           NOTICE OF SPECIAL MEETING OF GCS SERVICE, INC. STOCKHOLDERS
                                JULY 10, 1998
    


TO THE STOCKHOLDERS OF GCS SERVICE, INC.:
   
       NOTICE IS HEREBY GIVEN of a special meeting of stockholders (including 
any adjournment or postponement thereof, the "Special Meeting") of GCS 
Service, Inc., a Delaware corporation ("GCS" or, the "Company") to be held at 
the offices of Edwards & Angell at 101 Federal Street, Boston, Massachusetts 
02110 on July 10, 1998, at 9:00 a.m., local time. The purpose of the Special 
Meeting is to consider and vote upon the following matters:
    
(1)    A proposal to adopt an Agreement and Plan of Merger, dated as of May 12,
       1998 (the "Merger Agreement") (as such agreement may be amended, 
       supplemented or otherwise modified from time to time) among Ecolab Inc.,
       GCS Acquisition Corporation, GCS and Wesley B. Tyler and the transactions
       contemplated thereby, including the appointment by GCS of Wesley B. Tyler
       as the Stockholder Representative (as defined in the Merger Agreement).
       GCS Acquisition Corporation ("Merger Sub") is a wholly-owned subsidiary
       of Ecolab that was formed solely to implement the merger of Merger Sub
       into GCS (the "Merger"). If the Agreement and Plan of Merger is adopted
       by stockholders and the other conditions to the merger are satisfied or
       waived, each outstanding share of GCS common stock (other than shares
       held by stockholders of GCS who have properly exercised their dissenters'
       rights under Delaware law) will be cancelled and converted into the
       right to receive a number of shares of common stock of Ecolab,
       including associated preferred stock purchase rights (the "Ecolab
       Common Stock"), as described in the attached proxy statement/prospectus
       (the "Proxy Statement/Prospectus"); and

(2)    To transact such other business as may properly come before the Special 
       Meeting or any postponement or adjournment thereof.

       Any stockholder who does not wish to accept the merger consideration 
of Ecolab Common Stock (the "Merger Consideration") and who properly demands 
appraisal under Delaware law will have the right to have the fair value of 
his or her shares determined by the Delaware Chancery Court. This appraisal 
right is subject to a number of restrictions and technical requirements 
described in the attached proxy statement.

   
       The Board of Directors of GCS has fixed the close of business on June 
5, 1998, as the record date (the "Record Date") for determination of the 
stockholders entitled to receive notice of, and to vote at, the Special 
Meeting. The Special Meeting may be postponed or adjourned from time to time 
without any notice other than by announcement at the Special Meeting.

       The affirmative vote of the holders of a majority of the shares of GCS 
Common Stock outstanding on the Record Date is required to approve the above 
proposal. Stockholders may vote in person or by proxy. The proxy statement, 
which explains the merger in detail and the accompanying proxy card are 
attached to this notice. Holders of record of common stock at the close of 
business on June 5, 1998 will be entitled to vote at the meeting or any 
adjournment thereof with respect to all matters described above. PLEASE SIGN, 
DATE AND MAIL THE ENCLOSED PROXY (WHICH IS SOLICITED BY THE BOARD OF 
DIRECTORS) PROMPTLY USING THE ENCLOSED ENVELOPE.

June 11, 1998                          By Order of the Board of Directors
    

                                       Wesley B. Tyler
                                       President

                         SPECIAL MEETING OF STOCKHOLDERS
                              TO BE HELD ON JULY 10, 1998
    

                           QUESTIONS AND ANSWERS ABOUT
                                   THE MERGER

Q:       WHAT WILL I RECEIVE IN THE MERGER?

A:       As a GCS stockholder, you will receive a certain number of shares of
         Ecolab Common Stock in exchange for each of your GCS shares. The exact
         number of shares you will receive for each GCS share will be computed
         using a somewhat complicated formula that is explained in more detail
         in this Proxy Statement/Prospectus.

         In essence, the formula starts with Ecolab's estimate of a purchase
         price for GCS of approximately $26 million. Next, we will either add to
         or subtract from the $26 million any amount by which the net worth of
         GCS, as of the closing date of the Merger, is greater than or less than
         $5.8 million. We will then divide that number by the average closing
         price of Ecolab Common Stock on the New York Stock Exchange during the
         twenty day period ending four days prior to closing.

         That gives the total number of shares to be issued to GCS stockholders.
         By dividing that number by the total number of shares of GCS, we
         determine how many shares of Ecolab Common Stock you will receive for
         each share of GCS common stock (the "GCS Common Stock") you own.

         The number of shares you may receive is subject to further adjustment 
         after closing based upon any changes in the net worth of GCS in the 
         final closing-day balance sheet (to be prepared within 60 days after
         the closing) from the net worth in the estimated closing-day balance
         sheet. If the final net worth is greater or lesser than the 
         estimated net worth, you will receive additional shares of Ecolab
         or will be required to return shares of Ecolab already received.
   
         Of the shares of Ecolab Common Stock received by you in the Merger, 
         10% will be held in escrow for a period of at least two years after 
         the closing. These shares will be used to satisfy any downward 
         adjustment in the number of shares you receive as described in the 
         preceding paragraph.
    
         We will not issue fractional shares of Ecolab Com mon Stock. Instead,
         you will receive a whole share of Ecolab Common Stock for any
         fractional share you own.

Q:       CAN YOU GIVE ME AN EXAMPLE OF HOW YOU WILL
         CALCULATE THE NUMBER OF ECOLAB SHARES I WILL
         RECEIVE?

A:       The following is a hypothetical example of how the
         formula would be used to determine the number of
         shares that will be issued in the Merger.  If we as
         sume:

              -   The average share price of Ecolab Common Stock during the
                  relevant period is $31.00 (which was the approximate trading
                  price on May 27, 1998).

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THE ECOLAB COMMON STOCK TO BE ISSUED
IN THE MERGER OR DETERMINED IF THIS PROXY STATEMENT /PROSPECTUS IS TRUTHFUL OR
COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

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

                                       1
<PAGE>


              -   The number of shares of GCS Common
                  Stock outstanding on the closing date is
                  161,143.

              -   The estimated net worth of GCS is $6,000,000.

                      Again, we start with an estimated purchase price for GCS
              of $26,363,671.  Because in our example the estimated net worth
              of GCS is $200,000 higher than the $5,800,000 benchmark in
              the Merger Agreement, the estimated purchase price for use 
              in the formula is increased by $200,000 to $26,563,671. This 
              number is then divided by the average closing price of Ecolab 
              stock of $31.00. The resulting ratio would be 5.32 shares of 
              Ecolab for each share of GCS. The number of shares you may 
              receive is subject to further adjustment after closing based 
              upon any changes in the net worth of GCS in the final closing-day
              balance sheet (to be prepared within 60 days after the closing) 
              from the net worth in the estimated closing-day balance
              sheet. If the final net worth is greater or lesser than the 
              estimated net worth, you will receive additional shares of Ecolab
              or will be required to return (from escrow) shares of Ecolab 
              already received.


Q:       WHEN WILL YOU DETERMINE THE EXACT EXCHANGE
         RATIO?

A:       The exchange ratio shall be determined immediately
         following the twenty day period ending four days 
         prior to the closing of the Merger.

         After stockholder approval, GCS does not have a right to call off 
         the Merger if the Ecolab stock price goes up or down. GCS believes, 
         however, that the formula protects the value that Ecolab will pay, 
         because it values the stock based on a twenty day average of the 
         trading prices close to the time of the Merger. This means that, if 
         the average Ecolab stock price goes down, Ecolab will have to issue 
         more shares to pay the purchase price. If the average Ecolab stock 
         price goes up, Ecolab will issue fewer shares to pay the same 
         purchase price.

Q:       WHEN, AND UNDER WHAT CIRCUMSTANCES, DO I
         RECEIVE THE SHARES HELD IN ESCROW?
   
A:       10% of the aggregate merger consideration will be held in the escrow 
         for at least two years.  It will be held not only for purchase price 
         adjustments (as discussed above) but also for indemnification 
         claims.  If certain representations and warranties made by GCS in 
         the Merger Agreement are later shown to have been untrue when they 
         were made and, be cause of this, Ecolab or GCS suffers a loss, then 
         an amount of the Ecolab shares in the escrow equiva lent to the 
         amount of the loss will be returned to Ecolab as reimbursement.  
         There are certain restrictions on the timing and the amount of 
         Ecolab shares that would be returned including certain threshold 
         amounts of losses which must be incurred before the escrow is used.  
         For further details of the indemnification provisions, see page 17.
    
Q:       WHY IS THE BOARD OF GCS RECOMMENDING THAT I
         VOTE FOR THE MERGER AGREEMENT?

A:       In the opinion of your Board, relying in part upon
         a fairness opinion from an independent financial
         advisor, the Merger is in the best interests of GCS
         and the merger consideration is fair to the stock

Q:       WHEN DO YOU EXPECT THE MERGER TO BE COM
         PLETED?
   
A:       We are working towards completing the Merger as
         quickly as possible.  We expect to complete the
         Merger by early July 1998.
    
Q:       WHAT ARE THE TAX CONSEQUENCES OF THE MERGER?

A:       The Merger is intended to qualify as a reorganiza
         tion within the meaning of Section 368(a) of the tax
         code, so that, for Federal income tax purposes, the
         Merger will not result in gain or loss by Ecolab,
         GCS or, except to the extent you receive cash
         pursuant to the Merger, stockholders of GCS.  To
         review the tax consequences to stockholders in
         greater detail, see page 20.
                                  

Q:       WILL I HAVE APPRAISAL RIGHTS?

A:       GCS is organized under Delaware law.  Under
         Delaware law, you are entitled to seek appraisal and
         payment of the fair value of your GCS shares.  In
         order to do so, you must file a written objection to
         the Merger prior to the Special Meeting, not vote in
         favor of the Merger and meet other legal require
         ments.  The requirements for seeking appraisal are
         summarized in the Proxy Statement/Prospectus
         (page 18) and the Delaware law that governs
         appraisal rights is attached as Annex II.  If you wish
         to seek an appraisal of your shares, you should read
         and follow those provisions carefully.  You should
         be aware that an appraisal may result in a price for
         your shares that has more value or less value than
         the Ecolab shares being issued in the Merger.

Q:       WHAT OTHER MATTERS WILL BE VOTED ON AT THE
         SPECIAL MEETING?

A:       We do not expect to ask you to vote on any other
         matters at the Special Meeting.

                               THE SPECIAL MEETING

         VOTING
   
         At the Special Meeting, the holders of GCS Common Stock will vote on a
         proposal to adopt the Merger Agreement. Each share is entitled to one
         vote. Delaware law requires that a majority of all outstanding GCS
         shares vote to approve the Merger, and Wesley B. Tyler, President 
         of GCS, holds enough shares to assure that majority.

         The record date for determining who is entitled to vote at the Special
         Meeting has been set at June 5, 1998. On the record date, there were
         147,118 shares of GCS Common Stock outstanding and entitled to vote, 
         held by 36 stockholders of record.

                                 SPECIAL FACTORS

         PURPOSE, STRUCTURE AND EFFECTS OF THE MERGER
         (PAGE 11)

         Ecolab's purpose for the Merger is to further its growth strategies.
         Ecolab and GCS structured the transaction as a merger because a merger
         offers an advantageous tax structure. After the Merger, GCS will be a
         wholly-owned subsidiary of Ecolab.

         RECOMMENDATION OF THE GCS BOARD OF DIRECTORS
         (PAGE 13)

         GCS' Board of Directors has unanimously approved the Merger Agreement
         and recommends that you vote to adopt the Merger Agreement. The GCS
         Board of Directors believes that the Merger is in the best interests of
         GCS and its stockholders and that the Merger Consideration is fair to
         each stockholder from a financial point of view.

         FACTORS CONSIDERED BY THE GCS BOARD OF DIREC
         TORS (PAGE 13)

         In reaching its decision to recommend adoption of the Merger Agreement,
         the Board considered a number of factors. These include the following:

         -    the attractiveness of the Merger Consideration
              in terms of value, liquidity and growth;

         -    the structure of the Merger as a tax-free trans
              action; and

         -    opportunities for enhanced efficiencies and growth of GCS' core
              business and development of new products and markets for GCS.

         FAIRNESS OPINION (PAGE 13)
   
         Carter Capital Corporation subsequently delivered to the GCS Board a
         written opinion that the Merger Consideration was fair to the GCS 
         stockholders from a financial point of view.
    
         INTERESTS OF GCS MANAGEMENT IN THE MERGER
         (PAGE 17)

         Certain GCS Board members and officers own GCS Common Stock and, to
         that extent, their interest in the Merger is the same as yours. How
         ever, some of the officers and directors of GCS have relationships, or
         interests in the Merger, that are different from your interests as a
         stockholder or that could present a conflict of interest. Some of these
         interests are set forth below. The Board was aware of these interests
         and considered them in recommending and approving the Merger.

         Wesley B. Tyler is a party to the Merger Agreement and has agreed to
         indemnify Ecolab, its directors, officers and affiliates against
         certain losses, claims or liabilities arising in connection with the
         Merger, above and beyond any indemnification obligations of other GCS
         stockholders. Further, Ecolab and Mr. Tyler have entered into an
         employment, bonus and non-competition agreement effective upon
         consummation of the Merger.


                                   THE MERGER

         THE MERGER CONSIDERATION

         If the conditions to the Merger that are described below are satisfied
         or waived, GCS stockholders will receive a certain number of shares of
         Ecolab Common Stock in exchange for each share of GCS Common Stock they
         own. The exact number of shares will be determined after the closing,
         based upon a formula as adjusted for post-closing final balance sheet
         adjustments. The formula is based upon an estimated purchase price of
         approximately $26 million and will be adjusted after the closing of the
         Merger based upon a required net worth of GCS of $5.8 million and the
         average share price of Ecolab stock for 20 consecutive trading days
         ending on the fourth day prior to the Merger.

         CONDITIONS TO THE MERGER (PAGE 16)
   
         The obligations of both GCS and Ecolab to complete the Merger are
         subject to a number of conditions. The most important of these mutual
         conditions are:
    
         -    receipt of the approval of the majority of the
              GCS stockholders entitled to vote at the Spe
              cial Meeting of GCS stockholders;

         -    absence of legal restraints or prohibitions that
              prevent completion of the Merger; and

         -    obtaining all governmental authorizations needed to complete the
              Merger (as of the date of this Proxy Statement/Prospectus all such
              authorizations have been obtained).

         Several additional conditions exist to the obligation of Ecolab to
         complete the Merger. The most important of these conditions are:

         -    GCS' compliance with the Merger Agreement;
              and

         -    the truth of the representations and warranties
              made by GCS in the Merger Agreement.

         Additional conditions exist to the obligation of GCS to complete the
         Merger. The most important of these conditions are:

         -    Ecolab's compliance with the Merger Agree
              ment; and

         -    the truth of the representations and warranties
              made by Ecolab in the Merger Agreement.

         The mutual conditions cannot be waived. All other conditions can be
         waived by the party for whose benefit the condition operates.

         TERMINATION OF THE MERGER AGREEMENT
         (PAGE 17)

         Either GCS or Ecolab may terminate the Merger Agreement if:

         -    the Merger has not been completed by
              November 30, 1998;

         -    a law or final court order prohibits the Merger;
              or

         -    the other party fails to comply with the Merger
              Agreement.

         APPRAISAL RIGHTS (PAGE 18)
   
         Any stockholder who does not wish to accept the Merger Consideration
         has the right under Delaware law to have the "fair value" of his or her
         shares determined by the Delaware Chancery Court. This "right of
         appraisal" is subject to a number of restrictions and technical
         requirements. Generally, in order to exercise appraisal rights:
    
         -    you must not vote in favor of the Merger; and

         -    you must make a written demand for appraisal
              before the vote on the Merger.

         Merely voting against the Merger will not protect your right of
         appraisal. Annex II contains the Delaware appraisal statute.

         FEDERAL INCOME TAX CONSEQUENCES (PAGE 20)

         Generally, you will not be subject to federal income tax as a result of
         any gain you realize pursuant to the Merger, except to the extent that
         you receive cash in the Merger.

         ACCOUNTING TREATMENT (PAGE 15)

         The Merger is expected to be accounted for as a purchase in accordance
         with generally accepted accounting principles.

         FORWARD-LOOKING STATEMENTS MAY PROVE TO BE
         INACCURATE (PAGE 34)

         Ecolab and GCS have made forward-looking statements in this Proxy
         Statement/Prospectus that are subject to risks and uncertainties.
         Forward- looking statements include the information con cerning
         possible or assumed future results of opera tions of GCS and Ecolab, as
         well as statements preceded by, followed by or that include the words
         "believes," "expects," "anticipates," or similar terms. Certain
         important factors, in addition to those discussed in other places in
         this Proxy State ment/Prospectus and in the documents which are
         incorporated by reference, could affect future results of GCS and
         Ecolab and could cause those results to differ materially from those
         expressed in our forward-looking statements. Such factors include,
         among others, the following:

         -    operating, legal and regulatory risks;

         -    risks that anticipated cost savings from the
              combination of GCS and Ecolab will not be
              realized;

         -    risks that costs from the integration of GCS
              with Ecolab will be greater than expected; and

         -    economic, political and competitive forces
              affecting GCS' and Ecolab's businesses.

                  This Proxy Statement/Prospectus is being furnished to 
holders of GCS Common Stock in connection with the solicitation of proxies by 
the GCS Board of Directors for use at the Special Meeting to be held on

                  THE GCS BOARD OF DIRECTORS HAS DETERMINED THAT THE TERMS OF 
THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, GCS AND THE GCS 
STOCKHOLDERS, HAS APPROVED AND ADOPTED THE MERGER AGREEMENT AND THE 
TRANSACTIONS CONTEMPLATED THEREBY, AND RECOMMENDS THAT THE GCS STOCKHOLDERS

                  This Proxy Statement/Prospectus is also furnished by Ecolab 
to GCS stockholders as a prospectus in connection with the issuance by Ecolab

                  This Proxy Statement/Prospectus, the attached Notice of 
Special Meeting of GCS Service, Inc. stockholders, and the form of proxy 
enclosed herewith are first being mailed to stockholders of GCS on or about 
June 11, 1998.

DATE, PLACE AND TIME


                  The Special Meeting will be held at the principal offices 
of Edwards & Angell, 101 Federal Street, Boston, Massachusetts, on July 10, 
1998, at 9:00 a.m., local time.
    

MATTERS TO BE CONSIDERED AT THE MEETING

                  At the Special Meeting, holders of shares of GCS Common 
Stock as of the Record Date will be asked to consider and vote upon a 
proposal to approve and adopt the Merger Agreement and the transactions 
contemplated thereby including the appointment of Wesley B. Tyler as 
Stockholder Representative. See " THE MERGER." The description of the Merger 
and the Merger Agreement in this Proxy Statement/Prospectus is, of necessity, 
selective and is, therefore, qualified in its entirety by reference to the 
Merger Agreement. A copy of the full text of the Merger Agreement is attached 
to this Proxy Statement/Prospectus as Annex I hereto.

RECORD DATE; VOTE REQUIRED
   
                  The GCS Board of Directors has fixed June 5, 1998 as 
the Record Date for the determination of the GCS stockholders entitled to 
notice of and to vote at the Special Meeting. On the Record Date, 147,118
shares of GCS Common Stock were outstanding. Shares of GCS Common Stock are 
the only outstanding voting securities of GCS. Each holder of record of 
shares of GCS Common Stock on the Record Date is entitled to cast one vote 
per share. Each stockholder may vote in person or by properly executed proxy, 
upon each matter properly submitted for the vote of the GCS stockholders at 
the Special Meeting. The presence, in person or by proxy, of the holders of a 
majority of the shares of GCS Common Stock outstanding and entitled to vote 
at the Special Meeting is necessary to constitute a quorum at the Special 
Meeting.
    
                  Holders of shares of GCS Common Stock on the Record Date 
will be entitled to dissenters' rights under the Delaware General Corporation 
Law (the "DGCL") in connection with the Merger. GCS stockholders who vote in 
favor of the Merger, however, will waive their dissenters' rights. See "THE 
MERGER -- Dissenters' Rights" and Annex II -- Section 262 of the DGCL.
   
                  The affirmative vote of the holders of a majority of the 
outstanding shares of GCS Common Stock is required under applicable law to 
approve and adopt the Merger Agreement. All shares of GCS Common Stock which 
are entitled to vote and are represented at the Special Meeting by properly 
executed proxies received and not duly and timely revoked will be voted at 
the Special Meeting in accordance with the instructions contained therein. In 
the absence of contrary instructions, such shares will be voted "FOR" the 
approval and adoption of the Merger Agreement. The directors and executive 
officers of GCS, collectively beneficially own 131,708 shares of GCS Common 
Stock, including shares issuable pursuant to exercised options (approximately 
81.7% of the outstanding shares of GCS Common Stock as of the Record 
Date). See "THE MERGER - Interests of Certain Persons in the Merger."

                  This section of this Proxy Statement/Prospectus describes 
certain aspects of the Merger. To the extent that it relates to the Merger 
Agreement, the following description is not complete and is qualified in its 
entirety by reference to the Merger Agreement, a copy of which is included in

reference. All stockholders of GCS are urged to read the Merger Agreement in

GENERAL

                  The Merger Agreement provides for a business combination 
between Ecolab and GCS pursuant to which, subject to the satisfaction or 
waiver of the conditions therein, at the effective time, Merger Sub will be 
merged with and into GCS, and GCS will thereby become a wholly-owned 
subsidiary of Ecolab. The transaction is intended to qualify as a purchase 
for accounting and financial reporting purposes.

                  As a consequence of the Merger, each share of GCS Common 
Stock issued and outstanding immediately prior to the Effective Time (other 
than shares of GCS Common Stock held in treasury or by Ecolab or its 
affiliates) will be converted into and exchangeable for the right to receive 
the Merger Consideration. Each share of Ecolab Common Stock issued in the 
Merger will have attached thereto an appropriate number of associated 
preferred stock purchase rights. Each outstanding share of Ecolab Common 
Stock will remain outstanding and unaffected by the Merger.

                                       11
<PAGE>

                  No fractional shares of Ecolab Common Stock will be issued 
in the Merger. Instead, the Merger Agreement provides that each holder of GCS 
Common Stock who would otherwise have been entitled to receive a fractional 
share of Ecolab Common Stock will be entitled to receive, in lieu thereof, 
one additional share of Ecolab Common Stock.

BACKGROUND OF THE MERGER

                  In January 1997, Mr. James Miller, former Vice President of 
Ecolab, and Mr. James Salter, a divisional Vice President of Ecolab, met with 
Mr. Wesley B. Tyler, President of GCS, to discuss certain service issues 
relating to service provided by GCS to Jackson MSC, Inc. ("Jackson"), a 
subsidiary of Ecolab. During this meeting, Mr. Miller and Mr. Salter first 
discussed the potential for a business combination involving Ecolab and GCS.

                  In May 1997, Messrs. Miller, Salter and Tyler and Mr. 
Michael Hickey of Ecolab met again to discuss several issues including the 
possibility of expanding the service that GCS was providing to Jackson, the 
dish machine service relationship between GCS and Ecolab's Institutional 
Division and the possibility of a business combination involving the two 
companies. As a result of this meeting, on May 23, 1997, Ecolab and GCS 
entered into a confidentiality agreement.

                  Following this meeting, from time to time, the parties 
discussed their respective businesses, management philosophies, operating 
strategies and competitive goals. As a result of these on-going discussions, 
on July 24, 1997, Ecolab submitted a letter of interest to GCS indicating 
Ecolab's interest in a potential acquisition of GCS. Based upon Ecolab's 
expressed interest, discussions continued through August and September. 
During this period, the Ecolab parties visited several GCS locations to 
observe the customer service, operations, research and development and other 
business operations of the Company.
   
                  In September 1997, the GCS Board authorized Mr. Tyler to 
discuss terms of a potential merger with Ecolab with members of Ecolab 
management. At this meeting the GCS Board also appointed a Special Committee 
of the GCS Board to assist Mr. Tyler in both the negotiations with Ecolab and 
the appointment of an investment advisor.
    
                  In September 1997, the Special Committee of the GCS Board 
interviewed Carter Capital Corporation ("Carter") and Brown Brothers Harriman 
("Brown Brothers") for the purpose of selecting one of them to assist the 
Board in evaluating certain strategic alternatives for GCS. On October 28, 
1997, Mr. Tyler met with representatives of Brown Brothers to investigate 
strategic alternatives for GCS, including a possible initial public offering 
of GCS Common Stock, obtaining new capital from a venture partner, selling 
GCS by auction or continuing merger discussions with Ecolab. The parties 
concurrently discussed the valuation of GCS and the relevant factors to be 
considered in such valuation.

                  In November 1997, the parties met at La Guardia Airport in 
New York City and agreed to the major terms of a merger. A letter of intent 
was subsequently signed on November 26, 1997.

                  The letter of intent, dated November 26, 1997, required GCS 
to negotiate exclusively with Ecolab for a period of 90 days with respect to 
a possible acquisition of GCS. Following execution of this letter agreement, 
discussions continued to be held by senior management of Ecolab and GCS with 
respect to the proposed combination.

                  In December 1997, the transaction was submitted to, and 
approved by, the Ecolab Board of Directors. Thereafter, due diligence and 
document preparation continued through the beginning of 1998.

