SEPARATION AGREEMENT AND RELEASE

This Separation Agreement and Release ("Separation Agreement") is entered into by and between Jeffrey D. Nickel ("Executive" or "you") and Armstrong World Industries, Inc. (the "Company"), and confirms the agreement that has been reached with you in connection with your separation from the Company.

1.Termination of Employment.  The parties acknowledge that as from 11:30 a.m. EDT on April 1, 2011, you are no longer serving as Senior Vice President, General Counsel and Secretary of the Company and you no longer have the duties or authority associated with those offices.  Between the date hereof and the Separation Date (defined immediately below), you agree: (a) to assist with the transition of duties and otherwise be reasonably available to assist on legal matters as needed and directed, provided, however, that (i) you will not report to work at the Company's offices unless expressly authorized by the Company and (ii) nothing in this clause 1(a) alters your "at will" employment status; (b) to continue to be subject to, and bound by, all Company policies and codes of conduct applicable to active employees of the Company; (c) that you no longer have the authority to bind the Company, (d) to not take any action to bind the Company, and (e) to not represent to any third party that you have the authority to bind the Company.  You agree that your separation shall be effective as of June 30, 2011  (the "Separation Date") and as of such date you shall cease to be employed by the Company in any capacity and your separation shall become effective from all positions you then hold with the Company and its subsidiaries.  You further agree to execute promptly upon request by the Company any additional documents necessary to effectuate the provisions of this paragraph 1.

2.Separation Pay and Benefits.  In consideration of your execution of this Separation Agreement and subject to your compliance with your obligations hereunder, including without limitation your obligations under paragraphs 1, 5, 6 and 7, the Company agrees to pay or provide you (subject to the additional terms and conditions set forth in this Separation Agreement) with the benefits described in this paragraph 2.b. through 2.e. and to adhere to the non-disparagement restrictions set forth in paragraph 5.b. below, which exceed any payment and benefits to which you are otherwise entitled.

a.To the extent you remain employed by the Company, the Company shall continue to pay you at your current rate of base salary in accordance with the Company's payroll practices, less applicable withholdings, and you shall continue to participate in the employee benefit plans in which you are currently participating in accordance with, and to the extent permitted by, the terms of such plans.  In addition, the Company shall pay the cost for your executive physical to the extent completed no later than June 30, 2011.

b.The Company shall pay, or cause to be paid, to you a lump sum amount of $311,774.00 (the "Separation Amount"), less applicable withholdings, to be paid within fifteen (15) business days following the Second Release Effective Date (as defined in paragraph 9.d. below).  In the event that the Second Release Effective Date does not occur, such payment shall not be made.

c.If you elect to continue your medical/prescription drug and dental benefits under COBRA, the premiums will be at the active employee rates for the six month period following your Separation Date.  Thereafter, to the extent you are still eligible, the premium will be adjusted to the Company’s full COBRA premium rates.

d.You will be eligible for outplacement services in accordance with existing Company policy based on your current salary grade.

e.The Company shall pay you an additional cash lump sum of $89,000 less applicable withholdings, which shall represent the pro-rata amount of your 2011 bonus under the Management Achievement Plan; to be paid within fifteen (15) business days following the Second Release Effective Date (as defined in paragraph 9.d. below).  In the event that the Second Release Effective Date does not occur, such payment shall not be made.

3.Accrued Benefits.  Whether or not you execute this Separation Agreement, you will be paid for any earned but unused vacation days (which the parties agree shall be $16,980.00), be eligible for professional education expenses, and for unreimbursed business expenses (in accordance with usual Company policies and practices and in no event later than December 31, 2011), to the extent not theretofore paid.  In addition, following the Separation Date, you will be entitled to receive vested amounts payable to you under the Company's 401(k) plan, pension plan and other retirement and deferred compensation plans in accordance with the terms of such plans and applicable law.  Except as specifically set forth herein, your participation in all Company plans (including outstanding stock option awards and performance stock awards) shall remain subject to the terms and conditions of such plans and agreements as in effect from time to time and you agree that such terms and conditions are binding on you and the Company. Schedule A hereto sets forth an inventory of your Company equity awards outstanding as of the date hereof.  Other than as set forth in this Agreement, after the Separation Date, you shall not receive any base salary, annual bonus, long term incentive award, welfare, retirement, perquisite, fringe benefit, or other benefit plan coverage or coverage under any other practice, policy or program as may be in effect from time to time, applying to senior officers or other employees of the Company.

