                              INFORMATION REQUIRED
                          IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents filed by Ecolab Inc. (the "Company"  or the
"Registrant") (File No.1- 9328) with the Securities and Exchange Commission (the
"Commission") are incorporated by reference in this Registration Statement:  (1)
Annual Report on Form 10-K for the year ended December 31, 1995; (2) Quarterly
Reports on Form 10-Q for the quarters ended March 31, June 30 and September 30,
1996; (3) Current Report on Form 8-K dated February 24, 1996; (4) Current Report
on Form 8-K dated December 16, 1996; (5) all other reports filed by the Company
pursuant to Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), since December 31, 1995; (6) the description of
the Company's Common Stock, Preferred Stock and Rights contained in its
Registration Statement on Form 8-A, including any amendments or reports filed
for the purpose of updating such description.

         All documents filed by the Company with the Commission pursuant to
Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of this
Registration Statement and prior to the filing of a post-effective amendment
which indicates that all shares of Common Stock offered pursuant to this
Registration Statement have been sold or that de-registers all shares of Common
Stock then remaining unsold, shall be deemed to be incorporated by reference in
this Registration Statement and to be a part hereof from the date of filing of
such documents.

         The consolidated financial statements and related financial statement
schedule of the Company, which are included or incorporated by reference in the
Company's Annual Report on Form 10-K for the year ended December 31, 1995, and
incorporated by reference in this Registration Statement, have been audited by
Coopers & Lybrand L.L.P., independent accountants, for the periods indicated in
such firm's reports thereon.  The consolidated financial statements and
financial statement schedule audited by Coopers & Lybrand L.L.P. have been
incorporated herein by reference in reliance on such firm's reports given upon
their authority as experts in accounting and auditing.  To the extent that
Coopers & Lybrand L.L.P. examines and reports on the financial statements and
financial statement schedules of the Company issued at future dates, and
consents to the use of their reports thereon, such financial statements and
financial statement schedules will also be incorporated by reference in the
Registration Statement in reliance upon their reports and said authority.

         With respect to unaudited interim financial information incorporated by
reference in this Registration Statement, the independent accountants have
reported that they have applied limited procedures in accordance with
professional standards for reviews of such information.  However, their separate
reports, incorporated by reference herein, state that they did not audit and
they do not express an opinion on that interim financial information.
Accordingly, the degree of reliance on their reports on such information should
be restricted in light of the limited nature of the review procedures applied.
The accountants are not subject to the liability provisions of Section 11 of the
Securities Act of 1933 (the "Securities Act") for their reports on the unaudited
interim financial information because each such report is not a "report"  or a
"part" of the Registration Statement prepared or certified by the accountants
within the meaning of Sections 7 and 11 of the Securities Act.

         In addition, the combined financial statements and financial statement
schedule of the


                                        2
<PAGE>


Henkel-Ecolab Joint Venture, which are included in the Company's Annual Report
on Form 10-K for the year ended December 31, 1995, and incorporated by reference
in this Registration Statement, have been audited by KPMG Deutsche
Treuhand-Gesellschaft Aktiengesellschaft, independent accountants, for the
periods indicated in such firm's reports thereon.  The combined financial
statements and financial statement schedule audited by KPMG Deutsche
Treuhand-Gesellschaft Aktiengesellschaft have been incorporated herein by
reference in reliance on such firm's reports given upon their authority as
experts in accounting and auditing.  To the extent that KPMG Deutsche
Treuhand-Gesellschaft Aktiengesellschaft examines and reports on the financial
statements and the financial statement schedules of the Henkel-Ecolab Joint
Venture issued at future dates, and consents to the use of their reports
thereon, such financial statements and financial statement schedules will also
be incorporated by reference in the Registration Statement in reliance upon
their reports and said authority.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable - the Company's Common Stock and Rights to be offered
pursuant to this Registration Statement have been registered under Section 12 of
the Exchange Act as described in Item 3 of this Part II.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Subsection (a) of Section 145 of the General Corporation Law of
Delaware ("DGCL") empowers a corporation to indemnify any person 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 corporation), by
reason of the fact that such person is or was a director, officer, employee or
agent of the corporation or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding if such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the corporation, and with respect to any criminal action or
proceeding, had no reasonable cause to believe such person's conduct was
unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify 
any person who was or is a party or threatened to be made a party to any 
threatened, pending or completed action or suit by or in the right of the 
corporation to procure a judgment in its favor by reason of the fact that 
such person acted in any of the capacities set forth above, against expenses 
actually and reasonably incurred by such person in connection with the 
defense or settlement of such action or suit if such person acted under 
similar standards, except that no indemnification may be made in respect of 
any claim, issue or matter as to which such person shall have been adjudged 
to be liable to the corporation unless and only to the extent that the Court 
of Chancery or the court in which such action or suit was brought shall 
determine that, despite the adjudication of liability, such person is fairly 
and reasonably entitled to indemnity for such expenses which the court shall 
deem proper.

         Section 145 further provides that, to the extent a director or officer
of a corporation has been successful in the defense of any action, suit or
proceeding referred to in subsections (a) and (b) or in the


                                        3
<PAGE>


defense of any claim, issue or matter therein, such person shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred in
connection therewith; that indemnification provided for by Section 145 shall not
be deemed exclusive of any other rights to which the indemnified party may be
entitled; and that the scope of indemnification extends to directors, officers,
employees or agents of a constituent corporation absorbed in a consolidation or
merger and persons serving in that capacity at the request of the constituent
corporation for another.  Section 145 also empowers the corporation to purchase
and maintain insurance on behalf of a director or officer of the corporation
against any liability asserted against or incurred by such person in any such
capacity or arising out of such person's status as such, whether or not the
corporation would have the power to indemnify such person against such
liabilities under Section 145, including liabilities under the Securities Act.

         Article V of the Company's By-Laws provides for indemnification of the
Company's officers and directors to the full extent allowed by Delaware law.

         In addition, Article IV of the Company's Restated Certificate of
Incorporation provides that the Company's directors do not have personal
liability to the Company or its stockholders for monetary damages for any breach
of their fiduciary duty as directors, except (i) for a breach of the duty of
loyalty, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violation of the law, (iii) for willful or
negligent violations of certain provisions under the DGCL imposing certain
requirements with respect to stock repurchases, redemptions and dividends, or
(iv) for any transaction from which the director derived an improper personal
benefit.  Subject to these exceptions, under Article IV, directors do not have
any personal liability to the Company or its stockholders for any violation of
their fiduciary duty.

         The Company has directors and officers liability insurance which
protects each director or officer from certain claims and suits, including
stockholder derivative suits, even where the director may be determined to not
be entitled to indemnification under the DGCL and claims and suits arising under
the Securities Act.  The policy may also afford coverage under circumstances
where the facts do not justify a finding that the director or officer acted in
good faith and in a manner that was in or not opposed to the best interests of
the Company.

         The Company has entered into indemnification agreements with each of
its directors (the "Indemnification Agreements").  The Indemnification
Agreements provide for the prompt indemnification "to the fullest extent
permitted by law " and for the prompt advancement of expenses, including
attorneys' fees and other costs, expenses and obligations paid or incurred in
connection with investigating, defending, being a witness or participating in
(including on appeal) any threatened, pending or completed action, suit or
proceeding related to the fact that such director is or was a director, officer,
employee, trustee, agent or fiduciary of the Company or is or was serving at the
request of the Company as a director, officer, employee, trustee, agent or
fiduciary of another corporation, partnership, joint venture, employee benefit
plan trust or other enterprise, or by reason of anything done or not done by a
director in any such capacity.  The Indemnification Agreements further provide
that the Company has the burden of proving that a director is not entitled to
indemnification in any particular case.

         The foregoing represents a summary of the general effect of the DGCL,
the Company's By-Laws and Restated Certificate of Incorporation, the Company's
directors and officers liability insurance coverage and the Indemnification
Agreements for purposes of general description only.

