                                     PART I

Item 1.  Business

         Elcor Corporation (Registrant), incorporated in 1965 as a Delaware
corporation, is a publicly held corporation headquartered in Dallas, Texas.
Shares of the Registrant's common stock are traded on the New York Stock
Exchange with the ticker symbol - ELK.

Lines of Business

         Roofing Products

         The Registrant, through Elk Corporation of Dallas and its subsidiaries
(Elk), is engaged in the manufacture and sale of premium laminated fiberglass
asphalt residential roofing shingles and accessory products. Elk also
manufactures and sells nonwoven fiberglass roofing mats for use in manufacturing
asphalt roofing products, and nonwoven mats for use in other industrial
applications. Elk's premium laminated fiberglass asphalt shingle manufacturing
plants are located in Tuscaloosa, Alabama, Ennis, Texas, and Shafter,
California. The major products manufactured at Elk's roofing plants are premium
laminated fiberglass asphalt shingles sold under its brand names: Prestique(R)
Plus, Prestique(R) I, Prestique(R) II and Capstone(R). In fiscal 1995, Elk 
introduced Prestique premium laminated fiberglass asphalt shingle product lines
with the patented Enhanced High Definition(R) and Raised Profile(TM) look. In
addition, Elk also manufactures premium fiberglass asphalt hip and ridge
products: Seal-a-Ridge(R) and Z(R) ridge brands. Premium laminated asphalt
shingles account for approximately 30% of the residential sloped asphalt
shingle roofing market. About 80% of asphalt shingles are used in reroofing and
remodeling and 20% are used in new construction.
        
         Elk's roofing products are sold by employee sales personnel primarily
to roofing wholesale distributors, delivery being made by common carrier or by
customer vehicles from the manufacturing plants or warehouses. Elk's products
are distributed nationwide with Texas, California and Florida representing the
largest market areas. The Roofing Products segment accounted for approximately
86% of consolidated sales of the Registrant in fiscal 1998. For the past several
years, the building materials distribution industry has consolidated at a rapid
pace with many smaller independent distributors being acquired by emerging
larger national building products distributors. One customer, ABC Supply Co.
Inc., the largest roofing wholesale distributor in the United States, accounted
for 16% of consolidated sales in fiscal 1998, 14% of consolidated sales in
fiscal 1997, and 13% of consolidated sales in fiscal 1996.

         The company's new nonwoven fiberglass roofing mat facility at its
Ennis, Texas plant achieved its performance test level of operations effective
April 1, 1997. The new facility operates in parallel to the original fiberglass
mat manufacturing facility at the Ennis, Texas plant and produces nonwoven
fiberglass roofing mats and other mats for a variety of industrial uses. The new
plant was designed to more than triple Elk's previous manufacturing capacity for
nonwoven fiberglass mats.


                                       1

<PAGE>   3



         Elk's nonwoven fiberglass roofing mat facilities supply all of its
internal fiberglass roofing mat needs. In addition, roofing mats are sold by
employee sales personnel to other asphalt roofing products manufacturers.
Nonwoven mats are also sold to manufacturers of construction and industrial
products which use such mats in their products, and to distributors of
industrial filtration products. Elk's nonwoven mats are shipped by common
carrier to its other roofing plants and to its customers' locations.

         Industrial Products

         The Registrant, through Chromium Corporation (Chromium), is engaged in
two business lines. Chromium's Reciprocating Engine Components Division is
engaged in the remanufacture of diesel engine cylinder liners, including hard
chrome plating of cylinder bores and tin plating of pistons, primarily for the
railroad, marine, and stationary power industries; and hard chrome plating of
original equipment cylinder liners and tin plating of pistons for major domestic
locomotive manufacturers and stationary power equipment manufacturers.
Chromium's Conductive Coatings Division (CCD) is engaged in electroless
shielding of plastic enclosures for digital cellular phones, telecommunications
and other electronic equipment. Electroless shielding is designed to control the
level of electromagnetic and radio frequency interference (EMI/RFI) emissions
generated by electronic components. During fiscal 1998, CCD broadened its
product offerings to include dispense conductive gaskets which are formed in
place. Sales are generated by employee sales personnel, with delivery made
primarily by common carrier. To keep pace with rapidly growing demand, CCD
completed two expansions at its Lufkin, Texas facility in fiscal 1998, and a
third expansion is currently in progress. In fiscal 1999, CCD will be developing
plans for a second manufacturing location. In fiscal 1998, net sales for
Chromium Corporation were 11% of consolidated net sales.

         Another unit of the Registrant, OEL, LTD, d/b/a Ortloff Engineers, LTD
(Ortloff) is engaged in providing technology licensing and engineering support
services and in providing engineering consulting services to the oil and gas
production, gas processing and sulfur recovery industries. Ortloff licenses
technology covered by and related to ten patents owned by the Registrant for use
in new or redesigned natural gas and refinery gas processing facilities, and
utilizes technology licensed from others and its own expertise in the
performance of consulting and engineering assignments. Although one important
patent will expire in fiscal 1999, Ortloff continues to develop and patent
improved processes for natural gas processing. Moreover, Ortloff offers
significant expertise and other nonpatented technology associated with its
processes that is difficult for customers to obtain on a cost effective basis
from others. Three patents are currently pending and two new patent applications
are being written. These efforts reflect Ortloff's commitment to continually
update and advance its technological position. Ortloff was also successful in
expanding its markets into several parts of Latin America during fiscal 1998.

         Patent license fees are calculated by standard formulas that take into
account both specific project criteria and market conditions, adjusted for
special conditions that exist in a project. Engineering consulting assignments
are performed under consulting services agreements at negotiated rates.

Information as to Industry Segments

         For Financial Information by Company Segments, see the table on page 39
of this Annual Report on Form 10-K.

Accounting Change

         In fiscal 1998, the Registrant changed its method of accounting for
inventories from the LIFO method to the FIFO method. All prior period financial
information, including industry segment information, has been restated to
reflect this accounting change. See the Inventories footnote on page 28 of this
Annual Report of Form 10-K for additional information regarding this accounting
change.

Competitive Conditions

         Roofing Products

         Even though the asphalt roofing products manufacturing business is
highly competitive, the Registrant believes that Elk is a leading manufacturer
of premium laminated fiberglass asphalt shingles. Elk has been able to compete
successfully with its competitors, some of which are larger in size and have
greater financial resources.

         There are a number of major national and regional manufacturers
marketing their products in a portion or all of the market areas served by the
Registrant's plants. The Registrant competes primarily on the basis of product
quality, design and service. Typically, the Registrant is able to sell its
roofing products at higher prices than its competitors receive for similar type
products.

         Industrial Products

         The Registrant believes that Chromium is the leading remanufacturer of
diesel engine cylinder liners and pistons for the railroad and marine
transportation industries and is the primary supplier of hard chrome plated
finishes for original equipment diesel engine cylinder liners to all of the
major domestic locomotive manufacturers. The Registrant believes it has smaller
competitors in the locomotive diesel engine cylinder liner remanufacturing
market. The Registrant also believes that Chromium is one of the leading hard
chrome platers of recycled and original equipment large bore cylinder liners for
stationary power applications. Chromium has achieved a leading position in these
markets through competition on the basis of product performance, quality,
service and price. The Registrant, through the Conductive Coatings Division of
Chromium, is engaged in electroless shielding of plastic enclosures for digital
cellular phones, telecommunications, and other electronic equipment. The
Registrant believes the success of Chromium's Conductive Coatings Division in
becoming a qualified supplier for and obtaining significant orders from major
digital cellular phone manufacturers, together with telecommunications and other
electronic equipment manufacturers, has enabled it to become a market leader.


                                       3


<PAGE>   5



         The Registrant believes that it holds significant state-of-the-art
patents covering some of the most competitive processes for the cryogenic
processing of refinery and natural gas streams to remove the higher value
components, such as ethane and propane, which are primarily used as
petrochemical feedstocks. The Registrant believes that Ortloff has widely
recognized expertise in the design and operation of facilities for natural gas
and refinery gas processing and sulfur recovery.

Backlog

         Backlog was not significant, nor is it material, in the Registrant's
operations.

Raw Materials

         Roofing Products

         In the asphalt roofing products manufacturing business, the significant
raw materials are ceramic coated granules, asphalt, glass fibers, resins and
mineral filler. All of these materials are presently available from several
sources and are in adequate supply. Historically, the Registrant has been able
to pass some of the higher raw material and transportation costs through to the
customer.

         Industrial Products

         In the Registrant's business of hard chrome plating and remanufacturing
diesel engine cylinder liners and large bore cylinder liners, chromic acid is a
significant raw material which is presently available from a number of domestic
suppliers. The Registrant believes these domestic suppliers obtain the ore for
manufacturing chromic acid principally from sources outside the United States,
some of which may be subject to political uncertainty. The Registrant has been
advised by its suppliers that they maintain substantial inventories of chromic
acid in order to minimize the potential effects of foreign interruption in ore
supply. In the electroless shielding business, copper and nickel are the
significant raw materials. These materials are presently available and are in
adequate supply.

         No raw materials are utilized in the Registrant's engineering
consulting and technology licensing business.

Patents, Licenses, Franchises and Concessions

         The Registrant holds certain patents, particularly in its engineering
consulting and licensing business, which are significant to its operations.
However, the Registrant does not believe that the loss of any one of these
patents or of any license, franchise or concession would have a material adverse
effect on the Registrant's overall business operations. The Registrant, through
its subsidiary, Elk Corporation of Dallas, is involved in patent litigation
against GAF Building Materials Corporation and related GAF entities concerning
design and utility patents covering certain aspects of Elk's High Definition
shingles. Refer to Item 3 "Legal Proceedings" for a more detailed discussion of
this matter.



                                       4

Environmental Matters

         The Registrant and its subsidiaries are subject to federal, state and
local requirements regulating the discharge of materials into the environment,
the handling and disposal of solid and hazardous wastes, and protection of the
public health and the environment generally (collectively, Environmental Laws).
Certain facilities of the Registrant's subsidiaries ship waste products to
various waste management facilities for treatment or disposal. Governmental
authorities have the power to require compliance with these Environmental Laws,
and violators may be subject to civil or criminal penalties, injunctions or
both. Third parties may also have the right to sue for damages and/or to enforce
compliance and to require remediation of contamination.

         The Registrant and its subsidiaries are also subject to Environmental
Laws that impose liability for the costs of cleaning up contamination resulting
from past spills, disposal, and other releases of hazardous substances. In
particular, an entity may be subject to liability under the Federal
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or
Superfund) and similar state laws that impose liability -- without a showing of
fault, negligence, or regulatory violations -- for the generation,
transportation or disposal of hazardous substances that have caused or may
cause, environmental contamination. In addition, an entity could be liable for
cleanup of property it owns or operates even if it did not contribute to the
contamination of such property. From time to time, the Registrant or its
subsidiaries may incur such remediation and related costs at the company owned
plants and certain offsite locations.

         The Registrant anticipates that its subsidiaries will incur costs to
comply with Environmental Laws, including correcting existing non-compliance
with such laws and achieving compliance with anticipated future standards for
air emissions and reduction of waste streams. Such subsidiaries expend funds to
minimize the discharge of materials into the environment and to comply with
governmental regulations relating to the protection of the environment. Neither
these expenditures nor other activities initiated to comply with Environmental
Laws is expected to have a material impact on the consolidated financial
position, net earnings or liquidity of the Registrant.

Persons Employed

         At June 30, 1998, the Registrant and its subsidiaries had 867
employees.

Extended Payment Terms

         In some years, the Registrant's roofing products business grants
extended payment terms to certain customers for some product shipments during
the winter and early spring months, with payment generally due during the summer
months. As of June 30, 1998, $6,299,000 in receivables relating to such
shipments were outstanding, the majority of which are due in the first four
months of fiscal 1999. As of August 31, 1998, $3,647,000 of these receivables
have been collected.

Seasonal Business

         The Registrant's industrial products businesses are substantially
nonseasonal. The Registrant's roofing products manufacturing business is
seasonal to the extent that cold, wet or icy weather conditions during the late
fall and winter months in its marketing areas typically limit the 



                                       5

<PAGE>   7



installation of residential roofing products which causes sales to be slower
during such periods. Damage to roofs from extreme weather such as severe wind,
hurricanes and hail storms can result in higher demand for periods up to
eighteen months depending upon the extent of roof damage. Working capital
requirements and related borrowings fluctuate during the year because of
seasonality. Generally, working capital requirements and borrowings are higher
in the spring and summer months, and lower in the fall and winter months.

Item 2.  Properties

         All significant facilities are owned and unencumbered by liens in favor
of nonaffiliates except as discussed herein.

         Roofing Products

         Asphalt roofing products are manufactured at plants located at
Tuscaloosa, Alabama, Ennis, Texas and Shafter, California. Fiberglass roofing
mat, nonwoven industrial, reinforcement and filtration products are manufactured
on two production lines located at Ennis, Texas.

         Corporate headquarters and administrative offices for the asphalt
roofing products operations are located in the same leased facility as the
Registrant's corporate offices in Dallas, Texas.

         Industrial Products

         Plants for the hard chrome plating of original equipment and
remanufactured diesel engine cylinder liners and related equipment are located
in Cleveland, Ohio and Lufkin, Texas. The Conductive Coatings Division's (CCD)
EMI/RFI shielding facility is located at the Lufkin, Texas plant. During fiscal
1998, CCD completed two expansions and a third expansion is currently in
progress.

         Corporate headquarters and administrative offices are located in the
same leased facility as the Registrant's corporate offices in Dallas, Texas.

         The Ortloff engineering and process licensing group is located in
leased offices in Midland, Texas.

         Corporate Offices

         The Registrant's corporate headquarters is located in leased offices in
Dallas, Texas.

         In addition, one of the Registrant's subsidiaries owns land and
buildings in Waco, Texas, formerly used in the discontinued solid waste handling
equipment manufacturing business. This facility is currently subject to a
lease/purchase agreement.

