     III. TERMS AND CONDITIONS
          --------------------

     NOW, THEREFORE, in reliance on the representations contained herein and in
consideration of the mutual promises, covenants, and obligations in this
Agreement, and for good and valuable consideration, receipt of which is hereby
acknowledged, the Parties agree as follows:

     1.   NMC and FMCH, collectively, shall pay to the United States and the
Participating States, collectively, the sum of one hundred twelve million one

this sum shall constitute a debt immediately due and owing to the United States
upon the later of the dates on which (a) this Agreement is fully executed by the
Parties, (b) the notice of dismissal described in Paragraph 18 of this
Agreement is filed and docketed by the Court, or (c) the Court accepts LIFECHEM
and MPD's guilty pleas and the sentences set forth in their respective Plea
Agreements described in Preamble Paragraphs C and D (the "First Payment Date").
NMC and FMCH shall pay the Settlement Amount to the United States according to
the schedule, terms and instructions contained in the Promissory Note executed
contemporaneous with this Agreement, attached as Exhibit A, and incorporated by
reference.  Within a reasonable amount of time after receipt of the first
payment from NMC and FMCH pursuant to the terms of the Promissory Note, the
United States shall pay to the Participating States, collectively, according to
written payment instructions from the


Participating States, an amount of two million five hundred twenty seven
thousand one hundred thirty three dollars ($2,527,133) as the Participating
States' share of the Settlement Amount.

     2.   As an express condition of the Settlement Agreement, to secure NMC's
and FMCH's payment obligations under Paragraph 1 of this Agreement (and the
other civil Settlement Agreements and criminal Plea Agreements executed
contemporaneously), NMC and FMCH shall:

          a.   procure from the Bank of Nova Scotia and deliver or cause to be
delivered to the United States Attorney's Office for the District of
Massachusetts, on or before January 19, 2000, an amendment to the unconditional,
irrevocable Letter of Credit No. S020/43695/96 issued to the United States of
America on September 27, 1996 (the "Letter of Credit") to increase the amount of

shall be in the form attached as Exhibit B.  Within 10 days of receipt by the
U.S. Attorney's Office of written confirmation from the transferring bank that a
quarterly payment, as described in Paragraphs 1.B. through 1.E of the Promissory
Note, or prepayment of such quarterly payments, has been made to the United
States, the United States shall provide written permission to the Bank of Nova
Scotia to reduce the amount available for drawing under Letter of Credit No.
S020/43695/96 by the amount of the principal payment received.  In the event
that the entire outstanding payment obligation secured by the Letter of Credit
is prepaid, then the United States shall provide written permission to reduce
the amount available for drawing to zero.  The United States shall return the
Letter of Credit for cancellation when all obligations secured by it are paid in
full or it is determined, by the United States, or pursuant to a final and non-
appealable order of a court of competent jurisdiction, that NMC and FMCH have
fulfilled all such payment obligations to the United States; and

          b.   on January 19, 2000, NMC and FMCH shall establish an escrow

of $48,546 (through accrued interest and/or deposits), beginning on January 20,
2000 and continuing through April 15, 2000, when the escrow amount each day will
increase by an additional amount of $7,271 (through accrued interest and/or
deposits), for each quarterly payment due before the first payment is due on the
First Payment Date under the Promissory Note. On the First Payment Date all
funds in the escrow account shall be paid to the United States to satisfy the
payment obligation in Paragraph 1.A. of the Promissory Note. The terms and
conditions of this escrow account shall in no way limit NMC and FMCH's payment
obligations to the United States either pursuant to the Promissory Note or as
secured by the Letter of Credit.

     3.   NMC and FMCH are in default of this Agreement on the date of
occurrence of any of the following events ("Events of Default"):

1996, attached as Exhibit C.

          c.   The United States retains any and all other rights and remedies

through presentment against the Letter of Credit. NMC and FMCH recognize that
this express waiver is in consideration for the settlement of claims by the
United States described in Preamble Paragraphs K through Y above, under the
terms and conditions contained in this Settlement Agreement.


          b.   By expressly waiving the automatic stay provision, NMC and FMCH

(including bankruptcy courts) by the United States to exclude LIFECHEM and MPD
from participation in the Title XVIII (Medicare), Title XIX (Medicaid) programs,
and other federal health care programs;

          c.   This Agreement shall be voidable at the sole option of the United
States;

          d.   If any term(s) of this Agreement are set aside for any reason,
including as a result of a preference action brought pursuant to 11 U.S.C. (S)
547, the United States, at its sole option and in its discretion, may rescind
all terms of this Agreement and seek recovery of the full amount of claims and
allegations identified herein and in the Civil Action, or, in the alternative,
enforce the remaining terms of this Agreement. In the event of rescission of
this Agreement, all Parties reserve all rights, claims, and defenses that are
available under law and equity as of the Effective Date of this Agreement; and

          e.   In addition to the rights enumerated in Paragraph 8.a. through
8.d. above, the United States and all other Parties shall retain all rights and
claims they have or may have under law and equity.