ITEM 9.  UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

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

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

               (ii) 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.  Notwithstanding the foregoing,  any increase or
                    decrease in volume of securities offered (if the total
                    dollar value of securities offered would not exceed that
                    which was registered) and any  deviation from the low or
                    high end of the estimated maximum offering range may be
                    reflected in the form of prospectus filed with the
                    Commission pursuant to Rule 424(b) under the Securities Act
                    of 1933 if, in the aggregate, the changes in volume and
                    price represent no more than a 20% change in the maximum
                    aggregate offering price set forth in the "Calculation of
                    Registration Fee" table in the effective registration
                    statement;


                                        5
<PAGE>


              (iii) 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;

                    PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not
               apply if the information required to be included in a
               post-effective amendment by those paragraphs is contained in
               periodic reports filed with or furnished to the Commission by the
               Registrant pursuant to Section 13 or Section 15(d) of the
               Securities Exchange Act of 1934 that are incorporated by
               reference 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 initial bona fide offering
               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.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
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.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant, 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 of 1933 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 Act and
will be governed by the final adjudication of such issue.

                      RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                                   ECOLAB INC.

                           (Originally incorporated as
                          Economics Laboratory, Inc. on
                               February 18, 1924)

                                    ARTICLE I

The name of the Corporation is ECOLAB INC.

                                   ARTICLE II

The purposes of the Corporation are to engage in any lawful act or activity for
which corporations may be organized under the General Corporation Law of
Delaware, and without limiting the foregoing, to hold shares of the capital
stock of other corporations and to engage in services of all kinds, and produce,
manufacture, develop, construct, transport, buy, hold, sell and generally deal
in products, materials and property, both tangible and intangible.

                                   ARTICLE III

The total number of shares of all classes of capital stock which the Corporation
shall have authority to issue is one hundred fifteen million (115,000,000)
consisting of one hundred million (100,000,000) shares of Common Stock of the
par value of One Dollar ($1.00) per share and fifteen million (15,000,000)
shares of Preferred Stock without par value.  The number of authorized shares of
any class of capital stock may be increased or decreased by the affirmative vote
of the holders of a majority of capital stock of the Corporation entitled to
vote.

The Board of Directors of the Corporation is granted full and complete authority
to fix by resolution or resolutions the designation, and the powers, preferences
and rights of the Preferred Stock and any series thereof, and the
qualifications, limitations or restrictions on such powers, preferences and
rights.

                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

     A series of Preferred Stock of the Corporation is hereby created and the
     designation, amount thereof and the working powers, preferences and
     relative, participating, optional and other special rights of the shares of
     such series, and the qualifications, limitations or restrictions thereof
     are as follows:

          Section 1.  DESIGNATION AND AMOUNT.  The shares of such series shall
     be designated as "Series A Junior Participating Preferred Stock" and the
     number of shares constituting such series shall be 500,000.

          Section 2.  DIVIDENDS AND DISTRIBUTIONS.

          (A) Subject to the prior and superior rights of the holders of any
     shares of any series of Preferred Stock, if any, issued from time to time
     ranking prior and superior to the shares of Series A Junior Participating
     Preferred Stock with respect to dividends, the holders of shares of Series
     A Junior Participating Preferred Stock shall be entitled to receive, when,
     as and if declared by the Board of Directors out of funds legally available
     for the purpose, quarterly dividends payable in cash on the fifteenth day
     of February, May, August and November in each year (each such date being
     referred to herein as a "Quarterly Dividend Payment Date"), commencing on
     the first Quarterly Dividend Payment Date after the first issuance of a
     share or fraction of a share of Series A Junior Participating Preferred
     Stock, in an amount per share (rounded to the nearest cent) equal to the
     greater of (a) $26 or (b) subject to the provision for adjustment
     hereinafter set forth, 100 times the aggregate per share amount of all cash
     dividends, and 100 times the aggregate per share amount (payable in kind)
     of all noncash dividends or other distributions other than a dividend
     payable in shares of Common Stock



<PAGE>


     or a subdivision of the outstanding shares of Common Stock (by
     reclassification or otherwise), declared on the Common Stock, par value
     $1.00 per share, of the Corporation (the "Common Stock") since the
     immediately preceding Quarterly Dividend Payment Date, or, with respect to
     the first Quarterly Dividend Payment Date, since the first issuance of any
     share or fraction of a share of Series A Junior Participating Preferred
     Stock.   In the event the Corporation shall at any time after February 14,
     1986 (the "Rights Declaration Date") (i) declare any dividend on Common
     Stock payable in shares of Common Stock, (ii) subdivide the outstanding
     Common Stock, or (iii) combine the outstanding Common Stock into a smaller
     number of shares, then in each such case the amount to which holders of
     shares of Series A Junior Participating Preferred Stock were entitled
     immediately prior to such event under clause (b) of the preceding sentence
     shall be adjusted by multiplying such amount by a fraction the numerator of
     which is the number of shares of Common Stock outstanding immediately after
     such event and the denominator of which is the number of shares of Common
     Stock that were outstanding immediately prior to such event.

          (B)  The Corporation shall declare a dividend or distribution on the
     Series A Junior Participating Preferred Stock as provided in paragraph (A)
     above immediately after it declares a dividend or distribution on the
     Common Stock (other than a dividend payable in shares of Common Stock);
     provided that, in the event no dividend or distribution shall have been
     declared on the Common Stock during the period between any Quarterly
     Dividend Payment Date and the next subsequent Quarterly Dividend Payment
     Date, a dividend of $26 per share as such amount may be adjusted pursuant
     to the last sentence of the preceding paragraph on the Series A Junior
     Participating Preferred Stock shall nevertheless be payable on such
     subsequent Quarterly Dividend Payment Date.

          (C)  Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Junior Participating Preferred Stock from the Quarterly
     Dividend Payment Date next preceding the date of issue of such shares of
     Series A Junior Participating Preferred Stock, unless the date of issue of
     such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Junior Participating
     Preferred Stock entitled to receive a quarterly dividend and before such
     Quarterly Dividend Payment Date, in either of which events such dividends
     shall begin to accrue and be cumulative from such Quarterly Dividend
     Payment Date.  Accrued but unpaid dividends shall not bear interest.
     Dividends paid on the shares of Series A Junior Participating Preferred
     Stock in an amount less than the total amount of such dividends at the time
     accrued and payable on such shares shall be allocated pro rata on a share-
     by-share basis among all such shares at the time outstanding.  The Board of
     Directors may fix a record date for the determination of holders of shares
     of Series A Junior Participating Preferred Stock entitled to receive
     payment of a dividend or distribution declared thereon, which record date
     shall be no more than 60 days prior to the date fixed for the payment
     thereof.

          Section 3.  VOTING RIGHTS.  The holders of shares of Series A Junior
     Participating Preferred Stock shall have the following voting rights:

          (A)  Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Junior Participating Preferred Stock shall entitle
     the holder thereof to 100 votes on all matters submitted to a vote of the
     stockholders of the Corporation.  In the event the Corporation shall at any
     time after the Rights Declaration Date (i) declare any dividend on Common
     Stock payable in shares of Common Stock, (ii) subdivide the outstanding
     Common Stock, or (iii) combine the outstanding Common Stock into a smaller
     number of shares, then in each such case the number of votes per share to
     which holders of shares of Series A Junior Participating Preferred Stock
     were entitled immediately prior to such event shall be adjusted by
     multiplying such number by a fraction the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.


                                        2
<PAGE>
          (B)  Except as otherwise provided herein or by law, the holders of
     shares of Series A Junior Participating Preferred Stock and the holders of
     shares of Common Stock shall vote together as one class on all matters
     submitted to a vote of stockholders of the Corporation.

          (C) (i)  If at any time dividends on any Series A Junior Participating
          Preferred Stock shall be in arrears in an amount equal to six (6)
          quarterly dividends thereon, the occurrence of such contingency shall
          mark the beginning of a period (herein called a "default period")
          which shall extend until such time when all accrued and unpaid
          dividends for all previous quarterly dividend periods and for the
          current quarterly dividend period on all shares of Series A Junior
          Participating Preferred Stock then outstanding shall have been
          declared and paid or set apart for payment.  During each default
          period, all holders of Preferred Stock (including holders of the
          Series A Junior Participating Preferred Stock) with dividends in
          arrears in an amount equal to six (6) quarterly dividends thereon,
          voting as a class, irrespective of series, shall have the right to
          elect two (2) Directors.

