Great Lakes Chemical Corporation is a Delaware corporation incorporated in 1933 having its principal executive offices at 500 East 96th Street, Suite 500, Indianapolis, Indiana 46240. As used in this report, except where otherwise stated or indicated by the context, "Great Lakes" or "the Company" means Great Lakes Chemical Corporation and its consolidated subsidiaries.

Great Lakes is a customer-focused supplier of innovative specialty chemical solutions. The Company serves customers and markets through a global network of integrated sales, production, research, technical service and distribution facilities. The Company is organized into four global business units:

Polymer Additives—The Polymer Additives business unit is a leading developer, producer and marketer of bromine-, phosphorus- and antimony-based flame retardants; value-added antioxidants; UV absorbers; light stabilizers; performance additives and fluids; and optical monomers. These compounds are integrated into customer solutions that resist ignition and ensure the stability of products during processing or while in use.

Performance Chemicals—The Performance Chemicals business unit is a collection of individual businesses that apply their expertise in complex chemical synthesis, process development, manufacturing and toxicological testing to meet highly specific requirements for pharmaceutical, agrochemical and a wide range of industrial chemical applications.

Water Treatment—The Water Treatment business unit is the world's premier formulator of water treatment biocides and related specialty chemicals that make water better. This business unit extends innovative recreational water treatment products across the value chain to mass merchants, wholesale distributors, specialty store owners and retail customers. Its bromine-based biocides and proprietary polymer-based antiscalants and corrosion inhibitors target industrial customers in the global cooling process, wastewater, paper and desalination industries.

Energy Services and Products (OSCA)—OSCA provides specialized oil and gas well completion fluids, completion services and downhole completion tools to major oil companies and independent exploration and production companies, primarily in the Gulf of Mexico and in select international markets. Effective June 15, 2000, OSCA completed an initial public offering of its Class A common stock. As of December 31, 2001, Great Lakes had sold approximately 47% of its ownership in OSCA's outstanding common stock. Great Lakes has retained approximately 92% of the combined voting power of OSCA's outstanding voting stock through its ownership of all of the outstanding Class B shares, which have disproportionate voting rights.

On February 20, 2002, the Company announced that OSCA entered into a definitive merger agreement with BJ Services Company. Under the terms of the agreement, BJ services will acquire all of the outstanding shares of OSCA, including the Company's 53.2% holding, for $28.00 per share in cash.

The Company expects this transaction to close during the second quarter of 2002, subject to regulatory and other customary approvals. This transaction is expected to provide the Company with net proceeds of approximately $200 million in cash, all or a part of which will be used to reduce the Company's debt position.

There can be no assurances that the merger will be consummated in accordance with the terms of the merger agreement, if at all.

The essential raw material for bromine is brine from Company-owned wells in Arkansas and a sea water extraction plant in Europe. The Arkansas properties are located atop the Smackover lime deposits, which constitute a vast underground sea of bromine-rich brine. The 35-mile area between El Dorado and Magnolia, Arkansas, provides the best-known geological location for bromine production in the United States, and both major domestic bromine manufacturers are located in this area. Based on projected production rates, the Company's brine reserves are estimated to be adequate.

Other raw materials used in the business are obtained from outside suppliers through purchase agreements. The cost of raw materials is generally based on market prices, although risk management tools may be utilized, as appropriate, to mitigate short-term market price fluctuations. Other raw materials purchased include chlorine, caustic, hexafluoropropene, phenol, bisphenol A and antimony oxide.

The Company has multiple suppliers for most key raw materials and uses a variety of techniques such as the establishment of long-term relationships with suppliers and ongoing performance assessment as part of the total supplier selection process. In addition, the Company uses electricity and natural gas to meet its energy needs.

Great Lakes has a significant presence in foreign markets, principally Western Europe and Asia. Approximately one-third of the Company's assets and sales are outside the United States. The geographic segment data is set forth in Note 15: "Segment Information" of the Notes to Consolidated Financial Statements.

During the last three years, no single customer accounted for more than 10% of Great Lakes' total consolidated sales. The Company has no material contracts or subcontracts with government agencies. A major portion of the Company's sales are sold to industrial or commercial businesses for use in the production of other products. Some products, such as recreational water treatment chemicals and supplies, are sold to a large number of retail pool stores, mass merchandisers and distributors. Some export sales are marketed through distributors and brokers.

The Company's business does not normally reflect any material backlog of orders at year-end.

Great Lakes is in competition with businesses producing the same or similar products, as well as businesses producing products intended for similar use. The only other major producer of bromine and bromine derivatives in the United States competes with the Company in varying degrees, depending on the product. In addition, the Company competes with only one major overseas manufacturer of bromine and brominated products in the United States and elsewhere. Several small producers in the United States and overseas are competitors for several individual products. Furthermore, there are numerous manufacturers that compete with the Company by offering alternatives to Great Lakes products. In Polymer Stabilizers, the Company competes with a significantly larger supplier across the entire product line and with a number of smaller companies in individual product areas. Within Performance Chemicals, the Fluorine business competes with a global manufacturer producing similar products, as well as manufacturers with products intended for similar use. The Company's Water Treatment business competes with several manufacturers and distributors of swimming pool and spa chemicals.

Principal methods of competition are innovation, price, product quality and purity, technical services and the ability to deliver promptly. The Company is able to move quickly in providing new products to meet identified market demands. Management believes these factors, combined with highly qualified technical personnel, allow the Company to compete effectively.

The Company's products sold to the agricultural and swimming pool industries exhibit some seasonality, which is reflected in relatively higher sales and profits in the first half of each year. Seasonality also requires that the Company build inventories for rapid delivery at certain times of the year. In particular, the pool product season is strongest during the first six months, requiring a build-up of inventory at the beginning of the year. Customers are not permitted to return unsold material at the end of a season, except for certain negotiated arrangements with distributors and dealers.

The effect of the above items on working capital and liquidity requirements is not material.

The Company holds various patents and trademarks covering a number of its products and processes. While the Company believes these patents and trademarks offer significant commercial benefits, the Company's management does not believe any individual patent or trademark is of material

importance to the Company's business as a whole or that the success of the Company's business is dependent upon its portfolio of patents and trademarks.

Research and development expenditures are described in Note 14: "Research and Development Expenses" of the Notes to Consolidated Financial Statements.

The Company's operations are subject to various laws and regulations relating to maintaining or protecting the quality of the environment. Information regarding environmental compliance and contingencies is set forth under the "Environmental" caption in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and in Note 18, "Commitments and Contingencies," of the Notes to Consolidated Financial Statements.

The Company currently employs approximately 5,600 people, 40% of which are employed outside the United States. Approximately 320 employees are represented by collective bargaining agreements. The Company maintains good employee relations and has successfully concluded its most recent labor negotiations without a work stoppage. The Company, however, cannot predict the outcome of future contract negotiations.

The Company leases its principal executive offices in Indianapolis, Indiana, and owns its principal corporate facility in West Lafayette, Indiana. The Company operates 29 production facilities in 11 countries. The Company has distribution facilities at all of its manufacturing sites. Listed under "Item I. Business" above in the table captioned "Products and Services" are the production facilities by business unit. The Company's principal research facilities are in West Lafayette, Indiana; Decatur, Georgia; Lafayette, Louisiana; and Trafford Park (Manchester), U.K. Most principal locations are owned.

In addition, the Company owns or leases warehouses, distribution centers and space for administrative and sales offices throughout the world. All of the Company's facilities are in good repair, suitable for the Company's businesses and have sufficient capacity to meet present market demands at an efficient operating level.

The Company has been cooperating with the United States Department of Justice (DOJ) and the European Commission since the spring of 1998 in their respective investigations of the bromine and brominated products industry. Both investigations were initiated after the Company self-reported to those agencies certain business practices that raised questions under antitrust laws. As a result of the Company's cooperation, the Company and its current directors and employees have been accepted into the DOJ's amnesty program. The Company will be exempt from United States federal criminal prosecution and fines relating to the practices in question if the Company complies with certain conditions, including its full cooperation with the DOJ's investigation and policy regarding reasonable remedial efforts. Concurrently, the Company is seeking favorable treatment under a program in the European Union that also rewards self-reporting and cooperation.

The Company believes it has fully complied with all applicable conditions to date and has continued to cooperate with the DOJ in connection with certain follow-up matters arising out of the investigation, all of which are covered by the Company's acceptance into the amnesty program. The Company intends to continue full compliance with the DOJ and European Commission programs.

Participation in the above programs does not provide the Company with immunity from civil liability, including restitution claims. To date, 10 federal purported class action lawsuits and five California purported class actions have been filed against the Company, each claiming treble damages. These suits claim, among other things, that the Company conspired with others in violation of antitrust laws regarding the pricing of bromine and brominated products. The federal lawsuits have been consolidated in the District Court for the Southern District of Indiana. The plaintiffs filed a motion to certify a class of purchasers of three particular brominated products, and the Company has opposed the motion. In September 2001, the district court preliminarily certified a litigation class, and the Company promptly filed an application with the U.S. Court of Appeals for the Seventh Circuit in Chicago, requesting an interlocutory review and reversal of the class certification. That appeal was denied and the class was certified. The Company will continue to defend that litigation. The California cases remain stayed pending resolution of the federal cases.

On September 18, 2000, the Company's Energy Services and Products subsidiary, OSCA, was served with notice that a lawsuit was filed against it and other named defendants on September 1, 2000, in the District Court of Harris County, Texas. The action was brought by certain underwriting syndicates of Lloyd's of London who claim to be subrogated to the claim of their insureds, Newfield Exploration Company, Apache Oil Corporation, Continental Land & Fur and Fidelity Oil ("Plaintiffs"). The other defendants include High Pressure Integrity, Inc. and Chalmers, Collins & Alwell, Inc. On September 8, 2000, OSCA filed a lawsuit against the Plaintiffs and the other defendants in the United States District Court, Western District of Louisiana, Lafayette-Opelousas Division. Other actions have also been filed in connection with the same circumstances. All actions have now been consolidated into one proceeding in the United States District Court, Southern District of Texas.

The lawsuits relate to a blowout of a well situated off the shore of Louisiana in the Gulf of Mexico for which OSCA and others were engaged to perform specific workover operations. In the Texas case, Plaintiffs seek damages, interest and other costs in the approximate amount of $21.4 million, alleging that OSCA and the other defendants breached their contracts to perform workover operations and were negligent in performing those operations. OSCA alleges negligence against the Plaintiffs and other defendants and seeks damages, interest, costs and general and equitable relief. OSCA has amended its complaint to include Cardinal Wireline Service, which was performing wireline operations aboard the platform immediately before the blowout. OSCA has also filed a third party demand against its underwriters and insurance broker in support of coverage of claims asserted against OSCA in the Newfield matter.

OSCA has denied that it breached its contract or was negligent and intends to vigorously defend itself and to prosecute the merits of its claims. Mediation in the combined lawsuits is scheduled for March 5, 2002, and a trial date of March 14, 2002, has been set. On February 22, 2002, the court issued preliminary rulings in the case, one of which was partial summary judgment in favor of Newfield and against OSCA on the issue of breach of contract and another ruling was a dismissal of OSCA's claims against Cardinal Wireline Service. The court specifically stated, and OSCA believes, that this ruling is not dispositive as to whether OSCA's actions caused the blowout and therefore is liable for damages to Newfield. OSCA intends to defend the case vigorously. Management is unable to predict whether the outcome of the legal actions will have a material adverse effect on the results of operations in any particular period. However, management does not believe that the outcome will have a material adverse effect on the Company's consolidated financial position or liquidity (see Note 19).

West Lafayette Corporation, a wholly owned subsidiary of the Company, is a defendant in a judicial proceeding filed on August 30, 2000, by the State of Illinois in the Circuit Court of Illinois. The State is seeking penalties based on alleged failure to maintain air emission permits required by the State of Illinois and federal law. The Company is currently investigating the issue and has neither agreed to nor denied the allegations. However, the Company's management believes that the liability, if any, associated with such allegations will not have a material adverse effect on the Company.

Various other lawsuits and claims, other than those mentioned above, are pending against the Company and certain of its consolidated subsidiaries. While it is not possible to predict or determine the outcome of legal actions brought against the Company or the ultimate cost of these actions, the Company believes the costs associated with all such actions in the aggregate will not have a material adverse effect on its consolidated financial position, liquidity or results of operations. Furthermore, no director, officer or affiliate of the Company, or any associate of any director or officer is involved, or has a material interest in, any proceeding that could have a material adverse effect on the Company.

