STOCK REDEMPTION AGREEMENT

THIS AGREEMENT, made this 27th day of June, 1975, between P. C. DAVIDSON, of Fargo, North Dakota, hereinafter referred to as “Seller”, and SIOUX FALLS AMBULANCE, INC., a South Dakota corporation, hereinafter referred to as “Company”,

W I T N E S S E T H:

WHEREAS, Seller is the owner of twenty-two (22) shares of the issued and outstanding stock of the Company and is desirous of withdrawing from the management and ownership of the Company and wishes to sell and liquidate all of his interest therein; and

WHEREAS, Company, by action of its Board of Directors at their meeting on June 27, 1975, has agreed to purchase and redeem the Seller’s shares for the full sum of $104,760.00; and

WHEREAS, it is contemplated that this redemption shall be in complete redemption of all of the stock of “Seller” actually and constructively owned and he shall not after the date of closing have any interest whatsoever in the Company except as a creditor with respect to the unpaid purchase price of his stock,

NOW, THEREFORE, it is agreed between the parties hereto as follows:

1. Sale of Stock. Seller shall sell, and Company shall purchase and redeem twenty-two (22) shares of the common capital stock of Company now owned and held by Seller, for a total purchase price of $10,760.00.

2. Payment of Purchase Price and Loan. Company shall pay the total purchase price at the time of closing. Seller shall transfer 22 shares of the common capital stock of the Company to Company at time of closing.

3. Closing. Closing shall occur in Sioux Falls, South Dakota, on June 27, 1975.

4. Warranties of Seller. In order to induce Company to enter into this agreement, Seller warrants and represents:

A. That he owns 22 shares of the common capital stock of Company, of which 40 shares are issued and outstanding, and that his shares are free and clear of all encumbrances, and that he has the right to sell the said shares.

B. Between the date hereof and the closing, Company will not modify or reduce its authorized shares, will not consolidate or merge with any other business, will not distribute any of its assets, or pay or declare any dividends in cash or in property or in any of its shares, will not redeem any of its outstanding shares, and will not sell, mortgage, encumber or dispose of any of its property except in the regular course of its business.

5. Warranties of Company. In order to induce Seller to enter into this agreement, Company warrants and represents:

A. That it will proceed with due diligence to arrange bank financing and will make every reasonable effort to obtain such financing.

B. That Company, between the date of this agreement and closing, will not modify or change the basic operations of Company, will not encumber or dispose of any of the assets, will not make any major adjustments in salaries or enter into any leases or contracts which are not in the ordinary course of business, and will not buy or sell any major assets without the consent of Seller. However, this does not restrict Company from approaching the County of Minnehaha and the City of Sioux Falls to make adjustments in the existing subsidy contract.

6. Seller’s Withdrawal from Company. As of date of closing, Seller tenders his stock for redemption, resigns and withdraws as director, officer and employee of Company, and undertakes and agrees that he will not acquire any such interest or position for a ten-year period running from the date of closing.

7. Non-Competition. Seller agrees not to compete with Company by providing ambulance service in Sioux Falls, South Dakota, for a period of ten years from the date of this agreement, so long as company does not breach its existing contract with the City of Sioux Falls, South Dakota. Seller may compete with Company within the ten-year period only in the event that the City Commission of Sioux Falls requests his provision of ambulance service in Sioux Falls for reason of Company’s inability to provide adequate ambulance service for Sioux Falls.

This agreement shall be binding upon and shall inure to the benefit of the parties, their legal representatives and assigns.

IN WITNESS WHEREOF, the parties hereto have hereunto set their hands and official seals the day and year first above written.
