                                 LOAN AGREEMENT

     This Loan Agreement is entered into as of the 24th day of March, 1997, by
and among PHYSICIANS RESOURCE GROUP, INC. ("Borrower"), a Delaware corporation;
the banks that have executed this Agreement below (collectively "Lenders"); and
NATIONSBANK OF TENNESSEE, N.A., in its capacity as Agent for Lenders ("Agent").

                                    RECITALS

     WHEREAS, Lenders have agreed to extend a revolving credit facility to
Borrower, on certain terms and conditions; and

     WHEREAS, Agent has agreed to serve as administrative and collateral agent,
on certain terms and conditions, with respect to the credit facility to be
extended to Borrower; and

     WHEREAS, Borrower, Lenders and Agent wish to provide for the terms and
conditions of the revolving credit facility to be granted to Borrower and the
terms and conditions of Agent's service as administrative and collateral agent
hereunder;

     NOW, THEREFORE, as an inducement to cause Lenders to extend credit to
Borrower; as an inducement for Agent to serve under this Agreement; and for
other valuable consideration, the receipt and sufficiency of which are
acknowledged, it is agreed as follows:

                                I.   DEFINITIONS

      1.1  Terms Defined in This Agreement.  As used below in this Agreement,
the following capitalized terms shall have the following meanings, unless the
context expressly requires otherwise:

     "ACQUIRED DEBT" means Debt that is outstanding as of the date of
determination and which was previously a loan obligation or a Capital Lease of
an Acquired Practice at the time the Practice was acquired by a Borrower Entity;
provided, however, if any portion of such Debt is subject to the unqualified and
noncontingent written obligation of a Provider to repay the Debt, with interest,
in accordance with its terms, then "Acquired Debt" shall only include the
portion of such Debt that is not subject to the Provider's obligation of
repayment.

     "ACQUIRED PRACTICE" means a Practice that is either (i) owned by a Borrower
Entity as of the date hereof or (ii) acquired by a Borrower Entity after the
date hereof through a Permitted Acquisition.

     "ACQUISITION EBITDA" means, with respect to a Practice acquired by a
Borrower Entity and covered by a Service Agreement, the pro forma income to the
Borrower Entities that would have arisen under the applicable Service Agreement
if the Service
<PAGE>

Agreement had been in effect, and the acquisition had occurred, prior to the
beginning of the relevant financial period, with Service Agreement income
determined based upon the actual financial performance of the Acquired Practice
over the relevant financial period, as adjusted only to reflect changes in
payments to owner or stockholder Providers (whether characterized as
professional fees or management fees) and demonstrable reductions in expenses
arising under Borrower's established programs for the purchase of services and
supplies. Acquisition EBITDA of a Practice must be based upon financial
information that Agent regards as accurate and reliable (which is confirmed as
to Acquired Practices owned by Borrower Entities as of the date hereof).  In
assessing the accuracy and reliability of financial information for this
purpose, unqualified audited financial statements prepared by a regional or
national accounting firm shall be acceptable in any case, and shall be required
in the cases of acquisitions (i) of publicly held companies or their assets, and
(ii) in which the Acquisition EBITDA of the target would exceed fifteen percent
(15%) of the Consolidated Adjusted EBITDA of the Borrower Entities for the
previous fiscal year.  If audited financial statements are not required to be
provided under the preceding sentence, other sources of financial information
will be considered for approval on a case-by-case basis, in Agent's reasonable
discretion.

     "AFFILIATE" means, with respect to any Person, another Person that,
directly or indirectly, (i) has an equity interest in that Person in an amount
of more than twenty percent (20%) of such Person, (ii) has common ownership with
that Person, where the common owner owns more than twenty percent (20%) of each
Person so affiliated, (iii) Controls that Person, or (iv) shares common Control
with that Person.

     "AGENT" means NationsBank of Tennessee, N.A., in its capacity as described
in Article IX of this Agreement, its lawful corporate successors and any
successor agent appointed pursuant to Article IX hereof.

hereto), as the same may be amended from time to time.

     "ALTERNATE BASE RATE" means the greater of (i) the Federal Funds Rate plus
one-half percent (1/2%), and (ii) the rate announced by Agent as its "prime
rate" (which rate is not necessarily the lowest rate offered on any particular
type of loan), in each case as it may change from time to time.

     "APPLICABLE COMMITMENT FEE," "APPLICABLE LIBO RATE MARGIN" and "APPLICABLE
BASE RATE MARGIN" mean, with respect to Loans advanced under and the commitment
fee respecting the Revolving Credit Loan, (i) until the earlier of the first

          designated Interest Period. Each Borrowing Notice shall irrevocably
          obligate Borrower to accept the Loan requested thereby. Borrowing
          Notices shall be in the form of Exhibit 2.5.1(b) hereto or such other
          form as Agent may from time to time reasonably require.

                 2.5.1(c) Funding of Loans.  Lenders shall fund their respective
          portions of requested Loans on the next following Banking Day after
          the Banking Day (determined with a cutoff of 11:00 a.m. Charlotte,
          North Carolina time, as provided in the definition thereof) of

                                       19
<PAGE>

          Agent's receipt of the Borrowing Notice, in the case of Base Rate
          Loans, and on the third (3rd) Banking Day following the Banking Day of
          Agent's receipt of the Borrowing Notice, in the case of LIBOR Loans.
          All funds shall be disbursed directly into an account maintained by
          Borrower with Agent. Borrower agrees that if any Lender elects to fund
          any requested Loan(s) sooner after requested than is required
          hereunder, the Lender may nevertheless use the entire response period
          allowed hereunder upon receipt of any subsequent request, at the
          Lender's sole option.

                 2.5.1(d) Base Rate Loan Limitations. Individual Base Rate Loans
          shall be in the minimum amount of One Million and No/100 Dollars
          ($1,000,000.00) each and in multiples of One Million and No/100
          Dollars ($1,000,000.00).

                 2.5.1(e) LIBOR Loan Limitations. Individual LIBOR Loans shall
          be in the minimum amount of Three Million and No/100 Dollars
          ($3,000,000.00) each and shall be requested in increments of One
          Million and No/100 Dollars ($1,000,000.00). No more than six (6) LIBOR
          Loans may be outstanding under the Revolving Credit Loan.

                 2.5.1(f) Additional Limitation on LIBOR Interest Periods.
          Notwithstanding anything to the contrary in this Agreement, if an
          Unmatured Default or an Event of Default shall have occurred and be
          continuing, no additional LIBOR Loans may be created or continued and
          no Base Rate Loan may be converted into a LIBOR Loan.

     2.5.2 Conversion of Loans.  Borrower shall have the right, on prior notice
to Agent made by telephone, subject to such security procedures as Agent may
require from time to time (provided that all such telephonic notices shall be
confirmed by written Borrowing Notices within one (1) Business Day), which
notice shall be given three (3) Banking Days (determined with a cutoff of 11:00
a.m. Charlotte, North Carolina time, as provided in the definition thereof)
prior to the date of any requested conversion, to convert any Base Rate Loan or
LIBOR Loan into a Loan of another type, or to continue any LIBOR Loan for
another Interest Period, subject in each case to the following:

                 2.5.2(a) Application of Loans. Each conversion shall be
          effected by applying the proceeds of the new LIBOR Loan and/or Base
          Rate Loan, as the case may be, to the Loan (or portion thereof) being
          converted.

                 2.5.2(b) Notices of Conversions.  Each notice pursuant to this
          2.5.2(b) shall be irrevocable and shall refer to this Agreement and

                                       20
<PAGE>

          specify the identity and principal amount of the particular Loan that
          Borrower requests be converted or continued; if such notice requests
          conversion, the date of such conversion (which shall be a Business
          Day); and if a Loan is to be converted to a LIBOR Loan or a LIBOR Loan
          is to be continued, the Interest Period with respect thereto. No LIBOR
          Loan shall be converted at any time other than at the end of the
          Interest Period applicable thereto, except in accordance with Section
          2.11 hereof. Conversion notices shall be in the form attached as
          Exhibit 2.5.1(b) hereto.

     2.5.3 Absence of Election. In the event that Borrower shall not give notice
to continue any LIBOR Loan for a subsequent period, such LIBOR Loan (unless
repaid) shall automatically be converted into a Base Rate Loan. If Borrower
fails to specify in any Borrowing Notice the type of borrowing or, in the case
of a LIBOR Loan, the applicable Interest Period, Borrower will be deemed to have
requested a Base Rate Loan.  If Agent reasonably believes that any failure by
Borrower to specify the type of borrowing or the applicable Interest Period
shall have resulted from failure of communications equipment or clerical error,
then prior to funding any such borrowing Agent shall use reasonable efforts to
obtain confirmation from Borrower of the contents of such Borrowing Notice;
provided, however, in the absence of prompt confirmation by Borrower which
specifies the type of borrowing and/or the applicable Interest Period, Borrower
will be deemed to have requested a Base Rate Loan.  Notwithstanding anything to
the contrary contained above, if an Event of Default shall have occurred and be
continuing, no LIBOR Loan may be continued and no Base Rate Loan may be
converted into a LIBOR Loan.

     2.5.4 Implied Representations Upon Request for Loan.  Upon making any
request for any Loan, Borrower shall be deemed to have warranted to Agent and
Lenders that all conditions to funding set forth in Article III hereof are
satisfied and that all warranties made herein are true and shall be true as of
the funding of the requested Loan, subject to exception for warranties that
speak to a specific date or for which the underlying facts have changed pursuant
to transactions permitted under this Agreement, as provided in Exhibit 2.5.1(b)
hereto.

     2.5.5 Advance Not Waiver.  Any Lender's making of any Loan that it is not
obligated to make under any provision of Article III hereof or any other
provision hereof shall not be construed as a waiver of such Lender's right to
withhold future Loans, declare an Event of Default, or otherwise demand strict
compliance with this Agreement, acting through Agent as permitted by the terms
hereof.

                                       21

     2.5.6  Draws by Debit Memorandum.  Agent may cause Lenders to draw
amounts that may be available under the Revolving Credit Loan to pay any
Obligation that is not otherwise timely paid.

2.6  Interest.  Interest shall accrue on each Loan as follows:

     2.6.1 Base Rate Loans.  Interest shall accrue on each Base Rate Loan at an
annual rate equal to the Alternate Base Rate plus the Applicable Base Rate
Margin, said rate to change contemporaneously with any change in the Alternate
Base Rate.

