(ii)                                  Any fractional share of Parent Common Stock or of Parent Preferred Stock issuable to a holder of Company Units as a consequence of the determination of the Common Stock Per Unit Closing Merger Consideration or Preferred Stock Per Unit Closing Merger Consideration for such holder in accordance with Section 3.1(a)(i) shall be rounded up to the next full share of Parent Common Stock or Parent Preferred Stock, as the case may be, and the total number of shares of Parent Common Stock and Parent Preferred Stock issued as a consequence of such rounding up shall be considered part of the Per Unit Total Merger Consideration for purposes of this Section 3.1(a) and the transactions contemplated by this Agreement.

(iii)                               At the Effective Time, all of the Company Units outstanding immediately prior to the Effective Time, except for Company Units held by REG or any Affiliate of REG, shall cease to be outstanding, shall be cancelled and shall cease to exist, and each certificate (a “Company Certificate”) formerly representing any of the Company Units

16

(other than Excluded Units) shall thereafter represent only the right to receive the Per Unit Total Merger Consideration and any dividends or other distribution pursuant to Section 3.2(c).

(iv)                              The Common Stock Per Unit Closing Merger Consideration and the Preferred Stock Per Unit Closing Merger Consideration shall be collectively referred to herein as the “Per Unit Total Merger Consideration.”  The Per Unit Total Merger Consideration multiplied by the number of Company Units, plus any shares of Parent Common Stock and Parent Preferred Stock issuable in connection with fractional shares, shall be referred to herein as the “Merger Consideration.”  The units of membership interests of the Company immediately prior to the Effective Time shall be referred to herein individually as a “Company Unit” and collectively as the “Company Units.”  The shares of Parent Common Stock and Parent Preferred Stock shall be referred to herein individually as a “Parent Share” and collectively as the “Parent Shares.”

(b)                                 Cancellation of Excluded Units.  Except for Company Units held by REG or any Affiliate of REG, each Excluded Unit shall, by virtue of the Merger and without any action on the part of the holder of the Excluded Unit, cease to be outstanding, be cancelled without payment of any consideration therefor and shall cease to exist.  All Company Units held by REG or any Affiliate of REG shall remain outstanding.

(c)                                  MergerLLC Units.  At the Effective Time, the units of membership interests of MergerLLC shall be converted into units of membership interests of the Surviving Company and shall thereafter constitute the only outstanding units of membership interests of the Surviving Company.

Section 3.2                                      Exchange of Certificates.

(a)                                  Surrender of Company Certificates.  At the Effective Time, any member of the Company who surrenders Company Certificates (or affidavits of loss in lieu thereof as provided in Section 3.2(e)) representing Company Units to the Exchange Agent for cancellation together with any other related documentation reasonably requested by the Exchange Agent to be provided in connection therewith, shall have the right to payment in respect of such Company Certificates in accordance with paragraph (b) below.  After the Effective Time, each outstanding Company Certificate will be deemed for all corporate purposes to evidence only the right to receive the Per Unit Total Merger Consideration in accordance with the provisions of this Article III.

(b)                                 Exchange Procedures.

(i)                                     As of the Effective Time, Parent shall, with the Company’s prior approval, which shall not be unreasonably withheld, appoint an agent to act as an exchange agent (the “Exchange Agent”) for the purpose of issuing the Merger Consideration and any dividends or other distributions with respect to the Parent Shares to be issued or paid pursuant to Sections 3.1 and 3.2(c) (such certificates representing Parent Shares together with cash in the amount of any dividends or other distributions payable with respect

17

thereto being hereafter referred to as the “Exchange Fund”).  At or prior to the Effective Time, Parent shall make available or cause to be made available the stock certificates representing the Parent Shares referred to in Section 3.1 to the Exchange Agent.  Promptly following the Effective Time, Parent shall cause to be made available to the Surviving Company all cash, if any, required for the Exchange Fund.

(ii)                                  At and following the Effective Time, upon surrender to the Exchange Agent of the Company Certificates (or affidavits of loss in lieu thereof as provided in Section 3.2(e)) by members of the Company, the Exchange Agent shall deliver or cause to be delivered upon such surrender to each such member the number of Parent Shares equal to (x) the number of Company Units represented by such Company Certificate (or affidavit of loss in lieu of the Company Certificate as provided in Section 3.2(e)) multiplied by (y) the appropriate Per Unit Closing Merger Consideration, to an address designated by such member in writing.  Any Company Certificate so surrendered shall forthwith be cancelled.  No interest will be paid or accrued on any amount payable upon due surrender of the Company Certificates.

