         SECTION 2. Terms of the Guaranty.

                  (a) Guaranty of Obligations. Each Guarantor hereby, jointly
         and severally with the other Guarantors, unconditionally guarantees to
         the Administrative Agent for the ratable benefit of itself and the
         Lenders, and their respective permitted successors, endorsees,
         transferees and assigns, the prompt payment (whether at stated
         maturity, by acceleration or otherwise) and performance of all
         Obligations of the Borrower, whether primary or secondary (whether by
         way of endorsement or otherwise), whether now existing or hereafter
         arising, whether or not from time to time reduced or extinguished
         (except by payment thereof) or hereafter increased or incurred, whether
         or not recovery may be or hereafter become barred by the statute of
         limitations, whether enforceable or unenforceable as against the
         Borrower, whether or not discharged, stayed or otherwise affected by
         any bankruptcy, insolvency or other similar law or proceeding, whether
         created directly with the Administrative Agent or any Lender or
         acquired by the Administrative Agent or any Lender through assignment,
         endorsement or otherwise, whether matured or unmatured, whether joint
         or



                                       12
<PAGE>   13

         several, as and when the same become due and payable (whether at
         maturity or earlier, by reason of acceleration, mandatory repayment or
         otherwise), in accordance with the terms of any such instruments
         evidencing any such Obligations, including all renewals, extensions or
         modifications thereof (all Obligations of the Borrower to the
         Administrative Agent or any Lender under the Loan Agreement and the
         other Loan Documents, including all of the foregoing, being hereinafter
         collectively referred to as the "Guaranteed Obligations").

                  (b) Bankruptcy Limitations on Guarantors. Notwithstanding
         anything to the contrary contained in paragraph (a) above, it is the
         intention of each Guarantor and the Lenders that, in any proceeding
         involving the bankruptcy, reorganization, arrangement, adjustment of
         debts, relief of debtors, dissolution or insolvency or any similar
         proceeding with respect to any Guarantor or its assets, the amount of
         such Guarantor's obligations with respect to the Guaranteed Obligations
         shall be in, but not in excess of, the maximum amount thereof not
         subject to avoidance or recovery by operation of any Applicable
         Insolvency Laws. To that end, but only in the event and to the extent
         that such Guarantor's obligations with respect to the Guaranteed
         Obligations or any payment made pursuant to the Guaranteed Obligations
         would, but for the operation of the first sentence of this Section
         2(b), be subject to avoidance or recovery in any such proceeding under
         Applicable Insolvency Laws, the amount of such Guarantor's obligations
         with respect to the Guaranteed Obligations shall be limited to the
         largest amount which, after giving effect thereto, would not, under
         Applicable Insolvency Laws, render such Guarantor's obligations with
         respect to such Guaranteed Obligations unenforceable or avoidable or
         otherwise subject to recovery under Applicable Insolvency Laws. To the
         extent any payment actually made pursuant to the Guaranteed Obligations
         exceeds the limitation of the first sentence of this Section 2(b) and
         is otherwise subject to avoidance and recovery in any such proceeding
         under Applicable Insolvency Laws, the amount subject to avoidance shall
         in all events be limited to the amount by which such actual payment
         exceeds such limitation and the Guaranteed Obligations as limited by
         the first sentence of this Section 2(b) shall in all events remain in
         full force and effect and be fully enforceable against such Guarantor.
         The first sentence of this Section 2(b) is intended solely to preserve
         the rights of the Administrative Agent hereunder against such Guarantor
         in such proceeding to the maximum extent permitted by Applicable
         Insolvency Laws and neither such Guarantor, the Borrower, any other
         guarantor nor any other Person shall have any right or claim under such
         sentence that would not otherwise be available under Applicable
         Insolvency Laws in such proceeding.

                  (c) Mutual Grant of Present Right of Contribution and
         Indemnity. To the extent that the value as of the time of execution of
         this Guaranty of the benefits received by any Guarantor by reason of
         matters stated in the preamble (whether determined under a standard of
         "fair value," "reasonably equivalent value" or any other valuation
         standard under Applicable Law) is less than the sum of the Guaranteed
         Obligations incurred by such Guarantor to the Administrative



                                       13
<PAGE>   14

         Agent and the Lenders plus such Guarantor's liability under this
         Section 2(c), then subject only to Section 15 hereof and in addition to
         all other rights and remedies such Guarantor has or may have under
         Applicable Law, each remaining Guarantor respectively agrees that such
         Guarantor has the present right to recover the amount of such excess
         from the remaining Guarantors, which right shall be enforceable jointly
         and severally against the remaining Guarantors to the full extent that
         the Guaranteed Obligations are enforceable against such Guarantor.
         Without limiting the foregoing, in the event any Guarantor is required,
         by reason of this Guaranty, to pay an amount in excess of the value of
         the benefit such Guarantor is deemed to have received by reason of
         matters described in the preamble of this Guaranty, the remaining
         Guarantors jointly and severally agree to pay such Guarantor, upon
         demand, the amount of such excess. Subject only to the provisions of
         Section 15 hereof, such Guarantor shall be subrogated to any and all
         rights of the Administrative Agent and the Lenders against the
         remaining Guarantors to the extent of such excess payment.

         SECTION 3. Nature of Guaranty. Each Guarantor agrees that this Guaranty
is a continuing, unconditional guaranty of payment and performance and not of
collection, and that its obligations under this Guaranty shall be primary,
absolute and unconditional, irrespective of, and unaffected by:

                  (a) the genuineness, validity, regularity, enforceability or
         any future amendment of, or change in, this Guaranty, the Loan
         Agreement or any other Loan Document or any other agreement, document
         or instrument to which the Borrower, any Subsidiary thereof or any
         Affiliate thereof is or may become a party;

                  (b) the absence of any action to enforce this Guaranty, the
         Loan Agreement or any other Loan Document or the waiver or consent by
         the Administrative Agent or any Lender with respect to any of the
         provisions of this Guaranty, the Loan Agreement or any other Loan
         Document;

