                                     PART I
 
ITEM 1. BUSINESS
 
GENERAL
 
     CARBO Ceramics Inc. is the world's largest producer and supplier of ceramic
proppants for use in the hydraulic fracturing of natural gas and oil wells.
Demand for ceramic proppants depends generally upon the demand for natural gas
and oil and on the number of natural gas and oil wells drilled, completed or
recompleted worldwide. More specifically, the demand for ceramic proppants is
dependent on the number of oil and gas wells that are hydraulically fractured to
stimulate production.
 
     The hydraulic fracturing process consists of pumping fluids down a natural
gas or oil well at pressures and flow rates sufficient to split the hydrocarbon
bearing formation and create fractures in the formation. A granular material,
such as ceramic proppant or sand-based proppant, is suspended in the fluid and
packs the newly created fracture, keeping the fracture open once high-pressure
pumping stops. The proppant-filled fracture creates a permeable channel through
which the hydrocarbons can flow more freely from the formation to the well and
then to the surface.
 
     CARBO Ceramics was formed in 1987 for the purpose of purchasing the assets
of Standard Oil Proppants Company Ltd. (SOPCO). SOPCO was a joint venture formed
to operate the combined proppant businesses of the Carborundum Company and
Dresser Industries. These proppants businesses were started in 1978 and 1984
respectively. While the Carborundum Company and Dresser Industries had primarily
manufactured high strength, premium priced proppants for use in very deep wells,
CARBO Ceramics has pursued a strategy of introducing new, lower-priced,
lightweight, intermediate strength ceramic proppants to capture a greater
portion of the large market for sand-based proppants.
 
     The Company estimates that it supplies 60% of the ceramic proppants and 5%
of all proppants used worldwide.
 
PRODUCTS
 
     The Company's four product lines cover the entire spectrum of commercially
available ceramic proppants. CARBOHSP(TM) and CARBOPROP(R) are premium priced,
high strength proppants designed primarily for use in deep gas wells.
CARBOHSP(TM), which was introduced in 1979, is the original ceramic proppant,
formerly marketed as "Sintered Bauxite". CARBOHSP(TM) offers the highest level
of strength and conductivity for use primarily in deep gas wells. CARBOPROP(R),
which was introduced by the Company in 1982, is slightly lower in weight and
strength than CARBOHSP(TM) and was developed for use in deep gas wells that do
not require the strength of CARBOHSP(TM).
 
     The CARBOLITE(R) and CARBOECONOPROP(R) products are lightweight,
intermediate strength proppants designed for use in gas wells of moderate depth
and shallower oil wells. The products are manufactured and sold to compete
directly with sand-based proppants. CARBOLITE(R), introduced in 1984, is used in
medium depth oil and gas wells, where the additional strength of ceramic
proppants may not be essential, but where higher production rates can be
achieved due to the products' roundness and uniform grain size.
 
     CARBOECONOPROP(R), introduced in 1992 to compete directly with sand-based
proppants, is the Company's lowest priced and fastest growing product. The
introduction of CARBOECONOPROP(R) has resulted in ceramics being used in many
new markets by end users that had not previously used ceramic proppants. The
Company believes that many of the users of CARBOECONOPROP(R) had previously used
sand or resin-coated sand. The Company further believes that its ability to
continue to penetrate the market for sand-based proppants in 1997 was limited by
its production capacity for lightweight ceramic proppants.
 
CUSTOMERS AND MARKETING
 
     The Company's largest customers are, in alphabetical order, BJ Services
Company, Dowell and Halliburton Company, the three largest participants in the
worldwide petroleum pressure pumping industry.
 
                                        1
<PAGE>   3
 
These companies collectively accounted for approximately 84% of the Company's
1997 revenues. The Company's other customers include primarily foreign pumping
service companies, that compete in the worldwide fracturing business. The end
users of the Company's products, however, are the operators of natural gas and
oil wells that engage pumping service companies to hydraulically fracture wells
to improve the recovery of natural gas or oil wells, thereby enhancing the rate
of return on the investment made in such wells. The Company works with the
pressure pumping service companies to present the advantages of using ceramic
proppants to the operators of natural gas and oil wells. The Company generally
supplies its customers with products on a just-in-time basis, with transactions
governed by individual purchase orders. Continuing sales of product depend on
the Company's direct customers and the well operators being satisfied with both
product and delivery performance.
 
     The Company recognizes the importance of aggressive marketing when
introducing a technically advanced and performance enhancing, but intrinsically
more costly, product. The Company must market its products both to its direct
customers and to owners and operators of the natural gas and oil wells. The
Company's sales and marketing staff regularly calls on and keeps close contact
with the people who are influential in the proppant purchasing decision:
production companies, regional offices of well service companies that offer
pressure pumping services, and various completion engineering consultants. The
Company provides a variety of technical support services and has developed
computer software that models the return on investment achievable by using the
Company's ceramic proppants versus that of other proppants in the hydraulic
fracturing of a natural gas or oil well.
 
     The Company's Vice President of Marketing and Technology coordinates
worldwide sales and marketing activities. The Company's export marketing efforts
are conducted through its sales office in Aberdeen, Scotland and through two
commissioned sales agents located in South America and Australia.
 
     The Company's ceramic proppants are used worldwide by U.S. customers
operating abroad and by foreign customers. Sales outside the United States
accounted for 37%, 31% and 37% of the Company's sales for 1995, 1996 and 1997,
respectively.
 
     The distribution of the Company's export and domestic revenues is shown
below, based upon the region in which proppants were used by the customer:

COMPETITION AND MARKET SHARE
 
     The Company's chief worldwide competitor is Norton-Alcoa Proppants
("Norton-Alcoa"). Norton-Alcoa is a joint venture of Compagnie de Saint-Gobain,
a French glass and materials company, and Aluminum Company of America.
Norton-Alcoa manufactures ceramic proppants that directly compete with each of
the Company's products. In addition, Mineraco Curimbaba ("Curimbaba"), based in
Brazil, manufactures a sintered bauxite product similar to the Company's
CARBOHSP(TM), which is marketed in the United States under the name
"Sinterball". The Company believes that Curimbaba has not expanded its U.S.
product line to include a full range of ceramic proppants and is unlikely to do
so in light of patents held by the Company and Norton-Alcoa. The Company
believes that it supplies approximately 60% of the ceramic proppants and
approximately 5% of all proppants used by the oilfield services companies that
perform fracturing services worldwide.
 
     Competition for CARBOHSP(TM) and CARBOPROP(R) includes ceramic proppants
manufactured by Norton-Alcoa and Curimbaba. The Company's CARBOLITE(R) and
CARBOECONOPROP(R) products compete with ceramic proppants produced by
Norton-Alcoa and with sand-based proppants for use in the hydraulic fracturing
of medium depth natural gas and oil wells. The leading suppliers of mined sand
are
                                        2
<PAGE>   4
 
Unimin Corp., Badger Mining Corp., Wedron Silica Co., Ogelbay-Norton Company and
Colorado Silica Sand, Inc. The leading suppliers of resin-coated sand are Borden
Proppants Corp. and Santrol, a subsidiary of Fairmont Minerals Limited, Inc.
 
     The Company believes that the most significant factors that influence a
customer's decision to purchase the Company's products are: (i)
price/performance ratio, (ii) on-time delivery performance, (iii) technical
support and (iv) proppant availability. The Company believes that its products
are competitively priced and that its delivery performance is excellent. The
Company also believes that its superior technical support has enabled it to
persuade customers to use ceramic proppants in an increasingly broad range of
applications and thus increased the overall market for the Company's products.
 
     Prior to 1997, the Company had generally maintained sufficient inventory to
satisfy demand for its products. However, in 1997, it became obvious to the
management of the Company that previous capacity additions were insufficient to
satisfy demand in an improving market. The Company has addressed this issue
through the construction of a new manufacturing facility in McIntyre, Georgia
which is scheduled for completion in the fourth quarter of 1998.
 
     The Company continually conducts testing and development activities with
respect to alternative raw materials to be used in the Company's existing
production methods and alternative production methods. The Company is not aware
of the development of alternative products for use as proppants in the hydraulic
fracturing process. The Company believes that the main barriers to entry for
additional competitors are the patent rights held by the Company and certain of
its current competitors and the capital costs involved in building production
facilities of sufficient size to be operated efficiently.
 
DISTRIBUTION
 
     The Company maintains finished goods inventories at its plants in New
Iberia, Louisiana, and Eufaula, Alabama, and at six remote stocking facilities
located in: Rock Springs, Wyoming; Oklahoma City, Oklahoma; San Antonio, Texas;
Fairbanks, Alaska; Edmonton, Alberta, Canada; and Rotterdam, The Netherlands.
The remote stocking facilities consist of bulk storage silos with truck trailer
loading facilities. The Company owns the facilities in San Antonio, Rock Springs
and Edmonton and subcontracts the operation of the facilities and transportation
to a local trucking company. The remaining stocking facilities are owned and
operated by local trucking companies under contract with the Company. The North
American sites are supplied by rail, and the site in the Netherlands is supplied
by container ship. In total, the Company leases 79 rails cars, and owns or
leases 62 dedicated trailers. The price of the Company's products sold for
delivery in the lower 48 United States and Canada includes just-in-time delivery
of proppants to the operator's well site, which eliminates the need for
customers to maintain an inventory of ceramic proppants.
 
     The Company increased storage capacity at its remote storage facilities in
San Antonio, Rock Springs and Edmonton in 1997 at a cost of approximately $4.1
million.
 
RAW MATERIALS
 
     Ceramic proppants are made from alumina-bearing ores (commonly referred to
as bauxite, bauxitic clay or kaolin, depending on the alumina content), which
are readily available on the world market. Bauxite is largely used in the
production of aluminum metal, refractory material and abrasives. The main
deposits of alumina-bearing ores in the United States are in Arkansas, Alabama
and Georgia; other economically mineable deposits are located in Australia,
China, Jamaica, Russia and Surinam.
 