     9.   Subject to the exceptions and limitations in Paragraph 10 below, in
consideration of the obligations of LIFECHEM, MPD, NMC and FMCH set forth in
this Agreement, conditioned upon payment in full of the Settlement Amount,
subject to Paragraph 29 below (concerning bankruptcy proceedings commenced
within 91 days of any payment under this Agreement), and subject to the
acceptance by the United States District Court for the District of Massachusetts
of LIFECHEM and MPD's guilty pleas as described in Preamble Paragraphs C and D,
the United States, on behalf of itself, and its officers, agents, agencies, and
departments, will release and will be deemed to have released LIFECHEM, MPD,
their parents, including NMC and FMCH, and the subsidiaries of NMC and FMCH
listed on the attached Exhibit D (collectively, the parents and subsidiaries of
NMC and FMCH listed on Exhibit D will be


referred to as the "NMC Companies," and the corporate entities listed on Exhibit
D comprise the only entities which constitute the "NMC Companies" within the
meaning of this Agreement), and the current directors, officers, employees, and
agents of the NMC Companies who were not employed by or in any way affiliated
with LIFECHEM, MPD, NMC, or NMC's parents, subsidiaries, divisions, or
affiliates at any time prior to September 30, 1996, from any civil or
administrative monetary claim (including recoupment claims) that the United
States has or may have under the False Claims Act, 31 U.S.C. (S)(S) 3729-3733;
the Program Fraud Civil Remedies Act, 31 U.S.C. (S)(S) 3801-3812; the Civil
Monetary Penalties Law, 42 U.S.C. (S) 1320a-7a; or common law claims for fraud,
payment by mistake of fact, breach of contract or unjust enrichment for the
conduct described in Preamble Paragraphs K through Y above with respect to
claims submitted or caused to be submitted to Medicare, Railroad Retirement
Medicare, TRICARE, FEHBP, the VA, and/or the Medicaid programs of the
Participating States.

     10.  Notwithstanding any term of this Agreement, the United States
specifically does not release LIFECHEM, MPD, the NMC Companies, or any
individual from any and all of the following:  (a) any potential criminal, civil
or administrative claims arising under Title 26, U.S. Code (Internal Revenue
Code); (b) any criminal liability; (c) any potential liability to the United
States (or any agencies thereof) for any conduct other than that identified in
Preamble Paragraphs K through Y above, including but not limited to any
allegations in the Civil Action not encompassed by Preamble Paragraphs K through
Y; (d) any entities not specifically included on the list of NMC Companies set
forth in Exhibit D, such omitted entities specifically including Spectra
Laboratories, Inc., SRC Holding Company, Inc. and their subsidiaries; (e) any
claims based upon such obligations as are created by this Agreement; (f) except
as explicitly stated in this Agreement, any administrative liability, including
mandatory exclusion from Federal health care programs; (g) any express or
implied warranty claims or other claims for defective or deficient products and
services provided by LIFECHEM or MPD, including quality of testing or


product claims; (h) any claims for personal injury or property damage or for
other consequential damages arising from the conduct described in Paragraphs K
through Y above; (i) any claims based upon failure to deliver items or services;
(j) any civil or administrative claims against any individual who was an
officer, director, trustee, agent, employee, or was in any way affiliated with
LIFECHEM, MPD, NMC, or NMC's parents, subsidiaries, divisions, or affiliates at
any time prior to September 30, 1996; or (k) any civil or administrative claims
against any individual, including current directors, officers, employees and
agents who is criminally indicted or convicted of an offense, or who enters a
criminal plea related to the conduct alleged in Preamble Paragraphs K through Y
above.

     11.  In compromise and settlement of the rights of OIG-HHS to exclude
LIFECHEM and MPD pursuant to 42 U.S.C. (S) 1320a-7(a)(1), both LIFECHEM and MPD
agree to be permanently excluded under this statutory provision from
participation in Medicare, Medicaid, and all other federal health care programs
as defined in 42 U.S.C. (S) 1320a-7b(f).  Such exclusion will have national
effect and will also apply to all other Federal procurement and non-procurement
programs.  Federal health care programs will not reimburse LIFECHEM and/or MPD
or any one else for items or services, including administrative and management
services, furnished, ordered or prescribed by LIFECHEM and MPD in any capacity.
Both LIFECHEM and MPD waive any further notice of this exclusion, other than the
notice described in the last sentence of this paragraph, and agree not to
contest such exclusion either administratively or in any State or Federal court.
If LIFECHEM or MPD submits or causes claims to be submitted for services
provided while excluded, LIFECHEM and MPD are subject to the imposition of
additional civil monetary penalties and assessments.  LIFECHEM and MPD further
agree to hold the federal programs, and all the federal programs' beneficiaries
and/or sponsors, harmless from any financial responsibility for services
furnished, ordered or prescribed to such beneficiaries or sponsors after the
effective date of this exclusion.  LIFECHEM and MPD specifically waive


their rights under any statute or regulation to payment from the Medicare,
Railroad Retirement Medicare, TRICARE, VA, FEHBP or Medicaid programs for
services rendered after the effective date of this exclusion. This exclusion
will be effective upon the date that LIFECHEM and MPD receive the notice of
exclusion from OIG-HHS.

