Provista Second Amended and Restated Guaranty

We entered into a Second Amended and Restated Guaranty effective as of November 2, 2007. The terms of the guaranty provide that we will guaranty up to the lesser of 50% or $10 million of Provista Renewable Fuels Marketing, LLC’s debt outstanding pursuant to the Amended and Restated Loan and Security Agreement dated as of August 31, 2006, between Provista Renewable Fuels Marketing, LLC and LaSalle Bank National Association, as subsequently amended. Prior to execution of the guaranty by us, CHS, Inc. had guaranteed up to $20 million of Provista’s indebtedness under the loan agreement. Following the execution of the guaranty, CHS, Inc.’s guaranty was reduced to $10 million by the execution of a Guaranty substantially similar to that executed by us.

See Exhibit 99.1 for information regarding certain relationships between US BioEnergy, CHS, Inc. and Provista.

The descriptions of the provisions of the guaranty and loan agreement set forth above in Item 1.01 of this Current Report on Form 8-K are qualified in their entirety by reference to the full and complete terms of such agreements, copies of which are attached to this report as exhibits hereto.

First Amendment to the Amended and Restated Services Agreement with Capitaline Advisors

On November 1, 2007, we amended our Amended and Restated Services Agreement dated May 1, 2007, with Capitaline Advisors, LLC. Pursuant to the terms of the agreement, we will now pay Capitaline $3,250 per month for administrative services and $4,250 a month for office services, and Capitaline will pay us $2,750 per month for certain defined information technology-related services.

Capitaline Advisors, LLC is 100% owned and controlled by Gordon W. Ommen, US BioEnergy’s chief executive office, president and chairman of the board. Mr. Ommen beneficially owns approximately 8.06% of US BioEnergy’s outstanding common stock either individually or through his ownership and control of BirdDog Capital, LLC, Mr. Ommen’s private investment company, and Capitaline Advisors, LLC, which is the manager of Capitaline General Partner, LLC, the general partner of a number of Capitaline investment funds. Steve Myers, one of US BioEnergy’s former directors, is the president of Capitaline Advisors. See Exhibit 99.2 for additional information regarding certain relationships between US BioEnergy Corporation and Capitaline Advisors, LLC and its affiliates.

Item 1.02 Termination of a Material Definitive Agreement

Director Compensation

Following our Compensation Committee’s review of the existing terms of compensation for non-employee directors, on October 2, 2007, the Compensation Committee approved modifications to the terms of compensation to be paid to our non-employee directors. Effective January 1, 2008, the compensation terms for non-employee members of our board of directors will be as described below.

Annual Cash Retainer

The non-employee members of our board of directors will receive annual cash retainers of $40,000 in connection with their services as directors. The chairman of our audit committee receives an additional annual retainer of $9,000, with audit committee members each receiving additional annual retainers of $6,000. The chairman of each of our compensation, finance and planning, and nominating and corporate governance committees currently receives an additional annual retainer of $6,000, with the members of those committees each receiving additional annual retainers of $4,000.

The annual cash board and committee retainers are paid quarterly in arrears, with prorated payments paid to those who commence serving as non-employee directors mid-quarter.

Annual Restricted Stock Grant

On the date of each of our annual meetings, each non-employee director who continues to serve on such date will receive restricted shares of our common stock with a value of $65,000, with prorated awards to be paid to non-employee directors who commenced serving as non-employee directors after the previous annual shareholders meeting. The restricted shares will vest on the first anniversary of the grant date. Non-employee directors may elect to receive all or a portion of their annual cash retainer in shares of our common stock under the 2006 Stock Incentive Plan.

Meeting Fees; Reimbursement for Expenses

Non-employee directors do not receive meeting fees for attending (in person or by teleconference) board or committee meetings. Our non-employee directors are reimbursed for reasonable out-of-pocket expenses incurred in connection with attending board and committee meetings.

Change in Control Agreements

In connection with our Compensation Committee’s review of the Company’s compensation practices for executive officers, the Compensation Committee of our board of directors recognized that, as is the case with many publicly held corporations, the possibility of a change in control exists and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders. As a consequence, the Compensation Committee has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the Company’s management to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a change in control.

On September 28, 2007, the Company entered into change in control agreements with each of Gordon Ommen, Chief Executive Officer and President, Richard Atkinson, Senior Vice President and

Chief Financial Officer, Gregory Schlicht, Vice President, General Counsel and Corporate Secretary, Chad Hatch, Vice President of Corporate Development, and Kim Regenhard, Vice President of Human Resources and Communications, in a form approved by the Compensation Committee of the board of directors of the Company. The change in control agreements provide severance payments and benefits to the applicable executive if the executive’s employment with the Company is terminated by the Company other than for cause or if the executive resigns for good reason, in either case within two years following a change in control of the Company. The change in control agreements are intended encourage the continued attention of the executive to his or her duties with the Company without distraction which may be entailed by the possibility of a change in control of the Company.

Pursuant to the change in control agreements, each of the foregoing officers would be entitled to the following severance benefits in the event his or her employment was terminated under the qualifying circumstances described above within two years following a change in control: (i) a severance payment equal to two times (three times for Mr. Ommen) of the sum of the executive’s annual base salary and the higher of the executive’s target annual bonus for the year of termination or the bonus paid to the executive in the prior year; and (ii) continued medical, dental and vision insurance benefits for 24 months (36 months in the case of Mr. Ommen) following termination. Under the change in control agreements, all then unvested equity awards will also immediately vest upon the occurrence of a change in control of the Company. If an officer is subject to a “golden parachute” excise tax under Section 4999 of the Internal Revenue Code, payments under the change in control agreement will be reduced to the extent necessary so that no excise tax is imposed upon the executive.

A form of Change in Control Agreement as entered into between the Company and each of the aforementioned executives is incorporated by reference herein and is attached hereto as Exhibit 10.1.
