NOTE 4.  SPECIAL CHARGE FOR SETTLEMENT OF INVESTIGATION AND RELATED COSTS

        Since 1995, NMC and certain subsidiaries had been the subject of an
investigation (the "OIG Investigation") by the Office of Inspector General
("OIG") of the United States Department of Health and Human Services, the United
States Attorney for the District of Massachusetts (the "U.S. Attorney's Office")
and other authorities concerning possible violations of federal laws, including
the anti-kickback statute and the False Claims Act.

        On January 18, 2000, the Company, NMC and certain affiliated companies
executed definitive agreements (the "Settlement Agreements") with the United
States Government (the "Government") to settle (i) the matters covered in the
OIG Investigation and (ii) NMC's claims with respect to approximately $153.5
million of outstanding Medicare receivables for nutrition therapy rendered on or
before December 31, 1999 (collectively, the "Settlement"). The Settlement was
approved by the United States District Court for the District of Massachusetts
on February 2, 2000.

        In anticipation of the Settlement, the Company recorded a special
pre-tax charge against its consolidated earnings in 1999 totaling $601 million
($419 million after tax). This special pre-tax charge included (i) a charge of
$486.3 million for settlement payment obligations to the Government, (ii) a
$94.3 million write-off of the remaining receivables described above, and (iii)
a reserve for other related costs of $20.4 million. The settlement payment
obligations to the Government and the amounts due to the Company for the
outstanding Medicare receivables have been classified in the balance sheet at
their expected settlement dates.

        Under the definitive agreements with the Government, the Company entered
into a note payable for the settlement payment obligations to the Government.
Interest on installment payments to the Government will accrue at 6.3% on $51.2
million of the obligation and at 7.5% annually on the balance, until paid in
full.

        In February 2000, the Company made initial payments to the Government
totaling $286.4 million. The remaining obligations will be paid in six quarterly
installments beginning April 2000 and ending July 2001. The first four quarterly
installments will be made in the amount of $35.4 million including interest at
7.5%. The remaining two installments of $27.8 million including interest at 6.3%
will be made in April and July 2001, respectively.

        In addition, the Company will receive approximately $59.2 million from
the Government related to the Company's claims for outstanding Medicare
receivables. In March 2000, the Company received an initial payment from the
Government of $38.4 million. The remaining balance will be received by the
Company in four quarterly payments beginning in May 2000 and ending February
2001. The quarterly receipts from the Government will be for principal of $5.2
million plus interest at 7.5%.

NOTE 5. COMMITMENTS AND CONTINGENCIES

LEGAL PROCEEDINGS

        DISTRICT OF MASSACHUSETTS

        With one exception, each of the qui tam or "whistleblower" actions which
served as the basis for the recently settled federal government investigation
were dismissed as a result of the Settlement. The exception is a portion of a
qui tam proceeding filed in the United States District Court for the Middle
District of Tennessee on December 15, 1994. That action was transferred to the
United States District Court for the District of Massachusetts in 1995, and
disclosed to the Company in September 1999. The portion of this qui tam action
that was not dismissed as a result of the settlement alleges, among other
things, that the Company violated the Medicare and Medicaid Anti-kickback
Statute by providing discounted hemodialysis products to induce the purchase of
laboratory services. In the Settlement Agreements, the U. S. government has
declined to continue to pursue further the investigation or prosecution of these
allegations. The government and the current and former employees who filed this
qui tam action, called "relators," offered to dismiss this portion of this qui
tam action in connection with the settlement. However, this offer required that
the Company grant a full release of all of the Company's claims against the
relators, and the Company was unwilling to do so. While there can be no
assurance, the Company believes that the resolution of these remaining
allegations will not have a material adverse impact on the Company's business,
financial condition or results of operations.

        COMMERCIAL INSURER LITIGATION

        In 1997, the Company, NMC, and certain named NMC subsidiaries, were
served with civil complaint filed by Aetna Life Insurance Company in the U.S.
District Court for the Southern District of New York. Based in large part on
information contained in prior reports filed by the Company with the Securities
and Exchange Commission, the lawsuit alleges inappropriate billing practices for
nutritional therapy, diagnostic and clinical laboratory tests and
misrepresentations. In April 1999, Aetna amended its complaint to include its
affiliate, Aetna U.S. Healthcare, Inc., as an additional plaintiff, and to make
certain other limited changes in its pleading. The amended complaint seeks
unspecified damages and costs. In February 2000, the Company was served with a
similar complaint filed by Connecticut General Life Insurance Company, Equitable

Inc. and Guardian Life Insurance Company of America, Inc. (Connecticut General
Life Insurance Company et al v. National Medical Care et al, 00-Civ-0932)
seeking unspecified damages and costs. However, the Company, NMC and its
subsidiaries believe that there are substantial defenses to the claims asserted,
and intend to vigorously defend both lawsuits. Other private payors have
contacted the Company and may assert that NMC received excess payment and,
similarly, may join either lawsuit or file their own lawsuit seeking
reimbursement and other damages.

        In May 1999, the Company filed counterclaims against Aetna Life
Insurance Company and Aetna U.S. Healthcare, Inc. based on inappropriate claim
denials and delays in claim payments. The Company is investigating similar
counterclaims against other private payors that have filed a complaint or
contacted them. An adverse result of these litigations could have a material
adverse effect on the Company's business, financial position and result of
operations.

        Although the ultimate outcome on the Company of these proceedings cannot
be predicted at this time, an adverse result could have a material adverse
effect on the Company's business, financial condition and result of operations.

        OBRA 93

        The Omnibus Budget Reconciliation Act of 1993 affected the payment of
benefits under Medicare and employer health plans for dual-eligible ESRD
patients. In July 1994, the Health Care Financing Administration issued an
instruction to Medicare claims processors to the effect that Medicare benefits
for the patients affected by that act would be subject to a new 18-month
"coordination of benefits" period. This instruction had a positive impact on
NMC's dialysis revenues because, during the 18-month coordination of benefits
period, patients' employer health plans were responsible for payment, which was
generally at rates higher than those provided under Medicare.

        In April 1995, the Health Care Financing Administration issued a new
instruction, reversing its original instruction in a manner that would
substantially diminish the positive effect of the original instruction on NMC's
dialysis business. The Health Care Financing Administration further proposed
that its new instruction be effective retroactive to August 1993, the effective
date of the Omnibus Budget Reconciliation Act of 1993.

        NMC ceased to recognize the incremental revenue realized under the
original instruction as of July 1, 1995, but it continued to bill employer
health plans as primary payors for patients affected by the Omnibus Budget
Reconciliation Act of 1993 through December 31, 1995. As of January 1, 1996, NMC
commenced billing Medicare as primary payor for dual eligible ESRD patients
affected by the act, and then began to re-bill in compliance with the revised
policy for services rendered between April 24 and December 31, 1995.

        On May 5, 1995, NMC filed a complaint in the U.S. District Court for the
District of Columbia (National Medical Care, Inc. and Bio-Medical Applications
of Colorado, Inc. d/b/a Northern Colorado Kidney Center v. Shalala, C.A.
No.95-0860 (WBB) seeking to preclude the Health Care Financing Administration
from retroactively enforcing its April 24, 1995 implementation of the Omnibus
Budget Reconciliation Act of 1993 provision relating to the coordination of
benefits for dual eligible ESRD patients. On May 9, 1995, NMC moved for a
preliminary injunction to preclude the Health Care Financing Administration from
enforcing its new policy retroactively, that is, to billing for services
provided between August 10, 1993 and April 23, 1995. On June 6, 1995, the court
granted NMC's request for a preliminary injunction and in December of 1996, NMC
moved for partial summary judgment seeking a declaration from the Court that the
Health Care Financing Administration's retroactive application of the April 1995
rule was legally invalid. The Health Care Financing Administration cross-moved
for summary judgement on the grounds that April 1995 rule was validly applied
prospectively. In January 1998, the court granted NMC's motion for partial
summary judgment and entered a declaratory judgement in favor of NMC, holding
the Health Care Financing Administration's retroactive application of the April
1995


                                       12
<PAGE>   13



rule legally invalid. Based on its finding, the Court also permanently enjoined
the Health Care Financing Administration from enforcing and applying the April
1995 rule retroactively against NMC. The Court took no action on the Health Care
Financing Administration's motion for summary judgement pending completion of
the outstanding discovery. On October 5, 1998, NMC filed its own motion for
summary judgement requesting that the Court declare the Health Care Financing
Administration's prospective application of the April 1995 rule invalid and
permanently enjoin Health Care Financing Administration from prospectively
enforcing and applying the April 1995 rule. The Court has not yet ruled on the
parties' motions. The Health Care Financing Administration elected not to appeal
the Court's June 1995 and January 1998 orders. The Health Care Financing
Administration may, however, appeal all rulings at the conclusion of the
litigation. If the Health Care Financing Administration should successfully
appeal so that the revised interpretation would be applied retroactively, NMC
may be required to refund the payment received from employer health plans for
services provided after August 10, 1993 under the Health Care Financing
Administration's original implementation, and to re-bill Medicare for the same
services, which would result in a loss to NMC of approximately $120 million
attributable to all periods prior to December 31, 1995. Also, in this event, the
Company's business, financial condition and results of operations would be
materially adversely affected.

        STATE OF FLORIDA

        In October 1999, NMC received an Antitrust Civil Investigative Demand
("CID") from the Attorney General of the State of Florida ("Florida AG"). The
CID was issued by the Florida AG in the course of an investigation to determine
whether there is, has been, or may be a violation of federal and Florida laws
resulting from the possible monopolization of, or the entering into agreement in
restraint of, trade relating to the provision of dialysis products and services
in Florida.

        The Company is cooperating with the Florida AG's investigation by
providing documents and other information to them. The impact of this
investigation on the business and financial condition, if any, cannot be
determined at this time.

         OTHER LITIGATION AND POTENTIAL EXPOSURES

         The Company, like other health care providers, conducts its operations
under intense government regulation and scrutiny. The Company must comply with
regulations which relate to or govern the safety and efficacy of medical
products and supplies, the operation of manufacturing facilities, laboratories
and dialysis clinics, and environmental and occupational health and safety. The
Company must also comply with the U.S. anti-kickback statute, the False Claims
Act, the Stark Law, and other federal and state fraud and abuse laws. Applicable
laws or regulations may be amended, or enforcement agencies or courts may make
interpretations that differ from the Company's or the manner in which the
Company conduct its business. In the U.S., enforcement has become a high
priority for the federal government and some states, due in part to budgetary
constraints on the government reimbursement programs and the high level of
visibility accorded to government efforts to deal with alleged fraud and abuse.
In addition, the provisions of the False Claims Act authorizing payment of a
portion of any recovery to the party bringing the suit encourage private
plaintiffs commence "whistle blower" actions. By virtue of this regulatory
environment, as well as our corporate integrity agreement with the government,
the Company expects that its business activities and practices will continue to
be subject to expensive review by regulatory authorities, and the Company cannot
exclude the possibility of additional inquiries, claims and litigation relating
to its compliance with applicable laws and regulations. The Company may not
always be aware that an inquiry or action has begun, particularly in the case of
"whistle blower" actions, which are initially filed under court seal.

         The Company operates a large number and wide variety of facilities
throughout the U.S. In such a decentralized system, it is often difficult to
maintain the desired level of oversight and control over the thousands of
individuals employed by many affiliate companies. The Company relies upon its
management structure, regulatory and legal resources, and the effective
operation of its compliance program to direct, manage and monitor the activities
of these employees. However, on occasion, the Company has identified instances
where employees, deliberately or inadvertently, have submitted inadequate or
false billings. The illegal actions of such persons may subject the Company and
its subsidiaries to liability under the False Claims Act, among other laws, and
the Company cannot predict whether law enforcement authorities may use such
information to initiate further investigations of the business practices
disclosed or any of its other business activities.

         Physicians, hospitals and other participants in the health care
industry are also subject to a large number of lawsuits alleging professional
negligence, malpractice, product liability, worker's compensation or related
claims, many of which involve large claims and significant defense costs. The
Company has been subject to these suits due to the nature of its business and
the Company expects that those types of lawsuits may continue. Although the
Company maintains insurance at a level which it believes to be prudent, the


                                       13
<PAGE>   14


Company cannot assure that the coverage limits will be adequate or that
insurance will cover all asserted claims. A successful claim against the Company
or any of its subsidiaries in excess of insurance coverage could have a material
adverse effect upon the Company and the results of its operations. Any claims,
regardless of their merit or eventual outcome, also may have a material adverse
effect on the Company's reputation and business.

         CONTINGENT NON-NMC LIABILITIES OF W.R. GRACE & CO. (NOW KNOWN AS
FRESENIUS MEDICAL CARE HOLDINGS, INC.)

         The Company was formed as a result of a series of transactions pursuant
to the Agreement and Plan of Reorganization (the "Merger") dated as of February
4, 1996 by and between W.R. Grace & Co.-Conn. ("Grace Chemicals"). In connection
with the Merger, Grace Chemicals agreed to indemnify the Company and NMC against
all liabilities of the Company and its successors, whether relating to events
occurring before or after the Merger, other than liabilities arising from or
relating to NMC operations. The Company remains contingently liable for certain
liabilities with respect to pre-Merger matters that are not related to NMC
operations. The Company believes that in view of the nature of the non-NMC
liabilities and Grace Chemicals' current financial position, the risk of
significant loss from non-NMC liabilities is remote.

         Were events to violate the tax-free nature of the Merger, the resulting
tax liability would be the obligation of the Company. Subject to representations
by Grace Chemicals, the Company and Fresenius AG, Grace Chemicals has agreed to
indemnify the Company for such a tax liability. If the Company was not able to
collect on the indemnity, the tax liability would have a material adverse effect
on the Company's business, the financial condition of the Company and the
results of operations.

NOTE 6. INDUSTRY SEGMENTS INFORMATION

     The Company's reportable segments are Dialysis Services and Dialysis
Products. For purposes of segment reporting, the Dialysis Services Division and
Spectra Renal Management are combined and reported as Dialysis Services. These
divisions are aggregated because of their similar economic classifications.
These include the fact that they are both health care service providers whose
services are provided to a common patient population, and both receive a
significant portion of their net revenue from Medicare and other government and
non-government third party payors. The Dialysis Products segment reflects the
activity of the Dialysis Products Division only.

The table below provides information for the three months ended March 31, 2000
and 1999 pertaining to the Company's two industry segments.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         The following is a discussion of the financial condition and results of
operations of the Company. The discussion should be read in conjunction with the
financial statements included elsewhere in this document.