Item 3.  Legal Proceedings

         GAF Patent Litigation

         On February 8, 1994, a wholly owned subsidiary, Elk Corporation of
Dallas (Elk) was granted a design patent covering the ornamental aspects of
certain Elk shingles. On December 6, 1994, Elk was granted a utility patent on
the functional aspects of certain Elk shingles. Elk has sued GAF Building
Materials Corporation and related GAF entities (collectively GAF) in federal
court for infringement of these patents and trade dress. In the design patent
case, Elk seeks to recover as damages the total profit that GAF has made from
the infringing shingles. In the utility patent case, Elk seeks to recover as
damages a reasonable royalty on GAF's sales of infringing shingles and certain
lost profits.

         GAF seeks a declaratory judgment that the Elk patents are not infringed
and are either invalid or unenforceable. GAF has also asserted claims for unfair
competition, Lanham Act violations based on alleged false advertising, and
common law fraud, generally praying for damages of not less than $25 million
including actual and punitive damages, plus interest, costs, and reasonable
attorney fees. Elk disputes GAF's claims, and management intends vigorously to
defend them and to enforce its intellectual property rights. In April, 1998, the
District Court for the Northern District of Texas entered a partial final
judgment against Elk in the design patent case based on an inequitable conduct
ruling and certified the case for appeal. Elk has contested that judgment in an
appeal which it has filed with the United States Court of Appeals for the
Federal Circuit. Elk expects its appeal to be decided by the Court of Appeals in
1999. In the interim, trial on the trade dress claim and certain other matters
in the design patent case and trial in the utility patent cases are unscheduled
but pending.

         While management can give no assurances regarding the ultimate outcome
of the litigation, outside counsel believe that Elk will prevail on its patent
and trade dress claims and that Elk will defeat GAF's counterclaims. Even if the
outcome were to be adverse to Elk, it is not expected to have a material effect
on the Registrant's financial position or liquidity.

         Gibraltar Tort Litigation

         In December 1995 through August 1996, Chromium Corporation was sued in
four separate tort lawsuits brought by the same attorneys on behalf of
plaintiffs who allege unspecified personal injuries and property damages
associated with the former operation of a licensed hazardous waste treatment,
storage and disposal facility in Smith County, Texas known as the Gibraltar
facility. The four suits were brought against or expanded to include the current
and former owners and operators of the facility, and more than fifty other
defendants, including Chromium and several Fortune 500 companies, as generators
of waste sent to the facility (as named in a particular lawsuit,"Generator
Defendants").

         The plaintiffs have non-suited or dismissed the Generator Defendants
from two of the cases. In another case, Williams, et al. v. Akzo Nobel
Chemicals, Inc., et al., the Smith County (Texas) District Court has dismissed
Chromium and certain other Generator Defendants. Plaintiffs' appeal of this
decision is pending.



                                       7
<PAGE>   9


         Chromium remains a defendant in the fourth case, Adams v. American
Ecology Environmental Services Corporation, pending in Tarrant County (Texas)
District Court since August 1996, when approximately 650 plaintiffs filed it. On
July 30, 1998, the court issued a ruling denying the Generator Defendants'
motions for a discovery management order and lifted the stay on discovery in the
case. Discovery has recommenced and is ongoing. No trial date has been set for
Adams as yet.

         In connection with these cases, Chromium has entered into joint defense
agreements with more than twenty other Generator Defendants. Chromium also has
demanded a defense and indemnity from the facility owners pursuant to the waste
disposal contract and from Chromium's insurers. To date, the facility owners
have not responded and the insurers have declined or failed to accept the
defense and indemnity obligation. Chromium intends to pursue its defenses
vigorously.

         Management believes that the claims brought against Chromium in these
cases are without merit. While management can give no assurances regarding the
ultimate outcome of this litigation, it believes that it will not have a
material adverse effect on the consolidated results of operations, financial
position or liquidity of the Registrant.

         Chromium/TWC Settlement

         In May 1993, Chromium entered into an Agreed Order with the Texas Water
Commission (TWC) in settlement of an enforcement proceeding. Pursuant to the
Agreed Order, the TWC assessed $60,000 in penalties and agreed to defer and
forgive $74,800 in penalties contingent on Chromium's completion of certain
technical and remedial activities at the Lufkin facility ("Technical
Recommendations"). Chromium has paid the assessed penalties, and completed the
Technical Recommendations. On August 31, 1998, the Texas Natural Resource
Conservation Commission, TWC's successor, issued a letter stating that it
considered all of the actions required under the Agreed Order to have been
fulfilled and completed.

         Frontier Chemical Site

         In May 1993, Chromium received a Notification Letter from the United
States Environmental Protection Agency (USEPA) informing Chromium that USEPA had
reason to believe that Chromium was a Potentially Responsible Party (PRP) under
the Comprehensive Environmental Response, Compensation and Liability Act at the
Frontier Chemical Royal Avenue Site (Site), a former state-permitted waste
processing and management facility in Niagara Falls, New York. In September
1993, Chromium entered into an Administrative Order on Consent with USEPA under
which Chromium and other PRPs agreed to perform Phase I response activities at
the Site and to reimburse USEPA for response costs incurred by USEPA at the
Site.



                                       8
<PAGE>   10


         All of the Phase I work was concluded in May 1994. Chromium was
assessed a total of $109,250 of the $4 million cost estimate assessed to all
Phase I PRPs. Chromium has not been and does not expect to be named as a PRP in
Phase II or any subsequent phases of cleanup.

         Certain Phase I and Phase II PRPs intervened in a suit brought by the
New York Attorney General seeking recovery of approximately $1.2 million in
proceeds from a closure bond relating to the Site. If such intervention is
successful, participating Phase I and Phase II PRPs will share in any recovery
with the State of New York. In February 1998, a court denied the motion for
summary judgment of the PRPs, including Chromium, in the suit, and granted the
New York Attorney General's opposing motion. Appeal from the ruling is pending.

         In March 1997, the USEPA issued its demand for future costs pursuant to
the Administrative Order on Consent. The PRPs have objected to this cost demand
and have demanded an accounting. Resolution of this dispute still is pending,
but even if the USEPA demand remains at the current amount, no further
assessments from Chromium will be necessary to meet it; moreover, Chromium
received a refund of a small portion of its original assessment on the basis of
the existing demand.

         Chromium's final assessment in this matter net of all recoveries cannot
be calculated until its PRP group determines which assessments are
uncollectible, and the closure bond action and USEPA cost reimbursement are
resolved. Management of the Registrant believes that the final disposition of
this matter will not have a material adverse effect on the consolidated results
of operations, financial position, or liquidity of the Registrant.

         Other

         There are various other lawsuits and claims pending against the
Registrant and its subsidiaries arising in the ordinary course of their
businesses. In the opinion of the Registrant's management based in part on
advice of counsel, none of these actions should have a material adverse effect
on the Registrant's consolidated results of operations, financial position, or
liquidity.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations.

RESULTS OF OPERATIONS

FISCAL 1998 COMPARED TO FISCAL 1997

         During the fiscal year ended June 30, 1998, sales increased 16% to
$268,178,000 from the $230,756,000 reported in fiscal 1997. Net income in fiscal
1998 increased 49% to $18,324,000 from $12,276,000 in the prior fiscal year.
Both the Roofing Products and Industrial Products Groups generated significant
increases in sales. The Roofing Products Group reported better operating results
in fiscal 1998 as compared to the prior fiscal year. However, the substantial
increase in net income was primarily attributable to increased demand and
dramatically improved operating results in each of the Industrial Products
Group's principal operations of: (1) conductive coatings used in digital
cellular phones and in other electronic equipment; (2) remanufactured diesel
engine components used in the transportation industry; and (3) technology
licensing and consulting services for the natural gas processing industry. In
fiscal 1998, the company changed its method of accounting for inventories from
the last-in, first-out (LIFO) method to the first-in, first-out (FIFO) method.
Accordingly, fiscal 1997 amounts have been restated to reflect the accounting
change. Had the company not made this change, net income would have been lower
by $130,000 in fiscal 1998.

         Sales for the Roofing Products Group increased 11% in fiscal 1998 to
$229,475,000 from $207,017,000 in fiscal 1997. The Western United States
produced very strong demand for Elk Prestique premium laminated shingles.
However, shipments on the West Coast were limited during much of the second half
of fiscal 1998 by El Nino's impact, as many roofing contractors could not
replace leaking roofs during extended periods of heavy rainfall. Demand was also
higher in the Southeast, Midwest and North regions. Only in the Southwestern
region was demand lower than in the previous fiscal year. Average selling prices
were about the same in fiscal 1998 compared to fiscal 1997.

         Elk's roofing mat operations achieved significantly higher sales and
operating profit, primarily as a result of growing demand for its high quality
roofing mats and specialty industrial products.

         Operating income for the Roofing Products Group increased 18% in fiscal
1998 to $24,885,000 from $21,052,000 in fiscal 1997. Each of Elk's three roofing
plants and its roofing mat operation were very profitable in fiscal 1998,
although the Ennis, Texas roofing plant's operating results were lower in fiscal
1998 as a result of lower demand in the Southwestern region. The impact of high
winds and heavy rainfall in much of the nation this past winter has increased
the level of demand during the latter months of fiscal 1998 and early fiscal
1999. The company currently anticipates sharply higher demand for its premium
laminated fiberglass asphalt shingles and mat products in fiscal 1999.

         Sales for the Industrial Products Group increased 64% in fiscal 1998 to
$38,586,000 from $23,542,000 in fiscal 1997. Operating income for this Group
increased to $10,780,000 in fiscal 1998 from $3,498,000 in fiscal 1997. Each of
the three principal operations in this business segment reported significantly
higher sales and operating income in fiscal 1998. Chromium Corporation continued
to benefit from strong demand for its Compushield(R) conductive coatings and
dispense



                                       14
<PAGE>   16


conductive gasketing used in digital cellular phones and in other electronic
equipment. Chromium also experienced higher sales and significantly improved
margins in plating certain proprietary finishes for large diesel engine
components during fiscal 1998. Further, Ortloff Engineers' revenues from its
technology licensing and consulting services for the natural gas processing
industry about doubled in fiscal 1998 as compared to fiscal 1997. This resulted
in a tripling of operating income for this business activity in fiscal 1998.
However, management expects that Ortloff Engineers' sales and operating profit
will decline in fiscal 1999 as a result of lower oil prices, which may cause
some potential customers to defer planned projects until economic conditions are
more favorable.

         Selling, general and administrative (SG&A) costs in fiscal 1998
increased 12.9% from fiscal 1997 primarily as a result of increased business
activity. As a percentage of sales, SG&A costs declined to 13.0% of sales in
fiscal 1998 from 13.4% of sales in fiscal 1997.

         Interest expense in fiscal 1998 was $2,577,000 compared to $1,136,000
in fiscal 1997. In fiscal 1997, $1,784,000 of interest was capitalized in
connection with the company's major facilities expansion program. In fiscal
1998, the company capitalized $160,000 in interest costs in connection with its
existing plant expansion program.

FISCAL 1997 COMPARED TO FISCAL 1996

         During the fiscal year ended June 30, 1997, sales grew to $230,756,000,
a 17% increase over fiscal 1996 sales of $196,462,000. Both the Roofing Products
and Industrial Products Groups contributed to the increase in sales. Net income
in fiscal 1997 increased 15% to $12,276,000 from the $10,676,000 achieved in
fiscal 1996. Higher net income was primarily attributable to the Industrial
Products Group, which achieved substantially improved operating results in
fiscal 1997. In addition, in fiscal 1996 the Company incurred $1,595,000 in
pretax charges in connection with a provision for the adoption of SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of" and the reduction in value of certain other assets during that
fiscal year. Fiscal 1997 and 1996 amounts have been restated to reflect the
accounting change for inventories adopted in fiscal 1998.

         Sales for the Roofing Products Group increased 16% in fiscal 1997 to
$207,017,000 from $178,378,000 in fiscal 1996. The Roofing Products Group
accounted for 90% of consolidated sales in fiscal 1997 and 91% in fiscal 1996.
Higher sales were primarily due to an increase in shipments of premium laminated
fiberglass asphalt shingles. Sales from the new plant in Shafter, California
accounted for a significant part of the increased shipments. Average selling
prices were about the same in fiscal 1997 compared to fiscal 1996.

         Operating profit for the Roofing Products Group decreased to
$21,052,000 in fiscal 1997 from $22,675,000 in fiscal 1996. The Shafter,
California plant achieved profitable operations in fiscal 1997 after incurring a
significant operating loss in the prior fiscal year. Although both of the other
roofing plants were very profitable, operating income at these facilities was
lower in fiscal 1997, primarily as a result of higher freight rates, higher raw
materials costs and costs of implementing a fourth shift operation at the
Tuscaloosa, Alabama roofing plant to increase that facility's production
capacity.

         The company's new nonwoven fiberglass roofing mat plant at its Ennis,
Texas facility achieved its performance test level of operations effective
April 1, 1997. Although overall mat plant operations were profitable in fiscal
1997, operating income from mat plant operations was significantly lower in
fiscal 1997 compared to fiscal 1996 due primarily to higher costs associated
with the new plant in its start-up year of operations.

         Sales for the Industrial Products Group increased 31% in fiscal 1997 to
$23,542,000 from $17,930,000 in fiscal 1996. Operating income for this business
segment increased to $3,498,000 in fiscal 1997 compared to an operating loss of
$224,000 in fiscal 1996. Chromium Corporation achieved significantly higher
revenues and operating results relating to conductive coatings of plastic
enclosures for electronic equipment. Improved operating conditions in this area
more than offset decreased demand for Chromium's hard chrome plated diesel
engine cylinder liners for the railroad, marine and stationary power industries.
In addition, in fiscal 1996, Chromium recorded $1,037,000 in charges relating to
a reduction in value of assets at its Cleveland, Ohio plant upon the adoption of
SFAS No. 121. Ortloff Engineers achieved much higher revenues in fiscal 1997
from licensing the company's process technology for construction of both new
natural gas processing plants and retrofits to upgrade existing gas processing
plants.