                  On February 3, 1998, the GCS Board retained Carter to 
provide a fairness opinion regarding the merger.

                  On February 24, 1998, GCS and Ecolab modified the letter of 
intent to extend the exclusive negotiations period provided for in such 
letter agreement to a period of 180 days.

   
                  On March 1, 1998, upon completion of the negotiations, 
Carter rendered its oral opinion to the GCS Board (which opinion was 
subsequently delivered in written form to the GCS Board) that the 
consideration to be received by the GCS stockholders was fair to such 
stockholders from a financial point of view, subject to receiving the 
complete merger agreement and employment contracts. See "THE MERGER - 
Fairness Opinion." Following the delivery of such opinion, the GCS Board 
unanimously determined that the Merger was in the best interests of the GCS 
stockholders and unanimously recommended approval of the Merger Agreement.  
    

                  The Merger Agreement was executed by authorized officers of 
Ecolab and GCS on May 12, 1998.

                  The execution of the Merger was publicly announced on 
May 18, 1998.

APPROVAL BY THE ECOLAB BOARD AND ECOLAB'S REASONS FOR THE MERGER

                  In connection with the Merger, after consulting with 
management, the Ecolab Board concluded that the Merger was in the best 
interests of Ecolab for the reasons, among others, set forth below.

                  The Merger is consistent with Ecolab's "Circle the 
Customer" strategy. Following an acquisition of GCS, Ecolab would be 
immediately able to provide enhanced service capabilities to its existing 
customer base in the hotel, restaurant and food service industries. In 
addition, Ecolab expects to achieve synergies in the Merger by, among other 
things, leveraging sales and marketing efforts of its territory managers and 
its corporate accounts group with its existing customer base.

                  The Merger presents Ecolab with growth opportunities. GCS 
currently has branches in 22 of the largest 30 metropolitan areas in the 
United States. Growth in this market could be achieved by expanding the GCS 
business geographically into metropolitan areas not currently served by GCS, 
by selling GCS' services to Ecolab's corporate accounts and by providing 
additional service offerings. Because the acquisition of GCS is consistent 
with Ecolab's "Circle the Customer" strategy and presents opportunities for 
synergies and growth, Ecolab believes that the Merger is in the best 
interests of its stockholders.

APPROVAL BY THE GCS BOARD AND GCS' REASONS FOR THE MERGER

                  After consulting with management, the GCS Board concluded 
that the Merger is in the best interests of GCS and its stockholders. In 
approving the Merger Agreement, the GCS Board considered a variety of 
factors, although it did not assign any relative or specific weight to any 
factor. Among those considered were the following:

         -        Ecolab offered acquisition consideration in an amount which
                  the GCS Board deemed to be attractive. In part, the GCS Board
                  based this determination upon the advice of its investment
                  advisor that the transaction was fair from a financial point
                  of view. See "THE MERGER- Fairness Opinion."

         -        The Merger is structured to provide tax-free reorganization
                  treatment to GCS stockholders. The GCS Board considers this to
                  be a significant benefit in view of the relatively low tax
                  basis in the respective shares owned by many GCS stockholders
                  as compared to the acquisition value of such shares.

         -        Stockholders of GCS will receive shares of Ecolab Common
                  Stock, which has a trading market on the NYSE and the PCX.
                  There is currently no independent market for GCS Common Stock.

         -        The GCS Board believes that Ecolab Common Stock will provide a
                  good opportunity for potential future appreciation, although
                  no assurance can be given that such potential future
                  appreciation will be realized.

         -        Affiliation with a larger company may provide an opportunity
                  to realize economies of scale and increased efficiencies of
                  operations, to the benefit of stockholders and customers.
                  Affiliation with Ecolab may also enhance the development of
                  new products and services, as changes in the commercial food
                  equipment industry are becoming increasingly difficult to
                  address by small companies.

         -        Growth of GCS without affiliation with a larger parent company
                  will likely be somewhat limited because of GCS' need for
                  increasing capital resources to support that growth. Without
                  such a combination, the GCS Board believes it will be
                  necessary to obtain additional capital resources beyond those
                  which can be obtained from operations, in order to achieve a
                  size which the GCS Board believes is necessary to maintain GCS
                  as a viable independent entity.

                  FOR THESE REASONS, THE GCS BOARD OF DIRECTORS RECOMMENDS THAT
STOCKHOLDERS VOTE "FOR" THE MERGER AND TO APPROVE THE TRANSACTIONS CONTEMPLATED
BY THE MERGER AGREEMENT.

FAIRNESS OPINION

                  On February 3, 1998, the GCS Board entered into a letter 
agreement with Carter Capital Corporation ("Carter") pursuant to which Carter 
agreed to render a fairness opinion in connection with the Merger.

                                       13
<PAGE>

Carter delivered a verbal opinion to the GCS Board on March 11, 1998 that the 
consideration to be paid to the stockholders of GCS was fair, from a 
financial point of view, subject to receiving the completed merger agreement 
and employment contracts (the "Opinion").

   
                  Carter subsequently delivered a written copy of its Opinion 
to the GCS Board. The Opinion is based upon a review of the financial and 
other information reviewed by Carter in rendering its verbal opinion along 
with a review of the information set forth in this Proxy Statement/Prospectus 
and the financial results for GCS and Ecolab since 1994 and 1995, 
respectively. The full text of the Opinion, which sets forth assumptions 
made, matters considered, and limitations on the review undertaken, is 
attached as Annex III to this Proxy Statement/Prospectus. GCS stockholders 
are urged to read the Opinion in its entirety.
    

                  During the course of its engagement, and as a basis for 
arriving at the Opinion, Carter reviewed and analyzed material bearing upon 
the financial and operating condition of GCS and Ecolab and material prepared 
in connection with the Merger, including, among other things, the following: 
(i) the Merger Agreement and related documents; (ii) certain 
publicly-available information concerning Ecolab, including financial 
statements and reports of condition and income for each of the three fiscal 
years ended December 31, 1997, 1996 and 1995; (iii) the nature and terms of 
recent sale and merger transactions involving similar companies that Carter 
considered relevant; (iv) historical and current market data for Ecolab 
Common Stock; and (v) financial and other information provided to Carter by 
management of GCS and its independent auditors. In addition, Carter conducted 
meetings with selected members of senior management of GCS and the entire GCS 
Board for the purpose of reviewing the future prospects of GCS. Carter 
evaluated the pro forma ownership of Ecolab Common Stock by GCS stockholders, 
relative to the pro forma contribution of the assets, liabilities, equity, 
and earnings of GCS to the pro forma company. Carter also took into account 
its experience in other transactions, as well as its knowledge of the 
industry and its general experience in securities valuation.

                  In preparing the Opinion, Carter assumed and relied upon 
the accuracy and completeness of all financial and other information reviewed 
by it for purposes of the Opinion, and did not independently verify such 
information or undertake an independent evaluation or appraisal of the assets 
or liabilities of GCS or Ecolab, nor was it furnished with any such 
evaluation or appraisal. Carter assumed and relied upon the senior management 
of GCS as to the reasonableness and achievability of the financial and 
operating forecasts and assumptions utilized by Carter in its analyses. The 
Opinion is necessarily based on economic, market and other conditions as in 
effect on, and the information made available to Carter as of, the date of 
this Proxy Statement/Prospectus.

                  The Opinion is directed only to the fairness of the 
financial consideration to be paid to the GCS Stockholders and does not 
constitute a recommendation to any GCS stockholder as to how each stockholder 
should vote at the Special Meeting or as to the advisability of retaining or 
disposing of shares of Ecolab Common Stock received pursuant to the Merger.

GCS STOCKHOLDER APPROVAL
   
                  The GCS Board has unanimously approved the Merger Agreement 
and the transactions contemplated thereby. In order to effect the Merger, the 
Merger Agreement must also be approved and adopted by the affirmative vote of 
a majority of the outstanding shares of GCS Common Stock entitled to vote 
thereon. A Special Meeting of GCS stockholders has been scheduled to be held 
at the offices of Edwards & Angell on July 10, 1998.
    
ECOLAB STOCKHOLDER APPROVAL

                  The Merger does not require the approval of the Ecolab 
stockholders. Ecolab stockholders will not have dissenters' appraisal rights 
in connection with the Merger.

THE MERGER

                  The Merger Agreement provides that, on the second business day
following the satisfaction or waiver of the conditions to each party's
obligation to consummate the Merger or as otherwise agreed, Merger Sub will be
merged with and into GCS in accordance with the DGCL, the separate corporate
existence of Merger Sub will cease and GCS will continue as the Surviving
Corporation in the Merger.

                                       14

<PAGE>

CLOSING; EFFECTIVE TIME

                  The closing of the transactions contemplated by the Merger 
Agreement will take place two business days following the satisfaction or 
waiver of the conditions set forth in the Merger Agreement, or as otherwise 
agreed by the parties (the "Closing Date"). The Merger will become effective 
upon the filing of a Certificate of Merger with the Secretary of State of the 
State of Delaware in accordance with the DGCL (the "Effective Time"). Such 
filings will be made on the Closing Date.

CONVERSION OF SHARES; FRACTIONAL SHARES

                  In the Merger, each share of GCS Common Stock outstanding 
prior to the Effective Time, including shares issued upon exercise of 
outstanding options prior to or on the Closing Date, will be converted into 
the right to receive a number of shares of Ecolab Common Stock equal to (i) 
the amount equal to the Estimated Closing Value (as hereinafter defined) 
divided by the Average Stock Price (as hereinafter defined) divided by (ii) 
161,143, subject to further post-closing adjustments (the "Merger 
Consideration"). The "Estimated Closing Value" is equal to $26,363,671 plus 
or minus, as appropriate, the Closing Adjustment Amount, subject to further 
post-closing adjustment. The "Closing Adjustment Amount" means (A) if the net 
worth of GCS as reflected on the Estimated Closing Balance Sheet (as defined 
in the Merger Agreement) is less than $5,800,000, the Estimated Closing Value 
shall be reduced by an amount equal to the amount by which such net worth is 
less than $5,800,000; or (B) if the net worth of GCS as reflected on the 
Estimated Closing Balance Sheet is greater than $5,800,000, then the 
Estimated Closing Value shall be increased by an amount equal to the amount 
by which such net worth exceeds $5,800,000. The Merger Consideration is 
subject to further adjustment after Closing based upon any changes in the net 
worth of GCS in the final closing-day balance sheet (to be prepared within 60 
days after the Closing) from the net worth in the estimated closing-day 
balance sheet. The "Average Stock Price" means the average per share closing 
prices, as reported on the NYSE Composite Tape, of shares of Ecolab Common 
Stock during the period comprised of the 20 consecutive trading days ending 
on the fourth trading day prior to the closing date of the Merger.

                  No fractional shares of Ecolab Common Stock will be issued 
in the Merger. Instead, each record holder of GCS Common Stock who would 
otherwise have been entitled to receive a fraction of a share of Ecolab 
Common Stock upon surrender of certificates representing GCS Common Stock for 
exchange will, upon surrender of such certificates, be entitled to receive 
one additional share of Ecolab Common Stock.

ACCOUNTING TREATMENT

                  The Merger is expected to be accounted for as a purchase in 
accordance with generally accepted accounting principles.

EXCHANGE OF CERTIFICATES

                  Subject to the terms of the Escrow Agreement described 
herein, upon surrender of each certificate representing shares of GCS Common 
Stock, First Chicago Trust Company of New York (the "Exchange Agent") will 
issue to the holder of such certificate, as soon as practicable after the 
Effective Time, his or her shares of Ecolab Common Stock. At that time, such 
certificate representing shares of GCS Common Stock will be cancelled. Until 
so surrendered and exchanged, each such certificate representing shares of 
GCS Common Stock will represent solely the right to receive shares of Ecolab 
Common Stock pursuant to the Merger Agreement. 10% of the Ecolab shares to be 
issued to each GCS stockholder will be withheld and deposited in the Escrow 
Fund (as hereinafter defined). See "Indemnification Obligations."

                  No dividends or other distributions declared or made after 
the Effective Time with respect to shares of Ecolab Common Stock will be paid 
to the holder of any unsurrendered certificate representing GCS Common Stock 
until the holder surrenders such certificate in accordance with the 
provisions of the Merger Agreement.

                  At the Effective Time, all shares of GCS Common Stock that 
are owned by GCS as treasury stock will be cancelled and retired and will 
cease to exist, and no payment or other consideration will be made in respect 
thereof. See "Indemnification Obligations."

<PAGE>

                  The obligations of GCS to consummate the Merger are also 
subject to satisfaction or waiver by GCS of certain conditions, including (i) 
each obligation of Ecolab and Merger Sub under the Merger Agreement must have 
been performed in all material respects; (ii) Ecolab's and Merger Sub's 
representations and warranties contained in the Merger Agreement must be true 
in all material respects as of the Effective Time (except to the extent such

TERMINATION

                  The Merger Agreement may be terminated (i) by the mutual 
consent of the parties; (ii) by either party after November 30, 1998 if the 
Merger has not occurred as a result of failure to satisfy any condition to 
the Merger or (iii) by either party upon material breach of a representation, 
warranty or covenant by the other party. In the event that the Merger 
Agreement is terminated other than pursuant to a breach by Ecolab or Merger Sub 
of any representations or warranties or a failure by Ecolab or Merger Sub to 
comply with the terms of the Merger Agreement, and the stockholders of GCS 
fail to approve the Merger, the Company shall pay Ecolab a termination fee of 
$900,000.

TREATMENT OF GCS OPTIONS

                  The Merger Agreement provides that each GCS option awarded 
under any GCS stock option plan which remains unexercised must be exercised 
prior to the Effective Time. Each unexpired and unexercised GCS option that 
is outstanding prior to the Effective Time will be cancelled and all rights 
thereunder extinguished. No stock options are being granted in connection 
with the Merger.

INDEMNIFICATION OBLIGATIONS

                  The Merger Agreement provides that GCS and Mr. Tyler will 
indemnify and hold harmless Ecolab and Merger Sub, their officers, directors 
and affiliates against any and all losses, liabilities, claims and other 
costs and expenses arising in connection with any breach or inaccuracy of any 
representation or warranty of GCS, Mr. Tyler or any claim, suit or other 
action brought by any stockholder of GCS relating to the transactions 
contemplated by the Merger Agreement or any claim, suit or other proceeding 
brought by or on behalf of certain former officers, employees or stockholders 
of GCS. The indemnification obligations of GCS and Mr. Tyler are subject to 
certain limitations as described below.
   
                  Ecolab, GCS, Mr. Tyler (as Stockholder Representative) and 
the Norwest Bank Minnesota National Association ("Norwest" or the "Escrow 
Agent") will enter into the Escrow Agreement (as hereinafter defined) 
providing for the escrow of 10% of the aggregate Merger Consideration in the 
form of Ecolab Common Stock to be paid to the stockholders of GCS to secure 
the indemnity obligations of GCS and Mr. Tyler (the "Escrow Amount"). See 
"Interests of Certain Persons in the Merger." The indemnification obligations 
are limited to the Escrow Amount. Mr. Tyler's indemnification obligations are 
limited to his pro rata share of the Escrow Amount plus any amounts in excess 
of the total Escrow Amount up to a maximum amount of one-half of the total 
Merger Consideration. Neither GCS nor Mr. Tyler shall be liable for any 
indemnification obligations, other than those arising from fraud or 
third-party claims, unless and until such obligations exceed $150,000, or 
$10,000 where such indemnification obligations arise from claims that relate 
to certain former officers, employees or stockholders. In the event that 
Ecolab, in its sole and absolute discretion, elects to pursue any claims it 
may have against certain former officers or employees, then 50% of any 
recovery obtained (net of all costs associated with such recovery) will be 
paid to the GCS stockholders. Generally, indemnification claims must be 
brought within two years after the Closing or they lapse. With respect to 
certain indemnification claims, the period within which they must be brought 
is greater than two years.
    
INTERESTS OF CERTAIN PERSONS IN THE MERGER

                  In considering the recommendation of the GCS Board with 
respect to the Merger, GCS stockholders should be aware that certain members 
of GCS management and its Board of Directors have certain interests in 
connection with the Merger that are in addition to the interests of GCS 
stockholders generally. The Board of Directors of GCS was aware of these 
interests and considered them, among other matters, in approving the Merger 
Agreement and the transactions contemplated thereby, including the Merger.

                  GCS and Mr. Tyler have, pursuant to the Merger Agreement, 
agreed to indemnify Ecolab, its directors, officers and affiliates against 
certain losses, claims or liabilities arising in connection with the Merger. 
10% of the aggregate consideration paid to the GCS Stockholders in the Merger 
will be placed in escrow to secure the indemnity obligation of GCS pursuant 
to the form of Escrow Agreement between Ecolab, GCS, Mr. Tyler (as 
Stockholder Representative) and Norwest, as Escrow Agent (the "Escrow 
Agreement") as set forth in Exhibit C to the Merger Agreement. The 
indemnification obligations of GCS and Mr. Tyler are subject to

                                       17
<PAGE>

certain limitations. No indemnification obligation for breach of a 
representation or warranty incurred arises until the amount of any losses 
with respect thereto exceed $150,000, or $10,000 for indemnification 
obligations which relate to claims by certain officers, employees or 
stockholders. There is no minimum threshold with respect to any fraudulent 
breach or certain other indemnification obligations. GCS' obligations are 
limited in amount to the Escrow Amount. Mr. Tyler, in addition to his pro 
rata share of the Escrow Amount, is solely responsible for indemnification 
claims in excess of the amount of the Escrow Amount up to a maximum liability 
of one-half of the Merger Consideration.

                  Ecolab and Mr. Tyler agreed to a form of employment, bonus 
and non-competition agreement (the "Tyler Agreement"), effective upon 
consummation of the Merger, to replace Mr. Tyler's current employment 
agreement with GCS. The Tyler Agreement is a three year contract with an 
annual base salary of $170,000 plus a bonus with a potential range from a 
minimum of 30% of base salary to a maximum of 60% of base salary. In 
addition, the Tyler Agreement provides for an annual "stay-pay" bonus of 
$80,000, payable $20,000 per quarter during each of the three years of the 
agreement.

DIRECTORS AND OFFICERS

                  Pursuant to the Merger Agreement, the directors and 
officers of Merger Sub at the Effective Time will be the directors and 
officers, respectively, of the Surviving Corporation following the Merger 
until their respective successors are elected or appointed.

CHARTER AND BYLAWS

                  Pursuant to the Merger Agreement, the certificate of 
incorporation and bylaws of Merger Sub in effect at the Effective Time will 
be the certificate of incorporation and bylaws, respectively, of the 
Surviving Corporation until thereafter amended as provided therein and by 
law, except that the name of the Surviving Corporation initially shall be 
"GCS Service, Inc." following the Merger.

DISSENTERS' RIGHTS

                  Holders of GCS Common Stock are entitled to appraisal 
rights under Section 262 of the DGCL. A person having a beneficial interest 
in GCS Common Stock held of record in the name of another person, such as a 
broker or nominee, must act promptly to cause the record holder to follow the 
steps summarized below properly and in a timely manner to perfect whatever 
appraisal rights the beneficial owner may have.

                  THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE 
LAW PERTAINING TO APPRAISAL RIGHTS UNDER THE DGCL AND IS QUALIFIED IN ITS 
ENTIRETY BY THE FULL TEXT OF SECTION 262, WHICH IS REPRINTED IN ITS ENTIRETY 
AS ANNEX II TO THIS PROXY STATEMENT/PROSPECTUS.

                  All references in Section 262 and in this summary to a 
"stockholder" are to the record holder of the GCS Common Stock as to which 
appraisal rights are asserted.

                  Under the DGCL, holders of GCS Common Stock who do not wish 
to accept the consideration provided for in the Merger Agreement and who 
follow the procedures set forth in Section 262 will be entitled to have their 
CGS Common Stock appraised by the Delaware Court of Chancery and to receive 
payment in cash of the "fair value" of such shares, exclusive of any element 
of value arising from the accomplishment or expectation of the Merger, 
together with a fair rate of interest, if any, as determined by such court.

                  Under Section 262, where a merger is to be submitted for 
approval at a meeting of stockholders, as in the case of the Special Meeting, 
the corporation, not less than 20 days prior to the meeting, must notify each 
of its stockholders entitled to appraisal rights that such appraisal rights 
are available and include in such notice a copy of Section 262. This Proxy 
State ment/Prospectus shall constitute such notice to the holders of GCS 
Common Stock and the applicable statutory provisions of the DGCL are attached 
to this Proxy Statement/Prospectus as Annex II. Any stockholder who wishes to 
exercise such appraisal rights, or who wishes to preserve his right to do so, 
should review the following discussion and Annex II carefully because failure 
to timely and properly comply with the procedures specified will result in 
the loss of appraisal rights under the DGCL.

                  A holder of GCS Common Stock wishing to exercise his 
appraisal rights must deliver to the Secretary of GCS before the vote on the 
Merger Agreement at the Special Meeting, a written demand for appraisal of 
his or her GCS Common Stock

                                       18

and must not vote his shares of stock in favor of approval and adoption of 
the Merger Agreement. Because a proxy which does not contain voting 
instructions will, unless revoked, be voted for approval and adoption of the 
Merger Agreement, a holder of GCS Common Stock who votes by proxy and who 
wishes to exercise his or her appraisal rights must (i) vote against approval 
and adoption of the Merger Agreement or (ii) abstain from voting on approval 
and adoption of the Merger Agreement. Neither voting (in person or by proxy) 
against, abstaining from voting on or failing to vote on the proposal to 
approve and adopt the Merger Agreement will constitute a written demand for 
appraisal within the meaning of Section 262. The written demand for appraisal 
must be in addition to and separate from any such proxy or vote. In addition, 
a holder of GCS Common Stock wishing to exercise his or her appraisal rights 
must hold of record such shares on the date the written demand for appraisal 
is made and must continue to hold such shares until the Effective Time.

                  Only a holder of record of GCS Common Stock is entitled to 
assert appraisal rights for the GCS Common Stock registered in that holder's 
name. A demand for appraisal should be executed by or on behalf of the holder 
of record, fully and correctly, as his or her name appears on the stock 
certificates. If the shares of GCS Common Stock are owned of record in a 
fiduciary capacity, such as by a trustee, guardian or custodian, execution of 
the demand should be made in that capacity, and if the shares of GCS Common 
Stock are owned of record by more than one person, as in a joint tenancy and 
tenancy in common, the demand should be executed by or on behalf of all joint 
owners. An authorized agent, including one or more joint owners, may execute 
a demand for appraisal on behalf of a holder of record; however, the agent 
must identify the record owner or owners and expressly disclose the fact 
that, in executing the demand, the agent is agent for such owner or owners. A 
record holder such as a broker who holds GCS Common Stock as nominee for 
several beneficial owners may exercise appraisal rights with respect to the 
GCS Common Stock held for one or more beneficial owners while not exercising 
such rights with respect to the GCS Common Stock held for other beneficial 
owners; in such case, the written demand should set forth the number of GCS 
Common Stock as to which appraisal is sought and when no number of GCS Common 
Stock is expressly mentioned the demand will be presumed to cover all GCS 
Common Stock held in the name of the record owner. Stockholders who hold 
their GCS Common Stock in brokerage accounts or other nominee forms and who 
wish to exercise appraisals rights are urged to consult with their brokers to 
determine the appropriate procedures for the making of a demand for appraisal 
by such a nominee. All written demands for appraisal should be delivered to 
the Secretary of GCS either in person or by mail (certified mail, return 
receipt requested, being the recommended form of transmittal addressed to him 
at GCS Service, Inc. 100 Mill Plain Road, Danbury, Connecticut 06811.

                  Within ten days after the Effective Time, the Surviving 
Corporation must send a notice as to the effectiveness of the Merger to each 
former stockholder of GCS who has made such a written demand for appraisal 
and who has not voted in favor of approval and adoption of the Merger 
Agreement. Within 120 days after the Effective Time, but not thereafter, the 
Surviving Corporation, or any stockholder who is entitled to appraisal rights 
under Section 262 and has complied with the requirements of Section 262, may 
file a petition in the Delaware Court of Chancery demanding a determination 
of the fair value of the GCS Common Stock. The Surviving Corporation is under 
no obligation to and has no present intention to file a petition in respect 
to the appraisal of the fair value of the GCS Common Stock. Accordingly, it 
is the obligation of the stockholders to initiate all necessary action to 
perfect their appraisal rights within the time prescribed in Section 262.

                  Within 120 days after the Effective Time, any stockholder 
who has complied with the requirements under Section 262 for exercise of 
appraisal rights will be entitled, upon written request, to receive from the 
Surviving Corporation a statement setting forth the aggregate number of GCS 
Common Stock with respect to which demands for appraisal have been received 
and which have not voted in favor of approval and adoption of the Merger 
Agreement, and the aggregate number of holders of such shares. Such 
statements must be mailed within ten days after a written request therefor 
has been received by the Surviving Corporation.

