Subject to Section 7.5 hereof, Parent shall, through its Board of Directors, unanimously recommend to its shareholders adoption of this Agreement (the “Parent Board Recommendation”), which Parent Board Recommendation shall explain that the shareholders may not approve a plan of distribution of the Shares or dissolution at the same time the members approve the transaction contemplated hereby consistent with Rule 145(a)(3) of the Securities Act.

Notwithstanding the foregoing, the Board of Directors of Parent may withdraw or modify the Parent Board Recommendation if they determine such withdrawal or modification is necessary in the exercise of their fiduciary duties, or approve, recommend, or publicly propose to approve or recommend, a Acquisition Proposal, if such Board determines in good faith that such Acquisition Proposal is a Superior Proposal; provided, however, that no Parent Adverse Recommendation Change may be made in response to a Superior Proposal until after the fifth (5th) Business Day following REG and Buyer’s receipt of written notice (unless at the time such notice is otherwise required to be given there are less than five (5) Business Days prior to the Parent Shareholders Meeting, in which case Parent shall provide as much notice as is reasonably practicable) from Parent (a “Parent Adverse Recommendation Notice”) advising REG and Buyer that the Board of Directors of Parent

intends to make such Parent Adverse Recommendation Change and specifying the terms and conditions of such Superior Proposal (it being understood and agreed that any adverse amendment to the financial terms or other material terms of such Superior Proposal shall require a new Parent Adverse Recommendation Notice and a new five (5) Business Day period (unless at the time such notice is otherwise required to be given there are less than five (5) Business Days prior to the Parent Shareholders Meeting, in which case Parent shall provide as much notice as is reasonably practicable)). In determining whether to make a Parent Adverse Recommendation Change in response to a Superior Proposal, the Board of Directors of Parent shall take into account any changes to the terms of this Agreement proposed by REG and Buyer in writing (in response to a Parent Adverse Recommendation Notice or otherwise) in determining whether such third party Acquisition Proposal still constitutes a Superior Proposal.

(b) Seller shall, as soon as practicable following the date of this Agreement subject to compliance with the requirements of Seller’s Organizational Documents and applicable Law, establish a record date for, duly call, give notice of, convene and hold a meeting of its members for a date in no event later than June 30, 2011 (the “Seller Members Meeting”) for the purpose of obtaining the Seller Member Approval.

The member information statement shall include a copy of the Seller Board Recommendation. Without limiting the generality of the foregoing, Seller’s obligations pursuant to the first sentence of this Section 7.4(b) shall not be affected by (i) the commencement, public proposal, public disclosure or communication to Seller of any Acquisition Proposal or (ii) the withdrawal or modification by the Board of Governors of Seller or any committee thereof of the Seller Board Recommendation or such Board of Governors or such committee’s approval of this Agreement. Except as expressly permitted by this Section 7.4(b), neither the Board of Governors of Seller nor any committee thereof shall (i)(A) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to REG or Buyer, the Seller Board Recommendation or the approval or declaration of advisability by such Board of Governors of this Agreement and the transactions contemplated hereby or (B) approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal (any action described in this clause (i) being referred to as a “Seller Adverse Recommendation Change”), or (ii) approve or recommend, or propose publicly to approve or recommend, or cause or authorize Seller to enter into, any letter of intent, agreement in principle, memorandum of understanding, merger, acquisition, purchase or joint venture agreement or other agreement related to any Acquisition Proposal (other than a confidentiality agreement in accordance with Section 7.5. Notwithstanding the foregoing, the Board of Governors of Seller may withdraw or modify the Seller Board Recommendation if they determine such withdrawal or modification is necessary in the exercise of their fiduciary duties, or recommend a Acquisition Proposal, if such Board determines in good faith that such Acquisition Proposal is a Superior Proposal; provided, however, that no Seller Adverse