         Selling, general and administrative costs as a percentage of sales were
13.4% for fiscal 1997 compared to 14.8% in fiscal 1996. In fiscal 1995, the
company established a larger sales organization to better serve growing market
areas. During fiscal 1997, this larger organization was able to service the
increase in sales orders without a proportionate increase in overall selling
costs.

         Interest expense was higher in fiscal 1997 as a result of the company's
completion of its three-year major facilities expansion program which was
completed in March 1997. Subsequent to that date, all interest was expensed as
incurred.

LIQUIDITY AND CAPITAL RESOURCES

         The company generated cash flows from operating activities of
$23,207,000 in fiscal 1998, despite a $10,115,000 increase in working capital.
The increase in working capital was primarily the result of higher trade
receivables, which increased $13,272,000 during fiscal 1998. Receivables
increased primarily as a result of higher sales in fiscal 1998, together with a
higher level of deferred payment term receivables. At June 30, 1998, deferred
payment term receivables from promotional programs to certain customers were
$6,299,000 compared to $2,139,000 at June 30, 1997. Deferred receivables
outstanding at June 30, 1998, are primarily due during the first four months of
fiscal 1999. The increase in receivables was partially offset by lower
inventories and prepaid expenses. The current ratio at June 30, 1998 was 3.5 to
1 compared to 3.0 to 1 at June 30, 1997. Historically, working capital
requirements and associated borrowings fluctuate during the year because of
seasonality in some market areas. Generally, working capital requirements and
borrowings are higher in the spring and summer, and lower in the fall and
winter.

         The company used $12,614,000 for investing activities in fiscal 1998.
The majority of investing expenditures were for additions to property, plant and
equipment. Most capital expenditures in fiscal 1998 were for productivity,
capacity, and cost improvement projects at the current roofing plants and for
the development of new computer systems. In addition, the company expanded its
capacity in the Chromium Corporation Conductive Coatings operation to meet
rapidly growing demand for its Compushield process. Capital expenditures are
expected to be about $24,000,000 in fiscal 1999. The majority of currently
planned fiscal 1999 capital expenditures are a continuation of productivity,
capacity and cost improvement projects at its existing roofing plants, continued
capacity expansion of the Conductive Coatings operation, and capital costs
associated with developing new computer systems. The company expects to invest
about $100 million over the next three years to expand capacity and improve
productivity at existing plants and to build new plants in both the Roofing
Products and Industrial Products segments.

         Cash flows used for financing activities were $8,954,000 in fiscal
1998, primarily resulting from dividend payments, a $4,600,000 decrease in
long-term debt, and purchases of treasury shares. Long-term debt represented 28%
of the $173,956,000 of invested capital (long-term debt plus shareholders'
equity) at June 30, 1998. In December 1997, the company increased its unsecured
revolving line of credit to $100,000,000 and extended the term to December 15,
2002. As of June 30, 1998, $50,210,000 was available under this facility.

         The company's Board of Directors has authorized the purchase of up to
$10,000,000 of the company's common shares on the open market to be used for
general corporate purposes. As of June 30, 1998, 327,850 shares with cumulative
cost of $5,466,000 had been repurchased. In September 1997, the Board of
Directors increased the regular quarterly cash dividend to six cents per common
share (after giving effect to a stock split) and declared a three-for-two stock
split payable in the form of a stock dividend distributed on November 12, 1997
to shareholders of record on October 16, 1997.

         Management believes that current cash and cash equivalents, cash flows
from operations and its unsecured revolving credit facility should be sufficient
during fiscal 1999 and beyond to fund its planned capital expenditures, working
capital needs, dividends, stock repurchases and other cash requirements.
However, management believes it could secure additional capital at favorable
rates, if needed, to support its capital expansion program.

NEW ACCOUNTING STANDARDS

         In June 1997, the Financial Accounting Standards Board (FASB) issued
SFAS No. 130, "Reporting Comprehensive Income," which establishes standards of
reporting of comprehensive income and its components in the consolidated
financial statements. The company will adopt SFAS No. 130 in fiscal 1999, but
does not expect the adoption of SFAS No. 130 to impact the company's financial
position or results of operations.

         In June 1997, the FASB also issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." SFAS No. 131 requires public
companies to disclose, among other things, certain interim and annual financial
information about the enterprise using a new management approach. This approach
requires segment information to be reported based on how management evaluates
the operating performance of its business units or segments. The company 



                                       17

<PAGE>   19

will adopt SFAS No. 131 in fiscal 1999 and does not currently anticipate
significant changes in its reportable segments.

         In April 1998, the Accounting Standards Executive Committee (AcSec) of
the American Institute of Certified Public Accountants issued Statement of
Position 98-5, "Reporting on the Costs of Start-Up Activities," requiring, among
other things, companies to expense on a current basis previously capitalized
start-up costs. At June 30, 1998, the company had $6,682,000 of unamortized
capitalized start-up costs. This Statement of Position is effective for
financial statements for fiscal years beginning after December 15, 1998, unless
adopted earlier. The company plans to adopt this new accounting standard in
fiscal 1999 at which time all remaining unamortized capitalized start-up costs
will be expensed and reflected in the Consolidated Statement of Operations as a
cumulative change in accounting principle.

YEAR 2000 ISSUE

         The company is currently developing a new information system for its
critical financial, distribution and manufacturing applications. The system is
scheduled for completion and full implementation in the summer of 1999 at an
estimated total cost of about $10 million. While the primary purpose of this new
information system is to modernize and improve the company's operations, it is
also expected to resolve the Year 2000 issues in these critical computer
systems. Costs to develop this new information system are being capitalized in
accordance with SOP 98-1. Costs to implement the new information system and
other costs relating to Year 2000 readiness are being expensed as incurred. As
of June 30, 1998, the company's expenditures for its new information system have
been $3.7 million and its expenditures for Year 2000 readiness projects have
been less than $200,000. At this time, other than the cost of developing and
implementing its new information system, the company does not believe that the
costs of addressing the Year 2000 issue will be material. The company does not
believe that other critical information systems work has been deferred due to
its Year 2000 efforts.

         The company also has teams of employees and consultants who are
reviewing other computer applications and systems not included in the scope of
the new information system, including systems other than information systems
that have embedded technology, and its interaction with its suppliers, customers
and other business partners for Year 2000 readiness. The company is close to
completing the process of taking relevant inventory, assessing risk, assigning
priorities to various tasks and performing limited internal tests. The company
has completed its initial remedial programming for its mainframe computer system
and is ready to begin testing this system. The company has developed contingency
plans for its critical information system which primarily consist of making its
existing information system Year 2000 compliant in the event the new system is
not completed by its scheduled date. Contingency plans for other aspects of Year
2000 readiness are currently being developed. The company expects to have fully
developed action and contingency plans by the end of calendar 1998, and to have
completed integrated testing and any remediation before January 1, 2000.

         The company believes the Year 2000 readiness project is on schedule for
timely completion. Based on a current assessment of risks relating to its Year
2000 readiness, the company does not believe that this issue will result in
uncertainty that is reasonably likely to materially affect future financial
results or operating performance.

FORWARD - LOOKING STATEMENTS

         In an effort to give investors a well-rounded view of the company's
current condition and future opportunities, management's discussion and analysis
of the results of operations and financial condition and other sections of this
Form 10-K contain "forward-looking statements" about its prospects for the
future. Such statements are subject to certain risks and uncertainties which
could cause actual results to differ materially from those projected. Such risks
and uncertainties include, but are not limited to the following:

         1.       The company's roofing products business is cyclical and is
                  affected by weather and some of the same economic factors that
                  affect the housing and home improvement industries generally,
                  including interest rates, the availability of financing and
                  general economic conditions. In addition, the asphalt roofing
                  products manufacturing business is highly competitive. Actions
                  of competitors, including changes in pricing, or slowing
                  demand for asphalt roofing products due to general or industry
                  economic conditions or the amount of inclement weather could
                  result in decreased demand for the company's products, lower
                  prices received or reduced utilization of plant facilities.
                  Further, changes in building codes and other standards from
                  time to time can cause changes in demand, or increases in
                  costs that may not be passed through to customers.

         2.       In the asphalt roofing products business, the significant raw
                  materials are ceramic coated granules, asphalt, glass fibers,
                  resins and mineral filler. Increased costs of raw materials
                  can result in reduced margins, as can higher trucking and rail
                  costs. Historically, the company has been able to pass some of
                  the higher raw material and transportation costs through to
                  the customer. Should the company be unable to recover higher
                  raw material and transportation costs from price increases of
                  its products, operating results could be lower than projected.

         3.       During fiscal 1997, the company completed the construction of
                  a plant at the company's Ennis, Texas facility to manufacture
                  nonwoven fiberglass roofing mats and other mats for a variety
                  of industrial uses. The company also expects to make up to
                  $100 million in new investments to expand capacity and improve
                  productivity at existing plants and to build new plants over
                  the next three years. Progress in achieving anticipated
                  operating efficiencies and financial results is difficult to
                  predict for new plant facilities. If such progress is slower
                  than anticipated, if substantial cost overruns occur in
                  building new plants, or if demand for products produced at new
                  plants does not meet current expectations, operating results
                  could be adversely affected.

         4.       Certain facilities of the company's industrial products
                  subsidiaries must utilize hazardous materials in their
                  production process. As a result, the company could incur costs
                  for remediation activities at its facilities or off-site, and
                  other related exposures from time to time in excess of
                  established reserves for such activities.


                                       19
<PAGE>   21


         5.       The company's litigation, including its patent infringement
                  suits against GAF Building Materials Corporation and certain
                  affiliates, is subject to inherent and case-specific
                  uncertainty. The outcome of such litigation depends on
                  numerous interrelated factors, many of which cannot be
                  predicted.

         6.       Even with fully developed action and contingency plans for
                  Year 2000 readiness, it is possible that the company will not
                  achieve full internal readiness. Further, the company's
                  business may be adversely affected by external Year 2000
                  disruption that the company is not in position to control,
                  including but not limited to potential disruptions in power
                  and other energy supplies, telecommunications or other
                  infrastructure, potential disruptions in transportation and
                  the supply of raw materials, and potential disruptions in
                  financial and banking systems. Year 2000 problems therefore
                  could result in unanticipated expenses or liabilities,
                  production or disruption delays or other adverse effects on
                  the company.

         7.       Although the company currently anticipates that most of its
                  needs for new capital in the near future will be met with
                  internally generated funds, significant increases in interest
                  rates could substantially affect its borrowing costs under its
                  existing loan facility, or its cost of alternative sources of
                  capital.

         8.       Each of the company's businesses, especially its Conductive
                  Coatings Division's business, is subject to the risks of
                  technological changes that could affect the demand for or the
                  relative cost of the company's products and services, or the
                  method and profitability of the method of distribution or
                  delivery of such products and services. In addition, the
                  company's businesses each could suffer significant setbacks in
                  revenues and operating income if it lost one or more of its
                  largest customers.

         9.       Although the company insures itself against physical loss to
                  its manufacturing facilities, including business interruption
                  losses, natural or other disasters and accidents, including
                  but not limited to fire, earthquake, damaging winds and
                  explosions, operating results could be adversely affected if
                  any of its manufacturing facilities became inoperable for an
                  extended period of time due to such events.

         Parties are cautioned not to rely on any such forward-looking beliefs
or judgments in making investment decisions.

INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Directors,
Elcor Corporation

         We have audited the accompanying consolidated balance sheets of Elcor
Corporation (a Delaware corporation) and subsidiaries as of June 30, 1998 and
1997, and the related consolidated statements of operations, cash flows and
shareholders' equity for each of the three years in the period ended June 30,
1998. These financial statements are the responsibility of the company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Elcor
Corporation and subsidiaries as of June 30, 1998 and 1997, and the results of
their operations and their cash flows for each of the three years in the period
ended June 30, 1998, in conformity with generally accepted accounting
principles.

         As discussed in the Summary of Significant Accounting Policies, the
company has given retroactive effect to the change in the method of accounting
for inventories from the last-in, first-out method to the first-in, first-out
method in fiscal 1998.

         As discussed in the Summary of Significant Accounting Policies, the
company adopted Statement of Financial Accounting Standards No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of," in fiscal 1996.

     The Summary of Significant Accounting Policies and Notes to Consolidated
     Financial Statements are an integral part of this statement.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BUSINESS

         Elcor Corporation (the company), through subsidiaries, is engaged in
two lines of business: Roofing Products and Industrial Products. The Roofing
Products segment, which accounts for 86% of consolidated sales, manufactures and
sells premium laminated fiberglass asphalt residential roofing products,
together with nonwoven mats used in manufacturing asphalt roofing products and
various industrial applications. The Industrial Products group of companies is
engaged in the shielding of plastic enclosures used in digital cellular phones
and in other industries from electromagnetic and radio frequency interference,
the plating of proprietary finishes for large diesel engine cylinder liners and
pistons, and engineering consulting services and licensing of certain patented
technologies.

PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of the
company and all subsidiaries after elimination of significant intercompany
balances and transactions. Service revenues and related expenses are not
disaggregated in the Consolidated Statement of Operations due to immateriality.
Certain prior year information has been restated as a result of a change in
accounting for inventories as discussed in the Inventories section, and the
three-for-two stock split in November 1997.

USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

CONCENTRATION OF CREDIT RISK

         The majority of the company's sales are in the Roofing Products segment
and its primary customers are building materials distributors. For the past
several years, the building materials distribution industry has consolidated at
a rapid pace with many smaller independent distributors being acquired by
emerging larger national building products distributors. One customer accounted
for 16%, 14% and 13% of consolidated sales in fiscal years 1998, 1997 and 1996,
respectively. The company performs ongoing credit evaluations and maintains
reserves for potential credit losses.

REVENUE RECOGNITION

         Revenue is recognized at the time products are shipped to the customer
or at the time services are rendered.

INVENTORIES

         Inventories are stated at the lower of cost (including direct
materials, labor, and applicable overhead) or market, using the first-in,
first-out (FIFO) method. Inventories were comprised of:

</TABLE>

         In fiscal 1998, the company changed its method of accounting for
inventories from the LIFO method to the FIFO method. Management believes that as
a result of productivity improvements and the declining cost of raw materials
since the adoption of the LIFO method in fiscal 1985, the FIFO method provides a
better measurement of operating results.