                  If a petition for appraisal is duly filed by a holder of 
GCS Common Stock and a copy thereof is delivered to the Surviving 
Corporation, the Surviving Corporation will then be obligated within 20 days 
to provide the Delaware Court of Chancery with a duly verified list 
containing the names and addresses of all holders of GCS Common Stock who 
have demanded appraisal of their shares. After notice to such holders of GCS 
Common Stock the Delaware Court of Chancery is empowered to conduct a hearing 
upon the petition to determine those holders of GCS Common Stock who have 
complied with Section 262 and who have become entitled to appraisal rights 
under that section. The Delaware Court of Chancery may require the holders of 
GCS Common Stock who have demanded payment for their shares to submit their 
stock certificates to the Register in Chancery for a notation thereon of the 
pendency of the appraisal proceedings; and if any stockholder fails to comply 
with such direction, the Delaware Court of Chancery may dismiss the 
proceedings as to such stockholder.

                  After determining the stockholders entitled to an 
appraisal, the Delaware Court of Chancery will appraise the "fair value" of 
their GCS Common Stock, exclusive of any element of value arising from the 
accomplishment or expectation of the Merger, together with a fair rate of 
interest, if any, to be paid upon the amount determined to be the fair value. 
Stockholders considering

                                       19
<PAGE>

seeking appraisal should be aware that the fair value of their GCS Common 
Stock as determined under Section 262 could be more than, the same as or less 
than the consideration they would receive pursuant to the Merger Agreement if 
they did not seek appraisal of their GCS Common Stock and that investment 
banking opinions as to fairness from a financial point of view are not 
necessarily opinions as to fair value under Section 262. The Delaware Supreme 
Court has stated that "proof of value by any techniques or methods which are 
generally considered acceptable in the financial community and otherwise 
admissible in court" should be considered in the appraisal proceedings. In 
addition, Delaware courts have decided that the statutory appraisal remedy, 
depending on factual circumstances, may or may not be a dissenter's exclusive 
remedy. The Court will also determine the amount of interest, if any, to be 
paid upon the amounts to be received by persons whose GCS Common Stock have 
been appraised. The costs of the action may be determined by the Court and 
taxed upon the parties as the Court deems equitable. The Court may also order 
that all or a portion of the expenses incurred by any stockholder in 
connection with an appraisal, including, without limitation, reasonable 
attorneys' fees and the fees and expenses of experts utilized in the 
appraisal proceeding, be charged pro rata against the value of all of the GCS 
Common Stock entitled to appraisal.

                  Any holder of shares who has duly demanded an appraisal in 
compliance with Section 262 will not, after the Effective Time, be entitled 
to vote the GCS Common Stock subject to the appraisal demand for any purpose 
or be entitled to the payment of dividends or other distributions on those 
shares (except dividends or other distributions, other than the Merger 
Consideration, payable to holders of record of GCS Common Stock as of a date 
prior to the Effective Time).

                  If any stockholder who demands appraisal of his or her 
shares of GCS Common Stock under Section 262 fails to perfect, or effectively 
withdraws or loses, his or her right to appraisal as provided in the DGCL, 
the GCS Common Stock of such stockholder will be converted into the right to 
receive the Merger Consideration in accordance with the Merger Agreement. A 
stockholder will fail to perfect, or effectively lose or withdraw, his or her 
right to appraisal if he votes for approval and adoption of the Merger 
Agreement (or submits a proxy without voting instructions) or if no petition 
for appraisal is filed within 120 days after the Effective Time of the Merger 
or if the stockholder delivers to GCS (or, after the Effective Time, to the 
Surviving Corporation) a written withdrawal of his or her demand for 
appraisal and an acceptance of the Merger, except that any such attempt to 
withdraw made more than 60 days after the Effective Time will require the 
written approval of the Surviving Corporation.

                  FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 OF THE 
DGCL FOR PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.

                  CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

                  The following is a discussion of the material federal 
income tax consequences of the Merger under existing federal income tax law, 
which is subject to change, possibly retroactively. This discussion assumes 
that stockholders hold GCS Common Stock as a capital asset as of the 
Effective Time of the Merger. This discussion does not discuss all aspects of 
federal income taxation which may be relevant to particular stockholders in 
light of their personal circumstances, such as stockholders whose stock was 
acquired pursuant to the exercise of an employee stock option or otherwise as 
compensation, stockholders who are subject to special treatment under the 
federal income tax laws (for example, financial institutions, insurance 
companies, tax-exempt organizations, broker-dealers and foreign persons) or 
stockholders who exercise dissenters' rights under the DGCL (see "THE MERGER 
- - Dissenters' Rights"). This discussion also does not address any aspects of 
state, local or foreign tax law. No opinions of counsel or rulings from the 
Internal Revenue Service have been or will be sought with respect to any tax 
matters relating to the Merger. EACH STOCKHOLDER IS ADVISED TO CONSULT HIS OR 
HER OWN TAX ADVISOR AS TO THE FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND 
OTHER TAX CONSEQUENCES OF THE MERGER.

                  The Merger is intended to qualify as a reorganization 
within the meaning of Section 368(a) of the Code. Assuming the Merger does so 
qualify, then (i) no gain or loss will be recognized by Ecolab or GCS for 
Federal income tax purposes as a result of the Merger; and (ii) the Federal 
income tax consequences to a holder of GCS Common Stock will depend on 
whether the stockholder receives only Ecolab Common Stock or receives, as a 
result of any potential payments for claims as described in "THE MERGER - 
Indemnification Obligations," a combination of Ecolab Common Stock and cash 
pursuant to the Merger.

                  A holder of GCS Common Stock who receives only shares of 
Ecolab Common Stock in the Merger will recognize no gain or loss as a result 
of the exchange.

                  Except as described below under "-Additional 
Considerations," a stockholder who receives a combination of Ecolab Common 
Stock and cash in exchange for GCS Common Stock will generally recognize 
capital gain, but not loss, for federal income

                                       20
<PAGE>

tax purposes in an amount equal to the lesser of (i) the amount of gain 
realized (i.e., the excess of the amount of cash and the fair market value of 
Ecolab Common Stock received over the tax basis of such GCS Common Stock) and 
(ii) the amount of cash received.

                  The aggregate tax basis of the Ecolab Common Stock received 
by a stockholder will be the same as the aggregate tax basis of the GCS 
Common Stock surrendered in exchange therefor pursuant to the Merger, 
decreased by the total amount of cash received and increased by the amount of 
gain recognized. The holding period of the Ecolab Common Stock will include 
the holding period of the GCS Common Stock surrendered in exchange therefor.

ADDITIONAL CONSIDERATIONS

                  With respect to stockholders who receive cash in the 
Merger, it is possible that, under certain circumstances, the gain recognized 
could be treated as dividend income rather than capital gain unless the 
requirements of Section 302 of the Code are satisfied. In order to determine 
whether those requirements are satisfied, a stockholder is treated as 
receiving solely Ecolab Common Stock in the Merger (instead of the cash 
actually received) and then receiving cash from Ecolab in a hypothetical 
redemption of those shares. The hypothetical redemption will satisfy the 
requirements under Section 302 if it either (i) is "not essentially 
equivalent to a dividend" or (ii) has the effect of a "substantially 
disproportionate" redemption of Ecolab Common Stock. Whether such 
hypothetical redemption of Ecolab Common Stock is "not essentially equivalent 
to a dividend" depends on the individual facts and circumstances of each 
stockholder but in any event must result in a meaningful reduction of a 
stockholder's proportionate stock interest in Ecolab. Generally, in the case 
of a GCS stockholder whose stock interest in Ecolab (relative to the total 
number of Ecolab shares outstanding) is minimal, and who exercises no control 
over the affairs of Ecolab, any actual reduction in proportionate interest 
will be treated as "meaningful." Alternatively, the hypothetical redemption 
of the Ecolab Common Stock will be "substantially disproportionate" if the 
ratio which the Ecolab Common Stock (and any other Ecolab voting stock) owned 
by the stockholder after the hypothetical redemption bears to all of the 
voting stock of Ecolab at such time is less than 80% of the ratio which the 
Ecolab Common Stock (and any other Ecolab voting stock) hypothetically owned 
by the stockholder after the Merger but before the redemption bears to all of 
the voting stock of Ecolab at such time. In applying the foregoing tests, 
there must be taken into account not only actual ownership of stock but also 
stock constructively owned by a shareholder by reason of certain attribution 
rules under Section 318 of the Code. If the receipt of cash is treated as 
having the effect of a dividend, only the portion of the recognized gain that 
is not in excess of the shareholder's ratable share of the accumulated 
earnings and profits of Ecolab will be taxable as a dividend. BECAUSE OF THE 
COMPLEXITY OF THESE RULES, EACH HOLDER OF GCS COMMON STOCK WHO RECEIVES A 
COMBINATION OF CASH AND ECOLAB COMMON STOCK IN THE MERGER OR WHO OTHERWISE 
BELIEVES THESE RULES MIGHT APPLY TO HIM OR HER IS PARTICULARLY URGED TO 
CONTACT HIS OR HER OWN TAX ADVISOR.

WITHHOLDING

                  Unless an exemption applies, the Escrow Agent will be 
required to withhold, and will withhold, 31% of any cash payments to which a 
stockholder or other payee is entitled pursuant to the Merger, unless the 
stockholder or other payee provides his or her tax identification number 
(social security number or employer identification number) and certifies that 
such number is correct. Each stockholder and, if applicable, each other payee 
is required to complete and sign the Form W-9 that will be included as part 
of the transmittal letter to avoid backup withholding (or IRS Form W-8 if the 
stockholder is a nonresident alien or foreign entity), unless an applicable 
exemption exists and is proved in a manner satisfactory to Ecolab and the 
Escrow Agent.

                  EACH STOCKHOLDER IS STRONGLY ADVISED TO CONSULT HIS OR HER 
OWN TAX ADVISOR AS TO PARTICULAR FACTS AND CIRCUMSTANCES WHICH MAY BE UNIQUE 
TO SUCH STOCKHOLDER AND ALSO AS TO ANY ESTATE, GIFT, STATE, LOCAL OR FOREIGN 
TAX CONSEQUENCES ARISING OUT OF THE MERGER.

                  The following summaries of the terms of Ecolab Common Stock 
and Ecolab Preferred Stock are not complete and are qualified in their 
entirety by reference to the restated certificate of incorporation (the 
"Ecolab Restated Certificate of Incorporation"), bylaws (the "Ecolab Bylaws") 
and the DGCL. For a discussion of the material differences between the rights 
of holders of GCS Common Stock and the rights of holders of Ecolab Common 
Stock, see "COMPARISON OF STOCKHOLDER RIGHTS."

ECOLAB COMMON STOCK

                  Ecolab is authorized to issue 200,000,000 shares of Ecolab 
Common Stock. As of April 30, 1998, there were outstanding 128,752,964 shares 
of Ecolab Common Stock. The holders of Ecolab Common Stock are entitled to 
one vote for each share held. The holders of Ecolab Common Stock do not have 
cumulative voting rights. Subject to the rights of holders of preferred stock 
of Ecolab ("Ecolab Preferred Stock"), holders of Ecolab Common Stock are 
entitled to receive the assets and funds of Ecolab available for distribution 
to stockholders upon liquidation, dissolution or winding up.

                  The holders of Ecolab Common Stock do not have any 
preemptive rights to acquire any shares or other securities of any class that 
may at any time be issued, sold or offered for sale by Ecolab. The holders of 
Ecolab Common Stock have no conversion rights, and the Ecolab Common Stock is 
not subject to redemption by either Ecolab or a stockholder.

                  The holders of Ecolab Common Stock own one-half of one 
preferred stock purchase right (each, a "Right") for each outstanding share 
of Ecolab Common Stock. The Rights are inseparable from the Ecolab Common 
Stock unless and until certain events or determinations occur which result in 
the concentration of ownership of a substantial amount of Ecolab Common Stock 
with one stockholder or group of affiliated Stockholders. Upon separation, 
the Rights entitle certain holders to the right to purchase Preferred Stock 
of Ecolab or to receive additional shares of Common Stock. The Rights expire 
March 11, 2006, unless earlier redeemed, exercised or repealed. For a more 
complete description of the terms of the Rights, see "COMPARISON OF 
STOCKHOLDER RIGHTS - Share Purchase Rights" and Ecolab's Report on Form 
8-A/A, incorporated by reference herein.

                  The Ecolab Common Stock is listed and traded on the NYSE 
and the PCX under the symbol "ECL."

ECOLAB PREFERRED STOCK

                  Ecolab is authorized to issue up to 15,000,000 shares of 
Ecolab Preferred Stock. As of April 30, 1998, there are no outstanding shares 
of Ecolab Preferred Stock.

                        DESCRIPTION OF GCS CAPITAL STOCK

                  The following summary of the terms of GCS Common Stock does 
not purport to be complete and is qualified in its entirety by reference to 
the certificate of incorporation (the "GCS Certificate of Incorporation"), 
the bylaws (the "GCS Bylaws") and the DGCL. For a discussion of the material 
differences between the rights of holders of GCS Common Stock and the rights 
of holders of Ecolab Common Stock, see "COMPARISON OF STOCKHOLDER RIGHTS."

                  GCS is authorized to issue 500,000 shares of GCS Common 
Stock. As of May 12, 1998, there were outstanding 147,118 shares of GCS 
Common Stock and options outstanding for the purchase of 14,025 shares of GCS 
Common Stock. The holders of GCS Common Stock are entitled to one vote for 
each share held and do not have cumulative voting rights. The holders of GCS 
Common Stock are entitled to receive the assets and funds of GCS available 
for distribution to stockholders upon liquidation, dissolution or winding up.

                  The holders of GCS Common Stock do not have any preemptive 
rights to acquire any shares or other securities of any class that may at any 
time be issued, sold or offered for sale by GCS. The holders of GCS Common 
Stock have no conversion rights, and the GCS Common Stock is not subject to 
redemption by either GCS or a stockholder.

                  The GCS Common Stock is not listed or traded on any public 
stock exchange.

                        COMPARISON OF STOCKHOLDER RIGHTS

                  Ecolab and GCS are both organized under the laws of the 
State of Delaware. Any differences, therefore, between the rights of the 
Ecolab stockholders and the rights of the GCS stockholders arise solely from 
differences between each corporation's certificate of incorporation and 
bylaws.

                  The following summary sets forth certain material 
differences between the rights of the Ecolab stockholders and the rights of 
the GCS stockholders. This summary is not a complete description of the 
differences between the rights of the Ecolab stockholders and the rights of 
the GCS stockholders and is qualified in its entirety by reference to the 
Ecolab Restated Certificate of Incorporation and the Ecolab Bylaws and to the 
GCS Certificate of Incorporation and the GCS Bylaws.

AUTHORIZED CAPITAL STOCK

                  The authorized capital stock of Ecolab consists of 
200,000,000 shares of Ecolab Common Stock and 15,000,000 shares of Ecolab 
Preferred Stock. As of April 30, 1998, there were 128,752,964 shares of 
Ecolab Common Stock and no shares of Ecolab Preferred Stock issued and 
outstanding. The authorized capital stock of GCS consists of 500,000 shares 
of GCS Common Stock. As of May 12, 1998, there were 147,118 shares of GCS 
Common Stock issued and outstanding.

SHARE PURCHASE RIGHTS

                  On February 24, 1996, the Board of Directors of Ecolab 
declared a dividend distribution of one Right for each outstanding share of 
Ecolab's common stock, $1.00 par value (the "Common Stock"), to stockholders 
of record at the close of business on March 11, 1996 (the "Rights Record 
Date"). The Board of Directors of Ecolab also authorized the issuance of one 
Right for each share of Common Stock issued after the Rights Record Date and 
prior to the earliest of the Distribution Date (as defined below), the 
redemption of the Rights and the expiration of the Rights and, in certain 
circumstances, after the Distribution Date. Upon payment of the dividend at 
the close of business on the Rights Record Date, the Rights attached to all 
Common Stock certificates representing shares then outstanding, and no 
separate Rights Certificates (as defined below) were distributed. Except as 
set forth below and subject to adjustment as provided in the Rights Agreement 
(as defined below), each Right entitles the registered holder to purchase 
from Ecolab one one-hundredth of a share of Series A Junior Participating 
Preferred Stock (the "Preferred Stock"), at a purchase price of $115 per 
Right (the "Purchase Price"). The description and terms of the Rights are set 
forth in a Rights Agreement, dated as of February 24, 1996 (the "Rights 
Agreement"), between Ecolab and First Chicago Trust Company of New York, as 
Rights Agent.

                  On December 15, 1997, the Board of Directors of Ecolab 
declared a two-for-one stock split ("Stock Split"), which was effected in the 
form of a 100% stock dividend, payable on January 15, 1998 to the holders of 
record of shares of Common Stock at the close of business on December 26, 
1997. Upon payment of the Stock Split, each outstanding share of Common Stock 
became associated with one-half (1/2) of a Right and one-half (1/2) of a 
Right became attached to each share of Common Stock issued in connection with 
the Stock Split. Thereafter, until the Distribution Date, Ecolab will issue 
one-half (1/2) of a Right with each share of Common Stock that shall become 
outstanding so that all such shares will have attached Rights. One million 
(1,000,000) shares of Preferred Stock have been reserved for issuance upon 
exercise of the Rights.

                  The Rights will separate from the Common Stock upon the 
earliest of (i) 10 days following a public announcement that a person or 
group (an "Acquiring Person"), together with persons affiliated or associated 
with it, has acquired, or obtained the right to acquire, beneficial ownership 
of 15% or more of the outstanding shares of Common Stock (the "Stock 
Acquisition Date"), (ii) 10 business days (or such later date as the Board of 
Directors of Ecolab shall determine) following the commencement of a tender 
offer or exchange offer that would result in a person or group beneficially 
owning 15% or more of such outstanding shares of Common Stock, or (iii) 10 
business days following a determination by the Board of Directors of Ecolab 
that a person (an "Adverse Person"), alone or together with its affiliates 
and associates, has become the beneficial owner of more than 10% of the 
Common Stock and that (a) such beneficial ownership is intended to cause 
Ecolab to repurchase the Common Stock beneficially owned by such person or to 
cause pressure on Ecolab to take action or enter into transactions intended 
to provide such person with short-term financial gain under circumstances 
where the Board of Directors of Ecolab determines that the best long-term 
interests of Ecolab would not be served by taking such action or entering 
into such transactions at the time, or (b) such beneficial ownership is 
causing or reasonably likely to cause a material adverse impact on the 
business or prospects of Ecolab; provided, however, that the Board of 
Directors of Ecolab shall not declare any person to be an Adverse Person if 
such person has reported or is required to report its ownership of Common 
Stock on Schedule 13G under the Securities Exchange Act of 1934, as amended 
(the "Exchange Act"), or on Schedule 13D under the Exchange Act which 
Schedule 13D does not state any intention or reserve the right to, control or 
influence Ecolab or engage in certain other actions, so long as such person 
neither reports nor is required report such ownership other than as described 
in this proviso (the earliest such dates being called the "Distribution 
Date"). Notwithstanding the foregoing, (x) Henkel KGaA ("Henkel") shall not 
be an Acquiring Person if, so long as, it is a party to a written agreement 
with Ecolab which agreement imposes one or more limitations on the amount of 
Henkel's beneficial; ownership of Common Stock, and if, and so long as, such 
agreement continues be binding on Henkel and Henkel is in compliance with the 
terms of such agreement, and (y) Ecolab shall not declare Henkel to be an 
Adverse Person.

                  Until the Distribution Date (or earlier redemption or 
expiration of the Rights), (i) the Rights will be transferred with and only 
with the Common Stock (except in connection with the redemption of the 
Rights), (ii) new Common Stock certificates issued after the Rights Record 
Date upon transfer, replacement or new issuance of Common Stock will contain 
a notation incorporating the Rights Agreement by reference and (iii) the 
surrender for transfer of any certificates for Common Stock outstanding will 
also constitute the transfer of the Rights associated with the Common Stock 
represented by such certificate.

                                       23
<PAGE>

                  The Rights will become first exercisable on the 
Distribution Date and will expire at the close of business on March 11, 2006 
(the "Expiration Date"), unless earlier redeemed by Ecolab as described 
below. Notwithstanding the foregoing, the Rights will not be exercisable 
after the occurrence of a Triggering Event (as defined below) until Ecolab's 
right of redemption has expired.

                  As soon as practicable after the Distribution Date, 
separate certificates evidencing the Rights (the "Rights Certificates") will 
be mailed to holders of record of the Common Stock as of the close of 
business on the Distribution Date and, thereafter, such separate Rights 
Certificates alone will evidence the Rights. Except for shares of Common 
Stock issued or sold after the Distribution Date pursuant to the exercise of 
stock options or under any employee benefit plan or arrangement granted or 
awarded prior to the Distribution Date, or the exercise, conversion or 
exchange of securities issued by Ecolab, and except as otherwise determined 
by the Board of Directors of Ecolab, only shares of Common Stock issued prior 
to the Distribution Date will be issued with Rights.

                  In the event that any person shall become (a) an Acquiring 
Person (except (i) pursuant to an offer for all outstanding shares of Common 
Stock which the independent directors of Ecolab determine to be fair to and 
otherwise in the best interest of Ecolab and its stockholders after receiving 
advice from one or more investment banking firms (a "Qualifying Offer") and 
(ii) for certain persons who report their ownership on Schedule 13G under the 
Exchange Act or on Schedule 13D under the Exchange Act, provided that they do 
not state any intention to, or reserve the right to, control or influence 
Ecolab and such persons certify that they became an Acquiring Person 
inadvertently and they agree that they will not acquire any additional shares 
of Common Stock) or (b) an Adverse Person (either such event is referred to 
herein as a "Triggering Event"), then the Rights will "flip-in" and entitle 
each holder of a Right, except as provided below, to purchase, upon exercise 
at the then-current Purchase Price, that number of shares of Common Stock 
having a market value of two times such Purchase Price.

                  Any Rights beneficially owned at any time on or after the 
earlier of the Distribution Date and the Stock Acquisition Date by an 
Acquiring Person, an Adverse Person or an affiliate or associate of an 
Acquiring Person or an Adverse Person (whether or not such ownership is 
subsequently transferred) will become null and void upon the occurrence of a 
Triggering Event, and any holder of such Rights will have no right to 
exercise such Rights.

                  In the event that, following a Triggering Event, Ecolab is 
acquired in a merger or other business combination in which the Common Stock 
does not remain outstanding or is changed (other than a merger consummated 
pursuant to a Qualifying Offer) or 50% of the assets or earning power of 
Ecolab and its Subsidiaries (as defined in the Rights Agreement) (taken as a 
whole) is sold or otherwise transferred to any person (other than Ecolab or 
any Subsidiary of Ecolab) in one transaction or a series of related 
transactions, the Rights will "flip-over" and entitle each holder of a Right, 
except as provided in the preceding paragraph, to purchase, upon the exercise 
of the Right at the then-current Purchase Price, that number of shares of 
common stock of the acquiring company (or, in certain circumstances, one of 
its affiliates) which at the time of such transaction would have a market 
value of two times such Purchase Price.

                  The number of Rights associated with each share of Common 
Stock shall be proportionately adjusted after the Rights Record Date and 
prior to the Distribution Date (or earlier redemption or expiration of the 
Rights) for any (i) declaration of a dividend on the outstanding shares of 
Common Stock payable in shares of Common Stock, (ii) subdivision of the 
outstanding shares of Common Stock, or (iii) combination of the outstanding 
shares of Common Stock into a smaller number of shares, such that the number 
of Rights thereafter associated with each share of Common Stock following any 
such event shall equal the result obtained by multiplying the number of 
Rights associated with each share of Common Stock immediately prior to such 
event by a fraction, the numerator of which shall be the total number of 
shares of Common Stock outstanding immediately prior to the occurrence of the 
event and the denominator of which shall be the total number of shares of 
Common Stock outstanding immediately following the occurrence of such event. 
Upon distribution of the Stock Split, one-half (1/2) of a Right will be 
associated with each share of Common Stock.

                  In addition, the Purchase Price is subject to adjustment 
from time to time to prevent dilution upon the (i) declaration of a dividend 
on the Preferred Stock payable in shares of Preferred Stock, (ii) subdivision 
of the outstanding Preferred Stock, (iii) combination of the outstanding 
Preferred Stock into a smaller number of shares, (iv) issuance of any shares 
of Ecolab's capital stock in a reclassification of the Preferred Stock 
(including any such reclassification in connection with a consolidation or 
merger in which Ecolab is the continuing or surviving corporation), (v) grant 
to holders of the Preferred Stock of certain rights, options, or warrants to 
subscribe for Preferred Stock or securities convertible into Preferred Stock 
at less than the current market price of the Preferred Stock or 
(vi) distribution to holders of the Preferred Stock or other evidences of 
indebtedness, cash (other than a regular quarterly cash dividend payable out 
of the earnings or retained earnings of Ecolab), subscription rights, 
warrants, or assets (other than a dividend payable in Preferred Stock, but 
including any dividend payable in stock other than Preferred Stock).

