 BLACKHAWK BIOFUELS, LLC TOLL PROCESSING AGREEMENT

This Blackhawk Biofuels, LLC Toll Processing Agreement (the “Agreement”) is made and entered into effective February 1, 2010, by and between Blackhawk Biofuels, LLC a limited liability company organized and existing under the laws of the state of Delaware, with offices at 22 South Chicago Avenue, Freeport, Illinois 61032 (“Blackhawk Biofuels”). and REG Marketing & Logistics Group, LLC, an Iowa limited liability company (“REG Marketing”), of 416 S. Bell Avenue, PO Box 888, Ames, Iowa 50010 (each a “Party,” and collectively the “Parties”).

Recitals

A.            Blackhawk Biofuels is in the business of manufacturing and processing biodiesel from feedstock at its biodiesel processing facility located at Danville, IL (the “Facility”).

B.            REG Marketing desires to arrange for the purchase and delivery of animal fats and other feedstocks (as specified by the provisions of Section 7 hereafter, herein “Feedstocks”) to Blackhawk Biofuels for processing into biodiesel meeting the specifications set out in Section 8 hereafter (herein “Biodiesel”) and Crude Glycerin, Fatty Acids and Soapstock (“Co-products”) pursuant to a toll processing arrangement.  Blackhawk Biofuels desires that REG Marketing arrange for the delivery of Feedstocks for processing at the Facility.

The Agreement

In consideration of the mutual benefits and obligations herein provided and other good and valuable consideration, Blackhawk Biofuels and REG Marketing agree as follows:

1.             Offers to Deliver Feedstocks for Processing.  REG Marketing may offer to deliver Feedstocks to Blackhawk Biofuels’s Facility at Danville, IL, during the term of this Agreement.

(a)           Orders within Facility Commitment.  REG Marketing shall order the processing to be determined weekly of Feedstocks at the Facility (“Facility Commitment”). Any such order shall set out the type and quantity of Feedstocks, and the Production Week for which such Feedstocks are intended for processing (“Order”).  If such Order is timely made, then unless otherwise agreed by the Parties REG Marketing shall deliver the Feedstocks to Blackhawk Biofuels in time for production of the Biodiesel, Blackhawk Biofuels shall process the Feedstocks and test and certify the Biodiesel as meeting the agreed upon specifications under the applicable Order during such Production Week, and REG Marketing shall arrange to pick up the resulting Biodiesel during the two weeks immediately following such Production Week.  Blackhawk Biofuels agrees to provide written acknowledgment of all Orders placed by REG Marketing.  For purposes of this Agreement, a “Production Week” shall mean a calendar week beginning at 8:00 a.m. on Monday and ending at 7:59 a.m. on the following Monday, with weeks designated for pick up of Biodiesel measured in similar fashion.

1

As an example, for the Production Week commencing January 19, 2009, REG Marketing would need to have delivered its Order for such Production Week on or before 5:00 p.m. on Monday, January 5, 2009.  If such Order has been timely delivered to Blackhawk Biofuels, REG Marketing would then deliver in the Feedstocks required for such Production Week both before and during the production week.  Blackhawk Biofuels would then have the Production Week of January 19 through January 26, 2009, to complete production, test and certify the Biodiesel meets the agreed upon specifications under the applicable Order.  REG Marketing would then have from January 26 through 7:59 a.m. on February 9, 2009, to pick up the Biodiesel produced for such Production Week.  REG Marketing shall develop a sample “Order/Nomination” form to be used by the Parties, which shall be attached as Exhibit A hereto.

Any Feedstocks purchased by Bunge North America, Inc. (“Bunge”) pursuant to the terms of a Feedstock Purchase and Sale Agreement dated June 30, 2009 (the “Feedstock Agreement”) by and between Blackhawk Biofuels, REG Marketing and Bunge shall be included in determining whether the Facility Commitment has been met.  Any purchase of Feedstocks by Bunge, however, shall be governed exclusively by the terms of the Feedstock Agreement and such purchases shall not be subject to the terms of this Agreement.

