        pursuant to paragraphs (d) or (e) hereof (the "Interim
        Period"), in compliance with applicable law and in
        accordance with the following principles:  each Selling
        Company that has retained a Retained Business may retain
        title to the Retained Business or may transfer the Retained
        Business to a newly formed Subsidiary that is wholly owned
        directly or indirectly by Grace at Grace's sole cost and
        expense.  To the maximum extent permissible by applicable
        law, Buyer shall operate the business thereof and make
        decisions in connection therewith.  In all other respects,
        Grace shall cause each Selling Company that has a Retained
        Business (or each Subsidiary to which such Retained
        Business has been transferred) to continue to operate such
        Retained Business in the geographic areas in which it was
        operated prior to the Closing in the ordinary course of
        business, consistent with past practice.  Such Selling
        Company or Grace Subsidiary, as applicable, shall be deemed
        to have been granted licenses by the Buyer Group to use all
        Intellectual Property Rights previously used by such
        Selling Company in connection with the Retained Business
        and shall pay royalties to Buyer (or a designated member of
        the Buyer Group) in exchange for such licenses in the
        amount, if any, provided for in the agreements between such
        Selling Company or Grace Subsidiary, as applicable, and
        other members of the Grace Group in effect prior to the
        Closing.  If such Suspended Conveyance involves the
        retention by such Selling Company of the capital stock of a
        Transferred Company or Transferred Joint Venture, such
        Transferred Company or Transferred Joint Venture shall
        continue operating the Retained Business and shall be
        granted such licenses and pay such royalties.  If no
        agreement previously existed between the Selling Company or
        Grace Subsidiary and other members of the Grace Group
        providing for royalties, the license to continue operating
        the Retained Business provided for herein shall be on a
        royalty free, paid-up basis. 
         
                       (ii) If Grace gives Buyer notice of its
        election pursuant to this Section 2.5, at the Closing and
        at all times thereafter, Buyer shall have the option in its
        sole discretion upon three days written notice to Grace of
        having the Retained Business conveyed to it without regard
        to whether or not the consent or approval of the relevant
        Governmental Authority with respect to the Suspended
        Conveyance has been obtained.  If Buyer decides to exercise
        the option pursuant to this subsection (ii) such that the
        business otherwise subject to the Suspended Conveyance
        shall be conveyed to Buyer at the Closing, then the payment
        of the Local Purchase Price relating to such business will
        be made as otherwise set forth in this Agreement and not as
        contemplated by Section 2.5(b)(ii).

                  (d)  Subject to Section 2.5(e), each Selling
        Company or Grace Subsidiary, as applicable, that is
        operating a Retained Business shall proceed as
        expeditiously as possible and use reasonable efforts to
        sell such Retained Business to a purchaser that is not an
        affiliate of the Buyer Group or the Grace Group (an
        "Independent Purchaser"); the manner of such sale (which
        may be by way of "auction" or other competitive bidding
        process, negotiated sale or other manner deemed
        appropriate) and the terms of any such sale shall be
        subject to the approval of Buyer, to the extent permitted
        by applicable law, which approval shall not be unreasonably
        withheld or delayed.  Upon the closing of any such sale,
        Grace shall pay to Buyer, as an adjustment of the Total
        Purchase Price, the proceeds of such sale, which amount
        shall be net of expenses directly related to such sale (but
        shall not be reduced by any Taxes incurred in connection
        with such sale, but the liability for transfer taxes shall
        be allocated in accordance with Section 6(b) of the Tax
        Procedures Agreement) which amount shall be adjusted to
        reflect Buyer's entitlement (on an economic basis) to the
        earnings of the Retained Business during the Interim Period
        and Grace's entitlement to reimbursement for the costs
        relating to capital expenditures incurred with Buyer's
        consent, with interest on such net amount.

                  (e)  At Buyer s request, any Selling Company or
        Grace Subsidiary, as applicable, operating a Retained
        Business shall delay all efforts to achieve a sale to an
        Independent Purchaser for a period ending no later than 15
        months after the Closing Date to permit the Buyer Group to
        obtain all consents and approvals of Governmental
        Authorities required for the purchase by the Buyer Group of
        the Retained Business.  If the Buyer Group obtains all such
        consents and approvals, such Selling Company or Grace
        Subsidiary, as applicable, shall convey the Retained
        Business to a member of the Buyer Group designated by
        Buyer.  The purchase price for the assets and business so
        conveyed shall be adjusted to reflect Buyer's and Grace's
        respective entitlement in accordance with the provisions of
        the last sentence of Section 2.5(d).

                  (f)  Buyer agrees to reimburse Grace for
        reasonable out-of-pocket expenses related to the sale or
        attempted sale of a Retained Business pursuant to Section
        2.5(e) (other than Taxes incurred in connection with such
        sale, but the liability for transfer taxes shall be
        allocated in accordance with Section 6(b) of the Tax
        Procedures Agreement) to the extent not deducted from the
        proceeds thereof in accordance with the terms of Section
        2.5(d).  No overhead or administrative cost charged by WRG,
        Grace or any member of the Selling Group to a Retained
        Business will be reimbursed unless its incurrence was
        approved in advance by Buyer.

        the expense thereof borne in accordance with Article 17,
        the Selling Companies shall, and shall cause the other
        members of the Grace Group to, execute and deliver, or
        cause to be executed and delivered, all such deeds,
        assignments, and other documents, and take or cause to be
        taken all such other actions, as Buyer or any of the other
        Buying Companies reasonably deems necessary or desirable to
        put the Buying Companies in actual possession or operating
        control of the Total Dearborn Assets and the Transferred
        Companies, and of Grace's rights with respect to the
        Transferred Investment, or to more fully and effectively
        vest in the Buying Companies, or to confirm their title to
        and possession of, the Total Dearborn Assets, the
        Transferred Shares, the Transferred Interests and the
        Transferred Investment, including, without limitation, all
        reasonable actions necessary to effectively transfer all of
        the Selling Companies' interests in any of such assets as
        to which the consent of any third party to the transfer
        thereof shall not have been obtained prior to Closing.

             3.8  Further Assurances of the Buying Companies.  At
        any time and from time to time after the Closing, at the
        request of Grace or any of the other Selling Companies,
        with the expense thereof borne in accordance with Article
        17, the Buying Companies shall, and shall cause the other
        members of the Buyer Group to, execute and deliver, or
        cause to be executed and delivered, all such documents, and
        take or cause to be taken all such other actions, as Grace
        or any of the other Selling Companies reasonably deems
        necessary or desirable to more fully and effectively divest
        Grace and the other Selling Companies of responsibility for
        the Total Dearborn Liabilities and incidents of ownership
        of the Total Dearborn Assets, the Transferred Shares, the
        Transferred Interests and the Transferred Investment,
        including, without limitation, all reasonable actions
        necessary to effectively transfer all of the Selling
        Companies' obligations with respect to any of such assets
        as to which the consent of any third party to the transfer
        thereof shall not have been obtained prior to Closing.

             3.8A Total Excluded Assets and Total Excluded
        Liabilities.  On or prior to the Closing Date, Grace shall
        (a) cause all rights, properties and other assets of the
        Transferred Companies that are Total Excluded Assets to be
        sold, assigned or otherwise conveyed by the Transferred
        Companies to Grace or Grace's designees (which designees
        shall in no event include any of the Transferred
        Companies), and Grace or such transferee shall assume all
        liabilities (absolute, accrued, contingent or otherwise,
        known or unknown) and obligations related to such Total
        Excluded Assets, and (b) assume or cause one of its
        designees (which designees shall in no event include any of
        the Transferred Companies) to assume all liabilities and
        obligations of the Transferred Companies that are Total
        Excluded Liabilities.  The sale, assignment or conveyance
        of such Total Excluded Assets and the assumption of such
        Total Excluded Liabilities shall not create any liabilities
        (absolute, accrued, contingent or otherwise, known or
        unknown) or obligations of the Transferred Companies that
        shall survive the Closing; provided, however, that to the
        extent Grace does not sell, assign, or convey the Total
        Excluded Assets pursuant to clause (a) or assume the Total
        Excluded Liabilities pursuant to clause (b) prior to the
        Closing Date, Grace shall continue to sell, assign, convey
        or assume (or cause to be sold, assigned, conveyed or
        assumed) the Total Excluded Assets or Total Excluded
        Liabilities after the Closing Date and shall remain liable
        for such Total Excluded Liabilities.  Grace shall be solely
        responsible for the costs and expenses associated with the
        transfer of such Total Excluded Assets and the assumption
        of related liabilities and obligations.  The costs and
        expenses relating to the assumption of such Total Excluded
        Liabilities shall be paid in accordance with Article 17.

        which basis of presentation will be described in Note 1
        thereto, and in conformity with U.S. GAAP, and accompanied
        by a report of Price Waterhouse, which will include a

        same account classifications, closing procedures and levels
        of materiality as those used in the preparation of the 1995
        Dearborn Statement of Net Assets.  If Buyer is able to
        establish that the representation in Section 5.6 with
        respect to the 1995 Dearborn Statement of Net Assets was
        inaccurate, then both the 1995 Dearborn Statement of Net
        Assets and the Closing Net Amount shall be restated using
        the corrected accounting principles and levels of
        materiality that would cause such representation to be
        accurate, and the Total Purchase Price shall be adjusted
        accordingly.  All amounts deemed paid and discharged
        pursuant to Section 16.3 or retained or assumed by any
        member of the Grace Group (or for which Grace has agreed to
        indemnify the Buyer Group) as of the Closing Date in
        accordance with any of the Ancillary Agreements, shall be
        excluded from the assets and liabilities to be considered
        in the calculation of the Closing Net Amount.

             4.4  Closing Statement.  As soon as practicable after
        the Closing, but in no event later than 120 calendar days
        after the Closing, Grace shall deliver to Buyer a statement
        setting forth Grace's determination of the Closing Net
        Amount (the "Closing Statement"), together with a report of
        Price Waterhouse stating whether the Closing Net Amount
        shown on the Closing Statement has been determined, in all
        material respects, in accordance with the terms of this
        Agreement.  Upon and after delivery to Buyer of the Closing
        Statement, Buyer's independent accountants accompanied by
        Buyer shall, upon request, be given access to Price
        Waterhouse's working papers to facilitate Buyer's review of
        the Closing Statement.

             4.A  Pre-Closing Financial Statements Price
        Adjustments.

                  (a)  1995 audited statements.  As promptly as
        practicable after the date of this Agreement, but in no
        event later than April 10, 1996, Grace shall deliver to
        Buyer the audited 1995 Dearborn Statement of Net Assets and
        1995 Dearborn Statement of Pretax Income. 

                  (b)  Working capital adjustment.  The Total
        Purchase Price shall be increased by the amount, if any, by
        which the 1995 Net Amount exceeds US $71.9 million or
        decreased by the amount, if any, by which the 1995 Net
        Amount is less than US $71.9 million. 

                  (c)  Contribution Margin adjustment.

                       (i)  Not later than 15 calendar days after
        delivery of the 1995 Dearborn Statement of Pretax Income,
        Grace shall deliver a statement to Buyer as to the amount,
        if any, of the price adjustment under this subsection as
        computed by Grace, together with a schedule of all audit
        adjustments made in the preparation of the 1995 Dearborn
        Statement of Pretax Income, indicating which are due to
        Non-Recurring Events.  Buyer and Grace agree that the audit
        adjustments set forth on such schedule will be the only
        items which the parties may dispute in connection with the
        calculation of the Contribution Margin adjustment.

                       (ii) If the 1995 Contribution Margin Amount
        exceeds US $70.5 million, there shall be no resulting price
        adjustment.

                       (iii) If the 1995 Contribution Margin Amount
        is less than US $70.5 million, the following shall apply:

                            (A)  There shall be no resulting price
        adjustment with respect to that portion of the shortfall in
        the 1995 Contribution Margin Amount which is attributable
        to Non-Recurring Events. 

                            (B)  That portion of the shortfall in
        the 1995 Contribution Margin Amount which is attributable
        to Non-Recurring Events shall be subtracted from the total
        shortfall, and US $625,000 shall be deducted from the
        resulting amount.

                            (C)  If the amount computed pursuant to
        subsection (c)(iii)(B) of this Section is greater than
        zero, then such amount as so computed shall be multiplied
        by the Earnings Multiple and the Total Purchase Price shall
        be decreased by the resulting amount.  Such resulting
        amount is the "Contribution Margin Adjustment."

             4.AA Post-Closing Financial Statement Price
        Adjustment.  The Total Purchase Price shall be increased by
        the amount of any increase, or decreased by the amount of
        any decrease, in the amount of the Closing Net Amount from
        the 1995 Net Amount.

             4.5  Acceptance.  If Buyer does not object to the
        Closing Net Amount shown on the Closing Statement delivered
        by Grace, by written notice of objection delivered to Grace
        within 60 calendar days after Buyer's receipt of such
        statement, describing in reasonable detail each of its
        proposed adjustments to Grace's determination thereof, then
        the Closing Net Amount shown on the Closing Statement shall
        be final and binding on all parties to this Agreement.  If
        Buyer does not object to the amount of the Contribution
        Margin Adjustment shown on the statement delivered by Grace
        under Section 4.A(c)(i), by written notice of objection
        delivered to Grace within 60 calendar days after Buyer's
        receipt of such statement, describing in reasonable detail
        each of Buyer's proposed adjustments to the price reduction
        as computed by Grace, then the Contribution Margin
        Adjustment as proposed by Grace shall be final and binding
        on all parties to this Agreement.

             4.6  Non-Acceptance, Resolution of Disputes.

                  (a)  If Buyer objects to the Closing Net Amount
        shown on the Closing Statement or the Contribution Margin
        Adjustment as shown on Grace's statement under Section
        4.A(c)(i) within the time period specified in Section 4.5,
        then Buyer and Grace shall promptly endeavor to agree upon
        the proper amount of all items in dispute.  If a written
        agreement resolving any disputed item has not been reached
        within 45 calendar days after the date of receipt by Grace
        of Buyer's notice of objection to the Closing Net Amount or
        the Contribution Margin Adjustment, then either Grace or
        Buyer may, by notice to the other refer their differences
        to a "Big Six" accounting firm to be agreed upon, other
        than Price Waterhouse or Buyer's independent accountants
        (the "CPA Firm").  The CPA Firm, acting as experts and not
        as arbitrators, shall determine in accordance with the
        terms of this Article the differences so submitted,
        including the determination of what adjustments, if any,
        must be made in one or more of the items reflected in the
        Closing Statement delivered by Grace pursuant to Section
        4.4 in order for the Closing Net Amount to be determined in
        accordance with the provisions of this Agreement or in one
        or more components of the Contribution Margin Adjustment as
        shown on the statement delivered by Grace under Section
        4.A(c)(i) in order for the Contribution Margin Adjustment
        to be determined in accordance with the provisions of this
        Agreement.  In any determination by the CPA Firm of an
        adjustment to the Contribution Margin Adjustment, Grace
        shall have the burden of proving the extent to which any
        shortfall was caused by a Non-Recurring Event.  The
        determination of the CPA Firm shall be determined in
        accordance with the provisions of this Agreement and shall
        be final and binding on all parties to this Agreement.