               (ii)  During any default period, such voting right of the holders
          of Series A Junior Participating Preferred Stock may be exercised
          initially at a special meeting called pursuant to subparagraph (iii)
          of this Section 3(C) or at any annual meeting of stockholders, and
          thereafter at annual meetings of stockholders, provided that neither
          such voting right nor the right of the holders of any other series of
          Preferred Stock, if any, to increase, in certain cases, the authorized
          number of Directors shall be exercised unless the holders of ten
          percent (10%) in number of shares of Preferred Stock outstanding shall
          be present in person or by proxy.  The absence of a quorum of the
          holders of Common Stock shall not affect the exercise by the holders
          of Preferred Stock of such voting right.  At any meeting at which the
          holders of Preferred Stock shall exercise such voting right initially
          during an existing default period, they shall have the right, voting
          as a class, to elect Directors to fill such vacancies, if any, in the
          Board of Directors as may then exist up to two (2) Directors or, if
          such right is exercised at an annual meeting, to elect two (2)
          Directors.  If the number which may be so elected at any special
          meeting does not amount to the required number, the holders of the
          Preferred Stock shall have the right to make such increase in the
          number of Directors as shall be necessary to permit the election by
          them of the required number.  After the holders of the Preferred Stock
          shall have exercised their right to elect Directors in any default
          period and during the continuance of such period, the number of
          Directors shall not be increased or decreased except by vote of the
          holders of Preferred Stock as herein provided pursuant to the rights
          of any equity securities ranking senior to or PARI PASSU with the
          Series A Junior Participating Preferred Stock.

               (iii)  Unless the holders of Preferred Stock shall, during an
          existing default period, have previously exercised their right to
          elect Directors, the Board of Directors may order, or any stockholder
          or stockholders owning in the aggregate not less than ten percent
          (10%) of the total number of shares of Preferred Stock outstanding,
          irrespective of series, may request the calling of a special meeting
          of the holders of Preferred Stock, which meeting shall thereupon be
          called by the President, a Vice-President or the Secretary of the
          Corporation.  Notice of such meeting and of any annual meeting at
          which holders of Preferred Stock are entitled to vote pursuant to this
          paragraph (C)(iii) shall be given to each holder of record of
          Preferred Stock by mailing a copy of such notice to him at his last
          address as the same appears on the books of the Corporation.  Such
          meeting shall be called for a time not earlier than 20 days and not
          later than 60 days after such order or request or in default of the
          calling of such meeting within 60 days after such order or request,
          such meeting may be called on similar notice by any stockholder or
          stockholders owning in the aggregate not less than ten percent (10%)
          of the total number of shares of Preferred Stock outstanding.
          Notwithstanding the provisions of this paragraph (C)(iii), no such
          special meeting shall be called during the period within 60 days
          immediately preceding the date fixed for the next annual meeting of
          the stockholders.

               (iv)  In any default period, the holders of Common Stock, and
          other classes of stock of the Corporation if applicable, shall
          continue to be entitled to elect the whole number of Directors until
          the

                                        3
<PAGE>
          holders of Preferred Stock shall have exercised their right to elect
          two (2) Directors voting as a class, after the exercise of which right
          (x) the Directors so elected by the holders of Preferred Stock shall
          continue in office until their successors shall have been elected by
          such holders or until the expiration of the default period, and (y)
          any vacancy in the Board of Directors may (except as provided in
          paragraph (C)(ii) of this Section 3) be filled by vote of a majority
          of the remaining Directors theretofore elected by the holders of the
          class of stock which elected the Director whose office shall have
          become vacant.  References in this paragraph (C) to Directors elected
          by the holders of a particular class of stock shall include Directors
          elected by such Directors to fill vacancies as provided in clause (y)
          of the foregoing sentence.

               (v)  Immediately upon the expiration of a default period, (x) the
          right of the holders of Preferred Stock as a class to elect Directors
          shall cease, (y) the term of any Directors elected by the holders of
          Preferred Stock as a class shall terminate, and (z) the number of
          Directors shall be such number as may be provided for in the
          certificate of incorporation or by-laws irrespective of any increase
          made pursuant to the provisions of paragraph (C)(ii) of this Section 3
          (such number being subject, however, to change thereafter in any
          manner provided by law or in the certificate of incorporation or by-
          laws).  Any vacancies in the Board of Directors effected by the
          provisions of clauses (y) and (z) in the preceding sentence may be
          filled by a majority of the remaining Directors.

          (D) Except as set forth herein, holders of Series A Junior
     Participating Preferred Stock shall have no special voting rights and their
     consent shall not be required (except to the extent they are entitled to
     vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

          Section 4.  CERTAIN RESTRICTIONS.

          (A)  Whenever quarterly dividends or other dividends or distributions
     payable on the Series A Junior Participating Preferred Stock as provided in
     Section 2 are in arrears, thereafter and until all accrued and unpaid
     dividends and distributions, whether or not declared, on shares of Series A
     Junior Participating Preferred Stock outstanding shall have been paid in
     full, the Corporation shall not

               (i)  declare or pay dividends on, make any other distributions
          on, or redeem or purchase or otherwise acquire for consideration any
          shares of stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Junior
          Participating Preferred Stock;

               (ii)  declare or pay dividends on or make any other distributions
          on any shares of stock ranking on a parity (either as to dividends or
          upon liquidation, dissolution or winding up) with the Series A Junior
          Participating Preferred Stock, except dividends paid ratably on the
          Series A Junior Participating Preferred Stock and all such parity
          stock on which dividends are payable or in arrears in proportion to
          the total amounts to which the holders of all such shares are then
          entitled;

               (iii)  redeem or purchase or otherwise acquire for consideration
          shares of any stock ranking on a parity (either as to dividends or
          upon liquidation, dissolution or winding up) with the Series A Junior
          Participating Preferred Stock, provided that the Corporation may at
          any time redeem, purchase or otherwise acquire shares of any such
          parity stock in exchange for shares of any stock of the Corporation
          ranking junior (either as to dividends or upon dissolution,
          liquidation or winding up) to the Series A Junior Participating
          Preferred Stock;

               (iv)  purchase or otherwise acquire for consideration any shares
          of Series A Junior Participating Preferred Stock, or any shares of
          stock ranking on a parity with the Series A Junior Participating
          Preferred Stock, except in accordance with a purchase offer made in
          writing or by publication (as determined by the Board of Directors) to
          all holders of such shares upon such terms as the Board of Directors,
          after consideration of the respective annual dividend rates and other
          relative rights and

                                        4
<PAGE>
          preferences of the respective series and classes, shall determine in
          good faith will result in fair and equitable treatment among the
          respective series or classes.

          (B)  The Corporation shall not permit any subsidiary of the
     Corporation to purchase or otherwise acquire for consideration any shares
     of stock of the Corporation unless the Corporation could, under paragraph
     (A) of this Section 4, purchase or otherwise acquire such shares at such
     time and in such manner.

          Section 5.  REACQUIRED SHARES.  Any shares of Series A Junior
     Participating Preferred Stock purchased or otherwise acquired by the
     Corporation in any manner whatsoever shall be retired and cancelled
     promptly after the acquisition thereof.  All such shares shall upon their
     cancellation become authorized but unissued shares of Preferred Stock and
     may be reissued as part of a new series of Preferred Stock to be created by
     resolution or resolutions of the Board of Directors, subject to the
     conditions and restrictions on issuance set forth herein.

          Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.