     12.  FMCH, on behalf of itself and its parents, affiliates, subsidiaries,
and divisions, including but not limited to NMC, has entered into a Corporate
Integrity Agreement with HHS-OIG, which is incorporated into this Agreement by
reference.  FMCH will immediately upon execution of this Agreement implement its
obligations under the Corporate Integrity Agreement.

     13.  In consideration of the obligations of LIFECHEM, MPD, NMC and FMCH set
forth in this Agreement, conditioned upon payment in full of the Settlement
Amount, subject to Paragraph 29 below (concerning bankruptcy proceedings
commenced within 91 days of any payment under this Agreement), and conditioned
upon FMCH's entering into the Corporate Integrity Agreement, the OIG-HHS agrees
to release and refrain from instituting, directing, or maintaining any
administrative claim or any action seeking exclusion from the Medicare, Medicaid
or other Federal health care programs (as defined in 42 U.S.C. (S) 1320a-7b(f))
against the NMC Companies and the current directors, officers, employees, and
agents of the NMC Companies who were not employed by or in any way affiliated
with LIFECHEM, MPD, NMC, or any of NMC's parents, subsidiaries, divisions, or
affiliates at any time prior to September 30, 1996, under 42 U.S.C. (S) 1320a-7a
(Civil Monetary Penalties Law) or 42 U.S.C. (S) 1320a-7(b) (permissive
exclusion) for the conduct described in Preamble Paragraphs K through Y, except
as reserved in Paragraph 10 above and as reserved in this Paragraph. The OIG-HHS
expressly reserves all rights to comply with any statutory obligations to
exclude the NMC Companies from the Medicare, Medicaid, or other Federal health
care programs under 42 U.S.C. (S) 1320a-7(a)(mandatory exclusion). Nothing in
this Paragraph precludes the OIG-HHS from taking


action against entities or individuals for conduct and practices for which civil
claims have been reserved in Paragraph 10 above.

     14.  In consideration of the obligations of LIFECHEM, MPD, NMC and FMCH set
forth in this Agreement, conditioned upon payment in full of the Settlement
Amount, and subject to Paragraph 29 below (concerning bankruptcy proceedings
commenced within 91 days of any payment under this Agreement), TSO agrees to
release and refrain from instituting, directing, or maintaining any
administrative claim or any action seeking exclusion from the TRICARE program
against the NMC Companies and the current directors, officers, employees, and
agents of the NMC Companies who were not employed by or in any way affiliated
with LIFECHEM, MPD, NMC or NMC's subsidiaries, divisions, and affiliates at any
time prior to September 30, 1996, under 32 C.F.R. (S) 199.9 for the conduct
described in Preamble Paragraphs K through Y, except as reserved in Paragraph 10
above and as reserved in this Paragraph.  The TSO expressly reserves all rights
to comply with any statutory obligations to exclude the NMC Companies from the
TRICARE program under 32 C.F.R. (S)(S) 199.9(f)(1)(i)(A), (f)(1)(i)(B),
(f)(1)(i)(D), and (f)(1)(iii).  Nothing in this Paragraph precludes the TSO from
taking action against entities or persons, or for conduct or practices, for
which civil claims have been reserved in Paragraph 10 above.

     15.  In consideration of the obligations of LIFECHEM, MPD, NMC and FMCH as
set forth in this Agreement, conditioned upon payment in full of the Settlement
Amount, and subject to Paragraph 29 below (concerning bankruptcy proceedings
commenced within 91 days of any payment under this Agreement), OPM agrees to
release and refrain from instituting, directing, or maintaining any
administrative claim or any action seeking exclusion from FEHBP against the NMC
Companies  and the current directors, officers, employees, and agents of the NMC
Companies who were not employed by or in any way affiliated with LIFECHEM, MPD,
NMC or NMC's subsidiaries, divisions, or affiliates at any time prior to
September 30, 1996, under


5 U.S.C. (S) 8902a or 5 C.F.R. Part 970 for the conduct described in Preamble
Paragraphs K through Y including that in the Civil Action, except as reserved in
Paragraph 10 above, and except if the NMC Companies or any individuals are
excluded by the Office of Inspector General of HHS pursuant to 42 U.S.C. (S)
1320a-7(a). Nothing in this paragraph precludes OPM from taking action against
entities or persons, or for conduct and practice for which civil claims have
been reserved in Paragraph 10 above.

     16.  Jay A. Buford, William L. Schoff and Russell J. Davis each agree that
the settlement of the claims set forth in their Civil Action to the extent
encompassed by Preamble Paragraphs K through Y is fair, adequate and reasonable
under all the circumstances, pursuant to 31 U.S.C. (S) 3730(c)(2)(B).