                  (b)  The fees and expenses of the CPA Firm for
        any determination under this Article shall be shared as
        follows:  if the dispute involves the Closing Net Amount,
        Grace shall bear a portion of such fees and expenses equal
        to the total amount of such fees and expenses multiplied by
        a fraction, the numerator of which shall be the difference
        between the Closing Net Amount as determined by the CPA
        Firm and the Closing Net Amount as finally proposed by
        Grace, and the denominator of which shall be the difference
        between the Closing Net Amount as finally proposed by Buyer
        and the Closing Net Amount as finally proposed by Grace;
        or, if the dispute involves the Contribution Margin
        Adjustment, Grace shall bear a portion of such fees and
        expenses equal to the total amount of such fees and
        expenses multiplied by a fraction, the numerator of which
        shall be the difference between the Contribution Margin
        Adjustment as determined by the CPA Firm and the
        Contribution Margin Adjustment as finally proposed by
        Grace, and the denominator of which shall be the difference
        between the Contribution Margin Adjustment as finally
        proposed by Buyer and the Contribution Margin Adjustment as
        finally proposed by Grace.  Buyer shall bear the remainder
        of such fees and expenses.

                  (c)  Nothing herein shall be construed to
        authorize or permit the CPA Firm to (i) determine any
        question or matter whatsoever under or in connection with
        this Agreement or any other Transaction Document except the
        determination of what adjustments, if any, must be made in
        one or more of the items reflected in the Closing Net
        Amount as shown on the Closing Statement delivered by Grace
        in order for the Closing Net Amount to be determined in
        accordance with the provisions of this Agreement, or in one
        or more components of the Contribution Margin Adjustment as
        shown on the statement delivered by Grace under Section
        4.A(c)(i) in order for the Contribution Margin Amount to be
        determined in accordance with the provisions of this
        Agreement, (ii) determine a Closing Net Amount that is
        outside of the range between the Closing Net Amounts as
        finally proposed by Grace and Buyer, respectively, or a
        Contribution Margin Adjustment that is outside of the range
        between the Contribution Margin Adjustments as finally
        proposed by Grace and Buyer, respectively, or (iii) to make
        any change to the dollar amounts specified in Section 4.A,
        which amounts have been established by agreement of the
        parties and may not be changed except in accordance with
        Section 19.6.  Nothing herein shall be construed to require
        the CPA Firm to follow any rules or procedures of any
        arbitration association.  Grace and Buyer each shall
        provide each other and the CPA Firm full access to the
        books and records, any other information, including work
        papers of its accountants, and to any of its employees to
        the extent necessary for any determination under this
        Article.

             4.B  Pre-Closing Adjustment for Certain Additional
        Liabilities.

                  (a)  In the event of a Major Undisclosed
        Liability, as to which Buyer notifies Grace prior to
        Closing, the Total Purchase Price shall be reduced as
        provided in this Section.

                  (b)  For purposes of this Section,

                       (i)  An Undisclosed Liability means any
        liability, determinable or contingent (other than a current
        liability), that was not (1) reflected in the 1995 Dearborn
        Statement of Net Assets or (2) disclosed as of the date
        hereof on any schedule to Articles 5 or 12 of this
        Agreement or the Data Room Schedule as of the date hereof. 
        Liabilities for pensions in Germany or the Netherlands, or
        for employee severance indemnity or premium payments in
        Brazil, Colombia, Venezuela, Italy or France, shall not in
        any event be Undisclosed Liabilities, whether or not they
        are reflected in the 1995 Dearborn Statement of Net Assets
        or described in any schedule to this Agreement.

                       (ii) A Major Undisclosed Liability means an
        Undisclosed Liability that either (a) should be reflected,
        as of the Closing, on a balance sheet prepared in
        accordance with U.S. GAAP, or (b) is such that the
        reasonable estimate, as of the Closing, of the actual
        amount of loss or payment that will directly result from
        the Undisclosed Liability, is US $500,000 or more,
        determined separately for each Undisclosed Liability. 

                  (c)  Except as provided in subsection (d) of this
        Section, the amount of the price reduction for a Major
        Undisclosed Liability shall be, (1) if the Major
        Undisclosed Liability should be reflected, as of the
        Closing, on a balance sheet prepared in accordance with
        U.S. GAAP, the amount that should be so reflected, and (2)
        in all other cases, an amount equal to the reasonable
        estimate, as of the Closing, of the actual amount of loss
        or payment that will directly result from the Major
        Undisclosed Liability. 

                  (d)  This Section shall not entitle the Buying
        Companies to any price adjustment with respect to matters
        as to which the Buying Companies otherwise are entitled to
        be indemnified by the Selling Companies under this
        Agreement or any of the Ancillary Agreements. 

             4.C  Adjustment for Certain Conveyancing Problems.  In
        the event that any asset, property or right transferred or
        to be transferred to the Buying Companies under this
        Agreement, other than (i) items that would be reflected on
        a balance sheet as current assets and (ii) rights under
        contracts or arrangements for the sale of Dearborn products
        to third parties, requires the consent of a third party for
        an effective transfer to the Buying Companies, such consent
        is not obtained, and as a direct result thereof, the Buying
        Companies are unable to use such asset, property or right
        in the Dearborn Business substantially as used by the Grace
        Group prior to the Closing, then the Total Purchase Price
        shall be decreased by an amount equal to the present value
        (using a discount rate of 10%) of the reasonable
        incremental cost to the Buying Companies (net of any
        reduction in costs, such as rent expense, resulting from
        the non-transfer of the asset) of obtaining a substantially
        similar replacement.  If such cost is to be incurred in a
        currency other than U.S. dollars, the amount of the price
        reduction shall be computed in U.S. dollars using the
        applicable exchange rate, as of the Valuation Date,
        referred to in Section 2.4(a).  If the asset is the Grace
        Group's ownership interest in the Dearborn India JV or the
        Dearborn Japan JV, the parties stipulate that the
        applicable price adjustments under this Section will be US
        $100,000 and US $300,000 respectively.

             4.D  Termination Option.  In the event that, in
        Grace's reasonable good faith judgment, the aggregate
        effect of the provisions of Sections 4.A(c), 4.B and 4.C
        will result in a reduction of the Total Purchase Price of
        US $60 million or more, Grace will have the option in its
        sole discretion to terminate this Agreement, unless Buyer
        shall stipulate that the total of such price reductions
        shall in any event be less than US $60 million.  If such
        option is not exercised, nothing set forth herein shall
        limit or otherwise affect the amounts due pursuant to
        Sections 4.A(c), 4.B and 4.C whether such adjustments are
        paid at Closing or otherwise.  Grace's delivery of any
        statement indicating the amount of one or more price
        reductions, even if in excess of the amount specified in
        the prior sentence, shall not be deemed to be a waiver of
        Grace's option to terminate this Agreement pursuant to this
        Section. 

             4.7  Payment of Adjustments.

                  (a)  (i)  Promptly after the Closing Net Amount
        has been finally determined, Grace shall deliver to Buyer a
        statement of the Total Purchase Price reflecting the final
        Closing Net Amount.  After receipt of such statement, the
        Allocation and the Specific Allocation shall be amended to
        reflect the Total Purchase Price as so adjusted, as Grace
        and Buyer shall mutually agree, giving effect to the
        country or countries which account for any such adjustment.

                       (ii) No later than 15 calendar days after
        delivery by Grace of the statement of the Total Purchase
        Price as adjusted for the final Closing Net Amount, all
        resulting Local Purchase Price adjustments shall be settled
        simultaneously based on such statement.  If any such
        resulting Local Purchase Price exceeds the amount
        previously paid with respect thereto, the appropriate
        Buying Company shall pay the amount due to the appropriate
        Selling Company in the manner provided in Section 4.7(c);
        if any such resulting Local Purchase Price is less than the
        amount previously paid with respect thereto, the
        appropriate Selling Company shall refund the amount of the
        overpayment to the appropriate Buying Company in the manner
        provided in Section 4.7(c).  If at the time of settlement
        Grace and Buyer have not agreed on the amended Allocation
        and Specific Allocation, Grace on behalf of the Selling
        Companies shall pay to Buyer on behalf of the Buying
        Companies the aggregate amount of any net overpayment, or
        Buyer on behalf of the Buying Companies shall pay to Grace
        on behalf of the Selling Companies the aggregate amount of
        the net payment due.

                  (b)  (i)  Promptly after the Contribution Margin
        Adjustment has been finally determined, Grace shall deliver
        to Buyer a statement of the Total Purchase Price reflecting
        the final Contribution Margin Adjustment.  After receipt of
        such statement, the Allocation and the Specific Allocation
        shall be amended to reflect the Total Purchase Price as so
        adjusted, as Grace and Buyer shall mutually agree, giving
        effect to the country or countries which account for any
        such adjustment.

                       (ii) If Grace delivers the statement of the
        Total Purchase Price as adjusted for the final Contribution
        Margin Adjustment after the Closing, then not later than 15
        calendar days thereafter, all resulting Local Purchase
        Price adjustments shall be settled simultaneously based on
        such statement.  If any such resulting Local Purchase Price
        exceeds the amount previously paid with respect thereto,
        the appropriate Buying Company shall pay the amount due to
        the appropriate Selling Company in the manner provided in
        Section 4.7(c); if any such resulting Local Purchase Price
        is less than the amount previously paid with respect
        thereto, the appropriate Selling Company shall refund the
        amount of the overpayment to the appropriate Buying Company
        in the manner provided in Section 4.7(c).  If at the time
        of settlement Grace and Buyer have not agreed on the
        amended Allocation and Specific Allocation, Grace on behalf
        of the Selling Companies shall pay to Buyer on behalf of
        the Buying Companies the aggregate amount of any net
        overpayment, or Buyer on behalf of the Buying Companies
        shall pay to Grace on behalf of the Selling Companies the
        aggregate amount of the net payment due.

                  (c)  All adjusting payments with respect to the
        Local Purchase Prices shall be settled by payments in the
        United States in U.S. dollars between Grace, as agent for
        the Grace Group, and Buyer, as agent for the Buyer Group,
        and any amounts due from the Grace Group shall be set off
        against any amounts due from the Buyer Group to the extent
        practicable.  However, any adjustment to a Local Purchase
        Price with respect to which payment was made at the Closing
        in any currency other than U.S. dollars pursuant to Section
        3.6, shall be first determined in U.S. dollars and then
        paid in an amount of local currency equal to the dollar
        value so determined (based on the Payment Exchange Rate on
        the Business Day prior to the date payment is made). 
        Payment shall be made at the local office of the recipient
        within the applicable country or at such other place within
        such country as the recipient shall request.

                  (d)  If the net amount of all adjusting payments
        under subsection (a), or under subsection (b) if paid after
        the Closing, (regardless of where payment is made) is in
        excess of US $100,000, Buyer or Grace shall pay interest to
        the other on the entire amount of the net adjusting payment
        under such subsection owed for the period from the Closing
        Date to the date of payment, at the LIBOR Rate plus three
        percentage points.

                                 ARTICLE 5
                         REPRESENTATIONS BY GRACE

             Grace represents and warrants to Buyer and the other
        Buying Companies as follows:

             5.1  Grace Corporate Status and Authority.  Grace is a
        corporation duly organized, validly existing and in good
        standing under the laws of its jurisdiction of
        organization.  Dearborn U.S. is a limited partnership duly
        formed, validly existing and in good standing under the
        laws of Delaware.  Each Selling Company (other than Grace)
        is a direct or indirect Subsidiary of Grace.  Each member
        of the Grace Group that is a party to this Agreement or one
        of the other Transaction Documents has all requisite power
        and authority to own, lease and operate its properties and
        to carry on the Dearborn Business as now being conducted,
        except as set forth on the Schedule to this Section or
        where the failure to have such power and authority would
        not, individually or in the aggregate, have a Material
        Adverse Effect.  Each member of the Grace Group has full
        legal power to execute and deliver each Transaction
        Document to which it is or will be a party, and will, prior
        to the Closing, have full legal power to perform its
        obligations under such Transaction Document and to
        consummate the transactions contemplated thereby.  The
        execution and delivery by each member of the Grace Group of
        each Transaction Document to which it is or will be a
        party, its performance of its obligations under such
        Transaction Document and the consummation of the
        transactions contemplated thereby will, prior to the
        Closing, have been duly authorized by all required
        corporate action of such member, or by partnership action
        in the case of Dearborn U.S.  Each such member of the Grace
        Group has duly and validly executed and delivered each
        Transaction Document to which it is a party that is being
        executed and delivered simultaneously with this Agreement,
        and each such Transaction Document constitutes a legal,
        valid and binding obligation of such member, enforceable
        against such member in accordance with its terms.  Each
        Transaction Document to be executed by any member of the
        Grace Group at the Closing, when executed and delivered,
        will be duly and validly executed and delivered by, and
        will constitute a legal, valid and binding obligation of
        such member and be enforceable against such member in
        accordance with its terms.  Prior to the Closing, Grace
        will have furnished or made available to Buyer complete and
        correct copies of the Certificate of Incorporation and By-
        Laws (or equivalent organizational documents), as in effect
        at the Closing, of each of the Selling Companies.

             5.2  Transferred Companies' Organizational Status and
        Capitalization.

                  (a)  Each of the Transferred Companies (other
        than Dearborn U.S.) is a corporation duly organized,
        validly existing and in good standing (or the equivalent
        thereof) under the laws of its jurisdiction of organization
        set forth in the Schedule to this Section and each of the
        Transferred Companies has all requisite power and authority
        to own, lease and operate its properties and to carry on
        its business as now being conducted, except as set forth on
        the Schedule to this Section or where the failure to have
        such power and authority would not, individually or in the
        aggregate, have a Material Adverse Effect.  Each of the
        Transferred Companies is duly qualified or licensed to do
        business as a foreign corporation and is in good standing
        in each jurisdiction in which property is owned or leased
        by the Transferred Company or the conduct of the
        Transferred Company's business makes such qualification or
        license necessary, except as set forth on the Schedule to
        this Section or where the failure to be so qualified or
        licensed would not have a Material Adverse Effect.  Grace
        has heretofore furnished or made available to Buyer
        complete and correct copies of the Certificate of
        Incorporation and By-Laws (or equivalent organizational
        documents), as in effect at the Closing, of each of the
        Transferred Companies.

                  (b)  The Schedule to this Section also sets forth
        a true and complete listing of the authorized, issued and
        outstanding capital stock of each Transferred Company
        (other than Dearborn U.S.) and the ownership of such
        capital stock.  Each Selling Company that owns such capital
        stock has good and valid title to the capital stock owned
        by it, in each case free and clear of all Liens.  Except as
        set forth on the Schedule to this Section, there are no
        outstanding shares of capital stock or other voting
        securities of any Transferred Company.  There are (i) no
        outstanding subscriptions, warrants, options, convertible
        securities or other rights to purchase or otherwise acquire
        any capital stock of any such Transferred Company, except
        repurchase rights of the Grace Group with respect to
        capital stock held by certain individuals; (ii) no
        securities of any of the Selling Companies or any of their
        affiliates (including, without limitation, the Transferred
        Companies) convertible into or exchangeable for shares of
        capital stock or voting securities of any Transferred
        Company; (iii) no obligations of the Selling Companies or
        any of their affiliates (including, without limitation, the
        Transferred Companies) to issue, deliver or sell any
        capital stock, voting securities or securities convertible
        into or exchangeable for capital stock or voting securities
        of any Transferred Company; and (iv) except as otherwise
        indicated on the Schedule to this Section, there are no
        equity equivalents, interests in the ownership or earnings
        of any Transferred Company or other similar rights, other
        than the capital stock of the Transferred Companies.  A
        member of the Grace Group has the right to repurchase all
        the shares of the Transferred Companies not owned by the
        Selling Companies.  The outstanding capital stock of each
        such Transferred Company is duly authorized, validly
        issued, fully-paid and non-assessable and free of any
        preemptive rights in respect thereto, other than any such
        preemptive rights imposed by statutory law.  

