(1)     The capital stock of the Company amounts to Euro 239,994,112.00 and is
        divided into seventy million (70,000,000) bearer shares of the common
        stock and 23,747,700 non-voting bearer shares of the preferred stock.


        In case of issuance of non-voting bearer shares of the preferred stock,
        particulars thereof are set forth in Article 19.


        No consent of the preferred shareholders shall be required for the
        issuance of non-voting preferred shares which, for the distribution of
        the profits or the corporate assets, will be equal to or be preferred to
        the non-voting preferred shares existing from time to time.

                                     - 3 -


(2)     The capital stock in the amount of DM 100,000 available at the
        transformation was raised through change of the legal form of Fresenius
        Medical Care GmbH with registered office in Hof an der Saale, the
        previous legal entity owning the assets and liabilities of the Company.


(3)     The Managing Board shall be authorized, with the approval of the
        Supervisory Board, to increase the capital stock of the company during
        the period up to 29 May 2005 by a maximum amount of EUR 30,720,000.00
        through the non-recurrent or recurrent issue of new non-voting bearer
        preference shares (Authorized Capital I). The number of shares has to
        increase in proportion to the capital stock. The increases in capital
        have to take place against cash contributions. The Managing Board shall
        also be entitled, in each case subject to the approval of the
        Supervisory Board, to decide on an exclusion of the subscription right
        of the shareholders. However, such an exclusion of the subscription
        right shall only be permissible for fractional amounts.


(4)     The Managing Board shall be authorized, with the approval of the
        Supervisory Board, to increase the capital stock of the Corporation
        during the period up to 22 May 2006 by a maximum amount of Euro
        20,480,000.00 through the non-recurrent or recurrent issue of new
        non-voting bearer preference shares (Authorized Capital II). The number
        of shares has to increase in proportion to the capital stock. The
        increases in capital may take place against cash contributions or
        contributions in kind. The Managing Board shall also be entitled, in
        each case subject to the approval of the Supervisory Board, to decide on
        an exclusion of the subscription right of the shareholders. However,
        such an exclusion of the subscription right shall only be permissible
        if, in case of a capital increase against cash contributions, the issue
        price is not significantly lower than the stock exchange price, and/or,
        in case of a capital increase against contributions in kind, the purpose
        of such increase is to acquire an enterprise or an interest in an
        enterprise.


(5)     The capital stock of the Corporation is contingently increased by a
        maximum of Euro 6,144,000, divided into a maximum of 2.4 million par
        value shares, through the issue of new, non-voting bearer preference
        shares. The conditional capital increase will be made only to the extent
        that the holders of the convertible bonds issued by Fresenius Medical
        Care Aktiengesellschaft on the basis of the authority of the
        shareholders' meeting of September 24, 1996 will exercise their rights
        to convert the bonds into new shares. The new shares will participate in
        the profits as from the beginning of the business year in which they are
        created as a result of exercise of conversion rights.

(6)     The capital stock of the Corporation is contingently increased by a
        maximum of Euro 3,072,000, divided into a maximum of 1.2 million par
        value shares, through the issue of new, non-voting bearer preference
        shares. The conditional capital increase will be made only to the extent
        that subscription rights are granted pursuant to the stock option
        program in accordance with the resolution passed at the shareholders'
        meeting of June 10, 1998, and of the resolution of the shareholders'
        meeting of May 30, 2000, and the owners of the subscription rights
        exercise their subscription rights. The new non-voting bearer shares of
        the preferred stock will participate in the profits as from the
        beginning of the business year in which issuance occurs.


(7)     The capital stock of the Corporation is contingently increased by a
        maximum of Euro 10,240,000, divided into a maximum of 4 million
        non-voting bearer preference shares, through the issue of new non-voting
        bearer preference shares in order to secure the convertible bonds
        adopted by resolution in the general meeting of 23 May 2001. The
        contingent capital increase shall only take place insofar as convertible
        bonds for par value shares are issued according to the international
        participation scheme for employees pursuant to the resolution of the
        general meeting of 23 May 2001 and insofar as the holders of such
        convertible bonds exercise their conversion right. The new non-voting
        bearer preference shares shall participate in profits as of the start of
        the fiscal year in which they are issued.


(8)     In case of a capital increase, the profit participation may be
        determined in derogation of Section 60, para. 2 AktG [German Corporation
        Law].


                                    ARTICLE 5
                                     SHARES


(1)     The shares will be no par value bearer shares.


(2)     The Company shall be entitled to issue share certificates made out to
        bearer each evidencing a plurality of shares (several-share
        certificates).


(3)     The form of the share certificates and of the dividend coupons and
        renewal coupons shall be determined by the management board with the
        consent of the supervisory board.


(4)     The Company shall take the necessary measures to achieve that its shares
        will, as far as possible, be admitted for official quotation on the
        stock exchange in


   5
                                     - 5 -


        Frankfurt am Main and in suitable form - e.g. as "American Depositary
        Shares" - on the New York Stock Exchange and that such admissions will
        be maintained. With the consent of the supervisory board which must
        decide unanimously on such consent, the management board may determine
        deviations from this provision.

(1)     The supervisory board consists of six (6) members.