         This section contains certain forward-looking statements that are
subject to various risks and uncertainties. Such statements include, without
limitation, discussions concerning the outlook of the Company, government
reimbursement, future plans and management's expectations regarding future
performance. Actual results could differ materially from those contained in
these forward-looking statements due to certain factors including, without
limitation, changes in business, economic and competitive conditions, regulatory
reforms, foreign exchange rate fluctuations, uncertainties in litigation or
investigative proceedings, the realization of anticipated tax deductions, and
the availability of financing. These and other risks and uncertainties, which
are more fully described elsewhere in this Item 2 and in the Company's reports
filed from time to time with the Commission, could cause the Company's results
to differ materially from the results that have been or may be projected by or
on behalf of the Company.

RESULTS OF OPERATIONS

         The following table summarizes certain operating results of the Company
by principal business unit for the periods indicated. Intercompany eliminations
primarily reflect sales of medical supplies by Dialysis Products to Dialysis

THREE MONTHS ENDED MARCH 31, 2000 COMPARED TO THREE MONTHS ENDED MARCH 31, 1999

         Net revenues for the first three months of 2000 increased by 11% ($73
million) over the comparable period in 1999. Net earnings for the first three
months of 2000 increased by 31% ($5 million) over the comparable period in 1999
as a result of increased operating earnings and decreased general corporate
expenses, partially offset by higher interest expenses.

         DIALYSIS SERVICES

         Dialysis Services net revenues for the first three months of 2000
increased by 13% ($73 million) over the comparable period in 1999, primarily as
a result of an 8% increase in the number of treatments provided, the impact of
increased Medicare reimbursement rates, improved anemia management (higher EPO
utilization), consolidation of previously managed locations, and increased
laboratory testing revenues. The treatment increase was a result of base
business growth and the impact of 1999 and 2000 acquisitions. The laboratory
testing revenues increased as a result of higher patient volume.

         Dialysis Services operating earnings for the first three months of 2000
increased by 13% ($11 million) over the comparable period of 1999 primarily due
to the increase in treatment volume, improved anemia management (higher EPO
utilization), increased earnings from laboratory testing, and a decrease in the
provision for doubtful accounts. The reduction in the provision for doubtful
accounts as compared to 1999 is due to an increase in estimated bad debt
recovery from cost reports.

         DIALYSIS PRODUCTS

         Dialysis Products net revenues for the first three months of 2000
increased by 4% ($6 million) over the comparable period of 1999. This is due to
increased sales of machines ($5 million), concentrates ($2 million), bloodlines
($1 million), and other products ($2 million), partially offset by decreased
sales of peritoneal products ($3 million) and dialyzers ($1 million). Revenue
growth over the comparable period was primarily volume driven.

         Dialysis Products operating earnings for the first three months of 2000
decreased by 10% ($3 million) over the comparable period of 1999. This is a
result of higher freight and distribution expenses as well as higher sales and
marketing costs.

         OTHER EXPENSES

         The Company's other expenses for the first three months of 2000
increased by 1% ($1 million) over the comparable period of 1999. General
corporate expenses decreased by $2 million and operating interest expense
decreased by $3 million primarily due to the change in the mix of debt
instruments at March 31, 2000 versus March 31, 1999. The decreases in general
corporate and operating interest expenses in 2000 were offset by the $6 million
of interest expense related to the settlement of the OIG investigation in
February 2000.

         INCOME TAX RATE

         The effective tax rate from operations for the first three months of
2000 (48.7%) is lower than the rate for the comparable period of 1999 (53.1%),
due to higher earnings in relation to the amount of non-deductible merger
goodwill.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's cash requirements, including acquisitions, have
historically been funded by cash generated from operations.

         Net cash flows provided by operating activities totaled $61 million in
2000 compared to $72 million in 1999. This decrease is due primarily to a $5
million increase in earnings, $5 million add back of non-cash items, and the
collection of $38 million for the IDPN accounts receivable. These increases in
cash from net income adjusted for non-cash items and the collection of IDPN
receivables were offset by a $59 million change in other working capital
primarily related to an increase in accounts receivable and a decrease in
accrued liabilities. The increase in accounts receivable balances is primarily
due to the increase in days sales outstanding resulting from slower payment
patterns from third parties,



                                       17
<PAGE>   18


specifically from managed care plans. The decrease in accrued liabilities is
primarily due to timing of payments for accrued salaries and benefits and
unreconciled payments. Cash on hand was $16 million at March 31, 2000 compared
to $14 million at March 31, 1999.

         Under the final settlement with the government, the Company is required
to make net settlement payments totaling approximately $427 million, of which
$14 million had previously been paid prior to 2000. This net amount includes
approximately $59.2 million for Medicare receivables from the Government. During
the first quarter of 2000, the Company made initial payments to the Government
of $286 million and received $38 million from the Government for the Company's
outstanding Medicare receivables for the intradialytic parenteral nutrition
therapy relating to the Settlement.

         Under the definitive agreements with the Government, the Company
entered into a note payable for the settlement payment obligations to the
Government. Interest on installment payments to the Government will accrue at
6.3% on $51.2 million of the obligation and at 7.5% annually on the balance,
until paid in full.

         Under the terms of the note payable, the remaining obligations will be
paid in six quarterly installments beginning April 2000 and ending July 2001.
The first four quarterly installments will be made in the amount of $35.4
million including interest at 7.5%. The remaining two installments of $27.8
million including interest at 6.3% will be made in April and July 2001,
respectively. The Government will remit the balance of the Company's outstanding
Medicare receivables in four quarterly payments of $5.2 million plus interest at
7.5%.

         Net cash flows used in investing activities of operations totaled $56
million in 2000 compared to $22 million in 1999. The Company funded its
acquisitions and capital expenditures primarily through cash flows from
operations and intercompany borrowings. Acquisitions totaled $35 million and $5
million in 2000 and 1999, respectively, net of cash acquired. Capital
expenditures of $20 million and $17 million were made for internal expansion,
improvements, new furnishings and equipment in 2000 and 1999, respectively. The
Company intends to continue to enhance its presence in the U.S. by focusing its
expansion on the acquisition of clinics, expansion of existing clinics, and
opening of new clinics.

         Net cash flows used in financing activities of operations totaled $2
million in 2000 compared to $42 million in 1999. During the first three months
of 2000, the Company made payments to the government totaling $286 million for
the Settlement. Additionally, the increase in borrowings of $297 million is due
primarily to an intercompany note payable entered into with Franconia
Acquisition, LLC ($344 million), a wholly-owned subsidiary of FMC, offset by
payments on intercompany borrowings. The Company expects to use a portion of
these borrowings to finance future acquisitions.

CONTINGENCIES

         The Company is a plaintiff in litigation against the federal government
with respect to the implementation of OBRA 93 is seeking to change a proposed
revision to IDPN coverage policies, and is a defendant in significant commercial
insurance litigation. An adverse outcome in any of these matters, could have a
material adverse effect on the Company's business, financial condition and
results of operations. Because of the significant complexities and uncertainties
associated with these proceedings, neither an estimate of the possible loss or
range of loss the Company may incur in respect of such matters nor a reserve
based on any such estimate can be reasonably made. See - Note 5, "Commitments
and Contingencies".

         The Company believes that its existing credit facilities, cash
generated from operations and other current sources of financing are sufficient
to meet its foreseeable needs. If cash flows from operations or availability
under existing banking arrangements fall below expectations, the Company may be
required to consider other alternatives to maintain sufficient liquidity. There
can be no assurance that the Company will be able to do so on satisfactory
terms, if at all. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Liquidity and Capital Resources."