         In accordance with Accounting Principles Board Opinion No. 20,
"Accounting Changes," prior period financial statements have been restated to
reflect this accounting change.

         The effect on net income by year of this accounting change is
summarized as follows (in thousands, except per share amounts):

           Further, as of July 1, 1993, inventories were reduced $905,000,
    deferred taxes reduced $314,000 and retained earnings reduced $591,000 to
    reflect this accounting change on reported beginning balances.

PROPERTY, PLANT AND EQUIPMENT

         Property, plant and equipment are stated at cost. Major renewals and
improvements are capitalized, while maintenance and repairs are expensed when
incurred. Depreciation is computed over the estimated useful lives of
depreciable assets using the straight-line method. Useful lives for property and
equipment are as follows:

<TABLE>
         <S>                                <C>     
         Buildings and improvements         10 - 40 years
         Machinery and equipment             5 - 20 years
         Computer equipment                  3 -  6 years
         Office furniture and equipment      5 - 12 years
</TABLE>

         The cost and accumulated depreciation for property, plant and equipment
sold, retired, or otherwise disposed of are relieved from the accounts, and
resulting gains or losses are reflected in income. Historically, preoperating
and start-up costs incurred in connection with the construction of major new
manufacturing facilities were capitalized until such facilities became
operational. These costs were then amortized over a five-year period.
Capitalized preoperating and start-up costs included in capital expenditures
were $977,000 and $4,772,000 in fiscal years 1997 and 1996 respectively.
Effective in fiscal 1999, preoperating and start-up costs will be expensed as
incurred in accordance with AcSec Statement of Position 98-5, as described more
fully in the New Accounting Standards section of these financial statements.
Interest is capitalized in connection with the construction of major facilities.
The capitalized interest is recorded as part of the asset to which it relates
and is amortized over the asset's estimated useful life. In 1998, 1997 and 1996,
$160,000, $1,784,000 and $1,459,000 of interest cost was capitalized,
respectively.

INCOME TAXES

         Deferred income taxes are provided to reflect temporary differences
between the financial reporting basis and the tax basis of the company's assets
and liabilities using presently enacted tax rates.

IMPAIRMENT OF LONG-LIVED ASSETS

         During the fourth quarter of fiscal 1996, the company adopted Statement
of Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed Of." The company
recorded a provision of $1,037,000 to reduce the assets of Chromium
Corporation's Cleveland plant and provide for related environmental remediation
in the Industrial Products segment relating to the new accounting standard. The
company had previously reduced the value of certain equipment in the Roofing
Products segment by $558,000.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

EARNINGS PER SHARE

         In accordance with SFAS No. 128, "Earnings Per Share," basic earnings
per share were computed by dividing net income by the weighted average number of
shares of common stock outstanding during the year, adjusted for the
three-for-two stock split in November 1997. The reconciliation of basic earnings
per share to diluted earnings per share is shown in the following table.

LONG-TERM DEBT

         Effective December 15, 1997, the company increased its unsecured
revolving credit facility (Facility) to $100,000,000 of primary credit,
including up to a maximum of $5,000,000 in letters of credit, through December
15, 2002. At June 30, 1998, letters of credit totaling $1,790,000 were
outstanding.

         Borrowings under the Facility bear interest at (1) the higher of the
federal funds rate plus .5% or the lender's prime rate, or (2) at the company's
option, LIBOR, in each case plus specified basis points based on the ratio of
the company's total indebtedness to total capital. The Facility also provides
for a commitment fee on the average unused portion of the line and is also based
on the ratio of the company's total indebtedness to total capital. Based on
financial ratios at June 30, 1998, the LIBOR borrowing rate was LIBOR plus .5%
and the commitment fee was .175% of the average unused portion of the line. The
average interest rate paid on indebtedness in fiscal 1998 was 6.4%.

<PAGE>   32


         The loan agreement, among other things, limits the sale or pledging of
assets of subsidiaries involved in manufacturing asphalt roofing products, and
requires maintenance of specified current ratios, capitalization ratios and cash
flow levels. Dividend payments and stock repurchases are limited to certain
specified levels providing no default or event of default would occur. At June
30, 1998, total cumulative dividend payments and stock repurchased since July 1,
1993 were subject to a $32,765,000 limitation. Actual expenditures for these
items as of June 30, 1998 have been $13,204,000.

SHAREHOLDERS' EQUITY

         Authorized common stock, par value $1.00, is 50,000,000 shares, of
which 13,325,569 shares were issued at June 30, 1998 and 13,221,119 shares were
issued at June 30, 1997. The Board of Directors is authorized to issue up to
1,000,000 shares of preferred stock, without par value, in one or more series
and to determine the rights, preferences, and restrictions applicable to each
series. No preferred stock has been issued.

         In September 1997, the Board of Directors declared a three-for-two
stock split payable in the form of a stock dividend which was distributed on
November 12, 1997. An amount equal to the par value of the common shares issued
in connection with the split was transferred from paid-in capital to the common
stock account. Appropriate references to number of shares and to per share
information in the Consolidated Financial Statements have been adjusted to
reflect the stock split on a retroactive basis.

SHAREHOLDER RIGHTS PLAN

         On May 26, 1998, the company's Board of Directors adopted a new
Shareholder Rights Plan which took effect when the existing rights plan expired
on July 8, 1998. Under the new plan, rights were constructively distributed as a
dividend at the rate of one right for each share of common stock of the company
held by the shareholders of record as of the close of business on July 8, 1998.
Until the occurrence of certain events, the rights are represented by and traded
in tandem with common stock. Each right will separate and entitle shareholders
to buy stock upon an occurrence of certain takeover or stock accumulation
events. Should any person or group (Related Person) acquire beneficial ownership
of 15% or more of the company's common stock other than certain bona fide
institutional investors to whom a 20% threshold applies, all rights not held by
the Related Person become rights to purchase one one-hundredth of a share of
preferred stock for $165 or $165 of Elcor common stock at a 50% discount. If
after such an event the company merges, consolidates or engages in a similar
transaction in which it does not survive, each holder has a "flip over" right to
buy discounted stock in a surviving entity.

         Under certain circumstances, the rights are redeemable at a price of
$0.01 per right. Further, upon defined stock accumulation events, the Board of
Directors has the option to exchange one share of common stock per right. The
rights will expire by their terms on July 8, 2008.

         At June 30, 1998, 1997 and 1996, 209,813, 218,231 and 173,694 shares
were exercisable, respectively. A total of 250,064, 397,271 and 547,274 shares
were reserved for future grants at June 30, 1998, 1997 and 1996, respectively.

         Beginning in fiscal 1997, the company adopted the disclosure-only
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation."
Accordingly, no compensation cost has been recognized with respect to the
company's stock option plan. Pro forma information regarding net income and
income per share set forth below has been determined as if the company had
accounted for its stock options under the fair value methodology prescribed by
SFAS No. 123. The fair value of each option grant is estimated on the date of
grant using the Black-Scholes option-pricing model

with the following weighted-average assumptions for fiscal 1998, 1997 and 1996;
dividend yields of 1.1%, 1.5% and 1.1%; risk-free interest rates of 6.2%, 6.5%
and 6.2%; expected market price volatility of .413, .429 and .450; and expected
lives of options of 8.5, 6.9 and 7.5 years. Based on this model, the weighted
average fair value of stock options granted in fiscal 1998, 1997 and 1996 was
$11.63, $5.78 and $7.48, respectively.

         The company's Employee Stock Ownership Plan (ESOP) became effective
January 1, 1981. Under the plan, the company contributes a percentage of each
participant's annual compensation into a trust, either as treasury stock
contributions or cash, which is then used to purchase Elcor common stock.
Employees vest 20% after three years of employment and 20% per year thereafter,
with the stock distributed at retirement, death, disability, or as authorized by
the Plan Administrative Committee. Effective January 1, 1990, the company
established an Employee Savings Plan under Internal Revenue Code section 401(k).
All employees, except those covered by plans established through collective
bargaining, are eligible for participation. Under this Plan, the company
contributes a percentage of each participant's annual compensation into a Plan
to be invested among various defined alternatives at the participants'
direction. Vesting of company contributions is in accordance with the same
schedule as that of the ESOP.

         The Board of Directors authorized total contributions of 5.0% in fiscal
1998, 4.6% in fiscal 1997 and 4.6% in fiscal 1996, of each participant's annual
compensation, as defined, including forfeitures, split equally between the ESOP
and 401(k) Plans. In addition, on January 1, 1998, the company began
contributing an additional $.50 for every $1.00 of employee contributions into
the 401(k) Plan, limited to a maximum matching of 2% of an employee's
compensation. Total contributions charged to expense for these plans were
$1,722,000, $1,245,000 and $1,120,000, in 1998, 1997 and 1996, respectively.

         The company has a Stock/Loan Plan which allows certain key employees to
borrow an amount, based on a percentage of their salaries and the performance of
their operating units, for the purpose of purchasing the company's common stock.
Under the Stock/Loan Plan, the loans, which are unsecured, and any accrued
interest are forgiven and amortized as compensation over five years of
continuing service with the company. If employment is terminated for any reason
except death, disability or retirement, the balance of the loan becomes due and
payable. Loans outstanding at June 30, 1998 and 1997 totaling $1,074,000 and
$1,078,000, respectively, are included in Other Assets.

COMMITMENTS AND CONTINGENCIES

         The company and its subsidiaries lease certain office space,
facilities, and equipment under operating leases, expiring on various dates
through 2004. Total rental expense was $1,505,000 in 1998, $1,295,000 in 1997
and $1,167,000 in 1996. At June 30, 1998, future minimum rental commitments
under noncancellable operating leases, payable over the remaining lives of the
leases, are:

         The company's subsidiaries provide certain warranties for their
products which are generally limited to being free from defect in materials or
workmanship affecting performance or meeting specified manufacturing and
material specifications. During 1998, 1997 and 1996, the company recorded to
expense approximately $1,681,000, $1,566,000 and $1,637,000, respectively, in
warranty claim settlements and reserves. The company has established reserves
for estimated probable future claims in accordance with SFAS No. 5, "Accounting
for Contingencies."

         On February 8, 1994, a wholly owned subsidiary, Elk Corporation of
Dallas (Elk) was granted a design patent covering the ornamental aspects of
certain Elk shingles. On December 6, 1994, Elk was granted a utility patent on
the functional aspects of certain Elk shingles. Elk has sued GAF Building
Materials Corporation and related GAF entities (collectively GAF) in federal
court for infringement of these patents and trade dress. In the design patent
case, Elk seeks to recover as damages the total profit that GAF has made from
the infringing shingles. In the utility patent case, Elk seeks to recover as
damages a reasonable royalty on GAF's sales of infringing shingles and certain
lost profits.

         GAF seeks a declaratory judgment that the Elk patents are not infringed
and are either invalid or unenforceable. GAF has also asserted claims for unfair
competition, Lanham Act violations based on alleged false advertising, and
common law fraud, generally praying for damages of not less than $25 million
including actual and punitive damages, plus interest, costs, and reasonable
attorney fees. Elk disputes GAF's claims, and management intends vigorously to
defend them and to enforce its intellectual property rights. In April, 1998, the
District Court for the Northern District of Texas entered a partial final
judgement against Elk in the design patent case based on an inequitable conduct
ruling and certified the case for appeal. Elk has contested that judgment in an
appeal which it has filed with the United States Court of Appeals for the
Federal Circuit. Elk expects its appeal to be decided by the Court of Appeals in
1999. In the interim, trial on the trade dress claim and 



                                       34
<PAGE>   36


certain other matters in the design patent case and trial in the utility patent
cases are unscheduled but pending.

         While management can give no assurances regarding the ultimate outcome
of the litigation, outside counsel believe that Elk will prevail on its patent
and trade dress claims and that Elk will defeat GAF's counterclaims. Even if the
outcome were to be adverse to Elk, it is not expected to have a material effect
on the company's financial position or liquidity.

         The company and its subsidiaries are involved in other legal actions
and claims arising in the ordinary course of business. Based on advice from
legal counsel, management believes such litigation and claims will be resolved
without material adverse effect on the consolidated financial statements.

         On December 1, 1985, the company became self-insured for its products
and completed operations liability exposure because the cost of insurance for
such risks was believed to be excessive for the coverage to be provided.
Reserves for estimated potential losses of this type have been established.

         The company's operations are subject to extensive federal, state and
local laws and regulations relating to environmental matters. Although the
company does not believe it will be required to expend amounts which will have a
material adverse effect on the company's consolidated financial position or
results of operations by reason of environmental laws and regulations, such laws
and regulations are frequently changed and could result in significantly
increased cost of compliance. Further, certain of the company's industrial
products operations utilize hazardous materials in their production processes.
As a result, the company incurs costs for remediation activities at its
facilities and off-site from time to time. The company establishes and maintains
reserves for such remediation activities, when appropriate, in accordance with
SFAS No. 5, "Accounting for Contingencies."

NEW ACCOUNTING STANDARDS

         In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting
Comprehensive Income," which establishes standards of reporting of comprehensive
income and its components in the consolidated financial statements. The company
will adopt SFAS No. 130 in fiscal 1999, but does not expect the adoption to
impact the company's financial position or results of operations.

         Also in June 1997, the FASB issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." SFAS No. 131 requires public
companies to disclose, among other things, certain interim and annual financial
information about the enterprise using a new management approach. The management
approach requires segment information to be reported based on how management
evaluates the operating performance of its business units or segments. The
company will adopt SFAS No. 131 in fiscal 1999 and does not currently anticipate
significant changes in its reportable segments.

