               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


To the Board of Directors of
W.R. Grace & Co. - Conn.

In our opinion, the accompanying combined balance sheet and the related combined
statements of operations and of cash flows present fairly, in all material
respects, the financial position of the Grace Dearborn Business ("the Dearborn
Business") of W.R. Grace & Co. - Conn. ("Grace") at December 31, 1995 and 1994,
and the results of its operations and its cash flows for each of the three years
in the period ended December 31, 1995, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
management of Grace and the Dearborn Business; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

The Business was a separate product line of Grace and, as disclosed in Note 10
to the accompanying financial statements, has engaged in various transactions
and relationships with other Grace entities. Because of these relationships, it
is possible that the terms of these transactions are not the same as those that
would result from transactions among wholly unrelated parties.

1.     Summary of Significant Accounting Policies

       The Business
       On June 28, 1996, Betz Laboratories, Inc. ("Betz") purchased the Grace
       Dearborn Business (the "Dearborn Business") of W.R. Grace & Co. - Conn.
       and subsidiaries ("Grace") by acquiring certain assets and assuming
       certain liabilities of the Dearborn Business worldwide from Grace as
       provided in the Grace Dearborn Worldwide Purchase and Sale Agreement
       dated March 11, 1996, as amended on June 28, 1996 ("the Agreement").

       The Dearborn Business provides water management products and related
       customer support to a worldwide range of industries to prevent scaling,
       corrosion, fouling, and microbiological problems in utility and process
       systems, and to facilitate liquid/solid separation.

       Basis of Presentation
       Under the terms of the Agreement, Betz acquired from Grace (1) its
       partnership interests in Dearborn USA, Limited Partnership*, (2) the
       stock of Grace Dearborn N.V., Alexim N.V. and Finac N.V., all Belgian
       corporations; the stock of Grace Dearborn, Inc.*, a Canadian corporation;
       the stock of Grace Service Chemicals S.A., a French corporation; the
       stock of Grace Dearborn B.V., a Netherlands corporation; the stock of
       Grace Dearborn AB* and Dearborn Holdings AB, both Swedish corporations,
       and (3) the other worldwide operating assets and liabilities of the
       Dearborn Business.

       The Dearborn Business maintains over 120 sales offices worldwide, with
       many of the 70 offices located outside of North America being shared with
       other Grace operations. In addition, the Dearborn Business operates six
       administrative centers (two in North America and four in Europe) and
       shares administrative offices in the European, Asia Pacific and Latin
       American regions with other Grace operations. The Dearborn Business also
       has six research and development laboratories (four located at
       manufacturing facilities and one each in Belgium and Brazil) and 19
       worldwide customer service laboratories.

       The Dearborn Business' assets and liabilities are located in the
following regions/countries:

       *    Includes manufacturing operations.

       **   Excludes manufacturing operations of the Dearborn Business
            retained by Grace, for which Grace will manufacture Dearborn
            Business products for Betz under tolling arrangements.


       These financial statements present the historical financial position,
       results of operations, and cash flows of the Dearborn Business previously
       included in the Grace consolidated financial statements. The Securities
       and Exchange Commission, in Staff Accounting Bulletin Number 55, requires
       that historical financial statements of a subsidiary, division, or lesser
       business component of another entity include certain expenses incurred by
       the parent on its behalf. Accordingly, included in the accompanying
       financial statements are costs allocated to the Dearborn Business by
       Grace (see Note 10).

       All transactions between the Dearborn Business' locations included in the
       financial statements are herein referred to as "intracompany"
       transactions whereas transactions with Grace are referred to herein as
       "intercompany" or "related party" transactions.


       Basis of Combination
       The combined financial statements have been prepared by combining the
       assets and liabilities of the Dearborn Business. All intracompany
       balances, intracompany sales and intracompany profit have been eliminated
       in preparing the financial statements. Account balances of the Dearborn
       Business with Grace have been reported as part of parent company
       investment, except for those related to the sale of product and
       reimbursement of selling and personnel costs which have been included in
       accounts receivable.


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

       Financial Instruments
       At December 31, 1995 and 1994, the carrying value of the Dearborn
       Business' financial instruments such as cash, trade accounts receivable
       and accounts payable approximate fair value, based on the short-term
       maturities of these instruments.

       Revenue Recognition
       Revenue recognition generally takes place when goods are shipped and/or
       when related support is provided to customers.

