                                PROXY STATEMENT
                         ANNUAL MEETING OF STOCKHOLDERS
                                  MAY 14, 1999
 
This Proxy Statement, which is first being mailed to stockholders on or about
March 31, 1999, is furnished in connection with the solicitation of proxies on
behalf of the Board of Directors of Ecolab Inc., a Delaware corporation
(hereinafter called the "Company"), from holders of Common Stock of the Company,
to be voted at the Annual Meeting of Stockholders to be held at 10:00 a.m. on
Friday, May 14, 1999, and at any adjournment thereof.
 
Holders of Common Stock of record at the close of business on March 16, 1999
will be entitled to vote at the meeting and any adjournment thereof. At that
time, the Company had outstanding and entitled to vote 129,597,754 shares of
Common Stock. Each of such shares is entitled to one vote on each matter
presented at the meeting. The presence at the meeting, in person or by proxy, of
the holders of a majority of the issued and outstanding shares of Common Stock
entitled to vote, is required for a quorum for the transaction of business.
Shares represented by a proxy with instructions to abstain and any shares
represented by a limited proxy (i.e., a broker non-vote) will be counted in
determining whether a quorum is present.
 
If the stockholder is a participant in the Company's Dividend Reinvestment Plan
or a participant in the Company's Employee Stock Purchase Plan, the proxy
represents the number of shares held on account of the participant in those
plans as well as shares held of record by the participant. With respect to
participants and beneficiaries of the Company's defined contribution 401(k)
Savings Plan, the proxy also serves as the voting instruction card to the plan
trustee and represents the stockholder's proportional interest in shares of
Common Stock beneficially held by the trustee.
 
Stockholders described in the two immediately preceding paragraphs may vote (or
in the case of participants and beneficiaries of the Company's defined
contribution 401(k) Savings Plan, instruct the trustee) by telephone or the
Internet using the instructions indicated on the proxy card.
 
Proxies in proper form received by the time of the meeting will be voted as
specified. A stockholder giving a proxy may revoke it at any time before it is
exercised by submitting a written revocation to the Secretary of the Company,
submitting a subsequently dated proxy, voting by telephone or Internet at a
later time, or by attending the meeting and voting in person.
 
The Company will bear the cost of the preparation and solicitation of proxies,
including the charges and expenses of brokerage firms, banks or other nominees
for forwarding proxy material to beneficial owners. In addition to solicitation
by mail, proxies may be solicited by telephone, the Internet or personally. The
Company has retained Georgeson & Company Inc., Wall Street Plaza, New York, NY
10005, to aid in the solicitation of proxies for a fee of $8,000 plus expenses.
Proxies may also be solicited by certain directors, officers and employees of
the Company without extra compensation.

The following table sets forth information as to entities which have reported to
the Securities and Exchange Commission ("SEC") or have advised the Company that
they are a "beneficial owner," as defined by the SEC rules and regulations, of
more than 5% of the Company's outstanding Common Stock.

</TABLE>
 
(1)  The percent of class is based on the number of voting shares outstanding as
    of March 16, 1999.
 
(2)  Henkel KGaA is a partnership limited by shares organized under the laws of
    Germany. The Company understands that the majority of the voting stock of
    Henkel KGaA is controlled by members of the Henkel family. Voting shares of
    the Company beneficially owned by Henkel KGaA are subject to an agreement
    containing certain restrictions pertaining to, among other things, maximum
    shareholding, transfer and voting rights. For a description of the
    agreement, see the information found at page 22 hereof under the heading
    "Stockholder Agreement."
 
(3)  HC Investments, Inc., a Delaware corporation, is an indirect, wholly-owned
    subsidiary of Henkel KGaA. Voting shares of the Company beneficially owned
    by HC Investments, Inc. are bound by the terms of the agreement between the
    Company and Henkel KGaA, as described at page 22 hereof.
 
                        SECURITY OWNERSHIP OF MANAGEMENT
 
In general, "beneficial ownership" includes those shares of Common Stock which a
director or officer has the power to vote or transfer, as well as stock options
that are exercisable currently or within 60 days of March 5, 1999. On March 5,
1999, the executive officers and directors of the Company owned, in the
aggregate, 3,292,949 shares of Common Stock which is approximately 2.5% of
shares outstanding. (As required by SEC disclosure rules, "shares outstanding"
for this purpose includes options exercisable within 60 days.) The detail of
beneficial ownership is set forth in the following table. No individual
executive officer or director beneficially owned in excess of 1% of the
outstanding stock.
 
Non-employee directors also have interests in stock units under the Company's
1997 Non-Employee Director Deferred Compensation Plan which was approved by the
Stockholders in May 1997. The stock units are Common Stock equivalents. The
stock units are credited to a deferred stock unit account
 
                                       2
<PAGE>
and will be paid in the form of Common Stock when a director leaves the Board.
Although the stock units may not be voted or transferred, they are shown in the
table below because they represent part of the total economic interest of the
directors in Company stock.

                             ELECTION OF DIRECTORS
 
The business and affairs of the Company are managed under the overall direction
of the Board of Directors. To assist it in carrying out its duties, the Board
has delegated certain authority to four standing committees: Audit,
Compensation, Finance and Governance.
 
There were four meetings of the Board of Directors during the year ended
December 31, 1998. Except for Messrs. Richards and Woeste, each director
attended at least 75% of Board and Committee meetings. Overall attendance at
Board and Committee meetings was 85%.
 
The Audit Committee, currently comprised of Messrs. Howard, Jews, Richards,
Schall (Chairman), Uyterhoeven and Woeste, met four times during the past year.
The Committee, which is comprised
 
                                       3
<PAGE>
entirely of independent directors, assists the Board of Directors in overseeing
management's discharge of its duties for the preparation of interim and annual
financial statements and for maintaining financial control of operations.
Principal responsibilities include (a) oversight of the accuracy of public
financial reports, including review of the plan and scope of the annual audit,
the results of the audit and the independence of the independent accountants,
(b) providing oversight assurance that the Company has an effective system of
internal controls and (c) providing oversight assurance that the Company has
effective controls against employee conflict of interest and fraud and
reasonably complies with related laws. The Committee also recommends to the
Board of Directors with regard to the retention of the Company's independent
accountants. In addition, the Committee assists the Board of Directors in
overseeing the accounting controls and policies and reporting practices of the
Henkel-Ecolab Joint Venture, an entity described at page 21 hereof under the
heading "Certain Transactions" and whose financial statements are filed as a
part of the Company's Annual Report on Form 10-K. The Committee meets regularly
with the Company's management and internal auditors, and with the Company's
independent accountants.
 
The Compensation Committee, currently comprised of Ms. Block and Messrs. Biller
(Chairman), Grundhofer, Johnson and Levin, met four times during the past year.
The Committee is comprised entirely of independent directors. The principal
functions of this Committee are to review and approve (a) the Company's overall
compensation policy and executive salary plan, (b) the base salary of the five
most highly compensated and certain other executive officers, and (c) the
design, amendment, establishment and termination of the Company's employee
benefit plans and related trusts. The Committee also administers the Company's
stock and cash-based incentive plans for executives, and makes recommendations
to the Board with respect to (a) the base salary and other compensation of
officers of the Company who also serve as directors, and (b) the design and
establishment of long-term executive compensation and executive benefit plans.
To assist the Committee in the design and review of executive compensation
programs, the Board has selected and retained an independent compensation
consultant who reports directly to the Committee. A report by the Committee on
executive compensation is located on pages 12 through 15 hereof.
 
The Finance Committee, currently comprised of Ms. Block and Messrs. Jews,
Richards (Chairman), Schall, Schulz, Shannon and Uyterhoeven, met four times
during the past year. The principal functions of this Committee are to review
and make recommendations to the Board concerning (a) the financial condition,
financial policies and standards, and long-range financial objectives of the
Company, (b) the Company's financing requirements, including the evaluation of
management's proposals concerning funding vehicles to meet such requirements,
(c) debt limits, (d) dividends, (e) the Company's capital expenditures budget,
(f) adequacy of insurance coverage and (g) the financial structure and policies
of the Henkel-Ecolab Joint Venture with particular attention to their impact on
the financial condition of the Company. The Committee also evaluates
acquisitions and divestitures of businesses from a financial standpoint. The
Committee oversees a management committee which is charged with monitoring the
performance of trust assets held in the Company's benefit plans.
 
The Governance Committee, currently comprised of Messrs. Biller, Grundhofer,
Howard (Chairman), Johnson, Levin, Schuman, and Woeste, met three times during
the past year. The Governance Committee (a) reviews and recommends to the Board
policies for the composition of the Board, (b) identifies, interviews, evaluates
and recommends to the Board prospective director nominees, (c) reviews and makes
recommendations to the Board with regard to compensation for Board service, (d)
reviews and recommends to the Board changes in the Company's Certificate of
Incorporation and By-Laws, (e) reviews and recommends to the Board with respect
to Board organization, management succession and corporate governance issues,
social responsibility and the Company's environmental practices, (f) leads the
Board's Chief Executive Officer evaluation and Board effectiveness review
processes, and (g) undertakes projects which do not fall within the jurisdiction
of other committees of the Board. Recommendations by stockholders of potential
director nominees may be directed to the Governance Committee in care of the
Secretary of the Company, at the Company address located at the top of page 1.

Under the Company's Restated Certificate of Incorporation, the number of
directors is determined exclusively by the Board. Currently, the Board has fixed
the number of directors at 14.
 
Pursuant to the agreement between the Company and Henkel KGaA described at page
22 hereof under the heading "Stockholder Agreement," Henkel is entitled to
designate a number of persons to be nominated for election to the Company's
Board of Directors proportionate to Henkel's shareholding in the Company rounded
to the nearest whole number. As of March 16, 1999, Henkel beneficially owned
approximately 24.1% of the Company's outstanding Common Stock and was
accordingly entitled to designate three directors. Messrs. Roland Schulz, Hugo
Uyterhoeven and Albrecht Woeste have been appointed or elected to the Board
pursuant to designation by Henkel.
 
The Board of Directors is divided into three classes. The members of each class
are elected to serve a three-year term with the terms of office of each class
ending in successive years.
 
The term of Class I Directors expires with this Annual Meeting of Stockholders.
Messrs. Howard, Levin, Richards, Schall and Schulz are the nominees for election
to the Board as Class I Directors and all have previously served as directors of
the Company. Class I Directors being elected at the current Annual Meeting will
serve until the 2002 Annual Meeting expected to be held in the Spring of 2002,
or until their successors have been duly elected and qualified. The directors of
Class II and Class III will continue in office.
 
The Board of Directors has no reason to believe that any of the named nominees
is not available or will not serve if elected. However, pursuant to the Board of
Directors' policy, a director who becomes 70 years of age must resign at the
next Annual Meeting following such event. Messrs. Richards and Schall will
become 70 prior to next year's Annual Meeting and will be required to resign
effective no later than May 2000, at which time the Board of Directors, pursuant
to the Company's Restated Certificate of Incorporation, may fill one or both of
the vacancies or may reduce the size of the Board for any vacancy not so filled.
 
The directors shall be elected by a plurality of the votes cast. The five
director nominees receiving the highest vote totals will be elected. Shares
represented by proxies which contain instructions to "withhold" voting authority
on one or more nominees will not affect the election of nominees receiving a
plurality of the votes cast. It is intended that proxies solicited by the Board
of Directors will (unless otherwise directed) be voted for the election of the
five nominees named in this Proxy Statement. If, for any reason, any nominee
becomes unavailable for election, the proxies solicited by the Board of
Directors will be voted for such substituted nominee as is selected by the Board
of Directors, or the Board of Directors, at its option, may reduce the number of
directors to constitute the entire Board.
 
The following information with regard to business experience has been furnished
by the respective directors or nominees or obtained from the records of the
Company.

                             EXECUTIVE COMPENSATION
 
         REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION
 
The Compensation Committee (the "Committee") of the Company's Board of Directors
is responsible for the overall executive compensation program and each
component. The Company's management and a compensation consultant provide
competitive data and assistance to help the Committee carry out its
responsibilities. The Board holds authority to ratify certain actions of the
Committee.
 
The Committee reviews each executive compensation component annually to maintain
alignment with the Company's goals and philosophy.
 
PHILOSOPHY:  The Committee uses compensation to help communicate desired
business results to executives, influencing them to make decisions to produce
those results. The program must be competitive to attract, retain and motivate
executives, and it must reinforce and complement sound management practices. In
addition, the executives' interests must be effectively aligned with those of
our shareholders and, to this end, the Committee has developed executive stock
ownership guidelines to ensure that executives accumulate a significant
ownership stake and are vested in maximizing long-term shareholder returns.
 
Each component of the executives' compensation is targeted at the median of a
broad range of United States manufacturing and service companies. This general
industry standard represents a broader index for comparison than the Standard
and Poor's Chemicals (Specialty) Index used in the performance graph on page 19.
The Committee consults a number of general industry surveys which collect a
significant portion of their data from the Standard & Poor's 500 Index or
equivalent companies. The data is adjusted through regression analysis to
reflect the Company's size relative to those companies included in the data.
This size-adjusted data of the "comparator group" of companies is the
information relied upon by the Committee to provide a generally accurate
representation of the relevant competitive market.
 
The overall executive compensation program is designed to deliver median pay for
median Company performance. To the extent the Company's performance exceeds the
general industry median performance, total compensation will also exceed median
levels. Conversely, total compensation will be less than the median if Company
performance falls below the median performance level.
 
COMPONENTS:  The Company's compensation program for executives includes four
components, each of which plays a specific role in the overall total
compensation approach, including:
 
       - Base Salary;
       - Management Incentive Plan or Management Performance Incentive Plan;
       - Long-Term Incentives; and
       - Benefits/Perquisites.
 