                  (c) the existence, value or condition of, or failure to
         perfect its Lien against, any security (including, without limitation,
         the Collateral) for or other guaranty of the Guaranteed Obligations or
         any action, or the absence of any action, by the Administrative Agent
         or any Lender in respect of such security or guaranty (including,
         without limitation, the release of any such security or guaranty);

                  (d) any structural change in, restructuring of or other
         similar change of the Borrower or any of its Subsidiaries; or

                  (e) any other action or circumstances which might otherwise
         constitute a legal or equitable discharge or defense of a surety or
         guarantor;



                                       14
<PAGE>   15

it being agreed by each Guarantor that, subject to the first sentence in Section
2(b) hereof, its obligations under this Guaranty shall not be discharged until
the final indefeasible payment and performance, in full, of the Guaranteed
Obligations and the termination of the Aggregate Commitment. To the extent
permitted by Applicable Law, each Guarantor expressly waives all rights it may
now or in the future have under any statute (including, without limitation,
North Carolina General Statutes Section 26-7, et seq. or similar law), or at law
or in equity, or otherwise, to compel the Administrative Agent or any Lender to
proceed in respect of the Guaranteed Obligations against the Borrower or any
other party or against any security (including, without limitation, the
Collateral) for or other guaranty of the payment and performance of the
Guaranteed Obligations before proceeding against, or as a condition to
proceeding against, such Guarantor. To the extent permitted by Applicable Law,
each Guarantor further expressly waives and agrees not to assert or take
advantage of any defense based upon the failure of the Administrative Agent or
any Lender to commence an action in respect of the Guaranteed Obligations
against the Borrower, such Guarantor, any other guarantor or any other Person or
any security (including, without limitation, the Collateral) for the payment and
performance of the Guaranteed Obligations. Each Guarantor agrees that any notice
or directive given at any time to the Administrative Agent or any Lender which
is inconsistent with the waivers in the preceding two sentences shall be null
and void and may be ignored by the Administrative Agent or such Lender, and, in
addition, may not be pleaded or introduced as evidence in any litigation
relating to this Guaranty for the reason that such pleading or introduction
would be at variance with the written terms of this Guaranty, unless the
Administrative Agent and the Required Lenders have specifically agreed otherwise
in writing. The foregoing waivers are of the essence of the transaction
contemplated by the Loan Agreement and the other Loan Documents and, but for
this Guaranty and such waivers, the Administrative Agent and the Lenders would
decline to enter into the Loan Agreement and the other Loan Documents.

         SECTION 4. Demand by the Administrative Agent. In addition to the terms
set forth in Section 3 hereof, and in no manner imposing any limitation on such
terms, if all or any portion of the then outstanding Guaranteed Obligations
under the Loan Agreement are declared to be immediately due and payable, then
the Guarantors shall, upon demand in writing therefor by the Administrative
Agent to the Guarantors, pay all or such portion of the outstanding Guaranteed
Obligations then declared due and payable. Payment by the Guarantors shall be
made to the Administrative Agent, to be credited and applied upon the Guaranteed
Obligations, in immediately available Dollars to an account designated by the
Administrative Agent or at the address referenced herein for the giving of
notice to the Administrative Agent or at any other address that may be specified
in writing from time to time by the Administrative Agent.

         SECTION 5. Waivers. In addition to the waivers contained in Section 3
hereof, each Guarantor, to the extent permitted by Applicable Law, waives and
agrees that it shall not at any time insist upon, plead or in any manner
whatever claim or take the benefit or advantage of, any appraisal, valuation,
stay, extension, marshalling of assets or redemption laws, or exemption, whether
now or at any time hereafter in force, which may delay, prevent or otherwise
affect the performance by such Guarantor of its obligations under, or the
enforcement by the Administrative Agent or the Lenders of, this Guaranty. Each
Guarantor further hereby waives, to the extent permitted by Applicable Law,
diligence, presentment, demand, protest and notice



                                       15
<PAGE>   16

(except as specifically required herein) of whatever kind or nature with respect
to any of the Guaranteed Obligations and waives, to the extent permitted by
Applicable Law, the benefit of all provisions of law which are or might be in
conflict with the terms of this Guaranty. Each Guarantor represents, warrants
and agrees that its obligations under this Guaranty are not and shall not be
subject to any counterclaims, offsets or defenses of any kind against the
Administrative Agent, the Lenders or the Borrower whether now existing or which
may arise in the future.

         SECTION 6. Benefits of Guaranty. The provisions of this Guaranty are
for the benefit of the Administrative Agent and the Lenders and their respective
permitted successors, transferees, endorsees and assigns, and nothing herein
contained shall impair, as between the Borrower, the Administrative Agent and
the Lenders, the obligations of the Borrower under the Loan Documents. In the
event all or any part of the Guaranteed Obligations are transferred, endorsed or
assigned by the Administrative Agent or any Lender to any Person or Persons as
permitted under the Loan Agreement, any reference to the "Administrative Agent",
or the "Lenders" herein shall be deemed to refer equally to such Person or
Persons.

         SECTION 7. Modification of Loan Documents etc. If the Administrative
Agent or the Lenders shall at any time or from time to time, with or without the
consent of, or notice to, the Guarantors:

                  (a) change or extend the manner, place or terms of payment of,
         or renew or alter all or any portion of, the Guaranteed Obligations;

                  (b) take any action under or in respect of the Loan Agreement
         or the other Loan Documents in the exercise of any remedy, power or
         privilege contained therein or available to it at law, in equity or
         otherwise, or waive or refrain from exercising any such remedies,
         powers or privileges;

                  (c) amend or modify, in any manner whatsoever, the Loan
         Agreement or the other Loan Documents;

                  (d) extend or waive the time for performance by any Guarantor,
         any other guarantor, the Borrower or any other Person of, or compliance
         with, any term, covenant or agreement on its part to be performed or
         observed under the Loan Agreement or any other Loan Document, or waive
         such performance or compliance or consent to a failure of, or departure
         from, such performance or compliance;

                  (e) take and hold security or collateral (including, without
         limitation, the Collateral) for the payment of the Guaranteed
         Obligations or sell, exchange, release, dispose of, or otherwise deal
         with, any property (including, without limitation, the Collateral)
         pledged, mortgaged or conveyed, or in which the Administrative Agent or
         the Lenders have been granted a Lien, to secure any Debt of any
         Guarantor, any other guarantor or the Borrower to the Administrative
         Agent or the Lenders;



