ITEM 1.  BUSINESS.
 
THE COMPANY
 
     Lone Star is a cement, construction aggregates and ready-mixed concrete
company with operations in the midwestern, southwestern and eastern United
States. Lone Star's cement operations consist of five plants in the Midwest and
Southwest and a 25% interest in Kosmos Cement Company, a partnership which owns
and operates one cement plant in Kentucky and one in Pennsylvania ("Kosmos").
The Company's five wholly-owned cement plants produced approximately 3.8 million
tons of cement during 1995, which approximates the rated capacity of the plants.
Lone Star's construction aggregates operations consist of two quarries in New
York State. The Company's ready-mixed concrete business owns or leases and
operates several facilities in central Illinois and the Memphis, Tennessee area.
The Company had approximately $323.0 million in net sales in 1995, with cement,
construction aggregates and ready-mixed concrete operations representing
approximately 73%, 15% and 12%, respectively, of such net sales.
 
     Lone Star Industries, Inc. was incorporated in Maine in 1919 as
International Cement Corporation and, in 1936, changed its name to Lone Star
Cement Corporation. In 1969, its state of incorporation was changed to Delaware
and in 1971 its name was changed to Lone Star Industries, Inc. On April 14,
1994, the Company emerged from proceedings under Chapter 11 of the United States
Bankruptcy Code. The Company's executive offices are located at 300 First
Stamford Place, P.O. Box 120014, Stamford, Connecticut 06912-0014 and its
telephone number is (203) 969-8600. Unless the context otherwise requires, as
used herein "Company" and "Lone Star" mean Lone Star Industries, Inc. together
with its subsidiaries, excluding Rosebud Holdings, Inc. and its subsidiaries
(collectively, "Rosebud"). Rosebud is a liquidating subsidiary established in
the Company's bankruptcy proceedings.
 
CEMENT OPERATIONS
 
     Portland cement is the primary binding material used in the production of
concrete. The principal raw materials used in the manufacture of cement are
limestone or other calciferous materials, shale or clay, and sand. These raw
materials are crushed, ground, mixed together and then introduced into a rotary
kiln where they are heated to approximately 2700 degrees Fahrenheit. The
resultant marble-sized intermediate material produced by this process is known
as clinker. Clinker is then cooled, blended with a small amount of gypsum, and
ground to the consistency of face powder to produce cement.
 
     Clinker can be produced utilizing either of two basic methods, a "wet" or a
"dry" process. In the wet process, the raw materials are mixed with water to
form a slurry prior to introduction into the rotary kiln. The dry process
excludes the addition of water and dried raw materials are introduced directly
into the kiln. The wet process has the advantage of greater ease in the handling
and mixing of the raw materials, however additional heat, and therefore fuel, is
required to evaporate the moisture before the raw materials can react to form
clinker. In the dry process, which is a newer more fuel efficient technology,
hot air from the rotary kiln is recycled to pre-heat the raw materials, or
separate burners are added to accomplish a significant portion of the chemical
reaction, prior to the introduction of the raw materials into the rotary kiln.
 
     Whether a wet or dry method is utilized, the manufacture of cement is
energy intensive, and the cost of such energy accounts for approximately one
third of a cement plant's total manufacturing costs. Energy cost, and in
particular coal, varies on a regional basis due in large part to transportation
costs. In addition, the low value-to-weight ratio of cement and its constituent
raw materials results in relatively high transportation costs, creating a
largely regional business. As a result, proximity to sources of fuel and raw
materials, as well as markets, are important aspects in the profitability of a
cement plant. While subject to fluctuation and interruption resulting from
adverse weather and other factors, distribution by water is generally the least
expensive method of transporting cement.
 
     Lone Star's cement operations consist principally of the production of Type
I portland cement at the Company's five owned cement plants and the distribution
of that cement through the Company's 14 owned or leased distribution terminals.
Other products manufactured at certain of these plants include Type III portland
cement, which is a high early strength cement required in certain applications,
and specialty cements, such as masonry, oil well and slag cements. Slag cement
is a by-product of iron blast furnaces that may be used as a replacement for
portland cement in certain instances.
 
                                        1
<PAGE>   4
 
The Company also purchases cement from both domestic and international sources
for domestic resale. In addition, Lone Star owns a 25% interest in Kosmos, which
owns and operates one cement plant in Kentucky and one in Pennsylvania.
 
     All of Lone Star's five cement plants are fully integrated from limestone
mining through cement production, and the Company estimates that it has
limestone reserves sufficient to permit operation of its plants at current
levels of production for periods ranging from 30 to 100 years. Adequate supplies
of other raw materials such as gypsum, shale, clay and sand are owned, leased or
available for purchase by Lone Star. The Company believes that its plants have
adequate sources from which to purchase power and fuel.
 
     The following table sets forth certain information regarding Lone Star's
cement plants and their markets:

     Cape Girardeau Complex.  Lone Star's Cape Girardeau, Missouri plant is
located on the Mississippi River, and its related terminals are located along
the Mississippi and certain of its tributaries. Approximately 80% of the plant's
cement production is shipped up and down these rivers via 16 owned barges,
enabling the plant to serve a relatively wide market. Truck or rail are also
available to transport product. The Cape Girardeau plant includes a modern
dry/precalciner kiln and burns hazardous waste fuels. These fuels at times have
provided up to 30% of the annual energy needs of the plant and have reduced
production costs. See "Business -- Environmental Regulation". The distribution
terminals supporting the Cape Girardeau plant are located in St. Louis,
Missouri; Brandon, Mississippi; Paducah, Kentucky; Nashville and Memphis,
Tennessee; and New Orleans, Louisiana. In addition to its other customers, this
complex supplies cement to Lone Star's ready-mixed concrete operations in
Memphis, Tennessee.
 
     Greencastle Complex.  Lone Star's Greencastle plant is located
approximately 40 miles southwest of Indianapolis, Indiana and is the nearest
cement plant to this market, providing a freight cost advantage. Product is
transported by truck to Indianapolis and by truck or rail to other markets. A
portion of the Greencastle plant's production is a high quality Type III
portland cement which commands a premium price relative to Type I portland
cement, the Company's primary product. The Greencastle plant utilizes the wet
process of clinker production, however, the relative fuel inefficiency of this
process is offset in part by relatively low power and coal costs and relatively
high labor productivity at this plant. Although use of waste fuels was minimal
in 1994 and 1995, hazardous waste fuels have at times provided up to 40% of the
annual energy needs of the plant and commencing in late 1995 the plant has
resumed its use of these fuels. See "Business -- Environmental Regulation". The
Greencastle complex has distribution terminals located in Fort Wayne and
Elkhart, Indiana; and has a warehousing and distribution arrangement in Itasca,
Illinois. In addition to its other customers, this plant supplies cement to Lone
Star's ready-mixed concrete operations in central Illinois.
 
     Pryor Complex.  The Pryor plant is located approximately 50 miles northeast
of Tulsa, Oklahoma and serves the Kansas; Oklahoma; and Dallas, Texas markets by
truck and rail. A portion of the plant's product is transported by barge. This
plant produces both portland and oil well cement. The plant has relatively low
power costs due to its proximity to two low cost sources. The complex has
distribution terminals located near Wichita and Kansas City, Kansas; and in
Oklahoma
 
                                        2

City, Oklahoma; and Dallas, Texas. The Oklahoma distribution terminal's lease is
being terminated during 1996, and the Company anticipates opening a new
distribution terminal to replace it.
 
     Oglesby Complex.  The Oglesby plant is located approximately 100 miles from
Chicago and serves that and other central and northern Illinois construction
markets by truck and rail. The complex has a distribution terminal located in
Milwaukee, Wisconsin. In addition to its other customers, this plant supplies
cement to Lone Star's ready-mixed concrete operations in central Illinois.
 
     Maryneal Complex.  The Maryneal plant produces both portland and oil well
cement and serves the western Texas market by truck and rail. The complex has a
distribution terminal located in Amarillo, Texas and also shares the use of the
Dallas terminal with the Company's Pryor plant.
 
     Kosmos Cement Company.  Lone Star owns a 25% interest in Kosmos, which owns
and operates a cement plant in Kosmosdale, Kentucky and one in Pittsburgh,
Pennsylvania. Southdown, Inc., a publicly-traded cement company, owns the
remaining 75% interest and is responsible for managing the day-to-day
operations. All major decisions relating to Kosmos, however, require unanimous
approval of its management committee which includes a Lone Star representative.
 
     New Orleans Facility.  The New Orleans facility is the site of a former
cement plant that has been converted to a distribution terminal used for
receiving and storing cement from the Company's Cape Girardeau and Pryor plants
as well as from international sources. This cement is then sold directly from
the New Orleans facility or from a terminal in Brandon, Mississippi. The New
Orleans facility is located off the Gulf Intercoastal Waterway, and can
accommodate oceangoing vessels. In 1995, Lone Star also began producing slag
cement and conducting a stevedoring operation at this location.
 
CONSTRUCTION AGGREGATES OPERATIONS
 
     Lone Star, through its wholly-owned subsidiary New York Trap Rock
Corporation ("New York Trap Rock"), quarries and processes construction
aggregates, including manufactured sand, crushed stone and other stone products,
at two locations in New York State. In October 1995, another subsidiary of Lone
Star sold its assets consisting principally of a quarry and plant in Nova
Scotia. After giving effect to that sale, Lone Star's total estimated annual
production capacity is approximately 5.6 million tons and total estimated
reserves are in excess of 350 million tons. Excluding the Nova Scotia quarry,
sales volume in 1995 approximated 4.1 million tons.
 
     The following table sets forth certain information regarding Lone Star's
construction aggregates operations:

     Clinton Point Plant.  The Clinton Point plant is located on the Hudson
River near the City of Poughkeepsie, New York, approximately 65 miles from the
New York metropolitan area. The Company transports approximately 80% of this
plant's product down the Hudson River via a fleet of 117 owned barges to
customers located throughout the New York City metropolitan area. The remaining
product is delivered by truck to the local market surrounding the plant. Access
to the Hudson River enables the plant to distribute its product to a relatively
wide area. A large majority of the plant's product is sold to ready-mixed
concrete and asphalt producers, with the remainder sold for roadway projects and
specialty use such as rip rap for the construction of jetties. The Wappingers
Dolomite produced by this quarry is frequently blended with granite to meet
certain pavement skid resistance specifications, and the Company has entered
into a contract with its former Nova Scotia quarry to supply this granite until
October 1997.
 
     West Nyack Plant.  The West Nyack quarry is located in Rockland County,
northwest of New York City, and ships all of its product by truck, primarily to
counties surrounding the quarry location. The West Nyack plant currently is not
cost competitive, and the Company is reviewing options regarding this quarry and
the rest of New York Trap Rock, including the construction of a modern plant in
West Nyack, at an expected capital cost of approximately $25 million, and/or the
sale of New York Trap Rock.

READY-MIXED CONCRETE OPERATIONS
 
     Ready-mixed concrete, a versatile building material used in almost all
construction, is produced by mixing stone, sand, water and admixtures with
cement. The proximity of Lone Star's ready-mixed concrete operations to its Cape
Girardeau, Greencastle and Oglesby cement complexes have enabled them to become
vertically integrated, purchasing cement from Lone Star plants as well as
outside suppliers, and has allowed the Company to become a major supplier of
ready-mix and other concrete products in central Illinois and the Memphis,
Tennessee area. The Company sold approximately 570,000 cubic yards of
ready-mixed concrete to a variety of end users in 1995. The Company's concrete
operations include a small sand and gravel plant in central Illinois.
 
CONSTRUCTION INDUSTRY CONDITIONS
 
     The markets for the Company's products are highly competitive. Portland
cement is largely a commodity product, and due to this lack of product
differentiation, the Company competes with domestic and international sources of
cement largely on the basis of price. Accordingly, cement prices and the
Company's profitability are very sensitive to small shifts in the levels of
supply and demand in the Company's markets, and the Company's ability to compete
effectively is dependent on its operating costs being at acceptable levels. To a
lesser extent, other competitive factors such as service, delivery time and
proximity to customers affect the Company's performance.
 
     Construction spending and cement consumption historically have fluctuated
widely. Demand for cement is derived primarily from residential construction,
commercial and industrial construction and public (infrastructure) construction,
which are highly cyclical and, in turn, are influenced by prevailing economic
conditions, including interest rates and availability of public funds. Moreover,
due to cement's low value-to-weight ratio, the industry is largely regional,
with sales in a given market dependent on regional demand which is tied to local
economic factors that may fluctuate more widely than those of the United States
as a whole. In addition, the supply of cement from domestic and foreign sources
can vary from region to region and over time. As a result, even though the
Company sells in more than one area of the country, its operating results are
subject to significant fluctuation. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations". While sales by Lone Star
directly to federal, state and local governmental agencies are not significant,
customers of Lone Star are engaged in a substantial amount of construction in
which government funding is a component.
 
     According to statistics compiled by the United States Bureau of Mines, the
1980's was a period of relative high cement imports, which the Company
attributes in large part to low ocean shipping rates and excess foreign capacity
relative to demand, factors that typically affect the level of cement imports.
This high level of imports negatively affected the selling price of cement in
many regional markets, and published sources indicate that cement prices
remained in a narrow range during this period. As a result of anti-dumping
petitions filed by a group of domestic cement producers beginning in 1990,
anti-dumping orders were imposed on cement imported from Mexico and Japan. The
resulting anti-dumping duties are being determined in annual administrative
reviews by the United States Department of Commerce. Notwithstanding recent
amendments to the anti-dumping provisions enacted as a result of the Uruguay
round of world trade negotiations under the General Agreement on Tariffs and
Trade ("GATT") and significant lobbying and litigation by Mexican cement
producers, which are ongoing, the Company believes that the U.S. anti-dumping
law currently provides effective remedies against unfairly priced imports. In
particular, the anti-dumping orders against Mexico and Japan are scheduled to
remain in effect until January 1, 2000 and may continue thereafter if
petitioners prevail in "sunset reviews" before the Commerce Department and the
U.S. International Trade Commission. Recent improvement in the performance of
the United States economy, coupled with lower imports, has led to a more
favorable supply/demand ratio for cement suppliers, which enabled the Company to
implement price increases in both 1994 and 1995. The Company has announced
cement price increases of $3 to $5 per ton effective April 1996.
 
     According to published sources, the United States cement industry is
comprised of approximately 50 companies with an annual cement production
capacity in the 85 to 87.5 million ton range. The ten largest companies account
for approximately 60% of the total productive capacity. While modest increases
in the production capacity of the industry have been accomplished through
modifications to existing facilities, and competitors of Lone Star's have
announced plans to make capital expenditures to expand and modernize certain
existing facilities and, in one case, build a new "greenfield" cement plant, the
high cost of new plants and the requisite lengthy permitting process are
significant barriers to new
 
                                        4
<PAGE>   7
 
domestic production capacity. Imported cement has traditionally filled the gap
during periods where the demand for cement was high relative to domestic
productive capacity.
 
