                         NOTES TO FINANCIAL STATEMENTS



1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         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 fair value. The market value
of the Equity Fund, the Balanced Asset Fund, the Government Bond Fund and the
Fidelity Magellan Fund 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. The liability
for such withdrawals is reflected in the financial statements on the Optional
Valuation Date.

         The Plan presents in the statement of income and changes in plan
equity 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.

         The unrealized appreciation (depreciation) for all investments at
December 31, 1994, December 31, 1993, December 31, 1992, and January 1, 1992
was $73,619,161, $87,056,699, $35,861,479, and $22,458,111, respectively.

2.  INVESTMENT PROGRAM

         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 following, 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.

         During May 1993, the Money Market Fund was eliminated and a U.S.
Government Bond Fund, a Balanced Asset Management Fund and a Long-Term Capital
Appreciation (Fidelity Magellan) Fund were added as investment media under the
Plan.  Participants with balances in the Money Market Fund were provided the
option to transfer their balances to other investment funds or have their
balances automatically transferred to the new U.S. Government Bond Fund.

         The following investment medium are available under the Savings and
Investment 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 1994, the blended yield of these contracts
         was approximately 7.1%.

    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.   U.S. Government Bond Fund, which invests in U.S. Treasury and Agency
         issues and fully insured savings bank deposits.

    5.   Balanced Asset Management Fund, which invests in a managed portfolio
         of stocks, bonds and money market instruments.

    6.   Fidelity Magellan Fund is a Long-Term Capital Appreciation (Fidelity)
         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.

         The Company contribution, as defined in the Plan, is equal to 50% of
that portion of the participants' contribution which does not exceed 6% of
earnings or base pay and must be invested in common stock of Hercules
Incorporated.

         There were 9,049 participants at December 31, 1994 who participated in
one or more of the six investment media.  At December 31, 1994 the number of
participants selecting each of the investment media for their contributions was
as follows:

3.  INTERPLAN TRANSFERS

         Interplan transfers represent transfers from acquired company plans
and the Hercules Incorporated Employee Savings Plan and rollovers of new
employees' distributions from defined contribution plans.

         Effective January 1, 1993, the net assets of the Capital Accumulation
Plan (approximately $31 MM) of the Aqualon Company (a wholly-owned subsidiary
of Hercules Incorporated) were transferred to the Hercules Incorporated Savings
and Investment Plan.  Participant's benefits under the plan were substantially
unaffected by the transfer of net assets.

4.  TAX STATUS

         The United States Treasury Department advised on February 17, 1987,
that the Plan as amended through January 1, 1985 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 Federal Income Tax status of the employee is covered under the
caption "Federal Tax Aspects" of the Summary Plan Description dated November 1,
1990 and supplemented by periodic benefit updates.

5.  INVESTMENTS

         Investments that represent five percent or more of Plan Equity at
December 31, 1994 or 1993 are as follows:



                                                                                              1994                    1993

6.  SUBSEQUENT EVENT

         On March 15, 1995 Hercules completed the sale of its Aerospace
business to Alliant Techsystems Inc. (Alliant).  The sale agreement provided
for a transfer of fund assets (approximately $200 million) and assumption of
fund liabilities to Alliant as of April 1, 1995.

                       REPORT OF INDEPENDENT ACCOUNTANTS

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

    We have audited the accompanying statements of assets, liabilities and plan
equity with fund information of Hercules Incorporated Savings and Investment
Plan as of December 31, 1994 and 1993, and the related statements of income and
changes in plan equity with fund information for each of the three years in the
period ended December 31, 1994.  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 financial position of Hercules Incorporated
Savings and Investment Plan as of December 31, 1994 and 1993, and its income
and changes in plan equity for each of the three years in the period ended
December 31, 1994 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 assets, liabilities, and plan equity of the Hercules
Incorporated Savings and Investment Plan and the related statements of income
and changes in plan equity is presented for purposes of additional analysis
rather than to present the financial position and income and changes in plan
equity 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.