                                       16
<PAGE>   17

                  (f) release anyone who may be liable in any manner for the
         payment of any amounts owed by any Guarantor, any other guarantor or
         the Borrower to the Administrative Agent or any Lender;

                  (g) modify or terminate the terms of any intercreditor or
         subordination agreement pursuant to which claims of other creditors of
         any Guarantor, any other guarantor or the Borrower are subordinated to
         the claims of the Administrative Agent or any Lender; or

                  (h) apply any sums by whomever paid or however realized to any
         Guaranteed Obligations owing by any Guarantor, any other guarantor or
         the Borrower to the Administrative Agent or any Lender in such manner
         as the Administrative Agent or any Lender shall determine in its
         reasonable discretion;

then neither the Administrative Agent nor any Lender shall incur any liability
to any Guarantor as a result thereof, and no such action shall impair or release
the obligations of any Guarantor under this Guaranty.

         SECTION 8. Reinstatement. Each Guarantor agrees that, if any payment
made by the Borrower or any other Person applied to the Obligations is at any
time annulled, set aside, rescinded, invalidated, declared to be fraudulent or
preferential or otherwise required to be refunded or repaid or the proceeds of
any collateral are required to be refunded by the Administrative Agent or any
Lender to the Borrower, its estate, trustee, receiver or any other party,
including, without limitation, any Guarantor, under any Applicable Law or
equitable cause, then, to the extent of such payment or repayment, each
Guarantor's liability hereunder (and any Lien securing such liability) shall be
and remain in full force and effect, as fully as if such payment had never been
made, and, if prior thereto, this Guaranty shall have been canceled or
surrendered (and if any Lien or collateral securing such Guarantor's liability
hereunder shall have been released or terminated by virtue of such cancellation
or surrender), this Guaranty (and such Lien) shall be reinstated in full force
and effect, and such prior cancellation or surrender shall not diminish,
release, discharge, impair or otherwise affect the obligations of such Guarantor
in respect of the amount of such payment (or any Lien securing such obligation).

         SECTION 9. Representations and Warranties.

         (a) Representations and Warranties. To induce the Lenders to make the
Term Loans, each Guarantor hereby represents and warrants to the Administrative
Agent and the Lenders both before and after giving effect to the transactions
contemplated under the Loan Agreement:

                  (i) Ownership. Each Subsidiary and each Hospital Joint Venture
         owned by the Parent, either directly or indirectly, is listed on
         Schedule 9(a)(i) (as updated from time to time pursuant to Section
         11(j)). As of the Closing Date, the capitalization of the Parent, its
         Subsidiaries and each Hospital Joint Venture consists of the number of
         shares or other ownership interests, authorized, issued and
         outstanding, of such classes and series, with or without par value,
         described on



                                       17
<PAGE>   18

         Schedule 9(a)(i). All outstanding shares or other ownership interests
         have been duly authorized and validly issued and are fully paid and
         nonassessable, with no personal liability attaching to the ownership
         thereof, and not subject to any preemptive or similar rights. The
         shareholders of the Subsidiaries and the Hospital Joint Ventures owned
         by the Parent, either directly or indirectly, and the number of shares
         or other ownership interests owned by each as of the Closing Date are
         described on Schedule 9(a)(i). As of the Closing Date, there are no
         outstanding stock purchase warrants, subscriptions, options,
         securities, instruments or other rights of any type or nature
         whatsoever, which are convertible into, exchangeable for or otherwise
         provide for or permit the issuance of capital stock or other ownership
         interests of the Parent, any Subsidiary, or any Hospital Joint Venture
         except as described on Schedule 9(a)(i).

                  (ii) Organization; Power; Qualification. Each Guarantor is
         duly organized, validly existing and in good standing under the laws of
         the jurisdiction of its incorporation or formation, has the power and
         authority to own its properties and to carry on its business as now
         being and hereafter proposed to be conducted and is duly qualified and
         authorized to do business in each jurisdiction in which the character
         of its properties or the nature of its business requires such
         qualification and authorization, except where the failure to so qualify
         could not reasonably be expected to have a Material Adverse Effect. The
         jurisdictions in which each Guarantor is organized and qualified to do
         business as of the Closing Date are described on Schedule 9(a)(ii) (as
         updated from time to time pursuant to Section 11(j)).

                  (iii) Authorization of Guaranty and Loan Documents. Each
         Guarantor has the corporate or limited liability company right, power
         and authority to execute, deliver and perform this Guaranty and each of
         the other Loan Documents to which such Guarantor is a party and has
         taken all necessary corporate or limited liability company action to
         authorize its execution, delivery and performance of, this Guaranty and
         each of the other Loan Documents to which such Guarantor is a party.

                  (iv) Enforceability of Guaranty and Loan Documents. This
         Guaranty and each of the other Loan Documents to which each Guarantor
         is a party constitutes the legal, valid and binding obligation of such
         Guarantor enforceable in accordance with its terms, except as
         enforceability may be limited by bankruptcy, insolvency,
         reorganization, moratorium or similar laws affecting the enforcement of
         creditors' rights generally and by the availability of equitable
         remedies.

                  (v) Compliance with Laws, Etc. The execution, delivery and
         performance of this Guaranty and each of the other Loan Documents to
         which each Guarantor is a party will not violate any Applicable Law or
         contractual obligation of such Guarantor and will not result in the
         creation or imposition of any Lien upon or with respect to any property
         or revenues of such Guarantor.

                  (vi) Consents and Authorizations. No consent or authorization
         of, filing with, or other act by or in respect of, any arbitrator or
         Governmental Authority and no consent of any other Person (including,
         without limitation, any stockholder or creditor of each Guarantor), is
         required in connection with the execution, delivery, performance,
         validity or enforceability of this Guaranty or any of the other Loan
         Documents to which such Guarantor is a party, other than the approval
         of the board of directors of each Guarantor (which approval has been
         obtained prior to the date hereof).

