                                 PART I
ITEM 1.           BUSINESS.


GENERAL DESCRIPTION OF BUSINESS

         Georgia Gulf Corporation is a major manufacturer and worldwide 
marketer of two highly integrated product lines, chlorovinyls and aromatic 
chemicals; and also a third product line, methanol, a natural gas chemical. 
Georgia Gulf's chlorovinyl products include chlorine, caustic soda, sodium 
chlorate, vinyl chloride monomer ("VCM") and polyvinyl chloride ("PVC") 
resins and compounds. Georgia Gulf's primary aromatic chemical products 
include cumene, phenol and acetone. For selected financial information 
concerning these product lines, see Note 18 to Georgia Gulf's consolidated 
financial statements incorporated by reference in Item 14.

         Georgia Gulf has operated as an independent corporation since its 
acquisition on December 31, 1984, of a major portion of the business and 
assets of the chemical division of Georgia-Pacific Corporation. Georgia 
Gulf's operations include:

         --        production units at six locations;
         --        several marketing organizations to handle sales;
         --        a technical service laboratory; and
         --        a purchasing organization to buy all major raw materials.

At Georgia Gulf's six manufacturing locations, there are thirteen plants 
including six located in Plaquemine, Louisiana. Georgia Gulf also owns an air 
separation plant located in Plaquemine, Louisiana, which supplies all of the 
oxygen and nitrogen requirements for the complex. Georgia Gulf leases a 
cogeneration facility that supplies essentially all of the electricity and 
steam requirements for the Plaquemine, Louisiana, complex. In addition, 
Georgia Gulf leases storage terminals and warehouses from which a portion of 
its products is distributed to customers.

         Georgia Gulf's products are generally intermediate chemicals that 
are sold for further processing into a wide variety of end-use applications. 
Some of the more significant end-use markets include:

         --        plastic pipe and pipe fittings, window lineals and siding,
                   wire and cable insulation, packaging material and containers
                   made from vinyl resins and compounds;
         --        adhesives for wood products and high quality plastics made 
                   from phenol;
         --        acrylic sheeting for automotive and architectural products
                   made from acetone; and
         --        formaldehyde and methyl tertiary-butyl ether ("MTBE"), a 
                   gasoline additive, produced from methanol.

         The following percentages of sales were made in 1998 to manufacturers
in the following industries:


                INDUSTRY                        PERCENTAGE OF SALES
- -----------------------------------------  -----------------------------
Housing and construction                                31%
Plastics and fibers                                     22%
Solvents and chemicals                                  18%
Consumer products                                       16%
Pulp and paper                                          4%
Miscellaneous                                           9%

                                     1

         In the commodity chemical industry, the cost of raw materials, as 
well as the overall industry capacity and demand for particular product 
lines, significantly affect pricing of products. These factors also impact 
Georgia Gulf's earnings and cash flow. Georgia Gulf has invested $613 million 
in the past five years to maintain, expand and improve the efficiency of its 
operating facilities. The major planned capital expenditures for 1999 will be 
directed toward certain environmental projects and increased efficiency of 
existing operations. Management believes that with its low-cost position and 
integrated product lines, Georgia Gulf is well-positioned to compete in its 
various product lines.

         Georgia Gulf's long-term strategy is to continue to make investments 
that will improve or maintain its low-cost position, as well as selective and 
prudent capacity additions and expansions in its core product areas. In 
addition, Georgia Gulf will consider acquisitions, joint ventures or similar 
transactions that management believes will promote profitable growth in 
present and closely related product lines.

CHLOROVINYL PRODUCTS

         CHLORINE/CAUSTIC SODA/SODIUM CHLORATE. Georgia Gulf's facility at 
Plaquemine, Louisiana, has the annual capacity to produce the following:

       --        450 thousand tons of chlorine;
       --        500 thousand tons of caustic soda, chlorine's co-product; and
       --        27 thousand tons of sodium chlorate.

The major raw materials for these products are salt and electric power. 
Georgia Gulf has a long-term lease on a salt dome near the Plaquemine 
facility. The salt dome has sufficient salt reserves to last over thirty 
years at current rates of production. Electric power is the most significant 
cost component in the production of these products. Georgia Gulf operates a 
250-megawatt cogeneration facility located at the Plaquemine, Louisiana, 
complex. This facility supplies, under a long-term lease agreement, 
essentially all of the electricity and steam requirements for that site. The 
primary cost component of producing electricity in the cogeneration facility 
is natural gas.

         Chlorine is used in the production of various chemicals, including 
those used to make vinyl resins. In 1998, approximately 92 percent of Georgia 
Gulf's chlorine production was consumed internally in the production of VCM, 
which Georgia Gulf uses to produce vinyl resins. Georgia Gulf sells the 
remaining chlorine principally to the pulp and paper and chemical industries.

         The major uses of caustic soda are in the production of pulp and 
paper and aluminum. Caustic soda also has applications in the production of 
other chemicals and in chemical processes where caustic soda is used to 
control pH levels, aiding in waste neutralization. Another use is in the 
textile industry where it makes fabrics more absorbent and improves the 
strength of dyes. Caustic soda is also used, to a lesser extent, in food 
processing, electroplating and detergents.

         The predominant use for sodium chlorate is in the bleaching process 
for pulp and paper.

         VCM. Georgia Gulf produces VCM at its Plaquemine, Louisiana, 
complex. The major raw materials used to produce VCM are purchased ethylene 
and internally-produced chlorine. The VCM plant's annual capacity is 
approximately 1.6 billion pounds with the capability of also producing an 
additional 400 million pounds of ethylene dichloride ("EDC"), the precursor 
to VCM. Approximately 79 percent of the VCM production in 1998 was used by 
Georgia Gulf's PVC resins operations with the remainder being sold to other 
PVC resins producers, particularly in the export market.

                                    2

<PAGE>


          PVC RESINS. Georgia Gulf operates a world-scale PVC resins plant in 
Plaquemine, Louisiana. The plant is located adjacent to its major raw 
material supplier, the VCM facility. This minimizes transportation and 
handling costs. The annual production capacity is approximately 1.12 billion 
pounds.

         PVC resins are among the most widely used plastics in the world 
today. After being formulated and compounded to desired properties, PVC 
resins are heated and shaped into finished products by various extrusion and 
molding processes. Georgia Gulf uses approximately one-fourth of its PVC 
resin internally in the production of vinyl compounds. The remainder of the 
production is sold to other vinyl compound manufacturers or to downstream 
manufacturers who compound PVC resins internally.

         VINYL COMPOUNDS. Vinyl compounds blend PVC resins with various 
additives such as plasticizers, impact modifiers, stabilizers and pigments to 
achieve desired properties. Georgia Gulf's vinyl compounding plants have an 
aggregate annual capacity of approximately 570 million pounds and are located 
in Tiptonville, Tennessee, and Aberdeen, Gallman and Madison, Mississippi.

         Vinyl compounds are formulated to provide specific end-use 
properties that allow the material to be processed directly into a finished 
product. All sales of vinyl compounds are to outside customers. This product 
line can be segregated into five major product areas according to the 
following process applications:

         INJECTION MOLDING -- Georgia Gulf supplies various vinyl compounds,
         which are used in the business machine market for computer housings 
         and keyboards. It also supplies vinyl compounds to produce electrical
         outlet boxes. These proprietary compounds have extensive approval
         procedures by customers or regulatory bodies. Georgia Gulf also
         manufactures vinyl compounds for use in pipe fittings.

         EXTRUSION -- Georgia Gulf supplies extrusion markets which have
         applications in window and furniture profiles and extruded sheets for
         household fixtures and decorative overlays.

         FLEXIBLE -- Georgia Gulf supplies flexible compounds for wire and 
         cable for construction, automobiles and appliances, and other consumer
         and industrial purposes.

         CHLORINATED POLYVINYL CHLORIDE ("CPVC") -- Georgia Gulf supplies
         Protherm(R) CPVC compounds to the extrusion and injection molding
         markets, mainly for pipe and pipe fittings.

         BLOW MOLDING -- Georgia Gulf is a supplier of blow molding compounds,
         which are primarily used for both food-grade and general purpose
         bottles. Supplied in both clear and opaque colors, these bottles are
         used to package cosmetics, shampoos, charcoal lighter fluid, water and
         edible oils.

AROMATIC CHEMICAL PRODUCTS

         CUMENE. Cumene is produced at the Pasadena, Texas, facility located 
on the Houston ship channel. Georgia Gulf's cumene plant is one of the 
world's largest and has an annual capacity of approximately 1.5 billion 
pounds. Cumene is produced from benzene and propylene purchased from various 
suppliers in the surrounding area. Approximately 68 percent of the 1998 
cumene output was consumed internally to produce phenol and its co-product, 
acetone. The balance was sold into the merchant market to other phenol and 
acetone manufacturers.