(c)                                  Distributions with Respect to Unexchanged Company Units. Except REG and any Affiliate of REG, no Person holding a Company Certificate will be entitled after the Effective Time to receive any dividend or distribution that may be declared or paid in respect of Parent Shares receivable by such Person upon conversion of Company Units represented by such Company Certificate in the Merger until such Company Certificate is surrendered in exchange for the Merger Consideration as provided herein, at which time any dividends with the record date after the Effective Time with respect to Parent Shares shall, subject to applicable law, be paid without interest to such Person as though he had been a record holder of such Parent Shares at the time of such record date.

(d)                                 Transfers.  Except for Company Units held by REG or any Affiliate of REG, from and after the Effective Time, there shall be no transfers on the unit transfer books of the Company of the Company Units that were outstanding immediately prior to the Effective Time.  If, after the Effective Time, any Company Certificate is presented to the Surviving Company or Parent for transfer, it shall be cancelled and exchanged for the Parent Shares to which the holder of the Company Certificate is entitled pursuant to this Article III.  In the event of a transfer of ownership of Company Units that is not registered in the transfer records of the Company, a certificate for any Parent Shares to be exchanged upon due surrender of the Company Certificate may be issued to such transferee if the Company Certificate formerly representing such Shares is presented to the Surviving Company or Parent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable unit transfer taxes have been paid or are not applicable.

(e)                                  Lost, Stolen or Destroyed Certificates.  In the event any Company Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in customary amount and upon such terms as may be required by Parent as indemnity against any claim that may be made against it or the

18

Surviving Company with respect to such Company Certificate, Parent will deliver or cause to be delivered the number of Parent Shares (after giving effect to any required tax withholdings) equal to the number of Company Units represented by such lost, stolen or destroyed Company Certificate multiplied by the Per Unit Closing Merger Consideration.

Section 3.3                                      Treatment of Company Options and Warrants.

(a)                                  Company Options.  Except as set forth in Section 3.3(b) below, all Company Options, including without limitation all Company Options held by REG or any Affiliate of REG, shall, by virtue of the Merger and without any action on the part of the holder of the Company Options, cease to be outstanding, be cancelled without payment of any consideration therefor and shall cease to exist; provided, however, that cancellation of Company Options hereunder shall not cancel any underlying debt owed by Company to REG or any Affiliate of REG except as to the convertibility thereof.  All such debt owed by Company to REG or any Affiliate of REG shall remain outstanding pursuant to the terms thereof.

(b)                                 Company Warrants.  All warrants of the Company constituting Company Options set forth on Company Disclosure Schedule 3.3(b) (excluding warrants and any other rights to acquire Company Units held by REG or any Affiliate of REG) (the “Company Warrants”) shall be assumed by Parent and will entitle the holder, upon exercise pursuant to the terms and conditions of the Company Warrant, to receive that amount of Parent Common Stock to which a holder of the Company Units purchasable upon exercise of the Company Warrant at the time of the Merger would have been entitled to receive upon the Merger and waiving the right to receive Parent Preferred Stock to which a holder of the Company Units purchasable upon exercise of the Company Warrant at the time of the Merger would have been entitled to receive upon the Merger, with the exercise price for such Parent Shares adjusted accordingly under the Company Warrant.  The exercise date for each of the Company Warrants upon assumption by Parent shall be extended to a date which is determined by adding to the expiration date of each Company Warrant that number of days from and including December 19, 2009 through the date immediately preceding the one year anniversary of the Closing Date.

Section 3.4                                      Adjustments to Prevent Dilution. In the event that the Company changes the number of Company Units or securities convertible or exchangeable into or exercisable for Company Units, or Parent changes the number of Parent Shares or securities convertible or exchangeable or into or exercisable for Parent Shares, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split, share combination, stock dividend (other than a regular interim or final stock dividend) or distribution, recapitalization, merger, subdivision, issue or tender or exchange offer, or other similar transaction, the Per Unit Total Merger Consideration shall be equitably adjusted.

understanding, merger, acquisition, purchase or joint venture agreement or other agreement related to any Takeover Proposal (other than a confidentiality agreement in accordance with Section 6.6(a)).  Notwithstanding the foregoing, the Board of Managers of the Company may withdraw or modify the Company Board Recommendation if they determine such withdrawal or modification is necessary in the exercise of their fiduciary duties, or recommend a Takeover Proposal, if such Board determines in good faith that such Takeover Proposal is a Superior Proposal; provided, however, that no Company Adverse Recommendation Change may be made in response to a Superior Proposal until after the fifth (5th) Business Day following Parent’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 Company Unitholders Meeting, in which case the Company shall provide as much notice as is reasonably practicable) from the Company (a “Company Adverse Recommendation Notice”) advising Parent that the Board of Managers of the Company intends to make such Company Adverse Recommendation Change and specifying the terms and conditions of such Superior Proposal (it being understood and agreed that any material amendment to the financial terms or other material terms of such Superior Proposal shall require a new Company 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 Company Unitholders Meeting, in which case the Company shall provide as much notice as is reasonably practicable)).  In determining whether to make a Company Adverse Recommendation Change in response to a Superior Proposal, the Board of Managers of the Company shall take into account (i) any changes to the terms of this Agreement proposed by Parent in writing (in response to a Company Adverse Recommendation Notice or otherwise) and (ii) the amount of the Termination Fee payable to Parent hereunder in determining whether such third party Takeover Proposal still constitutes a Superior Proposal.

