 (a) The Indemnified Party agrees that within a reasonable period of time after it becomes
aware of facts giving rise to a claim for indemnification under this Article II, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim. 

(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. 
 (c) The Indemnified Party agrees to cooperate in good faith and in a
commercially reasonable manner with the Indemnifying Party, with respect to all aspects of the defense of any claims covered by the indemnification under this Article II, including, without limitation, the prompt furnishing to the
Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying
Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense, the making available to the Indemnifying Party of any employees of the Indemnified Party and the granting to
the Indemnifying Party of reasonable access rights to the properties and facilities of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on
the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 2.4. In no event shall the obligation of
the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any
claims covered by the indemnification set forth in this Article II; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying
Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the

registered or certified mail, postage prepaid, to such Party, at its address for notices set forth in this Agreement, such service to become effective ten (10) days after such mailing. 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

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.

 (Omnibus Agreement) 







 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. The notice alleges violations of the CAA’s New Source Performance Standard for nitric acid plants, Prevention of Significant Deterioration
requirements and Title V Permit Program requirements. The notice appears to be part of the Environmental Protection Agency’s Clean Air Act National Enforcement Priority for New Source Review/Prevention of Significant Deterioration related to
acid plants, which seeks to reduce emissions from acid plants through proceedings that result in the installation of new pollution control technology.
