The Borrower shall pay promptly when billed all reasonable out-of-pocket expenses of each of the Lender Parties and the Administrative Agent (including, but not limited to, reasonable fees, charges and disbursements of counsel to each of the Lender Parties and the Administrative Agent) incident to this Variance. 4. Execution in Counterparts. This Variance may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which shall be deemed to be an original, and all of which taken together shall constitute one and the same agreement, regardless of whether or not the execution by all parties shall appear on any single counterpart.
