             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, 2004 and 2003, 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.

W. R. GRACE & CO.
SAVINGS AND INVESTMENT PLAN
NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

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"). 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.

     CONTRIBUTIONS

     Effective July 1, 2004, participants may elect to contribute to the Plan 2%
     to 25% 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)). Prior to
     July 1, 2004, participants could elect to contribute to the Plan 2% to 16%
     of their compensation, as defined.

     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 $13,000 and $12,000 for 2004 and 2003,
     respectively. Federal income tax law limited the annual compensation on
     which tax-qualified plan benefits may be based to $205,000 and $200,000 for
     2004 and 2003, respectively.

     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.

W. R. GRACE & CO.
SAVINGS AND INVESTMENT PLAN
NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

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

     The Plan offers 27 mutual funds and a Fixed Income Fund comprised
     principally of guaranteed investment contracts as investment options for
     participants. The Plan offered Grace Common Stock as an investment option
     for participants until February 27, 2004.

     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.

     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 and Investment Plan. The
     Bankruptcy Court approved the retention of State Street. In February 2004,
     State Street commenced selling Grace common stock on the open market. Under
     this selling program, State Street directed the sale of approximately
     932,000 shares of Grace common stock (ranging in price from $2.75 to $3.19
     per share) on the open market and further negotiated and executed the sale
     of all of the remaining shares (approximately 6,273,000) of Grace common
     stock on April 16, 2004 at a price of $3.50 per share. In addition,
     approximately 935,000 shares were sold in participant-directed transactions
     during the period from January 1, 2004 through April 7, 2004.

     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 limited to the vested 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.

     Active loans bear interest rates that range from 6.0% to 11.5% with
     maturity dates ranging from 2005 through 2024. 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. Interest
     income is accrued when earned.

     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. 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. At December 31, 2003 the value of Grace's
     common stock was $2.57 per share. On April 16, 2004 State Street sold all
     the remaining shares of Grace common stock at a price of $3.50 per share;
     see Note 1 for further information.

     The Plan presents in the Statement of Changes in Net Assets Available for
     Benefits the net appreciation 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.

     RECLASSIFICATIONS

     Certain amounts in prior years' Financial Statements have been reclassified
     to conform to the 2004 presentation.

     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 and changes therein, and
     disclosures of contingent 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 participants'
     account balances and 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 interest, 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 Fidelity.
     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 $64,252 and
     $236,995 for the years ended December 31, 2004 and 2003, respectively.

     Grace, as Plan sponsor, is also a related party. The Grace Common Stock
     Fund included shares of Grace common stock. At December 31, 2004, no shares
     of Grace common stock were held. At December 31, 2003, the Plan held
     8,140,484 shares of Grace common stock. The fair value of the Grace Common
     Stock Fund was $20,921,043 at December 31, 2003. No purchases were made
     during 2004. Purchases of $19,596,606 (9,289,777 shares) were made during
     2003. Sales of $27,398,844 (8,140,484 shares) and $3,640,434 (1,149,295
     shares) of Grace common stock were made during 2004 and 2003, respectively.

6.   FEDERAL INCOME TAXES

     On August 8, 2003, the Internal Revenue Service ("IRS") issued a
     determination 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.   LEGAL PROCEEDINGS

     In June 2004, a purported class action complaint (Evans v. Akers et al.)
     was filed in U.S. District Court for the District of Massachusetts against
     Grace's Board of Directors, certain current and former Grace officers and
     employees, and others, relating to the Plan. The complaint alleges that the
     decline in the price of Grace common stock from July 1999 through February
     2004 resulted in significant losses to Plan participants. The complaint
     further alleges that the defendants breached their fiduciary duties under
     the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
     by failing to sell or take other appropriate action with regard to Grace
     common stock held by the Plan during that period, and by failing to
     disclose to Plan participants the risk of investing in Grace common stock.
     The complaint seeks compensatory damages for the Plan from the defendants.

     On October 26, 2004, a purported class action complaint (Bunch et al. v. W.
     R. Grace & Co. et al.) also related to the Plan was filed in the U.S.
     District Court for the Eastern District of Kentucky against Grace, the
     Grace Investment and Benefits Committee, Grace's Board of Directors,
     certain current and former Grace officers and employees, and others. The
     complaint alleges that Grace and its investment advisors breached fiduciary
     duties under ERISA by selling Grace common stock from the Plan at a
     distressed price. The complaint further alleges that Grace breached
     fiduciary duties under ERISA by hiring State Street Bank and Trust Company,
     the investment manager for the Plan

     that was retained by Grace in December 2003, to rapidly liquidate all of
     the employees' Grace common stock investment at an artificially low sales
     price.

     The defendants in these cases have moved to transfer the Bunch action to
     the U.S. District Court for the District of Massachusetts and will seek to
     consolidate it with the Evans action. Grace likely would have an obligation
     to indemnify the other defendants for any liability arising out of either
     of these lawsuits. However, Grace believes that the allegations in both
     lawsuits are without merit and that, in any event, any liability arising
     therefrom would be covered by its fiduciary liability insurance.

9.   SUBSEQUENT EVENTS

     In August 2004, Grace, through its subsidiary The Separations Group,
     acquired Alltech International Holdings, Inc. As a result of this
     acquisition, the assets from the Alltech Associates, Inc. Employees' Profit
     Sharing Plan and Trust will be transferred to the W. R. Grace & Co. Savings
     and Investment Plan during the third quarter of 2005.

     Beginning March 28, 2005 a terminated participant with a balance greater
     than $1,000 and less than $5,000 will be directly rolled over to an IRA
     account with Fidelity.