                  (vii) Litigation. Except for matters set forth on Schedule
         9(a)(vii), no actions, suits or proceedings before any arbitrator or
         Governmental Authority are pending or, to the knowledge of each
         Guarantor, threatened by or against such Guarantor or against any of
         its properties with respect to this Guaranty, any other Loan Document
         or any of the transactions contemplated hereby or thereby which could
         reasonably be expected to have a Material Adverse Effect.

                  (viii) Title to Properties. Each Guarantor has such title to
         the real property owned by it and a valid leasehold interest in the
         real property leased by it, and has good and marketable title to all of
         its personal property sufficient to carry on its business free of any
         and all Liens of any type whatsoever.

                  (ix) Solvency. As of the Closing Date (or such later date upon
         which such Guarantor became a party hereto), each Guarantor (A) has
         capital sufficient to carry on its business and transactions and all
         business and transactions in which it engages and is able to pay its
         debts as they mature, (B) owns property having a value, both at fair
         valuation and at present fair saleable value on a going concern basis,
         greater than the amount required to pay its probable liabilities
         (including contingencies) and (C) does not believe that it will incur
         debts or liabilities beyond its ability to pay such debts or
         liabilities as they mature, subject in each case to the first sentence
         in Section 2(b) hereof.

                  (x) Financial Statements. The (A) audited Consolidated balance
         sheet of the Parent and its Subsidiaries as of September 30, 2000 and
         the related audited statements of income and retained earnings and cash
         flows for the Fiscal Year of the Parent and its Subsidiaries then ended
         and (B) unaudited Consolidated balance sheet of the Parent and its
         Subsidiaries as of March 31, 2001 and the related unaudited statements
         of income and retained earnings and cash flows for the fiscal quarter
         of the Parent and its Subsidiaries then ended, copies of which has been
         furnished to Administrative Agent and the Lenders, are complete and
         correct in all material respects and fairly present on a Consolidated
         basis the assets, liabilities and financial position of the Parent and
         its Subsidiaries as of such dates and the results of its operations and
         cash flows for the periods then ended.

                  (xi) No Material Adverse Change. Since September 30, 2000,
         there has been no Material Adverse Effect with respect to any Guarantor
         or the Guarantors



                                       19

         taken as a whole, as applicable, and no event has occurred or condition
         arisen that could reasonably be expected to have a Material Adverse
         Effect.

                  (xii) Tax Returns and Payments. Each Guarantor has duly filed
         or caused to be filed all federal, state, local and other tax returns
         required by Applicable Law to be filed, and has paid, or made adequate
         provision for the payment of, all federal, state, local and other
         material taxes, assessments and governmental charges or levies upon it
         and its property, income, profits and assets which are due and payable,
         except for taxes (i) that are not yet delinquent or (ii) that are being
         contested in good faith and against which adequate reserves are being
         maintained in accordance with GAAP; such returns accurately reflect in
         all material respects all liability for taxes of such Guarantor for the
         periods covered thereby; there is no ongoing audit or examination or,
         to the knowledge of the such Guarantor, other investigation by any
         Governmental Authority of the tax liability of such Guarantor; no
         Governmental Authority has asserted any Lien or other claim against
         such Guarantor with respect to unpaid taxes which has not been
         discharged or resolved; and the charges, accruals and reserves on the
         books of such Guarantor in respect of federal, state, local and other
         taxes for all Fiscal Years and portions thereof since the organization
         of such Guarantor are in the judgment of such Guarantor adequate, and
         such Guarantor does not anticipate any additional material taxes or
         assessments for any of such periods.

                  (xiii) Environmental Matters.

                           (A) The properties owned, leased or operated by each
                  Guarantor now or in the past do not contain, and to its
                  knowledge have not previously contained, any Hazardous
                  Materials in amounts or concentrations which (1) constitute or
                  constituted a material violation of applicable Environmental
                  Laws or (2) could give rise to a material liability under
                  applicable Environmental Laws;

                           (B) Each Guarantor and such properties and all
                  operations conducted in connection therewith are in compliance
                  in all material respects with all applicable Environmental
                  Laws, and there is no contamination at, under or about such
                  properties or such operations which could reasonably interfere
                  with the continued operation of such properties or impair the
                  fair saleable value thereof;

                           (C) No Guarantor has received any notice of
                  violation, alleged violation, non-compliance, liability or
                  potential liability regarding environmental matters, Hazardous
                  Materials, or compliance with Environmental Laws from (A) any
                  Governmental Authority or (B) to the extent any such
                  violation, alleged violation, non-compliance, liability or
                  potential liability could reasonably be expected to have a
                  Material Adverse Effect, any other Person, nor does any
                  Guarantor have knowledge or reason to believe that any such
                  notice will be received or is being threatened;



                                       20

                           (D) Hazardous Materials have not been transported or
                  disposed of to or from the properties owned, leased or
                  operated by of any Guarantor in violation of, or in a manner
                  or to a location which could give rise to a material liability
                  under, Environmental Laws, nor have any Hazardous Materials
                  been generated, treated, stored or disposed of at, on or under
                  any of such properties in violation of, or in a manner that
                  could give rise to a material liability under, any applicable
                  Environmental Laws;

                           (E) No judicial proceedings or governmental or
                  administrative action is pending, or, to the knowledge of any
                  Guarantor, threatened, under any Environmental Law to which
                  such Guarantor is or will be named as a potentially
                  responsible party with respect to such properties or
                  operations conducted in connection therewith, nor are there
                  any consent decrees or other decrees, consent orders,
                  administrative orders or other orders, or other administrative
                  or judicial requirements outstanding under any Environmental
                  Law with respect to such Guarantor or such properties or such
                  operations; and

                           (F) There has been no release, or to the best of any
                  Guarantor's knowledge, threat of release, of Hazardous
                  Materials at or from properties owned, leased or operated by
                  such Guarantor, now or in the past, in violation of or in
                  amounts or in a manner that could give rise to a material
                  liability under Environmental Laws.

                  (xiv) ERISA.

