This Membership Interest Purchase Agreement (this “Agreement”) is made and entered into as of May 20, 2014, by and among Renewable Energy Group, Inc., a Delaware corporation (“Parent”), REG Synthetic Fuels, LLC, an Iowa limited liability company and wholly-owned subsidiary of Parent (“Purchaser”), and Tyson Foods, Inc., a Delaware corporation (“Seller”). Parent, Purchaser and Seller are each sometimes referred to herein individually as a “party” and collectively as the “parties.” Capitalized terms used and not otherwise defined herein have the meanings set forth in Article XI.

RECITALS

WHEREAS, Parent, Purchaser and Syntroleum Corporation, a Delaware corporation (“Syntroleum”), are parties to that certain Asset Purchase Agreement, dated as of December 17, 2013 (the “Syntroleum Purchase Agreement”), pursuant to which Purchaser has agreed to acquire substantially all of the assets of Syntroleum, including 50% of the membership interests in Dynamic Fuels, LLC, a Delaware limited liability company (the “Company”), owned by Syntroleum;

WHEREAS, Seller owns 50% of the membership interests in the Company (“Seller’s Interest”);

WHEREAS, conditioned upon and subject to consummation of the closing under the Syntroleum Purchase Agreement (the “Syntroleum Closing”) and the other conditions set forth herein, Purchaser desires to purchase from Seller, and Seller desires to sell to Purchaser, Seller’s Interest; and

WHEREAS, concurrently with the execution of this Agreement, the parties hereto are entering into certain other agreements with respect to the Company, including an Agreement, Consent and Release; a Letter of Intent for a Management, Operations and Service Agreement; and a Letter of Credit Reimbursement and Indemnity Agreement;

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

ARTICLE I

PURCHASE AND SALE

1.1 Purchase and Sale of Membership Interests; Repayment of Indebtedness.

(a) At the Closing, subject to the terms and conditions of this Agreement, Seller shall sell, assign, transfer and convey to Purchaser free and clear of all Encumbrances, and Purchaser shall purchase, acquire and accept from Seller, all of Seller’s right, title and interest in and to

***

Seller’s Interest, and Purchaser shall pay to Seller the Closing Purchase Price (the “Membership Purchase”). The total consideration that Purchaser will pay to Seller for Seller’s Interest shall be equal to (a) the Closing Purchase Price, plus (b) all Earnout Payments, if any.

(b) Simultaneous with or immediately following the Closing, Purchaser shall cause the Company to repay all principal outstanding at the Closing under the Tyson Note and Seller shall deliver to Purchaser the Tyson Note for cancellation.

1.2 Earnout.

(a) Subject to all of the following provisions of this Section 1.2, Purchaser shall cause the Company to pay Seller in cash, at the time or times specified in Section 1.2(f), the following amounts (each, an “Earnout Payment”):

(i) with respect to each Initial Earnout Period, an amount equal to the product of (A) $*** multiplied by (B) the number of gallons of DF Product Sold by the Company during such Initial Earnout Period; and

(ii) with respect to each Subsequent Earnout Period, an amount equal to the product of (A) $*** multiplied by (B) the number of gallons of DF Product Sold by the Company during such Subsequent Earnout Period.

(b) Notwithstanding anything in this Section 1.2 to the contrary, in no event shall Purchaser be required to cause the Company to make any Earnout Payment to Seller pursuant to Section 1.2(a) if the sum of all Earnout Payments made to Seller pursuant to this Section 1.2, plus the sum of all amounts setoff as indemnification of Purchaser pursuant to Section 9.7, would exceed thirty-five million dollars ($35,000,000). At its election, Purchaser may at any time satisfy all of its obligations under this Section 1.2 by the payment to Seller in cash of an amount equal to $35,000,000 less the sum of all previous payments under this Section 1.2, any amount set forth in a Claim Notice delivered in good faith that is pending final determination in accordance with Article IX hereof (which will be paid in accordance of the terms of Article IX to the extent resolved in favor of Seller), and all amounts setoff as indemnification of Purchaser pursuant to Section 9.7.

(c) If, during the Earnout Term, the Company makes any capital investments in the Geismar Facility that result in an increase in the Geismar Facility production capacity above seventy-five million (75,000,000) gallons per year, then the total number of gallons of DF Product that may be utilized in the calculation of an Earnout Payment under Section 1.2(a) shall not exceed 18.75 million gallons of DF Product for any calendar quarter (or a proportionately lesser amount for any Earnout Period involving less than a calendar quarter).

(d) If, during the Earnout Term, Purchaser determines that an RFS2 Event has occurred, then Purchaser shall provide written notice thereof and a reasonably detailed statement of the reasons for such determination to Seller and, for a period of 18 months immediately following such RFS2 Event, the amount per gallon to be paid pursuant to Section 1.2(a) shall be reduced from $*** per gallon or $*** per gallon, as applicable, to $*** per gallon of DF Product Sold during such period. If Seller objects to Purchaser’s determination, Seller shall deliver to Purchaser a statement setting forth a reasonably detailed statement of its good faith

***

objections thereto (an “RFS2 Objection Statement”). Purchaser and Seller shall negotiate in good faith to resolve any dispute as to whether an RFS2 Event occurred. If Purchaser and Seller do not reach a final agreement within thirty (30) days after the delivery of the RSF2 Objection Statement, Purchaser or Seller may submit such dispute to the Referee. The parties shall furnish to the Referee Purchaser’s notice that an RFS2 Event has occurred and the RFS2 Objection Statement, and (from time to time as requested by the Referee) such other information and documents as the Referee may reasonably request in order for the Referee to decide whether an RFS2 Event has occurred. The Referee shall make such decision and shall deliver a written notice of the Referee’s decision to Purchaser and Seller within thirty (30) days after such matter is referred to the Referee. The Referee’s decision shall be final and binding on and shall not be appealable by the parties hereto. With respect to any Earnout Payments payable pursuant to Section 1.2(a) during the period between the delivery of an RFS2 Objection Statement and delivery of the Referee’s decision, payments shall be made at the $*** per gallon rate. In the event the Referee determines that an RFS2 Event has not occurred, then Purchaser shall, within two (2) Business Days of Referee’s delivery of notice of such determination, cause the Company to wire to an account specified by Seller immediately available funds in an amount equal to the Earnout Payment(s) that would have been paid in the absence of an RFS2 Event, less the amount paid to Seller during such period(s) following Seller’s improper notice of an RFS2 Event. The fees and expenses of the Referee shall be paid by (i) Seller if the Referee determines that an RSF2 Event has occurred contrary to the RFS2 Objection Statement, or (ii) Purchaser if the Referee determines that an RSF2 Event has not occurred contrary to the notice of the RFS2 Event provided by Purchaser.

(e) As promptly as practicable following, and in any event by the date which is twenty (20) Business Days following the end of each Earnout Period, Purchaser shall cause the Company to prepare and deliver to Seller a statement certified by an executive officer of the Company setting forth the number of gallons of DF Product Sold during such Earnout Period and Purchaser’s calculation of the Earnout Payment payable with respect to such Earnout Period, such statement to be in the form attached hereto as Exhibit A (each an “Earnout Payment Statement”). Upon receipt from the Company of an Earnout Payment Statement for any given Earnout Period, Seller may request and, if so requested, Purchaser shall cause the Company to provide, such documentation and other information as Seller may reasonably request in support of the information set forth in such Earnout Payment Statement. Except as contemplated by this Agreement, the Earnout Payment Statement and the contents thereof shall be held in strict confidence by Seller and shall not be used by Seller for any purpose other than as set forth herein. Purchaser shall provide prompt notice of any corrections to the Earnout Payment Statement discovered after delivery thereof and Purchaser and Seller shall adjust the amount of any Earnout Payment made prior to the correction, subject to Seller’s right to object in accordance with the provisions of this Section 1.2.

