             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Participants and Administrative Committee of the
W. R. Grace & Co. Savings and Investment Plan:

In our opinion, the accompanying statements of net assets available for benefits
and the related statements of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the W. R. Grace & Co. Savings and Investment Plan (the "Plan"), at December
31, 2003 and 2002, and the changes in net assets available for benefits for the
years then ended in conformity with accounting principles generally accepted in
the United States of America. These financial statements are the responsibility
of the Plan's management. 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 the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, 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 our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental Schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan's Management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

--------------------------------------------------------------------------------


1.    DESCRIPTION OF THE PLAN

      The following description of the W. R. Grace & Co. Savings and Investment
      Plan (the "Plan") provides only general information. Participants should
      refer to the text of the Plan, the Summary Plan Description, and the
      Prospectus Supplement for the Plan for more complete information.

      GENERAL

      On April 2, 2001, W. R. Grace & Co. ("Grace") and 61 of its U.S.
      subsidiaries and affiliates (collectively, the "Company") filed voluntary
      petitions for reorganization under Chapter 11 of the Bankruptcy Code in
      the United States Bankruptcy Court for the District of Delaware. The
      Bankruptcy Court approved on April 2, 2001 an order that authorized the
      debtors and debtors in possession under the bankruptcy filing, to pay, in
      their sole discretion, employee benefits, including employer contributions
      under the Plan. Under the Court's authorization, Grace has continued to
      meet its obligations under the Plan. Should the Plan terminate as a result
      of Chapter 11 proceedings, Company contributions would cease and the net
      assets of the Plan would be distributed in accordance with the provisions
      of the documents governing the Plan.

      The Plan is a defined contribution plan originally adopted effective
      September 1, 1976, and has been amended from time to time. The Plan is
      subject to certain provisions of the Employee Retirement Income Security
      Act of 1974, as amended ("ERISA"). Fidelity Management Trust Company
      ("Fidelity" or "Trustee") administers the Plan's recordkeeping and serves
      as the Plan's trustee and custodian.


      ELIGIBILITY AND VESTING

      Any salaried and hourly employee of Grace or its U.S. subsidiaries who is
      in an eligible employment classification and who has completed three
      months of service is eligible for participation.

      A participant's interest (employee contributions, Company contributions,
      and earnings thereon) in the Plan is always fully vested.

SAVINGS AND INVESTMENT PLAN

--------------------------------------------------------------------------------


      CONTRIBUTIONS

      Each year, participants may elect to contribute to the Plan 2% to 16% of
      their compensation (which, for purposes of the Plan, consists of salary
      and/or commissions, incentive compensation, and bonus awards (excluding
      long-term incentive bonuses and retention bonuses)).

      Participant contributions may be made from before-tax and/or after-tax
      income, as provided under Sections 401(k) and 401(m) of the Internal
      Revenue Code of 1986, as amended (the "Code"), subject to an annual dollar
      limit on before-tax contributions of $12,000 and $11,000 for 2003 and
      2002, respectively. Federal income tax law limited the annual compensation
      on which tax-qualified plan benefits may be based to $200,000 for 2003 and
      2002.

      The Company contributes 100% of the first 6% of base compensation that a
      participant contributes to the Plan. Therefore, the maximum Company
      contribution is 6% of a participant's compensation.

      Company contributions are allocated to investment options in accordance
      with the participant's investment election.

      The Plan offers 27 mutual funds, Grace Common Stock, and a Fixed Income
      Fund comprised principally of guaranteed investment contracts as
      investment options for participants.

      The Plan provides that a statement of each participant's account be sent
      to the participant not less frequently than once in each Plan year.

      Additionally, on any business day, participants may allocate their future
      contributions among any of the investment options and may transfer the
      amounts related to their prior contributions in any of the investment
      options to other investment options. All investment options are
      participant-directed.

      PARTICIPANT ACCOUNTS

      Each participant's account is credited with the participant's
      contribution, the applicable allocation of the Company's contribution, and
      an appropriate allocation of Plan earnings (losses), and charged with an
      allocation for administrative expenses. Allocations are based on
      participant earnings or account balances, as defined. The benefit to which
      a participant is entitled is the benefit that can be provided from the
      participant's account.

      PARTICIPANT LOANS

      Participants may borrow up to one-half of the value of their account
      balance up to $50,000. Loans may be for a term of one to five years for a
      general-purpose loan and up to twenty years for a loan to purchase a
      principal residence. The interest rate on the loan is set on the
      application date and equals the prime interest rate on the last business
      day of the preceding calendar quarter plus 2 percent. The interest rate
      and repayment amounts for the loans are fixed for the term of the loan;
      loans are repaid in periodic installments, depending on the loan
      provisions. Participants can repay the outstanding loan balance in full at
      any time without penalty. Loans are considered to be in default and
      treated as a distribution for tax purposes if no payment is received for
      ninety days. If employment with the Company ends, any outstanding loan
      balance will be considered a distribution if not repaid within ninety
      days.

SAVINGS AND INVESTMENT PLAN
NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------


      Interest paid on loans is credited to the individual investment options
      from which the loan was taken.

      PAYMENT OF BENEFITS

      Upon disability, retirement, or other termination of service, a
      participant who is not eligible to elect or who does not elect to defer
      the distribution may elect to receive his/her vested benefit in the form
      of a single lump sum payment or annual or quarterly installment payments
      if the vested balance exceeds $5,000. For amounts less than $5,000, a
      single lump sum payment is made.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The accounts of the Plan are maintained on the accrual basis of
      accounting, which is acceptable under U.S. Department of Labor Regulations
      and is in accordance with accounting principles generally accepted in the
      United States of America ("GAAP").

