DESCRIPTION OF PLAN AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The following description of the Hercules Incorporated Employee Savings Plan (the Plan) provides only general information. The Plan is a defined contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. Upon hire, certain represented employees are immediately eligible to participate in the Plan and obtain immediate, non-forfeitable (vested) rights to the full market value of their account. At time of enrollment in the Plan, participants may elect to contribute up to 10% of their annual wages on a post-tax basis. Hercules Incorporated (the Company) contributes up to 25% of the first 10% of the annual wages that an employee contributes to the Plan. The participant shall direct the investment of his or her monthly savings in 5% increments and the employer match in any of the Plan's investment media, with the exception of the Hercules Incorporated stock fund, or a combination thereof. The Plan provides for various investment options in any combination of stocks, bonds, fixed income securities, mutual funds, and other investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participant's account balances and the amounts reported in the statement of net assets available for benefits and the statement of changes in net assets available for benefits. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and changes therein, and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The financial statements of the Plan are prepared under the accrual method of accounting. Investments in the Plan are carried at fair value. The fair value of the common stock of Hercules Incorporated is based upon the price at which the stock closed on the New York Stock Exchange on the last business day of the year. The Blended Interest Rate Savings Fund is carried at cost plus investment earnings less withdrawals, which is equivalent to contract value. The market value of the Equity Fund, the Fidelity Magellan Fund, the Frank Russell Equity Index Fund, and the SEI group of funds is valued at the net asset value of the shares held by the Plan at year end, which is based on the fair value of the underlying securities held by the fund. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis and dividends are recorded on the ex-dividend date. The Plan presents in the statement of changes in net assets available for benefits its allocated share of the Trust's investment income that includes the net appreciation (depreciation) in fair value of its investments, which consists of the realized gains or losses and the change in unrealized appreciation (depreciation) on those investments. Withdrawals are recorded upon distribution. The Plan provides that participants who retire from the Company may elect, upon retirement, an Optional Valuation Date (OVD) for determining their final withdrawal. The OVD is the last business day of any month following retirement, in which the distribution is requested. Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. 6 2. INVESTMENTS IN MASTER TRUST The assets of the Plan are held in the Hercules Incorporated Master Savings Trust (the Trust) along with the assets of the Hercules Incorporated Savings and Investment Plan. Bankers Trust Company (Trustee) holds the assets of the Trust. The fair value of the Plan's interest in the Trust is based on the beginning of year value of the Plan's interest in the Trust plus contributions and allocated investment income less actual distributions. The Plan's share of the net assets in the Trust was approximately 3% both at December 31, 1999 and 1998. However, 100% of the Trust's Loan Fund balance is allocated to the Hercules Incorporated Savings & Investment Plan. Recordkeeping for the Plan is performed by MetLife's Defined Contribution Group. The following table presents the fair values of investments for the Trust: December 31, 1999 1998 ------------ ------------ Hercules Incorporated Common Stock ............. $ 55,786,379 $ 50,333,052 Mutual Funds ................................... 178,488,853 157,476,226 Blended Interest Rate Fund ..................... 109,620,622 112,915,032 Loan Fund ...................................... 8,092,771 8,654,993 ------------ ------------ Total: .................................... $351,988,625 $329,379,303 ============ ============ Investment income for the trust for the year ended December 31, 1999 is as follows: Net appreciation in fair value of investments: Hercules Incorporated Common Stock ........ $ 1,607,455 Mutual Funds .............................. 27,879,518 ------------ 29,486,973 Interest .................................. 7,641,318 Dividends ................................. 8,091,845 ------------ Total ..................... $ 45,220,136 ============ 3. TAX STATUS The United States Treasury Department advised on October 29, 1997 that the Plan as amended through February 1, 1996 is a qualified trust under Section 401(a) of the Internal Revenue Code and is therefore exempt from Federal income taxes under provisions of Section 501(a) of the code. The Plan has been amended since receiving the determination letter. However, the Plan administrator believes that the Plan is designed and currently being operated in compliance with the applicable provisions of the Internal Revenue Code. 4.

These financial statements are the responsibility of the Plan's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States, which 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 the opinion expressed above. /s/ PricewaterhouseCoopers LLP Philadelphia, Pennsylvania 19103 June 26, 2000 9 SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the trustees (or other persons who administer the Plan) have duly caused this annual report to be signed by the undersigned hereunto duly authorized.