     Construction spending and cement consumption are seasonal, particularly in
the Company's northern markets where colder weather affects construction
activity. Other adverse weather conditions such as flooding, which can interrupt
production and transportation of cement, and extreme heat, which can affect
concrete pouring, also affect the Company's operations.
 
CUSTOMERS AND MARKETING; BACKLOG
 
     The Company's customer base primarily consists of ready-mixed concrete
producers, prestressed concrete producers, other concrete product producers and
highway construction firms. Taken as a whole, no single customer of the Company
accounted for more than 10% of total sales during 1995. The marketing effort for
the Company's cement, construction aggregates and ready-mixed concrete
operations is handled by a local sales force. Most purchases of the Company's
products are done on a spot basis, and accordingly, order backlogs are not
significant.
 
ENVIRONMENTAL REGULATION
 
     The Company, like others in the construction materials and cement
manufacturing industry, is subject to extensive, stringent and complex federal,
state and local laws, regulations and ordinances pertaining to the quality and
the protection of the environment (including those governing water discharges,
air emissions and the handling, use and disposal of hazardous and non-hazardous
waste materials) and human health and safety, requiring the Company to devote
substantial time and resources in an effort to maintain continued compliance.
Many of the laws and regulations apply to the Company's former activities,
properties and facilities as well as its current operations. Changes to such
regulations or the enactment of new regulations in the future could require the
Company to undertake capital improvement projects or to cease or curtail certain
current operations or could otherwise substantially increase the capital,
operating and other costs associated with compliance. Moreover, there can be no
assurances that judicial or administrative proceedings, seeking penalties or
injunctive relief, will not be brought against the Company for alleged
non-compliance with applicable environmental laws and regulations relating to
matters as to which the Company is currently unaware. In addition, if releases
of hazardous substances are discovered to have occurred at facilities currently
or previously owned or operated by the Company, or at facilities to which the
Company has sent waste materials, the Company may be subject to liability for
the investigation and remediation of such sites.
 
     The federal Water Pollution Control Act, commonly known as the Clean Water
Act, provides a comprehensive federal regulatory scheme governing the discharge
of pollutants to waters of the United States. This regulatory scheme requires
that permits be secured for discharges of wastewater, including stormwater
runoff associated with industrial activity, to waters of the United States. The
Company has secured or has applied for all required permits in connection with
its wastewater and stormwater discharges.
 
     The Clean Air Act was amended in 1990 to provide for a uniform federal
regulatory scheme governing control of air pollutant emissions and permit
requirements. In addition, certain states in which the Company operates have
enacted laws and regulations governing the emission of air pollutants and
requiring permits for sources of air pollutants. As a result of the 1990
amendments to the Clean Air Act, the Company is required to apply for federal
operating permits for each of its cement manufacturing facilities at various
dates ranging from 1996 through 1999. As part of the permitting process, the
Company may be required to install equipment to monitor emissions of air
pollutants from its facilities. In addition, the Clean Air Act amendments
require the United States Environmental Protection Agency ("EPA") to develop
regulations directed at reducing emissions of toxic air pollutants from a
variety of industrial sources, including the portland cement manufacturing
industry. As part of this process, the EPA will identify maximum available
control technology ("MACT") for the reduction of emissions of air toxins from
cement manufacturing facilities. Following the EPA's promulgations of MACT for
the cement industry, the Company, like others in the industry, may be required
to install additional control technology at its cement manufacturing facilities
and meet more stringent air emissions standards. On March 20, 1996, the EPA
announced proposed separate, more stringent MACT standards for those cement
manufacturing facilities (like Lone Star's Greencastle and Cape Girardeau
plants) that burn hazardous waste fuels ("HWF"). These standards, which are
subject to public comment and are not anticipated by the Company to be in full
force and effect prior to the end of 1996, are extremely lengthy and complex and
have not been reviewed by the Company, but depending on their terms could have
the effect of limiting or eliminating the use of HWF at one or both facilities.
 
                                        5
<PAGE>   8
 
     The Resource Conservation and Recovery Act ("RCRA") establishes a
cradle-to-grave regulatory scheme governing the generation, treatment, storage,
handling, transportation and disposal of solid wastes. Solid wastes which are
classified as hazardous wastes pursuant to RCRA, as well as facilities that
treat, store or dispose of such hazardous wastes, are subject to stringent
regulatory requirements. Generally, wastes produced by the Company's operations
are not classified as hazardous wastes and are subject to less stringent federal
and state regulatory requirements. Cement kiln dust ("CKD"), a by-product of
cement manufacturing, is currently exempted from regulation as a hazardous waste
pursuant to the Bevill Amendment to RCRA. However, on January 31, 1995 the EPA
issued a regulatory determination regarding the need for regulatory controls on
the management, handling and disposal of CKD. Generally, the EPA regulatory
determination provides that the EPA intends to draft and promulgate regulations
imposing controls on the management, handling and disposal of CKD that will be
based largely on selected components of the existing RCRA hazardous waste
regulatory program, tailored to address the specific regulatory concerns posed
by CKD. The EPA regulatory determination further provides that new CKD
regulations will be designed both to be protective of the environment and to
minimize the burden on cement manufacturers. In early 1996, EPA officials
reported that certain other alternatives -- such as oversight of CKD management
by state environmental agencies -- also are being explored. It is not possible
to predict at this time what, if any, new regulatory controls on the management,
handling and disposal of CKD or what increased costs (or range of costs), if
any, would be incurred by the Company to comply with these requirements. As an
alternative to new EPA regulations or state oversight, portland cement
manufacturers, including Lone Star, are engaged in negotiations with the EPA in
an attempt to enter into other arrangements relating to the management of CKD.
 
     On July 20, 1995, the State of Indiana made a determination that the CKD
stored at the Company's Greencastle plant is a type I waste and requested that
the Company apply for a formal permit for an on-site landfill for the CKD. The
Company understands that similar notices were sent to other cement manufacturers
in the State of Indiana. The Company is protesting this determination through
legal channels and has received a stay to allow it to demonstrate that current
management practices pose no threat to the environment. The Company believes
that the State's determination ultimately will be reversed or the Company will
receive the needed permit or other adequate relief, such as an agreed order
requiring certain additional waste management procedures that are less stringent
than those required for type I wastes. If the Company is not successful in this
regard, however, like other Indiana cement producers, the Greencastle plant
could incur substantially increased operating and capital costs.
 
     The Cape Girardeau, Missouri and Greencastle, Indiana plants, which are the
Company's two cement manufacturing facilities using HWF as a cost-saving energy
source, are subject to strict federal, state and local requirements governing
hazardous waste treatment, storage and disposal facilities, including those
contained in the federal Boiler and Industrial Furnace Regulations promulgated
under RCRA (the "BIF Rules"). These facilities qualified for and operate under
interim status pursuant to RCRA and the BIF Rules. While Lone Star believes that
it is currently in compliance with the extensive and complex technical
requirements of the BIF Rules, in the past Lone Star has been involved in
certain environmental enforcement proceedings seeking civil penalties and
injunctive relief for past non-compliance, and there can be no assurances that
the Company will be able to maintain compliance with the BIF Rules or that
changes to such rules or their interpretation by the relevant agencies or courts
might not make it more difficult or cost prohibitive to continue to burn HWF. As
a result of a court decision vacating a BIF Rules air emission standard, the
Company temporarily curtailed its use of HWF at the Greencastle cement plant.
The Company completed compliance testing in August 1995, has recertified under
interim status and has recommenced burning HWF.
 
     The Company is currently engaged in the process of securing the permit
required under RCRA and the BIF Rules for the Cape Girardeau plant. The Company
anticipates that the Greencastle plant also will go through this permitting
process in late 1996. These permits are a requirement to enable Lone Star to
continue the use of HWF at those facilities. The permitting process is lengthy
and complex, involving the submission of extensive technical data. There can be
no assurances that the Company will be successful in securing a final RCRA
permit for either or both of its HWF facilities. In addition, if received, the
permits could contain terms and conditions with which the Company cannot comply
or could require the Company to install and operate costly control technology
equipment.
 
     The federal Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA" or "Superfund"), as well as many comparable state
statutes, creates a joint and several liability scheme for the investigation and
remediation of facilities where releases of hazardous substances are found to
have occurred. Liability may be imposed upon current owners and operators of the
facility, upon owners and operators of the facility at the time of the release
and upon generators and transporters of hazardous substances released at the
facility. While, as noted above, wastes produced
 
                                        6
<PAGE>   9
 
by the Company generally are not classified as hazardous wastes, many of the raw
materials, by-products and wastes currently and previously produced, used or
disposed of by the Company or its predecessors contain chemical elements or
components that have been designated as hazardous substances or which otherwise
may cause environmental contamination. Hazardous substances are or have been
used or produced by the Company in connection with its cement manufacturing
operations (e.g. grinding compounds, refractory bricks), quarrying operations
(e.g. blasting materials), equipment operation and maintenance (e.g. lubricants,
solvents, grinding aids, cleaning aids, used oils), and hazardous waste fuel
burning operations. CKD and other materials were placed in depleted quarries and
other locations for many years. The Company has been named by the EPA as a
potentially responsible party for the investigation and remediation of several
Superfund sites. In certain circumstances the Company is undertaking
investigation and remediation pursuant to state environmental requirements. See
Note 27 of Notes to Consolidated Financial Statements. In addition, the Company
is reviewing certain of its inactive properties to determine if any remedial
action may be required at these sites. There can be no assurances that the
Company will not have additional liability as a result of its being named as a
potentially responsible party at additional Superfund sites or that additional
releases of hazardous substances will not be found to have occurred at
facilities presently or formerly owned or operated by the Company. Although the
Company may be able to avoid the imposition of such liability for releases or
threatened releases of hazardous substances that occurred prior to the
commencement of the Company's bankruptcy proceedings in 1990, there can be no
assurances in this regard.
 
     The Company's operations are also subject to federal and state laws and
regulations designed to protect worker health and safety. Worker protection at
the Company's cement manufacturing and construction aggregates facilities is
governed by the federal Mine Safety and Health Act ("MSHA") and at other Company
operations is governed by the federal Occupational Safety and Health Act
("OSHA").
 
     For additional information concerning certain environmental matters
involving the Company, see Note 27 of Notes to Consolidated Financial
Statements.
 
EMPLOYEES
 
     As of December 31, 1995, the Company had approximately 1,450 employees. Of
these employees, approximately 950, including all hourly employees at all
Company operations other than certain cement distribution terminals and the New
Orleans slag cement and stevedoring operations, were members of labor unions.
During 1995, there were no labor disruptions at any of the Company's facilities.
The Company believes that relations with its employees generally have been good.
 
     A number of collective bargaining agreements covering Lone Star's hourly
employees at its ready-mixed concrete operations were renegotiated in 1995.
During 1996, collective bargaining agreements covering substantially all Lone
Star's hourly employees at its cement and construction aggregates operations
will be renegotiated. The Company does not currently anticipate any unusual
circumstances or difficulties in obtaining replacement agreements, however,
there can be no assurances in this regard.
 
BANKRUPTCY REORGANIZATION PROCEEDINGS AND LIQUIDATING SUBSIDIARY
 
     In December 1990, Lone Star Industries, Inc. and certain of its
subsidiaries commenced proceedings under Chapter 11 of the Federal Bankruptcy
Code. The Chapter 11 proceedings were precipitated by a variety of factors
including generally depressed economic and business conditions, increasingly
restricted sources of financing, potential defaults under long-term debt
agreements, potential litigation exposure relating to concrete railroad
crossties, and uncertainty and potential liabilities with respect to
environmental, retiree benefit and pension related obligations. The Chapter 11
proceedings were commenced in order to preserve the Company's assets and enable
it to seek a long-term solution to its financial, litigation and business
problems.
 
     On April 14, 1994, the Company emerged from its Chapter 11 proceedings
pursuant to a plan of reorganization. Upon emergence from the Chapter 11
proceedings, the Company was reorganized around its core domestic operations,
and Rosebud was formed to own and liquidate remaining non-core assets and
operations (the "Rosebud Assets"). Pursuant to its plan of reorganization, Lone
Star issued certain equity securities in exchange for pre-petition equity and
paid cash and issued debt and equity securities for certain pre-petition debt
and other claims. Certain other pre-petition indebtedness was discharged,
reinstated or restructured and assumed; certain litigations were settled; and a
restructured
 
                                        7
<PAGE>   10
 
Board of Directors was designated. The plan of reorganization also implemented
settlements relating to certain retiree health and life insurance benefits,
pension and financing obligations.
 
     As part of a pre-petition restructuring which commenced in 1989 and
continued through the Chapter 11 proceedings, the Company implemented a
comprehensive organizational and financial restructuring through which it closed
certain facilities, reduced management, strategically disposed of assets
(including substantially all its partnership, joint venture and foreign
interests), rejected or modified agreements, and improved operating procedures
at its ongoing operations. Certain assets that had been held for sale under the
1989 restructuring program were included as part of the reorganized entity and
other such assets were included in the Rosebud Assets. In addition, the Company
adopted fresh-start reporting. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and Note 23 of Notes to
Consolidated Financial Statements.
 
     Rosebud was established for the purpose of liquidating the Rosebud Assets
for the benefit of holders of Rosebud's 10% Asset Proceeds Notes due 1997 issued
pursuant to the Company's Plan of Reorganization ("Asset Proceeds Notes"). As of
February 29, 1996, there remained outstanding an aggregate $4.4 million
principal amount of Asset Proceeds Notes, for which Lone Star has no liability.
Rosebud Assets remaining at February 29, 1996 consist of certain unimproved
property located in Louisiana, Massachusetts, Oregon, Texas and Virginia, net
available cash in the amount of approximately $2.4 million, and a secured
promissory note in the principal amount of $0.3 million.
 
     Liabilities associated with all Rosebud Assets, sold and unsold, were
assumed by Rosebud and it has agreed to indemnify Lone Star for these
liabilities. However, the assumption of Lone Star's liabilities by Rosebud may
not be binding upon third parties, and, in any event, as to any such liabilities
arising from actions or circumstances that existed on or before April 14, 1994
and that result in payments to Lone Star aggregating in excess of $7.0 million,
Rosebud's obligation to indemnify Lone Star in respect thereof is subordinated
to repayment of the Asset Proceeds Notes. Lone Star provides management and
various other services to Rosebud pursuant to a Management Services Agreement
under which Rosebud pays to Lone Star a quarterly fee of 0.25% of the value of
its unsold assets and reimburses Lone Star for any payment Lone Star makes to
third parties on behalf of Rosebud, subject to the limitations described above.
Rosebud paid Lone Star a fee of $0.6 million for services rendered during 1995.
 
