(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party by any Person (other than a Party) that are covered by the indemnification under this Article II, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent of the Indemnified Party unless it includes a full release of the Indemnified Party from such claim.

Each Party hereby irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any action or proceeding commenced hereunder or under any other documents contemplated hereby that service of process was in any way invalid or ineffective. The foregoing shall not limit the rights of any Party to serve process in any other manner permitted by applicable law. The foregoing consents to jurisdiction shall not constitute general consents to service of process in the State of New York for any purpose except as provided above and shall not be deemed to confer rights on any Person other than the respective Parties. Each of the Parties hereby waives any right it may have under the laws of any jurisdiction to commence by publication any legal action or proceeding with respect this Agreement. To the fullest extent permitted by applicable law, each of the Parties hereby irrevocably waives the objection which it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement in any of the courts referred to in this Section 4.9 and hereby further irrevocably waives and agrees not to plead or claim that any such court is not a convenient forum for any such suit, action or proceeding.

11

under or in connection with this Agreement or the transactions contemplated hereby or disputes relating hereto. Each Party (a) certifies that no representative, agent or attorney of any other Party has represented, expressly or otherwise, that such other Party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it and the other Parties have been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 4.9.

Exhibit A

In October 2009, the EPA Region 5 issued a Notice and Finding of Violation pursuant to the Clean Air Act (“CAA”) related to the number 1 nitric acid plant at the Operating Company’s facility in East Dubuque, Illinois.
