     Except for the steps or actions taken pursuant to prior written consent

conduct the Business consistent with historical practices, and during that 
period Seller shall:

     (a)   conduct the Business only in the normal course;

     (b)   not transfer any of the assets or properties of the Business 
except in the normal course;

     (c)   except for customary agreements in the nature of pre-rights

matters, not enter into any patent, know-how, trademark or trade name licenses,
purchase orders for raw materials, packaging and/or finished goods, or any other
leases, licenses, contracts or other commitments relating exclusively to the
Business, unless each such lease, license, contract, purchase order or
commitment is disclosed to and approved by Buyer - the foregoing notwithstanding
Seller may enter into new sales contracts in the ordinary course of business.

     (d)   continue to meet the contractual obligations of, and to pay
obligations relating to, the Business as they mature in the normal course; and

defense of any litigation, hearing, regulatory proceeding, or investigation or
other similar matter relating to the Business, they will make available during
normal business hours, but without unreasonably disrupting their respective

appropriate secrecy commitments to protect such information.

assets of, or the majority of the voting interest in, another Person 
(hereinafter a 'Target Business') if the revenue derived by the Target 
Business from the Buyer Competitive Business in the fiscal year preceding 
such acquisition constituted less than twenty percent (20%) of the aggregate 
net sales of the Target Business.

     (c)   In the event Seller or an Affiliate acquires a Buyer Competitive
Business under the circumstances described in Section 6.5(b)(iii) above, and if
the sales of the Buyer Competitive Business contained within the Target Business
exceed five million U.S. dollars (U.S. $5,000,000.00) on an annual basis,
Seller or such Affiliate shall thereafter divest such Buyer Competitive Business
with twenty four (24) months from the date of purchase of the Buyer Competitive

sale, or such other manner of divestiture as Seller, in its sole and
non-reviewable discretion, deems appropriate.

claim or liability arising from any dispute(s) between Ecolab Inc. and Seller

Ecolab Inc. agreements or any subsequent post-termination notice claim that the
Ecolab Inc. agreements will not terminate effective September 30, 1999.

     (c)   Buyer shall indemnify Seller and hold it harmless against any loss,
claim, or liability arising from any dispute relating to Ecolab Inc. which arise

                INDEMNIFICATIONS: PROCEDURES FOR CLAIMS: ARBITRATION


8.1   Indemnification by Seller.

      (a)   Seller hereby assumes, undertakes, and will pay or otherwise 
discharge, and will indemnify and hold Buyer harmless against:

            (i)   all claims, losses, liabilities, damages, costs and expenses,
                  including, without limitation, reasonable fees and expenses of
                  attorneys incurred in the investigation, prosecution or
                  defense (at trial and appellate levels and otherwise) of any
                  claim or action brought by or against Buyer (hereinafter
                  collectively called 'Losses') arising out of, based upon, or
                  alleging any matter involving an Excluded Liability or breach
                  of a representation and warranty or covenant made by Seller
                  herein, and;

            (ii)  all costs and expenses of Buyer (including, without
                  limitation, reasonable fees and expenses of attorneys)


                                       24


                  incurred in connection with the enforcement of any rights of
                  Buyer under the indemnity provided in this Section.

(b) Seller's liability under Section 8.1(a) with respect to Losses arising out
of an Excluded Liability described in Section 1.11(c) or breach of a
representation and warranty or covenant by Seller shall not arise unless Buyer's
Losses, in the aggregate, exceed two hundred thousand ($200,000.00) dollars,
except that the foregoing limitation shall not apply to any claims for
indemnification arising with respect to broker or finder's fee under Section 5.4

      (c)   Promptly after receipt by Buyer of notice of the assertion of any 
claim or the commencement of any action in respect of which indemnity or 
reimbursement may be sought against Seller hereunder (for purposes of this
Section, an 'Assertion'), Buyer shall notify Seller in writing of the Assertion,
but the failure to so notify Seller shall not relieve Seller of any liability it
may have to Buyer.  If the matter involves litigation or governmental
investigation (including a tax audit), Seller shall be entitled to participate
in and, to the extent Seller elects by written notice to Buyer within thirty
(30) days after receipt by Seller of notice to such Assertion, to assume the
defense of such Assertion, at its own expense, with counsel chosen by it which
shall be reasonably satisfactory to Buyer.  Notwithstanding that Seller shall
have elected by such written notice to assume the defense of any Assertion,
Buyer shall have the right to participate in the investigation and defense


                                       25


thereof, with separate counsel chosen by Buyer, but in such event the fees 
and expenses of such separate counsel shall be paid by Buyer.

      (d)   Notwithstanding anything in this Section to the contrary,

            (i)   Seller shall have no obligation with respect to an Assertion
                  if, in connection therewith, Buyer, without the written
                  consent of Seller, shall settle or compromise any action or
                  consent to the entry of any judgment, and

            (ii)  Seller shall not, without the written consent of Buyer, (A)
                  settle or compromise any action or consent to the entry of any
                  judgment which does not include as an unconditional term
                  thereof the delivery by the claimant or plaintiff to Buyer of
                  a duly executed written release of Buyer from all liability in
                  respect of such action, which release shall be satisfactory in
                  form and substance to counsel for Buyer, or (B) settle or
                  compromise any action in any manner that, in the sole judgment
                  of Buyer or their counsel, may materially and adversely affect
                  Buyer other than as a result of money damages or other money
                  payments.