ITEM 2.  PROPERTIES.
 
     Lone Star's main operations are conducted at its plants and distribution
terminals described in Item 1 above. Lone Star owns its five cement plants and a
majority of the distribution terminals supporting these plants. With respect to
those distribution terminals not owned, Lone Star holds a land lease for the
underlying real property and owns the facilities located on such property. There
is one additional distribution terminal that is leased to a third party. Lone
Star owns its aggregate operations except for a small sand and gravel quarry
associated with the Company's concrete operations, which is leased. The
ready-mixed concrete plants are located on owned land or sites held under leases
for varying terms. No difficulty is anticipated in renewing leases as they
expire or finding satisfactory alternative sites. The Company leases executive
offices in Stamford, Connecticut and owns or leases offices in Indianapolis,
Indiana and West Nyack, New York. The Company also owns or leases other offices
in the United States.
 
ITEM 3.  LEGAL PROCEEDINGS.
 
     From time to time the Company is named as a defendant in lawsuits asserting
product liability for which the Company maintains insurance coverage. In late
1995, an office building in Boston, Massachusetts, constructed in 1983 using
concrete pilings produced by San-Vel Concrete Corporation, an inactive Lone Star
subsidiary ("San-Vel"), was demolished by order of the City of Boston based upon
an engineering report that the pilings were unreliable. The owner of the
building has notified the Company, among others, that it intends to hold
responsible parties liable. At the request of the City of Boston, San-Vel has
provided a list of the approximate twenty-five other buildings built in that
City between 1980 and 1990 using San-Vel pilings. The City has reportedly
inspected these buildings visually, without noting any apparent piling failure,
although engineering studies are reportedly being conducted with final results
expected in mid-1996. The Company believes that the cement component of the
concrete used to produce the pilings in certain of these buildings, including
the demolished building, was produced by it at one of its former cement plants.
There has been no indication that the cement was defective. The Company is
conducting an investigation into these matters and believes that it has both
insurance coverage and good defenses to any claim of liability that may be
asserted against it relating to the demolished building.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
        FINANCIAL CONDITION AND RESULTS OF OPERATIONS.
 
FINANCIAL CONDITION
 
     As of March 31, 1994, in accordance with AICPA Statement of Position No.
90-7, "Financial Reporting by Entities in Reorganization Under the Bankruptcy
Code" the Company adopted fresh-start reporting which included adjustments for
bankruptcy-related cash transactions through the effective date, which for
accounting purposes was March 31, 1994, to properly reflect the reorganization.
As a result of the plan of reorganization becoming effective, the Company's
financial statements for the year ended December 31, 1995 are not comparable to
statements for the prior year. (See Note 24 for 1994 pro forma results.)
 
     In accordance with the plan of reorganization which became effective on
April 14, 1994, the Company issued senior notes in the aggregate principal
amount of $78.0 million, 12 million shares of common stock and 4 million
warrants to purchase common stock. The senior notes bear interest at a rate of
10% per annum, payable semi-annually, and mature on July 31, 2003. The warrants
are exercisable through December 31, 2000 and each warrant provides for the
purchase of one share of common stock at a price of $18.75 per share. Both
preferred stock issues and the predecessor company's common stock were canceled
on the plan effective date.
 
     In addition, as discussed in Note 8, the asset proceeds notes issued by
Rosebud Holdings, Inc., the Company's liquidating subsidiary, bear interest at a
rate of 10% per annum payable in cash and/or in additional asset proceeds notes
in semi-annual installments.
 
     The asset proceeds notes mature on July 31, 1997. These notes were
guaranteed, in part, by the Company pursuant to the Company guarantee. The
Company's guarantee, guarantee agreement, and the related pledge of Rosebud's
common stock owned by the Company was terminated on July 14, 1995 as the
combined partial redemption of the asset proceeds notes made to that date
exceeded $88.1 million. As of December 31, 1995, total interest and principal
payments of approximately $150.5 million had been paid on the asset proceeds
notes.
 
     The remaining face value of the asset proceeds notes as of December 31,
1995 was $4.4 million. Other than an initial $5.0 million cash contribution by
the Company for working capital purposes, the Company is not obligated to fund
additional Rosebud working capital requirements. Cash generated by Rosebud in
excess of the remaining face value of the asset proceeds notes, accrued interest
and Rosebud working capital requirements, if any, will be paid to Lone Star.
 
     Upon emergence from Chapter 11 the Company entered into a three-year, $35.0
million revolving credit agreement, which is collateralized by inventory,
receivables, collection proceeds and certain intangible assets. The agreement
was subsequently amended in April, November and December 1995. The amendments
reduced the rates of interest under the agreement and increased the amounts
allowed for capital expenditures and certain other payments. Although the
Company from time to time has used the letter of credit facility provided by the
credit agreement, it has not drawn any funds under the credit agreement for
working capital purposes. Accordingly, there was no outstanding balance at
December 31, 1995.
 
     In November 1995, the Board of Directors authorized the expenditure of up
to $20.0 million for the repurchase of the Company's common stock. The Company
executed a purchase of 600,000 shares through a privately negotiated transaction
in mid-November 1995 at a cost of $13.9 million.
 
     During 1995, the Company made scheduled payments of $3.0 million and a
prepayment of $17.0 million, terminating the production payment liability.
 
     The Company's financing agreements contain restrictive covenants which,
among other things, limit the payment of dividends, and prohibit or limit the
Company's ability to incur additional indebtedness, create liens, engage in
mergers and acquisitions or make certain capital expenditures.
 
Analysis of Cash Flows and Working Capital
 
     Cash flows from operating activities of $50.3 million for the year ended
December 31, 1995, primarily reflect income from operations, changes in working
capital and $11.3 million of pension plan contributions. The utilization of net
operating loss carryforwards in 1995 will reduce cash taxes otherwise payable by
approximately $15.8 million. At
 
                                       11
<PAGE>   14
 
December 31, 1995 the Company had net operating loss carryforwards of
approximately $200.0 million which are expected to reduce future cash taxes by
an additional $70.0 million over time.
 
     During the year ended December 31, 1995, the Company used $21.2 million for
investing activities, primarily representing capital expenditures, partly offset
by proceeds of $15.4 million from asset sales, including the Nova Scotia, Canada
aggregate operation, and the Denver, Colorado concrete railroad tie plant, which
had been leased to a third party.
 
     Net cash outflows from financing activities of $34.5 million for the year
ended December 31, 1995 primarily reflect payments on the remaining production
payment balance of $20.0 million and the repurchase of 600,000 shares of the
Company's common stock for $13.9 million.
 
     Working capital on December 31, 1995, was $81.7 million as compared to
$71.4 million on December 31, 1994. Current assets increased $5.6 million
primarily due to higher inventory and prepaid expenses, partly offset by lower
marketable securities. Current liabilities decreased $4.7 million primarily due
to a $3.0 million reduction on the production payment and lower accounts
payable, partly offset by higher state taxes payable.
 
     Investments in joint ventures increased $3.0 million due to income from
Kosmos Cement Company, less cash dividends paid. Net property, plant and
equipment increased $1.4 million reflecting capital expenditures partly offset
by depreciation and the sales of the Nova Scotia quarry and the Denver facility.
Payments of $17.0 million on the long-term portion of the production payment
terminated the liability. The long-term pension liability decreased $7.5
million, primarily reflecting contributions made during 1995 in excess of
current expenses.
 
     The carrying value on the Company's books of net assets of Rosebud and the
related asset proceeds notes decreased $82.6 million primarily due to a $30.0
million redemption of the outstanding notes in late February 1995, a $25.0
million redemption in July 1995, a $12.0 million redemption in October 1995 and
a $35.0 million redemption in December 1995 which primarily resulted from asset
sales and recoveries. This was partly offset by an increase in asset valuation
reflecting the shorter time period used in determining the present value. The
decrease was also partly offset by a $9.4 million net proceeds recovery from the
crosstie litigation involving Northeast Cement Company and its affiliates,
Lafarge Corporation and Lafarge Canada, Inc., and by the inclusion of litigation
settlements totaling $6.7 million reached with the remaining insurance companies
related to indemnity in the crosstie cases and with two Argentine companies
related to the 1992 auction sale of the Company's Argentine subsidiary. Prior to
reaching final agreements, these recoveries were not included in the valuation
of the net assets of Rosebud. All payments related to the above litigation
settlements have been received.
 
Capital Expenditures
 
     Capital expenditures of $36.6 million for 1995 were primarily for major
repairs, replacements and improvements at existing facilities, including the
expansion of the St. Louis, Missouri cement terminal to be completed in 1996.
Capital expenditures also included $5.8 million related to the purchase of a
fleet of barges used by New York Trap Rock, which had previously been leased.
 
     In an effort to increase production, improve operating efficiencies and
reduce costs, the Company expects to make capital investments of approximately
$50.0 million in 1996. In addition to spending $8.9 million for a modern clinker
storage facility at the Cape Girardeau cement plant expected to be completed in
early 1997, the Company intends to make various other improvements at its Cape
Girardeau complex at an expected cost of approximately $5.7 million. Planned
expenditures for 1996 also include improvements to the New Orleans, Louisiana
cement terminal and slag grinding facility at a cost of approximately $5.6
million and improvements, including the expansion of two cement terminals and
the relocation of another cement terminal, at an expected cost of $7.5 million.
The Company expects to fund its 1996 capital expenditures from cash on hand in
addition to cash to be generated from operations.
 
Other Information
 
     The Company is subject to extensive, stringent and complex federal, state
and local laws, regulations and ordinances pertaining to the quality and the
protection of the environment and human health and safety, requiring the Company
to devote substantial time and resources in an effort to maintain continued
compliance. Many of the laws and regulations apply to the Company's former
activities, properties and facilities as well as its current operations. Changes
to such regulations or the enactment of new regulations in the future could
require the Company to undertake capital improvement projects or to cease or
curtail certain current operations or could otherwise substantially increase the
capital,
 
                                       12
<PAGE>   15
 
operating and other costs associated with compliance. Moreover, there can be no
assurances that judicial or administrative proceedings, seeking penalties or
injunctive relief, will not be brought against the Company for alleged
non-compliance with applicable environmental laws and regulations relating to
matters as to which the Company is currently unaware. In addition, if releases
of hazardous substances are discovered to have occurred at facilities currently
or previously owned or operated by the Company, or at facilities to which the
Company has sent waste materials, the Company may be subject to liability for
the investigation and remediation of such sites.
 
     The Company believes that it has adequately provided for costs related to
its ongoing obligations with respect to known environmental liabilities.
Expenditures for environmental liabilities during 1995 did not have a material
effect on the financial condition or cash flows of the Company. The December 31,
1995 accompanying consolidated balance sheet includes accruals of $6.9 million
which represent the Company's current estimate of its liability related to
environmental matters.
 
     On January 31, 1995, the United States Environmental Protection Agency
("EPA") issued a regulatory determination regarding the need for regulatory
controls on the management, handling and disposal of cement kiln dust ("CKD"), a
by-product of cement manufacturing. Generally, the regulatory determination
provides that the EPA intends to draft and promulgate regulations imposing
controls on the management, handling and disposal of CKD that will be based
largely on selected components of the existing Resource Conservation and
Recovery Act ("RCRA") hazardous waste regulatory program, tailored to address
the specific regulatory concerns posed by CKD. The EPA regulatory determination
further provides that new CKD regulations will be designed both to be protective
of the environment and to minimize the burden on cement manufacturers. In early
1996, EPA officials reported that certain other alternatives -- such as
oversight of CKD management by state officials -- also are being explored. It is
not possible to predict at this time what, if any, new regulatory controls on
the management, handling and disposal of CKD or what increased costs (or range
of costs), if any, would be incurred by the Company to comply with these
regulatory requirements. As an alternative to new EPA regulations or state
oversight, portland cement manufacturers including Lone Star, are engaged in
negotiations with the EPA in an attempt to enter into other arrangements
relating to the management of CKD.
 
     On July 20, 1995, the State of Indiana made a determination that the
Company's CKD was a type I waste and requested that the Company apply for a
formal permit for an on-site landfill for the CKD at the Greencastle, Indiana
plant. The Company understands that similar notices were sent to all other
cement manufacturers in the State of Indiana. The Company is protesting this
determination through legal channels and received a stay to allow it to
demonstrate that current management practices pose no threat to the environment.
The Company believes that the State's determination ultimately will be reversed
or the Company will receive the needed permit or other adequate relief such as
an agreed order requiring certain additional waste management procedures that
are less stringent than those required for type I wastes. If the Company is not
successful in this regard, however, like other Indiana cement producers, the
Greencastle plant could incur substantially increased operating costs.
 
     A number of collective bargaining agreements covering the Company's hourly
employees at its ready-mixed concrete operations were renegotiated in 1995.
During 1996 collective bargaining agreements covering substantially all of the
Company's hourly employees at its cement and construction aggregates operations
will be renegotiated. The Company does not currently anticipate any unusual
circumstances or difficulties in obtaining replacement agreements.
 
DIVIDENDS AND STOCK MARKET PRICES
 
     In April 1995 the Company's Board of Directors declared a $0.05 per share
dividend paid on June 15, 1995 to shareholders of record as of June 1, 1995 and
announced their intention to continue, so long as merited, this dividend on a
quarterly basis. The dividend represented the first cash dividend paid since
1989. The Board of Directors has since declared additional $0.05 per share
dividends paid on September 15, 1995 and December 15, 1995. On February 1, 1996
the Board of Directors declared a $0.05 per share dividend payable on March 15,
1996 to stockholders of record as of March 1, 1996.
 
     The common stock, warrants and senior notes are listed on the New York
Stock Exchange ("NYSE") and began trading May 3, 1994 (Prior to this the old
common stock and preferred stock traded on the NYSE). The following table sets
forth the high and low sales prices for the common stock and warrants in
composite transactions as reported on the NYSE.

     On March 15, 1996, the reported sale price of the common stock and warrants
was $29 1/4 per share and $13 1/4 per warrant, respectively. As of March 15,
1996, the Company had approximately 1,925 holders of record of common stock and
2,874 holders of record of warrants.
 
RESULTS OF OPERATIONS
 
     On April 14, 1994 the plan of reorganization became effective. Upon the
plan of reorganization becoming effective, the Company issued new common stock,
warrants, senior notes and asset proceeds notes, transferred certain assets to
Rosebud and for accounting purposes adopted fresh-start reporting as of March
31, 1994. As a result, the Company's financial statements for the year ended
December 31, 1995 are not comparable to statements for prior periods. Also
affecting comparability are differences in the operating units of the successor
company and the predecessor company. The successor company's operations include
the Pryor, Oklahoma and Maryneal, Texas cement plants which were previously
classified as assets held for sale and were excluded from the predecessor
company's results. The successor company's operations exclude the Nazareth,
Pennsylvania and Santa Cruz, California cement plants and the Hawaiian Cement
and RMC LONESTAR partnerships. These operations, along with certain other
assets, were transferred to Rosebud. See Note 1 for a description of operations
and basis of presentation.
 
     To facilitate a meaningful comparison of the Company's operating
performance, as historical annual results for 1995 and 1994 are not comparable,
the following discussion and analysis compares the results of the historical
year ended December 31, 1995 with the pro forma results for the 1994 period (See
Note 24). The Company believes that this comparison is useful in understanding
its operating performance for the current year.
 
     The Company's operations are seasonal and, consequently, the interim
results are not necessarily indicative of the results to be expected for the
full year.
 
1995 COMPARED TO PRO FORMA 1994
 
Net Sales
 
     Consolidated net sales of $323.0 million during 1995 were $16.1 million
higher than the prior year pro forma results. The increase in net sales
primarily reflects cement price increases implemented in April 1995 and during
1994. Cement price increases of $3 to $5 per ton have been announced effective
April 1996.
 
     Cement sales of $237.4 million during 1995 were $24.2 million greater than
the prior year pro forma results, primarily due to 15% higher average cement net
realized selling prices in 1995, the result of price increases which began in
1994. Cement shipments for 1995 were 4% below 1994 levels.
 
     Sales of construction aggregates of $48.4 million during 1995 were $1.8
million lower than the 1994 pro forma results. This decrease is primarily
attributable to lower shipments, particularly into the New York Metropolitan
area, resulting from soft market conditions. The 9% decrease in overall
construction aggregates' shipments was partly offset by a 5% increase in average
selling prices.
 
     Ready-mixed concrete and other operations sales during 1995 were $37.3
million, $6.3 million below the prior year pro forma results. This reflects a
21% decrease in shipments resulting from unfavorable weather conditions
experienced
 
                                       14
<PAGE>   17
 
during the second and third quarters of 1995 in the Midwest, combined with soft
market conditions. The decrease in shipments was partly offset by a 12% increase
in average net realized selling prices.
 
     Net sales of cement, construction aggregates and ready mixed concrete and
other products contributed 73%, 15% and 12%, respectively, to total sales for
1995.
 
Gross Profits
 
     Gross profits from the cement operations were $72.7 million in 1995 as
compared to pro forma gross profits of $52.7 million for 1994. Gross profits at
each plant in 1995 were higher than the previous year. These results primarily
reflect 15% higher average cement net realized selling prices in 1995. Partly
offsetting these favorable results were higher overall per unit costs,
reflecting higher costs and production interruptions, particularly at the
Maryneal, Texas cement plant.
 
     The Cape Girardeau, Missouri and Greencastle cement plants use hazardous
waste fuel as cost-saving energy sources. The Company expects to continue to
operate its waste fuel program which is subject to stringent regulation pursuant
to federal, state and local requirements governing hazardous waste treatment,
storage and disposal facilities. There can be no assurance that the Company's
hazardous waste fuel operations will be able to maintain compliance with the
requirements contained in the federal Boiler and Industrial Furnace Regulations
under RCRA ("BIF Rules") and state requirements or that changes to such rules or
requirements or their interpretation by the relevant agencies or courts will not
make it more difficult or cost prohibitive to maintain regulatory compliance or
to continue to burn hazardous waste fuel (See Note 27).
 
     Construction aggregates gross profits of $3.5 million during 1995 increased
$1.1 million over the prior year pro forma results. These results primarily
reflect lower finance costs associated with the purchase of the fleet of barges
which had previously been leased, along with a 5% increase in overall average
selling prices, partly offset by lower shipments in 1995 in the New York
Metropolitan area due to soft market conditions. Shipments from the New York
Trap Rock operations were adversely affected by the temporary closure of a
customer's asphalt plant (for rebuilding purposes), a sluggish concrete stone
market, and the decision not to compete on certain low price jobs. Lower per
unit production costs associated with higher production volume efficiencies at
the Nova Scotia, Canada operation contributed to the improved results. The
assets of the Nova Scotia quarry were sold in October 1995 for net proceeds
including working capital of about $11.4 million, which approximated book value.
This operation contributed sales of $8.1 million and an operating loss of $0.4
million to the 1995 results.
 
     Gross profits from ready-mixed concrete and other construction products
were $5.7 million for 1995, a $0.1 million decrease from the 1994 pro forma
results, primarily reflecting a 21% decrease in overall ready-mixed concrete
shipments, partly offset by a 12% increase in overall average net realized
selling prices. Lower ready-mixed concrete and concrete block shipments resulted
from unfavorable weather in the Midwest and soft market conditions, particularly
in the central Illinois area. Higher per unit costs at all operations adversely
affected 1995 gross profits.
 
     Included in the calculation of gross profits are sales less cost of sales
including depreciation related to cost of sales (which excludes depreciation
related to facilities leased to third parties and depreciation on office
equipment, furniture and fixtures which are not related to the cost of sales).
 
Joint Ventures
 
     Pre-tax income from joint ventures of $6.7 million during 1995 reflects the
results of the Kosmos Cement Company, a partnership in which the Company has a
25% interest. The results for 1995 were $2.1 million higher than the prior year
reflecting higher net realized selling prices, partly offset by lower shipments.
 
Other Income
 
     Other income of $4.0 million in 1995 decreased $1.0 million from 1994,
reflecting lower rental income resulting from sales of assets which had been
leased to third parties partly offset by proceeds from an insurance settlement
relating to a prior year claim.
 
                                       15
<PAGE>   18
 
Selling, General and Administrative Expenses
 
     Selling, general and administrative expenses of $29.7 million during 1995
represent a decrease of $2.4 million over the prior-year pro forma expense. The
savings in selling, general and administrative expenses primarily reflect lower
corporate headquarters expenses and lower other postretirement benefit expenses
in 1995. The savings in corporate headquarters expenses reflect a corporate
downsizing which occurred on June 30, 1994, which eliminated approximately 35%
of the salaried positions at the corporate office. The lower other
postretirement benefits were the result of favorable experience for retiree
medical claims. Selling, general and administrative expenses for 1995 include
$5.7 million of other postretirement benefit costs related to the Company's
presently retired employees. Selling, general and administrative expenses for
1994 included $0.5 million relating to the filing of a registration statement.
 
Interest Expense
 
     Interest expense of $9.1 million in 1995 approximated the prior year pro
forma total. Capitalized interest was $0.3 million in 1995. Interest expense was
comprised primarily of interest accrued on the $78.0 million 10% senior notes
and the Company's obligation related to the production payment.
 
Income Taxes
 
     The income tax expense of $17.6 million during 1995, an increase of $5.6
million from the prior year pro forma expense, primarily reflects higher taxes
resulting from higher pre-tax earnings in 1995. The provision for income taxes
for 1995 reflects a 33% effective tax rate as compared to a 35% tax rate for
1994. The reduction in the 1995 rate is due to a higher estimated percentage
depletion allowance.
 
Net Income
 
     Net income of $35.8 million, or $2.66 per share, during 1995 was $13.6
million, or $0.90 per share higher than the prior-year pro forma results.
Excluding the after-tax effect of $4.2 million related to a litigation recovery
included in the 1994 pro forma results, net income in 1995 was $17.8 million or
$1.19 per share higher than 1994. This improvement is primarily due to higher
cement results, reflecting 15% higher average net realized cement selling prices
partly offset by lower results from the construction aggregates and ready-mixed
concrete operations. Also contributing to the favorable increase in net income
for 1995 over the prior-year pro forma results were higher earnings from Kosmos
Cement Company, lower overall cost of goods sold (associated with the lower
sales volumes in all major product lines) and decreased selling, general and
administrative expenses.
 
NINE MONTHS ENDED DECEMBER 31, 1994
 
Net Sales
 
     Consolidated net sales for the nine months ended December 31, 1994 were
$261.6 million following the Company's emergence from bankruptcy in April 1994.
Cement operations recorded sales of $176.7 million for the nine-month period
ended December 31, 1994. Cement sales for the nine-month period from comparable
operations were $18.7 million higher than the prior year comparable period
reflecting a 13% increase in average net realized selling prices and a 2%
increase in cement shipments. The increase in cement shipments, particularly
from the Cape Girardeau, Missouri and the Greencastle, Indiana cement plants,
and higher average net realized selling prices at all locations, resulted from
strong demand in all local markets.
 
     Sales of construction aggregates were $47.7 million for the nine-month
period ending December 31, 1994. Sales of construction aggregates increased $4.7
million from the comparable prior year nine-month period primarily due to a 7%
increase in shipments. Increased shipments of construction aggregates in the New
York metropolitan area were partly offset by decreased shipments from the
Company's Canadian operations.
 
     Ready-mixed concrete and other operations recorded sales of $37.2 million
for the nine-month period ended December 31, 1994. The increase in ready-mixed
concrete sales of $7.9 million was attributed to a 24% increase in shipments and
an 8% increase in prices as compared to the comparable prior-year period.
Shipments of ready-mixed concrete were favorable at all locations during this
period, particularly in the Memphis, Tennessee area where strong demand from
increased commercial building resulted in both higher shipments and favorable
prices.
 
                                       16
<PAGE>   19
 
     Net sales of cement, construction aggregates and ready-mixed concrete and
other products contributed 68%, 18% and 14%, respectively, to total sales for
the 1994 nine-month period.
 
Gross Profits
 
     Gross profits from the cement operations were $54.4 million for the nine
months ended December 31, 1994, primarily reflecting the 13% increase in overall
average net realized selling prices and higher cement shipments. Also
contributing to the favorable cement gross profits were favorable per unit
production costs at the Cape Girardeau, Missouri cement plant reflecting
operating efficiencies due to increased production volumes. The positive results
were partly offset by higher production costs at the other locations,
particularly the Greencastle, Indiana facility, which was affected by higher
coal costs and lower waste fuel revenues due to the decreased use of waste fuels
in the production process. In September 1993, the Greencastle plant temporarily
suspended the use of hazardous waste fuels pending analysis of the
administrative enforcement action commenced by the EPA. The Company resumed
burning hazardous waste fuel in 1994, but on a substantially reduced basis
throughout the year, resulting in decreased revenues and higher coal costs.
 
     Gross profits from the construction aggregates operations were $8.3 million
for the 1994 nine-month period reflecting a 7% increase in overall shipments and
a 6% increase in overall average net realized selling prices from the comparable
prior-year period. Shipments from the New York Trap Rock operation increased 15%
over the comparable period. This increase reflects higher shipments in the
second quarter of 1994 caused by the prolonged and adverse winter weather
conditions experienced during the first quarter in the Northeast, which delayed
the opening of customer asphalt and ready-mixed concrete plants until March. In
addition, the Company's customers were adversely affected by strikes in the
summer of 1993 which did not occur in 1994. Also contributing to the favorable
construction aggregates gross profits were favorable per unit production costs
from the West Nyack, New York operation due to increased production volumes. The
positive results were partly offset by decreased shipments from the Canadian
operation, due to the lack of available ships to transport product to its
coastal U.S. and Caribbean markets and lower overall customer demand.
 
     Gross profits from ready-mixed concrete and other construction products
were $5.7 million for the nine-month period ended December 31, 1994 primarily
due to the increase in overall shipments and average net realized selling
prices, reflecting strong demand in the Memphis, Tennessee and central Illinois
areas.
 
     Included in the calculation of gross profit are sales less cost of sales
including depreciation related to cost of sales (which excludes depreciation
related to facilities leased to third parties and depreciation on office
equipment, furniture and fixtures which are not related to the cost of sales).
 
Joint Ventures
 
     Pre-tax income from joint ventures of $4.4 million for the nine months
ended December 31, 1994 reflects the results of the Kosmos Cement Company.
Results from Kosmos Cement Company were $1.1 million higher from the comparable
prior-year period reflecting increased shipments and higher net realized selling
prices. The RMC LONESTAR and Hawaiian Cement joint ventures were transferred to
Rosebud in connection with the plan of reorganization.
 
Other Income
 
     Other income of $3.8 million for the nine-month period ended December 31,
1994 primarily reflects interest earned on investments, rental income and
interest earned on accounts and notes receivable.
 
Selling, General and Administrative Expenses
 
     Selling, general and administrative expenses of $23.7 million for the nine
months ended December 31, 1994 reflects savings achieved during and after the
Company's bankruptcy proceedings. The savings in selling, general and
administrative expenses primarily reflect lower other postretirement benefit
expense and lower pension expense due to settlements reached through
negotiations with retirees including the establishment of a Voluntary Employee
Beneficiary Association ("VEBA") for salaried retirees whereby the Company makes
quarterly contributions to a trust. The Company also reached a settlement with
the PBGC whereby the Company contributed additional cash to its pension plans.
Lower insurance expenses also contributed to the savings in selling, general and
administrative expenses reflecting settlements reached with insurance carriers
and the Company's joint ventures and certain former joint ventures which
 
                                       17
<PAGE>   20
 
settled certain ultimate liabilities for periods prior to the petition date.
Other savings in selling, general and administrative expenses reflect lower
employee-related expenses primarily achieved by reductions in personnel, prior
to June 30, 1994 through attrition, combined with a corporate downsizing on June
30, 1994 which eliminated approximately 35% of salaried positions at the
corporate office. Selling, general and administrative expenses for the
nine-month period ended December 31, 1994 include $4.6 million of other
postretirement benefit costs related to the Company's presently retired
employees. In addition, selling, general and administrative expenses for the
nine-month period include $0.5 million relating to the filing of a registration
statement.
 
Interest Expense
 
     Interest expense of $6.8 million for the nine months ended December 31,
1994 was comprised primarily of interest accrued on the $78.0 million 10% senior
notes and the Company's obligation relating to the production payment.
 
Income Taxes
 
     The income tax expense of $15.8 million primarily reflects taxes computed
at the U.S. statutory rate in addition to net state taxes and foreign subsidiary
taxes.
 
Net Income
 
     Net income for the nine-month period ended December 31, 1994 of $29.3
million, or $2.22 per share, reflects higher cement and ready-mixed concrete
shipments and selling prices combined with reduced selling, general and
administrative expenses. Net income for the nine months reflects joint venture
income of $4.4 million, which represents the Company's share of earnings from
Kosmos Cement Company. The RMC LONESTAR and Hawaiian Cement partnerships were
transferred to Rosebud in connection with the Plan of Reorganization. The
positive net income for the current period was partly offset by higher interest
expense primarily related to the senior notes.
 