     17.  The United States agrees to pay Jay A. Buford, William L. Schoff and
Russell L. Davis (the "Relators") collectively 16.5% of the federal share of the
Settlement Amount ($109,632,867) in a total principal amount of eighteen million
eighty-nine thousand four hundred twenty-three dollars ($18,089,423), plus 16.5%
of the interest paid by NMC and FMCH, if any.  To satisfy this obligation, the
United States will pay the Relators collectively 16.5% of the federal share of
the payments made by NMC and FMCH as they are received under the terms of the
Promissory Note, as more particularly set forth in Exhibit A to the Promissory
Note as those payments relate to this Agreement.  The first payment to Relators
will be made within 21 days after the First Payment Date, and subsequent
payments to the Relators will be made within 21 days after each additional
payment is received by the United States, by wire transfer to each of the
Relators in accordance with instructions to be provided by Relators' counsel.
Jay A. Buford, William L. Schoff, and Russell Davis, for themselves
individually, and for their respective heirs, successors, and assigns, will
release and will be deemed to have released and forever discharged the United
States from any claims pursuant to 31 U.S.C. (S) 3730, including 31 U.S.C.
(S)(S) 3730(b), (c), (d) and (d)(1), for a share of the proceeds of the Civil
Action, from any claims for a share of


the Settlement Amount, and from any claims arising from the filing of their
Civil Action, and in full settlement of claims under this Agreement. This
Agreement does not resolve or in any manner affect any claims the United States
has or may have against the Relators Jay A. Buford, William L. Schoff, or
Russell L. Davis arising under Title 26, U.S. Code (Internal Revenue Code), or
any claims arising under this Agreement.

     18.  After this Agreement is fully executed, the United States and the
Relators will notify the Court that all pertinent Parties have stipulated that,
to the extent alleged in Paragraphs K through Y only, the Civil Action shall be
dismissed with prejudice effective upon receipt by the United States and the
Participating States of the payments described in Paragraph 1 above, pursuant to
and consistent with the terms of this Agreement.   The United States will notify
the Court that it declines to intervene in the remaining claims by the Relators
in the Civil Action, to the extent not alleged in Preamble Paragraphs K through
Y, and that the Relators intend to proceed on those claims.  The Parties agree
that the United States District Court for the District of Massachusetts shall
maintain jurisdiction of the unresolved claims in the Civil Action, all claims
in the Civil Action in the event that the Plea Agreements referenced in Preamble
Paragraphs C and D are not accepted by the Court, in an Event of Default, in the
event of disputes under this Agreement, and for purposes of resolving any
disputes regarding the Relators' claim against LIFECHEM, MPD, and the NMC
Companies for reasonable attorneys' fees, expenses and costs pursuant to 31
U.S.C. (S) 3730(d), arising from the filing of the Civil Action.

     19.  LIFECHEM, MPD, and the NMC Companies waive and will not assert any
defenses these entities may have to any criminal prosecution or administrative
action relating to the conduct described in Preamble Paragraphs K through Y,
which defenses may be based in whole or in part on a contention that, under the
Double Jeopardy Clause of the Fifth Amendment of the Constitution or Excessive
Fines Clause of the Eighth Amendment of the Constitution, this


Settlement Agreement bars a remedy sought in such criminal prosecution or
administrative action. LIFECHEM, MPD, and the NMC Companies further agree that
nothing in this Agreement is punitive in purpose or effect.

     20.  Effective on the date of acceptance by the Court of the Plea
Agreements referenced in Preamble Paragraphs C and D, LIFECHEM, MPD, and the NMC
Companies release and will be deemed to have released the United States, its
agencies, employees, servants, and agents from any claims (including attorneys
fees, costs, and expenses of every kind and however denominated) which LIFECHEM,
MPD, and the NMC Companies have or may have against the United States, its
agencies, employees, servants, and agents, related to or arising from the United
States' civil, criminal and administrative investigation and prosecution of
LIFECHEM, MPD, NMC and FMCH.

     21.  The Settlement Amount that NMC and FMCH must pay pursuant to this
Agreement by electronic wire transfer pursuant to Paragraph 1 above will not be
decreased as a result of the denial of claims for payment now being withheld
from payment by any Medicare carrier or intermediary, Railroad Retirement
Medicare carrier, TRICARE, FEHBP, VA, or any Medicaid payer, related to the
conduct described in Preamble Paragraphs K through Y; and LIFECHEM, MPD and the
NMC Companies agree not to resubmit to any Medicare carrier or intermediary,
Railroad Retirement Medicare carrier, TRICARE, FEHBP, VA, or any Medicaid payer
any previously denied claims related to the conduct described in Preamble
Paragraphs K through Y, and agree not to appeal any such denials of claims.