    Base Salary:  The Committee's philosophy is to set base salaries at the
    competitive market median, as represented by the comparator group. However,
    individual performance is also taken into account and may result in
    variations from the median. Surveys provide the data needed to determine the
    market median base salary opportunities of the comparator group. The
    Committee reviews the base salary of executive officers on an annual basis
    in light of the market data and the officer's individual performance to
    determine whether an increase in base pay is appropriate. In 1998, executive
    officers' base salary increases averaged 5.9%, excluding promotional
    increases.
 
    The Committee increased Mr. Schuman's base salary by 11.1% effective on
    January 1, 1998. This increase brought Mr. Schuman's base salary to a level
    generally equivalent to the 60(th) percentile of the market. The increase,
    and salary level, reflected the Committee's assessment of Mr. Schuman's
    excellent performance as reflected by the Company's strong financial results
    in 1997.

    Management Incentive Plan (MIP)/Management Performance Incentive Plan
    (MPIP):  The MIP is a cash-based annual incentive plan that focuses
    executives' attention on achieving competitive annual business goals. The
    Committee, with input from management, sets specific performance goals at
    the beginning of each year and communicates them to the Company's
    executives. A mix of corporate and business unit goals is used to assure
    that executives have a reasonable measure of control over the factors
    affecting their awards. The Committee also establishes median awards,
    expressed as a percentage of base salary. The median award is established at
    a level which approximates median annual incentive targets expressed as a
    percentage of base salary of the comparator group. Achievement of median
    performance goals, as established by the Committee, will result in a median
    award, while achievement of performance levels below or above the median
    performance goal will result in minimum, premium or maximum awards.
 
    The MPIP is a shareholder approved plan which is essentially the same as the
    MIP. The MPIP was adopted in response to Section 162(m) of the Internal
    Revenue Code, which disallows deductions by public corporations of certain
    executive compensation in excess of $1,000,000 unless the plan meets certain
    requirements. For 1998, Messrs. Schuman and Shannon were the only
    participants in this plan.
 
    Mr. Schuman and Mr. Shannon earn awards based solely on the achievement of
    Diluted Earnings Per Share (EPS) goals. Other executives with corporate-wide
    responsibility earn awards based 75% on EPS performance and 25% on total
    division operating income goals. The Committee establishes annual EPS levels
    that must be achieved to receive threshold, median and maximum awards.
    Economic projections and the compounded annual EPS growth over three-year
    periods for the Standard & Poor's 500 Index were the basis for the EPS goals
    in 1998.
 
    For executives with business-unit responsibilities, 75% of their MIP award
    is earned by meeting unit-specific operating income goals and 25% is
    dependent on corporate EPS performance. As long as operating income
    thresholds are met by the business unit, other financial or strategic
    factors can also affect the size of the awards. The weight of each
    performance measure varies among business units. In 1998, the average
    weighting of the performance measures for the majority of the business units
    was 44% operating income, 43% sales, and 8% cash flow. The remaining
    performance measures, which fluctuated more greatly among units, included
    measures such as management of working capital items.
 
    The Committee, in general, makes awards based strictly on level of
    achievement against pre-established goals. However, under the MIP, the
    Committee may, in its sole discretion, make awards at a level higher or
    lower than that determined by strict application of achievement against
    goals based upon such other business criteria as the Committee determines
    appropriate.
 
    The award under the MPIP for 1998 performance was $1,050,000 or 150% of base
    salary for Mr. Schuman. The award was based on the Company's 1998 EPS growth
    of approximately 15% over 1997 results, and was derived from the EPS
    performance levels and corresponding cash award levels established by the
    Committee at the beginning of the plan year using the methodology described
    above. Mr. Schuman's potential cash award for 1998, as established by the
    Committee, ranged from a threshold of 26% of base salary to a maximum of
    150% of base salary. Under the MPIP, the Committee is allowed only downward
    discretion in determining the award, and no adjustment was made to the
    award.
 
    Special Recognition Award:  At its February 1999 meeting, the Committee,
    after receiving a completed performance report conducted by the Governance
    Committee on Mr. Schuman's accomplishments and performance in 1998, awarded
    Mr. Schuman a special recognition award of $50,000. This special award,
    together with the award earned under the MPIP, brought total cash awarded as
    annual bonus in respect of 1998 to $1,100,000.
 
    Long-Term Incentives:  The Committee uses grants of stock options and
    restricted stock to deliver a competitive compensation package that
    motivates executives to make decisions that will
 
                                       13
<PAGE>
    increase the value of Company stock, thus providing an appropriate focus on
    the long-term growth of the Company. When executives deliver sustained
    superior returns to shareholders by outperforming the general industry, they
    can increase their own compensation accordingly.
 
    Options are granted with exercise prices not less than the fair market value
    of the Company's shares on the date of grant, providing no value to the
    executive unless the Company's stock price increases after the grants are
    made. The options become exercisable cumulatively at the rate of 25, 50, 75
    and 100% on each anniversary of the date of grant and become exercisable
    earlier upon a Change in Control of the Company as such term is defined in
    footnote 4 to the Summary Compensation Table found at page 16 of this Proxy
    Statement. The options have a term of 10 years.
 
    Restricted stock vests in equal installments on the second and fourth
    anniversary of the grant. The Committee uses restricted stock as a component
    of long-term executive compensation for two reasons: (1) similar to options,
    restricted stock aligns executive pay with shareholder value over the
    long-term; and (2) restricted stock grants provide a retention incentive,
    decreasing the likelihood of costly, disruptive executive turnover.
 
    The Committee's philosophy is to make stock incentive grants at the median
    gain opportunity awarded to executives in similar positions in the
    comparator group. However, individual performance is taken into
    consideration and can result in variations from the median. The grants
    consist primarily of stock options. As to executive officers, restricted
    stock represents between 22% to 43% of the total long-term incentive value
    granted. The mix of restricted shares is set at approximately 20% for Mr.
    Schuman, and increases to an average of 26% for the remaining executive
    officers named in this Proxy Statement. Within a small range of variability,
    this mix between options and restricted shares has been in place for a
    number of years and has proven to be valuable in building alignment with
    shareholders, providing retention incentive, and increasing executive share
    ownership.
 
    On August 14, 1998, the Committee granted to Mr. Schuman options to purchase
    130,000 shares with an exercise price of $29.71875 and a restricted stock
    grant in the amount of 12,500 shares. Mr. Schuman's stock incentives for
    1998 had a gain opportunity which approximated the 65(th) percentile of the
    comparator group. The award level reflected the Committee's assessment of
    Mr. Schuman's excellent performance as reflected by the Company's strong
    financial results in 1997.
 
    Growth Reward Plan:  In 1998, the Company launched a new strategic business
    plan which targets aggressive growth over the next five years. To incent the
    achievement of the growth goals of the plan, the Committee on February 20,
    1998 made a special grant of premium-priced stock options to a select group
    of executives, including Mr. Schuman and eight other executive officers. The
    Committee established the premium exercise price based on the median stock
    price growth rate of the S&P 500 measured over the past 15 years. This
    annualized growth rate, which was 12%, was applied to the price of Company
    stock over a 5-year period and resulted in an exercise price of $49.00. The
    premium exercise price was approximately 75% above the fair market value of
    Company stock on the date of grant and requires that the Company's stock
    price must outperform historic market trends before any value can be
    realized by participants. In addition, the option term was shortened from
    the standard 10 years used by the Committee to 5 years and 3 months to more
    closely correspond with the duration of the strategic plan. The options vest
    100% after 3 years from the date of grant.
 
    Mr. Schuman received 715,000 premium-priced stock options. In determining
    the size of Mr. Schuman's grant, the Committee considered market stock price
    performance trends, future projections for Company financial and stock price
    performance and predictions of future total compensation levels for Mr.
    Schuman relative to the competitive market. Although it is difficult to
    forecast with precision, it was the intent of the Committee to position Mr.
    Schuman's 5-year
 
                                       14
<PAGE>
    annualized total compensation including his anticipated return from the
    premium-priced options at approximately the 75(th) percentile of the market
    if the Company is able to achieve the strategic plan's long-term growth
    goals.
 
    Benefits/Perquisites:  Executive benefits and perquisites are primarily
    attraction and retention tools. They provide protection against the
    financial catastrophes that can result from illness, disability and death.
    They meet basic executive needs, allowing them to focus their attention on
    the Company's business goals. The Company surveys the practices of the
    comparator group and matches its benefits and perquisites to those provided
    by a majority of companies.
 
POLICY WITH RESPECT TO THE $1 MILLION DEDUCTION LIMIT:  Section 162(m) of the
Internal Revenue Code generally limits corporate deduction for compensation paid
to the Chief Executive Officer and the four most highly compensated officers
serving at year end to $1,000,000, unless certain requirements are met. The
Committee's intent is to operate its compensation programs for the executive
officers subject to the deduction limit so the corporate tax deduction is
maximized on compensation paid. However, the Committee will do so only to the
extent practicable, and consistent with the Company's overall compensation
philosophy.
 
The Committee believes that compensation realized from the exercise of stock
options granted under its Stock Incentive Plans and the MPIP Plan (which Plans
have been approved by the stockholders) will be exempt from the $1,000,000 cap
imposed by Section 162(m). However, certain elements of executive compensation
such as base salary, dividends on restricted stock, perquisites and vesting of
restricted stock, are not exempt from the $1 million exemption and may cause a
portion of executive compensation to exceed the deductibility limit.
 
Elsewhere in this Proxy Statement, the Board of Directors is recommending to the
shareholders the extension of the Company's 1997 Stock Incentive Plan and the
adoption of a new Management Performance Incentive Plan. The Committee believes
that adoption of these plans will allow the Company to deduct compensation
arising from these plans pursuant to Section 162(m).
 
CONCLUSION:  The Committee believes that executive compensation policies and
programs described in the report serve the interests of shareholders and the
Company effectively. The various pay vehicles utilized maintain an appropriate
balance between motivating achievement of short-term goals and strategically
leading the Company in a direction to provide long-term success. We will
continue to monitor the effectiveness of the Company's total compensation
program to ensure that it meets the needs of the Company.

(1)  Includes amounts deferred under Section 401(k) of the Internal Revenue
    Code, pursuant to the Company's Savings Plan, amounts deferred under a
    non-qualified deferred compensation plan maintained by the Company for a
    select group of executives and salary reductions per Section 125 of the
    Internal Revenue Code.
 
(2)  Represents annual cash awards under the Company's Management Incentive Plan
    ("MIP") and, if applicable, the Company's Management Performance Incentive
    Plan ("MPIP"). The MIP and MPIP are discussed at page 13 hereof in the
    "Report of the Compensation Committee on Executive Compensation."
 
(3)  Represents payment by the Company of: (i) certain payroll taxes under the
    Company's non-contributory non-qualified supplemental defined benefit plans
    referred to in the text following the "Pension Plan Table" on page 20; and
    (ii) in the case of Mr. Marcantonio, certain relocation expenses ($65,681)
    incurred in 1997 and certain payroll taxes thereon. In addition, the Company
    maintains supplemental long-term disability benefits for a select group of
    executives, which benefits are self-funded. No specific allocation of cost
    is made to any named executive officer prior to the occurrence of a
    disability.
 
(4)  Represents the cumulative dollar value of restricted stock awards during
    the calendar year based on the closing market price of the Company's Common
    Stock on the date of grant. The recipients receive dividends declared on,
    and have voting power over, the restricted shares. The value and number of
    the aggregate shares of restricted stock held by the named executive
    officers at December 31, 1998 were as follows: Mr. Schuman, $2,071,011 with
    57,230 shares; Mr. Shannon, $796,125 with 22,000 shares; Mr. McCarty,
    $487,446 with 13,470 shares; Mr. Marcantonio, $379,444 with 10,500 shares;
    and Mr. Spooner, $394,444 with 10,900 shares.
 
   The restricted stock awards vest on the second and fourth anniversary dates
    of the grant at the cumulative rate of 50% of each award, based on continued
    employment of the recipient. The number of shares awarded during 1998, 1997
    and 1996, respectively, to the named executive
 
                                       16

    officers were: Mr. Schuman, 12,500, 12,000 and 14,000; Mr. Shannon, 5,000,
    6,000 and 14,000; Mr. McCarty, 4,000, 4,000 and 5,000; Mr. Marcantonio,
    2,500 and 8,000; and Mr. Spooner, 2,000, 2,400 and 3,000.
 
   Restrictions will lapse immediately on all restricted stock awards in the
    event of a change in control of the Company. A change in control occurs if:
    (i) a person or group acquires 25% or more of the Company's outstanding
    voting power. However, if the acquisition was approved by the Board of
    Directors, then a change in control occurs at 34% ownership. If the
    acquiring person, prior to becoming a 25% shareholder, has entered into (and
    is in compliance with) a shareholder agreement which imposes limits on the
    person's maximum shareholding, then a change in control occurs only upon
    acquisition of 50% of the Company's voting power; (ii) during the period of
    two consecutive years, individuals who, at the beginning of such a period,
    were members of the Board, cease for any reason to constitute at least a
    majority thereof (unless the election or the nomination for election by the
    Company's stockholders of each new director was approved by a vote of at
    least two-thirds of the directors then still in office who were directors at
    the beginning of the period or whose election or nomination were previously
    so approved); (iii) the stockholders approve a merger or consolidation of
    the Company in which voting securities of the surviving entity will
    represent less than 80% of the Company's voting securities prior to the
    transaction; or (iv) the stockholders of the Company approve a plan of
    complete liquidation or an agreement to sell all or substantially all of the
    Company's assets (hereinafter a "Change in Control of the Company").
 
(5)  Includes, for 1998, certain premium priced stock options identified in the
    table at page 18 hereof which offer no gain to the optionee until the stock
    price exceeds $49.00.
 
