EXPLANATORY NOTE

     This Amendment No. 2 to the Annual Report on Form 10-K of Hercules Incorporated (the “Company”) for the year ended December 31, 2003 is being filed to restate its Balance Sheets, Statements of Stockholders’ Equity and related notes to the Consolidated Financial Statements for income tax adjustments resulting from a review of the Company’s GAAP accounting for income taxes for the tax years 1987 through 1995. The adjustments reflected in this Form 10-K/A relate to the computation and application of foreign tax credits and reduce the tax deposit asset by $65 million, increase deferred income tax assets by $17 million, and, as a result of the cumulative additional income tax expense to be recorded for the restated periods, reduce retained earnings and stockholders’ equity by $48 million as of January 1, 1996 and for previously reported periods affected through December 31, 2003. The restatement does not affect the previously reported results of operations for any period subsequent to December 31, 1995. The restatement, which was previously disclosed in a Form 8-K issued on November 9, 2004, is more fully described in Note 26 to the Consolidated Financial Statements.

     In addition, the Company has changed the classification of the incentive stock plan activity in the Consolidated Statement of Stockholders’ Equity from a net to a gross basis. This change in classification resulted in a net decrease of $7 million from Other assets and Unearned compensation included in Stockholders’ equity.

     This Form 10-K/A includes amendments to the following items and exhibits as a result of the restatement:

     The following discussion should be read in connection with the information contained in the Consolidated Financial Statements and Notes thereto. All references to individual Notes refer to Notes to the Consolidated Financial Statements. As referenced in Note 26 to the Consolidated Financial Statements, the Consolidated Balance Sheets, Statements of Stockholders’ Equity and related Notes to Consolidated Financial Statements have been restated in connection with adjustments recorded as of January 1, 1996.

Overview

     Hercules is a leading global manufacturer and marketer of specialty chemicals and related services for a broad range of business, consumer and industrial applications with net sales of $1,846 million, $1,705 million and $1,776 million, respectively, in 2003, 2002 and 2001. The Company’s principal products are chemicals used by the paper industry to increase product performance and enhance the manufacturing process; water-soluble polymers; polypropylene and polyethylene fibers; and specialty resins. Key markets for the Company’s products, as a percent of 2003 net sales, include: Pulp and Paper – 49%; Paints and Adhesives – 10%; Construction Materials – 9%; Food, Pharmaceutical and Personal Care — 20%; and Industrial Specialties including Oilfield, Textiles and General Industrial – 12%. Over 50% of the Company’s revenues are generated outside of North America. Net sales by region in 2003 were: North America – 48%, Europe – 38%, Asia Pacific – 9% and Latin America – 5%. The Company operates through two reportable segments and four divisions: Performance Products (Pulp and Paper and Aqualon) and Engineered Materials and Additives (FiberVisions and Pinova). Net sales for 2003 as a percent of total sales, by division, were: Pulp and Paper — 47%; Aqualon — 33%; FiberVisions - 15%; and Pinova — 5%.

     Pulp and Paper is a large and technically advanced provider of pulp and paper chemicals and technical paper process solutions. The industry in which Pulp and Paper competes is projected to experience average growth rates of 2% to 3% through 2004. Demand for process chemicals, retention aids and strength resins has increased as the quality of pulp used in paper products has been reduced. However, the industry has become increasingly competitive as consolidation continues within the pulp and paper customer base. Aqualon is a supplier of products that manage the properties of aqueous (water-based) systems. Aqualon’s products are mostly derived from renewable natural raw materials, including cellulose and guar, and are used in paints and coatings, personal care products such as toothpaste and shampoo, oil and gas well drilling to provide fluid loss control and as a strengthening agent in mortar and plaster, among other uses.

     FiberVisions is a global supplier of synthetic fibers made from polypropylene and polyethylene used primarily in non-woven fabrics for disposable diapers and other hygienic products. Pinova offers products that generally are custom made to fit a particular use in an industry and impart or improve the properties of a variety of compounded substances.

     Performance in 2003 was impacted by several significant economic factors: higher costs, especially for energy and energy-related raw materials, but also for pension benefits; overall flat price-volume-mix growth; 20% appreciation in the Euro against the U.S. dollar; and continued productivity improvement offsetting the negative effects of the higher costs. In addition, Pulp and Paper, Aqualon and FiberVisions benefited from new product introductions.

     Higher cost energy and natural gas/crude oil (as feedstock) are impacting many raw materials, particularly derivatives of chlor-alkalai, ethylene, benzene, propylene and natural gas. The Company has instituted a number of initiatives to mitigate these negative effects, including product substitution, exploring new sourcing opportunities and entering into forward contracts for a portion of its natural gas requirements.

     Paper and paperboard production was down 2% in North America. Office paper production in Europe, a key market for Hercules, was also down 2%. Factors impacting the North American paper industry include a declining manufacturing base as more production shifts off-shore to countries such as China, lower classified advertising (newsprint), lower weight magazines and a slowdown in print advertising, and plastics substitutes for liquid packaging.

     Market conditions affecting the Aqualon business were generally stable in 2003. Volume growth was fueled by an increase in the construction, oil field and personal care businesses. Global price increases were implemented in the first half of 2003, partially offsetting higher raw material and energy costs. Further price increases have been announced to offset new raw material increases.

     In FiberVisions, margins were under pressure in Europe (including the Middle East and Africa), the Americas and Asia due to renewed competitive activity and higher raw material prices. The business mitigated these factors through continued streamlining of its fixed cost structure. New product introductions and the consolidation of the ES FiberVisions joint ventures contributed $33 million and $29 million, respectively, to net sales growth in 2003.

     Lower volumes in the Pinova business were driven by lost business in its chewing gum and adhesives markets. Higher raw material costs and pension expense also negatively impacted profits. The business has been successful in regaining most of the lost volumes through increased sales to existing customers and the addition of new customers.

     In addition to the above economic factors, performance in 2003 was influenced by a number of discrete items, as discussed below.

     Effective January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 143, “Accounting for Asset Retirement Obligations” (“SFAS 143”). SFAS 143 requires that the fair value of an asset retirement obligation be recorded when incurred. Included within the scope of SFAS 143 are environmental remediation liabilities associated with current and former operations that were incurred during the course of normal operations. As more fully discussed in Note 12 to the Consolidated Financial Statements, concurrent with the adoption of SFAS 143, the Company recorded an after-tax charge of $28 million ($44 million on a pre-tax basis), or $0.26 per share, as a cumulative effect of a change in accounting principle.

     Also effective January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”), as amended by Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation – Transition and Disclosure” (“SFAS 148”). The Company has elected to apply the fair value recognition provisions of SFAS 123 on a prospective basis to all employee awards granted, modified or settled after January 1, 2003. The Company did not grant any stock options pursuant to SFAS 123, as amended by SFAS 148, to employees in 2003. Restricted stock awards under the Hercules Long-term Incentive Compensation Plan are valued at the quoted market price (fair value) of the Company’s stock on the grant date (measurement date). The Company recognized $4.3 million, $0.5 million and $1.7 million of expense in 2003, 2002 and 2001, respectively, in connection with restricted stock awards (see Summary of Significant Accounting Policies).

     In August 2003, the Company’s Board of Directors granted a special pension benefit recognizing past service to Dr. William H. Joyce, the then Chief Executive Officer of the Company. The special pension benefit, which fully vested on the grant date for the services rendered through that date, has been accounted for as deferred compensation in accordance with APB No. 12, Omnibus Opinion, as amended by SFAS No. 106, Employers’ Accounting for Postretirement Benefits Other Than Pensions. The special pension benefit has an estimated net present value of approximately $4.7 million. Any award of incentive compensation to Dr. Joyce for 2003 will result in an increase in this amount as a result of the application of the standard pension formula.

     Subsequently, on October 6, 2003, Dr. Joyce resigned from the Company and its Board of Directors to accept another executive position in the industry. The Board elected outside director John K. Wulff as Non-Executive Chairman of the Board and also named Craig A. Rogerson acting President and Chief Operating Officer. On December 11, 2003, the Board elected Mr. Rogerson President and Chief Executive Officer and a member of the Board of Directors. In addition to these new duties, Mr. Rogerson has remained President of Hercules’ FiberVisions and Pinova divisions and Corporate Vice President of Global Procurement, positions he assumed in April 2002. John K. Wulff continues as Non-Executive Chairman of the Board.

     Effective September 30, 2003, the Company elected to partially adopt FASB Interpretation No. 46, “Consolidation of Variable Interest Entities” (“FIN 46”), for its variable interest entities (“VIEs”) that existed prior to January 31, 2003 (the Company has no VIEs created subsequent to January 31, 2003). The consolidation of ES FiberVisions Holding A/S and ES FiberVisions L.P. increased 2003 net sales by approximately $29 million and profit from operations by $3 million (see Note 7).

     The Board of Directors has authorized the Company, from time to time, subject to market conditions and provisions of the Company’s credit agreement, to repurchase up to $140 million of its outstanding indebtedness. Pursuant to the Term B Loan Credit Agreement, and subject to related covenants, the Company has the right to use available cash to repurchase, repay or otherwise redeem up to $100 million of the 11 1/8% senior notes and $40 million of the company-obligated trust preferred securities (“Preferred Securities”) in any fiscal year. During the fourth quarter ended December 31, 2003, the Company repurchased $24 million (book value) of its 11 1/8% senior notes for $29 million, recognizing a loss of $5 million, and 46,000 of its CRESTS Units for a total of $34 million, of which $27 million was attributed to the preferred security component and $7 million was attributed to the warrants.

     On December 1, 2003, the Company completed the acquisition of Quantum Hi-Tech Co. Ltd., (“Quantum”). Quantum is a leading producer of carboxymethylcellulose products in China. Quantum has current production capacity of 6,000 MT (metric tons); its leading key markets include food, toothpaste, ceramics and paper, with annual sales of approximately $10 million (see Note 25).

