ITEM 1. BUSINESS.
 
GENERAL
 
     Southdown, Inc. was organized in Louisiana in 1930 and maintains its
principal executive offices at 1200 Smith Street, Suite 2400, Houston, Texas
77002-4486, telephone (713) 650-6200. The Company reorganized its corporate
structure at the end of 1998 to merge most of its recently acquired Medusa
entities with and into Southdown and contribute the Company's California cement,
concrete products and aggregates operations to certain existing and newly
created wholly-owned subsidiaries of the Company. The terms "Southdown" and the
"Company" as used in this report, include subsidiaries of Southdown and also
predecessor corporations.
 
     On June 30, 1998, the Company concluded a merger transaction with Medusa
Corporation. Medusa became a 100% owned subsidiary of the Company at that time.
The Medusa merger converted each outstanding Medusa common share into the right
to receive .88 shares of Company common stock. The Company issued approximately
14.7 million shares of its common stock for all of the outstanding common stock
of Medusa. The Medusa merger also converted Medusa's outstanding employee stock
options the same way, so these Medusa options became options to purchase
approximately 522,000 shares of Company common stock. The exchange of Medusa
shares and options for Company shares and options was tax-free. The transaction
was treated as a "pooling of interests" rather than a purchase of one company by
another. A pooling of interests accounts for a business combination as the
uniting of the ownership interests of companies by an exchange of stock. All
prior period consolidated financial statements presented provide the combined
results of operations, financial position and cash flows of the Company and
Medusa.
 
     The Company operates in three business segments. Southdown is one of the
largest producers of cement in the U.S. The Company operates twelve portland
cement manufacturing plants located in Alabama, California, Colorado, Florida,
Georgia, Kentucky, Michigan, Ohio, Pennsylvania, Tennessee and Texas, plus an
extensive network of cement distribution terminals. The Company also mines,
processes, and sells construction aggregates and specialty mineral products in
the eastern half of the U.S. and in California and operates a subsidiary that
installs highway safety systems such as guardrails, traffic signals, highway
signage and lighting. In addition, the Company markets ready-mixed concrete
products in two of its largest cement markets, California and Florida.
 
COMPANY OPERATIONS
 
     Information concerning the Company's net sales, operating profit, assets
employed and additional information attributable to each business segment for
each year in the three year period ended December 31, 1998 is included in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" on pages 65 through 74 and in Note 4 of Notes to Consolidated
Financial Statements on pages 41 through 43 of the Company's 1998 Annual Report
to Shareholders, which information is incorporated by reference.
 
  CEMENT SEGMENT
 
     Cement is the basic binding agent for concrete, a primary construction
material. The Company's cement products are produced primarily from raw
materials found at or near the Company's plant locations. Depending upon the
process at individual plants, production of one ton of finished product consumes
approximately 1.7 tons of raw material. The principal raw material used in the
production of portland cement is calcium carbonate found in the form of
limestone. The Company's total estimated recoverable reserves of limestone are
approximately 988 million tons located on approximately 26,000 acres, most of
which are owned by the Company in fee. Other raw materials, used in
substantially smaller portions than limestone, include sand, iron ore or other
iron bearing materials, clay and gypsum. When not found in adequate amounts in
the Company's quarries, these materials are purchased from outside suppliers.
 
                                        3
<PAGE>   4
 
     The manufacture of portland cement primarily involves the crushing,
grinding and blending of limestone and other raw materials into a chemically
proportioned mixture which is then processed in a rotary kiln at extremely high
temperatures to produce an intermediate product known as clinker. The clinker is
cooled and interground with a small amount of gypsum to produce finished cement.
As fuel is a major component in the cost of producing clinker, the
pyroprocessing systems of most modern cement plants incorporate some form of the
more fuel efficient "dry process" technology. In preheater/precalciner kilns,
the most modern application of this technology, the raw materials are initially
introduced into a preheater tower that utilizes hot exhaust gases from the kiln
to effect partial calcination of the raw materials before they enter the rotary
kiln. At present, eleven of the twelve plants operated by the Company,
representing approximately 96% of the Company's clinker capacity, utilize some
variation of the dry process manufacturing technology. In contrast, based on
1997 data, the most current information available, the Portland Cement
Association estimates that approximately 73% of the domestic cement industry's
capacity utilizes dry process technology.
 
     Demand for cement is derived from the demand for concrete products which,
in turn, is dependent on the demand for construction. According to estimates of
the Portland Cement Association, the industry's primary trade organization, the
three construction sectors that are the major components of cement consumption
are (1) public works construction, including public buildings, (2) commercial
and industrial construction, and (3) residential construction. Public works
construction, which includes public buildings and infrastructure projects,
comprised 54% of U.S. cement consumption in 1997, the most recent period for
which such data is available. The U.S. Congress passed legislation in 1998 known
as the Transportation Equity Act for the 21st Century. This legislation
authorized $218 billion in federal expenditures on highways, bridges and mass
transit projects over the next six years. This represents a 44% increase over
the previous six-year period, which ended in 1997.
 
     Commercial and industrial construction comprised 18% of U.S. cement
consumption in 1997, while residential construction comprised 22% and other
miscellaneous usage comprised 6%. Construction spending and cement consumption
has historically fluctuated widely. The construction sector, and hence demand
for cement and concrete, is affected by the general condition of the economy and
prevailing interest rates, and can exhibit substantial variations in activity
across the country as a result of the differing cycles and structures of
regional economies. The impact on the Company of regional construction cycles
may be mitigated to some degree by its geographic diversification. Because of
the high fixed-cost nature of the business, however, the overall profitability
of cement manufacturers, including the Company, is sensitive to variations in
sales volumes and shifts in the balance between supply and demand. The Company's
business is seasonal to the extent that construction activity tends to diminish
during the winter months in many areas of the country and during other periods
of inclement weather.
 
     The Company's cement production facilities are located principally in the
eastern half of the U.S. and in certain key southwestern states. These plants
have a combined cement manufacturing capacity of approximately 11.2 million tons
(10.8 million tons, excluding the joint venture interests of others). All of the
facilities are wholly owned except for the Kentucky plant and the smaller plant
in Pennsylvania. These two plants are owned by Kosmos Cement Company, a joint
venture owned 75% by the Company and 25% by Lone Star Industries, Inc. The
Company is the operator of all twelve plants, including the two joint venture
plants.

(1) Owned by Kosmos Cement. The Company owns 75% of the joint venture and
    operates the joint venture's plants, sales offices and terminals.
 
(2) The Company has a long-term supply agreement with an independent third party
    to provide limestone for this plant.
 
     As a result of continued high uptime and demand, the ratio of actual
clinker production to rated kiln capacity was approximately 98% in each of the
three years ended 1998. During each of the past three years, the Company has
also purchased cement from others for resale. In 1998, 4.8% of the cement sold
by the Company was acquired from third parties compared with 5.1% in 1997 and
4.1% in 1996.
 
     During 1998, the Company sold approximately 11.4 million tons of cement
compared with 11.1 million tons in 1997 and 10.6 million tons in 1996. Sales
volumes attributable to the joint venture interests of others were approximately
300,000 tons in each of the three years 1998, 1997 and 1996. High levels of
construction activity in most regions of the country during the last several
years has resulted in a more favorable balance in the supply and demand for
cement which, in turn, has allowed sales prices to rise. During 1998, the
industry continued to benefit from demand growth and higher sales prices. As a
consequence of these improvements in market conditions, the Company's Cement
segment revenues and earnings have followed a pattern of continued growth since
1991.
 
     Continued strength in all three construction sectors in 1998 resulted in
the fifth consecutive year of record setting cement consumption in the U.S. The
Portland Cement Association has estimated that total U.S. cement plant capacity
utilization was 96% for 1997, the most recent data available. Even at this high
rate of capacity utilization, the cement industry was required to rely on
readily available foreign cement imports to supplement domestic consumption. The
Portland Cement Association has estimated 1997 U.S. clinker production capacity
at 84 million tons (equivalent to approximately 89 million tons of cement
production capacity) while domestic cement consumption was estimated at 106
million tons. Several years of demand-supply relationships favorable to cement
producers have resulted in increasing cement prices to a level where
 
                                        5
<PAGE>   6
 
the domestic cement industry has undertaken the capital investment necessary to
expand production capability.
 
     The Portland Cement Association reports that, as of February 1999,
approximately 30 plant modernizations and expansion projects, including four new
cement plants, have been announced or are underway. These projects, if
completed, could add almost 18-20 million tons of new domestic cement
manufacturing capacity and increase existing capacity by 25%. The announced
expansions represent a significant change for the industry, but market forces
and other factors may intervene on plans and the Company does not anticipate
that all of the industry's announced expansions will actually be constructed.
Also, because of the long lead times associated with adding additional capacity,
any increased production capability is expected to be gradual over the next
several years. The Portland Cement Association has predicted U.S. cement use
will grow to 120.4 million tons by 2003, compared with an estimated 113.8
million tons of cement consumption in 1998. The Company, however, can offer no
guarantee regarding this predicted increase in near-term demand. In addition,
the Company does not know how much, if any, old, inefficient cement production
capacity may be retired during this period.
 
     Business Strategy -- To enhance profitability and return on investment, the
Company intends to continue to focus on its core business through internal and
external growth opportunities, improving productivity and enhancing the
Company's market position. The Company plans to continue to take advantage of
opportunities for internal growth by modernizing and expanding certain of its
existing cement plants through innovation, incorporation of latest generation
process equipment and operational improvements. The Company has announced or
undertaken various capital projects to enhance the productivity and
incrementally expand the capacity of existing cement manufacturing facilities.
The table below compares the Company's annual cement capacity at the end of 1996
with the end of 1998 and pro forma at the end of announced expansions, assuming
completion of all Board approved and in-progress projects. Comparisons are based
on clinker capacity converted to cement at each plant's product mix.

Source: Portland Cement Association. Clinker capacity for joint venture
        operations is based on each company's ownership interest. In general,
        one ton of clinker will produce approximately 1.05 tons of cement,
        although this conversion varies depending on the type of cement being
        produced and other factors.
 
     The cost of transporting cement is high relative to the value of the
product and, therefore, cement markets are generally regional. The market served
by a cement plant may be extended through the use of distribution terminals to
which cement is transferred in bulk and inventoried for sale to customers in
surrounding areas. The majority of the Company's cement sales are made directly
to users of portland and masonry cements, generally within a radius of
approximately 200 miles of each plant. However, access to water transport, which
is less expensive than truck or rail shipment, can effectively expand the market
area of a particular production facility.
 
     The Company's Charlevoix, Michigan Great Lakes shipping location and
water-based terminals in Chicago, Illinois, Cleveland and Toledo, Ohio, Detroit
and Ferrysburg, Michigan, Manitowoc and Milwaukee, Wisconsin and Owen Sound,
Ontario enable about 90% of cement produced at the plant to be shipped by water.
The Company's Demopolis, Alabama plant serves river-based terminals in Nashville
and Chattanooga, Tennessee and in Decatur, Alabama. The Kosmosdale, Kentucky
cement plant serves river-based terminals in Cincinnati, Ohio and Huntington,
West Virginia. The Company's Pittsburgh, Pennsylvania cement plant serves a
river-based terminal in Charleston, West Virginia. The Company also operates
deepwater terminals in Riviera Beach and Tampa, Florida and in Castle Hayne and
Wilmington, North Carolina.

     Cement is a homogeneous commodity that is manufactured to meet standardized
technical specifications and is marketed primarily in bulk quantities without
special packaging or labeling. The Company's bagged cement products have
historically represented approximately 4 to 5% of the Company's total sales
volume. Although previously marketed under regional brand names, bagged cement
products are also marketed under the "Southdown" label beginning in 1999. The
Company also manufactures limited amounts of premium priced, specialty cement
products. Because of the commodity nature of the product, competition among
suppliers of cement is based primarily on price, with consistency of quality and
service to customers being of lesser significance. The overall demand for cement
is relatively price inelastic, however, since cement represents only a small
portion of total construction costs and cement has few substitutes in many
applications.

     The primary purchasers of cement in each of the Company's regional markets
are ready-mixed concrete companies. Except with respect to certain major
construction projects, it is not common in the industry to enter into long-term
sales contracts. From time-to-time, the Company has entered into annual sales
contracts with other cement manufacturers or distributors, but no one customer
represents 10% or more of the Company's consolidated revenues. Because long-term
contracts generally comprise only a small portion of total sales, the Company
does not believe that the concept of "backlog" is relevant for an understanding
of the cement industry.
 
     As a result of the Company's vertical integration, approximately 36% in
1998 and, in both 1997 and 1996, 38% of the cement sold by the Company's
Brooksville, Florida plant was sold to the Company's Florida ready-mixed
concrete products operations. Approximately 17%, 19% and 18%, respectively, of
the cement sold by the Company's California plant in 1998, 1997 and 1996 was
sold to the Company's California ready-mixed concrete operations. Other
principal customers are manufacturers of concrete products such as blocks, roof
tiles, pipes and prefabricated building components. Sales are also made to
building materials dealers, other cement manufacturers, highway and other public
works project construction contractors and, in some regions, oil well cementing
companies. Approximately 43% in 1998 and, in both 1997 and 1996, 58% of the
Company's Texas plant's cement sales volume consisted of sales to oil well
cementing companies.
 
     The Company's sales efforts are concentrated in its 13 sales offices. In
addition, the Company utilizes a network of cement distribution terminals, which
serves to broaden the Company's marketing area. These cement distribution
terminals and sales offices are located as follows:

     Import Competition - During the 1980s there was a surge of unfairly priced
cement and clinker imports into the U.S. In response, U.S. industry
participants, including the Company, filed antidumping petitions in 1989 against
imports from Mexico and, in following years, against imports from Japan and
Venezuela. After investigations into the matter, the International Trade
Commission and the Department of Commerce decided in favor of the petitioners
and issued an antidumping order against Mexican cement and clinker in 1990 and
against Japanese cement and clinker in 1991. In addition, in February 1992,
Commerce suspended investigations of dumped and subsidized imports of cement and
clinker from Venezuela, based upon the Venezuelan cement producers' agreement to
change their prices to stop the dumping of gray portland cement and clinker from
Venezuela into the U.S. and the Venezuelan government's agreement not to
subsidize the Venezuelan cement producers.
 
     As a result of legislation passed by the U.S. Congress in 1994, Commerce
and the International Trade Commission will conduct "sunset" reviews of the
antidumping orders and suspension agreements beginning in August 1999 to
determine whether they should be revoked or remain in effect for another five
years. The Company expects the sunset review process to take longer than a year
and believes there are strong arguments and evidence to convince Commerce and
the International Trade Commission to leave the antidumping remedies in effect.
In addition to the sunset reviews, decisions by Commerce, by North American Free
Trade Agreement binational panels or by the U.S. Courts on appeal of Commerce's
decisions in future administrative reviews could meaningfully reduce the
existing antidumping duties. If any of these events were to happen, there could
be a negative impact on the Company's results of operations.
 
     U.S. imports of foreign cement began to increase in the mid-1990's as the
use of cement in the U.S. began to recover. The Portland Cement Association has
estimated that imports represented approximately 22% of cement used in the U.S.
during 1998 as compared with approximately 18% in 1997 and 16% in 1996. Unlike
the imports during the 1980's, however, most of the recent imports have provided
an additional source of supply rather than disrupting the market with unfair
prices. During most of the recent period of strong demand, the prices of cement
imports rose. The increase was attributable, at least in part, to the influence
of the outstanding antidumping orders and suspension agreements. While the
average cost of imported cement rose during 1998, the cost of cement imports
from some countries, particularly those from Southeast Asia, have declined.
Moreover, independently owned cement operators could undertake to construct new
import facilities and begin to purchase large quantities of low-priced cement
from countries not yet subject to antidumping orders, such as those in Asia,
which could compete with domestic producers. The introduction of low-priced
imported cement from such sources could have a negative impact on the Company's
results of operations.
 
     In addition to receiving imported cement into its river based terminal
network, the Company owns or leases a total of four deepwater cement terminals
in locations capable of receiving imported cement directly. To supplement its
production capacity, the Company sought to meet excess demand with limited
purchases of imported cement beginning in 1994 and has increased purchases of
imported cement in each of the subsequent years, pending the Company's ongoing
investments to modernize and expand production capacity. The resumption of
dumping of low-priced imports on a large scale could have an adverse impact on
such pending investments.
 
  AGGREGATES SEGMENT
 
     The Aggregates segment includes mining, processing, packaging and selling
construction and specialty aggregates and also fabricating and installing
highway safety systems. Numerous aggregates acquisitions by Medusa in 1997 and
early 1998 and the merger of Medusa and Southdown in mid 1998 greatly expanded
the Company's market presence in this business.
 
     Construction Aggregates -- These operations mine, crush, screen, wash and
sell various sizes of aggregates to the construction industry, primarily for use
in the manufacture of asphalt and concrete, as well as in such construction
applications as road base, drainage blankets, erosion control and other
applications. The Company estimates its annual capacity at about 11 million
tons. Construction aggregates are marketed as commodities and as such pricing is
the principal method of competition. Most aggregates are sold within a
 
                                       10
<PAGE>   11
 
35 mile radius of the plant and are shipped to the customer by truck. The
Company's construction aggregates business has approximately 3,000 customers.
The Company believes that it is among the low-cost producers in its primary
markets. The Company maintains its low-cost position through continuous plant
and quarry efficiency improvement programs.
 
     Specialty aggregates -- Specialty aggregates operations include two types
of minerals products: (a) industrial limestone products and (b) lawn and garden
products. For industrial limestone products, white, high calcium limestone is
sold for use in the manufacture of white cement, as a calcium supplement for
livestock and poultry feeds, to treat acidic water conditions, to neutralize
acidic soil for more efficient crop yields, and to scrub sulfur emissions in
coal burning generating plants. The white limestone is also pulverized to a fine
powder and used to produce joint and caulking compounds, carpet backing, vinyl
floor tile, paints, plastics, and PVC pipe. Buff colored limestone is pulverized
and marketed for use in the production of asphalt shingles and other roofing
products.
 
     Commercial markets such as golf courses, lawn care, grounds maintenance,
water conditioning, and agriculture are served with over 200 specialty mineral
products. Lawn and garden operations mine, process, package and distribute to
both consumer and commercial markets throughout the eastern half of the U.S.
Over 150 products for lawn care, gardening, landscaping and do-it-yourself
construction are shipped directly to over 3,500 retail garden centers and home
improvement outlets. Lawn and garden products are marketed under both the
Southdown(R) and Yardright(R) brand names. Limestone is applied to lawns and
agricultural fields to correct soil acidity, primarily in states east of the
Mississippi River, where high soil acidity is a problem. The Company believes it
has approximately a 35-40% share of the pelletized limestone market it serves.
The Company estimates that its three pelletizing operations have combined annual
capacity of over 200,000 tons. In addition to pelleted limestone and other
related liming products, other core products include pelleted gypsum, white
marble chips, natural colored landscaping stone, play sands, packaged concrete
and hydrated lime.
 
     Aggregates Reserves -- Plant by plant, and at current construction
aggregates production levels, 95% of the Company's various aggregates reserves
will last from at least 10 years to over 50 years. At current production levels,
almost 100% of the Company's various mineral reserves will last from 30 years to
over 100 years. The following table indicates the location of the Company's
construction and specialty aggregates operations:

     Competition in the Aggregates segment includes numerous small and several
large aggregate quarry operators. Competition for sales volume is strong and is
based primarily on price with consistency of quality and service to customers
being of importance, but somewhat lesser significance. The Company's major
competitors are Global Stone, Georgia Marble, J.M. Huber and English China Clay
in specialty aggregates, and Hanson Boone Quarries, Vulcan Materials Company,
Martin Marietta Materials, Inc., Sterling Ventures, and East Fairfield Coal in
the construction aggregates market.

     Highway Safety Construction -- Through the James H. Drew Corporation, a
wholly-owned subsidiary of the Company based in Indianapolis, Indiana, the
Aggregates segment also operates generally in the mid-western states installing
highway safety systems such as guardrails, traffic signals, signs, and highway
lighting. Although Drew functions primarily as a subcontractor to paving and
bridge contractors, approximately 30% of its work is bid directly to state
highway departments and municipalities.
 
  CONCRETE PRODUCTS SEGMENT
 
     Ready-mixed concrete is a versatile, low-cost building material used in
almost all construction applications. Concrete is produced in batch plants by
mixing stone, sand, water and chemical admixtures with cement, the basic binding
agent, and is transported to the customer's job site in mixer trucks. The
Company has vertically integrated its operations in the regional vicinity of its
two largest cement plants, which are located in Florida and in California.
During the last three years, the Florida concrete products operations have
consumed approximately 38% of the cement sold by the Company's Florida cement
plant, while the California concrete products operations have purchased between
17% and 19% of the cement sold by the Company's California cement plant. The
Company believes that this vertical integration into ready-mixed concrete and
concrete products operations enhances its overall competitive position in these
markets, where most cement producers are vertically integrated.
 
     The Company, doing business in both California and in Florida as Southdown
Concrete Products, Inc., is a producer of ready-mixed concrete in each area. The
California operation sells primarily to commercial and industrial builders, as
well as contractors on public construction projects. Southdown Concrete Products
in Florida is a major producer and supplier of ready-mixed concrete and concrete
masonry. Florida sales include a high percentage of sales to residential
builders.
 
     The Company's Concrete Products segment operates a combined total of
approximately 550 ready-mixed concrete trucks, approximately 66 batch plants and
9 concrete block plants. The Company's estimate of its combined annual practical
capacity as of December 31, 1998 is in excess of 4.5 million cubic yards. The
Company's concrete products operations in California and Florida each purchase
most of their cement from the Company's cement plants in California and Florida,
respectively. The California concrete products operations extract their sand and
gravel primarily from the two California aggregate quarries. The Company
currently purchases sand and gravel for use in its Florida ready-mixed concrete
operations under a long-term aggregate supply contract. Alternative supplies of
cement and aggregate are readily available from other sources, if necessary.
 
  Market Conditions
 
     The demand for concrete products is derived from the demand for
construction. The construction sector is subject to the vagaries of weather
conditions, the availability of financing at reasonable interest rates and
cyclical fluctuations in regional economies. The burden of relatively high fixed
costs results in a disproportionate impact on profits from only minor variations
in sales volume. Seasonal factors are not as significant in the market areas
served by the Company's concrete products businesses as in some markets, but
construction activity tends to diminish during prolonged periods of inclement
weather. In 1998, Company sales volumes were 3.6 million cubic yards of
ready-mixed concrete. Ready-mixed concrete sales volumes totaled approximately
3.7 million cubic yards in both 1997 and 1996.
 
     Competition within each market includes numerous small and several large
ready-mixed concrete operators. Competition for sales volume is strong, and is
based primarily on price, with consistency of quality and service to customers
being of lesser significance. In Florida, the Company's principal competitors
include Tarmac Florida, Inc., Rinker Materials Corp. and Florida Rock
Industries, Inc. In California, the Company's principal competitors include
United Ready-Mixed Concrete Co. Inc., A&A Ready-Mixed Concrete, Inc.,
Robertson's Ready Mix, Inc. and Catalina Pacific Concrete, Inc.

  ENVIRONMENTAL MATTERS
 
     The Company is subject to a wide range of federal, state and local laws,
regulations and ordinances dealing with the protection of human health and the
environment. These laws regulate water discharges and air emissions, as well as
the handling, use and disposal of hazardous and non-hazardous waste materials.
These laws also create a shared liability by responsible parties for the cost of
cleaning up or correcting releases to the environment of designated hazardous
substances. The Company or its predecessors have conducted industrial operations
at the Company's cement manufacturing facilities for many years. As was common
in the industry, the Company in the past disposed of various materials used in
its cement manufacturing and concrete products operations in onsite and offsite
facilities. Today, some of these materials may be classified as hazardous
substances. The Company, therefore, may have to remove or mitigate the
environmental effects of the disposal or release of certain substances at the
Company's various operating facilities or elsewhere.
 
     Several of the Company's previously and currently owned facilities have
become the subject of various local, state or federal environmental proceedings
and inquiries. While some of these matters have been settled, others are in
their preliminary stages and may not be resolved for years. The information
developed to date on these matters is not complete. Based on what it knows
currently, however, the Company does not believe it will be required to spend
significantly more on these matters than the amounts already recorded in the
Company's financial statements. However, until all (1) environmental studies and
investigations, (2) remediation work, (3) negotiations with other parties that
may be responsible, or (4) litigation against other potential sources of
recovery have been completed, it is impossible to determine the ultimate cost
that the Company might incur to resolve these environmental matters.
 
     Cement Kiln Dust -- Cement manufacturing plants, depending on their process
design, raw materials characteristics, product specifications and other factors,
may generate a low toxicity by-product known as cement kiln dust or CKD. Most
manufacturing plants in the industry typically disposed of CKD in and around
their plant sites since the inception of cement manufacturing operations. CKD is
currently not regulated as a hazardous waste. The U.S. Environmental Protection
Agency decided in 1995 that some further regulation of CKD was necessary. At the
same time, the U.S. EPA stated that it (1) found no evidence of risks associated
with the use of cement products and (2) believes most secondary uses of CKD do
not present significant risks to people or the environment. The U.S. EPA began a
rulemaking process in order to develop specially tailored CKD management
standards. The Company expects the U.S. EPA to propose new CKD standards by the
end of 1999. Once finalized, these new CKD standards may require the cement
industry to implement new management practices for this waste material.
 
     If CKD becomes saturated with water, liquid that leaches out may have an
alkalinity level high enough to be classified as hazardous. Saturated CKD may
also leach out certain hazardous trace metals if they are present. Discharges of
pollutants have been alleged from two CKD sites in the vicinity of the Company's
Ohio cement plant and one site in the vicinity of its recently acquired Medusa
cement plant in Michigan. For one of the Ohio sites, the Company has previously
recorded remediation charges totaling approximately $13 million where leaching
occurred. The Company is involved in a lawsuit with a private party over the
other Ohio site, but the Company believes it has no liability in the matter
since the Company no longer owns the property and, therefore, should have no
ongoing obligation to obtain a permit for the alleged discharge from the site,
the sole allegation in the lawsuit.
 
     The Company is investigating potential contamination from a total of nine
separate CKD piles at its cement plant in Michigan. The Company is also working
with a consultant and the Michigan Department of Environmental Quality to
develop a new on-site CKD landfill. During 1997, Medusa proposed building a new
landfill on top of one of the identified CKD piles. The new $2 million landfill
is expected to remedy the problems with three existing CKD piles, because the
new landfill will serve to cap one of the existing CKD piles and two others will
be relocated into the new landfill. The new landfill, as permitted, would also
be large enough for the disposal of CKD generated in the future for the next 30
years. The Michigan Department of Environmental Quality gave final approval for
construction of this landfill in April 1998.
 
     The Company's Michigan cement plant has also submitted plans to the
Michigan Department of Environmental Quality concerning the remediation of the
other six identified CKD piles. These plans are
                                       13
<PAGE>   14
 
currently under review by the Michigan Department of Environmental Quality. The
Company estimates total costs associated with these plans are in the range of $5
million to $9 million. In the fourth quarter of 1997, Medusa accrued $3.6
million related to various non-capital costs associated with the nine CKD piles.
As a result of further investigation, the Company accrued an additional $1.6
million in CKD remediation costs in June 1998, based on the most current
information available. The Company does not know when or if the various
remediation proposals will be approved by the Michigan Department of
Environmental Quality. At the present time, the Company does not know the
ultimate cost to resolve these issues or over what period the Company will incur
these costs.
 
     The California Regional Water Quality Control Board required the Company to
investigate the status of two CKD disposal sites at the Company's California
cement plant. The initial phase of the investigation showed no deleterious
impacts to groundwater at one site, but the Company is continuing to monitor the
groundwater at this site. The Company believes there is little likelihood of
groundwater impacts at the second California site because of the great depth to
groundwater aquifers.
 
     The Georgia EPA has required the Company's Clinchfield, Georgia cement
plant to investigate potential groundwater impacts from a landfill at the plant.
Although groundwater monitoring at this plant is in its initial phase, the
results to date do not indicate there were releases from the landfill.
 
     The Company owns a total of approximately 40 CKD disposal sites. The
Company has not had reason to conduct meaningful investigation at any of its
other CKD disposal sites.
 
     Clean Air Act -- Regulations issued under the Clean Air Act Amendments of
1990 May result in increased capital and operational expenses for the Company in
the future. The Company does not know how much of an increase that might be. In
addition, the U.S. EPA is developing air toxics regulations for a broad range of
industrial sectors, including portland cement manufacturing. If enacted, these
new standards would apply to everyone in the industry. However, because of the
age, condition and design of its plants, management believes the Company would
not be at a disadvantage with respect to its competitors.
 
     In July 1997, the U.S. EPA promulgated revisions to two National Ambient
Air Quality Standards under the Clean Air Act -- particulate matter and
photochemical oxidants (ozone). Because of the nature of the Company's
operations, the proposed addition of a particulate matter standard that will
regulate particles 2.5 microns or less in diameter, and the regulation of
nitrogen oxides emissions as the precursor pollutants to ozone, is of potential
concern. Implementation of these new standards will not immediately have an
impact on industrial operations. The first step is a several-year data
collection and analysis activity by the states to determine whether or not the
state will be able to meet the new standards. If a state is unable to
demonstrate that it attains the standards, it will then be required to modify
its air quality implementation plan to describe actions to meet the new
standards. It is presently unknown whether states in which the Company operates
will be able to meet the new standards, how the states will modify their
implementation plans to demonstrate compliance and/or the ultimate technology
and cost impact on the Company's operations.
 
     Another evolving issue of potential significance to the Company is global
warming and the international accord on carbon dioxide stabilization/reduction.
Carbon dioxide is a greenhouse gas many scientists and others believe
contributes to a warming of the Earth's atmosphere. In December 1997, the United
Nations held an international convention in Kyoto, Japan to take further
international action to ensure greenhouse gas stabilization and/or reduction
after the turn of the century. The conference agreed to a protocol to the United
Nations Framework Convention on Climate Change originally adopted in May 1992.
The protocol establishes quantified emission reduction commitments for certain
developed countries, including the U.S., and certain countries that are
undergoing the process of transition to a market economy. These reductions are
to be obtained by 2008-2012. The protocol was made available for signature by
member countries starting in the spring of 1998. The protocol will require
Senate ratification and enactment of implementing legislation before it becomes
effective in the United States.
 
     The consequences of greenhouse gas reduction measures for cement producers
are potentially significant because carbon dioxide is generated from combustion
of fuels such as coal and coke in order to generate the high temperatures
necessary to manufacture cement clinker (which is then ground with gypsum to
make
 
                                       14
<PAGE>   15
 
cement). In addition, carbon dioxide is generated in the calcining of limestone
to make cement clinker. Any imposition of raw material or production limitations
or fuel-use or carbon taxes could have a significant impact on the cement
manufacturing industry. It will not be possible to determine the impact on the
Company until governmental requirements are defined and/or the Company can
determine whether emission offsets and/or credits are obtainable, and whether
alternative cementitious products or alternative fuel can be substituted.
 
     The Company's Wampum, Pennsylvania cement plant has received five Notices
of Violation from the U.S. EPA alleging certain air emission violations. The
U.S. EPA has referred these notices to the U.S. Department of Justice for
potential civil enforcement. Three of the notices allege opacity and fugitive
emissions violations of Pennsylvania law and maintain that the provisions are
enforceable by federal authorities. The two remaining notices allege visible
emissions violations related to the provisions of the plant's state operating
permit for burning waste-derived liquid fuel. These notices also maintain that
the state permit provisions are enforceable by federal authorities.
 
     The parties have negotiated a preliminary agreement in principle subject
also to the negotiation of a mutually agreeable consent decree. The Company
anticipates that the consent decree will include future compliance obligations
and penalty payments. The Company does not expect the penalty payments to
materially exceed the amount the Company has already reserved for this matter.
Discussions are still ongoing, however, and therefore, the Company is unable at
this time to provide assurances as to the ultimate liability that may be
associated with these matters.
 
     Waste-Derived Liquid Fuels -- The Company operates two cement plants
(Wampum, Pennsylvania and Demopolis, Alabama) that historically have used
waste-derived liquid fuels as a supplemental fuel source. The use of
waste-derived liquid fuels is subject to emission limits and other requirements
under the Resource Conservation and Recovery Act and regulations issued under
the Act. The regulations apply to plants operating under "interim status" while
the plants go through the process to get a RCRA permit. The regulations are
extremely complex. The Company is required to test periodically for compliance
with the rules and submit certificates of compliance. The tests are subject to
monitoring and review by the U.S. EPA. The Company believes it is complying with
the regulations. The Company cannot say for certain, however, that the U.S. EPA
or other agencies will always agree with the Company or not require additional
tests or levy fines for non-compliance.
 
     Following the merger with Medusa Corporation, the Company thoroughly
evaluated the use of waste-derived liquid fuel at these two plants and decided
the practice is incompatible with the Company's other cement operations because
it reduces productivity, increases compliance costs, and has the potential to
create other liabilities. The Company has already stopped burning waste-derived
liquid fuel at one of the two plants and intends to stop burning waste-derived
liquid fuel at the second plant in early 1999. Environmental regulations require
plants that have used waste-derived liquid fuel to go through "closure
procedures" once the use of these fuels ceases. The Company anticipates it will
have completed closure requirements at both plants by June 30, 1999. Of the
$82.9 million initial estimate of merger related transaction costs, $2.2 million
represents costs related to exiting this incompatible business activity. The
charge includes the estimated cost of the closure procedure and the writedown of
the Company's assets associated with the waste-derived liquid fuel handling.
 
     In April 1998, the Company entered into a Consent Order with the U.S. EPA
that requires the Company to take samples at six of the seven areas the U.S. EPA
has identified as "solid waste management units" at the Kosmosdale cement plant.
The Consent Order itself does not (1) require remediation, (2) provide a
mechanism for remediation, or (3) require any payment by the Company to the U.S.
EPA. If the Company finds no hazardous constituents of concern at the solid
waste management units or if there does not appear to be a threat to human
health or the environment from such constituents, then the U.S. EPA will provide
a "no further action determination." If hazardous constituents are present at
levels of concern at any of the solid waste management units, the Consent Order
provides a way for the U.S. EPA to require in-depth investigation and an
analysis of whether remediation is necessary at any solid waste management
units. In a similar situation, the Company received notice in February 1999 that
no further action is required at the present time at the twenty-five solid waste
management units at the Company's Knoxville, Tennessee cement plant.
 
                                       15
<PAGE>   16
 
     Concrete Products -- As with the cement operations, the concrete products
operations are presently the subject of extensive local, state or federal
environmental laws and regulations.
 
     Aggregates Acquisitions -- During 1997, Medusa assumed $8.1 million in
estimated environmental liabilities related to three aggregates acquisitions.
Environmental matters related to the acquired properties include (1)
environmental cleanup, (2) containment and compliance matters including waste
lime, coal ash and kiln brick issues, (3) wetland considerations, and (4)
underground and above ground storage tank removal. Although the Company believes
the $8.1 million reserve on its books is adequate to remedy these environmental
problems, it is impossible to know with certainty until all work is complete.
 
     The Company, along with other entities with operations in the San Gabriel
basin in the vicinity of Azusa, California, has received notices of potential
responsibility and requests for information by the U.S. EPA. The Company
presently leases and operates a quarry in the vicinity of Azusa, which the
Company sold, together with a related landfill, to a subsidiary of
Browning-Ferris Industries, Inc. in 1987. Browning-Ferris is contractually
obligated to indemnify the Company for any environmental liability arising from
the Company's prior ownership of the land comprising its current aggregates and
ready-mixed plant and the landfill site. Browning-Ferris is also contractually
obligated to indemnify the Company for any environmental liability arising from
the Company's operation of the Azusa landfill prior to the sale of the property
to Browning-Ferris in 1987. The Company has formally requested that
Browning-Ferris indemnify and defend the Company with respect to these matters,
but is unable to quantify the amount of indemnification being sought.
 
     Recurring Costs of Environmental Compliance -- Management believes that the
Company's current procedures and practices for handling and management of
materials are generally consistent with industry standards and legal
requirements and that appropriate precautions are taken to protect employees and
others from harmful exposure to hazardous materials. However, because of the
complexity of operations and legal requirements, there can be no assurance that
past or future operations will not result in operational errors, violations,
remediation liabilities or claims by employees or others alleging exposure to
toxic or hazardous materials. Owners and operators of industrial facilities may
be subject to fines or other actions imposed by the U.S. EPA and corresponding
state regulatory agencies for violations of laws or regulations relating to
hazardous substances. The Company has incurred fines imposed by various
environmental regulatory agencies in the past.
 
     The Company's compliance with the exacting requirements and varying
interpretations of applicable laws and regulations related to the protection of
human health and the environment requires substantial expenditures and
significant amounts of management time and energy. Although the Company does not
maintain records that segregate such costs from the other costs of on-going
operations, management believes recurring environmental compliance costs are a
material component of total costs. In addition to current period expenses, the
Company typically spends several million dollars a year on capital projects
related to environmental compliance. Approximately $13.6 million, 7% of the
budgeted 1999 capital expenditures, is related to compliance with environmental
regulations.
 
     While the Company commits substantial resources to complying with the laws
and regulations concerning the protection of human health and the environment,
the Company considers this to be an integral part of its business. As a
consequence, management does not believe that environmental compliance
expenditures place the Company at a competitive disadvantage with respect to
other companies engaged in similar lines of business operating in the U.S.
However, because of the complexity and uncertainty of existing and future
environmental requirements, permit conditions, costs of new and existing
technology, potential remedial costs and insurance coverages, and/or
enforcement-related activities and costs, it is difficult for management to
estimate the ultimate level of Company expenditures related to environmental
matters. While amounts accrued and paid in the past have not been material, the
Company's capital expenditures and operational expenses for environmental
matters have increased and are likely to increase in the future. The Company
cannot determine at this time whether capital expenditures and other remedial
action that the Company may be required to undertake to comply with the changing
environmental protection laws will materially affect its capital expenditures or
earnings. With respect to known environmental contingencies, the
 
                                       16
<PAGE>   17
 
Company has recorded provisions for estimated probable liabilities and does not
believe that the ultimate resolution of such matters will have a material effect
on the Consolidated Financial Statements.
 
EMPLOYEES
 
     As of December 31, 1998, the Company employed approximately 3,700 persons,
including approximately 1,750 in the cement manufacturing operations, 1,050 in
the concrete products operations, 750 in the aggregates operations and the
remainder in the corporate office. Approximately 35% of the employees are
represented by collective bargaining units, primarily the International
Brotherhood of Boilermakers. Collective bargaining agreements are in effect at
all the Company's cement plants, except for the non-union facility located in
Florida. Labor agreements with the local union of the United Cement, Lime,
Gypsum and Allied Workers Division (International Brotherhood of Boilermakers,
Iron Ship Builders, Blacksmiths, Forgers and Helpers, AFL-CIO) covering the
hourly workers at the Wampum and Louisville plants and at the Lee plant expire
on April 30, 1999 and May 31, 1999, respectively. Other labor contracts expire
at various dates between March 1, 2000 and May 1, 2004.

     BE IT KNOWN, That on this 4th day of March, 1991,
     BEFORE ME, JoAnn M. Pavlock, a Notary Public, duly commissioned and
qualified in and for the County of Harris, State of Texas, and in the presence
of the witnesses hereinafter named and undersigned:

                          PERSONALLY CAME AND APPEARED:

     CLARENCE C. COMER and WENDELL E. PHILLIPS, II, appearing herein and acting
for Southdown, Inc., (of which Corporation they are, respectively, President
and Secretary), a corporation organized and existing under the laws of the State
of Louisiana, domiciled in the Parish of Orleans, State of Louisiana, organized
by Articles of Incorporation effective April 4, 1930, which Articles, as
amended, were restated pursuant to Restated Articles of Incorporation effective
September 15, 1983, who declared that pursuant to Section 24B(6) and 33A of the
Louisiana Business Corporation Law, Article IIIB of the Restated Articles of
Incorporation of the Corporation, and resolutions of the Board of Directors of
the Corporation adopted at a special meeting of the Board of Directors of the
Corporation held on March 4, 1991, they now appear for the purpose of executing
this act of amendment and putting into authentic form the amendment so adopted
by the Board of Directors of said Corporation.

     AND THE SAID APPEARERS further declare that by vote of the Board of
Directors of said Corporation, it was resolved that Article III of the Restated
Articles of Incorporation of Southdown, Inc. be further amended as follows:

     1. There is added as a new paragraph E of Article III the following:

        E. Of the aforesaid 10,000,000 shares of Preferred Stock, 400,000 shares
shall constitute a separate series of preferred shares designated

<PAGE>   3
"Preferred Stock, Cumulative Junior Participating Series C" (the "Series C
Preferred Stock"). The preferences, limitations and relative rights of the
Series C Preferred Stock are as follows:

                                PREFERRED STOCK,
                    CUMULATIVE JUNIOR PARTICIPATING SERIES C

     1. Dividends. (A) The holders of the Series C Preferred Stock shall be
entitled to receive, when and as declared by the Board of Directors out of the
funds of the Corporation legally available therefor, subject to the prior and
superior rights of the holders of the Corporation's Preferred Stock, $.70
Cumulative Convertible Series A ("Series A Preferred Stock"), the Corporation's
Preferred Stock, $3.75 Convertible Exchangeable Series B ("Series B Preferred
Stock") and any other shares of any series of Preferred Stock ranking senior to
the shares of Series C Preferred Stock as to dividends, but in preference to the
holders of the Common Stock, par value $1.25 per share, of the Corporation (the
"Common Stock") and any other capital stock of the Corporation ranking junior to
the Series C Preferred Stock as to dividends, cumulative preferential dividends
per share of Series C Preferred Stock payable in cash on the last day of March,
June, September and December in each year (each such date being referred to
herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or fraction
of a share of Series C Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to the greater of (a) $2.00 or (b) subject to the provision
for adjustment hereinafter set forth, the Adjustment Number (as defined below)
times the aggregate per share amount of all cash dividends, and the Adjustment
Number times the aggregate per share amount (payable in kind) of all non-cash
dividends or other distributions other than a dividend or distribution payable
in shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series C Preferred Stock. The "Adjustment Number" shall
initially be 100. In the event the Corporation shall at any time after March 4,
1991 (i) declare any dividend on Common Stock payable in shares of Common Stock,
(ii) subdivide the outstanding Common Stock or (iii) combine the outstanding
Common Stock into a smaller number of shares, then in each such case the
Adjustment Number in effect immediately prior to such event shall be adjusted by
multiplying such Adjustment Number by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series C Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Series C Preferred Stock, unless
the date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such 


                                      -2-
<PAGE>   4
shares shall accrue and be cumulative from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after
the record date for the determination of holders of shares of Series C
Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.

     (C) Each dividend on the Series C Preferred Stock shall be paid to the
holders of record of shares of the Series C Preferred Stock as they appear on
the stock register of the Corporation on such record date, not exceeding 30 days
preceding the payment date thereof, as shall be fixed by the Board of Directors
of the Corporation. Dividends on account of arrears for any past dividend
periods may be declared and paid at any time, without reference to any regular
dividend payment date, to holders of record on such date, not exceeding 45 days
preceding the payment date thereof, as may be fixed by the Board of Directors of
the Corporation. No dividend may be declared on any other series or class of
stock ranking on a parity with the Series C Preferred Stock as to dividends in
respect of any dividend period, unless there shall also be or have been declared
on the Series C Preferred Stock like dividends for all periods in the amounts
provided therefor in paragraph 1(A) above. In the event that full cumulative
dividends on the Series C Preferred Stock have not been declared and paid or set
apart for payment, the Corporation may not declare or pay or set apart for
payment any dividends or make any other distributions on, or make any payment on
account of the purchase, redemption or retirement of, the Common Stock or any
other stock of the Corporation ranking junior to the Series C Preferred Stock as
to dividends or distributions of assets on liquidation, dissolution or winding
up of the Corporation (other than, in the case of dividends or distributions,
dividends or distributions paid in shares of Common Stock or such other junior
ranking stock), until full cumulative dividends on the Series C Preferred Stock
are declared and paid or set apart for payment. Further, the Corporation shall
not declare a dividend or distribution on the Common Stock unless it also
declares a dividend or distribution on the Series C Preferred Stock as provided
in paragraph (A) above immediately after it declares a dividend or distribution
on the Common Stock (other than a dividend or distribution payable in shares of
Common Stock); provided that, in the event no dividend or distribution shall
have been declared on the Common Stock during the period between any Quarterly
Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a
dividend of $2.00 per share on the Series C Preferred Stock shall nevertheless
be payable on such subsequent Quarterly Dividend Payment Date.

     2. Redemption (A) The Corporation, at its option, may redeem shares of
Series C Preferred Stock in whole at any time and in part from time to time, at
a redemption price equal to the Adjustment Number times the current per share
market price (as such term is hereinafter defined) of the Common Stock on the
date of the mailing of the notice of redemption, together with accrued and
unpaid dividends to the date of such redemption. The "current per share market
price" on any date shall be deemed to be the average of the closing price per
share of such Common Stock for the ten consecutive Trading Days (as such term


                                      -3-
<PAGE>   5
is hereinafter defined) immediately prior to such date; provided, however, that
in the event that the current per share market price of the Common Stock is
determined during a period following the announcement of (A) a dividend or
distribution on the Common Stock other than a regular quarterly cash dividend or
(B) any subdivision, combination or reclassification of such Common Stock and
the ex-dividend date for such dividend or distribution, or the record date for
such subdivision, combination or reclassification, shall not have occurred prior
to the commencement of such ten Trading Day period, then, and in each such case,
the current per share market price shall be properly adjusted to take into
account ex-dividend or ex-distribution trading. The closing price for each day
shall be the last sales price, regular way, or, in case no such sale takes place
on such day, the average of the closing bid and asked prices, regular way, in
either case as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange, or, if the Common Stock is not listed or admitted to trading on
the New York Stock Exchange, as reported in the principal transaction reporting
system with respect to securities listed on the principal national securities
exchange on which the Common Stock is listed or admitted to trading or, if the
Common Stock is not listed Or admitted to trading on any national securities
exchange, the last quoted sales price or, if not so quoted, the average of the
high bid and low asked prices in the over-the-counter market, as reported by the
National Association of Securities Dealers, Inc. Automated Quotations System or
such other self regulatory organization or registered securities information
processor (as such terms are used under the Securities Exchange Act of 1934, as
amended) that then reports information concerning the Common Stock or, if on any
such date the Common Stock is not quoted by any such entity, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Common Stock selected by the Board of Directors of the
Corporation. If on any such date no such market maker is making a market in the
Common Stock, the fair value of the Common Stock on such date as determined in
good faith by the Board of Directors of the Corporation shall be used. The term
"Trading Day" shall mean a day on which the principal national securities
exchange on which the Common Stock is listed or admitted to trading is open for
the transaction of business or, if the Common Stock is not listed or admitted to
trading on any national securities exchange, a business day.

     (B) In case of the redemption of only part of the Series C Preferred Stock
at the time outstanding, such redemption shall be made pro rata, provided,
however, that the Corporation shall not be required to effect the redemption in
any manner that results in fractional shares being outstanding (unless
immediately prior to such time fractional shares were outstanding, in which case
the Corporation shall not be required to effect the redemption in any manner
that results in fractions of shares, other than one-hundredths of shares, being
outstanding); if full cumulative dividends shall not have been paid or declared
and set apart for payment for all quarterly dividends to and including the last
Quarterly Dividend Payment Date prior to the date fixed for redemption, the
Corporation shall not:


                                      -4-
<PAGE>   6
          (i) call for redemption (except for redemptions in accordance with
     subparagraph 2(B)(iii) below) any shares of Series C Preferred Stock unless
     all such shares then outstanding are called for simultaneous redemption; or

          (ii) redeem or purchase or otherwise acquire (except for redemptions,
     purchases or acquisitions in accordance with subparagraph 2(B)(iii) below)
     for consideration shares of any stock ranking on a parity (either as to
     dividends or upon liquidation, dissolution or winding up) with Series C
     Preferred Stock, provided that the Corporation may at any time redeem,
     purchase or otherwise acquire shares of any such parity stock in exchange
     for shares of any stock of the Corporation ranking junior (both as to
     dividends and upon dissolution, liquidation or winding up) to Series C
     Preferred Stock; or

          (iii) redeem or purchase or otherwise acquire (except for redemptions,
     purchases or acquisitions in accordance with subparagraphs, 2(B)(i) and
     2(B)(ii) above) for consideration any shares of Series C Preferred Stock,
     or any shares of stock ranking on a parity with Series C Preferred Stock,
     except in accordance with a purchase offer made in writing or by
     publication (as determined by the Board of Directors) to all holders of
     such shares of parity stock and Series C Preferred Stock upon such terms as
     the Board of Directors, after consideration of the respective annual
     dividend rates and other relative rights and preferences of the respective
     series and classes, shall determine in good faith will result in fair and
     equitable treatment among the respective series or classes.

     (C) Notice of any proposed redemption of Series C Preferred Stock shall be
given by the Corporation not less than 15 days nor more than 60 days prior to
the date fixed for such redemption to each holder of record of the shares to be
redeemed at his address appearing on the books of the Corporation. Notice of
redemption shall be deemed to have been given when deposited in the United
States mails, by first class mail, whether or not such notice is actually
received. If on or before the redemption date specified in such notice all funds
necessary for such redemption shall have been set aside by the Corporation,
separate and apart from its other funds, in trust for the pro rata benefit of
the holders of the shares so called for redemption, so as to be and continue to
be available therefor, then from and after the date of redemption so designated,
notwithstanding that any certificate representing shares of Series C Preferred
Stock so called for redemption shall not have been surrendered for cancellation,
the shares represented thereby shall no longer be deemed outstanding, the right
to receive dividends thereon shall cease to accrue and all rights with respect
to such shares of Series C Preferred Stock so called for redemption shall
forthwith at the close of business on such redemption date cease and terminate,
except only the right of the holders thereof to receive the redemption price of
such shares so to be redeemed plus an amount equal to accrued and unpaid
dividends (whether or not declared) up to the date fixed for redemption, but
without interest thereon.


                                      -5-
<PAGE>   7
     (D) The Corporation may, however, prior to the redemption date specified in
the notice of redemption, deposit in trust for the account of the holders of the
shares of Series C Preferred Stock to be redeemed, with a bank or trust company
in good standing organized under the laws of the United States of America or of
any state thereof, having its principal office located in the continental United
States, and having a capital, surplus and undivided profits aggregating at least
$50 million, designated in such notice of redemption, all funds necessary for
such redemption (including accrued and unpaid dividends up to the date fixed for
redemption), together with irrevocable written instructions authorizing such
bank or trust company, on behalf and at the expense of the Corporation, to cause
the notice of redemption to be mailed as herein provided at least 15 days but
not more than 60 days prior to the redemption date and to include in said notice
of redemption a statement that all funds necessary for such redemption have been
so deposited in trust and are immediately available, and on the redemption date,
notwithstanding that any certificate representing shares of Series C Preferred
Stock called for redemption shall not have been surrendered for cancellation,
all shares of Series C Preferred Stock with respect to which such deposit shall
have been made and which are outstanding on such redemption date shall no longer
be deemed to be outstanding and all rights with respect to such shares of Series
C Preferred Stock shall forthwith at the close of business on such redemption
date cease and terminate, except only the right of the holders thereof to
receive from such bank or trust company, at any time after the redemption date,
the redemption price of such shares so to be redeemed plus accrued and unpaid
dividends up to the date fixed for redemption.

     (E) If any shares of Series C Preferred Stock called for redemption are not
issued and outstanding as of the date fixed for redemption, the amount set aside
or deposited for the redemption thereof shall revert to or be paid over to the
Corporation.

     (F) Any shares of Series C Preferred Stock which are redeemed or otherwise
purchased or acquired by the Corporation or any subsidiary thereof shall be
cancelled. The number of shares of Series C Preferred Stock shall be reduced by
the number of shares so cancelled and such cancelled shares shall be restored to
the status of authorized but unissued shares of Preferred Stock that are
undesignated as to series. For the purposes of this paragraph, a subsidiary
means a corporation of which a majority of the capital stock having voting power
under ordinary circumstances to elect a majority of the board of directors is
owned by (a) the Corporation, (b) the Corporation and one or more of its
subsidiaries or (c) one or more of the Corporation's subsidiaries.

     3. Regarding Voting Rights. The holders of shares of Series C Preferred
Stock shall have the following voting rights:

     (A) Each share of Series C Preferred Stock shall entitle the holder thereof
to a number of votes equal to the Adjustment Number for each share held and,
except as otherwise provided herein or by law, the Series A Preferred Stock, the
Series B Preferred Stock, the Series C Preferred Stock and the


                                      -6-
<PAGE>   8
Common Stock (and any other capital stock of the Corporation entitled to vote)
shall vote together as a single class.

     (B) Unless the vote of a larger percentage is required by law or the
Restated Articles of Incorporation, the affirmative vote of the holders of a
majority of the outstanding shares of Series C Preferred Stock shall be
sufficient to take any action as to which a class vote of the holders of the
Series C Preferred Stock is required by law or the Restated Articles of
Incorporation.

     (C) Whenever, at any time, dividends payable on the Series C Preferred
Stock shall be in arrears for such number of dividend payments as shall include
not less than 540 calendar days, the holders of all Preferred Stock (including
holders of the Series C Preferred Stock) upon which these or like voting rights
have been conferred (without limiting the generality of the foregoing, not
including the Series A Preferred Stock and the Series B Preferred Stock) and are
exercisable (the "Voting Preferred Stock") with dividends in arrears for such
number of dividend payments as shall include not less than 540 calendar days,
shall have the exclusive right, voting separately as a class, irrespective of
series, to elect by a majority of the votes cast two directors of the
Corporation, (i) at the Corporation's next annual meeting of shareholders, (ii)
at a special meeting held in place thereof, (iii) at a special meeting of the
holders of shares of the Voting Preferred Stock called by the Secretary of the
Corporation upon the written request of the holders of record of 25% or more of
the total number of shares of Voting Preferred Stock then outstanding, to be
held within 30 days after delivery of such request, or (iv) by written consent
of the holders of a majority of the issued and outstanding shares of Voting
Preferred Stock in lieu thereof, and at each meeting of shareholders thereafter
at which directors shall be elected until such rights shall terminate as
hereinafter provided. The Board of Directors of the Corporation hereby
unanimously directs the Secretary of the Corporation to give notice of any
special meeting of the shareholders of the Corporation required from time to
time by the provisions of this paragraph, in the manner prescribed by the Bylaws
of the Corporation. Upon the vesting of such voting right in the holders of the
Voting Preferred Stock, the maximum authorized number of members of the Board of
Directors shall automatically be increased by two and the two vacancies so
created shall be filled by vote of the holders of the Voting Preferred Stock as
hereinabove set forth. The right of the holders of the Voting Preferred Stock,
voting separately as a class, to elect members of the Board of Directors of the
Corporation as aforesaid shall continue until such time as all dividends
accumulated on the Series C Preferred Stock shall have been paid in full, at
which time such right shall terminate, except as by law expressly provided,
subject to revesting in the event of each and every subsequent default of the
character above mentioned.  Upon any termination of the right of the holders of
the Voting Preferred Stock to vote for directors as herein provided, the term of
office of all directors then in office elected by such Voting Preferred Stock
voting as a class shall terminate immediately. If the office of any director
elected by the holders of the Voting Preferred Stock becomes vacant by reason of
death, resignation, retirement, disqualification, removal from office, or
otherwise, the remaining director elected by the holders of Voting Preferred
Stock voting as a class may choose a successor who shall hold office for the
unexpired


                                      -7-
<PAGE>   9
term in respect of which such vacancy occurred. Whenever the special voting
powers vested in the holders of the Voting Preferred Stock shall have expired,
the number of directors shall become such number as may be provided for in the
Bylaws, or resolution of the Board of Directors thereunder, irrespective of any
increase made pursuant to the provisions of this paragraph 3.

     (D) At any time that any shares of Series C Preferred Stock are
outstanding, the Restated Articles of Incorporation, as amended, of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of Series C Preferred Stock so
as to affect them adversely without the affirmative vote of the holders of a
majority or more of the outstanding shares of Series C Preferred Stock, voting
separately as a class.

     4. Priority in Event of Dissolution. (A) Upon any liquidation (voluntary or
otherwise), dissolution or winding up of the Corporation, no distribution shall
be made to the holders of shares of stock ranking junior (either as to dividends
or upon liquidation, dissolution or winding up) to the Series C Preferred Stock
unless, prior thereto, the holders of shares of Series C Preferred Stock shall
have received $100 per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series C Liquidation Preference"). Following the payment of
the full amount of the Series C Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series C Preferred Stock
unless, prior thereto, the holders of shares of Common Stock shall have received
an amount per share (the "Common Adjustment") equal to the quotient obtained by
dividing (i) the Series C Liquidation Preference by (ii) the Adjustment Number.
Following the payment of the full amount of the Series C Liquidation Preference
and the Common Adjustment in respect of all outstanding shares of Series C
Preferred Stock and Common Stock, respectively, holders of Series C Preferred
Stock and holders of shares of Common Stock shall receive their ratable and
proportionate share of the remaining assets to be distributed in the ratio of
the Adjustment Number to 1 with respect to such Series C Preferred Stock and
Common Stock, on a per share basis, respectively.

     (B) In the event, however, that there are not sufficient assets available
to permit payment in full of the Series C Liquidation Preference and the
liquidation preferences of all other series of Preferred Stock, if any, that
rank on a parity with Series C Preferred Stock, then such remaining assets shall
be distributed ratably to the holders of such parity shares (including the
Series C Preferred Stock) in proportion to their respective liquidation
preferences.

     5. Consolidation, Merger, etc. In case the Corporation shall enter into any
consolidation, merger, combination or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case the shares of Series C
Preferred Stock shall at the same time be similarly exchanged or changed in an
amount per share equal to the Adjustment Number times the aggregate amount of
stock, securities, cash and/or any other property (payable in kind), as the case


                                      -8-
<PAGE>   10
may be, into which or for which each share of Common Stock is changed or
exchanged.

     6. Ranking. The Series C Preferred Stock shall rank junior to the Series A
Preferred Stock and Series B Preferred Stock as to the payment of dividends and
distribution of assets, and shall also rank junior to all other series of the
Corporation's Preferred Stock as to the payment of dividends and the
distribution of assets, unless the terms of any such series shall provide
otherwise.

     7. Fractional Shares. The Series C Preferred Stock may be issued in
fractions of a share that shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series C Preferred Stock.

     8. Sinking Fund. The Series C Preferred Stock shall not be entitled to any
mandatory redemption or prepayment (except on liquidation, dissolution or
winding up of the affairs of the Corporation) or to the benefit of any sinking
fund.

     9. Amount. The number of shares of Series C Preferred Stock may be
increased or decreased by resolution of the Board of Directors; provided,
however, that no decrease shall reduce the number of shares of Series C
Preferred Stock to less than the number of shares then issued and outstanding
plus the number of shares issuable upon exercise of outstanding rights, options
or warrants or upon conversion of outstanding securities issued by the
Corporation.

     10. Definition. If the day upon which any payment is to be made or any
other action is to be taken or any event is scheduled to occur pursuant to the
terms of these Articles of Amendment is not a business day, the payment shall be
made or the other action shall be taken on the next succeeding business day. A
"business day" is defined as a day in the City of Houston, County of Harris,
Texas, that is not a legal holiday or a day on which banking institutions are
authorized or obligated by law to close.

     11. Notice. Except as otherwise provided herein, any notice, demand or
other communication shall be deemed given and received as of the date of
delivery in person or receipt set forth on the return receipt. The inability to
deliver because of rejection or other refusal to accept any notice, demand or
other communication, shall be deemed to be receipt of such notice, demand or
other communication as of the date of such inability to deliver or rejection or
refusal to accept.

     2. Paragraph E of Article III is relettered as paragraph F.

     APPEARERS further stated that all of the shares of the Corporation have par
value; that the Corporation is authorized to issue 50,000,000 shares, of which
40,000,000 are common shares of the par value of $1.25 per share and 10,000,000
are preferred shares of the par value of $0.05 per share; that of the


                                      -9-
<PAGE>   11
preferred shares, 1,999,998 shares have been designated as the Series A
Preferred Stock, 960,000 have been designated as the Series B Preferred Stock,
and 400,000 have been designated as the Series C Preferred Stock; and that the
Board of Directors of the Corporation has the authority to amend the Articles to
fix the preferences, limitations, and relative rights of the preferred shares,
and to establish, and fix variations and relative rights and preferences as
between series of preferred shares, all as more fully set out in Article III of
the Restated Articles of Incorporation.

     AND SAID APPEARERS having requested me, Notary, to note said amendment in
authentic form, I do by these presents receive said amendment in the form of
this public act to the end that said amendment may be promulgated and recorded
and thus be read into the Restated Articles of Incorporation of Southdown, Inc.,
as hereinabove set forth.

     THUS DONE AND PASSED, in my office at Houston, Harris County, State of
Texas, on the day, month and year first above written, in the presence of the
undersigned competent witnesses, who hereunto sign their names with the said
appearers and me, Notary, after a due reading of the whole.

Secretary), a corporation organized and existing under the laws of the State of
Louisiana, domiciled in the Parish of Orleans, State of Louisiana, organized by
Articles of Incorporation effective April 4, 1930, which Articles, as amended,

     BE IT KNOWN, That on this 25th day of January, 1994

     BEFORE ME, Michelle Raymond, a Notary Public, duly commissioned and 
qualified in and for the County of Harris, State of Texas, and in the presence 
of the witnesses hereinafter named and undersigned:

                         PERSONALLY CAME AND APPEARED:

     EDGAR J. MARSTON III and WENDELL E. PHILLIPS, II, appearing herein and
acting for Southdown, Inc. (of which Corporation they are, respectively,
Executive Vice President and General Counsel and Secretary), a corporation
organized and existing under the laws of the State of Louisiana, domiciled in
the Parish of Orleans, State of Louisiana, organized by Articles of
Incorporation effective April 4, 1930, which Articles, as amended, were restated
pursuant to Restated Articles of Incorporation effective September 15, 1983, and
further amended as of April 10, 1987, December 2, 1987, April 23, 1988 and March
4, 1991 ("the Corporation"), who declared that pursuant to Sections 24B(6) and
33A of the Louisiana Business Corporation Law, Article IIIB of the Restated
Articles of Incorporation of the Corporation, resolutions of the Board of
Directors of the Corporation adopted at special meetings of the Board of
Directors of the Corporation held on November 22, 1993 and January 20, 1994, and
resolutions of its duly authorized Special Committee unanimously adopted at a
special meeting of such committee held on January 20, 1994, they now appear for
the purpose of executing this act of amendment and putting into authentic form
the amendment so adopted by the Special Committee of the Board of Directors of
the Corporation.

     AND THE SAID APPEARERS further declare that by unanimous vote of the duly
authorized Special Committee of the Board of Directors of the Corporation, it
was resolved that Article III of the Restated Articles of Incorporation of the
Corporation be further amended as follows:

     1.   There is added as a new paragraph F of Article III the following:

          F.   Of the aforesaid 10,000,000 shares of Preferred Stock, 1,725,000 
shares shall constitute a separate series of preferred shares designated 
"Preferred Stock, $2.875 Cumulative Convertible Series D" (hereinafter called 
the
<PAGE>   7
"Series D Preferred Stock"), which shall have a stated value of $50.00 per 
share. The preferences, limitations and relative rights of the Series D 
Preferred Stock are as follows:

            PREFERRED STOCK, $2.875 CUMULATIVE CONVERTIBLE SERIES D

     (1)  Dividends. The holders of the Series D Preferred Stock shall be
entitled to receive, when and as declared by the Board of Directors, out of the
funds of the Corporation legally available therefor, subject to the prior and
superior rights of the holders of the Corporation's Preferred Stock, $.70
Cumulative Convertible Series A (the "Series A Preferred Stock") and any other
shares of any series or class of stock of the Corporation ranking senior to the
Series D Preferred Stock as to dividends, but pari passu with the Corporation's
Preferred Stock, $3.75 Convertible Exchangeable Series B (the "Series B
Preferred Stock") and any other shares of any series or class of stock of the
Corporation ranking senior to the Series D Preferred Stock as to dividends, but
pari passu with the Corporation's Preferred Stock, $3.75 Convertible
Exchangeable Series B (the "Series B Preferred Stock") and any other shares of
any series or class of stock of the Corporation ranking pari passu with the
Series D Preferred Stock as to dividends, and in preference to the holders of
the Corporation's Preferred Stock, Cumulative Junior Participating Series C (the
"Series C Preferred Stock") that may be issued and the holders of the Common
Stock of the Corporation and any other stock of the Corporation ranking junior
to the Series D Preferred Stock as to dividends, cumulative preferential
dividends per share of Series D Preferred Stock in cash at the rate per annum of
$2.875, and no more, until conversion or redemption. Dividends on the Series D
Preferred Stock will be cumulative, will accrue from the date of original
issuance and will be paid (when and as declared by the Board of Directors of the
Corporation) in cash quarterly, in arrears, on the first day of each April,
July, October and January, commencing on April 1, 1994. Each such regular
dividend on the Series D Preferred Stock shall be paid to the holders of record
of shares of the Series D Preferred Stock as they appear on the stock register
of the Corporation on such record date, not exceeding 30 days preceding the
payment date thereof, as shall be fixed by the Board of Directors of the
Corporation. Dividends on account of arrears for any past dividend periods may
be declared and paid at any time, without reference to any regular dividend
payment date, to the holders of record on such date, not exceeding 45 days
preceding the payment date thereof, as may be fixed by the Board of Directors of
the Corporation. No dividend may be declared on any other series or class of
stock ranking on a parity with the Series D Preferred Stock as to dividends in
respect of any dividend period, unless there shall also be or have been on the
Series D Preferred Stock like dividends for all periods at the dividend rates
fixed therefor. In the event that full cumulative dividends on the Series D
Preferred Stock have not been paid or declared and

                                      -2-
<PAGE>   8
set apart for payment, the Corporation may not declare or pay or set apart for 
payment any dividends or make any other distributions on, or make any payment 
on account of the purchase, redemption or retirement of, the Common Stock or 
any other stock of the Corporation ranking as to dividends or distributions of 
assets on liquidation, dissolution or winding up of the Corporation junior to 
the Series D Preferred Stock (other than, in the case of dividends or 
distributions, dividends or distributions paid in shares of Common Stock or 
such other junior ranking stock), until full cumulative dividends on the Series 
D Preferred Stock are paid or declared and set apart for payment.

     (2)  Redemption.    (a) Shares of Series D Preferred Stock shall be 
redeemable for cash, at the option of the Corporation, in whole or in part at 
any time or from time to time on or after January 27, 2001, at a redemption 
price of $50 per share of Series D Preferred Stock, plus an amount equal to 
accrued and unpaid dividends (whether or not declared) to the date fixed for 
redemption. If the date of redemption falls after a dividend payment record 
date but before the related payment date, the record holders of the Series D 
Preferred Stock on that record date shall be entitled to receive the dividend 
payable on the Series D Preferred Stock notwithstanding the redemption thereof. 
Except as provided in this subparagraph (2)(a), no payment or allowance shall 
be made for accrued dividends on any shares of Series D Preferred Stock called 
for redemption.

     (b)  In case of the redemption of only part of the Series D Preferred 
Stock at the time outstanding, such redemption shall be made pro rata or by lot 
or in such other manner as the Board of Directors of the Corporation may 
determine; provided, however, that the Corporation shall not be required to 
effect the redemption in any manner that results in additional fractional 
shares being outstanding. If full cumulative dividends on the outstanding 
shares of Series D Preferred Stock shall not have been paid or declared and set 
apart for payment for all regular dividend payment dates to and including the 
last dividend payment date prior to the date fixed for redemption, the 
Corporation shall not call for redemption any shares of Series D Preferred 
Stock unless all such shares then outstanding are called for simultaneous 
redemption.

     (c)  Notice of any proposed redemption of Series D Preferred Stock shall 
be given by the Corporation not less than 30 days nor more than 60 days prior 
to the date fixed for such redemption to each holder of record of the shares to 
be redeemed at the address appearing on the books of the Corporation. Notice of 
redemption shall be deemed to have


                                      -3-
<PAGE>   9
been given when deposited in the United States mails, first class mail, postage 
prepaid, whether or not such notice is actually received. If on or before the 
redemption date specified in such notice all funds necessary for such 
redemption shall have been made available at the office of the transfer agent, 
in trust for the pro rata benefit of the holders of the shares so called for 
redemption, so as to be and continue to be available therefor, then from and 
after the date of redemption so designated, notwithstanding that any 
certificate representing shares of Series D Preferred Stock so called for 
redemption shall not have been surrendered for cancellation, the shares 
represented thereby shall no longer be deemed outstanding, the right to receive 
dividends thereon shall cease to accrue and all rights with respect to such 
shares of Series D Preferred Stock so called for redemption shall forthwith at 
the close of business on such redemption date cease and terminate, except only 
the right of the holders thereof to receive the redemption price of such shares 
so to be redeemed plus an amount equal to accrued and unpaid dividends (whether 
or not declared) to the date fixed for redemption, but without interest thereon.

     (d)  Any monies so set aside by the Corporation and unclaimed at the end 
of three years from the date fixed for redemption shall revert to the general 
funds of the Corporation.

     (e)  The Corporation may, however, prior to the redemption date 
specified in the notice of redemption, deposit in trust for the account of 
the holders of the shares of Series D Preferred Stock to be redeemed, with a 
bank or trust company in good standing organized under the laws of the United 
States of America or of any state thereof, having its principal office located 
in the continental United States, and having a capital, surplus and undivided 
profits aggregating at least $50 million, designated in such notice of 
redemption, all funds necessary for such redemption (including accrued and 
unpaid dividends up to the date fixed for redemption), together with 
irrevocable written instructions authorizing such bank or trust company, on 
behalf and at the expense of the Corporation, to cause the notice of redemption
to be mailed as herein provided at least 30 days but not more than 60 days prior
to the redemption date and to include in said notice of redemption a statement
that all funds necessary for such redemption have been so deposited in trust and
are immediately available, and from and after the redemption date,
notwithstanding that any certificate representing shares of Series D Preferred
Stock so called for redemption shall not have been surrendered for cancellation,
the shares represented thereby shall no longer be deemed outstanding and all
rights with respect to such shares of Series D Preferred Stock shall 


                                      -4-
<PAGE>   10
forthwith at the close of business on such redemption date cease and terminate,
except only the right of the holders thereof to receive from such bank or trust
company, at any time after the redemption date, the redemption price of such
shares so to be redeemed plus accrued and unpaid dividends (whether or not
declared) to the date fixed for redemption, but without interest thereon. In the
event the holder of any such shares of Series D Preferred Stock shall not,
within three years after the redemption date, claim the amount deposited for the
redemption thereof, the depositary shall, upon the request of the Corporation
expressed in a resolution of its Board of Directors, pay over to the Corporation
such unclaimed amount after which time the holders of the shares so called for
redemption shall look only to the Corporation for the payment thereof.

     (f)  If any shares of Series D Preferred Stock called for redemption are
not issued and outstanding as of the date fixed for redemption, the amount set
aside or deposited for the redemption thereof shall revert to or be paid over to
the Corporation.

     (g)  Any shares of Series D Preferred Stock which are redeemed or otherwise
purchased or acquired by the Corporation or any subsidiary thereof shall be
cancelled. The number of shares of Series D Preferred Stock shall be reduced by
the number of shares so cancelled and such cancelled shares shall be restored to
the status of authorized but unissued shares of Preferred Stock, without
designation as to series, and may thereafter be issued but not as shares of
Series D Preferred Stock. For the purposes of this paragraph, a subsidiary means
a corporation of which a majority of the capital stock having voting power under
ordinary circumstances to elect a majority of the board of directors is owned by
(a) the Corporation, (b) the Corporation and one or more of its subsidiaries or
(c) one or more of the Corporation's subsidiaries.

     (3)  Regarding Voting Rights. (a) Each share of Series D Preferred Stock
shall entitle the holder thereof to one vote and, except as provided herein or
as required by law, the Series D Preferred Stock and the Common Stock (and any
other capital stock of the Corporation at any time entitled to vote) shall vote
together as a single class.

     (b)  In addition to any provisions herein and any requirement of law, the 
Series D Preferred Stock shall vote as a single class with respect to any 
proposal (i) to change the dividend rate, liquidation preference, redemption 
price, voting rights or conversion rights of the shares of Series D Preferred 
Stock or to increase the number of authorized shares of Series D Preferred 
Stock; (ii) to increase the authorized


                                      -5-
<PAGE>   11
amount of any series or class of capital stock of the Corporation that ranks 
senior to the Series D Preferred Stock as to dividends or distribution of 
assets on liquidation; (iii) to authorize, create, issue or sell any shares of 
any series or any class of capital stock of the Corporation that ranks senior 
to the Series D Preferred Stock as to dividends or assets upon liquidation; 
(iv) to change or modify the voting rights of the Series D Preferred Stock and 
(v) for the alteration, change or modification of the rights set forth in this 
subparagraph (3)(b). The affirmative vote of the holders of at least two-thirds 
of the outstanding shares of Series D Preferred Stock shall be required to take 
any action on the matters specified in clauses (i) through (v) of this 
subparagraph (3)(b).

     (c)  Unless the vote of a larger percentage is required by law or the 
Articles of Incorporation, the affirmative vote of the holders of a majority of 
the outstanding shares of Series D Preferred Stock entitled to vote on the 
matter shall be sufficient to take any action as to which a class vote of the 
holders of the Series D Preferred Stock is required by law or the Articles of 
Incorporation.

     (d)  Whenever, at any time, dividends payable on the Series D Preferred 
Stock shall be in arrears for six quarterly dividend periods, the holders of 
all classes or series of preferred stock which rank pari passu with the Series 
D Preferred Stock as to dividends and which shall specifically state that they 
shall vote with the Series D Preferred Stock for the election of two directors 
in such a case (specifically excluding the Series A Preferred Stock, the Series 
B Preferred stock and the Series C Preferred Stock) (the "Voting Preferred 
Stock"), shall have the exclusive right, voting separately as a class, 
irrespective of class or series, to elect by a plurality of the votes cast two 
directors of the Corporation, who shall be a Class I director and a Class II 
director, respectively, (i) at the Corporation's next annual meeting of 
shareholders, (ii) at a special meeting held in place thereof, (iii) at a 
special meeting of the holders of shares of the Voting Preferred Stock called 
by the Secretary of the Corporation upon the written request of the holders of 
record of 25% or more of the total number of shares of Voting Preferred Stock 
then outstanding, to be held within 30 days after delivery of such request, or 
(iv) by written consent of the holders of a majority of the issued and 
outstanding shares of Voting Preferred Stock in lieu thereof, and at each 
succeeding meeting of shareholders thereafter at which directors shall be 
elected until such rights shall terminate as hereinafter provided. The Board of 
Directors of the Corporation hereby unanimously directs the Secretary of the 
Corporation to give notice of any special meeting of the


                                      -6-
<PAGE>   12
shareholders of the Corporation required from time to time by the provisions of
this paragraph (3), in the manner prescribed by the Bylaws of the Corporation.
At elections for such directors, each holder of the Voting Preferred Stock shall
be entitled to one vote for each share held. Upon the vesting of such voting
right in the holders of the Voting Preferred Stock, the maximum authorized
number of members of the Board of Directors shall automatically be increased by
two and the two vacancies so created shall be filled by vote of the holders of
the Voting Preferred Stock as hereinabove set forth. The right of the holders of
the Voting Preferred Stock, voting separately as a class, to elect members of
the Board of Directors of the Corporation as aforesaid shall continue until such
time as all dividends accumulated on the voting Preferred Stock shall have been
paid in full, at which time such right shall terminate, except as by law
expressly provided, subject to revesting in the event of each and every
subsequent default of the character above mentioned. Upon any termination of the
right of the holders of the Voting Preferred Stock to vote for directors as
herein provided, the term of office of all directors then in office elected by
such Voting Preferred Stock voting as a class shall terminate immediately. If
the office of any director elected by the holders of the Voting Preferred Stock
becomes vacant by reason of death, resignation, retirement, disqualification,
removal from office or otherwise, the remaining director elected by the holders
of Voting Preferred Stock voting as a class may choose a successor who shall
hold office for the unexpired term in respect of which such vacancy occurred.
Whenever the special voting powers vested in the holders of the Voting Preferred
Stock shall have expired, the number of directors shall become such number as
may be provided for in the By-Laws, or resolution of the Board of Directors
thereunder, irrespective of any increase made pursuant to the provisions of this
subparagraph (3)(d).

     (4) Priority in Event of Dissolution. In the event of any liquidation, 
dissolution, or winding up of the affairs of the Corporation, after payment or 
provision for payment of the debts and other liabilities of the Corporation 
(including any liquidation preferences payable in respect of the Series A 
Preferred Stock and any other capital stock of the Corporation ranking senior 
to the Series D Preferred Stock as to assets), the holders of the Series D 
Preferred Stock shall be entitled to receive, out of the remaining net assets 
of the Corporation, $50.00 in cash for each share of Series D Preferred Stock, 
plus an amount equal to all dividends accrued and unpaid on each such share 
(whether or not declared) up to the date fixed for distribution, before any 
distribution shall be made to the holders of the Common Stock of the 
Corporation, the Series C Preferred Stock or any other stock of the 


                                      -7-
<PAGE>   13
Corporation ranking junior to the Series D Preferred Stock as to assets. If 
upon any liquidation, dissolution or winding up of the affairs of the 
Corporation, the assets distributable among the holders of the Series D 
Preferred Stock, the Series B Preferred Stock and any other capital stock of 
the Corporation ranking on a parity with the Series D Preferred Stock as to 
assets shall be insufficient to permit the payment in full to the holders of 
all shares of such Series D Preferred Stock, the Series B Preferred Stock and 
any other capital stock of the Corporation ranking on a parity with the Series 
D Preferred Stock as to assets of all preferential amounts payable to all such 
holders, then the entire assets of the Corporation thus distributable shall be 
distributed ratably among the holders of the Series D Preferred Stock, the 
Series B Preferred Stock and any other capital stock of the Corporation ranking 
on a parity with the Series D Preferred Stock as to assets in proportion to the 
respective amounts that would be payable per share if such assets were 
sufficient to permit payment in full.

     (5) Conversion at Option of Holder. (a) Subject to and upon compliance with
the provisions herein, at the option of the holder, shares of Series D Preferred
Stock may at any time be converted into fully paid and nonassessable shares of
common stock at the rate of 1.511 shares of Common Stock for each share of
Series D Preferred Stock to be converted (subject to adjustment as hereinafter
provided) (the "Conversion Rate"); provided, however, that if the Corporation
shall have given notice of redemption of any shares of Series D Preferred Stock
pursuant to paragraph (2) above or notice of conversion at the option of the
Corporation pursuant to paragraph (6) below, such right to convert such shares
shall terminate at 5:00 p.m., New York City time, on the date fixed for
redemption or such conversion, respectively (unless the Corporation shall
default in the payment due upon redemption in which case such conversion rights
shall not expire). The result obtained by dividing $50.00 by the Conversion Rate
in effect from time to time is herein referred to as the "Conversion Price." The
initial conversion Price shall be $33.092. Whenever the Conversion Price is
adjusted pursuant to the provisions of subparagraph (7)(c) below, the Conversion
Rate shall be redetermined by dividing $50.00 by the then adjusted Conversion
Price. The Conversion Rate and the Conversion Price in effect from time to time
shall be calculated to four decimal places and rounded to the nearer
thousandths.

     (b) In order to exercise the right to convert, the holder of any shares of 
Series D Preferred Stock to be converted shall surrender the certificate 
representing such shares of Series D Preferred Stock, accompanied (if so


                                      -8-
<PAGE>   14
required by the Corporation) by the proper instrument or instruments of
transfer, in form satisfactory to the Corporation, duly executed by the
registered holder thereof or by his attorney duly authorized in writing, to the
transfer agent of the Series D Preferred Stock or at such other office or
offices, if any, as the Board of Directors shall designate and shall give
written notice to the Corporation at such office that the holder elects to
convert such Series D Preferred Stock. Such shares of Series D Preferred Stock
surrendered for conversion shall be deemed to have been converted immediately
prior to the close of business on the date of the giving of such notice and of
the surrender of such certificates for conversion in accordance with the
foregoing provisions, and at such time the rights of the holder of such Series D
Preferred Stock as such holder shall cease, and the holder thereof shall be
treated for all purposes as the record holder of Common Stock from and after
such time. As promptly as practicable after receipt of such notice and the
surrender of such certificates as aforesaid, the Corporation shall issue and
deliver at such office a certificate or certificates for the number of full
shares of Common Stock issuable upon conversion.

     (6)  Conversion at Option of Corporation. (a) On and after January 27, 1997
and until January 27, 2001, shares of Series D Preferred Stock outstanding are
convertible, at the option of the Corporation, in whole but not in part, at any
time, into fully paid and non-assessable shares of Common Stock. The Corporation
may exercise this option only if for at least 20 trading days within any period
of 30 consecutive trading days, including the last trading day of such period,
the Market Price (as defined below) of the Common Stock exceeds 130 percent of
the Conversion Price on such respective dates and only if all dividends on the
Series D Preferred Stock for all dividend periods ending on or prior to the
dividend payment date next preceding the Conversion Date (as defined herein)
have been paid or set aside for payment. 

     (b)  In order to exercise its option to convert shares of the Series D
Preferred Stock, the Corporation must, not fewer than 15 nor more than 60 days
before the date of such conversion (the "Conversion Date"), issue a press
release announcing the conversion and specifying the Conversion Date, which
announcement shall be made prior to 9:00 A.M., New York City time, of the second
trading day after the end of any such 30-day trading period. The Corporation
shall also give notice of such conversion to the holders of record of shares of
Series D Preferred Stock to be converted at the holders' addresses shown on the
books of the Corporation. Notice of such conversion must be given by first class
mail, postage per-paid, not fewer than 15 or more than 60 days before the 


                                      -9-
<PAGE>   15
Conversion Date and must state:  (i) the Conversion Date; (ii) the Conversion
Rate and the Conversion Price as of the date immediately preceding the date of
the notice; (iii) the place or places where certificates for the shares of
Series D Preferred Stock may be surrendered in exchange for certificates for
shares of the Common Stock; and (iv) that dividends on the shares of the Series
D Preferred Stock to be converted will cease to accrue on the Conversion Date.
Notice is given when deposited in the United States mail, by first class mail,
postage prepaid, whether or not actually received. The Corporation's failure to
mail such notice to a shareholder shall not affect the validity or effectiveness
of the conversion of the shares of Series D Preferred Stock into shares of
Common Stock.

          (c)  On the date fixed by the Corporation as of the Conversion Date, 
the rights of the holders of the shares of Series D Preferred Stock as such 
shall cease, the shares of Series D Preferred Stock to be converted shall no 
longer be deemed outstanding, dividends thereon shall cease to accrue and 
certificates for such shares shall represent (i) the shares of Common Stock 
issuable on conversion of the Series D Preferred Stock evidenced thereby and 
(ii) the right to receive the amounts payable under Section 7(b) in lieu of the 
issuance of any fractional share.