                                    3

<PAGE>



         PHENOL/ACETONE. Phenol and acetone are produced at the Plaquemine, 
Louisiana and Pasadena, Texas facilities. The Plaquemine facility has 
approximately 500 million pounds of phenol capacity and 308 million pounds of 
acetone capacity per year. The Pasadena facility has annual capacity of 160 
million pounds of phenol and 100 million pounds of acetone.

         Phenol is a major ingredient in phenolic resins, which are used 
extensively as adhesives for wood products such as plywood and granulated 
wood panels. Phenol is also used in insulation, electrical parts, nylon 
carpeting, oil additives and pharmaceuticals. Phenol is also a precursor to 
high performance plastics used in compact discs, automobiles, household 
appliances, electronics and protective coating applications.

         The primary uses for acetone are as a key ingredient to methyl 
methacrylate, which is used to produce acrylic sheeting, and as an ingredient 
for surface coating resins for automotive and architectural markets. Acetone 
is also an intermediate for the production of engineering plastics and 
several major industrial solvents. Other uses range from wash solvents for 
automotive and industrial applications to pharmaceuticals and cosmetics.

         As a result of the phenol/acetone manufacturing process, Georgia 
Gulf also produces and markets small amounts of a by-product, 
alpha-methylstyrene ("AMS"). AMS is primarily used as a polymer modifier and 
as a chemical intermediate.

METHANOL
          Methanol is produced at Georgia Gulf's facility at Plaquemine, 
Louisiana, which has an annual capacity of approximately 160 million gallons. 
Natural gas represents the majority of the cost of the production of 
methanol. The Plaquemine facility is in the center of Louisiana's oil and gas 
producing region and has three separate pipeline systems that can deliver gas 
to the plant. Natural gas is purchased by Georgia Gulf under contracts at 
market prices from both producers and gas pipeline suppliers.

         A key use for methanol is in the production of MTBE, an additive 
that promotes cleaner burning gasoline by adding oxygen. Methanol is also 
used as a raw material in the manufacture of formaldehyde, an ingredient in 
adhesives for building materials such as granulated wood panels and plywood. 
Other applications for methanol include windshield washer fluid, solvents, 
acrylic sheeting, coatings, fibers and household adhesives.

         In 1998, substantial increases in global supply created a 
significant imbalance between supply and demand, which had a serious impact 
on profitability for the methanol industry. In the United States, producers 
face increased competition from low-cost imports. As a result, Georgia Gulf 
has temporarily shut down operations of its methanol plant and is supplying 
customers by purchasing methanol from offshore suppliers. Georgia Gulf is 
presently examining a range of options to enhance the value of the methanol 
business and take advantage of Georgia Gulf's customer base and extensive 
distribution system.

GREAT RIVER OIL & GAS CORPORATION
          In July 1997, Georgia Gulf sold oil and gas properties representing 
most of the assets of Great River Oil & Gas Corporation, a subsidiary of 
Georgia Gulf. Net proceeds from this sale were $16,477,000, on which Georgia 
Gulf recorded a pretax gain of $8,600,000 ($5,300,000, net of income taxes). 
Historically, the operating results for this subsidiary had not been material 
to the operating results or financial condition of Georgia Gulf.

NORTH AMERICAN PLASTICS, INC.
          On May 11, 1998, Georgia Gulf acquired all the issued and 
outstanding common stock of North American Plastics, Inc., a privately held 
manufacturer of flexible vinyl compounds with a production capacity of 
190,000,000 pounds. North American Plastics has two manufacturing locations 
in Mississippi and generated approximately $90,000,000 in revenue in 1997. 
Its vinyl compounds are used in wire and cable for construction, automobiles 
and appliances, as well as various other consumer and industrial products.

         The stock of North American Plastics was acquired in exchange for 
net cash consideration of $99,902,000 plus the assumption of $500,000 in 
debt. The cash portion of the acquisition was financed with proceeds from 
Georgia Gulf's existing revolving credit facility. The transaction was 
accounted for as a purchase, and the consideration exchanged exceeded the 
fair market value of the net tangible assets of North American Plastics by 
$86,725,000. This excess was allocated to goodwill and is being amortized on 
a straight-line basis over a period of 35 years. The results of operations of 
the acquired business have been included in Georgia Gulf's consolidated 
financial statements from the date of acquisition. Pro forma results of 
operations have not been presented because the effect of this acquisition was 
not significant.

SIGNIFICANT CUSTOMER

         Georgia Gulf has supply contracts, subject to some limitations, for 
significant percentages of Georgia-Pacific Corporation's requirements for 
caustic soda, methanol and phenol. These supply contracts provide for prices 
approximating the market. These supply contracts have various expiration 
dates (depending on the product) from 1999 through 2003 and may be extended 
year-to-year upon expiration. Sales under these contracts were about 11% of 
total sales in 1998, 12% in 1997 and 15% in 1996.

MARKETING AND SALES

         Georgia Gulf's marketing program is aimed at expanding and 
diversifying its customer base. Other than Georgia-Pacific Corporation, no 
single customer represents more than 10% of Georgia Gulf's net sales. Export 
sales accounted for about 17% of total sales in 1998, 15% in 1997 and 12% in 
1996. The principal international markets served by Georgia Gulf are Canada, 
Mexico, Latin America, Europe and Asia.

         Georgia Gulf markets its products primarily to industrial customers. 
The sales force is organized by product line. The sales organization, located 
throughout the United States, is supported by a technical service staff.

RAW MATERIALS

         The most important raw materials purchased by Georgia Gulf are 
natural gas, ethylene, benzene, propylene and salt. Raw materials used for 
production of Georgia Gulf's products are usually purchased from various 
suppliers at market prices under supply contracts, some of which are 
long-term take or pay agreements. Since raw materials account for a 
significant portion of Georgia Gulf's total production cost, its ability to 
pass on increases in these costs to its customers has a significant impact on 
operating results. The ability to pass on increases is, to a large extent, 
related to industry

                                     5

capacity and market demand. Georgia Gulf's leased cogeneration facility 
supplies essentially all of the electricity and steam requirements for its 
Plaquemine production facilities. Management believes Georgia Gulf has a 
reliable supply base of raw materials under normal market conditions. Georgia 
Gulf cannot predict the impact of any future raw material shortages.

COMPETITION

         Georgia Gulf experiences competition from numerous manufacturers in 
all of its product lines. Some of Georgia Gulf's competitors have 
substantially greater financial resources and are more highly diversified 
than Georgia Gulf. Georgia Gulf competes on a variety of factors such as 
price, product quality, delivery and technical service.

         Management believes that Georgia Gulf is well-positioned to compete 
as a result of integrated product lines, the operational efficiency of its 
plants and the location of its facilities near major water and/or rail 
transportation terminals.

EMPLOYEES

         As of December 31, 1998, Georgia Gulf had 1,050 full-time employees. 
Georgia Gulf has one collective bargaining agreement, which covered 
fifty-three employees at the Tiptonville, Tennessee, facility as of December 
31, 1998.

ENVIRONMENTAL REGULATION

         Georgia Gulf's operations are subject to increasingly stringent 
federal, state and local laws and regulations relating to environmental 
quality. These regulations are enforced principally by the United States 
Environmental Protection Agency and comparable state agencies. These 
regulations govern the management of solid hazardous waste, emissions into 
the air and discharges into surface and underground waters, and the 
manufacture of chemical substances.

         Management believes that Georgia Gulf is in material compliance with 
all current environmental laws and regulations. Georgia Gulf estimates that 
any expenses incurred in maintaining compliance with these requirements will 
not materially affect earnings or cause it to exceed its level of anticipated 
capital expenditures. However, there can be no assurance that regulatory 
requirements will not change, and Georgia Gulf cannot predict the aggregate 
cost of compliance resulting from any such changes.

YEAR 2000 COMPUTER SYSTEMS COMPLIANCE

         Georgia Gulf has recognized the need to ensure its operations will 
not be adversely impacted by the Year 2000 date conversion situation common 
in many data processing systems. All of Georgia Gulf's financial reporting 
systems have been acquired or developed within the past seven years. The 
installation of these systems is complete and testing indicates these systems 
are Year 2000 compliant. Process control software controls the operation of 
many of Georgia Gulf's plants. This process control software was updated to 
Year 2000 compliant versions during 1998.

         Management believes its remaining Year 2000 exposure exists 
primarily with personal computers and external partners. The remaining 
exposure related to the personal computers will be addressed during the first 
half of 1999. Third parties critical to Georgia Gulf, both suppliers and 
customers, were contacted during the first quarter of 1999 in order to 
develop appropriate contingency plans, if necessary. The additional Year 2000 
conversion costs are not expected to be material.