(6)  Amounts reported for 1998 represent: (i) the maximum matching contribution
    of $4,800 made by the Company to each of the named executive officers under
    the Company's defined contribution 401(k) Savings Plan available generally
    to all employees; and (ii) the matching contributions made or to be made by
    the Company on base salary and bonus earned in respect of 1998 which the
    executive elected to defer under a non-qualified mirror 401(k) deferred
    compensation plan maintained by the Company for a select group of
    executives, in the following amounts: Mr. Schuman, $49,200; Mr. Shannon,
    $24,150; Mr. McCarty, $12,864; Mr. Marcantonio, $10,838; and Mr. Spooner,
    $8,883.

    incentive plans referenced in footnote 2 above, special recognition awards
    in respect of 1998 and 1997 as follows: Mr. Schuman, $50,000 in 1998 and
    $55,000 in 1997; and Mr. Shannon, $8,000 in 1998 and $8,800 in 1997.
 
(8)  Mr. Marcantonio became an executive officer effective March 3, 1997.

</TABLE>
 
The preceding table shows the estimated annual benefits payable under the
Company's non-contributory qualified defined benefit Pension Plan, the Company's
non-contributory non-qualified defined benefit Mirror Pension Plan and the
Company's Supplemental Executive Retirement Plan (based upon a 15-year period
certain for the supplemental retirement benefit and a straight life annuity for
both the qualified and non-qualified pension benefits) following retirement at
age 65 for sample covered compensation amounts and lengths of plan
participation, without regard to vesting and offsets, if any, for benefits under
the Savings Plan or any predecessor plans and Social Security. At the end of 15
years, payment of amounts attributable solely to the Supplemental Executive
Retirement Plan cease. The amounts shown in the preceding table which are
attributable to the Supplemental Executive Retirement Plan would be reduced by
$8,052, which is the amount attributable to 50% of the primary Social Security
annual retirement benefit, based upon 1998 maximum levels for retirement in 1998
at age 65, and by annuitized amounts presumed to be paid from the Company's
matching contribution made prior to July 1, 1994 under the Company's Savings
Plan and a former profit-sharing plan of the Company.
 
The table does not show the additional "past service benefit" provided under the
Supplemental Executive Retirement Plan to eligible executives who are unable to
earn the maximum supplemental benefit by retirement at or after age 65 because
the executive was hired by the Company after age 35. The past service benefit
would add an additional benefit of 1% of the difference between covered
compensation at retirement and earnings at the time of joining the Company
("first year earnings") for each year by which the executive's age at date of
hire exceeded 35. Messrs. Shannon, Marcantonio and Spooner are currently subject
to these provisions and their first year earnings and estimated years of service
creditable as past service are as follows: Mr. Shannon, $215,682 with 13.12
years; Mr. Marcantonio, $321,233 with 12.85 years; and Mr. Spooner, $365,000
with 12.93 years.
 
Applicable approximate covered compensation and credited years of service as of
December 31, 1998 for the combined pensions and supplemental executive
retirement benefits for the individuals named in the Summary Compensation Table
at page 16 hereof are as follows: Mr. Schuman, $1,050,440 with 41.2 years; Mr.
Shannon, $708,940 with 14 years; Mr. McCarty, $433,380 with 35.9 years; Mr.
Marcantonio, $473,367 with 1 year; and Mr. Spooner, $476,114 with 4 years.
 
Covered compensation is based on the executive officer's average annual earnings
during the five continuous years of highest earnings. In general, there is no
material variation between compensation used to determine covered compensation
and the base salary and bonus compensation of executive officers as reported in
the Summary Compensation Table at page 16 hereof.

DIRECTOR REMUNERATION
 
Members of the Board of Directors who are not employees of the Company are paid
an annual retainer of $22,000 and a fee of $1,200 for each Board or committee
meeting they attend. Committee chairs each receive an additional fee of $4,500
per annum. One-half of the annual retainer amount is paid in the form of stock
units (which are described on pages 2 and 3 hereof).
 
In addition, non-employee directors receive 600 stock units per annum.
 
Under a deferred compensation plan, non-employee directors may elect to defer
some, or all, of the cash portion of their directors fees until cessation of
Board service. Amounts deferred are not subject to federal income tax until
received by the participant and are co-mingled with the Company's general
operating funds. Deferred amounts either earn interest at market rates or are
invested in the stock unit account at the election of the director. Upon
cessation of Board service, deferred amounts (whether in the interest-bearing
account or in the stock unit account) are paid in a lump sum or in equal
installments to a maximum of ten years as elected by the director.
 
Each non-employee director participates in the Company's 1995 Non-Employee
Director Stock Option Plan. Under that Plan, each such director elected at an
annual meeting of stockholders to a full three-year term receives a
non-statutory option to purchase 12,000 shares of Common Stock at the fair
market value of the Common Stock on such date. The option becomes exercisable,
on a cumulative basis, as to 4,000 shares on each of the next three subsequent
annual meetings of stockholders. A director elected or appointed to less than a
full three-year term receives a pro rated grant. In the event a director ceases
to serve due to death or disability, all shares subject to the option become
immediately exercisable.
 
An option may be exercised for a period of ten years from grant. However, in the
event the director ceases to be a director due to death or disability, or for
any other reason, the exercise period is shortened to the lesser of five years
from such date or the expiration of the original term.
 
                              CERTAIN TRANSACTIONS
 
The Company and Henkel KGaA ("Henkel") each have a 50% economic interest in a
joint venture engaged in industrial and institutional cleaning and sanitizing
businesses throughout Europe ("Joint Venture"). Neither partner may transfer its
interest in the Joint Venture without the other's consent. Henkel has a
tie-breaking vote on certain matters pertaining to the continuation of business
during an impasse, which includes appointment of the Joint Venture senior
executives and adoption of the annual business plan. Strategic decisions
concerning the Joint Venture require the agreement of the Company and Henkel.
The Company and Henkel are equally represented on the four member governing
board for the Joint Venture. Mr. Schulz is one of the two Henkel designees on
the governing board. The Company includes the operations of the Joint Venture in
its financial statements using the equity method of accounting and financial
statements of the Joint Venture are included as a part of the Company's Annual
Report on Form 10-K.
 
While the Joint Venture has its own manufacturing, training and research and
development facilities, it also has access to the basic technology of both the
Company and Henkel for which it pays each company an equal royalty based on net
sales. The Joint Venture operates on a stand alone basis but obtains certain
administrative support from Henkel and its affiliates and acquires certain
products from the Company and Henkel as well as from third parties. All such
royalties and prices for administrative services and products are based on arm's
length negotiations. Mr. Schulz is an Executive Vice President of Henkel and Mr.
Woeste is Chairman of the Shareholder's Committee and the Supervisory Board of
Henkel.
 
As part of the 1991 transaction with Henkel in which the Joint Venture was
formed, the Company, as described under the heading "Company Transactions" at
page 22, acquired Henkel businesses in 19 countries outside of Europe. The
Company also acquired options, exercisable through July 11, 2001,
 
                                       21
<PAGE>
to acquire Henkel's interest in cleaning and sanitizing businesses in certain
other countries at formula prices, in general, based on earnings of the
businesses. An option to acquire such businesses remains for Korea.
 
                             STOCKHOLDER AGREEMENT
 
As of March 16, 1999, Henkel KGaA and its affiliates owned approximately 31.24
million shares of the Company's Common Stock as set forth in the table of
Security Ownership of Certain Beneficial Owners located on page 2 hereof.
 
Henkel's equity ownership in the Company is subject to an agreement
("Stockholder's Agreement") containing certain restrictions pertaining to, among
other things, maximum shareholding, transfer and voting rights. Generally, the
Stockholder's Agreement terminates on June 26, 2009. During the year second
preceding such date, Henkel and the Company will commence negotiations for an
extension of the term. If an agreement to extend such term is not reached,
Henkel would have the right, and in certain circumstances the obligation, to
purchase the Company's interest in the Joint Venture (the Joint Venture is
described under the heading "Certain Transactions" at page 21 hereof). The
purchase price shall be paid by Henkel in the Company's Common Stock owned by
it, with any excess price payable in cash. If the value of Henkel's Common Stock
ownership exceeds the purchase price, then the Company may acquire such
remaining Common Stock at market value. After any such purchase, the
Stockholder's Agreement would remain in effect for an additional two years. In
addition, the Stockholder's Agreement provides that if the Joint Venture is
terminated or Henkel owns less than 1% of the Company's Common Stock, the
Stockholder's Agreement will terminate two years after the later of such events.
 
Pursuant to the Stockholder's Agreement, Henkel is precluded from acquiring more
than 26% of the Company's outstanding Common Stock prior to July 11, 2000 and
30% thereafter through the period of the Stockholder's Agreement, or from
acting, alone or in concert with others, to control or influence the Company.
Henkel may sell its shares of the Company's Common Stock under certain
conditions specified in the Stockholder's Agreement subject to the Company's
right of first refusal. In addition, Henkel has agreed to vote its shares, in
the case of election of directors of the Company or certain stockholder
proposals, in accordance with the recommendation or directions of the Board. In
all other cases, except with respect to certain "strategic transactions," Henkel
may vote, at its option, either in accordance with the recommendation of the
Board or pro rata in the same manner and proportion that votes of the
stockholders of the Company (other than Henkel and officers or directors of the
Company) have been cast. Any vote with respect to "strategic transactions"
(among other things, an increase in the authorized shares or an amendment to the
Certificate of Incorporation, as well as a disposition, recapitalization or
dissolution of the Company or other transactions which could have a material
effect upon Henkel's investment in the Common Stock) may be cast at Henkel's
sole discretion. Henkel also is entitled to designate nominees for election to
the Company's Board of Directors proportionate to the percentage of its holding
of voting securities in the Company (rounded to the nearest whole number).
Currently, Henkel has designated for election three of the Company's 14
directors. Those directors are: Roland Schulz, Albrecht Woeste and Hugo
Uyterhoeven. Further information concerning Henkel directorships is found at
page 5 hereof under the heading "Election of Directors."
 
                              COMPANY TRANSACTIONS
 
During 1998, the Company sold products and services in the amount of
approximately $4,760,000 to Henkel or its affiliates, and purchased products and
services in the amount of approximately $3,345,000 from Henkel or its
affiliates. The sales were made at prices comparable to prices charged to other
customers and the Company believes that the amounts paid for products and
services purchased were comparable with prices charged by other suppliers for
similar products.
 
In 1991, as part of the transaction with Henkel in which the Joint Venture was
formed, the Company acquired Henkel's industrial and institutional cleaning and
sanitizing businesses in 19 countries
 
                                       22
<PAGE>
outside of Europe. In addition, pursuant to options granted to the Company by
Henkel as part of the 1991 transaction, and described under the heading "Certain
Transactions" on page 21 hereof, the Company has acquired additional
non-European businesses from Henkel, including in some cases from joint ventures
controlled by Henkel. During 1998, these non-European businesses paid Henkel or
its affiliates approximately $1,036,000 for administrative services and
approximately $2,279,000 for products under supply arrangements. In addition,
the Company received the right, in return for the annual payment of 2.5 million
Deutsche marks (approximately $1,400,000), to have access to certain technology
of Henkel which is relevant to most of the Company's businesses. The payment
obligation has been extended to continue until July 1, 2000 and was determined
through arm's length negotiation.
 
During calendar 1998, a subsidiary of the Company purchased a manufacturing
facility and real estate in Tanzania from Henkel for approximately $570,000.
Separately, the Company sold the Maxwell Automotive business to an Australian
subsidiary of Henkel for A$8,600,000 (approximately $5,400,000). Maxwell
Automotive was a unit of Gibson Chemical Industries Limited which the Company
acquired in a public tender offer in late 1997. The divestiture of Maxwell
Automotive was one in a series of dispositions of "non-core" Gibson businesses
and was sold to the Henkel subsidiary in an arm's length transaction after
soliciting offers from other potential buyers. The portion of the Gibson
purchase price allocated to the Maxwell Automotive business was substantially
equivalent to the sales price.
 
          PROPOSAL TO AMEND AND RESTATE THE 1997 STOCK INCENTIVE PLAN
 
INTRODUCTION AND REASONS FOR AMENDMENTS
 
The Company's 1997 Stock Incentive Plan (the "1997 Plan") was adopted by the
Board of Directors on December 20, 1996, and was approved by the Company's
stockholders on May 9, 1997. The 1997 Plan provides for awards to eligible
recipients of (i) options to purchase Common Stock that qualify as "incentive
stock options" ("Incentive Options") within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"); (ii) options to purchase
Common Stock that do not qualify as Incentive Options ("Non-Statutory Options");
(iii) awards of shares of Common Stock that are subject to certain forfeiture
and transferability restrictions ("Restricted Stock Awards"); and (iv) awards of
Common Stock which are not subject to forfeiture provisions but which may, but
need not be, subject to certain other conditions ("Performance Stock Awards").
Incentive Options and Non-Statutory Options are collectively referred to herein
as "Options," and Options, Restricted Stock Awards and Performance Stock Awards
are collectively referred to herein as "Incentive Awards."
 
The 1997 Plan (as adjusted for the Company's January 15, 1998 2-for-1 stock
split) currently provides for the issuance of up to 6,000,000 shares of Common
Stock pursuant to Incentive Awards.
 
On February 19, 1999, the Board of Directors approved an amendment and
restatement of the 1997 Plan, including amendments to (i) reserve an additional
6,000,000 shares of Common Stock for issuance pursuant to Incentive Awards, (ii)
extend the term of the 1997 Plan by two years, until June 30, 2005 and (iii)
increase the number of shares of Common Stock covered by Options (or other
Incentive Awards with a value based solely on an increase in the value of Common
Stock after grant), which may be granted in any 48-month period to any one
participant from 1,600,000 shares to 2,500,000 shares. The Board's reasons for
these amendments are as follows:
 
    - Of the 6,000,000 shares initially authorized for issuance under the 1997
      Plan, 4,568,660 shares had been issued or made subject to outstanding
      Incentive Awards as of the date of the Board's action. This left only
      1,431,340 shares available for issuance under the 1997 Plan. The proposed
      increase in the number of shares for the 1997 Plan is necessary to permit
      the Company to continue the operation of the 1997 Plan after the remaining
      1,431,340 shares are utilized.
 