          (d)  The number of shares of Common Stock issuable for each share of 
Series D Preferred Stock so converted shall be equal to the product of the 
number of shares of Series D Preferred Stock being converted and the Conversion 
Rate in effect as of the Conversion Date.

     (7)  General Provisions Regarding Conversion. The following provisions
shall be applicable to all conversions of Series D Preferred Stock pursuant to
paragraphs (5) and (6):

          (a)  If the Conversion Date falls after a dividend payment record 
date but before the related payment date, the record holder of the Series D 
Preferred Stock on that record date shall be entitled to receive the dividend 
payable on the Series D Preferred Stock notwithstanding the conversion 
thereof.  Except as provided in this subparagraph (a), no payment or allowance 
shall be made for accrued dividends on any shares of Series D Preferred 
Stock converted or surrendered for conversion.

          (b)  No fractional share of Common Stock shall be issued upon 
conversion of Series D Preferred Stock. Instead of any fractional share of 
Common Stock which would otherwise be issuable upon conversion of any Series D 
Preferred Stock, the Corporation shall pay a cash adjustment equal to such


                                      -10-
<PAGE>   16
fraction multiplied by the Market Price per share of the Common Stock (as
defined below) on the trading day next preceding the date of conversion. In
determining the number of shares of Common Stock and the payment, if any, in
lieu of fractional shares that a holder of Series D Preferred Stock shall
receive, the total number of shares of Series D Preferred Stock surrendered for
conversion by such holder shall be aggregated.

          (c)  The number and kind of securities issuable upon the conversion of
the Series D Preferred Stock shall be subject to adjustment from time to time
upon the happening of certain events occurring on or after the date of original
issue of the shares of the Series D Preferred Stock as follows:

               (i)  In case of any reclassification or change of Common Stock
     issuable upon exercise of these conversion rights (other than a change in
     par value, or from par value to no par value, or from no par value to par
     value or as a result of a subdivision or combination), or in case of any
     consolidation or merger of the Corporation with or into another corporation
     (other than a merger with another corporation in which the Corporation is
     the surviving Corporation and which does not result in any reclassification
     or change -- other than a change in par value, or from par value to no par
     value, or from no par value to par value, or as a result of a subdivision
     or combination -- of Common Stock issuable upon exercise of these
     conversion rights), or in the case of a sale or conveyance in a single
     transaction or in a series of related transactions with the same purchaser
     or affiliates thereof of all or substantially all the assets of the
     Corporation as an entirety, or a statutory share exchange in which all
     shares of Common Stock are exchanged for shares of another corporation or
     entity, the holders of the Series D Preferred Stock shall have, and the
     Corporation, or such successor entity or purchaser, shall covenant in the
     constituent documents effecting any of the foregoing transactions that the
     holders of the Series D Preferred Stock do have, the right to obtain upon
     the exercise of these conversion rights, in lieu of each share of Common
     Stock theretofore issuable upon exercise of these conversion rights, the
     kind and amount of shares of stock, other securities, money and property
     receivable upon such reclassification, change, consolidation or merger,
     conveyance or sale of assets or share exchange by a holder of one share of
     Common Stock issuable upon exercise of these conversion rights as if they
     had been exercised immediately prior to such reclassification,




                                      -11-
<PAGE>   17
     change, consolidation or merger, conveyance or sale of assets or share
     exchange. The constituent documents effecting any reclassification, change,
     consolidation or merger, or share exchange shall provide for adjustments
     which shall be as nearly equivalent as may be practicable to the
     adjustments provided in this subparagraph (c). The provisions of this
     subparagraph (c)(i) shall similarly apply to successive reclassifications,
     changes, consolidations or mergers, conveyances or sales of assets or share
     exchanges.

          (ii)   If the Corporation at any time while any of the Series D
     Preferred Stock is outstanding shall subdivide or combine its Common Stock,
     the Conversion Price shall be proportionately reduced, in case of
     subdivision of shares, as at the effective date of such subdivision, or if
     the Corporation shall take a record of holders of its Common Stock for the
     purpose of so subdividing, as at such record date, whichever is earlier, or
     shall be proportionately increased, in the case of combination of shares,
     as at the effective date of such combination or, if the Corporation shall
     take a record of holders of its Common Stock for the purpose of so
     combining, as at such record date, whichever is earlier.

          (iii)  If the Corporation at any time while any of the Series D
     Preferred Stock is outstanding shall pay to any holders of stock of the
     Corporation a dividend payable in, or make any other distribution of,
     Common Stock, the Conversion Price shall be adjusted, as of the date the
     Corporation shall take a record of the holders of such stock for the
     purpose of determining the holders entitled to receive such dividend or
     other distribution (or if no such record is taken, as at the date of such
     payment or other distribution), to that price determined by multiplying the
     Conversion Price in effect immediately prior to such record date (or if no
     such record is taken, then immediately prior to such payment or other
     distribution) by a fraction (1) the numerator of which shall be the total
     number of shares of Common Stock outstanding immediately prior to such
     dividend or distribution, and (2) the denominator of which shall be the
     total number of shares of Common Stock outstanding immediately after such
     dividend or distribution (plus in the event that the Corporation paid cash
     for fractional shares, the number of additional shares which would have
     been outstanding had the Corporation issued fractional shares in connection
     with said dividend, except to the extent such payment of cash is treated as
     a dividend payable out of earnings or surplus legally available for




                                      -12-
<PAGE>   18
     the payment of dividends under the laws of the State of Louisiana).

          (iv) If the Corporation shall issue to all holders of its Common Stock
     any warrant, option or other right to subscribe for or purchase shares of
     Common Stock at a price per share less than the Market Price of the Common
     Stock, the Conversion Price shall be adjusted, as of the date the
     Corporation shall take a record of the holders of its Common Stock for the
     purpose of receiving such issuance or distribution, to that price
     determined by multiplying the Conversion Price by a fraction, the numerator
     of which shall be the number of shares of Common Stock outstanding on the
     date of issuance of such warrants, options or rights plus the number of
     shares which the aggregate offering price of the total number of shares so
     offered would purchase at such Market Price per share, and the denominator
     of which shall be the number of shares of Common Stock outstanding on the
     date of issuance of such warrants, options or rights plus the number of
     additional shares of Common Stock offered for subscription or purchase.

          (v) If the Corporation shall distribute to all holders of its Common 
     Stock evidences of indebtedness of the Company, shares of capital stock of
     the Corporation (other than Common Stock) or assets or rights or warrants
     to subscribe for or purchase any of its securities (excluding those
     dividends, warrants, options and rights referred to in subparagraph (iv)
     above and dividends and other distributions paid in cash out of the profits
     or surplus of the Corporation legally available therefor under the laws of
     the State of Louisiana) then in each case the Conversion Price shall be
     adjusted, as of the date the Corporation shall take a record of the holders
     of its Common Stock for the purpose of determining the holders entitled to
     receive such issuance or distribution, to that price determined by
     multiplying the Conversion Price by a fraction the numerator of which shall
     be Market Price per share of the Common Stock less the fair market value
     (as determined by the Board of Directors of the Corporation, whose
     determination shall be conclusive) of the portion of the assets, evidences
     of indebtedness for subscription rights so distributed in respect of one
     share of Common Stock and the denominator of which is the Market Price per
     share of Common Stock on the record date for such distribution.

          (vi) No adjustment of the Conversion Price shall be made in an amount 
     less than $.05 per share, but any such lesser adjustment shall be carried 
     forward and shall be


                                      -13-
<PAGE>   19
     made at the time together with the next subsequent adjustment which,
     together with any adjustments so carried forward, shall amount to $.05 per
     share or more.

          (vii) The Market Price per share of Common Stock on any day means the
     closing price for such shares as reported in The Wall Street Journal's
     NYSE-Composite Transactions listing for such day (corrected for obvious
     typographical errors), or if such shares are not reported in such listing,
     then the closing price for such shares on the largest national securities
     exchange (based on the aggregate dollar value of securities listed) on
     which such shares are listed or traded, or if such shares are not listed or
     traded on any national securities exchange, then the closing price for such
     shares in the over-the-counter market, as reported on the National
     Association of Securities Dealers Automated Quotations System, or, if such
     price shall not be reported thereon, the average between the closing bid
     and asked prices so reported, or, if such prices shall not be reported,
     then the average closing bid and asked prices reported by the National
     Quotation Bureau Incorporated, or, in all other cases, the value
     established by the Board of Directors of the Corporation in good faith.

     (d) Whenever the Conversion Price and the Conversion Rate are required to
be adjusted as provided herein, the Corporation shall forthwith compute the
adjusted Conversion Price and the adjusted Conversion Rate and shall prepare a
certificate setting forth such adjusted Conversion Price and adjusted Conversion
Rate showing in detail the facts upon which such adjustment is based. A copy of
such certificate shall forthwith be filed with the transfer agent or agents for
the Series D Preferred Stock (if any) and for the Common Stock; and thereafter,
until further adjusted; the adjusted Conversion Price and the adjusted
Conversion Rate shall be as set forth in such certificate, provided that the
computation of such adjusted Conversion Price and such adjusted Conversion Rate
shall be reviewed at least annually by the independent public accountants
regularly employed by the Corporation and said accountants shall file a
corrected certificate, if shall mail or cause to be mailed to the holders of
Series D Preferred Stock at the time of each quarterly dividend payment, a
statement setting forth the adjustments, if any, made in the applicable
Conversion Price and Conversion Rate and not theretofore reported to such
holders, and the reasons for such adjustment.

     (e) The Corporation will at all times reserve and keep available, out of
its authorized and unissued Common Stock



                                      -14-
<PAGE>   20
solely for the purpose of issuance upon the conversion of the Series D 
Preferred Stock as herein provided, free from preemptive and other subscription 
rights, such number of shares of Common Stock as shall then be issuable upon 
the conversion of all outstanding Series D Preferred Stock. The Corporation 
shall ensure that all shares of Common Stock which shall be so issuable shall 
upon issue be duly and validly issued and fully paid and nonassessable.

     (f)  If any shares of Common Stock required to be reserved for the purposes
of conversion of Series D Preferred Stock hereunder require registration with or
approval of any governmental authority under any federal or state law, or
listing upon any national securities exchange, before such shares may be issued
upon conversion, the Corporation will in good faith and as expeditiously as
possible endeavor to cause such shares to be duly registered, approved or
listed, as the case may be.

     (g)  The issuance of certificates for shares of Common Stock upon the
conversion of Series D Preferred Stock shall be made without charge to the
holders thereof for any transfer or similar taxes that may be payable in respect
of the issue, delivery or acquisition of such certificates. Such certificates
shall be issued in the respective names of the holders of the Series D Preferred
Stock converted.

     (8)  Sinking Fund. The Series D Preferred Stock shall not be entitled to
any mandatory redemption or prepayment (except on liquidation, dissolution or
winding up of the affairs of the Corporation) or to the benefit of any sinking
fund.

     (9)  Definition. If the day upon which any payment is to be made or any
other action is to be taken or any event is scheduled to occur pursuant to the
terms of Articles of Amendment is not a business day, the payment shall be made
or the other action shall be taken on the next succeeding business day. A
"business day" is defined as a day in the City of Houston, County of Harris,
Texas, that is not a legal holiday or a day on which banking institutions are
authorized or obligated by law to close.

     2.   Existing Paragraph F of Article III is relettered as Paragraph G.

     APPEARERS further stated that all of the shares of the Corporation have par
value; that the Corporation is authorized to issue 50,000,000 shares, of which
40,000,000 are common shares of the par value of $1.25 per share and 10,000,000
are preferred shares of the par value of $0.05 per share; and that


                                      -15-

the Board of Directors of the Corporation and the Special Committee thereof each
has the authority to amend the articles to fix the preferences, limitations and
relative rights of the preferred shares, and to establish, and fix variations
and relative rights and preferences as between series of preferred shares, all
as more fully set out in Article III of the Restated Articles of Incorporation.

     AND SAID APPEARERS having requested me, Notary, to note said amendment in
authentic form, I do by these presents receive said amendments in the form of
this public act to the end that said amendment may be promulgated and recorded
and thus be read into the Restated Articles of Incorporation of Southdown, Inc.,

Texas, on the day, month and year first above written, in the presence of the
undersigned competent witnesses, who hereunto sign their names with the said

of Harris, State of Texas, and in the presence of the witnesses hereinafter

                          PERSONALLY CAME AND APPEARED:

     EDGAR J. MARSTON III and WENDELL E. PHILLIPS, II, appearing herein and
acting for Southdown, Inc. (of which Corporation they are, respectively,
Executive Vice President and Secretary), a corporation organized and existing
under the laws of the State of Louisiana, domiciled in the Parish of Orleans,
State of Louisiana, organized by Articles of Incorporation effective April 4,
1930, which Articles, as amended, were restated pursuant to Restated Articles
of Incorporation effective September 15, 1983, who declared that pursuant to
resolutions of the shareholders of the Corporation adopted at an annual meeting
of the shareholders of the Corporation held on May 19, 1988 at 10:15 a.m., at
the Doubletree Hotel, 400 Dallas Street, Houston, Texas 77002, they now appear
for the purpose of executing this act of amendment and putting into authentic
form the amendment so agreed to by the shareholders of said Corporation, which

     AND THE SAID APPEARERS further declare that by vote of the shareholders of
said Corporation, it was:

     RESOLVED, that Article III of the Restated Articles of Incorporation of
Southdown, Inc. be amended so that:

     (1)  Paragraph A. is amended to read in its entirety as follows:

               The Corporation has authority to issue 40,000,000 shares of
          Common Stock of the par value of $1.25 per share (the "Common Stock")
          and
<PAGE>   24
          10,000,000 shares of Preferred Stock of the par value of $.05 per
          share (the "Preferred Stock"). Upon the effectiveness of the
          amendments contained in these Articles of Amendment (the "Effective
          Date") each share of common stock of the Corporation issued at the
          close of business on the Effective Date shall be changed and split-up
          into two shares of Common Stock without change in the aggregate amount
          of capital represented by the issued shares, such two-for-one split to
          be accomplished by issuing to each holder of the Corporation's common
          stock of record at the close of business on the Effective Date a
          certificate or certificates at the rate of one additional share of
          Common Stock for each share of the common stock held of record on the
          stock transfer records of the Corporation at the close of business on
          the Effective Date.

     (2)  The first sentence of Paragraph C. is deleted and there is substituted
          in its place the following:

               Of the aforesaid 10,000,000 shares of Preferred Stock, 1,999,998
          shares shall constitute a separate series of preferred shares
          designated "Preferred Stock, $.70 Cumulative Convertible Series A"
          (hereinafter called the "Series A Preferred Stock"), which shall have
          a stated value of $10.00 per share. Upon the Effective Date, in lieu
          of any adjustment of the conversion price or conversion rate
          applicable to the Corporation's Preferred Stock, $1.40 Cumulative
          Convertible Series A (the "Old Series A Preferred Stock") that would
          otherwise result from the foregoing two-for-one stock split of the
          Corporation's common stock under Article III C. of the Restated
          Articles of Incorporation, each share of the Old Series A Preferred
          Stock issued at the close of business on the Effective Date shall be
          changed and split-up into two shares of Series A Preferred Stock
          without change in the aggregate amount of capital represented by the
          issued shares, such two-for-one split to be accomplished by issuing to
          each holder of Old Series A Preferred Stock of record at the close of
          business on the Effective Date a certificate or certificates at the
          rate of one additional share of Series A Preferred Stock


                                      -2-
<PAGE>   25
          for each share of Old Series A Preferred Stock held of record on the
          stock transfer records of the Corporation at the close of business on
          the Effective Date.

     (3)  The first sentence of Subparagraph (1) of Paragraph C. is amended to
          read in its entirety as follows:

               The holders of the Series A Preferred stock shall be entitled to
          receive, when and as declared by the Board of Directors out of the
          funds of the Corporation legally available therefor and in preference
          to the holders of the Common Stock of the Corporation and any other
          capital stock of the Corporation ranking junior to the Series A
          Preferred Stock as to dividends, cumulative preferential dividends per
          share of Series A Preferred Stock in cash at the rate per annum of
          $.70 and no more.

     (4)  The first sentence of Subparagraph (4) of Paragraph C. is amended to
          read in its entirety as follows:

               In the event of any liquidation, dissolution or winding up of the
          affairs of the Corporation, after payment or provision for payment of
          the debts and other liabilities of the Corporation (including any
          liquidation preferences payable in respect of capital stock of the
          Corporation ranking senior to the Series A Preferred Stock as to
          assets), the holders of the Series A Preferred Stock shall be entitled
          to receive, out of the remaining net assets of the Corporation, $10.00
          in cash for each share of Series A Preferred Stock, plus an amount
          equal to all dividends accrued and unpaid on each such share (whether
          or not declared) up to the date fixed for distribution, before any
          distribution shall be made to the holders of the Common Stock of the
          Corporation or any other stock of the Corporation ranking junior to
          the Series A Preferred stock as to assets.


                                      -3-
<PAGE>   26
     (5)  The second and third sentences of Subparagraph (5) of Paragraph C. are
          amended to read in their entirety as follows:

          The result obtained by dividing $5.00 by the conversion rate in effect
          from time to time is herein referred to as the "conversion price."
          Whenever the conversion price is adjusted pursuant to the provisions
          of Subparagraph (d) below, the conversion rate shall be redetermined
          by dividing $5.00 by the then adjusted conversion price.

     (6)  Wherever the phrase "$20.00 stated value" appears in Article III C.,
          such phrase be and it hereby is amended to read "$10.00 stated value."

     (7)  Wherever the term "Preferred Stock, $1.40 Cumulative Convertible
          Series A" appears in Article III C., such term shall be and it hereby
          is amended to read "Preferred Stock, $.70 Cumulative Convertible
          Series A."

     AND SAID APPEARERS further declared that of the outstanding shares of
capital stock of the Corporation 5,353,803 were represented at said meeting and
that 4,913,251 shares were voted for the said amendment and that 440,522 shares
were voted against the said amendment or abstained from voting thereon.

     AND SAID APPEARERS further declared that 712,000 shares of the Series A
Preferred Stock of the Corporation were represented at said meeting, and that
712,000 shares were voted for the said amendment and that no shares were voted
against the said amendment.

     APPEARERS FURTHER stated that all of the shares of the Corporation have
par value; that the Corporation is authorized to issue 50,000,000 shares, of
which 40,000,000 are common shares of the par value of $1.25 per share and
10,000,000 are preferred shares of the par value of $0.05 per share; that of the
preferred shares, 1,999,998 shares have been designated as the Series A
Preferred Stock and 960,000 shares have been designated as the Series B

authority to amend the Articles to fix the preferences, limitations, and
relative rights of the preferred shares, and to establish, and fix variations

<PAGE>   27
relative rights and preferences as between, series of preferred shares, all as
more fully set out in Article III of the Articles of Incorporation.

     AND SAID APPEARERS having requested me, Notary, to note said amendment in
authentic form, I do by these presents receive said amendments in the form of
this public act to the end that said amendment may be promulgated and recorded

          BE IT KNOWN, That on this 23rd day of April, 1988,
          BEFORE ME, W. Cleland Dade, a Notary Public, duly commissioned and
qualified in and for the County of Harris, State of Texas, and in the presence 
of the witnesses hereinafter named and undersigned:

                         PERSONALLY CAME AND APPEARED:

          CLARENCE C. COMER and WENDELL E. PHILLIPS, II, appearing herein and 
acting for Southdown, Inc. (of which Corporation they are, respectively, 
President and Secretary), a corporation organized and existing under the laws 
of the State of Louisiana, domiciled in the Parish of Orleans, State of 
Louisiana, organized by Articles of Incorporation effective April 4, 1930, 
which Articles, as amended, were restated pursuant to Restated Articles of 
Incorporation effective September 15, 1983, who declared that pursuant to 
Sections 24B(6) and 33A of the Louisiana Business Corporation Law, Article IIIB 
of the Restated Articles of Incorporation of the Corporation, and resolutions 
of the Board of Directors of the Corporation adopted at a special meeting of 
the Board of Directors of the Corporation held on April 22, 1988, they now 
appear for the purpose of executing this act of amendment and putting into 
authentic form the amendment so adopted by the Board of Directors of said 
Corporation.

          AND THE SAID APPEARERS further declare that by unanimous vote of the 
Board of Directors of said Corporation, it was resolved that Article III of the 
Restated Articles of Incorporation of Southdown, Inc. be further amended as 
follows:

          1.  There is added as a new paragraph D. of Article III the following:

              D.  Of the aforesaid 5,000,000 shares of Preferred Stock, 960,000
shares shall constitute a separate series of preferred shares designated
"Preferred Stock, $3.75 Convertible Exchangeable series B" (hereinafter called
the "Series B Preferred Stock"), which shall have a stated value of $50.00 per
share. The Corporation has fixed April 7,
<PAGE>   30
1988 as the record date for the annual meeting of shareholders scheduled for May
19, 1988 ("Annual Meeting"). The Board of Directors of the Corporation has
approved and has submitted to the shareholders for their approval at the Annual
Meeting a proposal to split up the Corporation's authorized and issued common
stock and preferred stock on a two-for-one basis. If the stock split is approved
by the shareholders it is expected to become effective on May 27, 1988
("Effective Date"). The shares of Series B Preferred Stock will not be split up
on the Effective Date; however, on the Effective Date, the par value of the
Series B Preferred Stock will be reduced from $.10 per share to $.05 per share
and the number of shares of Common Stock issuable upon the conversion thereof
will be increased pursuant to the provisions of paragraph 5(d)(ii) of these
Articles of Amendment. The preferences, limitations and relative rights of the
Series B Preferred Stock are as follows:

                                PREFERRED STOCK
                    $3.75 CONVERTIBLE EXCHANGEABLE SERIES B

     (1) Dividends. The holders of the Series B Preferred Stock shall be
entitled to receive, when and as declared by the Board of Directors out of the
funds of the Corporation legally available therefor, subject to the prior and
superior rights of the holders of the Corporation's Preferred Stock, $1.40
Cumulative Convertible Series A ("Series A Preferred Stock") to the payment of
dividends, but in preference to the holders of the Common Stock of the
Corporation and any other capital stock of the Corporation ranking junior to the
Series B Preferred Stock as to dividends, cumulative preferential dividends per
share of Series B Preferred Stock in cash at the rate per annum of $3.75 and no
more. The Series B Preferred Stock is issuable upon the conversion of the
Corporation's 7 1/2% Special Convertible Subordinated Debentures Due 2013
("Special Debentures"). Dividends on the Series B Preferred Stock will be
cumulative, will accrue from the last date on which interest is paid on the
Special Debentures and will be paid (when and as declared by the Board of
Directors of the Corporation) in cash semiannually, in arrears, on the last day
of each June and December, commencing on the first such date to occur after the
date of original issuance of the Series B Preferred Stock. Each dividend on the
Series B Preferred Stock shall be paid to the holders of record of shares of the
Series B Preferred Stock as they appear on the stock register of the Corporation
on such record date, not exceeding 30 days preceding the payment date thereof,
as shall be fixed by the Board of Directors of the Corporation. Dividends on


                                      -2-
<PAGE>   31
account of arrears for any past dividend periods may be declared and paid at any
time, without reference to any regular dividend payment date, to holders of
record on such date, not exceeding 45 days preceding the payment date thereof,
as may be fixed by the Board of Directors of the Corporation. No dividend may be
declared on any other series or class of stock ranking on a parity with
the Series B Preferred Stock as to dividends in respect of any dividend period,
unless there shall also be or have been declared on the Series B Preferred
Stock like dividends for all periods at the dividend rates fixed therefor. In
the event that full cumulative dividends on the Series B Preferred Stock have
not been declared and paid or set apart for payment, the Corporation may not
declare or pay or set apart for payment any dividends or make any other
distributions on, or make any payment on account of the purchase, redemption or
retirement of, the Common Stock or any other stock of the Corporation ranking
junior to the Series B Preferred Stock as to dividends or distributions of
assets on liquidation, dissolution or winding up of the Corporation (other than,
in the case of dividends or distributions, dividends or distributions paid in
shares of Common Stock or such other junior ranking stock), until full
cumulative dividends on the Series B Preferred Stock are declared and paid or
set apart for payment.

     (2)  Redemption. Shares of Series B Preferred Stock shall be redeemable, at
the option of the Corporation, in whole or in part at any time or from time to
time after June 30, 1993 at the stated value per share of Series B Preferred
Stock, plus an amount equal to accrued and unpaid dividends (whether or not
declared) to the date fixed for redemption.

     In case of the redemption of only part of the Series B Preferred Stock at
the time outstanding, such redemption shall be made pro rata, provided, however,
that the corporation shall not be required to effect the redemption in any
manner that results in additional fractional shares being outstanding; if full
cumulative dividends shall not have been paid or declared and set apart for
payment for all semiannual dividends to and including the last dividend payment
date prior to the date fixed for redemption, the Corporation shall not call for
redemption any shares of Series B Preferred Stock unless all such shares then
outstanding are called for simultaneous redemption.

     Notice of any proposed redemption of Series B Preferred Stock shall be
given by the Corporation not less than 30




                                      -3-
<PAGE>   32
days nor more than 60 days prior to the date fixed for such redemption to each
holder of record of the shares to be redeemed at his address appearing on the
books of the Corporation. Notice of redemption shall be deemed to have been
given when deposited in the United States mails, by registered or certified mail
or delivered to a courier service, whether or not such notice is actually
received. If on or before the redemption date specified in such notice all funds
necessary for such redemption shall have been set aside by the Corporation,
separate and apart from its other funds, in trust for the pro rata benefit of
the holders of the shares so called for redemption, so as to be and continue to
be available therefor, then from and after the date of redemption so designated,
notwithstanding that any certificate representing shares of Series B Preferred
Stock so called for redemption shall not have been surrendered for cancellation,
the shares represented thereby shall no longer be deemed outstanding, the right
to receive dividends thereon shall cease to accrue and all rights with respect
to such shares of Series B Preferred Stock so called for redemption shall
forthwith at the close of business on such redemption date cease and terminate,
except only the right of the holders thereof to receive the redemption price of
such shares so to be redeemed plus an amount equal to accrued and unpaid
dividends (whether or not declared) up to the date fixed for redemption, but
without interest thereon.

     Any moneys so set aside by the Corporation and unclaimed at the end of
three years form the date fixed for redemption shall revert to the general funds
of the Corporation.

     The Corporation may, however, prior to the redemption date specified in the
notice of redemption, deposit in trust for the account of the holders of the
shares of Series B Preferred Stock to be redeemed, with a bank or trust company
in good standing organized under the laws of the United States of America or of
any state thereof, having its principal office located in the continental United
States, and having a capital, surplus and undivided profits aggregating at least
$50 million, designated in such notice of redemption, all funds necessary for
such redemption (including accrued and unpaid dividends up to the date fixed for
redemption), together with irrevocable written instructions authorizing such
bank or trust company, on behalf and at the expense of the Corporation, to cause
the notice of redemption to be mailed as herein provided at least 30 days but
not more than 60 days prior to the redemption date and to include in said notice
of redemption a statement that all




                                      -4-
<PAGE>   33
funds necessary for such redemption have been so deposited in trust and are 
immediately available, and on the redemption date, notwithstanding that any 
certificate representing shares of Series B Preferred Stock called for 
redemption shall not have been surrendered for cancellation, all shares of 
Series B Preferred Stock with respect to which such deposit shall have been 
made and which are outstanding on such redemption date shall no longer be 
deemed to be outstanding and all rights with respect to such shares of Series B 
Preferred Stock shall forthwith at the close of business on such redemption date
cease and terminate, except only the right of the holders thereof to receive 
from such bank or trust company, at any time after the redemption date, the 
redemption price of such shares so to be redeemed plus accrued and unpaid 
dividends up to the date fixed for redemption. In the event the holder of any 
such shares of Series B Preferred Stock shall not, within three years after the 
redemption date, claim the amount deposited for the redemption thereof, the 
depositary shall, upon the request of the Corporation expressed in a resolution 
of its Board of Directors, pay over to the Corporation such unclaimed amount 
after which time the holders of the shares so called for redemption shall look
only to the Corporation for the payment thereof.

     If any shares of Series B Preferred Stock called for redemption are not 
issued and outstanding as of the date fixed for redemption, the amount set 
aside or deposited for the redemption thereof shall revert to or be paid over 
to the Corporation.

     Any shares of Series B Preferred Stock which are redeemed or otherwise 
purchased or acquired by the Corporation or any subsidiary thereof shall be 
cancelled. The number of shares of Series B Preferred Stock shall be reduced by 
the number of shares so cancelled and such cancelled shares shall be restored 
to the status of authorized but unissued shares of Preferred Stock that are 
undesignated as to series. For the purposes of this paragraph, a subsidiary 
means a corporation of which a majority of the capital stock having voting 
power under ordinary circumstances to elect a majority of the board of 
directors is owned by (a) the Corporation, (b) the Corporation and one or more 
of its subsidiaries or (c) one or more of the Corporation's subsidiaries.

     (3) Regarding Voting Rights. Each share of Series B Preferred Stock shall 
entitle the holder thereof to one vote for each share held and, except as 
provided herein or by


                                      -5-
<PAGE>   34
law, the Series B Preferred Stock and the Common Stock (and any other capital 
stock of the Corporation at any time entitled to vote) shall vote together as a 
single class.

     In addition to any provisions herein and any requirement of law, the 
Series B Preferred Stock shall vote as a single class with respect to any 
proposal (a) to change the dividend rate, liquidation preference, redemption 
price, voting rights or conversion rights of the shares of the Series B 
Preferred Stock or to increase the number of authorized shares of Series B 
Preferred Stock; (b) to increase the authorized amount, or authorize, issue, 
create or sell any shares of any class (or any series of any class) of capital 
stock of the Corporation that ranks prior to the Series B Preferred Stock as to 
dividends or distribution of assets upon liquidation; and (c) for the 
alteration, change or modification of the rights set forth in this paragraph. 
The affirmative vote of the holders of two-thirds of the outstanding shares of 
Series B Preferred Stock shall be required to take action with respect to any 
matter described in clauses (a) through (c) of the foregoing sentence.

     Unless the vote of a larger percentage is required by law or the Restated 
Articles of Incorporation, the affirmative vote of the holders of a majority of 
the outstanding shares of Series B Preferred Stock shall be sufficient to take 
any action as to which a class vote of the holders of the Series B Preferred 
Stock is required by law or the Restated Articles of Incorporation.

     Whenever, at any time, dividends payable on the Series B Preferred Stock 
shall be in arrears for more than 180 calendar days, the holders of the Series 
B Preferred Stock shall have the exclusive right, voting separately as a class, 
to elect by a majority of the votes cast two directors of the Corporation, who 
shall be a Class II director and a Class III director, respectively, (i) at the 
Corporation's next annual meeting of shareholders, (ii) at a special meeting 
held in place thereof, (iii) at a special meeting of the holders of shares of 
the Series B Preferred Stock called by the Secretary of the Corporation upon 
the written request of the holders of record of 25% or more of the total number 
of shares of Series B Preferred Stock then outstanding, to be held within 30 
days after delivery of such request, or (iv) by written consent of the holders 
of a majority of the issued and outstanding shares of Series B Preferred Stock 
in lieu thereof, and at each meeting of shareholders thereafter at which 
directors shall be elected until such rights shall terminate as hereinafter 
provided.


                                      -6-
<PAGE>   35
The Board of Directors of the Corporation hereby unanimously directs the
Secretary of the Corporation to give notice of any special meeting of the
shareholders of the Corporation required from time to time by the provisions of
this Paragraph (3), in the manner prescribed by the Bylaws of the Corporation.
At elections for such directors, each holder of the Series B Preferred Stock
shall be entitled to one vote for each share held. Upon the vesting of such
voting right in the holders of the Series B Preferred Stock, the maximum
authorized number of members of the Board of Directors shall automatically be
increased by two and the two vacancies so created shall be filled by vote of the
holders of the Series B Preferred Stock as hereinabove set forth. The right of
the holders of the Series B Preferred Stock, voting separately as a class, to
elect members of the Board of Directors of the Corporation as aforesaid shall
continue until such time as all dividends accumulated on the Series B Preferred
Stock shall have been paid in full, at which time such right shall terminate,
except as by law expressly provided, subject to revesting in the event of each
and every subsequent default of the character above mentioned. Upon any
termination of the right of the holders of the Series B Preferred Stock to vote
for directors as herein provided, the term of office of all directors then in
office elected by such series voting as a class shall terminate immediately. If
the office of any director elected by the holders of the Series B Preferred
Stock becomes vacant by reason of death, resignation, retirement,
disqualification, removal from office, or otherwise, the remaining director
elected by the holders of Series B Preferred Stock voting as a class may choose
a successor who shall hold office for the unexpired term in respect of which
such vacancy occurred. Whenever the special voting powers vested in the holders
of the Series B Preferred Stock shall have expired, the number of directors
shall become such number as may be provided for in the ByLaws, or resolution of
the Board of Directors thereunder, irrespective of any increase made pursuant to
the provisions of this Paragraph (3).

     (4)  Priority in Event of Dissolution. In the event of any liquidation, 
dissolution or winding up of the affairs of the Corporation, after payment or 
provision for payment of the debts and other liabilities of the Corporation 
(including any liquidation preferences payable in respect of the Corporation's 
Series A Preferred Stock and any other capital stock of the Corporation 
ranking senior to the Series B Preferred Stock as to assets), the holders of 
the Series B Preferred Stock shall be entitled to receive, out of the remaining 
net assets of the Corporation, $50.00 in



                                      -7-
<PAGE>   36
cash for each share of Series B Preferred Stock, plus an amount equal to all 
dividends accrued and unpaid on each such share (whether or not declared) up to 
the date fixed for distribution, before any distribution shall be made to the 
holders of the Common Stock of the Corporation or any other stock of the 
Corporation ranking junior to the Series B Preferred Stock as to assets. If 
upon any liquidation, dissolution or winding up of the affairs of the 
Corporation, the assets distributable among the holders of the Series B 
Preferred Stock (and any other capital stock of the Corporation ranking on a 
parity with the Series B Preferred Stock as to assets) shall be insufficient to 
permit the payment in full to the holders of all shares of such Series B 
Preferred Stock (and any other capital stock of the Corporation ranking on a 
parity with the Series B Preferred Stock as to assets) of all preferential 
amounts payable to all such holders, then the entire assets of the Corporation 
thus distributable shall be distributed ratably among the holders of the Series 
B Preferred Stock (and any other capital stock of the Corporation ranking on a 
parity with the Series B Preferred Stock as to assets) in proportion to the 
respective amounts that would be payable per share if such assets were 
sufficient to permit payment in full.

     (5)  Conversion.    (a)  Subject to and upon compliance with the 
provisions herein, at the option of the holder, shares of Series B Preferred 
Stock may, at any time be converted into fully paid and nonassessable shares of 
Common Stock at the rate of 1.25 shares of Common Stock for each share of 
Series B Preferred Stock to be converted (subject to adjustment as hereinafter 
provided) ("conversion rate"); provided, however, that if the Corporation shall 
have given notice of redemption of any shares of Series B Preferred Stock 
pursuant to Paragraph (2) above, the right to convert such shares shall 
terminate at 5:00 p.m., Houston, Texas time, on the date fixed for redemption 
(unless the Corporation shall default in the payment due upon redemption in 
which case such conversion rights shall not expire). The result obtained by 
dividing $50.00 by the conversion rate in effect from time to time is herein 
referred to as the "conversion price."  Whenever the conversion price is 
adjusted pursuant to the provisions of Subparagraph (d) below, the conversion 
rate shall be redetermined by dividing $50.00 by the then adjusted conversion 
price. The conversion rate and the conversion price in effect from time to time 
shall be calculated to four decimal places and rounded to the nearer thousandth.

     (b)  In order to exercise the right to convert, the holder of any shares 
of Series B Preferred Stock to be


                                      -8-
<PAGE>   37
converted shall surrender the certificate representing such Series B Preferred
Stock, accompanied (if so required by the Corporation) by the proper instrument
or instruments of transfer, in form satisfactory to the Corporation, duly
executed by the registered holder thereof or by his attorney duly authorized in
writing, to the Corporation at its principal executive office, and shall give
written notice to the Corporation at such office that the holder elects to
convert such Series B Preferred Stock. No payment or adjustment shall be made
upon any conversion on account of regular cash dividends declared or accrued on
the Common Stock or the Series B Preferred Stock surrendered for conversion.
Series B Preferred Stock shall be deemed to have been converted immediately
prior to the close of business on the later of (i) the date on which all
applicable waiting periods, if any, under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and the rules and regulations thereunder have expired
or been terminated and (ii) the date of the giving of such notice and of the
surrender of such certificates for conversion in accordance with the foregoing
provisions, and at such time the rights of the holder of such Series B Preferred
Stock as such holder shall cease, and the holder thereof shall be treated for
all purposes as the record holder of Common Stock from and after such time. As
promptly as practicable after receipt of such notice, the surrender of such
certificates and expiration or termination of any applicable waiting period as
aforesaid, the Corporation shall issue and deliver at such office a certificate
or certificates for the number of full shares of Common Stock issuable upon
conversion.

     (c)  No fractional share of Common Stock shall be issued upon conversion 
of Series B Preferred Stock. Instead of any fractional share of Common Stock 
which would otherwise be issuable upon conversion of any Series B Preferred 
Stock, the Corporation shall pay a cash adjustment equal to such fraction 
multiplied by the Price per share of the Common Stock on the trading day next 
preceding the date of conversion. In determining the number of shares of Common 
Stock and the payment, if any, in lieu of fractional shares that a holder of 
Series B Preferred Stock shall receive, the total number of shares of Series B 
Preferred Stock surrendered for conversion by such holder shall be aggregated.

     (d)  The number and kind of securities issuable upon the conversion of the 
Series B Preferred Stock shall be subject to adjustment from time to time, upon 
the happening of certain events occurring after the date of these Articles of 
Amendment as follows:


                                      -9-
<PAGE>   38
     (i) In case of any reclassification or change of outstanding securities
issuable upon exercise of the conversion rights (other than a change in par
value, or from par value to no par value, or from no par value (to par value to
par value or as a result of a subdivision or combination) or in case of any
consolidation or as a result of a subdivision or combination), or in case of any
consolidation or merger of the Corporation with or into another corporation
(other than a merger with another corporation in which the Corporation is the
surviving Corporation and which does not result in any reclassification or
change -- other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a subdivision or
combination -- of outstanding securities issuable upon exercise of these
conversion rights) or in the case of a sale or conveyance in a single
transaction or in a series of related transactions with the same purchaser of
all or substantially all the assets of the Corporation as an entirety, the
holders of the Series B Preferred Stock shall have, and the Corporation, or such
successor corporation or purchaser, shall covenant in the constituent documents
effecting any of the foregoing transactions that the holders of the Series B
Preferred Stock do have, the right to obtain upon the exercise of these
conversion rights, in lieu of each share of Common Stock theretofore issuable
upon exercise of these conversion rights, the kind and amount of shares of
stock, other securities, money and property receivable upon such
reclassification, change, consolidation, merger, or conveyance or sale of assets
by a holder of one share of Common Stock issuable upon exercise of these
conversion rights as if they had been exercised immediately prior to such
reclassification, change, consolidation, merger, or conveyance or sale of
assets. The constituent documents effecting any reclassification, change,
consolidation, merger or conveyance or sale of assets shall provide for any
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided in this Subparagraph (d).  The provisions of this
Subparagraph (d)(i) shall similarly apply to successive reclassifications,
changes, consolidations, mergers or conveyances or sales of assets.

     (ii) If the Corporation at any time shall subdivide or combine its Common
Stock, the conversion price shall be proportionately reduced, in case of
subdivision of shares, as at the effective date of such subdivision, or if the
Corporation shall take a record of holders of its Common Stock for the purpose
of so



                                      -10-
<PAGE>   39
subdividing, as at such record date, whichever is earlier, or shall be
proportionately increased, in the case of combination of shares, as at the
effective date of such combination or, if the Corporation shall take a record of
holders of its Common Stock for the purpose of so combining, as at such record
date, whichever is earlier.

     (iii) If the Corporation shall:

          (A) Pay to any holders of securities of the Corporation a dividend
     payable in, or make any other distribution of, Common Stock, the conversion
     price shall be adjusted, as at the date the Corporation shall take a record
     of the holders of its Common Stock for the purpose of receiving such
     dividend or other distribution (or if no such record is taken, as at the
     date of such payment or other distribution), to that price determined by
     multiplying the conversion price in effect immediately prior to such record
     date (or if no such record is taken, then immediately prior to such payment
     or other distribution) by a fraction (1) the numerator of which shall be
     the total number of shares of Common Stock outstanding immediately prior to
     such dividend or distribution, and (2) the denominator of which shall be
     the total number of shares of Common Stock outstanding immediately after
     such dividend or distribution (plus in the event that the Corporation paid
     cash for fractional shares, the number of additional shares which would
     have been outstanding had the Corporation issued fractional shares in
     connection with said dividend, except to the extent such payment of cash is
     treated as a dividend payable out of earnings or surplus legally available
     for the payment of dividends under the laws of the State of Louisiana); or

          (B) Make a distribution of its securities (other than Common Stock
     Equivalents as defined below) or assets to the holders of its Common Stock
     other than dividends payable in Common Stock or cash dividends from
     retained earnings of the Corporation, the Corporation shall reserve and
     shall deposit in trust, with a bank or trust company in good standing
     organized under the laws of the United States of America or any state
     thereof, having it principal office located in


                                      -11-
<PAGE>   40
     the United States, and having capital, surplus and undivided profits
     aggregating at least $50 million, for distribution to the holders of the
     Series B Preferred Stock who shall thereafter elect to convert shares of
     Series B Preferred Stock into Common Stock (or for release to the
     Corporation, as provided below) the amount and kind of securities or assets
     which such holders would have received if all such holders had, immediately
     prior to the record date for the distribution of securities or assets,
     converted such shares of Series B Preferred Stock into Common Stock. Any
     such holder converting shares of Series B Preferred Stock into Common Stock
     will receive from such trust upon such conversion, in addition to the
     shares of Common Stock to which such holder is entitled, a pro rata portion
     of the assets and securities then held in such trust. If after any such
     assets are placed in trust the shares of Series B Preferred Stock are
     exchanged for Debentures pursuant to Paragraph (6), (such assets shall then
     be held by the trustee for distribution to the holders of the Debentures
     (as defined in Paragraph (6)) who shall thereafter elect to convert such
     Debentures into Common Stock (or for release to the Corporation, as
     provided below). To the extent that any shares of Series B Preferred Stock
     are redeemed or cancelled, a proportionate portion of such assets held in
     trust shall be released to the Corporation and shall no longer be subject
     to distribution to the holders of Series B Preferred Stock upon conversion
     thereof into Common Stock. Any taxes or expenses related to the assets so
     held in trust, the income therefrom, the creation or administration of the
     trust, the reasonable compensation of the trustee, or related matters shall
     be paid by the trustee from the trust estate.

     (iv) If the Corporation shall issue any additional shares of Common Stock
(otherwise than as provided in the foregoing Subparagraphs (i) through (iii)
above) at a price per share less than the average Price per share of Common
Stock for the 20 trading days immediately preceding the date of the
authorization of such issuance by the Corporation's Board of Directors (the
"Market Price") then the conversion price upon each such issuance shall be
adjusted to that price



                                      -12-
<PAGE>   41
determined by multiplying the conversion price by a fraction:

          (A) the numerator of which shall be (1) the sum of (i) the number of
     shares of Common Stock outstanding immediately prior to the issuance of
     such additional shares of Common Stock multiplied by the Market Price, and
     (ii) the consideration, if any, received and deemed received by the
     Corporation upon the issuance of such additional shares of Common Stock;
     divided by (2) the total number of shares of Common Stock outstanding
     immediately after the issuance of such additional shares of Common Stock,
     and

          (B) the denominator of which shall be the Market Price.

     No adjustment of the conversion price shall be made in an amount less than
$.05 per share, but any such lesser adjustment shall be carried forward and
shall be made at the time together with the next subsequent adjustment which,
together with any adjustments so carried forward, shall amount to $.05 per share
or more. Further, no adjustments of the conversion price shall be made under
this Subparagraph (d)(iv) upon the issuance of any additional shares of Common
Stock that (x) are issued pursuant to thrift plans, stock purchase plans, stock
bonus plans, stock option plans, employee stock ownership plans and other
incentive or profit sharing arrangements for the benefit of employees, provided
such plans or arrangements have been approved by a majority of either the
disinterested members of the Board of Directors of the Corporation or the
Corporation's shareholders ("Employee Benefit Plans") or (y) are issued pursuant
to any Common Stock Equivalent (as defined in Subparagraph (d)(v) below), if
upon the issuance of any such Common Stock Equivalent, any such adjustments
shall previously have been made pursuant to Subparagraph (d)(v) hereof or if no
adjustment was required pursuant to Subparagraph (d)(v)hereof.

     The Price per share of Common Stock on any day means the average (mean) of
the reported "high" and "low" sales prices for such shares as reported in The
Wall Street Journal's NYSE-Composite Transactions listing for such day
(corrected for obvious typographical errors), or if such shares are not reported
in such


                                      -13-
<PAGE>   42
listing, then the average of the reported "high" and "low" sales prices on the
largest national securities exchange  (based on the aggregate dollar value of
securities listed) on which such shares are listed or traded, or if such shares
are not listed or traded on any national securities exchange, then the average
of the reported "high" and "low" sales prices for such shares in the
over-the-counter market, as reported on the National Association of Securities
Dealers Automated Quotations System, or, if such prices shall not be reported
thereon, the average of the closing bid and asked prices so reported, or, if
such prices shall not be reported, then the average closing bid and asked prices
reported by the National Quotation Bureau Incorporated, or, in all other cases,
the value established by the Board of Directors of the Corporation in good
faith. The "average" Price per share of the Common Stock for any period shall be
determined by dividing the sum of the Prices determined for the individual days
in such period by the number of days in such period.

     (v) In case the Corporation shall issue any security or evidence of
indebtedness which is convertible into or exchangeable for Common Stock
("Convertible Security"), or any warrant, option or other right to subscribe for
or purchase Common Stock or any Convertible Security, other than pursuant to
Employee Benefit Plans, (together with Convertible Securities, "Common Stock
Equivalent"), or if, after any such issuance, the price per share for which
additional shares of Common Stock may be issuable thereunder is amended, then
the conversion price upon each such issuance or amendment shall be adjusted as
provided in Subparagraph (d)(iv) hereof on the basis that (i) the maximum number
of additional shares of Common Stock issuable pursuant to all such Common Stock
Equivalents shall be deemed to have been issued as of the earlier of (a) the
date on which the Corporation shall enter into a firm contract for the issuance
of such Common Stock Equivalent, or (b) the date of actual issuance of such
Common Stock Equivalent; and (ii) the aggregate consideration for such maximum
number of additional shares of Common Stock shall be deemed to be the minimum
consideration received and receivable by the Corporation for the issuance of
such additional shares of Common Stock pursuant to such Common Stock Equivalent;
provided, however, that no adjustment shall be made pursuant to this
Subparagraph (d)(v) unless the consideration


                                      -14-
<PAGE>   43
received and receivable by the Corporation per share of Common Stock for the
issuance of such additional shares of Common Stock pursuant to such Common Stock
Equivalent is less than the Market Price.  No adjustment of the conversion price
shall be made under this Subparagraph upon the issuance of any Convertible
Security which is issued pursuant to the exercise of any warrants or other
subscription or purchase rights therefor, if any adjustment shall previously
have been made in the conversion price then in effect upon the issuance of such
warrants or other rights pursuant to this Subparagraph (d)(v).

     (vi) The following provisions shall be applicable to making of adjustments 
in the conversion price hereinbefore provided in this Subparagraph (d):

          (A) The consideration received by the Corporation shall be deemed to 
     be the following: to the extent that any additional shares of Common Stock
     or any Common Stock Equivalents shall be issued for cash consideration, the
     consideration received by the Corporation therefor, or, if such additional
     shares of Common Stock or Common Stock Equivalents are offered by the
     Corporation for subscription, the subscription price, or, if such
     additional shares of Common Stock or Common Stock Equivalents are sold to
     underwriters or dealers for public offering without a subscription
     offering, the initial public offering price, in any such case excluding any
     amounts paid or receivable for accrued interest or accrued dividends and
     without deduction of any compensation, discounts, commissions or expenses
     paid or incurred by the Corporation for and in the underwriting of, or
     otherwise in connection with, the issue thereof; to the extent that such
     issuance shall be for a consideration other than cash, then, except as
     herein otherwise expressly provided, the fair market value of such
     consideration at the time of such issuance as determined in good faith by
     the Corporation's Board of Directors. The consideration for any additional
     shares of Common Stock issuable pursuant to any Common Stock Equivalents
     shall be the consideration received by the Corporation for issuing such
     Common Stock Equivalents, plus the additional consideration payable to the
     Corporation upon the exercise,
<PAGE>   44
conversion or exchange of such Common Stock Equivalents. In case of the 
issuance at any time of any additional shares of Common Stock or Common Stock 
Equivalents in payment or satisfaction of any dividend upon any class of stock 
other than Common Stock, the Corporation shall be deemed to have received for 
such additional shares of Common Stock or Common Stock Equivalents a 
consideration equal to the amount of such dividend so paid or satisfied. In any 
case in which the consideration to be received or paid shall be other than 
cash, the Board of Directors of the Corporation shall notify promptly each 
holder of the Series B Preferred Stock of its determination of the fair market 
value of such consideration.

     (B) Upon the expiration of the right to convert, exchange or exercise any 
Common Stock Equivalent the issuance of which effected an adjustment in the 
conversion price, if any such Common Stock Equivalent shall not have been 
converted, exercised or exchanged, the number of shares of Common Stock deemed 
to be issued and outstanding by reason of the fact that they were issuable upon 
conversion, exchange or exercise of any such Common Stock Equivalent shall no 
longer be computed as set forth above, and the conversion price shall forthwith 
be readjusted and thereafter be the price which it would have been (but 
reflecting any other adjustments in the conversion price made pursuant to the 
provisions of Subparagraph (d)(iv) after the issuance of such Common Stock 
Equivalent) had the adjustment of the conversion price made upon the issuance 
or sale of such Common Stock Equivalent been made on the basis of the issuance 
only of the number of additional shares of Common Stock actually issued upon 
exercise, conversion or exchange of such Common Stock Equivalent and thereupon 
only the number of additional shares of Common Stock actually so issued shall 
be deemed to have been issued and only the consideration actually received by 
the Corporation (computed as in Subparagraph (A) of this Subparagraph (d)(vi)) 
shall be deemed to have been received by the Corporation.

     (C) The number of shares of Common Stock at any time outstanding shall not 
include any shares thereof then directly or indirectly owned or held


                                      -16-
<PAGE>   45
         by or for the account of the Corporation or its subsidiaries.

     (e) Whenever the conversion price and the conversion rate are required to 
be adjusted as provided herein, the Corporation shall forthwith compute the 
adjusted conversion price and the adjusted conversion rate and shall prepare a 
certificate setting forth such adjusted conversion price and adjusted 
conversion rate and showing in detail the facts upon which such adjustment is 
based. A copy of such certificate shall forthwith be filed with the transfer 
agent or agents for the Series B Preferred Stock (if any) and for the Common 
Stock; and thereafter, until further adjusted, the adjusted conversion price 
and the adjusted conversion rate shall be as set forth in such certificate, 
provided that the computation of such adjusted conversion price and such 
adjusted conversion rate shall be reviewed at least annually by the independent 
public accountants regularly employed by the Corporation and said accountants 
shall file a corrected certificate, if required, with such transfer agent or 
agents. The Corporation shall mail or cause to be mailed to the holders of 
Series B Preferred Stock at the time of each semiannual dividend payment, a 
statement setting forth the adjustments, if any, made in the applicable 
conversion price and conversion rate and not theretofore reported to such 
holders, and the reasons for such adjustment.

     (f) The Corporation will at all times reserve and keep available, out of 
its authorized and unissued Common Stock solely for the purpose of issuance 
upon the conversion of the Series B Preferred Stock as herein provided, free 
from preemptive and other subscription rights, such number of shares of Common 
Stock as shall then be issuable upon the conversion of all outstanding Series B 
Preferred Stock. The Corporation shall ensure that all shares of Common Stock 
which shall be so issuable shall upon issue be duly and validly issued and 
fully paid and nonassessable.

     (g) If any shares of Common Stock required to be reserved for the purposes 
of conversion of Series B Preferred Stock hereunder require registration with or
approval of any governmental authority under any federal or state law, or
listing upon any national securities exchange, before such shares may be issued
upon conversion, the Corporation will in good faith and as expeditiously as
possible endeavor to cause such shares to be duly registered, approved or
listed, as the case may be.



                                      -17-
<PAGE>   46
     (h) The issuance of certificates for shares of Common Stock upon the 
conversion of Series B Preferred Stock shall be made without charge to the 
holders thereof for any transfer or similar taxes that may be payable in 
respect of the issue, delivery or acquisition of such certificates. Such 
certificates shall be issued in the respective names of the holders of the 
Series B Preferred Stock converted.

     (6) Exchange. The Series B Preferred Stock outstanding is exchangeable in 
whole at the option of the Corporation at any time after July 25, 1990 for the 
Corporation's 7 1/3% Convertible Subordinated Debentures due 2013 (the 
"Debentures"). Holders of outstanding shares of Series B Preferred Stock will 
be entitled to receive $50.00 principal amount of Debentures plus an amount in 
cash equal to accrued and unpaid dividends (whether or not declared) to the 
date fixed for exchange, in exchange for each share of Series B Preferred Stock 
held by them at the time of exchange; provided that the Debentures will be 
issuable in denominations of $1,000 and integral multiples thereof and an 
amount in cash shall be paid to such holders for any excess principal amount 
otherwise issuable. The Corporation will mail to each record holder of the 
Series B Preferred Stock written notice of its intention to exchange not less 
than 30 nor more than 60 days prior to the date fixed for exchange. The notice 
shall specify the effective date of the exchange, the place where certificates 
for shares of Series B Preferred Stock are to be surrendered for Debentures and 
state that dividends on Series B Preferred Stock will cease to accrue on such 
date fixed for exchange. Prior to giving notice of intention to exchange, the 
Corporation shall execute and deliver with a bank or trust company selected by 
the Corporation an Indenture substantially in the form attached as an exhibit 
to the Securities Purchase Agreement dated as of April 18, 1988 among the
Corporation and the purchasers named therein, with such changes as may be
required by law, stock exchange rule or as may be necessary to qualify such
Indenture under the Trust Indenture Act of 1939. The Corporation will cause the
Debentures to be authenticated and such accrued and unpaid dividends to be set
aside, separate and apart from the other funds of the Corporation, in trust for
the benefit of the holders of the Series B Preferred Stock, for payment on the
date on which the exchange is effective; at such time the rights of the holders
of the Series B Preferred stock as shareholders of the Company shall cease and
the shares of Series B Preferred Stock shall no longer be deemed outstanding and
shall represent only the right to receive the Debentures and such accrued and
unpaid dividends but without interest thereon.




                                      -18-
<PAGE>   47
Any moneys set aside by the Corporation and unclaimed at the end of three years 
from the date fixed for exchange shall revert to the general funds of the 
Corporation. Notwithstanding the foregoing, if notice of exchange has been 
given pursuant to this Paragraph (6) and any holder of shares of Series B 
Preferred Stock shall, prior to the close of business on the date fixed for 
exchange, give written notice to the Corporation pursuant to Paragraph (5) of 
the conversion of any or all of the shares to be exchanged held by such holder 
(accompanied by a certificate or certificates for such shares, duly endorsed or 
assigned to the Corporation), then such exchange shall not become effective as 
to such shares to be converted and such conversion shall become effective as 
provided in Paragraph (5). The Debentures and such accrued and unpaid dividends 
will be delivered to the persons entitled thereto upon surrender to the 
Corporation or its agent appointed for that purpose of the certificates for the 
share of Series B Preferred Stock being exchanged therefor.

     (7) Sinking Fund. The Series B Preferred Stock shall not be entitled to 
any mandatory redemption or prepayment (except on liquidation, dissolution or 
winding up of the affairs of the Corporation) or to the benefit of any sinking 
fund.

     (8) Definition. If the day upon which any payment is to be made or any 
other action is to be taken or any event is scheduled to occur pursuant to the 
terms of these Articles of Amendment is not a business day, the payment shall 
be made or the other action shall be taken on the next succeeding business day. 
A "business day" is defined as a day in the City of Houston, County of Harris, 
Texas, that is not a legal holiday or a day on which banking institutions are 
authorized or obligated by law to close.

     (9) Notice. Except as otherwise provided herein, any notice, demand or 
other communication shall be deemed given and received as of the date of 
delivery in person or receipt set forth on the return receipt. The inability to 
deliver because of rejection or other refusal to accept any notice, demand or 
other communication, shall be deemed to be receipt of such notice, demand or 
other communication as of the date of such inability to deliver or rejection or 
refusal to accept.

     2. Paragraph D. of Article III of the Restated Articles of Incorporation 
is designated as paragraph E.

     BE IT KNOWN, that on this 2nd day of December, 1987, 
     BEFORE ME, Margaret Bassett, a Notary Public, duly commissioned and
qualified, in and for the County of Harris, and in the presence of the witnesses
hereinafter named and undersigned:

                          PERSONALLY CAME AND APPEARED:

     Clarence C. Comer and Wendell E. Phillips, II, appearing herein and acting
for Southdown, Inc. (of which corporation they are, respectively, President and
Secretary), a corporation organized and existing under the laws of the State of
Louisiana, domiciled in the Parish of Orleans, State of Louisiana, organized by
Articles of Incorporation executed and acknowledged on April 4, 1930, and
recorded on April 5, 1930 in the records of the Recorder of the Parish of
Orleans and on April 7, 1930, in the Record of Charters Book 130, who declared
that pursuant to resolution of the shareholders of the corporation, adopted at a
special meeting of shareholders of the corporation held on December 2, 1987, at
2:00 p.m., at the offices of the corporation, 1200 Smith Street, Suite 2200,
Houston, Texas, they now appear for the purpose of executing this act of
amendment and putting into authentic form the amendment so agreed to by the
vote of the shareholders of said corporation.

     AND THE SAID APPEARERS further declared that by vote of the shareholders of
the corporation, it was resolved that the Articles of Incorporated of the
corporation be amended by adding a new Article XIII as follows:

          "No director or officer of this corporation shall be personally liable
     to this corporation or its shareholders for monetary damages for breach of
     fiduciary duty as a director or officer, except for liability (i) for
     breach of the director's or officer's duty of loyalty to this corporation
     or its shareholders, (ii) for acts or omissions not in good faith or which
     involve intentional misconduct or a knowing violation of law, (iii) under
     Section 92(D) of the Louisiana Business Corporation Law, or (iv) for any
     transaction from which the director or officer derived an improper personal
     benefit. If the Louisiana

<PAGE>   52
     Business Corporation Law is hereafter amended to authorize corporate action
     further limiting or eliminating the personal liability of directors or
     officers, then the liability of each director and officer of this
     corporation shall be limited or eliminated to the full extent permitted by
     the Louisiana Business Corporation Law as so amended from time to time.
     Neither the amendment nor repeal of this Article, nor the adoption of any
     provision of this corporation's Articles of Incorporation inconsistent with
     this Article, shall eliminate or reduce the effect of this Article, in
     respect of any matter occurring, or any cause of action, suit or claim
     that, but for this Article, would accrue or arise, prior to such amendment,
     repeal or adoption of any inconsistent provision."

     AND THE SAID APPEARERS further declared that 5,615,745 of the shares of the
corporation were represented at said meeting and that 5,214,882 shares voted for
the said amendment and that 400,863 shares voted against the said amendment.

     AND THE SAID APPEARERS having requested me, Notary, to note said amendment
in authentic form, I do by these presents receive said amendment in the form of
this public act to the end that said amendment may be promulgated and recorded
and thus be read into the original Restated Articles of Incorporation of
Southdown, Inc., as hereinabove set forth.

     THUS DONE AND PASSED, in my office at Houston, Texas, on the day, month and

were restated pursuant to Restated Articles of Incorporation effective September
15, 1983, who declared that pursuant to Sections 24B(6) and 33A of the Louisiana
Business Corporation Law, Article IIIB of the Restated Articles of Incorporation
of the Corporation, and resolutions of the Board of Directors of the Corporation
adopted at a special meeting of the Board of Directors of the Corporation held
on April 7, 1987, they now appear for the purpose of executing this act of
amendment and putting into authentic form the amendment so adopted by the Board
of Directors of said Corporation.

     AND THE SAID APPEARERS further declare that by unanimous vote of the Board 
of Directors of said Corporation, it was resolved that Article III of the 
Restated Articles of Incorporation of Southdown, Inc. be further amended as 
follows:

     1.   There is added as a new paragraph C of Article III the following:

          C. Of the aforesaid 5,000,000 shares of Preferred Stock, 999,999 
shares shall constitute a separate series of preferred shares designated 
"Preferred Stock, $1.40 Cumulative Convertible Series A" (hereinafter called 
the "Series A          
<PAGE>   56
Preferred Stock"), which shall have a stated value of $20.00 per share. The
preferences, limitations and relative rights of the Series A Preferred Stock are
as follows:

                                PREFERRED STOCK,
                     $1.40 CUMULATIVE CONVERTIBLE SERIES A

         (1) Dividends. The holders of the Series A Preferred Stock shall be
entitled to receive, when and as declared by the Board of Directors out of the
funds of the Corporation legally available therefor and in preference to the
holders of the Common Stock of the Corporation and any other capital stock of
the Corporation ranking junior to the Series A Preferred Stock as to dividends,
cumulative preferential dividends per share of Series A Preferred Stock in cash
at the rate per annum of $1.40 and no more. Dividends on the Series A Preferred
Stock will be cumulative, will accrue from the date of original issuance and
will be paid (when and as declared by the Board of Directors of the Corporation)
in cash quarterly, in arrears, on the last day of each March, June, September
and December, commencing on the first such date to occur after the date of
original issuance of the Series A Preferred Stock. Each dividend on the Series A
Preferred Stock shall be paid to the holders of record of shares of the Series A
Preferred Stock as they appear on the stock register of the Corporation on such
record date, not exceeding 30 days preceding the payment date thereof, as shall
be fixed by the Board of Directors of the Corporation. Dividends on account of
arrears for any past dividend periods may be declared and paid at any time,
without reference to any regular dividend payment date, to holders of record on
such date, not exceeding 45 days preceding the payment date thereof, as may be
fixed by the Board of Directors of the Corporation. No dividend may be declared
on any other series or class of stock ranking on a parity with the Series A
Preferred Stock as to dividends in respect of any quarterly dividend period,
unless there shall also be or have been declared on the Series A Preferred Stock
like dividends for all quarters at the dividend rates fixed therefor. In the
event that full cumulative dividends on the Series A Preferred Stock have not
been declared and paid or set apart for payment, the Corporation may not declare
or pay or set apart for payment any dividends or make any other distributions
on, or make any payment on account of the purchase, redemption or retirement of,
the Common Stock or any other stock of the Corporation ranking as to dividends
or distributions of assets on liquidation, dissolution or winding up of the
Corporation junior to the Series A Preferred Stock (other than, in the case of
dividends or



                                      -2-
<PAGE>   57
distributions, dividends or distributions paid in shares of Common Stock or such
other junior ranking stock), until full cumulative dividends on the Series A
Preferred Stock are declared and paid or set apart for payment.

     (2)  Redemption. Shares of Series A Preferred Stock shall be redeemable, at
the option of the Corporation, in whole or part at any time or from time to time
after April 30, 1989 at the redemption prices set forth below (expressed as
percentages of the $20.00 stated value of each share of Series A Preferred
Stock), plus an amount equal to accrued and unpaid dividends (whether or not
declared) to the date fixed for redemption; provided that shares of Series A
Preferred Stock may also be redeemed by the Corporation prior to May 1, 1989 in
connection with the receipt of a Disapproval Notice (as defined in Paragraph (3)
below) as provided in the third paragraph of this Paragraph (2). After April 30,
1997, the Series A Preferred Stock may be redeemed at 100% of its stated value.

     If redeemed during the twelve-month period ending April 30,

</TABLE>

     In the event that the Corporation receives a Disapproval Notice, the
Corporation shall be entitled to give notice of redemption and to redeem all
shares of Series A Preferred Stock held by the holder giving or deemed to have
given such Disapproval Notice at 100% of the stated value of each share of
Series A Preferred Stock, plus an amount equal to accrued and unpaid dividends
(whether or not declared) to the date fixed for redemption. Notice of redemption
in response to a Disapproval Notice must be sent prior to the date of the
meeting to which such Disapproval Notice relates. The Corporation must deposit
the funds necessary to effect such redemption in response to a Disapproval
Notice in a bank or trust company pursuant to the terms of the seventh paragraph
of this Paragraph (2) contemporaneously with the giving of such notice of
redemption and all such funds shall be paid or available for payment at such
bank or trust company to




                                      -3-
<PAGE>   58
holders of the Series A Preferred Stock prior to the consummation of the 
transaction to which the Disapproval Notice relates.

     In case of the redemption of only part of the Series A Preferred Stock at 
the time outstanding (other than a redemption in response to a Disapproval 
Notice), such redemption shall be made pro rata; provided, however, that, 
except in the case of a redemption in response to a Disapproval Notice, if full 
cumulative dividends shall not have been paid or declared and set apart for 
payment for all quarterly dividends to and including the last dividend payment 
date, the Corporation shall not call for redemption any shares of Series A 
Preferred Stock unless all such shares then outstanding are called for 
simultaneous redemption.

     Notice of any proposed redemption of Series A Preferred Stock shall be 
given by the Corporation by mailing by first class mail a copy of such notice 
at least 10 days prior to the date fixed for such redemption to each holder of 
record of the shares to be redeemed at his address appearing on the books of 
the Corporation. Notice of redemption shall be deemed to have been given when
deposited in the United States mails, first class postage prepaid, whether or
not such notice is actually received. If on or before the redemption date
specified in such notice all funds necessary for such redemption shall have been
set aside by the Corporation, separate and apart from its other funds, in trust
for the pro rata benefit of the holders of the shares so called for redemption,
so as to be and continue to be available therefor, then from and after the date
of redemption so designated, notwithstanding that any certificate representing
shares of Series A Preferred Stock so called for redemption shall not have been
surrendered for cancellation, the shares represented thereby shall no longer be
deemed outstanding, the right to receive dividends thereon shall cease to accrue
and all rights with respect to such shares of Series A Preferred Stock so called
for redemption shall forthwith at the close of business on such redemption date
cease and terminate, except only the right of the holders thereof to receive the
redemption price of such shares so to be redeemed plus an amount equal to
accrued and unpaid dividends (whether or not declared) up to the date fixed for
redemption, but without interest thereon.

     Any moneys so set aside by the Corporation and unclaimed at the end of 
three years from the date fixed for


                                      -4-
<PAGE>   59
redemption shall revert to the general funds of the Corporation.

     The Corporation may, however, prior to the redemption date specified in 
the notice of redemption, deposit in trust for the account of the holders of the
shares of Series A Preferred Stock to be redeemed, with a bank or trust company
in good standing organized under the laws of the United States of America or of
any state thereof, having its principal office located in the continental United
States, and having a capital, surplus and undivided profits aggregating at least
$50 million, designated in such notice of redemption, all funds necessary for
such redemption (including accrued and unpaid dividends up to the date fixed for
redemption), together with irrevocable written instructions authorizing such
bank or trust company, on behalf and at the expense of the Corporation, to cause
the notice of redemption to be mailed as herein provided at least 10 days prior
to the redemption date and to include in said notice of redemption a statement
that all funds necessary for such redemption have been so deposited in trust and
are immediately available, and on the redemption date, notwithstanding that any
certificate representing shares of Series A Preferred Stock called for
redemption shall not have been surrendered for cancellation, all shares of
Series A Preferred Stock with respect to which such deposit shall have been made
and which are outstanding on such redemption date shall no longer be deemed to
be outstanding and all rights with respect to such shares of Series A Preferred
Stock shall forthwith at the close of business on such redemption date cease and
terminate, except only the right of the holders thereof to receive from such
bank or trust company, at any time after the redemption date, the redemption
price of such shares so to be redeemed plus accrued and unpaid dividends up to
the date fixed for redemption. In the event the holder of any such shares of
Series A Preferred Stock shall not, within three years after the redemption
date, claim the amount deposited for the redemption thereof, the depositary
shall, upon the request of the Corporation expressed in a resolution of its
Board of Directors, pay over to the Corporation such unclaimed amount.

     If any shares of Series A Preferred Stock called for redemption are not 
issued and outstanding as of the date fixed for redemption, the amount set 
aside or deposited for the redemption thereof shall revert to or be paid over 
to the Corporation.


                                      -5-
<PAGE>   60
     Any shares of Series A Preferred Stock which are redeemed or otherwise
purchased or acquired by the Corporation or any subsidiary thereof shall be
cancelled. The number of shares of Series A Preferred Stock shall be reduced by
the number of shares so cancelled and such cancelled shares shall be restored to
the status of authorized but unissued shares of Preferred Stock that are
undesignated as to series. For the purposes of this paragraph, a subsidiary
means a corporation of which a majority of the capital stock having voting power
under ordinary circumstances to elect a majority of the board of directors is
owned by (a) the Corporation, (b) the Corporation and one or more of its
subsidiaries or (c) one or more of the Corporation's subsidiaries.

     (3) Regarding Voting Rights. Each share of Series A Preferred Stock shall
entitle the holder thereof to one vote for each share held and, except as
provided herein, or by law, the Series A Preferred Stock and the Common Stock
(and any other capital stock of the Corporation at any time entitled to vote)
shall vote together as one class.

     In addition to any provisions herein and any requirement of law, the Series
A Preferred Stock shall vote as a single class with respect to any proposal (a)
to change the dividend rate, liquidation preference, redemption price, voting
rights or conversion rights of the shares of the Series A Preferred Stock or to
increase the number of authorized shares of Series A Preferred Stock; (b) to
increase the authorized amount of any class of capital stock of the Corporation
unless the same ranks junior to the Series A Preferred Stock as to dividends and
assets; (c) to authorize, create, issue or sell any shares of any class (or any
series of any class) of capital stock of the Corporation that ranks pari passu
with or prior to the Series A Preferred Stock as to dividends or distribution of
assets upon liquidation (collectively, the "Priority Stock"); (d) for the merger
or consolidation of the Corporation with or into, or the sale of substantially
all of the assets of the Corporation to, any other entity; and (e) for the
alteration, change or modification of the rights set forth in this paragraph.

     Unless the vote of a larger percentage is required by law or the Restated
Articles of Incorporation, the affirmative vote of the holders of a majority of
the outstanding shares of Series A Preferred Stock shall be sufficient to take
any action as to which a class vote of the holders of the Series A Preferred
Stock is required by law or the



                                      -6-
<PAGE>   61
Restated Articles of Incorporation. In the event that the holders of the Series
A Preferred Stock are entitled to vote as a class with respect to any matter
referred to in clause (d) of the preceding paragraph ("Clause (d) Matter"), the
Corporation shall give the holders of the Series A Preferred Stock at least 30
days' notice of any meeting at which a Clause (d) Matter shall be submitted to
shareholders, and each holder of Series A Preferred Stock shall be obligated to
notify the Corporation in writing (by execution of a proxy or otherwise), by
delivery of such notice to the Corporation, at least ten days prior to the date
of any such meeting whether such holder intends to vote in support of or in
opposition to the Clause (d) Matter. Simultaneously with the delivery of such
notice and if the holder indicates that it intends to vote in support of the
Clause (d) Matter, the holder shall deliver a legally binding and irrevocable
proxy authorizing the Corporation or officers thereof to so vote such holder's
shares of Series A Preferred Stock. Any holder who actually receives the
Corporation's notice of meeting with respect to a Clause (d) Matter and who
indicates that it intends to vote in opposition to the Clause (d) Matter or who
fails to deliver such notice together with such proxy within the required time
period shall be deemed to have given a "Disapproval Notice" to the Corporation.
If the Corporation elects to give notice of redemption and to redeem the Series
A Preferred Stock held by a holder giving a Disapproval Notice as provided in
the third paragraph of Paragraph (2) above, the holder of any such shares of
Series A Preferred Stock shall, effective upon the deposit by the Corporation of
the funds necessary to effect such redemption, be deemed to have granted an
irrevocable proxy to the Corporation to vote all such shares of Series A
Preferred Stock registered in the name of such holder in support of the Clause
(d) Matter and to vote on all other matters in the manner determined by the
Board of Directors of the Corporation at the meeting.

     Whenever, at any time, dividends payable on the Series A Preferred Stock
shall be in arrears for such number of dividend periods as shall in the
aggregate contain not less than 540 calendar days, the holders of the Series A
Preferred Stock shall have the exclusive right, voting separately as a class to
elect by a majority of the votes cast two directors of the Corporation, who
shall be a Class I director and a Class II director, respectively, (i) at the
Corporation's next annual meeting of shareholders, (ii) at a special meeting 
held in place thereof, (iii) at a special



                                      -7-
<PAGE>   62
meeting of the holders of shares of the Series A Preferred Stock called by the
Secretary of the Corporation upon the written request of the holders of record
of 25% or more of the total number of shares of Series A Preferred Stock then
outstanding, to be held within 30 days after delivery of such request, or (iv)
by written consent of the holders of a majority of the issued and outstanding
shares of Series A Stock in lieu thereof, and at each succeeding meeting of
shareholders thereafter at which directors shall be elected until such rights
shall terminate as hereinafter provided. The Board of Directors of the
Corporation hereby unanimously directs the Secretary of the Corporation to give
notice of any special meeting of the shareholders of the Corporation required
from time to time by the provisions of this Paragraph (3), in the manner
prescribed by the Bylaws of the Corporation. At elections for such directors,
each holder of the Series A Preferred Stock shall be entitled to one vote for
each share held. Upon the vesting of such voting right in the holders of the
Series A Preferred Stock, the maximum authorized number of members of the Board
of Directors shall automatically be increased by two and the two vacancies so
created shall be filled by vote of the holders of the Series A Preferred Stock
as hereinabove set forth. The right of the holders of the Series A Preferred
Stock, voting separately as a class, to elect members of the Board of Directors
of the Corporation as aforesaid shall continue until such time as all dividends
accumulated on the Series A Preferred Stock shall have been paid in full, at
which time such right shall terminate, except as by law expressly provided,
subject to revesting in the event of each and every subsequent default of the
character above mentioned. Upon any termination of the right of the holders of
the Series A Preferred Stock to vote for directors as herein provided, the term
of office of all directors then in office elected by such series voting as a
class shall terminate immediately. If the office of any director elected by the
holders of the Series A Preferred Stock becomes vacant by reason of death,
resignation, retirement, disqualification, removal from office, or otherwise,
the remaining director elected by the holders of Series A Preferred Stock voting
as a class may choose a successor who shall hold office for the unexpired term
in respect of which such vacancy occurred.  Whenever the special voting powers
vested in the holders of the Series A Preferred Stock shall have expired, the
number of directors shall become such number as may be provided for in the
By-Laws, or resolution of the Board of Directors



                                      -8-
<PAGE>   63
thereunder, irrespective of any increase made pursuant to the provisions of this
Paragraph (3).

     (4) Priority in Event of Dissolution. In the event of any liquidation,
dissolution, or winding up of the affairs of the Corporation, after payment or
provision for payment of the debts and other liabilities of the Corporation
(including any liquidation preferences payable in respect of capital stock of
the Corporation ranking senior to the Series A Preferred Stock as to assets),
the holders of the Series A Preferred Stock shall be entitled to receive, out of
the remaining net assets of the Corporation, $20.00 in cash for each share of
Series A Preferred Stock, plus an amount equal to all dividends accrued and
unpaid on each such share (whether or not declared) up to the date fixed for
distribution, before any distribution shall be made to the holders of the Common
Stock of the Corporation or any other stock of the Corporation ranking junior to
the Series A Preferred Stock as to assets.  If upon any liquidation, dissolution
or winding up of the affairs of the Corporation, the assets distributable among
the holders of Series A Preferred Stock (and any other capital stock of the
Corporation ranking on a parity with the Series A Preferred Stock as to assets)
shall be insufficient to permit the payment in full to the holders of all shares
of such Series A Preferred Stock (and any other capital stock of the Corporation
ranking on a parity with the Series A Preferred Stock as to assets) of all
preferential amounts payable to all such holders, then the entire assets of the
Corporation thus distributable shall be distributed ratably among the holders of
the Series A Preferred Stock (and any other capital stock of the Corporation
ranking on a parity with the Series A Preferred Stock as to assets) in
proportion to the respective amounts that would be payable per share if such
assets were sufficient to permit payment in full.

     (5) Conversion. (a) Subject to and upon compliance with the provisions
herein, at the option of the holder, shares of Series A Preferred Stock may, at
any time on and after September 1, 1987, be converted into fully paid and
nonassessable shares of Common Stock at the rate of .500 of a share of Common
Stock for each share of Series A Preferred Stock to be converted (subject to the
adjustment as hereinafter provided) ("conversion rate"); provided, however, that
if the Corporation shall have given notice of redemption of any shares of Series
A Preferred Stock pursuant to Paragraph (2) above, the right to convert such
shares shall terminate at 5:00 p.m., Houston, Texas time, on the date fixed for
redemption (unless the Corporation shall default



                                      -9-
<PAGE>   64
in the payment due upon redemption in which case such conversion rights shall
not expire). the result obtained by dividing $10.00 by the conversion rate in
effect from time to time is herein referred to as the "conversion price."
Whenever the conversion price is adjusted pursuant to the provisions of
Subparagraph (d) below, the conversion rate shall be redetermined by dividing
$10.00 by the then adjusted conversion price. The conversion rate and the
conversion price in effect from time to time shall be calculated to four decimal
places and rounded to the nearer thousandths.

     (b) In order to exercise the right to convert, the holder of any shares of
Series A Preferred Stock to be converted shall surrender the certificate
representing such Series A Preferred Stock, accompanied (if so required by the
Corporation) by the proper instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder thereof
or by his attorney duly authorized in writing, to the Corporation at its
principal executive office, and shall give written notice to the Corporation at
such office that the holder elects to convert such Series A Preferred Stock.  No
payment or adjustment shall be made upon any conversion on account of regular
cash dividends declared or accrued on the Common Stock or the Series A Preferred
Stock surrendered for conversion.  Series A Preferred Stock shall be deemed to
have been converted immediately prior to the close of business on the date of
the giving of such notice and of the surrender of such certificates for
conversion in accordance with the foregoing provisions, and at such time the
rights of the holder of such Series A Preferred Stock as such holder shall
cease, and the holder thereof shall be treated for all purposes as the record
holder of Common Stock from and after such time. As promptly as practicable
after receipt of such notice and the surrender of such certificates as
aforesaid, the Corporation shall issue and deliver at such office a certificate
or certificates for the number of full shares of Common Stock issuable upon
conversion.

     (c) No fractional share of Common Stock shall be issued upon conversion of
Series A Preferred Stock. Instead of any fractional share of Common Stock which
would otherwise be issuable upon conversion of any Series A Preferred Stock, the
Corporation shall pay a cash adjustment equal to such fraction multiplied by the
Price per share of the Common Stock on the trading day next preceding the date
of conversion. In determining the number of shares of Common



                                      -10-
<PAGE>   65
Stock and the payment, if any, in lieu of fractional shares that a holder of 
Series A Preferred Stock shall receive, the total number of shares of Series A 
Preferred Stock surrendered for conversion by such holder shall be aggregated.

     (d)  The number and kind of securities issuable upon the conversion of the 
Series A Preferred Stock shall be subject to adjustment from time to time upon 
the happening of certain events occurring on or after the date of original 
issue of the shares of the Series A Preferred Stock as follows:

          (i)  In case of any reclassification or change of outstanding 
     securities issuable upon exercise of the conversion rights (other than a
     change in par value, or from par value to no par value, or from no par
     value to par value or as a result of a subdivision or combination), or in
     the case of any consolidation or merger of the Corporation with or into
     another corporation (other than a merger with another corporation in which
     the Corporation is the surviving Corporation and which does not result in
     any reclassification or change -- other than a change in par value, or from
     par value to no par value, or from no par value to par value, or as a
     result of a subdivision or combination -- of outstanding securities
     issuable upon exercise of these conversion rights), the holders of the
     Series A Preferred Stock shall have, and the Corporation, or such successor
     corporation, shall covenant in the constituent documents effecting any of
     the foregoing transactions that the holders of the Series A Preferred Stock
     do have, the right to obtain upon the exercise of these conversion rights,
     in lieu of each share of Common Stock theretofore issuable upon exercise of
     these conversion rights, the kind and amount of shares of stock, other
     securities, money and property receivable upon such reclassification,
     change, consolidation or merger by a holder of one share of Common Stock
     issuable upon exercise of these conversion rights as if they had been
     exercised immediately prior to such reclassification, change, consolidation
     or merger. The constituent documents effecting any reclassification,
     change, consolidation or merger shall provide for any adjustments which
     shall be as nearly equivalent as may be practicable to the adjustments
     provided in this Subparagraph (d). The provisions of this Subparagraph


                                      -11-
<PAGE>   66
     (d)(i) shall similarly apply to successive reclassifications, changes, 
     consolidations or mergers.

          (ii)      If the Corporation at any time while any of the Series A 
     Preferred Stock is outstanding, shall subdivide or combine its Common
     Stock, the conversion price shall be proportionately reduced, in case of
     subdivision of shares, as at the effective date of such subdivision, or if
     the Corporation shall take a record of holders of its Common Stock for the
     purpose of so subdividing, as at such record date, whichever is earlier, or
     shall be proportionately increased, in the case of combination of shares,
     as at the effective date of such combination or, if the Corporation shall
     take a record of holders of its Common Stock for the purpose of so
     combining, as at such record date, whichever is earlier.

          (iii)      If the Corporation at any time while any of the Series A 
     Preferred Stock is outstanding shall:

                    (A)  Pay a dividend payable in, or make any other 
          distribution of, Common Stock, the conversion price shall be adjusted,
          as at the date the Corporation shall take a record of the holders of
          its Common Stock for the purpose of receiving such dividend or other
          distribution (or if no such record is taken, as at the date of such
          payment or other distribution), to that price determined by
          multiplying the conversion price in effect immediately prior to such
          record date (or if no such record is taken, then immediately prior to
          such payment or other distribution) by a fraction (1) the numerator of
          which shall be the total number of shares of Common Stock outstanding
          immediately prior to such dividend or distribution, and (2) the
          denominator of which shall be the total number of shares of Common
          Stock outstanding immediately after such dividend or distribution
          (plus in the event that the Corporation paid cash for fractional
          shares, the number of additional shares which would have been
          outstanding had the Corporation issued fractional shares in connection
          with said dividend, except to the extent such payment of cash is
          treated as a dividend payable out of earnings or surplus legally
          available for the payment of dividends under the laws of the State of
          Louisiana); or


                                      -12-
<PAGE>   67
          (B)  Make a distribution of its assets to the holders of its Common
     Stock as a dividend in liquidation or partial liquidation or by way of
     return of capital or other than as a dividend payable out of earnings or
     surplus legally available for dividends under the laws of the State of
     Louisiana, the holders of the Series A Preferred Stock shall, upon exercise
     of these conversion rights, be entitled to receive, in addition to the
     number of shares of Common Stock receivable thereupon, and without payment
     of any consideration therefor, a sum equal to the amount of such assets as
     would have been deliverable to them as owners of that number of shares of
     Common Stock of the Corporation receivable by exercise of these conversion
     rights, had they been the holders of record of such Common Stock on the
     record date for such distribution (or if no such record is taken, as of the
     date of such distribution); and an appropriate provision therefore shall be
     made a part of any such distribution.