FORWARD-LOOKING STATEMENTS

         This Form 10-K and other communications to stockholders, as well as 
oral statements made by representatives of Georgia Gulf, may contain 
"forward-looking statements" within the meaning of the Private Securities 
Litigation Reform Act of 1995. These statements relate to, among other 
things, Georgia Gulf's outlook for future periods, supply and demand, pricing 
trends and market forces within the chemical industry, cost reduction 
strategies and their results, planned capital expenditures, long-term 
objectives of management and other statements of expectations concerning 
matters that are not historical facts.

         Predictions of future results contain a measure of uncertainty. 
Actual results could differ materially due to various factors. Factors that 
could change forward-looking statements are, among others:

         --      changes in the general economy;
         --      changes in demand for Georgia Gulf's products or increases in
                 overall industry capacity that could affect production volumes
                 and/or pricing;
         --      changes and/or cyclicality in the industries to which Georgia 
                 Gulf's products are sold;
         --      availability and pricing of raw  materials;
         --      technological changes affecting production;
         --      difficulty in plant operations and product transportation;
         --      governmental and environmental regulations; and
         --      other unforeseen circumstances.

         A number of these factors are discussed in this Form 10-K and in 
Georgia Gulf's other periodic filings with the Securities and Exchange 
Commission.

ITEM 2.  PROPERTIES.

         Georgia Gulf's asset base was established from 1971 to the present 
with the construction of the Plaquemine, Louisiana, complex; the construction 
of the Pasadena, Texas, cumene plant; and the purchase of the PVC compound 
plants. Georgia Gulf purchased the Bound Brook, New Jersey, phenol/acetone 
facility which was subsequently relocated to Pasadena, Texas, and modernized 
in 1990. In 1996, Georgia Gulf sold its vinyl emulsion business including the 
property and buildings at the Delaware City location. In 1997, Georgia Gulf 
completed construction of cogeneration and air separation plants in 
Plaquemine, Louisiana, in order to supply substantially all of its 
requirements for electricity, oxygen and nitrogen at that location. The 
cogeneration plant is leased under an operating lease agreement. In 1998, 
Georgia Gulf purchased North American Plastics, Inc., a manufacturer of 
flexible vinyl compounds with production facilities in Aberdeen and Madison, 
Mississippi. With the exception of the cogeneration plant, Georgia Gulf owns 
each of these facilities.

         Georgia Gulf continues to explore ways to expand both its plant 
capacities and product lines. Georgia Gulf believes current and additional 
planned capacity will adequately meet anticipated demand requirements. 
Average capacity utilization of Georgia Gulf's production facilities in 1998 
was 91%.

</TABLE>

         Georgia Gulf's manufacturing facilities are located near major water 
and/or rail transportation terminals, facilitating efficient delivery of raw 
materials and prompt shipment of finished products. In addition, Georgia Gulf 
has a fleet of 2,446 railcars of which 713 are owned and the remainder leased 
pursuant to operating leases with varying terms through the year 2010. The 
total lease expense for these railcars and other transportation equipment was 
approximately $10,108,000 for 1998.

         Georgia Gulf makes lease payments under an operating lease agreement 
for the 250-megawatt cogeneration facility at the Plaquemine, Louisiana, 
complex. The lease expense under the operating lease agreement for 1998 was 
approximately $11,629,000.

         Georgia Gulf leases office space for its principal executive offices 
in Atlanta, Georgia, and for information services in Baton Rouge, Louisiana. 
Space is leased for sales and marketing offices in Houston, Texas; 
Schaumburg, Illinois; and Lawrenceville, New Jersey. Space for numerous 
storage terminals is leased throughout the United States, and in the 
Netherlands, Canada, New Zealand, Mexico and South Korea.

ITEM 3.  LEGAL PROCEEDINGS.
          Georgia Gulf is a party to numerous individual and several 
class-action lawsuits filed against Georgia Gulf, among other parties, 
arising out of an incident that occurred in September 1996 in which workers 
were exposed to a chemical substance on Georgia Gulf's premises in 
Plaquemine, Louisiana. The substance was later identified to be a form of 
mustard agent, a chemical which is not manufactured as part of Georgia Gulf's 
ordinary operations, but instead occurred as a result of an unforeseen 
chemical reaction. Georgia Gulf presently believes there are approximately 
2,000 plaintiffs,

                                     8

<PAGE>

of which approximately 650 are workers claiming to have been onsite at the 
time of the incident. All of the actions claim one or more forms of 
compensable damages, including past and future wages, past and future 
physical and emotional pain and suffering, and medical monitoring. The 
lawsuits were originally filed in Louisiana State Court in Iberville Parish.

         Discovery has been occurring in these cases. Georgia Gulf continues 
to develop information relating to the extent of damages suffered, as well as 
evaluating the merit of such claims, defenses available and liability of 
other persons.

         In September 1998, the plaintiffs filed amended petitions that added 
the additional allegations that Georgia Gulf had engaged in intentional 
conduct against the plaintiffs. These additional allegations raised a 
coverage issue under Georgia Gulf's general liability insurance policies. In 
December 1998, as required by the terms of the insurance policies, the 
insurers demanded arbitration to determine whether coverage is required for 
the alleged intentional conduct in addition to the coverage applicable to the 
other allegations of the case. The date for the arbitration has not yet been 
established.

         As a result of the arbitration relating to the insurance issue, as 
permitted by federal statute, the insurers removed the cases to United States 
District Court in December 1998. The plaintiffs filed motions contesting the 
jurisdiction of the federal court and seeking to remand the cases back to 
state court, and a hearing on the issue was held in federal court on January 
15, 1999. By order entered March 2, 1999, the federal court denied the 
plaintiff's motion to remand the cases back to state court and retained 
federal jurisdiction.

         Settlements have been reached with approximately 260 of the original 
workers, including the majority of those claimants believed to be the most 
severely injured, and the settled cases have been or will be dismissed. 
Additionally, settlements have been reached or are being negotiated with 
other parties named as defendants whereby such parties have made, or are 
being requested to make, contributions to the recoveries made by the 
plaintiffs. Negotiations for the resolution of the remaining claims are 
continuing.

         Notwithstanding the foregoing, Georgia Gulf is asserting and 
pursuing defenses to the claims. Based on the present status of the 
proceedings, Georgia Gulf believes the liability ultimately imposed will not 
have a material effect on the financial position or on results of operations 
of Georgia Gulf.

         In addition, Georgia Gulf is subject to other claims and legal 
actions that may arise in the ordinary course of business. Management 
believes that the ultimate liability, if any, with respect to these other 
claims and legal actions, will not have a material effect on the financial 
position or on results of operations of Georgia Gulf.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

         No matters were submitted to a vote of security holders during the 
fourth quarter of 1998.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON
                        FINANCIAL STATEMENT SCHEDULE



To Georgia Gulf Corporation:



         We have audited, in accordance with generally accepted auditing 
standards, the financial statements included in Georgia Gulf Corporation's 
Annual Report to Stockholders incorporated by reference in this Form 10-K, 
and have issued our report thereon dated February 12, 1999. Our audit was 
made for the purpose of forming an opinion on those statements taken as a 
whole. The schedule listed in Item 14 of this Form 10-K is the responsibility 
of Georgia Gulf's management and is presented for purposes of complying with 
the Securities and Exchange Commission's rules and is not part of the basic 
financial statements. This schedule has been subjected to the auditing 
procedures applied in the audit of the basic financial statements and, in our 
opinion, fairly states in all material respects the financial data required 
to be set forth therein in relation to the basic financial statements taken 
as a whole.

(1) All years subsequent to 1989 include the effects of the recapitalization,
    which occurred in April 1990. (See Note 8 to the consolidated financial
    statements.)
 
(2) Earnings before interest, taxes, depreciation and amortization ("EBITDA") is
    commonly used by certain investors to measure a company's ability to service
    its indebtedness. EBITDA is not a measurement of financial performance under
    generally accepted accounting principles and should not be considered as an
    alternative to net income as a measure of performance or to cash flow as a
    measure of liquidity. For 1998, the loss on interest rate hedge agreement
    has been included as interest expense for the computation of EBITDA.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                            GEORGIA GULF CORPORATION
 
RESULTS OF OPERATIONS
 
    Georgia Gulf manufactures and markets two highly integrated chemical product
lines, chlorovinyls and aromatics; and also a third product line, methanol, a
natural gas chemical. The Company's chlorovinyl products include chlorine,
caustic soda, sodium chlorate, vinyl chloride monomer ("VCM"), and vinyl resins
and compounds; the Company's primary aromatic chemical products include cumene,
phenol and acetone.
 
    Georgia Gulf's business, and the chemical industry in general, is cyclical
in nature and is affected by world economic conditions. The level of domestic
chemical sales and product pricing tends to reflect fluctuations in downstream
markets that are affected by consumer spending for durable goods and
construction spending. Global capacity of certain chemicals also affects the
supply and demand for the products the Company manufactures and markets.
 
1998 COMPARED WITH 1997--For the year ended December 31, 1998, diluted earnings
per share were $1.77 on net income of $56.3 million and net sales of $875.0
million. This compares with diluted earnings per share of $2.39, net income of
$81.2 million and net sales of $965.7 million for 1997.
 
    Operating income for 1998 was $130.0 million, a decrease of 11 percent from
$146.8 million in 1997. Total sales volume increased slightly over the prior
year as increased sales volume in chlorovinyls more than offset declines in
aromatics and methanol. The average selling price of the Company's products
declined 10 percent for the period-to-period comparison. With the exception of
caustic soda, pricing declined for all products; however, lower raw material
costs helped mitigate a portion of these sales price decreases. Operating income
also included a reduction in maintenance expense of $5.1 million for the
deferment of certain plant turnarounds until 1999.
 
    In chlorovinyls, industry operating rates for chlorine/caustic soda plants
ran above 90 percent for most of 1998. Georgia Gulf markets all of its caustic
soda and consumes most of its chlorine, while approximately 72 percent of VCM
production is used internally in the manufacture of vinyl resins. Approximately
37 percent of the Company's vinyl resin is used internally to produce vinyl
compounds. Both VCM and vinyl resins have suffered from industry overcapacity,
resulting in excess supply and reduced operating rates in both 1998 and 1997.
Demand from Asia has also suffered as a result of the economic troubles in that
region. However, the market demand for vinyl compounds remained strong in 1998,
benefitting from the continued strength of the United States economy. In
addition, the acquisition in May 1998 of North American Plastics, Inc., a
manufacturer of flexible vinyl compounds, has contributed positively to earnings
of the Company's vinyl compounds business.
 
    The Company's chlorovinyls business had a higher profit contribution of
$80.2 million in 1998 as compared with $69.8 million in 1997 as sales volume
increased 10 percent, offsetting a 5 percent decrease in sales prices. Sales
volumes were up for most chlorovinyl products in 1998, especially vinyl
compounds which included the flexible vinyl compound sales of newly acquired
North American Plastics. Sales prices for all chlorovinyl products were lower,
with the exception of caustic soda. However, caustic soda did begin to weaken in
the second half of 1998, largely due to a combination of high caustic/chlorine
operating rates and lower demand from pulp and paper producers. Pricing pressure
is expected to continue into 1999 for caustic/chlorine as two major expansions
are scheduled for completion in 1999. Industry operating rates during 1998 for
VCM plants were in the high 80 percent range for most of the year as producers
adjusted production levels to meet reduced export demand. Prices were negatively
impacted from this oversupply situation as well. Vinyl resins have endured an
eighteen-month decline in sales prices also due to industry overcapacity, but
pricing did begin to improve slightly toward the end of 1998. There are no
significant vinyl resin capacity additions scheduled for 1999, which should lead
to a more balanced market and higher pricing levels.
 
                                       4
<PAGE>
    Aromatic industry operating rates were high for 1998 as a result of strong
demand attributable to the continued strength of downstream markets for phenol,
particularly bisphenol-A and phenolic resins. The Company's aromatics business
generated $73.4 million in operating income for 1998 as compared to $71.1
million for 1997. Sales volume for aromatic chemicals in 1998 decreased 4
percent from 1997 levels, as a drop in cumene volume more than offset increases
in both phenol and acetone volumes. The average sales price for the entire
aromatic chemical chain declined approximately 14 percent in 1998, as compared
to 1997. Industry operating rates for cumene, which experienced the sharpest
drop in sales volume and price, were in the low 80 percent range in 1998. The
Company's average phenol sales price declined approximately 13 percent as
compared to 1997. The phenol industry operated at rates in the mid-90 percent
range. Looking forward, management expects phenol demand to continue its steady
growth in 1999; however, capacity additions scheduled for 1999 and 2000 will
cause further margin compression as industry supply increases. Phenol's
co-product, acetone, was also under price pressure during 1998. This trend will
more than likely continue as the current acetone industry capacity exceeds
forecasted demand.
 
    The methanol market has experienced a rapid decline in pricing and
profitability since the first quarter of 1998. Earnings for methanol declined
from $24.3 million in 1997 to a loss of $9.0 million in 1998. Substantial
increases in global supply created a significant imbalance between supply and
demand, resulting in a 39 percent decline in average pricing for 1998 as
compared to 1997. These market conditions have had a serious impact on
profitability for the domestic methanol industry as United States producers face
tighter competition from increased levels of low-cost imports. As a result, the
Company has temporarily shut down its operations of the methanol plant and is
supplying customers by purchasing methanol from offshore suppliers. The Company
is presently examining a range of options to enhance the value of the methanol
business and take advantage of the Company's customer base and extensive
distribution system.
 
    Selling and administrative expenses decreased $3.1 million in 1998 to $42.7
million, primarily as a result of reduced pension costs and lower profit-sharing
expense.
 
    In June 1998, the Company filed a shelf registration for the issuance of
$200.0 million of long-term bonds. Shortly after the filing, the Company entered
into an agreement to lock in interest rates on a portion of the bonds. During
the third quarter, treasury yields dropped to their lowest levels in 30 years,
while at the same time, investors' preference for treasury bonds reduced demand
for corporate bonds and limited the Company's ability to issue public debt. As a
result, the Company's plans to issue long-term bonds were postponed
indefinitely, and the interest rate lock agreements were terminated, resulting
in a one-time charge of $6.0 million after-tax or $0.19 per share in the third
quarter of 1998.
 
    Interest expense increased to $30.9 million for 1998, compared with $24.7
million for 1997. This increase primarily reflects a higher average debt balance
for 1998, as a result of the North American Plastics acquisition.
 
    Basic and diluted earnings per share for 1998 were lower due to the
reduction in net income but were favorably impacted by a reduction in the number
of outstanding common shares compared with the same period in 1997. This
reduction in shares was a result of the Company's stock repurchase program.
 
1997 COMPARED WITH 1996--Net sales in 1997 were $965.7 million, an increase of 8
percent from $896.2 million in 1996. Operating income also increased 8 percent
to $146.8 million in 1997 from $136.3 million in 1996. Diluted earnings per
share for 1997 were $2.39 on net income of $81.2 million as compared to diluted
earnings per share and net income for 1996 of $1.98 and $71.6 million,
respectively. Results for 1997 include a pretax gain of $8.6 million from the
sale of certain oil and gas properties, which resulted in an increase to net
income of $5.3 million, or $0.16 per share on a diluted basis.
 
    The Company generated the increase in net sales during 1997 from a 12
percent increase in sales volume, which was partially offset by a 4 percent
reduction in average sales price of the Company's products. Overall, the Company
operated its plants at 93 percent of capacity in 1997. Stronger demand led
 
                                       5
<PAGE>
to higher pricing for nearly all of the Company's products, with the exception
of caustic soda, which experienced a significant price decline. As for raw
materials, prices were up in 1997 with the exception of natural gas, where
prices were level with 1996. The Company's new cogeneration facility and air
separation plant, both completed in 1997 and located at the Plaquemine,
Louisiana complex, reduced the cost of previously purchased electricity,
nitrogen and oxygen.
 
    The Company's chlorovinyls business generated lower profits in 1997 as
compared with 1996 primarily as a result of a significant decline in the selling
price of caustic soda. Total sales volumes for chlorovinyls increased 7 percent;
however, the overall average selling price for chlorovinyls declined 11 percent
as sales price increases for most chlorovinyl products were overshadowed by the
drop in caustic soda pricing. Higher raw material costs also contributed to the
decline in profits from the chlorovinyls chain during 1997.
 
    Aromatic chemical products generated significantly higher operating income
for 1997 when compared to 1996. Sales volume for aromatics was up 23 percent in
1997 as the Company operated its aromatic plants at 98 percent of capacity. The
sales volume increase was also significantly impacted by the expansion of the
Company's cumene plant in 1996, which was fully operational throughout 1997.
Sales prices for cumene and phenol increased as demand for downstream markets
for phenol, primarily bisphenol-A and phenolic resins, strengthened during 1997.
Acetone, phenol's co-product, experienced a decline in pricing as the demand for
phenol exceeded the demand for acetone, creating a supply and demand imbalance
for acetone.
 
    Methanol operating income increased 145 percent to $24.3 million in 1997 as
continued strong demand and several industry outages resulted in higher sales
volumes and prices. The cost of natural gas, the primary cost component of
methanol, was basically the same for 1996 and 1997.
 
