(a) Merger Consideration.

(i) Company Membership Interests. Each unit of membership interests of the Company issued and outstanding immediately prior to the Effective Time (other than (1) Company Units held by the Company in treasury, (2) Company Units held by REG or any Affiliate of REG, and (3) Company Units owned by the Company or any direct or indirect wholly-owned Subsidiary of the Company, and in each case not held on behalf of third parties (each, an “Excluded Unit” and collectively, “Excluded Units”)) shall be converted into the right to receive 0.4479 shares of Parent Common Stock (the “Common Stock Per Unit Closing Merger Consideration”) and 0.0088 shares of Parent Preferred Stock (the “Preferred Stock Per Unit Closing Merger Consideration”) with those certain preferred rights and designations as set forth in the Series A Preferred Stock Certificate of Designation, a copy of which is attached hereto as Exhibit C.

(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

(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

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

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.

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.

The Company shall not, and shall cause its Representatives not to, directly or indirectly (i) solicit, initiate, cause, facilitate or encourage (including by way of furnishing information) any inquiries or proposals that constitute, or may reasonably be expected to lead to, any Takeover Proposal, (ii) participate in any discussions or negotiations with any third party regarding any Takeover Proposal or (iii) enter into any agreement related to any Takeover Proposal; provided, however, that if after the date hereof the Board of Managers of the Company receives an unsolicited, bona fide written Takeover Proposal made after the date hereof in circumstances not involving a breach of this Agreement, and the Board of Managers of

the Company reasonably determines in good faith that such Takeover 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 the Company’s unitholders under Delaware law, then the Company may, at any time prior to obtaining the Company Unitholder Approval (but in no event after obtaining the Company Unitholder Approval) and after providing Parent not less than two (2) Business Days written notice of its intention to take such actions (A) furnish information with respect to the Company to the Person making such Takeover Proposal, but only after such Person enters into a customary confidentiality agreement with the Company (which confidentiality agreement must be no less favorable to the Company (i.e., no less restrictive with respect to the conduct of such Person) than the Confidentiality Agreement), provided that (1) such confidentiality agreement may not include any provision calling for an exclusive right to negotiate with the Company and (2) the Company advises Parent 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 Company delivers to Parent all such information not previously provided to Parent, and (B) participate in discussions and negotiations with such Person regarding such Takeover Proposal. Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by the Company’s Representatives shall be deemed to be a breach of this Section 6.6 by the Company. The Company shall provide Parent with a correct and complete copy of any confidentiality agreement entered into pursuant to this paragraph within 48 hours after the execution thereof.

(b) In addition to the other obligations of the Company set forth in this Section 6.6, the Company shall promptly advise Parent orally, and within 48 hours advise Parent in writing after receipt, if any proposal, offer, inquiry or other contact is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, the Company in respect of any Takeover Proposal, and shall, in any such notice to Parent, indicate the identity of the Person making such proposal, offer, inquiry or other contact and the terms and conditions of any proposals or offers or the nature of any inquiries or contacts (and shall include with such notice copies of any written materials received from or on behalf of such Person relating to such proposal, offer, inquiry or request), and thereafter shall promptly keep Parent fully informed of all material developments affecting the status and terms of any such proposals, offers, inquiries or requests (and the Company shall provide Parent with copies of any additional written materials received that relate to such proposals, offers, inquiries or requests) and of the status of any such discussions or negotiations.

(c) Except as expressly permitted by this Section 6.6(c), neither the Board of Managers of the Company nor any committee thereof shall (i)(A) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Parent or MergerLLC, the Company Board Recommendation or the approval or declaration of advisability by such Board of Managers of this Agreement and the transactions contemplated hereby or (B) approve or recommend, or propose publicly to approve or recommend, any Takeover Proposal (any action described in this clause (i) being referred to as a “Company Adverse Recommendation Change”) or (ii) approve or recommend, or propose publicly to approve or recommend, or cause or authorize the Company 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 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

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.

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

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

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.

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

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.

(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

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.

(t) the Company shall have approved in writing any material increase in REG’s and Parent’s Liabilities from those reflected on REG’s Balance Sheet, as delivered in response to Section 4.5 of the REG Merger Agreement and Section 5.10 of this Agreement, to those reflected in REG’s Final Closing Balance Sheet, as defined in the REG Merger Agreement and provided by REG to the Company prior to the Closing, and other than Liabilities incurred under loan or credit agreements or arrangements in effect on the date of this Agreement and otherwise in the Ordinary Course of Business;

(u) REG shall have delivered audited financial statements for the fiscal year ended December 31, 2008 to the Company on or before May 31, 2009; provided, however, in the event such audited financial statements, including, without limitation, the balance sheet, income

ARTICLE VIII
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;

(b) by mutual written consent of Parent, MergerLLC, REG and the Company;

(c) by written notice (i) from Parent, MergerLLC and REG to the Company that there has been an event, change, occurrence or circumstance that, individually or in the aggregate, with any other events, changes, occurrences or circumstances, has had or could reasonably be expected to have a Material Adverse Effect on the Company or (ii) from the Company to Parent, MergerLLC and REG that there has been an event, change, occurrence or circumstance that, individually or in the aggregate, with any other events, changes, occurrences or circumstances,

has had or could reasonably be expected to have a Material Adverse Effect on Parent, MergerLLC or REG; provided, however, the failure to close of any of the other Common Plan Agreements other than the REG Merger Agreement shall not be deemed a Material Adverse Effect on Parent, MergerLLC or REG;

(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;

(i) by Parent, MergerLLC, REG or the Company if the Company Unitholder Approval shall not have been obtained at the Company Unitholders Meeting duly convened therefor or at any adjournment or postponement thereof; provided, however, that the right of the Company to terminate this Agreement under this Section 8.1(i) shall not be available to it if it has failed to comply in all material respects with its obligations under Section 6.6 or 6.14(b);

(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.

Section 8.2 Procedure upon Termination. In the event of termination and abandonment by Parent, MergerLLC, REG or the Company, or all, pursuant to Section 8.1 hereof, written notice thereof shall forthwith be given to the other party or parties, and this Agreement shall terminate, and the purchase of the Purchased Assets hereunder shall be abandoned, without further action by Parent, MergerLLC, REG or the Company.

Section 8.3 Effect of Termination. In the event that this Agreement is validly terminated as provided herein, then each of the parties shall be relieved of their duties and obligations arising under this Agreement after the date of such termination and such termination shall be without liability to Parent, MergerLLC, REG or the Company; provided, however, that:

(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

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,

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

Section 10.3 Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

The parties accordingly agree that, in addition to other remedies to which they are entitled at Law or in equity, each party shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction without the necessity of proving the inadequacy of monetary damages as a remedy.

No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Section 10.5 No Third Party Beneficiaries. Except after Closing for the Company Unitholders immediately prior to the Effective Time and except as provided in Section 6.20(e), the representations, warranties and covenants set forth herein are solely for the benefit of the parties hereto, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including, without limitation, the right to rely upon the representations and warranties set forth herein.

No other agreement between or amongst the Members and/or the Company pertaining to such matters shall constitute a portion of the Company’s Operating Agreement. This Agreement and the exhibits and schedules attached hereto may not be modified or rescinded except in a signed, written record and otherwise in accordance with this Agreement.

ARTICLE III

AUTHORIZED UNITS; UNITS OF INITIAL MEMBERS; CERTIFICATES

3.1 Authorized Units. The Company shall have the authority to issue an unlimited number of Units.

3.2 Units and Capital Contributions of Initial Member. The Initial Member has been issued the number of Units in exchange for the Capital Contribution of the Initial Member described on Schedule 1 attached (or to be attached) hereto.

3.3 Certificates; Transferable Interest. Units may be issued with or without certificates as determined and authorized by the Managers from time to time. Any certificates issued for Units shall be in such form as the Managers shall prescribe.

A certificate issued for Units shall represent only the Transferable Interest with respect to the Units represented by such certificate and the transfer of the certificate shall only transfer said Transferable Interest and in no way shall it otherwise transfer any portion of the Membership Interest of a Member who was the original holder or a transferor of the

certificate. The only method by which a Transferee or other Person may obtain a Membership Interest in the Company is to become a Member in accordance with this Agreement.

All Units and certificates shall be issued and held upon and subject to all further terms and conditions of this Agreement.

3.4 Execution of Certificates. All certificates for Units shall be numbered in the order in which they shall be issued and shall be signed by an officer, by and on behalf of the Company, which shall be in such form as shall be determined by the Managers. The signature of an officer upon a certificate may be by facsimile if the certificate is countersigned by a transfer agent, or registered by a registrar, other than the Company itself or an employee of the Company. In case any officer who has signed or whose facsimile signature has been placed upon a certificate for the Company shall have ceased to be a officer before such certificate is issued, the certificate may be issued by the Company with the same effect as if such prior officer were still an officer at the date of issue of the certificate.

3.5 Cancellation. Every certificate surrendered to the Company for exchange or transfer shall be canceled, and no new certificate or certificates shall be issued in exchange for any existing certificate until such existing certificate shall have been so canceled, except in cases provided for in Section 3.6 of this Agreement; provided, however, that the Managers may in all events authorize the issuance of Units without certificates in exchange for any surrendered and canceled certificate. Every certificate surrendered to the Company for transfer shall be properly endorsed for transfer.

3.6 Lost, Destroyed, or Mutilated Certificates. In the event of the loss, theft or destruction of any certificate for any Unit, another may be issued in its place pursuant to such regulations as the Managers may establish concerning proof of such loss, theft or destruction and concerning the giving of satisfactory indemnity or bond or bonds of indemnity.

3.7 Unit Record and Ownership. A record shall be kept by the Company of the names and addresses of all Members and the number of Units held by each Member. The Member in whose name Units stand on the books of the Company shall be deemed the owner thereof for all purposes as regards the Company.

3.8 Transfers of Units. Transfers of Units shall be made only on the books of the Company by the record holder thereof, or by such holder’s attorney thereunto authorized by power of attorney duly executed and filed with the Company, and the payment of all transfer taxes thereon, if any. All Units and all interests represented thereby shall in all events be transferable only upon and subject to the terms and conditions of this Agreement.

3.9 Regulations. The Managers may make such other rules and regulations as they may deem necessary or appropriate concerning the issue, transfer and registration of

Units, so long as such rules and regulations are not inconsistent with the Certificate, this Agreement or applicable law.

3.10 Article 8 Election; Legend. All Units shall be “securities” governed by Article 8 of the Uniform Commercial Code. Delaware shall constitute the local law of the Company’s jurisdiction in its capacity as the issuer of Units.

Any certificate evidencing Units shall bear a legend substantially to the following effect:

“THIS CERTIFICATE EVIDENCES UNITS IN BLACKHAWK BIOFUELS, LLC AND SHALL BE A SECURITY FOR PURPOSES OF ARTICLE 8 OF THE UNIFORM COMMERCIAL CODE. THE UNITS HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. FURTHER, THE SALE, TRANSFER, PLEDGE OR HYPOTHECATION OF THE UNITS IS SUBJECT TO CERTAIN RESTRICTIONS AND CONDITIONS SET FORTH IN THE OPERATING AGREEMENT OF THE COMPANY UNDER WHICH THIS CERTIFICATE IS ISSUED.”

4.3 Reserved.

4.4 Reserved.

4.5 Meeting of all Members. If all of the Members shall meet at any time and place, either within or outside of the state of Delaware, and consent to the holding of a meeting at such time and place, such meeting shall be valid without call or notice, and at such meeting lawful action may be taken.

