Debt Instrument, Covenant Description					Mandatory prepayments are required if the outstanding revolving loans or facility letters of credit exceed the aggregate revolving credit commitments, including due to currency fluctuations if difference is greater than 105 percent, the excess loans must be repaid or facility letters of credit must be cash collateralized. Voluntary prepayments require one business day notice for floating rate loans in $1.0 or multiples thereof and three business days for euro currency rate loans in $5.0 or $1.0 multiples thereof. There is a prepayment premium with respect to the Term B Facility only. Until May 6, 2017, if there is a repricing event, where the Term B Facility is refinanced or amended to reduce the yield, there is a prepayment premium of 1.00 percent refinanced or amended. Other mandatory prepayments include incurrence of new debt outside what is allowed in the Credit Agreement, sale of certain assets beyond a de-minimis exception amount and depending on the net debt leverage, a percentage of "Excess Cash Flows" as defined in the Credit Agreement beginning with 2017 cash flows.
