Form of Amendment of Restricted Stock Award Agreements between AHI and the
following executive officers: M.D. Lockhart, M.J. Angello, C.A. Engle, S.J.
Senkowski, and W.C. Rodruan.

                            ARMSTRONG HOLDINGS, INC.

                                  AMENDMENT of

                        RESTRICTED STOCK AWARD AGREEMENTS

The Management Development and Compensation Committee of the Board of Directors
of Armstrong Holdings, Inc. (the "Company") has determined that it is necessary
and appropriate to extend the restriction period applicable to all shares of
common stock of the Company remaining subject to restrictions in all
previously-issued Restricted Stock Award Agreements with the executive specified
below (the "Participant").

In addition to and in extension of all currently-remaining restrictions
prescribed in each such Restricted Stock Award Agreement, the restriction period
for all remaining shares covered by such Agreements are hereby extended until
either the Management Development and Compensation Committee or the Board of
Directors of the Company determines that the following conditions have been met:
     1. a Plan of Reorganization has been confirmed by the Court in the chapter
        11 case of Armstrong World Industries, Inc., and
     2. the Company determines that it is appropriate to allow the Participant
        to publicly trade such shares or the proceeds of any distribution to be
        made to or for the benefit of holders of common stock of the Company
        under such Plan.

This extension of restrictions is necessary in view of the current illiquid
nature of Company stock held by the Participant by reason of Company-imposed
constraints on public transactions in Company stock by the Participant relating
to the pending chapter 11 case of Armstrong World Industries, Inc.

This letter constitutes an amendment of each currently-existing Restricted Stock
Award Agreement between the Participant and the Company. Together with said
Agreement(s), this constitutes the complete, binding and conclusive statement of
the terms of agreement between the Company and the Participant relative to all
currently-remaining Restricted Stock in the name of the Participant. All terms
of the Participant's Restricted Stock Award Agreement(s) not modified herein
continue as originally provided.

WITNESS the execution hereof the 22nd day of July, 2002.

ATTEST:                                     ARMSTRONG HOLDINGS, INC.

                            ACCEPTANCE by PARTICIPANT

I agree to the provisions of this Amendment and understand its consequences
relative to my receipt of Company stock free of restrictions under
previously-issued Restricted Stock Award Agreements. Participant accepts the
terms hereof and acknowledges the continuation of restrictions on Restricted
Stock as provided herein.