(d)                                 For purposes of this Agreement:

“Takeover Proposal” means any inquiry, proposal or offer from any Person or “group” (as defined in Section 13(d) of the Exchange Act), other than Parent and its Subsidiaries or REG and its Subsidiaries, relating to any (i) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of assets of the Company equal to 15% or more of the Company’s assets or to which fifteen percent (15%) or more of the Company’s revenues or earnings are attributable, (ii) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of fifteen percent (15%) or more of any class of equity securities of the Company, (iii) tender offer or exchange offer that if consummated would result in any Person or “group” (as defined in Section 13(d) of the Exchange Act) beneficially owning fifteen percent (15%) or more of any class of equity securities of the Company or (iv) merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company; in each case, other than the transactions contemplated by this Agreement.

“Superior Proposal” means a bona fide written offer, obtained after the date hereof and not in breach of this Agreement, to acquire, directly or indirectly, for consideration consisting of cash and/or securities, all of the equity securities of the Company or all or substantially all of the assets of the Company, or to merge or consolidate with the Company, made by a third party, which is otherwise on terms and conditions which the Board of Managers of the Company

56

determines in its good faith and reasonable judgment (after consultation with outside counsel and a financial advisor) to be more favorable to the Company’s unitholders 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 Parent 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).

Section 6.7                                      Preservation of Records.  Parent agrees that it shall preserve and keep the records held by it or its Affiliates relating to the Business for a period equal to the same period as it determines to be prudent for its own records of a similar type, but in no event less than the applicable statutes of limitation for federal and state income tax purposes with respect to tax records used or useful for tax and accounting purposes, and shall make such records and personnel available to the Company or its members as may be reasonably required by the Company or its members in connection with, among other things, preparation and filing of tax returns and related matters, any insurance claims by, legal proceedings against or governmental investigations of the Company or any of its Affiliates or members or in order to enable the Company to comply with its obligations under this Agreement and each other agreement, document or instrument contemplated hereby or thereby.

Section 6.8                                      Publicity.  None of the Company, REG, Parent or MergerLLC shall issue any press release or public announcement concerning this Agreement or the transactions contemplated hereby without obtaining the prior written approval of the other parties hereto, which approval will not be unreasonably withheld or delayed, unless, in the sole judgment of REG, Parent, MergerLLC or the Company, as applicable, disclosure is otherwise required by applicable Law or by the applicable rules of any stock exchange on which Parent or the Company lists securities; provided that, to the extent required by applicable Law, the party intending to make such release shall use its commercially reasonable efforts consistent with such applicable Law to consult with the other party with respect to the timing and content thereof.

Section 6.9                                      Environmental Matters.

(a)                                  The Company shall permit, at Parent’s expense, Parent and Parent’s environmental consultant to conduct such investigations (including investigations known as “Phase I” Environmental Site Assessments and, only if mutually agreed to by the Company and Parent, “Phase II” Environmental Site Assessments) of the environmental conditions of any real property owned, operated or leased by or for the Company and the operations thereat (subject to any limitations contained in valid, previously executed leases) as Parent, in its reasonable discretion, shall deem necessary or prudent (“Parent’s Environmental Assessment”).  Parent’s Environmental Assessment shall be conducted, at Parent’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 the Company.  Parent shall provide to the Company copies of reports and results of all investigations conducted by or on behalf of Parent promptly after receipt thereof.  Parent shall be responsible for the repair of any damage (except as a result of any pre-existing contamination caused by the Company) caused by

57

such investigations and shall restore the affected property or reimburse the Company for such damage and the repair and restoration thereof as reasonably determined by the Company.  Parent shall indemnify the Company for any loss (except as a result of any pre-existing contamination caused by the Company), including claims of lessors and other parties, resulting from such investigations.

(b)                                 The Company shall promptly file or cooperate with Parent 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.  Parent shall cooperate in all reasonable respects with the Company with respect to such filings and Environmental permit activities.

Section 6.10                                Cooperation with Indebtedness Renegotiation.  The terms and conditions of the Indebtedness of the Company set forth on Company Disclosure Schedule 6.10 shall be renegotiated on terms and conditions deemed acceptable to REG in its sole discretion, and all such Indebtedness shall be retained or assumed by the Surviving Company and not by Parent.  The Company shall provide such assistance and cooperation as REG, Parent and their Affiliates may reasonably request in connection with the renegotiation of the Indebtedness of the Company, including (a) making senior management of the Company reasonably available for customary syndication presentations and meetings and presentations with rating agencies and lenders or other proposed financing sources and (b) cooperating with prospective lenders or other proposed financing sources in performing their due diligence.

