“Section 8.03 Elk River.

(a) Landlord and Tenant acknowledge and agree that (i) a portion of what is commonly referred to as Building 7 (including a conveyor belt, shelter, intake and silo) on that certain Demised Property located at 1340 6^th Street, in Elk River, Minnesota (the “Elk River Property”), encroaches onto a property contiguous with the Elk River Property (the “Elk River Encroachment”, and such contiguous property, the “Neighboring Property”), which Elk River Encroachment is depicted on that certain survey of the Elk River Property, dated as of February 2, 2016, prepared by Ulteig Engineers, Inc., (ii) Landlord has an owner’s policy of title insurance issued by Stewart, which provides Landlord with insurance coverage for certain losses Landlord may incur as a result of Building 7 encroaching onto the Neighboring Property (the “Elk River Title Policy”), and (iii) if, at any time during the Lease Term, a third-party asserts its rights in and to the Neighboring Property, then either (a) if, as a result thereof, Building 7 must be relocated onto the Elk River Property, then Landlord shall file a claim against Stewart under its Elk River Title Policy upon receipt of any reasonable documentation that Landlord may need to receive from Tenant in order to file such claim (the “Elk River Supporting Documentation”), and Tenant shall move Building 7 onto the Elk River Property at Tenant’s sole cost and expense, subject to Tenant receiving any title insurance proceeds (or reimbursement from Landlord) due to Tenant as set forth herein; provided, that Landlord shall not be required to reimburse such costs in excess of the title insurance coverage amount that Landlord actually obtained under the Elk River Title Insurance Policy or (b) if such third-party agrees to permit Building 7 to perpetually remain on the Neighboring Property, subject to payment of a reasonable sum delivered to such third party as consideration for permitting Building 7 to perpetually remain on the Neighboring Property, such that, upon payment of such sum Building 7 will no longer be deemed to be an encroachment upon the Neighboring Property, then Tenant shall pay such sum to such third party and Landlord, Tenant and such third-party shall enter into an agreement, reasonably acceptable to each party thereto, permitting Building 7 to perpetually remain on the Neighboring Property. It being the intention of Landlord and Tenant that (y) if Building 7 must be moved onto the Elk River Property, then all proceeds received by Landlord resulting from a successful claim against Stewart under the Elk River Title Policy in connection with the Elk River Encroachment shall be promptly delivered to Tenant to cover any and all costs incurred by Tenant in connection with Tenant’s relocation of Building 7 pursuant to the terms of this Section 8.03, and any excess Elk River Title

2

Policy insurance proceeds shall be retained by Landlord and (z) if Building 7 is permitted to remain on the Neighboring Property subject only to such third-party receiving a reasonable sum in exchange for permitting Building 7 to remain on the Neighboring Property, then Tenant shall be responsible for payment of such sum, without deduction or offset against Rent or any reimbursement thereof from Landlord.” Notwithstanding the foregoing, if Landlord fails to file a claim under clause (a) above within thirty (30) days after receipt of the Elk River Supporting Documentation and Tenant’s completion of the relocation of Building 7, then Tenant shall provide notice of such failure to Landlord (the “Elk River Notice”). If Landlord does not cure such failure by instituting a claim under its Elk River Title Insurance Policy, as required by clause (a) above, within fifteen (15) days after receipt of the Elk River Notice, then Tenant shall provide Landlord with a reasonably detailed invoice for all reasonable, actual out-of-pocket costs incurred by Tenant in connection with Tenant’s relocation of Building 7 (the “Elk River Invoice”), pursuant to the terms hereof, and Landlord shall reimburse Tenant for such costs within thirty (30) days after receipt of the Elk River Invoice; provided, that Landlord shall not be required to reimburse such costs in excess of the title insurance coverage amount that Landlord obtained under the Elk River Title Insurance Policy.”

(e) the following shall be added to the Original Lease as a new Section 8.03(b):

“(b) Landlord and Tenant acknowledge and agree that as of the date hereof, certain portions of the Elk River Property (including, but not limited to, that portion subject to the Elk River Encroachment), are not owned in fee by either Landlord or Tenant, which portions are more specifically set forth on Exhibit I attached hereto and made a part hereof (collectively, the “Remaining Elk River Property”), but are instead owned in fee, either directly or by operation of law, by the City of Elk River (the “City”) or a third party, and, due to an oversight by the City, were not deeded from the City to the fee owner of the remaining portions, of the Elk River Property prior to the date hereof. The City is currently working to rectify this situation, and Tenant hereby covenants that if all or any portion of the Remaining Elk River Property is either deeded by the City to Tenant (as the prior fee owner of the Elk River Property) or Tenant is deemed to be the fee owner of all or any portion of the Remaining Elk River Property through a successful quite title action, then Tenant shall promptly transfer all or such portion of the Remaining Elk River Property to Landlord by executing a deed substantially similar to the deed received by Tenant conveying such Remaining Elk River Property (or applicable portion thereof) to Landlord which deed shall be in a form

