     INFORMATION CONTAINED HEREIN IS SUBJECT TO COMPLETION OR AMENDMENT. A
     REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS BEEN FILED WITH THE
     SECURITIES AND EXCHANGE COMMISSION. THESE SECURITIES MAY NOT BE SOLD NOR
     MAY OFFERS TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT
     BECOMES EFFECTIVE. THIS PROSPECTUS SHALL NOT CONSTITUTE AN OFFER TO SELL OR
     THE SOLICITATION OF AN OFFER TO BUY NOR SHALL THERE BE ANY SALE OF THESE
     SECURITIES IN ANY STATE IN WHICH SUCH OFFER, SOLICITATION OR SALE WOULD BE
     UNLAWFUL PRIOR TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS
     OF ANY SUCH STATE.


                SUBJECT TO COMPLETION -- DATED DECEMBER 12, 1997

PROSPECTUS

                                 252,600 SHARES

                               [BetzDearborn Logo]


                                  COMMON STOCK

        The 252,600 shares of common stock, par value $.10 per share (the
"Common Stock"), to which this Prospectus relates (the "Shares") are being
offered on behalf and for the account of certain stockholders (the "Selling
Stockholders") of BetzDearborn Inc. (the "Company"). The Company anticipates
that the Shares will be offered for sale until the earlier of (i) the sale of
all of such Shares or (ii) the first anniversary of the issuance of the Shares.
The Company has agreed to pay all expenses of registration in connection with
this offering but will not receive any of the proceeds from the sale of the
Shares being offered hereby. All brokerage commissions and other similar
expenses incurred by the Selling Stockholders will be borne by such Selling
Stockholders. The aggregate proceeds to the Selling Stockholders from the sale
of the Shares will be the purchase price of the Shares sold, less the aggregate
brokerage commissions and underwriters' discounts, if any, and other expenses of
issuance and distribution not borne by the Company. See "Use of Proceeds," "Plan
of Distribution" and "Selling Stockholders."

        The Common Stock is listed on the New York Stock Exchange (the "NYSE")
under the symbol "BTL". On December __, 1997, the last reported sales price for
the Common Stock was $__ per share.

        The offering is currently not being underwritten. However, the Selling
Stockholders, brokers, dealers or underwriters that participate with the Selling
Stockholders in the distribution of the Shares may be deemed "underwriters," as
that term is defined in the Securities Act of 1933, as amended (the "Securities
Act"), and any commissions received by broker-dealers, agents or underwriters
and any profit on the resale of the Shares purchased by them may be deemed to be
underwriting commissions or discounts under the Securities Act. It is
anticipated that all Shares being offered hereby, when sales thereof are made,
will be made in one or more transactions (which may involve one or more block
transactions) through customary brokerage channels, either through brokers
acting as brokers or agents for the sellers, or through dealers or underwriters
acting as principals who may resell the Shares through the NYSE or in privately
negotiated sales, or otherwise, or by a combination of such methods of offering.
Each sale may be made either at market prices prevailing at the time of the
sales or at negotiated prices.

        To the extent required, the specific Shares to be sold, the names of the
Selling Stockholders, the purchase price, the public offering price, the names
of any such agents, dealers or underwriters and any applicable commission or
discount with respect to a particular offer will be set forth in an accompanying
Prospectus Supplement.

            THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY
    THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
               NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR
           ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR
               ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO
                       THE CONTRARY IS A CRIMINAL OFFENSE.

                                   THE COMPANY

        BetzDearborn Inc. is a Pennsylvania corporation with its principal
executive offices located at 4636 Somerton Road, Trevose, Pennsylvania 19053
(telephone 215-355-3300). It also has facilities in 21 U.S. locations, including
11 production plants, and 28 locations outside the U.S., including 19 production

        BetzDearborn Inc. and its subsidiaries (the "Company") are engaged in
the engineered chemical treatment of water, wastewater and process systems
operating in a wide variety of industrial and commercial applications, with
particular emphasis on the chemical, petroleum refining, paper, automotive,

                                 USE OF PROCEEDS

        The Shares of Common Stock being offered hereby are for the account of
the Selling Stockholders. Accordingly, the Company will not receive any of the
proceeds from the sale of the Shares by the Selling Stockholders. See "Selling
Stockholders."

