Recitals

WHEREAS, REG Marketing is a wholly owned subsidiary of REG, Inc.;

WHEREAS, CIE and REG Marketing entered in to a Central Iowa Energy, LLC Toll Processing Agreement dated as of January 6, 2009 (“Agreement”), which has been extended pursuant to the provisions of Exhibit E to the Agreement;

WHEREAS, CIE and REG Marketing desire to supplement and modify the Agreement with this Addendum #3 specifically pertaining to the toll processing of Corn Oil;

WHEREAS, CIE and REG Marketing recognize and acknowledge that the Corn Oil processing technology, know-how and particularized application as defined and discussed below is novel and highly proprietary to REG, Inc., and further intend that all persons employed by, affiliated with or acquiring knowledge of Technology by or through CIE shall be bound by the strictest requirements of trade secret and confidentiality; and

WHEREAS, REG, Inc., with the strictest adherence to the trade secret and confidentiality provisions of this Addendum #3, is willing to license the use of Corn Oil processing technology, know-how and particularized application to CIE under the umbrella of the Central Iowa Energy, LLC Toll Processing Agreement it has with REG Marketing.

NOW, THEREFORE, in consideration of the covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

1. Additional Feedstock Specifications. As used in Addendum #3, “Corn Oil” means any crude corn oil extracted from distillers dried grains in the ethanol process which meet the quality specifications as appended to Addendum #3 as Attachment #1. For purposes of the Agreement, Corn Oil constitutes Additional Feedstock which REG Marketing may deliver to the Facility to be processed by CIE under the terms of the Agreement as modified herein.

2. Yield Requirement for Additional Feedstock. The Parties agree that for purposes of processing the Corn Oil, the Agreement at Section 6 is amended by changing the first sentence to read:

“In consideration of the Toll Fee and handling of co-products agreed upon, CIE agrees to deliver to REG Marketing not less than 1 Gal of Biodiesel for every *** pounds of Corn Oil delivered by REG Marketing to the Facility which equates to a weight yield of ***% (7.35 lbs biodiesel divided by *** lbs of Feedstock).”

3. Economic Adjustment to Agreement. In view of the different characteristics of the Additional Feedstock (Corn Oil) as set forth in Attachment #1 to this Addendum #3 as compared to the other Feedstock listed within the various Addenda of Exhibit B to the Agreement, the Parties agree to adjust the terms of Section 4 of the Agreement to provide for an incremental By-Product Payment structure. Specifically, the payments due to REG Marketing by CIE shall be based upon the following By-Product Payment formula:

(A) For any Order or Nomination, multiply the number of pounds of Additional Feedstock delivered by REG Marketing to CIE for processing, times the average free fatty acid composition of such Additional Feedstock as a percentage in excess of 4% (the composition to be based upon supplier’s Certificate of Analysis, or as otherwise agreed by the Parties).

(B) Divide the result from “A” above by 80%.

(C) Multiply the result from “B” above by the price received for the free fatty acids sold from such Order or Nomination, which yields the required By-Product Payment.

(D) CIE agrees to pay such By-Product Payment to REG Marketing by wired funds to REG Marketing within one (1) business day of delivery of the Biodiesel to REG Marketing with respect to such Order or Nomination.

4. Trade Secret Protection: Of particular import to this Addendum #3 and the tolling process for Corn Oil is the corn oil based technology, know-how, and particularized application of said technology and know-how (more fully defined as “Technology” below), all of which is confidential and proprietary to REG, Inc. REG, Inc. may or may not pursue patent protection of all or a portion of the Technology. For purposes of the Agreement as it relates to Corn Oil tolling, and specific to this Addendum #3, the Parties specifically acknowledge that all Technology has economic value and should be protected from disclosure to the public in general, and prospective competitors in particular.