     On December 17, 2003 the Company amended its senior credit facility to, among other things, lower the term B loan interest rate to LIBOR + 2.50% from LIBOR + 3.25% (see Note 6).

     Fourth quarter 2003 net income includes a $6 million pre-tax charge, net of insurance, to increase the Company’s reserve for future asbestos costs following the conclusion of a study commissioned in early 2003. Based on the results of the study, the Company estimates that its reasonably possible gross financial exposure for asbestos-related matters will range from $220 million to $675 million. The Company recorded a gross charge of $55 million as of December 31, 2003, thereby increasing its recorded liability for future asbestos costs, before anticipated insurance recoveries, to $221 million, reflecting the low end of the range noted above and $1 million for previously settled but unpaid asbestos cases. The Company believes that it is probable that at least $169 million of the recorded liability will be paid or reimbursed by its

5

insurance carriers. Accordingly, an increase of $49 million to the associated receivable for anticipated insurance recoveries was recorded as of December 31, 2003 (see Note 13).

     As set forth in Note 1 to the Consolidated Financial Statements, in the fourth quarter ending December 31, 2003, the Company changed its method of accounting for its Employee Stock Ownership Plan (“ESOP”). The effect of the change was to increase net income by $5 million and earnings per share by $0.05 in both 2002 and 2001, as well as to increase net income by $2 million, $1 million and $1 million and earnings per share by $0.02, $0.01 and $0.01 in the quarters ended March 31, 2003, June 30, 2003 and September 30, 2003, respectively. In addition, retained earnings at January 1, 2001 was increased by $5 million, net of taxes, unearned compensation has been increased by $2 million and additional paid-in-capital decreased by $7 million for the retroactive effect of this change in accounting.

     On February 12, 2004, the Company completed the sale of its minority ownership in CP Kelco ApS for $27 million in cash. On March 1, 2004, the Company announced that the proposed acquisition of Meraklon S.p.A. will not occur, as a result of difficulties encountered in obtaining antitrust regulatory approval.

     The Company implemented Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”) effective January 1, 2002. Under the provisions of this standard, goodwill and intangible assets with indefinite useful lives are not amortized but instead are reviewed for impairment at least annually and written down only in periods in which it is determined that the fair value is less than the recorded value. In connection with the Company’s transitional review, recorded goodwill was determined to be impaired in the BetzDearborn and FiberVisions reporting units. The Company recognized after-tax impairment charges of $262 million in the BetzDearborn reporting unit and $87 million in the FiberVisions reporting unit. In addition, an after-tax impairment charge of $19 million was recognized for the Company’s equity investment in CP Kelco (see Note 4) in the first quarter of 2002.

     On April 29, 2002, Hercules completed the sale of the Water Treatment Business to GE Specialty Materials (“GESM”), a unit of General Electric Company for $1.8 billion. The Company used the net proceeds to prepay debt under its senior credit facility and ESOP credit facility (see Notes 6 and 10). Pursuant to Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS 144”), the BetzDearborn Water Treatment Business has been treated as a discontinued operation as of February 12, 2002, and accordingly, all financial information has been restated. The loss from discontinued operations for the year ended December 31, 2002 includes an after-tax loss on the disposal of the business of $230 million. The BetzDearborn Water Treatment Business had net assets, including goodwill and identifiable intangibles from the BetzDearborn acquisition, of approximately $2.0 billion at December 31, 2001. Approximately 3,900 employees transferred to GESM or left the Company in connection with the sale. Hercules has an agreement with GESM to distribute water treatment products to the pulp and paper industry (see Note 25).

     In June 2001, the Company announced an aggressive and comprehensive program to improve return on capital and cash flow, streamline organizational structure, improve work processes, consolidate manufacturing and non-manufacturing resources and better serve customers. The initial objective was to achieve fixed cost reductions of $100 million on an annualized basis (as compared to 2000 results, excluding the Food Gums business and the Resins divestitures) by June 2002, which was achieved by December 31, 2001. In the beginning of 2002, the cost reduction target was increased to $200 million in annualized fixed cost reductions to be achieved by December 2002 (as compared to 2000 results, excluding the Food Gums business and the Resins divestitures), including $75 million for the Water Treatment Business and $125 million for the other remaining businesses. Subsequent to the sale of the Water Treatment Business, the Company raised the cost reduction target to be achieved by December 2002 for the remaining businesses to $150 million in annualized fixed cost reductions (as compared to 2000 results, excluding the Food Gums business, the Resins divestitures and the Water Treatment Business). At the end of 2002, the Company achieved approximately $160 million in annualized cost reductions, exceeding the Company’s twice upwardly revised cost reduction target. Approximately 1,340 employees have left or will leave the Company under this plan. The Company incurred restructuring charges totaling $51 million during the third and fourth quarters of 2001. Pursuant to the cost reduction and work process redesign program initiated in 2001 (see Notes 18 and 19), the Company incurred restructuring charges totaling $25 million during 2002. The plan includes reductions throughout the Company with the majority of them from support functions.

     The above-mentioned items are primarily included in corporate in each of the respective years in the segment footnote disclosure (see Note 23).

Critical Accounting Estimates

     The Company’s discussion and analysis of its financial condition and results of operations is based on its consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires Hercules to make estimates and assumptions that affect the amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Hercules evaluates its estimates on a regular basis, including those related to sales returns and allowances, bad debts, inventories, impairments of long-lived assets, income taxes, restructuring, contingencies, including litigation and environmental and pension and other benefit obligations. Hercules bases its estimates on various factors including

6

historical experience, consultation and advice from third party subject matter experts and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions and circumstances.

     Hercules believes that the following accounting estimates are critical due to the significant subjectivity and judgment necessary to account for the matters or the susceptibility of such matters to change and the affect of the estimates and assumptions on its consolidated financial statements.

     The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. Allowances for doubtful accounts are based on historical experience and known factors regarding specific customers and industries in which the customers operate. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances would be required.

     Aside from goodwill and intangible assets, which are tested for impairment under the guidance provided in SFAS 142, the Company has adopted SFAS 144 and tests other long-lived assets for impairment based on the guidance provided in SFAS 144. The Company records an impairment loss on its long-lived assets based on the excess of the carrying amount over fair value when expected future undiscounted cash flows are insufficient to recover the carrying amount of the asset. The fair value represents expected future cash flows from the use of the assets, discounted at the rate used to evaluate potential investments. If the Company determines that an impairment loss has occurred, the loss is recognized in the income statement. Deterioration in future economic conditions, poor operating results in a business or the determination that the long-lived asset is unsuitable for one reason or another, new or stronger competitors, or changes in technology could result in losses or the inability to recover the carrying value of the asset, thereby possibly requiring an impairment in the future.

     Hercules adopted the provisions of SFAS 142 effective January 1, 2002. Hercules identified the following reporting units: BetzDearborn, Pulp and Paper, Aqualon, FiberVisions and Pinova. In connection with Hercules’ transitional review, recorded goodwill was determined to be impaired in the BetzDearborn and FiberVisions reporting units. In the first quarter of 2002, Hercules completed its transitional impairment review of the identified reporting units and recognized an after-tax impairment loss of $349 million as a cumulative effect of a change in accounting principle. In addition, an after-tax impairment loss of $19 million was recognized in the first quarter of 2002 relating to the Company’s equity investment in CP Kelco, which had an impairment under SFAS 142. As a result of Hercules’ adoption of SFAS 142, the Company no longer records approximately $50 million of annual amortization relating to existing goodwill and intangibles. Pursuant to SFAS 142, the Company is required to perform an annual assessment of its reporting units for impairment. To assess impairment, the Company compares the reporting unit’s book value of net assets, including goodwill, to its fair value. Fair value is estimated using a combination of valuation approaches including the market value and income approaches. In the event that the book value exceeds the fair value, the Company recognizes an impairment to the extent the book value of goodwill exceeds the implied fair value of goodwill for any reporting unit, calculated by determining the fair value of the assets and liabilities for the reporting unit. Deterioration in future economic conditions, poor operating results in the reporting units, new or stronger competitors, or changes in technology could result in an inability to recover the carrying value of the goodwill and intangible assets, thereby requiring an impairment in the future.

     Hercules records a valuation allowance to reduce its deferred tax assets to an amount that is more likely than not to be realized after consideration of future taxable income and reasonable tax planning strategies. At December 31, 2003, the Company had gross deferred tax assets of approximately $734 million, including capital and operating loss carryforwards of $373 million. Valuation allowances of approximately $362 million have been set up on the total deferred tax assets. In the event that Hercules were to determine that it would not be able to realize all or part of its deferred tax assets, for which a valuation allowance had not been established, or is able to utilize capital and/or operating loss carryforwards for which a valuation allowance has been established, an adjustment to the deferred tax asset will be reflected in income in the period such determination is made.

     Hercules has and will continue to record charges for the estimated costs of employee severance and other exit costs pursuant to the Company’s strategy to continuously improve return on capital, streamline organizational structure, improve work processes and consolidate manufacturing and non-manufacturing resources. Since initiating the strategy in the third quarter 2001, the Company has recognized $83 million in charges for severance and other exit costs. In the event that it is determined that additional employees must be involuntarily terminated, or that additional manufacturing or non-manufacturing facilities must be closed pursuant to work process redesign or other cost reduction initiatives, supplemental reserves would be required, which would result in an incremental charge against earnings. In the event that the number of employees involuntarily terminated pursuant to restructuring plans is less than anticipated due to greater than anticipated voluntary resignations, an adjustment to reduce excess restructuring reserves would increase income in the period that the determination was made.

