9.                                      Non-Disparagement.  Each of Purchasers and the Company shall not, and shall cause their respective controlled Affiliates not to, and shall instruct and use their reasonable best efforts to cause their respective directors, officers, employees, advisors and representatives not to, make (or authorize the making of) any statement publicly for a period of two (2) years from the date hereof about this Agreement, any of the Transaction Documents, the Apollo Agreements or the Transactions or about the Purchasers or the Company or its or their respective Affiliates that denigrates or disparages the Company or the Company Releasees (in the case of Purchasers) or Purchasers or the Purchasers Releasees (in the case of the Company), including without limitation, any statement that is critical of the Company or the Purchasers or their respective Affiliates, as applicable, or (in the case of the Purchasers only) that expresses a view regarding the financial position of the Company or its future prospects (a “Prohibited Statement”), provided, however, that for the avoidance of doubt the foregoing shall not be deemed to prevent or impair any person covered thereby from testifying in any legal or administrative proceeding, responding to inquiries or requests for information by any regulator or auditor, or taking any other action that is, in the opinion of legal counsel for a Party, required by law, or to prevent the Parties from making statements in any pleadings, court papers or in open court in any action brought by one of the Parties in connection with a breach of this Agreement or the promissory notes or in any action brought by any other person relating to this Agreement, the Purchase Agreement, the Original Agreement, the Investors Rights Agreement, the Royalty Agreement, the Apollo Agreements or the Transactions.  As used in this Section 9, a statement is made “publicly” if it is made to a person who is not a officer, director, employee, advisor or representative of the Company or the Purchasers or its or their respective Affiliates, except that statements made to members of the immediate family (as defined in the Corporate Governance rules of the New York Stock Exchange as in effect on the date of this Agreement) shall not be deemed to be made publicly.  If during the two (2) years after the date hereof a Party or one of its current or future directors, officers and employees makes a Prohibited Statement, then another Party may notify that Party of its objection to the statement, providing reasonable detail regarding such statement.  Promptly following receipt of such notice, the Party receiving the notice shall attempt to confirm the facts surrounding the alleged Prohibited Statement, and if in its good faith opinion the contents of the notice are accurate, then the Party receiving the notice shall promptly make an appropriate public retraction or correction. Each of the Parties agrees that the rights and remedies for noncompliance with this Section 9 shall include having such provisions specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to the non-breaching Party and that money damages would not provide an adequate remedy to such Party.

11.                               Consulting Reports. Subject to any required consent from any third parties, each Purchaser hereby assigns all of its right, title and interest in and to all reports, presentations or other work product related to the Company or its Subsidiaries prepared by McKinsey & Company, SRK Consulting or any other similar consulting or technical advisory firm (excluding, for the avoidance of doubt, any reports, presentations or other work product from legal advisors) (collectively, the “Consulting Reports”) to the Company, provided, that the Purchasers shall be entitled to retain copies of such Consulting Reports for legal and compliance purposes or to comply with any bona fide records retention policy. Each Party hereby agrees that it shall use commercially reasonable efforts to, whenever and as often as reasonably requested to do so by the other or the other’s successors and assigns (but in no event later than three months from the date hereof), and without further consideration, execute, acknowledge and deliver such further instruments of transfer, assignment, consents, conveyance, assumption and delivery, and take such other actions as reasonably may be necessary in order to effectuate the transfer of the Consulting Reports to the

4

Company; provided, however, that, for the avoidance of doubt, in no event shall the Purchasers or any of their Affiliates be required to make any payments or incur any liabilities or obligations in connection with such efforts to transfer or assign such Consulting Reports.  From and after the effectiveness of any such transfer or assignment, the Company agrees to comply with the terms of any engagement letter with any such consulting or advisory firm applicable to the ownership of such Consulting Reports.

12.                               Indemnification.  The Company hereby agrees to indemnify Purchasers and their Affiliates and their respective directors, trustees, officers, employees, partners, members, attorneys and agents (collectively, “Indemnified Party”) from, and hold each of them harmless against, any and all losses, liabilities, claims, damages or expenses (collectively, “Losses”) incurred by any of them arising out of or by reason of any investigation or litigation or other proceedings (including any threatened investigation or litigation or other proceedings) commenced or threatened by any person (including the Company or its shareholders but excluding any Indemnified Party and any Affiliate of or investor in an Indemnified Party (except to the extent such person who is not a Purchaser or an Affiliate of the Purchaser is a direct or indirect shareholder in the Company and acted in such capacity in connection with any such investigations, litigations or other proceedings)) relating to this Agreement, the Transaction Documents, the promissory notes or the transactions related hereto or thereto, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation or litigation or other proceedings; provided, however, in no event shall any such indemnification obligation apply to any breach by the Purchasers of the provisions of this Agreement. Notwithstanding anything to the contrary in this Agreement, the Company is not obligated to indemnify or defend Indemnified Party against any third-party claim if such third-party claim or corresponding Losses arise out of or result from, in whole or in part, Indemnified Party’s (i) gross negligence or more culpable act or omission (including recklessness or willful misconduct), or (ii) bad faith failure to comply with any of its obligations set forth in this Agreement, the Transaction Documents, the promissory notes or the transactions related hereto or thereto.

13.                               Litigation.

(a)                                 Each of the Parties submits to the jurisdiction of any federal court sitting in the Southern District of New York  (or, to the extent that subject matter or personal jurisdiction does not exist in any such federal court, then in any New York state court sitting in the Borough of Manhattan in New York, New York; together with such federal courts, the “New York Courts”) in any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of, or in connection with, this Agreement or the transactions contemplated hereby and hereby irrevocably waives the benefit of jurisdiction derived from present or future domicile or otherwise in such action or proceeding.  Each Party hereto irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.  Each Party agrees not to assert, by way of motion, as a defense or otherwise, in any action or proceeding in which such a claim is asserted, that it is not subject personally to the jurisdiction of the New York Courts, that the claim is brought in an inconvenient forum, that the venue of the action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by the New York Courts.  Each Party further irrevocably submits to the jurisdiction of the New York Courts with respect to any such action or proceeding.

(b)                                 Service of process shall be effective against any Party if delivered personally, by facsimile (with confirmation), mailed by registered or certified mail (return receipt requested), or delivered by an express courier (with confirmation) to such Party as follows:
