Item 1.  BUSINESS

Lafarge Corporation (the "Registrant"), a Maryland corporation, is engaged in
the production and sale of cement and ready-mixed concrete, aggregates,
asphalt, concrete blocks and pipes and precast and prestressed concrete
components in the United States and Canada. The Registrant believes that it is
one of the largest producers of cement and construction materials in North
America.  The Registrant is also engaged in road building and other
construction using many of its own products. Its wholly-owned subsidiary,
Systech Environmental Corporation ("Systech"), provides waste-derived fuels and
alternative raw materials to cement plants for use in kilns across North
America.  The Registrant's Canadian operations are carried out by Lafarge
Canada Inc. ("LCI"), a major operating subsidiary of the Registrant.  Lafarge
Coppee S.A. ("Lafarge Coppee"), a French corporation, and certain of its
affiliates own a majority of the Registrant's outstanding voting securities.
The terms "Registrant", "LCI" and "Systech", as used in this Annual Report,
include not only Lafarge Corporation, LCI, Inc. and Systech Environmental
Corporation, respectively, but also their respective subsidiaries and
predecessors, unless the context indicates otherwise.

The Registrant manufactures and sells various types of portland cement, which
is widely used in most types of residential, institutional, commercial and
industrial construction. The Registrant also manufactures and sells a variety
of special purpose cements. At December 31, 1993 the Registrant operated 15
full-production cement manufacturing plants with a combined rated annual
clinker production capacity of approximately 12.3 million tons and two cement
grinding facilities. The Registrant sells cement primarily to manufacturers of
ready-mixed concrete and other concrete products and to contractors throughout
Canada and in many areas of the United States. During 1993 the Registrant's
cement operations accounted for 47 percent of consolidated net sales, after the
elimination of intracompany sales, and 76 percent of consolidated income from
operations.

Management believes that LCI is the largest producer of concrete-related
building materials in Canada, where approximately 73 percent of the
Registrant's construction materials facilities were located at December 31,
1993. The U.S. construction materials operations are located primarily in
Texas, Louisiana, Ohio, Pennsylvania, Illinois, New York, Missouri, Kansas and
Washington. The Registrant's significant construction materials activities
include the manufacture and sale of ready-mixed concrete, construction
aggregates, other concrete products and asphalt and road construction. The
Registrant has operations at approximately 420 locations including ready-mixed
concrete plants, crushed stone and sand and gravel sites, concrete product and
asphalt plants. During 1993 the Registrant's construction materials operations
accounted for 53 percent of consolidated net sales, after the elimination of
intracompany sales, and 24 percent of consolidated income from operations.

At December 31, 1993 Systech operated eight facilities at cement plants in the
U.S. and Canada, including five plants that are owned by the Registrant.
Systech processed approximately 66 million gallons of supplemental fuel in
1993.  Systech's results of operations are included in the results of the
Registrant's construction materials operations.

The executive offices of the Registrant are located at 11130 Sunrise Valley
Drive, Suite 300, Reston, Virginia 22091, and its telephone number is (703)
264-3600.


                      (A)  GENERAL DEVELOPMENT OF BUSINESS

In 1970, Lafarge Coppee acquired control of Canada Cement Lafarge Ltd.
(now LCI) which was Canada's largest cement producer.  In 1974, LCI extended
its cement manufacturing operations into the United States through a joint
venture which operated three cement plants in the United States.  Following the
termination of the joint venture in 1977, the Registrant (which was
incorporated in Maryland in 1977 under the name Citadel Cement Corporation of
Maryland) operated two of these U.S. cement plants.  In 1981, a subsidiary of
the Registrant acquired the stock of General Portland Inc. ("General
Portland"), the second largest cement producer in the U.S.  In 1983, a
corporate reorganization was effected which established the Registrant as the
parent company of LCI and General Portland (General Portland was merged into
the Registrant in 1988), and the Registrant's name was changed to Lafarge
Corporation.  In 1986, the Registrant purchased substantially all the assets of
National Gypsum Company's Huron Cement Division, consisting of one cement
plant, 13 cement terminals and related distribution facilities around the Great
Lakes.  Also in 1986, the Registrant acquired Systech.  During 1989, 1990 and
1991, the Registrant significantly expanded its U.S. construction materials
operations through acquisitions, the largest of which included 32 plant
facilities in five states and substantial mineral reserves acquired from
Standard Slag Holding Company headquartered in Ohio.  The Registrant acquired
Missouri Portland Cement Company, Davenport Cement Company and certain related
companies and assets in 1991.  This acquisition included three cement plants
and 15 cement distribution terminals located in the Mississippi River Basin,
more than 30 ready-mixed concrete and aggregate operations and the assets of a
chemical admixtures business.


Restructuring

In December 1993 the Registrant announced the restructuring of its North
American business units to be more efficient and cost competitive.  The
Registrant will consolidate 11 regional operating units into six in its two
main business lines, cement and construction materials.  To increase
organizational efficiency, the Registrant is reducing management layers,
eliminating duplicative administrative functions, and standardizing procedures
and information systems.  Manufacturing and distribution facilities will not be
materially affected by the reorganization.





                                      I-2

<PAGE>   4
As of January 1, 1994, the Registrant's new North American organization
included three regions for construction materials:  Western, based in Calgary,
Alberta; Eastern, based in Toronto, Ontario; and U.S., based in Canfield, Ohio.
Similarly, the cement group was divided into Western, Eastern and U.S. regions,
with office locations in Calgary; Montreal, Quebec; and Southfield, Michigan,
respectively.  A technical services group will be maintained at the
Registrant's research center in Montreal and Corporate headquarters will remain
in Reston, Virginia.

See page II-7 of Item 7 and page II-35 of Item 8 of this Annual Report for
further discussion regarding the restructuring.


Sale of Demopolis Cement Operations

Effective February 1, 1993 the Registrant sold its cement plant in Demopolis,
Alabama.  The sale included the Registrant's 810,000 ton single- kiln plant and
related assets, seven cement distribution terminals and two terminal leases in
the southeastern United States, a cement grinding plant and several barges.
The purchase price was approximately $50 million in cash.  The Registrant used
the proceeds from the sale to repay debt.  The gain from the sale was
immaterial.  Systech continues to supply the Demopolis plant with waste-derived
fuels.


               (B)  FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The Registrant's operations are closely integrated.  For reporting purposes,
the Registrant currently has only one industry segment, which includes the
manufacture and sale of cement, ready-mixed concrete, precast and prestressed
concrete components, concrete blocks and pipes, aggregates, asphalt and
reinforcing steel.  In addition, the Registrant is engaged in road building and
other construction utilizing many of its own products.  Its subsidiary,
Systech, provides waste-derived fuels and alternative raw materials for use in
cement kilns.  Financial information with respect to the Registrant's product
lines and geographic segments is set forth under Item 7 Management's Discussion
of Income on pages II-3 through II-19, Management's Discussion of Cash Flows on
pages II-20 and II-21 and Item 8 - Consolidated Financial Statements and
Supplementary Data on pages II-45 and II-46 of this Annual Report.

The Registrant's business is affected significantly by seasonal variations in
weather conditions, primarily in Canada and the northern United States.
Information with respect to quarterly financial results is set forth in Item 8
page II-54 of this Annual Report.

                     (C)  NARRATIVE DESCRIPTION OF BUSINESS


Cement Product Line

The Registrant manufactures and sells in Canada (through its subsidiary LCI)
and in the United States various types of portland cement, a basic construction
material manufactured principally from limestone and clay or shale.  Portland
cement is the essential binding ingredient in concrete, which is widely used in
most types of residential, institutional, commercial and industrial
construction.  In addition to normal portland cement, the Registrant
manufactures and sells a variety of special purpose cements, such as high early
strength, low and moderate heat of hydration, sulphate resistant, silica fume,
masonry and oilwell cement.

At December 31, 1993 the rated annual clinker production capacity of the
Registrant's operating cement manufacturing plants was approximately 12.3
million tons with about 5.2 million tons in Canada and approximately 7.1
million tons in the United States.  The Canadian Portland Cement Association's
"Plant Information Summary Report" dated December 31, 1992 shows that the
Canadian capacity is the largest of the cement companies in Canada and
represented approximately 31 percent of the total active industry clinker
production capacity in that country.  This same report for the U.S. at December
31, 1992 shows that the Registrant's operating cement manufacturing plants in
the United States accounted for an estimated nine percent of total U.S. active
industry clinker production capacity.


Cement Plants

The following table indicates the location, types of process and rated annual
clinker production capacity (based on management's estimates) of each of the
Registrant's operating cement manufacturing plants at December 31, 1993.  The
total clinker production of a cement plant might be less than its rated
capacity due principally to product demand and seasonal factors.  Generally, a
plant's cement production capacity is greater than its clinker production
capacity.

All of the Registrant's cement plants are fully equipped with raw grinding
mills, kilns, finish grinding mills, environmental protective dust collection
systems and storage facilities.  Each plant has facilities for shipping by rail
and by truck.  The Richmond, Alpena, Bath, Davenport, Sugar Creek and Joppa
plants have facilities for transportation by water.  The Exshaw and Brookfield
plants and the Kamloops limestone and cinerite quarries are located on sites
leased on a long-term basis.  The Registrant owns all other plant sites.  The
Registrant believes that each of its producing plants is in satisfactory
operating condition.

At December 31, 1993, the Registrant owned cement grinding plants for the
processing of clinker into cement at Fort Whyte, Manitoba; Edmonton, Alberta;
Saskatoon, Saskatchewan; Montreal East, Quebec and Superior, Wisconsin.  The
Edmonton, Montreal East, Saskatoon and Superior grinding plants have been
shutdown for several years as cement grinding has not been cost effective at
these locations.  These plants were used during 1993 for the storage of cement.
The Registrant also owns a cement regrind plant and terminal facilities at
Tampa, Florida which include facilities for receiving cement by water.  The
Registrant owns clinker producing plants which have been shut down in Havelock,
New Brunswick, Ft. Whyte, Manitoba and Metaline Falls, Washington.

During 1987 the Registrant re-opened the two million ton clinker capacity
Alpena plant with restructured low-cost operations utilizing waste- derived
fuels supplied by Systech.  The Alpena plant was acquired by the Registrant in
December 1986.  In January 1989 the Registrant announced a multi-year,
two-phase modernization and expansion program for the Alpena plant.  The first
phase of this project, substantially completed in 1990, included approximately
$55 million for equipment and related support systems and between $10 and $15
million in facility upgrades.  The second phase of the modernization program
totalling approximately $26 million is currently underway and will involve
additional improvements to the plant's raw materials handling and storage
facilities.  The facility upgrade and modernization program is expected to
reduce operating costs and increase the plant's rated annual cement production
capacity to 2.5 million tons.

In January 1991, as part of the Missouri Portland/Davenport acquisition, the
Registrant acquired three cement plants located in the Mississippi River Basin:
a 1,150,000-ton clinker capacity cement plant located in Joppa, Illinois, a
858,000-ton clinker capacity cement plant located in Davenport, Iowa and a
482,000-ton clinker capacity cement plant located near Kansas City, Missouri
(Sugar Creek).  Total 1993 clinker production from these three dry-process
cement plants was 2,225,000 short tons, or 89 percent of capacity.  The three
cement plants acquired in the Missouri Portland/Davenport acquisition increased 
the Registrant's annual clinker production capacity by 25 percent.


The Manufacturing Process

The Registrant manufactures cement by a closely controlled chemical process
which begins with the crushing and mixing of calcium carbonates, argillaceous
material (clay, shale or kaolin) and silicates (sand).  Once mixed, the crushed
raw materials undergo a grinding process, which mixes the various materials
more thoroughly and increases fineness in preparation for the kiln.  This
mixing and grinding process may be done by either the wet or the dry method.
In the wet process, the materials are mixed with water to form "slurry", which
is heated in kilns, forming a hard substance called "clinker".   In the more
fuel-efficient dry process, the addition of water and the formation of slurry
are eliminated, and clinker is formed by heating the dry raw materials.  In the
preheater process, which provides further fuel efficiencies, the dry raw
materials are preheated by air exiting the kiln, and part of the chemical
reaction takes place prior to entry of the materials into the kiln.  In the
pre-calciner process, an extension of the preheater process, heat is applied to
the raw materials, increasing the proportion of the chemical reaction taking
place prior to the kiln and, as a result, increasing clinker production
capacity.  After the addition of gypsum, the clinker is ground into an
extremely fine powder called cement.  In this form, cement is the binding agent
which, when mixed with sand, stone or other aggregates and water, produces
either concrete or mortar.

The raw materials required to manufacture cement are obtained principally from
operations which are owned by the Registrant or in which it has long-term
quarrying rights.  These sources are located close to the manufacturing plants
except for the Joppa and Richmond quarries which are located approximately 70
and 80 miles, respectively, from the plant site.  Each cement manufacturing
plant except New Braunfels is equipped with rock crushing equipment.  At New
Braunfels and Richmond, the Registrant owns the reserves, but does not
currently quarry them.  The Registrant purchases limestone for Richmond from a
local source and for New Braunfels from Parker Lafarge, Inc. an affiliate of
the Registrant.  At Whitehall, Joppa and Kamloops the Registrant sub-contracts
the quarry operations.

Fuel represents a significant portion of the cost of manufacturing cement.  The
Registrant has placed special emphasis on becoming, and has become, more
efficient in its sourcing and use of fuel.  Dry process plants generally
consume significantly less fuel per ton of output than do wet process plants.
At year-end approximately 79 percent and 89 percent of the Registrant's clinker
production capacity in Canada and the United States, respectively, used the dry
process.

As an additional means of reducing energy costs, most plants are now equipped
to convert from one form of fuel to another with very little interruption in
production, thus avoiding dependence on a single fuel and permitting the
Registrant to take advantage of price variations between fuels.

The use of waste-derived fuels supplied by Systech has also resulted in
substantial fuel cost savings to the Registrant.  At December 31, 1993, the
Registrant used industrial waste materials obtained and processed by Systech as
fuel at three of the Registrant's United States cement plants.

Waste-derived fuels supplied by Systech constituted approximately 10 percent of
the fuel used by the Registrant in all of its cement operations during 1993.

In August 1991, the Registrant's U.S. cement plants which utilize hazardous
waste-derived fuels became subject to a substantial new federal permit program
known as the Resource Conservation and Recovery Act ("RCRA") boiler and
industrial furnaces (BIF) regulations.  In August 1992, these plants submitted
certifications of compliance for the emission limits established under these
regulations.  In Canada, the St. Constant and Brookfield plants have submitted
permit applications to use hazardous waste as supplemental fuel.  These
applications are in the public review phase.

The following table shows the possible alternative fuel sources of the
Registrant's cement manufacturing plants in the United States and Canada at
December 31, 1993.

Marketing

Cement is sold by the Registrant primarily to manufacturers of ready-mixed
concrete and other concrete products and to contractors throughout Canada and
in many areas of the United States.  The states in which the Registrant had the
most significant U.S. sales in 1993 were Texas and Wisconsin.  Other states in
which the Registrant had significant sales include Florida, Illinois, Indiana,
Iowa, Kansas, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, New
Jersey, New York, North Dakota, Ohio, Pennsylvania, Tennessee and Washington.

The provinces in Canada in which the Registrant had the most significant sales
of cement products were Ontario and Quebec, which together accounted for
approximately 44 percent of the Registrant's total Canadian cement shipments in
1993.  Approximately 35 percent of the Registrant's cement shipments in Canada
were made to affiliates.

The Registrant sells cement to several thousand unaffiliated customers.  No
single unaffiliated customer accounted for more than 10 percent of the
Registrant's cement sales during 1993, 1992 or 1991.  Sales are made on the
basis of competitive prices in each market area, generally pursuant to
telephone orders from customers who purchase quantities sufficient for their
immediate requirements.  The amount of backlog orders, as measured by written
contracts, is normally not significant.

At December 31, 1993 sales offices in the United States were located in or near
New Orleans, Louisiana; Buffalo, New York; Dallas, Texas; Tampa, Florida; Fort
Wayne, Indiana; Whitehall, Pittsburgh and Hamburg,





                                      I-8

Pennsylvania; East Cambridge, Massachusetts; Chicago, Illinois; Cleveland,
Ohio; Lansing, Michigan; Milwaukee, Wisconsin; Seattle and Spokane, Washington;
Minneapolis, Minnesota; Kansas City , Missouri; Davenport, Iowa; Valley City
and Grand Forks, North Dakota and Nashville, Tennessee.

At December 31, 1993 sales offices in Canada were located in Dartmouth, Nova
Scotia; Moncton, New Brunswick; Quebec City and Montreal, Quebec; Toronto,
Ontario; Winnipeg, Manitoba; Regina and Saskatoon, Saskatchewan; Calgary and
Edmonton, Alberta; and Kamloops and Vancouver, British Columbia.

Distribution and storage facilities are maintained at all cement manufacturing
and finishing plants and at approximately 100 other locations including five
deep water ocean terminals.  These facilities are strategically located to
extend the marketing areas of each plant.  Because of freight costs, most
cement is sold within a radius of 250 miles from the producing plant, except
for waterborne shipments which can be shipped economically considerably greater
distances.  Cement is distributed primarily in bulk but also in paper bags.

The Registrant utilizes trucks, rail cars and waterborne vessels to transport
cement from its plants to distribution points or directly to customers.
Transportation equipment is owned, leased or contracted for as required.  In
addition, some customers in the United States  make their own transportation
arrangements and take delivery of cement at the manufacturing plant or
distribution point.


Construction Materials Product Line

The Registrant is engaged in the production and sale of ready-mixed concrete,
aggregates, asphalt, precast and prestressed concrete, concrete block, concrete
pipe and other related products.  The Registrant is also engaged in highway and
municipal paving and road building work.  During 1993, 1992 and 1991 no single
customer accounted for more than 10 percent of the Registrant's construction
materials sales.

LCI is the only producer of ready-mixed concrete and construction aggregates in
Canada that has operations extending from coast to coast.  Ready-mixed concrete
plants mix controlled portions of cement, water and aggregates to form concrete
which is sold primarily to building contractors and delivered to construction
sites by mixer trucks.  In addition, management believes that LCI is one of the
largest manufacturers of precast concrete products and concrete pipe in Canada.
These products are sold primarily to contractors engaged in all phases of
construction activity.  The Registrant owns substantially all of its
ready-mixed concrete, concrete products and aggregates plants and believes that
all such plants are in satisfactory operating condition.





                                      I-9

<PAGE>   11
The Registrant owned or had a majority interest in 311 construction materials
facilities in Canada at December 31, 1993.  Of these, 118 are ready-mixed
concrete plants concentrated in the Provinces of Ontario (where approximately
one-half of the plants are located), Alberta, Quebec and British Columbia.  The
Registrant also owns ready-mixed concrete plants in New Brunswick, Nova Scotia,
Saskatchewan and Manitoba.  The Registrant owns 112 construction aggregates
facilities in Canada, more than half of which are located in Ontario.  The
other aggregates facilities are located in Alberta, Saskatchewan, British
Columbia, Quebec, Manitoba, New Brunswick and Nova Scotia.  The Registrant's 29
Canadian asphalt facilities are also concentrated primarily in Ontario with the
remaining plants in Alberta, Nova Scotia, New Brunswick and Quebec.  The
Registrant owns a total of 52 precast and prestressed concrete, concrete block
and concrete pipe plants and miscellaneous other construction materials
operations in Ontario (where approximately one-half of the plants are located),
Alberta, British Columbia, Manitoba, Quebec and New Brunswick.

In the U.S., the Registrant owned or had a majority interest in 117
construction materials facilities at year end.  Of these, 54 are ready- mixed
concrete plants concentrated in Texas, Missouri, and to a lesser extent,
Louisiana, Ohio and Kansas.  Of the Registrant's 44 U.S.  construction
aggregates facilities, 12 were in Ohio, 14 in Texas, five in Pennsylvania, with
the remainder located in West Virginia, New York, Louisiana, Michigan,
Missouri, and Washington.  Two of the Registrant's six U.S. asphalt plants were
located in New York and four in Texas.  The Registrant owned a total of 13
concrete paving stone, road paving, soil cement, concrete paving and
miscellaneous other construction materials operations located in Ohio,
Michigan, Texas, Pennsylvania, Missouri and New York.

In addition, the Registrant has minority interests in a number of smaller
companies primarily engaged in the manufacture and sale of ready- mixed
concrete, other concrete products and aggregates in Canada and the U.S.

Systech Environmental Corporation provides waste-derived fuels and alternative
raw materials for use in cement kilns.  Using a technology called
co-processing, Systech is able to use high BTU value waste as a fuel substitute
for coal, natural gas and petroleum coke in heating the cement kiln.
Co-processing preserves natural resources and serves as a safe and efficient
method to manage selected waste.  In addition, co- processing makes the product
more competitive by reducing fuel cost, which represents about 15 percent of
the expense of cement manufacturing.


Research, Development and Engineering

The Registrant is involved in research and development work through its own
technical services and laboratories and through its participation in the
Portland Cement Association.  In addition, Lafarge Coppee, LCI





                                      I-10

<PAGE>   12
and the Registrant are parties to agreements relating to the exchange of
technical and management expertise under which the Registrant has access to the
research and development resources of Lafarge Coppee.  Research is directed
toward improvement of existing technology in the manufacturing of cement,
concrete and related products as well as the development of new manufacturing
techniques and products.  Systech is also engaged in research and development
in an effort to further develop the technology to handle additional waste
materials.  Research and development costs, which are charged to expense as
incurred, were $7.3 million, $8.1 million and $7.5 million for 1993, 1992 and
1991, respectively.  This includes amounts accrued for technical services
rendered by Lafarge Coppee to the Registrant, under the terms of the agreements
discussed above of $4.8 million during 1993, $5.3 million during 1992 and $5.4
million during 1991.


Capital Expenditures and Asset Dispositions

The Registrant's business is relatively capital-intensive.  During the
three-year period ended December 31, 1993 the Registrant invested approximately
$209 million in capital expenditures, principally for the modernization or
replacement of existing equipment.  Of this amount, approximately 42 percent
related to cement operations and 58 percent to construction materials
operations.  During the same period, the Registrant also invested approximately
$31 million in various acquisitions that expanded its market and product lines
which primarily related to the Registrant's construction materials operations.

For a discussion on the sale of the Demopolis cement operations see "General
Development of Business - Sale of Demopolis Cement Operations".

Cement terminal facilities in St. Louis, Missouri and Houston, Texas were
shutdown in February 1993.  The Registrant intends to sell the land on which
these terminals and related assets are located.

In September 1992, the Registrant sold the assets of Conchem, a chemical
admixtures business located in the United States and Canada.  The divestiture
included seven facilities engaged in the production and sale of admixture and
specialty products for the concrete and construction industry throughout North
America.  The U.S. assets had been acquired as part of the Missouri
Portland/Davenport acquisition in January 1991 (see "General Development of
Business").  During 1993, 1992 and 1991 the Registrant disposed of various
surplus properties; however, there were no other material divestments of
property, plant and equipment during these three years.

In December 1993 the Registrant's Construction Materials operations purchased a
plant from Koch Industries, Inc. for grinding iron blast furnace slag into slag
cement at Spragge, Ontario.  In April 1993 the Registrant entered into a joint
venture, Richvale-York Block Inc. with another block producer to carry on its
concrete block business in the Greater Metropolitan Toronto area.  The
Registrant is the majority





                                      I-11

<PAGE>   13
shareholder in this joint venture which owns two modern block plants that are
strategically located in this market.


Environmental Matters

The Registrant's operations, like those of other companies engaged in similar
businesses, involve the use, release/discharge, disposal and clean-up of
substances regulated under increasingly stringent federal, state, provincial
and/or local environmental protection laws.  The major environmental statutes
and regulations affecting the Registrant's business and the status of certain
environmental enforcement matters involving the Registrant are discussed in
Item 7 of this Annual Report in the "Environmental Matters" section of
Management's Discussion and Analysis beginning on page II-15.  Additionally,
certain enforcement matters are described in Item 3 (Legal Proceedings) of this
Annual Report.


Employees

As of December 31, 1993, the Registrant and its subsidiaries employed
approximately 7,400 individuals of which 4,640 were hourly rated wage workers.
Approximately 1,530 of these hourly employees were engaged in the production of
portland cement products and approximately 3,110 were employed in the
Registrant's construction materials operations. Salaried employees totalled
approximately 2,750. These employees generally perform work in administrative,
managerial, marketing, professional and technical endeavors. Overall, the
Registrant considers its relations with employees to be satisfactory.

- - - U.S. CEMENT OPERATIONS

The majority of the Registrant's approximately 2,200 U.S. hourly employees are
represented by labor unions. During 1993, labor agreements were renegotiated at
the Buffalo, Iowa and Fredonia, Kansas cement plants (including distribution
terminals in Fort Worth, Texas and Westlake, Louisiana). Five other terminal
labor agreements expired and new agreements were reached during 1993: Waukegan,
Illinois; Duluth, Minnesota; Superior, Wisconsin; Toledo; Ohio and Oswego, New
York. Four cement plant labor agreements will expire in 1994: Whitehall,
Pennsylvania; Sugar Creek, Kansas; Paulding, Ohio; and Balcones, Texas. The
labor agreement for Whitehall was renewed for a period of 46 months in early
1994.  Effective February 1, 1993, the Registrant completed the sale of its
Demopolis, Alabama cement plant and surrounding sales and distribution
operations (see "General Development of Business - Sale of Demopolis Cement
Operations" above). In addition, terminal facilities in St. Louis, Missouri and
Houston, Texas were shut down in February. The Registrant intends to sell the
land on which these terminals and related assets are located. In late 1993, it
was announced that in connection with the restructuring of the Registrant's
North American business units (see "General Development of Business -
Restructuring" above), the administrative operations of the Southern Region
office in





                                      I-12

<PAGE>   14
Dallas would be consolidated into one U.S. region based in Southfield,
Michigan. This transition is expected to be completed by June 1994.

- - - U.S. CONSTRUCTION MATERIALS OPERATIONS

The Registrant's approximately 1,715 U.S. construction materials employees
consist of approximately 1,200 hourly employees and 515 salaried employees. In
1993, divestiture of aggregate and construction operations in southern Ohio,
northern Kentucky and central Illinois resulted in a reduction of 119 employees
(96 hourly and 23 salaried). In the Registrant's Sullivan Lafarge operations in
New York, the closure of six plants resulted in the severance of 110 hourly
employees. In the Registrant's Standard Lafarge division, a labor agreement
covering six plants was negotiated in 1993, and four single site labor
agreements covering a total of approximately 105 employees will expire in 1994.
Although a work stoppage is possible at one of these sites, it is expected that
operations will continue without interruption.

At the Registrant's Kurtz Lafarge division, the labor agreement for ready-mixed
concrete truck drivers expired in May 1993 for the plants located west of the
Missouri River. Negotiations were unsuccessful and 35 drivers went on strike
July 15, 1993 and remain on strike.  Replacement drivers have been hired and
the affected plants are now operating. The labor agreement for the drivers on
the east side of the Missouri River expired on March 15, 1994 and negotiations
for a new contract have begun. A work stoppage could occur but is not expected.
The Kurtz Lafarge operations which are based in Sedalia, Missouri negotiated a
new labor agreement in 1993. Labor agreements relating to operations based in
Waynesville and Kansas City, Missouri will expire in 1994.

- - - CANADIAN CEMENT OPERATIONS

Substantially all of the approximately 540 Canadian cement hourly employees are
covered by labor agreements. The Kamloops, British Columbia plant's labor
agreement was renewed in 1993 for a period of two years.  On January 7, 1994 a
lock-out was initiated by the Registrant for its 112 hourly employees at the
Exshaw, Alberta plant and it remains in effect as of the date of this Report.
The plant has continued to operate without interruption, and this situation
will not have a material effect on the Registrant's financial condition or
results of operations in 1994. The Bath, Ontario plant's labor agreement
expired at the end of 1993 and was renewed for 23 months. Labor agreements for
the Woodstock, Ontario plant and the St. Constant, Quebec plant will expire in
1994 and are expected to be renegotiated without any work stoppage. Also,
several terminal labor agreements will expire in 1994.





                                      I-13

<PAGE>   15
- - - CANADIAN CONSTRUCTION MATERIALS OPERATIONS

Employees working in the Canadian construction materials operations totalled
approximately 2,825 at the end of 1993 with approximately 1,915 hourly
employees and 910 salaried employees. In western Canada, twelve labor
agreements were renegotiated in 1993, and it is anticipated that 24 labor
agreements will be renegotiated during 1994. In eastern Canada, sixteen labor
agreements were renegotiated.


Competition

The competitive marketing radius of a typical cement plant for common types of
cement is approximately 250 miles except for waterborne shipments which can be
economically transported considerably greater distances.  Cement, concrete
products and aggregates and construction services are sold in competitive
markets.  These products and services are obtainable from alternate suppliers.
Vigorous price, service and quality competition is encountered in each of the
Registrant's primary marketing areas.

The Registrant's operating cement plants located in Canada represented an
estimated 31 percent of the rated annual active clinker production capacity of
all Canadian cement plants at December 31, 1992.  The Registrant is the only
cement producer serving all regions of Canada.  The Registrant's largest
competitor in Canada accounted for approximately 23 percent of rated annual
active clinker production capacity.  The Registrant's operating cement plants
located in the United States at December 31, 1992 represented an estimated nine
percent of the rated annual active clinker production capacity of all U.S.
cement plants.  The Registrant's three largest competitors in the United States
accounted for 14, seven and five percent, respectively, of the rated annual
active clinker production capacity.  The preceding statements regarding the
Registrant's ranking and competitive position in the cement industry are based
on the U.S. and Canadian Portland Cement Industry: "Plant Information Summary
Report" dated December 31, 1992.

The Registrant also encounters competition from foreign cement producers,
especially in its markets in the southern coastal portion of the United States.

Item 2.  PROPERTIES

Information set forth in Item 1 of this Annual Report, insofar as it relates to
the location and general character of the principal plants, mineral reserves
and other significant physical properties owned in fee or leased by the
Registrant, is incorporated herein by reference in answer to this Item 2.

All of the Registrant's cement plant sites (active and closed) and quarries
(active and closed), as well as terminals, grinding plants and miscellaneous
properties, are owned by the Registrant free of major encumbrances, except the
Exshaw and Brookfield plants and the Kamloops limestone and cinerite quarries.

Title to the Brookfield plant site is held by Industrial Estates Limited, a
Crown corporation of the Province of Nova Scotia, in connection with assistance
provided by the Province in financing the cost of construction of the plant.
The site is leased by LCI at rentals sufficient to repay principal and interest
on the loan.  The lease, which expires in 1998, grants LCI an option to acquire
title to the plant site during the term of the lease upon payment of the unpaid
principal amount.  During 1993, LCI exercised its option to acquire title to
the Brookfield plant by paying the unpaid principal.  Title to the property is
in the process of being transferred to the Registrant.

The Exshaw plant is built on land leased from the Province of Alberta.  The
original lease has been renewed for a 42-year term commencing in 1992.  Annual
payments under the lease are presently based on a fixed fee per acre.

The Kamloops plant, as well as the gypsum quarry which serves this plant, is on
land owned by the Registrant.  The limestone and cinerite quarries are on land
leased from the province of British Columbia until March 2022.

Limestone quarry sites for the cement manufacturing plants in the United States
are owned and are conveniently located near each plant except for the Joppa
plant quarry which is located approximately 70 miles from the plant site.  At
December 31, 1993, the Registrant also owned substantial reserves which
previously supplied raw materials to former cement production facilities which
are located at Miami, Tampa, Fort Worth and Dallas.  The Fort Worth plant
facility is now a cement terminal.  The Tampa plant is now operated as a cement
grinding and distribution facility.

LCI's quarrying rights for limestone in the Canadian provinces of Manitoba, New
Brunswick, Quebec, Nova Scotia, Ontario, Alberta and British Columbia, are held
under quarry leases, some of which require annual royalty payments to the
provincial authorities.  Management of the Registrant estimates that its
limestone reserves for the cement plants currently producing clinker will be
adequate to permit production at present capacities for at least 20 years.
Other raw materials, such as clay, shale, sandstone and gypsum, are either
obtained from reserves





                                      I-18

<PAGE>   20
owned by the Registrant or are purchased from suppliers and are readily
available.

Deposits of raw materials for the Registrant's aggregate producing plants are
located on or near the plant sites.  These deposits, due to their varying
nature, are either owned by the Registrant or leased upon terms which permit
orderly mining of reserves.

Item 3.        LEGAL PROCEEDINGS

During 1989 and 1990, CSX Transportation, Inc., Metro-North Commuter Railroad
Company, National Railroad Passenger Corp., Peerless Insurance Company and
Massachusetts Bay Transit Authority (the "Railroads") filed actions against
Lone Star Industries Inc. and affiliates ("Lone Star") for damages resulting
from its fabrication and sale of allegedly defective concrete railroad ties to
the Railroads. The Registrant and LCI have been named in third party actions in
which Lone Star is claiming indemnity for liability to the Railroads, for
damages to its business and for costs and losses suffered as a result of the
Registrant and LCI supplying allegedly defective cement used by Lone Star in
the fabrication of the railroad ties. The damages claimed total approximately
$226.5 million. The Registrant denied the allegations and vigorously defended
against the lawsuits (the "Lone Star Case"). During September and October 1992,
Lone Star entered into agreements with all five plaintiff Railroads settling
their claims regarding the Lone Star Case for an amount totalling approximately
$66.7 million. These settlements have been submitted to and approved by the
United States Bankruptcy Court for the Southern District of New York which is
handling the Lone Star bankruptcy. Lone Star commenced trial in November 1992
in its third party complaint against the Registrant and LCI seeking indemnity
for the Railroads' claims in addition to its own claim for business
destruction. A jury verdict in this case reached in December 1992 awarded Lone
Star $1.2 million as damages. Both Lone Star and the Registrant and LCI have
appealed the trial court verdict to the United States Court of Appeals for
Fourth Circuit. A decision is expected in the near future.

In late 1990 Nationwide Mutual Insurance Company ("Nationwide"), one of the
Registrant's primary insurers during the period when allegedly defective cement
was supplied to Lone Star by the Registrant, filed a complaint for declaratory
judgement against the Registrant, several of its affiliates and eleven other
liability insurers of the Registrant (the "Coverage Suit").  The complaint
seeks a determination of all insurance coverage issues impacting the Registrant
in the Lone Star Case. The Registrant has answered the complaint,
counterclaimed against Nationwide, cross-claimed against the co-defendant
insurers and filed a third party complaint against 36 additional insurers. In
December 1991, the Registrant and Nationwide entered into a settlement
agreement pursuant to which Nationwide settled its claim in the Coverage Suit
and, among other things, paid the Registrant a portion of past due defense
expenses in the Lone Star Case, promised to pay its proportion of continuing
defense expenses therein and to post the entire remaining aggregate limits of
its policies as reserves to be used in the Lone Star Case, if necessary.
Virtually all of LCI's Canadian insurers involved in the Coverage Suit filed
motions for summary judgment. In January 1993, the court denied all of the
insurers' summary judgment motions. In January 1994 the Registrant filed
motions for partial summary judgment regarding the insurers' defense
obligations and regarding the reasonableness of fees and expenses included in
the defense of the Lone Star Case. In addition, the Registrant filed a motion
to strike the designation of several expert witnesses of the insurers. The
Registrant





                                      I-20

<PAGE>   22
believes that it has substantial insurance coverage that will respond to a
large portion of defense expenses and liability, if any, in the Lone Star Case.

During 1992, a number of owners of buildings located in Eastern Ontario, Canada
most of whom are residential homeowners, filed actions in the Ontario Court
(General Division) against Bertrand & Frere Construction Company Limited and a
number of other defendants seeking damages as a result of allegedly defective
footings, foundations and floors made with ready-mixed concrete supplied by
Bertrand. The largest of these cases involves claims by approximately 99
plaintiffs owning 53 homes, a 20-unit condominium building and a municipal
building. Together, these plaintiffs are claiming approximately Cdn. $40
million against Bertrand, each plaintiff seeking Cdn. $200,000 for costs of
repairs and loss of capital value of their respective home or building, Cdn.
$200,000 for punitive and exemplary damages and Cdn. $20,000 for hardship,
inconvenience and mental distress, together with interest and costs. Other
owners, owning a total of 13 buildings (of which 11 are residential homes),
have instituted similar suits against Bertrand and, based on the information
available at this time, these claims total approximately Cdn. $9 million. As of
the end of December 1993, LCI has been served with third- or fourth-party
claims by Bertrand in all but one of the referenced lawsuits. Bertrand is
seeking indemnity for its liability to the owners as a result of the supply by
LCI of allegedly defective flyash. LCI also supplied cement to Bertrand. It is
expected that Bertrand will file a third-party claim against LCI in the other
case as well.  LCI has delivered its statements of defense. The discoveries are
to begin in February 1994.  LCI has denied liability and will defend the
lawsuits vigorously. The Registrant believes it has substantial insurance
coverage that will respond to defense expenses and liability, if any, in the
said lawsuits.

The Registrant has received a notice of violation and/or a complaint with
respect to each of its three cement plants that use hazardous waste derived
fuel alleging violations of the Boiler and Industrial Furnaces ("BIF")
regulations of the federal Resources Conservation and Recovery Act ("RCRA").
These notices of violation and complaints were issued by the U.S. Environmental
Protection Agency ("EPA") with respect to the plants, located in Fredonia,
Kansas and Paulding, Ohio and by the State of Michigan, which has been
delegated BIF enforcement authority by the EPA, with respect to the plant
located in Alpena, Michigan.  Although the details of each notice of violation
or complaint are specific to the particular plant, the major recurring issue
has been the existence or adequacy of the plant's waste analysis plan to ensure
compliance with the established allowable emission limits and feed rates.  The
State of Michigan has proposed a penalty of $979,750 for the Alpena plant and
the EPA has proposed penalties of $619,800 for the Paulding plant and
$1,200,474 for the Fredonia plant.  The Registrant has submitted a response to
each notice of violation and complaint setting forth certain defenses and
factual information and has had meetings with the EPA and Michigan state
officials to discuss the alleged violations and possibilities of settlement.
At this time, it is unknown whether the Registrant will be able to settle any
or all of these matters or whether





                                      I-21

<PAGE>   23
one or more adjudicatory proceedings will result.  With respect to a similar
EPA complaint regarding the Registrant's Demopolis, Alabama plant (which was
sold by the Registrant in early 1993), the Registrant settled the matter in
September 1993 by paying a civil penalty of $594,000, approximately one-third
of the penalty originally proposed by the EPA.

In 1993, the State of Michigan alleged that the Registrant's Alpena plant was
managing CKD in violation of applicable state solid waste management
requirements.  The Registrant has formally responded to the State setting forth
defenses and factual information and has had numerous meetings with State
officials to discuss the matters raised, the possible technical solutions and
the possibilities of settlement.  Although significant progress has been made
towards potential settlement, it is unknown at this time whether the Registrant
will be able to settle this matter by agreeing to make certain operational
changes at the plant and/or by paying a penalty amount, or whether an
adjudicatory proceeding will result.

In another matter relating to the Alpena plant and CKD, the State of Michigan
has contacted the Registrant and the former owner of the plant seeking
remediation of an old CKD pile from which there is runoff of hazardous
substances into Lake Huron.  The Registrant has advised the State that it is
not responsible for remediating this property because the property was
expressly excluded in the purchase agreement pursuant to which the Registrant
acquired the plant.  The Registrant has advised the former plant owner of the
Registrant's position on this matter.

In July 1993, the Registrant received a complaint from the EPA alleging certain
RCRA violations at its cement plant in Buffalo, Iowa.  The alleged violations
related to the storage of leaded grease hazardous waste at the plant, and the
EPA proposed a penalty of $284,020.  The Registrant has reached an agreement in
principle with the EPA to settle this matter by paying a penalty of
approximately $40,000.

On or about March 2, 1994 the Registrant was served with a civil investigative
demand by the U.S. Department of Justice, Antitrust Division, requesting the
production of documents and responses to interrogatories in connection with an
investigation of potential price fixing and market allocation by cement
producers.  The Registrant is presently engaged in preparing its responses to
the inquiry.

The Registrant is involved in certain other legal actions and claims.  It is
the opinion of management that all such legal matters will be resolved without
material effect on the Registrant's Consolidated Financial Statements.

Item 5.        MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED
               STOCKHOLDER MATTERS.
 
Information required in response to Item 5 is reported in Item 7, pages II-24
and II-25 of this Annual Report and is incorporated herein by reference.

On March 9, 1994, 58,406,650 Common Shares were outstanding and held by
approximately 2,970 record holders.  In addition, on March 9, 1994, 9,104,150
exchangeable preference shares of LCI, which are exchangeable at the option of
the holder into Common Shares on a one-for-one basis and have rights and
privileges that parallel those of the Common Shares, were outstanding and held
by 7,040 record holders.

The Registrant may obtain funds required for dividend payments, expenses and
interest payments on its debt from its operations in the U.S., dividends from
its subsidiaries or from external sources, including bank or other borrowings.
LCI's loan and credit agreements do not contain restrictions on the payment of
dividends but do contain maximum borrowing restrictions.

Item 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the
consolidated financial statements and notes thereto:


MANAGEMENT'S DISCUSSION OF INCOME

The Consolidated Statements of Income (Item 8, page II-28) summarize the
Registrant's operating performance for the past three years.  To facilitate
analysis, sales and operating profit will be discussed by product line and are
summarized in the table on page II-4 (in millions).  The Registrant's two
product lines are:

   1.    Cement-the production and distribution of portland and specialty
         cements and cementitious materials.

   2.    Construction materials-the production and distribution of ready-mixed
         concrete, construction aggregates, other concrete products, asphalt,
         road construction and the conversion of industrial waste into fuels
         for use in cement kilns.

YEAR ENDED DECEMBER 31, 1993

Net Sales

The Registrant's net sales were $1,494.5 million, down slightly from $1,511.2
million in 1992.  The decrease was due to a drop in the value of the Canadian
dollar relative to the U.S. dollar and sales lost from divested operations
including the Registrant's cement plant in Demopolis, Alabama.  Partially
offsetting these declines were a four percent increase in average cement net
sales prices and higher sales volumes from both cement and construction
materials operations.  Canadian net sales were $640.5 million, a decline of
four percent from last year while U.S.  net sales increased one and one-half
percent to $854.0 million.

The Registrant's net sales from cement operations increased one percent in
1993.  Cement average net sales prices improved four percent over 1992 due to a
six percent increase in the U.S.  Canadian net sales decreased four percent due
to the impact of exchange rates.  In the U.S., net sales increased three
percent.  Prices increased an average of six percent in the Great Lakes U.S.
market and seven percent in the southern U.S.  The Canadian average net sales
price remained stable with lower prices in Ontario offset by higher prices in
the west.

Cement shipments (after adjusting for sales from the Demopolis, Alabama plant,
which was divested in February 1993) increased four percent in 1993 to 12.3
million tons from 11.8 million tons in 1992.  Demand was strongest in U.S.
markets and in western Canada.  U.S. and Canadian shipments increased four
percent and two percent, respectively.  Spot shortages occurred during 1993 in
the southern Great Lakes and Mississippi River markets as the continued
improvement in the U.S. construction market increased the demand for cement.
Additionally, construction activity in the Midwest increased after the flood
waters receded.  Shipments in the Pennsylvania and New England markets
increased over 1992 and prices improved three percent from 1992's depressed
levels.  The Florida market performed well in 1993, with sales volumes up 14
percent from the previous year.  Oilwell cement sales in the western provinces
of Canada nearly doubled in 1993 as an increase in natural gas prices and
changes to the royalty system resulted in an increase in drilling activity.
Additionally, cement shipments in British Columbia increased nine percent over
1992.  In 1993, market conditions in eastern Canada were adversely impacted by
excess cement capacity.  However, the Registrant used surplus capacity in
Ontario to supplement U.S. facilities that were facing inventory shortages.
The Registrant's two cement plants in Ontario increased production and lowered
unit costs although cement demand dropped two percent in the province.
Shipments in the Quebec and Atlantic provinces of Canada were flat in 1993.

<PAGE>   30
Net sales from the Registrant's construction materials and waste management
operations were $802.2 million, down three percent from 1992.  The drop in the
value of the Canadian dollar, sales lost from divested operations in 1992, the
sluggish economy in Canada and flooding in the midwest U.S. were the major
causes of this decline.  In Canada, net sales dropped five percent primarily
due to the decline in the value of the Canadian dollar and the divestment of
the Registrant's chemical admixtures operations in 1992.  Net sales in the U.S.
declined slightly as a result of the weak performance in the Registrant's
northern markets, flooding in the midwest and the divestment of several
construction materials businesses.  These declines were nearly offset by strong
performance in the Registrant's southern U.S. markets.  Registrant-wide,
ready-mixed concrete shipments of 6.1 million cubic yards were one percent
higher than a year ago.  Aggregate sales of 48.1 million tons were four percent
higher than the previous year.  In Canada, ready-mixed concrete shipments
increased two percent due to an increase in construction activity in British
Columbia and Quebec while infrastructure work in eastern Canada boosted
aggregate volumes by eight percent.  In the U.S., ready-mixed concrete and
aggregate volumes declined slightly due to the floods and a drivers strike in
St. Louis coupled with the 1992 sale of several construction materials
businesses.


Gross Profit and Cost of Goods Sold

The Registrant's gross profit as a percentage of net sales improved from 15
percent in 1992 to 17 percent in 1993.  Cement gross profit was 20 percent
compared to 17 percent in 1992 as a result of improved prices.  Over the two
year period, construction materials gross profit was approximately 11 percent.

The Registrant's cement cost per ton is heavily influenced by plant capacity
utilization.  The following table summarizes the Registrant's cement production
(in millions of tons) and the utilization rate of clinker production capacity.
The 1993 figures exclude the Demopolis, Alabama plant which was divested in
February 1993.

Cement production and clinker capacity utilization in 1993 were down somewhat
from a year ago.  In the U.S., cement production totalled 7.2 million tons, an
11 percent decrease from 1992.  Capacity utilization at U.S. plants was 90
percent in 1993 compared to 95 percent in 1992.  The decrease in production and
utilization was due to operating problems at three of the Registrant's cement
plants.  Canadian cement production





                                     II - 6

<PAGE>   31
was 4.1 million tons in 1993, an increase of 11 percent from 3.7 million tons
in 1992.  Capacity utilization was 72 percent and 66 percent in 1993 and 1992.
The increase in production and utilization was primarily due to higher sales
volumes and the use of surplus capacity in the Registrant's Ontario plants to
supplement U.S. markets that were experiencing cement shortages.


Selling and Administrative

Selling and administrative expenses were $161.4 million in 1993, $23.3 million
(13 percent) lower than 1992.  This reduction resulted primarily from
divestments and actions taken to streamline operations and reduce costs in the
Registrant's cement and construction materials operations over the last two
years.  Selling and administrative expenses as a percentage of net sales
declined to 10.8 percent in 1993 from 12.2 percent in 1992.


Other (Income) Expense, Net

Other income and expense consists of items such as net retirement costs, equity
income, amortization of intangibles and nonrecurring gains and losses from
divestitures.  Other income, net was $1.0 million in 1993 compared to expense
of $9.1 million in 1992.  The change was the result of higher divestment gains
from the sale of non-strategic assets and lower amortization coupled with the
absence of strike related costs at the Richmond plant.


Restructuring

In the fourth quarter of 1993, the Registrant recorded a one-time pre-tax
restructuring charge of $21.6 million ($16.4 million net of tax benefits) to
cover the direct expenses of restructuring the Registrant's North American
business units to increase organizational efficiency.  The primary components
of the restructuring charge are separation benefits for approximately 350
employees ($15.2 million), and employee relocation ($3.3 million).  The charge
also includes expenses such as office relocation and lease termination.  No
amounts were paid relative to these items in 1993.

The restructuring plan entails the consolidation of 11 regional operating units
into six units in the Registrant's two main business lines.  This consolidation
reduces management layers, eliminates duplicative administrative functions and
standardizes procedures and information systems.  Manufacturing and
distribution facilities will not be materially affected by the restructuring.
The Registrant expects the annual expense reductions from the restructuring to
be approximately $8 million after-tax in 1994 and increasing to approximately
$19 million after-tax once the restructuring is fully implemented.

Performance by Line of Business

In 1993, the Registrant's operating profit from cement operations (before
corporate and unallocated expenses) was $96.4 million, $29.8 million better
than 1992.  All regions reported better results than the prior year.  Cement
results were much better due to higher prices and stronger shipments,
particularly in the second half of 1993.  The most notable progress was in the
U.S. markets.  Prices were up six percent in the U.S.  but unchanged in Canada.
The Registrant's Canadian operations reported an operating profit of $46.2
million, $5.5 million better than last year.  Earnings increased in western
Canada due to higher shipments and the absence of costs related to the strike
at the Richmond plant that was settled in March 1992.  Earnings declined in
central Canada due to the continued sluggish market but improved in eastern
Canada primarily due to higher intraregional sales to the U.S. New England
markets.  Earnings from U.S. cement operations were $50.2 million, or $24.3
million better than 1992.  Results improved in all U.S. regions, mainly due to
the six percent increase in average net selling prices combined with a four
percent increase in shipments.

The operating profit from the Registrant's construction materials and waste
management operations in 1993 (before corporate and unallocated expenses) was
$30.6 million, $20.9 million better than 1992.  Earnings were boosted by cost
reductions and higher ready-mixed concrete and block prices in central Canada,
improved ready-mixed concrete and aggregate volumes in eastern Canada,
partially offset by lower ready-mixed concrete prices in the western provinces
due to competitive pressures in a number of markets.  The Canadian operations
contributed $20.3 million, $14.7 million higher than the prior year.  Most of
the increase was attributable to the Registrant's Ontario-based concrete
products operations.  The U.S. operating profit totalled $10.3 million, $6.2
million better than 1992.  This improvement was primarily attributable to the
Registrant's construction materials operations in the southern U.S. resulting
from higher ready-mixed concrete volumes, lower stone costs and a $3.1 million
write-down of a quarry last year.  Partially offsetting these gains were an
earnings decline in the Registrant's northern U.S. markets due to the continued
poor economic climate and high operating costs in the midwest markets as a
result of the summer floods and a drivers strike.


Total Income From Operations

Total income from operations was $70.2 million in 1993, an increase of $42.2
million from 1992.  The improved performance was due largely to a six percent
increase in the U.S. average cement net sales price.  Also contributing to the
results were an $18.2 million turnaround in profitability of the Registrant's
construction materials operations in central and eastern Canada, higher
shipments in the western cement region, higher divestment gains from the sale
of non-strategic assets and a 13 percent reduction in selling and
administrative expenses.  These improvements were partially offset by a
one-time restructuring





                                     II - 8

<PAGE>   33
charge of $21.6 million.  The Registrant's operating profit from its Canadian
operations was $36.7 million, $3.2 million better than 1992.  Operating profit
from U.S. operations was $33.5 million, $39.0 million better than 1992.


Interest Expense, Net

Net interest expense decreased by $6.7 million in 1993 due to lower average
debt levels.


Income Taxes

Income tax expense increased $5.9 million in 1993.  U.S. taxes increased $3.0
million primarily due to a $2.6 million increase in deferred income taxes.  The
Canadian income taxes increased $2.9 million due to higher earnings in Canada.
The Canadian effective income tax rates were 46.1 percent in 1993 and 42.7
percent in 1992.  Certain elements of the Canadian income tax provision are
fixed in amount.  The increase in the Canadian effective tax rate in 1993 was
caused by the relatively higher percentage of these fixed amounts to the higher
earnings experienced in 1993, partially offset by a tax rate reduction enacted
during 1993.


Net Income

In 1993, the Registrant reported net income of $5.9 million.  This was $106.5
million better than 1992's net loss of $100.6 million.  The 1992 loss included
$12.1 million after-tax of employee severance and other nonrecurring charges,
while 1993 results included an after-tax charge of $16.4 million related to
corporate restructuring recorded in the fourth quarter.  The 1992 loss also
included $63.5 million in after-tax charges related to the adoption of new
accounting rules for postretirement benefits and income taxes.  Excluding this
one-time charge, net income in 1993 was $43.0 million better than 1992.

Excluding one-time charges resulting from the adoption of these new accounting
rules, the Registrant's Canadian operations reported net income of $20.5
million, $0.8 million higher than 1992.  The increase was due to better results
in the Registrant's ready-mixed concrete and aggregate operations in central
and eastern Canada, higher shipments in the western cement region and the
absence of strike related costs at the Richmond plant.  These increases were
offset by a four percent decline in net sales and lower divestment gains.

After excluding one-time charges resulting from the adoption of new accounting
rules, the Registrant's U.S. operations incurred a net loss of $14.6 million.
This was $42.2 million better than 1992.  The improved U.S. performance was the
result of a $4.9 million gain realized from the expropriation of property at
one of the Registrant's construction materials operations and an increase in
cement volumes and





                                     II - 9

<PAGE>   34
prices.  In addition, interest expense in the U.S. was $6.2 million lower than
the previous year.  U.S. results were negatively impacted by infrequently
occurring maintenance projects (those required every three years or more) and
an earnings decline in the Registrant's northern and midwest construction
materials markets.


Recent Acquisitions

On January 16, 1991, the Registrant acquired Missouri Portland/ Davenport which
was engaged in the production and distribution of cement and construction
materials.  The three cement plants acquired increased the Registrant's annual
clinker production capacity by 25 percent and created significant production
and distribution synergies with the Registrant's existing operations,
especially along the Mississippi River.

The acquisition included 30 ready-mix operations, two aggregate quarries as
well as the assets of a chemical admixtures business which was divested in
1992.


General Outlook

The Registrant's general outlook for 1994 in the Cement Group is favorable,
particularly in the United States.  According to the Dodge/Sweet's Outlook '94,
total new construction in the U.S. is projected to increase six percent in real
terms in 1994.  This would be the third consecutive year of improvement.
Cement consumption generally correlates with trends in construction
expenditures.  In Canada, cement consumption is expected to be boosted by the
housing sector and Ottawa's Cdn. $6 billion public works program.
Additionally, in early 1994, the Registrant was chosen to supply 160,000 metric
tons of silica fume cement over three years starting in 1994 for the
construction of the Prince Edward Island eight-mile bridge in Canada's Atlantic
provinces.  The Portland Cement Association ("PCA") forecasts higher cement
consumption in all provinces.

The upward trend in prices during 1993 and the higher cement consumption
forecasted by the PCA provides some optimism about the 1994 climate for cement
prices.  Price increases were phased in at various times during 1993;
therefore, their full impact will not be realized until 1994.  Also, the
Registrant has announced increases for the first part of 1994 in most North
American markets.

The Registrant's expectations for the construction materials group hold promise
for 1994.  In Canada, the gradual recovery of construction activity should
allow room for a modest increase in construction materials volumes, although
performance will once again vary by region.  In the Maritimes, the Registrant
has a contract to furnish approximately 370,000 cubic meters of concrete over a
three year period for the bridge to Prince Edward Island.  In the U.S., the
group's major business line,





                                    II - 10

<PAGE>   35
aggregates, is likely to experience a decline in volumes due to recent
divestments; however, average margins are expected to improve.  The
Registrant's U.S. ready-mixed concrete deliveries should improve as the
economic recovery continues to gain momentum.

YEAR ENDED DECEMBER 31, 1992

Net Sales

Net sales in 1992 decreased four percent to $1,511.2 million from $1,568.8
million in 1991 due to sluggish construction activity in central and eastern
Canada and a drop in the value of the Canadian dollar relative to the U.S.
dollar.

The Registrant's net sales from cement operations declined two percent in 1992
due mainly to a five percent decline in the average value of the Canadian
dollar.  The average net sales price declined slightly from 1991 due to lower
prices in the U.S.  In the Great Lakes and Northeastern Regions, competitive
pressures caused prices to fall, offsetting price gains in the west.  Cement
shipments were up two percent from 1991 due to improvements in the U.S. Great
Lakes.  In Canada, higher shipments in the west were offset by decreases in
eastern and central Canada due to sluggish construction activity.

Net sales from the Registrant's construction materials and waste management
operations were 12 percent less than 1991 in Canada but nine percent more in
the U.S., resulting in an overall decline of five percent.  Compared to 1991,
ready-mixed concrete and aggregate volumes in Canada were nine and six percent
lower due to the continued weakness in the Toronto and Montreal markets.
Ready-mixed concrete and aggregate volumes in the U.S. were six percent and 11
percent higher.  The U.S. improvement was primarily the result of a greater
market penetration in the northern U.S. and an improving market in Texas.


Gross Profit and Cost of Goods Sold

The Registrant's gross profit as a percentage of net sales was 14.7 percent in
1992, slightly better than 14.3 percent in 1991.  Cement gross profit as a
percentage of net sales was 17.4 percent in 1992 and 16.6 percent in 1991.
Over the two-year period, construction materials gross profit as a percentage
of net sales was approximately 10 percent.

The Registrant's cement unit cost is heavily influenced by plant capacity
utilization.  The following table summarizes the Registrant's cement production
(in millions of tons) and the utilization rate of clinker production capacity.

<PAGE>   37
Cement production increased one and one-half percent in 1992 while clinker
capacity utilization was 83 percent, down from 85 percent in 1991.  In the
U.S., cement production totalled 8.1 million tons, an increase of four percent
over 1991.  Capacity utilization at U.S. plants was 95 percent in 1992 compared
to 94 percent in 1991.  The increase in production and utilization was
primarily due to higher sales volumes.  Canadian cement production fell to 3.7
million tons in 1992, a decline of three percent from 1991.  Capacity
utilization was 66 percent and 71 percent in 1992 and 1991, respectively.  The
decline resulted from the temporary shutdown of certain kilns at three of the
Registrant's plants in Canada due to a decrease in cement demand.


Selling and Administrative

Selling and administrative expenses decreased seven percent in 1992 primarily
due to the 1991 restructuring of the Registrant's cement operations following
the Missouri Portland/Davenport acquisition in January 1991 and other
restructuring in the Registrant's construction materials operations,
particularly in Ontario.  These savings were partially offset by 1992
provisions for additional restructuring.

Selling and administrative expenses as a percentage of net sales were 12.2
percent in 1992, down from 12.7 percent in 1991.


Other (Income) Expense, Net

Other income and expense consists of items such as net retirement costs, equity
income, amortization of intangibles and nonrecurring gains and losses from
divestitures.  Other expense, net was $9.1 million in 1992 compared to $8.1
million in 1991.  The change was the result of recurring expenses from adopting
the new accounting rule for postretirement benefits as well as nonrecurring
provisions for contingencies and restructuring.  These charges were partially
offset by lower retirement costs, higher equity income and divestment gains
from the sale of non- strategic assets and lower costs related to the strike at
the Richmond plant.


Performance by Line of Business

The Registrant's operating profit from cement operations in 1992 was $66.6
million, $14.7 million better than 1991.  Earnings improved in three of the
Registrant's four cement regions.  Depreciation expense increased by $3.4
million as a result of the new accounting rule for income taxes.  The Canadian
operating profit was $40.8 million, $7.5 million better than 1991.  Profits in
western Canada improved due to the end of a strike at the Richmond plant plus
higher shipments and prices.  Profits declined in central and eastern Canada
due to sluggish construction activity.  In the U.S., operating profit was $25.8
million, up $7.2 million from 1991.  Earnings improved in all markets except
the Northeast.





                                    II - 13

<PAGE>   38
In 1992, operating profit from the Registrant's construction materials and
waste management operations was $9.7 million, $4.6 million lower than 1991.
Earnings declined because of lower shipments in central and eastern Canada.
Canadian operating profit was $5.6 million, $11.6 million less than 1991.  Weak
construction activity in central and eastern Canada was primarily responsible
for the decline.  Profit was higher in western Canada as a result of higher
shipments.  In the U.S., operating profit in 1992 was $4.1 million, or $7.0
million better than the previous year.  The improvement resulted from better
market conditions and higher prices in the South coupled with a reduction of
overhead expenses in the Midwest.


Total Income From Operations

Total income from operations improved in 1992 to $28.0 million from $17.7
million in 1991, after recording as an additional expense the $9.4 million
recurring impact of accounting changes.  A majority of the improvement came
from restructuring and cost-reduction programs as well as divestment gains.
Earnings were boosted by $9.6 million of gains from the sale of non-strategic
assets.  Operating profit from the Registrant's Canadian operations before the
impact of accounting changes was $34.4 million, $7.6 million better than 1991.
The U.S. operating profit before accounting changes was $3.0 million, $12.1
million better than 1991.


Interest Expense, Net

In 1992, net interest expense decreased five percent due to lower interest
rates and lower average debt levels in both the U.S. and Canada.


Income Taxes

Income tax expense decreased $0.4 million in 1992.  The Canadian effective
income tax rates were 42.7 percent in 1992 and 56.0 percent in 1991.  Certain
elements of the Canadian income tax provision which are fixed in amount were
higher in 1991 but lower in 1992.  The decrease in the Canadian effective tax
rate in 1992 was caused by a lower percentage of these fixed amounts relative
to the higher earnings experienced in 1992.


Net Loss

The Registrant's net loss in 1992, excluding charges resulting from the
adoption of the new accounting rules, was $28.1 million.  This was a 44 percent
improvement over the 1991 net loss of $50.3 million.  The Registrant's Canadian
operations reported net income of $20.3 million, an $8.1 million increase over
1991.  Canadian earnings benefitted from





                                    II - 14

<PAGE>   39
$4.1 million of gains (net of tax), realized primarily from the sale of surplus
land and a chemical admixtures business.  In addition, expenses were reduced
from actions taken in 1991 and during 1992 to streamline operations and reduce
cost, and a reallocation of corporate overhead from the U.S. to Canada.
Offsetting these gains were a nine percent decline in Canadian net sales due to
weak shipments in eastern and central Canada, nonrecurring provisions for
contingencies and restructuring, and a decrease in the value of the Canadian
dollar.  In the U.S., the net loss before accounting changes was $48.4 million,
which was $14.1 million better than 1991.  The U.S. improvement was primarily
due to restructuring and cost reduction programs as well as better market
conditions and higher prices in the Registrant's southern construction
materials operations offset by reallocation of corporate overhead from Canada.


ENVIRONMENTAL MATTERS

The Registrant's operations, like those of other companies engaged in similar
businesses, involve the use, release/discharge, disposal and clean-up of
substances regulated under increasingly stringent federal, state, provincial
and/or local environmental protection laws.  Many of the regulations are
technically and legally complex, posing significant compliance challenges.  The
Registrant's environmental compliance program includes an environmental policy
designed to provide corporate direction for all operations and employees,
routine compliance oversight of the Registrant's facilities, routine training
and exchange of information by its environmental professionals, and routine and
emergency reporting systems.

The Registrant has been, or is presently involved in certain environmental
enforcement matters, in both the U.S. and Canada.  Management's philosophy is
to attempt to actively resolve such matters with the appropriate governmental
authorities.  In certain circumstances, notwithstanding management's belief
that a particular alleged violation poses no significant threat to the
environment, the Registrant may decide to resolve such matter by entering into
a consent agreement and/or paying a penalty.

In 1992, the Registrant's four cement plants using hazardous waste derived
fuels submitted certifications of compliance for the emission limits
established under the federal Resource Conservation and Recovery Act ("RCRA"),
Boiler and Industrial Furnaces ("BIF") regulations.  The BIF regulations also
require extensive record keeping of operational parameters and of fuels and raw
materials used.  The BIF regulations are extremely complex and certain
provisions have been subject to different interpretations.  The Registrant has
received a notice of violation and/or a complaint alleging violations of the
BIF regulations at each of four cement plants.  These notices of violation and
complaints were issued by the U.S. Environmental Protection Agency ("EPA") with
respect to three plants and by the State of Michigan, which has been delegated
BIF enforcement authority by the EPA, with respect to a fourth plant.





                                    II - 15

<PAGE>   40
Although the details of each notice of violation or complaint are specific to
the particular plant, a recurring issue has been the existence or adequacy of
the plant's waste analysis plan to ensure compliance with the established
allowable emission limits and feed rates.  All of the Registrant's plants which
are subject to the BIF regulations have revised their waste analysis plans and
submitted them for approval.  Furthermore, to reduce the potential recurrence
of BIF violations, the Registrant has designated an employee who is responsible
for managing the Registrant's BIF compliance, including routine auditing of
plant operations and plant records which are required to document compliance
with the BIF regulations.  The current status of these BIF-related matters is
as follows:  With respect to the Demopolis, Alabama plant (which was sold by
the Registrant in early 1993), the Registrant settled the matter by paying a
penalty of $594,000, approximately one-third of the penalty originally proposed
by the EPA.  The State of Michigan has proposed a penalty of $979,750 with
respect to the Alpena, Michigan plant and the EPA has proposed penalties of
$619,800 with respect to the Paulding, Ohio plant and $1,200,474 with respect
to the Fredonia, Kansas plant.  The Registrant has submitted a response to each
notice of violation and complaint setting forth certain defenses and factual
information and has had meetings with the EPA and Michigan State officials to
discuss the alleged violations and the possibilities of settlement.  At this
time, it is unknown whether the Registrant will be able to settle any or all of
these matters or whether one or more adjudicatory proceedings will result.

In late February 1994, a decision was issued in a lawsuit challenging certain
aspects of the BIF regulations.  The court's decision, among other things,
vacated the tier III standard for hydrocarbon emission levels and instructed
the EPA to reconsider the tier III standard.  Two of the Registrant's plants
have been complying with the tier III standard and are currently not able to
meet either the tier I standard or the tier II standard, which are the two
remaining standards.  The Registrant is evaluating potential raw material
alternatives and technological modifications at these two plants to determine
whether one or both of the plants could meet the tier I standard or the tier II
standard.  The Registrant is also working with the EPA to have an interim
replacement standard put in place pending the EPA's reconsideration of the tier
III standard.  In the absence of the tier III standard or a substantially
similar replacement standard, the Registrant might have to stop using
supplemental fuels at one or both of these plants.

A by-product of many of the Registrant's cement manufacturing plants is cement
kiln dust ("CKD").  CKD has been excluded from regulation as a hazardous waste
under the so-called "Bevill Amendment" to RCRA until the EPA completes a study
of CKD, determines if it is hazardous waste, and issues appropriate rules.  On
December 30, 1993, the EPA issued its Report to Congress and proposed five
regulatory options for CKD.  The EPA has solicited public comments on the
Report to Congress and the regulatory options, following which it will make a
final regulatory









                                    II - 16

<PAGE>   41

 
determination of how, if at all, CKD should be regulated in the future.
The Registrant is actively participating in this opportunity to submit comments
and offer constructive regulatory alternatives.  One of the regulatory
alternatives being considered by the EPA would classify as a hazardous waste
the CKD which is produced by facilities burning hazardous waste as a
supplemental fuel.  The Registrant's management does not believe that the data
included in the Report to Congress support such an approach.  If, however, this
option is selected by the EPA, the Registrant could incur significant capital
costs to meet these new standards, might have to stop using supplemental fuels
at its plants, and/or might close one or more plants.

In 1993, the State of Michigan alleged that the Registrant's Alpena plant was
managing CKD in violation of applicable state solid waste management
requirements.  The Registrant has formally responded to the State setting forth
defenses and factual information and has had numerous meetings with State
officials to discuss the matters raised, the possible technical solutions and
the possibilities of settlement.  Although significant progress has been made
towards potential settlement, it is unknown at this time whether the Registrant
will be able to settle this matter by agreeing to make certain operational
changes at the plant and/or by paying a penalty, or whether an adjudicatory
proceeding will result.

In another matter relating to the Alpena plant and CKD, the State of Michigan
has contacted the Registrant and the former owner of the plant seeking
remediation of an old CKD pile from which there is runoff of hazardous
substances into Lake Huron.  The Registrant has advised the State that it is
not responsible for remediating this property because the property was
expressly excluded in the purchase agreement pursuant to which the Registrant
acquired the plant.  The Registrant has advised the former plant owner of the
Registrant's position on this matter.

In view of the current uncertainty regarding the future regulatory treatment of
CKD and with the goal of minimizing long-term liability exposure, the
Registrant has been assessing its management practices for CKD in the U.S. and
Canada and is voluntarily taking remedial steps and instituting new management
practices as well as assessing and modifying process operations, evaluating and
using alternative raw materials and implementing new technologies for reducing
the generation of CKD.

As with most industrial companies in the U.S., the Registrant is involved in
certain remedial actions to clean up historical problem waste disposal sites as
required by federal and state laws, which provide that responsible parties must
fund remedial actions regardless of fault or legality at the time of the
original disposal.  In this regard, the Registrant is presently involved in
approximately 15 federal and state administrative proceedings.  At all but four
of these sites, the Registrant is either a de minimis party or the Registrant
has information to support its position that it did not contribute/dispose, or
is not legally responsible for the disposal of materials at the site.  With
respect to two of the four sites, the Registrant has entered into 






                                    II - 17

<PAGE>   42
consent agreements with the applicable governmental authorities and
received approval in late 1993 to proceed with its proposed remediation plans.
In these two cases, the Registrant has recorded provisions for exposure, but
has sought to obtain contributions from other non-settling parties and/or
believes that its liability insurance covers these costs and is pursuing
recovery from its insurers.  At a third site, the Registrant has undertaken
remediation under a state order of property which the Registrant had leased to
an automobile workshop that had a leaking underground storage tank.  The lessee
vacated the property and did not have the financial resources to clean up the
site.  The Registrant has completed remediation of the site and is awaiting
state approval.  The fourth site is the old CKD pile at the Alpena plant
discussed above.

The 1990 Clean Air Act Amendments have the potential to result in significant
capital expenditures and operational expenses for the Registrant.  The Clean
Air Act Amendments established a new federal operating permit and fee program
for virtually all manufacturing operations.  By 1995, the Registrant's U.S.
operations that are deemed to be "major sources" of air pollution will have to
submit detailed permit applications and pay recurring permit fees.  To ensure
the timely submittal and completeness of permit applications for the
Registrant's "major sources", the Registrant has designated an employee to
manage the identification of "major sources", prepare permit applications, and
negotiate permit terms with the appropriate state agencies.  The EPA is also
developing air toxics regulations for a broad spectrum of industrial sectors
including portland cement manufacturing.  The EPA has indicated that the new
maximum available control technology ("MACT") standards could force a
significant reduction of air pollutants below existing levels.  The Registrant
is actively participating with other cement manufacturers in working with the
EPA to define test protocols, better define the scope of MACT standards and
develop realistic emission limitations for the portland cement industry.  Until
the EPA better defines the applicability and scope, and the proposed emission
standards, management cannot determine whether technology in fact exists today
to meet such standards and, if it does, the facilities which will be required
to install additional controls and the associated costs for such controls.

The Registrant's ready-mixed concrete operations generate a cement sludge from
concrete recycling.  Governmental authorities, especially in Canada, are
beginning to focus on regulating management of this residual waste.  The
Registrant has been voluntarily assessing its cement sludge management
practices in the U.S. and Canada.  The Registrant hopes to identify new
technologies, process modifications and alternative raw materials/additives
with the goal of reducing the generation of cement sludge and/or establishing
alternative management practices.

Because of differences between requirements in the U.S. and Canada, and the
complexity and uncertainty of existing and future environmental requirements,
permit conditions, costs of new and existing technology, potential remedial
costs and insurance coverage, and/or enforcement 






                                    II - 18

<PAGE>   43
related activities and costs, it is difficult for management to estimate
the ultimate level of the Registrant's expenditures related to environmental
matters.  The Registrant's capital expenditures and operational expenses for
environmental matters have increased, and are likely to increase in the future.
The Registrant, however, cannot determine at this time if capital expenditures
and other remedial actions that the Registrant has taken, or may in the future
be required to undertake, in order to comply with the laws governing
environmental protection will have a material effect upon its capital
expenditures or earnings.

MANAGEMENT'S DISCUSSION OF CASH FLOWS

The Consolidated Statements of Cash Flows summarize the Registrant's main
sources and uses of cash.  These statements show the relationship between
operations which are presented in the Consolidated Statements of Income and
liquidity and financial resources which are depicted in the Consolidated
Balance Sheets.

The Registrant's liquidity requirements arise primarily from the funding of its
capital expenditures, working capital needs, debt service obligations and
dividends.  The Registrant has met its operating liquidity needs primarily
through internal generation of cash and expects to continue to do so for both
the short-term and long-term.  However, because of the seasonality of the
Registrant's business, it must borrow to fund operating activities during the
spring and summer.

The net cash provided by operations for each of the three years presented
reflects the Registrant's net income (loss) adjusted primarily for
depreciation, depletion and amortization, changes in working capital,
restructuring charges in 1993, and the cumulative effect of accounting changes
in 1992.  Depreciation and depletion increased in 1992 from 1991 because of
capital expenditures and acquisitions but declined in 1993 due to lower capital
spending and divestments.  In addition, net income (loss) was adjusted by the
provision for bad debts.  This provision has declined over the three year
period due to tighter credit policies and a healthier construction market in
1993.  During all three years presented, net income (loss) was also adjusted
for the turnaround of deferred income taxes, primarily from reversing
depreciation differences in Canada, and changes in working capital, which is
discussed in Management's Discussion of Financial Position.  Finally, net
income (loss) from operations was adjusted for gains on sales of assets and
other noncash charges and credits.  These charges and credits consist
principally of equity income net of dividends received, other postretirement
benefit accruals, increases in prepaid pension assets and minority interests.

Cash flows invested consist primarily of capital expenditures and acquisitions
partially offset by proceeds on property, plant and equipment dispositions.
Sales of property, plant and equipment during 1993 and 1992 included
significant divestments of non-strategic assets.  During 1993 the Registrant's
proceeds from the sale of non-strategic assets and surplus land totalled
approximately $68.9 million.  In 1992 the proceeds from divestment of several
construction materials businesses and surplus land totalled $25.1 million.
Capital investments, including acquisitions, by product line were as follows
(in millions):

</TABLE>

Capital investments related to existing operations are not expected to exceed
$130 million in 1994.  This capital spending is anticipated to be funded by
cash flows from operations, after dividends, and proceeds from divestments.

During 1993, the Registrant continued its program to regain financial
flexibility by reducing its debt position.  Debt was reduced by cash flows from
operations, divestments and proceeds from the sale of Common Shares.  Net cash
outflows from financing activities were $124.4 million in 1993 and $14.9
million in 1992.  In 1991, cash flows from financing activities were $26.3
million, reflecting borrowings required to finance a portion of the
Registrant's capital investments.

In February 1993, the Registrant sold its Demopolis, Alabama cement facility
and other related assets for approximately $50 million cash.  In early 1992,
the Registrant sold 1.7 million Exchangeable Shares of LCI, a wholly owned
subsidiary, that it had accumulated through exchange transactions for net
proceeds of $25.8 million.  In October 1993 the Registrant completed an
offering of 6.75 million Common Shares priced at $18.25 per share.  The net
proceeds from the offering, which were used initially to reduce long-term debt,
totalled $117.6 million.  The Registrant intends to apply the proceeds to
internal capital improvement projects and investment or acquisition
opportunities to enhance or expand the Registrant's competitive position in the
U.S. and Canada.

The Registrant has access to a wide variety of short-term and long-term
financing alternatives in both the U.S. and Canada.  Effective December 15,
1993, the Registrant extended the maturity of its $200 million committed credit
facility to December 31, 1996.  Although none of the credit facility had been
drawn down at December 31, 1993, approximately $11 million was utilized to back
outstanding short-term bank loans.

Most of the Registrant's cash and cash equivalents are in Canada.  If the cash
were transferred to the U.S., a 10 percent withholding tax would be levied in
Canada which, because of the Registrant's U.S. net operating loss position,
would not provide an offsetting tax credit in the U.S.

MANAGEMENT'S DISCUSSION OF FINANCIAL POSITION

The Consolidated Balance Sheets summarize the Registrant's financial position
at December 31, 1993 and 1992.

The value reported for Canadian dollar denominated net assets decreased from
December 31, 1992 as a result of a drop in the value of the Canadian dollar
relative to the U.S. dollar.  At December 31, 1993 the U.S. dollar equivalent
of a Canadian dollar was $ .76 versus $ .79 at December 31, 1992.

Working capital, excluding cash and current portion of long-term debt,
decreased $6.5 million as a result of the drop in the value of the Canadian
dollar relative to the U.S. dollar.  The impact of these exchange rate changes
was to reduce accounts receivable by $5.8 million, inventories by $4.0 million,
and accounts payable by $2.7 million.

Working capital, excluding cash, current portion of long-term debt and the
impact of exchange rate changes, decreased $49.2 million from December 31, 1992
to December 31, 1993.  Accounts receivable increased $14.3 million during the
year primarily due to a five percent increase in net sales in the fourth
quarter of 1993 compared to 1992.  (Net sales are detailed in Management's
Discussion of Income).  Inventories decreased $36.1 million mainly due to a
seven percent increase in cement shipments in the fourth quarter resulting from
the continued improvement in the construction market coupled with milder
weather conditions in most of the Registrant's major markets.  Also
contributing to the decline in inventories was the impact of divestments.  The
increase in other current assets was due to higher deferred income tax assets.
Accounts payable and accrued liabilities increased $38.8 million, mainly due to
the $21.6 million restructuring accrual and the timing of purchases and
payments.

Net property, plant and equipment decreased $101.6 million during 1993.  The
impact of exchange rates resulted in $16.0 million of this decrease.
Depreciation and divestments were $108.5 million and $51.9 million.  Capital
expenditures and acquisitions totalled $67.2 million.

The excess of cost over net assets of businesses acquired related primarily to
a 1981 U.S. acquisition.  During 1993, this balance decreased primarily due to
current year amortization.  Other long-term liabilities increased $13.9 million
during 1992.  The increase was due to higher minority interests of $12.4
million primarily resulting from a construction materials joint venture in
Canada ($7.2 million) and proceeds from the expropriation of property in a U.S.
construction materials joint venture ($4.7 million).  The adoption of SFAS No.
106, "Employers Accounting for Postretirement Benefits Other than Pensions",
was recorded effective January 1, 1992 and resulted in the establishment of a
$111.0 million liability.  The related 1993 and 1992 accruals, net of actual
payments, were $4.5 million and $6.0 million, respectively.  The new accounting
standard requires that the expected cost of retiree health care and life
insurance benefits be charged to expense during the

years that the employees render service rather than the Registrant's past
practice of recognizing these costs on a cash basis.

The Registrant's capitalization is summarized in the following table:

MANAGEMENT'S DISCUSSION OF SHAREHOLDERS' EQUITY

The Consolidated Statements of Shareholders' Equity summarize the
activity in each of the components of shareholders' equity for the three years
presented. Shareholder's equity increased $91.7 million in 1993.  The increase
was mainly due to the October 1993 sale of 6.75 million shares of Common Shares
for net proceeds of $117.6 million.  Also positively impacting 1993
shareholders' equity was net income of $5.9 million.  Partially offsetting
these increases were dividend payments, net of reinvestments of $14.3 million,
and a change in the foreign currency translation adjustments of $24.6 million
resulting from a decline in the value of the Canadian dollar relative to the
U.S. dollar.

Shareholders' equity decreased $142.0 million in 1992 due to the net loss of
$100.6 million, a change in the foreign currency translation adjustments of
$62.8 million resulting from a significant decline in the value of the Canadian
dollar relative to the U.S. dollar and dividend payments, net of reinvestments,
totalling $7.7 million.  Offsetting these declines were the sale of 1.7 million
Exchangeable Shares of LCI in February 1992 for net proceeds of $25.8 million.

Common equity interests include Common Shares and the LCI Exchangeable Shares,
which have comparable voting, dividend and liquidation rights.  Common Shares
are traded on the New York Stock Exchange under the ticker symbol "LAF" and on
The Toronto Stock Exchange and the Montreal Exchange.  The Exchangeable Shares
are traded on the Montreal Exchange and The Toronto Stock Exchange.

MANAGEMENT'S DISCUSSION OF SELECTED FINANCIAL DATA

The Selected Consolidated Financial Data provides both a handy reference for
some data frequently requested about the Registrant and a useful record in
reviewing trends.

The Selected Consolidated Financial Data for 1990 and 1989 has been restated
from January 1, 1989 to reflect the Missouri Portland/Davenport acquisition.

The Registrant's net sales increased six percent from 1989 to 1990 because of
acquisitions and, to a lesser extent, increased business activity in the
Registrant's markets.  The 11 percent decline in the Registrant's net sales
from 1990 to 1991 reflects the lower sales volumes during the recession,
whereas the four percent decline from 1991 to 1992 was caused by sluggish
construction activity in central and eastern Canada coupled with a decline in
the average value of the Canadian dollar.  The one percent decline from 1992 to
1993 was due to the drop in the value of the Canadian dollar and lost sales
from divested operations,  partially offset by a four percent increase in
average cement net sales prices and higher cement and construction materials
sales volumes as discussed in Management's Discussion of Income.

Inflation has not been a significant factor in the Registrant's sales or
earnings growth due to lower inflation rates in recent years, and because the
Registrant continually attempts to offset the effect of inflation by improving
operating efficiencies, especially in the areas of selling and administrative
expenses, productivity and energy costs.  The ability to recover increasing
costs by obtaining higher prices for the Registrant's products varies with the
level of activity in the construction industry and the availability of products
to supply a local market.

During 1989 and 1990, the Registrant's cement selling price increases in the
U.S. and in Canada were generally less than the rate of inflation.  In 1991,
that pattern continued in the U.S.; however, Canadian selling prices were
relatively stable in 1991.  In 1992, selling prices in the U.S. decreased 1.4
percent while Canadian selling prices increased one percent.  In 1993 selling
prices in the U.S. increased six percent while average Canadian prices were
unchanged despite depressed volumes and competitive pressures in Ontario.

Net cash provided by operations consists primarily of net income (loss),
adjusted primarily for depreciation, restructuring charges in 1993 and, in
1992, the cumulative effect of changes in accounting principles.  The
Registrant is in a capital intensive industry and as a result recognizes large
amounts of depreciation.  The Registrant has used the cash provided by
operations primarily to expand its markets and to improve the performance of
its plants and other operating equipment.

Capital expenditures and acquisitions totalled $771.1 million over the five
years and included the acquisition of The Standard Slag Company (Part of the
U.S. Region) which has a network of aggregates and construction materials
businesses located in the U.S. Great Lakes area.  Other significant investments
during the period included a variety of cement plant projects to increase
production capacity and reduce costs, the installation of waste fuel receiving
and handling facilities, the building of additional distribution terminals to
extend markets and improve existing supply networks, acquisitions of
ready-mixed concrete plants and aggregate operations, and modernization of the
construction materials mobile equipment fleet.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Together with its subsidiaries, Lafarge Corporation (the "Registrant"), a
Maryland corporation, is engaged in the production and  sale of cement,
ready-mix concrete, aggregates and other concrete products.  The Registrant
operates in the U.S. and its major operating subsidiary, LCI, operates in
Canada. The Registrant's wholly-owned subsidiary, Systech Environmental
Corporation, and its Canadian affiliate (together "Systech"), are involved in
the conversion of waste into fuels for use in cement kilns. Lafarge Coppee
S.A., a French corporation, and certain of its affiliates ("Lafarge Coppee")
own a majority of the voting securities of the Registrant.


ACCOUNTING AND FINANCIAL REPORTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of the Registrant
and all of its majority-owned subsidiaries (the "Registrant"), after the
elimination of intercompany transactions and balances. Investments in
affiliates in which the Registrant has less than a majority ownership are
accounted for by the equity method.

Foreign Currency Translation

Assets and liabilities of LCI are translated at the exchange rate prevailing at
the balance sheet date. Revenue and expense accounts for this subsidiary are
translated using the average exchange rate during the period. Foreign currency
translation adjustments are disclosed as a separate item in shareholders'
equity.

Revenue Recognition

Revenue from the sale of cement, concrete products and aggregates is recorded
at the time the products are shipped. Revenue from waste recovery and disposal
is recorded at the time the material is received, tested and accepted.  Revenue
from road construction contracts is recognized on the basis of units of work
completed, while revenue from other indivisible lump sum contracts is
recognized using the percentage-of-completion method.

Change in Accounting Principles

Effective January 1, 1992 the Registrant adopted Statements of Financial
Accounting Standards ("SFAS") No. 106, "Employers' Accounting for
Postretirement Benefits Other than Pensions," and No. 109, "Accounting for
Income Taxes."  The cumulative effect of these changes in accounting principles
of $63.5 million (after-tax) was recorded as a charge to expense in 1992.





                                    II - 32

<PAGE>   57
                         Other Postretirement Benefits

SFAS No. 106 requires that the expected cost of retiree health care and life
insurance benefits be charged to expense during the years that the employees
render service rather than the Registrant's practice, prior to 1992, of
recognizing these costs on a cash basis.  The January 1, 1992 noncash
cumulative charge for the adoption of this standard was $86.1 million, or $1.47
per share, after income taxes of $24.9 million.  This charge represents the
discounted present value of expected future benefits attributed to employees'
service rendered prior to January 1, 1992.  The adoption of this accounting
principle also reduced 1992 pre-tax income by approximately $6.0 million.  The
amount of claims paid for these benefits was approximately $7.2 million, $5.5
million and $3.9 million during 1993, 1992 and 1991, respectively.

                                  Income Taxes

SFAS No. 109 requires a change from the deferred method to the liability method
of accounting for income taxes.  Under the liability method, deferred income
taxes are recognized for the tax consequences of "temporary differences" by
applying enacted statutory tax laws and rates applicable to future years to
differences between the financial statement carrying amounts and the tax bases
of existing assets and liabilities.  Under this standard, the effect on
deferred taxes of a change in tax rates is recognized in income in the period
that includes the enactment date.  Under the deferred method, deferred taxes
were recognized using the tax rate applicable to the year of the calculation
and were not adjusted for subsequent changes in tax rates.  The January 1, 1992
noncash cumulative credit recognized as income for the adoption of this
standard was $22.6 million, or $.39 per share.  The adoption of SFAS No. 109
reduced 1992 pre-tax income from continuing operations by $3.4 million.

Cash Equivalents

For purposes of the Consolidated Statements of Cash Flows, "cash" includes cash
and cash equivalents. The Registrant considers liquid investments purchased
with a maturity of three months or less to be cash equivalents.  Because of the
short maturity of those investments, their carrying amount approximates fair
value.

Inventories

Inventories are valued at lower of cost or market. The majority of the
Registrant's U.S. inventories, other than maintenance and operating supplies,
are stated at last-in, first-out ("LIFO") cost and all other inventories are
valued at average cost.

Property, Plant and Equipment

Depreciation of property, plant and equipment is computed for financial
reporting purposes using the straight-line method over the estimated useful
lives of the assets.  These lives range from three years on light mobile
equipment to forty years on certain buildings. Land and mineral





                                    II - 33

<PAGE>   58
deposits include depletable raw material reserves on which depletion is
recorded using a units-of-production method.

Excess of Cost Over Net Assets of Businesses Acquired

The excess of cost over fair value of net assets of businesses acquired is
amortized on a straight-line basis over periods not exceeding forty years. The
amortization recorded for 1993, 1992 and 1991 was $4.3 million, $5.4 million
and $6.4 million, respectively. Accumulated amortization at December 31, 1993
and 1992 was $38.2 million and $33.9 million, respectively.

Research and Development

The Registrant is committed to improving its manufacturing process, maintaining
product quality and meeting existing and future customer needs.  These
objectives are pursued through various programs. Research and development
costs, which are charged to expense as incurred, were $7.3 million, $8.1
million and $7.5 million for 1993, 1992 and 1991, respectively.

Interest

No interest was capitalized during 1993, 1992 or 1991.  Interest income of $5.3
million, $4.5 million and $3.3 million, has been applied against interest
expense for 1993, 1992 and 1991, respectively.  The interest differential to be
paid or received as a result of interest rate swaps is accrued as interest
rates change and recognized over the life of the agreements as an adjustment to
interest expense.

Net Income Per Common Equity Share

The calculation of net income per common equity share is based on the weighted
average number of the Registrant's Common Shares and the Exchangeable
Preference Shares of LCI ("Exchangeable Shares") outstanding in each period and
the assumed exercise of stock options.  The weighted average number of shares
and share equivalents outstanding was (in thousands) 61,636, 58,652 and 55,925
in 1993, 1992 and 1991, respectively.  The computation of fully diluted
earnings per share was antidilutive in 1993, 1992 and 1991.


Other Postemployment Benefits

In December 1992, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 112, "Accounting for Other Postemployment
Benefits."  SFAS No. 112 requires the accrual of the estimated cost of benefits
provided to former or inactive employees after employment but before
retirement.  These benefits include long-term disability, temporary disability
income, medical coverage continuation and COBRA medical coverage continuation.
This new standard, which the Registrant must adopt by 1994, requires that the
expected cost of these benefits be charged to expense during the years that the
employees render service.  The Registrant will adopt this new





                                    II - 34

<PAGE>   59
standard on January 1, 1994.  The impact of adopting this standard will not be
material to the Registrant's financial position and operating results.


RESTRUCTURING

In the fourth quarter of 1993, the Registrant recorded a one-time pre-tax
restructuring charge of $21.6 million ($16.4 million net of tax benefits, or
$.27 per share) to cover the direct expenses of restructuring the Registrant's
North American business units to increase organizational efficiency.  The
primary components of the restructuring charge are separation benefits for
approximately 350 employees, employee relocation costs and early retirement
benefits for eligible employees electing early retirement.  The charge also
includes expenses such as office relocation and lease termination.

The restructuring plan entails the consolidation of eleven regional operating
units into six units in the Registrant's two main business lines.  This
consolidation reduces management layers, eliminates duplicative administrative
functions and standardizes procedures and information systems.  Manufacturing
and distribution facilities will not be materially affected by the
restructuring.

</TABLE>


The fair value of long-term debt at December 31, 1993 was approximately $428.0
million.  This fair value was estimated based upon quoted market prices or
current interest rates offered to the Registrant for debt of the same maturity.
The Registrant, does not generally anticipate the refinancing of these
obligations prior to maturity.





                                    II - 38

<PAGE>   63
The Registrant is a party to $98 million net notional amount of interest rate
swap agreements which have effectively fixed the interest rates on its floating
rate debt. The fixed rates payable under these agreements have a weighted
average of 9.3 percent with terms expiring at various dates from 1996 through
2000.

The Registrant is exposed to credit loss in the event of nonperformance by the
other parties to the interest rate swap agreements, but does not anticipate
nonperformance by such parties.  Based on current market interest rates, the
net termination cost at December 31, 1993 for the Registrant to unwind its
various hedging positions was approximately $17.0 million.

Annual principal payment requirements on long-term debt for each of the five
years in the period ending December 31, 1998, after the exclusion of short-term
bank loans for which anticipated refinancing is available, are as follows (in
millions):

Effective December 15, 1993, the Registrant extended the maturity of its $200
million revolving credit facility to December 1996.  At the end of 1993, no
amounts were outstanding under the revolving credit facility.  The Registrant
is required to pay annual commitment fees of up to one-quarter of one percent
of the unused portion of the funds available for borrowing under these credit
agreements.  There was approximately $11.1 million of short-term debt backed by
the revolving credit facility outstanding at December 31, 1993.  The revolving
credit facility and several other off-balance sheet arrangements are generally
at market conditions.

The Registrant's debt agreements require the maintenance of certain financial
ratios relating to cash flow, leverage, working capital and net worth.  At
December 31, 1993, the Registrant was in compliance with these requirements.

</TABLE>


PREFERRED STOCK

At December 31, 1990, there were 9.0 million shares of the Registrant's Third
Preferred Stock authorized, of which 1 million were outstanding.  These shares
were issued at a par value of $1.00 per share and were held by Lafarge Coppee.
The holders were entitled to one vote per share.  The shares were not entitled
to any equity participation or dividends and had a cash redemption and
liquidation value of $.25 per share. The Third Preferred Stock had certain
mandatory redemption provisions and all outstanding shares were redeemed under
these provisions on December 31, 1991.  The Registrant's charter provides that
redeemed shares of Third Preferred Stock automatically become authorized but
unissued shares of Common stock.


COMMON EQUITY INTERESTS

Holders of Exchangeable Shares have voting, dividend and liquidation rights
which parallel those of holders of the Registrant's Common Shares.  The
Exchangeable Shares are exchangeable into the Registrant's Common Shares on a
one-for-one basis.  Dividends on the Exchangeable Shares are cumulative and
payable at the same time as any dividends declared on the Registrant's Common
Shares.  The Registrant has agreed not to pay dividends on its Common Shares
without causing LCI to declare an equivalent dividend in Canadian dollars on
the Exchangeable Shares.  Dividend payments and the exchange rate on the
Exchangeable Shares are subject to adjustment from time to time to take into
account certain dilutive events.

At December 31, 1993 the Registrant had reserved for issuance approximately
13.4 million Common Shares to allow for the exchange of outstanding
Exchangeable Shares.  Additional common equity shares are reserved to cover
grants under the Registrant's stock option program (3.3 million), employee
stock purchase plan (.8 million), conversion of the Convertible Debentures (4.5
million) and issuances pursuant to the Registrant's optional stock dividend
plan (.5 million).

<PAGE>   65
In February 1992, the Registrant sold 1.7 million Exchangeable Shares that it
had accumulated through exchange transactions for net proceeds of $25.8
million.

On October 13, 1993, the Registrant sold 6.75 million Common Shares for $18.25
per share with net proceeds of $117.6 million.  Lafarge Coppee, the
Registrant's majority shareholder, purchased 1.0 million of these shares.


OPTIONAL STOCK DIVIDEND PLAN

The Registrant has an optional stock dividend plan which permits holders of
record of common equity shares to elect to receive new common equity shares
issued as stock dividends in lieu of cash dividends on such shares. The common
equity shares are issued under the plan at 95 percent of the average market
price, as defined in the plan.


STOCK OPTION AND PURCHASE PLANS

Options to purchase the Registrant's Common Shares and Exchangeable Shares have
been granted to key employees of the Registrant at option prices based on the
market price of the securities at the date of grant. One-fourth of the options
granted are exercisable at the end of each year following the date of grant,
and all the options granted are exercisable in four years. The options expire
ten years from the date of grant.

Effective January 1, 1992 the Registrant adopted SFAS No. 109 "Accounting for
Income Taxes."  The cumulative effect of this accounting change is reported in
the Consolidated Statements of Income.

Deferred income taxes for 1993 and 1992 reflect the tax consequences of
"temporary differences" between the financial statement carrying amounts and
the tax bases of existing assets and liabilities.  These temporary differences
are determined in accordance with SFAS No. 109 and are more

Upon adoption of SFAS No. 109, effective January 1, 1992, the Registrant
determined a valuation allowance requirement in the amount of $46.5 million.
During 1993 and 1992, the valuation allowance increased to $68.1 million and
$66.2 million, respectively, due primarily to the increase in unutilized net
operating losses in 1992.

In 1991 and prior years, deferred income taxes resulted from timing differences
in the recognition of revenues and expenses for tax return and financial
reporting purposes.  The primary timing difference was caused by tax
depreciation less than book depreciation.

At December 31, 1993, cumulative undistributed earnings of LCI were $546.9
million.  No provision for U.S. income taxes or Canadian withholding taxes has
been made since the Registrant considers the undistributed earnings to be
permanently invested in Canada.  The Registrant believes that such earnings, if
repatriated, would not result in significant U.S. income taxes because of tax
planning alternatives but would incur a Canadian withholding tax of ten percent
of the amount remitted.

The Registrant's U.S. federal tax liability has not been finalized by the
Internal Revenue Service for any year subsequent to 1983 due to the existence
of tax net operating loss and credit carryforwards.  The Registrant's Canadian
federal tax liability for all taxation years through 1989 has been reviewed and
finalized by Revenue Canada Taxation except for certain transactions for the
tax years 1984 through 1989 which are currently being reviewed.


SEGMENT INFORMATION

The Registrant's single business segment includes the manufacture and sale of
cement and ready-mixed concrete, precast and prestressed concrete components,
concrete block and pipe, aggregates, asphalt and reinforcing steel. In

Sales between the United States and Canada are accounted for at fair market
value. Income from operations equals net sales plus other income less cost of
goods sold, selling and administrative expenses and, in 1993, restructuring
charges.  It also excludes interest expense and income taxes. Financial

PENSION PLANS

The Registrant has several defined benefit and defined contribution retirement
plans covering substantially all employees. Benefits paid under the defined
benefit plans are based generally either on years of service and the employee's
compensation over the last few years of employment or years of service
multiplied by a contractual amount. The Registrant's funding policy is to
contribute amounts that are deductible for income tax purposes.

The following table summarizes the consolidated funded status of the
Registrant's defined benefit retirement plans and provides a reconciliation to
the consolidated prepaid pension asset recorded on the Registrant's
Consolidated Balance Sheets at December 31, 1993 and 1992(in millions). For
1993 the assumed settlement interest rate  was 7.5 percent for the Registrant's
U.S. plans and 8.0 percent for the Canadian plans.  For 1992, the assumed
settlement rate was 8.0 percent for the Registrant's U.S. plans and 8.5 percent
for the Canadian plans.  For 1993, the assumed rate of increase in future
compensation levels used in determining the actuarial present value of the
projected benefit obligations was 4.5 percent.  The 1992 rate was 5.0 percent.
The expected long-term rate of investment return on pension assets, which
include listed stocks, fixed income securities and real estate, was 9.0 percent
for each year presented.

Certain employees are also covered under multi-employer pension plans
administered by unions. Amounts included in the preceding table as defined
benefit plans retirement cost and contributions to such plans were $3.5
million, $3.5 million and $3.4 million for 1993, 1992 and 1991, respectively.
The data available from administrators of the multi-employer plans are not
sufficient to determine the accumulated benefit obligation, nor the net assets
attributable to the multi-employer plans in which Registrant employees
participate.

The defined contribution plans costs in the preceding table relate to thrift
savings plans for eligible U.S. employees in 1991 and for all eligible U.S. and
Canadian employees in 1992 and 1993.  Under the provisions of the plans, the
Registrant contributes an amount proportionate to each participant's salary and
will also match a portion of each participant's contribution.


OTHER POSTRETIREMENT BENEFITS

Effective January 1, 1992 the Registrant adopted SFAS No. 106, "Employers'
Accounting for Postretirement Benefits Other than Pensions."  The cumulative
effect of this accounting change is reported in the Consolidated Statements of
Income.

The Registrant provides certain retiree health and life insurance benefits to
eligible employees who retire in the U.S. or Canada.  Salaried participants
generally become eligible for retiree health care benefits when they retire
from active service at age 55 or later, although there are some variances by
plan or unit in Canada and the U.S.  Benefits, eligibility and cost-sharing
provisions for hourly employees vary by location and/or bargaining unit.
Generally, the health plans pay a stated percentage of most medical/dental
expenses reduced for any deductible, co-payment and payments made by government
programs and other group coverage.  These plans are unfunded.  An eligible
retiree's health care benefit coverage is coordinated in Canada with Provincial
Health and Insurance Plans and in the U.S., after attaining age 65, with
Medicare.  Certain retired employees of businesses acquired by the Registrant
are covered under other care plans that differ from current plans in coverage,
deductibles and retiree contributions.

In the U.S., salaried retirees and dependents under age 65 have a $1,000,000
health care lifetime maximum benefit.  At age 65 or over, the maximum is
$50,000.  Lifetime maximums for hourly retirees are governed by the location
and/or bargaining agreement in effect at the time of retirement.  In Canada,
some units have maximums, but in most cases there are no lifetime maximums.  In
some units in Canada, spouses of retirees have lifetime medical coverage.

In Canada, both salaried and nonsalaried employees are generally eligible for
life insurance benefits.  In the U.S., life insurance is provided for a number
of hourly retirees as stipulated in their hourly bargained agreements, but not
for salaried retirees except those of certain acquired companies.

The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation differs between U.S. and Canadian plans.  For
plans in both the U.S. and Canada, the pre-65 assumed rate was 13.4 percent
decreasing to 5.5 percent over 14 years.  For post-65 retirees in the U.S., the
assumed rate was 8.8 percent decreasing to 5.5 percent  over 14 years with a
Medicare assumed rate for the same group of 7.9 percent decreasing to 5.5
percent over 14 years.  For post-65 retirees in Canada, the assumed rate was
11.6 percent decreasing to 5.5 percent over 14 years.  If the health care cost
trend rate assumptions were increased by 1 percent, the accumulated
postretirement benefit obligation as of December 31, 1993 would be increased by
11.7 percent.  The effect of this change on the net periodic postretirement
benefit cost for 1993 would be an increase of 13.3 percent.

During 1989 and 1990, CSX Transportation, Inc., Metro-North Commuter Railroad
Company, National Railroad Passenger Corp., Peerless Insurance Company and
Massachusetts Bay Transit Authority (the "Railroads") filed actions against
Lone Star Industries Inc. and affiliates ("Lone Star") for damages resulting
from its fabrication and sale of allegedly defective concrete railroad ties to
the Railroads. The Registrant and LCI have been named in third party actions in
which Lone Star is claiming indemnity for liability to the Railroads, for
damages to its business and for costs and losses suffered as a result of the
Registrant and LCI supplying allegedly defective cement used by Lone Star in
the fabrication of the railroad ties. The damages claimed total approximately
$226.5 million. The Registrant denied the allegations and vigorously defended
against the lawsuits (the "Lone Star Case"). During September and October 1992,
Lone Star entered into agreements with all five plaintiff Railroads settling
their claims regarding the Lone Star Case for an amount totalling approximately
$66.7 million. These settlements have been submitted to and approved by the
United States Bankruptcy Court for the Southern District of New York which is
handling the Lone Star bankruptcy. Lone Star commenced trial in November 1992
in its third party complaint against the Registrant and LCI seeking indemnity
for the Railroads' claims in addition to its own claim for business
destruction. A jury verdict in this case reached in December 1992 awarded Lone
Star $1.2 million as damages. Both Lone Star and the Registrant and LCI have
appealed the trial court verdict to the United States Court of Appeals for
Fourth Circuit. A decision is expected in the near future.

In late 1990 Nationwide Mutual Insurance Company ("Nationwide"), one of the
Registrant's primary insurers during the period when allegedly defective cement
was supplied to Lone Star by the Registrant, filed a





                                    II - 51

<PAGE>   76
complaint for declaratory judgement against the Registrant, several of its
affiliates and eleven other liability insurers of the Registrant (the "Coverage
Suit").  The complaint seeks a determination of all insurance coverage issues
impacting the Registrant in the Lone Star Case.  The Registrant has answered
the complaint, counterclaimed against Nationwide, cross-claimed against the
co-defendant insurers and filed a third party complaint against 36 additional
insurers. In December 1991, the Registrant and Nationwide entered into a
settlement agreement pursuant to which Nationwide settled its claim in the
Coverage Suit and, among other things, paid the Registrant a portion of past
due defense expenses in the Lone Star Case, promised to pay its proportion of
continuing defense expenses therein and to post the entire remaining aggregate
limits of its policies as reserves to be used in the Lone Star Case, if
necessary. Virtually all of LCI's Canadian insurers involved in the Coverage
Suit filed motions for summary judgment. In January 1993, the court denied all
of the insurers' summary judgment motions. In January 1994 the Registrant filed
motions for partial summary judgment regarding the insurers' defense
obligations and regarding the reasonableness of fees and expenses included in
the defense of the Lone Star Case. In addition, the Registrant filed a motion
to strike the designation of several expert witnesses of the insurers. The
Registrant believes that it has substantial insurance coverage that will
respond to a large portion of defense expenses and liability, if any, in the
Lone Star Case.