     Hercules establishes reserves for environmental matters, litigation and other contingencies when it is probable that a liability has been incurred and the amount of the liability is reasonably estimable. At December 31, 2003, the Company

7

had accrued $106 million for contingencies and asset retirement obligations in accordance with Statement of Financial Accounting Standards No. 5, “Accounting for Contingencies” (“SFAS 5”), and Statement of Financial Accounting Standards No. 143, “Accounting for Asset Retirement Obligations” (“SFAS 143”). The actual costs will depend upon numerous factors, including the number of parties found responsible at each environmental site and their ability to pay, the actual methods of remediation required or agreed to, outcomes of negotiations with regulatory authorities, outcomes of litigation, changes in environmental laws and regulations, technological developments, the years of remedial activity required, changes in the number or financial exposures of claims, lawsuits, settlements or judgments, or in the ability to reduce such financial exposures by collecting indemnity payments from insurers. If the contingency is resolved for an amount greater or less than has been accrued, or Hercules’ share of the contingency increases or decreases, or other assumptions relevant to the development of the estimate were to change, Hercules would recognize an additional expense or benefit in income in the period such determination was made.

     Hercules has established reserves for asbestos-related personal injury lawsuits and claims. Based on the results of a study the Company commissioned of its asbestos-related liability and considering amounts outstanding under previous settlements, the Company estimated that its reasonably possible financial exposure for these matters ranged from $220 million to $675 million, with no amount within this range representing a better estimate than any other amount. The Company’s estimates are based on a number of assumptions including the number of future claims, the timing and amount of future payments, disease, venue, the dynamic nature of asbestos litigation and the present uncertainty concerning the participation of its excess insurance carriers and other circumstances. At December 31, 2003, the Company has recorded a gross accrued liability of $221 million, reflecting the low end of the range and $1 million for previously settled but unpaid asbestos claims, for present and future potential asbestos claims before anticipated insurance recoveries. The Company believes that it is probable that $169 million of the $221 million accrual will be funded by or recovered from insurance carriers. That belief, which is subject to the various assumptions set forth herein, is based on many factors that have been evaluated by the Company, along with outside insurance counsel, including the indemnity and defense payments that have been made by its now exhausted insurance carriers, and by some of its other carriers, and the limits of remaining potentially available insurance coverage, as well as the range of possible outcomes in the Company’s insurance coverage litigation taking into account, among other considerations, the facts and status of that litigation, and the relevant case law.

     The Company provides defined benefit pension and postretirement welfare benefit plans to employees in the United States who meet eligibility requirements. Similar plans are provided outside the United States in accordance with local practice. Pension and other postretirement benefit obligations and the related expense (income) are determined based upon actuarial assumptions regarding mortality, medical inflation rates, discount rates, long-term return on assets, salary increases, Medicare availability and other factors. The assets of the U.S., United Kingdom (U.K.) and the Netherlands defined benefit plans constitute 84%, 4% and 11%, respectively, of the total defined benefits plan assets applicable to plans sponsored by the Company. In 2003, the actual return earned on U.S. plan assets exceeded the expected long-term rate of return assumption of 8.75%. The historical return on U.S. plan assets earned in 2001 and 2002 was less than the 9.25% expected long-term rate of return assumption. In addition, yields on long-term corporate bonds continued to decrease throughout 2003 and, pursuant to the Company’s annual review of the actuarial assumptions, the discount rate was lowered to 6.10% at December 31, 2003. Based on current assumptions, pension and postretirement benefit plan expenses for the years 2004, 2005 and 2006 are projected to be approximately $58 million, $73 million and $63 million. The projected increase in pension expense over 2003 in 2004, 2005 and 2006 is due to the decline in interest rates and the unfavorable performance of the pension investment portfolio over the period 2000 – 2002. The increase in 2005 and 2006 also assumes the adoption of the 1994 mortality table in 2005. The adoption of the 1994 mortality table increases pension and postretirement expense by approximately $9 million per year. The Company presently anticipates a decrease in consolidated pension and postretirement expense in 2006 (from 2005) as a result of favorable investment performance in 2003. As a result of past unfavorable investment performance and the lower discount rate, the accumulated benefit obligation (“ABO”) exceeded the fair value of plan assets at December 31, 2003. At December 31, 2003, the ABO of the U.S., U.K. and German defined benefit pension plans of $1,325 million, $67 million and $32 million, respectively, exceeded their funded benefits. The Company is required to recognize an additional liability equal to the sum of such excess plus the prepaid pension asset balance, with a corresponding after-tax charge to other comprehensive income in stockholders’ equity. At December 31, 2002, the Company recorded an additional minimum liability (“AML”) of $579 million (pre-tax) with an after-tax charge to other comprehensive income of $354 million. At December 31, 2003, the AML decreased $25 million to $554 million (pre-tax) and, accordingly, the change to accumulated other comprehensive income was decreased by $15 million to $339 million. At December 31, 2003, the consolidated projected benefit obligation was $1,702 million. A 100-basis point (1%) decrease or increase in the discount rate has approximately a plus or minus $193 million impact on the Company’s consolidated ABO. At the present time, the U.S. defined benefit pension plan is at a sufficient funding level as to not require ERISA mandated contributions. The Company has initiated a study to review plan changes that are expected to result in a reduction of future expenses and liabilities to its U.S. defined benefit final pay pension plan. The Company has decided, however, that it is in the best interests of the Company and its pension plan participants to make voluntary contributions to the plan. If the U.S. qualified pension plan performs in accordance with the actuarial assumptions, the Company presently anticipates making voluntary cash contributions of approximately $40 million per year over the next few years, including $40 million contributed to the U.S. defined benefit plan in January

2004. The Company also contributed $7 million to its non-U.S. pension plans in the fourth quarter 2003 to bring funding to required levels or to improve government mandated funding provisions.

Results of Operations

     The table below reflects net sales and profit from operations for continuing operations for the years ended December 31, 2003, 2002 and 2001. Results of operations for 2002 and 2001 have been restated for the Company’s change in accounting for its Employee Stock Ownership Plan (see Note 1).

2003 vs. 2002

     Net sales in 2003 increased 8% from 2002. Growth in sales for 2003 compared to 2002 was driven by a 6%, or $110 million, benefit from rate of exchange and a 2%, or $29 million, benefit from the consolidation of ES FiberVisions pursuant to FIN 46. The Euro appreciated approximately 20% in 2003 from 2002 levels. Volume and price in the aggregate were flat compared to 2002. Volumes were flat in Pulp and Paper, with declines in the weak North American and European markets offset by strong sales growth in the emerging regions of China, Brazil and Russia. Volume growth in Aqualon was a result of stronger demand in the oil and gas drilling and recovery markets. FiberVisions volume growth principally reflects the consolidation of ES FiberVisions. Lower volumes in the Pinova business were driven by lost business in its chewing gum and adhesives markets.

     Profit from operations improved 16% compared to 2002. Higher costs in 2003 for energy, raw materials and pension were more than offset by productivity improvements and the positive effect of the stronger Euro. Worldwide pension expense was approximately $28 million in 2003, an increase of $22 million versus 2002.

     In the Performance Products segment, net sales increased $98 million, or 7%. Net sales were positively impacted 6%, or $91 million, by rates of exchange. Profit from operations in the segment improved $19 million, or 8%, equal to the benefit from favorable rates of exchange. Cost increases in energy, raw materials and pension expense were offset by productivity improvements.

     In Pulp and Paper, net sales increased $37 million, or 4%, reflecting a $48 million positive impact from rates of exchange, principally the euro, and strong growth in emerging markets. Net sales were up 29% in China, 40% in Brazil and 17% in Russia. Net sales were negatively impacted by $11 million as a result of price erosion and unfavorable mix. Global volumes were essentially flat reflecting the impact of weak market conditions in North America. For 2003, paper and paperboard production was down 2% in North America. Office paper production in Europe, a key market for Hercules, was also down 2%. Factors impacting the North American industry include a declining manufacturing base as more production shifts off-shore to countries such as China, lower classified advertising (newsprint), lower weight magazines and a slowdown in print advertising and plastics substitutes for liquid packaging. Profit from operations was essentially flat, down $1 million versus 2002. Profit from operations was negatively impacted by higher energy and energy related raw materials in addition to pension expense. These higher costs, in part, were offset by supply chain improvements and lower selling, general and administrative expense.

     Aqualon’s net sales grew $61 million, or 11% compared to 2002. Rate of exchange, principally the Euro, had a $43 million, or 8%, favorable impact and volume/mix had an $18 million, or 3%, favorable impact. Volume growth was fueled by an increase in the construction, oil field and personal care businesses. Global price increases were implemented in the first half of 2003, partially offsetting higher raw material and energy costs. Profit from operations improved $20 million, or 14%, compared to 2002, driven by positive rate of exchange impact ($11 million or 8%) and volume increases even as the business experienced higher costs for energy, raw material and pension expense.

     In the Engineered Materials and Additives segment, net sales increased $43 million, or 13%. The consolidation of the ES FiberVisions joint ventures contributed $29 million, or 9%, to the improvement. Favorable impacts of rates of

9

exchange contributed $19 million, or 6%. Lower volumes in Pinova due to the lost business in its chewing gum and adhesives markets negatively impacted the segment’s net sales. Profit from operations decreased $9 million, or 50%, from 2002. Improvement in FiberVisions profit from operations was more than completely offset by negative profit from operations in Pinova.

     FiberVisions net sales increased $57 million, or 26%, over 2002, reflecting the positive impacts from the consolidation of the ES FiberVisions joint ventures of $29 million or 13%, rates of exchange of $19 million or 9%, and pricing and volume/mix totaling $9 million or 4%. FiberVisions has contractual arrangements with a majority of its customers that enables it to pass through higher polypropylene costs on a delayed basis. Lower volumes for fibers used in diapers were partially offset by higher volumes in the wipes markets. New wipes products generated approximately $23 million and new bicomponent products generated approximately $10 million in net sales. Profit from operations improved $3 million, or 30% over 2002. The consolidation of the ES FiberVisions joint ventures contributed $3 million to profit from operations.

