4.    COMPENSATION AND BENEFITS.


a)    Base Salary. EMPLOYER shall pay EMPLOYEE for all services rendered a base
      salary of Two Hundred Sixty Thousand Dollars ($260,000) per year, (the
      "Base Salary"), payable in accordance with FMC's payroll procedures,
      subject to customary withholding and employment taxes. At the end of each
      year of employment hereunder, EMPLOYEE's performance for the prior year
      shall be reviewed and evaluated. If EMPLOYEE's performance is

b)    Incentive Compensation. During EMPLOYEE's employment with FMC, EMPLOYEE
      shall be entitled to participate in FMC's Management Bonus Plan and any
      other such incentive compensation plans as are now available or may become
      available to other similarly positioned senior executives of FMC. EMPLOYEE
      will be in the senior executive eligibility Level II, wherein the target
      level bonus is forty percent (40%) and the maximum bonus is eighty percent
      (80%) of base salary. Funding for the plan is based upon attainment of
      specific individual and company financial objectives. EMPLOYEE's
      entitlement to a bonus under the Management Bonus Plan will be governed by
      terms of that Plan.
   2
c)    Stock Plan. EMPLOYEE shall be eligible to participate in the current
      Fresenius Medical Care AG Stock Incentive Plan, and any future stock
      incentive plan (individually a "Stock Plan" and collectively, the "Stock
      Plans"), subject to IRS approval of such respective Stock Plans. In
      addition to the existing options to purchase Fresenius Medical Care AG
      Preference Shares previously granted to EMPLOYEE (the "Existing Options"),
      EMPLOYEE shall be eligible to receive additional option grants in amounts
      as and if approved by the Fresenius Medical Care AG Managing Board.

      the group employee benefits programs at the senior executive level as now
      established or which subsequently become available.

      accordance with FMC's policy, currently capped at Four Hundred Thousand
      Dollars ($400,000). EMPLOYEE will be provided with the opportunity to
      purchase supplemental life insurance of an additional Six Hundred Thousand
      Dollars ($600,000) beyond the current policy of coverage at his own

f)    Automobile. EMPLOYEE will be provided with a company car allowance of Five
      Hundred Dollars ($500) paid monthly and treated as ordinary income.

g)    Financial Planning/Tax Preparation. EMPLOYEE will be provided with an
      allowance of One Thousand Dollars ($1,000) to be paid based upon submitted

      assistance or income tax preparation. Reimbursement will be treated as
      ordinary income.


h)    Expenses. EMPLOYEE will be reimbursed for travel and other expenses
      related to the performance of his duties under the Agreement and in
      accordance with the EMPLOYER's policies.


i)    Vacation/PTO. EMPLOYEE shall be allowed to carry-over up to two hundred
      (200) hours from year-to-year without losing such time. EMPLOYEE shall
      also accrue PTO days at the maximum available to senior executives under
      the Executive Vacation Policy which currently provides for thirty (30)
      days of PTO per year.

5.    TERMINATION OF EMPLOYMENT. EMPLOYEE's employment hereunder may be
      terminated under the following circumstances:

a)    Death. EMPLOYEE's employment hereunder shall terminate upon his death.


b)    Total Disability. The EMPLOYER may terminate EMPLOYEE's employment
      hereunder upon EMPLOYEE becoming "Totally Disabled." For purposes of this
      Agreement, EMPLOYEE shall be "Totally Disabled" if EMPLOYEE is physically
      or mentally incapacitated so as to render EMPLOYEE incapable of performing
      EMPLOYEE's usual and customary duties under this Agreement. EMPLOYEE's
      receipt of Social Security disability benefits or disability benefits
      under a Company-sponsored long-term disability plan shall be deemed
      conclusive evidence of Total Disability for purpose of this Agreement;
      provided, however, that in the absence of EMPLOYEE's receipt of such
      Social Security or long-term disability benefits, the Company's Board of
      Directors may, in its reasonable discretion (but based upon medical
      evidence), determine that EMPLOYEE is Totally Disabled.

c)    Voluntary Termination. EMPLOYER or EMPLOYEE may terminate EMPLOYEE's
      employment hereunder at any time after providing written notice to the
      other party. The EMPLOYEE is required to give the EMPLOYER at least thirty
      (30) days written notice if he wishes to terminate his employment pursuant
      to this provision. EMPLOYEE is employed as a Senior Vice President of
      FMCNA with the P&L responsibility of Spectra Renal Management and the
      Information Services Group. Any reduction in this level of management
      responsibility or reduction of base salary can be determined by the
      EMPLOYEE to be a breach of this contract, and at his option, be
      terminated. If the EMPLOYEE elects to terminate this contract, the company
      would compensate the EMPLOYEE under Section 6.