(f) Earnout Payments shall be due and payable as follows:

(i) If Seller has any good faith objections to an Earnout Payment Statement, Seller shall deliver to Purchaser a statement setting forth in reasonable detail its good faith objections thereto (an “Earnout Objections Statement”). The Earnout Objections Statement, if any, shall contain a reasonably detailed description of the basis for the objections and the adjustments that Seller believes should be made to the Earnout

Payment Statement. The Earnout Objections Statement must be delivered to Purchaser within fifteen (15) days after delivery of such Earnout Payment Statement. If an Earnout Objections Statement is not delivered to Purchaser within such period, the Earnout Payment contained in the Earnout Payment Statement shall be final and binding on and non-appealable by the parties hereto. To the extent an Earnout Objections Statement is timely delivered to Purchaser, (A) Purchaser shall cause the Company to pay to Seller any portion of the Earnout Payment that is not in dispute and (B) Purchaser and Seller shall negotiate in good faith to resolve any disputed amount (and to the extent such objections in the Earnout Objections Statement are so resolved by mutual written agreement, the Earnout Payment contained in the Earnout Payment Statement shall be adjusted as so resolved and shall thereupon be final and binding on and non-appealable by the parties hereto). If Purchaser and Seller do not reach a final agreement within thirty (30) days after the delivery of the Earnout Objections Statement, Purchaser or Seller may submit such dispute to the Referee. The parties shall furnish to the Referee the Earnout Payment Statement and the Earnout Objections Statement and (from time to time as requested by the Referee) such other information and documents as the Referee may reasonably request in order for the Referee to resolve the dispute. The Referee shall resolve all disputed items and shall deliver a written determination to Purchaser and Seller within thirty (30) days after such matter is referred to the Referee. The resolution of the dispute by the Referee shall be final and binding on and non-appealable by the parties hereto. The fees and expenses of the Referee shall be allocated to and paid by Seller based upon the percentage that the portion of the disputed amount not resolved in the favor of Seller bears to the total amount actually contested by Seller, as determined by the Referee, and the remaining fees and expenses, if any, shall be allocated to and shall be paid by Purchaser, along with any additional amount owing to Seller pursuant to Section 1.2(a), as determined by the Referee.

(ii) If Seller does not have any objections to an Earnout Payment Statement, Seller may deliver to Purchaser a statement setting forth its agreement therewith, and Purchaser, within two (2) Business Days of receipt of Seller’s statement, shall cause the Company to wire to an account specified by Seller immediately available funds in the amount of the Earnout Payment reflected in such Earnout Payment Statement.

(g) Purchaser’s obligation to cause the Company to make the Earnout Payments is subject to Purchaser’s right to withhold and setoff against the Earnout Payments pursuant to Section 9.7 hereof and to defer payment of any amounts set forth in a Claim Notice delivered in good faith before any Earnout Payment is due until such time as a final determination of the claim set forth therein in accordance with Article IX hereof.

(h) Seller acknowledges and agrees that after the Closing Date, the Geismar Facility shall be operated and maintained by the Company, and controlled by the Purchaser, autonomously in accordance with the Company’s and Purchaser’s business judgment, subject only to the qualification that Purchaser shall not, and Purchaser shall cause the Company not to, take any unreasonable or inappropriate action in the operation of the Geismar Facility for the primary purpose of frustrating or diminishing the amount of any Earnout Payment to Seller. Seller further acknowledges and agrees that the Company’s operation and maintenance, and the

Purchaser’s control, of the Geismar Facility will be affected by many factors which could affect volumes of DF Product that are Sold and therefore the amount of any Earnout Payment could fluctuate or even be reduced to zero in any given Earnout Period or over the course of the entire Earnout Term. Subject to Purchaser’s and Company’s compliance with the first sentence of this Section 1.2(h), such factors may include, but are not limited to: Requirements of Law, downtime for both planned and unplanned maintenance or construction at the Geismar Facility, force majeure, operating results that are not acceptable to Purchaser in its business judgment, and labor, vendor, customer and supplier issues or disputes.

(i) The obligations of Purchaser and the Company to make Earnout Payments under this Section 1.2 shall terminate and be of no further force or effect if (x) the Company, pursuant to or within the meaning of any Bankruptcy Law (i) commences a voluntary case that is not withdrawn by the Company or not dismissed by the applicable bankruptcy court as a bad faith filing (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a custodian of it or for all or substantially all of its property, or (iv) makes a general assignment for the benefit of its creditors (including Seller, if Seller is a creditor), or (y) a court of competent jurisdiction enters an order of decree under any Bankruptcy Law that (i) is for relief against the Company in an involuntary case, (ii) appoints a custodian of the Company or for all or substantially all of the Company’s property or (iii) orders the liquidation of the Company.

1.3 The Closing. The closing of the transactions contemplated by this Agreement (the “Contemplated Transactions”) shall take place via facsimile or electronic mail to the extent possible, and otherwise at the offices of Pillsbury ▇▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇ LLP, Four ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇, at 10:00 a.m., Pacific Time, no later than the second Business Day following full satisfaction or waiver of all of the closing conditions set forth in Article VII hereof (other than those to be satisfied at the Closing) or on such other date and in such location as is mutually agreed upon in writing by Purchaser and Seller (the “Closing”). The date and time of the Closing are referred to herein as the “Closing Date.”

1.4 Closing Transactions.

(a) Seller shall execute and deliver, or cause to be delivered, to Purchaser at Closing:

(i) an assignment of Seller’s Interest, free and clear of all Encumbrances, in form satisfactory to Purchaser;

(ii) evidence satisfactory to Purchaser that Seller has obtained the consents set forth in Section 1.4(a)(ii) of the Seller Disclosure Schedules and that such consents do not alter in any material respect the terms of the Company’s obligations under the related Permits or Contracts under which such consent is sought;

(iii) resignations of Seller’s representatives on the Management Committee of the Company or serving as officers of the Company, to be effective upon the Closing;

(iv) an officer’s certificate or other evidence reasonably satisfactory to Seller that all waiting periods under the HSR Act have expired;

(v) such other agreements, instruments or documents as may be reasonably necessary to carry out the Contemplated Transactions and to comply with the terms hereof; and

(vi) each of the other certificates and other documents contemplated to be delivered by Seller to Purchaser under Article VII.

(b) Purchaser shall execute and deliver, or cause to be delivered, to Seller at Closing:

(i) by wire transfer of immediately available funds to an account designated by Seller in writing to Purchaser at least two (2) Business Days prior to the Closing, the Closing Purchase Price;

(ii) such other agreements, instruments or documents as may be reasonably necessary to carry out the Contemplated Transactions and to comply with the terms hereof; and

(iii) each of the other certificates and other documents contemplated to be delivered by Purchaser to Seller under Article VII.

1.5 Parent Guaranty. Parent hereby unconditionally guarantees to the Seller (a) the obligation of Purchaser to pay when due the Closing Purchase Price and the obligation of the Company to pay each Earnout Payment, if applicable, in accordance with this Agreement, (b) the obligation of the Purchaser to cause the Company to pay the Earnout Payments, if applicable, when due, and (c) all of the Purchaser’s other obligations under this Agreement (collectively, the “Guaranteed Obligations”), such that if the Guaranteed Obligations are not paid or performed by Purchaser when due or required, Parent will promptly (but in no event more than two (2) Business Days following the written demand of Seller), pay or cause the performance of the Guaranteed Obligations. The liability of Parent on this guaranty shall be continuing, direct and immediate and not conditional or contingent upon the pursuit of remedies against Purchaser and separate actions may be brought against both Purchaser and Parent. If (i) the ownership interest in the Company is transferred from the Purchaser to another Affiliate of the Parent, (ii) the Company is merged into an Affiliate of the Purchaser, (iii) the majority of the assets comprising the Geismar Facility are transferred to another Affiliate of the Parent, or (iv) any other similar transaction involving an Affiliate of the Parent occurs, then the obligations of this Agreement shall be assigned to such Affiliate and the guaranty provided under this Section 1.5 shall apply to such Affiliate as it applies to the Purchaser.

1.6 Withholding. Purchaser shall be entitled to deduct and withhold from the Closing Purchase Price, any Earnout Payment and any other payments contemplated by this Agreement such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are withheld pursuant to this Section 1.6, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made. At the Closing, Seller will provide any forms or certificates Purchaser may reasonably request in order to satisfy withholding obligations under any applicable Tax law.

2.1 Corporate Organization. Seller is a duly organized and validly existing corporation in good standing under the Laws of the State of Delaware, with all requisite corporate power and authority to own its properties and conduct its business as currently conducted, except where the failure to be so qualified and in good standing would not prevent or delay the Closing.

(b) The execution, delivery and performance of this Agreement by Seller and the consummation of the Contemplated Transactions by Seller does not and will not require any consent, approval, authorization or permit of, or filing with or notification to, any Governmental Authority, except for (i) compliance with and filings under the HSR Act and (ii) any such consent, approval, authorization, permit, filing, or notification the failure of which to make or obtain would not prevent or materially delay the consummation of the Contemplated Transactions.

Schedule 2.3(c) contains a list of all amendments to the Company Operating Agreement.

2.4 Brokers and Finders.

At the Closing, Seller shall deliver to Purchaser good and valid title to Seller’s Interest, free and clear of any Encumbrances.

2.6 Litigation. There is no Proceeding pending or, to the Knowledge of Seller, threatened against Seller which would adversely affect Seller’s performance under this Agreement or the consummation of the Contemplated Transactions.

3.1 Corporate Organization. Each of Parent and Purchaser is a duly organized and validly existing organization in good standing under the Requirements of Law of its jurisdiction

of formation, with all requisite entity power and authority to own its properties and conduct their respective businesses as currently conducted, except where the failure to be so qualified and in good standing would not prevent or delay the Closing. All of the issued and outstanding equity interests in Purchaser are owned directly or indirectly by Parent.