Recommendation Change may be made in response to a Superior Proposal until after the fifth (5th) Business Day following REG and Buyer’s receipt of written notice (unless at the time such notice is otherwise required to be given there are less than five (5) Business Days prior to the Seller Members Meeting, in which case Seller shall provide as much notice as is reasonably practicable) from Seller (a “Seller Adverse Recommendation Notice”) advising REG and Buyer that the Board of Governors of Seller intends to make such Seller Adverse Recommendation Change and specifying the terms and conditions of such Superior Proposal (it being understood and agreed that any amendment to the financial terms or other material terms of such Superior Proposal shall require a new Seller Adverse Recommendation Notice and a new five (5) Business Day period (unless at the time such notice is otherwise required to be given there are less than five (5) Business Days prior to the Seller Members Meeting, in which case Seller shall provide as much notice as is reasonably practicable)). In determining whether to make a Seller Adverse Recommendation Change in response to a Superior Proposal, the Board of Governors of Seller shall take into account any changes to the terms of this Agreement proposed by REG and Buyer in writing (in response to a Seller Adverse Recommendation Notice or otherwise) in determining whether such third party Acquisition Proposal still constitutes a Superior Proposal.

7.5 Non-Solicitation. From the date of this Agreement until the earlier of (a) the Closing Date, or (b) the date this Agreement is terminated in accordance with the provisions hereof, neither Parent nor Seller or their respective Representatives will take any action to solicit the making of any Acquisition Proposal or engage in substantive discussions or negotiations with any Person with respect thereto; provided, however, that if after the date hereof the Board of Directors of Parent and/or the Board of Governors of Seller receives an unsolicited, bona fide written Acquisition Proposal made after the date hereof in circumstances not involving a breach of this Agreement, and the applicable Board reasonably determines in good faith that such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal, and with respect to which such Board determines in good faith, after considering applicable provisions of state law and after consulting with and receiving the advice of outside counsel, that the taking of such action is necessary in order for such Board to comply with its fiduciary duties to its members under Minnesota law, then Parent and Seller may, at any time prior to obtaining Parent Shareholder Approval and the Seller Member Approval, respectively, (but in no event after obtaining such approvals) and after providing REG and Buyer not less than two (2) Business Days written notice of its intention to take such actions (A) furnish information with respect to the Selling Parties to the Person making such Acquisition Proposal, but only after such Person enters into a customary confidentiality agreement with the Selling Parties, provided that (1) such confidentiality agreement may not include any provision calling for an exclusive right to negotiate with the Selling Parties and (2) the Selling Parties advise REG and Buyer of all such non-public information delivered to such Person concurrently with its delivery to such Person and concurrently with its delivery to such Person the Selling Parties delivers to REG and Buyer all such information not previously provided to REG and Buyer, and (B) participate in discussions and negotiations with such Person regarding such Acquisition Proposal. Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by the Representatives of the Selling Parties shall be deemed to be a breach of this Section 7.5 by the Selling Parties.

For purposes of this Agreement: “Acquisition Proposal” means any oral or written offer from a third party for, or any written indication of interest by a third party in, any purchase or issuance of any membership interests in Seller or the purchase of all or any material part of the Purchased Assets or Real Property of Seller (other than the sale or other disposition of such Purchased Assets or Real Property in the ordinary course of business consistent with past practice of Seller) or any merger or consolidation of Seller; and “Superior Proposal” means an Acquisition Proposal, which is otherwise on terms and conditions which the Board of Directors of Parent and/or the Board of Governors of Seller determines in its good faith and reasonable judgment (after consultation with outside counsel and a financial advisor) to be more favorable to their respective shareholders or members than the transactions contemplated by this Agreement, taking into account at the time of determination any changes to the terms of this Agreement that as of that time had been proposed by REG and Buyer in writing and the ability of the Person making such proposal to consummate the transactions contemplated by such proposal (based upon, among other things, the availability of financing and the expectation of obtaining required approvals).

