DESCRIPTION OF PLAN AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Hercules Incorporated Employee Savings Plan (the Plan) is a defined-contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Upon hire, employees are immediately eligible to participate in the Plan and obtain immediate, nonforfeitable (vested) rights to the full market value of their account. At time of enrollment in the Plan, a participant, by giving written notice to the Trustee, shall direct the investment of his monthly savings in any of the Plan's investment media, or a combination thereof, providing his monthly savings in any one medium selected is not less than 20% of the total amount saved and is stated in 5% increments. 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 participants' 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 assets of the Plan are commingled for investment purposes in the Hercules Incorporated Master Savings Trust (the Trust) with the assets of the Hercules Incorporated Savings and Investment Plan. The assets of the Trust are held by Bankers Trust Company (Trustee). The Plan's investment in the Trust is based upon the fair value of net assets in the Trust and the Plan's relative interest in the Trust. The investments in the accompanying statements of net assets available for Plan benefits represent the Plan's share of the investments in the Trust, which was 2.53% and 2.32% at December 31, 1997 and 1996, respectively. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make significant 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. 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 accrued interest, which is equivalent to contract value, which approximates fair 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 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. 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 up to age 70 in which the distribution is requested. 4 6 The Plan presents in the statement of changes in net assets available for benefits its allocated share of the Trust's investment activities that include the net appreciation (depreciation) in fair value of its investments (under the caption Change in Market Value), which consists of the realized gains or losses and the change in unrealized appreciation (depreciation) on those investments. 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. In the event of Plan termination, participants will become 100 percent vested in their accounts. 2. INVESTMENT PROGRAM The following investment media are available under the Employee Savings Plan: 1. Hercules Incorporated Common Stock. 2. A Blended Interest Rate Savings Fund, wherein savings so directed are deposited with various major insurance companies, who guarantee the payment of principal. For 1997 and 1996, the blended yield of these contracts was approximately 6.4% and 6.1%, respectively. 3. Equity Fund. This Fund is made up of substantially all the stocks that make up the Standard and Poor's 500 Index in such a mix as to track as closely as possible the movement of the Index. 4. Fidelity Magellan Fund is a Long-Term Capital Appreciation Fund, which invests in common stocks, and securities convertible to common stock, issued by companies operating in the U.S. and abroad as well as foreign companies. 5. Frank Russell Equity Index Fund sells high long-term returns by investing in common stocks of the largest companies in the U.S. stock market. 6. SEI International Equity Fund seeks to provide aggressive long-term growth from investments in foreign stocks and diversification in domestic stock portfolios. 7. SEI Small Cap. Growth Fund invests in stocks of smaller companies that are in an early stage or transition point in their development. 8. SEI Diversified Moderate Growth Fund invests in U.S. and international stocks and provides a limited level of current income by investing in bonds. The Company contribution, as defined in the Plan, is equal to 25% of the participants' contribution. There were 378 participants at December 31, 1997 who participated in one or more of the four investment media. At December 31, 1997 the number of participants selecting each of the investment media for their contributions was as follows: Hercules Incorporated Common Stock ....................... 342 Equity Fund............................................... 64 Blended Interest Rate Savings Fund ....................... 199 Fidelity Magellan Fund.................................... 86 Frank Russell Equity Index Fund........................... 9 SEI Diversified Moderate Growth Fund...................... 1 SEI International Equity Fund............................. 1 SEI Small Cap. Growth Fund................................ 4 5 7 3. INTEREST IN HERCULES INCORPORATED MASTER SAVINGS TRUST The Plan's allocated share of the Savings Trust's net assets is based upon the total of each individual Plan's interest in investments of the Trust. The allocated interest of the net assets of each fund in the Trust at December 31 was as follows: 1997 1996 ---- ---- Hercules Incorporated Common Stock Fund........................ 0.9% 0.8% Equity Fund.................................................... 1.4% 1.1% Blended Interest Rate Savings Fund............................. 4.4% 3.5% Fidelity Magellan Fund......................................... 4.2% 3.9% Frank Russell Equity Index Fund................................ 1.1% 0% SEI Small Cap. Growth Fund..................................... 0.8% 0% Loan Fund...................................................... 0% 0% SEI Diversified Moderate Growth Fund........................... 0% 0% SEI International Equity Fund.................................. 0% 0% 4. INTERPLAN TRANSFERS Interplan transfers represent transfers to acquiring Company plans, the Hercules Incorporated Savings and Investment Plan and rollovers of new employees' distributions from defined contribution Plans. 5. TAX STATUS The United States Treasury Department advised on June 21, 1995 that the Plan as amended through January 1, 1995 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 currently being operated in compliance with the applicable provisions of the Internal Revenue Code. 6. INVESTMENTS The Plan's allocated interest in investments in the Trust that represent five percent or more of net assets available for benefits at December 31, 1997 or 1996 are as follows: 1997 1996 ---- ---- Hercules Incorporated Common Stock $ 654,845 $ 599,692 Equity Fund $ 886,024 $ 534,665 Fidelity Magellan Fund $1,362,345 $1,106,394 Group Annuity Contract with Peoples Life Insurance Company (#BDA 00002TR) $1,056,404 $ 799,930 Group Annuity Contract with Metropolitan Life Insurance Company (#12833) -- $ 667,065 GIC Prudential (#GA 8083) $1,185,706 $ 896,254 Hartford Life Contract (#GA 10226) $ 494,418 $ 397,444 Group Annuity Contract with Transamerica Life (#76589) $ 844,109 $ 640,992 6 8 7.

These financial statements are the responsibility of the Plan's administrators. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of Hercules Incorporated Employee Savings Plan as of December 31, 1997 and 1996, and the changes in net assets available for benefits for the year ended December 31, 1997 in conformity with generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The Fund Information in the accompanying statements of net assets available for benefits of the Hercules Incorporated Employee Savings Plan and the related statement of changes in net assets available for benefits is presented for purposes of additional analysis rather than to present the net assets available for plan benefits and changes in net assets available for plan benefits of each fund. The Fund Information has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.