    - The proposed extension of the term of the 1997 Plan will allow the Company
      an additional period of time to grant Incentive Awards covering the
      additional shares.
 
                                       23
<PAGE>
    - The increase in the number of shares of Common Stock which may be covered
      by Incentive Awards granted to any participant in any 48-month period will
      provide the Company with greater flexibility to grant Incentive Awards to
      those participants to whom Section 162(m) of the Code applies. Section
      162(m) of the Code requires, among other things, that, the applicable Plan
      contain a per-participant maximum limit in order to ensure tax
      deductibility for certain Incentive Awards.
 
The restatement of the 1997 Plan, including these amendments, is subject to
approval by the Company's stockholders at the 1999 Annual Meeting.
 
PURPOSE
 
The purpose of the 1997 Plan, and of the Plan as proposed to be amended and
restated, is to enable the Company to attract and retain persons of ability by
providing an incentive to such individuals through equity participation in the
Company and by rewarding individuals who contribute to the Company's achievement
of its economic objectives.
 
SUMMARY OF THE AMENDED AND RESTATED 1997 PLAN
 
The major features of the 1997 Plan, as proposed to be amended and restated, are
summarized below. The summary is qualified in its entirety by reference to the
full text of the amended and restated 1997 Plan, a copy of which may be obtained
from the Company. References to the "Restated Plan" shall mean such Plan as
proposed to be amended and restated.
 
GENERAL.  All employees (including officers and directors who are also
employees), and non-employee consultants and advisors of the Company or any
subsidiary of the Company, who, in the judgment of the Committee, have
contributed, are contributing or are expected to contribute to the achievement
of economic objectives of the Company or its subsidiaries are eligible to
participate in the Restated Plan, except that Incentive Options may not be
granted to non-employees.
 
Subject to equitable adjustment due to a Capitalization Change as described
below, the maximum number of shares of Common Stock authorized for issuance
pursuant to the Restated Plan is 12,000,000, of which 4,568,660 have been
already issued or made subject to existing Incentive Awards as of March 5, 1999.
Shares that are issued under the Restated Plan or that are subject to
outstanding Incentive Awards will reduce the maximum number of shares remaining
available for use under the Restated Plan. Any shares of Common Stock that are
subject to an Incentive Award that lapses, expires, is forfeited or for any
reason terminates unexercised or unvested and any shares of Common Stock that
are subject to an Incentive Award that is settled or paid in cash or any other
form other than shares of Common Stock, will automatically again become
available for issuance under the Restated Plan. Any shares of Common Stock that
constitute the forfeited portion of a Restricted Stock Award, will not, however,
become available for further use under the Restated Plan.
 
In the event of any reorganization, merger, recapitalization, stock dividend,
stock split, divestiture or extraordinary dividend or any other change in the
corporate structure or Common Stock of the Company ("Capitalization Change"),
the Restated Plan provides that appropriate equitable adjustment will be made as
to the number and kind of securities available for issuance under the Restated
Plan and, in order to prevent dilution or enlargement of the rights of
Participants, the number, kind and, where applicable, the exercise price of
securities subject to outstanding Incentive Awards.
 
ADMINISTRATION.  The Restated Plan provides for administration by the Board or
by a committee of the Board consisting of not less than two members of the
Board, all of whom are "non-employee directors" within the meaning of Rule 16b-3
under the Exchange Act, and, if the Board so determines in its sole discretion,
who are "outside directors" within the meaning of Section 162(m) of the Code.
The Board of Directors or committee, if established, are referred to herein as
the "Committee." The Board of Directors has appointed its Compensation Committee
as this Committee.
 
In accordance with and subject to the terms of the Restated Plan, the Committee
has the authority to select the recipients of Incentive Awards ("Participants")
and to determine all provisions of any
 
                                       24
<PAGE>
Incentive Award, including the nature and extent of the Incentive Award, the
time or times of grant, the duration of each Incentive Award, and the
restrictions and other conditions to which the payment or vesting of Incentive
Awards may be subject. In addition, the Committee has the authority to pay the
economic value of any Incentive Award in the form of cash, Common Stock or any
combination of both.
 
The Committee has the further authority to amend or modify the terms of any
outstanding Incentive Awards in any manner, provided the amended or modified
terms are permitted by the Restated Plan as then in effect. The Committee may
also accept the surrender of an outstanding Incentive Award and substitute a new
Incentive Award.
 
Unless terminated earlier, the Restated Plan will terminate at midnight on June
30, 2005. Incentive Awards outstanding at the time the Restated Plan is
terminated may continue to be exercised, or become free of restriction, in
accordance with their terms. The Board may suspend or terminate the Restated
Plan or any portion thereof at any time.
 
The Board may amend the Restated Plan from time to time in such respects as it
may deem advisable; provided, however, that no amendments will be effective
without the approval of the Company's stockholders if such approval is then
required pursuant to Section 422 of the Code or the rules of the New York Stock
Exchange. No termination, suspension or amendment of the Restated Plan may
adversely affect any outstanding Incentive Award without the consent of the
affected Participant. No right or interest in any Incentive Award may be
assigned or transferred by a Participant, except by will or the laws of descent
and distribution, or subjected to any lien or otherwise encumbered.
 
OPTIONS.  The Option exercise price may not be less (but may be higher) than
100% of the Fair Market Value of one share of Common Stock on the date of grant.
"Fair Market Value" means the average of the reported high and low sale prices
of the Common Stock quoted in THE WALL STREET JOURNAL as of a specified date.
 
No Participant in the Restated Plan may be granted any Options (or any other
Incentive Awards with a value based solely on an increase in the value of the
Common Stock after the date of grant), relating to more than 2,500,000 shares of
Common Stock in the aggregate during any 48-month period (subject to adjustment
in the event of a Capitalization Change, as set forth above).
 
Payment of an option exercise price may be made either in cash or by tender of
shares of Common Stock (either previously owned by the Participant or to be
acquired upon Option exercise), by delivery of a broker exercise notice
(pursuant to which the broker or dealer is irrevocably instructed to sell enough
shares or loan the optionee enough money to pay the exercise price and to remit
such sums to the Company) or by a combination of such methods. Such payment
shall be subject to the right of the Committee to reject a Participant's
election to pay the option exercise price with previously acquired shares or
pursuant to a broker exercise notice and the Committee may permit the tender of
previously-acquired shares by attestation.
 
Options may be exercised in whole or in installments, as determined by the
Committee in its sole discretion and the Committee may impose conditions or
restrictions to the exercisability of an Option as it determines. Except as
provided below under the heading "Effect of Termination of Employment or Other
Service," an Option will terminate if a Participant's employment or service to
the Company is terminated. In no event may an Option be exercised more than 10
years after its date of grant nor, except for the death or disability of the
Participant, may the Option be exercisable prior to six months from its date of
grant.
 
RESTRICTED STOCK AWARDS.  A Restricted Stock Award is an award of Common Stock
that vests at such times and in such installments as may be determined by the
Committee in its sole discretion and, until it vests, is subject to restrictions
on transferability and the possibility of forfeiture. The Committee may also
impose restrictions or conditions to the vesting of Restricted Stock Awards as
it determines. No Restricted Stock Award may vest prior to six months from its
date of grant except in the event of death or disability of the Participant.
 
                                       25
<PAGE>
Unless the Committee determines otherwise, any dividends (other than regular
quarterly cash dividends) or distributions paid with respect to shares of Common
Stock subject to the unvested portion of a Restricted Stock Award will be
subject to the same restrictions as the shares to which such dividends or
distributions relate.
 
PERFORMANCE STOCK AWARDS.  A Performance Stock Award is an award of Common Stock
that is not subject to risk of forfeiture. A Performance Stock Award may be
awarded on such terms and conditions as the Committee may specify, and may be
granted with or without restrictions on transferability on the underlying Common
Stock.
 
CHANGE IN CONTROL OF THE COMPANY.  In the event a Change in Control of the
Company occurs, then, if approved by the Committee in its sole discretion either
at the time of the grant of the Incentive Award or at any time after such grant,
all Options that have been outstanding for at least six months will become
immediately exercisable in full and will remain exercisable for the remainder of
their terms; all outstanding Restricted Stock Awards that have been outstanding
for at least six months will become immediately fully vested and
non-forfeitable; and any transfer restrictions with respect to Performance Stock
Awards will lapse. In addition, the Committee in its sole discretion may
determine that some or all Participants holding outstanding Options will receive
cash in an amount equal to the excess of the Fair Market Value of such shares
immediately prior to the effective date of such Change in Control over the
exercise price per share of the Options.
 
For purposes of the Restated Plan, a "Change in Control of the Company" has the
meaning given it in footnote 4 to the Summary Compensation Table found on page
16 of this Proxy Statement.
 
EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.  If a Participant ceases
to be employed by the Company and all subsidiaries ("Termination of
Employment"), all Incentive Awards held by the Participant will be modified by
operation of the Restated Plan in the manner set forth below unless otherwise
modified by the Committee in its discretion as set forth below.
 
Upon Termination of Employment due to death or disability, all outstanding
Options then held by the Participant will become immediately exercisable in full
and will remain exercisable for a period of five years (but in no event after
the expiration date of the Option), all Restricted Stock Awards then held by the
Participant will become fully vested and any assignment or transfer restrictions
with respect to outstanding Performance Stock Awards will lapse.
 
Upon Termination of Employment due to retirement, all outstanding Options then
held by the Participant will remain exercisable in full to the extent
exercisable as of such termination for a period of five years after such
retirement (but in no event after the expiration date of any such Option), all
unvested Restricted Stock Awards then held by the Participant will be terminated
and forfeited, and any assignment or transfer restrictions with respect to
Performance Stock Awards that have not lapsed will continue in effect in
accordance with their terms unless otherwise provided in the award agreement.
 
Upon Termination of Employment for any other reason, all rights of the
Participant under the Restated Plan and any award agreements will immediately
terminate except (i) any assignment or transfer restrictions with respect to
Performance Stock Awards that have not lapsed will continue in effect in
accordance with their terms unless otherwise provided in the award agreement and
(ii) all outstanding Options then held by the Participant will remain
exercisable to the extent exercisable as of such termination for a period of
three months thereafter (but in no event after the expiration date of any such
Option). A non-employee consultant or advisor will not be deemed to have
incurred a Termination of Employment if he or she moves directly from the status
of consultant or advisor to that of an employee of the Company or a subsidiary.
 
The Committee may at any time, including following Termination of Employment or
other service, cause (i) Options held by the Participant to become or continue
to become exercisable, and (ii) Restricted Stock Awards and Performance Stock
Awards to vest or continue to vest or become free of restrictions following
Termination of Employment. However, no Incentive Award may be modified to
 
                                       26
<PAGE>
remain exercisable or continue to vest for a period ending the earlier of the
expiration date of the Incentive Award or two years beyond the date the
Incentive Award would have terminated but for the extension.
 
Additionally, if the Committee shall determine that a Participant has committed
certain acts which constitute "Cause," either before or after Termination of
Employment, all rights of the Participant under the Plan or any agreement
evidencing an Incentive Award shall terminate. In general, "Cause,' as defined
in the Restated Plan, means a serious unlawful or criminal act, dishonesty,
fraud or deliberate injury related to the Company, intentional breach of a
material duty to the Company or a material breach of an employment,
confidentiality, or noncompete agreement with the Company.
 
FEDERAL INCOME TAX CONSEQUENCES
 
The following description of federal income tax consequences is based on current
statutes, regulations and interpretations. The description does not include
state or local income tax consequences. In addition, the description is not
intended to address specific tax consequences applicable to an individual
Participant who receives an Incentive Award.
 
INCENTIVE OPTIONS.  There will not be any federal income tax consequences to
either the Participant or the Company as a result of the grant to an employee of
an Incentive Option under the Restated Plan. The exercise by a Participant of an
Incentive Option also will not result in any federal income tax consequences to
the Company or the Participant, except that (i) an amount equal to the excess of
the fair market value of the shares acquired upon exercise of the Incentive
Option, determined at the time of exercise, over the amount paid for the shares
by the Participant will be includable in the Participant's alternative minimum
taxable income for purposes of the alternative minimum tax, and (ii) the
Participant may be subject to an additional excise tax if any amounts are
treated as excess parachute payments (see explanation below). Special rules will
apply if previously acquired shares of Common Stock are permitted to be tendered
in payment of an Option exercise price.
 
If the Participant disposes of the Incentive Option shares acquired upon
exercise of the Incentive Option, the federal income tax consequences will
depend upon how long the Participant has held the shares. If the Participant
does not dispose of the shares within two years after the Incentive Option was
granted, or within one year after the Participant exercised the Incentive Option
and the shares were transferred to the Participant, then the Participant will
recognize a capital gain or loss. The amount of the capital gain or loss will be
equal to the difference between (i) the amount the Participant realized on
disposition of the shares, and (ii) the option price at which the Participant
acquired the shares. Whether the gain or loss constitutes long or short-term
capital gain or loss will depend upon the length of time the Participant held
the stock prior to its disposition. The Company is not entitled to any
compensation expense deduction under these circumstances.
 
If the Participant does not satisfy both of the above holding period
requirements (a "disqualifying disposition"), then the Participant will be
required to report as ordinary income, in the year the Participant disposes of
the shares, the amount by which the lesser of (i) the fair market value of the
shares at the time of exercise of the Incentive Option or (ii) the amount
realized on the disposition of the shares, exceeds the option price for the
shares. The Company will be entitled to a compensation expense deduction in an
amount equal to the ordinary income includable in the taxable income of the
Participant. This compensation income may be subject to withholding. The
remainder of the gain recognized on the disposition, if any, or any loss
recognized on the disposition, will be treated as long-term or short-term
capital gain or loss, depending on the holding period.
 