       Concentration of Credit Risk
       Financial instruments which potentially expose the Dearborn Business to
       concentrations of credit risk consist primarily of trade accounts
       receivable. To minimize this risk, ongoing credit evaluations of
       customers' financial condition are performed, although collateral is not
       required. In addition, the Business maintains allowances for potential
       credit losses and such losses, in the aggregate, have not exceeded
       management expectations. None of the Dearborn Business' customer
       receivables are individually significant.

       Inventories
       Finished goods and work-in-process inventories are valued at the lower of
       cost or market. Cost flow is based on the last-in, first-out (LIFO)
       method in the U.S., and first-in, first-out (FIFO) method in other
       regions. Raw materials are valued at the lower of FIFO cost or realizable
       value.

       Properties and Equipment
       Properties and equipment are stated at cost. Major renewals and
       improvements which extend the lives of the respective assets are
       capitalized. Maintenance, repairs and renewals which do not extend the
       lives of the respective assets are charged to income as incurred. Fully
       depreciated assets are retained in properties and equipment and related
       accumulated depreciation accounts until they are removed from service.

       For financial reporting purposes, depreciation is computed using the
       straight-line method over the estimated useful lives of the assets
       specified below:

                                                                       Useful
                                                                       lives
          Category                                                     (years)

       The financial statements include $12,796, $9,924 and $9,405 of
       depreciation expense in 1995, 1994 and 1993, respectively.

       The cost of reusable bulk containers, which are used to ship product to
       customers and then returned when empty, is amortized on a straight-line
       basis over a 3 to 15 year period depending on the type of container and
       end user. The cost of leased custom-designed feed and monitoring
       equipment is amortized on a straight-line basis over the lease period.
       The cost of feed and related equipment loaned to customers, where
       ownership is retained by the Dearborn Business, is usually built into the
       selling price of the product and is amortized on a straight-line basis
       usually over a 3 year period.


       Goodwill and Other Intangibles
       Goodwill is amortized using the straight-line method over a 40 year
       period. Other intangibles are amortized on a straight-line basis in
       accordance with the nature of the asset (approximately 3-15 years).


       Impairment
       The Dearborn Business has adopted Statement of Financial Accounting
       Standards No. 121 (FAS 121), "Accounting for the Impairment of Long-Lived
       Assets and for Long-Lived Assets to Be Disposed Of." In accordance with
       this Statement, the Dearborn Business reviews long-lived assets and
       related goodwill for impairment whenever events or changes in
       circumstances indicate that the carrying amount of such assets may not be
       fully recoverable.


       Income Taxes
       Historically, except in Canada, Belgium, France and the Netherlands, the
       results of the Dearborn Business' operations have been included in the
       income tax returns of Grace. As such, Grace paid income taxes
       attributable to the Dearborn Business; this has been reflected in parent
       company investment. The income tax expense and other tax related
       information in these financial statements have been determined as if the
       operations of the Dearborn Business were not eligible to be included in
       the tax returns of Grace but rather were stand-alone taxpayers.

       The provisions of Statement of Financial Accounting Standards No. 109
       (FAS 109) "Accounting for Income Taxes" have been retroactively applied
       to these financial statements. FAS 109 is an asset and liability approach
       that requires the recognition of deferred tax assets and liabilities for
       the expected future consequences of events that have been recognized in
       the financial statements or tax returns. In estimating future tax
       consequences, FAS 109

       generally considers all expected future events other than anticipated
       changes in the tax laws or rates.

       Foreign Currency Translation
       The Dearborn Business' predominant foreign operations are conducted in
       Belgium, Brazil, Canada, Germany, Sweden and the United Kingdom. The
       local currency in all locations except Brazil is considered to be the
       functional currency. Local currency amounts of revenues and expenses for
       all locations, except Brazil, for 1995, 1994 and 1993 were translated
       into U.S. dollars using the average exchange rates for the appropriate
       year.

       Brazil was considered a highly inflationary economy in accordance with
       Financial Accounting Standards No. 52 (FAS 52) - "Foreign Currency
       Translation". As such, the functional currency for Brazil is the U.S.
       dollar and translation gains and losses are included in current
       operations. A foreign exchange loss of $1,199, $413 and $4,440 for 1995,
       1994 and 1993, respectively, related to Brazil is reflected in other
       expense, net in the accompanying financial statements.

       Transaction gains/(losses) are recorded on transactions denominated in
       currencies other than the respective functional currencies based upon the
       difference in exchange rates from the date a transaction is initially
       recorded to the date it is settled, or the exchange rate in effect at
       December 31, 1995 and 1994, as appropriate, if it is not settled.
       Transaction gains/losses in 1995, 1994 and 1993 were not significant.