                              SELLING STOCKHOLDERS

        The following table sets forth the name of each of the Selling
Stockholders and the number of Shares that may be offered by each. The number of
Shares that may be actually sold by each of the Selling Stockholders will be
determined by each such Selling Stockholder, and may depend upon a number of
factors, including, among other things, the market price of the Common Stock.
Because each of the Selling Stockholders may offer all, some or none of the
Shares that each holds, and because the offering contemplated by this Prospectus
is currently not being underwritten, no estimate can be given as to the number
of Shares that will be held by each of the Selling Stockholders upon or prior to
termination of this offering. It is anticipated, however, that the Selling
Stockholders will offer all of the Shares for sale. See "Plan of Distribution."
The table below sets forth information as of December __, 1997, concerning the
beneficial ownership of the Shares of each of the Selling Stockholders. All
information as to beneficial ownership has been furnished by each of the Selling
Stockholders.

12,591 Shares (the "escrowed shares"), issued to the Walker Revocable Trust, the
Slater/Battle Family Trust of 1994, the Szeles Family Trust of 1992, and Dale
Walker, were deposited into an escrow account to satisfy certain indemnification
provisions. The Company granted registration rights to the persons receiving the
Shares (including the escrowed shares) and pursuant thereto has registered for
sale in the offering made hereby 252,600 shares of Common Stock. The costs of
this registration (other than brokerage commissions and other similar expenses)
will be paid by the Company. Argo Scientific is in the business of providing
specialty water treatment services. Argo Scientific had revenues of $9,133,230
and $6,053,665 for the year ended February 28, 1997 and the seven-month period
ended September 30, 1997, respectively. It has facilities in the United States
and Scotland which serve North America and Europe. In connection with the Argo
Scientific acquisition, the Company caused Argo Scientific to enter into a
five-year employment agreement with Dale Walker, former President of Argo
Scientific, to serve as Vice President and General Manager of Argo Scientific.
In addition, Lawrence Steneck will remain with Argo Scientific as its Chief
Financial Officer. Mr. Walker and Mr. Durham, as well as the other Selling
Stockholders who placed shares in escrow, have entered into three-year
noncompetition agreements with the Company.

        Other than as set forth in the previous paragraph, none of the parties
to the transactions described therein are affiliates of the Company at this
time.

                          DESCRIPTION OF CAPITAL STOCK

AUTHORIZED AND OUTSTANDING CAPITAL STOCK

        Pursuant to the Restated Articles of Incorporation of the Company, the
authorized capital stock of the Company is 91,000,000 shares, consisting of:

        (a) 1,000,000 shares of Preferred Stock, par value $.10 per share (the
"Preferred Stock"), 500,030 shares of which have been designated as Series A
ESOP Convertible Preferred Stock ("Series A Preferred Stock"); and

        (b) 90,000,000 shares of Common Stock, par value $.10 per share (the
"Common Stock").

        As of November 30, 1997, the Company had outstanding 29,422,829 shares
of Common Stock held by 3,496 shareholders of record, and 475,939 shares of
Series A Preferred Stock held by the Company's Employee Stock Ownership Plan. At
November 30, 1997, there were a total of 8,618,643 shares of Common Stock
reserved for issuance pursuant to the Company's various option, incentive, stock
purchase and other benefit plans, as well as upon conversion of the Series A
Preferred Stock.

        No holder of any class of the Company's capital stock is entitled to
preemptive rights.