     Pinova net sales decreased $14 million, or 14%, from 2002 reflecting a 13% decrease in volumes due to the lost business in its chewing gum and adhesives markets. Loss from operations was $4 million compared to an $8 million profit from operations in 2002. The business has a significant fixed cost structure that is not easily reduced. The business has been successful in regaining most of the lost volumes through increased sales to existing customers and the addition of new customers.

2002 vs. 2001

     Net sales were $1,705 million for 2002, a decrease of $71 million, or 4%. Net sales in 2002 were favorably impacted by approximately $16 million reflecting the positive impact of the weaker dollar. Approximately $113 million of the decrease is attributable to the businesses comprising the Resins divestitures (see Note 25). Volumes declined 6% year over year. Regionally, net sales declined 6% in North America and 14% in Latin America, remained flat in Europe and improved 2% in Asia Pacific.

     Profit from operations increased $36 million, or 20%. Profit from operations in 2002 was favorably impacted by approximately $3 million, reflecting the positive impact of the weaker dollar. Improvement in operating profit occurred in all businesses despite a 6% decline in volumes. This was principally due to reductions in the Company’s fixed cost structure pursuant to the comprehensive cost reduction and work process redesign program (see Notes 18 and 19) initiated in 2001. On an annualized basis, approximately $160 million in fixed cost savings were achieved as of December 31, 2002 (as compared to 2000 results, excluding the Food Gums business, the Resins divestitures and the Water Treatment Business). Impacting 2002 profit from operations were $23 million in net restructuring charges, $7 million in asset impairment charges and $5 million, net, of other charges. Impacting profit from operations in 2001 were $74 million of pre-tax gains from the Resins divestitures and $6 million, net, of other gains, partially offset by $51 million in restructuring charges associated with the comprehensive cost reduction and work process redesign program.

     Performance Products segment revenues were up $34 million, or 3%. Net sales were favorably impacted by approximately $12 million, reflecting the positive impact of the weaker dollar. Sales improved due to volume improvements of 6% versus the prior year and favorable product mix, partially offset by competitive pricing. Profit from operations increased $89 million, or 58%. Profit from operations primarily benefited from the cost reduction and work process redesign program commenced in 2001. Profit from operations in 2002 included asset impairment charges of $7 million associated with the planned shutdown of plant facilities.

     In Pulp and Paper, both net sales and profit from operations improved year over year. Sales improved due to volume improvements of 10% versus the prior year partially offset by competitive pricing and unfavorable product mix. Sales to GE Betz pursuant to a two-year supply agreement accounted for 2% of the net sales growth. Lower overhead costs attributable to the cost reduction and work process redesign program was the primary driver of higher profit from operations. Profit from operations was negatively impacted by asset impairment charges of $7 million associated with the shutdown of two plant facilities.

     Aqualon’s net sales and profit from operations improved versus the prior year, despite a decrease in volumes of approximately 2%. Sales improved due to favorable product mix partially offset by lower volumes and competitive pricing. Volume declines were reflective of weak sales to the oilfield industry. Lower raw material costs and lower overhead costs attributable to the cost reduction and work process redesign program were the primary drivers of the improved operating performance.

     Engineered Materials and Additives segment revenues decreased $105 million, or 25%, and profit from operations increased $7 million, or 64%. Net sales decreased $113 million as a result of the Resins divestitures. In May 2001, Hercules sold its hydrocarbon resins and select portions of its rosin resins businesses, its peroxy chemicals business and its interest in a toner resin joint venture (see Note 25). Segment volumes decreased 24% year over year, again reflecting the Resins business divestitures.

10

     Net sales in FiberVisions improved marginally, largely driven by a positive rate of exchange effect and 5% higher volumes partially offset by the contractual customer pass through of lower polypropylene costs and competitive pricing issues. Operating performance increased by $3 million due to lower polymer costs and lower overhead costs attributable to the cost reduction and work process redesign program.

     Net sales in Pinova significantly declined in 2002 versus the prior year as a result of the resins divestitures (see Note 25). Volumes were down approximately 65%. Despite declines in revenues and volumes, operating performance increased. The improvement in profit from operations was a direct result of hiring a full time sales team to support the business, replacing the distribution channel used in 2001 following the Resins divestitures, as well as a focused effort on cost reduction and work process redesign.

Interest and Debt Expense and Preferred Security Distributions; Equity Income (Loss); Provision for Income Taxes

     Interest and debt expense including preferred security distributions of subsidiary trusts decreased $26 million, or 17%, in 2003 versus 2002 reflecting lower outstanding debt balances. In the fourth quarter of 2003, the Company repurchased 46,000 of the CRESTS Units for $34 million, of which $27 million was attributable to the preferred security component and $7 million was attributable to the warrants. In addition, the Company purchased $24 million of the 11 1/8% senior notes, recognizing a loss of $5 million. Interest and debt expense and preferred security distributions decreased $105 million, or 40%, in 2002 versus 2001 primarily due to lower outstanding debt balances, reflecting the application of proceeds from the sale of the BetzDearborn Water Treatment Business on April 29, 2002, and 2001 asset sales, as well as lower interest rates.

     Equity income (loss) of affiliated companies in 2002 reflected equity income from the FiberVisions ES joint venture that FiberVisions formed in January 2000 with Chisso Polypro Fiber Co., Ltd. The equity losses recorded in 2001 were a result of the equity losses relating to CP Kelco.

     The provision for income taxes on continuing operations reflects effective tax rates of 22% in 2003, 6% in 2002 and (16%) in 2001. The effective tax rate for 2003 reflects the tax benefit from the donation of intellectual property to qualified organizations and the use of prior year capital losses. The effective tax rate for 2002 reflects the tax benefit of the pre-tax loss partially offset by the effect of increases to tax reserves related to anticipated tax assessments and other provisions. The effective tax rate for 2001 reflects the tax benefit of the pre-tax loss partially offset by the effect of increases to tax reserves and the effect of non-deductible goodwill amortization.

Financial Condition

     Liquidity and financial resources: Net cash flow provided by (used in) operations was $23 million in 2003, $(215) million in 2002 and $(98) million in 2001. The improvement in operating cash flow in 2003 compared to 2002 reflects significantly lower payments for income taxes, defined benefit pension plan contributions, interest, severance and debt repayment penalties. The decrease in tax payments primarily related to taxes paid on the BetzDearborn divestiture. The Company paid approximately $15 million in taxes related to this transaction in 2003; the remaining taxes are estimated to be between $11 million and $21 million and are expected to be paid in 2005. The Company made contributions to its defined benefits pensions plans of $55 million and $92 million in 2003 and 2002, respectively. Restructuring and severance payments were $21 million in 2003 versus $39 million in 2002. The Company presently anticipates severance payments of approximately $10 million in 2004. Partially offsetting these cash flow improvements is an increase in asbestos settlement payments. As noted, the Company has exhausted its primary and first level excess insurance policies that provided coverage for the asbestos-related matters. The Company has not yet reached agreement with its other insurance carriers to fund the cost of defending and resolving its asbestos-related matters. As a result, until the Company’s other insurance carriers begin to fund the cost of defending and resolving these matters, the Company will have to fully fund the cost of defending and resolving these matters. Net of insurance, the Company spent $40 million during 2003, which includes $7 million for defense costs. The Company presently projects asbestos-related payments of approximately $40 to $45 million in 2004 before consideration of any insurance coverage or reimbursement, if any, and any potential legislative resolution to this matter. The change in cash in 2002 compared to 2001 primarily results from higher income tax payments, $92 million in pension contributions and payments related to the restructuring plans.

     Net cash provided by investing activities was $48 million in 2003, $1,659 million in 2002 and $295 million in 2001. In June 2003, the Company used the $125 million in escrowed funds from its December 2002 refinancing to redeem the 6.625% notes. On December 1, 2003 the Company completed the acquisition of Quantum for approximately $10 million. As a result of the de-consolidation of Hercules Trust I and Hercules Trust II, pursuant to FIN 46(R), the Company has an investment of $27 million in CRESTS Units preferred securities at December 31, 2003. Hercules’ significant cash flow from investing activities in 2002 was due to the sale of the BetzDearborn Water Treatment Business. Cash flow from investing activities in 2001 benefited from the monetization of certain non-core assets. In May 2001, the Company completed the sale of its hydrocarbon resins business and select portions of its rosin resins business to a subsidiary of Eastman Chemical Company, receiving proceeds of approximately $244 million, and the sale of its peroxy chemicals business to GEO Specialty Chemicals, Inc., receiving proceeds of approximately $92 million. Capital expenditures were $48 million, $43 million and $52 million, in 2003, 2002 and 2001, respectively. Significant capital spending controls

11

instituted in early 2001 lowered capital expenditures in 2003, 2002 and 2001. The decrease in capital expenditures in 2002 from 2001 also reflects completion of the plant expansion in Doel, Belgium in early 2001.

     Net cash used in financing activities was $171 million, $1,334 million and $370 million, respectively, in 2003, 2002 and 2001. The Company has used cash provided by operations in 2003, the December 2002 refinancing and the business divestitures in 2002 and 2001 to pay down long-term debt.

     The Board of Directors has authorized the Company, from time to time, subject to market conditions and provisions of the Company’s credit agreement, to repurchase up to $140 million of its outstanding indebtedness. Pursuant to the Term B Loan Credit Agreement and subject to related covenants, the Company has the right to use available cash to repurchase, repay or otherwise redeem up to $100 million of the 11 1/8% senior notes and $40 million of the company-obligated trust preferred securities in any fiscal year. During the fourth quarter ended December 31, 2003, the Company repurchased $24 million (book value) of its 11 1/8% senior notes for $29 million, recognizing a loss of $5 million. Subsequently, in 2004, an additional $33 million (book value) of the 11 1/8% senior notes have been repurchased by the Company at a cost of $40 million.

