<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">subsidiaries that are in
addition to those provided under the Ecolab Savings Plan and ESOP (the &#147;Savings
Plan&#148;).&#160; Ecolab and such subsidiaries
will partially match deferrals made by employees participating in the Plan.
Both the employee deferrals and the employer matching contributions are
credited to individual accounts established and maintained on the books of
Ecolab or such subsidiary in the name of each participating employee.&#160; The obligations of Ecolab to its
participating employees, as well as the obligations of certain of its
subsidiaries to the participating employees of such subsidiaries, to the extent
such subsidiary obligations have been guaranteed by Ecolab (collectively the &#147;Deferred
Compensation Obligations&#148;), which are represented by the accounts will be unsecured
general obligations of Ecolab to pay deferred compensation in the future in
accordance with the terms of the Plan and will rank pari passu with other
unsecured and unsubordinated indebtedness of Ecolab from time to time
outstanding.</font></p>

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

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The amount of compensation
to be deferred by each participating employee will be determined in accordance
with the Plan based on elections by the employee.&#160; Each Deferred Compensation Obligation will be
payable by Ecolab in accordance with the terms of the Plan.&#160; </font>Except as to the restrictions on the Plan&#146;s Ecolab Stock Fund effective
January&nbsp;1, 2006, the investment options under the Plan generally are the
same as those offered for the Savings Plan.&#160;
Employee deferrals and employer matching contributions earn the rate of
return equal to the rate of return of the designated investment funds.&nbsp;
However, unlike the Savings Plan, assets are not actually invested in the
designated funds.&nbsp; Subject to certain forfeiture provisions, participants
are 100% vested in their deferrals and the employer matching contributions.</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>

participant&#146;s right or the right of any other person to the Deferred
Compensation Obligations cannot be assigned, alienated, sold, garnished,
transferred, pledged or encumbered except (i)&nbsp;pursuant to the beneficiary
provisions under the Plan or (ii)&nbsp;by an Internal Revenue Service levy for
unpaid taxes.</font></p>

<p style="margin:0in 0in .0001pt;"><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;">The Deferred
Compensation Obligations are not subject to redemption, in whole or in part,
prior to the payment dates specified in the Plan, except in limited
circumstances where total or partial redemption may, in the sole discretion of
the Plan&#146;s administrator, be necessary in order to alleviate the consequences
of an unforeseen emergency faced by the participating employee.&#160; However, Ecolab reserves the right to amend
or terminate the Plan at any time, except that no such amendment or termination
shall adversely affect the right of an employee participant to the balance of
his or her account as of the date of such amendment or termination; provided,
however, that this limitation shall not apply to any amendment or termination
that is deemed necessary or reasonable (as determined in the sole discretion of
the Committee) to comply with the requirements of Code Section&nbsp;409A and
the guidance issued under the American Jobs Creation Act of 2004.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Deferred
Compensation Obligations are not convertible into any other security of Ecolab.
The Deferred Compensation Obligations will not have the benefit of a negative
pledge or any other affirmative or negative covenant on the part of
Ecolab.&#160; No trustee has been appointed
having the authority to take action with respect to the Deferred Compensation
Obligations, and each employee participant will be responsible for acting
independently with respect to, among other things, the giving of notice,
responding to any requests for consents, waivers or amendments pertaining to
the Deferred Compensation Obligations, enforcing covenants and taking action
upon default.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Subsection&nbsp;(a)&nbsp;of
Section&nbsp;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&#146; fees), judgments, fines and amounts paid

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

unlawful.</font></p>

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

Section&nbsp;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

brought shall determine that, despite the adjudication of liability, the person

shall deem proper.</font></p>

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)&nbsp;and (b)&nbsp;or in the defense of any claim, issue or
matter therein, the person shall be indemnified against expenses (including
attorneys&#146; fees) actually and reasonably incurred in connection therewith; that
indemnification provided for by Section&nbsp;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.&#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
by the person in any such capacity or arising out of the person&#146;s status as
such, whether or not the corporation would have the power to indemnify the

