Segment information has been prepared in accordance with Financial Accounting
Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No.
131, "Disclosures about Segments of an Enterprise and Related Information."
Segments were determined based on products and services provided by each
segment. Accounting policies of the segments are the same as those described in
the summary of significant accounting policies. Performance of the segments is
evaluated on operating income before income taxes excluding reorganization and
restructuring charges, unusual gains and losses, and interest expense. The
Company accounts for intersegment sales and transfers as if the sales or
transfers were to third parties at current market prices.

Narrative Description of Business

The Company designs, manufactures and sells interior furnishings, including
floor coverings, building products (primarily ceiling systems), wood flooring
products, and a variety of specialty products for the building, automotive,
textile and other industries. The Company's activities extend worldwide.

Floor Coverings

The Company is a prominent worldwide manufacturer of floor coverings for the
interiors of homes and commercial and institutional buildings, with a broad
range of resilient flooring together with adhesives, installation and
maintenance materials and accessories. Resilient flooring, in both sheet and
tile form, together with laminate flooring, linoleum, carpet and sports
flooring, is made in a wide variety of types, designs, and colors. Included are
types of flooring that offer such features as ease of installation, reduced
maintenance (no-wax), and cushioning for greater underfoot comfort. Floor
covering products are sold to the commercial and residential market segments
through wholesalers, retailers (including large home centers), and contractors,
and to the hotel/motel and manufactured homes industries.

Building Products

A major producer of ceiling materials in the United States and abroad, the
Company markets both residential and commercial ceiling systems. Ceiling
materials for the home are offered in a variety of types and designs; most
provide noise reduction and incorporate Company-designed features intended to
permit ease of installation. These residential ceiling products are sold through
wholesalers and retailers (including large home centers). Commercial

ceiling systems, designed for use in shopping centers, offices, schools,
hospitals, and other commercial and institutional structures, are available in
numerous colors, performance characteristics and designs and offer
characteristics such as acoustical control, rated fire protection, and aesthetic
appeal. Commercial ceiling materials and accessories, along with acoustical wall
panels, are sold by the Company to ceiling systems contractors and to resale
distributors. Suspension ceiling systems products are manufactured and sold
through a joint venture with Worthington Industries.

Wood Products

The Company, through Triangle Pacific, manufactures and sells hardwood flooring
and other flooring and related products. The wood products segment also
manufactures and distributes kitchen and bathroom cabinets. These products are
used primarily in residential new construction and remodeling, with some
commercial applications such as retail stores and restaurants. Flooring sales
are generally made through independent wholesale flooring distributors and the
cabinets are distributed through Company-operated distributors and directly to
the end-user. The business of this segment is seasonal, with demand for its
products generally the highest between the months of April and November.

Insulation Products

The Company manufactures insulation products for the technical insulation
market. Insulation products are made in a wide variety of types and designs to
satisfy various industrial and commercial applications with the majority of the
products comprising closed cell flexible foams. A broad range of cladding and
other related materials for the insulation contracting market are also produced.
Insulation products are sold primarily throughout Europe and North America, with
increasing markets in Asia and South America.

All Other

Other business units include the making of a variety of specialty products for
the automotive, textile and other industries worldwide. Gasket materials are
sold for new and replacement use in the automotive, farm equipment, appliance,
small engine, compressor and other industries. Textile products include cots and
aprons sold to equipment manufacturers and textile mills. Gasket and textile
products are sold, depending on type and ultimate use, to original equipment
manufacturers, contractors, wholesalers, fabricators and end users.
Approximately one third of the total sales of this segment relate to three
customers. Also, prior to the disposition of the Company's equity investment in
Dal-Tile in 1998, ceramic tile for floors, walls and countertops, together with
adhesives, installation and maintenance materials and accessories were sold
through home centers, independent ceramic and floor covering wholesalers and
sales service centers operated by Dal-Tile.

                       -----------------------------------

The principal raw materials used in the manufacture of the Company's products
are synthetic resins, plasticizers, latex, linseed oil, limestone, cork, mineral
fibers and fillers, clays, starches, perlite, rubber, films, pigments, inks, oak
lumber and logs, veneer, acrylics, plywood, particleboard and fiberboard. In
addition, the Company uses a wide variety of other raw materials. Most raw
materials are purchased from sources outside of the Company. The Company also
purchases significant amounts of packaging materials for the containment and
shipment of its various products. During 1998, adequate supplies of raw
materials were available to all of the Company's industry segments.

Customers' orders for the Company's products are typically for immediate
shipment. Thus, in each industry segment, the Company has implemented inventory
systems, including its "just in time" inventory system, pursuant to which orders
are promptly filled out of inventory on hand or the product is 
 

                                       5

<PAGE>
 
manufactured to meet the delivery date specified in the order. As a result,
there historically has been no material backlog in any industry segment.

The competitive position of the Company has been enhanced by patents on products
and processes developed or perfected within the Company or obtained through
acquisition. Although the Company considers that, in the aggregate, its patents
constitute a valuable asset, it does not regard any industry segment as being
materially dependent upon any single patent or any group of related patents.

In addition, certain of the Company's trademarks, including Armstrong, Bruce,
Hartco, Robbins, and DLW, are important to the Company's business because of
their significant brand name recognition.

There is significant competition in all of the industry segments in which the
Company does business. Competition in each industry segment includes numerous
active companies (domestic and foreign), with emphasis on price, product
performance and service. In addition, with the exception of industrial and other
products and services, product styling is a significant method of competition in
the Company's industry segments. Increasing domestic competition from foreign
producers is apparent in certain industry segments and actions continue to be
taken to meet this competition.

Research and development activities are important and necessary in assisting the
Company to carry on and improve its businesses. Principal research and
development functions include the development of new products and processes and
the improvement of existing products and processes.

The Company spent $42.2 million in 1998, $47.8 million in 1997, and $55.2
million in 1996 on research and development activities worldwide for the
continuing businesses.

The Company's foreign operations are subject to foreign government legislation
involving restrictions on investments (including transfers thereof), tariff
restrictions, personnel administration, and other actions by foreign
governments. In addition, consolidated earnings are subject to both U.S. and
foreign tax laws with respect to earnings of foreign subsidiaries, and to the
effects of currency fluctuations.

ACQUISITIONS

On July 22, 1998, the Company completed its acquisition of Triangle Pacific
Corp. ("Triangle Pacific"), a Delaware corporation. Triangle Pacific is a
leading U.S. manufacturer of hardwood flooring and other flooring and related
products and a substantial manufacturer of kitchen and bathroom cabinets. The
acquisition, recorded under the purchase method of accounting, included the
purchase of outstanding shares of common stock of Triangle Pacific at $55.50 per
share which, plus acquisition costs, resulted in a total purchase price of
$911.5 million. A portion of the purchase price has been allocated to assets
acquired and liabilities assumed based on estimated fair market value at the
date of acquisition while the balance of $831.1 million was recorded as goodwill
and is being amortized over forty years on a straight-line basis.

     Effective August 31, 1998, the Company acquired approximately 93% of the
total share capital of DLW Aktiengesellschaft ("DLW"), a corporation organized 
under the laws of the Federal Republic of Germany. DLW is a leading flooring
manufacturer in Germany. The acquisition, recorded under the purchase method of
accounting, included the purchase of 93% of the total share capital of DLW
which, plus acquisition costs resulted in a total purchase price of $289.9
million. A portion of the purchase price has been allocated to assets acquired
and liabilities assumed based on fair market value at the date of acquisition
while the balance of $117.2 million was recorded as goodwill and is being
amortized over forty years on a straight-line basis. In this purchase price
allocation, $49.6 million was allocated to the estimable net realizable value of
DLW's furniture business and a carpet manufacturing business in the Netherlands,
which the Company has identified as businesses held for sale.

     The allocation of the purchase price to the businesses held for sale was
determined as follows:

- --------------------------------------------------------------------------------
(millions)                                                             1998
- --------------------------------------------------------------------------------
Estimated sales price                                                 $54.3
Less: Estimated cash outflows through disposal date                    (2.2)
      Allocated interest through disposal date                         (2.5)
- --------------------------------------------------------------------------------
Total                                                                 $49.6
- --------------------------------------------------------------------------------

     The final sales price and cash flows pertaining to these businesses may
differ from these amounts. Disposals of these businesses should occur in the
first half of 1999.

     The table below reflects the adjustment to the carrying value of the
businesses held for sale relating to interest allocation, profits and cash flows
in 1998.

Carrying value at December 31, 1998                                   $55.9
- --------------------------------------------------------------------------------

     The purchase price allocation for these acquisitions is preliminary and
further refinements are likely to be made based on the completion of final
valuation studies. The operating results of these acquired businesses have been
included in the Consolidated Statements of Earnings from the dates of
acquisition. Triangle Pacific's fiscal year ends on the Saturday closest to
December 31, which was January 2, 1999. The difference in Triangle Pacific's
fiscal year from that of the parent company was due to the difficulty in
changing its financial reporting systems to accommodate a calendar year end. No
events occurred between December 31 and January 2 at Triangle Pacific materially
affecting the Company's financial position or results of operations.

     The table below reflects unaudited pro forma combined results of the
Company, Triangle Pacific and DLW as if the acquisitions had taken place at the
beginning of fiscal 1998 and 1997:

- --------------------------------------------------------------------------------
Net sales                                          $3,479.8       $3,350.0 
Net earnings                                          (14.2)         173.2

     In management's opinion, these unaudited pro forma amounts are not
necessarily indicative of what the actual combined results of operations might
have been if the acquisitions had been effective at the beginning of fiscal 1997
and 1998.

REORGANIZATION AND OTHER ACTIONS

In 1998 the Company recognized charges of $65.6 million, or $42.6 million after
tax, related to severance and enhanced retirement benefits for more than 650
positions, approximately 75% of which were salaried positions. In addition, the
Company recorded an estimated loss of $9.0 million, or $5.9 million after tax,
related to redundant flooring products machinery and equipment held for
disposal. Reorganization actions include corporate and business unit staff
reductions reflecting reorganization of engineering, research and development
and product styling and design; realignment of support activities in connection
with implementation of a new corporate logistics and financial software system;
changes to production processes in the Company's Lancaster flooring plant; and
elimination of redundant positions in formation of a new combined business
organization for Floor Products, Corporate Retail Accounts and Installation
Products. Approximately $28.6 million is cash expenditures for severance which
will occur over the next 12 months. The remainder is a noncash charge for
enhanced retirement benefits. 

     A second-quarter 1996 restructuring charge related primarily to the
reorganization of corporate and business unit staff positions; realignment and
consolidation of the Armstrong and W.W. Henry installation products businesses;
restructuring of production processes in the Munster, Germany, ceilings
facility; early retirement opportunities for employees in the Fulton, New York,
gasket and specialty paper products facility; and write-downs of assets. These
actions affected approximately 500 employees, about two-thirds of whom were in
staff positions. The majority of the cash outflow occurred within the following
12 months. As of December 31, 1998, an immaterial amount remained in the 1996
reserve related to a non-cancelable operating lease.

     Severance payments of $10.4 million were made in 1998 for the elimination
of 209 positions related to the 1996 and 1998 reorganization and restructuring
actions.

EQUITY INVESTMENTS

Investments in affiliates were $41.8 million at December 31, 1998, a decrease of
$133.1 million, reflecting the sale of the Company's ownership of Dal-Tile,
somewhat offset by an increase in the Company's 50% interest in its WAVE joint
venture with Worthington Industries.

     Equity earnings from affiliates for 1998 primarily comprised income from a
50% interest in the WAVE joint venture and the Company's share of a net loss at
Dal-Tile and amortization of the excess of the Company's investment in Dal-Tile
over the underlying equity in net assets. Equity losses from affiliates in 1997
included $8.4 million for the Company's share of operating losses incurred by
Dal-Tile; a $29.7 million loss for the Company's share of a charge incurred by
Dal-Tile, primarily for uncollectible receivables and overstocked inventories;
and $4.3 million for the amortization of Armstrong's initial investment in
Dal-Tile over the underlying equity in net assets. Equity earnings from
affiliates for 1996 primarily comprised the Company's after-tax share of the net
income of the Dal-Tile International Inc. business combination, amortization of
the excess of the Company's investment in Dal-Tile over the underlying equity in
net assets, and earnings from its 50% interest in the WAVE joint venture.

     In 1995 the Company entered into a business combination with Dal-Tile
whereby the Company exchanged cash and the stock of its ceramic tile operations,
consisting primarily of American Olean Tile company, a wholly-owned subsidiary,
for ownership of 37% of the shares of Dal-Tile. In August 1996, Dal-Tile issued
new shares in a public offering decreasing the Company's ownership share from
37% to 33%. During 1997, the Company purchased additional shares of Dal-Tile
stock, increasing the Company's ownership to 34%.

     In 1996 Dal-Tile refinanced all of its existing debt and recorded an
extraordinary loss. The Company's share of the extraordinary loss was $8.9
million after tax or $0.21 per diluted share.

     In 1998 the Company announced its intention to dispose of its investment in
Dal-Tile. In July the Company sold 10.35 million shares of Dal-Tile at $8.50 per
share before commission and fees. Since this sale reduced the Company's
ownership of Dal-Tile below 20%, remaining shares were classified as
available-for-sale under the terms of Statement of Financial Accounting
Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity
Securities." An unrealized holding gain arising from valuing the securities at
market price was excluded from income and recognized as a separate component of
shareholders' equity.

     In October and November, the Company sold its remaining 8.02 million shares
of Dal-Tile at $8.50 per share before commission and fees. The Company recorded
a total gain of $12.8 million after tax, classified as "Other income," in the
last half of 1998 on these sales.

ENVIRONMENTAL MATTERS

The Company incurred capital expenditures of approximately $6.7 million in 1998,
$1.2 million in 1997 and $3.0 million in 1996 for environmental compliance and
control facilities and anticipates comparable annual expenditures for those
purposes for the years 1999 and 2000. The Company does not anticipate that it
will incur significant capital expenditures in order to meet the requirements of
the Clean Air Act of 1990 ("CAA") and the final implementing regulations
promulgated by various state agencies. Until all new CAA regulatory requirements
are known, uncertainty will remain regarding future estimates of capital
expenditures. 

     As with many industrial companies, Armstrong is currently involved in
proceedings under the Comprehensive Environmental Response, Compensation and
Liability Act ("Superfund"), and similar state laws at approximately 22 sites.
In most cases, Armstrong is one of many potentially responsible parties ("PRPs")
who have voluntarily agreed to jointly fund the required investigation and
remediation of each site. With regard to some sites, however, Armstrong disputes
the liability, the proposed remedy or the proposed cost allocation among the
PRPs. Armstrong may also have rights of contribution or reimbursement from other
parties or coverage under applicable insurance policies. The Company is also
remediating environmental contamination resulting from past industrial activity
at certain of its current and former plant sites.

     Estimates of future liability are based on an evaluation of currently
available facts regarding each individual site and consider factors including
existing technology, presently enacted laws and regulations and prior Company
experience in remediation of contaminated sites. Although current law imposes
joint and several liability on all parties at any Superfund site, Armstrong's
contribution to the remediation of these sites is expected to be limited by the
number of other companies also identified as potentially liable for site costs.
As a result, the Company's estimated liability reflects only the Company's
expected share. In determining the probability of contribution, the Company
considers the solvency of the parties, whether responsibility is being disputed,
the terms of any existing agreements and experience regarding similar matters.
The estimated liabilities do not take into account any claims for recoveries
from insurance or third parties. Such recoveries, where probable, have been
recorded as an asset.

     Reserves of $18.3 million at December 31, 1998, and $9.3 million at
December 31, 1997, were for potential environmental liabilities that the Company
considers probable and for which a reasonable estimate of the probable liability
could be made. Where existing data is sufficient to estimate the amount of the
liability, that estimate has been used; where only a range of probable liability
is available and no amount within that range is more likely than any other, the
lower end of the range has been used. As a result, the Company has accrued,
before agreed-to insurance coverage, $18.3 million to reflect its estimated
undiscounted liability for environmental remediation. As assessments and
remediation activities progress at each individual site, these liabilities are
reviewed to reflect additional information as it becomes available.

     Actual costs to be incurred at identified sites in the future may vary from
the estimates, given the inherent uncertainties in evaluating environmental
liabilities. Subject to the imprecision in estimating environmental remediation
costs, the Company believes that any sum it may have to pay in connection with
environmental matters in excess of the amounts noted above would not have a
material adverse effect on its financial condition, liquidity or results of
operations, although the recording of future costs may be material to earnings
in such future period.

As of December 31, 1998, the Company had approximately 18,900 active employees,
of whom approximately 6,800 are located outside the United States. About 50% of
the Company's approximately 8,800 hourly or salaried production and maintenance
employees in the United States are represented by labor unions. In February,
1999, the Company began to negotiate a new collective bargaining agreement with
the United Steel Workers of America at its Lancaster, Pennsylvania, plant.

Item 2.  Properties 
- -------------------

The Company produces and markets its products and services throughout the world,
owning and operating 69 manufacturing plants in 15 countries (including 5 plants
acquired as part of the DLW acquisition which are currently held for sale).
Forty of these facilities are located throughout the United States. The Company
also has an interest through joint ventures in an additional 17 plants in 7
countries.

Floor covering products and adhesives are produced at 27 plants with principal
manufacturing facilities located in Lancaster, Pennsylvania; Kankakee, Illinois;
Stillwater, Oklahoma; and Bietigheim-Bissingen, and Delmenhorst, Germany.
Building products are produced at 20 plants with principal facilities in Macon,
Georgia; the Florida-Alabama Gulf Coast area; and Marietta, Pennsylvania. Wood
products are produced at 17 plants, comprised of 13 wood flooring and 4 cabinet
facilities. Principal wood products facilities include Beverly, West Virginia;
Nashville and Oneida, Tennessee; and Thompsontown, Pennsylvania. Insulation
products are produced at 13 plants with the principal facility located at
Munster, Germany. Textile mill supplies, fiber gasket materials and specialty
papers and other products for industry are manufactured at 8 plants with
principal manufacturing facilities at Munster, Germany, and Fulton, New York.

Sales offices are leased worldwide, and leased facilities are utilized to
supplement the Company's owned warehousing facilities.

Productive capacity and extent of utilization of the Company's facilities are
difficult to quantify with certainty because in any one facility, maximum
capacity and utilization vary periodically depending upon the product that is
being manufactured, and individual facilities manufacture more than one type of
product. Certain manufacturing locations also provide for the manufacture of
products for more than one industry segment. In this context, the Company
estimates that the production facilities in each of its industry segments were
effectively utilized during 1998 at 80% to 90% of overall productive capacity in
meeting market conditions. Remaining productive capacity is sufficient to meet
expected customer demands.

The Company believes its various facilities are adequate and suitable.
Additional incremental investments in plant facilities are being made as
appropriate to balance capacity with anticipated demand, improve quality and
service, and reduce costs.

Item 3.  Legal Proceedings 
- --------------------------

ASBESTOS-RELATED LITIGATION

PERSONAL INJURY LITIGATION 

The Company is one of many defendants in approximately 154,000 pending claims as
of December 31, 1998, alleging personal injury from exposure to asbestos.

     Nearly all claims seek general and punitive damages arising from alleged
exposures, at various times, from World War II onward, to asbestos-containing
products. Claims against the Company generally involve allegations of
negligence, strict liability, breach of warranty and conspiracy with respect to
its involvement with asbestos-containing insulation products. The Company
discontinued the sale of all such products in 1969. The claims also allege that
injury may be determined many years (up to 40 years) after first exposure to
asbestos. Nearly all suits name many defendants, and over 100 different
companies are reportedly involved. The Company believes that many current
plaintiffs are unimpaired. A large number of claims have been settled,
dismissed, put on inactive lists or otherwise resolved, and the Company
generally is involved in all stages of claims resolution and litigation,
including individual trials, consolidated trials and appeals. Neither the rate
of future filings and resolutions nor the total number of future claims can be
predicted at this time with a high degree of certainty.

     Attention has been given by various parties to securing a comprehensive
resolution of the litigation. In 1991, the Judicial Panel for Multidistrict
Litigation ordered the transfer of federal cases to the Eastern District of
Pennsylvania in Philadelphia for pretrial purposes. The Company supported this
transfer. Some cases are periodically released for trial, although the issue of
punitive damages is retained by the transferee court. That court has been
instrumental in having the parties resolve large numbers of cases in various
jurisdictions and has been receptive to different approaches to the resolution
of claims. Claims in state courts have not been directly affected by the
transfer, although most recent cases have been filed in state courts.

Amchem Settlement Class Action

Georgine v. Amchem ("Amchem") was a settlement class action filed in the Eastern
- ------------------
District of Pennsylvania on January 15, 1993, that included essentially all
future personal injury claims against members of the Center for Claims
Resolution ("Center"), including the Company. It was designed to establish a
nonlitigation system for the resolution of such claims, and offered a method for
prompt compensation to claimants who were occupationally exposed to asbestos if
they met certain exposure and medical criteria. Compensation amounts were
derived from historical settlement data and no punitive damages were to be paid.
The settlement was designed to, among other things, minimize transactional
costs, including attorneys' fees, expedite compensation to claimants with
qualifying claims, and relieve the courts of the burden of handling future
claims.

                                      10
<PAGE>
 

     The District Court, after exhaustive discovery and testimony, approved the
settlement class action and issued a preliminary injunction that barred class
members from pursuing claims against Center members in the tort system. The U.S.
Court of Appeals for the Third Circuit reversed that decision, and the reversal
was sustained by the U.S. Supreme Court on June 25, 1997, holding that the
settlement class did not meet the requirements for class certification under
Federal Rule of Civil Procedure 23. The preliminary injunction was vacated on
July 21, 1997, resulting in the immediate reinstatement of enjoined cases and a
loss of the bar against the filing of claims in the tort system. The Company
believes that an alternative claims resolution mechanism similar to Amchem is
likely to emerge.

Recent Events 

During 1998, pending claims increased by 71,000 claims. This increase was higher
than previously anticipated. The Company and its outside counsel believe the
increase in claims filed during 1998 was partially due to acceleration of
pending claims as a result of the Supreme Court's decision on Amchem and
additional claims that had been filed in the tort system against other
defendants (and not against Center members) while Amchem was pending.


Asbestos-Related Liability

The Company continually evaluates the nature and amount of recent claim
settlements and their impact on the Company's projected asbestos resolution and
defense costs. In doing so, the Company reviews, among other things, its recent
and historical settlement amounts, the incidence of past claims, the mix of the
injuries and occupations of the plaintiffs, the number of cases pending against
it, the previous estimates based on the Amchem projection and its recent
experience. Subject to the uncertainties, limitations and other factors referred
to above and based upon its experience, the Company has estimated its share of
liability to defend and resolve probable asbestos-related personal injury
claims. The Company's estimation of such liability that is probable and
estimable through 2004 ranges from $424.7 million to $813 million. The Company
has concluded that no amount within that range is more likely than any other,
and therefore has reflected $424.7 million as a liability in the accompanying
consolidated financial statements. This estimate includes an assumption that the
number of new claims filed annually will be less than the number filed in 1998
as discussed above under "Recent Events." Of this amount, management expects to
incur approximately $80.0 million in 1999 and has reflected this amount as a
current liability. The Company believes it can reasonably estimate the number
and nature of future claims that may be filed during the next six years. However
for claims that may be filed beyond that period, management believes that the
level of uncertainty is too great to provide for reasonable estimation of the
number of future claims, the nature of such claims, or the cost to resolve them.
Accordingly, it is reasonably possible that the total exposure to personal
injury claims may be greater than the recorded liability. The increase in
recorded liability of $274.2 million in 1998 is primarily reflective of the
increases in claims filed in 1998, recent settlement experience and current
expectations about future claims. 

     Because of the uncertainties related to the number of claims, the ultimate
settlement amounts, and similar matters, it is extremely difficult to obtain
reasonable estimates of the amount of the ultimate liability. The Company's
evaluation of the range of probable liability is primarily based on known
pending claims and an estimate of potential claims that are likely to occur and
can be reasonably estimated. The estimate of likely claims to be filed in the
future is subject to a greater degree of uncertainty each year into the future.
As additional experience is gained regarding claims and settlements or other new
information becomes available regarding the potential liability, the Company
will reassess its potential liability and revise the estimates as appropriate.

     Because, among other things, payment of the liability will extend over many
years, management believes that the potential additional costs for claims net of
any potential insurance recoveries, will not have a material after-tax effect on
the financial condition of the Company or its liquidity, although the net
after-tax effect of any future liabilities recorded in excess of insurance
assets could be material to earnings in a future period.

CODEFENDANT BANKRUPTCIES

Certain codefendant companies have filed for reorganization under Chapter 11 of
the Federal Bankruptcy Code. As a consequence, litigation against them (with
some exceptions) has been stayed or restricted. Due to the uncertainties
involved, the long-term effect of these proceedings on the litigation cannot be
predicted.

PROPERTY DAMAGE LITIGATION

The Company is also one of many defendants in eight pending claims as of
December 31, 1998, brought by public and private building owners. These claims
include allegations of damage to buildings caused by asbestos-containing
products and generally seek compensatory and punitive damages and equitable
relief, including reimbursement of expenditures, for removal and replacement of
such products. Among the lawsuits that have been resolved are four class
actions, which involve public and private schools, Michigan state public and
private schools, colleges and universities, and private property owners who
leased facilities to the federal government. The Company vigorously denies the
validity of the allegations against it in these claims. These suits and claims
are not handled by the Center. Insurance coverage has been resolved and is
expected to cover almost all costs of these claims. 


                                      11
<PAGE>
 
INSURANCE COVERAGE 

The Company's primary and excess insurance policies provide product hazard and
nonproducts (general liability) coverages for personal injury claims, and
product hazard coverage for property damage claims. Certain policies also
provide coverage to ACandS, Inc., a former subsidiary of the Company. The
Company and ACandS, Inc., share certain limits that both have accessed and have
entered into an agreement that reserved for ACandS, Inc., a certain amount of
excess insurance.

     The insurance carriers that provide personal injury products hazard,
nonproducts or property damage coverages include the following: Reliance
Insurance Company; Aetna (now Travelers) Casualty and Surety Company; Liberty
Mutual Insurance Company; Travelers Insurance Company; Fireman's Fund Insurance
Company; Insurance Company of North America; Lloyds of London; various London
market companies; Fidelity and Casualty Insurance Company; First State Insurance
Company; U.S. Fire Insurance Company; Home Insurance Company; Great American
Insurance Company; American Home Assurance Company and National Union Fire
Insurance Company (now part of AIG); Central National Insurance Company;
Interstate Insurance Company; Puritan Insurance Company; and Commercial Union
Insurance Company. Midland Insurance Company, an excess carrier that provided
$25 million of personal injury coverage, certain London companies, and certain
excess carriers providing only property damage coverage are insolvent. The
Company is pursuing claims against insolvents in a number of forums.

Wellington Agreement

In 1985, the Company and 52 other companies (asbestos defendants and insurers)
signed the Wellington Agreement. This Agreement settled nearly all disputes
concerning personal injury insurance coverage with most of the Company's
carriers, provided broad coverage for both defense and indemnity and addressed
both products hazard and nonproducts (general liability) coverages. 

California Insurance Coverage Lawsuit

Trial court decisions in the insurance lawsuit filed by the Company in
California held that the trigger of coverage for personal injury claims was
continuous from exposure through death or filing of a claim, that a triggered
insurance policy should respond with full indemnification up to policy limits,
and that any defense obligation ceases upon exhaustion of policy limits.
Although not as comprehensive, another decision established favorable defense
and indemnity coverage for property damage claims, providing coverage during the
period of installation and any subsequent period in which a release of fibers
occurred. The California appellate courts substantially upheld the trial court,
and that insurance coverage litigation is now concluded. The Company has
resolved most personal injury products hazard coverage matters with its solvent
carriers through the Wellington Agreement, referred to above, or other
settlements. In 1989, a settlement with a carrier having both primary and excess
coverages provided for certain minimum and maximum percentages of costs for
personal injury claims to be allocated to nonproducts (general liability)
coverage, the percentage to be determined by negotiation or in alternative
dispute resolution ("ADR").

Asbestos Claims Facility ("Facility") and Center for Claims Resolution

The Wellington Agreement established the Facility to evaluate, settle, pay and
defend all personal injury claims against member companies. Resolution and
defense costs were allocated by formula. The Facility subsequently dissolved,
and the Center was created in October 1988 by 21 former Facility members,
including the Company. Insurance carriers, while not members, are represented ex
officio on the Center's governing board and have agreed annually to provide a
portion of the Center's operational costs. The Center adopted many of the
conceptual features of the Facility and has addressed the claims in a manner
consistent with the prompt, fair resolution of meritorious claims. Resolution
and defense costs are allocated by formula; adjustments over time have resulted
in some increased share for the Company.

Insurance Recovery Proceedings

A substantial portion of the Company's primary and excess insurance asset is
nonproducts (general liability) insurance for personal injury claims, including
among others, those that involve exposure during installation of asbestos
materials. The Wellington Agreement and the 1989 settlement agreement referred
to above have provisions for such coverage. An ADR process under the Wellington
Agreement is underway against certain carriers to determine the percentage of
resolved and unresolved claims that are nonproducts claims, to establish the
entitlement to such coverage and to determine whether and how much reinstatement
of prematurely exhausted products hazard insurance is warranted. The nonproducts
coverage potentially available is substantial and, for some policies, includes
defense costs in addition to limits. The carriers have raised various defenses,
including waiver, laches, statutes of limitations and contractual defenses. One
primary carrier alleges that it is no longer bound by the Wellington Agreement,
and another alleges that the Company agreed to limit its claims for nonproducts
coverage against that carrier when the Wellington Agreement was signed. The ADR
process is in the trial phase of binding arbitration. The Company has entered
into a settlement with a number of the carriers resolving its access to
coverage. 

                                      12

<PAGE>

     Other proceedings against non-Wellington carriers may become necessary.

     An insurance asset in the amount of $264.8 million is recorded on the
Consolidated Balance Sheet. Of this amount, approximately $26 million represents
partial settlement for previous claims which will be paid in a fixed and
determinable flow and is reported at its net present value discounted at 6.35%.
The total amount recorded reflects the Company's belief in the availability of
insurance in this amount, based upon the Company's success in insurance
recoveries, recent settlement agreements that provide such coverage, the
nonproducts recoveries by other companies and the opinion of outside counsel.
Such insurance is either available through settlement or probable of recovery
through negotiation, litigation or resolution of the ADR process which is in the
trial phase of binding arbitration. Of the $264.8 million asset, $16.0 million
has been recorded as a current asset reflecting management's estimate of the
minimum insurance payments to be received in 1999.

CONCLUSIONS 

The Company does not know how many claims will be filed against it in the
future, or the details thereof or of pending suits not fully reviewed, or the
defense and resolution costs that may ultimately result therefrom, or whether an
alternative to the Amchem settlement vehicle may emerge, or the scope of its
insurance coverage ultimately deemed available.

     The Company continually evaluates the nature and amount of recent claim
settlements and their impact on the Company's projected asbestos resolution and
defense costs. In doing so, the Company reviews, among other things, its recent
and historical settlement amounts, the incidence of past claims, the mix of the
injuries and occupations of the plaintiffs, the number of cases pending against
it, the previous estimates based on the Amchem projection and its recent
experience. Subject to the uncertainties, limitations and other factors referred
to above and based upon its experience, the Company has estimated its share of
liability to defend and resolve probable asbestos-related personal injury
claims. The Company's estimation of such liability that is probable and
estimable through 2004 ranges from $424.7 million to $813 million. The Company
has concluded that no amount within that range is more likely than any other,
and therefore has reflected $424.7 million as a liability in the accompanying
consolidated financial statements. Of this amount, management expects to incur
approximately $80.0 million in 1999 and has reflected this amount as a current
liability. The Company believes it can reasonably estimate the number and nature
of future claims that may be filed during the next six years. However for claims
that may be filed beyond that period, management believes that the level of
uncertainty is too great to provide for reasonable estimation of the number of
future claims, the nature of such claims, or the cost to resolve them.
Accordingly, it is reasonably possible that the total exposure to personal
injury claims may be greater than the recorded liability. The increase in
recorded liability of $274.2 million in 1998 is primarily reflective of the
increases in claims filed in 1998, recent settlement experience and current
expectations about future claims.

     Because of the uncertainties related to asbestos litigation, it is not
possible to precisely estimate the number of personal injury claims that may
ultimately be filed or their cost. It is reasonably possible there will be
additional claims beyond management's estimates. Management believes that the
potential additional costs for such additional claims, net of any potential
insurance recoveries, will not have a material after-tax effect on the financial
condition of the Company or its liquidity, although the net after-tax effect of
any future liabilities recorded in excess of insurance assets could be material
to earnings in a future period.

     An insurance asset in the amount of $264.8 million is recorded on the
Consolidated Balance Sheet and reflects the Company's belief in the availability
of insurance in this amount, based upon the Company's success in insurance
recoveries, settlement agreements that provide such coverage, the nonproducts
recoveries by other companies, and the opinion of outside counsel. Such
insurance is either available through settlement or probable of recovery through
the ADR process, negotiation or litigation.

     The Company believes that a claims resolution mechanism alternative to the
Amchem settlement will eventually emerge, but the liability is likely to be
higher than the projection in Amchem.

     Subject to the uncertainties, limitations and other factors referred to
elsewhere in this note and based upon its experience, the Company believes it is
probable that substantially all of the defense and resolution costs of property
damage claims will be covered by insurance. 

     Even though uncertainties remain as to the potential number of unasserted
claims and the liability resulting therefrom, and after consideration of the
factors involved, including the ultimate scope of its insurance coverage, the
Wellington Agreement and other settlements with insurance carriers, the results
of the California insurance coverage litigation, the establishment of the
Center, the likelihood that an alternative to the Amchem settlement will
eventually emerge, and its experience, the Company believes the asbestos-related
claims against the Company would not be material either to the financial
condition of the Company or to its liquidity, although the net after-tax effect
of any future liabilities recorded in excess of insurance assets could be
material to earnings in such future period.

Recent Developments
- -------------------

On February 26, 1999, the Company received a preliminary decision in the initial
phase of the trial proceeding of the ADR which was favorable to the Company on a
number of issues related to insurance coverage. The decision, while favorable,
relates to the initial phase of the ADR proceeding. The Company has not yet 
determined the financial implications of the decision.

Common Stock.

During 1998, the Company issued a total of 2,400 shares of restricted Common
Stock to nonemployee directors of the Company pursuant to the Company's
Restricted Stock Plan for Nonemployee Directors. Given the small number of
persons to whom these shares were issued, applicable restrictions on transfer
and the information regarding the Company possessed by the directors, these
shares were issued without registration in reliance on Section 4(2) of the
Securities Act of 1933, as amended.

         Results of Operations 

1998 COMPARED WITH 1997

ACQUISITIONS

On July 22, 1998, Armstrong completed its acquisition of Triangle Pacific Corp.
("Triangle Pacific"). Triangle Pacific is a leading U.S. manufacturer of
hardwood flooring and other flooring and related products and a substantial
manufacturer of kitchen and bathroom cabinets. The acquisition, recorded under
the purchase method of accounting, included the purchase of outstanding shares
of common stock of Triangle Pacific at $55.50 per share which, plus acquisition
costs, resulted in a total purchase price of $911.5 million. A portion of the
purchase price has been allocated to assets acquired and liabilities assumed
based on fair market value at the date of acquisition, while the balance of
$831.1 million was recorded as goodwill and is being amortized over forty years
on a straight-line basis. 

     Effective August 31, 1998, Armstrong acquired approximately 93% of the
total share capital of DLW Aktiengesellschaft ("DLW"), a leading flooring
manufacturer in Germany. The acquisition, recorded under the purchase method of
accounting, included the purchase of 93% of the total share capital of DLW
which, plus acquisition costs, resulted in a total purchase price of $289.9
million. A portion of the purchase price has been allocated to assets acquired
and liabilities assumed based on fair market value at the date of acquisition,
while the balance of $117.2 million was recorded as goodwill and is being
amortized over forty years on a straight-line basis. In this purchase price
allocation, $49.6 million was allocated to the estimable net realizable value of
DLW's furniture business and of a carpet manufacturing business in the
Netherlands, which the Company has identified as businesses held for sale.
Disposals of these businesses should occur in the first half of 1999. Earnings
in these businesses, which have been excluded from the Company's operating
results, were $0.4 million in 1998. Interest costs of $1.1 million were
allocated to these businesses in 1998.


The allocation of purchase price to the assets and liabilities of Triangle
Pacific and DLW was still preliminary at December 31, 1998, and further
refinements are possible. The operating results of these acquired businesses
have been included in the Consolidated Statements of Earnings from the dates of
acquisition. Triangle Pacific results are included in Armstrong's wood products
segment and DLW results are included in Armstrong's floor coverings segment.

SALE OF DAL-TILE STOCK 

In 1995 the Company entered into a business combination with Dal-Tile
International Inc. ("Dal-Tile") whereby the Company exchanged cash and the stock
of its ceramic tile operations, consisting primarily of American Olean Tile
Company, a wholly-owned subsidiary, for ownership of 37% of the shares of
Dal-Tile. In August 1996, Dal-Tile issued new shares in a public offering
there by decreasing the Company's ownership share from 37% to 33%. During 1997
the Company purchased additional shares of Dal-Tile stock, increasing the
Company's ownership to 34%.

     In 1998 the Company announced its intention to dispose of its investment in
Dal-Tile. In July the Company settled its sale of 10.35 million shares of
Dal-Tile at $8.50 per share before commission and fees. In October and November,
the Company sold its remaining 8.02 million shares of Dal-Tile at $8.50 per
share before commission and fees. The Company reported a gain of $12.8 million
after tax in 1998 on these sales.

FINANCING 

On July 13, 1998, the Company entered into a new commercial paper program and
subsequently issued $1.0 billion of commercial paper. This commercial paper,
secured by lines of credit under a bank credit facility entered into on July 17,
1998, has maturities of up to 364 days and bears interest at rates between
approximately 5.0% and 5.25% at the beginning of 1999.

     On July 15, 1998, Standard & Poor's ("S&P") lowered the ratings of the
Company's corporate credit, senior unsecured debt and revolving credit facility
to A minus from A and lowered its commercial paper rating on the Company to A-2
from A-1. On July 16, 1998, Moody's Investors Service ("Moody's") lowered the
Company's corporate credit, senior unsecured debt and revolving credit facility
ratings to Baa1 from A2 and lowered its commercial paper rating on the Company
to P-2 from P-1. Both Moody's and S&P cited factors relating to the acquisitions
of Triangle Pacific and DLW as the major reasons for their actions. It is
management's opinion that the Company has sufficient financial strength to
warrant any required support from lending institutions and financial markets.

     On August 11, 1998, the Company completed an offering of $200 million of
6.35% Senior Notes due 2003 and a concurrent offering of $150 million of 6.5%
Senior Notes due 2005. On October 28, 1998, the Company completed an offering of
$180 million of 7.45% Senior Quarterly Interest Bonds due 2038. The Company used
the proceeds to repay outstanding commercial paper. 

     On October 29, 1998, the Company completed a new bank credit facility for
$900 million which comprise a $450 million line of credit expiring in 364 days
and a $450 million line of credit expiring in five years. This facility replaced
a $1.0 billion, 364-day bank credit facility entered into on July 17, 1998.

FINANCIAL CONDITION 

As shown on the Consolidated Balance Sheets on page 28, the Company had cash and
cash equivalents of $38.2 million at December 31, 1998. As a result of
additional current assets added with the acquisitions of Triangle Pacific and
DLW, working capital at December 31, 1998, was $367.8 million compared with
$128.5 million recorded at the end of 1997. The ratio of current assets to
current liabilities was 1.49 to 1 as of December 31, 1998, compared with 1.27 to
1 as of December 31, 1997. The increase in this ratio from December 31, 1997,
primarily reflected asset and liability changes resulting from the acquisitions
of Triangle Pacific and DLW.

     Long-term debt, excluding the Company's guarantee of an ESOP loan,
increased $1,339.7 million in 1998 due to the public debt offerings mentioned
above and classification of $750.0 million of commercial paper supported by
long-term bank credit facilities as long-term debt. At December 31, 1998,
long-term debt of $1,562.8 million, or 59.3 percent of total capital, compared
with $223.1 million, or 16.7 percent of total capital, at the end of 1997. For
the periods ended December 31, 1998, and December 31, 1997, ratios of total debt
(including the Company's guarantee of an ESOP loan) as a percent of total
capital were 73.1 percent and 39.2 percent, respectively.

     As shown on the Consolidated Statements of Cash Flows on page 29, net cash
provided by operating activities for the year ended December 31, 1998, was
$252.2 million compared with $246.6 million in 1997. The increase is explained
by substantial reductions in Armstrong's pre-acquisition business units' current
assets partially offset by higher payments for asbestos claim payments prior to
insurance recoveries. 

     Net cash used for investing activities was $1,209.7 million for the year
ended December 31, 1998, compared with $152.8 million in 1997. The increase was
primarily due to expenditures for acquisitions and was partially offset by the
sale of the Company's investment in Dal-Tile.


     Net cash provided by financing activities was $937.3 million for the year
ended December 31, 1998, primarily due to the commercial paper issuance and the
three public debt offerings mentioned above. In the prior year, net cash used
for financing activities, including a net reduction in debt and the repurchase
of common shares, was $98.6 million. 

     Under plans approved by the Company's Board of Directors for the repurchase
of 5.5 million shares of common stock, the Company had repurchased approximately
4,017,000 shares through June 30, 1998. In June 1998, the Company halted open
market purchases of its common shares upon the announcement of its intent to
purchase Triangle Pacific and DLW. 

     The Company is constantly evaluating its various business units and may
from time to time dispose of, or restructure, those units. On February 2, 1999,
the Company announced its intent to form a joint venture in the worldwide
technical insulation business with NMC (USA)/Nomaco (Belgium) and Thermaflex
(Netherlands).

ASBESTOS-RELATED LITIGATION

The Company is involved in significant asbestos-related litigation which is
described more fully on pages 47-50 and which should be read in connection with
this discussion and analysis. The Company does not know how many claims will be
filed against it in the future, nor the details thereof, nor of pending suits
not fully reviewed, nor the defense and resolution costs that may ultimately
result therefrom, nor whether an alternative to the Amchem settlement vehicle
may emerge, nor the scope of its insurance coverage ultimately deemed available.

     The Company continually evaluates the nature and amount of recent claim
settlements and their impact on the Company's projected asbestos resolution and
defense costs. Subject to the uncertainties, limitations and other factors
referred to above and based upon its experience, the Company has estimated its
share of liability to defend and resolve probable asbestos-related personal
injury claims. The Company's estimation of such liability that is probable and
estimable through 2004 ranges from $424.7 million to $813 million. The Company
has concluded that no amount within that range is more likely than any other,
and therefore has recorded $424.7 million as a liability in the accompanying
consolidated financial statements. The increase of $274.2 million in recorded
liability in 1998 is primarily reflective of the increases in claims filed in
1998, recent settlement experience and current expectations about future claims.

Management estimates that the timing of the cash flows required to resolve the
recorded liability will extend beyond 2004.

     Because of the uncertainties related to asbestos litigation, it is not
possible to estimate precisely the number or cost of personal injury claims that
may ultimately be filed. The Company believes it can reasonably estimate the
number and nature of future claims that may be filed during the next six years.
However for claims that may be filed beyond that period, management believes
that the level of uncertainty is too great to provide for reasonable estimation
of the number of future claims, the nature of such claims, or the cost to
resolve them. Accordingly, it is reasonably possible that the total exposure to
personal injury claims may be greater than the recorded liability. Management
believes that the potential additional costs for such additional claims, net of
any potential insurance recoveries, will not have a material after-tax effect on
the financial condition or liquidity of the Company, although the net after-tax
effect of any future liabilities recorded in excess of insurance assets could be
material to earnings in a future period.

     An insurance asset in the amount of $264.8 million, recorded on the
Consolidated Balance Sheet, reflects the Company's belief in the availability of
insurance in this amount based upon the Company's success in insurance
recoveries, settlement agreements that provide such coverage, nonproducts
recoveries by other companies, the opinion of outside counsel, and a recent
agreement with a number of carriers. Such insurance is either available due to
settlement or probable of recovery through negotiation, litigation or resolution
of an alternative dispute resolution (ADR) process which is in the trial phase
of binding arbitration. Further, depending on the Company's future assessment of
the conclusion of the trial phase of the ADR expected in early 1999, additional
insurance assets may be available. Of the $264.8 million asset, $16.0 million
has been recorded as a current asset reflecting management's estimate of the
minimum insurance payments to be received in 1999. However, the actual amount of
payments to be received in 1999 is dependent upon the actual liability incurred
and the nature and result of settlement discussions. Management estimates that
the timing of future cash payments for the remainder of the recorded asset may
extend beyond 10 years.

     The Company believes that a claims resolution mechanism alternative to the
Amchem settlement will eventually emerge, but any liability is likely to be
higher than the projection in Amchem.

     Subject to the uncertainties, limitations and other factors previously
stated and based upon its experience, the Company believes it is probable that
substantially all of the defense and resolution costs of property damage claims
will be covered by insurance.

     Even though uncertainties remain as to the potential number of unasserted
claims and the liability resulting therefrom, and after consideration of the
factors involved, including the ultimate scope of its insurance coverage, the
Wellington Agreement and other settlements with insurance carriers, the results
of the California insurance coverage litigation, the establishment of the Center
for Claims Resolution, the likelihood that an alternative to the Amchem
settlement will eventually emerge, and its experience, the Company believes
asbestos-related claims against the Company will not be material either to the
financial condition or liquidity of the Company, although the net after-tax
effect of any future liabilities recorded in excess of insurance assets could be
material to earnings in such future period.

ACTIVITIES RELATED TO DOMCO INC.

In the fourth quarter of 1998, the Company declined to extend its cash tender
offer for all of the outstanding voting stock of Domco Inc. ("Domco"), a
Canadian flooring manufacturer. In June 1997, the Company commenced litigation
against Sommer Allibert, S.A. ("Sommer"), the majority shareholder of Domco,
alleging, among other things, that Sommer misused confidential information
provided to it by the Company and that Sommer breached a confidentiality
agreement with the Company in connection with earlier negotiations between the
Company and Sommer. That litigation remains pending in the U.S. District Court
for the Eastern District of Pennsylvania, although Sommer's counterclaim against
the Company and certain of its officers and certain of the Company's claims have
been dismissed. The Company intends to pursue its claim for damages, including
punitive damages, from Sommer. A trial date has not been set.

The Company recognized expenses arising from activities involving Domco and
Sommer totaling $12.3 million pretax, or $8.0 million after tax, in 1998.

CONSOLIDATED RESULTS

Net sales in 1998 of $2.75 billion were 24.9% higher when compared with net
sales of $2.20 billion in 1997. Triangle Pacific contributed $346.0 million of
sales and DLW $193.0 million of sales to the Company's business sales figure
before acquisitions of $2.21 billion.

