Executive acknowledges and agrees that Executive continues to be bound by the restrictive covenants contained in Section 5 of the Change in Control Agreement by and between the Company and Executive, dated as of September 2, 2012. Executive also acknowledges and agrees that Executive continues to be bound by the provisions contained in Sections 13, 16 and 20(d) of the Armstrong World Industries, Inc. 2011 Long-Term Incentive Plan and Sections 13 and 16 of the Armstrong World Industries, Inc. 2006 Long-Term Incentive Plan.

13. Relief. Executive agrees that any breach of the terms of Section 10, 11 or 12 of this Agreement would result in irreparable injury and damage to the Company for which the Company would have no adequate remedy at law; Executive therefore also agrees that in the event of any such breach or any threat of breach, the Company shall be entitled to an immediate injunction and restraining order to prevent such breach, threatened breach or continued breach by Executive and/or any and all persons or entities acting for or with Executive, without having to prove damages, and to all costs and expenses, including reasonable attorneys’ fees and costs, in addition to any other remedies to which the Company may be entitled at law or in equity. In the event of any breach of Section 10, 11 or 12 of this Agreement, all severance payments provided under this Agreement shall immediately cease and be forfeited except for $500, which the parties agree is valid and ongoing consideration for the remainder of this Agreement. The terms of this Section shall not prevent the Company from pursuing any other available remedies for any breach or threatened breach hereof, including but not limited to the recovery of damages from Executive. Executive and the Company further agree that the restrictive covenants referenced in Section 11 are reasonable and that the Company would not have entered into this Agreement but for incorporation by reference of such covenants herein. Should a court determine, however, that any provision of these covenants is unreasonable, either in period of time, geographical area, or otherwise, the parties hereto agree that the covenants should be interpreted and enforced to the maximum extent which such court or arbitrator deems reasonable and the remainder of this Agreement shall remain in full force and effect.

16. Non-Admissions. Nothing in this Agreement shall be regarded as an admission of any wrongdoing, fault, liability, or unlawful activity by Executive, the Company or any Releasee.