7.6 Publicity. No party to this Agreement or any Affiliate or Representative thereof shall issue any press release or make any public announcement relating to the terms or existence of this Agreement prior to or following the Closing without the prior approval of the other parties hereto (which approval shall not be unreasonably withheld); provided, however, that any party may make any public disclosure it believes in good faith is required by applicable Legal Requirements or any listing agreement concerning publicly-traded securities, in which case the disclosing party shall use commercially reasonable efforts to advise the other parties prior to making the disclosure; and further provided that Seller may communicate to its members and to the members of Parent regarding the terms of this Agreement.

7.7 No Assumption of Liabilities. Neither REG nor Buyer assumes any liabilities of Parent or Seller or with respect to the assets or Business of Seller, and Parent and Seller, jointly and severally, shall defend, indemnify and hold REG and Buyer harmless from all liabilities of Parent and Seller and with respect to the assets or Business of Seller, except with respect to the future obligations of Parent or Seller assumed by Buyer under the Assumed Contracts from and after the Closing as provided in the assignment and assumption agreement to be executed by Seller and Buyer at the Closing.

7.8 Environmental Matters.

(a) Seller shall permit REG and Buyer and their environmental consultant to conduct, at the expense of REG and Buyer, such investigations (including investigations known as “Phase I” Environmental Site Assessments and, only if mutually agreed to by Parent, Seller, REG and Buyer, “Phase II” Environmental Site Assessments) of the environmental conditions of the Real Property and the operations on the Real Property (subject to any limitations contained in valid, previously executed leases) as REG and Buyer, in their reasonable discretion, shall deem necessary or prudent (“Buyer’s Environmental Assessment”). Buyer’s Environmental Assessment shall be conducted, at Buyer’s expense, by a qualified environmental consulting firm, possessing reasonable

levels of insurance, in compliance with applicable Laws and in a manner that minimizes the disruption of the operations of Seller. REG and Buyer shall provide copies of reports and results of all investigations conducted by or on behalf of REG and Buyer to Seller and Parent promptly after receipt thereof. Buyer shall be responsible for the repair of any damage (except as a result of any pre-existing contamination) caused by such investigations and shall restore the affected property or reimburse Seller for such damage and the repair and restoration thereof as reasonably determined by Seller.

(b) Parent and Seller shall promptly file or cooperate with REG and Buyer in filing all materials required by Environmental Laws as a result of or in furtherance of the transactions contemplated hereunder, including, but not limited to any notifications or approvals required under environmental property transfer laws, and all requests required or necessary for the transfer or re-issuance of Environmental Permits required to conduct the Business after the Closing Date. REG and Buyer shall cooperate in all reasonable respects with Parent and Seller with respect to such filings and Environmental permit activities.

7.9 No Liquidation or Distribution; Holding Period. Upon Closing of the transaction and the issuance of the Shares, neither Seller nor Parent nor their respective members and shareholders or boards of directors or governors shall adopt or propose a plan of liquidation or dissolution of Seller or Parent or a plan of distribution of the Shares during the twelve (12) month period following the Closing. Notwithstanding the Shares being held by the Escrow Agent for the time period prescribed in the Escrow Agreement and this Agreement, Seller and, if applicable, Parent, agree to hold the Shares issued at Closing beyond the twelve (12) month period if (a) REG completes an initial public offering or listing on a national exchange of REG Common Stock and (b) in connection with such initial public offering or listing enters into an agreement with underwriters that requires that the REG Common Stock be held for a period of time that extends beyond the twelve (12) month period, in which case Seller, and, if applicable, Parent, shall hold the Shares for the additional required period.

7.10 Employees. REG and Buyer shall have the right, but not the obligation, to negotiate employment, consulting, non-competition and related agreements and arrangements with certain employees of Seller as agreed upon between REG, Buyer and the Selling Parties.