NON-STATUTORY OPTIONS.  Neither the Participant nor the Company incurs any
federal income tax consequences as a result of the grant of a Non-Statutory
Option. Upon exercise of a Non-Statutory Option, a Participant will recognize
ordinary income, subject to withholding, on the date of exercise in an amount
equal to the difference between (i) the fair market value of the shares
purchased, determined on the date of exercise, and (ii) the consideration paid
for the shares. The Participant may be
 
                                       27
<PAGE>
subject to an additional excise tax if any amounts are treated as excess
parachute payments (see explanation below). Special rules will apply if
previously acquired shares of Common Stock are permitted to be tendered in
payment of an Option exercise price.
 
At the time of a subsequent sale or disposition of any shares of Common Stock
obtained upon exercise of a Non-Statutory Option, any gain or loss will be a
capital gain or loss. Whether the gain or loss constitutes long or short-term
capital gain or loss will depend upon the length of time the Participant held
the stock prior to its disposition.
 
In general, the Company will be entitled to a compensation expense deduction in
connection with the exercise of a Non-Statutory Option for any amounts
includable in the taxable income of the Participant as ordinary income, provided
the Company complies with any applicable withholding requirements.
 
RESTRICTED STOCK AWARDS.  With respect to shares issued pursuant to a Restricted
Stock Award that are subject to a substantial risk of forfeiture, a Participant
may file an election under Section 83(b) of the Code within 30 days after the
shares are transferred to include as ordinary income in the year of transfer an
amount equal to the fair market value of the shares received on the date of
transfer (determined as if the shares were not subject to any risk of
forfeiture). The Company will receive a corresponding tax deduction, provided
that proper withholding is made. If a Section 83(b) election is made, the
Participant will not recognize any additional income when the restrictions on
the shares issued in connection with the stock award lapse. At the time any such
shares are sold or disposed of, any gain or loss will be treated as long-term or
short-term capital gain or loss, depending on the holding period from the date
of receipt of the Restricted Stock Award.
 
A Participant who does not make a proper Section 83(b) election will recognize
ordinary income at the time of the lapse of the restrictions in an amount equal
to the then fair market value of the shares. The Company will receive a
corresponding tax deduction, provided that proper withholding is made. At the
time of a subsequent sale or disposition of any shares of Common Stock issued in
connection with a Restricted Stock Award as to which the restrictions have
lapsed, any gain or loss will be treated as long- term or short-term capital
gain or loss, depending on the holding period from the date the restrictions
lapse.
 
PERFORMANCE STOCK AWARDS.  With respect to shares issued pursuant to a
Performance Stock Award, a Participant will include as ordinary income in the
year of receipt an amount equal to the fair market value of the shares received
as of the date of receipt. The Company will receive a corresponding tax
deduction, provided that proper withholding is made. At the time of a subsequent
sale or disposition of any shares of Common Stock issued in connection with a
Performance Stock Award, any gain or loss will be treated as long-term or
short-term capital gain or loss, depending on the holding period from the date
the shares were received.
 
EXCISE TAX ON PARACHUTE PAYMENTS.  The Code also imposes a 20% excise tax on the
recipient of "excess parachute payments," as defined in the Code and denies tax
deductibility to the Company on excess parachute payments. Generally, parachute
payments are payments in the nature of compensation to employees of a company
who are officers, stockholders, or highly-compensated individuals, which
payments are contingent upon a change in ownership or effective control of the
company, or in the ownership of a substantial portion of the assets of the
company. For example, acceleration of the exercisability of Options, or the
vesting of Restricted Stock Awards, upon a Change in Control of the Company may
constitute parachute payments, and in certain cases, "excess parachute
payments."
 
INCENTIVE AWARDS UNDER THE 1997 PLAN
 
The following table shows the Option grants made through March 16, 1999 under
the current 1997 Plan for those individuals and groups for whom disclosure is
required by the rules of the Securities and Exchange Commission. The Fair Market
Value of the Common Stock on March 16, 1999 was $39.8125.

Neither the number or types of any future Incentive Awards to be received by or
allocated to other particular participants or group of participants under the
Restated Plan is presently determinable. However, no Participant may receive
Options, or any other Incentive Awards with a value based solely on an increase
in the value of Common Stock after the date of grant, relating to more than
2,500,000 shares of Common Stock in the aggregate during any 48-month period
(subject to equitable adjustment in the event of a Capitalization Change).
 
BOARD OF DIRECTORS RECOMMENDATION
 
The Board of Directors recommends that the stockholders vote FOR approval of the
Restated Plan. The affirmative vote of a majority of the total votes cast by the
holders of shares present in person or represented by proxy at the Annual
Meeting and entitled to vote is necessary for approval. In accordance with the
By-Laws of the Company, shares represented by a limited proxy (i.e., a broker
non-vote) or represented by a proxy with instructions to abstain will not be
counted as a vote cast for purposes of calculating votes for or against approval
of these amendments to the Restated Plan. Unless a contrary choice is specified,
proxies solicited by the Board of Directors will be voted FOR approval of the
amendments. In the event that the amendments to the Restated Plan are not
approved by the Company's stockholders, the Company will continue to administer
the 1997 Plan according to its current terms.
 
                        PROPOSAL TO ADOPT THE COMPANY'S
                     MANAGEMENT PERFORMANCE INCENTIVE PLAN
 
INTRODUCTION
 
On February 19, 1999, the Board of Directors adopted, subject to stockholder
approval, the 1999 Ecolab Inc. Management Performance Incentive Plan (the "1999
Plan"), effective for the Plan Year
 
                                       29
<PAGE>
beginning January 1, 1999. The purpose of the 1999 Plan is to assist the Company
in attracting and retaining key executives by focusing such executives on
pre-established, objective performance goals and by providing them the
opportunity to earn financial rewards based on the achievement of such goals.
 
The 1999 Plan will remain in effect through and including the Plan Year ending
December 31, 2003 but may be terminated at any time by the Board of Directors.
Any payments pursuant to awards outstanding upon the termination of the 1999
Plan may be made after termination. A "Plan Year" is the Company's fiscal year.
A general description of the 1999 Plan is outlined below.
 
The 1999 Plan is being submitted to stockholders for approval to obtain the
benefits of federal tax legislation that, while generally disallowing deductions
by public corporations of certain executive compensation in excess of
$1,000,000, permits deduction if, among other things, the plan under which such
compensation is paid has been approved by stockholders. The Company has had a
substantially similar plan in place which was approved by the stockholders on
May 13, 1994. That Plan expired pursuant to its terms effective with the Plan
Year ended December 31, 1998.
 
SUMMARY OF PLAN
 
Awards granted under the 1999 Plan will provide for a cash payment to be made to
participants solely on account of the attainment of one or more pre-established,
objective Performance Goals. Each Performance Goal will consist of Performance
Criteria, which will be one or more objectively determinable measures related to
individual, business unit or Company performance, and a Performance Target which
is the level (expressed as threshold, maximum and intermediate targets) at which
the relevant Performance Criteria must be achieved for purposes of determining
whether a cash payment is to be made under an award. For purposes of the 1999
Plan, the committee administering the 1999 Plan may chose Performance Criteria
from among one or more of the following measures:
 
    - Diluted Earnings Per Share ("EPS") which is net income or loss per share,
      diluted, as reported in the Company's audited year-end consolidated
      statement of income for the Plan Year ("Income Statement");
 
    - Operating Income as reported or included in the Income Statement;
 
    - Net Sales as reported or included in the Income Statement;
 
    - Days Sales Outstanding ("DSO") which is the 12 point average of month-end
      DSO based on monthly performance for days sales invested in accounts
      receivable;
 
    - Capital Expenditures as reported or included in the Company's year-end
      audited consolidated statement of cash flows for the Plan Year;
 
    - Inventory Days on Hand ("DOH") which is the average of 12 month-end DOH
      numbers based on month-end inventory and divided by monthly cost of goods;
 
    - Controllable Expenses which are those expenses under the control of the
      Participant;
 
    - Return on Beginning Equity which is net income divided by beginning of the
      year "shareholder's equity" as reported or included in the Company's
      year-end audited balance sheet for the Plan Year; and
 
    - Return on Net Assets which is (x) Operating Income less income taxes at
      the applicable rate divided by (y) total assets, less cash and cash
      equivalents, investments in securities and non-interest bearing
      liabilities as reported or included in the Company's year-end audited
      financial statements for the Plan Year.
 
Except for EPS (which applies to the consolidated Company) the measurements may
be applied to the Company or, by allocation, to any division or unit thereof.
 
The 1999 Plan will be administered by a committee (the "Committee") appointed by
the Board of Directors consisting of two or more members, each of whom is an
"outside director" within the
 
                                       30
<PAGE>
meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"). The Committee has the authority (i) to select the participants under
the 1999 Plan, (ii) to establish the terms of the awards, (iii) to determine the
time or times when awards will be granted, and (iv) to establish restrictions
and other conditions of the awards. The Committee does not have the authority to
amend or modify the terms of outstanding awards, but shall in the event of (a)
changes in the Company's Common Stock, or any acquisitions or disposition of a
significant business or a significant amount of assets (b) changes resulting
from the accounting effects of discontinued operation, extraordinary income or
loss, changes in accounting and restatement of earnings or (c) non-recurring or
restructuring charges or credits or similar unusual items reflected on the
Company's audited statement of income, adjust awards so that the Performance
Goals following such event are substantially the same as prior to the event. In
all events, the Committee may reduce or eliminate the compensation or other
economic benefit due pursuant to an award.
 
All executive officers of the Company (within the meaning of Rule 3b-7 under the
Securities Exchange Act of 1934) are eligible to participate in the 1999 Plan.
Currently, the Company has 11 executive officers. Participants in the 1999 Plan
will be those eligible executive officers who are selected by the Committee to
receive awards for a Plan Year, or if the executive officer is hired during the
Plan Year, for a portion of the Plan Year.
 
Not later than 90 days after the commencement of a Plan Year (or such earlier
date, as may be required by Section 162(m) of the Code), the Committee will
determine in writing for each participant the Performance Goal(s) for the
participant, including in each case one or more of the Performance Criteria and
the Performance Target for each Performance Criteria, the relative weight
assigned to each Performance Goal and the cash award to be received by the
participant to the extent such Performance Goals are achieved. The cash award
will be expressed as threshold, maximum and intermediate percentages of the base
salary for the participant for the Plan Year, and will range from 10% to 250% of
such base salary. In no event, however, may a participant receive more than
$2,500,000 pursuant to an award for any Plan Year.
 
An individual who is first hired as an executive officer after the inception of
the Plan Year may be selected as a participant by the Committee. In that case,
the Executive Officer will be assigned (within the time periods permitted by
Section 162(m) of the Code) Performance Goals and cash award targets expressed
as a percentage of base salary for the portion of the Plan Year for which the
individual is a participant in the 1999 Plan.
 
As soon as practicable after the end of the Plan Year, and after the Committee
has received the appropriate financial and other data, the Committee will, for
each participant, certify in writing the extent to which the applicable
Performance Goals for the participant have been met and the corresponding amount
of the award earned by the participant. Payment of each award in a cash lump
sum, less applicable withholding taxes, will be made as soon as practicable
thereafter. If the Committee determines that there is a reasonable likelihood
that any compensation paid would not be deductible by the Company by reason of
the limitations under Section 162(m) of the Code, the Committee may defer all or
a portion of the amounts otherwise payable to ensure that the entire amount of
any distribution is deductible, and any deferred amounts may be accompanied by
interest at a reasonable rate.
 
For the Plan Year ending December 31, 1999, the Compensation Committee of the
Company's Board of Directors has selected Allan L. Schuman, President and Chief
Executive Officer of the Company, and Michael E. Shannon, Chairman of the Board,
Chief Financial and Administrative Officer, as the participants.
 
The following table illustrates the maximum cash award Messrs. Schuman and
Shannon may receive under the 1999 Plan for the Plan Year ending December 31,
1999.

In the event of a participant's termination of employment during a Plan Year,
the Committee may (after completion of the Plan Year) cause the payment of all,
or a portion of, the amount earned according to the terms of the award pro rated
for the portion of the Plan Year through the participant's termination.
 
Nothing in the 1999 Plan modifies, rescinds or creates any future limitation on
the Company's power or authority to adopt such additional or other compensation
arrangements as the Board of Directors or a Committee thereof may deem necessary
or appropriate.
 
The Board of Directors may suspend or terminate the 1999 Plan or any portion at
any time and may amend the 1999 Plan in any respect the Board may deem to be in
the best interests of the Company, provided that no amendment shall be effective
without the approval of the stockholders of the Company if such approval of the
amendment is then required for the 1999 Plan to continue to qualify as a
performance-based compensation plan pursuant to Section 162(m) of the Code.
 
BOARD OF DIRECTORS' RECOMMENDATION
 
The Board of Directors recommends that the stockholders vote FOR approval of the
1999 Plan. The affirmative vote of a majority of the total votes cast by the
holders of shares present in person or represented by proxy at the Annual
Meeting and entitled to vote is necessary for approval. In accordance with the
By-Laws of the Company, shares represented by a limited proxy (i.e., a broker
non-vote) or represented by a proxy with instructions to abstain as to this
matter will not be counted as a vote cast for purposes of calculating votes for
or against adoption of the 1999 Plan. Unless a contrary choice is specified,
proxies solicited by the Board of Directors will be voted FOR approval of the
1999 Plan.
 
In the event the 1999 Plan is not approved by the stockholders, the Board will
not implement the 1999 Plan.
 
             RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS
 
Upon the recommendation of its Audit Committee, the Board of Directors has
appointed PricewaterhouseCoopers LLP as independent accountants to audit the
consolidated financial statements of the Company for the year ending December
31, 1999 and to perform other appropriate audit, accounting and consulting
services. Effective July 1, 1998, Price Waterhouse LLP and Coopers & Lybrand
L.L.P. merged to form PricewaterhouseCoopers LLP. Representatives of
PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting of
Stockholders. They will have an opportunity to make a statement if they desire
to do so, and are expected to be available to respond to appropriate questions.
 
Under the laws of the State of Delaware, stockholder ratification of the
appointment of independent accountants is not required. However, the Company
deems it advisable to submit the appointment of PricewaterhouseCoopers LLP for
stockholder consideration and ratification.
 
The Board of Directors recommends a vote FOR the ratification of the appointment
of PricewaterhouseCoopers LLP as independent accountants for the Company. The
affirmative vote of the majority of the total votes cast by holders of shares
present in person or represented by proxy at the Annual Meeting and entitled to
vote shall constitute ratification. In accordance with the By-Laws of the
Company, abstentions will not be counted as votes cast for purposes of
calculating votes for or against
 
                                       32
<PAGE>
ratification of the appointment of PricewaterhouseCoopers LLP. Unless a contrary
choice is specified, proxies solicited by the Board of Directors will be voted
FOR ratification of the appointment. If the appointment is not ratified, the
Board of Directors will reconsider the matter.
 
                                 OTHER MATTERS
 
FUTURE STOCKHOLDER PROPOSALS--DEADLINE FOR INCLUSION IN PROXY
 
Any stockholder proposal to be considered by the Company for inclusion in the
Proxy Statement and form of proxy for next year's Annual Meeting of
Stockholders, expected to be held in May, 2000, must be received by the
Secretary of the Company at the Company's principal executive offices located at
the address found at the top of page 1, no later than December 1, 1999.
 
OTHER STOCKHOLDER PROPOSALS/DIRECTOR NOMINATIONS--DEADLINE FOR CONSIDERATION
 
Stockholder proposals not included in a proxy statement for an Annual Meeting as
well as proposed stockholder nominations for the election of directors at an
annual meeting must each comply with advance notice procedures set forth in the
By-Laws of the Company in order to be properly brought before that Annual
Meeting of Stockholders. In general, written notice of a stockholder proposal or
a director nomination must be delivered to the Secretary of the Company not less
than 90 days nor more than 135 days prior to the anniversary date of the
preceding Annual Meeting of Stockholders. With regard to next year's Annual
Meeting of Stockholders, expected to be held in May, 2000, the written notice
must be received between December 29, 1999 and February 12, 2000 inclusive.
 
In addition to timing requirements, the advance notice provisions of the By-laws
contain informational content requirements which must also be met. A copy of the
By-Law provisions governing these timing procedures and content requirements may
be obtained by writing to the Secretary of the Company.
 
If the presiding officer of the Annual Meeting of Stockholders determines that
business, or a nomination, was not brought before the meeting in accordance with
the By-Law provisions such business shall not be transacted or such defective
nomination shall not be accepted.
 
DISCRETIONARY VOTING
 
As of the date of this Proxy Statement, the Board of Directors and management
know of no other matters to be brought before the meeting in addition to those
described herein. Should any other matters properly come before the meeting
which calls for vote of the stockholders, the persons named in the accompanying
Proxy will have discretionary authority to vote all Proxies with respect to such
matters in accordance with their best judgment.

3.   PLAN ADMINISTRATION.

     3.1  THE COMMITTEE.  The Plan will be administered by the Board or by a
committee of the Board.  So long as the Company has a class of its equity
securities registered under Section 12 of the Exchange Act, any committee
administering the Plan will consist solely of two or more members of the Board
who are "non-employee directors" within the meaning of Rule 16b-3 under the
Exchange Act and, if the Board so determines in its sole discretion, who are
"outside directors" within the meaning of Section 162(m) of the Code.  Such a
committee, if established, will act by majority approval of the members
(unanimous approval with respect to action by written consent), and a majority
of the members of such a committee will constitute a quorum.    As used in the
Plan, "Committee" will refer to the Board or to such a committee, if
established.  To the extent consistent with corporate law, the Committee may
delegate to any officers of the Company the duties, power and authority of the
Committee under the Plan pursuant to such conditions or limitations as the
Committee may establish; provided, however, that only the Committee may exercise
such duties, power and authority with respect to Eligible Recipients who are
subject to Section 16 of the


                                          3
<PAGE>

Exchange Act.  The Committee may exercise its duties, power and authority under
the Plan in its sole and absolute discretion without the consent of any
Participant or other party, unless the Plan specifically provides otherwise.
Each determination, interpretation or other action made or taken by the
Committee pursuant to the provisions of the Plan will be conclusive and binding
for all purposes and on all persons, and no member of the Committee will be
liable for any action or determination made in good faith with respect to the
Plan or any Incentive Award granted under the Plan.

     3.2  AUTHORITY OF THE COMMITTEE.

          (a)  In accordance with and subject to the provisions of the Plan, the
     Committee will have the authority to determine all provisions of Incentive
     Awards as the Committee may deem necessary or desirable and as consistent
     with the terms of the Plan, including, without limitation, the following:
     (i) the Eligible Recipients to be selected as Participants; (ii) the nature
     and extent of the Incentive Awards to be made to each Participant
     (including the number of shares of Common Stock to be subject to each
     Incentive Award, any exercise price, the manner in which Incentive Awards
     will vest or become exercisable and whether Incentive Awards will be
     granted in tandem with other Incentive Awards) and the form of written
     agreement, if any, evidencing such Incentive Award; (iii) the time or times
     when Incentive Awards will be granted; (iv) the duration of each Incentive
     Award; and (v) the restrictions and other conditions to which the payment
     or vesting of Incentive Awards may be subject.  In addition, the Committee
     will have the authority under the Plan in its sole discretion to pay the
     economic value of any Incentive Award in the form of cash, Common Stock or
     any combination of both.

          (b)  The Committee will have the authority under the Plan to amend or
     modify the terms of any outstanding Incentive Award in any manner,
     including, without limitation, the authority to modify the number of shares
     or other terms and conditions of an Incentive Award, extend the term of an
     Incentive Award, accelerate the exercisability or vesting or otherwise
     terminate any restrictions relating to an Incentive Award, accept the
     surrender of any outstanding Incentive Award or, to the extent not
     previously exercised or vested, authorize the grant of new Incentive Awards
     in substitution for surrendered Incentive Awards; provided, however that
     the amended or modified terms are permitted by the Plan as then in effect,
     that no amendment or modification of an outstanding Incentive Award (other
     than as may be required pursuant to Section 4.3 of the Plan) may decrease
     the per share exercise price of an Option below the Fair Market Value of
     the Common Stock on the date of grant, and that any Participant adversely
     affected by such amended or modified terms has consented to such amendment
     or modification.

          (c)  In the event of (i) any reorganization, merger, consolidation,
     recapitalization, liquidation, reclassification, stock dividend, stock
     split, combination of shares, rights offering, extraordinary dividend or
     divestiture (including a spin-off) or any other change in corporate
     structure or shares, (ii) any purchase, acquisition, sale or disposition of
     a


                                          4
<PAGE>

     significant amount of assets or a significant business, (iii) any change in
     accounting principles or practices, or (iv) any other similar change, in
     each case with respect to the Company or any other entity whose performance
     is relevant to the grant or vesting of an Incentive Award, the Committee
     (or, if the Company is not the surviving corporation in any such
     transaction, the board of directors of the surviving corporation) may,
     without the consent of any affected Participant, amend or modify the
     vesting criteria of any outstanding Incentive Award that is based in whole
     or in part on the financial performance of the Company (or any Subsidiary
     or division or other subunit thereof) or such other entity so as equitably
     to reflect such event, with the desired result that the criteria for
     evaluating such financial performance of the Company or such other entity
     will be substantially the same (in the sole discretion of the Committee or
     the board of directors of the surviving corporation) following such event
     as prior to such event; provided, however, that the amended or modified
     terms are permitted by the Plan as then in effect.

4.   SHARES AVAILABLE FOR ISSUANCE.

     4.1  MAXIMUM NUMBER OF SHARES AVAILABLE.  Subject to adjustment as provided
in Section 4.3 of the Plan, the maximum number of shares of Common Stock that
will be available for issuance under the Plan will be 12,000,000 shares of
Common Stock.  Notwithstanding any other provisions of the Plan to the contrary,
no Participant in the Plan may be granted any Options or any other Incentive
Awards with a value based solely on an increase in the value of the Common Stock
after the date of grant, relating to more than 2,500,000 shares of Common Stock
in the aggregate during any 48- month period (subject to adjustment as provided
in Section 4.3 of the Plan).  The shares available for issuance under the Plan
may, at the election of the Committee, be either treasury shares or shares
authorized but unissued, and, if treasury shares are used, all references in the
Plan to the issuance of shares will, for corporate law purposes, be deemed to
mean the transfer of shares from treasury.

     4.2  ACCOUNTING FOR INCENTIVE AWARDS.  Shares of Common Stock that are
issued under the Plan or that are subject to outstanding Incentive Awards will
be applied to reduce the maximum number of shares of Common Stock remaining
available for issuance under the Plan.  Any shares of Common Stock that are
subject to an Incentive Award that lapses, expires, is forfeited or for any
reason is terminated unexercised or unvested and any shares of Common Stock that
are subject to an Incentive Award that is settled or paid in cash or any form
other than shares of Common Stock will automatically again become available for
issuance under the Plan.  Any shares of Common Stock that constitute the
forfeited portion of a Restricted Stock Award, however, will not become
available for further issuance under the Plan.

     4.3  ADJUSTMENTS TO SHARES AND INCENTIVE AWARDS.  In the event of any
reorganization, merger, consolidation, recapitalization, liquidation,
reclassification, stock dividend, stock split, combination of shares, rights
offering, divestiture or extraordinary dividend (including a spin-off) or any
other change in the corporate structure or shares of the Company, the Committee
(or, if the Company is not the surviving corporation in any such transaction,
the board of directors of the


                                          5
<PAGE>

surviving corporation) will make appropriate adjustment (which determination
will be conclusive) as to the number and kind of securities or other property
(including cash) available for issuance or payment under the Plan and, in order
to prevent dilution or enlargement of the rights of Participants, (a) the number
and kind of securities or other property (including cash) subject to outstanding
Incentive Awards, and (b) the exercise price of outstanding Options.

5.   PARTICIPATION.

     Participants in the Plan will be those Eligible Recipients who, in the
judgment of the Committee, have contributed, are contributing or are expected to
contribute to the achievement of economic objectives of the Company or its
Subsidiaries.  Eligible Recipients may be granted from time to time one or more
Incentive Awards, singly or in combination or in tandem with other Incentive
Awards, as may be determined by the Committee in its sole discretion.  Incentive
Awards will be deemed to be granted as of the date specified in the grant
resolution of the Committee, which date will be the date of any related
agreement with the Participant.

6.   OPTIONS.

     6.1  GRANT.  An Eligible Recipient may be granted one or more Options under
the Plan, and such Options will be subject to such terms and conditions,
consistent with the other provisions of the Plan, as may be determined by the
Committee in its sole discretion.  The Committee may designate whether an Option
is to be considered an Incentive Stock Option or a Non-Statutory Stock Option.
To the extent that any Incentive Stock Option granted under the Plan ceases for
any reason to qualify as an "incentive stock option" for purposes of Section 422
of the Code, such Incentive Stock Option will continue to be outstanding for
purposes of the Plan but will thereafter be deemed to be a Non-Statutory Stock
Option.

     6.2  EXERCISE PRICE.  The per share price to be paid by a Participant upon
exercise of an Option will be determined by the Committee in its discretion at
the time of the Option grant, provided that such price will not be less than
100% of the Fair Market Value of one share of Common Stock on the date of grant.

     6.3  EXERCISABILITY AND DURATION.  An Option will become exercisable at
such times and in such installments and upon such terms and conditions as may be
determined by the Committee in its sole discretion at the time of grant
(including without limitation that (i) the Participant remain in the continuous
employ or service of the Company or a Subsidiary for a certain period, (ii) the
Participant comply with certain requirements, (iii) the Participant, the Company
or any division or subunit thereof, satisfy certain performance goals or
criteria or (iv) the Common Stock satisfy certain performance goals or
criteria); provided, however, that no Option may be exercisable prior to six
months (other than as provided in Section 9.1 of the Plan) or after 10 years
from its date of grant.

     6.4  PAYMENT OF EXERCISE PRICE.  The total purchase price of the shares to
be purchased upon exercise of an Option will be paid entirely in cash (including
check, bank draft or money order);


                                          6
<PAGE>

provided, however, that the Committee, in its sole discretion and upon terms and
conditions established by the Committee, may allow such payments to be made, in
whole or in part, by tender of a Broker Exercise Notice, by tender (through
actual delivery or attestation) of Previously Acquired Shares or by a
combination of such methods.

     6.5  MANNER OF EXERCISE.  An Option may be exercised by a Participant in
whole or in part from time to time, subject to the conditions contained in the
Plan and in the agreement evidencing such Option, by delivery in person, by
facsimile or electronic transmission or through the mail of written notice of
exercise to the Company at its principal executive office in St. Paul, Minnesota
and by paying in full the total exercise price for the shares of Common Stock to
be purchased in accordance with Section 6.4 of the Plan.

7.   RESTRICTED STOCK AWARDS.

     7.1  GRANT.  An Eligible Recipient may be granted one or more Restricted
Stock Awards under the Plan, and such Restricted Stock Awards will be subject to
such terms and conditions, consistent with the other provisions of the Plan, as
may be determined by the Committee in its sole discretion.  The Committee may
impose such restrictions or conditions, not inconsistent with the provisions of
the Plan, to the vesting of such Restricted Stock Awards as it deems
appropriate, including, without limitation, that (i) the Participant remain in
the continuous employ or service of the Company or a Subsidiary for a certain
period; (ii) the Participant comply with certain requirements; (iii) the
Participant or the Company (or any Subsidiary or division or other subunit
thereof) satisfy certain performance goals or criteria; or (iv) the Common Stock
satisfy certain performance goals or criteria, provided, however, that other
than as provided in Section 9.1 of the Plan, no Restricted Stock Award may vest
prior to six months from its date of grant.

