                          NOTES TO FINANCIAL STATEMENTS


1.   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) makes matching contributions
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
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 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.

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 2% and 3% both at December 31,
2000 and 1999 respectively. 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:

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.

5.   PLAN TRANSFERS

          On June 16, 2000, Hercules' Nitrocellulose business was acquired by
Green Tree Chemical Technologies. Nitrocellulose was manufactured at Hercules'
Parlin, NJ plant location. The Hercules Incorporated Employee Savings Plan was
established specifically for the employees at the Parlin site. Following the
sale, the former employees had the option of keeping their account balances in
the Hercules Employee Savings Plan, withdrawing the funds if retirement
eligible, or electing to rollover their entire account balance(s) into an
Individual Retirement Plan (IRA) or other qualified plan. There were
approximately 315 plan participants with account balances prior to the sale. As
of December 31, 2000, approximately 200 of these participants remained in the
plan.


6.   SUBSEQUENT EVENTS

         After the close of business on January 31, 2001, the Hercules
Incorporated Employee Savings Plan merged into the Hercules Incorporated Savings
and Investment Plan. Pursuant to the merger, 194 participants with assets having
a fair market value of $ 7,345,810 million at the time of the merger, became
part of the Hercules Incorporated Savings & Investment Plan.

         The former Hercules Incorporated Employee Savings Plan participants
underwent changes to their benefits under the Hercules Incorporated Savings &
Investment Plan. In the former plan, participants could make contributions on a
post-tax basis only. The employer match was 2.5% of the first 10% of employee
contributions, and was a participant-directed investment. In the Hercules
Incorporated Savings and Investment Plan, the company makes matching
contributions in the form of Hercules Incorporatied common stock. The former
plan did not allow for participant loans. In the Hercules Incorporated Savings
and Investment Plan, participants can make contributions in 1% increments from 2
% to 15% of base pay on a pre or post-tax basis. Participants are also eligible
for participant loans.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors,
Hercules Incorporated,
Wilmington, Delaware

In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Hercules Incorporated Employee Savings Plan (the "Plan") at December 31,
2000 and December 31, 1999, and the changes in net assets available for benefits
for the year ended December 31, 2000 in conformity with accounting principles
generally accepted in the United States of America. 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 of America, 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 our opinion.
