        1.       Authorization of Series C Notes. The Company will authorize the issuance and sale of $50,000,000 aggregate principal amount of its 6.41% Senior Notes, Series C, due September 2, 2015 (the “Series C Notes”), to be dated the date of issue, to bear interest from such date at the rate of 6.41% per annum, payable semi-annually, on the 2nd day of each March and September in each year (commencing March 4, 2009) and at maturity and to bear interest on overdue principal (including any overdue prepayment of principal) and premium, if any, and (to the extent legally enforceable) on any overdue installment of interest at the rate per annum from time to time equal to the greater of (i) 8.41% or (ii) 2% over the rate of interest publicly announced by U.S. Bank National Association from time to time in Milwaukee, Wisconsin as its “base” or “prime” rate.

        8.       Representations and Warranties of the Company. With respect to each of the representations and warranties contained in Section 5 of the Agreement, the Company represents and warrants to the Series C Purchasers that, as of the date hereof, such representations and warranties are true and correct (A) except that all references to “Purchaser” therein shall be deemed to refer to the Series C Purchasers hereunder, all references to “this Agreement” shall be deemed to refer to the Original Agreement as supplemented by this Series C Terms Agreement, and all references to “Notes” or “Series A Notes” therein shall be deemed to refer to the Series C Notes, and (B) except for changes to such representations and warranties or the Schedules referred to therein, which changes are set forth in the attached Exhibit A.

        9.       Required Prepayments. On September 2, 2011 and on each September 2 thereafter to and including September 2, 2014 the Company will prepay $10,000,000 principal amount (or such lesser principal amount as shall then be outstanding) of the Series C Notes at par and without payment of the Make-Whole Amount or any premium, provided that upon any partial prepayment of the Series C Notes pursuant to Section 8.2 or Section 8.7 of the Agreement or purchase of the Series C Notes permitted by Section 8.5 of the Agreement, the principal amount of each required prepayment of the Series C Notes becoming due under this Section 9 of this Series C Terms Agreement on and after the date of such prepayment or purchase shall be reduced in the same proportion as the aggregate unpaid principal amount of the Series C Notes is reduced as a result of such prepayment or purchase. The principal amount of the Series C Notes to be prepaid pursuant to this Section 9 shall be allocated among all of the Series C Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment.

        10.       Make-Whole Amount for the Series C Notes. As used in this Series C Terms Agreement and the Agreement with respect to any Series C Note, the term “Make-Whole Amount” means, solely with respect to such Series C Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Series C Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount for any Series C Note, the following terms have the following meanings:

“Called Principal” means, with respect to any Series C Note, the principal of such Series C Note that is to be prepaid pursuant to Section 8.2 of the Agreement or has become or is declared to be immediately due and payable pursuant to Section 12.1 of the Agreement, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Series C Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Series C Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Series C Note, .50% over the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets (“Bloomberg”) or, if Page PX1 (or its successor screen on Bloomberg) is unavailable, the Telerate Access Service screen which corresponds most closely to Page PX1 for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury ▇▇▇▇ quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than the Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than the Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Series C Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Series C Note, all payments of such Called Principal of such Series and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Series C Notes of such Series, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 of the Agreement or Section 12.1 of the Agreement.
