RE:Notice of Rescission

Dear Subscriber:

Enclosed with this letter is a rescission offer being made to the subscribers of units in Southern Iowa BioEnergy LLC ("SIBE”), informing you that SIBE has filed a post-effective amendment to its registration statement with the Securities and Exchange Commission. The post-effective amendment contains material changes to SIBE's prospectus. The material changes to the prospectus are described are summarized in the rescission offer and the attachments thereto.

The board of directors of SIBE has determined that due to the nature of the material changes to our project, you should be offered the right to withdraw from SIBE and receive a refund of your investment, together with statutory interest. If you accept this rescission offer, we will release you from all contractual obligations in connection with your investment in SIBE.

Before deciding whether to confirm or withdraw your investment, please carefully read the enclosed rescission offer in order to fully understand the offer. Should you decide to accept this offer and withdraw your investment, please check the box marked “I accept the rescission offer and withdraw my investment” and return the enclosed Rescission Election form to us at the address listed on the Rescission Election form. Upon receipt of the Rescission Election form and expiration of the rescission offer, we will refund the purchase price to you with applicable statutory interest. We currently have all of the investor deposits in escrow which have been accruing interest. The accrued interest may not be sufficient to pay the statutory interest rates depending on the number of investors who rescind their investment. Depending on the number of investors who rescind their investment, we may have to secure additional debt financing to pay the statutory interest which we may not be able to do.

If you decide to reject this offer and confirm your investment, please check the box marked “I decline the rescission offer and elect to confirm my investment” and return the enclosed Rescission Election form along with the completed Subscription Agreement to the address listed on the Rescission Election form.
