NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: BASIS OF PRESENTATION

        The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. The accompanying financial statements do reflect all the adjustments that, in the opinion of management, are necessary to present fairly the financial position, results of operations and cash flows for the interim periods reported. Such adjustments are of a normal, recurring nature. Our operating results for the three-month period ended March 31, 2002 are not necessarily indicative of the results that may be expected for the year ending December 31, 2002.

        These financial statements should be read in conjunction with the audited financial statements and notes to consolidated financial statements included in our annual report on form 10-K, filed with the Securities and Exchange Commission on March 29, 2002. That report includes a summary of our critical accounting policies on page 26. There have been no material changes in the accounting policies followed by us during fiscal year 2002 except for those changes described in Note 3.

NOTE 2: NEW ACCOUNTING PRONOUNCEMENTS

        During June 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 requires that a liability for an asset retirement obligation be recognized in the period incurred at fair value, if a reasonable estimate of fair value can be made. Any associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. We will adopt SFAS No. 143 on January 1, 2003. Management does not believe the adoption of SFAS No. 143 will have a material effect on our consolidated financial statements.

        During August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 144 clarifies financial accounting and reporting for assets held for sale, scheduled for abandonment or other disposal, and recognition of impairment losses related to the carrying value of long-lived assets. We adopted SFAS No. 144 on January 1, 2002. The adoption of SFAS No. 144 did not have a material effect on our consolidated financial statements.

NOTE 3: GOODWILL AND OTHER INTANGIBLE ASSETS

        We adopted SFAS No. 141, "Business Combinations," for all acquisitions made after June 30, 2001. This statement requires that all business combinations be accounted for by the purchase method and that intangible assets be recognized apart from goodwill if they meet certain criteria. Adoption of this statement did not have an effect on our financial statements.

        We adopted SFAS No. 142, "Goodwill and Other Intangible Assets," on January 1, 2002. Goodwill is the excess of cost of an acquired entity over the amounts specifically assigned to assets acquired and liabilities assumed in purchase accounting for business combinations. Effective January 1, 2002, with the adoption of SFAS No. 142, goodwill is no longer amortized. Prior to January 1, 2002 goodwill was being amortized on a straight-line basis, over a period of 35 years. As a result of the adoption of SFAS No. 142, goodwill will be tested for impairment annually, and will be tested for impairment between annual tests if an event occurs or circumstances change that would indicate the carrying amount may be impaired.

        Impairment testing for goodwill is done at a reporting unit level. Currently, we have identified three reporting units (electrovinyl, compounds, and aromatic chemicals) under the criteria set forth by SFAS No. 142. An impairment loss would generally be recognized when the carrying amount of the reporting unit's net assets exceeds the estimated fair value of the reporting unit. The estimated fair

4

value of a reporting unit is determined using earnings for the reporting unit multiplied by a price/earnings ratio for comparable industry groups. Prior to January 1, 2002, goodwill was tested for impairment in a manner consistent with property, plant and equipment and intangible assets with a definite life.

        As of January 1, 2002, the carrying value of goodwill was $77.7 million. All $77.7 million in goodwill is assigned to the compounds reporting unit. We performed the goodwill impairment test subsequent to the end of the first quarter by comparing the carrying value of the compounds reporting unit (as of December 31, 2001) as a multiple of earnings for comparable industry groups. The comparison indicated that the fair value determination of the compounds reporting unit exceeds the carrying amount by a sizable margin. We are able to conclude that there has been no impairment of the goodwill of the compounds reporting unit.

        Net income (loss) and earnings (loss) per share for the first quarter of 2002 and 2001, adjusted to include the non-amortization provisions of SFAS 142, net of tax, are as follows:

        (In thousands, except per share amounts)

NOTE 6: SEGMENT INFORMATION

        We have identified two reportable segments through which we conduct our operating activities: chlorovinyls and aromatics. These two segments reflect the organization which we use 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.

        Earnings of industry segments exclude interest income and expense, unallocated corporate expenses and general plant services, and provision for income taxes. Intersegment sales and transfers are insignificant.

