DESCRIPTION OF PLAN The following description of the Hercules Incorporated Savings and Investments 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, substantially all domestic Hercules Incorporated ("Hercules" or the "Company") 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 15% of their annual wages on either a pre- or post-tax basis, or a combination thereof. The Company contributes in the form of Hercules Incorporated common stock, 50% of the first 6% of the annual wages that an employee contributes to the Plan. Participants shall direct the investment of their monthly savings in any of the Plan's investment options, 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 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 Plan includes an employee loan provision authorizing participants to borrow a minimum of $1,000 up to a maximum, equal to the lesser of $50,000 or 50% of their vested balances in the Plan. The loans are executed by promissory notes and have a minimum term of 12 months and a maximum term of 60 months, except for qualified residential loans, which have a maximum term of 120 months. The loans bear an interest rate equal to the average rate charged by selected major banks to prime customers for secured loans. The loans are repaid over the term in monthly installments of principal and interest by payroll deduction. A participant also has the right to repay the loan in full at any time without penalty. On April 24, 2002, the Board of Directors of Hercules approved the merging of the BetzDearborn Inc. Employee Stock Ownership and 401(k) Plan (the "BetzDearborn Plan") into the Hercules Incorporated Savings and Investment Plan, effective March 1, 2002 (See Note 6). 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. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 Hercules Blended Interest Fund is carried at cost plus investment earnings less withdrawals, which is equivalent to contract value. The market value for funds managed by The Vanguard Group are 5 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. 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. 3. INVESTMENTS At the beginning of 2002, the assets of the Plan were held in the Hercules Incorporated Master Savings Trust. However, on April 29, 2002, the Board of Directors of the Company approved the appointment of The Vanguard Group (the "Trustee") as both the trustee and record keeper for the Plan, effective July 1, 2002. At December 31, 2002, the assets of the Plan are held by the Trustee.

TAX STATUS On March 18, 2003, the United States Treasury Department advised the Company that the Plan as amended through January 28, 2002, 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, to include, among other things, the merger of the BetzDearborn Plan (see Note 6). However, the Plan administrator and the Plan's tax counsel believe that the Plan is designed and currently being operated in compliance with the applicable requirements of the Internal Revenue Code. 6. MERGER OF BETZDEARBORN PLAN On April 28, 2002, pursuant to a Stock and Asset Purchase Agreement executed February 12, 2002 (the "Agreement"), the Company sold its BetzDearborn Water Treatment Business to GE Specialty Materials ("GESM"), a unit of General Electric Company (the "Water Treatment Business sale"). In accordance with the terms of the Agreement, the Company was required to take certain actions to facilitate the Water Treatment Business sale, as summarized below. On April 24, 2002, the Board of Directors of Hercules approved the merging of the BetzDearborn Plan into the Plan, effective March 1, 2002. In addition, the BetzDearborn Plan Trust was transferred from BetzDearborn Inc. to Hercules. Approximately 2,475 participants with net assets having a fair market value of $131,824 thousand at the time of the plan transfer, became part of the Plan. The following schedule summarizes the March 1, 2002 assets and liabilities of the BetzDearborn Plan which merged into the Plan: 8 (Dollars in thousands) March 1, 2002 ---------------------- Investments $ 177,926 Hercules stock ESOP - Unallocated 40,359 Interest receivable 1,931 ------------ Total assets 220,216 ------------ Loan payable - Prudential 75,461 Loan payable - Hercules 11,000 Interest payable 1,931 ------------ Total liabilities 88,392 ------------ Transfer from the BetzDearborn Plan 131,824 Transfers from other plans 5 ------------ Total transfers from other plans $ 131,829 ============ Effective with the closing of the Water Treatment Business sale, the Board of Directors amended the BetzDearborn Plan to facilitate BetzDearborn Plan participants who are Water Treatment