                                       2
   3
d)    Termination by the EMPLOYER for Cause. The EMPLOYER may terminate
      EMPLOYEE's employment for Cause at any time after providing written notice
      to EMPLOYEE. For purposes of this Agreement, the term "Cause" shall mean,
      with respect to the EMPLOYEE, any of the following: (i) commission by
      EMPLOYEE of a felony or of any criminal act involving moral turpitude
      which results in an arrest or indictment; (ii) deliberate and continual
      refusal to satisfactorily perform employment duties reasonably requested
      by the EMPLOYER after 20 days' written notice by certified mail of such
      failure to perform, specifying that the failure constitutes cause (other
      than as a result of vacation, sickness, illness or injury); (iii) fraud or
      embezzlement determined in accordance with the EMPLOYER's normal, internal
      investigative procedures consistently applied in comparable circumstances
      to EMPLOYEES; (iv) gross misconduct or gross negligence in connection with
      the business of the EMPLOYER which has substantial effect on the EMPLOYER;
      (v) failure to obtain and maintain in good order any licenses required for
      EMPLOYEE to perform his duties under this Agreement; or (vi) a breach of
      any of the covenants set forth in Section 7 below. EMPLOYEE will be
      considered to have been terminated for "Cause" if the EMPLOYER determines
      that EMPLOYEE engaged in an act constituting "Cause," regardless of
      whether the individual terminates employment voluntarily or is terminated
      involuntarily, and regardless of whether the individual's termination
      initially was considered to have been for "Cause." The determination of
      "Cause" shall be made by the EMPLOYER in its sole discretion, and shall be
      final and binding on all parties.


e)    Termination by EMPLOYEE for Cause. This Agreement may be terminated by
      EMPLOYEE in the event of a breach by FMC of any of its obligations under
      this Agreement, provided EMPLOYEE gives FMC written notice specifying the
      manner in which he believes FMC has breached this Agreement and FMC has
      thirty (30) days from receipt of such notice to cure such breach, or in
      the case of other than a non-payment of money breach, if such breach
      cannot be cured within thirty (30) days, to commence a good faith effort
      to cure.


f)    Notice of Termination. Any termination by the EMPLOYER or the EMPLOYEE
      under this Agreement shall be communicated by notice of termination to the
      other party hereto. For purposes of this Agreement, a Notice of
      Termination shall mean a notice in writing which shall indicate the
      specific termination provision in this Agreement relied upon to terminate
      EMPLOYEE's employment and shall set forth in reasonable detail the facts
      and circumstances claimed to provide a basis for termination of EMPLOYEE's
      employment under the provision so indicated.


6.    COMPENSATION FOLLOWING TERMINATION OF EMPLOYMENT.

a)    Under all circumstances, upon termination the EMPLOYEE shall be entitled
      to receive:

            (i)   Any accrued but unpaid Base Salary for services rendered to
                  the date of termination; and

            (ii)  Any benefits to which EMPLOYEE may be entitled upon
                  termination pursuant to the plans, policies and arrangements
                  referred to in Section 4 hereof shall be determined and paid
                  in accordance with the terms of such plans, policies and
                  arrangements. ** EMPLOYEE shall have three (3) years from any
                  such termination to exercise his Vested Stock Options. Should
                  he fail to exercise these options within this period, they
                  will be forfeited at the end of that period.


b)    In the event that EMPLOYEE's employment hereunder is voluntarily
      terminated by the EMPLOYER in accordance with Section 5(c), or in the
      event that EMPLOYEE's employment hereunder is terminated by the EMPLOYEE
      in accordance with Section 5(e), the EMPLOYEE shall also be entitled to
      receive:


            (i)   A payment equal to twenty-four (24) months Base Salary, at the
                  rate in effect on the date of termination of employment, such
                  amount to be paid in a lump sum as soon as is practicable
                  thereafter; and


            (ii)  A pro-rated portion of the EMPLOYEE's annual bonus based upon
                  termination of work date.