       The administrative building in Belgium sustained limited damage believed
       to be largely due to adjacent ground movement. The amount of required
       repair has not been determined, the extent of which will be dependent
       upon the Dearborn Business' planned future use of the facility. Although
       the building is insured, the factors contributing to the cause of the
       damage may limit coverage to some degree. Accordingly, the extent of
       uninsured cost, if any, is not estimable as of the date of these
       financial statements.

       At December 31, 1995, minimum future payments for noncancellable
operating leases were:

6.    Restructuring Costs

      Restructuring charges were recorded in 1995, 1994 and 1993, of $7,729,
      $4,851 and $5,608, respectively. In 1995, the restructuring charge was
      part of a worldwide Grace program aimed at streamlining processes and
      reducing selling, general and administrative expenses, factory
      administration costs and noncore corporate research and development
      expenses. The 1994 charge was part of a restructuring related principally
      to the operation in Germany and included an overall streamlining of
      processes and a reduction in the sales force. The 1993 charge consisted of
      three separate restructuring programs and included streamlining processes
      in Germany, France and other operations in Europe. It is anticipated that
      the accruals remaining at December 31, 1995 will be spent in 1996.

      $2,826 and $3,475, respectively.

       Effective August 10, 1993, in connection with the passage of the Omnibus
       Budget Reconciliation Act (OBRA), certain retroactive changes in the U.S.
       federal income tax laws were enacted, including an increase in the
       statutory income tax rate from 34% to 35% retroactively applied to
       January 1, 1993. The rate change had no material effect on deferred
       federal income taxes for 1993. No other provisions of OBRA had a material
       effect on the results of operations.

       U.S. and foreign taxes have not been provided on foreign undistributed
       earnings as such earnings are being retained indefinitely for
       reinvestment. The distribution of these earnings may result in
       additional foreign withholding taxes and additional U.S. federal
       income taxes to the extent they are not offset by foreign tax credits,
       but it is not practicable to estimate the total tax liability that
       would be incurred upon such a distribution.

8.     Pension Plans

       Grace maintains defined benefit pension plans covering employees of
       certain units, including the Dearborn Business, who meet age and service
       requirements. Benefits are generally based on final average salary and
       years of service. Grace funds its U.S. pension plan in accordance with
       federal laws and regulations. Non-U.S. pension plans are funded under a
       variety of methods dictated by differing local laws and customs and
       therefore cannot be summarized. Plan assets are invested primarily in
       common stock and fixed income securities. For purposes of these financial
       statements, other employees are considered to have

       participated in a multiemployer pension plan as defined in Statement of
       Financial Accounting Standards No. 87 (FAS 87) - "Employer's Accounting
       for Pensions." For multiemployer plans, employers are required to
       recognize as net pension expense total contributions for the period. With
       respect to these plans, the Dearborn Business charged to expense $639 and
       $304 in 1995 and 1994, respectively, and credited to income $279 in 1993.
       There were no contributions due and unpaid at December 31, 1995 and 1994.

       eligible employees in Sweden. The accrued liability related to this plan
       is $1,168 and $1,078 at December 31, 1995 and 1994, respectively. The
       Dearborn Business charged $150, $137 and $138 to expense in 1995, 1994
       and 1993, respectively, with respect to this plan.

9.     Other Postretirement Benefit Plans

       Grace provides certain other postretirement health care and life
       insurance benefits for retired U.S. employees, including the Dearborn
       Business' eligible retired employees. These retiree medical and life
       insurance plans provide various levels of benefits to employees
       (depending on their date of hire) who retire after age 55 with at least
       10 years of service. The plans are currently unfunded.

       Effective January 1, 1992, Grace adopted Statement of Financial
       Accounting Standards No. 106 (FAS 106) - "Employers' Accounting for
       Postretirement Benefits Other Than Pensions" on the immediate recognition
       basis, which requires the accrual method of accounting for the future
       costs of postretirement health care and life insurance benefits over the
       employees' years of service. The "pay as you go" method of accounting,
       used prior to 1992, recognized these costs on a cash basis. The Dearborn
       Business is considered to have participated in a multiemployer
       postretirement benefit plan as defined in FAS 106.

       For multiemployer plans, employers are required to recognize as net
       postretirement benefit costs the total contributions for the period. With
       respect to these plans, the Dearborn Business charged to expense $235,
       $254 and $194 in 1995, 1994 and 1993, respectively. There were no
       contributions due and unpaid at December 31, 1995 and 1994.

