(including all rights of the Borrower or the beneficiary of such Standby Letter
of Credit to require renewal) later than the earlier of (x) 5 days prior to the
scheduled Termination Date and (y) one year after the date of issuance thereof,

Issuing Bank has notified the Borrower (with a copy to the Administrative Agent)
on or prior to the date for notice of termination set forth in such Letter of
Credit but in any event at least 30 Business Days prior to the date of automatic
renewal of its election not to renew such Standby Letter of Credit (a "Notice of
Termination"); provided that the terms of each Standby Letter of Credit that is

Termination, (II) shall permit such beneficiary, upon receipt of such notice, to
draw under such Standby Letter of Credit prior to the date such Standby Letter
of Credit otherwise would have been automatically renewed and (III) shall not
permit the expiration date (after giving effect to any renewal) of such Standby

the Borrower or a Notice of Termination is given by the Issuing Bank pursuant to
the immediately preceding sentence, such Standby Letter of Credit shall expire
on the date on which it otherwise would have been automatically renewed;
provided, however, that in the absence of receipt of a Notice of Renewal the
Issuing Bank may in its discretion, unless instructed to the contrary by the
Administrative Agent or the Borrower, deem that a Notice of Renewal had been
timely delivered and, in such case, a Notice of Renewal shall be deemed to have
been so delivered for all purposes under this Agreement. The letters of credit
described on Schedule 2.01(b) hereto shall be "Letters of Credit" for all
purposes of the Loan Documents. Within the limits of the Letter of Credit
Facility, and subject to the limits referred to above, the Borrower may request
the issuance of Letters of Credit under this Section 2.01(b), repay any Letter
of Credit Advances resulting from drawings thereunder pursuant to Section
2.03(c) and request the issuance of additional Letters of Credit under this

requested to comprise such Working Capital Borrowing; (iii) the requested

Working Capital Borrowing, make available for the account of its Applicable
Lending Office to the Administrative Agent at the Administrative Agent's
Account, in same day funds, such Lender's Pro Rata Share of such Working Capital

Capital Borrowing, the Administrative Agent shall first make a portion of such
funds equal to the aggregate principal amount of any Letter of Credit Advances
made by the Issuing Bank and by any Lender and outstanding on the date of such
Working Capital Borrowing, plus accrued and unpaid interest thereon to and as of
such date, available to the Issuing Bank and such other Lenders for repayment of
such Letter of Credit Advances.

                  (b) Anything in subsection (a) of this Section 2.02 to
the contrary notwithstanding, (i) the Borrower may not select Eurodollar Rate
Advances for (A) the initial Working Capital Borrowing hereunder or (B) any
Working Capital Borrowing if the aggregate amount of such Working Capital
Borrowing is less than $5,000,000 or if the obligation of the Lenders to make
Eurodollar Rate Advances shall then be suspended pursuant to Section 2.09 or
2.10. In addition, Eurodollar Rate Advances may not be outstanding as part of
more than 10 separate Borrowings.

                  (c) Each Notice of Borrowing shall be irrevocable and
binding on the Borrower. In the case of any Working Capital Borrowing that the
related Notice of Borrowing specifies is to be comprised of Eurodollar Rate
Advances, the Borrower shall indemnify each Lender against any loss, cost or
expense incurred by such Lender as a result of any failure to fulfill on or
before the date specified in such Notice of Borrowing for such Working Capital
Borrowing the applicable conditions set forth in Article III, including, without
limitation, any loss, cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund the
Advance to be made by such Lender as part of such Working Capital Borrowing when
such Advance, as a result of such failure, is not made on such date.

                  (d) Unless the Administrative Agent shall have received
notice from a Lender prior to the date of any Working Capital Borrowing that
such Lender will not make available to

                                       30
<PAGE>   35

the Administrative Agent such Lender's Pro Rata Share of such Working Capital
Borrowing, the Administrative Agent may assume that such Lender has made the
amount of such Pro Rata Share available to the Administrative Agent on the date
of such Working Capital Borrowing in accordance with subsection (a) of this
Section 2.02 and the Administrative Agent may, in reliance upon such assumption,
make available to the Borrower on such date a corresponding amount. If and to
the extent that such Lender shall not have so made the amount of such Pro Rata
Share available to the Administrative Agent, such Lender and the Borrower
severally agree to repay or to pay to the Administrative Agent forthwith on
demand such corresponding amount, together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid or paid to the Administrative Agent, at (i) in the case of the
Borrower, the interest rate applicable at such time under Section 2.07 to
Advances comprising such Working Capital Borrowing and (ii) in the case of such
Lender, the Federal Funds Rate. If such Lender shall pay to the Administrative
Agent such corresponding amount, such amount so paid shall constitute such
Lender's Advance as part of such Working Capital Borrowing for all purposes
under this Agreement.

                  (e) The failure of any Lender to make the Advance to be
made by it as part of any Working Capital Borrowing shall not relieve any other
Lender of its obligation, if any, hereunder to make its Advance on the date of
such Working Capital Borrowing, but no Lender shall be responsible for the
failure of any other Lender to make the Advance to be made by such other Lender
on the date of any Working Capital Borrowing.

                  Section 2.03. Issuance of and Drawings and Reimbursement Under
Letters of Credit. (a) Request for Issuance. Each Letter of Credit shall be
issued upon notice, given not later than 11:00 A.M. (Charlotte, North Carolina
time) on the fifth Business Day prior to the date of the proposed issuance of
such Letter of Credit (or such later day as the Issuing Bank in its sole
discretion shall agree), by the Borrower to the Issuing Bank, which shall give
to the Administrative Agent and each Lender prompt notice thereof by telex or
telecopier. Each notice of issuance of a Letter of Credit (a "Notice of
Issuance") shall be by telephone, confirmed immediately in writing, or by telex
or telecopier, shall be duly executed by a Responsible Officer of the Borrower,
and shall specify therein: (i) the requested date of such issuance (which shall
be a Business Day); (ii) the requested Available Amount of such Letter of
Credit; (iii) the requested expiration date of such Letter of Credit (which
shall comply with the requirements of Section 2.01(b)); (iv) the name and
address of the proposed beneficiary of such Letter of Credit; and (v) the
proposed form of such Letter of Credit, and shall be accompanied by such
application and agreement for letter of credit as the Issuing Bank may specify
to the Borrower for use in connection with such requested Letter of Credit (a
"Letter of Credit Agreement"). If the requested form of such Letter of Credit is
acceptable to the Issuing Bank in its reasonable discretion (taking into account
its customary practices), the Issuing Bank will, upon fulfillment of the
applicable conditions set forth in Article III, make such Letter of Credit
available to the Borrower at its office referred to in Section 8.02 or as
otherwise agreed with the Borrower in connection with such issuance. If and to
the extent that the provisions of any Letter of Credit Agreement shall conflict
with this Agreement, the provisions of this Agreement shall govern.

                  (b) Letter of Credit Reports. The Issuing Bank shall
furnish (i) to the Administrative Agent on the first Business Day of each week a
written report summarizing

                                       31
<PAGE>   36

issuance and expiration dates of Letters of Credit issued during the previous
week and drawings during such week under all Letters of Credit, (ii) to each
Lender on the first Business Day of each month a written report summarizing
issuance and expiration dates of Letters of Credit issued during the immediately
preceding month and drawings during such month under all Letters of Credit and
(iii) to the Administrative Agent and each Lender on the first Business Day of
each calendar quarter a written report setting forth the average daily aggregate
Available Amount during the immediately preceding calendar quarter of all
Letters of Credit.

                  (c) Drawing and Reimbursement. (i) The payment by the
Issuing Bank of a draft drawn under any Letter of Credit shall constitute for
all purposes of this Agreement the making by the Issuing Bank of a Letter of
Credit Advance, which shall be a Base Rate Advance, in the amount of such draft.
Upon demand by the Issuing Bank, with a copy of such demand to the
Administrative Agent, each Lender shall purchase from the Issuing Bank, and the
Issuing Bank shall sell and assign to each such Lender, such Lender's Pro Rata
Share of such outstanding Letter of Credit Advance as of the date of such
purchase, by making available for the account of its Applicable Lending Office
to the Administrative Agent for the account of the Issuing Bank, at the
Administrative Agent's Account, in same day funds, an amount equal to the
portion of the outstanding principal amount of such Letter of Credit Advance to
be purchased by such Lender. Promptly after receipt thereof, the Administrative
Agent shall transfer such funds to the Issuing Bank. The Borrower hereby agrees
to each such sale and assignment. Each Lender agrees to purchase its Pro Rata
Share of an outstanding Letter of Credit Advance on (A) the Business Day on
which demand therefor is made by the Issuing Bank so long as notice of such
demand is given not later than 11:00 A.M. (Charlotte, North Carolina time) on
such Business Day or (B) the first Business Day next succeeding such demand if
notice of such demand is given after such time. Upon any such assignment by the
Issuing Bank to any other Lender of a portion of a Letter of Credit Advance, the
Issuing Bank represents and warrants to such other Lender that the Issuing Bank
is the legal and beneficial owner of such interest being assigned by it, free
and clear of any liens, but makes no other representation or warranty and
assumes no responsibility with respect to such Letter of Credit Advance, the
Loan Documents or any Loan Party. If and to the extent that any Lender shall not
have so made the amount of such Letter of Credit Advance available to the
Administrative Agent, such Lender agrees to pay to the Administrative Agent
forthwith on demand such amount together with interest thereon, for each day
from the date of demand by the Issuing Bank until the date such amount is paid
to the Administrative Agent, at the Federal Funds Rate for its account or the
account of the Issuing Bank, as applicable. If such Lender shall pay to the
Administrative Agent such amount for the account of the Issuing Bank on any
Business Day, such amount so paid in respect of principal shall constitute a
Letter of Credit Advance made by such Lender on such Business Day for purposes
of this Agreement, and the outstanding principal amount of the Letter of Credit
Advance made by the Issuing Bank shall be reduced by such amount on such
Business Day.

<PAGE>   37

                  (ii) The Obligation of each Lender to purchase its Pro
Rata Share of each outstanding Letter of Credit Advance on demand by the Issuing
Bank therefor pursuant to clause (i) of this Section 2.03(c) shall be absolute,
unconditional and irrevocable, and shall be made strictly in accordance with the
terms of clause (i) of this Section 2.03(c) under all circumstances, including,
without limitation, any of the following circumstances:

                  (A) any lack of validity or enforceability of any Loan
         Document, any Letter of Credit Agreement, any Letter of Credit or any
         other agreement or instrument relating thereto (all of the foregoing
         being, collectively, the "L/C Related Documents");

                  (B) the existence of any claim, set-off, defense or other
         right that such Lender may have at any time against any beneficiary or
         any transferee of a Letter of Credit (or any Persons for whom any such
         beneficiary or any such transferee may be acting), the Issuing Bank,
         the Borrower or any other Person, whether in connection with the
         transactions contemplated by the L/C Related Documents or any unrelated
         transaction;

                  (C) the occurrence and continuance of any Default or Event of
         Default; or

                  (D) any other circumstance or happening whatsoever, whether or
         not similar to any of the foregoing.

                  (d) Failure to Make Letter of Credit Advances. The
failure of any Lender to make the Letter of Credit Advance to be made by it on
the date specified in Section 2.03(c) shall not relieve any other Lender of its
obligation hereunder to make its Letter of Credit Advance on such date, but no
Lender shall be responsible for the failure of any other Lender to make the
Letter of Credit Advance to be made by such other Lender on such date.

                  Section 2.04. Repayment of Advances. (a) Working Capital
Advances. The Borrower shall repay to the Administrative Agent for the ratable
account of the Lenders on the Termination Date the aggregate principal amount of
the Working Capital Advances outstanding on such date.

                  (b) Letter of Credit Advances. (i) The Borrower shall
repay to the Administrative Agent for the account of the Issuing Bank and each
Lender that has made a Letter of Credit Advance the principal amount of each
Letter of Credit Advance made by each of them on the earlier of demand and the
Termination Date.

                  (ii) The Obligations of the Borrower under this Agreement,
any Letter of Credit Agreement and any other agreement or instrument relating to
any Letter of Credit shall be unconditional and irrevocable, and shall be paid
strictly in accordance with the terms of this Agreement, such Letter of Credit
Agreement and such other agreement or instrument under all circumstances,
including, without limitation, the following circumstances (it being understood
that any such payment by the Borrower is without prejudice to, and does not
constitute a waiver of,

                                       33
<PAGE>   38

any rights the Borrower might have or might acquire as a result of the payment
by the Issuing Bank of any draft or the reimbursement by the Borrower thereof):

                  (A) any lack of validity or enforceability of any L/C Related
         Document;

                  (B) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Obligations of the Borrower in
         respect of any L/C Related Document or any other amendment or waiver of
         or any consent to departure from all or any of the L/C Related
         Documents;

                  (C) the existence of any claim, set-off, defense or other
         right that the Borrower may have at any time against any beneficiary or
         any transferee of a Letter of Credit (or any Persons for whom any such
         beneficiary or any such transferee may be acting), the Issuing Bank or
         any other Person, whether in connection with the transactions
         contemplated by the L/C Related Documents or any unrelated transaction;

                  (D) any statement or any other document presented under a
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect;

                  (E) payment by the Issuing Bank under a Letter of Credit
         against presentation of a draft or certificate that does not
         substantially comply with the terms of such Letter of Credit;

                  (F) any exchange, release or non-perfection of any Collateral
         or other collateral, or any release or amendment or waiver of or
         consent to departure from the Guaranty or any other guarantee, for all
         or any of the Obligations of the Borrower in respect of the L/C Related
         Documents; or

                  (G) any other circumstance or happening whatsoever, whether or
         not similar to any of the foregoing, including, without limitation, any
         other circumstance that might otherwise constitute a defense available
         to, or a discharge of, the Borrower or a guarantor.

                  Section 2.05. Termination or Reduction of the Commitments. (a)
Optional. The Borrower may, upon at least three Business Days' notice to the
Administrative Agent, terminate in whole or reduce in part the unused portions
of the Letter of Credit Facility and the Unused Working Capital Commitments;
provided, however, that each partial reduction of a Facility shall be in an
aggregate amount of $2,000,000 or an integral multiple of $500,000 in excess
thereof or, if less, the aggregate amount of such Facility.

                  (b) Mandatory. (i) The Working Capital Facility shall be

<PAGE>   39

outstanding thereunder is required to be made pursuant to Section 2.06(b)(i) by
an amount equal to the applicable Reduction Amount.

                  (ii) The Letter of Credit Facility shall be permanently
reduced on the date of each reduction in the Working Capital Facility by an
amount equal to the amount, if any, by which (A) the Letter of Credit Facility
on such date exceeds (B) the Working Capital Facility after giving effect to
such reduction of the Working Capital Facility.

                  (c) Application of Commitment Reductions. Upon each
reduction of a Facility pursuant to this Section 2.05, the Commitment of each
Lender under such Facility shall be reduced by such Lender's Pro Rata Share of
the amount by which such Facility is reduced.

                  SECTION 2.06. Prepayments. (a) Optional. The Borrower may,
upon at least one Business Day's notice in the case of Base Rate Advances and
three Business Days' notice in the case of Eurodollar Rate Advances, in each
case to the Administrative Agent stating the proposed date and aggregate
principal amount of the prepayment, and if such notice is given the Borrower
shall, prepay the aggregate principal amount of the Advances comprising part of
the same Working Capital Borrowing and outstanding on such date, in whole or
ratably in part; provided, however, that (i) each partial prepayment shall be in
an aggregate principal amount of $1,000,000 or an integral multiple of $500,000
in excess thereof and (ii) if any such prepayment of a Eurodollar Rate Advance
is made on a date other than the last day of an Interest Period therefor, the

Advance pursuant to Section 8.04(c).

                   (b) Mandatory. (i) The Borrower shall, on the date of
receipt of the Net Cash Proceeds by the Borrower or any of the Subsidiary

         (iii) The Borrower shall, on each Business Day, pay to the
Administrative Agent for deposit into a cash collateral account in favor of the
Collateral Agent on terms and conditions satisfactory to the Administrative
Agent an amount sufficient to cause the aggregate

                                       35
<PAGE>   40

amount on deposit in such cash collateral account on such Business Day to equal
the amount by which (A) the aggregate Available Amount of all Letters of Credit
outstanding on such Business Day exceeds (B) the Letter of Credit Facility on

Advances comprising part of the same Working Capital Borrowing and outstanding
at such time until all Working Capital Advances are paid in full; and, in the
case of prepayments of the Working Capital Facility required pursuant to clause
(i) of this Section 2.06(b), the amount remaining, if any, after the prepayment
in full of all Advances outstanding at such time (the sum of such prepayment
amounts and remaining amount being, collectively, the "Reduction Amount") may be
retained by the Borrower and the Working Capital Facility shall be automatically
and permanently reduced as set forth in Section 2.05(b)(i).

                  (c) Prepayments to Include Accrued Interest. All

Lender Party from the date of such Advance until such principal amount shall be
paid in full, at the following rates per annum:

                  (i) Base Rate Advances. During such periods as such Advance is
         a Base Rate Advance, a rate per annum equal at all times to the sum of

                  (ii) Eurodollar Rate Advances. During such periods as such
         Advance is a Eurodollar Rate Advance, a rate per annum equal at all
         times during each Interest Period for such Advance to the sum of (A)
         the Eurodollar Rate for such Advance for such Interest Period and (B)
         the Applicable Margin in effect from time to time, payable in arrears

         during such Interest Period every three months from the first day of
         such Interest Period and on the date such Eurodollar Rate Advance shall

                  (b) Default Interest. If all or a portion of (i) the
principal amount of any Advance or (ii) any interest payable thereon or fees or
other amounts payable under this Agreement shall not be paid when due (whether
at the stated maturity, by acceleration or otherwise), such overdue amounts
shall bear interest, payable on demand, at a rate per annum that is (x) in the
case of overdue principal, the rate that would otherwise be applicable thereto
plus 2% per annum or (y) in the case of any overdue interest, fees or other
amounts payable, to the extent permitted by applicable law, the rate determined
pursuant to Section 2.07(a)(i) plus 2% per annum, in each case, from the date of
such non-payment to the date on which such amount is paid in full (after as well
as before judgment).

                  (c) Notice of Interest Rate. Promptly after receipt of a
Notice of Borrowing pursuant to Section 2.02(a), the Administrative Agent shall
give notice to the Borrower and each Lender of the applicable interest rate
determined by the Administrative Agent for purposes of clause (i) or (ii) of
Section 2.07(a), as applicable.

                  SECTION 2.08. Fees. (a) Commitment Fee. The Borrower shall pay

such time shall not be payable by the Borrower so long as such Lender shall be a
Defaulting Lender except to the extent that such commitment fee shall otherwise
have been due and payable by the Borrower prior to such time; and provided
further that no commitment fee shall accrue on any of the Commitments of a
Defaulting Lender so long as such Lender shall be a Defaulting Lender.

                  (b) Letter of Credit Fees. Etc. (i) The Borrower shall

                  (C) if such Conversion is into Eurodollar Rate Advances, the
         requested duration of the Interest Period for such Eurodollar Rate
         Advances.