                                       24
<PAGE>

                  With certain exceptions, no adjustment in the Purchase 
Price will be required until cumulative adjustments require an adjustment of 
at least 1% of the Purchase Price. At any time until the earlier of (i) 10 
days following the Stock Acquisition Date and (ii) the Expiration Date, 
Ecolab may redeem the Rights in whole, but not in part, at a price of $.01 
per Right. Ecolab may, at its option, pay the redemption price in cash, 
shares of Common Stock (based on the current market price of the Common Stock 
at the time of redemption) or any other form of consideration deemed 
appropriate by the Board of Directors of Ecolab. Immediately upon the action 
of Ecolab's Board of Directors ordering redemption of the Rights, the right 
to exercise the Rights will terminate and the only right of the holders of 
Rights will be to receive the applicable redemption price. In addition, after 
a Triggering Event, at the election of the Board of Directors of Ecolab, the 
outstanding Rights (other than those beneficially owned by an Acquiring 
Person, Adverse Person or an affiliate or associate of an Acquiring Person or 
Adverse Person) may be exchanged, in whole or in part, for shares of Common 
Stock, or shares of preferred stock of Ecolab having essentially the same 
value or economic rights as such shares. Immediately upon the action of the 
Board of Directors of Ecolab authorizing any such exchange, and without any 
further action or any notice, the Rights (other than Rights which are not 
subject to such exchange) will terminate and such Rights will only entitle 
holders to receive the shares issuable upon such exchange.

                  Until a Right is exercised, the holder thereof, as such, 
will have no rights as a stockholder of Ecolab, including, without 
limitation, the right to vote or to receive dividends. While the distribution 
of the Rights will not be taxable to stockholders or to Ecolab, stockholders 
may, depending upon the circumstances, recognize taxable income in the event 
that the Rights become exercisable for Common Stock (or other consideration) 
of Ecolab or for common stock of the acquiring company as set forth above.

                  At any time prior to the Distribution Date, Ecolab may, 
without the approval of any holder of the Rights, supplement or amend any 
provision of the Rights Agreement. Thereafter, the Rights Agreement may be 
amended only (i) to cure ambiguities, (ii) to correct inconsistent 
provisions, (iii) to shorten or lengthen any time period thereunder or (iv) 
in ways that do not adversely affect the Rights holders (other than an 
Acquiring Person or Adverse Person). From and after the Distribution Date, 
the Rights Agreement may not be amended to lengthen (A) a time period 
relating to when the Rights may be redeemed at such time as the Rights are 
not then redeemable, or (B) any other time period unless such lengthening is 
for the purpose of protecting, enhancing or clarifying the rights of, and/or 
the benefits to, the holders of Rights (other than an Acquiring Person or 
Adverse Person.)

                  The Rights have certain anti-takeover effects. The Rights 
will cause substantial dilution to a person or group that attempts to acquire 
Ecolab on terms not approved by Ecolab's Board of Directors. The Rights 
should not interfere with any merger or other business combination approved 
by the Board of Directors of Ecolab since the Board of Directors may, at its 
option, at any time until ten days following the Stock Acquisition Date, 
redeem all, but no less than all, of the then outstanding Rights at the 
applicable redemption price.

                  GCS does not have a similar stock purchase rights plan in 
place.

VOTING RIGHTS; PREEMPTIVE RIGHTS; CUMULATIVE VOTING; SPECIAL VOTING PROVISIONS

                  The holders of both Ecolab Common Stock and GCS Common 
Stock are entitled to one vote per share with respect to all matters 
submitted to a vote of the Ecolab and GCS stockholders, respectively. Neither 
the Ecolab stockholders nor the GCS stockholders have preemptive rights with 
respect to unissued shares of capital stock. Moreover, cumulative voting is 
not authorized under either the Ecolab Restated Certificate of Incorporation 
or GCS Certificate of Incorporation.
   
                  Article IV of the Ecolab Restated Certificate of 
Incorporation requires the approval of at least 80% of the outstanding shares 
of Ecolab Common Stock entitled to vote if a transaction involves a Business 
Combination (as hereinafter defined) with, or proposed by or on behalf of, 
any Interested Stockholder (as hereinafter defined) or any Affiliate or 
Associate (as hereinafter defined) of any Interested Stockholder or any 
person who thereafter would be an Affiliate or Associate of such Interested 
Stockholder, unless certain fair price criteria and procedural requirements 
are satisfied or the transaction is approved by a majority of Continuing 
Directors (as hereinafter defined).
    
                  An "Interested Stockholder" is any person who (a) is the 
beneficial owner, directly or indirectly, of more than ten percent (10%) of 
the voting power of the outstanding Voting Stock; or (b) is an Affiliate of 
Ecolab and at any time within the two-year period immediately prior to the 
date in question was the beneficial owner, directly or indirectly, of ten 
percent (10%) or more of the voting power of the then outstanding voting 
stock; or (c) is an assignee of or has otherwise succeeded to any shares of 
voting stock which were at any time within the two-year period immediately 
prior to the date in question beneficially owned by an Interested 
Stockholder, if such assignment or succession shall have occurred in the 
course of a transaction or series of transactions not involving a public 
offering within the meaning of the Securities Act of 1933. A "Business 
Combination" includes certain transactions with or proposed by or on behalf 
of an Interested Stockholder or related parties, including, among others, 
(i) a merger or consolidation of

                                       25
<PAGE>

Ecolab or any subsidiary; (ii) the sale or disposition by Ecolab or any 
subsidiary of any assets or securities having an aggregate fair market value 
of $10 million or more; (iii) the adoption of any plan or proposal for the 
liquidation or dissolution of Ecolab proposed by or on behalf of an 
Interested Stockholder or any Affiliate of any Interested Stockholder; or 
(iv) any reclassification of securities, recapitalization, merger or other 
transaction with the effect, directly or indirectly, of increasing an 
Interested Stockholder's proportionate share of the outstanding capital stock 
of Ecolab or a subsidiary. A "Continuing Director" is a member of the Board 
of Directors who is unaffiliated with an Interested Stockholder or was a 
director before any Interested Stockholder became an Interested Stockholder 
and any successor of a Continuing Director, while such successor is a member 
of the Board, who is unaffiliated with the Interested Stockholder and is 
recommended or elected to succeed by a majority of Continuing Directors.
   

                  The Business Combination provisions of the Ecolab Restated 
Certificate of Incorporation are intended to prevent certain of the potential 
inequities of Business Combinations that are part of "two-step" transactions. 
In the absence of such provisions, a purchaser who acquired control of Ecolab 
could subsequently, by virtue of such control, force the remaining 
stockholders to sell or exchange their shares at a price that would not 
reflect any premium such purchaser may have paid in order to acquire its 
controlling interest. Such provisions may also discourage the accumulation of 
large blocks of Ecolab's stock which could be disruptive to the stability of 
Ecolab's important relationships with its employees, customers and the 
communities that it serves. Such an accumulation could precipitate a change 
of control of Ecolab on terms unfavorable to Ecolab's other stockholders.

                  The Business Combination provisions of the Ecolab Restated 
Certificate of Incorporation may render more difficult or discourage a merger 
with or takeover of Ecolab, the acquisition of control of Ecolab by a large 
stockholder and the removal of incumbent management. Such provisions would 
also discourage some takeover attempts by persons who intend to acquire 
Ecolab in two steps and eliminate remaining stockholder interests by means of 
a Business Combination involving less consideration per share than the 
acquiring person would propose to pay for its initial interest in Ecolab 
equal to or greater than 10% (but less than 100%) of the outstanding voting 
stock of Ecolab. To the extent that this provision discourages certain 
business combinations, Ecolab's stockholders may be deprived of higher market 
prices for their stock that often prevail as a result of such events.
    
                  Pursuant to an agreement between Ecolab and Henkel (the 
"Stockholders Agreement"), Henkel has agreed to vote its shares, in the case 
of election of directors of the Company (as described below) or certain 
stockholder proposals, in accordance with the recommendation or directions of 
the Ecolab 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 Ecolab Board or pro rata in the 
same manner and proportion that votes of the stockholders of Ecolab (other 
than Henkel and officers or directors of Ecolab) have been cast. Any vote 
with respect to "strategic transactions" (among other things, an increase in 
the authorized shares or an amendment to the Ecolab Restated Certificate of 
Incorporation, as well as a disposition, recapitalization or dissolution of 
Ecolab or other transactions which could have a material adverse effect upon 
Henkel's investment in the Ecolab Common Stock) may be cast at Henkel's sole 
discretion.

BOARD OF DIRECTORS

                  The Ecolab Board is divided into three classes and 
currently consists of thirteen directors who serve for three-year terms. The 
number of directors on the Ecolab Board is subject to change by action of the 
Ecolab Board in its discretion. Pursuant to the Stockholders Agreement, a 24% 
stockholder of Ecolab, Henkel is entitled to designate nominees for election 
to the Company's Board of Directors proportionate to its holding. Currently, 
Henkel has designated three of Ecolab's thirteen directors. The GCS Board is 
not classified and consists of four directors who serve for one year terms. 
The number of directors on the GCS Board is subject to change by action of 
the GCS Board but cannot be less than four.

REMOVAL OF DIRECTORS

                  Under the Ecolab Restated Certificate of Incorporation and 
Bylaws, any director may be removed from office, but only for cause, and only 
upon the affirmative vote of the holders of a majority of the shares entitled 
to vote thereon. Under the GCS Bylaws, any director may be removed at any 
time, with or without cause, by the holders of a majority or the shares 
entitled to vote thereon.

NEWLY-CREATED DIRECTORSHIPS AND VACANCIES

                  Under the Ecolab Bylaws and Restated Certificate of 
Incorporation and the GCS Bylaws, any vacancy occurring on the board may be 
filled by the affirmative vote of a majority of the remaining directors 
though less than a quorum. Under the Ecolab Bylaws, newly-created 
directorships are required to be filled by the affirmative vote of a majority 
of the directors though less than a quorum. Under the GCS Bylaws, 
newly-created directorships may be filled by the vote of a majority of either 
the GCS Board or the GCS stockholders, depending upon whether such election 
takes place at a meeting of the GCS Board or the GCS stockholders.

NOMINATION OF DIRECTORS

                  Ecolab directors may be nominated by the Board of Directors 
or a Committee appointed by the Board of directors. Ecolab Bylaws allow 
stockholders to submit a nominee for election to the Board of Directors at an 
Annual Meeting only if such nomination is submitted in writing and contains 
certain information pertaining to the stockholder nominator and the director 
nominee as specified in the Bylaws and such proposal is received by Ecolab 
not less than 90, nor more than 135, days prior to the one-year

                                       26
<PAGE>

anniversary date of the preceding Annual Meeting. The GCS directors may be 
nominated by the board of directors or a committee appointed by the board of 
directors or by any stockholder entitled to vote in the election of directors 
generally.

STOCKHOLDER PROPOSALS

                  Ecolab stockholders may have proposals considered at an 
annual meeting in accordance with the Ecolab Bylaws, the DGCL and the Federal 
securities laws. The Ecolab Bylaws allow Stockholders to submit a proposal 
for consideration at its annual meeting only if such proposal is a proper one 
for consideration by stockholders, is in writing containing certain 
information specified in the Bylaws pertaining to the proponent and the 
proposal and is received by Ecolab not less than 90, nor more than 135, days 
prior to the one year anniversary date of the preceding annual meeting. GCS 
stockholders may have proposals considered at an annual meeting in accordance 
with the DGCL.

SPECIAL MEETINGS OF THE STOCKHOLDERS

                  Under the Ecolab Bylaws, a special meeting of the 
stockholders may be called by either the Ecolab Board or the chairman of the 
Ecolab Board and must be called upon written request by the holders of 80% of 
the outstanding Ecolab Common Stock. Under the GCS Bylaws, a special meeting 
of the stockholders may be called by the President or the GCS Board and must 
be called upon the request of holders of 25% or more of the outstanding GCS 
Common Stock.

STOCKHOLDER ACTION BY WRITTEN CONSENT

                  Under both the Ecolab Bylaws and the GCS Bylaws, any action 
that may be taken at a meeting of Ecolab's or GCS' stockholders may be taken 
without a meeting of stockholders if a written consent setting forth the 
action to be taken is signed by the holders of not less than the minimum 
number of votes that would be necessary to take such action at a meeting of 
stockholders.

LIMITATION ON DIRECTOR'S LIABILITY

                  The Ecolab Restated Certificate of Incorporation provides 
for a limitation of director liability to Ecolab or its stockholders to the 
fullest extent permitted by the DGCL. The DGCL permits a corporation to 
provide in its certificate of incorporation that a director shall not be 
personally liable for monetary damages stemming from breaches of fiduciary 
duties. Under the DGCL, a charter provision limiting directorial liability 
cannot relieve a director of personal liability for (i) any breach of the 
director's duty of loyalty to the corporation or its stockholders; (ii) acts 
or omissions not in good faith or which involve intentional misconduct or a 
knowing violation of law; (iii) unlawful payment of dividends or unlawful 
repurchases of stock or; (iv) any transactions from which the director 
derived an improper personal benefit.

                  The GCS Certificate of Incorporation provides that no 
director of the corporation shall be liable to GCS or its stockholders for 
monetary damages for breach of fiduciary duty except for breaches of the duty 
of loyalty, acts or omissions not in good faith or involving intentional 
misconduct or knowing violations of law, any violation of Section 174 of the 
DGCL or any transactions from which an improper personal benefit was derived.

INDEMNIFICATION

                  The Ecolab Bylaws provide that Ecolab will indemnify, to 
the fullest extent permissible under the DGCL, any person who is a party to, 
or is threatened to be made a party to, any action, suit or proceeding 
(whether civil, criminal, administrative, investigative or other) by reason 
of the fact that he or she is or was a director or officer of Ecolab or while 
a director or officer of Ecolab is or was serving at the request of Ecolab as 
a director, officer, employee or agent of another corporation, as its 
representative in another enterprise against all costs reasonably incurred or 
suffered by such person. Furthermore, Ecolab has directors and officers 
liability insurance which protects each director or officer from certain 
claims and suits, including stockholder derivative suits, even where the 
director may be determined to not be entitled to indemnification under the 
DGCL and claims and suits arising under the Securities Act. The policy may 
also afford coverage under circumstances where the facts do not justify a 
finding that the director or officer acted in good faith and in a manner that 
was in or not opposed to the best interests of Ecolab.

                  Ecolab has entered into indemnification agreements with 
each of its directors (the "Indemnification Agreements"). The Indemnification 
Agreements provide for the prompt indemnification "to the fullest extent 
permitted by law" and for the prompt advancement of expenses, including 
attorneys' fees and other costs, expenses and obligations paid or incurred in 
connection with investigating, defending, being a witness or participating in 
(including on appeal) any threatened, pending or completed action, suit

                                       27
<PAGE>

or proceeding related to the fact that such director is or was a director, 
officer, employee, trustee, agent or fiduciary of Ecolab or is or was serving 
at the request of Ecolab as a director, officer, employee, trustee, agent or 
fiduciary of another corporation, partnership, joint venture, employee 
benefit plan trust or other enterprise, or by reason of anything done or not 
done by a director in any such capacity. The Indemnification Agreements 
further provide that Ecolab has the burden of proving that a director is not 
entitled to indemnification in any particular case.


   

                  The GCS Certificate of Incorporation and the GCS Bylaws 
provide that GCS will indemnify, to the fullest extent permissible under the 
DGCL, any person who is a party to, or is threatened to be made a party to, 
any action, suit, or proceeding (whether civil, criminal, administrative, 
investigative or other) by reason of the fact that he or she is or was a 
director or officer of GCS or while a director or officer of GCS is or was 
serving at the request of GCS as a director, officer, employer or agent of 
another corporation or as its representative in another enterprise against 
all costs reasonably incurred or suffered by such person.

    
                               DESCRIPTION OF GCS

GENERAL

                  GCS was incorporated in California as Gas Consumers 
Service, Inc. in 1926. Its name was changed to GCS Service, Inc. in 1978 and 
was redomesticated to Delaware in 1991. Its headquarters are located at 100 
Mill Plain Road, Danbury, CT 06811. Its telephone number is (203)792-4599.

                  In 1996, the company merged with its parent Tyfam, Inc. 
(Tyfam) in order to streamline its corporate structure. GCS was the surviving 
corporation. Tyfam owned 83.2% of GCS which was distributed proportionately 
to the stockholders of Tyfam. GCS owned certain shares of Tyfam stock which 
had a carrying value at September 30, 1995 of $3,438,935 and was recorded as 
a reduction to retained earnings.

   
                  In 1995, GCS entered into an agreement to repurchase all of 
GCS stock and Tyfam stock held by Barton P. Tyler (the former chief executive 
officer of GCS). The negotiated cost to GCS of the stock repurchase was 
$3,786,480, $846,183 of which was allocated to Barton Tyler's common stock 
holdings in GCS and was recorded as part of GCS's treasury stock, and 
$2,940,297 was allocated to his common stock ownership in Tyfam, Inc. and was 
reflected as an investment in GCS's parent at September 30, 1995. The stock 
purchase agreement required the Company to make a $150,000 initial payment 
followed by monthly payments of $55,181 (which includes principal and 
interest) for a period of eight years commencing on June 1, 1995.
    
                  In 1995, GCS entered into a $4,550,000 revolving line of 
credit and term loan with Bank of New York. The loan facility is secured by 
the GCS's inventory and accounts receivable. The loan agreement requires GCS 
to maintain certain minimum working capital, tangible net worth and debt 
ratios. It also restricts new borrowings, payment of dividends and redemption 
and issuances of capital stock in excess of $150,000 per year. Borrowings 
under this line of credit are based on eligible accounts receivable and 
inventory and are guaranteed by the principal stockholder of the GCS.

BUSINESS

                  GCS believes it is the largest independent commercial food 
preparation, refrigeration and warewashing service company in the United 
States. GCS operates through 28 branches located in major metropolitan areas. 
Each branch also operates a parts department which sells replacement parts 
for commercial cooking, refrigeration and dishwashing equipment.

</TABLE>

         GCS's primary customers are manufacturers of commercial cooking, 
refrigeration and dishwashing equipment and their customers: commercial food 
service operators, including quick service restaurants, full service 
restaurants, hotels, universities and nursing homes.

         Parts and supplies needed by GCS to conduct its business are widely 
available through various channels of distribution. Most parts are purchased 
from the original equipment manufacturers whose products are serviced by the 
GCS.

                                       28
<PAGE>

         GCS's inventory consists primarily of replacement parts for 
commercial cooking, refrigeration and dishwashing equipment. In order to 
provide quick service and to fulfill contractual obligations to equipment 
manufacturers, a large percentage of the company's inventory is stored on 
GCS's service vehicles with the balance stored at the local branch office. 
Generally, GCS does not warehouse inventory in centralized locations.

         Substantially all of the vehicles in use by GCS are leased.

         Inventory and accounts receivable are the GSC' primary assets.

         GCS extends short term credit to most of its customers who are 
billed after the completion of each service call and generally given thirty 
(30) days to pay.

CUSTOMERS AND COMPETITION

         GCS' largest customers are Welbilt, a subsidiary of Berisford 
(BRFD-LSE), Middleby Marshall (MBY) and Premark (PMI). Each of these 
companies manufacture cooking, refrigeration and dishwashing equipment and 
contract with the Company for repair services and parts distribution.

         GCS believes there is more demand for food equipment service than 
there are companies providing that service. As a result, the principal method 
of competition in the industry is performance relative to customer 
expectations. GCS is the largest servicer, unaffiliated with a manufacturer 
of food equipment, in the U.S. It has a strong reputation for fast, quality 
customer service.

         GCS provides service within a fifty (50) mile radius of the 
following metropolitan areas:

In each of these areas GCS competes with multiple smaller competitors, none 
of whom operate in more than three of the same areas that GCS operates in. 
Food equipment manufacturers who provide their own service with company 
personnel compete with GCS in many or all of these markets; however, the 
brands and types of equipment serviced are significantly different.

EMPLOYEES

         GCS has 383 employees. The largest segment of the Company's 
workforce are field service technicians, including many certified by the 
Environmental Protection Agency to reclaim and recycle refrigerants. GCS 
believes it is in compliance with all material, federal, state and local 
licensing requirements, labor law and environmental laws as they apply to its 
work force and industry. In March 1998, the Company's Chief Financial Officer 
was terminated. At that time the shares of GCS Common Stock and Company 
Options owned by him were repurchased pursuant to a pre-existing agreement.

PROPERTIES

GCS owns a facility in Philadelphia, Pennsylvania consisting of 10,000 s.f. 
of combined office and warehouse space.

effect on the Company's results of operations and financial condition.



           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS

OVERVIEW
   
         GCS is a third-party field service company operating a network of 
branch offices throughout the United States. The primary business conducted 
by each branch office is the repair and servicing of commercial cooking, 
refrigeration and warewashing equipment, usually on each customer's premises. 
In addition, each office operates a parts department which sells parts for 
commercial cooking, refrigeration and warewashing equipment to others.
    
         The primary customers of the Company are manufacturers of commercial 
cooking, refrigeration and warewashing equipment and their customers and 
commercial food service operators, including quick service restaurants, full 
service restaurants, hotels, universities and nursing homes.

         The largest segment of the Company's workforce is comprised of field 
service technicians, including many certified by the Environmental Protection 
Agency to reclaim and recycle refrigerants. The Company believes it is in 
compliance with federal, state and local licensing requirements, labor law 
and environmental laws as they apply to its work force and industry.

         Inventory and accounts receivable are the Company's significant 
assets. The Company's inventory consists of replacement parts for commercial 
cooking, refrigeration and warewashing equipment. In order to provide timely 
repairs, and to fulfill contractual obligations to equipment manufacturers, a 
large percentage of the inventory is maintained on Company leased trucks, 
driven by the service technicians, with the remainder held at the Company's 
branch offices so that they are available locally. Generally the Company does 
not centralize inventory. Substantially all vehicles in use by the Company 
are leased.

         The Company extends short term credit to most of its customers.

SIX MONTHS ENDED MARCH 31, 1998
COMPARED TO SIX MONTHS ENDED MARCH 31, 1997

         Results discussed in this section have not been audited, except as 
part of the audit of the full fiscal year ended September 30, 1997.

         Sales for the six months ended March 31, 1998 were $24,928,591, 7.3% 
above the same period sales of the prior fiscal year. The increase was 
primarily due to volume increases at several branches. Sales for the 
remainder of fiscal 1998 are expected to level off.

         Gross profit as a percent of sales was 33.7% for the six months 
ended March 31, 1998 compared to 34.5% for the same period in the prior 
fiscal year. The decrease in the gross margin from period to period is 
reflective of inflationary increases in servicemen and contract labor 
salaries as well as material cost, partially offset by inflationary sale price 
increases to the Company's customers.

         Selling, general and administrative expenses were up 16.0% compared to
the same period a year ago. The increased costs were required to support the 
increase in sales for the six months ended March 31, 1998. As a percent of 
sales, selling, general and administrative expenses were 2.3% higher for the 
six-month period ended March 31, 1998 as compared to the same period in the 
prior year primarily as a result of the receipt of a rebate for workers' 
compensation insurance premiums during the six months ended March 31, 1997, 
due to favorable claims experience.


                                       30
<PAGE>

         Interest expense incurred by the Company was $238,808 and $262,708 
for the six months ended March 31, 1998 and March 31, 1997, respectively. The 
decrease for the six-month period ended March 31, 1998 is reflective of lower 
debt levels as compared to the six months ended March 31, 1997.

         Income from operations for the six months ended March 31, 1998 of 
$879,466 was 42.8% lower than the same period a year ago relecting the lower 
gross margin performance and the rebate of the insurance premiums previously 
discussed above. 

         The effective tax rate for the six months ended March 31, 1998 was 
42.0%, compared to 43.8% for the six months ended March 31, 1997. The higher 
effective rate in 1997 was the result of conservative provisioning during 
that period. 

FISCAL YEAR ENDED SEPTEMBER 30, 1997
COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30, 1996

         Sales for fiscal year 1997 were $48,128,363, an increase of 10.6% 
from fiscal year 1996. The increase was primarily driven by higher service 
sales of approximately $3,700,000 due to the upgrade of over 1,000 conveyor 
ovens by a national quick service restaurant chain which the Company provided 
service for in 1997.

         Gross profit as a percent of sales was 35.4% for fiscal year 1997 
versus 36.1% for fiscal year 1996. The decrease is primarily a result of 
higher indirect costs attributable to service truck maintenance and 
depreciation expenses.

         Selling, general and administrative expenses were up slightly less 
than 1% from the prior year, but down 2.7% as a percent of sales reflective 
of a gain recognized in 1997 on the sale property in Cambridge, Massachusetts 
and the effect of cost reductions at the Company's corporate headquarters. 

         Interest expense incurred by the Company of $492,484 and $511,983 
for fiscal year 1997 and fiscal year 1996, respectively, primarily related to 
a note payable to a former officer and the Company's revolving line of credit.

         The effective tax rate for fiscal year 1997 was 45.3%, compared to 
44.6% for fiscal year 1996. The higher effective rate in 1997 was the result 
of conservative provisioning during the year.

FISCAL YEAR ENDED SEPTEMBER 30, 1996
COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30, 1995

         Sales for fiscal year 1996 were $43,533,930, an increase of 
$2,394,995 or 5.8% from fiscal year 1995. The increase was primarily driven 
by higher service and direct sale merchandise business, but was negatively 
impacted by the closing of the Company's Indianapolis, Indiana branch office 
effective September 30, 1995. The Indianapolis branch had sales during the 
fiscal year ended September 30, 1995 of approximately $1,056,000.

         Gross profits as a percent of sales was 36.1% for fiscal year 1996 
versus 35.4% for fiscal year 1995. The slight increase is primarily a result 
of reduced direct labor fringe benefit costs inclusive of a reduction in 
workers' compensation costs due to favorable claims experience.

