(I)Leases. Create, incur, assume, or permit to exist any obligation as lessee under operating leases which should be capitalized in accordance with GAAP for the rental or hire of any real or personal property, except: (1) leases of soybean oil storage tank space with aggregate annual payments not to exceed $400,000.00; (2) railcar leases (including railcar leases from FCL); provided, however, that no new railcar leases, or renewals thereof, may exceed ten years in duration and must be on terms and conditions acceptable to CoBank; and (3) other leases, excluding those allowed above, which do not in the aggregate require the Company to make scheduled payments to the lessors in any fiscal year of the Company in excess of $400,000.00.

2.Except as set forth in this amendment, the MLA, including all amendments thereto, shall continue in full force and effect as written.