4.6 Record Date. The record date for the purpose of determining the Members entitled to notice of, or to vote at, any meeting of the Members shall be the date on which notice of the meeting is mailed, or if no notice is required to be given of such meeting, the date of the meeting. A determination of the Members entitled to notice of, or to vote at, any meeting of the Members which has been made as provided in this Section 4.6 shall also apply to any adjournment of such meeting.

4.7 Voting Rights of Members. The Members shall have one vote for each Unit held by them, and shall be entitled to vote on any matter on which the vote of the Members is taken or is required by this Agreement, the Delaware Act or other applicable law.

4.8 Quorum. Members holding at least a majority of the outstanding Units, represented in person or by proxy, shall constitute a quorum at any meeting of the Members. In the absence of a quorum at a meeting of the Members, the Members holding a majority of the outstanding Units represented at the meeting may adjourn the meeting from time to time without further notice. At any such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally noticed.

4.9 Manner of Acting. Except as otherwise provided in this Agreement or the Delaware Act, if a quorum is present, the affirmative vote of the majority of the Units represented at the meeting and entitled to vote on the subject matter shall be the act of the Members, including, but limited to, with respect to the election of Managers.

4.10 Proxies. At all meetings of the Members, a Member may vote in person or by proxy executed in writing by the Member or by a duly authorized attorney-in-fact of the Member. Any such proxy must be filed with the Company before or at the time of the meeting. No proxy shall be valid after eleven (11) months from the date of its execution, unless otherwise expressly provided in the proxy.

4.11 Action by Members Without a Meeting; Telephonic Meetings. Action required or permitted to be taken at a meeting of Members may be taken without a meeting and without notice if the action is evidenced by one or more written consents describing the action taken, signed by Members holding at least ninety percent (90%) of the outstanding Units entitled to vote and delivered to the Managers for inclusion in the minutes or for filing with the Company records. Action taken under this Section 4.11 is effective when a sufficient number of Members to take the action have signed the consent, unless the consent specifies a different effective date. The record date for determining the Members entitled to take action without a meeting shall be the date the first Member signs a written consent. Prompt notice of the taking of action without a meeting by less than unanimous written consent shall be given to those Members who have not consented to the action in writing.

Members may participate in and hold a meeting by means of conference telephone or similar communications equipment by means of which all of the Members participating in the meeting can hear each other, and participation in such meeting shall constitute attendance and presence in person at such meeting, except where a Member participates

in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

A Member may waive any notice required by law or this Agreement if the waiver is in writing and is signed by the Member, and whether before or after the date and time stated in such notice. A waiver of notice shall be equivalent to proper notice as required by law or this Agreement. The attendance of a Member (in person or by proxy) at, or participation in, a meeting shall constitute a waiver of notice of such meeting and of objection to consideration of a particular matter at the meeting that is not within the purpose or purposes described in the meeting notice, unless the Member at the beginning of the meeting or promptly upon arrival objects to holding the meeting or transacting business at the meeting and does not thereafter vote for, or assent to, action taken at the meeting.

ARTICLE V

RIGHTS AND DUTIES OF MEMBERS

5.1 No Liability. A Member does not guarantee the return of any Member’s Capital Contributions or Capital Account, any Distributions to the Members, or a profit for the Members from the operations of the Company. A Member is not personally liable for the acts or omissions of, or any debts, losses, liabilities, duties or obligations of, the Company, except only to the extent of any unpaid Capital Contribution to the Company.

5.2 Members Have No Exclusive Duty to Company. A Member may have other business interests and may engage in other activities in addition to those relating to the Company; provided, however, that this Section 5.2 is not intended to and shall not be construed as waiving, amending, modifying or altering any of the terms or conditions of any other agreement between any Member and the Company which may prohibit, restrict or otherwise limit any interests or activities of the Member. Neither the Company nor any Member shall have any right, by virtue of this Agreement, to share or participate in any such other interests or activities of any of the Members or to the income, proceeds or other benefits derived therefrom; provided again, however, that this Section 5.2 is not intended to, and shall not be construed as, waiving, amending, modifying or altering any of the terms or conditions of any other agreement between any Member and the Company.

5.3 Company Books. The Managers shall maintain and preserve at the principal office of the Company relevant Company documents, including, but not limited to: (i) a current list of the full name and last known business address of each Member; (ii) a

copy of the Certificate and all amendments thereto; (iii) copies of the Company’s federal, state and local income tax returns and reports, if any, for the three most recent years; (iv) a copy of this Agreement and all amendments thereto; and (v) copies of any financial statements of the Company for the three most recent years.

Each Member has the right, for any purpose reasonably related to the Member’s interest as a Member of the Company, and upon reasonable request and during ordinary business hours, to (i) inspect and copy the Company documents referred to above in this Section 5.3 at the Member’s expense, and (ii) obtain from the Managers from time to time upon reasonable demand (a) true and full information regarding the state of the business and financial condition of the Company; (b) promptly after they become available, a copy of the Company’s federal, state and local income tax returns for each year; and (c) other information regarding the affairs of the Company as is just and reasonable.

Notwithstanding anything in this Agreement or otherwise that may appear to the contrary, the rights to information hereunder do not extend to a Transferee.

5.4 Priority and Return of Capital. No Member shall have priority over any other Member, either as to the return of Capital Contributions or Capital Accounts or as to Net Profits, Net Losses or Distributions. This Section 5.4 shall not, however, apply to loans (as distinguished from Capital Contributions) which a Member has made to the Company.

5.5 Resignation of a Member. A Member may not and does not have the power or right to resign from the Company prior to the dissolution and winding up of the Company. This Agreement specifically waives the applicability of any the events causing a person to cease being a Member listed in Section 18-304 of the Delaware Act to the Company and the Members. No Member shall cease to be a Member of the Company because of the occurrence of any act or circumstance, except as provided under Section 9.2 of this Agreement.

5.6 Binding the Company; Delegation of Authority. The actions of less than all the Members shall not bind the Company, except as authorized under this Operating Agreement.

ARTICLE VI

RIGHTS AND DUTIES OF BOARD OF MANAGERS

6.1 General Powers and Qualifications of the Managers. The general conduct of the business and affairs of the Company shall be under the direction of the Board of Managers, except that none of the powers or authority reserved to the Members under Section 4.1 shall be exercised by the Managers. No Manager is required to be an officer or employee or a Member of the Company, or a resident of the state of Delaware. No Manager may delegate to any Person the Manager’s rights and powers to manage and control the business and affairs of the Company, except only as provided in Section 6.12 of this Agreement with respect to the appointment of officers for the Company.

6.2 Number of and Election of Managers; Tenure. The number of Managers of the Company shall be not less than one (1) nor more than nine (9), the exact number within such range to be determined from time to time by the Members. The Managers shall be elected at the annual meeting of the Members to hold office until the next annual meeting. The initial Managers of the Company shall be Brad Albin, Daniel J. Oh, Jeffrey Stroburg, and Nile Ramsbottom. Each Manager shall hold office until his or her successor shall have been elected and qualifies, or until his or her death, resignation or removal.

6.3 Quorum and Manner of Acting. A quorum for a meeting of the Managers shall consist of a majority of the Managers. If at any meeting of the Managers there be less than a quorum present, a majority of the Managers present may adjourn the meeting from time to time until a quorum shall be present. Notice of any adjourned meeting need not be given.

At all meetings of the Managers, a quorum being present, the act of a majority of the Managers present shall be the act of the Managers, unless the vote of a greater number is otherwise affirmatively and expressly required by the Delaware Act or other applicable law.

Any action required or permitted to be taken at a meeting of the Managers may be taken without a meeting and without notice if the action is taken by all of the Managers and if one or more consents in writing describing the action so taken shall be signed by each Manager. Any such written consent shall be effective when the last Manager signs the consent, unless the consent specifies a different effective date. Any such written consent shall be placed in the minute book of the Company or otherwise retained in the records of the Company.

6.4 Meetings of Managers; Place of Meetings. Regular meetings of the Managers shall be held at such place and at such time as the Managers may by resolution fix and determine from time to time. No notice shall be required for any such regular meeting of the Managers.

Special meetings of the Managers shall be held whenever called by the direction of the President (if a President has been appointed by the Managers) or by any one or more of the Managers at the time being in office. Notice of each special meeting shall be given to each Manager at least two (2) days before the date on which the meeting is to be held. Each notice shall state the date, time and place of the meeting. Unless otherwise stated in the notice thereof, any and all business may be transacted at a special meeting.

A Manager may waive any notice required by law or this Agreement if the waiver is in writing and is signed by the Manager, and whether before or after the date and time stated in such notice. A waiver of notice shall be equivalent to notice in due time as required by law or this Agreement. The attendance of a Manager at, or participation in, a meeting shall constitute a waiver of notice of such meeting unless the Manager at the beginning of the meeting or promptly upon arrival objects to holding the meeting or transacting business at the meeting and does not thereafter vote for or assent to action taken at the meeting.

A Manager who is present at a meeting of the Board of Managers at which action on any matter is taken shall be presumed to have assented to the action taken unless the Manager’s dissent is entered in the minutes of the meeting or unless the Manager files a written dissent to the action with the person acting as the secretary of the meeting before the adjournment thereof. No right to dissent shall be available, however, to a Manager who voted in favor of the action.

The Managers may hold their meetings at such place or places, either within or without the state of Delaware, as the Managers may from time to time determine. If no designation of the place for a meeting is made, the place of the meeting shall be the principal office of the Company in the state of Delaware.

A Manager may participate in any meeting by any means of communication, including, but not limited to, telephone conference call, by which all Managers participating may simultaneously hear each other during the meeting. A Manager participating in a meeting by this means is deemed to be present in person at the meeting.

The Managers may adopt rules and regulations for the conduct of their meetings and the management of the Company, so long as such rules and regulations are not inconsistent with the Certificate, this Agreement or applicable law.

6.5 Powers of Board of Managers. Without limiting the generality of Section 6.1, the Managers shall have the power and authority, as a group, on behalf of the Company, to do and perform all acts as may be necessary or appropriate to the conduct of the Company’s business that are not inconsistent with applicable law, the Certificate, this Agreement, or its reservation of certain powers and authority to the Members as set out at Section 4.1.

6.6 No Liability. A Manager does not guarantee the return of any Member’s Capital Contribution or Capital Account, any Distributions to the Members or other Persons or a profit for the Members from the operations of the Company. A Manager is not personally liable for the acts or omissions of, or any debts, losses, liabilities, duties or obligations of, the Company.

6.7 Managers Have No Exclusive Duty to Company. A Manager shall not be required to manage the Company as his or her sole and exclusive function, and, subject to the fiduciary duties of a Manager set forth in this Agreement, a Manager may have other business interests and may engage in other activities in addition to those relating to the Company; provided, however, that this Section 6.7 is not intended to and shall not be construed as waiving, amending, modifying or altering any of the terms or conditions of any other agreement between any Manager and the Company which may prohibit, restrict or otherwise limit any interests or activities of the Manager.

6.8 Fiduciary Duty and Duty of Good Faith. A Manager owes to the Members only the contractual obligation of good faith and fair dealing as set forth in Section 18-1101 of the Delaware Act. All fiduciary duties that the Manager may owe to the Members are hereby expressly eliminated.

Notwithstanding the foregoing, this Section 6.8 is not intended to and shall not be construed as waiving, amending, modifying or altering any of the terms or conditions of any other agreement between any Manager and the Company which may prohibit, restrict or otherwise limit any interests or activities of the Manager.

6.9 Resignation. Any Manager may resign at any time by giving written notice to each of the Members. The resignation of any Manager shall take effect upon receipt of the written notice thereof by any Member or at such later time as may be specified in such notice; and, unless otherwise specified therein, the acceptance of such resignation shall not be necessary to make it effective.