     For years subsequent to 1994, first quarter results have reflected and are
expected to continue to reflect losses (which may be significant), due to the
impact of the winter months on construction activity, particularly at the
Company's northern operations, production curtailments at plants to perform
annual maintenance, and higher costs associated with the annual maintenance.
Historically, for accounting purposes planned capacity variances during a fiscal
year were deferred in the first quarter and recognized during the last nine
months. These deferred costs in 1994 totaling $8.4 million were written off as
part of the revaluation of assets in accordance with fresh-start reporting.
Beginning in 1995, due to a change in the Company's accounting policies, these
costs will be expensed more quickly than in prior years and will primarily
impact first quarter results of the year in which they occur.
 
THREE MONTHS ENDED MARCH 31, 1994
 
Net Sales
 
     Consolidated net sales of $33.7 million for the three months ended March
31, 1994 were $1.2 million higher than the comparable prior year period
reflecting higher shipments of cement and ready-mixed concrete, partially offset
by lower sales of construction aggregates. Cement sales of $24.6 million were
$2.4 million greater than the comparable prior-year period reflecting increased
domestic cement shipments particularly from the Cape Girardeau, Missouri cement
plant due to stronger demand and higher average net realized cement selling
prices at all locations. The favorable sales volume was partly offset by lower
cement sales from the Nazareth, Pennsylvania cement plant (subsequently
transferred to Rosebud) as shipments were adversely affected by severe winter
weather conditions in the Northeast.
 
     Sales of construction aggregates of $2.8 million for the three months ended
March 31, 1994 were $2.2 million below the comparable prior-year period. The
reduction in shipments of construction aggregates reflects a slow start in
construction activity caused by the prolonged and adverse winter weather
conditions experienced in the Northeast in 1994. These adverse conditions
extended into March, which delayed the opening of customer asphalt and ready-mix
concrete plants. Also contributing to the lower aggregate shipments was the
shortage of available commercial freighters to transport construction aggregates
from the Company's Canadian operation to the Caribbean market.
 
                                       18
<PAGE>   21
 
     Ready-mixed concrete and concrete products sales were $6.1 million for the
three months ended March 31, 1994, which were $1.1 million above the comparable
prior-year period reflecting higher shipments of ready-mixed concrete, concrete
block, and building materials due to increased business activity and higher
average net realized selling prices.
 
Joint Ventures
 
     Pre-tax income from joint ventures of $0.4 million for the first quarter of
1994 was $1.2 million below the comparable prior-year period due to the sale of
the Company's Brazilian joint venture in September 1993 which contributed
pre-tax joint venture earnings of $3.5 million in the first quarter of 1993.
Results from the RMC LONESTAR partnership increased $2.7 million from the
comparable prior-year period due to higher shipments, the result of increased
construction activity, favorable weather conditions, and lower per unit
production costs associated with increased production volumes. Results from the
Hawaiian Cement partnership decreased $0.4 million from the first quarter of
1993 reflecting lower shipments of cement, construction aggregates, and
ready-mixed concrete as a result of a slowdown in the construction industry in
Hawaii. The Company's share of pre-tax income from Kosmos Cement Company
approximated the comparable prior year period's results.
 
Recovery of Litigation Settlement
 
     Included in income in the first quarter of 1994 is an insurance settlement
of $6.5 million from the Company's primary carrier regarding indemnification
pursuant to the railroad crosstie litigation, the right of recovery to such
litigation was subsequently transferred to Rosebud. The settlement was offset
against a bankruptcy claim of that carrier.
 
Cost of Sales
 
     Cost of sales of $29.7 million for the first quarter of 1994 was $1.2
million higher than the comparable prior-year period primarily due to higher
cement and ready-mixed concrete costs reflecting higher shipments. This was
partly offset by lower sales of construction aggregates and the delayed startup
of production at the domestic construction aggregates plants.
 
Selling, General and Administrative Expenses
 
     Selling, general and administrative expenses of $9.8 million for the three
months ended March 31, 1994 were $0.4 million lower than the comparable prior
year period.
 
Reorganization Items
 
     Reorganization items, related to the bankruptcy, of $147.3 million during
the first quarter of 1994 were $144.7 million higher than the comparable
prior-year period primarily reflecting adjustments to fair value of fixed assets
in connection with the adoption of fresh-start reporting, and higher
professional fee expenses and higher administrative costs associated with the
emergence from bankruptcy pursuant to the plan of reorganization.
 
Income Taxes
 
     Income tax expense of $0.2 million for the first quarter of 1994 was $1.7
million lower than the comparable prior-year period reflecting lower foreign
taxes due to the sale of the Brazilian operation in September 1993.
 
Extraordinary Gain
 
     The results of the first quarter of 1994 include an extraordinary gain of
$127.5 million related to the discharge of prepetition liabilities in accordance
with the plan of reorganization.
 
Cumulative Effect of Changes in Accounting Principles
 
     In the first quarter of 1993, the Company's partner in the Kosmos Cement
Company partnership, which owns a 75% interest in the partnership (the Company
owns the remaining 25% interest), adopted Statement of Financial Accounting
Standards No. 106, "Employers Accounting for Postretirement Benefits Other than
Pensions" ("SFAS No. 106"). At the same time Kosmos Cement Company also adopted
SFAS No. 106. As a result, the Company recognized a charge of $0.8
 
                                       19
<PAGE>   22
 
million representing its share of the partnership's cumulative effect of the
change in accounting principle. There were no changes in accounting principles
during the first quarter of 1994.
 
Net Loss
 
     The net loss of $23.1 million for the first quarter of 1994 is $8.9 million
greater than the comparable prior-year period. Included in the first quarter
1994 results are reorganization expenses of $147.3 million relating to
adjustments of assets and liabilities to their respective fair values, and
increased professional fees and administrative costs associated with the
Company's reorganization. These reorganization expenses are partly offset by an
extraordinary gain of $127.5 million due to the discharge of pre-petition
liabilities and a $6.5 million insurance recovery relating to indemnification
pursuant to the railroad crosstie litigation. The first quarter of 1993 results
reflect pre-tax joint venture income of $3.5 million provided by the Brazilian
subsidiary, which was sold in September 1993, and a charge for the cumulative
effect of a change in accounting principle of $0.8 million. Excluding the
pre-tax earnings from the Brazilian joint venture and the insurance recovery,
pre-tax operating results for the first quarter of 1994 were $2.9 million better
than the same prior-year period. This increase reflects higher results from the
cement and ready-mixed operations and domestic joint ventures on higher
shipments due to increased business activity and lower selling, general and
administrative expenses. The increase was partly offset by decreased results
from construction aggregates primarily reflecting lower shipments as a result of
severe winter weather conditions.

ITEM 8.  CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.
 
                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders
Lone Star Industries, Inc.
 
     We have audited the consolidated balance sheets of Lone Star Industries,
Inc. and Consolidated Subsidiaries (the "Company") as of December 31, 1995 and
1994, and the related consolidated statements of operations, shareholders'
equity and cash flows for the year ended December 31, 1995 and the nine months
ended December 31, 1994 (post-confirmation), the three months ended March 31,
1994 and the year ended December 31, 1993 (pre-confirmation). We have also
audited the Financial Statement Schedule II included in this annual report on
Form 10-K. These financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement schedule based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Lone Star Industries, Inc. and Consolidated Subsidiaries as of December 31, 1995
and 1994, and the consolidated results of their operations and their cash flows
for the year ended December 31, 1995, the nine months ended December 31, 1994,
the three months ended March 31, 1994 and the year ended December 31, 1993, in
conformity with generally accepted accounting principles. In addition, in our
opinion, the financial statement schedule referred to above, when considered in
relation to the basic financial statements taken as a whole, presents fairly, in
all material respects, the information required to be included therein.
 
     As discussed in Notes 1 and 23, effective April 14, 1994, the Company was
reorganized under a plan confirmed by the United States Bankruptcy Court for the
Southern District of New York and adopted a new basis of accounting whereby all
remaining assets and liabilities were adjusted to their estimated fair values.
Accordingly, the consolidated financial statements for periods subsequent to the
reorganization are not comparable to the consolidated financial statements
presented for prior periods.

                         NOTES TO FINANCIAL STATEMENTS
 
1. DESCRIPTION OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
     Description of Operations -- The Company is a cement, construction
aggregates and ready-mixed concrete company, with operations in the United
States (principally in the Midwest and Southwest and on the East Coast) and
formerly in Nova Scotia, Canada. Lone Star's cement operations consist of five
cement plants in the midwestern and southwestern regions of the United States
and a 25% interest in Kosmos Cement Company, a partnership which operates one
cement plant in each of Kentucky and Pennsylvania. These five wholly-owned
cement plants produced approximately 3.8 million tons of cement in 1995, which
approximates the rated capacity of such plants. In 1995 the Company's aggregate
operations served the construction markets in the New York Metropolitan area,
the East Coast and Gulf Coast of the United States, the Caribbean and the Nova
Scotia and Prince Edward Island areas of Canada. The ready-mixed concrete
business operates in central Illinois and the Memphis, Tennessee area. The
Company had approximately $323,000,000 in net sales in 1995, with cement,
construction aggregates and ready-mixed concrete and other construction products
operations representing approximately 73%, 15% and 12%, respectively, of such
net sales.
 
     Demand for cement is derived primarily from residential construction,
commercial and industrial construction and public (infrastructure) construction
which are highly cyclical and are influenced by prevailing economic conditions
including interest rates and availability of public funds. Due to cement's low
value-to-weight ratio, the industry is largely regional and regional demand is
tied to local economic factors that may fluctuate more widely than those of the
nation as a whole.
 
     The markets for the Company's products are highly competitive and portland
cement is largely a commodity product. The Company competes with domestic and
international sources largely on the basis of price. To a lesser extent, other
competitive factors such as service, delivery time and proximity to customers
affect the Company's performance.
 
     Basis of Presentation -- The consolidated financial statements include the
accounts of Lone Star Industries, Inc. and all domestic and foreign
subsidiaries. All intercompany transactions have been eliminated. Joint ventures
are accounted for using the equity method. Certain prior-period amounts have
been reclassified to conform with current-period presentation.
 
     The Company adopted "fresh-start" reporting in accordance with AICPA
Statement of Position No. 90-7, "Financial Reporting by Entities in
Reorganization Under the Bankruptcy Code" ("SOP No. 90-7"), as of March 31,
1994. The Company's emergence from its Chapter 11 proceedings resulted in a new
reporting entity with no retained earnings or accumulated deficit as of March
31, 1994. Accordingly, the Company's consolidated financial statements for
periods prior to March 31, 1994 are not comparable to consolidated financial
statements presented on or subsequent to March 31, 1994. A black line has been
drawn on the accompanying consolidated financial statements to distinguish
between the pre-reorganization and post-reorganization company. In addition,
having operated for over three years in bankruptcy, results of operations prior
to emergence from bankruptcy are not indicative of results of operations outside
of Chapter 11 proceedings.
 
     In accordance with the Company's plan of reorganization (See Note 23),
certain non-core assets of the Company and their associated liabilities were
transferred to Rosebud Holdings, Inc., a wholly-owned liquidating subsidiary and
its subsidiaries (collectively "Rosebud"), for disposition and distribution of
the proceeds of such dispositions, for the benefit of unsecured creditors (See
Note 25). The Company's investment in Rosebud is recorded at the lower of the
estimated net realizable value of the assets or face value of the asset proceeds
notes (See Note 25).
 
     Cash and Cash Equivalents -- Cash equivalents include short-term, highly
liquid investments with original maturities of three months or less, and are
recorded at cost, which approximates market value.
 
     Inventories -- Inventories are stated at the lower of cost or market. Cost
is determined principally by the weighted average cost method.
 
     Property, Plant and Equipment -- Property, plant and equipment were stated
at fair market value as of March 31, 1994. Additions subsequent to March 31,
1994 are stated at cost. Property, plant and equipment are depreciated over the
estimated useful lives of the assets using the straight-line method. Significant
expenditures which extend the useful lives

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
of existing assets are capitalized. Maintenance and repair costs are charged to
current earnings. Cost depletion is calculated using the units of production
method. The cost of assets and related accumulated depreciation is removed from
the accounts when such assets are disposed of, and any related gains or losses
are reflected in current earnings.
 
     Income Taxes -- Deferred income taxes are provided for the temporary
differences between the financial reporting basis and the tax basis of the
Company's assets and liabilities. In accordance with SOP No. 90-7, income tax
benefits resulting from the realization of preconfirmation deferred tax assets
are used first to reduce reorganization value in excess of amounts allocable to
identifiable assets and then to increase additional paid-in capital.
 
     Pension Plans -- The Company and certain of its consolidated subsidiaries
have a number of retirement plans which cover substantially all of its
employees. Defined benefit plans for salaried employees provide benefits based
on employees' years of service and five-year final pay compensation for a
specified period of time. Defined benefit plans for hourly paid employees,
including those covered by multi-employer pension plans under collective
bargaining agreements, generally provide benefits of stated amounts for
specified periods of service. The Company's policy is to fund amounts as are
necessary on an actuarial basis to provide assets sufficient to meet the
benefits to be paid to plan members in accordance with the requirements of the
Employees Retirement Income Security Act of 1974 ("ERISA"). Assets of the plans
are administered by an independent trustee and are invested principally in fixed
income, equity securities and real estate.
 
     Postretirement Benefits Other Than Pensions -- The Company provides retiree
life insurance and health plan coverage to qualifying employees. The Company
accounts for these benefits on an accrual basis, under the provisions of
Statement of Financial Accounting Standards No. 106, "Employers' Accounting for
Postretirement Benefits Other than Pensions". These plans are unfunded.
 
     Income Per Common Share -- Primary and fully diluted income per common
share is based on the weighted average number of shares outstanding in each year
and includes warrants to purchase common stock and dilutive stock options as
common stock equivalents. Due to the large number of outstanding common stock
equivalents, primary and fully diluted earnings per share of the successor
company are calculated using the modified treasury stock method. Primary and
fully diluted earnings per share for the year ended December 31, 1995 were based
on adjusted weighted average shares outstanding of 14,336,774 and adjusted net
income of $38,096,000 and $37,610,000, respectively. Primary and fully diluted
earnings per share for the nine months ended December 31, 1994 were based on
adjusted weighted average shares outstanding of 14,132,145 and adjusted net
income of $31,427,000 and $31,341,000, respectively.
 
     Environmental Matters -- Accruals for environmental matters are recorded
when it is probable that a liability has been incurred and the amount of the
liability can be reasonably estimated, or if an amount is likely to fall within
a range and no amount within that range can be determined to be the better
estimate, the minimum amount of the range is recorded. Accruals for
environmental matters exclude claims for recoveries from insurance carriers and
other third parties until it is probable that such recoveries will be realized.
 