     22.  The NMC Companies agree that all costs (as defined in the Federal
Acquisition Regulations ("FAR") (S) 31.205-47 and in Titles XVIII and XIX of the
Social Security Act, 42 U.S.C. (S)(S) 1395-1395ddd (1997) and 1396-1396v(1997),
and the regulations promulgated thereunder) incurred by or on behalf of
LIFECHEM, MPD, and the NMC Companies, and their divisions, subsidiaries and
affiliates, and their present and former officers, directors, employees,


shareholders and agents in connection with:  (a) the matters covered by this
Agreement and the related Plea Agreements described in Preamble Paragraphs C and
D; (b) the Government's administrative, civil and criminal investigation and
prosecution of LIFECHEM, MPD, NMC, and FMCH; (c) these corporate entities'
investigation, defense, and corrective actions undertaken in response to the
Government's administrative, civil and criminal investigations, and  in
connection with the matters covered by this Agreement, the Plea Agreements, and
including the obligations undertaken pursuant to the Corporate Integrity
Agreement (including attorneys fees); (d) the negotiation and performance of
this Agreement, the Plea Agreements, and the Corporate Integrity Agreement; and
(e) the payments made to the United States provided for in this Agreement and
the Plea Agreements, and to Relators for attorney's fees and costs, are
unallowable costs on Government contracts and under Medicare, Railroad
Retirement Medicare, Medicaid, TRICARE, FEHBP, and the VA programs (hereafter,
"unallowable costs"). These unallowable costs will be separately estimated and
accounted for by LIFECHEM, MPD, and the NMC Companies and these entities will
not charge such unallowable costs directly or indirectly to any contracts with
the United States or any Medicaid program, or seek payment for such unallowable
costs through any cost report, cost statement, information statement or payment
request submitted by the NMC Companies or any of their divisions, subsidiaries
or affiliates to the Medicare, Railroad Retirement Medicare, Medicaid, TRICARE,
VA or FEHBP programs.

     LIFECHEM, MPD, and the NMC Companies further agree that within 270 days of
the effective date of this Agreement these entities will identify to applicable
Medicare, Railroad Retirement Medicare, and TRICARE fiscal intermediaries,
carriers and/or contractors, and Medicaid, VA and FEHBP fiscal agents, any
unallowable costs (as defined above) included in payments previously sought from
the United States, or any Medicaid Program, including, but not limited to,
payments sought in any cost reports, cost statements, information reports, or
payment requests already submitted by the NMC Companies or any of their
subsidiaries, affiliates, or


divisions and will request, and agree, that such cost reports, cost statements,
information reports or payment requests, even if already settled, be adjusted to
account for the effect of the inclusion of the unallowable costs. LIFECHEM, MPD,
and the NMC Companies agree that the United States will be entitled to recoup
from the NMC Companies any overpayment as a result of the inclusion of such
unallowable costs on previously-submitted cost reports, information reports,
cost statements or requests for payment. Any payments due after the adjustments
have been made shall be paid to the United States pursuant to the direction of
the Department of Justice, and/or the affected agencies. The United States
reserves its rights to disagree with any calculations submitted by LIFECHEM,
MPD, the NMC Companies, or any of their subsidiaries, affiliates or divisions,
on the effect of inclusion of unallowable costs (as defined above) on the NMC
Companies or any of their subsidiaries, affiliates or divisions' cost reports,
cost statements or information reports. Nothing in this Agreement shall
constitute a waiver of the rights of the United States to examine or reexamine
the unallowable costs described above.

     23.  This Agreement is intended to be for the benefit of the Parties only,
and by this instrument the Parties do not release any claims against any other
person or entity except as specifically identified in Paragraph 9, 13, 14, 15,
and 17 above.

     24.  LIFECHEM, MPD and the NMC Companies agree that they will not seek
payment for any of the health care billings covered by this Agreement from any
health care beneficiaries or their parents, sponsors, estates, heirs, successors
or assigns.  LIFECHEM, MPD and the NMC Companies waive any causes of action
against these beneficiaries or their parents, sponsors, estates, heirs,
successors, or assigns based upon the claims for payment covered by this
Agreement.

     25.  The NMC Companies covenant to cooperate fully and truthfully with the
United States' civil investigation of individuals not specifically released in
this Agreement.  The NMC Companies will make reasonable efforts to facilitate
access to, and encourage the cooperation of,


its directors, officers and employees for interviews and testimony, consistent
with the rights and privileges of such individuals, and will furnish to the
Untied States, upon reasonable request, all non-privileged documents and records
in its possession, custody or control.

     26.  Nothing in this Agreement constitutes an agreement by the United
States concerning the characterization of the amounts paid hereunder for
purposes of any proceeding under Title 26 of the Internal Revenue Code.

     27.  Except as provided in Paragraph 6.b., and except for Relators'
unresolved claim against LIFECHEM, MPD, and the NMC Companies for reasonable
attorneys' fees, expenses and costs pursuant to 31 U.S.C. (S) 3730(d), each
party to this Agreement will bear his or its own legal and other costs incurred
in connection with this matter, including by way of example only, all costs
incurred in the investigation and defense of this matter, the preparation and
performance of this Agreement, and all corrective actions taken in response to
the investigation and resolution of this matter.

     28.  NMC and FMCH expressly warrant that they have reviewed their financial
condition and that they currently are solvent on a consolidated basis within the
meaning of 11 U.S.C. Section 547(b)(3), and expect to remain solvent on a
consolidated basis following payment to the United States hereunder.  Further,
the Parties expressly warrant that, in evaluating whether to execute this
Agreement, the Parties (a) have intended that the mutual promises, covenants and
obligations set forth herein constitute a contemporaneous exchange for new value
given to LIFECHEM, MPD, NMC and FMCH within the meaning of 11 U.S.C. Section
547(c)(1), and (b) have concluded that these mutual promises, covenants, and
obligations do, in fact, constitute such a contemporaneous exchange.