          (A)  Upon any liquidation (voluntary or otherwise), dissolution or
     winding up of the Corporation, no distribution shall be made to the holders
     of shares of stock ranking junior (either as to dividends or upon
     liquidation, dissolution or winding up) to the Series A Junior
     Participating Preferred Stock unless, prior thereto, the holders of shares
     of Series A Junior Participating Preferred Stock shall have received $100
     per share, plus an amount equal to accrued and unpaid dividends and
     distributions thereon, whether or not declared, to the date of such payment
     (the "Series A Liquidation Preference").  Following the payment of the full
     amount of the Series A Liquidation Preference, no additional distributions
     shall be made to the holders of shares of Series A Junior Participating
     Preferred Stock unless, prior thereto, the holders of shares of Common
     Stock shall have received an amount per share (the "Common Adjustment")
     equal to the quotient obtained by dividing (i) the Series A Liquidation
     Preference by (ii) 100 (as appropriately adjusted as set forth in
     subparagraph (C) below to reflect such events as stock splits, stock
     dividends and recapitalizations with respect to the Common Stock) (such
     number in clause (ii), the "Adjustment Number").  Following the payment of
     the full amount of the Series A Liquidation Preference and the Common
     Adjustment in respect of all outstanding shares of Series A Junior
     Participating Preferred Stock and Common Stock, respectively, holders of
     Series A Junior Participating Preferred Stock and holders of shares of
     Common Stock shall receive their ratable and proportionate share of the
     remaining assets to be distributed in the ratio of the Adjustment Number to
     1 with respect to such Preferred Stock and Common Stock, on a per share
     basis, respectively.

          (B)  In the event, however, that there are not sufficient assets
     available to permit payment in full of the Series A Liquidation Preference
     and the liquidation preferences of all other series of preferred stock, if
     any, which rank on a parity with the Series A Junior Participating
     Preferred Stock, then such remaining assets shall be distributed ratably to
     the holders of such parity shares in proportion to their respective
     liquidation preferences.  In the event, however, that there are not
     sufficient assets available to permit payment in full of the Common
     Adjustment, then such remaining assets shall be distributed ratably to the
     holders of Common Stock.

          (C)  In the event the Corporation shall at any time after the Rights
     Declaration Date (i) declare any dividend on Common Stock payable in shares
     of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
     combine the outstanding Common Stock into a smaller number of shares, then
     in each such case the Adjustment Number in effect immediately prior to such
     event shall be adjusted by multiplying such Adjustment Number by a fraction
     the numerator of which is the number of shares of Common Stock outstanding
     immediately after such event and the denominator of which is the number of
     shares of Common Stock that were outstanding immediately prior to such
     event.

          Section 7.  CONSOLIDATION, MERGER, ETC.  In case the Corporation shall
     enter into any consolidation, merger, combination or other transaction in
     which the shares of Common Stock are exchanged for or changed into other
     stock or securities, cash and/or any other property, then in any such case
     the shares of Series A

                                        5

     Junior Participating Preferred Stock shall at the same time be similarly
     exchanged or changed in an amount per share (subject to the provisions for
     adjustment hereinafter set forth) equal to 100 times the aggregate amount
     of stock, securities, cash and/or any other property (payable in kind), as
     the case may be, into which or for which each share of Common Stock is
     changed or exchanged.  In the event the Corporation shall at any time after
     the Rights Declaration Date (i) declare any dividend on Common Stock
     payable in shares of Common Stock, (ii) subdivide the outstanding Common
     Stock, or (iii) combine the outstanding Common Stock into a smaller number
     of shares, then in each such case the amount set forth in the preceding
     sentence with respect to the exchange or change of shares of Series A
     Junior Participating Preferred Stock shall be adjusted by multiplying such
     amount by a fraction the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event.

          Section 8.  NO REDEMPTION.  The shares of Series A Junior
     Participating Preferred Stock shall not be redeemable.

          Section 9.  RANKING.  The Series A Junior Participating Preferred
     Stock shall rank junior to all other series of the Corporation's Preferred
     Stock which may be issued from time to time as to the payment of dividends
     and the distribution of assets, unless the terms of any such series shall
     provide otherwise.

          Section 10.  AMENDMENT.  The Restated Certificate of Incorporation of
     the Corporation shall not be further amended in any manner which would
     materially alter or change the powers, preferences or special rights of the
     Series A Junior Participating Preferred Stock so as to affect them
     adversely without the affirmative vote of the holders of a majority or more
     of the outstanding shares of Series A Junior Participating Preferred Stock,
     voting separately as a class.

          Section 11.  FRACTIONAL SHARES.  Series A Junior Participating
     Preferred Stock may be issued in fractions of a share which shall entitle
     the holder, in proportion to such holder's fractional shares, to exercise
     voting rights, receive dividends, participate in distributions and to have
     the benefit of all other rights of holders of Series A Junior Participating
     Preferred Stock.

No stockholder shall have any preemptive right to subscribe to an additional
issue of capital stock or to any security convertible into such capital stock.

                                   ARTICLE IV

The business and affairs of the Corporation shall be managed by or under the
direction of a Board of Directors.  Except to the extent prohibited by law, the
Board of Directors shall have the right (which, to the extent exercised, shall
be exclusive) to establish the rights, powers, duties, rules and procedures (a)
that from time to time shall govern the Board of Directors and each of its
members including without limitation the vote required for any action by the
Board of Directors, and (b) that from time to time shall affect the directors'
power to manage and direct the business and affairs of the Corporation; and
Article V notwithstanding, no By-Law shall be adopted by the stockholders of the
Corporation which shall impair or impede the implementation of the foregoing.

The Board of Directors shall consist of a number of directors, which number
shall be determined from time to time exclusively by the Board of Directors
pursuant to a resolution adopted by affirmative vote of a majority of the entire
Board of Directors.  The directors shall be divided into three classes as nearly
equal in number as possible, designated Class I, Class II and Class III.  At the
1983 annual meeting of stockholders, Class I directors shall be elected for a
term expiring at the 1984 annual meeting of stockholders, Class II directors
shall be elected for a term expiring at the 1985 annual meeting of stockholders,
and Class III directors shall be elected for a term expiring at the 1986 annual
meeting of stockholders.  At each annual meeting of stockholders following such
initial classification and election, directors elected to succeed those
directors whose terms expire shall be elected for a term of office to expire at
the third succeeding annual meeting of stockholders after their election.


                                        6
<PAGE>


Notwithstanding the foregoing, whenever the holders of any one or more classes
or series of Preferred Stock shall have the right, voting separately by class or
series, to elect directors at an annual or special meeting of stockholders, the
election, term of office, filling of vacancies and other features of such
directorships shall be governed by the terms of the applicable designation of
the powers, preferences and rights made pursuant to Article III, and such
directors so elected shall not be divided into classes pursuant to this Article
IV unless expressly provided by such terms.

Subject to the rights of the holders of any class or series of the then
outstanding capital stock of the Corporation entitled to vote generally in the
election of directors, newly created directorships resulting from any increase
in the authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the directors
then in office, though less than a quorum, and directors so chosen shall hold
office for a term expiring at the annual meeting of stockholders at which the
term of office of the class to which they have been elected expires.  No
decrease in the number of authorized directors constituting the entire Board of
Directors shall shorten the term of any incumbent director.  Subject to the
rights of the holders of any class or series of the capital stock then
outstanding, any director, or the entire Board of Directors, may be removed from
office at any time, but only for cause.

No director of the Corporation shall be personally liable to the Corporation or
its stockholders for monetary damages for breach of fiduciary duty by such
director as a director; provided, however, that this Article IV shall not
eliminate or limit the liability of a director to the extent provided by
applicable law (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the General Corporation Law of Delaware, or (iv) for any
transaction from which the director derived an improper personal benefit.  No
amendment to or repeal of this Article IV shall apply to, or have any effect on,
the liability or alleged liability of any director of the Corporation for or
with respect to any acts or omissions of such director occurring prior to such
amendment or repeal.

                                    ARTICLE V

The Board of Directors may from time to time, by vote of a majority of its
members, alter, amend or rescind all or any of the By-Laws of the Corporation,
as permitted by law, subject to the power of the stockholders to change or
repeal such By-Laws.

