WHEREAS, pursuant to the Merger Agreement, Sunoco has the right, but not the obligation, to cause a wholly owned Subsidiary of Sunoco that is treated as a corporation or a partnership for U.S. federal income tax purposes, to subscribe, immediately prior to and conditioned on the occurrence of the Effective Time, for a number of common units representing limited partner interests in NuStar and having the rights and obligations specified with respect to “Common Units” in the Existing Partnership Agreement (the “Units”) representing one percent of all Units outstanding immediately following such issuance at a price per Unit equal to the closing price of one Unit reported on the NYSE on the full trading day immediately prior to the Effective Time, payable in cash, a note or any other property that Sunoco and NuStar mutually agree to be of equal value;

WHEREAS, Sunoco desires to exercise such right described in the immediately preceding recital and, in furtherance thereof, Sunoco and NuStar desire for NuStar to issue and sell to Sunoco Retail, and Sunoco Retail to purchase from NuStar, 1,278,135 Units (the “Subscribed Units”), subject to the terms and conditions set forth herein.

10. Reserved.

11. Entire Agreement. This Agreement and the Merger Agreement together constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof and thereof, and this Agreement is not intended to grant standing to any person other than the parties hereto.

12. Successor and Assigns; No Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned or delegated by any of the parties hereto without the prior written consent of the other parties.

Notwithstanding the foregoing, no failure or delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

14. Severability. Any term or provision of this Agreement which is held to be invalid or unenforceable in a court of competent jurisdiction shall be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement. Upon such a determination, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the fullest extent possible. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

15. Governing Law. This Agreement, and all claims or causes of action (whether at law, in contract or in tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance hereof, shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

16. Waiver of Jury Trial. EACH OF THE PARTIES HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

This Agreement may be executed in two (2) or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by telecopy, electronic delivery or otherwise) to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.