     (iv) If the Corporation at any time while any of the Series A Preferred 
Stock is outstanding shall issue any additional shares of Common Stock 
(otherwise than as provided in the foregoing Subparagraphs (i) through (iii) 
above) at a price per share less than the average Price per share of Common 
Stock for the 20 trading days immediately preceding the date of the 
authorization of such issuance by the Corporation's Board of Directors (the 
"Market Price") then the conversion price on each such issuance shall be 
adjusted to that price determined by multiplying the conversion price by a 
fraction:

          (A)  the numerator of which shall be the sum of (1) the number of
     shares of Common Stock outstanding immediately prior to the issuance of
     such additional shares of Common Stock multiplied by the Market Price, and
     (2) the consideration, if any, received and deemed received by the
     Corporation upon the issuance of such additional shares of Common Stock,
     divided by (3) the total number of shares of Common Stock outstanding
     immediately after the issuance of such additional shares of Common Stock,
     and

          (B)  the denominator of which shall be the Market Price.


                                      -13-




<PAGE>   68
     No adjustment of the conversion price shall be made in an amount less than 
$.05 per share, but any such lesser adjustment shall be carried forward and 
shall be made at the time together with the next subsequent adjustment which, 
together with any adjustments so carried forward, shall amount to $.05 per 
share or more. Further, no adjustments of the conversion price shall be made 
under this Subparagraph (d)(iv) upon the issuance of any additional shares of 
Common Stock that (x) are issued pursuant to thrift plans, stock purchase 
plans, stock bonus plans, stock option plans, employee stock ownership plans 
and other incentive or profit sharing arrangements for the benefit of 
employees, provided such plans or arrangements have been approved by a majority 
of either the disinterested members of the Board of Directors of the 
Corporation or the Corporation's stockholders ("Employee Benefit Plans") or (y) 
are issued pursuant to any Common Stock Equivalent (as defined in 
Subparagraph (d)(v) below), if upon the issuance of any such Common Stock 
Equivalent, any such adjustments shall previously have been made pursuant to 
Subparagraph (d)(v) hereof or if no adjustment was required pursuant to 
Subparagraph (d)(v) hereof.

     The Price per share of Common Stock on any day means the average (mean) of 
the reported "high" and "low" sales prices for such shares as reported in The 
Wall Street Journal's NYSE-Composite Transactions listing for such day 
(corrected for obvious typographical errors), or if such shares are not 
reported in such listing, then the average of the reported "high" and "low" 
sales prices on the largest national securities exchange (based on the 
aggregate dollar value of securities listed) on which such shares are listed or 
traded, or if such shares are not listed or traded on any national securities 
exchange, then the average of the reported "high" and "low" sales prices for 
such shares in the over-the-counter market, as reported on the National 
Association of Securities Dealers Automated Quotations System, or, if such 
prices shall not be reported thereon, the average between the closing bid and 
asked prices so reported, or, if such prices shall not be reported, then the 
average closing bid and asked prices reported by the National Quotation Bureau 
Incorporated, or, in all other cases, the value established by the Board of 
Directors of the Corporation in good faith. The "average" Price per share of 
the Common Stock for any period shall be determined by


                                      -14-
<PAGE>   69
dividing the sum of the Prices determined for the individual days in such period
by the number of days in such period.

     (v) In case the Corporation shall issue any security or evidence of 
indebtedness which is convertible into or exchangeable for Common Stock
("Convertible Security"), or any warrant, option or other right to subscribe for
or purchase Common Stock or any Convertible Security, other than pursuant to
Employee Benefit Plans, ("Common Stock Equivalent"), or if, after any such
issuance, the price per share for which additional shares of Common Stock may be
issuable thereunder is amended, then the conversion price upon each such
issuance or amendment shall be adjusted as provided in Subparagraph (d)(iv)
hereof on the basis that (i) the maximum number of additional shares of Common
Stock issuable pursuant to all such Common Stock Equivalents shall be deemed to
have been issued as of the earlier of (a) the date on which the Corporation
shall enter into a firm contract for the issuance of such Common Stock
Equivalent, or (b) the date of actual issuance of such Common Stock Equivalent;
and (ii) the aggregate consideration for such maximum number of additional
shares of Common Stock shall be deemed to be the minimum consideration received
and receivable by the Corporation for the issuance of such additional shares of
Common Stock pursuant to such Common Stock Equivalent; provided, however, that
no adjustment shall be made pursuant to this Subparagraph (d)(v) unless the
consideration received and receivable by the Corporation per share of Common
Stock for the issuance of such additional shares of Common Stock pursuant to
such Common Stock Equivalent is less than the Market Price.  No adjustment of
the conversion price shall be made under this Subparagraph upon the issuance of
any Convertible Security which is issued pursuant to the exercise of any
warrants or other subscription or purchase rights therefor, if any adjustment
shall previously have been made in the conversion price than in effect upon the
issuance of such warrants or other rights pursuant to this Subparagraph (d)(v).

     (vi) The following provisions shall be applicable to making of adjustments 
in the conversion price hereinbefore provided in this Subparagraph (d): 


                                      -15-
<PAGE>   70
     (A)  The consideration received by the Corporation shall be deemed to be
the following: to the extent that any additional shares of Common Stock or any
Common stock Equivalents shall be issued for cash consideration, the
consideration received by the Corporation therefor, or, if such additional
shares of Common Stock or Common Stock Equivalents are offered by the
Corporation for subscription, the subscription price, or, if such additional
shares of Common stock or Common Stock Equivalents are sold to underwriters or
dealers for public offering without a subscription offering, the initial public
offering price, in any such case excluding any amounts paid or receivable for
accrued interest or accrued dividends and without deduction of any compensation,
discounts or expenses paid or incurred by the Corporation for and in the
underwriting of, or otherwise in connection with, the issue thereof; to the
extent that such issuance shall be for a consideration other than cash, then,
except as herein otherwise expressly provided, the fair market value of such
consideration at the time of such issuance as determined in good faith by the
Corporation's Board of Directors. The consideration for any additional shares of
Common Stock issuable pursuant to any Common stock Equivalents shall be the
consideration received by the Corporation for issuing such Common Stock
Equivalents, plus the additional consideration payable to the corporation upon
the exercise, conversion or exchange of such Common Stock Equivalents. In case
of the issuance at any time of any additional shares of Common Stock or Common
Stock Equivalents in payment or satisfaction of any dividend upon any class of
stock other than Common Stock, the Corporation shall be deemed to have received
for such additional shares of Common Stock or Common stock Equivalents a
consideration equal to the amount of such dividend so paid or satisfied. In any
case in which the consideration to be received or paid shall be other than cash,
the Board of Directors of the Corporation shall notify promptly each holder of
the Series A Preferred Stock of its determination of the fair market value of
such consideration.




                                      -16-
<PAGE>   71
               (B)  Upon the expiration of the right to convert, exchange or
          exercise any Common Stock Equivalent the issuance of which effected an
          adjustment in the conversion price, if any such Common Stock
          Equivalent shall not have been converted, exercised or exchanged, the
          number of shares of Common Stock deemed to be issued and outstanding
          by reason of the fact that they were issuable upon conversion,
          exchange or exercise of any such Common Stock Equivalent shall no
          longer be computed as set forth above, and the conversion price shall
          forthwith be readjusted and thereafter be the price which it would
          have been (but reflecting any other adjustments in the conversion
          price made pursuant to the provisions of Subparagraph (d)(iv) after
          the issuance of such Common Stock Equivalent) had the adjustment of
          the conversion price made upon the issuance or sale of such Common
          Stock Equivalent been made on the basis of the issuance only of the
          number of additional shares of Common Stock actually issued upon
          exercise, conversion or exchange of such Common Stock Equivalents and
          thereupon only the number of additional shares of Common Stock
          actually so issued shall be deemed to have been issued and only the
          consideration actually received by the Corporation (computed as in
          Subparagraph (A) of this Subparagraph (d)(vi)) shall be deemed to have
          been received by the Corporation.

               (C)  The number of shares of Common Stock at any time outstanding
          shall not include any shares thereof then directly or indirectly owned
          or held by or for the account of the Corporation or its subsidiaries.

     (e)  Whenever the conversion price and the conversion rate are required to
be adjusted as provided herein, the Corporation shall forthwith compute the
adjusted conversion price and the adjusted conversion rate and shall prepare a
certificate setting forth such adjusted conversion price and adjusted conversion
rate and showing in detail the facts upon which such adjustment is based. A copy
of such certificate shall forthwith be filed with the transfer agent or agents
for the Series A Preferred Stock (if any) and for the Common Stock; and
thereafter, until further adjusted, the




                                      -17-
<PAGE>   72
adjusted conversion price and the adjusted conversion rate shall be as set forth
in such certificate, provided that the computation of such adjusted conversion
price and such adjusted conversion rate shall be reviewed at least annually by
the independent public accountants regularly employed by the Corporation and
said accountants shall file a corrected certificate, if required, with such
transfer agent or agents. The Corporation shall mail or cause to be mailed to
the holders of Series A Preferred Stock at the time of each quarterly dividend
payment, a statement setting forth the adjustments, if any, made in the
applicable conversion price and conversion rate and not theretofore reported to
such holders, and the reasons for such adjustment.

     (f) The Corporation will at all times reserve and keep available, out of 
its authorized and unissued Common Stock solely for the purpose of issuance 
upon the conversion of the Series A Preferred Stock as herein provided, free 
from preemptive and other subscription rights, such number of shares of Common 
Stock as shall then be issuable upon the conversion of all outstanding Series 
A Preferred Stock. The Corporation shall ensure that all shares of Common Stock 
which shall be so issuable shall upon issue be duly and validly issued and 
fully paid and nonassessable.

     (g) If any shares of Common Stock required to be reserved for the purposes 
of conversion of Series A Preferred Stock hereunder require registration with 
or approval of any governmental authority under any federal or state law, or 
listing upon any national securities exchange, before such shares may be issued 
upon conversion, the Corporation will in good faith and as expeditiously as 
possible endeavor to cause such shares to be duly registered, approved or 
listed, as the case may be.

     (h) The issuance of certificates for shares of Common Stock upon the 
conversion of Series A Preferred Stock shall be made without charge to the 
holders thereof for any transfer or similar taxes that may be payable in 
respect of the issue, delivery or acquisition of such certificates. Such 
certificates shall be issued in the respective names of the holders of the 
Series A Preference Stock converted.

     (6) Sinking Fund. The Series A Preferred Stock shall not be entitled to any
mandatory redemption or prepayment (except on liquidation, dissolution or 
winding up of the


                                      -18-
<PAGE>   73
affairs of the Corporation) or to the benefit of any sinking fund.

     (7) Definition. If the day upon which any payment is to be made or any 
other action is to be taken or any event is scheduled to occur pursuant to the 
terms of Articles of Amendment is not a business day, the payment shall be made 
or the other action shall be taken on the next succeeding business day. A 
"business day" is defined as a day in the City of Houston, County of Harris, 
Texas, that is not a legal holiday or a day on which banking institutions are 
authorized or obligated by law to close.

     (8) Notice. Any notice, demand or other communication shall be deemed 
given and received as of the date of delivery in person or receipt set forth on 
the return receipt. The inability to deliver because of rejection or other 
refusal to accept any notice, demand or other communication, shall be deemed to 
be receipt of such notice, demand or other communication as of the date of such 
inability to deliver or rejection or refusal to accept.

     2. Paragraph C of Article III is relettered as paragraph D.

     APPEARERS further stated that all of the shares of the Corporation have 
par value; that the Corporation is authorized to issue 25,000,000 shares, of
which 20,000,000 are common shares of the par value of $2.50 per share and
5,000,000 are preferred shares of the par value of $0.10 per share; and that the
Board of Directors of the Corporation has the authority to amend the articles to
fix the preferences, limitations, and relative rights of the preferred shares,
and to establish, and fix variations and relative rights and preferences as
between series of preferred shares, all as more fully set out in Article III of
the Restated Articles of Incorporation.

     AND SAID APPEARERS having requested me, Notary, to note said amendment in 
authentic form, I do by these presents receive said amendments in the form of
this public act to the end that said amendment may be promulgated and recorded
and thus be read into the Restated Articles of Incorporation of Southdown, Inc.,
as hereinabove set forth.

                                SOUTHDOWN, INC.

     Southdown, Inc., a Louisiana corporation (the "corporation"), through its
undersigned President and Secretary and by authority of its Board of Directors,
does hereby certify that:

     FIRST: The Restated Articles of Incorporation set forth in Paragraph Fourth
below accurately copies the articles and all amendments and corrections thereto

     SECOND: Each amendment and correction has been effected in conformity with
law.

     THIRD: The date of incorporation of the corporation was April 4, 1930, and
the date of these Restated Articles is September 15, 1983.

     FOURTH: The Restated Articles of Incorporation of the corporation are as
follows:

                                   ARTICLE I

     The name of this corporation shall be Southdown, Inc.

                                   ARTICLE II

     The corporation's purpose is to engage in any lawful activity for which
corporations may be formed under the Business Corporation Law of Louisiana.

                                  ARTICLE III

     A.   The Corporation has authority to issue 20,000,000 shares of Common
Stock of the par value of $2.50 per share (the "Common Stock") and 5,000,000
shares of Preferred Stock of the par value of $.10 per share (the "Preferred
Stock").

     B.   Shares of the Preferred Stock may be issued from time to time in one
or more classes or series, each of which shall have such distinctive designation
or title and such voting rights, preferences and relative, optional or other
special rights (including, without limitation, pre-emptive rights) and
qualifications, limitations or restrictions as shall be fixed by the board of
directors of the corporation prior to the issuance of any shares thereof by
amendment to these Articles of Incorporation adopted by the board of directors.

     C.   Except to the extent otherwise provided by an amendment adopted by the
board of directors in accordance with the provisions of Article III(B) hereof,
no shareholder of this corporation shall by reason of his holding shares of any
class have any
<PAGE>   78
pre-emptive or preferential right to purchase or subscribe to any shares of any
class of this corporation now or hereafter authorized or any notes, debentures,
bonds, or other securities convertible into or carrying options or warrants to
purchase shares of any class now or hereafter to be authorized, whether or not
the issuance of any shares, or such notes, debentures, bonds or other securities
would adversely affect dividend or voting rights of such shareholder, other than
such rights, if any, as the board of directors in its discretion may fix; and
the board of directors may issue shares of any class of this corporation, or any
notes, debentures, bonds or other securities convertible into or carrying
options or warrants to purchase shares of any class, without offering any such
shares of any class, either in whole or in part, to the existing shareholders of
any class.

                                   ARTICLE IV

     All of the corporate powers of this corporation shall be vested in and
exercised by a board of directors consisting of the number of directors
specified in the by-laws of the corporation or determined in the manner
prescribed herein.

     The Board of Directors shall be divided into three classes as nearly equal
in number as may be, with the initial term of office of Class I expiring at the
annual meeting of shareholders in 1971, of Class II expiring at the annual
meeting of shareholders in 1972, and of Class III expiring at the annual meeting
of shareholders in 1973.

     At each annual meeting of shareholders, directors chosen to succeed those
whose terms then expire shall be elected for a full term of office expiring at
the third succeeding annual meeting of shareholders after their election. When
the number of directors is increased by amendment to the by-laws of the
corporation, and any newly created directorships are filled by the Board of
Directors, there shall be no classification of such additional directors until
the next annual meeting of shareholders. Subject to the foregoing, directors
elected to fill a vacancy shall hold office for a term expiring at the annual
meeting at which the term of the class to which they shall have been elected
expires.

     The shareholders, by the affirmative vote or consent of the holders of 80%
of all classes of stock of this corporation entitled to vote in elections of
directors, at any special meeting called for the purpose may remove from office
any one or more of the directors, notwithstanding that his or their terms of
office may not have expired, and may forthwith at such meeting proceed to elect
a successor for the unexpired term.

                                   ARTICLE V

     Any director absent from the meeting of the board of directors or any
committee thereof may be represented by any other director or shareholder, who
may cast the absent director's vote according to his written instructions,
general or special.

                                      -2-
<PAGE>   79
                                   ARTICLE VI

     The board of directors may make and alter by-laws containing any provisions
with respect to the government of the corporation, subject to the power of the
shareholders to change or repeal any by-laws so made. The by-laws may contain
any provision relating to the business of the corporation, the conduct of its
affairs, its rights or powers, or the rights or powers of its shareholders,
directors or officers, not inconsistent with law or these articles.

                                  ARTICLE VII

     No shareholder shall ever be held liable for the contracts, faults or debts
of the corporation in any further sum than the unpaid balance, if any, remaining
due on the stock for which he has subscribed, nor shall any informality in
organization have the effect of rendering any subscriber or shareholder liable
beyond the said unpaid amount, if any, remaining due on his stock.
 
                                  ARTICLE VIII

     Notwithstanding any other provision of this certificate of incorporation or
the by-laws of this corporation (and in addition to any other vote that may be
required by law, the Articles of Incorporation or the by-laws of this
corporation), the affirmative vote of the holders of 80% of all classes of stock
of this Corporation entitled to vote in elections of directors (considered for
this purpose as one class) shall be required to amend, alter, change, or repeal
Articles IV, VIII, VI, IX, X or XI of the Articles of Incorporation.

     Except as provided in the Articles of Incorporation, or as required by
statute, the Articles of Incorporation may be amended by the affirmative vote or
consent of the holders of a majority of all classes of stock of this corporation
entitled to vote in elections of directors, taken at an annual or special
meeting of shareholders, the notice of which set forth the proposed amendment or
a summary of the changes to be made thereby. If such an amendment would
adversely affect the holders of shares of any class or series, then in addition
to the vote required by the sentence immediately preceding, the holders of each
class or series of shares so affected by the amendment shall be entitled to vote
as a class upon such amendment, and a majority of the issued and outstanding
shares of each class or series so affected by the amendment shall be necessary
to the adoption thereof.

                                   ARTICLE IX

     (A)  Except as set forth in Paragraph (D) of this Article IX, the
affirmative vote or consent of the holders of 80% of all classes of stock of
this corporation entitled to vote in elections of directors, considered for the
purposes of this Article IX as one class, shall be required:


                                      -3-
<PAGE>   80
          (i) for a merger or consolidation with or into any other corporation, 
     or

         (ii) for any sale or lease of all or any substantial part of the assets
     of this corporation to any other corporation, person or other entity, or

        (iii) any sale or lease to this corporation or any subsidiary thereof 
     of any assets (except assets having an aggregate fair market value of less 
     than $2,000,000) in exchange for voting securities (or securities 
     convertible into voting securities or options, warrants, or rights to 
     purchase voting securities or securities convertible into voting 
     securities) of this corporation or any subsidiary by any other corporation,
     person or entity,

if as of the record date for the determination of shareholders entitled to
notice thereof and to vote thereon or consent thereto such other corporation,
person or entity which is party to such a transaction is the beneficial owner,
directly or indirectly, of 5% or more of the outstanding shares of stock of this
corporation entitled to vote in elections of directors, considered for the
purpose of the Article IX as one class. Such affirmative vote or consent shall
be in addition to the vote or consent of the holders of the stock of this
corporation otherwise required by law or any agreement between this corporation
and any national securities exchange.

     (B)  For purposes of this Article IX any corporation, person or other 
entity shall be deemed to be the beneficial owner of any share of stock of this
corporation,

          (i) which it owns directly, whether or not of record, or

         (ii) which it has the right to acquire pursuant to any agreement or 
     understanding or upon exercise of conversion rights, warrants or options or
     otherwise, or

        (iii) which are beneficially owned, directly or indirectly (including 
     shares deemed to be owned through application of clause (ii) above), by any
     "affiliate" or "associate" as those terms are defined in Rule 12b-2 of the 
     General Rules and Regulations under the Securities Exchange Act of 1934 as
     in effect on July 1, 1970, or

         (iv) which are beneficially owned, directly or indirectly (including 
     shares deemed owned through application of clause (ii) above), by any other
     corporation, person or entity with which it or its "affiliate" or 
     "associate" has any agreement or arrangement or understanding for the 
     purpose of acquiring, holding, voting or disposing of stock of this 
     corporation.


                                      -4-
<PAGE>   81
     For the purposes of this Article IX, the outstanding shares of any class of
stock of this corporation shall include shares deemed owned through the
application of clauses (B)(ii), (iii) and (iv) above, but shall not include any
other shares which may be issuable pursuant to any agreement or upon exercise of
conversion rights, warrants, options or otherwise.

     (C) The Board of Directors shall have the power and duty to determine for
the purposes of this Article IX on the basis of information known to this
corporation, whether

          (i) such other corporation, person or other entity beneficially owns

     below is substantially consistent with the transaction covered thereby.

     Any such determination shall be conclusive and binding for all purposes of
this Article IX.

     (D) The provisions of this Article IX shall not apply to,

          (i) any merger or similar transaction with any corporation if the
     Board of Directors of this corporation has approved a memorandum of

     prior to the time that such other corporation shall have become a

entitled thereto within one year after the dividend or redemption price became
payable or the shares became issuable, despite reasonable efforts by the
corporation to pay the dividend or redemption price or deliver the certificates
for the shares to such shareholders within such time, shall, at the expiration
of such time, revert to full ownership to the corporation, and the corporation's
obligation to pay such dividend or redemption price or issue such shares, as the
case may be, shall thereupon cease; provided that the board of directors may, at
any time, for any reason satisfactory to it, but need not, authorize (a) payment
of the amount of any cash or property dividend or redemption price, or (b)
issuance of any shares, ownership of which has reverted to the corporation

                             1989 STOCK OPTION PLAN

                                       OF

                                SOUTHDOWN, INC.



1.  PURPOSE OF PLAN

    This 1989 Stock Option Plan (the "Plan") is intended as an employment
incentive (a) to retain in the employ of Southdown, Inc. (the "Company") and
its Affiliates (as defined below) persons of training, experience and ability,
(b) to attract new employees whose services are considered unusually valuable,
(c) to encourage the sense of proprietorship of such persons, and (d) to
stimulate the active interest of such persons in the development and financial
success of the Company. It is further intended that certain options issued
pursuant to this Plan may constitute incentive stock options within the meaning
of Section 422A of the Internal Revenue Code of 1986, as amended ("Code"),
while certain other options granted under this Plan will be nonqualified
options within the meaning of Section 83 of the Code. As used in this Plan, the
term "Affiliates" means any Parent of the Company and any Subsidiary of the
Company within the meaning of Sections 425(e) and (f) of the Code,
respectively.

2.  ADMINISTRATION OF PLAN

    (a) The Board of Directors shall appoint and maintain as administrator of
this Plan the Employee Compensation and Benefits Committee (the "Committee")
which shall consist of at least three members of the Board of Directors. No
member of the Committee shall have been eligible to participate in this Plan or
any other plan of the Company or its Affiliates which entitles participants to
acquire stock appreciation rights or stock options of the Company or its
Affiliates at any time within one year prior to appointment. No member of such
Committee shall be eligible to receive stock options under this Plan
("Options") or any other plan of the Company or its Affiliates while serving on
the Committee. The limitations set forth in the preceding two sentences shall
not be applicable to participation in any nonemployee director stock option
plan maintained by Company in which the participation of nonemployee directors
is not subject to any nonemployee director discretion and would not adversely
affect any such nonemployee director's status as a disinterested member of the
Committee within the meaning of Rule 16b-3 promulgated by the Securities and
Exchange Commission ("Commission") pursuant to the Securities Exchange Act of
1934, as amended ("Exchange Act"). The members of the Committee shall serve at
the pleasure of the Board of Directors. The Committee shall have full power and
authority to designate participants, to determine the terms and provisions of
respective option agreements (which need not be identical) and to interpret the
provisions and supervise the administration of this Plan. All decisions and
selections made by the Committee pursuant to the provisions of this Plan shall
be made by a majority of its members. Any decision reduced to writing and
signed by all of the members shall be fully effective as if it had been made by
a majority at a meeting duly held.

    (b) All Options granted under this Plan are subject to, and may not be
exercised before, the approval of this Plan at the 1990 Annual Meeting, or at a
special meeting of shareholders called for that purpose prior to the 1990
Annual Meeting of Shareholders, by the affirmative vote of the holders of a
majority of the outstanding shares of the Company present, or represented by
proxy, and entitled to vote thereat; provided that if such approval by the
shareholders of the Company at the annual or special meeting is not
forthcoming, all Options previously granted under this Plan shall be void.

    (c) The Committee shall have the authority to designate which Options
granted under this Plan shall be incentive stock options and which shall be
nonqualified stock options. The Committee, in its sole discretion, may
determine that all the Options granted under this Plan may be incentive or
nonqualified options.


                                     - 1 -
<PAGE>   2

    (d) The Committee shall have the authority to set the number of shares of
the option granted to any one grantee with the limitation that the total number
of shares that may effectively be granted under stock options to any one
grantee in any one calendar year may not exceed 200,000 shares. Such number of
shares is subject to adjustment as provided in Paragraph 9 of this Plan.

3.  DESIGNATION OF PARTICIPANTS

    The persons eligible for participation in this Plan as recipients of
Options shall include only key employees of the Company and its Affiliates.
Directors of the Company shall not be eligible to participate in this Plan as
directors, but directors otherwise qualified shall be eligible to participate.
An employee who has been granted an Option hereunder ("Optionee") may be
granted an additional Option or Options, if the Committee shall so determine.

4.  STOCK RESERVED

    Subject to adjustment as provided in Paragraph 9, a total of 5,000,000
shares ("Stock") of Common Stock, par value $1.25 per share, of the Company
("Common Stock") shall be subject to this Plan. The shares of Stock subject to
this Plan shall consist of unissued shares or previously issued shares
reacquired and held by the Company or its Affiliates, and such number of shares
shall be and is hereby reserved for sale for such purpose. Any of such shares
which may remain unsold and which are not subject to outstanding Options at the
expiration of this Plan shall cease to be reserved for the purpose of this
Plan, but until termination of this Plan and the expiration, exercise or lapse
of all Options granted hereunder, the Company shall at all times reserve a
sufficient number of shares to meet the requirements of this Plan. Should any
Option expire or be cancelled prior to its exercise or relinquishment in full,
the shares theretofore subject to such Option may again be subjected to an
Option under this Plan, except that shares subject to purchase pursuant to any
Options or portion thereof relinquished and not required to be issued upon such
relinquishment shall not again be available for Options under this Plan.

5.  OPTION PRICE

    (a) The purchase price of each share of Stock subject to an incentive stock
option under this Plan shall be 100% of the fair market value of such share on
the date the Option is granted. The purchase price of each share of Stock
subject to a nonqualified stock option under this Plan shall be determined by
the Committee prior to granting the Option. The Committee shall set the
purchase price for each share subject to a nonqualified stock option at either
the fair market value of each share on the date the Option is granted, or at
such other price as the Committee in its sole discretion shall determine;
provided, however, that in no event shall the purchase price of a share subject
to a nonqualified stock option under this Plan be less than 50% of the fair
market value of such share on the date the Option is granted.

    (b) The fair market value of a share of Stock on a particular date shall be
deemed to be the average (mean) of the reported "high" and "low" sales prices
for such shares as reported in The Wall Street Journal's NYSE-Composite
Transactions listing for such day (corrected for obvious typographical errors),
or if such shares are not reported in such listing, then the average of the
reported "high" and "low" sales prices on the largest national securities
exchange (based on the aggregate dollar value of securities listed) on which
such shares are listed or traded, or if such shares are not listed or traded on
any national securities exchange, then the average of the reported "high" and
"low" sales prices for such shares in over-the-counter market, as reported on
the National Association of Securities Dealers Automated Quotations System, or,
if such prices shall not be reported thereon, the average between the closing
bid and asked prices so reported, or, if such prices shall not be reported,
then the average closing bid and asked prices reported by the National
Quotation Bureau Incorporated, or, in all other cases, the value established by
the Board of Directors of the Company in good faith.



                                     - 2 -
<PAGE>   3

6.  OPTION PERIOD

    Each Option granted under this Plan shall terminate and be of no force and
effect with respect to any shares not previously taken up by the Optionee upon
the expiration of ten years from the date of granting of such Option or such
earlier date as the Committee, in its sole discretion, may prescribe at the
date of grant.

7.  EXERCISE OF OPTIONS

    (a) The Committee, in granting Options hereunder, shall have discretion to
determine the terms upon which such Options shall be exercisable, subject to
the applicable provisions of this Plan. The Committee may determine to permit
any Option granted hereunder to be exercisable immediately upon the date of
grant or at any time thereafter; provided, however, that no Option granted
hereunder may be exercised within the first six months after the date of grant
except in the event of the death or disability of the Optionee.

    (b) Options may be exercised solely by the Optionee during his lifetime or
after his death by the person or persons entitled thereto under this will or
the laws of descent and distribution.

    (c) In the event of termination of employment for any reason other than
death, disability or retirement, Options may be exercised only with respect to
the number of shares purchasable at the time of such termination, unless the
Committee shall otherwise approve on a case by case basis.

    (d) In the event of the death or disability of the Optionee following the
date of grant and while in the employ of the Company or any of its affiliates,
and while Options granted hereunder are still in force and unexpired under the
terms of Paragraph 6, any unmatured installments of the Options shall be
accelerated. Such acceleration shall be effective as of the date of death or
disability, as the case may be. The Options outstanding in the name of the
Optionee shall thereupon be exercisable in full without regard to any
installment exercise provisions.

    (e) In the event the Optionee terminates his employment because of
retirement under any retirement plan of the Company or any of its Affiliates
while Options granted hereunder are still in force and unexpired under the
terms of Paragraph 6, the Committee shall have discretion to permit any
unmatured installments of the Options to be accelerated as of the date of
retirement and the Options shall thereupon be exercisable in full without
regard to any installment exercise provisions.

    (f) The purchase price of the shares as to which an Option is exercised
shall be paid in full at the time of the exercise. Such purchase price shall be
payable in cash (including certified check, bank draft and postal or express
money order payable to the order of the Company), or at the option of the
holder of such Option, in Common Stock theretofore owned by such holder (or any
combination of cash and Common Stock). For purposes of determining the amount,
if any, of the purchase price satisfied by payment of Common Stock, such Common
Stock shall be valued at its fair market value on the date of exercise in
accordance with Paragraph 5(b). Any Common Stock delivered in satisfaction of
all or a portion of the purchase price shall be appropriately endorsed for
transfer and assigned to the Company. The Committee may, in its discretion and
to the extent permitted by the laws of the State of Louisiana, determine to
permit the holder of an Option to satisfy the purchase price of the shares as
to which an Option is exercised by delivery of the Option holder's promissory
note, such note to be subject to such terms and conditions as the Committee may
determine. The Committee may, in its discretion and to the extent permitted by
the laws of the State of Louisiana, determine to cause the Company to lend to
the holder of an Option funds, on such terms and conditions as the Committee
may determine to be appropriate, sufficient for the holder of an Option to pay
the purchase price of the shares as to which an Option is to be exercised. No
holder of an Option shall be, or have any of the rights or privileges of, a
shareholder of the Company in respect of any shares purchasable upon the
exercise of any part of an Option unless and until certificates representing
such shares shall have been issued by the Company to such holder.

    (g) The option agreement evidencing any incentive stock option granted
under this Plan shall provide that if the Optionee makes a disposition, within
the meaning of Section 425(c) of the Code and the regulations promulgated
thereunder, of any share or shares of Stock issued to him pursuant to his
exercise of an Option granted under this Plan within the two-year period
commencing on the day after the date of the grant of such Option or within a
one-year period commencing on the day after the date of transfer of the share
or shares to him


                                     - 3 -
<PAGE>   4

pursuant to the exercise of such Option, he shall, within ten days of such
disposition, notify the Company thereof and immediately deliver to the Company
any amount of federal income tax withholding required by law.

8.  RELINQUISHMENT OF OPTIONS; ASSIGNABILITY

    (a) The Committee, in granting Options hereunder, shall have discretion to
determine whether or not Options shall include a right of relinquishment as
hereinafter provided by this Paragraph 8. The Committee shall also have
discretion to determine whether an option agreement evidencing an Option
initially granted by the Committee without a right of relinquishment shall be
amended or supplemented to include such a right of relinquishment. Neither the
Committee nor the Company shall be under any obligation to incur any liability
to any person by reason of the Committee's refusal to grant or include a right
of relinquishment in any Option granted hereunder or in any option agreement
evidencing the same. Subject to the Committee's determination in any case that
the grant by it of a right of relinquishment is consistent with Paragraph 1
hereof, any Option granted under this Plan, and the option agreement evidencing
such Option, may provide:

        (i) That the Optionee, or his heirs or other legal representatives to
    the extent entitled to exercise the Option under the terms thereof, in lieu
    of purchasing the entire number of shares subject to purchase thereunder,
    shall have the right to relinquish all or any part of the then unexercised
    portion of the Option (to the extent then exercisable) for a number of
    shares of Stock, for an amount of cash or for a combination of Stock and
    cash to be determined in accordance with the following provisions of this
    clause (i):

            (A) The written notice of exercise of such right of relinquishment
        shall state the percentage, if any, of the Appreciated Value (as
        defined below) that the Optionee elects to receive in cash ("Cash
        Percentage"), such Cash Percentage to be in increments of 10% of such
        Appreciated Value up to 100% thereof;

            (B) The number of shares of Stock of the Company, if any, issuable
        pursuant to such relinquishment shall be the number of such shares,
        rounded to the next greater number of full shares, as shall be equal to
        the quotient obtained by dividing (x) the difference between (I) the
        Appreciated Value and (II) the result obtained by multiplying the
        Appreciated Value and the Cash Percentage by (y) the then current
        market value per share of Stock;

            (C) The amount of cash payable pursuant to such relinquishment
        shall be an amount equal to the Appreciated Value less the aggregate
        current market value of the Stock issued pursuant to such
        relinquishment, if any, which cash shall be paid by the Company subject
        to such conditions as are deemed advisable by the Committee to permit
        compliance by the Company with the withholding provisions applicable to
        employers under the Code and any applicable state income tax laws; and

            (D) For the purposes of this clause (i), "Appreciated Value" means
        the excess of (x) the aggregate current market value of the shares of
        Stock covered by the Option or the portion thereof to be relinquished
        over (y) the aggregate purchase price for such shares specified in such
        Option;

        (ii) That such right of relinquishment may be exercised only upon
    receipt by the Company of a written notice of such relinquishment which
    shall be dated the date of election to make such relinquishment; and that,
    for the purposes of this Plan, such date of election shall be deemed to be
    the date when such notice is sent by registered or certified mail, or when
    receipt is acknowledged by the Company, if mailed by other than registered
    or certified mail or if delivered by hand or by any telegraphic
    communications equipment of the sender or otherwise delivered; provided,
    that, in the event the method just described for determining such date of
    election shall not be or remain consistent with the provisions of Section
    16(b) of the Exchange Act or the rules and regulations adopted by the
    Commission thereunder, as presently existing or as may be hereafter
    amended, which regulations exempt from the operation of Section 16(b) of
    the Exchange Act in whole or in part any such relinquishment transaction,
    then such date of election shall be determined by such other method
    consistent with Section 16(b) of the Exchange Act or the rules and
    regulations thereunder as the Committee shall in its discretion select and
    apply;



                                     - 4 -
<PAGE>   5

        (iii) That the "current market value" of a share of Stock on a
    particular date shall be deemed to be its fair market value on that date as
    determined in accordance with Paragraph 5(b); and

        (iv) That the Option, or any portion thereof, may be relinquished only
    to the extent that (A) it is exercisable on the date written notice of
    relinquishment is received by the Company, (B) the Committee, subject to
    the provisions of Paragraph 8(b), shall consent to the election of the
    holder to relinquish such Option in whole or in part for cash as set forth
    in such written notice of relinquishment and (C) the holder of such Option
    pays, or makes provision satisfactory to the Company for the payment of,
    any taxes which the Company is obligated to collect with respect to such
    relinquishment.

    (b) The Committee shall have sole discretion to consent to or disapprove,
and neither the Committee nor the Company shall be under any liability by
reason of the Committee's disapproval of, any election by a holder of an Option
to relinquish such Option in whole of in part for cash as provided in Paragraph
8(a).

    (c) The Committee, in granting Options hereunder, shall have discretion to
determine the terms upon which such Options shall be relinquishable, subject to
the applicable provisions of this Plan, and including such provisions as are
deemed advisable to permit the exemption from the operation from Section 16(b)
of the Exchange Act of any such relinquishment transaction, and Options
outstanding, and option agreements evidencing such Options, may be amended, if
necessary, to permit such exemption. If an Option is relinquished, such Option
shall be deemed to have been exercised to the extent of the number of shares of
Stock covered by the Option or part thereof which is relinquished, and no
further Options may be granted covering such shares of Stock.

    (d) Neither any Option nor any right to relinquish the same to the Company
as contemplated by this Paragraph 8 shall be assignable or otherwise
transferable except by will or the laws of descent and distribution.

    (e) No right of relinquishment may be exercised within the first six months
after the initial award of any Option containing, or the amendment or
supplementation of any existing option agreement adding, the right of
relinquishment; provided, however, that this limitation shall not apply in the
event of death or disability.

9.  STOCK DIVIDENDS, STOCK SPLITS AND CERTAIN OTHER CORPORATION TRANSACTIONS

    (a) The existence of this Plan and Options granted hereunder shall not
affect in any way the right or power of the Company or its shareholders to make
or authorize any or all adjustments, recapitalizations, reorganizations or
other changes in the Company's capital structure or its business, or any merger
or consolidation of the Company, or any issue of bonds, debentures or preferred
or preference stocks ranking prior to or affecting the Common Stock or the
rights attendant thereto, or the dissolution or liquidation of the Company, or
any sale or transfer of all or any part of the Company's assets or business, or
any other corporate act or proceeding, whether of a similar character or
otherwise.

    (b) The shares with respect to which Options may be granted hereunder are
shares of Common Stock of the Company as presently constituted. If, and
whenever, prior to the deliver by the Company of all of the shares of the Stock
which are subject to Options granted hereunder, the Company shall effect a
subdivision or consolidation of shares or other capital readjustment, the
payment of a stock dividend, a stock split, a combination of shares, a
recapitalization or other increase or reduction of the number of shares of the
Common Stock outstanding without receiving consideration therefor in money,
services or property, the number of shares of Stock available under this Plan
and the number of shares of Stock with respect to which Options granted
hereunder may thereafter be exercised shall (i) in the event of an increase in
the number of outstanding shares, be proportionately increased, and the cash
consideration payable per share shall be proportionately reduced, and (ii) in
the event of a reduction in the number of outstanding shares, be
proportionately reduced, and the cash consideration payable per share shall be
proportionately increased.

    (c) If the Company is reorganized, merged or consolidated or is otherwise a
party to a plan of exchange with another corporation pursuant to which
reorganization, merger, consolidation or plan of exchange shareholders of the
Company receive any shares of common stock or other securities or if the
Company shall distribute ("Spin Off") securities of another corporation to its
shareholders, there shall be substituted for the shares subject to the
unexercised portions of outstanding Options an appropriate number of shares of
(i) each class of stock or other



                                     - 5 -

securities which were distributed to the shareholders of the Company in respect
of such shares in the case of a reorganization, merger, consolidation or plan
of exchange, or (i) in the case of a Spin Off, the securities distributed to
shareholders of the Company together with shares of Stock, such number of
shares or securities to be determined in accordance with the provisions of
Section 425 of the Code (or other applicable provisions of the Code or
regulations issued thereunder which may from time to time govern the treatment
of incentive stock options in such a transaction); provided, however, that all
such Options may be cancelled by the Company as of the effective date of (x) a
reorganization, merger, consolidation, plan of exchange or Spin Off or (y) any
dissolution or liquidation of the Company, by giving notice to each holder
thereof or his personal representative of its intention to do so and by
permitting the purchase for a period of at least thirty days during the sixty
days next preceding such effective date of all of the shares subject to such
outstanding Options, without regard to the installment provisions set forth in
the option agreements; and provided further that in the event of a Spin Off,
the Company may, in lieu of substituting securities or accelerating and
cancelling Options as contemplated above, elect (i) to reduce the purchase
price for each share of Stock subject to an outstanding Option by an amount
equal to the fair market value, as determined in accordance with the provisions
of Paragraph 5(b), of the securities distributed in respect of each outstanding
share of Common Stock in the Spin Off or (ii) to reduce proportionately the
purchase price per share and to increase proportionately the number of shares
of Stock subject to each Option in order to reflect the economic benefits
inuring to the shareholders of the Company as a result of the Spin Off.

    (d) Except as hereinbefore expressly provided, the issue by the Company of
shares of stock of any class, or securities convertible into or exchangeable
for shares of stock of any class, for cash or property, or for labor or
services, either upon direct sale or upon the exercise of rights or warrants to
subscribe therefor, or upon conversion of shares of obligations of the Company
convertible into or exchangeable for shares of stock of any class shall not
affect, and no adjustment by reason thereof shall be made with respect to, the
number of shares of Stock subject to Options granted hereunder.

(e) The Committee may, in its sole discretion, provide that an Option shall
    become fully exercisable upon a Change in Control of the Company (as
    defined in the next sentence). "Change in Control" of the Company shall be
    conclusively deemed to have occurred if (and only if) any of the following
    shall have taken place: (i) a change in control is reported by the Company
    in response to either Item 6(e) of Schedule 14A of Regulation 14A
    promulgated under the Exchange Act or Item 1 of Form 8-K promulgated under
    the Exchange Act; (ii) any "person" (as such term is used in Sections 13(d)
    and 14(d) (2) of the Exchange Act) is or becomes the "beneficial owner" (as
    defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
    securities of the Company representing forty percent or more of the
    combined voting power of the Company's then outstanding securities; or
    (iii) following the election or removal of directors, a majority of the
    Board consists of individuals who were not members of the Board two years
    before such election or removal, unless the election of each director who
    was not a director at the beginning of such two-year period has been
    approved in advance by directors representing at least a majority of the
    directors then in office who were directors at the beginning of the
    two-year period. Not withstanding the foregoing, the Committee is
    prohibited from exercising its discretion to accelerate the exercisability
    of options upon a Change in Control if such action would preclude the use
    of the pooling of interests method of accounting for the combination of Not
    withstanding the foregoing, the Committee is prohibited from exercising its
    discretion to accelerate the exercisability of options upon a Change in
    Control if such action would preclude the use of the pooling of interests
    method of accounting for the combination of business interests.
    Notwithstanding the foregoing, the Committee is prohibited from exercising
    its discretion to accelerate the exercisability of options upon a Change in
    Control if such action would preclude the use of the pooling of interests
    method of accounting for the combination of business interests.

(f) 10.  PURCHASE FOR INVESTMENT

    Unless the Options and shares of Stock covered by this Plan have been
registered under the Securities Act of 1933, as amended, or the Company has
determined that such registration is unnecessary, each person exercising an
Option under this Plan may be required by the Company to give a representation
in writing that he



                                     - 6 -
<PAGE>   7
is acquiring such shares for his own account for investment and not with a view
to, or for sale in connection with, the distribution of any part thereof.

11. TAXES

    (a) The Company may make such provisions as it may deem appropriate for the
withholding of any taxes which it determines is required in connection with any
Options granted under this Plan.

    (b) Notwithstanding the terms of Paragraph 11(a), any Optionee may pay all
or any portion of the taxes required to be withheld by the Company or paid by
him in connection with the exercise of a nonqualified Option by electing to
have the Company withhold shares of Stock, or by delivering previously owned
shares of Common Stock, having a fair market value, determined in accordance
with Paragraph 5(b), equal to the amount required to be withheld or paid. An
Optionee must make the foregoing election on or before the date that the amount
of tax to be withheld is determined ("Tax Date"). All such elections are
irrevocable and subject to disapproval by the Committee. Elections by persons
who are subject to the short-swing profits recapture provisions of Section
16(b) of the Exchange Act ("Covered Optionees") are subject to the additional
restriction that such election may not be made within six months of a grant of
an Option, provided that this limitation shall not apply in the event of death
or disability. Where the Tax Date in respect of an Option is deferred until six
months after exercise and the Covered Optionee elects share withholding, the
full amount of shares of Common Stock will be issued or transferred to him upon
exercise of the Option, but he shall be unconditionally obligated to tender
back to the Company the number of shares necessary to discharge the Company's
withholding obligation or his estimated tax obligation on the Tax Date.

12. EFFECTIVE DATE OF PLAN

    This Plan shall be effective as of November 16, 1989.

13. AMENDMENT OR TERMINATION

    The Board of Directors may amend, alter or discontinue this Plan, except
that no amendment or alteration shall be made which would impair the rights of
any Optionee under any Option theretofore granted, without his consent, and
except that no amendment or alteration shall be made which, without the
approval of the shareholders, would:

        (a) Increase the total number of shares reserved for the purposes of
    this Plan or decrease the option price provided for in Paragraph 5, except
    in each case as provided in Paragraph 9, or change the class of employees
    eligible to participate in this Plan as provided in Paragraph 3;

        (b) Extend the option period provided for in Paragraph 6;

        (c) Materially increase the benefits accruing to Optionees under this
    Plan;

        or

        (d) Materially modify the requirements as to eligibility of
    participation in this Plan.

14. GOVERNMENT REGULATIONS

    This Plan, and the grant and exercise of Options thereunder, and the
obligation of the Company to sell and deliver shares under such Options, shall
be subject to all applicable laws, rules and regulations, and to such approvals
by any governmental agencies or national securities exchanges as may be
required.

                            SPECIAL SEVERANCE PROGRAM


1.       Employees Covered. The Special Severance Program (the "Program") shall
         cover all salaried employees of SOUTHDOWN, INC. (the "Company"), and
         its subsidiaries, other than employees covered by individual severance
         or employment agreements. For purposes of this Program, the term
         "salaried employees" shall mean those employees who are permanent
         full-time employees and who are compensated with a salary of a set
         amount for a standard number of hours per pay period rather than
         hourly. Individuals in this category will include all individuals
         designated "exempt" from provisions of the Fair Labor Standards Act as
         well as those individuals designated "non-exempt" under that Act who
         are paid on a salaried basis, even though eligible for overtime
         payments.

2.       Condition to Benefits Being Payable. No benefits shall be payable under
         the Program unless (i) there shall have been a Change in Control of the
         Company, and (ii) the salaried employee's employment with the Company
         and its subsidiaries is terminated within eighteen months after the
         date of the Change of Control of the Company, for reasons other than
         death, Retirement, Disability, Cause or termination by the employee
         other than for Good Reason. For purposes of this Program, a Change in
         Control of the Company shall be conclusively deemed to have occurred if
         (and only if) any of the following shall have taken place: (i) a change
         in control is reported by the Company in response to either Item 6(e)
         of Schedule 14A of Regulation 14A promulgated under the Securities
         Exchange Act of 1934, as amended ("Exchange Act"), or Item 1 of Form
         8-K promulgated under the Exchange Act; (ii) any "person" (as such term
         is used in Sections 13(d) and 14(d)(2) of the Exchange Act) is or
         becomes the "beneficial owner" (as defined in Rule 13d-3 under the
         Exchange Act), directly or indirectly, of securities of the Company
         representing forty percent or more of the combined voting power of the
         Company's then outstanding securities; or (iii) following the election
         or removal of directors, a majority of 










<PAGE>   2


         the Board consists of individuals who were not members of the Board two
         years before such election or removal, unless the election of each
         director who was not a director at the beginning of such two-year
         period has been approved in advance by directors representing at least
         a majority of the directors then in office who were directors at the
         beginning of the two-year period.

         For purposes of this Program, "Retirement" shall mean termination of
         employment in accordance with the retirement policy of the Company or
         the subsidiary for which the employee works; "Disability" shall mean
         the absence of an employee from his or her duties with the Company or
         its subsidiaries on a full-time basis for six consecutive months and
         the failure of the employee to return to the full-time performance of
         his or her duties within thirty days after written notice of
         termination is given to the employee; and "Cause" shall mean the
         willful and continued failure by an employee to substantially perform
         his or her duties with the Company or its subsidiaries (other than any
         such failure resulting from the employee's incapacity due to physical
         or mental illness) after a demand for substantial performance is
         delivered to the employee by his or her appropriate supervisor or the
         willful engaging by the employee in conduct which is demonstrably and
         materially injurious to the Company or its subsidiaries, monetarily or
         otherwise.

         For purposes of this Program, "Good Reason" shall mean (i) a
         substantial adverse alteration in the nature or status of an employee's
         responsibilities from those in effect immediately prior to the Change
         in Control of the Company, (ii) a reduction by the Company or its
         subsidiaries in the employee's annual base salary or, if applicable,
         commission or bonus potential, (iii) the failure of the Company or its
         subsidiaries to provide the employee with benefits generally comparable
         to those provided to the employee immediately prior to the Change in
         Control of the Company, (iv) the relocation of the employee's place of
         employment to a place more than 20 miles from where it was immediately
         prior to the Change in Control of the Company, or (v) the failure of
         the 



                                       2




<PAGE>   3


         Company or its subsidiaries to pay to the employee any amounts due and
         owing to him or her or the breach by the Company or its subsidiaries of
         any other material legal obligation to such employee.

3.       Benefits. A salaried employee whose employment is terminated as
         provided in clause (ii) of the first sentence of Section 2, and
         provided that a Change in Control has occurred, shall receive the
         following benefits:

         A.       A salaried employee who immediately prior to the Change in
                  Control of the Company had a base salary of at least $60,000
                  per year shall continue to receive from the Company or its
                  subsidiaries amounts equal to his or her base salary as in
                  effect immediately prior to the Change in Control of the
                  Company for up to eighteen months from the date of termination
                  of employment or until the employee begins new employment,
                  whichever is sooner, and for said period shall continue to be
                  covered under the medical, dental, life insurance and accident
                  benefit programs in effect and applicable to the employee
                  immediately prior to the time of the Change in Control of the
                  Company. If the new employment pays a base salary less than
                  the base salary the employee was earning immediately prior to
                  the Change in Control of the Company, the Company or its
                  subsidiaries will pay the employee the difference for up to
                  six months from the commencement of new employment; provided,
                  however, that the total amount of salary continued and
                  supplemented (but not including the cost of benefits) shall
                  not exceed an amount equal to eighteen months' base salary.

         B.       A salaried employee not covered by Paragraph A above shall be
                  entitled to receive the same benefits as provided in Paragraph
                  A above, except that the reference therein to 



                                       3


<PAGE>   4


                  "eighteen months" or "eighteen months'" shall be deemed to be
                  "nine months" or nine months'", respectively.

         C.       (i) A salaried employee qualifying under Paragraph A shall
                  also be entitled to individual outplacement service which is
                  appropriate to the employee's position, as determined from
                  time to time by the Administrative Committee. (ii) A salaried
                  employee not covered by (i) above shall be entitled to group
                  outplacement service which is appropriate to the employee's
                  position, as determined from time to time by the
                  Administrative Committee.

         D.       Benefits provided to any employee under this Section 3 shall
                  be reduced by any severance payments made by the Company or
                  its subsidiaries to such employee otherwise than pursuant to
                  this Program. Unemployment compensation benefits are not
                  deemed to be payments made by the Company or its subsidiaries.

4.       Administration.

         A.       The general administration of the Program, and the
                  responsibility for carrying out the provisions hereof, shall
                  be placed in an Administrative Committee appointed by the
                  Board of Directors of the Company.

         B.       The members of the Administrative Committee shall select one
                  of their members as chairman and shall also elect a secretary
                  who may, but need not, be a member of the Administrative
                  Committee; and may authorize one or more of their number or
                  any agent to execute or deliver any instrument or make any
                  payment in their behalf, and may employ such clerical
                  personnel as they may require in carrying out the provisions
                  of the Program. 




                                       4


<PAGE>   5



         C.       The Administrative Committee shall hold meetings upon such
                  notice, at such place or places, and at such time or times as
                  they may from time to time determine. A majority of the
                  Administrative Committee may act by meeting (whether in person
                  or by telephone) or by writing executed without a meeting.

         D.       The Administrative Committee shall have complete control of
                  the administration of the Program, with all powers necessary
                  to enable it to properly carry out its duties in that respect.
                  The Administrative Committee shall be authorized to interpret
                  this Program and to determine all questions arising in the
                  administration, construction and application of the Program.
                  The decision of the Administrative Committee upon all matters
                  within the scope of its authority shall be conclusive and
                  binding on all parties.

         E.       Subject to the limitations of this Section 4, the
                  Administrative Committee from time to time shall establish
                  supplemental rules and regulations for the administration of
                  the Program and the transaction of its business as it deems
                  necessary.

         F.       The Administrative Committee shall be responsible for the
                  preparation and delivery of all reports, notices, plan
                  summaries and plan descriptions required to be filed with any
                  governmental office or to be given to any employee or
                  beneficiary of any employee covered by this Program.

         G.       Upon request of the Administrative Committee, the Company or
                  any of its subsidiaries shall furnish such information in its
                  possession as will aid the Administrative Committee in the
                  performance of its duties hereunder.

5.       Claims Procedure.

         A.       All claims for benefits shall be in writing and shall be filed
                  with the Administrative Committee.

         B.       If the Administrative Committee wholly or partially denies a
                  former employee's claim for benefits, the Administrative
                  Committee shall give the claimant written notice within sixty
                  (60) days after the Program's receipt of the claim setting
                  forth:

                  (i)    the specific reason(s) for the denial;

                  (ii)   specific reference to pertinent Program provisions on
                         which the denial is based;

                  (iii)  a description of any additional material or information
                         which must be submitted to perfect the claim, and an
                         explanation of why such material or information is
                         necessary; and

                  (iv)   an explanation of the Program's review procedure.

         C.       In the event of a benefit claim denial, the Company shall
                  appoint a person who is not a member of the Administrative
                  Committee to serve as Claim Reviewer. The person designated as
                  the Claim Reviewer shall be reasonably acceptable to the
                  claimant. The claimant shall have sixty (60) days after the
                  day on which such written notice of denial is handed or mailed
                  to him or her by the Administrative Committee in which to
                  apply (in person or by authorized representative) in writing
                  to the Claim Reviewer for a full and fair review of the denial
                  of his or her claim. In connection with such review, the
                  claimant (or his or her representative) shall be afforded a
                  reasonable opportunity to review pertinent documents, and may
                  submit issues and comments in writing. The Claim Reviewer
                  shall arrange to meet personally with the claimant and/or
                  representative within thirty (30) days after the Claim
                  Reviewer's receipt of such written request for review for 



                                       6


<PAGE>   7


                  the purpose of hearing the claimant's contentions and
                  receiving such relevant evidence as the claimant may wish to
                  offer.

         D.       The Claim Reviewer shall issue his decision on review within
                  sixty (60) days after meeting with the claimant or claimant's
                  personal representative, unless in the sole discretion of the
                  Claim Reviewer special circumstances require an extension to
                  not later than one hundred twenty (120) days after such
                  meeting. The decision shall be in writing and shall set forth
                  specific reasons for the decision and specific references to
                  pertinent Plan provisions on which the decision is based.

         E.       The Company or its subsidiary shall pay the costs and
                  expenses, including without limitation, reasonable attorneys'
                  fees, incurred by an employee in seeking to enforce his or her
                  rights under the Program.

6.       Employment of Professional Assistance. The Administrative Committee is
         empowered, on behalf of the Program, to engage accountants, legal
         counsel and such other personnel as it deems necessary or advisable to
         assist it in the performance of its duties under the Program. The
         functions of any such persons engaged by the Administrative Committee
         shall be limited to the specific services and duties for which they are
         engaged, and such persons shall have no other duties, obligation or
         responsibilities under the Program. Such persons shall exercise no
         discretionary authority or discretionary control respecting the
         management of the Program. All reasonable expenses thereof shall be
         borne by the Company.

                         SUPPLEMENTAL PENSION AGREEMENT


         AGREEMENT made as of the 1st day of April 1980, by and between
SOUTHDOWN, INC., a Louisiana corporation having its principal place of business
at Two Allen Center, Suite 2200, Houston, Texas  77002 (the "Company"), and
___________, residing at ________________________________________________ (the
"Executive").

                             W I T N E S S E T H :

         WHEREAS, the Executive has been a valued key executive of the Company
with many years of devoted and distinguished service; and

         WHEREAS, in order to induce the Executive to continue his employment
with the Company, the Company desires to supplement the retirement income of
the Executive and to provide certain other benefits for the Executive, all on
the terms and conditions hereinafter set forth;

         NOW, THEREFORE, the Company and the Executive hereby agree as follows:

         1.      Termination of Employment At or After Age 65; Survivor's
                 Benefits

                 (a)      Upon the termination of the Executive's employment
after he attains the age 65 for any reason other than death, the Executive
shall receive a "Supplemental Pension", payable for his life, commencing on the
first day of the calendar month following the month in which the Executive's
employment terminates.  For purposes of this Section 1, a "Supplemental
Pension" shall mean monthly pension in an annual amount equal to the excess (if
any) of (1) 60% of Compensation [as defined in Section 11(d)], over (2) Other
Retirement Benefits [as defined in Section 11(f)] expressed as an annual
amount.

                 (b)      Upon the death of the Executive while entitled to
receive a Supplemental Pension pursuant to Section 1(a), and provided the
Executive has not received 120 monthly payments thereunder prior to his death,
the Company shall make the same monthly payments to his Beneficiary that the
<PAGE>   2
Executive was entitled to receive under Section 1(a) until an aggregate of 120
monthly payments have been made to the Executive and/or his Beneficiary.

                 (c)      Upon the death of the Executive after he attains age
65 and while employed by the Company, the Company shall pay to his Beneficiary
a Supplemental Pension calculated in accordance with Section 1(a), payable for
a period of 120 months, commencing on the first day of the calendar month
following the month in which the Executive died.

         2.      Termination of Employment Prior to Age 65; Survivor's
                 Benefits.

                 (a)      Upon the termination of the Executive's employment
before he attains age 65 for any reason other than death or Disability, the
Executive shall receive a Supplemental Pension, payable for his life,
commencing on the first day of the calendar month following the month in which
the Executive attains age 65 (the "Deferred Pension Commencement Date").  For
purposes of this Section 2, a "Supplemental Pension" shall mean a monthly
pension in an annual amount equal to the excess (if any) of (1) 60% of
Compensation [as defined in Section 11(d)] multiplied by a fraction, the
numerator of which is the number of full months of completed service by the
Executive in the employ of the Company during the period (the "Vesting Period")
between March 31, 1980 and the date on which the Executive will attain (or, if
the Executive dies before attaining age 65, would have attained) age 65 and the
denominator of which is the number of full months contained in the Vesting
Period, over (2) Other Retirement Benefits [as defined in Section 11(f)]
expressed as an annual amount.

                 (b)      In the event the Executive should die after
termination of his employment but before the Deferred Pension Commencement
Date, then the Company shall pay to his Beneficiary a Supplemental Pension
calculated in accordance with Section 2(a), payable for a period of 120 months,
commencing on the Deferred Pension Commencement Date.

                 (c)      Upon the death of the Executive while receiving a
Supplemental Pension pursuant to Section 2(a), and provided the Executive has
not received 120 monthly payments thereunder prior to his death, the Company
shall make the same monthly payments to his Beneficiary that the




                                      2
<PAGE>   3
Executive was entitled to receive under Section 2(a) until an aggregate of 120
monthly payments have been made to the Executive and/or his Beneficiary.

                 (d)      Upon the death of the Executive before he attains age
65 and while employed by the Company, the Company shall pay to his Beneficiary
a Supplemental Pension calculated in accordance with Section 2(a), payable for
a period of 120 months, commencing on the first day of the calendar month
following the month in which the Executive died; provided, however, that in
computing a Supplemental Pension payable pursuant to this Section 2(d), the
fraction referred to in the definition of "Supplemental Pension" in Section
2(a) shall be deemed to be equal to "one".

         3.      Disability Benefits; Survivor's Benefits.

                 (a)      Upon the termination of the Executive's employment as
a result of a Disability before he attains age 65, the Executive shall receive,
in lieu of any and all amounts receivable by him under Section 1 or 2 hereof, a
Disability Pension, payable for his life, commencing on the first day of the
calendar month following the month in which the Executive's employment
terminates because of his Disability.  A "Disability Pension" shall mean a
monthly pension in an annual amount equal to the excess (if any) of (1) 60% of
the greater of (x) Executive's annual base salary (excluding incentive or bonus
compensation and fringe benefits) during the last complete calendar year prior
to his Disability, and (y) Executive's rate of annual base salary (excluding
incentive or bonus compensation and fringe benefits) in effect immediately
prior to his Disability, over (2) the monthly amount of the Executive's Other
Disability Benefits [as defined in Section 11(g)].

                 (b)      Upon the death of the Executive while entitled to
receive a Disability Pension pursuant to Section 3(a), and provided the
Executive has not received 120 monthly payments prior to his death, the Company
shall make the same monthly payments to his Beneficiary that the Executive was
entitled to receive under Section 3(a) until an aggregate of 120 monthly
payments have been made to the Executive and/or his Beneficiary.

         4.      Administration.  This Agreement shall be administered on
behalf of the Company by its Board of Directors.  The Board of Directors may
delegate its duties to any committee designated by it for




                                      3
<PAGE>   4
such purpose.  The Board of any such committee shall have the authority to
interpret, and to determine questions of fact arising under, this Agreement,
including, without limitation, whether a Disability exists, whether the
Executive's employment has been terminated as a result of a Disability and
whether there has been a forfeiture as defined in Section 6, and shall be
entitled to rely on all records of the Company in connection therewith.  The
determination of the Board of Directors or any committee administering this
Agreement shall be conclusive and binding upon the Executive, the Beneficiary
and the Company.

         5.      Cooperation; Estoppel of the Executive and the Beneficiary;

                 (a)      The Executive shall furnish the Company with all
information which the Company may deem necessary or desirable to assist it in
the administration of this Agreement, including, without limitation, any
information necessary or desirable in computing the amount of the Executive's
Plan Benefits payable by any person other than the Company.

                 (b)      The Company, its Board of Directors or any committee
thereof may rely upon any certificate, statement or other representation made
to them by the Executive with respect to age, length of service, designated
Beneficiary, date of commencement or termination of employment, or other fact
required to be determined under any of the provisions of this Agreement, and
shall not be liable on account of the payment of any moneys or the doing of any
act in reliance upon any such certificate, statement or other representation.
Any such certificate, statement of other representation made by the Executive
shall be conclusively binding upon the Executive and his Beneficiary, and the
Executive and his Beneficiary shall thereafter and forever be estopped from
disputing the truth and correctness of such certificate, statement or other
representation.

         6.      Forfeiture.  Notwithstanding anything contained in this
Agreement, if the employment of the Executive is terminated for fraud or
dishonesty, then all rights which the Executive or his Beneficiary may have
under this Agreement shall be forfeited, and any liability of the Company to
make payments hereunder shall terminate.

         7.      Non-Competition.  So long as the Executive is employed by the
Company, and during any period the Executive is receiving a Supplemental
Pension or Disability Pension pursuant to this




                                      4
<PAGE>   5
Agreement, the Executive shall not, directly or indirectly, as an officer,
director, employee, consultant, agent, stockholder, partner or otherwise,
participate in or be employed by any person, firm or corporation which is
engaged in any business which competes in any material respect with a material
portion of the business of the Company or any of its subsidiaries or
affiliates; provided, however, that nothing in this Section 7 shall prevent the
Executive from owning not more than 2% of the outstanding equity securities of
any corporation that is listed on any national securities exchange or actively
traded in the over-the-counter market.  The provisions of this Section 7 shall
constitute an independent and severable covenant and any court construing the
same shall have the power to modify, alter or reduce the scope of such
provisions in order to make them enforceable under applicable law.  In the
event the Executive breaches the provisions of this Section 7, he shall forfeit
all rights which he or his Beneficiary may have under this Agreement, whereupon
the obligation of the Company to make payments hereunder shall terminate.

         8.      Right to Terminate Employment.  Nothing in this Agreement
shall confer upon the Executive the right to continue in the employ of the
Company or affect any right the Company may have to terminate the Executive's
employment.

         9.      Assignment.  The Executive may not assign, pledge or otherwise
encumber his interest in this Agreement without the written consent of the
Company.  In the event of any sale or other disposition of all or a substantial
part of the assets of the Company, adequate provision, by a written assumption
agreement or otherwise, shall be made to secure for the Executive all of the
benefits of this Agreement to the same extent to which the Executive would have
been entitled to such benefits had any such disposition not taken place.

         10.     Rights to Third Parties.  The Executive and the Company may
amend this Agreement by a document in writing which may have the effect of
diminishing or eliminating benefits payable to his Beneficiary under the
several provisions of this Agreement.

         11.     Definitions.  Whenever used in this Agreement, the following
terms shall have the meanings ascribed to them in this Section:




                                      5
<PAGE>   6
                 (a)      Agreement.  "Agreement" shall mean this agreement, as
amended from time to time.

                 (b)      Beneficiary.  "Beneficiary" shall mean one or more
beneficiaries (who may be any one or more members of the Executive's family or
other persons, executors, administrators, any trust, foundation or other
entity) designated by the Executive in writing to the Company to receive such
amounts as may be payable under this Agreement after the Executive's death.
The Executive may also, in the same manner, and at any time and from time to
time, change any Beneficiary previously designated by him, without notice to,
or consent of, any previously designated Beneficiary.  If the Executive shall
fail validly to designate a Beneficiary, the Beneficiary shall be his surviving
spouse, or if none, his estate.  If any individual named as a Beneficiary shall
fail to survive the Executive, the Beneficiary shall be such alternate
Beneficiary as may have been named by the Executive, or, if none, shall be the
Executive's surviving spouse, or, if not spouse survives the Executive, his
estate.  No designation by the Executive of any person other than his spouse
shall be valid without the consent of such spouse.  For the purposes of the
immediately preceding sentence, a "spouse" shall mean any person who, under
applicable community property laws, shall be required to consent to such
designation in order for such designation to be fully effective.

                 (c)      Company.  The "Company" shall mean Southdown, Inc.
and any of its subsidiaries.

                 (d)      Compensation.  "Compensation" shall mean the average
of the fixed base annual salary paid by the Company to the Executive (excluding
incentive or bonus compensation and fringe benefits) during each of the five
calendar years of highest fixed base salary during which he was employed by the
Company (whether or not such five calendar years are consecutive and whether or
not the Executive was employed during all or part of any such calendar year).

                 (e)      Disability.  "Disability" shall mean an incapacity
which would entitle the Executive to benefits under the Company's group
disability insurance, or, if the opinion of the Board of Directors of the
Company, prevents the Executive from performing his customary duties and is
likely to




                                      6
<PAGE>   7
be permanent or of long duration.  If the Executive incurs a Disability, his
employment shall be treated as terminated for Disability on the first day on
which he is no longer covered by the Company's group life insurance program (or
any successor program thereto) by reason of his Disability.

                 (f)      Other Retirement Benefits.

                          (i)     With respect to a Supplemental Pension
payable pursuant to Section 1(a) or 1(b), "Other Retirement Benefits" shall
mean (x) all amounts paid to the Executive as Plan Benefits following his
attainment of age 65, and all amounts which, if the Executive had so chosen,
could have been so paid assuming he was then retired from all employment with
all current or former employers, plus (y) the Social Security Benefits payable
beginning at age 65, each expressed as an aggregate annual amount.

                          (ii)    With respect to a Supplemental Pension
payable pursuant to Section 2(a), 2(b) or 2(c), "Other Retirement Benefits"
shall mean (x) all amounts paid to the Executive as Plan Benefits following his
attainment of age 65, and all amounts which, if the Executive had so chosen,
could have been so paid assuming he was then retired from all employment with
all current or former employers (or, if the Executive dies before he attains
age 65, all amounts which, had the Executive been alive and so chosen, could
have been so paid to the Executive at age 65), plus (y) the Social Security
Benefits payable beginning at age 65, each expressed as an aggregate annual
amount.

                          (iii)   With respect to a Supplemental Pension
payable pursuant to Section 1(c) or 2(d), "Other Retirement Benefits" shall
mean (x) all amounts which, had the Executive been alive and so chosen, could
have been paid to the Executive as Plan Benefits following his attainment of
age 65 (computed on the assumption that the Executive's employment with the
Company terminated (for reasons other than his death or Disability) on the
earlier of his attainment of age 65 or the date of his death) plus (y) the
Social Security Benefits payable beginning at age 65, each expressed as an
aggregate annual amount such.

                          (iv)    If any Plan Benefits are paid or payable
otherwise than as a life annuity beginning at age 65 with a ten year certain
provision, then for the purpose of calculating a Supplemental




                                      7
<PAGE>   8
Pension, such payments shall be converted into the actuarial equivalent of a
life annuity beginning at age 65 with a ten year certain provision, based on
such assumptions, including assumptions as to interest rate and mortality, as
the Company may determine in its sole discretion.

                 (g)      Other Disability Benefits.  "Other Disability
Benefits" shall mean (i) all amounts paid to the Executive as Plan Benefits
following the date his employment terminates because of a Disability, and all
amounts which, had the Executive so chosen, could have been so paid, plus (ii)
the Social Security Benefits payable at the end of any applicable waiting
period; provided, however, that if, at the time the Executive's employment
terminated because of a Disability, he could not, if he so chose, obtain any or
all amounts payable under subclauses (i) of (ii) of this Section 11(g), then
any such amounts shall be deducted commencing as of the first day on which he
would be (or, if the Executive dies while entitled to receive a Disability
Pension hereunder, would have been) entitled to obtain such benefits; it being
further provided that any Plan Benefits or Social Security Benefits that are
limited in duration (other than on account of death) shall cease to be included
as Other Disability Benefits at such time as such benefits cease to be payable.

                 (h)      Plan Benefits.  "Plan Benefits" shall mean amounts
payable to the Executive under any disability, pension, profit-sharing,
retirement or deferred compensation plan (other than Social Security Benefits)
contributed to or maintained by the Company or any other prior or subsequent
employer (whether or not related to the Company), including any governmental
plans providing old age, retirement or disability benefits, except to the
extent such amounts are solely attributable to contributions by the Executive
to a defined contribution plan (or to contributions by the Executive to a
defined benefit plan to the extent such contributions provide benefits in the
nature of a defined contribution plan), and any amounts payable as retirement
or disability benefits under a contract between any such person or entity
(other than the Executive) and the Executive.

                 (i)      Social Security Benefits.  "Social Security Benefits"
shall mean amounts payable to the Executive under Retirement and Survivors
Insurance and Disability Insurance under the Federal Social Security Act or
corresponding provisions of subsequent law.  In applying the definition of
Other




                                      8
<PAGE>   9
Retirement Benefits and Other Disability Benefits, the Board of Directors of
the Company or any committee designated by the Board is hereby granted full
authority to adopt all such rules and assumptions which may be necessary or
desirable for purposes of determining the amount of an Executive's Social
Security Benefits, and all rules and assumptions so adopted shall be binding on
the Executive and his Beneficiary.  In determining the Executive's Supplemental
Pension, the Board shall compute such benefits by disregarding any event
(including, without limitation, continued employment or earnings, waiver or
failure to claim benefits, failure to survive until age 65, or reduction of
benefits at age 65 because of the earlier commencement thereof) which might
cause the Executive not actually to receive such benefit beginning at age 65.

         12.     Severability.  The provisions of this Agreement are severable,
and if any provision of this Agreement shall be held invalid or unenforceable,
such invalidity or unenforceability shall attach only to such provision and
shall not in any manner affect or render invalid or unenforceable any other
severable provision of this Agreement, and this Agreement shall be carried out
as if any such invalid or unenforceable provision were not contained herein.

         13.     Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas (without regard to
principles of conflict of laws).

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first above written.

                                        SOUTHDOWN, INC.

                 (i)      if Executive's employment terminates after he attains
age 61, and if such termination of employment is for any reason other than the
Executive's voluntary termination of employment without the Company's consent
(provided, however, that such consent shall not be required if such resignation
occurs following a breach by the Company of any employment agreement between
the Company and the Executive) his Supplemental Pension shall commence on the
first day of the month following the date on which the Executive's employment
terminates, or

                 (ii)     if (i) above is not applicable and if Executive's

                                                                    EXHIBIT 10.6


                              EMPLOYMENT AGREEMENT

         This Employment Agreement ("Agreement") is entered into between
Southdown, Inc., a Louisiana corporation ("Company"), and [Executive], a
resident of [Address] County, Texas ("Executive"), effective as of [Date]. The
Company and the Executive are sometimes referred to herein as the "Parties."

         1. Introduction. In connection with the revision of existing employment
agreements, the Company believes that the assurance of the Executive's continued
employment by the Company and the benefit of his business experience are of
material importance. Therefore, the Company and the Executive intend by this
Agreement to rescind any existing employment agreement and to specify the terms
and conditions of the Executive's continuing employment relationship with the
Company.

         2. Employment. The Company hereby employs the Executive and the
Executive hereby accepts continuing employment with the Company upon the terms
and conditions set forth herein.

         3. Duties and Responsibilities.

            3.1. Extent of Service. The Executive shall, during the term of this
Agreement, devote such of his entire time, attention, energies and business
efforts to his duties as an executive of the Company as are reasonably necessary
to carry out his duties specified in Paragraph 3.2 below. The Executive shall
not, during the term of this Agreement, engage in any other business activity
(whether or not such business activity is pursued for gain, profit or other
pecuniary advantage) if such business activity would impair the Executive's
ability to carry out his duties hereunder. This Paragraph 3.1, however, shall
not be construed to prevent the Executive from investing his personal assets as
a passive investor in such form or manner as will not contravene the Company's
Statement of Policy Regarding Corporate Ethics and Conflicts of Interest
("Policy Statement").

            3.2. Position and Duties. Subject to the power of the Board of
Directors of the Company to elect and remove officers, the Executive shall serve
the Company as [Executive Position] (or in such other office of comparable or
greater responsibility as the Board of Directors of the Company may determine)
and shall perform, faithfully and diligently, the services and functions
relating to such office or otherwise reasonably incident to such office as may
be designated from time to time by the Board of Directors of the Company;
provided that all such services and functions shall be reasonable and within the
Executive's area of expertise; and provided further that the Executive shall be
physically capable of performing the essential requirements of the job with or
without reasonable accommodation.

            3.3. Place of Employment. During the term of this Agreement, the

principal executive offices. During the term of this Agreement, the Company will
provide the Executive with a private office, an executive secretary and other
customary staff support services, all as are commensurate with the services and
functions to be performed by him hereunder.

                    (g) The Executive shall be entitled to such vacation,
holidays and other paid or unpaid leaves of absence as are consistent with the
Company's normal policies or as are otherwise approved by the Company's Board of
Directors (or the appropriate committee thereof).

         5. Term. The term of this Agreement shall be for one year and shall be
automatically extended each day, from the effective date hereof.

         6. Termination and Resignation. The Company shall have the right to
terminate the Executive's employment hereunder at any time and for any reason,
and upon any such termination the Executive shall be entitled to receive from
the Company prompt payment of the amount determined pursuant to the applicable
subparagraph of Paragraph 7 below. The Executive shall have the right to
terminate his employment hereunder at any time by resignation, and he shall
thereupon be entitled to receive from the Company prompt payment of the amount
determined pursuant to the applicable subparagraph of Paragraph 7 below.

          7. Payments Upon Termination and Resignation.

             7.1. Pro Rata Payment. In the event of the following:

         (i) the Company terminates the Executive's employment for Cause (as
         defined below),

         (ii) the Executive dies or becomes disabled (being the inability of the
         Executive to perform the essential requirements of the job with or
         without reasonable accommodation),

         (iii) the Executive resigns prior to the occurrence of a Change in
         Control (as defined below) of the Company at a time when there is no
         uncured breach by the Company of any term of this Agreement, or

         (iv) the Executive resigns after the occurrence of a Change in Control
         for any reason other than for Good Reason (as defined below);

then in each case the Executive shall be entitled to receive only his Base
Salary on a pro rata basis to the date of termination or resignation.

             7.2. Base Salary Payment. If prior to the occurrence of a Change in
Control (i) the Company terminates the Executive's employment for any reason
other than for Cause or the Executive's death or disability or (ii) the
Executive resigns because of the breach by the Company of any term of this

Salary.







                                      -3-
<PAGE>   4



                  7.3. Multiple Base Salary Payment. If after the occurrence of
a Change in Control of the Company, (a) the Company terminates the Executive's
employment hereunder for any reason other than for Cause, or (b) the Executive
voluntarily resigns his employment hereunder for Good Reason within one year (as
defined below) of the Change in Control, then in each case the Company will pay
to the Executive a lump sum termination payment equal to 2.99 times the sum of
his Base Salary and his Target Bonus (as defined below) (collectively, the "Lump
Sum Payment"), subject to adjustment as provided in Paragraph 9 below.

                  7.4. Certain Definitions.

                       (a) "Target Bonus" shall mean the target bonus for
Executive specified under the Company's Bonus Plan (as defined in Paragraph
4.2(a)) for the year in which a Change in Control of the Company occurs.

                       (b) Termination by the Company of the Executive's
employment for "Cause" shall mean termination upon the willful misappropriation
of funds or properties of the Company or the willful contravention of the
standards referred to in the last sentence of Paragraph 10 below. For purposes
of this definition, no act, or failure to act, on the Executive's part shall be
considered "willful" unless done, or omitted to be done, by the Executive not in
good faith and without reasonable belief that the Executive's action or omission
was in the best interest of the Company. Notwithstanding the foregoing, the
Executive shall not be deemed to have been terminated for Cause unless and until
there shall have been delivered to the Executive a copy of a resolution duly
adopted by the affirmative vote of not less than three-quarters of the entire
membership of the Board of Directors of the Company at a meeting of the Board
duly called and held (after reasonable notice to the Executive and an
opportunity for the Executive, together with his counsel, to be heard before the
Board) finding that in the good faith opinion of the Board the Executive was
guilty of the conduct set forth above and specifying the particulars thereof in
detail.

                       (c) A "Change in Control" shall be conclusively deemed to
have occurred if (and only if) any of the following shall have taken place: (i)
a change in control is reported by the Company in response to either Item 6(e)
of Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act
of 1934, as amended ("Exchange Act"), or Item 1 of Form 8-K promulgated under
the Exchange Act, or any similar reporting requirement hereafter promulgated by
the Securities and Exchange Commission; (ii) any person, entity or group (as
such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than
any employee benefit plan sponsored by the Company, is or becomes the beneficial
owner (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly,
of securities of the Company representing forty percent or more of the combined
voting power of the Company's then outstanding securities (as determined under
paragraph (d) of Rule 13d-3 promulgated under the Exchange Act, in the case of
rights to acquire common stock); or (iii) following the election or removal of
directors, a majority of the Board consists of individuals who were not members
of the Board two years before such election or removal, unless the election of
each 









                                      -4-
<PAGE>   5




director who was not a director at the beginning of such two-year period
has been approved in advance by directors representing at least a majority of
the directors then in office who were directors at the beginning of the two-year
period.

                       (d) "Good Reason" shall mean, in any case only if an
action or event described in this Paragraph 7.4(d) is not remedied by the
Company promptly after it receives notice thereof from Executive,

                  (i) the assignment to the Executive of any duties
                  substantially inconsistent with the Executive's position
                  (including offices, titles and reporting requirements),
                  authority, duties or responsibilities as contemplated by
                  Paragraph 3.2 hereof;

                  (ii) the failure of the Company to comply with any of the
                  provisions of Section 4.2 hereof; or

                  (iii) the Company's requiring the Executive to be based at any
                  office or location other than as provided in Paragraph 3.3
                  hereof .

         8. Acceleration of Options. Contemporaneously with the occurrence of a
Change in Control of the Company, the Board of Directors of the Company (or the
appropriate committee thereof) will accelerate all outstanding options
previously granted to the Executive under any then existing Company stock
option, stock appreciation or other employee incentive plan that are not
otherwise exercisable by the Executive at the time the Change in Control of the
Company occurs.

         9. Certain Additional Payments by the Company.

            (a) Anything in this Agreement to the contrary notwithstanding, in
the event it shall be determined that any payment or distribution by the Company
or any of its affiliates to or for the benefit of Executive, whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise (any such payments or distributions being individually referred to
herein as a "Payment," and any two or more of such payments or distributions
being referred to herein as "Payments"), would be subject to the excise tax
imposed by Section 4999 of the Internal Revenue Code of 1986, as amended
("Code") (such excise tax, together with any interest thereon, any penalties,
additions to tax, or additional amounts with respect to such excise tax, and any
interest in respect of such penalties, additions to tax or additional amounts,
being collectively referred herein to as the "Excise Tax"), then Executive shall
be entitled to receive and the Company shall make an additional payment or
payments (individually referred to herein as a "Gross-Up Payment," and any two
or more of such additional payments being referred to herein as "Gross-Up
Payments") in an amount such that after payment by Executive of all taxes (as
defined in Paragraph 9(k) imposed upon the Gross-Up Payment, Executive retains
an amount of such Gross-Up Payment equal to the Excise Tax imposed upon the
Payments.









                                      -5-
<PAGE>   6

                  (b) Subject to the provisions of Paragraph 9(c) through (i),
any determination (individually, a "Determination") required to be made under
Paragraphs 9(a) or 9(b), including whether a Gross-Up Payment is required and
the amount of such Gross-Up Payment, shall initially be made, at the Company's
expense, by nationally recognized tax counsel mutually acceptable to the Company
and Executive ("Tax Counsel"). Tax Counsel shall provide detailed supporting
legal authorities, calculations, and documentation both to the Company and
Executive within 15 business days of the termination of Executive's employment,
if applicable, or such other time or times as is reasonably requested by the
Company or Executive. If Tax Counsel makes the initial Determination that no
Excise Tax is payable by Executive with respect to a Payment or Payments, it
shall furnish Executive with an opinion that no Excise Tax will be imposed with
respect to any such Payment or Payments. Executive shall have the right to
dispute any Determination (a "Dispute") within 15 business days after delivery
of Tax Counsel's opinion with respect to such Determination. The Gross-Up
Payment, if any, as determined pursuant to such Determination shall, at the
Company's expense, be paid by the Company to Executive within five business days
of Executive's receipt of such Determination. The existence of a Dispute shall
not in any way affect Executive's right to receive the Gross-Up Payment in
accordance with such Determination. If there is no Dispute, such Determination
shall be binding, final and conclusive upon the Company and Executive, subject
in all respects, however, to the provisions of Paragraph 9(c) through (i) below.
As a result of the uncertainty in the application of Sections 4999 and 280G of
the Code, it is possible that Gross-Up Payments (or portions thereof) which will
not have been made by the Company should have been made ("Underpayment"), and if
upon any reasonable written request from Executive or the Company to Tax
Counsel, or upon Tax Counsel's own initiative, Tax Counsel, at the Company's
expense, thereafter determines that Executive is required to make a payment of
any Excise Tax or any additional Excise Tax, as the case may be, Tax Counsel
shall, at the Company's expense, determine the amount of the Underpayment that
has occurred and any such Underpayment shall be promptly paid by the Company to
Executive.