7.11 MOSA Termination and Release. Effective at Closing, REG and Seller hereby terminate the Management and Operational Services Agreement dated March, 2005 by and between Seller and West Central Cooperative, and assigned to REG August 7, 2006 and the Memorandum of Understanding dated April 1, 2008 by and between Seller and REG, including any oral or written extensions or amendments to either of the foregoing (together, the “MOSA”), and each further hereby releases and discharges the other and their respective officers, directors, agents, stockholders, subsidiaries and Affiliates, including, but not limited to REG Services Group, LLC and REG Marketing and Logistics Group, LLC, from any claim, liability, loss, damage and expense arising under or by reason of the MOSA through the Closing Date, whether known or unknown, foreseen or unforeseen, or which may hereafter appear or develop, including, but not limited to, any claim, liability, loss, damage or expense for breach or indemnification.

If the Indemnifying Party does not expressly elect to assume the defense of such Third Party Claim within the time period and otherwise in accordance with the first sentence of this Section 9.4(b), the Indemnified Party shall have the sole right to assume the defense of and to settle such Third Party Claim. The Indemnifying Party shall, at the Indemnifying Party’s expense, cooperate with the Indemnified Party in such defense and make available to the Indemnified Party all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. If the Indemnifying Party assumes the defense of any Third Party Claim, the Indemnifying Party shall not, without the prior written consent of the Indemnified Party, enter into any settlement or compromise or consent to the entry of any judgment with respect to such Third Party Claim if such settlement, compromise or judgment (i) involves a finding or admission of wrongdoing, (ii) does not include an unconditional written release by the claimant or plaintiff of the

Indemnified Party from all liability in respect of such Third Party Claim or (iii) imposes equitable remedies or any obligation on the Indemnified Party other than solely the payment of money damages for which the Indemnified Party will be indemnified hereunder.

(c) The Indemnifying Party shall not be entitled to require that any action be made or brought against any other Person before action is brought or claim is made against it hereunder by the Indemnified Party.

(d) Each Indemnifying Party hereby consents to the nonexclusive jurisdiction of any court in which a Proceeding in respect of a Third Party Claim is brought against any Indemnified Party for purposes of any claim that an Indemnified Party may have under this Agreement with respect to such Proceeding or the matters alleged therein and agrees that process may be served on each Indemnifying Party with respect to such claim anywhere.

9.5 Remedy; Limits on Indemnification. Notwithstanding any provision of this Agreement to the contrary:

(a) The sole remedy of the Buyer Indemnified Parties for breach of the Surviving Reps and Warranties shall be the return to REG of the number of the Shares valued at the then-fair market value of the Shares in satisfaction of any indemnification claim by the Buyer Indemnified Parties; provided, however, the Seller will be entitled to retain that number of Shares valued at One Million Nine Hundred Fourteen Thousand Dollars ($1,914,000) based on the then-fair market value of the Shares (the “Retention Amount”); provided further that the Retention Amount shall not be applicable to Losses incurred by a Buyer Indemnified Party as a result of Parent or Seller’s breach of the representations and warranties set forth in Sections 4.1, 4.12 (except as Section 4.12(c) relates to the design and physical condition of the Purchased Assets), 4.13, 4.17, 5.1, 5.2 and 5.3 of this Agreement.

(b) The Indemnified Party may not make a claim for indemnification under Section 9.2(a) or Section 9.3(a), as the case may be, for breach by the Indemnifying Party of a particular representation or warranty after the expiration of the survival period thereof specified in Section 9.1 with respect to such representation or warranty unless notice of such claim was provided to the Indemnifying Party prior to expiration of the applicable survival period.

(c) Each Indemnifying Party acknowledges and agrees that for purposes hereof, Losses shall be calculated based on the amount of Loss that remains after deducting therefrom any insurance proceeds and any indemnity, contribution or other similar payment actually received by an Indemnified Party from any third party with respect thereto.