NOTE 7: EARNINGS PER SHARE

        There are no adjustments to "Net income" or "Income from continuing operations" for the diluted earnings per share computations.

        The following table reconciles the denominator for the basic and diluted earnings per share computations shown on the condensed consolidated statements of income:

NOTE 8: SUPPLEMENTAL GUARANTOR INFORMATION

        Our payment obligations under our 10³/8% senior subordinated notes are guaranteed by GG Terminal Management Corporation, Great River Oil & Gas Corporation, Georgia Gulf Lake Charles, LLC and Georgia Gulf Chemicals & Vinyls, LLC, some of our wholly-owned subsidiaries (the "Guarantor Subsidiaries"). The guarantees are full, unconditional and joint and several. The following unaudited condensed consolidating balance sheets, statements of income and statements of cash flows present the financial statements of the parent company, our Guarantor Subsidiaries and our remaining subsidiaries (the "Non-Guarantor Subsidiaries").

        In connection with the acquisition of the vinyls business from CONDEA Vista Company on November 12, 1999, we essentially became a holding company by transferring our operating assets and employees to our wholly-owned subsidiary Georgia Gulf Chemicals & Vinyls, LLC. Provisions in our senior credit facility limit payment of dividends, distributions, loans and advances to us by our subsidiaries.

Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations.

RESULTS OF OPERATIONS

        Georgia Gulf manufactures and markets products through two highly integrated lines categorized into chlorovinyls and aromatic chemicals. Our primary chlorovinyl products include chlorine, caustic soda, vinyl chloride monomer ("VCM"), vinyl resins and vinyl compounds; our primary aromatic chemical products include cumene, phenol and acetone.

Three Months Ended March 31, 2002 Compared with Three Months Ended March 31, 2001

        Net Sales.    Net sales for the quarter ended March 31, 2002 were $260.9 million, a decrease of 29 percent compared to $368.9 million for the same period in 2001. This decrease was due to an 11 percent decrease in sales volumes and a decrease in the overall average selling price of 21 percent.

        Net sales of chlorovinyls for the first quarter of 2002 were $214.8 million, 24 percent lower than net sales for first quarter of 2001 of $281.1 million. This decrease was the result of a 4 percent decrease in sales volume and a 21 percent decrease in sales prices. The decrease in sales prices, when comparing the first quarter of 2002 to the first quarter of 2001, resulted from lowered pricing for vinyl resins and vinyl compounds as well as caustic soda.

        Net sales of aromatics for the first quarter of 2002 were $46.1 million, a decrease of 48 percent compared to $87.8 million for the same period in 2001. This decrease was the result of a 27 percent decrease in sales prices, primarily phenol, and 28 percent lower sales volumes, primarily cumene.

        Cost of Sales.    Cost of sales for the first quarter of 2002 was $235.6 million, a decrease of 33 percent compared to $351.5 million for the first quarter of 2001. The primary reason for this decrease was lower raw materials and energy costs. As a percentage of sales, cost of sales decreased to 90 percent in the first quarter of 2002 compared to 95 percent in the first quarter of 2001.

        Selling, General and Administrative Expenses.    Selling, general and administrative expenses were $11.4 million for the three months ended March 31, 2002, a decrease of 10 percent from $12.6 million for the same period in 2001. This decrease is primarily attributable to lower legal and professional fees, which more than offset an increase in accrued management incentives.

        Operating Income.    We had operating income in the first quarter of 2002 of $13.8 million compared to $4.7 million in the first quarter of 2001. The greater operating income is largely the result of improved vinyl resins shipments, lower raw materials costs and lower energy costs. The cessation of goodwill amortization improved operating income for the first quarter of 2002 by $0.6 million.

        Our chlorovinyls operating profit for the first quarter of 2002 was $18.1 million, an increase of 37 percent compared to $13.2 million for the same period in 2001. The most significant factors in this increase were greater sales volumes for vinyl resins and VCM coupled with lower energy costs and raw material costs that more than offset lower caustic soda selling prices.