            (c) The Company shall defend, hold harmless, and indemnify Executive
on a fully grossed-up after tax basis from and against any and all claims,
losses, liabilities, obligations, damages, impositions, assessments, demands,
judgments, settlements, costs and expenses (including reasonable attorneys',
accountants', and experts' fees and expenses) with respect to any tax liability
of Executive resulting from any Final Determination (as defined in Paragraph
9(j)) that any Payment is subject to the Excise Tax.

            (d) If a party hereto receives any written or oral communication
with respect to any question, adjustment, assessment or pending or threatened
audit, examination, investigation or administrative, court or other proceeding
which, if pursued successfully, could result in or give rise to a claim by
Executive against the Company under this Paragraph 9(d) ("Claim"), including,
but not limited to, a claim for indemnification of Executive by the Company
under Paragraph 9(c), then such party shall promptly notify the other party
hereto in writing of such Claim ("Tax Claim Notice").






                                      -6-
<PAGE>   7


                  (e) If a Claim is asserted against Executive ("Executive
Claim"), Executive shall take or cause to be taken such action in connection
with contesting such Executive Claim as the Company shall reasonably request in
writing from time to time, including the retention of counsel and experts as are
reasonably designated by the Company (it being understood and agreed by the
parties hereto that the terms of any such retention shall expressly provide that
the Company shall be solely responsible for the payment of any and all fees and
disbursements of such counsel and any experts) and the execution of powers of
attorney, provided that:

                           (i) within 30 calendar days after the Company
         receives or delivers, as the case may be, the Tax Claim Notice relating
         to such Executive Claim (or such earlier date that any payment of the
         taxes claimed is due from Executive, but in no event sooner than five
         calendar days after the Company receives or delivers such Tax Claim
         Notice), the Company shall have notified Executive in writing
         ("Election Notice") that the Company does not dispute its obligations
         (including, but not limited to, its indemnity obligations) under this
         Agreement and that the Company elects to contest, and to control the
         defense or prosecution of, such Executive Claim at the Company's sole
         risk and sole cost and expense; and

                           (ii) the Company shall have advanced to Executive on
         an interest-free basis, the total amount of the tax claimed in order
         for Executive, at the Company's request, to pay or cause to be paid the
         tax claimed, file a claim for refund of such tax and, subject to the
         provisions of the last sentence of Paragraph 9(g), sue for a refund of
         such tax if such claim for refund is disallowed by the appropriate
         taxing authority (it being understood and agreed by the parties hereto
         that the Company shall only be entitled to sue for a refund and the
         Company shall not be entitled to initiate any proceeding in, for
         example, United States Tax Court) and shall indemnify and hold
         Executive harmless, on a fully grossed-up after tax basis, from any tax
         imposed with respect to such advance or with respect to any imputed
         income with respect to such advance; and

                           (iii) the Company shall reimburse Executive for any
         and all costs and expenses resulting from any such request by the
         Company and shall indemnify and hold Executive harmless, on fully
         grossed-up after-tax basis, from any tax imposed as a result of such
         reimbursement.

                  (f) Subject to the provisions of Paragraph 9(e), hereof, the
Company shall have the right to defend or prosecute, at the sole cost, expense
and risk of the Company, such Executive Claim by all appropriate proceedings,
which proceedings shall be defended or prosecuted diligently by the Company to a
Final Determination; provided, however, that (i) the Company shall not, without
Executive's prior written consent, enter into any compromise or settlement of
such Executive Claim that would adversely affect Executive, (ii) any request
from the Company to Executive regarding any extension of the statute of
limitations relating to assessment, payment, or collection of taxes for the










                                      -7-
<PAGE>   8


taxable year of Executive with respect to which the contested issues involved
in, and amount of, the Executive Claim relate is limited solely to such
contested issues and amount, and (iii) the Company's control of any contest or
proceeding shall be limited to issues with respect to the Executive Claim and
Executive shall be entitled to settle or contest, in his sole and absolute
discretion, any other issue raised by the Internal Revenue Service or any other
taxing authority. So long as the Company is diligently defending or prosecuting
such Executive Claim, Executive shall provide or cause to be provided to the
Company any information reasonably requested by the Company that relates to such
Executive Claim, and shall otherwise cooperate with the Company and its
representatives in good faith in order to contest effectively such Executive
Claim. The Company shall keep Executive informed of all developments and events
relating to any such Executive Claim (including, without limitation, providing
to Executive copies of all written materials pertaining to any such Executive
Claim), and Executive or his authorized representatives shall be entitled, at
Executive's expense, to participate in all conferences, meetings and proceedings
relating to any such Executive Claim.

                  (g) If, after actual receipt by Executive of an amount of a
tax claimed (pursuant to an Executive Claim) that has been advanced by the
Company pursuant to Paragraph 9(e)(ii), hereof, the extent of the liability of
the Company hereunder with respect to such tax claimed has been established by a
Final Determination, Executive shall promptly pay or cause to be paid to the
Company any refund actually received by, or actually credited to, Executive with
respect to such tax (together with any interest paid or credited thereon by the
taxing authority and any recovery of legal fees from such taxing authority
related thereto), except to the extent that any amounts are then due and payable
by the Company to Executive, whether under the provisions of this Agreement or
otherwise. If, after the receipt by Executive of an amount advanced by the
Company pursuant to Paragraph 9(e)(ii), a determination is made by the Internal
Revenue Service or other appropriate taxing authority that Executive shall not
be entitled to any refund with respect to such tax claimed and the Company does
not notify Executive in writing of its intent to contest such denial of refund
prior to the expiration of thirty days after such determination, then such
advance shall be forgiven and shall not be required to be repaid and the amount
of such advance shall offset, to the extent thereof, the amount of any Gross-Up
Payments and other payments required to be paid hereunder.

                  (h) With respect to any Executive Claim, if the Company fails
to deliver an Election Notice to Executive within the period provided in
Paragraph 9(e)(i), hereof or, after delivery of such Election Notice, the
Company fails to comply with the provisions of Paragraph 9(e)(ii), and (iii) and
(f) hereof, then Executive shall at any time thereafter have the right (but not
the obligation), at his election and in his sole and absolute discretion, to
defend or prosecute, at the sole cost, expense and risk of the Company, such
Executive Claim. Executive shall have full control of such defense or
prosecution and such proceedings, including any settlement or compromise
thereof. If requested by Executive, the Company shall cooperate, and shall cause
its affiliates to cooperate, in good faith with Executive and his authorized
representatives in order to contest effectively such Executive Claim. The
Company may attend, but not participate in or control, any defense, prosecution,
settlement or compromise of any Executive Claim controlled by Executive pursuant
to this Paragraph 9(h) and shall 







                                      -8-
<PAGE>   9


bear its own costs and expenses with respect thereto. In the case of any
Executive Claim that is defended or prosecuted by Executive, Executive shall,
from time to time, be entitled to current payment, on a fully grossed-up after
tax basis, from the Company with respect to costs and expenses incurred by
Executive in connection with such defense or prosecution.

                  (i) In the case of any Executive Claim that is defended or
prosecuted to a Final Determination pursuant to the terms of this Paragraph
9(i), the Company shall pay, on a fully grossed-up after tax basis, to Executive
in immediately available funds the full amount of any taxes arising or resulting
from or incurred in connection with such Executive Claim that have not
theretofore been paid by the Company to Executive, together with the costs and
expenses, on a fully grossed-up after tax basis, incurred in connection
therewith that have not theretofore been paid by the Company to Executive,
within ten calendar days after such Final Determination. In the case of any
Executive Claim not covered by the preceding sentence, the Company shall pay, on
a fully grossed-up after tax basis, to Executive in immediately available funds
the full amount of any taxes arising or resulting from or incurred in connection
with such Executive Claim at least ten calendar days before the date payment of
such taxes is due from Executive, except where payment of such taxes is sooner
required under the provisions of this Paragraph 9(i), in which case payment of
such taxes (and payment, on a fully grossed-up after tax basis, of any costs and
expenses required to be paid under this Paragraph 9(i) shall be made within the
time and in the manner otherwise provided in this Paragraph 9(i).

                  (j) For purposes of this Agreement, the term "Final
Determination" shall mean (A) a decision, judgment, decree or other order by a
court or other tribunal with appropriate jurisdiction, which has become final
and non-appealable; (B) a final and binding settlement or compromise with an
administrative agency with appropriate jurisdiction, including, but not limited
to, a closing agreement under Section 7121 of the Code; (C) any disallowance of
a claim for refund or credit in respect to an overpayment of tax unless a suit
is filed on a timely basis; or (D) any final disposition by reason of the
expiration of all applicable statutes of limitations.

                  (k) For purposes of this Agreement, the terms "tax" and
"taxes" mean any and all taxes of any kind whatsoever (including, but not
limited to, any and all Excise Taxes, income taxes, and employment taxes),
together with any interest thereon, any penalties, additions to tax, or
additional amounts with respect to such taxes and any interest in respect of
such penalties, additions to tax, or additional amounts.

                  (l) For purposes of this Agreement, the terms "affiliate" and
"affiliates" mean, when used with respect to any entity, individual, or other
person, any other entity, individual, or other person which, directly or
indirectly, through one or more intermediaries controls, or is controlled by, or
is under common control with such entity, individual or person. The term
"control" and derivations thereof when used in the immediately preceding
sentence means the ownership, directly or indirectly, of 50% or more of the
voting securities of an entity or other person or possessing the 







                                      -9-
<PAGE>   10



power to direct or cause the direction of the management and policies of such
entity or other person, whether through the ownership of voting securities, by
contract or otherwise.

         10. Preservation of Business; Fiduciary Responsibility. The Executive
shall use his best efforts to preserve the business and organization of the
Company and the Company's consolidated subsidiaries (collectively, the
"Consolidated Company"), to keep available to the Consolidated Company the
services of present employees and to preserve the business relations of the
Consolidated Company with suppliers, distributors, customers and others. The
Executive shall not commit any act, or in any way assist others to commit any
act, which would injure the Consolidated Company. So long as the Executive is
employed by the Company, the Executive shall observe and fulfill proper
standards of fiduciary responsibility attendant upon his service and office and
shall comply with the terms of the Company's Statement of Policy Concerning
Corporate Ethics and Conflicts of Interest, as may be amended from time to time.

         11. Competitive Activities.

             11.1 As an independent covenant, Executive agrees to refrain for
one (1) year after the termination of his employment for any reason, without
written permission from the Company, from becoming involved in any way, within
the boundaries of the United States, in the business of manufacturing or selling
any cement or ready-mix concrete products, or other products or services
competitive at the time of the termination with those sold and furnished by the
Consolidated Company as an employee, director, officer, shareholder, consultant,
partner, proprietor, or in any other capacity, except as a shareholder owning
less than five percent of the shares of a corporation whose shares are publicly
traded.

             11.2 As an independent covenant, Executive agrees to refrain during
his employment by the Company, and in the event of the termination of his
employment for any reason, for one (1) year thereafter, without written
permission from the Company, from diverting, taking, soliciting and/or accepting
on his own behalf or on the behalf of another person, firm, or company, the
business of any customer of the Consolidated Company or any potential customer
of the Consolidated Company whose identity became known to Executive through his
employment by the Company.

             11.3 As an independent covenant, Executive agrees to refrain during
his employment by the Company, and in the event of the termination of his
employment for any reason for a period of one (1) year, thereafter, from
inducing or attempting to influence any employee of the Consolidated Company to
terminate his employment.

             11.4 Executive further agrees that these covenants are made to
protect the legitimate business interests of the Company, including interests in
the Company's "confidential information" as defined in Paragraph 12, and not to
restrict his mobility or to prevent him from 








                                      -10-
<PAGE>   11



utilizing his general technical skills. Executive understands as a part of these
covenants that the Company intends to exercise whatever legal recourse against
him for any breach of this Agreement and in particular for any breach of these
covenants.

                  discontinue processes in whole or in part, to discontinue
                  operations in whole or in part, or to discontinue their
                  performance by employees of the Company.

                  requirements determined by management.

         -        to establish and change work schedules, work shifts and
                  assignments.

         -        to transfer, to promote, or to lay off, terminate or

         -        to make and enforce rules for the maintenance of discipline
                  and safety.

be, nor shall it be, restrictive of, or a waiver of, any of the rights of

         Section 1. When it becomes necessary to reduce the working force,

         (a)      Requirements of the job.

         (b)      Experience, individual skill, efficient service, and physical
                  fitness.

         (c)      Seniority.

         (b) Employees will not be terminated by the Company as the result of
mechanization, automation, change in production methods, the installation of
new or larger equipment, the combining of jobs or the elimination of jobs.

         (c) When an employee is no longer needed on his regular job as a
result of conditions described in paragraph (a) above, the Company may
permanently assign such employee to either an available job opening in the
bargaining unit, irrespective of whether or not such job opening is available
for bidding or to a job on which the incumbent has less plant-wide seniority.
Such placement will be to a job in which the employee is reasonably able to
perform within a thirty (30) day on-the-job training period. The rate of pay
for such employee shall not be less than ninety-five percent (95%) of the job
from which the employee was displaced irrespective of the rate of the job in
which he is placed. The 95% rate protection shall apply for a minimum period of
one (1) year, or a period equal to 1/3 of the employee's seniority up to a
maximum of five (5) years. If an employee on 95% rate protection subsequently
bids off the job in which he was placed by the Company during the foregoing
rate protection period, he shall lose his protected rate.

         (d) The provisions of paragraph (c) of this Article do not apply to
displacement or layoffs resulting from production curtailments, except that
employees laid off and not recalled when production is resumed following
curtailment will be entitled to the same rights as employees affected by the
preceding paragraph (c).

         (e) Should the Company permanently shut down the present facilities
affording employment to the employees comprising the bargaining unit (the
present facilities shall be deemed to have been permanently shut down if all
productive facilities are abandoned even though the shipping facilities
continue to operate) the Company shall mail a notice informing each affected
employee that his employment with the Company has been terminated because of
the permanent shutdown. The notice shall be mailed at least ninety (90) days
prior to the shutdown to the employee's last address on the company's records.
Each employee who is mailed said notice shall have the following options:

         (1) An employee who is not eligible for a normal (excluding 30-year
retirement pension) or late retirement pension may elect to transfer to another
operation of the Company covered by a collective bargaining agreement with the
Union in accordance with Paragraph (f) or Paragraph (g). Any transfer pursuant
to Paragraph (f) or Paragraph (g) will occur not later than three years after
the last day the employee worked. An employee awaiting transfer shall be placed
on layoff and shall receive SUB layoff or reduced layoff benefits provided the
eligibility and other requirements of the SUB Plan are met.* An employee may
void his election to transfer at any time during the three-year period. If the
employee is eligible for an immediate pension at the time he voids his election
to transfer, he shall retire, effective the date he voids his election, under
the Pension Plan in effect at the time of the permanent shutdown. An employee
may also void his election in order to apply for SUB termination benefits.*

         (2)    An employee who is eligible for an immediate pension at the
                date of the permanent shutdown shall retire as of the effective
                date of the permanent shutdown, except:



                                       7
<PAGE>   8



                a.    An employee whose combined age and years of service equal
                      62 or more but less than 65 may elect layoff until his
                      combined age and years of service equal 65 at which time
                      the employee shall retire and receive a permanent
                      shutdown pension. The Pension Plan in effect at the time
                      of the permanent shutdown shall determine the retirement
                      benefits payable to the employee. An employee who elects
                      layoff under these conditions shall receive SUB layoff or
                      reduced layoff benefits provided the eligibility and
                      other requirements of the SUB Plan are met.*

                b.    An employee who is eligible for an immediate pension
                      other than a normal or late retirement pension and who
                      elects to transfer to another operation of the Company
                      shall not retire unless the transfer is not accomplished.

                c.    An employee shall not be required to retire under a
                      disability retirement pension earlier than he would
                      otherwise be required to retire if the Company had not
                      permanently shut down the facilities.

                d.    An employee who retires under the Pension Plan may also
                      be entitled to receive SUB Termination Benefits in
                      accordance with the terms of the SUB Plan.*

         (3)    The employee may elect SUB Termination Benefits in accordance
                with the terms of the SUB Plan at any time within one year
                after notice of termination has been mailed to him.

                An employee other than an employee who is eligible for an
                immediate pension may elect layoff prior to submitting his
                application for SUB Termination Benefits and shall receive SUB
                layoff or reduced layoff benefits provided the eligibility and
                other requirements of the SUB Plan are met.*

         (4)    If the facilities which have been permanently shutdown are
                reopened by the Company within three years of the date of the
                permanent shutdown, an employee who has retired under the
                Pension Plan shall be eligible for recall in accordance with
                his seniority status at the time of the permanent shutdown. An
                employee who has elected SUB Termination benefits shall also be
                eligible for recall in accordance with his seniority status at
                the time of the permanent shutdown. Any pensioner who has
                received SUB Termination Benefits* and accepts recall and any
                former employee who has received SUB Termination Benefits* and
                accepts recall shall repay said Termination Benefits to the SUB
                Trust Fund or the Company, whichever was the source of the
                Termination Benefits, in accordance with the SUB Plan
                Agreement.* Any employee who accepts recall shall have his
                previously accumulated seniority rights, pension, SUB,
                insurance and vacation credits as of the last day the employee
                worked or at the date of the permanent shutdown, whichever
                occurs later, reinstated on the date he returns to work.



                                       8
<PAGE>   9

         (5)    An employee who is not eligible for an immediate pension may
                elect layoff and shall receive SUB layoff or reduced layoff
                benefits provided the eligibility and other requirements of the
                SUB Plan are met.* The employment rights of any employee on
                layoff shall terminate three years after the last day the
                employee worked and the employee's seniority shall be broken.

         (6)    An employee's participation in the group insurance program
                shall terminate effective the day following the last day the
                employee worked and pending claims shall be processed in
                accordance with the terms of the existing group insurance
                program. No employee shall be eligible for holiday pay or
                vacation pay other than vacation pay due after the last day the
                employee worked or the date of the permanent shutdown,
                whichever occurs later. No employee shall accumulate credited
                service under the Pension Plan after the last day the employee
                worked or the date of the permanent shutdown, whichever occurs
                later.

         *The Supplemental Unemployment Benefit (SUB) Plan was terminated
         effective July 1. 1990. The funds currently in the Trust Fund of this
         plan will be used to pay Layoff Benefits, Workmen's Compensation
         Supplemental Benefits and/or Termination Benefits until such funds are
         exhausted. At that time, Layoff Benefits will be provided by Article
         XX, Section 1 (d) and Termination Benefits provided by Article XVII,
         Section 1 of this Agreement.

         (f) In the event the Company constructs a new plant that will affect
the employment status of employees in the Company's plant or plants comprising
this bargaining unit, such employees shall be given an opportunity to make
application for employment in the new plant before it starts operation, and
such employees shall be given preferential employment rights for the highest
rated job the employee is capable of performing. Such an employee shall
transfer with him all of his previously accumulated pension, SUB, insurance and
vacation credits. His seniority rights at the former plant shall terminate upon
his establishment of seniority rights in the new plant.

         (g) When an employee has been laid off or displaced because of
permanent changes in the working force or because of a plant closing, he may
make written application within fifteen (15) days of layoff or displacement for
employment in another plant of the Company and he shall be given preferential
employment rights of job openings at such other plant, providing such employee
is capable of performing the job that may be available at such other plant of
the Company.

         Any employee so transferring from one plant to another of the Company
shall retain his previously accumulated pension,SUB, insurance and vacation
credits. His seniority rights at the former plant shall terminate upon his
establishment of seniority rights in the plant to which he transferred.

         (h) Employees transferring from one plant to another as provided in
this Article will receive a moving expense allowance. The Company will
reimburse each employee for actual moving expenses incurred to move furniture
and other household goods up to a maximum of $1,500 per employee.

paying more per hour than the plant base rate, shall be posted promptly and
remain posted for five (5) days to allow any employee to make application in
writing for such jobs. The applications shall be considered in the order of the
seniority of the applicants. If the senior applicant is not selected, the
Company, in consultation with the Union Committee, shall give consideration to
the applications and choose an applicant on the basis of seniority, ability,
experience, and qualifications to fill the requirements of the job. If no
applications are received with necessary qualifications, Management reserves
the right to hire a qualified person.

         (b) An employee awarded a job in conjunction with the job bidding
procedures shall be placed on the new job consistent with reasonable
replacement criteria. After being placed on the new job, the employee will be
given a period not to exceed thirty (30) working days within which to qualify
for the job. During the qualifying period, he will receive no less than the
rate of pay for the job he held permanently immediately prior to such
qualifying period. At the conclusion of the qualifying period, and if the
employee is found to be qualified by the Company, the employee will be paid the
rate of pay for the new job. If the employee fails to qualify within the thirty
(30) working day qualifying period, he shall be returned to his former job
without prejudice.

         (c) Subject to the foregoing, when transfers into a Classification
result in the classification operating 50% of the time (during a normal 8 hour
work shift) in any seventy-five (75) day period, the classification will be
posted.

         Section 3. The Company will furnish the Local Lodge with a copy of the
notice of job vacancy at the time it is posted and copies of the applications
received for such job after the job is awarded to the successful applicant.

         Section 4. It is agreed that experience gained through temporary
upgrading will not be used in filling permanent vacancies except that
experience gained through temporary upgrading may be used in qualifying the
most senior bidder in filling permanent vacancies.

         Section 5. An employee who has successfully bid on, been awarded a new
job, and has completed his probationary period in the new job shall not be
eligible to bid on another new job for a period of six (6) months from the date
that he was awarded the job. In no event shall an employee be awarded more than
two (2) jobs in any calendar year. No temporary or probationary employee shall
be eligible to bid on any job vacancy. Downward bidding will be permitted one
time every twelve months when a vacancy exists. A person cannot bid on any
other job for one year after bidding down.

regular hours of labor shall consist of eight (8) hours within a consecutive
nine (9) hour period in one day and forty (40) hours in one week.

         (b) Work schedules for each work week will be posted on Thursday of
the previous week prior to the end of the first shift. If an employee's work
schedule is changed without at least seventy-two (72) hours notice prior to the
beginning of the new shift, the employee shall be compensated by multiplying
the regular straight-time hourly rate by one-half (0.5) for the first eight (8)
hours worked in the new schedule and the premium shall be paid in addition to
whatever compensation the employee is entitled to receive. Notice required for
shift change shall be twenty-four (24) hours when the kiln goes down (when the
fire goes out in the kiln) in the maintenance, electrical and service
departments. If the work schedule is otherwise changed after Thursday,
employees will be paid as provided in this agreement.

         (c) It is agreed that all employees will be scheduled to work five (5)
consecutive days in a work week, insofar as practicable and consistent with
efficient operation.

         Section 2.

         (a) For the purpose of determining overtime, eight (8) hours shall
constitute a day's work, and forty (40) hours a week's work. Time and one-half
shall be paid for all overtime in excess of eight (8) hours in any one day or
for all overtime in excess of forty (40) hours in any one week, provided,
however, that hours paid for at the overtime rate on the daily basis will not
be included or duplicated in figuring the weekly hours on which overtime is
paid. Employees who are called upon to work in excess of their scheduled hours
in any one day shall not be laid off during their regular scheduled working
time to equalize this overtime.

         (b) There will be no pyramiding or duplication of overtime or
premiums. Time worked by an employee shall be paid on one basis only. If two or
more premium rates or overtime rates apply to the same hours, the one rate

                Double time                                   Double time
</TABLE>

         Section 4. In the event an employee works more than sixteen (16) hours
in the work day, he shall be paid for all hours worked in excess of such
sixteen (16) hours at double his regular straight-time hourly rate.

         After an employee has been engaged in work for sixteen (16)
consecutive hours, he shall be paid for all consecutive hours worked
immediately succeeding and in excess of such sixteen (16) hours at double his
regular straight-time hourly rate.

         If an employee is being paid the rate of double time under the
foregoing paragraphs, his rate of pay shall not be reduced when his work
continues into or overlaps his regular shift. However, the Company may exercise
either of the following options:

         (a) The Company may instruct the employee to continue to the end of
the shift at the double time rate, or,

         (b) The Company may send the employee home at any time during the
shift, provided the remainder of the shift is paid for at straight time. Such
employee cannot be called back to work until he has been off duty for eight (8)
consecutive hours.

         In no event shall the first two provisions of this section be applied
to the same hours of work. The provision which creates the highest earnings
shall be applied.

         Section 5. When an employee is scheduled and reports for work and is
not permitted to start work, he shall receive four (4) hours pay at his regular
straight-time hourly rate. In the event an employee commences work on his
scheduled shift and work ceases during his shift for any reason and there is no
other available work for him, he shall be paid a minimum of eight (8) hours at
his regular straight-time hourly rate.

         Section 6. An employee who has left the plant and who is called in by
the Company to work outside his regular schedule shall be paid at time and
one-half (1.5) for all hours worked. If the job for which he was called to
perform does not provide at least four (4) hours work, he may be assigned other
work, related to an emergency or production difficulty, for which he is
qualified. If no such assignment of work is made, he shall be paid a minimum of
four (4) hours. If such assignment is made and the employee refuses it, he
shall be paid only for the time actually worked.


                                      12
<PAGE>   13

         Section 7. When an employee is required to work in excess of his
scheduled hours in any one day, he shall be paid a minimum of one-half (.50)
hour at the applicable overtime rate; provided, however, that at least eight
(8) minutes of work is performed. For each additional one-half (.50) hour
segment during which at least eight (8) minutes of work is performed, the
employee shall be paid the applicable overtime rate for that segment. An
employee will be required to work the full one-half hour if requested. If an
employee declines to work the full one-half hour as requested, the employee
will be paid for time worked.

         Section 8. Any employee required to work any part of his scheduled
lunch period by direction of a Foreman, shall receive time and one-half for the
scheduled 1/2 hour lunch period and be allowed necessary time later to eat his
lunch without loss of pay.

         Section 9. Overtime shall be equally distributed among employees
within a classification in each department, insofar as it is practicable to do
so over the period of a calendar year. Overtime records will be posted in each
department and updated weekly.

         Section 10. It is not the desire or intent of the Company to have
Company personnel excluded from the bargaining unit routinely perform
bargaining unit work. The Company and the Union recognize that in certain
situations it may be necessary for Company personnel to perform work regularly
assigned to bargaining unit employees in order to maintain and/or safeguard the
operation of the facility. The Company supervisory personnel will determine the
necessity for the performance of such work. The Company is willing to meet with
the Union at reasonable times to discuss the reasons for the performance of
such work, if requested.

*Such work shall include:

         (a)      Work involving corrective action which must be performed
                  expeditiously or the continuity of operation would be
                  impaired.

         (b)      Instruction or training of employees.

         (c)      Inspection or testing of equipment.

         (d)      Work of an emergency nature.

         (e)      Development work for new processes and/or procedures.

         (f)      Demonstration of equipment.

         (g)      Relief of regular employees for lunch or break periods.

         Section 11. Any regular employee (as distinguished from a probationary
employee) required to perform jury duty on a day he is scheduled to work, shall
be excused from work on that day. The Company shall pay the employee the
difference between the amount received for such jury duty and eight hours at
his regular rate of pay plus shift differential if involved.



                                      13
<PAGE>   14



         The day or days paid for such jury service shall be counted as eight
(8) hours worked for the purpose of computing weekly overtime.

         Section 12.

         (a) Employees, upon the notification of the death of his or her
father, mother, spouse, son, daughter, brother, sister, stepfather, stepmother,
stepson, stepdaughter, half brother, half sister, mother-in-law, father-in-law,
brother-in-law, sister-in-law, grandparent, spouse's grandparent, and
grandchild, shall be granted his or her next three (3) scheduled working days
off with pay (four (4) days off with pay if the employee is required to travel
beyond a radius of 500 miles), which will be either the day of the funeral or
days immediately preceding or following the day of the funeral. Payment by the
Company for such time lost shall be on the basis of eight (8) hours per day at
the employee's regular straight-time hourly rate, including shift differential.

         (b) The above clause shall not apply to employees on a layoff except
that when an employee is notified to return to work effective on or before the
date of the funeral, he shall be granted full funeral leave with pay.

         (c) As used herein, brother-in-law is defined to mean:

             (1)      the brother of one's husband or wife,

             (2)      the husband of one's sister,

             (3)      the husband of the sister of one's spouse.

             The sister-in-law is defined to mean:

             (1)      the sister of one's husband or wife,

             (2)      the wife of one's brother,

             (3)      the wife of the brother of one's spouse.

         Section 13. Every reasonable effort will be made by the Employer to
avoid requesting any employee to work overtime and employees will not be
penalized for refusing to work overtime if a reasonable excuse is given to the
supervisor. Whenever an employee is on layoff due to lack of work or because of
curtailment of operations, no overtime work will be scheduled on any work which
the laid-off employee is capable of doing and is able to perform, except in
cases of emergency callouts for emergency repair or unscheduled absences of
other employees. The foregoing to the contrary notwithstanding, a laid-off
employee will not be called back to work unless there is at least thirty-two
(32) hours' work within the payroll week for such employee.

         Section 14.

         (a) Active employees with one year seniority and who are in the
Reserve of any branch of the military service, including the National Guard,
who are required to attend a summer encampment as part of their Reserve
obligation shall receive from the Company the difference between the amount of
pay received for such summer encampment and his regular straight-time hourly
rate of pay for up to a maximum of two (2) weeks per calendar year.



                                      14
<PAGE>   15



         (b) If a National Guard or Reserve member is required to attend a
National Guard or Reserve Meeting on one of his regular scheduled work shifts,
the Company will try to reschedule the employee as long as the employee gives
the Company sufficient notice (before the next schedule is posted) and there is
no penalty to the Company.

         Section 15.

         (a) Any employee who becomes incapacitated and, on the basis of
competent medical opinion, cannot perform the duties of his regular job, may
exercise his plant seniority through the bumping procedure to move to another
position within the bargaining unit at the plant for which he could qualify
within a reasonable period of time, but not to exceed ninety (90) days. This in
no way attests the bidding rights of the employee. (The 95% rate protection is
not applicable to bumping under this provision.)

         (b) Any employee who is displaced by an incapacitated employee
pursuant to paragraph (a) of this Section may exercise his plant seniority to
bump into another position within the bargaining unit at the plant for which he
is qualified in the same manner as provided for in the job bidding procedures.

         Section 16.

         (a) When an employee works more than two (2) hours overtime,
consecutive and in addition to his regularly scheduled shift hours, and every
six (6) hours thereafter, the Company will provide a hot meal or payment in
lieu of the meal in the amount of $7.50.

         (b) When an employee is called out and reports to work more than two
(2) hours prior to the start of his regularly scheduled shift and continues to
work into his scheduled shift or does not receive at least one (1) hour off
between the start of his regularly scheduled shift and the end of the call-out
work (two (2) hours minimum), the Company shall provide a hot meal or payment
in lieu of the meal in the amount of $7.50 and will provide an additional hot
meal, or payment in lieu of the meal, in the amount of $7.50 every six hours
thereafter.

         (c) The above provisions shall not apply if the overtime or call-out
hours worked are scheduled or arranged four (4) or more hours prior to the
start of the employees regularly scheduled shift or if the hours are required
to fill the unscheduled absence of another employee. On non-scheduled days, a
meal will be provided after ten (10) hours of work and every six (6) hours
thereafter.

         (d) There shall be no duplication of lunches or payments under (a) and
(b) above.

                                   ARTICLE IX

                                CHANGE IN RATING

         Section 1. An employee normally performs work in both higher and lower
rated jobs when required. When employees are assigned to temporarily perform
work a higher rated job, they



                                      15
<PAGE>   16



will receive the higher rate of pay for hours worked in such higher rated jobs.
If an employee is temporarily assigned to such job for four (4) or more hours
in the workday, he will receive the higher rate of pay for the entire workday.
If he is scheduled on the weekly work schedule on a higher rated job in another
classification, he shall receive the higher rate of pay for the entire workday.
An employee's pay rate will not be reduced when the temporarily assigned to
work in a lower rated job. This provision shall not apply to employees
displaced during periods of temporary production curtailments.

         Section 2. During periods of plant shutdown when employees are needed
for maintenance, repairs, or work on plant alterations, the rate paid to
employees who are retained for work during the first forty-five (45) days of
the shutdown shall not be less than the regular straight-time hourly rate
normally paid when the plant is on production. After forty-five (45) days, and
subject to paragraphs (a) and (b) of this Section, the regular straight-time
hourly rate paid for all classes of work shall govern for such employees whose
regular straight-time hourly rates are higher or lower.

         A plant shutdown, as referred to herein, is defined as a period during
which none of the clinker burning units are in production.

         During periods of plant shutdowns, employees retained to perform
necessary work shall be selected on the following basis:

         (a) Senior employees, whose regular jobs are not required, shall have
the option of accepting available work for which they are qualified, or
accepting layoff, except that,

         (b) The Company has the right to require that senior employees work
during the shutdown if there are no junior employees with the necessary
qualifications to perform the required work.

         The foregoing in no way alters the procedure which has been followed
in handling of reductions brought about by production curtailment.

         Section 3.

         (a) In the event that an employee is required to clean and/or repair
roofs, scale a quarry face, or work inside a silo, the hours worked shall be
compensated for by multiplying the classified hourly wage rate by one-half
(0.5) for each and every hour worked, and this premium shall be paid in
addition to whatever compensation the employee is otherwise entitled to receive
under any other section of this Agreement. Employees will not be required to
work in coolers and/or other equipment until such equipment has been reasonably
cooled so as not to endanger the employee's safety.

         (b) In the event an employee is required to work inside the raw mix
tanks (raw silos). coal tanks, sand tanks, chalk tanks, hard rock tanks, scale
house (truck loading) tanks, or when spudding out gypsum tanks, or when a
passenger is in the crane cage, or when working with an asbestos suit, the
hours worked shall be compensated for by multiplying the classified hourly wage
rate by one-half (0.5) for each and every hour worked, this premium shall be
paid in addition to whatever compensation the employee is otherwise entitled to
receive under any other section of this Agreement.

(c) When unplugging a choked cyclone (including waste cyclone) from the cone
area (and meal valves), mixing box (if door is open) or going inside the
cyclones and duct work, pay as in 4 (a) (b) is applicable.

                            Christmas Day

         If any of the foregoing holidays fall on Sunday, the following Monday
shall be observed as the holiday. If the Monday involved is also a holiday, the
following Tuesday will be observed as the holiday.

         For the purpose of this Section, a holiday is defined as a twenty-four

immediately preceding or immediately following the holiday except that the
thirty day limitation shall not apply if the employee was temporarily absent
from work because of sickness, accident, or layoff. In any event, the employee
must work at least one day in the calendar year in which the holiday is
granted.


                                      17
<PAGE>   18



         Section 4. If a holiday occurs during an employee's vacation period,
such employee will receive an additional eight (8) hours pay, provided he meets
the following conditions:

         (a) The employee performs his scheduled hours of work on his last
scheduled workday preceding his vacation, and also on his first scheduled
workday following his vacation, except that absence from all or a part of his
scheduled hours on such days shall not disqualify an employee from receiving
holiday pay, if such absence is due to proven personal illness or other proven
unavoidable cause satisfactory to the Plant Manager.

         Section 5.

         (a) Employees reporting for work on holidays will be guaranteed eight
(8) hours pay at two and one-half (2 1/2) times the regular straight-time
hourly rate.

         (b) Callout hours worked outside of an employee's regular holiday
scheduled shift and overtime hours worked on a holiday shall be compensated at
a rate of two (2) times an employee's regular straight-time hourly rate.

         (c) Employees scheduled to work on a holiday but failing to report for
and perform such work shall not be entitled to any holiday pay.

         Section 6. When a holiday falls on a day on which an employee would
otherwise have been scheduled to work, such time paid for but not worked - not
in excess of eight hours - shall be considered as hours worked for the purpose
of computing weekly overtime.

                                   ARTICLE XI

                                     WAGES

         Section 1. The wage scales attached hereto (Appendix A) and made a
part hereof shall be effective for the periods indicated thereon, except in
case of new jobs and job changes made necessary by the installation of new and
different equipment, or changes made necessary in the process of manufacturing.
The Management, at its discretion, may voluntarily increase wages in any class
or to any individual or class without necessitating a change in the wage of any
other individual or class.

         (a) In the event the permanent job content of any job classification
is substantially changed, or a new job created, the Company shall set a rate

Company, on the question of whether the rate bears fair relationship to the
rates of other jobs in the plant based on comparable requirements of skill and
effort.



                                      18

</TABLE>

         (c) Request for pay in lieu of time off must be submitted prior to
March 1 of the year during which the vacation is due.

         (d) Vacation periods shall be in minimum units of one week (five
regular work days) duration.

         Section 3. Vacation pay will be based on a forty (40) hour week at the
rate of the permanently assigned classification on which an employee is working
at the time he takes his vacation. If an employee has held a single higher
rated classification for more than six (6) months during the year preceding his
vacation, he will receive vacation pay computed at the higher rate. Vacation
pay shall include appropriate shift differential for those on fixed shifts.
Employees working on rotating shifts shall be paid an average of the rates for
the rotating shifts involved.

         Section 4. Vacation shall be considered by both parties as a period of
recreation and all eligible employees shall receive the benefit of being absent
from work during such period as may be agreed upon, scheduled, and posted prior
to June 1st of each year. Vacations will, as far as possible, be granted at
times most desirable to employees. Seniority shall be given preference in the
selection of vacation periods but the final right of allotment of vacation
period is exclusively reserved to the Management in order to insure the orderly
operation of the plant.

         Section 5. Vacations will not be cumulative, but so far as practicable
will be granted at times most desired by employees, but the final right of
allotment, including vacation assignment during periods of shutdown and
curtailment, is exclusively reserved to the Company in order to insure the
orderly operation of the plant.

         Where requested vacation periods conflict, preference shall be given
to the employee who is senior in service.

         Section 6. An employee with more than one (1) year of seniority shall,
with respect to earned vacation time subsequent to his last employment
anniversary date, be entitled to credit for such time upon termination for any
reason, prorated on the basis of one-twelfth (1/12) for each one


                                      22

hundred (100) compensated hours; but such probation shall not exceed his
maximum allowable annual vacation.

         Section 7. In case of termination of an employee for any reason, the
Company shall pay him or, in the event of his death, to the beneficiary of Life
Insurance, any vacation due him.

         Section 8. The Company will permit employees to use up to one (1) week
of this vacation on a day-to-day basis for prearranged personal business.
Prearrangement for use of vacation for personal business must provide the
Company with ample time to change work schedules without payment of the change
of schedule penalty.

                              GRIEVANCE PROCEDURE
                             HANDLING OF COMPLAINTS

         Section 1. The purpose of this Article is to provide an orderly method
for adjustments of differences which may arise between the Company and the
Union.

         Section 2.   Grievances shall be processed in the following manner:

         (a) The employee and/or his Committeeman within a five (5) day period
shall first make an effort to arrive at a satisfactory agreement with the
employee's foreman. The foreman shall answer the grievance within two (2) days
(exclusive of Saturday, Sunday and Holidays). If the grievance is not
satisfactorily settled at Step (a), the grievant or Local Committee may process
the grievance to Step (b) provided, however, they do so within thirty (30) days
from the occurrence or the alleged grievance becomes known.

         (b) Failing to arrive at a satisfactory settlement at Step (a), the
grievance may, within thirty (30) days after the occurrence, be reduced to
writing and submitted to the Plant Manager. Such grievance(s) will be discussed
at a meeting to be held monthly, or at any other mutually agreeable time, and
every effort will be made to settle the dispute. The Plant Manager or his
designee shall answer the grievances within five (5) working days of the second
step meeting.

         (c) Any grievance(s) not resolved in accordance with Step (b) above
may be referred by the Union Committee to the Director, Employee Relations or
his designee and a Representative of the International Union. The
Representative of the International Union and the Director - Employee Relations
or his designee and the Union Plant Committee shall meet to discuss such
grievances within thirty (30) days after receipt of the written answer in
Section 2 (b). (The time limits may be extended by mutual agreement between the
parties.)

         The Director - Employee Relations or his designee shall give his
answer(s) in writing within ten (10) working days after the third step meeting.



                                      23
<PAGE>   24

         Section 3. Any grievance which is not resolved in accordance with the
above procedure may be appealed to arbitration upon written notice of either
party to the other within fifteen (15) days exclusive of Saturday, Sunday or
Holidays after receipt of written answer in Section 2(c).

         In the event the parties cannot agree upon an impartial arbitrator
within ten (10) days, the party desiring arbitration may request the Federal
Mediation and Conciliation Service to submit a list from which an arbitrator
shall be chosen.

         The decision of the arbitrator shall be final and binding upon both
parties. It is understood, however, that the impartial arbitrator shall have no
authority to change, add to, or subtract from any of the provisions of this
Agreement.

         (a) It is agreed that no more than four (4) cases will be presented at
one (1) series of hearings.

         (b) It is agreed that any expense incurred in connection with
arbitration shall be paid in equal amounts by the Union and the Company.

         Section 4. In the event an employee is discharged and desires to take
up the matter as a grievance, then this complaint shall be filed in writing
with the Plant Manager within three (3) days after discharge (excluding
Saturday, Sunday, and Holidays), and shall be promptly carried through the
applicable provisions for the handling of grievances, including arbitration, if
necessary. If no complaint is filed within three (3) days, then the Company
will be deemed to have been within its rights in such discharge.

         Section 5. Nothing in the Agreement shall be construed as obligating
the parties to arbitrate any contract negotiations.

         (a) Any grievance not processed within the time limits specified in
this Article shall be forfeited without precedent or prejudice with regard to
future cases.

         Section 6. The Company agrees that so long as this Agreement is in
effect, there shall be no lockouts. The closing down of the facility or any
part thereof or curtailing any operations or routes for business reasons shall
not be construed to be a lockout.

         The Union, its officers, agents, members, and the employees covered by
this Agreement, agree that so long as this Agreement is in effect, there shall
be no strikes, sit-downs, slow-downs, stoppages of work, boycotts, holidays
other than those provided by this Agreement, continuous meetings, concerted
mass sickness or any other acts or denial or services which would interfere
with the Company's operations and it is further agreed that the Union, its
officers, agents, members and the employees covered by this Agreement shall not
encourage, condone, or engage in any sympathy strike nor honor any picket line,
strike, sit-down, slow-down, work stoppage, boycott, labor holiday, continuous
meeting, concerted mass sickness or any other acts or conduct that interfere
with the Company's operations.

         The Union, its officers, agents, members and employees agree that if
any acts, conduct or withholding of services prohibited by this Article occur
or are threatened, they shall take all


                                      24
<PAGE>   25



reasonable and necessary steps to prevent and stop any and all such
interference by persons subject to this Agreement. Such reasonable and
necessary steps shall include, but not be limited to, immediately dispatching a
representative to the scene of the interference; removing or restraining all
local Union officers, stewards, and/or committeemen participating in activities
violating this Article, sending, within eight (8) hours, a telegram to each
employee, demanding, exhorting and requiring each employee to immediately cease
any activities violating this Article, and to return to work and honor the
terms and conditions of this Agreement; and in addition, the Union shall
discipline the employees who participated in activities violating this Article.

         Any employee subject to the terms of this Agreement who violates
Section 6 of this Article will be subject to disciplinary action by the
Company, including discharge.

         There shall be absolutely no interference by the Union, its officers,
agents, employees, or members, to prevent or impede free ingress and/or egress
by any person to and from the Company's property or customer's property or the
free and unhindered use of Company's, customer's or supplier's equipment or
vehicles.

         Section 7. An employee shall have the right to see his Union Steward
(Committeemen) or other available member of the Union Committee to discuss any
matter affecting his rights or privileges. A steward or other officer of the
Local Lodge shall, upon request to his supervisor, be granted relief from his
job for a reasonable period of time to investigate or attempt to settle a
dispute. The steward or other officer of the Local Lodge shall not leave his
job without the consent of his supervisor and such request for relief shall not
be unreasonably denied. Local Lodge Officers and Stewards (Committeemen) off
duty, and representatives of the International Union, shall, upon notice to the
Company, be permitted on the Company's premises to investigate grievances.

         Section 8. Meetings will be conveniently scheduled so as to complete
all business within the normal working day for day employees. Any employee who
is scheduled to work during the hours the meeting is held and who attends the
meeting will be compensated by multiplying his regular classified hourly wage
rate by the hours he attends the meeting. In addition, if this employee attends
the meeting beyond his normal quitting time, he will be compensated for each
additional hour he attends the meeting by multiplying his regular classified
hourly wage rate by one (1) and said additional hour or hours shall not count
toward daily or weekly overtime.

         Section 9. Any member of the Committee who is not scheduled to work
during the hours the meeting is held, who is not scheduled to work the third
shift immediately following the meeting, and who attends the meeting, will be
compensated by multiplying his regular straight-time hourly wage rate by all
hours he attends the meeting. Any hours paid under this paragraph shall not
count toward the calculation of any penalty or premium pay section of this
Agreement including but not limited to daily or weekly overtime. Any employee
who is receiving SUB benefits, sickness and accident benefits, or Workmen's
Compensation benefits for the day of the meeting or who is absent due to
disciplinary layoff shall not receive any compensation under this paragraph.

<PAGE>   26



         Section 10. When a meeting is scheduled at which a representative of
the International Union and a representative of the Company from Cleveland will
attend, any member of the

Committee who is scheduled to work the third shift immediately preceding the
meeting will be excused from working the third shift and will be compensated by
multiplying eight (8) hours at his regular classified hourly wage rate plus
shift differential if the employee has attended the meeting.

         Any member of the Committee who is scheduled to work the second shift
if the employee has attended the meeting for six (6) hours. In the event the
employee is excused from working the second shift, he will be compensated by
multiplying eight (8) hours at his regular classified hourly wage rate plus
shift differential.

         Section 11. Unsatisfactory Performance Reports and/or disciplinary
letters will be removed from the employee's personnel file after twelve (12)
consecutive months and will be destroyed.

         Section 12. When there is to be a discussion between an hourly
employee and a supervisor that is intended to be a disciplinary measure, the
Union will, if requested by the employee, insure that a Committeeman or other
designated employee be present.

         It is not the intent of this Section to expand the total number of
Committeemen as provide in Section 1 of Article III.

                                  ARTICLE XVI

coverages will be reinstated upon returning to work with the Company. Upon
returning to work, such employee will be reinstated on his former job,
providing it is still in existence; if not, he shall be eligible to apply for
any job within the bargaining unit by means of the existing bidding procedure
or by bumping.

                              TERMINATION BENEFIT


         Section 1. The Company will pay benefits in amounts equal to those
provided by Section 2 of Article VII of the SUB Plan upon termination of
employment of an employee who is age sixty-five (65) or older, provided such
employee is not eligible for a pension under the current Pension Plan covering
bargaining unit employees.

         On or after July 1, 1990, an employee with at least one year of
Credited Service (computed as of the date of his application for a Termination
Benefit) shall be eligible for a Termination Benefit in an amount as provided
in Section 2 of this Article. Upon termination of his employment, provided,
however, that if a terminated employee shall not have applied for such benefit
within one year after the Company shall have mailed notice of his termination
to him at his last address as shown on Company records, his right to such
benefit shall stand forfeited. In no event shall a Termination Benefit be paid
upon normal or disability retirement of an employee under the terms of the
Pension Plan for Hourly Employees of the Company.

         But provided further, however, that if a terminated employee shall die
within one year after the Company shall have mailed notice of his termination
to him at his last address as shown on Company records and such employee has
not made application for such benefit prior to his demise, such benefit in the
amount which would have been payable to him in any event shall be paid to the
deceased employee's beneficiary.

         "Termination" as used in Sections 1 and 2 of this Article solely means
ceasing employment from the Company by reason of a layoff commencing on or
after the effective date of this Agreement of two or more years duration (or
lesser duration where loss of seniority is involved) or a termination of
employment from the Company resulting from a permanent shutdown of the plants
department or subdivision thereof, which occurs after the effective date of
this Agreement. The term also includes termination of employment from the
company by reason of disability, where such disability occurs on or after
February 1, 1993, where the employee is age sixty-five (65) or older and the
employee is not eligible for an immediate Pension under the Pension Plan
covering bargaining unit employees.

         Section 2.

         The lump sum Termination Benefit payable on the termination of an
eligible employee who is ineligible for an immediate normal, late, disability
or early retirement benefit under the Pension Plan shall be forty (40) times
the product of the employee's years of Credited Service and his regular
straight-time hourly rate. The lump sum Termination Benefit payable on the
termination of an eligible employee who is eligible for an early retirement
benefit under the Pension Plan shall be twenty (20) times the product of the
employee's years of Credited Service and his regular straight-time hourly rate.

         If the Company reopens facilities which had been permanently shut down
within three years of the date of the permanent shutdown, any pensioner, or
former employee who has been paid termination benefits in accordance with the
collective bargaining agreement and who returns to work, shall be required to
reimburse the Company an amount equal to the termination benefits at a rate not
to exceed $25.00 per calendar week.

                                  CONTRACTORS

Section 1.

(a)    Contracting or subcontracting of work by the Company will not directly
       result in the layoff or other reduction of employees on the seniority
       lists except through attrition of such employees in the respective
       bargaining unit by quits, retirements or discharge for cause. The
       foregoing to the contrary notwithstanding, manpower reduction
       limitations do not apply to contracting arrangements for:

       1.     new construction, or

       2.     work involved in major modification(s) during a period when one
              or more kilns are not operated, or

       3.     obtaining raw materials, finished or semi-finished products.

Gentlemen:

This will confirm our understanding with regard to filling jobs requiring work
on unusual shifts.

It was agreed that when work in a classification is to be regularly scheduled
for an indefinite period on an unusual shift which substantially overlaps
several hours on each of two regular shifts, the Company will schedule an
employee to work such unusual shift in accordance with the following example:

A Mechanical Maintenance Journeyman is to be regularly scheduled to work five
(5) days per week, 7:00 p.m. to 3:00 a.m. for an indefinite period. As this is
an unusual shift overlapping each of the second and third shifts by several
hours, the Company will seek a volunteer from among the classified Mechanical
Maintenance Journeyman; if there are no volunteers, the junior Mechanical
Maintenance Journeyman will be scheduled to work the unusual shift.

This will confirm our understanding with regard to the applicability of
substance abuse testing of employees.

It is our intention to provide our employees, customers, suppliers and visitors

Narcotics, of the Mine Safety and Health Administration Safety and Health
Standards to Surface Metal and Material Mining and Million Operations, 30 CFR,

Intoxicating beverages and narcotics shall not be permitted or used in or
around mines. Persons under the influence of alcohol or narcotics shall not be
permitted on the job.

Employees suspected with "reasonable cause" of violating the above provision
shall be subjected to the appropriate testing procedures to determine whether
or not such a violation has occurred. The parties shall develop and implement a
procedure to be allowed should such a violation be detected.

Non-employees shall be asked to leave the plant property. A determination will
be made at the time as to whether any other action should be taken regarding
the situation.

1.       such prescription safety glasses are to be used in the course of
         employment with the Company and,

2.       no more than one (1) such examination shall be covered in any calendar
         year.

Gentlemen:

During our recent contract negotiations the Company agreed to the following
policy statement:

In many instances, the Company does offer the senior man upgrades to higher
rated classifications and will continue to do so depending on the
circumstances. The Company, however, declines the Union's request to make
assignments in this manner a contractual requirement. However, if the Union
determines that a repeated Pattern and practice of ignoring seniority on
upgrades has developed concerning a particular individual or group of
individuals, it may grieve such allegation directly to the Plant Manager.

Very truly yours,

whether such rights have been exercised in the past.

                     ARTICLE III - UNION ACTIVITIES/MEETINGS

         Section 1. If and when necessary, in the opinion of both the Company

(1) employee will be excused from any one





                                       2
<PAGE>   4

classification unless the release of two employees from a classification will
not adversely impact costs or operations. An agenda of any subjects to be
discussed at such meeting must be submitted to the Plant Manager not less than
seventy-two (72) hours in advance of a scheduled meeting.

         Section 2. Meetings will be arranged at a time convenient for both
parties to accomplish the purposes set out in this agreement. Any employee who
is scheduled to work during the hours the meeting is held and who attends the
meeting will be compensated by multiplying his regular classified hourly wage
rate by the hours he attends the meeting.

         Section 3. When a meeting is scheduled at which a representative of the
International Union and a representative of the Company from Corporate
Headquarters will attend, any member of the committee who is scheduled to work
the third shift immediately preceding the meeting will be excused from working

regular classified hourly wage rate plus shift differential of the employee who
has attended the meeting.

         Section 4. Any member of the committee who is scheduled to work the
second shift immediately following the meeting will be excused from working the
second shift if the employee has attended the meeting for six (6) hours. In the
event the employee is excused from working the second shift, he will be
compensated by multiplying eight (8) hours at his regular classified hourly wage
rate plus shift differential.

the consent of the Company, may try to adjust a mutual problem. Such consent
will not be unreasonably withheld or delayed.

             the absence of a committee member, try to adjust an existing
             problem.

         b.  Local Union Officers and stewards off duty and representatives of
             the International Union shall, upon permission from the Company, be
             permitted on the Company's premises to investigate grievances.

                             ARTICLE IV - SENIORITY

         Section 1. Seniority is defined as the length of continuous service
with the Company at the Odessa plant, provided, however, that an employee shall
have no seniority rights until after eighty-five (85) days worked.

         Section 2. The following factors shall apply in the awarding of all
jobs:

         a.  Experience, individual skill and ability, and efficient service
             related to the qualifications of the job. (Employees who have
             received repeated disciplinary actions in the twelve (12) months
             prior to bidding the job will not be given consideration for
             advancement.)

         b.  Physical fitness of the applicant.

         c.  Seniority.

         d.  When a. and b. are relatively equal, c. shall apply.

         e.  If the employee selected shall fail to qualify in the judgment of
             the Company after thirty (30) calendar days or less, he shall be
             returned to his former position and the next bidder be given
             consideration. When an employee has bid a job in good faith, the
             Company will give consideration to the employees' request to be
             removed from the job during this period. This 30 day period may be
             extended with the mutual written agreement of the Company and
             Union. When a job cannot be filled in the above manner because of
             the bidder's failing to have the necessary qualifications, the
             Company may fill the job from any source.

         Section 3. For employees on the payroll when this Agreement becomes
effective, seniority is defined as the length of continuous service with the
Company. Seniority rights, once established, shall start from the date of
employment.

         Section 4. An employee's seniority shall be lost only by:

         a.  Discharge for good cause.

         b.  Voluntarily quit.

         c.  Failure to answer recall notice within seven (7) days after
             notification is sent by registered mail to the last address the
             employee has left on file in the personnel office.



                                       4
<PAGE>   6



         d.  If the employee is absent for three (3) consecutive workdays
             without notifying or attaining prior approval from his supervisor
             for such absence, he shall be considered as having voluntarily
             quit.

         e.  During a continuous period of absence, an employee absent due to
             lay off will retain recall rights for a period equal to his
             seniority at the time of lay off not to exceed twenty-four (24)
             months.

         f.  An employee on continuous absence due to disability shall accrue
             seniority and retain recall rights for a period not to exceed
             sixteen (16) months; however, should such an employee be declared
             totally and permanently disabled prior to the sixteen (16) months
             such employee's name shall be removed from the payroll and a
             certified mail notice to this effect will be sent to his last
             address as shown on Company record.

         Section 5. If a vacancy occurs, for which a laid off employee is
qualified, he will be sent a certified mail notice of recall to his last address
provided to the Company Personnel Office.

         a.  If the employee does not respond within a seven (7) day period, or
             refuses the recall, he will forfeit all seniority and his
             employment will be terminated.

         b.  If the employee is reinstated, he shall be credited with seniority
             as prescribed in Section 3 of this Article.

         c.  If an employee is absent because of a disability, he shall only be
             recalled for a vacancy which occurs after he has recovered and is
             physically able to return to work.

         Section 6. An employee in the bargaining unit, who is promoted to a
supervisory position outside the coverage of this Agreement and who subsequently
returns to the bargaining unit, will have his previous bargaining unit seniority
reinstated.

         Section 7. The Company will furnish the Union with a seniority list
every six (6) months.

         Section 8. The Company may at its discretion utilize any hourly
employee to fill a salaried or management position, at any time, without the
employee suffering any loss of seniority or benefits under this agreement,
however, if the employee becomes permanent salaried, he will have no bidding or
bumping rights back to the bargaining unit.

                         ARTICLE V - WORK FORCE CHANGES

         Section 1. Should the Company reduce the work force due to lay off or
any other reason, the Company will give the Union reasonable advance notice of
same and, upon request by the Union, meet to review such reductions.

         Section 2. If the Company determines that the number of employees in
any job classification(s) are to be reduced or eliminated, the decision as to
which employee or employees are to be removed from a job classification, shall
be made by seniority. However, in classifications 5A and above, the Company may
have to deviate from seniority to retain needed skills to ensure efficient
operations.

         a.  Any employee so removed from a job classification in accordance
             with Section 2, above, may exercise his seniority to move into any
             other job classification for which he is qualified. Consequently,
             if this procedure results in the Company declaring that the number
             of employees in the job classification to which the employee has
             transferred must be reduced, the same procedure shall be utilized.
             Any subsequent transfers as a result of the above procedure will
             result with employee(s) being laid off in accordance with Section
             2, above.

         b.  Employees will be recalled in reverse order.

         Section 3. In the event the Company declares a temporary reduction in
the work force due to a curtailment or shutdown because of business or any other
conditions, employees retained to perform necessary work shall be selected on
the following basis:

         a.  Senior employees, whose regular jobs are not required, shall have
             the option of accepting available work for which they are qualified
             or accepting lay off, except that,

         b.  The Company has the right to require that senior employees work
             during the shutdown, if there are no junior employees with the
             necessary qualifications to perform the required work.

         c.  "Qualified" for purposes of this Section 3, shall mean that an
             employee must be able to perform all duties connected with the job
             classification without any training. It is further understood that
             after a three (3) day re-orientation the Company shall require the
             employee(s) to demonstrate his abilities to perform as required
             within the next two work days.


                                       6
<PAGE>   8



         Section 4. The Company's decision concerning qualification as used in
this Article is subject to the grievance procedure.

         Section 5. Should the Company permanently shutdown the present
facilities affording employment to the employees comprising the bargaining unit
(the present facilities shall be deemed to have been permanently shutdown if all
productive facilities are abandoned even though shipping facilities continue to
operate) the Company shall mail a notice informing each affected employee that
his employment with the Company has been terminated because of permanent
shutdown. The notice shall be mailed at least one hundred twenty (120) days
prior to the shutdown to the employee's last address on the Company's personnel
record.


                      ARTICLE VI - PROMOTIONS AND TRANSFERS

         Section 1. When the Company determines that a vacancy exists or a new
job is created, other than laborer, the Company will post a notice of such fact;
such notice to remain posted for a period of at least seventy-two (72)
consecutive hours, excluding Saturdays, Sundays, or holidays. This notice shall
state rates of pay, hours, job requirements and qualifications. Employees who
wish the job shall be considered in the manner provided herein in Article IV,
Section 2, and the successful applicant's name will be posted within seven (7)
days after the bids are opened, except where testing is required. Said delay
will not exceed ten (10) days, unless additional time is agreed to between the
Union and the Company. If an absent employee bids on a job and can reasonably
show he will be available for that job within 120 days of the bid, the Company
may delay filling the job until the employee returns, if that employee is the
successful bidder.

The successful bidder will be placed on the job within as reasonable time as
possible from the date of posting award. In the event of the successful
applicant's failure to qualify in the opinion of the Company, within thirty (30)
workdays on the job, it is understood that said employee is to be restored to
his former position and standing. This 30 day period may be extended with the
mutual written agreement of the Company and Union. The Company will give
consideration to the employee's request to be removed from the job during this
period.

         a.  Laborers who are assigned to fill a job vacancy as a result of no
             one being awarded the job through the bid procedure, may
             subsequently remove himself from his assigned job by:

             (1) Being the successful bidder on a higher classified job posting,
             or


                                       7
<PAGE>   9



             (2) After a period of one (1) year, he may bid on a job of equal
             or lower classification or if qualified replace a less senior new
             employee upon the completion of that employee's probationary
             period.

         b.  This Section does not preclude the Company from hiring new
             employees to fill such a job vacancy, nor does it affect the
             Company's right to temporarily assign any employee to such a job
             vacancy for a period not to exceed 120 days, unless the Company and
             Union mutually agree to a longer period.

         Section 2. An employee may bid to any lower classified job provided he
has held his current job classification for a period of at least twelve (12)
months. Employees must remain in said lower classification for at least twelve
(12) months before he can bid again. An exception to this Section may be
permitted with mutual agreement between the Company and the Union.(Any employee
who bids on the positions of Process Control Operator or Assistant Process
Control Operator must agree to commit to remaining in the position for at least
four (4) years if selected as successful bidder.)

         Section 3. An employee who is temporarily assigned by his supervisor to
work in a higher paid job classification will be paid the rate of such higher
job classification for all time actually worked. An employee temporarily
assigned by his supervisor to perform work in an equal or lower paid
classification will be paid the base hourly wage rate of his permanent
classification.

         Section 4. The Company will treat temporary vacancies caused by
vacations, illnesses, injury or other employee caused absences in the following
manner:

         a.  Choose not to fill the job(s).

         b.  Fill the job on a transfer basis.

         c.  Fill the job on a temporary bid basis. If a job is filled on a
             temporary bid basis, a successful bidder(s) will return to their
             former classification upon completion of the job. Employees may bid
             down only once every 12 months.

         d.  In the event that the Company determines that a job shall become
             permanent, the Company shall post the job as provided in Article
             VI, Section 1.

         Section 5. The Company at its discretion may create new or additional

regular shift, he shall be considered as having been ordered to report, and
shall be given a minimum of four (4) hours' work, excepting when causes beyond
the control of the Company make it impossible to give the required notice, in

Article shall be deemed to have been given when a reasonable effort has been
made by the Company to give such notice orally or in writing to such employee.

             be obligated to provide work nor minimum pay for him.

         Section 11. Whenever a lay off is planned because of a change or

                             ARTICLE VIII - OVERTIME

         Section 1. Overtime is defined as any hours an employee has worked
which are in excess of eight (8) per day or forty (40) hours in a workweek. All
overtime work, as set forth in this section, will be paid at one and one-half
times (1-1/2) the employee's regular straight time hourly rate unless otherwise
specified in this agreement.

         Section 2. Double time. Pay for time worked in excess of twelve (12) 
hours is defined as follows:

         a.  In the event an employee works more than twelve (12) hours in his
             workday he shall be paid for all hours worked in excess of such
             twelve (12) hours at double the straight time hourly rate.

         b.  After an employee has been engaged in work for twelve (12)
             consecutive hours, he shall be paid for all consecutive hours
             worked immediately succeeding and in excess of such twelve (12)
             hours at double the straight time rate.

         c.  In no event shall the two (2) immediately preceding provisions of
             this section be applied to the same hours of work; however, the
             provision which creates the highest earning shall be applied.

         d.  If an employee is being paid at the rate of double time under the
             provisions of this section, and the work continues into the
             employees regular shift the Company may elect to continue to pay
             the employee double time or send the employee home and pay straight
             time pay to the employee for the balance of his/her regularly
             scheduled shift.

         Section 3. Callouts. If an employee is called and reports for work
after leaving the plant at the completion of his regular shift or on his days
off, he shall be paid a minimum of four (4) hours pay at the applicable call out
rate, providing the call out is not consecutive with or contiguous to his
regular shift of work. In such event, the four (4) hour minimum will not be
paid, but in no event will the call out rate be for less than two (2) hours pay.
It is understood that if an employee is called back to work, he may be required
to perform any duties in connection with breakdowns or emergency situations in
addition to the duties for which he was called out.

             worked and all other circumstances other than Sundays.

         c.  Hours worked on call-out work on holidays in excess of eight (8)

         Plus eight (8) hours holiday pay if eligible under this agreement.

         Section 5. Sunday. All overtime hours worked on a Sunday shall be paid
as follows:

         a)  Over eight (8) hours - One and one-half time

         b)  Over twelve (12) hours - Double time

         Section 6. Seventh Day. In the event an employee has actually worked
six (6) complete consecutive days in the work week, the employee shall receive
double the straight time hourly rate for hours worked on Saturday, the seventh
day.

         Section 7. Any hours paid as other than straight time (excluding the
first eight (8) hours at one and one-half time (1.5X) on Sunday) shall be
considered as paid overtime hours and shall not be used for computation of two
(2) or more types of premium pay, duplicated or accumulated on a daily or weekly
basis. There shall be no pyramiding or duplication of overtime or premium pay.
Notwithstanding any other provisions of this section, if an employee begins his
work week on a Sunday the first eight (8) hours worked on that day if paid at

days in a work week or as part of the 40 hours for overtime purposes.

         Section 8. Employees who work in excess of their regular scheduled
working time shall not be laid off to equalize such overtime.

<PAGE>   14

         Section 9. Employees who continue to work in excess of their scheduled

amount of overtime work will not be affected by layoffs.

         Section 11. The Company may schedule overtime as necessary to insure
the continuity of its twenty-four (24) hour, seven (7) day per week continuous
operation as well as overtime necessary to expedite repair of major production
equipment which is down and interrupting production.

         Section 12. The company agrees that, over each calendar year, it will
make a reasonable attempt to allocate overtime equally among employees within
the same classification which the overtime occurs. It is agreed that employees
may not refuse to work overtime unless a reasonable excuse is given as
determined by the Company.

         Section 13. In filling overtime needs, the Company will contact the
classified employee(s), who is (are) qualified in accordance with the
understanding in Section 9 of this Article.

         a.  In the following procedure, the employee will only be contacted one
             (1) time and he must immediately accept or decline, except as
             otherwise determined by subsection c. of this Section 10.

         b.  An employee working on a job shall be given first consideration if
             any overtime is needed to finish the job.

         c.  When it is determined that overtime work is required in a
             classification(s), Management will make every effort to obtain
             necessary workers by asking the lowest person(s) in overtime to
             work, until a sufficient number(s) has been obtained. If refusals
             result in the Company not being able to obtain sufficient employees
             in the affected job classification(s), the required number of such
             classified employees with the least amount of overtime worked will
             be expected to work the necessary overtime or be subject to
             progressive discipline.

         d.  All worked and/or refused overtime will be charged toward
             equalization records.

         e.  All employees are expected to work a reasonable amount of overtime.

         f.  In the event the overtime procedure fails to obtain the necessary
             employee(s) needed to work, the Company may perform the work in any
             way it deems necessary.

         Section 14. If an employee does not work a regularly scheduled workday

purposes unless that day is compensated by the Company under any provisions of
this Agreement or the employee is on approved leave of absence for union
business as permitted under this Agreement.

shift worker, then the premium rate applies.

         Section 4. All consecutive hours (exclusive of meal periods) worked by
an employee who normally begins work at a time specified in the preceding

         count toward the calculation of any penalty or premium pay section of
         this Agreement including, but not limited to daily or weekly overtime.
         Any time spent outside the hours the employee is scheduled to work
         shall not count toward the calculation of any penalty or premium pay

employees of the Company. Shoes will have a minimum of a six-inch (6") top.
Full-time permanent employees will become eligible for safety shoes'

in the amount of $180.00 each year to each employee for reimbursement of safety
shoes.

         Section 4. A medical examination of any employee may be made when, in
the opinion of the Company, an examination is necessary to protect the health or
safety of the employee involved, or the health or safety of other employees.

         Section 5. All injuries must be reported to the foreman on the shift
they occur prior to leaving the plant, unless the nature of the injury is such
that the employee is unaware of the injury. If an employee becomes injured on
the job and in the opinion of a qualified medical doctor (M.D.) he is unable to
return to work, he shall be paid for any wages lost that day only.


                         ARTICLE XVI - LEAVE OF ABSENCE

returning to work with the Company. Upon returning to work, such employee will
be reinstated on his former job, providing it is still in existence; if not, he

the existing bidding procedure, or by bumping. The Company agrees to consent to
the absence of no more than one (1) employee at any time under this article.

<PAGE>   23

         Section 2. Any employee absent from work in accordance with the
foregoing provisions shall not lose seniority, wage rate, or position, if
physically fit upon return to work. Except as provided for in section 2 of this
article, should an employee accept a position for wages or salary while on leave
of absence, such employee shall lose seniority, and if re-employed, must be
treated as a new employee.

         Section 3. A leave of absence will be granted to employees to attend
union conventions or other like union activities without loss of seniority and
other employment rights and benefits. The Union will give the Company written
notice of at least ten (10) days of any anticipated leave. Not more than two (2)
employees may be absent for such purposes at any one (1) time. If two employees
are from the same department, both will be excused only if a qualified
replacement is available in the sole judgement of the Company.

         Section 4. An employee who has exhausted all eligible vacation may
request in writing an unpaid personal leave for up to thirty (30) calendar days
for good and significant personal reasons not covered under the Family and

the Company.

         Section 2. Should an employee be called out on a scheduled off day and
he continues to work for more than ten(10)consecutive hours, Section 1 of this
Article will become applicable.


                       ARTICLE XVIII - GRIEVANCE PROCEDURE

         Section 1. Should differences arise between the Company and the Union,
or an individual employed by the Company, as to the meaning and application of
the provisions of this Agreement, an earnest effort shall be made by the parties
to settle such differences promptly and in the following manner:

         STEP I. The complaint, within seven (7) calendar days of its
         occurrence, or the occurrence of the matter out of which the complaint
         arises, may be taken up by the employee involved, with or without Union
         representation, with his foreman. The employee shall state the


                                       22
<PAGE>   24



                  specific article(s) and paragraph(s) of the Contract that is
                  alleged to have been violated in order for the grievance to be
                  considered and processed.

         STEP II. If no satisfactory settlement is reached in Step I, the matter
         shall be reduced to writing and presented to the Plant Manager or his
         delegate within five (5) days from the date of the meeting with the
         foreman. At the time of presentation, or within thirty (30) days, the
         Plant Manager or his delegate will meet with the Grievance Committee to
         hear and discuss the grievance. The Company shall answer the grievance
         in writing within five (5) days after said meeting. The employee shall
         state the specific article(s) and paragraph(s) of the Contract that is
         alleged to have been violated in order for the grievance to be
         considered and processed.

         STEP III. If no agreement is reached in Step II, The Committee may,
         within five (5) days of the receipt of the above answer, refer the
         matter to higher officials of the Company and the Union who may attend
         such a meeting. Upon request by the Union a meeting will be held within
         forty-five (45) days of such request. The Company shall answer the
         grievance within five (5) days after said meeting.

         STEP IV. A grievance arising out of the terms of this Agreement, which
         has been properly processed through the Grievance Procedure within the
         time limits specified and not settled, may be submitted to arbitration
         in accordance with the provisions of Section 5. Arbitration.

         Section 2. Except for Section 1, Step I., the time limits referred to
in this Article exclude Saturdays, Sundays and holidays.

         Section 3. Any grievance not presented or appealed within the time
limits provided, unless mutually agreed to extend the time, shall be considered
settled on the basis of the decision which was not appealed and shall be final
and binding on the parties involved.

         Section 4. Grievances presented in any of the regular steps set forth
and not answered within the time specified or as the same may be extended by
mutual agreement shall be considered appealed to the next step of the grievance
procedure.

         Section 5. Arbitration

         a. Any grievance not settled in Step III above may be referred to
         arbitration. Notice to refer a grievance to arbitration shall be given
         in writing within ten (10) days after being notified on the decision
         rendered in Step III or the matter will be considered closed. Only one
         (1) grievance may be submitted to or under review by any one (1)
         Arbitrator at any one time unless by the prior mutual written consent
         of the parties.


                                       23
<PAGE>   25



         b. In the event the parties are unable to agree upon an Arbitrator
         within seven (7) days after arbitration is invoked, then they shall
         jointly petition the Federal Mediation ad Conciliation Service, which
         shall submit a panel of seven (7) qualified arbitrators, and the
         parties shall select a single arbitrator from such panel. The
         arbitrator shall be appointed by mutual consent of the parties hereto.
         If the arbitrators included in this panel are unacceptable to either
         party, a second panel shall be requested from the Federal Mediation and
         Conciliation Service and a single arbitrator selected from this panel.
         The Union shall strike the first name.

         c. Any grievance referred to arbitration shall be heard as soon as
         possible and a decision rendered within thirty (30) days of the hearing
         or the date of postmark of the post hearing briefs. The Arbitrator
         shall have no power to add to or subtract from or change, modify or
         amend any of the provision of this Agreement. The decision rendered by
         the Arbitrator will be final and binding upon the Union, the Company,
         the grievant and all employees covered by this Agreement. The
         Arbitrator selected pursuant to this Article shall interpret and apply
         the terms of this Agreement; he/she shall not substitute his/her
         discretion and judgment for that of the Company.

         d. It is expressly agreed that no Arbitrator shall have the authority
         to decide any matter involving the exercise of a right reserved to
         management under this Agreement.

         e. Each party hereto shall pay the expense incurred in the presentation
         of its own case, and the expenses incident to the services of the
         Arbitrator, including the cost of the transcript for the Arbitrator,
         shall be shared equally by the Company and the Union. If either party
         request a copy of the transcript that copy will be paid for by the
         party requesting it.

         Section 6. Any grievance growing out of a discharge or suspension must
be submitted in writing by the aggrieved employee directly to the Union and from
the Union to the Director of Industrial Relations or Plant Manager or designee
within forty-eight (48) hours of the discharge or suspension or it will not be
recognized and the action taken shall be final.


                      ARTICLE XIX - INCAPACITATED EMPLOYEES

         Section 1. Any employee who becomes permanently incapacitated and, on

Union member, the Company may discharge or otherwise discipline any employee who
authorizes, causes, engages in, sanctions, recognizes, or assists in any
violation of this Article. The Company will not engage in any lockouts during
the term of this Agreement.


                            ARTICLE XXI - LEGISLATION

         In the event laws are passed which conflict with any provisions of this
Agreement, or any provision or provisions of this Agreement shall be declared
void in whole or in part, or shall be declared not to affect any employee or
employees by law or final decision by competent authority, then such provisions
or parts thereof shall be eliminated here from and the matter covered by such

                                   APPENDIX C

         Section 1. - Pension


         Normal Retirement Pension.

         The monthly amount of the normal retirement pension on a single life
basis for retirements after March 31, 1991 and before April 1, 1996, shall be
the greater of (a) or (b).

         (a)      $24.00 multiplied by the participant's period of service (in
                  years and fractions thereof), but only for service prior to
                  April 1, 1996.

         (b)      an amount computed as follows:

                  (i)      1% of the participant's average monthly compensation
                           multiplied by his period of service (in years and
                           fractions thereof); plus

                  (ii)     .65% of the participant's average monthly
                           compensation to the extent that it exceeds covered
                           compensation multiplied by his period of service (in
                           years and fractions thereof) to a maximum of 35
                           years.

         Average monthly compensation shall be the result obtained by dividing
total base pay (up to 2,080 hours of base pay each year) received in each of
five consecutive plan years by 60. (Effective 08/01/94 gainsharing earnings will
be included as part of base pay.) Covered compensation for a plan year means
1/12th of the average of the Social Security taxable wage bases for the 35-year
period ending with the last day of the calendar year in which the participant
attains (or will attain) Social Security retirement age (generally age 65).

         The monthly amount of the normal retirement pension on a single life
basis for retirements after March 31, 1996 shall be the greater of (a)
calculated only as of July 31, 1996, or (b).

         The pension formula used by the Southdown, Inc. Pension Plan adjusts
automatically for wage inflation and is designed to achieve along with social
security a wage replacement percentage of 50% - 60% for a 30-year employee.

Early Retirement

         A participant may elect to retire and commence receiving a pension
benefit prior to attainment of normal retirement age as follows:



                                       32
<PAGE>   34

         With respect to the minimum benefit calculated in (a) above (the
"Minimum Benefit"), any participant who has 10 years of service and has attained
55 years of age and who elects to retire and commence receiving pension benefits
prior to his 65th birthday shall be entitled to receive a pension amount equal
to his Minimum Benefit reduced by three-tenths of one percent (0.3%) for each
month by which his actual retirement date precedes normal retirement date.

         Any participant who has accumulated a minimum of 30 years continuous
years of service may elect to retire and immediately commence receiving pension
benefits equal to the Minimum Benefit without regard to attained age.

         With respect to the maximum benefit calculated in (b) above (the
"Maximum Benefit"), any participant who has 5 years of service and has attained
55 years of age and who elects to retire and commence receiving pension benefits
prior to his 65th birthday shall be entitled to receive a pension a Maximum
Benefit reduced by five-ninths of one percent for each month up to 60 months by
which his actual retirement date precedes normal retirement date, and
additionally by five-eighteenths of one percent for each month over 60 months by
which his actual retirement date precedes normal retirement date.

Plan Termination

         In the event the plan is terminated, that the accrued benefit of each
participant will become fully vested and nonforfeitable. Assets will be
allocated in accordance with Section 4040(a) of ERISA. Any assets in excess of
amounts allocated in accordance with Section 4044(a) of ERISA would revert to
the Company subject to applicable IRS and PBGC rules.

         Subject to ERISA Section 4044(a), and any applicable regulations of the
IRS and PBGC, distribution of benefits to participants on plan termination would
be made, in whole or part, to the extent that no discrimination in value
results, in cash, in securities or other assets in kind, or in nontransferable
annuity contracts.

                                   APPENDIX D

                         SICKNESS AND ACCIDENT BENEFITS




If a permanent employee (non-probationary/non-temporary) is absent from work due
to disability, sickness and accident benefits are payable. The disability must
prevent the employee from performing the duties of the job because of a
non-occupational sickness or injury. This benefit is payable if confined to a
hospital or home.

is hospitalized as an in-patient or absent five (5) consecutive work days), the
disability benefits are payable at a rate of fifty-five dollars ($55) per day
for a maximum of five days per week. A disabled employee may receive weekly
sickness and accident benefits during the period of disability, not to exceed
five (5) months. It is the employee's responsibility to make application for
this benefit and the attending physician must document the nature of the
disability and expected date of return to work.

No benefits shall be payable for the following:

         1.       disability which you are not under the direct care of a
                  licensed physician;

         2.       sickness or injury which is purposefully self-inflicted while
                  sane or insane;

         3.       disability due to an injury arising out of the course of
                  employment;

         4.       disability due to disease which benefits are payable under
                  Worker's Compensation, Occupational Disease or similar law.

This benefit terminates upon retirement or upon termination of employment.

         Retirement Medical Insurance

Dear Mr. Adams:

In our previous labor agreement, the Company agreed to increase its monthly
contribution toward future retiree medical benefits by 7.5% over the capped 1993
cost levels. Based on our discussions during the 1998 negotiations, the Company
agrees to increase its contribution up to 2.5% on an annual basis for any
calendar year in which the Company requires an increased contribution for
medical benefits by retirees during the life of the new agreement.

Dear Mr. Adams:

Pursuant to our discussions during 1998 Odessa Labor Contract Negotiations, the
Company agrees to continue the existing practice regarding holidays that occur
during employees' vacation. That practice is, that if an employee takes a week
of vacation during which a holiday occurs and the employee wants the preceding
Friday or following Monday off in lieu of holiday pay, that employee may request
it of his supervisor. If the supervisor grants it, the employee may take it,
otherwise the employee does not get the additional day off for the holiday.

August 28, 1998




Mr. Theodore "Nick" Adams
International Representative - IBB
6619 East 80th Street North
Owasso, Oklahoma  74055


Dear Mr. Adams:

During the 1998 Odessa Labor Contract negotiations the company agreed to make
certain changes contingent upon the ratification of the new Labor Agreement by
August 31, 1998. Those changes are listed below:

         -        Article 8, Section 4 - Overtime pyramiding

         -        Pay for time lost by negotiation committee up to 40 hours per
                  week

         -        $1,000.00 ratification bonus

         -        Retroactive calculation of base wage increases to August 1,
                  1998.

This confirms that these tentative agreements will be withdrawn if the union
advises the company that the Agreement failed ratification by August 31, 1998.
We ask that the union committee advise Steve Bryan of the result the week of
August 31, 1998.

Sincerely,



Bernard M. Reuland

      full continuous service credit from date of original hiring.

(d)   Employees covered by this Agreement shall lose their entire seniority if:

      (1)  They voluntarily quit.

      (2)  They are discharged for cause and not re-hired within six (6) months
           or re-instated.

      (3)  "During a continuous period of absence, an employee absent because
           of layoff or disability shall maintain and accumulate seniority for
           three years or for a period equal to 50% of seniority attained at
           the start of such absence, whichever is greater, thereafter he will
           accrue no further seniority during such period of absence.
           Thereafter, when a vacancy occurs, for which a laid off employee is
           qualified, he will be given registered mail notice of recall at his
           last address as shown on company records, to which he must respond
           within seven days of receipt of notice. If the employee is
           reinstated, he shall be credited with seniority as prescribed above;
           if the employee does not respond or refuses the recall, he will
           forfeit all seniority and the company may fill the vacancy with a
           new employee. The above procedure shall also apply to an employee
           absent because of disability, except that he shall only be recalled
           for a vacancy which occurs after he is physically able to return to
           work. However, the above shall not modify Article IV (d) (5) or
           Article V (a) (7) (e) second paragraph."

           Any employee detained from work on account of sickness or for any
           other good reason shall notify the Plant Manager or his Foreman,
           before the start of his shift. Any employees absenting themselves
           from work for five (5) consecutive days without good and
           satisfactory reason may be discharged and dropped from the seniority
           list and payroll of the Company. Repeated absence of less than five
           (5) days shall be subject to a progressive disciplinary program, and
           the Local Union will receive communications pertaining to each step
           of disciplinary action within one working day excluding Saturdays,
           Sundays and holidays of any action taken.

      (4)  An employee's seniority shall be broken and his employment
           terminated effective on the date of his acceptance of Termination
           Benefits under the provisions of the Supplemental Unemployment
           Benefit Plan Agreement.

      (5)  In the event the installation of new equipment, or the shutting down
           of the plant or a subdivision thereof, results in layoffs which can
           be termed of a permanent nature, the employees permanently laid off
           shall retain and accumulate seniority for two (2) years: after said
           two (2) years such employees shall retain, but not accumulate
           seniority until they are terminated in accordance with the Labor
           Agreement.

(e)   A leave of absence for the purpose of accepting a position with the
      United Cement, Lime, Gypsum and Allied Workers Division, at the local,
      district or international level, or the AFL-CIO or any of its subordinate
      bodies, shall be available to not more than three (3) employees from each
      plant at any one time. Applications for such leave shall be submitted to
      the Company in writing thirty (30) days prior to the effective date of
      such leave to permit proper provisions to be made to fill the job to be
      vacated. Leaves of absence for this purpose shall be for an indefinite
      period. During such leave, seniority shall accumulate. Group insurance
      coverage shall be suspended after thirty (30) days of such leave. All
      insurance coverages will be reinstated upon returning to work with the
      Company. Upon returning to work, such employee will be reinstated on his
      former job, providing it is still in existence; if not, he shall be
      eligible to apply for any job within the bargaining unit by means of the
      existing bidding procedure or bumping.

