6. Reference to Credit Agreement. Upon the effectiveness of this Amendment, each reference in the Credit Agreement or any other Loan Document to “this Agreement,” “hereunder,” or words of like or similar import shall mean and be reference to the Credit Agreement, as amended and modified by this Amendment.

ANY DISPUTE BETWEEN ANY BORROWER AND THE ADMINISTRATIVE AGENT OR ANY LENDER ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH, THIS AMENDMENT, THE CREDIT AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED IN ACCORDANCE WITH THE INTERNAL LAWS (INCLUDING §735 ILCS 105/5-1 ET SEQ.