         Selling, general and administrative expenses were 30.7% of sales in 
fiscal year 1996 versus 31.8% of sales in fiscal year 1995. During 1996, the 
Company experienced a significant reduction in bad debt expenses as a result 
of improved credit and collections which caused the decrease as a percent of 
sales from 1995 to 1996.

         Interest expense incurred by the Company was $511,983 and $131,402 
for fiscal year 1996 and fiscal year 1995, respectively. The increase in 
interest expense was due to the repurchase of the Company's stock from a 
former officer of the Company which was financed with the former officer 
beginning June 1, 1995, and increased borrowings under the Company's 
revolving line of credit during fiscal year 1996.

         The effective tax rate for fiscal year 1996 was 44.6%, compared to 
41.3% for fiscal year 1995. The higher effective rate in fiscal year 1996 
included an adjustment for state deferred taxes.

FINANCIAL CONDITION

CASH FLOWS FROM OPERATING ACTIVITIES

         Over the last three and a half years (inclusive of the six month 
period ended March 31, 1998) cash flows from operating activities were 
$2,545,981. These funds were used primarily for the payment of capital 
expenditures, working capital and debt service.

SIX MONTHS ENDED MARCH 31, 1998 VERSUS
SIX MONTHS ENDED MARCH 31, 1997

         Cash flows from operating activities were $86,397 for the six months 
ended March 31, 1998 compared to $(11,973) for the six months ended March 31, 
1997. The fluctuation from period to period is reflective of lower net income 
for the period ended March 31, 1998 offset by variability in the management 
of working capital.

FISCAL YEAR ENDED SEPTEMBER 30, 1997 VERSUS
FISCAL YEAR ENDED SEPTEMBER 30, 1996

         Cash flows from operating activities for fiscal year 1997 were 
$1,317,776 compared to $202,991 for fiscal year 1996. The increase over 1996 
was primarily due to an increase in net income, the timing of taxes payable 
and reduced inventory purchases in fiscal year 1997. During fiscal year 1997, 
cash flows from operations was principally used to fund capital expenditures 
and working capital.

FISCAL YEAR ENDED SEPTEMBER 30, 1996 VERSUS
FISCAL YEAR ENDED SEPTEMBER 30, 1995

         Cash flows from operating activities for fiscal year 1996 were 
$202,991 compared to $938,817 for fiscal year 1995. The decrease from fiscal 
year 1995 is mainly attributable to higher inventory balances during fiscal 
year 1996 which accounted for a net cash outflow of $1,238,558. During fiscal 
year 1996, cash flows from operations was principally used to fund capital 
expenditures, debt service and working capital.

LIQUIDITY AND CAPITAL RESOURCES
   
         In June of 1995, the Company utilized an opportunity to repurchase 
all of the stock of the Company held by the former chief executive officer 
and Tyfam, Inc. The agreement entered into resulted in a negotiated cost of 
the repurchase of $3,786,480. The stock purchase agreement required the 
Company to make a $150,000 initial payment followed by monthly payments of 
$55,181 for a period of eight years. Since then, the Company has continued to 
utilize the availability of its revolving line of credit totaling $4,550,000 
at March 31, 1998, of which $1,918,660 was available as of that date.
    
         Cash flows from operations and the ability to borrow from a variety 
of sources should provide the Company with the liquidity to continue the 
investments necessary to meet the Company's long-term strategic goals.

YEAR 2000

         The Company recognizes the need to ensure its operations will not be 
adversely impacted by Year 2000 software failures. Software failures due to 
processing errors potentially arising from calculations using the Year 2000 
date are a known risk. The Company has addressed this risk to the 
availability and integrity of financial systems and the reliability of 
operational systems. The Company had previously decided to upgrade its 
computer systems. The Company believes that these upgrades may allow it to 
achieve Year 2000 compliance. The cost of these upgrades, which are currently 
in progress and expected to be completed during 1999, are not material to the 
Company's result of operations or financial position. Remaining expenditures 
are expected to be less than $200,000. Based on current information, the 
Company believes that no significant additional expenditures may be required 
to specifically achieve Year 2000 compliance.

         Certain matters discussed herein are forward-looking statements that 
involve risks and uncertainties. Such forward-looking statements may be 
identified by the use of terminology such as "may," "will," "expect," 
"anticipate," "intend," "designed," "estimate," "should," or "continue" or 
the negatives thereof or other variations or comparable terms. These 
forward-looking statements involve certain risks and uncertainties and other 
factors which may cause actual results, performance or achievements of the 
company, or industry results, to differ materially from those contemplated or 
projected, forecast, estimated or budgeted or implied in such forward-looking 
statements including, among others, the following possibilities: (i) 
heightened competition, including specifically the intensification of price 
competition, the entry of new competitors and the formation of new products 
by new and existing competitors; (ii) adverse state and federal legislation 
and regulation; (iii) failure to obtain new customers or retain existing 
customers; (iv) inability to carry out marketing and/or expansion plans; (v) 
loss of key executives; (vi) changes in interest rates; (vii) general 
economic and business conditions which are less favorable than expected and 
(viii) unanticipated changes in industry trends. In addition, factors that 
could cause actual results of GCS (assuming consummation of the merger) to 
differ materially from those contemplated by or projected, forecast, 
estimated or budgeted in forward-looking statements relating to the results 
of operations and business of GCS following the merger, including (a) cost 
savings that will be realized from the merger (see "THE MERGER -Reasons for 
the Merger; Recommendation of the Board") and (b) costs associated with the 
merger, including, among others, the following possibilities: (i) the 
expected cost savings to be realized through combining certain functions of 
both Ecolab and GCS cannot be fully realized because the changes are not made 
or unanticipated offsetting costs are incurred and (ii) costs or difficulties 
related to the integration of the businesses of Ecolab and GCS are greater 
than expected.

INDEPENDENT AUDITORS' REPORT


The Board of Directors and Stockholders
GCS Service, Inc.:

We have audited the accompanying balance sheets of GCS Service, Inc. as of
September 30, 1997 and 1996, and the related statements of income, stockholders'
equity and cash flows for the years then ended. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of GCS Service, Inc. as of
September 30, 1997 and 1996 and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

                          Notes to Financial Statements

                           September 30, 1997 and 1996

1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       a.     DESCRIPTION OF BUSINESS

              GCS Service, Inc. (the Company) services, repairs and sells parts
              for commercial cooking and refrigeration equipment, primarily to
              restaurants and institutional kitchens.

              During 1996, the Company completed a merger with its parent
              company, Tyfam, Inc. (Tyfam). As a result of the transaction,
              Tyfam merged with and into the Company with the Company remaining
              as the surviving corporation. Tyfam's ownership in the Company
              which was 83.2% prior to the transaction, was distributed
              proportionately to stockholders of the Company based upon those
              stockholders' direct ownership of Tyfam. The interest in Tyfam
              previously owned by the Company, with a carrying value at
              September 30, 1995 of $3,438,935, was recorded as a reduction to
              retained earnings.

              Upon completion of this transaction, there was no change in the
              Company's ownership percentages.

       b.     INVENTORY

              Inventory consists of replacement parts for gas, electric and
              steam operated cooking equipment and refrigeration equipment.
              Inventories are stated at cost or market, whichever is lower. Cost
              is determined using the first-in, first-out method for all
              inventories.

       c.     PROPERTY, EQUIPMENT AND DEPRECIATION

              Property and equipment are stated at cost. Plant and equipment
              under capital leases are stated at the present value of minimum
              lease payments at the inception of the lease.

              Depreciation on plant and equipment is calculated using the
              straight-line method over the estimated useful lives of the
              assets. Equipment held under capital leases and leasehold
              improvements are amortized straight-line over the shorter of the
              lease term or estimated useful life of the asset.

                    Notes to Financial Statements, Continued


       d.     INCOME TAXES

              The Company accounts for income taxes in accordance with Statement
              of Financial Account ing Standards No. 109 "Accounting for Income
              Taxes." Under this method, deferred income taxes
              are recognized for the tax consequences of "temporary differences"
              by applying enacted statutory tax rates to differences between the
              financial statement carrying amounts and the tax bases of existing
              assets and liabilities.

              Deferred income taxes have been provided for temporary differences
              primarily attributable to reporting of depreciation, inventory
              reserves, the allowance for doubtful accounts, deferred
              compensation, self-insurance reserves, and certain liabilities
              differently for tax as compared to financial reporting.

              Valuation allowances are established, when necessary, to reduce
              deferred tax assets to amounts that are more likely than not to be
              realized.

       e.     IMPAIRMENT OF LONG-LIVED ASSETS

              The Company adopted Statement of Financial Accounting Standards
              (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
              Assets and for Long-Lived Assets to be Disposed Of" as of October
              1, 1996, which had no material effect on the financial statements.
              The Company utilizes the undiscounted cash flow method to
              determine impairment in the carrying value of its long-lived
              assets. Measurement of an impairment loss is determined by
              reducing the carrying value of assets to fair value. Assets to be
              disposed of by sale or abandonment, as part of a plan committed to
              and approved by management, are recorded at the lower of the
              carrying value or the fair value less the cost to sell.

       f.     USE OF ESTIMATES

              The preparation of financial statements in conformity with
              generally accepted accounting principles requires management to
              make estimates and assumptions that affect the reported amounts of
              assets and liabilities at the date of the financial statements and
              the reported amounts of revenues and expenses during the reporting
              period. Actual results could differ from those estimates.

       g.     RECLASSIFICATIONS

              Certain prior year balances have been reclassified to conform to
              the 1997 presentation.

       Such violation was subsequently waived by the lender.

       and September 30, 1997, respectively under this credit facility which
       also reflects an outstanding stand-by letter of credit of $10,000.

       Certain other borrowings are collateralized by the Company's inventory
       and receivables.

       At September 30, 1997, the future aggregate annual principal payments of
       long-term debt are as follows:

       In assessing the realizability of deferred tax assets, management
       considered whether it is more likely than not that some portion or all of
       the deferred tax assets will not be realized. The ultimate realization of
       deferred tax assets is dependent upon the generation of future taxable
       income during the periods in which those temporary differences become
       deductible and opportunities for carrybacks. Management considered the
       scheduled reversal of deferred tax liabilities, projected future taxable
       income, carryback opportunities and tax planning strategies in making
       this assess ment. Based upon the results of operations of the current
       period and projections for future taxable income over the periods which
       the deferred tax assets are deductible, management believes it is more
       likely than not the Company will realize the benefits of these temporary
       deductible differ ences.

       effective income tax rate follows:

The Board of Directors and Stockholders
GCS Service, Inc.:

We have audited the accompanying balance sheets of GCS Service, Inc. as of 
September 30, 1996 and 1995, and the related statements of income, 
stockholders' equity and cash flows for the years then ended. These financial 
statements are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these financial statements based 
on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of GCS Service, Inc. as of 
September 30, 1996 and 1995 and the results of its operations and its cash 
flows for the years then ended in conformity with generally accepted 
accounting principles.

                          Notes to Financial Statements

                           September 30, 1996 and 1995

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     a.   DESCRIPTION OF BUSINESS

          GCS Service, Inc. (the Company) services, repairs and sells parts
          for commercial cooking and refrigeration equipment, primarily to
          restaurants and institutional kitchens.

          During 1996, the Company completed a merger with its parent 
          company, Tyfam, Inc. (Tyfam). As a result of the transaction, Tyfam 
          merged with and into the Company with the Company remaining as the 
          surviving corporation. Tyfam's ownership in the Company which was 
          83.2% prior to the transaction, was distributed proportionately to 
          stockholders of the Company's stock based upon those stockholders' 
          direct ownership of Tyfam. The interest in Tyfam previously owned 
          by the Company, with a carrying value at September 30, 1995 of 
          $3,438,935, was recorded as a reduction to retained earnings.

          Upon completion of this transaction, there was no change in the 
          Company's ownership percentages.

     b.   INVENTORY

          Inventory consists of replacement parts for gas, electric and steam 
          operated cooking equipment and refrigeration equipment. Inventories 
          are stated at cost or market, whichever is lower. Cost is 
          determined using the first-in, first-out method for all inventories.

     c.   PROPERTY, EQUIPMENT AND DEPRECIATION

          Property and equipment are stated at cost. Plant and equipment 
          under capital leases are stated at the present value of minimum 
          lease payments at the inception of the lease.

          Depreciation on plant and equipment is calculated using the 
          straight-line method over the estimated useful lives of the assets. 
          Equipment held under capital leases and leasehold improvements are 
          amortized straight-line over the shorter of the lease term or 
          estimated useful life of the asset.

     d.   INCOME TAXES

          The Company accounts for income taxes in accordance with Statement 
          of Financial Accounting Standards No. 109 "Accounting for Income 
          Taxes" (Statement 109). Under this method, deferred income taxes 
          are recognized for the tax consequences of "temporary differences" 
          by applying enacted statutory tax rates to differences between the 
          financial statement carrying amounts and the tax bases of existing 
          assets and liabilities. 


          Deferred income taxes have been provided for temporary differences 
          primarily attributable to reporting of depreciation, inventory 
          reserves, the allowance for doubtful

          accounts, deferred compensation, self-insurance reserves, and 
          certain liabilities differently for tax as compared to financial 
          reporting.

          Valuation allowances are established. when necessary, to reduce 
          deferred tax assets to amounts that are more likely than not to be 
          realized.

     e.   USE OF ESTIMATES

          The preparation of financial statements in conformity with 
          generally accepted accounting principles requires management to 
          make estimates and assumptions that affect the reported amounts of 
          assets and liabilities at the date of the financial statements and 
          the reported amounts of revenues and expenses during the reporting 
          period. Actual results could differ from these estimates.

     f.   RECLASSIFICATIONS

          Certain prior year balances have been reclassified to conform to 
          the 1996 presentation.

       In assessing the realizability of deferred tax assets, management
       considered whether it is more likely than not that some portion or all of
       the deferred tax assets will not be realized. The ultimate realization of
       deferred tax assets is dependent upon the generation of future taxable
       income during the periods in which those temporary differences become
       deductible and opportunities for carrybacks. Management considered the
       scheduled reversal of deferred tax liabilities, projected future taxable
       income, carryback opportunities and tax planning strategies in making
       this assessment. Based upon the results of operations of the current
       period and projections for future taxable income over the periods which
       the deferred tax assets are deductible, management believes it is more
       likely than not the Company will realize the benefits of these temporary
       deductible differences.

parts for commercial food service equipment;

          WHEREAS, the Boards of Directors of Parent, Merger Sub and the 
Company each have determined that it is in the best interests of their 
respective stockholders for Merger Sub to merge with and into the Company 
upon the terms and subject to the conditions of this Agreement;

          WHEREAS, Parent, Merger Sub, the Company and the Stockholder desire 
to make certain representations, warranties, covenants and agreements in

Agreement and the Delaware General Corporation Law ("DGCL"), at the Effective

Parent and the Company may agree, with the Secretary of State of the State of 
Delaware in the manner provided in the DGCL.  The Merger shall become 
effective on the close of business on the date on which the Certificate of 
Merger has been duly filed with the Secretary of State of the State of 
Delaware or such other time as is agreed upon by the parties and specified in 
the Certificate of Merger, and such time is hereinafter referred to as the 
"EFFECTIVE TIME."

          1.3  EFFECTS OF THE MERGER.  The Merger shall have the effects set 
forth in the DGCL.  Without limiting the generality of the foregoing, and 
subject thereto, at the Effective Time, all the properties, rights,

RIGHTS") to purchase shares of Series A Junior Participating Preferred Stock

                    (ii)  If the Net Worth as reflected on the Estimated
     Closing Balance Sheet is greater than $5,800,000, then the Estimated
     Closing Value shall be increased by an amount equal to the amount by
     which such Net Worth exceeds $5,800,000.

               (d)  The Company will cause to be delivered to Parent, two 
days prior to Closing, (i) an estimated balance sheet as of the Closing Date 
for the Company (the "ESTIMATED CLOSING BALANCE SHEET") to be prepared, in 
good faith and consistent with the requirements for the preparation of the 
Closing Date Balance Sheet (as hereinafter defined) pursuant to Section 4.2 
hereof and (ii) a certificate as to the preparation of the Estimated Closing 
Balance Sheet executed by the chief financial officer of the Company; 
PROVIDED, HOWEVER, that such Estimated Closing Balance Sheet will not be 
audited and will not include the inventory results required by Section 4.2(e) 
hereof.

               (e)  All Shares to be converted into Parent Shares pursuant to 
this Section 4.1 shall, by virtue of the Merger and without any action on the 
part of the holders thereof, cease to be outstanding, be canceled and retired 
and cease to exist, and each holder of a certificate representing any such 
Shares shall thereafter cease to have any rights with respect to such Shares, 
except the right to receive for each of the Shares, upon the surrender of 
such certificate in accordance with Section 4.3 hereof, the amount of Parent 
Shares specified above, as adjusted pursuant to Section 4.2 and Article 9 
hereof (the "MERGER CONSIDERATION").  Without limiting the generality of the 
foregoing, the Company and Parent agree that the Merger Consideration is 
subject to adjustment for any amounts payable pursuant to Section 4.2 and 
Article 9 hereof, to the extent of the Escrow Shares (as hereinafter 
defined).  

               (f)  At the Effective Time, each share of common stock of 
Merger Sub issued and outstanding immediately prior to the Effective Time 
shall, by virtue of the Merger and without any action on the part of Merger 
Sub or the holder thereof, be converted into and become one fully paid and 
nonassessable share of common stock of the Surviving Corporation.

               (g)  If, between the date of this Agreement and the Effective 
Time, the outstanding Parent Shares shall be changed into a different number 
of shares or a different class by reason of any reclassification, 
reorganization, consoli-


                                       5

dation, merger, recapitalization, split-up, stock-split, combination or 
exchange of shares or if a stock dividend thereon shall be declared with a 
record date within said period, the number of Parent Shares to be issued in 
the Merger shall be appropriately adjusted.

          4.2  PURCHASE PRICE ADJUSTMENT.

               (a)  After the Closing, the Estimated Closing Value shall be 
adjusted as follows:

                    (i)  If the amount equal to the total assets less total
     liabilities ("NET WORTH") set forth on the Adjusted Closing Date
     Balance Sheet (the "ADJUSTED NET BOOK VALUE") is less than the Net
     Worth of the Company set forth on the Estimated Closing Balance Sheet,
     then the stockholders of the Company shall surrender to Parent an
     amount of Escrow Shares equal to (A) the difference between (1) the
     Net Worth of the Company set forth on the Estimated Closing Balance
     Sheet and (2) the Adjusted Net Book Value, divided by (B) the Average
     Stock Price (the "SURRENDERED PARENT SHARES").  Pursuant to Section
     9.6 hereof and the terms of the Escrow Agreement (as hereinafter
     defined), the Escrow Agent (as hereinafter defined) shall be obligated
     to deliver Surrendered Parent Shares to Parent, within two business
     days following the determination of the Adjusted Closing Date Balance
     Sheet.

                    (ii)  If the Adjusted Net Book Value is greater than
     the Net Worth of the Company set forth on the Estimated Closing
     Balance Sheet, then the stockholders of the Company shall be entitled
     to receive additional Parent Shares (the "ADDITIONAL PARENT SHARES")
     in an amount equal to (A) the difference between (1) the Net Worth of
     the Company set forth on the Estimated Closing Balance Sheet and (2)
     the Adjusted Net Book Value, divided by (B) the Average Stock Price. 
     The Additional Parent Shares shall be distributed by Parent, within
     two business days following the determination of the Adjusted Closing
     Date Balance Sheet, to the stockholders of the Company, pro rata, in
     proportion to each of their holdings of Shares immediately prior to
     the Effective Time.

<PAGE>

               (b)  As soon as practicable, but in no event later than 60 
days following the Closing Date, Parent shall prepare or cause the 
Stockholder and/or the Company to prepare a balance sheet of the Company, as 
of the close of business on the Closing Date (including the notes thereto, 
the "CLOSING DATE BALANCE SHEET"), audited by Coopers & Lybrand, LLP, 
certified public accountants (the "ACCOUNTANTS"), on a basis consistent with 
the 1997 Balance Sheet (as hereinafter defined).  The Closing Date Balance 
Sheet shall be prepared in conformity with United States generally accepted 
accounting principles ("GAAP") in order to fairly present the financial 
position of the Company in accordance with GAAP; PROVIDED, HOWEVER, that (i) 
any liabilities related to employee benefit plans of the Company (including, 
without limitation, the employment and post-retirement arrangements with Mr. 
& Mrs. Parker Tyler) will be included in the Closing Date Balance Sheet as 
liabilities at their actuarially determined cost; (ii) the Closing Date 
Balance Sheet shall utilize the results of the physical inventory taken 
pursuant to Section 4.2(e) as adjusted for actual sales and purchase of 
inventory between the Inventory Date and the Closing Date; (iii) any amounts 
paid in connection with any severance or non-competition agreements between 
the Company and Sam Mazzilli and between the Company and Jim Rowland shall be 
valued at the appropriate tax-effected amount not to exceed $600,000.00; (iv) 
any loans from the Company to any stockholder of the Company which have been 
forgiven by the Company as reflected on the Company Disclosure Schedule shall 
be valued at an aggregate amount as reflected on the Company Disclosure 
Schedule; (v) no amounts will be accrued with respect to vacation 
compensation owed to employees of the Company through the Closing Date; (vi) 
any amounts related to any pending tax audit for the fiscal year 1995 shall 
be accrued on the Closing Date Balance Sheet; (vii) the value of assets may 
not be written up on the Closing Date Balance Sheet from the values set forth 
on the September 30, 1997 balance sheet of the Company; and (viii) no 
non-cash Settlement (as hereinafter defined), if any, shall be included in 
accordance with Section 6.1(a)(xiii) hereof. 

               (c)  Parent, or the Accountants, shall deliver a copy of the 
Closing Date Balance Sheet, together with the work papers used in the 
preparation thereof, to the Stockholder promptly after it has been prepared. 
After receipt of the Closing Date Balance Sheet, the Stockholder shall have 
30 days to review the Closing Date Balance Sheet, together with work papers 
used in the preparation thereof.  The Stockholder and his authorized 
representatives shall have full access to all relevant books and records and 
employees of the Company, Parent and the Accountants to the extent required 
to complete their review of the Closing Date Balance Sheet.  Unless the 
Stockholder delivers written notice to Parent on or prior to the 30th day 
after the Stockholder's receipt of the Closing Date Balance Sheet


                                       7

<PAGE>

specifying in reasonable detail all disputed items and the basis therefor, 
the Stockholder shall be deemed to have accepted and agreed to the Closing 
Date Balance Sheet.  If the Stockholder so notifies Parent of the 
Stockholder's objection to the Closing Date Balance Sheet, Parent and the 
Stockholder shall, within 30 days following the date of such notice (the 
"RESOLUTION PERIOD"), attempt to resolve their differences and any resolution 
by them as to any disputed amounts shall be final, binding and conclusive.  
If following resolution of any disputed amounts, there do not remain in 
dispute amounts the aggregate net effect of which exceeds $5,000, then all 
amounts remaining in dispute shall be deemed to have been resolved in favor 
of the Closing Date Balance Sheet delivered by Parent to the Stockholder.

               (d)  If at the conclusion of the Resolution Period, the 
aggregate net effect of all amounts remaining in dispute exceeds $5,000, then 
all amounts remaining in dispute shall be submitted to Arthur Andersen LLP, 
certified public accountants (the "NEUTRAL AUDITOR").  Each party agrees to 
execute, if requested by the Neutral Auditor, a reasonable engagement letter. 
 All fees and expenses relating to the work, if any, to be performed by the 
Neutral Auditor shall be borne by the losing party.  The Neutral Auditor 
shall act as an arbitrator to determine, based solely on presentations by 
Parent, the Company and the Stockholder, and not by independent review, only 
those issues remaining in dispute.  The Neutral Auditor's determination shall 
be made within 30 days of its engagement, shall be set forth in a written 
statement delivered to Parent and the Stockholder and shall be final, binding 
and conclusive.  The term "ADJUSTED CLOSING DATE BALANCE SHEET," as used in 
this Agreement, shall mean the definitive Closing Date Balance Sheet agreed 
to by the Stockholder and Parent in accordance with Section 4.2(c) hereof or 
the definitive Closing Date Balance Sheet resulting from the determinations 
made by the Neutral Auditor in accordance with this Section 4.2(d) (in 
addition to those items theretofore agreed to by Parent and the Stockholder), 
in each case prepared in the manner set forth in the last sentence of Section 
4.2(b) hereof.

               (e)  On a date or dates mutually agreeable to the parties, and 
in any event within five days prior to or five days following the Closing 
Date (the "INVENTORY DATE"), the Stockholder and/or the Company will take a 
physical inventory at each and every location of the Company, observed by 
Parent, the Accountants and/or their representative.  The inventory shall 
only include parts which (i) do not infringe third party Proprietary Rights 
(as hereinafter defined) or other property rights; (ii) meet the Company's 
specifications and industry standards applicable to such inventory and (iii) 
are usable and saleable in the ordinary course of the Com-


                                       8

<PAGE>

pany's business, as presently conducted by the Company.  Said physical 
inventory shall list the type and quantity of the inventory as of the 
Inventory Date. 