(b)           Offers in Excess of the Facility Commitment.  REG Marketing may offer to deliver additional Feedstocks beyond the Facility Commitment, subject to Blackhawk Biofuels’s acceptance.  Any such offer (“Nomination”) shall set out the type and quantity of Feedstocks, the Production Week for which such Feedstocks are intended for production, and advise of the time period during which Blackhawk Biofuels shall be required to communicate Blackhawk Biofuels’s acceptance back to REG Marketing (“Offer Period”).  The parties agree that such Offer Period will not expire prior to 12:00 o’clock noon, local time at the Facility, on the business day following that day during which the Nomination is delivered, and provided further that (unless waived by Blackhawk Biofuels) a Nomination shall not propose a Feedstocks delivery schedule with first delivery date less than seven (7) calendar days after the end of the Offer Period.  If a Nomination is accepted by Blackhawk Biofuels (as set out hereafter), then (unless otherwise agreed by the Parties) REG Marketing agrees to deliver the Feedstocks to Blackhawk Biofuels pursuant to the terms of the Nomination prior to such Production Week to utilize in the production of the Biodiesel, Blackhawk Biofuels shall during such Production Week process the Feedstocks and test and certify the Biodiesel as meeting the agreed upon specifications under the applicable Nomination, and REG Marketing shall arrange to pick up the resulting Biodiesel during the two weeks immediately following such Production Week.  The sample “Order/Nomination” form to be used by the Parties is attached as Exhibit A hereto.

2.             Agreement to Process Orders; Consideration of Nominations.

(a)           Orders within Facility Commitment. Blackhawk Biofuels agrees to process Feedstocks for all Orders received per Production Week, such processing to be within the time frame as set out in Section 1(a) above (unless otherwise agreed by the Parties).  Blackhawk and REG Marketing agree that any shortfall in biodiesel production or shipments due in the previous Agreement dated January 1st 2010 may be made up under this Agreement without penalties.

(b)           Nominations in Excess of Facility Commitment.  In addition, should REG Marketing offer to deliver Feedstocks in excess of such Facility Commitment, Blackhawk Biofuels will consider any such Nomination received, and shall have the right (but not any obligation) to accept Nominations received from REG Marketing by notice given during the Offer Period.  If Blackhawk Biofuels gives timely acceptance of a Nomination (pursuant to the provisions set out in this Agreement, herein an “Acceptance”), then Blackhawk Biofuels agrees to process Feedstocks received pursuant to the terms of the Nomination (and such other applicable provisions as set out herein).

3.             Manner of Extending Order, Nominations, Acceptances.  Notwithstanding any provisions of Section 26(a) to the contrary, the Parties may submit Orders, Nominations and Acceptances by telephone or email, provided that any Order, Nomination or Acceptance submitted by telephone must be followed by timely confirmation by email.

4.             Toll Fees and Payment.  Blackhawk Biofuels shall be paid a toll fee of $ *** for every gallon of Biodiesel at standard temperature and pressure delivered to REG Marketing, produced at the Facility from the Feedstocks delivered by REG Marketing for all volumes shipped up to 2,500,000 gallons in a calendar month. Blackhawk Biofuels shall be paid a toll fee of $ *** for every gallon of Biodiesel at standard temperature and pressure delivered to REG Marketing, produced at the Facility from the Feedstocks delivered by REG Marketing for all volumes shipped in excess of 2,500,000 gallons in a calendar month. Payment shall be made as follows:

(a)           The toll Fee under the terms of such Orders or Nominations by wired funds to Blackhawk Biofuels on every Tuesday for Biodiesel delivered to REG Marketing from the prior Tuesday thru Monday of that week. Delivered to REG Marketing shall mean Biodiesel meeting specifications loaded per shipping instructions FOB Danville, IL.

5.             Co-Products.  REG Marketing shall also be entitled to receive at no additional cost, all glycerin and Fatty Acid produced as a result of the processing of the Feedstocks.

6.             Methanol and Catalyst.  REG Marketing shall be responsible for the purchase and delivery of methanol and catalyst to the Facility. The maximum allowed usage of methanol shall be *** gal of methanol per gallon of biodiesel. The maximum allowed usage of catalyst shall be *** lbs per gallon of biodiesel. Blackhawk Biofuels will reimburse REG Marketing for usage of methanol and catalyst above the maximums. The reimbursement will be paid for overusage at the average price of the chemicals multiplied by the overusage amount based on the biodiesel produced on a monthly basis.  REG Marketing will invoice Blackhawk Biofuels within the first week of the following month.  Payment terms will be 7 days from receipt of invoice from REG

Marketing.  If the actual positive or negative usage variance performance is greater than 10% from the values given above, the parties will use data gathered while producing under steady state conditions and adjust the maximum allowed usages with approval to not be unreasonably withheld, conditioned or delayed by either party.  Any changes will be contained in an addendum to this Agreement.

7.             Maximum Feedstock Usage and Overusage.  In consideration of the Toll Fee and handling of co-products agreed upon, Blackhawk Biofuels agrees the Maximum Feedstock Usage(MFU) per Pound of Delivered Biodiesel shall be as defined in Exhibit B for each Feedstock Type.