                                       7
<PAGE>   9


        In general, the classes of authorized capital stock are afforded
preferences with respect to dividends and liquidation rights in the order listed
above. The Board of Directors of the Company is empowered, without approval of
the shareholders, to cause the Preferred Stock to be issued in one or more
series, with the numbers of shares of each series and the rights, preferences
and limitations of each series to be determined by it. The specific matters that
may be determined by the Board of Directors include the dividend rights,
redemption rights, liquidation preferences, if any, conversion and exchange
rights, retirement and sinking fund provisions and other rights, qualifications,
limitations and restrictions of any wholly unissued series of Preferred Stock
(or of the entire class of Preferred Stock if none of such shares have been
issued), the number of shares constituting such series and the terms and
conditions of the issue thereof. The descriptions set forth below do not purport
to be complete and are qualified in their entirety by reference to (i) the
Restated Articles of Incorporation and, in the case of the Series A Preferred
Stock, the Company's Statement Affecting Class or Series of Shares (the
"Statement Affecting Class"), and (ii) the By-Laws of the Company as currently
in effect (the "By-Laws").

COMMON STOCK

        Subject to the preferential rights of the Series A Preferred Stock and
any preferential rights of any other Preferred Stock created by the Board of
Directors, each outstanding share of Common Stock is entitled to such dividends
as the Board of Directors may declare from time to time out of funds legally
available therefor. Except as hereinafter described, holders of both Common
Stock and Preferred Stock (including the Series A Preferred Stock) are entitled
to one vote for each share of Common Stock or Preferred Stock (including the
Series A Preferred Stock), as applicable, but do not have any right to cumulate
votes in the election of directors. If, however, dividend arrearages on the
Preferred Stock accumulate in amounts specified in the Restated Articles of
Incorporation, holders of the Preferred Stock have the right to elect a
specified number of directors, voting as a class, to the extent specified in the
Restated Articles of Incorporation. In the event of liquidation, dissolution or
winding-up of the Company, holders of Common Stock will be entitled to receive
on a pro rata basis any assets remaining after provision for payment of
creditors and after payment of liquidation preferences to holders of the
Preferred Stock (including the Series A Preferred Stock). The Common Stock is
listed on the New York Stock Exchange, under the symbol "BTL".

        The Common Stock Transfer Agent and Registrar is American Stock Transfer
and Trust Company, New York, New York.

PREFERRED STOCK

        No Preferred Stock is being registered. The following is a brief
description of the Series A Preferred Stock which is convertible into Common
Stock.

        Each outstanding share of the Series A Preferred Stock, is entitled to
cumulative, quarterly cash dividends when, as and if declared by the Board of
Directors, and no dividends may be paid on any other class or series of stock
that ranks on a parity with the Series A Preferred Stock as to dividends unless
dividends on the Series A Preferred Stock are paid concurrently or prior
thereto. The voting rights and liquidation preference of the Series A 


                                       8
<PAGE>   10


Preferred Stock are as described above in "Common Stock." Transfer of shares of
Series A Preferred Stock may be made only to (i) any successor to the trustee of
the Company's Employee Stock Ownership Plan (the "Plan") or (ii) any person, a
transfer to whom would afford the Company a federal income tax deduction under
section 404(k) of the Internal Revenue Code of 1986 ("Code") in the amount of
the dividends paid to such person (each, a "Permitted Transferee").

        Holders of the Series A Preferred Stock may convert any or all of their
shares, at their option, into shares of Common Stock, but the Company has the
right to issue cash in lieu of fractional shares. Upon conversion, the Company
must issue, together with each share of Common Stock, one right to purchase
Common Stock pursuant to a Rights Agreement between the Company and Mellon Bank
(East) N.A. Shares of Series A Preferred Stock are subject to automatic
conversion in the event of transfer to any person other than a Permitted
Transferee. The conversion price of the Series A Preferred Stock is subject to
adjustment in the event of (i) payment of a dividend or other distribution on
the Common Stock in shares of Common Stock, (ii) an increase or decrease in the
number of outstanding shares of Common Stock, (iii) issuance of any right or
warrant to purchase shares of Common Stock to holders of Common Stock as a
dividend or other distribution at a price below fair market value, (iv)
issuance, sale or exchange of shares of Common Stock for a consideration below
fair market value, (v) issuance, sale or exchange of any right or warrant to
purchase or acquire shares of Common Stock, other than any such issuance to
holders of Common Stock as a dividend or other distribution, for consideration
having a fair market value below the "Non-Dilutive Amount" as defined in the
Statement Affecting Class or (vi) an "Extraordinary Distribution" as defined in
the Statement Affecting Class.

