                              SETTLEMENT AGREEMENT

                                   I. PARTIES

         This Settlement Agreement ("Agreement") is entered into between the
United States of America, acting through the United States Department of Justice
and on behalf of the Office of Inspector General ("OIG-HHS") of the Department
of Health and Human Services ("HHS"), and TRICARE Management Activity ("TMA")
through its General Counsel (collectively the "United States"); the States of
Illinois, New Mexico, South Carolina, Tennessee, Texas, and West Virginia
(collectively the "participating States"); and Community Health Systems, Inc.
("CHS"). Collectively, all of the above will be referred to as "the Parties."

                                  II. PREAMBLE

         As a preamble to this Agreement, the Parties agree to the following:

         A. CHS is a health care provider that owns and operates hospitals, and
submitted or caused to be submitted, claims to Medicare, Medicaid, and TRICARE
for the inpatient treatment of Medicare, Medicaid, and TRICARE beneficiaries.

         B. CHS submitted or caused to be submitted claims for payment to the
Medicare Program ("Medicare"), Title XVIII of the Social Security Act, 42 U.S.C.
ss.ss. 1395-1395ggg(1999); the Medicaid Program, 42 U.S.C. ss.ss. 1396-1396v
(1997); and the TRICARE program (formerly known as the Civilian Health and
Medical Program of the Uniformed Services (CHAMPUS)), 10 U.S.C. ss.ss.
1071-1106.

         C. The Medicare, participating States' Medicaid, and TRICARE programs
make payments to a hospital for inpatient treatment rendered to a beneficiary
generally based upon the beneficiary's "principal diagnosis," as set forth by
the hospital.

         D. The Medicare, participating States' Medicaid, and TRICARE programs
rely upon participating hospitals to properly indicate the principal diagnosis
through the use of standard diagnosis codes.
<PAGE>

         E. In December 1997, CHS contacted the OIG-HHS and disclosed possible
coding problems at CHS.

         F. CHS engaged in discussions with OIG-HHS to develop procedures for
CHS to perform a self-audit of inpatient payment claims submitted by CHS to the
Medicare program that grouped to the following DRGs: 014, 079, 087, 132, 138,
296, 416, and 475 (the "covered DRGs"). CHS then undertook the self-audit and
extrapolated the findings.

         G. CHS provided the results of its self-audit and extrapolations
relating to the covered DRGs to the United States, and the United States has
reviewed these results.

         H. The United States and the participating States (as to Medicaid)
conducted an investigation into inpatient payment claims submitted to Medicare,
Medicaid, and TRICARE by CHS hospitals that grouped to the covered DRGs.

         I. The United States contends that it has certain civil claims against
CHS under the False Claims Act, 31 U.S.C. ss.ss. 3729-3733, and other federal
statutes and/or common law doctrines as more specifically identified in
Paragraph 5 below, for engaging in the following alleged conduct: the CHS
hospitals listed on Attachment A, for the time periods described in Attachment
A, submitted or caused to be submitted to Medicare, Medicaid, and TRICARE claims
for certain ICD-9-CM diagnosis codes for inpatient admissions grouping to the
covered DRGs that were not supported by the patients' medical records and as a
consequence received greater reimbursement than that to which the hospitals were
otherwise entitled for those admissions (hereinafter referred to as the "Covered
Conduct"). The Covered Conduct refers only to those hospitals listed in
Attachment A for the time periods described therein.

         J. The United States also contends that it has certain administrative
claims against CHS under the provisions for permissive exclusion from Medicare,
Medicaid and other federal health care programs, 42 U.S.C. ss. 1320a-7(b), and
the provisions for civil monetary penalties, 42 U.S.C. ss. 1320a-7a, for the
Covered Conduct.


                                     - 2 -
<PAGE>

         K. The participating States also contend that they have certain claims
against CHS under their respective laws for claims to the Medicaid program
concerning the Covered Conduct.

         L. CHS has provided documents and information to the United States in
response to the government's investigation of the Covered Conduct, and CHS
represents that such response has been truthful, accurate, and complete to the
best of its knowledge and ability.