         In April 1998, the Accounting Standards Executive Committee (AcSec) of
the American Institute of Certified Public Accountants issued Statement of
Position 98-5, "Reporting on the Costs of Start-Up Activities," requiring, among
other things, companies to expense on a current basis previously capitalized
start-up costs. At June 30, 1998, the company had $6,682,000 of unamortized
capitalized start-up costs. This Statement of Position is effective for
financial statements for fiscal years beginning after December 15, 1998, unless
adopted earlier. The company plans to adopt this new accounting standard in
fiscal 1999 at which time all remaining unamortized capitalized start-up costs
will be expensed and reflected in the Consolidated Statement of Operations as a
cumulative change in accounting principle.

INCOME TAXES

         The company's effective tax rate was 35.6% in 1998, 37.0% in 1997 and
37.6% in 1996. The difference between the federal statutory tax rate and the
effective tax rate is reconciled as follows:

(1)  In fiscal 1998, operating profit from the company's technology
     licensing and consulting services business exceeded 10% of consolidated
     operating profit. This business has not historically met the 10%
     reporting test nor is it typically expected to in the future. No
     separate segment is reflected in fiscal 1998 for this business unit.

(2)  Consists principally of cash and cash equivalents, trade receivables,
     inventories, and net property, plant and equipment.

                            ON SUPPLEMENTAL SCHEDULE



  To the Shareholders and Board of Directors of Elcor Corporation:


              We have audited in accordance with generally accepted auditing
  standards, the accompanying consolidated financial statements of Elcor
  Corporation and have issued our report thereon dated August 17, 1998. Our
  audit was made for the purpose of forming an opinion on those statements taken
  as a whole. The Supplemental Schedule II is the responsibility of the
  Company's management and is presented for purposes of complying with the
  Securities and Exchange Commission's rules and is not part of the basic
  financial statements. This schedule has been subjected to the auditing
  procedures applied in the audit of the basic financial statements and, in our
  opinion, fairly states in all material respects the financial data required to
  be set forth herein in relation to the basic financial statements taken as a
  whole.

Dear               :
     --------------

           Elcor Corporation (the "Company") considers it essential to its best
interests to foster the continuous employment of key management personnel and
their objective pursuit of what is in the best interests of the Company and its
shareholders.  In this connection, the Board of Directors of the Company (the
"Board") recognizes that, as is the case with many publicly held corporations,
the possibility of a change in control may exist at some time in the future.
That possibility, and the uncertainty and questions which  it may raise among
management, may result in the departure or distraction of key management
personnel to the detriment of the Company and its shareholders, whether or not
the change of control actually comes to fruition.

           The Board has determined that appropriate steps should be taken to
reinforce and encourage the continued objectivity and dedication to corporate
objectives of key members of the management of the Company and its
subsidiaries, including you, in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.  Furthermore, the Board believes that appropriate incentives should be
provided to key management personnel to assist in the transition of the Company
upon any change in control.  This letter agreement ("Agreement") is intended to
reduce or eliminate your personal loss from any change in control transaction
and thereby ensure your objective pursuit or performance of corporate strategy
and your strong commitment to the best interests of the Company and its
shareholders before and after any such transaction.

           In order to induce you to remain in the employ of the Company during
any threatened change in control, and for other good and valuable
consideration, the receipt and sufficiency of which are acknowledged, the
Company and you agree as follows:

         1.  Term and Nature of Agreement.  This Agreement will commence on the
date hereof and will continue in effect through the second anniversary of this
Agreement; provided, however, that commencing on such anniversary and each
second anniversary thereafter, the term of this Agreement will automatically be
extended for two additional years unless, not later than 30 days prior to the
end of the term in that year, either party has given notice to the other party
that it does not wish to extend this Agreement; provided, further, that,
subject to Section 3(i), this Agreement will terminate upon the termination of
your employment with the Company or its subsidiary for any reason prior to any
Change in Control, and no payments or benefits will be due hereunder if this
Agreement has terminated or expired in accordance with this Section 1 prior to
a Change in Control.  This Agreement is not an employment agreement and is
independent of the at-will employment relationship
<PAGE>   2
M
 --.  -----------------------
                      , 199
- ----------------------     ---
Page 2

between the Company or its subsidiary and you.  No term of this Agreement will
be deemed or interpreted to construe or confer rights outside of the specific
contractual relationship established by this Agreement, whether to establish a
course of dealing between the parties, to confer implied terms of employment,
to alter the status quo that you are strictly an employee-at-will of the
Company or its subsidiary, or otherwise.

           2.  Payments and Benefits.

         (i) Payable Only Upon a Change in Control.  No bonus or other payments
or benefits will be payable pursuant to this Agreement unless there has been a
Change in Control of the Company.

         (ii)  Separation Payment.  If your employment with the Company or its
subsidiary is terminated at any time within three (3) years following the
Change in Control, (A) by the Company or its subsidiary without Cause, or (B)
by you for Good Reason, then the Company will pay you a separation payment (the
"Separation Payment").  Subject to Section 4(vii), the Separation Payment will
be a lump-sum cash payment equal to ________ (___) times your Annual
Compensation.  If, however, your employment with the Company or its subsidiary
is terminated at any time (subject to Section 3(i)) prior to a Change in
Control, or is terminated after the Change in Control (A) by the Company or its
subsidiary for Cause, (B) by you without Good Reason, or (C) because of your
death or Disability, then no Separation Payment under this Agreement will be
due to you from the Company.   The Company will pay you, or cause the Escrow
Agent or L/C Issuer under Section 2(vi) to pay you upon your presentation of
documents contemplated thereby, any Separation Payment to which you are
entitled under this Section 2(ii) within ten (10) days after the effective date
of  the termination of your employment with the Company.   If you are
terminated for any reason at any time, whether before or after any Change in
Control, nothing in this Agreement will prevent the Company or its subsidiary,
as the case may be, from awarding you reasonable severance compensation to
which you have no contractual entitlement under this Agreement, if in its sole
discretion, it determines to do so, but nothing in this Agreement will be
construed to mean that the Company or its subsidiary will or is obligated to do
so.

         (iii)  No Offsets.  Any Separation Payment paid to you will not act to
reduce any other compensation, bonuses or other benefits to which you are or
may otherwise become entitled, including without limitation accrued vacation
pay, or salary or bonus that is accrued but unpaid as of the effective date of
termination of employment.  The Company will not have any rights of offset
against Separation Payments due to you hereunder, except for any tax
withholding or garnishment required under applicable law.

         (iv) Employee Welfare Benefits.  If upon a Change in Control you are
employed by the Company or its subsidiary, then for at least ________ (___)
years following the Change in Control, you and your dependents will receive the
same or substantially the same group medical, disability and life insurance
coverage through the Company as you did immediately prior to such Change in
Control
<PAGE>   3

                      , 199
- ----------------------     ---
Page 3

at no more than one-hundred twenty percent (120%) of your pre-Change in Control
employee cost; provided, however, that if your employment with the Company or
its subsidiary is terminated during such _____-year period (A) because of your
death or Disability, (B) by the Company or its subsidiary for Cause, or (C) by
you without Good Reason, then as of the effective date of your termination of
employment, you will no longer be entitled to such coverage, but you or your
representative and dependents may be entitled to elect continued coverage under
the employee  health plan(s) then offered by the Company only to the extent, if
any, mandated under the Consolidated Omnibus Budget  Reconciliation Act of
1985, as it may be amended or superseded ("COBRA").  If your employment with
the Company or its subsidiary is terminated within _____ (___) years following
the Change in Control (A) by the Company or its subsidiary without Cause, or
(B) by you with Good Reason, then you and your dependents will be entitled, to
the extent permitted under the plans and applicable law, to receive the same or
substantially the same group medical, disability and life insurance coverage as
you did immediately prior to the Change in Control, including comparable
coverage of conditions existing at the time of reference, at the same or
substantially the same cost to you as your pre-Change in Control employee cost,
for the balance of the _____-year period following the Change in Control, and
after the end of such period, you or your representative or dependents, as the
case may be, may elect continued coverage for you and your dependents under
health plans then offered by the Company or its subsidiary only for the time
and upon the terms, if any, mandated under COBRA.  Notwithstanding the
foregoing provision of Section 2(iv), if after the termination of your
employment, the Company or its subsidiary is unable under applicable law or for
any other reason to provide the same or substantially the same benefits to you
as specified above, you and the Company will negotiate in good faith for the
Company's payment or provision to you of an adequate substitute that provides
you the economic equivalent of the above benefits and the opportunity for
reasonable protection from the risks against which the above benefits would
otherwise insure.  Subject to Section 3(i), if your employment with the Company
or its subsidiary is terminated for any reason prior to a Change in Control, or
after the _____-year period following a Change in Control, your entitlement to
continued benefits will be limited to mandated health benefits under COBRA,
unless otherwise agreed by the Company or as otherwise provided in any employee
benefit plan of the Company or any subsidiary.

         (v)  Credited Service - Stock/Loan Plan.  If within three (3) years
following a Change in Control your employment with the Company or its
subsidiary is terminated (A) by the Company or its subsidiary without Cause, or
(B) by you with Good Reason, then the Company or such subsidiary, as the case
may be, will provide you and accrue the Supplemental Credited Service.
"Supplemental Credited Service" means service credits, for purposes of
forgiveness of then outstanding loans to you under the Company's Stock/Loan
Plan, sufficient to render all of your outstanding Stock/Loans from the Company
forgiven in full.

         (vi) Escrow of Funds.  Immediately prior to a Change in Control, the
Company will deposit into an insured, interest bearing escrow account (the
"Escrow Account") funds equal to the maximum Separation Payment and Gross-Up
Payment potentially payable to you pursuant to Sections 2(ii) and 
<PAGE>   4
M
 --.  -----------------------
                      , 199
- ----------------------     ---
Page 4

5(i) under the facts and circumstances at that time (the "Maximum
Payment").  The Escrow Account will be held pursuant to an escrow agreement
with a federally insured depository institution having net capital and surplus
in excess of $100,000,000.00 (the "Escrow Agent").  Such escrow agreement will
provide that immediately upon your presentation of an affidavit that all
conditions to payment of such funds to you have been met, the Escrow Agent will
pay you funds equal to any amount, up to the Maximum Payment, sworn to be due.
All amounts in excess of any amounts due to you, including interest accruing on
funds on deposit and potentially payable amounts that ultimately are not due
under the Agreement, will revert to the Company.   At the Company's option, in
lieu of the foregoing escrow securing payment to you, immediately prior to the
Change in Control the Company will provide you with an irrevocable letter of
credit from a federally insured depository institution (the "L/C Issuer")
having net capital and surplus in excess of $100,000,000.00.  Such letter of
credit will have a term extending to or beyond the third annual anniversary of
the Change in Control, and will be in an amount equal to the Maximum Payment.
The terms of the letter of credit will require the L/C Issuer to pay or honor
one or more drafts  drawn by you under the letter of credit upon your
presentation of draft(s) in any amount up to the Maximum Payment along with
your sworn, notarized affidavit stating that all conditions to payment of such
amount have been satisfied. You will be entitled to provide the sworn affidavit
that the Separation Payment and Gross-Up Payment are due at the respective
times provided for such payments under Section 2(ii) and 5(ii) of this
Agreement.  The escrow agreement or letter of credit reimbursement agreement
between the Company and the Escrow Agent or L/C Issuer, as the case may be,
will provide such financial institution with indemnities and exculpation from
liability as is reasonable and sufficient to permit it to perform its duties in
accordance with Section 2(vi) without threat of liability except for such
institution's willful misconduct.

         3.  Other Agreements.

         (i)  No Circumvention of Agreement.  Any termination of your
employment without Cause by the Company, and any reduction of compensation,
including a reduction of benefits under a material employee compensation,
benefit, or welfare plan, or other action which would constitute Good Reason if
it occurred after a Change in Control, if made prior to the Change in Control
but during the term of this Agreement, or any notice of termination or
expiration of this Agreement given by the Company in accordance with Section 1,
which is at the instance, request, suggestion or because of the influence or
upon the suggestion of another party to the transaction resulting in the Change
in Control, or its affiliate or associate, or any other transaction designed to
circumvent the intent and purposes of this Agreement, upon the Change of
Control will be treated, solely for purposes of the Company's payment and other
obligations to you under this Agreement, as a termination of your employment by
the Company without Cause, immediately after the effective time of the Change
in Control.

         (ii) No Obligation to Mitigate.  You will not be required to mitigate
the amount of any payment or benefit provided for in this Agreement by seeking
other employment or otherwise, nor
<PAGE>   5
M
 --.  -----------------------
                      , 199
- ----------------------     ---
Page 5

will the amount of any payment or benefit provided for in this Agreement be
reduced by any compensation or benefit earned by you as the result of
employment by another employer, by retirement benefits, by offset against any
amount claimed to be owed by you to the Company or its subsidiary, or
otherwise;  provided, that payments by the Company or its subsidiary designated
as payments under this Agreement will be credited against the obligations under
this Agreement whether or not the payor entity is the Company; and provided,
further, that if you are reemployed while covered by the welfare benefits set
forth in Section 2(iv), and become covered under your new employer's employee
welfare plans, your entitlement to the benefits set forth in Section 2(iv)
thereupon will cease, except to any extent mandated otherwise by COBRA.  You
will provide the Company with immediate notice of such  reemployment and
coverage, and to the extent that you fail to do so, you will be obligated to
reimburse the Company or its subsidiary for its costs of providing you non-
mandatory benefits under Section 2(iv) subsequent to your reemployment date,
with interest at a rate of twelve percent (12%) per annum, compounded monthly.

         4.  Certain Definitions.   For purposes of this Agreement, the
following terms denoted by capitalization of initial letters will have the
definitions below:

         (i)  Annual Compensation.  "Annual Compensation" means the highest
annual total of base salary, bonuses (including without limitation amounts paid
under the applicable Incentive Cash Bonus Plan) and commissions paid to you by
the Company and/or any of its affiliates, without reduction for any deductions,
withholding, reductions or deferrals, in the three calendar years ending before
the date of the Change in Control.  For purposes of the preceding definition,
only years in which you were employed by the Company or its subsidiary are
included in the calculation of Annual Compensation, and compensation will be
annualized for any partial years of such employment within the three calendar
years ending before the date of the Change in Control.

