      Cement Industry Overview


      Portland cement is the essential binding material used in making
      concrete, which is widely used in residential and non-residential
      construction and in public works and infrastructure projects.  Cement
      is sold primarily in bulk form to producers of ready-mix concrete and
      manufacturers of concrete products.

      Cement is made in a multi-stage process that begins with the
      crushing, grinding and mixing of calcium (usually in the form of
      quarried limestone), sand, alumina, iron oxide and other materials. 
      This raw materials mixture is then reacted in rotary kilns at
      extremely high temperatures.  The resulting marble-size pellet
      material (called "clinker") is cooled and ground with a small amount
      of gypsum to produce cement having the consistency of fine powder.

      There are two basic methods of clinker production.  The older "wet"
      process involves mixing the raw materials with water to form a slurry
      that is reacted in the kiln.  This process involves the use of a
      large amount of fuel, but enables the raw materials to be handled and
      mixed easily.  In the more fuel-efficient "dry" process, the
      slurrying step is eliminated and clinker is produced by reacting only
      the dry raw materials.  Even more fuel-efficient processes involve
      preheater and preheater/precalciner techniques that recycle excess
      heat from the kiln to either preheat or to enhance chemical reaction
      of the raw materials prior to their introduction into the kiln.  The
      company estimates that, in general, the energy consumed to produce
      cement from a dry process preheater/precalciner kiln is approximately
      40% less than a wet process kiln.  All the company's kilns use the
      dry process.

      According to the United States Bureau of Mines' current report, the
      average price of a ton of cement in 1992, F.O.B. the point of sale,
      was $48.86.  Cement markets tend to be regional because of the low
      price of cement relative to its weight, making cost of transportation
      an important factor in the industry.  The company estimates that the
      approximate distance that one ton of cement can be transported for
      the same relative cost is 500 miles by vessel, 60 miles by rail and
      20 miles by truck.  As a result, cement plants whose products can be
      transported only by truck or rail tend to serve relatively small
      geographic markets (typically not in excess of a 200 mile radius of
      the plant), while plants with access to water transportation are able
      to efficiently serve considerably larger geographic markets.  The
      market served by a cement plant may be extended through the use of
      distribution terminals to which cement is transferred in bulk and
      inventoried for sale to customers in surrounding areas.

      Demand

      Demand for cement is correlated to cyclical construction activity,
      which, in turn, is influenced largely by national and regional
      economic conditions, including (particularly in the case of
      residential construction) prevailing interest rates.  In addition,
      levels of government spending on infrastructure improvement affect
      cement consumption.  Demand for cement is also seasonal, particularly


                                         -1-

                                       PART I

      Item l.   Business (continued)

      in northern markets where inclement weather affects construction
      activity.  According to the Portland Cement Association ("PCA"),
      total annual cement consumption in the United States over the past 20
      years has ranged from a low of 65.5 million tons in 1982 to a high of
      94.2 million tons in 1994, generally corresponding to then prevailing
      economic conditions and construction activity.  Cement consumption in
      the United States in 1994 was 94.2 million tons, of which
      approximately 24% was used in residential construction, 29% in non-
      residential construction, and the remainder in public construction,
      such as infrastructure.

      The company believes increased government spending on infrastructure
      improvement would have a favorable impact on future cement demand
      from the residential construction and non-building construction
      sectors (predominantly infrastructure).  Enactment of the Intermodal
      Surface Transportation Efficiency Act of 1991, which authorized the
      appropriation of federal funds primarily for construction and
      improvement of highways, bridges and mass transit systems, reflected
      Congressional recognition of the need for national infrastructure
      repair and replacement.  Future demand for cement for infrastructure
      improvement will depend on the level of funding made available for
      such purpose by federal, state and local governments.

