7 -

Recipient ”) that the Agent has determined in its sole discretion (whether or not after receipt of any notice under Section 12.26(b)) that any funds received by such Payment Recipient from the Agent or any of its Affiliates were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender, Secured Party or other Payment Recipient on its behalf) (any such funds, whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “ Erroneous Payment ”) and demands the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Agent, and such Lender or other Secured Party 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, 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 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 (x) in respect of an Erroneous Payment in Canadian Dollars or any other currency at a fluctuating rate per annum equal to the overnight rate at which Canadian Dollars or funds in the currency of such Erroneous Payment, as the case may be, may be borrowed by the Agent in the interbank market in an amount comparable to such Erroneous Payment (as determined by the Agent); and (y) 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 Section 12.26(a) shall be conclusive, absent manifest error.

(b) Without limiting Section 12.26(a), each Lender and each other Secured Party hereby further agrees that if it (or any other Payment Recipient on its behalf) 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 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, other Secured Party or other such Payment Recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part) in each case:
(i) (A) in the case of immediately preceding clauses (x) or (y), an error shall be presumed to have been made (absent written confirmation from the Agent to the contrary) or (B) an error has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and
(ii) such Lender or other Secured Party 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 such error) notify the Agent of its receipt of such payment, prepayment or repayment, the
8 -

details thereof (in reasonable detail) and that it is so notifying the Agent pursuant to this Section 12.26(b).

(c) Each Lender and each other Secured Party hereby authorizes the Agent to set off, net and apply any and all amounts at any time owing to such Lender or other Secured Party under any Loan Document, or otherwise payable or distributable by the Agent to such Lender or other Secured Party from any source, against any amount due to the Agent under Section 12.26(a) or under the indemnification provisions of this Agreement.
(d) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Agent for any reason, after demand therefor by the Agent in accordance with immediately preceding clause (a), from any Lender or other Secured Party that has received such Erroneous Payment (or portion thereof) (and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf) (such unrecovered amount, an “ Erroneous Payment Return Deficiency ”), upon the Agent’s notice to such Lender or other Secured Party at any time, (i) such Lender or other Secured Party shall be deemed to have assigned a portion of its Applicable Percentage of the Lender Outstandings (the “ Assigned Outstandings ”) (but not its Commitment) in the currency in which such Erroneous Payment was made in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Agent may specify) (such assignment of the Assigned Outstandings (but not Commitments), the “ Erroneous Payment Deficiency Assignment ”) at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Agent in such instance), and is hereby (together with the Borrower) deemed to execute and deliver an Assignment and Assumption (or, to the extent applicable, an agreement incorporating an Assignment and Assumption) with respect to such Erroneous Payment Deficiency Assignment, (ii) the Agent as the assignee Lender shall be deemed to acquire the Erroneous Payment Deficiency Assignment and (iii) upon such deemed acquisition, the Agent as the assignee Lender shall become a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender, hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitments which shall survive as to such assigning Lender. The Agent may, in its discretion, sell any Assigned Outstandings and upon receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender shall be reduced by the net proceeds of the sale of such Assigned Outstandings (or portion thereof), and the Agent shall retain all other rights, remedies and claims against such Lender (and/or against any recipient that receives funds on its respective behalf). For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitments of any Lender and such Commitments shall remain available in accordance with the terms of this Agreement. In addition, each party hereto agrees that, except to the extent that the Agent has sold any Assigned Outstandings (or portion thereof) acquired pursuant to an Erroneous Payment Deficiency Assignment, and irrespective of whether the Agent may be equitably subrogated, the Agent shall be contractually subrogated to all the rights and interests of the applicable Lender under the Loan Documents with respect to each Erroneous Payment Return Deficiency.

- (f) To the extent permitted by Applicable Law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Agent for the return of any Erroneous Payment received, including, without limitation, waiver of any defense based on “discharge for value” or any similar doctrine.
- (g) Each party’s obligations, agreements and waivers under this Section 12.26 shall survive the resignation or replacement of the Agent, the termination of the Commitments and/or the repayment, satisfaction or discharge of all Lender Outstandings (or any portion thereof) under any Loan Document.”
