obligations, covenants or agreements contained in the Credit Agreement or any
other provision of the Credit Agreement or any other Loan Document, all of which
are ratified and affirmed in all respects and shall continue in full force and
effect. The parties hereto expressly acknowledge that it is not their intention
that this Amendment or any of the other Loan Documents executed or delivered
pursuant hereto constitute a novation of any of the obligations, covenants or
agreements contained in the Credit Agreement or any other Loan Document, but
rather constitute a modification thereof pursuant to the terms contained herein.
This Amendment constitutes a Loan Document.