     The Company's New Iberia facility currently uses bauxite imported from
Australia and bauxitic clay mined in Arkansas. The Company has decreased its
dependence on imported bauxite and bauxitic clay as it has entered into a
long-term contract for the processing and supply of Arkansas bauxite and
bauxitic clay for use at the New Iberia facility. The Company believes that this
agreement, which stipulates a fixed price, subject to annual upward adjustments
in accordance with a producer price index, will provide a sufficient supply of
bauxite and bauxitic clay to meet the requirements of the New Iberia facility
through 1999.
 
                                        3
<PAGE>   5
 
     The Company's Eufaula facility exclusively employs locally mined uncalcined
kaolin, and the Company has entered into a contract requiring the supplier to
sell to the Company up to 200,000 net tons of kaolin per year and the Company to
purchase from the supplier 80% of the Eufaula facility's annual kaolin
requirements, each through 2003. This agreement stipulates a fixed price,
subject to annual adjustment in accordance with fluctuations (within an 8%
annual limit) in the producer price index. Raw material costs for the Eufaula
facility are substantially below those for the New Iberia plant, due to the
Eufaula facility's proximity to raw material reserves and use of uncalcined raw
materials.
 
     The new production facility in McIntyre, Georgia will also utilize
primarily locally mined uncalcined kaolin. The Company has entered into a
long-term supply agreement for these raw materials which stipulates a fixed
price subject to annual adjustments for changes in the producer price index and
fuel costs. The supply contract provides for a twenty-year supply of raw
materials.
 
PRODUCTION PROCESS
 
     Ceramic proppants are made by grinding or dispersing ore to a fine powder,
combining the powder into small, green (i.e., unfired) pellets and sintering the
pellets at 2,500F to 3,000F in a rotary kiln.
 
     The Company uses two different methods to produce ceramic proppants. The
Company's plant in New Iberia, Louisiana, uses a dry process (the "Dry Process")
which starts with bauxite or bauxitic clay which has been dried to remove both
free water and water which was chemically bound within the ore. This drying
process is referred to as calcining. The calcined ores are received at the plant
and ground into a dry powder. Pellets are formed by combining the powder with
water and binders and introducing the mixture into a high-shear mixer. The
process is completed once the green pellets are sintered in a rotary kiln. The
Company's competitors also use the Dry Process to produce ceramic proppants.
 
     The Company's plant in Eufaula, Alabama, uses a wet process (the "Wet
Process"), which starts with moist, uncalcined kaolin from local mines. The
kaolin is dispersed with chemicals in a water slurry. With an atomizer, the
slurry is sprayed like a mist into a dryer which causes the slurry to harden
into green pellets. Finally, these green pellets are sintered in rotary kilns.
The Company believes that the Wet Process is unique to its plant in Eufaula,
Alabama.
 
     The Company's plant in McIntrye, Georgia will use the Dry Process. However,
the Company expects to maintain lower production costs at this facility by
purchasing locally mined ore and performing the calcining process itself.
 
PATENT PROTECTION
 
     The Company's ceramic proppants are made by processes and techniques that
involve a high degree of proprietary technology, some of which is protected by
patents.
 
     The Company owns outright six issued U.S. patents and seven issued foreign
patents; three of these U.S. patents and four of these foreign patents relate to
the CARBOPROP(R) product produced by the Dry Process.
 
     The Company jointly owns with A/S NIRO Atomizer ("NIRO"), the Danish
designer and manufacturer of the spray atomizer device used in the Wet Process,
three issued U.S. patents and 17 issued foreign patents. The patents owned
jointly with NIRO generally relate to the Wet Process, and the products produced
thereby (CARBOLITE(R) and CARBOECONOPROP(R)).
 
     The current versions of the Company's six most important U.S. patents
expire at various times in the years 2002 through 2009 with its two key product
patents expiring in 2006 and 2009. The Company believes that these patents have
been and will continue to be important in enabling the Company to compete in the
market to supply proppants to the natural gas and oil industry. The Company
intends to enforce and has in the past vigorously enforced its patents. The
Company may be involved from time to time in the future, as it has been in the
past, in litigation to determine the enforceability, scope and validity of its
patent rights. Past disputes with its main competitor have been resolved in ways
that permit the Company to continue to benefit fully from its patent rights. The
Company and this competitor have cross-licensed certain of their respective
 
                                        4
<PAGE>   6
 
patents relating to intermediate and low density proppants on both a
royalty-free and royalty-bearing basis. (Royalties under these licenses are not
material to the Company's financial results.) The Company and NIRO have not
granted any licenses to third parties relating to the use of the Wet Process. As
a result of these cross licensing arrangements, both the Company and its main
competitor are able to produce a broad range of ceramic proppants, while third
parties are unlikely to be able to enter the ceramic proppants market without
infringing on the patent rights held by the Company, its main competitor or
both.
 
PRODUCTION CAPACITY
 
     The Company believes that constructing adequate capacity ahead of demand
while incorporating new technology to reduce manufacturing costs are important
competitive strategies to increase its overall share of the market for
proppants. Prior to 1993, the Company's production capacity was substantially in
excess of its sales requirements. Since that time, however, the Company has been
expanding its capacity in order to meet the generally increasing demand for its
products. In October 1993, the Company increased the capacity of the Eufaula
facility from 90 million pounds per year to 170 million pounds per year, in
response to the increasing demand for the Company's CARBOLITE(R) and
CARBOECONOPROP(R) products. In May 1995, the Company completed a 40 million
pound per year capacity expansion at the New Iberia facility, intended to meet
increasing demand for CARBOHSP(TM) and CARBOPROP(R). Most recently, in February
1996, the Company commenced operations of its second 80 million pound per year
expansion of the Eufaula plant. Total annual capacity is currently 100 million
pounds at the New Iberia facility and is 250 million pounds at the Eufaula
facility.
 
     In July 1997, the Company began construction of a new $40 million
manufacturing facility in McIntyre, Georgia. The plant is expected to be
completed in the fourth quarter of 1998 and is expected to have initial capacity
of 200 million pounds per year. The plant will be capable of producing all of
the Company's product lines and has been designed to be expandable to a capacity
of 400 million pounds per year.
 
     The following table sets forth the date of construction of and recent
expansion of the Company's manufacturing facilities:

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
GENERAL BUSINESS CONDITIONS
 
     CARBO Ceramics Inc. manufactures and sells ceramic proppants for use in the
hydraulic fracturing of oil and natural gas wells. Hydraulic fracturing is the
most common technique used to stimulate production from hydrocarbon bearing
formations. The process involves pumping fluids into an oil or gas well at very
high pressure in order to fracture the rock formation that contains the
hydrocarbons. As the fracture is created, the fluids are blended with granular
materials, or proppants, which fill the fracture and prop it open after the
pressure pumping ceases. The proppant filled fracture creates a highly permeable
channel that enables the oil or gas to flow more freely from the formation,
thereby increasing production from the well.
 
     Ceramic proppants are premium products that are sold at higher prices than
sand or resin-coated sand, the two primary alternative proppants. The principal
advantage of ceramic proppants is that they are stronger than sand-based
proppants. The higher strength of ceramic proppants results in higher production
rates in deep wells where sand or resin-coated sand may crush under high closure
stress. Consequently, the Company's business is influenced by the level of deep
drilling activity (generally defined as wells deeper than 7,500 feet). Ceramic
proppants are also more uniform in size and shape than sand-based proppants.
This uniformity can result in higher production rates than sand-based proppants
when used in wells that do not otherwise need ceramics for their higher
strength.
 
     As deep drilling, particularly in North America, is typically focused on
the production of natural gas, the Company's business is significantly impacted
by the number of natural gas wells drilled in North America. In markets outside
North America, sales of the Company's products are less dependent on natural gas
markets but are influenced by the overall level of drilling activity.
Furthermore, because the decision to use ceramic proppants is based on the
present value economics of comparing the higher cost of ceramic proppants to the
future value derived from increased production rates, the Company's business is
secondarily influenced by the price of natural gas and oil.
 
     From 1987 through 1996, the Company's revenues grew at a compound annual
rate of 21% despite relatively modest growth in the total number of gas wells
drilled. In 1997, the most active year for drilling activity in the last decade,
the Company's revenues increased by over 30% from 1996.
 
     From 1986 through 1996, the ceramic proppant industry has had productive
capacity in excess of demand. The competitive pressure brought on by this excess
capacity made it difficult for the Company to raise prices on its products.
However, the Company continued to grow its revenues through the introduction of
CARBOECONOPROP(R), a new product introduced in 1992, aimed at increasing the use
of ceramic proppants in the fracturing of medium depth wells, which had
previously been fractured with sand-based proppants. CARBOECONOPROP(R) has been
widely accepted in the industry and has been the Company's fastest
 
                                        9
<PAGE>   11
 
growing product line over the past five years. The Company expects that
CARBOECONOPROP(R) will continue to be the fastest growing product line in the
future and, as a result, gross profit margins will decline slightly.
 
     In the latter half of 1996, the industry began to operate near full
capacity and product availability on certain product lines was limited. In 1997,
demand for ceramic proppants continued to increase and availability of all
products was limited. In light of this fact, the Company raised prices on its
products by an average of 5% effective in the first quarter 1997. This price
increase was the first across-the-board price increase that the Company had
realized since 1991.
 