                  (c)  The Schedule to this Section sets forth a
        complete list of all jurisdictions for which Dearborn U.S.
        is duly qualified or licensed to do business and Dearborn
        U.S. is in good standing in each of those jurisdictions. 
        Grace is the sole general partner in Dearborn U.S. and owns
        a 1% partnership interest.  LB Realty, a wholly owned
        Subsidiary of Grace, is the sole limited partner in
        Dearborn U.S. and owns a 99% partnership interest.  Grace
        and LB Realty each have good and valid title to the
        respective partnership interests owned by it.  The
        ownership of such partnership interests in each case is
        free and clear of all Liens.  There are (i) no outstanding
        subscriptions or other rights to purchase or otherwise
        acquire any partnership interest in Dearborn U.S., (ii) no
        securities of any of the Selling Companies or any of their
        affiliates (including, without limitation, the Transferred
        Companies) convertible into or exchangeable for any
        partnership interest in Dearborn U.S., (iii) no obligations
        of any of the Selling Companies or any of their affiliates
        (including, without limitation, the Transferred Companies)
        to issue, deliver or sell any partnership interest, voting
        securities or securities convertible into or exchangeable
        for partnership interests in Dearborn U.S. and (iv) no
        partnership interest equivalents, interests in the
        partnership of Dearborn U.S. or other similar rights. 
        Except as set forth in the Schedule to this Section, no
        Transferred Company owns or controls, directly or
        indirectly, any capital stock, or other securities of, or
        has any ownership interest in, any corporation, partnership
        or other entity.  

                  (d)  The Schedule to this Section sets forth a
        true and complete list of all dividends or other
        distributions declared or paid by any Transferred Company
        since December 31, 1995.

             5.3  Transferred Joint Ventures - Corporate Status and
        Capitalization.  Each Transferred Joint Venture is a
        corporation duly organized and validly existing under the
        laws of its jurisdiction of organization set forth in the
        Schedule to this Section.  The Schedule to this Section
        also sets forth a true and complete listing of the
        authorized, issued and outstanding capital stock of each
        Transferred Joint Venture and the ownership of such capital
        stock.  Except as set forth in the Schedule to this
        Section, (a) Grace and Dearborn Netherlands have good and
        valid title to the Dearborn India JV Shares and the
        Dearborn Japan JV Shares respectively in each case is free
        and clear of all Liens, (b) there are no outstanding

        Joint Venture, (c) there are no securities of the Selling
        Companies or any of their affiliates (including, without
        limitation, the Transferred Companies) convertible into or
        exchangeable for shares of capital stock or voting
        securities of any Transferred Joint Venture, and (d) there
        are no obligations of the Selling Companies or any of their
        affiliates (including, without limitation, the Transferred
        Companies) to issue, deliver or sell any capital stock,
        voting securities or securities convertible into or
        exchangeable for capital stock or voting securities of any
        Transferred Joint Venture.  The outstanding capital stock
        of each Transferred Joint Venture is validly issued, fully-
        paid and non-assessable.  The Schedule to this Section sets
        forth a true and complete list of all dividends declared or
        paid by each Transferred Joint Venture since December 31,
        1995.

             5.4  No Conflict.  Except as set forth on the Schedule
        to this Section, the execution and delivery of each
        Transaction Document by each member of the Grace Group that
        is or will be a party thereto, and the consummation of the
        transactions contemplated by such Transaction Document, do
        not and will not (a) contravene or conflict with the
        charter documents, by-laws or equivalent organizational
        documents of such member, (b) result in the breach or
        termination of, or constitute a default under (with or
        without the giving of notice or lapse of time or both) any
        agreement, contract or license binding upon any such member
        of the Grace Group, which breach, termination or default
        would have a Material Adverse Effect, or (c) result in
        breach of any of the provisions of, or constitute a default
        under, any judgment, order, decree, law or regulation, to
        which any such member is a party or by which it is bound,
        which breach or default would materially adversely affect
        the ability of such member to execute and deliver this
        Agreement or any other Transaction Document to which it is
        or will be a party or to perform its obligations hereunder
        or thereunder.

             5.5  Absence of Title Claims.

                  (a)  Except with respect to Real Property (as
        defined in subsection (b) of this Section) and as specified
        in the Schedule to this Section, neither the Total Dearborn
        Assets nor the assets of any of the Transferred Companies
        are subject to any Lien, covenant, restriction, easement or
        other such encumbrance, other than those Liens, covenants,
        restrictions, easements, and encumbrances that would not,
        individually or in the aggregate, have a Material Adverse
        Effect.  The material owned tangible assets are in good
        condition and, if applicable, in good working order, other
        than with respect to such assets as to which the failure to
        be in good working order or condition would not have a
        Material Adverse Effect.  The Selling Companies and their
        affiliates have complete and unrestricted power and the
        unqualified right to sell, assign and transfer to the
        Buying Companies all of the Total Dearborn Assets owned by
        them, and upon consummation of the transactions
        contemplated by this Agreement, the Buying Companies will
        acquire or the Transferred Companies will have good, valid
        and marketable title to the Total Dearborn Assets, free and
        clear of all Liens, except for Liens which individually or
        in the aggregate would not have a Material Adverse Effect. 
        The bills of sale, deeds, endorsements, assignments and
        other instruments to be executed and delivered to Buyer by
        the Selling Companies at the Closing will be valid and
        binding obligations of the Selling Companies enforceable in
        accordance with their terms. 

                  (b)  To the Knowledge of the Executives (except
        with respect to Real Property) there are no other defects
        in any Selling Company's title to any of the Total Dearborn
        Assets or in the title of the Transferred Companies to
        their respective assets that would, individually or in the
        aggregate, have a Material Adverse Effect.

                  (c)  Schedule 5.5(c) sets forth (i) a complete
        and correct list of all of the real property owned by Grace
        or its affiliates which is included in the Total Dearborn
        Assets and all of the real property owned by the
        Transferred Companies (the "Owned Real Property") and (ii)
        a list of all material real property leased by Grace or its
        affiliates which is included in the Total Dearborn Assets
        and a list of all material real property leased by the
        Transferred Companies (the "Leased Real Property", and
        together with the Owned Real Property, the "Real
        Property").  Except as specified in the Schedule to this
        Section, each Selling Company or Transferred Company, as
        the case may be, has good, valid and insurable (to the
        extent insurance is available in the jurisdiction) title to
        the Owned Real Property, or a valid leasehold interest in
        the Leased Real Property, in each case, free of all Liens,
        covenants, restrictions, easements or other such
        encumbrances which would materially interfere with the
        continued use or operation of such Owned Real Property or
        Leased Real Property in the manner heretofore used or
        operated by the Grace Group in its conduct of the Dearborn
        Business.

                  (d)  To the Knowledge of the Executives, neither
        the Selling Companies nor the Transferred Companies has
        received any written notice or communication from a
        Governmental Authority advising it of any (i) general or
        special assessment relating to any of the Real Property or
        (ii) condemnation or eminent domain proceedings pending or
        threatened against any of the Real Property, that would
        have a Material Adverse Effect.

             5.6  Financial Statements.  As of the Closing, the
        Schedule to this Section will contain copies of the 1995
        Dearborn Statement of Net Assets and the 1995 Dearborn
        Statement of Pretax Income, both audited by Price
        Waterhouse, and Price Waterhouse's reports thereon.  Such
        statements are referred to collectively as the "Dearborn

        Dearborn Statement of Net Assets will present fairly, in
        all material respects, the net assets of the Dearborn
        Business, as of December 31, 1995, in accordance with the
        terms of this Agreement, as described in Note 1 thereto, in
        conformity with U.S. GAAP and the 1995 Dearborn Statement
        of Pretax Income (which will include a line item identified
        as Contribution Margin determined in accordance with
        Dearborn Business practice) will present fairly, in all
        material respects, the pretax results of operations of the
        Dearborn Business for 1995, on the basis of presentation
        described in Note 1 thereto, in conformity with U.S. GAAP;
        provided, however, that the Dearborn Financial Statements
        will not be a complete presentation of the Dearborn
        Business's financial condition and results of operations as
        if it were a separate stand-alone operation.

                  (c)  There is no default with respect to any
        provision contained in any such insurance coverage; and
        there has not been any failure to give any notice or
        present any claim under any such insurance coverage in a
        timely fashion or in the manner of detail required by any
        such insurance coverage, except for any such failures,
        terminations, cancellations, reservations or defaults,
        which, individually or in the aggregate, would not
        reasonably be expected to have a Material Adverse Effect.

             5.11 Contracts.

        there exists no event of default or occurrence or act on
        the part of the Selling Companies or any of their
        affiliates or on the part of the other parties to the
        Material Contracts which constitutes or would constitute
        (with notice or lapse of time or both) a breach or default
        under any of the Material Contracts.

                  (e)  None of the Selling Companies or the

        covered by an individual (non-standard) written employment
        agreement that will remain in effect after the Closing. 
        Grace has heretofore delivered or made available to Buyer
        complete copies of all such agreements as currently in

        lockout relating to labor or employment matters pending or,
        to the Knowledge of the Executives, threatened against or
        affecting the Dearborn Business, except where such strike,
        slowdown, work stoppage or lockout would not reasonably be
        expected to have a Material Adverse Effect, (ii) there is
        no unfair labor practice, charge or other proceeding
        involving the Dearborn Business pending, or, to the
        Knowledge of the Executives, threatened before the National
        Labor Relations Board and (iii) the Executives do not have
        any Knowledge of any current union organizing activities
        among employees of Grace or any of its affiliates with
        respect to the Dearborn Business.  The Transferred
        Companies are in compliance with the requirements of the
        Worker Adjustment and Retraining Notification Act ("WARN")

        written employee benefit plan that provides retirement,
        pension, severance, health care, long-term disability
        income or life insurance benefits (other than plans
        maintained or required by applicable law or Governmental
        Authorities, which are hereinafter sometimes referred to
        collectively as "Governmental Plans"), that as of the date
        hereof covers any Dearborn Business Employee in Argentina,
        Australia, Belgium, Brazil, Canada, Chile, France, Germany,
        the Netherlands, South Africa, Sweden, the United Kingdom
        or the United States, and each written employee benefit
        plan or contract currently maintained by any Transferred
        Company that provides such benefit coverages, other than
        Governmental Plans.  Grace has heretofore delivered or made
        available to Buyer true and complete copies of all such
        plans that are administered by the Grace Group, and all
        such contracts to which any Transferred Company is a party,
        as currently in effect.

                  (b)  Except as listed on the Schedule to this
        Section, with respect to each Seller Plan from which any
        assets are transferred to any Buyer Plan or which is
        assumed by the Buyer Group (each such plan, a "Transferred
        Plan"):  (i) no Transferred Plan is subject to Title IV of
        the Employee Retirement Income Security Act of 1974; (ii)
        each Transferred Plan (except for a Transferred Plan
        described in Section 5.13(b)(iii)) has been operated and
        administered in all material respects in accordance with
        its terms and applicable law, except to the extent
        otherwise disclosed to the Buyer Group by the Grace Group
        prior to the date of the transfer of assets from, or the
        assumption of, such Transferred Plan; and (iii) with
        respect to a Transferred Plan maintained in a jurisdiction
        where applicable law requires that the Buyer Group (or a
        plan maintained by the Buyer Group) assume any portion of
        the assets and/or liabilities of such Transferred Plan,
        each such Transferred Plan has been operated and
        administered in all material respects in accordance with
        its terms and applicable law.

                  (c)  The consummation of the transactions
        contemplated by this Agreement will not:  (i) entitle any
        current or former Dearborn Business employee or officer to
        receive from Buyer or any Buyer Plan any severance pay,
        unemployment compensation or any other similar payment, as
        a result of the terms of any plan or arrangement maintained
        by the Grace Group or (ii) accelerate the time of payment
        or vesting, or increase the amount, of compensation due any
        such employee or officer from the Buyer Group, as a result
        of the terms of any plan or arrangement maintained by the
        Grace Group; except as set forth by this Agreement and in
        the Employee Benefits Agreement.

             5.14 Environmental Compliance.

                  (a)  Except as set forth on Schedule 5.14, none
        of the real property currently, or to the Knowledge of the
        Executives, formerly, owned or operated by the Dearborn
        Business is listed on the federal National Priorities List
        ("NPL") or on lists of properties requiring investigation
        or cleanup that have been compiled pursuant to state or
        foreign laws that are analogous to CERCLA.

                  (b)  Except as set forth on Schedule 5.14, to the
        Knowledge of the Executives:

                       (i)  The Dearborn Business is in compliance
        with all applicable Environmental Laws, including having
        obtained all material permits, licenses and authorizations
        which are required under such laws ("Environmental
        Authorizations"), except where the failure to so comply
        with such Environmental Laws, individually or in the
        aggregate, would not reasonably be expected to have a
        Material Adverse Effect.  All such Environmental
        Authorizations are in effect, no appeal nor any other
        action is pending to revoke any such Environmental
        Authorization, and the Dearborn Business is in full
        compliance with all terms and conditions of such
        Environmental Authorizations, except where the failure to
        comply with such Environmental Authorizations, or the
        existence of any appeal or action to revoke such
        Environmental Authorizations, would not reasonably be
        expected to have, individually or in the aggregate, a
        Material Adverse Effect.

                       (ii) Neither Grace nor the Dearborn Business
        has received written notice from any third party,
        including, but not limited to, any Governmental Authority,
        alleging a Toxic Tort Claim or Chromium Claim or that the
        Dearborn Business or the Total Dearborn Assets are in
        violation of any applicable Environmental Law or otherwise
        liable under any applicable Environmental Law, which claim,
        violation or liability is unresolved.  There is no pending
        or threatened Toxic Tort Claim or Chromium Claim or claim,
        lawsuit, or administrative proceeding under any
        Environmental Law against the Dearborn Business or the
        Total Dearborn Assets. 

                       (iii) There is no pending or threatened
        Toxic Tort Claim or Chromium Claim or claim, lawsuit, or
        administrative proceeding under any Environmental Law
        against any Person whose liability has been either retained
        or assumed contractually by the Dearborn Business.

                       (iv) There have been no releases, spills, or
        discharges of Hazardous Substances on or underneath any of
        the real property currently or formerly owned or operated
        by the Dearborn Business that would reasonably be expected
        to have a Material Adverse Effect.