     Sales were affected unfavorably by economic developments in emerging
markets. For the Company's business before acquisitions, sales increased less
than 1% in each of floor coverings, building products and insulation products.
Pacific area sales were 13.5% below 1997, although insulation products increased
both domestic sales and exports from its Panyu, China, plant. In Europe, despite
a cessation of sales to Russia in August by all business units, floor coverings
increased sales to other customers including those in Eastern Europe. In total,
emerging market turmoil reduced 1998 sales by an estimated $14.7 million versus
last year, with over three-quarters of this total from lower Russian sales.

     The Company reported a net loss of $9.3 million, or $0.23 per share,
including losses of $1.2 million related to Triangle Pacific and $2.8 million
related to DLW as well as after-tax charges of $178.2 million for an increase in
the estimated liability for asbestos-related claims and $48.5 million for cost
savings and reorganization. These results compare to net earnings of $185.0
million, or $4.50 per diluted share, in 1997.

     The Company's Economic Value Added (EVA) performance as measured by return
on EVA capital of 13.6% in 1998 exceeded the Company's cost of capital of 11%
and the return on EVA capital of 13.3% in 1997. EVA calculations exclude
financial activity related to asbestos liability claims, while reorganization
charges are treated as investments upon which a return must be earned.

     Cost of goods sold in 1998 was 67.0% of sales, higher than cost of goods
sold of 66.5% in 1997. The change reflected required purchase price accounting
adjustments related to Triangle Pacific and DLW. The Company's pre-acquisition
business had a cost of goods sold of 65.9% in 1998 due to manufacturing
efficiencies and lower raw material costs. The cost of goods sold also benefited
from several efficiency and policy savings related to the implementation of the
SAP Corporate Enterprise System, including a change in vacation policy resulting
in a $5.2 million benefit in the fourth quarter.

     Selling, general and administrative (SG&A) expenses in 1998 were $522.0
million, or 19% of sales, primarily reflecting higher advertising costs. In
1997, SG&A expenses were $383.5 million, or 17.4% of sales.

     In the fourth-quarter 1998, a noncash pretax charge of $274.2 million, or
$178.2 million after tax, was recorded for an increase in the estimated
liability for asbestos-related claims. This change primarily arose from a
greater-than-anticipated increase in personal injury filings since the Amchem
class settlement was invalidated in 1997, the Company's assessment of future
claims and recent settlements with plaintiffs' counsels. The Company also
recognized cost reduction and reorganization charges of $65.6 million, or $42.6
million after tax. This charge encompassed severance and enhanced retirement
benefits related to the termination of more than 650 positions, approximately
75% of which were salaried positions. In addition the Company recorded an
estimated loss of $9.0 million related to redundant flooring products machinery
and equipment held for disposal. Reorganization actions include corporate and
business unit staff reductions reflecting reorganization of engineering,
research and development and product styling and design; realignment of support
activities in connection with implementation of a new corporate logistics and
financial software system; changes to production processes in the Company's
Lancaster flooring plant; and elimination of redundant positions in formation of
a new combined business organization for Floor Products, Corporate Retail
Accounts and Installation Products. Approximately $28.6 million of the pretax
amount is for cash expenditures for severance which will occur over the next 12
months. The remainder is a noncash charge for enhanced retirement benefits.
Management believes that anticipated savings from the reorganization should
permit recovery of these charges in approximately two years. Severance payments
of $10.4 million in 1998 were made for the elimination of 209 positions related
to 1996 and 1998 restructuring and reorganization actions.

     Interest expense of $62.2 million in 1998 was higher than interest expense
of $28.0 million in 1997 due to higher levels of short- and long-term debt used
to finance acquisitions.

     The Company's 1998 tax benefit was generated by the charge for the increase
in asbestos liability, cost reduction and reorganization charges, and a tax
benefit associated with the gain on the sale of the Dal-Tile shares, partially
offset by the nondeductibility of goodwill in the Company's reported earnings.

INDUSTRY SEGMENT RESULTS (see pages 32 and 33)

FLOOR COVERINGS 

Worldwide floor coverings sales in 1998 of $1,317.6 million included sales of
$193.0 million from DLW. Excluding DLW, flooring sales grew over 2% in the
Americas due to strong laminate sales that more than offset a decline to
residential vinyl markets. Sales through the home center channel continued to
capture significant volume with sales increases of 16.6% over 1997. In Europe
and the Pacific area, sales were down 8%. Sales for installation products rose
3.8% over 1997.

                           [BAR CHART APPEARS HERE]

Operating income of $176.5 million in 1998, which excluded cost reduction and
reorganization charges of $53.5 million and included a loss related to DLW of
$0.7 million, compared to $186.5 million in 1997. Lower operating margins were
due to pricing pressure in North America, an unfavorable product mix, and higher
advertising expenses only partially offset by lower raw material and other
costs. The cost reduction and reorganization charges of $53.5 million relate to
reductions of hourly and salaried staff in the U.S. and foreign operations and
changes to production processes in the Company's Lancaster flooring plant.

OUTLOOK 

Sales in 1999 are expected to increase modestly due to a better mix in
the Americas in residential sheet flooring and laminates. European sales results
are anticipated to be slightly lower with weaker sales in Western Europe
reflecting price competition partially offset by more robust sales in Eastern
Europe. A more aggressive marketing program in Asia should increase sales in
that region. Operating income should improve, driven by announced cost
reductions and a favorable product mix. 

BUILDING PRODUCTS

Building products sales of $756.8 million were slightly higher than the $754.5
million in 1997, as strong sales in the U.S. commercial segments and a favorable
mix were offset by weakness in emerging markets, principally Russia and the
Pacific area, down 29.4% compared to 1997.

     Operating income of $116.6 million, which excluded cost reduction and
reorganization charges of $10.1 million, compared to $122.3 million in 1997. The
operating income decline reflected weaker performance by the business's metal
and soft fiber joint ventures in Europe and lower volumes to emerging markets,
partially offset by lower raw material and other costs. Results from the
Company's WAVE grid joint venture with Worthington Industries continue to be
strong, showing an 11% improvement over 1997. The cost reduction and
reorganization charges of $10.1 million relate to reductions of hourly and
salaried staff in the U.S. and foreign operations.

OUTLOOK

     Sales in 1999 are expected to exceed those of 1998 with the largest growth
in U.S. commercial sales. Sales are anticipated to increase in Europe with the
exception of Russia, and sales in Asia should continue to reflect depressed
market conditions. Operating income should increase in 1999 reflecting lower
manufacturing and administrative costs and improved operating income from WAVE.

                            [BAR CHART APPEARS HERE]

WOOD PRODUCTS

This segment contributed $346.0 million to sales for the period from July 22,
1998, from which time Triangle Pacific's results were consolidated in the
Company's financial statements. Sales for Triangle Pacific in 1998, although
approximately 11% ahead of sales reported by Triangle Pacific in the comparable
period in 1997, reflected competitive pricing pressures created by falling
lumber prices and imported products. 

     Operating income from the date of consolidation of $38.6 million included
the amortization of acquisition goodwill and the costs of nonrecurring purchase
price adjustments related to inventory. On a comparable basis, operating income
for Triangle Pacific in 1998 was approximately 35% above operating income
reported by Triangle Pacific in 1997.

OUTLOOK 

Triangle Pacific anticipates sales growth through its expansion of
dealer programs, continued growth of new products and improved product finishes.
Lower lumber prices, increases in sales volumes and continuing production
efficiencies should positively affect operating income. The integration of
Triangle Pacific should result in synergies as early as 1999.


                                      19

<PAGE>
 
INSULATION PRODUCTS

Sales of $230.0 million increased from $228.4 million in 1997. Sales in Europe
and the U.S. were level. Despite difficulties in the Pacific area, sales
increased from last year due to strong performance from the business's Panyu,
China, plant. Operating income of $46.3 million increased from $45.4 million in
1997, excluding cost reduction and reorganization charges of $0.2 million,
primarily due to cost cutting and SG&A expense reductions.

OUTLOOK

Price pressures in the markets for insulation products are expected to continue
into 1999. However, volume growth in sales of these products should offset this
negative pressure and result in a small operating income increase for this
business unit. 

ALL OTHER

Sales reported in this segment comprise gasket materials and textile mill
supplies. Sales of $95.8 million decreased 4% compared to 1997. The major
influence on gasket products sales was the General Motors strike. Textile sales
declined due to slow sales to European textile machinery manufacturers.
Operating income reported in this segment comprises operating income from gasket
and textile products and ceramic tile. Operating income of $9.1 million
excluding cost reduction and reorganization charges of $1.9 million compared
with a loss of $2.6 million in 1997 reflecting the absence of losses from
Dal-Tile. 

OUTLOOK 

Sales of gasket products are anticipated to continue to reflect weakness in the
automotive sector and a downturn in the diesel market. Cost containment efforts
in gasket manufacturing should offset the effect of the sales volume decline.
Textile products are expected to be affected by price pressures in 1999.


GEOGRAPHIC AREAS (SEE PAGE 33) 

Net sales in the Americas in 1998 were $1.92 billion, compared to $1.52 billion
recorded in 1997. The increase in sales to customers in the United States and
Canada was primarily due to the addition of Triangle Pacific sales. For the
Company's pre-acquisition business, sales growth continued to be strong in the
U.S. home center channel. Net sales in Europe in 1998 were $631.3 million,
compared to $488.4 million in 1997. Additional sales from DLW were somewhat
offset by lower sales to Eastern Europe, most notably Russia. Sales to
Scandinavian countries have continued to grow, reflecting increased sales from
the Swedish flooring and ceiling joint ventures. Sales to the Pacific area and
other foreign countries of $192.9 million were level with sales of $192.2
million in 1997.

     Long-lived assets in the Americas in 1998 were $1.01 billion compared to
$0.77 billion in 1997. This increase reflects additional assets from the
acquisition of Triangle Pacific. Long-lived assets in Europe in 1998 were $451.7
million compared to $163.1 million in 1997. This increase reflects additional
assets from the acquisition of DLW. Long-lived assets in the Pacific area in
1998 were $41.2 million compared to $42.2 million in 1997.

MARKET RISK 

The Company uses financial instruments, including fixed and variable rate debt,
as well as swap, forward and option contracts to finance its operations and to
hedge interest rate, currency and commodity exposures. Swap, forward and option
contracts are entered into for periods consistent with underlying exposure and
do not constitute positions independent of those exposures. The Company does not
enter into contracts for speculative purposes and is not a party to any
leveraged instruments.

Debt cash flows increased as of December 31, 1998, in comparison to December 31,
1997, as a result of financing entered into in 1998 (see page 16). In 1997 and
1998 the Company entered into forward-starting interest rate swaps designated as
hedges of long-term bonds. In 1998 the Company terminated these interest rate
swaps concurrent with the issuance of its 7.45% quarterly interest bond due
2038. The loss of $16.3 million upon termination of the swaps will be recognized
as an adjustment to interest expense over the life of the bond.

     The Company had no interest rate hedging agreements in place on December
31, 1998.

EXCHANGE RATE SENSITIVITY

     The Company uses foreign currency forward contracts to reduce the risk that
future cash flows from transactions in foreign currencies will be affected
unfavorably by changes in exchange rates.

     The table below provides anticipated net foreign cash flows for goods,
services and financing transactions for the following 12 months as of December
31, 1998, and December 31, 1997.

YEAR 2000 ACTIVITIES

The Company increased its investment in computer software in 1997 and 1998 with
projects to develop and implement a new corporate logistics system and a new
financial and human resource system. These new systems are year-2000 compliant.
In addition, a Year 2000 Project, expected to be completed in 1999, is
converting the remainder of the Company's software and hardware information
technology and noninformation technology systems to minimize any exposure to
year-2000 compliance failures. Parallel workstreams or "tracks" have been
established by the Company to complete the work required to repair or replace
noncompliant systems and monitor the degree of year-2000 compliance by
Armstrong's business partners. The workstreams encompass (a) local projects to
repair all internally developed and supported applications; (b) infrastructure
projects to repair or replace all infrastructure components (e.g., mainframe and
client server computer systems, networks, phone switches and personal
computers); and (c) remote projects to repair or replace all remote systems:
plant supported systems and applications, PLC's and other factory systems. 

     The Year 2000 Project includes several phases: an inventory phase to
identify all software and hardware components potentially affected; an
assessment phase to determine if identified components are compliant; a planning
phase to establish plans to bring components into compliance; an execution phase
to carry out needed actions determined during the planning phase; a testing
phase to verify compliance; and a completion phase to bring the revised
component into production. For the local and infrastructure tracks, the project
is currently in the testing and completion phases. For the remote track, the
project is at various phases depending upon the location.


                                      22
<PAGE>
 
     Total costs of the Year 2000 Project worldwide are estimated to be $19.1
million through 1999. Actual costs through December 1998 were $9.4 million.
Management believes internally generated funds and existing sources of liquidity
are sufficient to meet expected funding requirements for this project.

     The Company is in the process of assessing, through letters of inquiry, the
year-2000 compliance of customers and suppliers. Responses to these letters are
being evaluated for compliance, the need for follow-up actions, or contingency
plans. Until completion of this process, the Company cannot assess the potential
impact, if any, that year-2000 noncompliance by customers and suppliers may have
on the Company. Management currently believes the most reasonably-likely worst
case scenario would be that a small number of suppliers, who are not critical to
the operation of the Company's business, will be unable to supply materials for
a short time after January 1, 2000. Moreover, management is creating contingency
plans to prepare for any reasonably-likely worst case scenarios, including
manual operations, selection of alternative suppliers, early purchase of
inventory and additional software repair. 

NEW ACCOUNTING PRONOUNCEMENTS

In September 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This Statement established
accounting and reporting standards for derivative instruments and for hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. This statement is effective for all fiscal quarters
of fiscal years beginning after September 15, 1999. The adoption of this
standard is not expected to materially impact the Company's consolidated
results, financial condition or long-term liquidity.

     In April 1998, the American Institute of Certified Public Accountants
(AICPA), issued Statement of Position 98-5, Reporting on the Costs of Start-Up
Activities. This statement is effective for fiscal years beginning after
December 15, 1998. The adoption of this statement is not expected to materially
impact the Company's consolidated results, financial condition or long-term
liquidity.

1997 COMPARED WITH 1996 

FINANCIAL CONDITION 

As shown on the Consolidated Statements of Cash Flows (see page 29), the Company
had cash and cash equivalents of $57.9 million at December 31, 1997. Cash
provided by operating activities, supplemented by increases in short-term debt;
proceeds from the sale of land, facilities and other assets; and cash proceeds
from exercised stock options covered normal working capital requirements;
purchases of property, plant and equipment; payment of cash dividends;
repurchase of shares; and acquisitions and investments in joint ventures and
computer software.

     Cash provided by operating activities for the year ended December 31, 1997,
was $246.6 million compared with $220.9 million in 1996. The increase was
primarily due to higher earnings before noncash charges and lower restructuring
payments year-to-year, partially offset by a shortfall between currently
available insurance and amounts necessary to pay asbestos-related claims.
Working capital was $128.5 million as of December 31, 1997, $115.0 million lower
than the $243.5 million at year-end 1996. The ratio of current assets to current
liabilities was 1.27 to 1 as of December 31, 1997, compared with 1.76 to 1 as of
December 31, 1996. The ratio decreased from December 31, 1996, primarily due to
accrued expenses for projected short-term asbestos-related liability payments
and higher levels of short-term debt used to finance higher levels of
receivables and inventories, refinancing of long-term debt and other general
corporate purposes.

     Net cash used for investing activities was $152.8 million for the year
ended December 31, 1997, down from $239.8 million in 1996. This reduction was
primarily due to lower purchases of property, plant and equipment and higher
proceeds from the sale of land, facilities and other assets which were partially
offset by additional acquisitions and investments in joint ventures, and higher
investment in computer software.

     Net cash used for financing activities was $98.6 million for the year ended
December 31, 1997, as cash provided by higher levels of short-term debt was
offset by cash used for payment of dividends and reduction of long-term debt. In
1996, net cash used for financing activities was $171.8 million as cash was used
to reduce debt and redeem outstanding preferred stock in addition to the payment
of dividends and repurchases of stock.

     Under the 1994 and 1996 board-approved 5,500,000 common share repurchase
plans, the Company repurchased approximately 3,661,000 shares through December
31, 1997, including 1,281,000 shares repurchased in 1997.

     Long-term debt, excluding the Company's guarantee of the ESOP loan,
increased slightly in 1997. At December 31, 1997, long-term debt of $223.1
million, or 16.7% of total capital, compared with $219.4 million, or 17.4% of
total capital, at the end of 1996. The 1997 and 1996 year-end ratios of total
debt (including the Company's financing of the ESOP loan) as a percent of total
capital were 39.2% and 37.2%, respectively.

CONSOLIDATED RESULTS 

     Net sales in 1997 of $2.20 billion were 2.0% higher when compared with net
sales of $2.16 billion in 1996. Removing the currency translation impact of the
stronger U.S. dollar, sales would have increased 3.6%. Added sales from the
Swedish flooring and soft-fiber ceilings joint ventures, along with sales growth
in laminate flooring and the worldwide commercial and U.S. home center
businesses, offset sales declines in the U.S. residential sheet flooring
business.

     Net earnings of $185.0 million, or $4.50 per diluted share compared with
$155.9 million, or $3.61 per diluted share, in 1996. The increase was primarily
related to the positive impact of manufacturing productivity improvements and
some lower raw material costs in 1997 and to the negative impact of the 1996
charges for restructuring, floor discoloration product issues and the Company's
share of the extraordinary loss of Dal-Tile International Inc., in which the
Company had a 33% equity interest. Adversely affecting 1997 earnings were
ceramic tile losses of $42.4 million, or $38.6 million after tax, including $8.4
million, or $6.1 million after tax, for the Company's 34.4% share of operating
losses incurred by Dal-Tile; an additional $29.7 million before- and after-tax
loss for the Company's share of the charge incurred by Dal-Tile, primarily for
uncollectible receivables and overstocked inventories; and $4.3 million, or $2.8
million after tax, for the amortization of Armstrong's initial investment in
Dal-Tile over the underlying equity in net assets of the business combination.
Net earnings in 1996 included after-tax charges of $29.6 million for
restructuring, or $0.70 per diluted share; $22.0 million for costs associated
with the discoloration of a limited portion of flooring products, or $0.53 per
diluted share; and $8.9 million, or $0.21 per diluted share, for the Company's
share of an extraordinary loss from Dal-Tile.

     The EVA performance as measured by return on EVA capital of 13.3% in 1997
exceeded the Company's 11% cost of capital by 2.3 percentage points. In 1996,
the return on EVA capital was 14.8% and exceeded the Company's 12% cost of
capital by 2.8 percentage points. In 1997, the Company's cost of capital was
reduced to 11%, partially due to lower interest rates and stock price
volatility.

     Cost of goods sold in 1997 was 66.5% of sales, lower than the 67.7% in 1996
which included charges associated with a floor discoloration issue. Cost of
goods sold was positively affected by continued productivity improvements and
some lower raw material costs which offset some promotional pricing actions and
a less favorable product mix.

     SG&A expenses in 1997 were $383.5 million, or 17.4% of sales, which
includes the currency translation impact of the stronger U.S. dollar and some
lower advertising and administrative costs when compared with 1996. In 1996,
SG&A expenses were $410.5 million, or 19.0% of sales, and included a $14.0
million nonrecurring charge for floor discoloration.

     During 1996, the Company learned that discoloration had occurred in a
limited portion of its residential sheet flooring product lines. After
correcting the manufacturing process to eliminate any further occurrence of this
problem, the Company recorded charges of $34.0 million before tax, or $22.0
million after tax ($0.53 per diluted share), for associated inventory and claims
costs.

     In 1996, the Company incurred restructuring charges of $46.5 million, or
$29.6 million after tax ($0.70 per diluted share), related primarily to
reorganization of staff and plant positions, consolidation of the installation
products businesses, restructuring of production processes and write-down of
assets. Severance payments charged against restructuring reserves were $17.2
million in 1997 relating to the elimination of 394 positions of which 247
terminations occurred since the beginning of 1997. As of December 31, 1997, an
immaterial amount remained in the reserves for restructuring actions.

     Interest expense in 1997 of $28.0 million was higher than 1996's interest
expense of $22.6 million. The primary reason for the increase was higher levels
of short-term debt used to finance a variety of general corporate purposes.

     The Company's 1997 effective tax rate was 37.5%, negatively impacted by 3.4
percentage points from the recording of the Company's equity share of the 1997
loss from Dal-Tile. The 1996 rate of 31.4% was positively affected by 1.7
percentage points from recording the Company's equity share of the 1996 income
from Dal-Tile.

INDUSTRY SEGMENT RESULTS (see pages 32 and 33)

FLOOR COVERINGS

Worldwide floor coverings sales of $1.12 billion increased 2.2% from $1.09
billion in 1996 which included a $14.1 million reduction for product returns for
the potential discoloration of a limited portion of its product lines. The 1997
increase came primarily from the addition of sales from the laminate and Swedish
joint venture product lines and higher sales in the U.S. commercial and home
center channels. U.S. residential sheet flooring sales declined and were
adversely affected by a general weakness in high-end professionally installed
flooring, some shift toward alternative flooring products and consolidation of
the wholesaler distribution channel. 

     Operating income of $186.5 million in 1997 compared to 1996's $195.4
million, excluding 1996 charges of $34.0 million associated with the
discoloration issue and $14.5 million for restructuring primarily related to the
consolidation in the installation products business unit and other
reorganizations in the floor products operations staff. Sales increases and
productivity gains were more than offset by the negative impact of promotional
pricing, a shift in product mix to more mid-priced residential sheet flooring
and other lower margin products in the U.S. and start-up costs related to
acquisitions and new product lines. Capital expenditures for property, plant and
equipment in the floor coverings segment of $76.6 million in 1997 were directed
toward improving manufacturing processes. Capital expenditures in 1996 were
$117.7 million and were primarily related to the rollout of the Quest display
and merchandising system and toward improved manufacturing process
effectiveness.

BUILDING PRODUCTS

Net sales of $754.5 million in the building products segment increased 5% from
1996. Sales growth was experienced in all geographic areas. In the Americas,
strength came from the U.S. commercial market segment and Latin America. In
Europe, added sales from the new Swedish soft-fiber ceilings joint venture and
Eastern Europe contributed to the impact of sluggish Western European economies
and continued lower selling prices. Sales grew in the Pacific area (less than
10% of the segment's business); however, the economic slowdown in Southeast Asia
in the latter part of 1997 increased price competitiveness in this region.

     Operating income of $122.3 million increased from $103.4 million in 1996,
which excluded $8.3 million in restructuring charges. The major factors in the
1997 improvement were higher sales volume and increased productivity, reduced
raw material prices and lower startup costs in China than in 1996. In addition,
solid increases in profits were realized from the WAVE grid joint venture.
Negative factors somewhat reducing the improvement were competitive pricing
actions in the U.S. home center channel and in Western Europe. In Eastern Europe
and Russia, increased sales were concentrated in lower margin products. Capital
expenditures for property, plant and equipment were $54.4 million compared with
$67.7 million in 1996.

INSULATION PRODUCTS 

Sales of $228.4 million decreased from $246.8 million in 1996. Sales declines
from competitive market pressure in Europe were offset by increases in North
America and the Pacific area. Operating income of $45.4 million increased from
$42.4 million in 1996 excluding $2.8 million of restructuring charges, primarily
due to productivity gains in all geographic areas.

ALL OTHER 

Sales reported in this segment comprise sales of gasket materials and textile
mill supplies. Sales of $99.8 million increased from $99.4 million reported in
1996.

     Operating income reported in this segment comprises operating income from
gasket materials, textile products and ceramic tile. An operating loss of $2.6
million compared to an operating income of $11.6 million in 1996 excluding $1.2
million of restructuring charges. The 1997 loss included $8.4 million for the
Company's share of operating losses incurred by Dal-Tile International Inc., in
which the Company had a 34.4% equity interest and $4.3 million for the
amortization of the Company's initial investment in Dal-Tile over the underlying
equity in net assets of the business combination. The 1997 loss excluded a $29.7
million after-tax loss from the Company's share of a charge incurred by Dal-
Tile, primarily for uncollectible receivables and overstocked inventories. In
1996, ceramic tile reported income of $9.9 million. Profits increased in gasket
products due to the introduction of new products into European markets and an
improved cost profile. The textile products business recorded a profit in 1997
compared with a loss in 1996. Capital expenditures for property, plant and
equipment were $3.1 million compared with $2.1 million in 1996.

GEOGRAPHIC AREAS (see page 33)

Net sales in the Americas in 1997 were $1.52 billion, compared to $1.48 billion
recorded in 1998. Sales growth was strongest in the U.S. home center channel
serviced through the Corporate Retail Accounts distribution unit. Additional
growth in the Americas reflected the increase in sales to Mexico and South
America. Net sales in Europe in 1997 were $488.4 million, compared to $495.3
million in 1996. Growth from product alliances, such as Swedish flooring and
ceilings joint ventures, and sales to Central and Eastern Europe, especially
Russia were offset by lower sales to Western Europe, which reflected competitive
pricing and weakness in market economies in this area. Sales to the Pacific area
and other foreign countries of $192.2 million grew from sales of $177.5 million
in 1996. This increase primarily reflected growth in sales of insulation and
building products which benefited from manufacturing facilities in China.

</TABLE> 
Note: The sum of the quarterly earnings per-share data does not equal the total
year amounts due to changes in the average shares outstanding and, for diluted
data, the exclusion of the antidilutive effect in certain quarters. The increase
in sales and net earnings from the second to the third quarter in 1998 reflects
the Triangle Pacific and DLW acquisitions.


FOURTH QUARTER 1998 COMPARED WITH FOURTH QUARTER 1997

Net sales of $825.9 million increased 56.6% from sales of $527.4 million in the
fourth quarter of 1997. Triangle Pacific contributed $178.7 million of sales and
DLW $129.1 million of sales to the Company's pre-acquisition business sales
figure of $518.1 million. A decline in sales in the Company's pre-acquisition
businesses came from floor coverings, as solid performance from North American
residential sheet and laminates was offset by slower sales to emerging markets
and competitive price pressures in Western Europe. Sales declined in building
products as weak economic conditions in emerging markets offset strong activity
in U.S. commercial markets. Sales of insulation products increased, led by
strong sales in China. 

     The operating loss of $254.0 million compared to an operating income of
$72.2 million in the fourth quarter of 1997. Triangle Pacific contributed $21.3
million of operating income while DLW lost $0.9 million. A $274.2 million
noncash pretax charge was recorded in the fourth quarter for an increase in the
estimated liability for asbestos-related claims. An additional pretax charge of
$74.6 million related primarily to reorganization of corporate and business unit
staff positions reflecting reorganization of engineering, research and
development and product styling and design; realignment of support activities in
connection with implementation of a new software system; changes to production
processes in the Company's Lancaster flooring plant; and elimination of
redundant positions in formation of a new combined business organization for
Floor Products, Corporate Retail Accounts and Installation Products. Also
negatively impacting fourth quarter results when compared with fourth quarter
1997 were higher goodwill amortization charges related to acquisitions of
Triangle Pacific and DLW. These expenses were partially offset from an
improvement of $8.7 million in equity earnings from affiliates as the Company's
remaining investment in Dal-Tile, which produced a loss from affiliates of $8.4
million in the fourth quarter of 1997, was sold in the fourth quarter of 1998.
The sale of 8.02 million shares of Dal-Tile created a pretax gain of $6.3
million.

     For the fourth quarter, the cost of goods sold was 68.3% of sales compared
to 67.6% in 1997. Required purchase price accounting adjustments to inventories
at Triangle Pacific and DLW increased the cost of goods sold by $5.6 million,
without which gross margin percentage would have been 0.6 percentage points
better. The Company's base business cost of goods sold was 67.7%, or 0.1 points
lower than 1997, as price erosion and mix in floor coverings offset favorable
manufacturing efficiencies and lower raw material costs. The cost of goods sold
also benefited from several efficiency and policy savings related to the
implementation of the SAP Corporate Enterprise System, including a change in
vacation policy resulting in a $5.2 million benefit in the fourth quarter.

     The Company's effective tax rate in the fourth quarter of 1998 was (36.6)%
compared to an effective tax rate of 31.3% in the fourth quarter of 1997. The
difference in the tax rates is primarily due to the recognition of a tax benefit
associated with the gain on the sale of the Dal-Tile shares somewhat offset by
the nondeductibility of goodwill in the Company's reported earnings.

     The net loss was $173.4 million or $4.36 per diluted share compared to net
earnings of $46.8 million or $1.15 per diluted share in fourth quarter 1997.
Increased interest expense in addition to the asbestos liability and cost
reduction and reorganization charges were the primary reasons for the decline.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates. These financial statements are prepared in accordance with
- ----------------
generally accepted accounting principles and include management estimates and
judgments, where appropriate. Actual results may differ from these estimates.

Consolidation Policy. The consolidated financial statements and accompanying
- --------------------
data in this report include the accounts of the parent Armstrong World
Industries, Inc., and its domestic and foreign subsidiaries. All significant
intercompany transactions have been eliminated from the consolidated statements.

Earnings per Common Share. Basic earnings per share are computed by dividing the
- -------------------------
earnings available to common shareholders by the weighted average number of
shares of common stock outstanding during the year. Diluted earnings per common
share reflect the potential dilution of securities that could share in earnings.

Advertising Costs. The Company recognizes advertising expenses as they are
- -----------------
incurred.

Postretirement Benefits. The Company has plans that provide for medical and life
- -----------------------
insurance benefits to certain eligible employees when they retire from active
service. Generally, the Company's practice is to fund the actuarially determined
current service costs and the amounts necessary to amortize prior service
obligations over periods ranging up to 30 years, but not in excess of the
funding limitations.

Taxes. Deferred tax assets and liabilities are recognized using enacted tax
- -----
rates for expected future tax consequences of events recognized in the financial
statements or tax returns. The tax benefit for dividends paid on unallocated
shares of stock held by an ESOP is recognized in shareholders' equity.

Cash and Cash Equivalents. Short-term investments, substantially all of which
- -------------------------
have maturities of three months or less when purchased, are considered to be
cash equivalents and are carried at the lower of cost or an amount generally
approximating market value. 

Inventories. Inventories are valued at the lower of cost or market.
- -----------
Approximately 38% of 1998's inventories are valued using the last in, first out
(LIFO) method. Other inventories are generally determined on a first in, first
out (FIFO) method.

Long-Lived Assets. Property, plant and equipment values are stated at
- -----------------
acquisition cost, with accumulated depreciation and amortization deducted to
arrive at net book value. Depreciation charges for financial reporting purposes
are determined generally on the straight-line basis at rates calculated to
provide for the retirement of assets at the end of their useful lives as
follows: buildings, 30 years; machinery and equipment, 3 to 15 years.
Accelerated depreciation is generally used for tax purposes. Impairment losses
are recorded when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. When assets are disposed of or retired, their costs and related
depreciation are removed from the books, and any resulting gains or losses
normally are reflected in "Selling, general and administrative expenses."

     Costs of the construction of certain long-term assets include capitalized
interest which is amortized over the estimated useful life of the related asset.
Capitalized interest was $5.8 million in 1998, $1.8 million in 1997 and $2.9
million in 1996.

Goodwill and Other Intangibles. Goodwill and other intangibles are amortized on
- ------------------------------
a straight-line basis. Goodwill is amortized over periods up to 40 years while
other intangibles are amortized over periods up to 7 years. On a periodic basis,
the Company estimates the future undiscounted cash flows of the businesses to
which goodwill relates in order to ensure that the carrying value of goodwill
and other intangibles has not been impaired. 

Financial Instruments. The Company uses financial instruments to diversify or
- ---------------------
offset the effect of currency, interest rate and commodity price variability.

     The Company may enter into foreign currency forward contracts to offset the
effect of exchange rate changes on cash flow exposures denominated in foreign
currencies. Such exposures include firm commitments with third parties and
intercompany financial transactions.

     Realized gains and losses on contracts are recognized in the Consolidated
Statements of Earnings. Unrealized gains and losses on foreign currency options
that are designated as effective hedges as well as option premium expense are
deferred and included in the statements of earnings as part of the underlying
transactions. Unrealized gains and losses on foreign currency contracts used to
hedge intercompany transactions having the character of long-term investments
are included in other comprehensive income.

     The Company may enter into interest rate swap agreements to alter the
interest rate risk profile of outstanding debt, thus altering the Company's
exposure to changes in interest rates. In these swaps, the Company agrees to
exchange, at specified intervals, the difference between fixed and variable
interest amounts calculated by reference to a notional principal amount. Any
differences paid or received on interest rate swap agreements, when terminated,
are recognized as adjustments to interest rate expense over the life of
associated debt.

     The Company continuously monitors developments in the capital markets and
only enters into currency and swap transactions with established counterparties
having investment-grade ratings. Exposure to individual counterparties is
controlled, and thus the Company considers the risk of counterparty default to
be negligible.

(SFAS) No. 131, "Disclosures about Segments of an Enterprise and Related
Information." Segments were determined based on products and services provided
by each segment. Accounting policies of the segments are the same as those
described in the summary of significant accounting policies. Performance of the
segments is evaluated on operating income before income taxes excluding
reorganization and restructuring charges, unusual gains and losses, and interest
expense. The Company accounts for intersegment sales and transfers as if the
sales or transfers were to third parties at current market prices.

     The floor coverings segment includes resilient flooring, adhesives,
installation and maintenance materials and accessories sold to commercial and
residential segments through wholesalers, retailers and contractors. To reduce
interchannel conflict, distinctive resilient flooring products have been
introduced to allow exclusive product offerings by our customers. Raw materials,
especially plasticizers and resins, are a significant cost of resilient flooring
products. The Company has no influence on the worldwide market prices of these
materials and thus is subject to cost changes.

     The building products segment includes commercial and residential ceiling
systems. Grid products, manufactured through the Company's WAVE joint venture
with Worthington Industries, have become an important part of this business
worldwide. Earnings from this joint venture are included in this segment's
operating income and in "Equity Earnings from Affiliates" (see "Equity
Investments" note on page 35). The major sales activity in this segment is
commercial ceiling systems sold to resale distributors and contractors
worldwide, with European sales having a significant impact. Ceiling systems for
the residential home segment are sold through wholesalers and retailers, mainly
in the United States. Through a joint venture with a Chinese partner, a plant in
Shanghai manufactures ceilings for the Pacific area.

     The wood products segment is composed of Triangle Pacific Corp., a wholly
owned subsidiary, a leading manufacturer of consumer wood products including
hardwood flooring and cabinets. Products in this segment are used primarily in
residential new construction and remodeling and commercial applications such as
retail stores and restaurants. Approximately 40% of sales are from new
construction which is more cyclical than remodeling activity. Triangle Pacific
is the largest manufacturer in the world of hardwood flooring under the brand
names of Bruce, Hartco, Robbins, Premier and Traffic Zone. Cabinet manufacturing
is a highly fragmented industry with significant price competition. The cabinet
market is dependent on new home construction and remodeling activity.

     The insulation products segment includes flexible pipe insulation used in
construction and in original equipment manufacturing. Sales are primarily in
Europe, with Germany having the largest concentration due to its regulatory
requirements. The major product costs for insulation are raw materials and
labor. Strong competition exists in insulation since there are minimal barriers
to entry into this market.

     "All other" includes business units making a variety of specialty products
for the building, automotive, textile and other industries worldwide. Gasket
materials are sold for new and replacement use in automotive, construction and
farm equipment, appliance, small engine and compressor industries. Automotive
and diesel build rates are the most sensitive market drivers for these products.
From 1996 to 1998, the Company owned an equity interest in Dal-Tile
International Inc. ("Dal-Tile"), whose ceramic tile products are sold through
home centers, Dal-Tile sales service centers and independent distributors. In
1998 the Company sold its interest in Dal-Tile. Other products in the "all
other" category are textile mill supplies, including cots and aprons sold to
equipment manufacturers and textile mills.

ACQUISITIONS

On July 22, 1998, the Company completed its acquisition of Triangle Pacific
Corp. ("Triangle Pacific"), a Delaware corporation. Triangle Pacific is a
leading U.S. manufacturer of hardwood flooring and other flooring and related
products and a substantial manufacturer of kitchen and bathroom cabinets. The
acquisition, recorded under the purchase method of accounting, included the
purchase of outstanding shares of common stock of Triangle Pacific at $55.50 per
share which, plus acquisition costs, resulted in a total purchase price of
$911.5 million. A portion of the purchase price has been allocated to assets
acquired and liabilities assumed based on estimated fair market value at the
date of acquisition while the balance of $831.1 million was recorded as goodwill
and is being amortized over forty years on a straight-line basis.

     Effective August 31, 1998, the Company acquired approximately 93% of the
total share capital of DLW Aktiengesellschaft ("DLW"), a corporation organized
under the laws of the Federal Republic of Germany. DLW is a leading flooring
manufacturer in Germany. The acquisition, recorded under the purchase method of
accounting, included the purchase of 93% of the total share capital of DLW
which, plus acquisition costs, resulted in a total purchase price of $289.9
million. A portion of the purchase price has been allocated to assets acquired
and liabilities assumed based on the estimated fair market value at the date of
acquisition while the balance of $117.2 million was recorded as goodwill and is
being amortized over forty years on a straight-line basis. In this purchase
price allocation, $49.6 million was allocated to the estimable net realizable
value of DLW's furniture business and a carpet manufacturing business in the
Netherlands, which the Company has identified as businesses held for sale.

     The allocation of the purchase price to the businesses held for sale was
determined as follows:

- --------------------------------------------------------------------------------
(millions)                                                               1998
- --------------------------------------------------------------------------------
Estimated sales price                                                   $54.3
Less: Estimated cash outflows through disposal date                      (2.2)
      Allocated interest through disposal date                           (2.5)
- --------------------------------------------------------------------------------
Total                                                                   $49.6
- --------------------------------------------------------------------------------
                                                           
     The final sales price and cash flows pertaining to these businesses may
differ from these amounts. Disposals of these businesses should occur in the
first half of 1999.

     The table below reflects the adjustment to the carrying value of the
businesses held for sale relating to interest allocation, profits and cash flows
in 1998.

- --------------------------------------------------------------------------------

  Cash flows funded by parent                                             2.8
- --------------------------------------------------------------------------------
Carrying value at December 31, 1998                                     $55.9
- --------------------------------------------------------------------------------
                                                            
     The purchase price allocation for these acquisitions is preliminary and
further refinements are likely to be made based on the completion of final
valuation studies. The operating results of these acquired businesses have been
included in the Consolidated Statements of Earnings from the dates of
acquisition. Triangle Pacific's fiscal year ends on the Saturday closest to
December 31, which was January 2, 1999. The difference in Triangle Pacific's
fiscal year from that of the parent company was due to the difficulty in
changing its financial reporting systems to accommodate a calendar year end. No
events occurred between December 31 and January 2 at Triangle Pacific materially
affecting the Company's financial position or results of operations.

     The table below reflects unaudited pro forma combined results of the
Company, Triangle Pacific and DLW as if the acquisitions had taken place at the
beginning of fiscal 1998 and 1997:

- --------------------------------------------------------------------------------
(millions)                                   1998              1997 
- --------------------------------------------------------------------------------
Net sales                                $3,479.8          $3,350.0 
Net earnings                                (14.2)            173.2 
Net earnings per diluted share              (0.36)             4.22
- --------------------------------------------------------------------------------

     In management's opinion, these unaudited pro forma amounts are not
necessarily indicative of what the actual combined results of operations might
have been if the acquisitions had been effective at the beginning of fiscal 1997
and 1998.

REORGANIZATION AND OTHER ACTIONS

In 1998 the Company recognized charges of $65.6 million, or $42.6 million after
tax, related to severance and enhanced retirement benefits for more than 650
positions, approximately 75% of which were salaried positions. In addition, the
Company recorded an estimated loss of $9.0 million, or $5.9 million after tax,
related to redundant flooring products machinery and equipment held for
disposal. Reorganization actions include corporate and business unit staff
reductions reflecting reorganization of engineering, research and development
and product styling and design; realignment of support activities in connection
with implementation of a new corporate logistics and financial software system;
changes to production processes in the Company's Lancaster flooring plant; and
elimination of redundant positions in formation of a new combined business
organization for Floor Products, Corporate Retail Accounts and Installation
Products. Approximately $28.6 million is cash expenditures for severance which
will occur over the next 12 months. The remainder is a noncash charge for
enhanced retirement benefits. 

     A second-quarter 1996 restructuring charge related primarily to the
reorganization of corporate and business unit staff positions; realignment and
consolidation of the Armstrong and W.W. Henry installation products businesses;
restructuring of production processes in the Munster, Germany, ceilings
facility; early retirement opportunities for employees in the Fulton, New York,
gasket and specialty paper products facility; and write-downs of assets. These
actions affected approximately 500 employees, about two-thirds of whom were in
staff positions. The majority of the cash outflow occurred within the following
12 months. As of December 31, 1998, an immaterial amount remained in the 1996
reserve related to a non-cancelable operating lease.

     Severance payments of $10.4 million were made in 1998 for the elimination
of 209 positions related to the 1996 and 1998 reorganization and restructuring
actions.

EQUITY INVESTMENTS

Investments in affiliates were $41.8 million at December 31, 1998, a decrease of
$133.1 million, reflecting the sale of the Company's ownership of Dal-Tile,
somewhat offset by an increase in the Company's 50% interest in its WAVE joint
venture with Worthington Industries.

     Equity earnings from affiliates for 1998 primarily comprised income from a
50% interest in the WAVE joint venture and the Company's share of a net loss at
Dal-Tile and amortization of the excess of the Company's investment in Dal-Tile
over the underlying equity in net assets. Equity losses from affiliates in 1997
included $8.4 million for the Company's Share of operating losses incurred by
Dal-Tile; a $29.7 million loss for the Company's share of a charge incurred by
Dal-Tile, primarily for uncollectible receivables and overstocked inventories;
and $4.3 million for the amortization of Armstrong's initial investment in
Dal-Tile over the underlying equity in net assets. Equity earnings from
affiliates for 1996 primarily comprised the Company's after-tax share of the net
income of the Dal-Tile International Inc. business combination, amortization of
the excess of the Company's investment in Dal-Tile over the underlying equity in
net assets, and earnings from its 50% interest in the WAVE joint venture. 

     In 1995 the Company entered into a business combination with Dal-Tile
whereby the Company exchanged cash and the stock of its ceramic tile operations,
consisting primarily of American Olean Tile Company, a wholly-owned subsidiary,
for ownership of 37% of the shares of Dal-Tile. In August 1996, Dal-Tile issued
new shares in a public offering decreasing the Company's ownership share from
37% to 33%. During 1997, the Company purchased additional shares of Dal-Tile
stock, increasing the Company's ownership to 34%.

     In 1996 Dal-Tile refinanced all of its existing debt and recorded an
extraordinary loss. The Company's share of the extraordinary loss was $8.9
million after tax or $0.21 per diluted share. 

     In 1998 the Company announced its intention to dispose of its investment in
Dal-Tile. In July the Company sold 10.35 million shares of Dal-Tile at $8.50 per
share before commission and fees. Since this sale reduced the Company's
ownership of Dal-Tile below 20%, remaining shares were classified as
available-for-sale under the terms of Statement of Financial Accounting
Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity
Securities." An unrealized holding gain arising from valuing the securities at
market price was excluded from income and recognized as a separate component of
shareholders' equity.

     In October and November, the Company sold its remaining 8.02 million shares
of Dal-Tile at $8.50 per share before commission and fees. The Company recorded
a total gain of $12.8 million after tax, classified as "Other income," in the
last half of 1998 on these sales.

     Generally, the Company sells its products to select, preapproved customers
whose businesses are directly affected by changes in economic and market
conditions. The Company considers these factors and the financial condition of
each customer when establishing its allowance for losses from doubtful accounts.

     Trade receivables are recorded in gross billed amounts as of date of
shipment. Provision is made for estimated applicable discounts and losses.

INVENTORIES 

Approximately 38% of the Company's total inventory in 1998 and 57% in 1997 were
valued on a LIFO (last-in, first-out) basis. Inventory values were lower than
would have been reported on a total FIFO (first-in, first-out) basis, by $50.5
million at the end of 1998 and $60.3 million at year-end 1997.

     Goodwill and other intangibles increased by $968.3 million, reflecting
goodwill related to Triangle Pacific and DLW, higher spending levels in computer
software systems and acquired intangibles from acquisitions. Unamortized
computer software costs included in other intangibles were $56.0 million at
December 31, 1998, and $24.8 million at December 31, 1997.

     On August 11, 1998, the Company completed an offering of $200 million of
6.35% Senior Notes due 2003 and a concurrent offering of $150 million of 6.5%
Senior Notes due 2005. On October 28, 1998, the Company completed an offering of
$180 million of 7.45% Senior Quarterly Interest Bonds due 2038. The Company used
the proceeds from the issuance of the securities to repay outstanding commercial
paper.

     The 7.45% Senior Quarterly Interest Bonds are callable in five years and
have no sinking-fund requirements.

     The Company's 9 3/4% debentures, senior notes and medium-term notes are not
redeemable until maturity and have no sinking-fund requirements.

     The industrial development bonds mature in 2004, 2009 and 2024.

     Other debt includes an $18.6 million zero-coupon note due in 2013 that had
a carrying value of $2.8 million at December 31, 1998, and an effective interest
rate of 13.4%.

The Company has three unused credit agreements: a $450 million credit agreement
expiring in 364 days; a $450 million line of credit expiring in 2003; and a
revolving line of credit of $300 million, expiring in 2001. In addition, the
Company's foreign subsidiaries have approximately $258.9 million of unused
short-term lines of credit available from banks. The credit lines are subject to
immaterial annual commitment fees. The Company intends to refinance a portion of
its outstanding commercial paper balance on a long-term basis. Such intent is
supported by the $450 million line of credit expiring in 2003 and the $300
million revolving line of credit expiring in 2001. Accordingly, long-term debt
includes $750 million of commercial paper reclassified from short-term debt.

     In 1997 and 1998 the Company entered into forward-starting interest rate
swaps designated as hedges of long-term bonds. In 1998 the Company terminated
these interest rate swaps concurrent with the issuance of its 7.45% quarterly
interest bond due 2038. The loss of $16.3 million upon termination of the swaps
will be recognized as an adjustment to interest expense over the life of the
bond.

     Fair values were determined as follows:

     The carrying amounts of cash and cash equivalents, receivables, accounts
payable and accrued expenses, short-term debt and current installments of
long-term debt approximate fair value because of the short-term maturity of
these instruments.

     The fair value estimates of long-term debt were based upon quotes from
major financial institutions taking into consideration current rates offered to
the Company for debt of the same remaining maturities.

     Other long-term liabilities consist primarily of deferred compensation
payments, for which cost approximates fair value.

     Foreign currency contract obligations are estimated by obtaining quotes
from brokers.

     Letters of credit, financial guarantees and lines of credit amounts are
based on the estimated cost to settle the obligations.

     Natural gas contract amounts are based on estimated cost to settle the
contracts.