               (f)  In order to facilitate the carrying out the terms of this 
Agreement and the Escrow Agreement, including the determination of any 
adjustment to the Merger Consideration pursuant to this Section 4.2 and 
Article 9 hereof, the Company hereby irrevocably makes, constitutes and 
appoints the Stockholder as its agent and representative (in this capacity, 
the "STOCKHOLDER REPRESENTATIVE"), with full power of substitution, for 
purposes of carrying out the terms of this Section 4.2 and Article 9 hereof.  
The Company agrees that the Stockholder Representative may be reimbursed out 
of the Escrow Fund, in accordance with the Escrow Agreement, for all 
reasonable expenses, disbursements and advances incurred or made by the 
Stockholder Representative in the good-faith performance of his duties as the 
Stockholder Representative hereunder; provided, however, that any such 
payment shall be made only after any pending claims, if any,  for which 
Parent seeks indemnification shall have been fully paid and prior to final 
distribution of any remaining Escrowed Shares, if any, to former stockholders 
of the Company.  The Company agrees that it will not pursue any action 
against the Stockholder Representative, in his capacity as the Stockholder 
Representative, on behalf of the former stockholders of GCS; PROVIDED, 
HOWEVER, that the Stockholder Representative has acted in good faith and in 
his own best judgement.

          4.3  EXCHANGE OF SHARES IN THE MERGER.

               (a)  EXCHANGE AGENT.  Following the Effective Time, Parent 
shall deposit, or shall cause to be deposited, with a third party selected by 
Parent and reasonably acceptable to the Company (the "EXCHANGE AGENT"), for 
the benefit of the stockholders of the Company, for exchange in accordance 
with this Section 4.3, certificates representing the Parent Shares, less the 
Escrow Shares, pursuant to the terms of the Escrow Agreement and Section 9.6 
hereof (such certificates for Parent Shares being hereinafter referred to as 
the "EXCHANGE FUND") to be issued pursuant to Section 4.1 hereof in exchange 
for the Shares.

               (b)  EXCHANGE PROCEDURES.  As soon as practicable after the 
Effective Time, the Exchange Agent shall mail to each holder of record of an 
outstanding certificate which, prior to the Effective Time, represented a 
Share (a "CERTIFICATE") (i) a letter of transmittal (which shall specify that 
delivery shall be effected, and risk of loss and title to the Certificates 
shall pass, only upon delivery of the Certificates to the Exchange Agent) and 
(ii) instructions for use in effecting the


                                       9

<PAGE>

surrender of the Certificates in exchange for certificates representing 
Parent Shares.  Upon surrender of a Certificate for cancellation to the 
Exchange Agent or Parent, together with such letter of transmittal, duly 
executed, the holder of such Certificate(s) shall be entitled to receive in 
exchange therefor a Parent certificate representing that number of Parent 
Shares into which the Shares have been converted pursuant to Section 4.1 
hereof less the number of Parent Shares required to be deposited into escrow 
pursuant to Section 9.6 hereof and the Certificate so surrendered shall be 
cancelled.  If any certificate representing Parent Shares is to be issued in 
a name other than that in which the Certificate surrendered in exchange 
therefor is registered, it shall be a condition of the issuance thereof that 
the Certificate so surrendered shall be properly endorsed (or accompanied by 
an appropriate instrument of transfer) and otherwise in proper form for 
transfer, and that the person requesting such exchange shall pay to the 
Exchange Agent in advance any transfer or other taxes required by reason of 
the issuance of a certificate representing Parent Shares in any name other 
than that of the registered holder of the Certificate surrendered, or 
required for any other reason, or shall establish to the satisfaction of the 
Exchange Agent that such tax has been paid or is not payable.  Until 
surrendered as contemplated by this Section 4.3, each Certificate shall be 
deemed at any time after the Effective Time to represent only the right to 
receive upon such surrender the certificate representing Parent Shares into 
which the Shares have been converted.

               (c)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No 
dividends or other distributions declared with respect to Parent Shares and 
payable to the holders of record thereof after the Effective Time shall be 
paid to the holder of any unsurrendered Certificate until the holder thereof 
shall surrender such Certificate in accordance with this Article 4.  After 
the surrender of a Certificate in accordance with this Article 4, the record 
holder thereof shall be entitled to receive any such dividends or other 
distributions, without any interest thereon, which theretofore had become 
payable with respect to Parent Shares represented by such Certificate.  No 
holder of an unsurrendered Certificate shall be entitled, until the surrender 
of such Certificate, to vote the Parent Shares into which Shares shall have 
been converted.

               (d)  LOST OR STOLEN SHARES.  In the event any Certificate 
shall have been lost, stolen or destroyed, upon the making of an affidavit of 
that fact by the person claiming such Certificate to be lost, stolen or 
destroyed and, if required by Parent, in accordance with its normal and 
customary procedures, the posting by such person of a bond in such amount as 
Parent may direct as indemnity against any claim that may be made against it 
with respect to such Certificate, the Exchange Agent will


                                       10


<PAGE>

issue in exchange for such lost, stolen or destroyed Certificate the Parent 
Shares deliverable in respect thereof pursuant to this Agreement.

               (e)  NO FURTHER OWNERSHIP RIGHTS IN THE SHARES.  After the 
Effective Time, there shall be no transfers on the stock transfer books of 
the Company of the Shares which were issued and outstanding immediately prior 
to the Effective Time.  If, after the Effective Time, Certificates 
representing such shares are presented for transfer to the Exchange Agent, 
they shall be cancelled and exchanged for certificates representing Parent 
Shares as provided in this Article 4.

          4.4  RETURN OF EXCHANGE FUND.  Any portion of the Exchange Fund 
that remains unclaimed by the stockholders of the Company for twenty-four 
(24) months after the Effective Time shall be paid to Parent.  Any 
stockholders of the Company who have not theretofore complied with this 
Article 4 shall thereafter look only to Parent for payment of their Parent 
Shares and any unpaid dividends and distributions on the Parent Shares 
deliverable in respect of each Share such stockholder holds as determined 
pursuant to this Agreement, without any interest thereon.  Any portion of the 
Escrow Shares that remains unclaimed by the stockholders of the Company for 
thirty-six (36) months after the Effective Time shall be paid to Parent.  
Notwithstanding the foregoing, none of Parent, the Company, the Exchange 
Agent or any other person shall be liable to any former holder of Shares for 
any amount properly delivered to a public official pursuant to applicable 
abandoned property, escheat or similar laws.

          4.5  FRACTIONAL SHARES.  No fractional Parent Shares shall be 
issued in the Merger or returned to Parent pursuant to Section 4.2.  Each of 
the stockholders of the Company who would otherwise have been entitled to a 
fraction of a Parent Share upon surrender of certificates for exchange 
pursuant to this Article 4 will be issued one additional Parent Share.  If 
Parent is otherwise entitled to a fractional Surrendered Parent Share, Parent 
will receive the next lower whole number of Surrendered Parent Shares.

          4.6  TRANSFER OF SHARES.  The Stockholder agrees not to sell, 
pledge, encumber or otherwise transfer his Shares except in accordance with 
the terms of this Agreement.

          4.7  DISSENTING SHARES.  Notwithstanding anything in this Agreement 
to the contrary, shares of the Company which immediately prior to the 
Effective Time are held by stockholders who have properly exercised and 
perfected dissenters'


                                       11


<PAGE>

rights under Section 262 of the DGCL (the "DISSENTING SHARES") shall not be 
converted into the right to receive Parent Shares as provided in Section 4.1 
hereof, but the holders of Dissenting Shares shall be entitled to receive 
consideration as shall be determined pursuant to Section 262 of the DGCL; 
PROVIDED, HOWEVER, that if any such holder shall have failed to perfect or 
shall withdraw or lose dissenter's rights, such holder's shares shall 
thereupon be deemed to have been converted into Parent Shares as of the 
Effective Time, without any interest thereon, as provided in Section 4.1 
hereof, and such shares shall no longer be Dissenting Shares.

          4.8  STOCK OPTIONS.  The Company shall take all action as may be 
necessary to cause each holder of unexpired and unexercised options granted 
under the 1992 Stock Option and Restricted Stock Plan of GCS Service, Inc., 
as amended (each a "COMPANY OPTION"), to exercise in full or terminate, on or 
prior to the date hereof, all Company Options held by such stockholder.  At 
the Effective Time, each Company Option to purchase Shares which is 
outstanding and unexercised immediately prior thereto, shall be cancelled and 
all rights thereunder shall be extinguished.

                                      ARTICLE 5

                            REPRESENTATIONS AND WARRANTIES

          5.1  REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE 
STOCKHOLDER.  The Company and the Stockholder, jointly and severally, 
represent and warrant to Parent and Merger Sub as follows:

               (a)  CORPORATE ORGANIZATION AND QUALIFICATION.

                    (i)  The Company is a corporation duly organized,
     validly existing and in good standing under the laws of its
     jurisdiction of incorporation and is qualified and in good standing as
     a foreign corporation in each jurisdiction where the properties owned,
     leased or operated, or the business conducted by it require such
     qualification, except where failure to so qualify or be in good
     standing would not have a Material Adverse Effect (as hereinafter
     defined) on the Company.  The Company has all requisite power and
     authority (corporate or otherwise) to own its properties and to carry
     on its business as it is now being conducted.  The Company has
     heretofore


                                       12


<PAGE>


     provided to Parent true and complete copies of the Company's
     Certificate of Incorporation and Bylaws as currently in effect.

                    (ii)  Southern Appliance Parts Company, Inc. ("SOUTHERN
     APPLIANCE") is the only corporation in which the Company, directly or
     indirectly, beneficially owns any shares of capital stock, partnership
     interests or limited liability company interests.  Southern Appliance
     conducts no operations and has no liabilities or obligations of any
     nature.  For purposes of this Article V and Article VI hereof, the
     "Company" shall be deemed to include Southern Appliance.

               (b)  CAPITALIZATION.  The authorized capital stock of the Company
consists of 500,000 shares of common stock, $.01  par value per share, of which
147,118 shares are issued and outstanding, excluding 185,818 shares held in
treasury and options to purchase 14,025 shares of common stock of the Company,
subject to Section 4.8 hereof.  All of the outstanding shares of capital stock
of the Company have been duly authorized and validly issued and are fully paid
and nonassessable.  The only holders of record and the only beneficial owners of
Shares are as set forth in Section 5.1(b) of the Company Disclosure Schedule (as
hereinafter defined).  Except as set forth in Section 5.1(b) on the Company
Disclosure Schedule, none of the Shares are subject to any option, warrant, put
right or call, preemptive right or commitment of any kind or character.  There
are not as of the date hereof, and there will not be at the Effective Time, any
outstanding or authorized options, warrants, calls, put rights, commitments or
any other agreements of any character requiring the Company or any stockholder
of the Company to issue, transfer, sell, purchase, redeem or acquire Shares or
any shares of capital stock or any securities or rights convertible into,
exchangeable for, or evidencing the right to subscribe for, any shares of
capital stock of the Company or its subsidiary.  The Stockholder, and to the
knowledge of the Stockholder, the stockholders of the Company, have and will
have at the Effective Time, good and marketable title to the Shares, free and
clear of any and all Liens (as hereinafter defined).  Except as set forth in
Section 5.1(b) of the Company Disclosure Schedule, neither the Company nor the
Stockholder has received any notice of any adverse claim to the ownership of any
Shares and does not have any reason to know of any such adverse claims that may
be justified.  Except as set forth in Section 5.1(b) of the Company Disclosure
Schedule, there are no stockholder agreements, buy-sell agreements, voting
trusts or other agreements or understandings to which the Company or any of the
stockholders of the Company is a


                                       13


<PAGE>

party or to which it or any of them is bound relating to the voting of any 
shares of the capital stock of the Company.

               (c)  APPROVALS; FAIRNESS OPINIONS.

                    (i)  The Board of Directors of the Company, at a
     meeting duly called and held, has, in light of and subject to the
     terms and conditions set forth herein, (A) determined that this
     Agreement, the Merger and the other transactions contemplated hereby
     are fair to, and in the best interests of, all of the stockholders of
     the Company, (B) approved this Agreement, the Merger and the other
     transactions contemplated hereby and (C) resolved to recommend
     approval and adoption of this Agreement, the Merger and the other
     transactions contemplated hereby to all of the stockholders of the
     Company.

                    (ii)  The Board of Directors of the Company has
     received (or will have received prior to the Closing) an opinion from
     Carter Capital Corporation, the Company's financial advisor, to the
     effect that, as of the date of such opinion, the consideration to be
     received by the stockholders of the Company in the Merger is fair to
     all of the stockholders of the Company from a financial point of view. 
     Such opinion has not been (and will not have been prior to the
     Closing) withdrawn, revoked or modified.  A true and complete copy of
     such opinion will be delivered to Parent at the Closing.

               (d)  AUTHORITY RELATIVE TO THIS AGREEMENT. The Stockholder has 
the full right, power and authority to execute and deliver this Agreement, 
the Escrow Agreement and any other agreement, certificate or other instrument 
required to be delivered in connection with this Agreement (collectively, the 
"ANCILLARY AGREEMENTS") and to consummate the transactions contemplated 
hereby and thereby. The Company has the requisite corporate power and 
authority to approve, authorize, execute and deliver this Agreement and the 
other Ancillary Agreements and, upon approval of its stockholders in 
accordance with the law, to consummate the transactions contemplated hereby 
and thereby, including, without limitation, the Merger.  This Agreement and 
the other Ancillary Agreements and the consummation by the Company of the 
transactions contemplated hereby and thereby have been duly and validly 
authorized by the Board of Directors of the Company and the Board of 
Directors of the Company will recommend approval of this Agreement by the 


                                       14

<PAGE>

Company's stockholders at the Special Meeting described in Section 6.12 
hereof.  No other corporate proceedings on the part of the Company or the 
stockholders of the Company are necessary to authorize this Agreement or to 
consummate the transactions contemplated hereby, other than the approval and 
adoption of this Agreement by stockholders holding a majority of the Shares 
entitled to vote thereon.  This Agreement and the other Ancillary Agreements 
have been, and will be, duly and validly executed and delivered by the 
Company and the Stockholder and, assuming this Agreement and the other 
Ancillary Agreements constitute the valid and binding agreements of Parent, 
Merger Sub and the Escrow Agent, as applicable, constitute the valid and 
binding agreement of the Company and the Stockholder, enforceable against the 
Company and the Stockholder in accordance with their terms.

               (e)  NO VIOLATION.  Neither the execution and delivery of this 
Agreement nor the other Ancillary Agreements by the Company and the 
Stockholder and the performance by each of the Company and the Stockholder of 
their respective obligations hereunder and thereunder nor the consummation by 
the Company or the Stockholder of the transactions contemplated hereby and 
thereby will (i) violate, conflict with or result in any breach of any 
provision of the Certificate of Incorporation or Bylaws of the Company; (ii) 
except as set forth in Section 5.1(e) of the written statement delivered by 
the Company on or prior to the date hereof (the "COMPANY DISCLOSURE 
SCHEDULE"), violate, conflict with or result in a violation or breach of, or 
constitute a default (with or without due notice or lapse of time or both) 
under, or permit the termination of, or result in the acceleration of, or 
entitle any party to accelerate (whether as a result of a change in control 
of the Company or otherwise) any obligation, or result in the loss of any 
benefit, or give rise to the creation of any Liens upon any of the respective 
properties or assets of the Company under any of the terms, conditions or 
provisions of any contract, agreement, license, lease or other instrument or 
obligation to which the Company or the Stockholder are a party or by which 
they or any of their respective properties or assets may be bound or affected 
or (iii) violate any order, writ, judgment, injunction, decree or, to the 
knowledge of the Company, any statute, rule or regulation of any court or 
governmental authority, applicable to the Company or, to the knowledge of the 
Stockholder, the stockholders of the Company or any of their respective 
properties or assets.

     "employee benefit plan" (within the meaning of Section 3(3) of the
     Employee Retirement Income Security Act of 1974, as amended, and the
     rules and regulations promulgated thereunder ("ERISA")), whether
     formal or informal, written or oral and whether legally binding or
     not, that is sponsored, maintained or contributed to or was sponsored,
     maintained or contributed to at any time by the Company or by any
     trade or business, whether or not incorporated which together with the
     Company would be deemed a "single employer" within the meaning of
     Section 4001 of ERISA (an "ERISA AFFILIATE"), within the last six
     years, for the benefit of any employee, former employee, consultant,
     officer or director of the Company or any ERISA Affiliate (a "BENEFIT
     PLAN").

                    (ii)  With respect to each Benefit Plan, the Company
     has heretofore delivered to Parent true and complete copies of each of

                                       23


<PAGE>

                         (C)  a copy of any actuarial report, including any
     actuarial report required under ERISA or other applicable law, with respect
     to each such Benefit Plan for the three most recently completed plan years;

                         (D)  a copy of the most recent Summary Plan
     Description, together with each Summary of Material Modifications, if
     required under ERISA with respect to each such Benefit Plan, and all
     material employee communications relating to each such Benefit Plan;

                         (E)  if the Benefit Plan is funded through a trust or
     any third party funding vehicle, a copy of the trust or other funding
     agreement (including all amendments thereto) and the latest financial
     statements thereof;

                         (F)  all contracts relating to any Benefit Plan with
     respect to which the Company or any ERISA Affiliate may have any liability,
     including, without limitation, insurance contracts, investment management
     agreements, subscription and participation agreements and record keeping or
     other servicing or administration agreements; and

                         (G)  the most recent determination letter received from
     the Internal Revenue Service with respect to each Benefit Plan that is
     intended to be qualified under Section 401 of the Code.

                    (iii)  No Benefit Plan is a "multiemployer plan," as
     such term is defined in Section (3)(37) of ERISA or a "multiple
     employer plan" within the meaning of Section 4063 or 4064 of ERISA;
     each of the Benefit Plans is, and has always been, operated in all
     material respects in accordance with the requirements of all
     applicable law; each of the Benefit Plans intended to be "qualified"
     within the meaning of Section 401(a) of the Code is so qualified and
     has received a favorable determination letter from the Internal
     Revenue Service to that effect; no Benefit Plan has an accumulated or
     waived funding deficiency within the meaning of Section 412 of the
     Code; neither the Company nor any ERISA Affiliate has incurred,
     directly or indirectly, any liability (including any material
     contingent liability) to or on account of a Benefit Plan pursuant to

     any Benefit Plan that is


                                       24

<PAGE>

     subject to Title IV of ERISA; no "reportable event," as such term is 
     defined in Section 4043(b) of ERISA, has occurred with respect to any 
     Benefit Plan; and no condition exists that presents a material risk to 
     the Company or any ERISA Affiliate of incurring a liability to or on 
     account of a Benefit Plan pursuant to Title IV of ERISA.

                    (iv)  The current value of the assets of each of the
     Benefit Plans that is subject to Title IV of ERISA exceeds the present
     value of the accrued benefits under each such Benefit Plan, based upon
     the actuarial assumptions used for funding purposes in the most recent
     actuarial report prepared for such Benefit Plan.  Full payment has
     been made, or will be made in accordance with section 404(a)(6) of the
     Code, of all amounts which the Company or any ERISA Affiliate is
     required to pay under the terms of each of the Benefit Plans as of the
     last day of the most recent plan year thereof ended prior to the date
     of this Agreement, and all such amounts properly accrued through the
     Closing Date with respect to the current plan year thereof will be
     paid by the Company on or prior to the Closing Date or will be
     properly reflected on the Adjusted Closing Date Balance Sheet.

                    (v)  No Benefit Plan provides benefits, including,
     without limitation, death or medical benefits (whether or not
     insured), with respect to current or former employees of the Company
     or any ERISA Affiliate for periods extending beyond their retirement
     or other termination of service (other than (A) coverage mandated by
     applicable law; (B) death benefits or retirement benefits under any
     "employee pension plan," as that term is defined in Section 3(2) of
     ERISA; (C) deferred compensation benefits accrued as liabilities on
     the books of the Company or an ERISA Affiliate or (D) benefits the
     full cost of which is borne by the current or former employee (or his
     beneficiary)).  No amounts payable under the Benefit Plans will fail
     to be deductible for Federal income tax purposes by virtue of Section
     280G of the Code.

                    (vi)  There has been no prohibited transaction (within
     the meaning of Section 406 of ERISA or Section 4975 of the Code) with
     respect to any Benefit Plan; the Company has not incurred any
     liability for any excise tax arising under Section 4972 or 4980B of


                                       25

<PAGE>


     the Code and no fact or event exists that could give rise to any such
     liability with respect to the filing of reports with respect to any
     Benefit Plan; there are no pending, threatened or anticipated claims
     (other than routine claims for benefits) by, on behalf of or against
     any of the Benefit Plans, or any trusts related thereto or any trustee
     or administrator thereof, and no litigation or administrative or other
     proceeding (including, without limitation, any litigation or
     proceeding under Title IV of ERISA) has occurred or, to the best of
     the Company's or the Stockholder's knowledge, is threatened involving
     any Benefit Plan or any trusts related thereto or any trustee or
     administrator thereof.

                    (vii)  Except as set forth in Section 5.1(l)(vii) of
     the Company Disclosure Schedule, the consummation of the transactions
     contemplated by this Agreement will not (A) entitle any current or
     former employee or officer of the Company or any of its subsidiaries

unenforceable in scope, the Stockholder, Parent and the Company consent to the
exercise by such court of its equitable jurisdiction to reform such terms in
accordance with applicable law.

               (g)  The Stockholder agrees that if he breaches any provision of
this Section 6.10, the damage to Parent or the Company would be difficult to
ascertain, and money damages would not afford Parent or the Company an adequate
remedy.  Therefore, if the Stockholder is in breach of this Section 6.10, the
parties 



                                            48

hereto agree that Parent or the Company shall be entitled, in addition to any 
and all rights and remedies as would be provided by law, to specific 
performance, injunctive, and other equitable relief to prevent or restrain a 
breach of this Section 6.10.  The rights of Parent or the Company under this 
Section 6.10 are in addition to, and not in lieu of, any and all rights 
Parent or the Company may have at law or in equity to protect its business 
interests. The Stockholder agrees to be liable for any and all costs and 
expenses, including attorneys fees, resulting from the breach by the 
Stockholder of any provision of this Section 6.10.

               (h)  Parent acknowledges that any damages that may be sought 
by Parent due to any breach on the part of the Stockholder of the terms of 
this Section 6.10 may not be sought from any amounts held in escrow pursuant 
to Section 9.6 hereof.

Statement.  Parent agrees that the Registration Statement and each amendment 
or supplement thereto at the time it is filed or becomes effective, and at 
the time that the Proxy Statement/Prospectus which forms a part thereof is 
mailed to the stockholders of the Company, will not include an untrue 
statement of a material fact or omit to state a material fact required to be 
stated therein or necessary to make the statements therein, in light of the 
circumstances under which they were made, not misleading; PROVIDED, HOWEVER, 
that the foregoing shall not apply to the extent that any such untrue 
statement of a material fact or omission to state a material fact was made by 
Parent in reliance upon and in conformity with written information concerning

of the Company, will not contain an untrue statement of a material fact or

such recommendations; and shall use its best efforts to obtain such 
stockholder approval.  The Company shall coordinate and cooperate with Parent

then the Company shall promptly (and in any event within five (5) business 
days after such termination) pay Parent a fee equal to $900,000.

          6.14  CERTAIN CLAIMS; ALLOCATION OF RECOVERY.  The Parent, in its 
sole and absolute discretion, may elect to, or cause the Company to, pursue

PROVIDED, HOWEVER, that until Parent recovers full payment of its Loss, any

on account of such payment are hereby made expressly subordinated and 
subjected in right of payment of Parent's rights against such third party. 

          9.6  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All of the 
representations and warranties of the parties contained in this Agreement or

years after the Closing, the representations and warranties contained in 
Sections 5.1(m) and 5.1(o) shall survive until the applicable statutes of

brought with respect to any claims hereunder unless written notice thereof, 
setting forth in reasonable detail each such claim, shall have been sent to 
the applicable party prior to the expiration of the applicable periods set 
forth above.  The right to indemnification or any other remedy based on 
representations, warranties, covenants and obligations in this Agreement will 
not be affected by any investigation conducted with respect to, or any 
knowledge acquired (or capable of being acquired) at any time, whether before 
or after the execution and delivery of this Agreement or the Closing Date, 


                                       59

with respect to the accuracy or inaccuracy of or compliance with, any such 
representation, warranty, covenant or obligation.  The waiver of any 
condition based on the accuracy of any representation or warranty, or on the 
performance of or compliance with any covenant or obligation, will not affect 
the right to indemnification or any other remedy based on such 
representations, warranties, covenants and obligations.

          9.7  ESCROW AGREEMENT.  Subject to the terms and conditions of an 
escrow agreement (the "ESCROW AGREEMENT") in substantially the form as is set

("ESCROW AGENT"), Parent Shares in an aggregate amount equal to the sum of 
ten percent (10%) of the Merger Consideration owing to each holder of a 
certificate representing Parent Shares to be issued in connection with the 
transactions contemplated by Section 4.1 of this Agreement (the "ESCROW 
AMOUNT") shall be deposited with the Escrow Agent pursuant to the terms of 
the Escrow Agreement for the term of two years as collateral for the 
indemnification of Parent and/or Merger Sub of possible claims pursuant to 
Sections 4.2, 9.1 or 9.2 hereof (the "ESCROW SHARES"); it being understood 
that such stockholders shall have all voting rights with respect to the 
Escrow Shares and shall receive on a current basis all dividends and 
distributions on the Escrow Shares.  In the event Escrow Shares are returned 
to Parent and/or Merger Sub for any purchase price adjustment pursuant to 
Section 4.2 hereof or the indemnification of any claim(s) pursuant to Article 
9 hereof, such Escrow Shares shall be valued, per share, at the Average Stock 
Price.  In the event that any Escrow Shares are returned to Parent or Merger 
Sub for the indemnification of any claims pursuant to Article 9 hereof, such 
Escrow Shares shall be valued at the Fair Market Value.

