In such circumstances, the amount payable on any date in euros shall be converted into U.S. Dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second business day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. Dollar/euro exchange rate published in The Wall Street Journal on or prior to the second business day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate shall be determined in the Company’s sole discretion on the basis of the most recently available market exchange rate for euros.