         M. This Settlement Agreement is made in compromise of disputed claims.
Neither this Settlement Agreement nor any action taken pursuant to this
Agreement shall constitute an admission of wrongdoing or fault of any kind on
the part of CHS.

         N. CHS does not admit the contentions of the United States or the
participating States as set forth above.

         O. To avoid the delay, uncertainty, inconvenience and expense of
protracted litigation of these claims, the Parties reach a full and final
settlement as set forth below.

                            III. TERMS AND CONDITIONS

         NOW, THEREFORE, in consideration of the mutual promises, covenants, and
obligations set forth below, and for good and valuable consideration as stated
herein, the Parties agree as follows:

         1. CHS agrees to pay to the United States $30,494,749.51 plus interest
as follows: CHS agrees to make payment by electronic funds transfer pursuant to
written instructions to be provided by the Commercial Litigation Branch, Civil
Division, Department of Justice. CHS agrees to make this electronic funds
transfer no later than ten (10) business days after the date that the United
States hand-delivers to the District of Columbia offices of Fried, Frank,
Harris, Shriver & Jacobson, as counsel to CHS, a copy of the fully-executed
Agreement. CHS agrees to pay an additional amount of $409,876.05 plus interest
representing recovery for the participating States' share of Medicaid; such
payment shall be made no later than ten (10) business days after the date that
the United States hand-delivers to the District of Columbia offices of Fried,
Frank,


                                     - 3 -
<PAGE>

Harris, Shriver & Jacobson, as counsel to CHS, a copy of the fully-executed
Agreement and pursuant to written instructions provided by the National
Association of Medicaid Fraud Control Units. Interest shall be at the
post-judgment interest rate (as set forth in 28 U.S.C. ss. 1961(a)) in effect as
of February 3, 2000, and shall be computed from December 1, 1999 through the
date of payment under this Paragraph. The payment to the United States and to
the participating States together, including interest, constitutes the
"Settlement Amount."

         2. CHS agrees to cooperate fully and in good faith with the United
States in the administrative, civil or criminal investigation or prosecution of
any person concerning the Covered Conduct, and concerning similar matters
involving other hospitals and others, by providing accurate, truthful, and
complete information whenever, wherever, to whomever and in whatever form the
United States reasonably may request. Upon reasonable notice, CHS 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
United States, upon reasonable request, all non-privileged documents and records
in its possession, custody or control relating to the Covered Conduct. Nothing
in this Paragraph, however, affects any privilege that might be available to CHS
or any regulatory or statutory obligation of CHS, or CHS's ability to object to
the request on the grounds of such privilege or obligation; the United States
reserves its right to contest the assertion of any such privilege or obligation
by CHS.

         3. CHS has entered into a Corporate Compliance Agreement with OIG-HHS,
attached as Attachment B, which is incorporated into this Agreement by
reference. CHS will implement its obligations under the Corporate Compliance
Agreement as set forth in the Corporate Compliance Agreement.

         4. CHS releases the United States, HHS, TRICARE, the participating
States and each of their agencies, officers, agents, employees, and contractors
and their employees, from any and all claims, causes of action, adjustments, and
set-offs of any


                                     - 4 -
<PAGE>

kind arising out of or pertaining to the Covered Conduct, including the
investigation of the Covered Conduct and this Agreement.

         5. Subject to the exceptions in Paragraphs 10 and 15 below, in
consideration of the obligations of CHS set forth in this Agreement, conditioned
upon CHS's payment in full of the Settlement Amount, the United States (on
behalf of itself, its officers, agents, and its agencies and departments
referenced above in Paragraph 4), agrees to release CHS, its predecessors,
successors, assigns, and affiliates and those hospitals listed in Attachment A
(collectively, "the Released Parties") from any civil or administrative monetary
claim the United States has or may have for the Covered Conduct for the time
period specified for each facility listed in Attachment A under the False Claims
Act, 31 U.S.C. ss.ss. 3729-3733; the Civil Monetary Penalties Law, 42 U.S.C. ss.
1320a-7a; the Program Fraud Civil Remedies Act, 31 U.S.C. ss.ss. 3801-3812; or
the common law theories of payment by mistake, unjust enrichment, breach of
contract and fraud. The United States expressly reserves any claims against any
entities and individuals other than claims against the Released Parties for the
Covered Conduct.