        The Series A Preferred Stock is redeemable, in whole or in part, at the
option of the Company for the amount payable upon liquidation. The Series A
Preferred Stock is also redeemable at the option of the holder when and to the
extent necessary for such holder to (i) provide for distributions required to be
made to participants under the Plan, (ii) make any payments of principal,
interest or premium due and payable under any indebtedness incurred by the
holder for the benefit of the Plan or (iii) meet the diversification
requirements of section 404(a)(28) of the Code. The Company may pay the
redemption price in cash or, except for a redemption pursuant to clause (iii),
in shares of Common Stock, or a combination thereof; when the Company pays in
shares, it must issue, with each such share, one right to purchase Common Stock
pursuant to the Rights Agreement.

        In the event of a merger or similar business combination in which the
Company's Common Stock is exchanged solely for, or converted into, "qualified
employer securities" as defined in the Statement Affecting Class, the Series A
Preferred Stock will either (i) become preferred stock of the resulting entity
(with the same rights and preferences that it had before the transaction) or
(ii) be converted into or exchanged for the securities or cash receivable by a
holder of the number of shares of Common Stock into which the shares of Series A
Preferred Stock were convertible immediately prior to the transaction. A similar
provision for conversion applies to the Series A Preferred Stock in the event of
a merger or similar combination in which the Company's Common Stock is exchanged
for, or converted into, cash or securities that are not 


                                       9
<PAGE>   11

"qualified employer securities." If the Company enters into an agreement
providing for the latter type of merger or combination, the holders of the
Series A Preferred Stock may elect to redeem their shares.

PROVISIONS OF RESTATED ARTICLES OF INCORPORATION AND BY-LAWS

        Certain provisions of the Restated Articles of Incorporation and By-Laws
of the Company may delay or make more difficult unsolicited acquisitions or
changes of control of the Company. It is believed that such provisions will
enable the Company to develop its business in a manner that will foster its
long-term growth without disruption caused by the threat of a takeover not
deemed by its Board of Directors to be in the best interests of the Company and
its shareholders. Such provisions may also have the effect of making it more
difficult for third parties to cause the replacement of the current management
of the Company without the concurrence of the Board of Directors. These
provisions include, among others, (i) the availability of capital stock for
issuance from time to time at the discretion of the Board of Directors (see
"Authorized and Outstanding Capital Stock"), (ii) classified Board of Directors,
(iii) the ability of the Board of Directors to increase the size of the board
and to appoint directors to fill newly created directorships, (iv) supermajority
voting requirements and (v) business combinations with interested shareholders.
The descriptions set forth herein of such provisions do not purport to be
complete and are qualified in their entirety by reference to the Restated
Articles of Incorporation and the By-Laws.

Classified Board of Directors

        The Company's By-Laws provide that the Board of Directors be divided
into three classes as nearly equal in number as possible, whose three-year terms
of office expire at different times in annual succession. A classified board
makes it more difficult for shareholders to change a majority of the directors.

Number of Directors; Filling of Vacancies

        The By-Laws of the Company limit the total number of directors to 13 and
provide that newly-created directorships resulting from any increase in the
authorized number of directors or any vacancy shall be filled by a vote of a
majority of directors then in office. Accordingly, the Board of Directors of the
Company may be able to prevent any shareholder from obtaining majority
representation on the Board of Directors by increasing the size of the board and
filling the newly created directorships with its own nominees.

Supermajority Vote Requirements

        The Company's By-Laws require that any proposal to change the number,
classification or term of office of directors must receive the affirmative vote
of at least 75% of all shares outstanding as of the record date for the meeting
at which such proposal is to be voted on, as well as the affirmative vote of at
least 75% of all shares outstanding.



