The parties hereto agree that any breach of the this Agreement shall constitute irreparable harm and entitle any party to obtain immediate injunctive relief to enforce compliance with the terms hereof. The failure of any party to seek or obtain immediate relief shall not constitute a waiver of, and shall not relieve any party from, his or its obligations hereunder. 15. In the event that Tesoro or the Board of Directors of Tesoro shall breach the provisions of paragraphs 4, 5, 6 or 12 of this Agreement, the Solicitation Parties shall be relieved of their obligations pursuant to paragraphs 6 3 and 12 of this Agreement for the balance of the Standstill Period.