      Supply

      According to current statistics published by the PCA, United States
      clinker production capacity decreased from 91.1 million tons to 82.8
      million tons, or by approximately 9%, from 1975 to 1993.  Statistics
      published by the United States Bureau of Mines and the PCA indicate
      that from 1975 to 1993 the number of cement companies operating in
      the United States has dropped from 57 to 44, and in 1992 the 10
      largest of such companies accounted for approximately 61% of total
      United States production capacity for clinker.  Because of the extent
      of capital investment required and the long lead times associated
      with establishing new or re-opening closed facilities, the company
      does not expect that significant additional domestic cement
      production capacity will be added unless cement prices increase
      significantly on a sustained basis over current levels.

      Imports of cement and clinker, which have had the most impact on
      markets along coastal and southern border areas of the United States,
      with ripple effects elsewhere, have declined from a high of 19% of
      total United States consumption in 1987 to approximately 14% in 1994,
      according to the PCA.  Factors influencing this decline have included
      the effect of anti-dumping actions brought against several foreign
      importers, which resulted in the imposition of substantial duties on
      cement and clinker imports from various countries beginning in 1995,
      increases in foreign demand, rising ocean shipping rates, and the
      decline in the value of the United States dollar relative to other
      currencies.

      Cement production is capital-intensive and involves high fixed costs. 
      As a result, plant capacity utilization levels are an important
      measure of a plant's profitability, since incremental sales volumes
      tend to generate increasing profit margins.  The PCA has estimated
      that total United States cement plant capacity utilization was 94.6%
      for 1994, which is the highest level since the PCA began collecting
      such data in 1971.

      Price Trends

      Due to the lack of product differentiation, competition in the cement
      industry is based largely on price.  Service and location of plants
      and terminals are also competitive factors.  Prices at which cement
      has been sold in the United States over the past several years have
      remained in a narrow range.  Notwithstanding favorable construction
      activity during the 1980's, cement prices remained relatively low due
      to the impact of lower-priced imported cement.  Until 1994, United
      States cement prices remained flat due to the downturn in general
      economic conditions and consequent declines in construction activity. 
      However, gradual improvement in the United States economy, coupled
      with reduced domestic production capacity and significantly lower
      levels of imported cement, have led to supply and demand
      relationships more favorable to cement producers, resulting in
      increased cement prices.  In 1994, due to heavy demand coupled with
      limited domestic supply, the company was able to increase prices by
      13% over 1993 levels, with price increases of up to $5.00 per ton in
      most of our markets on April 1, 1994, and another increase up to
      $5.00 per ton on August 1, 1994 in our Southeastern markets.  The
      company expects these favorable market conditions to continue in 1995
      and have announced cement price increases of up to $8.00 per ton,
      effective April 1, 1995 in most of its markets.

      General
      
      The company produces and sells gray portland cement and masonry
      cement; and, through various wholly-owned subsidiaries, mines,
      processes and sells coarse aggregates (crushed stone), fine
      aggregates (aglime) and high calcium limestone products.  The company
      also provides construction services for highway safety.  The
      company's operations are conducted principally in the eastern half of
      the United States.  During the past five years, cement, aggregates
      and limestone, and highway safety operations accounted for
      approximately 70% to 79%, 15% to 20%, and generally less than 10%,
      respectively, of the company's consolidated net sales.  From 1990
      through 1994, Medusa's quarterly sales as a percentage of annual
      sales have ranged from 12% to 14% during the first quarter and from
      32% to 34% during the third quarter. 

      Construction activity surged ahead throughout 1994, in spite of
      concern over rising interest rates, led by the best year in housing
      starts since 1988.  As indicated, tight supply conditions along with
      record demand resulted in upward pricing and record profits.  The
      company expects the construction recovery to continue in 1995,
      highlighted by increases in public works and commercial activity. 
      Infrastructure construction and, to a lesser extent, commercial
      building, appears to be less sensitive to interest rates than
      housing, which provides less than a quarter of the company's sales
      volume. 