6.10 Removal. At a meeting called expressly for that purpose, any Manager may be removed at any time, with or without cause, by the affirmative vote of the Members holding at least a majority of the outstanding Units.

6.11 Vacancy. Any vacancy occurring for any reason in a Manager position (including, without limitation, through death, removal or resignation) shall be filled by the affirmative vote of the Members holding at least a majority of the outstanding Units. A Manager appointed to fill a vacancy shall serve as a Manager for the unexpired term of his or her predecessor in office or until his or her earlier death, resignation or removal.

6.12 Salary. The salaries, benefits and all other compensation of the Managers, in their capacity as Managers of the Company, shall be fixed from time to time by the affirmative vote of the Members holding at least a majority of the outstanding Units, and no Manager shall be prevented from receiving such salary, benefits or other compensation by reason of the fact that the Manager is also a Member of the Company. By resolution of the Managers, the Managers may be paid their expenses, if any, of attendance at each meeting of the Managers.

6.13 Officers. The Officers of the Company shall be as set out hereafter, with their successors and replacements chosen by the Board of Managers:

President:	Daniel J. Oh
Vice President:	Brad Albin
Secretary:	Natalie Lischer
Treasurer:	Natalie Lischer

In addition to the President, Secretary, and a Treasurer, the Board of Managers may also choose one or more Vice Presidents, assistant officers, and such other officers as may in the discretion of the Board of Managers be appropriate. Any number of offices may be held by the same person, and Managers may be selected to fill one or more offices. The Managers may delegate their day-to-day management responsibilities to any such officers, as determined by the Managers from time to time, and such officers shall have the authority to contract for, negotiate on behalf of and otherwise represent the interests of the Company as so authorized by the Managers. Unless the Managers decide otherwise, if the title is one commonly used for officers of a business corporation formed under the Delaware Business Corporation Act, the assignment of such a title to an individual shall

constitute the delegation to that individual of the authority and duties that are normally associated with that office and that are set forth in the contract or resolution appointing such officer; subject, however, to any specific delegation of authority and duties or specific restriction on the authority and duties as may be made under or set forth in any such contract or resolution. The officers shall, in all events, be subject to the direction and control of the Managers.

Each such officer shall hold office until his or her successor shall have been duly chosen and shall qualify or until his or her death or until he or she shall resign or shall have been removed.

An officer may resign at any time by delivering written notice to the Secretary, or, in the absence of a Secretary, to the President or any one of the Managers. A resignation is effective when the notice is delivered unless the notice specifies a later effective date. Any officer may be removed by the Board of Managers at any time, with or without cause, but such removal shall be without prejudice to the contract rights, if any, of the officer so removed.

6.14 Execution of Documents. The Board of Managers may authorize any officer or officers to negotiate and enter into any agreement or contract and to negotiate, execute and deliver any instrument or document in the name of, and on behalf of, the Company, and such authority may be general or confined to specific instances, except for such actions as are reserved to the Members under Section 4.1 of this Agreement.

ARTICLE VII

CONTRIBUTIONS TO THE COMPANY; UNITS; AND CAPITAL ACCOUNTS

7.1 Issuance of Units to Members. Each Member’s Capital Contribution shall be represented by Units. The Initial Member has previously contributed the Capital Contribution described in Schedule 1 of this Agreement for the number of Units set forth that Schedule. No subsequent Capital Contributions may be required of the Initial Member.

The number of Units issued to any Additional Member, the Capital Contribution for such Units and any other terms and conditions of such issuance shall be determined by the Members. No Member shall have any preemptive or other right to acquire any Units as the Members may from time to time determine to issue to any Person. Each Additional Member shall have all of the rights and be subject to all of the obligations of a Member under this Agreement upon admission as an Additional Member. An Additional Member shall be admitted as a Member of the Company upon receipt by the Company of (i) the Additional Member’s Capital Contribution, and (ii) an executed addendum whereby the Additional Member accepts, adopts, agrees and otherwise becomes a party to this Agreement; or at such earlier or later date as may be specified at the time of acceptance of the Additional Member’s Capital Contribution. No Unit shall be issued until receipt by the Company of the Additional Member’s Capital Contribution therefor. No subsequent Capital

Contributions may be required of any Additional Member unless otherwise agreed at the time of, or as imposed as a condition to, the issuance of Units to such Additional Member.

7.2 Capital Accounts. The Company shall maintain Capital Accounts for the Members in which shall be recorded all Capital Contributions made by each Member. The Capital Accounts shall from time to time be adjusted and shall reflect increases as a result of the Company’s Net Profits or additional Capital Contributions made by the Members and decreases as a result of the Company’s Net Losses and distributions to the Member.

7.3 No Demand of Member Capital. A Member shall not be entitled to demand or receive from the Company the liquidation of the Member’s Units until the Company is dissolved in accordance with this Agreement.

ALLOCATIONS AND INCOME TAX; DISTRIBUTIONS

8.1 Reserved.

8.2 Distributions.

(a) All distributions of cash or other property to the Members shall be made to the Members pro rata based upon the respective number of fully paid Units held by the Members. All such distributions shall only be made in such amounts and at such times as are determined by the vote of the Members from time to time, but subject to Section 8.3 of this Agreement. The date on which the resolution declaring a distribution to the Members is adopted by the Members shall be the record date for the determination of the Members entitled to receive payment of the distribution. All amounts withheld pursuant to the Code or any provisions of foreign, federal, state or local tax law with respect to any payment or distribution to any Member or Members from the Company shall be treated as amounts distributed to the relevant Member or Members pursuant to this Section 8.2. This Section 8.2 is not applicable to distributions payable to the Members upon the dissolution and liquidation of the Company, which distributions are governed by Section 10.2 of this Agreement.

(b) Subject to Section 8.3 below, if requested by a vote of the Members, on or before March 15 of each year, the Company shall have distributed cash to the Members in at least the amount the Company reasonably estimates (assuming maximum federal and state individual tax rates) will equal the federal and state income tax payable by the Members as a consequence of allocation of income of the Company to the Members for the immediately preceding calendar year.

8.3 Limitation Upon Distributions. No distribution shall be declared and paid to any Member pursuant to Section 8.2 of this Agreement if, after the distribution is made: (i) the Company would not be able to pay its debts as they became due in the usual course of business; (ii) the Company’s total assets would be less than the sum of its total liabilities, plus the amount that would be needed (if any), if the Company were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of Members whose preferential rights are superior to the rights of the Members receiving the distribution; or (iii) the payment of the distribution would be a default by the Company under any agreement for borrowed money by the Company, whether after notice, lapse of time or otherwise.

8.4 Interest on and Return of Capital Contributions. No Member shall be entitled to interest on the Member’s Capital Contribution or to the return of the Member’s Capital Contribution, except only as may be otherwise expressly provided in this Agreement.

8.5 Loans to Company. Nothing in this Agreement shall prevent any Member from making secured or unsecured loans to the Company by agreement with the Company.

8.6 Returns and Other Elections. The Managers shall cause the preparation and timely filing of all tax returns required to be filed by the Company pursuant to the Code and all other tax returns deemed necessary and required in each jurisdiction in which the Company does business. Information returns showing the Member’s share of income or loss shall be furnished to the Members when available after the end of the Company’s Fiscal Year, subject to any extensions for filing. All elections permitted to be made by the Company under federal, state or foreign laws shall be made by the Managers.

ARTICLE IX

TRANSFERABILITY OF UNITS; SUBSTITUTE MEMBERS;

ADDITIONAL MEMBERS

9.1 Assignment of Units. Subject to any restrictions on transferability under applicable law or in this Agreement or any separate agreement as may be entered into by or among the Members, a Member may sell, transfer or assign its Units, in whole or in part, or pledge, grant a security interest, lien, or other encumbrance in or against any or all of the Members’ Units. A sale, transfer or assignment of a Unit does not entitle the assignee to participate in the management and affairs of the Company or to become a Substitute Member or to otherwise exercise any rights of a Member (including, without limitation, the right to vote and to receive notice of meetings), but rather shall only be treated as the transfer of the Transferrable Interest with respect to such Unit and the assignee thereof shall be treated as a Transferee (but only after notice of such assignment is provided to the Company), unless and until the assignee also complies with Section 9.2 of this Agreement. The Member assigning the Unit retains the rights of the Member other than the Transferrable Interest and retains all duties and obligations of the Member. Notwithstanding the foregoing or any other term or condition of this Agreement:

(a) No transfer of any Units shall be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Securities Exchange Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Company under the laws of the jurisdiction of its formation, or (iii) cause the Company to be treated as an association taxable as a corporation or otherwise to be taxed as an entity and not as a partnership for federal income tax purposes.

(b) The Managers may prohibit or otherwise impose restrictions on the transfer of Units if they determine that (i) such prohibition or restrictions are necessary to avoid a significant risk of the Company being treated as an association taxable as a corporation or otherwise being taxed as an entity and not as a partnership for federal income tax purposes or (ii) the transfer would or potentially would result in an increase in the number of record holders of the Company.

(c) No Member shall in any event sell, transfer or assign or have the right to sell, transfer or assign a Unit, or any portion thereof, through an established securities market, a secondary market or the substantial equivalent thereof within the meaning of Code Section 7704(b) or Treasury Regulation Section 1.7704-1. In accordance with Treasury Regulation Section 1.7704-1(d)(2), the purchaser, transferee or assignee of any Unit, or any portion thereof, sold, transferred or assigned through the use of a secondary market or the substantial equivalent thereof within the meaning of Code Section 7704(b) or Treasury Regulation Section 1.7704-1, shall not be admitted as a Substitute Member or otherwise accorded any membership rights, including, but not limited to, the right to receive distributions (directly or indirectly) or to acquire an interest in the capital or profits of the Company. No Member shall establish or attempt to establish in the Units an established securities market, a secondary market or the substantial equivalent thereof within the meaning of Code Section 7704(b) or Treasury Regulation Section 1.7704-

(d) No Person shall hold any Units, directly or indirectly, as a nominee on behalf of another Person.

9.2 Right of Assignee to Become a Member. An assignee of a Unit may become a Substitute Member only if the proposed Substitute Member executes an agreement accepting and adopting the terms of the Certificate and this Agreement, and if Members holding a majority of the Units issued and outstanding approve the sale, transfer or assignment to the Substitute Member. A Substitute Member shall be admitted as a Member upon the later to occur of the two (2) events specified in the preceding sentence. An assignee who has become a Substitute Member has, to the extent of the Units assigned, the rights and powers, and is subject to the restrictions and liabilities, of a Member under the Certificate, this Agreement and the Delaware Act. If the assignee purchased or otherwise received all the Units of the transferring Member and the assignee

becomes a Substitute Member under this section, the transferring Member will no longer retain any rights or obligations as a Member of the Company, notwithstanding Section 5.5 of this Agreement.

9.3 Assignments Not in Compliance with this Agreement. An assignee or transferee of Units pursuant to an assignment or other transfer which was not made pursuant to and upon the terms and conditions of this Agreement shall not have any rights whatsoever as a Member (including, without limitation, to receive Distributions, any notices to Members, to vote, or otherwise) unless and until such assignee or transferee has complied with the terms and conditions of this Agreement, and such assignment or other transfer shall be of no force and effect whatsoever unless and until such compliance has been obtained and satisfied.

9.4 Allocations to Assignees and to Additional Members and Substitute Members. No assignee of a Unit, Additional Member or Substitute Member shall be entitled to any retroactive allocation of losses, income or expense deductions incurred by the Company. The Managers may, at their option, at the time an assignee, Additional Member or Substitute Member is admitted, close the Company books (as though the Company’s tax year had ended) or make pro rata allocations of loss, income and expense deductions to the assignee, Additional Member or Substitute Member for that portion of the Company’s Fiscal Year in which the assignee, Additional Member or Substitute Member was admitted, in accordance with the provisions of Section 706(d) of the Code and the Treasury Regulations promulgated thereunder.

