The parties hereto hereby waive all notice of termination requirements and date of termination requirements including those set forth in Sections 7.1 and 7.2 of the Change in Control Agreement between you and the Company dated as of October 27, 2008 (the “Change in Control Agreement”). You further agree to execute promptly upon request by the Company any additional documents necessary to effectuate the provisions of this paragraph 1.

In consideration of your execution of this Separation Agreement and your compliance with its terms and conditions, the Company agrees to pay or provide you (subject to the terms and conditions set forth in this Separation Agreement) with the benefits described in this paragraph 2 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. The benefits below shall be in full satisfaction of the Company’s obligations under the terms of the Change in Control Agreement. The payments specified in paragraphs 2.b., 2.c. and 2.e. shall be paid on the first business day that is at least six months after the Separation Date; provided that such amounts shall be paid within ten days of the date of your death during such six-month period; and provided further that the payments required by this paragraph 2 shall not be made unless the Effective Date (as defined below) has occurred no later than March 31, 2010. The amounts suspended for six months as specified above shall earn interest at the annual rate of 0.72%, compounded monthly.

a. The Company shall continue to pay you at your current rate of base salary through the Separation Date, in accordance with the Company’s payroll practices, less applicable withholdings.

b. The Company shall pay you an aggregate of $7,774,667 (the “Separation Amount”), less applicable withholdings, in full satisfaction of the Company’s obligations under Sections 6.1(A) and (B) of the Change in Control Agreement.

c. The Company shall pay you an aggregate of $3,143,077, less applicable withholdings, in full satisfaction of the Company’s obligations under Section 6.1(C) of the Change in Control Agreement.

3. Accrued Benefits. Whether or not you execute this Separation Agreement, you will be paid for any accrued but unused vacation days (which the parties agree shall be $11,935.90), and for unreimbursed business expenses (in accordance with usual Company policies and practices, and in no event later than December 31, 2010), to the extent not theretofore paid.

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.

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.

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, provided, that you may make disclosures of such confidential information to the extent required by law or legal process.

Exhibit 99.1

Armstrong World Industries Announces Management Change

LANCASTER, PA, February 12, 2010 — Armstrong World Industries, Inc. (“Armstrong”) (NYSE:AWI) announced today that Michael D. Lockhart will be stepping down as the Company’s chief executive and president, and as chairman of the board and a director, effective February 28, 2010. The Board has elected James J. O’Connor, currently the Company’s lead independent director, as chairman. Mr. O’Connor will head a search committee to identify and evaluate candidates for the CEO position. The Board expects to name an interim president in the near future.

The Board of Directors said in a statement:

“Armstrong has accomplished a great deal since Mike became CEO in 2000. Under his leadership, the Company resolved its asbestos liability and emerged successfully from bankruptcy reorganization. The Company’s North American floor business regained its position as an industry leader through enhanced product quality and design, and increased investment in the brand. Thanks to Mike’s prudent management during the sharp economic downturn of the last two years, Armstrong has remained profitable and has grown free cash flow. The Company will reap the benefits of his stewardship. We thank Mike for his important contributions and wish him all the best for the future.”

Mr. Lockhart added, “I have been proud to serve as Armstrong’s CEO for nearly 10 years. I want to thank the thousands of people who have worked together to successfully implement the changes necessary to make this a better company. Armstrong is about to enter a period that has the potential to be the best in its long history. The prospects for the Company are genuinely exciting and I wish my colleagues continued success.”

Mr. O’Connor, incoming chairman of the board, said “The Board and Mike agreed that this was the right time to look for new leadership to take the Company into its next phase of growth. Operationally, the Company is performing well with a strong team of senior leaders, well-known, trusted brands, a solid balance sheet, and dedicated employees. While we continue to expect 2010 to be challenging, we have complete confidence in the Company’s senior management team and their ability to continue to deliver great products and quality service to our customers and distributors around the world.”

Mr. O’Connor has served as a director of the Company since February 2007 and as the lead director since February 2009. He also serves as the lead independent director of the boards of directors of Corning, Inc., Smurfit — Stone Container Corporation, UAL Corporation and United Airlines. He retired as chairman and chief executive officer of Unicom Corporation and its subsidiary, Commonwealth Edison Company, in 1998.

Mr. O’Connor is a past chairman of the board of the Edison Electric Institute and of the Institute of Nuclear Power Operations, and he previously served as a director of Bell and Howell, Borg-Warner, Esmark, Everen Securities, First Chicago Corporation, Tribune Company and Trizec Properties, Inc. He is also active in philanthropic and social justice activities throughout the Chicago area. Mr. O’Connor is a graduate of Holy Cross College, and he has an MBA from Harvard University and a J.D. from Georgetown Law School.