      In an effort to satisfy the strong product demand, our four cement
      plants achieved a 91.2% capacity utilization.  The company's focused
      business strategy, the principal elements of which are: a
      concentration on its core business, a constant drive to lower
      operating costs, centralization of pricing decisions and the 

                                         -3-

      Item l.   Business (continued)

      maintenance of a lean management organization, enable the company to
      position itself to capitalize upon these favorable market conditions. 
      In furtherance of that strategy, the company's planned capital
      program includes projects designed to incrementally increase plant
      production capacity by a total of 6-8% over the next three years.

      Cement Operations

      The company ranks eighth in capacity among all United States cement
      companies and fourth in capacity among those domestically owned.  The
      company's cement operations serve markets in portions of the Great
      Lakes, the Southeast and the Western Pennsylvania/Northeastern Ohio
      portions of the United States.

      Regional Markets

      Great Lakes.  The Great Lakes regional market, consisting of portions
      of Michigan, Wisconsin, Ohio, Illinois, Indiana and Ontario, is
      served by the company's Charlevoix plant and its distribution network
      of ten terminals, eight of which are water based.  Demand in the
      Great Lakes region has been steady, and virtually no new production
      capacity has been added in recent years.  Sales volume was down
      slightly from 1993 levels which benefitted from the additional
      business generated when other producers could not meet customer
      requirements due to the flooding in the Midwest. 

      Management believes that the Charlevoix plant is among the lowest
      cost cement production facilities in the Great Lakes region.  This is
      due to its use of a single modern preheater/precalciner kiln which
      provides significant energy savings over other dry and wet process
      kilns.  The layout of the plant also results in an efficient
      utilization of manpower.  Charlevoix's deep-water shipping location
      and water-based terminals enable 95% of cement produced to be shipped
      by water, the lowest cost method of long-distance distribution, via
      the Medusa Conquest or the Medusa Challenger.  These company owned
      vessels have a combined capacity of 20,000 tons.  The company has
      made substantial distribution improvements over the last few years
      beginning with the conversion of the company's cement barge, the
      Medusa Conquest, in 1987, and its subsequent modification to a more
      efficient tug/barge system in 1992.  This subsequent modification
      increased the utilization of the barge by enabling it to operate in
      inclement weather.  The company has also expanded its distribution
      system with the construction of the Toledo, Ohio terminal in 1985,
      the Owen Sound, Ontario terminal in 1991, and the doubling of the
      capacity of the Cleveland, Ohio terminal in 1992.  Unfortunately, the
      harshest winter in 15 years caused plant problems in February, 1994,
      which resulted in lost production and a substantial increase in
      repair and maintenance costs.

      For 1995, Charlevoix is implementing an artificial intelligence  kiln
      control system and an automated process control instrumentation
      system to enhance productivity and reduce operating costs.

      Southeast.  The company has two plants and nine terminals (excluding
      the Orlando, Florida facility closed in February, 1995) in the
      Southeast regional market: the Clinchfield, Georgia plant, acquired 

                                         -4-

                                       PART I

      Item l.   Business (continued)

      from Penn Dixie Corporation and extensively rebuilt in 1972, and the
      Demopolis, Alabama plant, built in 1977 and acquired from Lafarge
      Corporation in February 1993.  The Demopolis plant serves water-based
      terminals in Chattanooga, Tennessee and Decatur, Alabama with up to
      six river barges.  Together, the two plants also serve seven
      rail/truck terminals in Alabama, Florida and Georgia.  Since the
      plants are located 240 miles apart, a number of marketing and
      manufacturing synergies exist, including the ability to alternatively
      ship to seven terminals, to specialize in certain cement products and
      packaging, and to rationalize distribution in what are the two
      plants' overlapping markets.  While demand in markets of the
      Southeast region is growing, management believes that supply is
      declining due to a reduction of imports into neighboring markets.