The Administrative Agent shall give each of the Lenders prompt notice of each
Notice of Conversion received by it, by telex or telecopier. Each Notice of
Conversion shall be irrevocable and binding on the Borrower.

                  (b) Mandatory. (i) On the date on which the aggregate
unpaid principal amount of Eurodollar Rate Advances comprising any Working
Capital Borrowing shall be reduced, by payment or prepayment or otherwise, to
less than $5,000,000, such Advances shall automatically Convert into Base Rate
Advances.

                  (ii) If the Borrower shall fail to select the duration of
any Interest Period for any Eurodollar Rate Advances in accordance with the
provisions contained in the definition of "Interest Period" in Section 1.01, the
Administrative Agent will forthwith so notify the Borrower and the Lenders,
whereupon each such Eurodollar Rate Advance will automatically, on the last day
of the then existing Interest Period therefor, Convert into a Base Rate Advance.

                  (iii) Upon the occurrence and during the continuance of any
Default under Section 6.01(a) or 6.01(f) or any Event of Default, (A) each
Eurodollar Rate Advance will automatically, on the last day of the then existing
Interest Period therefor, Convert into a Base Rate Advance and (B) the
obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate
Advances shall be suspended.

                  SECTION 2.10. Increased Costs, Etc. (a) In the event that, due
to either (i) the introduction of or any change (including any change by way of
imposition or increase of reserve requirements included in the Eurodollar Rate
Reserve Percentage) in or in the interpretation or administration of any
applicable law or regulation after the Closing Date, (ii) the compliance with
any applicable guideline or request from any central bank or other governmental
authority (whether or not having the force of law) or (iii) any other
circumstance affecting the interbank Eurodollar Market or the position of any
Lender Party in such market that leads such Lender Party to reasonably determine
that the Eurodollar Rate for any Interest Period for any Eurodollar Rate Advance
made by such Lender Party will not adequately reflect the cost to such Lender of
making, funding or maintaining such Eurodollar Rate Advance for such Interest
Period, there shall be any increase in the cost to or reduction in the amount
received or receivable by any Lender Party as a result of agreeing to make or of
making, funding or maintaining any Eurodollar Rate Advances, or of agreeing to
issue or of issuing or maintaining Letters of Credit or of agreeing to make or
of making or maintaining Letter of Credit Advances (excluding for purposes of
this Section 2.10 any such increased costs resulting from any taxes (as to which
Section 2.12 shall govern), then the Borrower shall from time to time upon
demand by such Lender Party (with a copy of such demand to the Administrative
Agent), pay to the Administrative Agent for the account of such Lender Party
additional amounts (in the form of an increased rate of, or a different method
of calculating, interest or otherwise as such Lender Party, in its reasonable

                                       39
<PAGE>   44

discretion, shall determine) sufficient to compensate such Lender Party for such
increased cost; provided, however, that a Lender Party claiming additional
amounts under this Section 2.10(a) agrees to use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to designate a
different Applicable Lending Office for any Advances affected by such event if
the making of such a designation would avoid the need for, or reduce the amount
of, such increased cost that may thereafter accrue; provided further that such
designation is made on terms that such Lender Party and its Applicable Lending
Office suffer no economic, legal or regulatory disadvantage, with the object of
avoiding the consequence of the event giving rise to the operation of this
subsection (a). A certificate as to the amount of such increased cost and
showing in reasonable detail the basis for the calculation thereof, submitted to
such Borrower by such Lender Party at the time of demand, shall be conclusive
and binding for all purposes, absent manifest error.

                  (b) If, due to either (i) the introduction of or any
change in or in the interpretation or administration of any applicable law or
regulation after the Closing Date or (ii) the compliance with any applicable
guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
amount of capital required or expected to be maintained by any Lender Party or
any corporation controlling such Lender Party which has or would have the effect
of reducing the rate of return of such Lender Party's capital or assets as a
result of or based upon the existence of such Lender Party's commitments and
obligations under this Agreement to a level below that which such Lender Party
could have achieved but for such change or compliance (taking into consideration
such Lender Party's or any corporation controlling such Lender Party's policies
with respect to capital advances), then, upon demand by such Lender Party (with
a copy of such demand to the Administrative Agent), the Borrower shall pay to
the Administrative Agent for the account of such Lender Party, from time to time
specified by such Lender Party, additional amounts sufficient to compensate such
Lender Party in the light of such circumstances, it being understood and agreed
that a Lender Party shall not be entitled to such compensation as a result of
such Lender Party's compliance with, or pursuant to any request or directive to
comply with, any such law, regulation, guideline or request in effect on the
Closing Date. Any amount payable pursuant to this Section 2.10(b) shall be
payable only to the extent that such Lender Party reasonably determines such
increase in capital to be allocable to the existence of such Lender Party's
commitment to lend or to issue Letters of Credit hereunder or to the issuance or
maintenance of any Letters of Credit. A certificate as to such amounts and
showing in reasonable detail the basis for the calculation thereof submitted to
such Borrower by such Lender Party at the time of demand shall be conclusive and
binding for all purposes, absent manifest error.

                  (c) Notwithstanding any other provision of this Agreement, if
any central bank or other Governmental Authority shall assert that it is
unlawful for any Lender or its Eurodollar Lending Office to perform its
obligations hereunder to make Eurodollar Rate Advances or to continue to fund or
maintain Eurodollar Rate Advances hereunder, with respect to any Eurodollar Rate
Advance affected by circumstances described in this subsection (c), such
Borrower will, and with respect to any Eurodollar Rate Advance affected by
circumstances described in subsections

                                       40
<PAGE>   45

(a) or (b) above, such Borrower may either (i) on the last day of the then
existing Interest Period therefor Convert each Eurodollar Rate Advance affected
by such circumstances into a Base Rate Advance or (ii) if the affected
Eurodollar Rate Advance is then being made pursuant to a Borrowing, cancel such
Borrowing by giving the Administrative Agent telephonic notice (confirmed
promptly in writing) thereof on the same date that such Borrower was notified by
a Lender Party pursuant to subsection (a) or (b) above or this subsection (c)
(as applicable); provided that, if more than one Lender Party is affected at any
time, then all affected Lender Parties must be treated in the same manner
pursuant to this Section 2.10(c). In the event of an illegality as described in
clause (i) of this subsection (c), the obligation of the Appropriate Lenders to
make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended
until the Administrative Agent shall notify the Borrower that such Lender has
determined that the circumstances causing such suspension no longer exist;
provided, however, that, before making any such demand, such Lender Party agrees
to use reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions) to designate a different Applicable Lending Office for
any Advances affected by such event if the making of such a designation would
allow such Lender Party or its Applicable Lending Office to continue to perform
its obligations to make Eurodollar Rate Advances or to continue to fund or
maintain Eurodollar Rate Advances; provided further that such designation is
made on terms that such Lender Party and its Applicable Lending Office suffer no
economic, legal or regulatory disadvantage, with the object of avoiding the
consequence of the event giving rise to the operation of this subsection.

                  (d) Anything in this Agreement to the contrary
notwithstanding, to the extent any notice under Section 2.10 or 2.12 is given by
any Lender Party more than 180 days after such Lender Party has knowledge (or
should have had knowledge) of the occurrence of the event giving rise to the
additional cost, reduction in amounts, loss tax or other additional amounts
described in such Section 2.10 or 2.12, as the case may be, such Lender Party
shall not be entitled to compensation under such Section for any such amounts
incurred or accruing prior to the giving of such notice to the Borrower.

                  SECTION 2.11. Payments and Computations. (a) The Borrower
shall make each payment hereunder and under the Working Capital Notes,
irrespective of any right of counterclaim or set-off (except as otherwise
provided in Section 2.15), not later than 12:00 Noon (Charlotte, North Carolina
time) on the day when due in U.S. dollars to the Administrative Agent at the
Administrative Agent's Account in same day funds. The Administrative Agent will
promptly thereafter cause like funds to be distributed (i) if such payment by
the Borrower is in respect of principal, interest, commitment fees or any other
Obligation then payable hereunder and under the Working Capital Notes to more
than one Lender Party, to such Lender Parties for the account of their
respective Applicable Lending Offices ratably in accordance with the amounts of
such respective Obligations payable to such Lender Parties at such time and (ii)
if such payment by the Borrower is in respect of any Obligation then payable
hereunder to one Lender Party, to such Lender Party for the account of its
Applicable Lending Office, in each case to be applied in accordance with the
terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and
recording of the information contained therein in the Register pursuant to
Section

                                       41
<PAGE>   46

8.07(d), from and after the effective date of such Assignment and Acceptance,
the Administrative Agent shall make all payments hereunder and under the Working
Capital Notes in respect of the interest assigned thereby to the Lender Party
assignee thereunder, and the parties to such Assignment and Acceptance shall
make all appropriate adjustments in such payments for periods prior to such
effective date directly between themselves.

                  (b) The Borrower hereby authorizes each Lender Party, if
and to the extent payment owed to such Lender Party is not made when due
hereunder or, in the case of a Lender, under the Working Capital Note held by
such Lender, to charge from time to time against any or all of the Borrower's
accounts with such Lender Party any amount so due.

                  (c) All computations of interest, fees and commissions
shall be made by the Administrative Agent on the basis of a year of 360 days, in
each case for the actual number of days (including the first day but excluding
the last day) occurring in the period for which such interest, fees or
commissions are payable; provided, however, that (i) interest in respect of
which the rate of interest is calculated on the basis of clause (a) of the
definition of "Base Rate" contained in Section 1.01 and (ii) commitment fees
payable pursuant to Section 2.08(a) shall be calculated on the basis of a year
of 365 (or 366, as the case may be) days for the actual number of days elapsed.
Each determination by the Administrative Agent of an interest rate, fee or
commission hereunder shall be conclusive and binding for all purposes, absent
manifest error.

                  (d) Whenever any payment hereunder or under the Working
Capital Notes shall be stated to be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day, and such extension of
time shall in such case be included in the computation of payment of interest or
commitment fee, as the case may be; provided, however, that, if such extension
would cause payment of interest on or principal of Eurodollar Rate Advances to
be made in the next succeeding calendar month, such payment shall be made on the
immediately preceding Business Day.

                  (e) Unless the Administrative Agent shall have received
notice from the Borrower prior to the date on which any payment is due to any
Lender Party hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each such Lender Party
on such due date an amount equal to the amount due such Lender Party on such
date. If and to the extent the Borrower shall not have so made such payment in
full to the Administrative Agent, each such Lender Party shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Lender
Party, together with interest thereon, for each day from the date such amount is
distributed to such Lender Party until the date such Lender Party repays such
amount to the Administrative Agent, at the Federal Funds Rate.

                  SECTION 2.12. Taxes. (a) Any and all payments by the Borrower
hereunder or under any of the other Loan Documents shall be made, in accordance
with Section 2.11, free and

                                       42
<PAGE>   47

clear of and without deduction for any and ail present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender Party and each Agent, taxes that
are imposed as a result of a present or former connection between the Lender
Party or the Administrative Agent and the jurisdiction of the Governmental
Authority imposing such taxes or any political subdivision or taxing authority
thereof or therein (other than a connection relating to or arising solely from
the Lender Party or the Administrative Agent holding a Working Capital Note or
having executed, delivered or performed its obligations or received or otherwise
collected payment under, or enforced or otherwise exercised its rights under
this Agreement or any of the other Loan Documents) (all such nonexcluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities in respect of
payments hereunder or under the other Loan Documents being, collectively,
"Taxes"). If the Borrower shall be required under applicable Requirements of Law
to deduct any Taxes from or in respect of any sum payable hereunder or under any
Working Capital Note to any Lender Party or any Agent, (i) the sum payable shall
be increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.12) such Lender Party or such Agent, as the case may be, receives an amount
equal to the sum it would have received had no such deductions been made, (ii)
the Borrower shall make such deductions and (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other Governmental
Authority in accordance with applicable Requirements of Law.

                  (b) In addition, the Borrower shall pay any present or
future stamp, recording, documentary, excise, property or similar taxes, charges
or levies that arise from any payment made hereunder or under the Working
Capital Notes or from the execution, delivery or registration of, any
performance under, or otherwise with respect to, this Agreement or the Working
Capital Notes (collectively, "Other Taxes").

                  (c) The Borrower shall indemnify each Lender Party and
each Agent for the full amount of Taxes and Other Taxes, and for the full amount
of taxes of any kind imposed by any jurisdiction on amounts payable under this
Section 2.12, imposed on or paid by such Lender Party or such Agent, as the case
may be, and any liability (including penalties, additions to tax, interest and
expenses) arising therefrom or with respect thereto. The indemnity by the
Borrower provided for in this subsection (c) shall apply and be made whether or
not the Taxes or Other Taxes for which indemnification hereunder is sought have
been correctly or legally asserted; provided, however, that such Lender or such
Agent seeking such indemnification shall take all reasonable actions (consistent
with its internal policy and legal and regulatory restrictions) requested by the
Borrower to assist the Borrower in recovering the amounts paid thereby pursuant
to this subsection (c) from the relevant taxation authority or other
Governmental Authority. Amounts payable by the Borrower under the indemnity set
forth in this subsection (c) shall be paid within 30 days from the date on which
the applicable Lender or Agent, as the case may be, makes written demand
therefor.

                  (d) If the Administrative Agent or any Lender Party
receives a refund in respect of Taxes paid by the Borrower, which in the
reasonable judgment of such Lender Party is

                                       43
<PAGE>   48

allocable to such payment, it shall promptly pay such refund, together with any
other amounts paid by the Borrower in connection with such refunded Taxes, to
the Borrower, net of all out-of-pocket expenses of such Lender Party incurred in
obtaining such refund, provided, that the Borrower agrees to promptly return
such refund to the Administrative Agent or the applicable Lender Party, as the
case may be, if it receives notice from the Administrative Agent or the
applicable Lender Party that such Administrative Agent or Lender Party is
required to repay such refund.

                  (e) Within 30 days after the date of any payment of
Taxes, the Borrower shall furnish to the Administrative Agent, at its address
referred to in Section 8.02, the original or a certified copy of a receipt
evidencing payment thereof, to the extent such a receipt is issued therefor, or
other written proof of payment thereof that is reasonably satisfactory to the
Administrative Agent.

                  (f) Each Lender Party organized under the laws of a
jurisdiction outside the United States shall, on or prior to the date of its
execution and delivery of this Agreement in the case of each Initial Lender or
Initial Issuing Bank, as the case may be, and on the date of the Assignment and
Acceptance pursuant to which it becomes a Lender Party in the case of each other
Lender Party, and from time to time thereafter as reasonably requested in
writing by the Borrower (but only so long thereafter as such Lender Party
remains lawfully able to do so), provide each of the Administrative Agent and
the Borrower with two original Internal Revenue Service forms 1001 or 4224 or
any successor or other form prescribed by the Internal Revenue Service,
certifying that such Lender Party is exempt from or entitled to a reduced rate
of United States withholding tax on payments pursuant to this Agreement or the
other Loan Documents. If the forms provided by a Lender Party at the time such
Lender Party first becomes a party to this Agreement or at the time the Lender
Party changes the jurisdiction of its Applicable Lending Office or designates a
different Applicable Lending Office indicates a United States interest
withholding tax rate in excess of zero, withholding tax at such rate shall be
considered excluded from Taxes unless and until such Lender Party provides the
appropriate form certifying that a lesser rate applies, whereupon withholding
tax at such lesser rate only shall be considered excluded from Taxes for periods
governed by such form; provided, however, that, if at the date of a change in
the jurisdiction of the Applicable Lending Office or designation of a new
Applicable Lending Office of a Lender Party, such Lender Party was entitled to
payments under subsection (a) in respect of withholding tax with respect to
interest paid immediately before the change in the Applicable Lending Office,
then, to such extent, the term Taxes shall include (in addition to withholding
taxes that may be imposed in the future or other amounts otherwise includable in
Taxes) withholding tax, if any, applicable with respect to such new Applicable
Lending Office on such date; provided further that, if at the date of the
Assignment and Acceptance pursuant to which a Lender Party becomes a party to
this Agreement, the Lender Party assignor was entitled to payments under
subsection (a) in respect of withholding tax with respect to interest paid at
such date, then, to such extent, the term Taxes shall include (in addition to
withholding taxes that may be imposed in the future or other amounts otherwise
includable in Taxes) withholding tax, if any, applicable with respect to the
Lender Party assignee on such date.

                                       44
<PAGE>   49

                  (g) For any period with respect to which a Lender Party
has failed to provide the Borrower with the appropriate form, certificate or
other document described in subsection (e) of this Section 2.12 (other than if
such failure is due to a change in the applicable Requirements of Law, or in the
interpretation or application thereof, occurring after the date on which a form,
certificate or other document originally was required to be provided or if such
form, certificate or other document otherwise is not required under subsection
(e) of this Section 2.12), such Lender Party shall not be entitled to
indemnification under subsection (a) or (c) of this Section 2.12 with respect to
Taxes imposed by the United States by reason of such failure; provided, however,
that should a Lender Party become subject to Taxes because of its failure to
deliver a form, certificate or other document required hereunder, the Borrower
shall, at such Lender Party's sole expense, take such steps as such Lender Party
shall reasonably request to assist such Lender Party in recovering such Taxes.

                  (h) Any Lender Party claiming any additional amounts
payable pursuant to this Section 2.12 agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of its Applicable Lending Office or designate a
different Applicable Lending Office if the making of such a change or
designation would avoid the need for, or reduce the amount of, any such
additional amounts that may thereafter accrue, provided that such change or
designation is made on terms that such Lender Party and its Applicable Lending
Office suffer no economic, legal or regulatory disadvantage, with the object of
avoiding the consequence of the event giving rise to the operation of subsection
(a) or (c) above.

                  (i) Each Lender Party represents and agrees that, on the
date hereof and at all times during the term of this Agreement, it is not and
will not be a conduit entity participating in a conduit financing arrangement
(as defined in United States Treasury regulations Section 881-3) with respect to
the Borrowings hereunder (other than a conduit financing arrangement in which
the Borrower, or an Affiliate thereof, is a financing entity) unless the
Borrower has consented to such arrangement prior thereto.

