<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On May&nbsp;27, 1999, a total of 12,000,000 shares of

with the Ecolab Inc. 1997 Stock Incentive Plan (the &#147;1997 Plan&#148;).&#160; On February&nbsp;22, 2002, the Board of
Directors of Ecolab adopted the Ecolab Inc. 2002 Stock Incentive Plan (the &#147;2002

12,000,000 shares of common stock for issuance under the 2002 Plan, plus any
shares of common stock which, as of the May&nbsp;10, 2002 effective date of the
2002 Plan, were reserved for issuance under the 1997 Plan and are not
thereafter issued and would otherwise have been available under the 1997
Plan.&#160; On August&nbsp;9, 2002, a
Registration Statement on Form&nbsp;S-8 (File No.&nbsp;333-97927) was filed by
Ecolab to (a)&nbsp;register 12,000,000 &#147;new&#148; shares for the 2002 Plan and (b)&nbsp;register

have become available for the 2002 Plan.&#160;

indemnified against expenses (including attorneys&#146; fees) actually and

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.&#160; Section&nbsp;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

<p style="margin:0in 0in .0001pt;text-indent:0in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">of their fiduciary duty as directors, except (1)&nbsp;for a breach of
the duty of loyalty, (2)&nbsp;for acts or omissions not in good faith or which
involve intentional misconduct or knowing violation of the law, (3)&nbsp;for
willful or negligent violations of certain provisions under the General
Corporation Law of Delaware imposing certain requirements with respect to stock
repurchases, redemptions and dividends, or (4)&nbsp;for any transaction from
which the director derived an improper personal benefit.&#160; Subject to these exceptions, under Article&nbsp;IV,
directors do not have any personal liability to Ecolab or its stockholders for
any violation of their fiduciary duty.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Ecolab 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 General Corporation
Law of Delaware and claims and suits arising under the Securities Act.&#160; 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 Ecolab.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Ecolab has entered into indemnification agreements
with each of its directors.&#160; These
indemnification agreements provide for the prompt indemnification &#147;to the
fullest extent permitted by law&#148; and for the prompt advancement of expenses,
including attorneys&#146; 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 the director is or was a
director, officer, employee, trustee, agent or fiduciary of Ecolab or is or was
serving at the request of Ecolab 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.&#160;
The indemnification agreements further provide that Ecolab has the burden
of proving that a director is not entitled to indemnification in any particular
case.</font></p>

EXPLANATORY NOTE
(All share amounts stated in the paragraph
below have been adjusted for a 2 for 1 stock split on June 6, 2003.)
On May 27, 1999, a total of 12,000,000 shares of
the common stock (with preferred stock purchase rights) of Ecolab Inc. ("Ecolab")
were registered with the Securities and Exchange Commission ("SEC") by a
Registration Statement on Form S-8 (File No. 333-79449) in connection
with the Ecolab Inc. 1997 Stock Incentive Plan (the "1997 Plan").  On February 22, 2002, the Board of
Directors of Ecolab adopted the Ecolab Inc. 2002 Stock Incentive Plan (the "2002
Plan").  The Board reserved a maximum of
12,000,000 shares of common stock for issuance under the 2002 Plan, plus any
shares of common stock which, as of the May 10, 2002 effective date of the
2002 Plan, were reserved for issuance under the 1997 Plan and are not
thereafter issued and would otherwise have been available under the 1997
Plan.  On August 9, 2002, a
Registration Statement on Form S-8 (File No. 333-97927) was filed by
Ecolab to (a) register 12,000,000 "new" shares for the 2002 Plan and (b) register
2,200,000 shares that were remaining and unissued under the 1997 Plan as of the
effective date.
Subsequent to the effective date, an additional
1,405,378 shares of Ecolab common stock previously reserved for issuance under
the 1997 Plan became available for the 2002 Plan and on May 17, 2004, a
Registration Statement on Form S-8 (File No. 333-115568) was filed by
Ecolab to register such additional 1,405,378 shares.
Also, subsequent to the filing of the Registration
Statement on Form S-8 on May 17, 2004, an additional 271,698 shares
of Ecolab common stock previously reserved for issuance under the 1997 Plan
have become available for the 2002 Plan. 
Pursuant to Instruction E to Form S-8, these 271,698 shares are
hereby registered on this new Registration Statement on Form S-8 in
connection with the 2002 Plan.
Additional shares under the 1997 Plan may become
available in the future, and may also be registered for issuance under the 2002
Plan pursuant to subsequent Registration Statements.