                  (a)  Schedule 5.15(a) sets forth a true and
        complete list of all Scheduled Intellectual Property that

                  (b)  Except as set forth in Schedule 5.15(b), or
        to the extent that the inaccuracy of any of the following

        Effect:

                            assigned or licensed to Buyer include
                            all intellectual property rights which
                            (1) are necessary to or are used in the

                            development for use in the Dearborn
                            Business.

                       (ii) the Selling Companies and the
                            Transferred Companies, as the case may
                            be, own or are authorized to use, in

                             subparagraph (3) of Section (A) of the
                             definition of Intellectual Property
                             Rights), and to the Knowledge of the
                             Executives, have good and unencumbered

                             Intellectual Property");

                       (iv) there is no Lien on the right of the
                            Selling Companies to transfer to Buyer
                            any of the Intellectual Property Rights
                            listed in Section (A) of the definition
                            of Intellectual Property Rights, or to
                            grant licenses to the Intellectual
                            Property Rights described in Section

                            contemplated, other than any such Liens
                            that alone or in the aggregate would
                            not result in a Material Adverse

                            with the legal and administrative
                            requirements of the appropriate
                            jurisdictions except with respect to

                       (ii) the current operation of the Dearborn
                            Business does not infringe upon or,

                       (iii) no third party unrelated to the Grace
                             Group is infringing upon or, with
                             respect to trade secrets, is otherwise
                             violating any Intellectual Property
                             Rights;

                       (iv) none of the Selling Companies or any of
                            their respective affiliates has
                            received notice of any claims and there
                            are no pending claims by any Person
                            relating to the ownership or use of the
                            Intellectual Property Rights.

                  (c)  Schedule 5.15(c) sets forth a true and
        complete list of all Intellectual Property Licenses. 
        Except as set forth on Schedule 5.15(c), no Person that is
        not a member of the Grace Group has been granted any right
        or license to use any Intellectual Property Rights by any
        Selling Company or Transferred Company.

                  (d)  Schedule 5.15(d) sets forth a true and
        complete list of all agreements between any Selling Company
        or Transferred Company, on the one hand, and any Person on
        the other, which (i) is not listed on Schedule 5.15(c); and
        (ii) conveys rights under Scheduled Intellectual Property
        or Non-Scheduled Intellectual Property to any Person that
        is not a member of the Grace Group, or grants rights under
        any intellectual property owned by any such Person that is
        directly and exclusively used in the Dearborn Business. 
        Grace has heretofore delivered or made available to Buyer
        true and complete copies of such agreements as are in
        effect.

             5.16 Non-Environmental Licenses and Permits.

             Except as set forth in the Schedule to this Section,
        and specifically excluding all environmental matters:

                  (a)  (i)  The Selling Companies and the
        Transferred Companies have obtained or have duly applied
        for all material permits, licenses or other governmental
        authorizations to conduct the Dearborn Business, as it is
        currently conducted, and (ii) to the Knowledge of the
        Executives, such permits and licenses are valid, subsisting
        in full force and effect, and each of the Selling Companies
        and the Transferred Companies has fulfilled its obligations
        under such permits and licenses, and (iii) no event has
        occurred which constitutes or, after notice, or lapse of
        time, or both, would constitute a default or violation
        under such permits or licenses or would permit revocation
        or termination of any such permits or licenses, other than
        any such default, violation, revocation, or termination
        that individually or in the aggregate would not reasonably
        be expected to have a Material Adverse Effect.

                  (b)  Since December 31, 1995, no written warning
        notice, notice of violation or probable violation, notice
        of revocation, or other written communication from or on
        behalf of any Governmental Authority has been received by
        any Selling Company or Transferred Company, which violation
        has not been corrected or situation otherwise settled,
        alleging (i) any violation of any such permit, license or
        authorization, or (ii) that any Selling Company or
        Transferred Company requires any such license, permit or
        authorization for the Dearborn Business not currently held
        by them.

                  (c)  No Selling Company or Transferred Company is
        in violation of, or has violated, in any such case directly
        in connection with the conduct of the Dearborn Business,
        any applicable provisions of any laws, rules, statutes,
        orders, ordinances or regulations which, individually or in
        the aggregate, has resulted or would reasonably be expected
        to result in a Material Adverse Effect.

                  (d)  Except as set forth on the Schedule to this
        Section, neither the Selling Companies nor any of their
        affiliates (including, without limitation, the Transferred
        Companies) is in violation of, or has violated, in any such
        case in connection with the conduct of the Dearborn
        Business, any applicable provisions of any laws, rules,
        statutes, orders, ordinances or regulations which,
        individually or in the aggregate, has resulted or would
        reasonably be expected to result in a Material Adverse
        Effect. 

             5.17 Brokers and Finders.  No broker or finder has
        acted directly or indirectly for Grace or any of the other
        Selling Companies in connection with this Agreement or the

        Pierce Fenner & Smith Incorporated whose fees and expenses
        will be paid by Grace.

        extent set forth in the 1995 Dearborn Statement of Net
        Assets, or the notes thereto, neither the Selling Companies
        nor the Transferred Companies had at December 31, 1995 any
        liabilities (absolute, accrued, contingent or otherwise,
        known or unknown) relating to the Dearborn Business which
        are required by the U.S. GAAP to be reflected in a
        consolidated balance sheet or set forth in the notes

        liabilities (absolute, accrued, contingent or otherwise,
        known or unknown) relating to the Dearborn Business and
        required by U.S. GAAP to be reflected on a consolidated
        balance sheet except for liabilities incurred in the
        ordinary course of business since December 31, 1995 which
        would not individually or in the aggregate, be reasonably
        expected to have a Material Adverse Effect.

             5.19 Assets Necessary for Conduct of the Dearborn
        Business.  The assets to be transferred to the Buying
        Companies pursuant to this Agreement or made available to
        the Buying Companies pursuant to the Ancillary Agreements
        constitute all of the assets necessary to conduct the
        production, logistics, marketing, sales and laboratory
        (research, applications and customer service) functions of
        the Dearborn Business, as currently conducted and are all
        of the assets used with respect to such functions in the
        Dearborn Business as currently conducted.

             5.20 Accounts Receivable.  All accounts receivable
        included in the Total Dearborn Assets and all accounts
        receivable of the Transferred Companies represent unpaid
        actual billings for sales made in the ordinary course of
        business and represent the legal, valid and binding
        obligations of the obligor thereon or adequate reserves
        have been established for those accounts receivable which
        are not valid and binding or are otherwise uncollectible. 
        The Dearborn Financial Statements contain adequate and
        sufficient reserves for bad debts in respect of accounts
        receivable of the Dearborn Business.

             5.21 Inventory.  All of the inventories included in
        the Total Dearborn Assets and all inventories of the

        adequate reserves for obsolete or below standard quality
        materials have been provided therefor.  Inventories of the
        Dearborn Business are valued in the Dearborn Financial
        Statements at the lower of cost or market.

             5.22 Disclosure.  To the Knowledge of the Executives,
        no representation or warranty of any of the Selling
        Companies contained in this Agreement, in written
        certificates delivered pursuant to this Agreement or in any

        Schedules attached hereto or thereto) contains any untrue
        statement of material fact or omits to state any material
        fact necessary, in order to make the statements made herein
        or therein, in light of the circumstances under which they
        were made, not misleading.

             5.23 Other Matters.  The Dearborn Business has no
        liability or responsibility with respect to any personal
        injury or property damage claims that have been brought
        against Grace or any Subsidiary of Grace relating to the
        sale of asbestos-containing products.

                                 ARTICLE 6
                         REPRESENTATIONS OF BUYER

             Buyer represents and warrants to Grace and the other
        Selling Companies as follows:

             6.1  Buying Companies' Corporate Status.  Buyer is a
        corporation duly organized, validly existing and in good
        standing under the laws of its jurisdiction of
        organization.  Each Buying Company (other than Buyer) is a
        direct or indirect subsidiary of Buyer.  Each member of the
        Buyer Group that is a party to this Agreement or one of the
        other Transaction Documents has full legal power to execute
        and deliver each Transaction Document to which it is or
        will be a party, and will, prior to the Closing, have full
        legal power to perform its obligations under such
        Transaction Document and to consummate the transactions
        contemplated thereby.  The execution and delivery by each
        member of the Buyer Group of each Transaction Document to
        which it is or will be a party, its performance of its
        obligations under such Transaction Document and the
        consummation of the transactions contemplated thereby, will
        prior to the Closing have been duly authorized by all
        required corporate action of such member.  Each such member
        of the Buyer Group has duly and validly executed and
        delivered each Transaction Document to which it is a party
        that is being executed and delivered simultaneously with
        this Agreement, and each such Transaction Document
        constitutes a legal, valid and binding obligation of such
        member, enforceable against such member in accordance with
        its terms.  Each Transaction Document to be executed by any
        member of the Buyer Group at the Closing, when executed and
        delivered, will be duly and validly executed and delivered
        by, and will constitute a legal, valid and binding
        obligation of such member and be enforceable against such
        member in accordance with its terms.

             6.2  No Conflict.  Except as set forth on the Schedule
        to this Section, the execution and delivery of each
        Transaction Document by each member of the Buyer Group that
        is or will be a party thereto, and the consummation of the
        transactions contemplated by such Transaction Document, do
        not and will not (a) contravene or conflict with the
        charter documents, by-laws or equivalent organizational
        documents of such member, (b) result in the breach or
        termination of, or constitute a default under (with or
        without the giving of notice or lapse of time or both) any
        agreement, contract or license binding upon any such member
        of the Buyer Group which breach, termination or default
        would have a Material Adverse Effect, or (c) result in
        breach of any of the provisions of, or constitute a default
        under, any judgment, order, decree, to which it is a party
        or by which it is bound, which breach or default would
        materially adversely affect the ability of such member to
        execute and deliver this Agreement or any other Transaction
        Document to which it is or will be a party or to perform
        its obligations hereunder or thereunder.

             6.3  Sufficient Funds.  On the Closing Date, the
        Buying Companies will have sufficient funds to consummate
        the transactions contemplated by this Agreement.

             6.4  Brokers and Finders.  No broker or finder has
        acted directly or indirectly for Buyer or any of its
        affiliates in connection with this Agreement or the
        transactions contemplated hereby, except for J.P. Morgan &
        Co., whose fees and expenses will be paid by Buyer.

                                 ARTICLE 7
                   INVESTIGATION BY THE BUYING COMPANIES

             Buyer acknowledges the following:

             7.1  Investigation.  The Buying Companies have
        conducted their own investigation and made their own
        evaluation of the Dearborn Business, the Transferred
        Companies, the Transferred Joint Ventures, the Total
        Dearborn Assets and the Total Dearborn Liabilities. 

             7.2  Financial Information.  As part of their
        investigation, the Buying Companies have been given
        financial statements, forecasts, projections, opinions and
        other oral or written information and materials with
        respect to the Dearborn Business (the "Additional Financial
        Information") by Grace, other members of the Grace Group or
        their respective representatives.  There are uncertainties
        inherent in attempting to make projections and forecasts,
        and the Buying Companies are familiar with such
        uncertainties.  The Buying Companies have made their own
        evaluation of the Additional Financial Information. 
        Neither Grace nor any other member of the Grace Group is
        making any representations or warranties with respect to
        the Additional Financial Information or the Dearborn
        Financial Statements except for the specific
        representations and warranties set forth in Article 5. 

             7.3  No Additional Representations.  Except for the
        specific representations and warranties set forth in this
        Agreement, including the Schedules hereto, the Ancillary
        Agreements or any certificate contemplated hereby and
        delivered to Buyer in connection herewith, none of the
        Selling Companies (nor any other member or affiliate of the
        Grace Group ) is making any representation or warranty,
        express or implied, of any nature whatsoever.

                                 ARTICLE 8
                    COVENANTS OF THE SELLING COMPANIES
                         AND THE BUYING COMPANIES

             8.1  Access and Inquiry.  Between the date of this
        Agreement and the Closing, the Selling Companies shall
        provide, and shall cause the Transferred Companies (and, to
        the extent Grace has the right to do so, the Transferred
        Joint Ventures) to provide, to the Buying Companies and
        their counsel, financial advisors, auditors and other
        representatives, reasonable access to the properties and
        facilities of the Dearborn Business (including reasonable
        access to enable Buyer to conduct Phase I environmental
        investigations, but not Phase II environmental
        investigations or other testing that may include invasive
        procedures such as soil core borings or testing of
        environmental media), and will, upon written request,
        permit the Buying Companies and their counsel, financial
        advisors, auditors and other representatives to contact and
        make reasonable inquiry of employees of the Selling
        Companies and the Transferred Companies (and, to the extent
        Grace is able to arrange for such access and inquiry, to
        the facilities and employees of the Transferred Joint
        Ventures) regarding the Dearborn Business.  Except for the
        details of any trade secrets and other sensitive
        intellectual property, the Selling Companies shall, and
        shall cause the Transferred Companies (and, to the extent
        Grace has the right to do so, the Transferred Joint
        Ventures) to, make available to the Buying Companies all
        books, records, and other financial data and files, where
        located, of the Selling Companies, the Transferred
        Companies and the Transferred Joint Ventures relating
        primarily to the Dearborn Business, to the extent
        reasonably requested by any Buying Company.  The Buying
        Companies acknowledge that the terms of the confidentiality
        agreement dated November 15, 1995 between Grace and Buyer
        (the "Confidentiality Agreement") shall apply to
        information obtained by any Buying Company pursuant to the
        foregoing.

             8.2  Hart-Scott and Other Filings.  As promptly as
        practicable after the date hereof, Grace and Buyer shall
        file or cause to be filed with respect to this Agreement
        and the transactions contemplated hereby appropriate
        Notification and Report Forms under the HSR Act and filings
        with Governmental Authorities in other jurisdictions under
        similar statutes or foreign investment statutes.  Grace and
        Buyer shall cooperate to coordinate such filings, and to
        make reasonable efforts to promptly respond to any request
        or inquiry by a Governmental Authority with respect
        thereto.  Each party will furnish to the other party such
        information and reasonable assistance as such other party
        may reasonably request in connection with the foregoing.

             8.3  Intentionally Omitted.

             8.4  Notices to Third Parties.

                  (a)  The Buying Companies and the Selling
        Companies shall use their reasonable best efforts to take
        or cause to be taken all action, to do or cause to be done,
        and to assist and cooperate with the other parties hereto
        in doing all things necessary, proper or advisable to
        consummate and make effective, in the most expeditious
        manner practicable, the transactions contemplated by this
        Agreement.  Without limiting the generality of the
        foregoing, the parties hereto shall cooperate with one
        another:  (i) in determining whether action by or in
        respect of, or filing with, any Governmental Authority
        (either domestic or foreign) is required, proper or
        advisable or any actions, consents, waivers or approvals
        are required to be obtained from parties to any contracts,
        in connection with the transactions contemplated by this
        Agreement; (ii) in seeking to obtain any such actions,
        consents and waivers and to make any such filings; and
        (iii) in negotiating alternative arrangements in the event
        a governmental or third party (including, without
        limitation, a labor union or works council) consent,
        permit, authorization or registration required pursuant to
        the transactions contemplated hereby is not obtained on a
        timely basis or in the event Buyer is unable to make
        necessary arrangements to establish a buying entity in a
        certain jurisdiction, with the understanding that such
        arrangements will be designed so as to put the parties in a
        position as close as practicable to that which they would
        have been in had such consent, permit, authorization,
        registration or action been obtained including, without
        limitation, providing to such party the benefits and
        liabilities associated with the ownership and operation of
        any assets subject to such consent, permit, authorization,
        registration or action.  Notwithstanding the foregoing, the
        provisions of this Section shall not apply to any matters
        covered by the provisions of Section 2.5 hereof, which
        matters shall continue to be covered by Section 2.5.  In
        case at any time after the Closing any further action is
        necessary or desirable to carry out the purposes of this
        Agreement, the proper officers and directors of each party
        hereto shall promptly take all such necessary action.