     29.  In the event NMC or FMCH commences, or a thirty party commences,
within 91 days of any payment under of this Agreement, any case, proceeding, or
other action (i) under any law relating to bankruptcy, insolvency,
reorganization or relief of debtors, seeking to have any


order for relief of NMC and/or FMCH's debts, or seeking to adjudicate NMC and/or
FMCH as bankrupt or insolvent, or (ii) seeking appointment of a receiver,
trustee, custodian or other similar official for NMC and/or FMCH or for all or
any substantial part of NMC and/or FMCH's assets, NMC and FMCH agree as follows:

          a.   NMC and FMCH's obligations under this Agreement may not be
avoided pursuant to 11 U.S.C. Section 547, and NMC and FMCH will not argue or
otherwise take the position in any such case, proceeding or action that: (i) NMC
and/or FMCH's obligations under this Agreement may be avoided under 11 U.S.C.
Section 547; (ii) NMC and FMCH were insolvent on a consolidated basis at the
time this Agreement was entered into, or became insolvent on a consolidated
basis as a result of the payment made to the United States hereunder; or (iii)
the mutual promises, covenants and obligations set forth in this Agreement do
not constitute a contemporaneous exchange for new value given to NMC and/or
FMCH.

          b.   In the event that NMC and/or FMCH's obligations hereunder are
avoided pursuant to 11 U.S.C. Section 547, the United States, at its sole
option, may rescind the releases in this Agreement, and bring any civil and/or
administrative claim, action or proceeding against LIFECHEM, MPD, NMC, and/or
FMCH for the claims that would otherwise be covered by the releases provided in
Paragraph 9, 13, 14 and 15 above. If the United States chooses to do so,
LIFECHEM, MPD, NMC and FMCH agree that (i) any such claims, actions or
proceedings brought by the United States (including any proceedings to exclude
LIFECHEM and/or MPD from participation in Medicare, Medicaid, or other federal
health care programs) are not subject to an "automatic stay" pursuant to 11
U.S.C. Section 362(a) as a result of the action, case or proceeding described in
the first clause of this Paragraph, and that LIFECHEM, MPD, NMC and FMCH will
not argue or otherwise contend that the United States' claims, actions or
proceedings are subject to an automatic stay; (ii) that LIFECHEM, MPD, NMC and
FMCH will not plead, argue or otherwise raise any defenses under the theories of
statute of limitations, laches, estoppel


or similar theories, to any such civil or administrative claims, actions or
proceeding which are brought by the United States within 90 calendar days of
written notification to NMC and FMCH that the releases herein have been
rescinded pursuant to this Paragraph, except to the extent such defenses were
available on December 15, 1994; and (iii) the United States has a valid claim
against NMC and FMCH in the amount of the Default Obligation, and the United
States may pursue its claim, inter alia, in the case, action or proceeding
referenced in the first clause of this Paragraph, as well as in any other case,
action, or proceeding.

          c.   LIFECHEM, MPD, NMC and FMCH acknowledge that its agreements in
this Paragraph are provided in exchange for valuable consideration provided in
this Agreement.

     30.  LIFECHEM, MPD, NMC, FMCH, and each of the Relators represent that this
Agreement is freely and voluntarily entered into without any degree of duress or
compulsion whatsoever.

     31.  This Agreement is governed by the laws of the United States.  The
Parties agree that the exclusive jurisdiction and venue for any disputes arising
between and among the Parties under this Agreement will be the United States
District Court for the District of Massachusetts, except that disputes rising
under the Corporate Integrity Agreement shall be resolved exclusively upon the
dispute resolution provisions set forth in the Corporate Integrity Agreement.

     32.  The undersigned LIFECHEM, MPD, NMC and FMCH signatories represent and
warrant that they are authorized by their respective Board of Directors to
execute this Agreement.  The undersigned United States signatories represent
that they are signing this Agreement in their respective official capacities and
that they are authorized to execute this Agreement.

     33.  Except for the guilty pleas by LIFECHEM and MPD, and the
representations in Paragraphs 28 (regarding solvency), and Paragraph 29
(concerning bankruptcy proceedings commenced within 91 days of any payments
under this Agreement), the Parties agree that




nothing in this Agreement constitutes an admission by any person or entity with
respect to any issue of law or fact.

     34.  This Agreement is effective on the date of signature of the last
signatory to the Agreement (the "Effective Date").

     35.  This Agreement shall be binding on all successors, transferees, heirs
and assigns.

     36.  This Agreement, together with attachments A through D, the Plea
Agreements described in Preamble Paragraphs C and D, and the Corporate Integrity
Agreement, constitute the complete agreement among the Parties with regard to
the conduct described in Preamble Paragraphs K through Y. This Agreement may not
be amended except by written consent of the Parties, except that only FMCH and
OIG-HHS must agree in writing to modification of the Corporate Integrity
Agreement.