        All six (6) members shall be elected by the shareholders' meeting
        according to the provisions of the German Aktiengesetz.


(2)     Unless expressly otherwise resolved by the shareholders' meeting, the
        supervisory board members shall be appointed to hold office until the
        end of the ordinary shareholders' meeting which resolves on the
        exoneration for the fourth business year after commencement of the term
        of office. The year in which the term of office commences shall not be
        considered for this calculation. Reelection of supervisory board members
        shall be permissible.


(3)     If a member elected by the shareholders' meeting withdraws from the
        supervisory board before expiration of his term of office, a new member
        is to be elected in the next shareholders' meeting to replace the
        withdrawing member. The newly elected member shall hold office for the
        remaining term of office of the withdrawing member.


(4)     The shareholders' meeting may, for the supervisory board members to be
        elected by it, appoint substitute members who will become members of the
        supervisory board on the basis of a specific order to be determined upon
        election if and when supervisory board members withdraw before
        expiration of their term of office. Their position as substitute members
        shall revive if and when the shareholders' meeting elects a new member
        instead of the withdrawing supervisory board member replaced by such
        substitute member. The term of office of the substitute member shall end
        upon completion of the shareholders' meeting in which an election
        according to Article 8 (3) is made.


(5)     Each member of the supervisory board may resign from office by giving
        one month's written notice to the chairman of the supervisory board even
        without good cause. Notice of resignation from office by the chairman of
        the supervisory board shall be given to his deputy.

                      CONSTITUTION OF THE SUPERVISORY BOARD


(1)     Following the shareholders' meeting in which the supervisory board has
        been newly elected, the supervisory board shall hold a meeting without
        special notice of meeting and, where necessary, shall elect in such
        meeting from among its members a chairman and a deputy chairman for the
        whole term of office of the elected persons as supervisory board
        members.


(2)     If the chairman or his deputy resigns his office before expiration of
        his term of office, the supervisory board shall immediately hold a new
        election to replace the resigning chairman/deputy.

(1)     The meetings of the supervisory board shall be called by the chairman by
        written notice subject to a notice period of fourteen (14) days. The
        individual items on the agenda must be stated in the notice of meeting.
        In urgent cases, this period may be shortened or the meeting may be
        called by telegram, telex, telefax or telephone.


(2)     The resolutions of the supervisory board shall be adopted in meetings.
        The resolutions may be passed by written document, by telegram, telex,
        telefax or telephone if the chairman of the supervisory board or, in
        case of the chairman being prevented, his deputy so directs and all
        members of the supervisory board approve of such procedure expressly or
        by voting.


(3)     The supervisory board shall constitute a quorum if half the members
        making up the entire board take part in the adoption of the resolution.
        Those items on the agenda which have not been announced properly within
        the meaning of para. (1) above may be voted on only if none of the
        present members objects thereto.


(4)     If members of the supervisory board are prevented from attending the
        meeting, they may have another member of the supervisory board submit
        their written votes. Such delivery of the written vote shall be deemed
        to be participation in the adoption of the resolution.


(5)     Resolutions of the supervisory board shall require the majority of the
        votes cast unless otherwise provided by law or the Articles of
        Association. In case of a tie, a

        new vote shall be taken on the same issue at the request of the chairman
        of the supervisory board or of another member of the supervisory board.
        In the event that such new vote leads again to a tie, the chairman of
        the supervisory board shall have two (2) votes (to the legally
        permissible extent, this shall apply also to committees of the
        supervisory board of which he is a member). Article 10 (4) shall be
        applicable to the casting of the second vote. The deputy of the chairman
        of the supervisory board shall not be entitled to such second vote.


(6)     Minutes of the meetings of the supervisory board shall be prepared and
        translated into the English language. The minutes shall be signed by the
        chairman of the meeting. Any minutes to be prepared with respect to
        resolutions adopted by written document, by telegram, telex, telefax or
        telephone shall be signed by the chairman of the supervisory board.

        inspect and audit can also be claimed by any individual supervisory
        board member; if the management board objects to this right, it may be
        enforced only if and when the request is supported by another
        supervisory board member. The supervisory board member must direct his
        request to the chairman of the supervisory board who shall pass the
        request on to the management board or, if a chairman of the management
        board has been appointed (Art. 7 (2) sentence 2), to such chairman.


(3)     The management board shall regularly report to the supervisory board. In
        addition, the supervisory board may request the submission of a report
        if and when there is reasonable cause therefor including where such
        cause relates to a business event at an affiliated company which has
        become known to the management board and which may substantially
        influence the situation of the Company. Article 11 (2), sentences 2 and
        3 shall apply mutatis mutandis.


(4)     The supervisory board shall issue rules of procedure for the management
        board in accordance with Article 7 (4).

                                     - 10 -


(5)     The supervisory board shall be entitled, without resolution of the
        shareholders' meeting, to make amendments to the Articles of Association
        which concern only the wording. This shall also apply to the cases
        referred to in Article 4 (3).


                                   ARTICLE 12
                   RULES OF PROCEDURE OF THE SUPERVISORY BOARD


The supervisory board shall, within the framework of the imperative legal
provisions and the Articles of Association, establish rules of procedure for