ARTICLE X

DISSOLUTION AND TERMINATION

10.1 Dissolution. The Company shall be dissolved upon the occurrence of any of the following events:

(a) At the time or on the happening of an event specified in the Delaware Act Sections 18-801(4) or 18-801(5), the Certificate or this Agreement to cause dissolution, if any; or

(b) Upon the affirmative vote of the Members holding at least a majority of the issued and outstanding Units.

10.2 Distribution of Assets Upon Dissolution. In settling accounts after dissolution, the assets of the Company shall be distributed in the following order:

(a) To creditors, including Members who are creditors (to the extent permitted by law) in satisfaction of the liabilities of the Company, other than for distributions to Members under the Delaware Act;

(b) To the Members and former members of the Company in satisfaction of liabilities for distributions under the Delaware Act;

(c) To the Members in proportion to, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments for the Company’s Fiscal Year in which the liquidation occurs; and then

(d) To the Members, pro rata based upon the respective number of Units held by the Members.

10.3 Certificate of Cancellation. When all debts, liabilities and obligations have been paid and discharged or reasonably adequate provisions have been made therefor and all of the remaining property and assets have been distributed to the Members, a certificate of cancellation shall be executed and filed with the Delaware Secretary of State. Thereafter, the existence of the Company shall cease, except for the purpose of suits, other proceedings and appropriate action as may be expressly provided in the Delaware Act. The Managers shall have authority to distribute any property of the Company discovered after dissolution, convey real estate and take all such other action as the Managers may determine to be necessary or appropriate on behalf of, and in the name of, the Company.

10.4 Winding Up. Except as provided by law, upon dissolution each Member or Transferee shall look solely to the assets of the Company for the return of the Member’s Capital Account. If the Company property remaining after the payment or discharge of the debts and liabilities of the Company is insufficient to return the Capital Account of a Member, or to pay any distributions owed to the Member, such Member shall have no recourse against any of the Company, any Manager or any other Member. Further, no Member shall be required to restore any deficit in the Member’s Capital Account and such deficit shall not be treated as an asset of the Company. The winding up of the affairs of the Company and the distribution of its assets shall be conducted exclusively by the Members or designee(s) thereof, who are hereby authorized to take all actions necessary or appropriate to accomplish such winding up and distribution, including, without limitation, selling any assets of the Company the Members or their designees deem necessary or appropriate to sell.

ARTICLE XI

LIMITATION ON LIABILITY; INDEMNIFICATION

A Manager or Member of the Company shall not be personally liable to the Company or to its (other) Members for money damages for any action taken, or any failure to take action, as a Member or Manager except for liability for any of the following: (i) the bad faith violation of the covenant of good faith and fair dealing; (ii) a financial benefit received by the Member or Manager to which the Member or Manager was not entitled; (iii) a breach of duty under § 18-607 of the Delaware Act (improper distributions); (iv) an intentional infliction of harm on the Company or a Member; or (v) an intentional violation of criminal law. If the Delaware Act or other applicable law is hereafter amended to authorize the further elimination or limitation of the liability of Members or Managers, then the liability of a Member or Manager of the Company, in addition to the limitation on personal liability provided herein, shall be eliminated or limited to the extent of such amendment,

automatically and without any further action, to the maximum extent permitted by law. Any repeal or modification of this provision by the Members of the Company shall be prospective only, and shall not adversely affect any limitation on the personal liability, or any other right or protection, of a Member or Manager of the Company with respect to any state of facts existing at or prior to the time of such repeal or modification.

Each Person, who is or was a Manager or officer of the Company who was or is made a party to or a witness in, or is threatened to be made a party to, or a witness in, any threatened, pending or completed claim, action, suit or proceeding, whether civil, criminal, administrative or investigative (including a grand jury proceeding) and whether formal or informal, by reason of the fact that such Person (i) is or was a Manager or officer of the Company; or (ii) while a Manager or officer of the Company, is or was serving at the request of the Company as a manager, member, director, officer, partner, trustee, employee or agent of another limited liability company, corporation, partnership, joint venture, trust, employee benefit plan or other entity or enterprise, shall be indemnified and held harmless by the Company with respect to such claim, action, suit or proceeding to the maximum extent the Company may indemnify such Person under Section 18-108, and other provisions of, the Delaware Act, as the same now exists or as it may hereafter be amended or changed (but, in the case of any such amendment or change, only to the extent that such amendment or change empowers the Company to provide broader indemnification than said law empowered the Company to provide prior to such amendment or change), including, without limitation, against reasonable costs and expenses (including attorneys’ fees), judgments, fines, penalties (including an excise tax assessed with respect to an employee benefit plan) and amounts paid in settlement actually and reasonably incurred by such Person in connection with such claim, action, suit or proceeding or any appeal thereof; provided, however, that except with respect to proceedings seeking to enforce indemnification under this Article, entitlement to such indemnification shall be conditioned upon the Company being afforded the opportunity to participate directly on behalf of such Person in such claim, action, suit or proceeding or any settlement discussions relating thereto, and with respect to any settlement or other non-adjudicated disposition of any threatened or pending claim, action, suit or proceeding, entitlement to indemnification shall be further conditioned upon the prior approval by the Company of the proposed settlement or other non-adjudicated disposition. Approval or disapproval by the Company of any proposed settlement or other non-adjudicated disposition shall not subject the Company to any liability to, or require indemnification or reimbursement of, any Person who the Company would not otherwise have been required to indemnify or reimburse.

The right to indemnification conferred in this Article shall include the right to payment or reimbursement by the Company of reasonable expenses incurred in connection with any such claim, action, suit or proceeding in advance of its final disposition; provided, however, that the payment or reimbursement of such expenses in advance of the final disposition of such claim, action, suit or proceeding shall be made only upon delivery to the Company of: (i) a written undertaking by or on behalf of the Person claiming indemnification under this Article to repay all amounts so advanced if it shall ultimately be determined that such Person is not entitled to be indemnified under this Article or otherwise, and (ii) a written affirmation of such Person’s good faith belief that such Person has met the applicable

standard of conduct necessary to require indemnification by the Company pursuant to this Article or otherwise.

This Article shall be deemed a contract between the Company and each Person who is a Manager or officer of the Company at any time while this Article and the relevant provisions of the Delaware Act are in effect, and any repeal or modification of the Delaware Act or of this Article shall not adversely affect any rights or obligations then existing with respect to any state of facts then or theretofore existing or any claim, action, suit or proceeding theretofore or thereafter brought or threatened based, in whole or in part, upon any such state of facts.

The Company may, by action of the Managers, provide indemnification to such of the employees and agents of the Company to such extent and to such effect as the Managers shall determine to be appropriate and as otherwise authorized by the Delaware Act, as the same now exists or as it may hereafter be amended.

Except only as may be limited by the affirmative requirements of applicable law, the indemnification and advancement of expenses provided by or granted pursuant to this Article shall not be deemed exclusive of any other rights which a Person seeking indemnification or advancement of expenses may have, hereafter acquire or become entitled to under any statute, provision of the Certificate, this Agreement or another agreement, vote of the Managers or otherwise.

This Article shall be applicable to all claims, actions, suits or proceedings commenced after the effective date hereof, whether arising from acts or omissions occurring before or after the effective date hereof. Each Person who is now serving or who shall hereafter serve as a Manager or officer of the Company shall be deemed to be doing so in reliance upon the rights of indemnification provided for in this Article, and such rights of indemnification shall continue as to a Person who has ceased to be a Manager or officer of the Company, as the case may be, and shall inure to the benefit of the heirs, executors, legal or personal representatives, administrators, and successors of such a Person. If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify each Manager and officer of the Company to the maximum extent permitted by any applicable portion of this Article that shall not have been invalidated.

Notwithstanding anything in this Article to the contrary, the Company shall (except with respect to proceedings initiated to enforce rights of indemnification to which a Person is entitled under this Article or otherwise) indemnify a Person in connection with a claim, action, suit or proceeding (or part thereof) initiated by such Person only if the initiation of such claim, action, suit or proceeding (or part thereof) was authorized by the Managers.

The Company may purchase and maintain insurance, at its expense, to protect itself and any Person who is or was a Manager officer, employee or agent of the Company, or while a Manager or officer of the Company, is or was serving at the request of the Company as a manager, member, director, officer, partner, trustee, employee or agent of another limited liability company, corporation, partnership, joint venture, trust, employee

benefit plan or other entity or enterprise, against any liability asserted against such Person and incurred by such Person in such capacity, or arising out of such Person’s status as such, and whether or not the Company would have the power to indemnify such Person against such liability or eliminate or limit the Person’s liability to the Company for the conduct giving rise to the liability under the provisions of this Article or the Delaware Act. The Company may create a trust fund, grant a security interest and/or use other means (including, without limitation, letters of credit, surety bonds and/or similar arrangements), as well as enter into contracts providing for indemnification to the maximum extent permitted by law and including as a part thereof any or all of the foregoing, to ensure the payment of such sums as may be necessary to effect full indemnification. The Company’s obligation to make indemnification and pay expenses pursuant to this Article shall be in excess of any insurance purchased and maintained by the Company and such insurance shall be primary. To the extent that indemnity or expenses of a Person entitled to indemnification and payment of expenses pursuant to this Article are paid on behalf of or to such Person by such insurance, such payments shall be deemed to be in satisfaction of the Company’s obligation to such Person to make indemnification and pay expenses pursuant to this Article.

CERTIFICATE OF DESIGNATION OF SERIES

AND DETERMINATION OF RIGHTS AND PREFERENCES

SERIES A CONVERTIBLE PREFERRED STOCK

REG NEWCO, INC.

REG Newco, Inc., a Delaware corporation (the “Company”), acting pursuant to Section 151 of the General Corporation Law of Delaware, does hereby submit the following Certificate of Designation of Series and Determination of Rights and Preferences of its Series A Preferred Stock.

FIRST: The name of the Company is REG Newco, Inc.

SECOND: By approval of the Board of Directors of the Company dated , 2009, the following resolutions were duly adopted:

WHEREAS, the Certificate of Incorporation of the Company authorizes preferred stock consisting of sixty million (60,000,000) shares, par value $0.0001 per share, issuable from time to time in one or more series;

WHEREAS, the Board of Directors of the Company is authorized, subject to limitations prescribed by law and by the provisions of Article IV of the Company’s Certificate of Incorporation, to establish and fix the number of shares to be included in any series of preferred stock and the designation, rights, preferences, powers, restrictions and limitations of the shares of such series;

WHEREAS, it is the desire of the Board of Directors to establish and fix the number of shares to be included in a new series of Preferred Stock and the designation, rights, preferences and limitations of the shares of such new series.

NOW, THEREFORE, BE IT RESOLVED that pursuant to Article IV of the Certificate of Incorporation, there is hereby established a series of fourteen million (14,000,000) shares of cumulative convertible preferred stock of the Company designated as the “Series A Preferred Stock” which shall have the rights, preferences, powers, restrictions and limitations set forth as follows.