                                       10
<PAGE>   12

        The Company's Restated Articles of Incorporation require, in regard to
the vote of the shareholders for approval of any plan of merger or
consolidation, for the sale of all or substantially all the Company's assets or
for the adoption of any amendment to the section of the Articles of
Incorporation setting forth this requirement, not only the approval of the
holders of a majority of the outstanding Common Stock and Preferred Stock
(voting together), but also the approval of at least two-thirds of the shares
(regardless of class) represented in person or by proxy at the particular
meeting.

Business Combinations with Interested Shareholders

        The Company's Restated Articles of Incorporation generally prohibit
business combinations with interested shareholders unless certain terms and
conditions are satisfied, which terms and conditions are substantially similar
to those set forth in the "business combination" provisions of the Pennsylvania
Business Corporation Law described below. See "Description of Capital Stock -
Pennsylvania Business Corporation Law."

PENNSYLVANIA BUSINESS CORPORATION LAW

        Certain provisions of the Pennsylvania Business Corporation Law of 1988
(the "PBCL") may have the effect of deterring, delaying or preventing an attempt
by a third party to acquire control of the Company.

        The "control transactions" provisions in Sections 2541 through 2548 of
the PBCL require that any person or group that acquires at least 20% of the
voting power of a corporation (a "Controlling Person or Group") give notice of
such acquisition to the other shareholders of the corporation. The corporation's
shareholders are entitled to demand payment of the fair value of their shares
from the Controlling Person or Group. The definition of "Controlling Person or
Group" excludes from calculation of the 20% requirement, inter alia, (i) shares
held continuously since January 1983, (ii) shares acquired by gift, inheritance
or bequest from a person who had acquired the shares prior to January 1983,
(iii) shares acquired pursuant to a stock split, dividend, reclassification or
similar recapitalization, (iv) shares acquired by an underwriter pursuant to a
firm commitment underwriting registered under the Securities Act of 1933, as
amended, and (v) shares held by agents, brokers, nominees, trustees and other
similar record holders for beneficial owners either who do not possess 20% of
the voting power of the corporation or who otherwise satisfy one of the
foregoing exceptions.

        The "business combination" provisions in Sections 2551 through 2556 of
the PBCL prohibit the Company from engaging in any business combination (which
is defined broadly to include mergers, consolidations, share exchanges,
divisions and sales or other dispositions of assets having a value in excess of
10% or more of the assets, market value or earning power or net income of the
corporation) with an "interested shareholder" or an affiliate thereof unless (A)
the business combination or the acquisition of shares in which a person becomes
an interested shareholder is approved by the Board of Directors before the
shareholder becomes an "interested shareholder," (B) the interested shareholder
owns 80% of the corporation's outstanding voting shares and the business
combination satisfies certain "fair price" criteria and is approved by the
holders of a majority of the remaining shares, (C) the business combination is
approved by all of 


                                       11
<PAGE>   13


the holders of the Company's Common Stock, (D) the holders of a majority of the
voting shares (excluding those held by the interested shareholder) approve the
business combination at a meeting held no earlier than five years after the
interested shareholder's share acquisition date or (E) the business combination
is approved at a shareholders' meeting called for such purpose no earlier than
five years after the interested shareholder's share acquisition date that
satisfies certain "fair price" criteria. An "interested shareholder" is any
beneficial owner of 20% or more of the voting shares of a corporation, or an
affiliate of the corporation who was at any time within the five-year period
prior to the date in question a beneficial owner of 20% or more of the voting
shares of the corporation, but does not include shareholders who were interested
shareholders prior to the date of the adoption of these provisions by the
Company.

