RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN OF ARMSTRONG WORLD INDUSTRIES, INC. April 11, 2000 By: /s/ Douglas L. Boles ------------------------- Douglas L. Boles Vice-Chairman of the Retirement Committee 3 Independent Auditors' Report ---------------------------- The Retirement Committee Armstrong World Industries, Inc.: We have audited the accompanying statements of net assets available for benefits of the Retirement Savings and Stock Ownership Plan of Armstrong World Industries, Inc. as of September 30, 1999 and 1998 and the related statements of changes in net assets available for benefits for each of the years in the two-year period ended September 30, 1999. These financial statements are the responsibility of the plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Retirement Savings and Stock Ownership Plan of Armstrong World Industries, Inc. as of September 30, 1999 and 1998 and the changes in net assets available for benefits for each of the years in the two-year period ended September 30, 1999, in conformity with generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes as of September 30, 1999 is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Notes to Financial Statements (1) Summary of Significant Accounting Policies ------------------------------------------ (a) Basis of Presentation --------------------- The accompanying financial statements have been prepared on the accrual basis. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from estimates recorded. The financial statements have been prepared in accordance with Statement of Position 99-3, "Accounting for and Reporting of Certain Defined Contribution Plan Investments and Other Disclosure Matters" (SOP 99-3). This standard eliminates the requirement to disclose amounts relating to individual participant-directed investment programs. As required by SOP 99-3, prior year amounts have been reclassified to conform with the current year presentation. (b) Investments in Master Trust --------------------------- The money market portfolio is stated at cost, which approximates fair value. The interest income fund is comprised of guaranteed interest rate contracts within the Master Trust which are fully benefit responsive; and therefore are reflected at contract value plus credited interest in the financial statements. The value of the participant loans represents the unpaid principal of employee loans. The value of all other investments is based on quoted market price. Securities transactions are recognized on the settlement date (the date on which payment for a buy or sell order is made or received), since adjustment to a trade-date basis would not be material. Dividend income is recorded on the ex-dividend date. Realized gains and losses on investments are determined by the average cost method. Employee Stock Ownership Funds ------------------------------ Investments in the Employee Stock Ownership Funds represent shares of Armstrong common stock valued at quoted market price. (c) Expenses -------- All legal, accounting and administrative expenses associated with Plan operations are paid by Armstrong World Industries, Inc. ("Armstrong") (2) Plan Description ---------------- The Retirement Savings and Stock Ownership Plan of Armstrong World Industries, Inc. ("the Plan") is a defined-contribution plan established for the purpose of providing participants a means for long-term savings intended for the accumulation of retirement income in addition to that provided under other retirement plans maintained for the benefit of employees. The Plan is comprised of two parts--Retirement Savings Plan and Employee Stock Ownership Plan (ESOP). Each part has its own set of participant accounts and investment funds. 7 THE RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN OF ARMSTRONG WORLD INDUSTRIES, INC. Notes to Financial Statements, (Continued) (a) Retirement Savings ------------------ Separate balances are maintained for contributions made by or on behalf of a participant. The balances in each fund reflect the participants' contributions together with dividends, interest, other income, and realized and unrealized gains and losses allocated thereon. Each participant may have up to five accounts that make up the participant's total balance: Sheltered account - Participants may contribute from 1% to 15% of ----------------- before-tax compensation as deferred compensation, as permitted under Section 401(k) of the Internal Revenue Code. Standard account - Participants may contribute from 1% to 10% of ---------------- after-tax compensation. Rollover account - Participants may invest any untaxed amounts ---------------- rolled over from another tax-qualified, employer-sponsored plan. Tax-deductible account (MIRA) - This account holds any ----------------------------- contributions made to the Plan before January 1, 1987. No new contributions can be made to this account. Old Match account - This account holds any amount contributed by ----------------- Armstrong before matching contributions were discontinued. No new contributions are being made to this account. Participants have an immediate 100 percent vested interest with respect to their contributions and are fully vested with regard to any previously made matching Armstrong contributions. (b) Stock Ownership --------------- The Stock Ownership portion of the Plan has three accounts maintained for each member for contributions and allocations of shares of Armstrong common stock from the Unallocated Armstrong Common Stock Fund. Participants who elect to reduce their before-tax compensation in amounts ranging from one percent to six percent have these contributions credited to an Exchange Account. Contributions to the Exchange Account are invested in Armstrong common stock. The Plan matches a portion of the contributions made to the Exchange Account with additional shares of Armstrong common stock. The matching amounts are recorded in participants' Match Accounts. The match percentage, either 50% or 75%, is determined by the closing stock price on the last day of the allocation period. For the allocation period ended in December 1997, a 75% fixed match was in place on employee Exchange Account contributions. For the allocation periods ended in June 1998, December 1998 and June 1999 there was a 50% fixed match on employee Exchange Account contributions. Eligible participants also receive shares of Armstrong common stock in their Equity Account. The Equity Account is intended to provide a source of funds to replace certain retiree medical benefits which were phased out in conjunction with the adoption of the ESOP. Participants have an immediate 100 percent vested interest in the full value of their Exchange Account. Interest in the Equity and Match Accounts vest after five years of service. 8 THE RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN OF ARMSTRONG WORLD INDUSTRIES, INC.