                  SECTION 2.13. Sharing of Payments. Etc. If any Lender Party
shall obtain at any time any payment (whether voluntary, involuntary, through
the exercise of any right of setoff, or otherwise) (a) on account of Obligations
due and payable to such Lender Party under or in respect of this Agreement or
any of the other Loan Documents at such time in excess of its ratable share
(according to the proportion of (i) the amount of such Obligations due and
payable to such Lender Party at such time (other than pursuant to Section 2.10,
2.12, 8.04 or 8.07)

                                       45
<PAGE>   50

to (ii) the aggregate amount of the Obligations due and payable to all Lender
Parties at such time) of payments on account of the Obligations due and payable
to all Lender Parties under or in respect of this Agreement and the other Loan
Documents at such time obtained by all the Lender Parties at such time or (b) on
account of Obligations owing (but not due and payable) to such Lender Party
under or in respect of this Agreement or any of the other Loan Documents at such
time in excess of its ratable share (according to the proportion of(i) the
amount of such Obligations owing to such Lender Party at such time (other than
pursuant to Section 2.10, 2.12, 8.04 or 8.07) to (ii) the aggregate amount of
the Obligations owing (but not due and payable) to all Lender Parties under or
in respect of this Agreement and the other Loan Documents at such time) of
payments on account of the Obligations owing (but not due and payable) to all
Lender Parties under or in respect of this Agreement and the other Loan
Documents at such time obtained by all of the Lender Parties at such time, such
Lender Party shall forthwith purchase from the other Lender Parties such
participations in the Obligations due and payable or owing to them, as the case
may be, as shall be necessary to cause such purchasing Lender Party to share the
excess payment ratably with each of them; provided, however, that if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender Party, such purchase from each other Lender Party shall be rescinded and
such other Lender Party shall repay to the purchasing Lender Party the purchase
price to the extent of such Lender Party's ratable share (according to the
proportion of (A) the purchase price paid to such Lender Party to (B) the
aggregate purchase price paid to all Lender Parties) of such recovery, together
with an amount equal to such Lender Party's ratable share (according to the
proportion of (1) the amount of such other Lender Party's required repayment to
(2) the total amount so recovered from the purchasing Lender Party) of any
interest or other amount paid or payable by the purchasing Lender Party in
respect of the total amount so recovered. The Borrower hereby agrees that any
Lender Party so purchasing a participation from another Lender Party pursuant to
this Section 2.13 may, to the fullest extent permitted under applicable
Requirements of Law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender Party
were the direct creditor of the Borrower in the amount of such participation.

                  SECTION 2.14. Use of Proceeds. The proceeds of the Advances
and issuances of Letters of Credit shall be available (and the Borrower agrees
that it shall use such proceeds and Letters of Credit) to pay to the holders of
Company Stock (other than MCTH) the cash consideration for their shares in the
Merger, to refinance certain Debt of the Borrower and its Subsidiaries
outstanding on the initial Credit Extension Date, to pay fees and expenses
incurred in connection with the consummation of the Transaction and to provide
working capital from time to time to the Borrower and its Subsidiaries;
provided, however, that no more than $33 million of the proceeds of the Advances
shall be used to pay the holders of Company Stock the cash consideration for
their shares in the Merger, to refinance certain Existing Debt and to pay fees
and expenses incurred in connection with the consummation of the Transaction.

                  SECTION 2.15. Defaulting Lenders. (a) In the event that, at
any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such
Defaulting Lender shall owe a Defaulted Advance to the Borrower and (iii) the
Borrower shall be required to make any payment hereunder or under any other Loan
Document to or for the account of such Defaulting

                                       46
<PAGE>   51

Lender, then the Borrower may, so long as no Default shall occur or be
continuing at such time and to the fullest extent permitted by applicable law,
set off and otherwise apply the Obligation of the Borrower to make such payment
to or for the account of such Defaulting Lender against the obligation of such
Defaulting Lender to make such Defaulted Advance. In the event that, on any
date, the Borrower shall so set off and otherwise apply its obligation to make
any such payment against the obligation of such Defaulting Lender to make any
such Defaulted Advance on or prior

                                       47
<PAGE>   52

to such date, the amount so set off and otherwise applied by the Borrower shall
constitute for all purposes of this Agreement and the other Loan Documents an
Advance by such Defaulting Lender made on the date under the Facility pursuant
to which such Defaulted Advance was originally required to have been made
pursuant to Section 2.01. Such Advance shall be a Base Rate Advance and shall be
considered, for all purposes of this Agreement, to comprise part of the
Borrowing in connection with which such Defaulted Advance was originally
required to have been made pursuant to Section 2.01, even if the other Advances
comprising such Borrowing shall be Eurodollar Rate Advances on the date such
Advance is deemed to be made pursuant to this subsection (a). The Borrower shall
notify the Administrative Agent at any time the Borrower exercises its right of
set-off pursuant to this subsection (a) and shall set forth in such notice (A)
the name of the Defaulting Lender and the Defaulted Advance required to be made
by such Defaulting Lender and (B) the amount set off and otherwise applied in
respect of such Defaulted Advance pursuant to this subsection (a). Any portion
of such payment otherwise required to be made by the Borrower to or for the
account of such Defaulting Lender which is paid by the Borrower, after giving
effect to the amount set off and otherwise applied by the Borrower pursuant to
this subsection (a), shall be applied by the Administrative Agent as specified
in subsection (b) or (c) of this Section 2.15.

                  (b) In the event that, at any one time, (i) any Lender
Party shall be a Defaulting Lender, (ii) such Defaulting Lender shall owe a
Defaulted Amount to the Administrative Agent or any of the other Lender Parties
and (iii) the Borrower shall make any payment hereunder or under any other Loan
Document to the Administrative Agent for the account of such Defaulting Lender,
then the Administrative Agent may, on its behalf or on behalf of such other
Lender Parties and to the fullest extent permitted by applicable law, apply at
such time the amount so paid by the Borrower to or for the account of such
Defaulting Lender to the payment of each such Defaulted Amount to the extent
required to pay such Defaulted Amount. In the event that the Administrative
Agent shall so apply any such amount to the payment of any such Defaulted Amount
on any date, the amount so applied by the Administrative Agent shall constitute
for all purposes of this Agreement and the other Loan Documents payment, to such
extent, of such Defaulted Amount on such date. Any such amount so applied by the
Administrative Agent shall be retained by the Administrative Agent or
distributed by the Administrative Agent to such other Lender Parties, ratably in
accordance with the respective portions of such Defaulted Amounts payable at
such time to the Administrative Agent and such other Lender Parties and, if the
amount of such payment made by the Borrower shall at such time be insufficient

Any portion of such amount paid by the Borrower for the account of such
Defaulting Lender remaining, after giving effect to the amount applied by the

shall pay such amount to the Administrative Agent to be held by the
Administrative Agent, to the fullest extent permitted by applicable law, in
escrow or the Administrative Agent shall, to the fullest extent permitted by
applicable law, hold in escrow such amount otherwise held by it. Any funds held
by the Administrative Agent in escrow under this subsection (c) shall be
deposited by the Administrative Agent in an account with NationsBank, in the

made by such Defaulting Lender and to pay any amount payable by such Defaulting
Lender hereunder and under the other Loan Documents to the Administrative Agent
or any other Lender Party, as and when such Advances or amounts are required to

         and payable by such Defaulting Lender to the Administrative Agent
         hereunder;

                  (ii) second, to any other Lender Parties for any amount then
         due and payable by such Defaulting Lender to such other Lender Parties
         hereunder, ratably in accordance with such respective amounts then due
         and payable to such other Lender Parties; and

                  (iii) third, to the Borrower for any Advance then required to
         be made by such Defaulting Lender pursuant to a Commitment of such
         Defaulting Lender.

In the event that any Lender Party that is a Defaulting Lender shall, at any
time, cease to be a Defaulting Lender, any funds held by the Administrative
Agent in escrow at such time with respect to such Lender Party shall be
distributed by the Administrative Agent to such Lender Party and applied by such
Lender Party to the Obligations owing to such Lender Party at such

                                       49

Borrower may have against such Defaulting Lender with respect to any Defaulted
Advance and that the Administrative Agent or any Lender Party may have against
such Defaulting Lender with respect to any Defaulted Amount.

         reasonably expected to have a Material Adverse Effect and (iii) has all
         requisite corporate power and authority (including, without limitation,
         all material governmental licenses, permits and other approvals) to own

         conducted and as proposed to be conducted except to the extent that the
         absence of such requisite corporate power and authority could not be
         reasonably expected to have a Material Adverse Effect. All of the
         outstanding capital stock of the Borrower has been validly issued, is
         fully paid and non-assessable and is owned by the Parent free and clear
         of all Liens, except those created under the Collateral Documents.

         Effect and (iii) has all requisite corporate power and authority
         (including, without limitation, all governmental licenses, permits and
         other approvals) to own or lease and operate its properties and to
         carry on its business as now conducted and as proposed to be conducted
         except to the extent that the absence of such requisite corporate power
         and authority could not be reasonably expected to have a Material
         Adverse Effect.

         Etc. The execution, delivery and performance by each Loan Party of each

         such Loan Party's Constitutive Documents, (ii) violate any applicable
         provision of any material Requirement of Law applicable to such Loan
         Party or any of its material properties, or any material order,
         injunction, writ or decree of any Governmental Authority to which such
         Loan Party or any of its material properties is subject, (iii) conflict
         with or result in the breach of, or constitute a default under, any

                  (d) Governmental and Third Party Approvals. No authorization
         or approval or other action by, and no notice to or filing with, any
         Governmental Authority or any other third party is required for (i) the

         Party of the Liens granted by it pursuant to the Collateral Documents,

         (iv) the exercise by the Administrative Agent or any Lender Party of
         its rights under the Loan Documents or the remedies in respect of the
         Collateral pursuant to the Collateral Documents, except for the
         authorizations, approvals, actions, notices and filings listed on
         Schedule 4.01 (d) hereto, all of which have been duly obtained, taken,

         litigation or proceeding affecting any Loan Party or any of its
         Subsidiaries, including any Environmental Action, pending or, to the
         knowledge of the Borrower, threatened before any court, governmental
         agency or arbitrator that has or could reasonably be expected to have a
         Material Adverse Effect.

         principles applied on a consistent basis, and since September 30, 1997,

         and fair in the light of conditions existing at the time made, it being
         understood by the Lender Parties that such projections as to future
         events are not to be viewed as facts and that actual results during the
         period or periods covered by any such projections may differ from the
         projected results.

                  (j) Other Information. Neither the Information Memorandum nor
         any other information, exhibit or report furnished on or prior to the
         Closing Date by any Loan Party to the Administrative Agent or any
         Lender Party in writing in connection with the negotiation of the Loan
         Documents or pursuant to the terms of the Loan Documents, taken as a
         whole, contained any untrue statement of a material fact or omitted to
         state a material fact necessary to make the statements made herein and
         therein, taken as a whole, not misleading at such time in light of the
         circumstances in which the same were made, it being understood that for
         purposes of this Section 4.01(j), such factual information does not
         include projections and pro forma financial information.

                  (k) Compliance with Margin Retaliations. The Borrower is not
         engaged in the business of extending credit for the purpose of
         purchasing or carrying Margin Stock, and following application of the
         proceeds of each Advance or drawing under each Letter of Credit, not
         more than 25 percent of the value of the assets (either of the Borrower
         only or of the Borrower and its Subsidiaries on a Consolidated basis)
         subject to the provisions of Section 5.02(a) or 5.02(d) or subject to
         any restriction contained in any agreement or instrument between the
         Borrower and any Lender Party or any Affiliate of any Lender Party
         relating to Debt within the scope of Section 6.01 (e) will be Margin
         Stock.

                  (l) Investment Company Act. The Borrower is not an "investment
         company," as such term is defined in the Investment Company Act of
         1940, as amended.

                  (m) ERISA Compliance. Each Plan is in compliance with the
         terms thereof and the applicable provisions of ERISA, the Code and any
         applicable Requirement of Law; no Reportable Event has occurred (or is
         reasonably likely to occur) with respect to any Plan; no Plan is
         insolvent or in reorganization (or is reasonably likely to be insolvent
         or in reorganization), and no written notice of any such insolvency or
         reorganization has been given to the Borrower, any Subsidiary or any
         ERISA Affiliate; no Plan (other than a multiemployer plan) has an
         accumulated or waived funding deficiency (or is reasonably likely to
         have such a deficiency); neither any Loan Party nor any ERISA Affiliate
         has incurred (or is reasonably expected to incur) any liability to or
         on account of a Plan pursuant to Section 409, 502(i), 502(1), 515,
         4062, 4063, 4064, 4201 or 4204 of ERISA or Section 4971 or 4975 of the
         Code or has been notified in writing that it will incur any liability
         under any of the foregoing Sections with respect to any Plan; no
         proceedings have been instituted (or are reasonably likely to be
         instituted) to terminate or to reorganize any Plan or to appoint a
         trustee to administer any Plan, and no written notice of any such
         proceedings has been given to any Loan Party or any ERISA Affiliate;
         and no lien imposed under the Internal Revenue Code or ERISA on the
         assets of any Loan Party or any ERISA Affiliate exists on account of
         any Plan (or is reasonably likely to exist) nor has any Loan Party or
         any ERISA Affiliate been notified in writing that such a lien will be
         imposed on the assets of any Loan Party or any ERISA Affiliate on
         account of any Plan, except to the extent that a breach of any of the
         foregoing representations and warranties in this Section 4.01 (m) would
         not result, individually or in the aggregate, in an amount of

                                       58
<PAGE>   63

         liability that would be reasonably likely to have a Material Adverse
         Effect. No Plan (other than a multiemployer plan) has an Unfunded
         Current Liability that would, individually or when taken together with
         any other liabilities referenced in this Section 4.01 (m), be
         reasonably likely to have a Material Adverse Effect. With respect to
         Plans that are multiemployer plans (as defined in Section 3(37) of
         ERISA), the representations and warranties in this Section 4.01 (m),
         other than any made with respect to (a) liability under Section 4201 or
         4204 of ERISA or (b) liability for termination or reorganization of
         such Plans under ERISA, are made to the best knowledge of the Borrower.

                  (n) Environmental Matters. (i) Other than instances of
         noncompliance that could not reasonably be expected to have a Material
         Adverse Effect, the Borrower and its Subsidiaries are in compliance
         with all Environmental Laws in all jurisdictions in which the Borrower
         and each of its Subsidiaries are currently doing business (including,
         without limitation, having obtained all material Environmental Permits
         required under Environmental Laws.

                  (ii) Neither the Borrower nor any of its Subsidiaries has
         treated, stored, transported or disposed of Hazardous Materials at or
         from any currently or formerly owned real estate or facility relating
         to its business in a manner that could reasonably be expected to have a
         Material Adverse Effect.

                  (o) Title to Properties. The Borrower and each of its
         Subsidiaries has good title to, or leasehold interests in, all property
         necessary for the conduct of their respective businesses free and clear
         of all Liens (other than any Liens permitted by this Agreement), except
         where the failure to have such good title or leasehold interests could
         not, individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect.

                  (p) Taxes. The Borrower, its Subsidiaries and all other
         corporations with whom the Borrower or any Subsidiary join in the
         filing of a consolidated return have filed all Federal income tax
         returns and other material tax returns and reports, domestic and
         foreign, required to be filed, and have paid all material taxes,
         assessments, fees and other governmental charged levied or imposed upon
         them or their properties, income or assets otherwise due and payable,
         except those not yet delinquent or which are being contested in good
         faith. The Borrower, each of its Subsidiaries and each such other
         corporation with whom the Borrower or any Subsidiary joins in the
         filing of a consolidated return have paid, or have provided adequate
         reserves (in the good faith judgment of the management of the Borrower)
         in accordance with GAAP for the payment of all such material taxes,
         assessments, fees and charges relating to all prior taxable years and
         the current taxable year of the Borrower, each of its Subsidiaries and
         each such other corporation with whom the Borrower or any Subsidiary

                                       59
<PAGE>   64

         joins in the filing of a consolidated return. To the best knowledge of
         the Borrower, there is no proposed tax assessment against the Borrower,
         any Subsidiary or any such other corporation with whom the Borrower or
         any Subsidiary joins in the filing of a consolidated return that could
         reasonably be expected to have a Material Adverse Effect.

                            COVENANTS OF THE BORROWER

                  SECTION 5.01. Affirmative Covenants. So long as any Advance or
any other Obligation of any Loan Party under any Loan Document shall remain
unpaid, any Letter of Credit shall be outstanding or any Lender Party shall have
any Commitment hereunder, the Borrower will:

                  (a) Compliance with Laws. Etc. Comply, and cause each of its
         Subsidiaries to comply, in all material respects, with all applicable
         statutes, regulations and other Requirements of Law, such compliance to
         include, without limitation, compliance with ERISA and Environmental
         Laws, except such as may be contested in good faith or as to which a
         bona fide dispute may exist and except to the extent that noncompliance
         therewith could not reasonably be expected to have a Material Adverse
         Effect.

                  (b) Payment of Taxes. Etc. Pay and discharge, and cause each
         of its Subsidiaries to pay and discharge, before the same shall become
         delinquent, (i) all material taxes, assessments and governmental
         charges or levies imposed upon it or upon its property prior to the
         date on which material penalties attach thereto and (ii) all lawful
         material claims that, if unpaid, might by law become a material Lien
         upon its property; provided, however, that neither the Borrower nor any
         of its Subsidiaries shall be required to pay or discharge any such tax,
         assessment, charge or claim that is being contested in good faith and
         by proper proceedings and as to which appropriate reserves (in the good
         faith judgment of the management of the Borrower or such Subsidiary)
         are being maintained in accordance with GAAP, unless and until any Lien
         resulting therefrom attaches to its property and an execution,
         foreclosure or similar proceeding shall have been commenced which, if
         determined adversely to the Borrower or any of its Subsidiaries would,
         either individually or together with all other such Liens, reasonably
         be expected to have a Material Adverse Effect.

                  (c) Maintenance of Insurance. Maintain, and cause each of its
         Subsidiaries to maintain, insurance with insurance companies or
         associations that the Borrower believes are responsible and reputable
         at the time the relevant coverage is placed or renewed, in such amounts
         and covering such risks (and with such risk retentions) as is usually
         carried by companies engaged in similar businesses and owning similar
         properties in the same general areas in which the Borrower or such
         Subsidiary operates.

                                       60
<PAGE>   65

                  (d) Preservation of Corporate Existence. Etc. Preserve and
         maintain, and cause each of its Subsidiaries to preserve and maintain,
         its existence, corporate rights and franchises, except to the extent
         that failure to do so could not reasonably be expected to have a
         Material Adverse Effect; provided, however, that the Borrower and its
         Subsidiaries may consummate the Merger and any other merger or
         consolidation permitted under Section 5.02(c) or any sale or
         disposition permitted under Section 5.02(d); provided further that
         neither the Borrower nor any of its Subsidiaries shall be required to
         preserve any right, permit, license, approval, privilege or franchise
         if the Board of Directors of the Borrower or such Subsidiary shall
         determine that the preservation thereof is no longer desirable in the
         conduct of the business of the Borrower or such Subsidiary, as the case
         may be, and that the loss thereof is not disadvantageous in any
         material respect to the Borrower, such Subsidiary or the Lender
         Parties.

                  (e) Visitation Rights. At any reasonable time and from time to
         time, upon reasonable notice and during normal business hours, permit
         officers and designated representatives of the Administrative Agent or
         the Required Lenders, to examine and make copies of and abstracts from
         the records and books of account of, and visit the properties of, the
         Borrower and any of its Subsidiaries, and to discuss the affairs,
         finances and accounts of the Borrower and any of its Subsidiaries with
         any of their officers or directors and with their independent certified
         public accountants, provided that the Borrower may, if it so chooses,
         be present at or participate in any such discussion.