For feedstocks where a MFU value is clearly identified and not calculated, the actual overuse, if any, will be calculated as follows:

Overusage based on identified MCU = A — ( B x MFU)

Where  A = Actual pounds of Feedstock delivered from aggregate BOL’s

B = Biodiesel produced from Feedstock in gallons at standard conditions

MCU = defined value for feedstock type

For higher FFA feedstocks or blends of feedstocks that do not have an identified MFU and require the calculation, a daily flow proportioned representative composite sample shall be tested and the resulting %FFA will be used in the calculation. for MFU for the resulting production volume.  For feedstocks where a MFU value is calculated and not clearly identified, the actual overuse, if any, will be calculated as follows:

Overusage for High FFA and Blends based on MCU calculation = C — (B x MFU)

Where C = Actual pounds of Feedstock delivered from aggregate BOL’s

B = Biodiesel produced from Feedstock in gallons at standard conditions

MFU = “Exhibit B calculation *1” using daily flow proportioned

representative composite sample

The reimbursement will be paid for overusage at the average price of the feedstock multiplied by the overusage amount based on the biodiesel produced on a monthly basis.  REG Marketing will invoice Blackhawk Biofuels within the first week of the following month.  Payment terms will be 7 days from receipt of invoice from REG Marketing.  If the actual positive or negative usage variance performance is greater than 2% from the values given or calculated in Exhibit B, the parties will use data gathered while producing under steady state conditions and adjust the

4

defined MFU or formula “*1” with approval to not be unreasonably withheld, conditioned or delayed by either party.  Any changes will be contained in an addendum to this Agreement.

8.             Feedstocks.  The Feedstocks to be delivered to the Facility pursuant to this Agreement shall comply with the specifications set forth on Exhibit B attached hereto or the specific purchase order, whichever is the more restrictive specification.  For Example, if the tallow specification for FFA in Exhibit B was <4 and the purchase order defined FFA as less than <2, then <2 shall be the requirement.  Prior to accepting deliveries of Feedstocks, Blackhawk Biofuels shall have the right at its expense to inspect and test the tendered Feedstocks to determine if it meets the specifications required under this Agreement, and if any such Feedstocks does not meet the required specifications then Blackhawk Biofuels shall have the right to reject such Feedstocks and require REG Marketing, at its cost, to replace the same with Feedstocks that meets the required specifications.  Should REG Marketing propose any other type of Feedstocks other than identified on Exhibit B, the Parties shall agree upon the written specifications and MFU applicable to such additional feedstock, and approve and attach such specifications and MFU as an addendum to Exhibit B with approval to not be unreasonably withheld, conditioned or delayed by either party.

9.             Biodiesel.  The Biodiesel to be produced pursuant to this Agreement shall comply with the specifications set forth on Exhibit C attached hereto.  At REG Marketing’s request, two (2) - one (1) litre samples of the Biodiesel to be delivered to REG Marketing by Blackhawk Biofuels shall be made available for testing at REG Marketing’s cost, prior to REG Marketing picking up such Biodiesel.  Should inspection and testing determine that any Biodiesel does not meet the required specifications (whether determined before or after such Biodiesel has been picked up by REG Marketing, and including after delivery to REG Marketing’s customers), REG Marketing shall have the right to reject such Biodiesel, and require Blackhawk Biofuels, at its cost, to replace the same with Biodiesel that meets the required specifications.

10.           Term.  The term of this Agreement shall be until February 28th, 2010 and commence upon its signature by the Parties.

11.           Title.  Except as otherwise provided herein, title to the Feedstocks delivered by REG Marketing pursuant to this Agreement and title to the contractual amount of corresponding Biodiesel and Co-products produced from such Feedstocks shall at all times be and remain with REG Marketing.  Any Feedstocks delivered by REG Marketing pursuant to the terms and conditions of the Feedstock Agreement, however, shall at all times be and remain with Bunge until such time as title to such Feedstocks passes to REG Marketing pursuant to the terms of the Feedstock Agreement.

12.           Risk of Loss; Insurance.  Risk of loss to the Feedstocks and the Biodiesel and Co-Products produced therefrom shall at all times be borne by REG Marketing, and REG Marketing will maintain such property insurance on the Feedstocks and the Biodiesel produced therefrom as REG Marketing shall determine, in its sole discretion.