         6. Subject to the exceptions in Paragraphs 10 and 15 below, in
consideration of the obligations of CHS set forth in this Agreement, conditioned
upon CHS's payment in full of the Settlement Amount, the participating States
(on behalf of themselves, their officers, agents, and their agencies and
departments) agree to release the Released Parties from any civil or
administrative monetary claim the participating States have or may have under
State law for the time period specified for each facility listed in Attachment A
for the Covered Conduct, including any claim under a state false claims or
whistleblower law or any other common law, statutory or administrative theory.
The participating States expressly reserve any claims against any entities and
individuals other than claims against the Released Parties for the Covered
Conduct.

         7. In consideration of the obligations of CHS set forth in this
Agreement, including the Corporate Compliance Agreement at Attachment B, and
conditioned upon CHS's payment in full of the Settlement Amount, the OIG-HHS
agrees to release and


                                     - 5 -
<PAGE>

refrain from instituting, directing or maintaining any administrative claim or
any action seeking exclusion from Medicare, Medicaid or other federal health
care programs (as defined in 42 U.S.C. ss. 1320a-7b(f)) against the Released
Parties under 42 U.S.C. ss. 1320a-7a (Civil Monetary Penalties Law), or 42
U.S.C. ss. 1320a-7(b) (permissive exclusion), for the time period specified for
each facility listed in Attachment A for the Covered Conduct, except as reserved
in this Paragraph. The OIG-HHS expressly reserves all rights to comply with any
statutory obligations to exclude CHS or others from Medicare, Medicaid or other
federal health care programs under 42 U.S.C. ss. 1320a-7(a) (mandatory
exclusion). Nothing in this Paragraph precludes the OIG-HHS from taking action
against entities or persons, or for conduct and practices, for which civil
claims have been reserved in Paragraph 10 or 15, below. The OIG-HHS expressly
reserves any claims against any entities and individuals other than the Released
Parties for the Covered Conduct.

         8. In consideration of the obligations of CHS set forth in this
Agreement, and conditioned upon CHS's payment in full of the Settlement Amount,
the TMA agrees to release and refrain from instituting, directing, or
maintaining any administrative claim or any action seeking exclusion from the
TRICARE Program against CHS under 32 C.F.R. ss. 199.9 for the time period
specified for each facility listed in Attachment A for the Covered Conduct,
except as reserved in Paragraph 10 or 15 below. The TMA expressly reserves
authority to exclude CHS from the TRICARE program under 32 C.F.R. H 199.9
(f)(1)(i)(A), (f)(1)(i)(B), (f)(1)(i)(D), and (f)(1)(iii), based upon the
Covered Conduct. Nothing in this Paragraph precludes the TRICARE program from
taking action against entities or persons, or for conduct and practices, for
which civil claims have been reserved in Paragraph 10 or 15, below. The TMA
expressly reserves any claims against any entities and individuals other than
the Released Parties for the Covered Conduct.

         9. The participating States recognize that this Agreement is intended
to allow CHS to continue to participate in the Medicaid program and is intended
as a bar to any action initiated by the participating States to impose Medicaid
program exclusion upon


                                     - 6 -
<PAGE>

CHS on the basis of the Covered Conduct for the time period specified for each
facility listed in Attachment A, except as reserved in Paragraph 10 or 15 below.
The Parties recognize, however, that participation in the Tennessee
Medicaid/TennCare program is dependent upon acceptance into a network by a
Managed Care Organization ("MCO") and that MCOs have discretion, so long as
consistent with federal and state law, to set policies for participation in
their networks. The Office of the Tennessee Attorney General will not attempt to
influence any MCO to exclude CHS from participation in an MCO network due to the
Covered Conduct. The State of Tennessee states that it does not have the
authority to release CHS from any claims or actions for debarment or otherwise
which may be asserted by private insurers or similar entities such as MCOs and
Behavioral Health Organizations that are paid on a capitated basis for providing
health care to the State's Medicaid/TennCare recipients. However, Department of
Health, TennCare Bureau will not exclude CHS from participation in the
Medicaid/TennCare program based upon the Covered Conduct unless required to do
so by the United States Department of Health and Human Services.