                                       3
   4
c)    Any stock options or other awards will continue to vest in accordance with
      the terms of the award and the plan pursuant to which it was made. If the
      terms of any award and governing plan are silent with respect to
      termination of employment, such award will lapse immediately upon such
      termination.

7.    NON-DISCLOSURE/NON COMPETITION AGREEMENT. EMPLOYEE acknowledges that
      during the term of employment with EMPLOYER, he will have access to and
      become acquainted with Confidential Information of the EMPLOYER.
      Confidential Information means all information related to the present or
      planned business of FMC that has not been released publicly by authorized
      representatives of FMC, and shall include but not be limited to, trade
      secrets and know-how, inventions, marketing and sales programs, employee,
      customer, patient and supplier information, information from patient
      medical records, financial data, pricing information, regulatory approval
      and reimbursement strategies, data, operations and clinical manuals.

      EMPLOYEE agrees not to use or disclose, directly or indirectly, any
      Confidential Information of FMC at any time and in any manner, except as
      required in the course of his employment with FMC or with the express
      written authority of FMC.

      EMPLOYEE understands that his non-disclosure obligations will continue
      following his termination of employment.

      EMPLOYEE agrees that during the term of his employment, and for a period
      of one (1) year immediately after, he leaves the employment of FMC for any
      reason or the end of the period during which EMPLOYEE continues to receive
      salary continuation after leaving the employment of FMC, whichever is
      greater, EMPLOYEE will not directly or indirectly for his own benefit or
      the benefit of others:

      a)    render services for a competing organization in connection with
            competing products as an employee, officer, agent, broker,
            consultant, partner, stockholder (except that EMPLOYEE may own three
            percent (3%) or less of the equity securities of any publicly-traded
            company);

      b)    hire or seek to persuade any employee of FMC to discontinue
            employment or to become employed in any competing organization or
            seek to persuade any independent contractor or supplier to
            discontinue its relationship with FMC; and

      c)    solicit, direct, take away or attempt to take away any business or
            customers of FMC.


      Nothing in this Agreement would preclude EMPLOYEE from working for a
      competitor of FMC's subsequent to termination of EMPLOYEE's employment
      provided EMPLOYEE will not be engaged, directly or indirectly, in any
      business in which FMC is actively engaged at the time of EMPLOYEE's
      termination or in any new business which FMC is in the process of setting
      up in which EMPLOYEE had direct involvement while employed by FMC.
      EMPLOYEE also agrees to inform FMC of any such employment with a
      competitor before beginning such employment.


8.    ENFORCEMENT OF COVENANTS.


a)    Termination of Employment and Forfeiture of Compensation. EMPLOYEE agrees
      that in the event that the EMPLOYER determines that EMPLOYEE has breached
      any of the covenants set forth in Section 7 hereof during EMPLOYEE's
      employment, the EMPLOYER shall have the right to terminate EMPLOYEE's
      employment for "Cause." For purposes of this Agreement, the term "Cause"
      shall mean, with respect to the EMPLOYEE, any of the following: (i)
      commission by EMPLOYEE of a felony or of any criminal act involving moral
      turpitude which results in an arrest or indictment; (ii) deliberate and
      continual refusal to satisfactorily perform employment duties reasonably
      requested by the EMPLOYER after 20 days' written notice by certified mail
      of such failure to perform, specifying that the failure constitutes cause
      (other than as a result of vacation, sickness, illness or injury); (iii)
      fraud or embezzlement determined in accordance with the EMPLOYER's normal,
      internal investigative procedures consistently applied in comparable
      circumstances to EMPLOYEES; (iv) gross misconduct or gross negligence in
      connection with the business of the EMPLOYER

                                       4
   5
      which has substantial effect on the EMPLOYER; (v) failure to obtain and
      maintain in good order any licenses required for EMPLOYEE to perform his
      duties under this Agreement; or (vi) a breach of any of the covenants set
      forth in Section 7 above. EMPLOYEE will be considered to have been
      terminated for "Cause" if the EMPLOYER determines that EMPLOYEE engaged in
      an act constituting "Cause," regardless of whether the individual
      terminates employment voluntarily or is terminated involuntarily, and
      regardless of whether the individual's termination initially was
      considered to have been for "Cause." The determination of "Cause" shall be
      made by the EMPLOYER in its sole discretion, and shall be final and
      binding on all parties.