10.    Related Party Transactions and Allocations
       Cash
       The Dearborn Business utilized Grace's centralized cash management
       services. Under such service arrangements, accounts receivable were
       collected and cash was invested centrally. Additionally, cash
       disbursements were funded centrally on demand. As a result, the Dearborn
       Business maintained minimal cash balances but received or was allocated
       charges and credits to parent company investment for cash used and
       collected through these central clearinghouse arrangements.

       Intercompany sales and receivables
       The Dearborn Business sells products to Grace. Such sales totaled $292,
       $158 and $153 in 1995, 1994 and 1993, respectively, with related cost of
       goods sold of $92, $63 and $60. Intercompany receivables for these sales
       between the Dearborn Business and Grace are included in accounts and
       other receivables at December 31, 1995 and 1994.


       Corporate and Divisional Services
       Grace allocates or charges a portion of its domestic and European
       corporate expenses to its


                                      A-16

       various business units. These include Grace executive management and
       corporate overhead; postretirement benefit and pension costs; benefit
       administration; risk management/insurance administration; tax and
       treasury/cash management services; environmental services including costs
       of remediation; litigation administration services; and other support and
       executive functions.

       All of the allocations and charges described above are included in
       selling, general and administrative expenses in these financial
       statements. Such allocations and charges are based on either a direct
       cost pass through or a percentage of total costs for the services
       provided based on factors such as net sales, management time or
       headcount. Such allocations and charges totaled $4,264, $3,764 and $3,491
       for 1995, 1994 and 1993, respectively.

       Domestically, Grace also charges the Dearborn Business, based on the
       Dearborn Business' experience, for its share of workers' compensation,
       employee life, medical and dental, and other general business liability
       insurance premiums and claims handled on a corporate-wide basis. These
       charges are based upon a combination of experience and payroll dollars
       and totaled $3,625, $4,183 and $2,912 in 1995, 1994 and 1993,
       respectively, and are included in either cost of goods sold, selling,
       general and administrative expenses, or research and development
       expenses, depending upon the nature of the function. For the Dearborn
       Business' foreign operations, these costs are included in the allocated
       costs disclosed above.

       Domestic corporate research and development expenses and overheads
       directly related to the Dearborn Business of $3,468, $3,180 and $3,959 in
       1995, 1994 and 1993, respectively, have been allocated to the Dearborn
       Business and are included in research and development expenses.

       Common Manufacturing and Sales Facilities
       The Dearborn Business' Asia Pacific and Latin America operations received
       allocated overhead costs from Grace for use of shared facilities and
       resources. Such allocated general and administrative costs are based upon
       net sales and other activity factors and totaled $928, $1,015 and $964 in
       1995, 1994 and 1993, respectively.

       The manufacturing location in Sorocaba, Brazil shares land, common
       building space and support services with other operations of Grace. The
       Dearborn Business also shares administrative offices of Grace in Sao
       Paulo, Brazil and certain related administrative and accounting functions
       with Grace. The Dearborn Business is allocated costs by Grace for its
       share of occupancy costs and other administrative, maintenance, utilities
       and accounting services. Such allocated costs are based primarily on
       activity and occupancy factors. During 1995, 1994 and 1993, the Dearborn
       Business was allocated approximately $5,346, $1,844 and $839 for factory
       administration expenses and $4,014, $3,760 and $2,613 for general and
       administrative expenses, respectively.

       Management believes that the basis used for allocating corporate and
       divisional services and common manufacturing and sales facilities costs
       is reasonable. However, the terms of these transactions may differ from
       those that would result from transactions among unrelated parties.

       Corporate Accounts Receivable Sales Program
       During 1994, Grace had agreements to sell interests in designated pools
       of trade accounts receivables of the Dearborn Business. As of December
       31, 1995, the agreement had expired and no trade accounts receivables
       were sold. At December 31, 1994, $8,702 had been received pursuant to the
       sales of such trade accounts receivables, which amount has been excluded
       from the financial statements. There was no recourse to Grace or the
       Dearborn Business, nor was Grace or the Dearborn Business required to
       repurchase any of the trade accounts receivables in the pools; if certain
       trade accounts receivables in the pools proved to be uncollectible, other
       trade receivables were substituted.