Business employees to make direct account rollovers to the GE 401(k) Plan, including: (i) full and immediate vesting of all account balances coincident with the closing of the Water Treatment Business sale, (ii) permitting transfers to and from Hercules stock accounts without restraint, (iii) allowing retention of the right to have Hercules stock accounts distributed in the form of stock certificates, and (iv) allowing the retention of the account balances and loans under the Plan. Of the $52,406 thousand transferred to other plans, $4,174 thousand was transferred to General Electric Company benefit plans. The remaining transfers were to IRA's and other qualified benefit plans. At December 31, 2001, prior to its merger into the Plan, the BetzDearborn Plan, had long-term debt with third parties of $75 million ("ESOP credit facility"), which was guaranteed by the Company, as well as $11 million of debt with the Company, pursuant to a loan agreement entered into with the Company in December 2001. This loan agreement permitted the Plan to borrow up to $86 million from the Company. On April 29, 2002, the Company used a portion of the proceeds from the Water Treatment Business sale to fully prepay the existing ESOP credit facility. Concurrent with this prepayment, the Plan borrowed the additional $75 million from the Company, pursuant to the aforementioned loan agreement. The $75 million promissory note requires quarterly payments of $250 thousand and the $11 million note requires annual payments of $200 thousand. Any remaining principal balance on either note is payable December 31, 2020. Outstanding borrowings under the promissory notes are $76 million at December 31, 2002. 7. RELATED PARTY TRANSACTIONS Certain Plan investments are shares of mutual funds managed by the Trustee, therefore, these transactions qualify as party-in-interest transactions. 9 HERCULES INCORPORATED SAVINGS AND INVESTMENT PLAN SCHEDULE I SUPPLEMENTAL SCHEDULE H, PART IV, ITEM 4(i) ASSETS HELD FOR INVESTMENT PURPOSES DECEMBER 31, 2002 (Dollars in thousands) Identity of Issue Investment Type Cost Current Value - ------------------------------------------------------------------------------------------------------------- * Vanguard 500 Index Fund Registered Investment Company $ 40,854 $ 37,076 * Vanguard Explorer Fund Registered Investment Company 5,451 4,799 * Vanguard Extended Market Index Fund Registered Investment Company 1,832 1,852 * Vanguard Growth & Income Fund Registered Investment Company 21,550 19,146 * Vanguard International Growth Fund Registered Investment Company 5,661 5,297 * Vanguard LifeStrategy Conservative Growth Fund Registered Investment Company 2,487 2,397 * Vanguard LifeStrategy Growth Fund Registered Investment Company 1,404 1,383 * Vanguard LifeStrategy Income Fund Registered Investment Company 1,357 1,365 * Vanguard LifeStrategy Moderate Growth Fund Registered Investment Company 4,102 3,955 * Vanguard PRIMECAP Fund Registered Investment Company 28,997 28,848 * Vanguard Small-Cap Value Index Fund Registered Investment Company 659 643 * Vanguard Total Bond Market Index Fund Registered Investment Company 15,040 15,310 * Vanguard Windsor II Fund Registered Investment Company 16,766 16,360 * Hercules Common Stock Fund Company Stock Fund 216,340 73,203 * Loan Fund 6.50%-11.50% 4,852 4,852 * Hercules Blended Interest Fund Unallocated Insurance Contract 91,177 91,177 ------------------------ Total assets held for investment purposes $ 458,529 $ 307,663 ======================== * Indicates party-in-interest to the Plan 10 HERCULES INCORPORATED SAVINGS AND INVESTMENT PLAN SCHEDULE II SUPPLEMENTAL SCHEDULE H, PART IV, ITEM 4(j) REPORTABLE TRANSACTIONS DECEMBER 31, 2002 (Dollars in thousands) Current Value of Identity of Party Historical Cost Asset on Historical Gain Involved Description of Asset Purchase Price Selling Price of Asset Transaction Date (Loss) - ----------------- ---------------------- -------------- ------------- --------------- ---------------- --------------- The Vanguard Group Hercules Blended $ 100,041 $ 100,041 Interest Fund The Vanguard Group Hercules Blended $ 8,864 $ 8,864 8,864 $ - Interest Fund The Vanguard Group Hercules Common 59,280 59,280 Stock Fund The Vanguard Group Hercules Common 2,285 4,151 2,285 (1,866) Stock Fund 11 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors Hercules Incorporated Wilmington, Delaware We have audited the accompanying statement of net assets available for benefits of Hercules Incorporated Savings and Investment Plan as of December 31, 2002, and the related statement of changes in net assets available for benefits for the year then ended.
