                        PRO FORMA FINANCIAL INFORMATION
 
UNAUDITED PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET
 
     The unaudited pro forma condensed consolidated balance sheet of New Grace
has been derived from the historical consolidated balance sheet of Grace New
York, adjusted for the disposition of NMC and for certain costs and expenses to
be incurred in connection with the Reorganization. The pro forma condensed
consolidated balance sheet has been prepared on the assumption that the
Reorganization occurred on March 31, 1996.
 
     The pro forma condensed consolidated balance sheet should be read in
conjunction with the Consolidated Financial Statements and the First Quarter
Financial Statements. The pro forma condensed consolidated balance sheet is not
necessarily indicative of the financial position of New Grace that would
actually have resulted had the Reorganization occurred on March 31, 1996.

expense expected to result from the Reorganization. The pro forma condensed
consolidated statement of operations has been prepared on the assumption that
the Reorganization occurred on January 1, 1995.
 
     The pro forma condensed consolidated statement of operations should be read
in conjunction with the Consolidated Financial Statements and the First Quarter

operations is not necessarily indicative of the results of operations of New
Grace that would actually have resulted had the Reorganization occurred on

     NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET AND
                            STATEMENT OF OPERATIONS
                (DOLLARS IN MILLIONS, EXCEPT PER SHARE AMOUNTS)
 
(a) The Reorganization Agreement provides that, prior to the Reorganization, NMC
    will borrow and/or will assume debt of Grace Chemicals in an aggregate
    amount of approximately $2,263 (as adjusted pursuant to the Reorganization
    Agreement), and will distribute the net cash proceeds to Grace Chemicals; it
    is currently estimated that such aggregate amount will be approximately
    $2,247.8. A portion of such net cash proceeds will be applied to further
    reduce Grace Chemicals' debt, resulting in an aggregate reduction of
    $1,187.8 in Grace Chemicals' debt (see note (b) below). In addition, Grace
    will incur expenses totaling approximately $60.0 (net of applicable tax
    benefit) in connection with the Reorganization. The remaining net cash
    proceeds received from NMC (estimated at $1,000.0) are expected to be used
    to purchase shares of New Grace Common Stock, which would result in a
    decrease in current assets and a commensurate decrease in shareholders'
    equity.
 
(b) As discussed in note (a) above, the assumption of Grace Chemicals' debt by
    NMC and the application of a portion of the net cash proceeds distributed to
    Grace Chemicals by NMC to the reduction of Grace Chemicals' debt is expected
    to result in an aggregate reduction of $1,187.8 in Grace Chemicals' debt,
    consisting of (i) $179.8 of borrowings under NMC receivables financing
    arrangements; (ii) $186.5 of other NMC debt; and (iii) $821.5 of short-term
    debt (consisting of $527.3 of commercial paper and bank borrowings and
    $294.2 of other short-term borrowings).
 
(c) Reflects the disposition of NMC's net assets of $1,842.6. Subsequent to the
    disposition of NMC, New Grace will retain as discontinued operations certain
    health care assets, primarily a bioseparation sciences business, a health
    care services company and other assets (including NMC's cash and marketable
    securities). The resulting gain of $405.2 (reflecting net cash proceeds of
    $2,247.8, as described in note (a) above, less the disposition of NMC's net
    assets of $1,842.6) is not reflected in the pro forma condensed consolidated
    statement of operations.
 
(d) As part of the Reorganization, Grace New York will distribute, on a
    one-share-for-one-share basis, all of the issued and outstanding New Grace
    Common Stock (which has a par value of $.01 per share) to the holders of
    shares of Grace New York Common Stock (which has a par value of $1.00 per
    share) at the Time of Distribution. The treasury stock held by Grace New
    York at the Time of Distribution will not be transferred to New Grace and is
    therefore eliminated in the pro forma adjustments. As a result of the
    retirement of the treasury stock and the difference in the par values, (i)
    the $2.4 of treasury stock will be eliminated, (ii) Common stock will
    decrease by $97.5 and (iii) paid in capital will increase by $95.1.
 
(e) The currently issued and outstanding shares of Grace New York Preferred
    Stock will remain issued and outstanding following the Reorganization and
    the Distribution, and no New Grace preferred stock will be issued. The
    resulting reduction in outstanding Preferred stock is presented as an
    increase in retained earnings within the shareholders' equity section of the
    pro forma balance sheet.
 
(f) Grace Chemicals has allocated interest expense to discontinued operations
    (including NMC), based on the ratio of the net assets of the businesses
    classified as discontinued operations as compared to Grace Chemicals' total
    capital. Excluding amounts allocated to discontinued operations, interest
    expense and related financing costs were $71.3 for the year ended December
    31, 1995 and $18.4 for the three months ended March 31, 1996. For the year
    ended December 31, 1995, the assumed reduction in debt as of January 1, 1995
    would have the pro forma effect of reducing total interest expense and
    related financing costs by $94.2 (of which $0.7 was attributable to
    continuing operations and $93.5 was attributable to discontinued
    operations). For the three months ended March 31, 1996, the assumed
    reduction in debt as of January 1, 1995 would have the pro forma effect of
    reducing total interest expense and related financing costs by $21.2
    (increasing interest expense and related financing costs attributable to
    continuing operations by $5.6 and reducing interest expense and related
    financing costs attributable to discontinued operations by $26.8).

     The above adjustments to interest expense and related financing costs would
     have the pro forma effect of increasing tax expense by $0.3 for the year
     ended December 31, 1995 and reducing tax expense by $2.2 for the
     three-month period ended March 31, 1996. The tax effects were calculated
     using an effective tax rate of approximately 40%, which represents the U.S.
     federal corporate tax rate of 35%, plus state and local income taxes, net
     of U.S. federal income tax benefit.

                            ------------------------
 
     For accounting purposes, Grace Chemicals will receive the Distribution
Payment and will be deemed to receive a 44.8% common equity interest in FMC and
to immediately distribute such interest to the holders of Grace New York Common
Stock; however, the receipt and distribution of the interest in FMC Ordinary
Shares are not reflected in the pro forma condensed consolidated balance sheet
and statement of operations.
 
     In March 1996, Grace Chemicals entered into a definitive agreement to sell
its Grace Dearborn water treatment and process chemicals business to Betz
Laboratories, Inc. for $632 million. The transaction was completed in June 1996.
Grace Dearborn's sales and revenues were $398.5 million for the year ended
December 31, 1995; its financial position and results of operations were not
significant to Grace Chemicals. Also, in May 1996 Grace Chemicals completed the
sale of the transgenic plant business of its Agracetus, Inc. subsidiary (which
had previously been classified as a discontinued operation) to the Monsanto
Company for $150 million; the revenues and net assets of Agracetus, Inc. were
immaterial to Grace Chemicals. The after-tax cash proceeds generated by these
transactions have been applied to the further reduction of borrowings and the
repurchase of stock. These transactions are not reflected in the pro forma
financial information included herein.
 
     In May 1996, Grace Chemicals entered into a new credit agreement providing
for total borrowings of $1.85 billion, and three previous agreements providing
for total borrowings of $850 million were terminated. The new credit agreement
is intended to provide liquidity to finance the repurchase of stock and
potential acquisitions. The borrowings under the new credit agreement have been
guaranteed by New Grace and Grace New York. Upon the completion of the
transactions described above (including the Reorganization), the total
borrowings available under the new credit agreement will be reduced to $650
million and the guarantee by Grace New York will be terminated.