     7.2  RIGHTS AS A STOCKHOLDER; TRANSFERABILITY.  Except as provided in
Sections 7.1, 7.3, 7.4 and 12.3 of the Plan, a Participant will have all voting,
dividend, liquidation and other rights with respect to shares of Common Stock
issued to the Participant as a Restricted Stock Award under this Section 7 upon
the Participant becoming the holder of record of such shares as if such
Participant were a holder of record of shares of unrestricted Common Stock.

     7.3  DIVIDENDS AND DISTRIBUTIONS.  Unless the Committee determines
otherwise in its sole discretion (either in the agreement evidencing the
Restricted Stock Award at the time of grant or at any time after the grant of
the Restricted Stock Award), any dividends or distributions (other than regular
quarterly cash dividends) paid with respect to shares of Common Stock subject to
the unvested portion of a Restricted Stock Award will be subject to the same
restrictions as the shares to which such dividends or distributions relate.  The
Committee will determine in its sole discretion whether any interest will be
paid on such dividends or distributions.  The Committee, in an agreement
evidencing a Restricted Stock Award, may require that, unless the Participant
elects otherwise, regular quarterly cash dividends paid with respect to shares
of Common Stock subject to a portion of the Restricted Stock Award that has not
vested will be reinvested (and in such case


                                          7
<PAGE>

Participants hereby consent to such reinvestment) in shares of Common Stock
pursuant and in accordance with the Company's regular dividend reinvestment
plan.

     7.4  ENFORCEMENT OF RESTRICTIONS.  To enforce the restrictions referred to
in this Section 7, the Committee may place a legend on the stock certificates
referring to such restrictions and may require the Participant, until the
restrictions have lapsed, to keep the stock certificates, together with duly
endorsed stock powers, in the custody of the Company or its transfer agent, or
to maintain evidence of stock ownership, together with duly endorsed stock
powers, in a certificateless book-entry stock account with the Company's
transfer agent.

8.   PERFORMANCE STOCK AWARDS.

     An Eligible Recipient may be granted one or more Performance Stock Awards
under the Plan, and such Performance Stock Awards will be subject to such terms
and conditions, if any, consistent with the other provisions of the Plan, as may
be determined by the Committee in its sole discretion.  The Participant will
have all voting, dividend, liquidation and other rights with respect to the
shares of Common Stock issued to a Participant as a Performance Stock Award
under this Section 8 upon the Participant becoming the holder of record of such
shares; provided, however, that the Committee may impose such restrictions on
the assignment or transfer of a Performance Stock Award as it deems appropriate,
and may enforce such restrictions by any or all of the methods set forth in
Section 7.4 of the Plan.

9.   EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.

     9.1  TERMINATION OF EMPLOYMENT DUE TO DEATH OR DISABILITY.  In the event a
Participant's employment with the Company and all Subsidiaries is terminated by
reason of death or Disability:

          (a)  All outstanding Options then held by the Participant will become
     immediately exercisable in full and will remain exercisable for a period of
     five years after such termination (but in no event after the expiration
     date of any such Option);

          (b)  All Restricted Stock Awards then held by the Participant will
     become fully vested; and

          (c)  Any assignment or transfer restrictions with respect to
     Performance Stock Awards will lapse.

     9.2  TERMINATION OF EMPLOYMENT DUE TO RETIREMENT.  Subject to Section 9.6
of the Plan, in the event a Participant's employment with the Company and all
Subsidiaries is terminated by reason of Retirement:

          (a)  All outstanding Options then held by the Participant will, to the
     extent exercisable as of such termination, remain exercisable in full for a
     period of five years after


                                          8
<PAGE>

     such termination (but in no event after the expiration date of any such
     Option).  Options not exercisable as of such Retirement will be forfeited
     and terminate.

          (b)  All Restricted Stock Awards then held by the Participant that
     have not vested as of such termination will be terminated and forfeited;
     and

          (c)  Any assignment or transfer restrictions with respect to
     Performance Stock Awards that have not lapsed will continue in effect in
     accordance with their terms unless otherwise provided in the agreement
     evidencing such Performance Stock Awards.

     9.3  TERMINATION OF EMPLOYMENT FOR REASONS OTHER THAN DEATH, DISABILITY OR
RETIREMENT. Subject to Section 9.6 of the Plan, in the event a Participant's
employment is terminated with the Company and all Subsidiaries for any reason
other than death, Disability or Retirement, or a Participant is in the employ of
a Subsidiary and the Subsidiary ceases to be a Subsidiary of the Company (unless
the Participant continues in the employ of the Company or another Subsidiary):

          (a)  All outstanding Options then held by the Participant will, to the
     extent exercisable as of such termination, remain exercisable in full for a
     period of three months after such termination (but in no event after the
     expiration date of any such option).  Options not exercisable as of such
     termination will be forfeited and terminate.

          (b)  All Restricted Stock Awards then held by the Participant that
     have not vested as of such termination will be terminated and forfeited;
     and

          (c)  Any assignment or transfer restrictions with respect to
     Performance Stock Awards that have not lapsed will continue in effect in
     accordance with their terms unless otherwise provided in the agreement
     evidencing such Performance Stock Awards.

     9.4  TERMINATION OF SERVICE AS A NON-EMPLOYEE CONSULTANT OR ADVISOR.  In
the event a Participant's service as a non-employee consultant or advisor is
terminated with the Company and all Subsidiaries for any reason, or a
Participant is in the service of a Subsidiary and the Subsidiary ceases to be a
Subsidiary of the Company (unless the Participant continues in the service of
the Company or another Subsidiary), all rights of the Participant under the Plan
and any agreements evidencing an Incentive Award will immediately terminate
without notice of any kind, and (i) no Options then held by the Participant will
thereafter be exercisable, (ii) all Restricted Stock Awards then held by the
Participant that have not vested will be terminated and forfeited, and (iii) any
assignment or transfer restrictions with respect to Performance Stock Awards
that have not lapsed will continue in effect in accordance with their terms
unless otherwise provided in the agreement evidencing such Performance Stock
Awards; provided, however, that if such termination is due to any reason other
than termination by the Company or any Subsidiary for Cause (as defined in
Section 2.3 of the Plan), all outstanding Options then held by such Participant
will remain exercisable to the extent exercisable as of such termination for a
period of three months after such termination (but in no event after the
expiration date of any such Option).


                                          9
<PAGE>

     9.5  MODIFICATION OF RIGHTS UPON TERMINATION.  Notwithstanding the other
provisions of this Section 9, upon a Participant's termination of employment or
other service with the Company and all Subsidiaries, the Committee may, in its
sole discretion (which may be exercised at any time on or after the date of
grant, including following such termination), cause Options (or any part
thereof) then held by such Participant to become or continue to become
exercisable and/or remain exercisable following such termination of employment
or other service, and Restricted Stock Awards and Performance Stock Awards then
held by such Participant to vest and/or continue to vest or become free of
transfer restrictions, as the case may be, following such termination of
employment or other service, in each case in the manner determined by the
Committee; provided, however, that (a) no Incentive Award will become
exercisable or vest prior to six months from its date of grant (unless such
exercisability or vesting is by reason of death or Disability), and (b) no
Incentive Award may remain exercisable or continue to vest for more than two
years beyond the date such Incentive Award would have terminated if not for the
provisions of this Section 9.5 but in no event beyond its expiration date.

     9.6  EFFECTS OF ACTIONS CONSTITUTING CAUSE.  Notwithstanding anything in
the Plan to the contrary, in the event that a Participant is determined by the
Committee, acting in its sole discretion, to have committed any action which
would constitute Cause as defined in Section 2.3, irrespective of whether such
action or the Committee's determination occurs before or after termination of
such Participant's employment or other service with the Company or any
Subsidiary, all rights of the Participant under the Plan and any agreements
evidencing an Incentive Award then held by the Participant shall terminate and
be forfeited without notice of any kind.

     9.7  DETERMINATION OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.

          (a)  The change in a Participant's status from that of an employee of
     the Company or any Subsidiary to that of a non-employee consultant or
     advisor of the Company or any Subsidiary will, for purposes of the Plan, be
     deemed to result in a termination of such Participant's employment with the
     Company and its Subsidiaries, unless the Committee otherwise determines in
     its sole discretion.

          (b)  The change in a Participant's status from that of a non-employee
     consultant or  advisor of the Company or any Subsidiary to that of an
     employee of the Company or any Subsidiary will not, for purposes of the
     Plan, be deemed to result in a termination of such Participant's service as
     a non-employee consultant or advisor with the Company and its Subsidiaries,
     and such Participant will thereafter be deemed to be an employee of the
     Company or its Subsidiaries until such Participant's employment is
     terminated, in which event such Participant will be governed by the
     provisions of this Plan relating to termination of employment.

          (c)  Unless the Committee otherwise determines in its sole discretion,
     a Participant's employment or other service will, for purposes of the Plan,
     be deemed to have terminated on the date recorded on the personnel or other
     records of the Company or the Subsidiary for which the Participant provides
     employment, as determined by the Committee in its sole discretion based
     upon such records.

10.  PAYMENT OF WITHHOLDING TAXES.

     10.1  GENERAL RULES.  The Company is entitled to (a) withhold and deduct
from future wages of the Participant (or from other amounts that may be due and
owing to the Participant from the Company or a Subsidiary), or make other
arrangements for the collection of, all legally required amounts necessary to
satisfy any and all federal, state and local withholding and employment-related
tax requirements attributable to an Incentive Award, including, without
limitation, the grant, exercise or vesting of, or payment of dividends with
respect to, an Incentive Award or a disqualifying disposition of stock received
upon exercise of an Incentive Stock Option, or (b) require the Participant
promptly to remit the amount of such withholding to the Company before taking
any action, including issuing any shares of Common Stock, with respect to an
Incentive Award.

     10.2  SPECIAL RULES.  The Committee may, in its sole discretion and upon
terms and conditions established by the Committee, permit or require a
Participant to satisfy, in whole or in part, any withholding or
employment-related tax obligation described in Section 10.1 of the Plan by
electing to tender Previously Acquired Shares, a Broker Exercise Notice or a
combination of such methods.

11.  CHANGE IN CONTROL.

     11.1  CHANGE IN CONTROL.  For purposes of this Section 11, a "Change in
Control" of the Company will mean the following:

          (a)  Any "person" as such term is used in Sections 13(d) and 14(d) of
     the Exchange Act (other than the Company, any trustee or other fiduciary
     holding securities under any employee benefit plan of the Company, or any
     corporation owned, directly or indirectly, by the stockholders of the
     Company in substantially the same proportions as their ownership of stock
     of the Company), is or becomes, including pursuant to a tender or exchange
     offer for shares of Common Stock pursuant to which purchases are made, the
     "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act),
     directly or indirectly, of securities of the Company representing 25% or
     more of the combined voting power of the Company's then outstanding
     securities, other than in a transaction arranged or approved by the Board
     prior to its occurrence; provided, however, that if any such person will
     become the beneficial owner, directly or indirectly, of securities of the
     Company representing 34% or more of the combined voting power of the
     Company's then outstanding securities, a Change in Control will be deemed
     to occur whether or not any or all of such beneficial ownership is


                                          11
<PAGE>

     obtained in a transaction arranged or approved by the Board prior to its
     occurrence, and other than in a transaction in which such person will have
     executed a written agreement with the Company (and approved by the Board)
     on or prior to the date on which such person becomes the beneficial owner
     of 25% or more of the combined voting power of the Company's then
     outstanding securities, which agreement imposes one or more limitations on
     the amount of such person's beneficial ownership of shares of Common Stock,
     if, and so long as, such agreement (or any amendment thereto approved by
     the Board provided that no such amendment will cure any prior breach of
     such agreement or any amendment thereto) continues to be binding on such
     person and such person is in compliance (as determined by the Board in its
     sole discretion) with the terms of such agreement (including such
     amendment); provided, however, that if any such person will become the
     beneficial owner, directly or indirectly, of securities of the Company
     representing 50% or more of the combined voting power of the Company's then
     outstanding securities, a Change in Control will be deemed to occur whether
     or not such beneficial ownership was held in compliance with such a binding
     agreement.

          (b)  During any period of two consecutive years, individuals who at
     the beginning of such period constitute the Board, and any new director
     (other than a director designated by a person who has entered into an
     agreement with the Company to effect a transaction which would constitute a
     Change in Control pursuant to this Section 11.1) whose election by the
     Board or nomination for election by the Company's stockholders was approved
     by a  vote of at least two-thirds of the directors then still in office who
     either were directors at the beginning of the period or whose election or
     nomination for election was previously so approved, cease for any reason to
     constitute at least a majority thereof.

          (c)  The stockholders of the Company approve a merger or consolidation
     of the Company with any other corporation, other than (i) a merger or
     consolidation which would result in the voting securities of the Company
     outstanding immediately prior thereto continuing to represent (either by
     remaining outstanding or by being converted into voting securities of the
     surviving entity) more than 80% of the combined voting power of the voting
     securities of the Company or such surviving entity outstanding immediately
     after such merger or consolidation, or (ii) a merger or consolidation
     effected to implement a recapitalization of the Company (or similar
     transaction) in which no person acquires a percentage of the combined
     voting power of the Company's then outstanding securities which would
     constitute a Change in Control pursuant to Section 11.1 above.  In case of
     any consolidation or merger of another corporation into the Company in
     which the Company is the surviving corporation and in which there is a
     reclassification or change (including a change to the right to receive cash
     or other property) of the shares of Common Stock (other than a change in
     par value, or from par value to no par value, or as a result of a
     subdivision or combination, but including any change in such shares into
     two or more classes or series of shares), Section 4.3 of the Plan will
     apply.