3.2 Authority for this Agreement. Each of Parent and Purchaser has all requisite entity power and authority to execute and deliver this Agreement and to consummate the Contemplated Transactions. The execution and delivery of this Agreement by Parent and the consummation of the Contemplated Transactions have been duly and validly authorized by all necessary corporate proceedings on the part of Parent and no other corporate proceedings on the part of Parent are necessary to authorize this Agreement or to consummate the Contemplated Transactions. The execution and delivery of this Agreement by Purchaser and the consummation by Purchaser of the transactions contemplated hereby have been duly and validly authorized by the Board of Directors of Purchaser and no other corporate proceedings on the part of Purchaser are necessary to authorize this Agreement or to consummate the Contemplated Transactions. This Agreement has been duly and validly executed and delivered by each of Parent and Purchaser and, assuming due authorization, execution and delivery by Seller, constitutes a legal, valid and binding obligation of each of Parent and Purchaser enforceable against each of Parent and Purchaser in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Requirements of Law of general applicability relating to or affecting creditors’ rights and to general equity principles.

3.3 Consents and Approvals; No Violation.

(a) Neither the execution and delivery of this Agreement by Parent or Purchaser nor the consummation of the Contemplated Transactions will, assuming the agreements to be entered into concurrently with this Agreement have been executed and are enforceable against the other parties thereto, (i) violate or conflict with or result in any Breach of any provision of the respective organizational documents of Parent or Purchaser, (ii) assuming all consents, approvals and authorizations contemplated by Section 3.3(b) have been obtained and are effective, all applicable waiting periods have expired and all filings described in such clauses have been made, conflict with or violate any Requirements of Law binding upon Parent or Purchaser or any of their respective assets or properties, or (iii) violate or conflict with or result in a Breach of any provision of, or require any consent, waiver or approval, or result in a default or result in the loss of benefit under, or give rise to any right of termination, cancellation, modification or acceleration (or an event that, with the giving of notice, the passage of time or otherwise, would constitute a default or give rise to any such right) under any of the terms, conditions or provisions of any Contract to which Parent or Purchaser is a party or by which Parent or Purchaser or any of its or their respective properties or assets may be bound, except in the case of clauses (ii) and (iii), which would not prevent or materially delay the consummation of the Contemplated Transactions.

(b) The execution, delivery and performance of this Agreement by each of Parent and Purchaser and the consummation of the Contemplated Transactions by each of Parent and Purchaser do not and will not require any consent, approval, authorization or permit of, or filing with or notification to, any Governmental Authority, except for (i) compliance with and filings under the HSR Act and (ii) any such consent, approval, authorization, permit, filing, or notification the failure of which to make or obtain would not prevent or materially delay the consummation of the Contemplated Transactions.

3.4 Brokers and Finders.

3.5 Litigation. There is no Proceeding pending or, to the Knowledge of Parent and Purchaser, threatened against Parent or Purchaser which would adversely affect Parent or Purchaser’s performance under this Agreement or the consummation of the Contemplated Transactions.

3.6 Investment Intention. The Membership Purchase is for Purchaser’s own account, for investment purposes only and not with a view to the distribution (as such term is used in Section 2(11) of the Securities Act) thereof. Purchaser understands that Sellers’ Interest has not been registered under the Securities Act and cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available.

3.7 Financial Capacity. The payment of the Closing Purchase Price is not conditioned on the receipt by Purchaser or Parent of proceeds of any third-party financing. Assuming the satisfaction of the conditions to Purchaser’s obligation to perform hereunder (including, without limitation, the financing condition set forth in Section 7.2(f) hereof) and the performance by Seller of the obligations under this Agreement, Purchaser and/or Parent will have at the Closing sufficient funds available to pay the Closing Purchase Price in accordance with this Agreement.

3.8 Solvency. Neither Parent nor Purchaser is entering into the Contemplated Transactions with the actual intent to hinder, delay or defraud either present or future creditors of the Company. Subject to the accuracy of the representations and warranties in Article IV, after giving effect to the Contemplated Transactions the Parent and Purchaser do not, as of the date hereof, intend for the Company to incur additional debt beyond its projected ability to pay principal and interest on such additional debt as it becomes due.

The Company is duly qualified and in good standing as a foreign entity authorized to do business in each of the jurisdictions in which the character of the properties owned, leased or operated by it or the conduct of the business transacted by it makes such qualification necessary, except where the failure to be so qualified and in good standing has not had and is not reasonably likely to have a Material Adverse Effect. The Company does not own or hold, has never held or owned, and does not hold or own a right to acquire any stock, partnership interest or joint venture interest or other equity ownership interest in any other Person. Section 4.1 of the Seller Disclosure Schedules sets forth with respect to the Company: (i) all Management Committee Members and officers, (ii) all bank, payroll and securities brokerage accounts and all authorized signers for each such account; and (iii) any powers of attorney granted to any Person that are currently in effect.

4.2 Capitalization. The authorized and outstanding membership interests of the Company are held of record as indicated in Section 1.2 of the Seller Disclosure Schedules, and all such membership interests have been validly issued and are fully paid and nonassessable. There are no outstanding options, warrants, scrip, rights to subscribe to, purchase rights, calls or commitments of any character whatsoever relating to, or securities or rights convertible into, any shares of capital stock or securities containing any equity features of the Company, or contracts, commitments, understandings or arrangements, by which the Company is or may become bound to issue additional equity interests or options, warrants, scrip, rights to subscribe to, purchase rights, calls or commitments of any character whatsoever relating to, or securities or rights convertible into, any equity interests in the Company except as described in the Company Operating Agreement.

4.3 Consents and Approvals; No Violation.

(b) The execution, delivery and performance of this Agreement by the Seller and the consummation of the Contemplated Transactions by the Company does not and will not require any consent, approval, authorization or permit of, or filing with or notification to, any Governmental Authority, except for (i) compliance with and filings under the HSR Act, and (ii) any such consent, approval, authorization, permit, filing, or notification the failure of which to make or obtain would not prevent or materially delay the consummation of the Contemplated Transactions.

The Financial Statements are based on the books and records of the Company, and fairly present in all material respects the financial condition and results of operations of the Company for the periods indicated. The Company maintains a standard system of accounting established and administered in accordance with GAAP.

4.5 Absence of Certain Changes. Since March 31, 2014:

(a) The Company has maintained the Geismar Facility in stand-by mode consistent with past practice, and Seller has not approved the Company to take, permit or suffer, nor to Seller’s Knowledge has the Company taken, permitted or suffered any action or occurrence that, if taken, permitted or suffered after the date hereof, would not be permitted under Section 5.1 hereof. There has not occurred a Material Adverse Effect.

(b) The Company has not sustained any damage, destruction or loss by reason of fire, explosion, earthquake, casualty, labor trouble (including but not limited to any claim of wrongful discharge or other unlawful labor practice), requisition or taking of property by any government or agent thereof, windstorm, embargo, riot, act of God or public enemy, flood, accident, revocation of license or right to do business, total or partial termination, suspension, default or modification of Contracts, governmental restriction or regulation, other calamity, or other similar or dissimilar event (whether or not covered by insurance) that has resulted or is reasonably likely to result in a Material Adverse Effect.

4.6 Related Party Transactions; Loans and Guarantees. Except as contemplated by this Agreement: (a) there are no material transactions or series of related transactions, agreements, arrangements or understandings, which involve any current or future obligations, nor are any such transactions or series of related transactions currently proposed, between the Company and its Affiliates; (b) the Company has not made any loan to any Person which is outstanding in whole or in part, and the Company has not guaranteed the payment of any loan or debt of any Person pursuant to which the Company has or could have any current or future obligation, except for travel or similar advances made to employees in connection with their

4.7 Insurance. Section 4.7 of the Seller Disclosure Schedules sets forth a true and complete list of (a) all liability and other insurance policies insuring the Company against losses arising out of or related to the businesses of the Company (and accurately describes the coverage carried and expiration dates of such policies) and all key man life insurance policies owned or maintained by the Company; and (b) a list of all pending claims under each such policy. All such policies are in full force and effect and are valid, outstanding and enforceable, and all premiums due thereon have been paid. No such policy will terminate or lapse (or be affected in any other materially adverse manner) by reason of the Contemplated Transactions. To Seller’s Knowledge, the Company has complied in all material respects with the provisions of each policy under which it is the insured party, and all material claims under such policies have been filed in a timely fashion. No insurer under any insurance policy has canceled or generally disclaimed liability under any such policy or, to the Seller’s Knowledge, indicated any intent to do so or not to renew any such policy, and no event specific to the Company has occurred which could reasonably be expected to result in a material retroactive upward adjustment in premiums under any such insurance policies or which could reasonably be expected to result in a material prospective upward adjustment in such premiums.