        The "control share" provisions in Sections 2561 through 2568 of the PBCL
deprive any of a corporation's "Control shares" of their voting rights unless
the holders of a majority of the voting power of the corporation vote to restore
such rights in two separate votes as follows: (i) all voting shares of the
corporation and (ii) all shares of the corporation other than those held by the
Company's executive officers or directors who are also officers, certain
employee stock plans and the person acquiring the Control shares. Control shares
are those voting shares the acquisition of voting power over which would confer
on the person acquiring them, when added to all voting power of the person over
other voting shares of the corporation, the ability to cast in an election of
directors, for the first time, a percentage of the voting power of the
corporation that falls within any of the following ranges: (i) at least 20% but
less than 33 1/3%; (ii) at least 33 1/3% but less than 50%; or (iii) at least
50%. In calculating such percentage, the following shares are excluded: (i)
voting shares beneficially owned continuously since January 1988~; (ii) voting
shares beneficially owned that were acquired by gift, inheritance or bequest
from a person who had beneficially owned the shares prior to January 1988; and
(iii) shares acquired pursuant to a stock split, dividend or other similar
distribution.

        The "disgorgement" provisions in Sections 2571 through 2576 of the PBCL
permit a corporation to recover from "controlling persons" any profit realized
by such controlling persons from the disposition of any equity security of the
corporation if the equity securities (i) were sold within 18 months after such
persons became "controlling persons" and (ii) had been acquired by the
controlling persons within 24 months prior, or 18 months subsequent to, the date
on which the controlling persons became "controlling persons." A controlling
person is anyone who has, offers to acquire, or publicly discloses the intention
to acquire, 20% of the voting power of the corporation, or anyone who publicly
discloses the intention to acquire control of a corporation through any means.
The provisions provide a safe harbor for shareholders who would be deemed
"controlling persons" by reason of voting or giving a proxy or consent, under
certain circumstances evidencing the lack of any intention on the part of such
shareholders to change or influence control of the corporation.

        In addition to the above, the PBCL expressly permits directors of a
corporation to consider the interests of constituencies other than shareholders,
such as employees, suppliers, customers and the community, in discharging their
duties, provides that they need not, in considering the best interests of the
corporation, consider any particular constituency's interests (including the
interests of shareholders) as the dominant or controlling interest, and provides
that 

                                       12
<PAGE>   14


directors do not violate their fiduciary duty by relying on shareholders' rights
plans or other anti-takeover provisions of the PBCL.

RIGHTS PLAN

        The Company has a Shareholder Rights Plan ("Rights Plan") to protect
shareholder interests in the face of a threatened hostile acquisition. Under the
terms of the Rights Plan, each holder of shares of Common Stock owns rights to
purchase that number of shares of Common Stock equal to the number of such
shares held, upon the occurrence of certain events designed to gain control of
the Company without offering fair value to the Company's shareholders.

INDEMNIFICATION

        Third Party Actions. The Company's By-Laws provide that the Company
shall indemnify any director or officer of the Company who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Company) by reason of the fact
that he or she is or was an authorized representative of the Company which means
a director, officer, employee or agent of the Company, or a person who is or was
serving at the request of the Company as a director, officer, employee or agent
of another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him or her in connection with
such action, suit or proceeding if he or she acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of the
Company, and, with respect to any criminal action or proceeding, has no
reasonable cause to believe his or her conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction , or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interest of the
Company, and, with respect to any criminal action or proceeding, had reasonable
cause to believe that his conduct was unlawful.

        Derivative Actions. The Company's By-Laws also provide that the Company
shall indemnify any director or officer of the Company who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the Company to procure a judgment in its favor by
reason of the fact that he or she is or was an authorized representative of the
Company, against expenses (including attorneys' fees) actually and reasonably
incurred by him or her in connection with the defense or settlement of such
action or suit if he or she acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to, the best interests of the
Company and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his or her duty to the
Company unless and only to the extent that a court shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to such
expenses which the court shall deem proper.


                                       13
<PAGE>   15


        Expense of Litigation. Expenses incurred by any director, officer,
employee or agent in defending a civil or criminal action, suit or proceeding
may be paid by the Company in advance of final disposition of such action, suit
or proceeding upon receipt of an undertaking by or on behalf of such person to
repay such amount if it shall ultimately be determined such person is not
entitled to be indemnified by the Company.