          9.8  REMEDIES CUMULATIVE.  The remedies provided herein shall be 
cumulative and shall not preclude an indemnified party from asserting any 
other rights or seeking any other remedies against the indemnifying party or 
its successors or assigns.

                              FORM OF AFFILIATE LETTER



                              ______, 1998



Ecolab Inc.
Ecolab Center
370 N. Wabasha Street
St. Paul, Minnesota  55012

Gentlemen:

          I am a holder of shares of common stock, $.01 par value per share 
("Company Common Stock"), of GCS Service, Inc., a Delaware corporation (the 
"Company").  I am aware that pursuant to the terms of the Agreement and Plan 
of Merger, dated as of May __, 1998 (the "Agreement") among the Company, 
Ecolab Inc., a Delaware corporation ("Ecolab"), GCS Acquisition Corporation, 
a Delaware corporation ("Merger Sub") and Wesley B. Tyler, Merger Sub will be 
merged (the "Merger") with and into the Company with the Company continuing 
as the surviving corporation, and each of the shares of Company Common Stock 
owned by me as of the time of such Merger shall be converted into shares of 
common stock, par value $1.00 per share ("Ecolab Common Stock"), of Ecolab.

          I understand and agree that it is intended that the Merger will be 
treated as a tax free "reorganization" for federal income tax purposes.  I 
have been advised that as of the date hereof, I may be deemed an "affiliate" 
of the Company, within the meaning of Rule 145 ("Rule 145") promulgated under 
the Securities Act of 1933, as amended (the "Securities Act"), although 
nothing contained herein should be construed as an admission of such fact.  

          If in fact I am deemed an "affiliate" of the Company under the 
Securities Act, my ability to sell, assign or transfer Ecolab Common Stock 
received by me in exchange for any shares of Company Common Stock pursuant to 
the Merger may be restricted unless such transaction is registered under the 
Securities Act or an exemption from such registration is available.  I 
understand that such exemptions are limited and I have obtained advice of 
counsel as to the provisions of this letter agreement as well as the nature 
and conditions of such exemptions,

<PAGE>

including information with respect to the applicability to the sale of such 
securities of Rule 145(d) promulgated under the Securities Act, to the extent 
applicable.

          I understand that the representations and warranties and covenants 
set forth herein will be relied upon by the Company, Ecolab, their respective 
counsel and accounting firms and stockholders of the Company and Ecolab.     

          In connection with the above transactions, I represent and warrant 
to Ecolab and agree that:

          A.  I have been advised that the issuance of Ecolab Common Stock to 
me pursuant to the Merger will be registered with the Securities and Exchange 
Commission (" SEC") under the Securities Act on a Registration Statement on 
Form S-4. However, I have also been advised that because I may be deemed to 
have been an "affiliate" of the Company at the time the Merger was submitted 
for a vote of the stockholders of the Company, and because any distribution 
by me of Ecolab Common Stock has not been registered under the Securities 
Act, I may not sell, transfer, exchange, pledge, or otherwise dispose of, or 
make any offer or agreement relating to any of the foregoing with respect to, 
the Ecolab Common Stock acquired by me pursuant to the Merger, or any 
securities that may be paid as a dividend or otherwise distributed thereon or 
with respect thereto or issued or delivered in exchange or substitution 
therefor (all such shares and other securities of Ecolab being herein 
sometimes collectively referred to as "Restricted Securities"), or any 
option, right or other interest with respect to any Restricted Securities, 
unless (i) such transaction is permitted pursuant to Rules 145(c) and 145(d) 
under the Securities Act, (ii) counsel reasonably satisfactory to Ecolab, 
shall have advised Ecolab in a written opinion letter satisfactory to Ecolab 
and Ecolab's legal counsel, and upon which Ecolab and its legal counsel may 
rely, that no registration under the Securities Act would be required in 
connection with the proposed sale, transfer or other disposition, (iii) a 
registration statement under the Securities Act covering the Restricted 
Securities proposed to be sold, transferred or otherwise disposed of, 
describing the manner and terms of the proposed sale, transfer or other 
disposition, and containing a current prospectus, shall have been filed with 
the SEC and made effective under the Securities Act, or (iv) an authorized 
representative of the SEC shall have rendered written advice to me (sought by 
me or counsel representing me, with a copy thereof and all other related 
communications delivered to Ecolab) to the effect that the SEC would take no 
action, or that the Staff of the SEC would not recommend that the SEC take 
action, with respect to the proposed disposition if consummated.

          B.  I understand that Ecolab is under no obligation to register the 
sale, transfer or other disposition of Restricted Securities by me or on my 
behalf under the Securities Act or, except as set forth in the following 
paragraph, to take any other ac-

                                       2
<PAGE>

tion necessary in order to make compliance with an exemption from such 
registration available.

          C.  From and after the effective date of the Merger (the "Effective 
Time") and for so long as is necessary in order to permit me to sell the 
Restricted Securities held by and pursuant to Rule 145 and, to the extent 
applicable, Rule 144 under the Securities Act, Ecolab will use its best 
efforts to file on a timely basis all reports required to be filed by it 
pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, 
referred to in paragraph (c)(1) of Rule 144 under the Securities Act.  Ecolab 
is under no obligation to register the sale, transfer or other disposition of 
any Restricted Securities by me or on my behalf or to take any other action 
necessary (other than pursuant to the preceding sentence) in order to make 
compliance with an exemption from registration available.

          D.  I understand that, in addition to the restrictions imposed 
under this agreement, the provisions of Rule 145 limit any public resale by 
me of Restricted Securities and that the restrictive legends described below 
will be placed upon the Restricted Securities.

     I understand that stop transfer instructions will be given to the 
registrar of the certificates for the shares of Ecolab Common Stock and that 
there will be placed on the certificates for the shares of Ecolab Common 
Stock, or any substitutions therefor, a legend stating in substance:

          THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
          TRANSACTION (THE ACQUISITION OF GCS SERVICE, INC.) TO WHICH
          RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS
          AMENDED (THE "ACT"), APPLIES AND MAY BE SOLD OR OTHERWISE
          TRANSFERRED ONLY IN COMPLIANCE WITH THE LIMITATIONS OF SUCH
          RULE 145, OR UPON RECEIPT BY ECOLAB INC., OF AN OPINION OF
          COUNSEL ACCEPTABLE TO IT THAT SOME OTHER EXEMPTION FROM
          REGISTRATION UNDER THE ACT IS AVAILABLE, OR PURSUANT TO A
          REGISTRATION STATEMENT UNDER THE ACT.  

          Ecolab agrees to remove such legend to the extent that shares
evidenced by such certificates may properly be sold by me pursuant to this
agreement.

                                       3
<PAGE>

          2.  I also understand that unless a sale or transfer is made in 
conformity with the provisions of Rule 145, or pursuant to a registration 
statement, Ecolab reserves the right to put the following legend on the 
certificates issued to my transferee:

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE
          ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A
          TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE
          SECURITIES ACT OF 1933 APPLIES.  THE SHARES HAVE BEEN
          ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN
          CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING
          OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED
          OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH AN
          EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
          SECURITIES ACT OF 1933 OR PURSUANT TO A REGISTRATION
          STATEMENT UNDER THE SECURITIES ACT OF 1933.  

          E.  I hereby agree that, for a period of one (1) year following the 
Effective Time of the Merger, I will obtain an agreement similar to this 
agreement from each transferee of the shares of Ecolab Common Stock sold or 
otherwise transferred by me, but only if such sale or transfer is effected 
other than in a transaction involving a registered public offering or as a 
sale pursuant to Rule 145.

          It is understood and agreed that this agreement will terminate and 
be of no further force and effect and the legends set forth in Paragraph D 
above will be removed by delivery of substitute certificates without such 
legends, and the related transfer restrictions shall be lifted forthwith, if 
(i) my shares of Ecolab Common Stock shall have been registered under the 
Securities Act for sale, transfer, or other disposition by me or on my 
behalf, (ii) I am not at the time an "affiliate" (as defined in Rule 
144(a)(1) under the Securities Act) of Ecolab and have held the shares of 
Ecolab Common Stock for at least one (1) year (or such other shorter period 
as may be prescribed by the Securities Act and the Rules and Regulations) and 
Ecolab has filed with the SEC all of the reports it is required to file under 
the Securities Exchange Act of 1934, as amended, during the preceding twelve 
(12) months, (iii) I am not and have not been for at least three (3) months 
an "affiliate" of Ecolab and I have

                                       4
<PAGE>

held the shares of Ecolab Common Stock for at least two (2) years, or (iv) 
Ecolab shall have received a letter from the staff of the SEC, or an opinion 
of counsel acceptable to Ecolab, to the effect that the stock transfer 
restrictions and the legend are not required.

          This agreement may be executed in several counterparts, each of which
shall constitute one in the same instrument.

                                       5
<PAGE>

          This agreement shall be binding on my heirs, legal representatives,
and successors.

                              Very truly yours,

                            FORM OF OPINION OF COUNSEL TO 
                           THE COMPANY AND THE STOCKHOLDER


     Based upon and subject to the foregoing, and the further limitations and 
qualifications set forth below, we are of the opinion that:

     1.   The Company is a corporation validly existing and in good standing 
under the laws of the State of Delaware and has all requisite corporate power 
and authority to own its properties and to carry on its business as it is now 
being conducted.

     2.   The authorized capital stock of the Company consists solely of 
500,000 shares of common stock, par value $.01 per share, of which only the 
Shares are issued and outstanding.  All of the outstanding shares of capital 
stock of the Company have been duly authorized and validly issued and are 
fully paid and nonassessable.  The only holders of record of the Shares are 
as set forth on Exhibit A, attached hereto.  To the best knowledge of 
Counsel, there are not, as of the date hereof, any outstanding or authorized 
options, warrants, calls, rights, commitments or any other agreements of any 
character requiring the Company or any stockholder to issue, transfer, sell, 
purchase, redeem or acquire the Shares or any shares of capital stock or any 
securities or rights convertible into, or exchangeable for, or evidencing the 
right to subscribe for, any shares of capital stock of the Company.

     3.   The Stockholder has the full right, power and authority to execute 
and deliver the Merger Agreement and the Ancillary Agreements and to 
consummate the transactions contemplated thereby.  The Company has the 
corporate power and authority to approve, authorize, execute and deliver the 
Merger Agreement and, to the extent it is a party thereto, the Ancillary 
Agreements, and to consummate the transactions contemplated thereby.

     4.   The execution and delivery by the Company of the Merger Agreement 
and the Ancillary Agreements to which it is a party, and the consummation by 
the Company of the transactions contemplated thereby, have been duly and 
validly authorized by the Board of Directors of the Company and by the 
stockholders of the Company and no other corporate proceedings on the part of 
the Company are necessary to authorize the Merger Agreement or the Ancillary 
Agreements or to 

<PAGE>

consummate the transactions contemplated thereby.  Each of the Merger 
Agreement and the Ancillary Agreements has been duly executed and delivered 
by the Company and the Stockholder and is a valid and binding obligation of 
the Company and the Stockholder, enforceable against the Company and the 
Stockholder in accordance with its terms, except that enforcement thereof may 
be limited by (i) bankruptcy, insolvency, reorganization, moratorium, 
fraudulent conveyance or other similar laws now or hereafter in effect 
relating to or affecting creditors' rights generally and (ii) general 
principles of equity (regardless of whether enforceability is considered in 
proceeding in equity or at law).

     5.   The execution and delivery by the Company of the Merger Agreement 
and the Ancillary Agreements to which it is a party and the performance by 
the Company of all of its obligations under each such document in accordance 
with its terms, do not (i) conflict with its Articles of Incorporation or 
By-Laws, (ii) constitute a violation of or default under any Listed Agreement 
set forth on Schedule 5.1(l) of the Merger Agreement (each, an "Applicable 
Contract") or (iii) require the creation or imposition of any security 
interest or lien upon any of the property of the Company pursuant to its 
Articles of Incorporation, By-Laws or any Applicable Contract.

     6.   To the best knowledge of Counsel, there are no proceedings pending 
or threatened against or affecting the Company or the Stockholder in any 
court or before any governmental authority or arbitration board or tribunal 
which are likely to (i) prevent or declare unlawful the transactions 
contemplated by the Merger Agreement or cuase such transactions to be 
rescinded or (ii) have a Material Adverse Effect with respect to the Company.

     7.   All necessary approvals, consents and other actions by, and notices 
to and filings with, governmental authroities in connection with the transfer 
to Parent of the Shares as eontemplated by the Merger Agreement have been 
obtained or acomplished.

                                       2

                               FORM OF ESCROW AGREEMENT


     THIS ESCROW AGREEMENT, dated as of ______________________, 1998 (this 
"Escrow Agreement"), is by and among Ecolab Inc., a Delaware corporation 
("Parent"), GCS Service, Inc., a Delaware corporation (the "Company"), Wesley 
B. Tyler (referred to herein as the "Stockholder Representative"), and 
Norwest Bank Minnesota, National Association, as escrow agent (the "Escrow 
Agent").

     A.   Parent, the Company, the Stockholder Representative and GCS 
Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of 
Parent, entered into an Agreement and Plan of Merger dated as of 
_________________, 1998 (the "Merger Agreement"), which sets forth the terms 
and conditions of the Merger (as defined in the Merger Agreement).

     B.   Section 9.6 of the Merger Agreement provides for the placement in 
escrow, pursuant to the terms of this Escrow Agreement, of an aggregate 
amount equal to the sum of ten percent (10%) of the Merger Consideration (as 
defined in the Merger Agreement) initially paid to each shareholder of the 
Company, pursuant to Section 4.1 of the Merger Agreement, in order to provide 
a non-exclusive source of funds which may be payable to Parent under the 
Merger Agreement, including without limitation the obligations under Sections 
4.2, 9.1 and 9.2 thereof (all Parent Shares held under this Escrow Agreement 
are referred to herein as the "Escrow Shares").

     C.   The Company and the stockholders of the Company have appointed 
Wesley B. Tyler as their agent and representative for, among other things, 
all purposes related to this Escrow Agreement.  [Add power of substitution].

     D.   The terms used herein with an initial capital letter, unless 
otherwise defined herein, shall have the same meaning in this Escrow 
Agreement as such terms have under the Merger Agreement.

     In consideration of the representations, warranties, covenants and 
agreements contained herein, the receipt and sufficiency of which are hereby 
acknowledged, and intending to be legally bound hereby, the parties hereto 
agree as follows:

<PAGE>

          1.   ESCROW DEPOSIT.  The Stockholder Representative, on behalf of 
the Company and the stockholders of the Company, in consideration of the 
transactions contemplated by the Merger Agreement, in order to induce Parent 
to consummate the transactions contemplated by the Merger Agreement, and in 
order to secure the obligations of the Company and the stockholders of the 
Company pursuant to the Merger Agreement, hereby agree to the deposit by 
Parent into escrow of the Escrow Shares pursuant to this Escrow Agreement.  
In furtherance thereof, the Stockholder Representative hereby authorizes 
Parent to deposit the Escrow Shares with the Escrow Agent at the Closing, in 
the name of the Escrow Agent, to be held as nominee and for the benefit of 
the stockholders of the Company.  As so deposited, the Escrow Shares, 
together with any distributions, property or other rights distributed 
(including, without limitation, upon a stock split, stock dividend or other 
recapitalization of Parent), other than Parent's regular quarterly cash 
dividends which shall be distributed on a current basis, with respect to or 
in exchange for, or otherwise attaching to, the Escrow Shares, are herein 
collectively referred to as the "Escrow Fund." Each of the Company, Parent 
and the Stockholder Representative acknowledge and agree that the Escrow 
Shares will not be issued in the name of any stockholder of the Company until 
released to such stockholder pursuant to this Escrow and that no stockholder 
of the Company will be entitled to sell, transfer, encumber or otherwise 
dispose of any Escrow Shares or other property constituting a part of the 
Escrow Fund deposited hereunder or any interest therein unless and until such 
Escrow Shares or other property constituting a part of the Escrow Fund are 
delivered to the stockholders of the Company pursuant to the terms of this 
Escrow Agreement, and any purported transfer in violation of the foregoing 
restriction shall be null, void and of no force or effect.  The Escrow Agent 
will hold and administer the Escrow Fund in accordance with the provisions of 
this Escrow Agreement.

          2.   AGENT FOR THE COMPANY AND THE STOCKHOLDERS OF THE COMPANY.  
The Stockholder Representative shall be the agent for the Company and the 
stockholders of the Company under this Escrow Agreement and shall have the 
sole power and authority to act on their behalf for the purposes of this 
Escrow Agreement.

          3.   AUTHORITY OF  ESCROW AGENT.  The Stockholder Representative, 
on behalf of the Company and the stockholders of the Company, by execution 
and delivery of this Escrow Agreement, constitutes and appoints the Escrow 
Agent as the true and lawful agent and attorney-in-fact to hold in its name 
(or its nominee's name), and to assign and transfer the Escrow Shares and the 
Escrow Fund for each of the stockholders of the Company and in the place and 
stead of each of them, as fully and to all the same extent as each of them 
could do in its own behalf, as shall from time to time

                                       2
<PAGE>

be required in accordance with the provisions of this Escrow Agreement.  In 
furtherance of the foregoing and not in limitation thereof, the Escrow Agent 
is specifically authorized to forward any certificates representing any 
Escrow Shares or any other property constituting a part of the Escrow Fund to 
Parent's transfer agent for purposes of having any such shares or other 
property cancelled and returned to Parent as may be necessary to accomplish 
the intent and purposes of this Escrow Agreement.  Such authority of the 
Escrow Agent shall not be affected by the subsequent bankruptcy, insolvency, 
death, disability or incompetence of any of the stockholders of the Company.

          4.   OWNERSHIP OF ESCROW FUND.  Unless and until assigned, 
transferred and delivered to Parent in accordance with the provisions hereof, 
the Escrow Shares and any other property constituting a part of the Escrow 
Fund deposited with the Escrow Agent shall be held in trust for each 
stockholder of the Company as designated by the Stockholder Representative, 
in proportion to the number of shares held in the Escrow Fund for the benefit 
of each stockholder of the Company, as set forth on Exhibit D hereto, such 
amount being adjusted from time to time pursuant to the Merger Agreement, 
(such amount being referred to herein, as with respect to each holder, its 
"Pro Rata Share").  All distributions, property and other rights distributed 
(including, without limitation, upon a stock split, stock dividend or other 
recapitalization of Parent), except for Parent's regular quarterly cash 
dividends which shall be distributed on a current basis,  with respect to or 
in exchange for, or otherwise attaching to, the Escrow Shares shall attach to 
and run with, or be exchanged for, as the case may be, the Escrow Shares, 
shall become a part of the Escrow Fund and shall be delivered to stockholders 
of the Company as designated by the Stockholder Representative based upon 
each stockholder's Pro Rata Share or assigned, transferred and delivered to 
Parent, as the case may be, only as, if and when the Escrow Shares related to 
such distributions, property and other rights are to be delivered to 
stockholders of the Company based upon Pro Rata Share or to be assigned, 
transferred and delivered to Parent, as the case may be, in accordance with 
the terms of this Escrow Agreement.  [Add provision that Escrow Agent will
pass on vote to the stockholders of the Company]

          5.   PURPOSE OF ESCROW FUND.  The Escrow Fund shall be held by the 
Escrow Agent as a non-exclusive source of funds for the satisfaction of the 
obligations of the Company and the stockholders of the Company with respect 
to the purchase price adjustments provided for in Section 4.2 of the Merger 
Agreement and the indemnification provisions of Article 9 of the Merger 
Agreement.  The parties hereto acknowledge that (i) resort to the Escrow Fund 
is not the sole or exclusive remedy of Parent to satisfy the obligations of 
the stockholders of the Company under the Merger Agreement; (ii)

                                       3
<PAGE>

Parent may pursue any other remedies available to it, whether under the 
Merger Agreement or otherwise, or at law or in equity and (iii) Parent shall 
not be required to pursue or exhaust any other remedies available to it prior 
to pursuing its rights under this Escrow Agreement.

          6.   DISTRIBUTION OF ESCROW FUND.  Subject to the provisions of the 
last paragraph of this Section 6, and Section 10 hereof, the Escrow Fund will 
be delivered to the stockholders of the Company as designated by the 
Stockholder Representative or assigned, transferred and delivered to Parent 
as follows:

               (a)  Following the determination of the Adjusted Net Book 
Value pursuant to Section 4.2 of the Merger Agreement, in the event that the 
Merger Consideration is to be decreased pursuant thereto, the Stockholder 
Representative agrees that Parent shall be authorized to direct the Escrow 
Agent to assign, transfer and deliver to Parent the number of Escrow Shares 
(and the distributions, property or other rights related to such Escrow 
Shares, whether upon a stock split, stock dividend, recapitalization or 
otherwise, as provided herein, except for Parent's regular quarterly cash 
dividends which shall be paid on a current basis) in an amount equal to (A) 
the difference between (1) the Net Worth of the Company set forth on the 
Estimated Closing Balance Sheet and (2) the Adjusted Net Book Value divided 
by (B) the Average Stock Price.  The Stockholder Representative and the 
Escrow Agent shall be jointly and severally obligated to deliver such Escrow 
Shares to the Parent, within two (2) business days following determination of 
the Adjusted Closing Date Balance Sheet.

               (b)  In the event that Parent shall pursue certain claims 
described in Section 6.14 of the Merger Agreement, upon final judgment or 
settlement of any such claims and distribution by Parent of any portion of 
the cash recovery in favor of Parent under such claims to the Escrow Agent in 
accordance with Section 6.14 of the Merger Agreement (the "Judgment 
Proceeds"), the Escrow Agent shall deliver to each Stockholder of the Company 
a portion of the Judgment Proceeds, if any, as determined in proportion to 
each Stockholder's Pro Rata Share, in accordance with written instructions 
provided by the Stockholder Representative 
[Alternative:  insert description of any settlement entered into prior
to Closing].

               (c)  On ____________, 2000, the two year anniversary of the 
Closing Date, the Escrow Agent will deliver to each of the stockholders of 
the Company its Pro Rata Share, according to written directions provided by 
the Stockholder Representative, of the Escrow Shares  (and the distributions, 
property or other rights related to such Escrow Shares, whether upon a stock 
split, stock dividend, recapitaliza-

                                       4
<PAGE>

tion or otherwise, as provided herein, except for Parent's regular quarterly 
cash dividends which shall be paid on a current basis) remaining in escrow, 
reduced by the number of Escrow Shares equal to the dollar amount of any 
claims then pending against the Escrow Fund, divided by the Fair Market Value.

               (d)  Following resolution of all claims consistent with 
Section 6(c) above, the Escrow Agent will deliver to the Stockholder 
Representative (as defined in the Merger Agreement) a number of Escrow Shares 
equal to the dollar amount of any amounts for which the Stockholder 
Representative may be entitled to reimbursement pursuant to Section 4.2(f) of 
the Merger Agreement.

               (e)  Subject to Sections 6(c) and 6.2(d) above, upon the 
termination of this Escrow Agreement, if there are no other claims or losses 
pending, the balance, if any, of the Escrow Shares (and the distributions, 
property or other rights related to such Escrow Shares, whether upon a stock 
split, stock dividend, recapitalization or otherwise, as provided herein, 
except for Parent's regular quarterly cash dividends which shall be paid on a 
current basis) remaining in escrow under this Escrow Agreement shall be 
distributed in accordance with this Section 6 hereof.

     In the event Escrow Shares are returned to Parent and/or Merger Sub for 
any adjustment to the purchase price pursuant to Section 4.2 of the Merger 
Agreement, such Escrow Shares shall be valued per share, at the Average Stock 
Price.  In the event that any Escrow Shares are returned to Parent and/or 
Merger Sub for the indemnification of any claims pursuant to Article 9 hereof 
or the Stockholders Representatives pursuant to Section 6(d), such Escrow 
Shares shall be valued at the Fair Market Value.  Further, when Escrow Shares 
are returned to Parent and/or Merger Sub the calculation shall be determined 
on a per holder basis based on such stockholder's Pro Rata Share such that 
following such return the number of shares held in the Escrow Fund in trust 
for each such stockholder shall equal a whole number of shares.

          7.   CLAIMS AGAINST ESCROW FUND.  If Parent desires to make a claim 
against the Escrow Fund, Parent shall deliver to the Escrow Agent and to the 
Stockholder Representative a notice setting forth a claim for adjustment or 
indemnification under the Merger Agreement, which notice shall state in 
reasonable detail the basis for and dollar amount of the claim and the number 
of Escrow Shares necessary to discharge such claim in accordance with this 
Escrow Agreement (the "Notice of Claim").  Each Notice of Claim shall be in 
the form of EXHIBIT A attached hereto.  If the Stockholder Representative 
desires to dispute such claim or any part thereof, the Stockholder 
Representative shall deliver to the Escrow Agent and to Parent, within

                                       5
<PAGE>

twenty (20) days after the Notice of Claim has been delivered to the Escrow 
Agent and the Stockholder Representative, a written notice (the "Rebuttal 
Notice") setting forth in reasonable detail the basis for the dispute of such 
claim.  Each Rebuttal Notice shall be in the form of EXHIBIT B attached 
hereto.

