EXHIBIT E

EXECUTION

SUBSCRIPTION AGREEMENT

THIS SUBSCRIPTION AGREEMENT is made effective this 17th day of November, 2005, by and between US BioEnergy Corporation, a South Dakota corporation (the “Company”) and CHS Inc., a Minnesota corporation (“CHS”).

WITNESSETH:

In consideration of the mutual promises contained here, and other good and valuable consideration, the Company and CHS hereby agree as follows:

1. Purchase and Delivery. Subject to the terms and conditions of this Agreement, the Company sells to CHS and CHS purchases from the Company as of the Closing Date (as defined below) 35,000,000 shares of Class A Common Stock, $.01 par value of the Company (the “Class A Stock”) at a purchase price of $1.00 per share for an aggregate purchase price of $35,000,000.

2. Closing.

(a) Closing Date. The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of Lindquist & Vennum, 80 South Eighth Street, Suite 4200, Minneapolis, Minnesota 55402 or at such other place as may be mutually acceptable to the parties. The Closing shall occur as of 12:01 a.m. on the date of this Agreement or such other different time or day as may be mutually acceptable to CHS and the Company (the “Closing Date”).

(b) Closing Procedures. At the Closing, the Company will deliver to CHS a certificate representing the Class A Stock purchased by CHS dated the Closing Date and registered in the name of CHS. At the Closing, CHS shall deliver the aggregate price for the Class A Stock stated in Section 1 by wire transfer on the Closing Date to an account designated by the Company.

3. Certain Representations of CHS. In order to induce the Company to sell the Class A Stock to CHS, CHS hereby represents and warrants to the Company as of the Closing Date as follows:

(a) Securities Representations.

(i) Information About the Company. CHS has received and fully reviewed the Amended and Restated Confidential Private Placement Memorandum dated May 31, 2005, including all appendices or exhibits thereto (the “Memorandum”). CHS acknowledges and understands that the Memorandum speaks only as of May 31, 2005 and does not contain all of the information that the Company would be obligated to include in a registration statement filed with the Securities and Exchange Commission (the “Commission”). CHS has had an opportunity to obtain, and has received, from the Company such additional information regarding the terms and conditions of the sale of securities by this Agreement as it deemed necessary. CHS has had an opportunity to ask such questions of, and receive answers from, the Company regarding the terms and conditions of the sale of securities by this Agreement to the extent deemed necessary by CHS. CHS believes it has sufficient knowledge about the business, management and financial affairs of the Company and the terms and conditions of the purchase of the Class A Stock contemplated hereby. Without limiting the generality of the foregoing, CHS understands that the Company is a recently formed development stage company with virtually no operating history, has incurred a substantial loss since its inception and may continue to lose money and will be required to obtain substantial additional debt financing before it can begin construction on and operation of any of its proposed ethanol plants.

(ii) High Degree of Risk. CHS acknowledges that an investment in the Class A Stock involves a high degree of risk, including, but not limited to, the risk that CHS may receive no return on its investment in the Class A Stock and the risk that CHS may of lose its entire investment in the Company. CHS is able to bear the economic risk of investment in the Class A Stock, including the total loss of such investment.

(iii) No Market for Class A Stock; Restrictions on Transfer. CHS acknowledges that (A) there are substantial restrictions on the transfer of the Class A Stock, both under the Securities Act of 1933, as amended (the “Act”) and applicable state securities laws (the “State Laws”); (B) there is not currently, and it is unlikely that in the future there will exist, a public market for the Class A Stock; and (C) accordingly, for the above and other reasons, CHS may not be able to liquidate an investment in the Class A Stock for an indefinite period. CHS realizes that the Class A Stock has not been registered for sale under the Act or State Laws. CHS acknowledges and agrees that the Class A Stock may be resold only pursuant to registration under the Act and the State Laws, or an opinion of counsel acceptable to the Company that such registration is not required.

(iv) Suitability. CHS believes that an investment in the Class A Stock is suitable for CHS based upon CHS’s investment objectives and financial needs, and CHS has adequate means for providing for its current financial needs and particular contingencies and has no need for liquidity of investment with respect to the Class A Stock. CHS has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of an investment in the Class A Stock and CHS has obtained, to the extent CHS deems necessary, its own professional advice with respect to the risks inherent in an investment in the Class A Stock, and the suitability of an investment in the Class A Stock in light of CHS’s financial condition and investment needs.