No matters were submitted to a vote of security holders during the quarter ended December 31, 2001.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following provides a review of the consolidated financial position of Great Lakes at December 31, 2001 and 2000, the consolidated results of operations for the three years ended December 31, 2001, and where appropriate, factors that may affect future financial performance. Please read this discussion in conjunction with the accompanying consolidated financial statements, notes and selected financial data.

Great Lakes Chemical Corporation is including the following cautionary statement to make applicable and take advantage of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995 with respect to any forward-looking statement made by, or on behalf of, the Company. Forward-looking statements generally may be identified by words such as "believes," "expects," "intends," "may," "will likely result," "estimates," "anticipates," "should" and other similar expressions, or the negative of such words or expressions. The factors identified in this cautionary statement are important factors (but do not necessarily constitute all important factors) that could cause actual results to differ materially from those expressed in any forward-looking statement made by, or on behalf of, the Company.

Where any such forward-looking statement includes a statement of the assumptions or bases underlying such forward-looking statement, the Company cautions that, while it believes such assumptions or bases to be reasonable and makes them in good faith, assumed facts or bases almost always vary from actual results, and the differences between assumed facts or bases and actual results can be material, depending upon the circumstances. Where, in any forward-looking statement, the Company, or its management, expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the statement of expectation or belief will result or be achieved or accomplished.

Taking into account the foregoing, certain factors, including but not limited to, those listed below may cause actual results to differ materially from those expressed in any forward-looking statement made by, or on behalf of, the Company.

Financial Reporting Release No. 60, which was recently released by the Securities and Exchange Commission, requires all companies to include a discussion of critical accounting policies or methods used in the preparation of financial statements. See Note 1 to Great Lakes' audited consolidated financial statements included elsewhere in this document for a summary of the significant accounting policies and methods used in the preparation of the consolidated financial statements. The Company believes the following are some of the more critical judgment areas in the application of accounting policies that currently affect the Company's consolidated financial condition and results of operations.

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The most significant estimates and assumptions relate to inventories, special charges, impairment of goodwill and intangible assets, income taxes, pensions and contingencies related to litigation and environmental matters. Actual amounts could differ significantly from these estimates.

The Company is required to state inventories at the lower of cost or market. In assessing the ultimate realization of inventories, the Company is required to make judgments as to future demand requirements and pricing and compare that with the current or committed inventory levels. Great Lakes recorded write-downs of inventory totaling $43.8 million in 2001 due to changes in strategic direction, such as discontinuing certain product lines, changes in market conditions, customer demand and unmarketable inventory. If future market conditions are less favorable than those predicted by management, additional inventory write-downs may be required.

The Company recorded special charges before reversals of $272.1 million, $66.4 million and $25.4 million in 2001, 2000 and 1999, respectively. These charges were in connection with detailed repositioning and restructuring plans that provided for a series of cost reduction initiatives to further streamline operations, strengthen the Company's competitive position and provide a platform for future growth. The charges associated with these plans included estimates for amounts related to asset impairments, employee severance costs, plant closures and related environmental costs, and the settlement of various contractual obligations resulting from repositioning and restructuring actions. Although the Company does not anticipate significant changes to these estimates, the actual costs may differ. When it is determinable that the actual costs differ from the original estimates, adjustments, either additional charges or reversals, are made to the remaining special charge reserves at that time.

The Company periodically evaluates long-lived assets, goodwill and other intangible assets for potential impairment indicators. Judgments regarding the existence of impairment indicators are based on legal factors, market conditions and operational performance of the Company's businesses. If impairment indicators are present, the Company is required to assess the recoverability of these assets. In assessing the recoverability of the Company's long-lived assets, goodwill and other intangible assets, the Company must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the respective assets. If these estimates or their related assumptions change in the future, the Company may be required to record additional impairment charges for these assets. Based upon assessments performed during 2001, the Company recorded $212.1 million of asset impairments including $128.8 million of impairment losses related to goodwill.

The Company accounts for income taxes in accordance with SFAS No. 109, "Accounting for Income Taxes," which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. SFAS No. 109 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

At December 31, 2001, the Company had deferred tax assets in excess of deferred tax liabilities of $65.1 million. At December 31, 2001 and 2000, management determined that it is more likely than not that $49.4 million and $12.2 million, respectively, of certain deferred tax assets will not be realized, requiring the Company to establish a valuation allowance for those amounts.

Each quarter, the Company evaluates the realizability of its deferred tax assets by assessing its valuation allowance and by adjusting the amount of such allowance, if necessary. The likelihood of realization is assessed by using the Company's forecast of future taxable income and available tax planning strategies that could be implemented to support realization of certain deferred tax assets.

Failure to achieve forecasted taxable income might affect the ultimate realization of certain deferred tax assets. Factors that may affect the Company's ability to achieve sufficient forecasted taxable income include, but are not limited to, increased competition, general economic conditions, a decline in sales or earnings, loss of market share or delays in product availability.

In addition, the Company operates within multiple taxing jurisdictions and is subject to audits in these jurisdictions. These audits can involve complex issues that may require an extended period of time for resolution. In management's opinion adequate provisions for income taxes have been made.

The Company sponsors various defined benefit pension plans that have significant pension benefit costs developed from actuarial valuations. Inherent in these valuations are key assumptions including discount rates, expected return on plan assets and rates of compensation increases. The Company is required to consider current market conditions, including changes in interest rates and plan asset investment returns, in determining these assumptions. At December 31, 2001, appropriate changes were made in the interest rate and rate of compensation increase assumptions for all plans. The Company currently expects pension costs to increase in 2002 by approximately $4 million to $5 million compared to 2001.

The Company is subject to legal proceedings, lawsuits and other claims related to environmental, labor, product and other matters. The Company is required to assess the likelihood of any adverse

judgments or outcomes related to these matters, as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies are made after careful analysis of each individual issue. At December 31, 2001, the Company had accrued $12.4 million and $59.1 million related to litigation and environmental liabilities, respectively, that management considers probable and for which a reasonable estimate of the liability can be made. These accruals may change in the future due to new developments in each matter or changes in approach, such as a change in settlement strategy, in dealing with these matters.

The following table sets forth the percentage relationship to net sales of certain income statement items for the Company's operations:

Net sales decreased 4.5% to $1,594.7 million from $1,670.5 million in the prior year. Volume growth in the Water Treatment business unit, which includes the effects of the acquisition of Aqua Clear LLC (Aqua Clear) in July 2000, and strong volume combined with moderate price increases in the Energy Services and Products (OSCA) business unit were offset by slowing end markets and lower selling prices in the Polymer Additives and Performance Chemicals business units. Additionally, unfavorable foreign exchange impacted all business units.

Gross profit margins decreased to 16.0% from 27.5% in the prior year. Excluding special charges, inventory write-downs and other charges (see Note 2) gross margins decreased to 21.3%, a 6.2% reduction from prior year. The primary factors contributing to this decline include external factors such as higher raw material and energy costs, severe price pressure in the Polymer Additives business unit and sharply lower demand in several key end markets. Additionally, these lower volumes and the Company's decision to operate plants at reduced capacities to lower inventory levels and improve cash flow had a negative impact on unabsorbed manufacturing costs throughout the year. Increased volume and a favorable product mix in the Energy Services and Products business unit partially offset these decreases.

Selling, general and administrative expenses increased $10.0 million to $266.1 million. As a percent of sales, selling, general and administrative expenses increased from 15.3% to 16.5%, excluding other

charges of $3.3 million (see Note 2). This increase reflects higher sales and marketing costs in the Water Treatment business unit, including the impact of the Aqua Clear acquisition, and increased information technology and legal expenses partially offset by several cost containment efforts undertaken by the Company.

Special charges of $267.1 million reflects $272.1 million of charges recorded during 2001 for a series of cost reduction initiatives undertaken by the Company, offset by $3.7 million of reversals of special charges taken in the second quarter of 2001 and $1.3 million of special charges taken in 2000. The net of the 2001 special charges and reversals is reflected in the consolidated statement of operations as a separate component of operating income.

Operating income (loss) was $(277.3) million compared to $140.2 million in the prior year. Excluding special charges, inventory write-downs and other charges (see Note 2), operating income was $76.7 million versus $203.6 million in the prior year. This decrease of $126.9 million year over year reflects the impact of lower sales volumes and prices, inventory reduction efforts and higher selling, general and administrative expenses.

Interest income (expense)—net increased $1.6 million to $(34.1) million in 2001 reflecting lower average cash balances during the year.

Other income (expense)—net increased $51.7 million from other expense—net of $(3.2) million in the prior year to $(54.9) million in 2001. Excluding other charges of $33.8 million (see Note 2), other income (expense)—net was $(21.1) million. The increase is primarily attributable to lower earnings from affiliates and an increase in minority interest expense associated with OSCA. In addition, in 2000, the Company recognized a gain from the disposition of an equity investment.

Income tax expense (credit) for the year ended December 31, 2001, amounted to a credit of $(67.4) million or (18.9)% compared to an expense of $37.9 million or 23% in the prior year. The 2001 effective income tax rate is lower than the Company's expected ongoing effective income tax rate of 31% due primarily to the increase in the valuation allowance, nondeductible goodwill write-offs related to the 2001 repositioning activities and the recognition of tax expense related to the change in strategy regarding the disposition of OSCA (see Note 19).

Net income (loss) was $(289.5) million or $(5.76) per share in 2001, as compared to $127.0 million or $2.42 per share in 2000. Net income (loss) excluding repositioning activities in both 2001 and 2000 was $21.3 million or $0.42 per share and $113.4 million or $2.16 per share, respectively.

Set forth below is a discussion of the operations of the Company's business segments: Polymer Additives, Performance Chemicals, Water Treatment and Energy Services and Products. Operating income, which is the income measure the Company uses to evaluate business segment performance, represents net sales less costs of products sold and selling, general and administrative expenses. The operating income data presented below is before the special charges recorded in 2001 and 2000. Each of the Company's segments uses bromine as a raw material in their production process. Bromine is transferred at cost to all business segments, except Energy Services and Products. Their cost is based upon a bromine supply agreement. In addition, assets used in the production of bromine are allocated to each business unit, with the exception of Energy Services and Products, based on the percentage of production consumed.

retardants with the acquisition of FMC Corporation's Process Additives Division (PAD). Polymer Additives provides its customers an array of integrated polymer additive solutions that are unsurpassed in the market and meet specific, well-defined customer needs in a variety of products including consumer electronics, computers and business equipment, automotive, furniture, fibers, wire and cable, household appliances, communications equipment, building and construction materials, packaging, textiles, polymers, cosmetics and optical monomers.

Polymer Additives		2001		2000
Net sales		$	581.7		$	690.1
Operating income			(70.8	)		52.4

Net sales decreased $108.4 million, or 15.7%, in 2001. A sharp decline in demand in several key end markets, particularly consumer electronics, automotive and information technology, affected both volume and price in 2001. The acquisition of the optical monomers business partially offset the decrease.

Operating income (loss) decreased $123.2 million to a loss of $(70.8) million for the year. Excluding special charges, inventory write-downs and other charges (see Note 2), operating income (loss) decreased $81.6 million to a loss of $(29.2). The decrease was attributable to lower sales levels, production cutbacks to align inventories with customer order patterns and higher raw material and energy costs in the first half of 2001. These items more than offset the cost savings resulting from productivity and cost savings initiatives.

The Performance Chemicals business unit is a collection of individual businesses and a global supplier of value-added products and services to broad and diverse markets that include pharmaceuticals, agrochemicals, biotechnology, electronics, telecommunications, information technology, photographic papers and films, rubber compounds, and soil, crop and structural pest control. Through its expertise in a wide range of chemical synthesis, process development, manufacturing and toxicological testing activities, the businesses within Performance Chemicals have become the choice for many companies to outsource their complex chemical production and service needs.

Performance Chemicals		2001		2000
Net sales		$	316.2		$	369.3
Operating income (loss)			25.5			90.8

Net sales decreased $53.1 million, or 14.4%, in the current year. This decrease was driven by significant volume declines in Fine Chemicals and lower than expected sales in the Fluorine business, predominately due to the sudden slow-down in information technology and telecommunication infrastructure spending.

Operating income decreased $65.3 million, or 71.9%, in the current year. Excluding special charges, inventory write-downs and other charges (see Note 2), operating income decreased $30.7 million, or 33.8%, to $60.1 million in the current year. This decrease in operating income reflects the impact of the sharply lower sales volumes in the Fine Chemicals and Fluorine businesses. Additionally, these lower sales volumes had a negative impact on unabsorbed manufacturing costs throughout the year. These items more than offset the record setting performance of toxicological testing subsidiary, WIL Research Laboratories, in 2001.

