ITEM 1. CHANGES IN CONTROL OF THE REGISTRANT

         On September 30, 1996 (the "Effective Date"), the Registrant completed
the reorganization (the "Reorganization") described in the Joint Proxy
Statement-Prospectus of Fresenius Medical Care Aktiengesellschaft ("Fresenius
Medical Care"), the Registrant, and Fresenius USA, Inc. ("Fresenius USA") dated
August 2, 1996 ("Proxy Statement-Prospectus"). The Reorganization was
accomplished pursuant to the Agreement and Plan of Reorganization dated as of
February 4, 1996, as amended (the "Reorganization Agreement"), among the
Registrant, Fresenius AG and Fresenius USA. Stockholders of the Registrant
approved the Reorganization on September 16, 1996. On September 27, 1996,
pursuant to the Distribution Agreement, dated February 4, 1996, among the
Registrant, W. R. Grace & Co. - Conn. ("Grace Chemicals") and Fresenius AG, the
Registrant distributed to its common stockholders 100% of the capital stock of
Grace Holding, Inc., a Delaware corporation and formerly a wholly owned
subsidiary of the Registrant, which holds all of the assets and liabilities
formerly held by Registrant, other than those of its wholly owned subsidiary,
National Medical Care, Inc. ("NMC") (the "Distribution"). Immediately following
the Distribution, (i) the Registrant was recapitalized so that each holder of
shares of Grace Common Stock received one share of Grace Class D Special
Dividend Preferred Stock ("Class D Preferred Stock") for each share of Grace
Common Stock held of record as of the close of business on September 27, 1996
and (ii) the Registrant's name was changed to Fresenius National Medical Care
Holdings, Inc. Thereafter, WRG Merger Sub Inc., a New York corporation and a
wholly owned subsidiary of Fresenius Medical Care AG ("Fresenius Medical Care"),
a German corporation, merged with and into the Registrant (the "FNMC Merger")
with the Registrant the surviving corporation. As a result of the
Reorganization, the Registrant became a subsidiary of Fresenius Medical Care.
All of the capital stock of Fresenius USA will shortly be contributed to the
Registrant by Fresenius Medical Care. Fresenius Medical Care now owns all of the
common stock of the Registrant, par value $1.00 per share (the "FNMC Common
Stock"). Fresenius Medical Care beneficially owns no shares of the outstanding
6% Preferred Stock, Class A Preferred Stock, Class B Preferred Stock and Class D
Preferred Stock of the Registrant.

         In the FNMC Merger, shareholders of the Registrant (other than
Fresenius AG and its respective subsidiaries) received 0.34969667 Ordinary
Shares of Fresenius Medical Care, evidenced by American Depositary Shares
represented by American Depositary Receipts, for each share of common stock of
the Registrant held by them. The nature and amount of consideration issued to
shareholders of the Registrant is described in the Proxy Statement-Prospectus
under the caption "THE REORGANIZATION -- Consideration to Shareholders." The
amount of such consideration was determined in the course of arm's length
negotiations between Fresenius AG and the Registrant as described in the Proxy
Statement-Prospectus under the caption "BACKGROUND AND REASONS -- Background of
the Reorganization; Reasons for the Recommendation of the Grace Board".

         Prior to the closing under the Reorganization Agreement, NMC entered
into the Credit Agreement dated as of September 27, 1996 by and among NMC,
certain subsidiaries and affiliates, the lenders named therein, Nationsbank
N.A., The Bank of Nova Scotia, The Chase Manhattan Bank and Dresdner Bank AG
(the "NMC Credit Agreement"). The Reorganization


                                        1
   3
Agreement required that NMC make a payment (the "Distribution Payment") to Grace
Chemicals prior to the Effective Date (as defined in the Reorganization
Agreement) in the amount of approximately $2.1 billion, subject to adjustment.
The source of funds for the Distribution Payment, the repayment of certain
indebtedness of Grace Chemicals and the working capital needs of NMC is the NMC
Credit Agreement. Accordingly, on September 27, 1996, NMC borrowed $2.5 billion
under the NMC Credit Agreement.

         The NMC Credit Agreement required that the Registrant guarantee
obligations thereunder. In addition, Grace Chemicals agreed to guarantee certain
obligations thereunder. Under the terms of the NMC Credit Agreement, Grace
Chemicals may be released from such guarantees if Fresenius Medical Care becomes
a guarantor thereunder, and Registrant understands that Fresenius Medical Care
intends to become a guarantor of the obligations under the NMC Credit Agreement,
upon the occurrence of certain specified conditions, but not sooner than
forty-six days after the Effective Date.

         In connection with Grace Chemicals' agreement to extend guarantees
under the NMC Credit Agreement, to provide a significant inducement for the
release of such guarantees as to $800 million on or prior to the 50th day
following the Effective Date, Fresenius Medical Care and Grace Chemicals entered
into a Letter Agreement dated September 27, 1996, generally providing that, if
such Grace Chemicals guarantees have not been released as to $800 million prior
to the close of business on the 50th day following the Effective Date, Fresenius
Medical Care will, at such time, make a $300 million payment to W. R. Grace
Foundation, Inc. (which contribution may not be used to satisfy any legal
obligation of Grace Chemicals). In addition, Fresenius Medical Care agreed that
(i) it would contribute the capital stock of Fresenius USA to Grace promptly
following the Effective Date and (ii) until the earlier to occur of (A) the
expiration of the 49-day period following the Effective Date and (B) such
earlier date upon which the Grace Chemicals guarantees have been released as to
$800 million, (a) it will not engage, or permit NMC to engage, in any settlement
discussions regarding certain governmental investigatory matters without Grace
Chemicals' participation and consent; (b) it will cause the respective
businesses of NMC and Fresenius USA to be conducted in the ordinary course,
without incurring additional debt (other than borrowings permitted under the NMC
Credit Agreement), without relinquishing or modifying contracts with affiliates
of Fresenius AG and without making cash distributions other than to a subsidiary
of Grace and (c) no new loan, letter of credit, or other financial accommodation
will be originated under the NMC Credit Agreement that would require the
confirmation contemplated in Section 4.9(a)(iii) thereof.

         In connection with the above, Fresenius Medical Care also agreed that,
during the 45-day period following the Effective Date, subject to certain
exceptions, it will not (i) make a capital contribution to the Registrant (or
its subsidiaries); (ii) provide any guarantee of any debt of the Registrant (or
its subsidiaries), (iii) take any other action that has the effect, directly or
indirectly, of subjecting the assets of Fresenius Medical Care (other than the
Registrant (or its subsidiaries)) to secure or otherwise support the debt of
NMC.



                                        2

         The Registrant knows of no arrangements, including any pledge by any
person of securities of the Registrant or any of its parents, the operation of
which may at a subsequent date result in a change in control of the Registrant.

ITEM 5. OTHER EVENTS.

         Following the FNMC Merger, the New York Stock Exchange, Inc. ("NYSE")
suspended trading, effective before the opening of business on September 30,
1996, in the FNMC Common Stock (NYSE:GRA) and terminated the listing of the FNMC
Common Stock. The Registrant will continue to file reports, proxy statements and
other information with the Commission under the Securities Exchange Act of 1934
with respect to the Class D Preferred Stock.