Section 6.11                                Monthly Financial Statements.  As soon as reasonably practicable, but in no event later than forty-five (45) days after the end of each calendar month during the period from the date hereof to the Closing, the Company shall provide Parent with (a) unaudited monthly financial statements, including the balance sheet and related statement of income and cash flows, of the Company (such statements to be prepared by the Company in accordance with GAAP consistent with past practice in each case without footnotes) and (b) operating or management reports (such reports to be in the form prepared by the Company in the Ordinary Course of Business) for such preceding month (such financial statements, the “Company Monthly Financial Statements”).  At or as close to reasonably practicable prior to Closing, Company shall provide Parent with the Final Closing Balance Sheet.  As soon as reasonably practicable, but in no event later than forty-five (45) days after the end of each calendar month (or as soon as practicable if and when such financial statements are received by REG or Parent from the parties to the Common Plan Agreements other than REG) during the period from the date hereof to the Closing, REG and Parent shall provide the Company with unaudited monthly financial statements, including the balance sheet and related statement of income and cash flows, of Parent, MergerLLC, REG and the other respective parties to the Common Plan Agreements (such statements to be prepared in accordance with GAAP consistent with past practice in each case without footnotes) (such financial statements, the “Parent Monthly Financial Statements”); provided, however, the monthly financials for Parent, MergerLLC and REG for the months of February and March, 2009 shall not be required to be delivered until May 26, 2009.

58

Section 6.12                                Notification of Certain Matters.  The Company shall give notice to Parent, and Parent and REG shall give notice to the Company, as promptly as reasonably practicable, upon becoming aware of (a) any fact, change, condition, circumstance, event, occurrence or non-occurrence that has caused or is reasonably likely to cause any representation or warranty in this Agreement made by it or under any of the Common Plan Agreements by any of the other parties thereto to be untrue or inaccurate in any respect at any time after the date hereof and prior to the Closing, (b) any material failure on its part to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder or any of the other parties under any of the other Common Plan Agreements or (c) the institution of or the threat of institution of any Legal Proceeding against the Company, Parent, MergerLLC or REG or any of the other parties under any of the other Common Plan Agreements related to this Agreement or the transactions contemplated hereby; provided, that the delivery of any notice pursuant to this Section 6.12 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice, or the representations or warranties of, or the conditions to the obligations of, the parties hereto.

Section 6.13                                Parent Board of Directors.  On the Closing Date, Parent shall take such actions as are reasonably necessary to elect Ronald L. Mapes as nominee of the Company, to Parent’s Board of Directors, to serve until the expiration of the restrictions set forth in Article X of the Certificate of Incorporation and until his successor is elected and qualified, or if earlier, until his earlier death, resignation or removal.

Section 6.14                                Preparation of the Form S-4 and the Joint Proxy Statement; Unitholder and Stockholder Meetings.

(a)                                  As soon as practicable following the date of this Agreement, the Company, Parent, REG and the other parties to the Common Plan Agreements shall prepare and file with the SEC the Joint Proxy Statement and Parent shall prepare, with the cooperation of the Company, REG and the other parties to the Common Plan Agreements, and file with the SEC the Form S-4, in which the Joint Proxy Statement will be included as a prospectus.  Each of the Company, REG and Parent shall, and shall cause their accountants and lawyers to use its commercially reasonable efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing and keep the Form S-4 effective for so long as necessary to consummate the transactions contemplated by this Agreement, including causing their accountants to deliver necessary or required instruments such as opinions, consents, certificates and comfort letters, each in customary form and covering such matters of the type customarily covered by such documents.  The Company shall use its commercially reasonable efforts to cause the Joint Proxy Statement to be mailed to the unitholders of the Company and REG shall use its reasonable best efforts to cause the Joint Proxy Statement to be mailed or otherwise delivered in accordance with Law to the stockholders of REG, in each case as promptly as practicable after the Form S-4 is declared effective under the Securities Act.  Parent shall also, at Parent’s expense, take any action (other than qualifying to do business in any jurisdiction, other than the state of Illinois, in which it is not now so qualified or filing a general consent to service of process) required to be taken under any applicable state securities Laws in connection with the issuance of shares of Parent Common Stock and Parent Preferred Stock, and the Company shall furnish all information concerning the Company and the unitholders of the