     In addition, during the fourth quarter of 2003, the Company purchased 46,000 of the CRESTS Units for a total of $34 million, of which $27 million was attributed to the preferred security component and $7 million was attributed to the warrants. The corresponding book value of a similar number of the CRESTS Units junior subordinated deferrable interest debentures was $34 million. Accordingly, the Company recognized a gain of $7 million ($5 million after-tax) in continuing operations. However, the Company has determined that (i) Hercules Trust I and Hercules Trust II (the “Trusts”) are variable interest entities and (ii) the Company is not the primary beneficiary of the Trusts. Accordingly, the Company has de-consolidated the Trusts and recognized an after-tax loss of $5 million as a cumulative effect of a change in accounting principle to defer the above noted gain, effective December 31, 2003, in accordance with the provisions of FASB Interpretation No. 46 (revised December 2003), “Consolidation of Variable Interest Entries” (“FIN 46R”). As a result of the de-consolidation, long-term debt reflects the Company’s obligation to Hercules Trust II for the CRESTS Units junior subordinated deferrable interest debentures (long-term debt at December 31, 2003 also reflects the Company’s obligations to Hercules Trust I on the TOPrS 9.42% junior subordinated deferrable interest debentures). The indenture for the CRESTS Units junior subordinated deferrable interest debentures does not provide the ability for the Company to repay, redeem or defease the CRESTS Units junior subordinated deferrable interest debentures through purchasing the CRESTS Units. Accordingly, at December 31, 2003 the outstanding balance of CRESTS Units junior subordinated deferrable interest debentures has not changed as a result of the Company’s purchase of the CRESTS Units. The $27 million paid to purchase the CRESTS Units preferred security component is reflected as an increase in the Company’s investment in Hercules Trust II, with the corresponding gain on the purchase deferred until Hercules Trust II has been liquidated. The $7 million paid and attributable to the warrants has been recorded as a reduction in additional paid-in-capital.

     On December 17, 2003, the Company amended its senior credit facility to, among other things, (i) lower the term B loan interest to LIBOR + 2.50% (from LIBOR +3.25%) and (ii) provide the ability for foreign borrowings. On December 20, 2002, the Company completed a refinancing of its then existing senior credit facility with a new senior credit facility. The senior credit facility consists of a four year $125 million revolving credit agreement and a $200 million term B loan due May 2007. In addition, the Company has the option of borrowing an additional $50 million to $150 million on terms identical to the term B loan. The availability of the incremental term loan does not expire until the earlier of December 20, 2005 or the repayment of the $200 million term B loan. In conjunction with the execution of the credit agreement, $125 million of the proceeds of the term B loan was placed into an escrow account to pay the principal amount of the 6.625% notes in June 2003. The remaining proceeds from the refinancing were used for general corporate purposes. The term B loan bears interest at LIBOR + 2.50% (4.02% at December 31, 2003). The revolving credit agreement bears interest at LIBOR plus an applicable margin, currently 2.75%, which is determinable based on the Company’s leverage ratio. The senior credit facility is secured by liens on the Company’s U.S. assets (including real, personal and intellectual properties) and is guaranteed by substantially all of the Company’s current and future wholly-owned domestic subsidiaries. Issuance costs related to the financing are included in deferred charges and other assets and are being amortized over the term of the loans, using the effective interest method.

     The Company used the net proceeds of approximately $1.7 billion from the sale of the BetzDearborn Water Treatment Business (see Note 25) to permanently reduce long-term debt, repaying in full the following borrowings: term loan tranche A, term loan tranche D, the revolving credit agreement and the ESOP credit facility. In addition, effective with the consummation of the sale of the Water Treatment Business and the application of the net proceeds, the revolving credit agreement was permanently reduced from $900 million to $200 million and the Canadian revolving credit agreement was cancelled. A portion of the net proceeds ($73 million) from the sale of the Water Treatment Business was used to collateralize the Company’s then outstanding letters of credit.

     As of December 31, 2003, $49 million of the $125 million revolving credit agreement and $17 million of short-term lines of credit was available for use. The Company had outstanding letters of credit associated with the revolving credit agreement of $76 million at December 31, 2003.

12

Capital Structure and Commitments

     Total capitalization (stockholders’ equity (deficit) and debt including the junior subordinated deferrable interest debentures) is $1.4 billion and $1.3 billion at December 31, 2003 and 2002, respectively. Total debt, including junior subordinated deferrable interest debentures related to the company-obligated trust preferred securities, was $1.348 billion at December 31, 2003, a decrease of $159 million from December 31, 2002, reflecting the repayment of the 6.625% notes in June 2003 and repurchases of the 11 1/8% senior notes in the fourth quarter 2003. Total capitalization at December 31, 2002 decreased from $3.5 billion at December 31, 2001 principally as a result of the BetzDearborn divestiture. The current ratio increased to 1.79 at December 31, 2003, compared to 1.58 at December 31, 2002. The quick ratio increased to 1.39 at December 31, 2003 compared to 1.30 at December 31, 2002.

     Capital expenditures are estimated to be between $65 and $70 million in 2004 and $70 to $75 million in 2005. Capital expenditures are presently estimated to be approximately $60 million per year in 2006 through 2008. As previously announced, the Company is expanding its Natrosol HEC production capacity at facilities in New Jersey, Virginia and the Netherlands.

     The Company’s contractual commitments as of December 31, 2003 are summarized as follows:

     The Company had the following commercial commitments at December 31, 2003: lines of credit of $17 million outstanding and letters of credit of $76 million, both of which may require payments in the future. If required, these commitments would be funded from general corporate funds.

     The Company projects cash flow from operations will be sufficient to meet its investing and financing requirements in the next several years. The Company presently is in discussions to refinance a portion of its debt. The proposed refinancing, if implemented, is expected to reduce interest expense and extend 2007 debt maturities to future years.

Risk Factors

Indebtedness

     As of December 31, 2003, the Company’s total debt was approximately $1,348 million, of which 83% is fixed rate indebtedness. The Company’s indebtedness has significant consequences. For example, it could: increase the Company’s vulnerability to economic downturns and competitive pressures; require the Company to dedicate a substantial portion of its cash flow from operations to payments on its indebtedness, thereby reducing the availability of its cash flow to fund working capital, capital expenditures, research and development efforts and other general corporate purposes; limit the Company’s flexibility in planning for, or reacting to, changes in its business and the industries in which it operates or in pursuing attractive business opportunities requiring debt financing; place the Company at a disadvantage to its competitors that have less debt; and limit the Company’s ability to borrow additional funds due to restrictive covenants.

     The senior credit facility and the indenture governing the 11 1/8% senior notes due 2007, which together account for a large portion of the Company’s debt, contain numerous restrictive covenants, including, among other things, covenants that limit the Company’s ability to: borrow money and incur contingent liabilities; make dividend or other restricted payments; use assets as security in other transactions; enter into transactions with affiliates; enter into new lines of business; issue and sell stock of restricted subsidiaries; sell assets or merge with or into other companies and make capital expenditures. In addition, the senior credit facility requires the Company to meet financial ratios and tests, including

13

maximum leverage and interest coverage levels. These restrictions could limit the Company’s ability to plan for or react to market conditions or meet extraordinary capital needs and could otherwise restrict corporate activities.

     The Company’s ability to comply with the covenants and other terms of the senior credit facility and the indenture governing the senior notes and to satisfy these and other debt obligations will depend upon the Company’s current and future performance. The Company’s performance is affected by general economic conditions and by financial, competitive, political, business and other factors, many of which are beyond the Company’s control. The Company believes that the cash generated from its business will be sufficient to enable the Company to comply with the covenants and other terms of the senior credit facility and the indenture governing the senior notes and to make debt payments as they become due.

     The Company and its subsidiaries may incur additional indebtedness in the future. As of December 31, 2003, the Company had a $325 million senior credit facility with a syndicate of banks. Under the senior credit facility, the Company has a $125 million revolving credit agreement, which permits certain additional borrowings. In addition, the Company has the option to borrow an additional $50 million to $150 million under the senior credit facility. If new indebtedness is added to the Company’s current indebtedness levels, the risks described above could increase.

Market Risk

     Fluctuations in interest and foreign currency exchange rates affect the Company’s financial position and results of operations. The Company has used several strategies to actively hedge interest rate and foreign currency exposure and minimize the effect of such fluctuations on reported earnings and cash flow (see “Foreign Currency Translation” and “Derivative Financial Instruments and Hedging” in the Summary of Significant Accounting Policies and Notes 21 and 24). Sensitivity of the Company’s financial instruments to selected changes in market rates and prices, which are reasonably possible over a one-year period, are described below. The market values for interest rate risk are calculated by the Company utilizing a third-party software model that employs standard pricing models to determine the present value of the instruments based on the market conditions as of the valuation date.

     The Company’s derivative and other financial instruments subject to interest rate risk consist substantially of debt instruments and trust preferred securities. At December 31, 2003 and 2002, net market value of these combined instruments was a liability of $1.386 billion and $1.440 billion, respectively. The sensitivity analysis assumes an instantaneous 100-basis point move in interest rates from their levels, with all other variables held constant. A 100-basis point increase in interest rates at December 31, 2003 and 2002 would result in an $85 and $60 million decrease, respectively, in the net market value of the liability. A 100-basis point decrease in interest rates at December 31, 2003 and 2002 would result in a $68 and $72 million increase, respectively, in the net market value of the liability.