                  (f) Maintenance of Properties, Etc. Maintain and preserve, and
         cause each of its Subsidiaries to maintain and preserve, all of its
         properties that are used or useful in the conduct of its business in
         good working order and condition, ordinary wear and tear excepted, in
         each case consistent with past practice, and will from time to time
         make or cause to be made all appropriate repairs, renewals and
         replacements thereof, except where the failure to do so would not
         reasonably be likely to have a Material Adverse Effect.

                  (g) Transactions with Affiliates. Conduct, and cause each of
         its Subsidiaries to conduct, all transactions otherwise permitted under
         the Loan Documents with any of their Affiliates (other than any
         Subsidiary or Included Entity) on terms that are fair and reasonable
         and no less favorable to the Borrower or such Subsidiary than it would
         obtain in a comparable arm's-length transaction with a Person not an
         Affiliate, other than (i) reasonable and customary fees paid to members
         of the board of directors of the Borrower and/or its Subsidiaries and
         (ii) the payment of customary annual fees to KKR and/or its Affiliates
         for management, consulting and financial services rendered to the
         Borrower and its Subsidiaries and investment banking fees paid to KKR
         and/or its Affiliates for services rendered in connection with
         divestitures, acquisitions and financings and other transactions.

                  (h) Covenant to Guarantee Obligations and Give Security. Upon
         the formation or acquisition of any new direct or indirect Guarantor
         Subsidiaries by any Loan Party, then the Borrower shall, in each case
         at the Borrower's expense:

                           (i) in connection with the formation or acquisition
                  or a Guarantor Subsidiary, within 20 days after such formation
                  or acquisition, cause each such Guarantor Subsidiary, to duly
                  execute and deliver to the Administrative Agent a Guaranty
                  Supplement under which such Subsidiary guarantees payment of
                  all of the obligations of the Borrower under the Loan

         RELEVANT PERIOD                        AMOUNT

     Closing Date - 9/30/98                   $50,000,000

         amount permitted to be made for such Fiscal Year in accordance with the
         foregoing, 100% of such unused amount (each such amount, a
         "carry-forward amount") may be carried forward to the immediately
         succeeding Fiscal Year and utilized to make Capital Expenditures in
         such succeeding Fiscal Year in the event the amount permitted in
         accordance with the foregoing in such succeeding Fiscal Year has been
         used (it being understood and agreed that no carry-forward amount may
         be carried forward beyond the Fiscal Year immediately succeeding the
         Fiscal Year in which it arose and that no portion of the carry-forward
         amount for any Fiscal Year may be used until the entire amount of
         Capital Expenditures permitted to be made in such Fiscal Year (without
         giving effect to such carry-forward amount) shall be made). The
         Borrower and its Subsidiaries may also make Capital Expenditures in any
         Fiscal Year, in addition to the maximum amount permitted to be made for
         such Fiscal Year in accordance with the foregoing, in an amount equal
         to 50% of the maximum amount (each such amount, a "carry-back amount")
         permitted to be made for the immediately succeeding Fiscal Year in

                                       70
<PAGE>   75

         accordance with the foregoing chart (it being understood and agreed
         that the maximum amount of Capital Expenditures permitted to be made in
         such next succeeding Fiscal Year, in accordance with the foregoing
         chart, shall be reduced by the carry-back amount used in such prior
         Fiscal Year). The Borrower and its Subsidiaries may also make Capital
         Expenditures in respect of the Additional Hospital in an aggregate
         amount not to exceed $60,000,000; provided, however, that, prior to the
         making of any Capital Expenditure by the Borrower and its Subsidiaries
         in respect of the Additional Hospital, the Borrower shall have
         delivered to the Administrative Agent a certificate of a Responsible
         Officer designating a specific hospital as the "Additional Hospital"
         for purposes of this Section 5.02(j) and certifying as to the amount of
         Capital Expenditures made by the Borrower and its Subsidiaries in
         respect of the Additional Hospital.

                  (k) Formation of Subsidiaries. Organize or invest, or permit
         any Subsidiary to organize or invest, in any new Subsidiary other than
         (x) the organization of or investment in a Guarantor Subsidiary and (y)
         the organization of or investment by a Guarantor Subsidiary, or a
         Subsidiary that is a direct or indirect Subsidiary of a Guarantor
         Subsidiary, in another Subsidiary.

         a Responsible Officer of the Borrower setting forth details of such
         Default and the action that the Borrower has taken and proposes to take

the Issuing Bank, direct the Issuing Bank to deliver a Termination Notice to the
beneficiary of each Standby Letter of Credit issued by it, and the Issuing Bank
shall deliver such Termination Notices; provided, however, that in the event of
an actual or deemed entry of an order for relief with respect to any Loan Party
under the Federal Bankruptcy Code, (x) the Commitments of each Lender Party and
the obligation of each Lender Party to make Advances (other than Letter of
Credit Advances by the Issuing Bank or a Lender pursuant to Section 2.03 (c))
and of the Issuing Bank to issue Letters of Credit shall automatically be
terminated and (y) the Working Capital Notes, all such interest and all such
amounts shall automatically become and be due and payable, without presentment,
demand, protest or any notice of any kind, all of which are hereby expressly
waived by the Borrower.

                  SECTION 6.02. Actions in Respect of the Letters of Credit upon
Default. If any Event of Default shall have occurred and be continuing, the
Agent may, or shall at the request of the Required Lenders, irrespective of
whether it is taking any of the actions described in Section 6.01 or otherwise,
make demand upon the Borrower to, and forthwith upon such demand the Borrower
will, pay to the Agent on behalf of the Lender Parties in same day funds at the
Agent's office designated in such demand, for deposit in a cash collateral
account, securing the Obligations of the Borrower in respect of the Letter of
Credit Facility, in favor of the Collateral Agent on terms and conditions
satisfactory to the Administrative Agent, an amount equal to the aggregate
Available Amount of all Letters of Credit then out standing. If at any time the
Agent determines that any funds held in such cash collateral account are subject
to any right or claim of any Person other than the Agent and the Lender Parties
or that the total amount of such funds is less than the aggregate Available
Amount of all Letters of Credit, the Borrower will, forthwith upon demand by the
Agent, pay to the Agent, as additional funds to be deposited and held in such
cash collateral account, an amount equal to the excess of (a) such aggregate
Available Amount over (b) the total amount of funds, if any, then held in such
cash collateral account that the Administrative Agent determines to be free and
clear of any such right and claim. Upon the drawing of any Letter of Credit for
which funds are on deposit in such cash collateral account, such funds shall be
applied to reimburse the Issuing Bank or Lenders, as applicable, to the extent
permitted by applicable law.

                                   ARTICLE VII

                                   THE AGENTS

                  SECTION 7.01. Authorization and Action. (a) Each Lender Party
(in its capacities as a Lender, the Issuing Bank (if applicable) and a potential
Hedge Bank) hereby appoints and authorizes the Administrative Agent to take such
action as agent on its behalf and to exercise such powers and discretion under
this Agreement and the other Loan Documents as are delegated to the
Administrative Agent by the terms hereof and thereof, together with such powers
and discretion as are reasonably incidental thereto. As to any matters not
expressly provided for by the Loan Documents (including, without limitation,
enforcement or collection of the Working Capital Notes), the Administrative
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully protected
in so acting or refraining from acting) upon the instructions of the Required
Lenders, and such instructions shall be binding upon all Lender Parties and all
holders of Working Capital Notes; provided, however, that the Administrative
Agent shall not be required to take any action (i) that exposes the
Administrative Agent to personal liability or that is contrary to this Agreement
or applicable Requirements of Law or (ii) as to which the Administrative Agent
has not received adequate security or indemnity (whether pursuant to Section
7.05 or otherwise). If the security or indemnity furnished to the Administrative
Agent for any purpose under or in respect of the Loan Documents shall, in the
good faith opinion of the Administrative Agent, be insufficient or become
impaired, then the Administrative Agent may require additional security or
indemnity and cease, or not commence, to follow the directions or take the
actions indemnified against until such additional security or indemnity is
furnished. The Administrative Agent hereby agrees to give to each Lender Party
prompt notice of each notice given to it by the Borrower pursuant to the terms
of this Agreement.

                  (b) The Administrative Agent shall also act as the
"collateral agent" under the Loan Documents, and each of the Lender Parties (in
its capacities as a Lender, the Issuing Bank (if applicable) and a potential
Hedge Bank) hereby appoints and authorizes the Administrative Agent to act as
the agent of such Lender for purposes of acquiring, holding and enforcing any
and all Liens on Collateral granted by any of the Loan Parties to secure any of
the Secured Obligations, together with such powers and discretion as are
reasonably incidental thereto. The Administrative Agent may from time to time in
its discretion appoint any of the other Lender Parties or any of the Affiliates
of a Lender Party to act as its co-agent or sub-agent for purposes of holding or
enforcing any Lien on the Collateral (or any portion thereof) granted under the
Collateral Documents or of exercising any rights and remedies thereunder at the
direction of the Administrative Agent. In this connection, the Administrative
Agent, as "collateral agent", and such co-agents and sub-agents shall be
entitled to the benefits of all provisions of this Article VII (including,
without limitation, Section 7.05, as though such co-agents or sub-agents were
the "collateral agent" under the Loan Documents) as if set forth in full herein
with respect thereto.

                                       81
<PAGE>   86

                  (c) The Syndication Agent shall not have any powers or
discretion under this Agreement or any of the other Loan Documents other than
those bestowed upon it as a co-agent or sub-agent from time to time by the
Administrative Agent pursuant to subsection (b) of this Section 7.01, and each
of the Lender Parties hereby acknowledges that the Syndication Agent shall not
have any liability under this Agreement or any of the other Loan Documents.

                  SECTION 7.02. Administrative Agent's Reliance. Etc. Neither
the Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with the Loan Documents, except for its or their own gross
negligence or willful misconduct as determined in a final, nonappealable
judgment by a court of competent jurisdiction. Without limitation of the
generality of the immediately preceding sentence, the Administrative Agent: (a)
may treat the payee of any Working Capital Note as the holder thereof until the
Administrative Agent receives and accepts an Assignment and Acceptance entered
into by the Lender that is the payee of such Working Capital Note, as assignor,
and an Eligible Assignee, as assignee, as provided in Section 8.07; (b) may
consult with legal counsel (including counsel for any Loan Party), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken in good faith by it in accordance with
the advice of such counsel, accountants or experts; (c) makes no warranty or
representation to any Lender Party and shall not be responsible to any Lender
Party for any statements, warranties or representations (whether written or
oral) made in or in connection with the Loan Documents; (d) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants or conditions of any Loan Document on the part of any Loan
Party or to inspect the property or assets (including the books and records) of
any Loan Party; (e) shall not be responsible to any Lender Party for the due
execution, legality, validity, enforceability, genuineness, sufficiency or value
of, or the perfection or priority of any lien or security interest created or
purported to be created under or in connection with, any Loan Document or any
other instrument or document furnished pursuant thereto; and (f) shall incur no
liability under or in respect of any Loan Document by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telegram,
telecopy or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

                  SECTION 7.03. NationsBank, NMS and Affiliates. With respect to
its Commitments, the Advances made by it and the Working Capital Note or Working
Capital Notes issued to it, NationsBank shall have the same rights and powers
under the Loan Documents as any other Lender and may exercise the same as though
it were not the Administrative Agent; and the term "Lender Party" or "Lender
Parties" shall, unless otherwise expressly indicated, include NationsBank in its
individual capacity. NationsBank, NMS and their respective affiliates may accept
deposits from, lend money to, act as trustee under indentures of, accept
investment banking engagements from and generally engage in any kind of business
with, any Loan Party, any of its Subsidiaries and any Person who may do business
with or own securities of any Loan Party or any such Subsidiary, all as if
NationsBank and NMS were not the Agents and without any duty to account therefor
to the Lender Parties.

<PAGE>   87

                  SECTION 7.04. Lender Party Credit Decision. Each Lender Party
acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender Party and based on the financial
statements referred to in Section 4.01 and such other documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Lender Party also acknowledges that it will,
independently and without reliance upon the Administrative Agent or any other
Lender Party and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

                  SECTION 7.05. Indemnification. (a) Each Lender Party severally
agrees to indemnify the Administrative Agent (to the extent not promptly
reimbursed by the Borrower) from and against such Lender Party's ratable share
(determined as provided below) of any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever that may be imposed on, incurred by, or
asserted against the Administrative Agent in any way relating to or arising out
of the Loan Documents or any action taken or omitted by the Administrative Agent
under the Loan Documents; provided, however, that no Lender Party shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Administrative Agent's gross negligence or willful misconduct as
determined in a final, nonappealable judgment by a court of competent
jurisdiction. In the case of any claim, investigation, litigation or proceeding
for which indemnity under this Section 7.05(a) applies, such indemnity shall
apply whether or not such claim, investigation, litigation or proceeding is
brought by the Administrative Agent, any of the other Agents, any of the Lender
Parties or a third party. Without limitation of the foregoing, each Lender
severally agrees to reimburse the Administrative Agent promptly upon demand for
its ratable share of any costs and expenses (including, without limitation, fees
and expenses of counsel) payable by the Borrower under Section 8.04, to the
extent that the Administrative Agent is not promptly reimbursed for such costs
and expenses by the Borrower. For purposes of this Section 7.05(a), the Lender
Parties' respective ratable shares of any amount shall be determined, at any
time, according to the sum of (i) the aggregate principal amount of the Advances
outstanding at such time and owing to the respective Lender Parties, (ii) their
respective Pro Rata Shares of the aggregate Available Amount of all Letters of
Credit outstanding at such time and (iii) their respective Unused Working
Capital Commitments at such time; provided that the aggregate principal amount
of Letter of Credit Advances owing to the Issuing Bank shall be considered to be
owed to the Lenders ratably in accordance with their respective Working Capital
Commitments. If any Defaulted Advance shall be owing by any Defaulting Lender at
any time, such Lender's Commitment with respect to the Facility under which such
Defaulted Advance was required to have been made shall be considered to be
unused for purposes of this Section 7.05(a) to the extent of the amount of such
Defaulted Advance. The failure of any Lender Party

                                       83
<PAGE>   88

to reimburse the Administrative Agent promptly upon demand for its ratable share
of any amount required to be paid by the Lender Party to the Administrative
Agent as provided herein shall not relieve any other Lender Party of its
obligation hereunder to reimburse the Administrative Agent for its ratable share
of such amount, but no Lender Party shall be responsible for the failure of any
other Lender Party to reimburse the Administrative Agent for such other Lender
Party's ratable share of such amount. Without prejudice to the survival of any
other agreement of any Lender Party hereunder, the agreement and obligations of
each Lender Party contained in this Section 7.05(a) shall survive the payment in
full of principal, interest and all other amounts payable hereunder and under
the other Loan Documents.

                  (b) Each Lender severally agrees to indemnify the Issuing
Bank (to the extent not promptly reimbursed by the Borrower) from and against
such Lender's Pro Rata Share of any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever that may be imposed on, incurred by, or
asserted against the Issuing Bank in any way relating to or arising out of the
Loan Documents or any action taken or omitted by the Issuing Bank under the Loan
Documents; 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 resulting from the Issuing Bank's gross
negligence or willful misconduct as determined in a final, nonappealable
judgment by a court of competent jurisdiction. In the case of any claim,
investigation, litigation or proceeding for which indemnity under this Section
7.05(b) applies, such indemnity shall apply whether or not such claim,
investigation, litigation or proceeding is brought by the Issuing Bank, any of
the other Lender Parties or a third party. Without limitation of the foregoing,
each Lender severally agrees to reimburse the Issuing Bank promptly upon demand
for its Pro Rata Share of any costs and expenses (including, without limitation,
fees and expenses of counsel) payable by the Borrower under Section 8.04, to the
extent that the Issuing Bank is not promptly reimbursed for such costs and
expenses by the Borrower. The failure of any Lender to reimburse the Issuing
Bank promptly upon demand for its Pro Rata Share of any amount required to be
paid by the Lenders to the Issuing Bank as provided herein shall not relieve any
other Lender of its obligation hereunder to reimburse the Issuing Bank for its
Pro Rata Share of such amount, but no Lender shall be responsible for the
failure of any other Lender to reimburse the Issuing Bank for such other
Lender's Pro Rata Share of such amount. Without prejudice to the survival of any
other agreement of any Lender hereunder, the agreement and obligations of each
Lender contained in this Section 7.05(b) shall survive the payment in full of
principal, interest and all other amounts payable hereunder and under the other
Loan Documents.

                  SECTION 7.06. Successor Administrative Agent. The
Administrative Agent may resign at any time by giving written notice thereof to
the Lender Parties and the Borrower and may be removed at any time with or
without cause by the Required Lenders. Upon any such resignation or removal, the
Required Lenders shall have the right to appoint a successor Agent. If no
successor Administrative Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after the
retiring Administrative Agent's giving of notice of resignation or the Required
Lenders' removal of the retiring Administrative Agent, then the retiring
Administrative Agent may, on behalf of the Lender Parties, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the laws
of the United States or of any state thereof and having a combined capital and
surplus of at least

                                       84
<PAGE>   89

$250,000,000. If within 45 days after written notice is given of the retiring
Administrative Agent's resignation or removal under this Section 7.06 no
successor Administrative Agent shall have been appointed and shall have accepted
such appointment, then on such 45th day (a) the retiring Administrative Agent's
resignation or removal shall become effective, (b) the retiring Administrative
Agent shall thereupon be discharged from its duties and obligations under the
Loan Documents and (c) the Required Lenders shall thereafter perform all duties
and obligations of the retiring Administrative Agent under the Loan Documents
until such time, if any, as the Required Lenders appoint a successor
Administrative Agent as provided above in this Section 7.06. Upon the acceptance
of any appointment as Administrative Agent hereunder by a successor
Administrative Agent and upon the execution and filing or recording of such
financing statements, or amendments thereto, and such amendments or supplements
to the Mortgages, and such other instruments or notices, as may be necessary or
desirable, or as the Required Lenders may request, in order to continue the
perfection of the Liens granted or purported to be granted by the Collateral
Documents, such successor Administrative Agent shall succeed to and become
vested with all the rights, powers, discretion, privileges and duties of the
retiring Administrative Agent, and the ret Administrative Agent shall be
discharged from its duties and obligations under the Loan Documents. After any
retiring Administrative Agent's resignation or removal hereunder as
Administrative Agent, the provisions of this Article VII shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

                                  ARTICLE VIII

                                  MISCELLANEOUS

                  SECTION 8.01. Amendments, Etc. No amendment or waiver of any
provision of this Agreement or the Working Capital Notes or any other Loan
Document, nor consent to any departure by the Borrower therefrom, shall in any
event be effective unless the same shall be in writing and signed (or, in the
case of the Collateral Documents, consented to) by the Required Lenders, and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given; provided, however, that no amendment,
waiver or consent shall, unless in writing and signed by each Lender directly
adversely affected thereby (other than any Lender that is, at such time, a
Defaulting Lender), do any of the following at any time: (i) waive any of the
conditions specified in Section 3.01 or, in the case of the initial Borrowing or
the initial issuance of a Letter of Credit, Section 3.02, (ii) change the number
of Lenders or the percentage of (x) the Commitments, (y) the aggregate unpaid
principal amount of the Advances or (z) the aggregate Available Amount of
outstanding Letters of Credit that, in each case, shall be required for the
Lenders or any of them to take any action hereunder, (iii) amend this Section
8.01, (iv) increase the Commitment of such Lender or subject such Lender to any
additional Obligations, (v) reduce the principal of, or interest on, the Working
Capital Notes or any fees payable hereunder or (vi) postpone any date fixed for
any scheduled payment of principal, or interest on, the Working Capital Notes or
any fees payable hereunder; provided further that no amendment, waiver or
consent shall, unless in writing and signed by the Supermajority Lenders, (x)
release all or substantially all of the Collateral in any transaction or series
of related transactions (other than any transaction permitted by this Agreement)
or (y)

                                       85

reduce or limit the Obligations of any Guarantor under Section 1 of the Guaranty
or otherwise limit such Guarantor's liability with respect to the Obligations
owing to the Agents and the Lender Parties (other than by virtue of a release of
such Guarantor as permitted by the Guaranty); provided further that no
amendment, waiver or consent shall, unless in writing and signed by the Issuing
Bank, in addition to the Lenders required above to take such action, affect the
rights or obligations of the Issuing Bank under this Agreement.

