ITEM 2.                    IDENTITY AND BACKGROUND.

                           Item 2 is amended and restated as follows:

                           FNMC, a New York corporation, was the parent company
                           of New Grace, which was incorporated for the purpose
                           described in the Joint Proxy Statement - Prospectus
                           of Fresenius Medical Care AG, FNMC and Fresenius USA,
                           Inc. dated August 2, 1996 ("Proxy Statement-
                           Prospectus"). On September 28, 1996, FNMC spun off to
                           its shareholders 100% of the shares in New Grace held
                           by FNMC. Holders of record of common stock of FNMC,
                           par value $1.00 per share ("FNMC Common Stock") as of
                           the close of business on September 27, 1996, received
                           one share of New Common Stock for each share of FNMC
                           Common Stock held. The principal business and office
                           address of FNMC is Reservoir Place, 1601 Trapelo
                           Road, Waltham, Massachusetts 02154.

                           In the last five years, FNMC has not been convicted
                           in a criminal proceeding (excluding traffic
                           violations and similar misdemeanors), nor has FNMC
                           been a party to a civil proceeding as a result of
                           which FNMC was or is subject to a judgment, decree or
                           final order enjoining future violations of, or
                           prohibiting or mandating activities subject to,
                           federal or state securities laws or finding any
                           violation with respect to such laws. (However, see
                           "BUSINESS OF FRESENIUS MEDICAL CARE -- Regulatory and
                           Legal Matters -- Legal and Regulatory Proceedings" in
                           the Proxy Statement-Prospectus referred to below for
                           information regarding certain investigations of FNMC
                           being conducted by the Securities and Exchange
                           Commission.)

                           Information concerning each director and executive
                           officer of FNMC is set forth in Schedule A to this
                           Amendment. In the last five years, none of such
                           persons has been convicted in a criminal proceeding
                           (excluding traffic violations and similar
                           misdemeanors), nor has any of such persons been a
                           party to a civil proceeding as a result of which such
                           person was or is subject to a judgment, decree or
                           final order enjoining future violations of, or
                           prohibiting or mandating activities

                           subject to, federal or state securities laws or
                           finding any violation with respect to such laws.

ITEM 3.                    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

                           Item 3 is amended and restated as follows:

                           FNMC owned 1,000 shares of New Grace's common stock
                           par value $1.00 per share ("Old Common Stock"), which
                           represented all of the authorized, issued and
                           outstanding shares of Old Common Stock. FNMC paid
                           $1,000 out of its internally generated funds to New
                           Grace for such shares. No part of the purchase price
                           was represented by funds or other consideration
                           borrowed or otherwise obtained for the purpose of
                           acquiring, holding, trading or voting the securities.

ITEM 4.                    PURPOSE OF TRANSACTION.

                           Item 4 is hereby amended and restated as follows:

                           As described in Item 2 above, New Grace was
                           incorporated by FNMC for the purposes described in
                           the Proxy Statement-Prospectus. Upon completion of
                           the transactions described in the Proxy Statement-
                           Prospectus, the Old Common Stock was recapitalized as
                           New Common Stock, all of the issued and outstanding
                           shares of such recapitalized New Common Stock were
                           distributed to the holders of FNMC Common Stock on a
                           one-for-one basis, and the name of New Grace was
                           changed to "W. R. Grace & Co." See the Proxy
                           Statement-Prospectus, which is incorporated herein
                           by reference, for further information.

                           Other than as described herein and in the Proxy
                           Statement-Prospectus, FNMC has no plans or proposals

                                        liquidation, involving New Grace or any
                                        of its subsidiaries;

                                    (h) causing a class of securities of New

                                        12(g)(4) of the Securities Exchange Act
                                        of 1934; or

                                    (j) any action similar to any of those
                                        enumerated above.

ITEM 5.                    INTEREST IN SECURITIES OF THE ISSUER.

                           Item 5 is amended and restated as follows:

                           Neither FNMC nor any director or executive officer of
                           FNMC beneficially owns any shares of the Old Common
                           Stock. As described in Item 2 above, on September 28,
                           1996, the Old Common Stock held by FNMC was
                           recapitalized as New Common Stock and distributed to
                           the holders of FNMC Common Stock. No director or
                           executive officer of FNMC has effected any
                           transactions in the Old Common Stock during the past
                           60 days.

                           FNMC ceased to be the beneficial owner of more than
                           five percent of the Old Common Stock on September 28,
                           1996.

ITEM 6.                    CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR 
                           RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE 
                           ISSUER.

                           Item 6 is amended and restated as follows:

                           Other than as described in the Proxy
                           Statement-Prospectus, FNMC has no contracts,
                           arrangements, understandings or relationships with
                           respect to New Grace's securities.
