Aggregate Principal Amount The aggregate principal amount of the Senior Notes that may be authenticated and delivered under this First Supplemental Indenture shall be unlimited; provided that the Obligor complies with the provisions of this First Supplemental Indenture.
Corresponding Payment Each permanent reduction permitted pursuant to this Section shall be accompanied by a payment of principal sufficient to reduce the aggregate outstanding Revolving Credit Loans, Swingline Loans and L/C Obligations, as applicable, after such reduction to the Revolving Credit Commitment as so reduced, and if the aggregate amount of all outstanding Letters of Credit exceeds the Revolving Credit Commitment as so reduced, the Borrower shall be required to deposit Cash Collateral in a Cash Collateral account opened by the Administrative Agent in an amount equal to such excess. Such Cash Collateral shall be applied in accordance with Section 10.2(b). Any reduction of the Revolving Credit Commitment to zero shall be accompanied by payment of all outstanding Revolving Credit Loans and Swingline Loans (and furnishing of Cash Collateral satisfactory to the Administrative Agent for all L/C Obligations) and shall result in the termination of the Revolving Credit Commitment and the Swingline Commitment and the Revolving Credit Facility. If the reduction of the Revolving Credit Commitment requires the repayment of any LIBOR Rate Loan, such repayment shall be accompanied by any amount required to be paid pursuant to Section 5.9 hereof.
Amount The required additional Security shall be in an amount equal to the amount necessary to gross up fully for currently applicable federal and state income taxes the estimated Costs of Local Upgrades and Network Upgrades for which Interconnection Customer previously provided Security. Accordingly, the additional Security shall equal the amount necessary to increase the total Security provided to the amount that would be sufficient to permit the Interconnected Transmission Owner to receive and retain, after the payment of all applicable income taxes (“Current Taxes”) and taking into account the present value of future tax deductions for depreciation that would be available as a result of the anticipated payments or property transfers (the “Present Value Depreciation Amount”), an amount equal to the estimated Costs of Local Upgrades and Network Upgrades for which Interconnection Customer is responsible under the Interconnection Service Agreement. For this purpose, Current Taxes shall be computed based on the composite federal and state income tax rates applicable to the Interconnected Transmission Owner at the time the additional Security is received, determined using the highest marginal rates in effect at that time (the “Current Tax Rate”), and (ii) the Present Value Depreciation Amount shall be computed by discounting the Interconnected Transmission Owner’s anticipated tax depreciation deductions associated with such payments or property transfers by its current weighted average cost of capital.