     2.6.2 LIBOR Loans.  Interest shall accrue on each LIBOR Loan at a rate
equal to the LIBO Rate for the selected Interest Period plus the Applicable LIBO
Rate Margin.

     2.6.3 Additional Interest on LIBOR Loans.  In addition to the interest
described above, Borrower shall pay to any Lender, if and so long as such Lender
shall be required under regulations of the Board of Governors of the Federal
Reserve System to maintain reserves with respect to liabilities or assets
consisting of or including LIBOR Liabilities, additional interest on the unpaid
principal amount of each LIBOR Loan, from the date of such advance until said
principal amount is paid in full, at an interest rate per annum equal at all
times to the remainder obtained by subtracting (i) the LIBO Rate for the
Interest Period from (ii) the rate obtained by dividing the LIBO Rate by a
percentage equal to 100% minus the LIBO Rate Reserve Percentage for such
Interest Period.  This additional interest shall be payable on each date on
which interest is payable and shall be effective only after the affected Lender
(or Agent on behalf of all Lenders) gives written notice thereof to Borrower.
The amount of additional interest shall be determined by each Lender, who shall
notify Borrower and Agent thereof and whose determination shall be conclusive,
absent manifest error.

     2.6.4 Calculation of Interest.  Interest for both Base Rate Loans and LIBOR
Loans shall be computed on the basis of a 360-day year counting the actual
number of days elapsed.  Interest shall accrue on the Business Day a Loan is
extended and shall accrue through the Business Day of payment if payment is
received before 11:00 a.m. Charlotte, North Carolina time and through the next
following Business Day if received after that time.

     2.6.5 Default Rate.  Notwithstanding the foregoing, upon the occurrence of
an Event of Default and during the continuation of such Event of Default,
interest shall be charged at the Default Rate, regardless of whether Lenders
have elected to exercise any other remedies available to Lenders, including,
without limitation, acceleration of the maturity of the outstanding principal of
the Revolving Credit Loan.

                                       22
<PAGE>

          2.6.6  Payment of Interest.  Interest for Base Rate Loans and LIBOR
 Loans shall be due and payable in arrears, without notice, on each Interest
 Payment Date.

          2.6.7 Usury Savings Provision. It is the intention of the parties that
 all charges under or in connection with this Agreement and the Obligations,
 however denominated, and including (without limitation) all interest,
 commitment fees, late charges and loan charges, shall be limited to the Maximum
 Lawful Amount. Such charges hereunder shall be characterized and all provisions
 of the Loan Documents shall be construed as to uphold the validity of charges
 provided for therein to the fullest possible extent. Additionally, all charges
 hereunder shall be spread over the full permitted term of the Obligations for
 the purpose of determining the effective rate thereof to the fullest possible
 extent, without regard to prepayment of or the right to prepay the Obligations.
 If for any reason whatsoever, however, any charges paid or contracted to be
 paid in respect of the Obligations shall exceed the Maximum Lawful Amount,
 then, without any specific action by Lenders, Agent or Borrower, the obligation
 to pay such interest and/or other charges shall be reduced to the Maximum
 Lawful Amount in effect from time to time, and any amounts collected by Lenders
 that exceed the Maximum Lawful Amount shall be applied to the reduction of the
 principal balance of the Obligations and/or refunded to Borrower so that at no
 time shall the interest or loan charges paid or payable in respect of the
 Obligations exceed the Maximum Lawful Amount. This provision shall control
 every other provision herein and in any and all other agreements and
 instruments now existing or hereafter arising between Borrower and Lenders with
 respect to the Obligations.

      2.7  Alternate Rate of Interest if LIBOR Unavailable.  In the event, and
on each occasion, that on the date of commencement of any Interest Period for a
LIBOR Loan, a Lender shall have determined (i) that dollar deposits in the
amount of the requested principal amount of such LIBOR Loan are not generally
available in the London Interbank Market; (ii) that the rate at which such
dollar deposits are being offered will not adequately and fairly reflect the
cost to the Lender of making or maintaining such LIBOR Loan during such Interest
Period; or (iii) that reasonable means do not exist for ascertaining the LIBO
Rate, the Lender shall, as soon as practicable thereafter, give written or
telephonic notice of such determination to Borrower and Agent.  In the event of
any such determination, any request by Borrower for a LIBOR Loan under this
Agreement shall, until the circumstances giving rise to such notice no longer
exist, be deemed to be a request for a Base Rate Loan. Each determination by a
Lender hereunder shall be conclusive absent manifest error.

      2.8  Change in Circumstances.

           2.8.1 Imposition of Requirements. Notwithstanding any other provision
herein, if after the date of this Agreement any change in applicable

                                       23
<PAGE>

Laws or in the interpretation or administration thereof by any Governmental
Authority charged with the interpretation or administration thereof (whether or
not having the force of Law) shall change the basis of taxation of payments to a
Lender under any LIBOR Loan made by the Lender or any other fees or amounts
payable hereunder (other than taxes imposed on the overall net income, gross
receipts or added value of a Lender by the country in which the Lender is
located, or by the jurisdiction in which a Lender has its principal office, or
by any political subdivision or taxing authority therein), or shall impose,
modify or deem applicable any reserve requirement, special deposit, insurance
charge (including FDIC insurance on LIBOR Liabilities) or similar requirement
against assets of, deposits with or for the account of, or credit extended by, a
Lender or shall impose on a Lender or the London Interbank Market any other
condition affecting this Agreement or LIBOR Loans made by a Lender, and the
result of any of the foregoing shall be to increase the cost to the Lender of
making or maintaining its LIBOR Loan or to reduce the amount of any sum received
or receivable by a Lender hereunder (whether of principal, interest or
otherwise) in respect thereof by an amount deemed by the affected Lender to be
material, then Borrower will pay to such Lender such additional amount or
amounts as will compensate the Lender for such additional costs of reduction.

     2.8.2 Other Changes.  If either (i) the introduction of, or any change in,
or in the interpretation of, any United States or foreign Law; or (ii)
compliance with any directive, guidelines or request from any central bank or
other United States or foreign Governmental Authority (whether or not having the
force of law) promulgated or made after the date hereof, affects or would affect
the amount of capital required or expected to be maintained by a Lender (or any
lending office of a Lender) or any corporation directly or indirectly owning or
controlling a Lender (or any lending office of a Lender) based upon the
existence of this Agreement, and the Lender shall have determined that such
introduction, change or compliance has or would have the effect of reducing the
rate of return on the Lender's capital or on the capital of such owning or
controlling corporation as a consequence of its obligations hereunder (including
its commitment) to a level below that which the Lender or such owning or
controlling corporation could have achieved but for such introduction, change or
compliance (after taking into account that Lender's policies or the policies of
such owning or controlling corporation, as the case may be, regarding capital
adequacy) by an amount deemed by the Lender (in its sole discretion) to be
material, then, from time to time, Borrower shall pay to the Lender such
additional amount or amounts as will compensate the Lender for such reduction
attributable to making, funding and maintaining its commitment and Loans
hereunder.

     2.8.3 Computation of Amounts.  A certificate of a Lender setting forth the
basis and method of computation of such amount or amounts

                                       24
<PAGE>

specified in Sections 2.8.1 and 2.8.2 hereof as shall be necessary to compensate
the Lender (or its participating banks) as specified above, as the case may be,
shall be delivered to Borrower and shall be conclusive absent manifest error;
provided however, that Borrower shall be responsible for compliance herewith and
the payment of increased costs only to the extent that (i) any change in Laws
giving rise to increased costs occurs after the date of this Agreement; (ii)
such increased costs are imposed by the Lender on all other Borrowers similarly
situated with Borrower; and (iii) the Lender gives notice of the change giving
rise to increased costs within ninety (90) Business Days after the Lender has,
or with reasonable diligence should have had, knowledge of the change, or else
Lender can only collect costs from and after the date of the notice. Subject to
the foregoing, Borrower shall pay the affected Lender the amount shown as due on
any such certificate within ten (10) Business Days after its receipt of such
certificate.

     2.8.4  No Duty to Contest.  The protection of this Section 2.8 shall be
available to a Lender regardless of any possible contention of invalidity or
inapplicability of the Law or condition that shall have been imposed.  Should a
Lender assess any charge to Borrower under this Section 2.8, and provided that
Borrower pays the assessment to the Lender,  Borrower may within ninety (90)
days after receiving notice of such assessment undertake, at Borrower's own
expense, any contest of the matters giving rise to the charge that may, in the
opinion of Borrower's independent counsel issued to the affected Lender, and
concurred in by counsel to the Lender, have a reasonable chance of success,
provided further that the contest would not require the assertion of any
position contrary to a position taken by the Lender generally with taxing
authorities or any other involved parties and that there does not exist any
other circumstance that would disadvantage the Lender in the event of such
contest, as the affected Lender may determine in its discretion.  The affected
Lender shall offer reasonable participation to Borrower for the purpose of
enabling Borrower to pursue the contest of such issue, with all expenses,
including fees and expenses of the affected Lender's counsel, to be paid by
Borrower.

     2.8.5 Replacement of Lenders Under Certain Circumstances.   If any specific
additional charge is assessed under Sections 2.6.3, 2.7 or 2.8 hereof by less
than a majority in number of the Lenders, Borrower shall be entitled to request
of Agent that the Lender(s) assessing such additional charge be replaced as
Lenders hereunder by other financial institutions proposed by Borrower who do
not then assess such additional charge.  Agent shall arrange the appointment of
such replacement Lender(s), who must be acceptable to both Agent and Borrower in
their reasonable discretion.  The appointment of such new Lender(s) shall be
accomplished in accordance with the other provisions of this Agreement and
Borrower shall pay the applicable fee to Agent for the transfer of the interest
of the replaced Lender(s).