      INVESTMENT VALUATION AND INCOME RECOGNITION

      Investments in publicly traded securities and mutual funds are stated at
      fair value. Investments in publicly traded securities are valued at the
      last reported sales price on the last day of the year. Shares of mutual
      funds are valued at the net asset value of shares held by the Plan at
      year-end. Investments in guaranteed investment contracts held in the Fixed
      Income Fund (see Note 4) are stated at contract value, which represents
      contributions made under the contract plus interest at the contract rate,
      less funds used for withdrawals. Participant loans are valued at cost,
      which approximates fair value.

      Purchases and sales of publicly traded securities are recorded on a
      trade-date basis. Dividends are recorded on the ex-dividend date.

      Income of each investment option is reinvested in that option. Investment
      management of the Fixed Income Fund and investment oversight of the
      Fidelity Mutual Funds is the responsibility of the Investment and Benefits
      Committee appointed by the Grace Board of Directors, or as delegated by
      that Committee.

      Prior to April 14, 2003, the Plan recorded a realized gain or loss on
      Grace Common Stock Fund units distributed to participants in an amount
      equal to the difference between the market value at the distribution date
      and the average cost of the units distributed. The cost of securities sold
      was determined on the basis of average cost, and a gain or loss was
      recorded equal to the difference between average cost and the sale price.
      Accordingly, participants held units in the fund and not shares, the value
      of which was $1.02 per unit at December 31, 2002, versus Grace common
      stock which was valued at $1.96 per share at December 31, 2002. On April
      14, 2003, the Grace Stock Fund converted from the unitized method of
      trading to real time trading, which allowed participants to sell Grace
      common stock by directly submitting orders to the stock market.
      Accordingly, effective April 14, 2003, participants held shares rather
      than units of Grace common stock, the value of which was $2.57 per share
      at December 31, 2003.

      The Plan presents in the Statement of Changes in Net Assets Available for
      Benefits the net appreciation (depreciation) in the fair value of its
      investments, which consists of the realized gains or losses and the
      unrealized appreciation (depreciation) on those investments.

      PAYMENT OF BENEFITS

      The Plan recognizes benefits when paid.

      USE OF ESTIMATES

      The preparation of financial statements in conformity with GAAP requires
      the Plan fiduciaries to make estimates and assumptions that affect the
      reported amounts of assets and liabilities on the date of the financial
      statements. Actual amounts may differ from the estimates used.

      RISKS AND UNCERTAINTIES

      The Plan provides for various investment options. Investments are exposed
      to various risks, such as interest, market, and credit risks. Due to the
      level of risk associated with certain investments, it is at least
      reasonably possible that changes in the values of investments will occur
      in the near term and that such changes could materially affect the amounts
      reported in the Statement of Net Assets Available for Benefits.

4.    GUARANTEED INVESTMENT CONTRACTS

      Investments in the participant-directed Fixed Income Fund consist
      primarily of benefit-responsive guaranteed investment contracts ("GICs")
      issued by various insurance companies. The Plan's GICs are stated at
      contract value, which approximates fair value. Contract value includes
      principal invested, plus earnings, less benefit payments and
      administrative expenses. Listed below are the Plan's investments in GICs:

5.    RELATED-PARTY TRANSACTIONS

      Certain Plan investments are shares of mutual funds managed by the
      Fidelity Management Trust Company. Fidelity is the trustee as defined by
      the Plan, and, therefore, these transactions qualify as party-in-interest
      transactions. Fees paid by the Plan for the investment management services
      amounted to $236,995 and $229,290 for the years ended December 31, 2003
      and 2002, respectively.

      W. R. Grace & Co., as plan sponsor, is also a related party. The Grace
      Common Stock Fund includes shares of Grace common stock. At December 31,
      2003 and 2002, the Plan held 8,140,484 shares and 23,703,537 units of
      Grace stock, respectively. The fair value of the Grace Common Stock Fund
      was $20,921,043 and $24,101,477 at December 31, 2003 and 2002,
      respectively. Purchases of $19,596,606 (9,289,777 shares) and $15,229,192
      (13,838,034 units) and sales of $3,640,434 (1,149,295 shares) and
      $13,265,186 (11,303,050 units) of Grace common stock were made during 2003
      and 2002, respectively.

6.    FEDERAL INCOME TAXES

      On August 8, 2003, the Internal Revenue Service ("IRS") issued a letter
      stating that the Plan, as then in effect, was in compliance with the
      applicable requirements of the Code. The Plan has been amended since
      the issuance of this determination letter; however, Grace believes that
      the Plan remains in compliance with those requirements.

7.    PLAN TERMINATION

      Grace anticipates that the Plan will continue indefinitely, but reserves
      the right to amend or discontinue the Plan at any time. A participating
      business unit may terminate its participation in the Plan with the
      approval of Grace's Board of Directors. In the event the Plan terminates,
      participants would receive the value of their account balances at the time
      of distribution.

8.    MANAGEMENT OF GRACE COMMON STOCK

      On December 15, 2003, Grace retained State Street Bank and Trust Company
      ("State Street") to act as the investment manager and independent
      fiduciary of the Grace Common Stock within the Grace Savings & Investment
      Plan. The United States Bankruptcy Court for the District of Delaware
      approved the retention of State Street. In February 2004, State Street
      commenced selling Grace common stock on the open market. Under this
      selling program, just over 930,000 shares of Grace common stock were sold
      on the open market. State Street further negotiated and executed the sale
      of all of the remaining shares (6,272,117) of Grace common stock on April
      16, 2004 at a price of $3.50 per share.

9.    SUBSEQUENT EVENTS

      On July 1, 2004, the maximum contribution percentage for Participants will
      increase from 16% to 25%.