                  SECTION 8.02. Notices, Etc. All notices and other
communications provided for hereunder shall be in writing (including
telegraphic, telecopy or telex communication) and mailed, telegraphed,

                  SECTION 8.03. No Waiver; Remedies. No failure on the part of
any Lender Party or the Administrative Agent to exercise, and no delay in
exercising, any right hereunder or under any Working Capital Note shall operate
as a waiver thereof; nor shall any single or partial exercise of any such right
preclude any other or further exercise thereof or the exercise of any other
right. The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

                  SECTION 8.04. Costs, Expenses. (a) The Borrower agrees to pay

                  exchange for any or all of the Pledged Debt;

                           (iii)    all additional shares of stock of any issuer
                  of the Pledged Shares from time to time acquired by such
                  Pledgor in any manner, and the certificates representing such
                  additional shares, and all dividends, cash, instruments and
                  other property from time to time received, receivable or
                  otherwise distributed in respect of or in exchange for any or
                  all of such shares; and

                           (iv)     all additional indebtedness from time to
                  time owed to such Pledgor by any Subsidiary of the Borrower or
                  any Included Entity and the instruments evidencing such
                  indebtedness, and all interest, cash, instruments and other
                  property from time to time received, receivable or otherwise
                  distributed in respect of or in exchange for any or all of
                  such indebtedness; and

                  (b)      all proceeds of any and all of the foregoing
         Collateral (including, without limitation, proceeds that constitute
         property of the types described in clause (a) of this Section 1).

SECTION 2. SECURITY FOR OBLIGATIONS.

                  (a)      This Agreement secures the payment of all Obligations
         of the Borrower and each Guarantor now or hereafter existing under the
         Loan Documents and the Bank Hedge Agreements, whether for principal,
         interest, fees, expenses or otherwise (all such Obligations being the
         "Loan Party Secured Obligations"). Without limiting the generality

                                       2
<PAGE>   119

         of the foregoing, this Agreement secures the payment of all amounts
         that constitute part of the Secured Obligations and would be owed by
         the Borrower or any Guarantor to any of the Secured Parties under the
         Loan Documents or the Bank Hedge Agreements but for the fact that they
         are unenforceable or not allowable due to the existence of a
         bankruptcy, reorganization or similar proceeding involving the Borrower
         or any Guarantor.

                  (b)      The Parent's liability under this Pledge Agreement
         shall be limited to the Collateral pledged by it hereunder, it being
         agreed that the pledge set forth herein is a nonrecourse obligation of
         the Parent and that the Administrative Agent's right to recover against
         the Parent hereunder shall be limited solely to the Collateral pledged
         by it hereunder. Without limiting the generality of the foregoing, the
         non-recourse pledge hereunder secures the payment of all amounts that
         constitute part of the Secured Obligations and would be owed by the
         Borrower to the Administrative Agent or any Secured Party under the
         Loan Documents or a Bank Hedge Agreement but for the fact that they are
         unenforceable or not allowable due to the existence of a bankruptcy,
         reorganization or similar proceeding involving the Borrower.

SECTION 3. PLEDGORS REMAIN LIABLE. Anything herein to the contrary
notwithstanding, (a) the exercise by the Administrative Agent of any of the
rights hereunder shall not release any Pledgor from any of its duties or
obligations under the Collateral and (b) neither the Administrative Agent nor
any Secured Party shall have any obligation or liability under the Collateral by
reason of this Agreement, nor shall the Administrative Agent or any Secured
Party be obligated to perform any of the obligations or duties of any Pledgor
thereunder or to take any action to collect or enforce any claim for payment
assigned hereunder.

SECTION 4. DELIVERY AND CONTROL OF SECURITY COLLATERAL. (a) All certificates or
instruments representing or evidencing Security Collateral shall be delivered to
and held by or on behalf of the Administrative Agent pursuant hereto and shall
be in suitable form for transfer by delivery, or shall be accompanied by duly
executed and undated instruments of transfer or assignment in blank, all in form
and substance satisfactory to the Administrative Agent. The Administrative Agent
shall have the right, at any time in its discretion during the continuance of an
Event of Default and without notice to the applicable Pledgor, to transfer to or
to register in the name of the Administrative Agent or any of its nominees any
or all of the Security Collateral owned by such Pledgor, subject only to the
revocable rights specified in Section 8(a). In addition, the Administrative
Agent shall have the right at any time during the continuance of an Event of
Default to exchange certificates or instruments representing or evidencing
Security Collateral for certificates or instruments of smaller or larger
denominations.

                  (b)      With respect to any Security Collateral that
constitutes a security and is not represented or evidenced by a certificate or
an instrument, the Pledgor of such Security Collateral shall cause the issuer
thereof either (i) to register the Administrative Agent as the registered owner
of such security or (ii) to agree in writing with the Pledgor of such Security
Collateral and

                                       3
<PAGE>   120

the Administrative Agent that such issuer will comply with instructions with
respect to such security originated by the Administrative Agent without further
consent of such Pledgor, such agreement to be in form and substance satisfactory
to the Administrative Agent.

SECTION 5. REPRESENTATIONS AND WARRANTIES. Each Pledgor represents and warrants
as follows:

                  (a)      The chief place of business and chief executive
         office of the Borrower are specified on the signature pages for such
         Pledgor or on the Pledge Agreement Supplement. Such Pledgor is the
         legal and beneficial owner of the Collateral pledged by such Grantor
         hereunder free and clear of any Lien, except for the security interest
         created by this Agreement. No effective financing statement or other
         instrument similar in effect covering all or any part of the Collateral
         is on file in any recording office, except such as may have been filed
         in favor of the Administrative Agent relating to this Agreement. Such
         Pledgor has no trade names.

                  (b)      The Pledged Shares have been duly authorized and
         validly issued and are fully paid and non-assessable. The Pledged Debt
         has been duly authorized, authenticated or issued and delivered, is the
         legal, valid and binding obligation of the issuers thereof.

                  (c)      As of the Closing Date, the Pledged Shares constitute
         the percentage of the issued and outstanding shares of stock of the
         issuers thereof indicated on Schedule I. As of the Closing Date, the
         Pledged Debt is outstanding in the principal amount indicated on
         Schedule I.

                  (d)      This Agreement and the pledge of the Security
         Collateral pursuant hereto create a valid and perfected first priority
         security interest in the Collateral, securing the payment of the
         Secured Obligations, and all filings and other actions necessary or
         desirable to perfect and protect such security interest have been duly
         taken (it being understood that with respect to proceeds of Collateral
         and Collateral constituting dividends, distributions and payments that
         the applicable Pledgor is entitled to retain pursuant to Section 8,
         this representation is limited to the extent that the security
         interests therein are perfected under Section 9-306 of the UCC after
         actions in respect thereof that are required hereunder are taken).

                  (e)      No consent of any other Person and no authorization,
         approval or other action by, and no notice to or filing with, any
         governmental authority or regulatory body or other third party is
         required either (i) for the grant by such Pledgor of the assignment and
         security interest granted hereby, for the pledge by such Pledgor of the
         Security Collateral pursuant hereto or for the execution, delivery or
         performance of this Agreement by such Pledgor, (ii) for the perfection
         or maintenance of the pledge, assignment and security interest created
         hereby (including the first priority nature of such pledge,

                                       4
<PAGE>   121

         assignment or security interest), except for the filing of financing
         and continuation statements under the Uniform Commercial Code, which
         financing statements have been duly filed, or (iii) for the exercise by
         the Administrative Agent of its voting or other rights provided for in
         this Agreement or the remedies in respect of the Collateral pursuant to
         this Agreement, except as may be required in connection with the
         disposition of any portion of the Security Collateral by laws affecting
         the offering and sale of securities generally.

SECTION 6. FURTHER ASSURANCES. (a) Each Pledgor agrees that from time to time,
at its own expense, such Pledgor will promptly execute and deliver all further
instruments and documents, and take all further action, that may be necessary or
desirable, or that the Administrative Agent may reasonably request, in order to
perfect and protect any pledge, assignment or security interest granted or
purported to be granted hereby or to enable the Administrative Agent to exercise
and enforce its rights and remedies hereunder with respect to any Collateral.
Without limiting the generality of the foregoing, each Pledgor will: (i) if any
Collateral (other than dividends or distributions in respect of capital stock
that the applicable Pledgor is permitted to retain pursuant to Section 8) shall
be evidenced by a promissory note or other instrument, deliver and pledge to the
Administrative Agent hereunder such note or instrument duly indorsed and
accompanied by duly executed instruments of transfer or assignment, all in form
and substance satisfactory to the Administrative Agent; and (ii) execute and
file such financing or continuation statements, or amendments thereto, and such
other instruments or notices, as may be necessary or desirable, or as the
Administrative Agent may request, in order to perfect and preserve the pledge,
assignment and security interest granted or purported to be granted hereby.

                  (b)      Each Pledgor hereby authorizes the Administrative
Agent to file one or more financing or continuation statements, and amendments
thereto, relating to all or any part of the Collateral without the signature of
such Pledgor where permitted by law. A photocopy or other reproduction of this
Agreement or any financing statement covering the Collateral or any part thereof
shall be sufficient as a financing statement where permitted by law.

                  (c)      Each Pledgor will furnish to the Administrative Agent
from time to time statements and schedules further identifying and describing
the Collateral and such other reports in connection with the Collateral as the
Administrative Agent may reasonably request, all in reasonable detail.

SECTION 7. PLACE OF PERFECTION; RECORDS; COLLECTION OF RECEIVABLES. (a) Each
Pledgor shall keep its chief place of business and chief executive office and
the office where it keeps its records concerning the Collateral, the address
specified in Section 5(a) for each Pledgor or, upon 10 days' prior written
notice to the Administrative Agent, at such other locations in a jurisdiction
where all actions required by Section 6 shall have been taken with respect to
the Collateral.

                                       5
<PAGE>   122

SECTION 8. VOTING RIGHTS; DIVIDENDS; ETC. (a) So long as no Event of Default
shall have occurred and be continuing:

                  (i)      Each Pledgor shall be entitled to exercise any and
         all voting and other consensual rights pertaining to the Security
         Collateral pledged by such Pledgor hereunder or any part thereof for
         any purpose not inconsistent with the terms of this Agreement or the
         other Loan Documents.

                  (ii)     Each Pledgor shall be entitled to receive and retain
         any and all dividends, interest and other distributions paid in respect
         of the Security Collateral pledged by such Pledgor hereunder; provided,
         however, that any and all stock certificates or promissory notes
         received or otherwise distributed in respect of, or in exchange for,
         any Security Collateral, shall be, and shall be forthwith delivered to
         the Administrative Agent to hold as, Security Collateral and shall, if
         received by any such Pledgor, be received in trust for the benefit of
         the Administrative Agent, be segregated from the other property of such
         Pledgor and be forthwith delivered to the Administrative Agent as
         Security Collateral in the same form as so received (with any necessary
         indorsement).

                  (iii)    The Administrative Agent shall execute and deliver
         (or cause to be executed and delivered) to each Pledgor all such
         proxies and other instruments as each such Pledgor may reasonably
         request for the purpose of enabling such Pledgor to exercise the voting
         and other rights that it is entitled to exercise pursuant to paragraph
         (i) above and to receive the dividends or interest payments that it is
         authorized to receive and retain pursuant to paragraph (ii) above.

                  (b)      Upon the occurrence and during the continuance of an
         Event of Default:

                  (i)      Upon notice to such Pledgor by the Administrative
         Agent, all rights of a Pledgor (x) to exercise or refrain from
         exercising the voting and other consensual rights that it would
         otherwise be entitled to exercise pursuant to Section 8(a)(i) shall
         cease and (y) to receive the dividends, interest and other
         distributions that it would otherwise be authorized to receive and
         retain pursuant to Section 8(a)(ii) shall automatically cease, and all
         such rights shall thereupon become vested in the Administrative Agent,
         which shall thereupon have the sole right to exercise or refrain from
         exercising such voting and other consensual rights and to receive and
         hold as Security Collateral such dividends, interest and other
         distributions.

                  (ii)     All dividends, interest and other distributions that
         are received by a Pledgor contrary to the provisions of paragraph (i)
         of this Section 8(b) shall be received in trust for the benefit of the
         Administrative Agent, shall be segregated from other funds of such
         Pledgor and shall be forthwith paid over to the Administrative Agent as
         Security Collateral in the same form as so received (with any necessary
         indorsement).

                                       6
<PAGE>   123

SECTION 9. TRANSFERS AND OTHER LIENS; ADDITIONAL SHARES. (a) Except in a
transaction by a Pledgor permitted by the Credit Agreement, each Pledgor shall
not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of,
or grant any option with respect to, any of the Collateral, or (ii) create or
suffer to exist any Lien upon or with respect to any of the Collateral except
for the pledge, assignment and security interest created by this Agreement.

                  (b)      Each Pledgor shall cause each issuer of the Pledged
Shares not to issue any stock or other securities in substitution for the
Pledged Shares issued by such issuer, except to such Pledgor, and each such
Pledgor shall pledge hereunder, immediately upon its acquisition (directly or
indirectly) thereof, any and all additional shares of stock or other securities
of each issuer of the Pledged Shares issued to or acquired by it.

SECTION 10. ADMINISTRATIVE AGENT APPOINTED ATTORNEY-IN-FACT. Each Pledgor hereby
irrevocably appoints the Administrative Agent such Pledgor's attorney-in-fact,
with full authority in the place and stead of such Pledgor and in the name of
such Pledgor or otherwise, from time to time during the continuance of an Event
of Default in the Administrative Agent's discretion, to take any action and to
execute any instrument that the Administrative Agent may deem necessary or
advisable to accomplish the purposes of this Agreement, including, without
limitation:

                  (a)      to ask for, demand, collect, sue for, recover,
         compromise, receive and give acquittance and receipts for moneys due
         and to become due under or in respect of any of the Collateral,

                  (b)      to receive, indorse and collect any drafts or other
         instruments and documents, in connection with clause (a) above, and

                  (c)      to file any claims take any action or institute any
         proceedings that the Administrative Agent may deem necessary or
         desirable for the collection of any of the Collateral or otherwise to
         enforce compliance with the terms and conditions of any Assigned
         Agreement or the rights of the Administrative Agent with respect to any
         of the Collateral.

SECTION 11. ADMINISTRATIVE AGENT MAY PERFORM. If any Pledgor fails to perform
any agreement contained herein, the Administrative Agent may itself perform, or
cause performance of, such agreement, and the expenses of the Administrative
Agent incurred in connection therewith shall be payable by such Pledgor under
Section 14(b).

SECTION 12. THE ADMINISTRATIVE AGENT'S DUTIES. The powers conferred on the
Administrative Agent hereunder are solely to protect its interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.
Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually received by it hereunder, the

                                       7
<PAGE>   124

Administrative Agent shall have no duty as to any Collateral, as to ascertaining
or taking action with respect to calls, conversions, exchanges, maturities,
tenders or other matters relative to any Security Collateral, whether or not the
Administrative Agent or any Secured Party has or is deemed to have knowledge of
such matters, or as to the taking of any necessary steps to preserve rights
against any parties or any other rights pertaining to any Collateral. The
Administrative Agent shall be deemed to have exercised reasonable care in the
custody and preservation of any Collateral in its possession if such Collateral
is accorded treatment substantially equal to that which NationsBank accords its
own property.

SECTION 13. REMEDIES. If any Event of Default shall have occurred and be
continuing:

                  (a)      The Administrative Agent may exercise in respect of
         the Collateral, in addition to other rights and remedies provided for
         herein or otherwise available to it, all the rights and remedies of a
         secured party upon default under the N.Y. Uniform Commercial Code
         (whether or not the N.Y. Uniform Commercial Code applies to the
         affected Collateral) and also may (i) require each Pledgor to, and each
         Pledgor hereby agrees that it will at its expense and upon request of
         the Administrative Agent forthwith, assemble all or part of the
         Collateral as directed by the Administrative Agent and make it
         available to the Administrative Agent at a place to be designated by
         the Administrative Agent that is reasonably convenient to both parties
         and (ii) without notice except as specified below, sell the Collateral
         or any part thereof in one or more parcels at public or private sale,
         at any of the Administrative Agent's offices or elsewhere, for cash, on
         credit or for future delivery, and upon such other terms as the
         Administrative Agent may deem commercially reasonable. Each Pledgor
         agrees that, to the extent notice of sale shall be required by law, at
         least ten days' notice to such Pledgor of the time and place of any
         public sale or the time after which any private sale is to be made
         shall constitute reasonable notification. The Administrative Agent
         shall not be obligated to make any sale of Collateral regardless of
         notice of sale having been given. The Administrative Agent may adjourn
         any public or private sale from time to time by announcement at the
         time and place fixed therefor, and such sale may, without further
         notice, be made at the time and place to which it was so adjourned.

                  (b)      All cash proceeds received by the Administrative
         Agent in respect of any sale of, collection from, or other realization
         upon all or any part of the Collateral may, in the discretion of the
         Administrative Agent, be held by the Administrative Agent as collateral
         for, and/or then or at any time thereafter applied (after payment of
         any amounts payable to the Administrative Agent pursuant to Section 14)
         in whole or in part by the Administrative Agent for the ratable benefit
         of the Secured Parties against, all or any part of the Secured
         Obligations in such order as the Administrative Agent shall elect. Any
         surplus of such cash or cash proceeds held by the Administrative Agent
         and remaining

                                       8
<PAGE>   125

         after payment in full of all the Secured Obligations shall be paid over
         to the applicable Pledgor or to whomsoever may be lawfully entitled to
         receive such surplus.

SECTION 14. INDEMNITY AND EXPENSES. (a) Each Pledgor agrees to indemnify the
Administrative Agent from and against any and all claims, losses and liabilities
growing out of or resulting from this Agreement (including, without limitation,
enforcement of this Agreement), except claims, losses or liabilities resulting
from the Administrative Agent's gross negligence or willful misconduct.