The Company's Water Treatment business unit, through its BioLab subsidiary, is the world's leading provider of recreational water care products to the consumer. By deploying a brand/channel

segmentation strategy, BioLab is able to maintain a strategic position in every important retail class of trade and leverage its resources. BioLab Water Additives, through its proprietary position in polymaleate chemistry, and as the world's foremost provider of bromine-based biocides, is a leading supplier of antiscalants, corrosion inhibitors, dispersants, antifoams, hydantoin derivatives, formulated oxidizers and desalination solutions.

Water Treatment		2001		2000
Net sales		$	507.0		$	474.5
Operating income			54.1			85.0

Water Treatment net sales increased 6.8% to $507.0 million in the current year. Increased market penetration, as well as the effects of the Aqua Clear acquisition drove the increase.

Operating income declined from $85.0 million in 2000 to $54.1 million in 2001. Excluding the impact of special charges, inventory write-downs and other charges (see Note 2), operating income decreased $20.2 million to $64.8 million in the current year. The positive impact of increased sales was more than offset by higher raw material costs and production cutbacks to lower inventory levels. Higher selling and marketing costs necessary to drive future growth in the mass market channel also contributed to the decrease.

The Energy Services and Products business unit (OSCA) is a leading provider of oil and gas well completion products and services. A pioneer in completion fluids, OSCA offers a comprehensive array of products and services including reservoir analysis, solids-free fluids, sand control, filtration, well stimulation, coiled tubing, custom downhole tool packages and marine well services. These products and services are available separately or as integrated systems. OSCA's products and services are focused on value-enhancing well completion activities that allow its customers to optimize the recovery of oil and gas. OSCA's singular focus and technological expertise enables it to compete successfully against its larger peers.

Energy Services and Products		2001		2000
Net sales		$	175.9		$	131.9
Operating income			18.0			12.5

Net sales for the year increased 33.4% to a record level of $175.9 million from $131.9 million in 2000. Led by technology, higher activity levels and the continued expansion of its business lines, OSCA increased its market penetration within a competitive environment.

Operating income increased 44.0% to $18.0 million in 2001. Record revenue, improved pricing and customer acceptance of new technologies were among the primary factors driving the increase in operating income.

Sales increased 11.3% to $1,670.5 million from $1,500.3 million in 1999. This growth was attributable to strong sales volume gains in all business units, including double-digit sales growth in the Water Treatment and Energy Services and Products business units. This volume growth, which includes the effects of acquisitions, was partially offset by lower selling prices in the Polymer Additives business unit and an unfavorable foreign exchange impact on all business units.

Gross profit increased 8.7% to $459.7 million from $423.1 million in the prior year, while gross margin decreased 0.7% from 28.2% to 27.5%. Volume growth and improved pricing and product mix in

the Performance Chemicals, Water Treatment and Energy Services and Products business units were offset by lower selling prices in Polymer Additives and higher energy and raw material costs.

Selling, general and administrative expenses increased $13.3 million to $256.1 million from $242.8 million in the prior year. This increase was a result of higher selling expenses related to the increased sales volumes and the effect of acquisitions. As a percent of sales, selling, general and administrative expenses decreased from 16.2% to 15.3% reflecting several cost containment efforts undertaken by the Company, including the 1999 and 2000 cost reduction initiatives.

Special charges of $63.4 million reflect the impact of a second quarter special charge totaling $66.4 million, adjusted downward by a $1.2 million change in estimate in the fourth quarter of 2000 to $65.2 million, related to a series of cost reduction initiatives undertaken in June 2000. Offsetting the 2000 special charge were certain reversals of the special charges taken in 1998 and 1999 totaling $1.8 million as explained more fully below. The net of the 2000 special charges and the reversals of prior year charges are reflected in the consolidated statement of operations as a separate component of operating income.

Operating income, excluding the effects of special charges, increased $23.3 million, or 12.9%, over the prior year. Operating income margins improved slightly, increasing from 12.0% to 12.2% for the year. Higher sales volumes and an improved product mix coupled with the cost containment efforts more than offset the effects of increased energy and raw material costs and lower selling prices in Polymer Additives.

Interest income (expense)—net increased $23.5 million in 2000 to $(32.5) million. The increase reflects higher average debt levels combined with higher interest rates during the year and lower levels of invested cash and cash equivalents.

Other income (expense)—net decreased from other income of $22.3 million in the prior year to other (expense) of $(3.2) million. This decrease reflects an increase in amortization expense due to acquisitions and an increase in minority interest expense resulting from the sale of subsidiary stock combined with a reduction from the prior year of approximately $10 million in the amount of gains recognized from the disposition of certain equity investments. These reductions were in part offset by an increase in earnings from unconsolidated affiliates over the prior year of $4.6 million.

Income taxes were $37.9 million, or 23.0%, compared to $35.8 million, or 20.4%, in the prior year. The 2000 effective tax rate is lower than the Company's expected ongoing effective tax rate of 31% due primarily to the nontaxable gain on the sale of subsidiary stock recorded in the second and third quarters of 2000. The lower effective tax rate in 1999 resulted from adjustments for previously provided taxes and structural changes made in the Company's foreign operations that resulted in generating a substantially higher percentage of income in lower tax rate jurisdictions.

Net income for 2000 was $127.0 million, or $2.42 per share. This compares to net income of $139.6 million, or $2.41 per share, for 1999. Excluding the after-tax effects of the gain on sale of subsidiary stock in 2000 and the effects of special charges on both 2000 and 1999, net income was $114.4 million, or $2.18 per share, and $151.4 million, or $2.61 per share, for 2000 and 1999, respectively.

A review of results of operations by business segment for 2000 compared with 1999 is as follows. The operating income data presented below is before the special charges recorded in 2000 and 1999.

The Polymer Additives business unit is a leading provider of flame retardants, polymer stabilizers and antimony-based derivatives and brings the most comprehensive product basket to the global marketplace. In 1999, the product platform expanded to include non-halogenated flame retardants with the acquisition of FMC Corporation's Process Additives Division (PAD). With the acquisition, Polymer Additives provides its customers an array of integrated polymer additive solutions that are unsurpassed in the market and meet specific, well-defined customer needs in a variety of products including computer and business equipment, consumer appliances, packaging, textile, building and construction, furniture and transportation.

Polymer Additives		2000		1999
Net sales		$	690.1		$	632.1
Operating income			52.4			78.0

Net sales increased $58.0 million, or 9.2%, in 2000. Continued recognition and acceptance of the Company's proprietary blends such as the No Dust Blends (NDB®) products, higher flame retardant volumes resulting from increased market penetration in Asia and the addition of sales related to the PAD acquisition drove the increase. The volume gains were partially offset by lower selling prices and unfavorable foreign exchange.

Operating income decreased $25.6 million, or 32.8%. This decrease was attributable to increased raw material costs and significantly higher energy costs coupled with lower selling prices associated with high-volume brominated flame retardants. These items more than offset the benefits of the higher sales volumes and cost savings resulting from productivity initiatives.

The Performance Chemicals business unit is a global supplier of value-added products and services to broad and diverse markets that include life sciences, agrochemicals, electronics and telecommunications. Through its expertise in a wide range of chemical synthesis, process development, manufacturing and toxicological testing activities, the businesses within Performance Chemicals have become the leading choice for many companies to outsource their complex chemical production and service needs. The Performance Chemicals business unit is a collection of individual businesses providing products and services that meet highly specific requirements for pharmaceutical, agrochemical and industrial chemical applications.

Performance Chemicals		2000		1999
Net sales		$	369.3		$	354.9
Operating income			90.8			78.7

Net sales for the year increased $14.4 million, or 4.1%. Strong volume gains across all product lines in the Fluorine group led to a record sales level for this business unit. WIL Research Laboratories' (WIL Research) expanded role in reproductive toxicological studies contributed to its 12.4% sales gain during the year. The gains reported by these businesses were partially offset by lower sales for Fine Chemicals and Brominated Performance Products.

Operating income increased $12.1 million, or 15.4%, for the year. In addition, operating margin for 2000 was 24.6% compared to 22.2% in the prior year. These record levels reflect the significant volume growth in Fluorine, increased sales and service mix improvements at WIL Research, improved pricing for methyl bromide and productivity initiatives throughout the businesses comprising Performance Chemicals.

The Company's Water Treatment business unit, through its BioLab subsidiary, is the world's leading provider of recreational water care products to the consumer. By deploying a brand/channel segmentation strategy, BioLab is able to maximize its market share and leverage its resources. During 1999, Water Treatment more than doubled its Industrial Water Division (renamed BioLab Water Additives) with the acquisition of FMC's water additives business. Through its proprietary position in polymaleate chemistry, and as the world's foremost provider of bromine-based biocides, BioLab Water Additives is a leading supplier of corrosion inhibitors, scale control and desalination solutions.

Water Treatment		2000		1999
Net sales		$	474.5		$	418.1
Operating income			85.0			73.1

The Water Treatment business unit completed another record year with net sales and operating income and margins all reaching record levels. Net sales increased $56.4 million, or 13.5%, reflecting consumer acceptance of important new technologies, continued market penetration, the acquisition of Aqua Clear Industries, LLC (Aqua Clear) in July 2000 and the addition of the BioLab Water Additives business acquired in August 1999. Operating income increased $11.9 million to $85.0 million from $73.1 million, a 16.3% increase. Operating margins improved from 17.5% to 17.9%. These improvements reflect the strength of the product portfolio, focused productivity efforts and the accretive effects of the BioLab Water Additives acquisition.

The Energy Services and Products business unit (OSCA) is a leading provider of oil and gas well completion products and services. A pioneer in completion fluids, OSCA today offers a comprehensive array of products and services including sand control, well stimulation, coiled tubing and custom downhole tool packages. These products and services are available separately or as integrated systems. OSCA's products and services are focused on value-enhancing well completion activities that allow its customers to optimize the recovery of oil and gas. OSCA's singular focus and technological expertise enable it to compete successfully against its larger peers.

Energy Services and Products		2000		1999
Net sales		$	131.9		$	95.2
Operating (loss) income			12.5			(8.5	)

Net sales increased in 2000 by $36.7 million, or 38.6%, to $131.9 million, a record year. This performance demonstrates OSCA's ability to grow by leveraging the investment it has made in capacity, coupled with its increased market penetration in Brazil and Venezuela and higher levels of exploration and development activities driven by higher commodity pricing for crude oil and natural gas.

Operating income improved to $12.5 million compared to an operating loss of $(8.5) million in the prior year. Volume increases, improved pricing and a better product mix resulting from OSCA's pull-through leverage were the primary factors driving the significant improvement in operating income.

Cash and cash equivalents at December 31, 2001, were $71.6 million, which represents a decrease of $151.1 million from $222.7 million at year-end 2000.

Cash provided by operating activities was $173.9 million in the current year compared to $205.8 million in the prior year. Despite the significant decrease in operating income, the Company was able to substantially offset this decrease with significant improvements in working capital including

improvements (excluding the impact of foreign currency translation and noncash charges) in accounts receivable and inventories of $75.8 million and $54.6 million, respectively.

Net cash used for investing activities amounted to $173.9 million in 2001 compared to $107.2 million in the prior year. This increase reflects similar amounts being utilized for capital expenditures and acquisitions of approximately $197 million in both years that is offset by the cash proceeds received from the sale of OSCA stock, which totaled $11.7 million in 2001 and $90.2 million in 2000.

Capital expenditures (excluding acquisitions) in 2001 of $166.2 million were slightly higher than the $157.0 million spent a year ago. Major projects for which capital expenditures were incurred include the replacement of bromine extraction towers at the Company's El Dorado, Arkansas facility; the expansion of a Polymer Additives manufacturing site in Italy in order to achieve backward integration of a key raw material; and the expansion of Water Treatment's Lake Charles, Louisiana, plant. Capital spending is expected to decrease significantly in 2002 with expenditures estimated to be in the $95 million to $100 million range. Future capital spending, including amounts for environmental and safety projects, is expected to be financed primarily with cash provided by operating activities and, if necessary, with available debt financing. Great Lakes continues to evaluate potential acquisitions of facilities and/or businesses, particularly in the segments in which the Company currently competes.

Cash used for financing activities was $171.6 million in 2001 as compared to $344.8 in 2000. The $171.6 million in 2001 results primarily from repayments of long-term borrowings of $160.9 and cash dividends of approximately $16 million. This compares to repayments of long-term borrowings in the prior year of $198.0 million, repurchases of common stock of $135.1 million and cash dividends of approximately $17 million.

The Company anticipates that cash provided by operating activities in the future will be sufficient to fund its operating expenses, debt service obligations, dividend payments to common shareholders and capital expenditures. In addition, as described in Note 19 to the consolidated financial statements, the Company expects to receive net cash proceeds from the sale of OSCA of approximately $200 million in the second quarter of 2002. All or part of the proceeds will be used to reduce the Company's debt position.