Notes to Financial Statements, (Continued) (4) Armstrong Contributions ----------------------- Armstrong is obligated to make semi-annual contributions in cash or Armstrong stock to the Stock Ownership Funds, on June 15 and December 15 of each year, which when aggregated with all exchange contributions, dividends received by the Trustee on the common stock held by the Trust, and trust earnings, is at least equal to the amount necessary to enable the Trustee to pay currently maturing obligations under the Guaranteed ESOP notes. (Note 6) The contribution from Armstrong on December 15, 1999 included 199,053 shares of Armstrong common stock contributed directly to allocated accounts. (5) Employee ESOP Contributions and Dividends ----------------------------------------- Employee ESOP contributions made during the year and dividends paid on Allocated Armstrong Stock are initially deposited into the Fidelity Retirement Money Market Portfolio until the next semi-annual allocation date, at which time they are contributed to the ESOP. During the time in the Fidelity Retirement Money Market Portfolio, these funds earn interest. At September 30, 1999 and 1998, the amounts in the Fidelity Retirement Money Market Portfolio to be contributed to the ESOP were $3,609,424 and $3,530,318, respectively.

Armstrong has guaranteed the payment of principal and interest on the notes.

At September 30, 1999, there were nine loans outstanding totaling $20,551,404. 12 RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN OF ARMSTRONG WORLD INDUSTRIES, INC. Notes to Financial Statements, (Continued) (8) Benefits -------- (a) Retirement Savings Accounts --------------------------- Under terms of the Plan, a participant (or a beneficiary) is eligible for benefits upon retirement, termination of employment, or death before retirement. Disbursement of the total amount credited to a participant's account is payable (i) in a lump sum or (ii) in the case of retirement, in such other manner as requested by the participant and approved by the Plan Administrator. In addition, an active employee may elect to withdraw all or any part of his account attributable to after-tax contributions. Before reaching age 59 1/2, an active employee may withdraw his pretax contributions from the Sheltered Account, provided he can demonstrate financial hardship. Such employee shall be ineligible to make contributions for a 12-month period. An active employee may elect to withdraw all or any portion of his account balance in the Tax-Deductible (MIRA) and Rollover Accounts. Under the rules of the Plan, the participant may borrow up to the lessor of 50% of his balance or $50,000. The money borrowed must come from the Sheltered, Rollover, and Standard Accounts. The amount of the loan is transferred to a Loan Reserve pledged as security for the loan and is evidenced by a promissory note payable to the Plan. Interest rates are determined periodically by the Retirement Committee in accordance with prevailing interest rates. The loans are reflected in the Loan Portfolio investment fund. Loan repayments are made by payroll deductions or in a manner agreed to by the employee and the Plan Administrator. (b) Stock Ownership Accounts ------------------------ Upon death or any other separation from service from Armstrong, participants are entitled to receive a distribution of their vested account balances. Distributions are in the form of a lump sum cash payment or, upon request, Armstrong common stock. (9) Obligation for Benefits ----------------------- All the funds of the Plan are held by investing institutions appointed by Armstrong under a trust agreement or investment contract. Benefits under the Plan are payable only out of these funds. Armstrong has no legal obligation to make any direct payment of benefits accrued under the Plan. Except as may be provided in an investment contract, neither Armstrong nor any investing institution guarantees the funds of the Plan against any loss or depreciation or guarantees the payment of any benefit thereunder. Although Armstrong has not expressed any intent to terminate the Plan, it may do so at any time. In case of termination or partial termination, the total amount in each employee's account will be distributed as the Plan Administrator directs. (10) Eligibility ----------- All regular full-time employees of Armstrong or of any participating affiliated Armstrong are eligible to participate in the Plan except for foreign nationals, leased employees, and those employees in a collective bargaining unit unless the collective bargaining agent for that unit agrees to coverage under the Plan. Eligible participants, who leave Armstrong and are later reemployed, can resume participation in the Plan on the date of rehire. (11) Diversification --------------- Effective January 1, 1997, Plan participants who meet certain age and service requirements were granted the ability to diversify specified portions of their Stock Ownership Account balances in any combination of the other investment funds available for Retirement Savings Account balances, except for the Fidelity Retirement Money Market Portfolio. 13 RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN OF ARMSTRONG WORLD INDUSTRIES, INC. Notes to Financial Statements, (Continued) (12) Federal Income Taxes -------------------- By a letter dated April 21, 1998, the Internal Revenue Service has determined and informed the Armstrong that the Plan qualifies under the applicable provisions of the Internal Revenue Code and is therefore exempt from federal income taxes. (13) Master Trust Agreement ---------------------- Effective October 1, 1990, the Plan established a Master Trust Agreement with Fidelity Management Trust Company. Under the Master Trust Agreement, the Plan assets held by Fidelity Management Trust Company are commingled and invested with the assets of the Retirement Savings and Stock Ownership Plan of Armstrong World Industries, Inc. and the Bonus Retirement Plan of Armstrong World Industries, Inc.