                  (b)      The Borrower will upon demand pay to the
         Administrative Agent the amount of any and all reasonable expenses,
         including the reasonable fees and expenses of its counsel and of any
         experts and agents, that the Administrative Agent may incur in
         connection with (i) the administration of this Agreement, (ii) the
         custody, preservation, use or operation of, or the sale of, collection
         from or other realization upon, any of the Collateral, (iii) the
         exercise or enforcement of any of the rights of the Administrative
         Agent or the Lenders hereunder or (iv) the failure by any Pledgor to
         perform or observe any of the provisions hereof.

SECTION 15. SECURITY INTEREST ABSOLUTE. The obligations of each Pledgor under
this Agreement are independent of the Secured Obligations, and a separate action
or actions may be brought and prosecuted against any such Pledgor enforce this
Agreement, irrespective of whether any action is brought against such Pledgor or
whether such Pledgor is joined in any such action or actions. All rights of the
Administrative Agent and the pledge, assignment and security interest hereunder,
and all obligations of the any such Pledgor hereunder, shall be absolute and
unconditional, irrespective of:

                  (a)      any lack of validity or enforceability of any Loan
         Document, any Bank Hedge Agreement or any other agreement or instrument
         relating thereto;

                  (b)      any change in the time, manner or place of payment
         of, or in any other term of, all or any of the Secured Obligations or
         any other amendment or waiver of or any consent to any departure from
         any Loan Document or any Bank Hedge Agreement, including, without
         limitation, any increase in the Secured Obligations resulting from the
         extension of additional credit to the Pledgor or any of its
         subsidiaries or otherwise;

                  (c)      any taking, exchange, release or non-perfection of
         any other collateral, or any taking, release or amendment or waiver of
         or consent to departure from any guaranty, for all or any of the
         Secured Obligations;

                  (d)      any manner of application of collateral, or proceeds
         thereof, to all or any of the Secured Obligations, or any manner of
         sale or other disposition of any collateral for all or any of the
         Secured Obligations or any other assets of any Pledgor or any of its
         subsidiaries;

                                       9
<PAGE>   126

                  (e)      any change, restructuring or termination of the
         corporate structure or existence of any Pledgor or any of its
         subsidiaries; or

                  (f)      any other circumstance that might otherwise
         constitute a defense available to, or a discharge of, any Pledgor or a
         third party grantor of a security interest.

SECTION 16. AMENDMENTS; WAIVERS; ETC. (a) No amendment or waiver of any
provision of this Agreement, and no consent to any departure by any Pledgor
herefrom, shall in any event be effective unless the same shall be in writing
and signed by the Administrative Agent, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

                  (b)      No failure on the part of the Administrative Agent to
exercise, and no delay in exercising any right hereunder, shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right
preclude any other or further exercise thereof or the exercise of any other
right.

                  (c)      Upon the execution and delivery by any Person of a
supplement to this Agreement, in each case in substantially the form of Exhibit
A hereto (each a "Pledge Agreement Supplement"), (i) such Person shall be
referred to as an "Additional Pledgor" and shall be and become a Pledgor, and
each reference in this Agreement to an "Additional Pledgor" or a "Pledgor" shall
also mean and be a reference to such Additional Pledgor and each reference in
any other Loan Document to a "Pledgor" or a "Loan Party" shall also mean and be
a reference to such Additional Pledgor, and (ii) the supplements attached to
each Pledge Agreement Supplement shall be incorporated into and become a part of

                  SECTION 18. CONTINUING SECURITY INTEREST; ASSIGNMENTS UNDER
THE CREDIT AGREEMENT. This Agreement shall create a continuing security interest
in the Collateral and shall (a) remain in full force and effect until the later
of the payment in full in cash of the Secured Obligations and the Termination
Date, (b) be binding upon each Pledgor, its successors and assigns and (c)
inure, together with the rights and remedies of the Administrative Agent
hereunder, to the benefit of the Administrative Agent, the Lenders and their
respective successors, transferees and assigns (in each case subject to the
provisions of Section 19). Without limiting the generality of the foregoing
clause (c), any Lender may assign or otherwise transfer all or any portion of
its rights and obligations under the Credit Agreement (including, without
limitation, all or any portion of its Commitment, and the Advances owing to it
and the Note or Notes held by it to any other Person), and such other Person
shall thereupon become vested with all the benefits in respect thereof granted
to such Lender herein or otherwise, in each case as provided in Section 8.07 of
the Credit Agreement.

SECTION 19. RELEASE AND TERMINATION. (a) Upon any sale, lease, transfer or other
disposition of any item of Collateral in accordance with the terms of the Loan
Documents, the security interest hereunder in such Collateral shall
automatically be terminated and released and the Administrative Agent will, at
the expense of the Pledgor pledging such item, execute and deliver to such
Pledgor such documents as such Pledgor shall reasonably request to evidence the
release of such item of Collateral from the assignment and security interest
granted hereby; provided, however, that (i) at the time of such request and such
release no Default shall have occurred and be continuing, and (ii) the proceeds
of any such sale, lease, transfer or other disposition required to be applied in
accordance with Section 2.05 of the Credit Agreement shall be paid to, or in
accordance with the instructions of, the Administrative Agent at the closing.

                  (b)      Upon the later of the payment in full in cash of the
Secured Obligations (other than any Obligations relating to any Bank Hedge
Agreement) and the Termination Date, the pledge, assignment and security
interest granted hereby shall terminate and all rights to the Collateral shall
revert to the Pledgor pledging such item. Upon any such termination, the
Administrative Agent will, at the expense of the Pledgor pledging such item,
execute and deliver to such Pledgor such documents as such Pledgor shall
reasonably request to evidence such termination.

hereunder, in respect of any particular Collateral are governed by the laws of a
jurisdiction other than the State of New York.

"Guarantors"), in favor of the Secured Parties (as defined in the Credit
Agreement referred to below).

                  PRELIMINARY STATEMENT. MedCath Intermediate Holdings, Inc., a
Delaware corporation (the "Borrower"), has entered into a Credit Agreement dated
as of July 31, 1998 (said Agreement, as it may hereafter be amended,
supplemented or otherwise modified from time to time, being the "Credit
Agreement"; the terms defined therein and not otherwise defined herein being
used herein as therein defined) with the banks, financial institutions and other
institutional lenders party thereto (the "Lender Parties", NationsBank, N.A.
("NationsBank") as administrative agent (in such capacity, the "Administrative
Agent"), NationsBank as collateral agent (in such capacity, the "Collateral
Agent"), and NationsBanc Montgomery Securities LLC, as arranger and syndication
agent. It is a condition precedent to the making of Advances and the issuance of
Letters of Credit by the Lender Parties under the Credit Agreement that each
Guarantor (as a Subsidiary of the Borrower) shall have executed and delivered
this Guaranty.

                  NOW, THEREFORE, in consideration of the premises and in order
to induce the Lender Parties to make Advances and to issue Letters of Credit
under the Credit Agreement from time to time and the Hedge Banks to enter into
Bank Hedge Agreements from time to time, each Guarantor hereby agrees as
follows:

         SECTION 21.       GUARANTY; LIMITATION OF LIABILITY. (a) Each Guarantor
hereby unconditionally and irrevocably guarantees the punctual payment when due,
whether at stated maturity, by acceleration or otherwise, of all Obligations of
the Borrower now or hereafter existing under the Loan Documents and under the
Bank Hedge Agreements, whether for, principal, interest, fees, expenses or
otherwise (such Obligations being the "Guaranteed Obligations"), and agrees to
pay any and all expenses (including counsel fees and expenses) incurred by the
Administrative Agent or any other Secured Party in enforcing any rights under
this Guaranty. Without limiting the generality of the foregoing, each
Guarantor's liability shall extend to all amounts that constitute part of the
Guaranteed Obligations and would be owed by the Borrower to the Administrative
Agent or any other Secured Party under the Loan Documents or the Bank Hedge
Agreements but for the fact that they are unenforceable or not allowable due to
the existence of a bankruptcy, reorganization or similar proceeding involving
the Borrower.

                  (B)      EACH GUARANTOR, AND BY ITS ACCEPTANCE OF THIS
GUARANTY, THE ADMINISTRATIVE AGENT AND EACH OTHER SECURED PARTY, HEREBY CONFIRMS
THAT IT IS THE INTENTION OF ALL SUCH PARTIES THAT THIS GUARANTY NOT CONSTITUTE A
FRAUDULENT TRANSFER OR CONVEYANCE FOR PURPOSES OF BANKRUPTCY LAW, THE UNIFORM
FRAUDULENT CONVEYANCE ACT, THE UNIFORM TRANSFER ACT OR ANY SIMILAR FEDERAL OR
STATE LAW TO THE EXTENT APPLICABLE TO THIS

<PAGE>   142

GUARANTY. TO EFFECTUATE THE FOREGOING INTENTION, THE ADMINISTRATIVE AGENT, THE
OTHER SECURED PARTIES AND THE GUARANTORS HEREBY IRREVOCABLY AGREE THAT THE
OBLIGATIONS OF EACH GUARANTOR UNDER THIS GUARANTY SHALL BE LIMITED TO THE
MAXIMUM AMOUNT AS WILL, AFTER GIVING EFFECT TO SUCH MAXIMUM AMOUNT AND ALL OTHER
CONTINGENT AND FIXED LIABILITIES OF SUCH GUARANTOR (OTHER THAN GUARANTIES OF
SUCH GUARANTOR IN RESPECT OF SUBORDINATED DEBT) THAT ARE RELEVANT UNDER SUCH
LAWS, AND AFTER GIVING EFFECT TO ANY COLLECTIONS FROM, RIGHTS TO RECEIVE
CONTRIBUTIONS FROM OR PAYMENT MADE BY OR ON BEHALF OF ANY OTHER GUARANTOR IN
RESPECT OF THE OBLIGATIONS OF SUCH OTHER GUARANTOR UNDER THIS GUARANTY OR ANY
OTHER GUARANTY, RESULT IN THE OBLIGATIONS OF SUCH GUARANTOR UNDER THIS GUARANTY
NOT CONSTITUTING A FRAUDULENT TRANSFER OR CONVEYANCE. FOR PURPOSES HEREOF,
"BANKRUPTCY LAW" MEANS TITLE II, U.S. CODE, OR ANY SIMILAR FEDERAL OR STATE LAW
FOR THE RELIEF OF DEBTORS.

                  (c)      Each Guarantor agrees that in the event any payment
shall be required to be made to the Secured Parties under this Guaranty or any
other guaranty, such Guarantor will contribute, to the maximum extent permitted
by law, such amounts to each other Guarantor and each other guarantor so as to
maximize the aggregate amount paid to the Secured Parties under the Loan
Documents.

         SECTION 22.       GUARANTY ABSOLUTE. Each Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms of the
Loan Documents and the Bank Hedge Agreements, regardless of any law, regulation
or order now or hereafter in effect in any jurisdiction affecting any of such
terms or the rights of the Agent or any other Secured Party with respect
thereto. The Obligations of each Guarantor under this Guaranty are independent
of the Guaranteed Obligations or any other Obligations of any other Loan Party
under the Loan Documents or the Bank Hedge Agreements, and a separate action or
actions may be brought and prosecuted against each Guarantor to enforce this
Guaranty, irrespective of whether any action is brought against the Borrower or
any other Loan Party or whether the Borrower or any other Loan Party is joined
in any such action or actions. The liability of each Guarantor under this
Guaranty shall be irrevocable, absolute and unconditional irrespective of, and
each Guarantor hereby irrevocably waives any defenses it may now or hereafter
have in any way relating to, any or all of the following:

                           (a)      any lack of validity or enforceability of
                  any Loan Document, any Bank Hedge Agreement or any agreement
                  or instrument relating thereto;

                           (b)      any change in the time, manner or place of
                  payment of, or in any other term of, all or any of the
                  Guaranteed Obligations or any other Obligations of any other
                  Loan Party under the Loan Documents or the Bank Hedge
                  Agreements, or any other amendment or waiver of or any consent
                  to departure from any Loan Document or any Bank Hedge
                  Agreement, including, without limitation, any increase in the
                  Guaranteed Obligations resulting from the extension of
                  additional credit to the Borrower or any of its Subsidiaries
                  or otherwise;

                           (c)      any taking, exchange, release or
                  non-perfection of any Collateral, or any taking, release or
                  amendment or waiver of or consent to departure from any other
                  guaranty, for all or any of the Guaranteed Obligations;

<PAGE>   143

                           (d)      any manner of application of Collateral, or
                  proceeds thereof, to all or any of the Guaranteed Obligations,
                  or any manner of sale or other disposition of any Collateral
                  for all or any of the Guaranteed Obligations or any other
                  Obligations of any other Loan Party under the Loan Documents
                  or the Bank Hedge Agreements or any other assets of the
                  Borrower or any of its Subsidiaries;

                           (e)      any change, restructuring or termination of
                  the corporate structure or existence of the Borrower or any of
                  its Subsidiaries;

                           (f)      any failure of any Secured Party to disclose
                  to the Borrower or any Guarantor any information relating to
                  the financial condition, operations, properties or prospects
                  of any other Loan Party now or in the future known to any
                  Secured Party (such Guarantor waiving any duty on the part of
                  the Secured Parties to disclose such information); or

                           (g)      any other circumstance (including, without
                  limitation, any statute of limitations) or any existence of or
                  reliance on any representation by the Administrative Agent or
                  any other Secured Party that might otherwise constitute a
                  defense available to, or a discharge of, the Borrower, any
                  Guarantor or any other guarantor or surety.

This Guaranty shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by any Secured Party or any other Person upon the
insolvency, bankruptcy or reorganization of the Borrower or any other Loan Party
or otherwise, all as though such payment had not been made.

         SECTION 23.       WAIVERS AND ACKNOWLEDGMENTS. (a) Each Guarantor
hereby waives promptness, diligence, notice of acceptance and any other notice
with respect to any of the Guaranteed Obligations and this Guaranty and any
requirement that the Administrative Agent or any other Secured Party protect,
secure, perfect or insure any Lien or any property subject thereto or exhaust
any right or take any action against the Borrower or any other Person or any
Collateral.

                  (b)      Each Guarantor hereby waives any right to revoke this
Guaranty, and acknowledges that this Guaranty is continuing in nature and
applies to all Guaranteed Obligations, whether existing now or in the future.

<PAGE>   144

                  (c)      Each Guarantor acknowledges that it will receive
substantial direct and indirect benefits from the financing arrangements
contemplated by the Loan Documents and that the waivers set forth in this
Section 3 are knowingly made in contemplation of such benefits.

         SECTION 24.       SUBROGATION. Each Guarantor will not exercise any
rights that it may now or hereafter acquire against the Borrower or any other
insider guarantor that arise from the existence, payment, performance or
enforcement of the Guarantor's Obligations under this Guaranty or any other Loan
Document or any Bank Hedge Agreement, including, without limitation, any right
of subrogation, reimbursement, exoneration, contribution or indemnification and
any right to participate in any claim or remedy of the Administrative Agent or
any other Secured Party against the Borrower or any other insider guarantor or
any Collateral, whether or not such claim, remedy or right arises in equity or
under contract, statute or common law, including, without limitation, the right
to take or receive from the Borrower or any other insider guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim, remedy or right, unless and until
all of the Obligations and all other amounts payable under this Guaranty shall
have been paid in full in cash and the Commitments shall have expired or
terminated. If any amount shall be paid to any Guarantor in violation of the
preceding sentence at any time prior to the later of the payment in full in cash
of the Guaranteed Obligations and all other amounts payable under this Guaranty
and the Termination Date, such amount shall be held in trust for the benefit of
the Administrative Agent and the other Secured Parties and shall forthwith
either (i) be paid to the Administrative Agent to be credited and applied to the
Guaranteed Obligations and all other amounts payable under this Guaranty,
whether matured or unmatured, in accordance with the terms of the Loan Documents
and the Bank Hedge Agreements, or (ii) be held as Collateral for any Guaranteed
Obligations or other amounts payable under this Guaranty thereafter arising. If
(i) any Guarantor shall make payment to the Administrative Agent or any other
Secured Party of all or any part of the Guaranteed Obligations, (ii) all of the
Guaranteed Obligations and all other amounts payable under this Guaranty shall
be paid in full in cash and (iii) the Termination Date shall have occurred, the
Administrative Agent and the other Secured Parties will, at such Guarantor's
request and expense, execute and deliver to such Guarantor appropriate
documents, without recourse and without representation or warranty, necessary to
evidence the transfer by subrogation to such Guarantor of an interest in the
Guaranteed Obligations resulting from such payment by such Guarantor.

         SECTION 25.       TAXES. (a) Any and all payments by a Guarantor
hereunder or under any of the other Loan Documents shall be made, in accordance
with Section 2.12 of the Credit Agreement, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding, in
the case of each Lender Party and each Agent, taxes that are imposed as a result
of a present or former connection between the Lender Party or the Administrative
Agent and the jurisdiction of the Governmental Authority imposing such taxes or
any political subdivision or taxing authority thereof or therein (other than a
connection relating to or arising solely from the Lender Party or

<PAGE>   145

the Administrative Agent holding a Working Capital Note or having executed,
delivered or performed its obligations or received or otherwise collected
payment under, or enforced or otherwise exercised its rights under this
Agreement or any of the other Loan Documents) (all such nonexcluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities in respect of
payments hereunder or under the other Loan Documents being, collectively,
"Taxes"). If a Guarantor shall be required under applicable Requirements of Law
to deduct any Taxes from or in respect of any sum payable hereunder or under any
Working Capital Note to any Lender Party or any Agent, (i) the sum payable shall
be increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
5) such Lender Party or such Agent, as the case may be, receives an amount equal
to the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant taxation authority or other Governmental
Authority in accordance with applicable Requirements of Law.

                  (b)      In addition, each Guarantor shall pay any present or
future Other Taxes (as defined in Section 2.12(b) of the Credit Agreement).

                  (c)      Each Guarantor shall indemnify each Lender Party and
each Agent for the full amount of Taxes and Other Taxes, and for the full amount
of taxes of any kind imposed by any jurisdiction on amounts payable under this
Section 5, imposed on or paid by such Lender Party or such Agent, as the case
may be, and any liability (including penalties, additions to tax, interest and
expenses) arising therefrom or with respect thereto. The indemnity by such
Guarantor provided for in this subsection (c) shall apply and be made whether or
not the Taxes or Other Taxes for which indemnification hereunder is sought have
been correctly or legally asserted; provided, however, that such Lender or such
Agent seeking such indemnification shall take all reasonable actions (consistent
with its internal policy and legal and regulatory restrictions) requested by the
Borrower to assist the Borrower in recovering the amounts paid thereby pursuant
to this subsection (c) from the relevant taxation authority or other
Governmental Authority. Amounts payable by a Guarantor under the indemnity set
forth in this subsection (c) shall be paid within 30 days from the date on which
the applicable Lender or Agent, as the case may be, makes written demand
therefor.