                  (b)  To the extent any party shall reasonably
        request, the parties shall prepare and execute, with the
        assistance and advice of local counsel, additional
        agreements reflecting the fundamental terms of this
        Agreement to the extent required by local laws in order to
        effectuate the transactions contemplated by this Agreement. 
        Notwithstanding the foregoing, the parties agree that this
        Agreement sets forth the complete agreement and
        understanding of the parties with respect to the matters
        set forth herein and, to the fullest extent permitted by
        law, shall be controlling in the event of any conflict or
        inconsistency between the provisions hereof and the
        provisions of any of such local agreements.

             8.5  Reorganization of Dearborn Business in Brazil and
        Sweden.  Prior to the Closing, (a) Grace shall cause Grace
        Brazil to transfer to Holdings Brazil the assets and
        liabilities of the Dearborn Business described in Part I of
        the Schedule to this Section in exchange for shares of the
        capital stock of Grace Brazil owned by Holdings Brazil, and
        (b) Grace shall cause Grace Sweden to transfer to Dearborn
        Sweden as a capital contribution the assets and liabilities
        described in Part II of the Schedule to this Section and
        thereafter, Grace shall cause the Swedish Holding Company
        to purchase the Dearborn Sweden Shares from Grace Sweden. 
        All costs and expenses incurred by Grace or its affiliates
        in connection with the reorganization referred to above
        shall be the obligation of Grace and shall not be paid by
        Buyer or its affiliates.

             8.6  Reasonable Best Efforts.  In making its
        reasonable best efforts under Sections 8.2 and 8.4, except
        as may be contemplated by Section 2.5, no member of the
        Grace Group or the Buyer Group shall be required to make
        any payment (other than for reasonable legal fees and
        routine filing fees) that it is not presently contractually
        required to make, divest any assets (including, but not
        limited to, assets of the Dearborn Business), make any
        change in the conduct of its business or that of the
        Dearborn Business, accept any limitation on the future
        conduct of its business or that of the Dearborn Business,
        enter into any other agreement or arrangement with any
        Person that it is not presently contractually required to
        enter into, accept any significant modification of any
        existing agreement or arrangement, or agree to any of the
        foregoing.

             8.7  Intentionally Omitted.

             8.8  Covenant Not to Compete; No Solicitation.

                  (a)  For a period of five years after the Closing
        Date, the Selling Companies shall not, and shall cause
        their affiliates not to, directly or indirectly:  (i)
        engage in the Dearborn Business in those countries where
        the Dearborn Business currently operates, or in the
        development, registration, formulation, sale or
        distribution of any products primarily directed to a market
        that competes with the Dearborn Business as currently
        conducted including, without limitation, products that are
        the result of discoveries or development by the Grace Group
        after the Closing Date or (ii) invest in, manage, operate,
        join or control as a partner, stockholder, consultant or
        otherwise, any Person that competes with the Dearborn
        Business in any jurisdiction where the Dearborn Business is
        currently conducted (a "Buyer Competitive Business");
        provided, however, that nothing in this Section 8.8 shall
        prohibit the Selling Companies, or their affiliates, from
        owning up to 5% of the outstanding voting securities of any
        publicly traded entity; provided, further, that nothing in
        this Section 8.8 shall prohibit the Selling Companies, or
        their affiliates, from acquiring a Buyer Competitive
        Business as an incidental part of an acquisition (by joint
        venture, merger or other) of the assets of, or the majority
        of voting interests in, another Person (a "Target
        Business") if the worldwide sales of the Target Business
        from the Buyer Competitive Business are not in excess of
        30% of the worldwide sales of the Target Business in the
        fiscal year of the Target Business, for reporting purposes,
        preceding such acquisition.  In the event the Selling
        Companies, or their affiliates, acquire a Buyer Competitive
        Business pursuant to the second proviso in the preceding
        sentence and the worldwide sales of the Buyer Competitive
        Business are either in excess of 10% of the worldwide sales
        of the Target Business or in excess of US $50 million in
        such fiscal year, the Selling Companies shall thereafter
        divest such Buyer Competitive Business within a reasonable
        period of time by way of auction or other competitive
        bidding process, negotiation, sale or such other manner or
        divestiture as the Selling Companies shall deem
        appropriate.

                  (b)  For a period of two years after the Closing
        Date, the Selling Companies shall not, and shall cause
        their affiliates not to, solicit to employ any of the
        employees of the Dearborn Business so long as they are
        employed by the Dearborn Business.

                  (c)  If any provisions contained in this Section
        shall for any reason be held invalid, illegal or
        unenforceable in any respect, such invalidity, illegality
        or unenforceability shall not affect any other provisions
        of this Section, but this Section shall be construed as if
        such invalid, illegal or unenforceable provisions had never
        been contained herein.  It is the intention of the parties
        that if any of the restrictions or covenants contained
        herein is held to cover a geographic area or to be for a
        length of time which is not permitted by applicable law, or
        in any way construed to be too broad or to any extent
        invalid, such provision shall not be construed to be null,
        void and of no effect, but to the extent such provision
        would be valid or enforceable under applicable law, a court
        of competent jurisdiction shall construe and interpret or
        reform this Section to provide for a covenant having the
        maximum enforceable geographic area, time period and other
        provisions (not greater than those contained herein) as
        shall be valid and enforceable under such applicable law. 
        The Selling Companies agree that the Buying Companies shall
        be entitled, upon a proper showing, to injunctive relief
        requiring specific performance of this Section by the
        Selling Companies.

             8.9  Notification of Certain Matters.  Grace shall use
        reasonable efforts to give prompt notice to Buyer, and
        Buyer shall use reasonable efforts to give prompt notice to
        Grace of any of the following events that occur between the
        date of this Agreement and the Closing as to which they
        obtain actual knowledge:  (a) the occurrence or non-
        occurrence of any event, the occurrence or non-occurrence
        of which would be reasonably likely to cause (i) any
        representation or warranty contained in this Agreement to
        be untrue or inaccurate in any material respect or (ii) any
        covenant, condition or agreement contained in this
        Agreement not to be complied with or satisfied in any
        material respect, and (b) any failure of the Selling
        Companies or the Buying Companies, as the case may be, to
        comply with or satisfy any covenant, condition or agreement
        to be complied with or satisfied by it hereunder in any
        material respect; provided, however, that the delivery of
        any notice pursuant to this Section 8.9 shall not limit or
        otherwise affect the remedies available hereunder to the
        party receiving such notice.  In addition, the Selling
        Companies will use reasonable efforts to promptly
        supplement or amend the Schedules with respect to any
        matter that they obtain actual knowledge of, hereafter
        arising which, if existing or occurring at the date of this
        Agreement, would have been required to be set forth or
        described in the attached Schedules.  No supplement or
        amendment of the attached Schedules made pursuant to this
        Section 8.9 shall be deemed to cure any breach of any
        representation or warranty made in this Agreement or limit
        in any way the purchase price adjustment set forth in
        Section 4.B.

             8.10 Resignations.  At the Closing, Grace will deliver
        to Buyer, the resignations (effective on or prior to the
        Closing Date) of all directors of the Transferred Companies
        whose resignations Buyer has requested, provided that Buyer
        has given Grace adequate time prior to the Closing Date to
        obtain the same.

             8.11 Confidentiality Agreements.  Grace hereby
        represents and warrants that it has entered into
        confidentiality agreements with certain third parties that
        expressed an interest in acquiring the Dearborn Business
        and that were subsequently permitted access to confidential
        information of the Dearborn Business and that each such
        agreement is now and will remain in full force and effect
        as of the date hereof and as of the Closing Date.  At the
        Closing, Grace shall assign such confidentiality agreements
        to Buyer.

             8.12 Work's Council.  Prior to the Closing, Grace
        shall provide to Buyer a schedule setting forth all
        jurisdictions in which the Dearborn Business is conducted
        in which a work's council is present.

        Person (other than representatives of Buyer) any trade

             12.1 Employees of Transferred Companies and

        job position and terms and conditions of employment of all
        active and inactive employees of the Transferred Companies

        benefit plans as otherwise may be provided in the Employee
        Benefits Agreement.

             12.2 Current, Continued and Transitional Service
        Employees.

                  (a)  On the Closing Date, the following
        individuals shall cease to be employees of the Grace Group:

        employed exclusively in the Dearborn Business, (ii) each
        employee of the Grace Group (other than the Transferred
        Companies or Transferred Joint Ventures) who performs

        designated by Grace as an employee who is to be transferred
        with the Dearborn Business, and (iii) each employee who
        replaces any employee described in clauses (i) and (ii). 
        All employees described in clauses (i) and (ii), as of

                  (b)  Each Current Employee (excluding any Current
        Employee who is on long-term disability on the Closing
        Date) who accepts an offer of employment made by a member
        of the Buyer Group in accordance with Section 12.3 shall
        become an employee of such member of the Buyer Group
        effective on the Closing Date; and all such Current

        for the Dearborn Business, cessation of each such
        employee's employment with the Grace Group shall be by
        mutual agreement between Buyer and Grace.  Any member of
        the Buyer Group may offer employment to any Transitional
        Services Employee to commence on or after the date such
        employee ceases to be an employee of the Grace Group.

             12.3 Positions Offered to Current Employees.

                  (a)  With respect to each Current Employee, the
        Buying Companies shall either offer the Current Employee
        employment with a member of the Buyer Group to commence on
        the Closing Date or the Current Employee shall be eligible
        for severance benefits as an employee described in Section
        12.6(a)(i).

                  (b)  With respect to each Current Employee who is

        offered by the Buying Companies:  (i) shall be for a job
        that is equivalent (including with respect to his or her

        to one that is an unreasonable commuting distance from his
        or her residence, and (iv) shall provide employee benefit
        plan coverages in accordance with the provisions of the
        Employee Benefits Agreement or (B) the position offered by
        the Buying Companies shall be on terms other than those set
        forth in (A) above, and, in such case, if the Current
        Employee does not accept that offer, he or she shall be
        eligible for severance benefits to the same extent as an
        employee described in Section 12.6(a)(ii) who voluntarily
        terminates employment with the Buyer Group.

                  (c)  The Selling Companies have not made any
        representation regarding which, if any, (i) Current
        Employees or Transitional Services Employees will accept
        offers of employment with the Buyer Group, or (ii)
        employees of the Transferred Companies and Transferred
        Joint Ventures will continue such employment after the
        Closing. 

             12.4 Employee Benefit Plans.  As of the Closing Date,
        the Continued Employees and the employees of the
        Transferred Companies and the Transferred Joint Ventures
        who participated in the employee benefit plans or
        arrangements maintained by the Grace Group shall cease to
        participate in those plans or arrangements and shall
        commence participation in employee benefit plans or
        arrangements established or maintained by the Buyer Group,
        in accordance with the Employee Benefits Agreement. 
        Notwithstanding the foregoing, the Grace Group and the
        Buyer Group may agree that certain such employees may
        continue to participate in employee benefit plans or
        arrangements maintained by the Grace Group for a specific
        period after the Closing Date.

             12.5 Vacation.  Effective as of the Closing Date, the
        Buyer Group shall assume all liability of the Grace Group
        with respect to vacation and leave of absence for each
        Continued Dearborn Business Employee.  With respect to each
        Continued Dearborn Business Employee who is credited with
        vacation and/or leave of absence earned on a calendar year
        basis, Buyer shall continue to apply the vacation and leave
        of absence policy and/or practice (whether or not legally
        required) applicable to such Continued Dearborn Business
        Employee the day before the Closing Date for at least the
        remainder of the calendar year in which the Closing occurs
        and the following calendar year; so that each such
        Continued Dearborn Business Employee shall be entitled to
        use any vacation days or leave of absence time, and/or
        receive any pay related thereto, to which he or she would
        otherwise be entitled for such calendar years applicable
        the day before the Closing Date.  With respect to any
        Continued Dearborn Business Employee who is credited with
        vacation days or leave of absence time (and pay related
        thereto) based on the 12-month period commencing on his or
        her employment anniversary date (an "Anniversary Vacation
        Period"), and not based on a calendar year, Buyer shall
        continue to apply the vacation and leave of absence policy
        and/or practice (whether or not legally required)
        applicable to such Continued Dearborn Business Employee the
        day before the Closing for least the Anniversary Vacation
        Period during which the Closing occurs and the following
        Anniversary Vacation Period; so that each such Continued
        Dearborn Business Employee shall be entitled to use any
        vacation days or leave of absence time, and/or receive any
        pay related thereto, to which he or she would otherwise be
        entitled for such Anniversary Vacation Period(s) applicable
        the day before the Closing Date.

             12.6 Severance Arrangements.

                  (a)  Buyer acknowledges that:

                       (i)  a severance and retention arrangement
        has been adopted by the Grace Group (the "Grace Severance
        Arrangement"), as described on the Schedule to this Section
        that provides severance pay and other benefits to each
        Dearborn Business Employee (except for an employee of any
        Transferred Joint Venture) who is deemed by Grace to be a
        regular salaried employee of the Grace Group (a "Salaried
        Dearborn Business Employee") and who Grace determines has
        become unemployed as of the Closing Date; or who Grace
        determines has been terminated as of an earlier date as a
        direct result of the divestment of the Dearborn Business,
        but only if consented to by Buyer. 

                       (ii) the severance and other benefits under
        the Grace Severance Arrangement shall also apply to each
        Salaried Dearborn Business Employee who:  (A) becomes an
        employee of the Buyer Group but who is subsequently
        involuntarily terminated from employment with the Buyer
        Group within 6 months after the Closing Date due to plant
        consolidation, closing or relocation, or other
        circumstances that are not directly related to the
        employee's performance, (B) becomes an employee of the
        Buyer Group but voluntarily terminates his or her
        employment within 6 months after the Closing Date as a
        result of an unreasonable change in job duties, a decrease
        in compensation or a change in work location that results
        in an unreasonable commuting distance from the employee's
        existing residence, or (C) on the Closing Date or on any
        date subsequent thereto is absent from work due to
        disability or leave of absence (whether or not he or she is
        receiving workers' compensation payments), and who recovers
        from such disability and requests reinstatement to active
        employment status within 6 months of the Closing Date, but
        is denied reinstatement by any member of the Buyer Group;

                       (iii) certain Dearborn Business Employees
        who are not eligible for severance under the Grace
        Severance Arrangement may be entitled to severance benefits
        under local law as a result of the transactions
        contemplated by this Agreement, even if they commence
        employment with the Buyer Group, refuse to accept an offer
        of employment with the Buyer Group or resign their
        employment with the Grace Group; and

                       (iv) Transitional Services Employees shall
        be eligible for severance under various plans, programs,
        policies and practices of the Grace Group upon termination
        of employment with the Grace Group (but shall not be
        eligible to participate in the Grace Severance
        Arrangement).