59

Company as may be reasonably requested by Parent in connection with any such action.  No filing of, or amendment or supplement to, the Form S-4 will be made by Parent, and no filing of, or amendment or supplement to, the Joint Proxy Statement will be made by the Company, REG or Parent, in each case without providing the other parties a reasonable opportunity to review and comment thereon.  If at any time prior to the time the Form S-4 is declared effective under the Securities Act any information relating to the Company, REG or Parent, or any of their respective Affiliates, directors or officers, should be discovered by the Company, REG or Parent which should be set forth in an amendment or supplement to either the Form S-4 or the Joint Proxy Statement, so that either such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by Law, disseminated to the unitholders of the Company and the stockholders of REG.  The parties shall notify each other promptly of the receipt of any comments from the SEC or the staff of the SEC and of any request by the SEC or the staff of the SEC for amendments or supplements to the Joint Proxy Statement or the Form S-4 or for additional information and shall supply each other with copies of (i) all correspondence between it or any of its Representatives, on the one hand, and the SEC or the staff of the SEC, on the other hand, with respect to the Joint Proxy Statement, the Form S-4 or the transactions contemplated by this Agreement and (ii) all orders of the SEC relating to the Form S-4.  Preparation of the Form S-4 and the Joint Proxy Statement under this Agreement shall be effectuated in conjunction with the required S-4 and Joint Proxy Statement required under the Related Transactions.

(b)                                 The Company shall, as soon as practicable following the date of this Agreement subject to compliance with SEC requirements and compliance with the requirements of the Company’s operating agreement and applicable Law, establish a record date for, duly call, give notice of, convene and hold a special meeting of its unitholders (the “Company Unitholders Meeting”) for the purpose of obtaining the Company Unitholder Approval.  Subject to Section 6.6(c) hereof, the Company shall, through its Board of Managers, recommend to its unitholders adoption of this Agreement (the “Company Board Recommendation”).  The Joint Proxy Statement shall include a copy of the Company Board Recommendation.  Without limiting the generality of the foregoing, the Company’s obligations pursuant to the first sentence of this Section 6.14(b) shall not be affected by (i) the commencement, public proposal, public disclosure or communication to the Company of any Takeover Proposal or (ii) the withdrawal or modification by the Board of Managers of the Company or any committee thereof of the Company Board Recommendation or such Board of Managers’ or such committee’s approval of this Agreement; provided, further, however, that if the Board of Managers of the Company withdraws or modifies such recommendation due to any reason other than a reason or reasons arising from a Material Adverse Effect with respect to Parent, MergerLLC or REG, the Company shall pay Parent a Termination Fee to the extent provided for in Sections 8.4.

Section 6.15                                Agreements of Rule 145 Affiliates.  At least five (5) Business Days prior to the Closing Date, the Company shall cause to be prepared and delivered to Parent a list identifying all persons who it believes may be deemed to be “affiliates” of the Company, as that

60

term is used in paragraphs (c) and (d) of Rule 145 under the Securities Act (the “Rule 145 Affiliates”).  The Company shall use its commercially reasonable efforts to cause each person who is identified as its Rule 145 Affiliate in such list to deliver to Parent, at or prior to the Closing Date, a written agreement, in substantially the form attached hereto as Exhibit F.  Parent shall be entitled to place restrictive legends on any shares of Parent Common Stock or Parent Preferred Stock issued (i) to such Rule 145 Affiliates and (ii) to any other Persons who it reasonably believes may be deemed to be “affiliates” of the Company, as that term is used in paragraphs (c) and (d) of Rule 145 under the Securities Act, pursuant to the Transaction.

Section 6.16                                Legend.

The Company understands and agrees that each of the certificates evidencing Parent Common Stock and Parent Preferred Stock to be acquired hereunder may bear the following legends:

“THE SALE OR TRANSFER OF SHARES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE RESTRICTIONS IN ARTICLE X OF THE CERTIFICATE OF INCORPORATION OF REG NEWCO, INC. (THE “CORPORATION”), AND ANY AMENDMENTS THERETO, COPIES OF WHICH ARE AVAILABLE WITHOUT CHARGE UPON REQUEST TO THE CORPORATION. THE CORPORATION WILL FURNISH TO THE HOLDER OF THIS CERTIFICATE WITHOUT CHARGE UPON REQUEST A FULL STATEMENT OF THE DESIGNATIONS, PREFERENCES, LIMITATIONS, AND RELATIVE RIGHTS OF THE SHARES OF EACH CLASS OF SHARES AUTHORIZED TO BE ISSUED BY THE CORPORATION.”

Section 6.17                                Employee Benefits.  Parent agrees that, commencing at the Effective Time, the employees of the Company will be provided with benefits under Parent’s then existing employee benefit plans that are comparable, in the aggregate, to the benefits, policies and procedures provided by REG immediately prior to the Closing or employee benefit plans of REG that are assumed by Parent pursuant to the Merger Agreement (collectively, the “Parent Plans”).  Parent will cause any employee benefit plans which the employees of the Company are eligible to participate in to take into account for purposes of eligibility, vesting and benefit accrual thereunder (except for benefit accrual under defined benefit pension plans, for purposes of qualifying for subsidized early retirement benefits or to the extent it would result in a duplication of benefits) service by employees of the Company as if such service were with MergerLLC or Parent, to the same extent such service was credited under a comparable plan of the Company.  Parent shall, and shall cause the Surviving Company to, honor all employee benefit obligations to current and former Employees under the Employee Benefit Plans. Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement shall be construed as requiring any compensation or employee benefit plans, programs or arrangements to continue to be maintained by Parent with respect to Employees for any specified period after the Closing Date.

