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.

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).