Long-term debt, less current portion, decreased $160.4 million to $527.8 million from $688.2 million at the end of the prior year reflecting the cash activity noted above and the decrease in the cash and cash equivalents. Stockholders' equity decreased $336.2 million from 2000 due primarily to the 2001 net loss of $289.5, foreign currency translation adjustments of $27.4 million and dividends of $15.9 million. As a result of these changes the Company's long-term debt, including the current portion, as a percentage of total capitalization at December 31, 2001, increased to 46.8% compared to 42.2% at December 31, 2000.

On October 4, 2001, the Company established two unsecured revolving credit facilities with various financial institutions under which it may borrow up to $237.5 million under each facility for a total of up to $475.0 million. One facility has a 364-day term and the other facility has a five-year term. Both are used to support the commercial paper program and for general corporate purposes. The 364-day agreement may be renewed annually, subject to certain conditions. Both facilities contain covenants, which include requirements for a ratio of debt to EBITDA ranging from 3.5 to 1 in 2001 to a maximum of 5.15 to 1 for the first three quarters of 2002, as defined in the agreements. The Company's forecasted cash flow, including the cash received from the sale of OSCA (see Note 19) is expected to be sufficient to allow the Company to meet these covenants in the future. These facilities replaced the $600.0 million revolving credit facility that expired on October 4, 2001.

The Company has traditionally utilized commercial paper borrowings as its primary source of external financing. However, during 1999 the Company moved to lock-in historically low long-term interest rates by selling $400 million of 7% notes due July 15, 2009. Proceeds from the sale of the notes were used to replace a portion of the commercial paper borrowings and to fund acquisitions. The notes were sold under a shelf registration process. Under this process, the Company filed a Registration Statement on Form S-3 with the Securities and Exchange Commission and may sell various debt securities, common stock or rights or warrants to purchase common stock individually or in combination up to $750 million. The amount remaining on the registration statement is $350 million. The registration provides the Company with increased flexibility to finance its growth. The amount and timing of any borrowings will depend on the Company's specific cash requirements.

At December 31, 2001, the Company's senior debt rating was A/A2 and its commercial paper rating was A1/P1. Effective January 11, 2002, Standard and Poor's lowered the Company's senior debt rating to A- and its commercial paper rating to A2. Moody's maintains its current debt rating with a "negative" outlook. These events are not expected to have a significant impact on the Company's liquidity.

At December 31, 2001, the Company had guaranteed $19.1 million of debt of an unconsolidated affiliate.

Total stockholders' equity was $613.5 million, or $12.22 per share, at December 31, 2001, compared to $949.7 million, or $18.88 per share, at the end of 2000. This decrease reflects the current year net loss of $289.5 million, the $27.4 million negative impact of the foreign currency translation adjustments, net of related deferred income taxes, included in accumulated other comprehensive income (loss), dividends of $15.9 million and $3.4 million of other items. During 2001, the Company had common stock share repurchases, of approximately 0.1 million shares of common stock at an average price of $22.19 per share. At December 31, 2001, a total of 2.8 million shares remain available for repurchase under existing authorizations by the Board of Directors. Management continues to analyze share repurchases as cash flow, market conditions and investment opportunities warrant.

On June 27, 2001, the Company's Board of Directors approved a detailed repositioning plan that provided for a series of cost reduction initiatives to further streamline operations, strengthen the Company's competitive position and continue to provide a strong platform for future growth. Additionally, on September 15 and December 6, 2001, the Company's Board of Directors approved an additional series of cost reduction initiatives developed to minimize the effects of then current economic conditions. The major components of these repositioning plans included the consolidation of certain Polymer Additives and Fine Chemicals operations, resulting in three planned plant closures; elimination of approximately 630 manufacturing, research and development, sales and other management positions; and the impairment of certain underperforming and nonstrategic long-lived assets, including goodwill. The Company expects to realize approximately $47 million in annual pretax savings as a result of these repositioning actions.

The special charges related to this repositioning plan totaled $272.1 million, $203.8 million after income taxes, or $4.05 per share, for the year ended December 31, 2001. The special charges consisted of $212.1 million of asset impairments, including $83.3 million for fixed asset impairments and $128.8 million of impaired goodwill; $31.6 million of severance costs; $20.4 million for plant closure and environmental costs; and $8.0 million of other costs.

Net special charges for the year ended December 31, 2001, totaled $267.1 million, $200.1 million after income taxes or $3.98 per share. This reflects the $272.1 million of charges recorded in 2001 offset by a reversal of $3.7 million related to changes in estimates in the 2001 special charge and certain reversals of the special charges taken in 2000 totaling $1.3 million, as detailed below. The net effect of the special charge reversals after income taxes was $3.7 million, or $0.07 per share. The net of the 2001 special charges and reversals are reflected in the 2001 consolidated statement of operations as a separate component of operating income. Additional information regarding the 2001 special charges is provided in Note 2 to the consolidated financial statements.

As of December 31, 2001, $47.4 million of the $272.1 million charge remains. The major components of this remaining reserve relate to severance and plant closure and environmental costs for the three plant closures and the shutdown of two unprofitable product lines. The majority of the severance costs are expected to be paid out by the end of 2002 and the plant closure and environmental costs by 2005.

Furthermore, during 2001 the Company recorded lower of cost or market inventory write-downs totaling $43.8 million. These write-downs were recorded as a component of cost of products sold and resulted primarily from significant declines in forecasted revenue for the Polymer Additives business unit and the Fine Chemicals business, which is part of the Performance Chemicals business unit. In addition, the Water Treatment business incurred lower of cost or market valuation adjustments due to unsuccessful promotional inventory buys.

Additionally, the Company recorded a $24.5 million liability for environmental remediation costs, $8.7 million for plant shutdown operating inefficiencies, an $8.0 million cumulative U.K. pension liability, $0.9 million of accounts receivable write-offs and $1.0 million of contract cancellation costs. These items amounted to $43.1 million and were recorded in the 2001 consolidated statement of operations as follows: $39.8 million to cost of products sold and $3.3 million as a component of selling, general and administrative expenses.

Certain other charges have also been recorded during 2001. These charges, which net to $33.8 million, include $11.6 million related to the write-off of an uncollectible note receivable from the sale of a previously owned business; $10.7 million for losses incurred on fixed asset replacement activities, primarily at one of the Company's U.S. plants; $13.4 million of increases in litigation accruals resulting from estimated settlement amounts on outstanding litigation matters; a $(3.2) million net foreign exchange gain arising from the repatriation of cash from a foreign subsidiary partially offset by a loss from a fair value adjustment on an intercompany loan of a foreign subsidiary; and $1.3 million of other costs. All of these charges are reflected in the 2001 consolidated statement of operations as a component of other income (expense)—net.

Chemicals locations, including sites in the United States, United Kingdom and Germany. The special charges related to this repositioning plan totaled $66.4 million, $49.5 million after income taxes, or $0.95 per share, for 2000. The $66.4 million special charge consisted of $43.8 million for asset impairments, $16.4 million for severance costs and $6.2 million for plant closure and environmental costs. The Company has realized approximately $20 million in annual pretax savings as a result of this repositioning. Additional information regarding the 2000 special charges is provided in Note 2 to the consolidated financial statements.

Net special charges for the year ended December 31, 2000, totaled $63.4 million. This reflects the $66.4 million charge offset by a reversal of $1.2 million related to a change in estimate in the 2000 special charge and certain reversals of the special charges taken in 1999 and 1998 totaling $1.8 million. The net effect of the special charge reversals after income taxes was $2.0 million, or $0.04 per share. The net of the 2000 special charges and reversals are reflected in the 2000 consolidated statement of operations as a separate component of operating income.

The 2000 repositioning plan has now been substantially completed with only $4.7 million of the original $66.4 million remaining. The primary component of this remaining reserve, or $4.3 million, relates to costs yet to be incurred for the closure of a brine pond in El Dorado, Arkansas. All of the 2000 remaining reserves are expected to be fully utilized by 2003.

In the first quarter of 1998, the Board of Directors appointed a new chief executive officer, and over the following months a new senior management team was assembled. Beginning in the third quarter of 1998, the Company began work on a plan to fundamentally alter how the Company conducts business around the world and to improve operating income by repositioning the business to enhance competitiveness and productivity and increase responsiveness to customer needs. A formal repositioning plan to accomplish these goals was approved by the Board of Directors in 1998. In addition, in the fourth quarter of 1999, the Board of Directors took certain additional actions to further streamline the Polymer Additives business unit, to provide a more flexible data processing solution for the Company's manufacturing operations and to write-down certain assets formerly used in Energy Services and Products' Mexico-based environmental business. The plan was developed to increase the Company's focus on its core specialty chemicals businesses and to position these operations to achieve higher growth and profitability.

Accordingly, the Company recognized a special charge of $25.4 million, $16.5 million after income taxes, or $0.29 per share, during 1999. Offsetting this charge were certain reversals of the special charges taken in 1998 totaling $7.2 million, $4.7 million after income taxes, or $0.08 per share. The net of the 1999 special charges and reversals are reflected in the 1999 consolidated statement of operations as a separate component of operating income. Additional information regarding the 1999 special charges is provided in Note 2 to the consolidated financial statements.

As of December 31, 2001, the 1999 component of the repositioning plan has been completed. The 2001 activity related to the 1999 special charges includes a reversal of $0.4 million due to changes in estimate of the 1999 charge and was recorded in the second quarter of 2001.

Cash outlays for all remaining special charge reserves are expected to be substantially complete by the end of 2005. Operating cash flows are expected to be sufficient to fund the remaining repositioning activities.

On February 14, 2001, the Company finalized its acquisition of an optical monomers business from Akzo Nobel Polymer Chemicals LLC for approximately $30 million in cash. As part of the Polymer Additives business unit, Great Lakes' Optical Monomers business operates at a leased manufacturing site in Pasadena, Texas, and has sales and support networks throughout the United States, Europe and

Asia. This acquisition was accounted for using the purchase method of accounting with its results of operations included since the date of acquisition.

On May 3, 1999, the Company completed the acquisition of NSC Technologies from Monsanto Company for approximately $125 million in cash. NSC Technologies develops, manufactures and sells chiral pharmaceutical intermediates and select bulk actives to pharmaceutical companies. The business' core chiral expertise in unnatural amino acids provides a broad molecular platform from which it develops novel, high-value-added intermediates and bulk actives for antiviral, cardiovascular and oncology therapeutic drugs. NSC Technologies is part of the Fine Chemicals group of the Performance Chemicals business unit.

On August 2, 1999, the Company completed the acquisition of FMC Corporation's Process Additives Business (PAD) for $162 million in cash. PAD is a world leader in the production of phosphate ester flame retardants, flame retardant fluids and lubricant additives, as well as a leading supplier of specialty water treatment chemicals used in industrial applications and desalination. The transaction broadened Great Lakes' Polymer Additives business unit and more than doubled the industrial segment of the Water Treatment business unit. Manufacturing operations are in Nitro, West Virginia, and Trafford Park (Manchester), U.K.

The acquisitions listed above were funded with available cash and borrowing capacity.

Effective June 15, 2000, the Company sold 40% of its ownership in OSCA, Inc. (OSCA), the Company's wholly owned Energy Services and Products subsidiary, through an initial public offering. Net proceeds of approximately $79 million from the initial sale were paid to the Company by OSCA to satisfy indebtedness. The initial sale resulted in a $51.9 million gain to the Company, which was recognized in the second quarter of 2000. Subsequently, on July 13, 2000, the over-allotment option granted to the underwriters was exercised and resulted in an additional $12 million of net proceeds. The over-allotment exercise resulted in an additional gain to the Company of $8.5 million, which was recorded in the third quarter of 2000. The initial sale and the over-allotment option exercise resulted in the Company selling a total of 43.4% of its ownership interest in this subsidiary.

In addition, in each of the first and second quarters of 2001, the Company sold 250,000 shares of OSCA Class B common stock pursuant to Rule 144 under the Securities Act of 1933, for a total of 500,000 shares being sold for the year ended December 31, 2001. The terms of these transactions provided that upon the sale of these Class B shares, the shares were automatically converted to OSCA Class A common stock. Net proceeds were $5.4 million and $6.3 million and the related taxable gains were $4.2 million and $5.2 million for the first and second quarters of 2001, respectively.

The combination of the initial sale, the over-allotment option exercise and the Rule 144 sales has resulted in the Company selling a total of 46.8% of its ownership interest in this subsidiary. OSCA continues to be included in the consolidated financial position and results of operations due to the Company's ability to exert significant influence over OSCA as a result of its continuing ownership and voting interest.

