Definitions

As used in this Agreement, all capitalized terms not otherwise defined herein shall have the respective meanings set forth in the First Amended and Restated Agreement of Limited Partnership of Sprague Resources LP dated as of October 30, 2013.

ARTICLE II

Right of First Refusal

Axel Johnson hereby agrees, and will cause its controlled Affiliates to agree, for so long as Axel Johnson or its controlled Affiliates, individually or as part of a group, control the General Partner, that if Axel Johnson or any of its controlled Affiliates has the opportunity to acquire a controlling interest in any assets or any business having assets that are primarily engaged in the businesses in which the Partnership is engaged as of the closing of the Initial Offering and that operate primarily in the United States or Quebec, Ontario or the Maritimes, Canada, then Axel Johnson or its controlled Affiliates will offer such acquisition opportunity to the Partnership and give the Partnership a reasonable opportunity to acquire such assets or business either before Axel Johnson or its controlled Affiliates acquire it or promptly after the consummation of such acquisition by Axel Johnson or its controlled Affiliates, at a price equal to the purchase price paid or to be paid by Axel Johnson or its controlled Affiliates plus any related transactions costs and expenses incurred by Axel Johnson or its controlled Affiliates. The Partnership’s decision to acquire or not acquire any such assets or businesses will require the approval of the Conflicts Committee. Any assets or businesses that the Partnership does not acquire pursuant to this right of first refusal may be acquired and operated by Axel Johnson or its controlled Affiliates.

This right of first refusal will not apply to:

ARTICLE III

Right of Negotiation

Axel Johnson hereby agrees and will cause its controlled Affiliates to agree, for so long as Axel Johnson or its controlled Affiliates, individually or as part of a group, control the General Partner, that if Axel Johnson or any of its controlled Affiliates decide to attempt to sell (other than to another controlled Affiliate of Axel Johnson) any assets or businesses that are primarily engaged in a business in which the Partnership is engaged as of the closing of the Initial Offering and that operate primarily in the United States or Quebec, Ontario or the Maritimes, Canada (including its equity interests in 9047-1137 Quebec, Inc. or any successor entities (“Kildair”) and its interests in any assets or equity interests in any business that, as of the Closing Date, it is actively seeking to invest in or acquire or has the right to invest in or acquire), Axel Johnson or its controlled Affiliate will notify the Partnership of its desire to sell such assets or businesses and, prior to selling such assets or businesses to a third party, will negotiate with the Partnership exclusively and in good faith for a period of 60 days in order to give the Partnership an opportunity to enter into definitive documentation for the purchase and sale of such assets or businesses on terms that are mutually acceptable to Axel Johnson or its controlled Affiliate and the Partnership. If the Partnership and Axel Johnson or its controlled Affiliate have not entered into a letter of intent or a definitive purchase and sale agreement with respect to such assets or businesses within such 60 days, Axel Johnson or its controlled Affiliate will have the right to sell such assets or businesses to a third party following the expiration of such 60 days on any terms that are acceptable to Axel Johnson or its controlled Affiliate and such third party. The Partnership’s decision to acquire or not to acquire assets or businesses pursuant to this right will require the approval of the Conflicts Committee. The Partnership’s right of negotiation contained in this Article III, to the extent it applies to any of Axel Johnson’s direct or indirect equity interests in Kildair, any subsidiary of Kildair, or any entity that owns equity interests in Kildair shall not be applicable to any transfer, assignment, foreclosure, deed-in-lieu of foreclosure, or other disposition of any such equity interests occurring as a result of the exercise of remedies by any lenders to Kildair, any subsidiary of Kildair, or any entity that owns equity interests in Kildair.
