Item 2.   ACQUISITION OR DISPOSITION OF ASSETS:

          On December 29, 1995, Armstrong World Industries, Inc. (the
"Registrant") sold one hundred percent of the stock in its indirect wholly-owned
subsidiary, American Olean Tile Company, Inc. ("American Olean"), and
contributed $27.6 million in cash, to Dal-Tile International Inc. ("Dal-Tile")
in exchange for 37 percent of Dal-Tile's common stock (the "Business
Combination").  The Business Combination was effected pursuant to a Stock
Purchase Agreement dated as of December 21, 1995, by and among the Registrant
and two of its wholly-owned subsidiaries, on the one hand, and Dal-Tile, on the
other hand.  The Business Combination includes the Registrant's agreement,
suject to regulatory approval, to substitute Dal-Tile for the Registrant's
49.99% interest in Recubrimientos Interceramic, S.A. de C.V. ("RISA"), which is
American Olean's Mexican joint venture partner. American Olean and RISA
manufacture, market and sell ceramic tile and ceramic tile products.

          The consideration received for the shares of American Olean was
determined in arms-length negotiations with Dal-Tile.  The Business Combination
will be accounted for at fair value and the Registrant's 37 percent interest in
Dal-Tile will be accounted for by the equity method.  Dal-Tile is a leading
manufacturer, distributor and marketer of glazed and unglazed tile in North
America.

          Pursuant to a Shareholders Agreement dated December 29, 1995 between
the Registrant and two of its wholly-owned subsidiaries, on the one hand, and
Dal-Tile and AEA Investors, Inc. ("AEA"), on the other hand, the Registrant
initially has the right to designate three of the ten members of the Board of
Directors of Dal-Tile.  The Shareholders Agreement also (i) requires a
supermajority vote of the directors for certain extraordinary actions, and
(ii) sets forth various rights with respect to the Dal-Tile shares owned by AEA 
and by the Registrant, including but not limited to, rights of first refusal, 
take along rights, tag along rights and registration rights. The Registrant is,
however, not aware of any material relationship between it or any of its
directors or officers, or between any affiliate or the directors or officers of
any affiliate, and Dal-Tile that existed prior to the date of the Business
Combination.

          The foregoing is a summary description of the Business Combination and
related transactions and is qualified in its entirety by reference to the Stock
Purchase Agreement and other exhibits filed with this Form 8-K.

          The Registrant issued a press release announcing the consummation of
the Business Combination on January 2, 1996, a copy of which is attached hereto
as Exhibit 99.01.

Item 7.   FINANCIAL STATEMENTS AND EXHIBITS.

to do business as a foreign corporation in each jurisdiction in which the
conduct or nature of its business or the ownership, leasing or holding of its
properties makes such qualification necessary, except such jurisdictions where
the failure to be so qualified or in good standing, individually or in the
aggregate, would not have a material adverse effect on the business, assets,
condition (financial or otherwise), results of operations or prospects of RISA,
or on the ability of AWI and its Subsidiaries to consummate the transactions
contemplated hereby (a "RISA Material Adverse Effect").
                        ----------------------------

          Section 3.30. Subsidiaries and Equity Interests; RISA. Except as set
                        ---------------------------------------

(i) the unaudited balance sheet of RISA as of September 30, 1995 (the "RISA
                                                                       ----
Balance Sheet") and the unaudited statements of income and cash flows of RISA
- -------------
for the six-month period ended June 30, 1995, together with the notes to such
financial statements and (ii) the unaudited balance sheets of RISA as of
December 31, 1994, and the unaudited statements of income and cash flows of RISA
for the year ended December 31, 1994, together with the notes to such financial
statements (the financial statements described above, together with the notes to
such financial statements, collectively, the "RISA Financial Statements"). To
                                              -------------------------

(utilizing only the information provided in such financial statements) by KPMG
Peat Marwick to conform with generally accepted accounting principles in the
United States, in each case, consistently applied (except, in each case, as
described in the notes thereto). Nothing has come to the attention of AWI that
would lead AWI to believe that the RISA Financial Statements (x) do not fairly
present (subject, in the case of the unaudited statements, to normal, recurring
year-end audit adjustments) the financial condition and results of operations of
RISA as of the date thereof and for the period

                                      26

indicated and (y) contain any material misstatement of fact or omit any material
fact necessary to be stated to make the statement therein not misleading.

          (b) Nothing has come to the attention of AWI that would lead AWI to

accrued, absolute, contingent, unasserted, known, unknown or otherwise) in
excess of $250,000 on an individual basis (or with respect to any series of
related liabilities or obligations), except (i) as set forth as a liability in
the RISA Balance Sheet, (ii) for items set forth in Schedule 3.31 or disclosed
in the other Schedules hereto and (iii) for liabilities and obligations incurred
since the date of the RISA Balance Sheet in the ordinary course of business
consistent with past practice and not in violation of any of the terms of this
Agreement.