     Recently Issued Accounting Pronouncements -- The Company accounts for
stock-based compensation in accordance with Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees" and has not yet determined
whether it will choose to recognize compensation expense or opt to comply with
the disclosure requirements when Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" is adopted in 1996.
 
     In March 1995, Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" ("SFAS No. 121") was issued, effective January 1, 1996. SFAS No.
121 requires that in the event certain facts and circumstances indicate an asset
may be impaired, an evaluation of recoverability must be performed to determine
whether or not the carrying amount of the asset is required to be written down.
The Company does not expect the adoption of this statement to have a material
effect on its financial condition or results of operations.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.

     Due to the nature of the Company's products, a majority of the Company's
accounts receivable are from businesses in the construction industry. Although
the Company's customer base is geographically diversified, collection of
receivables is partially dependent on the economics of the construction
industry.

8. ASSET PROCEEDS NOTES OF LIQUIDATING SUBSIDIARY
 
     Upon emergence from the Company's Chapter 11 proceedings, Rosebud issued
secured asset proceeds notes in the aggregate principal amount of $138,118,000.
The notes bear interest at a rate of 10% per annum payable in cash and/or
additional asset proceeds notes, payable semi-annually. The notes are to be
repaid as Rosebud's assets are disposed of and proceeds are received in
connection with the litigation transferred to Rosebud. The asset proceeds notes
mature on July 31, 1997.
 
     In July 1994, January 1995 and July 1995, Rosebud made cash interest
payments of $5,755,000, $5,320,000 and $2,570,000, respectively. An additional
cash interest payment of $209,000 was made in January 1996. Principal payments
of $31,878,000, $30,183,000, $26,090,000, $12,300,000 and $36,361,000 including
accrued interest thereon, were made in August 1994, February 1995, July 1995,
October 1995 and December 1995, respectively. As of December 31, 1995, the total
interest and principal payments paid on the assets proceeds notes was
$150,457,000.
 
     The asset proceeds notes are recorded on the accompanying consolidated
balance sheets at their face value at December 31, 1995 and at the estimated net
value of the assets at December 31, 1994(See Note 25).
 
9. SENIOR NOTES PAYABLE
 
     Upon emergence from its Chapter 11 proceedings, the Company issued
$78,000,000 of ten year senior unsecured notes due July 31, 2003, which bear
interest at a rate of 10% per annum. The indenture governing the senior notes
and other agreements entered into in connection with the reorganization impose
certain operating and financial restrictions on the Company. Such restrictions
affect, and in some respects limit or prohibit, among other things, the ability
of the Company to incur additional indebtedness, create liens, engage in mergers
and acquisitions, purchase the Company's capital stock or pay dividends.
 
     Commencing in the year 2000, the Company is required to make three annual
payments of $10,000,000 each into a sinking fund account for redemption of the
senior notes. The amount of any such required sinking fund account will be
reduced, without duplication, by the principal amount of any senior notes that
the Company has optionally redeemed or purchased.
 
     The Company has the option to redeem the senior notes payable for an amount
equal to 100% of the principal amount plus accrued and unpaid interest. Optional
redemption of the senior notes is restricted by the Company's credit agreement.

10. CREDIT AGREEMENT
 
     Upon emergence from Chapter 11, the Company entered into a three-year
$35,000,000 revolving credit agreement which is collateralized by inventory,
receivables, collection proceeds and certain intangible assets. The Company's
borrowings under this agreement are limited to 55% of eligible inventory plus
85% of eligible receivables. The agreement was subsequently amended in April,
November and December 1995. The amendments reduced the rates of interest under
the agreement and increased the amounts allowed for capital expenditures and
certain other payments. The advances under the agreement bear interest at a rate
of either prime plus 0.5% or LIBOR plus 2.25%, at the Company's option. A fee of
0.375% per annum is charged on the unused portion of the line. Although the
Company from time to time has used the letter of credit facility provided by the
credit agreement, it has not drawn any funds under the credit agreement for
working capital purposes. Accordingly, there was no outstanding balance as of
December 31, 1995.
 
     The credit agreement and other agreements entered into in connection with
the reorganization, impose certain operating and financial restrictions on the
Company. Such restrictions affect, and in some respects limit or prohibit, among
other things, the ability of the Company to incur additional indebtedness, repay
certain indebtedness prior to its stated maturity, create liens, engage in
mergers and acquisitions, make certain capital expenditures or pay dividends. In
addition, pursuant to the credit agreement and other agreements entered into in
connection with the reorganization certain of the Company's assets are subject
to liens or negative pledges.
 
11. PRODUCTION PAYMENT
 
     The Company entered into a production payment arrangement concerning
specific limestone reserves located adjacent to two cement plants, and pursuant
to the terms of the document, was obligated to extract and process those
reserves into cement for the purchaser free and clear of all expenses. The
proceeds were deferred and were reflected in income, together with related costs
and expenses, as the limestone was processed into cement and the cement was
sold.
 
     As part of the plan, the terms of the production payment agreement were
revised as of April 14, 1994. Under the revised terms, the Company was required
to make payments in advance for minerals used at the two plants subject to the
production payment agreement and to take or pay for minerals in amounts
sufficient to permit the purchaser to service the note associated with the
production payment facility. In connection therewith, a new note was issued,
with an outstanding principal balance of $20,963,000 as of that date, and which
bore interest, at the Company's option, at a rate of either prime or LIBOR plus
1.75% through December 31, 1995 and either prime plus 0.25% or LIBOR plus 2.5%
beginning on January 1, 1996. In January and July 1995, the Company made total
scheduled principal payments of $3,000,000 and in December 1995 the Company paid
the remaining outstanding production payment balance of $16,966,000.
 
12. LEASES
 
     Net rental expense for the year ended December 31, 1995, the nine months
ended December 31, 1994, the three months ended March 31, 1994, and the year
ended December 31, 1993 was $4,908,000, $4,894,000, $755,000 and $5,888,000,
respectively. Minimum rental commitments under all non-cancelable leases
principally pertaining to land, buildings and equipment are as follows:
1996 -- $1,679,000; 1997 -- $1,455,000; 1998 -- $1,028,000; 1999 -- $968,000,
and as of December 31, 1995 there were no commitments subsequent to 1999.
Certain leases include options for renewal or purchase of leased property.
 
     A subsidiary of the Company was leasing its Florida cement plant with an
original term of approximately twenty years at an annual rental of $2,500,000.
In June 1994, the Company sold its interest in the cement plant located in
Florida, for $21,750,000, which approximated book value.
 
13. PENSION PLANS
 
     The Company sponsors a number of defined benefit retirement plans which
cover substantially all employees. Defined benefit plans for salaried employees
provide benefits based on employees' years of service and five-year final pay
compensation. Defined benefit plans for hourly paid employees generally provide
benefits of stated amounts for specified

     The weighted average discount rates of 7.0% and 7.5% for 1995 and 1994,
respectively, and the rate of annual increase in future compensation levels of
4.5% for 1995 and 5.5% for 1994, were used in determining the actuarial present
values of the projected benefit obligation. The expected long-term rate of
return on plan assets was 8.0% for both 1995 and 1994.
 
     Upon adoption of fresh-start reporting, pension liabilities were recorded
based on the unfunded projected benefit obligation as of March 31, 1994. All
outstanding unamortized and unrecognized items as of March 31, 1994 were
recognized and recorded on the Company's consolidated balance sheet.
 
     Certain union employees are covered under multi-employer defined benefit
plans administered under collective bargaining agreements. Multi-employer
pension expenses and contributions to the plans in the year ended December 31,
1995, the nine months ended December 31, 1994, the three months ended March 31,
1994 and the year ended December 31, 1993 were approximately $300,000, $200,000,
$50,000 and $300,000, respectively.
 
     In accordance with the plan of reorganization, future obligations are
secured by the grant to the PBGC of a mortgage on the Oglesby, Illinois cement
plant and a security interest in the Kosmos Cement Company partnership.

14. POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
     The Company provides retiree life insurance and health plan coverage to
employees qualifying for early, normal or disability pension benefits under the
Company's salaried employees pension plan and certain of the pension plans
providing for hourly-compensated employees. Life insurance protection presently
provided to retirees under the salaried employees pension plan is one-half their
active employment coverage declining to 25% of their active employment coverage
at age 70. The coverage provided under hourly plans is fixed, as provided under
the terms of the plans. Health care coverage presently is extended to retirees
and their qualified dependents during the retirees' lifetime. The coverage
provided assumes participation by the retiree in the Medicare program and
benefit payments are integrated with Medicare benefit levels. The Company's
postretirement benefit plans other than pension plans are not funded. Claims are
paid as incurred.
 
     Upon adoption of fresh-start reporting, postretirement benefit liabilities
were recorded based on the unfunded accumulated postretirement benefit
obligation as of March 31, 1994. All outstanding unamortized and unrecognized
postretirement benefit items as of March 31, 1994 were recognized and recorded
on the Company's consolidated balance sheet.
 
     As part of its emergence from Chapter 11 proceedings, the Company reached
settlements with the salaried and union retirees with respect to reductions and
modifications of retiree medical and life insurance benefits. As part of the
settlement with salaried retirees, the Company established a Voluntary Employees
Beneficiary Association ("VEBA"), a tax-exempt trust, and agreed to make defined
quarterly contributions to the trust. The Company has the option to prepay all
future quarterly contributions to the VEBA in a single cash amount equal to 110%
of the discounted present value (using an 8.5% discount factor) of all future
quarterly contributions. The Company made contributions of $4,378,000 and
$3,705,000 to the VEBA during the year ended December 31, 1995 and the nine
months ended December 31, 1994.
 
     Net periodic postretirement benefit cost for the year ended December 31,
1995, the nine months ended December 31, 1994, the three months ended March 31,
1994 and the year ended December 31, 1993 included the following components (in

</TABLE>
 
     The weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 7.0% and 7.5% for 1995 and 1994,
respectively. Compensation levels are assumed to increase annually at a rate of
4.5% in 1995 and 5.5% in 1994.
 
     For measurement purposes, a 12.5% and 10.0% annual medical rate of increase
was assumed for 1995 for pre-medicare and post-medicare claims, respectively;
the rate was assumed to decrease  1/2% each year to 6.0% per year after 2007 for
pre-medicare claims, and decrease  1/2% per year to 6.0% after 2002 for
post-medicare claims. The health care cost trend rate assumption has a
significant effect on the amounts reported. To illustrate, increasing the
assumed health care cost trend rates by 1 percentage point in each year would
increase the accumulated postretirement benefit obligation as of December 31,
1995 by approximately $8,800,000 and the aggregate of the service and interest
cost components of net periodic postretirement benefit cost for the year ended
December 31, 1995 by approximately $974,000.
 
     In the first quarter of 1993, the Kosmos Cement Company partnership, in
which the Company owns a 25% interest, adopted SFAS No. 106. As a result, the
Company recognized a charge of $782,000 or $0.05 per share representing its
share of the partnership's cumulative effect of the change in accounting
principle.
 
15. COMMON STOCK
 
     Upon emergence from its Chapter 11 proceedings, the Company authorized
25,000,000 shares of $1.00 par value common stock and issued 12,000,000 shares
of that common stock (See Note 23). In 1995, the authorized number of shares of
common stock was increased from 25,000,000 to 50,000,000. Transactions in common
stock are as follows:

and the exercise of stock options (673,312 shares). The payment of cash
dividends on common stock is restricted under the provisions of the Company's
debt agreements (See Notes 9 and 10). As of December 31, 1995, $10,000,000 was
available for the payment of dividends under the Company's most restrictive
agreement.
 
     In April 1995, the Company's revolving credit agreement was amended. The
amendment, among other changes, revised the limitation on paying dividends. In
April, August and November 1995, the Board of Directors declared $0.05 dividends
per common share, which were paid on June 15, 1995, September 15, 1995 and
December 15, 1995 to shareholders of record as of June 1, 1995, September 1,
1995 and December 1, 1995, respectively. In addition, on February 1, 1996, the
Board of Directors declared a $0.05 dividend per common share, payable on March
15, 1996 to shareholders of record as of March 1, 1996.
 
     On April 18, 1995, the Board of Directors approved a plan to repurchase
common stock from shareholders who own less than 100 shares, and to allow
shareholders to increase their shares owned up to 100 shares. The original
program was extended through July 28, 1995. No brokerage commissions were
incurred by shareholders related to these transactions. A total of 24,454 shares
were tendered for sale by the shareholders and shareholders purchased 20,297
shares, under this program.
 
     In November 1995, the Board of Directors authorized the expenditure of up
to $20,000,000 for the repurchase of the Company's common stock. In November
1995, the Company repurchased 600,000 shares of its common stock for
$13,875,000.
 
16. WARRANTS TO PURCHASE COMMON STOCK
 
     Upon emergence from its Chapter 11 proceedings, the Company issued
4,003,333 warrants to purchase common stock at an exercise price of $18.75 per
share. Each warrant entitles the holder thereof to purchase one share of common
stock. The warrants are non-callable, non-redeemable and expire on December 31,
2000. As of December 31, 1995, 3,999,177 warrants were outstanding.
 
     The number of shares of common stock purchasable upon the exercise of each
warrant and the exercise price of the warrant are subject to adjustment if the
Company (i) pays a dividend in shares of common stock, (ii) subdivides its
outstanding shares of common stock, (iii) combines its outstanding shares of
common stock into a smaller number of shares of common stock, or issues by
reclassification or recapitalization of its shares of common stock, other
securities of the Company or (iv) issues certain stock rights convertible into,
or exchangeable for, common stock. An adjustment will not result from the
Company's sale of common stock on the open market or from the declaration of
regular cash dividends.
 
17. STOCKHOLDER RIGHTS PLAN
 
     In November 1994, the Board of Directors adopted a Stockholder Rights Plan
("rights plan") under which stock purchase rights were distributed as a dividend
to holders of common stock payable to the shareholders of record on December 19,
1994. Management believes that the rights plan represents a means of deterring
abusive and coercive takeover tactics not offering an adequate price to all
stockholders, and seeks to ensure that stockholders realize the long-term value
of their investments.
 
     The rights plan provides that if, subject to certain exemptions, any person
or group acquires 15% or more of the Company's common stock, each right not
owned by a 15% or more stockholder or related parties will entitle its holder to
purchase, at the right's then current exercise price, shares of common stock
having a value of twice the right's then current exercise price. This right to
purchase common stock at a discount will not be triggered by a person's or
group's acquisition of 15% or more of the common stock pursuant to a tender or
exchange offer which is for all outstanding shares at a price and on terms that
the Board of Directors determines (prior to acquisition) to be adequate and in
the best interests of the Company and its stockholders. In addition, this right
will not be triggered by the stockholdings of certain existing stockholders.

