|Address of Real Property: |  | SEC 15, T106N, R12W EYOTA, MN
55934

2. LENDERS MORTGAGE AND CONDITION PRECEDENT. Borrower has requested a $ 250,000.00 loan from
Lender to be secured by a Mortgage on the Property from Mortgagor in favor of Lender; Lender is only willing to make the loan on condition that Creditors Mortgage described in paragraph 1 be subordinated to the Mortgage to be executed in favor
of Lender.

Lenders Mortgage will also secure, without limitation, such additional sums as Lender may advance under the provisions as
to future advances, additional sums for the purpose of curing any of Borrowers defaults, interest on principal, and attorneys fees and costs incurred by Lender in any proceedings arising out of or in connection with Lenders
Mortgage, Including proceedings to enforce or foreclose it.

3. SUBORDINATION OF CREDITORS MORTGAGE. Creditor agrees that its
Mortgage and all of Creditors rights thereunder shall at all times be inferior and subordinate to the Lenders Mortgage and Lenders rights in the Property.

4. PRIORITY OF SECURITY INTERESTS. The priority of the Mortgages belonging to Creditor and Lender in the Property will be governed by this Agreement and
not by the time or order in which the Mortgages were created or perfected.

5. WAIVER OF LIMITATIONS. Creditor waives any obligation of
Lender to provide Creditor with notice of additional advances or loans, notice of default, notice of acceleration of debt, notice of demand for payment or notice of repossession and the right of Creditor to require Lender to marshall any collateral.
In addition, Lender may take or refrain from taking any action (including, but not limited to, making additional advances or loans) with respect to Borrower, any guarantor, or any collateral without notice to or the consent of Creditor and without
affecting any of Lenders rights under this Agreement.

6. DOCUMENTATION AND NON-INTERFERENCE. Creditor will not prevent, hinder or
delay Lender from enforcing its Mortgage. Creditor will execute and deliver to Lender such additional documents or other instruments as the Lender may deem necessary to carry out this Agreement. The Creditor will not exercise any collection rights
with respect to the Property, will not take possession of, sell or dispose of, or otherwise deal with, the Property, and will not exercise or enforce any right or remedy which may be available to the undersigned with respect to the Property upon
default, without prior written consent of Lender, which shall not be unreasonably withheld.



---

7. TERMINATION. This Agreement will remain in full force and effect now and forever, despite the
commencement of any federal or state bankruptcy, insolvency, receivership, liquidation or reorganization proceeding.

8. EFFECT ON BORROWER
AND THIRD PARTIES. This Agreement will not affect the enforceability and priority of Creditors and Lenders Mortgage on the Property and rights against the Borrower, Mortgagor, or any third party except as set forth herein.

9. REPRESENTATIONS AND WARRANTIES. Creditor represents and warrants to Lender that:

Agreement shall be binding upon and inure to the benefit of Creditor and Lender and their respective successors, assigns, trustees, receivers, administrators, personal representatives, legatees, and devisees.