Section 6.18                                Updating of Schedules.  From time to time prior to the Closing Date, Parent, MergerLLC, REG and the Company shall promptly amend or supplement the Disclosure

61

Schedules to reflect any events or circumstances that occur or arise between the date hereof and the Closing Date and that, if existing or occurring on the date of this Agreement, would have been required to be disclosed on such Schedule in order to make the representations and warranties of the respective party true and correct; provided, however, that no such amendment or supplement made by a party shall have any effect for the purpose of determining the satisfaction of the conditions to the obligations of the other party hereunder or excuse the breach of a covenant by a party hereunder.

Section 6.19                                REG Covenants.  In addition to the covenants made by REG in this Article VI, REG hereby makes and restates herein for the benefit of the Company the covenants and agreements of REG set forth in Sections 6.2 through 6.6, 6.10, 6.11 and 6.14(b) of the REG Merger Agreement.  The Company Disclosure Schedules, as defined in the REG Merger Agreement, provided in connection with such covenants and agreements, shall be delivered by REG to the Company and shall be applicable to such covenants and agreements upon the execution of this Agreement.  No amendment, waiver or consent relating to such covenants and agreements shall be effective for any purpose under this Agreement unless such amendment, waiver or consent is in writing and signed by the Company.

(a)                                  From and after the Effective Time, the Surviving Company shall, to the fullest extent permitted by applicable law, indemnify, defend and hold harmless, and provide advancement of expenses to, each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time, a manager, officer or employee of the Company (the “Indemnified Parties”) against all losses, claims, damages, costs, expenses, liabilities or judgments or amounts that are paid in settlement of or in connection with any claim, action, suit, proceeding or investigation to the extent based on or arising out of the fact that such person is or was a manager or officer of the Company, and pertaining to any matter existing or occurring, or any acts or omissions occurring, at or prior to the Effective Time, whether asserted or claimed prior to, or at or after, the Effective Time (including matters, acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby) (“Indemnified Liabilities”) to the same extent such persons are indemnified and have the right to advancement of expenses as of the date of this Agreement by the Company pursuant to the Company’s Certificate of Formation, Operating Agreement and indemnification agreements, if any, in existence on the date hereof with any managers or officers of the Company, but only to the extent such agreements are listed on Company Disclosure Schedule 6.20(a) (provided that any Person to whom expenses are advanced shall have provided an undertaking to repay such advances if it is ultimately and finally determined after all appeals are exhausted that such Person is not entitled to indemnification).

(b)                                 The Company shall, prior to the Effective Time, purchase a continuation policy for the current policy of managers’ and officers’ liability insurance maintained by the Company on the date of this Agreement, or a substantially similar continuation policy with a substantially comparable insurer at the discretion of the Company, with respect to claims arising from facts or events which occurred at or before the Effective Time.  Such continuation policy shall be

62

effective for a period of five (5) years after the Effective Time, shall be in the amount of $10,000,000, shall provide substantially the same coverage, amounts, retentions, terms and conditions as the Company’s current policy, and shall be purchased at an expense to the Company not to exceed $91,000.  The Surviving Company and Parent shall take no action which would terminate or compromise the continuation of such policy during the term thereof; provided, however, the Surviving Company shall have no obligation to purchase such policy if it is not purchased prior to the Effective Time.

(c)                              The Indemnified Liabilities shall include all expenses, including reasonable fees and expenses of counsel, that an Indemnified Person may incur in enforcing the indemnity and other obligations provided for in this Section 6.20.

(d)                                 The Certificate of Formation and Operating Agreement of the Surviving Company shall contain provisions no less favorable with respect to indemnification and exculpation of individuals who were mangers and officers of the Company prior to the Effective Time than are set forth in the Company’s Certificate of Formation and Operating Agreement as in effect on the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years from the Effective Time in any manner that would adversely affect the rights thereunder of any such individuals, unless such a modification is required by applicable law.  If the Surviving Company or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of the Surviving Company, as the case may be, shall assume the obligations set forth in this Section 6.20.

(e)                                  The provisions of this Section 6.20: (i) are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have or contract or otherwise.

6.21                           Tax Returns.  Parent shall have the exclusive obligation and authority to prepare or cause to be prepared and shall file or cause to be filed all Tax Returns that are required to be filed by the Company after the Closing that include transactions for the period prior to the Closing.  Parent shall prepare or cause to be prepared all such Tax Returns in accordance with past practice except to the extent necessary to comply with the requirements of applicable law.  Parent shall not cause or permit the Company to, and the Company shall not, amend any Tax Return of the Company or any tax election made by the Company that was filed or made before the Closing, or make any election that would change previously filed Tax Returns except as required by applicable law.