    Selling and administrative expenses increased $4.1 million in 1997 primarily
as a result of higher compensation expense relating to profit-sharing programs
and increased legal and environmental expenses.
 
    Interest expense increased $3.9 million in 1997 due to less interest being
capitalized in connection with capital expansion activity and a higher average
outstanding debt balance.
 
    Diluted earnings per share increased 21 percent in 1997 due to higher net
income and fewer shares outstanding resulting from the Company's share
repurchase program.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has continued to maintain a strong capital structure through
effective use of capital and the Company's ability to generate significant cash
flow from operations. A strong capital position has enabled Georgia Gulf to
invest in projects to enhance efficiency and increase productive capacity and to
repurchase a significant portion of the Company's common stock.
 
    Many of the Company's commodity products are expected to be in the trough
part of their pricing cycles during 1999. As management anticipates lower cash
flow from operations, investment in capital projects and stock repurchases will
be curtailed in order to maintain borrowings and available credit at manageable
levels. Management believes that cash provided by operations and the
availability of borrowings under the Company's revolving credit facility will
provide sufficient funds to support planned capital expenditures, dividends,
working capital fluctuations and debt service requirements.
 
    In 1998, Georgia Gulf generated $123.9 million from operating activities, up
$14.9 million from 1997. Major sources of cash flow from operating activities in
1998 were net income of $56.3 million, noncash provisions of $45.7 million for
depreciation and amortization and $28.0 million for deferred income taxes. Total
working capital at the end of 1998 was $65.1 million versus $57.5 million at the
end of 1997. The items affecting net income are discussed in the "Results of
Operations" section.
 
                                       6
<PAGE>
    Capital expenditures for 1998 decreased significantly to $25.9 million as
compared to $56.6 million for 1997. Georgia Gulf completed a major capital
expansion program in 1997, which included capacity expansions in the phenol,
acetone, VCM and vinyl compound plants. The Company also invested $99.9 million
for the acquisition of North American Plastics during 1998. As in 1998, capital
expenditures for 1999 will be directed toward certain environmental projects and
increased efficiency of existing operations. The Company estimates that total
capital expenditures for 1999 will approximate $25.0 million.
 
    Georgia Gulf repurchased and retired 2.3 million shares of its common stock
during 1998 at a total cost of $58.9 million. As of December 31, 1998, the
Company had authorization to repurchase an additional 5.2 million shares under
its stock repurchase program. The Company declared common stock dividends of
$0.32 per share or $10.0 million during 1998.
 
    Debt increased from $393.0 million at the end of 1997 to $459.5 million at
the end of 1998 as a result of the North American Plastics acquisition. Georgia
Gulf's debt portfolio primarily consists of a $100 million term loan, $100
million principal amount of 7 5/8% notes, $223.0 million outstanding under its
$350 million revolving credit facility and $36.5 million in other debt
agreements. The Company has interest rate swap agreements to fix the interest
rate on the term loan at a rate ranging from 6.71 percent to 7.04 percent. As of
December 31, 1998, the Company had availability of $127.0 million under its $350
million revolving credit facility.
 
    In 1997, Georgia Gulf generated $109.0 million from operating activities,
down $5.7 million from 1996. Major sources of cash flow from operating
activities in 1997 included net income of $81.2 million, noncash provisions of
$37.9 million for depreciation and amortization and $11.7 million for deferred
income taxes. During the third quarter of 1997, the Company sold certain oil and
gas properties for net proceeds of $16.5 million. The resulting book gain of
$8.6 million was reflected as a reduction to net income for purposes of
determining net cash provided by operating activities. Total working capital at
the end of 1997 was $57.5 million versus $49.4 million at the end of 1996.
 
    Net cash used in financing activities was $68.0 million in 1997 and was used
to fund repurchases of common stock in the amount of $59.3 million and dividends
of $10.7 million.
 
    Net cash used in investing activities was $40.1 million in 1997, and was
primarily attributable to capital expenditure requirements of $56.6 million for
several plant expansions, offset in part by $16.5 million generated from the
sale of certain oil and gas properties.
 
DISCLOSURES ABOUT MARKET RISK
 
    The Company is subject to certain market risks related to long-term
financing and related derivative financial instruments, foreign currency
exchange rates and commodity prices. The Company has policies and procedures to
mitigate the potential loss arising from adverse changes in these risk factors.
 
    INTEREST RATE SENSITIVITY--The table below is a "forward-looking" statement
that provides information about the Company's derivative financial instruments
and other financial instruments that are sensitive to changes in interest rates,
including interest rate swaps and financing obligations. The Company's policy is
to manage interest rates through use of a combination of fixed and floating rate
debt. The Company does not use interest rate swap agreements or any other
derivatives for trading purposes. For financing obligations, the table presents
principal cash flows and related weighted average interest rates by expected
maturity dates. For interest rate swaps, the table presents notional amounts and
weighted average interest rates by expected contractual maturity dates. Notional
amounts are used to calculate the contractual payments to be exchanged under the
contracts. Weighted average variable rates are based on implied
 
                                       7
<PAGE>
forward rates in the yield curve at the reporting date. The information and cash
flows are presented in U.S. dollars, which is the Company's reporting currency.

</TABLE>
 
    FOREIGN CURRENCY EXCHANGE RATE SENSITIVITY--Primarily all of the Company's
sales are denominated in U. S. dollars and it is the Company's policy to
purchase forward contracts to eliminate short-term exchange rate volatility for
foreign currency sales. The foreign currency exchange rate risk relates to
annual sales of less than $10.0 million and, accordingly, foreign currency
forward exchange agreements were not material at December 31, 1998.
 
    COMMODITY PRICE SENSITIVITY--The availability and price of the Company's raw
materials are subject to fluctuations due to unpredictable factors in global
supply and demand. To reduce price risk caused by market fluctuations, the
company from time to time executes raw material purchase contracts, which are
less than one year in duration. As of December 31, 1998, the fair value of these
raw material purchase contracts was a net payable of $704,000.
 
YEAR 2000 COMPUTER SYSTEMS COMPLIANCE
 
    The Company has recognized the need to ensure its operations will not be
adversely impacted by the Year 2000 date conversion situation common in many
data processing systems. All of the Company's financial reporting systems have
been acquired or developed within the past seven years. The installation of
these systems is complete, and testing indicates these systems are Year 2000
compliant. Process control software also controls the operation of many of the
Company's plants; this process control software was updated to Year 2000
compliant versions during 1998.
 
    The Company believes its remaining Year 2000 exposure exists primarily in
the areas of personal computers and with external partners. The remaining
exposure related to the personal computers will be addressed during the first
half of 1999. Third parties critical to the Company, both suppliers and
customers, were contacted during the first quarter of 1999 in order to develop
appropriate contingency plans, if necessary. The additional Year 2000 conversion
costs are not expected to be material.
 
FORWARD-LOOKING STATEMENTS
 
    This Annual Report and other communications to stockholders, as well as oral
statements made by representatives of the Company, may contain "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. These statements relate to, among other things, the Company's outlook
for future periods, supply and demand, pricing trends and market forces within
the chemical industry, cost reduction strategies and their results, planned
capital expenditures, long-term
 
                                       8
<PAGE>
objectives of management and other statements of expectations concerning matters
that are not historical facts.
 
    Predictions of future results contain a measure of uncertainty and,
accordingly, actual results could differ materially due to various factors.
Factors that could change forward-looking statements are, among others, changes
in the general economy, changes in demand for the Company's products or
increases in overall industry capacity that could affect production volumes
and/or pricing, changes and/or cyclicality in the industries to which the
Company's products are sold, availability and pricing of raw materials,
technological changes affecting production, difficulty in plant operations and
product transportation, governmental and environmental regulations and other
unforeseen circumstances. A number of these factors are discussed in the Annual
Report on Form 10-K and in the Company's other periodic filings with the
Securities and Exchange Commission.
 
INFLATION
 
    The most significant component of the Company's cost of sales is raw
materials which include basic commodity items. The cost of raw materials is
based primarily on market forces and has not been significantly affected by
inflation. Inflation has not had a material impact on the Company's sales or
income from operations.
 
ENVIRONMENTAL
 
    The Company's operations are subject to increasingly stringent federal,
state and local laws and regulations relating to environmental quality. These
regulations, which are enforced principally by the United States Environmental
Protection Agency and comparable state agencies, govern the management of solid
hazardous waste, emissions into the air and discharges into surface and
underground waters, and the manufacture of chemical substances.
 
