This Amendment and the other Amendment Documents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4, this Amendment shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto.

(g)The Borrower agrees to pay or reimburse all reasonable out-of-pocket expenses incurred by the Administrative Agent (including the reasonable fees, charges and disbursements of counsel for the Administrative Agent), in connection with the preparation, negotiation, execution, delivery and administration of this Amendment and the other Amendment Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated).