C-1

1. Relative Seniority. The Series A Preferred Stock shall, with respect to payment of dividends or in the case of redemption, liquidation, dissolution or winding up of the Company, rank (a) senior and prior to the Common Stock of the Company and to any other class or series of capital stock issued by the Company not designated as ranking senior to or pari passu with the Series A Preferred Stock with respect to payment of dividends or in the case of redemption, liquidation, dissolution or winding up of the Company (collectively, the “Junior Stock”); (b) pari passu with any other class or series of capital stock of the Company, the terms of which specifically provide that such class or series shall rank pari passu with the Series A Preferred Stock with respect to payment of dividends or in the case of redemption, liquidation, dissolution or winding up of the Company (such other class or series of capital stock and the Series A Preferred Stock together, the “Parity Stock”); and (c) junior to any other class or series of capital stock of the Company, the terms of which specifically provide that such class or series shall rank senior to the Series A Preferred Stock with respect to payment of dividends or in the case of redemption, liquidation, dissolution or winding up of the Company (the “Senior Stock”).

2. Dividends.

(a) General. The holders of the Series A Preferred Stock shall accrue dividends at the rate of $.88 per share per annum (subject to appropriate adjustments in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares) calculated on the basis of a 360-day year, consisting of twelve 30-day months, and shall accrue on a daily basis from the date of issuance thereof, compounded annually from the date of issuance, whether or not declared and shall be cumulative (the “Accrued Dividends”); provided, however, that except as set forth in Sections 3, 5 and 6, the Company shall be under no obligation to pay such Accrued Dividends; and, provided further, the holders’ right to receive dividends pursuant to this Section 2(a) shall terminate (other than with respect to Accrued Dividends as of the date of conversion) upon the conversion of the shares of Series A Preferred Stock into Common Stock pursuant to Section 5 below. In the event that, during any calendar year, dividends are paid on both the Series A Preferred Stock and the Common Stock, and the amount of dividends each share of Series A Preferred Stock would have received had it been converted into Common Stock on the first day of such calendar year exceeds the amount of dividends per share paid to the holders of Series A Preferred Stock during such year, then, within five (5) business days following the end of such calendar year, the holders of Series A Preferred Stock shall receive an amount per share equal to the difference between the amount of dividends each share of Series A Preferred Stock would have received had it been converted to Common Stock as of the first day of such year and the amount of dividends paid with respect to each share of Series A Preferred Stock during such year (the “Participating Dividend Payment”), and the amount of the Participating Dividend Payment will be subtracted from the Accrued Dividends with respect to each outstanding share of Preferred Stock as of the date the Participating Dividend Payment is made.

(b) Dividends in Arrears. If any Accrued Dividends on the Series A Preferred Stock shall not have been paid, or declared and set apart for payment, the deficiency shall be fully paid or declared and set apart for payment before any dividend (other than dividends on shares of Common Stock payable in shares of Common Stock) shall be paid or declared or set apart for Junior Stock and before any purchase or acquisition of any Junior Stock is made by the

C-2

Company, except the repurchase of Junior Stock from employees of the Company upon termination of employment. At the earlier of: (i) the redemption of the Series A Preferred Stock; (ii) the conversion of the Series A Preferred Stock pursuant to Section 5; or (iii) the liquidation, dissolution or winding up of the Company (including in connection with an Acquisition as defined in Subsection 3(c) below), all Accrued Dividends shall be paid to the holders of record of outstanding shares of Series A Preferred Stock as provided in Section 6 in the event of a redemption of the Series A Preferred Stock, Sections 2(c) or 5, as applicable, in the event of the conversion of the Series A Preferred Stock and Section 3(a) in the event of a liquidation, dissolution or winding up of the Company (including an Acquisition). No accumulation of dividends on the Series A Preferred Stock shall bear interest.

(c) Manner of Payment. Except as set forth in Subsection 5(a) or Subsection 5(b) below, dividends on the Series A Preferred Stock shall be paid in cash at the time specified in Subsection 2(b) above; provided, however, in the event of a conversion pursuant to Subsection 5(a) or Subsection 5(b), as applicable, in which the Company and such holder do not jointly elect to include the amount of Accrued Dividends in the conversion, and such conversion occurs prior to , 2013, then the Company may elect to postpone the cash payment of any or all Accrued Dividends until up to the earliest to occur of (i) a QPO (as defined in Subsection 5(a)(i) below), (ii) the liquidation, dissolution or winding up of the Company (including in connection with an Acquisition deemed to be a liquidation pursuant to Subsection 3(c) below) or (iii) , 2013. When payable hereunder, each dividend shall be mailed to the holders of record of the Series A Preferred Stock as their names and addresses appear on the share register of the Company or at the office of the transfer agent.

(a) Waiver of Dividend. Notwithstanding anything herein to the contrary, the timing or amount of any payment of Accrued Dividends owing to the holders of Series A Preferred Stock hereunder may be waived by the written consent or affirmative vote of the Preferred Supermajority (as hereinafter defined in Section 3(c) below).

3. Liquidation, Dissolution or Winding Up.

(a) General. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, (i) the holders of shares of Series A Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Company available for distribution to its stockholders, after and subject to the payment in full of all amounts required to be distributed to the holders of any Senior Stock, but before any payment shall be made to the holders of Junior Stock by reason of their ownership thereof, an amount equal to $13.75 per share of Series A Preferred Stock (subject to appropriate adjustments in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares) (“Series A Base Value”) plus any and all Accrued Dividends accrued but unpaid thereon (whether or not declared), together with any other dividends declared but unpaid thereon in an amount which together for such Series A Base Value plus Accrued Dividends and any other dividends declared but unpaid thereon shall not exceed $16.50 per share (the “Series A Accreted Value”) and (ii) the holders of previously converted shares of Series A Preferred Stock shall be entitled to be paid out of the assets of the Company available for distribution to its stockholders, after and subject to the payment in full of all amounts required to be distributed to the holders of any Senior Stock, but

C-3

before any payment shall be made to the holders of Junior Stock by reason of their ownership thereof, any accrued and unpaid dividends on such previously converted shares of Series A Preferred Stock, in an amount which does not exceed the Series A Accreted Value less the Series A Base Value. If upon any such liquidation, dissolution or winding up of the Company the remaining assets of the Company available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series A Preferred Stock and the holders of previously converted shares of Series A Preferred Stock the full amount to which they shall be entitled, the holders of Parity Stock shall first share ratably in any distribution of the remaining assets and funds of the Company in proportion to the respective amounts which would otherwise be payable in respect of the Parity Stock held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full, and the holders of previously converted shares of Parity Stock shall then share ratably in any distribution of any remaining assets and funds of the Company in proportion to the respective amounts which would otherwise be payable in respect of any accrued and unpaid dividends on such shares previously held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(b) Participation. After the payment of all preferential amounts required to be paid to the holders of Preferred Stock upon the dissolution, liquidation, or winding up of the Company, all of the remaining assets and funds of the Company available for distribution to its stockholders shall be distributed ratably among the holders of the Common Stock and the holders of the Series A Preferred Stock as if the Series A Preferred Stock has been converted pursuant to Section 5.

(c) Treatment of Consolidations, Mergers, and Sales of Assets. The merger or consolidation of the Company into or with another corporation which results in the exchange of outstanding shares of the Company, the sale of all or substantially all the assets of the Company, or the license of all or substantially all of the assets of the Company, including without limitation any sale (whether by merger or otherwise) of all or substantially all of the assets or the license of all or substantially all of the assets of one or more subsidiaries (the “Subject Subsidiaries”) of the Company if substantially all of the assets of the Company and its subsidiaries taken as a whole are held by the Subject Subsidiaries shall be deemed to be a liquidation, dissolution or winding up of the Company for purposes of this Section, unless the Company’s stockholders of record as constituted immediately prior to any such transaction, by virtue of securities issued as consideration for such transaction hold at least 50% of the voting power of the surviving or acquiring entity in approximately the same relative percentages after such transaction as before (any transaction so deemed to be a liquidation, dissolution or winding up, an “Acquisition”). The amount deemed distributed to the holders of Series A Preferred Stock upon any such merger or consolidation shall be the cash or the value of the property, rights and/or securities distributed to such holders by the acquiring person, firm or other entity; provided, however, that if the holders of at least seventy-five percent (75%) of the then outstanding shares of Series A Preferred Stock that were issued in exchange for shares of the series A, series AA, series B or series BB preferred stock of Renewable Energy Group, Inc. a Delaware corporation (“REG”), pursuant to the Agreement and Plan of Merger dated , 2009 by and among the Company, REG and REG Merger Sub, Inc. (the “Preferred Supermajority”), affirmatively approve by written consent an Acquisition in accordance with Section 4 below and, in connection with such approval, expressly agree in writing that the cash, securities or other property shall be distributed

C-4

among the holders of Preferred Stock and Common Stock in accordance with the applicable agreement or agreements setting forth the terms and conditions of such Acquisition, the holders of Preferred Stock and Common Stock shall be entitled to receive upon the closing of such Acquisition only such amounts as are set forth in such agreement or agreements. The value of such property, rights or other securities shall be determined in good faith by the Board of Directors of the Company, taking into consideration the relevant terms of any underlying transaction documents. In the event the Company continues to exist following an Acquisition, after payment in full of the liquidation preference as provided for in this Section 3, the certificates representing shares of the Series A Preferred Stock issued and outstanding immediately prior to the consummation of the Acquisition shall be cancelled and extinguished and the holders of such shares of Series A Preferred Stock shall have no further rights in the Company.

4. Voting.

(a) Each holder of outstanding shares of Series A Preferred Stock shall be entitled to the number of votes equal to the number of whole shares of Common Stock into which the shares of Series A Preferred Stock held by such holder are convertible (as adjusted from time to time pursuant to Section 5 hereof), at each meeting of stockholders of the Company (and written actions of stockholders in lieu of meetings) with respect to any and all matters presented to the stockholders of the Company for their action or consideration. Except as provided by law, by the provisions of Subsection 4(b) below or by the provisions establishing any other series of Preferred Stock, holders of Series A Preferred Stock and of any other outstanding series of Preferred Stock shall vote together with the holders of Common Stock as a single class.

(b) Protective Provisions. Subject to the rights of series of Preferred Stock that may from time to time come into existence and any contractual agreements or restrictions which may be then in effect in any agreement of stockholders or other organizational document to which the holders of Series A Preferred Stock and the Company may be a party, the approval by written consent of the Preferred Supermajority (in addition to any other applicable stockholder approval requirements required by law) shall be required for the Company to take the following actions:

(i) authorize or issue, or obligate itself to issue, any shares of Preferred Stock or any other equity security on parity with or having a preference over any series of Preferred Stock with respect to dividends, liquidation, redemption or voting, including any security convertible into or exercisable for any such equity security, or authorize any subsidiary to issue any equity security or any such securities convertible or exercisable therefor;

(ii) increase or decrease the number of authorized shares of any series of Preferred Stock;

(iii) amend the Certificate of Incorporation or Bylaws of the Company, including the amendment of the Certificate of Incorporation by the adoption or amendment of any Certificate of Designation or similar document, or amend the organizational documents of any subsidiary, in any such case other than amendments solely to the extent required to authorize

C-5

the issuance of any Junior Stock or any security convertible into or exercisable for any Junior Stock;

(iv) alter or change the rights, preferences or privileges of the shares of any series of the Preferred Stock;

(v) issue, or cause any subsidiary to issue, any indebtedness, other than trade accounts payable and/or letters of credit, performance bonds or other similar credit support incurred in the ordinary course of business, or amend, renew, increase or otherwise alter in any material respect the terms of any indebtedness previously approved or required to be approved by the holders of the Preferred Stock other than the incurrence of debt solely to fund the payment of Accrued Dividends on the Preferred Stock or solely to fund the redemption of the Preferred Stock pursuant to Section 6;

(vi) increase the authorized number of directors constituting the Board of Directors of the Company from fourteen (14) directors;

(vii) redeem, purchase or otherwise acquire (or pay into or set aside for a sinking fund for such purpose) any share or shares of capital stock of the Company; provided, however, that this restriction shall not apply to the repurchase of shares of Preferred Stock pursuant to Section 6 or the repurchase of shares of Junior Stock from employees, officers, directors, consultants or other persons performing services for the Company or any subsidiary pursuant to agreements under which the Company has the option to repurchase such shares at cost upon the occurrence of certain events, such as the termination of employment;

(viii) declare or pay dividends or otherwise make distributions with respect to any shares of capital stock of the Company, other than dividends on the Preferred Stock;

(ix) declare bankruptcy, dissolve, liquidate or wind up the affairs of the Company or any subsidiary;

(x) modify or change the nature of the Company’s business such that a material portion of the Company’s business is devoted to any business other than the business of (A) designing, constructing or operating facilities for biofuels, chemicals or by-products thereof and (B) procurement, manufacturing, selling, distribution, logistics, marketing or risk management related to biofuels, chemicals or by-products thereof;

(xi) make or permit any subsidiary to make any capital expenditure in excess of $500,000 which is not otherwise included in the annual budget previously approved by the Board of Directors of the Company;

(xii) effect any Acquisition;

(xiii) acquire directly or through a subsidiary the stock or any material assets of another corporation, partnership or other person or entity for consideration valued at more than ten percent (10%) of the total assets of the Company as of the most recent month-end

C-6

prior to such acquisition as reflected on the balance sheet of the Company prepared in accordance with generally accepted accounting principles consistently applied; or

(xiv) agree or commit to do any of the foregoing;

provided, however, that nothing in this Section 4(b) shall be deemed to alter any statutory provision entitling a particular class or series of shares to vote as a class or series with respect to such matter.