                                   ARTICLE VI

     A.   (1)  In addition to any affirmative vote required by law or the
Certificate of Incorporation or By-Laws of the Corporation, and except as
otherwise expressly provided in paragraph B of this Article VI

               (a)  any merger or consolidation of the Corporation or any
          Subsidiary (as hereinafter defined) with (i) any Interested
          Stockholder (as hereinafter defined) or (ii) any other corporation
          (whether or not itself an Interested Stockholder) which is, or after
          such merger or consolidation would be, an Affiliate (as hereinafter
          defined) of an Interested Stockholder; or

               (b)  any sale, lease, exchange, mortgage, pledge, transfer or
          other disposition (in one transaction or a series of transactions) to
          or with any Interested Stockholder or any Affiliate of any Interested
          Stockholder involving any assets or securities of the Corporation, any
          Subsidiary or any Interested Stockholder or any Affiliate of any
          Interested Stockholder, having an aggregate Fair Market Value (as
          hereinafter defined) of $10,000,000 or more; or

               (c)  the adoption of any plan or proposal for the liquidation or
          dissolution of the Corporation proposed by or on behalf of an
          Interested Stockholder or any Affiliate of any Interested Stockholder;
          or


                                        7
<PAGE>


               (d)  any reclassification of securities (including any reverse
          stock split), or recapitalization of the Corporation, or any merger or
          consolidation of the Corporation with any of its Subsidiaries or any
          other transaction (whether or not with or otherwise involving an
          Interested Stockholder) which has the effect, directly or indirectly,
          of increasing the proportionate share of any class of equity or
          convertible securities of the Corporation or any Subsidiary which is
          directly or indirectly beneficially owned by any Interested
          Stockholder or any Affiliate of any Interested Stockholder; or

               (e)  any agreement, contract or other arrangement providing for
          any one or more of the actions specified in clauses (a) to (d) of this
          subparagraph (1), shall require the affirmative vote of at least
          eighty percent (80%) of the voting power of all of the then
          outstanding shares of the Voting Stock (as hereinafter defined) voting
          together as a single class (it being understood that, for purposes of
          this Article VI, each share of the Preference Stock (as hereinafter
          defined) which is Voting Stock shall have the number of votes granted
          to it pursuant to the applicable Preferred Stock Designation (as
          hereinafter defined) or Article III of this Certificate of
          Incorporation).  Such affirmative vote shall be required
          notwithstanding the fact that no vote may be required, or that a
          lesser percentage may be specified, by law or in any agreement with
          any national securities exchange or otherwise.

          (2)  The term "Business Combination" as used in this Article VI shall
     mean any transaction which is referred to in any one or more of clauses (a)
     through (e) of subparagraph (1) of paragraph A.

     B.  The provisions of paragraph A of this Article VI shall not be
applicable to any particular Business Combination, and such Business Combination
shall require only such affirmative vote, if any, as is required by law and any
other provision of the Certificate of Incorporation or the By-Laws of the
Corporation, if all of the conditions specified in either of the following
subparagraphs (1) or (2) are met:

          (1)  The Business Combination shall have been approved (whether such
     approval is made prior to or subsequent to the acquisition of beneficial
     ownership of the Voting Stock which caused the Interested Stockholder to
     become an Interested Stockholder) by a majority of the Continuing Directors
     (as hereinafter defined).

          (2)  All of the following conditions shall have been met:

               (a)  The consideration to be received by holders of a particular
          class of outstanding Voting Stock shall be in cash or in the same form
          as previously paid by or on behalf of the Interested Stockholder in
          connection with its direct or indirect acquisition of beneficial
          ownership of shares of such class of Voting Stock.  If the
          consideration so paid for shares of any class of Voting Stock varied
          as to form, the form of consideration for such class of Voting Stock
          shall be either cash or the form used to acquire beneficial ownership
          of the largest number of shares of such class of Voting Stock
          previously acquired by the Interested Stockholder.

               (b)  The aggregate amount of (x) cash and (y) the Fair Market
          Value as of the date of the consummation of the Business Combination
          of consideration other than cash to be received per share by holders
          of Common Stock in such Business Combination shall be at least equal
          to the higher amount determined under subclauses (i) and (ii) below:

                    (i)  (if applicable) the highest per share price (including
               any brokerage commissions, transfer taxes and soliciting dealers'
               fees) paid by or on behalf of the Interested Stockholder for any
               share of Common Stock in connection with the acquisition by the
               Interested Stockholder of beneficial ownership of such share (x)
               within the two-year period immediately prior to the first public
               announcement of the proposal of the Business Combination (the
               "Announcement Date") or (y) in the transaction in which the
               Interested Stockholder became an Interested Stockholder,
               whichever is higher; and

<PAGE>
                    (ii)  the Fair Market Value per share of Common Stock on the
               Announcement Date or on the date on which the Interested
               Stockholder became an Interested Stockholder (such latter date is
               referred to in this Article VI as the "Determination Date"),
               whichever is higher.

               (c)  The aggregate amount of (x) cash and (y) the Fair Market
          Value as of the date of the consummation of the Business Combination
          of consideration other than cash to be received per share by holders
          of shares of any class of outstanding Preference Stock, shall be at
          least equal to the highest amount determined under subclauses (i),
          (ii) and (iii) below:

                    (i)  (if applicable) the highest per share price (including
               any brokerage commissions, transfer taxes and soliciting dealers'
               fees) paid by or on behalf of the Interested Stockholder for any
               share of such class of Preference Stock in connection with the
               acquisition by the Interested Stockholder of beneficial ownership
               of such share (x) within the two-year period immediately prior to
               the Announcement Date or (y) in the transaction in which the
               Interested Stockholder became an Interested Stockholder,
               whichever is higher;

                    (ii)  the Fair Market Value per share of such class of
               Preference Stock on the Announcement Date or on the Determination
               Date, whichever is higher; and

                    (iii)  the highest preferential amount per share to which
               the holders of shares of such class of Preference Stock would be
               entitled in the event of any voluntary or involuntary
               liquidation, dissolution or winding up of the affairs of the
               Corporation, regardless of whether the Business Combination to be
               consummated constitutes such an event.

               The provisions of this subparagraph (2)(c) shall be required to
               be met with respect to every class of outstanding Preference
               Stock, whether or not the Interested Stockholder has previously
               acquired beneficial ownership of any shares of a particular class
               of Preference Stock.

               (d) After such Interested Stockholder has become an Interested
          Stockholder and prior to the consummation of such Business
          Combination: (i) there shall have been no failure to declare and pay
          at the regular date therefor any full dividends (whether or not
          cumulative) on the outstanding Preference Stock, except as approved by
          a majority of the Continuing Directors; (ii) there shall have been (x)
          no reduction in the annual rate of dividends paid on the Common Stock
          (except as necessary to reflect any subdivision of the Common Stock),
          except as approved by a majority of the Continuing Directors, and (y)
          an increase in such annual rate of dividends as necessary to reflect
          any reclassification (including any reverse stock split),
          recapitalization, reorganization or any similar transaction which has
          the effect of reducing the number of outstanding shares of Common
          Stock unless the failure so to increase such annual rate is approved
          by a majority of the Continuing Directors; and (iii) such Interested
          Stockholder shall not have become the beneficial owner of any
          additional shares of Voting Stock except as part of the transaction
          which results in such Interested Stockholder becoming an Interested
          Stockholder and except in a transaction which, after giving effect
          thereto, would not result in any increase in the Interested
          Stockholder's percentage beneficial ownership of any class of Voting
          Stock.

               (e) After becoming an Interested Stockholder, such Interested
          Stockholder shall not have received the benefit, directly or
          indirectly (except proportionately as a stockholder of the
          Corporation), of any loans, advances, guarantees, pledges or other
          financial assistance or any tax credits or other tax advantages
          provided by the Corporation, whether in anticipation of or in
          connection with such Business Combination or otherwise.

               (f) A proxy or information statement describing the proposed
          Business Combination and complying with the requirements of the
          Securities Exchange Act of 1934 and the rules and regulations
          thereunder (the "Act") (or any subsequent provisions replacing such
          Act, rules or regulations) shall be mailed to all

          consummation of such Business Combination (whether or not such proxy
          or information statement is required to be mailed pursuant to such Act
          or any subsequent provisions).

               (g) Such Interested Stockholder shall not have made any major
          change in the Corporation's business or equity capital structure
          without the approval of a majority of the Continuing Directors.

     received" as used in subparagraphs (2)(b) and (c) of paragraph B of Article
     VI shall include the shares of Common Stock and/or the shares of any other
     class of Voting Stock retained by the holders of such shares.