         10. Notwithstanding any term of this Agreement, specifically reserved
and excluded from the scope and terms of this Agreement as to any entity or
person (including the Released Parties) are any and all of the following:

                  (a) Any civil, criminal or administrative claims arising under
Title 26, U.S. Code (Internal Revenue Code) or any state revenue laws;

                  (b) Any criminal liability;

                  (c) Except as explicitly otherwise stated in this Agreement,
any administrative liability, including mandatory exclusion from federal health
care programs;

                  (d) Any liability to the United States (or its agencies) for
any conduct other than the Covered Conduct;

                  (e) Any claims based upon such obligations as are created by
this Agreement;


                                     - 7 -
<PAGE>

                  (f) Any express or implied warranty claims or other claims for
defective or deficient products or services, including quality of goods and
services, provided by CHS;

                  (g) Any claims based on a failure to deliver items or services
billed;

                  (h) Any claims against any individuals, including officers and
employees; however, if such individuals are legally entitled to repayment from
CHS, by claim for indemnification, contribution, reimbursement or otherwise as a
result of a claim brought by the United States or any other party to this
Agreement for the Covered Conduct, the releases provided in Paragraphs 5 and 6
above shall apply to such individuals with respect to that claim;

                  (i) Claims under any consumer protection Acts or regulations,
licensing, certificate of need or similar state regulatory proceedings other
than Medicaid recoupment of the participating States; and

                  (j) Claims asserted in UNITED STATES EX REL. SMITH v.
COMMUNITY HEALTH SYSTEMS, INC., Civil Action No. 3-99 0869 (M.D. Tenn.); UNITED
STATES EX REL. BLEDSOE v. COMMUNITY HEALTH SYSTEMS, INC., Civil Action No.
1:98-cv-0435-MHS (N.D. Ga.); and the sealed matter identified in the letter
dated March 28, 2000 from the United States Department of Justice, Civil
Division, to Fried, Frank, Harris, Shriver & Jacobson as attorneys for CHS.

         11. CHS waives and will not assert any defenses it may have to any
criminal prosecution or administrative action relating to the Covered Conduct,
which defenses may be based in whole or in part on a contention that, under the
Double Jeopardy or Excessive Fines Clause of the Constitution, this settlement
bars a remedy sought in such criminal prosecution or administrative action. CHS
agrees that this settlement is not punitive in purpose or effect. Nothing in
this Paragraph or any other provision of this Agreement constitutes an agreement
by the United States concerning the characterization of the Settlement Amount
for purposes of the Internal Revenue Laws, Title 26 of the United States Code or
state tax or revenue laws.


                                     - 8 -
<PAGE>

         12. The Settlement Amount that CHS 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, TRICARE or any State payer (including
state Medicaid Managed Care Organizations ("MCO")), related to the Covered
Conduct or the self audit; and CHS agrees not to resubmit to any Medicare
carrier or intermediary, TRICARE or any State payer or MCO any previously denied
claims related to the Covered Conduct or the self audit, and agrees not to
appeal any such denials of claims.