         (ii) Beneficial Owner.  "Beneficial Owner" and its derivatives means
any Person (as defined in Section 4(viii)) who, directly or indirectly, through
any contract, trust, power of attorney, pooling or other arrangement,
understanding, relationship or otherwise has or shares voting power, which
includes the power to vote or direct the voting of a security, and/or
investment power, which includes the power to dispose or direct the disposition
of such security; provided however that for purposes of this Agreement,
Beneficial Ownership will not be deemed to result solely by virtue of a
Person's right to acquire a security under any agreement, arrangement or
understanding, including without limitation any option, conversion or exchange
rights, warrants or option, until such rights are actually exercised or
asserted, as the case may be; and provided, further, that no Person will be
deemed to be a Beneficial Owner of securities solely as a result of acting as a
member of the proxy committee appointed by the Board, or by virtue of a
revocable proxy given in response to a public proxy or consent solicitation
made in accordance with the Exchange Act; and, provided further, that no Person
ordinarily engaged in business as an underwriter of securities will be deemed a
Beneficial Owner of any securities acquired through such person's participation
in good faith in a firm commitment

- ----------------------     ---
Page 6

underwriting until the expiration of forty days after the date of such
acquisition and then only if such securities continue to be owned by such
Person at the end of such forty day period.

         (iii)  Cause.  Termination by the Company or its subsidiaries of your
employment for "Cause" means termination upon (A) your willful and continued
failure to substantially perform your duties with the Company or its subsidiary
(other than any such failure resulting from your incapacity due to physical or
mental illness, or any actual or anticipated failure of your performance after
the Company's issuance of a notice of termination or your issuance of a notice
of termination for Good Reason), after a written demand for substantial
performance is delivered to you by the Board, which demand specifically
identifies the manner in which the Board believes that you have not
substantially performed your duties, (B) your willful conduct which is
demonstrably and materially injurious to the Company or its subsidiary,
monetarily or otherwise, or (C) your felony conviction for a violation of a
criminal law.  For purposes of this Section 4(iii), no act, or failure to act,
on your part will be deemed "willful" unless done, or omitted to be done, by
you without good faith and without reasonable belief that your action or
omission was in or not opposed to the best interests of the Company.  Not in
limitation of the foregoing, "Cause" does not include (W) acts or omissions
attributable to bad judgment or gross negligence unless due to willful,
habitual and continued bad judgment or gross negligence, (X) any act or
omission in respect of which a determination could properly be made that you
met the applicable standard of conduct prescribed for indemnification or
reimbursement or payment of expenses under the Certificate of Incorporation and
Bylaws of the Company, the laws of the State of Delaware, or the directors' and
officers' liability insurance of the Company, in each case as in effect at the
time of such act or omission, (Y) an act or omission which occurred more than
twelve (12) calendar months prior to your having been given notice of the
termination of your employment for such act or omission, unless the commission
of such act or such omission could not at the time of such commission or
omission have been known to a member of the Board (other than you, if you are
then a member of the Board), until less than twelve (12) calendar months before
such notice is given, or (Z) a continuing course of action which commenced and
was or could reasonably have been known to a member of the Board (other than
you, if applicable) more than twelve (12) calendar months prior to notice
having been given to you of the termination of your employment.  Any act, or
failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the chief executive officer or
chief administrative officer of the Company or based upon the advice of counsel
for the Company will be conclusively presumed to be done, or omitted to be
done, by you in good faith and in the best interests of the Company.
Furthermore, notwithstanding anything to the contrary, you will not be deemed
to have been terminated for Cause unless and until there will have been
delivered to you a copy of a resolution duly adopted by the affirmative vote of
not less than three-quarters (3/4) of the entire membership of the Board (other
than you, if you are then a member of the Board) at a meeting of the Board
called and held for such purpose (after reasonable notice to you and an
opportunity for you, together with your counsel, to be heard before the Board),
finding that in the good faith opinion of the Board you were guilty of conduct
constituting "Cause" pursuant to this Section 4(iii) and specifying the
particulars thereof.

          (iv) Change in Control.   "Change in Control" means the consummation
of a transaction or series of transactions having the effect of changing
possession, direct or indirect, of the power to direct or cause the direction
of the management and policies of the Company or its successor through the
Beneficial Ownership of voting securities of the Company or its successor, by
contract or otherwise; provided, that, without limitation, such a Change in
Control will conclusively be deemed to have occurred if:

                 (A) any Person is or becomes the Beneficial Owner of voting
         securities of the Company representing forty (40%) or more of the
         combined voting power of the Company's then outstanding voting
         securities; or

                 (B)  a merger or consolidation of the Company with any other
         entity becomes effective, other than (i) a merger or consolidation
         which would result in the voting securities of the Company outstanding
         immediately prior thereto continuing to represent (either by remaining
         outstanding or by being converted into voting securities of the
         surviving entity) at least sixty percent (60%) of the combined voting
         securities of the Company or such surviving entity outstanding
         immediately after such merger or consolidation or (ii) a merger or
         consolidation effected to implement a recapitalization of the Company
         (or similar transaction) in which no Person acquires forty percent
         (40%), or more of the combined voting power of the Company's then
         outstanding securities; or

                 (C) the shareholders of the Company approve a plan of complete
         liquidation of the Company or the shareholders of the Company or Board
         approve an agreement or plan for the sale or disposition by the
         Company in one transaction or a series of transactions resulting in
         the acquisition by any Person of operating assets or earning power
         constituting more than sixty-seven percent (67%) of the fair market
         value of all operating assets or earning power of the Company and its
         subsidiaries, taken as a whole;

provided, that no Change in Control will be deemed to have occurred solely by
virtue of changes of the composition of the Board, without changes in
Beneficial Ownership of the Company or its successor.

         (v) Continuing Director.  "Continuing Director" will mean (A) any
member of the Board as of the date of this Agreement (a "Current Director"),
(B) any person who subsequently becomes a member of the Board if such Person's
election or nomination for election to the Board is recommended or approved by
a majority of directors who are Current Directors (an "Approved Director"), or
(C) any person who subsequently becomes a member of the Board if such Person's
election or nomination for election to the Board is approved by a majority of
any and all Current Directors and Approved Directors then serving on the Board.

           (vi)  Disability.  "Disability" means your incapacity due to
physical or mental illness which results in your absence from the full-time
performance of your duties with the Company or its subsidiary for six (6)
consecutive months, and within thirty (30) days after written notice of
termination is given you have not returned to the full-time performance of your
duties.

         (vii)  Good Reason.  "Good Reason" means without your express written
consent, the occurrence after a Change in Control of the Company of any of the
following circumstances:

                 (A) the assignment to you of any duties that you believe in
         good faith  to entail a substantial increase in your exposure to
         potential personal liability (whether or not indemnifiable by the
         Company) or a substantial increase in occupational risk to your
         personal health or safety, or the assignment to you for a period in
         excess of twelve months of any untitled, reduced or other capacity not
         reasonably required to accomplish the transition to new control,
         including but not limited to titled or untitled, advisory or
         consulting positions; or

                 (B) a reduction by the Company or its subsidiary in your
         annual base salary or a reduction in the basis on which you
         participate in any material employee compensation, benefit, or welfare
         plan of the Company or its subsidiary, as in effect immediately prior
         to the Change in Control, other than an increase in your employee
         share of premiums for such a plan which, cumulatively with any other
         increases post-Change in Control, totals to no more than 20% of your
         pre-Change in Control employee share of premiums; or

                 (C) the Company's or its subsidiary's requiring you to be
         based more than fifty (50) miles further from your residence than are
         the offices at which you were principally employed immediately prior
         to the date of the Change in Control, except for required travel on
         the business of the Company or its subsidiary that is no more than is
         reasonable, for which purpose travel substantially consistent with
         your present business travel obligations will be conclusively presumed
         to be reasonable; or

                 (D) the failure by the Company or its subsidiary to pay to you
         any portion of your salary, bonus, or any other compensation due to
         you under any deferred compensation program, or benefit under any
         employee compensation, benefit or welfare plan then in effect, within
         ten (10) days of the date such compensation or benefit is due; or

                  (E) the failure by the Company or its subsidiary to continue
         in effect any material employee compensation, benefit or welfare plan
         in which you participate immediately prior to the Change in Control,
         unless reasonably equivalent benefits or an equitable arrangement
         (embodied in an ongoing substitute or alternative plan) have

         been made with respect to such plan, or the failure by the Company or
         its subsidiary to continue your participation therein (or in such
         substitute or alternative plan) on a basis not materially less
         favorable, as to terms of  and amount of benefits provided to you,
         than existed at the time of the Change in Control; or

                 (F) the failure by the Company or its subsidiary to provide
         you with a substantially equivalent number of paid vacation days (or
         compensation in lieu thereof) to which you are entitled on the basis
         of your years of service with the Company or its subsidiaries in
         accordance with the normal vacation policy applicable to you
         immediately prior to the Change in Control; or

                 (G) the failure of the Company to obtain a satisfactory
         agreement from any successor or other party to assume and agree to
         perform this Agreement as contemplated under Section 6, or the breach
         by the Company or its subsidiary of this Agreement;

provided, however, that none of the circumstances set forth in foregoing
clauses (A) - (G) will constitute "Good Reason" unless and until you provide
the Company with written notice of the circumstance and thirty (30) days to
cure or remedy such circumstance; provided further that if after the Company
cures or remedies any such circumstance once and it reoccurs, or if the Company
remedies more than three distinct circumstances, recurring or not recurring, no
notice and opportunity to cure or remedy  will be required before such
circumstance constitutes Good Reason.  Anything to the contrary in this
Agreement notwithstanding, a termination of employment by you for ANY reason
during the thirty-day period (the "Thirty-day Window Period") immediately
following the first anniversary of the Change in Control will be deemed to be a
termination by you with Good Reason for all purposes of this Agreement,
provided, however, that any such termination by you during the Thirty-day
Window Period for any reason not set forth in the foregoing clauses (A)-(G)
will act to reduce the Separation Payment, to which you are then entitled for a
termination with Good Reason under Section 2(ii), by one times your Annual
Compensation.

         (viii) Person.  "Person" means any person or entity, or group or
association of the foregoing, other than (1) the Company, (2) any trustee,
investment advisor or other fiduciary holding, voting or otherwise exercising
control of securities under the Company's Second Amended and Restated Employee
Stock Ownership Plan dated January 1, 1994 (as amended, the "ESOP") or any
successor employee plan to the ESOP, (3) any other employee benefit plan or
employee compensation arrangement approved by Continuing Directors of the
Company, (4) any corporation owned, directly or indirectly, by the shareholders
of the Company in substantially the same proportions (relative to other
shareholders individually and in the aggregate) as their ownership of stock of
the Company, or (5) you or any group in which you are a participant, prior to
the consummation of the Change in Control, through your beneficial ownership of
equity securities; provided, however, that you will not be deemed a participant
in any group solely by virtue of being a Beneficial Owner of an investment of
$250,000.00 or less of publicly traded securities.

         5.  Certain Tax Impacts.

         (i) Gross-Up.  Anything in this Agreement to the contrary
notwithstanding and except as set forth below, if it is determined that any
payment or distribution by the Company to or for the benefit of you (whether
paid or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise), but determined without regard to any additional
payments required under this Section 5 (a "Payment") would be subject to the
excise tax imposed by Section 4999 of the Code or any interest or penalties are
incurred by you with respect to such excise tax (collectively, the "Excise
Tax"), then the Company (or its Escrow Agent or L/C Issuer, as the case may be)
will make an additional payment (a "Gross-Up Payment") in an amount such that
after payment by you of all taxes (including any interest or penalties imposed
with respect to such taxes), including, without limitation, any income taxes
(and any interest and penalties imposed with respect thereto) and Excise Tax
imposed upon the Gross-Up Payment, you retain an amount of the Gross-Up Payment
equal to the Excise Tax imposed upon the Payments.

         (ii) Certain Tax Determinations.  Subject to the provisions of Section
5(iii), all determinations required to be made under this Section 5, including
whether and when a Gross-Up Payment is required and the amount of such Gross-Up
Payment and the assumptions to be utilized in arriving at such determination,
will be made by Arthur Andersen LLP or such other certified public accounting
firm as may be designated by you (the "Accounting Firm").  The Accounting Firm
will provide detailed supporting calculations both to the Company and you
within 15 business days of the receipt of notice from you that there has been a
Payment, or such earlier time as is requested by the Company.  If the
Accounting Firm is serving as consultant, accountant or auditor for the
individual, entity or group effecting the Change in Control, you will appoint
another nationally recognized accounting firm to make the determinations
required hereunder (which accounting firm will then be referred to in this
Agreement as the Accounting Firm).  All fees and expenses of the Accounting
Firm will be borne solely by the Company.  Any Gross-Up Payment, as determined
pursuant to this Section 5, will be paid by the Company (or its Escrow Agent or
L/C Issuer) to you within five days of the receipt of the Accounting Firm's
determination.  Any determination by the Accounting Firm will be binding upon
the Company and you.  As a result of the uncertainty in the application of
Section 4999 of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Gross-Up Payments which will not
have been made by the Company should have been made ("Underpayment"),
consistent with the calculations required to be made hereunder.  If the Company
exhausts its remedies pursuant to Section 5(iii) and you thereafter are
required to make a payment of any Excise Tax, the Accounting Firm will
determine the amount of the Underpayment that has occurred and any such
Underpayment will be promptly paid by the Company (or its Escrow Agent or L/C
Issuer) to you.

