with the terms and conditions set forth in this Amendment, in a principal amount equal to such Incremental Lender’s Applicable Percentage (as defined below) of the Incremental Loans to be funded on the Take Private Effective Date, but in any event, not to exceed such Incremental Lender’s Incremental Commitment set forth on Schedule I hereto.

As used herein, “Applicable Percentage” means, with respect to each Incremental Lender at any time a fraction (expressed as a percentage carried out to the ninth decimal place), the numerator of which is the amount of the Incremental Commitment of such Incremental Lender at such time and the denominator of which is the amount of the aggregate Incremental Commitments at such time.

(d) The Incremental Loans incurred pursuant to this Amendment shall be incurred using the Phase II Incremental Amount (as defined in Amendment No. 1).
