstanding Voting Stock of such First-Tier Foreign Subsidiary, and (2) if the Administrative Agent shall require that such security interest in any CPEC be created pursuant to a pledge or security agreement that is governed by Luxembourg law, the Borrower shall be given a period of sixty (60) days to comply with such requirement (or such longer period of time as the Administrative Agent in its sole discretion shall permit);

(ii) in the case of any Indebtedness owing by a Loan Party to any Subsidiary of the Borrower that is not a Loan Party, such Indebtedness shall be on terms (including subordination terms) reasonably satisfactory to the Administrative Agent; and

(iii) such Indebtedness shall be otherwise permitted under the provisions of Section 6.04;”

3    Representations. To induce the other parties hereto to enter into this Amendment, the Borrower represents and warrants that, after giving effect to each of the amendments and waivers set forth in this Amendment, (a) the representations and warranties of the Borrower and each other Loan Party contained in Article III of the Credit Agreement or any other Loan Document are true and correct on and as of the date hereof with the same effect as though made on and as of such date, except to the extent such representations and warranties specifically refer to an earlier date, in which case such representations and warranties shall be true and correct as of such earlier date, and (b) no Default has occurred and is continuing.

4    Effectiveness. This Amendment shall become effective as of the date hereof on the date when the Administrative Agent shall have received counterparts of this Amendment that, when taken together, bear the signatures of (i) the Borrower and (ii) the Required Lenders.