3

sufficient for such deed to be recorded in the applicable real property records where the Elk River Property is located, all to be done at Tenant’s sole cost and expense. Tenant shall use commercially reasonable best efforts to work with the City or any third-party holder of ownership interests in the Remaining Elk River Property, including commencing any litigation or other legal proceedings and diligently pursuing same and making any reasonable payment required by either the City or any such third-party (such reasonable payment, being up to the fair market value of the Remaining Elk River Property), in cooperation with Landlord, to permit Landlord to acquire fee simple title to the Remaining Elk River Property no later than the one (1) year anniversary of the Commencement Date; provided, however, that Landlord and Tenant acknowledge and agree that while Tenant may take the forgoing actions, Landlord, as the owner of the Elk River Property, will be the named litigant and the signatory on any such legal proceedings and/or documents and must reasonably cooperate with Tenant’s efforts in order for the Remaining Elk River Property to be transferred in fee to Landlord during such one (1) year period. At such time as Landlord owns fee simple title to the Remaining Elk River Property, (i) the Remaining Elk River Property shall automatically be deemed part of the Elk River Property, and upon the request of Landlord or Tenant, as the case may be, the parties shall enter into an amendment to this Lease to memorialize the same and account for any encumbrances on the same and (ii) Landlord shall be permitted to obtain a date down endorsement to the Elk River Title Policy, and Tenant shall reasonably cooperate with Landlord’s efforts to obtain same, which date down endorsement shall reflect the addition of the Remaining Elk River Property as a portion of the legal description insured by the Elk River Title Policy, such reasonable costs and expenses thereof to be paid for by Tenant.”

(f) Schedule 2 (List of Original Movable Building Equipment) attached to the Original Lease is deleted in its entirety and replaced with Schedule 2 attached hereto and made a part hereof;

(g) Schedule 7.02 (List of Required Repairs) attached to the Original Lease is deleted in its entirety and replace with Schedule 7.02 attached hereto and made a part hereof;

4

(i) Exhibit A-1 (Location/Address of Demised Properties/Adjustment Amounts) attached to the Original Lease is deleted in its entirety and replaced with Exhibit A-1 attached hereto and made a part hereof.

4. Entire Agreement. The entire agreement of the parties with respect to the subject matter hereof is set forth in the Original Lease as amended by this Amendment.

5. Counterparts. This Amendment may be executed in counterparts, each of which shall be deemed an original, and all of which, when taken together, shall be deemed and shall constitute a single, integrated original document.

6. Headings. The section headings of this Amendment are for convenience only and are not intended, and shall not be construed to alter, limit, or enlarge in any way the scope or meaning of the language contained in this Amendment. No inference in favor of or against any party should be drawn from the fact that such party drafted or participated in the drafting of this Amendment or that such provisions have been drafted on behalf of such party.

7. Unitary Lease. For the avoidance of doubt, Landlord and Tenant agree that: the Original Lease, as amended by this Amendment, constitutes a single and indivisible lease as to all of the Demised Properties (as modified by this Amendment) collectively, and shall not be subject to severance or division. In furtherance of the foregoing, Landlord and Tenant each (a) waives, to the fullest extent permitted by Law, any claim or defense based upon the characterization of the Lease (as amended by this Amendment), as anything other than a master lease of all the Demised Properties (as amended by this Amendment), and irrevocably waives, to the fullest extent permitted by Law, any claim or defense that asserts that the Lease (as amended by this Amendment) is anything other than a master lease, (b) covenants and agrees that it will not assert that the Lease (as amended by this Amendment) is anything but a unitary, unseverable instrument pertaining to the lease of all, but not less than all, of the Demised Properties (as amended by this Amendment), (c) stipulates and agrees not to challenge the validity, enforceability or characterization of the Lease of the Demised Properties (as amended by this Amendment), as a unitary, unseverable instrument pertaining to the lease of all, but not less than all, of the Demised Properties (as amended by this Amendment), and (iv) shall support the intent of the parties that the Lease (as amended by this Amendment)is a unitary, unseverable instrument pertaining to the lease of all, but not less than all, of the Demised Properties (as amended by this Amendment), if, and to the extent that, any challenge occurs. To the extent that legal, tax or title insurance requirements in consummating the purchase of the Demised Properties by Landlord or leasing the Demised Properties (in each case, as amended by this Amendment), to Tenant, may require, or may have required, individual purchase price allocations (including allocations of values for individual state transfer tax purposes and title insurance coverage amounts) or individual rent allocations (including allocations of rents in certain states for tax purposes), Landlord and Tenant agree that such individual allocations are solely to comply with legal, tax or title insurance requirements, and shall not be used or construed, directly or indirectly, to vary the intent of Landlord and Tenant that the Lease (as amended by this Amendment) constitutes a single and indivisible lease of all the Demised Properties (as amended by this Amendment) collectively and is not an aggregation of separate leases. The foregoing agreements and waivers by Tenant in this Paragraph 7 are made as a material inducement to Landlord to enter into the transaction contemplated by the Lease as modified by this Amendment and that, but for the foregoing agreements and waivers by Tenant, Landlord would not consummate the Original Lease or this Amendment.

8. Lease in Full Force and Effect. Except as expressly set forth in this Amendment, , all of the terms and provisions of the Original Lease are hereby ratified and confirmed, and the Original

5

Lease (as amended hereby) remains in full force and effect. All references in the Original Lease to “this Lease” (or similar phrase) shall be deemed to refer to the Original Lease as modified by this Amendment, and all references in the Original Lease to “Demised Properties” shall be deemed to refer to the Demised Properties as such term is defined in this Amendment.