        By-Law Provisions Not Exclusive. The provisions of the By-Laws are not
exclusive of any other rights to which a person seeing indemnification or
advancement of expenses may be entitled under any other provision of the
By-Laws, or any agreement, vote of shareholders, vote of directors or otherwise
both as to acts or failure to act of such person in his or her official
capacity and as to acts or failure to act in another capacity while holding
office. The Company shall have the fullest authority to indemnify any such
director, officer, employee or agent permitted under the laws of the
Commonwealth of Pennsylvania; provided, however, no indemnification shall be
made in any case where the act or failure to act giving rise to the claim for
indemnification is finally determined by a court to have constituted willful
misconduct or recklessness.

LIMITATION OF LIABILITY

        Pursuant to the Company's By-Laws, no director, including a director who
is also an officer, of the Company shall be personally liable for monetary
damages for any action taken, or any failure to take any action in his or her
capacity as a director, including his or her duties as a member of any committee
of the Board of Directors upon which he or she may serve unless: (i) the
director has breached or failed to perform his or her duties as a director in
good faith, in a manner he or she reasonably believed to be in the best interest
of the Company and with such care, including reasonable inquiry, skill and
diligence, as a person of ordinary prudence would use under similar
circumstances; and (ii) such breach or failure to perform his or her duties
constitutes self-dealing, willful misconduct or recklessness. Absent a breach by
a director of his or her duty as a fiduciary to the Company, lack of good faith,
or self-dealing, the acts of or failure to act by a director in his or her
capacity as a director shall be presumed to be in the best interest of the
Company.

                              PLAN OF DISTRIBUTION

        The Company will receive no proceeds from the sale of the Shares by the
Selling Stockholders. The Shares may be sold from time to time to purchasers
directly by the Selling Stockholders. Alternatively, the Selling Stockholders
may sell the Shares in one or more transactions (which may involve one or more
block transactions) on the New York Stock Exchange, in privately negotiated
transactions or otherwise or in a combination of such transactions; each sale
may be made either at market prices prevailing at the time of such sale or at
negotiated prices; some or all of the Shares may be sold through broker-dealers
acting as brokers or agents on behalf of the Selling Stockholders or to
broker-dealers acting as principals for resale by such dealers; and in
connection with such sales, such broker-dealers may receive compensation in the
form of commissions, discounts or fees from the Selling Stockholders and/or the
purchasers of such shares for whom they may act as broker or agent. It is
anticipated that the Selling Stockholders will offer all of the Shares for sale.
All expenses of registration 


                                       14
<PAGE>   16

incurred in connection with this offering are being borne by the Company, but
all brokerage commissions and other similar expenses incurred by the Selling
Stockholders will be borne by the Selling Stockholders.

        At the time a particular offer of Shares is made, to the extent
required, a supplement to this Prospectus (the "Prospectus Supplement") will be
distributed that will identify and set forth the aggregate amount of Shares
being offered and the terms of the offering, including the name or names of any
underwriters, dealers or agents, the purchase price paid by any underwriter for
Shares purchased from Selling Stockholders, any commissions, discounts or
concessions allowed or reallowed or paid to dealers, including the proposed
selling price to the public.

        Each Selling Stockholder and any dealer acting in connection with the
offering of any of the Shares or any broker executing or selling orders on
behalf of any of the Selling Stockholders may be deemed to be an "underwriter"
within the meaning of the Securities Act, in which event any profit on the sale
of any or all of the Shares and any commissions, discounts or concessions
received by any such dealers or brokers may be deemed to be underwriting
commissions and discounts under the Securities Act. Any dealer or broker
participating in any distribution of the Shares may be required to deliver a
copy of this Prospectus, including a Prospectus Supplement, if any, to any
person who purchases any of the Shares from or through such dealer or broker.

        Any person engaged in a distribution of the Shares, including brokers,
dealers and Selling Stockholders, must comply with the trading restrictions
imposed by Regulation M promulgated under the Exchange Act.

