                                SUPPLY AGREEMENT


     This SUPPLY AGREEMENT (this "Agreement"), is made and entered into this
                                  ---------
16th day of April, 2001, by and between ONDEO NALCO COMPANY, a Delaware
corporation ("Nalco") and GEO SPECIALTY CHEMICALS, INC., an Ohio corporation
              -----
("GEO").
  ---

                            INTRODUCTORY PARAGRAPH

     Nalco and GEO have executed and delivered an Asset Sale and Purchase
Agreement dated April 10, 2001 (the "Purchase Agreement") pursuant to which
                                     ------------------
Nalco is to acquire certain of the assets and assuming certain liabilities of
the Business (as defined in the Purchase Agreement).  Prior to the date hereof,
the Business obtained certain products from GEO plants located in Harrison, New
Jersey and Cedartown, Georgia (the "Facilities").  The Facilities are Excluded
                                    ----------
Assets under the Purchase Agreement.  Nalco desires to continue to obtain such
products from GEO and GEO desires to provide such products on the terms set
forth herein.

                                   AGREEMENTS

     In consideration of the respective representations, warranties, covenants,
agreements and conditions contained herein and in the Purchase Agreement, the
parties hereto agree as follows:

     1.   Definitions.  Capitalized terms used herein without definition have
          -----------
the meanings assigned to them in the Purchase Agreement.

          "Calcium Stearate Products" means those Products designated as such on
           -------------------------
Schedule I Part I attached hereto.
-----------------

          "Other Paper Industry Products" means those Products designated as
           -----------------------------
such on Schedule I Part II attached hereto.
        ------------------

          "Products" means the Calcium Stearate Products and the Other Paper
           --------
Industry Products supplied to the Business by the Facilities prior to the
Closing Date, as set forth on Schedule I attached hereto, as the same may be
                              ----------
modified from time to time in the manner provided herein or therein.

          "Paper Industry" means the market served by the Business prior to the
           --------------
date of this Agreement, including process aids and functional additives
(additives, coating lubricants, defoamers, felt conditioners, cleaners, wet
strength resins and de-inking chemicals) for use in paper coating, pulping,
papermaking and recycling.
<PAGE>

     2.   Supply of Products.
          ------------------

          (a)  During the terms specified in this Agreement, (i) Nalco shall
purchase from GEO, and GEO shall supply to Nalco, the Business' requirements for
Calcium Stearate Products and (ii) Nalco shall purchase from GEO, and GEO shall
supply to Nalco, Nalco's desired quantities of Other Paper Industry Products as
may be designated from time to time pursuant to this Agreement.  Not later than
the first week of each month during the term of this Agreement, Nalco shall
provide to GEO a forecast of its requirements for Calcium Stearate Products and
a forecast of the desired quantities of Other Paper Industry Products for the
balance of the current month and for the two (2) months following.

          (b)  From time to time during the term of this Agreement, Nalco will
issue purchase orders for Products setting forth specific Products and
quantities of each and indicating the shipping designations and desired delivery
dates.  Nalco shall issue orders in advance of desired delivery dates and GEO
shall ship the Products consistent with the past practice of the Business.

          (c)  All Products shall be of the same quality as GEO produces for its
own applications.  GEO shall provide certificates of analysis for all Products
sold to Nalco.

          (d)  The sale of Products to Nalco shall be subject to the general
terms and conditions of sale attached hereto as Schedule II.  In the event that
                                                -----------
there are any inconsistencies between the terms of this Agreement and the terms
on Schedule II, the terms of this Agreement shall govern.
   -----------

          (e)  Products sold to Nalco shall be manufactured and packaged in
accordance with the specifications for Products used by GEO immediately prior to
the Closing Date (as defined in the Purchase Agreement); provided, however, that
                                                         -----------------
from and after the date of this Agreement, Nalco shall have no right to use the
name "GEO" or any variation thereof on such packaging or other materials other
      ---
than as expressly set forth in Section 7.3 of the Purchase Agreement or any
other agreement entered into in connection therewith.