(f)   Subject to the approval of the Company, employees requesting a leave of
      absence in writing for personal reasons may be granted leaves of absence
      not to exceed thirty (30) Calendar days.

(g)   The Company shall attach to the Agreement a list of employees' seniority
      rights, in order of the date of hiring, as well as a list of the
      probationary employees. (see Appendix A (1))

(h)   Temporary summer employees may be employed by the Company from May 1st
      through September 30th in order to facilitate filling of vacancies caused
      by vacations during these months. Employment of summer employees will be
      subject to the following conditions:

      (1)  No summer employee will be hired when any regular employee is on
           layoff or drawing short work week benefits.

      (2)  All summer employees will be required to join the Union under the
           same terms and conditions as required in Article II, Sections (b)
           and (c) of the Agreement.

      (3)  All summer employees must sign an appropriate form which will spell
           out the terms of their employment including but not limited to an
           agreement to commence their employment on a specified date and
           terminate their employment on a specified date.

      (4)  The term of employment will not be changed, altered or extended
           unless mutually agreed to by both the Company and the Local Union
           Committee.

<PAGE>   7


      (5)  Summer employees shall not accumulate seniority nor be eligible to
           bid on any new job or vacant job which may occur during their term
           of employment.

      (6)  A summer employee will not have any vacation rights.

      (7)  Summer employees will not participate in the Company's pension, SUB
           and insurance programs.

      (8)  If college students or graduated high school seniors enrolled in a
           college are available, temporary summer hires will be limited only
           to these students.

      The above will be in full force and effect, except that if any portion is
      found to be contrary to any Federal, State or local law, it shall be
      changed to comply with said law.

                                   ARTICLE V

                                  JOB SECURITY

(a)   (1)  Whenever the installation of mechanical equipment, change in
           production methods, the installation of new or larger equipment, the
           combining of jobs or the elimination of jobs, will have an effect on
           the job status of one or more employees. the Company will give the
           Union reasonable advance notice of same, and upon request by the
           Union will promptly meet with the Union to review and explore the
           effects of such installation or installations or change or changes
           upon the working force.

      (2)  Employees will not be terminated by the Company as a result of
           mechanization, automation, change in production methods, the
           installation of new or larger equipment, the combining of jobs or
           the elimination of jobs.

      (3)  Whenever an employee is no longer needed on his regular job as a
           result of Circumstances described in (1) above, such employee will
           have up to seven (7) days from date of notification to exercise his
           right to apply for any jobs within the bargaining unit on which an
           incumbent has less seniority, and for which he could reasonably be
           expected to qualify within a ninety (9O) day on-the-job training
           period, unless the employee applying for such job is disqualified
           due to physical reasons. The rate of pay for such employee shall not
           be less than ninety-five percent (95%) of the rate for the regular
           job from which he was displaced, irrespective of the rate of the job
           which he applies for and obtains. The ninety-five percent (95%) of
           rate protection shall apply for a minimum period of one (1) year, or
           a period equal to one-third (1/3) of an employee's seniority up to a
           maximum of five (5) years. If the affected employee is tendered
           training for a job 


7
<PAGE>   8


           which he could be reasonably expected to qualify for within a ninety
           (90) day on-the-job training period and refuses, he will not be
           entitled to any rate protection unless he has a bona fide reason for
           refusing. If an employee on ninety-five percent (95%) rate
           protection subsequently bids on and is awarded a lower rated job, he
           shall lose his rate protection.

      (4)  Employees affected by the application of the foregoing procedure
           shall have and may exercise and same rights for retention and
           on-the-job training in accordance with their seniority status and
           the ninety-five percent (95%) rate guarantee shall also be
           applicable to them.

      (5)  Employees who do not apply for and/or obtain a job in accordance
           with the provisions of (3), including employees displaced from their
           jobs but whose seniority status does not permit then to utilize job
           retention rights under the provisions of (3) or (4), will be placed
           on layoff status with recall rights in line with their seniority
           status for job vacancies which may thereafter occur.

      (6)  The provisions of (3) of this Section do not apply to displacements
           or layoffs resulting from production curtailments, except that
           employees laid off and not recalled when production is resumed
           following Curtailment will be entitled to the same rights as
           employees affected by the preceding (3).

      (7)  Should the Company permanently shutdown the present facilities
           affording employment to the employees comprising the bargaining unit
           (the present facilities shall be deemed to have been permanently
           shutdown if all productive facilities are abandoned even though the
           shipping facilities continue to operate), the Company shall mail a
           notice informing each affected employee that his employment with the
           Company has been terminated because of the permanent shutdown. The
           notice shall be mailed at least ninety (9O) days prior to the
           shutdown to the employee's last address on the Company's records.
           Each employee who is mailed said notice shall have the following
           options:

A.    An employee who is not eligible for a normal (excluding 30-year
      retirement pension) or late retirement pension may elect to transfer to
      another operation of the Company covered by a collective bargaining
      agreement with the Union in accordance with paragraph 8 or paragraph 9.
      Any transfer pursuant to paragraph 8 or paragraph 9 will occur not later
      than three years after the last day the employee worked. An employee
      awaiting transfer shall be placed on layoff and shall receive S.U.B.
      layoff or reduced layoff benefits provided the eligibility and other


8
<PAGE>   9


      requirements of the S.U.B. Plan are met. An employee may void his
      election to transfer at any time during the three-year period. If the
      employee is eligible for an immediate pension at the time he voids his
      election to transfer, he shall retire, effective the date he voids his
      election, under the pension plan in effect at the time of the permanent
      shutdown. An employee may also void his election in order to apply for
      S.U.B. termination benefits.

B.    An employee who is eligible for an immediate pension at the date of the
      permanent shutdown shall retire as of the effective date of the permanent
      shutdown except:

      1.   An employee whose combined age and years of service equal 62 or more
           but less than 65 may elect layoff until his combined age and years
           of service equal 65 at which time the employee shall retire and
           receive a permanent shutdown pension. The pension plan in effect at
           the time of the permanent shutdown shall determine the retirement
           benefits payable to the employee. An employee who elects layoff
           under these conditions shall receive S.U.B. layoff or reduced layoff
           benefits provided the eligibility and other requirements of the
           S.U.B. plan are met.

      2.   An employee who is eligible for an immediate pension other than a
           normal or late retirement pension and who elects to transfer to
           another operation of the Company shall not retire unless the
           transfer is not accomplished.

      3.   An employee shall not be required to retire under a disability
           retirement pension earlier than he would otherwise be required to
           retire if the Company had not permanently shutdown the facilities.

           An employee who retires under the Pension Plan may also be entitled
           to receive S.U.B. Termination Benefits in accordance with the terms
           of the S.U.B. Plan.

C.    The employee may elect S.U.B. Termination Benefits in accordance with the
      terms of the S.U.B. plan at any time within one (1) year after notice of
      termination has been mailed to him.

      An employee other than an employee who is eligible for an immediate
      pension may elect layoff prior to submitting his application for S.U.B.
      Termination Benefits and shall receive S.U.B. layoff or reduced layoff
      benefits provided the eligibility and other requirements of the S.U.B.
      Plan are met.

<PAGE>   10


D.    If the facilities which have been permanently shutdown are re-opened by
      the Company within three (3) years of the date of the permanent shutdown,
      an employee who has retired under the Pension Plan shall be eligible for
      recall in accordance with his seniority status at the time of the
      permanent shutdown. An employee who has elected S.U.B. Termination
      Benefits shall also be eligible for recall in accordance with his
      seniority status at the time of the permanent shutdown. Any pensioner who
      has received S.U.B. Termination Benefits and accepts recall and any
      former employee who has received S.U.B. Termination Benefits and accepts
      recall shall repay said Termination Benefits to the S.U.B. Trust Fund or
      to the Company, whichever was the source of the Termination Benefits, in
      accordance with the S.U.B. Plan Agreement. Any employee who accepts
      recall shall have his previously accumulated seniority rights, pension,
      S.U.B., insurance, and vacation credits as of the last day the employee
      worked or at the date of permanent shutdown, whichever occurs later,
      reinstated on the date he returns to work.

E.    An employee who is not eligible for an immediate pension may elect layoff
      and shall receive S.U.B. layoff or reduced layoff benefits provided the
      eligibility and other requirements of the S.U.B. Plan are met.

      The employment rights of any employee on layoff shall terminate three (3)
      years after the last day the employee worked and the employee's seniority
      shall be broken.

F.    An employee's participation in the group insurance program shall
      terminate effective the day following the last day the employee worked
      and pending claims shall be processed in accordance with the terms of the
      existing group insurance program. No employee shall be eligible for
      holiday pay or vacation pay other than vacation pay due after the last
      day the employee worked or the date of the permanent shutdown whichever
      occurs later. No employee shall accumulate credited service under the
      Pension Plan after the last day the employee worked or the date of the
      permanent shutdown, whichever occurs later.

      (8)  In the event the Company constructs a new plant that will affect the
           employment status of employees in the Company's plant or plants
           comprising this bargaining unit, such employees shall be given an
           opportunity to make application for employment in the new plant
           before it starts operation, and such employees shall be given
           preferential employment rights for the highest rated job the
           employee is capable of performing. Such an employee shall transfer
           with him all his previously accumulated pension, S.U.B., insurance
           and vacation credits. His seniority rights at the former plant shall
           terminate upon his establishment of seniority rights in the new
           plant.


10
<PAGE>   11


      (9)  When an employee has been laid off or displaced because of permanent
           changes in the working force or because of a plant closing, he may
           make written application within fifteen (15) days of layoff or
           displacement for employment in another plant of the Company and he
           shall be given preferential employment rights for job openings at
           such other plant, providing such employee is capable of performing
           the job that may be available at such other plant of the Company.
           Any employee so transferring from one plant to another of the
           Company shall retain his previously accumulated pension, S.U.B.,
           insurance and vacation credits. His seniority rights at the former
           plant shall terminate upon his establishment of seniority rights in
           the plant to which he transferred.

      (10) Employees transferring from one plant to another as provided in (a)
           (7), (8) and (9) of this Article will receive a moving expense
           allowance. The Company will reimburse each employee for actual
           moving expenses incurred to move furniture and other household goods
           up to a maximum of $1,000 per employee.

(b)   When a production curtailment or a plant shutdown causes a reduction in
      personnel in a department or throughout the plant, a senior employee
      whose regular job is not required shall have the option of accepting
      available work for which he is qualified or accepting layoff. A senior
      employee who is eligible to accept layoff shall be recalled (1) when his
      job resumes operation, or (2) when the plant starts up, whichever occurs
      sooner providing his seniority permits such recall. A senior employee who
      elects to accept available work shall be entitled to:

      (1)  First, bump any junior employee whose job is in the same department
           as the senior employee provided that the senior employee previously
           held the job permanently or temporarily pursuant to Article VII,
           Section (i) (3), for a sufficient period of time to demonstrate his
           ability to satisfactorily perform the job as it is constituted at
           the time of the production curtailment or plant shutdown, or if no
           jobs are available.

      (2)  Second, bump any junior employee whose job was previously held by
           the senior employee permanently or temporarily pursuant to Article
           VII, Section (i) (3), for a sufficient period of time to demonstrate
           his ability to satisfactorily perform the job as it is constituted
           at the time of the production curtailment or plant shutdown; the
           senior employee must attempt to bump into a job that he previously
           held in the reverse order of his promotions. In other words, he must
           first attempt to bump into the job he held immediately prior to his
           present job.

11
<PAGE>   12


      (3)  If step (1) or (2) above would result in an employee becoming a part
           of the labor crew, he may exercise the bumping rights set forth in
           (4) below prior to entering the labor crew.

      (4)  Third, a senior employee can bump a junior employee on a plant-wide
           basis except for any maintenance job, any laboratory job, or the
           control room operator's job, provided he is qualified to perform the
           job immediately.

           The above bumping procedure must occur in the order designated.
           However, an employee may bump the most junior employee in a
           particular classification on a particular shift rather than being
           forced to bump the most junior employee holding that particular
           classification without regard to the shift the employee would have
           to work on. Any junior employee who is displaced by a senior
           employee shall have the same rights as the senior employee set forth
           herein. After the bumping is completed, the Company has the right to
           require a senior employee to perform available work during the
           curtailment or shutdown if there is no junior employee with the
           necessary qualifications to perform the work.

           A plant shutdown is defined as a period during which none of the
           clinker burning units are producing.

           The wage rate paid during a production curtailment shall be the wage
           rate of the job performed. An employee who works on two (2) or more-
           jobs in one day shall receive the highest wage rate for only the
           time worked on the higher rated job. However, should the employee
           work on a higher rated job(s) four (4) hours or more in the work day
           he shall receive the higher rate of pay for the entire day.

           During periods of plant shutdowns when employees are needed for
           maintenance, repairs, or work on plant alterations, the wage rate
           paid to employees who are retained for work during the first
           forty-five (45) days of a plant shutdown shall not be less than the
           employee's regular straight-time wage rate normally paid when the
           plant is producing. After forty-five (45) days, the wage rate paid
           shall be the wage rate of the job performed. An employee who works
           on two (2) or more jobs in one day shall receive the highest wage
           rate for only the time worked on the higher rated job. However,
           should the employee work on a higher rated job(s) four (4) hours or
           more in the work day he shall receive the higher rate of pay for the
           entire day. The ninety-five percent (95%) rate protection is not
           applicable to any bumping under this procedure.

           When the Company determines that additional jobs are required during
           or following a production curtailment or a plant 


<PAGE>   13


           shutdown and the work force must be increased, the manner in which
           the reduction of forces took place will be reversed in order of
           seniority to those employees who previously held the job for a
           sufficient period of time to demonstrate his ability to
           satisfactorily perform the job as it is constituted at the time of
           the production curtailment or plant shutdown.

           In the event that during a production curtailment or a plant
           shutdown an employee bids for and is awarded another job, he shall
           lose all rights pertaining to the job the employee previously held.

           Subsection (b) above shall not add to, subtract from or otherwise
           modify the maintenance training agreement by and between the Company
           and the International and/or Local Union negotiated after the
           effective date of this Agreement.

           See Appendix C for definitions of departments as applied to this
           Article.

(c)   (1)  The Company agrees to post a notice at least one week in advance of
           an intended shutdown. This shall not apply to emergency shutdowns
           due to reasons beyond the Company's control: such as power failure,
           labor disputes, fire, flood, or acts of God.

      (2)  The Company will post a notice seven (7) days in advance indicating
           when a production curtailment or plant shutdown will end.

      (3)  Whenever a layoff is planned because of a change or reduction in
           plant production requirements, the Company will, not less than seven
           (7) calendar days prior to the effective date of the layoff, post a
           bulletin stating the expected extent of such layoff, and the
           expected effect on the work focus. In the event the required notice
           is not given in accordance with the above, the Company will pay the
           laid-off employee(s) the scheduled time lost at the applicable
           straight time shift rate. The seven (7) calendar day period shall
           commence on the completion of the third shift following the day in
           which the notice was posted. The foregoing does not apply to
           disciplinary layoffs and layoffs because of curtailment made
           necessary by disaster or emergency conditions affecting the ability
           of the Company to physically operate the plant.

(d)   Company personnel excluded from the bargaining unit shall not perform
      bargaining unit work except in an emergency, endangering life or
      property: for training or instruction purposes for testing, diagnosis,
      analysis or when necessary to prevent disruption of the flow of
      operations or when necessary to meet the interest of efficient
      operations.

      Should a Company person excluded from the bargaining unit violate this
      commitment, the Company will be required to pay to the effected worker or
      workers double time (his or their) regular straight time hourly rate for
      anytime worked by persons not included in the bargaining unit, with a
      minimum of four (4) hours pay. If there is no affected worker, the
      penalty for such work shall be paid to the worker lowest in overtime in
      the classification and/or department.

(e)   Any employee who becomes incapacitated and, on the basis of competent
      medical opinion, cannot perform the duties of his regular job may
      exercise his plant seniority through the bumping procedure to move to
      another position within the bargaining unit at the plant for which he
      could qualify within a reasonable period of time, but not to exceed
      ninety (9O) days. This in no way affects the bidding rights of the
      employee. The ninety-five percent (95%) rate protection is not applicable
      to bumping under this procedure.

      Any employee who is displaced by an incapacitated employee pursuant to
      paragraph (e) of this Section may exercise his plant seniority to bump
      into another position within the bargaining unit at the plant for which
      he is qualified in the same manner as provided for in the job bidding
      procedures.

(f)   As soon as the Company knows that there will be a job elimination Tit
      will notify the Union as to when the elimination will take place.

                                   ARTICLE VI

                            EMPLOYMENT AND PROMOTION

(a)   All vacancies and new jobs created shall be posted no later than the
      eighth (8th) day following the date the vacancy occurred or the new job
      was created. Said vacancies and new jobs shall be posted for seven (7)
      days to allow any employee in a classification whose straight time hourly
      rate is less than the bid job to make application in writing for such
      job. See Attachment "A". The Company will consider every application in
      terms of:

      (1)  Seniority

      (2)  The applicant's skill and ability and physical fitness measured
           against the requirements of the job.

           Where two or more applicant's qualifications in (2) are relatively
           the same, seniority shall govern.

           If an employee proves unsatisfactory, he shall be reinstated to his
           previous job, and the Company will consider the remaining applicants
           in accordance with the above.

14

<PAGE>   15


           This article does not require the Company to award a job to any
           applicant if no applicants are qualified to perform the work.

           The Company has the right to assign any employee to fill a new job
           or to fill a vacancy until the job has been awarded.

           The Company will meet with the Local Union Committee to explain its
           decision when the Company awards a job to a junior applicant. Any
           senior applicant shall have the right to challenge the Company's
           award by filing a grievance in a timely manner. Any employee
           reinstated to his previous job shall have the right to challenge his
           disqualification by filing a grievance in a timely manner.

(b)   Prior to the time that bids are removed from the bid box, an employee may
      withdraw his bid by placing a withdrawal slip in the bid box.

      Bid boxes will contain two (2) locks; one for the Company and one for the
      Union.

(c)   Any employee can give the Company a letter which lists in order of
      preference all jobs that the employee wishes to bid if such jobs become
      vacant and are posted while the employee is absent from work because of a
      scheduled vacation or due to an illness or an injury. Furthermore, if the
      Company creates and posts a new job during such period that an employee
      is absent from work due to an illness or an injury, the Company will use
      its best efforts to notify the employee about such job no later than the
      last day such job is posted to learn whether the employee wishes to bid
      on the job.

(d)   An employee who bids for and is awarded a permanent job can bid for the
      same permanent job even though it is in the same bracket if the
      employee's sole reason is to work different days and/or shifts.

(e)   If the employee previously held the classification on a bid basis or
      temporary basis (including step up or labor fill in) he will have no
      option, unless the job has been substantially changed in which case he
      will have a five day option. An employee who has not held the
      classification on any basis will be given a five day option.

(f)   An employee who bids and is awarded a job shall receive the rate of the
      new job when he moves on to the job or on the Sunday following two full
      weeks subsequent to the date of the award, whichever comes first.

(g)   See Appendix F for examples.

                                  ARTICLE VII

                               WORKING CONDITIONS

(a)   Hours of work

      Eight (8) hours shall be the regular work day and forty (40) hours shall
      be the regular work week. This shall not constitute a guarantee of work.
      The work day shall commence with the beginning of the morning shift and
      work week shall commence with the beginning of the morning shift on
      Sunday. The starting and quitting times for the shifts shall not be
      permanently changed during the term of this Agreement except by written
      agreement of the Company and the Union.

(b)   Work Schedules

      (1)  *Work schedules for each work week will be posted on Thursday of the
           previous week prior to the end of the first shift. If an employee's
           work schedule is changed after the end of the first shift of the
           preceding Thursday, he shall be compensated by multiplying the
           regular straight time hourly wage rate by one-half (0.5) for the
           first eight (8) hours worked in his new schedule and the premium
           shall be paid in addition to whatever compensation the employee is
           otherwise entitled to receive under any other Section of the
           Agreement.

      (2)  If an employee's work schedule is not posted on Thursday of the
           previous week prior to the end of the first shift as provided above
           the first eight (8) hours worked the following week shall be
           considered out-of-schedule and will be paid accordingly. An
           employees work schedule is changed when the employee is required by
           a schedule posted after the first shift on the previous Thursday to
           work hours in place of the hours the employee was required to work
           by the schedule posted prior to the end of the first shift on the
           previous Thursday.

* See Attachment "B"

      (3)  If any employee's schedule is changed after the Thursday posting as
           a result of an employee who is absent from the plant not notifying
           the Company by 9:00 A.M. on the date of the posting that he will be
           available for work the following week, no schedule penalty shall be
           paid to the employees so affected including the employee returning
           to work.

           The above exemption from the scheduling clause penalty shall not
           apply to schedules changed as a result of an employee returning from
           vacation, a floating holiday, bereavement leave or jury duty.


16

<PAGE>   17


      (4)  If any employee's schedule is changed after the Thursday posting as
           a result of an employee exercising his "work option" under Article
           VI (e), no schedule penalty shall be paid to that employee
           (including the employee who exercises his "work option".

      (5)  The current practice of scheduling an employee so that the employee
           has two consecutive days off work under normal working conditions
           shall not be changed during the term of this Agreement except by
           written agreement of the Company and the Union.

      (6)  The Company will not permanently change the work schedule for a job
           during the term of this Agreement. If the Company decides that the
           work schedule for a job should be permanently changed, the Company
           will eliminate the old job and bid the new job. The status of any
           employee who is affected by this sub-paragraph (6) will be
           determined by the procedures outlined in Article V (b) except that
           the bumping procedure outlined in steps (1) through (4) of Article V
           (b) need not occur in order set forth, and further provided should
           the employee elect to bump under Article V (b) (4), he will be given
           a one week break-in if required.

      (7)  When the Company changes an employee's schedule, the Company will
           explain to the employee the reason for the change and the estimated
           duration of the change. The estimated duration of the change is
           provided the employee solely to assist the employee in personal
           planning and does not limit the Company's right to increase or
           decrease the duration of the change.

      (8)  See Appendix E for examples. See Appendix B for normal schedules.
           See Appendix D for those jobs normally filled.

(c)   Straight Time Work

      All hours worked and all hours paid shall be compensated by multiplying
      the regular straight-time hourly wage rate by one (1.O) unless expressly
      provided otherwise.

(d)   Rates of Pay - Overtime

      (1)  The applicable overtime rate shall be time and one-half (1.5) the
           employee's straight time hourly rate except on a Sunday or a
           holiday, in which case the applicable overtime rate shall be:

      1.   Up to 8 hours                                        3X

      (2)  Over eight (8) hours or over forty (40) hours: The Company agrees to
           pay for all times in excess of eight (8) hours per day, forty (40)
           hours per week, at the applicable overtime rate.

           If an employee does not work a regularly scheduled workday through
           action of the Company, excused absence or because of a holiday, that
           day shall be considered as actually a day worked for all overtime
           purposes.

      (3)  Callouts and off-days: In case an employee is called for emergency
           work during any hour in the day or week, in addition to his regular
           schedule, he shall receive a minimum of four (4) hours pay for such
           work, at the applicable overtime rate. However, if he is notified
           before the end of his regular shift to report early, it shall not be
           considered a callout. Callout hours and off-day hours are overtime
           hours. All Sunday callouts to be paid a minimum of four (4) hours at
           the applicable Sunday rate.

      (4)* In the event an employee works more than twelve (12) hours in the

           (12) twelve hours at double (2x) his regular straight time hourly
           rate.

(* See Attachment "B")


18
<PAGE>   19


           After an employee has been engaged in work for twelve (12)
           consecutive hours, he shall be paid for all consecutive hours worked
           immediately succeeding and in excess of such twelve (12) hours at
           double (2X) his regular straight time hourly rate. *If an employee
           is being paid the rate of double time under the foregoing
           paragraphs, his rate of pay shall not be reduced when his work
           continues into or overlaps his regular shift. However, the Company
           may exercise either of the following options:

A.    The Company may instruct the employee to continue to the end of the shift
      at the double time rate, or

B.    The Company may send the employee home at any time during the shift,
      provided the remainder of the shift is paid for at straight time. Such
      employee cannot be called back to work until he has been off duty for
      eight (8) consecutive hours.

      In no event shall the first two provisions of this section be applied to
      the same hours of work. The provision which creates the highest earnings
      shall be applied.

      (5)  Lunch period interrupted by work assignment: One-half (0.5) hour at
           applicable overtime rate shall be paid for any scheduled lunch
           period interrupted by a work assignment and either prior or
           subsequent to the regular lunch period, reasonable time for lunch
           shall be granted with pay for same at the employee's regular rate.

      (6)* Seventh consecutive day: If an employed actually works seven (7)
           consecutive workdays in the plant workweek regardless of the number
           of hours worked on any workday, the employee shall be compensated by
           multiplying the classified hourly wage rate by one (1.O) for each
           and every hour worked during the seventh consecutive workday, and
           this premium shall be paid in addition to whatever compensation the
           employee is otherwise entitled to receive under any other section of
           the Agreement.

      (7)  Overtime paid for on a daily basis shall not be duplicated on a
           weekly basis.

(e)   Limitations upon Overtime:

      (1)  Every reasonable effort will be made by the Company to avoid
           requesting any employee to work overtime and the Company will
           consider under the circumstances involved any reasonable excuse from
           an employee for not working the overtime. During the extended period
           of scheduled overtime, the Company will give special consideration
           to

* See Attachment "B"


19
<PAGE>   20

           an employee's request to be excused from overtime work because of
           fatigue as long as it is consistent with the Labor Agreement and
           plant operational requirements. Whenever an employee is on layoff
           due to lack of work or because of curtailment of operations no
           overtime work will be scheduled on any work which the laid-off
           employee is capable of doing and is able to perform, except in cases
           of emergency repair or unscheduled absences of other employees. The
           foregoing to the contrary notwithstanding a laid-off employee will
           not be called back to work unless; there is at least thirty-two (32)
           hours work in the work week for such employee.

      (2)  Overtime in the various job classifications shall be equally divided
           among the employees of the respective job classifications insofar as
           it is practical to do so. When an employee is not available for
           overtime in his classification, the Company will make every effort
           to use another qualified employee in the same department before
           going to another department. This will not prevent the Company from
           going outside the department where the overtime is required to avoid
           the payment of a rate whether penalty or premium of greater than
           time and one-half (1.5). The practice of posting overtime will be
           continued.

      (3)  After an employee is transferred or assigned to a classification
           other than his own, he shall be eligible for the same overtime
           within that classification as would the employee he replaced.

      (4)  Employees who are called upon to work overtime shall not be laid off
           during their regular work time for the purpose of equalizing said
           overtime.

      (5)  The Company will pay overtime in fifteen (15) minute increments
           during the first hour of overtime.

(f)   (1)  Any employee who has not been notified of his overtime assignment at
           least twelve (12) hours prior to the commencement of the overtime
           assignment and who works more than ten (10) consecutive hours, shall
           be provided with a hot lunch. This lunch shall be eaten at the end
           of the normally scheduled shift and before the commencement of the
           overtime assignment. The Company will allow the employee thirty (30)
           minutes away from his/her job to eat his/her lunch. If each employee
           works in excess of fourteen (14) consecutive hours he/she shall be
           provided with an additional lunch and thirty (30) minute break, and
           lunches and breaks will be furnished at the end of every four (4)
           consecutive hours worked thereafter. See Attachment "C".
           

20

<PAGE>   21


      (2)  Any employee who is called out and works more than four (4)
           consecutive hours shall be provided with a hot lunch which shall be
           eaten at the end of said four (4) consecutive hours. In addition,
           said employee shall be provided with a hot lunch every four (4)
           consecutive hours worked thereafter.

           There shall be no duplication of hot lunches under provisions (1)
           and (2) above. The employee shall be given reasonable time to eat
           his lunch without loss of pay.

(g)   Eight Consecutive Hours Off-Duty: *

      (1)  An employee should receive at least eight (8) consecutive hours off
           work within the fourteen (14) consecutive hours immediately
           preceding the start of his next scheduled shift. In the event an
           employee does not receive eight (8) consecutive hours off work
           within the fourteen (14) consecutive hours immediately preceding the
           start of his next scheduled shift, the Company shall exercise one of
           the following options:

A.    Instruct the employee to report late for his next scheduled shift by the
      number of hours his longest consecutive off-duty period falls below eight
      (8) hours and pay the employee the appropriate straight time rate for
      those hours not worked between the starting time of his scheduled shift
      and the time he reports to work in accordance with the Company's
      instructions. The appropriate straight time rate on the workday Sunday
      shall be one and one-half (1.5) and on a recognized holiday, two and
      one-half (2.5).

B.    Instruct the employee to report to work at the starting time of his
      scheduled shift. The employee shall receive a premium for those hours
      worked which, if added to his longest consecutive off-duty period, equal
      eight (8) hours. The premium shall be determined by multiplying the
      classified hourly wage rate by one (1.O). The premium shall be in
      addition to whatever compensation the employee is otherwise entitled to
      receive under any other section of this Article.

      (2)  If an employee does not receive at least eight (8) consecutive hours
           off work within the fourteen (14) consecutive hours immediately
           preceding the start of call-out hours worked on an off-day (provided
           that any of the call-out hours worked occur within the hours the
           employee would have otherwise been scheduled to work had the
           employee not been scheduled off), the employee shall receive a
           premium for those hours worked which, if added to his longest
           consecutive off-duty period, equals eight (8) hours. The premium
           shall be determined by multiplying the classified hourly wage rate
           by one (1.0). The premium shall be in addition to whatever
           compensation the employee is otherwise entitled to receive under any
           other Section of this Article.


21
<PAGE>   22


(h)   Sunday Work:

     All hours worked by an employee on Sunday which are not paid for on a
     premium and/or overtime basis shall be paid at the rate of one and
     one-half (1.5) times the classified hourly rate, exclusive of shift
     differentials. There shall be no duplication or pyramiding of premium day
     and/or overtime under this provision.

* See Attachment "B"

(i)   Temporary Job Vacancies:

      (1)  The Company shall not be required to fill temporary job vacancies,
           whether scheduled or unscheduled, unless the efficient operation of
           the plant requires that said temporary job vacancies be filled.

      (2)  Consistent with the scheduling clause, the Company will post a list
           of all jobs that are to be filled the following week.

           In addition, for the sole purpose of facilitating the assignment of
           fill-ins for the following week, the Company will post on Monday, a
           list of the jobs that, to its knowledge, will be needed to be filled
           the following week. If an employee wishes to be considered for any
           fill-in for the following week he must notify the Company which job
           he desires on a form provided by the Company by 4:00 P.M. the
           Wednesday after the Monday posting or he will not be considered for
           the fill-in. This Monday posting does not replace the Thursday
           posting requirements nor is the Company liable for any penalties for
           failure to make such Monday posting.

           Laborers who wish to be considered for these assignments must follow
           the above procedures. If there are not enough employees signed up to
           meet the Company's requirements on this posting, the Company will
           assign the junior laborer who is broken in on that job (if it is a
           job that requires break-in time).

      (3)  The Company can assign laborers to fill temporary vacancies,
           scheduled or unscheduled, according to the seniority of the
           individual provided that he has the skill and ability to perform the
           required work. If only one (1) laborer is qualified, he must accept
           the assignment. Once 

22

<PAGE>   23


           laborer assignments have been completed, no laborer may be bumped
           out of his assigned job, for the week for which the assignment has
           been made, by another laborer. Vacancies which are normally filled
           are outlined in Appendix D.

(j)   Wage Rate - Transfer and Assignments

      (1)  An employee regularly scheduled to work on two (2) or more jobs
           having different wage rates shall receive the highest rate of the
           entire week. If a job is regularly scheduled to be performed each
           week at least one work day in the work week, the employee filling
           that job shall receive the highest wage rate for the entire week. An
           employee who is scheduled to work five (5) work days during the work
           week on a job or jobs having a higher straight time hourly wage rate
           or wage rates than the employee's regular straight time hourly rate,
           shall be paid at the higher straight time hourly wage rate for the
           entire week. An employee who works on two or more jobs in one day
           shall receive the highest wage rate for only the time worked on the
           higher rated job. However, should the employee work on a higher
           rated job(s) for four (4) hours or more in the workday, he will
           receive the higher rate of pay for the entire day. The term "entire
           week" used in this section shall mean the 168 consecutive hours
           beginning at 7:00 A.M. on Sunday and ending at 7:00 A.M. on Sunday.
           The term "entire day" used in this section shall mean the 24
           consecutive hours beginning at 7:00 A.M. and ending the following
           day.

      (2)  Employees temporarily transferred shall be paid the classified
           hourly rate of the job being performed or the classified hourly rate
           of his regular job, whichever is greater.

(k)   (1)  The Company shall have the right to utilize employees to perform any
           job: provided, however, overtime and callouts in any classification
           shall be offered to the available employees in that classification
           before other employees are assigned such work. See Attachment "C"
           for Letter of Understanding concerning transfers.

      (2)  The Company will consider a request from a fixed shift employee to
           replace an employee on the day shift in his classification when the
           day shift employee is on vacation or extended illness in excess of
           one week provided however, that the laborer used to replace the
           offshift employee has been previously trained in that
           classification. The Company retains the right to decline these
           requests, but will not unreasonably withhold such permission.

(1)   Reporting Pay:

      Any employee who is required to report for work shall be given at least
      four (4) hours pay at the classified hourly rate, and shall receive full
      time pay for all time thereafter that he is required to remain on the
      premises ready for work. Any employee put to work on his regular working
      day shall receive a full day's pay at the classified hourly rate.

      The above does not apply to an employee who is returning to work from a
      medical absence who has not given the company 24 hours advance notice of
      his return.

(m)   Funeral Leave

      An employee upon the notification of the death of his or her father,
      mother, spouse, son, son-in-law, daughter, daughter-in-law, brother,
      sister, stepfather, stepmother, stepson, stepdaughter, grandson,
      granddaughter, half-sister, half-brother, mother-in-law, father-in-law,
      brother-in-law, sister-in-law, grandparents, and spouses grandparents
      shall be granted his or her next three (3) scheduled working days off
      with pay (four (4) days off with pay if the employee is required to
      travel beyond a radius of 500 miles).

      The foregoing to the contrary notwithstanding no bereavement payment will
      be made unless the employee attends the funeral nor will payment be made
      if there are more than fourteen calendar days between the date of death
      and the next scheduled workday .

      Payment by the Company for such time lost shall be on the basis of eight
      (8) hours per day at the employee's regular straight time hourly rate,
      including shift differential.

      As used herein, brother-in-law is defined to mean (1) the brother of
      one's husband or wife, (2) the husband of ones sister, (3) the husband of
      the sister of one's spouse: and sister-in-law is defined to mean (1) the
      sister of one's husband or wife, (2) the wife of one's brother, (3) the
      wife of the brother of one's spouse.

      The above clause shall not apply to an employee who is laid off, except
      that when an employee is notified to return to work on or before the date
      of the funeral, he shall be granted full funeral leave with pay. -

(n)   Jury Duty

      Any regular employee (as distinguished from a probationary employee)
      required to perform jury duty on a day he is scheduled to work, shall be
      excused from work on that day. The 


24
<PAGE>   25


      Company shall pay the employee the difference between the amount received
      from such jury duty and eight (8) hours at his regular rate of pay plus
      shift differential if involved.

      The day or days paid for such jury service shall be counted as eight (8)
      hours worked for the purpose of computing weekly overtime.

(o)   Shift Change

      (1)  The end of the shift whistles will be combined to one whistle,
           twenty (20) minutes before the end of the shift. This will allow
           ample time to put tools away and shower. As soon as employees' tools
           are put away, they may immediately proceed to the showers. Employees
           should stay on their job until this whistle blows.

      (2)  An employee who does receive a paid lunch period and whose job is
           set forth in the list below shall not clock out prior to the end of
           his shift. Providing he will not work past the end of his shift on
           an overtime assignment, he shall be permitted to leave his place of
           work 15 minutes prior to the end of the shift to enable him to clean
           up and change clothes. Should the employee elect to spend additional
           time in cleaning up following the actual end of the shift, he shall
           be paid as though he had clocked out at the actual shift change
           time.

           Any employee who works past the end of his shift on an overtime
           assignment, except in those cases where an employee is filling a
           vacancy, shall clock out no more than 15 minutes after he leaves his
           place of work. This 15 minute allowance shall not apply to an
           employee filling a vacancy on overtime, an employee staying over
           less than one hour nor to an employee on call out.

           Should the employee miss any part or all of his 15 minute wash up
           time, there is no penalty. However, if said employee is regularly
           denied his wash-up time, he may file a grievance in a timely manner.

      (3)  An employee not receiving a paid lunch period who works past the end
           of his shift on an overtime assignment shall clock out no more than
           fifteen (15) minutes after he leaves his place of work. This fifteen
           (15) minute allowance shall not apply to an employee staying over
           less than one (1) hour nor to an employee on call-out.

(p)   Rest Breaks

      (1)  An employee who does not receive a paid lunch period will be allowed
           a fifteen (15) minute rest break away from his job during the first
           four (4) hours of his shift. Break times shall be determined by the
           employees foremen, and 


25

<PAGE>   26


           the efficient operation of the plant shall be controlling. The
           fifteen (15) minute break shall be strictly construed to be the
           total time away from the job. Should any employee regularly be
           denied a break, he may file a grievance in a timely manner.

      (2)  Any employee who does receive a paid lunch period and whose job is
           set forth in the list below shall be entitled to 15 minutes away
           from his job to eat lunch. Lunch breaks for all employees in this
           group shall be scheduled so that there is no interruption of
           operations. (The Company shall have the right to stagger lunch
           breaks.) Should the employee miss any part of or all of this 15
           minute lunch break, there is no penalty. However, if said employee
           is regularly denied his lunch break, he may file a grievance in a
           timely manner.

(q)   If after the Thursday posting and prior to Sunday, it is determined that
      an employee is to be scheduled to work in another classification, he
      shall share overtime rights in that classification starting on Sunday.
      This sub paragraph (q) shall not void the requirement of Article VII (b).
      (The schedule change clause.)

(r)   The Company will not require an employee to clock out and then require
      him to clock back in for the sole purpose of avoiding penalties provided
      for in Article VII.

(s)   Any other provisions of this labor agreement to the contrary
      notwithstanding, no employee shall receive pay for any hour worked or
      unworked which singly or in any combination, exceeds triple his regular
      straight time hourly rate.

                                  ARTICLE VIII

                               VACATIONS WITH PAY

      following vacation eligibility schedule:

      (1)  All employees who have completed one (1) or more anniversary years
           of service, but less than three (3) years of service, will be
           entitled to two (2) weeks of vacation, provided they meet all other
           requirements of this Article. Employees who have completed three (3)
           or more anniversary years of service, but less than ten (10) years
           of service will be entitled to 


26

<PAGE>   27


           three (3) weeks of vacation, provided they meet all other
           requirements of this Article. Employees who have completed ten (10)
           or more anniversary years of service, but less than twenty (20)
           years of service, will be entitled to four (4) weeks of vacation,
           provided they meet all other requirements of this Article. Employees
           who have completed twenty (20) or more anniversary years of service,
           but less than thirty (30) years of service will be entitled to five
           (5) weeks of vacation, provided they meet all other requirements of
           this Article. Employees who have completed 30 or more anniversary
           years of service, but less than thirty-five (35) years of service,
           will be entitled to six (6) weeks of vacation, provided they meet
           all other requirements of this Article. Employees who have completed
           thirty-five (35) or more anniversary years of service will be
           entitled to seven (7) weeks of vacation, provided they meet all
           other requirements of this Article.

      (2)  Employees hired after May 1, 1996 shall be subject to the following
           vacation schedule:

      (1)  All employees who have completed one (1) or more anniversary years
           of service, but less than five (5) years of service, will be
           entitled to two (2) weeks of vacation, provided they meet all other
           requirements of this Article. Employees who have completed five (5)
           or more anniversary years of service, but less than fifteen (15)
           years of service will be entitled to three (3) weeks of vacation,
           provided they meet all other requirements of this Article. Employees
           who have completed fifteen (15) or more anniversary years of
           service, but less than twenty-five (25) years of service, will be
           entitled to four (4) weeks of vacation, provided they meet all other
           requirements of this Article. Employees who have completed
           twenty-five (25) or more anniversary years of service, will be
           entitled to five (5) weeks of vacation.

(c)   Vacation pay will be based on a forty (40) hour week at the rate of the
      permanently assigned classification on which an employee is working at
      the time he takes his vacation. If an employee has held a single higher
      rated classification for more than six (6) months during the year
      preceding his vacation, he will receive vacation pay computed at the
      higher rate. Vacation pay shall include appropriate shift differential
      for those on fixed shifts. Employees working on rotating shifts shall be
      paid an average of the rates for the rotating shifts involved. Upon
      sufficient notice given to the Personnel Clerk, the Company will give an
      employee his vacation pay on his last shift prior to the beginning of his
      vacation.

(d)   (1)  Vacations will not be cumulative, but so far as practical, be
           granted at times most desired by employees, but the final right to
           allotment of vacation periods is exclusively reserved to the Company
           in order to insure the orderly operation of the plant. In exercising


27

<PAGE>   28


           its right to allot vacation periods, the Company will not require
           any employee who is on layoff to take his vacation during periods of
           plant shutdown or curtailment of operation. Where requested vacation
           periods conflict, preference shall be given to the older employee in
           point of service.

      (2)  It is further agreed that if any employees have previously selected
           their vacation period so that it occurs during an unforeseen
           shut-down, such vacation period shall not be changed. Vacations
           shall be taken by the employee within the calendar year in which it
           is granted.

      (3)  The Company shall submit appropriate application blanks to the
           employees within the first week of November, and they are to be
           returned to the Company within one (1) month. In the event an
           employee fails to return this form to the Company, then, after this
           one (1) month period, the Company shall designate the employee's
           vacation period, and notify the employee who fails to return this
           application to the Company and the Union of the vacation period
           designated for the employee. All vacation blanks received from
           employees or issued by the Company shall be returned to the
           employees not later than January 1st.

(4)   (a)  An employee with four (4) or more weeks of vacation can take pay in
           lieu of vacation for a maximum of two (2) weeks of his total
           vacation eligibility. The above employee may request his payment at
           any time from January 1st till the date he turns in his application
           blank for his vacation selection. He will receive payment the next
           pay period following the date he makes the request.

      (b)  However, if the above employee does not request two weeks pay in
           lieu of time off, he may request up to two weeks pay in lieu of time
           off during the calendar year during periods of plant shutdown or
           curtailment of operations. Such payment will be made the next pay
           period following the date he makes such request.

      (c)  An employee with four or more weeks vacation, may change two of his
           scheduled weeks of vacation and reschedule them during a plant
           shutdown or production curtailment provided that the departmental
           vacation rules will allow him to be absent from the department.

      (5)  Any change in an employee's selected and designated vacation period
           must be approved by the Company and the Union committee, except as
           provided in (4) (b) and (c) above.

28

<PAGE>   29


      (6)  Employees entitled to two (2) or more weeks of vacation may be
           permitted to take such vacations in two (2) separate periods of not
           less than one (1) week each. seniority preference, however, can be
           exercised in only (1) of such vacation periods.

           In addition to the vacation general rules that are now in effect,
           the following procedure, which indicates how subparagraph (d) will
           be applied, shall be followed:

(e)   Step I

      The most senior employee in a department will be asked to choose his
      preference period which must be a period of one or more consecutive
      weeks. After the aforementioned weeks have been selected, each man in
      terms of descending seniority will be asked to select his preference
      period until all employees in the department have made their preference
      choice.

      Step II

      Next, the most senior employee in the department will again be asked to
      make a selection for those weeks remaining that have not been earmarked
      as a preference period. He will now have made a selection for all weeks
      for which he is eligible. After the aforementioned weeks have been
      selected, each man in terms of descending seniority will be asked to
      select his "other than preference" weeks until the least senior man had
      made his selection. The procedure for this department is now complete.

(f)   Employees who have one (1) or more years of service and who are separated
      from service for any reason will receive vacation pay due them on the
      following basis: One-twelfth (1/12) vacation credit for each one hundred
      (100) hours worked in his current calendar year.

(g)   In the event the employment of any such employee is terminated for any
      reason, the Company shall pay to the employee, or to his beneficiary in
      the event of his death, all vacation pay due.

(h)   If an employee enters military service and is not expected to return
      before the end of the calendar year, the Company shall pay to the
      employee, all vacation pay due.

(i)   Employees who wish to have a separate vacation check issued must give the
      Company two weeks notice and they will be only issued on payroll weeks.

(j)   An employee will be allowed to take one (1) week of vacation on a day to
      day basis for prearranged time off with at least seven (7) days prior
      notice. The Company will maintain the corresponding percentage of
      employees for vacation purposes at 14.5% plus two extra employees off
      during May, June, July, August and September. 


29

<PAGE>   30


      Vacation taken on a day to day basis, as noted in (j) above, shall not be
      included in the calculation in section (j) above, of the percentage of
      employees permitted off for vacation purposes.

      The final right of allotment of vacation periods is exclusively reserved
      to the Company in order to ensure the orderly operation of the plant.

                                   ARTICLE IX

                                    HOLIDAYS

(a)   New Year's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
      Veteran's Day, Thanksgiving Day, the first day of Pennsylvania Deer
      Season, the day before Christmas, Christmas Day and one floating holiday
      are recognized as "holidays".

(b)   If any such holiday falls on Sunday, the following Monday shall be the
      recognized holiday. The holiday hours shall be those hours within the 24
      hour period, commencing with the beginning of the first shift on the
      morning of the holiday and ending at the beginning of the first shift the
      following day.

(c)   If any holiday falls on Saturday, the preceding Friday shall be the
      recognized holiday.

(d)   Employees who are scheduled to work on a holiday shall be paid two and
      one half (2.5) times the classified hourly rate.

(e)   Hours worked on a holiday in excess of eight (8) in a work day, in excess
      of forty (40) in a work week, on off days, and on callouts shall be paid
      for at the applicable overtime rate.

(f)   If no work is required of an employee on the above holidays, he will
      receive eight (8) hours pay at his regular straight time rate, provided
      he meets the following qualifications:

      (1)  The employee shall have been employed by the Company for at least
           thirty (30) Calendar days prior to the holiday.

      (2)  The employee shall have worked his last scheduled working day prior
           to and his next scheduled working day after such holiday unless
           excused therefrom by the Plant Manager on account of sickness,
           accident, death in the family, or other excused absence. In no event
           shall a holiday be paid for unless an employee has also worked
           during the thirty (30) day period immediately preceding or
           immediately following the holiday except that the thirty (30) day
           limitation shall not apply if the employee was temporarily absent
           from work because of sickness, accident, or layoff. In any event,
           the employee must work at least one (1) day in the calendar year in
           which the holiday is granted.


30

<PAGE>   31


(g)   If an employee is scheduled to work on a holiday and fails to work, he
      shall not receive holiday pay.

(h)   If an employee works on a holiday, the holiday shall be counted as a day
      worked for computing his weekly overtime. Paid holiday is to count as day
      worked for overtime purposes, provided holiday falls on one of employee's
      scheduled work days and he would have worked that day except for holiday
      observance.

(i)   An employee not scheduled to work the holiday and who subsequently
      performs work on a holiday will be considered as being on callout and
      will be paid eight (8) hours at his regular straight time hourly rate in
      addition to three (3) times his regular straight time hourly rate for all
      time worked with a minimum of four (4) hours at triple time.

(j)   Work schedules for each work week which include a holiday will be posted
      prior to the end of the first shift on Thursday of the previous week. If
      an employee is scheduled to work on a holiday, but then is instructed by
      the Company not to work he shall receive for that holiday eight (8) hours
      pay at two and one-half (2.5) times his regular straight time hourly
      rate.

(k)   The phrase "straight time hourly wage rate" as used solely in Article IX,
      Holidays, shall mean the higher of either the employee's regular straight
      time hourly wage rate or the highest straight time hourly wage rate for a
      job on which the employee works at least eight (8) consecutive hours in
      the work week in which the holiday falls provided (1) that the eight (8)
      hours had been previously scheduled or (2) the hours are worked the day
      before or the day after the holiday whether previously scheduled or not.

(l)   In any week in which a schedule or floating holiday falls while an
      employee is on layoff and he does not receive a S.U.B. benefit solely
      because funds are not available, such employee shall be paid for the
      holiday provided he worked his last scheduled work day before the holiday
      unless excused from working such day under Article IX (f) (2). Such
      payment will be paid with the next paid period immediately following the
      holiday.

      Should the employee receiving the above payment subsequently terminate or
      be terminated for any reason prior to his recall from that layoff, the
      amount of holiday pay received under this section shall be deducted from
      any monies due him from the Company .

(m)   The Company will consider the request by an employee to take his
      "floating holiday" the day before or the day after a scheduled holiday.
      This request must be designated when the employee turns in his annual
      vacation request. The efficient 


31

<PAGE>   32


      operation of the plant and its departments will be the first
      consideration and the Company reserves the right to decline any
      individual request. If there is a scheduling conflict between two or more
      employees, when the Company grants a request which those employee have
      made for the same floating holiday, seniority will govern.

                                   ARTICLE X

                                     WAGES

(a)   Considered a part of this Agreement but contained as a separate manual
      are the Job Description and Job Classification sheets for all permanent
      jobs in the plant, and the administrative procedures governing the
      Cooperative Wage Study Program. Any new job to be evaluated or an
      existing job to be re-evaluated should be done within ninety (90) days
      whenever possible. Any changes in rates shall be retroactive to the date
      the Committee requests the Plant Manager to evaluate or re-evaluate the
      job. The current Job Classification and Rate List is attached as Appendix
      A.

      When a job requested to be reevaluated by the evaluation process the
      Local will submit the Job Evaluation Request form IR-74-2. The form is
      provided to allow for a reasonable amount of information explaining the
      justification for the job evaluation request. The Company will meet with
      the Committee to discuss the merits of a new job or additional duties of
      present jobs. Weigh the factors and try to come to a mutual agreement on
      the rate. If we can't agree, the grievance procedure can be used. The
      Company is willing to meet to evaluate a job within 90 days of changes.
      Agreed upon changes will be retroactive to the date on the Form IR-74-2.

(b)   (1)  Scheduled shift workers on the first shift shall receive the
           classified hourly rate.

      (2)  Scheduled shift workers on the second shift shall receive the
           regular straight time hourly rate plus 47 cents per hour.

      (3)  Scheduled shift workers on the third shift shall receive the regular
           straight time hourly rate plus 70 cents per hour.

      (4)  These premium rates do not apply to day workers even though they may
           work over into premium paid shifts.

      (5)  If a day worker is scheduled to take the place of a regular
           scheduled shift worker then the premium rate for the shift shall
           apply.

      (6)  The premium pay does not alter the provisions covered in Article
           VII, Working Conditions.

      (7)  Shift differentials shall be included as part of the regular rate in
           the calculation of overtime compensation.

(c)   When changing from standard to daylight time, those employees on the 11-7
      shift scheduled for seven (7) hours and actually working seven (7) hours

      individual in any class without necessitating a change in the rate of any
      individual or class.

                                   ARTICLE XI

                                BULLETIN BOARDS

      The Company agrees to allow the proper officers of the Union who are
      employees of the Wampum Plant of the Company to use one designated
      section of the plant bulletin board for posting notices in the interest
      of the Company and its employees.

                                  ARTICLE XII

                             HANDLING OF COMPLAINTS

(a)   All employees shall at all times make an effort to perform their duties
      in such a manner as to promote safe and efficient operation of their
      department and the plant as a whole.

      (l)  Should a difference arise between an employee and the Company as to
           the meaning and application of this Agreement, or should a
           difference arise as to the meaning and application of a recognized
           practice, the employee with or without his steward shall present his
           complaint to his foreman within ten (10) working days after the date
           of the alleged wrong or within ten (10) days (the grievant's
           scheduled work days) after the date the employee received his
           payroll check, whichever is later.

      (2)  The foreman shall orally reply to the employee within five (5)
           working days after the date the employee presented his complaint in
           Section (1).

      (3)  If the employee is not satisfied with the foreman's reply, the
           employee may request his steward to present the grievance in writing
           to the Union Grievance Committee. If the Union Grievance Committee
           believes that the complaint is justified, it may submit the
           complaint in writing to the Plant Manager within five (5) working
           days of the date of the foreman's reply in section (2). Within five
           (5) working days of the date the Union Grievance Committee submitted
           the complaint to the Plant Manager, he shall schedule a meeting with
           the Union Grievance Committee and 


33
<PAGE>   34


           any member or members of his staff that he desires to have present.
           This meeting will take place within fourteen (14) working days of
           the date the meeting was scheduled.

      (4)  The parties shall use their best efforts to settle the complaint. If
           the parties agree upon the disposition of the grievance, they shall
           reduce their understanding to writing and the grievance shall be
           settled. If the parties are unable to agree, the Union Grievance
           Committee may at the employee's request and within thirty (30) days
           of the date of the meeting between the Plant Manager and the Union
           Grievance Committee submit the grievance in writing to the Director
           of Industrial Relations or his representative with copies to the
           International Vice President or District Council Representative and
           the Plant Manager. Once ten (10) grievances have been submitted to
           the third step, the Director of Industrial Relations shall contact
           the International Vice-President or District Council Representative
           to schedule a meeting. The parties shall use their best efforts to
           schedule the meeting within thirty (30) days.

      (5)  After full consideration, and such conferences as may be mutually
           agreed upon with an International or District Council Representative
           of the Union, the grievance shall be considered settled when the
           employees representative and the Company's representative shall have
           reached an agreement.

      (6)  If the parties are unable to settle the grievance, either party can
           notify the other party in writing that it intends to submit the
           grievance to arbitration. This notice must be given within ten (10)
           working days of the receipt of written confirmation of verbal
           answers given at the last meeting in Section (5). The consent of the
           other party is not required to arbitrate a grievance.

(b)   When an issue is referred to arbitration, the parties shall select an
      arbitrator by mutual agreement within ten (10) days. Failing to reach an
      agreement upon the selection of an arbitrator, the parties shall request
      the appointment of an arbitrator by the Federal Mediation and
      Conciliation Service.

      After receipt of the list of a panel of arbitrators, acceptable to the
      parties, from the Federal Mediation and Conciliation Service, the
      grievances to be presented to the arbitrator selected must be heard by
      that arbitrator within six (6) months of the receipt of the panel.

      Grievances heard by the arbitrator must be presented in chronological
      order based on the date the grievances were written except in discharge
      cases which may be presented out-of-chronological order or in cases where
      the parties have mutually agreed in writing to waive the chronological
      order requirement.


34
<PAGE>   35


      If the arbitrator should cancel or postpone a hearing date after it has
      been agreed to by the parties, the time necessary to obtain a new date
      shall not be included in the six month time limit mentioned above.

      The six month time limit may be waived with the mutual consent of the
      parties.

(c)   All time limits set forth in (a) and (b) shall be strictly observed: time
      limits can be extended by a written agreement between the parties.
      Failure to observe any time limit shall cause the grievance to be
      considered settled in favor of the employee if the Company has failed to
      observe the time limit or in favor of the Company if the employee and/or
      the Union has failed to observe the time limit. Any grievance considered
      settled under conditions of this paragraph (c) shall be without
      precedent.

(d)   The arbitrator shall consider only the grievance appealed to him and
      shall have jurisdiction and authority only to interpret, apply, or
      determine compliance with the provisions of this Agreement and only to
      the extent necessary to determine the grievance. The arbitrator shall not
      have jurisdiction or authority to add to, modify, detract from or alter
      in any way the provisions of this Agreement,

(e)   The arbitrator's decision shall, at the request of either party, be in
      writing and shall be final and binding on both parties. The fees and
      expenses of the arbitration proceedings, except fees for witnesses
      brought in by either party and legal counsel's fees, shall be borne
      equally by the Company and the Union. Bargaining unit employees including
      Committeemen who participate in arbitration proceedings shall not be
      compensated by the Company,

(f)   Grievances involving the provision of the collective bargaining agreement
      and occurring so as to be processed to arbitration at the same time will
      be at the request of either party arbitrated before the same arbitrator.
      However, it is agreed that not more than four (4) cases will be heard at
      one (1) series of hearings.

(g)   Local Union officers and stewards off duty and representatives of the
      International Union and District Council shall, upon notice to the
      Company, be permitted on the Company's premises to investigate
      grievances.

(h)   Meetings will be conveniently scheduled so as to complete all business
      within the normal working day for day employees. Any employee who is
      scheduled to work during the hours the meeting is held and who attends
      the meeting will be compensated by 


35
<PAGE>   36


      multiplying his regular classified hourly wage rate by the hours he
      attends the meeting. In addition, if this employee attends the meeting
      beyond his normal quitting time, he will be compensated for each
      additional hour he attends the meeting by multiplying his regular
      classified hourly wage rate by one (1.0) and said additional hour or
      hours shall not count toward daily or weekly overtime.

      Any member of the Committee who is not scheduled to work during the hours
      the meeting is held, who is not scheduled to work the third shift
      immediately preceding the meeting, or who is not scheduled to work the
      second shift immediately following the meetings, and who attends the
      meeting, will be compensated by multiplying his regular straight time
      (1X) hourly wage rate by all hours he attends the meeting. Any hours paid
      under this paragraph shall not count toward the calculation of any
      penalty or premium pay section of this Agreement including but not
      limited to daily or weekly overtime. Any employee who is receiving S.U.B.
      benefit, sickness and accident benefits, or Workmen's Compensation
      Benefits for the day of the meeting or who is absent due to disciplinary
      layoff shall not receive any compensation under this paragraph.

      When a meeting is scheduled at which a representative of the
      International Union and a representative of the Company from Cleveland
      will attend, any member of the Committee who is scheduled to work the
      third shift immediately preceding the meeting will be excused from
      working the third shift and will be compensated by multiplying eight (8)
      hours at his regular classified hourly wage rate plus shift differential
      if the employee has attended the meeting .

      Any member of the committee who is scheduled to work the second shift
      immediately following the meeting will be excused from working the second
      shift if the employee has attended the meeting for six (6) hours. In the
      event the employee is excused from working the second shift, he will be
      compensated by multiplying eight (8) hours at his regular classified
      hourly wage rate plus shift differential.

(i)   Where there is a discussion between an hourly employee and a supervisor
      that is intended as a disciplinary measure, the Company requests that a
      grievance Committeeman, job steward or other designated employee be
      present.

      A "disciplinary measure" shall be limited to the issuing of a reprimand
      or the imposition of a penalty to an employee about which a notation,
      letter or unsatisfactory performance report is subsequently made part of
      the employee's personnel file.

      It shall be the responsibility of the Union to appoint and have available
      on each shift a committeeman, job steward or other employee designated
      for purposes of this Section who shall be identified to the Corporation
      in writing.


36
<PAGE>   37


      All written notations or reprimands that an employee receives can only be
      used for the twelve month period following the issuance of the notice in
      any future disciplinary actions.

      It is not the intent of this Section to expand the total number of
      committeemen as provided for in Article II (f).

                                  ARTICLE XIII

                              STRIKES AND LOCKOUTS

(a)   Having provided an orderly procedure for settling all disputes, the
      Company agrees not to lock-out its employees and the Union agrees that
      there will be no strikes or work stoppages during the term of this
      Agreement.

(b)   The Company agrees not to hold the Union liable when such activities are
      not authorized by the Union, provided that the Union, within forty-eight
      (48) hours, orders its members to cease and desist from such activities.

(c)   It shall not be a violation of this Agreement or cause for disciplinary
      action, including discharges if an employee refuses to cross a picket
      line that has been established in full compliance with existing laws.
      Picket lines established as a result of jurisdictional disputes, picket
      lines established for the purpose of organizing in-plant non-bargaining
      unit personnel, and/or informational picket lines are excluded from this
      protection.

      Notwithstanding the above, employees will not honor any picket line
      unless authorized by the International Union. The International Union
      will not be held liable for any subsequent damage to the Corporation
      resulting from refusal of employees' to cross an unauthorized picket
      line.

                                  ARTICLE XIV

      with heat, light, and plenty of hot water, and keep the toilets,
      fixtures, and floors in a sanitary condition, and will supply good
      drinking water wherever necessary about the plant. Sufficient equipment

      request of the injured, and the approval of the Plant Manager, and
      Director of Industrial Relations, other medical aid may be called in at
      the expense of the Company for consultation or treatment of any cases. It
      is agreed that a complete medical examination may be required before an
      applicant is employed. Also, that complete medical examination of any
      employee may be made annually or any time at the discretion of the
      Company. Copies of such reports and examinations will be kept on file by

      Another safety tour not exceeding two (2) hours will be granted to
      inspect the Quarry. The safety tour will have the sole purpose of
      inspecting the plant and identifying existing and potential safety and
      health hazards. The tours are to be conducted once per month, both of
      them prior to a plant safety meeting .

(d)   A Joint Safety and Health Committee shall be established Consisting of
      four (4) members, two (2) appointed by the Company and two (2) appointed
      by the Local Union. In the event that a member is absent from a meeting
      of the Committee, his alternate may attend and when in attendance shall
      exercise the duties of the member. The Plant Manager or his designee will
      be the fifth member and act as Chairman of the Committee.

      The Joint Committee shall meet as often as necessary, but no less than
      once each month, at a regularly scheduled time and place, for the purpose
      of jointly considering, inspecting, investigating and reviewing health

      health may request an immediate review of his job by the Joint Safety and
      Health Committee.

      No employee shall be disciplined or discharged for refusing to work on a
      job if his refusal is based on bona fide claim that said job is not safe

           premium shall be paid in addition to whatever compensation the
           employee is otherwise entitled to receive under any other section of
           this Agreement. If the parties disagree as to whether or not the
           work in question warrants the premium payment it shall be taken up
           by the Safety Committee. Employees will not be required to work in
           coolers and/or other equipment until such equipment has been

      work covered by Paragraphs (a or (b) above if it will directly result in
      the, 1. laving off of (or failure to recall) bargaining unit employees,
      or 2. the reduction of hours of bargaining unit employees below 40 hours
      a week; or 3. reduction of employees to a lower rated classification.

(d)   Further (a), (b) and (c) above does not apply to new construction or to
      construction involved in major modification work.

(e)   The Company agrees to notify the Local Union in writing with a copy to
      the International or District Representative who services the Local
      Union, sent by registered mail, at least fourteen (14) days in advance if
      reasonably possible, and to meet with the Union, upon request by the
      Union, for explanation of the reasons causing the Company to decide to
      contract any production and maintenance work. The parties agree that
      while notification is an important part of the working relationship
      between the parties and should be adhered to in order to reduce the
      number of disputes concerning sub-contracting the parties also recognize
      and agree that this Section of the Contract does not require any penalty
      when the Company fails to give proper written notice of its intention to
      sub-contract.

                                 ARTICLE XVIII

                                 WORK PRACTICES

The Company will provide training for one laborer when manning requirements of
the plant provide ample resources to man required operational jobs.

(a)   The following rules shall govern the training of laborers for the purpose
      of filling vacancies.

      (1)  Management will, one week in advance, announce and post the job for
           which training will be provided.

      (2)  Laborers must notify the Company, starting with the senior laborer,
           of their intent to accept the training in 1 above. If no one
           applies, the junior laborer may be required to train.

      (3)  Management will determine the number of laborers who will be trained
           for each classification.

      (4)  Management will determine the classifications for which laborers
           will be trained for the purposes of filling vacancies.

           a. Management will attempt to balance the number of jobs the
              laborers are to be trained in.

      (5)  The Company shall, before offering training in any job higher than
           bracket nine (9), to a laborer hired after 10/1/77, give the
           laborers hired prior to 10/1/77 the opportunity to train for a job
           higher than bracket nine (9) subject to the following conditions:

           a. The opportunity must be offered in order of seniority.

           b. The laborer shall have the choice of accepting or rejecting the
              training.

      (6)  During the time when temporary summer laborers are working at the
           plant, the following rules shall apply when training is offered to
           the Labor Department for the purpose of filling vacancies:

           a. Permanent laborers must accept training for purposes of filling
              vacancies. They shall be selected by canvassing the labor crew in
              order of seniority.

              If no permanent laborers voluntarily accept the training, the
              least senior one is compelled to do so.

           b. Temporary summer laborers can be used to fill vacancies as long
              as all permanent laborers are already working in that capacity.

      (7)  During the transition period before an additional packing crew is
           put on or taken off, it is recognized that a reasonable amount of
           overtime will be required. The Company will secure as much
           information from sales as possible so that this overtime can be held
           to a minimum and the addition of or removal of a shift is consistent
           with a continuing increase or decrease in package business.

      (8)  It is understood and agreed to by the Local Union No. 173 and the
           Local Management at the Medusa Wampum Plant that the amount of
           overtime that an employee has been charged is not a factor that
           Management must consider when it is making a choice as to who will
           be scheduled to work on a holiday or premium hours other than
           overtime hours.

           This means that the equalization of overtime is not a controlling
           factor over, and has no connection with, which employee is asked to
           work hours that are to be paid for at a premium rate. Contractual
           distribution of overtime requirements will be followed in all
           overtime cases.

      (9)  Production Utility shall be considered a classified employee for
           overtime purposes on the day he fills each classification. Once one
           of these classifications is exhausted on any other day, than those
           where he fills in, he would be eligible for overtime before going
           into the department.

      (10) If an employee's job requires a drivers license and he loses said
           license, said employee shall return to the laborer crew at labor
           rate with all rights and privileges of a Laborer.

      (11) The Company will maintain all Plant restrooms in a clean and orderly
           condition. This work will be assigned to a Mill Janitor and/or
           Laborer as required.

                                 MISCELLANEOUS

(a)   The Company will enter into a Union label agreement for the Company's
      package products.

(b)   Any hand tool that the employee uses in the performance of his job duties
      will be replaced in the event that the tool is rendered not usable during
      the course of the employee's work. The tool must be presented to the
      Company prior to replacement.

(c)   The normal time for distribution of pay checks to all employees shall
      begin with the start of the day shift every other Friday, except that
      Quarry employees and any employee starting the second shift will receive
      his pay check on the Thursday preceding the normal pay day.

(d)   Gloves will be made available for purchases to employees at cost on a
      cash basis.

(e)   When the Company decides that an interview between the Company and an
      employee regarding job qualification is to be conducted, a Committeeman
      chosen by the Company will attend the interview for the purpose of
      affirming that said interviews are conducted with a reasonable degree of
      uniformity.

(f)   Printing of Agreement - The Basic, Supplemental, Pension, S.U.B. and
      Insurance Agreements will be printed at Company expense and each copy
      will bear the Union label. The Company will provide each local with a
      supply of the booklets.

                                   ARTICLE XX

                               TERM OF AGREEMENT

(a)   This Agreement shall be binding upon the parties hereto, their
      successors, administrators, executors and assigns. In the event of the
      sale or lease by the Company of the Wampum Plant, or in the event the
      Company is taken over by sale, lease, assignment, receivership, or
      bankruptcy proceedings, such operation shall continue to be subject to
      the terms and conditions of this Agreement for the life thereof. The
      Company shall give notice of the existence of this Agreement to any
      purchaser, lessee, or assignee of said plant. Such notice shall be in
      writing with a copy to the Union not later than the effective date of the
      sale.

(b)   After ratification by the members of the Local Union, this Agreement
      shall become effective and remain in full force and effect and be binding
      upon the parties hereto from May 1, 1996 to and including April 30, 1999,
      and it shall continue in full force and effect thereafter from year to
      year until either party on or before March 1st, of any year, beginning
      March 1, 1999, gives written notice to the other party of its desire or
      intention

      either to alter or modify or to terminate the same. If such notice is
      given, the parties hereto shall begin negotiations not later than March
      31st in such year and this Agreement shall continue in full force and
      effect until completion and signing of a new Agreement, provided,
      however, that after such negotiations have continued without reaching an
      agreement until May 1st, in any year, then either party may terminate
      this Agreement, at any time thereafter upon notice.

(c)   The written notices set forth above by either party shall contain any
      changes or amendments desired, and only such changes or amendments as are
      contained in the two (2) written notices shall be discussed by the
      conferees,

(d)   The proposals and counter proposals made by each party shall not be used,

                                   APPENDIX D

                              JOBS NORMALLY FILLED


(a)   Providing the Company determines that sufficient work is available, it
      will normally fill the following jobs on a daily and weekly basis:

Janitor                             Utility Chemist
Unloading Attendant                 Production Utility
Storekeeper                         Quarry Specialist

Physical Chemist                    Rotating Repairman A
Pack & Loader                       Control Room Operator
Equipment Operator

(b)   The balance of the classifications are filled as circumstances require
      and as necessary to maintain the efficient operation of the Plant.


                                   APPENDIX E

                        EXAMPLES OF WORK SCHEDULE CLAUSE

The new work schedule clause is a significant change from the past practices at
the Wampum Plant. The new work schedule clause gives the Company the right to
change an employee's work schedule any time. If the change is made no later
than the end of the first shift on Thursday for the following week there is no
premium. If the work schedule change is made after the first shift on Thursday
for the following week, there is a premium.

EXAMPLE An employee normally works Monday through Friday from 7:00 a.m. to 3:00
p.m. Prior to the end of the first shift on Thursday, the employee is notified
that he will work Tuesday through Saturday from 3:00 p.m. to 11:00 p.m. the
following week. All hours the following week are paid at straight time. There
is no schedule change premium.

EXAMPLE Instead of being notified before the end of the first shift on
Thursday, the employee is told on Sunday that he will work Tuesday through
Saturday from 3:00 p.m. to 11:00 p.m. The eight hours worked on Tuesday are
paid at time and one half (1.5), the additional one-half time representing the
schedule change premium. All other hours worked during the week (Wednesday
through Saturday) are paid at straight time.

EXAMPLE An employee is scheduled to work Monday through Friday from 3:00 p.m.
to 11:00 p.m. On Tuesday, the employee is told that he will work from 3:00 p.m.
to 3:00 a.m. on Wednesday. This is not a schedule change. He is paid on
Wednesday as follows: First eight hours ace paid at straight time and the last
four hours are paid at time and one-half, the additional one-half tine
representing hours worked in excess of eight hours in the workday. A schedule
change takes place only when an employee is directed to work new hours in place
of, but not in addition to, his old hours.

This letter sets forth examples which illustrate various applications of the
work schedule clause as it will be applied at Wampum.

Those examples involving the filling of a vacancy assume the Company has
determined that sufficient work is available and that the vacancy must be
filled.

                                    Examples

1.    Situation

      Packhouse Pumpman quits Monday 6:00 p.m. How do we fill this example?

      Options

      Do not fill on Monday night, overtime in the classification is used on
      Tuesday, Laborer with schedule change premium on Wednesday, and same
      Laborer with straight time Thursday and Friday.

2.    Situation

      During the hot summer months, Repairmen are going to be required on the
      No. 1 Kiln Discharge Pier for two (2) weeks, and working conditions will
      be poor.

      Options

      Change 4 - Repairman "A" on 8:00 a.m. - 4:30 p.m. to 6:00 a.m. to 2:30
      p.m. No work schedule change premium when change posted on Thursday.

3.    Situation

      Front-End Loader is loading stone on first two shifts and bucket needs
      extensive welding for five (5) days.

      Options

      Change the schedule of two (2) 8:00 a.m. to 4:30 p.m. Repairmen to work
      Monday through Friday 11:30 p.m. to 8:00 a.m. No work schedule change
      premium when change is posted on Thursday.



55

<PAGE>   56


4.    Situation

      Must resurface road from tipple to plant and work will be done on day
      shift only but road will be passable on second and third shift.

      Options

      Schedule all people involved from Stone Shovel to Unloader "B" from an
      8:00 a.m. - 4:00 p.m. schedule to midnight to 8:00 a.m. No work schedule
      change premium is involved when the change is posted on Thursday.

5.    Situation

      On Wednesday during the middle of a bumping chain, we realize that the
      bumping will not be completed so that all moves can be made at the start
      of the week.

      Options

      The chain is stopped - creating a vacancy in the Operating Utility's
      classification. The Thursday posting will show a Laborer filling in the
      Operating Utility's job during the following week. No work schedule
      change premium is involved.

6.    Situation

      Have (4) Regrind Millers working a rotating 20 shift Sunday through
      Saturday schedule. During the months of December through April, Type III
      Shipments require 15 shifts of regrind operation.

      Options

      Curtail a Regrind Millers job for four (4) months and require three (3)
      Regrind Millers to work a rotating fifteen (15) shift schedule. At the
      end of four (4) months, revert to the rotating twenty (20) shift
      schedule. No work change premium.

7.    Situation

      Rod mill needs relining and job is to start Tuesday morning and worked on
      around the clock. How to schedule men?

      Options

      Schedule three (3) 4:00 p.m. - 12:30 a.m. Repairmen to 11:30 p.m. - 8:00
      a.m. on Tuesday, Wednesday and Thursday and back on their regular
      schedule on Friday. Pay would be Tuesday - schedule change premium;
      Wednesday, Thursday, Friday would be at straight tine.


56

<PAGE>   57


8.    Situation

      Duplication of above, but the job runs over one (1) extra day and the
      Repairmen must work 11:30 p.m. to 8:00 a.m. on Friday, also.

      Options

      Pay for Friday would be at schedule change premium because this would be
      second change in same week.

9.    Situation

      Emergency brick job on Thursday and Friday and job is worked around the
      clock.

      Options

      Schedule four (4) Repairmen to work 11:30p.m. - 8:00 a.m. Thursday and
      Friday. Pay on Thursday would be at schedule change premium and Friday at
      straight tine.

10.   Situation

      Repairmen who works 8:00 a.m. - 4:30 p.m. Monday through Friday requests
      Monday off for doctors appointment and all Repairmen are needed that
      week.

      Options

      Thursday posting would change said Repairman's schedule to Tuesday
      through Saturday and a Tuesday through Saturday Repairman to Monday
      through Friday. No schedule change premium applies.

11.   Situation

      Newly awarded Dozer Operator need to be trained on job. His schedule is:

          S         M        T        W        T        F        S
        11-7      11-7     11-7     11-7     11-7      OFF      OFF

      Company wants other Dozer Operator to train new man and trainees schedule
      is:

          S       M       T        W        T        F        S
         7-3     OFF     OFF      3-11     3-11     3-11     3-11

57

<PAGE>   58


      Options

      On Thursday posting, move new man to trainers schedule and qualified
      laborer to new man's schedule. No schedule change premium applies.

12.   Situation

      Will the Company schedule the same 8:00 a.m. to 4:30 p.m. Repairmen to
      work 11:30 p.p. to 8:00 a.m. every other week solely to provide permanent
      routine repair coverage at night, and call the change temporary rather
      than permanent?

      Options

      No.

13.   Situation

      Will the Company post a schedule on Thursday which schedules a Pumpman to
      work Monday through Friday from 8:00 a.m. to 4:30 p.m. and subsequent to
      posting, tell the Pumpman that his schedule is Monday, Wednesdays,
      Thursday and Friday? No day it substituted for Tuesday. The Pumpman is
      scheduled and works thirty-two (32) hours at straight tine.

      Options

      The Company does not intend to use the work schedule clause in the manner
      describe above.

14.   Situation

      The Company plans to reschedule an employee to work hours other than his
      normal hours the following week. The employee has made personal plans
      that will conflict with the hours the Company plans to reschedule the
      employee and which, if canceled, would work a hardship on the employee.
      There is another employee qualified to perform the same work. The
      employee asks the Company to reschedule the other employee rather than
      him explaining to the Company the conflict with his personal plans. The
      change front one employee to another employee will not cause the Company
      to incur any penalty or premium. Will the Company make every effort to
      comply with the employees request?

      Options

      Yes.


58
<PAGE>   59


15.   Situation

      The Company determines that around-the-clock repair work on the kiln is
      necessary. The Company estimates that tile work will take four (4) weeks
      and some first (1st) shift Repairmen and some second (2nd) shift
      Repairmen will be scheduled to work the third (3rd) shift to provide
      around-the-clock coverage during the kiln repair. Will the Company rotate
      repairmen to perform the required work so that the same repairmen are not
      rescheduled for all four weeks?

      Options

      The Company is willing to rotate Repairmen into the schedule required for
      the above work provided sufficient qualified men are available.

16.   Situation

      An employee is scheduled to work Monday through Friday from 3:00 p.m. to
      11:00 p.m. On Tuesday, the employee is told that he will work from 3:00
      p.m. to 3:00 a.m. on Wednesday.

      Options

      This is not a schedule change. He is paid on Wednesday as follows: First
      eight (8) hours are paid at straight time and the last four (4) hours are
      paid at time and one-half, the additional one-half time representing
      hours worked in excess of eight (8) hours in the work day. A schedule
      change takes place only when an employee is directed to work new hours in
      place of, but not in addition to his old hours.

The above examples are not all inclusive of every occasion when schedules may
be changed.

In addition, the method of filling vacancies in the examples are not intended
to imply that these are the only methods of filling vacancies or that the
option used in a particular example is the method the Company is required to
use.

                                   APPENDIX F

                          EXAMPLES OF PROMOTION CLAUSE

Interpretation of Article VI(a): If there are no applicants or if there are no
applicants qualified to perform the work, the Company at its option (1) can
hire a new employee who is qualified to perform the work for the vacant or new
job, or (2) can award the job to the laborer with the least seniority and train
the labors except that in the case of any vacant or new job that requires
nominal on-the-job training (jobs other than skilled jobs), the company intends
to award the job to an applicant rather than hire a new employee. This
statement of intent shall not limit the Company's right to disqualify the
employee if the employee fails to perform all of the duties of the job within a
reasonable period of time.

Interpretation of Article VI (d): John Smith bids for and is awarded on January
2, 1975 a Packer's job that normally is scheduled to work 12:00 noon to 8:30
p.m. Monday through Friday.

The Packer's job that normally is scheduled to work 7:00 a.m. to 3:30 p.m.
Monday through Friday becomes vacant and is posted for bids on April 15, 1975.

John Smith can bid on this job if his sole reason for bidding is to work hours
that normally ace different.

Another example of Article VI (d): The Company will consent to bidding from a
job that normally is a rotating shift job to the same job that normally is a
fixed shift job if the sole reason is to work hours that are normally
different.

                                   APPENDIX G

              PANEL DECISIONS - MAY 14 AND 15, 1974 PANEL MEETING

TO:       R.L. Everhart
          P.H. Geis
          B. Eversole, President Local No. 173
          A. Harris, Jr., Recording Sec'y Local No. 173

FROM:     A. Clavier, Jr.
          W.M. Troutman

GRIEVANCE #7

   Facts - The Company posted second shift laborer jobs to perform winter
maintenance. On the bids it stated that the jobs were required for only the
extent of the winter maintenance and upon completion of the program, the jobs
would be eliminated, there would be no 95% rate protection and the incumbents
would have bumping rights. Upon completion of the work, the employees were
directed to return to day shift laborer jobs or other jobs which they bumped
to.

   Issue - Did the Company violate the contract by not posting a notice in
advance of the elimination and are the employees entitled to out-of-schedule
pay for the time worked after the jobs were eliminated?

   Decision - The panel determined that each employee understood when he was
awarded the second shift laborer job that his job would be terminated when the
winter maintenance program was completed. Under these circumstances, written
notice is not required by the labor agreement. The grievance, therefore, is
denied.

GRIEVANCE #8

   Facts - A Mechanic Leader quit to find other employment. His job was posted
and eventually filled by a currently employed Mechanic "A". Because of changes
in the work load requirement, the Company did not rebid the repair "A" job and
left the job vacant.

   Issue - Did the Company violate the contract by leaving the Repair "A"
vacant and not bidding the job?

   Decision - The panel has decided that testimony regarding the elimination of
this job is conflicting and, therefore, directed the Company to officially
notify the Local Union within thirty days from this date whether the job has
been eliminated.

GRIEVANCE #9

   Facts - A number or Repair "A" jobs were bid on the second shift. The Plant
Manages interviewed each candidate individually and over a period of time in
excess of thirty days. 


61
<PAGE>   62


   Issue - (1) Did the Company violate the contract by not immediately awarding
the job?

           (2) Did the Company violate the contract by not having the full
Local Union present while these interviews took place?

   Decision - (1) The panel decided that the contract does not establish any
time period within which the Company must act. While the panel believes that
the Company should act within a reasonable period of time, The panel does not
have the authority to establish a time period. This is a subject for contract
negotiations.

           (2) The panel determined that the Plant Manager can interview
employees about their skill and ability without any Union representative
present during the interviews. However, the panel interprets the contract to
determine that the Plant Manager must meet with the Local Union before he
awards jobs to a junior employee on the basis of skill and ability 80 the Union
has an opportunity to discuss the qualifications of each and every bidder.
However, the panel points out that the Company makes the final decisions as to
whom the job is to be awarded and an unsuccessful bidder has the right to
challenge the Company's decision through the grievance procedure.

GRIEVANCE #10

   Facts - on an overtime day the Company was using both a front end loader and
a bulldozer to push stone and coal around the unloading station. After ten
hours the dozer operator declined to work any further overtime and went home.
The front end loader operator was also unable to stay any further on that day.
The Company then had a quarry utility operator operate the front end loader for
the balance of the time necessary to push the stoat and coal.

   Issue - Did the Company violate the contract by using the front end loader
to push coal rather than the bulldozes?

   Decision - The panel determined that the Company has the right to use either
the dozer or the front end loader to push coal. The quarry utility operator was
present and it is within his job description to operate the front end loader.
There was no violation of the contract. Therefore, the grievance is denied.

GRIEVANCE #11

    Facts - At 9:30 a.m. the foreman asked the grievant to work overtime from
4:00 p.m. to 8:00 p.m. The employee refused. The foreman made other arrangements
to fill the job. At 12:45 p.m. the grievant told the foreman that he had changed
his mind and that he could work. The grievant was made aware that the 4:00 p.m.
to 8:00 p.m. slot had already been filled, but he was offered the 8:00 p.m. to
12:00 a.m. slot. The employee declined to work the offered overtime. 


62
<PAGE>   63


   Issue - Did the Company violate the contract by not allowing the employee to
work the 4:00 p.m. to 8:00 p.m. overtime assignment?

   Decision - The panel has decided that an employee who refuses overtime
cannot subsequently change his mind if the Company has made arrangements to
have another employee perform the work. The grievance is denied.

GRIEVANCE  #12

   Facts - The 4600 dragline crew was scheduled to work overtime on a Saturday
night. The grievant was to work overtime from 11:00 p.m. to 7:00 a.m. with the
dragline crew. In addition, he had been awarded a new job which would commence
at 7:00 a.m. on Sunday. Solely because he was beginning a new job on Sunday at
7:00 a.m., the Company changed the overtime assignment and only had the
employee work from 3:00 a.m. on Sunday and then his new shift 7:00 a.m. to 3:00
p.m. on Sunday.

   Issue - Did the Company violate the contract by not working the employee the
hours he had been previously assigned to work?

   Decision - Under these, particular circumstances, the panel has decided that
the employee is entitled to four hours overtime pay at the rate of his old job.

GRIEVANCE #13

   Facts - On a Sunday there was need to push clinker in the covered clinker
storage area. The day shift dozer operator was a very experienced operator and
the second shift operator had only been on the job about two weeks. The
superintendent determined that on the particular day, the work assignment posed
special safety precautions and scheduled the experienced dozer operator to work
on that day.

   Issue - Did the Company violate the contract by not working the grievant
overtime since he was the low man in overtime in that classification?