     If, upon the expiration of twenty (20) days after the Notice of Claim 
has been delivered to the Escrow Agent and the Stockholder Representative, 
the Escrow Agent shall not have received a Rebuttal Notice from the 
Stockholder Representative, then subject to the last paragraph of Section 6 
the Escrow Agent shall deliver to Parent the number of Escrow Shares (and the 
distributions, property or other rights related to such Escrow Shares as 
provided herein) equal to the dollar amount of the claim provided for in the 
Notice of Claim divided by the Fair Market Value.

     If, prior to the expiration of such 20-day period, the Escrow Agent 
shall receive a Rebuttal Notice, a conflict shall be deemed to have arisen 
between the Notice of Claim and the Rebuttal Notice.  Thereupon, the Escrow 
Agent shall be entitled to refrain from taking any action until the Escrow 
Agent shall be directed otherwise in writing executed by both of Parent and 
the Stockholder Representative or by a court of competent jurisdiction.

          8.   APPOINTMENT, RESIGNATION, REMOVAL AND INDEMNIFICATION OF 
ESCROW AGENT.

               (a)  Parent and the Stockholder Representative hereby appoint 
the Escrow Agent in accordance with and to be governed by the terms and 
conditions set forth in this Escrow Agreement, and the Escrow Agent hereby 
accepts such appointment.

               (b)  The duties and responsibilities of the Escrow Agent shall 
be limited to those expressly set forth herein and the Escrow Agent shall not 
be obligated to recognize any other agreement between any of the parties 
hereto, even though reference thereto may be made herein and whether or not 
the Escrow Agent has knowledge thereof.

               (c)  The Escrow Agent shall not be personally liable for any 
action taken or omitted to be taken hereunder if taken or omitted to be taken 
by the Escrow Agent in good faith or in the exercise by the Escrow Agent of 
its own best judgment.  The Escrow Agent shall also be fully protected in 
relying upon any written

                                       6
<PAGE>

notice, demand, certificate or document that the Escrow Agent in good faith 
believes to be genuine.

               (d)  Provided it acts in good faith, the Escrow Agent shall 
not be responsible for the sufficiency or accuracy of the form, execution, 
validity or genuineness of notices, documents or securities now or hereafter 
deposited or delivered under this Escrow Agreement, or of any endorsement 
thereof, or for any lack of endorsement thereof, or for any description 
therein, nor shall the Escrow Agent be responsible or liable in any respect 
on account of the identity, authority or rights of the persons executing or 
delivering or purporting to execute or deliver this Escrow Agreement or any 
such document, notice, security or endorsement.

               (e)  The Escrow Agent may resign at any time or be removed by 
the mutual consent of Parent and the Stockholder Representative.  No 
resignation or removal of the Escrow Agent and no appointment of a successor 
Escrow Agent, however, shall be effective until the acceptance of appointment 
by the successor Escrow Agent in the manner herein provided. In the event of 
the resignation or removal of the Escrow Agent, Parent and the Stockholder 
Representative shall agree upon a successor Escrow Agent.  Any successor 
Escrow Agent shall execute and deliver to the predecessor Escrow Agent, 
Parent and the Stockholder Representative an instrument accepting such 
appointment and the transfer of the Escrow Fund and agreeing to the terms of 
this Escrow Agreement, and thereupon such successor Escrow Agent shall, 
without further act, become vested with all the estates, properties, rights, 
powers and duties of the predecessor Escrow Agent as if originally named 
herein.  In the event Parent and the Stockholder Representative are unable to 
agree upon a successor Escrow Agent within twenty (20) days of the creation 
of the vacancy, Parent and the Stockholder Representative shall submit the 
dispute for resolution to a court of competent jurisdiction.

               (f)  Parent and the Stockholder Representative hereby 
indemnify and hold harmless the Escrow Agent from and against any and all 
loss, liability, cost, damage and expense, including, without limitation, 
reasonable counsel fees, which the Escrow Agent may suffer or incur by reason 
of any action, claim or proceeding brought against the Escrow Agent arising 
out of or relating in any way to this Escrow Agreement or any transaction to 
which this Escrow Agreement relates unless such action, claim or proceeding 
is the result of the bad faith conduct, willful misconduct or gross 
negligence of the Escrow Agent.  The Escrow Agent may consult counsel in 
respect of any question arising under this Agreement and the Escrow Agent 

                                       7
<PAGE>

                                  [EXHIBIT D]

                  FORM OF OPINION OF INSIDE COUNSEL TO PARENT


     Based upon and subject to the foregoing and to the qualifications and 
limitations set forth in this letter, we are of the opinion that:

     1.  Parent is a corporation validly existing and in good standing under 
the laws of the State of Delaware.  Parent has the corporate power and 
corporate authority to carry on its businesses as it is now being conducted.

     2.  Parent has the corporate power and corporate authority to execute 
and deliver the Merger Agreement and the Ancillary Agreements, and to perform 
any and all obligations contemplated thereby.

     3.  The execution and delivery by parent of the Merger Agreement and the 
Ancillary Agreements and the consummation by Parent of the transactions 
contemplated thereby have been authorized by all requisite corporate action 
on the part of Parent.  Each of the Merger Agreement and the Ancillary 
Agreements has been duly executed and delivered by Parent and is a valid and 
binding obligation of Parent, enforceable against Parent in accordance with 
its terms, except that enforcement thereof may be limited by (i) bankruptcy, 
insolvency, reorganization, moratorium, fraudulent conveyance or other 
similar laws now or hereafter in effect relating to or affecting creditors' 
rights generally and (ii) general principles of equity (regardless of whether 
enforceability is considered in proceeding in equity or at law).

     4.  The execution and delivery by Parent of the Merger Agreement and the 
Ancillary Agreements and the performance by Parent of all of its obligations 
under each such document in accordance with its terms, do not (i) conflict 
with its Certificate of Incorporation or By-Laws; (ii) constitute a violation 
of or default under any contract listed on Exhibit A hereto (each, an 
"Applicable Contract") or (iii) require the creation or imposition of any 
security interest or lien upon any of the property of Parent pursuant to its 
Certificate of Incorporation, By-Laws or any Applicable Contract.

     5.  All of the Parent Shares will be, when issued in accordance with the 
Merger Agreement, duly authorized, validly issued, fully paid and 
nonassessable.

          262 APPRAISAL RIGHTS. (a)  Any stockholder of a corporation of this
State who holds shares of stock on the date of the making of a demand pursuant
to subSection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
ha otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to Section 228 of this title shall be entitled to an appraisal by the
Court of Chancery of the fair value of the stockholder's shares of stock under
the circumstances described in subsections (b) and (c) of this section.  As used
in this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.

               (b)  Appraisal rights shall be available for the shares of any
class or series of stock of a constituent corporation in a merger or
consolidation to be effected pursuant to Section 251 (other than a merger
effected pursuant to Section 251 (g) of this title), Section 252, Section 254,
Section 257, Section 258, Section 263 or Section 264 of this title:

                              (1)  Provided, however, that no appraisal
     rights under this section shall be available for the shares of any
     class or series of stock, which stock, or depository receipts in
     respect thereof, at the record date fixed to determine the
     stockholders entitled to receive notice of and to vote at the meeting
     of stockholders to act upon the agreement of merger or consolidation,
     were either (i) listed on a national securities exchange or designated
     as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii)
     held of record by more than 2,000 holders; and further provided that
     no appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not
     require for its approval the vote of the stockholders of the surviving
     corporation as provided m subsection (f) of Section 251 of this title.

                              (2)  Notwithstanding paragraph (1) of this
     subsection, appraisal rights under this section shall be 


<PAGE>

     available for the shares of any class or series of stock of a constituent
     corporation if the holders thereof are required by the terms of an
     agreement of merger or consolidation pursuant to Sections 251, 252,
     254, 257, 258, 263 and 264 of this title to accept for such stock
     anything except:

                         (i)  Shares of stock of the corporation surviving
     or resulting from such merger or consolidation, or depository receipts
     in respect thereof;

                         (ii) Shares of stock of any other corporation, or
     depository receipts in respect thereof, which shares of stock (or
     depository receipts in respect thereof) or depository receipts at the
     effective date of the merger or consolidation will be either listed on
     a national securities exchange or designated as a national market
     system security on an interdealer quotation system by the National
     Association of Securities Dealers, Inc. or held of record by more than
     2,000 holders;

                         (iii)     Cash in lieu of fractional shares or
     fractional depository receipts described in the foregoing
     subparagraphs a. and b. of this paragraph; or

                         (iv) Any combination of the shares of stock,
     depository receipts and cash in lieu of fractional shares or
     fractional depository receipts described in the foregoing
     subparagraphs a., b. and c. of this paragraph.

                              (3)  In the event all of the stock of a
     subsidiary Delaware corporation party to a merger effected under
     Section 253 of this title is not owned by the parent corporation
     immediately prior to the merger, appraisal rights shall be available
     for the shares of the subsidiary Delaware corporation.

               (c)  Any corporation may provide in its certificate of
incorporation that appraisal rights under this section shall be available for
the shares of any class or series of Its stock as a result of an amendment to
its certificate of incorporation, any merger or consolidation in which the
corporation is a constituent corporation or the sale of all or substantially all
of the assets of the corporation.  If 


                                       2

<PAGE>


the certificate of incorporation contains such a provision, the procedures of 
this section, including those set forth in subsections (d) and (e) of this 
section, shall apply as nearly as is practicable.

               (d)  Appraisal rights shall be perfected as follows:

                              (1)  If a proposed merger or consolidation
     for which appraisal rights are provided under this section is to be
     submitted for approval at a meeting of stockholders, the corporation,
     not less than 20 days prior to the meeting, shall notify each of its
     stockholders who was such on the record date for such meeting with
     respect to shares for which appraisal rights are available pursuant to
     subsections (b) or (c) hereof that appraisal rights are available for
     any or all of the shares of the constituent corporations, and shall
     include m such notice a copy of this section.  Each stockholder
     electing to demand the appraisal of his shares shall deliver to the
     corporation, before the taking of the vote on the merger or
     consolidation, a written demand for appraisal of his shares.  Such
     demand will be sufficient if it reasonably informs the corporation of
     the identity of the stockholder and chat the stockholder intends
     thereby to demand the appraisal of his shares.  A proxy or vote
     against the merger or consolidation shall not constitute such a
     demand.  A stockholder electing to take such action must do so by a
     separate written demand as herein provided.  Within 10 days after the
     effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each
     constituent corporation who has complied with this subsection and has
     not voted in favor of or consented to the merger or consolidation of
     the date that the merger or consolidation has become effective; or

                              (2)  If the merger or consolidation was
     approved pursuant to Section 228 or Section 253 of this title, each
     constituent corporation, either before the effective date of the
     merger or consolidation or within ten days thereafter shall notify
     each of the holders of any class or series of stock of such
     constituent corporation who are entitled to appraisal rights of the
     approval of the merger or consolidation and chat appraisal rights are
     available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy
     of this section; provided that, 


                                          3

<PAGE>

     if the notice is given on or after the effective date of the merger or 
     consolidation, such notice shall be given by the surviving or resulting
     corporation to all such holders of any class or series of stock of a 
     constituent corporation that are entitled to appraisal rights.  Such 
     notice may, and, if given on or after the effective date of the merger
     or consolidation, shall, also notify such stockholders of the effective
     date of the merger or consolidation.   Any stockholder entitled to 
     appraisal rights may, within 20 days after the date of mailing of such
     notice, demand in writing from the surviving or resulting corporation the
     appraisal of such holder's shares.  Such demand will be sufficient if it 
     reasonably informs the corporation of the identity of the stockholder and
     that the stockholder intends thereby to demand the appraisal of such
     holder's shares.  If such notice did not notify stockholders of the
     effective date of the merger or consolidation, either (i)  each such 
     constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the
     holders of any class or series of stock of such constituent
     corporation that are entitled to appraisal rights of the effective
     date of the merger or consolidation or (ii) the surviving or resulting
     corporation shall send such a second notice to all such holders on or
     within l0 days after such effective date, provided, however, that if
     such second notice is sent more than 20 days following the sending of
     the first notice, such second notice need only be sent to each
     stockholder who is entitled to appraisal rights and who has demanded
     appraisal of such holder's shares in accordance with this subsection. 
     An affidavit of the secretary or assistant secretary or of the
     transfer agent of the corporation that is required to give either
     notice chat such notice has been given shall, in the absence of fraud,
     be prima facie evidence of the facts stated therein.  For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall
     be not more than 10 days prior to the date the notice is given,
     provided, that if the notice is given on or after the effective date
     of the merger or consolidation, the record date shall be such
     effective date.  If no record date is fixed and the notice is given
     prior to the effective date, the record date shall be the close of
     business on the day next preceding the day on which the notice is
     given.

               (e)  Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.  
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation.  Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
of the merger or consolidation and with respect to which demands for appraisal
have been received and the aggregate number of holders of such shares.  Such
written statement shall be mailed to the stockholder within l0 days after his
written request for such a statement is received by the surviving or resulting
corporation or within 10 days after expiration of the period for delivery of
demands for appraisal under subsection (d) hereof, whichever is later.

               (f)  Upon the filing of any such petition by a stockholder,
service of a copy thereof shall be made upon the surviving or resulting
corporation, which shall within 20 days after such service file in the office of
the Register in Chancery in which the petition was filed a duly verified list
containing the names and addresses of all stockholders who have demanded payment
for their shares and with whom agreements as to the value of their shares have
not been reached by the surviving or resulting corporation.  If the petition
shall be filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list.  The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated.  Such notice shall also be given by l or more publications at
least l week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable.   The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

               (g)  At the hearing on such petition, the Court shall determine
the stockholders who have complied with this section and who have 


                                      5

<PAGE>

become entitled to appraisal rights.  The Court may require the stockholders 
who have demanded an appraisal for their shares and who hold stock 
represented by certificates to submit their certificates of stock to the 
Register in Chancery for notation thereon of the pendency of the appraisal 
proceedings; and if any stockholder fails to comply with such direction, the 
Court may dismiss the proceedings as to such stockholder.

               (h)  After determining the stockholders entitled to an appraisal,
the Court shall appraise the shares, determining their fair value exclusive of
any element of value arising from the accomplishment or expectation of the
merger or consolidation, together with a fair rate of interest, if any, to be
paid upon the amount determined to be the fair value.  In determining such fair
value, the Court shall take into account all relevant factors.  In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding. 
Upon application by the surviving or resulting corporation or by any stockholder
entitled to participate in the appraisal proceeding, the Court may, in its
discretion, permit discovery or other pretrial proceedings and may proceed to
trial upon the appraisal prior to the final determination of the stockholder
entitled to an appraisal.   Any stockholder whose name appears on the list filed
by the surviving or resulting corporation pursuant to subsection (f) of this
section and who has submitted his certificates of stock to the Register in
Chancery, if such is required, may participate fully in all proceedings until it
is finally determined that he is not entitled to appraisal rights under this
section.  

               (i)  The Court shall direct the payment of the fair value of the
shares, together with interest, if any, by the surviving or resulting
corporation to the stockholders entitled thereto.   Interest may be simple or
compound, as the Court may direct.  Payment shall be so made to each such
stockholder, in the case of holders of uncertificated stock forthwith, and the
case of holders of shares represented by certificates upon the surrender to the
corporation of the certificates representing such stock.  The Court's decree may
be enforced as other decrees in the Court of Chancery may be enforced, whether
such surviving or resulting corporation be a corporation of this State or of any
state.

               (j)  The costs of the proceeding may be determined by the Court
and taxed upon the parties as the Court deems equitable in the circumstances. 
Upon application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, 

                                   6

<PAGE>


including, without limitation, reasonable attorney's fees, and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

               (k)  From and after the effective date of the merger or
consolidation, no stockholder who has demanded his appraisal rights as provided
in subsection (d) of this section shall be entitled to vote such stock for any
purpose or to receive payment of dividends or other distributions on the stock
(except dividends or other distributions payable to stockholders of record at a
date which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal of
his demand for an appraisal and an acceptance of the merger or consolidation,
either within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease.   Nothwithstanding the foregoing, no appraisal proceeding in the
Court of Chancery shall be dismissed to any stockholder without approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

                              (1)  The shares of the surviving or resulting
     corporation to which the shares of such objecting stockholders would
     have been converted had they assented to the merger or consolidation
     shall have the status of authorized and unissued shares of the
     surviving or resulting corporation.   (Last amended by Ch. 120, L.
     '97, eff. 7-1-97.)

Board of Directors
GCS Service, Inc.
83 Wooster Heights Road
Danbury, CT 06810

Gentlemen:

GCS Service, Inc. (the "Company") and Ecolab, Inc. (the "Acquirer") have 
entered into an Agreement and Plan of Merger Among Ecolab, Inc., GCS 
Acquisition Corporation, GCS Service, Inc. and Wesley B. Tyler, dated the 
date hereof, (the "Agreement").  Pursuant to the Agreement, all the Company's 
outstanding common stock, $.01 per share par value per share, will be 
acquired by the Acquirer for $26,363,671 in shares of the Acquirer's Common 
Stock ("Ecolab Stock") with similar terms and conditions to its existing 
Common Stock, together with the associated rights to purchase shares of 
Series A Junior Participating Preferred Stock of the Acquirer issued pursuant 
to the Rights Agreement dated February 24, 1996. 

You have asked us whether, in our opinion, the proposed consideration to be 
received by the holders of the Company's outstanding shares, taken as a 
whole, is fair, to such shareholders from a financial point of view. Our 
opinion does not address the allocation of the consideration among the 
shareholders of the Company, whether pursuant to the Agreement, the Company's 
Certificate of Incorporation or otherwise.

In arriving at the opinion set forth below, we have, among other things:

1.   Reviewed the Company's financial statements and related financial
     information for the four fiscal years ended September 30, 1997, and the
     related unaudited financial information for the quarterly period ended
     March 31, 1998;

2.   Reviewed the Acquirer's Annual Report, Form 10-K for the fiscal year ended
     December 31, 1997 and the Form 10-Q and the related unaudited financial
     information for the quarterly period ended March 31, 1998;

3.   Reviewed certain information, including financial forecasts, relating to
     the business, earnings, cash flow, assets and prospects of the Company,
     furnished to us by the Company;

4.   Conducted discussions with members of senior management and the Board of
     Directors of the Company concerning its business and prospects;

5.   Compared the Company's contemplated transaction with that of certain other
     transactions which we deemed to be reasonably similar;

Board of Directors
Page 2

6.   Reviewed the Agreement dated as of May 12, 1998;

7.   Reviewed the draft of Wesley B. Tyler's Employment contract appended to the
     Agreement dated May 12, 1998 and the draft of the Stay and Pay Agreements
     of Sam Mazzilli and James Rowland;

8.   Reviewed the Restated Certificate of Incorporation of Ecolab, Inc. dated
     October 22, 1997;

9.   Reviewed such other financial information and analysis and performed such
     other investigations and took into account such other matters as we deemed
     appropriate, including our assessment of general economic, market, monetary
     and other conditions as they exist on the date hereof and further 
     including our review certain financial information provided by the 
     Company's independent auditors.

In preparing our opinion, we have relied on and assumed the accuracy and 
completeness of all information supplied or otherwise made available to us by 
the Company.  We have not independently verified any such information or 
assumptions, including financial forecasts, or undertaken (and have assumed 
no responsibility to undertake), and have not been provided with, an 
independent evaluation or appraisal of the assets or liabilities (contingent 
or otherwise) of the Company and the Acquirer and have assumed that all 
assets or liabilities (contingent or otherwise, known or unknown) of the 
Company and the Acquirer are as set forth in their respective consolidated 
financial statements. With respect to the financial forecasts furnished by 
the Company, we have assumed that they have been reasonably prepared and 
reflect the best currently available estimates and judgment of the Company's 
management as to the expected future financial performance of the Company. 
Our opinion is based upon regulatory, general economic, market and monetary 
conditions existing on the date hereof.

Our opinion set forth below is directed to the Board of Directors of the 
Company and does not constitute a recommendation to any shareholder of the 
Company with respect to the approval of the transactions contemplated by the 
Agreement.  Our opinion does not address the relative merits of the 
transaction and any other transactions or business strategies discussed by 
the Board of Directors of the Company as alternatives to the transaction or 
the decision of the Board of Directors of the Company to proceed with the 
transaction.  This letter is for the information of the Board of Directors of 
the Company only in connection with its consideration of the Agreement and is 
not to be reproduced, summarized, quoted or referred to, in whole or in part, 
except in the proxy statement, S-4, and other document prepared in connection 
with the transactions contemplated by the Agreement, nor shall this letter be 
used for any other purposes or publicly disclosed except as provided, without 
our prior written consent.

We have acted as financial advisor to the Board of Directors of the Company 
in connection with the transaction contemplated by the Agreement and will 
receive a fee for our services.  None of Carter Capital Corporation's 
employees have any past, present, prospective, direct, or indirect interest 
in the stock of the Company.  Further, the compensation for this opinion is 
neither based upon nor contingent upon the conclusion reported.

On the basis of, and subject to the foregoing, we are of the opinion that the 
proposed stock consideration to be received by the Company's stockholders, 
taken as a whole, is fair to such stockholders from a financial point of view.

Very Truly Yours,

CARTER CAPITAL CORPORATION

                                     PART II

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

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

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

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

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

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

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

         Ecolab has entered into indemnification agreements with each of its 
directors (the "Indemnification Agreements"). The Indemnification Agreements 
provide for the prompt indemnification "to the fullest extent permitted by 
law" and for the prompt advancement of expenses, including attorneys' fees 
and other costs, expenses and obligations paid or incurred in connection with 
investigating, defending, being a witness or participating in (including on 
appeal) any threatened, pending or completed action, suit or proceeding 
related to the fact that such director is or was a director, officer, 
employee, trustee, agent or fiduciary of Ecolab or is


<PAGE>


or was serving at the request of Ecolab as a director, officer, employee, 
trustee, agent or fiduciary of another corporation, partnership, joint 
venture, employee benefit plan trust or other enterprise, or by reason of 
anything done or not done by a director in any such capacity. The 
Indemnification Agreements further provide that Ecolab has the burden of 
proving that a director is not entitled to indemnification in any particular 
case.

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

ITEM 22.  UNDERTAKINGS

      The undersigned Registrant hereby undertakes:

         1.       That, for purposes of determining any liability under the
                  Securities Act of 1933, each filing of the Registrant's annual
                  report pursuant to Section 13(a) or 15(d) of the Securities
                  Exchange Act of 1934 that is incorporated by reference in the
                  Registration Statement shall be deemed to be a new
                  Registration Statement relating to the securities offered
                  therein, and the offering of such securities at that time
                  shall be deemed to be the initial bona fide offering thereof.

         2.       That, prior to any public reoffering of the securities
                  registered hereunder through use of a Proxy State
                  ment/Prospectus which is a part of this Registration
                  Statement, by any person or party who is deemed to be an
                  underwriter within the meaning of Rule 145(c), the issuer

         3.       That every Proxy Statement/Prospectus (i) that is filed
                  pursuant to the immediately preceding paragraph or (ii) that
                  purports to meet the requirements of Section 10(a)(3) of the
                  Securities Act of 1933 and is used in connection with an
                  offering of securities subject to Rule 415, will be filed as a
                  part of an amendment to the Registration Statement and will
                  not be used until such amendment is effective, and that, for
                  purposes of determining any liability under the Securities Act
                  of 1933, each such post-effective amendment shall be deemed to
                  be a new Registration Statement relating to the securities
                  offered therein, and the offering of such securities at that
                  time shall be deemed to be the initial bona fide offering
                  thereof.

         4.       Insofar as indemnification for liabilities arising under the
                  Securities Act of 1933 may be permitted to directors, officers
                  and controlling persons of the Registrant pursuant to the
                  provisions described under Item 20 above or otherwise, the
                  Registrant has been advised that in the opinion of the
                  Securities and Exchange Commission such indemnification is
                  against public policy as expressed in the Securities Act of
                  1933 and is, therefore, unenforceable.  In the event that a
                  claim for indemnification against such liabilities (other than
                  the payment by the Registrant of expenses incurred or paid by
                  a director, officer or controlling person of the Registrant
                  in the successful defense of any action, suit or proceeding)
                  is asserted by such director, officer or controlling person
                  in connection with the securities being registered, the
                  Registrant will, unless in the opinion of its counsel the
                  matter has been settled by controlling precedent, submit to
                  a court of appropriate jurisdiction the question whether such
                  indemnification by it is against public policy as expressed
                  in the Act and will be governed by the final adjudication of
                  such issue.

         5.       To respond to requests for information that is incorporated by
                  reference into the Proxy Statement/Prospectus pursuant to Item
                  4, 10(b), 11, or 13 of this form, within one business day of
                  receipt of such request, and to send the incorporated
                  documents by first class mail or other equally prompt means.
                  This includes information contained in documents filed
                  subsequent to the effective date of the Registration Statement
                  through the date of responding to the request.

         6.       To supply by means of a post-effective amendment all
                  information concerning a transaction, and the company being
                  acquired involved therein, that was not the subject of and
                  included in the Registration Statement when it became
                  effective.