(d) THE SOLE AND EXCLUSIVE LIABILITY AND RESPONSIBILITY OF EACH INDEMNIFYING PARTY TO ANY INDEMNIFIED PARTY UNDER THIS

AGREEMENT, AND THE SOLE AND EXCLUSIVE REMEDY OF ANY INDEMNIFIED PARTY AGAINST ANY INDEMNIFYING PARTY UNDER THIS AGREEMENT SHALL BE AS SET FORTH IN THIS ARTICLE IX. TO THE EXTENT THAT ANY INDEMNIFIED PARTY HAS ANY LOSSES FOR WHICH IT MAY ASSERT ANY OTHER RIGHT TO INDEMNIFICATION, CONTRIBUTION OR RECOVERY FROM ANY INDEMNIFYING PARTY (WHETHER UNDER THIS AGREEMENT OR UNDER ANY COMMON LAW THEORY OR ANY LEGAL REQUIREMENT), SUCH INDEMNIFYING PARTY HEREBY WAIVES, RELEASES AND AGREES NOT TO ASSERT SUCH RIGHT, AND SUCH PARTY AGREES TO CAUSE EACH OF ITS RESPECTIVE INDEMNIFIED PARTIES TO WAIVE, RELEASE AND AGREE NOT TO ASSERT SUCH RIGHT, REGARDLESS OF THE THEORY UPON WHICH ANY CLAIM MAY BE BASED, WHETHER CONTRACT, EQUITY, TORT, WARRANTY, STRICT LIABILITY OR ANY OTHER THEORY OF LIABILITY.

(e) NOTWITHSTANDING ANYTHING TO THE CONTRARY ELSEWHERE IN THIS AGREEMENT, NO INDEMNIFYING PARTY SHALL, IN ANY EVENT, BE LIABLE FOR ANY CONSEQUENTIAL, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES; PROVIDED THAT THIRD PARTY CLAIMS THAT INCLUDE ANY OF THE FOREGOING TYPES OF DAMAGES SHALL NOT BE LIMITED BY THIS SECTION 9.5(e) AND SUCH DAMAGES SHALL BE DEEMED “LOSSES” FOR ALL PURPOSES OF THIS ARTICLE IX.

(f) THE FOREGOING INDEMNITIES ARE INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS TERMS AND SCOPE THEREOF NOTWITHSTANDING ANY EXPRESS NEGLIGENCE RULE, DOCTRINE RELATING TO INDEMNIFICATION FOR STRICT LIABILITY OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE NEGLIGENCE (WHETHER SOLE, CONCURRENT, ACTIVE OR PASSIVE) OR OTHER FAULT OR STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES.

9.6 Investigation, Disclosure or Knowledge. Notwithstanding any provision contained herein to the contrary, no Indemnified Party shall be entitled to indemnity or other remedy for any Losses if such Indemnified Party had Knowledge on or before the Closing Date of the facts or matters underlying such Losses.

9.7 Tax Treatment of Indemnity Payments. The parties hereto and each Indemnified Party and Indemnifying Party agree to treat any indemnity payment made pursuant to this Article IX as an adjustment to the Purchase Price for federal, state, local and foreign income tax purposes unless a contrary treatment is required under applicable Law.

ARTICLE X

TERMINATION; EFFECT OF TERMINATION

10.1 Termination. This Agreement may be terminated at any time prior to the Closing:

(a) by the mutual written consent of Parent, Seller, REG and Buyer;

(b) by REG or Buyer by giving written notice to Parent and Seller at any time if either of the Parent Shareholders Meeting or the Seller Member Meeting has not been held by June 30, 2011 (in each case, unless the failure or impossibility results primarily from REG or Buyer breaching any representation, warranty, covenant or agreement contained in this Agreement);

(c) by REG or Buyer by giving written notice to Parent and Seller at any time after July 15, 2011 (the “Outside Date”) if the Closing shall not have occurred on or before the Outside Date by reason of the failure of any condition precedent under Section 8.1 hereof or if any such condition becomes impossible to fulfill (in each case, unless the failure or impossibility results primarily from REG or Buyer breaching any representation, warranty, covenant or agreement contained in this Agreement);

(d) by REG or Buyer by giving written notice to Parent and Seller in the event of any exercise of dissenter’s rights by members of Seller;

(e) by Parent or Seller by giving written notice to REG and Buyer at any time after the Outside Date if the Closing shall not have occurred on or before the Outside Date by reason of the failure of any condition precedent under Section 8.2 hereof or if any such condition becomes impossible to fulfill (in each case, unless the failure or impossibility results primarily from Parent or Seller breaching any representation, warranty, covenant or agreement contained in this Agreement); or

(f) subject to compliance by Parent and/or Seller with Sections 7.4 and 7.5 of this Agreement, by Parent or Seller if either party receives a Superior Proposal unless Buyer’s Acquisition Proposal is the Superior Proposal.