     The tax effects of principal temporary differences between the carrying
amounts of assets and liabilities and their tax bases are summarized in the
table below. Management believes it is more likely than not that the results of
future operations will generate sufficient taxable income to realize deferred
tax assets except for net operating losses and capital loss carryforwards. Of
the $61.1 million in capital loss carryforwards at December 31, 1998, $15.0
million will expire in 1999, $37.7 million will expire in 2001 and $8.4 million
will expire in 2003. Of the $21.3 million in foreign net operating losses, $3.3
million will expire in 2003 and the remaining $18.0 million will be carried
forward indefinitely. Valuation allowances increased $0.2 million in 1998.

     At December 31, 1998, unremitted earnings of subsidiaries outside the
United States were $155.6 million (at December 31, 1998, balance sheet exchange
rates) for which no U.S. taxes have been provided. If such earnings were to be
remitted without offsetting tax credits in the United States, withholding taxes
would be $5.4 million. The Company's intention, however, is to reinvest
unremitted earnings permanently or to repatriate them only when it is tax
effective to do so.

EMPLOYEE STOCK OWNERSHIP PLAN (ESOP)

In 1989 Armstrong established an Employee Stock Ownership Plan (ESOP) that
borrowed $270 million from banks and insurance companies, repayable over 15
years and guaranteed by the Company. The ESOP used the proceeds to purchase
5,654,450 shares of a new series of convertible preferred stock issued by the
Company. In 1996 the ESOP was merged with the Retirement Savings Plan to form
the new Retirement Savings and Stock Ownership Plan (RSSOP). On July 31, 1996,
the trustee of the ESOP converted the preferred stock held by the trust into
approximately 5.1 million shares of common stock at a one-for-one ratio.

     The number of shares released for allocation to participant accounts is
based on the proportion of principal and interest paid to the total amount of
debt service remaining to be paid over the life of the borrowings. Through
December 31, 1998, the ESOP had allocated to participants a total of 1,966,000
shares and retired 953,000 shares.

     The ESOP currently covers parent company nonunion employees and some union
employees.

     The Company's guarantee of the ESOP loan has been recorded as a long-term
obligation and as a reduction of shareholders' equity on its Consolidated
Balance Sheets.

- --------------------------------------------------------------------------------

     The Company recorded costs for the ESOP, utilizing the 80% of the shares
allocated method, of $6.9 million in 1998, $10.4 million in 1997 and $9.4
million in 1996. These costs were partially offset by savings realized from
previous changes to Company-sponsored health care benefits and elimination of
the contribution-matching feature in the Company-sponsored voluntary retirement
savings plan.

     The trustee borrowed $10.1 million from the Company in 1998, $5.5 million
in 1997, and $4.2 million in 1996. These loans were made to ensure that the
financial arrangements provided to employees remain consistent with the original
intent of the ESOP.

STOCK-BASED COMPENSATION PLANS 

Awards under the 1993 Long-Term Stock Incentive Plan may be in the form of stock
options, stock appreciation rights in conjunction with stock options,
performance restricted shares and restricted stock awards. No more than
4,300,000 shares of common stock may be issued under the Plan, and no more than
430,000 shares of common stock may be awarded in the form of restricted stock
awards. The Plan extends to April 25, 2003. Pre-1993 grants made under
predecessor plans will be governed under the provisions of those plans.

     Options are granted to purchase shares at prices not less than the closing
market price of the shares on the dates the options were granted. The options
generally become exercisable in one to three years and expire 10 years from the
date of grant.

     Performance restricted shares issuable under the 1993 Long-Term Stock
Incentive Plan entitle certain key executive employees to earn shares of
Armstrong's common stock, but only if the total Company or individual business
units meet certain predetermined performance measures during defined performance
periods (generally three years). Total Company performance measures include
Armstrong's total shareholder return relative to a peer group of 12 companies.
At the end of performance periods, common stock awarded will carry additional
restriction periods (generally three or four years), during which time the
shares will be held in custody by the Company until the expiration or
termination of restrictions. Compensation expense will be charged to earnings
over the performance period. Within performance periods at the end of 1998 were
6,600 performance restricted shares outstanding, with 777 accumulated dividend
equivalent shares. No restricted common stock awards were earned based on the
performance period ending December 31, 1998. Within restriction periods at the
end of 1998 were 182,425 shares of restricted common stock outstanding based on
performance periods ending prior to 1998.

     Restricted stock awards can be used for the purposes of recruitment,
special recognition and retention of key employees. Awards for 36,750 shares of
restricted stock were granted (excluding performance based awards discussed
above) during 1998. At the end of 1998, there were 157,334 restricted shares of
common stock outstanding.

     On January 1, 1996, the Company adopted SFAS No. 123, "Accounting for
Stock-Based Compensation," which permits entities to continue to apply the
provisions of APB Opinion No. 25 and provide pro forma net earnings and pro
forma earnings per share disclosures. Had compensation cost for these plans been
determined consistent with SFAS No. 123, the Company's net earnings and earnings
per share would have been reduced to the following pro forma amounts.

     The fair value of grants was estimated on the date of grant using the
Black-Scholes option pricing model with the assumptions for 1998, 1997 and 1996
presented in the table below. The weighted-average fair value of stock options
granted in 1998 was $17.34.

- --------------------------------------------------------------------------------

     Because the SFAS No. 123 method of accounting has not been applied to
grants prior to January 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

PENSION AND OTHER BENEFIT PROGRAMS

The Company and a number of its subsidiaries have pension plans and
postretirement medical and insurance benefit plans covering eligible employees
worldwide.

     The Company also has defined-contribution pension plans for eligible
employees. Costs for these plans were $6.9 million in 1998, $10.4 million in
1997, and $9.9 million in 1996. The Company also has an Employee Stock Ownership
Plan, as described on page 39. Benefits from the pension plan, which cover
substantially all employees and include the employees of Triangle Pacific,
acquired on July 22, 1998, are based on an employee's compensation and years of
service. Pension plans are funded by the Company. Postretirement benefits are
funded by the Company on a pay-as-you-go basis, with the retiree paying a
portion of the cost for health care benefits by means of deductibles and
contributions. The Company announced in 1989 and 1990 a 15-year phaseout of its
health care benefits for certain future retirees. These future retirees include
parent company nonunion employees and some union employees. Shares of ESOP
common stock are scheduled to be allocated to these employees, based on employee
age and years to expected retirement, to help offset future postretirement
medical costs.

     The FASB issued SFAS No. 132, "Employers' Disclosures about Pensions and
Other Postretirement Benefits," in February 1998. In accordance with this
standard, pension costs for the U.S. include those related to the pension plan
and the retirement benefit equity plan, a nonqualified pension plan. The new
standard does not change the measurement or recognition of costs for pension or
other postretirement plans. It standardizes disclosures and eliminates those
that are no longer useful. The following tables, in accordance with the new
standard, summarize the balance sheet impact, as well as the benefit
obligations, assets, funded status and rate assumptions associated with the
pension and postretirement benefit plans. The plan assets are primarily listed

     For measurement purposes, an 8% annual rate of increase in the per capita
cost of covered health care benefits was assumed for 1998. The rate was assumed
to decrease 1% per year to an ultimate rate of 6% by the year 2000.

Assumed health care cost trend rates have a significant effect on the amounts
reported for the health care plans. A one-percentage-point change in assumed
health care cost trend rates would have the following effects:

PREFERRED STOCK PURCHASE RIGHTS PLAN 

In 1996 the Board of Directors renewed the Company's 1986 shareholder rights
plan and in connection therewith declared a distribution of one right for each
share of the Company's common stock outstanding on and after January 19, 1996.
In general, the rights become exercisable at $300 per right for a fractional
share of a new series of Class A preferred stock 10 days after a person or
group, other than certain affiliates of the Company, either acquires beneficial
ownership of shares representing 20% or more of the voting power of the Company
or announces a tender or exchange offer that could result in such person or
group beneficially owning shares representing 28% or more of the voting power of
the Company. If thereafter any person or group becomes the beneficial owner of
28% or more of the voting power of the Company or if the Company is the
surviving company in a merger with a person or group that owns 20% or more of
the voting power of the Company, then each owner of a right (other than such 20%
shareholder) would be entitled to purchase shares of Company common stock having
a value equal to twice the exercise price of the right. Should the Company be
acquired in a merger or other business combination, or sell 50% or more of its
assets or earnings power, each right would entitle the holder to purchase, at
the exercise price, common shares of the acquirer having a value of twice the
exercise price of the right. The exercise price was determined on the basis of
the Board's view of the long-term value of the Company's common stock. The
rights have no voting power nor do they entitle a holder to receive dividends.
At the Company's option, the rights are redeemable prior to becoming exercisable
at five cents per right. The rights expire on March 21, 2006.

LEASES

The Company rents certain real estate and equipment. Several leases include
options for renewal or purchase and contain clauses for payment of real estate
taxes and insurance. In most cases, management expects that in the normal course
of business, leases will be renewed or replaced by other leases. Rental expense
was $26.1 million in 1998, $15.5 million in 1997, and $13.1 million in 1996.

Triangle Pacific leases a plant and related equipment in Beverly, West Virginia.
The lease agreement contains a purchase option of $1 until 2018. As a result,
the present value of the remaining future minimum lease payments is recorded as
a capitalized lease asset and related capitalized lease obligation. Assets under
this capital lease as included in the Consolidated Balance Sheets are as
follows:

Note 1: Diluted earnings (loss) per share from continuing businesses for 1998
was antidilutive.

     In 1996 the employee stock ownership plan (ESOP) and retirement savings
plan were merged resulting in the conversion of convertible preferred shares
into common stock. Basic earnings per share for "Earnings from continuing
businesses" in 1996 is determined by dividing the earnings, after deducting
preferred dividends (net of tax benefits on unallocated shares), by the average
number of common shares outstanding, including the converted ESOP shares from
the conversion date forward. Diluted earnings per share for 1996 include the
shares of common stock outstanding, the dilutive effect of stock options and the
adjustments to common shares and earnings required to portray the convertible
preferred ESOP shares on an "if-converted" basis prior to conversion.

ENVIRONMENTAL MATTERS 

The Company incurred capital expenditures of approximately $6.7 million in 1998,
$1.2 million in 1997 and $3.0 million in 1996 for environmental compliance and
control facilities and anticipates comparable annual expenditures for those
purposes for the years 1999 and 2000. The Company does not anticipate that it
will incur significant capital expenditures in order to meet the requirements of
the Clean Air Act of 1990 ("CAA") and the final implementing regulations
promulgated by various state agencies. Until all new CAA regulatory requirements
are known, uncertainty will remain regarding future estimates of capital
expenditures. 

     As with many industrial companies, Armstrong is currently involved in
proceedings under the Comprehensive Environmental Response, Compensation and
Liability Act ("Superfund"), and similar state laws at approximately 22 sites.
In most cases, Armstrong is one of many potentially responsible parties ("PRPs")
who have voluntarily agreed to jointly fund the required investigation and
remediation of each site. With regard to some sites, however, Armstrong disputes
the liability, the proposed remedy or the proposed cost allocation among the
PRPs. Armstrong may also have rights of contribution or reimbursement from other
parties or coverage under applicable insurance policies. The Company is also
remediating environmental contamination resulting from past industrial activity
at certain of its current and former plant sites.

     Estimates of future liability are based on an evaluation of currently
available facts regarding each individual site and consider factors including
existing technology, presently enacted laws and regulations and prior Company
experience in remediation of contaminated sites. Although current law imposes
joint and several liability on all parties at any Superfund site, Armstrong's
contribution to the remediation of these sites is expected to be limited by the
number of other companies also identified as potentially liable for site costs.
As a result, the Company's estimated liability reflects only the Company's
expected share. In determining the probability of contribution, the Company
considers the solvency of the parties, whether responsibility is being disputed,
the terms of any existing agreements and experience regarding similar matters.
The estimated liabilities do not take into account any claims for recoveries
from insurance or third parties. Such recoveries, where probable, have been
recorded as an asset.

     Reserves of $18.3 million at December 31, 1998, and $9.3 million at
December 31, 1997, were for potential environmental liabilities that the Company
considers probable and for which a reasonable estimate of the probable liability
could be made. Where existing data is sufficient to estimate the amount of the
liability, that estimate has been used; where only a range of probable liability
is available and no amount within that range is more likely than any other, the
lower end of the range has been used. As a result, the Company has accrued,
before agreed-to insurance coverage, $18.3 million to reflect its estimated
undiscounted liability for environmental remediation. As assessments and
remediation activities progress at each individual site, these liabilities are
reviewed to reflect additional information as it becomes available.

     Actual costs to be incurred at identified sites in the future may vary from
the estimates, given the inherent uncertainties in evaluating environmental
liabilities. Subject to the imprecision in estimating environmental remediation
costs, the Company believes that any sum it may have to pay in connection with
environmental matters in excess of the amounts noted above would not have a
material adverse effect on its financial condition, liquidity or results of
operations, although the recording of future costs may be material to earnings
in such future period.

LITIGATION AND RELATED MATTERS

ASBESTOS-RELATED LITIGATION

PERSONAL INJURY LITIGATION 

The Company is one of many defendants in approximately 154,000 pending claims as
of December 31, 1998, alleging personal injury from exposure to asbestos.

     Nearly all claims seek general and punitive damages arising from alleged
exposures, at various times, from World War II onward, to asbestos-containing
products. Claims against the Company generally involve allegations of
negligence, strict liability, breach of warranty and conspiracy with respect to
its involvement with asbestos-containing insulation products. The Company
discontinued the sale of all such products in 1969. The claims also allege that
injury may be determined many years (up to 40 years) after first exposure to
asbestos. Nearly all suits name many defendants, and over 100 different
companies are reportedly involved. The Company believes that many current
plaintiffs are unimpaired. A large number of claims have been settled,
dismissed, put on inactive lists or otherwise resolved, and the Company
generally is involved in all stages of claims resolution and litigation,
including individual trials, consolidated trials and appeals. Neither the rate
of future filings and resolutions nor the total number of future claims can be
predicted at this time with a high degree of certainty.

     Attention has been given by various parties to securing a comprehensive
resolution of the litigation. In 1991, the Judicial Panel for Multidistrict
Litigation ordered the transfer of federal cases to the Eastern District of
Pennsylvania in Philadelphia for pretrial purposes. The Company supported this
transfer. Some cases are periodically released for trial, although the issue of
punitive damages is retained by the transferee court. That court has been
instrumental in having the parties resolve large numbers of cases in various
jurisdictions and has been receptive to different approaches to the resolution
of claims. Claims in state courts have not been directly affected by the
transfer, although most recent cases have been filed in state courts.

Amchem Settlement Class Action

Georgine v. Amchem ("Amchem") was a settlement class action filed in the Eastern
- ------------------
District of Pennsylvania on January 15, 1993, that included essentially all
future personal injury claims against members of the Center for Claims
Resolution ("Center"), including the Company. It was designed to establish a
nonlitigation system for the resolution of such claims, and offered a method for
prompt compensation to claimants who were occupationally exposed to asbestos if
they met certain exposure and medical criteria. Compensation amounts were
derived from historical settlement data and no punitive damages were to be paid.
The settlement was designed to, among other things, minimize transactional
costs, including attorneys' fees, expedite compensation to claimants with
qualifying claims, and relieve the courts of the burden of handling future
claims.

     The District Court, after exhaustive discovery and testimony, approved the
settlement class action and issued a preliminary injunction that barred class
members from pursuing claims against Center members in the tort system. The U.S.
Court of Appeals for the Third Circuit reversed that decision, and the reversal
was sustained by the U.S. Supreme Court on June 25, 1997, holding that the
settlement class did not meet the requirements for class certification under
Federal Rule of Civil Procedure 23. The preliminary injunction was vacated on
July 21, 1997, resulting in the immediate reinstatement of enjoined cases and a
loss of the bar against the filing of claims in the tort system. The Company
believes that an alternative claims resolution mechanism similar to Amchem is
likely to emerge. 

Recent Events 

During 1998, pending claims increased by 71,000 claims. This increase was higher
than previously anticipated. The Company and its outside counsel believe the
increase in claims filed during 1998 was partially due to acceleration of
pending claims as a result of the Supreme Court's decision on Amchem and
additional claims that had been filed in the tort system against other
defendants (and not against Center members) while Amchem was pending.

Asbestos-Related Liability

The Company continually evaluates the nature and amount of recent claim
settlements and their impact on the Company's projected asbestos resolution and
defense costs. In doing so, the Company reviews, among other things, its recent
and historical settlement amounts, the incidence of past claims, the mix of the
injuries and occupations of the plaintiffs, the number of cases pending against
it, the previous estimates based on the Amchem projection and its recent
experience. Subject to the uncertainties, limitations and other factors referred
to above and based upon its experience, the Company has estimated its share of
liability to defend and resolve probable asbestos-related personal injury
claims. The Company's estimation of such liability that is probable and
estimable through 2004 ranges from $424.7 million to $813 million. The Company
has concluded that no amount within that range is more likely than any other,
and therefore has reflected $424.7 million as a liability in the accompanying
consolidated financial statements. This estimate includes an assumption that the
number of new claims filed annually will be less than the number filed in 1998
as discussed above under "Recent Events." Of this amount, management expects to
incur approximately $80.0 million in 1999 and has reflected this amount as a
current liability. The Company believes it can reasonably estimate the number
and nature of future claims that may be filed during the next six years. However
for claims that may be filed beyond that period, management believes that the
level of uncertainty is too great to provide for reasonable estimation of the
number of future claims, the nature of such claims, or the cost to resolve them.
Accordingly, it is reasonably possible that the total exposure to personal
injury claims may be greater than the recorded liability. The increase in
recorded liability of $274.2 million in 1998 is primarily reflective of the
increases in claims filed in 1998, recent settlement experience and current
expectations about future claims. 

     Because of the uncertainties related to the number of claims, the ultimate
settlement amounts, and similar matters, it is extremely difficult to obtain
reasonable estimates of the amount of the ultimate liability. The Company's
evaluation of the range of probable liability is primarily based on known
pending claims and an estimate of potential claims that are likely to occur and
can be reasonably estimated. The estimate of likely claims to be filed in the
future is subject to a greater degree of uncertainty each year into the future.
As additional experience is gained regarding claims and settlements or other new
information becomes available regarding the potential liability, the Company
will reassess its potential liability and revise the estimates as appropriate.

     Because, among other things, payment of the liability will extend over many
years, management believes that the potential additional costs for claims net of
any potential insurance recoveries, will not have a material after-tax effect on
the financial condition of the Company or its liquidity, although the net
after-tax effect of any future liabilities recorded in excess of insurance
assets could be material to earnings in a future period.

CODEFENDANT BANKRUPTCIES

Certain codefendant companies have filed for reorganization under Chapter 11 of
the Federal Bankruptcy Code. As a consequence, litigation against them (with
some exceptions) has been stayed or restricted. Due to the uncertainties
involved, the long-term effect of these proceedings on the litigation cannot be
predicted.

PROPERTY DAMAGE LITIGATION

The Company is also one of many defendants in eight pending claims as of
December 31, 1998, brought by public and private building owners. These claims
include allegations of damage to buildings caused by asbestos-containing
products and generally seek compensatory and punitive damages and equitable
relief, including reimbursement of expenditures, for removal and replacement of
such products. Among the lawsuits that have been resolved are four class
actions, which involve public and private schools, Michigan state public and
private schools, colleges and universities, and private property owners who
leased facilities to the federal government. The Company vigorously denies the
validity of the allegations against it in these claims. These suits and claims
are not handled by the Center. Insurance coverage has been resolved and is
expected to cover almost all costs of these claims. 

INSURANCE COVERAGE 

The Company's primary and excess insurance policies provide product hazard and
nonproducts (general liability) coverages for personal injury claims, and
product hazard coverage for property damage claims. Certain policies also
provide coverage to ACandS, Inc., a former subsidiary of the Company. The
Company and ACandS, Inc., share certain limits that both have accessed and have
entered into an agreement that reserved for ACandS, Inc., a certain amount of
excess insurance.

     The insurance carriers that provide personal injury products hazard,
nonproducts or property damage coverages include the following: Reliance
Insurance Company; Aetna (now Travelers) Casualty and Surety Company; Liberty
Mutual Insurance Company; Travelers Insurance Company; Fireman's Fund Insurance
Company; Insurance Company of North America; Lloyds of London; various London
market companies; Fidelity and Casualty Insurance Company; First State Insurance
Company; U.S. Fire Insurance Company; Home Insurance Company; Great American
Insurance Company; American Home Assurance Company and National Union Fire
Insurance Company (now part of AIG); Central National Insurance Company;
Interstate Insurance Company; Puritan Insurance Company; and Commercial Union
Insurance Company. Midland Insurance Company, an excess carrier that provided
$25 million of personal injury coverage, certain London companies, and certain
excess carriers providing only property damage coverage are insolvent. The
Company is pursuing claims against insolvents in a number of forums.

Wellington Agreement

In 1985, the Company and 52 other companies (asbestos defendants and insurers)
signed the Wellington Agreement. This Agreement settled nearly all disputes
concerning personal injury insurance coverage with most of the Company's
carriers, provided broad coverage for both defense and indemnity and addressed
both products hazard and nonproducts (general liability) coverages. 

California Insurance Coverage Lawsuit 

Trial court decisions in the insurance lawsuit filed by the Company in
California held that the trigger of coverage for personal injury claims was
continuous from exposure through death or filing of a claim, that a triggered
insurance policy should respond with full indemnification up to policy limits,
and that any defense obligation ceases upon exhaustion of policy limits.
Although not as comprehensive, another decision established favorable defense
and indemnity coverage for property damage claims, providing coverage during the
period of installation and any subsequent period in which a release of fibers
occurred. The California appellate courts substantially upheld the trial court,
and that insurance coverage litigation is now concluded. The Company has
resolved most personal injury products hazard coverage matters with its solvent
carriers through the Wellington Agreement, referred to above, or other
settlements. In 1989, a settlement with a carrier having both primary and excess
coverages provided for certain minimum and maximum percentages of costs for
personal injury claims to be allocated to nonproducts (general liability)
coverage, the percentage to be determined by negotiation or in alternative
dispute resolution ("ADR"). 

Asbestos Claims Facility ("Facility") and Center for Claims Resolution

The Wellington Agreement established the Facility to evaluate, settle, pay and
defend all personal injury claims against member companies. Resolution and
defense costs were allocated by formula. The Facility subsequently dissolved,
and the Center was created in October 1988 by 21 former Facility members,
including the Company. Insurance carriers, while not members, are represented ex
officio on the Center's governing board and have agreed annually to provide a
portion of the Center's operational costs. The Center adopted many of the
conceptual features of the Facility and has addressed the claims in a manner
consistent with the prompt, fair resolution of meritorious claims. Resolution
and defense costs are allocated by formula; adjustments over time have resulted
in some increased share for the Company.

Insurance Recovery Proceedings

A substantial portion of the Company's primary and excess insurance asset is
nonproducts (general liability) insurance for personal injury claims, including
among others, those that involve exposure during installation of asbestos
materials. The Wellington Agreement and the 1989 settlement agreement referred
to above have provisions for such coverage. An ADR process under the Wellington
Agreement is underway against certain carriers to determine the percentage of
resolved and unresolved claims that are nonproducts claims, to establish the
entitlement to such coverage and to determine whether and how much reinstatement
of prematurely exhausted products hazard insurance is warranted. The nonproducts
coverage potentially available is substantial and, for some policies, includes
defense costs in addition to limits. The carriers have raised various defenses,
including waiver, laches, statutes of limitations and contractual defenses. One
primary carrier alleges that it is no longer bound by the Wellington Agreement,
and another alleges that the Company agreed to limit its claims for nonproducts
coverage against that carrier when the Wellington Agreement was signed. The ADR
process is in the trial phase of binding arbitration. The Company has entered
into a settlement with a number of the carriers resolving its access to
coverage.

                                      49

<PAGE>
 

     Other proceedings against non-Wellington carriers may become necessary.

     An insurance asset in the amount of $264.8 million is recorded on the
Consolidated Balance Sheet. Of this amount, approximately $26 million represents
partial settlement for previous claims which will be paid in a fixed and
determinable flow and is reported at its net present value discounted at 6.35%.
The total amount recorded reflects the Company's belief in the availability of
insurance in this amount, based upon the Company's success in insurance
recoveries, recent settlement agreements that provide such coverage, the
nonproducts recoveries by other companies and the opinion of outside counsel.
Such insurance is either available through settlement or probable of recovery
through negotiation, litigation or resolution of the ADR process which is in the
trial phase of binding arbitration. Of the $264.8 million asset, $16.0 million
has been recorded as a current asset reflecting management's estimate of the
minimum insurance payments to be received in 1999. 

CONCLUSIONS 

The Company does not know how many claims will be filed against it in the
future, or the details thereof or of pending suits not fully reviewed, or the
defense and resolution costs that may ultimately result therefrom, or whether an
alternative to the Amchem settlement vehicle may emerge, or the scope of its
insurance coverage ultimately deemed available.

     The Company continually evaluates the nature and amount of recent claim
settlements and their impact on the Company's projected asbestos resolution and
defense costs. In doing so, the Company reviews, among other things, its recent
and historical settlement amounts, the incidence of past claims, the mix of the
injuries and occupations of the plaintiffs, the number of cases pending against
it, the previous estimates based on the Amchem projection and its recent
experience. Subject to the uncertainties, limitations and other factors referred
to above and based upon its experience, the Company has estimated its share of
liability to defend and resolve probable asbestos-related personal injury
claims. The Company's estimation of such liability that is probable and
estimable through 2004 ranges from $424.7 million to $813 million. The Company
has concluded that no amount within that range is more likely than any other,
and therefore has reflected $424.7 million as a liability in the accompanying
consolidated financial statements. Of this amount, management expects to incur
approximately $80.0 million in 1999 and has reflected this amount as a current
liability. The Company believes it can reasonably estimate the number and nature
of future claims that may be filed during the next six years. However for claims
that may be filed beyond that period, management believes that the level of
uncertainty is too great to provide for reasonable estimation of the number of
future claims, the nature of such claims, or the cost to resolve them.
Accordingly, it is reasonably possible that the total exposure to personal
injury claims may be greater than the recorded liability. The increase in
recorded liability of $274.2 million in 1998 is primarily reflective of the
increases in claims filed in 1998, recent settlement experience and current
expectations about future claims.

     Because of the uncertainties related to asbestos litigation, it is not
possible to precisely estimate the number of personal injury claims that may
ultimately be filed or their cost. It is reasonably possible there will be
additional claims beyond management's estimates. Management believes that the
potential additional costs for such additional claims, net of any potential
insurance recoveries, will not have a material after-tax effect on the financial
condition of the Company or its liquidity, although the net after-tax effect of
any future liabilities recorded in excess of insurance assets could be material
to earnings in a future period.

     An insurance asset in the amount of $264.8 million is recorded on the
Consolidated Balance Sheet and reflects the Company's belief in the availability
of insurance in this amount, based upon the Company's success in insurance
recoveries, settlement agreements that provide such coverage, the nonproducts
recoveries by other companies, and the opinion of outside counsel. Such
insurance is either available through settlement or probable of recovery through
the ADR process, negotiation or litigation. 

     The Company believes that a claims resolution mechanism alternative to the
Amchem settlement will eventually emerge, but the liability is likely to be
higher than the projection in Amchem.

     Subject to the uncertainties, limitations and other factors referred to
elsewhere in this note and based upon its experience, the Company believes it is
probable that substantially all of the defense and resolution costs of property
damage claims will be covered by insurance.

     Even though uncertainties remain as to the potential number of unasserted
claims and the liability resulting therefrom, and after consideration of the
factors involved, including the ultimate scope of its insurance coverage, the
Wellington Agreement and other settlements with insurance carriers, the results
of the California insurance coverage litigation, the establishment of the
Center, the likelihood that an alternative to the Amchem settlement will
eventually emerge, and its experience, the Company believes the asbestos-related
claims against the Company would not be material either to the financial
condition of the Company or to its liquidity, although the net after-tax effect
of any future liabilities recorded in excess of insurance assets could be
material to earnings in such future period.

b.   The following reports on Form 8-K were filed during the last quarter of
     1998:

     1. On October 21, 1998, the registrant filed a current report on Form 8-K
     announcing its third quarter 1998 results.

     2. On November 2, 1998, the registrant filed a current report on Form 8-K
     announcing that it had completed an underwritten public offering under its
     existing shelf registration statement (File No. 333-6333) of $180 million
     aggregate principal amount of 7.45% Senior Quarterly Interest Bonds due
     2038.

     3. On November 19, 1998, the registrant filed a current report on Form 8-K
     announcing its expectation to take a charge in the fourth quarter of 1998
     of approximately $78 million primarily to reflect a work force reduction.


This 10-K contains certain "forward looking statements" (within the meaning of
the Private Securities Litigation Reform Act of 1995). Among other things, they
pertain to the Company's earnings, liquidity and financial condition; the
ultimate outcome of the Company's asbestos-related litigation (including the
likelihood that an alternative to the Amchem settlement will be negotiated);
anticipated efficiencies relating to acquisitions; and certain operational
matters. Words or phrases denoting the anticipated results of future events -
such as "anticipate," "believe," "estimate," "expect," "will likely," "are
expected to," "will continue," "project," and similar expressions that denote
uncertainty - are intended to identify such forward-looking statements. Actual
results may differ materially from anticipated future results: (1) as a result
of risk and uncertainties identified in connection with those forward-looking
statements, including those factors identified under the sections captioned
"Outlook" in Management's Discussion and Analysis of Financial Condition and
Results of Operations and those factors identified under the caption "Litigation
and Related Matters" in the Notes to Consolidated Financial Statements in
connection with the Company's asbestos-related litigation; (2) as a result of
factors over which the Company has no control, including the strength of
domestic and foreign economies, sales growth, competition and certain costs
increases; or (3) if the factors on which the Company's conclusions are based do
not conform to the Company's expectations.

Period of one month's duration.

          (c) Upon receipt of a Notice of Borrowing, the Administrative Agent
shall promptly notify each Bank of the contents thereof and of such Bank's share
of such Borrowing and such Notice of Borrowing shall not thereafter be revocable

          (d) Not later than 12:00 noon New York City Time on the date of each

          (f) Unless the Administrative Agent shall have received notice from a

to the Administrative Agent such Bank's share of such Borrowing, the
Administrative Agent may assume that such Bank has made such share available to
the Administrative Agent on the date of such Borrowing in accordance with
subsections (d) and (e) of this Section and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Bank shall not have so

Bank fails to do so within three Domestic Business Days of demand therefor, the

amount is repaid to the Administrative Agent, at (i) in the case of the
Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the
interest rate applicable thereto pursuant to Section 2.05 and (ii) in the case

shall not in any manner affect the obligation of the Borrower to repay the Loans
in accordance with the terms of this Agreement.

          (d)  Any Bank may request that Loans made by it be evidenced by a
promissory note.  In such event, the Borrower shall prepare, execute and deliver

shall be repaid in their entirety, on the daily aggregate outstanding principal
amount of the Loans. Accrued fees under this Section shall be payable quarterly
on the last day of each March, June, September and December and upon the date of
termination of the Commitments in their entirety (and, if later, the date the
Loans shall be repaid in their entirety).

          (b)  On the date of this Agreement, the Borrower shall pay to the
Administrative Agent for the account of each Bank an  upfront fee in the amount
heretofore mutually agreed.

          Section 2.07.  Optional Termination or Reduction of Commitments;
Extension of Commitments.  (a)  During the Revolving Credit Period, the Borrower
may, upon at least three Domestic Business Days' notice to the Administrative
Agent, (i) terminate the Commitments at any time, if no Loans are outstanding at
such time or (ii) ratably reduce from time to time by an aggregate amount of
$25,000,000 or any larger multiple of $5,000,000, the aggregate amount of the
Commitments in excess of the aggregate U.S. Dollar Equivalent of the outstanding
principal amount of the Loans.

          (b)  The Borrower may, by notice to the Administrative Agent in a form
approved by the Administrative Agent (which shall promptly deliver a copy to
each of the Banks) not less than 45 days and not more than 60 days prior to the
Termination Date at any time in effect (the "EXISTING TERMINATION DATE"),
request that the Banks extend the Termination Date for an additional 364 days
from the Existing Termination Date.  Each Bank shall, by notice to the Borrower
and the Administrative Agent given not more than 40 and not fewer than 29 days
prior to the Existing Termination Date, advise the Borrower whether or not such
Bank agrees to such extension (and any Bank that does not advise the Borrower on
or before the later of such days shall be deemed to have advised the Borrower
that it will not agree to such extension).

          The Borrower shall have the right, on or before the Existing
Termination Date, to require any Bank which shall have advised or been deemed to
advise the Borrower that it will not agree to an extension of the Termination
Date (each a "NON-EXTENDING BANK") to transfer without recourse (in accordance
with and subject to the restrictions contained in Section 9.06) all its
interests, rights and obligations under this Agreement to one or more other
banks or other financial institutions (any such bank or other financial
institution being called a "SUBSTITUTE BANK"), which may include any Bank;
provided that (i) such Substitute Bank, if not already a Bank hereunder, shall
- --------                                                                      
have been approved by the Administrative Agent (which approval shall not be
unreasonably withheld) and shall execute all such documentation as the
Administrative Agent shall specify to evidence its status as a Bank hereunder,
(ii) such assignment shall become effective as of the Existing Termination Date
and (iii) the Borrower or such Substitute Bank shall pay to such Non-Extending
Bank in immediately available funds on the effective date of such assignment the
principal of and interest accrued to the date of payment on the Loans made by it
hereunder and all other amounts accrued for its account or owed to it hereunder.

          If (and only if) Banks (including Substitute Banks) holding
Commitments that represent at least 60% of the Total Commitment on the 45th day
prior to the Existing Termination Date shall have agreed, on or before the
Existing Termination Date, to extend the Existing Termination Date (the
"CONTINUING BANKS"), then the Termination Date shall be extended to the date 364
days after the Existing Termination Date (provided, that if such date is not a
                                          --------                            
Eurocurrency Business Day, then the Termination Date shall be extended to the
next 

                                       14

preceding Eurocurrency Business Day). The decision to agree or withhold
agreement to any extension of the Termination Date hereunder shall be at the
sole discretion of each Bank. The Commitment of each Non-Extending Bank (after
giving effect to each transfer and assignment pursuant to this paragraph (b))
shall terminate, and all Loans of such Non-Extending Bank shall become due and
payable, together with all interest accrued thereon and all other amounts owed
to such Bank hereunder, on the Existing Termination Date.

          Notwithstanding the foregoing, no extension of the Termination Date
shall be effective with respect to any Bank unless, on and as of the Existing
Termination Date, the conditions set forth in paragraphs (b) and (c) of Section
3.02 shall be satisfied and the Administrative Agent shall have received a
certificate to that effect, dated the Existing Termination Date and executed by
a Senior Executive Officer of the Borrower.

          Section 2.08.  Mandatory Termination and Reduction of Commitments.
The Commitments shall terminate on the Termination Date, and any Loans then
outstanding (together with accrued interest thereon) shall be due and payable on
such date.

          Section 2.09.  Optional Payments.  (a)  Subject in the case of any
Eurocurrency Borrowing to Section 2.11, the Borrower may, upon at least one
Domestic Business Day's notice to the Administrative Agent, prepay any Base Rate
Borrowing, or upon at least three Eurocurrency Business Days' notice to the
Administrative Agent, prepay any Eurocurrency Borrowing, in each case in whole
at any time, or from time to time in part in amounts that are multiples of the
Borrowing Multiple and at least equal to the Borrowing Minimum by paying the
principal amount to be prepaid together with accrued interest thereon to the
date of prepayment.  Each such optional prepayment shall be applied to prepay
ratably the Loans of the several Banks included in such Borrowing.

          (b)  Upon receipt of a notice of prepayment pursuant to this Section,
the Administrative Agent shall promptly notify each Bank of the contents thereof
and of such Bank's ratable share (if any) of such prepayment and such notice
shall not thereafter be revocable by the Borrower.

          Section 2.10.  General Provisions as to Payments. (a)  The Borrower
shall make each payment of principal of, and interest on, the Loans and of fees
hereunder, without setoff, counterclaim or other deduction, not later than 12:00
Noon New York City Time on the date when due, in U.S. Dollars or the applicable
Designated Currency, as the case may be, in immediately available funds to such
account as the Administrative Agent shall specify.  All payments due under this
Agreement other than the payments of the principal of and interest on Loans
denominated in Foreign Currencies shall be made in U.S. Dollars.  The
Administrative Agent will promptly distribute to each Bank its ratable share of
each such payment received by the Administrative Agent for the account of the
Banks.  Whenever any payment of principal of, or interest on, Base Rate Loans or
of fees shall be due on a day which is not a Domestic Business Day, the date for
payment thereof shall be extended to the next succeeding Domestic Business Day.
Whenever any payment of principal of, or interest on, the Eurocurrency Loans
shall be due on a day which is not a Eurocurrency Business Day, the date for
payment thereof shall be extended to the next succeeding Eurocurrency Business
Day unless such Eurocurrency Business Day falls in another calendar month, in
which case the date for payment thereof shall be the next preceding Eurocurrency
Business Day.  If the date for any payment of principal is extended by operation
of law or otherwise, interest thereon shall be payable for such extended time.

                                       15
<PAGE>
 
          (b)  Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Banks
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank.  If and to the extent
that the Borrower shall not have so made such payment, each Bank shall repay to
the Administrative Agent forthwith on demand such amount distributed to such
Bank together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Administrative Agent, at the Federal Funds Rate.

          Section 2.11.  Funding Losses.  If (i) the Borrower makes any payment
of principal with respect to any Eurocurrency Loan (pursuant to Article 2, 6, or
8 or otherwise), (ii) any Non-Increasing Bank receives a payment of principal
pursuant to Section 2.13(b) or (iii) any Non-Extending Bank receives a payment
of principal pursuant to Section 2.07(b) on any day other than the last day of
the Interest Period applicable thereto, or the last day of an applicable period
fixed pursuant to Section 2.05(d), or if the Borrower fails to borrow or prepay
any Eurocurrency Loan after notice has been given to any Bank in accordance with
Section 2.02(c) or 2.09(b), the Borrower shall reimburse each Bank within 15
days after demand for any resulting loss or reasonable expense incurred by it
(or by an existing Participant in the related Loan), including (without
limitation) any loss incurred in obtaining, liquidating or employing deposits
from third parties, but excluding loss of margin, for the period after any such
payment or failure to borrow or prepay, provided that such Bank shall have
                                        --------                          
delivered to the Borrower a certificate as to the amount of such loss or
expense, which certificate shall be conclusive in the absence of manifest error.

          Section 2.12.  Computation of Interest and Fees.  Interest based on
the Prime Rate hereunder shall be computed on the basis of a year of 365 days
(or 366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day).  Interest based on the
Federal Funds Rate or the Adjusted London Interbank Offered Rate shall be
computed on the basis of a year of 360 days, and paid for the actual number of
days elapsed (including the first day but excluding the last day).  Fees shall
be computed on the basis of a year of 360 days and paid for the actual number of
days elapsed (including the first day but excluding the last day).

          Section 2.13.  Increase in Commitments.  (a)  The Borrower may, by
written notice to the Administrative Agent (which shall promptly deliver a copy
to each of the Banks), request that the total Commitments be increased by an
amount not less than $25,000,000 for any such increase and not greater than
$250,000,000 minus the aggregate amount of prior or simultaneous increases of
the Commitments under this Agreement and the Multi-Year Agreement.  Such notice
shall set forth the amount of the requested increase in the total Commitments
and the date on which such increase is requested to become effective (which
shall be not less than 45 days or more than 60 days after the date of such
notice), and shall offer each Bank the opportunity to increase its Commitment by
its Applicable Percentage of the proposed increased amount.  Each Bank shall, by
notice to the Borrower and the Administrative Agent given not more than 20 days
after the date of the Borrower's notice, either agree to increase its Commitment
by all or a portion of the offered amount (each Bank so agreeing being an
"INCREASING BANK") or decline to increase its Commitment (and any Bank that does
not deliver such a notice within such period of 20 days shall be deemed to have
declined to increase its Commitment) (each Bank so declining or deemed to have
declined being a "NON-INCREASING BANK").  In the event that, on the 20th day
after the Borrower shall have 

                                       16
<PAGE>
 
delivered a notice pursuant to the first sentence of this paragraph, the Banks
shall have agreed pursuant to the preceding sentence to increase their
Commitments by an aggregate amount less than the increase in the total
Commitments requested by the Borrower, the Borrower may arrange for one or more
banks or other financial institutions (any such bank or other financial
institution referred to in this paragraph (a) being called an "AUGMENTING
BANK"), which may include any Bank, to extend Commitments or increase its
existing Commitments in an aggregate amount equal to the unsubscribed amount;
provided that each Augmenting Bank, if not already a Bank hereunder, shall be
- --------
subject to the approval of the Administrative Agent (which approval shall not be
unreasonably withheld) and each Augmenting Bank shall execute all such
documentation as the Administrative Agent shall specify to evidence its
Commitment and its status as a Bank hereunder. Increases and new Commitments
created pursuant to this paragraph (a) shall become effective on the date
specified in the notice delivered by the Borrower pursuant to the first sentence
of this paragraph. Notwithstanding the foregoing, no increase in the total
Commitments (or in the Commitment of any Bank) shall become effective under this
paragraph unless, (i) on the date of such increase, the conditions set forth in
paragraphs (b) and (c) of Section 3.02 shall be satisfied and the Administrative
Agent shall have received a certificate to that effect dated such date and
executed by a Financial Officer of the Borrower, and (ii) the Administrative
Agent shall have received (with sufficient copies for each of the Banks)
documents consistent with those delivered under clauses (b) and (c) of Section
3.01 as to the corporate power and authority of the Borrower to borrow hereunder
and as to the enforceability of this Agreement after giving effect to such
increase.

          (b)  On the effective date (the "INCREASE EFFECTIVE DATE") of any
increase in the total Commitments pursuant to paragraph (a) above (the
"COMMITMENT INCREASE"), (i) the aggregate principal amount of the Loans
outstanding (the "INITIAL LOANS") immediately prior to giving effect to the
Commitment Increase on the Increase Effective Date shall be deemed to be paid,
(ii) each Increasing Bank and each Augmenting Bank that shall have been a Bank
prior to the Commitment Increase shall pay to the Administrative Agent in same
day funds an amount equal to the difference between (A) the product of (1) such
Bank's Applicable Percentage (calculated after giving effect to the Commitment
Increase) multiplied by (2) the amount of the Subsequent Borrowings (as
hereinafter defined) and (B) the product of (1) such Bank's Applicable
Percentage (calculated without giving effect to the Commitment Increase)
multiplied by (2) the amount of the Initial Loans, (iii) each Augmenting Bank
that shall not have been a Bank prior to the Commitment Increase shall pay to
Administrative Agent in same day funds an amount equal to the product of (1)
such Augmenting Bank's Applicable Percentage (calculated after giving effect to
the Commitment Increase) multiplied by (2) the amount of the Subsequent
Borrowings, (iv) after the Administrative Agent receives the funds specified in
clauses (ii) and (iii) above, the Administrative Agent shall pay to each Non-
Increasing Bank the portion of such funds that is equal to the difference
between (A) the product of (1) such Non-Increasing Bank's Applicable Percentage
(calculated without giving effect to the Commitment Increase) multiplied by (2)
the amount of the Initial Loans, and (B) the product of (1) such Non-Increasing
Bank's Applicable Percentage (calculated after giving effect to the Commitment
Increase) multiplied by (2) the amount of the Subsequent Borrowings (v) after
the effectiveness of the Commitment Increase, the Borrower shall be deemed to
have made new Borrowings (the "SUBSEQUENT BORROWINGS") in an aggregate principal
amount equal to the aggregate principal amount of the Initial Loans in the
currency or currencies, and of the types and for the Interest Periods specified
in a Notice of Borrowing delivered to the Administrative Agent in accordance
with Section 2.02, (vi) each Non-Increasing Bank, each Increasing Bank and each
Augmenting Bank shall be deemed to hold its Applicable Percentage of each
Subsequent Borrowing (calculated after giving effect to the Commitment Increase)
and 

                                       17
<PAGE>
 
(vii) the Borrower shall pay each Increasing Bank and each Non-Increasing
Bank any and all accrued but unpaid interest on the Initial Loans.

constitute a default under, any provision of applicable law or regulation or of
the articles of incorporation or by-laws of the Borrower or of any material
agreement, judgment, injunction, order, decree or other instrument binding upon
the Borrower or any of its Subsidiaries or result in the creation or imposition
of any Lien on any asset of the Borrower or any of its Subsidiaries.

          Section 4.03.  Binding Effect.  This Agreement constitutes a valid and
binding agreement of the Borrower, enforceable in accordance with its terms and
each note, when executed and delivered in accordance with this Agreement, will
constitute a valid and binding obligation of the Borrower, in each case
enforceable in accordance with its terms.

          Section 4.04.  Financial Information.  (a)  The consolidated balance
sheet of the Borrower and its Consolidated Subsidiaries as of December 31, 1997
and the related consolidated statements of earnings and cash flows for the
fiscal year then ended, reported on by independent public accountants and set

each of the Banks, fairly present, in conformity with generally accepted
accounting principles, the consolidated financial position of the Borrower and
its Consolidated Subsidiaries as of such date and their consolidated results of
operations and cash flows for such fiscal year.

<PAGE>
 
          Section 4.05.  Litigation.  Except as disclosed in the Borrower's 1997
Form 10-K, in the Borrower's Latest Form 10-Q or as may hereafter be disclosed
in writing by the Borrower to the Banks or in reports filed with the Securities
and Exchange Commission, there is no action, suit or proceeding pending against,
or to the knowledge of the Borrower threatened against or affecting, the
Borrower or any of its Subsidiaries before any court or arbitrator or any
governmental body, agency or official in which there is a reasonable possibility
of an adverse decision which could materially adversely affect the business,
financial position, operations or prospects of the Borrower and its Consolidated
Subsidiaries, considered as a whole, or the ability of the Borrower to perform
its obligations under this Agreement.  There is no action, suit or proceeding
pending against, or the knowledge of the Borrower threatened against or

business, the Borrower reviews the effect of Environmental Laws on the business,
operations and properties of the Borrower and its Subsidiaries, in the course of
which it identifies and evaluates associated liabilities and costs.  On the
basis of this review, the Borrower has reasonably concluded that, to the best of
its knowledge, except as disclosed in reports filed with the Securities and
Exchange Commission, copies of which reports have been delivered to the Banks,
such associated liabilities and costs, including the costs of compliance with
Environmental Laws, are unlikely to have a material adverse effect on the
business, financial condition, results of operations or prospects of the
Borrower and its Consolidated Subsidiaries, considered as a whole.

          Section 4.07.  Taxes.  The Borrower and its Subsidiaries have filed
all United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes due pursuant to
such returns or pursuant to any assessment received by the Borrower or any
Subsidiary.  The charges, accruals and reserves on the books of the Borrower and
its Subsidiaries in respect of taxes or other governmental charges are, in the
opinion of the Borrower, adequate.

