13

of the applicable Acceptable Credit Provider, the Collateral Agent shall draw on the Component A Letter of Credit in an amount equal to the undrawn face amount of the Component A Letter of Credit and shall deposit the proceeds of such drawing into the applicable subaccount of the relevant Letter of Credit Accounts (for application in accordance with the terms of this Security Deposit Agreement).

If at any time after the delivery of a Facility Lessee Provided Letter of Credit the amount the Collateral Agent is then directed to transfer from such subaccount of the Equity Account pursuant to the terms of this Security Deposit Agreement exceeds cash then on deposit in such subaccount of the Equity Account, as applicable (such excess amount, the "Facility Lessee Provided Shortfall Amount"), then the Collateral Agent shall draw on the Facility Lessee Provided Letter of Credit in an amount equal to the lesser of the Facility Lessee Provided Shortfall Amount and the undrawn face amount of the Facility Lessee Provided Letter of Credit and shall deposit the proceeds of such drawing into such subaccount of the Equity Account, as required (for application in accordance with the terms of this Security Deposit Agreement). If pursuant to the terms thereof the Facility Lessee Provided Letter of Credit becomes drawable as a result of the failure of such Facility Lessee Provided Letter of Credit to be extended or failure to provide a replacement letter of credit within 30 days of a downgrade of the applicable Acceptable Credit Provider, the Collateral Agent shall draw on the Facility Lessee Provided Letter of Credit in an amount equal to the undrawn face amount of the Facility Lessee Provided Letter of Credit and shall deposit the proceeds of such drawing into such applicable subaccount of the Equity Account or in such applicable subaccount of the Equity Account (for application in accordance with the terms of this Security Deposit Agreement).