      Largely because both the Demopolis and Clinchfield plants operate
      energy-efficient preheater kilns, management believes that they are
      among the lowest cost production facilities in the region.  In 1994,
      the Demopolis plant burned waste derived liquid fuel (WDLF) for 26%
      of its current fuel needs.  The Clinchfield plant burns waste whole
      tires as an alternative kiln fuel and has been able to reduce its
      coal usage by 6%.  The company improved its water-based distribution
      system by leasing two barges that allow for a reduction in "stand by"
      tug time costs.

      Western Pennsylvania/Northeastern Ohio.  The company's Wampum plant
      is located between Pittsburgh, Pennsylvania and Youngstown, Ohio,
      serving markets as far east in Pennsylvania as State College, as far
      south as Wheeling, West Virginia, and as far west in Ohio as
      Columbus.  While demand in this region continues to grow, supply has
      remained relatively constant, with no new plants or major capacity
      expansions having occurred in the last five years or expected by
      management in the foreseeable future.

      Management believes that the Wampum plant's three dry kilns give it
      an operating cost advantage over its wet process competitors in the
      region.  The Wampum plant also had the advantage in 1994 of obtaining
      about 32% of its coal needs from its nearby limestone quarry which
      contains coal reserves.  Since 1985, the Wampum plant has burned
      WDLF, supplying 39% of its fuel needs in 1994, up from 26% in 1993.
      The improvement over 1993 results from installing large mix tanks
      which provide for a more consistent quality and composition of WDLF
      entering the kiln.  The company erected at the Wampum limestone
      quarry a large (40-cubic yard) dragline, replacing two smaller less
      efficient units.  This $7.0 million capital improvement was placed in
      operation in April, 1994.

      Energy

      Cement manufacturing is an energy intensive process, using fuel to
      fire kilns and electricity to grind raw materials into kiln fuel and
      clinker into finished cement.  The company has been an innovator in
      burning alternative fuels, such as WDLF and whole tires at its plants
      as a coal replacement.  The company has entered into arrangements
      with independent contractors (which, in turn, contract with suppliers
      of alternative fuel) which allow the company to reduce its energy
      costs by receiving WDLF either at a profit through tipping fees or at

                                         -5-

                                       PART I

      Item l.   Business (continued)

      a nominal charge.  In 1985, at its Wampum cement plant, the company
      became one of the first such facilities to burn WDLF.  The company
      also burns WDLF at its Demopolis plant.  The favorable economics of
      burning WDLF are significantly influenced by the tipping fees, which
      have been declining, the cost of environmental regulation, which has
      been increasing and a small reduction in maximum clinker output when
      burning WDLF.  The company has burned whole tires at its Clinchfield
      plant since 1990.  The company also seeks to minimize its energy
      costs by running its grinding mills, whenever possible, during off
      peak demand periods.

      Customers and Marketing

      The company's cement operations have over 1500 customers which are
      primarily ready-mix concrete dealers.  No single customer accounts
      for more than 5% of total consolidated sales.  The company's
      marketing efforts are focused on maximizing profitability, rather
      than market share.  This sales strategy is facilitated by the
      company's policy that pricing decisions (including the decision
      whether to meet lower competitive prices) are made only in the
      company's Cleveland headquarters.  Further, decisions whether to
      extend credit are made centrally by financial management.  Sales
      personnel are critical in developing and maintaining relationships
      with, and providing technical assistance to, customers.  They also
      facilitate production planning by meeting with customers regularly to
      discuss future requirements.  