IMPACT OF INFLATION

         A substantial portion of the Company's net revenue is subject to
reimbursement rates which are regulated by the federal government and do not
automatically adjust for inflation. Non-governmental payors also are exerting
downward pressure on reimbursement levels. Increased operating costs that are
subject to inflation, such as labor and supply costs, without a compensating
increase in reimbursement rates, may adversely affect the Company's business and
results of operations.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company is exposed to market risks due to changes in interest rates
and foreign currency rates. The Company uses derivative financial instruments,
including interest rate swaps and foreign exchange contracts, as part of its
market risk management strategy. These instruments are used as a means of
hedging exposure to interest rate and foreign currency fluctuations in
connection with debt obligations and purchase commitments. The Company does not
hold or issue derivative instruments for trading or speculative purposes.

         Hedge accounting is applied if the derivative reduces the risk of the
underlying hedged item and is designated at inception as a hedge. Additionally,
changes in the value of the derivative must result in payoffs that are highly
correlated to the changes in value of the hedged item. Derivatives are measured
for effectiveness both at inception and on an ongoing basis.

         The Company enters into foreign exchange contracts that are designated
as, and effective as, hedges for firmly committed purchases. Also, since the
Company carries a substantial amount of floating rate debt, the Company uses
interest rate swaps to synthetically change certain variable-rate debt
obligations to fixed-rate obligations, as well as options to mitigate the impact
of interest rate fluctuations.

         Gains and losses on foreign exchange contracts accounted for as hedges
are deferred in other current assets or liabilities. The deferred gains and
losses are recognized as adjustments to the underlying hedged transaction when
the future sales or purchases are recognized. Interest rate swap payments and
receipts are recorded as part of interest expense. The fair value of the swap
contracts is not recognized in the financial statements. Cash flows from
derivatives are recognized in the consolidated statement of cash flows in the
same category as the item being hedged.

         If a derivative instrument ceases to meet the criteria for deferral,
any subsequent gains or losses are recognized in operations. If a firm
commitment does not occur, the foreign exchange contract is terminated and any
gain or loss is recognized in operations. If a hedging instrument is sold or
terminated prior to maturity, gains or losses continue to be deferred until the
hedged item is recognized. Should a swap be terminated while the underlying
obligation remains outstanding, the gain or loss is capitalized as part of the
underlying obligation and amortized into interest expense over the remaining
term of the obligation.

                                     PART II

                                OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

         DISTRICT OF MASSACHUSETTS

         With one exception, each of the qui tam or whistleblower actions which
served as the basis for the recently settled federal government investigation
were dismissed as a result of the Settlement. The exception is a portion of a
qui tam proceeding filed in the United States District Court for the Middle
District of Tennessee on December 15, 1994. That action was transferred to the
United States District Court for the District of Massachusetts in 1995, and
disclosed to the Company in September 1999. The portion of this qui tam action
that was not dismissed as a result of the settlement alleges, among other
things, that the Company violated the Medicare and Medicaid Anti-kickback
Statute by providing discounted hemodialysis products to induce the purchase of
laboratory services. In the Settlement Agreements, the U. S. government has
declined to continue to pursue further the investigation or prosecution of these
allegations. The government and the current and former employees who filed this
qui tam action, called "relators," offered to dismiss this portion of this qui
tam action in connection with the settlement. However, this offer required that
the Company grant a full release of all of the Company's claims against the
relators, and the Company is unwilling to do so. While there can be no
assurance, the Company believe that the resolution of these remaining
allegations will not have a material adverse impact on the Company's business,
financial condition or results of operations.

         COMMERCIAL INSURER LITIGATION

         In 1997, the Company, NMC, and certain named NMC subsidiaries, were
served with a civil complaint filed by Aetna Life Insurance Company in the U.S.
District Court for the Southern District of New York. Based in large part on
information contained in prior reports filed by the Company with the Securities
and Exchange Commission, the lawsuit alleges inappropriate billing practices for
nutritional therapy, diagnostic and clinical laboratory tests and
misrepresentations. In April 1999, Aetna amended its complaint to include its
affiliate, Aetna U.S. Healthcare, Inc., as an additional plaintiff, and to make
certain other limited changes in its pleading. The amended complaint seeks
unspecified damages and costs. In February 2000, the Company was served with a
similar complaint filed by Connecticut General Life Insurance Company, Equitable
Life Assurance Society of the United States, Cigna Employee Benefits Services,
Inc. and Guardian Life Insurance Company of America, Inc. (Connecticut General
Life Insurance Company et al v. National Medical Care et al, 00-Civ-0932)
seeking unspecified damages and costs. However, the Company, NMC and its
subsidiaries believe that there are substantial defenses to the claims asserted,
and intend to vigorously defend both lawsuits. Other private payors have
contacted the Company and may assert that NMC received excess payment and,
similarly, may join either lawsuit or file their own lawsuit seeking
reimbursement and other damages.

         In May 1999, the Company filed counterclaims against Aetna Life
Insurance Company and Aetna U.S. Healthcare, Inc. based on inappropriate claim
denials and delays in claim payments. The Company is investigating similar
counterclaims against other private payors that have filed a complaint or
contacted them. An adverse result of these litigations could have a material
adverse effect on the Company's business, financial position and result of
operations.

         Although the ultimate outcome on the Company of these proceedings
cannot be predicted at this time, an adverse result could have a material
adverse effect on the Company's business, financial condition and result of
operations.

         OBRA 93

         The Omnibus Budget Reconciliation Act of 1993 affected the payment of
benefits under Medicare and employer health plans for dual-eligible ESRD
patients. In July 1994, the Health Care Financing Administration issued an
instruction to Medicare claims processors to the effect that Medicare benefits
for the patients affected by that act would be subject to a new 18-month
"coordination of benefits" period. This instruction had a positive impact on
NMC's dialysis revenues because, during the 18-month coordination of benefits
period, patients' employer health plans were responsible for payment, which was
generally at rates higher than those provided under Medicare.

         In April 1995, the Health Care Financing Administration issued a new
instruction, reversing its original instruction in a



                                       20
<PAGE>   21


manner that would substantially diminish the positive effect of the original
instruction on NMC's dialysis business. The Health Care Financing Administration
further proposed that its new instruction be effective retroactive to August
1993, the effective date of the Omnibus Budget Reconciliation Act of 1993.

         NMC ceased to recognize the incremental revenue realized under the
original instruction as of July 1, 1995, but it continued to bill employer
health plans as primary payors for patients affected by the Omnibus Budget
Reconciliation Act of 1993 through December 31, 1995. As of January 1, 1996, NMC
commenced billing Medicare as primary payor for dual eligible ESRD patients
affected by the act, and then began to re-bill in compliance with the revised
policy for services rendered between April 24 and December 31, 1995.