On February 20, 2002, the Company announced that OSCA entered into a definitive merger agreement with BJ Services Company. Under the terms of the agreement, BJ Services will acquire all

of the outstanding shares of OSCA, including the Company's 53.2% holding, for $28.00 per share in cash.

The Company expects this transaction to close during the second quarter of 2002, subject to regulatory and other customary approvals. This transaction is expected to provide the Company with net proceeds of approximately $200 million in cash, all or part of which will be used to reduce the Company's debt position.

The Company is subject to various U.S. and international federal, state and local environmental, health and safety laws and regulations. The Company is also subject to liabilities arising under the Comprehensive Environmental Response Compensation and Liability Act ("CERCLA"), the Resource Conservation and Recovery Act ("RCRA") and similar state and international laws that impose responsibility for remediation of hazardous substances and hazardous waste constituents released into the environment.

The Company provides reserves for environmental liabilities that management considers probable and for which a reasonable estimate of the liability can be made. After a review of the Company's operating sites in the third quarter of 2001, management determined that a third quarter charge of $24.5 million was appropriate to increase reserves for environmental liabilities. Accordingly, the Company's reserves for environmental liabilities, which are recorded in other noncurrent liabilities, were approximately $59.1 million and $17.4 million at December 31, 2001 and 2000, respectively. These liabilities include environmental costs associated with the 2001 and 2000 special charges. While it is not possible to predict or determine the outcome of actions brought against the Company or the ultimate cost of environmental matters, management believes that the ultimate cost, if any, in excess of the amounts already provided is not likely to have a material adverse effect on its consolidated financial position or results of operations.

The Company's operating costs relating to environmental compliance and safety charged directly to expense were approximately $40 million in 2001 compared to approximately $36 million and $27 million in 2000 and 1999, respectively. These amounts include approximately $3 million, $4 million and $2 million for expenditures on capital equipment in 2001, 2000 and 1999, respectively.

Inflation has not been a significant factor for the Company over the last several years. Management believes that the effect of inflation on Company operations will continue to be moderate over the next several years.

Effective January 1, 1999, member states of the European Economic and Monetary Union converted to a common currency known as the euro. From that date until January 1, 2002 (the transition period), either the euro or a participating country's present currency was accepted as legal tender, with the country's existing currency to be completely removed from circulation between January 1, 2002, and July 1, 2002.

The Company has been preparing for the introduction of the euro since 1999. The Company's plan for phase-out of the existing currencies complied with legal requirements and also was coordinated with the phase-out plans of the Company's vendors, distributors and customers. The phase-out plan and introduction of the euro required the conversion of information technology systems; recalculation of currency risk; recalibration of derivatives and other financial instruments; evaluation and action, if needed, regarding the continuity of contracts; and modification of processes for preparing tax,

accounting, payroll and customer records. Great Lakes completed a full implementation of the euro in December 2001.

In October 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (FAS 144), which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," and the accounting and reporting provisions of Accounting Principles Board Opinion No. 30, "Reporting the Results of Operations for a Disposal of a Segment of a Business." FAS 144 is effective for fiscal years beginning after December 15, 2001, with earlier application encouraged. The Company will adopt FAS 144 as of January 1, 2002, and does not expect that the adoption of the Statement will have a significant impact on the Company's consolidated financial position or results of operations.

In August 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 143, "Accounting for Asset Retirement Obligations," which requires that the fair value of a liability for an asset retirement obligation is recorded in the period in which it is incurred and is adjusted to its present value each period. In addition, a corresponding amount must be capitalized by increasing the carrying amount of the related long-lived asset, which is depreciated over the useful life of the related asset. A gain or loss may be incurred upon settlement of the liability. SFAS No. 143 is effective for fiscal years beginning after June 15, 2002. The Company is currently assessing the impact of adopting this statement.

In June 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards No. 141, "Business Combinations," and No. 142, "Goodwill and Other Intangible Assets," effective for fiscal years beginning after December 15, 2001. Under the new rules, goodwill will no longer be amortized but will be subject to annual impairment tests in accordance with the statements. Other intangible assets will continue to be amortized over their useful lives. The pooling of interest method is no longer permitted for business combinations initiated after June 30, 2001.

The Company will apply these new rules beginning in the first quarter of 2002. Application of the non-amortization provisions of the statement on goodwill balances at December 31, 2001, is expected to result in an annual increase in net income of approximately $4.8 million or $0.10 per share. During 2002, the Company will perform the first of the required impairment tests of goodwill as of January 1, 2002, and has not yet determined what the effect of these tests will be on the Company's consolidated financial position or results of operations.

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended, which was required to be adopted in years beginning after June 15, 2000. The Company adopted the new Statement effective January 1, 2001. The Statement required the Company to recognize all derivatives on the balance sheet at fair value. Derivatives that are not afforded special hedge accounting treatment under FAS 133 must be adjusted to fair value through income. If the derivative is afforded special hedge accounting, depending on the nature of the hedge relationship, changes in the fair value of derivatives will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value is immediately recognized in earnings.

Company may change its policies toward the management of certain foreign currency exposures. Any changes that may occur would be to further reduce the Company's exposure to foreign currency risks.

The Company's operations are exposed to market risk from changes in foreign currency exchange rates, interest rates and natural gas prices that could impact its results of operations and financial condition. The Company manages its exposure to these market risks through its regular operations and financing activities and, when deemed appropriate, by using derivative financial instruments in accordance with established policies and procedures. The derivative financial instruments generally used include swaps, forward contracts and options. The derivative financial instruments utilized by the Company in its hedging activities are considered risk management tools and are not used for trading purposes. In addition, derivative financial instruments are entered into with a diversified group of major financial institutions in order to limit the exposure of nonperformance on such instruments.

International operations, including U.S. export sales, constitute a significant portion of revenues and identifiable assets. These operations result in a large volume of foreign currency commitment and transaction exposures and foreign currency net asset exposures. At December 31, 2001 and 2000, the Company's primary net foreign currency market exposures were dispersed through various countries and primarily included the euro and its legacy currencies, the British pound and the Japanese yen. Exposure to variability in currency exchange rates is mitigated, when possible, through the use of natural hedges, whereby purchases and sales in the same foreign currency and with similar maturity dates offset one another. The amount of hedging activity and management of commitment and transaction exposures is coordinated at the corporate level. Hedges are set to mature concurrently with the estimated timing of settlement of the underlying transactions.

Considering the Company's operating profile, at December 31, 2001, the result of a uniform 10% change in the value of the U.S. dollar relative to the currencies in which the Company's sales are denominated would result in a change in operating income of approximately $2.7 million. A similar change in 2000 would have had approximately a $0.2 million effect on operating income. This calculation assumes that each exchange rate would change in the same direction relative to the U.S. dollar, and does not factor in any potential changes in sales levels or local currency prices that may result from changes in exchange rates.

The Company uses commercial paper as a source of financing, which exposes the Company to changes in short-term interest rates. The Company manages its ratio of fixed to floating rate debt with the objective of achieving a mix that management believes is appropriate. To manage this mix in a cost effective manner, the Company, from time to time, enters into interest rate swap agreements in which it agrees to exchange various combinations of fixed and/or variable interest rates based on agreed-upon notional amounts that are supported by the Company's current debt position. At December 31, 2001, the Company had no interest rate swap agreements in effect. Based on the Company's debt position at December 31, 2001, a hypothetical 1 percentage point change in interest rates for a one-year period would change income before income taxes by approximately $1.2 million. This analysis does not consider any effect that a change in interest rates would have on overall economic activity or management actions to mitigate interest rate changes.

As of December 31, 2001, the Company had short-term time investments of $23.9 million representing investment securities with maturities of three months or less. A hypothetical 1 percentage point change in interest rates earned on these deposits for a one-year period would change income before income taxes by $0.2 million.

During the second quarter of 2001, as part of its risk management strategy, the Company entered into fixed price swap and option contracts, including caps and floors, to manage its exposure to changes in natural gas prices. These natural gas contracts obligate the Company to make or receive a payment

equal to the net change in the value of the contracts at their maturity. Such contracts are designated as hedges of the Company's forecasted purchases through 2002 and are effective in hedging the Company's exposure to changes in natural gas prices during this period.

The natural gas contracts that qualify as cash flow hedges under SFAS No. 133 are marked to market with unrealized gains and losses deferred through other comprehensive income (loss) and recognized in earnings when realized as an adjustment to cost of products sold. The fair value of contracts no longer effective as hedges are recognized in cost of products sold from the date that the contracts become ineffective until their expiration. Historically, the Company has not closed any natural gas contracts prior to the execution of the underlying purchase transactions, nor have any of the underlying purchase transactions failed to occur. The fair value of these contracts at December 31, 2001, was immaterial to the Company's consolidated financial position.

Based on the Company's natural gas exposure at December 31, 2001, a hypothetical 10% change in natural gas prices for a one-year period would change income before income taxes by approximately $0.7 million.

The Company is a diversified specialty chemical company. Primary manufacturing operations are located in the United States, Europe and Asia. The Company manages its business and reports segmental information based on the nature of its products and services. The Company's segments include Polymer Additives, Performance Chemicals, Water Treatment and Energy Services and Products. The Company's products are sold globally into the principal markets that include computer and business equipment, consumer electronics, data processing, construction materials, telecommunications, pharmaceuticals and pool and spa dealers and distributors. During 2000 and 2001, the Company sold 46.8% of its ownership in OSCA, Inc. (OSCA), the Company's wholly owned Energy Services and Products subsidiary. OSCA continues to be included in the consolidated financial position and results of operations due to the Company's ability to exert significant influence over OSCA as a result of its continuing ownership and voting interest (see Note 19). Further information on the Company's segments is included in Note 15 to the consolidated financial statements.

The consolidated financial statements include all significant majority-owned subsidiaries of the Company. All material intercompany accounts and transactions are eliminated in consolidation.

Investments in less than majority-owned entities (20% to 50% ownership), in which the Company has the ability to exercise significant influence over operating and financial policies of the investees, are accounted for by the equity method of cost, plus equity, in their undistributed earnings since acquisition. All other investments are carried at their fair values or at cost, as appropriate.

Revenue from sales of products, including amounts billed to customers for shipping and handling costs, is recognized at the time (1) ownership and all risks of loss have been transferred to the buyer, which is generally upon shipment, (2) the price is fixed and determinable and (3) collectibility is reasonably assured. Revenue from services is recognized when the services are provided to the customer.

Shipping and handling costs, including certain warehousing costs, are included in cost of products sold.

Investment securities with maturities of three months or less when purchased are considered to be cash equivalents.

The Company values its inventories at the lower of cost or market. Cost is determined using the first-in, first-out (FIFO) method.

Plant and equipment are stated at cost. Depreciation of buildings and equipment is provided over the estimated useful lives of the assets using the straight-line method. The estimated useful lives for purposes of computing depreciation are: buildings, 10 to 40 years; manufacturing equipment, 7 to 20 years; and office equipment, 3 to 5 years.

Goodwill, the excess of investment over net assets of subsidiaries acquired, is amortized over periods of 8 to 40 years using the straight-line method. As of December 31, 2001 and 2000, accumulated amortization was $31.1 million and $31.0 million, respectively.

When events or circumstances indicate that the carrying amount of long-lived assets to be held and used or intangible assets might not be recoverable, the expected future undiscounted cash flows from the assets is estimated and compared with the carrying amount of the assets. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the assets, an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Fair value is determined based on discounted cash flow or appraised values, as appropriate. Long-lived assets that are held for disposal are reported at the lower of the assets' carrying amount or fair value less costs related to the assets' disposition.

Current income taxes are provided on income reported for financial statement purposes adjusted for transactions that do not enter into the computation of income taxes payable. Deferred income tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Income taxes are provided on the portion of the income of foreign affiliates that is expected to be remitted to the parent company and be taxable. Unremitted earnings of foreign affiliates where income taxes have not been provided are immaterial.

Shares of common stock repurchased under the Company's stock repurchase plans are recorded at cost as treasury stock. When the treasury shares are reissued, the Company uses a weighted average method for determining cost. The difference between the cost of the shares and the reissuance price is included in additional paid-in capital.

Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation," established accounting and disclosure requirements using a fair-value-based method of

accounting for stock-based employee compensation plans. As provided for under SFAS No. 123, the Company accounts for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees." Compensation cost for stock options, if any, is measured as the excess of the quoted market price of the Company's stock at the date of grant over the amount an employee must pay to acquire the stock. Compensation cost for restricted stock awards is recorded over the requisite vesting periods based on the market value on the date of grant.

