2.12.3.5 if all or any portion of such Defaulting Lender’s Letter of Credit Obligations are neither reallocated nor cash collateralized pursuant to Section 2.12.3.1 or 2.12.3.2 above, then, without prejudice to any rights or remedies of the Issuing Lender or any other Lender hereunder, all Letter of Credit Fees payable under Section 2.11.2 with respect to such Defaulting Lender’s Letter of Credit Obligations shall be payable to the Issuing Lender (and not to such Defaulting Lender) until and to the extent that such Letter of Credit Obligations are reallocated and/or cash collateralized; and

- 8 -

the Issuing Lender, as the case may be, shall have entered into arrangements with the Borrower or such Lender, satisfactory to PNC or the Issuing Lender, as the case may be, to defease any risk to it in respect of such Lender hereunder.

In the event that the Administrative Agent, the Borrower, PNC and the Issuing Lender agree in writing that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Administrative Agent will so notify the parties hereto, and the Ratable Share of the Swing Loans and Letter of Credit Obligations of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment, and on such date such Lender shall purchase at par such of the Loans of the other Lenders (other than Swing Loans) as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Ratable Share.