     Future growth in the Company's revenues and net income are dependent on the
future demand for natural gas in North America and the demand for hydrocarbons
worldwide. Management believes that the demand for natural gas will continue to
increase due to the abundance, relatively low cost and environmental benefits of
natural gas as a source of energy. With this in mind, the Company initiated
construction of a new manufacturing facility in McIntyre, Georgia in July 1997.
The plant will cost approximately $40 million to construct and is expected to be
completed in the fourth quarter of 1998. Initial capacity of the plant is
expected to be 200 million pounds per year, an increase of 57% over current
manufacturing capacity.
 
IMPACT OF YEAR 2000
 
     The Company has developed a plan to modify its information technology to be
ready for the year 2000 and has begun converting critical data processing
systems. The Company currently expects the project to be substantially complete
by early 1999, to cost less than $100,000 and have no significant effect on
operations.

     CARBO Ceramics Inc.'s 1997 revenues of $85.1 million established a new
annual record for the Company and were 31% higher than revenues in 1996. While
sales volume increased 24% from 1996, revenues grew at a faster pace due to an
increase in the average selling price that was the result of a price increase of
approximately 5% which became effective in January 1997. Domestic volumes
increased 13% from 1996 as strong demand for natural gas resulted in a 30%
increase in drilling activity. Export volumes increased 51% as the Company's
products became more widely accepted in the international oil markets. The
fastest growing product during 1997 was CARBOLITE(R), which increased 47% from
1996. The largest part of this increase was in export sales, to Russia,
Australia and the North Sea.
 
     Revenues were $65.2 million for the year ended December 31, 1996, an
increase of 12% over 1995 revenues of $58.0 million. While sales volume
increased 15% from 1995, revenues grew at a slower pace because of a shift in
the product mix toward CARBOECONOPROP(R), the Company's lowest price product,
targeted at penetrating the market for sand and resin-coated sand. For the year
ended 1996, CARBOECONOPROP(R) accounted for 43% of the Company's total sales
volume, up from 40% in 1995. In addition, revenue growth lagged volume growth
due to lower pricing in Europe and South Texas, as the Company protected its
market share by matching lower prices established by its competitors.

expenses include raw materials, labor, utilities and repair and maintenance
supplies. Fixed manufacturing expenses include depreciation, property taxes on
production facilities, insurance and factory overhead.
 
     Gross profit for 1997 increased $12.3 million or 40% from 1996. Gross
profit as a percentage of revenues increased from 47% to 50% due to the higher
average selling price resulting from the 5% price increase which became
effective in January 1997 and lower manufacturing costs in the New Iberia
manufacturing facility. The lower costs achieved in New Iberia were primarily
the result of improved efficiency due to increased production at the plant
versus the previous year. Production volumes also increased at the Eufaula
manufacturing facility due to a mid-year capacity expansion project but this was
offset by higher raw material prices resulting from a consolidation of suppliers
in the Eufaula area.
 
     Gross profit for 1996 increased by $1.9 million or 7% from 1995. Gross
profit as a percentage of revenues decreased from 49% to 47% due to lower
average selling prices for the Company's products and increases in raw materials
and labor. Raw material costs at the New Iberia facility increased due to an
increase in demand for CARBOHSP(TM) which requires a higher grade and higher
cost raw material to produce than CARBOPROP(R). Raw material costs at the
Eufaula facility increased due to the negotiation of a new supply contract that
was necessitated by a consolidation of suppliers in the Eufaula area.
Depreciation included in cost of goods sold increased by $788,000 from 1995 due
to the effect of the full year's depreciation on plant expansions completed
during 1995.

</TABLE>
 
     Selling, general and administrative expenses increased by $789,000 in 1997
over 1996. While SG&A expenses decreased as a percentage of revenues, there was
a substantial change in the composition of these expenses from 1996 to 1997. In
connection with the initial public offering of the Company's Common Stock in
1996, the vesting of restricted stock previously granted to the Company's
President and Chief Executive Officer was accelerated. This resulted in non-cash
compensation expense of $1,316,000 in 1996, where none was present in 1997.
These reductions in 1997 were partially offset by new costs incurred in
connection with regulatory filing costs, listing expenses and shareholder
communication costs associated with being a publicly traded company. Other SG&A
components that increased were those that vary with sales volume or
profitability including warehouse and shipping expenses, commissions expense and
incentive compensation.
 
     Selling, general and administrative expenses increased by $978,000 in 1996
over 1995. While SG&A expenses increased only slightly as a percentage of
revenues, there was a substantial change in the composition of these expenses in
1996. Prior to the initial public offering of the Company's Common Stock, a
consulting agreement with the Company's Chairman was terminated in April 1996.
As a result, expenses recognized in connection with the consulting agreement
decreased by $717,000 in 1996 as compared to 1995. In connection with the
initial public offering, the vesting of restricted stock previously granted to
the Company's President and Chief Executive Officer was accelerated. This
acceleration resulted in an incremental non-cash compensation expense of
$877,000 over 1995. Other increases in SG&A expenses in 1996 were variable
expenses that increased due to higher sales volume. These variable expenses
include warehouse charges, incentive compensation and franchise taxes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Cash and cash equivalents as of December 31, 1997 were $8.9 million
compared to $17.4 million at the beginning of the year. The Company generated
cash from operations of $23.6 million. Cash used in investing and financing
activities totaled $32.1 million. As of December 31, 1997 the Company held $13.9
million in investments expected to be held to maturity. These investments
consisted solely of U.S. Government Securities.
 
                                       11
<PAGE>   13
 
     Total capital expenditures for property, plant and equipment during 1997
were $13.8 million. Spending on the new Georgia manufacturing facility scheduled
to be completed by the 4th quarter of 1998 was $7.8 million, expansion of the
San Antonio storage facility -- $1.8 million, acquisition of Rock Springs
Terminal -- $1.3 million, Canadian remote storage expansion -- $1.1 million,
Eufaula capacity expansion and kiln shell replacement -- $1.3 million. The
balance of $.5 million was spent on the normal replacement of capital equipment.
Other investing activities during the year involved the purchase of $13.9
million of held-to-maturity investments (U.S. Government Securities).
 
     The Company paid $4.4 million in dividends during 1997.
 
     The Company plans to spend approximately $32 million for the completion of
its new manufacturing facility in McIntyre, Georgia during 1998, with funding
expected to be provided entirely by cash generated from operations. The
Company's current intention, subject to its financial condition, the amount of
funds generated from operations and the level of capital expenditures, is to
continue to pay quarterly dividends to shareholders of its Common Stock at the
rate of $0.075 per share.
 
     In 1997, the Company maintained an unsecured line of credit in the amount
of $9.0 million. As of December 31, 1997, there were no borrowings outstanding
under this credit agreement. An amended and restated credit agreement under
which the Company may borrow up to $10.0 million through December 31, 2000 was
executed on February 12, 1998.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
CARBO Ceramics Inc.
 
     We have audited the accompanying consolidated balance sheets of CARBO
Ceramics Inc. as of December 31, 1997 and 1996, and the related consolidated
statements of income, shareholders' equity, and cash flows for each of the three
years in the period ended December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of CARBO Ceramics
Inc. at December 31, 1997 and 1996, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF BUSINESS
 
     CARBO Ceramics Inc. (the "Company") was formed in 1987 and is a
manufacturer of ceramic proppants. The Company has production plants in New
Iberia, Louisiana and Eufaula, Alabama and primarily markets its proppant
products through pumping service companies that perform hydraulic fracturing for
major oil and gas companies.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of CARBO
Ceramics Inc. and its wholly owned subsidiary, CARBO Ceramics Sales Corporation.
CARBO Ceramics Sales Corporation was formed on July 31, 1996 under the laws of
Barbados. All significant intercompany transactions have been eliminated.
 
CONCENTRATION OF CREDIT RISK
 
     The Company performs periodic credit evaluations of its customers'
financial condition and generally does not require collateral. Receivables are
generally due within 30 days. The majority of the Company's receivables are from
customers in the petroleum pressure pumping industry. Credit losses historically
have been insignificant.
 
CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. The carrying amounts
reported in the balance sheet for cash equivalents approximate fair value.
 
INVESTMENT SECURITIES
 
     Management determines the appropriate classification of debt securities at
the time of purchase and reevaluates such designation as of each balance sheet
date. Debt securities are classified as held-to-maturity when the Company has
both the positive intent and ability to hold the securities to maturity.
Held-to-maturity securities are stated at amortized cost, adjusted for
amortization of premiums and accretion of discounts to maturity. At December 31,
1997, all investment securities were classified as held-to-maturity. The fair
value of the investments approximated the carrying value at December 31, 1997.
 
INVENTORIES
 
     Inventories are stated at the lower of cost (first-in, first-out method) or
market. Finished goods inventories include costs of materials, plant labor and
overhead incurred in the production of the Company's products.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment are stated at cost. Depreciation is computed
on the straight-line method for financial reporting purposes using the following
estimated useful lives:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
1. SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
INCOME TAXES
 
     Income taxes have been provided using the liability method in accordance
with FASB Statement No. 109, "Accounting for Income Taxes." Prior to April 24,
1996, the shareholders of the Company had elected S Corporation status under the
Internal Revenue Code and certain comparable state tax laws. As a result, the
Company's taxable income for federal and certain state jurisdictions where the
Company had significant operations was reported on the tax returns of its
shareholders.
 
EARNINGS PER SHARE
 
     In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings per Share." Statement No. 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted

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 those estimates.
 
2. BANK BORROWINGS
 
     The Company has a Secured Revolving Credit Agreement (the "Credit
Agreement") with a bank under which it may borrow up to $9.0 million at 0.5%
above the bank's Base Rate (as defined in the Credit Agreement) through January
31, 1998. The weighted-average interest rate on the Credit Agreement was 8.75%
for 1996. There were no borrowings against the line of credit in 1997. Under the
terms of the Credit Agreement, the Company is required to maintain certain bank
accounts with the lender, with balances equal to transactional and
investment-related charges. The terms of the Credit Agreement further provide
for certain affirmative and negative covenants, including a restriction on
capital expenditures.
 