     3.   Increase in Supply.
          ------------------

          (a)  During the first year of this Agreement, GEO shall have no
obligation to sell to Nalco more than One Hundred Ten Percent (110%) of the
annual volume of any class of each Product manufactured in the calendar year
2000.  Thereafter, GEO shall have no obligation to sell to Nalco more than One
Hundred Ten Percent (110%) of the amount of each class of Product that was sold
to Nalco during the previous year provided, however, that GEO shall make a good
                                  --------  -------
faith effort to meet orders for quantities in excess of the One Hundred Ten
Percent (110%) commitment (the "Excess Orders").  If GEO is unable to meet the
                                -------------
Business's Excess Orders for Products, and if such Excess Orders are within the
forecasts provided by Nalco pursuant to Section 2(a), Nalco shall be permitted
to purchase Products from other suppliers in such amounts as may be necessary to
satisfy any volume requirements imposed by such supplier,

                                       2
<PAGE>

notwithstanding Nalco's obligations pursuant to Section 2(a)(i). If GEO is
unable to meet the Excess Orders for Products, and if such Excess Orders are not
within the forecasts provided by Nalco pursuant to Section 2(a), Nalco shall be
permitted to purchase Products from other suppliers but only to the extent of
GEO's failure to meet such Excess Orders

          (b)  For purposes of calculating volumes, to the extent that any
Product is modified slightly to create a new, but closely related product, it
shall be considered to be the Product that was modified.  It shall also be
considered to be the Product that was modified for purposes of pricing unless
GEO can document that the cost of manufacturing the new Product is greater than
the cost of manufacturing the original Product.

     4.   Price for Products.
          ------------------

          (a)  GEO shall sell each Product to Nalco at the price set forth on
Schedule IV, subject to adjustment as provided herein.
-----------

          (b)  The cost to be charged to Nalco for Products may be adjusted
effective as of the first day of each calendar quarter, upon thirty (30) days
prior written notice to Nalco, to the extent of an actual, documented change in
the purchase price of raw materials used to produce the Product, provided, that
                                                                 --------  ----
Nalco shall be given prompt written notice of any proposed changes in the
purchase price of raw materials used to produce the Products and if Nalco is
able to obtain such raw materials at a lower price from another supplier, Nalco
may assign to GEO Nalco's right to purchase from  such other supplier at such
lower price (or the parties may agree that such lower price shall be utilized in
determining the cost to be charged to Nalco for the Products), provided,
                                                               ---------
further, that GEO shall not be obligated to accept such assignment or make such
-------  ----
agreement if to do so would cause GEO to incur additional costs which could not
otherwise be passed on to Nalco pursuant to this Agreement.  The initial raw
material component of the prices for the Products shall be as set forth on
Schedule IV and shall reflect the average of actual raw material prices for the
-----------
first quarter of 2001.  Subsequent changes to raw material prices shall be
calculated by taking the average of the actual prices for the relevant raw
material purchased by GEO in prior quarter.

          (c)  The overhead cost of producing Products shall be adjusted (upward
or downward, as applicable) on the first day of each calendar year based on
either "Method A" or "Method B" (both of which terms are defined below).
        --------      --------

          (d)  Method A shall be the initial method for adjusting the overhead
cost of producing Products.  During the term of this Agreement, Nalco may, not
less than ninety (90) days prior to the end of a calendar year, serve written
notice on GEO of Nalco's election that Method B shall be used to determine the
relevant annual adjustment for the next and each successive year, provided,
                                                                  --------
however, that once such election has been made, it shall continue to apply until
-------
the earlier to occur of (i) this Agreement terminating in accordance with its
terms or (ii) such time as the only material manufacturing activities at either
of the Facilities relate to the manufacture of Products hereunder.  In the event
that the only material manufacturing activities

                                       3
<PAGE>

at either of the Facilities relate to the manufacture of Products hereunder,
Nalco may, upon sixty (60) days prior written notice to GEO (to expire at the
end of a month) elect that, effective as of the end of such sixty (60) day
period, Method A shall, once more, be used to determine the relevant annual
adjustment for the balance of the relevant year, if any, and each successive
year. If such an election is made by Nalco, the applicable price for Products at
the effective time of such election shall be the price that would have been
payable if Nalco had, from the date hereof, continuously used Method A to
calculate the overhead adjustment.