4.No Other Payments or Benefits.  You acknowledge and agree that, other than the payments and benefits expressly set forth in this Agreement, you have received all compensation to which you are entitled from the Company, and you are not entitled to any other payments or benefits from the Company.

5.Nondisparagement.

a.You agree that you will not, with intent to damage, disparage or encourage or induce others to disparage the Company, its subsidiaries, and its current directors and officers and each of their successors and assigns (collectively, the "Company Entities and Persons"); provided that such limitation shall extend to directors and officers only in their capacities as such or in respect of their relationship with the Company and its affiliates.

b.The Company shall instruct all of its directors and officers not to disparage you or induce others to disparage you.

c.Nothing in this Separation Agreement is intended to or shall prevent either party from providing, or limiting testimony in response to a valid subpoena, court order, regulatory request or other judicial, administrative or legal process or otherwise as required by law.  Executive shall notify the Company in writing as promptly as practicable after receiving any request for testimony or information in response to a valid subpoena, court order, regulatory request or other judicial, administrative or legal process or otherwise as required by law, regarding the anticipated testimony or information to be provided and at least ten (10) days prior to providing such testimony or information (or, if such notice is not possible under the circumstances, with as much prior notice as is possible).

6.Cooperation.  Prior to and after the Separation Date, Executive shall reasonably cooperate with the Company, its subsidiaries and affiliates, at any level, and any of their officers, directors, shareholders, or employees: (A) concerning requests for information about the business of the Company or its subsidiaries or affiliates or Executive’s involvement and participation therein, (B) in connection with any investigation or review by any federal, state or local regulatory, quasi-regulatory or self-governing authority (including, without limitation, the Securities and Exchange Commission) as any such investigation or review relates to events or occurrences that transpired while Executive was employed by the Company and (C) with respect to transition and succession matters.  Executive’s cooperation shall include, but not be limited to (taking into account Executive’s obligations to any new employer or entity to which he provides services), being available to meet and speak with officers or employees of the Company and/or the Company’s counsel at reasonable times and locations, executing accurate and truthful documents and taking such other actions as may reasonably be requested by the Company and/or the Company’s counsel to effectuate the foregoing.  Executive shall be entitled to reimbursement, upon receipt by the Company of suitable documentation, for reasonable and necessary travel and other expenses which Executive may incur at the specific request of the Company and as approved by the Company in advance and in accordance with its policies and procedures established from time to time.

7.Confidentiality; Company Property.  You agree that you shall not, without the prior written consent of the Company, disclose to any entity or person any information which is treated as confidential by the Company or any of their subsidiaries or affiliates, and is not generally known or available to the public, including, but not limited to, information protected by the attorney-client privilege or work product doctrine, provided, that you may make disclosures of such confidential information to the extent required by law or legal process, subject to Executive’s obligations under paragraph 5.c..  On or prior to the Separation Date, you shall return to the Company all Company property in your possession or use, including, without limitation, all automobiles, fax machines, printers, cell phones, credit cards, building-access cards and keys, other electronic equipment, and any records, software or other data from your personal computers or laptops which are not themselves Company property, however stored, relating to confidential information, as discussed above; provided that the Executive will continue to have access to his electronic mail account at the Company through the Separation Date.   You recognize that irreparable injury would be caused to the Company, not adequately compensable by money damages, by your violation of the provisions of this paragraph.  You further agree that in the event of any such violation or threatened violation of this confidentiality provision, in addition to such other rights and remedies as may exist in the Company’s favor, the Company will be entitled to recover its attorneys’ fees and costs in any action to enforce any provision of this paragraph, but only in the event the Company is the prevailing party in any such action, and if the Company is not the prevailing party then it shall pay or reimburse you for your attorneys' fees and costs incurred by you in defense of such action.

8.Taxes.  The parties acknowledge and agree that: the form and timing of the Separation Amount and the other  payments and benefits to be provided pursuant to this Agreement are intended to be exempt from or to comply with one or more exceptions to the requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and applicable Treasury Regulations thereunder ("Section 409A").  Notwithstanding any provision of this Separation Agreement to the contrary, to the extent that any payment hereunder would result in the imposition of any individual tax and penalty interest charges imposed under Section 409A of the Code, such payment shall instead be made on the first business day after the date that is six (6) months following your separation from service within the meaning of Section 409A (or death, if earlier).  The Company, its affiliates, subsidiaries, successors, and each of their respective officers, directors, employees and representatives, neither represent nor warrant the tax treatment under any federal, state, local, or foreign laws or regulations thereunder (individually and collectively referred to as the "Tax Laws") of any payment or benefits contemplated by this Separation Agreement including, but not limited to, when and to what extent such payments or benefits may be subject to tax, penalties and interest under the Tax Laws.