          Section 3.32. Taxes; RISA. (a) Nothing has come to the attention of
                        -----------
AWI that would lead AWI to believe that (i) any Tax Return required to be filed
and relating to RISA has not been filed in a timely manner taking into account
all extensions of due dates, (ii) any Taxes required to be paid by or with

Taxes for which a notice of assessment or demand for payment has been received
by RISA or any related party, have not been timely and fully paid, (iii) any
Taxes required by law to have been withheld or collected relating to any
business of RISA have not been duly withheld or collected and any Taxes so
withheld or collected and required by law to have been paid over to the
appropriate governmental agency or authority have not been paid over to the
appropriate governmental agency or authority, and (iv) deficiencies for any
Taxes in respect of RISA have been asserted or assessed against RISA or any
related party in writing which remain unpaid.

          (b) Nothing has come to the attention of AWI that would lead AWI to
believe that the reserves for Income Taxes included in the RISA Balance Sheet
with respect to periods or portions of periods ending on or before the date of
the RISA Balance Sheet are not adequate in all respects to cover all liabilities
for Income Taxes with respect to such periods or portions of periods.

          (c) RISA is not a "controlled foreign corporation" within the meaning
of Code Section 957(a).

          Section 3.33. Title to Real Property; RISA. Nothing has come to the
                        ----------------------------
attention of AWI that would lead AWI to believe that RISA does not have (i) good
and insurable fee title to all real property and interests in real property
owned in fee by RISA and (ii) good and valid title to the leasehold estates in
all real property and interests in real property leased by RISA, in each case,
free and clear of Liens other than Permitted Liens.

          Section 3.34. Other Assets; RISA. Nothing has come to the attention of
                        ------------------
AWI which would lead AWI to believe that (i) RISA does not have good and valid
title to all assets reflected on the RISA Balance Sheet or thereafter acquired,
except those sold or otherwise disposed of for fair value since the date of the
RISA Balance Sheet in the ordinary course of business consistent with past
practice and not in violation of this Agreement, in each case free and clear of
all Liens other than Permitted Liens, (ii) that any material tangible personal
property of RISA has not been maintained in all material respects in accordance
with generally accepted industry practice, (iii) that any item of material
tangible personal property of RISA is not, in all material respects, in good
operating condition and repair, ordinary wear and tear excepted and (iv) that
any leased personal property of RISA is not, in all material respects, in the
condition required of such property by the terms of the lease applicable thereto
during the term of the lease and upon the expiration thereof.

          This Section 3.34 does not relate to real property or interests in
real property, such items being the subject of Section 3.33.

          Section 3.35. Intellectual Property; RISA. (a) Nothing has come to the
                        ---------------------------
attention of AWI which would lead AWI to believe (i) that RISA does not own or
have the right to use pursuant to license, sublicense, agreement or permission,
all Intellectual Property used in or necessary for the operation of the business
of RISA as presently conducted and as presently proposed to be conducted (ii)
that any item of Intellectual Property owned or used by RISA immediately prior
to the Closing will not be owned or available for use by RISA on identical terms
and conditions immediately subsequent to the Closing or (iii) that RISA has not
taken all necessary action to maintain and protect each item of Intellectual
Property that RISA owns or uses.

          (b) Nothing has come to the attention of AWI which would lead AWI to
believe (i) that RISA has interfered with, infringed upon or misappropriated any
Intellectual Property Rights of third parties, (ii) that the continued operation
of the business of RISA as presently conducted will interfere with, infringe
upon or misappropriate any Intellectual Property rights of third parties, since
October 12, 1990, (iii) that RISA has received any charge, complaint, claim,
demand or notice alleging any such interference, infringement, misappropriation
or violation (including any claim that RISA must license or refrain from using
any Intellectual Property rights of any third party) and (iv) that any third
party has interfered with, infringed upon, misappropriated or otherwise come
into conflict in any material respect with any Intellectual Property rights of
RISA.

          Section 3.36. Litigation; RISA. To the knowledge of AWI, (i) there is
                        ----------------
no material suit, legal or administrative action or arbitration pending or
threatened against RISA (or, to the extent relating to the business or
properties of RISA against AWI or any

                                      28
<PAGE>
 
Subsidiary of AWI), (ii) there are no judgments, decrees or orders of any
Governmental Entity binding on RISA (or, to the extent relating to the business

instruments and shall take, or cause to be taken, all such further or other

          Section 7.8. Intercompany Accounts; Receivables. (a) AWI acknowledges
                       ----------------------------------
and agrees that, effective as of the Closing, all inter-company payables
(including intercompany notes) and receivables (other than the receivables
referred to in Sections 7.8(b) and (c)) between AWI and its Subsidiaries (other
than AO), on the one

                                      63
<PAGE>
 
hand, and AO, on the other hand, shall be deemed forgiven and/or canceled and
marked to a zero balance.