3. LEASES
 
     The Company leases railroad equipment under operating leases. Minimum
future rental payments due under noncancelable operating leases with remaining
terms in excess of one year as of December 31, 1997 are as follows ($ in

                                                      ======
</TABLE>
 
     Leases generally provide for renewal options for periods from one to five
years at their fair rental value at the time of renewal. In the normal course of
business, operating leases are generally renewed or replaced by other leases.
Rent expense for all operating leases was $920,000 in 1997, $740,000 in 1996,
and $732,000 in 1995.

4. INCOME TAXES
 
     Since its formation through April 24, 1996, the Company elected to be
treated for federal and certain state income tax purposes as an S Corporation.
As a result, earnings of the Company have been taxed directly to the
shareholders of the Company rather than to the Company. Prior to the completion
of its initial public offering, the Company terminated its S Corporation
election and, accordingly, became subject to federal and state income taxes. The
deferred tax effects of the change in tax status increased net income for 1996
by $884,000. The Company also recorded a deferred tax asset of $3.5 million with
a corresponding increase in additional paid-in capital in 1996 related to the
vesting of 800,000 restricted shares of Common Stock held by the Company's Chief
Executive Officer upon the occurrence of the initial public offering. The
Company realized the full benefit of this deferred tax asset during 1996.
 
     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities as of December 31, 1997 and
1996 are as follows ($ in thousands):

5. SHAREHOLDERS' EQUITY
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share on all matters
to be voted on by shareholders and do not have cumulative voting rights. Subject
to preferences of any Preferred Stock that may be issued in the future, the
holders of Common Stock are entitled to receive ratably such dividends, if any,
as may be declared from time to time by the Board of Directors out of funds
legally available for that purpose. In the event of liquidation, dissolution or
winding up of the Company, the holders of Common Stock are entitled to share
ratably in all assets remaining after payment of liabilities, subject to prior
distribution rights of Preferred Stock, if any, then outstanding. The Common
Stock has no preemptive or conversion rights or other subscription rights. There
are no redemption or sinking fund provisions applicable to the Common Stock. All
outstanding shares of Common Stock are fully paid and nonassessable.
 
     Prior to 1996, the Company issued to its President and Chief Executive
Officer shares of Common Stock, pursuant to restricted stock agreements, as
compensation for future services. These shares had dividend rights; however,
sale of the shares was restricted prior to vesting which was subject to the
occurrence of certain events, including the initial public offering of the
Company's Common Stock. The restricted stock vested upon the occurrence of the
initial public offering on April 26, 1996 and the remaining balance of unearned
compensation was recorded as compensation expense. Compensation expense totaled
$1.3 million in 1996 and $438,000 in 1995.
 
     Prior to April 17, 1996, the Company's authorized capital stock consisted
of 20,000 shares of Common Stock, of which 6,001 shares were issued and
outstanding, and 2,000 shares of Class B Common Stock, of which 150 shares were
issued and outstanding. On April 17, 1996, the Company (i) caused the conversion
of all issued and outstanding shares of its Class B Common Stock into shares of
Common Stock, and (ii) effected a 2,000 for 1 split of the Common Stock. All
capital amounts, share and per share data in the accompanying financial
statements have been retroactively restated, where appropriate, to reflect the
stock split.
 
     On January 14, 1998, the Board of Directors declared a cash dividend of
$0.075 per share. The dividend is payable on February 15, 1998 to shareholders
of record on January 30, 1998.
 
PREFERRED STOCK
 
     The Company's charter authorizes the issuance of 5,000 shares of Preferred
Stock. The Board of Directors has the authority to issue the Preferred Stock in
one or more series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, conversion rights, voting
rights, terms of redemption, redemption prices, liquidation preferences and the
number of shares constituting any series or the designation of such series,
without further vote or action by the Company's shareholders. No shares of

Preferred Stock are currently outstanding, and the Company has no present plans
to issue any shares of Preferred Stock.
 
6. STOCK OPTION PLAN
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation" (Statement 123),
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB 25, because the exercise price of the
Company's employee stock options equals the market price of the underlying stock
on the date of grant, no compensation expense is recognized.
 
     The Company's 1996 Stock Option Plan for Key Employees (the "Option Plan")
has authorized the grant of options to purchase an aggregate of 1,000,000 shares
of the Company's Common Stock to certain officers and key employees of the
Company chosen by a committee appointed by the Board of Directors (the
"Compensation Committee") to administer such plan. Under the Option Plan, all
options granted have 10 year terms, and conditions relating to the vesting and
exercise of options are determined by the Compensation Committee for each
option. Options granted under the Option Plan are "nonstatutory options"
(options which do not afford income tax benefits to recipients, but the exercise
of which may provide tax deductions for the Company). Each option will have an
exercise price per share equal to the fair market value of a share of Common
Stock on the date of grant and no individual employee may be granted options to
purchase more than an aggregate of 500,000 shares of Common Stock. The options
vest annually over a four-year period.
 
     Pro forma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of that
statement. The fair value for these options was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions for 1997 and 1996, respectively: risk-free interest rates of 5.34%
and 6.19%; dividend yields of 1.0% and 1.5%; volatility factors of the expected
market price of the Company's Common Stock of .337 and .300; and a weighted
average expected life of the option of 5 years.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options (net of related expected tax benefits) is amortized to expense over the
options' vesting period. Since the Company's options generally vest over a
four-year period, the pro forma disclosures are not indicative of future amounts
until Statement 123 is

8. PRO FORMA NET INCOME
 
     Pro forma net income for 1996 and 1995 reflects a provision for income
taxes at an effective rate of approximately 37% to illustrate how historical net
income might have been affected if the Company had not been an S Corporation for
income tax purposes. The Company elected to be treated as an S Corporation
pursuant to the Internal Revenue Code from June 23, 1987 through April 23, 1996,
immediately after which it terminated its S Corporation election in conjunction
with the initial public offering. As a result, the Company was not subject to
federal income taxes during this period. By election of the shareholders, S
Corporation status was also applicable to the state jurisdictions where the
Company had significant operations.

<PAGE>   11
shall be in an amount not less than $100,000 or an integral multiple thereof,
except that an Advance may be in an amount equal to the entire unused
Commitment. Within the limits of the Commitment, the Borrower may borrow,
prepay pursuant to Section 2.08, and reborrow under this Section 2.01.

         SECTION 2.02.    Making the Advances.  Each Advance shall be made on
the same day the Borrower has given notice to the Lender, provided the Lender
has received such notice by 12:00 p.m. (New York City time) on such date. Such
notice shall be by telephone and shall be promptly confirmed by the Borrower in
writing. All such notices shall specify the date and amount thereof. Upon
fulfillment by the Borrower of the applicable conditions set forth in Article
III, the Lender will make such Advance available to the Borrower in immediately
available funds at the Lender's office at 59 Wall Street, New York, New York

         SECTION 2.03.    Commitment Fee.  The Borrower agrees to pay to the
Lender a commitment fee on the average daily unused portion of the Commitment
from the Closing Date until the Termination Date at the rate of three-eighths
(3/8) of one percent (1%) per annum, payable quarterly in arrears on the first
Business Day of each fiscal quarter of the Borrower for the immediately
preceding fiscal quarter of the Borrower in each year during such period,
commencing April 1, 1998, and ending on the Termination Date.

         SECTION 2.04.    Optional Termination of the Commitment.  The Borrower
shall have the right, upon (i) at least thirty (30) days' notice to the Lender
prior to the end of each fiscal quarter of the Borrower after the first
anniversary of the Closing Date, and (ii) full repayment of all sums, both
principal and accrued interest, then outstanding, to terminate the





                                       8
<PAGE>   12
Commitment in whole, but not in part. Simultaneously with any termination of
the Commitment under this Section, the Borrower shall pay to the Lender the
commitment fee earned through the Termination Date on the amount of the
Commitment so terminated.

         SECTION 2.05.    Selection of Interest Options.  Subject to Section
2.06, and provided that no Event of Default shall have occurred and is
continuing, the outstanding principal balance of each Advance shall bear
interest at the LIBOR Fixed Rate or the Base Rate, in accordance with the
following:

                 (a)      Interest on a Base Rate Advance.  A Base Rate Advance
         shall bear interest on the unpaid principal balance thereof, from time
         to time outstanding, at a fluctuating interest rate per annum which
         shall, from day to day, be equal to the lesser of either:  (1) the
         Base Rate; or (2) the Maximum Rate.  Each change in either the Base
         Rate or the Maximum Rate (or any component of the Base Rate or the
         Maximum Rate) as the case may be, shall become effective, without
         notice to the Borrower (which notice is hereby expressly waived by the
         Borrower), on the date of each change in either of such interest rates
         (or any component of any of such interest rates).

                 (b)      Interest on a LIBOR Rate Advance.  A LIBOR Rate
         Advance shall bear interest, during each LIBOR Interest Period
         applicable thereto, on the unpaid principal balance thereof, from time
         to time outstanding, at an interest rate per annum which shall, from
         day to day, be equal to the lesser of either:  (1) the applicable
         LIBOR Fixed Rate; or (2) the Maximum Rate.  Each change in the Maximum
         Rate or any component of the Maximum Rate, as the case may be, shall
         become effective, without notice to the





                                       9
<PAGE>   13
         Borrower (which notice is hereby expressly waived by the Borrower) on
         the date of each change in such interest rate or any component of such
         interest rate.

                 (c)      Advance Deemed To Be Base Rate Advance.  Unless the
         Borrower selects the LIBOR Fixed Rate as the Applicable Contract Rate
         with regard to an Advance, as provided for in this Article II, such
         Advance shall be deemed to be a Base Rate Advance for the purpose of
         computing interest thereon pursuant to this Agreement.