         (iii) Certain Tax Claims.  You will notify the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require
the payment by the Company of the Gross-Up Payment.  Such notification will be
given as soon as practicable but not later than ten business days
<PAGE>   11
M
 --.  -----------------------
                      , 199
- ----------------------     ---
Page 11

after you are informed in writing of such claim and will apprise the Company of
the nature of such claim and the date on which such claim is requested to be
paid.  You will not pay such claim prior to the expiration of the 30-day period
following the date on which you give such notice to the Company (or such
shorter period ending on the date that any payment of taxes with respect to
such claim is due).  If the Company notifies you in writing prior to the
expiration of such period that it desires to contest such claim, you will:

                 (A) give the Company any information reasonably requested by
         the Company relating to such claim;

                 (B) take such action in connection with contesting such claim
         as the Company reasonably requests in writing from time to time,
         including, without limitation, accepting legal representation with
         respect to such claim by an attorney reasonably selected by the
         Company;

                 (C) cooperate with the Company in good faith in order
         effectively to contest such claim; and

                 (D) permit the Company to participate in any proceedings
         relating to such claim;

provided, however, that the Company will bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and will indemnify and hold you harmless, on an after-tax
basis, for any Excise Tax or income tax (including interest and penalties with
respect thereto) imposed as a result of such representation and payment of
costs and expenses.  Without limitation on the foregoing provisions of this
Section 5(iii), the Company will control all proceedings taken in connection
with such contest and, at its sole option, may pursue or forego any and all
administrative appeals, proceedings, hearings and conferences with the taxing
authority in respect of such claim and may, at its sole option, either direct
you to pay the tax claimed and sue for a refund or to contest the claim in any
permissible manner, and you agree to prosecute such contest to a determination
before any administrative tribunal, in a court of initial jurisdiction and in
one or more appellate courts, as the Company will determine; provided, however,
that if the Company directs you to pay such claim and sue for a refund, the
Company will advance the amount of such payment to you, on an interest-free
basis and will indemnify and hold you harmless, on an after-tax basis, from any
Excise Tax or income tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and further provided that any extension of the statute
of limitations relating to payment of taxes for your taxable year with respect
to which such contested amount is claimed to be due is limited solely to such
contested amount.  Furthermore, the Company's control of the contest will be
limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and you will be entitled to settle or contest, as the case may be,
any other issue raised by the Internal Revenue Service or any other taxing
authority.

         (iv) Refunds of Tax Advances.  If, after the receipt by you of an
amount advanced by the Company pursuant to Section 5(iii), you become entitled
to receive any refund with respect to such claim, you will (subject to the
Company's complying with the requirements of Section 5(iii)) promptly pay to
the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto).  If, after the receipt by you
of an amount advanced by the Company pursuant to Section 5(iii), a
determination is made that you will not be entitled to any refund with respect
to such claim and the Company does not notify you in writing of its intent to
contest such denial of refund prior to the expiration of 30 days after such
determination, then such advance will be forgiven and will not be required to
be repaid and the amount of such advance will offset, to the extent thereof,
the amount of Gross-Up Payment required to be paid.

         6.  Successors.  If the transaction effecting the Change in Control of
the Company would not as a matter of law result in the Company's successor's or
other appropriate entity being bound to this Agreement, the Company will
require an entity that succeeds in such transaction to at least a majority of
the business and/or assets of the Company, or any other involved entity with
whom you accept employment, to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place.

         7.  Notices.  For the purpose of this Agreement, notices and all other
communications provided for in the Agreement will be in writing and will be
deemed to have  been duly given when delivered or mailed by personal delivery,
confirmed telefacsimile or United States registered mail, return receipt
requested, postage prepaid, addressed to the respective addresses set forth on
the first page of this Agreement, provided that all notices to the Company will
be directed to the attention of  the Board or Chief Executive Officer with a
copy to the General Counsel of the Company, or to such other address as either
party may have furnished to the other in writing in accordance herewith, and no
notice will be effective until received.

         8.  Survival.  Any rights and obligations of the Company or you
hereunder arising upon a Change in Control during the term of this Agreement
will survive the expiration or termination of this Agreement.

         9.  Legal Expenses; Special Damages; Arbitration.

         (i) The Company will reimburse all reasonable legal and accounting
fees and expenses incurred by you as a result of or in connection with your
enforcement of your rights under this Agreement, including all such reasonable
fees and expenses, if any, incurred in seeking to obtain or enforce payment
under this Agreement or in connection with any tax audit or proceeding to the
extent set forth in Section 5.  The Company will make such reimbursement
payments to you within ten (10) days after any such reasonable fees or expenses
are incurred and you have submitted copies of invoices therefor to the Company.

         (ii) If the Company withholds any material compensation or benefit
under this Agreement and it is subsequently determined in an arbitration or
judicial proceeding that you were due such amount, then in addition to any
compensatory damages you will be entitled to special damages equal to the
greater of (a) $25,000.00, or (b) three times your actual damages, but not to
exceed $100,000, as the arbitrator or judicial authority will assess in its
discretion.

          (iii) Any dispute or controversy arising under or in connection with
this Agreement will be settled exclusively by arbitration conducted before a
panel of three arbitrators in Dallas, Texas in accordance with the rules of the
American Arbitration Association then in effect.  Judgment may be entered on
the arbitrators' award in any court having jurisdiction.

         (iv)  Notwithstanding any of the above provisions of Section 9, you
will not be entitled to recover any legal fees or expenses (A) incurred by you
in connection with any such claim which is determined by arbitration in
accordance with Section 9(iii) of this Agreement to be frivolous or entirely
without merit, or (B) directly attributable to claims or damages which are not
contractual claims or damages for breaches of this Agreement.

         10.  Applicable Law.  Except for matters of corporate governance and
the internal affairs of the Company bearing on this Agreement, which will be
governed by the laws of the State of Delaware, this Agreement will be construed
and enforced according to the laws of the State of Texas and the federal laws
of the United States, excluding the laws of those jurisdictions pertaining to
the resolution of conflicts of laws with other jurisdictions.  Subject to
Section 9(iii): (A) the proper venues for all legal proceedings arising out of
this Agreement are Dallas County, Texas, in a state court proceeding, and the
Northern District of Texas, in a federal court proceeding, and the parties
hereby waive any defense, whether asserted by motion or pleading, that such
venue is improper, and (B) the parties consent to the personal jurisdiction of
both the courts of the State of Texas and the United States District Court for
the Northern District of Texas with respect to any litigation arising out of
the Agreement.

         11.  Binding Effect.  The obligations of the parties will be binding
on and inure to the benefit of their respective heirs, successors, assigns, and
affiliates.

         12.  Integration.  This Agreement constitutes the parties' entire
agreement containing its subject matter; provided, however, the Company or its
subsidiary and you are parties to an Employee Agreement defining certain rights
and obligations you have with respect to Company Private Information,
Inventions, and certain other matters defined therein, which Employee Agreement
will remain in effect in accordance with its terms.  No agreements or
representations, oral or otherwise, express or implied, with respect to the
subject matter of this Agreement have been made by either party which are not
expressly set forth in this Agreement.  Subject to the provisions of Section 1
for automatic term extensions, a waiver, discharge, amendment, modification, or
termination of this Agreement or any provision hereof, will be valid and
effective only if in writing and executed by both

parties hereto. A written waiver of a right, remedy or obligation under a
provision of this Agreement will not constitute a waiver of the provision
itself, a waiver of any succeeding right, remedy or obligation under the
provision, or a waiver of any other right, remedy, or obligation under this
Agreement.  Any delay or failure by a party in enforcing any obligation or in
exercising any right or remedy, including without limitation your delay in
exercising your right to terminate your employment for Good Reason during the
three-year period following a Change in Control and thereupon receive the
benefits specified in this Agreement, will not operate as a waiver of it or
affect that party's right later to enforce the obligation or exercise the right
or remedy, and a single or partial exercise of a right or remedy by a party
does not preclude any further exercise of it or the exercise of any other right
or remedy of that party.

         13.  Severability.  If any provision of this Agreement is held by a
court, arbitrator or other tribunal  of competent jurisdiction to be invalid,
void or unenforceable in any respect or with respect to any matter, such
provision in all other respects and with respect to all other matters, and the
remaining provisions with respect to all matters, will nevertheless continue in
full force and effect without being impaired or invalidated and will be
enforced to the full extent permitted by law.

         14.  Construction.  Unless the context of this Agreement otherwise
requires, (a) words of any gender will be deemed to include each other gender;
(b) the words "herein," "hereof" and "hereunder" and other words of similar
import refer to this Agreement as a whole and not to any particular article,
section, paragraph, or other subdivision, (c) words using the singular or
plural tense will also include the plural or singular tense, respectively; (d)
the terms "Section" or "subsection" will refer to the specified Section or
subsection of this Agreement; (e) the terms of any provision of COBRA, the
Exchange Act, the Code, or any other statute, regulation, form or part thereof
will be deemed also to refer to successor provisions to such provisions; (f)
the phrase "termination of employment" and equivalent phrases will not include
reassignment, without a break in service in excess of two weeks, to another
affiliate, division or department of the Company or any of its subsidiaries;
(g) the headings of the sections of this Agreement are inserted for convenience
only and will not be deemed to constitute part of this Agreement or to affect
its construction.

                  prescribed by the Company, shall bear interest at a rate that

         The President or his delegate shall designate those employees of the
         Company and its Subsidiaries qualifying as Key Employees that will be
         Participants in the Plan, and will determine the Loan Percentage
         applicable to each Key Employee. The information shall be transmitted
         to the Controller of the Company who will formulate a list of those of
         the designated Key Employees who receive a 

                                      - 2 -

<PAGE>   3


         quarterly distribution under an Incentive Bonus Plan and shall
         calculate the Loan Rights of each Key Employee by multiplying the gross
         quarterly distribution for the Key Employee by the Loan Percentage.
         Such Key Employees who receive Loan Rights in a quarter will be
         notified of their respective Loan Rights, which notification shall
         indicate the period during which the Key Employee may apply to the
         Company for a Loan, including the Prescribed Expiration Date. If the
         Key Employee desires to apply for the Loan, on or after, but in no
         event later than the Prescribed Expiration Date, the Key Employee may
         make application, on a prescribed form, to the Company for a Loan. Upon
         such timely application, the Key Employee will be required to execute
         and deliver a Promissory Note, at which time the Company will either
         issue its check in the amount of the Loan, or forward the Loan proceeds
         to ChaseMellon Shareholder Services, or any successor agent, for
         purchase of Stock through the Employee Stock Purchase Plan, as
         indicated by the Participant. This Loan shall be used only for the
         purpose of having the Key Employee (or the Key Employee and his or her
         spouse) purchase Stock. If the Participant chooses to receive a check,
         it is his or her responsibility to effect a purchase of the Stock of
         the Company. Within six months of the disbursement of the Loan, the
         Participant is further obliged to furnish to the Controller of the
         Company evidence satisfactory to the Company that such purchase was
         made. If the Stock is purchased under the Employee Stock Purchase Plan
         by appropriate election on the Promissory Note then no additional
         evidence is required to be furnished by the Participant. Any Stock
         purchased pursuant to this Plan is the sole property of the
         Participant, the Company having no claim against such Stock as
         collateral for the Loan or for any other purpose.

         This Plan shall continue each quarter in which distributions are made
         under the Incentive Bonus Plan unless and until this Plan is modified
         or terminated. If a designated Key Employee does not receive any
         Incentive Bonus Plan distribution in a particular quarter, such Key
         Employee shall not be entitled to any Loan Rights for that quarter.
         During periods before their respective Prescribed Expiration Dates,
         Loan Rights may be accumulated by the Participant and exercised as a
         whole or in any part. Any Loan Rights not exercised by the Prescribed
         Expiration Date shall expire.

         The President may prescribe, in his sole discretion, any reasonable
         administrative rules for the carrying out of the terms and provisions
         of the Plan that are consistent with the Plan.

4.       REPAYMENT OR SATISFACTION OF LOANS

         Loans made under the provisions of the Plan shall be repaid or
         satisfied by the Participant on one of the following bases:

         (a)      The Company will, at the end of 12 months following the date
                  of a Loan, forgive 20 percent of the original principal amount
                  of such Loan, together with all accrued and unpaid interest on
                  all outstanding principal of such Loan, if the Participant has
                  remained continuously in the employ of the Company or a
                  Subsidiary for such year, and the Company shall continue to
                  forgive a like 20 percent of the principal of the Loan
                  together with all accrued and unpaid interest at the
                  expiration of each of the 

                                      -3-
<PAGE>   4

                  next four years of continuous employment. For the purposes of
                  this provision, each Loan at the end of any quarter shall be
                  treated separately, i.e., if a Participant made a Loan at the
                  end of each quarter during a year, then with continued
                  employment there would be four separate instances of Loan
                  forgiveness at the end of the appropriate quarters in the
                  following year and each subsequent year of continued
                  employment.

         (b)      Upon the date of the Key Employee's retirement at or
                  subsequent to the Normal Retirement Age, or upon his/her
                  termination of employment with the Company by reason of death,
                  or total and permanent disability, as determined by the Social
                  Security Administration, the Company will forgive any amounts
                  not yet forgiven on any Loans outstanding under the Plan,
                  together with all accrued and unpaid interest, so long as the
                  Key Employee has been continuously employed by the Company or
                  a Subsidiary through such date.

         (c)      If the Participant terminates employment with the Company or
                  any Subsidiary without immediate employment by a Subsidiary or
                  the Company, whether as a result of the Participant's or the
                  Company's actions, the Participant shall be obligated to
                  immediately repay to the Company any amounts still
                  outstanding, and not yet forgiven, on all Loans under this
                  Plan, including interest on the principal of such Loan amounts
                  in accordance with this Plan and the applicable Promissory
                  Note. Such repayment shall be made by the Participant no later
                  than the last day of employment with the Company unless
                  specific arrangements are made with the Company to pay at a
                  later date. Any deferral of payment past the last day of
                  employment will cause any balances due under the Loans to bear
                  interest at a rate equal to the greater of (i) the stated
                  interest rate in the Promissory Note and (ii) ten percent
                  (10%) per annum until paid. It is the intent of the Company to
                  use whatever legal means are available to insure that all
                  balances owing the Company by terminating Participants be
                  repaid.