          "Method A" means that the overhead shall be adjusted by ten percent
           --------
(10%) of the annual change in the energy component of the Producer Price Index
for Finished Goods, as reported for the month of October by the Department of
Labor and by ninety percent (90%) of the annual change in the Employment Cost
Index (Total Compensation) as reported for the third quarter by the Department
of Labor.  For example, if the overhead cost for a product is Ten Cents ($.10)
and the energy component of the Producer Price Index for Finished Goods
increases by three percent (3%) as compared to the previous October and the
Employment Cost Index (Total Compensation) increases by four percent (4%) as
compared to the previous third quarter, the increase in the overhead cost will
be calculated as follows: 10% x 3% x $.10 + 90% x 4% x $.10 = $.0003 + $.0036 =
an increase of $.0039.  Therefore, the new overhead cost would be $.1039.  In
any year in which Nalco can show with a reasonable degree of certainty that the
aggregate profit margins for Nalco earned on arms' length and stand alone sales
of Products to customers of the Business (i.e., sales of Products that are not
bundled or tied to the sale of other Nalco products) is less than the aggregate
margin heretofore earned by GEO on such sales (being in the range of twenty
seven percent (27%) to thirty percent (30%) (without deducting the cost of
freight)), and also represents to GEO that market pressures would not permit the
increases in prices resulting from the application of Method A to be passed
through to Nalco's customers, no such adjustment to the price of Products shall
be made in the relevant year.

          "Method B" means that the overhead cost shall be calculated or
           --------
adjusted, as the case may be, effective as of the first day of each calendar
year based upon the actual cost to GEO of manufacturing the Products for Nalco,
the calculation and allocation of such costs to Nalco being consistent with
those used to prepare the income statement for the Business for the calendar
year 2000, as set forth in Schedule 3.4 of the Purchase Agreement.  GEO's
                           ------------
computation of such actual costs and its supporting documentation may be
reviewed by Nalco for consistency and on an annual basis during normal business
hours at Nalco's cost by an independent certified public accounting firm
selected by Nalco and reasonably acceptable to GEO; provided, that:  (i) any
                                                    --------  ----
party reviewing such books and records shall, if requested, enter into a
confidentiality agreement with GEO, and (ii) GEO's data shall be presumed
correct once a review has been performed and such data is unchallenged or
confirmed as correct in such review, or, if unreviewed, after two (2) years from
the date of entry on GEO's books. Any dispute between the parties concerning
this Method B will be conclusively determined in the manner contemplated by
Section 2.4.2 of the Purchase Agreement.  Prior to the first annual computation
of costs by GEO, Nalco shall continue to pay amounts due hereunder in accordance
with Method A, with a payment to be made by GEO or Nalco to the other (as
applicable) once the actual costs payable under this Method B have been agreed
or otherwise determined.

                                       4
<PAGE>

          (d)  All invoices shall be directed to Nalco.  Payment for Product
shall be made within thirty (30) days of the date of shipment.

     5.   Assignment.
          ----------

          This Agreement may not be assigned by either party without the prior
written consent of the other party; provided, however, that no prior consent
                                    --------  -------
shall be needed for either party to assign this Agreement to an Affiliate or to
a purchaser of substantially all of the assets of the Business or the
Facilities.

     6.   Intellectual Property.
          ---------------------

          Except as provided in the Purchase Agreement, nothing contained herein
shall grant, or be construed to grant, to Nalco any rights or licenses in the
technology or patents relating to Products supplied hereunder or in the
trademarks under which such Products are supplied.

     7.   Title.
          -----

          Title to all Products shall pass from GEO to Nalco upon delivery by
GEO to the carrier in accordance with the instructions of Nalco.

     8.   Term; Termination; Default.
          --------------------------

          (a)  GEO shall supply the Calcium Stearate Products for an initial
period of five (5) years from the date hereof (the "Calcium Stearate Period").
                                                    -----------------------
Thereafter, this Agreement shall be renewed automatically with respect to the
Calcium Stearate Products for successive one year periods unless either party
provides the other party with written notice of its intent to cease purchasing
or supplying (as applicable) Calcium Stearate Products hereunder no less than
six (6) months prior to the end of the Calcium Stearate Period or any renewal
period.

          (b)  GEO shall supply the Other Paper Industry Products for a period
of one (1) year from the date hereof (the "Other Paper Products Period").
                                           ---------------------------
Thereafter, this Agreement shall be renewed automatically with respect to the
Other Paper Industry Products for successive one year periods unless either
party shall give the other party written notice of its intent to cease
purchasing or supplying (as applicable) Other Paper Products hereunder no less
than six (6) months prior to the end of the Other Paper Products Period or any
renewal period.