     D.  Nothing contained in this Article VI shall be construed to relieve any
Interested Stockholder from any fiduciary obligation imposed by law.

     E.  The fact that any Business Combination complies with the provisions of
paragraph B of this Article VI shall not be construed to impose any fiduciary
duty, obligation or responsibility on the Board of Directors, or any member
thereof, to approve such Business Combination or recommend its adoption or
approval to the stockholders of the Corporation, nor shall such compliance
limit, prohibit or otherwise restrict in any manner the Board of Directors, or
any member thereof, with respect to evaluations of or actions and responses
taken with respect to such Business Combination.

     F.  Notwithstanding any other provisions of the Certificate of
Incorporation of the Corporation or any provision of law which might otherwise
permit a lesser vote or no vote, but in addition to any affirmative vote of the
holders



                                       11

shall not be required for, any amendment, repeal or adoption unanimously
recommended by the Board of Directors of the Corporation if all of such

               ECOLAB INC. (FORMERLY:  ECONOMICS LABORATORY, INC.)

                     --------------------------------------
                         PURSUANT TO SECTION 151 OF THE
                GENERAL CORPORATION LAW OF THE STATE OF DELAWARE
                     ---------------------------------------

          ECOLAB INC. (formerly:  ECONOMICS LABORATORY, INC.), a corporation
organized and existing under the General Corporation Law of the State of
Delaware (the "Corporation"), in accordance with the provisions of Section 103
thereof, and Section 151(g) thereof, DOES HEREBY CERTIFY:

          That pursuant to the authority conferred upon the Board of Directors
by the Restated Certificate of Incorporation of the Corporation, on February 14,
1986, the Board of Directors adopted a resolution creating a series of 400,000
shares of Preferred Stock designated as Series A Junior Participating Preferred
Stock;

          That on February 26, 1986, a Certificate of Designation, Preferences
and Rights relating to the Series A Junior Participating Preferred Stock was
filed pursuant to Section 151 of the General Corporation Law of the State of
Delaware;

          That pursuant to authority conferred upon the Board of Directors by
the Restated Certificate of Incorporation of the Corporation, on September 12,
1986, the Board of Directors adopted a resolution authorizing and directing an
increase of the number of shares of Series A Junior Participating Preferred
Stock from 400,000 to 500,000;

          That on November 14, 1986, a Certificate of Increase in the Number of
Shares of the Series A Junior Participating Preferred Stock was filed pursuant
to Section 151 of the General Corporation Law of the State of Delaware;

          That none of the 500,000 shares of Series A Junior Participating
Preferred Stock have been issued as of the date hereof; and

          That pursuant to the authority conferred upon the Board of Directors
by the Restated Certificate of Incorporation of the Corporation, on February 24,
1996, the Board of Directors adopted the following resolution authorizing and
directing an increase in the number of shares of Series A Junior Participating
Preferred Stock from 500,000 to 1,000,000 and an amendment and restatement of
the voting powers, preferences and relative, participating, optional and other
special rights of the shares of such series, and the qualifications, limitations
or restrictions thereof:



<PAGE>


          RESOLVED, That pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions of its Restated
Certificate of Incorporation, the Board of Directors hereby authorizes and
directs that (a) the number of shares of Series A Junior Participating Preferred
Stock of this Corporation be hereby increased in amount from 500,000 shares to
1,000,000 shares, (b) all previous adjustments to any of the terms and
provisions of the shares of such series shall be reset so that such terms and
provisions shall be without regard to any such previous adjustments and (c) the
voting powers, preferences and relative, participating, optional and other
special rights of the shares of such series, and the qualifications, limitations
or restrictions thereof be hereby amended and restated as follows:

          Section 1.  DESIGNATION AND AMOUNT.  The shares of such series shall
     be designated as "Series A Junior Participating Preferred Stock" and the
     number of shares constituting such series shall be 1,000,000.

          Section. 2.  DIVIDENDS AND DISTRIBUTIONS.

          (A)  Subject to the prior and superior rights of the holders of any
     shares of any series of Preferred Stock, if any, issued from time to time
     ranking prior and superior to the shares of Series A Junior Participating
     Preferred Stock with respect to dividends, the holders of shares of Series
     A Junior Participating Preferred Stock shall be entitled to receive, when,
     as and if declared by the Board of Directors out of funds legally available
     for the purpose, quarterly dividends payable in cash on the fifteenth day
     of February, May, August and November in each year (each such date being
     referred to herein as a "Quarterly Dividend Payment Date"), commencing on
     the first Quarterly Dividend Payment Date after the first issuance of a
     share or fraction of a share of Series A Junior Participating Preferred
     Stock, in an amount per share (rounded to the nearest cent) equal to the
     greater of (a) $1.00 or (b) subject to the provision for adjustment
     hereinafter set forth, 100 times the aggregate per share amount of all cash
     dividends, and 100 times the aggregate per share amount (payable in kind)
     of all non-cash dividends or other distributions other than a dividend
     payable in shares of Common Stock or a subdivision of the outstanding
     shares of Common Stock (by reclassification or otherwise), declared on the
     Common Stock, par value $1.00 per share, of the Corporation (the "Common
     Stock") since the immediately preceding Quarterly Dividend Payment Date,
     or, with respect to the first Quarterly Dividend Payment Date, since the
     first issuance of any share or fraction of a share of Series A Junior
     Participating Preferred Stock.  In the event the Corporation shall at any
     time after February 24, 1996 (the "Rights Declaration Date") (i) declare
     any dividend on Common Stock payable in shares of Common Stock, (ii)
     subdivide the outstanding Common Stock, or (iii) combine the outstanding
     Common Stock into a smaller number of shares, then in each such case the
     amount to which holders of shares of Series A Junior Participating
     Preferred Stock were entitled immediately prior to such event under clause
     (b) of the preceding sentence shall be adjusted by multiplying such amount
     by a fraction the numerator of which is the number of shares of Common
     Stock outstanding immediately after such event and the denominator of which
     is the number of shares of Common Stock that were outstanding immediately
     prior to such event.

          (B)  The Corporation shall declare a dividend or distribution on the
     Series A Junior Participating Preferred Stock as provided in paragraph (A)
     above immediately after it declares


                                        2
<PAGE>


     a dividend or distribution on the Common Stock (other than a dividend
     payable in shares of Common Stock); provided that, in the event no dividend
     or distribution shall have been declared on the Common Stock during the
     period between any Quarterly Dividend Payment Date and the next subsequent
     Quarterly Divided Payment Date, a dividend of $1.00 per share as such
     amount may be adjusted pursuant to the last sentence of the preceding
     paragraph on the Series A Junior Participating Preferred Stock shall
     nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

          (C)  Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Junior Participating Preferred Stock from the Quarterly
     Dividend Payment Date next preceding the date of issue of such shares of
     Series A Junior Participating Preferred Stock, unless the date of issue of
     such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Junior Participating
     Preferred Stock entitled to receive a quarterly dividend and before such
     Quarterly Dividend Payment Date, in either of which events such dividends
     shall begin to accrue and be cumulative from such Quarterly Dividend
     Payment Date.  Accrued but unpaid dividends shall not bear interest.
     Dividends paid on the shares of Series A Junior Participating Preferred
     Stock  in an amount less than the total amount of such dividends at the
     time accrued and payable on such shares shall be allocated pro rata on a
     share-by-share basis among all such shares at the time outstanding.  The
     Board of Directors may fix a record date for the determination of holders
     of shares of Series A Junior Participating Preferred Stock  entitled to
     receive payment of a dividend or distribution declared thereon, which
     record date shall be no more than 60 days prior to the date fixed for the
     payment thereof.