        Our aromatics operating loss for the first quarter of 2002 was $0.9 million, which was an improvement when compared to an operating loss of $3.5 million in the first quarter of 2001. Lower raw materials costs and energy costs were able to largely compensate for the lower sales volumes and prices.

        Net Interest Expense.    Interest expense decreased to $12.9 million for the quarter ended March 31, 2002 compared with $15.1 million for the same period in 2001. This decrease was primarily attributable to the lower debt balance, as a result of a repayment of $47.8 million of debt, and lower interest rates.

13

        Provision (Benefit) for Income Taxes.    The provision for income taxes was $0.3 million for the first quarter of 2002 compared to a benefit from taxes of $3.7 million for the first quarter of 2001. Our effective tax rate was 36 percent for both quarters.

        Net Income (loss).    Net income for the first quarter of 2002 was $0.6 million compared to a net loss of $6.6 million in the first quarter of 2001. This was due to the factors discussed above. The cessation of goodwill amortization improved net income for the first three months of 2002 by $0.4 million, net of taxes.

LIQUIDITY AND CAPITAL RESOURCES

        For the three months ended March 31, 2002, we generated $18.2 million in cash from operating activities as compared to using $14.0 million in cash flow during the same period in 2001. The major source of cash flow for the first quarter of 2002 was the non-cash provision of $17.3 million for depreciation and amortization. Total working capital at March 31, 2002 was $91.8 million versus $87.6 million at December 31, 2001. Significant changes in working capital for the first quarter of 2002 included an increase in receivables, a decrease in the current portion of long-term debt, an increase in interest payable and an increase in accounts payable. Trade receivables increased as a result of increased sales. The increase in accounts payable was attributable to the timing of certain payments.

        Debt decreased by $13.6 million during the three months ended March 31, 2002 to $610.5 million. As of March 31, 2002, we had availability to borrow an additional $86.8 million under the revolving credit facility. Capital expenditures for the quarter ended March 31, 2002 were $3.9 million as compared to $8.7 million for the same 2001 period. Capital expenditures for 2002 are being directed toward normal repairs and maintenance, certain environmental projects and increased efficiency of existing operations. We estimate total capital expenditures for 2002 will approximate $25 million.

        We declared a dividend of $0.08 per share or $2.6 million during the first quarter of 2002.

        Under our senior credit facility and the indentures related to the 7⁵/8 percent notes and the 10³/8 percent notes, we are subject to certain restrictive covenants, the most significant of which require us to maintain certain financial ratios. Our ability to meet these covenants, satisfy our debt obligations and to pay principal and interest on our debt, fund working capital, and make anticipated capital expenditures will depend on our future performance, which is subject to general macroeconomic conditions and other factors, some of which are beyond our control. Management believes that based on current and projected levels of operations and conditions in our markets, cash flow from operations, together with our cash and cash equivalents of $8.9 million, and the availability to borrow an additional $86.8 million under the revolving credit facility, at March 31, 2002, will be adequate for the foreseeable future to make required payments of principal and interest on our debt, meet certain restrictive covenants which require us to maintain certain financial ratios, and fund our working capital and capital expenditure requirements. However, if the economic recovery does not continue as we anticipate during the remainder of the year, we may not be able to meet certain restrictive covenants and maintain compliance with certain financial ratios. In that event we would attempt to obtain waivers or covenant relief from our lenders. Although we have successfully negotiated covenant relief in the past, there can be no assurance we can do so in the future.

        Georgia Gulf Corporation conducts its business operations through its wholly owned subsidiaries as reflected in the consolidated financial statements. As Georgia Gulf Corporation is essentially a holding company, it must rely on distributions, loans and other intercompany cash flows from its wholly owned subsidiaries to generate the funds necessary to satisfy the repayment of its existing debt. Provisions in the senior credit facility limit payments of dividends, distributions, loans or advances to Georgia Gulf Corporation by its subsidiaries.

OUTLOOK

        Price increases in the first and second quarter for vinyl resins should help mitigate the impact of potentially lower aromatics volumes and rising raw materials costs and energy costs in the second quarter. The current economic forecast is for the economy to recover in the last half of this year, and if this occurs, we expect to see improved demand for our products.
