SECTION 1. Amendments to MOSA.

(1) Section 3 of the MOSA is hereby amended by adding the following:

“G. Compensation during a Blackhawk Biofuels Loan Default. Notwithstanding

anything herein to the contrary, if Blackhawk Biofuels is in default under that certain Loan Agreement dated May 9, 2008, as amended (the “Loan Agreement”), between Blackhawk Biofuels and Fifth Third Bank, a Michigan banking corporation (“Lender”), Lender shall have the option in Lender’s sole discretion (but not the obligation), effective upon Lender’s delivery of written notice to REG Services, REG Marketing, and Blackhawk Biofuels, to require Blackhawk Biofuels and/or its assignee to cease making all payments otherwise due under this Agreement. If Lender exercises such option, then REG Services and REG Marketing have the right, but not the obligation, to suspend their duties under this Agreement until such time as Lender allows such payments to resume by subsequent written notice to the parties. Notwithstanding the foregoing, REG Services and REG Marketing shall continue to have such rights to terminate this Agreement as otherwise provided herein for non-payment.”

(2) Section 4 of the MOSA is hereby amended by adding the following:

“G. Provide REG Services and REG Marketing with written notice of an Advance under the Revolving Credit Loan (as such terms are defined in the Loan Agreement), at such time as any notice is provided to Lender under the Loan Agreement, with such notice specifying the amount of the proposed Advance and the proposed date of the Advance.”

SECTION 2. Ratification. Except as amended hereby, the MOSA, and each and every provision thereof, is hereby ratified and confirmed by REG and Borrower, and shall remain in full force and effect by and between REG and Borrower. In the event of any conflict between the MOSA and this Amendment, the terms of this Amendment shall apply.

SECTION 4. Counterparts. This Amendment may be executed in counterparts, all of which taken together shall be deemed one original, and shall be effective upon execution thereof by all parties, notwithstanding the fact that all of the parties hereto are not signatories to the original or same counterpart. Any signature of any party which is delivered by facsimile or photocopy shall be deemed to be an original signature and shall be effective upon receipt thereof.