                                       25
<PAGE>

      2.9  Change in Legality of LIBOR Loans.  Notwithstanding anything to the
contrary herein contained, if any change in any Law or in interpretation thereof
by any Governmental Authority charged with the administration or interpretation
thereof shall make it unlawful for a Lender to make or maintain any LIBOR Loan
or to give effect to its obligations as contemplated hereby, then, by written
notice to Borrower, the Lender may (i) declare that LIBOR Loans will not
thereafter be made by the Lender hereunder, whereupon Borrower shall be
prohibited from requesting LIBOR Loans from the Lender hereunder unless such
declaration is subsequently withdrawn; and (ii) require that all outstanding
LIBOR Loans made by it be converted to Base Rate Loans, in which event (a) all
such LIBOR Loans shall be automatically converted to Base Rate Loans (but
without imposition of any additional charge that would normally become due under
Section 2.11 hereof) as of the effective date of such notice, and (b) all
payments and prepayments of principal that would otherwise have been applied to
repay the converted LIBOR Loans shall instead be applied to repay the Base Rate
Loans resulting from the conversion of such LIBOR Loans. Under such
circumstances, a borrowing request for a LIBOR Loan shall be regarded, as to the
Lender who has given notice under this Section 2.9, a request for a Base Rate
Loan, and as to all other Lenders, it shall be regarded as a request for a LIBOR
Loan. For purposes of this Section 2.9, a notice to Borrower by the Lender
pursuant to (a) above shall be effective, if lawful, on the last day of the then
current Interest Period; in all other cases, such notice shall be effective on
the date of receipt by Borrower.

      2.10 Principal Repayment.  All remaining principal outstanding under the
Revolving Credit Loan shall become due on the Maturity Date or the earlier
acceleration of the Revolving Credit Loan in accordance with the terms of this
Agreement.

      2.11 Prepayment of LIBOR Loans.

           2.11.1 Notice of LIBOR Loan Prepayment. Borrower may, upon three (3)
      Banking Days' prior written notice to Agent (with a Banking Day cutoff of
      11:00 a.m. Charlotte, North Carolina time, as provided in the definition
      thereof), and upon payment of all applicable premiums set forth in Section
      2.11.3 hereof, prepay any outstanding LIBOR Loans prior to any Interest
      Payment Date for such LIBOR Loans, in whole or in part. Each notice of
      prepayment of any LIBOR Loan shall specify the date and amount of such
      prepayment and shall be irrevocable.

           2.11.2 Amount of LIBOR Loan Prepayment. Each partial prepayment of
      any LIBOR Loan shall be in an aggregate principal amount which is the
      lesser of (i) the then outstanding principal balance of the one or more
      LIBOR Loans to be prepaid, or (ii) Three Million and No/100 Dollars
      ($3,000,000.00) or a larger integral multiple of One Million and No/100
      Dollars ($1,000,000.00). Interest on the amount prepaid accrued to the
      prepayment date shall be paid on such date.

                                       26
<PAGE>

               2.11.3 LIBOR Loan Breakage Costs. Borrower shall indemnify,
      defend and hold harmless each Lender against any loss or expense that a
      Lender may incur in connection with the prepayment of a LIBOR Loan, the
      Borrower's failure to borrow or to pay when it stated it would do so,
      including, but not limited to, the fees or charges customarily included in
      "breakage costs" that may result to a Lender from the early repayment of a
      LIBOR Liability, which costs may be calculated by a Lender as though
      Borrower's prepayment had been match-funded with a corresponding LIBOR
      Liability, whether or not the Lender manages its LIBOR Liabilities on a
      loan-by-loan basis. Additionally, upon prepayment of any LIBOR Loan on a
      date other than the relevant Interest Payment Date for such borrowing,
      Borrower shall pay to Lenders, in addition to all other payments then due
      and owing Lenders, premiums which shall be equal to an amount, if any,
      reasonably determined by Agent to be the difference between the rate of
      interest then applicable to the relevant LIBOR Loan and the yield Lenders
      would receive upon reinvestment of so much of the relevant LIBOR Loans as
      is prepaid for the remainder of the term of the relevant LIBOR Loan or
      Loans. Anything in this Section 2.11.3 to the contrary notwithstanding,
      the premiums payable upon any such prepayment shall not exceed the amount,
      if any, determined by Agent to be the difference between the rate of
      interest then applicable to the relevant LIBOR Loan and the yield that
      Lenders could receive upon reinvestment in the "Floor Reinvestment" of so
      much of the relevant LIBOR Loan as is prepaid for the remainder of the
      term of the relevant LIBOR Loan. For purposes hereof, "Floor Reinvestment"
      shall mean an investment for the time period from the date of such
      prepayment to the end of the relevant Interest Period applicable to such
      LIBOR Loan at an interest rate per annum equal to the Federal Funds Rate
      on the date of such prepayment. All determinations, estimates,
      assumptions, allocations and the like required for the determination of
      such premiums shall be made by Agent in good faith and shall be presumed
      correct absent manifest error.

      2.12 Prepayment of Base Rate Loans.  Borrower may at any time prepay any
outstanding Base Rate Loans prior to the Maturity Date in whole or in part
without premium or penalty upon at least one Business Day's prior notice to
Agent.  All such prepayments shall be made in minimum amounts of Three Million
and No/100 Dollars ($3,000,000.00) and in increments of One Million and No/100
Dollars ($1,000,000.00) each.

      2.13 Reduction of Commitment.  Borrower may prospectively and permanently
reduce the Commitment by giving Agent written notice of a reduction to be
effective on a date certain no earlier than ten (10) Business Days after the
notice is received by Agent.  The principal balance of the Revolving Credit Loan
shall be reduced, if necessary, on the effective date of the reduction in
accordance with the notice.  Reductions shall be shared by Lenders Pro Rata.  If
it is necessary to prepay any LIBOR Loan to accommodate the requested reduction,
Borrower shall be liable for all costs provided for elsewhere in this Agreement.
All reductions shall be in amounts of at least Three Million

                                       27
<PAGE>

and No/100 Dollars ($3,000,000.00) and shall be made in increments of One
Million and No/100 Dollars ($1,000,000.00).

      2.14 Periodic Commitment Fee Based on Use of Facilities.  Borrower shall
pay to Agent for distribution to Lenders Pro Rata an additional commitment fee
for the unused portion of the Revolving Credit Loan.  This fee shall be
determined by applying the Applicable Commitment Fee (applied on the basis of a
360-day year) to the average daily unused balance of the Revolving Credit Loan.
The commitment fee shall be paid in arrears on each Interest Payment Date
applicable to Base Rate Loans.  This commitment fee is not refundable.  As
provided in Section 2.15.2 hereof, all outstanding Letter of Credit Liabilities
shall be treated as outstanding Loans for the purpose of determining the nonuse
fee.

      2.15 Letters of Credit.  Subject to the terms and conditions of this
Agreement, Lenders' respective Commitments for the Revolving Credit Loan may be
utilized, upon the request of Borrower, for the issuance by the Issuing Bank of
standby or commercial letters of credit (the "Letters of Credit") for the
account of Borrower for uses that would be permitted for the Revolving Credit
Loan; provided that in no event shall (i) the aggregate amount of all stated and
undrawn amounts under Letters of Credit (the "Letter of Credit Liabilities"),
together with the aggregate principal amount of the Loans advanced under the
Revolving Credit Loan, exceed the amount stated in Section 2.1 hereof, (ii) the
outstanding aggregate amount of all Letter of Credit Liabilities exceed Five
Million and No/100 Dollars ($5,000,000.00), or (iii) the expiration date of any
Letter of Credit extend beyond the Maturity Date applicable to the Revolving
Credit Loan.  The following additional provisions shall apply to Letters of
Credit:

            2.15.1 Procedure for Issuance. Borrower shall give Agent at least
      three (3) Business Days' irrevocable prior notice (effective upon receipt)
      specifying the Business Day (which shall be no later than thirty (30) days
      preceding the Maturity Date) each Letter of Credit is to be issued and
      describing in reasonable detail the proposed terms of such Letter of
      Credit (including its beneficiary) and the nature of the transactions or
      obligations proposed to be supported. Borrower shall be the account party
      for each Letter of Credit, including Letters of Credit issuable to a
      beneficiary having a claim or potential claim against a Subsidiary of
      Borrower.

            2.15.2 Participation Among Lenders. On each day during the period
      commencing with the issuance by the Issuing Bank of any Letter of Credit
      and until such Letter of Credit shall have expired or been terminated or,
      if drawn upon, until the resulting obligations of reimbursement (the
      "Reimbursement Obligations") have been satisfied in full by Borrower
      (whether by a borrowing under this Agreement or otherwise), the Commitment
      of each Lender shall be deemed to be utilized for all purposes of this
      Agreement (including, but not limited to, the calculation of availability
      and of the nonuse fee) in an amount equal to such Lender's Pro Rata Share
      of the Letter of Credit Liabilities associated with such Letter of Credit.
      Each Lender (other than the Issuing

                                       28
<PAGE>

      Bank) agrees that, upon the issuance of any Letter of Credit, it shall
      automatically be deemed to have acquired a participation in the Issuing
      Bank's liability under such Letter of Credit in an amount equal to such
      Lender's Pro Rata Share of such liability, and each Lender (other than the
      Issuing Bank) thereby shall absolutely, unconditionally and irrevocably
      assume, as primary obligor and not as surety, and shall be unconditionally
      obligated to the Issuing Bank to pay and discharge when due, its Pro Rata
      Share of the Issuing Bank's liability under such Letter of Credit.

           2.15.3 Reimbursement Obligation. Upon receipt from the beneficiary of
      any Letter of Credit of any demand for payment under such Letter of
      Credit, the Issuing Bank shall promptly notify Borrower of the amount to
      be paid by the Issuing Bank as a result of such demand and the date on
      which payment is to be made by the Issuing Bank to such beneficiary in
      respect of such demand. Borrower hereby unconditionally agrees to pay and
      reimburse Agent for the account of the Issuing Bank and the other Lenders
      Pro Rata with respect to the amount of each demand for payment under such
      Letter of Credit at or prior to the date on which payment is to be made by
      the Issuing Bank to the beneficiary under such Letter of Credit, without
      presentment, demand, protest or other formalities of any kind. Any amounts
      not so paid or borrowed as set forth in Section 2.15.4 below shall bear
      interest at the Default Rate applicable to Base Rate Loans.

           2.15.4 Means of Reimbursement. Forthwith upon its receipt of a notice
      referred to in Section 2.15.3 hereof, Borrower shall advise Agent whether
      or not Borrower intends to obtain a Loan to finance its obligation to
      reimburse the Issuing Bank for the amount of the related demand for
      payment and, if it does, submit a notice of such borrowing as provided in
      this Agreement. In the event that Borrower fails to so advise Agent, and
      if Borrower fails to reimburse the Issuing Bank for a demand for payment
      under a Letter of Credit by the date of such payment, Agent shall give
      each Lender prompt notice of the amount of the demand for payment,
      specifying such Lender's Pro Rata Share of the amount of the related
      demand for payment, and Borrower shall be deemed in default hereunder for
      breaching Section 2.15.3 above.