     Our financial instruments subject to foreign currency exchange risk consist of foreign currency forwards and options and represent a net asset position of $1.0 million and $0.2 million at December 31, 2003 and 2002, respectively. The following sensitivity analysis assumes an instantaneous 10% change in foreign currency exchange rates from year-end levels, with all other variables held constant. A 10% strengthening of the U.S. dollar versus other currencies at December 31, 2003 and 2002 would result in a $0.1 million decrease and a $0.2 million increase, respectively, in the net asset position while a 10% weakening of the dollar versus all currencies would result in a $0.1 million increase and a $0.3 million decrease, respectively, in the net asset position.

     Foreign exchange forward and option contracts have been used to hedge the Company’s firm and anticipated foreign currency cash flows. Thus, there is either an asset or cash flow exposure related to all the financial instruments in the above sensitivity analysis for which the impact of a movement in exchange rates would be in the opposite direction and substantially equal to the impact on the instruments in the analysis. There are presently no significant restrictions on the remittance of funds generated by the Company’s operations outside the United States.

     The Company has not designated any derivative as a hedge instrument under Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”) and, accordingly, changes in the fair value of derivatives are recorded each period in earnings.

Environmental

     In the ordinary course of its business, the Company is subject to numerous environmental laws and regulations covering compliance matters or imposing liability for the costs of, and damages resulting from, cleaning up sites, past spills, disposals and other releases of hazardous substances. Changes in these laws and regulations may have a material adverse effect on the Company’s financial position and results of operations. Any failure by the Company to adequately comply with such laws and regulations could subject the Company to significant future liabilities.

     Environmental remediation expenses are funded from internal sources of cash. Such expenses are not expected to have a significant effect on the Company’s ongoing liquidity. Environmental cleanup costs, including capital expenditures for ongoing operations, are a normal, recurring part of operations and are not significant in relation to total operating costs or cash flows (see Item 3, Legal Proceedings and Note 13).

14

Litigation

     Hercules is a defendant in numerous lawsuits that arise out of, and are incidental to, the conduct of its business. These suits concern issues such as product liability, contract disputes, labor-related matters, patent infringement, antitrust proceedings, environmental proceedings, property damage and personal injury matters. While it is not feasible to predict the outcome of all pending suits and claims, the ultimate resolution of these matters could have a material effect upon the financial position of Hercules, and the resolution of any of the matters during a specific period could have a material effect on the quarterly or annual operating results for that period (see Item 3, Legal Proceedings and Note 13).

Pension

     The assets and liabilities associated with the Company’s defined benefit plans are subject to interest rate and market risk. A 100-basis point decrease or increase in the discount rate has approximately a plus or minus $193 million impact on the ABO. A 100-basis point decrease or increase in the assumed rate of return has approximately a plus or minus $10 million impact on the U.S. pension and postretirement expense estimated for 2004 (see Note 9).

Indemnifications

     In connection with the sale of certain Company assets or businesses, the Company has indemnified respective buyers against certain liabilities that may arise in connection with the sales transactions and business activities prior to the ultimate closing of the sale. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters. If the indemnified party were to incur a liability or have a liability increase as a result of a successful claim, pursuant to the terms of the indemnification, the Company would be required to reimburse the buyer. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. The carrying amount recorded for all indemnifications as of December 31, 2003 is $76 million. Although it is possible that future payments may exceed amounts accrued, due to the nature of indemnified items, it is not possible to make a reasonable estimate of the maximum potential loss or range of loss.

Recent Accounting Pronouncements

     In December 2003, the SEC issued SAB 104, “Revenue Recognition,” which supersedes SAB 101, “Revenue Recognition in Financial Statements,” and updates portions of the interpretive guidance included in Topic 13 of the codification of staff accounting bulletins in order to make this interpretive guidance consistent with current authoritative accounting guidance. The Company had previously adopted the necessary changes incorporated into SAB 104, which did not have a material effect on the Company’s financial position, results of operations or cash flows.

     In January 2004, the FASB issued Staff Position FAS 106-1, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003” (“FSP 106-1”). FSP 106-1 permits a sponsor of a postretirement health care plan that provides a prescription drug benefit to make a one-time election to defer accounting for the effects of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Medicare Act”). The Medicare Act, which was signed by the President on December 8, 2003, introduces a prescription drug benefit under Medicare (Medicare Part D) as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D.

     The Company offers a drug benefit plan and has elected to defer current recognition of the effects of the Act in the accounting for its plan pursuant to FSP 106-1 until authoritative guidance on the accounting for the federal subsidy is issued. As such, any measures of the accumulated projected benefit obligation or net periodic postretirement benefit cost in the financial statements or accompanying notes do not reflect the effects of the Act on the plan, and as the specific authoritative guidance on the accounting for the federal subsidy is still pending, it is possible that when guidance is issued it could require the Company to change previously reported information.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
of Hercules Incorporated:

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) on page 79 present fairly, in all material respects, the financial position of Hercules Incorporated and subsidiaries at December 31, 2003 and 2002, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2003 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) on page 79 presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and the financial statement schedule are the responsibility of the Company’s management; our responsibility is to express an opinion on these financial statements and the financial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 1 to the consolidated financial statements, during the year ended December 31, 2003, the Company changed its method of accounting for its employee stock ownership plan from the method prescribed by Statement of Position 76-3, “Accounting Practices for Certain Employee Stock Ownership Plans,” to the method prescribed by Statement of Position 93-6, “Employers’ Accounting for Employee Stock Ownership Plans.”

Summary of Significant Accounting Policies

Principles of Consolidation

     The Consolidated Financial Statements include the accounts of Hercules, all majority-owned subsidiaries where control exists, any other subsidiaries which it controls and variable interest entities (“VIEs”) in which Hercules is the primary beneficiary. Following the acquisition of BetzDearborn and continuing through December 31, 2002, the Company continued BetzDearborn’s practice of using a November 30 fiscal year-end for certain former BetzDearborn non-U.S. subsidiaries to expedite the year-end closing process. As of December 31, 2003, these subsidiaries have adopted a December 31 fiscal year-end. All intercompany transactions and profits have been eliminated. Investments in affiliated companies, where Hercules has a 20% to 50% interest and where the entity is either not a VIE or Hercules is not the primary beneficiary, are accounted for using the equity method of accounting and, accordingly, consolidated income includes Hercules’ share of their income. Subsidiaries of the Company (Hercules Trust I and Hercules Trust II) that are VIEs and with respect to which Hercules is not the primary beneficiary have been de-consolidated as of December 31, 2003.

Use of Estimates

     Preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. Actual results could differ from these estimates.

Revenue Recognition

     The Company recognizes revenue when the earnings process is complete. This generally occurs when products are shipped to the customer or services are performed in accordance with terms of the agreement, title and risk of loss have been transferred, collectibility is probable and pricing is fixed or determinable. Revenue arrangements with multiple deliverables are reported separately for deliverables that have stand-alone value when there is objective and reliable evidence as to the fair value of the deliverable and the delivery of any undelivered item is probable and substantially controlled by the Company. Approximately 12%, 12% and 11% of the Company’s revenues for the years ended December 31, 2003, 2002 and 2001, respectively, are from consignment inventory. For consignment inventory, title and risk of loss are transferred when the earnings process is considered complete, which generally occurs when the Company’s products have been consumed or used in the customer’s production process. Accruals are made for sales returns and other allowances based on the Company’s experience. The corresponding shipping and handling costs are included in cost of sales.

Research and Development Expenditures

     Research and development expenditures are expensed as incurred.

Environmental Expenditures

     The Company has ongoing expenditures for environmental related projects at current and former operating facilities. Accruals for environmental remediation matters are expensed when it is probable that a liability has been incurred and the amount of the liability is reasonably estimable. The Company capitalizes environmental expenditures for projects that extend the life, increase the capacity or improve the safety or efficiency of Company facilities. In addition, the Company capitalizes asset retirement obligations relating to environmental remediation liabilities that result from the normal operation of Company facilities. The Company capitalized environmental related expenditures and asset retirement obligations totaling $1.9 million, $0.9 million and $2.7 million for the years ended December 31, 2003, 2002 and 2001, respectively.

Cash and Cash Equivalents

     Cash in excess of operating requirements is invested in short-term, income-producing instruments. Cash equivalents include commercial paper and other securities with original maturities of 90 days or less. Book value approximates fair value because of the short maturity of those instruments.

Inventories

     Inventories are stated at the lower of cost or market. A portion of domestic inventories are valued on the last-in, first-out (“LIFO”) method. Foreign and certain domestic inventories, which in the aggregate represented 84% of total inventories at December 31, 2003 and 2002, are valued principally on the average-cost method. Elements of costs in inventories include raw materials, direct labor and manufacturing overhead.

Property and Depreciation

     Property, plant and equipment are stated at cost. The Company changed to the straight-line method of depreciation, effective January 1, 1991, for newly acquired processing facilities and equipment. Assets acquired before

23

Hercules Incorporated
Summary of Significant Accounting Policies

then continue to be depreciated by accelerated methods. The Company believes straight-line depreciation provides a better matching of costs and revenues over the lives of the assets. The estimated useful lives of depreciable assets are as follows: buildings – 30 years; plant machinery and equipment – 15 years; other machinery and equipment – 3 to 15 years.

     Maintenance, repairs and minor renewals are expensed as incurred; major renewals and betterments are capitalized. Upon normal retirement or replacement, the net book value of property (less proceeds of sale or salvage) is charged to income.

Goodwill and Other Intangible Assets

     Pursuant to Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”), beginning January 1, 2002, goodwill is not amortized but is tested for impairment at least annually with any necessary adjustment charged to expense. The Company has selected November 30 as the date for performing the annual impairment test. Prior to January 1, 2002, goodwill and other intangible assets have been amortized on a straight-line basis over the estimated future periods to be benefited, generally 40 years for goodwill, customer relationships, trademarks and tradenames and 5 to 15 years for other intangible assets. Intangible assets with finite lives are amortized over their useful lives.

