“13.27 Cure. If the Company, the Administrative Agents, the Letter of Credit Issuer and the Swingline Lenders agree in writing in their discretion that a Lender that is a Defaulting Lender or a Potential Defaulting Lender should no longer be deemed to be a Defaulting Lender or Potential Defaulting Lender, as the case may be, the Administrative Agents will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any amounts then held in the segregated account referred to in Section 13.24 (Reallocation of Defaulting Lender Commitment, Etc)), such Lender will, to the extent applicable, purchase such portion of outstanding Loans of the other Lenders and/or make such other adjustments as the Administrative Agents may determine to be necessary to cause the Revolving Credit Exposure, Letter of Credit Exposure and Swingline Exposure of the Lenders to be on a pro rata basis in accordance with their respective Commitments, whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender and will be a Non-Defaulting Lender (and such Revolving Credit Exposure, Letter of Credit Exposure and Swingline Exposure of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while such Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender or Potential Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender or Potential Defaulting Lender.”