                 (d)      Interest Recoupment.  If, at any time, the Applicable
         Contract Rate then in effect shall exceed the Maximum Rate, thereby
         causing the Applicable Contract Rate to be limited to the Maximum
         Rate, any subsequent reductions in the Applicable Contract Rate shall
         not reduce the Applicable Contract Rate below the Maximum Rate until
         the total amount of interest accrued on the unpaid principal balance
         of the Advances from time to time outstanding during the term thereof,
         equals the amount of interest which would have accrued thereon if the
         various Applicable Contract Rates which are applicable to the unpaid
         principal balances of the Advances from time to time outstanding
         during the term of this Agreement, had at all times been in effect
         without the limitation of the Maximum Rate.

                 (e)      Final Interest Payment.  If on the date of the final
         payment of all Advances (whether on the Termination Date or
         otherwise), the total amount of interest actually paid, or accrued,
         under the provisions of the Loan Documents is less than the total
         amount of interest which would have accrued if the various Applicable
         Contract Rates had at all times been applicable to the principal
         balance of the Advances, from time to time





                                       10
<PAGE>   14
         outstanding, during the term of this Agreement, the Borrower agrees to
         pay, to the extent permitted by applicable law, to the Lender an
         amount equal to the difference between:  (1) the lesser of either (A)
         the amount of interest which would have accrued on the Advances if the
         Maximum Rate had at all times been in effect, or (B) the amount of
         interest which would have accrued on the Advances if the various
         Applicable Contract Rates had at all times been in effect without the
         limitation of the Maximum Rate; and (2) the amount of interest which
         has actually accrued or been paid on the Advances through the date of
         such final payment in accordance with the provisions of the Loan
         Documents.

                 (f)      Interest After Maturity of the Advances.  All
         delinquent payments of principal and/or interest on the Advances shall
         bear interest at a fluctuating rate per annum equal to the Base Rate
         plus four percent (4%) from the date due until paid.

                 (g)      Interest Payment Dates.  Interest on the aggregate
         principal balance of the Advances from time to time outstanding shall
         be payable as it accrues on each Interest Payment Date, beginning with
         the Interest Payment Date following the Closing Date, and continuing
         on each Interest Payment Date thereafter, until the maturity thereof.

                 (h)      Payment on Business Day.  If any payment of principal
         or interest to be made on the Advances shall become due on a day other
         than a Business Day, such payment may be made on the next succeeding
         Business Day (unless the result of such extension of time would be to
         extend the date for such payment into another calendar month, beyond
         the maturity date of the Advances or beyond the expiration of the
         applicable LIBOR Interest Period, in such event, said payment shall be
         made on the





                                       11
<PAGE>   15
         Business Day immediately preceding the day on which such payment would
         otherwise have been due) and such extension of time shall in such case
         be included in computing of interest, if any, in connection with such
         payment.

                 (i)      Additional Amounts Payable Upon Prepayments or Other
         Payments of LIBOR Rate Advances.  If any LIBOR Rate Advance is to be
         prepaid, or if the Borrower makes any principal payments with respect
         to any such LIBOR Rate Advance on any date other than the last day of
         the LIBOR Interest Period for such LIBOR Rate Advance, the Borrower
         shall reimburse the Lender, on demand, for all Consequential Loss and
         Increased Costs incurred by Lender, plus all accrued, but unpaid,
         interest on the amount so prepaid to such prepayment or payment date,
         together with any other amounts owing to the Lender in connection with
         such prepayment or payment pursuant to the terms of this Agreement or
         any of the other Loan Documents.  All prepayments (whether optional or
         otherwise) made pursuant to this Agreement shall be applied first to
         accrued, but unpaid, interest and then to principal.  A certificate of
         the Lender setting forth the amount of any such loss or cost shall, in
         the absence of manifest error or bad faith, be final, binding, and
         conclusive for all purposes.  Any conversion of any LIBOR Rate Advance
         to a Base Rate Advance on a day other than on the last day of the
         applicable LIBOR Interest Period shall be deemed a principal
         prepayment for the purpose of this Subsection 2.05(i).

                 SECTION 2.06     Interest Rate Options.

                 (a)      Interest Rate Options.  Subject to the provisions of
         this Section 2.06, and provided that no Event of Default has occurred
         and is continuing, the Borrower shall have





                                       12
<PAGE>   16
         the option of having an Advance bear interest at the Base Rate or the
         LIBOR Fixed Rate (an "Interest Rate Option"); provided, however, that
         (i) the Borrower may not have more than three (3) Interest Rate
         Options which select the LIBOR Fixed Rate for the Advances in effect
         at any one time and (ii) no Interest Rate Option which selects the
         LIBOR Fixed Rate for any portion of the Advances shall be for an
         amount less than the principal amount of $2,000,000 plus an integral
         multiple of $100,000.

                 (b)      Changes in Interest Rate Options.  Each change in
         Interest Rate Options made pursuant to this Section 2.06 shall, for
         all purposes of this Agreement, be deemed both a payment of the Base
         Rate Advance or LIBOR Rate Advance, whichever is applicable, from
         which such change was made and a borrowing (notwithstanding that the
         aggregate unpaid principal of the Advances is not thereby changed) of
         the Base Rate Advance or LIBOR Rate Advance, whichever is applicable,
         into which such Advance is converted.

                 (c)      Selection of Interest Rate Options.  The Borrower may
         select an Interest Rate Option by giving the Lender a Rollover Notice
         in accordance with the provisions of subsections (1) or (2) below, as
         applicable, which notice shall specify a LIBOR Interest Period;
         provided, however, that (i) any LIBOR Interest Period which would
         otherwise end on a day which is not a Business Day shall be extended
         to the next succeeding Business Day, unless the result of such
         extension would be to extend such LIBOR Interest Period into another
         calendar month, in which event such LIBOR Interest Period shall end on
         the immediately preceding Business Day; (ii) any LIBOR Interest Period
         that begins





                                       13
<PAGE>   17
         on the last Business Day of a calendar month shall end on the last
         Business Day of a calendar month; (iii) any LIBOR Interest Period
         which begins on a day for which there is no numerically corresponding
         day in the calendar month at the end of such LIBOR Interest Period
         shall end on the last Business Day of such calendar month; (iv) the
         length of each LIBOR Interest Period selected by the Borrower shall be
         irrevocable for the period so selected; and (v) no LIBOR Interest
         Period shall extend beyond the Termination Date.

                          (1)     Selection at Expiration of LIBOR Interest
                 Period. Before the termination of any LIBOR Interest Period,
                 and provided that no Event of Default has occurred and is
                 continuing, the Borrower shall give the Lender a Rollover
                 Notice specifying the Interest Rate Option which shall be
                 applicable to such LIBOR Rate Advance upon the expiration of
                 such LIBOR Interest Period.  Such Rollover Notice shall be
                 given to the Lender at least three (3) Business Days before
                 the termination of such LIBOR Interest Period.  If the
                 Borrower shall specify the LIBOR Fixed Rate, such Rollover
                 Notice shall also specify the length of the succeeding LIBOR
                 Interest Period selected by the Borrower.  Each Rollover
                 Notice shall be irrevocable and effective upon receipt thereof
                 by the Lender.  If the required Rollover Notice shall not have
                 been timely received by the Lender as herein provided before
                 expiration of the then relevant LIBOR Interest Period, the
                 applicable LIBOR Rate Advance shall be automatically converted
                 to a Base Rate Advance on the last day of the then current
                 LIBOR





                                       14
<PAGE>   18
                 Interest Period for such LIBOR Rate Advance.

                          (2)     Conversion Option.  With respect to Base Rate
                 Advances, and provided no Event of Default has occurred and is
                 continuing, the Borrower shall have the option ("Conversion
                 Option"), on any Business Day ("Conversion Date"), to convert
                 from the Base Rate to the LIBOR Fixed Rate by giving the
                 Lender a Rollover Notice specifying such Conversion Option at
                 least three (3) Business Days prior to such Conversion Date.

         SECTION 2.07     Special Provisions for LIBOR Rate Advances.

                 (a)      Unavailability, Illegality, or Inadequacy of the
         LIBOR Fixed Rate.  If at any time the Lender determines (which
         determination shall, for all purposes, be final, conclusive, and
         binding on the Borrower) that:  (1) the Lender is unable, or that it
         has become unlawful for the Lender to obtain, or cause to be obtained,
         funds in the London interbank market in order to make, fund, or
         maintain the principal balances of any LIBOR Rate Advances during any
         applicable LIBOR Interest Period; or (2) the LIBOR Fixed Rate will not
         adequately and fairly reflect the cost to the Lender of making,
         maintaining, or funding LIBOR Rate Advances for such LIBOR Interest
         Period, the Lender shall so notify the Borrower by telephone or telex
         (to be confirmed in writing) of such determination, whereupon, until
         the Lender notifies the Borrower that the circumstances which have
         given rise to such notice no longer exist, (A) the obligation of the
         Lender to provide the LIBOR Fixed Rate with respect to such LIBOR Rate
         Advances shall be suspended, and (B) such LIBOR Rate Advances shall be
         made, continued as, or





                                       15
<PAGE>   19
         converted to Base Rate Advances.

                 (b)      Increased Costs.  If due either to:  (1) the
         introduction of, or any change (including, without limitation, any
         change by way of any imposition or increase of reserve requirements)
         in the interpretation of, any law or regulation, including, without
         limitation, Regulation D or (2) the compliance by the Lender with any
         guideline or request from any central bank or other governmental
         authority (whether or not having the force of law), there shall be any
         increase in the cost to the Lender of agreeing to make, fund, or
         maintain the LIBOR Rate Advances (such costs being herein collectively
         called "Increased Costs"), the Borrower shall, from time to time, upon
         demand by the Lender, pay to the Lender, such additional amounts as
         are sufficient to indemnify the Lender against such Increased Costs.
         Absent manifest error, a certificate as to the amount of such
         Increased Costs, submitted to the Borrower by the Lender shall, for
         all purposes, be final, conclusive, and binding on the Borrower.  It
         shall be assumed for purposes of computing Increased Costs, that the
         making and maintaining of LIBOR Rate Advances has been by the Lender's
         principal office in New York City, New York.

