Revolving Credit Line Promissory Note dated June 14, 2017, between Heartland Financial USA, Inc. and Bankers Trust Company

PROMISE TO PAY. Heartland Financial USA, Inc. ("Borrower") promises to pay to Bankers Trust Company ("lender"), or order, in lawful money of the United States of America, the principal amount of Twenty-five Million & 00/100 Dollars ($25,000,000.00) or so much as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance. Interest shall be calculated from the date of each advance until repayment of each advance.

VARIABLE INTEREST RATE. The interest rate on this loan is subject to change from time to time based on changes in an independent index which is the 30-Day London Interbank Offered Rate (LIBOR) as published in the Wall Street Journal which may or may not necessarily reflect the rate Lender charges to its other customers which may be lower (the "Index"). The Index is not necessarily the lowest rate charged by Lender on its loans. If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower. Lender will tell Borrower the current Index rate upon Borrower's request. The interest rate change will not occur more often than each first day of the month. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 0.993% per annum. Interest on the unpaid principal balance of this loan will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 2.750 percentage points over the Index, resulting in an initial rate of 3.743% per annum based on a year of 360 days. NOTICE: Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked "paid in full", "without recourse", or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender's rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes " payment in full" of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: Bankers Trust Company, 453 7th Street, P.O. Box 897, Des Moines, lA 50304-0897.

LATE CHARGE. If a payment is 11 days or more late, Borrower will be charged 5.000% of the unpaid portion of the regularly scheduled payment or $50.00, whichever is greater.

INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final maturity, the interest rate on this Note shall be increased to 21 .000% per annum based on a year of 360 days. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.