    Management believes that the Company is in material compliance with all
current environmental laws and regulations. The Company estimates that any
expenses incurred in maintaining compliance with these requirements will not
materially affect earnings or cause the Company to exceed its level of
anticipated capital expenditures. However, there can be no assurance that
regulatory requirements will not change, and, therefore, it is not possible to
accurately predict the aggregate cost of compliance resulting from any such
changes.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                            GEORGIA GULF CORPORATION
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF CONSOLIDATION--The consolidated financial statements include
the accounts of Georgia Gulf Corporation and its subsidiaries (the "Company").
All significant intercompany balances and transactions are eliminated in
consolidation.
 
    NATURE OF OPERATIONS--The Company is a manufacturer and worldwide marketer
of chemical and plastic products. The Company's products are primarily
intermediate chemicals sold for further processing into a wide variety of
end-use applications including plastic pipe and pipe fittings, siding and window
frames, bonding agents for wood products, high-quality plastics, acrylic
sheeting and gasoline additives.
 
    USE OF ESTIMATES--Management of the Company is required to make estimates
and assumptions that affect amounts reported in the financial statements and
accompanying notes prepared in conformity with generally accepted accounting
principles. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS--The Company considers all highly liquid
investments with an original maturity of three months or less to be the
equivalent of cash for purposes of financial statement presentation.
 
    INVENTORIES--Inventories are valued at the lower of cost (first-in,
first-out) or market. Costs include raw materials, direct labor and
manufacturing overhead. Market is based on current replacement cost for raw
materials and supplies and on net realizable value for finished goods.
 
    PROPERTY, PLANT AND EQUIPMENT--Property, plant and equipment are stated at
cost. Maintenance and repairs are charged to expense as incurred, and major
renewals and improvements are capitalized. Interest expense attributable to
funds used in financing the construction of major plant and equipment is
capitalized. Interest expense capitalized during 1998, 1997 and 1996 was
$667,000, $2,802,000 and $4,826,000, respectively. Depreciation is computed
using the straight-line method over the estimated useful lives of the assets for
book purposes, with accelerated methods being used for income tax purposes.
 
    The estimated useful lives of the assets are as follows:

    GOODWILL--Goodwill of $86,725,000 was capitalized in connection with the
acquisition of North American Plastics, Inc. in 1998 (see Note 17). The goodwill
is being amortized over a 35-year period. Goodwill amortized to cost of sales
was $1,571,000 during 1998. The Company periodically evaluates goodwill for
impairment. In completing this evaluation, the Company estimates the future
undiscounted cash flows of the businesses to which goodwill relates in order to
ensure that the carrying amount of goodwill has not been impaired.
 
    OTHER ASSETS--Other assets comprised primarily deposits for long-term raw
material purchase contracts and debt issuance costs. Deposits are being
amortized as additional raw material cost over the remaining 16-year life of the
related contracts in proportion to raw material delivery. Debt issuance costs
are amortized to expense using the effective interest rate method over the term
of the related indebtedness.
 
    FINANCIAL INSTRUMENTS--The Company does not use derivatives for trading
purposes. Interest rate swap and cap agreements, forms of derivatives, are used
by the Company to manage interest costs on certain portions of the Company's
long-term debt (see Note 14). These financial statements do not reflect

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
temporary market gains and losses on derivative financial instruments, although
the estimated fair value is disclosed in Note 14. If subsequent to being hedged,
underlying transactions are no longer likely to occur, the related derivative
gains and losses are recognized currently as income or expense. Amounts paid or
received on the interest rate swap agreements are recorded to interest expense
as incurred. As of December 31, 1998 and 1997, interest rate swap agreements
were the only form of derivative financial instruments outstanding.
 
    ENVIRONMENTAL EXPENDITURES--Environmental expenditures related to current
operations or future revenues are expensed or capitalized consistent with the
Company's capitalization policy. Expenditures that relate to an existing
condition caused by past operations and that do not contribute to future
revenues are expensed. Liabilities are recognized when environmental assessments
or cleanups are probable and the costs can be reasonably estimated.
 
    EARNINGS PER SHARE--Basic earnings per share is computed based on the
weighted average number of common shares outstanding during the respective
periods. Diluted earnings per share is computed based on the weighted average
number of common shares outstanding, adjusted for dilutive potential issuances
of common stock.
 
    STOCK-BASED COMPENSATION--Stock-based compensation is recognized using the
intrinsic value method. Pro forma net income and earnings per share impacts are
presented in Note 9 as if the fair value method had been applied.
 
2. NEW ACCOUNTING PRONOUNCEMENTS
 
    Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income," which
requires additional disclosure and presentation of amounts comprising
comprehensive income beyond net income. The Company had no comprehensive income
amounts for the periods presented. As a result, the adoption had no impact on
the Company's reporting under generally accepted accounting principles.
 
    During June 1998, the Financial Accounting Standards Board issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities." This
Statement establishes accounting and reporting standards requiring that every
derivative instrument be recorded in the balance sheet as either an asset or
liability measured at its fair value and that changes in the derivative's fair
value be recognized currently in earnings unless specific hedge accounting
criteria are met. Special accounting for qualifying hedges allows derivative
gains and losses to offset related results on the hedged item in the income
statement and requires that a company must formally document, designate and
assess the effectiveness of transactions that receive hedge accounting. SFAS No.
133 is effective for fiscal years beginning after June 15, 1999, although
earlier adoption is permitted. SFAS No. 133 cannot be applied retroactively.
Management has not yet quantified the impact of adopting SFAS No. 133 on the
Company's financial statements.
 
3. RECEIVABLES
 
    The Company has entered into an agreement pursuant to which it sold a
percentage ownership interest in a defined pool of the Company's trade
receivables. As collections reduce accounts receivable included in the pool, the
Company sells participating interests in new receivables to bring the amount
sold up to the $50,000,000 maximum permitted by the agreement. The receivables
are sold at a discount, which

approximates the purchaser's financing cost of issuing its own commercial paper
backed by these accounts receivable. The ongoing costs of this program of
$2,807,000, $3,045,000 and $2,882,000 for 1998, 1997 and 1996, respectively,
were charged to selling and administrative expense in the accompanying
consolidated statements of income.

    The Company's credit agreement provides for an unsecured revolving credit
facility which permits borrowings of up to $350,000,000. The revolving credit
facility terminates and related outstanding loans, if any, are due in March
2000. As of December 31, 1998, the Company had availability to borrow up to
$127,000,000 under the terms of the revolving credit facility. An annual
commitment fee, which ranges from 0.10 percent to 0.25 percent (currently at
0.25 percent), is required to be paid on the revolving credit facility
commitment. The interest rate on the revolving credit facility is based on LIBOR
and averaged 5.97 percent and 5.98 percent for 1998 and 1997, respectively.
 
    The Company has a $100,000,000 unsecured term loan agreement with an average
rate of 6.99 percent for 1998 and 1997. The LIBOR-based variable interest rate
on the term loan has been fixed at a rate ranging from 6.71 percent to 7.04
percent using interest rate swap agreements. Required principal payments under
the term loan are $25,000,000 in June 2001 and $75,000,000 in June 2002.
 
    The Company has $100,000,000 principal amount of unsecured 7 5/8 percent
notes outstanding, which are due in November 2005. Interest on the notes is
payable semiannually on May 15 and November 15 of each year. The notes are not
redeemable prior to maturity.
 
    Under the credit agreement, term loan and notes, the Company is subject to
certain restrictive covenants, the most significant of which require the Company
to maintain certain financial ratios and to limit the amount of dividends and
repurchases of common stock. The Company's limit for dividends and repurchases
of common stock was $62,476,000 as of December 31, 1998.
 
    Cash payments for interest during 1998, 1997 and 1996 were $30,398,000,
$27,739,000 and $22,945,000, respectively.
 
8. STOCKHOLDERS' EQUITY
 
    In April 1990, the Company's stockholders approved a plan of
recapitalization, which resulted in a distribution to stockholders of
$864,733,000. The distribution for the recapitalization, net of certain tax
benefits, was charged against retained earnings.
 
    During 1998 and 1997, the Company repurchased 2,296,100 shares of its common
stock for $58,880,000 and 2,129,100 shares for $59,307,000, respectively. As of
December 31, 1998, the Company had authorization to repurchase up to 5,225,600
additional shares under the current common stock repurchase program, subject to
certain restrictions as described in Note 7.
 