<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

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

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

officer, employee, trustee, agent or fiduciary of another corporation,
partnership, joint venture, employee benefit plan trust or other enterprise, or

expressed in the Securities Act, and is, therefore, unenforceable.&#160; In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.</font></p>

Mirror Savings (the "Plan"), Ecolab and certain subsidiaries will provide
deferred compensation benefits to certain management and highly compensated
employees of Ecolab and such
2
subsidiaries that are in
addition to those provided under the Ecolab Savings Plan and ESOP (the "Savings
Plan").  Ecolab and such subsidiaries
will partially match deferrals made by employees participating in the Plan.
Both the employee deferrals and the employer matching contributions are
credited to individual accounts established and maintained on the books of
Ecolab or such subsidiary in the name of each participating employee.  The obligations of Ecolab to its
participating employees, as well as the obligations of certain of its
subsidiaries to the participating employees of such subsidiaries, to the extent
such subsidiary obligations have been guaranteed by Ecolab (collectively the "Deferred
Compensation Obligations"), which are represented by the accounts will be unsecured
general obligations of Ecolab to pay deferred compensation in the future in
accordance with the terms of the Plan and will rank pari passu with other
unsecured and unsubordinated indebtedness of Ecolab from time to time
outstanding.
The amount of compensation
to be deferred by each participating employee will be determined in accordance
with the Plan based on elections by the employee.  Each Deferred Compensation Obligation will be
payable by Ecolab in accordance with the terms of the Plan.
Except as to the restrictions on the Plan's Ecolab Stock Fund effective
January 1, 2006, the investment options under the Plan generally are the
same as those offered for the Savings Plan. 
Employee deferrals and employer matching contributions earn the rate of
return equal to the rate of return of the designated investment funds. 
However, unlike the Savings Plan, assets are not actually invested in the
designated funds.  Subject to certain forfeiture provisions, participants
are 100% vested in their deferrals and the employer matching contributions.
An employee
participant's right or the right of any other person to the Deferred
Compensation Obligations cannot be assigned, alienated, sold, garnished,
transferred, pledged or encumbered except (i) pursuant to the beneficiary
provisions under the Plan or (ii) by an Internal Revenue Service levy for
unpaid taxes.
The Deferred
Compensation Obligations are not subject to redemption, in whole or in part,
prior to the payment dates specified in the Plan, except in limited
circumstances where total or partial redemption may, in the sole discretion of
the Plan's administrator, be necessary in order to alleviate the consequences
of an unforeseen emergency faced by the participating employee.  However, Ecolab reserves the right to amend
or terminate the Plan at any time, except that no such amendment or termination
shall adversely affect the right of an employee participant to the balance of
his or her account as of the date of such amendment or termination; provided,
however, that this limitation shall not apply to any amendment or termination
that is deemed necessary or reasonable (as determined in the sole discretion of
the Committee) to comply with the requirements of Code Section 409A and
the guidance issued under the American Jobs Creation Act of 2004.
The Deferred
Compensation Obligations are not convertible into any other security of Ecolab.
The Deferred Compensation Obligations will not have the benefit of a negative
pledge or any other affirmative or negative covenant on the part of
Ecolab.  No trustee has been appointed
having the authority to take action with respect to the Deferred Compensation
Obligations, and each employee participant will be responsible for acting
independently with respect to, among other things, the giving of notice,
responding to any requests for consents, waivers or amendments pertaining to
the Deferred Compensation Obligations, enforcing covenants and taking action
upon default.

5.  Interests of Named Experts and
Counsel.

offered hereby, is eligible for participation in the Plan.

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 the 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 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 General
Corporation Law of Delaware 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 Ecolab or its stockholders for
any violation of their fiduciary duty.
4
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 thereof)
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
5
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 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.