TERMINATION

Section 8.1             Termination of Agreement.  This Agreement may be terminated prior to the Closing as follows:

(a)           At the election of Parent, REG or the Company on or after February 28, 2010 (such date, as it may be extended under this Section 8.1(a), the “Termination Date”) if the Closing shall not have occurred by the close of business on such date; provided, that the terminating party is not in material default of any of its obligations hereunder; and provided further, that (A) either Parent, REG or the Company shall have the option to extend, from time to time, the Termination Date for additional periods of time, not to exceed sixty (60) days in the aggregate (or such longer period as Parent, REG and the Company may mutually agree) if all other conditions to the Closing are satisfied or capable of then being satisfied and the sole reason that the Closing has not been consummated is that the condition set forth in Section 6.4 has not been satisfied due to the failure to obtain the necessary consents and approvals under applicable Laws or an Order of a Governmental Authority of competent jurisdiction shall be in effect and Parent, MergerLLC, REG and/or the Company are still attempting to obtain such necessary consents and approvals under applicable Laws, or are contesting (x) the refusal of the relevant Governmental Authority to give such consents or approvals, or (y) the entry of any such Order, in court or through other applicable proceedings; and (B) the right to terminate this Agreement pursuant to this Section 8.1(a) shall not be available to any party whose breach of any provision of this Agreement has been the cause of, or resulted, directly or indirectly, in, the failure of the Closing to be consummated by the Termination Date;

(d)           by Parent, MergerLLC, REG or the Company if there shall be in effect a final nonappealable Order of a Governmental Authority of competent jurisdiction restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated hereby; provided, however, that the right to terminate this Agreement under this Section 8.1(d) shall not be available to a party if such Order was primarily due to the failure of such party to perform any of its obligations under this Agreement;

(e)           by Parent, MergerLLC or REG, if the Company shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or if any representation or warranty of the Company shall have become untrue, in either case such that the conditions set forth in Section 7.1(a) or 7.1(b) would not be satisfied and such breach is incapable of being cured or, if capable of being cured, shall not have been cured within fifteen (15) days following receipt by the Company of notice of such breach from Parent, MergerLLC or REG;

(f)            by the Company, if REG, Parent or MergerLLC shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or if any representation or warranty of REG, Parent or MergerLLC shall have become untrue, or if any of the other parties to the Common Plan Agreements (other than REG) shall have breached its representations, warranties, covenants or agreements or if any representation or warranty of any of the other parties to the Common Plan Agreements (other than REG) shall have become untrue, in any case such that the conditions set forth in Sections 7.2(a), 7.2(b) or 7.2(c) would not be satisfied and such breach is incapable of being cured or, if capable of being cured, shall not have been cured within fifteen (15) days following receipt by Parent, MergerLLC or REG of notice of such breach from the Company;

(g)           by Parent, MergerLLC or REG, if (i) a Company Adverse Recommendation Change shall have occurred or (ii) the Board of Managers of the Company or any committee thereof (x) shall not have rejected any Takeover Proposal within fifteen (15) Business Days of the making thereof (including, for these purposes, by taking no position with respect to the acceptance by the Company’s unitholders of a tender offer or exchange offer, which shall constitute a failure to reject such Takeover Proposal) or (y) shall have failed to publicly reconfirm the Company Board Recommendation within fifteen (15) Business Days after receipt of a written request from Parent or REG that it do so if such request is made following the making by any Person of a Takeover Proposal; or if (iii) a voluntary or involuntary bankruptcy petition shall have been filed by or against the Company and is not discharged within sixty (60) days of the filing thereof;

(h)           by the Company if (i) the Board of Directors of REG withdraws its favorable recommendation as to the Transaction, this Agreement, the REG Merger or the REG Merger Agreement or (ii) a voluntary or involuntary bankruptcy petition shall have been filed by or against REG, Parent or MergerLLC and is not discharged within sixty (60) days of the filing thereof;

(j)            by Parent, MergerLLC, REG or the Company if the Company Stockholder Approval (as defined in the REG Merger Agreement) of the REG Merger Agreement shall not have been obtained at the REG Stockholders Meeting or at any adjournment or postponement thereof; provided, however, that the right of either Parent, MergerLLC or REG to terminate this Agreement under this Section 8.1(j) shall not be available to it if it has failed to comply in all material respects with its obligations under Section 6.14(a) or (b) of the REG Merger Agreement; or

(k)           by Parent, MergerLLC or REG on or before June 15, 2009, if Parent’s Environmental Assessment (as defined in Section 6.9(a)) at the Company’s properties shall have revealed any circumstances that could reasonably be expected to result in (A) the criminal prosecution of the Company or any manager, officer or employee of the Company under Environmental Laws, (B) any suspension or closure of operations at the Company’s properties or facilities or the revocation or termination of any Environmental Permits which has a Material Adverse Effect on the Company or (C) any Environmental Costs and Liabilities that, individually or in the aggregate, will or could reasonably be expected to result in expenditures to cure in excess of the amounts reserved therefor on the Balance Sheet by at least $50,000.