                  (d)      If the Administrative Agent or any Lender Party
receives a refund in respect of Taxes paid by a Guarantor, which in the
reasonable judgment of such Lender Party is allocable to such payment, it shall
promptly pay such refund, together with any other amounts paid by such Guarantor
in connection with such refunded Taxes, to such Guarantor, net of all
out-of-pocket expenses of such Lender Party incurred in obtaining such refund,
provided, that such Guarantor agrees to promptly return such refund to the
Administrative Agent or the applicable Lender Party, as the case may be, if it
receives notice from the Administrative Agent or the applicable Lender Party
that such Administrative Agent or Lender Party is required to repay such refund.

<PAGE>   146

                  (e)      Within 30 days after the date of any payment of
Taxes, the relevant Guarantor shall furnish to the Administrative Agent, at its
address referred to in Section 8.02 of the Credit Agreement, the original or a
certified copy of a receipt evidencing payment thereof, to the extent such a
receipt is issued therefor, or other written proof of payment thereof that is
reasonably satisfactory to the Administrative Agent.

                  (f)      Each Lender Party organized under the laws of a
jurisdiction outside the United States shall, on or prior to the date of its
execution and delivery of the Credit Agreement in the case of each Initial
Lender or Initial Issuing Bank, as the case may be, and on the date of the
Assignment and Acceptance pursuant to which it becomes a Lender Party in the
case of each other Lender Party, and from time to time thereafter as reasonably
requested in writing by any Guarantor (but only so long thereafter as such
Lender Party remains lawfully able to do so), provide each of the Administrative
Agent and such Guarantor with two original Internal Revenue Service forms 1001
or 4224 or any successor or other form prescribed by the Internal Revenue
Service, certifying that such Lender Party is exempt from or entitled to a
reduced rate of United States withholding tax on payments pursuant to this
Agreement or the other Loan Documents. If the forms provided by a Lender Party
at the time such Lender Party first becomes a party to this Agreement or at the
time the Lender Party changes the jurisdiction of its Applicable Lending Office
or designates a different Applicable Lending Office indicates a United States
interest withholding tax rate in excess of zero, withholding tax at such rate
shall be considered excluded from Taxes unless and until such Lender Party
provides the appropriate form certifying that a lesser rate applies, whereupon
withholding tax at such lesser rate only shall be considered excluded from Taxes
for periods governed by such form; provided, however, that, if at the date of a
change in the jurisdiction of the Applicable Lending Office or designation of a
new Applicable Lending Office of a Lender Party, such Lender Party was entitled
to payments under subsection (a) in respect of withholding tax with respect to
interest paid immediately before the change in the Applicable Lending Office,
then, to such extent, the term Taxes shall include (in addition to withholding
taxes that may be imposed in the future or other amounts otherwise includable in
Taxes) withholding tax, if any, applicable with respect to such new Applicable
Lending Office on such date; provided further that, if at the date of the
Assignment and Acceptance pursuant to which a Lender Party becomes a party to
this Agreement, the Lender Party assignor was entitled to payments under
subsection (a) in respect of withholding tax with respect to interest paid at
such date, then, to such extent, the term Taxes shall include (in addition to
withholding taxes that may be imposed in the future or other amounts otherwise
includable in Taxes) withholding tax, if any, applicable with respect to the
Lender Party assignee on such date.

                  (g)      For any period with respect to which a Lender Party
has failed to provide the Loan Parties with the appropriate form, certificate or
other document described in subsection (e) of this Section 5 (other than if such
failure is due to a change in the applicable Requirements of Law, or in the
interpretation or application thereof, occurring after the date on which a form,
certificate or other document originally was required to be provided or if such
form, certificate or other document otherwise is not required under subsection
(e) of this Section

<PAGE>   147

5), such Lender Party shall not be entitled to indemnification under subsection
(a) or (c) of this Section 5 with respect to Taxes imposed by the United States
by reason of such failure; provide, however, that should a Lender Party become
subject to Taxes because of its failure to deliver a form, certificate or other
document required hereunder, each Guarantor shall, at such Lender Party's sole
expense, take such steps as such Lender Party shall reasonably request to assist
such Lender Party in recovering such Taxes.

                  (h)      Any Lender Party claiming any additional amounts
payable pursuant to this Section 5 agrees to use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Applicable Lending Office or designate a different
Applicable Lending Office if the making of such a change or designation would
avoid the need for, or reduce the amount of, any such additional amounts that
may thereafter accrue, provided that such change or designation is made on terms
that such Lender Party and its Applicable Lending Office suffer no economic,
legal or regulatory disadvantage, with the object of avoiding the consequence of
the event giving rise to the operation of subsection (a) or (c) above.

         SECTION 26.       COVENANTS. Each Guarantor covenants and agrees that,
so long as any part of the Guaranteed Obligations shall remain unpaid, any
Letter of Credit shall be outstanding, or any Lender Party shall have any
Commitment, such Guarantor will, unless the Required Lenders shall otherwise
consent in writing, perform or observe all of the terms, covenants and
agreements that the Loan Documents either (i) state such Guarantor shall perform
or observe or (ii) state that the Borrower is to cause such Guarantor to perform
or observe, in each case subject to the provisions thereof including applicable
grace periods with respect thereto.

         SECTION 27.       AMENDMENTS. ETC. (a) No amendment or waiver of any
provision of this Guaranty and no consent to any departure by any Guarantor
therefrom shall in any event be effective unless the same shall be in accordance
with the provisions of Section 8.01 of the Credit Agreement.

                  (b)      Upon the execution and delivery by any Person of a
supplemental guaranty in substantially the form of Exhibit A hereto (each, a
"Guaranty Supplement"), such Person shall be referred to as an "Additional
Guarantor" and shall be and become a Guarantor hereunder and each reference in
this Guaranty to a "Guarantor" shall also mean and be a reference to such
Additional Guarantor and each reference in any other Loan Document to a
"Guarantor" shall also mean and be a reference to such Additional Guarantor.

         SECTION 28.       NOTICES. ETC. All notices and other communications
provided for hereunder shall be in writing (including telegraphic, telecopy or
telex communication) and mailed, telegraphed, telecopied, telexed or delivered
to it, if to the Guarantor, addressed to it at the addresses listed for such
Guarantor on the signature pages hereof (or in the applicable Guaranty
Supplement), if to the Administrative Agent or any Lender Party, at its address
specified in the

<PAGE>   148

Credit Agreement, or as to any party at such other address as shall be
designated by such party in a written notice to each other party. All such
notices and other communications shall, when mailed, telegraphed, telecopied or
telexed, be effective when deposited in the malls, delivered to the telegraph
company, transmitted by telecopier or confirmed by telex answerback,
respectively.

         SECTION 29.       NO WAIVER: REMEDIES. No failure on the part of the
Administrative Agent or any other Secured Party to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

         SECTION 30.       RIGHT OF SET-OFF. Upon (a) the occurrence and during
the continuance of any Event of Default and (b) the making of the request or the
granting of the consent specified by Section 6.01 of the Credit Agreement to
authorize the Administrative Agent to declare the Notes due and payable pursuant
to the provisions of said Section 6.01, each Lender Party and each of its
respective Affiliates is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender Party or such Affiliate to
or for the credit or the account of any Guarantor against any and all of the
Obligations of such Guarantor now or hereafter existing under this Guaranty,
whether or not such Lender Party shall have made any demand under this Guaranty
and although such Obligations may be unmatured. Each Lender Party agrees
promptly to notify the applicable Guarantor after any such set-off and
application; provided, however, that the failure to give such notice shall not
affect the validity of such set-off and application. The rights of each Lender
Party and its respective Affiliates under this Section are in addition to other
rights and remedies (including, without limitation, other rights of set-off)
that such Lender Party and its respective Affiliates may have.

         SECTION 31.       CONTINUING GUARANTY; ASSIGNMENTS UNDER THE CREDIT
AGREEMENT. This Guaranty is a continuing guaranty and shall (a) remain in full
force and effect until the later of the payment in full in cash of the
Guaranteed Obligations and all other amounts payable under this Guaranty and the
Termination Date, (b) be binding upon each Guarantor, its successors and assigns
and (c) inure to the benefit of and be enforceable by the Administrative Agent
and the other Secured Parties and their successors, transferees and assigns;
provided, however, that the obligations of any Guarantor hereunder, and the
effectiveness of the provisions hereof with respect to such Guarantor, shall
automatically terminate and be released upon the sale, transfer or other
disposition of the Capital Stock of such Guarantor so long as (x) such sale,
transfer or other disposition is consummated in accordance with the terms of the
Credit Agreement and (y) as a result of such sale, transfer or other disposition
such Guarantor Subsidiary becomes a Person that no longer meets the criteria of
a Guarantor Subsidiary set forth in the definition thereof. Without limiting the
generality of the foregoing clause (c), any Secured Party may assign or
otherwise transfer all or any portion of its rights and obligations under the
Credit Agreement (including,

<PAGE>   149

without limitation, all or any portion of its Commitment, the Advances owing to
it and the Note or Notes held by it) to any other Person, and such other Person
shall thereupon become vested with all the benefits in respect thereof granted
to such Secured Party herein or otherwise, in each case as and to the extent
provided in Section 8.07 of the Credit Agreement.

         SECTION 32.       GOVERNING LAW; JURISDICTION: WAIVER OF JURY TRIAL.
ETC. (a) This Guaranty shall be governed by, and construed in accordance with,
the laws of the State of New York.

                  (b)      Each Guarantor hereby irrevocably and unconditionally
submits, for itself and its property, to the nonexclusive jurisdiction of any
New York State court or federal court of the United States of America sitting in
New York City, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Guaranty or any of the other Loan
Documents to which it is or is to be a party, or for recognition or enforcement
of any judgment, and each Guarantor hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard
and determined in any such New York State court or, to the extent permitted by
law, in such federal court. Each Guarantor agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Guaranty shall affect any right that any party may otherwise
have to bring any action or proceeding relating to this Guaranty or any of the
other Loan Documents to which it is or is to be a party in the courts of any
jurisdiction.

                  (c)      Each Guarantor irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Guaranty or any of the
other Loan Documents to which it is or is to be a party in any New York State or
federal court. Each Guarantor hereby irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

<PAGE>   150

                  (d)      Each Guarantor hereby irrevocably waives all right to
trial by jury in any action, proceeding or counterclaim (whether based on
contract, tort or otherwise) arising out of or relating to any of the Loan
Documents, the transactions contemplated thereby or the actions of the
Administrative Agent or any other Secured Party in the negotiation,
administration, performance or enforcement thereof.

                  IN WITNESS WHEREOF, each Guarantor has caused this Guaranty to
be duly executed and delivered by its officer thereunto duly authorized as of
the date first above written.

Ladies and Gentlemen:

         Reference is made to the above-captioned Credit Agreement and to the
Subsidiary Guaranty referred to therein (such Subsidiary Guaranty, as in effect
on the date hereof and as it may hereafter be amended, modified or supplemented
from time to time, being the "Subsidiary Guaranty"). The terms defined in the
Subsidiary Guaranty and the Credit Agreement and not otherwise defined herein
are used herein as therein defined.

         The undersigned hereby unconditionally and irrevocably guarantees the
punctual payment when due, whether as stated maturity, by acceleration or
otherwise, of all Obligations of the Borrower now or hereafter existing under
the Loan Documents and the Bank Hedge Agreements, whether for principal,
interest, fees, expenses or otherwise and agrees to pay any and all expenses
(including reasonable counsel fees and expenses) incurred by the Administrative
Agent or any other Secured Party on the terms and subject to the limitations set
forth in the Guaranty as if it were an original party thereto. On and after the
date hereof, each reference in the Subsidiary Guaranty to "Guarantor" shall also
mean and be a reference to the undersigned.

         The undersigned hereby agrees to be bound as a Guarantor by all of the
terms and provisions of the Subsidiary Guaranty to the same extent as each other
Guarantor.

                  AS ADMINISTRATIVE AGENT, THE INITIAL LENDERS AND INITIAL
                  ISSUING BANK REFERRED TO IN THE CREDIT AGREEMENT AND MEDCATH

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

Ladies and Gentlemen:

         We have acted as special counsel to the entities listed on Exhibit A
attached hereto (each individually a "Guarantor" and, collectively, the
"Guarantors") in connection with the Credit Agreement (the "Credit Agreement")
of even date herewith among you, NationsBank Montgomery Securities LLC, as
Arranger and Syndication Agent, and MedCath Intermediate Holdings, Inc. (the
"Borrower") and the other transactions contemplated under the Credit Agreement.

         This opinion is being delivered in accordance with the conditions set
forth in Section 3.01(h)(xi) the Credit Agreement. All capitalized terms not
otherwise defined herein shall have the meanings provided therefor in the Credit
Agreement.

         As such special counsel, we have reviewed the following documents all
dated July 31, 1998:

         1.       the Credit Agreement;

         2.       the Working Capital Notes;

         3.       the Guaranty; and

         4.       the Pledge Agreement.

         The documents described in items 1 through 4 immediately above are
referred to herein as the "Loan Documents."

NationsBank, N.A., as Administrative
Agent and Each of the Lenders

Page 20

         For purposes of the opinions expressed below, we have assumed that all
signatures (other than those of representatives of the Guarantors on the Loan
Documents) on all documents submitted to us are genuine; that all documents
submitted to us as originals are authentic; that all documents submitted to us
as certified copies, telecopies or photocopies conform to the originals of such
documents, which themselves are authentic; that the Loan Documents have been
duly authorized, executed and delivered by each party thereto other than the
Guarantors; that the Loan Documents will be the legal, valid and binding
obligations, enforceable in accordance with their terms, of each party thereto;
that any natural persons executing any of the Loan Documents have legal
capacity; and that all public records reviewed are true and complete. We have
further assumed, without investigation, the following matters:

                  (a)      that the representations and warranties contained in
         the Loan Documents pertaining to factual matters are true and correct
         as set forth therein; and

                  (b)      that any certificate, representation or document
         which we have received from any governmental authority and upon which
         we have relied and which was given or dated earlier than the date of
         this letter continues to remain accurate, insofar as relevant to the
         opinions contained herein, from such earlier date through and including
         the date hereof.

         With respect to the assumptions set forth hereinabove, we hereby advise
you that in the course of our representation, we have not discovered any
condition or fact which would make such assumptions unwarranted.

         In addition, for purposes of giving this opinion, we have examined such
corporate records of the Guarantors, certificates of public officials,
certificates of appropriate officials of the Guarantors, and such other
documents, and have made such inquiries, as we have deemed appropriate.

         In basing certain of the opinions expressed below on "our knowledge,"
the words "our knowledge" signify that, in the course of our representation of
the Guarantors as aforesaid, no information has come to our attention that has
given us conscious awareness that any such opinions are not accurate or that any
of the documents, certificates and information on which we have relied in
expressing any such opinions are not true and complete in all material respects.
The phrase "our knowledge" is limited to the conscious awareness of the lawyers
within our firm who have worked on the transactions contemplated by the Loan
Documents.

         Based upon and subject to the foregoing and the qualifications set
forth below, it is our opinion that as of the date hereof:

                  1.       The Guarantors are corporations duly incorporated and
         validly existing under the laws of the State of North Carolina and each
         such Guarantor has full corporate power to own its assets and conduct
         the business in which it is now engaged and as expressly contemplated
         in the Loan Documents and each has corporate power and authority to
         enter into the Loan Documents to which it is a party and to perform its
         obligations thereunder.

                  2.       Each of the Loan Documents to which a Guarantors is a
         party has been duly authorized and properly executed and delivered
         where required by such Guarantor.

                  3.       Neither the execution or delivery of, nor performance
         by any Guarantor of its obligations under, the Loan Documents (a) does
         or will conflict with, violate or constitute a breach of (i) the
         charter or bylaws of such Guarantor, (ii) any laws, rules or
         regulations applicable to such Guarantor, (iii) to our knowledge, and
         in reliance on the officer's certificate from such Guarantor dated as
         of the date hereof (the "Officer's Certificate"), any agreement to
         which such Guarantor is now a party or by which it or its property is
         bound or (iv) to our knowledge; and in reliance on the Officer's
         Certificate, any judgment, writ, determination, order, decree or
         arbitral award to which such Guarantor is a party or by such Guarantor
         or any of their properties is bound, (b) requires the prior consent of,
         notice to, license from or filing with any Governmental Authority which
         has not been duly obtained or made on or prior to the date hereof, (c)
         to our knowledge, and in reliance on the Officer's Certificate,
         requires the prior consent of, notice to, license from or filing with
         any third party which has not been duly obtained or made on or prior to
         the date hereof, or (d) to our knowledge, and in reliance on the
         Officer's Certificate, does or will result in the creation or
         imposition of any Lien upon or with respect to any of the properties of
         any Guarantor, except for the Liens in your favor expressly created
         pursuant to the Loan Documents.

                  4.       To our knowledge, there is no pending or threatened,
         action, suit, investigation or proceeding before or by any court, or
         governmental department, commission, board, bureau, instrumentality,
         agency or arbitral authority, which calls into question the validity or
         enforceability of the Loan Documents.

                  5.       Assuming (i) attachment of the security interests
         created in the Collateral (as defined in the Pledge Agreement) by the
         Pledge Agreement under New York law (the "Security Interests"), and
         (ii) filing in the offices and places in North Carolina as are
         necessary in order to perfect a security interest in such Collateral,
         the Pledgor Financing Statements (as defined in the Pledge Agreement)
         that will be filed in North Carolina are in proper form to perfect the
         Security Interests covered thereby, to the extent that perfection of a
         security interest in such Collateral is required to be effected by
         filing in North Carolina financing statements under the Uniform
         Commercial Code as in effect in North Carolina (the "UCC").

                  In stating our opinion as to perfection of the Security
         Interests, we have assumed that (i) the chief executive office (within
         the meaning of Section 9-103(3) of the UCC) of each of the Guarantors
         is in Mecklenburg County, North Carolina. In addition, we call to your
         attention that perfection or nonperfection of the Security Interests
         may be subject to the following qualifications:

                  (i)      in the case of all collateral, we call to your
         attention that Article 9 of the UCC requires the filing of appropriate
         continuation statements within the period of six (6) months prior to
         the expiration of five (5) years from the date of the original filings
         (and each fifth year thereafter), in order to maintain the
         effectiveness of the filings referred to in this paragraph;

                  (ii)     in the case of property which becomes collateral
         after the date hereof, Section 552 of the Federal Bankruptcy Code
         limits the extent to which property acquired by a debtor after the
         commencement of a case under the Federal Bankruptcy Code may be subject
         to a security interest arising from a security agreement entered into
         by the debtor before the commencement of such case;

                  (iii)    under Section 9-403(1) of the UCC, a financing
         statement is "filed" if it is presented to the filing officer together
         with tender of the requisite filing fee and accepted by the filing
         officer, whether or not such financing statement is ever properly
         recorded or indexed of record;

                  ((iv)    the applicable provisions of Section 9-104 of the UCC
         provide that Article 9 of the UCC does not apply to collateral of the
         types described therein (including, without limitation, deposit
         accounts);

                  (v)      acquiring and enforcing a perfected security interest
         in proceeds of any collateral may be limited under the circumstances
         described in Section 9-306 of the UCC;

                  (vi)     purchasers of certain collateral may take it free of
         a perfected security interest under circumstances described in Section
         9-307 and 9-308 of the UCC; and

                  (vii)    a perfected security interest in after-acquired
         collateral is subject to the rules contained in Section 9-312 of the
         UCC.