Assets and liabilities of most foreign subsidiaries are translated at exchange rates in effect at the balance sheet date, and the statements of income are translated at the average monthly exchange rates for the period. Translation gains and losses are recorded as a component of accumulated other comprehensive (loss) income in stockholders' equity until the foreign entity is sold or liquidated. Foreign currency transaction gains and losses are included in net income. Foreign currency translation gains of $6.3 million, $0.2 million and $2.3 million were included in net income in 2001, 2000 and 1999, respectively.

The Company uses various derivative instruments including swaps, forward contracts and options to manage certain foreign currency, interest rate and natural gas price exposures. These instruments are entered into under the Company's corporate financial risk management policy to manage market risk exposures and are not used for trading purposes. Management routinely reviews the effectiveness of the use of derivative instruments.

Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities," requires companies to recognize all of its derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation.

For derivative instruments that are designated and qualify as a fair value hedge (i.e., hedging the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk), the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in the same line item associated with the hedged item in current earnings during the period of the change in fair values. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same line item associated with the forecasted transaction in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in other income (expense)—net in current earnings during the period of change. For derivative instruments that are designated and qualify as a hedge of a net investment in a foreign operation, the gain or loss is reported in other comprehensive income (loss) as part of the cumulative translation adjustment to the extent it is effective. Any ineffective portions of net investment hedges are recognized in other income (expense)—net in current earnings during the period of change. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in other income (expense)—net in current earnings during the period of change.

In October 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," and the accounting and reporting provisions of Accounting Principles Board Opinion No. 30, "Reporting the Results of Operations for a Disposal of a Segment of a Business." SFAS No. 144 is effective for fiscal years beginning after December 15, 2001, with earlier application encouraged. The Company will adopt SFAS No. 144 as of January 1, 2002, and does not expect that the adoption of the Statement will have a significant impact on the Company's consolidated financial position or results of operations.

In August 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 143, "Accounting for Asset Retirement Obligations," which requires that the fair value of a liability for an asset retirement obligation is recorded in the period in which it is incurred and adjusted to its present value each period. In addition, a corresponding amount must be capitalized by increasing the carrying amount of the related long-lived asset, which is depreciated over the useful life of the related asset. A gain or loss may be incurred upon settlement of the liability. SFAS No. 143 is effective for fiscal years beginning after June 15, 2002. The Company is currently assessing the impact of adopting this statement.

The Company will apply these new rules beginning in the first quarter of 2002. Application of the non-amortization provisions of the statement on goodwill balances at December 31, 2001, is expected to result in an annual increase in net income of approximately $4.8 million, or $0.10 per share. During 2002, the Company will perform the first of the required impairment tests of goodwill as of January 1, 2002, and has not yet determined what the effect of these tests will be on the Company's consolidated financial position or results of operation.

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended, which was required to be adopted in years beginning after June 15, 2000. The Company adopted the new Statement effective January 1, 2001. The Statement required the Company to recognize all derivatives on the balance sheet at fair value. Derivatives that are not afforded special hedge accounting treatment under SFAS No. 133 must be adjusted to fair value through income. If the derivative is afforded special hedge accounting, depending on the nature of the hedge relationship, changes in the fair value of derivatives will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value is immediately recognized in earnings.

The effect of the adoption of the Statement was immaterial to the results of operations and other comprehensive income (loss). Because the Statement allows certain foreign currency transactions to be accounted for as hedges for financial reporting purposes that were not previously treated as hedges, the Company may change its policies toward the management of certain foreign currency exposures. Any changes that may occur would be to further reduce the Company's exposure to foreign currency risks.

The special charges related to this repositioning plan totaled $272.1 million, $203.8 million after income taxes, or $4.05 per share, for the year ended December 31, 2001. The special charges consisted of $212.1 million of asset impairments, including $83.3 million for fixed asset impairments and $128.8 million of impaired goodwill, $31.6 million of severance costs, $20.4 million for plant closure and environmental costs and $8.0 million of other costs.

Net special charges for the year ended December 31, 2001, totaled $267.1 million, $200.1 million after income taxes, or $3.98 per share. This reflects the $272.1 million of charges recorded in 2001 offset by a reversal of $3.7 million related to changes in estimates in the 2001 special charge and certain reversals of the special charges taken in 2000 totaling $1.3 million, as detailed below. The net effect of the special charge reversals after income taxes was $3.7 million or $0.07 per share. The net of the 2001 special charges and reversals are reflected in the 2001 consolidated statement of operations as a separate component of operating income.

Details of the 2001 special charges by business unit and a reconciliation to the reserve balance at December 31, 2001, are as follows:

As of December 31, 2001, $47.4 million of the $272.1 million charge remains. The major components of this remaining reserve relate to severance and plant closure costs for the three plant closures and the shutdown of two unprofitable product lines. The majority of the severance costs are expected to be paid out by the end of 2002 and the plant closure and environmental costs by 2005.

The Company recorded a lower of cost or market inventory write-down totaling $43.8 million during 2001. These inventory write-downs include $21.9 million related to the Performance Chemicals business unit, $13.0 million related to Polymer Additives and $8.9 million related to Water Treatment. The Performance Chemicals lower of cost or market inventory write-downs result primarily from market value adjustments to Fine Chemicals inventories related to NSC Technologies. The Polymer Additives portion of the write-down reflects market adjustments resulting from declines in customer demand, and the Water Treatment portion provides for the revaluation of inventory resulting from unsuccessful promotional inventory buys. These write-downs were calculated in accordance with the Company's inventory valuation accounting policies.

Additionally, the Company recorded a $24.5 million liability for environmental remediation costs, $8.7 million for plant shutdown operating inefficiencies, an $8.0 million cumulative U.K. pension liability, $0.9 million of accounts receivable write-offs and $1.0 million of contract cancellation costs. These items amounted to $43.1 million and were recorded in the 2001 consolidated statement of income as follows: $39.8 million to cost of products sold and $3.3 million as a component of selling, general and administrative expenses.

Asset impairment losses in Polymer Additives relate to the planned closure of one underperforming operating site in the U.S. and one in Europe. These charges included the impairment of fixed assets at each site and $18.4 million of impaired goodwill attributable to the sites. In addition, these losses include the impairment of certain nonstrategic bromine and flame retardant production assets at two U.S. operating sites and the impairment of $26.4 million of goodwill related to the 1997 acquisition of an antimony products business. The asset impairment charges for Performance Chemicals include the impairment or disposal of fixed assets relating to the planned closures of a Fine Chemicals production facility in Europe, the sale of a U.S. research and development facility and the shut-down of two unprofitable product lines at a U.S. manufacturing site. Also included in the Performance Chemicals asset charge is $84.0 million of impaired goodwill relating to the acquisition of NSC Technologies in 1999.

These impairment losses adjusted the carrying value of these assets to fair value. Fair value was determined using discounted cash flows. Any impaired fixed assets held for disposal were written down to fair value less costs of disposal. The adjusted carrying value of the assets, classified as held for use, are being depreciated or amortized over the estimated remaining lives of the assets.

Severance costs include the cost of separation payments to certain employees who have been, or will be, terminated. Determinations of the severance costs have either been negotiated individually with the employee; are based upon the provisions of statutory or contractual severance plans; or, in the case of European locations, were negotiated with the employees' respective unions and works councils. The severance charges include severance costs for the termination of approximately 630 positions. At year

end, substantially all personnel subject to the repositioning plan had been given specific notice of termination dates. Notification to European employees was made through the employees' respective unions and works councils. The severance plans include approximately 439 positions for Polymer Additives, 149 positions for Performance Chemicals and 42 positions for Water Treatment and Corporate.

The plant closure and environmental costs associated with the 2001 special charges relate primarily to closure costs such as dismantling, decontamination and remediation, which will be incurred in conjunction with the closure of the three operating sites discussed previously.

The other costs relate primarily to legal and consulting costs associated with the special charge activities, the write-off of certain components of the Company's data processing software proprietary to one of the operating sites being closed, the write-off of certain spare parts inventories associated with the impaired fixed assets and costs resulting from the termination of an equipment lease.

During the second quarter of 2000 the Company announced cost reduction initiatives to further streamline operations, strengthen the Company's competitive position and continue to provide a strong platform for future growth. To accomplish these actions, the Company prepared a formal repositioning plan, which was approved by the Board of Directors on June 23, 2000. The major components of this repositioning plan included the consolidation of the Company's three antimony manufacturing operations, elimination of approximately 375 manufacturing and research and development positions, primarily in the Polymer Additives business unit, and impairment or disposal of certain underperforming and nonstrategic assets. The asset impairments related to four Polymer Additives manufacturing locations, including sites in Europe and the United States, and six Performance Chemicals locations, including sites in the United States, United Kingdom and Germany. The special charges related to this repositioning plan totaled $66.4 million, $49.5 million after income taxes, or $0.95 per share, for 2000. The $66.4 million special charge consisted of $43.8 million for asset impairments, $16.4 million for severance costs and $6.2 million for plant closure and environmental costs. The Company expects to realize approximately $20 million in annual pretax savings as a result of this repositioning. Additional information regarding the 2000 special charges is provided in Note 2 to the consolidated financial statements.

Details of the 2000 special charges by business unit and a reconciliation to the reserve balance at December 31, 2001, are as follows:

Asset impairment losses in Polymer Additives related to the consolidation of the Company's three antimony manufacturing operations and the impairment or disposal of certain underperforming and nonstrategic assets in Europe and the closure of a brine pond operation in El Dorado, Arkansas. The asset impairment charge in Performance Chemicals included the impairment or disposal of underperforming assets at six sites, including three sites in the United Kingdom, two in the United States and one in Germany. These impairment losses adjusted the carrying value of these assets to fair value. Fair value was determined using either discounted cash flow or appraised values, as appropriate. Any impaired assets held for disposal were written down to fair value less costs related to the assets' disposition. The adjusted carrying value of the assets is being depreciated over the remaining lives of the assets.

Severance costs included the cost of separation payments to certain employees who were terminated. These costs were either negotiated individually with the employee or were based upon the provisions of statutory or contractual severance plans. The Company eliminated approximately 375 positions as a result of the 2000 actions. As of December 31, 2001, substantially all personnel subject to the repositioning plan had been terminated. Notification to European employees was made through their respective unions and works councils. The Polymer Additives severance costs related to approximately 300 positions in 13 various locations, including seven locations in the United States; two in Italy; and one each in the United Kingdom, Germany and Switzerland. The Performance Chemicals severance costs included costs to eliminate approximately 60 positions, of which approximately half were in the United Kingdom with the remaining positions being eliminated in Germany and the United States. The Corporate component of the severance costs provided for the elimination of approximately 15 various corporate middle management positions in the United Kingdom, the United States and Switzerland.

The plant closure and environmental costs associated with the 2000 repositioning plan related entirely to the Polymer Additives business unit. These charges included a $4.3 million charge for the closure of a brine pond in El Dorado, Arkansas, and $1.9 million related to dismantling costs incurred as part of the consolidation of the Company's three antimony manufacturing operations.

In the fourth quarter of 1999, the Board of Directors took certain actions to streamline the Polymer Additives business unit, to provide a more flexible data processing solution for the Company's manufacturing operations and to write-down certain assets formerly used in Energy Services and Products' Mexico-based environmental business. The plan was developed to increase the Company's focus on its core specialty chemicals businesses and to position these operations to achieve higher growth and profitability.

Accordingly, the Company recognized a special charge of $25.4 million, $16.5 million after income taxes, or $0.29 per share, during 1999. Offsetting this charge were certain reversals of the special charges taken in 1998 totaling $7.2 million, $4.7 million after income taxes, or $0.08 per share. The net of the 1999 special charges and reversals totaling $18.2 million was reflected in the 1999 consolidated statement of operations as a separate component of operating income.

Details of the 1999 special charges by business unit and a reconciliation to the reserve balance at December 31, 2001, are as follows:

Asset impairment losses in Polymer Additives related to the shutdown of certain unprofitable operating units and the replacement of certain production lines with new technology, primarily in the El Dorado, Arkansas, facility. The asset impairment charge in Energy Services and Products related to a write-down of certain fixed assets formerly used in the Mexico environmental business. Asset impairment losses in Corporate related to the write-off of certain components of the Company's data processing software that had no future use as a result of the Company's decision to provide for more flexibility in its manufacturing systems. The Company recorded an impairment loss to write-down the carrying value of these assets to fair value. Fair value was determined using appraised values. The adjusted carrying value of the assets is being depreciated over the remaining lives of the assets.