11.    Parent Company Investment

       For the most part, the Dearborn Business was conducted as a division of
       Grace and not as a distinct legal entity, and accordingly there are no
       customary equity and capital accounts. Instead, parent company investment
       (i.e., of Grace) was maintained by the Dearborn Business and Grace to
       account for intercompany transactions and the net assets of the Dearborn
       Business, as more fully described in Note 1. No interest has been charged
       on the parent company investment. A summary of changes in parent company
       investment is as follows:

       Parent company investment at December 31, 1992           $131,324
          Net loss                                                (9,065)

       Parent company investment at December 31, 1994            222,642

          Net change in amount due to parent                      32,383
                                                                --------


       Parent company investment at December 31, 1995          $ 246,542
                                                               =========


12.    Commitments and Contingencies

       The Dearborn Business is subject to loss contingencies resulting from
       environmental laws and


                                      A-18

       regulations, which include obligations to remove or mitigate the effects
       on the environment of the disposal or release of certain wastes and other
       substances at various sites. The Dearborn Business accrues for
       anticipated costs associated with investigatory and remediation efforts
       where an assessment has indicated that a loss is probable and can be
       reasonably estimated. The Dearborn Business' accrued liability for
       environmental remediation totaled approximately $370 and $334 at
       December 31, 1995 and 1994, respectively.

       The measurement of the liability is evaluated based on currently
       available information, including the progress of remedial investigation
       at each site, the current status of discussions with regulatory
       authorities regarding the method and extent of remediation at each site,
       and the extent of apportionment of costs among other potentially
       responsible parties.

       The Business is subject to a number of lawsuits and claims arising out of
       the normal conduct of its business. Management and its counsel believe
       the asserted claims and identified unasserted claims are without merit
       and will vigorously defend against them.

13.    Aquatec Acquisition

       In February of 1993, the Dearborn Business purchased the water treatment
       product and services business of Aquatec Quimica S.A. and affiliated
       companies, which was located principally in Brazil. The net assets
       purchased were as follows:

          Other current assets                    $ 8,149
          Fixed assets                             11,023
          Intangibles                              51,047
          Liabilities assumed                      (9,355)
                                                  -------

              Net purchase price                  $60,864

1.   Interim Financial Data (Unaudited)

     The interim financial data at March 31, 1996 and for the three months ended
     March 31, 1996 and 1995 included in the accompanying statements are
     unaudited; however, in the opinion of the Company, the interim financial
     data include all adjustments, consisting only of normal recurring
     adjustments, necessary for a fair statement of the results for the interim
     periods. The interim financial data are not necessarily indicative of the
     results of operations for a full fiscal year.

2.   Inventories
                                               March 31, 1996

                                                  =======

     Finished goods and work in process inventories are valued at the lower of
     cost or market. Cost flow is based on the last-in, first-out (LIFO) method
     in the U.S. and first-in, first-out (FIFO) method in other regions. Raw
     materials are valued at the lower of FIFO or realizable value.

4.   Commitments and Contingencies

     The Business is subject to loss contingencies resulting from environmental
     laws and regulations, which include obligations to remove or mitigate the
     effects on the environment of the disposal, or release of certain wastes
     and other substances at various sites. The Dearborn Business accrues for
     anticipated costs associated with investigatory and remediation efforts
     where an assessment has indicated that a loss is probable and can be
     reasonably estimated. The Dearborn Business' accrued liability for
     environmental remediation totaled approximately $370 at March 31, 1996 and
     is included in parent company investment.

5.   Subsequent Events

     On June 28, 1996, Grace sold the Dearborn Business to Betz for a total
     purchase price of $636,412 (comprised of $630,000 plus an initial working
     capital adjustment of $6,412), subject to further adjustment, pursuant to
     the terms of the Agreement.

         On June 28, 1996, the Company acquired (the "Acquisition") the Dearborn
Business from Grace for $630.0 million plus a $6.4 million working capital
adjustment, subject to certain further adjustments. The Acquisition is primarily
financed by a $750 million Credit Agreement (the "Credit Agreement") among the
Company and a syndicate of banks.

         The Acquisition is accounted for using the purchase method of
accounting and, accordingly, the purchase price will be allocated to the assets
acquired and liabilities assumed based on the estimated fair value of such
assets and liabilities at the date of acquisition. The excess of the purchase
price over the fair value of the net tangible and identified intangible assets
acquired will be recorded as goodwill, which will be amortized on a
straight-line basis over 40 years. Due to the timing of the closing date, the
Company is unable to complete an initial allocation of purchase price at this
time. The unaudited pro forma results of operations are based on available
information and certain assumptions regarding the allocation of purchase price,
which could change significantly based on the results of appraisals,
finalization of the purchase price as a result of a closing date audit and other
analyses, which the Company has arranged to obtain and generally are in process.
The other analyses include, but are not limited to, actuarial studies of
employee benefit plans, the income tax effects of the Acquisition, analyses of
operations to identify assets for disposition and the evaluation of staffing
requirements necessary to meet future business needs.