         On May 5, 1995, NMC filed a complaint in the U.S. District Court for
the District of Columbia (National Medical Care, Inc. and Bio-Medical
Applications of Colorado, Inc. d/b/a Northern Colorado Kidney Center v. Shalala,
C.A. No.95-0860 (WBB) seeking to preclude the Health Care Financing
Administration from retroactively enforcing its April 24, 1995 implementation of
the Omnibus Budget Reconciliation Act of 1993 provision relating to the
coordination of benefits for dual eligible ESRD patients. On May 9, 1995, NMC
moved for a preliminary injunction to preclude the Health Care Financing
Administration from enforcing its new policy retroactively, that is, to billing
for services provided between August 10, 1993 and April 23, 1995. On June 6,
1995, the court granted NMC's request for a preliminary injunction and in
December of 1996, NMC moved for partial summary judgment seeking a declaration
from the Court that the Health Care Financing Administration's retroactive
application of the April 1995 rule was legally invalid. The Health Care
Financing Administration cross-moved for summary judgment on the grounds that
April 1995 rule was validly applied prospectively. In January 1998, the court
granted NMC's motion for partial summary judgment and entered a declaratory
judgment in favor of NMC, holding the Health Care Financing Administration's
retroactive application of the April 1995 rule legally invalid. Based on its
finding, the Court also permanently enjoined the Health Care Financing
Administration from enforcing and applying the April 1995 rule retroactively
against NMC. The Court took no action on the Health Care Financing
Administration's motion for summary judgment pending completion of the
outstanding discovery. On October 5, 1998, NMC filed its own motion for summary
judgment requesting that the Court declare the Health Care Financing
Administration's prospective application of the April 1995 rule invalid and
permanently enjoin Health Care Financing Administration from prospectively
enforcing and applying the April 1995 rule. The Court has not yet ruled on the
parties' motions. The Health Care Financing Administration elected not to appeal
the Court's June 1995 and January 1998 orders. The Health Care Financing
Administration may, however, appeal all rulings at the conclusion of the
litigation. If the Health Care Financing Administration should successfully
appeal so that the revised interpretation would be applied retroactively, NMC
may be required to refund the payment received from employer health plans for
services provided after August 10, 1993 under the Health Care Financing
Administration's original implementation, and to re-bill Medicare for the same
services, which would result in a loss to NMC of approximately $120 million
attributable to all periods prior to December 31, 1995. Also, in this event, the
Company's business, financial condition and results of operations would be
materially adversely affected.

         STATE OF FLORIDA

         In October 1999, NMC received an Antitrust Civil Investigative Demand
("CID") from the Attorney General of the State of Florida ("Florida AG") . The
CID was issued by the Florida AG in the course of an investigation to determine
whether there is, has been, or may be a violation of federal and Florida laws
resulting from the possible monopolization of, or the entering into agreement in
restraint of, trade relating to the provision of dialysis products and services
in Florida.

         The Company is cooperating with the Florida AG's investigation by
providing documents and other information to them. The impact of this
investigation on the business and financial condition, if any, cannot be
determined at this time.

         OTHER LITIGATION AND POTENTIAL EXPOSURES

         The Company, like other health care providers, conducts its operations
under intense government regulation and scrutiny. The Company must comply with
regulations which relate to or govern the safety and efficacy of medical
products and supplies, the operation of manufacturing facilities, laboratories
and dialysis clinics, and environmental and occupational health and safety. The
Company must also comply with the U.S. anti-kickback statute, the False Claims
Act, the Stark Law, and other federal and state fraud and abuse laws. Applicable
laws or regulations may be amended, or enforcement agencies or courts may make
interpretations that differ from the Company's or the manner in which the
Company conduct its business. In the U.S., enforcement has become a high
priority for the federal government and some states, due in part to budgetary
constraints on the government reimbursement programs



                                       21
<PAGE>   22

and the high level of visibility accorded to government efforts to deal with
alleged fraud and abuse. In addition, the provisions of the False Claims Act
authorizing payment of a portion of any recovery to the party bringing the suit
encourage private plaintiffs commence "whistle blower" actions. By virtue of
this regulatory environment, as well as our corporate integrity agreement with
the government, the Company expects that its business activities and practices
will continue to be subject to expensive review by regulatory authorities, and
the Company cannot exclude the possibility of additional inquiries, claims and
litigation relating to its compliance with applicable laws and regulations. The
Company may not always be aware that an inquiry or action has begun,
particularly in the case of "whistle blower" actions, which are initially filed
under court seal.

         The Company operates a large number and wide variety of facilities
throughout the U.S. In such a decentralized system, it is often difficult to
maintain the desired level of oversight and control over the thousands of
individuals employed by many affiliate companies. The Company relies upon its
management structure, regulatory and legal resources, and the effective
operation of its compliance program to direct, manage and monitor the activities
of these employees. However, on occasion, the Company has identified instances
where employees, deliberately or inadvertently, have submitted inadequate or
false billings. The illegal actions of such persons may subject the Company and
its subsidiaries to liability under the False Claims Act, among other laws, and
the Company cannot predict whether law enforcement authorities may use such
information to initiate further investigations of the business practices
disclosed or any of its other business activities.

         Physicians, hospitals and other participants in the health care
industry are also subject to a large number of lawsuits alleging professional
negligence, malpractice, product liability, worker's compensation or related
claims, many of which involve large claims and significant defense costs. The
Company has been subject to these suits due to the nature of its business and
the Company expects that those types of lawsuits may continue. Although the
Company maintains insurance at a level which it believes to be prudent, the
Company cannot assure that the coverage limits will be adequate or that
insurance will cover all asserted claims. A successful claim against the Company
or any of its subsidiaries in excess of insurance coverage could have a material
adverse effect upon the Company and the results of its operations. Any claims,
regardless of their merit or eventual outcome, also may have a material adverse
effect on the Company's reputation and business.

                     Amendment #2 dated March 27, 2000 to Agreement No. 19984813

- --------------------------------------------------------------------------------

Agreement No. 19984813, between Amgen Inc. ("Amgen") and National Medical Care,
Inc., including any prior amendments thereto, shall be amended, and for the
period commencing 1/1/2000 shall be restated in its entirety to read as stated
below.

This Agreement ("Agreement"), between Amgen Inc. ("Amgen") and National Medical
Care, Inc., including its subsidiaries and affiliates that are at least fifty
and one-tenth percent (50.10%) owned by National Medical Care, Inc. listed on
Appendix B, (collectively, "NMC"), sets forth the terms and conditions for the
purchase of EPOGEN(R) (Epoetin alfa) by NMC.

1.   TERM OF AGREEMENT. The "Term" of this Agreement shall be defined as January
     1, 2000 ("Commencement Date") through December 31, 2000 ("Termination
     Date").

2.   QUALIFIED PURCHASES. All terms contained herein apply only to purchases
     made hereunder, as confirmed by Amgen ("Qualified Purchases"), by NMC and,
     subject to the terms of Section 13, to all affiliates opened, acquired, or
     managed by NMC during the Term, for so long as such affiliates remain at
     least fifty and one-tenth percent (50.10%) owned or managed by National
     Medical Care, Inc. ("Affiliates"), through wholesalers chosen by NMC and
     authorized by Amgen to participate in the program ("Authorized
     Wholesalers") or directly from Amgen. In addition, and also subject to the
     terms of Section 13, Affiliates of Renaissance Health Care, Clinic, Inc.,
     Optimal Renal Care, L.L.C., Integrated Renal Care of the Pacific, and/or
     any joint venture of NMC in which NMC holds at least a fifty and one-tenth
     percent (50.10%) ownership interest, will also be eligible to participate,
     although not required to purchase. Amgen agrees to reasonably approve
     Authorized Wholesalers requested by NMC. The option to purchase on a direct
     basis from Amgen is subject to receipt and approval, not to be unreasonably
     withheld, of an "Application for Direct Ship Account".

3.   PRICING. See Appendix A.

4.   PAYMENT TERMS. The terms and conditions of this Agreement shall apply
     whether NMC and/or Affiliates purchase EPOGEN(R) through an Authorized
     Wholesaler or from Amgen directly.