           2.15.5 Payments by Lenders. Each Lender (other than the Issuing Bank)
      shall pay to Agent for the account of the Issuing Bank in Dollars and in
      immediately available funds, such Lender's Pro Rata Share of any payment
      under a Letter of Credit upon notice by Agent to such Lender requesting
      such payment and specifying such amount as provided in Section 2.15.4.
      Each such Lender's obligation to make such payments to Agent for the
      account of the Issuing Bank under this Section 2.15.5, and the Issuing
      Bank's right to receive the same, shall be absolute and unconditional and
      shall not be affected by any circumstance whatsoever, including the
      failure of any other Lender to make its

                                       29
<PAGE>

      payment under this Section 2.15.5, the financial condition of Borrower,
      the existence of any Unmatured Default or Event of Default or the
      termination of the Commitments. Each such payment to the Issuing Bank
      shall be made without any offset, abatement, withholding or reduction
      whatsoever, EVEN IN THE PRESENCE OF ORDINARY NEGLIGENCE ON THE PART OF THE
      ISSUING BANK; provided, nothing contained in the foregoing shall limit the
      Issuing Bank's liability for its gross negligence or willful misconduct in
      improperly honoring a draft drawn under a Letter of Credit.

           2.15.6 Settlement Among Lenders. Upon the making of each payment by a
      Lender to the Issuing Bank pursuant to Section 2.15.5 above in respect of
      any Letter of Credit, such Lender shall, automatically and without any
      further action on the part of Agent, the Issuing Bank or such Lender,
      acquire (i) a participation in an amount equal to such payment in the
      Reimbursement Obligation owing to the Issuing Bank by Borrower under this
      Agreement and under the Letter of Credit Documents relating to such Letter
      of Credit and (ii) a participation in a percentage equal to such Lender's
      Pro Rata Share in any interest or other amounts payable by Borrower under
      such Letter of Credit Documents and the other Loan Documents in respect of
      such Reimbursement Obligation. Upon receipt by the Issuing Bank from or
      for the account of Borrower of any payment in respect of any Reimbursement
      Obligation or any such interest or other amount (including by way of set-
      off or application of proceeds of any collateral security) the Issuing
      Bank shall promptly pay to Agent for the account of each Lender who shall
      have previously assumed a participation in such payment under clause (ii)
      above, such Lender's Pro Rata Share of such payment, each such payment by
      the Issuing Bank to be made in the same money and funds in which received
      by the Issuing Bank. In the event any payment received by the Issuing Bank
      and so paid to Lenders is rescinded or must otherwise be returned by the
      Issuing Bank, each Lender shall, upon the request of the Issuing Bank
      (through Agent), repay to the Issuing Bank (through Agent) the amount of
      such payment paid to such Lender, with interest at the rate specified in
      Section 2.15.10.

      Letter of Credit to and including the date such Letter of Credit is drawn
      in full, expires or is terminated (such fee to be non-refundable, to be
      paid in arrears on the first day of each calendar quarter and on the
      Maturity Date applicable to the Revolving Credit Loan and to be
      calculated, for any day, after giving effect to any payments made under
      such Letter of Credit on such day) in an amount equal to the Applicable
      LIBO Rate Margin(s) in effect during the relevant period (or such margin
      plus two percentage points (2%), upon and during the continuation of an
      Event of Default hereunder). All calculations of Letter of

      upon the issuance thereof.

      from time to time, the Issuing Bank shall deliver any information
      reasonably requested by such Lender with respect to each Letter of Credit
      then outstanding.

      Issuing Bank of each Letter of Credit shall be subject, in addition to the
      conditions precedent set forth in Article III hereof, to the conditions

      such terms and support such transactions as shall be satisfactory to the
      Issuing Bank consistent with its then current practices and procedures
      with respect to letters of credit of the same type and (ii) Borrower shall
      have executed and delivered such applications, agreements and other
      instruments relating to such Letter of Credit as the Issuing Bank shall

      procedures with respect to letters of credit of the same type; provided
      that in the event of any conflict between any such application, agreement
      or other instrument and the provisions of this Agreement, the provisions
      of this Agreement shall control. Without limiting the foregoing, it is
      agreed that (i) an "Event of Default" under any reimbursement agreement
      respecting a Letter of Credit shall be deemed to mean an Event of Default
      under this Agreement, and (ii) no Borrower Entity shall be required to
      provide any collateral to secure its obligations regarding any Letter of
      Credit except as required herein.

          2.15.10 Payments Among Lenders. In the event that any Lender fails to

                      IV.  REPRESENTATIONS AND WARRANTIES

     Borrower represents and warrants to Lenders and Agent that as of the
Closing Date:

      4.1  Capacity.  Each Borrower Entity is a corporation or other entity as
set forth in Schedule 1.1 hereof, and is duly organized, validly existing and in
good standing under the laws of the state of its domicile as set forth in
Schedule 1.1.  Each Borrower Entity is qualified or authorized to do business in
all jurisdictions in which its ownership of property or conduct of business
requires such qualification or authorization or where the failure to be so
qualified or authorized would not have a Material Adverse Effect.  Each Borrower
Entity has the power and authority to own its Properties and to carry on its
business as now being conducted and as proposed to be conducted after the
execution hereof, to execute and deliver this Agreement and the other Loan
Documents, and to perform its obligations hereunder and under the other Loan
Documents.

      4.2  Authorization.  The execution, delivery and performance of this
Agreement and the other Loan Documents by each Borrower Entity executing such
documents has been duly authorized by all requisite action.

      4.3  Binding Obligations.  This Agreement is and the other Loan Documents,
when executed and delivered to Agent and Lenders, will be, legal, valid and
binding upon each Borrower Entity who is a party thereto, enforceable in
accordance with its respective terms, subject only to principles of equity and
laws applicable to creditors generally, including bankruptcy laws.

      4.4  No Conflicting Law or Agreement.  The execution, delivery and
performance of this Agreement and the other Loan Documents by each Borrower
Entity does not constitute a breach of or default under, and will not violate or
conflict with, any provisions of the corporate charter or other constituent
documents of a Borrower Entity; any contract, financing agreement, lease, or
other agreement to which a Borrower Entity is a party or by which its Properties
may be affected, the violation of which would have a Material Adverse Effect; or
any Law to which a Borrower Entity is subject or by which its Properties may be
affected, the violation of which would have a Material Adverse Effect; nor will
the same result in the creation or imposition of any Encumbrance upon any
Property of any Borrower Entity, other than those contemplated by the Loan
Documents.

      4.5  No Consent Required. The execution, delivery, and performance of this
Agreement and the other Loan Documents by the Borrower Entities do not require
the consent or approval of or the giving of notice to any Person except for
those consents which

                                       39
<PAGE>

have been duly obtained and are in full force and effect on the date hereof and
others, if any, which by their omission would not result in a Material Adverse
Effect.

      4.6  Financial Statements.  The Financial Statements are complete and
correct, have been prepared in accordance with GAAP, and present fairly the
financial condition and results of operations of the Borrower Entities as of the
date and for the period stated therein, subject to year-end adjustments.  No
Material Adverse Change has occurred since the date of the Financial Statements.
Borrower acknowledges that Lenders have advanced (or shall advance) the
Revolving Credit Loan in reliance upon the Financial Statements.

      4.7  Fiscal Year.  Borrower's fiscal year ends on December 31 of each
year.

      4.8  Litigation.  Except as disclosed on Schedule 4.8 hereto, (i) there is
no litigation, arbitration, legal or administrative proceeding, tax audit,
investigation, or other action or proceeding of any nature pending against any
Borrower Entity or any of its Properties which, if adversely determined, would
likely have a Material Adverse Effect, and (ii) there is no litigation,
arbitration, legal or administrative proceeding, tax audit, investigation, or
other action or proceeding of any nature threatened in writing against a
Borrower Entity which, if adversely determined, would have a Material Adverse
Effect.  No Borrower Entity is subject to any outstanding court, arbitral or
administrative order, writ or injunction. To the best of Borrower's knowledge,
information and belief, no facts exist under which third parties have unasserted
claims against any Borrower Entity which, if adversely determined, would have a
Material Adverse Effect.

      4.9  Taxes; Governmental Charges.  Each Borrower Entity has filed or
caused to be filed or has lawfully extended the deadline for filing all tax
returns and reports required to be filed, other than those which, if not filed,
would not have a Material Adverse Effect.  Each Borrower Entity has paid, or
made adequate provision for the payment of, all Taxes that have or may have
become due pursuant to such returns or otherwise, or pursuant to any assessment
received by it, except such Taxes, if any, as are being contested in good faith
by appropriate proceedings and for which adequate reserves have been provided.
To the best of Borrower's knowledge, there is no proposed material tax
assessment against any Borrower Entity.  No extension of time for the assessment
of federal, state or local taxes of any Borrower Entity is in effect or has been
requested.  Each Borrower Entity has timely made all required remittances of
withholding deposits and other assessments against payroll expenditures except
for matters that would not have a Material Adverse Effect.


      4.10 Title to Properties.  Each Borrower Entity has good and marketable
title to its Properties, free and clear of all Encumbrances except for Permitted
Encumbrances except for matters that would not have a Material Adverse Effect.

      4.11 No Default.  No Borrower Entity is in default in any respect that
affects its business, Properties, operations, or condition, financial or
otherwise, under any

                                       40
<PAGE>

indenture, mortgage, deed of trust, obligation to equity holders, credit
agreement, note, agreement, lease, sale agreement or other instrument to which
any Borrower Entity is a party or by which its Properties are bound, which
default would have a Material Adverse Effect. To the best of Borrower's
knowledge, information and belief, no other party to any contract with any
Borrower Entity under which a default would have a Material Adverse Effect is in
default or breach thereof and no circumstances exist which, with the giving of
notice and/or the passing of time would constitute such default or breach. No
Event of Default or Unmatured Default exists under this Agreement.

      4.12 Casualties; Taking of Properties.  Neither the business nor the
Property of any Borrower Entity is presently impaired as a result of any fire,
explosion, earthquake, flood, drought, windstorm, accident, strike or other
labor disturbance, embargo, requisition or taking of property, cancellation of
contracts, permits, concessions by any domestic or foreign government or any
agency thereof, riot, activities of armed forces or acts of God or of any public
enemy, in any case as would have a Material Adverse Effect.