Experts
The
financial statements incorporated in this Registration Statement by reference
to the Annual Report on Form 10-K for the year ended December 31,
2004 have been so incorporated in reliance on the report of
PricewaterhouseCoopers LLP, an independent registered public accounting firm,
given on the authority of said firm as experts in auditing and accounting.
Independent
Registered Public Accounting Firm
With
respect to the unaudited consolidated financial information of Ecolab Inc.
incorporated by reference in this Registration Statement,
PricewaterhouseCoopers LLP reported that they have applied limited procedures
in accordance with professional standards for a review of such
information.  However, their separate
reports dated April 21, 2005, July 25, 2005 and October 21, 2005
incorporated by reference herein, state that they did not audit and they do not
express an opinion on that unaudited consolidated 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. 
PricewaterhouseCoopers LLP is not subject to the liability provisions of
Section 11 of the Securities Act for their reports on the unaudited
financial information because each such report is not a "report" or a "part" of
the registration statement prepared or certified by PricewaterhouseCoopers LLP
within the meaning of Sections 7 and 11 of the Securities Act.

Item 4.
Description
of Securities.
Not applicable. 
Ecolab's common stock and preferred stock purchase rights to be offered
and sold pursuant to this registration statement are registered under Section 12
of the Exchange Act.
Item 5.
Interests
of Named Experts and Counsel.
The validity of the securities has been passed upon by
Timothy P. Dordell, Associate General Counsel – Corporate and Assistant
Secretary for Ecolab.  Mr. Dordell
beneficially owns shares of Ecolab common stock and has options to purchase
Ecolab common stock under Ecolab stock incentive plans.
Item 6.
Indemnification
of Directors and Officers.
Subsection (a) of Section 145 of the
General Corporation Law of Delaware 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 the action or suit was brought shall determine
that, despite the adjudication of liability, the person is fairly and
reasonably entitled to indemnity for the 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 defense of any claim, issue or matter therein, the 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 the person in any such capacity or arising out of the person's status as
such, whether or not the corporation would have the power to indemnify the
person against such liabilities under Section 145, including liabilities
under the Securities Act.
Article V of Ecolab's By-Laws provides for
indemnification of Ecolab's officers and directors to the full extent allowed
by Delaware law.
In addition, Article IV of Ecolab's Restated
Certificate of Incorporation provides that Ecolab's directors do not have
personal liability to Ecolab or its stockholders for monetary damages for any
breach
3
of their fiduciary duty as directors, except (1) for a breach of
the duty of loyalty, (2) for acts or omissions not in good faith or which
involve intentional misconduct or knowing violation of the law, (3) for
willful or negligent violations of certain provisions under the General
Corporation Law of Delaware imposing certain requirements with respect to stock
repurchases, redemptions and dividends, or (4) 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 Ecolab or its stockholders for
any violation of their fiduciary duty.
Ecolab 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 General Corporation
Law of Delaware 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 Ecolab.
Ecolab has entered into indemnification agreements
with each of its directors.  These
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 the director is or was a
director, officer, employee, trustee, agent or fiduciary of Ecolab or is or was
serving at the request of Ecolab 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 Ecolab 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 General Corporation Law of Delaware, Ecolab's By-Laws and
Restated Certificate of Incorporation, Ecolab's directors and officers
liability insurance coverage and the indemnification agreements for purposes of
general description only.

Item 9.
Undertakings.
(a)
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;
(ii)
To
reflect in the prospectus any facts or events arising after the effective date
of this registration statement (or the most recent post-effective amendment
hereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in this 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 SEC pursuant to Rule 424(b) under
the Securities Act 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;
(iii)
To
include any material information with respect to the plan of distribution not
previously disclosed in this Registration Statement or any material change to
such information in this Registration Statement.
Provided
,
however
,
that paragraphs (a)(1)(i) and (a)(1)(ii) above 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 SEC
by the registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in this Registration Statement.
(2)
That,
for the purpose of determining any liability under the Securities Act, 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.
(b)
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 Section 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 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.
(c)
Insofar
as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the SEC 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
5
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.
