The Company shall use reasonable efforts to notify the Consultant as soon as practicable as to when the Company desires the Services.

ADDITIONAL TERMS AND CONDITIONS
OF NONQUALIFIED OPTIONS UNDER THE
US BIOENERGY CORPORATION 2005 STOCK INCENTIVE PLAN

     1. Active Service. The Optionee must, in the case of an employee, be in the employ of the Company, or in the case of a non-employee director or Consultant, be obligated to serve in that capacity on the relevant dates specified in the Award on which the option first becomes exercisable with respect to the Shares.

     4. Method of Exercise of Option. Subject to the terms of the Plan, the option may be exercised in whole or in part by filing a written notice with the Secretary of the Company at its headquarters prior to the Company’s close of business on the last business day that occurs prior to the Expiration Date. Such notice shall specify the number of Shares which the Optionee elects to purchase, and shall be accompanied by payment of the Exercise Price for such Shares indicated by the election in cash, check or bank draft.

     6. Status and Rights as a Shareholder. Neither the Optionee nor the Optionee’s executor, administrator, heirs, or legatees, shall be or have any rights or privileges of a shareholder of the Company in respect of the Shares transferable upon exercise of the Option granted hereunder, unless the transferee has caused the Optionee’s name to be entered as the shareholder of record on the books of the Company, and if Shares are in certificate form, such certificates representing the Shares have been endorsed, transferred and delivered.

     7. Limitations on Shares.

     3. As a further condition to the Award and the issuance of Shares to the Optionee upon exercise of the option, the Optionee agrees to the following:

     7.0 Investment Intent.

     7.1 Prior to the receipt of the certificates pursuant to the exercise of the option granted hereunder, the Optionee shall, if required in the Company’s discretion, demonstrate an intent to hold the Shares acquired by exercise of the option for investment and not with a view to resale or distribution thereof to the public, by delivering to the Company an investment certificate or letter in such form as the Company may require.

     7.2 Compliance with Securities Laws. Shares acquired upon exercise of this Option may not be sold, transferred, pledged or otherwise disposed of unless the Shares are eligible for resale pursuant to an effective registration under

the Securities Act of 1933, of unless the Company has received an opinion of counsel satisfactory to the Company that said registration is not required.

     7.3 Lock-Up. In the event the Company advises the Optionee that it plans an underwritten public offering of its Common Stock in compliance with the Securities Act of 1933, as amended, and the underwriter(s) seek to impose restrictions under which certain shareholders may not sell or contract to sell or grant any option to buy or otherwise dispose of part or all of their stock purchase rights of the underlying Common Stock, the Optionee will not, for a period not to exceed 180 days from the effective date of the Company’s registration statement, sell or contract to sell or grant an option to buy or otherwise dispose of any shares of Stock acquired pursuant to the exercise of any Stock Option granted to Optionee pursuant to the Plan or any of the underlying shares of Stock without the prior written consent of the underwriter(s) or its representative(s).

     7.4 Sales by Affiliates. The Optionee will comply with Rule 145 of the Securities Act of 1933 and any other restrictions imposed under other applicable legal or accounting principles if the Optionee is an “affiliate” (as defined in such applicable legal and accounting principles) at the time of the transaction, and the Optionee will execute any documents necessary to ensure compliance with such rules.

The Company reserves the right to place a legend on any stock certificate issued upon the exercise of a Stock Option pursuant to the Plan to assure compliance with this Section 7.

     8. Tag Along Rights. If the holders of a majority of the voting power of the Company’s capital stock desire to, collectively, sell or otherwise dispose of a majority of the stock having such voting power (a “Sale Transaction”), they may give a notice (the “Sale Notice”) to all shareholders who have acquired Shares by the exercise of any Stock Option granted under the Plan. The holders of such Shares shall then be obligated to take all lawful action requested by the shareholders giving the Sale Notice to sell or transfer their Shares as a part of the Sales Transaction for the same price per Share as is received by the shareholders giving the Sales Notice. The actions requested may include, without limitation, the deposit of certificates and duly executed stock powers with an escrow agent designated by the shareholders giving the Sales Notice. The provisions of this Section 8 will terminate upon completion by the Company of an initial public offering of its stock.

     9. Right of Repurchase. In the event of the termination of the Optionee’s employment for any reason, the Company may, upon written notice at any time thereafter, repurchase any Shares acquired by the Optionee pursuant to the exercise of any stock option and the Optionee must sell any such shares to the Company, with the per Share price being the Fair Market Value of the Shares as of the date of the termination of the Optionee’s employment, or, in the case of a termination for Cause, an amount equal to the lesser of Fair Market Value or the Exercise Price for the Shares, Such payment shall be made in the form of cash or promissory note payable in no more than five annual installments and bearing a reasonable rate of interest. The provisions of this Section 9 will terminate upon completion by the Company of an initial public offering of its stock.