     37.  This Agreement may be executed in counterparts, each of which shall
constitute an original and all of which shall constitute one and the same
Agreement.

                                PROMISSORY NOTE
                                ---------------

AMOUNT: $371,549,253                                    Lexington, Massachusetts
                                                        January 19, 2000

     FOR VALUE RECEIVED the undersigned, Fresenius Medical Care Holdings, Inc.
and National Medical Care, Inc., which will be referred to as "Makers", hereby
jointly and severally promise to pay the principal sum of three hundred seventy
one million five hundred forty nine thousand two hundred fifty three dollars
($371,549,253.00) to the United States ("Payee"), in lawful money of the United
States according to the terms set forth below. This principal sum represents the
"Settlement Amount(s)," to the extent not already paid to Payees by Makers, as
defined in the four civil Settlement Agreements entered into between Makers and
others and the United States on January 19, 2000 (the "Effective Date").

          Said principal sum shall be paid as follows:

     1.   Makers agree jointly and severally to pay to the United States to
resolve civil liabilities, the sum of three hundred seventy one million five
hundred forty nine thousand two hundred fifty three dollars ($371,549,253.00),
and this sum shall constitute a debt immediately due and owing to the United
States on the "First Payment Date," which is the later of the dates on which (a)
the four civil Settlement Agreements are fully executed by the Parties, (b) all
notices of dismissal described in the civil Settlement Agreements are docketed
by the Court, or (c) the Court accepts LIFECHEM, INC.'s, NMC Medical Products,
Inc.'s, and NMC Homecare, Inc.'s guilty pleas and imposes the sentences set
forth in their respective Plea Agreements, on the following terms and
conditions, as further allocated among the four civil Settlement Agreements as
set forth on Attachment A:

          A.   On the First Payment Date, Makers shall pay to the United States
               the principal amount of $236,401,919, plus interest in an amount
               of $48,576 for each day from January 20, 2000 through April 15,
               2000, when the interest amount will increase by an additional
               amount of $7,271 for each day, for each quarterly payment due
               before this first payment is due;

          B.   On April 14, 2000, Makers shall pay the principal amount of
               $32,851,287 and the interest amount of $2,534,013 to the United
               States;

          C.   On July 14, 2000, Makers shall pay the principal amount of
               $33,467,249 and the interest amount of $1,918,051 to the United
               States;

          D.   On October 16, 2000, Makers shall pay the principal amount of
               $34,094,760 and the interest amount of $1,290,540 to the United
               States;

          E.   On January 15, 2001, Makers shall pay the principal amount of
               $34,734,037 and the interest amount of $651,263 to the United
               States.

The payments to the United States described above shall be electronically
transferred by noon

                                       1


(Boston, Massachusetts time) on the date the payment is due pursuant to
instructions provided by the United States Attorney's Office for the District of
Massachusetts.

     2.   On January 19, 2000, Makers shall establish an escrow account in an
initial amount of $236,401,919, to be held by an independent third party
agreeable to the United States, and Makers shall increase the escrow amount each
day in an amount of $48,546 (through accrued interest and/or deposits),
beginning on January 20, 2000 and continuing through April 15, 2000, when Makers
shall increase the escrow amount by an additional amount each day of $7,271
(through accrued interest and/or deposits), for each quarterly payment due
before the first payment is due on the First Payment Date. On the First Payment
Date, all funds in the escrow account shall be paid to the United States to
satisfy the payment obligation in Paragraph 1.A. The terms and conditions of
this escrow account shall in no way limit the Makers' payment obligations to the
United States pursuant to this Promissory Note.

     3.   There will be no penalty for prepayment of the amounts in Paragraph 1.
All prepayments, if any, shall be applied first to accrued interest on the
Settlement Amount, with any remainder to be applied to unpaid principal. Makers
shall provide a written prepayment notice delivered to the United States
Attorney's Office for the District of Massachusetts one week prior to
prepayment.

     4.   Makers shall procure from the Bank of Nova Scotia and deliver or cause
to be delivered to the United States Attorney's Office for the District of
Massachusetts, on or before January 19, 2000, an amendment to the unconditional,
irrevocable Letter of Credit No. S020/43695/96 issued to the United States of
America on September 27, 1996 (the "Letter of Credit") to increase the amount of
the Letter of Credit to $189,634,446.00. Such amendment shall be in the form
attached as Attachment B. Within 10 days of receipt by the U.S. Attorney's
Office of written confirmation from the transferring bank that a quarterly
payment, as described in Paragraphs 1.B. through 1.E. above, or prepayment of
such quarterly payments, has been made to the United States, the United States
shall provide written permission to the Bank of Nova Scotia to reduce the amount
available for drawing under Letter of Credit No. S020/43695/96 by the amount of
the principal payment received. In the event that the entire outstanding payment
obligation secured by the Letter of Credit is prepaid, then the United States
shall provide written permission to reduce the amount available for drawing to
zero. The United States shall return this Letter of Credit for cancellation when
all obligations secured by it are paid in full or it is determined, by the
United States, or pursuant to a final and non-appealable order of a court of
competent jurisdiction, that Makers have fulfilled all such payment obligations.