          (c)  This Agreement, and any rights granted hereunder, may be
terminated (i) in whole or in part by the mutual written consent of the parties
hereto, or (ii) with respect to either the Calcium Stearate Products or the
Other Paper Industry Products, by either party by written notice to the other
party upon any material breach or default of any provision or

                                       5
<PAGE>

obligation of this Agreement relating to such Products and failure to cure such
breach or default within sixty (60) days after written notice thereof.

          (d)   Any termination of this Agreement pursuant to the preceding
paragraph shall be without prejudice to any other remedies which either party
may have against the other arising out of any breach or default and shall not
affect any rights or obligations of either party arising under this Agreement
prior to such termination.  In the event of termination by Nalco, Nalco shall
pay GEO for all Products ordered, processed, packaged and available for shipment
prior to the effective date of termination and shall reimburse GEO for all
unused raw materials for Products not usable by GEO.  All such Products and
unused raw materials shall be shipped to the Nalco customer or to such other
location designated by Nalco.   Upon termination of the obligations of the
parties to purchase or supply (as applicable) any category of Products under
this Agreement, GEO agrees to provide Nalco with access to the technology and
know-how in its possession so as to permit Nalco's manufacture (by itself or by
a contract supplier) of the Products so terminated.  No such access shall be
provided to any technology or know-how for Products the supply of which has not
been properly terminated in accordance with the terms of this Agreement.  Nalco
agrees to hold such technology and know-how in strict confidence and it will
limit its use of such technology and know-how to the manufacture of products for
use in the Business.  Nalco's rights under this Section 8(d) shall not permit it
to receive any intellectual property constituting an Excluded Asset under the
Purchase Agreement.

     9.   Limitation of Warranties.
          ------------------------

          EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, GEO MAKES NO
WARRANTY, EXPRESS OR IMPLIED, OF ANY KIND, INCLUDING, BUT NOT LIMITED TO, ANY
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE WITH RESPECT TO
ANY OF THE SERVICES PROVIDED HEREUNDER, IF ANY, OR ANY OF THE PRODUCT PRODUCED
AND DELIVERED HEREUNDER.  THIS PROVISION WILL SURVIVE THE EXPIRATION OR
TERMINATION OF THIS AGREEMENT.  IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR
PUNITIVE, CONSEQUENTIAL, SPECIAL, INCIDENTAL OR SIMILAR DAMAGES UNDER OR IN
CONNECTION WITH THIS AGREEMENT.

     10.  Confidentiality and Verification.  The parties shall use reasonable
          --------------------------------
efforts to maintain the confidentiality of any proprietary or confidential
information provided by either party in connection with this Agreement.  Each
party hereto shall provide the other party with reasonable access to its books
and records to permit verification of each party's compliance with the terms of
this Agreement.

     11.  GEO Sales to Third Parties.  No provision of this Agreement or the
          --------------------------
Purchase Agreement shall prevent GEO from supplying or tolling products similar
to the Products to any third party not engaged in the Paper Industry.

                                       6
<PAGE>

     12.  Nalco Sales to Third Parties.  Nalco hereby covenants that it shall
          ----------------------------
not, directly or indirectly, during the term of this Agreement, sell Products
supplied by GEO to (i) any third party not engaged in the Paper Industry or (ii)
any third party engaged in the Paper Industry which Nalco knows (or ought
reasonably to know) intends to use such Product other than in the Paper
Industry.

     13.  Miscellaneous.  This Agreement and the Purchase Agreement are a
          -------------
complete and exclusive statement of the terms of the agreement between the
parties with respect to the subject matter hereof and may not be changed,
terminated, modified or waived except by an instrument in writing executed by
both parties hereto.  This Agreement may be executed in counterparts, each of
which shall be considered an original, but all of which together shall
constitute the same instrument.  No waiver by Nalco or GEO of any breach of or
default under this Agreement shall constitute a wavier of any subsequent breach
or default.  The parties hereby acknowledge that GEO is acting solely in the
capacity as an independent contractor and nothing in this Agreement shall be
construed to constitute GEO as an agent of Nalco.  This Agreement shall be
binding and inure to the benefit of the parties hereto and their respective
successors and assigns.

          -------
Agreement shall be in writing and shall be (a) delivered personally; (b) sent by