          Section 4.08.  Significant Subsidiaries.  Each of the Borrower's
Significant Subsidiaries is a corporation duly incorporated, validly existing
and in good standing under the laws of its jurisdiction of incorporation, and
has all corporate powers and all material governmental licenses, authorizations,
consents and approvals required to carry on its business as now conducted.

          Section 4.09.  Not an Investment Company.  The Borrower is not an
"Investment Company" within the meaning of the Investment Company Act of 1940,
as amended.

date as of which such information is stated or certified.  The Borrower has
disclosed to the Banks in writing or in reports filed with the Securities and
Exchange Commission, copies of which reports have been delivered to the Banks,
any and all facts which materially and adversely affect or may affect (to the
extent the Borrower can now reasonably foresee) the business, operations or
financial condition of the Borrower and its Consolidated Subsidiaries, taken as
a whole, or the ability of the Borrower to perform its obligations under this
Agreement.

     in the case of such statements of income and cash flows in comparative form
     the figures for the corresponding quarter and the corresponding portion of
     the Borrower's previous fiscal year, all certified (subject to normal year-

     accounting principles and consistency by the chief financial officer or the
     chief accounting officer of the Borrower;

     5.07 and 5.08 on the date of such financial statements and (ii) stating
     whether any Default exists on the date of such certificate and, if any
     Default then exists, setting forth the details thereof and the action which
     the Borrower is taking or proposes to take with respect thereto;

whole, shall mean 20% or more of the consolidated assets of the Borrower and its

     the Borrower or any Significant Subsidiary seeking liquidation,
     reorganization or other relief with respect to it or its debts under any
     bankruptcy, insolvency or other similar law now or hereafter in effect or

     which the PBGC would be entitled to obtain a decree adjudicating that any
     Material Plan must be terminated; or (E) there shall occur a complete or
     partial withdrawal from, or a default, within the meaning of Section

appoints and authorizes the Administrative Agent to take such action as
Administrative Agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof or
thereof, together with all such powers as are reasonably incidental thereto.

          Section 7.02.  Administrative Agent and Affiliates.  The Chase
Manhattan Bank of New York shall have the same rights and powers under this
Agreement as any other Bank and may exercise or refrain from exercising the same
as though it were not the Administrative Agent, and The Chase Manhattan Bank and
its affiliates may accept deposits from, lend money to, and generally engage in
any kind of business with the Borrower or any Subsidiary or affiliate of the
Borrower as if it were not the Administrative Agent hereunder.

          Section 7.03.  Action by Administrative Agent.  The obligations of the
Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action with respect to any Default, except as
expressly provided in Article 6.

          Section 7.04.  Consultation with Experts.  The Administrative Agent
may consult with legal counsel (who may be counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

          Section 7.05.  Liability of Administrative Agent. Neither the
Administrative Agent nor any of its affiliates nor any of their respective
directors, officers, agents or employees shall be liable for any action taken or

<PAGE>
 
or at the request of the Required Banks or (ii) in the absence of its own gross
negligence or willful misconduct. Neither the Administrative Agent nor any of
its affiliates nor any of their respective directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with
this Agreement or any borrowing hereunder; (ii) the performance or observance of
any of the covenants or agreements of the Borrower; (iii) the satisfaction of
any condition specified in Article 3, except receipt of items required to be
delivered to the Administrative Agent; or (iv) the validity, effectiveness or
genuineness of this Agreement or any other instrument or writing furnished in
connection herewith. The Administrative Agent shall not incur any liability by
acting in reliance upon any notice, consent, certificate, statement, or other
writing (which may be a bank wire, telex, facsimile transmission or similar
writing) believed by it to be genuine or to be signed by the proper party or
parties.

          Section 7.06.  Indemnification.  Each Bank shall, ratably in
accordance with its Commitment, indemnify the Administrative Agent, its
affiliates and their respective directors, officers, agents and employees (to
the extent not reimbursed by the Borrower) against any cost, expense (including
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from such indemnitees' gross negligence or willful
misconduct) that such indemnitees may suffer or incur in connection with this
Agreement or any action taken or omitted by such indemnitees hereunder.

          Section 7.07.  Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon any Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also

any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

          Section 7.08.  Successor Administrative Agent.  The Administrative
Agent may resign at any time by giving notice thereof to the Banks and the
Borrower.  Upon any such resignation, the Borrower shall have the right to
appoint a successor Administrative Agent, subject to the approval of the
Required Banks.  If no successor Administrative Agent shall have been so
appointed and approved, and shall have accepted such appointment, within 45 days
after the retiring Administrative Agent gives notice of resignation, then the
retiring Administrative Agent may, on behalf of the Banks, appoint a successor
Administrative Agent, which shall be a commercial bank organized or licensed
under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $50,000,000.  Upon the
acceptance of its appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder.  After any retiring Administrative
Agent's resignation hereunder as Administrative Agent, the provisions of this
Article shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent.

                            Change in Circumstances

          Section 8.01.  Basis for Determining Interest Rate Inadequate.  If on
or prior to the first day of any Interest Period for any Eurocurrency Borrowing,
the Administrative Agent is advised by the Required Banks that deposits in
Dollars (in the applicable amounts) are not being offered to the Required Banks
in the relevant market for such Interest Period, the Administrative Agent shall
forthwith give notice thereof to the Borrower and the Banks, whereupon until the
Administrative Agent notifies the Borrower that the circumstances giving rise to
such suspension no longer exist, the obligations of the Banks to make
Eurocurrency Loans shall be suspended. Unless the Borrower notifies the
Administrative Agent at least two Domestic Business Days before the date of any
Eurocurrency Borrowing for which a Notice of Borrowing has previously been given
that it elects not to borrow such Borrowing on such date, such Borrowing shall
instead be made as a Base Rate Borrowing.

          Section 8.02.  Illegality.  If, on or after the date of this
Agreement, the adoption of any applicable law, rule or regulation, or any change
in any applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Eurocurrency Lending Office) with any formal
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for any Bank (or its Eurocurrency Lending Office) to make, maintain
or fund its Dollar-Denominated Eurocurrency Loans or Eurocurrency Loans
denominated in a Designated Currency, as the case may be, and such Bank shall so
notify the Administrative Agent, the Administrative Agent shall forthwith give
notice thereof to the other Banks and the Borrower, whereupon until such Bank
notifies the Borrower and the Administrative Agent that the circumstances giving
rise to such suspension no longer exist, the obligation of such Bank to make
Dollar-denominated Eurocurrency Loans or Eurocurrency Loans denominated in a
Designated Currency shall be suspended.  Before giving any notice to the
Administrative Agent pursuant to this Section, such Bank shall designate a
different Eurocurrency Lending Office if such designation will avoid the need
for giving such notice and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank.  If such Bank shall determine that it may not
lawfully continue to maintain and fund any of its outstanding Dollar-denominated
Eurocurrency Loans or Eurocurrency Loans denominated in a Designated Currency to
maturity and shall so specify in such notice, the Borrower shall immediately
prepay in full the then outstanding principal amount of each such Eurocurrency
Loan, together with accrued interest thereon.  Concurrently with prepaying each
such Eurocurrency Loan, the Borrower shall borrow a Base Rate Loan in an equal
principal amount (or, in the case of a Eurocurrency Loan in a Designated
Currency, a Dollar amount equal to such amount based on the current Exchange
Rate) from such Bank (on which interest and principal shall be payable
contemporaneously with the related Eurocurrency Loans of the other Banks), and
such Bank shall make such a Base Rate Loan.

          Section 8.03.  Increased Cost and Reduced Return.  (a)  If on or after
the date hereof, the adoption of any applicable law, rule or regulation, or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) with any
formal request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall impose, modify or deem
applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System, but excluding
with respect to any Eurocurrency Loan any such requirement included in an
applicable Eurocurrency Reserve Percentage), special deposit, insurance
assessment or similar requirement against assets of, deposits with or for the
account of, or credit extended by, any Bank (or its Applicable Lending Office)
or shall impose on any Bank (or its Applicable Lending Office) or on the London
interbank market any other condition affecting its Eurocurrency Loans or its
obligation to make Eurocurrency Loans and the result of any of the foregoing is
to increase the cost to such Bank (or its Applicable Lending Office) of making
or maintaining any Eurocurrency Loan, or to reduce the amount of any sum
received or receivable by such Bank (or its Applicable Lending Office) under
this Agreement by an amount deemed by such Bank to be material, then, within 15
days after demand by such Bank (with a copy to the Administrative  Agent), the
Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank for such increased cost or reduction.

          (b) If any Bank shall have determined that, after the date hereof, the
adoption of any applicable law, rule or regulation regarding capital adequacy,
or any change in any such law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or any formal request or directive regarding capital adequacy (whether
or not having the force of law) of any such authority, central bank or
comparable agency (including any determination by any such authority, central
bank or comparable agency that, for purposes of capital adequacy requirements,
the Commitments hereunder do not constitute commitments with an original
maturity of one year or less), has or would have the effect of reducing the rate
of return on capital of such Bank (or its Parent) as a consequence of such
Bank's obligations hereunder to a level below that which such Bank (or its
Parent) could have achieved but for such adoption, change, request or directive
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, within 15
days after demand by such Bank (with a copy to the Administrative Agent), the
Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank (or its Parent) for such reduction.

          (c)  Each Bank will promptly notify the Borrower and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Bank to compensation pursuant to this
Section and will designate a different Applicable Lending Office if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the judgment of such Bank, be otherwise disadvantageous to such
Bank.  A certificate of any Bank claiming compensation under this Section and
setting forth the additional amount or amounts to be paid to it hereunder shall
be conclusive in the absence of manifest error.  In determining such amount,
such Bank may use any reasonable averaging and attribution methods.

          Section 8.04.  (a)  Taxes.  For purposes of this Section 8.04, the
following terms have the following meanings:

                                       29
<PAGE>
 
          "TAXES" means any and all present or future taxes, duties, levies,
     imposts, deductions, charges or withholdings with respect to any payment by
     the Borrower pursuant to this Agreement and all liabilities with respect
     thereto, excluding (i) in the case of each Bank and the Administrative
     Agent, taxes imposed on its income, and franchise or similar taxes imposed
     on it, by a jurisdiction under the laws of which such Bank or the
     Administrative Agent (as the case may be) is organized or in which its
     principal executive office is located or, in the case of each Bank, in
     which its Applicable Lending Office is located and (ii) in the case of each
     Bank, any United States withholding tax imposed on such payments but only
     to the extent that such Bank is subject to United States withholding tax at
     the time such Bank first becomes a party to this Agreement.

          "OTHER TAXES" means any present or future stamp or documentary taxes
     and any other excise or property taxes, or similar charges or levies, which
     arise from any payment made pursuant to this Agreement or from the
     execution or delivery of, or otherwise with respect to, this Agreement.

          (b)  Any and all payments by the Borrower to or for the account of any
Bank or the Administrative Agent hereunder shall be made without deduction for
any Taxes or Other Taxes; provided that, if the Borrower shall be required by
                          --------                                           
law to deduct any Taxes or Other Taxes from any such payments, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 8.04) such Bank or the Administrative Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Administrative Agent, at its address referred to in Section 9.01,
the original or a certified copy of a receipt evidencing payment thereof.

          (c)  The Borrower agrees to indemnify each Bank and the Administrative
Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section 8.04) paid by such Bank or the Administrative
Agent (as the case may be) and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto.  This indemnification shall
be paid within 15 days after such Bank or the Administrative Agent (as the case
may be) makes demand therefor.

          (d)  (i) With respect to any payment by the Borrower (or a Subsidiary)
from the United States, each Bank organized under the laws of a jurisdiction
outside the United States, on or prior to the date of its execution and delivery
of this Agreement in the case of each Bank listed on the signature pages hereof
and on or prior to the date on which it becomes a Bank in the case of each other
Bank, and from time to time thereafter if requested in writing by the Borrower
(but only so long as such Bank remains lawfully able to do so), shall provide
the Borrower with Internal Revenue Service Form 1001 or 4224, as appropriate, or
any successor form prescribed by the Internal Revenue Service, certifying that
such Bank is entitled to benefits under an income tax treaty to which the United
States is a party which exempts the Bank from United States withholding tax or
reduces the rate of withholding tax on payments of interest for the account of
such Bank or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States; provided that such Bank shall not be required to deliver any form
        --------                                                         
pursuant to this Section 8.05(d)(i) that such Bank is not legally able to
deliver.

                                       30
<PAGE>
 
          (ii) With respect to any payment by the Borrower (or a Subsidiary)
from a jurisdiction other than the United States, each Bank organized under the
laws of a jurisdiction other than the jurisdiction from which payment is made
("RELEVANT JURISDICTION") that is entitled to an exemption from or reduction of
withholding tax under the law of the Relevant Jurisdiction, or any treaty to
which such Relevant Jurisdiction is a party, with respect to payments under this
Agreement shall, after having received written notice from the Borrower (or the
applicable Subsidiary) advising it of the availability of such exemption or
reduction and containing all relevant documentation, deliver to the Borrower (or
the applicable Subsidiary), with a copy to the Administrative Agent, at the time
or times prescribed by the applicable law, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Borrower (or the applicable Subsidiary) as will permit such payments to be made
without withholding at a reduced rate.

          (e)  For any period with respect to which a Bank has failed to provide
the Borrower with the appropriate form pursuant to Section 8.04(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which such form originally was required to be provided), such Bank
shall not be entitled to indemnification under Section 8.04(b) or 8.04(c) with
respect to Taxes imposed by the Relevant Jurisdiction or the United States, as
the case may be; provided that if a Bank, which is otherwise exempt from or
                 --------                                                  
subject to a reduced rate of withholding tax, becomes subject to Taxes because
of its failure to deliver a form required hereunder, the Borrower shall take
such steps as such Bank shall reasonably request to assist such Bank to recover
such Taxes.

          (f)  If the Borrower is required to pay additional amounts to or for
the account of any Bank pursuant to this Section 8.04, then such Bank will
change the jurisdiction of its Applicable Lending Office if, in the judgment of
such Bank, such change (i) will eliminate or reduce any such additional payment
which may thereafter accrue and (ii) is not otherwise disadvantageous to such
Bank.

          Section 8.05.  Base Rate Loans Substituted for Affected Eurocurrency
Loans.  If (i) the obligation of any Bank to make Eurocurrency Loans has been
suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation
under Section 8.03 or 8.04 with respect to its Eurocurrency Loans and the
Borrower shall, by at least five Eurocurrency Business Days' prior notice to
such Bank through the Administrative Agent, have elected that the provisions of
this Section shall apply to such Bank, then, unless and until such Bank notifies
the Borrower that the circumstances giving rise to such suspension or demand for
compensation no longer exist:

          (a) all Loans which would otherwise be made by such Bank as
     Eurocurrency Loans, shall be made instead as Base Rate Loans (on which
     interest and principal shall be payable contemporaneously with the related
     Eurocurrency Loans of the other Banks), and

          (b) after each of its Eurocurrency Loans has been repaid, all payments
     of principal which would otherwise be applied to repay such Eurocurrency
     Loans shall be applied to repay its Base Rate Loans instead.

          Section 8.06.  Substitution of Bank.  If (i) the obligation of any
Bank to make Eurocurrency Loans has been suspended pursuant to Section 8.02 or
(ii) any Bank has demanded compensation under Section 8.03 or 8.04, the Borrower
shall have the right, with the assistance of the Administrative

                                       31
<PAGE>
 
Agent, to seek a mutually satisfactory substitute bank or banks (which may be
one or more of the Banks) to assume the Commitment of such Bank.

         --------                                                            
Article 8 shall not be effective until received.

          Section 9.02.  No Waivers.  No failure or delay by the Administrative
Agent or any Bank in exercising any right, power or privilege hereunder shall
operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege.  The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

          Section 9.03.  Expenses; Indemnification.  (a)  The Borrower shall pay
(i) all reasonable out-of-pocket expenses of the Administrative Agent, including
fees and disbursements of special counsel for the Administrative Agent, in
connection with the preparation and administration of this Agreement, any waiver
or consent hereunder or any amendment hereof or any Default or alleged Default
hereunder and (ii) if an Event of Default occurs, all reasonable out-of-pocket
expenses incurred by the Administrative Agent and each Bank, including (without
duplication) the fees and  disbursements of outside counsel and the allocated
cost of inside counsel, in connection with such Event of Default and collection,
bankruptcy, insolvency and other enforcement proceedings resulting therefrom.

          (b)  The Borrower agrees to indemnify the Administrative Agent and
each Bank, their respective affiliates and the respective directors, officers,
agents and employees of the foregoing (each an "INDEMNITEE") and hold each
Indemnitee harmless from and against any and all liabilities, losses, damages,
reasonable costs and expenses of any kind, including, without limitation, the
reasonable fees and disbursements of counsel, which may be incurred by such
Indemnitee in connection with any investigative, administrative or judicial
proceeding (whether or not such Indemnitee shall be designated a party thereto)
brought or threatened relating to or arising out of this Agreement or any actual
or proposed use of proceeds of Loans hereunder; provided that (i) no Indemnitee
                                                --------                       
shall have the right to be indemnified hereunder for such Indemnitee's own gross
negligence or willful misconduct as determined by a court of competent
jurisdiction, (ii) in the case of an investigation or a proceeding to which an
Indemnitee is not a party, such Indemnitee shall be entitled to indemnification
only if such Indemnitee is required to respond to process or other formal
inquiry in connection therewith and (iii) any claim for 

                                       32
<PAGE>
 
indemnification hereunder shall be made not later than three years after the
termination of the Commitments and repayment in full of the Loans.

          Section 9.04.  Sharing of Set-Offs.  The Banks agree among themselves
that if any Bank shall, by exercising any right of set-off or counterclaim or
otherwise, receive payment of a proportion of the aggregate amount of principal
and interest due with respect to any Loan made by it which is greater than the
proportion received by any other Bank in respect of the aggregate amount of
principal and interest due with respect to any Loan made by such other Bank, the
Bank receiving such proportionately greater payment shall purchase such
participations in the Loans made by the other Banks, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Loans made by the Banks shall be shared by the
Banks pro rata; provided that nothing in this Section shall impair the right of
                --------                                                       
any Bank to exercise any right of set-off or counterclaim it may have and to
apply the amount subject to such exercise to the payment of indebtedness of the
Borrower other than its indebtedness hereunder.

          Section 9.05.  Amendments and Waivers.  Any provision of this
Agreement may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by the Borrower and the Required Banks (and, if the
rights or duties of the Administrative Agent are affected thereby, by the
Administrative Agent); provided that no such amendment or waiver shall, unless
                       --------                                               
signed by all the Banks, (i) increase or decrease the Commitment of any Bank
(except for a ratable decrease in the Commitments of all Banks) or subject any
Bank to any additional obligation, (ii) reduce the principal of or rate of
interest on any Loan or any fees hereunder, (iii) postpone the date fixed for
any payment of principal of or interest on any Loan or any fees hereunder or for
termination of any Commitment or (iv) change the percentage of the Commitments
or of the aggregate unpaid principal amount of the Loans, or the number of
Banks, which shall be required for the Banks or any of them to take any action
under this Section or any other provision of this Agreement.

          Section 9.06.  Successors and Assigns.  (a)  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

          (b)  Any Bank may at any time grant to one or more banks or other
institutions (each a "PARTICIPANT") participating interests in its Commitment or
any or all of its Loans.  In the event of any such grant by a Bank of a
participating interest to a Participant, such Bank shall remain responsible for
the performance of its Commitment and its other obligations hereunder, and the
Borrower and the Administrative Agent shall continue to deal solely and directly
with such Bank in connection with such Bank's rights and obligations under this
Agreement.  Any agreement pursuant to which any Bank may grant such a
participating interest shall provide that such Bank shall retain the sole right
and responsibility to enforce the obligations of the Borrower hereunder
including, without limitation, the right to approve any amendment, modification
or waiver of any provision of this Agreement; provided that such participation
                                              --------                        
agreement may provide that such Bank will not agree to any modification,
amendment or waiver of this Agreement described in clause (i), (ii), (iii) or
(iv) of Section 9.05 without the consent of the Participant.  The Borrower
agrees that each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of Article with respect to its
participating interest.  An assignment or other transfer which is not permitted
by subsection (c) or (d) below shall be given effect for purposes of this
Agreement only to the extent of a participating interest granted in accordance
with this subsection (b).

                                       33
<PAGE>
 
          (c)  Any Bank may at any time assign to one or more banks or other
institutions (each an "ASSIGNEE") all, or a proportionate part of all, of its
rights and obligations under this Agreement, and such Assignee shall assume such
rights and obligations, pursuant to an Assignment and Assumption Agreement in
substantially the form of Exhibit D hereto executed by such Assignee and such
transferor Bank, with (and subject to) the subscribed consent of the Borrower
and the Administrative Agent, which consents will not be unreasonably withheld;
provided that (i) if an Assignee is a Bank prior to giving effect to such
- --------                                                                 
assignment or is an affiliate of such transferor Bank, no such consent shall be
required and (ii) if at the time of such assignment an Event of Default shall
have occurred and be continuing, no such consent of the Borrower shall be
required.  Upon execution and delivery of such instrument and payment by such
Assignee to such transferor Bank of an amount equal to the purchase price agreed
between such transferor Bank and such Assignee, such Assignee shall be a Bank
party to this Agreement and shall have all the rights and obligations of a Bank
with a Commitment as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required.  In connection with any such assignment, the transferor Bank shall pay
to the Administrative Agent an administrative fee for processing such assignment
in the amount of $2,500.  If the Assignee is not incorporated under the laws of
the United States of America or a state thereof, it shall deliver to the
Borrower and the Administrative Agent certification as to exemption from
deduction or withholding of any United States federal income taxes in accordance
with Section 8.04.

          (d)  Any Bank may at any time assign all or any portion of its rights
under this Agreement to a Federal Reserve Bank.  No such assignment shall
release the transferor Bank from its obligations hereunder.

          (e)  No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.02, 8.03 or requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

          Section 9.07.  Collateral.  Each of the Banks represents to each Agent
and each of the other Banks that it in good faith is not relying upon any Margin
Stock as collateral in the extension or maintenance of the credit provided for
in this Agreement.

          Section 9.08  Governing Law; Submission to Jurisdiction.  This
Agreement shall be governed by and construed in accordance with the laws of the
State of New York.  The Borrower hereby submits to the nonexclusive jurisdiction
of the United States District Court for the Southern District of New York and of
any New York State court sitting in New York City for purposes of all legal
proceedings arising out of or relating to this Agreement or the transactions
contemplated hereby.  The Borrower irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of the venue of any such proceeding brought in such a court and any claim that
any such proceeding brought in such a court has been brought in an inconvenient
forum.

          Section 9.09.  Counterparts; Integration.  This Agreement may be
signed in any number of counterparts, each of which shall be an original, with
the same effect as if the signatures thereto and hereto were upon the same
instrument.  This Agreement constitutes the 

                                       34
<PAGE>
 
entire agreement and understanding among the parties hereto and supersedes any
and all prior agreements and understandings, oral or written, relating to the
subject matter hereof.

          SECTION 9.10.  WAIVER OF JURY TRIAL.  EACH OF THE BORROWER, THE
ADMINISTRATIVE AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT
TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          Section 9.11.  Conversion of Currencies.  (a)  If, for the purpose of
obtaining judgment in any court, it is necessary to convert a sum owing
hereunder in one currency into another currency, each party hereto agrees, to
the fullest extent that it may lawfully do so, that the rate of exchange used
shall be that at which in accordance with normal banking procedures in the
relevant jurisdiction the first currency could be purchased with such other
currency on the Domestic Business Day (or Eurocurrency Business Day if
applicable) immediately preceding the day on which final judgment is given.

          (b)  The obligations of each party hereto in respect of any sum due to
any other party hereto or any holder of the obligations owing hereunder (the
"APPLICABLE CREDITOR") shall, notwithstanding any judgment in a currency (the
"JUDGMENT CURRENCY") other than the currency in which such sum is stated to be
due hereunder (the "AGREEMENT CURRENCY"), be discharged only to the extent that,
on the Business Day following receipt by the Applicable Creditor of any sum
adjudged to be so due in the Judgment Currency, the Applicable Creditor may in
accordance with normal banking procedures in the relevant jurisdiction purchase
the Agreement Currency with the Judgment Currency; if the amount of the
Agreement Currency so purchased is less than the sum originally due to the
Applicable Creditor in the Agreement Currency, such party agrees, as a separate
obligation and notwithstanding any such judgment, to indemnify the Applicable
Creditor against such loss.  The obligations of the parties contained in this
Section 9.11 shall survive the termination of this Agreement and the payment of
all other amounts owing hereunder.

          Section 9.12. European Economic and Monetary Union. (a) Definitions.

"Business Day" shall be construed as a reference to a day (other than a Saturday
or Sunday) on which banks are generally open for business in

          (i)  London and New York City and

          (ii) Frankfurt am Main, Germany (or such principal financial center or
     centers in such participating member state or states as the Administrative
     Agent may from time to time nominate for this purpose).

          (f)  Payments to the Administrative Agent.   Sections 2.02 and 2.10
shall be construed so that, in relation to the payment of any amount of euro
units or national currency units, such amount shall be made available to the
Administrative Agent in immediately available, freely transferable, cleared
funds to such account with such bank in Frankfurt am Main, Germany (or such
other principal financial center in such participating member state as the
Administrative Agent may from time to time nominate for this purpose) as the
Administrative Agent shall from time to time nominate for this purpose.

          (g)  Payments by the Administrative Agent to the Banks.  Any amount
payable by the Administrative Agent to the Banks under this Agreement in the
currency of a participating member state shall be paid in the euro unit.

          (h)  Payments by the Administrative Agent Generally.  With respect to
the payment of any amount denominated in the euro or in a national currency
unit, the Administrative Agent shall not be liable to the Borrower or any of the
Banks in any way whatsoever for any delay, or the consequences of any delay, in
the crediting to any account of any amount required by this Agreement to be paid
by the Administrative Agent if the Administrative Agent shall have taken all
relevant steps to achieve, on the date required by this Agreement, the payment
of such amount in immediately available, freely transferable, cleared funds (in
the euro unit or, as the case may be, in a national currency unit) to the
account with the bank in the principal financial center in the participating
member state which the Borrower or, as the case may be, any Bank shall have
specified for such purpose.  In this paragraph (h), "all relevant steps" means
all such steps as may be prescribed from time to time by the regulations or
operating procedures of such clearing or settlement system as the Administrative
Agent may from time to time determine for the purpose of clearing or settling
payments of the euro.

          (i)  Basis of Accrual.  If the basis of accrual of interest or fees
expressed in this Agreement with respect to the currency of any state that
becomes a participating member state shall be inconsistent with any convention
or practice in the London Interbank Market for the basis of accrual of interest
or fees in respect of the euro, such convention or practice shall replace such
expressed basis effective as of and from the date on which such state becomes a
participating member state; provided, that if any Loan in the currency of such
                            --------                                          
state is outstanding immediately prior to such date, such replacement shall take
effect, with respect to such Loan, at the end of the then current Interest
Period for such Loan.

          (j)  Rounding and Other Consequential Changes.  Without prejudice and
in addition to any method of conversion or rounding prescribed by any EMU
legislation and without prejudice to the respective liabilities for Debt of the
Borrower to the Banks and the Banks to any Borrower under or pursuant to this
Agreement:

          (i)  each reference in this Agreement to a minimum amount (or an
     integral multiple thereof) in a national currency unit to be paid to or by
     the Administrative Agent shall be replaced by a reference to such
     reasonably comparable and convenient amount (or an integral multiple
     thereof) in the euro unit as the Administrative Agent may from time to time
     specify; and

          (ii) except as expressly provided in this Section 9.12, each provision
     of this Agreement shall be subject to such reasonable changes of
     construction as the Administrative Agent may from time to time specify to
     be necessary or appropriate to reflect the introduction of or changeover to
     the euro in participating member states.

                                  OPINION OF
                           COUNSEL FOR THE BORROWER


To the Banks and the Administrative Agent
Referred to Below
c/o The Chase Manhattan Bank,
as Administrative Agent
270 Park Avenue
New York, New York 10017

Dear Sirs:

          I have acted as counsel for Armstrong World Industries, Inc. (the
"BORROWER") in connection with the Credit Agreement (the "CREDIT AGREEMENT")
dated as of _________, 1998 among the Borrower, the banks listed on the
signature pages thereof and The Chase Manhattan Bank, as Administrative Agent.
Terms defined in the Credit Agreement are used herein as therein defined.  This
opinion is being rendered to you at the request of my client pursuant to Section
3.01(c) of the Credit Agreement.

          I have examined originals or copies, certified or otherwise identified
to my satisfaction, of such documents, corporate records, certificates of public
officials and other instruments and have conducted such other investigations of
fact and law as I have deemed necessary or advisable for purposes of this
opinion.

          I am licensed to practice law in the Commonwealth of Pennsylvania.
The law covered by this opinion is limited to the laws of the Commonwealth of
Pennsylvania and the Federal laws of the United States.  I have assumed for the
purposes of this opinion that the substantive law of the State of New York is
identical in all material respects to the substantive law of the Commonwealth of
Pennsylvania.

          Upon the basis of the foregoing, I am of the opinion that:

          (1)  The Borrower is a corporation duly incorporated, validly existing
     and in good standing under the laws of Pennsylvania, and has all corporate
     powers and all material governmental licenses, authorizations, consents and
     approvals required to carry on its business as now conducted.

          (2)  The execution, delivery and performance by the Borrower of the
     Credit Agreement is within the Borrower's corporate powers, have been duly
     authorized by all necessary corporate action, require no action by or in
     respect of, or filing with, any governmental body, agency or official and
     do not contravene, or constitute a default under, any provision of
     applicable law or regulation or of the articles of incorporation or by-laws
     of the Borrower or of any material agreement, judgment, injunction, order,
     decree or other instrument binding upon the Borrower or any of its
     Subsidiaries or result in the creation or imposition of any Lien on any
     asset of the Borrower or any of its Subsidiaries.

          (3)  The Credit Agreement constitutes a valid and binding agreement of
     the Borrower enforceable in accordance with its terms, except as the same
     may be limited by bankruptcy, insolvency or similar laws affecting
     creditors' rights generally and by general principles of equity.

                                       47
<PAGE>
 
          (4)  Except as disclosed in the Borrower's 1997 Form 10-K, in the
     Borrower's Latest Form 10-Q or in the Borrower's Schedule 14D-1 filed with
     the Securities and Exchange Commission in connection with the Offer, there
     is no action, suit or proceeding pending against, or to the best of my
     knowledge threatened against or affecting, the Borrower or any of its
     Subsidiaries before any court or arbitrator or any governmental body,
     agency or official, in which there is a reasonable possibility of an
     adverse decision which could materially adversely affect the business,
     financial position, operations or prospects of the Borrower and its
     Consolidated Subsidiaries, considered as a whole, or the ability of the
     Borrower to perform its obligations under the Credit Agreement, or which in
     any manner draws into question the validity of the Credit Agreement.

          (5)  Each of the Borrower's Significant Subsidiaries is a corporation
     validly existing and in good standing under the laws of its jurisdiction of
     incorporation, and has all corporate powers and all material governmental
     licenses, authorizations, consents and approvals required to carry on its
     business as now conducted.

                Very truly yours,

                                       48

obligated to perform the obligations of a Bank under the Credit Agreement with a
Commitment in an amount equal to the Assigned Amount, and (ii) the Commitment of
the Assignor shall, as of the date hereof, be reduced by a like amount and the

          Section 2.01. Commitments To Lend.  (a) During the Revolving Credit
Period each Bank severally agrees, on the terms and conditions set forth in this
Agreement, to make loans in U.S. Dollars and/or one or more Designated
Currencies (at the option of the Borrower) to the Borrower pursuant to this
Section from time to time in amounts such that (i) the U.S. Dollar Equivalent of

shall not exceed the amount of its Commitment and (ii) the aggregate U.S. Dollar
Equivalent of the outstanding Loans of all the Banks denominated in Foreign
Currencies shall not exceed $450,000,000.  Each Borrowing under this Section
shall be in an aggregate principal amount that is a multiple of the Borrowing
Multiple and at least equal to the Borrowing Minimum (except that any such
Borrowing may be in the aggregate amount of the unused Commitments) and shall be
made from the several Banks ratably in proportion to their respective
Commitments.  Within the foregoing limits, the Borrower may borrow under this
Section, repay, or to the extent permitted by Section 2.09, prepay Loans and
reborrow at any time during the Revolving Credit Period under this Section.

          (b)  Subject to Sections 8.01 and 8.02 (i) each Borrowing denominated
in U.S. Dollars shall be comprised entirely of Base Rate Loans or Eurocurrency
Loans as the Borrower may request pursuant to Section 2.02 and (ii) each
Borrowing denominated in a Designated Currency shall be comprised entirely of
Eurocurrency Loans.

          Section 2.02.  Procedure for Borrowing.  (a) The Borrower shall give

a.m. New York City Time on (x) the date of each Base Rate Borrowing, (y) the
third Eurocurrency Business Day before each Eurocurrency Borrowing denominated
in Dollars and (z) the fourth Eurocurrency Business Day before each Eurocurrency
Borrowing denominated in a Designated Currency, specifying:

          (i)    the date of such Borrowing, which shall be a Domestic Business
     Day in the case of a Base Rate Borrowing or a Eurocurrency Business Day in
     the case of a Eurocurrency Borrowing,

          (ii)   the aggregate amount of such Borrowing,

          (iii)  the currency of such Borrowing, if applicable;

          (iv)   in the case of a Borrowing denominated in U.S. Dollars, whether
     the Loans comprising such Borrowing are to be Base Rate Loans or
     Eurocurrency Loans, and

          (v)    in the case of a Borrowing in a Designated Currency, the
     location from which payment of the principal and interest on such Borrowing
     will be made, which shall comply with the requirements of Section 2.10;

          (vi)   the number and location of the account to which funds are to be
     disbursed; and

                                       10
<PAGE>
 
          (vii)  in the case of a Eurocurrency Borrowing, the duration of the
     Interest Period applicable thereto, subject to the provisions of the
     definition of Interest Period.

          (b)  If no election as to the type of a U.S. Dollar Borrowing is
specified in any such notice, then the requested Borrowing shall be a Base Rate
Borrowing.  If no election as to the currency of a Borrowing is specified in any
such notice, then the requested Borrowing shall be denominated in U.S. Dollars.
If no Interest Period with respect to any Eurocurrency Borrowing is specified in
any such notice then the Borrower shall be deemed to have selected an Interest
Period of one month's duration.

          (c)  Upon receipt of a Notice of Borrowing, the Administrative Agent
shall promptly notify each Bank of the contents thereof and of such Bank's share
of such Borrowing and such Notice of Borrowing shall not thereafter be revocable
by the Borrower.

          (d)  Not later than 12:00 noon New York City Time on the date of each
Borrowing, each Bank shall (except as provided in subsection (e) of this
Section) make available its share of such Borrowing in immediately available
funds as may then be customary for the settlement of transactions in the
relevant currency, to such account as the Administrative Agent shall specify.
Unless the Administrative Agent determines that any applicable condition
specified in Article 3 has not been satisfied, the Administrative Agent shall
promptly transfer the amounts so received to the account designated by the
Borrower in the applicable Notice of Borrowing.

          (e)  If any Bank makes a new Loan hereunder on a day on which the
Borrower is to repay all or any part of an outstanding Loan from such Bank, such
Bank shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference (if any) between the amount being borrowed and
the amount being repaid shall be made available by such Bank to the
Administrative Agent as provided in subsection (d), or remitted by the Borrower
to the Administrative Agent as provided in Section 2.10, as the case may be.

          (f)  Unless the Administrative Agent shall have received notice from a
Bank prior to the time of any Borrowing that such Bank will not make available
to the Administrative Agent such Bank's share of such Borrowing, the
Administrative Agent may assume that such Bank has made such share available to
the Administrative Agent on the date of such Borrowing in accordance with
subsections (d) and (e) of this Section and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Bank shall not have so
made such share available to the Administrative Agent, such Bank and, if such
Bank fails to do so within three Domestic Business Days of demand therefor, the
Borrower severally agree to repay to the Administrative Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Administrative Agent, at (i) in the case of the
Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the
interest rate applicable thereto pursuant to Section 2.05 and (ii) in the case
of such Bank, the Federal Funds Rate.  If such Bank shall repay to the
Administrative Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement.

          Section 2.03.  Evidence of Debt.  (a) Each Bank shall maintain in
accordance with its usual practice an account or accounts evidencing the
indebtedness of the Borrower to such Bank resulting from each Loan made by such
Bank, including the amounts of principal and interest payable and paid to such
Bank from time to time hereunder.

                                       11
<PAGE>
 
          (b)  The Administrative Agent shall maintain accounts in which it
shall record (i) the amount and currency of each Loan made hereunder, (ii) the
amount of any principal or interest due and payable or to become due and payable
from the Borrower to each Bank hereunder and (iii) the amount of any sum
received by the Administrative Agent hereunder for the accounts of the Banks and
each Bank's share thereof.

          (c)  The entries made in the accounts maintained pursuant to paragraph
(a) or (b) of this Section shall be prima facie evidence of the existence and
                                    -----------
amounts of the obligations recorded therein; provided that the failure of any
                                             --------
Bank or the Administrative Agent to maintain such accounts or any error therein
shall not in any manner affect the obligation of the Borrower to repay the Loans
in accordance with the terms of this Agreement.

          (d)  Any Bank may request that Loans made by it be evidenced by a
promissory note. In such event, the Borrower shall prepare, execute and deliver
to such Bank a promissory note payable to the order of such Bank (or, if
requested by such Bank, to such Bank and its registered assigns) in a form
approved by the Borrower and the Administrative Agent. Thereafter, the Loans
evidenced by such promissory note and interest thereon shall at all times
(including after assignment pursuant to Section 9.06) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

shall mature, and the principal amount thereof shall be due and payable, on the
last day of the Interest Period applicable to such Borrowing.

          Section 2.05.  Interest Rates. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, for each day from the date
such Loan is made until it becomes due, at a rate per annum equal to the Base
Rate for such day. Such interest shall be payable for each Interest Period on
the last day thereof. Any overdue principal of or interest on any Base Rate Loan
shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the sum of 2% plus the rate otherwise applicable to Base Rate
Loans for such day.

          (b)  Each Eurocurrency Loan shall bear interest on the outstanding
principal amount thereof, for each day during the Interest Period applicable
thereto, at a rate per annum equal to the sum of the Eurocurrency Margin for
such day plus the Adjusted London Interbank Offered Rate applicable to such
Interest Period. Such interest shall be payable for each Interest Period on the
last day thereof and, if such Interest Period is longer than three months, at
intervals of three months after the first day thereof.

with the Pricing Schedule.

          The "ADJUSTED LONDON INTERBANK OFFERED RATE" applicable to any
Interest Period means a rate per annum equal to the quotient obtained (rounded

          "LONDON INTERBANK OFFERED RATE" shall mean, with respect to any
Eurocurrency Borrowing, the rate per annum determined by the Administrative

Bankers' Association Interest Settlement Rates for deposits in the

                                       12
<PAGE>
 
currency of such Borrowing (as reflected on the applicable Telerate screen), for
a period equal to such Interest Period; provided that, to the extent that an
                                        -------- 
interest rate is not ascertainable pursuant to the foregoing provisions of this
definition, the "LONDON INTERBANK OFFERED RATE" shall be the interest rate per
annum determined by the Administrative Agent to be the average of the rates per
annum at which deposits in the currency of such Borrowing offered for such
relevant Interest Period to major banks in the London interbank market in
London, England, by the Administrative Agent at approximately 11:00 a.m. (London
time) on the date which is two Eurocurrency Business Days prior to the beginning
of such Interest Period.

          "QUOTATION DAY" shall mean, with respect to any currency, each day on
which rate quotations in such currency are available through the British
Bankers' Association.

          "EUROCURRENCY RESERVE PERCENTAGE" means, with respect to any currency,
a fraction (expressed as a decimal), the numerator of which is the number one
and the denominator of which is the number one minus the aggregate of the
maximum reserve, liquid asset or similar percentages (including any marginal,

by any Governmental Authority of the jurisdiction of such currency to which
banks in such jurisdiction are subject for any category of deposits or
liabilities customarily used to fund loans in such currency or by reference to
which interest rates applicable to Loans in such currency are determined.
Eurocurrency Loans shall be deemed to be subject to such reserve requirements
without benefit of or credit for proration, exemptions or offsets that may be
available from time to time to any Bank under Regulation D or any other
applicable law, rule or regulation. The Eurocurrency Reserve Percentage shall be
adjusted automatically on and as of the effective date of any change in any
reserve percentage.

          (d)  Any overdue principal of or interest on any Eurocurrency Loan
shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the higher of (i) the sum of 2% plus the Eurocurrency Margin for
such day plus the Adjusted London Interbank Offered Rate applicable to the
Interest Period for such Loan and (ii) the sum of 2% plus the Eurocurrency
Margin for such day plus the quotient obtained (rounded upward, if necessary, to
the next higher 1/100 of 1%) by dividing (x) the average (rounded to the nearest
1/16 of 1%) of the respective rates per annum at which one day (or, if such
amount due remains unpaid more than three Eurocurrency Business Days, then for
such other period of time not longer than six months as the Administrative Agent
may select) deposits in the currency of such Loan in an amount approximately
equal to such Loan are offered to the Administrative Agent in the London
interbank market for the applicable period determined as provided above by (y)
1.00 minus the Eurocurrency Reserve Percentage (or, if the circumstances
described in Section 8.01 shall exist, (i) in the case of a Loan denominated in
Dollars, at a rate per annum equal to the sum of 2% plus the rate applicable to
Base Rate Loans for such day) and (ii) in the case of a Loan denominated in
Foreign Currency, at a rate per annum equal to the sum of 2% plus the
Eurocurrency Margin plus the rate determined by the Administrative Agent from
time to time to represent the cost of overnight or short-term funds in the
applicable currency.

          (e)  The Administrative Agent shall determine each interest rate
applicable to the Loans hereunder. The Administrative Agent shall give prompt
notice to the Borrower and the Banks of each rate of interest so determined, and
its determination thereof shall be conclusive in the absence of manifest error.

          Section 2.06.  Facility Fees. (a) The Borrower shall pay to the
Administrative Agent for the account of the Banks ratably a facility fee at the
Facility Fee Rate (determined daily in accordance with the Pricing Schedule).
Such facility fee shall accrue (i) from and

<PAGE>
 
including the date of this Agreement to but excluding the Termination Date (or
earlier date of termination of the Commitments in their entirety), on the daily
aggregate amount of the Commitments (whether used or unused) and (ii) from and

Administrative Agent for the account of each Bank an upfront fee in the amount
heretofore mutually agreed.

          Section 2.07.  Optional Termination or Reduction of Commitments. (a)
During the Revolving Credit Period, the Borrower may, upon at least three
Domestic Business Days' notice to the Administrative Agent, (i) terminate the
Commitments at any time, if no Loans are outstanding at such time or (ii)
ratably reduce from time to time by an aggregate amount of $25,000,000 or any
larger multiple of $5,000,000, the aggregate amount of the Commitments in excess
of the aggregate U.S. Dollar Equivalent of the outstanding principal amount of
the Loans.

          Section 2.08.  Mandatory Termination and Reduction of Commitments. The
Commitments shall terminate on the Termination Date, and any Loans then
outstanding (together with accrued interest thereon) shall be due and payable on
such date.

          Section 2.09.  Optional Payments. (a) Subject in the case of any
Eurocurrency Borrowing to Section 2.11, the Borrower may, upon at least one
Domestic Business Day's notice to the Administrative Agent, prepay any Base Rate
Borrowing, or upon at least three Eurocurrency Business Days' notice to the
Administrative Agent, prepay any Eurocurrency Borrowing, in each case in whole
at any time, or from time to time in part in amounts that are multiples of the
Borrowing Multiple and at least equal to the Borrowing Minimum by paying the
principal amount to be prepaid together with accrued interest thereon to the
date of prepayment. Each such optional prepayment shall be applied to prepay
ratably the Loans of the several Banks included in such Borrowing.

          (b)  Upon receipt of a notice of prepayment pursuant to this Section,
the Administrative Agent shall promptly notify each Bank of the contents thereof
and of such Bank's ratable share (if any) of such prepayment and such notice
shall not thereafter be revocable by the Borrower.

          Section 2.10.  General Provisions as to Payments. (a) The Borrower
shall make each payment of principal of, and interest on, the Loans and of fees
hereunder, without setoff, counterclaim or other deduction, not later than 12:00
Noon New York City Time on the date when due, in U.S. Dollars or the applicable
Designated Currency, as the case may be, in immediately available funds to such
account as the Administrative Agent shall specify. All payments due under this
Agreement other than the payments of the principal of and interest on Loans
denominated in Foreign Currencies shall be made in U.S. Dollars. The
Administrative Agent will promptly distribute to each Bank its ratable share of
each such payment received by the Administrative Agent for the account of the
Banks. Whenever any payment of principal of, or interest on, Base Rate Loans or
of fees shall be due on a day which is not a Domestic Business Day, the date for
payment thereof shall be extended to the next succeeding Domestic Business Day.
Whenever any payment of principal of, or interest on, the Eurocurrency Loans
shall be due on a day which is not a Eurocurrency Business Day, the date for
payment thereof shall be extended to the next succeeding Eurocurrency Business
Day unless such Eurocurrency Business

                                       14
<PAGE>
 
Day falls in another calendar month, in which case the date for payment thereof
shall be the next preceding Eurocurrency Business Day. If the date for any
payment of principal is extended by operation of law or otherwise, interest
thereon shall be payable for such extended time.

          (b)  Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Banks
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank. If and to the extent that
the Borrower shall not have so made such payment, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Administrative Agent, at the Federal Funds Rate.

          Section 2.11.  Funding Losses. If (i) the Borrower makes any payment
of principal with respect to any Eurocurrency Loan (pursuant to Article 2, 6, or
8 or otherwise) or (ii) any Non-Increasing Bank receives a payment of principal
pursuant to Section 2.13(b) on any day other than the last day of the Interest
Period applicable thereto, or the last day of an applicable period fixed
pursuant to Section 2.05(d), or if the Borrower fails to borrow or prepay any
Eurocurrency Loan after notice has been given to any Bank in accordance with
Section 2.02(c) or 2.09(b), the Borrower shall reimburse each Bank within 15
days after demand for any resulting loss or reasonable expense incurred by it
(or by an existing Participant in the related Loan), including (without
limitation) any loss incurred in obtaining, liquidating or employing deposits
from third parties, but excluding loss of margin, for the period after any such
payment or failure to borrow or prepay, provided that such Bank shall have
                                        --------
delivered to the Borrower a certificate as to the amount of such loss or
expense, which certificate shall be conclusive in the absence of manifest error.

          Section 2.12.  Computation of Interest and Fees. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). Interest based on the
Federal Funds Rate or the Adjusted London Interbank Offered Rate shall be
computed on the basis of a year of 360 days, and paid for the actual number of
days elapsed (including the first day but excluding the last day). Fees shall be
computed on the basis of a year of 360 days and paid for the actual number of
days elapsed (including the first day but excluding the last day).