         The unaudited pro forma statements of operations for the year ended
December 31, 1995 and the three months ended March 31, 1996 give effect to the
Acquisition and the Credit Agreement as if such transactions occurred as of
January 1, 1995. The financial statements of the Dearborn Business reflect the
"carve out" financial position and results of operations of the Dearborn
Business from Grace. Certain manufacturing, selling, research and administrative
expenses of Grace have been allocated to the Dearborn Business on various bases,
which, in the opinion of Grace's management, are reasonable. However, such
expenses are not necessarily indicative of, and it is not practicable to
estimate, the nature and level of expenses which might have been incurred had
the Dearborn Business been operating as a separate independent company.
Potential cost savings from combining the operations are not reflected in the
pro forma combined statement of operations because the Dearborn business may not
be fully integrated with the Company's operations until January 1998. In
addition, the Grace Dearborn Worldwide Purchase and Sale Agreement requires the
Company to make payments to Grace for certain post acquisition administrative
and toll blending services. Such payments are intended to compensate Grace for
direct and indirect costs it will incur in meeting the Company's need for such
services.

         The unaudited pro forma statements of operations should be read in
conjunction with the (i) the historical financial statements of the Company
which are included in the annual report on Form 10-K for the year ended December
31, 1995 and on Form 10-Q for the three months ended March 31, 1996, previously
filed with the Commission and (ii) the historical combined financial statements
of the Dearborn Business for the year ended December 31, 1995 and the three
months ended March 31, 1996, included herein.

         All information and financial data concerning the Dearborn Business has
been provided to the Company by Grace and are the responsibility of Grace and
the Dearborn Business. The unaudited pro forma results are not indicative of the
results that would have occurred had the Acquisition actually been consummated
on January 1, 1995, and are not intended to be a projection of future results or
trends.

         Business Employees, who are based in Japan, to become employees of

         Buyer Group shall be obligated to offer employment to such employees:
         Y. Mitsuhashi, N. Ochiai and N. Yamada. In consideration for this
         arrangement, on or promptly after the Closing, Buyer shall pay $13,000
         to Grace in reimbursement of the costs incurred by the Grace Group to
         effectuate this arrangement.

              12.16 Disabled Swedish Employee. Notwithstanding the provisions of

         employee of the Dearborn Business, shall be regarded as a disabled
         employee of a member of the Buyer Group in Sweden on and after the
         Closing Date. Grace agrees to reimburse Buyer for all costs incurred by

         the Disabled Employee, provided that, Grace shall not reimburse Buyer
         for any such costs incurred by the Buyer Group on or after the date
         that the Disabled Employee returns to active employment with the Buyer
         Group (including, but not limited to, her salary as an active
         employee). Grace shall make any reimbursement due pursuant to this
         Section 12.16 within 30 days after receipt of a written demand from
         Buyer specifying the amount of the costs incurred during a specific
         period, and appropriate supporting documentation."

         of any Selling Company of its covenant under Section 9.1 arising out of
         or relating to any alleged failure to make capital expenditures in
         accordance with the ordinary course of business for the Dearborn

         state the amount of each specific Undisclosed Employee Liability and
         Undisclosed Product Liability that was recorded as a liability in the
         Closing Net Amount. To the extent that any member of the Buyer
         Indemnified Group seeks indemnification for Damages related to an
         Undisclosed Employee Liability or Undisclosed Product Liability that
         was recorded as a liability in the Closing Net Amount, the amount of
         the Damages for which Grace is obligated to indemnify the Buyer
         Indemnified Group pursuant to Section 14.2(a) shall be reduced by the
         recorded amount for such liability as stated in the PW Letter;
         provided, however, that if such Damages are less than the recorded
         amount for such liability as stated in the PW Letter, Buyer will pay to
         Grace the difference between the recorded amount and such Damages."

to the end thereof:

        "Wherever local law requires any member of the Buyer Group to retain
        files and records in a manner that is inconsistent with the provisions
        of this Section 15.2, the record retention requirements of such local
        law shall control over the conflicting provisions of this Section
        15.2; provided that the member of the Buyer Group retaining the files
        and records shall grant reasonable access thereto to the members of
        the Grace Group."

        law shall control over the conflicting provisions of this Section 15.3;

        records shall grant reasonable access thereto to the members of the
        Buyer Group."

        Amendment No. 2, dated as of June 28, 1996, by and between W. R.
GRACE & CO.-CONN. ("Grace") and BETZ LABORATORIES, INC. ("Buyer").