      4.13 Compliance with Laws.  No Borrower Entity is in violation of any Law
to which it, its business or any of its Properties are subject, the violation of
which would likely have a Material Adverse Effect, and there are no outstanding
citations, notices or orders of noncompliance issued to any Borrower Entity
under any such Law, the violation of which would likely have a Material Adverse
Effect.  Each Borrower Entity has obtained all licenses, permits, franchises, or
other governmental authorizations necessary to the ownership of its Properties
or to the conduct of its business, except for those which, if not obtained,
would not have a Material Adverse Effect.

      4.14 Compliance with Fraud and Abuse Laws. Without limiting any other
provision of this Agreement, no Borrower Entity and no Provider is in violation
of any Fraud and Abuse Law, the violation of which would have a Material Adverse
Effect.

      4.15 ERISA.  No ERISA Event has occurred with respect to any Plan or is
reasonably expected to occur with respect to any Plan, except for those which,
if not obtained, would not have a Material Adverse Effect.

      4.16 Full Disclosure of Material Facts.  Borrower has fully advised Agent
of all matters involving the financial condition, business, operations and
Properties of the Borrower Entities that would be reasonably expected to have a
Material Adverse Effect.  No information, exhibit, or report furnished or to be
furnished by Borrower to Lenders in connection with this Agreement contains, as
of the date thereof, any misrepresentation of fact or failed or will fail to
state any material fact, the omission of which would render the statements
therein materially false or misleading.

      4.17 Accuracy of Projections.  With respect to all business plans and
other forecasts and projections furnished by or on behalf of Borrower and made
available to Agent relating to the financial condition, business, operations or
Properties of the Borrower Entities, all facts stated as such therein were true
and complete in all material respects as of

                                       41
<PAGE>

the time made and all estimates and assumptions were made in good faith and
believed to be reasonable at the time made. As of the Closing Date, nothing had
come to the attention of Borrower that has changed its assessment of any such
matters, except for changes that would not have a Material Adverse Effect.

      4.18 Investment Company Act.  No Borrower Entity is an "investment
company" under the Investment Company Act of 1940, as amended.

      4.19 Personal Holding Company.  No Borrower Entity is a "personal holding
company" as defined in Section 542 of the IRC.

      4.23 Ownership of Patents, Licenses, Etc.  The Borrower Entities own all
licenses, permits, franchises, registrations, patents, copyrights, trademarks,
trade names or service marks, or the rights to use the foregoing, that are
necessary for the continued operation of their business except for such
licenses, etc., which, if not held or owned, would not have a Material Adverse
Effect.

      4.24 Environmental Compliance.  Each Borrower Entity has duly complied
with, and their Properties are owned and operated in compliance with, all
Environmental Laws, the violation of which would have a Material Adverse Effect.
There have been no citations, notices or orders of non-compliance issued to any
Borrower Entity or, to the best of Borrower's knowledge, relating to their
business or Properties pursuant to any Environmental Law, except for those which
would not have a Material Adverse Effect.  Each Borrower Entity has obtained all
required federal, state and local licenses, certificates or permits relating to
them and their Properties as required by applicable Environmental Laws, except
for those which, if not obtained, would not have a Material Adverse Effect.

      4.25 Labor Matters. No Borrower Entity is subject to any collective
bargaining agreements or any decrees or orders requiring them to recognize, deal
with or employ any Person. No demand for collective bargaining has been asserted
against any Borrower Entity by any union or organization. No Borrower Entity has
experienced any strike, labor dispute, slowdown or work stoppage due to labor
dispute and, to the best knowledge of Borrower, there is no such strike,
dispute, slowdown or work stoppage threatened against any Borrower Entity. All
Borrower Entities are in compliance in all

                                       42
<PAGE>

material respects with the Fair Labor Standards Act of 1938,
as amended, except for those matters which would not have a Material Adverse
Effect.

      4.26 OSHA Compliance.  All Borrower Entities are in compliance in all
material respects with the Federal Occupational Safety and Health Act, as

extending credit for the purpose of purchasing or carrying margin stock (within
the meaning of Regulation U issued by the Board of Governors of the Federal
Reserve System).  No proceeds of any Loan will be used to purchase or carry any
margin stock (within the meaning of Regulation U issued by the Board of
Governors of the Federal Reserve System) in violation of applicable law,
including, without limitation, Regulation U issued by the Board of Governors of
the Federal Reserve System.

      4.28 Affiliate Transactions.  No Borrower Entity is a party to any
transaction, contract or agreement with any Affiliate, except for Service
Agreements, lease agreements and other agreements among Borrower and its
Subsidiaries and those other agreements described in Schedule 4.28 hereof.

      4.29 Subordinated Debentures.  The Obligations constitute "Senior
Indebtedness" for the purpose of the subordination provisions of the Indenture
pursuant to which the Subordinated Debentures have been issued.

                           V.  AFFIRMATIVE COVENANTS

     Borrower covenants that, during the term of this Agreement (and thereafter
where expressly stated herein):

      5.1  Payment of Obligations.  Borrower shall pay all amounts owed under
the Obligations when due without setoff, counterclaim or withholdings of any
kind; provided, however, if Borrower is required by law to withhold any taxes
(other than taxes based upon the income of the Lender imposed by the
jurisdiction in which the Lender is organized or from which its interest herein
has been generated) from any payments on the Obligations to any Lender(s),
Borrower shall make additional payments to such Lender(s) along with the regular
payments as they become due so that the end result is that such Lender(s)
receives the amount that the Lender(s) would have received if no such
withholdings were made.


      5.2  Maintenance of Existence and Business.  Except for transactions among
Borrower Entities and other transactions permitted under this Agreement, each
Borrower Entity shall maintain its fundamental existence, name, rights, and
franchises, and shall maintain its qualification and good standing in all states
in which such qualification is necessary (except to the extent that failure to
so qualify would not have a Material Adverse

                                       43
<PAGE>

Effect), and shall continue to operate in the same type of business as such

   accordance with GAAP (excluding year-end adjustments and required footnote
   disclosures), the financial condition of Borrower and its consolidated
   affiliates as of the date of such statements and the results of their
   operations for such period. The quarterly financial information shall further

   president or chief financial officer as to the absence of any Event of
   Default or Unmatured Default,.

       5.3.2 Annual Financial Reports. As soon as available, and in any event
   within one hundred (100) days after the end of each fiscal year, Borrower

   an unqualified audit report prepared by an independent "big six" certified
   public accountant acceptable to Agent showing the financial condition of
   Borrower and its consolidated affiliates at the close of such year and the
   results of its operations during such year. The annual financial information

become applicable, Borrower shall deliver copies of all regular, periodic and

or violation of any contractual duty or duty implied by law.

notice of any material change in the corporate charter or bylaws of Borrower or
any Subsidiary following the encumbrance of the stock thereof in favor of Agent
as required under this Agreement, and shall provide Agent with a copy of such

provided elsewhere in the Loan Documents, and nothing contained in this Section
shall be deemed a waiver of such restrictions).

     5.3.10  Notice of Litigation. Borrower shall give prompt written notice of
any litigation, arbitration, tax audit, administrative proceeding or
investigation that may hereafter be instituted or threatened in writing in which
Borrower would be a party or which otherwise may affect any Borrower Entity or

percent (3%) of Borrower's Consolidated Adjusted EBITDA for the most recent four
(4) fiscal quarters for which Borrower has submitted financial statements to
Agent, as of the time of determination, (ii) actions seeking only monetary
damages in an unspecified amount, if Borrower believes in good faith that the

damages and which are fully covered by insurance, subject only to any applicable
deductible.

                                       45
<PAGE>

          5.3.11 Defaults and Changes. Borrower shall give prompt written notice

     Material Adverse Change.

          5.3.12 Other Information. Borrower shall provide such other
     information respecting the condition or operations, financial or otherwise,
     of the Borrower Entities as Agent or any Lender may from time to time
     reasonably request.

      5.4  Taxes and Other Encumbrances.  Each Borrower Entity shall make due
and timely payment or deposit of all federal, state and local taxes, assessments
or contributions required of it by law, and execute and deliver to Agent, on
demand, appropriate certificates attesting to the payment or deposit thereof;
provided, however, that the Borrower Entities shall not be required to pay or
discharge any such tax, assessment, charge or claim for as long as it is being
diligently contested in good faith by proper proceedings and for which
appropriate reserves are being maintained.

      5.5  Payment of Funded Debt.  Each Borrower Entity shall pay all of its
Funded Debt as and when the same becomes due in accordance with its terms
(unless such payment is not made due to its subordination to the Revolving
Credit Loan), unless the failure to pay would not have a Material Adverse Effect
or is being contested in good faith and appropriate reserves have been made for
payment thereof in accordance with GAAP.

      5.6  Compliance with Laws.  Each Borrower Entity shall observe and comply
with all Laws (including, but not limited to, Fraud and Abuse Laws), and shall
maintain all certificates, franchises, permits, licenses, and authorizations
necessary to the conduct of its business or the operation of its Properties,
except for such Laws, certificates, etc., which, if violated or not obtained and
full penalties were imposed for such violation, would not cause a Material
Adverse Effect.  Each Borrower Entity shall further use its best efforts to
assure the compliance by all Providers with all applicable Laws, including, but
not limited to, medical licensure and Fraud and Abuse Laws, relating to their
providing of professional services, except for those which, if violated and full
penalties were imposed for such violation, would not cause a Material Adverse
Effect.

      5.7  Maintenance of Property.  All Borrower Entities shall maintain their
Property (and any Property leased by or consigned or held under title retention
or conditional sales contracts) in good and workable condition at all times,
subject to ordinary wear and tear, normal discards and replacements due to
functional and useful-life obsolescence, and shall make all repairs,
replacements, additions, and improvements to their Property reasonably necessary
and proper to ensure that the business carried on in connection with their
Property may be conducted properly and efficiently at all times.

                                       46
<PAGE>

      5.8  Compliance with Contractual Obligations.  Each Borrower Entity will
perform all of its obligations in respect of all material contracts to which it
is a party and will use its best efforts to keep, and to take all action to
keep, such contracts in full force and effect and not allow any such contract to
lapse or be terminated or any rights to renew such to be forfeited or canceled,
if such lapse, etc. would have a Material Adverse Effect; provided, however,
that any such contract may lapse or be terminated or such renewal rights may be
forfeited or canceled if in the reasonable business judgment of the Borrower
Entities it is in their best interests to allow or cause such lapse,
termination, forfeiture or cancellation.