    Each outstanding share of common stock is accompanied by a preferred stock
purchase right, which entitles the holder to purchase from the Company 1/100th
of a share of Junior Participating Preferred

Stock for $45.00, subject to adjustment in certain circumstances. The rights
expire on April 27, 2000 and may be redeemed by the Company for $0.01 per right
until ten days following the earlier to occur of the announcement that a person
or group beneficially owns 15 percent or more of the Company's outstanding
shares of common stock or the commencement of or announcement by any person or
group of an intent to commence a tender or exchange offer which would result in
any person or group beneficially owning 15 percent or more of the Company's
outstanding shares of common stock (the earliest of any such date, the
"Distribution Date"). The rights first become exercisable on the Distribution
Date. Subject to certain conditions, if a person or group becomes the beneficial
owner of 15 percent or more of the Company's outstanding shares of common stock,
each right will entitle its holder (other than certain acquiring persons) to
receive, upon exercise, common stock having a value equal to two times the
right's exercise price. In addition, subject to certain conditions, if the
Company is involved in a merger or certain other business combination
transactions, each right will entitle its holder (other than certain acquiring
persons) to receive, upon exercise, common stock of the acquiring company having
a value equal to two times the right's exercise price.
 
    In connection with the stock purchase rights described above, 30,000,000 of
the authorized shares of preferred stock are designated Junior Participating
Preferred Stock. If issued, the Junior Participating Preferred Stock would be
entitled, subject to the prior rights of any senior preferred stock, to a
dividend equal to the greater of $0.01 or that which is paid on the common
shares.
 
9. STOCK OPTION AND PURCHASE PLANS
 
    Options to purchase common stock of the Company have been granted to
employees under plans adopted in 1990 and 1998. Under the 1998 Equity and
Performance Incentive Plan approved by the Company's stockholders, the Company
may grant up to 2,000,000 options to employees and non-employee directors.
Option prices are equal to the closing price of the Company's common stock on
date of grant. Options vested ratably over a five-year period for the 1990
option plan and vest over a one- or three-year period for the 1998 Equity and
Performance Incentive Plan from the date of grant and expire no more than ten
years after grant.

9. STOCK OPTION AND PURCHASE PLANS (CONTINUED)
    The Company's stockholders have approved a qualified, non-compensatory
employee stock purchase plan, which allows employees to acquire shares of common
stock through payroll deductions over a twelve-month period. The purchase price
is equal to 85 percent of the fair market value of the common stock on either
the first or last day of the subscription period, whichever is lower. Purchases
under the plan are limited to 15 percent of an employee's base salary. In
connection with this stock purchase plan, 278,543 shares of common stock are
reserved for future issuances. Under this plan and similar plans, 228,585,
140,694 and 152,178 shares of common stock were issued at $13.36, $22.47 and
$22.47 per share during 1998, 1997 and 1996, respectively.
 
    The Company accounts for its stock-based compensation plans in accordance
with Accounting Principles Board opinion No. 25, "Accounting for Stock Issued to
Employees," and complies with SFAS No. 123, "Accounting for Stock-Based
Compensation," for disclosure purposes. Under these provisions, no compensation
was recognized in 1998, 1997 and 1996 for the Company's stock option plans or
its stock purchase plans.
 
    In accordance with the disclosure requirements of SFAS No. 123, the Company
is required to calculate the pro forma compensation cost of all stock options
and purchase rights granted after December 31, 1994, using an option pricing
model. Stock options granted in 1998 and stock purchase rights granted in
connection with the Company's stock purchase plan are subject to this
calculation.
 
    For SFAS No. 123 purposes, the fair value of each stock option and stock
purchase right for 1998, 1997 and 1996 has been estimated as of the date of the
grant using the Black-Scholes option pricing model with the following weighted
average assumptions for 1998, 1997 and 1996, respectively: risk-free interest
rates of 5.44 percent, 5.66 percent and 5.09 percent; dividend yields of 1.00
percent, 1.20 percent and 1.04 percent; and expected volatilities of 0.32, 0.23
and 0.30. The expected life of a right and option was assumed to be one year and
three years, respectively, for all years. Using these assumptions, the fair
market value of the stock option grants for 1998 was $3,493,000. Also using
these assumptions, the fair values of the stock purchase plan rights for 1998,
1997 and 1996 were $1,224,000, $977,000 and $1,062,000, respectively. Had
compensation cost been determined consistently with SFAS No. 123, utilizing the
assumptions detailed above, the Company's net income and earnings per common
share would have been the following pro forma amounts:

10. EMPLOYEE BENEFIT PLANS
 
    The Company has certain pension, savings and profit sharing plans that cover
substantially all of its employees. The expense incurred for these plans was
approximately $2,434,000, $3,798,000 and $4,522,000 for the years ended December
31, 1998, 1997 and 1996, respectively.
 
    Most employees are covered by defined contribution plans under which the
Company makes contributions to individual employee accounts and by defined
benefit plans for which the benefits are based on years of service and the
employee's compensation or for which the benefit is a specific monthly amount
for each year of service. The Company's policy on funding the defined benefit
plans is to contribute an amount within the range of the minimum required and
the maximum tax-deductible contribution.
 
    During 1998, the Company restructured several of its executive benefit plans
whereby certain plan benefits were replaced by new retirement agreements funded
by life insurance contracts. The elimination of the benefits under the previous
plans resulted in a reduction to pension expense for 1998 of $1,520,000. The
total expense related to the new agreements in 1998 was $693,000, which
represented the current year cost of the insurance contracts, net of the
increase in the cash surrender value of the contracts.
 
    In 1998, the Company adopted SFAS No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits." The Statement standardizes the
disclosure requirements for pensions and other postretirement benefits to the
extent practicable.
 
    On a weighted average basis, the following assumptions were used in the
accounting for the net periodic benefit costs and for the defined benefit plans:

11. INCOME TAXES (CONTINUED)
    Management believes, based on its history of operating earnings and
expectations for the future, that future taxable income will be sufficient to
fully utilize deferred tax assets at December 31, 1998.
 
12. COMMITMENTS AND CONTINGENCIES
 
    LEASES--The Company leases railcars, storage terminals, computer equipment,
manufacturing facilities and warehouse and office space under noncancelable
operating leases with varying maturities through the year 2010. Future minimum
payments under these noncancelable operating leases as of December 31, 1998 were
$23,301,000 for 1999, $16,735,000 for 2000, $6,575,000 for 2001, $5,469,000 for
2002, $4,317,000 for 2003 and $14,086,000 thereafter. Total lease expense was
approximately $25,734,000, $16,414,000 and $13,275,000 for the years ended
December 31, 1998, 1997 and 1996, respectively.
 
    The Company makes lease payments under an operating lease agreement for a
250-megawatt cogeneration facility at the Company's Plaquemine, Louisiana
complex. The total cost of assets covered by the lease is $115,000,000. The
initial lease term, which began in October 1997, is three years with options to
renew the lease for two one-year periods and to purchase the facility at its
estimated fair market value at any time during the lease term. The lease
provides for substantial residual value guarantees by the Company at the
termination of the lease if the then estimated fair value of the facility is not
recovered by the owner via sale to a third party.
 
    PURCHASE COMMITMENTS--The Company has certain take-or-pay raw material
purchase agreements with various terms extending through 2014. The aggregate
amount of the fixed and determinable portion of the required payments under
these agreements as of December 31, 1998 was $7,143,000 for each of the years
from 1999 through 2007 and 4,648,000 for the year 2008.
 
    LEGAL PROCEEDINGS--The Company is a party to numerous individual and several
class-action lawsuits filed against the Company, among other parties, arising
out of an incident that occurred in September 1996 in which workers were exposed
to a chemical substance on the Company's premises in Plaquemine, Louisiana. The
substance was later identified to be a form of mustard agent, a chemical which
is not manufactured as part of the Company's ordinary operations, but instead
occurred as a result of an unforeseen chemical reaction. The Company presently
believes there are approximately 2,000 plaintiffs, of which approximately 650
are workers claiming to have been on-site at the time of the incident. All of
the actions claim one or more forms of compensable damages, including past and
future wages, past and future physical and emotional pain and suffering, and
medical monitoring. The lawsuits were originally filed in Louisiana State Court
in Iberville Parish.
 
    Discovery has been occurring in these cases. The Company continues to
develop information relating to the extent of damages suffered, as well as
evaluating the merit of such claims, defenses available and liability of other
persons.
 
    In September 1998, the plaintiffs filed amended petitions that added the
additional allegations that the Company had engaged in intentional conduct
against the plaintiffs. These additional allegations raised a coverage issue
under the Company's general liability insurance policies. In December 1998, as
required by the terms of the insurance policies, the insurers demanded
arbitration to determine whether coverage is required for the alleged
intentional conduct in addition to the coverage applicable to the other
allegations of the case. The date for the arbitration has not yet been
established.

                            GEORGIA GULF CORPORATION
 
12. COMMITMENTS AND CONTINGENCIES (CONTINUED)
    As a result of the arbitration relating to the insurance issue, as permitted
by federal statute, the insurers removed the cases to United States District
Court in December 1998. The plaintiffs filed motions contesting the jurisdiction
of the federal court and seeking to remand the cases back to state court, and a
hearing on the issue was held in federal court on January 15, 1999. By order
entered March 2, 1999, the federal court denied the plantiff's motion to remand
the cases back to state court and retained federal jurisdiction.
 
