and to become a Lender under the Amended Credit Agreement, (ii) it meets all the
requirements to be an assignee under Section 8.08(b)(iii), (v) and (vi) of the

Assumptions without the payment of any related assignment fee, and, except for
any requested replacement promissory notes to be provided to the Assignor
Lenders and Assignee Lenders in the principal amounts of their respective
Commitments (or, if less, in the case of any such promissory note payable by a
Borrower, such Assignor Lender’s or Assignee Lender’s pro rata share (based on
the Commitments of all Lenders) of such Borrower’s Borrower Sublimit), no other
documents or instruments shall be, or shall be required to be, executed in
connection with such purchases and assignments (all of which are hereby waived).

themselves, through the Administrative Agent, as the Administrative Agent may
direct (after giving effect to any netting effected by the Administrative Agent)