          Section 2.13.  Increase in Commitments. (a) The Borrower may, by
written notice to the Administrative Agent (which shall promptly deliver a copy
to each of the Banks), request that the total Commitments be increased by an
amount not less than $25,000,000 for any such increase and not greater than
$250,000,000 minus the aggregate amount of prior or simultaneous increases of
the Commitments under this Agreement and the 364-Day Agreement. Such notice
shall set forth the amount of the requested increase in the total Commitments
and the date on which such increase is requested to become effective (which
shall be not less than 45 days or more than 60 days after the date of such
notice), and shall offer each Bank the opportunity to increase its Commitment by
its Applicable Percentage of the proposed increased amount. Each Bank shall, by
notice to the Borrower and the Administrative Agent given not more than 20 days
after the date of the Borrower's notice, either agree to increase its Commitment
by all or a portion of the offered amount (each Bank so agreeing being an
"INCREASING BANK") or decline to increase its Commitment (and any Bank that does
not

                                       15
<PAGE>
 
deliver such a notice within such period of 20 days shall be deemed to have
declined to increase its Commitment) (each Bank so declining or deemed to have
declined being a "NON-INCREASING BANK"). In the event that, on the 20th day
after the Borrower shall have delivered a notice pursuant to the first sentence
of this paragraph, the Banks shall have agreed pursuant to the preceding
sentence to increase their Commitments by an aggregate amount less than the
increase in the total Commitments requested by the Borrower, the Borrower may
arrange for one or more banks or other financial institutions (any such bank or
other financial institution referred to in this paragraph (a) being called an
"AUGMENTING BANK"), which may include any Bank, to extend Commitments or

hereunder, shall be subject to the approval of the Administrative Agent (which
approval shall not be unreasonably withheld) and each Augmenting Bank shall
execute all such documentation as the Administrative Agent shall specify to
evidence its Commitment and its status as a Bank hereunder. Increases and new
Commitments created pursuant to this paragraph (a) shall become effective on the
date specified in the notice delivered by the Borrower pursuant to the first
sentence of this paragraph. Notwithstanding the foregoing, no increase in the
total Commitments (or in the Commitment of any Bank) shall become effective
under this paragraph unless, (i) on the date of such increase, the conditions

Commitment Increase on the Increase Effective Date shall be deemed to be paid,
(ii) each Increasing Bank and each Augmenting Bank that shall have been a Bank
prior to the Commitment Increase shall pay to the Administrative Agent in same
day funds an amount equal to the difference between (A) the product of (1) such
Bank's Applicable Percentage (calculated after giving effect to the Commitment
Increase) multiplied by (2) the amount of the Subsequent Borrowings (as
hereinafter defined) and (B) the product of (1) such Bank's Applicable
Percentage (calculated without giving effect to the Commitment Increase)
multiplied by (2) the amount of the Initial Loans, (iii) each Augmenting Bank
that shall not have been a Bank prior to the Commitment Increase shall pay to
Administrative Agent in same day funds an amount equal to the product of (1)
such Augmenting Bank's Applicable Percentage (calculated after giving effect to
the Commitment Increase) multiplied by (2) the amount of the Subsequent
Borrowings, (iv) after the Administrative Agent receives the funds specified in
clauses (ii) and (iii) above, the Administrative Agent shall pay to each Non-
Increasing Bank the portion of such funds that is equal to the difference
between (A) the product of (1) such Non-Increasing Bank's Applicable Percentage
(calculated without giving effect to the Commitment Increase) multiplied by (2)
the amount of the Initial Loans, and (B) the product of (1) such Non-Increasing
Bank's Applicable Percentage (calculated after giving effect to the Commitment
Increase) multiplied by (2) the amount of the Subsequent Borrowings (v) after
the effectiveness of the Commitment Increase, the Borrower shall be deemed to
have made new Borrowings (the "SUBSEQUENT BORROWINGS") in an aggregate principal
amount equal to the aggregate principal amount of the Initial Loans in the
currency or currencies, and of the types and for the Interest Periods specified

Administrative Agent in accordance with Section 2.02, (vi) each Non-Increasing
Bank, each Increasing Bank and each Augmenting Bank shall be deemed to hold its
Applicable Percentage of each Subsequent Borrowing (calculated after giving
effect to the Commitment Increase) and (vii) the Borrower shall pay each
Increasing Bank and each Non-Increasing Bank any and all accrued but unpaid
interest on the Initial Loans.

by all necessary corporate action, require no action by or in respect of, or
filing with, any governmental body, agency or official and do not contravene, or
constitute a default under, any provision of applicable law or regulation or of
the articles of incorporation or by-laws of the Borrower or of any material
agreement, judgment, injunction, order, decree or other instrument binding upon
the Borrower or any of its Subsidiaries or result in the creation or imposition
of any Lien on any asset of the Borrower or any of its Subsidiaries.

          Section 4.03.  Binding Effect. This Agreement constitutes a valid and
binding agreement of the Borrower, enforceable in accordance with its terms and
each note, when executed and delivered in accordance with this Agreement will
constitute a valid and binding obligation of the Borrower in each case
enforceable in accordance with its terms.

          Section 4.04.  Financial Information. (a) The consolidated balance
sheet of the Borrower and its Consolidated Subsidiaries as of December 31, 1997
and the related consolidated statements of earnings and cash flows for the
fiscal year then ended, reported on by independent public accountants and set
forth in the Borrower's 1997 Form 10-K, a copy of which has been delivered to
each of the Banks, fairly present, in conformity with generally accepted
accounting principles, the consolidated financial position of the Borrower and
its Consolidated Subsidiaries as of such date and their consolidated results of
operations and cash flows for such fiscal year.

          (b)  The unaudited consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries as of June 30, 1998 and the related unaudited
consolidated statements of earnings and cash flows for the six months then

accepted accounting principles applied on a basis consistent with the financial
statements referred to in subsection (a) of this Section, the consolidated
financial position of the Borrower and its Consolidated Subsidiaries as of such
date and their consolidated results of operations and cash flows for such three
month period (subject to normal year-end adjustments).

          Section 4.05.  Litigation. Except as disclosed in the Borrower's 1997
Form 10-K, in the Borrower's Latest Form 10-Q or as may hereafter be disclosed
in writing by the Borrower to the Banks or in reports filed with the Securities
and Exchange Commission, there is no action, suit or proceeding pending against,
or to the knowledge of the Borrower threatened against or affecting, the
Borrower or any of its Subsidiaries before any court or arbitrator or any
governmental body, agency or official in which there is a reasonable possibility
of an adverse decision which could materially adversely affect the business,
financial position, operations or prospects of the Borrower and its Consolidated
Subsidiaries, considered as a whole, or the ability of the Borrower to perform
its obligations under this Agreement. There is no action, suit or proceeding
pending against, or the knowledge of the Borrower threatened against or
affecting, the Borrower or any of its Subsidiaries before any court or
arbitrator or any governmental body, agency or official which in any manner
draws into question the validity of this Agreement.

          Section 4.06.  Environmental Matters. In the ordinary course of its
business, the Borrower reviews the effect of Environmental Laws on the business,
operations and properties of the Borrower and its Subsidiaries, in the course of
which it identifies and evaluates associated liabilities and costs. On the basis
of this review, the Borrower has reasonably concluded that, to the best of its
knowledge, except as disclosed in reports filed with the Securities and Exchange
Commission, copies of which reports have been delivered to the Banks, such
associated liabilities and costs, including the costs of compliance with
Environmental Laws, are unlikely to have a material adverse effect on the
business, financial condition, results of operations or prospects of the
Borrower and its Consolidated Subsidiaries, considered as a whole.

          Section 4.07.  Taxes. The Borrower and its Subsidiaries have filed all
United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes due pursuant to
such returns or pursuant to any assessment received by the Borrower or any
Subsidiary. The charges, accruals and reserves on the books of the Borrower and
its Subsidiaries in respect of taxes or other governmental charges are, in the
opinion of the Borrower, adequate.

          Section 4.08.  Significant Subsidiaries. Each of the Borrower's
Significant Subsidiaries is a corporation duly incorporated, validly existing
and in good standing under the laws of its jurisdiction of incorporation, and
has all corporate powers and all material governmental licenses, authorizations,
consents and approvals required to carry on its business as now conducted.

          Section 4.09.  Not an Investment Company. The Borrower is not an
"Investment Company" within the meaning of the Investment Company Act of 1940,
as amended.

          Section 4.10   Full Disclosure. All information heretofore furnished
by the Borrower to the Administrative Agent or any Bank for purposes of or in
connection with this Agreement or any transaction contemplated hereby is, and
all such information hereafter furnished by the Borrower to the Administrative
Agent or any Bank will be, true and accurate in all material respects on the
date as of which such information is stated or certified. The Borrower has
disclosed to the Banks in writing or in reports filed with the Securities and
Exchange Commission, copies of which reports have been delivered to the Banks,
any and all facts which materially and adversely affect or may affect (to the
extent the Borrower can now reasonably foresee) the business, operations or
financial condition of the Borrower and its Consolidated Subsidiaries, taken as
a whole, or the ability of the Borrower to perform its obligations under this
Agreement.

          (d) any representation, warranty, certification or statement made by

     corporate action to authorize any of the foregoing;

          (h) an involuntary case or other proceeding shall be commenced against
     the Borrower or any Significant Subsidiary seeking liquidation,
     reorganization or other relief with respect to it or its debts under any
     bankruptcy, insolvency or other similar law now or hereafter in effect or
     seeking the appointment of a trustee, receiver, liquidator, custodian or

     administer any Material Plan; (D) a condition shall exist by reason of
     which the PBGC would be entitled to obtain a decree adjudicating that any
     Material Plan must be terminated; or (E) there shall occur a complete or
     partial withdrawal from, or a default, within the meaning of Section
     4219(c)(5) of ERISA, with respect to, one or more Multiemployer Plans and
     such events listed in clauses (A) through (E) could cause one or more
     members of the ERISA Group to incur a current payment obligation in excess
     of $20,000,000;

          (j) judgments or orders for the payment of money in excess of

  notice to the Borrower terminate the Commitments and they shall thereupon
  terminate, and (ii) if requested by Banks with Loans of more than 51% in
  aggregate principal amount of the Loans, by notice to the Borrower declare the
  Loans (together with accrued interest thereon) to be, and the Loans shall
  thereupon become, immediately due and payable, without presentment, demand,
  protest or any other notice of any kind, all of which are hereby expressly
  waived by the Borrower; provided that in the case of any of the Events of
                          --------

                                   ARTICLE 7

                                  The Agents

          Section 7.01.  Appointment and Authorization.  Each Bank irrevocably
appoints and authorizes the Administrative Agent to take such action as
Administrative Agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof or
thereof, together with all such powers as are reasonably incidental thereto.

          Section 7.02.  Administrative Agent and Affiliates.  The Chase
Manhattan Bank of New York shall have the same rights and powers under this
Agreement as any other Bank and may exercise or refrain from exercising the same
as though it were not the Administrative Agent, and The Chase Manhattan Bank and
its affiliates may accept deposits from, lend money to, and generally engage in
any kind of business with the Borrower or any Subsidiary or affiliate of the
Borrower as if it were not the Administrative Agent hereunder.

          Section 7.03.  Action by Administrative Agent.  The obligations of the
Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action with respect to any Default, except as
expressly provided in Article 6.

          Section 7.04.  Consultation with Experts.  The Administrative Agent
may consult with legal counsel (who may be counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

          Section 7.05.  Liability of Administrative Agent. Neither the
Administrative Agent nor any of its affiliates nor any of their respective
directors, officers, agents or employees shall be liable for any action taken or
not taken by it in connection herewith (i) with the consent

                                       25
<PAGE>
 
or at the request of the Required Banks or (ii) in the absence of its own gross
negligence or willful misconduct. Neither the Administrative Agent nor any of
its affiliates nor any of their respective directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with
this Agreement or any borrowing hereunder; (ii) the performance or observance of
any of the covenants or agreements of the Borrower; (iii) the satisfaction of
any condition specified in Article 3, except receipt of items required to be
delivered to the Administrative Agent; or (iv) the validity, effectiveness or
genuineness of this Agreement or any other instrument or writing furnished in
connection herewith. The Administrative Agent shall not incur any liability by
acting in reliance upon any notice, consent, certificate, statement, or other
writing (which may be a bank wire, telex, facsimile transmission or similar
writing) believed by it to be genuine or to be signed by the proper party or
parties.

          Section 7.06.  Indemnification.  Each Bank shall, ratably in
accordance with its Commitment, indemnify the Administrative Agent, its
affiliates and their respective directors, officers, agents and employees (to
the extent not reimbursed by the Borrower) against any cost, expense (including
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from such indemnitees' gross negligence or willful
misconduct) that such indemnitees may suffer or incur in connection with this
Agreement or any action taken or omitted by such indemnitees hereunder.

          Section 7.07.  Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon any Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it will, independently and without reliance upon any Agent or
any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

          Section 7.08.  Successor Administrative Agent.  The Administrative
Agent may resign at any time by giving notice thereof to the Banks and the
Borrower.  Upon any such resignation, the Borrower shall have the right to
appoint a successor Administrative Agent, subject to the approval of the
Required Banks.  If no successor Administrative Agent shall have been so
appointed and approved, and shall have accepted such appointment, within 45 days
after the retiring Administrative Agent gives notice of resignation, then the
retiring Administrative Agent may, on behalf of the Banks, appoint a successor
Administrative Agent, which shall be a commercial bank organized or licensed
under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $50,000,000.  Upon the
acceptance of its appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder.  After any retiring Administrative
Agent's resignation hereunder as Administrative Agent, the provisions of this
Article shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent.

          Section 7.09.  Agents' Fees.  The Borrower shall pay to each Agent for
its own account fees in the amounts and at the times previously agreed upon
between the Borrower and such Agent.

Agents or the Syndication Agent in such capacity.

                                   ARTICLE 8

                            Change in Circumstances

          Section 8.01.  Basis for Determining Interest Rate Inadequate.  If on
or prior to the first day of any Interest Period for any Eurocurrency Borrowing,
the Administrative Agent is advised by the Required Banks that deposits in
Dollars (in the applicable amounts) are not being offered to the Required Banks
in the relevant market for such Interest Period, the Administrative Agent shall
forthwith give notice thereof to the Borrower and the Banks, whereupon until the
Administrative Agent notifies the Borrower that the circumstances giving rise to
such suspension no longer exist, the obligations of the Banks to make
Eurocurrency Loans shall be suspended. Unless the Borrower notifies the
Administrative Agent at least two Domestic Business Days before the date of any
Eurocurrency Borrowing for which a Notice of Borrowing has previously been given
that it elects not to borrow such Borrowing on such date, such Borrowing shall
instead be made as a Base Rate Borrowing.

          Section 8.02.  Illegality.  If, on or after the date of this
Agreement, the adoption of any applicable law, rule or regulation, or any change
in any applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Eurocurrency Lending Office) with any formal
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for any Bank (or its Eurocurrency Lending Office) to make, maintain
or fund its Dollar-Denominated Eurocurrency Loans or Eurocurrency Loans
denominated in a Designated Currency, as the case may be, and such Bank shall so
notify the Administrative Agent, the Administrative Agent shall forthwith give
notice thereof to the other Banks and the Borrower, whereupon until such Bank
notifies the Borrower and the Administrative Agent that the circumstances giving
rise to such suspension no longer exist, the obligation of such Bank to make
Dollar-denominated Eurocurrency Loans or Eurocurrency Loans denominated in a
Designated Currency shall be suspended.  Before giving any notice to the
Administrative Agent pursuant to this Section, such Bank shall designate a
different Eurocurrency Lending Office if such designation will avoid the need
for giving such notice and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank.  If such Bank shall determine that it may not
lawfully continue to maintain and fund any of its outstanding Dollar-denominated
Eurocurrency Loans or Eurocurrency Loans denominated in a Designated Currency to
maturity and shall so specify in such notice, the Borrower shall immediately
prepay in full the then outstanding principal amount of each such Eurocurrency
Loan, together with accrued interest thereon.  Concurrently with prepaying each
such Eurocurrency Loan, the Borrower shall borrow a Base Rate Loan in an equal
principal amount (or, in the case of a Eurocurrency Loan in a Designated
Currency, a Dollar amount equal to such amount based on the current Exchange
Rate) from such Bank (on which interest and principal shall be payable
contemporaneously with the related Eurocurrency Loans of the other Banks), and
such Bank shall make such a Base Rate Loan.

          Section 8.03.  Increased Cost and Reduced Return.  (a)  If on or after
the date hereof, the adoption of any applicable law, rule or regulation, or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) with any
formal request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall impose, modify or deem
applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System, but excluding
with respect to any Eurocurrency Loan any such requirement included in an
applicable Eurocurrency Reserve Percentage), special deposit, insurance
assessment or similar requirement against assets of, deposits with or for the
account of, or credit extended by, any Bank (or its Applicable Lending Office)
or shall impose on any Bank (or its Applicable Lending Office) or on the London
interbank market any other condition affecting its Eurocurrency Loans or its
obligation to make Eurocurrency Loans and the result of any of the foregoing is
to increase the cost to such Bank (or its Applicable Lending Office) of making
or maintaining any Eurocurrency Loan, or to reduce the amount of any sum
received or receivable by such Bank (or its Applicable Lending Office) under
this Agreement by an amount deemed by such Bank to be material, then, within 15
days after demand by such Bank (with a copy to the Administrative  Agent), the
Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank for such increased cost or reduction.

          (b)  If any Bank shall have determined that, after the date hereof,
the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any formal request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency (including any determination by any such authority,
central bank or comparable agency that, for purposes of capital adequacy
requirements, the Commitments hereunder do not constitute commitments with an
original maturity of one year or less), has or would have the effect of reducing
the rate of return on capital of such Bank (or its Parent) as a consequence of
such Bank's obligations hereunder to a level below that which such Bank (or its
Parent) could have achieved but for such adoption, change, request or directive
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, within 15
days after demand by such Bank (with a copy to the Administrative Agent), the
Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank (or its Parent) for such reduction.

          (c)  Each Bank will promptly notify the Borrower and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Bank to compensation pursuant to this
Section and will designate a different Applicable Lending Office if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the judgment of such Bank, be otherwise disadvantageous to such
Bank.  A certificate of any Bank claiming compensation under this Section and
setting forth the additional amount or amounts to be paid to it hereunder shall
be conclusive in the absence of manifest error.  In determining such amount,
such Bank may use any reasonable averaging and attribution methods.

          Section 8.04.  (a)  Taxes.  For purposes of this Section 8.04, the
following terms have the following meanings:

                                       28
<PAGE>
 
          "TAXES" means any and all present or future taxes, duties, levies,
     imposts, deductions, charges or withholdings with respect to any payment by
     the Borrower pursuant to this Agreement and all liabilities with respect
     thereto, excluding (i) in the case of each Bank and the Administrative
     Agent, taxes imposed on its income, and franchise or similar taxes imposed
     on it, by a jurisdiction under the laws of which such Bank or the
     Administrative Agent (as the case may be) is organized or in which its
     principal executive office is located or, in the case of each Bank, in
     which its Applicable Lending Office is located and (ii) in the case of each
     Bank, any United States withholding tax imposed on such payments but only
     to the extent that such Bank is subject to United States withholding tax at
     the time such Bank first becomes a party to this Agreement.

          "OTHER TAXES" means any present or future stamp or documentary taxes
     and any other excise or property taxes, or similar charges or levies, which
     arise from any payment made pursuant to this Agreement or from the
     execution or delivery of, or otherwise with respect to, this Agreement.

          (b)  Any and all payments by the Borrower to or for the account of any
Bank or the Administrative Agent hereunder shall be made without deduction for
any Taxes or Other Taxes; provided that, if the Borrower shall be required by
                          --------                                           
law to deduct any Taxes or Other Taxes from any such payments, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 8.04) such Bank or the Administrative Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Administrative Agent, at its address referred to in Section 9.01,
the original or a certified copy of a receipt evidencing payment thereof.

          (c)  The Borrower agrees to indemnify each Bank and the Administrative
Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section 8.04) paid by such Bank or the Administrative
Agent (as the case may be) and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto.  This indemnification shall
be paid within 15 days after such Bank or the Administrative Agent (as the case
may be) makes demand therefor.

          (d)  (i) With respect to any payment by the Borrower (or a Subsidiary)
from the United States, each Bank organized under the laws of a jurisdiction
outside the United States, on or prior to the date of its execution and delivery
of this Agreement in the case of each Bank listed on the signature pages hereof
and on or prior to the date on which it becomes a Bank in the case of each other
Bank, and from time to time thereafter if requested in writing by the Borrower
(but only so long as such Bank remains lawfully able to do so), shall provide
the Borrower with Internal Revenue Service Form 1001 or 4224, as appropriate, or
any successor form prescribed by the Internal Revenue Service, certifying that
such Bank is entitled to benefits under an income tax treaty to which the United
States is a party which exempts the Bank from United States withholding tax or
reduces the rate of withholding tax on payments of interest for the account of
such Bank or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States; provided that such Bank shall not be required to deliver any form
        --------                                                         
pursuant to this Section 8.05(d)(i) that such Bank is not legally able to
deliver.

                                       29
<PAGE>
 
          (ii) With respect to any payment by the Borrower (or a Subsidiary)
from a jurisdiction other than the United States, each Bank organized under the
laws of a jurisdiction other than the jurisdiction from which payment is made
("RELEVANT JURISDICTION") that is entitled to an exemption from or reduction of
withholding tax under the law of the Relevant Jurisdiction, or any treaty to
which such Relevant Jurisdiction is a party, with respect to payments under this
Agreement shall, after having received written notice from the Borrower (or the
applicable Subsidiary) advising it of the availability of such exemption or
reduction and containing all relevant documentation, deliver to the Borrower (or
the applicable Subsidiary), with a copy to the Administrative Agent, at the time
or times prescribed by the applicable law, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Borrower (or the applicable Subsidiary) as will permit such payments to be made
without withholding at a reduced rate.

          (e)  For any period with respect to which a Bank has failed to provide
the Borrower with the appropriate form pursuant to Section 8.04(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which such form originally was required to be provided), such Bank
shall not be entitled to indemnification under Section 8.04(b) or 8.04(c) with
respect to Taxes imposed by the Relevant Jurisdiction or the United States, as
the case may be; provided that if a Bank, which is otherwise exempt from or
                 --------                                                  
subject to a reduced rate of withholding tax, becomes subject to Taxes because
of its failure to deliver a form required hereunder, the Borrower shall take
such steps as such Bank shall reasonably request to assist such Bank to recover
such Taxes.

          (f)  If the Borrower is required to pay additional amounts to or for
the account of any Bank pursuant to this Section 8.04, then such Bank will
change the jurisdiction of its Applicable Lending Office if, in the judgment of
such Bank, such change (i) will eliminate or reduce any such additional payment
which may thereafter accrue and (ii) is not otherwise disadvantageous to such
Bank.

          Section 8.05.  Base Rate Loans Substituted for Affected Eurocurrency
Loans.  If (i) the obligation of any Bank to make Eurocurrency Loans has been
suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation
under Section 8.03 or 8.04 with respect to its Eurocurrency Loans and the
Borrower shall, by at least five Eurocurrency Business Days' prior notice to
such Bank through the Administrative Agent, have elected that the provisions of
this Section shall apply to such Bank, then, unless and until such Bank notifies
the Borrower that the circumstances giving rise to such suspension or demand for
compensation no longer exist:

          (a) all Loans which would otherwise be made by such Bank as
     Eurocurrency Loans, shall be made instead as Base Rate Loans (on which
     interest and principal shall be payable contemporaneously with the related
     Eurocurrency Loans of the other Banks), and

          (b) after each of its Eurocurrency Loans has been repaid, all payments
     of principal which would otherwise be applied to repay such Eurocurrency
     Loans shall be applied to repay its Base Rate Loans instead.

          Section 8.06.  Substitution of Bank.  If (i) the obligation of any
Bank to make Eurocurrency Loans has been suspended pursuant to Section 8.02 or
(ii) any Bank has demanded compensation under Section 8.03 or 8.04, the Borrower
shall have the right, with the assistance of the Administrative

                                       30
<PAGE>
 
  Agent, to seek a mutually satisfactory substitute bank or banks (which may be
  one or more of the Banks) to assume the Commitment of such Bank.

                                 Miscellaneous

          Section 9.01.  Notices.  All notices, requests and other
communications to any party hereunder shall be in writing (including bank wire,
telex, facsimile transmission or similar writing) and shall be given to such
party:  (x) in the case of the Borrower or the Administrative Agent, at its
address, facsimile number or telex number set forth on the signature pages
hereof, (y) in the case of any Bank, at its address, facsimile number or telex
number set forth in its Administrative Questionnaire or (z) in the case of any
party, such other address, facsimile number or telex number as such party may
hereafter specify for the purpose by notice to the Administrative Agent and the
Borrower.  Each such notice, request or other communication shall be effective
(i) if given by telex, when such telex is transmitted to the telex number
specified in this Section and the appropriate answerback is received, (ii) if
given by facsimile transmission, when transmitted to the facsimile number
specified in this Section and confirmation of receipt is received or (iii) if

         --------                                                            
Article 8 shall not be effective until received.

          Section 9.02.  No Waivers.  No failure or delay by the Administrative
Agent or any Bank in exercising any right, power or privilege hereunder shall
operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege.  The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

          Section 9.03.  Expenses; Indemnification.  (a)  The Borrower shall pay
(i) all reasonable out-of-pocket expenses of the Administrative Agent, including
fees and disbursements of special counsel for the Administrative Agent, in
connection with the preparation and administration of this Agreement, any waiver
or consent hereunder or any amendment hereof or any Default or alleged Default
hereunder and (ii) if an Event of Default occurs, all reasonable out-of-pocket
expenses incurred by the Administrative Agent and each Bank, including (without
duplication) the fees and  disbursements of outside counsel and the allocated
cost of inside counsel, in connection with such Event of Default and collection,
bankruptcy, insolvency and other enforcement proceedings resulting therefrom.

          (b)  The Borrower agrees to indemnify the Administrative Agent and
each Bank, their respective affiliates and the respective directors, officers,
agents and employees of the foregoing (each an "INDEMNITEE") and hold each
Indemnitee harmless from and against any and all liabilities, losses, damages,
reasonable costs and expenses of any kind, including, without limitation, the
reasonable fees and disbursements of counsel, which may be incurred by such
Indemnitee in connection with any investigative, administrative or judicial
proceeding (whether or not such Indemnitee shall be designated a party thereto)
brought or threatened relating to or arising out of this Agreement or any actual
or proposed use of proceeds of Loans hereunder; provided that (i) no Indemnitee
                                                --------                       
shall have the right to be indemnified hereunder for such Indemnitee's own gross
negligence or willful misconduct as determined by a court of competent
jurisdiction, (ii) in the case of an investigation or a proceeding to which an
Indemnitee is not a party, such Indemnitee shall be entitled to indemnification
only if such Indemnitee is required to respond to process or other formal
inquiry in connection therewith and (iii) any claim for

                                       31
<PAGE>
 
indemnification hereunder shall be made not later than three years after the
termination of the Commitments and repayment in full of the Loans.

          Section 9.04.  Sharing of Set-Offs.  The Banks agree among themselves
that if any Bank shall, by exercising any right of set-off or counterclaim or
otherwise, receive payment of a proportion of the aggregate amount of principal
and interest due with respect to any Loan made by it which is greater than the
proportion received by any other Bank in respect of the aggregate amount of
principal and interest due with respect to any Loan made by such other Bank, the
Bank receiving such proportionately greater payment shall purchase such
participations in the Loans made by the other Banks, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Loans made by the Banks shall be shared by the
Banks pro rata; provided that nothing in this Section shall impair the right of
                --------                                                       
any Bank to exercise any right of set-off or counterclaim it may have and to
apply the amount subject to such exercise to the payment of indebtedness of the
Borrower other than its indebtedness hereunder.

          Section 9.05.  Amendments and Waivers.  Any provision of this
Agreement may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by the Borrower and the Required Banks (and, if the
rights or duties of the Administrative Agent are affected thereby, by the
Administrative Agent); provided that no such amendment or waiver shall, unless
                       --------                                               
signed by all the Banks, (i) increase or decrease the Commitment of any Bank
(except for a ratable decrease in the Commitments of all Banks) or subject any
Bank to any additional obligation, (ii) reduce the principal of or rate of
interest on any Loan or any fees hereunder, (iii) postpone the date fixed for
any payment of principal of or interest on any Loan or any fees hereunder or for
termination of any Commitment or (iv) change the percentage of the Commitments
or of the aggregate unpaid principal amount of the Loans, or the number of
Banks, which shall be required for the Banks or any of them to take any action
under this Section or any other provision of this Agreement.

          Section 9.06.  Successors and Assigns.  (a)  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

          (b)  Any Bank may at any time grant to one or more banks or other
institutions (each a "PARTICIPANT") participating interests in its Commitment or
any or all of its Loans.  In the event of any such grant by a Bank of a
participating interest to a Participant, such Bank shall remain responsible for
the performance of its Commitment and its other obligations hereunder, and the
Borrower and the Administrative Agent shall continue to deal solely and directly
with such Bank in connection with such Bank's rights and obligations under this
Agreement.  Any agreement pursuant to which any Bank may grant such a
participating interest shall provide that such Bank shall retain the sole right
and responsibility to enforce the obligations of the Borrower hereunder
including, without limitation, the right to approve any amendment, modification
or waiver of any provision of this Agreement; provided that such participation
                                              --------                        
agreement may provide that such Bank will not agree to any modification,
amendment or waiver of this Agreement described in clause (i), (ii), (iii) or
(iv) of Section 9.05 without the consent of the Participant.  The Borrower
agrees that each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of Article with respect to its
participating interest.  An assignment or other transfer which is not permitted
by subsection (c) or (d) below shall be given effect for purposes of this
Agreement only to the extent of a participating interest granted in accordance
with this subsection (b).

                                       32

          (c)  Any Bank may at any time assign to one or more banks or other
institutions (each an "ASSIGNEE") all, or a proportionate part of all, of its
rights and obligations under this Agreement, and such Assignee shall assume such
rights and obligations, pursuant to an Assignment and Assumption Agreement in
substantially the form of Exhibit D hereto executed by such Assignee and such
transferor Bank, with (and subject to) the subscribed consent of the Borrower
and the Administrative Agent, which consents will not be unreasonably withheld;
provided that (i) if an Assignee is a Bank prior to giving effect to such
- --------                                                                 
assignment or is an affiliate of such transferor Bank, no such consent shall be
required and (ii) if at the time of such assignment an Event of Default shall
have occurred and be continuing, no such consent of the Borrower shall be
required.  Upon execution and delivery of such instrument and payment by such
Assignee to such transferor Bank of an amount equal to the purchase price agreed
between such transferor Bank and such Assignee, such Assignee shall be a Bank
party to this Agreement and shall have all the rights and obligations of a Bank
with a Commitment as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required.  In connection with any such assignment, the transferor Bank shall pay
to the Administrative Agent an administrative fee for processing such assignment
in the amount of $2,500.  If the Assignee is not incorporated under the laws of
the United States of America or a state thereof, it shall deliver to the
Borrower and the Administrative Agent certification as to exemption from
deduction or withholding of any United States federal income taxes in accordance
with Section 8.04.

          (d)  Any Bank may at any time assign all or any portion of its rights
under this Agreement to a Federal Reserve Bank.  No such assignment shall
release the transferor Bank from its obligations hereunder.

          (e)  No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.02, 8.03 or requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

          Section 9.07.  Collateral.  Each of the Banks represents to each Agent
and each of the other Banks that it in good faith is not relying upon any Margin
Stock as collateral in the extension or maintenance of the credit provided for
in this Agreement.

          Section 9.08  Governing Law; Submission to Jurisdiction.  This
Agreement shall be governed by and construed in accordance with the laws of the
State of New York.  The Borrower hereby submits to the nonexclusive jurisdiction
of the United States District Court for the Southern District of New York and of
any New York State court sitting in New York City for purposes of all legal
proceedings arising out of or relating to this Agreement or the transactions
contemplated hereby.  The Borrower irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of the venue of any such proceeding brought in such a court and any claim that
any such proceeding brought in such a court has been brought in an inconvenient
forum.

          Section 9.09.  Counterparts; Integration.  This Agreement may be
signed in any number of counterparts, each of which shall be an original, with
the same effect as if the signatures thereto and hereto were upon the same
instrument.  This Agreement constitutes the

                                       33
<PAGE>
 
entire agreement and understanding among the parties hereto and supersedes any
and all prior agreements and understandings, oral or written, relating to the
subject matter hereof.

          SECTION 9.10.  WAIVER OF JURY TRIAL.  EACH OF THE BORROWER, THE
ADMINISTRATIVE AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT
TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          Section 9.11.  Conversion of Currencies.  (a)  If, for the purpose of
obtaining judgment in any court, it is necessary to convert a sum owing
hereunder in one currency into another currency, each party hereto agrees, to
the fullest extent that it may lawfully do so, that the rate of exchange used
shall be that at which in accordance with normal banking procedures in the
relevant jurisdiction the first currency could be purchased with such other
currency on the Domestic Business Day (or Eurocurrency Business Day if
applicable) immediately preceding the day on which final judgment is given.

          (b)  The obligations of each party hereto in respect of any sum due to
any other party hereto or any holder of the obligations owing hereunder (the
"APPLICABLE CREDITOR") shall, notwithstanding any judgment in a currency (the
"JUDGMENT CURRENCY") other than the currency in which such sum is stated to be
due hereunder (the "AGREEMENT CURRENCY"), be discharged only to the extent that,
on the Business Day following receipt by the Applicable Creditor of any sum
adjudged to be so due in the Judgment Currency, the Applicable Creditor may in
accordance with normal banking procedures in the relevant jurisdiction purchase
the Agreement Currency with the Judgment Currency; if the amount of the
Agreement Currency so purchased is less than the sum originally due to the
Applicable Creditor in the Agreement Currency, such party agrees, as a separate
obligation and notwithstanding any such judgment, to indemnify the Applicable
Creditor against such loss.  The obligations of the parties contained in this
Section 9.11 shall survive the termination of this Agreement and the payment of
all other amounts owing hereunder.

          Section 9.12. European Economic and Monetary Union. (a) Definitions.
In this Section 9.12 and in each other provision of this Agreement to which
reference is made in this Section 9.12 expressly or impliedly, the following
terms have the meanings given to them in this Section 9.12:

          "COMMENCEMENT OF THE THIRD STAGE OF EMU" means the date of
     commencement of the third stage of EMU (at the date of this Credit
     Agreement expected to be January 1, 1999) or the date on which
     circumstances arise which (in the opinion of the Administrative Agent) have
     substantially the same effect and result in substantially the same
     consequences as commencement of the third stage of EMU as contemplated by
     the Treaty on European Union.

          "EMU" means economic and monetary union as contemplated in the Treaty
     on European Union.

          "EMU LEGISLATION" means legislative measures of the European Council

          "EURO" means the single currency of participating member states of the
     European Union;

                                       34

          "TREATY ON EUROPEAN UNION" means the Treaty of Rome of March 25, 1957,
     as amended by the Single European Act 1986 and the Maastricht Treaty (which
     was signed at Maastricht on February 7, 1992, and came into force on
     November 1, 1993), as amended from time to time.

          (b)  Effectiveness of Provisions.  The provisions of paragraphs (c) to
(j) below (inclusive) shall be effective at and from the commencement of the
third stage of EMU, provided, that if and to the extent that any such provision
                    --------                                                   
relates to any state (or the currency of such state) that is not a participating
member state on the commencement of the third stage of EMU, such provision shall
become effective in relation to such state (and the currency of such state) at
and from the date on which such state becomes a participating member state.

          (c)  Redenomination and Foreign Currencies.  Each obligation under
this Agreement of a party to this Agreement which has been denominated in the
national currency unit of a participating member state shall be redenominated
into the euro unit in accordance with EMU legislation, provided, that if and to
                                                       --------                
the extent that any EMU legislation provides that following the commencement of
the third stage of EMU an amount denominated either in the euro or in the
national currency unit of a participating member state and payable within that
participating member state by crediting an account of the creditor can be paid
by the debtor either in the euro unit or in that national currency unit, each
party to this Agreement shall be entitled to pay or repay any such amount either
in the euro unit or in such national currency unit.

          (d)  Loans.  Any Loan in the currency of a participating member state
shall be made or issued in the euro unit.

          (e)  Business Days.  With respect to any amount denominated or to be
denominated in the euro or a national currency unit, any reference to a
"Business Day" shall be construed as a reference to a day (other than a Saturday
or Sunday) on which banks are generally open for business in

          (i)  London and New York City and

          (ii) Frankfurt am Main, Germany (or such principal financial center or
     centers in such participating member state or states as the Administrative
     Agent may from time to time nominate for this purpose).

          (f)  Payments to the Administrative Agent.  Sections 2.02 and 2.10
shall be construed so that, in relation to the payment of any amount of euro
units or national currency units, such amount shall be made available to the
Administrative Agent in immediately available, freely transferable, cleared
funds to such account with such bank in Frankfurt am Main, Germany (or such
other principal financial center in such participating member state as the
Administrative Agent may from time to time nominate for this purpose) as the
Administrative Agent shall from time to time nominate for this purpose.

                                       35
<PAGE>
 
          (g)  Payments by the Administrative Agent to the Banks.  Any amount
payable by the Administrative Agent to the Banks under this Agreement in the
currency of a participating member state shall be paid in the euro unit.

          (h)  Payments by the Administrative Agent Generally.  With respect to
the payment of any amount denominated in the euro or in a national currency
unit, the Administrative Agent shall not be liable to the Borrower or any of the
Banks in any way whatsoever for any delay, or the consequences of any delay, in
the crediting to any account of any amount required by this Agreement to be paid
by the Administrative Agent if the Administrative Agent shall have taken all
relevant steps to achieve, on the date required by this Agreement, the payment
of such amount in immediately available, freely transferable, cleared funds (in
the euro unit or, as the case may be, in a national currency unit) to the
account with the bank in the principal financial center in the participating
member state which the Borrower or, as the case may be, any Bank shall have
specified for such purpose.  In this paragraph (h), "all relevant steps" means
all such steps as may be prescribed from time to time by the regulations or
operating procedures of such clearing or settlement system as the Administrative
Agent may from time to time determine for the purpose of clearing or settling
payments of the euro.

          (i)  Basis of Accrual.  If the basis of accrual of interest or fees
expressed in this Agreement with respect to the currency of any state that
becomes a participating member state shall be inconsistent with any convention
or practice in the London Interbank Market for the basis of accrual of interest
or fees in respect of the euro, such convention or practice shall replace such
expressed basis effective as of and from the date on which such state becomes a
participating member state; provided, that if any Loan in the currency of such
                            --------                                          
state is outstanding immediately prior to such date, such replacement shall take
effect, with respect to such Loan, at the end of the then current Interest
Period for such Loan.

          (j)  Rounding and Other Consequential Changes.  Without prejudice and
in addition to any method of conversion or rounding prescribed by any EMU
legislation and without prejudice to the respective liabilities for Debt of the
Borrower to the Banks and the Banks to any Borrower under or pursuant to this
Agreement:

          (i) each reference in this Agreement to a minimum amount (or an
     integral multiple thereof) in a national currency unit to be paid to or by
     the Administrative Agent shall be replaced by a reference to such
     reasonably comparable and convenient amount (or an integral multiple
     thereof) in the euro unit as the Administrative Agent may from time to time
     specify; and

          (ii) except as expressly provided in this Section 9.12, each provision
     of this Agreement shall be subject to such reasonable changes of
     construction as the Administrative Agent may from time to time specify to
     be necessary or appropriate to reflect the introduction of or changeover to
     the euro in participating member states.

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed by their respective authorized officers as of the day and year
first above written.

                                  OPINION OF
                           COUNSEL FOR THE BORROWER

To the Banks and the Administrative Agent
Referred to Below
c/o The Chase Manhattan Bank,
as Administrative Agent
270 Park Avenue
New York, New York 10017

Dear Sirs:

          I have acted as counsel for Armstrong World Industries, Inc. (the
"BORROWER") in connection with the Credit Agreement (the "CREDIT AGREEMENT")
dated as of _________, 1998 among the Borrower, the banks listed on the
signature pages thereof and The Chase Manhattan Bank, as Administrative Agent.
Terms defined in the Credit Agreement are used herein as therein defined.  This
opinion is being rendered to you at the request of my client pursuant to Section
3.01(c) of the Credit Agreement.

          I have examined originals or copies, certified or otherwise identified
to my satisfaction, of such documents, corporate records, certificates of public
officials and other instruments and have conducted such other investigations of
fact and law as I have deemed necessary or advisable for purposes of this
opinion.

          I am licensed to practice law in the Commonwealth of Pennsylvania.
The law covered by this opinion is limited to the laws of the Commonwealth of
Pennsylvania and the Federal laws of the United States.  I have assumed for the
purposes of this opinion that the substantive law of the State of New York is
identical in all material respects to the substantive law of the Commonwealth of
Pennsylvania.

          Upon the basis of the foregoing, I am of the opinion that:

          (1)  The Borrower is a corporation duly incorporated, validly existing
     and in good standing under the laws of Pennsylvania, and has all corporate
     powers and all material governmental licenses, authorizations, consents and
     approvals required to carry on its business as now conducted.

          (2)  The execution, delivery and performance by the Borrower of the
     Credit Agreement is within the Borrower's corporate powers, have been duly
     authorized by all necessary corporate action, require no action by or in
     respect of, or filing with, any governmental body, agency or official and
     do not contravene, or constitute a default under, any provision of
     applicable law or regulation or of the articles of incorporation or by-laws
     of the Borrower or of any material agreement, judgment, injunction, order,
     decree or other instrument binding upon the Borrower or any of its
     Subsidiaries or result in the creation or imposition of any Lien on any
     asset of the Borrower or any of its Subsidiaries.

                                       46
<PAGE>
 
          (3)  The Credit Agreement constitutes a valid and binding agreement of
     the Borrower enforceable in accordance with its terms, except as the same
     may be limited by bankruptcy, insolvency or similar laws affecting
     creditors' rights generally and by general principles of equity.

          (4)  Except as disclosed in the Borrower's 1997 Form 10-K, in the
     Borrower's Latest Form 10-Q or in the Borrower's Schedule 14D-1 filed with
     the Securities and Exchange Commission in connection with the Offer, there
     is no action, suit or proceeding pending against, or to the best of my
     knowledge threatened against or affecting, the Borrower or any of its
     Subsidiaries before any court or arbitrator or any governmental body,
     agency or official, in which there is a reasonable possibility of an
     adverse decision which could materially adversely affect the business,
     financial position, operations or prospects of the Borrower and its
     Consolidated Subsidiaries, considered as a whole, or the ability of the
     Borrower to perform its obligations under the Credit Agreement, or which in
     any manner draws into question the validity of the Credit Agreement.

          (5)  Each of the Borrower's Significant Subsidiaries is a corporation
     validly existing and in good standing under the laws of its jurisdiction of
     incorporation, and has all corporate powers and all material governmental
     licenses, authorizations, consents and approvals required to carry on its
     business as now conducted.

                Very truly yours,

                                       47

                      ASSIGNMENT AND ASSUMPTION AGREEMENT

                         AGREEMENT dated as of _________, 19__ among [ASSIGNOR]

                    AGENT").

                              W I T N E S S E T H

          WHEREAS, this Assignment and Assumption Agreement (the "AGREEMENT")
relates to the Credit Agreement dated as of October 29, 1998 among the Borrower,
the Assignor and the other Banks party thereto, as Banks, and the Administrative
Agent (the "CREDIT AGREEMENT");

          WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans to the Borrower in an aggregate principal amount at any
time outstanding not to exceed $__________;

          WHEREAS, Loans made to the Borrower by the Assignor under the Credit

          WHEREAS, the Assignor proposes to assign to the Assignee all of the
rights of the Assignor under the Credit Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $__________ (the "ASSIGNED AMOUNT"),
together with a corresponding portion of its outstanding Loans, and the Assignee
proposes to accept assignment of such rights and assume the corresponding
obligations from the Assignor on such terms;

          NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

          Section 1.01.  Definitions.  All capitalized terms not otherwise
defined herein shall have the respective meanings set forth in the Credit
Agreement.

          Section 1.02. Assignment.  The Assignor hereby assigns and sells to

  from the Assignor of the corresponding portion of the principal amount of the
  Loans made by the Assignor outstanding at the date hereof.  Upon the execution

  and delivery hereof by the Assignor, the Assignee[, the Borrower and the
  Administrative Agent] and the payment of the amounts specified in Section 3
  required to be paid on the date hereof (i) the Assignee shall, as of the date

                                       48
<PAGE>
 
  hereof, succeed to the rights and be obligated to perform the obligations of a
  Bank under the Credit Agreement with a Commitment in an amount equal to the
  Assigned Amount, and (ii) the Commitment of the Assignor shall, as of the date

  hereof, be reduced by a like amount and the Assignor released from its
  obligations under the Credit Agreement to the extent such obligations have
  been assumed by the Assignee.  The assignment provided for herein shall be
  without recourse to the Assignor.

          Section 1.03.  Payments.  As consideration for the assignment and sale
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds the amount heretofore agreed between them.*  It is
understood that commitment and/or facility fees accrued to the date hereof are
for the account of the Assignor and such fees accruing from and including the
date hereof are for the account of the Assignee.  Each of the Assignor and the
Assignee hereby agrees that if it receives any amount under the Credit Agreement
which is for the account of the other party hereto, it shall receive the same
for the account of such other party to the extent of such other party's interest
therein and shall promptly pay the same to such other party.

          Section 1.04.  Consent of the Borrower and the Administrative Agent.
This Agreement is conditioned upon the consent of the Borrower and the

  this consent.

          Section 1.05.  Nonreliance on Assignor.  The Assignor makes no
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Borrower, or the validity and enforceability of the obligations of the Borrower
in respect of the Credit Agreement.  The Assignee acknowledges that it has,
independently and without reliance on the Assignor, and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into *Amount should combine principal together with accrued
interest and breakage compensation, if any, to be paid by the Assignee, net of
any portion of any upfront fee to be paid by the Assignor to the Assignee.  It
may be preferable in an appropriate case to specify these amounts generically or
by formula rather than as a fixed sum.  This Agreement and will continue to be
responsible for making its own independent appraisal of the business, affairs
and financial condition of the Borrower.