                  (b)  Buyer shall reimburse Grace (or any other
        member of the Grace Group designated by Grace) for the cost
        incurred in connection with severance pay and/or other
        severance benefits (i) under the Grace Severance
        Arrangement with respect to Dearborn Business Employees who
        become entitled to severance benefits under circumstances
        described in Section 12.3(a) or (b) or Section 12.6(a)(i)
        or (ii), and (ii) under any local law that requires
        severance to be paid to Dearborn Business Employees as a
        result of the transactions contemplated by this Agreement
        (as described above in Section 12.6(a)(iii)).  Buyer shall
        make such reimbursement due pursuant to this Section
        12.6(b) within 30 days after receipt of a written demand
        from Grace specifying the amount of the costs incurred
        during a specific period and appropriate supporting
        documentation.

                  (c)  Buyer shall pay Grace (and/or other members
        of the Grace Group designated by Grace) a total of US
        $10,000,000 in a manner described in the transitional
        services agreement(s) that shall be entered into between
        the Grace Group and the Buyer Group, which shall be
        regarded as compensation for severance benefits that will
        be (or may be) provided by the Grace Group under any plan,
        program, policy or practice of the Grace Group to
        Transitional Services Employees who are terminated by the
        Grace Group.  With respect to any Transitional Services
        Employee who is to be terminated by the Grace Group but who
        is transferred to, or hired by, the Buyer Group, then the
        Grace Group shall credit to Buyer (or any other member of
        the Buyer Group designated by Buyer) an amount equal to the
        cost of the severance benefits that would have been
        provided to such employee if the employee was terminated by
        the Grace Group and not transferred to, or hired by, the
        Buyer Group; but only if under applicable law the Grace
        Group is not required to provide severance benefits to such
        employee.

             12.7 Post-Closing Severance Benefits For Salaried
        Dearborn Business Employees.

                  (a)  Effective 6 months after the Closing Date,
        Buyer shall cause each Salaried Dearborn Business Employee
        then employed by the Buyer Group to be covered by a
        severance plan or program that shall remain in effect for a
        period of not less than 18 months thereafter (the "Buyer's
        Severance Arrangement").  The Buyer's Severance Arrangement
        shall provide for the following:  (i) severance payments
        equal to the payments that such employees would have been
        entitled to under the terms of the Grace Severance
        Arrangement, based upon an aggregation of service with the
        Grace Group up to the Closing Date and service with the
        Buyer Group on and after the Closing Date, (ii) payments
        for unused but accrued vacation as of the date of the
        employee's termination, (iii) outplacement services and
        (iv) with respect to a Salaried Dearborn Business Employee
        who is employed in the United States, continuation of
        coverage under the Buyer's Medical Plans (as defined in the
        Employee Benefits Agreement) for the shortest of the
        following periods:  (i) the period ending 4 months after
        the employee's last date of employment with the Buyer
        Group, (ii) the period that installment severance payments
        are made to the employee or (iii) the period that ends on
        the date that the employee becomes eligible for coverage
        under another group medical plan; such continuation
        coverage shall be under the same terms and conditions of
        Buyer's Medical Plans applicable to such employee the day
        before his or her termination.  The costs that such
        employee will incur for coverage under the Buyer's Medical
        Plans during the period that such employee is entitled to
        coverage pursuant to the immediately preceding sentence
        shall not exceed the cost of coverage under Buyer's Medical
        Plans applicable to active employees who participate
        therein.  In addition, such period of coverage shall be
        considered to be part of the health care continuation
        period required to be provided to the employee under the
        applicable provisions of the Consolidated Omnibus Budget
        Reconciliation Act of 1985.  The Buyer's Severance
        Arrangement shall permit each eligible former Salaried
        Dearborn Business Employee who is employed in the United
        States to elect to receive severance payments in a lump sum
        or in installment payments in the same manner as provided
        by the Grace Severance Arrangement.

                  (b)  The provisions of Section 12.7(a) shall
        apply to each Salaried Dearborn Business Employee who is
        covered under the Buyer's Severance Arrangement and who: 
        (i) is subsequently involuntarily terminated from
        employment by the Buyer Group during the period that the
        Buyer's Severance Arrangement is required to remain in
        effect, due to plant consolidation, closing or relocation,
        or other circumstances that are not directly related to the
        employee's performance; (ii) voluntarily terminates his or
        her employment during the period that the Buyer's Severance
        Arrangement is required to remain in effect, as a result of
        the occurrence, without such employee's consent (which
        consent may not be subsequently revoked), of an
        unreasonable change in job duties, a change in work
        location that results in an unreasonable commuting distance
        from such employee's existing residence or a decrease in
        such employee's aggregate compensation such that the
        employee's resulting aggregate annual compensation will
        equal less than 85% of the aggregate compensation received
        by such employee for the 12-month period ending on the day
        before the Closing Date or (iii) on the Closing Date or on
        any date subsequent thereto, is absent from work due to
        disability or leave of absence (whether or not he or she is
        receiving worker's compensation payments), and who recovers
        from such disability (if applicable) and requests
        reinstatement to active employment status during the period
        that the Buyer's Severance Arrangement is required to
        remain in effect, but is denied reinstatement by any member
        of the Buyer Group.

                  (c)  Buyer shall cause the plan document and the
        summary plan description for the Buyer's Severance
        Arrangement to include a provision stating that the Buyer's
        Severance Arrangement may not be terminated or amended in a
        manner adverse to the covered employees prior to the date
        that is 18 months following the Buyer's Severance
        Arrangement's effective date.  Buyer shall cause the
        summary plan description for the Buyer's Severance
        Arrangement to be distributed to the Salaried Dearborn
        Business Employees within thirty days after the Closing
        Date.

                  (d)  After the Buyer's Severance Arrangement has
        been in effect for the required 18-month period, Buyer may
        terminate or revise the Buyer's Severance Arrangement, to
        the extent permitted by applicable law.  Salaried Dearborn
        Business Employees shall receive credit for prior service
        with the Grace Group for the purposes of applying any
        revised policy.

             12.8 Executive Compensation.  As of the Closing Date,
        the Continued Dearborn Business Employees who participated
        in the Grace Group's executive compensation plans or
        arrangements shall commence participation in executive
        compensation plans or arrangements maintained by the Buyer
        Group, which provide coverage and benefits to such persons
        which are, in the aggregate, not less favorable than those
        provided to such employees immediately prior to the Closing
        Date.

             12.9 Inactive Current Employees.  This Agreement shall
        not obligate the Buyer Group to employ any Dearborn
        Business Employee who is classified by the Grace Group as
        being on long-term disability leave as of the Closing Date. 
        Notwithstanding any other provision of this Agreement to
        the contrary, those Dearborn Business Employees who have
        been classified by the Grace Group as being on layoff,
        short-term disability or leave of absence (whether paid or
        unpaid or as a result of a workers  compensation claim) as
        of the Closing shall continue such status with the
        appropriate member of the Buyer Group after the Closing
        Date.

             12.10 Expatriate Employees.  The Dearborn Business
        Employees listed in the Schedule to this Section are
        referred to as the "Expatriate Employees."  Each Expatriate
        Employee has relocated from the country where he or she was
        a citizen or resident, and is a party to one of the
        agreements listed in the Schedule to this Section regarding
        relocation payments, home leave, repatriation rights and
        other matters (the "Expatriate Agreements").  Grace has
        delivered or made available to Buyer complete copies of the
        written Expatriate Agreements and a written summary of all
        other Expatriate Agreements, as currently in effect.  At
        the Closing Date, the Buyer Group shall assume (i) all
        obligations of the Grace Group under the Expatriate
        Agreements with respect to each Expatriate Employee who
        accepts employment with the Buyer Group, and (ii) all
        severance and repatriation obligations of the Grace Group
        under the Expatriate Agreements related to the termination
        of each Expatriate Employee who does not accept employment
        with the Buyer Group.

             12.11 Terms of Employment.  As to terms and conditions
        of employment of the Continued Dearborn Business Employees
        not described in this Article, and subject to the Employee
        Benefits Agreement, from and after the Closing, the
        Continued Dearborn Business Employees:  (i) shall be
        treated in a manner similar to the other similarly situated
        employees of the Buyer Group, (ii) shall be entitled to
        participate on the same basis as such other employees in
        all job training, career development and educational
        programs of the Buyer Group, and (iii) shall be entitled to
        fair and equitable consideration together with such other
        employees in connection with any management or executive
        job opportunities or any other promotional opportunities
        with the Buyer Group.

             12.12 Recognition of Seniority.  The Buyer Group shall
        recognize continuous service with the Grace Group
        (including predecessor employers to the extent such service
        is recognized by the Grace Group) for the purpose of
        determining seniority as used for the determination of
        service awards, severance benefits, vacations, sick leave
        and other terms and conditions of employment related to
        seniority. 

             12.13 Employee Information Sharing.  After the Closing
        Date, the Buying Companies shall, and shall cause the
        Transferred Companies (and, to the extent Buyer has the
        right to do so, the Transferred Joint Ventures) to, provide
        to the Grace Group, and the Selling Companies shall, and
        shall cause the other members of the Grace Group to,
        provide to the Buyer Group, on a continuing basis at no
        cost to the recipient, such information regarding persons
        who were employees of the Dearborn Business under the Grace
        Group's ownership, as may be reasonably requested.  This
        Section shall not compel any person to maintain records
        beyond the periods specified in Sections 15.2 and 15.3.

             12.14 Transfer of Employees of the Brazilian Business. 
        Any other provision of this Agreement to the contrary
        notwithstanding, at the Closing Date, all Current Employees
        who are employed in Brazil shall be transferred by Grace's
        Brazilian Subsidiary to Buyer's entity which will carry out
        the Dearborn Business in Brazil, by means of a change in
        current employment agreements and without termination
        thereof.

        prior to the Closing by written agreement of Grace and
        Buyer.

                  (b)  [Intentionally Omitted.]

        or before December 15, 1996, either Grace or Buyer may
        terminate this Agreement at any time thereafter by giving
        notice of such termination to the other in the manner
        provided in Section 18.1; provided, however, that (i) Grace
        may not terminate this Agreement pursuant to this Section
        13.1(c) if the Closing could take place in the event Grace
        made an election to close pursuant to Section 2.5 hereof
        and (ii) in the event of a change of control transaction
        affecting a party, such party shall not have the right to
        terminate this Agreement pursuant to this Section 13.1(c)
        if the failure to consummate the Closing by such date shall
        be due to the failure of the party seeking to terminate
        this Agreement to have fulfilled any of its obligations
        under this Agreement.

             13.2 Consequences of Termination.

                  (a)  In the event of a termination of this
        Agreement, in accordance with Section 13.1, this Agreement
        shall thereafter become void and have no effect; provided,
        however, that the termination of this Agreement shall not
        affect the rights of any Buying Company or Selling Company
        against the other for any breach of this Agreement.

                  (b)  The obligations of the parties under
        Sections 17.1 and 17.2 shall survive any termination of
        this Agreement.

        migrated to such adjacent property ("On-Site Property");

                            (B)  Toxic Tort Claims, Chromium Claims
        and Natural Resource Damage Claims relating to On-Site
        Properties, provided that indemnification for Natural
        Resource Damage Claims (including such Natural Resource

        thereof) are limited to claims arising under Environmental
        Laws that are in effect as of the Closing Date;

        Selling Companies, Transferred Companies or Transferred

        not be available for Hazardous Substances released or
        disposed of at such real property by a member of the Buyer
        Group, provided that this exception does not apply to such
        release or disposal by the Transferred Companies or
        Transferred Joint Ventures prior to the Closing Date; 

                            (B)  Toxic Tort Claims, Chromium Claims
        and Natural Resource Damage Claims relating to
        Formerly-Owned Properties;

        Hazardous Substances released at any location (other than
        locations covered by subsections (a)(i), (ii), and (iv)
        herein) ("Off-Site Properties") if such substances were
        generated, used, stored, treated, transported, disposed of,
        or released by or on behalf of the Dearborn Business or any
        predecessor thereto prior to the Closing Date, except that
        Grace shall not be obligated to provide indemnification
        pursuant to this subsection for the Cleanup of Hazardous
        Substances which were disposed of at such locations by any
        member of the Buyer Group, provided that this exception
        does not apply to such disposal by the Transferred

        Closing Date;

                            (B)  Toxic Tort Claims, Chromium Claims

        Business (including, without limitation, storage tanks
        owned or operated by the Dearborn Business or any
        predecessor thereto at such locations) or onto or under
        adjacent property to the extent such Hazardous Substances
        have migrated to such adjacent property ("Customer Sites"),

        Sites ("Customer Disposal Sites");

                            (B)  Toxic Tort Claims, Chromium Claims

        representations or warranties stated in Section 5.14.

                  (b)  Indemnification shall be available under
        this Section 14.2A only with respect to those claims as to
        which Claimant has provided a written notice to Grace
        ("Environmental Notice") during the periods specified in
        this subsection (b).  Such Environmental Notice must
        include, based on reasonably available information, the
        following:  (i) location; (ii) types of Hazardous
        Substances; (iii) the extent of any contamination, if
        known; (iv) the impacted media, if known; and (v) a copy of
        any notices filed with or received from any Governmental
        Authority or other person, or if no such notice has been
        filed or received, the basis upon which Claimant seeks
        indemnification.  Such Environmental Notice must be
        provided prior to the fifth anniversary of the Closing Date
        with respect to Cleanup, Toxic Tort Claims and Natural
        Resource Damage Claims relating to On-Site Properties,
        Customer Sites and Customer Disposal Sites, prior to the
        expiration of the 18-month period following the Closing
        Date with respect to claims covered by Section 14.2A(a)(v),
        or at any time for any other claim covered by this Section
        14.2A.  

                  (c)  Except as otherwise provided in Section
        14.2A(e), the Buyer Indemnified Group shall not be eligible
        for indemnification for claims covered by Section
        14.2A(a)(i), except for claims for which the Environmental
        Costs incurred by Claimant exceeds US $50,000 ("Covered
        On-Site Claims").  Grace shall not be obligated to
        reimburse the Buyer Indemnified Group unless and until the
        aggregate Environmental Costs of such Covered On-Site
        Claims exceeds US $6,000,000 (the "Environmental
        Deductible"), and then only with respect to the excess of
        such aggregate amount.  Once the Environmental Deductible
        has been exceeded, Grace shall reimburse the Buyer
        Indemnified Group for each Covered On-Site Claim, except
        for Chromium Claims, in accordance with the following and
        based on the year in which the Environmental Notice of such
        claim was filed:

                       (i)  Grace shall reimburse 80% of all
        Environmental Costs relating to claims made before the
        first anniversary of the Closing Date;

                       (ii) Grace shall reimburse 60% of all
        Environmental Costs relating to claims made on or after the
        first but before the second anniversary of the Closing
        Date;

                       (iii) Grace shall reimburse 60% of all
        Environmental Costs relating to claims made on or after the
        second anniversary but before the third anniversary of the
        Closing Date;

                       (iv) Grace shall reimburse 40% of all
        Environmental Costs relating to claims made on or after the
        third anniversary but before the fourth anniversary of the
        Closing Date;

                       (v)  Grace shall reimburse 20% of all
        Environmental Costs relating to claims made on or after the
        fourth anniversary but before the fifth anniversary of the
        Closing Date.

