In consideration of the mutual promises contained herein, and other good and valuable consideration, Subscriber hereby agrees, represents and warrants as follows:

1.                                      Agreement of Subscription.

a.                                       Subscriber hereby subscribes to purchase ** 3,103,449 ** Class A capital units of the Company (the “Units”), which Units quantify membership interests in the Company, at a purchase price of $1.45 per Unit, upon the terms and conditions as set forth in this Subscription Agreement, for a Total Purchase Price for the Units of ** $4,500,001.05 **.  (All capitalized terms used in this Subscription Agreement and not otherwise defined herein shall have the meaning ascribed to such terms in the prospectus of the Company dated September 17, 2004.)

b.                                      Upon the acceptance of this Subscription Agreement, Subscriber agrees to deliver by wire transfer on the same business day of the acceptance the amount of the Total Purchase Price for the Units (100% payment is due upon Subscription).  Subscriber agrees that the Units shall be governed by and that Subscriber is bound by the Company’s Member Control Agreement dated effective September 23, 2004, as amended, (the “Member Control Agreement”).  Subscriber acknowledges that Subscriber is a current member of the Company and therefore has received a copy of the Member Control Agreement.

d.                                      Upon acceptance, this Subscription Agreement is binding on Subscriber, and the obligations of Subscriber hereunder are unconditional.

e.                                       Subscriber acknowledges and agrees that 100% of Subscriber’s purchase price of the Units constitutes “AT-RISK” capital and will not be placed into any type of escrow.  Immediately following acceptance of this Subscription by the Company and tender of the payment for the Units, the Company will use such funds for general working capital and other corporate purposes, as determined by or under the direction of the Board of Governors of the Company at its sole discretion.  Subscriber acknowledges that there is no specified use of the funds from this subscription.

f.                                         Company acknowledges and agrees that, as an inducement to Subscriber to subscribe for the purchase of Units, Company will, within sixty (60) days of receipt of written request from Subscriber, allow ICM, Inc. (“ICM”) at ICM’s sole cost and expense to enter upon Company’s premises for a period of five (5) business days during normal business hours (“Training Period”) and allow ICM to operate the plant alongside Company’s operators in a joint effort to achieve optimal efficiencies with respect to operations and emissions; and to train Company’s operators in a joint effort to achieve optimal operations of the plant under sustainable operating conditions; PROVIDED and ONLY upon the following conditions: (a) Company shall in all cases maintain control

and final authority over all operational decisions during such Training Period; (b) at no time during such Training Period shall the plant be operated under non-sustainable or unsafe operating conditions, meaning without limitation no injections of dry sorbents (other than limestone) directly into the combustor and no short term massive injections of dry sorbents into the baghouse; (c) all such training and joint efforts by ICM shall be at absolutely no cost to Company whatsoever; and (d) all such training and joint efforts shall not disrupt or interfere with normal operations of the plant or other day-to-day business activities of Company.

g.                                      Upon acceptance of this Subscription Agreement and tender of full payment of the entire subscription amount, the Company will issue the Units to Subscriber for the Units purchase hereunder and issue a certificate to Subscriber for the Units purchased hereunder.  Subscriber acknowledges and agrees that Subscriber is bound by the Company’s Articles of Organization attached to the Company’s prospectus dated September 17, 2004 as Appendix A (the “Articles”) and the Member Control Agreement.

2.                                      Representations and Warranties of Subscriber.

In consideration of the Company’s offer to sell the Units, and in order to induce the Company to sell the Units to Subscriber, Subscriber hereby represents and warrants to the Company and its agents as follows:

a.                                       SEC Reporting Obligations; Information About the Company and the Units.  Subscriber acknowledges that the Company is a public reporting company under the Securities Exchange Act of 1934, and that Subscriber has immediate reporting obligations under such Act of its purchase of the Units hereunder, as a result of Subscriber’s ownership of membership interests in the Company and the number of Units purchased.  Subscriber, or its representative(s), has received, read and understands the business, financial and operating information, and the risk factors affecting the Company and its business and the value of the Units being purchased hereunder,  as described in or set forth in the following reports and schedules filed by the Company with the SEC (including all exhibits and financial statement schedules attached thereto or included therewith): (1) FORM 10-K Annual Report filed pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 (the “34’ Act”) for the fiscal year ended October 31, 2009; (2) SCHEDULE 14A Definitive Proxy Statement filed pursuant to Section 14(a) of the 34’ Act for the Annual Meeting of Member held on march 18, 2010; and (3) FORM 10-Q Quarterly reports under Section 13 or 15(d) of the Act for the fiscal quarters ended January 31, 2010 and April 30, 2010.  In addition, Subscriber acknowledges it has received the Company’s unaudited, non-public, financial statements for May 31, 2010 and the 7-month period then ended, by reason of its appointees to the Company’s Board of Governors.  Without limiting the foregoing, Subscriber acknowledges that the Company is seeking a new air permit with the MPCA and the Company will remain out of compliance with one or more covenants in its loan agreement with its senior lenders.  There are no assurances that a new permit will be issued, that the covenant(s) violations can be cured or that the Company will not violate additional loan covenants in the near future, or that the Senior lenders will not declare an event of default and exercise all of their rights and remedies under the loan agreement if the Company cannot cure such defaults or violations.  Subscriber, or its representative, has had an opportunity to obtain, and has received, any additional information and has had an opportunity to ask such questions of, and receive answers from, the Company or an agent or representative of the Company, to the extent deemed necessary by Subscriber in order to form a decision concerning an investment in the Company.  As a result, Subscriber believes it has sufficient knowledge about the business, management and financial affairs of the Company and the ethanol plant and the Company’s planned use of the proceeds of this subscription, and the terms and conditions of the purchase of Units contemplated hereby.