Investments

     Investments in affiliated companies in which the Company has a 20% to 50% interest and exercises significant influence are accounted for using the equity method of accounting. Accordingly, these investments are included in deferred charges and other assets on the Company’s consolidated balance sheet and the income or loss from these investments is included in equity income (loss) of affiliated companies in the Company’s Consolidated Statement of Operations.

     Investments in affiliated companies in which the Company does not have a controlling interest, or an ownership and voting interest so large as to exert significant influence, are accounted for using the cost method of accounting. Accordingly, these investments are included in deferred charges and other assets on the Company’s Consolidated Balance Sheet.

     Other investments include non-current marketable securities whose value approximates market value.

Investments in Subsidiary Trusts

     The Company has two subsidiary trusts, Hercules Trust I and Hercules Trust II, that are variable interest entities for which the Company is not the primary beneficiary. The Company utilizes the cost method to account for its investments in the subsidiary trusts.

Long-lived Assets

     The Company reviews its long-lived assets, including other intangibles, for impairment on an exception basis whenever events or changes in circumstances indicate carrying amounts of the assets may not be recoverable through undiscounted future cash flows. If an impairment loss has occurred based on expected future cash flows (undiscounted), the loss is recognized in the income statement. The amount of the impairment loss is the excess of the carrying amount of the impaired asset over the fair value of the asset. The fair value represents expected future cash flows from the use of the assets, discounted at the rate used to evaluate potential investments. The Company reviews its long-lived assets under Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS 144”).

Computer Software Costs

     The Company follows the American Institute of Certified Public Accountants Statement of Position 98-1, “Accounting for the Cost of Computer Software Developed or Obtained for Internal Use” (“SOP 98-1”). The Company’s prior accounting was generally consistent with the requirements of SOP 98-1 and, accordingly, adoption of SOP 98-1 had no material effect. Computer software costs are being amortized over a period of 5 to 10 years.

Deferred Financing Costs

     The Company capitalizes costs associated with the issuance of debt (deferred financing costs), including bank, legal, investment advisor and accounting fees and other expenses. Deferred financing costs are amortized over the term of the related financing transaction using the effective interest rate method.

24

Hercules Incorporated
Summary of Significant Accounting Policies

Income Taxes

     The provision for income taxes has been determined using the asset and liability approach for accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income tax represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.

Asset Retirement Obligations

     The Company records a liability at fair value for legal obligations associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal operations of a long-lived asset. The Company’s asset retirement obligations principally relate to environmental remediation liabilities associated with current and former operations that were incurred during the course of normal operations.

Foreign Currency Translation

     The financial statements of Hercules’ non-U.S. entities are translated into U.S. dollars using current rates of exchange, with gains or losses included in accumulated other comprehensive losses.

Derivative Instruments and Hedging

     On January 1, 2001, the Company adopted Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”). SFAS 133, as amended by Statement No. 137, “Accounting for Derivative Instruments and Hedging Activity – Deferral of the Effective Date of FASB Statement No. 133, “Statement No. 138, “Accounting for Certain Derivative Instruments and Certain Hedging Activities,” and Statement No. 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities,” requires that all derivative instruments be recorded on the balance sheet at their fair values. The Company has not designated any derivative as a hedge instrument and accordingly, changes in fair value of derivatives are recorded each period in earnings. The adoption of SFAS 133 did not result in a pre-tax or post-tax cumulative-effect-type adjustment to income and did not result in a change to other comprehensive losses. Under procedures and controls established by the Company’s risk management policies, the Company strategically enters into contractual arrangements (derivatives) in the ordinary course of business to reduce the exposure to foreign currency rates and interest rates.

     The Company’s risk management policies establish several approved derivative instruments to be utilized in each risk management program and the level of exposure coverage based on the assessment of risk factors. Derivative instruments utilized include forwards, swaps and options. The Company uses forward exchange contracts and options, generally no greater than three months in term, to reduce its net currency exposure. The objective of this program is to maintain an overall balanced position in foreign currencies so that exchange gains and losses resulting from exchange rate changes are minimized. The Company has used interest rate swap agreements to manage interest costs and risks associated with changing rates. The Company has not designated any non-derivatives as hedging instruments.

     Counterparties to the forward exchange, currency swap, options and interest swap contracts are major financial institutions. Credit loss from counterparty nonperformance is not anticipated.

Stock-based Compensation

     Effective January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”), as amended by Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation – Transition and Disclosure” (“SFAS 148”). SFAS 148 amends SFAS 123 by providing alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation and requiring enhanced disclosure regarding stock-based compensation. The Company has elected to apply the fair value recognition provisions of SFAS 123 on a prospective basis to all employee awards granted, modified or settled after January 1, 2003. Awards under the Company’s stock-based compensation plans vest over periods ranging from 1 to a maximum of 10 years; however, vesting can be extended with the approval of the Board of Directors. Therefore, the cost related to stock-based employee compensation included in the determination of net income in 2003 is less than that which would have been recognized if the fair value based method had been applied to all awards since the original effective date of SFAS 123. The Company did not grant any stock options pursuant to SFAS 123, as amended by SFAS 148, to employees in 2003. However, the Company did make grants of restricted stock to employees in 2003. Restricted stock awards under the Hercules Long-term Incentive Compensation Plan are valued at the quoted market price (fair value) of the Company’s stock on the grant date (measurement date). Stock acquired through the Employee Stock Purchase Plan and “above target” restricted stock awarded under the Hercules

25

Hercules Incorporated
Summary of Significant Accounting Policies

Management Incentive Compensation Plan is discounted 15% from market price as permitted by IRS regulations and the provisions of the Company’s incentive compensation plans. The value of the award and the discount, if any, are amortized into expense over the vesting (restriction) period. Forfeitures are recorded as incurred. The Company recognized $4 million, $1 million and $2 million of expense in 2003, 2002 and 2001, respectively, in connection with restricted stock awards.

     Pursuant to the disclosure requirements of SFAS 123, as amended by SFAS 148, the following table presents the pro forma effect on net income (loss) and earnings (loss) per share assuming the Company had applied the fair value recognition provisions of SFAS 123 to all stock-based employee compensation on a retroactive basis.

Recent Accounting Pronouncements

     In December 2003, the SEC issued SAB 104, “Revenue Recognition,” which supersedes SAB 101, “Revenue Recognition in Financial Statements,” and updates portions of the interpretive guidance included in Topic 13 of the codification of staff accounting bulletins in order to make this interpretive guidance consistent with current authoritative accounting guidance. The Company had previously adopted the necessary changes incorporated into SAB 104, which did not have a material effect on the Company’s financial position, results of operations or cash flows.

     In January 2004, the FASB issued Staff Position FAS 106-1, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003” (“FSP 106-1”). FSP 106-1 permits a sponsor of a postretirement health care plan that provides a prescription drug benefit to make a one-time election to defer accounting for the effects of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Medicare Act”). The Medicare Act, which was signed by the President on December 8, 2003, introduces a prescription drug benefit under Medicare (Medicare Part D) as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D.

     The Company offers a prescription drug benefit plan and has elected to defer current recognition of the effects of the Act in the accounting for its plan pursuant to FSP 106-1 until authoritative guidance on the accounting for the federal subsidy is issued. As such, any measures of the accumulated projected benefit obligation or net periodic postretirement benefit cost in the financial statements or accompanying notes do not reflect the effects of the Act on the plan and, as the specific authoritative guidance on the accounting for the federal subsidy is still pending, it is possible that when guidance is issued it could require the Company to change previously reported information.

Reclassifications

     Certain amounts in the 2002 and 2001 consolidated financial statements and notes have been reclassified to conform to the 2003 presentation.

26

Hercules Incorporated
Notes to Consolidated Financial Statements

     During the year ended December 31, 2003, the Company changed its method of accounting for its Employee Stock Ownership Plan (“ESOP”) from the method prescribed by Statement of Position 76-3, “Accounting Practices for Certain Employee Stock Ownership Plans,” (“SOP 76-3”) to the method prescribed by Statement of Position 93-6 “Employers’ Accounting for Employee Stock Ownership Plans” (“SOP 93-6”). The Company believes that accounting for its ESOP in accordance with the provisions of SOP 93-6 is preferable as it addresses ESOP issues that were not contemplated in SOP 76-3, including changes to ESOP since its inception, and reflects the fair value of compensation costs in the statement of operations consistent with the preferred method of accounting for other stock-based compensation plans. In accordance with Accounting Principles Board Opinion No. 20, “Accounting Changes”, this change in accounting method has been applied retroactively by restating prior financial statements for all affected periods including the quarters ended March 31, 2003, June 30, 2003 and September 30, 2003. The effect of the change was to increase net income by $5 million and earnings per share by $0.05 in both 2002 and 2001, as well as increase net income by $2 million, $1 million and $1 million and earnings per share by $0.02, $0.01 and $0.01 in the quarters ended March 31, 2003, June 30, 2003 and September 30, 2003, respectively. Retained earnings at January 1, 2001 has been increased by $5 million, net of taxes, unearned compensation increased by $2 million and additional paid-in capital decreased by $7 million, for the retroactive effect of this change in accounting. Additionally, the Company has restated prior period basic and diluted earnings (loss) per share information pursuant to the method prescribed by SOP 93-6, which requires the exclusion of unallocated ESOP shares from the determination of the weighted-average number of shares outstanding. The effect of this change was the exclusion of the following number of shares from the weighted-average number of shares outstanding used to calculate earnings per share: 2.7 million shares for 2003, 3.1 million shares for 2002 and 3.4 million shares for 2001.

     The components of inventories are:

     Inventories valued on the LIFO method were lower than if valued under the average-cost method, which approximates current cost, by $21 million and $20 million at December 31, 2003 and 2002, respectively. The average-cost value of inventories subject to LIFO was $52 and $46 million at December 31, 2003 and 2002, respectively.