5.       PARTICIPANT'S RESPONSIBILITIES

         A Participant will have unrestricted right and title to any Stock
         purchased by such Participant with proceeds from a Loan and, subject to
         any applicable restrictions under the securities laws, may at any time
         sell the Stock so acquired. It is the intent of the Company under this
         Plan, however, to provide long-term incentives. Recognizing that a
         Participant may have the need to sell some of his Stock for personal
         financial reasons, the Company believes that a Participant's sale of
         some of the Stock is not so inconsistent with the Company's purposes
         for this Plan as to frustrate the Company's intent. Accordingly, at
         such time as any Participant sells a cumulative amount in excess of 25
         percent of the Participant's Stock holdings acquired as a result of the
         Plan, such 25 percent being measured on a cumulative basis, the Company
         may, depending on the facts and circumstances surrounding cumulative
         sales of Stock in excess of 25 percent, deny or reduce the amount of
         the Participant's Loan Rights which would otherwise be granted for one
         or more quarterly periods in the future. However, the Company 

                                      -4-
<PAGE>   5

         will attempt to recognize that needs of children, purchasing a new
         residence, unusual medical costs or expenses, and other hardship needs
         may qualify as acceptable reasons for selling in excess of the
         cumulative 25 percent limitation without affecting future Loan Rights.

6.       COMPANY'S RESPONSIBILITIES

         The Company reserves the right to modify, amend, or terminate this Plan
         at any time, subject only to the restriction that any Key Employee
         shall continue to be entitled to exercise any Loan Rights previously
         granted through the Prescribed Expiration Date of such Loan Rights as
         provided in the Plan and the Company will not modify the Loan repayment
         terms applicable to outstanding loans in a manner which would be
         adverse to a Participant having Loans outstanding without that
         Participant's consent.

7.       FEDERAL TAX IMPLICATIONS

         The Company or a Subsidiary shall withhold from payments of a Key
         Employee's compensation payable any and all amounts that are required
         to be withheld under federal and state law by virtue of any transaction
         or Loan forgiveness occurring pursuant to this Plan.

                              QUESTIONS AND ANSWERS

                       ELCOR KEY EMPLOYEE STOCK/LOAN PLAN
                                 (JUNE 29, 1998)

The following questions and answers are provided to give Key Employees a better
understanding of the operation and administration of the Loan Plan.

Q.       WHO IS ELIGIBLE TO PARTICIPATE?

A.       Only those "Key Employees" of Elcor or its subsidiaries who are
         designated as Participants by the President of Elcor or his delegate.

Q.       WHAT DOES THE PLAN DO?

A.       It provides, under certain conditions, the opportunity for periodic
         loans to Key Employees for the purchase of Elcor Common Stock as a
         long-term investment.

Q.       HOW MUCH WILL BE LOANED BY THE COMPANY?

A.       Different amounts depending on the performance of both the Company and
         the Participant. Participants will have right to borrow amounts up to a
         designated percentage of each quarterly Incentive Bonus Plan payment
         paid to him/her, if any.

Q.       WILL THERE BE LOANS EACH QUARTER?

A.       Only in those quarters where a Key Employee receives an Incentive Bonus
         Plan payment.

Q.       WHAT ARE THE REPAYMENT TERMS OF THE LOAN?

A.       In each year of continuous employment, 20 percent of the original
         principal amount of each Loan, together with all accrued and unpaid
         interest on such Loan, is forgiven so that five years' continuous
         service will cause the loan to be satisfied in full. Loans, including
         principal and accrued interest, to the extent not forgiven, will be due
         upon a Participant's leaving continuing service with the Company or a
         related entity.

Q.       WHAT IF THE PARTICIPANT QUITS OR THEIR EMPLOYMENT IS TERMINATED?

A.       The loan must be paid in cash by the final employment date. Of course,
         the amount due will be the balance of the loan, after deducting amounts
         already forgiven, with interest.


                                      - 6 -

<PAGE>   7

Q.       WHAT IS THE INTEREST RATE ON THE LOAN?

A.       Interest is charged according to the current "mid-term rate" published
         by the Internal Revenue Service at the time a loan is made. However,
         interest on any amounts still owed after leaving employment will accrue
         at the greater of the rate stated in the Promissory Note or ten
         percent. You can find the applicable mid-term rate in the Internal
         Revenue Bulletin published monthly by the Internal Revenue Service or
         by calling Elcor's Controller. Once the loan is made the rate will be
         fixed and will be stated on the promissory note evidencing the loan.

Q.       WHAT IF THE EMPLOYEE RETIRES AFTER REACHING NORMAL RETIREMENT
         AGE, DIES, OR BECOMES TOTALLY AND PERMANENTLY DISABLED?

A.       In such instances, any amounts still owed on the loan are forgiven.

Q.       CAN THERE BE MORE THAN ONE LOAN OUTSTANDING?

A.       Yes. In fact, it is possible after the Plan has been in operation for a
         few years to have as many as 19 loans outstanding in various stages of
         forgiveness.

Q.       WILL ANY LOAN NEED TO HAVE COLLATERAL OR SOMETHING PUT UP AS
         SECURITY?

A.       No. All loans will be made on the employee's signature and general
         credit.

Q.       CAN LOANS BE USED FOR PURPOSES OTHER THAN PURCHASING ELCOR
         STOCK?

A.       No.

Q.       WILL THE STOCK BE RESTRICTED IN ANY WAY?

A.       Generally not. If purchased in an ordinary broker's transaction on the
         New York Stock Exchange or by ChaseMellon Shareholder Services under
         the Elcor Employee Stock Purchase Plan, the stock will be unrestricted
         and generally may be sold at any time. However, at least three
         considerations may affect the timing and amount of a Participant's sale
         of Elcor Stock purchased with loans under the Plan. First, the Plan
         does generally require that each Participant maintain holdings of Elcor
         Stock equal to at least 75 percent of the total Stock cumulatively
         purchased under the Plan as a condition to receiving any further Loans.
         Second, it is unlawful for any employee of Elcor or its subsidiaries to
         buy or sell Elcor Stock based upon material "inside" information about
         Elcor (non-public information that would be important to an investor,
         such as undisclosed earnings, major pending transactions, outcomes of
         lawsuits, or other corporate information or events that have not been
         made public). Third,

                                      -7-
<PAGE>   8

         certain Elcor officers are restricted as to the timing, amounts, and
         manner of sale of shares under Rule 144 and Section 16(b) of the
         federal securities laws.

Q.       DOES STOCK IN THE PARTICIPANT'S ESOP ACCOUNT APPLY TOWARDS THE
         75 PERCENT HOLDINGS REQUIREMENT?

A.       No, because stock in the ESOP is purchased with Company, not employee,
         contributions and is also intended for long-term investment purposes.

Q.       WHAT HAPPENS IF MORE THAN 25 PERCENT IS SOLD?

A.       Falling below the 75 percent requirement may cause the Participant to
         lose future loan rights. Sales in excess of 25 percent of the
         cumulative Stock purchased under the Plan are not consistent with the
         purposes for the Plan. However, where the Participant needs to sell
         more Stock for valid financial needs such as purchasing a home,
         children's education, serious illness or disability or other similar
         needs, the Company will consider the continuance of future loans upon
         application by the employee. This application should be made in the
         form of a letter to the President of Elcor requesting that the 75
         percent maintenance requirement be waived, stating the number of shares
         by which holdings will fall below 75 percent and the reason for the
         request. All waivers of the 75 percent requirement must be approved by
         Elcor's President.

Q        ONCE A LOAN IS MADE, WHEN MUST THE STOCK BE PURCHASED?

A.       Participants are responsible to apply the proceeds to purchases of
         Elcor stock. The timing may vary and may be before or after receipt of
         the loan. If an individual, after becoming a Participant, has
         previously purchased Elcor Stock with his or her own funds (and still
         owns the Stock), then such prior purchases could satisfy all or part of
         the requirements. Evidence of all purchases must be furnished to
         Elcor's Controller within six months of the disbursement of the loan to
         the Participant.

Q.       WHAT EVIDENCE WILL BE REQUIRED TO SHOW THAT THE STOCK WAS
         PURCHASED?

A.       When Stock is purchased from a broker, the broker furnishes the buyer a
         "confirmation" which is a document showing the number of shares
         purchased, price, trade date and settlement date. A copy of this
         document will be required by the Company. If the Stock is acquired
         under the Elcor Stock Purchase Plan, no additional evidence is
         required.

Q.       CAN STOCK BE PURCHASED IN "STREET NAME", I.E., WHERE THE RECORD OWNER
         OF THE STOCK IS THE BROKER RATHER THAN THE PURCHASER?

A.       Yes, provided that, if carried in "street name" the Participant
         signifies in advance his or her intention to do so and furnishes at
         least quarterly to Elcor's Controller a copy of the monthly 

                                      -8-
<PAGE>   9

         statement from a brokerage firm. Additionally, if the Stock is
         purchased by ChaseMellon Shareholder Services for a Participant under
         the Elcor Stock Purchase Plan, the Participant may hold the Stock under
         ChaseMellon's name.

Q.       WILL COMMISSIONS, BROKER FEES AND TRANSFER FEES COUNT AS PART OF
         THE COST OF STOCK?

A.       Yes.

Q.       CAN STOCK BE PURCHASED JOINTLY WITH EMPLOYEE'S SPOUSE?

A.       Yes, as long as the employee is shown on the Stock certificate or
         brokerage statement as one of the owners.

Q.       CAN STOCK BE PURCHASED OTHER THAN THROUGH A BROKER?

A.       Yes. However, in these instances, the Company should be contacted to
         determine what procedures should be followed to provide written support
         of the purchase. Also, such Stock may be "Restricted" Stock with
         limitations on its resale. The Stock can also be purchased through
         ChaseMellon Shareholder Services under the Elcor Stock Purchase Plan.

Q.       IF AN EMPLOYEE IS ELIGIBLE TO OBTAIN A LOAN EACH QUARTER, IS HE OR
         SHE REQUIRED TO OBTAIN THE LOAN AND PURCHASE STOCK EACH
         QUARTER?

A.       No. The Company recognizes that there may be times where the
         Participant may wish to defer the purchase of Stock to a later date,
         for instance if the amount of available loan is small. Each Loan Right
         has an expiration date one year after the date notice of Loan Rights is
         given to the employee.

Q.       ARE THERE ANY FEDERAL INCOME TAX CONSIDERATIONS ON THE LOAN?

A.       Yes. There are federal (and state and local, where applicable) income
         taxes and withholding obligations payable when the Company forgives the
         repayment of principal or interest upon the loan. If the employee had
         obtained four loans in a year (one each quarter), 20 percent of each
         loan, along with forgiven accrued interest on the entire outstanding
         balance of the loan then outstanding, would be taxable in each of the
         next five years if the employee remains employed by Elcor or a
         subsidiary.

Q.       HOW WILL THESE TAXES BE PAID?


                                      - 9 -

<PAGE>   10


A.       The Company will include this income in the employee's Form W-2 at each
         year end and in the employee's gross earnings (with applicable tax
         withholdings) during the year as loans are forgiven.

Q.       WHAT TAXES ARE PAYABLE ON SALE OF THE STOCK?

A.       Any gain on each sale is taxable as a short-term or long-term gain, as
         the case may be. The gain portion is generally the total sale proceeds,
         net of any brokerage commissions, fees and transfer taxes, less the
         employee's tax basis in the Stock (what the employee paid for the
         Stock, including commissions, brokerage fees and transfer taxes). The
         fact that the employee borrowed the money to purchase the Stock has no
         bearing on his or her tax basis in the Stock for this purpose.

Q.       HOW IS THE LOAN OBTAINED?

A.       Each quarter, Elcor's President will send a Loan Rights letter and
         Promissory Note to each employee eligible to obtain a loan that
         quarter. This letter will include the amount of the Loan obtainable,
         the period of time during which the loan can be obtained, and certain
         conditions with which the employee must comply to receive a Stock/Loan.
         If the employee wishes to obtain a loan, the Promissory Note
         accompanying the Loan Rights letter should be signed, dated and
         returned to Elcor's Controller. Upon receipt of the Promissory Note,
         the Controller will cause Elcor to issue a check to the Participant, or
         to send funds to ChaseMellon Shareholder Services for the Elcor Stock
         Purchase Plan, as the Participant directs.

Q.       CAN A PARTICIPANT BUY MORE STOCK THAN THE AMOUNT OF THE LOAN?

A.       Obviously, yes. This Plan is to assist Participants in acquiring Elcor
         Stock but does not limit the amount of Stock that can be acquired with
         the employee's own funds.

Q.       IS THERE ANY RISK TO PARTICIPATING IN THE PLAN?

A.       Yes. The value of the Stock purchased with a loan could decline after
         purchase below the amount of the loan. If you lose your employment for
         reasons other than normal retirement, death or disability, you will be
         required to immediately repay all outstanding loan amounts with
         interest. To maintain the integrity of the Plan, the Company may sue
         for any failure to promptly pay such amounts.

                    LETTER RE: CHANGE IN ACCOUNTING PRINCIPLE
     
  August 18, 1998    

  Elcor Corporation
  14643 Dallas Parkway, Suite 1000
  Dallas, Texas  75240-8871



  Re:  Form 10-K Report for the year ended June 30, 1998

  Gentlemen:

  This letter is written to meet requirements of Regulation S-K calling for
  a letter from a registrant's independent accountants whenever there has been a
  change in accounting principle or practice.

  As of June 30, 1998, the company changed from the last-in, first-out
  method of accounting for inventories to the first-in, first-out method.
  According to the management of the company, this change was made to provide a
  better measurement of operating results.

  A complete coordinated set of financial and reporting standards for
  determining the preferability of accounting principles among acceptable
  alternative principles has not been established by the accounting profession.
  Thus, we cannot make an objective determination of whether the change in
  accounting described in the preceding paragraph is to a preferable method.
  However, we have reviewed the pertinent factors, including those related to
  financial reporting, in this particular case on a subjective basis, and our
  opinion stated below is based on our determination made in this manner.

  We are of the opinion that the company's change in method of accounting is
  to an acceptable alternative method of accounting, which, based upon the
  reasons stated for the change and our discussions with you, is also preferable
  under the circumstances in this particular case. In arriving at this opinion,
  we have relied on the business judgment and business planning of your
  management.

  Very truly yours,