      5.9  Further Assurances.  The Borrower Entities shall promptly cure any
defects in the creation, issuance, or delivery of the Loan Documents.  The
Borrower Entities at their expense will execute (or cause to be executed) and
deliver to Agent upon request all such other and further documents, agreements,
and instruments in compliance with or accomplishment of the covenants and
agreements applicable to them in the Loan Documents, or to evidence further and
to describe more fully any Collateral intended as security for the Obligations,
or to correct any omissions in the Loan Documents, or to state more fully the
Obligations and agreements set out in any of the Loan Documents, or to perfect,
protect, or preserve any Encumbrances created pursuant to any of the Loan
Documents, or to make any recordings, to file any notices, or to obtain any
consents, all as may be reasonably necessary or appropriate in connection
therewith.  Borrower appoints Agent as Borrower's attorney-in-fact to execute
any financing statements or other instruments of perfection with respect to the
Collateral.

      5.10 Security Interest; Setoff.  In order to further secure the payment of
the Obligations, Borrower hereby grants to Agent and to each Lender a security
interest and right of setoff against all of Borrower's presently owned or
hereafter acquired monies, items, credits, deposits and instruments (including
certificates of deposit) presently or hereafter in the possession of any Lender
or Agent.  By maintaining any such accounts or other property with a Lender or
Agent, Borrower acknowledges that Borrower voluntarily subjects the property to
the security interest arising hereunder.  Subject to the provisions in Article
IX hereof, a Lender may exercise its rights under this Section without prior
notice (but with prompt notice following the setoff) following an Event of
Default.  Borrower agrees that neither Lenders nor Agent shall be liable for the
dishonor of any instrument after notice of setoff shall have been duly given
resulting from a Lender's exercise of its rights under this Section.

      5.11 Insurance.

            5.11.1 General Insurance Requirements. In addition to the other
      specific requirements set forth in this Agreement and as may be required
      by other Loan Documents, the Borrower Entities shall maintain insurance
      (i) on all insurable Properties now or hereafter owned by them under
      coverage that insures against the risks included in fire and extended
      coverage insurance and against such other risks as are customarily insured
      in their industry, in an

                                       47

     amount equal to not less than the actual cash value thereof and with a
     deductible of no more than One Thousand and No/100 Dollars ($1,000.00),
     (ii) against public liability in the amount of at least One Million and
     No/100 Dollars ($1,000,000.00) per occurrence, and (iii) with respect to
     worker's compensation liabilities in the amount required by law or, if
     higher, the amount customary in the industry. All policies of insurance
     shall be issued by insurance companies acceptable to Agent and shall be in
     form and substance acceptable to Agent.

             5.11.2 Practice-Related Insurance Requirements. The Borrower
     Entities shall maintain insurance for claims, however characterized,
     against them in connection with the provision of medical services by
     Providers and/or ancillary services provided by them at Practices covered
     by Service Agreements, in an amount of at least One Million and No/100
     Dollars ($1,000,000.00) per occurrence with respect to Practices whose
     Providers are physicians and Three Hundred Thousand and No/100 Dollars
     ($300,000.00) per occurrence with respect to Practices whose Providers who
     are not physicians. The Borrower Entities shall further cause each Provider
     to maintain medical malpractice insurance of at least One Million and
     No/100 Dollars ($1,000,000.00) per occurrence. All required insurance shall
     be in form and substance acceptable to Agent.

     5.12 Accounts and Records.  The Borrower Entities shall maintain current
books of record and account, in which full, true, and correct entries will be
made of all transactions.

      5.13 Official Records.  The Borrower Entities shall maintain current
corporate and official records, minute books and stock ledgers.

      5.14 Banking Relationships.  The Borrower Entities shall maintain their
deposit accounts with Lenders or with other FDIC-insured depository
institutions.

      5.15 Right of Inspection.  The Borrower Entities shall permit any officer,
employee, or agent of a Lender or Agent to visit and inspect during ordinary
business hours any of their Property, to examine their books of record and
accounts and corporate records, to take copies and extracts from such books of
record and accounts, and to discuss the affairs, finances, and accounts of the
Borrower Entities with their respective officers, accountants, and auditors, all
at such reasonable times and as often as Agent or a Lender may reasonably desire
and upon reasonable advance notice absent an Event of Default. Without limiting
Agent's right to obtain equitable relief as to any other appropriate right in
this Agreement or in other Loan Documents, Borrower agrees that the rights in
this Section may be enforced by affirmative injunction and, to the extent the
right to review records may be denied, the right may be enforced by a
restraining order prohibiting the interference by Borrower with the exercise of
rights to review of the records pursuant to this Section. Absent an Event of
Default, all expenses of such inspections, etc. shall be paid by the

                                       48
<PAGE>

respective Lenders, and in the presence of an Event of Default, all reasonable
expenses thereof shall be paid by Borrower.

      5.16 ERISA Information and Compliance.  The Borrower Entities shall comply

specified in this Article IX.

      9.2  Powers and Duties of Agent.

           9.2.1 Powers and Duties of Agent; Standard of Care. Agent shall
     perform all duties expressly imposed upon Agent in this Agreement and those
     other duties reasonably incidental thereto, subject to the approval of the
     Required Lenders as provided in this Agreement. Agent's duties hereunder
     are administrative and ministerial in nature, and Agent's capacity is that
     of an independent contractor for Lenders. Agent is not a trustee or other
     fiduciary for Lenders, and Agent has no duties whatsoever to Lenders except
     as expressly set forth in this Agreement. Agent shall have no liability to
     Lenders for any action or inaction relating to this Agreement or the other
     Loan Documents, EVEN FOR MATTERS ARISING FROM ITS ORDINARY NEGLIGENCE,
     except for actual losses caused by its gross negligence or reckless or
     willful misconduct.

          9.2.2 Matters Reserved to all Lenders. Absent the prior approval of
     all Lenders, Agent shall not increase any Lender's Commitment; forgive or
     reduce any principal, interest or fees due a Lender or Agent (unless the
     affected party so agrees); extend scheduled maturities or payment dates;
     release Collateral release the guarantor Subsidiaries, except for the
     release of stock of (and other equity interests in) and guaranties executed
     by Subsidiaries in the course of transactions undertaken by Borrower
     Entities for which the consent of the Required Lenders is not required
     under the other provisions of this Agreement (including, but not limited
     to, transactions for the "unwinding"

                                       61
<PAGE>

of Practice acquisitions to the extent expressly permitted under Sections 6.10
and 6.12 of this Agreement, respecting which Agent may issue releases without
obtaining the approval of any Lenders).

         9.2.3 Limitations on Agent's Duties. Agent shall not be obligated to
take any action hereunder or under any other Loan Document (i) if such action
would, in the opinion of Agent, be contrary to applicable law, this Agreement or
the other Loan Documents, (ii) if it shall not first be specifically indemnified
to its satisfaction pursuant to Section 9.3 hereof against any and all liability
and expense that may be incurred by it by reason of taking or continuing to take
any such action, (iii) if it would likely subject Agent to a tax in any
jurisdiction where it is not then subject to a tax, (iv) if it would likely
require Agent to qualify to do business in any jurisdiction where it is not then
so qualified, unless Agent receives security or indemnity satisfactory to it
against any tax or other liability in connection with such qualification or
resulting from the taking of such action in connection therewith, or (v) if it
would likely subject Agent to in personam jurisdiction in any location where it
is not then so subject.

         9.2.4 Agent's Right to Require Instructions in Performance of Duties.
If Agent, in its sole and absolute discretion, requests instructions from the
Required Lenders with respect to any act or action (including the failure to
act) in connection with this Agreement or any other Loan Document for which the
approval of the Required Lenders or all Lenders is not otherwise required, Agent
shall be entitled, at its option, to refrain from such action, or to continue
such inaction, unless and until Agent shall have received such instructions, and
Agent shall incur no liability by reason of so acting or refraining from action.
No Lender shall have any right of action whatsoever against Agent as a result of
Agent's acting or refraining from acting hereunder or under any other Loan
Document in accordance with the instructions of the Required Lenders in such a
case.

         9.2.5 Agent's Reliance on Others in Performance of Duties. Agent shall
be entitled to rely, and shall be fully protected in relying, upon any note,
writing, resolution, notice, statement, consent, certificate, telex, teletype or
facsimile message, order or other documentary, teletransmission or telephone
message believed by it in good faith to be genuine and correct and to have been
signed, sent or made by the proper Person. Agent may consult with legal counsel
(including counsel for Borrower), accountants and other experts selected by it
with respect to all matters pertaining to this Agreement and the other Loan
Documents and its duties hereunder and thereunder and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel (including counsel for Borrower), accountants or
experts.

                                       62
<PAGE>

         9.2.6 Sharing of Information. Except as otherwise expressly provided in
    this Agreement, Agent shall have no duty or responsibility, either initially
    or on a continuing basis, to provide any Lender with any credit or other
    information concerning the business, prospects, operations, properties,
    financial or other condition or creditworthiness of the Borrower Entities or
    any other Person that may come into its possession, whether before the
    Closing Date or at any time or times thereafter. All notices to be given to
    Borrower by a Lender hereunder shall be concurrently given to Agent.

    9.3  Indemnification of Agent.  To the extent Agent is not reimbursed by
or on behalf of Borrower, and without limiting the obligation of Borrower to do
so, Lenders will Pro Rata reimburse and indemnify Agent, from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses (including attorneys' fees and expenses) or
disbursements of any kind or nature whatsoever that may at any time (including
at any time following the indefeasible repayment in full of the Revolving Credit
Loan) be imposed on, incurred by or asserted against Agent in any way relating
to or arising out of this Agreement or any other Loan Document or the
transactions contemplated thereby or any action taken or omitted by Agent under
or in connection with any of the foregoing, and in particular will reimburse
Agent for out-of-pocket expenses promptly upon demand by Agent therefor, EVEN IF
INCURRED DUE TO THE ORDINARY NEGLIGENCE OF AGENT; provided, however, that no
Lender shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
finally determined by a court of competent jurisdiction and not subject to any
appeal or pursuant to arbitration to have resulted from Agent's gross negligence
or reckless or willful misconduct.  Agent may offset any amounts due Agent by
any Lender against obligations of Agent to that Lender.