4.8 Employee Matters.

(a) The Company has complied in all material respects with every Requirement of Law relating to the hiring, employment, retention, termination, and classification of employees and service providers including, without limitation, provisions thereof relating to wages, overtime, hours, equal opportunity, mandatory or protected leaves of absence, meal and rest periods, record-keeping, reasonable accommodation, confidentiality, occupational health and safety, the verification requirements and the recordkeeping requirements of the Immigration Reform and Control Act of 1986 or its successor (“IRCA”) and collective bargaining.

(b) The Company is not and has not been delinquent in payments to any employee for any wage, salary, commission, bonus or other compensation for any services performed by them to date, amounts required to be reimbursed to such employees, or amounts that must be paid to an employee upon termination of employment in any material respect; (ii) the Company has withheld, remitted and reported all amounts required by law or by agreement to be withheld,

remitted or reported with respect to the wages, salaries and other payments to employees; (iii) there are no pending, or, to Seller’s Knowledge, threatened Proceedings or investigations by any Person alleging or involving any potential Liability arising out of, based on, or resulting from any violation or alleged violation, of any applicable Law related to employment, working conditions or other aspects of the relationship between an the Company on the one hand and any employee or service provider on the other hand; (iv) no unfair labor practice complaint or action has been asserted against the Company before the National Labor Relations Board or any other Governmental Authority; (iii) the Company is not a party to any labor contract, collective bargaining agreement, letter of understanding, or any other arrangement, formal or informal, with any labor union or organization; (v) no labor union currently represents, or has represented, the employees of the Company; (vi) the Company is not the subject of any proceeding seeking to compel it to bargain with any labor union; (vii) within the last three (3) years there has not been or, to Seller’s Knowledge, threatened, any labor union organizing activities, labor strike, dispute, walkout, work stoppage, slow-down or lockout involving the Company; and (ix) no employee or other service provider of the Company has made an unresolved formal or informal complaint that, if true, would constitute a material violation of any Law.

(c) To Seller’s Knowledge, no employee or other service provider of the Company is bound by any agreement with any other Person that is violated or breached by such individual performing the services that he or she is currently performing for the Company. Every employee of the Company and each of its Subsidiaries is employed on an at-will basis and no employee has a Contract with the Company that would interfere with the ability of the Company to discharge any such employee at any time for any reason without any financial consequence.

4.9 Employee Benefit Plans. For purposes of this Section 4.9, the term “Company” shall include any Person organized under the laws of the United States or operating therein that is or would be aggregated with the Company and its Subsidiaries under Section 414(b), (c), (m), or (o) of the Code (an “ERISA Affiliate”).

No payment made or to be made under a 409A Plan is or will be subject to any taxes or penalties imposed by Code Section 409A. No stock option, stock appreciation rights or other equity based compensation awards issued or to be issued by the Company (each, an “Equity Award”) shall be subject to the requirements of Code Section 409A and the issuance of all Equity Awards shall be supported by a valuation that is entitled to the presumption of reasonableness provided by Treasury Regulation I.409A-l(b)(5)(iv)(b)(2)(i). All existing 409A Plan documents are in full compliance with the requirements of Code Section 409A and do not require any amendments or modifications to achieve compliance with Code Section 409A.

(q) Section 4.9 of the Company Disclosure Schedule sets forth the amount of any payments that are required to be made by the Company at or prior to the Closing or that the Company may be required to make at or following the Closing pursuant to any agreement to which any director or officer of the Company is a party on the date hereof, by reason of the consummation of the transactions contemplated by this Agreement and assuming that such agreement has not been modified, terminated or superseded at the time of the Closing, setting forth the name of the applicable officer or director, and the amount of the payment obligation that would be payable to such officer or director.

4.10 Litigation. As of the date hereof, there is no litigation, claim, action, suit, Proceeding, arbitration, mediation or investigation by a Governmental Authority or other Person pending or, to Seller’s Knowledge, threatened in writing against or relating to the Company or any properties or assets of the Company. As of the date hereof, neither the Company, nor any of its respective properties or assets is or is subject to any Order, writ, judgment, injunction, decree or award that individually or, with respect to related matters, in the aggregate, would, or would reasonably be expected to result in Damages payable to or by the Company or any of its Subsidiaries in an amount, individually or, with respect to related matters, in the aggregate, in excess of $10,000 for any uninsured matter, and in excess of $50,000 for any insured matter.

4.11 Tax Matters.

(a) Tax Returns. The Company has timely filed (or has had timely filed on its behalf) in the manner prescribed by applicable laws all Tax Returns required to be filed by it. All such Tax Returns filed are complete and accurate in all material respects. The Company is currently not the beneficiary of any extension of time within which to file any Tax Return. No written claim has been made by any taxing authority in a jurisdiction where the Company does not file Tax Returns that the Company is or may be subject to taxation by that jurisdiction. The Company has not had or maintained a “permanent establishment” other than in the country of its formation.

(b) Payment of Taxes. All Taxes due and owing by the Company (whether or not shown on any Tax Return) have been timely paid in full. All Liabilities for unpaid Taxes of the Company for positions or periods through March 31, 2014 are properly reserved in the

Company’s balance sheet in accordance with GAAP as of such date (rather than in any notes thereto). The Company has not incurred any Liability for unpaid Taxes accruing after March 31, 2014 except for Taxes arising in the ordinary course of business subsequent to March 31, 2014.

(c) Disputes or Claims; Audits. There is no dispute, claim, controversy, audit or pending audit concerning any Tax liability or Tax Return of the Company claimed, conducted or raised by any Governmental Authority, in respect of which the Company has received a written notice from any such Governmental Authority or to which Seller has Knowledge. Section 4.11 of the Seller Disclosure Schedules lists all Income Tax Returns filed with respect to the Company for taxable periods ended on or after January 1, 2011 or with respect to which the statute of limitations remains open, indicates those of such Income Tax Returns that have been audited, and indicates those of such Income Tax Returns that currently are the subject of audit (in each case, to the extent the Company has been delivered a written notice from the applicable Governmental Authority regarding such audit or otherwise has knowledge of such audit). No issue has been raised in writing by any examination conducted by any Governmental Authority of the Company that, by application of the same principles, might result in a proposed deficiency for any other period not so examined. The Company has not waived any statute of limitations in respect of Taxes or agreed to any extension of time with respect to a Tax assessment or deficiency, which waiver or extension has not lapsed or expired, as applicable.

(d) Liens. There are no Liens for Taxes (other than statutory liens for Taxes not yet due and payable) on any of the assets of the Company.

(f) Tax Sharing Agreements. Except for the Company Operating Agreement, the Company is not a party to or bound by any Tax allocation, Tax indemnity, Tax sharing agreement or similar agreement or arrangement with respect to Taxes (“Tax Sharing Agreement”) nor does the Company have any Liability for Taxes to another party under such agreement.

(g) No FIRPTA Withholding. Seller is not a “foreign person” within the meaning of Section 1445 of the Code and Seller will furnish Purchaser with an affidavit that satisfies the requirements of Code Section 1445(b)(2), in form and substance acceptable to Purchaser.

(h) Withholding. The Company has complied with all applicable Laws relating to the payment, reporting and withholding of Taxes (including withholding of Taxes pursuant to Sections 1441, 1442, 1445, 1446, 3121, 3402 and 3406 of the Code or any comparable provision of any state, local or foreign law) and has, within the time and in the manner prescribed by applicable Law, withheld from and paid over to the proper Governmental Authorities all amounts required to be so withheld and paid over under applicable Laws (including federal and state income Taxes, Federal Insurance Contribution Act, Medicare, Federal Unemployment Tax Act, relevant state income and employment Tax withholding laws), and has timely filed all withholding Tax Returns, for all periods through and including the Closing Date.

(i) Disclosure. Seller has delivered or made available to Purchaser for inspection (i) complete and correct copies of all Tax Returns of the Company for all Taxable periods for which the applicable statute of limitations has not yet expired, and (ii) complete and correct copies of all Tax rulings (including private letter rulings), revenue agent reports, information document requests, notices of proposed deficiencies, deficiency notices, protests, petitions, closing agreements, settlement agreements, advance pricing agreements, pending ruling requests, transfer pricing studies, gain recognition agreements, offers in compromise, valuation studies and any similar documents (including any agreement with any Governmental Authority), submitted by, received by, assessed against or agreed to by or on behalf of the Company. The Company has disclosed on its federal income Tax Returns all positions taken therein that could, if not so disclosed, give rise to any penalties under Section 6662 of the Code or any comparable provisions of state, local or foreign Law. No election has been made with respect to Taxes of the Company that have not been disclosed in writing to the Purchaser or included in Tax Returns made available to Purchaser.