                                  WITNESSETH:

        WHEREAS, Grace and Buyer have entered into the Grace Dearborn Worldwide
Purchase and Sale Agreement (the "Sale Agreement") dated as of March 11, 1996
providing for the sale to Buyer by Grace of the Dearborn Business (as defined
therein) including, inter alia, the 51% interest owned by Grace in Dearborn IEI
Ltd. (the "Dearborn India JV"), a joint venture between Grace and Ion Exchange
(India) Ltd. ("IEI") that was established under a Joint Venture Agreement dated
September 16, 1994 (the "Joint Venture Agreement");

        WHEREAS, the terms of the Joint Venture Agreement are unacceptable to
Buyer unless modified by agreement with IEI;

        WHEREAS, Buyer has advised Grace that it has not yet determined whether
it would be willing to acquire Grace's interest in the Dearborn India JV on
modified terms and, subject thereto, Grace is willing to retain such interest on
the terms and conditions of this agreement;

        WHEREAS, in connection with the formation of the Dearborn India JV,
Grace and the Dearborn India JV entered into a Technical Know-How License
Agreement, a Trade Mark License Agreement and a Corporate Name and Logo License
Agreement (collectively, the "License Agreements") providing, inter alia, for
licenses from Grace to the Dearborn India JV of certain patents, technology and
trademarks, including the name "Dearborn", that are being transferred by Grace
to Buyer on the date hereof pursuant to the Sale Agreement; and

        WHEREAS, pursuant to Section 19.6 of the Sale Agreement, Grace and Buyer
wish to amend certain provisions of the Sale Agreement in the manner set forth
herein to provide for the retention by Grace of its interest in the Dearborn
India JV;

        NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein, Grace and Buyer hereby agree as
follows:

        1. Except as otherwise specifically provided herein, all capitalized
terms used in this agreement shall have the respective meanings given to such
terms in the Sale Agreement.

<PAGE>


        2. All Article and Section numbers and Schedule and Exhibit references
used in this agreement refer to Articles and Sections of the Sale Agreement and
Schedules and Exhibits attached thereto or delivered simultaneously therewith,
unless otherwise specifically described.

        3. (a) Buyer shall have an irrevocable option (the "Option") to acquire
Grace's interest in the Dearborn India JV during the period commencing on the
date of this agreement and ending at 5:30 p.m., Eastern Daylight Time on July
12, 1996 (the "Option Period"). The Option may be exercised by Buyer by giving
written notice of exercise to Grace prior to the expiration of the Option Period
in the manner set forth in Section 11 of this agreement.

        (b) If the Option is exercised, Grace and Buyer, or a member of the
Buyer Group designated by Buyer, shall promptly enter into a Share Purchase
Agreement (the "Share Purchase Agreement") providing for (1) the transfer to
Buyer for no additional consideration of Grace's 51% interest in the Dearborn
India JV effective upon the date that receipt of all necessary consents and
approvals to the transfer have been obtained (the "Effective Date") including,
without limitation, the consent of IEI, the approval of the Board of Directors
of the Dearborn India JV, and the consent of the Reserve Bank of India under the
provisions of Section 29(1)(b) of the Foreign Exchange Regulation Act, 1973,
and (2) the assumption by Buyer of Grace's liabilities and obligations that
pertain primarily to the Dearborn India JV including Grace's liabilities and
obligations under the Joint Venture Agreement and the License Agreements, except
as otherwise provided in subsection (c) of this Section 3. The Share Purchase
Agreement shall permit either Grace or Buyer to terminate its obligations
thereunder if Buyer is unable to obtain all such consents, after reasonable best
efforts to do so, by November 1, 1996. In the event that either Grace or Buyer
terminates the Share Purchase Agreement as provided in this subsection (b),
Buyer shall indemnify Grace and hold Grace harmless from any out-of pocket costs
incurred by Grace in connection with the termination of the Dearborn India JV in
accordance with Section 7 and for any increase in the amount of the debt of the
Dearborn India JV for which Grace is liable under the Guarantee or otherwise,
during the period commencing on July 13, 1996 and ending on the earlier of the
Effective Date or the date the Share Purchase Agreement is terminated.