(a) the obligations of the parties set forth in Section 8.4 and Article X hereof shall survive any such termination and shall be enforceable hereunder; and

(b) nothing in this Section 8.3 shall relieve Parent, MergerLLC, REG or the Company of any Liability for a willful breach of this Agreement prior to the effective date of such termination.

Section 8.4             Termination Fee.

(a)           In the event that this Agreement is terminated by Parent, MergerLLC or REG pursuant to Section 8.1(g), then the Company shall pay to REG a termination fee of $1,500,000 in cash.  In the event that this Agreement is terminated by Parent, MergerLLC, REG or the Company pursuant to Section 8.1(i) and (i) the Company agrees to a sale to a third party within twelve (12) months of the Company Unitholder Meeting with such alternative sale proposal

72

generally known to the Company Unitholders prior to the Company Unitholder Meeting, then the Company shall pay to REG a termination fee of $1,500,000 in cash; or (ii) the Company agrees to a sale to a third party within twelve (12) months of the Company Unitholder Meeting, but such alternative sale proposal is not generally known to the Company Unitholders prior to the Company Unitholder Meeting, then the Company shall pay to REG a termination fee of $500,000 in cash.  In the event that this Agreement is terminated by the Company pursuant to Section 8.1(h), then REG shall pay to the Company a termination fee of $1,500,000 in cash, and in the event that this Agreement is terminated by Parent, MergerLLC, REG or the Company pursuant to Section 8.1(j) and (i) REG agrees to a sale to a third party within twelve (12) months of the REG Stockholder Meeting with such alternative sale proposal generally known to the REG stockholders prior to the REG Stockholder Meeting, then REG shall pay to the Company a termination fee of $1,500,000 in cash or (ii) REG agrees to a sale to a third party within twelve (12) months of the REG Stockholder Meeting, but such alternative sale proposal is not generally known to the REG stockholders prior to the REG Stockholder Meeting, then REG shall pay to the Company a termination fee of $500,000 in cash.  Each of the foregoing fees shall herein be referred to as a “Termination Fee.”

(b)           Any payment required to be made pursuant to Section 8.4(a) shall be made promptly following termination of this Agreement (and in any event not later than ten (10) Business Days after delivery of notice of demand for payment).  Any such payments shall be made by wire transfer of immediately available funds to an account to be designated by the receiving party.

(c)           In the event that a party shall fail to pay the Termination Fee required pursuant to Section 8.4 when due, such Termination Fee shall accrue interest for the period commencing on the date such Termination Fee became due, at a rate equal to the rate of interest publicly announced by Citibank, in the City of New York, from time to time during such period, as such bank’s Prime Lending Rate, plus 2%.  In addition, if a party fails to pay such Termination Fee when due, that party shall also pay all of costs and expenses (including attorneys’ fees and related charges) in connection with efforts to collect such Termination Fee.  Each of the parties acknowledges that the Termination Fee and the other provisions of this Article VIII are an integral part of this Agreement and that, without these agreements, the parties would not enter into this Agreement.

(d)           Each of Parent, MergerLLC, REG and the Company acknowledges and agrees that in the event of a breach of this Agreement, the payment of the Termination Fee shall not constitute the exclusive remedy available, and that the parties shall be entitled to the remedies set forth in Section 10.3, including injunction and specific performance, and all additional and other remedies available at law or in equity to which such party may be entitled.

ARTICLE IX
RISK OF LOSS

The risk of loss, damage or destruction to the Company Assets from fire or other casualty or cause, shall be borne by the Company at all times up to the Closing.  It shall be the responsibility of the Company 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,

73

damage or destruction.  In the event of any such loss, damage or destruction, subject to the consent of the Company’s Senior Lender, 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 the conditions stated below.  In the event that property reasonably required for the normal operation of the Business is not repaired, replaced, or restored prior to the Closing, MergerLLC, at its sole option, and as MergerLLC’s sole remedy with respect to any of the foregoing, upon written notice to the Company:  (a) may elect to postpone Closing until such time as the property has been repaired, replaced, or restored, or (b) may elect to consummate the Closing and accept the property in its then condition, together with all proceeds of insurance therefor, covering the property involved; and if MergerLLC 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 VII have been satisfied or waived (other than conditions by their nature are to be satisfied at Closing), MergerLLC may, as its sole right and remedy, terminate this Agreement by giving written notice thereof to the Company, without any party having any Liability or obligation under or in respect of this Agreement.

ARTICLE X