(j) Miscellaneous. The Company does not have (i) nexus, or taken any action that could result in it having nexus, for any Tax purpose in any jurisdiction other than the United States (with respect to any such entity formed in any of the United States) or the jurisdiction of its formation (with respect to any such entity formed outside of the United States), or (ii) has been or has owned (whether directly or indirectly) an interest in, a passive foreign investment company within the meaning of Section 1297 of the Code. The Company has complied with all information reporting and record keeping requirements under all applicable law, including retention and maintenance of required records with respect thereto. The Company does not have nor has it ever had any Subsidiaries. The Company has not (nor has had) any interest in any entity that is disregarded as separate from the Company for Tax purposes. The Company is not subject to any joint venture, partnership, or limited liability company or other arrangement or Contract that is or should be treated as a partnership for federal income tax purposes (except such agreements as relate to the Company’s status as a partnership for U.S. federal income Tax purposes). The Company is not a successor to any other Person by way of merger, liquidation, reorganization or similar transaction.

(k) Listed Transactions. The Company has not been a party to or participated in, nor are any of the currently a party to or participating in, a “listed transaction” or a “reportable transaction” within the meaning of Section 6707A(c)(2) of the Code and Treasury Regulation Section 1.6011-4(b)(2) or any transaction requiring disclosure under a corresponding or similar provision of state, local, or foreign Law.

(l) Tax Classification. The Company is and has been at all time since its inception treated as a “partnership” for U.S. federal income Tax purposes and for the purposes of any applicable local, state or foreign Tax Law and neither the Company, nor any Unitholder nor any Governmental Authority has taken a position inconsistent with such treatment. The Company has not made an election pursuant Treasury Regulations Section 301.7701-3 (or any comparable provision pursuant to state, local or foreign Law) to be treated as an association for Tax purposes and the Company has never been so treated.

(m) In the event that the Closing hereunder and the Syntroleum Closing do not happen on the same date, except as set forth in the Seller Disclosure Schedules, Seller further hereby represents and warrants to Purchaser and Parent as follows:

(i) The Company shall make and file a valid election under Section 754 of the Code on the tax return filed for the period ended on the date of the Syntroleum Closing;

(ii) None of the assets of the Company are section 197 intangibles (as defined in Section 197 of the Code) which were (i) held or used as any time on or after July 25, 1991, and on or before August 10, 1993 by the Company or a related taxpayer (as determined pursuant to Section 197(f)(9)(C) of the Code), or (ii) acquired from a person who held such intangible at any time on or after July 25, 1991, and on or before August 10, 1993. The Company has not granted the right to use any section 197 intangible to any person (or a person related to such person) who held or used the intangible on or after July 25, 1991, and on or before August 10, 1993; and

(iii) None of the assets of the Company constitute contributed property subject to Section 704(c) or Section 737 of the Code.

Such Tax Returns shall be prepared (i) in a manner consistent with comparable Tax Returns (including amended Tax Returns) of the Company filed for the most recent prior fiscal period for which such Tax Returns were filed unless otherwise required by Law or except for any positions that do not satisfy the “more likely than not” standard (it being understood that all positions in such Tax Returns shall satisfy such standard). Such Tax Returns shall be delivered to Purchaser, and Seller will make available to Purchaser copies of any workpapers relating to such Tax Returns and other information and documentation necessary for Purchaser to review and understand such Tax Returns, not less than thirty (30) days prior to their required filing date, and Seller shall not file any such Tax Returns. Prior to the filing of any such Tax Returns, Seller shall, and shall cause its Affiliates and its and their officers, employees, agents and representatives to, provide to Purchaser all additional information, records, documents and assistance reasonably requested by Purchaser to assist Purchaser in such review and understanding. Purchaser shall notify Seller of any objection to any items set forth on such draft Seller Tax Returns and Seller shall make any changes to such Seller Tax Returns reasonably requested by Purchaser, it being understood that all reporting positions on such Seller Tax Returns should satisfy at least a “more likely than not” standard as defined in Treas. Reg. Section 1.6662-4(d)2 (it being understood that such standard shall be applied whether or not the underlying Seller Tax Return is an Income Tax Return). Purchaser and Seller shall attempt in good faith to resolve before the due date for filing any disagreements as to the proper method for reporting any items on the Seller Tax Returns. Any such disputes between Purchaser and Seller that cannot be resolved by Purchaser and Seller within fifteen (15) days after receipt by Seller of the notice referred to above shall be referred thereafter for decision at the insistence of either Purchaser or Seller to a Referee (who shall either be independent nationally recognized tax counsel or an independent nationally recognized accounting firm) the cost of which will be split equally between Seller and Purchaser. The parties shall furnish to the Referee such information and documents as the Referee may reasonably request in order for the Referee to resolve such dispute. The Referee shall only consider those items in the Seller Tax Returns that Purchaser and Sellers are unable to resolve or are reasonably dependent upon or affected by the unresolved items. The Referee shall reach a conclusion as to whether Seller’s proposed position meets the “more likely than not” standard and shall deliver a written notice of the Referee’s conclusion to Purchaser and Seller within thirty (30) days after such matter is referred to the Referee. The Referee’s conclusion shall be final and binding on and shall not be appealable by the parties hereto absent manifest error such that if Seller’s position meets the “more likely than not” standard the Seller Tax Returns will be filed based upon that position and if it does not meet that standard then they will not be filed in that manner. To the extent practical, Seller or the Company shall delay the filing of a disputed Seller Tax Return pending the conclusion of the Referee, provided that in no event will Seller or the Company be required to delay filing any such Seller Tax Return past the date that is five (5) days before the final due date for such Seller Tax Return. If the Referee has reached a conclusion prior to the time that a Seller Tax Return must be filed then (i) in the case of a Seller Income Tax Return, the filing position shall reflect Seller’s position and (ii) in the case of a Seller Other Tax Return, the filing position shall reflect Purchaser’s position. If the Referee reaches a conclusion that the position taken on a Seller Tax Return filed pursuant to the immediately preceding sentence does not meet the “more likely than not” standard, then the party whose position is upheld by the Referee may, in its absolute discretion, require an amended Tax Return be filed to reflect such prevailing party’s position.

(b) The Company shall prepare or cause to be prepared and file or cause to be filed any Tax Returns of the Company for any period ending on or prior to the Closing Date (except to the extent such Tax Returns are prepared by the Seller pursuant to Section 6.6(a)). Such Tax Returns shall be subject to Seller’s right to review any such Tax Returns within not less than thirty (30) days prior to their required filing date (including applicable extensions) and Purchaser shall not unreasonably refuse to reflect any timely comments of the Representative with respect to such Tax Returns. Seller shall timely remit (or cause to be timely remitted) to the Company (i) with respect to Tax Returns for any period ending on or prior to the Closing, any Taxes shown due on such Tax Returns; and (ii) with respect to any Tax Returns for any Straddle Period, the amount of Taxes allocable to the portion of the Straddle Period ending on the Closing Date (as determined pursuant to Section 6.6(c)), all in accordance with Seller’s membership interest in the Company during the relevant period covered by such Tax Returns (it being understood that Seller’s membership interest during such period is generally fifty percent (50%).

(c) In the case of any Straddle Period, the amount of Taxes allocable to the portion of the Straddle Period ending on the Closing Date shall be deemed to be (i) in the case of Taxes imposed on a periodic basis (such as real or personal property Taxes), the amount of such Taxes for the entire period multiplied by a fraction, the numerator of which is the number of calendar days in the Straddle Period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire relevant Straddle Period and (ii) in the case of Taxes not described in clause (i) (such as Taxes that are based upon or related to income or receipts, based upon occupancy or imposed in connection with any sale or other transfer or assignment or property (real or personal, tangible or intangible)), the amount of any such Taxes shall be determined as if such taxable period ended as of the close of business on the Closing Date.