   Decision - The panel has decided the Company is not required to equalize
overtime among employees holding the same job classification on a daily basis.
The Company is required only to equalize overtime "insofar as it is practical
to do so.

   Evidence supported the Company's position that it was not practical to
equalize overtime in these circumstances because the employee with the fewest
number of overtime hours in the classification had been on the job for only two
weeks and the overtime assignment required work of a specialized nature which
had to be assigned to a more experienced operator. The grievance is denied.


63
<PAGE>   64


GRIEVANCE #14

   Facts - There are two employees in the Truck Driver "C" classification. One
of the employees was called out on overtime on the day in question. The
grievant who was lowest man in overtime in the classification had already
worked twelve hours on that day and to have him perform the work would have
required the Company to work him over twelve hours.

   Issue - Did the Company violate the contract by not working the employee who
was lowest in overtime on the day in question?

   Decision - Again, the panel points out that the Company is not required to
equalize overtime on a daily basis, The employee with the fewest hours of
overtime had already worked overtime in the workday. The Company correctly
selected another employee for the callout. The grievance is denied.

GRIEVANCE #15

   Facts - The Company performed repair work on the 4600 dragline on an
overtime day. Repairmen were used to perform this work.

   Issue - Did the Company violate the contract by not having the 4600 Dragline
Operator and Pitman perform the work in question?

   Decision - The Company and the Union acknowledged that four different
classifications can perform repair work on the 4600 dragline: the Repairmen,
the Quarry Utility, the 4600 Operator and the 4600 Pitman. The panel agreed
that under these circumstances the Company did not violate the Labor Agreement.

GRIEVANCE #16

   Facts - On Friday night the transfer chain on the Marion No. 3 shovel came
off. The Operator and Pitman put it back on. Three hours later the chain came
off again and it was the Company's determination that repair of a once
permanent nature must be made. The shovel was shutdown. On Saturday, two "A"
Repairmen made the necessary repairs.

   Issue - Did the Company violate the Contract by not having the Shovel
Operator and Pitman work on that Saturday to perform the repair work rather
than the Repairmen?

   Decision - The panel has determined that the ruling in Grievance No. 15 is
also applicable in this instance. Repairman is one of the four classifications
which can and do perform repair work on the shovel. Therefore, the grievance is
denied.

<PAGE>   65


GRIEVANCE #17

   Facts - Immediately prior to 3:00 p.m. the 7:00 to 3:00 shift began having
trouble with the coal feeding through the feeder in one of the kilns. The
foreman held over a day shift repairman for four hours and said he would call
out the other shift repairman, but then changed his mind and then held the
employee over for eight hours.

   Issue - Did the Company violate the contract by holding the employee over
eight hours and not calling the off-man as had been the practice?

   Decision - The panel determined that there was no violation of the contract,
however since the foreman said he would call out the off-shift repairman and
then proceeded not to, a four hour call-out is granted due to these particular
circumstances without precedent.

   The panel further determined that the Local Union must assume the burden of
proof to show that the Company did not intend to divide overtime equally,
"insofar as it is practical to do so" among employees within the same job
classification by establishing a continuing pattern of assignment of overtime
to an employee other than the employee with the lowest overtime in the
classification without good cause.

   The panel directs the Company and Local Union to meet to establish written
guidelines for the purpose of interpreting the language in the overtime section
which states "insofar as it is practical to do so." Such guidelines must
recognize that overtime is not required to be equalized on a daily basis, since
the contract does not require this. Therefore, the guidelines must recognize
that there are reasons for using an employee other than the lowest in overtime
on a particular day such as experience, skills, qualification, overtime already
worked on that particular day, etc.

GRIEVANCE #18

   Facts - The grievant was asked earlier during the week of October 16th
whether he would work on Sunday, October 21st. The grievant declined. Later in
the week, the grievant was asked whether he would work Friday, October 19 and
Saturday, October 20th. The grievant declined to work either of these days but
he was not asked on this second occasion whether he would work on Sunday.

   Issue - Did the Company violate the contract by not asking the employee to
work Sunday the second time when he was approached later in the work week and
asked to work Friday and Saturday?

   Decision - The panel has decided that the grievant was offered overtime work
on each day in question and, therefore, the grievance is denied.


65
<PAGE>   66


GRIEVANCE #19

   Facts - A Mix Chemist who was scheduled to work did nor report for work. The
Plant Chemist filled the vacancy by holding over the Mix Chemist who was
working the prior shift and calling out Mix Chemist working the next shift four
hours earlier rather than calling out the off-man which had been the normal
procedure.

   Issue - Did the Company violate the contact by not calling out the off-man?

   Decision - While there was no violation of the contact, the Plant Chemist
admitted that he did not follow the established procedure. Therefore, four
hours callout is granted without precedent for any future grievances. however,
the panel points out as it did in Grievance #13 and #17 that the Company is not
required to equalize overtime on a daily basis. The Union must prove that the
Company does not intend to divide overtime equally insofar as it is practical
to do so among employees within the same Job classification by establishing a
continuing pattern of assignment of overtime to an employee other than the
employee with the lowest overtime in the classification without good cause.
This principle shall control the disposition of all future cases until such
time as the Company and Local Union agree to reasonable guidelines mentioned in
grievance settlement No. 13.

GRIEVANCE #20

   Facts - Two laborers assisted the 7400 Dragline Operator and the Pitman in
cleaning out the tub of the dragline because of the substantial amount of
cleaning out work required.

   Issue - Did the Company violate the contract by not paying the Laborers
Pitman rate and not calling off-work Pitman?

     Decision - Because of the amount of work and the nature of the work
involved, the panel determined that under these circumstances there was no
violation of the contract. Grievance is denied.

GRIEVANCE #1

   Facts - Three Quarry Mechanics were told by the foreman that they were to
report for work one hour early each morning until further notice to start and
warm up the mobile equipment in the quarry including the shovel.

   Issue - Did the Company violate the contract by not paying the Quarry
Mechanic a call-out?

   Decision - The panel determined that the Quarry mechanics were not entitled
to a callout and that there was no violation of the contract. The panel decided
that the Company had the right under the contract to require that employees
report early on an "until further notice" basis and were not required to notify
them each day. The panel agreement on the "standing order" then makes the
Company in accord with Article VII (d. (3)) which specifically states that "if
an employee is notified before the end of his regular scheduled shift, it shall
not be considered a call-out." The panel determined also that the employees who
were reporting one hour early did not have their schedules changed. A schedule
change is defined as a notification by the Company to an employee that he will
be required to work one or more hours, shifts, and/or days, in place of but not
in addition to the regular schedule. The one hour the Quarry Mechanics worked
was in addition to their regular schedule, and therefore, was not a schedule
change.

GRIEVANCE #2

   Facts - Because of a truckers strike of about two weeks, the Company did not
operate the second shift packhouse crew on a full production basis. The packing
crew was used elsewhere in the plant as needed.

   Issue - Did the Company violate the contact by not giving them the right to
bump?

   Decision - The panel determined that the Company did not violate the
contract by denying the employees the right to bump. It 


67

<PAGE>   68


was determined that an employees job is not eliminated until the Company
notifies him that his job has been eliminated and gives him a bump slip.

GRIEVANCE  #3

   Facts - The Plant Manager was measuring bolts on the new kiln mult-o-ring by
unscrewing the bolts and then replacing them and labeling them. There were no
bargaining unit employees with the Plant Manager at the time he was measuring
the bolts.

   Issue - Was the Plant Manager performing bargaining unit work and,
therefore, violating the contract?

   Decision - The Company violated the contract in the circumstances described
in this particular case. The Plant Manager should have had an hourly employee
with him who later would use this system which he was preparing and the hourly
employee should have physically measured the bolts. However, the panel decided
that this decision was without precedent for any other grievance since each
grievance under this contract clause must be taken on a case-by-case basis .

   Award - Four hours pay at double time (2x) to the repairman lowest in
overtime.

GRIEVANCE #4

   Facts - The Company posted six laborer jobs on the second shift to brick a
kiln during a planned shutdown. On this posting, it was stated that the jobs
were to run only as long as necessary to brick the kiln and when they were
eliminated that there would be no 95% rate protection.

   Issue - (1) Did the Company violate the contract by not paying the employees
95% rate protection when the jobs were eliminated?

           (2) Did the Company violate the contract by not giving the employees
written advance notice that their jobs wore being eliminated and should the
Company pay the employee out-of-schedule penalty since the time of the
elimination?

   Decision - The panel has decided that there was no violation of the contract
on either issue No. 1 or No. 2 but prior to giving this decision, the Local
Union dropped the grievance.

The Company's final position on Article VI (a) restricts bidding to any
employee in a classification whose straight time hourly rate is less than the
bid job, effective May 1, 1996.

This letter will confirm the Company's agreement to allow each employee in the
bargaining unit to bid on an equal or lower rated classification once during
the life of the new labor agreement which will take effect May 1, 1996.

This letter will also confirm the Company's agreement to allow each employee in
the bargaining unit to bid on any newly created job, or on a job created
through the combination of other jobs, during the term of the labor agreement
which takes effect May 1, 1996.

                                 ATTACHMENT "B"

The most efficient and productive method of operating a cement plant is on a
continuing process basis. Any time major equipment is shutdown due to operating
difficulties, the plant is at its weakest position. At this point it is in the
interest of both the Company and its employees that the equipment be returned
to normal operation in the shortest period of time, using the most efficient
and least costly methods available.

However, when major equipment must be shutdown due to operating problems, the
present contract severely limits the ability of the Company to make efficient
and productive use of its employees and equipment and even economically
penalizes the Company when it attempts to do so.

Continued application of these restrictions and penalties when operating
difficulties occur threaten the viability of each plant. This also encourages
the entrant into the market place of non union or other competitors who do not
have these contract language barriers and ace able to use their labor cost
advantages in their relationships with our customers.

In light of the above fact, the parties agree to the following language:

                             * * * * * * * * * * *

The eight hour rest penalties, scheduling penalties, double time after twelve
hours in a day, or double time into next shift penalties (however, double time
after 12 consecutive hours shall apply,) and seventh consecutive day penalties,
provisions of the current Collective Bargaining Agreement, shall not apply
whenever one or more of the unscheduled shutdowns listed below are present, and
the Company is in the process of returning the equipment to operation. The
kilns must be down sixteen (16) hours and the finish mill down eight (8) hours
because of operating difficulties before the above exemptions become effective.

1.  If any kiln is shutdown because of operating difficulties.

2.  a.   One or more finish grinding mills are shutdown because of operating
         difficulties.

    b.   One or more raw grinding mills are shutdown because of operating
         difficulties and would result in the shutdown of the kiln in the
         immediate future*.

3.  One or more crushers arc shutdown because of operating difficulties, and
    would result in the shutdown of the kiln in the immediate future*.


70
<PAGE>   71


    "Immediate future" means that the Company cannot bring the equipment that
    is shutdown back into operation at straight time in sufficient time to
    prevent the kiln from running out of the inventory provided by the disabled
    equipment such as raw-grind kiln feed, stone, etc.

The penalty exemptions shall commence when the equipment in, 1, 2, or 3, above
is shutdown and will not continue in effect for more than twenty-four (24)
hours after the equipment which has been shutdown has been returned to
operation; however, the seventh consecutive day penalty exemption will continue
until the seventh day of the plant workweek in the week the work was completed.
This seventh day exemption shall only apply to those employees used to return
the equipment to operation.

In addition, if a holiday or Sunday falls when one or more of the above
conditions are present, all employees who work on these days shall be
considered as scheduled to work for premium purposes under Article VII (d) (1)
regardless of whether or not they have been previously scheduled to work.

In addition, the penalty exemptions listed in this attachment shall not apply
to employees of the Packhouse or Quarry unless they are used to perform
maintenance on the equipment while it is being returned to operation or are
used to replace employees who are used to perform such maintenance.

If their work under these conditions would result in the application of any of
the penalties listed in this attachment, the penalties shall not apply.

The foregoing to the contrary notwithstanding, the above penalty exemptions
shall not apply during a scheduled plant shutdown.

During our recent contract negotiations the Company agreed that the last
paragraph of Article VII (f) (lunches) concerning reasonable time to eat a
lunch, will also apply to the situation where an employee has received twelve
hours notice prior to the commencement of the overtime assignment and is not
provided a lunch by the Company.

The Company will allow the employee thirty (30) minutes away from his job to
eat his lunch. However, it is understood that shift workers will continue to
eat their lunches on the job as they have done in the past.

In addition, the Company will not call an employee's home after ten o'clock at
night for the sole purpose of meeting the twelve hour notice requirement to
avoid providing an overtime lunch.

                                VOLUNTARY LAYOFF

This letter will confirm that the Union recognizes that the first paragraph of
Article V (b) of the Contract requires the most senior employees to perform
work in their classification when a production curtailment or plant shutdown
causes a reduction in the personnel in that classification.

The foregoing to the contrary notwithstanding, the Company, without precedence,
will consider the request from a senior employee to take voluntary layoff when
there is a reduction in personnel in his classification during a plant shut
down. The Company retains the right to decline these requests, but will not
unreasonably withhold such permission.

Whenever the request is granted by the Company, the Union acknowledges by its
signature below that the granting of each request is without precedence for any
future requests.

The requests will only be considered during a plant shutdown in which employees
are laid-off. The employee who requests and is granted voluntary layoff
consistent with this letter, will be recalled (1) when the Company needs the
employee for work in his classification or (2) when the plant starts up,
whichever occurs sooner, providing his seniority permits such recall.

It is understood and agreed to by the Union and the Company that the following
will satisfy the requirements of Article VII, section (f) regarding hot
lunches:

    1.  The Company will furnish a frozen food freezer or coin operated vending
        machines and a microwave oven to supply a lunch to an employee who
        satisfies the overtime requirements. The employee will be furnished
        $6.00 effective May 1, 1997 and $6.50 on May 1, 1998 to be used for the
        purchase of his hot lunch. The employee shall receive the money as
        stated, even if he chooses not to purchase a lunch.

    2.  The Plant Manager and Local Union Committee will agree in writing on
        the various types or kinds of food to be available.

    3.  The Company will allow the employee thirty (30) minutes away from his
        job to eat his lunch. However, it is understood that shift workers will
        continue to eat their lunches on the job as they have done in the past.

    4.  In the event an employee is unable to obtain a sandwich, soup and a
        beverage from a machine because one of them is empty, the Company will
        furnish a lunch provided a local restaurant is open.

    5.  Sandwiches will be dated as to the date they should be removed from the

It is understood by both Local 173 and the Company that the Job Evaluation
Request Form IR-74-2 in no way changes the Company policy pertaining to the
Wampum plant job evaluation program. The form is provided to allow for a
reasonable amount of information explaining the justification for a job
evaluation request when it is submitted to the plant management by an employee
so the request can be properly considered and validated.

Items one (1) through four (4), and ten (10), and eleven (11) will be filled in
by an hourly employee prior to submitting the form to the plant management. If
the request is deemed valid by management, the Union and management evaluation
committees will schedule a meeting and fill in items five (5) through nine (9)
on the evaluation form and perform an evaluation according to the current
evaluating policy.

              and terminate their employment on a specified date. Such dates
              must be in accordance with the time period specified in this
              section.

       (4)    The term of employment will not be changed, altered or extended
              unless mutually agreed to by both the Company and the Local Union
              Committee.

       (5)    Summer employees shall not accumulate seniority nor be eligible
              to bid on any new job or vacant job which may occur during their
              terms of employment.

       (6)    A summer employee will not become eligible for a floating  
              holiday and will not have any vacation rights.

       (7)    Summer employees will not participate in the Company's pension,
              S.U.B. and insurance programs.

       The above will be in full force and effect, except that if any portion
       is found to be contrary to any federal, state or local law, it shall be
       changed to comply with said law.


                                   ARTICLE IV

                                  JOB SECURITY

(a)    (1)    Whenever the installation of mechanical equipment, change in
              production methods, the installation of new or larger 
              equipment, the combining of jobs or the elimination 


                                      7

              of jobs, will have an effect on the job status of one or more 
              employees, the Company will give the Union reasonable advance
              notice of same and, upon request by the Union, will promptly
              meet with the Union to review and explore the effects of such
              installation or installations or change or changes upon the
              working force.

       (2)    Employees will not be terminated by the Company as the result of
              mechanization, automation, change in production methods, the
              installation of new or larger equipment, the combining of jobs or
              the elimination of jobs.

       (3)    Whenever an employee is no longer needed on his regular job as a
              result of circumstances described in (1) above, such employee may
              apply for any job or jobs within the bargaining unit on which an
              incumbent has less seniority, and for which he could reasonably
              be expected to qualify within a ninety (90) day on-the-job
              training period unless the employee applying for such job is
              disqualified due to physical reasons.

              The rate of pay for such employee shall not be less than
              ninety-five percent (95%) of the rate for the regular job from
              which he was displaced, irrespective of the rate of the job which
              he applies for and obtains.

              The ninety-five percent (95%) of rate protection shall apply for
              a minimum period of one (1) year, or a period equal to one-third
              (1/3) of an employee's seniority up to a maximum of two (2)
              years. If the affected employee is tendered training for a job
              which he could be reasonably expected to qualify for with a
              ninety (90) day on-the-job training period and refuses, he will
              not be entitled to any rate protection unless he has a bona fide
              reason for refusing. If an employee on ninety-five (95%) percent
              rate protection subsequently bids on and is awarded a lower rated
              job, he shall lose his rate protection.

       (4)    Employees affected by the application of the foregoing procedures
              shall have and may exercise the same rights for retention and
              on-the-job training in accordance with their seniority status and
              the ninety-five percent (95%) rate guarantee shall also be
              applicable to them.

       (5)    Employees who do not apply for and/or obtain a job in accordance
              with the provisions of (3), including employees displaced from
              their jobs but whose seniority status does not permit them to
              utilize job retention rights under the provisions of (3) or (4)
              will be placed on layoff status with recall rights in line with
              their seniority status for job vacancies which may thereafter
              occur.
       (6)    The provisions of (3) of this Section do not apply to
              displacements or layoffs resulting from production curtailments,
              except that employees laid off and not recalled when production
              is resumed following curtailment will be entitled to the same
              rights as employees affected by the preceding (3).


                                      8

       (7)    Should the Company permanently shutdown the present facilities
              affording employment to the employees comprising the bargaining
              unit (the present facilities shall be deemed to have been
              permanently shutdown if all productive facilities are abandoned
              even though the shipping facilities continue to operate), the
              Company shall mail a notice informing each affected employee that
              his employment with the Company has been terminated because of
              the permanent shutdown. The notice shall be mailed at least
              ninety (90) days prior to the shutdown to the employee's last
              address on the Company's records. Each employee who is mailed
              said notice shall have the following options:

       A.     An employee who is not eligible for a normal (excluding thirty
              (30) year retirement pension) or late retirement pension may
              elect to transfer to another operation of the Company covered by
              a collective bargaining agreement with the Union in accordance
              with paragraph 8 or paragraph 9.

              Any transfer pursuant to paragraph 8 or 9 will occur not later
              than three (3) years after the last day the employee worked. An
              employee awaiting transfer shall be placed on layoff and shall
              receive S.U.B. Layoff or reduced layoff benefit provided the
              eligibility and other requirements of the S.U.B. Plan are met. An
              employee may void his election to transfer at any time during the
              three (3) year period. If the employee is eligible for an
              immediate pension at the time he voids his election to transfer,
              he shall retire, effective the date he voids his election, under
              the pension plan in effect at the time of the permanent shutdown.
              An employee may also void his election in order to apply for
              S.U.B. Termination benefits.

       B.     An employee who is eligible for an immediate pension at the date
              of the permanent shutdown shall retire as of the effective date
              of the permanent shutdown, except

              1.    An employee whose combined age and years of service equal
                    62 or more but less than 65 may elect layoff until his
                    combined age and years of service equal 65 at which time
                    the employee shall retire and receive a permanent shutdown
                    pension. The pension plan in effect at the time of the
                    permanent shutdown shall determine the retirement benefits
                    payable to the employee. An employee who elects layoff
                    under these conditions shall receive S.U.B. Layoff or
                    reduced layoff benefits provided the eligibility and other
                    requirements of the S.U.B. Plan are met.

              2.    An employee who is eligible for an immediate pension other
                    than a normal or late retirement pension and who elects to
                    transfer to another operation of the Company shall not
                    retire unless the transfer is not accomplished.

              3.    An employee shall not be required to retire under a
                    disability retirement pension earlier than he would
                    otherwise be required to retire if the Company had not
                    permanently shut down the facilities.


                                      9
<PAGE>   10

              An employee who retires under the Pension Plan may also be 
              entitled to receive S.U.B. Terminations benefits in accordance 
              with the terms of the S.U.B. Plan.

       C.     The employee may elect S.U.B. Termination Benefits in accordance
              with the terms of the S.U.B. Plan at any time within one (1) year
              after notice of termination has been mailed to him.

              An employee other than an employee who is eligible for an
              immediate pension may elect layoff prior to submitting his
              application for S.U.B. Termination Benefits and shall receive
              S.U.B. Layoff or reduced layoff benefits provided the eligibility
              and other requirements of the S.U.B. Plan are met.

       D.     If the facilities which have been permanently shut down are 
              reopened by the Company within three (3) years of the date of the
              permanent shutdown, an employee who has retired under the Pension
              Plan shall be eligible for recall in accordance with his
              seniority status at the time of the permanent shutdown. An
              employee who has elected S.U.B. Termination benefits shall also
              be eligible for recall in accordance with his seniority status at
              the time of the permanent shutdown. Any pensioner who has 
              received S.U.B. Termination benefits and accepts recall and any
              former employee who has received S.U.B. Termination benefits and
              accepts recall shall repay said Termination benefits to the
              S.U.B. Trust Fund or to the Company, whichever was the source of
              the Termination benefits, in accordance with the S.U.B. Plan
              Agreement. Any employee who accepts recall shall have his
              previously accumulated seniority rights, pension, S.U.B.,
              insurance and vacation credits as of the last day the employee
              worked or at the date of permanent shutdown, whichever occurs
              later, reinstated on the date he returns to work.

       E.     An employee who is not eligible for an immediate pension may
              elect layoff and shall receive S.U.B. Layoff or reduced layoff
              benefits provided the eligibility and other requirements of the
              S.U.B. Plan are met.

              The employment rights of any employee on layoff shall terminate
              three (3) years after the last day the employee worked and the
              employee's seniority shall be broken.

       F.     An employee's participation in the group insurance program shall
              terminate effective the day following the last day the employee
              worked and pending claims shall be processed in accordance with
              the terms of the existing group insurance program. No employee
              shall be eligible for holiday pay or vacation pay other than
              vacation pay due after the last day the employee worked or the
              date of the permanent shutdown, whichever occurs later. No
              employee shall accumulate credited service under the pension plan
              after the last day the employee worked or the date of the
              permanent shutdown, whichever occurs later.

       (G)    THE COMPANY WILL ESTABLISH A 401(K) PLAN TO BEGIN AUGUST 1, 1998
              WITH EMPLOYEE CONTRIBUTIONS UP TO 4% TO BE MATCHED 50% BY THE
              COMPANY. BEGINNING MAY 1, 


                                     10
<PAGE>   11

              2000, EMPLOYEE CONTRIBUTIONS UP TO 5% TO BE MATCHED 50% BY THE
              COMPANY, AND MAY 1, 2002 EMPLOYEE CONTRIBUTIONS UP TO 6% TO BE
              MATCHED 50% BY THE COMPANY.

       (8)    In the event the Company constructs a new plant that will affect
              the employment status of employees in the Company's plant or
              plants comprising a bargaining unit, such employees shall be
              given an opportunity to make application for employment in the
              new plant before it starts operation, and such employees shall be
              given preferential employment right for the highest rated job the
              employee is capable of performing. Such an employee shall
              transfer with him all of his previously accumulated pension,
              S.U.B., insurance and vacation credits. His seniority rights at
              the former plant shall terminate upon his establishment of
              seniority rights in the new plant.

       (9)    When an employee has been laid off or displaced because of
              permanent changes in the working force or because of a plant
              closing, he may make written application within fifteen (15) days
              of layoff or displacement for employment in another plant of the
              Company, and he shall be given preferential employment rights for
              job openings at such other plant, providing such employee is
              capable of performing the job that may be available at such other
              plant of the Company. Any employee so transferring from one plant
              to another of the Company shall retain his previously accumulated
              pension, S.U.B., insurance and vacation credits. His seniority
              rights at the former plant shall terminate upon his establishment
              of seniority rights in the plant to which he transferred.

       (10)   Employees transferring from one plant to another as provided in
              (a) (7), (8) and (9) of this Article will receive a moving
              expense allowance. The Company will reimburse each employee for
              actual moving expenses incurred to move furniture and other
              household goods up to a maximum of $1,000 per employee.

(b)    When a production curtailment or a plant shutdown causes a reduction in
       personnel in a department or throughout the plant, a senior employee
       whose regular job is not required shall have the option of accepting
       available work for which he is qualified or accepting layoff. A Senior
       employee who elects to accept available work shall be entitled to:

       (1)    Bump any junior employee whose job was previously held by the
              senior employee on a permanent basis for a sufficient period of
              time to demonstrate his ability to satisfactorily perform the job
              as it is constituted at the time of the production curtailment or
              plant shutdown. The senior employee must attempt to bump into a
              job that he previously held in the reverse order of his
              promotions. In other words, he must first attempt to bump into
              the job he held immediately prior to his present job, except each
              employee may select one job that he had previously held on a
              permanent basis or is qualified to perform immediately, and for
              purposes of this section only, consider it to be the job he held
              immediately prior to his present job. Each employee 


                                     11
<PAGE>   12

              may make such selection and this selection shall be updated 
              effective on May 1, of each contract year at the employee's 
              discretion.

              If the above procedure would result in an employee becoming a
              part of the labor crew, he may exercise his bumping rights set
              forth in (2) prior to entering the labor crew.

       (2)    An employee can bump a junior employee on a plant-wide basis
              except for any maintenance job, any laboratory job, or those in
              the control room operator classification, provided he is
              qualified to perform the job immediately.

              Employees who hold utility or vacation-relief jobs where the
              employee actually works on several different jobs on a scheduled
              basis shall be considered as having held those classifications on
              a permanent basis for purposes of this section (b).

              Any junior employee who is displaced by a senior employee shall
              have the same rights as the senior employee set forth herein.

              After the bumping is completed, the Company has the right to
              require a senior employee to perform available work during the
              curtailment or shutdown if there is no junior employee with the
              necessary qualifications to perform the work.

              A plant shutdown is defined as a period during which none of the
              clinker burning units are producing.

              The wage rate paid during a production curtailment shall be the
              wage rate of the job performed. An employee who works on two or
              more jobs in one day shall be paid in accordance with Article V
              (j) (2).

              During periods of plant shutdowns when employees are needed for
              maintenance, repairs or work on plant alterations, the wage rate
              paid to employees who are retained for work during the first
              forty-five (45) days of plant shutdown shall not be less than the
              employee's regular straight time wage rate nominally paid when
              the plant is producing. After forty-five (45) days, the wage rate
              paid shall be the wage rate of the job performed. An employee who
              works on two or more jobs in one day shall be paid in accordance
              with Article V (j) (2).

              The ninety-five (95%) percent rate protection is not applicable
              to any bumping under this procedure.

(c)    When the Company determines that additional jobs are required during or
       following a production curtailment or a plant shutdown in order to
       maintain or increase the work force, the manner in which the reduction
       of forces took place pursuant to Article IV, Section (b) will be
       reversed.


                                     12
<PAGE>   13

       In the event that during a production curtailment or a plant shutdown an
       employee bids for and is awarded another job, he shall lose all rights
       pertaining to the job the employee previously held.

       Sections (b) and (c) of Article IV shall not add to, subtract from, or
       otherwise modify any maintenance training agreement by and between the
       Company and the International and/or Local Unions negotiated before or
       after the effective date of this Basic Agreement.

(d)    The Company agrees to post a notice at least one week in advance of an
       intended shutdown. Whenever a layoff is planned because of a change or
       reduction in plant production requirements, the Company will, not less
       than seven (7) calendar days prior to the effective  date of the layoff,
       post a bulletin stating the expected  extent of such layoff, and the
       expected effect on the work force. In the event the required notice is
       not given in accordance with the  above, the Company will pay the laid
       off employee(s) the scheduled  time lost at the applicable straight-time
       hourly rate. The seven (7) calendar day period shall commence on the
       completion of the third  shift following the day in which the notice was
       posted. The foregoing does not apply to disciplinary layoffs and layoffs
       because of curtailment made necessary by disaster or emergency
       conditions affecting the ability of the Company to physically operate
       the plant.

(e)    Company personnel excluded from the bargaining unit shall not regularly
       perform bargaining unit work except temporarily in an emergency; for
       training or instruction purposes, for testing, diagnosis, analysis or
       when necessary to prevent disruption of the flow of operations or when
       necessary to meet the interest of efficient operations.

       Should a Company person excluded from the bargaining unit violate this
       commitment the Company will be required to pay to the effected worker or
       workers double time (his or their) regular straight time hourly rate for
       anytime worked by person not included in the bargaining unit, with a
       minimum of four (4) hours pay. If there is no affected worker, the
       penalty for such work shall be paid to the worker lowest in overtime in
       the classification and/or department.

(f)    Any employee who becomes incapacitated and on the basis of competent
       medical opinion cannot perform the cubes of his/her regular job may
       exercise his/her plant seniority through the bumping procedure to move
       to any position within the bargaining unit at the plant for which he/she
       could qualify within a reasonable period of time but not to exceed 90
       days. This in no way affects the bidding right of the employee.

(g)    Any employee who is displaced by an incapacitated employee pursuant to
       paragraph (f) of this section, may exercise his/her plant seniority to
       bump into another position within the bargaining unit at the plant for
       which he/she is qualified in the same manner as covered in the job
       bidding procedure. The 95% rate protection is not applicable to bumping
       under paragraphs (f) and (g).

(h)    All vacancies and new jobs created shall be posted no later than the
       eighth day following the date the vacancy occurred or the new job was
       created. Said vacancies and new jobs shall be posted for seven (7) days
       to allow any employee to make application in writing for such job. The
       Company will consider every application in terms of:

       (1)    Seniority

       (2)    The applicant's skill and ability and physical fitness measured
              against the requirements of the job.

              Where two or more applicants' qualifications in (2) are
              relatively the same, seniority shall govern.

              If an employee proves unsatisfactory, he shall be reinstated to
              his previous job.

              An employee who bids for and is awarded a job, excluding any
              employee who is disqualified subsequent to the award, may not bid
              any job in the same or lower bracket for six (6) months from the
              date he was awarded his new job without the consent of the
              Company; except that an employee may bid from an operating job to
              a maintenance job or a laboratory job, from a maintenance job to
              an operating job or a laboratory job, or from a laboratory job to
              an operating job or a maintenance job even though the employee is
              bidding a job in the same or lower bracket within six (6) months.

              This Section does not require the Company to award a job to any 
              applicant if no applicants are qualified to perform the work.

              The Company has the right to assign any employee to fill a new
              job or to fill a vacancy until the job has been awarded.

              The Company will meet with the Local Union Committee to explain
              its decision when the Company awards a job to a junior applicant.
              Any senior applicant shall have the right to challenge the
              Company's award by filing a grievance in a timely manner. Any
              employee reinstated to his previous job shall have the right to
              challenge his disqualification by filing a grievance in a timely
              manner.

       (3)    Once a job has been awarded, the Company will make every effort
              to place the successful bidder on the job as soon as possible,
              but within thirty (30) calendar days from the date of the job
              award. Should the Company fail to place the successful applicant
              on the job in the 30 day period, the applicant shall receive the
              rate of pay for the new job commencing with the 31st day, until
              such time as he is placed on the new job. At that time, he will
              be paid in accordance with this Basic Agreement, Local
              Supplemental Agreement, or plant practice, whichever is
              applicable.

              This shall not apply if the delay beyond thirty (30) days is
              caused by multiple bidding to fill the original vacancy.

         *    If an employee is being paid the rate of double time under the
              foregoing paragraphs, his rate of pay shall not be reduced when
              his work continues into or overlaps his regular shift. However,
              the Company may exercise either of the following options:

       A.     The Company may instruct the employee to continue to the end of 
              the shift at the double time rate, or

       B.     The Company may send the employee home at any time during the
              shift, provided the remainder of the shift is paid for at
              straight time, subject to a maximum payment of four (4) hours at
              straight time. Such employee cannot be called back to work until
              he has been off duty for eight (8) consecutive hours.

              In no event shall the first two provisions of the Section be

       (3)    Callouts and Off-days: In case an employee is called for work
              during any hour in the day or week in addition to his regular
              schedule he shall receive a minimum of four (4) hours' pay for
              such work at the applicable overtime rate. However, if he is
              notified before the end of his regular shift to report early, it
              shall not be considered a callout. Callout hours and off-day
              hours are overtime hours. All Sunday callouts to be paid a
              minimum of four (4) hours at the applicable Sunday rate.

              at the applicable overtime rate shall be paid for any scheduled
              lunch period interrupted by a work assignment and either prior or

              shall be granted with pay for same at the employee's regular
              rate.

       (5)*   If an employee actually works seven consecutive workdays in the
              plant workweek, regardless of the number of hours worked on any
              workday, the employee shall be compensated by multiplying the
              regular straight-time hourly rate by one (1) for each and every
              hour worked during the seventh consecutive workday, and this
              premium shall be paid in addition to whatever compensation the
              employee is otherwise entitled to receive under any other Section
              of this Article.

(f)    Overtime paid on a daily basis shall not be duplicated on a weekly basis.

(g)    If an employee does not work a regularly scheduled workday through
       action of the Company, excused absence or because of a holiday, that day
       shall be considered as actually a day worked for all overtime purposes.

(h)    Limitations Upon Overtime:

       (1)    Every reasonable effort will be made by the Company to avoid
              requesting any employee to work overtime and the Company will
              consider under the circumstances involved any reasonable excuse
              from an employee for not working the overtime. Whenever an
              employee is laid off due to lack of work or because of
              curtailment of operations, no overtime work shall be scheduled on
              any work which the laid-off employee is capable of doing and is
              able to perform, except in cases of emergency repair or
              unscheduled absences of other employees. The foregoing to the
              contrary notwithstanding, a laid-off employee will not be called
              back to work unless there is at least thirty-two (32) hours work
              in the workweek for such employee.

       (2)    Overtime in the various job classifications shall be equally
              divided as defined by the Local Agreement insofar as it is
              practical to do so. Any employee who is contacted and cannot work
              the overtime including callouts will be charged with the number
              of hours actually worked or paid, whichever is greater or
              according to the Local Agreement. Overtime worked or charged
              shall be posted weekly in each department by the foreman.


                                     18
<PAGE>   19

       (3)    Employees who are called upon to work overtime shall not be laid
              off during their regular work time for the purpose of equalizing
              said overtime.

       (4)    The Company will continue its practice of allowing a fifteen
              minute paid wash-up time on continuous overtime beyond the end of
              his shift. In addition, the Company will continue its practice of
              paying overtime in fifteen (15) minute increments.

       (5)    A.  Any employee who has not been notified of his overtime 
                  assignment at least twelve (12) hours prior to the 
                  commencement of the overtime assignment and who works  more
                  than ten (10) consecutive hours, shall be provided with a
                  hot lunch which shall be eaten at the end of said ten (10)
                  consecutive hours, or as soon as  practical thereafter but no
                  later than 30 minutes after the ten hours. Any employee who
                  works in excess of fourteen (14) consecutive hours shall be
                  provided with an  additional lunch, and lunches will be
                  furnished at the end of every four (4) consecutive hours
                  worked thereafter.

              B.  Any employee who is called out and works more than four (4)
                  consecutive hours shall be provided with a hot lunch which
                  shall be eaten at the end of said four (4) consecutive hours.
                  In addition, said employee shall be provided with a hot lunch
                  every four (4) consecutive hours worked thereafter.

              There shall be no duplication of hot lunches under provisions A
              and B above. The employees shall be given reasonable time to eat
              his lunch without loss of pay.

       (6)    THE COMPANY AGREES THAT THE ALLOWANCE FOR OVERTIME MEALS WILL BE
              INCREASED TO $6.00 EFFECTIVE MAY 1, 1998, TO $6.50 EFFECTIVE MAY
              1, 2000 AND TO $7.00 EFFECTIVE MAY 1, 2002.

       (6)    The purpose and intent of this Agreement is to refrain from
              working an employee beyond sixteen (16) consecutive hours
              excluding lunch periods. The Company agrees that they will not
              work any employee beyond sixteen (16) consecutive hours excluding
              lunch periods unless no other classified employee is available to
              do the work.

              However, in the event that a vacancy occurs that would require a
              classified employee to work more than sixteen (16) consecutive
              hours, the Company will fill that vacancy with another classified
              employee who has primary overtime rights, an employee with
              secondary overtime rights, or other qualified employee in the
              stated order.

              This Agreement does not absolve an employee from the requirement
              to stay on the job until properly relieved. However, the Company
              is required to make a diligent effort to provide a relief at the
              end of the sixteen (16) hour period. The Company will not use the
              eight (8) hour rest clause as an excuse to require an employee to
              continue working after sixteen (16) hours.

(i)    Eight Consecutive Hour Rest Premium *

       (1)    An Employee should receive at least eight (8) consecutive hours
              off work within the fourteen (14) consecutive hours immediately
              preceding the start of his next scheduled shift. In the event an
              employee does not receive eight (8) consecutive hours off work
              within the fourteen (14) consecutive hours immediately preceding
              the start of his next scheduled shift, the Company shall exercise
              one of the following options:

              A.  Instruct the employee to report late for his next scheduled
                  shift by the number of hours his longest consecutive off-duty
                  period falls below eight (8) hours and pay the employee the
                  appropriate straight-time rate for those hours not worked
                  between the starting time of his scheduled shift and the time
                  he reports to work in accordance with the Company's
                  instructions. The appropriate straight time rate on the
                  workday Sunday shall be one and one-half (1.5) and on a
                  recognized holiday, two (2.0).

              B.  Instruct the employee to work at the starting time of his
                  scheduled shift. The employee shall receive a premium for
                  those hours worked which, if added to his longest consecutive
                  off-duty period, equal eight (8) hours. The premium shall be
                  determined by multiplying the regular straight-time hourly
                  rate by one (1). The premium shall be in addition to whatever
                  compensation the employee is otherwise entitled to receive
                  under any other Section of this Article.

       (2)    If an employee does not receive at least eight (8) consecutive
              hours off work within the fourteen (14) consecutive hours
              immediately preceding the start of callout hours worked on an
              off-day (provided that any of the callout hours worked occur
              within the hours the employee would have otherwise been scheduled
              to work had the employee not been scheduled off), the employee
              shall receive a premium for those hours worked which, if added to
              his longest consecutive off-duty period, equal eight (8) hours.
              The premium shall be determined by multiplying the regular
              straight time hourly rate by one (1). The premium shall be in
              addition to whatever compensation the employee is otherwise
              entitled to receive under any other section of this Article.

(j)    Wage Rate - Transfer and Assignments

       (1)    Employees temporarily transferred shall be paid the regular
              straight time hourly rate of the job being performed or the
              regular straight time hourly rate of his regular job, whichever
              is greater.

       (2)    An employee regularly scheduled to work on two or more jobs
              having different wage rates shall receive the highest rate for
              the entire week. If a job is regularly scheduled to be performed
              each week at least one workday in the workweek, the employee
              filling that job shall receive the highest wage rate for the
              entire week. An employee who is scheduled to work five workdays
              during the workweek on a job or jobs having a higher straight
              time hourly wage rate or wage rates than the employee's regular


                                     20
<PAGE>   21

              straight time hourly rate, shall be paid at the higher straight
              time hourly wage rate for the entire week. An employee who works
              on two or more jobs in one day shall receive the highest wage
              rate for only the time worked on the higher rated job. However,
              should the employee work on a higher rated job(s) for four (4) or
              more hours in the workday he will receive the higher rate of pay
              for the entire day. The term "entire week" used in this section
              shall mean the 168 consecutive hours beginning at 7:00 a.m. on
              Sunday and ending at 7:00 a.m. on Sunday. The term "entire day"
              used in this Section shall mean the 24 consecutive hours
              beginning at 7:00 a.m. and ending the following day.

              The 168 consecutive hours mentioned above shall begin at 7:00
              a.m. Monday and ending at 7:00 a.m. Monday, at Local D23,
              Clinchfield, Georgia.

       (3)    The Company shall have the right to utilize employees to perform
              any job; provided, however, overtime and callouts in any
              classification shall be offered to the available classified
              employees in that classification before other employees are
              assigned such work. See Attachment "B" for Letter of
              Understanding concerning transfers.

(k)    Sunday Work

       All hours worked by an employee on Sunday which are not paid for on a
       premium and/or overtime basis shall be paid at the rate of one and
       one-half (1-1/2) times the regular straight time hourly rate exclusive
       of shift differentials. There shall be no duplication or pyramiding of
       premium pay and/or overtime under this provision.

(l)    Reporting Pay

       Any employee who is required to report for work shall be given at least
       four (4) hours pay at the regular straight time hourly rate, and shall
       receive full pay for all time thereafter that he is required to remain
       on the premises ready for work. Any employee put to work on his regular
       working day shall receive full day's pay at the regular straight time
       hourly rate.

(m)    Funeral Leave

       An employee, upon the notification of the death of his or her father,
       mother, spouse, son, daughter, brother, sister, stepfather, stepmother,
       stepson, stepdaughter, half sister, half brother, mother-in-law,
       father-in-law, brother-in-law, sister-in-law, grandchild, grandparent,
       or spouse's grandparent, shall be granted his or her next three (3)
       scheduled working days off with pay (four (4) days off with pay if the
       employee is required to travel beyond a radius of 500 miles). Payment by
       the Company for such time lost shall be on the basis of eight (8) hours
       per day at the employee's regular straight time hourly rate, including
       shift differential.

       As used herein, brother-in-law is defined to mean (1) the brother of
       one's husband or wife, (2) the husband of one's sister, (3) the husband
       of the sister of one's spouse, and sister-in-


                                     21
<PAGE>   22

       law is defined to mean (1) the sister of one's husband or wife, (2) the
       wife of one's brother, (3) the wife of the brother of one's spouse.

       The above clause shall not apply to an employee who is laid off, except
       when an employee is notified to return to work effective on or before
       the day of the funeral he shall be granted full funeral leave with pay.

       The Company will notify a local union official of a death of an
       employee's relative as defined above as soon as the Company has been
       advised by the employee.

       The foregoing to the contrary notwithstanding, no bereavement payment
       will be made unless the employee attends the funeral nor will payment be
       made if there are more than fourteen calendar days between the date of
       death and the next scheduled workday.

(n)    Jury Duty

       Any regular employee (as distinguished from a probationary employee
       required to perform jury duty on a day he is scheduled to work, shall be
       excused from work on that day. The Company shall pay the employee the
       difference between the amount received for such jury duty and eight (8)
       hours at his regular rate of pay plus shift differential if involved.

       The day or days paid for such jury service shall be counted as eight (8)
       hours worked for the purpose of computing weekly overtime.

(o)    Shift Changes

       A shift employee may clock in up to 30 minutes prior to the actual
       starting time of his shift and relieve the employee that he is to
       replace. When properly relieved within this 30 minute period, the
       employee being relieved may clock out and leave the plant.

       Under such circumstances the pay received by the relieving and relieved
       employees shall be computed as though both employees had clocked in and
       out at the actual shift change time.

(p)    The Company agrees to resolve problems with employee parking at the
       Charlevoix Plant (and Clinchfield Plant).

(p)    Wash Time and Rest Breaks

       (1)    An employee who does not receive a paid lunch period shall dock
              out prior to the regular quitting time for his shift. However, he
              shall be permitted to leave his place of work 15 minutes prior to
              the regular quitting for his shift to wash provided that the
              employee is not required to work overtime. An employee does not
              receive 15 minutes away from the job to wash because he has been
              required by the Company to work up to but not after the regular
              quitting time for his shift, shall be compensated 


                                     22
<PAGE>   23

              for lost wash time by multiplying his regular straight time
              hourly rate by fifteen minutes (.25 hour). If the employee uses
              additional time to clean following the regular quitting time for
              his shift, he shall be paid as though he had clocked out at the
              regular quitting time.

       (2)    An employee who does not receive a paid lunch period and who is
              required to work overtime after the regular quitting time for his
              shift shall clock out no more than 15 minutes after he leaves his
              place of work. This shall not apply to an employee on call out.

       (3)    An employee who does not receive a paid lunch period will be
              allowed a 15 minute rest break away from his job during the first
              four hours of his regular shift. Break times shall be determined
              by the employee's foreman and the efficient operation of the
              plant shall be controlling. The 15 minute break shall be strictly
              construed to be the total time away from the job. Should any
              employee regularly be denied a break, he may file a grievance in
              a timely manner.

       (4)    The Company is not required to grant any employee who does
              receive a paid lunch period any wash-up time and any rest break.
              Furthermore, said employee shall eat his lunch "on-the-job" so
              that there is no interruption of operations.

(q)    Any other provisions of this labor agreement to the contrary not
       withstanding, no employee shall receive pay for any hour worked or
       unworked which singly or in any combination, exceeds triple his regular
       straight time hourly rate.


                                   ARTICLE VI

                               VACATIONS WITH PAY

(a)    Any employee who works during at least thirteen (13) weeks in either
       each calendar year or each anniversary year, as defined in the Local
       Agreements, shall be granted a vacation off work without loss of pay,
       according to the following schedule:

(b)    All employees who have completed one or more anniversary years of
       service but less than five (5) years of service will be entitled to two
       (2) weeks of vacation, provided they meet all other requirements of this
       Article.

       Employees who have completed five (5) or more anniversary years of
       service but less than fifteen (15) years of service will be entitled to
       three (3) weeks of vacation, provided they meet all other requirements
       of this Article.

       Employees who have completed fifteen (15) or more anniversary year of
       service, but less than twenty-five (25) years of service, will be
       entitled to four (4) weeks of vacation, provided they meet all other
       requirements of this Article.



                                     23
<PAGE>   24

       Employees who have completed twenty-five (25) or more anniversary years
       of service will be entitled to five (5) weeks of vacation, provided they
       meet all other requirements of this Article.

       Article VI (b) above to the contrary notwithstanding, no employee (who
       meets all the other requirements of this Article Vl) shall be entitled
       any fewer weeks of vacation than he was entitled to take in 1984.

(c)    Vacation pay will be based on a forty (40) hour week at the rate of the
       permanently assigned classification on which an employee is working at
       the time he takes his vacation. If an employee has held a single higher
       rated classification for more than six (6) months during the year
       preceding his vacation, he will receive vacation pay computed at the
       higher rate. Vacation pay shall include appropriate shift differential
       for those on fixed shift. Employees working on rotating shifts shall be
       paid an average of the rates for the rotating shifts involved.

(d)    Vacations will not be cumulative, but so far as practicable, be granted
       at times most desired by the employees, but the final right to allotment
       of vacation period is exclusively reserved to the Company in order to
       insure the orderly operation of the plant. In exercising its right to
       allot vacation periods, the Company will not require any employee who is
       on layoff to take his vacation during periods of plant shutdown or
       curtailment of operation. Where requested vacation periods conflict,
       preference shall be given to the older employee in point of service.

(e)    It is further agreed that if any employees have previously selected
       their vacation period so that it occurs during an unforeseen shutdown
       such vacation period shall not be changed.

       Vacation shall be taken by the employee within the calendar year in
       which it is granted as determined by the Local Agreements.

(f)    No employee will be required and/or requested to work during his seven
       day vacation period. The only exception will be when a classification
       has two or fewer employees, no qualified personnel are available except
       the employee on vacation, and an emergency situation exists. In that
       event an employee on vacation may be requested to work.

(g)    The rules governing the submission of appropriate vacation application
       blanks shall be defined by the Local Agreement.

(h)    Upon two weeks written notice by an employee to the Personnel Clerk, the
       Company will give him his vacation pay on the employee's last shift
       prior to the beginning of his vacation.

                                  ARTICLE VII

                                    HOLIDAYS

(a)    The Company will grant eleven (11) paid holidays; these holidays shall 
       be listed in each Local Agreement.

(b)    If any such holiday falls on Sunday, the following Monday shall be the
       recognized holiday. The holiday hours shall be those hours within the 24
       hour period commencing with the beginning of the first shift on the
       morning of the holiday and ending at the beginning of the first shift
       the following day.

(c)    Employees who are scheduled to work on a holiday shall be paid two 
       and one-half (2.5) times the regular straight time hourly rate.

(d)    Hours worked on a holiday in excess of eight (8) in a workday, in excess
       of forty (40) in a workweek, on off-days, and on callouts shall be paid
       for at the applicable overtime rate.

(e)    If no work is required of an employee on the above holidays, he will
       receive eight (8) hours pay at the regular straight time hourly rate,
       provided he meets the following qualifications.

       (1)    The employee shall have been employed by the Company for at least
              thirty (30) calendar days prior to the holiday.

       (2)    The employee shall have worked his last scheduled working day
              prior to and his next scheduled working day after such holiday
              unless excused therefrom by the Plant Manager on account of
              sickness, accident, death in the family, or other excused
              absence. In no event shall a holiday be paid for unless employee
              has also worked during the thirty (30) day period immediately
              preceding or immediately following the holiday except that the
              thirty (30) day limitation shall not apply if the employee was
              temporarily absent from work because of sickness, accident or
              layoff. In any event, the employee must work at least one day in
              the calendar year in which the holiday is granted.

(f)    If an employee is scheduled to work on a holiday and fails to work, he
       shall not receive holiday pay, unless excused therefrom by the Plant
       Manager.

(g)    If an employee works on a holiday, the holiday shall be counted as a day
       worked for computing weekly overtime. Paid holiday is to count as a day
       worked for overtime purposes, provided holiday falls on one of
       employee's scheduled workdays and he would have worked that day except
       for holiday observance.

(h)    An employee not scheduled to work the holiday and who subsequently
       performs work on a holiday will be considered as being on callout and
       will be paid eight (8) hours at the regular 


                                     25
<PAGE>   26

       straight time hourly rate in addition to two (2) times the regular
       straight time hourly rate for all time worked with a minimum of four (4)
       hours at double time.*

(i)    Work schedules for each workweek which include a holiday will be posted
       prior to the end of the first shift on Thursday of the previous week. If
       an employee is scheduled to work on a holiday, but then instructed by
       the Company not to work, he shall receive for that holiday eight (8)
       hours pay at two and one-half (2.5) times the regular straight time
       hourly rate.

(j)    The phrase "regular straight time hourly rate" as used solely in Article
       Vll, Holidays, shall mean the higher of either the employee's regular
       straight time hourly rate or to the highest straight time hourly rate
       for a job on which the employee works at least eight (8) consecutive
       hours in the workweek in which the holiday falls provided (1) that the
       eight hours had been previously scheduled or (2) the hours are worked
       the day before or the day after the holiday whether previously scheduled
       or not.


                                  ARTICLE VIII

                                     WAGES

(a)    Considered a part of the Local Agreements are the current Job
       Classifications and Rate Lists.

(b)    (1)    Scheduled shift workers on the first shift shall receive the 
              regular straight time hourly rate.

       (2)    Scheduled shift workers on the second shift shall receive the
              regular straight time hourly rate plus 52(CENT) PER hour.

       (3)    Scheduled shift workers on the third shift shall receive the 
              regular straight time hourly rate plus 75(CENT)PER Hour.

       (4)    These premium rates do not apply to day workers even though they
              may work over into premium paid shift.

       (5)    If a day worker is scheduled to take the place of a regular
              scheduled shift worker, then the premium rate for the shift shall
              apply.

       (6)    The premium pay does not alter the provisions covered in this 
              contract under the head of "Working Conditions".

(c)    Shift differentials shall be included as part of the regular rate in the
       calculation of overtime compensation.


                                     26
<PAGE>   27

(d)    The Company may at its discretion increase wages in any class or to an
       individual in any class without necessitating a change in the rate of
       any individual or class.

(e)    Any job not mentioned in this Agreement or any job with substantial
       changes in duties, equipment or requirements, or any new job created in
       the plant, shall be open for negotiations by the Company and the Union
       as to wages upon written notice from either party to the other party. If
       no agreement can be reached during the above negotiations, the matter
       shall be subject to the grievance procedure.


                                   ARTICLE IX

                             HANDLING OF COMPLAINTS

(a)    All employees shall at all times make an effort to perform their duties
       in such a manner as to promote safe and efficient operation of their
       department and the plant as a whole.

       (1)    Should a difference arise between an employee and the Company as
              to the meaning and application of this Agreement or should a
              difference arise as to the meaning and application of a
              recognized practice, the employee with or without his steward
              shall present his complaint to his foreman within ten (10)
              working days after the date of the alleged wrong or within ten
              (10) working days after the date the employee received his
              payroll check, whichever is later. Failure by the employee and/or
              the Union to observe this time limit shall cause the grievance to
              be considered settled in favor of the Company.

       (2)    The foreman shall orally reply to the employee within five (5)
              working days after the date the employee presented his complaint
              in Section (1). Failure by the Company to observe this time limit
              shall cause the grievance to be considered settled in favor of
              the employee.

       (3)    If the employee is not satisfied with the foreman's reply, the
              employee may request his steward to present the grievance in
              writing to the Union Grievance Committee. If the Union Grievance
              Committee believes that the complaint is justified, it may submit
              the complaint in writing to the Plant Manager within five (5)
              working days of the date of the foreman's reply in Section (2).
              The Plant Manager shall schedule a meeting with the Union
              Grievance Committee and any member or members of the staff that
              the Plant Manager desires to have present. This meeting shall
              take place within fifteen (15) working days of the date the Union
              Grievance Committee submits the grievance to the Plant Manager.
              Failure to observe any time limit shall cause the grievance to be
              considered settled in favor of the employee if the Company has
              failed to observe the time limit or in favor of the Company if
              the employee and/or the Union has failed to observe the time
              limit.


                                     27
<PAGE>   28
       (4)    The parties shall use their best efforts to settle the complaint.
              If the parties agree upon the disposition of the grievance, they
              shall reduce their understanding to writing and the grievance
              shall be settled. If the parties are unable to agree, the Union
              Grievance Committee may at the employee's request and within
              thirty (30) days of the date of the meeting between the Plant
              Manager and the Union Grievance Committee submit the grievance in
              writing to the Director of Industrial Relations or his
              representative with copies to the International Vice President or
              District Council Representative and the Plant Manager. The
              Director of Industrial Relations shall contact the International
              Vice President or District Council Representative within seven
              (7) days after receipt of the grievance to schedule a meeting.
              The parties shall use their best efforts to schedule the meeting
              within thirty (30) days. Failure to observe any time limit shall
              cause the grievance to be considered settled in favor of the
              employee if the Company has failed to observe the time limit or
              in favor of the Company if the employee and/or the Union has
              failed to observe the time limit.

       (5)    After full consideration, and such conference as may be mutually
              agreed upon with an International or District Council
              Representative of the Union, the grievance shall be considered
              settled when the employee's and the Company's representative
              shall have reached an agreement.

       (6)    If the parties are unable to settle the grievance, either party
              can notify the other party in writing that it intends to submit
              the grievance to arbitration. This notice must be given within
              ten (10) days FROM THE RECEIPT OF THE WRITTEN RESPONSE FROM THE
              COMPANY. The consent of the other party is not required to
              arbitrate a grievance.

              The foregoing to the contrary notwithstanding, either party may
              exercise the following option:

              For the purpose of expediting and facilitating the resolution of
              a grievance which has been processed through step (5) of the
              grievance procedure and which would otherwise be submitted to
              arbitration, either the Company or the Union may elect to submit
              said grievance to a panel which will consist of a Vice President
              of the International Union or his representative and the Vice
              President of Operations of the Company or his representative,
              provided that no member of the panel can be a party to any
              discussion of the grievance during an earlier step of the
              grievance procedure. Each party can submit a maximum of five (5)
              grievances to the panel during any calendar year. Only a
              grievance about the interpretation of contract language in the
              Basic or Local Agreement can be submitted to the panel. A party
              electing to submit said grievance to the panel must notify the
              panel and the other party within ten (10) days after a decision
              has been made at step (5). The authority of said panel shall be
              no greater than the authority of the arbitrator as set forth in
              (d) of the grievance procedure. The panel shall meet at the Plant
              where the grievance arose.

              A maximum of two members of the Union Grievance Committee can
              attend a panel meeting. The decision of the said panel shall be
              final and binding upon the Company 


                                     28
<PAGE>   29

              and the Union. In the event the Union representative on the panel
              and the Company representative on the panel are unable to agree,
              either the Union or the Company may elect to submit such
              grievance to arbitration as provided in step (6) of the grievance
              procedure. The party electing to arbitrate the grievance must
              give notice to the other party within ten (10) days after the
              Union representative on the panel and the Company representative
              on the panel have jointly informed the parties that the panel is
              unable to make a decision. Failure to observe any time limit
              shall cause the grievance to be considered settled in favor of
              the employee if the Company has failed to observe the time limit
              or in favor of the Company if the employee and/or the Union has
              failed to observe the time limit.

(b)    If either party does not notify the other within ninety (90) days of the
       notice of its intent in (a) (6) above, that it now wishes to mutually
       select an arbitrator and schedule a hearing date, then the parties shall
       consider the grievance to have been withdrawn by the moving party.

       When the moving party notifies the other of its wish to mutually select
       an arbitrator, the parties shall select an arbitrator within ten (10)
       days. Failing to reach an agreement upon the selection of an arbitrator,
       the moving party may request the appointment of an arbitrator by either
       the Federal Mediation and Conciliation Service or the American
       Arbitration Association.

       Grievances heard by the arbitrator must be presented in chronological
       order based on the date the grievances were written except in discharge
       cases which may be presented out of chronological order or in cases
       where the parties have mutually agreed in writing to waive the
       chronological order requirement.

(c)    All time limits set forth in (a) and (b) shall be strictly observed;
       time limits can be extended by a written agreement between the parties.

       Whenever the term "working days" occurs in the grievance procedure, it
       shall be defined by the parties to mean plant work days, Monday through
       Friday.

       Whenever the term "days" is used in this section, it shall be defined by
       the parties to mean calendar days.

(d)    The arbitrator shall consider only the grievance appealed to him and
       shall have jurisdiction and authority only to interpret, apply, or
       determine compliance with the provisions of this Agreement, and only the
       extent necessary to determine the grievance. The arbitrator shall not
       have jurisdiction or authority to add to, modify, detract from, or alter
       in any way the provisions of this Agreement.

(e)    The arbitrator's decision shall, at the request of either party, be in
       writing and shall be final and binding on both parties. The fees and
       expenses of the arbitration proceeding, except fees for witnesses
       brought in by either party and legal counsel's fees, shall be borne
       equally 


                                     29

       by the Company and the Union. Bargaining unit employees including 
       Committeemen who participate in arbitration proceedings shall not be 
       compensated by the Company.

(f)    Grievances involving the provisions of the collective bargaining
       agreement and occurring so as to be processed to arbitration at the same
       time will be at the request of either party arbitrated before the same
       arbitrator. However, it is agreed that not more than four (4) cases will
       be heard at one series of hearings.

(g)    Local Union officers and stewards off-duty and representatives of the
       International Union and District Council shall, upon notice to the
       Company, be permitted on Company's premises to investigate grievances.
(h)    Meetings will be conveniently scheduled so as to complete all business
       within the normal working day for day employees. Any employee who is
       scheduled to work during the hours the meeting is held and who attends
       the meeting will be compensated by multiplying the regular straight time
       hourly rate by the hours he attends the meeting. In addition, if the
       employee attends the meeting beyond his normal quitting time, he will be
       compensated for each additional hour he attends the meeting by
       multiplying the regular straight time hourly rate by one (1) and said
       additional hour or hours shall not count toward daily or weekly
       overtime.

       Any member of the Committee who is not scheduled to work during the
       hours the meeting is held, who is not scheduled to work the third shift
       immediately preceding the meeting, or who is not scheduled to work the
       second shift immediately following the meeting, and who attends the
       meeting, will be compensated by multiplying his regular straight time
       hourly rate by all hours he attends the meeting. Any hours paid under
       this paragraph shall not count toward the calculation of any penalty or
       premium pay section of this Agreement including but not limited to daily
       or weekly overtime. Any employee who is receiving S.U.B. benefits,
       sickness and accident benefits, or Workmen's Compensation benefits for
       the day of the meeting or who is absent due to disciplinary layoff shall
       not receive any compensation under this paragraph.

       When a meeting is scheduled at which a representative of the
       International Union and a representative of the Company from Cleveland
       will attend, any member of the committee who is scheduled work the third
       shift immediately preceding the meeting will be excused from working the
       third shift and will be compensated by multiplying eight (8) hours at
       the regular straight time hourly rate plus shift differential if the
       employee has attended the meeting.

       Any member of the committee who is scheduled to work the second shift
       immediately following the meeting will be excused from working the
       second shift if the employee has attended the meeting for six (6) hours.
       In the event the employee is excused from working the second shift, he
       will be compensated by multiplying eight (8) hours at the regular
       straight time hourly rate plus shift differential.


                                     30
<PAGE>   31

(i)    The Company will reimburse no more than two (2) members of the Union's
       bargaining Committee from each Local Union for scheduled time lost due
       to attendance at and travel to and from Basic Agreement Negotiations.
       One day travel time shall be allowed the day before such meeting, and
       one day travel time shall be allowed after such meeting. The rate of pay
       will be the regular straight time hourly rate including Sunday premium,
       if applicable.

(j)    Disciplinary letters issued to employees will remain in the Company's
       employee file for twelve (12) months. At the end of the twelve (12)
       month period, the disciplinary letters will not be used against the
       employee in the future for purposes of progressive discipline.

       This provision shall not apply if the discipline letter refers to a
       disciplinary suspension of one week or more.

(k)    Where there is a discussion between an hourly employee and a supervisor
       that is intended as a disciplinary measure, the Company requests that a
       grievance committeeman, job steward or other designated employee be
       present.

       A "disciplinary measure" shall be limited to the issuing of a reprimand
       or the imposition of a penalty to an employee about which a notation,
       letter or unsatisfactory performance report is subsequently made part of
       the employee's personnel file.

       It shall be the responsibility of the Union to appoint and have
       available on each shift a committeeman, job steward or other employee
       designated for purposes of this section who shall be identified to the
       Corporation in writing.

       It is not the intent of this Section to expand the total number
       committeemen as provided for in each Local Supplemental Agreement.

(l)    DISCIPLINE OF ONE WEEK OR MORE WILL NOT BE USED AFTER FIVE YEARS.

(l)    When a grievance involving pay is settled in favor of the Union, the
       employee entitled to such pay shall be paid by the second pay following
       the settlement.


                                   ARTICLE X

                              STRIKES AND LOCKOUTS

(a)    Having provided an orderly procedure for settling all disputes, the
       Company agrees not to lock-out its employees and the Union agrees that
       there will be no strikes or work stoppages during the term of this
       Agreement.

(b)    The Company agrees not to hold the Union liable when such activities are
       not authorized by the Union, provided that the Union within forty eight
       (48) hours orders its members to cease and desist from such activities.


                                     31
<PAGE>   32

(c)    It shall not be a violation of this Agreement or cause for disciplinary
       action including discharge if an employee refuses to cross a picket line
       that has been established in full compliance with existing laws. Picket
       lines established as a result of jurisdictional disputes, picket lines
       established for the purpose of organizing in-plant non-bargaining unit
       personnel, and/or informational picket lines are excluded from this
       protection.

       Notwithstanding the above, employees will not honor any picket line
       unless authorized by the International Union. The International Union
       will not be held liable for any subsequent damage to the Corporation
       resulting from refusal of employees to cross an authorized picket line.

                                   ARTICLE XI

                                     SAFETY

(a)    The Company will, according to its established practice, continue to
       install such safety devices for the protection of the lives and health
       of its employees as are required by the Workmen's Compensation laws of
       the State in which the plants covered by this Agreement are located. The
       Company  will maintain the washhouse with heat, light and plenty of hot
       water,  and keep the toilets, fixtures and floors in a sanitary
       condition, and will supply good drinking water wherever necessary about
       the plant.  Sufficient equipment and tools shall be maintained in a safe
       and efficient  working order, and the regulations and safety codes
       adopted by the Department of Labor of the applicable state, in the
       interest of protecting the safety and health of industrial employees as
       they affect this  industry, be strictly observed by both parties.

(b)    The Company agrees to furnish first aid and medical service to its
       workers in any cases originating out of their work in the Company plant,
       in compliance with the Workmen's Compensation laws of the applicable
       state. Medical  services shall be performed by a doctor to be agreed
       upon by the Company and the plant safety committee, but at the request
       of the injured, and the approval of the Plant Manager and Director of
       Industrial Relations, other medical aid may be called in at the expense
       of the Company for consultation or treatment of any cases. It is agreed
       that a complete medical examination  may be required before an applicant
       is employed. Also, that complete  medical examination may be made
       annually or at any time at the discretion of the Company. Copies of such
       reports and examinations will be kept on file by the Company and shall
       at all times be available for inspection to such  employees. Copies
       thereof shall be furnished to such employee's designated physician upon
       request.

(c)    A Joint Safety and Health Committee shall be established consisting of
       four members, two appointed by the Company and two appointed by the
       Local Union. In the event that a member is absent from a meeting of the
       Committee, his alternate may attend and when in attendance shall
       exercise the duties of the member. The Safety Director or his designee
       will be the fifth member and act as Chairman of the Committee.


                                     32
<PAGE>   33

       The Joint Committee shall meet as often as necessary, but not less than
       once each month at a regularly scheduled time and place for the purpose
       of jointly considering, inspecting, investigating and reviewing health
       and safety conditions and practices and investigating accidents and for
       the purpose of jointly and effectively making constructive
       recommendations with respect thereto, including but not limited to the
       implementation of corrective measures to eliminate unhealthy and unsafe
       conditions and practices and to improve existing health and safety
       conditions and practices. All matters considered and handled by the
       Committee shall be reduced to writing, and joint minutes of all meetings
       of the Committee shall be made and maintained. One union representative
       to the Committee will accompany a Federal or State investigator on a
       walk-around inspection or investigation, and will attend any pre-or
       post-inspection conferences. All time spent in connection with the work
       of the Committee by a Union Representative including all time spent in
       pre-or post-inspection conferences and walk-around time spent in
       relation to Federal and State inspections and investigations as provided
       for above, shall be compensated at the employee's regular straight time
       hourly rate. Any time spent during the hours the employee is scheduled
       to work shall count toward the calculation of any penalty or premium pay
       section of this Agreement including, but not limited to daily or weekly
       overtime. Any time spent outside of the hours the employee is scheduled
       to work shall not count toward the calculation of any penalty or premium
       pay section of this Agreement. No time spent outside of the hours the
       employee is scheduled to work shall be compensated at a rate greater
       than one (1) times the employee's regular straight-time hourly rate.

       Any employee who believes his job presents a hazard to his safety or
       health may request an immediate review of his job by the Joint Safety
       and Health Committee.

       No employee shall be disciplined or discharged for refusing to work on a
       job if his refusal is based on a bona fide claim that said job is not
       safe or might unduly endanger his health or safety.

(d)    (1)    An employee shall be paid a premium when he is required to:

       A.     work within a kiln during the first ten (10) hours that the kiln 
              has been shutdown after it has been operating at a normal level;

       B.     work within a cooler during the first two (2) hours that the 
              cooler has been shut down after it has been operating at a normal
              level;

       C.     work within a kiln precipitator during the first four (4) hours
              following the shut down of the kiln providing the precipitator
              was handling the kiln gases at the time of kiln shutdown;

       D.     work within a section of a kiln precipitator or a kiln baghouse
              while the kiln is in operation and the other sections of the
              baghouse or the precipitator are in use.



                                     33
<PAGE>   34

              The premium shall be calculated by multiplying the regular
              straight time hourly rate by one-half (0.5) for each and every
              hour worked up to the 10, 2, and 4 hours mentioned in A, B and C
              above and for 1/2 the hours worked in D above. Said premium shall
              be paid in addition to whatever compensation the employee is
              otherwise entitled to receive under any other section of this
              Agreement.

       (2)    Each Plant Safety Committee will meet to determine those areas of
              the Plant where an employee is subject to excessive radiant heat
              for extended periods of time. The Committee will consider all
              conditions which affect the level of heat encountered including
              ambient air temperature. Upon making said determination, the
              Committee will decide what the Company shall provide as
              reasonable protective apparel against excessive radiant heat.

       (3)    In the event that an employee is required to work on top of
              roofs, silos, scale a quarry face or work in a silo under
              conditions that are hazardous to an employee's safety, the hours
              worked shall be compensated for by multiplying the regular
              straight time hourly rate by one-half (0.5) for each and every
              hour worked that is deemed hazardous, and this hazardous work
              premium shall be paid in addition to whatever compensation the
              employee is otherwise entitled to receive under any other section
              of this Agreement.

(e)    Should the Company require an employee to wear foot protection, the
       Company will furnish such protection without cost to the employee. The
       liability of the Company with regard to safety shoes will be limited to
       not more than two (2) pair in any one year. A new pair of shoes will
       only be provided an employee when the worn out pair is turned in for
       replacement.

(f)    If a mandatory eye protector program is adopted: (1) the Company will
       pay for the cost of the eye examination if safety glasses with
       corrective lenses are required; (2) the Company will pay for safety
       glasses whether or not the glasses require corrective lenses. Safety
       glasses with or without corrective lenses will not be replaced more than
       once a year unless broken or otherwise damaged on the job.

(f)    THE COMPANY AGREES TO ALLOW AN $80 REIMBURSEMENT FOR SAFETY SHOES
       BEGINNING MAY 1, 1998. THIS ALLOWANCE IS TO BE INCREASED BY $2.50 ON THE
       ANNIVERSARY DATE EACH YEAR OF THE AGREEMENT.

(g)    The Company shall furnish all tools and equipment for its employees
       except to repairmen and other skilled trades, in which case these
       employees shall  furnish their own hand tools. "Hand tools" as used
       herein shall not include socket sets, wrenches more than twelve (12)
       inches long, and all other  specialized tools incident to the work of
       the mechanical, maintenance and skilled trades. Any hand tool that the
       employee uses in the performance of his job duties will be replaced by
       the Company if they are broken, worn out, lost or stolen. Unusable tools
       will be presented to the Company prior to replacement. Lost or stolen
       tools must be immediately reported to the Company for replacement
       approval. 


                                     34
<PAGE>   35

       Employees temporarily transferred to maintenance classifications shall
       be supplied with necessary tools.

(h)    The Furnishing of Gloves: The Company will continue its existing local
       practices regarding the furnishing of gloves.

       Employees who are not presently receiving gloves under existing local
       practices shall receive one pair of gloves at the beginning of each
       contract year, and each such employee shall receive a maximum of one
       additional pair per contract year from the Company upon return of his
       worn out gloves.

       In the event such an employee wears out and returns the two pairs of
       gloves provided to him, the Company shall sell him an additional pair of
       gloves for each worn out pair of Company provided gloves he returns.
       Said gloves shall be sold to the employee at the price paid by the
       Company.

(i)    If the Company requires an employee to take a physical examination, the
       Company agrees to pay for the physical examination and also agrees to
       pay the employee at his straight time hourly rate for all time spent in
       the doctor's office taking the physical examination; provided, however,
       employees receiving S & A and/or Workmen's Compensation benefits are not
       entitled to any compensation under this section. (Doctor releases for
       returning to work are not considered physical examinations and will not
       be paid under this section).


                                  ARTICLE XII

                                MILITARY SERVICE

(a)    The Company and the Union shall comply with the Universal Military
       Training and Service Act of 1950, as amended.

(b)    Active employees with one year seniority and who are in the Reserve of
       any branch of the military service, including the National Guard, who
       are required to attend a summer encampment as part of their Reserve
       obligation shall receive from the Company the difference between the
       amount of pay received for such encampment and his regular straight time
       hourly rate of pay for up to a maximum of two (2) weeks per calendar
       year.


                                  ARTICLE XIII

                     SUPPLEMENTAL UNEMPLOYMENT BENEFIT PLAN

The Company agrees to pay out of its funds (and not out of the Trust Fund
established under Article III of the Plan) benefits in amounts equal to those
provided by Section 2 of Article VIII of the Plan upon termination of
employment on or after May 1, 1965, after an employee (as defined 


                                     35
<PAGE>   36

in Section 6, Article II of the Plan) is sixty-five years old, provided such
employee is not eligible for a pension under the current Pension Plan for
Hourly Employees of the Company.

The foregoing to the contrary notwithstanding, the above payment shall not be
paid directly by the Company until termination benefits paid from the Trust and
Contingent Funds exhaust those funds.

                                  ARTICLE XIV

                                 SUBCONTRACTING

(a)    The Company will not contract for production or maintenance work
       customarily performed by its own employees unless it is more economical,
       expeditious, and/or efficient to do otherwise.

(b)    The Company may enter into contract arrangements for obtaining raw
       materials, semi-finished or finished products.

(c)    Notwithstanding the above, the Company will not contract or subcontract
       work covered by Paragraphs (a.) or (b.) above if it will directly result
       in the 1) laying off of (or failure to recall qualified) bargaining unit
       employees, or 2) the reduction of hours of bargaining unit employees
       below 40 hours a week; or 3)
       reduction of employees to a lower rated classification.
       It is understood that layoffs attributable to such things as inventory
       or production adjustments, changes in methods, processes or
       technologies, and/or break downs or failure of equipment power failure
       or any conditions beyond the control of the Company, are specifically
       exempted from this commitment.

(d)    Further, (a), (b) and (c) above does not apply to new construction or to
       construction involved in major modification work.

(e)    The Company agrees to notify the Local Union in writing with a copy to
       the  International or District Representative who services the Local
       Union, sent by registered mail, at least fourteen (14) days in advance
       if reasonably possible, and to meet with the Union, upon request by the
       Union, for explanation of the reasons causing the Company to decide to
       contract any production and maintenance work. The parties agree that
       while notification is an important part of the working relationship
       between the parties and should be adhered to in order to reduce the
       number of disputes concerning sub-contracting the parties also recognize
       and agree that this Section of the Contract does not require any penalty
       when the Company fails to give proper written notice of its intention to
       sub-contract.

       packaged products.

(b)    All basic, supplemental, pension, S.U.B. and insurance agreements will

       Company will provide each local with a supply of the booklets. The
       Company will print all Agreement booklets in large and legible type.

(c)    If the Union alleges that a Leadman or Temporary Foreman is exceeding or
       abusing his authority or that his actions violate the Contract, the
       Union may grieve their allegations directly to the Plant Manager. The
       Company will notify the employees involved whenever a Leadman or
       Temporary Foreman is being assigned.


                                  ARTICLE XVI

                               TERM OF AGREEMENT

(a)    This Agreement shall be binding upon the parties hereto, their
       successors, administrators, executors and assigns. In the event of the
       sale or lease by the Company of any of the plants covered by this
       Agreement, or in the event the Company is taken over by sale, lease,
       assignment, receivership or bankruptcy proceeding, such operations shall
       continue to be subject to the terms and conditions of this Agreement for
       the life thereof.

       The Company will notify the Union immediately prior to any Company press
       release concerning the intended sale or completed sale of a Plant.

       The Company shall give notice of the existence of this Agreement to any
       purchaser, lessee or assignee of said plant. Such notice shall be in
       writing with a copy to the Union not later than the effective date of
       the sale.

(b)    After ratification by the members of the Local Unions this Agreement
       shall become effective and remain in full force and effect and be
       binding upon the parties hereto from the date ratification is certified

       this Agreement, at any time thereafter upon notice.

Dear Mr. Clavier:

This letter will confirm that the Company has not entered into any secret
agreements with any sub-contractors for the purpose of making reductions in
employment at the plants nor does it have any plan to enter into any agreements
the effect of which would be in violation of the sub-contracting clause of the
labor agreement.

Sincerely,



Peter H. Geis
Corporate Director of

                             AGREEMENT AND PURPOSE
                                (B.A. Article 1)

                                   ARTICLE II

                         UNION RECOGNITION AND SECURITY
                               (B.A. Article II)

(a)    The Company is willing at all times to meet its employees' committee and
       representatives of the International Union for the purpose of discussing
       wages, hours, and working conditions, with the object to reach a
       satisfactory agreement.

(b)    The committee shall consist of not more than five (5) and not less than
       three (3) members.

(c)    Union dues will be deducted as close as the system permits, from the
       weekly paycheck after the first full week of the month for that given
       month. The Personnel Clerk will cooperate with the Financial Secretary
       of the Union if individual collection problems arise.

                                  ARTICLE III

                                   MANAGEMENT

(a)    The Union agrees to recognize the Company's right to manage its plant
       and direct its working force except as specifically limited by the terms

                                   SENIORITY
                               (B.A. Article III)

(a)    Any employee detained from work on account of sickness or for any other
       good reason shall notify the Plant Manager or his Foreman, before the
       start of his shift. Any employees absenting themselves from work for
       five (5) consecutive days without good and satisfactory reasons may be
       discharged and dropped from the seniority list and payroll of the
       Company. Repeated absence of less than five (5) days shall be subject to
       a progressive disciplinary program, and the Local Union will receive
       communications pertaining to each step disciplinary action within one
       working day excluding Saturdays, Sundays, and holidays of any action
       taken.

(b)    Subject to the approval of the Company, employees requesting a leave of
       absence in writing for personal reasons may be granted leaves of absence
       not to exceed thirty (30) calendar days.

                                   ARTICLE V

                           EMPLOYMENT AND PROMOTIONS

(a)    When considering  applicants for a vacant job pursuant to Article IV
       Section (h) of the Basic Agreement, an employee who has previously held
       and worked on a job permanently for one year or more in the THREE years
       prior to the bid in question shall have preference over an employee who
       has not previously held that bid job. When the Company elects to award a
       job to an applicant who will require training to satisfactorily perform
       the work, the employee to whom the job was awarded will receive the rate
       of pay for the job he previously held or the rate of pay for the job he
       was awarded,  whichever is less. It is understood that when the Company
       trains an employee, the employee in training will not work in place of
       an employee  whose job is the same as the employee in training. When an
       employee's  training is completed, the employee will be paid the rate of
       the job he was  awarded. This section does not apply to an employee who
       bids for a maintenance job.


                                   ARTICLE Vl

                               WORKING CONDITIONS
                                (B.A. Article V)

(a)    In accordance with Article (V)(h)(2) of the Basic Agreement overtime in
       the various job classifications will be reasonably equally divided among
       the employees of the respective job classification insofar as it is
       practical to do so.

(b)    Temporary Job Vacancies: The Company shall not be required to fill
       temporary job vacancies, whether scheduled or unscheduled, unless the
       efficient operation of the plant requires that said temporary job
       vacancies be filled.

(c)    When the Company determines that a temporary vacancy, scheduled or
       unscheduled, is to be filled by a laborer, the assignment will be made
       in the best interest of the efficient 


                                     44
<PAGE>   45

       operation of the Plant. In many instances, the company will offer the
       senior laborer an upgrade to higher rated classifications and will
       continue to do so depending on the circumstances, but not as a
       contractual requirement. However, if the Union determines that a
       repeated pattern and Practice of ignoring seniority on upgrades has
       developed concerning a particular individual or group of individuals, it
       may grieve such allegation directly to the Plant Manager.

       If the Union determines that evidence indicates that the Company is
       pre-training certain laborers so that employees are being
       discriminatorily selected for a particular job opening, it may present
       this allegation in the form of a grievance which will commence at the
       third step of the grievance procedure.

       Experience gained in a temporary job assigned or awarded in accordance
       with this Section shall not be considered in the awarding of any job.
       This Section does not alter or change the terms and provisions of
       Section (b).

(d)    The Normal schedule for day shift laboratory employees shall be 7:00
       A.M. to 3:00 P.M. with a paid lunch period. This agreement does not
       limit the Company's right to change schedules under the scheduling
       clause.

(e)    The Company is willing to post changes in an employee's schedule if it
       changed after the Thursday posting. The parties recognize that this is
       for information purposes only, there are no time requirements and that
       no penalties are required if such posting does not take place.

(f)    The Company will ensure that only properly trained individuals are 
       assigned to operate the Mobile Crane.

(g)    Under normal circumstances, if the Company requires an employee in the
       Quarry to go to the Plant to obtain parts or supplies, it will provide
       transportation to and from the Plant.


                                  ARTICLE VII

                               VACATIONS WITH PAY
                               (B.A. Article Vl)

(a)    In accordance with Article Vl(a) of the Basic Agreement any employee who
       works during at least thirteen (13) weeks in each calendar year shall be
       granted vacation off work without loss of pay, according to the schedule
       in Section (b) of Article Vl of the Basic Agreement.

(b)    The Company shall submit appropriate application blanks to the employee
       within the first week of the calendar year, and they are to be returned
       to the Company within one month. In the event an employee fails to
       return this form to the Company, then after this one month period, the
       Company shall designate the employee's vacation period, and notify the
       employee who fails to return this application to the Company and the
       Union of the vacation period designated for the employee. All vacation
       blanks received from employees or issued by the Company shall be
       returned to the employees not later than the first week in March.



                                     45
<PAGE>   46

(c)      Any change in an employee's selected and designated vacation period
         must be approved by the Company and the Union Committee.

(d)      (1)  Employees entitled to two (2) or more weeks of vacation may
              be permitted to take such vacations in two (2) separate periods
              of not less than one (1) week each. Seniority preference, however
              can be exercised in only one (1) such vacation period.

         (2)  At the option of the employee, one week of his vacation may be
              taken in single days, provided that he states his intentions when
              selecting his vacation at the start of the calendar year.

              When making the final selection of the single vacation days, the
              employee shall give as much notice as possible but not less than
              72 hours and request approval by the Plant Manager to take the
              vacation days chosen. This request shall not be unreasonably
              withheld.

              If an employee's schedule is changed after the Thursday posting
              as a result of another employee taking a vacation day one day at
              a time, there shall be no schedule penalty paid to such employee.

(e)    Vacations shall be taken within the calendar year in which it is granted.

(f)    Employees who have one (1) or more years of service and who are
       separated from service for any reason will receive vacation pay due them
       on the following basis: One-twelfth (1/12) vacation credit for each one
       hundred (100) hours worked in his current calendar year.

(g)    In the event the employment of any such employee is terminated for any
       reason, the Company shall pay to the employee, or to his beneficiary in
       the event of his death, all vacation due.

(h)    THE BALANCE OF AN EMPLOYEE'S SINGLE DAY VACATION WHICH IS NOT SCHEDULED
       AND APPROVED BY SEPTEMBER 1 OF EACH YEAR WILL BE SCHEDULED BY MANAGEMENT.

Dear Mr. Oleksy:

The following understanding has been agreed to by the Company and the Local
Union:

                   PROCEDURE FOR OVERTIME-CHARGING OF REFUSAL

1.     A weekly overtime list will be posted as a guide to equally divide
       overtime in the respective job classifications.

2.     Under normal circumstances all calls for callouts shall be verified by a
       bargaining unit member.

3.     Overtime will be charged as long as contact is made at the employees 
       home.

4.     Refused overtime will be charged at 1 X's the time worked or paid,
       whichever is greater. If an employee has no phone, he will be charged as
       if refused. Grievance pay in regards to OT, foreman working, etc., will
       be charged as overtime worked.