                                          12
<PAGE>

          (d)  The stockholders of the Company approve a plan of complete
     liquidation of the Company or an agreement for the sale or disposition by
     the Company of all or substantially all of the Company's assets.

     11.2  ACCELERATION OF VESTING.  Without limiting the authority of the
Committee under Sections 3.2 and 4.3 of the Plan, if a Change in Control of the
Company occurs, then, if approved by the Committee in its sole discretion either
in an agreement evidencing an Incentive Award at the time of grant or at any
time after the grant of an Incentive Award, (a) all Options that have been
outstanding for at least six months will become immediately exercisable in full
and will remain exercisable in accordance with their terms; (b) all outstanding
Restricted Stock Awards that have been outstanding for at least six months will
become immediately fully vested and non-forfeitable; and (c) any transfer
restrictions with respect to Performance Stock Awards will lapse.

     11.3  CASH PAYMENT FOR OPTIONS.  If a Change in Control of the Company
occurs, then the Committee, if approved by the Committee in its sole discretion
either in an agreement evidencing an Incentive Award at the time of grant or at
any time after the grant of an Incentive Award, and without the consent of any
Participant affected thereby, may determine that some or all Participants
holding outstanding Options will receive, with respect to some or all of the
shares of Common Stock subject to such Options, as of the effective date of any
such Change in Control of the Company, cash in an amount equal to the excess of
the Fair Market Value of such shares immediately prior to the effective date of
such Change in Control of the Company over the exercise price per share of such
Options.

     11.4  LIMITATION ON CHANGE IN CONTROL PAYMENTS.  Notwithstanding anything
in Section 11.2 or 11.3 of the Plan to the contrary, if, with respect to a
Participant, any of the payments to be made in connection with Section 11.2 or
11.3 of the Plan, together with any other payments or benefits which a
Participant has the right to receive from the Company or any corporation which
is a member of an "affiliated group" (as defined in section 1504(a) of the Code
without regard to section 1504(b) of the Code) of which the Company is a member,
constitute an "excess parachute payment" (as defined in section 280G(b) of the
Code), the payments to be made in connection with Section 11.2 or 11.3 of the
Plan shall be reduced to the extent necessary to prevent any portion of such
payments or benefits from becoming subject to the excise tax imposed under
section 4999 of the Code;  provided, however, that if a Participant is subject
to a separate agreement with the Company or a Subsidiary that expressly
addresses the potential application of Sections 280G or 4999 of the Code
(including, without limitation, that "payments" under such agreement or
otherwise will be reduced, that such payments will not be reduced or that the
Participant will have the discretion to determine which "payments" will be
reduced), then this Section 11.4 will not apply, and any "payments" to a
Participant pursuant to Section 11.2 or 11.3 of the Plan will be treated as
"payments" arising under such separate agreement.


                                          13

12.  RIGHTS OF ELIGIBLE RECIPIENTS AND PARTICIPANTS; TRANSFERABILITY.

     12.1  EMPLOYMENT OR OTHER SERVICE.  Nothing in the Plan will interfere with
or limit in any way the right of the Company or any Subsidiary to terminate the
employment or Other Service of any Eligible Recipient or Participant at any
time, nor confer upon any Eligible Recipient or Participant any right to
continue in the employ or Other Service of the Company or any Subsidiary.

     12.2  RIGHTS AS A STOCKHOLDER.  As a holder of Incentive Awards (other than
Restricted Stock Awards and Performance Stock Awards), a Participant will have
no rights as a stockholder unless and until such Incentive Awards are exercised
for, or paid in the form of, shares of Common Stock and the Participant becomes
the holder of record of such shares.  Except as otherwise provided in the Plan,
no adjustment will be made for dividends or distributions with respect to such
Incentive Awards as to which there is a record date preceding the date the
Participant becomes the holder of record of such shares, except as the Committee
may determine in its discretion.

     12.3  RESTRICTIONS ON TRANSFER.  Except pursuant to testamentary will or
the laws of descent and distribution or as otherwise expressly permitted by the
Plan, no right or interest of any Participant in an Incentive Award prior to the
exercise or vesting of such Incentive Award will be assignable or transferable,
or subjected to any lien, during the lifetime of the Participant, either
voluntarily or involuntarily, directly or indirectly, by operation of law or
otherwise.  A Participant will, however, be entitled to designate a beneficiary
to receive an Incentive Award upon such Participant's death, and in the event of
a Participant's death, payment of any amounts due under the Plan will be made
to, and exercise of any Options (to the extent permitted pursuant to Section 9
of the Plan) may be made by, the Participant's legal representatives, heirs and
legatees.

     12.4  NON-EXCLUSIVITY OF THE PLAN.  Nothing contained in the Plan is
intended to modify or rescind any previously approved compensation plans or
programs of the Company or create any limitations on the power or authority of
the Board to adopt such additional or other compensation arrangements as the
Board may deem necessary or desirable.

13.  SECURITIES LAW AND OTHER RESTRICTIONS.

     Notwithstanding any other provision of the Plan or any agreements entered
into pursuant to the Plan, the Company will not be required to issue any shares
of Common Stock under this Plan, and a Participant may not sell, assign,
transfer or otherwise dispose of shares of Common Stock issued pursuant to
Incentive Awards granted under the Plan, unless (a) there is in effect with
respect to such shares a registration statement under the Securities Act and any
applicable securities laws of a state or foreign jurisdiction or an exemption
from such registration under the Securities Act and applicable state or foreign
securities laws, and (b) there has been obtained any other consent, approval or
permit from any other regulatory body which the Committee, in its sole
discretion, deems necessary or advisable.  The Company may condition such
issuance, sale or transfer upon the receipt of any representations or agreements
from the parties involved, and the placement of any


                                          14
<PAGE>

legends on certificates representing shares of Common Stock, as may be deemed
necessary or advisable by the Company in order to comply with such securities
law or other restrictions.

14.  PLAN AMENDMENT, MODIFICATION AND TERMINATION.

     The Board may suspend or terminate the Plan or any portion thereof at any
time, and may amend the Plan from time to time in such respects as the Board may
deem advisable in order that Incentive Awards under the Plan will conform to any
change in applicable laws or regulations or in any other respect the Board may
deem to be in the best interests of the Company; provided, however, that no
amendments to the Plan will be effective without approval of the stockholders of
the Company if stockholder approval of the amendment is then required pursuant
to Section 422 of the Code or the rules of the New York Stock Exchange.  No
termination, suspension or amendment of the Plan may adversely affect any
outstanding Incentive Award without the consent of the affected Participant;
provided, however, that this sentence will not impair the right of the Committee
to take whatever action it deems appropriate under Sections 3.2, 4.3 and 11 of
the Plan.

15.  EFFECTIVE DATE AND DURATION OF THE PLAN.

     The Plan is effective, as amended and restated, as of May 14, 1999 or such
later date as the Plan is approved by the Company's stockholders and shall apply
to Incentive Awards granted on or after such effective date.  The Plan will
terminate at midnight on June 30, 2005, and may be terminated prior to such time
to by Board action, and no Incentive Award will be granted after such
termination.  Incentive Awards outstanding upon termination of the Plan may
continue to be exercised, or become free of restrictions, in accordance with
their terms.

16.  MISCELLANEOUS.

     16.1  GOVERNING LAW.  The validity, construction, interpretation,
administration and effect of the Plan and any rules, regulations and actions
relating to the Plan will be governed by and construed exclusively in accordance
with the laws of the State of Minnesota, notwithstanding the conflicts of laws
principles of any jurisdictions.

     16.2  SUCCESSORS AND ASSIGNS.  The Plan will be binding upon and inure to
the benefit of the successors and permitted assigns of the Company and the
Participants.

million.  If the Committee determines in good faith that there is a reasonable
likelihood that any compensation paid or payable to a Participant by the Company
or a Subsidiary pursuant to the Plan for a Plan Year would not be deductible by
the Company or the Subsidiary solely by reason of the limitation under Section
162(m) of the Code, the Committee may defer all or a portion of the amounts
otherwise payable pursuant to the Plan to the extent deemed necessary by the
Committee to ensure that the entire amount of any distribution to such
Participant is deductible.  If so determined by the Committee, such deferred
amounts, when paid to the Participant, may be accompanied by interest at a
reasonable rate (as determined by the Committee).

7.   EFFECT OF TERMINATION OF EMPLOYMENT.

     7.1  TERMINATION DUE TO DEATH, DISABILITY OR RETIREMENT.  In the event a
Participant's employment with the Company and all Subsidiaries is terminated by
reason of death, Disability or Retirement during a Performance Period, the
Participant (or the Participant's estate) (subject to the Committee's discretion
as allowed by clause (y) of Section 3.1 of the Plan) shall be paid (pursuant to
Section 6 of the Plan after the completion of the Plan Year) a percentage of the
amount earned according to the terms of the Award equal to the portion of the
Performance Period through the Participant's death, Disability or Retirement, as
the case may be, as determined by the Committee.

     7.2  TERMINATION FOR REASONS OTHER THAN DEATH, DISABILITY OR RETIREMENT.
In the event a Participant's employment is terminated with the Company and all
Subsidiaries prior to the end of the Performance Period for any reason other
than death, Disability or Retirement, or a Participant is in the employ of a
Subsidiary and the Subsidiary ceases to be a Subsidiary of the Company (unless
the Participant continues in the employ of the Company or another Subsidiary),
the Participant's Award for such Performance Period shall be immediately
forfeited and the Participant shall have no right to any payment thereafter;
provided, however, that under such circumstances the Committee may pay the
Participant an amount not to exceed a percentage of the amount earned according
to the terms of the Award equal to the portion of the Performance Period through
the Participant's termination.

8.   PAYMENT OF WITHHOLDING TAXES.

     The Company is entitled to withhold and deduct from the payment made
pursuant to an Award or from future wages of the Participant (or from other
amounts that may be due and owing to the Participant from the Company or a
Subsidiary), or make other arrangements for the collection of, all legally
required amounts necessary to satisfy any and all federal, state and local
withholding and employment-related tax requirements attributable to any payment
made pursuant to an Award.

9.   RIGHTS OF ELIGIBLE EXECUTIVE OFFICERS AND PARTICIPANTS; TRANSFERABILITY.

     9.1  EMPLOYMENT.  Nothing in the Plan will interfere with or limit in any
way the right of the Company or any Subsidiary to terminate the employment or
otherwise modify the


                                          6
<PAGE>

terms and conditions of the employment of any Executive Officer or Participant
at any time, nor confer upon any Executive Officer or Participant any right to
continue in the employ of the Company or any Subsidiary.

     9.2  RESTRICTIONS ON TRANSFER.  Except pursuant to testamentary will or the
laws of descent and as otherwise expressly permitted by the Plan, no right or
interest of any Participant in an Award will be assignable or transferable, or
subjected to any lien, during the lifetime of the Participant, either
voluntarily or involuntarily, directly or indirectly, by operation of law or
otherwise.

     9.3  NON-EXCLUSIVITY OF THE PLAN.  Nothing contained in the Plan is
intended to modify or rescind any previously approved compensation plans or
programs of the Company or any Subsidiary or create any limitations on the power
or authority of the Board or any committee thereof to adopt such additional or
other compensation arrangements as the Board or committee may deem necessary or
appropriate.

10.  PLAN AMENDMENT, MODIFICATION AND TERMINATION.

     The Board may suspend or terminate the Plan or any portion thereof at any
time, and may amend the Plan from time to time in such respects as the Board may
deem advisable in order that Awards under the Plan will conform to any change in
applicable laws or regulations or in any other respect the Board may deem to be
in the best interests of the Company; provided, however, that no amendments to
the Plan will be effective without the approval of the stockholders of the
Company if stockholder approval of the amendment is then required for the Plan
to continue to be a qualified performance-based compensation plan pursuant to
Section 162(m) of the Code.  Any termination, suspension or amendment of the
Plan may adversely affect any outstanding Award without the consent of the
affected Participant.

11.  UNFUNDED, UNSECURED OBLIGATION.

     A Participant's only interest under the Plan shall be the right to receive
a cash payment under an Award pursuant to the terms of the Award and the Plan
(subject to the authority of the Committee pursuant to Sections 3 and 10 of the
Plan).  No portion of the amount payable to Participants upon the achievement of
any Performance Goal therein shall be held by the Company or any Subsidiary in
trust or escrow or any other form of asset segregation.  To the extent that a
participant acquires a right to receive such a cash payment under the Plan, such
right shall be no greater than the right of any unsecured, general creditor of
the Company.

12.  EFFECTIVE DATE AND DURATION OF THE PLAN.

     The Plan, as amended and restated, was approved by the Board on February
19, 1999, subject to the approval of the stockholders of the Company as required
by Section 162(m) of the Code.  No benefits will be granted or amounts will be
paid pursuant to the Plan unless and until such approval of the Plan by the
stockholders of the Company.  The Plan shall be effective for


                                          7
<PAGE>

the Plan Year beginning on January 1, 1999 and will remain in effect through and
including the Plan Year ending December 31, 2003.  The Plan may be terminated at
any time by the Board.  Any payments pursuant to Awards outstanding upon
termination of the Plan may continue to be made in accordance with the terms of
the Awards, subject to the authority of the Committee pursuant to Sections 3 and
10 of the Plan.

13.  MISCELLANEOUS.

     13.1 GOVERNING LAW.  The validity, construction, interpretation,
administration and effect of the Plan and any rules, regulations and actions
relating to the Plan will be governed by and construed exclusively in accordance
with the internal, substantive laws of the State of Minnesota, without regard to
the conflict of law rules of the State of Minnesota or any other jurisdiction.

     13.2 SUCCESSORS.  The Plan will be binding upon and inure to the benefit of
the successors of the Company and the Participants.
