                          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.

      On June 16, 2000, Hercules' Nitrocellulose business was acquired by Green
      Tree Chemical Technologies. Nitrocellulose was manufactured at Hercules'
      Parlin, NJ plant location. The 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 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 January 31, 2001, approximately 200 of these
      participants remained in the plan.

      After the close of business on January 31, 2001, the Plan merged with and
      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 at the time of the merger, became part of the Hercules
      Incorporated Savings and Investment Plan.

      The Plan's participants underwent changes to their benefits under the
      Hercules Incorporated Savings and Investment Plan. For additional
      information regarding these changes, participants should refer to the plan
      document for the Hercules Incorporated Savings and Investment Plan.

      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 statements
      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 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. 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. 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.



                                       5

      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 period. 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 end of period, 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.

      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
      Bankers Trust Company (Trustee) holds the assets of the Trust. The Plan's
      share of the net assets in the Trust was approximately zero and 2% at
      January 31, 2001 and December 31, 2000, 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. Investment income relating to the
      Trust is applied to the units or shares that individual plan participants
      hold in unitized or net asset value funds, respectively. Net appreciation
      (depreciation) is allocated to the individual plans based on the relative
      percentage of each plan's holdings in the trust. Also, administrative
      expenses associated with the Trust are allocated entirely to the Hercules
      Incorporated Savings and Investment Plan.

      The following table presents the fair values of investments for the Trust:



                                           January 31, 2001      December 31, 2000

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.

                        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 January 31,
2001 and December 31, 2000, and the changes in net assets available for benefits
for the month ended January 31, 2001, 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.

As discussed in Note 1, effective January 31, 2001, the Plan was merged with and
into the Hercules Incorporated Savings and Investment Plan.