          (b) All amounts due to AO in respect of the sale prior to the Closing
of ceramic tile products by AWI shall be accounted for as receivables on the
books of AO and shall be collected by AWI consistent with past practice and paid
over to AO within 5 days of receipt thereof by AWI.

          (c) On or prior to the date 45 business days after the Closing, the
Company shall deliver to AWI a statement, certified by the chief financial
officer of the Company, setting forth, as of the Closing Date, a calculation of
the excess of receivables over current liabilities of AO (including accounts
payable, employment costs and other accrued expenses), in each case, calculated
in accordance with generally accepted accounting principles in the United States
consistently applied with the accounting principles applied by AO prior to the
Closing, to the extent such principles were consistent with generally accepted
accounting principles in the United States, (such excess the "Net Receivables
                                                              ---------------
Amount").
- ------

          (d) Within 10 business days of delivery of the statement referred to
in Section 7.8(c), AWI shall have the right to notify the Company of any
objection it has to the Net Receivables Amount as set forth in such statement.
If AWI and the Company are unable to agree on the Net Receivables Amount within
10 business days thereafter, AWI and the Company shall submit the dispute to a
nationally recognized independent accounting firm mutually agreeable to the
parties, which firm shall not have had a material relationship with either AWI
or the Company or their respective Subsidiaries within the two years preceding
the appointment (the "Arbiter"), for resolution.  If the parties cannot agree on
                      -------
the selection of the independent accounting firm to act as Arbiter, the parties
shall request the American Arbitration Association to appoint such a firm, and
such appointment shall be conclusive and binding upon the parties.  Promptly,
but no later than 20 days after its acceptance of its appointment as Arbiter,
the Arbiter shall determine, based solely on presentations by AWI and the
Company, and not by independent review, only those issues in dispute and shall
render a report as to the dispute and the resulting computation of the Net
Receivables Amount which shall be conclusive and binding upon the parties.  The
fees, costs and expenses of the Arbiter shall be borne by each party in the
proportion that the aggregate dollar amount of such disputed items so submitted
that are unsuccessfully disputed by such party bears to the aggregate dollar
amount of the items submitted to the Arbiter.

          (e) To the extent that the Net Receivables Amount, as finally
determined, (i) exceeds $15,071,000, the Company shall pay to AWI the amount of
such excess, or (ii) is less than $15,071,000, AWI shall pay to the Company the
amount of such shortfall; provided that, AWI or the Company, as the case may be,
                          -------------
shall only be

                                      64
<PAGE>
 
required to make payments under this Section 7.8(e) to the extent that such
excess or shortfall is greater than $500,000.

          (f) Any payments required to be made pursuant to this Section 7.8
shall be made by wire transfer of immediately available funds to an account
designated by the receiving party in writing.

          (g) Subject to the provisions of Section 5.2, AWI covenants and agrees
that, for the period from the date of the AO Balance Sheet, through the Closing,
it has caused and will cause the operations of AO to be conducted in the
ordinary course of business, consistent with past practice, including with
respect to the creation and payment of intercompany accounts payables and
receivables.  Schedule 7.8 specifies the existing policies of AWI and its
Subsidiaries, as of November 29, 1995, with respect to the advance and payment
of intercompany account payables and receivables between AWI and its
Subsidiaries (other than AO), on the one hand, and AO, on the other hand.

          Section 7.9. Certain RISA Closing Conditions. Notwithstanding anything
                       -------------------------------
contained in this Agreement to the contrary, in the event that the conditions
set forth in Section 11.1 relating to RISA have not been satisfied (including,
without limitations, the condition that clearance under the Mexican Anti-Trust

jurisdiction in which AO does not file its Income Tax Returns on a consolidated,
combined or unitary basis. The Company agrees that it will cooperate fully with
AWI and their counsel in the defense or compromise of any such Tax Matter
including, without limitation, the provision of any necessary powers of
attorney.

          Section 9.10. Section 338 Elections and Forms. (a) With respect to the
                        -------------------------------
Company's acquisition of the AO Shares hereunder, AWI and the Company hereby
covenant and agree with each other that they will join in making an election
under Section 338(h)(10) of the Code, and the regulations promulgated
thereunder, and any applicable analogous provision of state or local law (the
"Section 338(h)(10) Election").
 ---------------------------

          (b) The Company shall be responsible for the preparation and timely
filing of all returns (other than Income Tax Returns the responsibility for the
preparation and filing of which is governed by Section 9.3(a)), documents,
statements and other forms required to be filed with any federal, state or local
taxing authority in connection with the Section 338(h)(10) Election (the
"Section 338 Forms").  AWI shall cooperate with the Company to enable the
 -----------------
Company to prepare and file all Section 338 Forms and shall execute and deliver
to the Company such documents or forms as are required by the Code or the
regulations promulgated thereunder (and any applicable analogous provision of
state or local law) or otherwise reasonably requested to properly complete the
Section 338 Forms and to complete the Section 338(h)(10) Election.