                           LONE STAR INDUSTRIES, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Under the rights plan, holders of the rights will initially be entitled to
buy one one-tenth of a share of the Company's common stock at an exercise price
of $70.00 for each whole share which a holder of rights may purchase. Until a
person or group acquires 15% or more of the common stock or commences a tender
or exchange offer for 15% or more of the common stock, the rights will attach to
and trade with the common stock. The rights will expire in the year 2004.
 
     The Company may redeem the rights, at the option of the Board of Directors,
at a redemption price of $0.01 per right at any time prior to the acquisition by
any person or group of 15% or more of the common stock. In addition, after a
person or group has acquired 15% or more of the common stock but before any
person or group has acquired 50% or more of the common stock, the Company may
exchange shares of common stock for rights.
 
18. STOCK OPTIONS
 
     Upon emergence from its Chapter 11 proceedings, the Board of Directors of
the Company adopted the Lone Star Industries, Inc. Management Stock Option Plan
("Management Plan") and the Lone Star Industries, Inc. Directors Stock Option
Plan ("Directors' Plan"). All options will expire 10 years from the date of
grant.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value:
 
     Cash and cash equivalents -- the carrying amount approximates fair value
because of the short maturity of those instruments.
 
     Asset proceeds notes of liquidating subsidiary -- the fair value of the
asset proceeds notes represents the amount expected to be paid by the
liquidating subsidiary which is equal to the lesser of the value of the net
assets of the liquidating subsidiary to be utilized to liquidate these
obligations or the face value of the notes(See Note 25). The face value of the
notes at December 31, 1995 is $4,399,000, and the notes are not publicly traded.
 
     Senior notes payable -- the fair value of long-term debt is based on quoted
market prices. As of December 31, 1995 the senior notes were trading at 102.063%
of face value.

     As of December 31, 1995, the Company has investment tax credit
carryforwards for federal income tax purposes of $5,940,000 which expire at
various dates through 2001. The Company also has regular tax and alternative
minimum tax net operating loss carryforwards of approximately $201,000,000 and
$56,000,000, respectively, which expire at various dates through 2009 and an
alternative minimum tax credit carryforward of $6,575,000. The Internal Revenue
Code of 1986, as amended (the "Code"), imposes limitations under certain
circumstances on the use of carryforwards upon the occurrence of an "ownership
change" (as defined in Section 382 of the Code). An "ownership change" resulted
from the issuance of equity securities by the Company as part of its plan of
reorganization (See Note 23). Such an "ownership change" could limit the use or
continued availability of the Company's carryforwards. Under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" a portion
of these carryforwards has been used for

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     In accordance with AICPA Statement of Position No. 90-7, "Financial
Reporting by Entities in Reorganization Under the Bankruptcy Code", income tax
benefits including those realized from preconfirmation net operating loss
carryforwards were used first to reduce the reorganization value in excess of
amounts allocable to identifiable assets and then increase to paid-in capital.
 
     Net income taxes paid during the year ended December 31, 1995, the nine
months ended December 31, 1994, the three months ended March 31, 1994 and the
year ended December 31, 1993 were $395,000, $86,000, $756,000 and $1,038,000,
respectively.
 
22. ASSET DISPOSITIONS
 
     In December 1995, the Company sold its concrete railroad cross-tie plant
and office building in Denver, Colorado for $2,250,000, which approximated book
value.
 
     In October 1995, the Company sold the assets of its Nova Scotia, Canada
aggregate quarry including working capital for $11,408,000, which approximated
book value.
 
     In February, March and June 1995, the Company sold the assets of its hollow
metal door/hardware business in Illinois, a piece of surplus property in
Mississippi and a cement terminal in Florida for $290,000, $325,000 and
$390,000, respectively. The Company had been leasing the terminal to the buyer
prior to the sale.
 
     In June 1994, the Company sold its interest in a cement plant located in
Florida for $21,750,000, which approximated book value. The plant had been
leased to a third party and was purchased by the lessee.
 
     In March 1993, the Company sold substantially all of the equipment and
inventory of Southern Aggregates for $721,000.
 
     In September 1993, the Company sold its 49.6% interest in Companhia
Nacional de Cimento Portland, a Brazilian joint venture, for $69,629,000 in
cash. A pre-tax loss of $37,335,000, offset by a tax benefit of $12,500,000, was
recognized on the transaction and is included in reorganization items in the
accompanying consolidated statement of operations.
 
     In September 1993, the Company sold one of its cement terminals which had
been leased to a third party, for $812,000.
 
     The operations sold in 1995, 1994 and 1993 contributed the following
results for the period through their respective dates of disposition (in

23. CHAPTER 11 PROCEEDINGS AND THE ADOPTION OF "FRESH-START" REPORTING
 
     On February 17, 1994, with the approval of all voting classes of creditors
and equity holders, the United States Bankruptcy Court for the Southern District
of New York confirmed the Debtors Modified Amended Consolidated Plan of
Reorganization dated November 4, 1993 (as further modified on February 17, 1994)
(the "plan"). On April 14, 1994, (the "effective date") the plan became
effective, and distributions to creditors and shareholders commenced. In
accordance with the plan, certain core cement, ready-mixed concrete and
construction aggregates operations constitute the reorganized Lone Star. Other
non-core assets of the Company and their associated liabilities were transferred
to Rosebud Holdings, Inc., a wholly-owned liquidating subsidiary and its
subsidiaries (collectively "Rosebud") for disposition and distribution of the
proceeds of such dispositions, for the benefit of unsecured creditors (See Note
25).
 
                                       41

                           LONE STAR INDUSTRIES, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The plan provided for distributions on the effective date to claims which
were allowed at that time, and for the establishment of a reserve for certain
disputed, contingent and unliquidated claims. On the effective date, the escrow
agent administering the reserve received a distribution of cash and securities
attributable to the reserved claims. As of the effective date, the total amount
of allowed and reserved claims was $590,944,000, which the Company expects to be
reduced to approximately $584,016,000 when all claims are paid. In connection
with the plan, holders of allowed and reserved secured claims, priority claims
and convenience claims were paid $8,262,000 in cash. Holders of allowed and
reserved unsecured claims, which the Company estimates will be $575,754,000 when
all claims are paid, were entitled to receive their pro rata share of (i)
$192,189,000 in cash, (ii) $78,000,000 ten year 10% senior unsecured notes of
the reorganized Company, (iii) $138,118,000 secured asset proceeds notes of
Rosebud, to be paid out of the proceeds from the disposition of its assets (See
Notes 8 and 25) and (iv) 85.0% of the common stock of reorganized Lone Star.
 
     Holders of the Company's cumulative convertible preferred stock received a
pro rata share of 10.5% of the common stock of reorganized Lone Star and
1,250,000 warrants to purchase common stock of the reorganized Lone Star. The
holders of common stock of Lone Star received the balance of reorganized Lone
Star's common equity and 2,753,333 warrants to purchase common stock in the
reorganized Lone Star. The warrants are exercisable through December 31, 2000,
and each warrant provides for the purchase of one share of the common stock of
reorganized Lone Star at a price of $18.75 per share.
 
     In addition, in accordance with the plan, as part of the agreement with the
Pension Benefit Guaranty Corporation ("PBGC") the Company granted the PBGC a
mortgage on the Oglesby, Illinois plant, and a security interest in the
Company's 25% interest in the Kosmos Cement Company partnership, to secure
certain contingent future pension obligations.
 
     As of the effective date of the plan, the sum of allowed claims plus
post-petition liabilities of the Company exceeded the value of its
pre-confirmation assets. In addition, the Company experienced a change in
control as pre-reorganization equity holders received less than 50% of the
reorganized Lone Star common stock issued pursuant to the plan. Therefore, in
accordance with AICPA Statement of Position No. 90-7, "Financial Reporting by
Entities in Reorganization Under the Bankruptcy Code" ("SOP No. 90-7"), the
Company adopted "fresh-start" reporting which assumes that a new reporting
entity has been created and requires assets and liabilities be adjusted to their
fair values as of the effective date.
 
     Although the plan became effective on April 14, 1994, for accounting
purposes the effective date of the plan is considered to be March 31, 1994, and
accordingly, the Company adopted fresh-start reporting as of March 31, 1994.
Adjustments were recorded as of March 31, 1994 to reflect the effects of the
consummation of the plan and to reflect the implementation of fresh-start
reporting. The reorganization value of the Company was determined using several
factors and by reliance on various valuation methods, including discounted cash
flows, price/earnings ratios and other applicable ratios. Reorganization value
generally approximates fair value of the entity before considering liabilities
and approximates the amount a buyer would pay for the assets of the entity after
the reorganization. Based on information from parties in interest and from Lone
Star's financial advisors, the total reorganization value of the Company was
$579,411,000. The reorganization value was then allocated to the Company's
assets and liabilities in conformity with the Accounting Principles Board
Opinion No. 16, "Business Combinations" ("APB No. 16"), as specified by SOP No.
90-7. Income related to the settlement of liabilities subject to the Company's
Chapter 11 proceedings is included in the accompanying consolidated statement of
operations as an extraordinary gain on discharge of prepetition liabilities. The
gains or losses related to the adjustments of assets and liabilities to fair
value are included in reorganization items in the accompanying consolidated
statement of operations (See Note 26). The reorganization value in excess of
amounts allocable to identifiable assets is the portion of the reorganization
value of the Company which was not attributed to specific assets of the Company.
 
24. PRO FORMA INFORMATION

</TABLE>
 
     The above pro forma condensed financial information includes estimated
adjustments for the following items:
 
     As a result of the implementation of the plan of reorganization and
adoption of fresh-start reporting, the Company's 1989 Restructuring Program
ended effective March 31, 1994. Operating results of the cement plants at Pryor,
Oklahoma and Maryneal, Texas, which were formerly included in assets held for
sale, are included in the pro forma consolidated operating results for the three
months ended March 31, 1994 and the year ended December 31, 1994.
 
     The operating results of the assets and liabilities which were transferred
to Rosebud for distribution for the benefit of creditors have been eliminated
from the pro forma statements of operations.
 
     Cost of sales has been adjusted to reflect the write-up of inventory in
accordance with fresh-start reporting.
 
     In connection with the adjustment of the property, plant and equipment
balances to reflect the values of the assets under fresh-start reporting, the
pro forma consolidated operating results have been adjusted to include the
change in depreciation expense related to the new values.
 
     Interest expense related to long-term debt, including the senior notes of
the reorganized company, has been included in the pro forma statements of
operations.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Due to the elimination of common and preferred shareholders' equity of the
predecessor company, and its replacement with common equity of the successor
company, the provision for preferred dividends has been eliminated from the pro
forma statements of operations.
 
     Cost of sales for the three months ended March 31, 1994 has been adjusted
to reflect the Company's change in its method of accounting for inventory for
interim reporting purposes and the expensing of deferred costs in accordance
with the adoption of fresh-start reporting. In addition, cost of sales has been
adjusted to reflect costs related to its construction aggregates barges which
were deferred during the first quarter of 1994 and subsequently written-off in
accordance with fresh-start reporting. Similar costs will be incurred and
expensed in future years.
 
     All Chapter 11 reorganization items included in the historical statements
of operations have been eliminated from the pro forma statements of operations.
 
     The extraordinary gain on discharge of pre-petition liabilities has been
eliminated.
 
     The pro forma statements of operations have been adjusted, in accordance
with the requirements of fresh-start reporting, to reflect the reduction in
expenses resulting from bankruptcy-related settlements, including settlements
reached with the PBGC and retirees.
 
25. ROSEBUD HOLDINGS, INC. LIQUIDATING SUBSIDIARY
 
     As part of the plan, the Company transferred on April 14, 1994 certain
non-core assets and their related liabilities, certain other miscellaneous
assets, and a $5,000,000 cash investment to be used for working capital
purposes, to Rosebud. The Company is under no obligation to fund additional
Rosebud working capital requirements.
 
     Lone Star's investment in Rosebud, which is comprised of real estate and
cash, net of associated liabilities, is included in the Company's December 31,
1995 consolidated balance sheet at the face value of the asset proceeds notes of
$4,399,000. This reflects the expectation at December 31, 1995 that the net
realizable value of the assets will be, at a minimum, enough to liquidate the
asset proceeds notes in their entirety. Generally, net realized value is the
amount which is reasonably expected to be received upon a sale to a willing
buyer, less costs to sell. Net realizable value may differ from the eventual
realizable value of the assets. In addition, it is difficult to estimate the
time required to complete this process. The asset proceeds notes are recorded on
the accompanying consolidated balance sheet at the lesser of the face value of
the notes or the estimated value of the assets to be utilized to liquidate these
obligations. Prior to December 31, 1995, the Company's investment in Rosebud
reflected the estimated net realizable value of the assets, which was less than
the face value of the asset proceeds notes. The decrease of $82,601,000 from the
December 31, 1994 balance is primarily due to asset sales, certain insurance and
other settlements and the subsequent distribution of the net proceeds to asset
proceeds note holders.
 
     On the effective date of the plan, Rosebud issued secured asset proceeds
notes in the aggregate principal amount of $138,118,000. The asset proceeds
notes are secured by liens and security interests, as the case may be, on
substantially all of the Rosebud assets. The asset proceeds notes bear interest
at a rate of 10% per annum payable in cash and/or additional asset proceeds
notes, payable in semi-annual installments (the July 31, 1994, January 31, 1995,
July 31, 1995 and January 31, 1996 interest payments were paid in cash). The
asset proceeds notes are to be repaid as Rosebud's assets are sold. All net cash
proceeds less a $5,000,000 cash reserve plus up to an additional $5,000,000 for
estimated Rosebud working capital needs, are to be deposited in a cash
collateral account for distribution to the note holders. The asset proceeds
notes mature on July 31, 1997. These notes were guaranteed, in part, by Lone
Star. As a result of the interest and principal payments made by Rosebud, the
Company's guarantee, the guarantee agreement and the related pledge of Rosebud's
common stock owned by the Company were terminated as of July 14, 1995.
 
     Liabilities associated with all Rosebud Assets, sold and unsold, were
assumed by Rosebud and it has agreed to indemnify Lone Star for these
liabilities. The assumption by Rosebud of Lone Star's liabilities may not be
binding upon third parties, and, in any event, as to such liabilities, however,
arising from actions or circumstances that existed on or

before April 14, 1994 and that result in payments to Lone Star aggregating in
excess of $7,000,000, Rosebud's obligation to indemnify Lone Star in respect
thereof is subordinated to repayment of the asset proceeds notes.
 