    9.4  No Representations by Agent.  Each Lender acknowledges that neither
Agent nor any of its officers, directors, employees, attorneys, accountants or
agents has made any representation or warranty to it regarding the Borrower
Entities, the Revolving Credit Loan, the Collateral or otherwise relating to
this Agreement.  Agent shall not be responsible to any Lender for any recitals,
statements, information, representations or warranties herein or in any other
Loan Document or in any document, instrument, certificate or other writing
delivered in connection herewith or therewith or for the execution,
effectiveness, genuineness, validity, enforceability, perfection, priority or
sufficiency of this Agreement or any other Loan Document or the financial
condition of the Borrower Entities or any other Person, or be required to make
any inquiry concerning either the performance or observance of any of the terms,
provisions or conditions of this Agreement or any other Loan Document, or the
financial condition of the Borrower Entities or any other Person or the
existence or possible existence of any Unmatured Default or Event of Default.

    9.5  Independent Investigations by Lenders.  Each Lender acknowledges
that, independently and without reliance upon Agent or any other Lender and
based on such documents and information as it has deemed and may deem
appropriate, (i) it has made its own appraisal of and investigation into the
business, prospects, operations, properties,

                                       63
<PAGE>

financial and other condition and creditworthiness of the Borrower Entities in
connection with its decision to enter into this Agreement and extend credit to
Borrower hereunder, and (ii) it will continue to make its own credit analysis,
appraisals and decisions in taking or not taking action hereunder.

      9.6  Notice of Default.  Agent shall not be deemed to have knowledge or
notice of the occurrence of any Unmatured Default or Event of Default, other
than any Unmatured Default or Event of Default arising out of the failure to pay
any principal, interest, fees or other amounts payable to Agent for the account
of the Lenders, unless Agent has received written notice from Borrower or a
Lender describing such Unmatured Default or Event of Default and stating that
such notice is a "notice of default." In the event that Agent receives such a
notice, Agent shall promptly give notice thereof to the Lenders; provided,
however, that if any such notice has also been furnished to the Lenders, Agent
shall have no obligation to notify the Lenders with respect thereto.  Each
Lender shall promptly give Agent such a notice upon its actual knowledge of an
Unmatured Default or an Event of Default; provided, however, that the failure of
any Lender to deliver such notice in the absence of gross negligence or reckless
or willful misconduct shall not affect its rights hereunder or under the other
Loan Documents.

      9.7  Funding of Advances Pursuant to Borrowing Notices.  Promptly
following receipt of notice from Agent that a Borrowing Notice has been
submitted, and provided that all conditions to funding are believed to have been
satisfied, each Lender shall, provided that it received timely notice of the new
Loan, transfer to a designated account with Agent that Lender's Pro Rata Share
of the requested funding.  The transfer of funds shall occur within the time
required for funding under this Agreement.  Should any Lender fail to timely
fund its Pro Rata Share of a requested Loan, Agent may, but shall be under no
obligation whatsoever to, advance to Borrower the defaulted Lender's Pro Rata
Share of the requested Loan.  If such an advance is made, it shall be deemed an
advance by Agent for the account of the defaulting Lender and shall bear
interest at the rate applicable to the Loan, payable upon demand.

      9.8  Agent in its Individual Capacity.  With respect to its Commitments,
and the Loans made by it, Agent shall have the same rights and powers under the
Loan Documents as any other Lender or holder of a Note and may exercise the same
as though it were not performing the duties specified herein; and the terms
"Lenders," "Required Lenders," and any similar terms shall, unless the context
clearly otherwise indicates, include Agent in its individual capacity as a
Lender. Agent may accept deposits from, lend money to and generally engage in
any kind of banking, trust, financial advisory or other business with the
Borrower Entities or any of their respective Affiliates as if it were not
performing the servicing duties specified herein, and may accept fees and other
consideration from Borrower for services in connection with this Agreement and
otherwise without having to disclose or account for the same to Lenders.

      9.9  Holders.  Agent may deem and treat the payee of any Note as the
holder thereof and Lender hereunder for all purposes hereof unless and until a
written notice

                                       64
<PAGE>

of the assignment, transfer or endorsement thereof purportedly executed by the
payee, as the case may be, shall have been filed with Agent. Any request,
authority or consent of any Person that, at the time of making such request or
giving such authority or consent, is the holder of any Note according to Agent's
information, shall be conclusive and binding on any subsequent holder,
transferee, assignee or endorsee, as the case may be, of such Note or of any
Note or Notes issued in exchange therefor.

      9.10 Successor Agent.  Agent may resign at any time upon sixty (60) days'
prior written notice to Borrower and the Lenders.  Agent may be removed upon
Agent's insolvency, liquidation or the appointment of a receiver for Agent, by
action of the Required Lenders, at any time upon sixty (60) days' prior written
notice to Borrower and Agent.  Such resignation or removal, as the case may be,
shall take effect upon the appointment of a successor Agent as provided herein.
The Required Lenders will, with Borrower's approval (which shall not be
unreasonably withheld), appoint from among the Lenders a successor Agent.  If no
successor Agent shall have been appointed within such sixty (60) day period, (i)
if no Unmatured Default or Unmatured Default then exists, Borrower may appoint a
successor Agent from among the Lenders, and (ii) otherwise, Agent may appoint,
after consulting with the Lenders and Borrower, a successor agent from among the
Lenders, which Agent, however selected, shall serve as Agent until such time, if
any, as the Required Lenders and Borrower shall have appointed a successor Agent
as provided hereinabove. Upon the written acceptance of any appointment as Agent
hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder and under the other Loan Documents.  After any retiring
Agent's resignation as Agent, the provisions of this Article shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent.

      9.11   Sharing of Payments, etc.  Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, set-off, counterclaim or
otherwise, obtain payment with respect to the Obligations which results in its
receiving more than its Pro Rata Share of the aggregate payments with respect to
all of the Obligations, then (a) such Lender shall be deemed to have
simultaneously purchased from the other Lenders a share in the Obligations so
that the amount of the Obligations held by each of the Lenders shall continue to
equal their respective Pro Rata Shares, and (b) such other adjustments shall be
made from time to time as shall be equitable to insure that the Lenders share
such payments ratably.   If any Lender remits payments to other Lenders under
this Section 9.11 and later is required to refund the same as a preferential
payment or otherwise, the other Lenders who shared in the payment shall
similarly arrange their interests in the Obligations to reverse the distribution
to them as to allow the originally remitting Lender to refund such payment. No
Lender shall exercise its banker's lien, set-off or other right to accomplish
such payment absent Agent's prior confirmation that the exercise of such right
would be consistent with the instructions of the Required Lenders then in effect
regarding the outstanding Event of Default.

      9.12   Separate Liens on Collateral.  Each Lender agrees with the other
Lenders that, with the exception of security interests in deposit accounts and
like property in

                                       65
<PAGE>

the possession of a Lender as expressly provided for in this Agreement, it will
not take or permit to exist any Encumbrance in its favor on any of the
Collateral or other property of any of Borrowers other than Encumbrances
securing the Obligations due to all Lenders pursuant to the Loan Documents.

      9.13   Payments Between Agent and Lenders.  All payments by Agent to any
Lender, and all payments by any Lender to Agent, under the terms of this
Agreement shall be made by wire transfer in immediately available funds to the
receiving party's address specified for notices in this Agreement.  If any of
the Lenders fail to pay when due any sum payable to Agent, then, except as
otherwise provided in Section 9.7 hereof, such sum shall bear interest until
paid at the interest rate per annum for overnight borrowing by the payee from
the Federal Reserve Bank for the period commencing on the date such payment was
due and ending on, but excluding, the date such payment is made.

     9.14   Assignments and Participations.  Any Lender may assign all of its
interest in the Revolving Credit Loan or any portion(s) thereof in the minimum
amount of Ten Million and No/100 Dollars ($10,000,000.00) and in increments of
One Million and No/100 Dollars ($1,000,000.00) each, subject to the prior
written approval of Agent (and of Borrower, provided that no Event of Default
then exists), which approval shall not be unreasonably withheld.  The assignment
shall be evidenced by documents in form and substance acceptable to Agent, and
the acquiring Lender shall expressly assume full responsibility as a Lender
hereunder, including, but not limited to, assumption of the applicable portion
of the Commitment.  Upon consummation of such assignment, the assigning Lender
shall be deemed released from its obligations under the Loan Documents to the
extent of such assignment.  An assignment fee of Three Thousand and No/100
Dollars ($3,000.00) shall be paid to Agent as a condition to any assignment of
an interest in the Revolving Credit Loan (including assignments, if any, among
banks that are already Lenders).  Lenders may sell participation interests in
their interests in the Revolving Credit Loan as long as the terms of such
participations establish that no participant will be regarded as a Lender under
this Agreement and permit the participants to vote in determining the vote of
the Lender which sold the applicable participation only with respect to matters
for which the unanimous vote of all Lenders is required under this Agreement.
Lenders may disclose financial information in their possession to prospective
purchasers of interests in the Revolving Credit Loan and to prospective
participants.

     9.15   Bankruptcy Provisions.  Should any of the Borrower Entities become
a party to a case under the Bankruptcy Code, each Lender shall be entitled to
file its own claim, to the extent such a filing may be necessary.  Agent shall
review each claim before being filed by a Lender to assure that the claim is
filed on a basis consistent with Agent's records and Agent's legal positions
taken pursuant to this Agreement. Should any of the Borrower Entities become a
party to a reorganization proceeding under the Bankruptcy Code, each Lender
shall be recognized as the holder of a separate claim for the purpose of the
approval or rejection of a plan under 11 U.S.C. (S) 1126, may freely vote such
claim, and the provisions of that Section shall control the other provisions of
this Agreement that otherwise require the consent of the Required Lenders or all
Lenders in certain circumstances. Agent

                                       66
<PAGE>

shall continue to administer the Revolving Credit Loan on behalf of Lenders, as
they may be amended by any adopted Plan of Reorganization.

      9.16   Foreclosure of Collateral.  In the event of a foreclosure of any
Collateral, Agent may issue a credit bid for the account of all Lenders, up to
the amount of the then outstanding Obligations.  Any Property acquired at such a
foreclosure (or acquired by Agent through a conveyance in lieu of foreclosure)
shall be held and administered by Agent for the benefit of all Lenders pursuant
to the terms of this Article IX.