        In order to comply with certain states' securities laws, if applicable,
the shares will be sold in such jurisdictions only through registered or
licensed brokers or dealers. The Shares will not be registered or qualified for
sale in any state in reliance of the exemption for securities listed on the NYSE
provided in Section 18 of the Securities Act.

                                  LEGAL MATTERS

        The validity of the Common Stock offered hereby will be passed upon for
the Company by Linda R. Hansen, Esq., Vice President, Secretary and General
Counsel of the Company.

Item 15.      Indemnification of Directors and Officers.

        The sections of the Prospectus entitled "Description of Capital Stock --
Indemnification" and "-- Limitation of Liability" are incorporated herein by
reference.

        Sections 1741 through 1750 of the Pennsylvania Business Corporation Law
provide broad authority for indemnification of officers and directors.

        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that, in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Securities Act and is therefore
unenforceable.

        The Registrant maintains directors' and officers' liability insurance
that covers the directors and officers of the Registrant.

Item 16.      Exhibits.

reference in this Registration Statement. Where such filing is made by
incorporation by reference to a previously filed report or registration

Item 17.       Undertakings.

        (a) Rule 415 Offering. The undersigned hereby undertakes:

               (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

                   (A) to include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                   (B) to reflect in the Prospectus any facts or events arising
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the Registration
Statement; and

                   (C) to include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement or
any material change to such information in the Registration Statement.

               (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the official bona
fide offer thereof.

               (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

        (b) Filings incorporating subsequent Exchange Act documents by
reference. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in this 

                                      II-2
<PAGE>   20


Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

        (h) Request for acceleration of effective date. Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the Registration
pursuant to the Company's By-Laws or otherwise, the Registrant has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

        (i) Rule 430. The undersigned registrant hereby undertakes that:

            (1) For purposes of determining any liability under the Securities
Act, the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) under the
Securities Act shall be deemed to be part of this Registration Statement as of
the time it was declared effective.

            (2) For purposes of determining any liability under the Securities
Act, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Board of Directors
BetzDearborn Inc.

               Re:    Registration Statement on Form S-3

Ladies and Gentlemen:

        As General Counsel of BetzDearborn Inc. (the "Company") I have assisted
in the preparation and filing with the Securities and Exchange Commission under
the Securities Act of 1933, as amended, of a Registration Statement on Form S-3
(the "Registration Statement") relating to the sale by certain Selling
Stockholders of 252,600 shares of Common Stock described in the Prospectus in
the Registration Statement ("Prospectus").

        In so acting, I have examined and relied upon the original or copies,
certified or otherwise identified to my satisfaction, of such corporate records,
documents, certificates, and other instruments, and such factual information
otherwise supplied to me as in my judgment are necessary or appropriate to
enable me to render the opinion expressed below.

        On the basis of and subject to the foregoing, I am of the opinion the
Common Stock, when sold pursuant to the Registration Statement and Prospectus,
will, under the laws of the Commonwealth of Pennsylvania, be duly and validly
issued, fully paid, and non-assessable.

        I consent to the use of this opinion as an exhibit to the Registration
Statement and to the use of my name under the headings "Legal Matters" in the
Preliminary Prospectus forming a part of the Registration Statement.

                                                   Very truly yours,

                                                   /s/ LINDA R. HANSEN
                                                   ------------------------

                         CONSENT OF INDEPENDENT AUDITORS

We consent to the reference to our firm under the caption "Experts" in the
Registration Statement (Form S-3 No. 333- ) and related Prospectus of
BetzDearborn Inc. for the registration of 252,600 shares of its Common Stock and
to the incorporation by reference therein of our reports (a) dated February 11,
1997, with respect to the consolidated financial statements incorporated by
reference in its Annual Report (Form 10-K) for the year ended December 31, 1996
and (b) dated March 24, 1997, with respect to the financial statement schedule
included in its Annual Report (Form 10-K) for the year ended December 31, 1996,
both filed with the Securities and Exchange Commission.