9.Release.

a.You agree that, in consideration of the benefits to be provided to you under this Separation Agreement, you hereby waive, release and forever discharge any and all claims and rights which you ever had, now have or may have against the Company and any of its subsidiaries or affiliated companies, and their respective successors and assigns, current and former officers, agents, directors, representatives and employees, various benefits committees, and their respective successors and assigns, heirs, executors and personal and legal representatives, based on any act, event or omission occurring before you execute this Separation Agreement arising out of, during or relating to your employment or services with the Company or the termination of such employment or services, except as provided below.  This waiver and release includes, but is not limited to, any claims which could be asserted now or in the future, under: common law, including, but not limited to, breach of express or implied duties, wrongful termination, defamation, or violation of public policy; any policies, practices, or procedures of the Company; any federal or state statutes or regulations including, but not limited to, Title VII of the Civil Rights Act of 1964, as amended, 42 U.S.C. §2000e et seq., the Civil Rights Act of 1866 and 1871, the Americans With Disabilities Act, 42 U.S.C. §12101 et seq., the Employee Retirement Income Security Act ("ERISA"), 29 U.S.C. §1001 et seq. (excluding those rights relating exclusively to employee pension benefits as governed by ERISA), the Family and Medical Leave Act, §2601 et. seq., any comparable state laws, any contract of employment, express or implied; any provision of the United States or of a state; any provision of any other law, common or statutory, of the United States, or any applicable state.  Notwithstanding the foregoing, nothing contained in this paragraph 9.a. shall (i) subject to paragraph 9.c, impair any rights or potential claims that you may have under the federal Age Discrimination in Employment Act of 1967 (the "ADEA"); (ii) be construed to prohibit Executive from bringing appropriate proceedings to enforce this Separation Agreement; (iii) affect any rights of indemnification, or to be held harmless, or any coverage under directors and officers liability insurance or rights or claims of contribution that you have or (iv) affect any rights as a shareholder of the Company that you have.

b.The Company agrees that, in consideration of your waiver, release and discharge of any and all claims and rights pursuant to paragraph 9.a. and all other consideration provided by you in this Separation Agreement, except as provided below, it shall and shall cause its subsidiaries to waive, release and forever discharge you of any and all claims and rights which the Company and any of its subsidiaries and their respective successors and assigns ever had, now has or may have against you, your heirs, executors, administrators, successors and assigns.  This waiver and release includes, but is not limited to, any claims which could be asserted now or in the future, under: common law, including, but not limited to, breach of express or implied duties, defamation, or violation of public policy; any policies, practices, or procedures of the Company; any federal or state statutes or regulations; any provision of any other law, common or statutory, of the United States, or any applicable state.  Notwithstanding the foregoing, nothing contained in this paragraph 9.b. shall (i) be construed to prohibit the Company from bringing appropriate proceedings to enforce this Separation Agreement or (ii) operate to waive, release or discharge any claims arising out of your fraud or criminal misconduct.

c.By signing this Separation Agreement, the parties represent that they have not and will not in the future commence any action or proceeding arising out of the matters released hereby, and that neither party will seek or be entitled to any award of legal or equitable relief in any such action or proceeding that may be commenced on either parties’ behalf.  The Company has advised you to consult with an attorney of your choosing prior to signing this Separation Agreement.  You represent that you understand and agree that you have the right and have been given the opportunity to review this Separation Agreement and the Second Release (defined below), with an attorney.  You further represent that you understand and agree that the Company is under no obligation to offer this Separation Agreement, and that you are under no obligation to consent to the waiver.

d.In accordance with the additional release contained in Exhibit A hereto (the "Second Release"), you shall have twenty-one (21) days to consider the Second Release and, once you have signed the Second Release, you shall have seven (7) additional days from the date of execution to revoke your consent to the Second Release.  Any such revocation shall be made in writing so as to be received by the Company prior to the eighth (8th) day following your execution of the Second Release, which execution must occur no earlier than the Separation Date and no later than 30 days following the Separation Date.  If no such revocation occurs, the Second Release shall become effective on the eighth (8th) day following your execution, as described above, of the Second Release (the "Second Release Effective Date").

11.No Admission.  This Separation Agreement is not intended, and shall not be construed, as an admission that either you or the Company Entities and Persons have violated any federal, state or local law (statutory or decisional), ordinance or regulation, breached any contract or committed any wrong whatsoever.