                 (c)      Indemnity.  Without prejudice to any other provisions
         of this Agreement or any of the other Loan Documents, the Borrower
         shall indemnify the Lender against any loss or expense which the
         Lender (or its branches, subsidiaries, affiliates, or partners) may
         sustain or incur as a consequence of any Event of Default by the
         Borrower in making any payment when due of any amount due hereunder or
         in making any scheduled borrowing hereunder with respect to any LIBOR
         Rate Advance, including, without





                                       16
<PAGE>   20
         limitation, any loss of profit, premium or penalty incurred by the
         Lender (or its branches, subsidiaries, affiliates, or partners) in
         respect of funds borrowed by the Lender (or its branches,
         subsidiaries, affiliates, or partners), for the purpose of maintaining
         such LIBOR Rate Advance, as determined by the Lender in the exercise
         of its sole, but reasonable, discretion.  Absent manifest error, a
         certificate as to any such loss or expense submitted by the Lender to
         the Borrower shall, for all purposes, be final, conclusive, and
         binding on the Borrower.

         SECTION 2.08.    Prepayments.  The Borrower shall have the right to
prepay any principal amount of any Advance, in whole or in part, subject to the
requirements of Sections 2.05(i) and 2.09, but otherwise without premium or
penalty; provided, however, that each such partial prepayment shall be in an
integral multiple of $100,000, except that a prepayment may be in an amount
equal to the entire outstanding principal balance of all Advances.

         SECTION 2.09.    Indemnity and Release.  The Borrower shall indemnify
the Lender against any loss or expense which the Lender may sustain or incur as
a consequence of any failure by the Borrower to fulfill on the date of any
Advance hereunder the applicable conditions set forth in Article III, any
default in payment or prepayment of the principal amount of any Advance or any
part thereof or interest accrued thereon, as and when due and payable (at the
due date thereof, by irrevocable notice of prepayment, or otherwise), or the
occurrence of any Event of Default.  By its execution hereof, the Borrower
hereby certifies to the Lender that as of the date hereof, (i) all
representations and warranties heretofore made by it under any credit
agreement, promissory note or other instrument or document related thereto
which are amended





                                       17
<PAGE>   21
by or which relate to this Agreement are true in all material respects, (ii)
the Borrower does not have or claim to have any offset, counterclaim, or
defense to any of its obligations under any of such prior instruments or
documents, and (iii) in consideration of and to induce the Lender's agreement
to the terms of this Agreement, the Borrower, for itself and its successors and
assigns, does hereby RELEASE, ACQUIT, and FOREVER DISCHARGE the Lender, its
partners, officers, employees, agents, attorneys, other representatives and all
other persons, (collectively, the "Indemnitees") who might be liable, from any
and all claims, demands, liabilities, and causes of action of whatsoever
nature, whether in contract or in tort, or arising under or by virtue of any
statute, rule, regulation, or other laws, for all losses and damages, including
but not limited to exemplary and punitive damages, that have accrued or may
ever accrue to the Borrower and its successors and assigns, and which arise out
of, result from, or are caused by any act or omission of any one or more of the
Indemnitees on or prior to the date hereof in connection with the Loan
Documents, or any matter or thing in connection therewith or related thereto.
The Lender shall use its best efforts to mitigate any loss and to reduce any
expense for which it is being indemnified pursuant to this Section.

         SECTION 2.10.    Payments and Computations.  (a) The Borrower shall
         make each payment hereunder and under the Note not later than 12:00
         noon (New York City time) on the day when due in lawful money of the
         United States of America to the Lender for the account of Borrower at
         the Lender's office at 59 Wall Street, New York, New York 10005, in
         same day funds.

                 (b)  The Borrower hereby authorizes the Lender, if and to the
         extent payment for





                                       18
<PAGE>   22
         interest, principal, or fees is not made when due hereunder or under
         the Note, to charge from time to time against any of the Borrower's
         accounts with the Lender any amount so due.

                 (c)  Except to the extent the result would cause an interest
         rate to exceed the Maximum Rate, all computations of interest and of
         commitment fees hereunder shall be made by the Lender on the basis of
         a year of 360 days for the actual number of days (including the first
         day but excluding the last day) occurring in the period for which such
         interest or commitment fee is payable.

         SECTION 2.11.    Evidence of Debt.  The indebtedness of the Borrower
resulting from all Advances made from time to time shall be evidenced by a
promissory note of the Borrower, in substantially the form of Exhibit A hereto
(the "Note"), delivered to the Lender pursuant to Article III.

                                  ARTICLE III
                             CONDITIONS OF LENDING

         SECTION 3.01.    Condition Precedent to Initial Advance.  The
obligation of the Lender to make its initial Advance is subject to the
fulfillment, in a manner satisfactory to the Lender, of each of the following
conditions precedent:

                 (a)      The making of the Commitment shall not contravene any
         law, rule, or regulation applicable to the Lender.

                 (b)      No material adverse change in the condition or
         operations, financial or otherwise, of the Borrower, as reasonably
         determined by the Lender, shall have occurred





                                       19
<PAGE>   23
         and be continuing since the date of the latest audited financial
         statements of the Borrower provided to the Lender, the representations
         and warranties contained in Section 4.01 shall be true and correct,
         and no event shall have occurred and be continuing, or would result
         from such Advance, which constitutes or could constitute an Event of
         Default, as set forth in a certificate from an Authorized Officer of
         the Borrower dated as of the Closing Date.

                 (c)      The Lender shall have received on or before the
         Closing Date the following, in form and substance satisfactory to the
         Lender:

                          (i)     the Note, duly executed by the Borrower;

                 contemplated by the Loan Documents to which the Borrower is a

                 Borrower of the Loan Documents;

                          (iii)   a certificate, dated as of the Closing Date,

                 duly formed, is validly existing and in good standing under
                 the laws of the State of Delaware and has been duly qualified

                          (viii)  payment of a closing fee of $25,000.

         SECTION 3.02.    Conditions Precedent to All Advances.  The obligation
of the Lender to make each Advance shall be subject to the further conditions
precedent that, on the date of such Advance (a) the Lender shall have received
a notice of such Advance as required by Section 2.02 hereof, (b) the following
statements shall be true, and by making or sending any such notice of an

                          (ii)    No event has occurred and is continuing, or

                                   ARTICLE IV

                 (a)      The Borrower is a corporation duly organized and

         is duly qualified to do business and in good standing in the States of
         Texas, Louisiana, Alabama, and every other jurisdiction in which the
         transaction of any material portion of its business (as now conducted
         and as currently contemplated) makes such qualification necessary.

                 (b)      The execution, delivery, and performance by the
         Borrower of each Loan Document is within the Borrower's powers, has

                 (d)      This Agreement is, and each Loan Document to which
         the Borrower will be a party when delivered hereunder, will be the
         legal, valid, and binding obligations of the Borrower, legally
         enforceable against the Borrower in accordance with their respective
         terms.

                 (e)      Except as set forth on Schedule I hereto, there is no
         action, suit, or proceeding pending or threatened against or otherwise
         affecting the Borrower before any court, arbitrator, or governmental
         department, commission, board, bureau, agency, or instrumentality,
         which may materially adversely affect the condition or operations,
         financial or otherwise, of the Borrower or the ability of the Borrower
         to perform its obligations under the Loan Documents.

                 (f)      The financial statements of the Borrower heretofore
         provided to the Lender by the Borrower fairly present the financial
         condition of the Borrower as at the respective dates thereof, and the
         results of operations of the Borrower for the fiscal periods ended on
         such respective dates, all in accordance with generally accepted
         accounting principles consistently applied, subject to changes
         resulting from normal year-end audit adjustments, and, since December
         31, 1996, there has been no material adverse change in such condition
         or operations.

                 (g)      The Borrower is not engaged in the business of
         extending credit for the purpose of purchasing, carrying, or trading
         in securities (within the meaning of





                                       23
<PAGE>   27
         Regulation T issued by the Board of Governors of the Federal Reserve
         System), and no proceeds of any Advance will be used to purchase,
         carry, or trade in any such securities or to extend credit to others
         for the purpose of purchasing, carrying, or trading in any such
         securities.

                 (h)      All federal, state, and local tax returns and other
         material reports required by applicable law to be filed by the
         Borrower have been filed, and except with respect to any taxes,
         assessments, or other governmental charges being contested in good
         faith by the Borrower, all taxes, assessments, and other governmental
         charges imposed upon the Borrower or any of its properties which have
         become due and payable on or prior to the date hereof have been paid.

                 (i)      Each Employee Plan, if any, of the Borrower has
         satisfied the minimum funding standards under the Internal Revenue
         Code and ERISA applicable thereto, and no Employee Plan, if any, has
         an accumulated funding deficiency thereunder. The Borrower has not
         incurred any liability under ERISA to the Pension Benefit Guaranty
         Corporation with respect to any Employee Plan, and no Reportable Event
         or other event has occurred which could constitute grounds for the
         termination of any Employee Plan by the Pension Benefit Guaranty
         Corporation or the appointment of a trustee to administer any Employee
         Plan. The Borrower has not participated in any Prohibited Transaction
         with respect to any Employee Plan or trust created thereunder, and the
         consummation of the transactions contemplated hereby will not involve
         any Prohibited Transaction. The Borrower is not in the process of
         terminating any Employee Plan, which could result in the creation of
         any





                                       24
<PAGE>   28
         material liability for the Borrower.