5.   PRODUCT ACQUISITION COSTS. As long as NMC and Affiliates are the [DELETED],
     non-governmental, freestanding dialysis center (including home dialysis
     affiliates) purchaser of EPOGEN(R) in the United States, Puerto Rico and
     Guam during the Term, on an annual, calendar year basis, Amgen commits that
     this Agreement provides NMC and Affiliates with [DELETED] for EPOGEN(R)
     available to any freestanding dialysis center purchaser in the United
     States and Puerto Rico with comparable growth and percentage of patients
     with hematocrit levels greater than or equal to [DELETED]. If NMC and
     Affiliates are not the [DELETED] non-governmental, freestanding dialysis
     center purchaser of EPOGEN(R) in the United States, Puerto Rico and Guam
     during the Term, on a calendar year basis, Amgen may provide [DELETED] for
     EPOGEN(R) to [DELETED] non-governmental, freestanding dialysis center
     purchaser(s). Qualification as a freestanding dialysis center shall be
     determined by Amgen in its reasonable discretion, in accordance with
     Amgen's customer classification policies, which generally classify
     freestanding dialysis centers as independent, exclusive providers of
     dialysis services, which (a) may not obtain EPOGEN(R) from or through a
     hospital, or (b) are not otherwise affiliated with a hospital, nursing
     home, or integrated health care system. This commitment excludes [DELETED]
     available to any governmental entities, or [DELETED] mandated by Title 38
     (Veterans' Benefits) or Title 42 (The Public Health and Welfare) of the
     United States Code, or any other federal or state health care program.
     Amgen's agreement to make this commitment is contingent upon its ability to
     comply with all federal, state, local and military laws, statutes and
     regulations.

6.   MINIMUM PRODUCT PURCHASE AGREEMENT. NMC and Affiliates agree to purchase a
     minimum of [DELETED] of EPOGEN(R) from Amgen hereunder during each
     consecutive calendar quarter during the Term.

<PAGE>   2
7.   DISCOUNT. Amgen will pay discounts and incentives in accordance with the
     schedule and terms set forth in Appendix A attached hereto.


8.   PAYMENT OF DISCOUNTS. Any discount (hereinafter defined as including a
     discount at time of purchase, rebate, incentive or other concession
     impacting the pricing of a product) earned hereunder shall be calculated in
     accordance with this Agreement, based on Qualified Purchases, using
     [DELETED] as the calculation price, and shall be paid in the form of a wire
     transfer to NMC's corporate headquarters, except as otherwise provided. NMC
     and Affiliates shall make available to Amgen any records concerning NMC's
     and Affiliates' purchase amounts that Amgen or its auditors may reasonably
     request. Amgen shall make available to NMC any records concerning NMC's and
     Affiliates' purchase amounts that NMC or its auditors may reasonably
     request. [DELETED] Amgen will use its best efforts to make any discount
     (excluding discounts at time of purchase) pursuant to this Agreement
     available in accordance with the terms referenced in Appendix A.
     Availability of discounts is contingent upon Amgen receiving all relevant
     purchase data from all Authorized Wholesalers designated by NMC, in a form
     reasonably acceptable to Amgen, detailing NMC's and Affiliates' Qualified
     Purchases of EPOGEN(R) for the relevant period, along with any other data
     required by the terms of Appendix A. In the event of any purchases directly
     from Amgen, all such purchase data shall be included in the calculation of
     all discounts. In no event shall Amgen pay any discount on EPOGEN(R)
     distributed by NMC or Affiliates to non-Affiliates of NMC (see Section 2
     for definition of Affiliates). Subject to the section entitled "Breach of
     Agreement", in the event that Amgen is notified in writing that National
     Medical Care, Inc. and/or any of its subsidiaries or Affiliates (the
     "Acquiree") is acquired by another entity or a change of control otherwise
     occurs with respect to the Acquiree, any discount which may have been
     earned hereunder prior to the effective date of the acquisition shall
     vest, and shall be paid in the form of a wire transfer to NMC's corporate
     headquarters subject to the conditions described herein.

9.   TREATMENT OF DISCOUNTS. The parties agree that they will account for any
     discount earned hereunder in a way that complies with all applicable
     federal, state, and local laws and regulations, including without
     limitation, Section 1128B(b) of the Social Security Act and its
     implementing regulations, and if required by such statutes or regulations
     (a) claim the benefit of such discount received, in whatever form, in the
     fiscal year in which such discount was earned or the year after, (b) fully
     and accurately report the value of such discount in any cost reports filed
     under Title XVIII or Title XIX of the Social Security Act, or a state
     health care program, and (c) provide, upon request by the U.S. Department
     of Health and Human Services or a state agency or any other federally
     funded state health care program, the information furnished by Amgen
     concerning the amount or value of such discount. NMC agrees that it will
     advise all Affiliates, in writing, of any discount received by NMC's
     corporate headquarters hereunder with respect to purchases made by such
     Affiliates and that NMC will advise said Affiliates as to their requirement
     to account for any such discount in accordance with the above stated
     requirements.

10.  COMMITMENT TO PURCHASE. NMC and Affiliates agrees to purchase EPOGEN(R) for
     all of its dialysis use requirements in the United States, Puerto Rico and
     Guam for recombinant human erythropoietin. Amgen agrees to make such
     EPOGEN(R) available to NMC and Affiliates through its Authorized
     Wholesalers or directly from Amgen. In addition to other remedies available
     to NMC and Affiliates, NMC and Affiliates may purchase another brand of
     recombinant human erythropoietin for its dialysis use requirements in the
     United States, Puerto Rico and Guam if, and only if, NMC and Affiliates
     have informed Amgen, in writing, that NMC and Affiliates are unable to
     acquire sufficient amounts of EPOGEN(R) to meet NMC's and Affiliates'
     reasonable dialysis use requirements, and Amgen by itself, or through its
     Authorized Wholesalers, is actually unable to supply NMC and Affiliates
     with their reasonable dialysis use requirements of EPOGEN(R) within the
     time period reasonably required by NMC and Affiliates, which, in no event
     will be less than five (5) business days after Amgen's receipt of NMC's and
     Affiliates' written notice. If the preceding requirements are met, NMC and
     Affiliates will only be allowed to purchase another brand of recombinant
     human erythropoietin for the time period, and to the extent, that Amgen is
     unable to provide NMC and Affiliates with EPOGEN(R) to meet NMC's and
     Affiliates' reasonable dialysis use requirements.

11.  OWN USE. NMC hereby certifies that EPOGEN(R) purchased hereunder will be
     for the "own use" by NMC and the Affiliates of NMC.

12.  AUTHORIZED WHOLESALERS. A complete list of NMC's and Affiliates' current
     Authorized Wholesalers, through whom NMC and Affiliates may purchase
     EPOGEN(R) hereunder is attached as Appendix C. NMC and Affiliates agrees to
     promptly

<PAGE>   3
     provide Amgen with any additions, deletions, or changes to the initial list
     of Authorized Wholesalers. Amgen requires no less than 30 days notice
     before the effective date of change for any addition or deletion of
     Authorized Wholesalers hereunder. Any proposed changes to the initial list
     of Authorized Wholesalers must be in writing and are subject to reasonable
     approval by Amgen.