          Section 3.  VOTING RIGHTS.  The holders of shares of Series A Junior
     Participating Preferred Stock  shall have the following voting rights:

          (A)  Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Junior Participating Preferred Stock shall entitle
     the holder thereof to 100 votes on all matters submitted to a vote of the
     stockholders of the Corporation.  In the event the Corporation shall at any
     time after the Rights Declaration Date (i) declare any dividend on Common
     Stock payable in shares of Common Stock, (ii) subdivide the outstanding
     Common Stock, or (iii) combine the outstanding Common Stock into a smaller
     number of shares, then in each such case the number of votes per share to
     which holders of shares of Series A Junior Participating Preferred Stock
     were entitled immediately prior to such event shall be adjusted by
     multiplying such number by a fraction the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          (B)  Except as otherwise provided herein or by law, the holders of
     shares of Series A Junior Participating Preferred Stock  and the holders of
     shares of Common Stock shall vote together as one class on all matters
     submitted to a vote of stockholders of the Corporation.

          (C)  (i)  If at any time dividends on any Series A Junior
          Participating Preferred


                                        3
<PAGE>


          Stock  shall be in arrears in an amount equal to six (6) quarterly
          dividends thereon, the occurrence of such contingency shall mark the
          beginning of a period (herein called a "default period") which shall
          extend until such time when all accrued and unpaid dividends for all
          previous quarterly dividend periods and for the current quarterly
          dividend period on all shares of Series A Junior Participating
          Preferred Stock then outstanding shall have been declared and paid or
          set apart for payment.  During each default period, all holders of
          Preferred Stock (including holders of the Series A Junior
          Participating Preferred Stock) with dividends in arrears in an amount
          equal to six (6) quarterly dividends thereon, voting as a class,
          irrespective of series, shall have the right to elect two (2)
          Directors.

               (ii) During any default period, such voting right of the holders
          of Series A Junior Participating Preferred Stock may be exercised
          initially at a special meeting called pursuant to subparagraph (iii)
          of this Section 3(C) or at any annual meeting of stockholders, and
          thereafter at annual meetings of stockholders, provided that neither
          such voting right nor the right of the holders of any other series of
          Preferred Stock, if any, to increase, in certain cases, the authorized
          number of Directors shall be exercised unless the holders of ten
          percent (10%) in number of shares of Preferred Stock outstanding shall
          be present in person or by proxy.  The absence of a quorum of the
          holders of Common Stock shall not affect the exercise by the holders
          of Preferred Stock of such voting right.  At any meeting at which the
          holders of Preferred Stock shall exercise such voting right initially
          during an existing default period, they shall have the right, voting
          as a class, to elect Directors to fill such vacancies, if any, in the
          Board of Directors as may then exist up to two (2) Directors or, if
          such right is exercised at an annual meeting, to elect two (2)
          Directors.  If the number which may be so elected at any special
          meeting does not amount to the required number, the holders of the
          Preferred Stock shall have the right to make such increase in the
          number of Directors as shall be necessary to permit the election by
          them of the required number.  After the holders of the Preferred Stock
          shall have exercised their right to elect Directors in any default
          period and during the continuance of such period, the number of
          Directors shall not be increased or decreased except by vote of the
          holders of Preferred Stock as herein provided or pursuant to the
          rights of any equity securities ranking senior to or PARI PASSU with
          the Series A Junior Participating Preferred Stock.

               (iii)     Unless the holders of Preferred Stock shall, during an
          existing default period, have previously exercised their right to
          elect Directors, the Board of Directors may order, or any stockholder
          or stockholders owning in the aggregate not less than ten percent
          (10%) of the total number of shares of Preferred Stock outstanding,
          irrespective of series, may request, the calling of a special meeting
          of the holders of Preferred Stock, which meeting shall thereupon be
          called by the President, a Vice-President or the Secretary of the
          Corporation.  Notice of such meeting and of any annual meeting  at
          which holders of Preferred Stock are entitled to vote pursuant to this
          paragraph (C) (iii) shall be given to each holder of record of
          Preferred Stock by mailing a copy of such notice to him at his last
          address as the same appears on the books of the Corporation.  Such
          meeting shall be called for a time not earlier than 20


                                        4
<PAGE>


          days and not later than 60 days after such order or request or in
          default of the calling of such meeting within 60 days after such order
          or request, such meeting may be called on similar notice by any
          stockholder or stockholders owning in the aggregate not less than ten
          percent (10%) of the total number of shares of Preferred Stock
          outstanding.  Notwithstanding the provisions of this paragraph
          (C)(iii),  no such special meeting shall be called during the period
          within 60 days immediately preceding the date fixed for the next
          annual meeting of the stockholders.

               (iv) In any default period, the holders of Common Stock, and
          other classes of stock of the Corporation if applicable, shall
          continue to be entitled to elect the whole number of Directors until
          the holders of Preferred Stock shall have exercised their right to
          elect two (2) Directors voting as a class, after the exercise of which
          right (x) the Directors so elected by the holders of Preferred Stock
          shall continue in office until their successors shall have been
          elected by such holders or until the expiration of the default period,
          and (y) any vacancy in the Board of Directors may (except as provided
          in paragraph (C)(ii) of this Section 3) be filled by vote of a
          majority of the remaining Directors theretofore elected by the holders
          of the class of stock which elected the Director whose office shall
          have become vacant.  References in this paragraph (C) to Directors
          elected by the holders of a particular class of stock shall include
          Directors elected by such Directors to fill vacancies as provided in
          clause (y) of the foregoing sentence.

               (v)  Immediately upon the expiration of a default period, (x) the
          right of the holders of Preferred Stock as a class to elect Directors
          shall cease, (y) the term of any Directors elected by the holders of
          Preferred Stock as a class shall terminate, and (z) the number of
          Directors shall be such number as may be provided for in the
          Certificate of Incorporation or by-laws irrespective of any increase
          made pursuant to the provisions of paragraph (C)(ii) of this Section 3
          (such number being subject, however, to change thereafter in any
          manner provided by law or in the Certificate of Incorporation or by-
          laws).  Any vacancies in the Board of Directors effected by the
          provisions of clauses (y) and (z) in the preceding sentence may be
          filled by a majority of the remaining Directors.

          (D)   Except as set forth herein, holders of Series A Junior
     Participating Preferred Stock  shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

          Section 4.  CERTAIN RESTRICTIONS.

          (A)  Whenever quarterly dividends or other dividends or distributions
     payable on the Series A Junior Participating Preferred Stock  as provided
     in Section 2 are in arrears, thereafter and until all accrued and unpaid
     dividends and distributions, whether or not declared, on shares of Series A
     Junior Participating Preferred Stock  outstanding shall have been paid in
     full, the Corporation shall not


                                        5
<PAGE>


               (i)  declare or pay dividends on, make any other distributions
          on, or redeem or purchase or otherwise acquire for consideration any
          shares of stock ranking junior (either as to dividends or upon
          liquidation, dissolution or winding up) to the Series A Junior
          Participating Preferred Stock;

               (ii) declare or pay dividends on or make any other distributions
          on any shares of stock ranking on a parity (either as to dividends or
          upon liquidation, dissolution or winding up) with the Series A Junior
          Participating Preferred Stock, except dividends paid ratably on the
          Series A Junior Participating Preferred Stock and all such parity
          stock on which dividends are payable or in arrears in proportion to
          the total amounts to which the holders of all such shares are then
          entitled;

               (iii)     redeem or purchase or otherwise acquire for
          consideration shares of any stock ranking on a parity (either as to
          dividends or upon liquidation, dissolution or winding up) with the
          Series A Junior Participating Preferred Stock, provided that the
          Corporation may at any time redeem, purchase or otherwise acquire
          shares of any such parity stock in exchange for shares of any stock of
          the Corporation ranking junior (either as to dividends or upon
          dissolution, liquidation or winding up) to the Series A Junior
          Participating Preferred Stock or;

               (iv) purchase or otherwise acquire for consideration any shares
          of Series A Junior Participating Preferred Stock, or any shares of
          stock ranking on a parity with the Series A Junior Participating
          Preferred Stock, except in accordance with a purchase offer made in
          writing or by publication (as determined by the Board of Directors) to
          all holders of such shares upon such terms as the Board of Directors,
          after consideration of the respective annual dividend rates and other
          relative rights and preferences of the respective series and classes,
          shall determine in good faith will result in fair and equitable
          treatment among the respective series or classes.