                           (A) The Parent and each ERISA Affiliate is in
                  material compliance with all applicable provisions of ERISA
                  and the regulations and published interpretations thereunder
                  with respect to all Employee Benefit Plans except for any
                  required amendments for which the remedial amendment period as
                  defined in Section 401(b) of the Code has not yet expired and
                  except where a failure to so comply could not reasonably be
                  expected to have a Material Adverse Effect. Each Employee
                  Benefit Plan that is intended to be qualified under Section
                  401(a) of the Code has been determined by the Internal Revenue
                  Service to be so qualified, and each trust related to such
                  plan has been determined to be exempt under Section 501(a) of
                  the Code except for such plans that have not yet received
                  determination letters but for which the remedial amendment
                  period for submitting a determination letter has not yet
                  expired. No liability has been incurred by the Parent or any
                  ERISA Affiliate which remains unsatisfied for any taxes or
                  penalties with respect to any Employee Benefit Plan or any
                  Multiemployer Plan except for a liability that could not
                  reasonably be expected to have a Material Adverse Effect;



                                       21
<PAGE>   22

                           (B) As of the Closing Date, no Pension Plan has been
                  terminated, nor has any accumulated funding deficiency (as
                  defined in Section 412 of the Code) been incurred (without
                  regard to any waiver granted under Section 412 of the Code),
                  nor has any funding waiver from the Internal Revenue Service
                  been received or requested with respect to any Pension Plan,
                  nor has the Parent or any ERISA Affiliate failed to make any
                  contributions or to pay any amounts due and owing as required
                  by Section 412 of the Code, Section 302 of ERISA or the terms
                  of any Pension Plan prior to the due dates of such
                  contributions under Section 412 of the Code or Section 302 of
                  ERISA, nor has there been any event requiring any disclosure
                  under Section 4041(c)(3)(C) or 4063(a) of ERISA with respect
                  to any Pension Plan;

                           (C) Except where the failure of any of the following
                  representations to be correct in all material respects could
                  not reasonably be expected to have a Material Adverse Effect,
                  neither the Parent nor any ERISA Affiliate has: (1) engaged in
                  a nonexempt prohibited transaction described in Section 406 of
                  the ERISA or Section 4975 of the Code, (2) incurred any
                  liability to the PBGC which remains outstanding other than the
                  payment of premiums and there are no premium payments which
                  are due and unpaid, (3) failed to make a required contribution
                  or payment to a Multiemployer Plan, or (4) failed to make a
                  required installment or other required payment under Section
                  412 of the Code;

                           (D) No Termination Event has occurred or is
                  reasonably expected to occur; and

                           (E) Except where the failure of any of the following
                  representations to be correct in all material respects could
                  not reasonably be expected to have a Material Adverse Effect,
                  no proceeding, claim (other than a benefits claim in the
                  ordinary course of business), lawsuit and/or investigation is
                  existing or, to the best knowledge of the Parent after due
                  inquiry, threatened concerning or involving any (1) employee
                  welfare benefit plan (as defined in Section 3(1) of ERISA)
                  currently maintained or contributed to by the Parent or any
                  ERISA Affiliate, (2) Pension Plan or (3) Multiemployer Plan.

                  (xv) Accuracy and Completeness of Information. All written
         information, reports, statements and other papers and data produced by
         or on behalf of the Parent or any Subsidiary thereof and furnished to
         the Administrative Agent or any Lender in connection with this
         Guaranty, or any of the other Loan Documents, were, at the time the
         same were so furnished, complete and correct in all material respects
         to the extent necessary to give the Administrative Agent or any Lender
         complete, true and accurate knowledge of the subject matter based on
         Parent's knowledge thereof (other than projections, budgets or other
         estimates which shall be determined in good faith utilizing reasonable
         assumptions). No



                                       22
<PAGE>   23

         document furnished or written statement made to the Administrative
         Agent or the Lenders by the Parent or any Subsidiary thereof in
         connection with the negotiation, preparation or execution of this
         Guaranty or any of the Loan Documents contains or will contain any
         untrue statement of a fact material to the creditworthiness of the
         Parent or its Subsidiaries or omits or will omit to state a fact
         necessary in order to make the statements contained therein not
         misleading to the extent material to the creditworthiness of the Parent
         or its Subsidiaries. The Parent is not aware of any facts which it has
         not disclosed in writing to the Administrative Agent having a Material
         Adverse Effect, or insofar as the Parent can now foresee, which could
         reasonably be expected to have a Material Adverse Effect.

         (b) Survival of Representations and Warranties, Etc. All
representations and warranties set forth in this Section 9 and all
representations and warranties of the Guarantors contained in any certificate,
or any of the Loan Documents (including, but not limited to, any such
representation or warranty made in or in connection with any amendment thereto)
shall constitute representations and warranties made under this Guaranty. All
representations and warranties made under this Guaranty shall be made or deemed
to be made at and as of the Closing Date (except those that are expressly made
as of a specific date), shall survive the Closing Date and shall not be waived
by the execution and delivery of this Guaranty, any investigation made by or on
behalf of the Lenders or any borrowing hereunder.

         SECTION 10. Financial Information and Reports. Until all Obligations
have been finally and indefeasibly paid and satisfied in full and the
Commitments of the Lenders under the Loan Agreement have been terminated, unless
consent has been obtained in the manner provided for in Section 19, the Parent
will furnish, or cause to be furnished to the Administrative Agent and the
Lenders at their respective addresses as set forth on Schedule 1, or such other
office as may be designated by the Administrative Agent and the Lenders from
time to time:

                  its Subsidiaries in accordance with GAAP and certified by a
                  Responsible Officer of Parent to present fairly in all

                  respective periods then ended, subject to normal year end
                  adjustments.

                  of nationally recognized standing which is reasonably
                  acceptable to the Administrative Agent, that such financial
                  statements are not qualified with respect to scope limitations
                  imposed by Parent and its Subsidiaries or with respect to
                  accounting principles followed by Parent and its Subsidiaries
                  not in accordance with GAAP.

                           (C) As soon as practicable and in any event within

         assets; provided that any Subsidiary Guarantor may be merged or
         consolidated with or into, or be liquidated, wound up or dissolved, or

         to the conduct of its business, and qualify and remain qualified to do
         business in each jurisdiction in which the failure to so qualify would
         have a Material Adverse Effect.