                     -----------------------------------------
may be signed in any number of counterparts, each of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same 
instrument. This Amendment shall become effective as of the date hereof when the
Agent shall have received:

          (a)  duly executed counterparts hereof signed by the Borrower and the 
     Banks (or, in the case of any party as to which an executed counterpart
     shall not have been received, the Agent shall have received telegraphic,
     telex or other written confirmation from such party of execution of a
     counterpart hereof by such party);

          (b)  a duly executed Note for each New Bank (a "New Note"), dated on 
     or before the date of effectiveness hereof and otherwise in compliance with
     Section 2.05 of the Agreement;

          (c)  an opinion of counsel for the Borrower, addressed to the Banks 
     and the Agent, substantially in the form of Exhibit A hereto (which the
     Borrower hereby expressly instructs such counsel to prepare and deliver);

          (d)  a certificate signed by the Chief Financial Officer of the 
     Borrower, dated the date hereof, to the effect that no Default shall have
     occurred and be continuing and that the representations and warranties of
     the Borrower contained in the Agreement, as amended hereby, shall be true
     and correct as of the date of effectiveness hereof; and

          (e)  all documents that the Agent may reasonably request relating to 
     the existence of the Borrower, the corporate authority for and validity of
     this Amendment and the New Notes, and any other matters relevant hereto,
     all in form and substance satisfactory to the Agent.

                         Employment and Pension Contract


                                     between


DLW Corporation, Bietigheim
- - hereafter referred as "the company" -
represented by the board of supervisors, in turn
represented by its chairman, Dr. Horst Burgard                  - first party -

                                       and

Dr. Bernd Pelz,
born February 11, 1944                                           -second party-


                                      (S)1


(1)  By decision of the board of supervisors on October 6, 1989, Dr. Pelz has
     been appointed to be a member of the executive board of the company,
     effective April 1, 1990. This appointment will be effective until March 31,
     1995.

(2)  Dr. Pelz promises to carry out his assigned duties in observance of the
     legal regulations, statutes, orders of the executive board, decisions of
     the board of supervisors, and this employment contract.

(3)  Dr. Pelz must devote his entire effort and time in service exclusively to
     the company and must preserve and promote the interests of the company with
     great care.

(4)  In the absence of prior written consent from the chairman of the board of
     supervisors for this company, Dr. Pelz may not undertake any business or
     professional activity (whether alone or in collaboration, compensated or
     not), participate in similar or related enterprises, or serve as a member
     of the board
<PAGE>
 
     or in any similar function for another company. The acceptance of honorary
     offices, unless required by law, also requires the approval of the chairman
     of the board of supervisors. The same also applies to publications that
     could have an adverse effect on the interests of the company.


                                      (S)2

Dr. Pelz represents the company [effective only] together with another member of
the executive board or an authorized official.


                                      (S)3


(1)  As remuneration for his service, Dr. Pelz shall receive

     a)   a fixed, gross annual salary of 220,000.00 DM, to be paid out in equal
          monthly payments over the course of the year.

     b)   in addition, Dr. Pelz shall receive a profit-based bonus for each
          percent of dividends distributed by the company for the fiscal year,
          as long as no prior claims on profits or amounts designated for
          reserves are included therein.

          The bonus amounts to

          7,000.00 DM with dividend rates up to and including 16% and 12,500.00
          DM with dividend rates over 16%

          It shall be issued at the close of the shareholders' meeting that
          deals with the handling of profits.

          The profit-based bonus is guaranteed [at a minimum of] 180,000.00 DM
          for the first two years this contract is in effect.

(2)  Travel expenses and other expenditures arising from company business are
     reimbursed separately up to the maximum amount allowed by tax laws.
<PAGE>
 
                                      (S)4


Dr. Pelz is entitled to five weeks of vacation per year. The [scheduling of]
vacation time is to be coordinated with the other members of the executive board
as well as the chairman of the board of supervisors.


                                      (S)5


(1)  Should Dr. Pelz be prevented from carrying out his duties because of
     illness or through circumstances beyond his control, he will be entitled to
     receive his salary for up to 6 months, but not beyond the end of the
     employment contract.

(2)  Should Dr. Pelz die while the contract is in force, his widow or--if she is
     no longer living--his children shall be entitled to the fixed salary, per
     (S) 3, paragraph 1 a), for the duration of three months after the month of
     his death as well as to a prorated, profit-based bonus, per (S) 3,
     paragraph 1b).


                                      (S)6


Dr. Pelz shall be obliged, upon his departure from the executive board, to make
available to the company all seats held within the supervisory board and other
offices connected with his appointment as an executive board member and, if
requested by the company, to do all he can to assist with the installation to
his position of an individual to be designated by the board of supervisors.
<PAGE>
 
                                      (S)7


(1)  Should Dr. Pelz depart from his service in the company


     a)   due to permanent disability or

     b)   after reaching age 65 or

     c)   because the company does not renew his appointment as executive board
          member after April 1, 1995 through no fault of his own,


     then Dr. Pelz shall receive a retirement pension, to be paid in equal
     monthly payments at the end of each month for the remainder of his life.
     Should the employment contract end before he reaches age 65 due to reasons
     not listed in paragraph 1 a) or c), then Dr. Pelz shall become entitled to
     his maintenance settlement, if and so far as the legal requirements for
     nonforfeitability are met.

(2)  In the event of (S) 7, paragraph 1 c), Dr. Pelz must allow any income from
     other professional endeavors to be dedected from his retirement pension, if
     the combined amount exceeds the fixed salary, as per section (S) 3,
     paragraph 1 a).

(3)  Upon reaching age 65, Dr. Pelz shall become eligible to retire.


                                      (S)8


(1)  The amount of the retirement pension is calculated on the basis of time in
     active service with the company at the moment entitlement begins. This
     amounts to 45% of the fixed annual salary as of April 1, 1990 and increases
     for each full year in service after April 1, 1990 by 1% of the fixed annual
     salary, up to a maximum of 60%. The executive bonus does not fall under the
     meaning of salary.
<PAGE>
 
(2)  Should the base salary for an unmarried federal civil servant in the B 9
     salary bracket (ministry department head), including Christmas
     bonus--however, not including salary weighting allowance or other
     remuneration and benefits of any kind--change from the amount effective at
     the beginning of the retirement payment, then at that time the retirement
     pension shall also change at the same percentage rate. [This change will
     take place] at the beginning of the month after the change in the official
     civil servant salary comes into effect.


                                      (S)9


In addition to the executive bonus for the previous fiscal year, to which Dr.
Pelz is entitled in the first year of retirement, Dr. Pelz shall also receive in
the second year of retirement 3/4 of the full bonus; in the third year, one
half; and in the fourth year, 1/4, based at the time on the previous fiscal
year.


                                      (S)10


The entitlements per (S) 7 through 9 shall cease if, after becoming eligible for
retirement, Dr. Pelz participates, without the approval of the board of
supervisors, directly or indirectly in a competing enterprise or undertakes any
activity which harms the interests of the company.


                                      (S)11


Should Dr. Pelz die during active service or after he becomes eligible to
receive his retirement pension, in the absence of grounds to revoke his
entitlement to the pension, his widow shall become entitled, notwithstanding the
stipulation of (S) 5, paragraph 2, to a widow's pension as follows:
<PAGE>
 
(1)  The widow shall become entitled to 60% of the benefits per (S) 8 and (S) 9.
     This entitlement shall cease in the event of her death or her remarriage.

(2)  Should Dr. Pelz no longer be married at the time of his death, or should
     his widow die later, each child shall receive 30% of the payments arranged
     for in (S) 8 and (S) 9; however, together the children may receive no more
     than 60% of the pension entitlement described in (S) 8.

     The orphan's pension entitlement for each child ceases at age 21. If a
     child is still a student at this time, the orphan's pension entitlement
     will be extended to the end of his/her studies, but not beyond the 25th
     birthday. The entitlement to the orphan's pension ceases likewise when the
     child marries. Should the spouse be unable to earn a shared living wage,
     then [the entitlement shall be extended] up to but not beyond the 25th
     birthday.


                                     (S)12


(1)  This contract shall remain in effect until the end of the period for which
     Dr. Pelz has been appointed a member of the executive board. It shall be
     extended--under the same terms as before--to [cover any subsequent] period
     for which Dr. Pelz, by decision of the board of supervisors at that time,
     is newly appointed as a member of the executive board. It shall cease in
     any case with the completion of the appointment.

(2)  The board of supervisors shall renew the appointment at the time not later
     than a half-year before its completion. Should the board fail to do this,
     it shall be expressing thereby that the appointment shall not be renewed.

Dear Mr. Pelz,

The executive committee of the board of supervisors has decided to amend (S) 8,
paragraph (1) of the employment and pension contract you signed on October 13,
1989, as follows:

                                    (S)8(1)

     "The amount of the retirement pension is calculated, subject to Section 3,
     on the basis of time in active service with the company at the moment
     entitlement begins. This amounts to 45% of the fixed annual salary as of
     April 1, 1990 and increases for each full year in service after April 1,

Dear Dr. Pelz,

The executive committee of the board of supervisors has decided, in light of the
financial situation of DLW AG, to leave the fixed salary for the board unchanged
for 1997. However, the executive bonus plan, which up to now has been purely
dividend-based, will be replaced. Because the old plan made payment of special,
partial bonuses necessary, due to low or no dividend payments by DLW AG in past
years, it will be replaced with a new plan which makes possible a variable
remuneration based upon results and projects in the individual areas of
responsibility. By standardizing the relationship between projected bonus and
fixed salary at a 5 to 8 ratio, the new executive bonus plan is tied to an
increase in your total salary (if projections are met) to 634,000.00 DM in 1997.

The executive committee is convinced that, with the following changes in your
employment contract, the basis for a transparent, results-based and fully
adaptable remuneration system will result.

                                    (S)3(1)

     "As remuneration for his work, Dr. Pelz shall receive

     a)   a fixed, gross annual salary of 390,000.00 DM, which is to be paid out
          in equal monthly payments over the course of the year;

     b)   a results-based, annual bonus, the amount of which is to be based upon
          the plan to be drawn up at the beginning of the fiscal year. This
          bonus shall be calculated from the results and projects for which Dr.
          Pelz is responsible as well as from the shared results of
<PAGE>
 
          the combined corporation, which are included in the planning. If
          projections are met, the bonus should amount to 244,000.00 DM. The
          bonus will be issued at the close of the regular shareholders' meeting
          at the end of the fiscal year."

For the year 1997, your bonus shall be calculated according to a plan, which was
already discussed with you and which is detailed in the enclosed document. On a
related matter, I would be grateful if you could provide me with an overview of
the basic distribution among the different corporate divisions as well as the
central division.

Please confirm on the enclosed copy of the letter your acceptance of the change
in the contract and the bonus plan for the year 1997.

I hope you have a nice Christmas, a good start in 1997 and continued success
with DLW.

                                                 Sincerely,

                                                 [signature]

I accept:
ref. Letter Dr. Breuer dated 1-21-97
Bietigheim-Bissingen, dated 1-23-97                        [signature]
                                                           (Dr. Bernd F. Pelz)
<PAGE>
 
Dr. Breuer's letter dated January 6, 1998:

Dear Dr. Pelz,

I am pleased to be able to tell you that the Presidential Committee of the DLW
Supervisory Board has decided effective January 1, 1998 to raise your fixed
salary to DM 415,000 - and to have the variable part of your total income
constitute 40% of your total salary, provided plans are met.

For 1998 the committee suggests that the variable income be dependent upon
following performance criteria:

                                               % of variable income

Return on gross sales DLW Group                33.3 %
Return on equity DLW AG                        33.3 %
Return on gross sales floorings                16.7 %
Return on assets floorings                     16.7 %

The weight of the individual criteria reflects your responsibility for the total
DLW Group as Chairman of the Management Board and also considering your special
responsibility for the floor covering division. In addition to this we intend to
base the bonus payments on your proposal dated November 26, 1997 in regard to
the variability and the band width.

Concerning 1997 the auditors of DLW AG will determine the relevant values upon
which your bonus payments for 1997 will be based.

The raise in your compensation is an appreciation of your services to the
company and the expectation that you will continue to bond a sustainable
profitability of DLW AG.

Please confirm with your signature that you accept the bonus scheme for 1998 and
return the relevant document.

With our best wishes for a successful business in the coming new year. 

Dr. Rolf-E. Breuer

                       --------------------------------

                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.

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.
<PAGE>
 
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%.

     E)   The incentive award determined in accordance with the provisions of
          Paragraphs A through D of this Section 4 shall be reduced for such
          year as follows for Plan participants who are eligible to participate
          in the Bonus Replacement Retirement Plan of Armstrong World
          Industries, Inc.:

            (1)  If a Plan participant's grade level is at least 1200 but not
                 higher than 1459 as of January 1 of the calendar year for which
                 the incentive award is determined, the incentive award
                 otherwise payable shall be reduced by the lesser of (i) 50% of
                 the amount determined under Paragraphs A through D, (ii) $7,500
                 or (iii) the authorized contribution to the Bonus Replacement
                 Retirement Plan.

            (2)  If a Plan participant's grade level is at least 1460 but not
                 higher than 1929 as of January 1 of the calendar year for which
                 the incentive award is determined, the

          (i) 50% of the amount determined under Paragraphs A through D, (ii)
          $15,000 or (iii) the authorized contribution to the Bonus Replacement
          Retirement Plan.

     (3)  If a Plan participant's grade level is at least 1930 as of January 1
          of the calendar year for which the incentive award is determined, the
          incentive award otherwise payable shall be reduced by the lesser of

          Retirement Plan.

       other than cause on or after the last workday of March may be eligible
       for awards on a prorated basis.

          to benefits under the Retirement Income Plan; provided, however, that
          the benefit under Section 3.01(a)(iii) hereof shall not be payable
          (and the offset under Section 3.01(c) hereof shall not be applied)
          with respect to a Member described in Section 2.02(d) unless following
          his date of hire with the Company the Member remains employed by the
          Company for a period of at least 5 full years.  Any such supplemental
          benefits shall be payable from the general assets of the Company or
          from a trust, if any, established by the Company for the purpose of
          paying benefits under the Plan, the assets of which shall remain
          subject to the claims of judgment creditors of the Company in
          accordance with the provisions of any such trust.  The supplemental
          benefits under this Plan shall be payable under the same terms and
          conditions, including the same time, and to the same person as the
          benefits payable to or on account of a Member under the Retirement
          Income Plan.

          The amount of any supplemental benefits payable to or on account of a
          Member pursuant to this Plan shall be equal to (a) minus (b) minus
          (c), where:

          (a)  is the benefit calculated under the provisions of the Retirement
               Income Plan, but:

               (i)   disregarding any reduction in the amount of benefits under
                     the Retirement Income Plan attributable to any provision
                     therein incorporating limitations imposed by Section 415 of
                     the Internal Revenue Code or Section 401(a)(17) of the
                     Internal Revenue Code;

               (ii)  disregarding any reduction due to compensation deferred
                     under the Armstrong Deferred Compensation Plan;

               (iii) including, for purposes of calculating Total Service under
                     the Retirement Income Plan, years of employment for a
                     Member described in Section 2.02(d) which precede his
                     Company employment to the extent so designated by the Board
                     of Directors, or its delegate, at the time such individual
                     is designated as eligible for membership in the Plan;


               (iv)  including, for purposes of determining compensation, any
                     amounts contributed on a Member's behalf to the Bonus
                     Replacement Plan.

          (b)  is the actual amount of benefits payable to or on account of the
               Member as calculated under the Retirement Income Plan; and

          (c)  is the value of the benefit (excluding the portion of such
               benefit attributable to employee contributions) which is payable,
               which has been paid or which will become payable to a Member
               described in Section 2.02(d) from a qualified defined benefit
               plan to the extent such plan takes into account the period of
               employment described in Section 3.01(a)(iii).  In the event the
               Member has received, is receiving, or is scheduled to receive
               benefits from another such plan in any form other than a single
               life annuity or at a time other than when benefits commence under
               this Plan, the benefit to be taken into account under this

                                       2
<PAGE>
 
               paragraph (c) shall be determined by the Company based on
               actuarial assumptions and factors reasonably utilized under the
               Retirement Income Plan as of the date of determination, or to the
               extent such factors or assumptions do not contemplate a
               particular situation which arises under this Plan, based upon the
               factors applied by the Pension Benefit Guaranty Corporation for
               purposes of determining the present value of benefit upon
               termination of a plan with insufficient assets.

          Notwithstanding the preceding provisions of this Section 3.01, in the
          event a retired or terminated Member's benefit calculated under the
          Retirement Income Plan is increased for any reason after the Member's
          supplemental benefit payments have commenced, the amount of any
          supplemental benefits payable to or on account of such Member under
          this Plan shall be reduced correspondingly on a prospective basis, and
          in the event such increase is made retroactively resulting in
          overpayments of the Member's supplemental benefits, future benefit
          payments under this Plan shall be reduced to reflect such prior
          overpayments in any manner determined by the Committee, in its
          discretion, and applied on a consistent basis to all similarly
          situated Members, until an amount equal to the total overpayments in
          the Member's supplemental benefit payments are recovered.

     3.02 If a Member described in Section 2.02 (d) is involuntarily terminated
          after completing one year of service but prior to becoming vested in
          the Retirement Income Plan and who receives severance pay benefits
          under the Severance Pay Plan for Salaried Employees of Armstrong World
          Industries, Inc. or any individual severance agreement, or who is
          eligible for severance pay benefits under the Employment Protection
          Plan for Salaried Employees of Armstrong World Industries, Inc., a
          supplemental benefit will be paid under this Plan.  The benefit will
          be calculated using the guaranteed pension schedule for Salaried
          Employees of Armstrong World Industries, Inc., from the Retirement
          Income Plan multiplied by the total years of service credited for
          employment prior to his Company employment, as determined in Section
          2.02(d) and his years of Company employment.  This benefit is payable
          at age 62 or the Member's termination date, whichever is later, as a
          single life annuity.

     3.03 If a Member is restored to employment with the Company after having
          retired, any monthly payments under the Plan shall be discontinued
          and, upon subsequent retirement or termination of employment with the
          Company, the Member's benefits under the Plan shall be recomputed in
          accordance with Section 3.01 and shall again become payable to such
          Member in accordance with the provisions of the Plan.

Article 4.  Administration

     4.01 The administration of the Plan and the responsibility for carrying out
          its provisions are vested in a Retirement Committee which shall be
          composed of the members of the Retirement Committee provided for under
          Article X of the Retirement Income Plan.  The provisions of Article X
          of the Retirement Income Plan concerning powers of the Committee shall
          apply under this Plan.  The Retirement Committee shall have the full
          and exclusive discretion and authority to interpret the Plan and to
          determine all benefits and to resolve all questions arising from the
          administration, interpretation, and application of Plan provisions,
          either by general rules or by particular decisions, including
          determinations as to whether a claimant is eligible for benefits, the
          amount, form and timing of benefits, and any other matter (including
          any question of fact) raised by a claimant or identified by the
          Retirement Committee.  All decisions of the Committee shall be
          conclusive and binding upon all affected persons.  The expenses of the
          Committee shall be paid directly by the Company.

Article 5.  General Provisions

     5.01 The establishment of the Plan shall not be construed as conferring any
          legal rights upon any person for a continuation of employment, nor
          shall it interfere with the rights of the Company to discharge any
          employee and to treat him without regard to the effect which such
          treatment might have upon him as a Member of the Plan.  No legal or
          beneficial interest in any of the Company's assets is intended to be
          conferred by the terms of the Plan.

                                       3
<PAGE>
 
     5.02 In the event that the Committee shall find that a Member or other
          person entitled to benefits hereunder is unable to care for his
          affairs because of illness or accident, the Committee may direct that
          any benefit payment due him, unless claim shall have been made
          therefor by a duly appointed legal representative, be paid to his
          spouse, a child, a parent or other blood relative, or to a person with
          whom he resides, and any such payment so made shall be a complete
          discharge of the liabilities of the Company and the Plan therefor.

     5.03 The Company shall have the right to deduct from each payment to be
          made under the Plan any required withholding taxes.

     5.04 Subject to any applicable law, no benefit under the Plan shall be
          subject in any manner to anticipation, alienation, sale, transfer,
          assignment, pledge, encumbrance or charge, any attempt so to do shall
          be void, nor shall any such benefit be in any manner liable for or
          subject to garnishment, attachment, execution or levy, or liable for
          or subject to the debts, contracts, liabilities, engagements or torts
          of the Member.  In the event that the Committee shall find that any
          Member or other person entitled to benefits hereunder has become
          bankrupt or has made any such attempt with respect to any such
          benefit, such benefit shall cease and terminate, and in that event the
          Board shall hold or apply the same to or for the benefit of such
          Member or other person entitled to benefits.

     5.05 (a)  In the event that a Member shall at any time be convicted of a
               crime involving dishonesty or fraud on the part of such Member in
               his relationship with the Company, all benefits which would
               otherwise be payable to him under the Plan shall be forfeited.
               Notwithstanding the foregoing, if the Company's Board of
               Directors or a duly constituted Committee thereof, in its
               discretion, shall determine that the Member had no reasonable
               cause to believe his conduct was unlawful, then the Board of
               Directors may determine that such benefits shall not be
               forfeited.

          (b)  In the event that a Member becomes associated in any capacity
               with a business which competes with the Company, all future
               benefit payments under the Plan shall cease and be forfeited.
               Notwithstanding the foregoing, benefits shall not cease or be
               forfeited merely because the Member (1) owns publicly traded
               shares of stock of a corporation which competes with the Company,
               or (2)(a) acts as a consultant for, (b) has an investment in, or
               (c) is a Board member of a business where (i) after the Member
               notifies the Company in writing in advance of his potential
               involvement under (2)(a), (b) or (c), the Company's Board of
               Directors or a duly constituted Committee thereof determines that
               the Member will not be in violation of the Company's Conflicts of
               Interest policy, or (3) becomes associated with a business which
               competes with the Company within two years following a "change in
               control" and is eligible for benefits under the Employment
               Protection Plan for Salaried Employees.

          (c)  A "change in control" shall occur if and when (i) any person
               acquires "beneficial ownership" of more than 28% of the then
               outstanding "voting stock" of the Company and within five years
               thereafter, "disinterested directors" no longer constitute at
               least a majority of the entire Board of Directors or (ii) there
               shall occur a "business combination" with an "interested
               shareholder."  For the purpose of this Section, the terms
               "person," "beneficial ownership," "voting stock," "disinterested
               director," "business combination," and "interested shareholder"
               shall have the meaning given to them in Article 7 of the
               Company's Articles of Incorporation as in effect on May 1, 1985.

     5.06 The Plan shall be constructed, regulated and administered under the
          laws of the Commonwealth of Pennsylvania.

     5.07 The masculine pronoun shall mean the feminine wherever appropriate.

     5.08 The Board of Directors may, through written resolutions adopted by the
          Board of Directors, amend or discontinue the Retirement Benefit Equity
          Plan at any time; provided, however, that if the Plan is 

                                       4
<PAGE>
 
          amended to discontinue or reduce the amount of supplemental benefit
          payments (except as may be required pursuant to any plan arising from
          insolvency or bankruptcy proceedings) (1) Members who have retired
          under the Plan shall continue to be paid in the amount and manner (as
          provided under Article 3 hereof) as they were being paid at the time
          of amendment or discontinuance of the Plan, and (2) future retirees
          under the Plan for whom supplemental benefits have been pre-funded in
          a trust prior to any such discontinuance or reduction in benefits,
          shall notwithstanding the amendment be entitled upon retirement to
          receive such pre-funded supplemental benefits, subject, however, to
          any amendment or discontinuation of such pre-funded benefits made
          under a written employment agreement entered into between the
          Executive Committee and the future retiree.

          In addition, the Board of Directors may by written resolution delegate
          to the Executive Committee of the Board of Directors this authority to
          amend the Plan.  The Executive Committee shall amend the Plan by means
          of written resolution in accordance with the authorization of the
          Board of Directors, provided, however, that any such amendment by the
          Executive Committee also may be made through the terms of a written
          employment agreement entered into between a Member and the Executive
          Committee.

     5.09 (a)  Any person claiming a benefit, requesting an interpretation or
               ruling under the Plan, or requesting information under the Plan
               shall present the request in writing to the Committee which shall
               respond in writing as soon as practicable.

          (b)  If the claim or request is denied, the written notice of denial
               shall state:


               (i)   The reasons for denial, with specific reference to the Plan
                     provisions on which the denial is based.

               (ii)  A description of any additional material or information
                     required and an explanation of why it is necessary.

               (iii) An explanation of the Plan's claim review procedure.

          (c)  Any person whose claim or request is denied or who has not
               received a response within thirty (30) days may request review by
               notice given in writing to the Committee.  The claim or request
               shall be reviewed by the Committee who may, but shall not be
               required to, grant the claimant a hearing.  On review, the
               claimant may have representation, examine pertinent documents,
               and submit issues and comments in writing.

          (d)  The decision on review shall normally be made within sixty (60)
               days.  If an extension of time is required for a hearing or other
               special circumstances, the claimant shall be notified and the
               time limit shall be one hundred twenty (120) days.  The decision
               shall be in writing and shall state the reasons and the relevant
               Plan provisions.  All decisions on review shall be final and bind
               all parties concerned.

     The Armstrong Deferred Compensation Plan (the "Plan") has been authorized
by the Board of Directors of Armstrong World Industries, Inc. to be effective on

employees of the Company to defer receipt of a portion of their Compensation
and, as a result, to receive certain supplemental retirement or survivor
benefits.  In addition, effective January 1, 1996, certain directors were
required to defer receipt of a portion of their Compensation until termination
of Board service.  The Plan has been amended and restated as of September 21,

          (b)    Interest credited on each such deferral for the following      
     period:

                 (i)   From the date on which the deferred Compensation normally

                       (A) For purposes of determining a Participant's
               Supplemental Retirement Account Balance, each Participant's Cash
               Subaccount shall be credited with interest at a rate equal to the
               rate which would be payable if the Participant were eligible for
               a supplemental retirement benefit pursuant to Section 4.01,
               compounded monthly.

                       (B) For purposes of determining a Participant's

               annum compounded monthly.

     1.10   "STOCK SUBACCOUNT" at any date shall mean with respect to any
Participant the amount which a Participant elects to defer and have credited to
his Stock Subaccount in accordance with subsection 3.02(h) of this Plan or, in
the case of a nonemployee director Participant, the share awards made by the
Company which the Participant defers in accordance with subsection 3.02(j), plus
any amounts the Participant elects to transfer to this Subaccount from the Cash
Subaccount or the Fund Subaccount in accordance with the provisions of Section
3.02(i), reduced by any amounts which are transferred from this Subaccount to
the Cash Subaccount or the Fund Subaccount.  A bookkeeping entry shall be made
of the number of whole and fractional shares of Company common stock that were
awarded or that could have been purchased with the amounts actually deferred
under or transferred to the Stock Subaccount by the Participant, based on the
fair market value of such stock on the date the deferral is made or the transfer
is credited to the Participant's Stock Subaccount.  The Stock Subaccount also
shall be credited with a bookkeeping entry indicating the number of additional
whole or fractional shares which would be payable as a 
<PAGE>
 
stock dividend on the shares previously credited to the Stock Subaccount. Any
amounts which would represent cash dividends on Company common stock credited to
a Participant's Stock Subaccount shall be converted to an entry representing the
number of additional shares of Company common stock which could be purchased at
fair market value with such dividends as of the date such dividends are credited
to the Subaccount.

     For purposes of this section, "fair market value" of a share of Company
common stock shall mean the closing price of a single share of Company common
stock as reported by the New York Stock Exchange on the applicable date or, if
no sales were made on such date, on the next preceding date on which sales of
the Company common stock were made.  The "applicable date" for deferred amounts
shall be the date on which the deferred Compensation would have been paid.  The
"applicable date" for transfers to or from the Stock Subaccount shall be the
effective date of the Participant's conversion election under Section 3.02(i).

     In the event of any changes in the outstanding shares of Company common
stock by reason of stock dividends, stock splits, recapitalizations,
reorganizations, mergers, consolidations, combinations, exchanges, or other
relevant changes in capitalization occurring after the date of deferral, the
Committee shall adjust the balance in the Participant's Stock Subaccount
appropriately to reflect such change.

     1.11   "FUND SUBACCOUNT" at any date shall mean with respect to any
Participant the amount which a Participant elects to defer and have credited to
his Fund Subaccount in accordance with subsection 3.02(h) of this Plan, plus any
amounts the Participant elects to transfer to this Subaccount from the Cash
Subaccount or the Stock Subaccount in accordance with the provisions of Section
3.02(i), reduced by any amounts which are transferred from this Subaccount to
the Cash Subaccount or the Stock Subaccount.  The Participant shall designate
his preference for the investment of the funds deferred by him under this
Subaccount.  Such designation shall be limited to the selection of one or more
investment funds designated on the Participant's Deferral Election forms for the
period in question.  The Company and the Trustee, if a trust is funded, may
elect to invest trust assets in such designated investment funds, but shall not
be required to do so.  In any event, the Participant's Fund Subaccount shall be
credited with the hypothetical earnings, gains, losses, and changes in the fair
market value of such Fund Subaccount for the time period that a Participant has
amounts credited to the Fund Subaccount as if the Company had followed such
investment designation (such amount being referred to herein as the
"hypothetical earnings").  A bookkeeping entry shall be made of the amounts
deferred or transferred to the Fund Subaccount, along with the hypothetical
earnings on such amounts for each investment fund selected by the Participant.
<PAGE>
 
     Deferrals credited to the Fund Subaccount under the Plan may be deemed to
be invested in one or more investment funds as approved by the Committee,
including but not limited to the following:

            (a) Equity Investment Fund - One or more diversified equity funds
                ----------------------                                       
     invested in equity securities or securities convertible into equity
     securities.

            (b) Fixed Income Investment Fund - One or more fixed income funds
                ----------------------------                                 
     invested in, but not limited to, guaranteed income contracts, bonds, notes,
     debentures, asset-backed securities and fixed income derivatives.

            (c) Money Market Fund - One or more money market funds invested in
                -----------------                                             
     short-term obligations of the United States Government, bank certificates
     of deposit, commercial paper, bankers' acceptances, shares of money market
     mutual funds and other similar types of short-term investments.

            (d) Balanced Fund - One or more balanced funds, as may be available
                -------------                                                  
     from time to time, that invest in a mixture of bonds, equities, and short-
     term instruments.

     Dividends, interest and other distributions which would otherwise be
received in respect to each hypothetical investment under the Fund Subaccount
shall be deemed to be reinvested in the respective investment fund.

2.   ELIGIBILITY FOR PARTICIPATION

     Participation in the Plan is limited to nonemployee directors of the
Company and those management employees who have been selected for participation
by the Committee.

3.   DEFERRAL OF COMPENSATION

     3.01   DEFERRAL PERIOD:  During such period or periods as may, from time to
time, be selected by the Committee (the "Deferral Period") each person eligible
to participate in the Plan shall be given the opportunity to elect to defer a
portion of his or her Compensation.  The length of the initial Deferral Period
shall be four (4) years, commencing on January 1, 1986.

     3.02   DEFERRAL RULES:

            (a) There shall be no minimum amount a Participant is required to
     defer.
<PAGE>
 
            (b) The maximum amount an employee Participant may defer for each
     year of the Deferral Period shall be twenty percent (20%) of the
     Participant's annual base salary at the time of the deferral election and
     one hundred percent (100%) of the Participant's actual bonus payable under
     the Company's annual bonus plan; or, with the approval of the Board of
     Directors, up to the sum of twenty percent (20%) of the Participant's
     annual base salary and one hundred percent (100%) of the Participant's
     target bonus award.  The amount of any bonus deferral may not exceed the
     gross amount of the bonus reduced by any tax required to be withheld from
     such amounts under Code Sections 3111(a) and (b) or any state or local
     statute.  Subject to the above deferral limitations, the Board of Directors
     may also approve deferrals from any payment of cash compensation to the
     employee Participant.  The maximum amount of Compensation deferred by a
     nonemployee director shall be determined by the director.

            (c) The amount deferred by an employee Participant shall be deferred
     by means of reductions in the employee's annual base salary or bonus,
     whichever is applicable under the Participant's deferral election.  Amounts
     deferred by a nonemployee director shall be made from the director's
     retainer fees, meeting fees and special assignment fees, and share awards
     made by the Company to the director's Stock Subaccount under Section
     3.02(j).

            (d) The decision by a Participant to defer a portion of Compensation
     (other than share awards to nonemployee directors under Section 3.02(j)) is
     an election for the full Deferral Period which must be made by the December
     1 prior to the Deferral Period to which an election to defer Compensation
     relates; provided, however, that in the case of a Participant whose
     eligibility to participate in the Plan initially commences after January 1
     of a year, a decision to defer a portion of Compensation earned after such
     a deferral election and during the remaining part of a Deferral Period must
     be made no later than thirty (30) days after the Participant's commencement
     of participation.

            The decision by a Participant of the amount to be deferred under
     this Plan for each calendar year in the Deferral Period (other than share
     awards to nonemployee directors under Section 3.02(j)) is an annual
     election which must be made by December 1 of the calendar year prior to the
     year in which the amount is to be deferred.

            Deferrals of share awards to nonemployee directors under Section
     3.02(j) shall be automatic at the time such award is made and shall not
     require a deferral election other than the initial election described in
     Section 3.02(j) for Participants who were directors prior to January 1,
     1996.
<PAGE>
 
            (e) Except as provided below and in Section 3.02(f), a Participant's
     election to defer Compensation shall be irrevocable for the Deferral Period
     and a Participant's election of the amount to be deferred shall be
     irrevocable for the calendar year in which the election is effective.
     Notwithstanding the prior sentence, the Committee may permit a Participant
     to waive the remainder of the deferral commitment upon a finding based upon
     uniform standards established by the Committee that the Participant has
     suffered a severe financial hardship.

            For these purposes, a severe financial hardship includes a sudden
     and unexpected illness or accident of the Participant or a dependent (as
     defined under Section 152(a) of the Internal Revenue Code of 1986, as
     amended), loss of the Participant's property due to casualty, or other
     similar extraordinary and unforeseeable circumstances arising as a result
     of events beyond the control of the Participant, to the extent not
     reimbursed by insurance or otherwise, and to the extent the Participant
     does not have other funds reasonably available to alleviate the hardship.

            (f) Any Participant receiving a supplemental retirement benefit
     under Section 4 shall forfeit his or her right to make further deferrals
     under the Plan.

            (g) Notwithstanding the above or Section 3.02(f), any Participant,
     after approval of the Committee, may elect to complete the deferral of
     annual base salary as specified in the current Deferral Election from any
     "severance pay" which the employee is eligible to receive under the
     Employment Protection Plan for Salaried Employees, the Severance Pay Plan
     for Salaried Employees or any individual agreement following the date of
     termination.

            (h)  At the time a Participant makes an election for the amount to
     be deferred for a calendar year during the Deferral Period in accordance
     with this Section 3.02, such Participant may elect in writing that a
     specified percentage (stated in five percent (5%) increments) of the
     Compensation he is deferring pursuant to the Plan for such calendar year be
     credited to his Cash Subaccount, to his Stock Subaccount or to the
     individual investment funds elected by the Participant in his Fund
     Subaccount.  Such percentage allocation may be changed with respect to
     future deferrals at any time.  If the Participant's election fails to
     specify the percentage to be allocated to each Subaccount or allocates less
     than one hundred percent (100%) of the amounts to be deferred, the amounts
     deferred by the Participant for which no allocation election has been made
     for the calendar year shall be credited to the Participant's Cash
     Subaccount.
<PAGE>
 
            (i) At any time, a Participant may elect to convert all or a portion
     of amounts previously deferred under one Subaccount to any other
     Subaccount; provided, however, that amounts deferred or otherwise credited
     to the Stock Subaccount may not be converted to the Cash Subaccount or the
     Fund Subaccount if the Participant is a reporting person subject to the
     provisions of Section 16(a) of the Securities Exchange Act of 1934, as
     amended (the "Act").  For purposes of this Plan, a person shall be deemed
     to be a reporting person subject to Section 16(a) of the Act for the period
     he is such a reporting person and six (6) months thereafter.  The
     Participant's election shall be effective on the first day of the month
     following the receipt of such election by the Secretary of the Committee,
     provided that the Secretary is notified of such election by the twenty-
     fifth (25th) day of the month prior to the conversion date.  Notice by
     telephone or facsimile shall be deemed to constitute notice to the
     Secretary of the conversion election, provided that a written form is
     submitted immediately subsequent to such notice.  The number of shares to
     be credited to a Participant's Stock Subaccount, or the number of shares to
     be debited from a Participant's Stock Subaccount and the cash to be
     credited to the Participant's Cash Subaccount, or an investment fund in the
     Fund Subaccount, shall be based on the fair market value of Company common
     stock (as determined in Section 1.10 of the Plan) on the date that the
     conversion election is effective.  The interest rates for amounts
     transferred to the Cash Subaccount shall be the rates in effect under
     Section 1.09(b)(ii) for deferrals made during the Deferral Period in which
     the conversion election is effective.  Hypothetical earnings credited on
     amounts transferred to the Fund Subaccount shall be based on the actual
     investment performance of each applicable investment fund for the time
     period that a Participant has an account balance in such investment funds.

            (j) Effective January 1, 1996, nonemployee directors of the Company
     who were members of the Board prior to January 1, 1996, were able to elect
     to discontinue their participation in the Directors' Retirement Income Plan
     ("Directors' Plan") and waive their right to any benefit accrued under the
     Directors' Plan.  If a nonemployee director made this election, such
     director became eligible to receive an annual award equivalent to the value
     of two hundred (200) shares of Company common stock which shall be credited
     to his Stock Subaccount.  The annual share award shall be made each January
     1 up until the time a director attains twelve (12) years of Board service,
     including years of Board service prior to January 1, 1996.  The first such
     award was made on January 1, 1996.  Further, such director received,
     effective January 1, 1996, a share award grant to replace the value of the
     accrued Directors' Retirement Income Plan benefit the director elected to
     forfeit.  This share award grant was credited to the director's Stock
     Subaccount and was the greater of:
<PAGE>
 
                        (i)  Two hundred (200) shares times the number of full
                 years of Board service as of January 1, 1996, up to a maximum
                 of twelve (12) years, or
               
                        (ii) The number of shares whose value (based on the fair
                 market value of Armstrong common stock on January 1, 1996)
                 equated to the present value of the benefits accrued under the
                 Directors' Retirement Income Plan using a six and one half
                 percent (6.5%) discount rate and assuming benefit payments
                 commence on the first day of the month following the director's
                 sixty-fifth (65th) birthday (January 1, 1996, if the director
                 was older than sixty-five (65)).

                 Nonemployee directors who join the Board after January 1, 1996,
          shall be eligible to receive an annual award equivalent to two hundred
          (200) shares of Armstrong common stock which shall be credited to
          their Stock Subaccount unless the director elects to receive stock
          options in lieu of this award.  The annual share award shall be made
          each January 1 until such time as a director attains twelve (12) years
          of Board service.

          3.03   Manner of Electing Deferral and Payment of Benefits: A
Participant shall elect to defer Compensation by giving written notice to the
Company on forms provided for such purposes, which notice shall include:

                 (a) The amount and manner of Compensation to be deferred in
     each calendar year of a specified Deferral Period. An employee Participant
     shall make a separate election for amounts of annual base salary to be
     deferred and amounts of bonus awards to be deferred.

                 (b)  A Designation of Beneficiary.

                 (c) The date of commencement of payment of deferred
     Compensation and interest thereon, subject to the limitations of Section
     4.04.

                 (d) The designation of the Subaccount (Cash, Stock or Fund and,
     if applicable, the investment fund or funds under the Fund Subaccount) to
     which deferrals are to be credited for each calendar year of the specified
     Deferral Period.

     The Designation of the Beneficiary shall continue to be effective until and
unless a new election is filed in writing with the Committee.  The designation
of the date of commencement of benefits shall be irrevocable, except as provided
in Section 4.04.
<PAGE>
 
4.   PAYMENT AND AMOUNT OF BENEFITS

     4.01   A Participant who, in the case of a nonemployee director, ceases to
be a director following one (1) year of service on the Board of Directors for
any reason other than death or, in the case of an employee, who retires under
any Company Pension Plan, shall be entitled to receive from the Company
supplemental retirement benefits as specified in the Participation Agreement or
in any amendment thereto or as otherwise agreed upon between the Company and the
Participant pursuant to an early retirement opportunity.  The normal payment
period for nonemployee directors shall be one hundred twenty (120) months; for
employees, one hundred eighty (180) months, provided however that alternative
payment schedules may be established by the Management Development and
Compensation Committee of the Board of Directors.

     4.02   The supplemental retirement benefit for a Deferral Period will be
paid, but in a lesser amount, if:

            (a) By the end of a Deferral Period the Compensation payable to a
     Participant has proved insufficient to accommodate full deferral;

            (b) Prior to the end of a Deferral Period, a nonemployee director
     ceases to be a director after completing one (1) year of service on the
     Board of Directors for any reason other than death;

            (c) A Participant ceases to be a Participant within a Deferral
     Period because his or her employment with the Company ceases or such
     Participant retires under any Company Pension Plan within that period;

            (d) A Participant discontinues deferrals due to severe financial
     hardship.

     4.03   If a Participant dies after the commencement of supplemental
retirement benefit payments but before receipt of the last payment, the
remaining amounts shall be paid, on their respective due dates, to the
Participant's beneficiary designated in the Beneficiary Designation Form
provided for such purpose or, failing such designation, to the Participant's
estate.

     4.04   Payment of all benefits under this Plan shall commence in accordance
with the election made by the Participant pursuant to Section 3.03, provided,
however, that:

            (a) For a Participant who is a nonemployee director, payment may
     commence at any time following termination of service as a director, but in
     no event earlier than age sixty-five (65) for directors who begin Plan
     participation before January 1, 1996; provided that payments never will
     
<PAGE>
 
     commence later than the first day of the month following the Participant's
     seventieth (70th) birthday, regardless of whether service as a director has
     terminated at that time.

            (b) For a Participant who is an employee, payment shall commence at
     any time subsequent to retirement; provided, however, that payment will
     commence in all events not later than the first day of the month following
     such Participant's sixty-fifth (65th) birthday regardless of whether the
     Participant has actually retired at that time.

            The Company reserves the right to impose conditions, including with
     respect to payment commencement, in connection with early retirement
     opportunities or any other severance arrangements which otherwise enhance
     an employee Participant's retirement income.

            Subject to the concurrence of the Committee, a Participant may
     change such election to commence the receipt of supplemental retirement
     benefits to an otherwise permissible date earlier than the date the
     Participant had elected previously for the commencement of such benefits,
     provided that such change occurs at least one (1) year prior to the
     calendar year in which such payments are to commence and provided further
     that no distribution from the Stock Subaccount shall be made to a
     Participant who is a reporting person subject to the provisions of Section
     16(a) of the Act prior to the Participant's disability or termination of
     employment or, in the case of a nonemployee director, termination of
     service.

     4.05   Notwithstanding anything hereinbefore to the contrary, if an
employee Participant resigns without the written approval of the Committee or if
a Participant who is a nonemployee director terminates service on the Board of
Directors prior to the completion of one (1) year of service, then in lieu of
the supplemental retirement benefit there shall be paid to the Participant a
lump sum, as soon as practical following termination, in an amount equal to the
Participant's Termination Account Balance.

     4.06   Notwithstanding Section 4.05, an employee Participant shall be
entitled to the supplemental retirement benefit if such Participant is
terminated, or terminates for good reason as set forth in the Employment
Protection Plan for Salaried Employees or an individual agreement, within two
(2) years following a "Change in Control."  In the event of such termination or
termination for good reason, or in the event an employee retires pursuant to an
early retirement opportunity or any other severance arrangement in which the
Participant agrees to commence payment of the supplemental retirement benefit
following the Participant's sixty-fifth (65th) birthday and a "Change in
Control" precedes commencement of such payments, the Participant shall have the
option to be paid a lump sum amount equal to his Supplemental Retirement Account
<PAGE>
 
Balance, less a penalty of six percent (6%) of such amount.  If, however, the
termination shall be in connection with a conviction or admission of dishonesty
or fraud, then such Participant shall only be entitled to the benefit described
in Section 4.05.

     4.07   Notwithstanding any other provision of the Plan, a Participant at
any time shall be entitled to receive, upon written request to the Committee, a
lump-sum distribution of the entire amount owed to the Participant under the
Plan subject to penalties determined by the Participant's status in the Plan as
set forth below; provided, however, that a Participant who is a reporting person
subject to the provisions of Section 16(a) of the Act shall not be entitled to
receive a distribution of the amount owed to the Participant under the Stock
Subaccount prior to the Participant's disability or termination of employment
or, in the case of a nonemployee director, termination of service.

            (a) For a Participant who is a current employee but ineligible to
     retire under the Retirement Income Plan, or for a Participant who is a
     nonemployee director with less than one (1) year of service, the lump-sum
     distribution will be equal to ninety percent (90%) of the Participant's
     Termination Account Balance; provided, however, that if a Participant is a
     reporting person subject to the provisions of Section 16(a) of the Act, the
     distribution shall be limited to ninety percent (90%) of the Participant's
     Termination Account Balance credited to the Cash Subaccount and the Fund
     Subaccount thereunder.

            (b) For a Participant who is a current employee eligible to retire
     under the Retirement Income Plan, the lump-sum distribution will be equal
     to the lesser of:

                (i)  Ninety percent (90%) of the Participant's Supplemental
     Retirement Account Balance; or

                (ii) the Participant's Termination Account Balance; provided,
     however, that if a Participant is a reporting person subject to the
     provisions of Section 16(a) of the Act, the distribution shall be limited
     to the lesser of:

                (A)  Ninety percent (90%) of the Participant's Supplemental
     Retirement Account Balance credited to the Cash Subaccount and the Fund
     Subaccount thereunder; or

                (B)  The Participant's Termination Account Balance credited to
     the Cash Subaccount and the Fund Subaccount thereunder.
<PAGE>
 
            (c) For a Participant who is a current nonemployee director with at
     least one (1) year of service, the lump-sum distribution will be equal to
     ninety percent (90%) of the Participant's Supplemental Retirement Account
     Balance; provided, however, that if a Participant is a reporting person
     subject to the provisions of Section 16(a) of the Act, the distribution
     will be equal to ninety percent (90%) of the Participant's Supplemental
     Retirement Account Balance credited to the Cash Subaccount and the Fund
     Subaccount thereunder.

            (d) For a Participant who is an employee or a nonemployee director
     who has terminated service with the Company and has either commenced
     installment payments or is entitled to such payments in the future, the
     lump-sum distribution will be equal to ninety percent (90%) of the
     Participant's Supplemental Retirement Account Balance.

     The remaining balance of the portion of such Participant's Subaccount(s)
from which a payment has been made pursuant to this Section 4.07 (i.e., the Cash
                                                                  ----          
and Fund Subaccounts or the Cash, Fund and Stock Subaccounts) shall be forfeited
by the Participant and the Participant will not be eligible to recommence
deferrals until the first of the year that follows a one (1) year period
commencing on the date of withdrawal, and then only if otherwise eligible under
the terms of the Plan.  The amount payable under this section shall be paid
within forty-five (45) days following receipt of written notice by the
Committee.