During 1992, a number of owners of buildings located in Eastern
Ontario, Canada most of whom are residential homeowners, filed actions in the
Ontario Court (General Division) against Bertrand & Frere Construction Company
Limited ("Bertrand") and a number of other defendants seeking damages as a
result of allegedly defective footings, foundations and floors made with
ready-mixed concrete supplied by Bertrand. The largest of these cases involves
claims by approximately 99 plaintiffs owning 53 homes, a 20-unit condominium
building and a municipal building. Together, these plaintiffs are claiming
approximately Cdn. $40 million against Bertrand, each plaintiff seeking Cdn.
$200,000 for costs of repairs and loss of capital value of their respective
home or building, Cdn. $200,000 for punitive and exemplary damages and Cdn.
$20,000 for hardship, inconvenience and mental distress, together with interest
and costs. Other owners, owning a total of 13 buildings (of which 11 are
residential homes), have instituted similar suits against Bertrand and, based
on the information available at this time, these claims total approximately
Cdn. $9 million. As of the end of December 1993, LCI has been served with
third- or fourth-party claims by Bertrand in all but one of the referenced
lawsuits. Bertrand is seeking indemnity for its liability to the owners as a
result of the supply by LCI of allegedly defective flyash. LCI also supplied
cement to Bertrand. It is expected that Bertrand will file a third-party claim
against LCI in the other case as well.  LCI has delivered its statements of
defense. The discoveries are to begin in February 1994.  LCI has denied
liability and will defend the lawsuits vigorously. The Registrant believes it
has substantial insurance coverage that will respond to defense expenses and
liability, if any, in the said lawsuits.

The Registrant is involved in certain environmental enforcement matters
including being notified by the EPA that it is one of several potentially
responsible parties for clean-up costs at waste disposal sites.  The Registrant
accrues for fines, penalties and/or costs of remedial actions when it believes
it has a responsibility for the enforcement matter.  The ultimate costs related
to all such matters and the Registrant's degree of responsibility, in some of
these matters, is not presently determinable.  In addition, the Registrant is
involved in certain other legal actions and claims. It is the opinion of
management that such legal and environmental matters will be resolved without
material effect on the Registrant's Consolidated Financial Statements.


RELATED PARTY TRANSACTIONS

The Registrant is a participant in agreements with Lafarge Coppee for the
sharing of certain costs incurred for technical, research and managerial
assistance and for the use of certain trademarks.  The net expenses accrued for
these services were $4.8 million, $5.3 million and $5.4 million during 1993,
1992 and 1991, respectively.  In addition, the Registrant purchases various
products from Lafarge Coppee. Such purchases totaled $6.3 million, $17.1
million and $27.5 million in 1993, 1992 and 1991, respectively.  All
transactions with Lafarge Coppee were conducted on an arms-length basis.

Lafarge Coppee reinvested a portion of dividends it was entitled to receive on
the Registrant's Common Shares during 1993, 1992 and 1991.  These reinvestments
totaled $3.0 million, $8.9 million and $9.2 million, respectively.

At year-end, $15 million of the Registrant's 7% Convertible Debentures were
held by Lafarge Coppee.

In 1993, Lafarge Coppee purchased 1.0 million Common Shares as part of the
Registrant's equity offering of 6.75 million Common Shares.  The price paid for
these shares was the price to the public.   (See Common Equity Interests).

MANAGEMENT'S REPORT ON FINANCIAL REPORTING RESPONSIBILITY


Management is responsible for the preparation, integrity and objectivity of the
consolidated financial statements of Lafarge Corporation and subsidiaries and
other information contained in this Annual Report.  This responsibility
includes the selection of accounting procedures and practices, which are in
accordance with generally accepted accounting principles.  The consolidated
financial statements have been prepared in conformity with these procedures and
practices applied on a consistent basis.  These consolidated financial
statements reflect informed judgments and estimates, which management believes
to be reasonable, in the determination of certain data used in the accounting
and reporting process.

The Registrant maintains an effective system of internal accounting controls
which is periodically modified and improved to correspond with changes in the
Registrant's operations.  An important element of the system is an ongoing
internal audit function, which has direct access to the Audit Committee of the
Board of Directors.  The internal audit staff coordinates its audit activities
with the Registrant's independent public accountants, Arthur Andersen & Co., to
maximize audit effectiveness.

The Board of Directors, acting through its Audit Committee, monitors the
accounting affairs of the Registrant and has approved the consolidated
financial statements.  The Audit Committee, consisting of five outside
directors, reviews audit plans and results as well as the actions taken by
management in discharging its responsibilities for accounting, financial
reporting and internal control systems and recommends to the Board of Directors
the appointment of the independent public accountants.  The Audit Committee
meets periodically and privately with management, internal auditors and the
independent public accountants to assure that each is carrying out its
responsibilities.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Lafarge Corporation:

We have audited the accompanying consolidated balance sheets of Lafarge
Corporation (a Maryland corporation) and subsidiaries as of December 31, 1993
and 1992, and the related consolidated statements of income, cash flows, and
shareholders' equity for each of the three years in the period ended December
31, 1993.  These financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements based on our audits.

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

In our opinion, the financial statements referred to above (appearing on pages
II-28 through II-53) present fairly, in all material respects, the financial
position of Lafarge Corporation and subsidiaries as of December 31, 1993 and
1992, and the results of their operations and cash flows for each of the three
years in the period ended December 31, 1993, in conformity with generally
accepted accounting principles.

As discussed in the notes to the consolidated financial statements, effective
January 1, 1992, the Company changed its method of accounting for
postretirement benefits other than pensions and for income taxes.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To Lafarge Corporation:

We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements of Lafarge Corporation included in this Form
10-K and have issued our report thereon dated January 27, 1994.  Our audits
were made for the purpose of forming an opinion on those statements taken as a
whole.  The consolidated schedules (Schedules II, V, VI, VIII and X) are the
responsibility of the company's management and are presented for the purposes
of complying with the Securities and Exchange Commission's rules and are not
part of the basic financial statements.  These consolidated schedules have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, fairly state in all material respects
the financial data required to be set forth therein in relation to the basic
financial statements taken as a whole.

Chairman of the Board, the Vice Chairman of the Board, the President and Chief
Executive Officer, a majority of the Board of Directors or by any other person
specified in the Charter. Special meetings of the stockholders shall also be
called by the Secretary upon

<PAGE>   3
the written request of stockholders entitled to cast at least twenty-five per
cent (25%) of all the votes entitled to be cast at such meeting; provided,
however, that a special meeting need not be called to consider any matter which
is substantially the same as a matter voted on at any special meeting of the
stockholders held during the preceding twelve (12) months, unless a meeting is
requested by stockholders entitled to cast a majority of all the votes entitled
to be cast at such meeting. In any case in which a special meeting is called by
written request of the stockholders, such request shall state the purpose of
the meeting and the matters proposed to be acted on at it.

        SECTION 1.03.  Place of Meetings.  Except as limited by statute, all
meetings of stockholders shall be held at such place within or without the
State of Maryland as shall be determined from time to time by the Board of
Directors and stated in the notice of meeting.

        SECTION 1.04.  Notice of Meetings.  Except as provided below, not less
than ten (10) days nor more than ninety (90) days before the date of every
stockholders' meeting, the Secretary shall give to each stockholder entitled to
vote at such meeting, and to each stockholder not entitled to vote who is
entitled by statute to notice, written or printed notice stating the time and
place of the meeting and, in the case of a special meeting or if otherwise
required by statute, the purpose or purposes for which the meeting is called,
either by mailing it to him at his address as it appears on the records of the
corporation or by delivering it to him personally or by leaving it at his
residence or usual place of business. If a special meeting is called by the
stockholders, the Secretary shall inform the stockholders who make the





                                       2

<PAGE>   4
request of the reasonably estimated cost of preparing and mailing a notice of
the meeting, and on payment of these costs to the Corporation shall notify each
stockholder entitled to notice of the meeting. If mailed, such notice shall be
deemed to be given when deposited in the United States mail addressed to the
stockholder at his post office address as it appears on the records of the
Corporation, with postage thereon prepaid. Notwithstanding the foregoing
provisions, a written waiver of any required notice regarding any stockholder
meeting, signed by the person or persons entitled to such notice, whether
before or after the holding thereof, and filed with the records of the meeting,
or by actual attendance at the meeting in person or by proxy, shall be deemed
equivalent to the giving of such notice to such person.

        SECTION 1.05.  Conduct of Meetings.  Meetings of stockholders shall be
presided over by the Chairman of the Board, or, if he is not present, by the
Vice Chairman of the Board, or, if he is not present, by the President and
Chief Executive Officer, or, if he is not present, by a Vice President, or, if
none of said officers is present, by a chairman to be elected at the meeting.
The Secretary or, if he is not present, any Assistant Secretary, shall act as
secretary of such meetings; in the absence of the Secretary and any Assistant
Secretary, the presiding officer may appoint a person to act as secretary of
the meeting.

        SECTION 1.06.  Quorum.  Unless otherwise provided in the Charter, at
any meeting of stockholders the presence in person or by proxy of stockholders
entitled to cast a majority of the votes entitled to be cast thereat shall
constitute a quorum; but this Section shall not affect any requirement under
statute or under the Charter for the vote





                                       3

<PAGE>   5
necessary for the adoption of any measure. In the absence of a quorum, the
stockholders present in person or by proxy, by majority vote and without notice
other than by announcement, may adjourn the meeting from time to time until a
quorum shall attend. At any such adjourned meeting at which a quorum shall be
present, any business may be transacted which might have been transacted at any
meeting as originally notified. In the event that at any meeting a quorum
exists for the transaction of some business, but does not exist for the
transaction of other business, the business as to which a quorum is present may
be transacted by the holders of stock present in person or by proxy who are
entitled to vote thereon. Any meeting of stockholders, annual or special, may
adjourn from time to time to reconvene at the same or some other place at a
date not to exceed more than 120 days after the original record date, and no
notice need be given of any such adjourned meeting other than by announcement.

        SECTION 1.07.  Proxies.  A stockholder may vote the shares owned of
record by him either in person or by a written proxy signed by the stockholder
or by his duly authorized attorney-in-fact. No proxy shall be valid after
eleven (11) months from its date, unless otherwise provided in the proxy. A
proxy need not be sealed, witnessed or acknowledged.

        SECTION 1.08.  Votes Required.  A majority of the votes cast at a
meeting of stockholders, duly called and at which a quorum is present, shall be
sufficient to take or authorize action upon any matter which may properly come
before the meeting, unless otherwise provided by statute or by the Charter.
Unless the Charter provides for a greater or





                                       4

<PAGE>   6
lesser number of votes per share or limits or denies voting rights, each
outstanding share of stock, regardless of class, shall be entitled to one vote
on each matter submitted to a vote at a meeting of stockholders.

        SECTION 1.09.  Voting.  In all elections for directors every
stockholder shall have the right to vote, in person or by proxy, each share of
stock owned of record by him, for as many persons as there are directors to be
elected and for whose election the share is entitled to be voted. At all
meetings of stockholders, unless the voting is conducted by inspectors, the
proxies and ballots shall be received, and all questions touching the
qualification of the voters and the validity of proxies and the acceptance or
rejection of votes shall be decided by the chairman of the meeting. If demanded
by a stockholder or stockholders, present at a meeting, in person or by proxy,
entitled to cast ten per cent (10%) of the votes entitled to be cast thereat,
or if ordered by the chairman, the vote upon any election or question shall be
taken by ballot and, upon like demand or order, the voting shall be conducted
by two inspectors, in which event the proxies and ballots shall be received,
and all questions touching the qualification of voters and the validity of
proxies and the acceptance or rejection of votes, shall be decided by such
inspectors. Unless so demanded or ordered, no vote need be by ballot and voting
need not be conducted by inspectors. If inspections are demanded by the
stockholders or ordered by the chairman, the stockholders at any meeting may
choose an inspector or inspectors to act at such meeting, and in default of
such election the chairman of the meeting shall appoint such inspector or
inspectors.





                                       5

<PAGE>   7
No candidate for election as a director at a meeting shall serve as an
inspector thereat.

        SECTION 1.10.  Informal Action by Stockholders.  Any action required or
permitted to be taken at any meeting of stockholders may be taken without a
meeting if there is filed with the minutes of proceedings of stockholders a
unanimous written consent which sets forth the action and is signed by each
stockholder entitled to vote on the matter; and a written waiver of any right
to dissent signed by each stockholder entitled to notice of the meeting, but
not entitled to vote at it.

        SECTION 1.11.  Voting Rights of Certain Control Shares.
Notwithstanding any other provision of the Charter of the Corporation or these
By-laws, Title 3, Subtitle 7 of the Corporations and Associations Article of
the Annotated Code of Maryland (or any successor statute) shall not apply to
any acquisition by any person of shares of stock of the Corporation.  This
Section may be repealed, in whole or in part, at any time, whether before or
after an acquisition of control shares and, upon such repeal, may, to the
extent provided by any successor by-law, apply to any prior or subsequent
control share acquisition.

                               BOARD OF DIRECTORS

        SECTION 2.01.  Powers.  The business and affairs of the Corporation
shall be managed under the direction of its Board of Directors.  All powers of
the Corporation may be exercised by or under authority of the





                                       6

<PAGE>   8
Board of Directors, except as conferred upon or reserved to the stockholders by
statute, the Charter or the By-Laws.

        SECTION 2.02.  Number of Directors.  The number of directors of the
Corporation which shall constitute the whole Board shall be sixteen (16). By
vote of a majority of the entire Board of Directors, the number of directors
fixed by the Charter or by the By-Laws may be increased or decreased, from time
to time, not to exceed sixteen (16) nor to be less than three (3) directors,
but the tenure of office of a director shall not be affected by any decrease in
the number of directors so made by the Board. Directors need not be
stockholders in the Corporation or residents of the State of Maryland.

        SECTION 2.03.  Election of Directors.  At each annual meeting, the
stockholders shall elect directors to hold office until the next succeeding
annual meeting or until their successors are elected and qualify. At any
meeting of stockholders, duly called and at which a quorum is present, the
stockholders may, by the affirmative vote of the holders of a majority of the
votes entitled to be cast thereon, remove any director or directors from
office, except as otherwise provided by statute, and may elect a successor or
successors to fill any resulting vacancies for the unexpired terms of the
removed directors. In case such a removal occurs but the stockholders entitled
to vote thereon fail to fill any resulting vacancies, such vacancies may be
filled by the Board of Directors pursuant to Section 2.04. Any director may
resign at any time upon written notice to the Corporation.

        SECTION 2.04.  Vacancies.  Subject to Section 2.03, any vacancy
occurring in the Board of Directors for any cause other than by reason





                                       7

<PAGE>   9
of an increase in the number of directors may be filled by a majority of the
remaining members of the Board of Directors, although such majority is less
than a quorum. Any vacancy occurring by reason of an increase in the number of
directors may be filled by action of a majority of the entire Board of
Directors as constituted prior to such increase. A director elected by the
Board of Directors to fill a vacancy shall be elected to hold office until the
next annual meeting of the stockholders or until his successor is elected and
qualifies.

        SECTION 2.05.  Regular Meetings.  After each meeting of stockholders at
which a Board of Directors shall have been elected, the Board of Directors so
elected shall meet as soon as practicable for the purpose of organization and
the transaction of other business; and in the event that no other time is
designated by the stockholders, the Board of Directors shall meet promptly
following the close of such meeting on the day of such meeting. Such first
meeting shall be held at such place within or without the State of Maryland as
may be designated by the stockholders, or in default of such designation at the
place designated by the Board of Directors for such first regular meeting, or
in default of such designation at the place of the holding of the immediately
preceding annual meeting of stockholders. No notice of such first meeting shall
be necessary if held as hereinabove provided. Other regular meetings of the
Board of Directors may be held on such dates and at such places within or
without the State of Maryland as may be designated from time to time by the
Board of Directors and no additional notice of such regular meetings shall be
required.

        SECTION 2.06.  Special Meetings.  Special Meetings of the Board of





                                       8

<PAGE>   10
Directors may be called at any time by the Chairman of the Board, by the
President and Chief Executive Officer, or by a majority of the Board of
Directors by vote at a meeting, or in writing with or without a meeting. Such
special meetings shall be held at such place or places within or without the
State of Maryland as may be designated from time to time by the Board of
Directors.

        SECTION 2.07.  Notice of Meetings.  Notice of the place, day and hour
of every special meeting shall be given to each director at least forty-eight
(48) hours before the time of the meeting, by delivering the same to him
personally, by telephone, by telegraph, or by delivering the same at his
residence or usual place of business, or, in the alternative, by mailing such
notice no later than the seventh day preceding the day upon which the meeting
is to be held, postage paid, and addressed to him at his last known post office
address, according to the records of the Corporation; provided, however, that
if the person calling the meeting is of the opinion that the matters to be
considered thereat involve an emergency, notice of such meeting shall be given
by such means and within such time preceding the time at which the meeting is
to be held as the person calling the meeting shall in his discretion deem
reasonable and appropriate under the circumstances. Unless required by a
resolution of the Board of Directors, no notice of any meeting of the Board of
Directors and no waiver of notice of any such meeting need state the business
to be transacted thereat. No notice of any meeting of the Board of Directors
need be given to any director who attends such meeting, or to any director who
signs a waiver of notice of such meeting, either before or after the holding
thereof, and such waiver is





                                       9

<PAGE>   11
filed with the records of the meeting. Any meeting of the Board of Directors,
regular or special, may adjourn from time to time to reconvene at the same or
some other place, and no notice need be given of any such adjourned meeting
other than by announcement.

        SECTION 2.08.  Quorum.  At all meetings of the Board of Directors, a
majority of the entire Board of Directors, but in no event fewer than two (2)
directors, shall be necessary and sufficient to constitute a quorum for the
transaction of business. Except as otherwise provided by statute, by the
Charter or by the By-Laws, the affirmative vote of a majority of the directors
present at a meeting at which a quorum is present shall be necessary to elect
and pass any measure. In the absence of a quorum, the directors present by
majority vote and without notice other than by announcement may adjourn the
meeting from time to time until a quorum shall attend. At any such adjourned
meeting at which a quorum shall be present, any business may be transacted
which might have been transacted at the meeting as originally notified.

        SECTION 2.09.  Compensation.  The Board of Directors may provide for
the payment to directors of stated amounts annually for services incident to
serving as directors and committee members, or in the alternative, a fixed sum
for attendance at each meeting of the Board of Directors or committees thereof,
Directors shall be reimbursed by the Corporation for reasonable expenses
incurred in attending such meetings.  Except as otherwise provided by the Board
of Directors, the receipt of amounts or sums authorized hereby shall not
preclude any director from serving the Corporation in any other capacity and
receiving compensation therefor.

<PAGE>   12
        SECTION 2.10.  Informal Action by Directors.  Any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if a unanimous written
consent which sets forth such action is signed by all members of the Board of
Directors or of such committee, as the case may be, and such written consent is
filed with the minutes of proceedings of the Board of Directors or committee.

        SECTION 2.11.  Telephone Meetings.  Members of the Board of Directors
may participate in a meeting of such Board by means of a conference telephone
or similar communications equipment by means of which all persons participating
in the meeting can hear each other at the same time, and participation by such
means shall constitute presence in person at a meeting.

                                 ARTICLE III

                                  COMMITTEES

        SECTION 3.01.  Committees.  The Board of Directors may appoint from
among the directors an Executive Committee and such other committees, to
consist of such numbers of directors, not less than two, as the Board of
Directors may from time to time determine. The Board of Directors shall have
power at any time to remove any members of the Executive Committee and of each
other committee and to fill vacancies therein. When the Board of Directors is
not in session, the Executive Committee shall have and may exercise, in the
absence of or subject to any restrictions which the Board of Directors may from
time to time impose, all of the powers of the Board of Directors in the
management of the





                                       11

<PAGE>   13
business and affairs of the Corporation, except the power to declare dividends
or distributions on stock, to issue stock (except as provided by statute), to
recommend to stockholders any action requiring stockholders' approval, to amend
the By-Laws, or to approve any merger or share exchange which does not require
stockholder approval. Other committees shall have such powers, subject to
applicable law, as shall be designated by the Board of Directors from time to
time.