Severance costs included the cost of separation payments to approximately 65 employees who were terminated. As of December 31, 2001, all personnel involved had been terminated. In Polymer Additives, the terminations were due to a decision to consolidate research activities in the United States and Europe. Researchers in West Lafayette, Indiana, are now focused primarily on halogen and non-halogen-based flame retardants and performance additives and fluids technology. All European technical service and applications capabilities were consolidated into a new Customer Technical Service and Applications Center in Geel, Belgium. Polymer Additives customers in Europe now receive all the technical service and analytical support they need from a single location, which is located near 80% of the Company's European-based customers. The Corporate severance costs related primarily to information systems personnel. The reversal of $0.4 million in 2001 reflects a change in estimate of the remaining amount of severance costs for the 1999 actions.

During 1997, the Board of Directors approved a plan to exit the furfural and derivatives business, Chemol and environmental services businesses. A portion of the Chemol business was sold during 1998, and essentially all remaining operations were concluded. The environmental services business was sold in January 1999 and the furfural and derivatives business was sold in June 1999. Reserves for the discontinued operations amounted to $3.4 million and $2.2 million at December 31, 2001 and 2000, respectively. Net assets (liabilities) of discontinued operations amounting to $(1.1) million and $1.1 million have been included in other assets on the consolidated balance sheets at December 31, 2001 and 2000, respectively.

On February 14, 2001, the Company finalized its acquisition of an optical monomers business from Akzo Nobel Polymer Chemicals LLC for approximately $30 million in cash, which was funded with available cash and borrowing capacity. As part of the Polymer Additives business unit, the Optical Monomers business operates at a leased manufacturing site in Pasadena, Texas, and has sales and support networks throughout the United States, Europe and Asia. This acquisition was accounted for using the purchase method of accounting with its results of operations included since the date of acquisition. Goodwill resulting from the acquisition amounted to approximately $11.5 million.

On July 14, 2000, the Company finalized its acquisition of Aqua Clear for approximately $40.7 million. Aqua Clear, a manufacturer and distributor of specialty pool chemical products, operated a manufacturing site in Watervliet, New York, which was closed in 2001. Aqua Clear continues to operate distribution sites in St. Louis, Missouri; and Waterford, New York; as well as sales and support networks throughout the United States and Canada. The acquisition of Aqua Clear was accounted for using the purchase method of accounting with its results of operations included since the date of acquisition. Goodwill resulting from the acquisition amounted to approximately $37.8 million.

On August 2, 1999, the Company completed the acquisition of FMC Corporation's Process Additives Division (PAD) for $162 million in cash. PAD is a world leader in the production of phosphate ester flame retardants, flame retardant fluids and lubricant additives, as well as a leading supplier of specialty water treatment chemicals used in industrial applications and desalination. The transaction broadened Great Lakes' Polymer Additives business unit and more than doubled the industrial segment of the Water Treatment business unit. The acquisition was accounted for using the purchase method of accounting with the results of PAD included since the date of acquisition. Goodwill resulting from the acquisition amounted to approximately $62 million.

Effective June 15, 2000, the Company sold 40% of its ownership in OSCA, Inc. (OSCA), the Company's wholly owned Energy Services and Products subsidiary, through an initial public offering.

Net proceeds of approximately $79 million from the initial sale were paid to the Company by OSCA to satisfy indebtedness. The initial sale resulted in a $51.9 million gain to the Company, which was recognized in the second quarter of 2000. Subsequently, on July 13, 2000, the over-allotment option granted to the underwriters was exercised and resulted in an additional $12 million of net proceeds. The over-allotment exercise resulted in an additional gain to the Company of $8.5 million, which was recorded in the third quarter of 2000. The initial sale and the over-allotment option exercise resulted in the Company selling a total of 43.4% of its ownership interest in this subsidiary.

In addition, in each of the first and second quarters of 2001, the Company sold 250,000 shares of OSCA Class B common stock pursuant to Rule 144 under the Securities Act of 1933 for a total of 500,000 shares being sold for the year ended December 31, 2001. The terms of these transactions provided that upon the sale of these Class B shares, the shares were automatically converted to OSCA Class A common stock. Net proceeds were $5.4 million and $6.3 million and the related taxable gains were $4.2 million and $5.2 million for the first and second quarters of 2001, respectively.

The combination of the initial sale, over-allotment option exercise and Rule 144 sales has resulted in the Company selling a total of 46.8% of it ownership interest in this subsidiary. OSCA continues to be included in the consolidated financial position and results of operations due to the Company's ability to exert significant influence over OSCA as a result of its continuing ownership and voting interest (see Note 19).

On July 15, 1999, the Company sold $400 million of 7% notes due July 15, 2009. Proceeds from the sale of the notes were used to replace a portion of the commercial paper borrowings. The notes were sold under a shelf registration process. Under this process, the Company filed a Registration Statement on Form S-3 with the Securities and Exchange Commission and may sell various unsecured debt securities, common stock or rights or warrants to purchase common stock individually or in combination up to $750 million. The amount remaining on the registration statement is $350 million.

On October 4, 2001, the Company established two unsecured revolving credit facilities with various financial institutions under which it may borrow up to $237.5 million under each facility for a total of up to $475.0 million. One facility has a 364-day term and the other facility has a five-year term. Both are used to support the commercial paper program and for general corporate purposes. The 364-day agreement may be renewed annually, subject to certain conditions. Both facilities contain covenants, which include requirements for a ratio of debt to EBITDA, ranging from 3.5 to 1 in 2001 to a maximum of 5.15 to 1 for the first three quarters of 2002, as defined in the agreements. These facilities replaced the $600.0 million revolving credit facility that expired on October 4, 2001.

The weighted average rate of interest on commercial paper borrowing was 3.9% at December 31, 2001. The interest rate on industrial development bonds was 1.8% at December 31, 2001, and the bonds have maturities through 2025.

Commercial paper financing has been classified as a component of long-term debt since the Company intends to refinance these borrowings on a long-term basis either through continued commercial paper borrowings or utilization of available long-term credit facilities.

Long-term debt matures as follows: 2002, $11.2 million; 2003, $31.0 million; 2004, $2.9 million; 2005, $2.7 million; 2006, $1.5 million; and thereafter, $489.7 million.

During 2001, 2000 and 1999, interest costs were $43.9 million, $53.8 million and $35.1 million, respectively, which included interest capitalized as additional costs of plant and equipment of $1.0 million in 2001, $1.7 million in 2000 and $3.5 million in 1999. In these years, cash interest payments were $44.1 million, $54.2 million and $22.2 million, respectively.

The following is a summary of domestic and foreign income before income taxes, the components of the provisions for income taxes, a reconciliation of the United States federal income tax rate to the effective income tax rate and the components of deferred tax assets and liabilities.

The 2001 effective income tax rate is lower than the Company's expected ongoing effective income tax rate of 31% due primarily to the significant increase in the valuation allowance and the recognition of approximately $14.7 million of tax expense related to the change in strategy regarding the disposition of OSCA (see Note 19).

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

As of December 31, 2001, the Company had tax credit carryforwards of $29.1 million available. A valuation allowance of $12.9 million has been recorded against the portion of these credit carryforwards

for which utilization is uncertain. Of the amount of tax credit carryforwards for which no valuation allowance has been recorded, $0.7 million expire in 2018; $2.6 million expire in 2019; $3.2 million expire in 2020; $3.3 million expire in 2021; and the remaining $6.4 million have no expiration dates. At December 31, 2001, the Company and certain of its foreign subsidiaries had net operating losses totaling $329.0 million. These carryforwards will be available to offset $119.9 million of future tax liabilities. A valuation allowance of $36.5 million has been recorded against the portion of these net operating loss carryforwards for which utilization is uncertain. Of the amount of net operating loss carryforwards for which no valuation allowance has been recorded, $70.6 million expire in 2021 and the remaining $12.8 million have no expiration dates.

Cash payments for income taxes were $14.3 million, $11.2 million and $24.0 million in 2001, 2000 and 1999, respectively.

The Board of Directors has authorized the Company to purchase shares of the Company's common stock in the open market or in privately negotiated transactions. Pursuant to these authorizations, the Company purchased approximately 0.1 million shares during 2001 at an average price of $22.19 per share. A total of 2.8 million shares remain available under existing authorizations by the Board of Directors.

Under a Stockholders Rights Plan adopted in 1999, for each outstanding share of common stock of the Company held by a stockholder, each stockholder had a right, which entitled the holder upon certain triggering events described in the Stockholder Rights Plan, to acquire at the right's then current exercise price, the number of shares of common stock of the Company (or, if applicable, an acquiring company) having a market value equal to twice the right's exercise price.

On February 12, 2002, the Company's Board of Directors redeemed the outstanding rights under the Stockholders Rights Plan at a price of $.01 per right, payable to stockholders of record on April 1, 2002.

Basic earnings per share is based on the weighted average number of common shares outstanding during the period, while diluted earnings per share includes the effect of options and restricted stock that were dilutive and outstanding during the period. The computation of basic and diluted earnings per share is determined using net income or loss as reported as the numerator, and the number of shares included in the denominator is calculated as follows:

Options to purchase shares of common stock of 3.3 million in 2001, 3.1 million in 2000 and 1.6 million in 1999 were outstanding, but were excluded from the computation of diluted earnings per share because the exercise prices were greater than the average market price of the common shares during those years and, therefore, the effect would have been antidilutive.

The Company has three plans that provide for the granting of stock awards to officers and key employees. The 1998 and the 1993 Stock Compensation Plans have stock awards available for grant; the third plan, which has no stock awards available for grant does have options exercisable as of December 31, 2001. The Company is authorized to grant options for up to 4.5 million shares under the plans, of which 2.8 million have been granted. Options under the plans have been granted at the market value at the date of grant, become exercisable over periods of one to five years and expire 10 years from the date of grant.

In addition to the options awarded under the plans, the Company on April 6, 1998, granted the chief executive officer an option to acquire 0.7 million shares of the Company's stock. The options were granted at market value on the date of grant; 0.2 million of the shares became exercisable upon grant with the remaining shares becoming exercisable ratably over four years. The options expire 10 years from the grant date.

During 2001, 2000 and 1999, the Company awarded restricted stock totaling 0.09 million, 0.014 million and 0.1 million shares, respectively, to directors and key employees. These awards become exercisable over a period of 1 to 10 years. The Company recognizes compensation expense consistent with the vesting of each award. The compensation expense incurred in 2001, 2000 and 1999 related to these awards totaled $0.7 million, $1.0 million and $1.3 million, respectively.

The following table summarizes information concerning outstanding and exercisable options at December 31, 2001:

The Company accounts for stock compensation costs in accordance with the provisions of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. Accordingly, no compensation cost has been recognized for its fixed stock option plans. The following table sets forth pro forma information as if compensation cost had been determined based on the fair value at the grant date for awards under the Company's stock plans consistent with the requirements of SFAS No. 123, "Accounting for Stock-Based Compensation." For the purposes of the pro forma disclosure, the estimated compensation costs are amortized to expense over the options' vesting period, principally three years.

The Company sponsors various defined benefit pension plans. The following table provides a progression of the plans' benefit obligations and fair value of plan assets and reconciles the funded status to the amounts recognized in the balance sheets for 2001 and 2000, respectively.

Amounts applicable to the Company's pension plans with accumulated benefit obligations in excess of plan assets are as follows:

The Company provides no significant postretirement benefits other than pensions.

Certain Company employees participate in the Great Lakes Savings Plan, which is a defined contribution, 401(k) employee savings plan generally available to all U.S. full-time salaried, nonunion hourly employees and certain union hourly employees. The plan is funded by contributions from participants and the Company. Contributions by the Company to the plan were approximately $2.9 million, $3.4 million and $4.2 million in 2001, 2000 and 1999, respectively.

The Company also maintains a supplemental savings plan, the Great Lakes Chemical Corporation Supplemental Savings Plan. The plan is nonqualified and restores the employer match that certain employees lose due to IRS limits on eligible compensation under the Great Lakes Savings Plan. Contributions by the Company to this plan were approximately $0.1 million, $0.1 million and $0.1 million in 2001, 2000 and 1999, respectively.

Research and development expenses were approximately $40.7 million, $39.5 million and $45.7 million in 2001, 2000 and 1999, respectively.

The Company is organized in the four global segments: Polymer Additives, Performance Chemicals, Water Treatment and Energy Services and Products. These segments are strategic business units that offer products and services that are intended to satisfy specific customer requirements. The units are organized and managed to deliver a distinct group of products, technology and services.

The Polymer Additives segment produces bromine-, phosphorus- and antimony-based flame retardants; antioxidants; UV absorbers; light stabilizers; optical monomers and patented No Dust Blends (NDB™). The segment serves suppliers in a wide variety of industries, including electrical and electronic, construction, automotive and furnishings.

