Obligation to Mitigate Each Lender (which term shall include Issuing Bank for purposes of this Section 2.21) agrees that, as promptly as practicable after the officer of such Lender responsible for administering its Loans or Letters of Credit, as the case may be, becomes aware of the occurrence of an event or the existence of a condition that would cause such Lender to become an Affected Lender or that would entitle such Lender to receive payments under Section 2.18, 2.19 or 2.20, it will, to the extent not inconsistent with the internal policies of such Lender and any applicable legal or regulatory restrictions, use reasonable efforts to (a) make, issue, fund or maintain its Credit Extensions, including any Affected Loans, through another office of such Lender, or (b) take such other measures as such Lender may deem reasonable, if as a result thereof the circumstances which would cause such Lender to be an Affected Lender would cease to exist or the additional amounts which would otherwise be required to be paid to such Lender pursuant to Section 2.18, 2.19 or 2.20 would be materially reduced and if, as determined by such Lender in its sole discretion, the making, issuing, funding or maintaining of such Revolving Commitments, Loans or Letters of Credit through such other office or in accordance with such other measures, as the case may be, would not otherwise adversely affect such Revolving Commitments, Loans or Letters of Credit or the interests of such Lender; provided, such Lender will not be obligated to utilize such other office or take such other measures pursuant to this Section 2.21 unless Borrower agrees to pay all reasonable incremental expenses incurred by such Lender as a result of utilizing such other office or take such other measures as described above. A certificate as to the amount of any such expenses payable by Borrower pursuant to this Section 2.21 (setting forth in reasonable detail the basis for requesting such amount) submitted by such Lender to Borrower (with a copy to Administrative Agent) shall be conclusive absent manifest error.