        SECTION 3.02.  Advisory Committees.  The Board of Directors may
designate such advisory committees from time to time as the Board of Directors,
in its discretion, deems necessary and proper, to perform such duties as may be
determined by the Board of Directors at the time of their designation or as may
be modified thereafter by the Board of Directors or the Executive Committee;
provided, however, that any such advisory committee or committees shall have
and may exercise only the power to recommend action to the Board of Directors
or the Executive Committee. Each advisory committee shall consist of two or
more individuals (with such alternates, if any, as may be deemed desirable)
selected by the Board of Directors, who may but need not be members of the
Board of Directors.

        SECTION 3.03.  Committee Meetings.  Meetings of any committee of
directors or advisory committee may be called by the Chairman of the Board or
the President and Chief Executive Officer of the Corporation or by any member
of the committee and may be held at any office of the Corporation or elsewhere,
as specified in the notice or waiver of notice of the meeting, upon not less
than twenty-four (24) hours notice by telephone or telegram (notice by telegram
shall be deemed given upon





                                       12

<PAGE>   14
delivery to the telegraph company), upon notice by mail if such notice is
mailed postage prepaid not later than the second day preceding the day upon
which the meeting is to be held, or upon written waiver of notice given before
or after the meeting; provided, however, that if the person calling the meeting
is of the opinion that the matters to be considered thereat involve an
emergency, notice of the meeting shall be given to each member by such means
and within such time preceding the time the meeting is to be held as the person
calling the meeting shall in his discretion deem reasonable and appropriate
under the circumstances. Notice of any meeting may be given by the Chairman of
the Board or the President and Chief Executive Officer of the Corporation, by
any member of the committee or by the secretary of the committee. Neither the
business to be transacted at, nor the purpose of, any meeting of a committee
need be specified in the notice or the waiver of notice of such meeting.
Members of any committee may participate in a meeting of the committee by means
of conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other, and participation
in a meeting through such means shall constitute presence in person at such
meeting. Any action required or permitted to be taken at any meeting of a
committee may be taken without a meeting if all members of the committee
consent thereto in writing filed with the minutes of the proceedings of the
committee. A majority of a committee shall constitute a quorum for the
transaction of business, and in the event a quorum is not present at any
meeting the member or members present may adjourn the meeting from time to time
without further notice until a quorum is present. Each committee





                                       13

<PAGE>   15
shall designate one of its members as chairman (except that the Chairman of the
Board of the Corporation shall act as Chairman of the Executive Committee) and
shall appoint a secretary (who need not be a member of the committee), who
shall keep minutes of its meetings. As soon as practicable, the minutes of each
meeting and any writing evidencing action by unanimous consent shall be
submitted to the Board of Directors, with or without a report, as such
committee may deem appropriate.

certificate is signed (1) by a transfer agent other than the Corporation or its
employee, or (2) by a registrar other than the Corporation or its employee, any
other signature on the certificate may be a facsimile.  In case any officer,
transfer agent, or registrar who has signed or whose facsimile signature has
been placed upon a certificate shall have ceased to be such officer, transfer
agent, or registrar before such certificate is issued, it may be issued by the
Corporation with the same effect as if he were such officer, transfer agent, or
registrar at the date of issue.

        SECTION 5.02.  Transfers of Stock.  Transfers of stock shall be made on
the books of the Corporation upon the surrender to the Corporation or a
transfer agent of a certificate for shares duly





                                       19

<PAGE>   21
endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, and the Corporation shall thereupon issue a new
certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books. The Board of Directors may appoint one
or more transfer agents and one or more registrars for any one or more classes
of the capital stock of the Corporation.

        SECTION 5.03.  Registered Stockholders.  The Corporation shall be
entitled to treat the holder of record of any share or shares of stock as the
holder in fact thereof and, accordingly, shall not be bound to recognize any
equitable or other claim to, or interest in, such shares in the name of any
other person, whether or not it shall have express or other notice hereof,
except as expressly provided by the laws of the State of Maryland.

        SECTION 5.04.  Record Dates.  The Board of Directors is hereby
empowered to fix, in advance, a date as the record date for the purpose of
determining stockholders entitled to notice of, or to vote at, any meeting of
stockholders, or stockholders entitled to receive payment of any dividend or
the allotment of any rights, or in order to make a determination of
stockholders for any other proper purpose. Except as otherwise provided by
statute, such date shall not be prior to the close of business on the day the
record date is fixed, and in any case shall be not more than ninety (90) days,
and in case of a meeting of stockholders, not less than ten (10) days, prior to
the date on which the particular action, requiring such determination of
stockholders, is to be taken. In lieu of fixing a record date, the





                                       20

<PAGE>   22
Board of Directors may provide that the stock transfer books shall be closed
for a stated period but not to exceed, in any case, twenty (20) days. If the
stock transfer books are closed for the purpose of determining stockholders
entitled to notice of or to vote at a meeting of stockholders, such books shall
be closed for at least ten (10) days immediately preceding such meeting.

        SECTION 5.05.  Stock Ledgers.  Original or duplicate stock ledgers,
containing the name and address of each stockholder of the Corporation and the
number of shares of each class held by each stockholder, shall be kept at the
principal executive office of the Corporation.

        SECTION 5.06.  Lost Certificates.  A new certificate or certificates
for shares of stock of the Corporation may, upon the making of an affidavit of
that fact by the person claiming a certificate of stock to be lost, stolen or
destroyed, be issued in such manner and under such conditions as the Board of
Directors may at any time or from time to time prescribe, to replace the
certificate alleged to have been lost, stolen or destroyed, provided that the
Board of Directors may, in its discretion, require the owner of any such
certificate, or his legal representatives, to give the Corporation a bond, with
sufficient surety to indemnify the Corporation against any claim that may be
made against it on account of the alleged loss, theft or destruction of any
such certificate or the issuance of a new certificate. A new certificate may be
issued without requiring any bond when in the judgment of the directors it is
proper so to do.

<PAGE>   29
        SECTION 7.10.  Reserves.  Before payment of any dividend there may be

                                  ARTICLE VIII

                                INDEMNIFICATION

        SECTION 8.01.  Required Indemnification of Directors.  The Corporation
shall indemnify any director made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (a "Proceeding"), unless it is proved that (1) the act or
omission of the director was material to the cause of action adjudicated in the
Proceeding and (i) was committed in bad faith or (ii) was the result of active
and deliberate dishonesty, (2) the director actually received an improper
personal benefit in money, property or services, or (3) in the case





                                       28

<PAGE>   30
of any criminal proceeding, the director had reasonable cause to believe that
the act or omission was unlawful. Indemnification may be against judgments,
penalties, fines, settlements, and reasonable expenses actually incurred by the
director in connection with the Proceeding; provided, however, if the
Proceeding was one by or in the right of the Corporation, indemnification may
not be made in respect of any Proceeding in which the director shall have been
adjudged to be liable to the Corporation. The termination of any Proceeding by
judgment, order or settlement does not create a presumption that the director
did not meet the requisite standard of conduct set forth in this Section.  The
termination of any Proceeding by conviction, or upon a plea of nolo contendere
or its equivalent or entry of an order of probation prior to judgment, creates
a rebuttable presumption that the director did not meet the requisite standard
of conduct set forth in this Section.

        SECTION 8.02.  Prohibited Indemnification of Directors.  A director
shall not be indemnified under Section 8.01 in respect if any Proceeding
charging improper personal benefit to the director, whether or not involving
action in the director's official capacity, in which the director was adjudged
to be liable on the basis that personal benefit was improperly received.

        SECTION 8.03.  Indemnification for Successful Defense.  Unless limited
by the Charter, a director who has been successful, on the merits or otherwise,
in the defense of any Proceeding referred to in Section 8.01 shall be
indemnified against reasonable expenses incurred by the director in connection
with such Proceeding.





                                       29

<PAGE>   31
        SECTION 8.04.  Determination that Indemnification is Proper.
Indemnification under Section 8.01 shall not be made by the Corporation unless
authorized for a specific Proceeding after a determination has been made that
indemnification of the director is permissible in the circumstances because the
director has met the standard of conduct set forth in Section 8.01. Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors not, at the time, parties to the Proceeding,
or, if such a quorum cannot be obtained, then by a majority vote of a committee
of the Board consisting solely of two or more directors not, at the time,
parties to such Proceeding and who were duly designated to act in the matter by
a majority vote of the full Board in which the designated directors who are
parties may participate, (2) by special legal counsel selected by the Board of
Directors or a committee of the Board by vote as set forth in (1) above, or, if
the requisite quorum of the full Board cannot be obtained therefor and the
committee cannot be established, by a majority vote of the full Board in which
directors who are parties may participate, or (3) by the stockholders.
Authorization of indemnification and determination as to reasonableness of
expenses shall be made in the same manner as the determination that
indemnification is permissible. However, if the determination that
indemnification is permissible is made by special legal counsel, authorization
of indemnification and determination as to reasonableness of expenses shall be
made in the manner specified for selection of such counsel. Shares held by
directors who are parties





                                       30

<PAGE>   32
to the Proceeding may not be voted on the subject matter under this Section.

        SECTION 8.05.  Payment of Expenses in Advance of Final Disposition.
Reasonable expenses incurred by a director who is a party to a Proceeding may
be paid or reimbursed by the Corporation in advance of the final disposition of
the Proceeding upon receipt by the Corporation of (1) a written affirmation by
the director of the director's good faith belief that the standard of conduct
necessary for indemnification by the Corporation has been met and (2) a written
undertaking by or on behalf of the director to repay the amount if it shall
ultimately be determined that the standard of conduct has not been met. The
undertaking required shall be an unlimited general obligation of the director
but need not be secured and may be accepted without reference to financial
ability to make the repayment. Payments under this Section shall be made as
provided by the Charter, these By-Laws or contract or as specified in Section
8.04.

        SECTION 8.06.  Expenses of Directors Incurred as a Witness. The
Corporation shall pay or reimburse expenses incurred by a director in
connection with an appearance as a witness in a Proceeding at a time when the
director has not been named as a defendant or respondent to the Proceeding.

        SECTION 8.07.  Director's Service to Employee Benefit Plan. For
purposes of this Article, (1) the Corporation shall be deemed to have requested
a director to serve an employee benefit plan where the performance of the
director's duties to the Corporation also imposes





                                       31

<PAGE>   33
duties on, or otherwise involves services by, the director to the plan or
participants or beneficiaries of the plan, (2) excise taxes assessed on a
director with respect to an employee benefit plan pursuant to applicable law
shall be deemed fines; and (3) action taken or omitted by the director with
respect to an employee benefit plan in the performance of the director's duties
for a purpose reasonably believed by the director to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose
which is not opposed to the best interests of the Corporation.

        SECTION 8.08.  Officers, Employees or Agents. Unless limited by the
Charter, (1) an officer of the Corporation shall be indemnified as and to the
extent provided in Section 8.03 for a director, (2) the Corporation may
indemnify and advance expenses to an officer, employee, or agent of the
Corporation or of any subsidiary of the Corporation or a director of such a
subsidiary to the same extent that it may indemnify directors of the
Corporation under this Article, and (3) the Corporation, in addition, may
indemnify and advance expenses to an officer, employee, or agent of the
Corporation or of any subsidiary of the Corporation or a director of such a
subsidiary who is not a director of the Corporation to such further extent,
consistent with law as may be provided by the Charter, the By-Laws, by action
of the Board of Directors or by contract.

        SECTION 8.09.  Insurance. The Corporation may purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee,
or agent of the Corporation or of any subsidiary





                                       32

<PAGE>   34
of the Corporation, or who, while a director, officer, employee, or agent of
the Corporation or of any subsidiary of the Corporation, is or was serving at
the request of the Corporation as a director, officer, partner, trustee,
employee, or agent of another foreign or domestic corporation, partnership,
joint venture, trust, other enterprise, or employee benefit plan against any
liability asserted against and incurred by such person in any such capacity or
arising out of such person's position, whether or not the Corporation would
have the power to indemnify against liability under the provisions of this
Article. The Corporation may provide similar protection, including a trust
fund, letter of credit, or surety bond, not inconsistent with this Section. The
insurance or similar protection provided pursuant to this Section may be
provided by a subsidiary or an affiliate of the Corporation.

        SECTION 8.10.  Report of Indemnification to Stockholders. Any
indemnification of, or advance of expenses to, a director in accordance with
this Article, if arising out of a Proceeding by or in the right of the
Corporation, shall be reported in writing to the stockholders with the notice
of the next stockholders' meeting or prior to the meeting.

        SECTION 8.11.  Terms. Terms used in this Article, which are not
otherwise defined herein, shall have the meaning set forth in Section 2-418 of
the General Corporation Law of the State of Maryland.

        SECTION 8.12.  Scope. The indemnification and advancement of expenses
provided or authorized by this Article shall not be deemed exclusive of any
other rights, by indemnification or otherwise, to





                                       33

<PAGE>   35
which a director, officer, employee or agent of the Corporation or of a
subsidiary of the Corporation may be entitled under the Charter, the By-Laws, a
resolution of stockholders or directors, an agreement or statute or otherwise,
as to action in an official capacity or as to action in another capacity while
holding such office, and the provisions of this Article shall not be construed
to in any way limit any such other rights.

                                   ARTICLE IX

                                    NOTICES

        SECTION 9.01.  Manner of Giving Notice. Whenever under the provisions
of the statutes or of the Charter or of the By-Laws, notice is required to be
given to any director or stockholder of the Corporation, and no provision is
made as to how such notice shall be given, it shall not be construed to mean
personal notice, but such notice may be given in writing, by mail, by
depositing the same in a post office or letter box, in a postpaid sealed
wrapper, addressed to such director or stockholder at such address as it
appears on the books of the Corporation, or, in default of other address, to
such director or stockholder at the General Post Office in the City of
Baltimore, Maryland, and such notice shall be deemed to be given at the time
when the same shall be thus mailed.

        SECTION 9.02.  Waiver of Notice. Whenever any notice is required to be
given under the provisions of the statutes or of the Charter, or of the
By-Laws, a waiver thereof in writing signed by the person or persons entitled
to said notice, whether before or after the





                                       34

<PAGE>   36
holding of the meeting or the taking of any other action referred to therein,
shall be deemed equivalent thereto.

                              LAFARGE CORPORATION

                             1993 STOCK OPTION PLAN



SECTION I.   PURPOSE

The purpose of the Lafarge Corporation 1993 Stock Option Plan (the "Plan") is
to encourage and enable key employees of Lafarge Corporation (the "Company")
and its subsidiary corporations ("Subsidiary" or "Subsidiaries") as defined
under Section 424(f) of the Internal Revenue Code of 1986, as amended (the
"Code"), upon whose judgment, initiative and efforts the Company largely
depends for the successful conduct of its business, to remain with and devote
their best efforts to the business of the Company, thereby advancing the
interests of the Company and its stockholders.  Accordingly, the Company may
grant to certain employees the option ("Option") to purchase shares of the
Common Stock of the Company, par value $1.00 per share ("Stock"), and may award
bonuses in the form of Stock subject to the restrictions set forth in Section
IX ("Restricted Stock"), as hereinafter set forth.  Options granted under the
Plan shall be nonqualified stock options which shall not be treated as
incentive stock options under Section 422 of the Code.


SECTION II.   ADMINISTRATION OF THE PLAN

The Plan shall be administered by a committee (the "Committee") of three or
more directors of the Company appointed by the Board of Directors.  Members of
the Committee shall not, within one year prior to their appointment to the
Committee, have been granted or awarded equity securities pursuant to the Plan
or pursuant to any other stock option or stock plan of the Company or any
parent or subsidiary corporation of the Company (an "Affiliate") within the
meaning of Section 425(e) and (f) of the Code.  The Committee shall have sole
authority to determine the employees who are to be granted Options or stock
appreciation rights or awarded Restricted Stock from among those eligible
hereunder and to establish the number of shares of Stock to be optioned to
each, the number of stock appreciation rights to be granted to each, and the
number of shares to be awarded to each in the form of Restricted Stock after
taking into consideration the position held, the duties performed, the
compensation received, the services expected to be rendered by such employee
and other relevant factors.  The Committee is authorized to interpret the Plan
and may from time to time adopt such rules and regulations, not inconsistent
with the provisions of the Plan, as it may deem advisable to carry out the
Plan. A majority of the Committee shall constitute a quorum and the acts of a
majority of the members present at any meeting at which a quorum is present, or
acts approved in writing by a majority of the Committee, shall be deemed the
acts of the Committee.  All decisions made by the Committee in selecting the
employees to whom Options and stock appreciation rights shall be granted or
Restricted Stock shall be awarded, in establishing the number of





                                       1

<PAGE>   3
shares which may be issued under each Option or awarded as Restricted Stock and
in construing the provisions of the Plan shall be final.  No member of the
Committee shall be liable for any action taken, failure to act, determination
or interpretation made in good faith with respect to the Plan or any Option or
stock appreciation right granted or Restricted Stock awarded under the Plan.


SECTION III.   SHARES SUBJECT TO THE PLAN

The aggregate number of shares of Stock issued under Options or awarded in the
form of Restricted Stock under this Plan shall not exceed 3,000,000 shares.
Such shares of Stock may consist of authorized but unissued shares of Stock or
previously issued shares of Stock reacquired by the Company.  Any of such
shares of Stock which remain unissued and which are not subject to outstanding
Options and have not been awarded in the form of Restricted Stock at the
termination of the Plan shall cease to be subject to the Plan.  Should any
Option hereunder expire or terminate prior to its exercise in full, or any
Stock previously awarded as Restricted Stock be forfeited, the shares of Stock
subject to such Option at the time of its expiration or termination and the
shares of Restricted Stock so forfeited will again be available for grant or
award under the Plan.  The aggregate number of shares of Stock which may be
issued under the Plan shall be subject to adjustment as provided in Section X
hereof.  Exercise of an Option in any manner, including an exercise involving
an election of an alternative settlement method referred to in Section VII
hereof, shall result in a decrease in the number of shares of Stock which may
thereafter be available for purposes of the Plan by the number of shares of
Stock as to which the Option is exercised.


SECTION IV.   ELIGIBILITY

The Committee shall determine and designate, at any time or from time to time,
the key personnel of the Company and the Subsidiaries to whom Options are to be
granted or Restricted Stock is to be awarded, but subject to the terms and
conditions set forth below:

(a)      Options may be granted and Restricted Stock may be awarded only to
         individuals who are key employees (including officers and directors
         who are also key employees) of the Company or a Subsidiary at the time
         the Option is granted or the Restricted Stock is awarded.  Options may
         be granted or Restricted Stock awarded to the same employee on more
         than one occasion.


(b)      The aggregate number of shares of Stock which may be issued under
         Options granted or Restricted Stock awarded under the Plan to any one
         individual shall not exceed 5% of the outstanding shares of Stock.





                                       2

<PAGE>   4
SECTION V.   OPTION PRICE

The Option price per share of Stock underlying each Option shall be fixed by
the Committee at the time the Option is granted, but shall not be less than
100% of the fair market value of the Stock at the time of the granting of the
Option.  For purposes of the Plan, the fair market value of Stock on any
particular date shall be determined by the Committee which may use any
reasonable method of valuation, including the mean of the high and low sales
prices of publicly traded shares of Stock on the date in question as reported
on the Composite Transactions reporting system or, if the Stock is listed on a
U.S. national securities exchange, the last sales price reported on such
exchange on that date.


SECTION VI.    OPTION TERM

The expiration date of an Option shall be determined by the Committee at the
time of grant, but shall in no event be later than ten years from the date of
grant.


SECTION VII.  OPTION AGREEMENTS

Each Option shall be evidenced by an option agreement ("Option Agreement") and
shall contain such terms and conditions not inconsistent with the provisions of
the Plan as may be approved by the Committee.  The terms and conditions of the
respective Option Agreements need not be identical and may be amended by the
Committee from time to time, subject to the provisions of the Plan.  Payment of
the purchase price of any Option exercised shall be made to the Company either
(i) in cash (including check, bank draft or money order) or (ii) by delivering
shares of Stock already owned by the optionee and which have been owned for at
least six (6) months, duly endorsed for transfer or (iii) a combination of such
Stock and cash.  The fair market value of any Stock so delivered shall be
determined on the same basis as provided in Section V hereof.  An Option
Agreement may provide for the surrender of the right to purchase shares of
Stock under the Option in return for a payment in cash or shares of Stock or a
combination of cash and shares of Stock equal to the excess of the fair market
value of the shares of Stock with respect to which the right to purchase is
surrendered over the Option price therefor, on such terms and conditions as the
Committee in its sole discretion may prescribe.