(v) Investment Intent. CHS has been advised that the Class A Stock is not being registered under the Act or the State Laws and is being offered and sold pursuant to exemptions from such laws and that the Company’s reliance upon such exemptions is predicated in part on CHS’s representations as contained herein. CHS is purchasing the Class A Stock for its own account for investment and without the intention of reselling or redistributing the same. CHS has made no agreement with any other party regarding the sale, transfer, assignment, pledge or hypothecation of the Class A Stock and CHS’s financial condition is such that it is not likely that it will be necessary to dispose of any of the Class A Stock in the foreseeable future. CHS is aware that, in the view of the Commission, the purchase of the Class A Stock 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 Class A Stock and for which the Class A Stock was pledged as security, would represent an intent inconsistent with the representations set forth above. CHS further represents and agrees that if, contrary to the foregoing stated intentions, CHS should later desire to dispose of or transfer any of the Class A Stock in any it will not do so without first obtaining (A) the opinion of counsel satisfactory to the Company that such proposed disposition or transfer lawfully may be made without the registration of the Class A Stock pursuant to the Act and the State Laws, or (B) such registration (it being expressly understood that the Company shall not have any obligation to register such Class A Stock for such purpose).

(vi) No General Solicitation. CHS has not received any general solicitation or general advertising (including communications published in any newspaper, magazine or other broadcast) in connection with its purchase of the Class A Stock. CHS has not engaged in any public solicitation or advertisement with respect to the Class A Stock. To the extent that CHS received information from Roland “Ron” J. Fagen, Gordon W. Ommen, Steven P. Myers, O. Wayne Mitchell, Brian Thome, Chad D. Hatch, Jill L. Wilts or Jennifer A. Johnson acting as officers of the Company, CHS acknowledges that such individuals are acting strictly in their capacity as officers of the Company, and not as employees or

2

agents of Capitaline Advisors, LLC, Global Ethanol, Inc., Fagen, Inc., US Bio Resource Group, LLC or any other entity.

(vii) Domicile. CHS is duly organized under the laws of, and is in good standing in, the state of Minnesota. CHS has its principal office within the state of Minnesota.

(viii) Qualification as an Accredited Investor. CHS is an “accredited investor” as that term is defined by Rule 501 under the Act. CHS was not organized for the specific purpose of acquiring the Class A Stock.

(b) Brokers or Finders. The Company has not, and will not, incur, directly or indirectly, as a result of any action taken by CHS, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with this Agreement.

(c) Tax Liability. CHS has reviewed with CHS’s own tax advisors the tax consequences of an investment in the Class A Stock and the transactions contemplated by this 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. CHS understands that CHS (and not the Company) shall be responsible for CHS’s own tax liability that may arise as a result of its investment in the Class A Stock or the transactions contemplated by this Agreement.

(d) Dilution. CHS acknowledges that the offering price per share materially exceeds amounts paid by some prior purchasers of the Company’s securities and that CHS will experience substantial dilution in the per share book net tangible book value of the Class A Stock.

(e) Counsel. CHS acknowledges that Lindquist & Vennum P.L.L.P. is legal counsel to the Company, whose interests are in conflict with those of CHS, and that Lindquist & Vennum P.L.L.P., as counsel for the Company, does not represent CHS or CHS’s interests in connection with the purchase of the Class A Stock, and that CHS has had timely opportunity to have CHS’s own legal counsel advise CHS regarding the purchase of the Class A Stock.

(f) Due Authorization. This Agreement has been duly authorized by all necessary action on the part of CHS, has been duly executed by an authorized officer or representative of CHS, and is a legal, valid, and binding obligation of CHS enforceable in accordance with its terms. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby do not and will not violate or conflict with the articles of incorporation or by-laws of CHS or violate any legal requirement or order applicable to CHS.

4. Lock-Up. CHS agrees that, if requested by the Company or the managing underwriter of any initial public offering by the Company of the Class A Stock or other securities of the Company pursuant to a registration statement filed with the Commission under the Act (an “IPO”), CHS shall not sell publicly or otherwise transfer or dispose of any securities of the Company held by CHS for a specified period of time (not to exceed 180 days) following the effective date of such registration statement (the “IPO Date”). CHS shall execute such lock-up agreements as the Company or the managing underwriter may reasonably require in connection with this Section 4.

5. Restrictive Legend. CHS also acknowledges and agrees that the Company shall place a restrictive legend on any certificate representing any of the Class A Stock containing substantially the following language:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND HAVE NOT

3

BEEN REGISTERED UNDER ANY STATE SECURITIES LAWS. THEY MAY NOT BE SOLD, OFFERED FOR SALE, OR TRANSFERRED IN THE ABSENCE OF EITHER AN EFFECTIVE REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND UNDER APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH TRANSACTION IS EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND UNDER APPLICABLE STATE SECURITIES LAWS.

CHS agrees that, to enforce the above legend, the Company may place a stop transfer order with its registrar and transfer agent covering all certificates representing any of the Class A Stock.

6. Non-Solicitation. Notwithstanding Section 8(b), as long as CHS (a) has the right to appoint at least one director to the Board of Directors of the Company (the “Board”) and (b) CHS beneficially owns less than 30% of the outstanding voting securities of the Company, CHS will not, without the prior approval of the Board, directly or indirectly, initiate, propose, make or participate in any solicitation of proxies (other than granting its proxy) to vote, or seek to influence any person with respect to for any candidate for election to the Board; provided that CHS shall not be prohibited from voting any Class A Stock owned by it for any candidate for election to the Board.