                 (j)      The Borrower has not violated its charter or by-laws
         or any law, governmental regulation, order, judgment, or any agreement
         or instrument binding on or affecting it or any of its properties in
         such a manner so as to result in a material adverse change to the
         condition or operations, financial or otherwise, of the Borrower.

                 (k)      Except as set forth on Schedule II hereto, and except
         as may be created by statute, all of the real property owned by the
         Borrower, including any and all real property leasehold interests, is
         free and clear of all liens, security interests, and other charges and
         encumbrances.

                 (l)      The Borrower has not made a material misstatement of
         or failed to disclose a material fact to the Lender at any time during
         the course of the negotiations related to this Agreement or in
         connection with the Advances.

                 (m)      No proceeds of any Advance will be used to acquire
         any security in any transaction which is subject to Sections 13 and 14
         of the Securities Exchange Act of 1934. All proceeds of the Advances
         will be used for general corporate and working capital purposes.

                 (l)      Any action or proceeding shall be initiated by or

         secret, right, permit, license, or any other form of intellectual

         Borrower in appropriate proceedings





                                       34
<PAGE>   38
         deemed by the Lender to be satisfactory; or

                 (m)      Any event which, in the good-faith judgment of the
         Lender, constitutes or could reasonably be expected to constitute or

due and payable, without presentment, demand, protest, or further notice of any
kind, all of which are hereby expressly waived by the Borrower, (iii) take such
other actions as may be permitted under the Loan Documents, and (iv) exercise
any and all other remedies available under applicable law.

                                 MISCELLANEOUS

         SECTION 7.01.    Amendments, Etc.  No amendment or waiver of any
provision of the Loan Documents, nor consent to any departure by the Borrower
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Lender, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given.

         SECTION 7.02.    Notices, Etc.  Except as otherwise specifically
provided herein, all





                                       35
<PAGE>   39
notices and other communications provided for hereunder shall be in writing
(including telegraphic communication) and mailed or telegraphed or delivered,
if to the Borrower, at its address at 600 East Las Colinas Boulevard, Suite
1520, Irving, Texas 75039, Attention: Mr. Paul G. Vitek; if to the Lender, at
its address at 59 Wall Street, New York, New York 10005, Attention: Credit
Department; or, as to each party, at such other address as shall be designated
by such party in a written notice to the other party. All such notices and
communications shall, when mailed or telegraphed, be effective when deposited
in the mails or delivered to the telegraph company, respectively, addressed as
aforesaid.

         SECTION 7.03.    No Waiver; Remedies. No failure on the part of the
Lender to exercise, and no delay in exercising, any right under any Loan
Document shall operate as a waiver thereof; nor shall any single or partial
exercise of any right under any Loan Document preclude any other or further
exercise thereof or the exercise of any other right. The remedies provided in
the Loan Documents are cumulative and not exclusive of any remedies that may be
available to the Lender at law, in equity, or otherwise. No notice to or demand
on the Borrower in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances.

         SECTION 7.04.    Costs, Expenses, and Taxes.  (a) The Borrower agrees
to pay on demand all costs and expenses reasonably incurred by the Lender in
connection with the preparation, execution, delivery, filing, recording, and
administration of the Loan Documents and the other documents to be delivered
under the Loan Documents, including, without limitation, all fees and
out-of-pocket expenses of counsel for the Lender with respect thereto and





                                       36
<PAGE>   40
with respect to advising the Lender as to its rights and responsibilities under
the Loan Documents, and all costs and expenses, if any, in connection with the
enforcement of the Loan Documents and the other documents to be delivered under
the Loan Documents. In addition, the Borrower shall pay any and all stamp and
other taxes, excluding taxes imposed on net income and all income and franchise
taxes of the United States and any political subdivisions thereof (all such
non-excluded taxes being herein referred to as "Taxes") and fees, if any,
payable or determined to be payable in connection with the execution and
delivery of the Loan Documents and the other documents to be delivered under
the Loan Documents, and agrees to save the Lender harmless from and against any
and all liabilities with respect to or resulting from any delay by the Borrower
in paying or omission to pay such Taxes and fees.

         SECTION 7.05.    Right of Set-off.  Upon the occurrence and during the
continuance of any Event of Default, the Lender is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other indebtedness at any time owing by the
Lender to or for the credit or the account of the Borrower against any and all
of the obligations of the Borrower now or hereafter existing under this
Agreement and the Note, irrespective or whether or not the Lender shall have
made any demand under this Agreement or the Note and although such obligations
may be unmatured. The Lender agrees to use its best efforts to notify the
Borrower promptly after any such set-off and application, provided that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of the Lender under this Section are in addition to
other rights and remedies (including, without





                                       37
<PAGE>   41
limitation, other rights of set-off) which the Lender may have.

         SECTION 7.06.    Binding Effect.  This Agreement shall be binding upon
and inure to the benefit of the Borrower and the Lender, and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the Lender. The Lender may, with the Borrower's consent, such
consent not to be unreasonably withheld or delayed, assign to one or more banks
or entities all or any part of, or may grant participations to one or more
banks or other entities in or to all or any part of, any Advance or Advances
and the Note, and to the extent of any such assignment or participation (unless
otherwise stated therein), the assignee or participant of such assignment or
participation shall have the same rights and benefits hereunder and under the
Note as it would have if it were the Lender hereunder.

         SECTION 7.07.    Governing Law.  The Loan Documents shall be governed
by and construed in accordance with the laws of the State of Texas, except to
the extent any law, rule, or regulation of the federal government of the United
States of America may be applicable, in which case such federal law, rule, or
regulation shall govern and control; provided that the provisions of Chapter 15
of the Texas Credit Code shall not be applicable to this Agreement.

         SECTION 7.08     Merger of Agreements.  THE LOAN DOCUMENTS REPRESENT
THE FINAL AGREEMENT BETWEEN THE PARTIES HERETO AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES HERETO.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

                             REVOLVING CREDIT NOTE


U.S. $10,000,000
                                                        Dated: February 12, 1998


         FOR VALUE RECEIVED, the undersigned, CARBO CERAMICS INC., a Delaware
corporation (the "Borrower"), HEREBY PROMISES TO PAY to the order of BROWN
BROTHERS HARRIMAN & CO., a New York limited partnership (the "Lender") the
principal amount of each Advance made by the Lender to the Borrower pursuant to
the Credit Agreement (as hereinafter defined). All terms not otherwise defined
herein shall have the meanings set forth for such terms in the Credit
Agreement.

         The Borrower promises to pay interest on the unpaid principal amount
of each Advance from the date of such Advance until such principal amount is
paid in full, at such interest rate, and payable at such times, as are
specified in the Credit Agreement. In no event, however, shall the rate of
interest charged hereunder exceed the Maximum Rate.

         All agreements between the Borrower and the Lender, whether now
existing or hereafter arising and whether written for oral, are hereby
expressly limited so that in no event, whether by reason of acceleration of the
maturity hereof or otherwise, shall the amount paid or agreed to be paid to the
holder hereof for the use, forbearance or detention of the money to be loaned
hereunder or otherwise exceed the Maximum Rate. In fulfillment of any provision
hereof or of any loan agreement or other document evidencing or securing the
loan evidenced by this Note, at the time performance of such provision shall be
due, shall involve transcending the limit of validity prescribed by law, then,
ipso facto, the obligation to be fulfilled shall be reduced to the limit of
such validity; and if the holder of this Note shall ever receive anything of
value deemed to be interest under applicable law which would exceed interest at
the Maximum Rate, an amount equal to any such excessive interest shall be
applied to the reduction of the principal amount owing hereunder and not to the
payment of interest, or if such excessive interest exceeds the unpaid balance
of principal hereof, such excess shall be refunded to the Borrower. All sums
paid or agreed to be paid to the holder hereof for the use, forbearance, or
detention of the indebtedness of the Borrower to the Lender shall, to the
extent permitted by applicable law, be amortized, prorated, allocated, and
spread throughout the full term of such indebtedness until payment in full so
that the rate of interest of account of such indebtedness is uniform throughout
the term thereof. The provisions of this paragraph shall control all agreements
between the Borrower and the Lender.

         Both principal and interest are payable for the account of Borrower in
lawful money of the United States of America to the Lender at its offices at 59
Wall Street, New York, New York 10005, in same day funds. Each Advance made by
the Lender to the Borrower and the maturity thereof, and all payments made on
account of principal hereof, shall be recorded by the Lender and, prior to any
transfer hereof, either endorsed on the grid attached hereto which is part of
this Promissory Note or maintained in comparable form within the Lender's
internal books and records (which may be electronic).





<PAGE>   46
         The Borrower hereby affirms and certifies to the Lender that the
obligation evidenced by this note was not and will not be incurred for the
purposes of purchasing, carrying, or trading in securities, as defined in
Regulation T of the Board of Governors of the Federal Reserve System.

         This Promissory Note is the Note referred to in, and is entitled to
the benefits of, the First Amended and Restated Credit Agreement dated as of
February 12, 1998 (the "Credit Agreement") between the Borrower and the Lender.
The Credit Agreement, among other things, (i) provides for the making of
advances (the "Advances") by the Lender to the Borrower from time to time in an
aggregate amount not to exceed at any time outstanding the U.S. dollar amount
first above mentioned, the indebtedness of the Borrower resulting from each
such Advance being evidenced by this Promissory Note, and (ii) contains
provisions for acceleration of the maturity hereof upon the happening of
certain stated events and also for prepayments on account of principal hereof
prior to the maturity hereof upon the terms and conditions therein specified.

This Promissory Note shall be governed by and construed in accordance with the
laws of the State of Texas, except to the extent any law, rule, or regulation
of the federal government of the United States of America may be applicable, in
which case such federal law, rule, or regulation shall govern and control;
provided that the provisions of Chapter 15 of the Texas Credit Code shall not
be applicable to this Promissory Note.