(d) Notwithstanding anything in Article IX to the contrary, following the Closing, Purchaser shall control all Proceedings (including any audits or administrative or judicial proceedings) relating to Taxes of the Company, except as otherwise provided in this Section 6.6(d). In the case of an audit or administrative or judicial proceeding that relates to the federal and state partnership income tax returns of the Company for periods ending on or prior to the Closing Date, Seller shall have the right, at the expense of the Seller, to control the conduct of such Proceeding, and Purchaser shall have the right, at its expense, to participate in such Proceeding. If the Seller chooses not to control such Proceeding, the Purchaser shall have the right, at the expense of Seller (which expenses shall be reasonable), to control such Proceeding. The party controlling a Proceeding for a Pre-Closing Tax Period that could reasonably give rise to an indemnification obligation pursuant to Article IX shall in any event keep the other party informed of the progress of such Proceeding, shall promptly provide the other party with copies of all material documents (including material notices, protests, briefs, written rulings and determinations and correspondence) pertaining to such Proceeding and shall not settle such Proceeding without the other party’s advance written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

(e) After the Closing Date, to the extent reasonable, Purchaser and Seller shall (and shall cause their respective Affiliates to) (i) assist the other party in preparing any Tax Returns which such other party is responsible for preparing and filing in accordance with Section 6.6 (a) and (b), (ii) cooperate fully in preparing for and conducting any audits of, or disputes with Taxing Authorities regarding, any Tax Returns of the Company, and (iii) make available to the other party and to any Taxing Authority as reasonably requested all information, records, and documents relating to Taxes of the Company for any Pre-Closing Tax Period or any Straddle Period. In addition, Seller shall (and shall cause its Affiliates to) cooperate with Purchaser in connection with preparing any document required for financial accounting purposes or in connection with any regulatory requirement to the extent it involves any Tax matter of the Company or its Affiliates for or related to any Pre-Closing Period (including any Taxes related to any transaction or operation occurring during such period). In furtherance of any of the foregoing, Purchaser and Seller shall retain (and shall cause their Affiliates to retain) copies of all Tax Returns and related papers for all taxable periods that include the Closing Date and all prior taxable periods until the later of (a) the expiration of the statute of limitations to which such Tax Returns relate or (b) six (6) years following the due date (without extension) for such Tax Returns and cooperate in the preparation of any Tax Returns required to be filed by or with respect to the Company, including making available all information, records and documents reasonably requested for purposes of preparing Tax Returns, financial accounting records, or any document required to be prepared in connection with any regulatory requirement. Seller and Purchaser shall provide timely notice to each other in writing of any pending or threatened Tax audits, assessments or Actions with respect to the Company for any Taxable period for which the other party may have Liability under this Agreement.

(f) On or prior to the Closing but in no event later than the date such information is reasonably required by the Purchaser, Seller shall provide Purchaser with a schedule setting forth a list describing all Tax Returns of the Company or reflecting operations of the Company to the extent that such Tax Return is required to be filed (A) for any Tax period ending before the Closing Date (if such Tax Return has not been filed by the Closing Date); (B) for any Tax period ending on the Closing Date; and (C) for any Straddle Period. Such schedule shall include the due date of such Tax Return (including whether any relevant extension has been files) and the party responsible for filing such Tax Return. Within a reasonable time following the Closing but in no event later than the earlier of (i) the date such information is reasonably required by the Purchaser and (ii) 60 days after the Closing Date, Seller shall provide Purchaser with a description of any tax holidays or incentives that are or have been available to the Company. Seller shall also provide the Purchaser (and after the Closing, the Company) with material and relevant information, as and to the extent reasonably requested by the Purchaser and the Company, in connection with compliance with FIN 48 for periods subsequent to Closing.

(g) If the Closing and Syntroleum Closing occur on the same day, the parties acknowledge that the purchase and sale of the Interest shall be treated for U.S. federal income Tax purposes according to the principles illustrated in Situation 2 of Rev. ▇▇▇. ▇▇-▇, ▇▇▇▇-▇ ▇.▇. 432 to the extent allowed by Law. Pursuant to such treatment, the partnership will terminate for federal and state income Tax purposes on the Closing Date and Seller shall file a final partnership return for federal and state income Taxes for the taxable year ending on the Closing Date.

***

(h) Purchaser shall allocate the applicable portions of the Closing Purchase Price paid to Seller plus the value of any Indebtedness assumed or paid by Purchaser, including, without limitation, the Tyson Note, plus any other relevant items among the assets of the Company, consistent with the principles of Situation 2 of Rev. Rul. 99-6, 1999-1 C.B. 432 (or such other relevant federal income tax principles as may be applicable, such as Situation 1 of Rev. Rul. 99-6 in the event that the Syntroleum Closing occurs prior to the day of the Closing). Purchaser shall prepare a draft schedule documenting such allocation and shall provide such draft schedule to Seller no more than sixty (60) days after Closing. Seller shall be entitled to review and comment on such schedule for ten (10) Business Days, and Seller and Purchaser shall negotiate in good faith with respect to any disagreement on the allocation set forth on such schedule. Neither Purchaser nor Seller shall take any position (whether in audits, Tax Returns or otherwise for Tax purposes) that is inconsistent with such finally agreed upon allocation, unless otherwise required by Law.

(i) The parties shall treat any indemnity payments made pursuant to Article IX as adjustments to the Purchase Price for Tax purposes unless applicable Tax Law causes such payment not to be so treated.

(j) To the extent relating to the Company, Seller shall terminate (or cause to be terminated) on or before the Closing Date all Tax Sharing Agreements (other than this Agreement), if any, to which the Company, on the one hand, and Seller or any Affiliate of Seller, on the other hand, are parties, and neither Seller nor any its Affiliates, on the one hand, or the Company, on the other hand, shall have any rights or obligations thereunder after the Closing.

(k) To the extent permitted by Law, Seller and Purchaser shall take all actions necessary in all relevant taxing jurisdictions to effect a closing of the Tax year on the Closing Date.

(l) In the event that the Closing and the Syntroleum Closing do not happen on the same date, Seller shall cause the Company to have in effect for its taxable year which includes the Closing an election under Section 754 of the Code and shall take no action that would revoke, terminate or otherwise adversely affect the validity of such election.

(m) Except for relevant representations of Seller in Article IV, neither Seller, Parent or Purchaser makes any representations or warranties to the other (including its Subsidiaries) or to any holder or any former holder of any of Seller’s or Parent’s equity securities regarding the Tax treatment of the Contemplated Transactions.

6.7 Non-competition.

(a) For a period of *** (***) months commencing on the Closing Date (the “Restricted Period”), Seller shall not (i) directly, indirectly or constructively own or operate a business engaged in the production of any *** (the “Restricted Business”) in any *** (the “Area”); or (ii) have an interest (i.e., as a partner, shareholder, member, lender, joint venture partner, director, manager, employee, principal, agent or trustee) in any Person that engages directly or indirectly in the Restricted Business in the Area. Further, Seller agrees that it will not intentionally and knowingly interfere in any material

***

respect with the business relationships (whether formed prior to or after the date of this Agreement) between the Company and customers or suppliers of the Company during the Restricted Period.

(b) For a period of *** months commencing on the Closing Date, Seller shall not (i) agree, orally or in writing, to acquire any direct, indirect, or constructive ownership or other interest in a Restricted Business in the Area, or (ii) enter into any agreement, oral or written, giving Seller a direct, indirect or constructive ownership or other interest in a facility under construction or to be constructed in the future that, when operational would constitute a Restricted Business in the Area. In the event Seller enters into any agreement contemplated by the proceeding sentence following the six (6) month period after the Closing Date, Seller agrees that it will not make any public announcement or statement regarding such agreement and will use its commercially reasonable efforts to ensure its counterparties do not make any public announcement or statement regarding such agreement, for a period of *** from the Closing Date. In the event a counterparty makes an announcement or statement during such *** period, Seller will forbid such counterparty from naming Seller in such public announcement or statement. Notwithstanding this Section 6.7, Seller and such counterparties are not be prohibited from making any announcement or statement required under applicable securities laws or the rules of any securities exchange during such *** period.

(c) Notwithstanding the terms of the foregoing subsections (a) and (b), nothing contained herein shall prohibit or restrict Seller or any of its respective Affiliates from directly or indirectly (i) engaging in the sale of fats, oils or grease feedstocks to biodiesel or renewable diesel production facilities, including sales on formula pricing that could include profitability from processing the feedstocks so long as Seller has no involvement in the operation of the Restricted Business and there are no public announcements during the Restricted Period of such transactions unless required by Law, (ii) acquiring entities or businesses that own biodiesel or renewable diesel production facilities so long as such biodiesel or renewable fuel production facilities represent less than twenty percent (20%) of the consolidated revenue during the most recently completed fiscal year of such acquired entity or business and less than twenty percent (20%) of the value of such entity or business, or (iii) owning, directly or indirectly, solely as an investment, securities of any Person traded on any national securities exchange if Seller is not a controlling Person of, or a member of a group which controls, such Person and does not, directly or indirectly, own five percent (5%) or more of any class of securities of such Person.

(d) Seller acknowledges and agrees that (a) irreparable damage would likely occur in the event that any of the provisions of this Section 6.7 were not performed in accordance with the specific terms hereof or were otherwise breached, and (b) Purchaser will be entitled to seek specific performance of the terms hereof in addition to any other remedy to which it is entitled at law or in equity. Accordingly, Purchaser shall be entitled to an injunction or injunctions, without the posting of any bond, to prevent breaches of this Section 6.7 by the Seller and to enforce specifically the terms and provisions of this Section 6.7.

