	THE CREDIT FACILITY; BORROWING PROCEDURES; INTEREST RATE; PAYMENTS; AND FEES.


		
	2.1.
	Credit Facility. So long as no Event of Default has occurred or the obligation of the Lender to advance funds under the Revolving Loans has not been extinguished, Lender may lend to CAS and CAS agrees to borrow from Lender (and to repay to Lender in accordance with the terms hereof) from time to time an aggregate principal sum equal to the principal face amount of the Revolving Note. As long as no Event of Default shall have occurred and be continuing, and subject to the further conditions and limitations contained herein and until expiration or maturity of the Revolving Loans, upon acceleration or otherwise, CAS may borrow, repay and re-borrow the Revolving Loans. If at any time the aggregate principal outstanding of Revolving Loans exceeds the principal face amount of the Revolving Note, CAS shall immediately repay to Lender, without the necessity of notice or demand from Lender, an amount not less than such excess.


All Revolving Loans made pursuant to this Supplement will be evidenced by the Revolving Note, shall be payable, as to interest, in accordance with the Revolving Note, and as to the principal, on the Revolving Note Maturity Date and will be made by deposits or transfers to CAS’s demand deposit account maintained with Lender or as otherwise directed by CAS. Although the Revolving Note shall be expressed to be payable in the full amount specified above, CAS shall be obligated to pay only the principal amount of Revolving Loans actually disbursed to or for the account of CAS, together with interest on the unpaid balance of the sums so disbursed, which remain outstanding from time to time as shown on the records of Lender.
		
	2.2.
	Borrowing Procedures. CAS shall request Revolving Loans by written notice, or by telephonic notice confirmed in writing, to Lender, not later than 2:00 p.m., Milwaukee time, on the requested Borrowing Date (which must be a Business Day). Each such request by CAS, must specify the amount of the requested Loan. In the event of any inconsistency between the telephonic notice and the written confirmation thereof, the telephonic notice shall control.


Each request for a Revolving Loan shall be irrevocable and shall constitute a certification by CAS that the borrowing conditions specified in Section 5.2 of the Master Loan Agreement and any conditions set forth in Section 3 of this Supplement will be satisfied on the specified Borrowing Date. Upon fulfillment of the applicable borrowing conditions set forth in Section 5.2 of the Master Loan Agreement and any conditions set forth in Section 3 of this Supplement, Lender shall deposit the Loan proceeds in CAS’s demand deposit account maintained with Lender or as CAS may otherwise direct in writing.
Notwithstanding anything contained herein to the contrary, in the event CAS and Lender have established a loan sweep arrangement, the terms of the documents governing such loan sweep, as applicable, shall supersede the borrowing procedures contained herein.
		
	2.3.
	Interest Rate. The unpaid principal balance of each of the Revolving Loans outstanding from time to time shall bear interest for the period commencing on the Borrowing Date of such Loan until such Loan is paid in full. The Revolving Loans shall accrue interest at a variable rate equal to the LIBOR Rate plus 3.00% per annum and such rate shall be adjusted on the 7th day of each month.


		
	2.4.
	Payments. CAS shall make the following payments on the Revolving Loans during the following periods:


		
	(a)
	Monthly Payments. Monthly payments of accrued unpaid interest only on the Revolving Loans due in arrears on the ‘7th day of each month, commencing on March 7, 2018, together with a final payment of the outstanding principal balance together with all accrued but unpaid interest together with such other amounts as shall then be due and owing from CAS to Lender under the Revolving Note due on the Revolving Note Maturity Date.


		
	(b)
	Revolving Loan Resting Period. CAS shall also make principal payments necessary to cause the total outstanding principal balance of all Revolving Loans to be zero (0) for at least thirty (30) consecutive days (the “Resting Period”) during the term of the Revolving Loans, or if the term of the Revolving Loans exceeds one (1) year, during each annual period ending on the anniversary of the date of the Revolving Loans (each a “Testing Period”). Notwithstanding the foregoing, CAS shall have no obligation to cause a Resting Period, if, at the time that a Resting Period would otherwise be required hereunder, CAS achieves a Debt Service Coverage Ratio of 1.10:1.