      Construction Aggregates

      Through a wholly-owned subsidiary, Medusa Aggregates Company, the
      company operates nine crushed stone plants in Bardstown, Butler,
      Bowling Green (two plants) and Hartford, Kentucky; Columbia,
      Missouri; Lenoir, North Carolina; and West Pittsburg, Pennsylvania. 
      The company also operates a sand and gravel plant at Edinburg,
      Pennsylvania.  These operations mine, crush, screen and sell various
      sizes of aggregates to the construction industry, primarily to road
      builders for use in asphalt and concrete paving, road and base
      material, drainage blankets, erosion control and assorted small-
      volume applications.  The company is a major supplier of these
      products in all of the markets in which it operates.  Management
      believes the company to be among the low-cost producers in its
      primary markets and that it has achieved this result through constant
      review of its competitive position and the installation of cost
      improving plant modifications.  The total capacity of the company's
      aggregates plants is approximately 3,400 tons per hour, or in excess
      of 5 million tons annually.  Approximately 11% of Medusa's total
      construction aggregates capacity is covered by mineral reserves of
      over 50 years, 20% is covered by reserves of from 25 to 50 years, 62%
      is covered by reserves from 10 to 25 years and 7% is covered by
      reserves under 10 years.  Most aggregates are generally sold within
      a radius of 25 miles of the plant and are shipped to customers
      primarily by truck.

      Industrial Materials

      Through a wholly-owned subsidiary, Thomasville Stone and Lime
      Company, the company mines and processes high calcium limestone from

                                         -6-

      an underground deposit possessing chemical purity and whiteness at 
      Thomasville, Pennsylvania.  Chemical grade limestone is used by
      customers to manufacture white cement, supply calcium for livestock
      and poultry feeds, and neutralize soil for more efficient crop 
      production.  White stone is pulverized to a fine powder and used in
      joint compound, caulk, carpet padding, floor tile and paper. 
      Chemical stone is packaged for lawn application and white stone is
      processed and packaged for use as a decorative mulch by homeowners
      and landscaped contractors.  Limestone which does not meet chemical
      and color specifications is reduced to powder and used as a filler by
      manufacturers of asphalt shingles.  Industrial minerals are marketed
      primarily in the mid-Atlantic states.  Thomasville now has 14 product
      lines serving over 30 specialized agricultural, white cement, home
      improvement, consumer products and environmental markets.

      Highway Safety Construction

      The James H. Drew Corporation, a wholly-owned subsidiary of the
      company, installs highway safety systems such as guardrail, traffic 
      signals, signs, highway lighting and raised pavement markers. 
      Although Drew functions primarily as a subcontractor to paving and
      bridge contractors, approximately 30% of its work is bid directly to
      state highway departments and municipalities.

      Competition

      Generally, market conditions in the cement and construction
      aggregates industry are cyclical and highly price-competitive. 
      Because there is generally no product differentiation, these products
      are marketed as commodities, with price the principal method of
      competition.  To some extent, factors other than price, such as
      service, delivery time and proximity to the customer are
      competitively important.  The number and size of the company's
      competitors differ from market area to market area.  The company
      estimates that it competes with 28 cement manufacturers in its
      overall market areas and between 5 and 10 producers within each sales
      region.  Competitors include domestic and foreign producers and
      importers.  Because cement has a low value-to-weight ratio, cement
      companies with access to water-based transportation have a
      significant advantage in shipping over land-locked plants and
      terminals.

      Short-Term Borrowings

      During 1994, the company had no short-term borrowings.  In the years
      1993 and 1992, short-term borrowings' weighted average interest rates
      were 5.08% and 5.75%, respectively.

      Capital Expenditures

      In 1994, Medusa's capital expenditures were approximately $12.0
      million in its cement operations and $2.1 million in its aggregates
      operations.  For 1993, Medusa's capital expenditures were
      approximately $12.8 million in its cement operations and $1.8 million
      in its aggregates operations.

      Backlog

      Backlog for Medusa and its subsidiaries totaled approximately $10.5
      million as of December 31, 1994, compared with $14.2 million as of
      December 31, 1993.  Management does not believe that backlog is
      material to an understanding of Medusa's business, because long-term
      contracts generally comprise only a small portion of total sales. 

      Raw Materials

      The principal raw materials used by the company in the manufacture of
      cement are limestone or other calcareous materials, clay or shale,
      sand, iron ore, and gypsum.  Owned reserves of limestone and clay or
      shale are available at or near all of the company's cement plants,
      while other raw materials are readily available for local purchase by
      the company at all of its plant locations.  