      9.17 Procedures for Notices and Approvals.  All notices given among
Lenders and Agent with respect to this Agreement or the other Loan Documents
shall be given in the manner provided in this Agreement.

      9.18   Other Relationships With Borrower.  Each Lender is free to engage
in deposit relationships and other business relationships with the Borrower
Entities, provided that such relationship does not violate any restriction set
forth in this Agreement.

     9.19   Foreign Tax Matters.  Each Lender which is a foreign person (i.e., a
Person other than a United States Person for United States Federal income tax
purposes) hereby agrees that:

     9.19.1  Delivery of Forms. Such Lender shall, no later than the Closing
Date (or, in the case of a Lender which becomes a party hereto after the Closing
Date, the date upon which such Lender becomes a party hereto) deliver to the
Agent and Borrower:

          9.19.1(a) two accurate and complete signed originals of Form 4224, or

          9.19.1(b) two accurate and complete signed originals of Form 1001,

     in each case indicating that such Lender is on the date of delivery thereof
     entitled to receive payments of principal, interest and fees for the
     account of such lending office or offices under this Loan Agreement free
     from withholding of United States Federal income tax.

     9.19.2  Change of Office.  At any time such a Lender changes its lending
office or offices or selects an additional lending office, it shall, at the same
time or reasonably promptly thereafter, deliver to Agent and Borrower in
replacement for, or in addition to, the forms previously delivered by it
hereunder;

                                       67
<PAGE>

          9.19.2(a) if such changed or additional lending office is located in
     the United States, two accurate and complete signed originals of Form 4224,
     or

          9.19.2(b) otherwise, two accurate and complete signed originals of
     Form 1001,

     in each case indicating that such Lender is on the date of delivery thereof
     entitled to receive payments of principal, interest and fees for the
     account of such changed or additional lending office under this Loan
     Agreement free from withholding of United States federal income tax.

     9.19.3  Additional Documentation.  Each such Lender shall, promptly upon
  Agent's or Borrower's reasonable request to that effect, deliver to the Agent
  and Borrower such other forms or similar documentation as may be required from
  time to time by any applicable law, treaty, rule or regulation in order to
  establish such Lender's tax status for withholding purposes.

  9.20   Responses to Requests.  With respect to any consent or approval
requested by Borrower or Agent under a provision of this Agreement, Lenders
shall endeavor to provide to Agent written notice of their approval or
disapproval within seven (7) Business Days of receipt of the request; provided,
however, if any Lender fails to give such notice within seven (7) Business Days,
the request shall be regarded as disapproved by such Lender.

Agreement relating to Obligations shall apply with equal force and effect to
each and all promissory notes executed hereafter which in whole or in part
represent a renewal, extension for any period, increase, or rearrangement of any
part of the Obligations originally represented by any part of such other
Obligations.

      10.3 Application of Payments.  Amounts received with respect to the
Obligations, except for payments or prepayments expressly provided for elsewhere
in this Agreement, shall be applied (i) first, to any expenses due Lenders or
Agent, (ii) second, to any fee due Agent, (iii) third, to accrued and unpaid
interest under any of the Obligations, (iv) fourth, to any commitment fees due
Lenders, and (iii) fifth, to reduce the unpaid principal portion of the
Obligations, in such manner as determined by Agent.

      10.4 Counterparts.  This Agreement may be executed in counterparts with
all signatures or by counterpart signature pages, and it shall not be necessary
that the signatures of all parties be contained on any one counterpart.  Each
counterpart shall be deemed an original, but all of them together shall
constitute one and the same instrument.

      10.5 Negotiated Document.  This Agreement and the other Loan Documents
have been negotiated by the parties with full benefit of counsel and should not
be construed against any party as author.

      10.6 Consent to Jurisdiction; Exclusive Venue.  Each party hereto hereby
irrevocably consents to the jurisdiction of the United States District Court for
the Middle District of Tennessee and of all Tennessee state courts sitting in
Davidson County, Tennessee, for the purpose of any litigation to which Borrower,
Lenders or Agent may be a party and which concerns this Agreement or the
Obligations.  It is further agreed that venue for any such action shall lie
exclusively with courts sitting in Davidson County, Tennessee, unless Lenders
and Agent agree to the contrary in writing.

      10.7 Not Partners; No Third Party Beneficiaries.    The relationship of
Lenders and Borrower is that of lenders and borrower only, and neither is a
fiduciary, partner or joint venturer of the other for any purpose.  This
Agreement has been executed for the sole benefit of Lenders, and no third party
is authorized to rely upon Lenders' rights or duties hereunder.

      10.8 No Reliance on Lenders' Analysis.  Borrower acknowledges and
represents that, in connection with the Obligations, Borrower has not relied
upon any financial projection, budget, assessment or other analysis by Lenders
or Agent upon any representation by Lenders as to the risks, benefits or
prospects of Borrower's business activities or present or future capital needs
incidental thereto, all such considerations having been examined fully and
independently by Borrower.

      10.9 No Marshaling of Assets.  Lenders and Agent may proceed against
collateral securing the Obligations and against parties liable therefor in such
order as they may elect, and neither Borrower nor any surety or guarantor for
Borrower nor any creditor of Borrower shall be entitled to require Lenders or
Agent to marshal assets. The benefit of any rule of law or equity to the
contrary is hereby expressly waived.

      10.10  Impairment of Collateral.  Lenders or Agent (acting as permitted
under this Agreement) may release any Collateral securing the Obligations or
release any party liable therefor.  The defenses of impairment of collateral and
impairment of recourse and any requirement of diligence in collecting the
Obligations are hereby waived.

      10.11  Business Days.  If any payment date under the Obligations falls on
a day that is not a Business Day, or if the last day of any notice period falls
on such a day, the payment shall be due and the notice period shall end on the
next following Business Day.

      10.12  Standard of Care; Limitation of Damages.  Lenders and Agent shall
be liable to Borrower only for matters arising from this Agreement or otherwise
related to the Obligations resulting from such Lender's or Agent's gross
negligence or willful misconduct, AND NOT FOR MATTERS ARISING FROM THEIR
ORDINARY NEGLIGENCE, and liability for all other matters is hereby waived.
Lenders and Agent shall not in any event be liable to Borrower for special or
consequential damages arising from this Agreement or otherwise related to the
Obligations.

      10.13  Incorporation of Schedules.  All Schedules and Exhibits referred to
in this Agreement are incorporated herein by this reference.

      10.14  Indulgence Not Waiver.  Lenders' or Agent's indulgence in the
existence of a default hereunder or any other departure from the terms of this
Agreement shall not prejudice Lenders' or Agent's rights to declare a default or
otherwise demand strict compliance with this Agreement.

      10.15  Cumulative Remedies.  The remedies provided Lenders and Agent in
this Agreement are not exclusive of any other remedies that may be available to
Lenders and Agent under any other document or at law or equity.

      10.16  Amendment and Waiver in Writing.  No provision of this Agreement
can be amended or waived, except by a statement in writing signed by the party
or parties against whom enforcement of the amendment or waiver is sought.
Provisions of this Agreement may be amended or waived by the agreement of
Borrower and the Required Lenders (which consent of the Required Lenders may be
evidenced by the confirmation thereof issued by Agent to Borrower), except that
(i) no amendment or waiver regarding matters expressly requiring the unanimous
consent of Lenders under Section 9.2.2 of this Agreement may be entered into
absent the written consent of all Lenders, (ii) the amendment of Section 9.2.2
hereof, this subsection (ii), the definition of Pro Rata or Pro Rata Share and
the definition of Required Lenders under this Agreement shall require the
written consent of

                                       71
<PAGE>

all Lenders, and (iii) no amendment or waiver may affect the rights or duties of
the Agent or the Issuing Bank without their written consent.

      10.17  Assignment.  This Agreement shall be binding upon and inure to the
benefit of the respective successors and assigns of Borrower and Lenders, except
that Borrower shall not assign any rights or delegate any obligations arising
hereunder without the prior written consent of Lenders. Any attempted assignment
or delegation by Borrower without the required prior consent shall be void.

      10.18  Entire Agreement.  This Agreement and the other written agreements
among Borrower, Lenders and Agent represent the entire agreement between the
parties concerning the subject matter hereof, and all oral discussions and prior
agreements are merged herein.  Provided, if there is a conflict between this
Agreement and any other document executed contemporaneously herewith with
respect to the Obligations, the provision in this Agreement shall control.

      10.19  Severability.  Should any provision of this Agreement be declared
invalid or unenforceable for any reason, the remaining provisions hereof shall
remain in full effect.

      10.20  Time of Essence.  Time is of the essence of this Agreement, and all
dates and time periods specified herein shall be strictly observed.

      10.21  APPLICABLE LAW.  THE VALIDITY, CONSTRUCTION AND ENFORCEMENT OF THIS
AGREEMENT AND ALL OTHER DOCUMENTS EXECUTED WITH RESPECT TO THE OBLIGATIONS SHALL
BE DETERMINED ACCORDING TO THE LAWS OF TENNESSEE APPLICABLE TO CONTRACTS
EXECUTED AND PERFORMED ENTIRELY WITHIN THAT STATE.

      10.22  Captions Not Controlling.  Captions and headings have been included
in this Agreement for the convenience of the parties, and shall not be construed
as affecting the content of the respective Sections.

      10.23  Waiver of Right to Jury Trial.  THE PARTIES HERETO HEREBY KNOWINGLY
AND VOLUNTARILY, WITH BENEFIT OF COUNSEL, WAIVE THE RIGHT TO HAVE ANY DISPUTE
ARISING FROM OR RELATED TO THIS AGREEMENT OR THE OBLIGATIONS TRIED BY A JURY,
WITH THE RESULT THAT ANY SUCH DISPUTE WOULD BE TRIED BY A JUDGE RATHER THAN A
JURY.  BORROWER ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO AGENT
AND LENDERS IN ENTERING INTO THIS AGREEMENT AND CONFIRMS THAT NO REPRESENTATIVE
OF AGENT OR LENDERS HAS MADE ANY STATEMENT OR SUGGESTION THAT THIS PROVISION
WILL NOT BE ENFORCED IN ACCORDANCE WITH ITS TERMS.

      10.24  Facsimile Signatures.  This Agreement may be executed by facsimile
signatures, and shall be effective when Agent has received telecopy
transmissions of the

                                       72