         (b) Compliance with Laws and Approvals. Observe and remain in
compliance with all Applicable Laws and maintain in full force and effect all
Governmental Approvals, in each case applicable to the conduct of its business,
except were the failure to observe or comply could not reasonably be expected to

condition and provision of each Material Contract to which it is a party or by
which it is bound and with all other material leases, agreements and other
instruments entered into in the conduct of its business, except (i) where the
failure to so comply could not reasonably be expected to have a Material Adverse

faith through applicable proceedings and where adequate reserves are maintained

<PAGE>   28

         (e) Accounting Methods and Financial Records. Maintain a system of
accounting, and keep such books, records and accounts (which shall be true and
complete in all material respects) as may be required or as may be necessary to
permit the preparation of financial statements in accordance with GAAP and in
compliance with the regulations of any Governmental Authority having
jurisdiction over it or any of its properties.

         (f) Payment and Performance of Obligations. Pay and perform all
obligations under this Guaranty and the other Loan Documents, and pay or perform
(i) all taxes, assessments and other governmental charges that may be levied or
assessed upon it or any of its property, and (ii) all other indebtedness,
obligations and liabilities in accordance with customary trade practices;
provided, that each Guarantor and each of its Subsidiaries may contest any item
described in clauses (i) or (ii) of this Section 11(f) in good faith so long as
adequate reserves are maintained with respect thereto in accordance with GAAP.

         (g) Visits and Inspections. Upon reasonable notice to the Parent
(unless there exists any Default or Event of Default), permit representatives of
the Administrative Agent or any Lender, from time to time, to visit and inspect
its properties and any materials thereon; inspect, audit and make extracts from
its books, records and files, including, but not limited to, management letters
prepared by independent accountants; and discuss with its principal officers,
and its independent accountants, its business, assets, liabilities, financial
condition, results of operations and business prospects.

         (h) Insurance. Maintain insurance with financially sound and reputable
insurance companies against such risks and in such amounts as are customarily
maintained by similar businesses and as may be required by Applicable Law, and
on the Closing Date and from time to time thereafter deliver to the
Administrative Agent upon its request a detailed list of the insurance then in
effect, stating the names of the insurance companies, the amounts and rates of
the insurance, the dates of the expiration thereof and the properties and risks
covered thereby.

         (i) Conduct of Business. Engage only in businesses in substantially the
same fields as the businesses conducted or proposed to be conducted in
accordance with business plans delivered to the Administrative Agent and the
Lenders on or prior to the Closing Date or in lines of business reasonably
related thereto.

         (j) New Subsidiaries. Concurrently with the creation or acquisition of
any Subsidiary by the Parent (other than any Hospital Joint Venture) which is
not a "controlled foreign corporation" under Section 957 of the Code, cause such
Subsidiary to:

                  (i) execute a Joinder Agreement in substantially the same form
         as Exhibit A attached hereto; and

                  (ii) deliver to the Administrative Agent, with the Joinder
         Agreement, such other documentation as the Administrative Agent may
         reasonably request, including, certified resolutions and other
         organizational and authorizing documents of such Subsidiary, favorable
         opinions of counsel to such Subsidiary (which shall cover, among



                                       28
<PAGE>   29

         other things, the legality, validity, binding effect and enforceability
         of the Joinder Agreement), all in form and substance satisfactory to
         the Administrative Agent.

For the purposes of this Section 11(j), a Subsidiary shall not be deemed to have
been created or acquired until the earlier of (i) the date upon which such
Subsidiary begins to conduct business operations, (ii) the date upon which such
Subsidiary obtains assets with a fair market value in excess of $10,000.00 or
(iii) the date upon which such Subsidiary is initially capitalized.

         (k) Transactions with Affiliates. Conduct all transactions otherwise
permitted under this Guaranty, the Loan Agreement and the other Loan Documents
with any of their Affiliates on terms that are fair and reasonable and no less
favorable to such Guarantor or such Subsidiary than it would obtain in a
comparable arm's length transaction with a Person not an Affiliate.

         (l) Subordinated Working Capital Loan.

                  (i) Cause FinCo to make working capital advances to the
         Borrower in an amount necessary to ensure that the Borrower can meet
         all of its working capital and other general corporate needs (the
         "Working Capital Advances");

                  (ii) Immediately upon the request of the Administrative Agent
         or the Required Lenders, cause FinCo to make additional Working Capital
         Advances to the Borrower (in addition to any Working Capital Advances
         made to the Borrower pursuant to clause (i) above); provided that FinCo
         shall not be required to make such Working Capital Advances to the
         extent that the sum of (A) the aggregate amount of such Working Capital
         Advances plus (B) the aggregate amount of Subordinated Working Capital
         Loans outstanding as of any applicable date of determination would
         exceed $14,500,000; and

                  (iii) Cause all Working Capital Advances to be subordinated
         pursuant to an Intercompany Loan Subordination Agreement in form and
         substance satisfactory to the Administrative Agent.

         SECTION 12. Financial Covenants. Until all of the Obligations have been
paid and satisfied in full and the Commitments of the Lenders under the Loan
Agreement have been terminated, unless consent has been obtained in the manner
provided for in Section 19, the Parent and its Subsidiaries on a Consolidated

         section, exhibit or schedule referenced in or relating to such Section
         5.02 of the Corporate Revolver) was written herein; provided that the

<PAGE>   32

         amendment, restatement, refinancing or replacement thereof, the
         "Corporate Revolver Debt") shall not exceed $125,000,000 unless (A) the
         Obligations, the Guaranteed Obligations and all other obligations under
         the Related Credit Documents (as defined in the Loan Agreement) shall
         be secured on a pari passu basis with the Corporate Revolver Debt or
         (B) the Corporate Revolver Debt shall be unsecured; and

                  (ii) Notify the Administrative Agent and the Lenders promptly
         upon the execution of any amendment, restatement, supplement or other
         modification to the Corporate Revolver.

         (b) Rules of Construction.

