1.4 Amendment to Section 11. The following new Section 11.12 is added to the end of Section 11 of the Agreement:

SECTION 11.12 Erroneous Payments.

(a) If the Agent (x) notifies a Lender or any Person (other than the Borrower) who has received funds on behalf of a Lender (any such Lender or other recipient (and each of their respective successors and assigns) , a “Payment Recipient”) that the Agent has determined in its sole discretion (whether or not after receipt of any notice under the immediately succeeding clause (b)) that any funds (as set forth in such notice from the Agent) received by such Payment Recipient from the Agent or any of its Affiliates were erroneously or mistakenly transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender or other Payment Recipient on its behalf) (any such funds, whether transmitted or received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and (y) demands in writing the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Agent pending its return or repayment as contemplated below in this Section 11.12, and such Lender shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two Business Days thereafter (or such later date as the Agent may, in its sole discretion, specify in writing), return to the Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon (except to the extent waived in writing by the Agent) in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Agent in same day funds at the greater of the Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Agent to any Payment Recipient under this clause (a) shall be conclusive, absent manifest error.

(b) Without limiting the immediately preceding clause (a), each Lender or any Person who has received funds on behalf of a Lender (and each of their respective successors and assigns), agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in this Agreement or in a notice of payment, prepayment or repayment sent by the Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Agent (or any of its Affiliates), or (z) that such Lender or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part), then in each such case:

(i) it acknowledges and agrees that (A) in the case of the immediately preceding clauses (x) or (y), an error and mistake shall be presumed to have been made (absent written confirmation from the Agent to the contrary) or (B) an error and mistake has been made (in the case of the immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and

(ii) such Lender shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one Business Day of its knowledge of the occurrence of any of the circumstances described in the immediately preceding clauses (x), (y) and (z)) notify the Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Agent pursuant to this Section 11.12(b).

For the avoidance of doubt, the failure to deliver a notice to the Agent pursuant to this Section 11.12(b) shall not have any effect on a Payment Recipient’s obligations pursuant to Section 11.12(a) or on whether or not an Erroneous Payment has been made.
