applicable laws, regulations, or accounting principles occurs such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to the Option, then the Committee shall, in good faith and in such manner as it may deem equitable, adjust the financial targets set forth on Appendix A to reflect the projected effect of such transaction(s) or event(s) on Debt Repayment and/or EBITDA, subject to Section 7.1 of the Plan.

The parties hereto acknowledge that this Agreement and the Plan set forth the entire agreement and understanding of the parties and supersede all prior written or oral agreements or understandings with respect to the subject matter hereof.

If any provision of this Agreement shall be invalid or unenforceable, in whole or in part, or as applied to any circumstances, under the laws of any jurisdiction which may govern for such purpose, then such provision shall be deemed, to the extent allowed by the laws of such jurisdiction, to be modified or restricted to the extent and in the manner necessary to render the same valid and enforceable, either generally or as applied to such circumstance, or shall be deemed exercised from this Agreement, as the case may require, and this Agreement shall be construed and enforced to the maximum extent permitted by law, as if such provision had been originally incorporated herein as so modified or restricted, or as if such provision had not been originally incorporated herein, as the case may be.

Section 4.7 Amendment

The Board at any time, and from time to time, may amend the terms of this Agreement, provided, however, that the rights of the Optionee shall not be adversely impaired without the Optionee’s written consent.

Within 20 days of the conclusion of the arbitration hearing, the arbitrator shall prepare written findings of fact and conclusions of law. It is mutually agreed that the written decision of the arbitrator shall be valid, binding, final and non-appealable; provided, however, that the parties hereto agree that the arbitrator shall not be empowered to award punitive damages against any party to such arbitration. To the extent permitted by law, the arbitrator’s fees and expenses will be borne equally by each party. In the event that an action is brought to enforce the provisions of this Agreement or the Plan pursuant to this Section 4.8, each party shall pay its own attorney’s fees and expenses regardless of whether in the opinion of the court or arbitrator deciding such action there is a prevailing party. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL, INCLUDING TRIAL BY JURY, IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THE PLAN OR THIS AGREEMENT.