(e) Seller acknowledges that the restrictions contained in this Section 6.7 are reasonable and necessary to protect the legitimate interests of Purchaser and constitute a material inducement to Purchaser to enter into this Agreement and consummate the Contemplated Transactions. In the event that any covenant contained in this Section 6.7 should ever be

adjudicated to exceed the time, geographic, product or service, or other limitations permitted by applicable Law in any jurisdiction, then any court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service, or other limitations permitted by applicable Law. Seller agrees that Purchaser and Parent, in addition to any other remedies available to it, will be entitled to preliminary and permanent injunctive relief against any Breach by Seller of any of the covenants contained in this Section 6.7, without the necessity of showing actual monetary damages or the posting of a bond or other security. The covenants contained in this Section 6.7 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.

6.8 Company Operating Agreement.

(a) Prior to or concurrently with the Syntroleum Closing, Seller agrees to take any and all actions reasonably requested by Purchaser or the Company to admit Purchaser as a member of the Company under Section 9.5(b) of the Company Operating Agreement at the time of the Syntroleum Closing.

(b) The Company Operating Agreement is amended, effective as of the Syntroleum Closing, to replace all references to “Syntroleum” with a reference to Purchaser. In addition, Seller waives and relinquishes any claim that Purchaser violates or will violate Article V of the Company Operating Agreement by virtue of (i) the currently existing business of producing and selling biodiesel and related activities by Affiliates of Purchaser or (ii) the future pursuit by Affiliates of Purchaser of business opportunities that are substantially similar to such currently existing biodiesel business. The parties acknowledge that the Company Operating Agreement contains certain terms and conditions in Section 3.5(e) therein with respect to Seller’s rights to receive certain distributions upon a Syntroleum Change of Control (as such term is defined in the Company Operating Agreement) and that such terms and conditions shall remain in full force and effect unless and until the Closing contemplated under Section 1.3 occurs. Upon the Closing, Purchaser will succeed to, among other things, the rights and benefits of Seller for purposes of Section 3.5(e) of the Company Operating Agreement.

(c) Purchaser and Seller agree to negotiate in good faith an amended and restated Company Operating Agreement to become effective at the time of the Syntroleum Closing.

(d) Purchaser and Seller agree to approve (each in its capacity as a member of the Company), and to cause their respective designees to the Management Committee of the Company to approve, the Capital Budget and the Operating Budget attached hereto as Exhibits B and C, respectively, each to be effective as of the Syntroleum Closing.

6.9 Further Assurances. After the Closing, each of the parties, at the reasonable request of any other party, shall execute and deliver such other instruments and do and perform such other acts and things as may be reasonably necessary or desirable for effecting completely the consummation of this Agreement and the Contemplated Transactions.

(b) Neither the Seller nor the Purchaser shall be liable under Section 9.2(a) or 9.3(a), as the case may be, for indemnification of the Purchaser Indemnified Persons or the Seller Indemnified Persons, as the case may be, with respect to any Losses until the aggregate amount

of all such Losses subject to indemnification under Section 9.2(a) or 9.3(a), as the case may be, exceeds $250,000 (the “Threshold”), in which event Seller or Purchaser, as the party responsible for indemnification, shall be required to pay or be liable for all such Losses from the first dollar, except that the party responsible for indemnification shall not be liable for any Losses above the Threshold that do not involve an individual claim or series of related claims that exceeds $5,000.

(c) With respect to any Pre-Closing Taxes of the Company under Section 9.2(c) and any Breach by Seller of any of its representations or warranties regarding the Company contained in Article IV hereof, any Losses suffered or incurred by any Purchaser Indemnified Person and for which indemnification shall be available hereunder shall reflect the fact that Purchaser is only acquiring a 50% interest in the Company pursuant to this Agreement and specifically shall not include Losses suffered or incurred as a result of any other interest in the Company that Purchaser may have or acquire. For example, if the Company sustains or suffers a $100 Loss that is subject to indemnification pursuant to Section 9.2, Purchaser’s Loss and Seller’s responsibility to indemnify Purchaser hereunder, shall be limited to 50% of such Loss, or $50.

(d) The Purchaser Indemnified Persons shall not be entitled to be indemnified for any Losses for Breach of any of Seller’s representations or warranties regarding the Company contained in Article IV hereof (other than with respect to Breach of any representation or warranty contained in Section 4.11(m)) to the extent that the Breach of representation or warranty was directly caused by any action of Purchaser or Parent or their respective Affiliates and was not approved in advance by Seller or its representatives on the Management Committee of Dynamic (it being understood that, prior to the Syntroleum Closing, neither Syntroleum nor the Company shall be deemed an Affiliate of Purchaser or Parent for purposes of this Section 9.4(d)).

(e) Seller shall not be liable for any Losses suffered or sustained by any Purchaser Indemnified Person (other than Losses related to Pre-Closing Taxes) caused by any actions taken by Syntroleum on behalf of the Company between the date of this Agreement and the Syntroleum Closing unless Seller approved the specific action in writing.

(f) In no event shall any party be liable for punitive damages, damages to reputation or loss of good will whether based in contract, tort, strict liability or otherwise; provided, however, that this Section 9.4(f) shall not limit a party’s right to recover any such damages to the extent such party is required to pay damages to a non-Affiliated third party in connection with a matter for which such party is otherwise entitled to indemnification under this Article IX.

(g) The Purchaser Indemnified Persons, on the one hand, and the Seller Indemnified Persons, on the other hand, shall be entitled to recover for a Loss only once under this Article IX even if a claim or claims for indemnification in respect of such Loss has been made as a result of a Breach of more than one representation, warranty, covenant or agreement contained in this Agreement.

(h) In determining the amount of any Losses for which any Purchaser Indemnified Persons or Seller Indemnified Persons are entitled to assert a claim for indemnification hereunder, the amount of any such Losses will be determined after deducting therefrom the amount of any insurance proceeds (after giving effect to any applicable deductible or retention

and resulting retrospective or other premium adjustment) actually received by such Indemnified Persons in respect of such Losses, in each case net of costs and expenses incurred by such Indemnified Persons.

(i) Except with respect to Breaches of Fundamental Representations or resulting from fraud, willful Breach or intentional misrepresentation, the remedies contemplated in Section 6.6 and this Article IX shall constitute the sole and exclusive remedy and recourse, from and after the Closing, of Purchaser, Parent and any Purchaser Indemnified Persons against Seller, and of Seller and any Seller Indemnified Persons against Parent or Purchaser, in connection with Losses arising or resulting from the matters set forth in Section 9.2(a) and 9.3(a). Nothing in this Section 9.4(i) shall limit any Purchaser Indemnified Person’s right to seek and obtain any equitable relief to which any such Purchaser Indemnified Person is entitled pursuant to this Agreement.

(j) Solely for purposes of determining the amount of any Losses for which any Purchaser Indemnified Persons or Seller Indemnified Persons are entitled to indemnification hereunder (and not for purposes of determining whether a Breach has occurred), the representations, warranties, covenants, and agreements of the parties set forth in this Agreement will be considered without regard to any “materiality” or “Material Adverse Effect” qualification set forth in this Agreement.

9.5 Claim Procedure.

(a) If a claim for Losses (a “Claim”) is to be made by any Purchaser Indemnified Person or Seller Indemnified Person (an “indemnified party”) pursuant to Section 9.2 or Section 9.3, respectively, such indemnified party shall give written notice (a “Claim Notice”) to (i) Seller, in the case of indemnification pursuant to Section 9.2, and (ii) Purchaser, in the case of indemnification pursuant to Section 9.3 (the recipient of such notice referred to below as the “indemnifying party”), in either case reasonably promptly after such indemnified party becomes aware of any fact, condition or event which may give rise to Losses for which indemnification may be sought under Section 9.2 or Section 9.3, as the case may be. The Claim Notice shall (i) state that an indemnified party has paid, suffered, incurred, sustained or accrued (or reasonably anticipates that it will have to pay, suffer, incur, sustain or accrue) Losses, and (ii) specify in reasonable detail to the extent available the individual items of Losses included in the amount so stated, the date each such item was paid, suffered, incurred, sustained or accrued, or the basis for such anticipated Loss, and, if applicable, the nature of the misrepresentation, breach of warranty or covenant to which such item is related.

(b) Following its receipt of a Claim Notice, the indemnifying party shall have fifteen (15) calendar days to object to any item(s) or amount(s) set forth therein by delivering written notice thereof, which shall specify in reasonable detail (i) each amount to which the indemnifying party objects and (ii) the nature of each objection (an “Objection Notice”), to the indemnified party submitting such Claim Notice at the address of the indemnifying party set forth herein. In the event that the indemnifying party shall fail to object, pursuant to this Section 9.5(b), to any item or amount set forth in a Claim Notice within the foregoing fifteen (15) calendar day period, the indemnifying party shall be deemed to have irrevocably agreed and consented to indemnify the indemnified party for each such item or amount, subject to Section

9.7 and the other limitations set forth in this Article IX. Any amounts claimed in a Claim Notice and not subject to objection as set forth in the Objection Notice shall be promptly paid or setoff as provided herein.