          (c) The Consideration allocable to the AO Shares pursuant to Section
9.7 and the liabilities of AO and other relevant items shall be allocated to the
assets of AO in accordance with the rules of Section 338(h)(10) of the Code and
regulations thereunder.  Such allocation shall be prepared jointly by the
Company and AWI within 180 days following the Closing Date as reasonably
determined by the Company and AWI, based upon an appraisal prepared by American
Appraisal Associates.  All such allocations shall be used by each party in
preparing the Section 338 Forms and all relevant Tax Returns, subject to
adjustment to reflect (x) AWI's selling expenses as a reduction of sales
proceeds, and (y) Purchaser's acquisition expenses as an addition to purchase
price.

                INDEMNIFICATION OF CERTAIN ENVIRONMENTAL LOSSES
                -----------------------------------------------

          Section 10.1.  Environmental Indemnification.
                         ------------------------------

          (a) Environmental Losses Indemnified by AWI.  (i)  If the Closing
              ---------------------------------------
occurs, AWI shall defend, indemnify and hold harmless the Company Indemnitees
(excluding AWI and its Subsidiaries, but including AO), from and against all
Environmental Losses incurred by any of them relating to, resulting from, or
attributable to any Environmental Matter existing on or prior to the Closing
Date with respect to AO, including, without limitation:  (x) all manufacturing
and other facilities, quarries, mines, landfills, and any other real property
(and, in each case, any migration of Hazardous Substance therefrom) currently or
formerly owned, operated, leased or controlled by AO or any of its predecessors;
and (y) the current or former ownership or operation of the business (including,
without limitation, off-site disposal activities) of AO, or any of its
predecessors.  Collectively, such Environmental Losses shall be referred to as
"AWI Indemnified Environmental Losses."
 -------------------------------------

          (ii) AWI's indemnification obligations set forth in this Section
10.1(a)(i) shall only apply to the AWI Indemnified Environmental Losses as to
which AWI has received notification, pursuant to the procedures set forth in
Section 10.2 below, from any of the Company Indemnitees on or before:  (1) the
fifth anniversary of the Closing Date, in the case of AWI Indemnified
Environmental Losses at the AO manufacturing facilities located in Lansdale,
Pennsylvania; Olean, New York; Jackson, Tennessee; Lewisport, Kentucky; Fayette,
Alabama; and the sales service centers leased by AO set forth in Schedule
3.8(a)(iii) (the "AO Manufacturing Facilities"); and (2) the seventh anniversary
                  ---------------------------
of the Closing Date, in the case of all other AWI Indemnified Environmental
Losses, including, without limitation, at any facility, quarry, mine, landfill,
or any other real property (other than the AO Manufacturing Facilities).
Notwithstanding anything contained herein to the contrary, with respect to any
actual or potential AWI Indemnified Environmental Losses as to which AWI has
received notification pursuant to Section 10.2(h) on or prior to the applicable
anniversary of the Closing Date, AWI's indemnification obligations set forth in
Section 10.1(a)(i) shall survive without limitation as to time, irrespective of
whether any such AWI Indemnified Environmental Losses are incurred or expended
in whole or in part subsequent to the applicable anniversary of the Closing
Date.

          (iii)  AWI's indemnification obligations pursuant to Section
10.1(a)(i) shall be effective only after the amount of AWI Indemnified
Environmental Losses, in the aggregate, exceeds $1,000,000, in which case the
Company

                                      74
<PAGE>
 
Indemnitees shall be entitled to indemnification of up to $43,400,000 in
excess thereof (the "AWI Cap"), subject to reduction pursuant to Section
                     -------
10.1(b)(v).

          (iv) Notwithstanding anything to the contrary set forth herein, AWI
Indemnified Environmental Losses shall not include any Environmental Losses
relating to, resulting from, or attributable to, RISA.

