Principal Amount: $500,000.00 Date of Note: February 15, 2013

PROMISE TO PAY. PROUROCARE MEDICAL. INC ("Borrower”) promises to pay to Crown Bank ("Lender”), or order. in lawful money of the United States of America, the principal amount of Five Hundred Thousand & 00/100 Dollars ($500.000.00) together with interest on the unpaid principal balance from February 15. 2013, until paid in full.

PAYMENT. Borrower will pay this loan in full immediately upon Lender's demand. If no demand is made, subject to any payment changes resulting from changes in the Index. Borrower will pay this loan in accordance with the following payment schedule:

11 INTEREST ONLY PAYMENTS BEGINNING MARCH 15. 2013 AND CONTINUING AT MONTHLY TIME INTERVALS THEREAFTER. A PRINCIPAL PAYMENT IN THE AMOUNT OF $50.000.00 IS DUE AND PAYABLE JANUARY 15. 2014. A FINAL PAYMENT OF ANY UNPAID PRINCIPAL PLUS ACCRUED INTEREST IS DUE AND PAYABLE FEBRUARY 15, 2014.

Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any late charges; and then to any unpaid collection costs. Borrower will pay Lender at Lender's address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes in an index which is Lender's Prime Rate (the "Index"'). This is the rate Lender charges, or would charge, on 90-day unsecured loans to the most creditworthy corporate customers. This rate may or may not be the lowest rate available from Lender at any given time. Lender will tell Borrower the current Index rate upon Borrower's request. The interest rate change will not occur more often than each day. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 3.250% per annum. Interest on the unpaid principal balance of this Note will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 1.000 percentage point over the Index, rounded up to the nearest 0.001 percent, adjusted if necessary for any minimum and maximum rate limitations described below, resulting in an initial rate of 6.000% per annum based on a year of 360 days. NOTICE: Under no circumstances will the interest rate on this Note be less than 6.000% per annum or more than the maximum rate allowed by applicable law. Whenever increases occur in the interest rate, Lender, at its option, may do one or more of the following: (A) increase Borrower's payments to ensure Borrower's loan will payoff by its original final maturity date. (B) increase Borrower's payments to cover accruing interest. (C) increase the number of Borrower's payments, and (D) continue Borrower's payments at the same amount and increase Borrower's final payment.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method. This calculation method results in a higher effective interest rate than the numeric interest rate stated in this Note.

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 under the payment schedule. Rather, early payments will reduce the principal balance due and may result in Borrower's making fewer payments. 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: Crown Bank, Edina Office. 6600 France Avenue South Suite 125 Edina. MN 55435.

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.

INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final maturity, the interest rate on this Note shall be increased by adding an additional 2.000 percentage point margin ("Default Rate Margin"). The Default Rate Margin shall also apply to each succeeding interest rate change that would have applied had there been no default. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.