(c) In the event that the indemnifying party shall object, pursuant to Section 9.5(b) hereof, to any item(s) or amount(s) set forth in any Claim Notice, the indemnifying party and the indemnified party shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the indemnifying party and the indemnified party should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties.

(d) If no such agreement can be reached after good faith negotiation and prior to the date which is thirty (30) calendar days after delivery of an Objection Notice, either the indemnifying party or the indemnified party may submit the matter to litigation pursuant to Section 10.6.

9.6 Third Party Claims. In the event that an indemnified party becomes aware of a third party claim (a “Third Party Claim”) which such indemnified party reasonably believes may result in an indemnification claim pursuant to this Article IX, such indemnified party shall notify the indemnifying party of such claim, and the indemnifying party shall be entitled, at its expense, to participate in, but not to determine or conduct the defense of, such Third Party Claim. The indemnifying party shall have the right in its sole discretion to conduct the defense of, and to settle, any such Third Party Claim at its expense if it acknowledges, without qualification, its indemnification obligations hereunder and gives notice of its intention to do so to the indemnified party within thirty (30) days of the receipt of such notice from the indemnified party; provided, however, that the indemnifying party shall not have a right to assume and control the defense if (a) the indemnifying person is not conducting, or does not continue to conduct, the defense of the Third Party Claim in a diligent and reasonable manner, (ii) the Third Party Claim seeks an injunction or other equitable relief that would adversely affect the Company if granted, (iii) the Third Party Claim relates to or arises in connection with any criminal Proceeding or (iv) the indemnified person has been advised by counsel that, based on the defenses and positions expected to be asserted at the time of such advice, a conflict of interest would reasonably be expected to exist between the indemnified person and the indemnifying person in connection with such Third Party Claim. In the event the indemnifying party exercises the right to undertake any such defense against any such Third Party Claims as provided above, the indemnified party will reasonably cooperate with the indemnifying party in such defense and make available to the indemnifying party, at the indemnifying party’s expense, all witnesses, pertinent records, materials and information in the indemnified party’s possession or under the indemnified party’s control relating thereto as is reasonably required by the indemnifying party. Similarly, in the event the indemnified party is, directly or indirectly, conducting the defense against any such Third Party Claim, the indemnifying party will reasonably cooperate with the indemnified party in such defense and make available to the indemnified party, at the indemnifying party’s expense, all such witnesses, records, materials and information in the indemnifying party’s possession or under the indemnifying party’s control relating thereto as is reasonably required by the indemnified party. The indemnifying party will not, without the written consent of the indemnified party (which will not be unreasonably withheld or delayed), settle or compromise any Third Party Claims or consent to the entry of any judgment which does

not include as an unconditional term thereof the delivery by the claimant or plaintiff to the indemnified party of a written release from all liability in respect of such Third Party Claims. No Third Party Claim which is being defended in good faith by the indemnifying party or which is being defended by the indemnified party as provided above will be settled by the indemnified party without the written consent of the indemnifying party (which will not be unreasonably withheld or delayed).

9.7 Earnout. Purchaser may setoff against any Earnout Payment otherwise owing under Section 1.2 hereof any Losses for which it is entitled to indemnification hereunder. Except in the case of Breach of the Fundamental Representations, fraud, willful Breach, or intentional misrepresentation, the parties agree that the sole and exclusive remedy and security for the indemnity provided for in Section 9.2(a) shall be Purchaser’s right of setoff against Earnout Payments otherwise owing to Seller pursuant to Section 1.2 of this Agreement.

9.8 Effect of Investigation. Seller shall not be liable under Section 9.2(a) hereof for any Losses based upon or arising out of any inaccuracy in or Breach of any of the representations or warranties of Seller contained in Article IV of this Agreement if, as of the date hereof, Purchaser or any of its Affiliates or other Representatives has actual knowledge of the specific inaccuracy or Breach. The Purchaser Indemnified Persons’ right to indemnification under Section 9.2(a) shall not be affected by any investigation conducted with respect to, or any knowledge acquired by, Purchaser or any of its Affiliates or other Representatives at any time after the date hereof, with respect to the accuracy or inaccuracy of any representation or warranty contained in Article IV of this Agreement.

9.9 Purchaser’s Intellectual Property Indemnification Obligation. Notwithstanding anything in this Article IX to the contrary, Purchaser agrees to indemnify Seller against Losses related to intellectual property matters to the same extent that Seller is so indemnified by Syntroleum as of the date hereof pursuant to the Site License Agreement, dated June 27, 2012 by and between Syntroleum and the Company, as amended, and the Master License Agreement, dated June 22, 2007, by and between Syntroleum and the Company, as amended.

MISCELLANEOUS

10.1 Amendments. This Agreement may be amended or supplemented only by a writing signed by Purchaser, Parent and Seller, and any amendment or supplement shall be effective only to the extent specifically set forth in that writing.

10.2 Assignment. Except as specifically set forth in this Section 10.2, neither this Agreement nor any right, interest or obligation under this Agreement may be assigned, pledged or otherwise transferred by any of the parties, whether by operation of Law or otherwise, without the prior written consent of Purchaser and Seller; provided that the Company may assign its obligations under Section 1.2 to any other wholly owned subsidiary of Parent in connection with a transfer of the Geismar Facility to such subsidiary. Notwithstanding the preceding sentence, Purchaser and the Company shall have the right to assign their respective obligations under Section 1.2 to a third party in connection with the sale of the Geismar Facility or a majority

interest in the Company, subject to Seller’s prior written consent (which consent shall not be unreasonably withheld). Upon such consented assignment, Purchaser and Parent shall be relieved of all obligations pursuant to Section 1.2. In the event Seller reasonably withholds its consent, such assignment may be consummated; however, Purchaser will remain primarily obligated for the Earnout Payments under Section 1.2 in the event the assignee of such obligations fails to fully perform. If Purchaser sells or transfers its interest in the Company, sells or transfers all or substantially all of the Company’s assets, or completes any other similar transaction or series of related transactions with an unaffiliated third party, and the Company’s obligations in Section 1.2 are not assigned to and assumed by such third party then, Purchaser will pay Seller in cash an amount equal to $35,000,000 less the sum of all previous payments under Section 1.2, any amount set forth in a Claim Notice delivered in good faith that is pending final determination in accordance with Article IX hereof (which will be paid in accordance of the terms of Article IX to the extent resolved in favor of Seller), and all amounts setoff as indemnification of Purchaser pursuant to Section 9.7.

10.3 Counterparts. This Agreement may be executed in any number of counterparts, and by each of the parties on separate counterparts (which may be delivered by facsimile, PDF or other similar electronic transmission), and each of which, when so executed, shall be deemed an original, but all of which shall constitute but one and the same instrument.

10.5 Specific Performance. The parties hereto agree and acknowledge that, in the event of a Breach of any provision of this Agreement, the aggrieved party may be without an adequate remedy at law. The parties therefore agree that in the event of a Breach of any provision of this Agreement the aggrieved party may elect to institute and prosecute proceedings in any court of competent jurisdiction to obtain specific performance or to enjoin the continuing Breach of such provision, as well as to obtain damages for Breach of this Agreement and to obtain reasonable attorneys’ fees.

such federal jurisdiction, the parties consent to be subject to the exclusive jurisdiction of the state courts located in Wilmington, Delaware, and hereby waive the right to assert the lack of personal or subject matter jurisdiction or improper venue in connection with any such suit, action or other proceeding. In furtherance of the foregoing, each of the parties (a) waives the defense of inconvenient forum, (b) agrees not to commence any suit, action or other proceeding arising out of this Agreement or any Contemplated Transactions other than in any such court, and (c) agrees that a final judgment in any such suit, action or other proceeding shall be conclusive and may be enforced in other jurisdictions by suit or judgment or in any other manner provided by Law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY LITIGATION, ACTION, PROCEEDING, CROSS-CLAIM, OR COUNTERCLAIM IN ANY COURT (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF, RELATING TO OR IN CONNECTION WITH (i) THIS AGREEMENT OR THE VALIDITY, PERFORMANCE, INTERPRETATION, COLLECTION OR ENFORCEMENT HEREOF OR (ii) THE ACTIONS OF SUCH PARTY IN THE NEGOTIATION, AUTHORIZATION, EXECUTION, DELIVERY, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

10.7 Disclosure Schedules. The Seller Disclosure Schedules have been arranged in sections corresponding to the relevant sections of this Agreement. No reference to or disclosure of any item or other matter in the Disclosure Schedules shall be construed as an admission or indication that such item or other matter is material (nor shall it establish a standard of materiality for any purpose whatsoever) or that such item or other matter is required to be referred to or disclosed in the Disclosure Schedules.