          (b) Environmental Losses Indemnified by the Company.  (i)  If the
              -----------------------------------------------
Closing occurs, the Company shall defend, indemnify and hold harmless the AWI
Indemnitees from and against all Environmental Losses incurred by any of them
relating to, resulting from, or attributable to any Environmental Matter
existing at or prior to the Closing Date with respect to the Company or any
Company Subsidiary (excluding AO), including, without limitation:  (x) all
manufacturing and other facilities, quarries, mines, landfills and any other
real property (and, in each case, any migration of Hazardous Substances
therefrom) currently or formerly owned, operated, leased or controlled by the
Company or any Company Subsidiary (excluding AO), or any of their predecessors;
and (y) the current or former ownership or operation of the business (including,
without limitation, off-site disposal activities) of the Company or any Company
Subsidiary (excluding AO) or any of their predecessors; provided, however, that
                                                        -----------------
in no event shall the Company's indemnification obligations pursuant to this
Section 10.1(b) apply with respect to any Environmental Loss unless such
Environmental Loss concerns an Environmental Matter that is not otherwise
covered by the Settlement Agreement, dated May 20, 1993, entered into by and
among AEA Investors Inc., DTM Investors Inc., Dal-Tile Group Inc., Dal-Tile
Corporation, Dal-Minerals Company, and Robert M. Brittingham and John G.
Brittingham (the "Brittingham Settlement Agreement"), which is herein
                  --------------------------------
incorporated by reference.  Collectively, such Environmental Losses shall be
referred to as "Company Indemnified Environmental Losses."  For purposes of this
                ----------------------------------------
Article X, an Environmental Matter shall be deemed covered by the Brittingham
Settlement Agreement if such Environmental Matter relates to an Excess Loss (as
defined in the Brittingham Settlement Agreement), without regard to the
percentage of such Excess Loss for which the Brittinghams (as defined in the
Brittingham Settlement Agreement) are responsible pursuant to the Brittingham
Settlement Agreement.  In the case of any good faith disagreement over whether
any Company Indemnified Environmental Loss is covered by the Brittingham
Settlement Agreement, such Company Indemnified Environmental Loss shall be
deemed to be covered by the Brittingham Settlement Agreement unless and until
there is a final determination, pursuant to the dispute resolution procedures
set forth in the Brittingham Settlement Agreement, that such Company Indemnified
Environmental Loss is not covered by the Brittingham Settlement Agreement.  For
the purposes of this Section 10.1(b)(i) and Section 9.2, a Company Indemnified
Environmental Loss (or, in the case of Section 9.2, a Loss thereunder) shall be
deemed incurred by AWI if such Company Indemnified Environment Loss (or, in the
case of Section 9.2, a Loss thereunder) is incurred by the Company, but,

                                      75
<PAGE>
 
in each case, only to the extent of AWI's ownership interest in the Company at
the time AWI receives notice of the incurrence of such Loss. Payment of the
Company's indemnification obligations pursuant to this Section 10.1(b) and
pursuant to Section 9.2 shall be in cash and shall be grossed-up to make AWI
whole, taking into account AWI's direct or indirect ownership interest in the
Company at the time of payment, but only to the extent that such ownership
interest is equal to or less than 37% of the then issued and outstanding capital
stock of the Company; provided, however, that if payment in cash at the time
                      -----------------
such payment becomes due (or any requisite funding thereof by any Company
Subsidiary) would violate any covenant with respect to any outstanding Debt of
the Company or any Company Subsidiary, payment will be in the form of preferred
stock pursuant to the terms set forth on Schedule 10.1(b).

          (ii) The Company's indemnification obligations set forth in Section
10.1(b)(i) shall only apply to such Company Indemnified Environmental Losses as
to which the Company has received notification, pursuant to the procedures set
forth in Section 10.2 below, from AWI on or before:  (1) the fifth anniversary
of the Closing Date, in the case of Company Indemnified Environmental Losses at
the Company manufacturing facilities located in Coleman, Texas; Conroe, Texas;
Dallas, Texas; El Paso, Texas; Gettysburg, Pennsylvania; Pocatello, Idaho;
Monterey, Mexico; and the sales service centers leased by the Company and the
Company Subsidiaries set forth in Schedule 4.9 (the "Company Manufacturing
                                                     ---------------------
Facilities"); and (2) the seventh anniversary of the Closing Date, in the case
- ----------
of all other Company Indemnified Environmental Losses, including, without
limitation, at any facility, quarry, mine, landfill, or other real property
(other than the Company Manufacturing Facilities).  Notwithstanding anything
contained herein to the contrary, with respect to any actual or potential
Company Indemnified Environmental Losses as to which the Company has received
notification pursuant to Section 10.2(h) on or prior to the applicable
anniversary of the Closing Date, the Company's indemnification obligations set
forth in Section 10.1(b)(i) shall survive without limitation as to time,
irrespective of whether any such Company Indemnified Environmental Losses are
incurred or expended in whole or in part subsequent to the applicable
anniversary of the Closing Date.

          (iii)  The Company's indemnification obligations pursuant to Section
10.1(b)(i) shall be effective only after the amount of Company Indemnified
Environmental Losses, in the aggregate, exceeds $1,000,000, in which case AWI
shall be entitled to indemnification of up to $5,000,000 in excess thereof.

          (iv) If the Brittinghams (as defined in the Brittingham Settlement
Agreement) default in their payment obligations thereunder with respect to
Environmental Losses ("Default Losses") that, but for their coverage by the
                       --------------
Brittingham Settlement Agreement, would otherwise constitute Company Indemnified
Environmental Losses, then the AWI Cap shall be reduced by an amount equal to
the lesser of (i) the

                                      76
<PAGE>
 
amount by which such Default Losses exceed $19.3 million; (ii) $5,000,000; and
(iii) the amount by which the AWI Cap (without regard to such reduction) exceeds
indemnification payments previously made by AWI under this Article X.