                  (i) The terms and conditions of the Corporate Revolver which
         are incorporated in this Guaranty by reference shall continue as such
         terms and conditions are set forth in the Corporate Revolver
         irrespective of any termination of the Corporate Revolver. Such terms
         and conditions shall include any amendments, restatements, supplements
         or other modifications which are approved by the Required Lender
         pursuant to Section 5(a)(ii).

                  (ii) All definitions and other provisions of the Corporate
         Revolver which are incorporated herein by reference shall be construed
         in such a manner so as to give such incorporated terms legal effect and
         meaning hereunder. More specifically, any references to the terms
         defined in both the Corporate Revolver and this Guaranty shall be
         deemed references to such terms as defined herein; provided that any
         references to the "Borrower" and the "Parent" in the Corporate Revolver
         shall be deemed to be references to MedCath Intermediate Holdings, Inc.
         and MedCath Holdings, Inc. hereunder. For example, references in the
         Corporate Revolver to the "Loan Documents", the "Commitments", the
         "Obligations", the "Administrative Agent" and the "Lenders" shall be
         deemed to be references to the Loan Documents, the Commitments, the
         Obligations, the Administrative Agent and the Lenders as defined in
         this Guaranty, in each case to the extent necessary to give any such
         incorporated provisions legal effect and meaning hereunder. In
         addition, any references to defined terms in the Corporate Revolver
         which are similarly defined in this Guaranty shall be deemed references
         to such similar terms as defined herein. For example, references in the
         Corporate Revolver to an "Advance" shall be deemed to be references to
         a "Term Loan" hereunder, in each case to the extent necessary to give
         any such incorporated provisions legal effect and meaning hereunder.

         SECTION 14. Remedies. Upon the occurrence and during the continuance of
any Default or Event of Default, with the consent of the Required Lenders, the
Administrative Agent may, or upon the request of the Required Lenders, the
Administrative Agent shall, enforce against the Guarantors their respective
obligations and liabilities hereunder and exercise such other rights and
remedies as may be available to the Administrative Agent hereunder, under the
Loan Agreement or the other Loan Documents or otherwise.

         SECTION 15. No Subrogation. Notwithstanding any payment or payments by
any of the Guarantors hereunder, or any set-off or application of funds of any
of the Guarantors by the Administrative Agent or any Lender, or the receipt of
any amounts by the Administrative



                                       32
<PAGE>   33

Agent or any Lender with respect to any of the Guaranteed Obligations, none of
the Guarantors shall be entitled to be subrogated to any of the rights of the
Administrative Agent or any Lender against the Borrower or the other Guarantors
or any other guarantor or against any collateral security (including, without
limitation, the Collateral) held by the Administrative Agent or any Lender for
the payment of the Guaranteed Obligations nor shall any of the Guarantors seek
any reimbursement from the Borrower or any of the other Guarantors in respect of
payments made by such Guarantor in connection with the Guaranteed Obligations,
until all amounts owing to the Administrative Agent and the Lenders on account
of the Guaranteed Obligations are paid in full and the Aggregate Commitment is
terminated. If any amount shall be paid to any Guarantor on account of such
subrogation rights at any time when all of the Guaranteed Obligations shall not
have been paid in full, such amount shall be held by such Guarantor in trust for
the Administrative Agent and the Lenders, segregated from other funds of such
Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over
to the Administrative Agent in the exact form received by such Guarantor (duly
endorsed by such Guarantor to the Administrative Agent, if required) to be
applied against the Guaranteed Obligations, whether matured or unmatured, in
such order as set forth in the Loan Agreement.

         SECTION 16. Expenses. All costs and expenses (including reasonable
attorneys' fees, legal expenses and court costs) incurred by the Administrative
Agent or any Lender in enforcing or protecting their rights or remedies
hereunder shall be payable by the Guarantors on demand and shall bear interest
(after as well as before judgment) until paid at the interest rate then
applicable to Base Rate Loans under the Loan Agreement and shall be additional
Guaranteed Obligations hereunder.

         SECTION 17. Notices. All notices and communications hereunder shall be
made in accordance with Section 12.1 of the Loan Agreement; provided that
notices and communications to the Guarantors shall be directed to the Guarantors
at the address of the Parent set forth in Section 12.1 of the Loan Agreement.

         SECTION 18. Successors and Assigns. This Guaranty is for the benefit of
the Administrative Agent and the Lenders and their permitted successors and
assigns. This Guaranty shall be binding on each Guarantor and its successors and
assigns; provided that no Guarantor may assign any of its rights or obligations
hereunder without the prior written consent of the Administrative Agent and the
Lenders.

         SECTION 19. Amendments, Waivers and Consents. No term, covenant,
agreement or condition of this Guaranty may be amended or waived, nor may any
consent be given, except in the manner set forth in Section 12.11 of the Loan
Agreement.

         SECTION 20. Powers Coupled with an Interest. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

         SECTION 21. Governing Law. THIS GUARANTY SHALL BE GOVERNED BY,
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH
CAROLINA, WITHOUT REFERENCE TO THE CONFLICTS OR CHOICE OF LAW PRINCIPLES
THEREOF; PROVIDED, THAT THE ADMINISTRATIVE



                                       33
<PAGE>   34

AGENT AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

         SECTION 22. Jurisdiction and Venue.

         (a) Jurisdiction. The Guarantors hereby irrevocably consent to the
personal jurisdiction of the state and federal courts located in Mecklenburg
County, North Carolina, in any action, claim or other proceeding arising out of
any dispute in connection with this Guaranty and the other Loan Documents, any
rights or obligations hereunder, or the performance of such rights and
obligations. The Guarantors hereby irrevocably consent to the service of a
summons and complaint and other process in any action, claim or proceeding
brought by the Administrative Agent or any Lender in connection with this
Guaranty any the other Loan Documents, any rights or obligations hereunder, or
the performance of such rights and obligations, on behalf of itself or its
property, in the manner specified in Section 12.1 of the Loan Agreement. Nothing
in this Section 22 shall affect the right of the Administrative Agent or any
Lender to serve legal process in any other manner permitted by Applicable Law or
affect the right of the Administrative Agent or any Lender to bring any action
or proceeding against any Guarantor or its properties in the courts of any other
jurisdictions.