        (c) Except as provided in the last sentence of sub-section (b) of
Section 3, Buyer shall not assume and shall have no obligation to reimburse
Grace for any amount paid by Grace to discharge its obligations to guarantee or
otherwise discharge any debt of the Dearborn India JV, including without

        4. Notwithstanding the provisions of the Sale Agreement, and except as
otherwise provided in Section 3 of this Agreement,

        (a) Grace shall not convey to any of the Buying Companies the
Transferred Investment or any of Grace's other rights or interests with respect
to the Dearborn India JV;

        (b) The Buying Companies shall not purchase from Grace the Transferred
Investment or any of Grace's other rights or interests with respect to the
Dearborn India JV, nor shall any of the Buying Companies assume any liabilities
or obligations of any member of the Grace Group with respect thereto;

        (c) After the expiration of the Option Period, Grace shall have the
right to retain or dispose of the Transferred Investment and its other rights
and interests with respect to the Dearborn India JV in its sole discretion; and

        (d) Grace's retention or subsequent disposition of the Transferred
Investment shall not result in any reduction of the Total Purchase Price
pursuant to Section 4.C.

        5. The provisions of Section 8.8 shall not apply to the Dearborn India
JV nor to Grace's retention of its ownership interest therein, nor to any
activities undertaken by any member of the Grace Group in making additional
investments in the Dearborn India JV, or in managing or operating the Dearborn
India JV after the Closing in competition with Buyer in India or in any other
country in which the Dearborn India JV is presently licensed to operate pursuant
to the License Agreements using patents, technology or trademarks that are being
transferred by Grace to Buyer pursuant to the Sale Agreement. Simultaneously
with the execution and delivery of this agreement, Buyer and Grace are entering
into an Intellectual Property License Agreement Relating to Dearborn IEI India
Water Treatment Joint Venture pursuant to which Buyer is granting to Grace
certain rights in such patents, technology and trademarks in order to permit
Grace to satisfy its obligations under the JV Agreement and the License
Agreements. Such license will terminate upon the closing of the purchase by
Buyer of Grace's interest in the Dearborn India JV and Buyer's assumption of
Grace's obligations under the License Agreements or the termination of the JV
Agreement under circumstances where Grace is no longer obligated to continue to
provide such rights. Grace agrees not to make any amendments to the License
Agreements or the JV Agreement that would result in any increase in the rights
of the Dearborn India JV to any of the intellectual property rights of the Buyer
or Buyer's Subsidiaries including the intellectual property rights conveyed by
Grace to Buyer pursuant to the Sale Agreement.

        7. In the event that Grace arranges for the termination of the Dearborn
India JV either in accordance with the terms of the JV Agreement (other than as
a result of a breach thereof by Grace) or pursuant to an agreement with IEI,
Buyer shall reimburse

                                     - 3 -
<PAGE>


Grace for all documented out-of-pocket costs incurred by Grace in connection
with such termination including any payments to IEI or other Persons for which
Grace is responsible under the terms of the JV Agreement or the License
Agreements, provided, however, that Buyer's total obligation hereunder shall not
exceed $500,000 without Buyer's written consent, and provided further that Buyer
shall have no obligation to reimburse Grace for any amount paid by Grace to
discharge its obligation to guarantee or otherwise discharge any debt of the
Dearborn India JV including, without limitation, the Guarantee, except as
provided in the last sentence of Sub-section (b) of Section 3.

        8. The provisions of Article 12 shall not apply to the employees of the
Dearborn India JV.

        9. All references in Articles 5, 14, 15 and 16 to "Transferred Joint
Venture" shall be deemed to refer only to the Dearborn Japan JV. Other
provisions of the Sale Agreement that contemplate the transfer of the
Transferred Investment from Grace to the Buying Companies shall be disregarded
to the extent such provisions are inconsistent with this agreement.

        10. Grace shall not agree to any amendment to the JV Agreement without
Buyer's prior written consent, (a) during the Option Period, and (b), if Buyer
exercises the Option, during the period commencing on the date the Option is
exercised and ending on the earlier of the Effective Date or the date the Share
Purchase Agreement is terminated.

        11. All notices, requests, demands and other communications required or
permitted to be given under this agreement shall be deemed to have been duly
given if in writing and delivered personally, by reputable overnight courier
service, by telephone facsimile transmission (as evidenced by a confirmed
receipt), or by first-class, postage prepaid, registered or certified mail,

thereto.

        (b) 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.

        (c) Each of Grace and Buyer hereby irrevocably submits in any suit,
action or proceeding arising out of or relating to this agreement, or any of its

hereunder, 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.

        (d) This agreement shall not be assignable by either party hereto
without the prior written consent of the other. This agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns, except that Buyer may assign its right to
purchase Grace's interest in the Dearborn India JV to a subsidiary of Buyer
without relieving Buyer of its obligations under this agreement.

        (e) 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.

        IN WITNESS WHEREOF, the parties have executed this Amendment No. 2 on
the date first above written.