          (c) "Environmental Losses" means, without limitation, any cleanup,
               --------------------
remediation, removal, or other response costs (which without limitation shall
include costs to cause AO, the Company or any Company Subsidiary to come into
compliance with Environmental Laws), investigation costs (including without
limitation fees of consultants, counsel, and other experts in connection with
any environmental investigation, testing, audits or studies), losses,
liabilities or obligations (including, without limitation, liabilities or
obligations under any lease or other contract), payments, damages (including
without limitation any actual or punitive damages under any statutory laws,
common law cause of action or contractual obligations or otherwise, including
without limitation damages (a) of third parties for personal injury (excluding
damages arising out of all third-party claims, actions, suits or proceedings
brought by current or former employees of AO, the Company or any Company
Subsidiary, other than relating to lead, chromium, cadmium, arsenic or silica)
or property damage, or (b) to natural resources), civil or criminal fines or
penalties, judgments, and amounts paid in settlement, arising out of, relating
to, resulting from, or any way attributable to any Environmental Matter or the
violation of any Environmental Law; provided, however, that Environmental Losses
                                    -----------------
shall be determined net of insurance proceeds actually received, exclusive of
collection and related costs, and without regard to any investigation or
disclosure by any of the parties hereto prior to the Closing Date.
Notwithstanding the foregoing, Environmental Losses shall not include the direct
costs of the following:  (i) capital improvements to the manufacturing
operations of AO, the Company or any Company Subsidiary, with the exception of
any of the matters set forth in Schedule 10.1(c)(i); (ii) routine internal
environmental audits and routine "Phase I" site investigations; (iii) the items
listed on Schedule 10.1(c)(iii); and (iv) the reclamation activities listed on
Schedule 10.1(c)(iv).  Notwithstanding anything to the contrary contained in the
foregoing, the definition of "Environmental Loss" shall only include matters
that would otherwise constitute Environmental Losses if such matters (or any
series of such matters relating to, resulting from, or attributable to a common
set of facts) exceed $50,000.

          Section 10.2.  Procedures Relating to Environmental Indemnification.
                         ----------------------------------------------------

          (a) After the Closing Date, the Company, in consultation with AWI,
shall have the right to plan, implement and control all actions (including
without limitation the defense of all third-party claims, actions, suits or
proceedings ("Third-Party Claims")) taken with respect to AWI Indemnified
              ------------------
Environmental Losses relating to the AO Manufacturing Facilities; provided,
                                                                  --------
however, that the Company may not compromise or settle any Third-Party Claim
- -------
relating to any such AWI Indemnified Environmental

                                      77
<PAGE>
 
Loss without the prior written consent of AWI, which consent shall not be
unreasonably withheld. Other than with respect to lead, chromium, cadmium or
arsenic, the Company shall not initiate any removal or remedial action unless
required by any Governmental Entity or Environmental Law (it being understood
that once initiated, any such action shall be conducted in a commercially
reasonable manner). The Company agrees to give AWI written notice prior to
taking any material voluntary actions with respect to lead, chromium, cadmium or
arsenic that could reasonably be expected to result in an AWI Indemnified
Environmental Loss, and agrees to plan, implement and control all actions
(including voluntary actions with respect to lead, chromium, cadmium or arsenic)
taken with respect to AWI Indemnified Environmental Losses in a commercially
reasonable manner (whether such action is taken before or after the delivery of
notice pursuant to Section 10.2(h)).

          (b) Subject to Section 10.2(c), after the Closing Date, AWI, in
consultation with the Company, shall have the right to plan, implement and
control all actions (including without limitation the defense of Third-Party
Claims) taken with respect to all actual or potential AWI Indemnified
Environmental Losses other than those relating to the AO Manufacturing
Facilities; provided, however, that AWI may not compromise or settle any Third-
            -----------------
Party Claim relating to any such AWI Indemnified Environmental Loss without the
prior written consent of the Company, which consent shall not be unreasonably
withheld.  AWI agrees to plan, implement and control all actions taken with
respect to such AWI Indemnified Environmental Losses in a commercially
reasonable manner (whether such action is taken before or after the delivery of
notice pursuant to Section 10.2(h)).  In planning, implementing and controlling
actions taken with respect to any such AWI Indemnified Environmental Loss, AWI
shall make all reasonable efforts to minimize interference with, interruption
of, disruption to, or otherwise not adversely impact the ability of AO, the
Company and the Company Subsidiaries to conduct business.  Notwithstanding the
foregoing, the Company, in consultation with AWI, shall have the right, upon
notice to AWI, to plan, implement and control all actions (including without
limitation the defense of Third-Party Claims) taken with respect to AWI
Indemnified Environmental Losses relating to all facilities (other than the AO
Manufacturing Facilities), quarries, mines, landfills, and any other real
property owned, operated, leased or controlled by AO in the event any such
facility, quarry, mine, landfill or other real property ("Property"), as the
                                                          --------
case may be, has been closed or announced for closure, sale or other disposition
following the Closing Date so long as the Company notifies AWI that the
procedures set forth in Section 10.2(c) shall apply thereto.  To the extent that
the Company exercises its right to plan, implement or control actions taken with
respect to AWI Indemnified Environmental Losses pursuant to the preceding
sentence, the standards set forth in Section 10.2(a) shall apply.