         B.      Removing overburden from the Subject Properties in a manner so
                 as to allow Purchaser unimpeded access to a minimum of 40,000
                 tons of Product at any given time.

         C.      Maintaining roads to, from and across the Property in a manner

         D.      Reclaiming the Property in accordance with the permit(s)
                 Seller has obtained.

         E.      Providing to Purchaser a site of location, size and character
                 upon which to stockpile approximately 5,000 tons of the
                 Product and Seller shall mine such stockpile of 5,000 tons of
                 the Product at a cost to Purchaser of $1.35 per ton to be paid
                 upon completion of the stockpile.  Seller shall maintain such
                 stockpile at all times during this Agreement.

         F.      Seller shall mine sufficient quantities of the Product to fill
                 orders made by Purchaser on an "as needed" basis.

         G.      Seller shall deliver to the Purchaser's manufacturing plant
                 (the "Plant") in Wilkinson County, Georgia the quantities of
                 the Product ordered by Purchaser.

3.       QUANTITY

         A.      During the term of this Agreement, Seller shall make available
                 for sale to Purchaser and Purchaser shall have the right to
                 purchase from Seller up to 2,500,000 tons of the Product.  For
                 the purposes of this agreement, a "ton" shall be defined as a
                 weight of 2000 pounds of wet, crude Product.  "Wet" shall be
                 defined as any moisture content up to and including the
                 maximum amount specified in Exhibit A hereto.

         B.      In each year during the term of this Agreement, Purchaser
                 shall be obligated to purchase from Seller, as a minimum,
                 eighty percent (80%) of its actual annual requirements of the
                 Product during such year for its operations in Wilkinson
                 County, Georgia.  In the event Seller fails to deliver Product
                 in a timely manner which has been ordered by Purchaser and
                 Purchaser purchases such Product from another source,
                 Purchaser shall deduct the amount of such purchase from the
                 minimum purchase requirements set out in the preceding
                 sentence.

4.       PRICE

         A.      The price for the Product purchased from Seller shall be $6.00
                 per ton (the "Base Price Per Ton") delivered to Purchaser's
                 plant in Wilkinson County, Georgia.

         B.      The Base Price Per Ton, as adjusted from time to time, shall
                 be adjusted on May 1 of each year, beginning May 1, 1998,
                 using the percentage change between the previous two calendar
                 years' average monthly Producer Price Index ("PPI") for Kaolin
                 and Ball Clay (Product Code 1455) as published by the U.S.
                 Department of Labor, Bureau of Labor Statistics.  (For an
                 example of the calculation, see Appendix B.)


                                      2
<PAGE>   3

         C.      Beginning May 1, 1998, in addition to the Base Price Per Ton,
                 for each ton of Product mined and delivered to Purchaser,
                 Purchaser shall pay to Seller or Seller shall credit to
                 Purchaser a fuel cost adjustment (the "Fuel Cost Adjustment").
                 The Fuel Cost Adjustment shall be $1.20 multiplied by the sum
                 of one plus the percentage change between 1997 and the year
                 immediately preceding the calculation in the average monthly
                 Producer Price Index ("PPI") for No. 2 Diesel Fuel (product
                 code 2911-413) as published by the U.S. Department of Labor,
                 Bureau of Labor Statistics, less $1.20.  (For an example of
                 the calculation, see Appendix B.)

         D.      In addition to the Price Per Ton, Purchaser shall pay to
                 Seller any royalty costs in excess of $1.40 per ton of Product
                 mined and delivered to Purchaser, which are  payable by Seller
                 pursuant to the terms of written agreements with the
                 landowners of the Subject Properties in effect on the date
                 hereof.

5.       DELIVERY

         A.      Purchaser shall advise Seller within 180 days prior to the
                 start-up of its Wilkinson County, Georgia, plant of the
                 tonnage of its projected 1998 and 1999 purchases, and shall
                 thereafter advise Seller on or before October 1 of each year,
                 beginning October 1, 1999, of the tonnage of the Product it
                 projects to purchase during the next calendar year.  Such
                 projections should be estimates only and Purchaser shall not
                 be committed to purchase such amounts.  Purchaser shall use
                 reasonable efforts to advise Seller promptly in the event of
                 any change in its annual purchase projections for any year.

         B.      Purchaser and Seller shall communicate regularly, and Seller
                 shall ensure the availability of Product for sale hereunder on
                 an "as needed" basis.  Purchaser shall use its best efforts
                 (to the extent feasible) to space evenly its actual purchases
                 of the Product, and Seller shall be obligated to fill such
                 orders.

         C.      Risk of loss and title shall pass to Purchaser upon delivery
                 to Purchaser's plant in Wilkinson County, Georgia.

         in Wilkinson County, Georgia.  Invoices shall include a copy of the
         weight- ticket covering the Product being invoiced.

                 breakdowns or damage to plants, equipment or facilities,
                 interruptions to transport, embargoes, acts of military
                 authorities, acts of local or federal governmental agencies or
                 regulatory bodies, court actions, arrests and constraints and,
                 without limitation by enumeration, any other cause or causes
                 not reasonably within the control and without the fault or
                 negligence of the party affected which wholly or partly
                 prevents the mining, processing, loading or transportation of
                 Product by Seller or the receiving, transporting, accepting or
                 using of the Product by Purchaser.

         B.      If because of Force Majeure, either party hereto is unable to
                 carry out its obligations under this Agreement and if such
                 party shall promptly give to the other written notice of such
                 Force Majeure, including a complete description thereof, then
                 the obligation of the party giving such notice shall be
                 suspended to the extent made necessary by Force Majeure and
                 during its continuance; provided, however, that the party
                 giving such notice shall use its best efforts to eliminate
                 such Force Majeure insofar as possible with a minimum of
                 delay.  No event of Force Majeure shall relieve Purchaser of
                 its obligation to make payments due for Product delivered by
                 Seller under this Agreement.


13.      EVENTS OF DEFAULT

         In the absence of the existence of force majeure as defined in
         paragraph 12, if any of the following events ("Events of Default")
         shall occur and be continuing:

         A.      Any amount due hereunder, unless being disputed in good faith,
                 shall remain unpaid for thirty (30) days after becoming due,
                 and the party adversely affected shall have delivered a notice
                 to the party owing such amount stating the amount due and
                 unpaid, and the party owing (and not disputing same in good
                 faith) shall not have paid such amount within thirty (30) days
                 after the delivery of such notice; or

         B.      Seller shall fail or refuse to provide to Purchaser the amount

         C.      Any deliveries of kaolin materials to Purchaser hereunder
                 shall fail to meet the quality specifications provided in

         D.      Any other covenant, obligation or agreement by either party
                 hereunder shall not be performed or observed within twenty

                 shall have been delivered to the nonperforming party by the
                 other party; or

         E.      Either party shall:

                 (1)      Fail to pay any judgment in an amount which would
                          materially affect the net worth of such party within
                          sixty (60) days after issuance of a writ of execution
                          upon such final judgment;

                 (2)      Apply for or consent to the appointment of a
                          receiver, trustee or liquidator of such party or of

                 (3)      Make a general assignment for the benefit of its
                          creditors;

                 (4)      Be adjudicated bankrupt or insolvent, or file a

                 (5)      File a petition or an answer seeking reorganization
                          under any insolvency law; or

                 (6)      File an answer admitting the material allegations of,
                          or consent to, or default in answering, a petition
                          filed against it in any bankruptcy, reorganization or
                          insolvency proceeding; or

         F.      An order, judgment or decree shall be entered by any court of
                 competent jurisdiction approving a petition seeking
                 reorganization of such party or appointing a receiver, trustee
                 or liquidator of a party or of all or a substantial part of
                 its assets and such order, judgment or decree shall continue
                 unstayed and in effect for a period of thirty (30) consecutive
                 days;

         G.      Any of the representations or warranties made by a party
                 herein shall be or become untrue in any material respect; or

         H.      Seller shall be in default under any lease of any portion of

                                     10

then the party adversely affected by such Event of Default shall, in addition
to other remedies available to such party at law or in equity, have any one (1)
or more of the following remedies:

                 (1)      The party adversely affected by such Event of Default
                          may by written notice delivered to the other party
                          decline to perform under this Agreement until such
                          Event of Default shall have been cured or shall no
                          longer exist, without relieving the defaulting party
                          of any of its obligations hereunder;

                 (2)      The party adversely affected by such Event of Default
                          may, effective upon twenty (20) days' written notice
                          to such effect delivered to the other party,
                          terminate this Agreement without relieving the other
                          party from any liability which shall have accrued or
                          attached on or prior to the effective date of such
                          termination; and/or

                 (3)      If Seller is in default for failure to deliver
                          Product at the time requested or for delivering
                          kaolin materials failing to meet quality
                          specifications, Purchaser may recover all damages
                          caused by such failure or Purchaser may purchase such
                          quantities of Product from another source and Seller
                          shall reimburse Purchaser within twenty (20) days
                          from invoice for any additional cost incurred by
                          Purchaser above the Price Per Ton provided herein and
                          for any costs incidental to obtaining such other
                          supply.  Termination of this Contract for any of the
                          causes herein contained shall be without prejudice to
                          any other right or remedy provided by this Contract
                          or at law or in equity.  Failure of either Purchaser
                          or Seller immediately to exercise its rights in any
                          Event of Default will not constitute waiver of the
                          injured party's rights.  Both parties agree to use
                          their best efforts to minimize the amount of damages
                          that may be incurred as the result of an Event of
                          Default.

         Purchaser to Seller and all payments to be made by Purchaser to Seller
         hereunder shall be delivered personally to Seller or sent to Seller at
