“So long as any Lender shall have any Commitment hereunder, any Loan or other Obligation hereunder shall remain unpaid or unsatisfied (other than contingent Obligations to the extent no claim giving rise thereto has been asserted), the Company shall not (excluding Sections 7.01 and 7.05 which, for the avoidance of doubt, shall not apply to the Company in any respect), nor shall it permit any Subsidiary to, directly or indirectly:”

Each party hereto acknowledges that the amendment set forth in this Amendment Letter is limited to the extent specifically set forth above and shall in no way serve to amend, or waive compliance with, any other terms, covenants or provisions of the Credit Agreement or any other Loan Document, or any obligations of the Company or any Borrower, other than as expressly set forth above.

The effectiveness of this Amendment Letter and the amendment provided herein is subject to the Administrative Agent having received original counterparts of this Amendment Letter, duly executed by the Company, the Borrowers and the Administrative Agent.