          (c) With respect to any Property as to which the Company has delivered
to AWI a notification pursuant to Section 10.2(b), and with respect to any AO

                                      78
<PAGE>
 
Manufacturing Facility, which Property or facility, in either case, has been
closed or has been announced for closure, sale or other disposition, the net
proceeds actually received from the sale of such Property or facility (net of
taxes, legal and brokerage fees, and other customary transaction fees and
expenses) shall be credited against the next indemnification obligations of AWI
under this Article X up to the amount of indemnification payments actually
received by the Company Indemnitees from AWI with respect to Environmental
Losses to the extent arising out of actions covered by Section 10.2(h)(v)
(provided that such actions were taken in connection with, or anticipation of,
such closure, sale or other disposition of such Property or facilitY).

          (d) After the Closing Date, the Company, in consultation with AWI,
shall have the right to plan, implement and control all actions with respect to
Company Indemnified Environmental Losses; provided, however, that the Company
                                          ------------------
may not compromise or settle any Third-Party Claim relating to any Company
Indemnified Environmental Losses without the prior written consent of AWI, which
consent shall not be unreasonably withheld.  The Company agrees to plan,
implement and control all actions taken with respect to Company Indemnified
Environmental Losses in a commercially reasonable manner (whether such action is
taken before or after the delivery of notice pursuant to Section 10.2(h)).

          (e) In the event of a disagreement between the Company and AWI
concerning whether any investigative, remedial or compliance-related action
taken with respect to any actual or potential Company Indemnified Environmental
Losses or AWI Indemnified Environmental Losses is commercially reasonable, the
Company and AWI shall each in good faith attempt to resolve such disagreement on
a reasonable basis with the assistance of their respective environmental
consultants; any remaining disagreements shall promptly be referred to an
independent consultant having expertise in the matter at issue, mutually
acceptable to the parties (or if the parties cannot so agree, the American
Arbitration Association shall select such a consultant who shall be independent
from each of the parties and whose fees and expenses shall be paid equally by
the parties), who shall evaluate the facts and circumstances at issue and shall
recommend a course of action which the independent consultant believes in its
good faith judgment should be taken (but shall not itself perform such course of
action).  Such recommendation shall be final and binding upon the parties.  The
parties agree to act as promptly as practicable in implementing the foregoing
procedures, and further agree that, in the event of exigent circumstances that
require any actions by the Company or AWI with respect to AWI Indemnified
Environmental Losses or Company Indemnified Environmental Losses, as the case
may be, before the foregoing procedures can be implemented, each of the Company
or AWI, as the case may be, may undertake such actions at its own expense and
shall be entitled to indemnification hereunder to the extent that its actions
are subsequently ratified by such procedure.

                                      79
<PAGE>
 
          (f) For purposes of this Section 10.2, "commercially reasonable" shall
be determined from the perspective of a reasonable business person acting
(without regard to the availability of indemnification hereunder) to achieve
compliance with Environmental Law or avoid or mitigate a loss or liability or
potential loss or liability with respect to Environmental Law or Environmental
Matters on an overall cost-effective basis to the Company; provided, however,
                                                           ------------------
that any and all actions taken by the Company or AWI, respectively, to comply
with any applicable judicial or administrative decisions, orders, decrees,
directives, permits, licenses or judgments shall be deemed to be commercially
reasonable.

          (g) Notwithstanding anything to the contrary contained in this Article
X, the Company may voluntarily disclose to any applicable Governmental Entity
any  Environmental Matter if the Company believes, in its good faith business
judgment, (exercised without regard to the availability of indemnification
hereunder), and after consultation with counsel, that such disclosure is in the
best interests of the Company (and the applicability of indemnification
hereunder shall not be affected thereby).  The Company agrees to consult with
AWI prior to any such disclosure (it being understood that in no event shall any
such consultation prevent the Company from making any such disclosure), except
in the event that such advance consultation is prohibited or rendered
impracticable by exigent circumstances, in which case the Company shall promptly
thereafter notify AWI of such disclosure.