5.     Refused overtime is not to be charged when an employee is on vacation,
       on sick & accident, workmen's compensation, on funeral leave, or leave
       of absence.

6.     Overtime refused once in a 24-hour period does not mean the employee has
       refused all overtime for that period. Contacts or callouts will not be
       made in less than four (4) hour intervals.

7.     When an employee returns to work after being off on S & A or Workmen's

       lowest man in the classification. Leave of absence, etc.

Mr. August Clavier
UNITED CEMENT, LIME, GYPSUM AND
ALLIED WORKERS INTERNATIONAL UNION
Alpena, Michigan 49707

Dear Mr. Clavier

This letter is to confirm the Company's position and action taken by the
parties at our meeting with Local 480 at our Charlevoix Plant on March 25,
1980.

                      GRIEVANCES SCHEDULED FOR ARBITRATION

GRIEVANCE #47-78 - When the Company determines that it is necessary to require
an employee or employees in a classification to work overtime, it will go to
the qualified employee lowest in overtime in the classification who has not
voluntarily accepted that overtime, who is present in the plant. If sufficient
manning is not obtained at the Plant for the overtime required, the Company
will go to the employee lowest in overtime in the classification who is off, to
work the required overtime.

As circumstances permit, the Company will go outside the classification to
attempt to obtain another qualified employee before requiring an employee in
the classification to work overtime.

In the settlement of the grievance, the Company will reduce the three-day
disciplinary layoff to one day and the two applicable grievants will be paid
sixteen (16) hours at straight time.

Sincerely,



Peter H. Geis
Director of Labor Relations & E.E.O.

                                CHARLEVOIX PLANT

Should the Machinist classification be in a position where there is only one
person in the classification and he has not completed the Maintenance
Progression Program, and the Company determines another person should be added
to the classification, it will take the following steps:

1.     It will post for a Machinist "A" and will review those who bid on the
       job. If no one is qualified to fill the duties of a Machinist "A" then,

2.     The Company may hire a Machinist "A" to fill the position.

The parties recognize that this is an exception to the current terms of the
Maintenance Progression Agreement and is without precedence for any future
situations in any other classification covered by that Agreement.

                                   ARTICLE I

                             AGREEMENT AND PURPOSE


(a)    This Agreement is by and between Medusa Cement Company, a Division of

       Lime, Gypsum and Allied Workers Division (International Brotherhood of
       Boilermakers, Iron Ship Builders, Blacksmiths, Forgers and Helpers,
       AFL-CIO), hereinafter called the "Union", acting on behalf of its Local
       Union, whose members are employees of Medusa Cement Company.

(b)    The Company and the Local Union at each plant have negotiated a Local
       Agreement. Each Local Agreement has the same effective date and the same
       expiration date as this Basic Agreement. Local Supplemental Agreements
       shall not conflict or serve to modify provisions of this Basic
       Agreement.

(c)    It is the policy of the Company and the Union that the provisions of
       Agreement shall be applied to all employees without regard to race,
       color, sex, age, religious creed, national origin, handicap or Vietnam
       Era Veteran status.

       The Masculine words "he", "his" and "him" as used in this Agreement also
       shall mean the feminine words, "she" and "her".

                                   ARTICLE II

                         UNION RECOGNITION AND SECURITY

(a)    The Company recognizes the Union as the exclusive representative for all
       hourly rated production, maintenance, quarry and laboratory employees,
       excluding all office employees and all supervisors as defined by the
       National Labor Relations Act, as amended, for the purposes of collective
       bargaining in respect to wages, hours and working conditions at its
       plants located at:

                         Clinchfield, Georgia, Local D23

(b)    It shall be a condition of employment that all employees of the Company
       covered by this Agreement who are members of the Union in good standing
       on the execution date of this Agreement shall remain members in good
       standing and those who are not members in good standing on the execution
       date of this Agreement shall on the thirtieth (30th) day following the
       execution date of this Agreement become and remain members in good
       standing in the Union. It shall also be a condition of employment that
       all employees covered by this Agreement and hired on or after its
       execution date shall on the thirtieth (30th) day following the beginning
       of such employment become and remain members in good standing in the
       Union. (Because of State law, the above does not apply to Local D23 at
       Clinchfield, Georgia).

(c)    The term "employee" as used in this Agreement refers only to an employee
       whose job is set forth in the Job Classification list attached to each
       Local Agreement or any subsequent job added to the list during the term
       of the Agreement.

(d)    The Company will deduct from the monthly earnings of any of its
       employees his Initiation Fee and Union Membership Dues and will pay the
       same to the party to whom such employee directs the Company in writing.
       Each such employee desiring such deduction to be made from his earnings
       must present to the Company his signed order, which shall be
       substantially as follows:

       "I hereby authorize and direct the Medusa Cement Company to deduct and
       pay from my earnings accumulated to my credit my Initiation Fee and Union
       Membership Dues, and pay same to ............ I further agree to hold the
       Medusa Cement Company harmless on account of deductions and payment
       herein authorized."

       This authorization may be canceled by the Union member on any
       anniversary date of this Agreement upon thirty (30) days prior written
       notice to the Company and the Union.

(e)    The union shall furnish to the Plant Manager a written list of the names
       of employees who will serve on the committee. The number of employees on
       the committee shall be defined by each Local Agreement. If a vacancy
       occurs on the committee, the Plant Manager, shall be informed by letter
       of the name of the new member before a meeting is held. No other members
       of the Union who are employees at the Plants are eligible to attend
       these meetings unless previously agreed to by the parties hereto.

(f)    Notwithstanding the provisions of Article II (b) above, any employee, who
       is a member of and adheres to established and traditional tenets or
       teachings of a bona fide religion, body or sect which has historically
       held conscientious objections to joining or financially supporting labor
       organizations shall not be required to join or financially support the
       Union as a condition of employment; provided, however, that each such
       employee shall, as a condition of his or her employment, in lieu of the
       payment of periodic dues and initiation fees to the Union, pay sums equal
       to such dues and initiation fees to any one of the following nonreligious
       charitable funds, which are exempt from taxation under Section 501(C)(3)
       of the Internal Revenue Code:

                  1.     City of Hope
                  2.     American Cancer Society
                  3.     American Heart Association
                  4.     National Multiple Sclerosis Society
                  5.     American Red Cross

       It is expressly understood that any such employee holding conscientious
       objections and choosing not to join or financially support the Union,
       who requests the Union to use the grievance arbitration procedure on the
       employee's behalf, shall be required to pay to the Union the reasonable
       cost of processing any grievance on his or her behalf including
       reasonable cost of arbitration if any. (Because of State law this does
       not apply to Local D23 at Clinchfield, Georgia.)

(g)    Upon receipt from an employee authorizing payroll deduction and
       specifying the amount to be deducted, the Company will deduct voluntary
       contribution to the City of Hope. All amounts so deducted shall be
       remitted by the Company to the City of Hope.

       The Company shall be held harmless from any claim, demand or action
       arising out of such deductions.

       Employees contributing to the City of Hope cannot discontinue or change
       such contributions for one year.

                                  ARTICLE III

                                   SENIORITY

(a)    The seniority unit shall be plant-wide.

(b)    Seniority is continuous service which shall be calculated from date of
       first employment or re-employment following a break in continuous
       service, whichever occurs later.

       When two or more employees are hired on the same day, the employee with
       the lowest last four (4) digits in their social security number shall be
       senior to the employee with the highest last four (4) digits. This
       paragraph is effective May 10, 1978.

(c)    New employees and those hired after a break in continuity of service
       will be regarded as probationary employees for the first sixty (60) days
       of work and will receive no continuous service credit during such
       period. Probationary employees may file and process grievances under
       this Agreement, but may be laid off or discharged as exclusively
       determined by the Company. Probationary employees who continue in the
       service of the Company subsequent to the first sixty (60) days of work
       shall receive full continuous service credit from date of the most
       recent hiring. (PROBATIONARY PERIOD MAY BE INCREASED THIRTY (30)
       ADDITIONAL WORK DAYS SUBJECT TO APPROVAL BY THE UNION.)

(d)    An employee covered by this Agreement shall lose his entire seniority if:

       (1)    He voluntarily quits;

       (2)    He is discharged for cause and not rehired within six (6) months
              or reinstated;

       (3)    An employee's seniority shall be broken and his employment
              terminated effective on date of his acceptance of Termination
              benefits under the provisions of the Supplemental Unemployment
              Benefit Plan Agreement;

       (4)    The employee is on layoff or disability for a period of three
              years or 50% of his seniority attained at the start of such
              absence, whichever is less.

(e)    A leave of absence for the purpose of accepting a position with The
       Cement, Lime, Gypsum and Allied Workers Division at the Local, district,
       or international level, or the AFL-CIO or any of its subordinate bodies,
       shall be available to not more than three (3) employees from each plant
       at any one time. Applications for such leave shall be submitted to the
       Company in writing thirty (30) days prior to the effective date of such
       leave to permit proper provisions to be made to fill the job to be
       vacated. Leaves of absence for this purpose shall be for an indefinite
       period. During such leave, seniority shall accumulate. Group insurance
       coverage shall be suspended after thirty (30) days of such leave.

       All insurance coverages will be reinstated upon returning to work with
       the Company. Upon returning to work such employee will be reinstated on
       his former job, providing it is 


                                       6
<PAGE>   7

       still in existence; if not, he shall be eligible to apply for any job
       within the bargaining unit by means of the existing bidding procedure or
       by bumping.


(f)    The Company shall attach to each Local Agreement a list of employee's
       seniority dates in order of hiring and a list of the probationary
       employees.

(g)    Temporary summer employees may be employed by the Company from May 1st
       through September 30th in order to facilitate filling of vacancies
       caused by vacations during these months. Employment of summer employees
       will be subject to the following conditions:

       (1)    No summer employee will be hired when any regular employee is on
              layoff or drawing short workweek benefits.

       (2)    All summer employees will be required to join the Union under the
              same terms and conditions as required in Article II, Sections (b)
              and (d) of the Basic Agreement.

       (3)    All summer employees must sign an appropriate form which will
              spell out the terms of their employment including but not limited
              to an agreement to commence their employment on a specified date
              and terminate their employment on a specified date. Such dates
              must be in accordance with the time period specified in this
              section.

       (4)    The term of employment will not be changed, altered or extended
              unless mutually agreed to by both the Company and the Local Union
              Committee.

       (5)    Summer employees shall not accumulate seniority nor be eligible
              to bid on any new job or vacant job which may occur during their
              terms of employment.

       (6)    A summer employee will not become eligible for a floating holiday
              and will not have any vacation rights.

       (7)    Summer employees will not participate in the Company's pension,
              S.U.B. and insurance programs.

       The above will be in full force and effect, except that if any portion
       is found to be contrary to any federal, state or local law, it shall be
       changed to comply with said law.

                                   ARTICLE IV

                                  JOB SECURITY

(a)    (1)    Whenever the installation of mechanical equipment, change in
              production methods, the installation of new or larger equipment,
              the combining of jobs or the elimination of jobs, will have an
              effect on the job status of one or more employees, the Company
              will give the Union reasonable advance notice of same and, upon
              request by the Union, will promptly meet with the Union to review
              and explore the effects of such installation or installations or
              change or changes upon the working force.


                                       7
<PAGE>   8

       (2)    Employees will not be terminated by the Company as the result of
              mechanization, automation, change in production methods, the
              installation of new or larger equipment, the combining of jobs or
              the elimination of jobs.


       (3)    Whenever an employee is no longer needed on his regular job as a
              result of circumstances described in (1) above, such employee may
              apply for any job or jobs within the bargaining unit on which an
              incumbent has less seniority, and for which he could reasonably
              be expected to qualify within a ninety (90) day on-the-job
              training period unless the employee applying for such job is
              disqualified due to physical reasons.

              The rate of pay for such employee shall not be less than
              ninety-five percent (95%) of the rate for the regular job from
              which he was displaced, irrespective of the rate of the job which
              he applies for and obtains.

              The ninety-five percent (95%) of rate protection shall apply for
              a minimum period of one (1) year, or a period equal to one-third
              (1/3) of an employee's seniority up to a maximum of two (2)
              years. If the affected employee is tendered training for a job
              which he could be reasonably expected to qualify for with a
              ninety (90) day on-the-job training period and refuses, he will
              not be entitled to any rate protection unless he has a bona fide
              reason for refusing. If an employee on ninety-five (95%) percent
              rate protection subsequently bids on and is awarded a lower rated
              job, he shall lose his rate protection.

       (4)    Employees affected by the application of the foregoing procedures
              shall have and may exercise the same rights for retention and
              on-the-job training in accordance with their seniority status and
              the ninety-five percent (95%) rate guarantee shall also be
              applicable to them.

       (5)    Employees who do not apply for and/or obtain a job in accordance
              with the provisions of (3), including employees displaced from
              their jobs but whose seniority status does not permit them to
              utilize job retention rights under the provisions of (3) or (4)
              will be placed on layoff status with recall rights in line with
              their seniority status for job vacancies which may thereafter
              occur.

       (6)    The provisions of (3) of this Section do not apply to
              displacements or layoffs resulting from production curtailments,
              except that employees laid off and not recalled when production
              is resumed following curtailment will be entitled to the same
              rights as employees affected by the preceding (3).

       (7)    Should the Company permanently shutdown the present facilities
              affording employment to the employees comprising the bargaining
              unit (the present facilities shall be deemed to have been
              permanently shutdown if all productive facilities are abandoned
              even though the shipping facilities continue to operate), the
              Company shall mail a notice informing each affected employee that
              his employment with the Company has been terminated because of
              the permanent shutdown. The notice shall be mailed at least
              ninety (90) days prior to the shutdown to the employee's last


                                       8
<PAGE>   9

              address on the Company's records. Each employee who is mailed
              said notice shall have the following options:


       A.     An employee who is not eligible for a normal (excluding thirty
              (30) year retirement pension) or late retirement pension may
              elect to transfer to another operation of the Company covered by
              a collective bargaining agreement with the Union in accordance
              with paragraph 8 or paragraph 9.

              Any transfer pursuant to paragraph 8 or 9 will occur not later
              than three (3) years after the last day the employee worked. An
              employee awaiting transfer shall be placed on layoff and shall
              receive S.U.B. Layoff or reduced layoff benefit provided the
              eligibility and other requirements of the S.U.B. Plan are met. An
              employee may void

              his election to transfer at any time during the three (3) year
              period. If the employee is eligible for an immediate pension at
              the time he voids his election to transfer, he shall retire,
              effective the date he voids his election, under the pension plan
              in effect at the time of the permanent shutdown. An employee may
              also void his election in order to apply for S.U.B. Termination
              benefits.

       B.     An employee who is eligible for an immediate pension at the date
              of the permanent shutdown shall retire as of the effective date
              of the permanent shutdown, except

              1.    An employee whose combined age and years of service equal
                    62 or more but less than 65 may elect layoff until his
                    combined age and years of service equal 65 at which time
                    the employee shall retire and receive a permanent shutdown
                    pension. The pension plan in effect at the time of the
                    permanent shutdown shall determine the retirement benefits
                    payable to the employee. An employee who elects layoff
                    under these conditions shall receive S.U.B. Layoff or
                    reduced layoff benefits provided the eligibility and other
                    requirements of the S.U.B. Plan are met.

              2.    An employee who is eligible for an immediate pension other
                    than a normal or late retirement pension and who elects to
                    transfer to another operation of the Company shall not
                    retire unless the transfer is not accomplished.

              3.    An employee shall not be required to retire under a
                    disability retirement pension earlier than he would
                    otherwise be required to retire if the Company had not
                    permanently shut down the facilities.

              An employee who retires under the Pension Plan may also be
              entitled to receive S.U.B. Terminations benefits in accordance
              with the terms of the S.U.B. Plan.

       C.     The employee may elect S.U.B. Termination Benefits in accordance
              with the terms of the S.U.B. Plan at any time within one (1) year
              after notice of termination has been mailed to him.



                                       9
<PAGE>   10

              An employee other than an employee who is eligible for an
              immediate pension may elect layoff prior to submitting his
              application for S.U.B. Termination Benefits and shall receive
              S.U.B. Layoff or reduced layoff benefits provided the eligibility
              and other requirements of the S.U.B. Plan are met.



       D.     If the facilities which have been permanently shut down are
              reopened by the Company within three (3) years of the date of the
              permanent shutdown, an employee who has retired under the Pension
              Plan shall be eligible for recall in accordance with his seniority
              status at the time of the permanent shutdown. An employee who has
              elected S.U.B. Termination benefits shall also be eligible for
              recall in accordance with his seniority status at the time of the
              permanent shutdown. Any pensioner who has received S.U.B.
              Termination benefits and accepts recall and any former employee
              who has received S.U.B. Termination benefits and accepts recall
              shall repay said Termination benefits to the S.U.B. Trust Fund or
              to the Company, whichever was the source of the Termination
              benefits, in accordance with the S.U.B. Plan Agreement. Any
              employee who accepts recall shall have his previously accumulated
              seniority rights, pension, S.U.B., insurance and vacation credits
              as of the last day the employee worked or at the date of permanent
              shutdown, whichever occurs later, reinstated on the date he
              returns to work.

       E.     An employee who is not eligible for an immediate pension may
              elect layoff and shall receive S.U.B. Layoff or reduced layoff
              benefits provided the eligibility and other requirements of the
              S.U.B.
              Plan are met.

              The employment rights of any employee on layoff shall terminate
              three (3) years after the last day the employee worked and the
              employee's seniority shall be broken.

       F.     An employee's participation in the group insurance program shall
              terminate effective the day following the last day the employee
              worked and pending claims shall be processed in accordance with
              the terms of the existing group insurance program. No employee
              shall be eligible for holiday pay or vacation pay other than
              vacation pay due after the last day the employee worked or the
              date of the permanent shutdown, whichever occurs later. No
              employee shall accumulate credited service under the pension plan
              after the last day the employee worked or the date of the
              permanent shutdown, whichever occurs later.

     (8)      In the event the Company constructs a new plant that will affect
              the employment status of employees in the Company's plant or
              plants comprising a bargaining unit, such employees shall be
              given an opportunity to make application for employment in the
              new plant before it starts operation, and such employees shall be
              given preferential employment right for the highest rated job the
              employee is capable of performing. Such an employee shall
              transfer with him all of his previously accumulated pension,
              S.U.B., insurance and vacation credits. His seniority rights at
              the former plant shall terminate upon his establishment of
              seniority rights in the new plant.



                                       10
<PAGE>   11

     (9)      When an employee has been laid off or displaced because of
              permanent changes in the working force or because of a plant
              closing, he may make written application within fifteen (15) days
              of layoff or displacement for employment in another plant of the
              Company, and he shall be given preferential employment rights for
              job openings at such other plant, providing such employee is
              capable of performing the job that may be available at such other
              plant of the Company. Any employee so transferring from one plant
              to another of the Company shall retain his previously accumulated
              pension, S.U.B., insurance and vacation credits. His seniority
              rights at the former plant shall terminate upon his establishment
              of seniority rights in the plant to which he transferred.

     (10)     Employees transferring from one plant to another as provided in
              (a) (7), (8) and (9) of this Article will receive a moving
              expense allowance. The Company will reimburse each employee for
              actual moving expenses incurred to move furniture and other
              household goods up to a maximum of $1,000 per employee.

(b)    When a production curtailment or a plant shutdown causes a reduction in
       personnel in a department or throughout the plant, a senior employee
       whose regular job is not required shall have the option of accepting
       available work for which he is qualified or accepting layoff. A Senior
       employee who elects to accept available work shall be entitled to:

       (1)    Bump any junior employee whose job was previously held by the
              senior employee on a permanent basis for a sufficient period of
              time to demonstrate his ability to satisfactorily perform the job
              as it is constituted at the time of the production curtailment or
              plant shutdown. The senior employee must attempt to bump into a
              job that he previously held in the reverse order of his
              promotions. In other words, he must first attempt to bump into
              the job he held immediately prior to his present job, except each
              employee may select one job that he had previously held on a
              permanent basis or is qualified to perform immediately, and for
              purposes of this section only, consider it to be the job he held
              immediately prior to his present job. Each employee may make such
              selection and this selection shall be updated effective on May 1,
              of each contract year at the employee's discretion.

              If the above procedure would result in an employee becoming a
              part of the labor crew, he may exercise his bumping rights set
              forth in (2) prior to entering the labor crew.

       (2)    An employee can bump a junior employee on a plant-wide basis
              except for any maintenance job, any laboratory job, or those in
              the control room operator classification, provided he is
              qualified to perform the job immediately.

              Employees who hold utility or vacation-relief jobs where the
              employee actually works on several different jobs on a scheduled
              basis shall be considered as having held those classifications on
              a permanent basis for purposes of this section (b).

              Any junior employee who is displaced by a senior employee shall
              have the same rights as the senior employee set forth herein.

                                       11
<PAGE>   12

              After the bumping is completed, the Company has the right to
              require a senior employee to perform available work during the
              curtailment or shutdown if there is no junior employee with the
              necessary qualifications to perform the work.

              A plant shutdown is defined as a period during which none of the
              clinker burning units are producing.

              The wage rate paid during a production curtailment shall be the
              wage rate of the job performed. An employee who works on two or
              more jobs in one day shall be paid in accordance with Article V
              (j) (2).


              During periods of plant shutdowns when employees are needed for
              maintenance, repairs or work on plant alterations, the wage rate
              paid to employees who are retained for work during the first
              forty-five (45) days of plant shutdown shall not be less than the
              employee's regular straight time wage rate normally paid when the
              plant is producing. After forty-five (45) days, the wage rate
              paid shall be the wage rate of the job performed. An employee who
              works on two or more jobs in one day shall be paid in accordance
              with Article V (j) (2).

              The ninety-five (95%) percent rate protection is not applicable to
              any bumping under this procedure.

(c)    When the Company determines that additional jobs are required during or
       following a production curtailment or a plant shutdown in order to
       maintain or increase the work force, the manner in which the reduction
       of forces took place pursuant to Article IV, Section (b) will be
       reversed.

       In the event that during a production curtailment or a plant shutdown an
       employee bids for and is awarded another job, he shall lose all rights
       pertaining to the job the employee previously held.

       Sections (b) and (c) of Article IV shall not add to, subtract from, or
       otherwise modify any maintenance training agreement by and between the
       Company and the International and/or Local Unions negotiated before or
       after the effective date of this Basic Agreement.

(d)    The Company agrees to post a notice at least one week in advance of an
       intended shutdown. Whenever a layoff is planned because of a change or
       reduction in plant production requirements, the Company will, not less
       than seven (7) calendar days prior to the effective date of the layoff,
       post a bulletin stating the expected extent of such layoff, and the
       expected effect on the work force. In the event the required notice is
       not given in accordance with the above, the Company will pay the laid off
       employee(s) the scheduled time lost at the applicable straight-time
       hourly rate. The seven (7) calendar day period shall commence on the
       completion of the third shift following the day in which the notice was
       posted. The foregoing does not apply to disciplinary layoffs and layoffs
       because of curtailment made necessary by disaster or emergency conditions
       affecting the ability of the Company to physically operate the plant.



                                       12
<PAGE>   13

(e)    Company personnel excluded from the bargaining unit shall not regularly
       perform bargaining unit work except temporarily in an emergency; for
       training or instruction purposes, for testing, diagnosis, analysis or
       when necessary to prevent disruption of the flow of operations or when
       necessary to meet the interest of efficient operations.

       Should a Company person excluded from the bargaining unit violate this
       commitment the Company will be required to pay to the effected worker or
       workers double time (his or their) regular straight time hourly rate for
       anytime worked by person not included in the bargaining unit, with a
       minimum of four (4) hours pay. If there is no affected worker, the
       penalty for such work shall be paid to the worker lowest in overtime in
       the classification and/or department.



(f)    Any employee who becomes incapacitated and on the basis of competent
       medical opinion cannot perform the duties of his/her regular job may
       exercise his/her plant seniority through the bumping procedure to move
       to any position within the bargaining unit at the plant for which he/she
       could qualify within a reasonable period of time but not to exceed 90
       days. This in no way affects the bidding right of the employee.

(g)    Any employee who is displaced by an incapacitated employee pursuant to
       paragraph (f) of this section, may exercise his/her plant seniority to
       bump into another position within the bargaining unit at the plant for
       which he/she is qualified in the same manner as covered in the job
       bidding procedure. The 95% rate protection is not applicable to bumping
       under paragraphs (f) and (g).

(h)    All vacancies and new jobs created shall be posted no later than the
       eighth day following the date the vacancy occurred or the new job was
       created. Said vacancies and new jobs shall be posted for seven (7) days
       to allow any employee to make application in writing for such job. The
       Company will consider every application in terms of:

       (1 )   Seniority

       (2)    The applicant's skill and ability and physical fitness measured
              against the requirements of the job.

              Where two or more applicants' qualifications in (2) are relatively
              the same, seniority shall govern.

              If an employee proves unsatisfactory, he shall be reinstated to
              his previous job. An employee who bids for and is awarded a job,
              excluding any employee who is disqualified subsequent to the
              award, may not bid any job in the same or lower bracket for six
              (6) months from the date he was awarded his new job without the
              consent of the Company; except that an employee may bid from an
              operating job to a maintenance job or a laboratory job, from a
              maintenance job to an operating job or a laboratory job, or from
              a laboratory job to an operating job or a maintenance job even
              though the employee is bidding a job in the same or lower bracket
              within six (6) months.



                                       13
<PAGE>   14

              This Section does not require the Company to award a job to any
              applicant if no applicants are qualified to perform the work.

              The Company has the right to assign any employee to fill a new
              job or to fill a vacancy until the job has been awarded.

              The Company will meet with the Local Union Committee to explain
              its decision when the Company awards a job to a junior applicant.
              Any senior applicant shall have the right to challenge the
              Company's award by filing a grievance in a timely manner. Any
              employee reinstated to his previous job shall have the right to
              challenge his disqualification by filing a grievance in a timely
              manner.



       (3)    Once a job has been awarded, the Company will make every effort
              to place the successful bidder on the job as soon as possible,
              but within thirty (30) calendar days from the date of the job
              award. Should the Company fail to place the successful applicant
              on the job in the 30 day period, the applicant shall receive the
              rate of pay for the new job commencing with the 31st day, until
              such time as he is placed on the new job. At that time, he will
              be paid in accordance with this Basic Agreement, Local
              Supplemental Agreement, or plant practice, whichever is
              applicable.

              This shall not apply if the delay beyond thirty (30) days is
              caused by multiple bidding to fill the original vacancy.

                                    ARTICLE V

                               WORKING CONDITIONS

       his new schedule and the premium shall be paid in addition to whatever
       compensation the employee is otherwise entitled to receive under any
       other Section of this Agreement. An employee's work schedule is changed
       and the premium is paid when the employee is required by a schedule
       posted after the first shift on the previous Thursday to work hours in
       place of the hours the employee was required to work by the schedule
       posted prior to the end of the first shift on the previous Thursday.

              worked immediately succeeding and in excess of such twelve (12)
              hours at double the regular straight time hourly rate.

              If an employee is being paid the rate of double time under the
              foregoing paragraphs, his rate of pay shall not be reduced when
              his work continues into or overlaps his regular shift. However,
              the Company may exercise either of the following options:


       A.     The Company may instruct the employee to continue to the end of
              the shift at the double time rate, or

       B.     The Company may send the employee home at any time during the
              shift, provided the remainder of the shift is paid for at
              straight time, subject to a maximum payment of four (4) hours at
              straight time. Such employee cannot be called back to work until
              he has been off duty for eight (8) consecutive hours.

              In no event shall the first two provisions of the Section be
              applied to the same hours of work. The provision which creates
              the highest earnings shall be applied.


       (3)    Callouts and Off-days: In case an employee is called for work
              during any hour in the day or week in addition to his regular
              schedule he shall receive a minimum of four (4) hours' pay for
              such work at the applicable overtime rate. However, if he is
              notified before the end of his regular shift to report early, it
              shall not be considered a callout. Callout hours and off-day
              hours are overtime hours. All Sunday callouts to be paid a
              minimum of four (4) hours at the applicable Sunday rate.

       (4)    Lunch period interrupted by work assignments: One-half (1/2) hour
              at the applicable overtime rate shall be paid for any scheduled
              lunch period interrupted by a work assignment and either prior or
              subsequent to the regular lunch period, reasonable time for lunch
              shall be granted with pay for same at the employee's regular
              rate.

       (5)    If an employee actually works seven consecutive workdays in the
              plant workweek, regardless of the number of hours worked on any
              workday, the employee shall be compensated by multiplying the
              regular straight-time hourly rate by one (1) for each and every
              hour worked during the seventh consecutive workday, and this
              premium shall be paid in addition to whatever compensation the
              employee is otherwise entitled to receive under any other Section
              of this Article.



                                       16
<PAGE>   17

(f)    Overtime paid on a daily basis shall not be duplicated on a weekly basis.

(g)    If an employee does not work a regularly scheduled workday through
       action of the Company, excused absence or because of a holiday, that day
       shall be considered as actually a day worked for all overtime purposes.

(h)    Limitations Upon Overtime:

       (1)    Every reasonable effort will be made by the Company to avoid
              requesting any employee to work overtime and the Company will
              consider under the circumstances involved any reasonable excuse
              from an employee for not working the overtime. Whenever an
              employee is laid off due to lack of work or because of
              curtailment of operations, no overtime work shall be scheduled on
              any work which the laid-off employee is capable of doing and is
              able to perform, except in cases of emergency repair or
              unscheduled absences of other employees. The foregoing to the
              contrary notwithstanding, a laid-off employee will not be called
              back to work unless there is at least thirty-two (32) hours work
              in the workweek for such employee.


       (2)    Overtime in the various job classifications shall be equally
              divided as defined by the Local Agreement insofar as it is
              practical to do so. Any employee who is contacted and cannot work
              the overtime including callouts will be charged with the number
              of hours actually worked or paid, whichever is greater or
              according to the Local Agreement. Overtime worked or charged
              shall be posted weekly in each department by the foreman.

       (3)    Employees who are called upon to work overtime shall not be laid
              off during their regular work time for the purpose of equalizing
              said overtime.

       (4)    The Company will continue its practice of allowing a fifteen
              minute paid wash-up time on continuous overtime beyond the end of
              his shift. In addition, the Company will continue its practice of
              paying overtime in fifteen (15) minute increments.

       (5)    A.     Any employee who has not been notified of his overtime
                     assignment at least twelve (12) hours prior to the
                     commencement of the overtime assignment and who works more
                     than ten (10) consecutive hours, shall be provided with a
                     hot lunch which shall be eaten at the end of said ten (10)
                     consecutive hours, or as soon as practical thereafter but
                     no later than 30 minutes after the ten hours. Any employee
                     who works in excess of fourteen (14) consecutive hours
                     shall be provided with an additional lunch, and lunches
                     will be furnished at the end of every four (4) consecutive
                     hours worked thereafter.

              B.     Any employee who is called out and works more than four (4)
                     consecutive hours shall be provided with a hot lunch which
                     shall be eaten at the end of said four (4) consecutive
                     hours. In addition, said employee shall be provided with a
                     hot lunch every four (4) consecutive hours worked
                     thereafter.



                                       17
<PAGE>   18

                     There shall be no duplication of hot lunches under
                     provisions A and B above. The employees shall be given
                     reasonable time to eat his lunch without loss of pay.

       (C)    THE COMPANY AGREES THAT THE ALLOWANCE FOR OVERTIME MEALS WILL BE
              INCREASED TO $6.00 EFFECTIVE MAY 1, 1998, TO $6.50 EFFECTIVE MAY
              1, 2000 AND TO $7.00 EFFECTIVE MAY 1, 2002.

       (6)    The purpose and intent of this Agreement is to refrain from
              working an employee beyond sixteen (16) consecutive hours
              excluding lunch periods. The Company agrees that they will not
              work any employee beyond sixteen (16) consecutive hours excluding
              lunch periods unless no other classified employee is available to
              do the work.

              However, in the event that a vacancy occurs that would require a
              classified employee to work more than sixteen (16) consecutive
              hours, the Company will fill that vacancy with another classified
              employee who has primary overtime rights, an employee with
              secondary overtime rights, or other qualified employee in the
              stated order.


              This Agreement does not absolve an employee from the requirement
              to stay on the job until properly relieved. However, the Company
              is required to make a diligent effort to provide a relief at the
              end of the sixteen (16) hour period. The Company will not use the
              eight (8) hour rest clause as an excuse to require an employee to
              continue working after sixteen (16) hours.

(i)    Eight Consecutive Hour Rest Premium


       (1)    An Employee should receive at least eight (8) consecutive hours
              off work within the fourteen (14) consecutive hours immediately
              preceding the start of his next scheduled shift. In the event an
              employee does not receive eight (8) consecutive hours off work
              within the fourteen (14) consecutive hours immediately preceding
              the start of his next scheduled shift, the Company shall exercise
              one of the following options:

              A.  Instruct the employee to report late for his next scheduled
                  shift by the number of hours his longest consecutive off-duty
                  period falls below eight (8) hours and pay the employee the
                  appropriate straight-time rate for those hours not worked
                  between the starting time of his scheduled shift and the time
                  he reports to work in accordance with the Company's
                  instructions. The appropriate straight time rate on the
                  workday Sunday shall be one and one-half (1.5) and on a
                  recognized holiday, two (2.0).

              B.  Instruct the employee to work at the starting time of his
                  scheduled shift. The employee shall receive a premium for
                  those hours worked which, if added to his longest consecutive
                  off-duty period, equal eight (8) hours. The premium shall be


                                       18
<PAGE>   19

                  determined by multiplying the regular straight-time hourly
                  rate by one (1). The premium shall be in addition to whatever
                  compensation the employee is otherwise entitled to receive
                  under any other Section of this Article.

       (2)    If an employee does not receive at least eight (8) consecutive
              hours off work within the fourteen (14) consecutive hours
              immediately preceding the start of callout hours worked on an
              off-day (provided that any of the callout hours worked occur
              within the hours the employee would have otherwise been scheduled
              to work had the employee not been scheduled off), the employee
              shall receive a premium for those hours worked which, if added to
              his longest consecutive off-duty period, equal eight (8) hours.
              The premium shall be determined by multiplying the regular
              straight time hourly rate by one (1). The premium shall be in
              addition to whatever compensation the employee is otherwise
              entitled to receive under any other section of this Article.



(j)    Wage Rate - Transfer and Assignments

       (1)    Employees temporarily transferred shall be paid the regular
              straight time hourly rate of the job being performed or the
              regular straight time hourly rate of his regular job, whichever
              is greater.


       (2)    An employee regularly scheduled to work on two or more jobs
              having different wage rates shall receive the highest rate for
              the entire week. If a job is regularly scheduled to be performed
              each week at least one workday in the workweek, the employee
              filling that job shall receive the highest wage rate for the
              entire week. An employee who is scheduled to work five workdays
              during the workweek on a job or jobs having a higher straight
              time hourly wage rate or wage rates than the employee's regular
              straight time hourly rate, shall be paid at the higher straight
              time hourly wage rate for the entire week. An employee who works
              on two or more jobs in one day shall receive the highest wage
              rate for only the time worked on the higher rated job. However,
              should the employee work on a higher rated job(s) for four (4) or
              more hours in the workday he will receive the higher rate of pay
              for the entire day. The term "entire week" used in this section
              shall mean the 168 consecutive hours beginning at 7:00 a.m. on
              Sunday and ending at 7:00 a.m. on Sunday. The term "entire day"
              used in this Section shall mean the 24 consecutive hours
              beginning at 7:00 a.m. and ending the following day.

              The 168 consecutive hours mentioned above shall begin at 7:00
              a.m. Monday and ending at 7:00 a.m. Monday, at Local D23,
              Clinchfield, Georgia.

       (3)    The Company shall have the right to utilize employees to perform
              any job; provided, however, overtime and callouts in any
              classification shall be offered to the available classified
              employees in that classification before other employees are
              assigned such work. See Attachment "B" for Letter of
              Understanding concerning transfers.



                                       19
<PAGE>   20

(k)    Sunday Work

       All hours worked by an employee on Sunday which are not paid for on a
       premium and/or overtime basis shall be paid at the rate of one and
       one-half (1-1/2) times the regular straight time hourly rate exclusive
       of shift differentials. There shall be no duplication or pyramiding of
       premium pay and/or overtime under this provision.

(l)    Reporting Pay

       Any employee who is required to report for work shall be given at least
       four (4) hours pay at the regular straight time hourly rate, and shall
       receive full pay for all time thereafter that he is required to remain
       on the premises ready for work. Any employee put to work on his regular
       working day shall receive full day's pay at the regular straight time
       hourly rate.

(m)    Funeral Leave

       An employee, upon the notification of the death of his or her father,
       mother, spouse, son, daughter, brother, sister, stepfather, stepmother,
       stepson, stepdaughter, half sister, half brother, mother-in-law,
       father-in-law, brother-in-law, sister-in-law, grandchild, grandparent,
       or spouse's grandparent, shall be granted his or her next three (3)
       scheduled working days off with pay (four (4) days off with pay if the
       employee is required to travel beyond a radius of 500 miles). Payment by
       the Company for such time lost shall be on the basis of eight (8) hours
       per day at the employee's regular straight time hourly rate, including
       shift differential.

       As used herein, brother-in-law is defined to mean (1) the brother of
       one's husband or wife, (2) the husband of one's sister, (3) the husband
       of the sister of one's spouse, and sister-in-law is defined to mean (1)
       the sister of one's husband or wife, (2) the wife of one's brother, (3)
       the wife of the brother of one's spouse.

       The above clause shall not apply to an employee who is laid off, except
       when an employee is notified to return to work effective on or before
       the day of the funeral he shall be granted full funeral leave with pay.

       The Company will notify a local union official of a death of an
       employee's relative as defined above as soon as the Company has been
       advised by the employee.

       The foregoing to the contrary notwithstanding, no bereavement payment
       will be made unless the employee attends the funeral nor will payment be
       made if there are more than fourteen calendar days between the date of
       death and the next scheduled workday.

(n)    Jury Duty

       Any regular employee (as distinguished from a probationary employee)
       required to perform jury duty on a day he is scheduled to work, shall be
       excused from work on that day. The Company shall pay the employee the
       difference between the amount received for such jury duty and eight (8)
       hours at his regular rate of pay plus shift differential if involved.



                                       20
<PAGE>   21

       The day or days paid for such jury service shall be counted as eight (8)
       hours worked for the purpose of computing weekly overtime.

(o)    Shift Changes

       A shift employee may clock in up to 30 minutes prior to the actual
       starting time of his shift and relieve the employee that he is to
       replace. When properly relieved within this 30 minute period, the
       employee being relieved may clock out and leave the plant.

       Under such circumstances the pay received by the relieving and relieved
       employees shall be computed as though both employees had clocked in and
       out at the actual shift change time.

(p)    Wash Time and Rest Breaks

       (1)    An employee who does not receive a paid lunch period shall not
              clock out prior to the regular quitting time for his shift.
              However, he shall be permitted to leave his place of work 15
              minutes prior to the regular quitting time for his shift to wash
              provided that the employee is not required to work overtime. An
              employee who does not receive 15 minutes away from the job to
              wash because he has been required by the Company to work up to
              but not after the regular quitting time for his shift, shall be
              compensated for lost wash time by multiplying his regular
              straight time hourly rate by fifteen minutes (.25 hour). If the
              employee uses additional time to clean following the regular
              quitting time for his shift, he shall be paid as though he had
              clocked out at the regular quitting time.


       (2)    An employee who does not receive a paid lunch period and who is
              required to work overtime after the regular quitting time for his
              shift shall clock out no more than 15 minutes after he leaves his
              place of work. This shall not apply to an employee on call out.

       (3)    An employee who does not receive a paid lunch period will be
              allowed a 15 minute rest break away from his job during the first
              four hours of his regular shift. Break times shall be determined
              by the employee's foreman and the efficient operation of the
              plant shall be controlling. The 15 minute break shall be strictly
              construed to be the total time away from the job. Should any
              employee regularly be denied a break, he may file a grievance in
              a timely manner.

       (4)    The Company is not required to grant any employee who does
              receive a paid lunch period any wash-up time and any rest break.
              Furthermore, said employee shall eat his lunch "on-the-job" so
              that there is no interruption of operations.

(q)    Any other provisions of this labor agreement to the contrary not
       withstanding, no employee shall receive pay for any hour worked or
       unworked which singly or in any combination, exceeds triple his regular
       straight time hourly rate.

                                   ARTICLE Vl

                               VACATIONS WITH PAY

(a)    Any employee who works during at least thirteen (13) weeks in either
       each calendar year or each anniversary year, as defined in the Local
       Agreements, shall be granted a vacation off work without loss of pay,
       according to the following schedule:

(b)    All employees who have completed one or more anniversary years of
       service but less than five (5) years of service will be entitled to two
       (2) weeks of vacation, provided they meet all other requirements of this
       Article.

       Employees who have completed five (5) or more anniversary years of
       service but less than fifteen (15) years of service will be entitled to
       three (3) weeks of vacation, provided they meet all other requirements
       of this Article.

       Employees who have completed fifteen (15) or more anniversary years of
       service, but less than twenty-five (25) years of service, will be
       entitled to four (4) weeks of vacation, provided they meet all other
       requirements of this Article.

       Employees who have completed twenty-five (25) or more anniversary years
       of service will be entitled to five (5) weeks of vacation, provided they
       meet all other requirements of this Article.

       Article Vl (b) above to the contrary notwithstanding, no employee (who
       meets all the other requirements of this Article Vl) shall be entitled
       to any fewer weeks of vacation than he was entitled to take in 1984.


(c)    Vacation pay will be based on a forty (40) hour week at the rate of the
       permanently assigned classification on which an employee is working at
       the time he takes his vacation. If an employee has held a single higher
       rated classification for more than six (6) months during the year
       preceding his vacation, he will receive vacation pay computed at the
       higher rate. Vacation pay shall include appropriate shift differential
       for those on fixed shift. Employees working on rotating shifts shall be
       paid an average of the rates for the rotating shifts involved.

(d)    Vacations will not be cumulative, but so far as practicable, be granted
       at times most desired by the employees, but the final right to allotment
       of vacation period is exclusively reserved to the Company in order to
       insure the orderly operation of the plant. In exercising its right to
       allot vacation periods, the Company will not require any employee who is
       on layoff to take his vacation during periods of plant shutdown or
       curtailment of operation. Where requested vacation periods conflict,
       preference shall be given to the older employee in point of service.

(e)    It is further agreed that if any employees have previously selected
       their vacation period so that it occurs during an unforeseen shutdown
       such vacation period shall not be changed.

       Vacation shall be taken by the employee within the calendar year in
       which it is granted as determined by the Local Agreements.



                                       22

(f)    No employee will be required and/or requested to work during his seven
       day vacation period. The only exception will be when a classification
       has two or fewer employees, no qualified personnel are available except
       the employee on vacation, and an emergency situation exists. In that
       event an employee on vacation may be requested to work.

(g)    The rules governing the submission of appropriate vacation application
       blanks shall be defined by the Local Agreement.

(h)    Upon two weeks written notice by an employee to the Personnel Clerk, the
       Company will give him his vacation pay on the employee's last shift
       prior to the beginning of his vacation.

                                   ARTICLE VII

                                    HOLIDAYS

(a)    The Company will grant eleven (11) paid holidays; these holidays shall be
       listed in each Local Agreement.

(b)    If any such holiday falls on Sunday, the following Monday shall be the
       recognized holiday. The holiday hours shall be those hours within the 24
       hour period commencing with the beginning of the first shift on the
       morning of the holiday and ending at the beginning of the first shift
       the following day.

(c)    Employees who are scheduled to work on a holiday shall be paid two and
       one-half (2.5) times the regular straight time hourly rate.

(d)    Hours worked on a holiday in excess of eight (8) in a workday, in excess
       of forty (40) in a workweek, on off-days, and on callouts shall be paid
       for at the applicable overtime rate.


(e)    If no work is required of an employee on the above holidays, he will
       receive eight (8) hours pay at the regular straight time hourly rate,
       provided he meets the following qualifications.

       (1)    The employee shall have been employed by the Company for at least
              thirty (30) calendar days prior to the holiday.

       (2)    The employee shall have worked his last scheduled working day
              prior to and his next scheduled working day after such holiday
              unless excused therefrom by the Plant Manager on account of
              sickness, accident, death in the family, or other excused
              absence. In no event shall a holiday be paid for unless an
              employee has also worked during the thirty (30) day period
              immediately preceding or immediately following the holiday except
              that the thirty (30) day limitation shall not apply if the
              employee was temporarily absent from work because of sickness,
              accident or layoff. In any event, the employee must work at least
              one day in the calendar year in which the holiday is granted.

(f)    If an employee is scheduled to work on a holiday and fails to work, he
       shall not receive holiday pay, unless excused therefrom by the Plant
       Manager.



                                       23
<PAGE>   24

(g)    If an employee works on a holiday, the holiday shall be counted as a day
       worked for computing weekly overtime. Paid holiday is to count as a day
       worked for overtime purposes, provided holiday falls on one of
       employee's scheduled workdays and he would have worked that day except
       for holiday observance.

(h)    An employee not scheduled to work the holiday and who subsequently
       performs work on a holiday will be considered as being on callout and
       will be paid eight (8) hours at the regular straight time hourly rate in
       addition to two (2) times the regular straight time hourly rate for all
       time worked with a minimum of four (4) hours at double time.

(i)    Work schedules for each workweek which include a holiday will be posted
       prior to the end of the first shift on Thursday of the previous week. If
       an employee is scheduled to work on a holiday, but then is instructed by
       the Company not to work, he shall receive for that holiday eight (8)
       hours pay at two and one-half (2.5) times the regular straight time
       hourly rate.

(j)    The phrase "regular straight time hourly rate" as used solely in Article
       Vll, Holidays, shall mean the higher of either the employee's regular
       straight time hourly rate or to the highest straight time hourly rate
       for a job on which the employee works at least eight (8) consecutive
       hours in the workweek in which the holiday falls provided (1) that the
       eight hours had been previously scheduled or (2) the hours are worked
       the day before or the day after the holiday whether previously scheduled
       or not.





                                  ARTICLE VIII


                                     WAGES


(a) Considered a part of the Local Agreements are the current Job
Classifications and Rate Lists.

(b)    (1)    Scheduled shift workers on the first shift shall receive the
              regular straight time hourly rate.

       (2)    Scheduled shift workers on the second shift shall receive the
              regular straight time hourly rate plus 52(cent) per hour.

       (3)    Scheduled shift workers on the third shift shall receive the
              regular straight time hourly rate plus 75(cent)per hour.



                                       24
<PAGE>   25

       (4)    These premium rates do not apply to day workers even though they
              may work over into premium paid shift.

       (5)    If a day worker is scheduled to take the place of a regular
              scheduled shift worker, then the premium rate for the shift shall
              apply.

       (6)    The premium pay does not alter the provisions covered in this
              contract under the head of "Working Conditions".

(c)    Shift differentials shall be included as part of the regular rate in the
       calculation of overtime compensation.

(d)    The Company may at its discretion increase wages in any class or to an
       individual in any class without necessitating a change in the rate of
       any individual or class.

(e)    Any job not mentioned in this Agreement or any job with substantial
       changes in duties, equipment or requirements, or any new job created in
       the plant, shall be open for negotiations by the Company and the Union
       as to wages upon written notice from either party to the other party. If
       no agreement can be reached during the above negotiations, the matter
       shall be subject to the grievance procedure.





                                   ARTICLE IX

                             HANDLING OF COMPLAINTS

(a)    All employees shall at all times make an effort to perform their duties
       in such a manner as to promote safe and efficient operation of their
       department and the plant as a whole.

       (1)    Should a difference arise between an employee and the Company as
              to the meaning and application of this Agreement or should a
              difference arise as to the meaning and application of a
              recognized practice, the employee with or without his steward
              shall present his complaint to his foreman within ten (10)
              working days after the date of the alleged wrong or within ten
              (10) working days after the date the employee received his
              payroll check, whichever is later. Failure by the employee and/or
              the Union to 


                                       25
<PAGE>   26

              observe this time limit shall cause the grievance to be considered
              settled in favor of the Company.

       (2)    The foreman shall orally reply to the employee within five (5)
              working days after the date the employee presented his complaint
              in Section (1). Failure by the Company to observe this time limit
              shall cause the grievance to be considered settled in favor of
              the employee.

       (3)    If the employee is not satisfied with the foreman's reply, the
              employee may request his steward to present the grievance in
              writing to the Union Grievance Committee. If the Union Grievance
              Committee believes that the complaint is justified, it may submit
              the complaint in writing to the Plant Manager within five (5)
              working days of the date of the foreman's reply in Section (2).
              The Plant Manager shall schedule a meeting with the Union
              Grievance Committee and any member or members of the staff that
              the Plant Manager desires to have present. This meeting shall
              take place within fifteen (15) working days of the date the Union
              Grievance Committee submits the grievance to the Plant Manager.
              Failure to observe any time limit shall cause the grievance to be
              considered settled in favor of the employee if the Company has
              failed to observe the time limit or in favor of the Company if
              the employee and/or the Union has failed to observe the time
              limit.

       (4)    The parties shall use their best efforts to settle the complaint.
              If the parties agree upon the disposition of the grievance, they
              shall reduce their understanding to writing and the grievance
              shall be settled. If the parties are unable to agree, the Union
              Grievance Committee may at the employee's request and within
              thirty (30) days of the date of the meeting between the Plant
              Manager and the Union Grievance Committee submit the grievance in
              writing to the Director of Industrial Relations or his
              representative with copies to the International Vice President or
              District Council Representative and the Plant Manager. The
              Director of Industrial Relations shall contact the International
              Vice President or District Council Representative within seven
              (7) days after receipt of the grievance to schedule a meeting.
              The parties shall use their best efforts to schedule the meeting
              within thirty (30) days. Failure to observe any time limit shall
              cause the grievance to be considered settled in favor of the
              employee if the Company has failed to observe the time limit or
              in favor of the Company if the employee and/or the Union has
              failed to observe the time limit.

       (5)    After full consideration, and such conference as may be mutually
              agreed upon with an International or District Council
              Representative of the Union, the grievance shall be considered
              settled when the employee's and the Company's representative
              shall have reached an agreement.

       (6)    If the parties are unable to settle the grievance, either party
              can notify the other party in writing that it intends to submit
              the grievance to arbitration. This notice must be given within
              ten (10) days of the last meeting in Section (5) OR AFTER TEN
              (10) DAYS WRITTEN RESPONSE FROM THE COMPANY. The consent of the
              other party is not required to arbitrate a grievance.

              The foregoing to the contrary notwithstanding, either party may
              exercise the following option:



                                       26
<PAGE>   27

              For the purpose of expediting and facilitating the resolution of
              a grievance which has been processed through step (5) of the
              grievance procedure and which would otherwise be submitted to
              arbitration, either the Company or the Union may elect to submit
              said grievance to a panel which will consist of a Vice President
              of the International Union or his representative and the Vice
              President of Operations of the Company or his representative,
              provided that no member of the panel can be a party to any
              discussion of the grievance during an earlier step of the
              grievance procedure. Each party can submit a maximum of five (5)
              grievances to the panel during any calendar year. Only a
              grievance about the interpretation of contract language in the
              Basic or Local Agreement can be submitted to the panel. A party
              electing to submit said grievance to the panel must notify the
              panel and the other party within ten (10) days after a decision
              has been made at step (5). The authority of said panel shall be
              no greater than the authority of the arbitrator as set forth in
              (d) of the grievance procedure. The panel shall meet at the Plant
              where the grievance arose.

              A maximum of two members of the Union Grievance Committee can
              attend a panel meeting. The decision of the said panel shall be
              final and binding upon the Company and the Union. In the event
              the Union representative on the panel and the Company
              representative on the panel are unable to agree, either the Union
              or the Company may elect to submit such grievance to arbitration
              as provided in step (6) of the grievance procedure. The party
              electing to arbitrate the grievance must give notice to the other
              party within ten (10) days after the Union representative on the
              panel and the Company representative on the panel have jointly
              informed the parties that the panel is unable to make a decision.
              Failure to observe any time limit shall cause the grievance to be
              considered settled in favor of the employee if the Company has
              failed to observe the time limit or in favor of the Company if
              the employee and/or the Union has failed to observe the time
              limit.

(b)    If either party does not notify the other within ninety (90) days of the
       notice of its intent in (a) (6) above, that it now wishes to mutually
       select an arbitrator and schedule a hearing date, then the parties shall
       consider the grievance to have been withdrawn by the moving party.


       When the moving party notifies the other of its wish to mutually select
       an arbitrator, the parties shall select an arbitrator within ten (10)
       days. Failing to reach an agreement upon the selection of an arbitrator,
       the moving party may request the appointment of an arbitrator by either
       the Federal Mediation and Conciliation Service or the American
       Arbitration Association.

       Grievances heard by the arbitrator must be presented in chronological
       order based on the date the grievances were written except in discharge
       cases which may be presented out of chronological order or in cases
       where the parties have mutually agreed in writing to waive the
       chronological order requirement.

                                       27
<PAGE>   28

(c)    All time limits set forth in (a) and (b) shall be strictly observed;
       time limits can be extended by a written agreement between the parties.

       Whenever the term "working days" occurs in the grievance procedure, it
       shall be defined by the parties to mean plant work days, Monday through
       Friday.

       Whenever the term "days" is used in this section, it shall be defined by
       the parties to mean calendar days.

(d)    The arbitrator shall consider only the grievance appealed to him and
       shall have jurisdiction and authority only to interpret, apply, or
       determine compliance with the provisions of this Agreement, and only the
       extent necessary to determine the grievance. The arbitrator shall not
       have jurisdiction or authority to add to, modify, detract from, or alter
       in any way the provisions of this Agreement.

(e)    The arbitrator's decision shall, at the request of either party, be in
       writing and shall be final and binding on both parties. The fees and
       expenses of the arbitration proceeding, except fees for witnesses
       brought in by either party and legal counsel's fees, shall be borne
       equally by the Company and the Union. Bargaining unit employees
       including Committeemen who participate in arbitration proceedings shall
       not be compensated by the Company.

(f)    Grievances involving the provisions of the collective bargaining
       agreement and occurring so as to be processed to arbitration at the same
       time will be at the request of either party arbitrated before the same
       arbitrator. However, it is agreed that not more than four (4) cases will
       be heard at one series of hearings.

(g)    Local Union officers and stewards off-duty and representatives of the
       International Union and District Council shall, upon notice to the
       Company, be permitted on Company's premises to investigate grievances.

(h)    Meetings will be conveniently scheduled so as to complete all business
       within the normal working day for day employees. Any employee who is
       scheduled to work during the hours the meeting is held and who attends
       the meeting will be compensated by multiplying the regular straight time
       hourly rate by the hours he attends the meeting. In addition, if the
       employee attends the meeting beyond his normal quitting time, he will be
       compensated for each additional hour he attends the meeting by
       multiplying the regular straight time hourly rate by one (1) and said
       additional hour or hours shall not count toward daily or weekly
       overtime.

       Any member of the Committee who is not scheduled to work during the
       hours the meeting is held, who is not scheduled to work the third shift
       immediately preceding the meeting, or who is not scheduled to work the
       second shift immediately following the meeting, and who attends the
       meeting, will be compensated by multiplying his regular straight time
       hourly rate by all hours he attends the meeting. Any hours paid under
       this paragraph shall not count toward the calculation of any penalty or
       premium pay section of this Agreement including but not limited to daily
       or weekly overtime. Any employee who is receiving S.U.B. benefits,
       sickness and accident benefits, or Workmen's Compensation benefits for
       the day of the meeting or who is absent due to disciplinary layoff shall
       not receive any compensation under this paragraph.



                                       28
<PAGE>   29

       When a meeting is scheduled at which a representative of the
       International Union and a representative of the Company from Cleveland
       will attend, any member of the committee who is scheduled work the third
       shift immediately preceding the meeting will be excused from working the
       third shift and will be compensated by multiplying eight (8) hours at
       the regular straight time hourly rate plus shift differential if the
       employee has attended the meeting.

       Any member of the committee who is scheduled to work the second shift
       immediately following the meeting will be excused from working the
       second shift if the employee has attended the meeting for six (6) hours.
       In the event the employee is excused from working the second shift, he
       will be compensated by multiplying eight (8) hours at the regular
       straight time hourly rate plus shift differential.

(i)    The Company will reimburse no more than two (2) members of the Union's
       bargaining Committee from each Local Union for scheduled time lost due
       to attendance at and travel to and from Basic Agreement Negotiations.
       One day travel time shall be allowed the day before such meeting, and
       one day travel time shall be allowed after such meeting. The rate of pay
       will be the regular straight time hourly rate including Sunday premium,
       if applicable.

(j)    Disciplinary letters issued to employees will remain in the Company's
       employee file for twelve (12) months. At the end of the twelve (12)
       month period, the disciplinary letters will not be used against the
       employee in the future for purposes of progressive discipline.
       DISCIPLINE OF ONE WEEK OR MORE WILL NOT BE USED AFTER FIVE YEARS.

       This provision shall not apply if the discipline letter refers to a
       disciplinary suspension of one week or more.

(k)    Where there is a discussion between an hourly employee and a supervisor
       that is intended as a disciplinary measure, the Company requests that a
       grievance committeeman, job steward or other designated employee be
       present.

       A "disciplinary measure" shall be limited to the issuing of a reprimand
       or the imposition of a penalty to an employee about which a notation,
       letter or unsatisfactory performance report is subsequently made part of
       the employee's personnel file.

       It shall be the responsibility of the Union to appoint and have
       available on each shift a committeeman, job steward or other employee
       designated for purposes of this section who shall be identified to the
       Corporation in writing.

       It is not the intent of this Section to expand the total number of
       committeemen as provided for in each Local Supplemental Agreement.


(l)    When a grievance involving pay is settled in favor of the Union, the
       employee entitled to such pay shall be paid by the second pay following
       the settlement.

                                   ARTICLE X

                              STRIKES AND LOCKOUTS

(a)    Having provided an orderly procedure for settling all disputes, the
       Company agrees not to lock-out its employees and the Union agrees that
       there will be no strikes or work stoppages during the term of this
       Agreement.

(b)    The Company agrees not to hold the Union liable when such activities are
       not authorized by the Union, provided that the Union within forty eight
       (48) hours orders its members to cease and desist from such activities.

(c)    It shall not be a violation of this Agreement or cause for disciplinary
       action including discharge if an employee refuses to cross a picket line
       that has been established in full compliance with existing laws. Picket
       lines established as a result of jurisdictional disputes, picket lines
       established for the purpose of organizing in-plant non-bargaining unit
       personnel, and/or informational picket lines are excluded from this
       protection.

       Notwithstanding the above, employees will not honor any picket line
       unless authorized by the International Union. The International Union
       will not be held liable for any subsequent damage to the Corporation
       resulting from refusal of employees to cross an authorized picket line.

                                   ARTICLE XI

                                     SAFETY

(a)    The Company will, according to its established practice, continue to
       install such safety devices for the protection of the lives and health of
       its employees as are required by the Workmen's Compensation laws of the
       State in which the plants covered by this Agreement are located. The
       Company will maintain the washhouse with heat, light and plenty of hot
       water, and keep the toilets, fixtures and floors in a sanitary condition,
       and will supply good drinking water wherever necessary about the plant.
       Sufficient equipment and tools shall be maintained in a safe and
       efficient working order, and the regulations and safety codes adopted by
       the Department of Labor of the applicable state, in the interest of
       protecting the safety and health of industrial employees as they affect
       this industry, be strictly observed by both parties.


(b)    The Company agrees to furnish first aid and medical service to its
       workers in any cases originating out of their work in the Company plant,
       in compliance with the Workmen's Compensation laws of the applicable
       state. Medical services shall be performed by a doctor to be agreed upon
       by the Company and the plant safety committee, but at the request of the
       injured, and the approval of the Plant Manager and Director of Industrial
       Relations, other medical aid may be called in at the expense of the
       Company for consultation or treatment of any cases. It is agreed that a
       complete medical examination may be required before an 


                                       30
<PAGE>   31

       applicant is employed. Also, that complete medical examination may be
       made annually or at any time at the discretion of the Company. Copies of
       such reports and examinations will be kept on file by the Company and
       shall at all times be available for inspection to such employees. Copies
       thereof shall be furnished to such employee's designated physician upon
       request.

(c)    A Joint Safety and Health Committee shall be established consisting of
       four members, two appointed by the Company and two appointed by the
       Local Union. In the event that a member is absent from a meeting of the
       Committee, his alternate may attend and when in attendance shall
       exercise the duties of the member. The Safety Director or his designee
       will be the fifth member and act as Chairman of the Committee.

       The Joint Committee shall meet as often as necessary, but not less than
       once each month at a regularly scheduled time and place for the purpose
       of jointly considering, inspecting, investigating and reviewing health
       and safety conditions and practices and investigating accidents and for
       the purpose of jointly and effectively making constructive
       recommendations with respect thereto, including but not limited to the
       implementation of corrective measures to eliminate unhealthy and unsafe
       conditions and practices and to improve existing health and safety
       conditions and practices. All matters considered and handled by the
       Committee shall be reduced to writing, and joint minutes of all meetings
       of the Committee shall be made and maintained. One union representative
       to the Committee will accompany a Federal or State investigator on a
       walk-around inspection or investigation, and will attend any pre-or
       post-inspection conferences.

       All time spent in connection with the work of the Committee by a Union
       Representative including all time spent in pre-or post-inspection
       conferences and walk-around time spent in relation to Federal and State
       inspections and investigations as provided for above, shall be
       compensated at the employee's regular straight time hourly rate. Any
       time spent during the hours the employee is scheduled to work shall
       count toward the calculation of any penalty or premium pay section of
       this Agreement including, but not limited to daily or weekly overtime.
       Any time spent outside of the hours the employee is scheduled to work
       shall not count toward the calculation of any penalty or premium pay
       section of this Agreement. No time spent outside of the hours the
       employee is scheduled to work shall be compensated at a rate greater
       than one (1) times the employee's regular straight-time hourly rate.

       Any employee who believes his job presents a hazard to his safety or
       health may request an immediate review of his job by the Joint Safety
       and Health Committee.

       No employee shall be disciplined or discharged for refusing to work on a
       job if his refusal is based on a bona fide claim that said job is not
       safe or might unduly endanger his health or safety.


(d) (1) An employee shall be paid a premium when he is required to:

       A.     work within a kiln during the first ten (10) hours that the kiln
              has been shutdown after it has been operating at a normal level;



                                       31
<PAGE>   32

       B.     work within a cooler during the first two (2) hours that the
              cooler has been shut down after it has been operating at a normal
              level;

       C.     work within a kiln precipitator during the first four (4) hours
              following the shut down of the kiln providing the precipitator
              was handling the kiln gases at the time of kiln shutdown;

       D.     work within a section of a kiln precipitator or a kiln baghouse
              while the kiln is in operation and the other sections of the
              baghouse or the precipitator are in use.

              The premium shall be calculated by multiplying the regular
              straight time hourly rate by one-half (0.5) for each and every
              hour worked up to the 10, 2, and 4 hours mentioned in A, B, C,
              AND D above. Said premium shall be paid in addition to whatever
              compensation the employee is otherwise entitled to receive under
              any other section of this Agreement.

       (2)    Each Plant Safety Committee will meet to determine those areas of
              the Plant where an employee is subject to excessive radiant heat
              for extended periods of time. The Committee will consider all
              conditions which affect the level of heat encountered including
              ambient air temperature. Upon making said determination, the
              Committee will decide what the Company shall provide as
              reasonable protective apparel against excessive radiant heat.

       (3)    In the event that an employee is required to work on top of
              roofs, silos, scale a quarry face or work in a silo, UNDER
              CONDITIONS WHERE A PREMIUM HAS CUSTOMARILY BEEN PAID, the hours
              worked shall be compensated for by multiplying the regular
              straight time hourly rate by one-half (0.5) for each and every
              hour worked UNDER THESE CONDITIONS and this work premium shall be
              paid in addition to whatever compensation the employee is
              otherwise entitled to receive under any other section of this
              Agreement.

(e)    Should the Company require an employee to wear foot protection, the
       Company will furnish such protection without cost to the employee. The
       liability of the Company with regard to safety shoes will be limited to
       not more than two (2) pair in any one year. A new pair of shoes will
       only be provided an employee when the worn out pair is turned in for
       replacement. THE COMPANY AGREES TO ALLOW AN $80 REIMBURSEMENT FOR SAFETY
       SHOES BEGINNING MAY 1, 1998. THIS ALLOWANCE IS TO BE INCREASED BY $2.50
       ON THE ANNIVERSARY DATE EACH YEAR OF THE AGREEMENT.

(f)    If a mandatory eye protection program is adopted: (1) the Company will
       pay for the cost of the eye examination if safety glasses with
       corrective lenses are required; (2) the Company will pay for safety
       glasses whether or not the glasses require corrective lenses. Safety
       glasses with or without corrective lenses will not be replaced more than
       once a year unless broken or otherwise damaged on the job.


(g)    The Company shall furnish all tools and equipment for its employees
       except to repairmen and other skilled trades, in which case these
       employees shall furnish their own hand tools. 


                                       32
<PAGE>   33

       "Hand tools" as used herein shall not include socket sets, wrenches more
       than twelve (12) inches long, and all other specialized tools incident to
       the work of the mechanical, maintenance and skilled trades. Any hand tool
       that the employee uses in the performance of his job duties will be
       replaced by the Company if they are broken, worn out, lost or stolen.
       Unusable tools will be presented to the Company prior to replacement.
       Lost or stolen tools must be immediately reported to the Company for
       replacement approval. Employees temporarily transferred to maintenance
       classifications shall be supplied with necessary tools.

(h)    The Furnishing of Gloves: The Company will continue its existing local
       practices regarding the furnishing of gloves.

       Employees who are not presently receiving gloves under existing local
       practices shall receive one pair of gloves at the beginning of each
       contract year, and each such employee shall receive a maximum of one
       additional pair per contract year from the Company upon return of his
       worn out gloves.

       In the event such an employee wears out and returns the two pairs of
       gloves provided to him, the Company shall sell him an additional pair of
       gloves for each worn out pair of Company provided gloves he returns.
       Said gloves shall be sold to the employee at the price paid by the
       Company.

(i)    If the Company requires an employee to take a physical examination, the
       Company agrees to pay for the physical examination and also agrees to
       pay the employee at his straight time hourly rate for all time spent in
       the doctor's office taking the physical examination; provided, however,
       employees receiving S & A and/or Workmen's Compensation benefits are not
       entitled to any compensation under this section. (Doctor releases for
       returning to work are not considered physical examinations and will not
       be paid under this section).



                                  ARTICLE XII

                                MILITARY SERVICE

(a)    The Company and the Union shall comply with the Universal Military
       Training and Service Act of 1950, as amended.

(b)    Active employees with one year seniority and who are in the Reserve of
       any branch of the military service, including the National Guard, who
       are required to attend a summer encampment as part of their Reserve
       obligation shall receive from the Company the difference between the
       amount of pay received for such encampment and his regular straight time
       hourly rate of pay for up to a maximum of two (2) weeks per calendar
       year.

                                  ARTICLE XIII

                     SUPPLEMENTAL UNEMPLOYMENT BENEFIT PLAN

The Company agrees to pay out of its funds (and not out of the Trust Fund
established under Article III of the Plan) benefits in amounts equal to those
provided by Section 2 of Article VIII of the Plan upon termination of
employment on or after May 1, 1965, after an employee (as defined in Section 6,
Article II of the Plan) is sixty-five years old, provided such employee is not
eligible for a pension under the current Pension Plan for Hourly Employees of
the Company.

The foregoing to the contrary notwithstanding, the above payment shall not be
paid directly by the Company until termination benefits paid from the Trust and
Contingent Funds exhaust those funds.

                                  ARTICLE XIV

                                 SUBCONTRACTING

(a)    The Company will not contract for production or maintenance work
       customarily performed by its own employees unless it is more economical,
       expeditious, and/or efficient to do otherwise.

(b)    The Company may enter into contract arrangements for obtaining raw
       materials, semi-finished or finished products.

(c)    Notwithstanding the above, the Company will not contract or subcontract
       work covered by Paragraphs (a.) or (b.) above if it will directly result
       in the 1) laying off of (or failure to recall qualified) bargaining unit
       employees, or 2) the reduction of hours of bargaining unit employees
       below 40 hours a week; or 3)
       reduction of employees to a lower rated classification.

       It is understood that layoffs attributable to such things as inventory
       or production adjustments, changes in methods, processes or
       technologies, and/or break downs or failure of equipment power failure
       or any conditions beyond the control of the Company, are specifically
       exempted from this commitment.

(d)    Further, (a), (b) and (c) above does not apply to new construction or to
       construction involved in major modification work.

(e)    The Company agrees to notify the Local Union in writing with a copy to
       the International or District Representative who services the Local
       Union, sent by registered mail, at least fourteen (14) days in advance if
       reasonably possible, and to meet with the Union, upon request by the
       Union, for explanation of the reasons causing the Company to decide to
       contract any production and maintenance work. The parties agree that
       while notification is an important part of the working relationship
       between the parties and should be adhered to in order to reduce the
       number of disputes concerning sub-contracting the parties also recognize
       and agree that this Section of the Contract does not require any penalty
       when the Company fails to give proper written notice of its intention to
       sub-contract.

                                   ARTICLE XV

                                 MISCELLANEOUS

(a)    The Company will enter into a Union label agreement for the Company's
       packaged products.

(b)    All basic, supplemental, pension, S.U.B. and insurance agreements will
       be printed at the Company's expense and will bear the Union label. The
       Company will provide each local with a supply of the booklets. The
       Company will print all Agreement booklets in large and legible type.

(c)    If the Union alleges that a Leadman or Temporary Foreman is exceeding or
       abusing his authority or that his actions violate the Contract, the
       Union may grieve their allegations directly to the Plant Manager. The
       Company will notify the employees involved whenever a Leadman or
       Temporary Foreman is being assigned.

                                   ARTICLE XVI

                                     401(K)

       THE COMPANY WILL ESTABLISH A 401(k) PLAN TO BEGIN AUGUST 1, 1998 WITH
       EMPLOYEE CONTRIBUTIONS UP TO 4% TO BE MATCHED 50% BY THE COMPANY.
       BEGINNING MAY 1, 2000, EMPLOYEE CONTRIBUTIONS UP TO 5% TO BE MATCHED 50%
       BY THE COMPANY, AND MAY 1, 2002 EMPLOYEE CONTRIBUTIONS UP TO 6% TO BE
       MATCHED 50% BY THE COMPANY.



                                  ARTICLE XVII

                                TERM OF AGREEMENT

(a)    This Agreement shall be binding upon the parties hereto, their
       successors, administrators, executors and assigns. In the event of the
       sale or lease by the Company of any of the plants covered by this
       Agreement, or in the event the Company is taken over by sale, lease,
       assignment, receivership or bankruptcy proceeding, such operations shall
       continue to be subject to the terms and conditions of this Agreement for
       the life thereof.

       The Company will notify the Union immediately prior to any Company press
       release concerning the intended sale or completed sale of a Plant.

       The Company shall give notice of the existence of this Agreement to any
       purchaser, lessee or assignee of said plant. Such notice shall be in
       writing with a copy to the Union not later than the effective date of
       the sale.



                                       35
<PAGE>   36



(b)    After ratification by the members of the Local Unions this Agreement
       shall become effective and remain in full force and effect and be binding
       upon the parties hereto from the date ratification is certified by the
       International Union to and including April 30, 2004 and it shall continue
       in full force and effect thereafter from year to year until either party
       on or before March 1st of any year, beginning March 1, 2004 gives written
       notice to the other party of its desire or intention either to alter or
       modify or to terminate the same. If such notice is given, the parties
       hereto shall begin negotiations not later than March 31st in such year
       and this Agreement shall continue in full force and effect until
       completion and signing a new Agreement, provided, however, that after
       such negotiations have continued without reaching an agreement until May
       1st in any year, then either party may terminate this Agreement, at any
       time thereafter upon notice.

(c)    The written notice set forth in (b) above by either party shall contain
       any changes or amendments desired, and only such changes or amendments
       as are contained in the two written notices shall be discussed by the
       conferees.

(d)    The proposals and counter-proposals made by each party shall not be
       used, or referred to, in any way during or in connection with the
       arbitration of any grievance arising under the provisions of the
       Agreement.

Ratification of this Basic Agreement and the Local Agreements was certified by
J.C. Todd, International Union Representative, on ______________________.

                                (B.A. Article 1)

Mr. Thomas Hawkins
Chairman, Local D23
UNITED CEMENT, LIME GYPSUM AND
ALLIED WORKERS' INTERNATIONAL UNION
Clinchfield Plant

Dear Mr. Hawkins:

It is understood by both the Union and the Company that the Director of
Industrial Relations will contact the payroll department of each plant to make
arrangements that will allow for S.U.B. payments to be made by the end of the
second week an employee is laid off. This arrangement will be made within a six
(6) week period following the ratification of the 1975 contracts by the Local
Union.

It is further understood that any S.U.B. payments made in advance of meeting the
requirement of the existing S.U.B. agreement between the parties will remain
subject to Section 7, Recovery of Overpayments, of the S.U.B. Agreement.

Very truly yours,



Peter H. Geis
Director of Labor
 Relations & E.E.O.

                               CLINCHFIELD PLANT

LOCAL AGREEMENT NO. 76-3

It is agreed and understood by the Medusa Cement Company and the United Cement,
Lime and Gypsum Workers' Local No. 23 that in the awarding of all future
permanent vacancies, qualifications (skill and ability) gained through
temporary assignment to a job will not be considered in determining the
successful bidder for the job bid. It is further agreed and understood that the
above interpretation will apply only to the initial job posted for bid, and
will not apply to subsequent jobs posted for bid which result from the vacancy
created by the initial job award.

The conditions of this agreement become effective on September 10, 1976.

Additional Language - Local Agreement 76-3


Experience gained through temporary assignment to a job will not be considered
in determining the successful bidder in job brackets 1 through 10, regardless
of whether or not it is an initial bid or subsequent bid.

If the Union determines that evidence indicates that the Company is
pre-training certain employees so that employees are being discriminatorily
selected for a particular job opening, it may present this allegation in the
form of a grievance which will commence at the third step of the grievance
procedure.

If an employee wishes to meet with the Administrative Assistant to exercise his
wish to be trained on another classification, he may do so, and his request
will be given careful consideration.

                           RE: Filling Overtime Needs


It is hereby agreed and understood that when overtime work is needed for
non-shift workers, company management will ask available qualified persons in
the job class involved to do the work. And if no qualified person accepts the
overtime, then the lowest man in overtime qualified to do the work will be
required to fill the overtime need.

In the case of shift workers, they will still be required to stay on overtime
if necessary until they are relieved.

                 MEMORANDUM OF CLINCHFIELD LOCAL AGREEMENT 80-1




It is understood and agreed by the Medusa Cement Company and the United Cement,
Lime and Gypsum Workers' Local No. 23 that historically and customarily the
delivery of parts and supplies to the Clinchfield, Georgia plant has been
performed by both bargaining unit and non-bargaining unit employees as well as
numerous vendors, truck drivers, salespersons, suppliers, etc. This agreement
is to recognize this fact and to reduce the incidents of parts and supplies
being delivered by non-bargaining unit Medusa employees.

It is understood and agreed that the following conditions will become effective
on the date signed by both parties:


           Whenever it is necessary for a Medusa employee to travel beyond a
           fifteen (15) mile radius of the Clinchfield, Georgia plant to pick
           up parts and supplies, a bargaining unit employee will be utilized
           to operate the vehicle except when:

          A.   It is necessary for a non-bargaining unit employee to select or
               identify the needed parts and supplies.

          B.   A non-bargaining unit employee is already in the vicinity of the
               location where the parts and supplies are to be acquired.

INDEPENDENT AUDITORS' REPORT


To the Shareholders and Board of Directors of Southdown, Inc.


We have audited the accompanying consolidated balance sheet of Southdown, Inc.
and subsidiary companies as of December 31, 1998 and 1997, and the related
statements of consolidated earnings, shareholders' equity, cash flows and
comprehensive income for each of the three years in the period ended December
31, 1998. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated 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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits 
provide a reasonable basis for our opinion. 

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Southdown, Inc. and subsidiary
companies as of December 31, 1998 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1998 in conformity with generally accepted accounting principles.

SOUTHDOWN, INC. AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


  
[1]  THE COMPANY AND BASIS OF PRESENTATION:

Southdown, Inc. is one of the largest producers of cement in the U.S. The
Company operates twelve portland cement manufacturing plants located in Alabama,
California, Colorado, Florida, Georgia, Kentucky, Michigan, Ohio, Pennsylvania,
Tennessee and Texas, plus an extensive network of cement distribution terminals.
The Company also mines, processes, and sells construction aggregates and
specialty mineral products in the eastern half of the U.S. and in California. In
addition, the Company markets ready-mixed concrete products in two of its
largest cement markets, California and Florida. For more information describing
the Company's operations and the relative importance of the Company's business
segments, see Note 4 of Notes to Consolidated Financial Statements.

The consolidated balance sheet of Southdown as of December 31, 1998 and 1997 and
the related statements of consolidated earnings, shareholders' equity, cash
flows and comprehensive income for each of the three years in the period ended
December 31, 1998 are presented on the basis of generally accepted accounting
principles. On June 30, 1998, the Company concluded a merger transaction with
Medusa Corporation. Medusa became a 100% owned subsidiary of the Company at that
time. The Company treated the transaction as a "pooling of interests" rather
than a purchase of one company by another. A pooling of interests accounts for a
business combination as the uniting of the ownership interests of companies by
an exchange of stock. (See also Note 3 of Notes to Consolidated Financial
Statements.)

Southdown was organized in Louisiana in 1930 and maintains its principal
executive offices at 1200 Smith Street, Suite 2400, Houston, Texas 77002-4486,
telephone (713) 650-6200. The Company reorganized its corporate structure at the
end of 1998 by merging most of its recently acquired Medusa entities into
Southdown and contributing the Company's California cement, concrete products
and aggregates operations to certain existing and newly created wholly-owned
subsidiaries of the Company. The terms "Southdown" and the "Company" as used in
this report, include subsidiaries of Southdown and also predecessor
corporations.

[2]  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

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. These estimates and assumptions also affect the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

CONSOLIDATION -- The consolidated financial statements of the Company include
the accounts of its divisions, its wholly-owned subsidiaries and its
majority-owned joint venture after elimination of significant intercompany
transactions and balances. All prior period consolidated financial statements
presented provide the combined results of operations, financial position and
cash flows of the Company and Medusa. Certain data for prior years have been
reclassified for purposes of comparison.

<PAGE>   7

CASH AND STATEMENT OF CONSOLIDATED CASH FLOWS SUPPLEMENTAL DISCLOSURES -- The
Company considers short-term investments, which have an original maturity of
three months or less, to be cash equivalents for purposes of the Statement of
Consolidated Cash Flows. Cash payments for income taxes totaled $71.7 million in
1998, $57.1 million in 1997 and $35.7 million in 1996. Interest paid, net of
amounts capitalized, was $16.4 million, $14.3 million and $20.8 million in 1998,
1997 and 1996. Interest capitalized was $1.7 million in 1998, $2.9 million in
1997 and $2 million in 1996.

There were no non-cash financing activities in 1998. Non-cash financing
activities in 1997 included the conversion of 1.7 million shares of preferred
stock with a carrying value of $86.3 million into 2.6 million shares of common
stock. Non-cash financing activities in 1996 included the conversion of 2.9
million shares of preferred stock with a carrying value of $65.6 million and the
conversion of $26.7 million in Medusa's convertible subordinated notes into a
total of 4 million shares of common stock.

In 1998, non-cash investing activities included the assumption of $1.4 million
in liabilities in connection with Medusa's acquisition of an aggregate operation
and a highway safety systems company. Non-cash investing activities in 1997
included the assumption of liabilities in Medusa's various acquisitions as
discussed in Note 4 of Notes to Consolidated Financial Statements.

INVESTMENTS -- In addition to cash equivalents, the Company has investments in
debt securities that mature in more than three months but no more than one year.
The Company expects to hold all such investments to maturity and, therefore,
carries these investments at amortized cost. The Company does not recognize
gains or losses on these investments, which the Company deems to be temporary,
because the Company has both the intent and the ability to hold these
investments until they mature. As of December 31, 1998 and 1997, the Company's
investments consist primarily of commercial paper maturing within one year. The
fair value of these investments approximates their amortized cost. (See also
Note 11 of Notes to Consolidated Financial Statements.)

INVENTORIES -- The Company values inventories at the lower of cost or market.
Cost includes material, labor and manufacturing overhead. The Company values
cement inventories on the last-in, first-out method. The valuation of the
remaining inventories, primarily parts and supplies, is determined on the
first-in, first-out or average cost method. (See also Note 7 of Notes to
Consolidated Financial Statements.)

PROPERTY, PLANT AND EQUIPMENT -- The Company capitalizes all direct and certain
indirect expenditures incurred in conjunction with the acquisition or
construction of major facilities. Depreciation and amortization of these
capitalized costs commence when the completed facility is placed in service.
Depreciation and amortization of property, plant and equipment are computed
primarily on a straight-line basis over estimated useful lives of the related
assets, ranging from three to 50 years. On average, the Company depreciates
buildings and improvements based on a 50 year life; machinery and equipment over
lives ranging from ten to 35 years; office furniture, fixtures and equipment
over lives ranging from five to ten years and mobile equipment over lives
ranging from four to 25 years. The Company computes depletion of mineral rights
on the units-of-production method.

The Company reviews long-lived assets for impairment whenever events or changes
in circumstances indicate that the carrying amount of those assets may not be
recoverable. If the sum of the expected future undiscounted cash flows is less
than the carrying amount of the asset, a loss is recognized for the difference
between the fair value and the carrying value of the asset. Gain or loss is
generally reflected in earnings upon the retirement or sale of property, plant
and equipment. (See also Note 8 of Notes to Consolidated Financial Statements.)


<PAGE>   8

ENVIRONMENTAL EXPENDITURES -- The Company bases its estimates of environmental
liabilities on the nature or extent of contamination, methods of remediation
required, existing technology, presently enacted laws and regulations and prior
Company experience in remediation of contaminated sites. The Company capitalizes
environmental expenditures that extend the life, increase the capacity, or
improve the safety or efficiency of property owned by the Company, mitigate or
prevent environmental contamination that has yet to occur, or that are incurred
in anticipation of a sale of property. Expenditures that relate to an existing
condition caused by past operations, and which do not contribute to current or
future revenue generation, are expensed. The Company's policy is to accrue
environmental and clean-up related costs of a non-capital nature when it is both
probable that a liability has been incurred and the amount can be reasonably
estimated, whether or not a claim has been asserted or this coincides with the
completion of a remediation investigation/feasibility study or the Company's
commitment to a formal plan of action. The Company revises such estimates as
additional information becomes known. (See also Note 17 of Notes to Consolidated
Financial Statements.)

