                MANAGEMENT ACHIEVEMENT PLAN FOR KEY EXECUTIVES
                ----------------------------------------------

                                  (PLAN TEXT)
                                  -----------

1.   Purpose
     -------

     The Armstrong World Industries, Inc. (the "Company") Management Achievement
     Plan (the "Plan") is designed to promote the financial success of the
     Company by recognizing the significant contributions individual employees
     can make to the achievement of Company goals. Its objectives are to
     motivate key Company and subsidiary employees to produce outstanding
     results by providing the opportunity to earn financial rewards in relation
     to the attainment of corporate and business unit goals.

     The Plan is based on the concept that the Company establishes for each
     participant at the beginning of the year a target incentive award based on
     the achievement of specific corporate and business unit goals. When the
     year is over, the results actually achieved will be evaluated against these
     goals to determine the amount, if any, of additional compensation earned by
     individuals participating in the Plan.

2.   Administration
     --------------

     The Plan shall be administered by the Management Development and
     Compensation Committee (the "Committee") of the Board of Directors with the
     advice and counsel of the Chief Executive Officer of the Company.
     Designated subsidiary companies may adopt this Plan. Subject to compliance
     with the requirements of Section 162(m) of the Internal Revenue Code for
     deductibility of awards, the Board may amend or terminate the Plan from
     time to time so long as the amendment or termination does not adversely
     affect any rights or obligations with respect to awards for the then
     current year or any prior year which has not yet been paid.

3.   Eligibility
     -----------

     The intent of the Plan is to extend participation only to those key
     employees whose duties and responsibilities give them the opportunity to
     make a continuing material and

     substantial impact on the achievement of organization goals. The Chief
     Executive Officer will annually determine the non-officer participants and
     recommend officer participants to the Committee.

4.   Incentive Awards
     ----------------

     A)  At the beginning of each year, the Chief Executive Officer shall
         present to the Committee criteria for evaluating performance against
         corporate and business unit goals for the purposes of determining the
         incentive awards which shall be paid for the year.

     B)  At the same time, the Chief Executive Officer shall recommend to the
         Committee a target award expressed as a percentage of salary for each
         participant.

     C)  As soon as practical following the close of each year, the Chief
         Executive Officer shall evaluate the levels of corporate and business
         unit achievement and recommend to the Committee the incentive amount
         earned by the participants.

     D)  Absent specific Board authorization to the contrary, no awards under
         the corporate achievement segment of the Plan shall be authorized as to
         any year in which the consolidated Company results fail to achieve a
         minimum return on stockholders' equity of 8.5%.
