| | c. | Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S.
dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee, acting on behalf of and for the benefit of
the Holders, could purchase U.S. dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligations of the Issuers and each Note Guarantor in respect of any sum due from them
to the Trustee shall, notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by the Trustee of any sum adjudged to be so due in such other currency, on which (and only
to the extent that) the Trustee may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to the Trustee and the Holders hereunder, the
Issuers and each Note Guarantor agree, as a separate obligation and notwithstanding any such judgment, to indemnify the Trustee and the Holders against such loss. If the U.S. dollars so purchased are greater than the sum originally due to the
Trustee and the Holders hereunder, the Trustee agrees to deliver to the Issuers and the Note Guarantors (but without duplication) an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to the Trustee and the
Holders hereunder.