SECTION VIII.  EXERCISE OF OPTIONS

(a)      Each Option granted under the Plan shall be exercisable during such
         period commencing on or after the expiration of one year from the date
         of the grant of such Option as the Committee shall determine;
         provided, however, that the otherwise unexpired portion of any Option
         shall expire and become null and void no later than





                                       3

<PAGE>   5
         upon the first to occur of (i) the expiration of ten years from the
         date such Option was granted, (ii) the expiration of three months from
         the date of the termination of the optionee's employment with the
         Company or an Affiliate for any reason other than death, disability or
         retirement under the normal or early retirement provisions of a
         pension or retirement plan maintained by the Company or an Affiliate,
         or (iii) the expiration of three years from the date of the
         termination of the optionee's employment with the Company or an
         Affiliate by reason of death, disability or retirement under the
         normal or early retirement provisions of a pension or retirement plan
         maintained by the Company or an Affiliate.  Transfer of employment
         without interruption of service between or among the Company and its
         Affiliates shall not be considered to be a termination of employment
         for the purposes of this Plan.  Any provision of this Plan to the
         contrary notwithstanding, the otherwise unexpired portion of any
         Option granted hereunder shall expire and become null and void
         immediately upon an optionee's termination of employment with the
         Company or an Affiliate by reason of such optionee's fraud, dishonesty
         or performance of other acts detrimental to the Company or an
         Affiliate.

(b)      Each Option granted hereunder shall be exercisable in full or in such
         annual installments as may be determined by the Committee at the time
         of the grant; provided, however, that the Committee in its discretion
         may subsequently accelerate the exercise date of an Option.  The right
         to purchase shares of Stock shall be cumulative so that when the right
         to purchase any shares of Stock has accrued, such shares or any part
         thereof may be purchased at any time thereafter until the expiration
         or termination of the Option.

(c)      If the Committee grants stock appreciation rights in connection with
         an Option, either at the time of grant or by amendment, such right
         shall be subject to the same terms and conditions as the related
         Option and shall be exercisable only to the extent the Option is
         exercisable.  Stock appreciation rights shall be granted only in
         connection with an Option.  A right shall entitle the optionee to
         surrender to the Committee the related unexercised Option, or any
         portion thereof, and to receive from the Company in exchange therefor
         cash, shares of Stock, or a combination of cash and Stock, having an
         aggregate value equal to (i) the excess of the fair market value of
         one share of Stock over the Option price, times (ii) the number of
         shares of Stock called for by the Option, or portion thereof, which is
         surrendered.  The number of shares of Stock which may be received
         pursuant to the exercise of a right may not exceed the number of
         shares of Stock called for by the Option, or portion thereof, which is
         surrendered.  No fractional shares of Stock will be issued.  The
         Committee shall have the right to determine whether the Company's
         obligation shall be paid in cash, shares of Stock, or a combination of
         cash and Stock.  The Committee may establish a maximum appreciation
         value which would be awardable under any granted right or rights.





                                       4

<PAGE>   6
(d)      No Option or stock appreciation right granted under the Plan shall be
         transferable by the holder thereof otherwise than by will or by the
         laws of descent and distribution, and shall be exercisable during the
         lifetime of the optionee only by him.

(e)      Nothing in this Section shall operate to extend the period of exercise
         of an Option beyond the expiration date specified in the Option
         Agreement.


SECTION IX.  RESTRICTED STOCK

The Committee may from time to time, in its sole discretion, award bonuses in
the form of Restricted Stock to persons eligible to receive awards of
Restricted Stock under Section IV.  All Restricted Stock awarded under the Plan
shall be subject to such restrictions, terms and conditions, if any, as may be
determined by the Committee.  The Committee may in its sole discretion remove,
modify or accelerate the release of restrictions on any Restricted Stock in the
event of death or disability of the recipient of such Restricted Stock, or for
such other reasons as the Committee may deem appropriate.

Any certificate or certificates representing shares of Restricted Stock shall
bear a stamped or printed notice on the face thereof to the effect that such
shares have been awarded pursuant to the terms of the Plan and may not be sold,
pledged, transferred, assigned or otherwise encumbered in any manner except as
set forth in the terms of such award.  If the Committee so determines, the
certificates representing Restricted Stock shall be deposited by the recipient
with the Company or an escrow agent designated by the Company until the
restrictions thereon have lapsed or have been removed in accordance with the
provisions of this Section.  Upon the lapse of the restrictions or removal
thereof by the Committee, new unrestricted certificates for the number of
shares on which the restrictions have lapsed or been removed shall, upon
request by the recipient of the Restricted Stock, be issued in exchange for
such restricted certificates.

<PAGE>   7
SECTION X.   ADJUSTMENTS UPON RECAPITALIZATION OR REORGANIZATION

In the event the Company shall effect a split of the Stock or dividend payable
in Stock (other than pursuant to the Company's Optional Stock Dividend Plan),
or in the event the outstanding Stock shall be combined into a smaller number
of shares, the maximum number of shares of Stock as to which Options may be
granted and Restricted Stock may be awarded under the Plan shall be increased
or decreased proportionately.  In the event that before delivery by the Company
of all of the shares of Stock in respect of which any Option or stock
appreciation right has been granted under the Plan, the Company shall have
effected such a split, dividend or combination, the shares of Stock still
subject to the Option or stock appreciation right shall be increased or
decreased proportionately and the purchase price per share of Stock shall be
decreased or increased proportionately so that the aggregate purchase price for
all of the then optioned shares of Stock shall remain the same as immediately
prior to such split, dividend or combination.

In the event of a reclassification of the Stock not covered by the foregoing,
or in the event of a liquidation or reorganization, including a merger,
consolidation or sale of assets, the Board of Directors shall make such
adjustments, if any, as it may deem appropriate in the number and kind of
shares for which Options, stock appreciation rights or Restricted Stock may be
granted or awarded under the Plan and, with respect to outstanding Options and
stock appreciation rights, in the number, purchase price and kind of shares
covered thereby.  The provisions of this Section shall only be applicable if,
and only to the extent that, the application thereof does not conflict with any
valid governmental statute, regulation or rule.


SECTION XI.   CONTINUANCE OF EMPLOYMENT

Neither the Plan nor any agreement relating to any Option, stock appreciation
right or award of Restricted Stock shall impose any obligation on the Company
or an Affiliate to continue to employ any employee.


SECTION XII.   WITHHOLDING

The Company shall have the right to withhold taxes, as required by law, from
any transfer of cash or Stock to an employee under the Plan or to collect, as a
condition of such transfer, any taxes required by law to be withheld.

(a)      Subject to the provisions of paragraphs (b) and (c) of this Section,
         at any time when an employee is required to pay to the Company an
         amount required to be withheld under applicable tax laws in connection
         with an issuance of Stock upon exercise of an Option or stock
         appreciation right, the employee may satisfy this obligation in whole
         or in part by electing (the "Election") to





                                       6

<PAGE>   8
         have the Company withhold from the issuance shares of Stock having a
         fair market value equal to the amount required to be withheld.  The
         value of the shares of Stock to be withheld shall be based on the fair
         market value of such shares as of the date on which shares of Stock
         are issued to the employee pursuant to exercise of the Option or stock
         appreciation right (the "Tax Date").  The employee must pay to the
         Company any difference between the amount required to be withheld by
         the Company and the value of the shares of Stock so withheld.  Any
         shares of Stock withheld shall not thereafter be available to be
         subject to an Option granted under the Plan.

(b)      Each Election must be made prior to the Tax Date.  The Committee may
         disapprove of any Election, may suspend or terminate the right to make
         Elections and may provide with respect to any Option or stock
         appreciation right that the right to make Elections shall not apply to
         such Option or stock appreciation right.  An Election is irrevocable.

(c)      If an employee is an officer of the Company within the meaning of
         Section 16 of the Securities Exchange Act of 1934 and the rules and
         regulations promulgated thereunder, then an Election is subject to the
         following additional conditions:

         (1)     No Election shall be effective with respect to a Tax Date
                 which occurs within six months of the grant of the Option or
                 stock appreciation right, except that this limitation shall
                 not apply in the event the death or disability of the employee
                 occurs prior to expiration of the six-month period.

         (2)     The Election must be made either six months prior to the Tax
                 Date or during a period beginning on the third business day
                 following the date of release for publication of the Company's
                 quarterly or annual summary statements of sales and earnings
                 and ending on the twelfth business day following such date.


SECTION XIII.   AMENDMENT OR TERMINATION OF THE PLAN

The Board of Directors in its discretion may terminate the Plan at any time
with respect to any shares of Stock for which Options have not theretofore been
granted or which have not been awarded as Restricted Stock.  The Board of
Directors shall have the right to alter or amend the Plan or any part thereof
from time to time; provided, that no such change may be made which would impair
the rights of the optionee under any outstanding Option or the recipient of
Restricted Stock without the consent of such optionee or recipient; and
provided, further, that the Board of Directors may not make any alteration or
amendment which would materially increase the benefits accruing to participants
under the Plan, increase the aggregate number of shares of Stock which may be
issued pursuant to the provisions of the Plan, or materially modify the





                                       7

<PAGE>   9
requirements for participation in the Plan without the approval of the
stockholders of the Company.


SECTION XIV.   EFFECTIVENESS AND EXPIRATION OF THE PLAN

If adopted by the Board of Directors and approved by the vote of the holders of
a majority of the stock of the Company entitled to vote thereon at a meeting of
stockholders duly called and held for such purpose, or at an annual meeting
thereof, the notice of which has specified that action is to be taken on the
Plan, and the Committee shall have been advised by legal counsel for the
Company that in the opinion of such counsel all applicable requirements of law
precedent to its becoming effective have been fully met, then the Plan shall
become effective on August 4, 1993 or as soon thereafter as the aforesaid
requirements have been met.  The Plan shall expire five years after the
effective date of the Plan.  If the stockholders of the Company fail so to
approve the Plan, the Plan shall thereupon terminate and all Options previously
granted and all awards of Restricted Stock under the Plan shall become void and
of no effect. With respect to persons subject to Section 16 of Securities
Exchange Act of 1934 (the "1934 Act"), transactions under the Plan are intended
to comply with applicable conditions of Rule 16b-3 or its successors under the
1934 Act.  To the extent any provisions of the Plan or action by the Committee
fails to so comply, it shall be deemed null and void, to the extent permitted
by law and deemed advisable by the Committee.

                                  COMMON STOCK


         AGREEMENT, dated as of November 1, 1993 (the "Agreement"), between
Lafarge Corporation, a Maryland corporation (the "Company"), and Lafarge Coppee
S.A., a French corporation (the "Parent").

                              W I T N E S S E T H:

         WHEREAS, the Parent presently directly and indirectly holds shares of
the Company's Common Stock, $1.00 par value ("Common Stock") and 7% Convertible
Subordinated Debenture ("Debenture"), and Exchangeable Preference shares
("Exchangeable Shares") of the Company's subsidiary, Lafarge Canada Inc.
("LCI").

         WHEREAS, the Debentures are potentially convertible into Common Stock,
and the holders of Exchangeable Shares, through a trust holding Voting Stock,
$0.0001 par value ("Voting Stock"), of the Company ("Exchange Trust"), vote as
a class with the holders of Common Stock, and any other class or series of
capital stock of the Company having general voting rights in the Company;

         WHEREAS, the Parent presently directly and indirectly holds such
number of shares of Common Stock, Exchangeable Shares and Debentures so that
(assuming conversion of all outstanding Debentures) the Parent would directly
and indirectly hold shares entitling it to cast approximately 54.59% of the
total votes cast at a meeting of stockholders of the Company;

         WHEREAS, by virtue of its ownership of Common Stock and Exchangeable
Shares, the Parent has the power to elect all of the directors of the Company
and to control decisions to be voted upon by stockholders, except as otherwise
provided by law;

         WHEREAS, the loss of such voting control could have adverse
consequences for the Parent and the Company under certain laws of France,
Canada and the United States; and the Parent has informed the Company of its
intention to maintain such voting control for the foreseeable future;

         WHEREAS, the Parent, in consideration for benefits conferred upon the
Company by it, has requested that the Company agree as set forth herein;

         NOW, THEREFORE, in consideration of the premises and the mutual and
dependent promises hereinafter set forth, the parties hereto agree as follows:

SECTION 1.                Issuance of Relevant Voting Securities

         (a)     In the event that the Company shall from time to time issue to
any person other than the Parent any Relevant Voting Securities. as hereinafter
defined, the Parent shall have the right to purchase from the Company up to the
amount of such Relevant Voting Securities as shall be necessary to permit it to
achieve (on a basis assuming the exercise of all conversion, exchange and
similar rights of outstanding securities except employee stock options) a
control margin of 1,000,000 votes in excess of 50% of the Total Voting Power,
as hereinafter defined, to be represented by all Includible Voting Securities,
as hereinafter defined, to be outstanding (or deemed to be outstanding) after
such issuances by the Company and purchases by the Parent and the other
purchaser(s).

         "Voting Securities" shall mean all shares of Common Stock, Voting
Stock, and any other securities of the Company or of a subsidiary of the
Company (such as Exchangeable Shares) entitled to vote (regardless of whether
such voting rights (i) are presently exercisable or (ii) directly appertain to
such securities or (iii) are only available upon subsequent conversion, option
or warrant exercise, exchange or other disposition of such securities) on all
matters with holders of Common Stock and Voting Stock at meetings of the
stockholders of the Company.

         "Relevant Voting Security"shall mean any Voting Security other than
(i) Common Stock issuable upon exercise of the exchange rights of Exchangeable
Shares, (ii) Common Stock or other Voting Securities issuable upon exercise of
conversion or similar rights of an outstanding Includible Voting Security such
as issuable upon conversion of Debentures, (iii) Voting Securities issued, or
reserved for issuance, pursuant to a Stock Plan, as hereinafter defined, (iv)
securities covered by outstanding options under any Stock Plan which is an
employee Stock Plan, and (v) Voting Stock issued to the trustee under the
Exchange Trust as a consequence of the issuance of additional Exchangeable
Shares.

         "Total Voting Power" shall mean the total number of votes attributable
to all Includible Voting Securities of the Company.  For this purpose, the
number of shares of Voting Stock shall be calculated on the basis of the
maximum number of votes that could be cast at the time of determination under
the Indenture, assuming conversion of all Debentures into Common Stock, but the
Debentures shall not be added to the calculation.

         "Includible Voting Securities"shall mean all Voting Securities other
than (i) Common Stock issuable upon exercise of the exchange rights of
Exchangeable Shares or upon exercise of the conversion, exchange or similar
rights of other Includible Voting Securities, (ii) securities reserved for
issuance under any Stock Plan and (iii) securities covered by options under
employee Stock Plans.





                                       2

<PAGE>   4
         "Stock Plan" shall mean any employee stock purchase plan, profit
sharing plan, incentive, compensation or bonus plan, dividend reinvestment
plan, optional stock dividend plan, stock option plan or any other similar plan
either (i) approved by the Company's Board of Directors pursuant to which any
securities are issued by the Company to its stockholders or to employees of the
Company or a subsidiary, or (ii) approved by the Board of Directors of LCI
pursuant to which any securities are issued by LCI to its employees or
stockholders.

         For purposes of this Section 1(a), the issuance by a subsidiary of the
Company (to a person other than the Company) of securities which have the
rights of or are convertible into or exchangeable for Voting Securities, and
the sale by the Company of any securities issued by a subsidiary with the
aforesaid characteristics, shall be deemed to constitute an issuance of Voting
Securities by the Company.

         Nothing in this Agreement shall be construed to prevent or constrain
the Parent from acquiring outstanding shares of Common Stock, Exchangeable
Shares or any other securities of the Company or of any subsidiary on the open
market or otherwise.

         (b)  The Company shall notify the Parent in writing sufficiently in
advance of any proposed issue of Common Stock or other Relevant Voting Security
covered by the right to purchase granted to the Parent in Section 1(a) so that
the Parent, after its receipt of such notice but prior to any such issuance,
shall have a period of fifteen days to determine whether to exercise its right
to purchase shares of such Common Stock or other Relevant Voting Security (as
the case may be).  The Company's notice, to the extent information is known or
reasonably subject to estimation, shall include information as to the estimated
nature and date of the proposed issue and the estimated price and amount of
securities to be issued.  If the Parent, within the 15-day period, notifies the
Company (which notice shall specify whether the Parent intends to purchase all
or only a specified portion of the shares it could elect to acquire) of its
intention to exercise this right, then, simultaneously with, or immediately
prior to, the issue of such Common Stock or other Relevant Voting Securities,
the Parent shall purchase from the Company, and the Company shall issue and
sell to the Parent, the number of shares of Common Stock or other Relevant
Voting Security determined as provided above in Section 1(a) (or such reduced
amount as may be specified in the Parent's notice to the Company) at a price
per share determined as provided in Section 1(c) below.

         (c)(1)  In the event the Company issues Common Stock or other Relevant
Voting Securities for cash in a public offering subject to a registration
statement filed with the Securities and Exchange Commission and/or a comparable
filing with a Canadian provincial securities administration, the price at which
the Parent shall be entitled to purchase shares of Relevant Voting Securities
shall be the price at which such shares are offered to the public.





                                       3

<PAGE>   5
         (c)(2)  In the event the Company issues Relevant Voting Securities
pursuant to any transaction, contract, distribution, agreement or arrangement
(except as provided in subsection (c)(1) above), the definitive terms of which
are or have previously been publicly disclosed or announced, by press release,
communication to stockholders, Securities and Exchange Commission filings or
otherwise (the "Announcement"):

         (i)     the per share price at which the Parent shall be entitled to
         purchase shares of Common Stock pursuant to Section 1(a) shall be
         equal to the average of the closing prices for Common Stock during the
         thirty (30) day trading period commencing fifteen (15) days prior to
         the Announcement and ending fourteen (14) days after such Announcement
         (if the closing to a third party is scheduled to occur prior to the
         fifteenth trading day after the Announcement, the measuring period
         shall be the 30 trading days ending the day prior to the date of such
         closing);

         (ii)    the price at which the Parent shall be entitled to purchase
         Relevant Voting Securities other than Common Stock shall be the fair
         market value thereof as determined by reference to the current
         issuance thereof (assuming, if not the case, that such shares were
         issued in a public offering and based on an opinion of an independent
         investment banking firm or other expert retained by the Company, which
         expert shall be acceptable to the Parent in the exercise of its
         reasonable discretion).

         (c)(3)  In the event the Company issues Relevant Voting Securities
without the making of a prior Announcement relating to such issuance:

         (i)     the per share price at which the Parent shall have the right
         to purchase shares of Common Stock pursuant to Section 1(a) shall be
         equal to the average of the closing prices for Common Stock during the
         thirty (30) day trading period commencing thirty one (31) days prior
         to the date upon which the Company issues the shares of Relevant
         Voting Securities to a party other than the Parent (the "Issuance
         Date") and ending on the day prior to such Issuance Date;

         (ii)    the price at which the Parent shall be entitled to purchase
         Relevant Voting Securities other than common Stock shall be the fair
         market value thereof as determined by reference to the current
         issuance thereof (assuming, if not the case, that such shares were
         issued in a public offering and based on an opinion of an independent
         investment banking firm or other expert retained by the Company, which
         expert shall be acceptable to the Parent in the exercise of its
         reasonable discretion).

         (d)  At the closing for the purchase and sale of such Common Stock or
other Relevant Voting Security (as the case may be), the Company will deliver
to the Parent a certificate or certificates (or other appropriate evidence)
representing the securities being purchased,

registered in the name of the Parent or its designee, against payment therefore
of same day funds in an amount equal to the aggregate purchase price.  The
Parent may designate, as the purchaser on its behalf, any corporation
(excluding the Company and its subsidiaries) or other entity owned or
controlled by it (the Parent and all such corporations and other entities are
herein collectively called the "Lafarge Coppee Group").

         (e)  In the event the Company is unable to issue any Relevant Voting
Securities the Parent has the right to purchase pursuant to this Section 1
because the Company's charter does not authorize  a sufficient number of
shares, the Company shall use its best efforts to cause the stockholders of the
Company to amend the Company's charter to increase the number of authorized
shares of such Relevant Voting Securities to the number necessary to permit
such issuance and the closing of the sale of such shares of Relevant Voting
Securities to the Parent shall be postponed to a date when the Company's
charter permits such issue.

         (f)  In the event that the Parent shall be entitled to purchase
Relevant Voting Securities pursuant to this Agreement and shall have informed
the Company of its intent to make such purchase but the closing of the sale to
the Parent cannot be accomplished because of a necessity to obtain required
approvals from governmental authorities having jurisdiction over the Parent or
the Company, then such closing may be delayed at the affected party's request
for a period of up to 60 days, provided that the aggregate purchase price shall
be increased by an interest factor equal to the daily average of the publicly
announced prime commercial lending rate of Wachovia Bank of North Carolina,
N.A. in Winston Salem, North Carolina during the period.  Such interest rate
shall be calculated and certified to by the chief financial officer of the
Company or by an officer of Wachovia Bank of North Carolina, N.A.


SECTION 2.  Representations and Warranties of the Company.

         (a)  The Company is a corporation duly organized and existing in good
standing under the laws of the State of Maryland.  The Company has the
corporate power to own the property owned by it and to conduct the business

         (b)  As of the date hereof, the authorized capital stock of the