13.  SUBSIDIARIES AND AFFILIATES. Within 30 days of execution of this Agreement,
     NMC shall provide a current listing of all Affiliates, and other entities,
     that will be participating in this Agreement, designating which Affiliates
     are owned and/or managed by NMC. Such listing will be incorporated into
     this Agreement as Appendix B. Only those entities listed on Appendix B will
     be eligible to participate in this Agreement. Any NMC managed Affiliate, or
     other entity with an existing contract, may participate in either their
     existing agreement with Amgen, or this Agreement, but not both. Each
     managed Affiliate or entity must declare under which single Amgen contract
     it will participate. Only Qualified Purchases under this Agreement will be
     used in the calculation of pricing, discounts or other incentives under
     this Agreement. NMC will notify Amgen of changes to Appendix B, and the
     effective date of change. Such effective date of change may not be earlier
     than the date the notice is received by Amgen. Any proposed change to
     Appendix B will be subject to the reasonable approval of Amgen based upon
     Amgen's then current legal and contractual requirements, and such proposed
     affiliate's classification as a freestanding dialysis center or a home
     dialysis support facility.

14.  BREACH OF AGREEMENT. Either party may terminate this Agreement for a
     material breach upon thirty (30) days advance written notice provided such
     breach remains uncured at the end of the thirty (30) day period.

15.  CONFIDENTIALITY. Both Amgen and NMC agree that this Agreement represents
     and contains confidential information which will not be disclosed to any
     third party, or otherwise made public, without prior written authorization
     of the other party, except where such disclosure is contemplated hereunder
     or required by law or court order. In the event NMC believes it is
     obligated to disclose any such information as required by law or court
     order, NMC will provide Amgen with prior written notice and an opportunity
     to seek a protective order and NMC shall furnish only that portion of the
     information that its counsel advises is required to be disclosed by law.

16.  WARRANTIES. Each party represents and warrants to the other that this
     Agreement (a) has been duly authorized, executed, and delivered by it, (b)
     constitutes a valid, legal, and binding agreement enforceable against it in
     accordance with the terms contained herein, and (c) does not conflict with
     or violate any of its other contractual obligations, expressed or implied,
     to which it is a party or by which it may be bound. NMC represents and
     warrants that it has the power to bind National Medical Care, Inc. and the
     subsidiaries and owned Affiliates listed on Appendix B to the terms
     contained herein. NMC shall cause each managed Affiliate to be bound by the
     terms and conditions of this Agreement through the execution of a joinder
     agreement executed between NMC and each such managed Affiliate.

17.  GOVERNING LAW. This Agreement will be governed by the laws of the State of
     Delaware and the parties submit to the jurisdiction of Delaware courts,
     both state and federal.

18.  NOTICES. Any notice or other communication required or permitted hereunder
     will be in writing and shall be deemed given or made when delivered in
     person or when received by the other party sent by U.S. Mail, return
     receipt requested, at the respective party's address set forth below or at
     such other address as the party shall have furnished to the other in
     accordance with this provision.

19.  COMPLIANCE WITH HEALTH CARE PRICING LEGISLATION AND STATUTES.
     Notwithstanding anything contained herein to the contrary, at any time
     following the enactment of any federal, state, or local law or regulation
     that materially reforms, modifies, alters, restricts, or otherwise affects
     the pricing of or reimbursement available for EPOGEN(R), either party may
     initiate good faith negotiations to modify this Agreement. If after
     forty-five (45) days the parties are unable to in good faith mutually agree
     to modifications to this Agreement, (a) either party may terminate this
     Agreement immediately, or (b) Amgen may exclude any owned or managed
     Affiliates from participating in this Agreement unless such owned or
     managed Affiliate(s) certifies in writing that they are, or will be, exempt
     from the provisions of such enacted law or

<PAGE>   4
     regulation. Additionally, in order to assure compliance with any existing
     federal, state or local statute, regulation or ordinance, Amgen reserves
     the right, in its reasonable discretion, to exclude any owned or managed
     Affiliates from the pricing, discount, and incentive provisions of this
     Agreement. In the event there is a future change in Medicare, Medicaid, or
     other federal or state statutes or regulations or in the interpretation
     thereof, which renders any of the material terms of this Agreement unlawful
     or unenforceable, this Agreement shall continue and shall be amended by the
     parties as a result of good faith negotiations as necessary to bring the
     Agreement into compliance with such statute and regulation.

20.  MISCELLANEOUS. No modification of this Agreement shall be effective unless
     made in writing and signed by a duly authorized representative of each
     party. This Agreement constitutes the entire agreement of the parties
     pertaining to the subject matter hereof and supersedes all prior written
     and oral agreements and understandings pertaining hereto including without
     limitation, any previous or existing contract or amendment for the purchase
     of EPOGEN(R). Neither party shall have the right to assign this Agreement
     to a third party without the prior written consent of the other party.
     Neither party shall be liable for delays in performance and nonperformance
     of this Agreement or any covenant contained herein caused by fire, flood,
     storm, earthquake or other act of God, war, rebellion, riot, failure of
     carriers to furnish transportation, strike, lockout or other labor
     disturbances, act of government authority, inability to obtain material or
     equipment, or any other cause of like or different nature beyond the
     control of such party. However, during any time of nonperformance by Amgen
     which involves NMC's and Affiliates' inability to obtain sufficient
     EPOGEN(R) to meet NMC's and Affiliates' reasonable dialysis use
     requirements the [DELETED] for such nonperformance, the [DELETED] and NMC
     and Affiliates may purchase EPOGEN(R) from another supplier. The parties
     shall execute and deliver all documents, provide all information, and take
     or refrain from taking action as may be necessary or appropriate to achieve
     the purposes of this Agreement. This Agreement may be executed in one or
     more counterparts, each of which is deemed to be an original but all of
     which taken together constitutes one and the same agreement. Amgen reserves
     the right to rescind this offer if the parties fail to execute this
     Agreement within thirty (30) days from the date of its offering.

Please retain one fully executed original for your records and return the other
fully executed original to Amgen.

         i)       facility ID, [DELETED] [DELETED] for EPOGEN(R), [DELETED],
                  treatment date, [DELETED], [DELETED], [DELETED], [DELETED],
                  [DELETED], EPOGEN(R) dose (collectively the "Data"). Amgen may
                  utilize the Data for any purpose, and reserves the right to
                  audit all Data. Notwithstanding the foregoing, Amgen shall not
                  sell or re-sell any Data obtained pursuant to this Agreement.
                  Additionally, any use by Amgen of such Data shall be in a
                  format that does not identify NMC as the source of such Data,
                  unless NMC has consented to such use. Under no circumstances
                  should the Data include any patient identifiable information
                  including, without limitation, name, complete social security

                  acceptable to Amgen. Hand written reports are not acceptable;
                  electronic submission of the Data is preferred; and

         ii)      [DELETED] and

         iii)     a properly executed "Annual Certification Letter", a sample of
                  which is attached hereto as Exhibit #1, that will be provided
                  to NMC's corporate headquarters, unless otherwise requested,
                  after this Agreement is executed by both parties.

         *NOTWITHSTANDING THE REQUIREMENT TO SUBMIT DATA ON A [DELETED] BASIS
REFERENCED ABOVE, THE [DELETED] DATA ELEMENTS REFERENCED IN 2a ii) ABOVE SHALL
BE REQUIRED FOR THE [DELETED] WITHIN [DELETED] DAYS FOLLOWING THE END OF THE
[DELETED]. COMMENCING WITH THE [DELETED] OF [DELETED], THE DATA ELEMENTS SET
FORTH IN 2a ii) SHALL BE REQUIRED ON A [DELETED] BASIS AS SET FORTH IN THIS
SECTION 2A.

