Increases and new Commitments created pursuant to this clause shall become effective on the date agreed by the Borrower, the Administrative Agent and the relevant Lenders and the Administrative Agent shall notify each affected Lender thereof.

4

such Permitted Acquisition, (v) each such Permitted Acquisition shall be made on a consensual (meaning, in the case of a Person to be acquired, approved by the majority in interest of the board of directors or analogous governing body of such Person) basis between the Borrower or any Domestic Subsidiaries party to such transaction, as applicable, on the one hand, and the Person or Persons being so acquired or the seller or sellers of such assets or such business, on the other hand, (vi) the purchase price (including any assumed Indebtedness) for all such Permitted Acquisitions shall not exceed $150,000,000 in the aggregate or $60,000,000 in anyone or a series of related transactions, and (vii) the business unit or Person that is the subject of such Permitted Acquisition shall be in the same or a similar line of business as the Borrower and its Subsidiaries or in a business that is related or complementary to the business of the Borrower and its Subsidiaries and (viii) substantially all of the assets acquired in such Permitted Acquisition shall be located in the North America or Western Europe.”