5. Conversion Rights.

The holders of the Series A Preferred Stock shall have conversion rights as follows (the “Conversion Rights”):

(a) Automatic Conversion.

(i) Each of the issued and outstanding shares of Series A Preferred Stock shall be automatically converted into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Original Series A Issue Price (as defined below), plus (to the extent the Company and such holder jointly elect to include the amount of Accrued Dividends in the conversion) Accrued Dividends, by the Conversion Price (as defined below) in effect at the time of conversion, upon (A) the closing of the sale of shares of Common Stock, at a price per share to the public (before deducting any commissions or other expenses) of at least two times the Original Series A Issue Price (as defined below) (subject to appropriate adjustments in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares), in a firm commitment underwritten public offering pursuant to an effective registration statement on Form S-1 (or any such successor form) under the Securities Act of 1933, as amended (the “Act”), underwritten by a nationally recognized and reputable investment bank, resulting in an aggregate proceeds to the Company of at least $40,000,000 (a “QPO”), or (B) the date specified in a written contract or agreement of the Preferred Supermajority, or (C) if the shares of Common Stock have a closing price on NASDAQ or any national securities exchange in excess of $24.75 per share for ninety (90) consecutive trading days with an average daily trading volume on such trading days of at least US $8,000,000.

(ii) All holders of record of shares of Series A Preferred Stock then outstanding will be given at least 10 days’ prior written notice of the date fixed and the place designated for automatic conversion of all such shares of Series A Preferred Stock pursuant to this Section 5(a). Such notice will be sent by first class or registered mail, postage prepaid, to each record holder of Series A Preferred Stock at such holder’s address last shown on the records of the transfer agent for the Series A Preferred Stock (or the records of the Company, if it serves as its own transfer agent).

C-7

the conversion) Accrued Dividends, by the Conversion Price (as defined below) in effect at the time of conversion. The Conversion Price at which shares of Common Stock shall be deliverable upon conversion of Series A Preferred Stock without the payment of additional consideration by the holder thereof (the “Conversion Price”) shall initially be the Original Series A Issue Price. Such initial Conversion Price, and the rate at which shares of Series A Preferred Stock may be converted into shares of Common Stock, shall be subject to adjustment as provided below.

In the event of a liquidation of the Company, the Conversion Rights shall terminate at the close of business on the first full day preceding the date fixed for the payment of any amounts distributable on liquidation to the holders of Series A Preferred Stock.

(c) Mechanics of Conversion.

(i) In order to convert shares of Series A Preferred Stock into shares of Common Stock in accordance with this Section 5, the holder shall (A) in the event of a conversion pursuant to Subsection 5(a)(i)(B) or Subsection 5(b) (an “Elective Conversion”), provide written notice to the Company that such holder elects to convert all or any number of the shares represented by such certificate or certificates and the date of conversion which notice, if notice is provided after , 2013, must be received by the Company at least sixty (60) days prior to the date selected by the holder for conversion (the “Conversion Notice”), (B) surrender the certificate or certificates for such shares of Series A Preferred Stock at the office of the transfer agent (or at the principal office of the Company if the Company serves as its own transfer agent), and (C) state in writing such holder’s name or the names of the nominees in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. If required by the Company, certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Company, duly executed by the registered holder or his or its attorney duly authorized in writing. The conversion date shall be the date for conversion specified in the Conversion Notice in the case of an Elective Conversion or in any other case on the date of receipt of such certificates by the transfer agent or the Company following the occurrence of the event (other than an Elective Conversion) giving rise to conversion. The Company shall, as soon as practicable after the conversion date, issue and deliver at such office to such holder, or to his nominees, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled, together with cash in lieu of any fraction of a share and, except as provided in Section 2(c), cash in the amount of any Accrued Dividends (through the date one day prior to the date the shares of Series A Preferred Stock were converted) payable in respect of the shares of Series A Preferred Stock converted pursuant to this Section 5.

(ii) The Company shall at all times during which the Series A Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Series A Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Series A Preferred Stock (including any Accrued Dividends). Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value of the shares of Common Stock issuable upon conversion of the Series A Preferred Stock, the Company will take any corporate action which may, in the opinion

C-8

of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock at such adjusted Conversion Price.

(iii) All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate on the applicable conversion date, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor. Any shares of Series A Preferred Stock so converted shall be retired and cancelled and shall not be reissued, and the Company may from time to time take such appropriate action as may be necessary to reduce the number of shares of authorized Series A Preferred Stock accordingly.

(iv) If the conversion is in connection with an underwritten offer of securities registered pursuant to the Act, the conversion may at the option of any holder tendering Series A Preferred Stock for conversion be conditioned upon the closing with the underwriter of the sale of securities pursuant to such offering, in which event the person(s) entitled to receive the Common Stock issuable upon such conversion of the Series A Preferred Stock shall not be deemed to have converted such Series A Preferred Stock until immediately prior to the closing of the sale of securities.

(d) Conversion Price Adjustments of Series A Preferred Stock for Certain Dilutive Issuances, Splits and Combinations.

(i) The Conversion Price of the Series A Preferred Stock, as applicable, shall be subject to adjustment from time to time as follows:

(A) If the Company shall issue, after the date upon which any shares of Series A Preferred Stock were first issued (the “Purchase Date”), any Additional Stock (as defined below) without consideration or for a consideration per share less than the Conversion Price for Series A Preferred Stock in effect immediately prior to the issuance of such Additional Stock, the Conversion Price for such Series A Preferred Stock in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this clause (i)) be adjusted to a price determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including shares of Common Stock deemed to be issued pursuant to subsection 5(d)(i)(E)(1) or (2)) plus the number of shares of Common Stock that the aggregate consideration received by the Company for such issuance would purchase at such Conversion Price; and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including shares of Common Stock deemed to be issued pursuant to subsection 5(d)(i)(E)(1) or (2)) plus the number of shares of such Additional Stock; provided, however, for purposes of such calculation (1) it shall not include any additional shares of Common Stock issuable with respect to shares of Preferred Stock, convertible securities, or exercisable options, warrants or other rights for the purchase of shares of stock or convertible securities, solely as a result of the adjustment of such Series A Conversion Price (or other conversion ratios) resulting from the issuance of Additional Stock causing such adjustment and (2) the grant, issue or sale of Additional Stock consisting of the same class of security, and warrants to purchase such security and notes convertible into such security, issued or issuable at

C-9

the same price at two or more closings within a six month period shall be aggregated and shall be treated as one sale of Additional Stock occurring on the earliest date on which such securities were granted, issued or sold.

(B) No adjustment of the Conversion Price for the Series A Preferred Stock shall be made in an amount less than one cent per share, provided that any adjustments that are not required to be made by reason of this sentence shall be carried forward and shall be either taken into account in any subsequent adjustment made prior to three (3) years from the date of the event giving rise to the adjustment being carried forward, or shall be made at the end of three (3) years from the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in subsections (E)(3) and (E)(4), no adjustment of such Conversion Price pursuant to this subsection 5(d)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment.

(C) In the case of the issuance of Common Stock for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any discounts, commissions or other expenses allowed, paid or incurred by the Company for any underwriting or otherwise in connection with the issuance and sale thereof.

(D) In the case of the issuance of the Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair value thereof as determined in good faith by the Board of Directors irrespective of any accounting treatment, taking into consideration the relevant terms of any underlying transaction documents.

(E) In the case of the issuance (whether before, on or after the applicable Purchase Date) of options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock or options to purchase or rights to subscribe for such convertible or exchangeable securities, the following provisions shall apply for all purposes of this subsection 5(d)(i) and subsection 5(d)(ii):

(1) The aggregate maximum number of shares of Common Stock deliverable upon exercise (assuming the satisfaction of any conditions to exercisability, including without limitation, the passage of time, but without taking into account potential antidilution adjustments) of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subsections 5(d)(i)(C) and (d)(i)(D)), if any, received by the Company upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights (without taking into account potential antidilution adjustments) for the Common Stock covered thereby.

(2) The aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange (assuming the satisfaction of any conditions to convertibility or exchangeability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) for, any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such

C-10

convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration, if any, received by the Company for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by the Company (without taking into account potential antidilution adjustments) upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in subsections 5(d)(i)(C) and (d)(i)(D)).

(3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Company upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof, the Conversion Price of the Series A Preferred Stock to the extent in any way affected by or computed using such options, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities.

(4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price of the Series A Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities that remain in effect) actually issuable upon the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities.

(5) The number of shares of Common Stock deemed issued and the consideration deemed paid therefor pursuant to subsections 5(d)(i)(E)(1) and (2) shall be appropriately adjusted to reflect any change, termination or expiration of the type described in either subsection 5(d)(i)(E)(3) or (4).

(ii) “Additional Stock” shall mean any shares of capital stock issued (or deemed to have been issued pursuant to subsection 5(d)(i)(E)) by the Company after the Purchase Date other than:

(A) Common Stock issued pursuant to a transaction described in subsection 5(d)(iii) hereof;

(B) Shares of Common Stock issuable or issued to employees, consultants, directors, officers, advisors or vendors (if in transactions with primarily non-financing purposes) of the Company or directors of West Central Cooperative, directly or pursuant to a stock option plan, stock purchase or restricted stock plan, or other arrangement or

C-11

agreement approved by the Board of Directors of the Company, in an aggregate amount not to exceed 5,400,000 shares;

(C) Shares of Common Stock issued, issuable or deemed to have been issued by the Company upon conversion of Preferred Stock;

(D) shares of Common Stock issued or issuable (I) in a public offering before or in connection with which all outstanding shares of Preferred Stock will be converted to Common Stock or (II) upon exercise of warrants or rights granted to underwriters in connection with such a public offering;

(E) Shares of Common Stock issued, issuable or deemed to have been issued in connection with the acquisition by the Company of the stock or assets of another corporation, partnership or other entity, provided that such issuances are first approved by the Board of Directors and for purposes other than primarily equity financing for the Company; and

(F) Shares of Common Stock issued, issuable or deemed to have been issued to a vendor, lender or equipment lessor or in connection with strategic or licensing transactions, joint ventures or similar transactions, provided that such issuances are first approved by the Board of Directors (including the affirmative approval of a majority of the directors designated by NGP, Westway and Bunge and the affirmative approval of the director designated by the USBG Group as provided in the Stockholder Agreement dated on or about , 2009 by and between the Company and certain of its stockholders);

(G) The issuance up to 1,313,359 shares of Common Stock upon the exercise of warrants outstanding as of , 2009 at the exercise prices specified therein (subject to anti-dilution adjustments provided therein); and

(H) Shares of Common Stock issued, issuable or deemed to have been issued in connection with any borrowings by the Company, direct or indirect, from financial institutions, whether or not presently authorized, including any type of loan or payment evidenced by any type of debt instrument, provided that such issuances are approved by the Board of Directors (including the affirmative approval of a majority of the directors designated by NGP, Westway and Bunge and the affirmative approval of the director designated by the USBG Group as provided in the Stockholder Agreement dated on or about , 2009 by and between the Company and certain of its stockholders.)