      Employees

      As of December 31, 1994, the company had about 1,100 employees.  The
      company's business is seasonal and employment therefore declines from
      August 31 to December 31 of each year.  Most of the company's hourly
      employees in its cement operations are represented by different
      unions.  During 1994, the company entered into new four-year labor
      agreements with the local union of the United Cement, Lime, Gypsum
      and Allied Workers Division (International Brotherhood of
      Boilermakers, Iron Ship Builders, Blacksmiths, Forgers and Helpers,
      AFL-CIO) covering the cement workers at the Clinchfield and
      Charlevoix plants, expiring May 1, 1998.  Contracts with the local of
      the same national unions covering the hourly employees at the Wampum
      and Demopolis plants expire on May 1, 1996.  The company believes
      that relations with its employees are good.


      Environmental Matters

      Charlevoix Plant

      Fuel Release.  On June 21, 1991, the Company discovered and
      immediately filed a report with the Michigan Department of Natural
      Resources ("MDNR") relating to a release of #2 fuel oil which
      occurred on the property of the Charlevoix plant.  The matter was
      investigated both by the MDNR and the U.S. Environmental Protection
      Agency, Region 5 ("EPA"), and such investigations have been
      completed.  Under MDNR supervision, the Company immediately began to
      undertake preventive measures to preclude migration of the oil off
      the plant property or to surface water.  Available data indicate that
      these measures are working to preclude such migration.  Recently, the
      MDNR requested that the Company make a proposal for long-term
      remediation of the oil release.  The Company has retained
      environmental remediation consultants to conduct a study for review
      by the MDNR.  In December, 1993, the Company established on its books
      a contingent liability for $1.4 million, or $.06 per common share,
      for environmental remediation of the release of #2 fuel oil.  This
      charge represents the Company's current estimate of such remediation
      costs.  As additional information becomes available, changes in the

                                         -8-

                                       PART I

      Item l.   Business (continued)

      estimate of that liability may be required.  The Company is
      continuing to examine remediation alternatives at the site, none of
      which at this time are expected to have any material effect on the
      Company's financial condition, results of operations, or liquidity.

      Prevention of Significant Deterioration.  On September 8, 1994, the
      company received a Notice of Violation ("NOV") from the EPA.  The NOV
      alleged the company's Charlevoix, Michigan cement plant to be in
      violation of the Michigan State Implementation Plan and Part C of the
      federal Clean Air Act with respect to Prevention of Significant
      Deterioration ("PSD"), concerning sulphur dioxide ("SO2") emissions. 
      The company modified the Charlevoix plant in 1978 without filing for
      PSD review in reliance upon a consultant's advice that SO2 emissions
      would not increase.  Recent emissions tests, disclosed to the
      Michigan Department of Natural Resources ("MDNR") and the EPA,
      indicate that SO2 emissions did increase.  A study by an independent
      consultant demonstrates that the current SO2 emissions from the
      Charlevoix plant do not violate either the PSD increment or the
      National Ambient Air Quality Standard.  Therefore, neither the
      health, safety and welfare of the community nor the environment are
      impaired.  The company has filed for a revised air emissions permit
      and is cooperating with MDNR and EPA investigations. 