B.       CALCULATION: Assuming NMC and Affiliates have fulfilled all
         requirements as described in Section 2(a) above, NMC's [DELETED]
         payment will be calculated as follows: The "Average Patient [DELETED] "
         for each dialysis patient will be based upon the average of all
         [DELETED] gathered for each patient during each [DELETED] of the Term.
         The [DELETED] of all dialysis patients with Average Patient [DELETED]
         greater than or equal to [DELETED] will be determined by dividing the
         total number of dialysis patients with Average Patient [DELETED]
         greater than or equal to [DELETED] by the total number of dialysis
         patients treated by NMC and Affiliates. The [DELETED] will be
         calculated based on NMC's and Affiliates' overall performance in
         accordance with Amgen's discount calculation policies.

         Letter (attached hereto as Exhibit 1) and all required Data for the
         corresponding [DELETED]. Data shall be submitted to Amgen [DELETED] and

         the [DELETED] for that [DELETED]. [DELETED]. However, if Amgen
         determines that any Affiliate(s) is consistently not submitting the
         required Data, Amgen reserves the right in its reasonable discretion to
         exclude such Affiliate's Qualified Purchases of EPOGEN(R)from the
         calculation of the [DELETED] for any relevant [DELETED]. [DELETED]
         payments will be based on the Data received from the [DELETED], and
         will equal a percentage of NMC's and Affiliates' total Qualified
         Purchases of EPOGEN(R) during each relevant [DELETED] (exclusive of any
         Qualified Purchases of EPOGEN(R) made by NMC or any Affiliate not

     THE INITIAL TERM AND ANY SUBSEQUENT RENEWAL PERIODS SHALL BE CALLED THE
     "EMPLOYMENT TERM."

     and investor relations issues. EMPLOYEE shall to the best of his ability
     and experience competently, loyally, diligently and conscientiously perform
     all of the duties and obligations expressly or implicitly required under
     this Agreement. EMPLOYEE further agrees that, in conducting business in the
     interest of the EMPLOYER, he will not engage in, knowingly permit others
     under his control to carry on, or induce others to engage in any practice

     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

     ($400,000). EMPLOYEE will be provided with the opportunity to purchase

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.

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
                                        2
<PAGE>   3

     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.

     Additionally, this Agreement may be terminated by Employee, if there is a
     reduction in Employee's responsibilities or FMC experiences a change in
     control defined as any of the following: i) the transfer (whether by sale,
     dividend, exchange, lease, merger, consolidation or otherwise) of greater
     that 50 percent (50%) of the voting power of FMC; ii) the transfer (whether
     by sale, dividend, exchange, lease, merger, consolidation or otherwise) of
     all or substantially all the assets or stock of FMC; or iii) any other
     action which results in persons other than the current majority
     shareholders of FMC, having the voting power to direct the management of
     FMC or if FMC relocates its corporate headquarters more than fifty (50)
     miles from its present location in Lexington, Massachusetts.

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:

            (iii) The balance of the salary payments equivalent to the number of
                  months remaining in the term of the Employment Agreement. At a
                  minimum, the number of months for salary continuance would



                                       3
<PAGE>   4

                  be eighteen (18) 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

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

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



                                       4
<PAGE>   5


     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 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.



                                       5

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.

     competently, loyally, diligently and conscientiously perform all of the
     duties and obligations expressly or implicitly required under this
     Agreement. EMPLOYEE further agrees that, in conducting business in the
     interest of the EMPLOYER, he will not engage in, knowingly permit others

     customary withholding and employment taxes. At the end of each year of

     shall be entitled to participate in FMC's Management Bonus Plan and any

     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

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.

     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 expense, with
     proof of good health.

f)   AUTOMOBILE. EMPLOYEE will be provided with a company car allowance of Seven

     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

     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.

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




                                       2
<PAGE>   3


     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.

      Additionally, this Agreement may be terminated by Employee, if there is a
      reduction in Employee's responsibilities or FMC experiences a change in
      control defined as any of the following: i) the transfer (whether by sale,
      dividend, exchange, lease, merger, consolidation or otherwise) of greater
      that 50 percent (50%) of the voting power of FMC; ii) the transfer
      (whether by sale, dividend, exchange, lease, merger, consolidation or
      otherwise) of all or substantially all the assets or stock of FMC; or iii)
      any other action which results in persons other than the current majority
      shareholders of FMC, having the voting power to direct the management of
      FMC or if FMC relocates its corporate headquarters more than fifty (50)
      miles from its present location in Lexington, Massachusetts.

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:

            (iii) The balance of the salary payments equivalent to the number of
                  months remaining in the term of the Employment Agreement. At a
                  minimum, the number of months for salary continuance would



                                       3
<PAGE>   4

                  be eighteen (18) 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

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

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



                                       4
<PAGE>   5


     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 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.



                                       5

     this Agreement, or cancellation or replacement of this Agreement shall be

     ($600,000) beyond the current policy of coverage at his own expense, with
     proof of good health.

     Additionally, this Agreement may be terminated by Employee, if there is a
     reduction in Employee's responsibilities or FMC experiences a change in
     control defined as any of the following: i) the transfer (whether by sale,
     dividend, exchange, lease, merger, consolidation or otherwise) of greater
     that 50 percent (50%) of the voting power of FMC; ii) the transfer (whether
     by sale, dividend, exchange, lease, merger, consolidation or otherwise) of
     all or substantially all the assets or stock of FMC; or iii) any other
     action which results in persons other than the current majority
     shareholders of FMC, having the voting power to direct the management of
     FMC or if FMC relocates its corporate headquarters more than fifty (50)
     miles from its present location in Lexington, Massachusetts.

f)   AUTOMOBILE. EMPLOYEE will be provided with a company car allowance of Seven
     Hundred Dollars ($700) paid monthly and treated as ordinary income.

g)   FINANCIAL PLANNING/TAX PREPARATION. EMPLOYEE will be provided with an
     allowance of Two Thousand Dollars ($2,000) to be paid based upon submitted
     documentation of expenses incurred as a result of financial planning
     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



                                       2
<PAGE>   3


     EMPLOYER at least thirty (30) days written notice if he wishes to terminate
     his employment pursuant to this provision.

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.

     Additionally, this Agreement may be terminated by Employee, if there is a
     reduction in Employee's responsibilities or FMC experiences a change in
     control defined as any of the following: i) the transfer (whether by sale,
     dividend, exchange, lease, merger, consolidation or otherwise) of greater
     that 50 percent (50%) of the voting power of FMC; ii) the transfer (whether
     by sale, dividend, exchange, lease, merger, consolidation or otherwise) of
     all or substantially all the assets or stock of FMC; or iii) any other
     action which results in persons other than the current majority
     shareholders of FMC, having the voting power to direct the management of
     FMC or if FMC relocates its corporate headquarters more than fifty (50)
     miles from its present location in Lexington, Massachusetts.

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



                                       3
<PAGE>   4


                  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:

            (iii) The balance of the salary payments equivalent to the number of
                  months remaining in the term of the Employment Agreement. At a
                  minimum, the number of months for salary continuance would be
                  eighteen (18) 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

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

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



                                       4
<PAGE>   5

     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 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.


                                       5

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.

12.  NOTICES. Any notice, consent, request or other communication made or given
     in connection with this Agreement shall be in writing and shall be deemed
     to have been duly given when delivered or mailed by registered or certified
     mail, return receipt requested, to those listed below at their following
     respective addresses or at such other address as each may specify by notice

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.