             For claims filed before the first anniversary of the
        Closing Date, this subsection shall apply to all Covered
        On-Site Claims even if it is unclear whether the release
        occurred prior to or subsequent to the Closing Date, except
        that Buyer shall be solely responsible for releases that
        are clearly identified as having occurred subsequent to the
        Closing Date.

             As to Chromium Claims that are also Covered On-Site
        Claims, once the Environmental Deductible has been
        exceeded, Grace shall reimburse the Buyer Indemnified Group
        for 90% of all Environmental Costs related to such claims,
        without respect to when the Environmental Notice for such
        claim was submitted.

             The Buyer Indemnified Group shall be responsible for
        their allocation of Environmental Costs as set forth above
        regarding each claim.

                  (d)  (i)  Indemnification by Grace for any breach
        of Section 5.14 shall be as follows:

                            (A)  any Environmental Costs related to
        Cleanup at or related to On-Site Property shall be
        allocated in accordance with Section 14.2A(c) above;

                            (B)  limited to fines, penalties, legal
        expenses and any other costs of defending any litigation or
        administrative proceeding for such breaches related to
        noncompliance with Environmental Law, except for matters
        otherwise covered by subsection (d)(i)(A) above;

                            (C)  any Environmental Costs related to
        Section 14.2A(a)(iv) shall be allocated in accordance with
        Section 14.2A(f).

                       (ii) With regard to subsection (d)(i)(B) and
        all other claims related to any other breach of Section
        5.14 not referred to in subsection(d)(i)(A) or (C) above,
        the Buyer Indemnified Group shall not be eligible for
        indemnification with respect to the breach of any
        representation of Section 5.14(b)(i), (ii), or (iii) unless
        and until the aggregate amount of all such Buyer
        Indemnified Group's indemnified costs exceeds US
        $1,000,000, and then only with respect to the excess of
        such aggregate amount; except that such limits shall not
        apply to breaches of environmental representations that
        relate to matters covered by Section 14.2A(a)(ii) and
        (iii).

                  (e)  Notwithstanding the limitations set forth in
        subsection 14.2A(c) above, to the extent that any On-Site
        Property becomes listed on the NPL solely as a result of
        the release of Hazardous Substances prior to the Closing
        Date, Grace shall have responsibility for 100% of all
        Environmental Costs related to the Cleanup on that property
        commencing on the day the site s nomination to the NPL is
        made final by publication in the Federal Register.  Until
        such time, the allocation set forth in Section 14.2A(c)
        above shall be used.  Grace, at its option, may assume
        control of any project for which it has 100% responsibility
        under this subsection.

                  (f)  The Buyer Indemnified Group shall not be
        eligible for indemnification under Section 14.2A(a)(iv),
        unless and until the aggregate of all Environmental Costs
        for which indemnification is sought exceeds US $10,000,000,
        and then only with respect to 90% of the excess of such
        aggregate.
         
                  (g)  Grace's aggregate indemnity with respect to
        (i) Cleanup, Toxic Tort Claims and Natural Resource Damage
        Claims relating to On-Site Properties and Customer Sites;
        (ii) Undisclosed Product Liabilities; and (iii) Undisclosed
        Employee Liabilities, shall be limited to 10% of the Total
        Purchase Price.  This limitation does not apply to Chromium
        Claims arising at or from any location or any claims
        arising under Section 14.2A with respect to Formerly-Owned
        Properties or Off-Site Properties.

                  (h)  The dollar thresholds set forth in this
        Section 14.2A have been negotiated for the special purpose
        of the provisions to which they relate, and are not to be
        taken as evidence of the level of "materiality" for
        purposes of any statutory or common law which may be
        applicable to the transactions contemplated by this
        Agreement under which a level of materiality might be an
        issue.

             14.3 Buyers' Indemnification.  

                  (a)  Subject to the terms and limitations of this
        Article, the Buying Companies shall, jointly and severally,
        indemnify and hold harmless the Selling Companies, their
        Subsidiaries, directors, officers and employees (the "Grace
        Indemnified Group"), as the case may be, from and against
        all Damages incurred by any member of the Grace Indemnified
        Group arising out of, incurred in connection with or
        relating to (i) the breach by or non-performance of any
        Buying Company, or subsequent to the Closing any
        Transferred Company or Transferred Joint Venture, of any of
        its covenants or agreements under this Agreement or any of
        the other Transaction Documents, (ii) any breach of or
        inaccuracy in any representation or warranty of Buyer set
        forth in Article 6, (iii) the failure of any Transferred
        Company or Transferred Joint Venture subsequent to the
        Closing to perform or fulfill its obligations under any
        contract, agreement or obligation for which any member of
        the Grace Group is or may be liable, as a guarantor or
        otherwise, (iv) any of the Total Dearborn Liabilities,
        including, without limitation, any liability or obligation
        relating to the Dearborn Business or the Total Dearborn
        Assets based upon or arising under any Environmental Law,
        except as may be otherwise provided in this Article 14, (v)
        the Buyer Group's hiring practices and decisions with
        respect to the Dearborn Business (including, but not
        limited to, any claims by any Current Employee alleging he
        or she was not hired or was terminated, on or after the
        Closing Date in violation of U.S. or non-U.S. non-
        discrimination laws), (vi) any claim concerning any aspect
        of the employment or termination of employment, at or after
        the Closing, of any Continued Dearborn Business Employee,
        (vii) (Intentionally Omitted), (viii) any claim made by any
        Dearborn Business Employee or any Transitional Services
        Employee for any severance pay or other severance benefit,
        including, but not limited to, any individual who becomes
        entitled to such pay or benefits under the Grace Severance
        Arrangement before, on or after the Closing Date and any
        individual who under applicable law or otherwise is
        entitled to severance upon dismissal by the Selling
        Companies after refusing an offer to become an employee of
        the Buyer Group, (ix) any change in the collective
        organization or joint committees applicable to any
        Continued Dearborn Business Employee that occurs at or
        after the Closing, or applicable to any Transitional
        Services Employee who commences employment with any member
        of the Buyer Group that occurs on or after the date that
        such employee commences such employment; (x) any claim made
        by any Dearborn Business Employee based on any agreement
        between the employee and any member of the Grace Group that
        was in the ordinary course of business or (xi) any claim
        under the U.S. Worker Adjustment and Retraining
        Notification Act, 29 U.S.C.SECTIONSECTION 2101 et seq., or any
        comparable U.S., state or non-U.S. law arising out of any
        actions taken by the Buyer Group at or after the Closing or
        as a result of the transactions contemplated by this
        Agreement.

                  (b)  The representations and warranties of Buyer
        set forth in Article 6 shall survive the Closing.

             14.4 Limitations.

                  (a)  The Buying Companies and the other members
        of the Buyer Group may not assert any claim for
        indemnification under this Article (a "Buyers  Claim") with
        respect to the breach of or inaccuracy in any
        representation or warranty in Section 5.5 through Section
        5.13 and Section 5.15 through the end of Article 5 unless
        and until the aggregate amount of all such Buyers' Claims
        give rise to Damages that exceed US $10,000,000 and then
        only with respect to the excess of such aggregate Buyers'
        Claims over US $10,000,000; provided, however, that this
        Section 14.4 shall not apply to (i) any indemnification by
        Grace for any Damages asserted against, imposed upon or
        incurred by the breach or inaccuracy in any representations
        and warranties contained in Section 5.17 (Brokers).

                  (b)  The dollar thresholds set forth in this
        Section have been negotiated for the special purpose of the
        provision to which they relate, and are not to be taken as
        evidence of the level of "materiality" for purposes of any
        statutory or common law which may be applicable to the
        transactions contemplated by this Agreement under which a
        level of materiality might be an issue.

                  (c)  Any payment by Buyer (or a Member of the
        Buyer Group) or Grace (or a Member of the Grace Group)
        under this Article 14 will be treated as an adjustment to
        the Total Purchase Price; provided, however, that to the
        extent it cannot be so characterized for tax purposes or if
        such indemnification occurs after the expiration of the
        statute of limitations for the 1996 taxable year, the
        recipient of any such payment shall be entitled to an
        additional payment to cover Taxes on the payment less any
        allowable Tax deductions attributable to payment of the
        indemnified claim.

             14.5 Defense of Third Party Claims.

                  (a)  The Buying Companies shall, and shall cause
        the other members of the Buyer Group to, notify Grace in
        writing promptly after a Third Party Claim is asserted
        against or sought to be collected from any member of the
        Buyer Group for which the Grace Group may be liable under
        this Agreement, or which is to be taken into account for
        purposes of the dollar thresholds in Sections 14.2A or
        14.4.  The Selling Companies shall, and shall cause the
        other members of the Grace Group to, notify Buyer in
        writing promptly after a Third Party Claim is asserted
        against or sought to be collected from any member of the
        Grace Group for which the Buyer Group may be liable under
        this Agreement.  It shall be a necessary condition of any
        claim by any entity for indemnification under this
        Agreement with respect to any Third Party Claim, or for
        such Third Party Claim to be taken into account for
        purposes of the dollar thresholds under Sections 14.2A or
        14.4, that the entity seeking indemnification or to have
        such claim taken into account (the "Claimant") notify Grace
        on behalf of the Grace Group, if the Claimant is a member
        of the Buyer Group, or Buyer on behalf of the Buyer Group,
        if the Claimant is a member of the Grace Group, prior to
        the time when the notice recipient's ability to contest the
        Third Party Claim would be materially impaired by lack of
        notice.  If a Buyer Group Claimant fails to give such
        notice of a Third Party Claim and such Claimant's failure
        to provide such notice has materially prejudiced the
        indemnifying party's ability to defend the Third Party
        Claim, then all members of the Buyer Group shall be deemed
        to have waived all rights to indemnification with respect
        to such Third Party Claim.  If a Grace Group Claimant fails
        to give such notice of a Third Party Claim and such
        Claimant's failure to provide such notice has materially
        prejudiced the indemnifying party's ability to defend the
        Third Party Claim, then all members of the Grace Group
        shall be deemed to have waived all rights to
        indemnification with respect to such Third Party Claim.  

                  (b)  Except as otherwise provided in Section
        14.5(d), Grace, or any other member of the Grace Group, may
        undertake the defense of a Third Party Claim that the Buyer
        Group has notified Grace of, by notice to Buyer not later
        than 60 calendar days after receipt by Grace of the Buyer
        Group's notice of the claim.  Failure on the part of the
        Grace Group to so notify Buyer that it will undertake such
        defense shall be deemed to be a waiver of the Grace Group's
        right to undertake such defense.  If the Grace Group
        undertakes the defense of any Third Party Claim, it shall
        control the investigation and defense thereof, except that
        the Grace Group shall not require any member of the Buyer
        Group, without its prior written consent, to take or
        refrain from taking any action in connection with such
        Third Party Claim, or make any public statement, that it
        reasonably considers to be against its interest, nor shall
        the Grace Group, without the prior written consent of
        Buyer, consent to any settlement that (i) requires any
        member of the Buyer Group to make any payment that is not
        fully indemnified under this Agreement or taken into
        account under Sections 14.2A or 14.4; and (ii) does not
        include as an unconditional term thereof the giving by the
        claimant or the plaintiff to the relevant member of the
        Buyer Indemnified Group against whom such Third Party Claim
        is asserted, a release from all liability in respect of
        such Third Party Claim or (iii) provides for any
        nonmonetary damages which would materially adversely affect
        the Dearborn Business; and subject to the Grace Group's
        control rights, the Buyer Group may participate in such
        investigation and defense, at its own expense, except as
        otherwise provided in Section 14.5(d) herein.  If the Grace
        Group does not undertake the defense of a tendered Third
        Party Claim, then except as otherwise provided in Section
        14.5(d), the Buyer Group shall control such investigation
        and defense, except that the Buyer Group shall not require
        a member of the Grace Group, without its prior written
        consent, to take or refrain from taking any action in
        connection with such Third Party Claim, or make any public
        statement, that such entity reasonably considers to be
        against its interest, nor shall the Buyer Group, without
        the prior written consent of Grace, consent to any
        settlement; and subject to the Buyer Group's control
        rights, the Grace Group may participate in such
        investigation and defense, at its own expense.

                  (c)  Except as otherwise provided in Section
        14.5(d), Buyer, or any other member of the Buyer Group, may
        undertake the defense of a Third Party Claim that the Grace
        Group has notified Buyer of, by notice to Grace not later
        than 60 calendar days after receipt by Buyer of the Grace
        Group's notice of the claim.  Failure on the part of the
        Buyer Group to so notify Grace that it will undertake such
        defense shall be deemed to be a waiver of the Buyer Group's
        right to undertake such defense.  If the Buyer Group
        undertakes the defense of any Third Party Claim, it shall
        control such investigation and defense, except that the
        Buyer Group shall not require any member of the Grace
        Group, without its prior written consent, to take or
        refrain from taking any action in connection with such
        Third Party Claim, or make any public statement, that it
        reasonably considers to be against its interest, nor shall
        the Buyer Group, without the prior written consent of
        Grace, (i) consent to any settlement that requires any
        member of the Grace Group to make any payment that is not
        fully indemnified under this Agreement; (ii) does not
        include as an unconditional term thereof the giving by the
        claimant or the plaintiff to the relevant member of the
        Grace Indemnified Group against whom such Third Party Claim
        is asserted, a release from all liability in respect of
        such Third Party Claim or (iii) provides for any
        nonmonetary damages which materially adversely affect the
        business conducted by the Grace Group other than the
        Dearborn Business and subject to the Buyer Group's control
        rights, the Grace Group may participate in such
        investigation and defense, at its own expense, except as
        otherwise provided in Section 14.5(d).  If the Buyer Group
        does not undertake the defense of a tendered Third Party
        Claim, then except as otherwise provided in Section
        14.5(d), the Grace Group shall control such investigation
        and defense, except that the Grace Group shall not require
        a member of the Buyer Group, without its prior written
        consent, to take or refrain from taking any action in
        connection with such Third Party Claim, or make any public
        statement, that such entity reasonably considers to be
        against its interest, nor shall the Grace Group, without
        the prior written consent of Buyer, consent to any
        settlement; and subject to the Grace Group's control
        rights, the Buyer Group may participate in such
        investigation and defense, at its own expense.

                  (d)  If a conflict of interest exists or is
        reasonably likely to exist between the Grace Group and the
        Buyer Group with respect to a Third Party Claim that would
        make it inappropriate in the judgment of the Claimant in
        its reasonable discretion for the same counsel to represent
        both the Claimant and the indemnifying party, then neither
        group shall be entitled to assume the defense thereof.  In
        such event the Buyer Group and the Grace Group shall each
        be entitled to conduct its own investigation and defense,
        but the parties shall cooperate to conduct such
        investigation and defense as efficiently as possible.  If a
        member of the Grace Group is required to indemnify the
        Buyer Group with respect to such Third Party Claim, it
        shall pay the reasonable attorneys' fees and expenses of
        one individual or firm representing the Buyer Group with
        respect thereto.  If a member of the Buyer Group is
        required to indemnify the Grace Group with respect to such
        Third Party Claim, it shall pay the reasonable attorneys'
        fees and expenses of the individual or firm representing
        the Grace Group with respect thereto.