      (a)   Buyer hereby assumes, undertakes, and will pay or otherwise
discharge, and will indemnify and hold Seller harmless against:

            (i)   all claims, losses, liabilities, damages, costs and expenses,
                  including, without limitation, reasonable fees and expenses of

                  defense (at trial and appellate levels and otherwise) of any
                  claim or action brought by or against Seller (hereinafter
                  collectively called 'Losses') arising out of, based upon, or
                  alleging any matter involving an Assumed Obligation or breach
                  of any representation, warranty or covenant by Buyer herein,
                  and

            (ii)  all costs and expenses of Seller (including, without
                  limitation, reasonable fees and expense of attorneys) incurred

                  under the indemnity provided in this Section.

      (b)   Promptly after receipt by Seller of notice of the assertion of any

reimbursement may be sought against

audit), Buyer shall be entitled to participate in and, to the extent Buyer 
elects by written notice to Seller within thirty (30) days after receipt by 
Seller of notice of such Assertion, to assume the defense of such Assertion, 
at its own expense, with counsel chosen by it which shall be reasonably 
satisfactory to Seller.  Notwithstanding that Buyer shall have elected by 
such written notice to assume the defense of any Assertion, Seller shall have 
the right to participate in the investigation and defense thereof, with 
separate counsel chosen by Seller, but in such event the fees and expenses of 
such separate counsel shall be paid by Seller.


      (d)   Notwithstanding anything in this Section to the contrary,

            (i)   Buyer shall have no obligation with respect to an Assertion
                  if, in connection therewith, Seller, without the written
                  consent of Buyer, shall settle or compromise any action or 
                  consent to the entry of any judgment, and

            (ii)  Buyer shall not, without the written consent of Seller, (A) 
                  settle or compromise any action or consent to the entry of any
                  judgment which does not include as an unconditional term
                  thereof the delivery by the claimant or plaintiff to Seller of
                  a duly executed written release of Seller from all liability
                  in respect of such action, which release shall be satisfactory
                  in form and substance to counsel for Seller, or (B) settle or
                  compromise any action in any


                                       28


                  manner that, in the sole judgment of Seller or its counsel,
                  may materially and adversely affect Seller other than as a
                  result of a money damages or other money payments.

8.3   Arbitration

      (a)   Any dispute, controversy or claim asserted by either party against
the other, including any issue as to whether or not a claim is arbitrable,
arising out of or relating to this Agreement or any document or agreement
executed pursuant to this Agreement or the breach thereof, and including without
limitation any claim for indemnification pursuant to Article 8 hereof, shall be
settled by arbitration if so requested by either party pursuant to
Section 8.3(b) below.  The party intending to file a notice of arbitration shall
provide the other party fifteen (15) days prior written notice of its intent to
file for an arbitration.  During such fifteen (15) day period the parties agree
that a senior officer of each party shall meet personally in Chicago, Illinois
to discuss, in good faith efforts, to resolve the dispute(s).  If the party
receiving notice refuses to meet or fails to appear on the agreed upon date of
such meeting, the notifying party may file its notice of arbitration and include
a statement indicating the receiving party's unwillingness to informally meet to
resolve the dispute(s).  The arbitration shall be conducted by one arbitrator,
who shall be appointed pursuant to the Commercial Arbitration Rules of the
American Arbitration Association ('AAA').  The arbitration shall be held in
Chicago, Illinois and shall be conducted in accordance with the Commercial
Arbitration Rules of the AAA, except that the rules set forth in this
Section 8.3 shall govern such arbitration to the extent that they conflict with
the rules of the AAA.


                                       29


      (b)   Upon written notice by a party to the other party of a request for
arbitration hereunder, the parties shall use their best efforts to cause the
arbitration to be conducted in an expeditious manner, the parties using their
best efforts to cause the arbitration to be completed within sixty (60) days
after selection of the arbitrator.  The arbitration shall apply New Jersey law
in accordance with Section 10.13 of this Agreement, except to the extent that
those laws conflict with either the Commercial Arbitration Rules of the AAA or
the provisions of this Section 8.3.  All other procedural matters shall be
within the discretion of the arbitrator.  In the event a party fails to comply
with the procedures in any arbitration in a manner deemed material by the
arbitrator, the arbitrator shall fix a reasonable period of time for compliance
and, if the party does not comply within said period, a remedy deemed just by
the arbitrator, including an award of default, may be imposed.

      (c)   Neither party shall be entitled to seek, nor shall the arbitrator 
be empowered to award, punitive, consequential, exemplary or indirect 
damages.  The determination of the arbitrator shall be final and binding on 
the parties.  Judgment upon the award rendered by the arbitrator may be 
entered in any court having jurisdiction thereof.

      Any announcements or similar publicity with respect to this Agreement or
the transactions contemplated herein shall be approved by both Seller and Buyer

herein may be waived by the party entitled to the benefit thereof only by a
written instrument signed by the party granting such waiver, but such waiver or
failure to insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.  The failure of any party hereto to

construed to be a waiver of any such provision, nor in any way to affect the
validity of this Agreement or any part thereof or the right of any party
thereafter to enforce each and every such provision.  No waiver of any breach of
this Agreement shall be held to be waiver of any other or subsequent breach.