The Performance Chemicals segment produces chemicals to exact specifications or to meet specific applications requirements. The product offering is characterized by technology-based product solutions that benefit specific customers. The businesses included in the segment are: agricultural products; brominate intermediates; fluorine chemicals for use in fire suppression systems, refrigerants and medical and pharmaceutical products; fine chemicals for pharmaceuticals and life sciences companies; and toxicological testing services, pharmaceuticals, chemicals and biotechnology customers.

The Water Treatment segment is a producer of water treatment chemicals for the recreational and commercial swimming pool and spa water treatment industry. These products are sold to pool and spa dealers, distributors and mass market retailers. The Water Treatment segment also produces specialty biocides, antiscalants, corrosion inhibitors and other products for use in cooling tower water treatment; wastewater treatment; pulp and paper processing; and desalination products.

The Energy Services and Products segment provides specialized oil and gas well completion fluids, completion services and downhole completion tools to major oil and gas companies and independent exploration and production companies, primarily in the Gulf of Mexico and select international markets.

The Company evaluates business unit performance and allocates resources based on the operating income, which represents net sales less cost of products sold and selling, general and administrative expenses, and cash flows of each business unit. Each of the Company's segments uses bromine as a raw material in their production processes. Bromine is transferred at cost to all business segments, except Energy Services and Products. Their cost is based upon a bromine supply agreement. In addition, assets used in the production of bromine are allocated to each business unit, with the exception of Energy Services and Products, based on the percentage of production consumed. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies.

Corporate includes the corporate offices and any other activities not associated with a specific segment. Segment assets include primarily accounts receivable, inventory, net plant and equipment and other miscellaneous assets. Assets included in Corporate principally are cash and cash equivalents; insurance receivables; deferred income taxes; certain investments and other assets; and certain unallocated plant and equipment, including the Company's enterprise resource planning (ERP) software systems. Geographic sales information is reported based on the location that invoices the

external customer. Geographic long-lived assets are grouped by the location of the reporting country. Intersegment sales are insignificant and are eliminated in consolidation.

As of December 31, 2001, the Company's investment in unconsolidated affiliates consists of a 49% interest in Gulf Stabilizers Industries Limited, a Saudi Arabian manufacturer of antioxidants, and a 50% interest in Tetrabrom Technologies, Ltd., an Israeli manufacturer of tetrabromobisphenol-A. During 1999 and 2000, the Company sold its remaining preferred stock in Huntsman Chemical Company (HCC). The Company had recognized pretax gains on sales of HCC preferred shares of $3 million and $9 million in 2000 and 1999, respectively. Preferred stock dividends from HCC amounted to $0.3 million and $7 million in 2000 and 1999, respectively. The Company is also a limited partner in certain low income housing investments that generate benefits in the form of tax credits.

The Company's equity in earnings of unconsolidated affiliates was $0.7 million, $5.7 million and $1.0 million in 2001, 2000 and 1999, respectively.

In the normal course of business, operations of the Company are subject to risks associated with changing foreign exchange rates. These fluctuations can vary the costs of financing, investing and operating activities. Accordingly, the Company hedges certain portions of its exposure to foreign currency fluctuations through the use of options and forward exchange contracts to protect the value of its existing foreign currency asset and liability commitments and anticipated foreign currency revenues.

It is the Company's policy to enter into foreign currency hedging transactions only to the extent considered necessary to achieve the objectives stated above. The Company does not enter into foreign currency transactions for trading purposes.

The Company enters into currency option and forward contracts to hedge anticipated foreign currency transactions during the next 12 months. The principal currencies hedged are the Japanese yen, the British pound and the euro.

The Company uses foreign currency swap contracts to hedge a long-term intercompany loan. These contracts hedge the Italian lira against the British pound. The terms of the swap contracts match the loan principal repayment terms. Gains or losses on these contracts are reflected in earnings and are offset by losses or gains on the underlying intercompany loan.

Gains and losses arising from the use of the above instruments are recorded in the income statement. The impact of currency forwards and options used for foreign exchange risk management on pretax income in 2001, 2000 and 1999 was a net (loss) gain of approximately $9.2 million, $(1.6) million and $(0.7) million, respectively.

The Company utilizes a number of methods to provide both long-term and short-term financing for its operations. The Company has historically relied on a floating rate commercial paper program for ongoing working capital and, more recently, issued $400 million of 7% fixed rate notes due July 15, 2009.

The Company has employed certain hedging instruments to minimize its exposure to changes in interest rates, including an interest rate swap agreement. In 2000, the Company terminated its swap arrangement and as a result recognized a $2.9 million gain, which is being amortized over the remaining term of the underlying 7% fixed rate notes that are due July 15, 2009. The Company has also utilized other interest rate derivative instruments to manage its exposure to interest rate changes; however, there were no positions outstanding at either December 31, 2001 or 2000 related to these activities.

The impact on pretax income of interest rate risk management activities was a net gain of approximately $0.4 million and $4.0 million for 2000 and 1999, respectively. There was no impact on pretax income related to 2001.

The Company consumes natural gas during the normal course of production. The fluctuations of natural gas prices can vary the costs of production. During the second quarter of 2001, as part of its risk management strategy, the Company entered into fixed price swap and option contracts, including caps and floors, to manage its exposure to changes in natural gas prices. These natural gas contracts obligate the Company to make or receive a payment equal to the net change in the value of the contracts at their maturity. Such contracts are designated as hedges of the company's forecasted natural gas purchases up to the end of year 2002 and are effective in hedging the Company's exposure to changes in natural gas prices during this period.

The natural gas contracts that qualify as cash flow hedges under SFAS No. 133 are marked to market with unrealized gains and losses recorded in other comprehensive income and recognized in earnings when realized as an adjustment to cost of products sold. The fair value of contracts no longer effective as hedges are recognized in cost of products sold from the date that the contracts become ineffective until their expiration. Historically, the Company has not closed any natural gas contracts prior to the execution of the underlying purchase transactions, nor have any of the underlying purchase transactions failed to occur. The impact on pretax income of natural gas risk management activities was a net (loss) gain of approximately $(1.8) million for 2001. This includes the amounts recognized for derivative instruments that do not qualify as cash flow hedges under SFAS 133. During the year ended

December 31, 2001, the Company did not recognize any gain or loss in earnings related to the ineffectiveness of its hedging instruments.

As of December 31, 2001, the Company expects to reclassify $1.3 million of net losses on derivative instruments from accumulated other comprehensive income to earnings during the next twelve months due to actual purchases of natural gas.

For certain of the Company's financial instruments, including cash and cash equivalents, accounts and notes receivable, accounts payable and accrued expenses, the stated values approximate fair value due to their short-term nature. Consequently, such financial instruments are not included in the following table that provides information about the stated values and estimated fair values of other financial instruments, both on and off the balance sheets:

The estimated fair value of long-term debt is based primarily on quoted market prices for the same or similar issues. The fair values of option, forward exchange and swap contracts are based on quoted market prices of comparable instruments.

The Company sells a broad range of products to a diverse group of customers operating throughout the world. These industries generally are not significantly affected by changes in economic or other factors. Credit limits, ongoing credit evaluation and account monitoring procedures are utilized to minimize the risk of loss. Collateral is generally not required. Counter-parties to the currency swap agreements are major financial institutions. Credit losses from counter-party nonperformance are not anticipated.

The Company has various purchase commitments for raw materials, supplies and plant and equipment incident to the ordinary conduct of business. None of the raw material and supply commitments represents an unconditional purchase obligation. In the aggregate, such commitments are not at prices in excess of current market. At December 31, 2001, the Company had committed approximately $61 million to complete capital projects.

At December 31, 2001, the Company had guaranteed $19.1 million of debt of an unconsolidated affiliate.

The Company has various operating leases primarily for the use of office space, computer equipment and services and marine service vessels. Future minimum lease payments under these noncancelable operating leases totaled $57.8 million at December 31, 2001, due as follows: 2002—$16.6 million; 2003—$9.2 million; 2004—$6.9 million; 2005—$6.0 million; 2006—$5.7 million; 2007 and thereafter $13.4 million.

Rent expense for all operating leases amounted to $31.6 million, $27.5 million and $25.2 million for 2001, 2000 and 1999, respectively.

The Company is subject to various lawsuits and claims with respect to matters such as governmental regulations, income taxes and other actions arising out of the normal course of business. The Company is also subject to contingencies pursuant to environmental laws and regulations that in the future may require the Company to take action to correct the effects on the environment of prior manufacturing and waste disposal practices.

On September 18, 2000, OSCA, the Company's Energy Services and Products subsidiary, was served with notice that a lawsuit was filed against it and other named defendants on September 1, 2000 in the District Court of Harris County, Texas. The action is brought by certain underwriting syndicates of Lloyd's of London who claim to be subrogated to the claim of their insureds, Newfield Exploration Company, Apache Oil Corporation, Continental Land & Fur and Fidelity Oil ("Plaintiffs"). The other defendants include High Pressure Integrity, Inc. and Chalmers, Collins & Alwell, Inc. On September 8, 2000, OSCA filed a lawsuit against the Plaintiffs and the other defendants in the United States District Court, Western District of Louisiana, Lafayette-Opelousas Division. Other actions have also been filed in connection with the same circumstances. All actions have now been consolidated into one proceeding in the United States District Court, Southern District of Texas.

OSCA has denied that it breached its contract or was negligent and intends to vigorously defend itself and to prosecute the merits of its claims. Mediation has been set in the combined lawsuits for March 5, 2002, and a trial date of March 14, 2002, has been set. On February 22, 2002, the court issued preliminary rulings in the case, one of which was partial summary judgment in favor of Newfield and against OSCA on the issue of breach of contract and another ruling was a dismissal of OSCA's claims against Cardinal Wireline Service. The court specifically stated, and OSCA believes, that this ruling is not dispositive as to whether OSCA's actions caused the blowout and therefore is liable for damages to Newfield. Management is unable to predict whether the outcome of this legal action will have a material adverse effect on the results of operations in any particular period. However, management does not believe that the outcome will have a material adverse effect on the Company's consolidated financial position or liquidity (see Note 19).

West Lafayette Corporation, a wholly owned subsidiary of the Company, is a defendant in a judicial proceeding filed on August 30, 2000, by the State of Illinois in the Circuit Court of Illinois. The State is seeking penalties based on alleged failure to maintain air emission permits required by the State of Illinois and federal law. The Company is currently investigating the issue and has neither agreed to nor denied the allegations. However, Company's management believes that the liability, if any, associated with such allegations will not have a material adverse effect on the Company.

In April 1999, the Company reached agreement with the National Labor Relations Board to settle a 1986 lawsuit alleging unfair labor practices at the Company's Newport, Tennessee, facility following its acquisition of the site from Syntex Corporation. The $9 million settlement covers back pay and interest for certain former Syntex employees. The settlement amount is consistent with previously established reserves.

Litigation accruals of approximately $13.3 million and $3.3 million have been reflected in the Company's consolidated balance sheet as of December 31, 2001 and 2000, respectively.

responsibility for remediation of hazardous substances and hazardous waste constituents released into the environment.

The Company provides reserves for environmental liabilities that management considers probable for which a reasonable estimate of the liability can be made. Accordingly, the Company's reserves for environmental liabilities, including reserves associated with restructuring charges, were approximately $59.1 million and $17.4 million at December 31, 2001 and 2000, respectively. While it is difficult to predict or determine the outcome of actions brought against the Company or the ultimate cost of environmental matters, management believes that the ultimate cost, if any, in excess of the amounts already provided is not likely to have a material adverse effect on its consolidated financial position, consolidated results of operations or liquidity.

On February 20, 2002, the Company announced that OSCA entered into a definitive merger agreement with BJ Services Company. Under the terms of the agreement, BJ Services will acquire all of the outstanding shares of OSCA, including the Company's 53.2% holding, for $28.00 per share in cash.

The Company and BJ Services also entered into an indemnification agreement at the time of signing the merger agreement. Pursuant to this agreement, the Company has agreed to pay BJ Services a certain percentage of all amounts of uninsured cash damages, if any, in excess of a certain amount paid by OSCA resulting from a settlement or final determination of certain pending litigation against OSCA (see Note 18).

There can be no assurances that the merger will be consummated in accordance with the terms of the merger agreement, if at all.

A summary of the quarterly results of operations for the years ended December 31, 2001 and 2000 follows:

The financial statements are prepared in accordance with accounting principles generally accepted in the United States and include amounts that are based on management's informed judgments and estimates.

An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Great Lakes Chemical Corporation and subsidiaries at December 31, 2001 and 2000, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States.