         (b) Venue. Each Guarantor hereby irrevocably waives any objection it
may have now or in the future to the laying of venue in the aforesaid
jurisdiction in any action, claim or other proceeding arising out of or in
connection with this Guaranty, any other Loan Document or the rights and
obligations of the parties hereunder. Each Guarantor irrevocably waives, in
connection with such action, claim or proceeding, any plea or claim that the
action, claim or other proceeding has been brought in an inconvenient forum.

         SECTION 23. Waiver of Right to Trial by Jury. EACH PARTY TO THIS
GUARANTY HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER THIS GUARANTY OR IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR
ANY OF THEM WITH RESPECT TO THIS GUARANTY, OR THE TRANSACTIONS RELATED THERETO,
IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN
CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT
ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT
TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS GUARANTY MAY FILE AN ORIGINAL
COUNTERPART OR A COPY OF THIS SECTION 23 WITH ANY COURT AS WRITTEN EVIDENCE OF
THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY
JURY.

         SECTION 24. Injunctive Relief; Punitive Damages.

         (a) Injunctive Relief. Each Guarantor recognizes that, in the event
such Guarantor fails to perform, observe or discharge any of its obligations or
liabilities under this Guaranty, any remedy of law may prove to be inadequate
relief to the Lenders. Therefore, each Guarantor agrees that the



                                       34
<PAGE>   35

Lenders, at the Lenders' option, shall be entitled to temporary and permanent
injunctive relief in any such case without the necessity of proving actual
damages.

         (b) Punitive Damages. Each Guarantor agrees that it shall not have a
remedy of punitive or exemplary damages against any other party to a Loan
Document and each such Guarantor hereby waives any right or claim to punitive or
exemplary damages that it may now have or which may arise in the future in
connection with any dispute, whether the dispute is resolved by arbitration or
judicially.

         SECTION 25. Severability. If any provision hereof is invalid and
unenforceable in any jurisdiction, then, to the fullest extent permitted by law,
(a) the other provisions hereof shall remain in full force and effect in such
jurisdiction and shall be liberally construed in favor of the Administrative
Agent and the Lenders in order to carry out the intentions of the parties hereto
as nearly as may be possible; and (b) the invalidity or unenforceability of any
provisions hereof in any jurisdiction shall not affect the validity or
enforceability of such provision in any other jurisdiction.

         SECTION 26. Headings. The various headings of this Guaranty are
inserted for convenience only and shall not affect the meaning or interpretation
of this Guaranty or any provisions hereof.

         SECTION 27. Counterparts. This Guaranty may be executed by the parties
hereto in several counterparts, each of which shall be deemed to be an original
and all of which shall constitute together but one and the same agreement.

         SECTION 28. Accounting Matters.

         (a) All financial and accounting calculations, measurements and
computations made for any purpose relating to this Guaranty, including, without
limitation, all computations utilized by the Guarantors to determine compliance
with any covenant contained herein, shall, except as otherwise expressly
contemplated hereby or unless there is an express written direction by the
Administrative Agent to the contrary agreed to by the Parent, be performed in
accordance with GAAP as in effect on the Closing Date. In the event that changes
in GAAP shall be mandated by the Financial Accounting Standards Board, or any
similar accounting body of comparable standing, or shall be recommended by the
Parent's certified public accountants, to the extent that such changes would
modify such accounting terms or the interpretation or computation thereof, such
changes shall be followed in defining such accounting terms only from and after
the date the Parent and the Required Lenders shall have amended this Guaranty to
the extent necessary to reflect any such changes in the financial covenants and
other terms and conditions of this Guaranty.

         (b) For the purposes of computing the financial covenants set forth in
Section 12 of this Guaranty for any applicable period, such financial covenants
(and the related definitions) shall be calculated on a pro forma basis to
include as of the first day of any such period any permitted acquisition of
assets (including stock) and calculated on a pro forma basis to exclude as of
the first day of any such period any permitted sale of assets (including stock).
Such calculations shall be made in a manner, in form and substance, reasonably
satisfactory to the Administrative Agent.

                        Officer's Compliance Certificate

         The undersigned, on behalf of MedCath Corporation, a corporation
organized under the laws of Delaware (the "Parent"), hereby certifies to the
Administrative Agent and the Lenders, each as defined below, as follows:

         1. This Certificate is delivered to you pursuant to Section 10(b) of
the Guaranty Agreement dated as of July [26], 2001 (as amended, restated,
supplemented or otherwise modified from time to time, the "Guaranty Agreement"),
made by the Parent and certain Subsidiaries of the Parent who are or may become
party thereto (collectively, the "Guarantors"), in favor of Bank of America,
N.A., as administrative agent (the "Administrative Agent") for the ratable
benefit of itself and the financial institutions (collectively, the "Lenders")
from time to time party to the Loan Agreement referred to therein. Capitalized
terms used herein and not defined herein shall have the meanings assigned
thereto in the Guaranty Agreement.

         2. I have reviewed the financial statements of the Parent and its
Subsidiaries dated as of _______________ and for the _______________ period[s]
then ended and, to the best of my knowledge, such statements fairly present in
all material respects the financial condition of the Parent and its Subsidiaries
as of the dates indicated and the results of their operations and cash flows for
the period[s] indicated.

         3. I have reviewed the terms of the Guaranty Agreement, the Loan
Agreement, and the other related Loan Documents and have made, or caused to be
made under my supervision, a review in reasonable detail of the transactions and
the condition of the Parent and its Subsidiaries during the accounting period
covered by the financial statements referred to in Paragraph 2 above. Such
review has not disclosed, to my knowledge, the existence during or at the end of
such accounting period of any condition or event that constitutes a Default or
an Event of Default, nor do I have any knowledge of the existence of any such
condition or event as at the date of this Certificate [except, if such condition
or event existed or exists, describe the nature and period of existence thereof
and what action the Parent and its Subsidiaries have taken, are taking and
propose to take with respect thereto].

         4. The Parent and its Subsidiaries are in compliance with the financial
covenants contained in Section 12 of the Guaranty Agreement as shown on such
Schedule 1 and the Parent and its Subsidiaries are in compliance with the other
covenants and restrictions contained in the Guaranty Agreement.