    Settlements have been reached with approximately 260 of the original
workers, including the majority of those claimants believed to be the most
severely injured, and the settled cases have been or will be dismissed.
Additionally, settlements have been reached or are being negotiated with other
parties named as defendants whereby such parties have made, or are being
requested to make, contributions to the recoveries made by the plaintiffs.
Negotiations for the resolution of the remaining claims are continuing.
 
    Notwithstanding the foregoing, the Company is asserting and pursuing
defenses to the claims. Based on the present status of the proceedings, the
Company believes the liability ultimately imposed will not have a material
effect on the financial position or on results of operations of the Company.
 
    In addition, the Company is subject to other claims and legal actions that
may arise in the ordinary course of business. Management believes that the
ultimate liability, if any, with respect to these other claims and legal
actions, will not have a material effect on the financial position or on results
of operations of the Company.

13. SIGNIFICANT CUSTOMER AND EXPORT SALES
 
    SIGNIFICANT CUSTOMER--The Company has supply contracts, subject to certain
limitations, for a substantial percentage of Georgia-Pacific Corporation's
requirements for certain chemicals at prices approximating market. These supply
contracts have various expiration dates (depending on the product) from 1999
through 2003 and may be extended year-to-year upon expiration. The sales to
Georgia-Pacific Corporation under these supply contracts for the years ended
December 31, 1998, 1997 and 1996 amounted to approximately 11 percent, 12
percent and 15 percent of net sales, respectively. Receivables outstanding from
these sales were $6,866,000 and $11,807,000 at December 31, 1998 and 1997,
respectively.
 
    EXPORT SALES--Export sales were approximately 17 percent, 15 percent and 12
percent of the Company's net sales for the years ended December 31, 1998, 1997
and 1996, respectively. The principal international markets served by the
Company include Canada, Mexico, Latin America, Europe and Asia.
 
14. DERIVATIVE FINANCIAL INSTRUMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The Company entered into two interest rate swap agreements in June 1995, for
a total notional amount of $100,000,000 maturing in June 2002, to fix the
interest rate on the term loan. The fixed interest rate paid on the two interest
rate swap agreements was 6.31 percent, while the floating interest rate received
averaged 5.68 percent for 1998 and 1997. The Company also entered into an
interest rate swap agreement for a notional amount of $100,000,000 as a cash
flow hedge for the cogeneration facility operating lease agreement. This
interest rate swap agreement became effective in August 1997 and will mature in
August 2002 with a fixed interest rate of 5.88 percent. The floating interest
rate received averaged 5.62 percent and 5.73 percent for 1998 and 1997,
respectively.
 
    In June 1998, the Company filed a shelf registration with the Securities and
Exchange Commission for the issuance of $200,000,000 of long-term bonds. Shortly
after the filing, the Company entered into an agreement to lock in interest
rates on a portion of the long-term bonds. During the third quarter of 1998,
treasury yields dropped to their lowest levels in 30 years, while at the same
time, investors' preference for treasury bonds and weakened demand for corporate
bonds limited the Company's ability to issue longer term bonds. As a result, the
Company's plans to issue long-term bonds were postponed indefinitely and the
interest rate lock agreements were terminated, resulting in a pretax loss of
$9,500,000 in the third quarter of 1998.
 
    The following methods and assumptions were used to estimate the fair value
of each class of financial instrument:
 
    DEBT--The fair value of the 7 5/8% notes was based on quoted market prices.
The carrying amounts of the revolving credit loan and the term loan were assumed
to approximate fair value due to the floating market interest rates to which the
respective agreements are subject.
 
    INTEREST RATE SWAP AGREEMENTS--The fair value of the interest rate swap
agreements was estimated by obtaining quotes from brokers.

16. DISPOSITION
 
    In July 1997, the Company completed the sale of certain oil and gas
properties representing substantially all of the assets of Great River Oil & Gas
Corporation, a subsidiary of the Company. Net proceeds from this sale were
$16,477,000, on which the Company recorded a pretax gain of $8,600,000
($5,300,000, net of income taxes). Historically, the operating results for this
subsidiary have not been material to the financial statements of the Company.
 
17. ACQUISITION
 
    On May 11, 1998, the Company acquired all the issued and outstanding common
stock of North American Plastics, Inc., a privately held manufacturer of
flexible vinyl compounds with a production capacity of 190,000,000 pounds. North
American Plastics has two manufacturing locations in Mississippi and generated
approximately $90,000,000 in revenue in 1997. Its vinyl compounds are used in
wire and

17. ACQUISITION (CONTINUED)
cable for construction, automobiles and appliances, as well as various other
consumer and industrial products.
 
    The stock of North American Plastics was acquired in exchange for net cash
consideration of $99,902,000 plus the assumption of $500,000 in debt. The cash
portion of the acquisition was financed with proceeds from the Company's
existing revolving credit facility. The transaction was accounted for as a
purchase, and the consideration exchanged exceeded the fair market value of the
net tangible assets of North American Plastics by $86,725,000. This excess was
allocated to goodwill and is being amortized on a straight-line basis over a
period of 35 years. The results of operations of the acquired business have been
included in the Company's consolidated financial statements from the date of
acquisition. Pro forma results of operations have not been presented because the
effect of this acquisition was not significant.
 
18. SEGMENT INFORMATION
 
    SFAS NO. 131--"Disclosures about Segments of an Enterprise and Related
Information" became effective for fiscal year 1998 and for all succeeding
interim reporting periods. In accordance with the requirements of SFAS No. 131,
the Company has identified three reportable segments through which it conducts
its operating activities: chlorovinyls, aromatics and gas chemicals. These three
segments reflect the organization used by Company management for internal
reporting. The chlorovinyls segment is a highly integrated chain of products
which includes chlorine, caustic soda, vinyl chloride monomer and vinyl resins
and compounds. The aromatics segment is also vertically integrated and includes
cumene and the co-products phenol and acetone. The third product segment, gas
chemicals, includes methanol and, prior to July 1997, the Company's oil and gas
exploration activities. See Note 16 for a description of the Company's
disposition of its oil and gas operations.
 
    Earnings of industry segments exclude interest income and expense,
unallocated corporate expenses and general plant services, provision for income
taxes, and income and expense items reflected as "other income (expense)" on the
Company's consolidated statements of income. Intersegment sales and transfers
are insignificant.
 
    Identifiable assets consist of plant and equipment used in the operations of
the segment, as well as inventory, receivables and other assets directly related
to the segment. Corporate and general plant service assets include cash, certain
corporate receivables, data processing equipment and spare parts inventory as
well as property (i.e., land) on which the manufacturing plants are located. The
Company has no significant assets located outside of the United States.

                              REPORT OF MANAGEMENT
 
                            GEORGIA GULF CORPORATION
 
TO THE STOCKHOLDERS OF GEORGIA GULF CORPORATION:
 
    The accompanying consolidated financial statements of Georgia Gulf
Corporation are the responsibility of and have been prepared by the Company in
conformity with generally accepted accounting principles. The financial
information displayed in other sections of this 1998 Annual Report is consistent
with the consolidated financial statements.
 
    The integrity and the objectivity of the data in these consolidated
financial statements, including estimates and judgments relating to matters not
concluded by year-end, are the responsibility of management. The Company and its
subsidiaries maintain accounting systems and related internal controls,
including a budgeting and reporting system, to provide reasonable assurance that
financial records are reliable for preparing the consolidated financial
statements and for maintaining accountability for assets. The system of internal
controls also provides reasonable assurance that assets are safeguarded against
loss from unauthorized use or disposition and that transactions are executed in
accordance with management's authorization. Periodic reviews of the systems and
of internal controls are performed by the Company's internal audit department.
 
    The Audit Committee of the Board of Directors, composed solely of outside
directors who are not officers or employees of the Company, has the
responsibility of meeting periodically with management, the Company's internal
auditors and Arthur Andersen LLP, the Company's independent public accountants
that are approved by the stockholders, to review the scope and results of the
annual audit and the general overall effectiveness of the internal accounting
control system. The independent public accountants and the Company's internal
auditors have direct access to the Audit Committee, with or without the presence
of management, to discuss the scope and results of their audits, as well as any
comments they may have related to the adequacy of the internal accounting
control system and the quality of financial reporting.

                            GEORGIA GULF CORPORATION
 
REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF GEORGIA GULF CORPORATION:
 
    We have audited the accompanying consolidated balance sheets of Georgia Gulf
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1998
and 1997 and the related consolidated statements of income, changes in
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1998. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on the
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 financial position of Georgia Gulf Corporation and
subsidiaries as of December 31, 1998 and 1997 and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998 in conformity with generally accepted accounting principles.