5.   SURVIVOR BENEFIT

     If a Participant dies prior to commencement of any payments under this
Plan, including payment of the supplemental retirement benefit, no supplemental
retirement benefit shall be payable, but in lieu thereof the survivor benefit
specified in the Participation Agreement shall be paid to the Participant's
designated beneficiary or, failing such designation, to the Participant's
estate.

6.   WITHDRAWAL OF DEFERRED AMOUNTS

     6.01   Other than pursuant to Section 4.04, 4.07 or termination, a
Participant may not receive any amount deferred under this Plan, unless the
Committee determines that, based upon uniform, established standards, the
Participant has suffered a severe financial hardship.  For these purposes, a
severe financial hardship shall have the same meaning as under Section 3.02(e).
Notwithstanding the foregoing, amounts deferred under the Stock Subaccount shall
not be distributable due to such a severe financial hardship if the Participant
is a reporting person subject to the provisions of Section 16(a) of the Act.
<PAGE>
 
     6.02   Upon such determination, the Participant will receive an amount
necessary to satisfy the financial hardship but in no event more than the total
of amounts deferred plus  earnings credited to the Participant's account at the
date of withdrawal.

     6.03   A Participant who has made a withdrawal will not be eligible to
recommence deferrals for a new Deferral Period under the Plan until the first of
the year that follows a one (1) year period commencing on the date of
withdrawal.

7.   AMOUNTS OF SUPPLEMENTAL RETIREMENT AND SURVIVOR BENEFITS

     The amount of the supplemental retirement and survivor benefits shall be
prescribed in accordance with a general plan applicable to all Participants
which has been established by the Committee and approved by the Management
Development and Compensation Committee of the Board of Directors.

8.   FINANCING

     The Company may finance obligations under this Plan by the purchase of one
(1) or more policies of life insurance upon the lives of Participants, with the
Company as owner of and beneficiary under such policies.  No Participant shall
have any right or interest in any such policy or the proceeds thereof or in any
other specific fund or asset of the Company as a result of the Plan.  The rights
of Participants to benefit payments hereunder shall be no greater than those of
an unsecured creditor.  Each Participant shall cooperate fully in the
application for, and in the maintenance of, any such policy or policies of
insurance upon the Participant's life.

9.   AMENDMENT OR TERMINATION

     9.01   The Board of Directors of the Company may, by written resolution,
terminate or amend this Plan at any time.  However, the  Committee may amend
this Plan, retroactively if necessary, by means of a resolution, to bring this
Plan into conformity with any law or governmental regulation relating to plans
or trusts of this character.  The rights of any Participant under a
Participation Agreement shall not be impaired by such termination or amendment
except as provided under Section 9.02.

     9.02   If the reason for termination or amendment is a change in the tax
laws adversely affecting the financing of the supplemental retirement benefit or
survivor benefit under the Plan, then the Board of Directors of the Company may
terminate all (but not less than all) of the then existing Participation
Agreements except any under which benefits are then being paid.
<PAGE>
 
            (a) Each Participant with a terminated Agreement will be paid in
     lieu of any and all other benefits hereunder an amount equal to the
     Participant's Supplemental Retirement Account balance as of the date of
     termination.

            (b) Such amount resulting from termination may be paid in a lump sum
     within forty-five (45) days of the date of such termination or in such
     other manner and at such other time or times as the Committee may
     reasonably determine.

10.  ADMINISTRATION

     10.01  Responsibility for establishing the requirements for participation
and for administration of the Plan shall be vested in the Committee, which shall
have the full and exclusive discretionary authority to interpret the Plan or the
Participation Agreements, to determine all benefits and to resolve all questions
arising from the administration, interpretation, and application of their
provisions, either by general rules or by particular decisions, including
determinations as to whether a claimant is eligible for benefits, the amount,
form and timing of benefits, and any other matter (including any question of
fact) raised by a claimant or identified by the Committee.  The Committee may
delegate administrative tasks as necessary to persons who are not Committee
members.  All decisions of the Committee shall be conclusive and binding upon
all affected persons.

     10.02  The expenses of administering the Plan shall be borne by the
Company.  No member of the Committee shall receive any remuneration for service
in such capacity.  However, expenses of the Committee or its members paid or
incurred in connection with administering the Plan shall be reimbursed by the
Company.

     10.03  The Company shall indemnify and hold harmless the members of the
Committee against any and all claims, loss, damage, expense or liability arising
from any action or failure to act with respect to this Plan, except in the case
of gross negligence or willful misconduct.

11.  CLAIMS PROCEDURE

hearing.  On review, the claimant may have representation, examine pertinent
documents, and submit issues and comments in writing.

     11.04  FINAL DECISION.  The decision on review shall normally be made
within sixty (60) days.  If an extension of time is required for a hearing or
other special circumstances, the claimant shall be notified and the time limit

review shall be final and shall bind all parties concerned.

12.  MISCELLANEOUS

     12.01  No amount payable under the Plan or any Participation Agreement

or charge by a Participant or the Beneficiary of a Participant except as may be
required by law.

     12.02  Neither the Plan nor any action taken hereunder shall be construed
as giving any employee who is a Participant or who becomes a Participant any
right to be retained in the employ of the Company.

     12.03  "Retirement" under the Company Pension Plan shall mean retirement
under the Retirement Income Plan.  However, in the event of any retirement
arising by reason of a "Change in Control" and which, as set forth in the
Retirement Income Plan, results in an enhancement of an employee Participant's
retirement income then:

            (a) "Retirement" for purposes of this Plan shall mean the
     Participant's sixty-fifth (65th) birthday; or
<PAGE>
 
            (b)  A Participant may elect to treat retirement as "retirement"
     under the Plan subject to the penalties imposed in an early retirement
     opportunity under Sections 4.04 and 4.06 of this Plan.

     12.04  The Management Development and Compensation Committee of the Board
of Directors may at any time direct the Company to establish a Trust to secure
part or all of the obligations of the Company with respect to payments and
benefits  to be paid to Participants under this Plan.  Funding of the Trust
shall be at the direction of the Board of Directors and shall be irrevocable in
nature.  Notwithstanding the foregoing, the assets of such Trust shall be
subject to the claim of the general creditors of the Company in the event of
bankruptcy or insolvency of the Company.

     2.02 Eligibility.
          ----------- 

          (a)  Except as otherwise provided in this Section 2.02 or Section 3 of
               this Plan, any Participant whose employment with the Company is
               terminated by the Company shall be eligible for benefits under
               the Appendix, Schedule 2, unless the termination is:

               (1)  because of the death or Disability of the Employee;
               (2)  by the Company for Cause (as defined in Subsection 2.03);
               (3)  by the Employee;
               (4)  by the Company in connection with the sale or transfer of a
                    plant, unit, division, or subsidiary of the Company to a
                    successor (whether by reason of a sale of stock or assets),
                    by means of which the Employee continues employment with the
                    successor organization or is offered employment with the
                    successor organization in essentially the same or a similar
                    position, with comparable compensation, within the same
                    geographical area, even if not at the same plant or office;
               (5)  by the Company and the employee was offered essentially the
                    same or a similar position, with comparable compensation,
                    within the 

                                      -2-
<PAGE>
 
                    same geographical area, even if not at the same plant,
                    office or location.

          (b)  Any Participant who is involuntarily terminated, as determined by
               the Committee, due to a reduction in the workforce of the office
               or manufacturing location at which the Participant is employed,
               will be eligible for severance benefits set forth in the
               Appendix, Schedule 3 in lieu of benefits under Schedule 2,
               provided:  (1) the Participant is notified in writing before
               January 1, 1999, that (s)he will be terminated, and his or her
               employment ends before January 1, 2000; and (2)  the Participant
               is not otherwise excluded from receiving benefits under Paragraph
               (a) above. This benefit is provided out of concern for employees
               who lose their jobs during this time of significant technological
               change and restructuring of the work force.

          (c)  Any Participant who is involuntarily terminated, as determined by
               the Committee, due to a finding of the Executive Committee of the
               Board of Directors that the requirements of the Participant's
               position or position status have been fundamentally altered,
               including changes due to a lack of promotability, will be
               eligible for severance benefits set forth in the Appendix,
               Schedule 3 in lieu of benefits under Schedule 2, provided:  (1)
               the Participant is notified in writing before January 1, 1999,
               that (s)he will be terminated, and his or her employment ends
               before January 1, 2000; and (2)  the Participant is not otherwise
               excluded from receiving benefits under Paragraph (a) above. This
               benefit is provided out of concern for employees who lose their
               jobs because the requirements of their positions or their
               position status have been fundamentally altered due to economic
               conditions, or present or anticipated structural, procedural or
               technological change.

          (d)  Any Participant who is terminated by the Company for performance-
               related reasons after January 1, 1999, will be eligible for
               severance benefits as set forth in the Appendix, Schedule 1,
               provided that the Participant is not otherwise excluded from
               receiving benefits under Paragraph (a) or Section 3 of this Plan.
               This section is not intended to otherwise make benefits available
               to employees terminated by the Company for Cause (as defined in
               Subsection 2.03).

     2.03 Termination for Cause.  Termination of a Participant's employment for
          ---------------------                                                
Cause shall be deemed to have occurred if the Participant's employment is
terminated by the Company due to the Participant's deliberately engaging in
gross misconduct which is demonstrably and materially 

                                      -3-
<PAGE>
 
injurious to the Company, monetarily or otherwise, including but not limited to
fraud or embezzlement by the Employee.

For purposes of this Section 2.03, no act, or failure to act, on the part of the
Participant shall be considered "deliberate" unless done, or omitted to be done,
by the Participant not in good faith and without reasonable belief that such
action or omission was in the best interests of the Company.

     2.04 Effect of Participant's Eligibility to Retire.  No eligible
          ---------------------------------------------              
Participant will be denied severance benefits solely because such Participant is
also eligible for retirement benefits under another plan of the Company.

     2.05 Reservation of Rights.  The Company reserves the right for the
          ---------------------                                         
Committee to depart from the Schedules listed in the Appendix where the eligible
Participant's attendance, job performance, or other job-related conduct appears
to the Company to justify an upward or downward adjustment in benefits.
However, in no event shall the maximum benefit payable under the Plan exceed
twice such Participant's annual compensation, as defined in 29 C.F.R. Section
2510.3-2(b)(2); nor shall the maximum payment period exceed 24 months after the
termination of the Participant's employment.

     2.06 Classification of Employees to Whom the Plan Does Not Relate.  The
          ------------------------------------------------------------      
severance policies and procedures contained in this Plan do not apply to
employees classified by the Company as temporary or hourly paid employees.

3.   BENEFITS

          for services performed prior to the Date of Termination shall be paid

          ------------

          -------------                                                  
          notified in writing prior to that date, whose severance pay shall be
          calculated in the manner in effect prior to that date, the Participant
          shall be paid a severance payment related to the Participant's Years
          of Service and Earnings.  The amount of severance payment shall be
          calculated using the relevant Schedule of the Appendix as 

                                      -4-
<PAGE>
 
          determined under Sections 2.02 and 2.05. Weeks of Severance for
          partial years of service will be calculated proportionately. A week's
          pay shall be the Earnings divided by 52.

     (d)  Mode of Payment.  After the eligible Participant has satisfied all
          ---------------                                                   
          conditions precedent to receive severance benefits, such benefits will
          be paid to the Participant by salary continuation until the severance
          allowance is exhausted, unless the Plan Administrator approves a lump
          sum payment or some combination of periodic or lump sum payments.

     (e)  Insurance Benefits.  An eligible Participant's insurance benefits
          ------------------                                               
          shall be determined in accordance with the applicable insurance
          benefit plan.

     3.02 Other Circumstances That Can Result in Disqualification, Forfeiture,

          Reduction or Suspension of Severance Benefits.
          --------------------------------------------- 

     (a)  Elective Deductions.  An eligible Participant may elect to have
          -------------------                                            
          insurance premiums for Company-sponsored insurance plans deducted from
          severance payments.

     (b)  Legally Required Deductions.  Appropriate federal, state and local
          ---------------------------                                       
          taxes will be withheld from all severance payments.

     (c)  Effect of Rehire or Reinstatement (Or An Offer of Same).  If an
          --------------------------------------------------------       
          eligible Participant is granted severance benefits and the Participant
          is either rehired or reinstated as a regular salaried employee on a
          regular full-time basis by the Company (or is offered rehire or
          reinstatement on a full-time basis by the Company) before the end of
          the pay continuation period, then the Participant forfeits any unpaid
          severance payments for the periods following rehire or reinstatement
          (or the date of offer of same).

     (d)  Effect of Sale of Portion of Business Assets.  Any Participant whose
          --------------------------------------------                        
          employment with the Company is terminated during or in anticipation of
          a sale of some, but not all, assets of the Company is not entitled to
          severance benefits if the purchaser of such assets offers to employ
          the Participant for substantially the same or greater compensation as
          the Participant was receiving immediately prior to the Date of
          Termination, and such offer of employment is made by the purchaser
          within no later than eight (8) weeks after the termination of the
          Participant's employment by the Company.

     (e)  Effect of Participant Misconduct.  Any Participant who accepts

          severance benefits is obligated to reimburse the Company for the full
          amount of such payments if the Participant subsequently discloses any
          of the Company's trade secrets, violates any 

                                      -5-
<PAGE>
 
          written covenants between the Participant and the Company, or
          otherwise engages in conduct that may adversely affect the Company's
          reputation or business relations. Likewise, a Participant who engages
          in such conduct shall forfeit any right to any unpaid severance
          payments.

     (f)  Effect of Adverse Economic Conditions.  The Company may permanently
          -------------------------------------                              
          suspend benefits under severance allowances in pay status (1) in the
          event of the Company's insolvency, liquidation, or bankruptcy
          reorganization or (2) in the event the cost of providing such benefits
          would lead to the Company's insolvency, liquidation, or bankruptcy
          reorganization.

     (g)  Effect of Other Severance Pay Laws.  Any severance benefits provided
          ----------------------------------                                  
          by the Company under this Plan shall be reduced dollar-for-dollar by

          eligible Participant under any federal or state law.

     (h)  Effect of Catastrophes and Other Extraordinary Events.  Severance
          -----------------------------------------------------            
          payments will not be made if the Participant's employment is
          terminated because of fire, flood, explosion, bombing, earthquake or
          other disaster causing damage to the location facilities or when
          strikes, work stoppages or civil disturbances prevent continued
          operations.

     (i)  Effect of Temporary Layoffs.  Severance payments will not be made if a
          ---------------------------                                           
          layoff is deemed to be temporary and of limited duration, e.g., a need
          for inventory reduction in a production facility or activities closely
          aligned with it.  During such periods, Participants are encouraged to
          take any available vacation to which they may be entitled.

     (j)  Non-Compete Agreement.  The Participant who has been involuntarily
          ---------------------                                             
          terminated may be required to execute a Non-Compete Agreement when the
          Committee determines that such an Agreement is required to protect the
          Company.  Any Participant who is asked to execute a Noncompete
          Agreement will receive severance in the amount of One Thousand Dollars
          ($1,000) as consideration for the Noncompete Agreement.  The Non-
          Compete Agreement must be signed and returned to the Company within 60
          days after the Participant's termination date in order for the
          Participant to receive benefits under this Plan.

     3.03 Condition Precedent to Severance Payments.  For the Employee who
          -----------------------------------------                       
becomes eligible for severance payments under Section 2.02 of the Plan because
the Company eliminates the Participant's position or because the Participant's
position has been fundamentally altered, severance payments will not be paid
under any circumstances until the eligible Participant 

                                      -6-
<PAGE>
 
executes a Company approved release of the Participant's then existing rights
and claims against the Company. The release must be signed and returned to the
Company within 60 days after the Participant's Date of Termination in order for
the Participant to receive benefits under this Plan. For the Employee who
becomes eligible for benefits under the Plan for any other reason, the Committee
may but is not required to obtain the release mentioned above.

     3.04 Impact of Armstrong Employment Protection Plan.  Notwithstanding
          ----------------------------------------------                  
anything to the contrary in this Plan, in the event the Participant's Date of
Termination coincides with or follows a change in control, as defined in the
Armstrong Employment Protection Plan, no benefits will be paid under this Plan.
This Plan applies only in the case of an eligible Participant whose employment
has been terminated by the Company prior to the change in control and who is
otherwise eligible to receive a benefit hereunder.

4.   AMENDMENT OR TERMINATION.

     The Executive Committee of the Board of Directors of the Company may by
written resolution terminate or amend this Plan at any time, provided that no
amendment or termination of the Plan may adversely affect the amount, type, or
timing of payment of benefits accrued and due and payable hereunder with respect
to Participants whose employment has been terminated, except as provided in
Section 3.02 of this Plan.  Notwithstanding the foregoing, the Executive
Committee of the Board of Directors has delegated the authority to amend the
Plan to the Retirement Committee; provided, however, that the Executive
Committee reserves the right to rescind or modify such delegation at any time
and for any reason and retains the right to amend the Plan itself at any time.

administration, interpretation and application of the Plan, either by general
rules or by particular decisions, including (but not limited to) questions
regarding eligibility for benefits hereunder and the amount, form and timing of
payments thereof, and any other matter (including any question of fact) raised
by a claimant or identified by the Committee.  Any such determination by the
Committee shall be binding and conclusive upon all persons.  The Committee may
correct any defect, supply any information, or reconcile any inconsistency in
such manner and to such extent as shall be deemed necessary or advisable by it
to carry out the purpose of this Plan.  The Committee may delegate
administrative tasks as necessary to persons who are not Committee members.

     5.02 All expenses of administering the Plan shall be borne by the Company.
No member of the Committee shall receive any remuneration for service in such
capacity.  However,

<PAGE>
 
expenses of the Committee or its members paid or incurred in connection with
administering the Plan shall be reimbursed by the Company.

     5.03 The Company may purchase insurance to cover potential liability of the
Plan's fiduciaries.  The Plan may purchase insurance for its fiduciaries and/or
for itself to cover liability and losses occurring by reason of the act or
omission of a fiduciary.

     5.04 The Plan is unfunded and all severance payments under the Plan shall
be made from the general assets of the Company.

6.   SUCCESSORS; BINDING AGREEMENT

     6.01 In the event of a sale or transfer of a plant, unit, division, or
subsidiary of the Company to a successor (whether by reason of a sale of stock
or assets) by means of which any Employee continues employment with the
successor organization or is offered employment with the successor organization,
the Company shall not be obliged to negotiate with the successor organization
over whether to establish any severance pay plan, policy, or practice with
respect to such Employees or whether to cover such Employees under any existing
severance pay plan, policy, or practice already maintained by the successor
organization.

     6.02 All rights of an eligible Employee hereunder shall inure to the
benefit of and be enforceable by such Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.  If an eligible Employee should die after having
satisfied all conditions precedent to the receipt of such benefits, but prior to
receiving all amounts of benefits payable hereunder, all such amounts, unless
otherwise provided herein, shall be paid in a lump sum in accordance with the
terms of this Plan to the Employee's devisee, legatee, or other designee or, if
there be no such designee, to the Employee's estate.

7.   ARBITRATION.

     Any dispute or controversy arising under or in connection with this Plan
shall be settled exclusively by arbitration in Lancaster County, Pennsylvania,
in accordance with the rules of the American Arbitration Association then in
effect.  Judgment may be entered on the arbitrator's award in any court having
jurisdiction.

8.   MISCELLANEOUS

     8.01 No amount payable under the Plan shall be subject to assignment,
transfer, sale, pledge, encumbrance, alienation or change by an eligible
Employee or the beneficiary of such Employee except as may be required by law.

                                      -8-
<PAGE>
 
     8.02 Neither the Plan nor any action taken hereunder shall be construed
either (1) as giving any individual employed by the Company any right to receive
severance benefits of a type or in any amount similar to the benefits described
in Section 3.01 above, unless the individual qualifies for benefits under this
Plan; or (2) as giving any Employee any right to be retained in the employ of
the Company.

     8.03 Payments of benefits under this Plan shall be made in lieu of payments
of any severance benefits of a type similar to the benefits described in Section
3.01 above that may be offered under any written or unwritten severance pay
policy maintained by the Company and there shall be no duplication of benefits
previously paid under any such policy.

     8.04 This Plan shall be governed by and construed in accordance with the
laws of the Commonwealth of Pennsylvania except to the extent preempted by the
Employee Retirement Income Security Act or any other federal law.

     8.05 The invalidity or unenforceability of any provision of this Plan shall
not affect the validity or enforceability of any other provision of this Plan,
which shall remain in full force and effect.

     8.06 Any notice or other communication provided for in this Plan shall be
in writing and, unless otherwise expressly stated herein, shall be deemed to
have been duly given if mailed by United States registered mail, return receipt
requested, postage prepaid addressed in the case of an Employee to the
Employee's office at the Company with a copy to the Employee's residence and in
the case of the Company to its principal executive offices, attention of the

adopt administrative rules, regulations, and guidelines for the Plan, and to
impose such terms, conditions, and restrictions on grants as it deems
appropriate. The Committee, in its discretion, may allow certain optionees
holding unexercised Incentive Stock Options to convert such options to

    Stock issued under the Plan may be treasury shares or authorized but
    unissued shares. No fractional shares shall be issued under the Plan.
<PAGE>
 
(b) If any Stock Option granted under the Plan expires or terminates, the
    underlying shares of Common Stock may again be made available for the
    purposes of the Plan. Any shares of Common Stock that have been granted as
    Restricted Stock Awards, or that have been reserved for distribution in
    payment for Performance Restricted Shares but are later forfeited or for any
    other reason are not payable under the Plan, may again be made available for
    the purposes of the Plan.

    to any Participant in the form of Stock Options, Stock Appreciation Rights,
    Performance Restricted Shares and Restricted Stock Awards in any one
    calendar year is 300,000.

1.6 ELIGIBILITY AND PARTICIPATION

  Participation in the Plan shall be limited to officers, who may also be

                          ARTICLE II - STOCK OPTIONS

2.1 GRANT OF STOCK OPTIONS

  The Committee may from time to time, subject to the provisions of the Plan,
grant Stock Options to such Participants. The Committee shall determine the
number of shares of Common Stock to be covered by each Stock Option and shall
have the authority to grant Incentive Stock Options, Nonstatutory Stock Options,
or a combination thereof. Furthermore, the Committee may grant a Stock
Appreciation Right in connection with a Stock Option, as provided in Article
III.

2.2 INCENTIVE STOCK OPTION EXERCISE LIMITATIONS

  The aggregate Fair Market Value (determined at the time an Incentive Stock
Option is granted) of the shares of Common Stock with respect to which an
Incentive Stock Option is exercisable for the first time by a Participant during
any calendar year (under all plans of the Company) shall not exceed $100,000 or
such other limit as may be established from time to time under the Code.

2.3 OPTION DOCUMENTATION

  Each Stock Option shall be evidenced by a written stock option agreement
between the Company and the Participant to whom such option is granted,
specifying the number of shares of Common Stock that may be acquired by its
exercise and containing such terms and conditions consistent with the Plan as
the Committee shall determine.

2.4 EXERCISE PRICE

  The price at which each share covered by a Stock Option may be acquired shall
be determined by the Committee at the time the option is granted and shall not
be less than the Fair Market Value of the underlying shares of Common Stock on
the day the Stock Option is granted. The exercise price will be subject to
adjustment in accordance with the provisions of Section 7.1 of the Plan.

2.5 EXERCISE OF STOCK OPTIONS

(a) Exercisability. Stock Options shall become exercisable at such times and
    upon the satisfaction of such conditions and in such installments as the
    Committee may provide at the time of grant.

(b) Option Period. For each Stock Option granted, the Committee shall specify
    the period during which the Stock Option may be exercised, provided that no
    Stock Option shall be exercisable after the expiration of ten years from the
    date the option was granted.

(c) Exercise in the Event of Termination of Employment.

    (i) Death: Unless otherwise provided by the Committee at the time of grant,
        -----  
        in the event of death of the Participant, the option must be exercised
        by the Participant's estate or beneficiaries prior to its expiration.
        Each option may be exercised as to all or any portion thereof regardless
        of whether or not fully exercisable under the terms of the grant.
<PAGE>
 
    (ii)  Disability: Unless otherwise provided by the Committee at the time of
          ----------
          grant, in the event of the Disability of the Participant, the option
          must be exercised prior to its expiration. An unexercised Incentive
          Stock Option will cease to be treated as such and will become a
          Nonstatutory Stock Option twelve months following the date of
          termination due to Disability. Each option may be exercised as to all
          or any portion thereof regardless of whether or not fully exercisable
          under the terms of the grant.

    (iii) Retirement: Unless otherwise provided by the Committee at the time of
          ----------          
          grant, in the event of the Retirement of the Participant the option
          must be exercised prior to its expiration. An unexercised Incentive
          Stock Option will cease to be treated as such and will become a
          Nonstatutory Stock Option three months following the date of
          Retirement.

    (iv)  Other Terminations: Unless otherwise provided by the Committee at the
          ------------------
          time of grant, in the event a Participant ceases to be an employee of
          the Company for any reason other than death, Disability, or
          Retirement, options which are exercisable on the date of termination
          must be exercised within three months after termination. All options
          which are not exercisable on the date of termination shall be
          cancelled.

    (v)   Extension of Exercise Period: Notwithstanding all other provisions
          ----------------------------     
          under Section 2.5(c), in the event a Participant's employment is
          terminated, the Committee may, in its sole discretion, extend the post
          termination period during which the option may be exercised, provided
          however that such period may not extend beyond the original option
          period.

(d) Exercise in the Event of Change in Control. In the event of any Change in
    Control, all Stock Options shall immediately become exercisable without
    regard to the exercise period set forth in 2.5(a).

2.6 METHOD OF EXERCISE

  The option may be exercised in whole or in part from time to time by written
request received by the Treasurer of the Company. The option price of each share
acquired pursuant to an option shall be paid in full at the time of each
exercise of the option either (1) in cash, or (2) by delivering to the Company
shares of Common Stock or any combination of shares and cash having an aggregate
Fair Market Value equal to the option price of the shares being acquired.
However, shares of Common Stock previously acquired by the Participant under the
Plan or any other incentive plan of the Company shall not be utilized for
purposes of payment upon the exercise of an option unless those shares have been
owned by the Participant for a twelve-month period or such longer period as the
Committee may determine.

                    ARTICLE III - STOCK APPRECIATION RIGHTS

3.1 GRANT OF STOCK APPRECIATION RIGHTS

  The Committee may, in its discretion, grant Stock Appreciation Rights in
connection with all or any part of an option granted under the Plan. Any Stock
Appreciation Right granted in connection with an option shall be governed by the
terms of the Stock Option agreement and the Plan.

3.2 EXERCISE OF STOCK APPRECIATION RIGHTS

  Stock Appreciation Rights shall become exercisable under the Stock Option
terms set forth in Section 2.5 but shall be exercisable only when the Fair
Market Value of the shares subject thereto exceeds the option price of the
related option.

3.3 METHOD OF EXERCISE

(a) Stock Appreciation Rights shall permit the Participant, upon exercise of
    such rights, to surrender the related option, or any portion thereof, and to
    receive, without payment to the Company (except for applicable withholding
    taxes), an amount equal to the excess of the Fair Market Value over the
    option price. Such amount shall be paid in shares of Common Stock valued at
    Fair Market Value on the date of exercise.

(b) Upon the exercise of a Stock Appreciation Right and surrender of the related
    option, or portion thereof, such option, to the extent surrendered, shall be
    terminated, and the shares covered by the option so surrendered shall no
    longer be available for purposes of the Plan.

                  ARTICLE IV - PERFORMANCE RESTRICTED SHARES

4.1 GRANT OF PERFORMANCE RESTRICTED SHARES

  The Committee may from time to time grant Performance Restricted Shares to
Participants under which payment may be made in shares of Common Stock if the
performance of the Company meets certain goals established by the Committee.
Such Performance Restricted Shares shall be subject to the provisions of the
Plan terms and conditions, and, if earned, a Vesting Period and a Restriction
Period as the Committee shall determine.

4.2 PERFORMANCE RESTRICTED SHARE AGREEMENT

  Each grant of Performance Restricted Shares shall be evidenced by a written
agreement between the Company and Participant to whom such shares are granted.
The agreement shall specify the number of Performance Restricted Shares granted,
the terms and conditions of the grant, the duration of the Performance Period,
the performance goals to be achieved, and the Vesting Period and the Restriction
Period applicable to shares of Common Stock earned.

4.3 COMMON STOCK EQUIVALENT

  Each Performance Restricted Share shall be credited to an account to be
maintained for each such Participant during the Performance Period and shall be
deemed to be the equivalent of one share of Common Stock. At the conclusion of
the Performance Period, Performance Restricted Shares earned, if any, shall be
converted to shares of Common Stock subject to a Vesting Period and a
Restriction Period.

4.4 PERFORMANCE GOALS

  Performance Restricted Share awards shall be conditioned upon the Company's
attainment of a specified goal with respect to one or more of the following
performance measures: (i) total shareholder return; (ii) EVA as defined below;
(iii) return on shareholders' equity; (iv) return on capital; (v) earnings per
share; (vi) sales; (vii) earnings; (viii) cash flow; and (ix) operating income.
EVA equals the dollar amount arrived at by taking net operating profit after
taxes and subtracting a charge for the use of the capital needed to generate
that profit. The Committee shall determine a minimum performance level below
which no Performance Restricted Shares shall be payable and a performance
schedule under which the number of shares earned may be less than, equal to, or
greater than the number of Performance Restricted Shares granted based upon the
Company's performance. The Committee may adjust the performance goals and
measurements to reflect significant unforeseen events; provided, however, that
the Committee may not make any such adjustment with respect to any award of
Performance Restricted Shares to an individual who is then a "covered employee"
as such term is defined in Regulation 1.162-27(c)(2) promulgated under Section
162(m) of the Code ("Section 162(m)"), if such adjustment would cause
compensation pursuant to such Performance Restricted Share award to cease to be
performance-based compensation under Section 162(m).

4.5 PERFORMANCE PERIOD

  The Committee shall establish a Performance Period applicable to each grant of
Performance Restricted Shares. Each such Performance Period shall commence on
January 1 of the calendar year in which grants are made. There shall be no
limitation on the number of Performance Periods established by the Committee,
and more than one Performance Period may encompass the same calendar year. The
Committee may shorten any Performance Period if it determines that unusual or
unforeseen events so warrant.

4.6 DIVIDEND EQUIVALENTS DURING PERFORMANCE PERIOD

  During the Performance Period, a Participant shall be entitled to receive
Dividend Equivalents which shall be deemed to have been reinvested in additional
Performance Restricted Shares at the same time as such underlying Common Stock
cash dividend is paid. Performance Restricted Shares granted through such
reinvestment shall be credited to the Participant's account and shall be payable
to the Participant in the same manner and at the same time as the Performance
Restricted Shares with respect to which such Dividend Equivalents were issued.
<PAGE>
 
4.7 RIGHT TO PAYMENT OF PERFORMANCE RESTRICTED SHARES

(a) At the conclusion of the Performance Period, the Committee shall determine
    the number of Performance Restricted Shares, if any, which have been earned
    on the basis of Company performance in relation to the established
    performance goals. In no event shall such number exceed 300% of the shares
    contingently granted.

(b) Performance Restricted Shares earned shall be converted to shares of Common
    Stock and shall be represented by a stock certificate registered in the name
    of the Participant. Certificates evidencing such shares shall be held in
    custody by the Company until the restrictions thereon are no longer in
    effect. After the lapse or waiver of the restrictions imposed, the Company
    shall deliver in the Participant's name one or more stock certificates, free
    of restrictions, evidencing the shares of Common Stock to which the
    restrictions have lapsed or been waived.

4.8 VESTING PERIOD

  At the time a Performance Restricted Share grant is made, the Committee shall
establish a period of time (the "Vesting Period") applicable to such shares
earned, if any, which shall begin at the end of the Performance Period. During
the Vesting Period, Performance Restricted Shares shall be subject to the risk
of forfeiture. The Committee may provide for the lapse of such restrictions in
installments and may accelerate or waive such restrictions, in whole or in part,
based on service and such other factors as the Committee may determine.

4.9 RESTRICTION PERIOD

  At the time a Performance Restricted Share grant is made, the Committee shall
establish a period of time (the "Restriction Period") applicable to such shares
earned, if any, which shall begin at the end of the Performance Period. During
the Restriction Period, the Participant shall not be permitted to sell, assign,
transfer, pledge or otherwise dispose of Performance Restricted Shares that have
been earned. The Committee may provide for the lapse of such restrictions in
installments, in whole or in part, based on service and such other factors as
the Committee may determine.

4.10 OTHER TERMS AND CONDITIONS

  Performance Restricted Shares earned and restricted shares received with
respect to such shares shall be subject to the following terms and conditions:

(a) Except as otherwise provided in the Plan or in the Performance Restricted
    Share agreement, the Participant shall have all the rights of a shareholder
    of the Company, including the right to vote the shares.

(b) Cash dividends paid with respect to Performance Restricted Shares shall be
    reinvested to purchase additional shares of Common Stock that shall be
    subject to the same terms, conditions, and restrictions that apply to the
    Performance Restricted Shares with respect to which such dividends were
    issued.

(c) Except as otherwise provided in the Plan or in the Performance Restricted
    Share agreement, upon termination of a Participant's employment, all
    unvested shares subject to restriction shall be forfeited by the
    Participant.

4.11 TERMINATION OF EMPLOYMENT - PROVISIONS DURING A PERFORMANCE PERIOD

(a) In the event a Participant terminates employment during a Performance Period
    by reason of death, Disability, or Retirement, the Participant shall be
    entitled to the full number of shares earned, if any, as long as the
    Participant had completed a minimum of one year of employment during the
    Performance Period. If the termination of employment is by reason of death
    or Disability, all other restrictions shall lapse and shares of Common Stock
    shall be issued to the Participant or the Participant's designated
    beneficiary following the Performance Period. If the termination of
    employment is by reason of Retirement, any applicable Restriction Period
    shall continue in effect, but in no event beyond the end of the three-year
    period following the Participant's Retirement. Following the expiration of
    such Restriction Period, shares of Common Stock shall be issued to the
    Participant. In the event the Participant had not completed one year of
    employment during the Performance Period, the Participant shall forfeit all
    rights to earn such Performance Restricted Shares.

(b) If a Participant terminates employment for any reason other than death,
    Disability, or Retirement, the Participant shall forfeit all rights to earn
    such Performance Restricted Shares.
<PAGE>
 
(c) Notwithstanding Sections 4.11(a) and 4.11(b), in the event a Participant's
    employment is terminated under special circumstances, the Committee may, in
    its sole discretion, continue a Participant's rights to earn any or all
    Performance Restricted Shares and waive in whole or in part any or all
    remaining restrictions.

4.12 TERMINATION OF EMPLOYMENT - PROVISIONS FOLLOWING A PERFORMANCE PERIOD

(a) In the event a Participant terminates employment following a Performance
    Period by reason of death, Disability, or Retirement, all Performance
    Restricted Shares earned shall immediately vest. If the termination of
    employment is by reason of death or Disability, all other restrictions shall
    lapse and shares of Common Stock shall be issued to the Participant or the
    Participant's designated beneficiary. If the termination of employment is by
    reason of Retirement, any applicable Restriction Period shall continue in
    effect, but in no event beyond the end of the three-year period following
    the Participant's Retirement. Following the expiration of such Restriction
    Period, shares of Common Stock shall be issued to the Participant.

(b) If a Participant terminates employment for any reason other than death,
    Disability, or Retirement, the Participant shall forfeit all Performance
    Restricted Shares subject to the Vesting Period. Any applicable Restriction
    Period shall continue in effect, but in no event beyond the end of the
    three-year period following the Participant's date of termination of
    employment. Following the expiration of such Restriction Period, shares of
    Common Stock shall be issued to the Participant.

(c) Notwithstanding Sections 4.12 (a) and 4.12 (b), in the event a Participant's
    employment is terminated under special circumstances, the Committee may, in
    its sole discretion, waive in whole or in part any or all remaining
    restrictions.

4.13 CHANGE IN CONTROL PROVISIONS

  In the event of any Change in Control, all Performance Restricted Shares
earned shall immediately vest and restrictions shall lapse on all shares subject
to restrictions as of the date of such Change in Control. Further, all
Performance Restricted Shares granted, including those granted pursuant to
Dividend Equivalents, shall be deemed to have been earned to the maximum extent
permitted pursuant to Section 4.4 for any Performance Period not yet completed
as of the effective date of such Change in Control.

                      ARTICLE V - RESTRICTED STOCK AWARDS

5.1 AWARD OF RESTRICTED STOCK

  The Committee may authorize awards of Common Stock to officers and key
employees subject to terms, conditions, and a Restriction Period as the
Committee shall determine. Restricted Stock Awards shall be used for the
purposes of recruitment, recognition, and retention of key employees vital to
the Company's success.

5.2 RESTRICTED STOCK AWARD AGREEMENT

  Each Restricted Stock Award shall be evidenced by a written agreement between
the Company and the Participant to whom such award is granted. The agreement
shall specify the number of shares awarded, the terms and conditions of the
award, the Restriction Period, the rights of the Participant, and the
consequences of forfeiture consistent with the Plan as the Committee shall
determine.

5.3 AWARDS AND CERTIFICATES

  Shares of Common Stock awarded pursuant to a Restricted Stock Award shall be
registered in the name of the Participant. Certificates evidencing such shares
shall be held in custody by the Company until the restrictions thereon are no
longer in effect. After the lapse or waiver of the restrictions imposed, the
Company shall deliver in the Participant's name one or more stock certificates,
free of restrictions, evidencing the shares of Common Stock to which the
restrictions have lapsed or been waived.
<PAGE>
 
5.4 RESTRICTION PERIOD

  At the time a Restricted Stock Award is made, the Committee shall establish a
period of time (the "Restriction Period") applicable to such award during which
the shares of restricted stock are subject to the risk of forfeiture and the
Participant shall not be permitted to sell, assign, transfer, pledge, or
otherwise dispose of such shares. The Committee may provide for the lapse of
such restrictions in installments and may accelerate or waive such restrictions,
in whole or in part, based on service and such other factors as the Committee
may determine.

5.5 OTHER TERMS AND CONDITIONS

  Shares of restricted stock awarded and restricted shares received with respect
to such shares shall be subject to the following terms and conditions:

(a) Except as otherwise provided in the Plan or in the Restricted Stock Award
    agreement, the Participant shall have all the rights of a shareholder of the
    Company, including the right to vote the shares.

(b) Cash dividends paid with respect to restricted shares shall be reinvested to
    purchase additional shares of Common Stock that shall be subject to the same
    terms, conditions, and restrictions that apply to the Restricted Stock Award
    with respect to which such dividends were issued.

(c) Except as otherwise provided in the Plan or in the Restricted Stock Award
    agreement, upon termination of a Participant's employment, all shares
    subject to restriction shall be forfeited by the Participant.

5.6 TERMINATION OF EMPLOYMENT

(a) In the event a Participant terminates employment during the Restriction
    Period by reason of death or Disability, restrictions shall lapse on all
    shares subject to restriction at the time of such termination.

(b) In the event a Participant terminates employment during the Restriction
    Period by reason of Retirement, restrictions shall lapse on a proportion of
    any shares subject to restriction at the time of such Retirement. Any
    applicable Restriction Period shall continue in effect, but in no event
    beyond the end of the three-year period following the Participant's
    Retirement. The number of shares upon which the restrictions shall lapse
    shall be prorated for the number of months of employment during the
    Restriction Period prior to the Participant's termination of employment.

(c) If a Participant terminates employment for any reason other than death,
    Disability, or Retirement, the Participant shall forfeit all shares subject
    to restriction.

(d) Notwithstanding Sections 5.6 (a), 5.6 (b) and 5.6 (c), in the event a
    Participant's employment is terminated under special circumstances, the
    Committee may, in its sole discretion, waive in whole or in part any or all
    remaining restrictions.

5.7 CHANGE IN CONTROL PROVISIONS

  In the event of any Change in Control, restrictions shall lapse on all shares
subject to restrictions as of the date of such Change in Control.

          ARTICLE VI - SHARE TAX WITHHOLDING AND DEFERRAL OF PAYMENT

6.1 SHARE TAX WITHHOLDING

(a) At the discretion of the Committee, share tax withholding may be included as
    a term of any grant of Stock Options, Stock Appreciation Rights, Performance
    Restricted Shares, and Restricted Stock Award.

(b) Share tax withholding shall entitle the Participant to elect to satisfy, in
    whole or in part, any tax withholding obligations in connection with the
    issuance of shares of Common Stock earned under the Plan by requesting that
    the Company either:

    (i)  withhold shares of Common Stock otherwise issuable to the Participant,
         or

    (ii) by accepting delivery of shares of Common Stock previously owned by
         the Participant.
<PAGE>
 
In either case, the Fair Market Value of such shares of Common Stock will
generally be determined on the date of exercise for Stock Options and Stock
Appreciation Rights and on the date following the Restriction Period for
Performance Restricted Shares and Restricted Stock Awards. Notwithstanding the
foregoing, in the case of a Participant subject to the reporting requirements of
Section 16(a) of the Exchange Act, no such election shall be effective unless
made in compliance with any applicable requirements of Rule 16b-3(e) or any
successor Rule under the Exchange Act.

(c) Shares of Common Stock previously acquired by the Participant under the Plan
    or any other incentive plan of the Company shall not be utilized for
    satisfaction of any withholding obligation unless those shares have been
    owned by the Participant for a twelve-month period or such longer period as
    the Committee may determine.

(d) Notwithstanding any other provision hereof to the contrary, the Committee,
    in its sole discretion may at any time suspend, terminate, or disallow any
    or all entitlements to share tax withholding previously granted or extended
    to any Participant.

6.2 DEFERRAL OF PAYMENT

  At the discretion of the Committee, a Participant may be offered the right to
defer the receipt of all or any portion of Performance Restricted Shares or
Restricted Stock Awards otherwise distributable to such Participant. Such right
shall be exercised by execution of a written agreement by the Participant (1),
with respect to Restricted Stock Awards, prior to the expiration of the
applicable Restriction Period and (2), with respect to Performance Restricted
Shares, prior to the expiration of the applicable Vesting Period. Upon any such
deferral, the number of shares of Common Stock subject to the deferral shall
remain in the custody of the Company. Cash dividends paid with respect to these
shares shall be reinvested to purchase additional shares of Common Stock that
shall be subject to the same deferral provisions. All other terms and conditions
of deferred payments shall be as contained in said written agreement.

                        ARTICLE VII - OTHER PROVISIONS

7.1 ADJUSTMENT IN NUMBER OF SHARES AND OPTION PRICES

  Grants of Stock Options, Stock Appreciation Rights, Performance Restricted
Shares, and Restricted Stock Awards shall be subject to adjustment by the
Committee as to the number and price of shares of Common Stock or other
considerations subject to such grants in the event of changes in the outstanding
shares by reason of stock dividends, stock splits, recapitalizations,
reorganizations, mergers, consolidations, combinations, exchanges, or other
relevant changes in capitalization occurring after the date of grant. In the
event of any such change in the outstanding shares, the aggregate number of
shares available under the Plan may be appropriately adjusted by the Committee.

7.2 NO RIGHT TO EMPLOYMENT

  Nothing contained in the Plan, nor in any grant pursuant to the Plan, shall
confer upon any Participant any right with respect to continuance of employment
by the Company or its subsidiaries, nor interfere in any way with the right of
the Company or its subsidiaries to terminate the employment or change the
compensation of any employee at any time.
<PAGE>
 
7.3 NONTRANSFERABILITY

  A Participant's rights under the Plan, including the right to any shares or
amounts payable, may not be assigned, pledged, or otherwise transferred except,
in the event of a Participant's death, to the Participant's designated
beneficiary or, in the absence of such a designation, by will or by the laws of
descent and distribution; provided, however, that the Committee may, in its
discretion, at the time of grant of a Nonstatutory Stock Option or by amendment
of an option agreement for an Incentive Stock Option or a Nonstatutory Stock
Option, provide that Stock Options granted to or held by a Participant may be
transferred, in whole or in part, to one or more transferees and exercised by
any such transferee, provided further that (i) any such transfer must be without
consideration, (ii) each transferee must be a member of such Participant's
"immediate family" or a trust established for the exclusive benefit of one or
more members of the Participant's immediate family; and (iii) such transfer is
specifically approved by the Committee following the receipt of a written
request for approval of the transfer (no approval shall be required for
Non-Employee Director transfers); and provided further that any Incentive Stock
Option which is amended to permit transfers during the lifetime of the
Participant shall, upon the effectiveness of such amendment, be treated
thereafter as a Nonstatutory Stock Option. In the event a Stock Option is
transferred as contemplated in this Section, such transfer shall become
effective when approved by the Committee and such Stock Option may not be
subsequently transferred by the transferee other than by will or the laws of
descent and distribution. Any transferred Stock Option shall continue to be
governed by and subject to the terms and conditions of this Plan and the
relevant option agreement, and the transferee shall be entitled to the same
rights as the Participant as if no transfer had taken place. As used in this
Section, "immediate family" shall mean, with respect to any person, any spouse,
child, stepchild or grandchild, and shall include relationships arising from
legal adoption.

7.4 COMPLIANCE WITH GOVERNMENT REGULATIONS

(a) The Company shall not be required to issue or deliver shares or make payment
    upon any right granted under the Plan prior to complying with the
    requirements of any governmental authority in connection with the
    authorization, issuance, or sale of such shares.

(b) The Plan shall be construed and its provisions enforced and administered in
    accordance with the laws of the Commonwealth of Pennsylvania applicable to 
    contracts entered into and performed entirely in such State.

7.5 RIGHTS AS A SHAREHOLDER

  The recipient of any grant under the Plan shall have no rights as a
shareholder with respect thereto unless and until certificates for shares of
Common Stock are issued to such recipient.

7.6 UNFUNDED PLAN

  Unless otherwise determined by the Committee, the Plan shall be unfunded and
shall not create (or be construed to create) a trust or separate funds. With
respect to any payment not yet made to a Participant, nothing contained herein
shall give any Participant any rights that are greater than those of a general
creditor of the Company.

7.7 FOREIGN JURISDICTION

  The Committee shall have the authority to adopt, amend, or terminate such
arrangements, not inconsistent with the intent of the Plan, as it may deem
necessary or desirable to make available tax or other benefits of the laws of
foreign countries in order to promote achievement of the purposes of the Plan.

7.8 OTHER COMPENSATION PLANS

  Nothing contained in this Plan shall prevent the Company from adopting other
or additional compensation arrangements, subject to shareholder approval if such
approval is required.
<PAGE>
 
7.9 TERMINATION OF EMPLOYMENT - CERTAIN FORFEITURES

  Notwithstanding any other provision of the Plan (other than provisions
regarding Change in Control, including without limitation Sections 2.5, 4.13 and
5.7 which shall apply in all events) and except for Performance Restricted
Shares or Restricted Stock Awards which would otherwise be free of restrictions
and the receipt of which has been deferred pursuant to Section 6.2, a
Participant shall have no right to exercise any Stock Option or Stock
Appreciation Right or receive payment of any Performance Restricted Share or
Restricted Stock Award if: (1) the Participant is discharged for willful,
deliberate, or gross misconduct as determined by the Committee in its sole
discretion or (2) if following the Participant's termination of employment with
the Company, and within a period of three years thereafter, the Participant
engages in any business or enters into any employment which the Committee in its
sole discretion determines to be (a) directly or indirectly competitive with the
business of the Company or (b) substantially injurious to the Company's
financial interest. A Participant may request the Committee in writing to
determine whether any proposed business or employment activity would justify
such a forfeiture. Such a request shall fully describe the proposed activity and
the Committee's determination shall be limited to the specific activity so
described.