      Cement Kiln Dust.  On February 1, 1995, the EPA announced its
      decision to regulate Cement Kiln Dust ("CKD") as a hazardous waste
      under Subtitle C of the Resource Conservation and Recovery Act
      ("RCRA"), using tailored regulations site-specific to each U.S.
      cement plant.  CKD is a product of cement kilns which is collected in
      air emissions control devices (baghouses and electrostatic
      precipitators).  Previously, CKD had been exempt from regulation as
      a hazardous waste under an 1980 amendment to RCRA (the so-called
      "Bevill Amendment") as a high volume/low toxicity solid waste.  The
      cement industry, including the company, are preparing to offer a
      contract to EPA (on an individual company and cement plant site
      basis) which would be used in lieu of EPA-promulgated regulation to
      enforce certain voluntary CKD landfill disposal guidelines previously
      developed by the cement industry.  Until either the contract or the
      regulation becomes enforceable, CKD remains exempt from regulation as
      a hazardous waste under the Bevill Amendment.  While the disposal
      standards contained in the regulation/contract and the effective date
      of the regulation/contract remain uncertain, the company nontheless
      made a preliminary review to determine whether or not the
      regulation/contract is likely to have a material effect on the
      company's results of operations, financial condition or liquidity. 
      The company has preliminarily concluded that the CKD
      regulation/contract is unlikely to have a material effect on the
      operations of the company's Demopolis, Alabama, Clinchfield, Georgia
      and Wampum, Pennsylvania cement plants.  However, based upon the
      significant volume of CKD currently generated at the company's
      Charlevoix, Michigan cement plant and the characteristics of the
      local geology, the company cannot conclude, based upon its
      preliminary evaluation, whether or not the CKD regulation/contract is
      likely to have a material effect on Charlevoix plant operations. 
      Moreover, due to the size and importance of the Charlevoix plant to
      the company's overall operations, the company is currently unable to
      determine whether or not the CKD regulation/contract is likely to 

                                         -9-

      have a material effect on the company's results of operations,
      financial condition or liquidity.  The company has begun the process
      of evaluating raw material replacements at the Charlevoix plant which
      could reduce the generation of CKD.  The company is also cooperating
      with other members of the cement industry to seek a reversal of the
      EPA's February 1, 1995 action via judicial or legislative means.

      Item 2.    Properties

      Medusa's principal physical properties are utilized by its cement
      manufacturing operations. 

      These operations consist of four cement plants and a total of 20
      distribution terminals (excluding Orlando, Florida terminal closed
      February 1995).  All four of the company's plants are fully
      integrated, from limestone mining through bulk cement production, and
      all possess at least 50 years of limestone reserves.  The annual
      rated cement capacities of Medusa as of February 28, 1995 are shown
      in the following table:

      "Annual rated capacity" is defined as the annual output of cement
      theoretically to be achieved from full operation of a facility after
      giving consideration to such factors as down-time for regular
      maintenance, location and climatic conditions bearing upon the number
      of days per year during which the particular plant may be expected to
      operate, and actual historical performance.  Actual product mix may
      result in full utilization of a plant without realizing production
      equal to the "annual rated capacity".  Cement plant capacities are
      evaluated periodically taking into account actual experience in
      producing cement, plant modifications and innovations, and other
      factors.

      During 1995, the company plans on demolishing its wet process kiln at
      its Clinchfield plant.  This kiln has not been operated in over 10
      years.

      Medusa's cement plants, as a group, operated at 91.2% of annual rated
      clinker capacity in 1994 (89.9% in 1993).

      The Wampum and Clinchfield cement manufacturing plants are equipped
      to ship products by either rail or truck.  The Charlevoix plant can
      ship products by water or truck.  The Demopolis plant can ship
      products by water, rail or truck.  The plants are well maintained and
      in good operating condition.  There have been no physical changes in
      quarrying techniques over the past several years, nor is it
      anticipated that there will be any changes which would materially
      affect the cost of production.  All plants operate their own
      quarries, located adjacent to each of the plants.

      Antitrust Investigation

      On March 3, 1994, the Company received a Civil Investigative Demand
      ("CID") from the Atlanta, Georgia office of the U.S. Department of
      Justice, Antitrust Division.  The CID is apparently part of a
      nationwide investigation of what is believed to be virtually the
      entire domestic U.S. cement industry.  While the Company is not aware
      of the actual basis for the investigation, the notice which the
      Company received with the CID states that the investigation is "an
      Antitrust Division investigation into possible price fixing and
      market allocation by cement producers".  Medusa intends to cooperate
      fully with the investigation.