     5.   Makers are in default of this Promissory Note on the date of
occurrence of any of the following events ("Events of Default"):

          a.   Makers' failure to procure, deliver or maintain the Letter
               of Credit;

          b.   Makers' failure to pay any amount provided for in this Promissory
               Note within two days of when such payment is due and payable;

          c.   If prior to making the full payment of the amount due under this
               Promissory Note:

               (i)  NMC and/or FMCH commences any case, proceeding, or other

                                       2


                     action

                     (A) under any law relating to bankruptcy, insolvency,
                     reorganization or relief of debtors, seeking to have any
                     order for relief of debtors, or seeking to adjudicate NMC
                     and/or FMCH as bankrupt or insolvent, or

                     (B) seeking appointment of a receiver, trustee, custodian
                     or other similar official for NMC and/or FMCH or for all or
                     any substantial part of NMC's and/or FMCH's assets; or

               (ii)  there shall be commenced against NMC and/or FMCH any such
                     case, proceeding or other action referred to in clause (i)
                     which results in the entry of an order for relief and any
                     such order remains undismissed, or undischarged or unbonded
                     for a period of thirty (30) days; or

               (iii) NMC and/or FMCH takes any action authorizing, or in
                     furtherance of, or indicating its consent to, approval of,
                     or acquiescence in, any of the acts set forth above in sub-
                     Paragraph 5.c.(ii); or

          d.   Makers' failure to establish, maintain, or make the required
               payments to the escrow account described in Paragraph 2.

     6.   If payments due under Paragraph 1 are received late, but within the
two-day grace period provided in Paragraph 5.b., interest incurred during such
grace period will be assessed at two times the daily amount in effect on the
date the payment was due.

     7.   Makers shall provide the United States written notice of an Event of
Default within two (2) business days of such event by overnight mail, or
facsimile followed by overnight delivery, to the United States Attorney's
Office, District of Massachusetts, One Courthouse Way, Suite 9200, Boston, MA
02210.

     8.   Immediately upon the occurrence of an Event of Default, without
further notice or presentment and demand by the United States:

          a.             The Settlement Amount plus accrued interest through the
               end of the applicable quarter as set forth in Paragraph 1 (minus
               any payments to date of principal and accrued interest) shall
               become immediately due and payable ("Settlement Default Amount").
               Interest shall be calculated on the Settlement Default Amount at
               the Prime Rate as published in the Wall Street Journal on the
                                                  -------------------
               Effective Date of this Promissory Note plus 5% from the date of
               the Event of Default.

          a.             In addition, Makers will pay the United States all
               reasonable costs of collection and enforcement of this Promissory
               Note, including attorneys' fees and expenses, plus interest as
               described in Paragraph 8.a. The Settlement Default Amount, plus
               interest, described in

                                       3


               Paragraph 8.a., together with the costs of collection and
               enforcement described in this sub-paragraph, will be referred to
               as the "Default Obligation."

     9.   Upon the occurrence of an Event of Default, the United States may
exercise, at its sole option, one or more of the following rights:

          a.             The United States may draw the full amount available
               for drawing under the Letter of Credit and retain all proceeds
               thereof.

          b.             The United States may enforce the terms of the
               Guarantee Agreement between the United States of America,
               Fresenius Medical Care GMBH, a German corporation and the
               predecessor of Fresenius Medical Care AG, W.R. Grace & Co., a New
               York corporation, and National Medical Care, Inc., dated July 31,
               1996.

          c.             The United States retains any and all other rights and
               remedies it has or may have under law and equity.

          d.             No failure or delay on the part of the United States to
               exercise any right or remedy shall operate as a waiver of the
               United States' rights. No single or partial exercise by the
               United States of any right or remedy shall operate as a waiver of
               the United States' rights.

     10.  This Promissory Note shall be binding upon Makers, their successors
and assigns, and shall inure to the benefit of the Payee, its successors and
assigns. This Promissory Note shall be governed and construed according to the
laws of the United States of America.

     11.  Makers acknowledge that they are entering into this agreement freely,
voluntarily and with no degree of compulsion whatsoever.

     12.  Makers shall provide to the United States Attorney for the District of
Massachusetts a certified copy of a resolution of their respective Board of
Directors affirming that each of their Board of Directors has authority to enter
into this Promissory Note, and has (1)

                                       4

Settlement Agreements entered into between Makers, the United States, and others
on January 19, 2000; (2) consulted with legal counsel in connection with the
matter; (3) voted to enter into this Promissory Note; and (4) voted to authorize
the corporate officer identified below to execute this Promissory Note and to
take such further steps as necessary to carry out the terms of this Promissory
Note.

     13.  When the indebtedness represented by this Note is satisfied, the
United States will return a copy of the note to Makers, through counsel, marked
"paid in full" and endorsed by an authorized representative of the United
States.

     IN WITNESS WHEREOF, Makers intending to be legally bound hereby and to so
bind their successors and assigns, have caused this Note to be executed by its
proper corporate officers and their corporate seals hereunto affixed, duly
attested, the day and year first above written.