(iii) In the event the Company should at any time or from time to time after a Purchase Date fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of Common Stock (hereinafter referred to as “Common Stock Equivalents”) without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of such record date (or the date of such dividend

C-12

distribution, split or subdivision if no record date is fixed), the Conversion Price of the Series A Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents with the number of shares issuable with respect to Common Stock Equivalents determined from time to time in the manner provided for deemed issuances in subsection 5(d)(i)(E).

(iv) If the number of shares of Common Stock outstanding at any time after a Purchase Date is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Conversion Price for the Series A Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares.

(e) Other Distributions. In the event the Company shall declare a distribution payable in securities of other persons, evidences of indebtedness issued by the Company or other persons, assets (excluding cash dividends) or options or rights not referred to in subsection 5(d)(iii), then, in each such case for the purpose of this subsection 5(e), the holders of the Series A Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of shares of Common Stock of the Company into which their shares of Preferred Stock are convertible as of the record date fixed for the determination of the holders of Common Stock of the Company entitled to receive such distribution.

(f) Recapitalizations. If at any time or from time to time there shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 5 or Section 3) provision shall be made so that the holders of the Series A Preferred Stock shall thereafter be entitled to receive upon conversion of such Preferred Stock the number of shares of stock or other securities or property of the Company or otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 5 with respect to the rights of the holders of such Preferred Stock after the recapitalization to the end that the provisions of this Section 5 (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of such Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable.

(g) No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Section 5 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock against impairment.

C-13

(h) No Fractional Shares and Certificate as to Adjustments.

(i) No fractional shares shall be issued upon the conversion of any share or shares of the Series A Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share (with one-half being rounded upward). The calculation of the number of shares to be issued shall be determined on the basis of the total number of shares of Series A Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion.

(ii) Upon the occurrence of each adjustment or readjustment of the Conversion Price of Series A Preferred Stock pursuant to this Section 5, the Company, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of such series of Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request at any time of any holder of Series A Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth (A) such adjustment and readjustment, (B) the Conversion Price and (C) the number of shares of Common Stock and the amount, if any, of other property that at the time would be received upon the conversion of a share of Series A Preferred Stock.

(i) Notices of Record Date. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, the Company shall mail to each holder of Series A Preferred Stock, at least ten (10) business days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right.

(j) Reservation of Stock Issuable Upon Conversion. The Company shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series A Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Series A Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of Series A Preferred Stock, in addition to such other remedies as shall be available to the holder of Series A Preferred Stock, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation, and shall not, until such action is taken to increase the authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose, issue any shares of Common Stock.

C-14

(k) Notices. Any notice required by the provisions of this Section 5 to be given to the holders of shares of Series A Preferred Stock shall be deemed given if deposited in the United States mail, postage prepaid, and addressed to each holder of record at his address appearing on the books of the Company or by electronic transmission in the manner permitted by the General Corporation Law of the State of Delaware.

(l) Waiver of Adjustment of Conversion Price. Notwithstanding anything herein to the contrary, any downward adjustment of the Conversion Price of any series of Preferred Stock may be waived by the consent or vote of the holders of the majority of the outstanding shares of such series either before or after the issuance causing the adjustment.

6. Redemption of the Preferred Stock.

(a) At any time and from time to time on or after , 2013, the Preferred Supermajority may require, by providing written notice thereof to the Company (a “Redemption Election”), that all or part of the issued and outstanding shares of Preferred Stock be redeemed by the Company out of funds lawfully available therefor; provided, however, that any such redemptions shall be for an aggregate Redemption Price, as defined below, of at least $5,000,000. Within fourteen (14) days following the receipt by the Company of a Redemption Election, the Company shall provide written notice to all holders of Preferred Stock of the Redemption Election (a “Redemption Notice”) which shall set forth the date of such redemption (the “Redemption Date”) and shall allow all other holders of Preferred Stock the opportunity to participate in the redemption transaction by providing written notice to the Company (an “Election Notice”) within ten (10) days following the receipt of the Redemption Notice of such holder’s election to participate and the number and series of shares held by such holder to be redeemed by the Company. The Redemption Date shall be determined by the Company and shall be (i) a date not less than forty-five (45) days and not more than one hundred and eighty (180) days after the date of the Redemption Notice (a “Standard Redemption Date”), or (ii) a date that is more than one hundred and eighty (180) days after the date of the Redemption Election but prior to the date which is eighteen months following such date (a “Delayed Redemption Date”). On the applicable Redemption Date, concurrently with surrender by the holders of the certificates representing such shares to be redeemed, the Company shall, to the extent it may lawfully do so, redeem all issued and outstanding shares of Series A Preferred Stock to be redeemed by paying an amount per share therefor equal to (i) in the event such redemption occurs on a Standard Redemption Date, the greater of (A) the Fair Market Value (as defined in Section 6(d) below) per share of Series A Preferred Stock, as of the date of the Redemption Election or (B) the Series A Accreted Value; or (ii) in the event such redemption occurs on a Delayed Redemption Date, the greater of (x) the Fair Market Value per share of Series A Preferred Stock, as of the date which is sixty (60) days prior to the Delayed Redemption Date, or (y) the Series A Accreted Value, (in each case, the “Redemption Price”). Each holder of Preferred Stock to be redeemed shall surrender to the Company the certificate or certificates representing such shares, in the manner and at the place designated in the Redemption Notice, and thereupon the applicable Redemption Price of such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof and each surrendered certificate shall be cancelled. In the event less than all the shares represented by any such certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. If the Company does not have

C-15

sufficient funds legally available to redeem on any Redemption Date all shares of Preferred Stock to be redeemed on such Redemption Date, (i) the Company shall redeem a pro rata portion of each holder’s redeemable shares of Preferred Stock out of funds legally available therefor, based on the respective amounts which would otherwise be payable in respect of the shares to be redeemed if the legally available funds were sufficient to redeem all such shares, and shall redeem the remaining shares to have been redeemed as soon as practicable after the Company has funds legally available therefore, and (ii) the Company shall use commercially reasonable efforts to obtain sufficient legally available funds in order to effectuate the complete redemption of all shares of Preferred Stock to be redeemed on the Redemption Date as soon as practicable after the Redemption Date.

(b) In the event the Company sets a Delayed Redemption Date, upon written notice to the Company not less than thirty (30) days prior to the Delayed Redemption Date, each holder of shares of Preferred Stock electing to redeem shares pursuant to an Election Notice shall have the right, by written notice to the Company, to revoke their election to have such shares redeemed.

(c) From and after a Redemption Date, all rights of the holders of the shares of Preferred Stock designated for redemption as holders of Preferred Stock (except the right to receive the Redemption Price, without interest, upon surrender of their certificate or certificates) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Company or be deemed to be outstanding for any purpose whatsoever. The shares of Preferred Stock covered by an Election Notice but not redeemed due to the Company’s having insufficient funds legally available for redemption thereof shall remain outstanding and entitled to all the rights and preferences provided herein until redeemed as provided in Section 7(a) above.

(d) For purposes of calculating the Redemption Price, the “Fair Market Value” per share of Series A Preferred Stock, shall be determined in good faith by the Board of Directors (other than those directors affiliated with or nominated by any holder of Preferred Stock that has submitted an Election Notice) as of the applicable date and in making such determination it shall not give consideration to any discount related to shares representing minority interest or related to any illiquidity or lack of marketability of shares arising from restrictions on transfer under applicable federal or state securities laws, but shall take into consideration the rights and preferences of the Preferred Stock. If the holders of a majority of the Preferred Stock to be redeemed disagree with such determination of Fair Market Value, such holders shall provide written notice to the Company thereof (a “Value Dispute”) and the Fair Market Value per share of the Series A Preferred Stock, shall be determined by the following procedures. Each of the Company, on the one hand, and the holders of Series A Preferred Stock submitting the Value Dispute, on the other hand, shall appoint an independent appraiser, each of whom shall independently determine the Fair Market Value per share of Series A Preferred Stock (the “Appraised Values”). If the higher of the Appraised Values is not more than 25% higher than the lower of the Appraised Values, then the Fair Market Value per share will be the average of the two Appraised Values. If the higher of the Appraised Values is more than 25% higher than the lower of the Appraised Values, then the parties shall appoint a third independent appraiser who shall, within thirty (30) days following receipt of the Appraised Values, select one of the two

C-16

7. Sinking Fund.

There shall be no sinking fund for the payment of dividends, or liquidation preferences on the Series A Preferred Stock or the redemption of any shares thereof.

8. Amendment.

This Certificate of Designation constitutes an agreement between the Company and the holders of the Series A Preferred Stock. It may be amended by vote of the Board of Directors of the Company and the written consent of the Preferred Supermajority; provided, however, that nothing in this Section 8 shall be deemed to alter any statutory provision entitling a particular class or series of shares to vote as a class or series with respect to such amendment; provided further, however, any such amendment that would have a material adverse effect on the rights of a particular holder of shares of Preferred Stock provided in this Certificate of Designation, but would not have a similar material adverse effect on all holders of Preferred Stock generally, shall require the consent of such materially adversely affected holder.

1.2 Additional Offices. The Board may at any time establish branch or subordinate offices at any place or places.

ARTICLE 2

Meeting of Stockholders

2.1 Place of Meeting. Meetings of stockholders may be held at such place, either within or without Delaware, as determined by the Board. The Board may, in its sole discretion, determine that the meeting shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Delaware law. If authorized by the board of directors in its sole discretion, and subject to such guidelines and procedures as the board of directors may adopt, stockholders and proxy holders not physically present at a meeting of stockholders may, by means of remote communication: (i) participate in a meeting of stockholders; and (ii) be deemed present in person and vote at a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (A) the Corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxy holder, (B) the Corporation shall implement reasonable measures to provide such stockholders and proxy holders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (C) if any stockholder or proxy holder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the Corporation.

2.2 Annual Meeting. Annual meetings of stockholders shall be held at such date and time as shall be designated from time to time by the Board and stated in the notice of the meeting. At such annual meetings, the stockholders shall elect the members of the Board which shall

be determined by a plurality of votes cast and transact such other business as may properly be brought before the meetings.

2.3 Special Meetings. Special meetings of the stockholders, for any purpose or purposes, may, unless otherwise prescribed by the statute or by the Certificate of Incorporation, be called by the Chairman of the Board or the President and shall be called by the President or Secretary at the request in writing of a majority of the Board or of the holders of shares entitled to cast not less than ten percent (10%) of the votes at the meeting and by additional persons as may be provided in the Certificate of Incorporation or these Bylaws. Such request shall state the purpose or purposes of the proposed meeting. Upon request in writing that a special meeting of stockholders be called for any proper purpose, directed to the Chairman of the Board of Directors, the President, the Chief Executive Officer, the Vice President or the Secretary, by any person (other than the board of directors) entitled to call a special meeting of stockholders, the person forthwith shall cause notice to be given to the stockholders entitled to vote that a meeting will be held at a time requested by the person or persons calling the meeting, such time not to be less than thirty-five (35), nor more than sixty (60), days after receipt of the request. Such request shall state the purpose or purposes of the proposed meeting.