      In addition, EMPLOYEE agrees that if the EMPLOYER determines that EMPLOYEE
      has breached any of the covenants set forth in Section 7 at any time, the
      EMPLOYER shall have the right, notwithstanding anything herein to the
      contrary, to discontinue any or all amounts otherwise payable to EMPLOYEE
      hereunder. Such termination of employment or discontinuance of payments
      shall be in addition to and shall not limit any and all other rights and
      remedies that the EMPLOYER may have against EMPLOYEE.

b)    Right to Injunction. EMPLOYEE acknowledges that a breach of the covenants
      set forth in Section 7 hereof will cause irreparable damage to the
      EMPLOYER with respect to which the EMPLOYER's remedy at law for damages
      will be inadequate. Therefore, in the event of breach or anticipatory
      breach of the covenants set forth in this section by EMPLOYEE, EMPLOYEE
      and the EMPLOYER agree that the EMPLOYER shall be entitled to the
      following particular forms of relief, in addition to remedies otherwise
      available to it at law or equity: (i) injunctions, both preliminary and
      permanent, enjoining or retraining such breach or anticipatory breach and
      EMPLOYEE hereby consents to the issuance thereof forthwith and without
      bond by any court of competent jurisdiction; and (ii) recovery of all
      reasonable sums expended and costs, including reasonable attorney's fees,
      incurred by the EMPLOYER to enforce the covenants set forth in this
      section.

c)    Separability of Covenants. The covenants contained in Section 7 hereof
      constitute a series of separate covenants, one for each applicable State
      in the United States and the District of Columbia, and one for each
      applicable foreign country. If in any judicial proceeding, a court shall
      hold that any of the covenants set forth in Section 7 exceed the time,
      geographic, or occupational limitations permitted by applicable laws,
      EMPLOYEE and the EMPLOYER agree that such provisions shall and are hereby
      reformed to the maximum time, geographic, or occupational limitations
      permitted by such laws. Further, in the event a court shall hold
      unenforceable any of the separate covenants deemed included herein, then
      such unenforceable covenant or covenants shall be deemed eliminated from
      the provisions of this Agreement for the purpose of such proceeding to the
      extent necessary to permit the remaining separate covenants to be enforced
      in such proceeding. EMPLOYEE and the EMPLOYER further agree that the
      covenants in Section 7 shall each be construed as a separate agreement
      independent of any other provisions of this Agreement, and the existence
      of any claim or cause of action by Employee against the Company whether
      predicated on this Agreement or otherwise, shall not constitute a defense
      to the enforcement by the Company of any of the covenants in Section 7.


9.    FMC DOCUMENTS AND EQUIPMENT. All documents and equipment relating to the
      business of FMC, whether prepared by EMPLOYEE or otherwise coming into
      EMPLOYEE's possession, are the exclusive property of FMC, and must not be
      removed from the premises of FMC except as required in the course of
      employment. Any such documents and equipment must be returned to FMC when
      EMPLOYEE leaves the employment of FMC.


10.   WITHHOLDING OF TAXES. The EMPLOYER may withhold from any compensation and
      benefits payable under this Agreement all applicable federal, state,
      local, or other taxes.

11.   ENTIRE AGREEMENT AND AMENDMENTS. This Agreement shall constitute the
      entire agreement between the parties and supersedes all existing
      agreements between them, whether oral or written, with respect to the
      subject matter hereof. Any waiver, alteration, or modification of any of
      the provisions of this Agreement, or cancellation or replacement of this
      Agreement shall be accomplished in writing and signed by the respective
      parties.

13.   GOVERNING LAW. This Agreement shall be construed in accordance with, and
      the rights of the parties shall be governed by, the laws of the
      Commonwealth of Massachusetts.

14.   SEPARABILITY. If any term or provision of this Agreement is declared
      illegal or unenforceable by any court of competent jurisdiction and cannot
      be modified to be enforceable, such term or provision shall immediately
      become null and void, leaving the remainder of this Agreement in full
      force and effect.