b.                                       High Degree of Risk.  Subscriber realizes that an investment in the Units involves a high degree of risk, including, but not limited to, the risks of receiving no return on the investment and of losing Subscriber’s entire investment in the Company.

c.                                       Ability to Bear the Risk.  Subscriber is able to bear the economic risk of investment in the Units, including the total loss of such investment.

d.                                       No Market for Units; Restrictions on Transfer.  Subscriber realizes that (i) there are substantial restrictions on the transfer of the Units, both under the Securities Act and State Laws, as well as under the Articles

2

and the Member Control Agreement; (ii) there is not currently, and it is unlikely that in the future there will exist, a public market for the Units; and (iii) accordingly, for the above and other reasons, Subscriber may not be able to liquidate an investment in the Units for an indefinite period.  Subscriber realizes that the Units have not been registered for sale under the Securities Act of 1933, as amended (the “Securities Act”) or applicable state securities laws (the “State Laws”).  Subscriber acknowledges and agrees that the Units may be sold only pursuant to registration under the Securities Act and State Laws, or an opinion of counsel acceptable to the Company that such registration is not required, and in accordance with the Articles and the Member Control Agreement.

e.                                       Suitability.  Subscriber believes that the investment in the Units is suitable for the undersigned based upon Subscriber’s investment objectives and financial needs, and Subscriber has adequate means for providing for his, her or its current financial needs and personal contingencies and has no need for liquidity of investment with respect to the Units.  Subscriber has such knowledge and experience in financial and business matters that he, she or it is capable of evaluating the merits and risks of an investment in the Units or Subscriber has obtained, to the extent Subscriber deems necessary, his, her or its own professional advice with respect to the risks inherent in the investment in the Units, and the suitability of the investment in the Units in light of Subscriber’s financial condition and investment needs.

f.                                         Investment Intent.  Subscriber has been advised that the Units are not being registered under the Securities Act or the relevant State Laws but are being offered and sold pursuant to exemptions from such laws and that the Company’s reliance upon such exemptions is predicated in part on Subscriber’s representations to it as contained herein.  Subscriber represents and warrants that the Units are being purchased for Subscriber’s own account and for Subscriber’s investment and without the intention of reselling or redistributing the same, that Subscriber has made no agreement with others regarding any of the Units and that Subscriber’s financial condition is such that it is not likely that it will be necessary to dispose of any of the Units in the foreseeable future.  Subscriber is aware that, in the view of the Securities and Exchange Commission, a purchase of the Units with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market values, or any change in the condition of the Company, or in connection with a contemplated liquidation or settlement of any loan obtained for the acquisition of the Units and for which the Units were pledged as security, would represent an intent inconsistent with the representations set forth above.  Subscriber further represents and agrees that if, contrary to the foregoing stated intentions, Subscriber should later desire to dispose of or transfer any of the Units in any manner, he, she or it shall not do so without first obtaining the consent of the Company as required by the Company’s Articles and the Member Control Agreement and (i) the opinion of counsel satisfactory to the Company that such proposed disposition or transfer lawfully may be made without the registration of the Units pursuant to the Securities Act and applicable State Laws, or (ii) such registration (it being expressly understood that the Company shall not have any obligation to register such Units for such purpose).

g.                                      Brokers or Finders.  Subscriber has not taken any action that will cause the Company to incur, directly or indirectly, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with this Subscription Agreement.

h.                                      Tax Liability.  Subscriber has reviewed with Subscriber’s own tax advisors the tax consequences of this investment and the transactions contemplated by this Subscription Agreement, and has and will rely solely on such advisors and not on any statements or representations of the Company or any of its agents.  Subscriber understands that Subscriber (and not the Company) shall be responsible for Subscriber’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Subscription Agreement.

i.                                         Residency.  Subscriber has its principal place of business in the following State:

Minnesota.