                   ARTICLE VIII - AMENDMENT AND TERMINATION

8.1 AMENDMENT AND TERMINATION

  The Board of Directors may modify, amend, or terminate the Plan at any time
except that, to the extent then required by applicable law, rule, or regulation,
approval of the holders of a majority of shares of Common Stock represented in
person or by proxy at a meeting of the shareholders will be required to increase
the maximum number of shares of Common Stock available for distribution under
the Plan (other than increases due to adjustments in accordance with the Plan).
No modification, amendment, or termination of the Plan shall adversely affect
the rights of a Participant under a grant previously made to him without the
consent of such Participant.

               ARTICLE IX - EFFECTIVE DATE AND DURATION OF PLAN

9.1 EFFECTIVE DATE AND DURATION OF PLAN

  The Plan shall become effective immediately upon the approval and adoption
thereof at the Annual Meeting of the shareholders on April 26, 1993. All rights
granted under the Plan must be granted within ten years from its adoption date
by the shareholders of the Company. Any rights outstanding ten years after the
adoption of the Plan may be exercised within the periods prescribed under or
pursuant to the Plan.

                               REVISED SCHEDULE


The Company has entered into substantially similar agreements with certain
officers, including its Executive Officers, who are employees of Armstrong World
Industries, Inc., other than Ulrich J. Weimer, Edward R. Case, E. Follin Smith
and Dr. Bernd F. Pelz. Floyd F. Sherman's agreement has been modified to reflect
that he does not participate in the Company's defined benefit retirement plan or
its split-dollar life insurance plan and his benefits under his agreement have
been modified accordingly.

                                   Foreword

         Effective January 1, 1998, Armstrong World Industries, Inc. has adopted
the Bonus Replacement Retirement Plan of Armstrong World Industries, Inc. (the
"Plan") for the benefit of certain of its employees.

         The Plan hereinafter set forth has been approved by the Board of
Directors of Armstrong World Industries, Inc. and is intended to conform to the
requirements of the Employee Retirement Income Security Act of 1974, as amended,
and to qualify as a profit sharing plan under Section 401(a) of the Internal
Revenue Code of 1986, as amended, or any other applicable sections thereof.

         The rights to benefits of any eligible employee whose employment
terminates prior to any amendment to the Plan shall be determined solely by the
provisions of the Plan under which such eligible employee is covered, if any, as
in effect at the time of such termination of employment, unless otherwise
specifically provided herein.

<PAGE>
 
     (a)  An Employee shall be credited with Hours of Service during periods for
which he is directly or indirectly paid by, or entitled to payment from, the
Company or an Affiliated Company for the performance of duties;

     (b)  An Employee shall be credited with Hours of Service during periods
when no duties are performed:

          (1)  Due to vacation, holiday, layoff, or leave of absence, and during
which he is paid or entitled to payment by the Company or an Affiliated Company.

          (2)  Because of temporary total disability due to sickness, injury, or
incapacity, for which he receives or is entitled to receive either disability
benefits or Worker's Compensation, directly or indirectly from the Company or an
Affiliated Company.

          (3)  Due to total or total and permanent disability for which he
receives or is entitled to receive benefits under a long-term disability income
plan maintained by the Company or an Affiliated Company or under the provisions
of Article VI, Section (8) of the Retirement Income Plan for Employees of
Armstrong World Industries, Inc.

     (c)  An Employee shall be credited with Hours of Service during periods he
is absent from the service of the Company or an Affiliated Company due to jury
duty or military duty in the Armed Forces of the United States, expiring with
the expiration of any reemployment rights protected by law.

     (d)  An Employee shall be credited with Hours of Service during periods for
which back pay, irrespective of mitigation of damages, has been awarded or
agreed to by the Company or an Affiliated Company. Provided, however, that no
credit shall be given under this Section 1.14 during the period for which
payment is made solely to comply with unemployment compensation laws or for
which payment is made solely to reimburse an Employee for medical or medically-
related expenses incurred by the Employee or for the period following
retirement.

     (e)  The Committee shall determine whether an Employee is entitled to
credit for an Hour of Service on the basis of records of hours worked and
payments made or due. A salaried Employee shall be credited with 45 Hours of
Service for each week for which it is determined that he is entitled to credit
for at least one such Hour of Service.

     (f)  Hours of Service credited under Section (b), (c) or (d) hereof for a
period during which an Employee is not performing duties but for which he is
paid or entitled to payment, directly or indirectly, by the Company or an
Affiliated Company shall be subject to the following rules:

          (1)  If payments made for a period of absence are computed with
specific reference to units of time, the number of Hours credited shall be the
number of regularly scheduled working hours included in the units of time on the
basis of which the payment is

                                      -3-
<PAGE>
 
calculated, consistently determined with respect to all Employees within the
same job classification.

          (2)  If payments made for a period of absence are computed without
regard to units of time, the number of Hours of Service credited shall be equal
to the amount of the payment made with respect to such period of absence divided
by the Employee's most recent hourly rate of pay or its equivalent.

          (3)  Hours of Service credited hereunder for an absence shall be
credited to the calendar year during which the period of absence occurs;
provided, however, that if the period of absence falls within more than one
calendar year, the Committee, following uniform rules and governmental
regulations, may prorate such Hours between such calendar years. Hours of
Service credited by reason of an award or agreement to pay back pay shall be
credited to the calendar year to which the award or agreement pertains.

          (4)  The Hours of Service credited hereunder for any period of absence
shall not exceed the number of working hours regularly scheduled for the
performance of duties during such period of absence, as determined in accordance
with procedures consistently applied by the Committee with respect to all
Employees within any one job classification. No more than 501 Hours of Service
shall be credited by reason of an award or agreement to pay back pay. Nothing
contained herein shall result in double credit for the same period.

     (g)  The number of Hours of Service credited under the Plan for military
service or for any other period described in Section (c) hereof during which an
Employee is not paid or entitled to payment directly or indirectly from the
Company or an Affiliated Company shall be determined on the basis of the number
of regularly scheduled hours the Employee was working prior to the absence.

     (h)  An Employee who is absent from work due to the pregnancy of the
Employee, the birth of a child of the Employee, the placement of a child with
the Employee in connection with the adoption of such child by the Employee, the
caring for such child for the period immediately following birth or placement, a
leave of absence under the Family and Medical Leave Act of 1993, as it may be
amended from time to time, and who is not entitled to credit for such absence
under any of the other provisions of this Section 1.14 shall be credited with a
number of Hours of Service for such absence equal to the number of Hours of
Service that would have been credited to the Employee had he been performing
duties during the absence or, if the Committee is unable to determine the number
of such Hours, eight (8) Hours of Service per day of such absence; provided,
however, that in no event shall more than 501 Hours of Service be credited for
any single continuous period of absence described in this Section 1.14(h). If in
the year in which the absence begins, the Employee has not yet been credited

     (b)  If and when a suspended Member again becomes employed by the Company

     2.3  Beneficiary Designation - Subject to the rules set forth below with
          -----------------------
respect to married Members, each Member has the right to name a Beneficiary to
receive any death benefits payable hereunder. Each Member also has the right,
from time to time, to change any designation of Beneficiary. A designation or
change of Beneficiary must be in writing on forms supplied by the Committee and
any change of Beneficiary will not become effective until such change of
Beneficiary is filed with the Committee or its designee whether or not the
Member is alive at the time of such filing; provided, however, that any such
change will not be effective with respect to any payments made by the Trustee in
accordance with the Member's last designation and prior to the time such change

the case of any Member who is married on the date of his death, the Member's
spouse as of his date of death shall be his Beneficiary unless such spouse shall
have consented to a different Beneficiary on prescribed forms and before either
a notary public or an individual designated by the Committee. Such spousal
consent must acknowledge the effect of the Beneficiary designation. In the
absence of an effective Beneficiary designation or if a named Beneficiary shall
have died and no contingent Beneficiary shall have been properly designated, the
first of the following classes of successive preference beneficiaries shall be
the Beneficiary:

         (a)   the Member's surviving spouse;

         (b)   the Member's surviving children;

Any individual who is designated as an alternate payee under a "qualified
domestic relations order" (as defined in Code Section 414(p)) relating to a
Member's Account under this Plan shall be treated as a Beneficiary hereunder, to
the extent provided by such order. The Committee may require and rely upon such
proof of death and such evidence of the right of any Beneficiary or other person
to receive the undistributed value of a deceased Member's Account as the
Committee may deem proper, and its determination of death and of the right of
such Beneficiary or other person to receive payment shall be conclusive.

such Member for the Plan Year shall be equal to the lesser of (i) 50% of the
actual "gross bonus" (as such term is defined under the Company's Management
Achievement Plan) awarded to the Employee under the Company's Management
Achievement Plan with respect to services performed by the Member for the
Company for the calendar year coinciding with such Plan Year, or (ii) $7,500.

          (2)  If a Member's employment grade is at least grade 1,460 but not

Achievement Plan with respect to services performed by the Member for the
Company for the calendar year coinciding with such Plan Year, or (ii) $15,000.

          (3)  If a Member's employment grade is at least grade 1,930 under the

coinciding with such Plan Year, or (ii) $20,000.

     (b)  Allocation and Payment to Trust - Company Contributions for a Plan
          -------------------------------
Year shall be allocated to the Members' Accounts as of the last day of the Plan
Year for which such contributions are made. Company Contributions for any Plan
Year shall be paid to the Investing Institution not later than the date which is
prescribed by law for filing the Company's income tax return, including any
extension thereof.

     (c)  Additional Company Contributions or Reallocations Permitted to
          --------------------------------------------------------------
Correct Administrative Error - If, with respect to a Plan Year, an
- ----------------------------
administrative error results in a Member's Account not being properly credited
with the amount of Company Contributions, or earnings on such contributions,
corrective Company Contributions or Account reallocations may 

                                      -8-

be made in accordance with this subsection. Solely for the purpose of placing
any affected Member's Account in the position that it would have been in if no
error had been made:

          (1)    The Company may make additional contributions to such Member's
Account; or

          (2)    The Committee may reallocate existing Company Contributions 
made under Section 3.1 among the Accounts of affected Members.

     3.2  Return of Contributions - All Company Contributions are conditioned
          -----------------------
on their being allowed as a deduction for federal income tax purposes.
Notwithstanding any provision of the Plan to the contrary, Company Contributions
made to the Plan may be returned to the Company if:

     (a)  the contribution is made by reason of mistake of fact; or

     (b)  the contribution is conditioned on its deductibility under Code
Section 404 and such deductibility is denied;

provided such return of contribution is made within one year of the mistaken
payment of the contribution or the disallowance of the deduction, as the case
may be. A contribution shall be considered to be made by reason of a mistake of
fact if, for example, it is based on incorrect information as to eligibility or
compensation of an Employee, a mathematical error or an erroneous belief that
such contribution is consistent with the limitations of Section 11.1. So much of
the contribution as is attributable to the mistake of fact shall be repaid by
the Trustee upon demand by the Company upon presentation of evidence of the
mistake of fact and calculation as to the impact of the mistake.

     3.3  Vesting of Member's Account and Forfeitures - A Member shall have a
          -------------------------------------------
vested and nonforfeitable interest in his Account upon (a) his completion of
five (5) Years of Continuous Employment, (b) his death, (c) his retirement, (d)
the sale of substantially all of the assets of a trade or business, unit or
location where the Member is employed, (e) the sale by the Company of its
interest in a subsidiary where the Member is employed, or (f) the transfer of
the Member to employment with WAVE, a Delaware general partnership. If a
Member's Continuous Employment is terminated prior to the time such Member has a
nonforfeitable interest in his Account, the amount in such Member's Account
shall be forfeited. If a former Member resumes employment with the Company or an
Affiliated Company, the amount forfeited shall be restored (without earnings) to
his Account.

     Amounts forfeited under this Section shall be used, not later than as of
the last day of the Plan Year in which the forfeiture occurs, to reduce future
Company Contributions, to defray administrative expenses of the Plan, and to
restore Members' Accounts in accordance with the preceding paragraph of this
Section.

               ----------------------------
elections pursuant to Section 4.2 at any time with respect to any subsequent

prescribed by the Committee.

         4.4   Transfer Between Funds -

portion of the value of his Account in one of the Investment Funds to any other
Investment Fund at the following times (and under such uniform rules as the
Committee may adopt from time to time):

               (1) Any election to transfer between and among the Equity

Balanced Fund (and any related funds maintained in the Equity Investment Fund,
the Fixed Income Investment Fund, the Money Market Fund and the Balanced Fund)
may be made at any time, to be effective as soon as practicable thereafter; and

               (2) Any election to transfer to or from the Company Stock Fund

selection of his investment option. The Investing Institutions, the Committee,
the Company or any of the officers or supervisors of the Company are not
empowered to advise a Member as to the manner in which his Account shall be
invested. The fact that a security is available to Members for investment under
the Plan shall not be construed as a recommendation for the purchase of that
security, nor shall the designation of any option impose any liability on the
Company, its directors, officers or employees, the Investing Institutions, the
Committee or any Member of the Plan.

value of which is allocated to Members' Accounts, shall be voted by the Trustee
of the Trust, in accordance with instructions from the Members. The Company
shall provide Members with notices and information statements when voting rights
are to be exercised, the content of which must generally be the same as for all
holders of interests in Company stock. Fractional shares may be voted by the
Trustee on a combined basis, in order to reflect the direction of the Members
holding such shares. The Trustee shall tabulate the instructions and shall
determine the ratio of votes for and against each proposition. The Trustee shall
then vote all stock held by it, including stock for which no instructions have
been received, in the ratios determined by the vote of those Members who
returned voting instructions.

         (b)   Tender Offer Procedure - In the event any offer is made to
               ----------------------
shareholders of the Company generally by any person corporation or other entity
(the "Offeror") to purchase any or all of the Company's outstanding stock
including the stock the value of which is then held in Members' Accounts, then
and in that event the Trustee shall promptly forward to each Member 

                                      -12-
<PAGE>
 
all materials and written information furnished to the Trustee by the Offeror
and/or by the Company in connection therewith, and shall notify each Member in
writing of the number of shares of Company stock the value of which is then
credited to such Member's Account. Such notice shall also set forth the rights
afforded each Member by the following sentence and shall state that, absent
timely instructions from such Member to the Trustee, no tender to the Offeror
shall be made of any of the shares specified in such written notice. Each Member
shall be entitled to instruct the Trustee as to whether all (but not less than
all) of the shares of Company stock standing to his credit should be tendered by
the Trustee pursuant to such offer.

         (c)   Shares Tendered - The Trustee shall tender only those shares of
               ---------------
Company stock the value of which is held in a Member's Account for which it
receives instructions to so tender from such Member and shall not tender any
shares as to which such instructions are not so received.

         (d)   Proceeds - In the event that Company stock the value of which is
               --------
held in a Member's Account is tendered, the proceeds received upon the
acceptance of such tender by the Offeror shall be credited to such Member's
Account. The Trustee shall invest amounts representing the proceeds of tendered
Company stock and any earnings thereon, in accordance with instructions from the
Committee.

         4.7   Limitations - Provisions of this Article are subject to the 
               -----------
limitations of any contract with any Investing Institution.

                        VALUATION OF A MEMBER'S ACCOUNT
                        -------------------------------

         "Valuation Date" shall mean any day that the New York Stock Exchange is
open for trading or such other date as may be designated by the Committee or its
delegate. The Investment Funds described in Section 4.1 shall be valued on each
Valuation Date in accordance with rules established by the Committee. Whenever a
distribution to a Member is made, the amount paid to the Member shall be based
on the value of the Member's Account determined as of the Valuation Date set
forth in Article VI.

         Each Member's Account will be credited, as of the Valuation Date on
which such amounts are received by the Trustee, with all contributions made on
the Member's behalf and debited with the amount of any distribution made to the
Member or on the Member's behalf pursuant to Article VI. The Account of each
Member will also be adjusted, as of each Valuation Date, for increases
reflecting the Member's share of the net investment income and any realized and
unrealized capital gains of the Funds and decreases reflecting the Member's
share of any realized and unrealized losses, including capital losses, as well
as the payment of brokerage fees and transfer taxes applicable to purchases and
sales for each Investment Fund and all similar transactions, and any Plan
administrative expenses to the extent they are not paid by the Company, of the
Investment Funds that occurred since the last Valuation Date. Except to the
extent otherwise reflected in the value of mutual fund shares, such Member's
share of such income and losses will be that portion of the total net investment
income, capital gains and losses of each such Investment Fund which bears the
same ratio to such total as the balance of his Member Accounts attributable to
each such Investment Fund on the preceding Valuation Date bears to the aggregate
of the balances of all Member Accounts attributable to each such Investment Fund
as of the preceding Valuation Date.

         (a)   A Member whose Continuous Employment is terminated prior to the
date such Member has a nonforfeitable interest in his Account in accordance with
Section 3.3 shall not be entitled to any benefits under the Plan, and instead
shall be deemed to have received a distribution of zero dollars upon his
termination of Continuous Employment; provided that if such Member is reemployed
by the Company or an Affiliated Company, such Member shall be deemed to have
repaid such zero dollar distribution.

         (b)   Subject to Section 6.4, if a Member terminates employment for any
reason other than death, he may elect (in the manner specified by the Committee)
at any time following his termination to receive a single sum cash payment of
the nonforfeitable portion of his Account as soon as practicable following the
Committee's receipt of the Member's election.

         (c)   If a Member is eligible to receive a distribution in accordance
with subsection (b), he may request in the manner prescribed by the Committee
(including telephonically) to have such distribution paid directly to him or
paid as a "direct rollover distribution" (as defined in Code Section 402(c) and
the regulations and other guidance issued thereunder).

         (d)   The amount of such distribution shall be determined as follows:
for any request made by the fifteenth day of the month, the amount of such
distribution shall be determined as of the next Valuation Date following the
fifteenth day of the month; for any request made after the fifteenth day of the
month and by the last day of the month, the amount of such distribution shall be
determined as of the next Valuation Date following the last day of the month.
For purposes of the preceding sentence, if the fifteenth or last day of a month
falls on a Saturday, Sunday or holiday, the fifteenth or last day of such month
shall be deemed to be the last business day preceding the fifteenth or last day,
respectively.

         (e)   Notwithstanding subsection (b), the portion of the Member's
Account that is invested in the Company Stock Fund shall be distributed in a
single sum in either cash or Company Stock (with cash for fractional shares), as
elected by the Member. If the Member fails to elect, prior to the time the time
such distribution is to be processed pursuant to the Member's election or
pursuant to the requirements of Section 6.4, to receive the portion of his
Account invested in the Company Stock Fund in shares of Company Stock, such
distribution shall be made in cash.

         (f)   The Committee or its designee shall notify each Member, at such
time and in such manner as required by Sections 402(f) and 411(a)(11) of the
Code and the regulations and other guidance issued thereunder, of his right to
make a "direct rollover distribution," in accordance 

                                      -15-
<PAGE>
 
with Section 6.5 below, and his right to receive a distribution of his Account
under this Section 6.1. Distribution of a Member's Account under the Plan may
occur prior to 30 days after the Committee or its designee provides such notice,
provided:

               (1)  the Member is informed that he has a right to a period of at
least 30 days after receiving the notice to consider the decision of whether to
make a direct rollover distribution and whether to receive an immediate
distribution; and

               (2)  the Member, after receiving the notice, requests to receive
an immediate distribution in the manner prescribed by the Committee (including
telephonically).

         6.2   Distribution Upon a Member's Death -
               ----------------------------------

         (a)   In the event a Member dies prior to his receipt of a distribution
under Section 6.1, the entire value of his Account shall be paid in a single sum
cash payment to the Member's Beneficiary as soon as practicable following
receipt of proper payment instructions by the Trustee from the Committee. The
amount of such distribution shall be determined in accordance with Section
6.1(d), substituting "for payment instructions received" for the phrase "for any
request made" in such section. The Committee shall provide the Trustee payment
instructions as soon as practicable after the Member's death or notification of
the Member's death, if later. No benefits shall be payable under this Section
6.2 to any Beneficiary if the Member dies after commencing to receive a
distribution of his Accounts.

         (b)   Notwithstanding the foregoing, if the Member's Beneficiary is the
Member's spouse, such Beneficiary may elect to defer receipt of the single sum
payment beyond the date on which it normally would become payable, but in no
event later than December 31 of the calendar year in which the Member would have
attained age 70 1/2.

         (c)   In no event may a Beneficiary elect to receive a payment of a
Member's Account in any form of payment other than a single sum payment.
Further, if a spousal Beneficiary defers distribution of any amounts from the
Plan, then prior to the distribution of such Account, the Beneficiary may not
obtain any partial distributions. However, such Beneficiary may continue to
invest amounts in the Member's Account in accordance with Article IV.

         (d) Notwithstanding subsection (a), the portion of the Member's Account
that is invested in the Company Stock Fund shall be distributed in a single sum
in either cash or Company Stock (with cash for fractional shares), as elected by
the Beneficiary. If the Beneficiary fails to elect to receive the portion of the
Member's Account invested in the Company Stock Fund in shares of Company Stock,
such distribution shall be made in cash.

         6.3   Lost Members or Beneficiaries - If a Member or Beneficiary cannot
               -----------------------------
be located by reasonable efforts of the Committee within a reasonable period of
time after the latest date such benefits are otherwise payable under the Plan,
the amount in such Member's Account shall be forfeited and used to reduce future
Company Contributions, defray administrative expenses of the Plan, and restore
Members' Accounts in accordance with this section; provided, however, that

                                      -16-
<PAGE>
 
such forfeited amount shall be restored (without earnings) if, at any time, the
Member or Beneficiary who was entitled to receive such benefit when it first
became payable shall, after furnishing proof of his identity and right to make
such claim to the Committee, file a written request for such benefit with the
Committee.

         6.4   Required Distributions -
               ----------------------

         (a)   Notwithstanding anything to the contrary in this Plan, unless the
Member elects otherwise, in writing, payments under the Plan to a Member shall
begin not later than the 60th day after the latest of the close of the Plan Year
in which:

               (1)  the Member attains age 65;

               (2)  occurs the tenth anniversary of the year in which the Member
commences participation in the Plan; or

               (3)  the Member terminates employment.

         (b)   All payments under this Plan shall be adjusted to meet the
requirements of Section 401(a)(9) of the Code and the regulations and other
guidance issued thereunder, subject to the provisions of this Section 6.4. In
addition, all distributions under the Plan shall comply with the incidental
death benefit requirements of Section 401(a)(9)(G) of the Code.

         (c)   Payment of benefits to any Member who is not a 5% owner as
defined in Code Section 416 shall be paid in the form of a lump sum payment not
later than the April 1 following the later of: (i) the calendar year in which
such Member attains age 70 1/2, or (ii) the calendar year in which such Member
terminates employment. Payment of benefits to any Member who is a 5% owner as
defined in Code section 416 shall be paid in the form of a lump sum payment not
later than the April 1 following the calendar year in which such Member attains
age 70 1/2.

         6.5   Direct Rollover Distributions - At the request of a Member, a
               -----------------------------
surviving spouse of a Member, or a spouse or former spouse of a Member that is
an alternate payee under a qualified domestic relations order under Section 10.5
(referred to as the "distributee") and upon receipt of the direction of the
Committee or its designee, the Trustee shall effectuate a direct rollover
distribution of the amount requested by the distributee, in accordance with Code
Section 401(a)(31), to an eligible retirement plan (as defined in Code Section
402(c)(8)(B)). Such amount may constitute all or any whole percent of any
distribution from the Plan otherwise to be made to the distributee, provided
that such distribution constitutes an "eligible rollover distribution" as
defined in Code Section 402(c) Code and the regulations and other guidance
issued thereunder. All direct rollover distributions shall be made in accordance
with the following subsections (a) through (d):

         (a)   A direct rollover distribution may only be made to one eligible
retirement plan; a distributee may not elect to have a direct rollover
distribution apportioned between or among more than one eligible retirement
plan.

                                      -17-
<PAGE>
 
         (b)   Direct rollover distributions shall be made in cash to the
Trustee of the eligible retirement plan, in accordance with procedures
established by the Committee, plus shares of common stock otherwise
distributable under the Plan to the distributee, which shares shall be
registered in a manner necessary to effectuate a direct rollover under Code
Section 401(a)(31), provided, however, that the distributee may request that
such direct rollover distribution be made entirely in cash in the manner
described above.

         (c)   No direct rollover distribution shall be made unless the
distributee furnishes the Committee with such information as the Committee shall
require and deems to be sufficient.

         (d)   Direct rollover distributions shall be treated as all other
distributions under the Plan and shall not be treated as a direct
trustee-to-trustee transfer of assets and liabilities.

         6.6   Distributions on Sales of Businesses - For the sole purpose of
               ------------------------------------
determining a Member's entitlement to a distribution under this Plan, no
distribution shall be permitted upon the sale or other business disposition by
the Company of a trade or business or the sale by the Company of its interest in
a subsidiary, with respect to a Member who is employed by such trade or business
or subsidiary immediately prior to such sale or disposition and who continues in
the employ of (i) the employer that acquires the assets of such trade or
business or acquires the interest of such subsidiary or (ii) any other entity
related to such employer.

         6.7   Payments to Minors and Incompetents - If a Member or Beneficiary
               -----------------------------------
entitled to receive any benefits hereunder is a minor or is deemed by the
Committee or is adjudged to be legally incapable of giving valid receipt and
discharge for such benefits, they will be paid to such persons as the Committee
might designate or to the duly appointed guardian. Any such payment shall be a
complete discharge of the liability of the Plan and the Trust therefor.

                              -------------------

         7.1   General Responsibilities - All the funds of the Plan shall be
               ------------------------
held by a Trustee or Trustees appointed from time to time by the Board of
Directors, in one or more trusts under a trust instrument or instruments
approved or authorized by the Board of Directors for use in providing the
benefits of the Plan; provided that no part of the corpus or income of the Trust
Fund shall be used for, or diverted to, purposes other than for the exclusive
benefit of Members and their Beneficiaries.

         7.2   Funding Agreements -
               ------------------

         (a)   All the funds of the Plan shall be held by one or more Investing
Institutions appointed from time to time by the Company under a Trust Agreement
or an Insurance Contract adopted, or as amended, by the Company for the
administration of the funds of the Plan. The Company shall have no liability for
the investment of the funds paid over to the Investing Institution.

         (b)   The Company retains the right to act on behalf of all persons
having an interest in any Trust Fund or under any Insurance Contract, and to
enter into additional Trust Agreements or Insurance Contracts.

         7.3   Investment Managers - The Committee may appoint one or more
               -------------------
Investment Managers to manage the investment of all or any part of one or more
of the Investment Funds. Every Investment Manager so appointed must meet the
requirements of ERISA Section 3(38). An Investment Manager shall acknowledge in
writing its appointment as a fiduciary of the Plan, and shall serve until a
proper resignation is received by the Committee, or until it is removed and/or
replaced by the Committee. The Committee and the Trustee shall be under no duty
to question any direction or lack of direction of any Investment Manager, but
shall act, and shall be fully protected in acting, in accordance with each such
direction. An Investment Manager shall have sole investment responsibility for
that portion of the Funds which it is appointed to manage, and no other Plan
fiduciary shall have any responsibility for the investment of any asset of the
Fund, the management of which has been delegated to an Investment Manager, or
liability for any loss or diminution in value of the Fund resulting from any
action directed, taken or omitted by an Investment Manager.

                          Administration of the Plan
                          --------------------------

         8.1   The Committee - The administration of this Plan, the exclusive
               -------------
power to interpret and construe it and the responsibility for carrying out its
provisions, shall be vested in the Committee, which shall consist of the same
persons as constitute the Retirement Committee of the Retirement Income Plan for
Employees of Armstrong World Industries, Inc. The Chairman and Secretary of the
Retirement Income Plan's Committee shall be the Chairman and Secretary of this
Committee. In the event no members of the Committee are in office, the Company
shall be deemed the Committee.

         8.2   Duties of the Committee - The members of the Committee may
               -----------------------
appoint from their number such subcommittees with such powers as they shall
determine; may authorize one or more of their number or any agent to execute or
deliver any instrument or make any payment on their behalf; may retain counsel,
employ agents and provide for such clerical, accounting and consulting services
as they may require in carrying out the provisions of the Plan; and may allocate
among themselves or delegate to other persons all or such portion of their
duties hereunder, other than those granted to any Investment Manager pursuant to
Section 7.3 or the Trust agreement adopted for use in implementing the Plan, as
they, in their sole discretion shall decide.

         8.3   Meetings - The Committee shall hold meetings upon such notice, at
               --------
such place or places, and at such time or times at it may from time to time
determine.

         8.4   Action by Majority - Any act which the Plan authorizes or
               ------------------
requires the Committee to do may be done by a majority of its members. The
action of such majority expressed from time to time by a vote at a meeting or in
writing without a meeting shall constitute the action of the Committee and shall
have the same effect for all purposes as if assented to by all members of the
Committee at the time in office.

         8.5   Compensation - No member of the Committee shall receive any
               ------------
compensation from the Plan for his services as such. However, all expenses of
the Committee shall be paid by the Company.

         8.6   Establishment of Rules - Subject to the provisions of any
               ----------------------
Insurance Contract and the limitations of the Plan, the Committee from time to
time shall establish rules for the administration of the Plan and the
transaction of its business. The Committee shall have the full and exclusive
discretionary authority to interpret the Plan, to determine all benefits and to
resolve all questions arising from the administration, interpretation, and
application of Plan provisions, either by general rules or by particular
decisions, including determinations as to whether a claimant is eligible for
benefits, the amount, form and timing of benefits, and any other matter
(including any question of fact) raised by a claimant or identified by the
Committee. All decisions of the Committee shall be conclusive and binding upon
all affected persons.

         8.7   Prudent Conduct - The members of the Committee shall use that
               ---------------
degree of care, skill, prudence and diligence that a prudent man acting in a
like capacity and familiar with such 

                                      -20-
<PAGE>
 
matters would use in his conduct of a similar situation. A member of the
Committee shall not be liable for the breach of fiduciary responsibility of
another fiduciary unless (a) he participates knowingly in, or knowingly
undertakes to conceal, an act or omission of such other fiduciary, knowing such
act or omission is a breach; or (b) by his failure to discharge his duties
solely in the interest of the Members and Beneficiaries for the exclusive
purpose of providing their benefits and defraying reasonable expenses of
administering the Plan not met by the Company, he has enabled such other
fiduciary to commit a breach; or (c) he has knowledge of a breach by such other
fiduciary and does not make reasonable efforts to remedy the breach; or (d) the
Committee improperly allocates responsibilities among themselves or improperly
delegates responsibilities to others, or fails to properly review any allocation
or delegation of fiduciary responsibilities.

         8.8   Indemnification - The Company will indemnify and save harmless
               ---------------
the members of the Committee and any person to whom fiduciary responsibilities
are delegated under this Plan against any cost or expense (including attorney's
fees) or liability (including any sum paid in settlement of a claim with the
approval of the Company) arising out of any act or omission to act, except in
the case of willful misconduct.

                           Amendment and Termination
                           -------------------------

         This Plan may be terminated, modified, altered or amended by the
Retirement Committee by resolution at any time, provided that no such
termination, modification, alteration or amendment shall cause or permit the
Trust Fund to be used for, or diverted to, any purposes other than for the
exclusive benefit of the employees of the Company included in this Plan. In no
case shall any amendment of this Plan cause the reduction or elimination of any
Member's accrued benefit (including optional forms of benefit and the manner and
timing thereof) in violation of Code Section 411(d)(6) or ERISA Section 204(g).
Notwithstanding the foregoing, any modification or amendment of the Plan may be
made, retroactively if necessary, which the Retirement Committee or its delegate
deems necessary or proper to bring the Plan into conformity with any law or
governmental regulation relating to plans or trusts of this character, including
the qualification of any trust or other fund created under the Plan as exempt
from income taxes under the Code. Further, notwithstanding the foregoing, in the
event of the complete or partial termination of the Plan (which partial
termination shall occur only in the event of a reduction of a substantial number
or percentage of participants due to employer-initiated actions, as determined
in accordance with applicable law), or the complete discontinuance of
contributions thereto, the Account balances of all affected Members shall become
fully vested. The Account balance of each affected Member shall continue to be
held in trust until the Member is entitled to a distribution under Article VI.

         10.1  Expenses - All costs and expenses in administering the Plan and
               --------
managing the Trust Fund shall be paid from the Trust Fund and charged within the
Trust Fund to the appropriate Investment Funds to which such costs and expenses
are attributable to the extent such expenses are not paid by the Company.
Notwithstanding the foregoing, brokerage fees, commissions, stock transfer taxes
and other charges and expenses in connection with the purchase and sale of
securities shall be paid from the Trust Fund and charged within the Trust Fund
to the Investment Fund to which such charges and expenses are attributable.

         10.2  Source of Payment - Benefits under the Plan shall be payable only
               -----------------
out of the Trust Fund and the Company shall not have any legal obligation or
liability to make any direct payment of benefits under the Plan. Neither the
Company nor the Trustee guarantees the Trust Fund against any loss or
depreciation, or guarantees the payment of any benefit hereunder. No persons
shall have any rights under the Plan with respect to the Trust Fund, or against
the Trustee or the Company, except as specifically provided for herein.

         10.3  No Right of Employment - Nothing contained in the Plan shall be
               ----------------------
deemed to give any employee the right to be retained in the service of the
Company or to interfere with the right of the Company to discharge or to retire
any employee at any time.

         10.4  Non-Alienation of Benefits - Except as specifically provided in
               --------------------------
the Plan, no benefit payable at any time under this Plan shall be subject in any
manner to alienation, sale, transfer, assignment, pledge, attachment or
encumbrance of any kind. Any attempt to alienate, sell, transfer, assign,
pledge, attach or otherwise encumber any such benefit, whether presently or
thereafter payable, shall be void. Neither any benefit, nor the Trust Fund
shall, in any manner, be liable for or subject to the debts or liability of any
employee included in this Plan or any beneficiary. If any employee included in
this Plan or any Beneficiary shall attempt to or shall alienate, sell, transfer,
assign, pledge, attach or otherwise encumber his rights or benefits under this
Plan or any part thereof, or if by reason of bankruptcy or otherwise the rights
or benefits of any employee included in this Plan or of any beneficiary would
devolve upon anyone else or would not be enjoyed by him, then the Committee, in
its discretion and to the extent permitted by law, may terminate his interest in
any such right or benefit and direct the Trustee to hold or apply it for his use
or account or for the use or account of his spouse, children, or other
dependents or any of them in such manner as the Committee may deem proper.

         10.5  Qualified Domestic Relations Orders - Notwithstanding any
               -----------------------------------
provision in the Plan to the contrary, the Committee shall take such steps as
are necessary under the Plan to comply with the terms of any applicable
"qualified domestic relations order" (as defined by Code Section 414(p) and
ERISA Section 206(d)). The Account of any Member subject to such an order shall
be adjusted to reflect any payments made pursuant to such order. Payments may be
made from this Plan pursuant to such an order at any time prior to earliest
retirement age, as defined in the Code and ERISA. The Committee shall adopt such
procedures as it deems necessary and appropriate to carry out the provisions of
this Section.

         10.6  Invalidity of Provisions - If any provision of this Plan is held
               ------------------------
invalid or unenforceable, such invalidity or unenforceability shall not affect
any other provisions hereof, and this Plan shall be construed and enforced as if
such invalid or unenforceable provision had not been included.

         10.7  Failure to Initially Qualify Plan - In no event shall any part of
               ---------------------------------
the corpus or the income of the Plan be used for, or diverted to, any purpose
other than the exclusive benefit of Members, former Members and their
Beneficiaries hereunder. Notwithstanding the foregoing, in the event that the
Internal Revenue Service initially determines that the Plan does not qualify
under Code Section 401(a), all Company Contributions made prior to such initial
determination as to the qualification of the Plan may be returned to the Company
within one year of the denial of qualification.

         10.8  Adoption of Plan by Subsidiary, Affiliated or Associated Company
               ----------------------------------------------------------------
- - The Company may, by resolution of the Board of Directors, exclude from
participation in this Plan any or all of the Employees of the Company or an
Affiliated Company. Any subsidiary company of the Company may, by action of its
board of directors with the approval of the Board of Directors of the Company,
adopt this Plan with respect to its Employees. The Company may, by resolution of
the Board of Directors, or by action of the appropriate officers of the Company,
make this Plan applicable to any Employees of the Company or an Affiliated
Company. With respect to any such Employees to which this Plan is made
applicable, Effective Date refers to the date as of which the Plan is made
applicable to such Employees. The Committee shall adopt such procedures as it
deems necessary and appropriate to carry out the provisions of this Section.

         10.9  Mergers and Transfers - No merger or consolidation with, or
               ---------------------
transfer of assets or liabilities to, any profit sharing or retirement plan,
shall be made unless the benefit each Member in this Plan would receive if the
Plan were terminated immediately after such merger or consolidation, or transfer
of assets and liabilities, would be at least as great as the benefit he would
have received had the Plan terminated immediately before such merger,
consolidation or transfer.

         10.10 Compliance with Securities Laws - Any other provisions in this
               -------------------------------
Plan to the contrary notwithstanding, purchase or distribution of Company common
stock shall be subject to compliance with any applicable federal or state
securities laws or rules and regulations thereunder.

         10.11 Governing Law - To the extent such laws are not preempted by
               -------------
ERISA, the provisions of the Plan shall be interpreted in accordance with the
laws of the Commonwealth of Pennsylvania.

         10.12 Trust-to-Trust Transfers - In the event of a transfer from a
               ------------------------
qualified plan (other than a plan subject to the requirements of Section 417 of
the Code), and at the discretion of the Committee, and pursuant to procedures
issued by the Committee, the individuals who were participants in such other
plan may be given the opportunity to elect to have their entire interests in
such plan transferred directly on a trust-to-trust basis into this Plan. Any
such transferred 

                                      -24-

amounts shall be allocated to Accounts of Members as determined by the

               ------------
the singular includes the plural.

         10.14 Nondiscrimination Testing - For purposes of satisfying the
               -------------------------
nondiscrimination requirements under Code Section 401(a)(4), the term "highly
compensated employee" shall mean an Employee of the Company or an Affiliated
Company who:

               (a)  was a 5% owner, as defined in Section 416(i)(1) of the Code,

         Notwithstanding the foregoing, the Committee may make a "top-paid
group" election under the regulations or other guidance issued pursuant to
Section 414(q) of the Code with respect to any preceding year. If such election
is made, the foregoing provisions of subsection (b) shall be applied in
accordance with such election. The "top-paid group" shall include all Employees

following Employees shall be excluded: (i) Employees who have not completed six

Regulation section 1.415-2(d)(11)(i)) or (2) the dollar limit in effect for such
calendar year in accordance with Code Section 415(c)(1)(A).

         (b)   For purposes of this Section 11.1, the term "Annual Addition"
with respect to any Member means the Company Contributions made pursuant to
Section 3.1 allocated to the Member's Account and amounts described in Code
Sections 415(l)(1) and 419A(d)(2).

         (c)   If a Member is also participating in another tax-qualified
defined contribution plan maintained by the Company or an Affiliated Company (as
modified by application of Code Section 415(h)), the otherwise applicable
limitation on Annual Additions under this Plan shall be reduced by the amount of
annual additions (within the meaning of Code Section 415(c)(2)) under any such
other defined contribution plan.

         (d)   For Plan Years beginning prior to January 1, 2000, if a Member in
this Plan is a Member in any tax-qualified defined benefit plan maintained by
the Company or any Affiliated Company (as modified by application of Code
Section 415(h)), the overall limitation of Code Section 415(e) shall be complied
with by limiting the amount of contributions that may be made on behalf of a
Member under this Plan.

         (e)   Excess Company Contributions, as determined under subsections (a)
through (d) above, shall be used to reduce future Company Contributions on
behalf of the Member for the next succeeding Limitation Year and succeeding
Limitation Years as necessary. If the Member is not covered by the Plan as of
the end of such succeeding year, but an excess amount still exists, such excess
amount will be held unallocated in a suspense account. The suspense account will
be applied to reduce future contributions on behalf of the other Members
entitled to an allocation, in that Limitation Year, and succeeding Limitation
Years, if necessary.

         11.2  Top-Heavy Provisions -
               --------------------
               
         (a)   Special Top-Heavy Definitions - For purposes of this Section 
               -----------------------------
11.2, the following terms shall have the following meanings:

               (1)  "Determination Date" means, with respect to any Plan Year,
the last Valuation Date of the preceding Plan Year.

               (2)  "Key Employee" means a Member or former member who is a "key

                                      -26-
<PAGE>
 
employee" as defined in Code Section 416(i).

               (3)  "Permissive Aggregation Group" means, with respect to a
given Plan Year, this Plan and all other plans of the Company and its Affiliated
Companies (other than those included in the Required Aggregation Group) which,
when aggregated with the plans in the Required Aggregation Group, continue to
meet the requirement of Code Sections 401(a)(4) and 410.

               (4)  "Present Value of Accounts" means, as of a given
Determination Date, the sum of the Members' Accounts under the Plan as of such
Valuation Date. The determination of the Present Value of Accounts shall take
into consideration distributions made to or on behalf of the Member in the Plan
Year ending on the Determination Date and the four preceding Plan Years, but
shall not take into consideration the Accounts of any Member who has not
performed any services for the Company during the five year period ending on the
Determination Date.

               (5)  "Required Aggregation Group" means with respect to a given
Plan Year, (i) this Plan, (ii) each other plan of the Company and its Affiliated
Companies in which a Key Employee is a participant (regardless of whether the
plan has terminated within the last five (5) Plan Years), and (iii) each other
plan of the Company and its Affiliated Companies which enables a plan described
in (i) or (ii) to meet the requirements of Code Sections 401(a)(4) or 410.

               (6)  "Top-Heavy" means, with respect to the Plan for a Plan Year:

                    (i)  that the Present Value of Accounts of Key Employees
exceeds 60% of the Present Value of Accounts of all Members; or

                    (ii) the Plan is part of a Required Aggregation Group and
such Required Aggregation Group is a Top-Heavy Group, unless the Plan or such
Top-Heavy Group is itself part of a Permissive Aggregation Group which is not a
Top-Heavy Group.

               (7)  "Top-Heavy Group" means, with respect to a given Plan Year,
a group of Plans of the Company which, in the aggregate, meet the requirements
of the definition contained in Code Section 416(g)(2)(B). Solely for the purpose
of determining if the Plan, or any other Plan included in a required aggregation
group of which this Plan is a part, is top-heavy (within the meaning of Code
Section 416(g)) the accrued benefit of an Employee other than a key employee
(within the meaning of Code Section 416(i)(1)) shall be determined under (1) the
method, if any, that uniformly applies for accrual purposes under all Plans
maintained by the Company, or (ii) if there is no such method, as if such
benefit accrued not more rapidly than the slowest accrual rate permitted under
the fractional accrual rate of Code Section 411(b)(1)(C).

         (b)   Special Top-Heavy Rules - Notwithstanding any other provision of
               -----------------------
the Plan to the contrary, the following provisions of this Section 11.2 shall
automatically become operative and shall supersede any conflicting provisions of
the Plan if, in any Plan Year, the Plan is Top-Heavy.

               (1)  The minimum Company Contribution during the Plan Year on
behalf of a

                                      -27-
<PAGE>
 
Member who is not a Key Employee shall be equal to the lesser of (i) 3% of such
Member's compensation (within the meaning of Section 415 of the Code); or (ii)
the percentage of compensation at which Company Contributions are made (or
required to be made) under the Plan on behalf of the Key Employee for whom such
percentage is the highest.

               (2)  In order to comply with the requirements of Code Section
416(h), in the case of a Member who is or has also participated in a defined
benefit plan of the Company (or any Affiliated Company that is required to be
aggregated with the Company in accordance with Section 415(h) of the Code) in
any Plan Year in which the Plan is Top-Heavy, there shall be imposed under such
defined benefit plan the following limitation in addition to any limitation
which may be imposed as described in Section 11.1. In any such year, for
purposes of satisfying the aggregate limit on contributions and benefits imposed
by Section 415(e) of the Code, contributions to this Plan shall, except as
hereinafter described, be reduced so as to comply with a limit determined in
accordance with Section 415(e) of the Code, but with the number "1.0"
substituted for the number "1.25" in the "defined benefit plan fraction" (as
defined in Section 415(e)(2) of the Code) and in the "defined contribution plan
fraction" (as defined in Section 415(e)(3) of the Code). Notwithstanding the
foregoing, if the application of the additional limitation set forth in this
Subsection 11.2(b) would result in the reduction of accrued benefits of any
Member under the defined benefit plan, such additional limitation shall not
become operative, so long as (i) no additional Company Contributions,
forfeitures or voluntary nondeductible contributions are allocated to such
Member's accounts under any defined contribution plan maintained by the Company
including this Plan and (ii) no additional benefits accrue to such Member under
any defined benefit plan maintained by the Company. Accordingly, in any Plan
Year that the Plan is Top-Heavy, no additional benefits shall accrue under the
defined benefit plan on behalf of any Member whose overall benefits under the
defined benefit plan otherwise would be reduced in accordance with the
limitation described in this subsection (b)(2).

               (3)  A Member who is not a Key Employee and whose employment is
terminated prior to the completion of two (2) or more Years of Continuous
Employment shall not be entitled to any portion of his Account under the Plan. A
Member who is not a Key Employee and whose employment is terminated after the
completion of two (2) or more Years of Continuous Employment shall be entitled
to receive the vested portion of his Account, determined in accordance with the
following schedule:

                                   5 or more              100%
</TABLE> 

The vesting schedule under this subsection (b)(3) shall apply to the portion of
the Account of a Member who is a non-Key Employee that represents contributions
made by the Company on the Member's behalf before or while the Plan is a
Top-Heavy Plan. In the event the Plan previously 

                                      -28-
<PAGE>
 
was a Top-Heavy Plan but subsequently is not a Top-Heavy Plan, the vesting
schedule under this subsection (b)(3) shall be changed to the vesting schedule
provided in Section 3.3 of the Plan; provided, however, that any non-Key
Employee who has completed at least three (3) or more Years of Continuous
Employment and who had at least one Hour of Service while the Plan was a Top-
Heavy Plan, shall be entitled to elect, within a reasonable period, which of the
above two vesting schedules is applicable to his Account.

               (4)  In the event that Congress should provide by statute, or the
Treasury Department should provide by regulation or ruling, that the limitations
provided in this Section 11.2 are no longer necessary for the Plan to meet the
requirements of Section 401 or other applicable law then in effect, such
limitations shall become void and shall no longer apply, without the necessity
of further amendment to the Plan.