18.           Product Segregation.  REG Marketing, on behalf of Blackhawk Biofuels, shall be allowed to add additional Feedstocks owned by REG Marketing as needed to meet the quality and yield requirements hereunder, so long as such additional Feedstocks have cold flow characteristics that are capable of meeting the cold flow specifications set out on the applicable Order or Nomination, and the Biodiesel to be produced shall in any event meet the specifications required hereunder, as modified by the Order or Nomination and Acceptance applicable.  In such event, REG Marketing shall off-set any costs for such additional Feedstocks against the toll fees to be paid by REG Marketing pursuant to Section 4 hereof.  Pursuant to the terms of the Feedstock Agreement, Blackhawk Biofuels shall allow Bunge to store the Feedstocks at the Facility; provided, however, such Feedstocks shall be segregated from any Feedstocks owned by REG Marketing pursuant to the terms of this Agreement.

19.           Failure to Process.  If for any reason other than REG Marketing’s failure to deliver Feedstocks, methanol, and catalyst as required under this Agreement (and other than a matter covered by the force majeure provisions of this Agreement) Blackhawk Biofuels fails to process the Feedstocks in to the certified Biodiesel within the time frame contemplated by this Agreement, Blackhawk Biofuels will pay to REG Marketing the amount determined by first dividing the number of pounds of Feedstocks delivered to Blackhawk Biofuels by the Maximum Feedstock Usage per gallon yield under Section 7 and converting to gallons to determine the gallons of Biodiesel which should have been processed (“Required Gallons”); second, subtracting the actual gallons of Biodiesel received by REG Marketing from the Required Gallons to determine the number of gallons which Blackhawk Biofuels failed to process (“Biodiesel Shortage”); and third,  multiply the Biodiesel Shortage by REG Marketing’s average market price per gallon of Biodiesel delivered by Blackhawk Biofuels to REG Marketing up to such time of computation (or if none delivered another reasonable method of determining the market value of Biodiesel FOB Danville as may be agreed by the Parties, or otherwise determined if the Parties can not so agree).

20.           Facility Shutdowns.  Blackhawk Biofuels agrees to notify REG Marketing of any scheduled shutdowns a minimum of thirty (30) days in advance.  In the event there are any Facility shutdowns due to unscheduled power or mechanical problems which will affect receiving or shipping schedules or are anticipated to continue for twenty-four (24) hours or more Blackhawk Biofuels will notify REG Marketing as soon as possible.

21.           Tax Credits; Blending, Shipping & Loading.  Blackhawk Biofuels will, at the request of REG Marketing, blend the Biodiesel with petroleum diesel (supplied by Blackhawk Biofuels at its cost) to create B99.9 biodiesel at no additional charge to REG Marketing.  Any excise tax or income tax credit or refund, including any blender’s credit or CCC credit or refund (“Tax Credits”) relating to the Biodiesel delivered to REG Marketing will be for the account of REG Marketing, and shall be submitted (as applicable) to the United States Internal Revenue Service (“IRS”) or other appropriate entity by Blackhawk Biofuels, unless otherwise requested by REG Marketing Blackhawk Biofuels will not claim any Tax Credits relating to the Biodiesel delivered to REG Marketing without the written consent of REG Marketing.

In addition, Blackhawk Biofuels shall fulfill the requests regarding additives and load temperature as set out on the “Shipping/Loadout Request” form supplied by REG Marketing and complete the loadout information for each load of Biodiesel shipped, all as set out on the attached as Exhibit D hereto.

22.           RINs and Biodiesel Certificates.  Blackhawk Biofuels and REG Marketing shall cooperate with each other to generate Renewable Identification Numbers (RINs) for the gallons of Biodiesel produced pursuant to this Agreement, with such RINs to be the property of REG Marketing.  Blackhawk Biofuels and REG Marketing shall also cooperate with each other to issue biodiesel certificates for the Biodiesel produced pursuant to this Agreement, which certificates shall be suitable for REG Marketing’s use in collecting the $1.00 per gallon blender’s tax credit.  For purposes of clarity, all gallons for these purposes shall be calculated on a temperature corrected basis (at 60° F).

23.           Force Majeure.  Neither Party hereto shall be liable for any delay arising from circumstances beyond its control including acts of God, riot or civil commotion, industrial dispute, fire, flood, drought, act of government, terrorist acts, war, or sabotage (except failures or delays resulting from a lack of a Party’s funds), provided that the Party seeking to be excused shall make every reasonable effort to minimize the delay resulting therefrom and shall give prompt written notice of the force majeure event to the other Party.  The obligations of the Party giving notice, so far as they are affected by the force majeure event, will be suspended during, but not longer than, the continuance of the force majeure event.  The affected Party must act with commercially reasonable diligence to resume performance and notify the other Party that the force majeure event no longer affects its ability to perform under the Agreement.
