Guarantees (a) Prior to the Closing, Seller and Purchaser shall, and shall cause their respective Affiliates to, reasonably cooperate and shall use their respective reasonable best efforts to, effective as of the Closing, terminate or cause to be terminated, or cause Purchaser or one of its Affiliates to be substituted in all respects for Seller or any of its Affiliates (collectively, the “Seller Guarantors”) in respect of all liabilities and obligations of the Seller Guarantors under, any Seller Guarantee listed on Schedule 5.7 to this Agreement. (b) With respect to any Seller Guarantees listed on Schedule 5.7 to this Agreement that are not terminated or for which Purchaser or one of its Affiliates has not been substituted in all respects for the applicable Seller Guarantor(s) as provided in Section 5.7(a), (i) Seller and Purchaser shall, and shall cause their respective Affiliates to, continue to reasonably cooperate and use their respective reasonable best efforts to terminate, or cause Purchaser or one of its Affiliates to be substituted in all respects for the Seller Guarantors in respect of, all obligations and liabilities under any such Seller Guarantees, and (ii) Purchaser shall (A) obtain and maintain in effect (including through any replacement letters of credit) one or more letters of credit, in a form and substance reasonably satisfactory to Seller and effective as of the Closing, to backstop any of the Seller Guarantors’ liabilities or obligations under any such Seller Guarantee, and (B) not, and shall not permit any of its Affiliates to, (1) renew or extend the term of, (2) increase its obligations under, (3) transfer to another third party, or (4) amend in any manner, except as contemplated pursuant to clause (i) of this Section 5.7(b) or otherwise required by this Agreement, any Contract or other obligation for which Seller or any of its Affiliates (including any Seller Guarantor) is or would reasonably be expected to be liable under any such Seller Guarantee. (c) To the extent that any Seller Guarantor has performance obligations or any other Liability under or related to any Seller Guarantee listed on Schedule 5.7 to this Agreement, in each case, if and to the extent related to the conduct of the Business or the operation of the Transferred Assets after the Closing, Purchaser shall (i) perform, pay and discharge, or cause one or more of its Affiliates to perform, pay and discharge in all respects such obligations on behalf of such Seller Guarantor or (ii) otherwise use reasonable best efforts to take such actions as reasonably requested by Seller so as to put such Seller Guarantor in the same position as if Purchaser or one or more of its Affiliates, and not such Seller Guarantor, had performed or were performing such obligations. (d) For purposes of this Section 5.7, and for the avoidance of doubt, “reasonable best efforts” shall not require Seller or Purchaser to, or to cause any of its Affiliates to, (i) make or accelerate any payment under any Indebtedness, Contract or other obligation for which a Seller Guarantor is or may be liable under any Seller Guarantee or (ii) pay any other amounts, provide other consideration or otherwise grant any accommodation to any third party.