10.2 Effect of Termination. Termination of this Agreement pursuant to Section 10.1 shall terminate all obligations of the parties hereunder, without liability of any party to any other party (except for the liability of any party then in breach), except for the obligations under Section 7.7, Article IX, this Section 10.2 and Sections 12.1, 12.7, 12.9 and 12.10.

ARTICLE XI

RISK OF LOSS

11.1 Pre-Closing Risk of Loss. The risk of loss, damage or destruction to the Purchased Assets from fire or other casualty or cause (each, a “Casualty Event”), shall be borne by Seller at all times up to the Closing. To the extent insurance proceeds are available, it shall be the responsibility of Seller prior to the Closing to use reasonable commercial efforts to repair or cause to be repaired and to restore the affected property to its condition prior to any such loss, damage or destruction subject to Sections 11.3 and 11.4 of this Agreement. For the purposes of this Agreement, “Major Casualty” means the loss, damage or destruction to the Purchased Assets from a Casualty Event such that the Purchased Assets cannot be repaired or restored to their

condition prior to any such loss, damage or destruction within sixty (60) days of the Casualty Event.

11.2 Use of Insurance Proceeds. In the event of loss, damage or destruction due to a Casualty Event, the proceeds of any claim for any loss payable under any insurance policy with respect thereto shall be used to repair, replace or restore any such property to its former condition subject to Sections 11.3 and 11.4 of this Agreement.

11.3 Casualty Event Not a Major Casualty. In the event of loss, damage or destruction from a Casualty Event that does not constitute a Major Casualty and any Purchased Asset suffering loss, damage or destruction is not repaired, replaced, or restored prior to the Closing, REG and Buyer, at their sole option, and as their sole remedy with respect to any of the foregoing, upon written notice to Parent and Seller: (a) may elect to postpone Closing until such time as the Purchased Asset has been repaired, replaced, or restored, or (b) may elect to consummate the Closing and accept the Purchased Asset in its then condition, in which event Seller shall assign to Buyer all proceeds of insurance theretofore, or to be, received, covering the Purchased Asset involved; and if REG and Buyer shall extend the time for Closing pursuant to clause (a) above, and the repairs, replacements, or restorations are not completed within sixty (60) days after the date on which all of the conditions set forth in Article VIII have been satisfied or waived (other than conditions which by their nature are to be satisfied at Closing), REG and Buyer may elect at that time to (x) consummate the Closing and accept the Purchased Asset in its then condition, in which event Seller shall assign to Buyer all proceeds of insurance theretofore, or to be, received, covering the Purchased Asset involved, or (y) terminate this Agreement by giving written notice thereof to Parent and Seller, without any party having any liability or obligation under or in respect of this Agreement except for the liability of any party then in breach.

11.4 Major Casualty. In the event of a Major Casualty, any party may, at its sole option and upon written notice to the other parties hereto within thirty (30) days of the Casualty Event, terminate this Agreement without any party having any liability or obligation under or in respect of this Agreement except for the liability of any party then in breach. If the parties fail to exercise their option to terminate in the event of a Major Casualty and if the conditions to Closing set forth in Article VIII hereof have been satisfied or waived (other than conditions which by their nature are to be satisfied at Closing), the parties shall be obligated to close pursuant to the terms of this Agreement, including, but not limited to, delivery of the Purchased Assets in their damaged condition to Buyer and delivery of the Purchase Price to Seller, and the insurance proceeds for any loss payable under any insurance policy with respect to the Casualty Event shall be assigned to REG.