     In January 1995, Rosebud received $9,000,000 as a return of capital from
the Lone Star-Falcon partnership upon completion of the sale of the
partnership's cement terminals in Texas. In January 1995, Rosebud sold surplus
property in Florida for $1,500,000. In March 1995, Rosebud received proceeds of
$4,000,000 from the sale of surplus property in Texas. In May 1995, Rosebud sold
the stock of a wholly-owned subsidiary, Lone Star California, Inc. and the
promissory notes executed by RMC LONESTAR payable to Lone Star California, Inc.
for cash proceeds of $18,826,000. In June 1995, Rosebud sold surplus property in
Florida for $5,000,000. In January and June 1995, Rosebud sold surplus property
in Louisiana, Maryland and Florida for total proceeds of $954,000. In September
1995, Rosebud sold its 50% interest in Hawaiian Cement, a Hawaiian partnership
for $31,000,000. In October 1995, Rosebud sold surplus property in Texas
receiving $5,000,000 in net proceeds.
 
     During 1994, Rosebud had reached final agreements with substantially all
the insurance carriers involved in litigation, related to indemnity in the
railroad crosstie litigation cases, and received $5,300,000. In April 1995 a
settlement was reached with the remaining insurance companies and a payment of
$4,200,000 was subsequently received. In May 1995 agreements in principle were
reached with two Argentine companies to settle the litigation related to the
1992 auction sale of the Company's Argentine subsidiary. Payments totaling
$2,500,000 were received. In addition, in July 1995, a settlement was reached in
the railroad crosstie litigation against Northeast Cement Company and its
affiliates, which resulted, in August 1995, in a net payment to Rosebud of
$9,402,000.
 
     In 1995, Rosebud made total principal payments of $102,000,000 and total
interest payments of $10,825,000. An additional interest payment of $209,000 was
made in January 1996. Total principal and interest payments made through
December 31, 1995 were $150,457,000. In January 1996, Rosebud sold surplus
property in Washington for cash proceeds of $1,358,000.
 
     Cash generated by Rosebud in excess of the remaining face value of the
asset proceeds notes, accrued interest and Rosebud working capital requirements,
if any, will be paid to Lone Star.

27. ENVIRONMENTAL MATTERS
 
     The Company is subject to extensive, stringent and complex federal, state
and local laws, regulations and ordinances pertaining to the quality and the
protection of the environment and human health and safety, requiring the Company
to devote substantial time and resources in an effort to maintain continued
compliance. Many of the laws and regulations apply to the Company's former
activities, properties and facilities as well as its current operations. Changes
to such regulations or the enactment of new regulations in the future could
require the Company to undertake capital improvement projects or to cease or
curtail certain current operations or could otherwise substantially increase the
capital, operating and other costs associated with compliance. Moreover, there
can be no assurances that judicial or administrative proceedings, seeking
penalties or injunctive relief, will not be brought against the Company for
alleged non-compliance with applicable environmental laws and regulations
relating to matters as to which the Company is currently unaware. In addition,
if releases of hazardous substances are discovered to have occurred at
facilities currently or previously owned or operated by the Company, or at
facilities to which the Company has sent waste materials, the Company may be
subject to liability for the investigation and remediation of such sites.
 
     Cement kiln dust ("CKD"), a by-product of cement manufacturing, is
currently exempted from regulation as a hazardous waste pursuant to the Bevill
Amendment to the Resource Conservation and Recovery Act ("RCRA"). However, on
January 31, 1995 the Environmental Protection Agency ("EPA") issued a regulatory
determination regarding the need for regulatory controls on the management,
handling and disposal of CKD. Generally, the EPA regulatory determination
provides that the EPA intends to draft and promulgate regulations imposing
controls on the management, handling and disposal of CKD that will be based
largely on selected components of the existing RCRA hazardous waste regulatory
program, tailored to address the specific regulatory concerns posed by CKD. The
EPA regulatory determination further provides that new CKD regulations will be
designed both to be protective of the environment and to minimize the burden on
cement manufacturers. In early 1996, EPA officials reported that certain other
alternatives -- such as oversight of CKD management by state environmental
agencies -- also are being explored. It is not possible to predict at this time
what, if any, new regulatory controls on the management, handling and disposal
of CKD or what increased costs (or range of costs), if any, would be incurred by
the Company to comply with these requirements. As an alternative to new EPA
regulations or state oversight, portland cement manufacturers, including Lone
Star, are engaged in negotiations with the EPA in an attempt to enter into other
arrangements relating to the management of CKD.
 
     On July 20, 1995, the State of Indiana made a determination that the CKD
stored at the Company's Greencastle plant is a type I waste and requested that
the Company apply for a formal permit for an on-site landfill for the CKD. The
Company understands that similar notices were sent to other cement manufacturers
in the State of Indiana. The Company is protesting this determination through
legal channels and has received a stay to allow it to demonstrate that current
management practices pose no threat to the environment. The Company believes
that the State's determination ultimately will be reversed or the Company will
receive the needed permit or other adequate relief, such as an agreed order
requiring certain additional waste management procedures that are less stringent
than those required for type I wastes. If the Company is not successful in this
regard, however, like other Indiana cement producers, the Greencastle plant
could incur substantially increased operating and capital costs.
 
     The Cape Girardeau, Missouri and Greencastle, Indiana plants, which are the
Company's two cement manufacturing facilities using hazardous waste fuels
("HWF") as a cost saving energy source, are subject to strict federal, state and
local requirements governing hazardous waste treatment, storage and disposal
facilities, including those contained in the Boiler and Industrial Furnace
Regulations promulgated under RCRA (the "BIF Rules"). These facilities qualified
for and operate under interim status pursuant to RCRA and the BIF Rules. While
Lone Star believes that it is currently in compliance with the extensive and
complex technical requirements of the BIF Rules, in the past Lone Star has been
involved in certain environmental enforcement proceedings seeking civil
penalties and injunctive relief for past noncompliance, and there can be no
assurances that the Company will be able to maintain compliance with the BIF
Rules or that changes to such rules or their interpretation by the relevant
agencies or courts might not make it more difficult or cost prohibitive to
continue to burn HWF. As a result of a court decision vacating a BIF Rules air
emission standard, the

Company temporarily curtailed its use of HWF at the Greencastle plant. The
Company completed compliance testing in August 1995, has recertified under
interim status and has commenced burning HWF.
 
     The Company is currently engaged in the process of securing the permit
required under RCRA and the BIF Rules for the Cape Girardeau plant. The Company
anticipates that the Greencastle plant also will go through this permitting
process in late 1996. These permits are a requirement to enable Lone Star to
continue the use of HWF at those facilities. The permitting process is lengthy
and complex, involving the submission of extensive technical data. There can be
no assurances that the Company will be successful in securing a final RCRA
permit for either or both of its HWF facilities. In addition, if received, the
permits could contain terms and conditions with which the Company cannot comply
or could require the Company to install and operate costly control technology
equipment.
 
     Since 1991, federal and state environmental agencies have conducted
inspections and instituted inquiries and administrative actions regarding waste
fuel operations at both of the Company's cement manufacturing facilities which
burn HWF. In the first half of 1994 the Company paid amounts totaling
approximately $402,000 representing negotiated settlements with federal and
state environmental entities of administrative actions that alleged violations
of regulations pertaining to the handling and burning of HWF at the Greencastle
plant. In March 1994, the EPA instituted an administrative proceeding regarding
waste fuel operations at the Company's Cape Girardeau plant, seeking over
$500,000 in civil penalties. The Company negotiated a settlement with the EPA
which requires the payment by the Company of a civil penalty of approximately
$200,000, approximately $87,000 of which was offset by two supplemental
environmental projects completed in 1995.
 
     Lone Star was given official notices by the EPA that it intended to pursue
a civil penalty action for alleged regulatory violations at the Cape Girardeau
facility with respect to the installation of a secondary crusher and the
replacement of screens in 1986 and 1987. The Company has negotiated a settlement
of this matter with the EPA which will involve the payment of $40,000 to the EPA
and the paving of certain roads at the facility to control fugitive dust at an
estimated cost of $150,000.
 
     The Texas Natural Resource Conservation Committee ("TNRCC") has issued a
notice of violations in respect of certain air permitting application matters at
the Company's Maryneal, Texas plant. The TNRCC has also investigated certain
solid waste and water matters, and has had two conferences with the Company
concerning all of these matters. The TNRCC has advised the Company that it will
propose formal enforcement action in respect of the Company's air permits, which
could include a penalty and injunctive relief, and will require certain
additional safeguards in respect of solid waste disposal. The Company does not
expect that these matters will have a material adverse affect on its Maryneal,
Texas operations.
 
     Past operations of the Company, certain of its subsidiaries, or its
predecessors have resulted in releases of hazardous substances at sites
currently or formerly owned by the Company and certain of its subsidiaries or
where waste materials generated by the Company have been disposed. CKD and other
materials were placed in depleted quarries and other locations for many years.
The Company has been named by the EPA as a potentially responsible party for the
investigation and remediation of several Superfund sites. Included are sites
located in: Utah (seven sites, including three National Priority List ("NPL")
sites which were settled during the bankruptcy proceedings as discussed below);
Illinois (one NPL site); Texas (two sites, including one NPL site); Missouri
(one NPL site); Washington (one NPL site); Minnesota (two NPL sites); Colorado
(one NPL site); Florida (five sites, including two related NPL sites and the two
non-NPL sites described below); California (one non-NPL site described below);
Pennsylvania (one NPL site); and Louisiana (one NPL site). Except for the
matters described below, available factual information indicates that the
Company's disposal of waste at these sites was small or non-existent, and the
Company may have certain defenses arising out of its reorganization. In certain
instances the Company has availed itself of settlement offers it has found
attractive. The Company is also reviewing certain of its inactive properties to
determine if any remedial action may be required at these sites.
 
     In July 1989, the Company was advised by the EPA, that it was a potentially
responsible person ("PRP") with respect to three adjoining sites in Salt Lake
City, Utah on which CKD and small amounts of chrome-containing kiln brick from
the Company's Utah cement plant had been deposited. In July 1990, the EPA and
the Utah Department of Health
 
                                       48
<PAGE>   51
 
                           LONE STAR INDUSTRIES, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
issued a record of decision selecting a remedial action calling for removal of
the CKD, over a period of time, to a location to be selected in the Salt Lake
City vicinity where an industrial type landfill would be constructed. The
Company settled this matter during its bankruptcy proceedings and has also
settled an action brought by the Company in United States District Court in Utah
seeking contribution from two other PRP's for their share of investigation and
cleanup costs of the sites. The settlement agreement relating to the
contribution claims are subject to the other PRP's reaching settlements with the
EPA, the negotiation of which is continuing.
 
     In the early 1970's, the Company acquired subsidiaries that conducted
woodtreating or wood-dipping operations at two sites in Florida. Contamination
from chemicals used in the woodtreating operations at these non-NPL sites have
been the subject of various proceedings by federal, state and local
environmental entities, as well as lawsuits involving private parties. The
Company has brought actions against its insurers in respect of defense and
cleanup costs at both sites.
 
     In 1992, an EPA approved cleanup of soils and water at a site in Dania,
Florida previously owned by Lone Star was completed. Lone Star has also agreed
with the State of Florida Department of Environmental Protection ("FDEP") to
undertake a monitoring program for the presence of pentachlorophenol ("PCP") in
the groundwater. The monitoring has shown the groundwater to be free of PCP, and
the FDEP has advised the Company that no further remediation or monitoring of
PCP will be required. However, traces of other elements have been noted, and
monitoring of these elements will continue. This site was transferred to Rosebud
in 1994 and sold by Rosebud in 1995. From the proceeds of the sale, $2,000,000
was placed in escrow to assure compliance with the Company's agreement with the
FDEP, and Rosebud is currently negotiating to receive the funds remaining in
this escrow.
 
     The Company completed certain cleanup of soils at a site in Dade County,
Florida in 1992 and agreed to undertake further groundwater investigation of the
site and, if necessary, soil remediation, groundwater treatment and ground water
monitoring programs all within a specified monetary cap of $2,000,000.
 
     At the time of the 1994 sale of its interest in the Santa Cruz cement
plant, Rosebud committed to regulatory authorities to undertake the closure of a
former waste landfill area at the plant site. The closure has been completed,
and postclosure monitoring of the site is the responsibility of the plant owner.
 
     The Company, along with numerous other parties, has been named a defendant
in a series of toxic tort lawsuits filed in a Texas state court commencing in
March 1994 in which multiple plaintiffs claim to have suffered injury from the
proximity of deposits of toxic wastes or substances at a site located near
Galveston, Texas. The toxic wastes or substances are alleged to have been
deposited at the site starting in the 1940's. The Company does not believe that
it has any responsibility for the site and intends to contest these lawsuits
vigorously. The Company's insurance carriers have been notified of the claims
but have denied coverage.
 
     The December 31, 1995 consolidated balance sheet includes accruals of
$6,900,000 which represent the Company's current estimate of its liability
related to future remediation costs at sites where known environmental
conditions exist. The Company believes these reserves to be adequate for known
environmental matters.
 
28. LITIGATION
 
     From time to time the Company is named as a defendant in lawsuits asserting
product liability for which the Company maintains insurance coverage. In late
1995 an office building in Boston, Massachusetts, constructed in 1983 using
concrete pilings produced by San-Vel Concrete Corporation ("San-Vel"), an
inactive Lone Star subsidiary, was demolished by order of the City of Boston
based upon an engineering report that the pilings were unreliable. The owner of
the demolished building has notified the Company, among others, that it intends
to hold responsible parties liable. At the request of the City of Boston,
San-Vel has provided a list of the approximate twenty-five other buildings built
in that City between 1980 and 1990 using San-Vel pilings. The City has
reportedly inspected these buildings visually, without noting any apparent
piling failure, although engineering studies are reportedly being conducted with
final results expected in mid-1996. The Company believes that the cement
component of the concrete used to produce the pilings in certain of these
buildings, including the demolished building, was produced by it at one of its
former cement plants. There has been no indication that the cement was
defective. The Company is conducting an investigation into these matters and
believes that

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
it has both insurance coverage and good defenses to any claim of liability that
may be asserted against it relating to the demolished building.

(1) Gross profit is net of depreciation expense relating to cost of sales of
    $23,107,000, $16,326,000 and $4,697,000 in the year ended December 31, 1995,
    the nine months ended December 31, 1994 and the three months ended March 31,
    1994, respectively.
 
(2) Earnings per share are computed independently for each of the quarters
    presented. Therefore, the sum of the quarterly earnings per share in 1994
    and 1995 does not equal the total computed for the year due primarily to the
    use of the modified treasury stock method throughout the two years except
    for the first quarter of 1995 in which the result was anti-dilutive.
 
(3) Earnings per share for the first quarter of 1994 are not meaningful due to
    reorganization and revaluation entries and the issuance of 12,000,000 shares
    of new common stock (See Note 23).