GOODWILL -- The Company amortizes the excess of cost over the fair value of net
assets of businesses acquired, on a straight-line basis, over periods ranging
from 15 to 40 years. Such amortization amounted to $3.7 million in 1998, $3.5
million in 1997 and $3 million in 1996. Accumulated amortization of goodwill was
$38.6 million and $34.9 million as of December 31, 1998 and 1997. The Company
utilizes estimates of undiscounted future cash flows of the acquired operations
to evaluate any possible impairment of the related goodwill.

REVENUE RECOGNITION -- The Company generally recognizes revenue on the sale of
products or services when the products are shipped or the services delivered,
all significant contractual obligations have been satisfied and the collection
of the resulting receivable is reasonably assured.

OTHER INCOME, NET -- Other income, net consists primarily of gains and losses on
miscellaneous asset sales and insurance recoveries.

INTEREST INCOME -- Interest income, earned primarily on investments in
short-term securities, totaled $5.9 million in 1998 compared with $3.3 million
in 1997 and $3.4 million in 1996. The Company also recognizes interest income on
impaired loans using a combination of the cost recovery and the cash basis
methods. The Company recognized no material amounts of interest income on
impaired notes receivable during 1998 and 1997, but recognized approximately
$1.1 million of such interest income during 1996.

STOCK-BASED COMPENSATION -- As permitted by Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation", the Company
continues to account for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees." Accordingly, no compensation expense has been
recognized for the Company's employee stock option plans. The disclosure-only
provisions of SFAS No. 123 have been included in Note 19 of Notes to
Consolidated Financial Statements.

INCOME TAXES -- In computing its federal and state income tax liabilities, the
Company uses accelerated depreciation and deducts currently certain expenditures
that are capitalized for financial reporting purposes. Deferred income taxes are
provided on these and other temporary differences between the tax bases of
assets and liabilities and their bases for financial statement purposes.
Investment tax credit carryforwards are accounted for under the flow-through
method and, accordingly, reduce federal income taxes in the years in which their
utilization is assured. (See also Note 13 of Notes to Consolidated Financial
Statements.)

<PAGE>   9
EARNINGS PER SHARE -- The Company computed basic earnings per share using
average number of common shares outstanding in each of the three years ended
1998. Earnings used to compute basic per share earnings in 1997 and 1996 were
net of preferred stock dividends of approximately $2.5 million in 1997 and $7.7
million in 1996, respectively. Diluted earnings for 1998 assume the dilutive
impact of options. Diluted earnings for 1997 and 1996 assume the dilutive impact
of options and warrants and the conversion of all shares of pr eferred stock to
common stock. Diluted earnings for 1996 also assume the conversion of the then
outstanding Medusa convertible subordinated notes into shares of common stock.
(See also Note 18 of Notes to Consolidated Financial Statements.)

NEW ACCOUNTING STANDARDS -- Effective January 1, 1998, the Company adopted three
new Statements of Financial Accounting Standards: Statement No. 130, "Reporting
Comprehensive Income", Statement No. 131, "Disclosures About Segments of an
Enterprise and Related Information" and Statement No. 132, "Employers'
Disclosures About Pensions and Other Postretirement Benefits". Adoption of these
three new standards had no material effect on the Company's consolidated results
of operations, financial position, or cash flows.

SFAS No. 130 establishes standards for reporting and displaying comprehensive
income and its components. The Company elected to report the components of
comprehensive income in a separate Statement of Consolidated Comprehensive
Income.

SFAS No. 131 establishes standards for the way that public companies report
information about operating segments in interim and annual financial statements.
An operating segment is somewhat the same as a "line of business". The technical
definition is "a component of a business, for which separate financial
information is available that management regularly evaluates in deciding how to
allocate resources and assess performance". The Company's reporting of
information about its operating segments already conformed with SFAS No. 131
prior to adopting this new standard. Medusa, which adopted SFAS No. 131 in 1997,
had two segments, cement and aggregates, which the Company considers to be
reportable. After the merger, the Company's California aggregates operations,
which were previously included in the Concrete Products segment, are now
included in the Aggregates segment along with the aggregates operations of
Medusa.

In an effort to standardize disclosure requirements for pensions and other
postretirement benefits to the extent practicable, the Financial Accounting
Standard Board issued SFAS No. 132. SFAS No. 132 revises employers' disclosures
about pension and other postretirement benefits, but does not change the
measurement or recognition of those plans. These revised disclosures may be
found in Note 16 of Notes to Consolidated Financial Statements. 

In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities". A derivative is a financial instrument that
takes or "derives" its value from the value of some other financial instrument.
SFAS No. 133 requires that a company recognize all derivatives as either assets
or liabilities on its balance sheet and measure those instruments at fair value.
Fair value is the amount for which an object would currently change hands
between a willing buyer and an independent willing seller. SFAS No. 133 is
effective for years beginning after June 15, 1999 and management is currently
evaluating what, if any, impact this new accounting standard may have on the
Company's consolidated financial statements. The Company held no derivative
financial instruments during the three year period ending December 31, 1998.

[3]    Medusa Merger:

On June 30, 1998, Medusa became a wholly-owned subsidiary of the Company. The
Medusa merger converted each outstanding Medusa common share into the right to
receive .88 shares of Company common stock. The Company issued approximately
14.7 million shares of its common stock for all of the outstanding common stock
of Medusa. The Medusa merger also converted Medusa's outstanding employee stock
options the same way, so these Medusa options became options to purchase
approximately 522,000 shares of Company common stock. The exchange of Medusa
shares and options for Company shares and options was tax-free. The Company
accounted for the merger as a pooling of interests as allowed by Accounting
Principles Board Opinion No. 16, "Business Combinations."

The Company recorded second quarter charges to operating expenses totaling $82.9
million ($73.9 million after taxes, or $1.90 per common share, diluted) for
direct and other merger related transaction costs. These transaction costs
include severance related costs for approximately 150 former employees at the
Medusa corporate office, professional fees, financial printing, and anticipated
closure of duplicate corporate office facilities and incompatible business
practices, processes and activities. A significant portion of the severance
costs accrued was related to certain performance based restricted stock grants
that had been awarded to Medusa executive officers. Severance cost related to
these restricted stock awards was estimated based on the market price of the
Company's common stock as of the June 30, 1998 merger date.

Because the market price of the Company's common stock, like that of many other
companies' common stock, declined between the merger date and the August 1998
date the restrictions on the stock awards actually lapsed, the cost of Medusa
executive severance was less than originally estimated. Accordingly, the Company
recorded a third quarter 1998 credit of $6.7 million to estimated severance
expense. On the other hand, the Company revised upward its initial estimate of
other merger transaction and closure costs. The net effect was a $4 million
third quarter 1998 reduction in estimated transaction costs.

In the fourth quarter of 1998, the Company recognized a $3.7 million further
reduction in estimated transaction costs as a result of curtailment gains on
Medusa pension and other postretirement benefit plans directly related to the
Medusa corporate office that is to be closed. (See also Note 16 of Notes to
Consolidated Financial Statements.)

At December 31, 1998, current liabilities related to transaction costs were $7.4
million. The Company expects the closure of the Medusa corporate office to be
complete and the last of the Medusa corporate office personnel to terminate by
the end of the first quarter of 1999. Details of the merger related costs are as
follows:

</TABLE>

For interim reporting purposes, the Company recorded adjustments to conform the
accounting practices of Medusa to those of the Company. The adjustments related
primarily to Medusa's deferral of maintenance costs and use of standard cost
accounting for inventory. However, because the deferral of maintenance costs and
the use of the standard cost method of valuing inventory impacts only interim
reporting periods, there are no differences in previously reported Medusa assets
and net earnings for the full years ended December 31, 1997 and 1996.

[4]  BUSINESS SEGMENT INFORMATION:

While all operations of the Company are related to some degree and share certain
internal services, the Company has identified three business segments, each of
which is managed separately along product lines. The Cement segment includes the
operations of eleven quarrying sites, twelve manufacturing facilities and a
network of 44 cement storage and distribution terminals for the production,
importation and distribution of portland and masonry cement. The Concrete
Products segment includes primarily the production and sale of ready-mixed
concrete in two of the Company's largest cement markets, southern California and
Florida, and to a lesser extent, the sale of concrete block in Florida. The
Aggregates segment mines, processes and sells construction aggregates in the
eastern half of the U.S. and in southern California and specialty mineral
products in the eastern half of the U.S. It also operates a subsidiary that
installs highway safety systems such as guardrails, traffic signals, highway
signage and lighting. After the Medusa merger, the Company's California
aggregates operations, which the Company previously included in the Company's
Concrete Products segment, were transferred to the Aggregates segment. The
Company has restated the presentation of prior year segment information below to
reflect this change. Operating results and certain other financial data for the
Company's principal business segments for and at the end of each year presented
are as follows:

Corporate overhead is generally not allocated to the operating segments. Other
unallocated corporate assets consist primarily of cash, goodwill, prepaid
pension costs and office furniture, fixtures and equipment. Substantially all of
the Company's operations are conducted in the U.S. Intersegment sales occur
primarily between the Company's Florida cement manufacturing plant and the
related Florida concrete products operations and the Company's southern
California cement manufacturing plant and the related California concrete
products operations. The Company accounts for intersegment sales at prices which
approximate market prices, but eliminates these sales for purposes of preparing
consolidated financial statements. Depreciation, depletion and amortization
shown above includes $.8 million of amortization of debt issuance costs in 1998
compared with $1 million of such amortization in 1997 and $2.7 million of
amortization of debt issuance costs in 1996. Capital expenditures shown above
exclude capital acquisitions of $6 million in 1998, $30.2 million in 1997 and
$6.2 million in 1996.

AGGREGATES ACQUISITIONS -- During 1997, Medusa completed two cash acquisitions
at a cost of $30.2 million, net of cash and liabilities assumed of $19.4
million. In January 1997, Medusa acquired Lime Crest Corporation, a leading
producer of home and garden products, industrial limestone and construction
aggregates based in Sparta, New Jersey. In October 1997, Medusa acquired Lee
Lime Corporation, a producer of limestone, quicklime, hydrated lime, packaged
cement mixes and a leading producer of home and garden products based in Lee,
Massachusetts.

In August 1997, Medusa also purchased all of the capital stock of White Stone
Company of Southwest Virginia. This company is a producer of industrial
limestone and aggregates in Castlewood, Virginia with a limestone pelletizing
plant in Paradise, Pennsylvania. In consideration of the purchase price of $34.7
million as well as an election by Medusa to step up the basis of the assets
acquired for income tax purposes, Medusa assumed liabilities of $3.2 million and
issued notes to the selling shareholders for $31.5 million. The notes to the
selling shareholders were paid in full prior to Medusa's merger with the
Company.

Medusa accounted for all three 1997 acquisitions by the purchase method. Medusa
allocated the purchase prices to assets acquired and liabilities assumed based
on fair market value at the dates of acquisition. Medusa included the results of
operations for all three acquisitions in the financial statements from their
respective dates of purchase. On an unaudited proforma basis, assuming Medusa
had completed the three acquisitions as of the beginning of 1996, net sales for
1997 and 1996 would have increased $20.3 million and $36.1 million,
respectively, whereas net income and net income per common share would not have
been significantly different from reported amounts for either period.

SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK -- A majority of the Company's
receivables are from users of portland cement, such as ready-mixed concrete
producers and manufacturers of concrete products such as blocks, roof tile, pipe
and prefabricated building components. Sales are also made to building materials
dealers, other cement manufacturers, construction contractors and, particularly
from the Texas plant, oil well cementing

companies. During the three years ended December 31, 1998, approximately 43%,
58% and 58% of the Company's Texas plant's cement sales volume consisted of oil
well cement sales. The Company is a major producer of ready-mixed concrete in
California and is also a major producer and supplier of such products in
Florida. The Company's California plant made approximately 17%, 19% and 18% of
its cement sales in the three years ended December 31, 1998 to the Company's
ready-mixed concrete operations in California. Approximately 36%, 38% and 38% of
the cement sold by the Company's Florida plant in three years ended December 31,
1998 was sold to the Company's Florida concrete products operations. Aggregates
sales, both construction and specialty aggregates, are to a wide spectrum of
customers including national home improvement warehouse chains, large industrial
concerns and individual local small businesses. Construction aggregates are sold
to the construction industry primarily for use in the manufacture of concrete
and asphalt as well as a variety of construction applications such as road base,
drainage blankets, erosion control and other applications. Specialty aggregates
sells over 200 products with many different uses including, among others, lawn
care, gardening, landscaping, grounds maintenance, water conditioning,
agriculture and in the manufacture of joint compounds, caulk, paints, plastics
and paper. There were no sales to any single third-party customer in any of the
Company's business lines, which totaled in excess of 10% of consolidated
revenues for 1998, 1997 or 1996.

An analysis of the activity in the allowance for doubtful accounts follows:

In the opinion of management, the Company is adequately reserved for credit
risks related to its potentially uncollectible receivables. However, the Company
continues to assess its allowance for doubtful accounts and may increase or
decrease its periodic provision as additional information regarding the
collectibility of these and other accounts becomes available.

Land held for sale includes various non-income producing real estate parcels
offered for sale. Unamortized debt issuance costs are costs and expenses
associated with the issuance of certain of the Company's senior debt and senior
subordinated notes. Debt issuance costs are being amortized over the respective
terms of the debt. In conjunction with the purchase of Moore McCormack
Resources, Inc. in 1988, the Company acquired two contracts to supply flyash
through 1999 and 2004, respectively. The supply contracts were recorded at their
net present values at the date of acquisition and are being amortized over the
respective lives of the contracts.

[11] DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS: 

The Company considers investments with maturities between three and twelve
months as short-term. Short-term investments consist of debt securities such as
commercial paper, time deposits and certificates of deposit. The Company
classified all of its short-term investments as of December 31, 1998 as
held-to-maturity in accordance with Statement of Financial Accounting Standards
No. 115, "Accounting for Certain Investments in Debt and Equity Securities."
Because of the short duration of these investments, changes in market interest
rates would not have a significant impact on their fair value. Accordingly, the
fair market value of these investments approximates their amortized cost of
$14.8 million and $4 million as of December 31, 1998 and 1997. 

The carrying amounts of the Company's other assets and liabilities which are
considered to be financial instruments approximate their value, except for
long-term debt. The Company determined the estimated fair value amounts for the
Company's long-term debt as of December 31, 1998 and 1997 by using appropriate
valuation methodologies and information currently available to management.
Considerable judgment is required in developing these estimates and,
accordingly, the Company can not guarantee that the estimated values shown
indicate the amounts that would be realized if the Company were to replace its
long-term debt in a free market exchange. The fair value of the Company's
long-term debt was estimated based on the quoted market prices for similar
issues or on the current rates available to the Company for debt with similar
terms and remaining maturities.

REVOLVING CREDIT FACILITY -- The Company's revolving credit facility is with
Wells Fargo Bank, N.A., in its individual capacity and as agent; Societe
Generale, Southwest Agency; The Bank of Nova Scotia; Credit Suisse First Boston;
Credit Agricole Indosuez; PNC Bank, N.A.; Banque Paribas and BankBoston, N.A. In
May 1998, the Company amended this $200 million revolving credit facility to
permit (1) the Medusa merger, (2) assumption of the existing indebtedness of
Medusa of up to $100 million, and (3) the guarantee of a $15 million lease
obligation associated with the Medusa merger. The Company also obtained from its
bank group a release of the bank group's liens on the collater-

<PAGE>   17

al security, including the security interest in five of the Company's cement
plants and the Company's interest in the Kosmos joint venture. In December 1998,
the Company again amended its credit agreement to permit (1) the contribution or
other transfer of certain California assets to certain existing and newly
created wholly-owned subsidiaries of the Company and (2) the merger of Medusa
entities with and into the Company.

In early June 1998, Medusa reduced the borrowing capacity under its unsecured,
five-year revolving credit facility from $180 million to the $40 million then
outstanding. The Company paid off the outstanding balance on the Medusa credit
facility on June 30, 1998. There were no amounts outstanding on Medusa's
unsecured $25 million bank lines of credit on June 30, 1998. Medusa's bank group
cancelled both credit facilities as of June 30, 1998.

The Company's revolving credit facility matures in June 2002. The credit
facility permits the issuance of up to $95 million in standby letters of credit
in lieu of borrowings. Borrowings under the facility bear interest at margins
either at or above a prime rate or above the London Interbank Offered Rate as
selected by the Company from time to time. As of December 31, 1998, the Company
had $67 million in letters of credit outstanding under this facility, but no
borrowings, leaving $133 million available. The revolving credit facility limits
the Company's additional indebtedness, but allows the Company to borrow up to
$175 million, as well as certain other amounts, from other lenders.

Under the revolving credit facility, the Company must maintain the following
financial ratios: (1) leverage ratio (funded debt compared with consolidated
earnings before interest, tax and depreciation), (2) minimum current ratio
(current assets compared with net current liabilities), and (3) free cash flow
ratio (free cash flow compared with the sum of interest, dividends, current tax
provision and current portion of funded debt). In addition, the Company must
maintain a minimum tangible net worth (shareholders' equity minus intangible
assets such as goodwill).

Under the terms of the Company's 10% Senior Subordinated Notes Indenture, the
Company may borrow up to $255 million under bank credit facilities, plus $50
million of additional debt and certain other additional amounts. Under the
indenture, the Company may borrow more than those amounts if the Company's
consolidated fixed charge coverage ratio is more than 2.25 to 1. The fixed
charge coverage ratio is the ratio of after tax earnings, excluding interest
charges, to the amount of interest due on all indebtedness. As of December 31,
1998, the Company's consolidated fixed charge coverage ratio was significantly
higher than 2.25 to 1. That indenture also limits "Purchase Money Obligations"
and/or "Capitalized Lease Obligations" to not more than $25 million at any one
time and restricts, among other things, certain sales of assets, certain mergers
and consolidations, dividends and distributions and redemptions and repurchases
of equity securities. 

The Company is in compliance with the revolving credit facility and indenture
ratios and covenants. Generally, the revolving credit facility is more
restrictive than the indenture and would limit the Company's additional
borrowings before covenants in the indenture would impede the Company's ability
to incur additional debt.

INDUSTRIAL DEVELOPMENT AND POLLUTION CONTROL BONDS -- The industrial development
and pollution control bonds were issued by various state or local financing
authorities and are due on various dates through the year 2017. The obligations
bear interest, which is nontaxable to the payees, at varying rates that
approximate 50% of the prevailing prime rate. The obligations are secured by
irrevocable letters of credit issued under the Company's revolving credit
facility. During the first quarter of 1998, the Company negotiated an extension
of $17.8 million of the pollution control bonds until 2013. The Company refunded
bonds totaling $7.5 million during 1997, extending their maturity until 2017.

<PAGE>   18

10% SENIOR SUBORDINATED NOTES -- On March 19, 1996, the Company issued an
aggregate of $125 million principal amount of 10% Senior Subordinated Notes in a
private placement. The net proceeds of the Notes and other funds were used to
retire $125 million in principal amount of the Company's 14% Senior Subordinated
Notes, which the Company had offered to repurchase. The total cost to the
Company was $136.9 million plus accrued interest. The Company recorded a $11.5
million net of tax extraordinary charge in 1996 to reflect the prepayment
premium and other costs incurred in the repurchase.

The Company issued the Notes pursuant to an indenture dated as of March 19, 1996
between the Company and State Street Bank and Trust Company, as Trustee. During
1996, all of the Notes were exchanged in a registered exchange offer for $125
million aggregate principal amount of the Company's 10% Senior Subordinated
Notes pursuant to a registration rights agreement entered into at the time of
the private placement. The 10% Notes were also issued under the indenture, and
the terms of the 10% Notes are substantially identical to those of the Notes.
The 10% Notes pay interest semiannually, mature on March 1, 2006 and are
noncallable until March 1, 2001, after which the 10% Notes are callable at the
option of the Company, in whole or in part, at any time at 105% of the principal
amount, declining ratably in annual increments to par on or after March 1, 2004.
The 10% Notes are subordinate in right of payment to all existing and future
senior debt, as defined, of the Company, rank on a parity with all existing and
future senior subordinated debt, as defined, of the Company, and rank senior to
all other existing and future subordinated debt of the Company. The indenture
includes affirmative and negative covenants, which in certain instances
restrict, among other things, additional indebtedness, sales of assets, mergers
and consolidations, dividends and distributions and redemptions and repurchases
of equity securities.

MEDUSA 6% CONVERTIBLE SUBORDINATED NOTES -- Also in 1996, Medusa redeemed its 6%
convertible subordinated notes. Medusa note holders converted $26.7 million in
Medusa notes into 805,161 Medusa common shares. The other note holders were
redeemed for $30.8 million. This redemption, including the write -off of
unamortized debt issuance costs, was $1.8 million net of income tax benefit of
$.8 million and also was reflected as an extraordinary item in 1996.

ANNUAL TOTAL MATURITIES OF LONG-TERM DEBT -- The expected maturity dates, the
approximate total principal payments due in future years and the average
interest rate on long-term debt as of December 31, 1998 are as follows:

The provision for deferred income taxes represents the change in the Company's
deferred income tax liability during each year, including the effect of any
enacted tax rate changes. The Company recognizes a deferred income tax liability
or asset for the net effect of (1) temporary differences between the tax bases
of assets and liabilities and their reported amounts in the financial statements
after applying enacted statutory tax rates and laws in effect for the year in
which the differences are expected to reverse and, in certain instances, (2) the
deferred tax effects of tax net operating loss and tax credit carryforwards.

Significant components of the Company's net deferred tax liability as of
December 31, 1998 and 1997 were as follows:

The consolidated federal income tax returns of the Company for 1993 through 1995
and various state income tax returns are currently under examination. In the
opinion of management, the Company has made adequate provision at December 31,
1998 for income taxes that might be due as a result of these audits and any
resulting assessments will have no material effect on the Company's consolidated
earnings.


[14] MINORITY INTEREST IN CONSOLIDATED JOINT VENTURE:

Kosmos Cement Company is a partnership, which owns a cement plant located in
Louisville, Kentucky and a cement plant located near Pittsburgh, Pennsylvania
along with related terminals and facilities. The partnership is 25% owned by
Lone Star Industries, Inc. and operated and 75% owned by the Company. The
Company's Consolidated Balance Sheet includes 100% of the assets and liabilities
of Kosmos. Lone Star's 25% interest in Kosmos and the earnings therefrom have
been reflected as "Minority interest in consolidated joint venture" and
"Minority interest, net of income taxes" on the Company's Consolidated Balance
Sheet and Statement of Consolidated Earnings, respectively.

</TABLE>

DEFERRED PAYMENT OBLIGATION -- In connection with the July 1990 purchase of a
hazardous waste processing facility from an affiliate of Browning-Ferris
Industries, Inc., the Company assumed a conditional payment obligation payable
to the former shareholders of the Browning-Ferris subsidiary. The expected
timing of payments related to the estimated liabilities on discontinued
operations and the deferred payment obligation is uncertain.

<PAGE>   21

DISCONTINUED OPERATIONS -- The Company has accrued loss provisions for certain
environmental issues under the indemnification provisions of sales agreements
associated with the environmental services operations discontinued in 1994 and
for which the Company remains contingently liable. In addition, as part of the
acquisition of Moore McCormack in 1988, the Company assumed certain fixed and
contingent liabilities pursuant to certain guarantees and undertakings related
to operations that had been previously discontinued by Moore McCormack.

[16] PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS: 

PENSION -- The Company has a defined benefit pension plan covering substantially
all employees. The benefits are based on years of service and the employee's
compensation and are integrated with Social Security. The Company's policy is to
fund its pension plan in accordance with sound actuarial principles. 

To determine the funded status of the Company's pension plan, the Company's
actuaries compare the market value of the plan's assets at the end of the year
with actuarial estimates of the projected benefit obligation. Differences in
estimates used and actual experience along with changes in assumptions from
year-to-year are included in net deferred gains or losses. The Company amortizes
the unrecognized net gains or losses whenever such amount exceeds 10% of the
greater of the projected benefit obligation or the market value of plan assets.
The unrecognized net obligation or net asset, unrecognized net gain or loss and
prior service costs were amortized over periods of 5 to 13 years for 1998, over
periods of 5 to 12 years for 1997 and over periods of 6 to 15 years for 1996,
which approximated the estimated average remaining service periods of employees
expected to receive benefits under the plan.

The Company recognized pension income of approximately $6 million, $3.1 million
and $1.7 million in 1998, 1997 and 1996, respectively, under such
Company-sponsored plans. The 1998 amount excludes the $3.7 million curtailment
gain on the Medusa pension and postretirement benefits. In addition to the
Company-sponsored plan, certain union employees of the Company's Colorado cement
operations, the Great Lakes shipping company, the Butler, Kentucky aggregates
operation and the highway safety systems company are covered under a
multi-employer defined benefit plan administered by its union. Amounts
contributed to the multi-employer plans and included in pension expense were
$1.5 million in 1998, $0.8 million in 1997 and $1.2 million in 1996.

The Company acquired Medusa on June 30, 1998, including its pension and
postretirement benefit plans. As a result of the closing of the Medusa corporate
office, the expected years of future service under the Medusa pension and
postretirement plans have been reduced for a significant number of employees.
Under the provisions of Statement of Financial Accounting Standard No. 88,
"Accounting for Settlements and Curtailments of Defined Benefit Pensions Plans
and for Terminated Benefits", and Statement of Financia l Accounting Standard
No. 106, "Employers' Accounting for Postretirement Benefits Other Than Pension",
the curtailment of the Medusa plans resulted in the recognition of $3.7 million
in gains in 1998. Because the curtailment is directly related to the merger
transaction, the Company recognized the gain as a reduction in estimated
transaction costs. (See also Note 3 of Notes to Consolidated Financial
Statements.) The remaining Medusa plans will be amended to establish parity with
the benefits provided by the Company.

DIRECTORS PENSION PLAN -- The Company also has an unfunded defined benefit
pension plan covering the members of its Board of Directors who have five years
of service and are not participants in any of the Company's qualified pension
plans. Eligible directors are entitled to a monthly benefit equal to two-thirds
of their average monthly fee. The benefit is payable over a number of months
equal to such director's service on the Board. During 1998, 1997 and 1996, the
Company included in expense $535,000, $151,000 and $154,000, respectively, to
provide for benefits accrued under the plan. 


<PAGE>   22

RETIREMENT SAVINGS PLAN -- The Company maintains a retirement savings plan in
which substantially all employees are eligible to participate. The savings plan
is designed to qualify under Sections 401(a) and 401(k) of the Internal Revenue
Code. Under the savings plan, a participating employee may elect to defer
taxation on a portion of his or her eligible earnings up to a maximum amount
defined by the Code, by directing the Company to contribute such earnings to the
savings plan on the employee's behalf. A participating employee may also make
after-tax contributions to the savings plan. The Company contributes an amount
to the savings plan equal to 50% of an employee's contributions, subject to
certain limitations. The Company's matching contributions are invested solely in
its common stock acquired in open market purchases. All employee contributions
and Company matching contributions are fully vested when made. Amounts held by
the savings plan for the account of a participating employee are distributable
as a lump-sum upon termination of employment for any reason. Subject to certain
conditions and restrictions, a participating employee may receive a distribution
or a loan of a portion of his account balance while employed by the Company. The
Company contributed $3 million in 1998, $2.7 million in 1997 and $2.5 million in
1996, in matching contributions that were charged to compensation expense and
invested in the Company's common stock. 

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN -- Effective October 1, 1997, the Company
adopted a non-qualified supplemental retirement plan for a group of senior line
and staff management personnel. Under this plan, participants will receive an
additional monthly retirement benefit. The additional benefit is equal to the
difference between the amount calculated under the Company's qualified defined
pension benefit plan discussed above and the amount that would be calculated
assuming there were no limitations imposed by the Internal Revenue Code on
compensation, including incentive compensation earned pursuant to the Company's
Annual Incentive Plan. 

The plan is unfunded. The annual amount charged to pension expense and accrued
as a pension liability under the plan for financial reporting purposes is the
sum of (1) the present value of the actuarially determined projected benefit
obligation, using an assumed weighted average discount rate of 6.875% and an
assumed rate of increase in future compensation levels of 4.5%, and (2) the
amortization of the unrecognized prior service cost over a period of 8 years,
which approximates the estimated average remaining service period of those
certain senior employees expected to receive benefits under the plan. The
Company recognized pension expense under this plan of $612,000 and $146,000
during 1998 and 1997. As of December 31, 1998, the unrecognized prior service
cost and the projected benefit obligation for the plan were $1.8 million and $3
million, respectively. As of December 31, 1997, the unrecognized prior service
cost and the projected benefit obligation for the plan were $2.1 million and
$2.5 million, respectively.

SUPPLEMENTAL PENSION LIABILITIES -- A small number of former employees and
retirees of the Company are eligible for payments under non-qualified
supplemental pension agreements. Under such arrangements, the Company accrued
the present value of probable future cash outlays during the expected service
life of the employee and charged that amount against earnings for financial
reporting purposes. 

HEALTH CARE AND LIFE INSURANCE BENEFITS -- The Company offers health care
benefits to active employees and their dependents. Certain retirees under the
age of sixty-five and their dependents are also offered health care benefits,
which consist primarily of medical and life insurance benefits. However, the
Company reduces benefit payments for covered retirees sixty-five years of age or
older by benefits paid by Medicare. 

The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation for general health care and prescription drugs
was approximately 8%, 8.5% and 9% as of December 31, 1998, 1997 and

<PAGE>   23

1996, respectively. For all three years, the Company assumed rates would
decrease each successive year until it reaches rates ranging from 5% to 6% in
2004 and thereafter. The health care cost trend rate assumption has a
significant effect on the amount of the obligation and periodic cost reported.
For example, a one-percentage-point change in assumed health care cost trend
rates would have the following effects:

Effect on postretirement benefit obligation                          8.5%               7.5%
</TABLE>

Most of the Company's health care benefits are self-insured and administered on
cost plus fee arrangements with a major insurance company or provided through
health maintenance organizations. Claims, premiums and administrative costs paid
for active employees and their dependents were $16.6 million, $14.5 million and
$13 million in 1998, 1997 and 1996, respectively. For retirees and their
dependents these costs were $3.7 million in 1998, $3.8 million in 1997 and $4.2
million in 1996.

The Company provides life insurance benefits to its active and retired
employees. Generally, life insurance benefits for retired employees are reduced
over a number of years from the date of retirement to a minimum level. Costs
paid for life insurance benefits for employees were approximately $1.1 million
in 1998, $910,000 in 1997 and $742,000 in 1996. The costs of providing such
benefits for retired employees were de minimis in each of the three years in the
period ended December 31, 1998.

The pension plan's assets exceeded the accumulated benefit obligation as of both
December 31, 1998 and 1997. None of the Company's accumulated postretirement
benefit obligation has been funded. The following table provides a
reconciliation of benefit obligations, plan assets, funded status of the plans
and amounts recognized in the Company's Consolidated Balance Sheet at December

</TABLE>

ENVIRONMENTAL MATTERS -- The Company or its predecessors have conducted
industrial operations at some of the Company's facilities for almost 100 years.
Many of the raw materials, products and by-products associated with the
operation of any industrial facility, including those for the production of
cement, concrete products, or aggregates contain chemical elements or compounds
that are designated as hazardous substances. The Company's operations involving
such materials are regulated by federal, state and local laws and regulations
pertaining to the protection of human health and the environment. In the past,
in accordance with industry practice, the Company disposed of various materials,
both onsite and offsite, in a manner, which in some cases would not be permitted
under current environmental regulations. Certain of these materials, if
discarded today, might be categorized as hazardous substances or wastes.

Remediation under environmental clean-up rules can be costly. Federal
environmental laws, as well as analogous laws in certain states, create joint
and several liability for the cost of cleaning up or correcting releases into
the environment of designated hazardous substances. Among those who may be held
jointly and severally liable are those who generated the hazardous substances,
those who arranged for disposal of the hazardous substances, those who owned or
operated the disposal site or facility at the time of disposal, and subsequent
owners and operators. With regard to the discontinued environmental services
business, the Company has both given indemnification to and received
indemnification from others for properties previously owned, although a few
courts have held that indemnification for such environmental liabilities is
unenforceable. No estimate of the extent of contamination, remediation cost or
recoverability of cost from prior owners, if any, is currently available
regarding these discontinued operations except as noted below.

While several of the Company's facilities are the subject of various local,
state or federal environmental proceedings and inquiries, most of these
investigations are in their preliminary stages and final results may not be
determined for years. In certain instances, the Company has been named as one of
several potentially responsible parties charged with clean-up liability pursuant
to CERCLA. This disclosure is a statement of fact and is intended as general
cautionary advice that events of this kind are a reasonable possibility in the
cement industry, as well as in many other industries. The mere designation of an
entity as a potentially responsible party does not necessarily imply that it is
probable that an asset has been impaired or a liability has been incurred. In
fact, management considers all three of the Superfund sites in which the Company
has been identified as a potentially responsible party as of January 27, 1999 to
be of de minimus consequence to the Company. 

<PAGE>   26

Despite the fact that current law imposes joint and several liability on all
parties at any Superfund site, the Company's accrual for estimated liability in
these instances reflects only the Company's expected share based on the
Company's assessment of (1) its proportionate volumetric contribution to the
waste material, (2) whether responsibility is being disputed, (3) the terms of
any existing agreements, (4) the solvency of other parties and (5) experience
regarding similar matters. While some of these matters have been, or are
expected to be, settled for de minimis amounts, others are in their preliminary
stages and final results may not be determined for years. The Company accrues a
charge for an environmental reserve when it is probable that a liability has
been incurred and the amount of the liability is reasonably estimable, whether
or not claims have been asserted. All environmental accruals have been recorded
without giving effect to any possible future recoveries from insurance or other
third parties. It is often difficult to estimate the future impact of
environmental matters and accruals are adjusted as further information develops
or circumstances change.

Accrued liabilities specifically related to environmental matters were, in
total, $13.7 million, $13.6 million and $3.4 million at December 31, 1998, 1997
and 1996. Additional amounts related to closure, remediation and other
environmental related liabilities were included in the charge accrued in
conjunction with the 1994 loss on disposal of the discontinued environmental
services operations. Cash expenditures often lag by a number of years the period
in which an accrual is recorded. Based on the information developed to date, the
Company does not believe it will be required to spend significant sums on these
matters in excess of the amounts already provided for in the Company's financial
statements. Until all environmental studies, investigations, remediation work
and negotiations with or litigation against potential sources of recovery have
been completed, however, the ultimate cost that might be incurred by the Company
to resolve these environmental issues cannot be assured.

Additions to and expenditures charged against the Company's environmental
accruals related to continuing operations during the past three years were as
follows:

================================================================================
</TABLE>

Based solely upon the information developed to date, which is subject to change
as additional information becomes available, management of the Company believes
that known matters can be successfully resolved in cooperation with local, state
and federal regulating agencies. However, because the Company's results of
operations vary considerably with construction activity and other factors, it is
at least reasonably possible that future charges for environmental contingencies
could, depending on their timing and magnitude, have a material adverse impact
on the Company's results of operations in a particular period.

Amendments to the Clean Air Act in 1990 provided comprehensive federal
regulation of various sources of air pollution, and established a new federal
operating permit and fee program for virtually all manufacturing operations. The
Clean Air Act Amendments may result in increased capital and operational
expenses for the Company in the future, the amounts of which are not presently
determinable. As mandated by the Clean Air Act, beginning in late 1995, the
Company commenced submitting Federal operating permit applications and paying
annual fees for its cement manufacturing plants. In addition, the U.S.
Environmental Protection Agency is developing air toxics regulations for a 


<PAGE>   27

broad spectrum of industrial sectors, including portland cement manufacturing.
Management has no reason to believe, however, that these new standards would
place the Company at a disadvantage with respect to its competitors. 

In July 1997, the EPA promulgated revisions to two National Ambient Air Quality
Standards under the Clean Air Act -- particulate matter and photochemical
oxidants (ozone). Because of the nature of the Company's operations, the
proposed addition of a particulate matter standard that will regulate particles
2.5 microns or less in diameter, and the regulation of nitrogen oxides emissions
as the precursor pollutants to ozone, is of potential concern. Implementation of
these new standards will not immediately have an impact on industrial
operations. The first step is a several-year data collection and analysis
activity by the states to determine whether or not the state will be able to
meet the new standards. If a state is unable to demonstrate that it attains the
standards, it will then be required to modify its air quality implementation
plan to describe actions to meet the new standards. This initial phase will take
several years to complete. It is presently unknown whether states in which the
Company operates will be able to meet the new standards, how the states will
modify their implementation plans to demonstrate compliance or the ultimate
technology and cost impact on the Company's operations.

Another evolving issue of potential significance to the Company is global
warming and the international accord on carbon dioxide stabilization/reduction.
Carbon dioxide is a greenhouse gas many scientists and others believe
contributes to a warming of the Earth's atmosphere. In December 1997, the United
Nations held an international convention in Kyoto, Japan to take further
international action to ensure greenhouse gas stabilization or reduction after
the turn of the century. The conference agreed to a protocol to the United
Nations Framework Convention on Climate Change originally adopted in May 1992.
The protocol establishes quantified emission reduction commitments for certain
developed countries, including the U.S., and certain countries that are
undergoing the process of transition to a market economy. These reductions are
to be obtained by 2008-2012. The protocol was made available for signature by
member countries starting in the spring of 1998. The protocol will require U.S.
Senate ratification and enactment of implementing legislation before it becomes
effective in the United States.

The consequences of greenhouse gas reduction measures for cement producers are
potentially significant because carbon dioxide is generated from combustion of
fuels such as coal and coke in order to generate the high temperatures necessary
to manufacture cement clinker (which is then ground with gypsum to make cement).
In addition, carbon dioxide is generated in the calcining of limestone to make
cement clinker. Any imposition of raw material or production limitations or
fuel-use or carbon taxes could have a significant impact on the cement
manufacturing industry. It will not be possible to determine the impact on the
Company until governmental requirements are defined or the Company can determine
whether emission offsets or credits are obtainable, and whether alternative
cementitious products or alternative fuel can be substituted.

The Company's Wampum, Pennsylvania cement plant has received five Notices of
Violation from the U.S. EPA, alleging certain air emission violations. The U.S.
EPA has referred these notices to the U.S. Department of Justice for potential
civil enforcement. Three of the notices allege opacity and fugitive emissions
violations of Pennsylvania law and maintain that the provisions are enforceable
by federal authorities. The two remaining notices allege visible emissions
violations related to the provisions of the plant's state operating permit for
burning waste-derived liquid fuel. These notices also maintain that the state
permit provisions are enforceable by federal authorities. The parties have
negotiated a preliminary agreement in principle subject also to the negotiation
of a mutually agreeable consent decree. The Company anticipates that the consent
decree will include future

<PAGE>   28

compliance obligations and penalty payments. The Company does not expect the
penalty payments to materially exceed the amount the Company has already
reserved for this matter. Discussions are still on going, however, and
therefore, the Company is unable at this time to provide assurances as to the
ultimate liability that may be associated with these matters.

CLAIMS FOR INDEMNIFICATION -- The Mineral Management Service of the Department
of the Interior claimed that the Company's former oil and gas subsidiary, Pelto
Oil Company, owed royalties on two separate gas contract settlement payments
that Pelto received. When the Company sold Pelto in 1989, the Company agreed to
protect the purchaser from any future claims related to these two payments. In a
March 10, 1998 letter, the MMS advised that it was withdrawing its royalty claim
in the amount of $1.35 million on one of the settlement payments because of a
court ruling in July 1997, which prohibited further claims against the current
owner of Pelto and that owner's affiliates. The MMS, however, reserved its right
to possibly reassert the claim at a later date.

The Company also disagrees with MMS' claim that an unspecified amount of
royalties are owed on the second gas contract settlement payment of $5.9
million. If one or both of MMS claims against Pelto are ultimately successful,
the Company could have liability for royalties, plus late payment charges, in
amounts which are not currently determinable. Such expenditures would result in
a charge to discontinued operations.

KOSMOS CEMENT JOINT VENTURE SEVERANCE TAX AUDIT -- Kosmos Cement Company is a
partnership operated and 75% owned by the Company. In late 1997, the State of
Kentucky proposed a deficiency assessment against Kosmos for severance tax
payments related to limestone mined at its Battletown, Kentucky quarry. The
total assessment is approximately $3.7 million, including penalty and interest.
Kosmos is contesting the assessment. Kosmos met with the Kentucky Revenue
Cabinet in January 1998 to discuss the disputed assessments. Discussions are
ongoing and the Company is unable to evaluate whether an unfavorable outcome is
either probable or remote. 

In addition to limestone mined for the production of cement, Kosmos mines
limestone specifically for use by a local electric utility company. The Company
believes that, under the terms of a supply agreement, the utility company is
responsible for severance taxes on limestone provided to it. A major portion of
the Kentucky severance tax assessment relates to this specifically mined
limestone. For the amounts not paid by the local electric utility, the Company
would indirectly bear 75% of any settlement and legal costs through its
ownership interest in Kosmos.

DISCONTINUED ENVIRONMENTAL SERVICES SEGMENT -- The Company has both given and
received environmental and other indemnifications related to properties the
Company previously owned. A few courts have held that such promises to protect
other parties from loss for environmental liabilities are unenforceabl e. At
present, the Company is not able to estimate the extent of contamination,
remediation cost or recoverability of cost from prior owners, if any, regarding
these discontinued operations. 

In late 1994 and the first quarter of 1995, the Company learned of some soil and
groundwater contamination at its former Alabama hazardous waste processing
facility. Although the Company sold the facility in April 1995, the Company
agreed to keep some liability for soil and groundwater contamination at the
facility prior to that time. The Company's investigation has not yet determined
the extent of the contamination or what sort of cleanup, if any, will be
required. It is too early to determine the amount of the Company's exposure to
loss with any degree of certainty. 

The Company has agreed to remediate the soil and groundwater contamination at
the Alabama facility to the extent required by law, but filed a lawsuit against
the former owner of the facility. Claims against the prior owner and

<PAGE>   29

other potentially responsible parties could significantly reduce or eliminate
the Company's own loss exposure. Nevertheless, to cover the estimated cost of
investigating the amount of contamination present, conducting a ten year
monitored remediation program and pursuing the claim against the prior owner and
other potentially responsible parties, the Company recorded an additional $2.4
million expense ($1.6 million, after-tax) in the third quarter of 1998. The
charge is reflected as a "loss from discontinued operations" on the Company's
Statement of Consolidated Earnings. 

OTHER -- In addition to those matters separately disclosed above, the Company
has incurred in the regular course of business certain other commitments and
contingent liabilities including, among other things, (1) personal injury
lawsuits, (2) indemnity and other hold harmless agreements, (3) environmental
remediation liabilities, (4) product liability claims, and (5) claims by
disgruntled employees. These various commitments and contingent liabilities, in
the judgment of management, do not total more than 10% of current assets and
will not result in losses that would materially affect the Company's
consolidated balance sheet. However, because the Company's results of operations
vary considerably with construction activity and other factors, it is at least
reasonably possible that charges for contingencies in the future could,
depending on when they occur and how large they are relative to results of
operations or cash flows for a particular period, have a material negative
impact on the Company's results of operations or cash flows for that period.

[18] CAPITAL STOCK:

In June 1998, the shareholders of the Company voted to amend the Company's
Restated Articles of Incorporation, as amended, to increase the authorized
number of shares of common stock. The authorized capital stock of the Company
comprises 200,000,000 shares of Common Stock, $1.25 par value and 10,000,000
shares of Preferred Stock, $.05 par value. American Stock Transfer & Trust
Company, serves as the registrar and transfer agent for the Common Stock.

COMMON STOCK

At December 31, 1998, there were approximately 39,849,000 shares of common stock
issued and approximately 38,683,000 shares of common stock outstanding and held
of record by approximately 4,268 shareholders, and approximately 4.7 million
shares were reserved for future issuance upon exercise of options granted under
employee benefit plans and stock issued under phantom stock plans. The Company
paid a quarterly dividend of $.10 per share of common stock from March 1997 to
September 1998. In December 1998, the quarterly dividend was increased to $.15
per share of common stock.

COMMON STOCK REPURCHASE PROGRAM

On November 22, 1996, the Board of Directors approved a common stock repurchase
program under which the Company was authorized to repurchase up to 1.5 million
shares of the Company's outstanding common stock. As of December 31, 1997,
1,166,000 shares of common stock had been purchased in open market transactions
at a cost of $46.3 million. Medusa's Board of Directors also previously
authorized the purchase of outstanding common shares under which Medusa, in its
discretion, made open market purchases from time to time. Medusa purchased
approximately 500,000 shares of its then outstanding common stock for $19.2
million in 1997 and 455,000 shares for $13.6 million during 1996. On March 17,
1998, both companies' Board of Directors cancelled their respective common stock
repurchase program and neither company repurchased shares of common stock in
1998.


SHAREHOLDER RIGHTS PLAN

The Company has a shareholder rights plan pursuant to which each holder of
common stock has one Right per share to purchase initially a Unit consisting of
one one-hundredth of a share of Preferred Stock, Junior Participating Series C,
at a purchase price of $60 per Unit, subject to adjustment. The Rights are not
exercisable generally until the earlier of (1) ten days following a public
announcement that a person or group has acquired, or obtained the right to
acquire, beneficial ownership of 15% or more of the outstanding shares of common
stock or (2) ten business days following the commencement of a tender offer or
exchange offer that would result in a person's becoming an acquiring person.

<PAGE>   31

With certain exceptions, in the event a person becomes an acquiring person, each
Right (except those held by the acquiring person or certain related persons,
which become void) will then entitle the holder to purchase a number of shares
of common stock of the Company having a current market price of twice the
purchase price. In the event that any time on or after the stock acquisition
date, (1) the Company is acquired in a merger or other business combination,
with certain exceptions, or (2) 50% or more of the Company's assets or earning
power is sold or transferred, each Right (except those held by the acquiring
person or certain related persons, which become void) will then entitle the
holder to purchase a number of shares of common stock of the acquiring company
(or in certain cases its controlling person) having a current market price of
twice the purchase price. 

The Rights expire at the close of business on March 14, 2001. At any time until
ten days following a stock acquisition date, the Company may redeem the Rights
in whole, but not in part, at a price of $.01 per Right, payable, at the option
of the Company, in cash, shares of common stock, or other consideration. The
provisions of the shareholder rights plan are intended to discourage, or may
have the effect of discouraging, partial tender offers, front-end loaded
two-tier tender offers and certain other types of coercive takeover tactics and
inadequate takeover bids and to encourage persons seeking to acquire control of
the Company first to negotiate with the Company. The Company believes that these
provisions on balance provide benefits to the Company's shareholders by
enhancing the Company's potential ability to negotiate an improvement in terms
with the proponent of an unfriendly or unsolicited proposal to take over or
restructure the Company.

PREFERRED STOCK

The Board of Directors is authorized to designate series of preferred stock and
fix the powers, preferences and rights of the shares of such series and the
qualifications, limitations or restrictions on these powers, preferences and
rights. 

SERIES A AND B PREFERRED STOCK -- In 1987, the Company issued 1,999,998 shares
of Preferred Stock, $.70 Cumulative Convertible Series A. In 1988, the Company

[19] STOCK OPTION PLANS:

EMPLOYEE STOCK OPTION PLANS -- As of December 31, 1998, there are two stock
option plans for officers and certain key employees of the Company. Both the
1987 Stock Option Plan and the 1989 Stock Option Plan each had initially
available for award up to 2,000,000 shares of the Company's common stock. In
June 1998, shareholders of the Company voted to approve an amendment to the
Company's 1989 Stock Option Plan to increase the number of shares of Company
Common Stock available for grant to 5 million. As of December 31, 1998,
1,980,047 options for the 1987 Plan and 1,716,680 options for the 1989 Plan had
been awarded. The Employee Compensation and Benefits Committee of the Board of
Directors may permit any option granted under the plans to be exercisable
immediately upon the date of grant or at any time thereafter. However, no option
granted under the plans may be exercised within the first six months after the
date of grant except in the event of the death or disability of the optionee.
Since August 1994, options granted have typically become exercisable over four
equal annual installments at the end of each year after the date of grant of
continued employment with the Company. Options granted are exercisable at the
fair market value of the stock at the date of grant and typically expire ten
years from the date of grant. Unoptioned shares available for grant as of
December 31, 1998 were 19,953 and 3,283,320 under the 1987 Plan and 1989 Plan.

MEDUSA LONG-TERM INCENTIVE PLAN -- In conjunction with the Medusa merger,
options granted under the Medusa long-term incentive plan to purchase
approximately 592,000 shares of Medusa common stock were converted into options
to purchase approximately 522,000 shares of Company common stock. The options
are exercisable at the fair market value of the stock at the date of grant,
adjusted for the merger conversion ratio, and expire ten years from the date of
grant. Of these 522,000 options, approximately 195,200, all of which are
exercisable, remain outstanding as of December 31, 1998. 

NON-EMPLOYEE DIRECTORS' PLAN -- Under the 1991 Nonqualified Stock Option Plan
for Non-Employee Directors, options for a total of up to 400,000 shares of the
Company's common stock are available for grant to directors of the Company who
are not employed by the Company or any of the Company's subsidiaries. The 1991
Director's Plan provides that: (1) options to acquire 10,000 shares of the
Company's common stock are automatically granted to each non-employee director
on the date of the director's first election to the Board, (2) 2,000 options are
automatically granted to each non-employee director on the date of each annual
meeting of shareholders where he or she continues to serve as a director of the
Company, (3) options granted are exercisable at the fair market value of the
common stock at the date of grant and expire ten years from the date of grant,
(4) all options granted are exercisable six months after the date of the grant,
and (5) upon the termination of service as a director on the Board by a
non-employee director who is eligible for benefits under the Southdown, Inc.
Directors' Retirement Plan, any of such director's options outstanding as of the
date of such termination of service on the Board shall be exercisable for ten
years from the date of grant of such options. As of December 31, 1998, a total
of 224,000 options had been awarded under the 1991 Directors' Plan. Unoptioned
shares available for grant as of December 31, 1998 under the 1991 Director's
Plan were 176,000.

Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" encourages, but does not require companies to record compensation
cost for employee stock-based compensation plans at fair value. Because of the
inexact and subj ective nature of deriving the fair value of stock-based
compensation, the Company has adopted the disclosure-only provisions of SFAS No.
123 and continues to account for stock-based compensation as it has in the past
using the intrinsic value method prescribed in Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees." Accordingly, because
the exercise price of stock-based compensation equals the market price of the
underlying stock on the date of grant, no compensation expense has been
recognized for the Company's stock plans.

As permitted by SFAS No. 123, the Company has estimated the pro forma fair value
of its stock-based compensation for disclosure purposes by using the
Black-Scholes model, a generally recognized option pricing model. Had
compensation cost for the Company's stock-based compensation plans been
determined based on the fair value at the grant date for awards consistent with
the provisions of SFAS No. 123, the Company's net earnings and diluted earnings
per share would have been reduced by $3 million or $.08 per share, $3 million or
$.08 per share and $2.2 million or $.07 per share in 1998, 1997 and 1996. The
pro forma fair value of options at date of grant was estimated using the
following assumptions:

The Black-Scholes model was originally developed for use in estimating the fair
value of traded options, which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the use of subjective
assumptions including the expected life of the option and expected stock price
volatility. Because the Company's 


<PAGE>   34

stock-based compensation has characteristics different from those of traded
options and because of the subjective nature of certain assumptions used the
Company can not guarantee that the weighted average fair value amounts reflected
in the table above will be achieved. Also, the computed pro forma impact only
includes the effects of grants since January 1, 1994. Because it is likely that
additional options will be granted in future years and will vest ratably, the
reported pro forma results are not necessarily representative of the effects on
reported pro forma results for future years.

PHANTOM STOCK PLAN -- Effective January 1, 1997, the Board of Directors adopted
the Phantom Stock and Deferred Compensation Plan for Non-Employee Directors,
which was approved by the shareholders at the 1997 Annual Meeting. This plan
calls for the non-employee directors to receive on a deferred basis, in lieu of
cash, 50% of their monthly directors' fees in fair market value of Common Stock.
The fair market value is determined based upon the average of the high and low
prices of the Common Stock on the last New York Stock Exchange trading day of
the month the fee is payable. The non-employee director may elect to receive on
a deferred basis his total monthly fee in fair market value of Common Stock. The
plan defers the recognition of compensation by the director by deferring the
issuance of Common Stock to the director until he or she leaves the Board. The
director's account will also be credited with fair market value of Common Stock
equal to cash dividends on Common Stock that would have been received had the
Common Stock been issued when earned. A total of 250,000 shares of Common Stock
have been reserved for issuance under this plan. As of December 31, 1998,
approximately 1,300 shares, and 13,000 stock equivalent units have been issued.

MEDUSA RESTRICTED STOCK AWARD PLANS -- Prior to the merger, Medusa had
restricted stock award plans, which provided for awards of common stock to
officers and non-employee directors of Medusa. These awards were subject to
resale restrictions. The terms of the plans provided the resale restrictions
would lapse in the event of a change in control of Medusa and, accordingly, the
recipients of these restricted stock awards were allowed to sell their shares in
conjunction with the merger transaction. Compensation expense of $8.5 million
related to these plans has been included in estimated merger related transaction
costs. (See also Note 3 of Notes to Consolidated Financial Statements.)

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

Southdown, Inc. is one of the largest producers of cement in the U.S. The
Company operates twelve portland cement manufacturing plants located in Alabama,
southern California, Colorado, Florida, Georgia, Kentucky, Michigan, Ohio,
Pennsylvania, Tennessee and Texas, plus an extensive network of cement
distribution terminals. The Company also mines, processes, and sells
construction aggregates and specialty mineral products in the eastern half of
the U.S. and in southern California. In addition, the Company markets
ready-mixed concrete products in two of its largest cement markets, southern
California and Florida. The discussion and analysis that follows reflects
management's assessment of the financial condition and results of operations of
Southdown and subsidiary companies and should be read in conjunction with the
audited consolidated financial statements on pages 32 through 64. 

Earnings from continuing operations for 1998 increased 22% to $186.9 million or
$4.81 per diluted share, excluding a one-time, after tax charge of $61.9 million
or $1.59 per share related to the merger with Medusa Corporation. The Company
produced record 1998 revenues and record operating earnings, before acquisition
charges, of $1.185 billion and $301.6 million, respectively, which represent
increases of 8% and 21% compared with 1997 results. Net earnings for 1998 were
$123.4 million, or $3.18 per share, on a diluted basis. Net earnings included an
after tax loss of $1.6 million, $.04 per share, from discontinued operations.
For 1997, the Company reported net earnings of $153.7 million or $3.94 per
share, diluted. Prior year results have been restated to include the results of
Medusa's operations. 

All three of the Company's operating segments showed improvements. In absolute
dollars, the Cement segment showed the largest improvement, rising $43.7 million
or 16% to $311 million in operating earnings for 1998 compared with $267.3
million in 1997. Even excluding the $3.7 million gain realized in 1998 on the
sale of certain Florida west coast facilities, the Concrete Products segment
showed the largest percentage improvement, increasing 77% to $16.8 million in
operating earnings compared with $9.5 million for 1997. The Aggregates segment
rose 21% to $25 million in operating earnings for 1998 compared with $20.6
million for 1997. 

Net earnings for 1997 were significantly higher than the $112.2 million, $2.88
per share, diluted, earned in 1996. Net earnings for 1996 included an after-tax
extraordinary charge of $13.3 million, $.33 per diluted share, for prepayment
premium and other costs incurred on the early retirement of 14% Senior
Subordinated Notes and the Medusa 6% Convertible Subordinated Notes.
Consolidated revenues in 1997 improved 11% over 1996 because of higher sales
prices in all three of the Company's operating segments and improved cement
sales volumes and aggregate sales volumes. The year-over-year improvement in
operating results includes a 17% increase in Cement segment earnings. An almost
75% increase in Aggregate segment earnings and a 34% reduction in interest
expense also contributed to the year-over-year improvement, offsetting a 22%
decline in the Concrete Products segment and higher Corporate overhead. Interest
expense in 1997 declined compared with 1996, because of the refinancing of the
Company's 14% Notes with 10% Senior Subordinated Notes in March 1996 and lower
borrowings on Medusa's revolving credit facility.

SEGMENT OPERATING EARNINGS

CEMENT -- The cement operating margin rose to 37.4% as average selling prices
were up at all of the Company's plants in 1998, with an overall increase of
4.9%, or $3.37 per ton. The Company's largest plant, located in Victorville,
California, led the cement group in both pricing and demand growth as robust
construction activity was apparent in all of the plant's principal marketing
regions of southern California, Arizona and Nevada. Overall, demand was strong
in the Company's principal markets as total cement sales volumes increased
approximately 3% for the year. The Company expects cement demand to remain
strong in 1999, primarily related to anticipated increases in Federal and state
infrastructure spending. While average cement prices are expected to rise in
1999, the rate of increase is expected to slow as U.S. cement prices approach
competitive world pricing levels. 

Average cement unit costs of sales in 1998 increased only $.18 per ton, or .4%,
as a result of a 447,000 ton or 4.6% increase in clinker production levels and
lower fuel and raw materials costs, partially offset by increased power and
maintenance costs.

Cement segment operating earnings in 1997 were 17%, or almost $39 million better
than the $228.4 million earned in 1996. The segment had a 448,000 ton increase
in 1997 cement sales volumes and a 5.3% improvement in average sales prices over
1996. The higher 1997 sales volumes and sales prices reflected continuation of
growing demand for cement, which began in the early 1990's.

The table below shows sales volumes and average unit sales prices, unit
manufacturing and other plant operating costs and unit margins relating to
cement plant operations for the past three years. Manufacturing and other plant
operating costs include fixed and variable manufacturing costs, cost of
purchased cement, selling expenses, plant general and administrative costs,
other plant overhead and miscellaneous costs.

CONCRETE PRODUCTS -- Concrete Products earnings improved to $20.5 million in
1998 from the $9.5 million earned in 1997. Results for 1998 include $5.7 million
in gains on asset sales compared with $2 million in gains from such sales in
1997. Concrete Products revenues for 1998 were essentially unchanged from the
prior year as a 4.8% improvement in average selling prices offset a
weather-impacted decline in sales volumes in the Florida operations. Both the
southern California and Florida operations benefited from a manageme nt
reorganization in 1998, which has reduced overhead costs and improved operating
efficiencies. 

The Concrete Products segment's operating earnings for 1997 were 22% lower than
the $12.2 million earned in 1996. Earnings were lower compared with the prior
year primarily because of a 28% decline in the Florida concrete block
operations. The higher cost of purchased inventory and the loss of a large
customer hurt block operations in 1997. Despite improved ready-mixed concrete
sales prices in California, 1997 operating results from the ready-mixed concrete
operation declined because of higher raw material and strike-related costs.

operating costs and unit margins relating to the Company's ready-mixed concrete

    $4 million, $3.5 million and $4.7 million of operating earnings for 1998, 
    1997 and 1996, respectively.

AGGREGATES -- Operating earnings for the Aggregates segment increased to $25
million in 1998, up 21% compared with 1997. Revenues for the segment increased
24% for 1998 compared with 1997 as both sales volumes and average sales prices
improved. The Company sold one million more tons of aggregates in 1998 than in
1997. The improvement resulted primarily from higher sales volumes at both the
Midwest and the southern California construction aggregates operations.
Specialty minerals volumes increased because of the full year contribution of
two operations acquired in late 1997, but poor weather during the 1998 peak
Spring gardening season adversely impacted lawn and garden products sales
volumes. Average sales prices increased 17% due, in part, to a favorable mix of
aggregate products sold during 1998 compared with 1997. Year-over-year operating
costs for the segment increased an average of $1.13 per ton resulting in a net
10% margin improvement for 1998. 

Aggregates segment net sales for 1997 rose 46% over 1996. Approximately 32% of
the increase was attributable to three acquisitions made during the year.
Including the acquisitions, unit volume increased 27% with a 26% average unit
price increase. Without the acquisitions, 1997 aggregate sales from the eastern
quarries and the specialty aggregate operations increased 13% over 1996 with a
14% increase in volume and essentially flat prices. Partial realization of price
increases implemented during the previous twelve months and higher sales volumes
favorably impacted 1997 earnings from the California construction aggregates
operation. 

The table below shows sales volumes, average unit sales price and cost data and
unit operating profit margins relating to the Company's aggregates operations.
Operating costs include variable and fixed plant costs, delivery, selling,
general and administrative and miscellaneous operating costs.

</TABLE>

CORPORATE OVERHEAD, INTEREST INCOME AND INCOME TAX EXPENSE -- Corporate overhead
consists primarily of costs attributable to the Company's Houston, Texas office
and miscellaneous other income and expense items. These costs are generally not
allocated to the business segments. Corporate overhead expenses increased in
1998 by $6.7 million, or 14% compared with last year, primarily because of the
transfer of various operating segment administrative functions to the Corporate
office and because of merger related transition costs, higher consulting fees
for special marketing and tax studies and increased incentive compensation
resulting from the Company's

record performance. The Company expects a 12-15% decline in Corporate overhead
costs in 1999, primarily related to cost savings associated with the Medusa
merger. Corporate overhead expenses for 1997 exceeded 1996 by $9 million, or
23%, primarily because of higher administrative costs.

Interest income in 1998 was $5.9 million compared with $3.3 million in 1997 as a
result of the significantly higher levels of invested cash maintained throughout
1998, particularly in the fourth quarter. Interest income in 1997 was
essentially level with 1996. 

The effective tax rate, which includes state taxes, is greater than the federal
statutory rate of 35% for 1998 because of the non-deductibility for tax purposes
of certain of the merger related transaction costs. (See also Note 13 of Notes
to Consolidated Financial Statements.) The Company expects a slight reduction in
the effective tax rate for 1999. The Company's effective tax rate was lower than
the federal statutory rate for both 1997 and 1996, primarily because of the
favorable impact of permanent differences related to statutory depletion in
excess of cost depletion applicable to the Company's limestone mining
operations.

LIQUIDITY AND CAPITAL RESOURCES

The Company's business segments require a large amount of capital, particularly
the Cement segment, which has been expanding its production capacity. When these
capital requirements cannot be met internally, the Company borrows under its
outstanding credit facilities or sells debt or equity securities. The Company
has a $200 million revolving credit facility that matures in June 2002. The
facility permits standby letters of credit up to a maximum of $95 million in
lieu of borrowings. At December 31, 1998, there were no borrowings and $67
million in letters of credit outstanding under the revolving credit facility,
leaving $133 million of unused capacity. The Company is in compliance with the
financial ratios and covenants in the revolving credit agreement and the
Company's 10% Senior Subordinated Notes Indenture. 

In connection with the Medusa merger, the Company in May 1998 amended its
revolving credit agreement to permit (1) the Medusa merger, (2) the assumption
of the existing indebtedness of Medusa of up to $100 million, and (3) the
guarantee of a $15 million lease obligation associated with the Medusa merger.
The Company also obtained a release of the bank group's liens on the collateral
security, including the security interest in five of the Company's cement plants
and the Company's interest in the Kosmos joint venture. In December 1998, the
Company again amended its credit agreement to permit (1) the contribution or
other transfer of certain California assets to certain existing and newly
created wholly-owned subsidiaries of the Company and (2) the merger of Medusa
entities with and into the Company.

CASH FLOWS

In 1998, the Company generated $212.6 million in cash provided by operating
activities. This was only 10% less than the $237 million generated in 1997,
despite the payment of approximately $59.3 million of Medusa acquisition costs
during 1998. At the end of 1998, the balance of cash and cash equivalents was
$143.8 million, an increase of almost $45 million from the prior year balance.
Likewise, 1997 cash provided by operations was approximately 10% greater than in
1996 because of a significant increase in earnings from continuing operations,
partially offset by the timing of payments on normal trade, tax and other
obligations.

<PAGE>   38

Net cash used for investing activities in 1998 was $119.4 million. Expenditures
in 1998 included $116.4 million of additions to property, plant and equipment,
offset by $13.9 million in proceeds from miscellaneous asset sales and $7.9
million in net proceeds from the maturity of short-term investments. Investing
activities in 1997 of $108.4 million included approximately $94.6 million of
capital additions and the acquisition of two specialty minerals operations for
$30.2 million. Investing activities for 1996 included approximately $78.8
million of capital expenditures and $6.2 million in acquisitions.

Net cash used in financing activities in 1998 was $48.3 million, primarily
utilized to reduce long-term debt by $33.6 million and pay dividends of $19.4
million on capital stock. In the third quarter of 1997, all of the outstanding
shares of the Company's Series D Preferred Stock were converted into
approximately 2.6 million shares of common stock. Conversion of the Series D
Preferred Stock has improved the Company's annual cash flow by the difference
between preferred and common stock dividends of approximately $3.9 million per
year. In 1997, net cash used in financing activities was $100.1 million,
primarily related to the repurchase of $59.9 million of common stock and the
payment of $22.9 million of dividends on capital stock. Both Medusa and the
Company discontinued the stock repurchase programs in early 1998.

The Company utilized the proceeds from the issuance of $125 million of 10% Notes
combined with other borrowings in 1996 to repurchase $125 million of the 14%
Notes and to pay the related prepayment premium and other costs. The Company
used cash in 1996 to repurchase $19.2 million of common stock and pay $26.7
million of dividends on capital stock. In 1996, the Company converted
substantially all of the shares of its Series A Preferred Stock and Series B
Preferred Stock into 3.3 million shares of common stock. This conversion of
preferred stock into common stock reduced fixed charges and improved the
Company's annual cash flow by the difference between preferred and common stock
dividends of approximately $3.5 million per year. In 1996, $26.7 million of
Medusa's 6% convertible subordinated notes were converted into .7 million shares
of Medusa common stock. The conversion of the Medusa notes reduced annual
interest payments by approximately $1.6 million. The 1996 exercise of 1.25
million warrants to purchase Company common stock provided $20 million in cash
from financing activities.

CHANGES IN FINANCIAL CONDITION

The change in the financial condition of the Company between December 31, 1997
and December 31, 1998 reflected the utilization of short-term investments plus
internally generated cash flow to fund capital expenditures, Medusa acquisition
costs, working capital requirements and capital stock dividends. Accounts and
notes receivable increased reflecting the additional sales activity occurring in
late 1998 relative to the prior year. The increase in inventories reflects
higher clinker and cement production levels during 1998 compared with the prior
year. The decrease in goodwill reflects the continuing amortization of goodwill
and the reclassification of $11.2 million to property, plant and equipment based
on final appraisals received related to 1997 acquisitions. The increase in other
long-term assets reflects higher prepaid pension costs. Accounts payable and
accrued liabilities increased because of the timing of payments on normal trade
and other obligations. The decrease in the long-term portion of postretirement
benefit obligation reflects the continuing amortization of the Company's
unrecognized prior service credit and unrecognized net gain related to the
benefit plan.

<PAGE>   39

CAPITAL EXPENDITURES

The Company invested approximately $116 million in property, plant and equipment
in 1998 including approximately $102 million for the Cement operations, $2
million for Concrete Products and $8 million for Aggregates. It is projected
that the Company's capital expenditures in 1999 will increase to slightly more
than $200 million. Capital expenditures for the Cement segment are expected to
exceed $175 million in 1999 (before consideration of joint venture partner
capital contributions) as a result of several capacity expansion projects in
progress at the Company's Louisville, Kentucky, Clinchfield, Georgia, and
Victorville, California plants. Capital expenditures for the Concrete Products
and Aggregates segments in 1999 are budgeted primarily for projects relating to
replacement and modernization of equipment, quarry development and expansion,
and for environmental compliance projects. Budgeted 1999 capital expenditures
include approximately $11 million related to compliance with environmental
regulations. The Company believes its expected cash flow from operating
activities will be sufficient to fund these capital expenditures. If necessary,
the Company has sufficient borrowing capacity available under its revolving
credit facility to supplement these expected future operating cash flows.

KNOWN EVENTS, TRENDS AND UNCERTAINTIES

ENVIRONMENTAL MATTERS

The Company is subject to a wide range of federal, state and local laws,
regulations and ordinances dealing with the protection of human health and the
environment. These laws regulate water discharges and air emissions, as well as
the handling, use and disposal of hazardous and non-hazardous waste materials.
These laws also create a shared liability by responsible parties for the cost of
cleaning up or correcting releases to the environment of designated hazardous
substances. The Company, therefore, may have to remove or mitigate the
environmental effects of the disposal or release of certain substances at the
Company's various operating facilities or elsewhere. 

Several of the Company's previously and currently owned facilities have become
the subject of various local, state or federal environmental proceedings and
inquiries. While some of these matters have been settled, others are in their
preliminary stages and may not be resolved for years. The information developed
to date on these matters is not complete. Based on what it knows currently,
however, the Company does not believe it will be required to spend significantly
more on these matters than the amounts already recorded in the Company's
financial statements. However, until all (1) environmental studies and
investigations, (2) remediation work, (3) negotiations with other parties that
may be responsible, or (4) litigation against other potential sources of
recovery have been completed, it is impossible for the Company to determine the
ultimate cost that it might incur to resolve these environmental matters. 

The Company or its predecessors have conducted industrial operations at the
Company's cement manufacturing facilities for many years. As was common in the
industry, the Company in the past disposed of various materials used in its
cement manufacturing, concrete products and aggregates operations in onsite and
offsite facilities. Today, some of these materials may be classified as
hazardous substances. In addition, revisions to air quality standards may result
in increased capital and operational expenses for a broad range of industrial
sectors, including portland cement manufacturing. Yet another evolving issue of
potential significance to the Company is global warming and the international
accord to move toward greenhouse gas stabilization or reduction after the turn
of the century. 

<PAGE>   40

While the Company commits substantial resources to complying with the laws and
regulations concerning the protection of human health and the environment, the
Company considers this to be an integral part of its business. Management
believes that the Company's current procedures and practices for handling and
management of materials are generally consistent with industry standards and
legal requirements and that the Company takes appropriate precautions to protect
employees and others from harmful exposure to hazardous materials. However,
because of the complexity of operations and legal requirements, there can be no
assurance that past or future Company operations will not result in operational
errors, violations, remediation liabilities or claims by employees or others
alleging exposure to toxic or hazardous materials. Regulatory changes,
enforcement activities or other factors could alter environmental compliance
costs at any time. In addition, future changes in regulatory requirements
related to the protection of human health and the environment may require the
Company and others engaged in industrial operations to modify various facilities
and alter methods of operations at costs that may be substantial. Management,
however, does not believe that the Company would be placed at a competitive
disadvantage with respect to other companies engaged in similar lines of
business in the U.S.

OTHER CONTINGENCIES

IMPORT COMPETITION -- During the 1980s there was a surge of unfairly priced
cement and clinker imports into the U.S. In response, U.S. industry
participants, including the Company, filed antidumping petitions in 1989 against
imports from Mexico and, in following years, against imports from Japan and
Venezuela. After investigations into the matter, the International Trade
Commission (ITC) and the Department of Commerce (Commerce) decided in favor of
the petitioners and issued an antidumping order against Mexican cement and
clinker in 1990 and against Japanese cement and clinker in 1991. In addition, in
February 1992, Commerce suspended investigations of dumped and subsidized
imports of cement and clinker from Venezuela, based upon the Venezuelan cement
producers' agreement to change their prices to stop the dumping of gray portland
cement and clinker from Venezuela into the U.S. and the Venezuelan government's
agreement not to subsidize the Venezuelan cement producers. 

As a result of legislation passed by the U.S. Congress in 1994, Commerce and the
ITC will conduct "sunset" reviews of the antidumping orders and suspension
agreements beginning in August 1999 to determine whether they should be revoked
or remain in effect for another five years. The Company expects the sunset
review process to take longer than a year and believes there are strong
arguments and evidence to convince Commerce and the ITC to leave the antidumping
remedies in effect. In addition to the sunset reviews, decisions by Commerce, by
NAFTA binational panels or by the U.S. Courts on appeal of Commerce decisions in
future administrative reviews could meaningfully reduce the existing antidumping
duties. If any of these events were to happen, there could be a material
negative impact on the Company's results of operations. 

U.S. imports of foreign cement began to increase in the mid-1990's as the use of
cement in the U.S. began to recover. The Portland Cement Association has
estimated that imports represented approximately 22% of cement used in the U.S.
during 1998 as compared with approximately 18% in 1997 and 16% in 1996. Unlike
the imports during the 1980's, however, most of the recent imports have provided
an additional source of supply rather than disrupting the market with unfair
prices. During most of the recent period of strong demand, the prices of cement
imports rose. The increase is attributable, at least in part, to the influence
of the outstanding antidumping orders and suspension agreements. While the
average cost of imported cement rose during 1998, the cost of cement imports
from some countries, particularly those from Southeast Asia, have declined.
Moreover, independently owned cement import operators could undertake to
construct new import facilities and begin to purchase large quantities of
low-priced 

<PAGE>   41

cement from countries not yet subject to antidumping orders, such as those in
Asia, which could compete with domestic producers. The introduction of
low-priced imported cement from such sources could have a negative impact on the
Company's results of operations.

YEAR 2000 COMPLIANCE -- The Company, like most companies relying on automated
data processing and other microprocessor controlled equipment, is faced with the
task of assuring that these systems are capable of distinguishing 21st century
dates from 20th century dates and that they will continue to function properly
after the Year 2000. The Company is actively engaged in, but has not yet
completed, reviewing, correcting and testing all of its Year 2000 compliance
issues. To determine the Company's current exposure, corporate personnel, along
with an outside consulting firm specializing in Year 2000 problems, conducted a
formal assessment to quantify the task of becoming compliant. 

Based on the results of that assessment, the Company is currently at various
stages in the processes of modifying or replacing some of its internally
developed and purchased software and its manufacturing process control systems
and assessing the need to modify or replace embedded microprocessor controlled
equipment. The Company is also taking steps designed to verify the Year 2000
readiness of key third party suppliers, service providers and customers by
contacting them and attempting to assess and validate the compliance efforts of
these third party sources. As of December 31, 1998, the Company believes it has
made significant progress toward resolving its Year 2000 compliance issues. The
Company believes that the majority of its financial applications are now Year
2000 compliant, or soon will be. The Company has shifted its main focus to
embedded processors in cement, concrete products and aggregates facilities and
equipment and assessing potential Year 2000 compliance problems with the
Company's material external suppliers of goods, services and data. The Company
is conducting internal investigations of its manufacturing plant control
systems, its mobile equipment and its other field equipment and devices with
embedded microprocessor controls. In some, but not all instances, the Company
has already upgraded or replaced time sensitive programs or microprocessors. The
Company expects to have all modifications completed by mid-1999. 

Costs incurred relating to making the Company Year 2000 compliant are expensed
in the period in which they are incurred. The Company currently estimates that
the total additional cost to comply with Year 2000 requirements will be
approximately $2 million to $3 million, including the cost of outside
consultants, accelerated software replacement beyond the normal upgrade cycle
and the replacement or modification of equipment with embedded microprocessor
controls. It is not certain, however, that these esti mates are correct or that
Year 2000 compliance can be fully achieved. The Company expects that it will not
experience a disruption of its operations, but actual results could differ
greatly from the Company's plans. Some of the specific problem areas that might
cause material differences to occur are (1) the availability and cost of
personnel trained in this area, (2) the ability to identify and correct all
relevant computer codes, (3) the ability to identify and correct non-complying
microprocessors embedded in other digitally controlled equipment, and (4) the
significant degree of interdependence with third party suppliers, service
providers and customers. Conditions outside of the Company's control such as
problems in the transportation, postal, banking or telecommunication systems,
may have a material disruptive effect on the Company's ability to process
orders, effect delivery of materials or finished goods, invoice customers or
disburse or receive funds. 

With respect to the Company's own internal operations, the most reasonably
likely worst case scenario would be a shut down of a production system because
of some unforeseen problem with an automated monitoring or control device. The
Company intends to formulate a Year 2000 contingency plan by mid-1999 to address
risks and possible 

<PAGE>   42

countermeasures that are expected to include plans for manual intervention of
control systems and equipment and may also entail replacement of certain
equipment on an emergency basis. It may not be possible, however, to adequately
plan for all contingencies. The Company is presently unable to determine the
impact on its business if it and the other companies on which it relies do not
achieve Year 2000 compliance, or that the impact will not have a material
adverse affect on the Company's financial condition or results of operations.

KOSMOS JOINT VENTURE SEVERANCE TAX AUDIT -- Kosmos Cement Company is a
partnership operated and 75% owned by the Company. In late 1997, the State of
Kentucky proposed a deficiency assessment against Kosmos for severance tax
payments related to limestone mined at its Battletown, Kentucky quarry. The
total assessment is approximately $3.7 million, including penalty and interest.
Kosmos is contesting the assessment. Kosmos met with the Kentucky Revenue
Cabinet in January 1998 to discuss the disputed assessments. Discussions are
still ongoing and the Company is unable to evaluate whether an unfavorable
outcome is either probable or remote. 

In addition to limestone mined for the production of cement, Kosmos mines
limestone specifically for use by a local electric utility company. The Company
believes that, under the terms of a supply agreement, the utility company is
responsible for severance taxes on limestone provided to it. A major portion of
the Kentucky severance tax assessment relates to this specifically mined
limestone. For the amounts not paid by the local electric utility, the Company
would indirectly bear 75% of any settlement and legal costs through its
ownership interest in Kosmos. 

CLAIMS FOR INDEMNIFICATION -- The Mineral Management Service of the Department
of the Interior claimed that the Company's former oil and gas subsidiary, Pelto
Oil Company, owed royalties on two separate gas contract settlement payments
that Pelto received. When the Company sold Pelto in 1989, the Company agreed to
protect the purchaser from any future claims related to these two payments. In a
1998 letter, the MMS advised that it was withdrawing its royalty claim in the
amount of $1.35 million on one of the settlement payments because of a 1997
court ruling, which prohibited further claims against the current owner of Pelto
and that owner's affiliates. The MMS, however, reserved its right to possibly
reassert the claim at a later date. 

The Company also disagrees with MMS' claim that an unspecified amount of
royalties are owed on the second gas contract settlement payment of $5.9
million. If one or both of MMS' claims against Pelto are ultimately successful,
the Company could have liability for royalties, plus late payment charges in
amounts which are not currently determinable. Such expenditures would result in
a charge to discontinued operations. 

DISCONTINUED ENVIRONMENTAL SERVICES SEGMENT -- The Company has both given and
received environmental and other indemnifications related to properties the
Company previously owned. A few courts have held that such promises to protect
other parties from loss for environmental liabilities are unenforceabl e. At
present, the Company is not able to estimate the extent of contamination,
remediation cost or recoverability of cost from prior owners, if any, regarding
these discontinued operations, except as noted below. 

In late 1994 and the first quarter of 1995, the Company learned of some soil and
groundwater contamination at its former Alabama hazardous waste processing
facility. Although the Company sold the facility in April 1995, the Company
agreed to keep some liability for soil and groundwater contamination at the
facility prior to that time. The Company's investigation has not yet determined
the extent of the contamination or what sort of cleanup, if any, will be
required. It is too early to determine the amount of the Company's exposure to
loss with any degree of certainty. The Company has agreed to remediate the soil
and groundwater contamination at the Alabama facility to the extent required by
law, but it has filed a lawsuit against the former owner of the facility. Claims
against the prior owner and other potentially responsible parties could
significantly reduce or eliminate the Company's own loss exposure. 


<PAGE>   43

OTHER -- In addition to those matters separately disclosed above, the Company
has incurred in the regular course of business certain other commitments and
contingent liabilities including, among other things, (1) personal injury
lawsuits, (2) indemnity and other hold harmless agreements, (3) environmental
remediation liabilities, (4) product liability claims, and (5) claims by
disgruntled employees. These various commitments and contingent liabilities, in
the judgment of management, do not total more than 10% of current assets and
will not result in losses that would materially affect the Company's
consolidated balance sheet. However, because the Company's results of operations
vary considerably with construction activity and other factors, it is at least
reasonably possible that charges for contingencies in the future could,
depending on when they occur and how large they are relative to results of
operations or cash flows for a particular period, have a material negative
impact on the Company's results of operations or cash flows for that period.

INFLATION AND CHANGING PRICES

Inflation has become less of a factor in the U. S. economy as the rate of
increase has moderated during the last several years. The Consumer Price Index
rose approximately 1.6% in 1998, and approximately 2% in 1997 and 3% in 1996.
The impact of inflation and changing prices on the Company's net sales and
revenues and on net earnings, however, has been significant as a general firming
of cement and concrete prices throughout the industry during the three years
ended December 31, 1998 has enabled the Company to increase its Cement segment
per unit profit margin in each successive year. The Company expects the rate of
price increase to slow as U.S. cement prices approach competitive world pricing
levels.

MARKET RISK

The Company does not enter into derivatives or other financial instruments for
trading or speculative purposes. Because of the short duration of the Company's
investments, changes in market interest rates would not have a significant
impact on their fair value. For expected maturity dates and average interest
rates of long-term debt, see Note 12 of Notes to Consolidated Financial
Statements, "Long-term Debt- Annual Total Maturities of Long-term Debt". See
also Note 2 of Notes to Consolidated Financial Statements for the impact of the
new accounting standard for derivative instruments and hedging activities.

DISCLOSURE REGARDING FORWARD LOOKING STATEMENTS

This document includes forward-looking statements within the meaning of Section
27A of the Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended. The Company based these statements on current
expectations, estimates and projections about the general economy and the
Company's lines of business. These statements are generally identifiable by
phrases containing words such as "expects," "believes," "anticipates,"
"estimates" or similar expressions. Statements related to future performance
involve certain assumptions, risks and uncertainties, many of which are beyond
the control of the Company, and cannot be guaranteed. 

Although the Company believes that the expectations reflected in such forward
looking statements are based upon reasonable assumptions, it can not say with
certainty that what it expects will actually happen. Important factors that
could cause actual results to differ materially from the Company's expectations
include, among others, (1) significant excess cement production capacity in
other parts of the world, specifically Asia, (2) foreign and domestic price
competition, (3) the loss or material negative change of existing antidumping
orders, (4) cost effectiveness, (5) changes in environmental regulation, and (6)
general economic and market conditions such as interest rates, the availability
of capital and the cyclical nature of the construction industry. The Company
cautions the reader to consider these disclosures when reading the
forward-looking statements included in this report. Subsequent written and oral
forward looking statements made by the Company or by persons acting on behalf of
the C ompany are completely qualified by these cautionary disclosures.

SELECTED QUARTERLY FINANCIAL DATA 
(UNAUDITED)

The Company's businesses are seasonal to the extent that construction activity
and hence, the demand for cement, concrete products, and construction
aggregates, tends to diminish during the winter months and other periods of
inclement weather. Specialty aggregates lawn and garden products have a peak
selling season in the Spring of the year. The following tables show certain
unaudited selected quarterly financial data for each of the last two years.
Gross profit shown is revenues less operating expense and depreciation expense
relating to cost of sales. Depreciation expense relating to cost of sales was
$15.9 million, $18 million, $15.2 million and $16.9 million in each of the
quarterly periods of 1998. Depreciation expense relating to 1997 cost of sales
was $14.3 million, $14.1 million, $14.7 million and $15.7 million in each of the
quarterly periods. Because of the dilutive effect of the acquisition charge in
the second quarter, the sum of the earnings per share for the four quarters of
1998 does not equal the earnings per share for the twelve months ended December
31, 1998.