     Effective January 1, 2002, the Company adopted SFAS 142. Under SFAS 142, goodwill and intangible assets with indefinite useful lives are not amortized but instead are reviewed for impairment at least annually and written down only in periods in which it is determined that the fair value is less than the recorded value. SFAS 142 also requires the impairment review to be performed on a reporting unit basis. The Company identified the following reporting units: BetzDearborn, Pulp and Paper, Aqualon, FiberVisions and Pinova (formerly Rosin and Terpenes). In connection with the Company’s transitional review, recorded goodwill was determined to be impaired in the BetzDearborn and the FiberVisions reporting units. In the first quarter of 2002, the Company completed its transitional impairment review of identified reporting units and recognized after-tax impairment losses of $262 million in the BetzDearborn reporting unit and $87 million in the FiberVisions reporting unit as a cumulative effect of a change in accounting principle.

27

Hercules Incorporated
Notes to Consolidated Financial Statements

     The impairment charges recognized in the BetzDearborn and FiberVisions reporting units were primarily the result of new and stronger competitors and newer technology, which created significant price erosion and competition. In addition, the BetzDearborn reporting unit was negatively impacted by a failure to achieve integration synergies. SFAS 142 requires the Company to compare a reporting unit’s book value of net assets, including goodwill, to its fair value. In the case of the BetzDearborn reporting unit, fair value was determined primarily by reference to the negotiated selling price. With respect to the Company’ s other reporting units, fair value was estimated using a combination of valuation approaches including the market value and income approaches. In the event that the book value exceeds the fair value, the Company is required to perform a second step to measure the amount of the impairment loss. In the second step, the Company determined the implied value of goodwill by determining the fair value of the assets and liabilities of the BetzDearborn and FiberVisions reporting units. To the extent that the book value of the goodwill exceeded the implied fair value of goodwill for each reporting unit, impairment existed and was recognized.

     In addition, an after-tax impairment loss of $19 million was recognized in the first quarter of 2002 relating to the Company’s equity investment in CP Kelco, which had an impairment under SFAS 142. After recognition of this impairment, the carrying value for the Company’s investment in CP Kelco was zero.

     The following table reflects the effect of the adoption of SFAS 142 on net income (loss) and net earnings (loss) per share as if SFAS 142 had been in effect for the periods presented.

28

Hercules Incorporated
Notes to Consolidated Financial Statements

     Accumulated amortization for goodwill upon adoption of SFAS 142 was $185 million. The following table shows changes in the carrying amount of goodwill for the years ended December 31, 2002 and 2003, by operating segment:

     The following table provides information regarding the Company’s other intangible assets with finite lives:

     Total amortization expense for other intangible assets for the years ended December 31, 2003, 2002 and 2001 was $8 million, $11 million and $26 million, respectively, of which $8 million in 2003 and $9 million in 2002 and 2001, respectively, was included in income from continuing operations. Total goodwill amortization expense for the year ended December 31, 2001 was $50 million, of which $15 million was included in income from continuing operations. Estimated amortization expense is $8 million for 2004 and $7 million per year for 2005 through 2008.

5. Short-term Debt

     A summary of short-term debt follows:

     Bank borrowings represent primarily foreign overdraft facilities and short-term lines of credit, which are generally payable on demand with interest at various rates. Book values of bank borrowings approximate market value because of their short maturity period. At December 31, 2003, Hercules had $17 million of unused short-term lines of credit that may be drawn as needed, with interest at a negotiated spread over lenders’ cost of funds. The weighted-average interest rate on short-term borrowings at December 31, 2002 was 2.67%.

Hercules Incorporated
Notes to Consolidated Financial Statements

     In July 1999, the Company and Hercules Trust II (“Trust II”), a subsidiary trust, completed a $350 million underwritten public offering of 350,000 CRESTS Units. Each CRESTS Unit consists of one preferred security of Trust II and one warrant to purchase 23.4192 shares of the Company’s common stock at an initial exercise price of $1,000 (equivalent to $42.70 per share). The preferred security component of the CRESTS Units was initially valued at $741.46 per unit and the warrant component of the CRESTS Units was initially valued at $258.54 per warrant. The preferred security and warrant components of each CRESTS Unit may be separated and transferred independently. The warrants may be exercised, subject to certain conditions, at any time before March 31, 2029, unless there is a reset and remarketing event. No reset and remarketing event will occur before July 27, 2004, unless all of the Company’s common stock is acquired in a transaction that includes cash for a price above a predetermined level. Trust II used the proceeds from the sale of its preferred securities to purchase junior

subordinated deferrable interest debentures of Hercules. The Company pays interest on the debentures, and Trust II pays distributions on its preferred securities quarterly at an annual rate of 61/2% of the scheduled liquidation amount of $1,000 per debenture and/or preferred security until the scheduled maturity date and redemption date of June 30, 2029, unless there is a reset and remarketing event. The Company guarantees the obligations of Trust II on the preferred securities. Trust II must redeem the preferred securities when the debentures are redeemed or repaid at maturity. As of December 31, 2003, no warrants had been exercised. The Company used the proceeds from the CRESTS Units offering to repay long-term debt. Issuance costs related to the preferred security component of the CRESTS Units are being amortized over the life of the security and costs related to the warrants were charged to additional paid-in capital.

     In May 2003, the FASB issued Statement of Financial Accounting Standards No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity” (“SFAS 150”). SFAS 150 requires certain financial instruments with both debt and equity characteristics to be classified as debt. The statement requires initial and subsequent valuation of this debt at a present or fair market value and was effective July 1, 2003.

     In accordance with SFAS 150, the TOPrS and CRESTS Units constitute mandatorily redeemable financial instruments. The Company guarantees the obligations of Hercules Trust I and Hercules Trust II (the “Trusts”) on the preferred securities. Upon adoption of SFAS 150 on July 1, 2003, the company-obligated preferred securities of subsidiary trusts have been reclassified prospectively from the mezzanine section to the long-term liabilities section of the Consolidated Balance Sheet. Items previously shown separately on the Consolidated Statement of Operations as preferred security distributions of subsidiary trusts are combined with interest and debt expense in the current period in accordance with the requirements of SFAS 150.

     During the fourth quarter of 2003, the Company purchased 46,000 of the CRESTS Units for a total of $34 million, of which $27 million was attributed to the preferred security component and $7 million was attributed to the warrants. The corresponding book value of a similar number of the CRESTS Units junior subordinated deferrable interest debentures was $34 million. Accordingly, the Company recognized a gain of $7 million ($5 million after-tax) in continuing operations. However, the Company has determined that (i) the Trusts are variable interest entities and (ii) the Company is not the primary beneficiary of the Trusts. Accordingly, the Company has de-consolidated the Trusts and recognized an after-tax loss of $5 million as a cumulative effect of a change in accounting principle to defer the above noted gain, effective December 31, 2003, in accordance with the provisions of FASB Interpretation No. 46 (revised December 2003), “Consolidation of Variable Interest Entities” (“FIN 46R”). As a result of the de-consolidation, long-term debt reflects the Company’s obligation to the Trusts for the CRESTS Units junior subordinated deferrable interest debentures and TOPrS junior subordinated deferrable interest debentures. The indenture for the CRESTS Units junior subordinated deferrable interest debentures does not provide the ability for the Company to repay, redeem or defease the CRESTS Units junior subordinated deferrable interest debentures through purchasing the CRESTS Units. Accordingly, at December 31, 2003 the outstanding balance of CRESTS Units junior subordinated deferrable interest debentures has not changed as a result of the Company’s purchase of the CRESTS Units. The $27 million paid to purchase the CRESTS Units preferred security component is reflected as an increase in the Company’s investment in Hercules Trust II, with the corresponding gain on the purchase deferred until Hercules Trust II has been liquidated. The $7 million paid and attributable to the warrants has been recorded as a reduction in additional paid-in-capital.

     Long-term debt maturities are $22 million in 2004, $19 million in 2005, $7 million in 2006, $568 million in 2007, $0 million in 2008 and $732 million thereafter.

7. Consolidation of Variable Interest Entities

     In January 2003, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 46, “Consolidation of Variable Interest Entities” (“FIN 46”), which is an interpretation of Accounting Research Bulletin No. 51, “Consolidated Financial Statements” (“ARB 51”). FIN 46 addresses the application of ARB 51 to variable interest entities (“VIEs”), and generally requires that assets, liabilities and results of the activity of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The provisions of FIN 46 apply on a prospective basis to VIEs created after January 31, 2003 and were to become effective after June 30, 2003 for VIEs that existed prior to January 31, 2003. On October 8, 2003, the FASB deferred the effective date for VIEs that existed prior to January 31, 2003. FASB Staff Position FIN 46-6 (“FSP FIN 46-6”) established the first interim or annual period ending after December 15, 2003 as the new effective date for VIEs that existed prior to January 31, 2003. However, FSP FIN 46-6 permitted early and partial adoption of FIN 46. On December 24, 2003, the FASB issued FASB Interpretation No. 46 (revised December 2003), “Consolidation of Variable Interest Entries” (“FIN 46R”). The Company elected to partially adopt FIN 46 in the quarter ending September 30, 2003 for its VIEs that existed prior to January 31, 2003 (the Company has no VIEs created subsequent to January 31, 2003). The financial statements for the year ended December 31, 2003

reflect the consolidation of two joint venture VIEs, ES FiberVisions Holdings A/S and ES FiberVisions L.P., that were previously accounted for using the equity method of accounting. These entities serve as strategic global marketers of the Company’s bicomponent fibers. As of December 31, 2003, the fair value of the assets in these joint ventures was approximately $7 million and the fair values of the associated liabilities and non-controlling interests were approximately $6 million. There are no assets of the Company that serve as collateral for the VIEs and the creditors of the VIEs have no recourse to the general credit of the Company.
