<P ALIGN=CENTER><FONT SIZE=2><B>AGREEMENT</B></FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;THIS
AGREEMENT (the &#147;<B>Agreement</B>&#148;) is
made as of June 30, 2010, by and between Central Farmers Cooperative, a South
Dakota cooperative (&#147;<B>CFC</B>&#148;), and
REX NuGen, LLC, a South Dakota limited liability company (&#147;<B>REX</B>&#148;). CFC and REX are each referred to
herein as a &#147;<B>Party</B>&#148; and together
as the &#147;<B>Parties</B>&#148;. </FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
each Party owns, intends to purchase, or has the right to purchase Class A
Units (the &#147;<B>Units</B>&#148;) of NuGen
Energy, LLC, a South Dakota limited liability company (the &#147;<B>Company</B>&#148;); and </FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
the Parties wish to enter into an agreement with respect to certain matters
related to their ownership of the Units. </FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NOW,
THEREFORE, for good a valuable consideration, the receipt of which is hereby
acknowledged, the Parties agree as follows: </FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>Defined
Terms</U>. All terms not otherwise defined herein shall have the meanings
assigned to such terms in the Company&#146;s Third Amended and Restated Limited
Liability Company Agreement, as the same may be amended, supplemented or
restated from time to time (the &#147;<B>Operating
Agreement</B>&#148;). </FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>Voting
of Units in the Election of Managers</U>. Each Party shall, in any election of
managers of the Company, vote all the Units as to which such Party has voting
discretion so as to cause the Company&#146;s Board of Managers to consist of an odd
number of managers, the majority of which are individuals nominated by CFC and
the remainder of which are nominated by REX. By way of example, if the
Company&#146;s Board of Managers consists of nine (9) managers, five (5) would be
individuals nominated by CFC and four (4) would be individuals nominated by
REX. Except as expressly set forth herein, the Parties may vote their Units in
the election of managers of the Company without restriction. REX and CFC agree
to hold an election of managers as soon as practicable after REX becomes a
member of NuGen. </FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>Removal
of Managers</U>. No Party shall vote to remove a manager nominated by the other
Party without the written consent of the applicable nominating Party. </FONT></P>

<P ALIGN=JUSTIFY><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>Agreement
to Vote Shares</U>. The Parties agree that at any meeting of the Members of the
Company, however called, and in any action taken by written consent of Members
of the Company without a meeting, neither Party shall vote the Party&#146;s Units in
favor of any of the following unless both Parties have previously agreed in
writing to vote in favor of such action: </FONT></P>

and will not become party to any other voting trust, agreement for voting
control, or other like agreement involving any of the voting securities of the
Company owned by such Party during the term of this Agreement, the application
of which would conflict with the provisions of this Agreement. </FONT></P>

<U>Termination</U>. This Agreement will terminate on the earlier of (i) the
effective date of REX owning more than 50 percent of the issued and outstanding
Class A Units and/or voting Units of the Company; (ii) any liquidation,
dissolution or winding up, the sale of all or substantially all of the assets
of the Company, or any consolidation or merger of the Company in which the
Company is not the surviving corporation; (iii) mutual written agreement by the
Parties; or (iv) maximum time, including any applicable renewable periods,

Each Party acknowledges that the other Party will suffer irreparable harm if
the first Party fails to comply with this Agreement, and that monetary damages
will be inadequate to compensate the other Party for such failure. Accordingly,
the Parties agree that this Agreement may be enforced by specific performance
or other injunctive relief, in addition to any other remedies available at law
or in equity. </FONT></P>