          (h) Any party seeking indemnification under Sections 10.1(a) or
10.1(b) (the "Indemnified Party") shall promptly give written notice (a "Claim
              -----------------                                          -----
Notice") to the other party (the "Indemnifying Party") with respect to any
- ------                            ------------------
Environmental Loss actually incurred or any of the following that may result in
an Environmental Loss:  (i) actual or threatened Third-Party Claims; (ii)
judicial or administrative decisions, orders, decrees or directives; (iii)
formal notices, information requests or inquiries from, or actions taken by, any
Governmental Entity; (iv) actions (including without limitation notifications)
required by any Governmental Entity or any Environmental Law; and (v) voluntary
actions taken by the Company with respect to the presence of lead, chromium,
cadmium or arsenic (in each case, an "Environmental Claim").  Such Claim Notice
                                      -------------------
shall reasonably identify (to the extent known) the nature of such Environmental
Claim; provided, however, that failure of the Indemnified Party to give such
       -----------------
Claim Notice shall not relieve the Indemnifying Party of any of its obligations
hereunder unless and only to the extent such Indemnifying Party shall have been
prejudiced thereby.  Prior to the applicable anniversary of the Closing Date as
set forth in Section 10.1(b)(ii), the Company agrees to furnish AWI with prompt
written notice with respect to any Company Indemnified Environmental Loss
actually incurred or any of the foregoing Environmental Matters set forth in
this Section 10.2(b)(i)-(v) that the Company believes is reasonably likely to
result in a Company Indemnified Environmental Loss; provided, however, that the
                                                    -----------------
Company shall not be obligated to furnish AWI with notice of any such

                                      80
<PAGE>
 
Environmental Matter that the Company believes in good faith after reasonable
inquiry is not reasonably likely to result in Company Indemnified Environmental
Losses exceeding $50,000.

          (i) Notwithstanding the foregoing, with respect to any Environmental
Claim, the defense of which the Indemnifying Party has taken control pursuant to
this Section 10.2, the Indemnified Party shall have the right to retain separate
counsel to represent it, and the Indemnifying Party shall pay the fees and
expenses of such separate counsel if any of the following conditions occur: (i)
in the Indemnified Party's good faith judgment, it is advisable, based upon
advice from counsel, for the Indemnified Party to be represented by separate
counsel because a conflict exists or a potential conflict may exist between the
Indemnified Party and the Indemnifying Party; or (ii) the named parties to any
such Environmental Claim include both the Indemnified Party and the Indemnifying
Party, and the Indemnified Party in good faith determines that defenses are
available to it that are unavailable to the Indemnifying Party. The Indemnified
Party and the Indemnifying Party agree to cooperate with and render to each
other such assistance as may reasonably be requested in order to insure the
proper and adequate defense with respect to any such Environmental Claim which
assistance shall include, without limitation, making appropriate personnel
reasonably available for any discovery or trial.

          Section 11.1.  The Company's Obligation to Effect the Closing. The
                         ----------------------------------------------
obligation of the Company to consummate the transactions contemplated by this
Agreement is subject to the satisfaction (or waiver by the Company) as of the
Closing of the following conditions (subject, with respect to RISA, to the
provisions of Section 7.9):

          (a) The representations and warranties of AWI made in this Agreement
     qualified as to materiality shall be true and correct, and those not so
     qualified shall be true and correct in all material respects, as of the
     date hereof and as of the time of the Closing as though made as of such
     time, except to the extent such representations and warranties expressly
     relate to an earlier date (in which case such representations and
     warranties qualified as to materiality shall be true and correct, and those
     not so qualified shall be true and correct in all material respects, on and
     as of such earlier date).  AWI shall have performed or complied in all
     material respects with all obligations and covenants required by this
     Agreement to be performed or complied with by AWI by the time of the

Armstrong World Industries, Inc. Completes Transactions For Thomasville Sale
                           And American Olean Merger

  LANCASTER, Pa., Jan. 2/PRNewswire/ -- Armstrong World Industries, INC. (NYSE:
ACK) ANNOUNCED TODAY THAT IT COMPLETED THE SALE OF ITS FURNITURE SUBSIDIARY,
THOMASVILLE FURNITURE INDUSTRIES, INC., TO INTERCO INCORPORATED ON DECEMBER 29,
1995.

  The two firms previously reported (November 20) the signing of an agreement
for the sale.  Under terms of the agreement, Armstrong received approximately
$331 million in cash.  INTERCO also assumed $8 million of Thomasville debt.

  As a result of the sale, Armstrong said it will record an after-tax gain on
the transaction.  The company added that final figures will be included with its
fourth-quarter 1995 financial results to be reported in late January.

  Armstrong said that after-tax proceeds from the sale, net of fees and
expenses, were approximately $280 million.

  As reported in the November announcement, Armstrong confirmed that it expects
to use the proceeds for investment in the global growth of its core businesses
and for the continued repurchase of its shares.

  The company also announced today that it completed the combination of its
ceramic tile subsidiary, American Olean Tile Company, and Dal-Tile International
on December 29, 1995.  As previously reported, Armstrong sold 100 percent of its
stock in American Olean and contributed $27.5 million in cash to the combined
company in exchange for 37 percent of the combined entity's common stock.  The
combined company will continue to be called Dal-Tile International.

  "We are excited to have completed these two transactions, which continue the
transformation of Armstrong into a world class manufacturer and marketer of
building materials and a leader in our industry," said George A. Lorch, Chairman
and Chief Executive Officer of Armstrong.