2.4 Notice of Meetings. Written notice of stockholders’ meetings, stating the place, if any, date and time of the meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and the purpose or purposes for which the meeting is called, shall be given to each stockholder entitled to vote at such meeting not less than ten (10), nor more than sixty (60), days prior to the meeting.

When a meeting is adjourned to another place, date or time, written notice need not be given of the adjourned meeting if the place, if any, date and time thereof and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken; provided, however, that if the date of any adjourned meeting is more than thirty (30) days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, written notice of the place, date and time of the adjourned meeting shall be given in conformity herewith. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

2.5 Business Matter of a Special Meeting. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice.

2.6 List of Stockholders. The officer in charge of the stock ledger of the Corporation or the transfer agent shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the principal place of business of the Corporation. In the

event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

2.7 Organization and Conduct of Business. The Chairman of the Board or, in his or her absence, the President of the Corporation or, in their absence, such person as the Board may have designated or, in the absence of such a person, such person as may be chosen by the holders of a majority of the shares entitled to vote who are present, in person or by proxy, shall call to order any meeting of the stockholders and act as Chairman of the meeting. In the absence of the Secretary of the Corporation, the Secretary of the meeting shall be such person as the Chairman appoints.

The Chairman of any meeting of stockholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seems to him or her in order.

2.8 Quorum and Adjournments. Except where otherwise provided by law or in the Certificate of Incorporation or these Bylaws, the holders of a majority of the stock issued and outstanding and entitled to vote, present in person or represented in proxy, shall constitute a quorum at all meetings of the stockholders. The stockholders present at a duly called or held meeting at which a quorum is present may continue to do business until adjournment, notwithstanding the withdrawal of enough stockholders to have less than a quorum if any action taken (other than adjournment) is approved by at least a majority of the shares required to constitute a quorum. At such adjourned meeting at which a quorum is present or represented, any business may be transacted which might have been transacted at the meeting as originally noticed. If, however, a quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat who are present in person or represented by proxy shall have the power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented.

2.9 Voting Rights. Unless otherwise provided in the Certificate of Incorporation, each stockholder shall at every meeting of the stockholders be entitled to one vote in person or by proxy for each share of the capital stock having voting power held by such stockholder.

2.10 Majority Vote. When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which, by express provision of the statutes or of the Certificate of Incorporation or of these Bylaws, a different vote is required, in which case such express provision shall govern and control the decision of such question.

2.11 Record Date. For purposes of determining the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or to exercise any rights in respect of any change, conversion, or exchange of stock or for the purpose of any lawful action, the Board may fix, in advance, a record date which shall not be more than sixty (60), nor less than ten (10), days prior to the date of such meeting, nor more than sixty (60) days prior to the date of any other action. A determination of stockholders of record entitled to notice or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for the adjourned meeting.

If the Board does not so fix a record date, (i) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the business day next preceding the day on which notice is given or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held and (ii) the record date for any other purpose shall be the close of business at the Corporation’s principal office on the day on which the Board adopts the resolution relating to such purpose.

2.12 Proxies. Every person entitled to vote for directors or on any other matter shall have the right to do so either in person or by one or more agents authorized by a written proxy signed by the person and filed with the Secretary of the Corporation. A proxy shall be deemed signed if the stockholder’s name is placed on the proxy (whether by manual signature, typewriting, telegraphic transmission, electronic transmission or otherwise) by the stockholder or the stockholder’s attorney-in-fact. A validly executed proxy which does not state that it is irrevocable shall continue in full force and effect unless (a) revoked by the person executing it, before the vote pursuant to that proxy, by a writing delivered to the Corporation stating that the proxy is revoked or by a subsequent proxy executed by the maker of the proxy, or by that person’s attendance and vote at the meeting; or (b) written notice of the death or incapacity of the maker of that proxy is received by the Corporation before the vote pursuant to that proxy is counted; provided, however, that no proxy shall be valid after the expiration of eleven months from the date of the proxy, unless otherwise provided in the proxy.

2.13 Inspectors of Election. Before any meeting of stockholders, the Board may appoint any person other than nominees for office to act as inspectors of election at the meeting or its adjournment. If no inspectors of election are so appointed, the Chairman of the meeting may, and on the request of any stockholder or a stockholder’s proxy shall, appoint inspectors of election at the meeting. The number of inspectors shall be either one (1) or three (3). If inspectors are appointed at a meeting on the request of one or more stockholders or proxies, the holders of a majority of shares or their proxies present at the meeting shall determine whether one (1) or three (3) inspectors are to be appointed. If any person appointed as inspector fails to appear or fails or refuses to act, the Chairman of the meeting may, and upon the request of any stockholder or a stockholder’s proxy shall, appoint a person to fill that vacancy.

necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted, and shall be delivered to the Corporation by delivery to its registered office, its principal place of business, or an officer or agent of the corporation having custody of the book in which proceedings of meetings or stockholders are recorded. A telegram, cablegram or other electronic transmission consenting to an action to be taken and transmitted by a stockholder or proxyholder, or by a person or persons authorized to act for a stockholder or proxyholder, shall be deemed to be written, signed and dated for the purposes of this Section to the extent permitted by law.

Directors

3.1 Number; Qualifications; Election. The authorized number of directors shall initially be not less than one (1) nor more than fourteen (14), the exact number within such range to be determined by the Board, but no reduction in the number of directors shall have the effect of reducing the terms of office of any directors then in office. All directors shall be elected at the annual meeting or at any special meeting of the stockholders, except as provided in Section 3.2 hereof, and each director so elected shall hold office until the next annual meeting or any special meeting, or until his successor is elected and qualified, or until his earlier resignation or removal. Directors need not be stockholders.

3.2 Resignation and Vacancies. A vacancy or vacancies in the Board shall be deemed to exist in the case of the death, resignation or removal of any director, or if the authorized number of directors is increased. Vacancies may be filled by a majority of the remaining directors, though less than a quorum, or by a sole remaining director, unless otherwise provided in the Certificate of Incorporation. The stockholders may elect a director or directors at any time to fill any vacancy or vacancies not filled by the directors. If the Board accepts the resignation of a director tendered to take effect at a future time, the Board shall have power to elect a successor to take office when the resignation is to become effective. If there are no directors in office, then an election of directors may be held in the manner provided by statute.

Except as otherwise required by statute, notice of each special meeting shall be given to each director, if by mail, when addressed to him or her at his or her residence or usual place of business, unless he or she shall have filed with the Secretary a written request that notices intended for him or her be mailed to some other address, in which case it shall be mailed to the address designated in such request, on at least two (2) days’ notice prior to the time of the meeting, or shall be sent to him or her at such place by telegram, radiogram or cablegram, or other electronic means, or delivered to him or her personally, not later than four (4) hours before the time the meeting is to be held. Unless otherwise indicated in the notice thereof, any and all business may be transacted at a special meeting.

3.9 Quorum and Adjournments. At all meetings of the Board, a majority of the total number of the whole Board shall constitute a quorum for the transaction of business, and the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board, except as may otherwise be specifically provided by law or by the Certificate of Incorporation. If a quorum is not present at any meeting of the Board, the directors present may adjourn the meeting from time to time, without notice other than announcement at the meeting at which the adjournment is taken, until a quorum shall be present. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors, if any action taken is approved of by at least a majority of the required quorum for that meeting.

3.10 Action Without Meeting. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a meeting, if all members of the Board or committee, as the case may be, consent thereto in writing or by electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board or committee. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

3.11 Telephone Meetings. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any member of the Board or of any committee may participate in a meeting by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

3.12 Waiver of Notice. Notice of a meeting need not be given to any director who signs a waiver of notice or provides a waiver by electronic transmission or a consent to holding the meeting or an approval of the minutes thereof, whether before or after the meeting, or who attends the meeting without protesting, either prior thereto or at its commencement, the lack of notice to such director. All such waivers, consents and approvals or any waiver by electronic transmission shall be filed with the corporate records or made a part of the minutes of the meeting.

3.13 Fees and Compensation of Directors. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, the Board shall have the authority to fix the compensation of directors. The directors may be paid their expenses, if any, of attendance at each meeting of the Board, and may be paid a fixed sum for attendance at each meeting of the Board or a stated salary as director. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending committee meetings.

3.14 Rights of Inspection. Every director shall have the absolute right at any reasonable time to inspect and copy all books, records and documents of every kind, and to inspect the physical properties of the Corporation and also of its subsidiary corporations, domestic or foreign. Such inspection by a director may be made in person or by agent or attorney, and includes the right to copy and obtain extracts.

3.15 Action with Respect to Securities of Other Corporations. Unless otherwise directed by the Board, the President or any officer of the Corporation authorized by the President shall have power to vote and otherwise act on behalf of the Corporation, in person or by proxy, at any meeting of stockholders of or with respect to any action of stockholders of any other corporation in which this Corporation may hold securities and otherwise to exercise any and all rights and powers which this Corporation may possess by reason of its ownership of securities in such other corporation.

For purposes of this Section 6.1, a “director” or “officer” of the Corporation includes any person (a) who is or was a director or officer of the Corporation, (b) who is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, or (c) who was a director or officer of a corporation which was a predecessor corporation of the Corporation or of another enterprise at the request of such predecessor corporation; provided, however, that, except with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such director or officer in connection with a proceeding (or part thereof) initiated by such director of officer only if such proceeding (or part thereof) was authorized by the Board.

6.2 Indemnification of Others. The Corporation shall have the power, to the maximum extent and in the manner permitted by the General Corporation Law of Delaware, to indemnify each of its employees and agents (other than directors and officers) against expenses (including attorneys’ fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was an agent of the Corporation. For purposes of this Section 6.2, an “employee” or “agent” of the Corporation (other than a director or officer) includes any person (a) who is or was an employee or agent of the Corporation, (b) who is or was serving at the request of the Corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, or (c) who was an employee or agent of a corporation which was a predecessor corporation of the Corporation or of another enterprise at the request of such predecessor corporation.

Expenses incurred in defending any action or proceeding for which indemnification is required pursuant to Section 6.1 hereof, or for which indemnification is permitted pursuant to Section 6.2 hereof, following authorization thereof by the Board, shall be paid by the Corporation in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of the indemnified party to repay such amount, if it shall ultimately be determined that the indemnified party is not entitled to be indemnified as authorized in this Article 6.

6.4 Indemnity Not Exclusive. The indemnification provided by this Article 6 shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office, to the extent that such additional rights to indemnification are authorized in the Certificate of Incorporation.

6.5 Insurance. The Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power to indemnify him or her against such liability under the provisions of the General Corporation Law of Delaware.

6.6 Conflicts. No indemnification or advance shall be made under this Article 6, except where such indemnification or advance is mandated by law or the order, judgment or decree of any court of competent jurisdiction, in any circumstance where it appears:

(a) That it would be inconsistent with a provision of the Certificate of Incorporation, these Bylaws, a resolution of the stockholders or an agreement in effect at the time of the accrual of the alleged cause of the action asserted in the proceeding in which the expenses were incurred or other amounts were paid, which prohibits or otherwise limits indemnification; or

(b) That it would be inconsistent with any condition expressly imposed by a court in approving a settlement.