                  (e)  The Buying Companies shall, and shall cause
        the other members of the Buyer Group to, and the Selling
        Companies shall, and shall cause the other members of the
        Grace Group to, make available to each other, their counsel
        and other representatives, all information and documents
        reasonably available to them that relate to any Third Party
        Claim, and otherwise cooperate as may reasonably be
        required in connection with the investigation and defense
        thereof.

             14.6 No Consequential or Lost Profit Damages for
        Breaches of Representations for Direct Claims.  No party to
        this Agreement, nor any other member of the Grace Group or
        the Buyer Group, shall seek or be entitled to incidental,
        indirect or consequential damages or damages for lost
        profits in any claim for indemnification in a Direct Claim
        based upon a breach of or inaccuracy in the representations
        and warranties contained in Article 6 or Article 5,
        respectively.  Nothing set forth herein will otherwise
        limit either party to this Agreement or any other member of
        the Grace Group or the Buyer Group from seeking or being
        entitled to incidental, indirect or consequential damages
        or damages for lost profits (i) in connection with any
        other breach of this Agreement or (ii) if such damages are
        payable to a third party in connection with a Third Party
        Claim.

             14.7 No Duplication.  In the event that any
        circumstance which results in an adjustment to the Total
        Purchase Price, or would result in such an adjustment but
        for the limitations of Section 4.A (c)(iii)(A) or (B),
        would also constitute a breach of any representation or
        warranty by Grace under Article 5, the Selling Companies
        shall have no obligation to indemnify the Buying Companies
        with respect to such breach except pursuant to such
        adjustment.

             14.8 Vacation Pay.  Grace will indemnify Buyer in
        accordance with the terms set forth on the Schedule to this
        Section 14.8.

                      COOPERATION IN VARIOUS MATTERS

             15.1 Mutual Cooperation.  After the Closing, each
        party to this Agreement shall, and shall cause its
        subsidiaries to, cooperate with each other party and its
        subsidiaries as reasonably requested by such other party in
        connection with the prosecution or defense of any claims or
        other matters relating to the Dearborn Business.  Such
        cooperation shall include furnishing testimony and other
        evidence, permitting access to employees and providing
        information regarding the whereabouts of former employees. 
        The requesting party shall reimburse the other party for
        any out-of-pocket expenses incurred by it in connection
        with such request and owed to third parties.

             15.2 Preservation of Buying Companies' Files and
        Records.  Except for books and records relating to Taxes
        which shall be addressed in the Tax Procedures Agreement,
        following the Closing, the Buying Companies shall, and
        shall cause the other members of the Buyer Group to,
        preserve all files and records in their possession relating
        to the Dearborn Business prior to the Closing, allow the
        Grace Group access to such files and records and the right
        to make copies and extracts therefrom at any time during
        normal business hours, and not dispose of any of such files
        or records that are less than ten years old, except that at
        any time after the third anniversary of the Closing, any
        member of the Buyer Group may give Grace written notice of
        its intention to dispose of any files or records that are
        more than five years old, specifying the items to be
        disposed of in reasonable detail.  Any member of the Grace
        Group may, within a period of sixty days after Grace's
        receipt of any such notice, notify Buyer of the Grace
        Group's desire to retain one or more of the items to be
        disposed of.  Buyer shall, upon receipt of such a notice
        from a member of the Grace Group, deliver to such member of
        the Grace Group, at Grace's expense, the items that the
        Grace Group has elected to retain.

             15.3 Preservation of Selling Companies' Files and
        Records.  Except for books and records relating to Taxes
        which shall be addressed in the Tax Procedures Agreement,

        shall cause the other members of the Grace Group to,
        preserve all files and records in their possession relating
        to the Dearborn Business prior to the Closing, allow the
        Buyer Group access to such files and records and the right
        to make copies and extracts therefrom at any time during
        normal business hours, and not dispose of any of such files
        or records that are less than ten years old, except that at
        any time after the third anniversary of the Closing, any
        member of the Grace Group may give Buyer written notice of
        its intention to dispose of any files or records that are
        more than five years old, specifying the items to be
        disposed of in reasonable detail.  Any member of the Buyer
        Group may, within a period of sixty days after Buyer's
        receipt of any such notice, notify Grace of the Buyer
        Group's desire to retain one or more of the items to be
        disposed of.  Grace shall, upon receipt of such a notice
        from a member of the Buyer Group, deliver to such member of
        the Buyer Group, at Buyer's expense, the items that the
        Buyer Group has elected to retain.

             15.4 Publicity.  Except as otherwise may be required
        by law, neither party shall make an initial public
        statement (including, without limitation, any press
        release) with respect to this Agreement and the other
        Transaction Documents, and the transactions contemplated
        hereby and thereby, without the prior written consent of
        the other party, which consent shall not be unreasonably
        withheld or delayed.  After the initial public statement,
        either party shall have the right to make public statements
        regarding this transaction without the consent of such
        other party.

                                ARTICLE 16
                           POST-CLOSING MATTERS

             16.1 Reports.  Other than information relating to
        Taxes which shall be addressed in the Tax Procedures
        Agreement, the Buying Companies shall, and shall cause the
        Transferred Companies (and to the extent the Buying
        Companies have the right to do so, the Transferred Joint
        Ventures) and their respective employees to, prepare on a
        timely basis, in accordance with the instructions of the
        Grace Group, such financial and other reports and
        statements relating to the Dearborn Business, the
        Transferred Companies or the Transferred Joint Ventures for
        periods prior to the Closing as may be reasonably requested
        by Grace.

             16.2 Renewal of Guaranteed Items.  Without the prior
        written consent of the Treasurer or any Assistant Treasurer
        of Grace, the Buying Companies shall not, and shall not
        permit the Transferred Companies (or, to the extent the
        Buying Companies have the right to do so, the Transferred
        Joint Ventures) or any other member of the Buyer Group to,
        renew or extend the term of, increase its obligations
        under, or transfer to a third party, any lease, loan,
        contract or other obligation for which Grace or any other
        member of the Grace Group is or may be liable, as
        guarantor, original tenant, primary obligor, or otherwise,
        unless all obligations of the Grace Group with respect
        thereto are thereupon terminated by documentation
        satisfactory in form and substance to Grace.

             16.3 Payment and Discharge of Certain Intercompany
        Liabilities.

                  (a)  Surviving Intercompany Accounts that are not
        between units of the Dearborn Business shall be paid in
        cash, regardless of whether prior to the Closing such items
        would have been settled by cash payment or by other means,
        at the earlier of (i) 30 calendar days after receipt of an
        invoice therefor or (ii) the time payment is made pursuant
        to Section 4.7, other than the account receivable from the
        Dearborn Japan J.V. by Grace Japan KK which shall remain in
        effect pursuant to its terms.  Except for Surviving
        Intercompany Accounts and as otherwise specifically
        provided in the Ancillary Agreements, any amounts owed by
        any member of the Grace Group to any Transferred Company or
        Transferred Joint Venture, or by any Transferred Company or

        Group shall be deemed paid and discharged, effective upon
        the occurrence of the Closing.

                  (b)  All checks written by Dearborn U.S. in the
        ordinary course of business prior to the Closing will be
        honored by Grace and all obligations of Dearborn U.S. to

        discharged, effective as of the Closing.  All funds in the
        depository accounts of Dearborn U.S. on the Closing Date
        shall be the property of Grace, except for a disbursement
        account and an imprest payroll account, each of which shall
        have a balance of US $1,000.00 at the Closing and
        signatories designated by Buyer U.S.

                  (c)  At Grace s request at any time and from time
        to time after the Closing, Buyer shall cause Dearborn U.S.
        to promptly reimburse Grace for any amounts paid directly
        by the Grace Group after the Closing to third parties on
        account of expenses incurred prior to the Closing that
        relate directly and exclusively to the Dearborn Business.

        Closing, (a) Grace Dearborn, N.V., Dearborn Canada,
        Dearborn France, Dearborn Netherlands and Dearborn Sweden
        shall each change its corporate name to a name that does
        not include the name "Grace" and initiate any necessary
        legal filings with the appropriate Governmental Authority
        to effectuate a name change and (b) the Transferred
        Companies, Transferred Joint Ventures and Buying Companies
        shall have no right to use the "Grace" name, except that
        for a period ending on the later to occur of (i) six months
        after the Closing or (ii) November 30, 1996, the
        Transferred Companies, Transferred Joint Ventures and
        Buying Companies shall have the right to use any
        catalogues, sales and promotional materials and printed
        forms that use such name and are included in the Total
        Dearborn Assets or the assets of any Transferred Company or
        Transferred Joint Venture as of the Closing, or that have
        been ordered prior to the Closing for use in the Dearborn
        Business, but only to the extent that it is not practicable
        to remove or cover up the "Grace" name; provided, however,
        Buyer shall move as expeditiously as possible to cancel
        registrations with the appropriate Governmental Authorities
        to effectuate such name change.  The Buying Companies shall
        use reasonable efforts to minimize such usage and to
        discontinue it as soon as practicable after the Closing.

             16.5 Intercompany Agreements.  Except for the
        Intellectual Property License and Assignment Agreement
        between Grace and Dearborn U.S. dated as of November 30,

        Grace Group that have been assigned to Dearborn U.S.
        thereunder, the other agreements entered into between
        members of the Grace Group and Dearborn U.S. in connection
        with the transfer to Dearborn U.S. of the Dearborn Business
        in the United States and the Ancillary Agreements, (a) all
        contracts, licenses, agreements, commitments or other
        arrangements between Grace or any other member of the Grace
        Group and any Transferred Company, Transferred Joint
        Venture or the Dearborn Business unit of any Selling
        Company, whether written or oral, and whether express or
        implied, pursuant to which Grace (or any other member of
        the Grace Group) provides management, administrative,
        legal, financial, accounting, data processing, insurance,
        technical support, or other services to the Dearborn
        Business or such Transferred Company or Transferred Joint
        Venture, or the use of any assets of any member of the
        Grace Group, or pursuant to which rights, privileges or
        benefits are accorded to the Dearborn Business or any
        Transferred Company or Transferred Joint Venture as a unit
        of the Grace Group, shall terminate as of the Closing, and
        (b) after the Closing, the Buying Companies, the
        Transferred Companies and the Transferred Joint Ventures
        shall have no rights under any similar contract, license,
        agreement, commitment or arrangement with Grace (or any
        other member of the Grace Group).

             16.6 Parent Guaranty.  As soon as possible after the
        NMC Divestment (as defined herein), Grace shall obtain and
        deliver a guaranty from WRG-DE (as defined herein) of the
        full payment and performance of the obligations of Grace
        under this Agreement and the Transaction Documents, which
        guaranty shall be in form and substance reasonably
        satisfactory to Buyer.  Upon receipt of such guaranty, the
        guaranty of WRG contained in this Agreement shall be of no
        further force and effect.  For purposes of this Agreement,
        (i) "NMC Divestment" shall mean a transaction of which the
        primary purpose is Grace's divestment of its Subsidiary,
        National Medical Care, Inc., or to cause Grace and National
        Medical Care, Inc. to no longer be under common control;
        and (ii) "WRG-DE" shall mean Grace Holdings, Inc., a
        Delaware corporation, or any other public company owning

             19.1 Entire Agreement.  This Agreement, including the
        Schedules hereto, and the other Transaction Documents set
        forth the entire agreement and understanding of the parties
        and related persons with respect to the subject matter
        hereof and supersede all prior agreements, arrangements and
        understandings relating thereto, except for the
        Confidentiality Agreement.

             19.2 Governing Law.  This Agreement shall be governed
        by and construed in accordance with the laws of New York,
        excluding (a) any conflict-of-laws provisions thereof that
        would otherwise require the application of the law of any
        other jurisdiction, and (b) if applicable, the United
        Nations Convention on Contracts for the International Sale
        of Goods.

             19.3 Submission to Jurisdiction.  Each Buying Company
        and Selling Company hereby irrevocably submits in any suit,
        action or proceeding arising out of or relating to this
        Agreement or any of the other Transaction Documents to
        which it is or will be a party, or any of its obligations
        hereunder or thereunder, to the jurisdiction of the United
        States District Court for the Southern District of New York
        and the jurisdiction of any court of general jurisdiction
        of the State of New York located in New York County, and
        waives any and all objections to such jurisdiction that it
        may have under the laws of the State of New York or any
        other jurisdiction, except to the extent that this
        Agreement or any other Transaction Document specifically
        provides that a particular dispute is to be referred to a
        court in another jurisdiction or to resolution by
        arbitration or experts.

             19.4 Governing Language.  This Agreement in the
        English language shall be the definitive and controlling
        text, notwithstanding any translation into another
        language.

             19.5 Successors; No Third-Party Beneficiaries.  This
        Agreement shall not be assignable by either party hereto
        except with the prior written consent of the other;
        provided, however, that the Buying Companies may transfer
        or assign, in whole or from time to time in part, to one or
        more of their Subsidiaries, the right to purchase all or a
        portion of the Total Dearborn Assets, Transferred Shares,
        Transferred Interests and the Transferred Investment, but
        no such transfer or assignment shall relieve Buyer of its
        obligations hereunder.  This Agreement shall be binding
        upon and inure to the benefit of the parties hereto and
        their respective successors and permitted assigns.  Nothing
        in this Agreement, expressed or implied, is intended to
        confer upon any Person (including any employee or former
        employee) other than the Buying Companies, the Selling
        Companies or their successors and permitted assigns, any
        rights or remedies under or by reason of this Agreement. 
        Further, no provision of this Agreement shall create any
        such rights in any such Persons in respect to any benefits
        that may be provided, directly or indirectly, under any
        employee compensation and benefit plans, programs, policies
        and arrangements (to include fringe benefits) or any plan
        or arrangement which may be established by Buyer or any of
        its affiliates.

             19.6 Amendments and Waivers.  This Agreement may be
        amended, superseded or terminated, and any of the terms
        hereof may be waived, only by a written instrument
        specifically referring to this Agreement and specifically
        stating that it amends, supersedes or terminates this
        Agreement or waives any of its terms, executed by all
        parties, or in the case of a waiver, by the party waiving
        compliance.  Failure of any party to insist upon strict
        compliance with any of the terms of this Agreement in one
        or more instances shall not be deemed to be a waiver of its
        rights to insist upon such compliance in the future, or
        upon compliance with other terms hereof.

             19.7 Counterparts.  This Agreement may be executed in
        two or more counterparts, each of which shall be an
        original, but all of which shall constitute but one
        agreement.

             19.8 Captions.  The captions used in this Agreement
        are for convenience of reference only and shall not be
        considered in the interpretation of the provisions hereof.


          IN WITNESS WHEREOF, the parties have executed this
     instrument on the date first above written.
