        7.          Upon the occurrence and at any time during the continuance or existence of any Event of Default, Bank may give notice to Company declaring all outstanding Liabilities to be due and
payable, whereupon all such Liabilities then outstanding shall immediately become due and payable, without further notice or demand, and any commitment or obligation, if any, on the part of Bank to make loans or otherwise extend credit to or in favor of
Company shall immediately terminate; provided, however, upon the occurrence of any Event of Default set forth in sub-Section 6(f) hereof, the Liabilities shall immediately and automatically become due and payable and any commitment of obligation of Bank to make loans or extend
credit to or in favor of Company shall immediately and automatically terminate, in each case, without any necessity of notice or demand, each of which is hereby expressly waived by Company. In addition to the foregoing, upon the occurrence and at any time
during the continuance or existence of any Event of Default hereunder, Bank may exercise any and all rights and remedies available to it as a result thereof, whether by agreement, by law, or otherwise.

        8.          No forbearance on the part of the Bank in enforcing any of its rights or remedies under this Agreement or any other Loan Document, nor any renewal, extension or rearrangement of any
payment or covenant to be made or performed by Company hereunder or any such other Loan Document, shall constitute a waiver of any of the terms of this Agreement or such Loan Document or of any such right or remedy.

        9.          This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Michigan.

        10.          All covenants, agreements, representations and warranties by or on behalf of Company made in connection with this Agreement and any other Loan Documents shall survive the borrowing
hereunder or thereunder and shall be deemed to have been relied upon by Bank. All statements contained in any certificate or other document delivered to Bank at any time by or on behalf of Company pursuant hereto shall constitute representations and
warranties by Company.

        11.          This Agreement shall inure to the benefit of and shall be binding upon the parties hereto and their respective successors and assigns; provided, however, that Company
shall not assign or transfer any of its rights or obligations hereunder or otherwise in respect of any of the Liabilities without the prior written consent of Bank.

        12.          COMPANY AND BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO
CONSULT) WITH COUNSEL OF THEIR CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVE ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE
LIABILITIES.