          (B)  The Corporation shall not permit any subsidiary of the
     Corporation to purchase or otherwise acquire for consideration any shares
     of stock of the Corporation unless the Corporation could, under paragraph
     (A) of this Section 4, purchase or otherwise acquire such shares at such
     time and in such manner.

          Section 5.  REACQUIRED SHARES.  Any shares of Series A Junior
     Participating Preferred Stock purchased or otherwise acquired by the
     Corporation in any manner whatsoever shall be retired and cancelled
     promptly after the acquisition thereof.  All such shares shall upon their
     cancellation become authorized but unissued shares of Preferred Stock and
     may be reissued as part of a new series of Preferred Stock to be created by
     resolution or resolutions of the Board of Directors, subject to the
     conditions and restrictions on issuance set forth herein.

          Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.

          (A)  Upon any liquidation (voluntary or otherwise), dissolution or
     winding up of the Corporation, no distribution shall be made to the holders
     of shares of stock ranking junior (either as to dividends or upon
     liquidation, dissolution or winding up) to the Series A Junior
     Participating Preferred Stock unless, prior thereto, the holders of shares
     of Series A Junior Participating Preferred Stock shall have received $100
     per share, plus an amount equal to accrued and unpaid dividends and
     distributions thereon, whether or not declared, to the date of such payment
     (the "Series A Liquidation Preference").  Following the payment of the full
     amount of the Series A Liquidation Preference, no additional distributions
     shall be made to the holders of shares of Series A Junior Participating
     Preferred Stock unless, prior thereto, the holders of shares of Common
     Stock shall have received an amount per share (the "Common Adjustment")
     equal to the quotient obtained by dividing (i) the Series A Liquidation
     Preference by (ii) 100 (as appropriately adjusted as set forth in
     subparagraph (C) below to reflect such events as stock splits, stock
     dividends and recapitalization with respect to the Common Stock) (such
     number in clause (ii), the "Adjustment Number").  Following the payment of
     the full amount of the Series A Liquidation Preference and the Common
     Adjustment in respect of all outstanding shares of Series A Junior
     Participating Preferred Stock  and Common Stock, respectively, holders of
     Series A Junior Participating Preferred Stock and holders of shares of
     Common Stock shall receive their ratable and proportionate share of the
     remaining assets to be distributed in the ratio of the Adjustment Number to
     1 with respect to such Preferred Stock and Common Stock, on a per share
     basis, respectively.

          (B)  In the event, however, that there are not sufficient assets
     available to permit payment in full of the Series A Liquidation Preference
     and the liquidation preferences of all other series of preferred stock, if
     any, which rank on a parity with the Series A Junior Participating
     Preferred Stock, then such remaining assets shall be distributed ratably to
     the holders of such parity shares in proportion to their respective
     liquidation preferences.  In the event, however, that there are not
     sufficient assets available to permit payment in full of the Common
     Adjustment, then such remaining assets shall be distributed ratably to the
     holders of Common Stock.

          (C)  In the event the Corporation shall at any time after the Rights
     Declaration Date (i) declare any dividend on Common Stock payable in shares
     of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
     combine the outstanding Common Stock into a smaller number of shares, then
     in each such case the Adjustment Number in effect immediately prior to such
     event shall be adjusted by multiplying such Adjustment Number by a fraction
     the numerator of which is the number of shares of Common Stock outstanding
     immediately after such event and the denominator of which is the number of
     shares of Common Stock that were outstanding immediately prior to such
     event.

          Section 7.  CONSOLIDATION, MERGER, ETC.  In case the corporation shall
     enter into any consolidation, merger, combination or other transaction in
     which the shares of Common Stock are exchanged for or changed into other
     stock or securities, cash and/or any other property, then in any such case
     the shares of Series A Junior Participating Preferred Stock  shall at the
     same time be similarly exchanged or changed in an amount per share (subject
     to the provision


                                        7
<PAGE>


     for adjustment hereinafter set forth) equal to 100 times the aggregate
     amount of stock, securities, cash and/or any other property (payable in
     kind), as the case may be, into which or for which each share of Common
     Stock is changed or exchanged.  In the event the Corporation shall at any
     time after the Rights Declaration Date (i) declare any dividend on Common
     Stock payable in shares of Common Stock, (ii) subdivide the outstanding
     Common Stock, or (iii) combine the outstanding Common Stock into a smaller
     number of shares, then in each such case the amount set forth in the
     preceding sentence with respect to the exchange or change of shares of
     Series A Junior Participating Preferred Stock shall be adjusted by
     multiplying such amount by a fraction the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          Section 8.  NO REDEMPTION.   The shares of Series A Junior
     Participating Preferred Stock shall not be redeemable.

          Section 9.  RANKING.  The Series A Junior Participating Preferred
     Stock shall rank junior to all other series of the Corporation's Preferred
     Stock which may be issued from time to time as to the payment of dividends
     and the distribution of assets, unless the terms of any such series shall
     provide otherwise.

          Section 10.  AMENDMENT.  The Restated Certificate of Incorporation of
     the Corporation shall not be further amended in any manner which would
     materially alter or change the powers, preferences or special rights of the
     Series A Junior Participating Preferred Stock  so as to affect them
     adversely without the affirmative vote of the holders of a majority or more
     of the outstanding shares of Series A Junior Participating Preferred Stock,
     voting separately as a class.

          Section 11.  FRACTIONAL SHARES.  Series A Junior Participating
     Preferred Stock may be issued in fractions of a share which shall entitle
     the holder, in proportion to such holder's fractional shares, to exercise
     voting rights, receive dividends, participate in distributions and to have
     the benefit of all other rights of holders of Series A Junior Participating
     Preferred Stock.

          That this Amended Certificate will be effective as of the close of
business on March 11, 1996.

          IN WITNESS WHEREOF, said ECOLAB INC. has caused this Amended
Certificate to be signed by Kenneth A. Iverson, its Vice President and
Secretary, this 11th day of March, 1996.

RE:  ECOLAB INC. 1997 NON-EMPLOYEE DIRECTOR DEFERRED COMPENSATION PLAN
     REGISTRATION ON FORM S-8

Gentlemen:

I am Vice President and Secretary of Ecolab Inc. (the "Company").  In that
capacity, I have acted as counsel to the Company in connection with the proposed
offering by the Company pursuant to a Registration Statement on Form S-8 under
the Securities Act of 1933, as amended, of 125,000 shares of the Company's
Common Stock, $1.00 par value ("the Shares"), and the Company's preferred stock
purchase rights (the "Rights") adhering to the Shares, in connection with the
Ecolab Inc. 1997 Non-Employee Director Deferred Compensation Plan (the 
"Plan").  I understand that it is the Company's intention that the Shares 
will be (a) issued out of authorized but unissued shares, or (b) transferred 
out of treasury shares held by the Company now or in the future; provided, 
that no Shares will be issued or transferred until the Plan has been approved 
by a majority of the total votes cast by the holders of shares present in 
person or represented by proxy and entitled to vote on the Plan at the next  
annual meeting of stockholders of the Company.

I have examined the proposed Registration Statement on Form S-8, the Plan, the
Rights Agreement between the Company and First Chicago Trust Company of New York
dated as of February 24, 1996, (the "Rights Agreement"), and such other
documents, corporate records and instruments and such laws and regulations as I
have considered relevant for the purpose of this opinion.  Based upon the
foregoing, I am of the opinion that:

     (1)  The Company has been duly incorporated and is validly existing as a
          corporation in good standing under the laws of the state of Delaware.

     (2)  The Shares, when issued or transferred, delivered and paid for in
          accordance with the Plan as approved by the



<PAGE>


          stockholders in the manner set forth in the first paragraph of this
          letter, will be legally issued, fully paid and non-assessable.

     (3)  The Rights, when issued in accordance with the Rights Agreement in
          connection with Shares issued or transferred in accordance with the
          Plan (so long as the Rights are attached to the Shares in accordance
          with the Rights Agreement), will be legally issued, fully paid and
          non-assessable.

I hereby consent to the filing of this opinion as Exhibit 5.1 to the
above-captioned Registration Statement and to its use as part of the
Registration Statement.

Sincerely,



/s/ Kenneth A. Iverson
Kenneth A. Iverson
Vice President and Secretary