         13. CHS agrees that all costs (as defined in the Federal Acquisition
Regulations ("FAR") ss. 31.205-47 and in Titles XVIII and XIX of the Social
Security Act, 42 U.S.C. ss.ss. 1395-1395ggg (1999) and 1396-1396v(1997), and the
regulations promulgated thereunder) incurred by or on behalf of CHS or any of
its subsidiaries in connection with: (a) the matters covered by this Agreement,
(b) the Government's audit(s) and civil and any criminal investigation(s) of the
matters covered by this Agreement, (c) CHS's investigation, self audit, defense,
and corrective actions undertaken in response to the Government's audit(s) and
civil and any criminal investigation(s) in connection with the matters covered
by this Agreement (including attorney's fees and the obligations undertaken
pursuant to the Corporate Compliance Agreement incorporated in this Settlement
Agreement), (d) the negotiation of this Agreement, including the Corporate
Compliance Agreement, and (e) the payments made pursuant to this Agreement, are
unallowable costs on Government contracts and under the Medicare Program,
Medicaid Program, TRICARE Program, Veterans Affairs Program, and Federal
Employee Health Benefits Program (hereafter, "unallowable costs"). These
unallowable costs will be separately estimated and accounted for by CHS, and CHS
and its subsidiaries will not charge such unallowable costs directly or
indirectly to any contracts with the United States or any state Medicaid
program, or seek payment for such unallowable costs through any cost report,
cost statement, information statement or payment request


                                     - 9 -
<PAGE>

submitted by CHS or any of its subsidiaries to the Medicare, Medicaid, TRICARE,
VA or FEHBP programs.

         14. CHS further agrees that within 60 days of the effective date of
this Agreement it will identify to applicable Medicare and TRICARE fiscal
intermediaries, carriers and/or contractors, and Medicaid, VA and FEHBP fiscal
agents, any unallowable costs (as defined in Paragraph 13) included in payments
previously sought from the United States, or any State Medicaid Program or MCO,
including, but not limited to, payments sought in any cost reports, cost
statements, information reports, or payment requests already submitted by CHS or
any of its subsidiaries, 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. CHS agrees that the United States and participating States
will be entitled to recoup from CHS or its subsidiaries 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 or participating States pursuant to the direction of the Department of
Justice, and/or the affected agencies or States. The United States and
participating States reserve their rights to disagree with any calculations
submitted by CHS or any of its subsidiaries on the effect of inclusion of
unallowable costs (as defined in Paragraph 13) on CHS or any of its
subsidiaries' cost reports, cost statements or information reports. Nothing in
this Agreement shall constitute a waiver of the rights of the United States or
participating States to examine or reexamine the unallowable costs described in
this Paragraph and Paragraph 13.

         15. 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.

         16. CHS agrees that it will not seek payment for any of the health care
billings covered by this Agreement or the self audit from any health care
beneficiaries or their parents or sponsors. CHS waives any causes of action
against these beneficiaries or their


                                     - 10 -
<PAGE>

parents or sponsors based upon the claims for payment covered by this Agreement
or the self audit.

         17. Each party to this Agreement will bear its own legal and other
costs incurred in connection with this matter, including the preparation and
performance of this Agreement.

         18. CHS represents that this Agreement is freely and voluntarily
entered into without any degree of duress or compulsion whatsoever.

         19. This Agreement is governed by the laws of the United States. The
Parties agree that the exclusive jurisdiction and venue for any dispute arising
between the United States and CHS under this Agreement will be the United States
District Court for the District of Columbia, except that disputes arising under
the Corporate Compliance Agreement (attached as Attachment B) shall be resolved
exclusively under the dispute resolution provisions set forth in that agreement.
The Parties further agree that jurisdiction and venue for any dispute arising
between CHS and any participating State will be the State involved in the
dispute.

         20. This Agreement, including Attachments A and B which are
incorporated by reference, constitutes the complete agreement among the Parties
and supersedes all prior agreements as to the same subject matter, and such
prior agreements shall be null and void and shall have no effect. This Agreement
may not be amended except by written consent of the Parties, except that only
CHS and the OIG-HHS must agree in writing to modification of the Corporate
Compliance Agreement contained in Attachment B.

         21. The undersigned individuals signing this Agreement on behalf of CHS
represent and warrant that they are authorized to execute this Agreement on
behalf of CHS. The undersigned United States signatories and signatories of the
participating States represent that they are signing this Agreement in their
official capacities and that they are authorized to execute this Agreement.

         22. This Agreement is binding on successors, transferees, and assigns.


                                     - 11 -
<PAGE>

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

         24. This Agreement is effective on the date on which the last signatory
to the Agreement signs the Agreement.
