SECTION 6.    RINs and Environmental Credits ROFR.

(a)    Party B covenants and agrees that, on and prior to January 15, 2022, it shall not negotiate or enter into any transaction that could constitute a Permitted RINs Transaction or any transaction similar thereto, other than with Party A. From and after the Effective Date, Party A shall have a right of first refusal with respect to any transaction that would constitute a Permitted RINs Transaction proposed to be entered into by Party B with any Person and Party B shall not enter into any Permitted RINs Transaction other than pursuant to this Section 6. Party B shall promptly notify Party A of any proposed bona fide offer to entered into any Permitted RINs Transaction (any such notice an “Offer Notice” and any such offer, a “Third-Party Offer”) which Party B intends to pursue or accept, which notice shall include the proposed counterparty to such transaction, the material terms of such transaction and copies of any proposed term sheets or transactions documents delivered to Party B with respect to such Permitted RINs Transaction. Each such Offer Notice shall constitute an offer made by Party B (a “ROFR Offer”) to enter into an agreement with Party B on the same material terms of such Third-Party Offer.

(b)    At any time prior to the expiration of the thirty day period following Party A’s receipt of the Offer Notice (the "Exercise Period"), Party A may accept the ROFR Offer by delivery to Party B of a written notice of acceptance/binding letter of intent containing the material terms and any standard and customary conditions applicable to the transaction, executed by Party A; provided, however, that Party A is not required to accept any non-financial terms or conditions contained in any ROFR Offer that cannot be fulfilled by Party A as readily as by any other Person (e.g., an agreement conditioned upon the services of a particular individual or the supply of a product exclusively under the control of such third-party offeror).

(c)    If, by the expiration of the Exercise Period, Party A has not accepted the ROFR Offer, and provided that Party B has complied with all of the provisions of this Section 6, at any time following the expiration of the Exercise Period, Party B may consummate the Third-Party Transaction with the counterparty identified in the applicable Offer Notice on material terms that are the same or more favorable to Party B as the material terms set forth in the Offer Notice. For the avoidance of doubt, the terms and conditions of this Section 1 apply to each Third-Party Offer received by Party B on or after the Effective Date.

7.1    Counterparts. This Amendment may be executed in one or more counterparts and by different parties hereto in separate counterparts each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document. However, this Amendment shall bind no party until Party B and Party A have executed and delivered a counterpart. Delivery of an executed counterpart of a signature page to this Amendment by telecopier or other electronic transmission (i.e., a “pdf” or “ tif” document) shall be effective as delivery of a manually executed counterpart of this Amendment.

7.2    Parties in Interest. All of the terms and provisions of this Amendment shall bind and inure to the benefit of the parties hereto and their respective successors and assigns.

7.4    Complete Agreement. This Amendment, the Collateral Agreement, the First Lien ISDA Master Agreement and the other Transaction Documents represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous or oral agreements of the parties.

7.5    Headings. Any Section and paragraph headings used herein are for convenience of reference only, are not part of this Amendment and shall not affect the construction of, or be taken into consideration in interpreting, this Amendment.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be duly executed by their respective authorized officers as of the date and year first above written.