         We call your attention to the fact that the perfection of the security
interests granted by the Pledge Agreement will be terminated (a) as to
collateral consisting of accounts, chattel paper, mobile goods or general
intangibles (other than uncertificated securities) (as such terms are defined in
the UCC), to the extent such perfection is achieved by the filing of financing
statements, four (4) months after the chief executive office of the debtor
granting such security interests is no longer located in Mecklenburg County,
North Carolina, unless new appropriate financing statements are properly filed
before the expiration of such four (4) months, (b) as to any collateral
consisting of goods (as such term is defined in the UCC) which are subsequently
moved to a different jurisdiction, four (4) months after such removal unless
such security interest is perfected in such new jurisdiction within the
expiration of such four (4) month period, and (c) as to any collateral acquired
by such debtor more than four (4) months after such debtor changes its name,
identity or corporate structure so as to make the financing statements related
thereto seriously misleading, to the extent such perfection is achieved by the
filing of financing statements, unless new appropriate financing statements
indicating the new name, identity or corporate structure of such debtor are
properly filed before the expiration of such four (4) months. The applicable
provisions of Section 9-103 of the UCC provide that the laws (including the
conflict of laws rules) of the jurisdiction in which the chief executive office
of the debtor is located govern the perfection and the effect of perfection of a
security interest in accounts, chattel paper (where perfection is effected by
filing a financing statement under the UCC), general intangibles (other than
uncertificated securities) and mobile goods (as such terms are defined in the
UCC) of such debtor.

         We express no opinion as to the effect of Section 9-311 of the UCC on
any provisions of the Loan Documents that limits or prohibits a transfer of the
Borrower's rights in any collateral or makes such a transfer a default.

Ladies and Gentlemen:

                  We have represented the Company, the subsidiaries of the
Company listed on Schedule II hereto (the "Subsidiary Guarantors"), MedCath
Holdings, Inc. (the "Parent"; the Company, the Parent and the Subsidiary
Guarantors being referred to herein collectively as the "Credit Parties") in
connection with the preparation, execution and delivery of the following
documents:

                  A.       the Credit Agreement;

                  B.       the Guaranty (as defined in the Credit Agreement);
                           and

                  C.       the Pledge Agreement (as defined in the Credit

The documents described in the foregoing clauses (A) through (C) are
collectively referred to herein as the "Credit Documents." Other than as

                                                                   July 31, 1998

in the Credit Agreement. This opinion is furnished to you pursuant to Section
3.01 (h)(xi)(B) of the Credit Agreement.

                  In connection with this opinion, we have examined:

                  (A)      the Credit Agreement, signed by each Credit Party
                           party thereto and by the Agent and the Lenders; and

                  (B)      each other Credit Document, signed by each Credit
                           Party party thereto;

We have also examined the originals, or duplicates or certified or conformed
copies, of such records, agreements, instruments and other documents and have
made such other investigations as we have deemed relevant and necessary in
connection with the opinions expressed herein. As to questions of fact material
to this opinion, we have relied upon certificates of public officials and of
officers and representatives of the Credit Parties. In addition, we have
examined, and have relied as to matters of fact upon, the representations made
in the Credit Documents.

                  In rendering the opinions set forth below, we have assumed the
genuineness of all signatures, the legal capacity of natural persons, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as duplicates or certified
or conformed copies, and the authenticity of the originals of such latter
documents.

                  Based upon and subject to the foregoing, and subject to the
qualifications and limitations set forth herein, we are of the opinion that:

                  1.       Each of the Company and the Parent (a) has been duly
         incorporated and is validly existing and in good standing as a
         corporation under the laws of the jurisdiction of its incorporation,
         (b) has the corporate power and authority to execute and deliver each
         of the Credit Documents to which it is a party and to borrow, and
         perform its obligations thereunder and to grant the security interests
         to be granted by it pursuant to the Pledge Agreement and (c) has duly
         authorized, executed and delivered each Credit Document to which it is
         a party.

                  2.       The execution and delivery by each of the Company and
         the Parent of the Credit Documents to which it is a party, the
         Company's borrowings in accordance with the terms of the Credit
         Documents, and performance of its payment obligations thereunder and
         granting of the security interests to be granted by it pursuant to the
         Pledge Agreement (a) will not result in any violation of the
         Certificate of Incorporation or By-Laws of such Credit Party and (b)
         will not breach or result in a default under or result in the creation
         of any lien upon or

                                                                   July 31, 1998

         security interest in such Credit Party's properties pursuant to the
         terms of any material agreement or instrument to which such Credit
         Party is a party.

                  3.       The execution and delivery by each Credit Party of
         the Credit Documents to which it is a party, the Company's borrowings
         in accordance with the terms of the Credit Documents, and performance
         of its payment obligations thereunder, assuming that proceeds of
         borrowings will be used in accordance with the terms of the Credit
         Agreement, will not result in any violation of any Federal or New York
         statute or the Delaware General Corporation Law or any rule or
         regulation issued pursuant to any New York or Federal statute or the
         Delaware General Corporation Law or any order known to us issued by any
         court or governmental agency or body.

                  4.       To our knowledge, there is no action, suit or
         proceeding before or by any court, arbitrator or governmental agency,
         body or official, now pending, to which either of the Company or the
         Parent is a party or to which the business, assets or property of any
         Credit Party is subject and no such action, suit or proceeding is
         threatened to which any Credit Party or the business, assets or
         property of any Credit Party would be subject that in either case
         questions the validity or enforceability of the Credit Documents.

                  5.       No consent, approval, authorization, order, filing,
         registration or qualification of or with any Federal or New York
         governmental agency or body or any Delaware governmental agency or body
         acting pursuant to the Delaware General Corporation Law is required for
         the execution and delivery by any Credit Party of the Credit Documents
         to which it is a party, the borrowings by any Credit Party in
         accordance with the terms of the Credit Documents or the performance by
         the Credit Parties of their respective payment obligations under the
         Credit Documents.

                  6.       Assuming that each of the Credit Documents is a valid
         and legally binding obligation of each of the Lenders parties thereto
         and assuming that (a) execution, delivery and performance by each
         Credit Party other than the Company of the Credit Documents to which it
         is a party do not violate the laws of the jurisdiction in which it is
         organized or any other applicable laws (excepting the laws of the State
         of New York, the General Corporation Law of the State of Delaware and
         the Federal laws of the United States), (b) execution, delivery and
         performance by each Credit Party of the Credit Documents to which it is
         a party do not constitute a breach or violation of any agreement or
         instrument which is binding upon such Credit Party, and (c) no Credit
         Party is an "investment company" within the meaning of and subject to
         regulation under the Investment Company Act of 1940 (except that we do
         not make the assumption in the foregoing clause (b) with respect to the
         agreements and instruments that are the subject of

                                                                   July 31, 1998

         opinion paragraph 2 of this letter, nor do we make the assumption in
         the foregoing clause (c) with respect to the subject matter of opinion
         paragraph 8 below), each Credit Document constitutes the valid and
         legally binding obligation of each Credit Party which is a party
         thereto, enforceable against such Credit Party in accordance with its
         terms.

                  7.       The Pledge Agreement creates in favor of the Agent
         for the benefit of the Lenders a security interest under the New York
         UCC in the securities identified on Schedule I to the Pledge Agreement
         (the "Pledged Securities"). The Agent will have a perfected security
         interest in such Pledged Securities for the benefit of the Lenders
         under the New York UCC upon delivery to the Agent for the benefit of
         the Lenders in the State of New York of the certificates representing
         such Pledged Securities in registered form, indorsed in blank by an
         effective indorsement or accompanied by undated stock powers with
         respect thereto duly indorsed in blank by an effective indorsement.
         Assuming the Agent and each of the Lenders does not have notice of any
         adverse claim to such Pledged Securities, the Agent will acquire the
         security interest in such Pledged Securities for the benefit of the
         Lenders free of any adverse claim.

                  8.       Neither the Company nor the Parent is an "investment
         company" within the meaning of and subject to regulation under the
         Investment Company Act of 1940, as amended.

                  Our opinions in paragraphs 6 and 7 above are subject to (i)
the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, (ii) general equitable principles (whether considered in a proceeding
in equity or at law) and (iii) an implied covenant of good faith and fair
dealing. Our opinions in paragraphs 6 and 7 above also are subject to the
qualification that certain provisions of the Pledge Agreement, in whole or in
part, may not be enforceable, although the inclusion of such provisions does not
render the Pledge Agreement invalid, and the Pledge Agreement and the laws of
the State of New York contain adequate remedial provisions for the practical
realization of the rights and benefits afforded thereby.

                  Our opinion in paragraph 7 is limited to Articles 8 and 9 of
the New York UCC, and therefore does not address (i) collateral of a type not
subject to Article 8 or 9, as the case may be, of the New York UCC, and (ii)
under New York UCC ss. 9-103 what law governs perfection of the security
interests granted in the collateral covered by this opinion letter.

                  We express no opinion with respect to:

                                                                   July 31, 1998

                  (A)      the effect of ss. 9-306(2) of the New York UCC with
         respect to any proceeds of Collateral (as such term is defined in the
         Pledge Agreement) that are not identifiable;

                  (B)      the effect of Section 552 of the Bankruptcy Code (11
         U.S.C. 552) (relating to property acquired by a pledgor after the
         commencement of a case under the United States Bankruptcy Code with
         respect to such pledgor) and Section 506(c) of the Bankruptcy Code (11
         U.S.C. 506(c) (relating to certain costs and expenses of a trustee in
         preserving or disposing of collateral);

                  (C)      the effect of any provision of the Credit Documents
         which is intended to establish any standard other than a standard set
         forth in the New York UCC as the measure of the performance by any
         party thereto of such party's obligations of good faith, diligence,
         reasonableness or care or of the fulfillment of the duties imposed on
         any secured party with respect to the maintenance, disposition or
         redemption of collateral, accounting for surplus proceeds of collateral
         or accepting collateral in discharge of liabilities;

                  (D)      the effect of any provision of the Credit Documents
         which is intended to permit modification thereof only by means of an
         agreement signed in writing by the parties thereto;

                  (E)      the effect of any provision of the Credit Documents
         insofar as it provides that any Person purchasing a participation from
         a Lender or other Person may exercise set-off or similar rights with
         respect to such participation or that any Lender or other Person may
         exercise set-off or similar rights other than in accordance with
         applicable law;

                  (F)      the effect of any provision of the Credit Documents
         imposing penalties or forfeitures;

                  (G)      the enforceability of any provision of any of the
         Credit Documents to the extent that such provision constitutes a waiver
         of illegality as a defense to performance of contract obligations; and

                  (H)      the effect of any provision of the Credit Documents
         relating to indemnification or exculpation in connection with
         violations of any securities laws or relating to indemnification,
         contribution or exculpation in connection with willful, reckless or
         criminal acts or gross negligence of the indemnified or exculpated
         Person or the Person receiving contribution.

                           necessary to authorize action by such Guarantor, and
                           the officers authorized by such Guarantors to act on

                           Documents;

                  h.       The representations and warranties contained in the
                           Guarantors' Documents pertaining to factual matters
                           are true and correct as set forth in this letter;

                           have received from any governmental authority and

                           after delivery, will be properly filed or recorded in
                           the appropriate governmental offices;

                  l.       The result of the application of New York law will
                           not be contrary to a fundamental policy of the law of
                           any other state with which the parties may have
                           contact in connection with the Transactions,
                           including Arizona;

                  m.       No fraud has occurred in connection with the
                           Transactions;

                  n.       Any statute enacted by the legislature, and any rule
                           or regulations issued by an official administrative

                           to render the Guarantors' Documents to which it is a
                           party enforceable; and

                  p.      There is no financial relationship created as a result
                          of the Transaction between an entity providing
                          "designated health care services" (as such term is
                          defined in the so-called "Stark" laws and regulations)
                          and a physician (or an immediate family member of such
                          physician) who makes referrals to such entity.

                  In basing certain of the opinions expressed below on "our
knowledge," the words "our knowledge" signify that, in the course of our
representation of Guarantors as set forth above, and without our investigation
of any records or review of any documents except the Loan Documents, the
Constituent Documents and the Credit Agreement, no information has come to our
attention that has given us conscious awareness that any such opinions are not
accurate or that any of the documents, certificates and information on which we
have relied in expressing any such opinions are not true and complete in all
material respects. The phrase "our knowledge" is limited to the conscious
awareness of the lawyers within our firm who have worked on the Transactions and
does not include constructive knowledge or inquiry knowledge. In rendering

                                       5

the opinions in this letter regarding litigation and similar proceedings, we
have not reviewed any court records or documentation.

         With respect to the assumptions set forth in this letter, we have not
discovered any condition or fact which would make such assumptions unwarranted.
Whenever we have stated in this letter that we have made any assumptions as to
factual matters, such assumption has been made without independent investigation
or verification.

                  The opinions set forth below are subject to the following
qualifications and limitations:

                  (i)      The enforceability of the Guarantors' Documents may
                           be subject to or limited by bankruptcy, insolvency,
                           reorganization, arrangement, moratorium or other
                           similar laws relating to or affecting the rights of
                           creditors generally;

                  (ii)     The enforceability of the Guarantors' Documents is
                           subject to general principles of equity; and

                  (iii)    The enforceability of the Guarantors' Documents is
                           further subject to the qualification that certain
                           waivers, procedures, remedies, choice of law, consent
                           to jurisdiction and other provisions of the
                           Guarantors' Documents may be unenforceable under or
                           limited by the law of the State of Arizona.

                  Based upon, and subject to, the assumptions and the
qualifications set forth in this letter, we are of the opinion that, as of the
date of this letter:

                  (1)      Each Guarantor is a corporation validly existing
                           under the laws of the State of Arizona and each
                           Guarantor has the requisite corporate power to: (i)
                           own its assets; (ii) to carry out its business as
                           such business is currently being conducted; and (iii)
                           to execute and deliver, and to perform its
                           obligations under, the Guarantors' Documents to which
                           it is a party.

                  (2)      The execution and delivery by each Guarantor of the
                           Guarantors' Documents to which it is a party have
                           been duly authorized by all requisite corporate
                           action on the part of such Guarantor and such Loan
                           Documents have been duly executed by such Guarantor.

                  (3)      Neither the execution or delivery of any Guarantor
                           of, nor performance by any Guarantor of its
                           obligations under, the Guarantors' Documents to which
                           it is a party: (a) does or will conflict with,
                           violate or constitute a

                                       6

                           breach of: (i) based solely on the Constituent
                           Documents, the articles of incorporation or bylaws of
                           such Guarantor; (ii) any Applicable Law (as defined
                           below) affecting such Guarantor; (iii) based solely
                           upon our knowledge, any agreement to which such
                           Guarantor is now a party or by which such Guarantor
                           or its property is bound; or (iv) based solely upon
                           our knowledge, any judgment, writ, determination,
                           order, decree or arbitral award to which such
                           Guarantor is a party or by which such Guarantor is
                           bound; (b) requires the prior consent of, notice to,
                           license from or filing with any federal, state or
                           local governmental authority which has not been duly
                           obtained or made on or prior to the date of this
                           letter; (c) based solely upon our knowledge, requires
                           the prior consent of, notice to, license from or
                           filing with any third party which has not been duly
                           obtained or made on or prior to the date of this
                           letter; or (d) based solely upon our knowledge, does
                           or will result in the creation or imposition of any
                           Lien upon or with respect to any of the properties of
                           any Guarantor, except for the Liens created pursuant
                           to the Guarantors' Documents.

                  (4)      Based solely upon our knowledge, there is no material
                           pending or overtly threatened action, suit,
                           investigation or proceeding before or by any court or
                           governmental department, commission, board, bureau,
                           instrumentality, agency or arbitral authority which
                           calls into question the validity or enforceability of
                           the Guarantors' Documents.

                  (5)      The Pledgor Financing Statements are in proper form
                           to perfect the Security Interests (as defined below)
                           covered thereby, but only to the extent that
                           perfection of a security interest in such Collateral
                           (as defined in the Pledge Agreement) is required to
                           or may be effected by filing in Arizona financing
                           statements under the Uniform Commercial Code as in
                           effect in Arizona on the date of this letter (the
                           "UCC"). The opinion in the immediately preceding
                           opinion is based on the following assumptions: (i)
                           attachment of the security interests created in the
                           Collateral by the Pledge Agreement under New York law
                           (the "Security Interests"); (ii) filing and recording
                           in the appropriate governmental offices necessary in
                           order to perfect a security interest in such
                           Collateral; and (iii) the chief executive office
                           (within the meaning of Section 47-9103(C) of the UCC)
                           of each of the Guarantors is in Maricopa County,
                           Arizona. We offer no opinion as to whether, under the
                           circumstances, the filing of the Pledgor Financing
                           Statements is legally sufficient to perfect a
                           security interest in each item of Collateral. We call
                           to your attention that perfection or nonperfection of
                           the Security Interests may be subject to the
                           following qualifications:

                  (a)      in the case of all collateral, Article 9 of the UCC
                           requires the filing of appropriate continuation
                           statements within the period of six (6) months prior
                           to the expiration of six (6) years from the date of
                           the original filings

                                       7
<PAGE>   180

                           (and each sixth year thereafter), in order to
                           maintain the effectiveness of the filings referred to
                           in this paragraph;

                  (b)      in the case of property which becomes collateral
                           after the date of filing, Section 552 of the Federal
                           Bankruptcy Code limits the extent to which property
                           acquired by a debtor after the commencement of a case
                           under the Federal Bankruptcy Code may be subject to a
                           security interest arising from a security agreement
                           entered into by the debtor before the commencement of
                           such case;

                  (c)      under Section 47-9403(A) of the UCC, a financing
                           statement is "filed" if it is presented to the filing
                           officer together with tender of the requisite filing
                           fee or accepted by the filing officer, whether or not
                           such financing statement is ever properly recorded or
                           indexed of record;

                  (d)      the applicable provisions of Section 47-9104 of the
                           UCC provide that Article 9 of the UCC does not apply
                           to collateral of the types described in such Section
                           (including, without limitation, deposit accounts);

                  (e)      acquiring and enforcing a perfected security interest
                           in proceeds of any collateral may be limited under
                           the circumstances described in Section 47-9306 of the
                           UCC;

                  (f)      purchasers of certain collateral may take it free of
                           a perfected security interest under circumstances
                           described in Sections 47-9307 and 47-9308 of the UCC;

                  (g)      a perfected security interest in after-acquired
                           collateral is subject to the rules contained in
                           Section 9-312 of the UCC;

                  (h)      the perfection of the security interests granted by
                           the Pledge Agreement will be terminated: (i) as to
                           collateral consisting of accounts, chattel paper,
                           mobile goods or general intangibles (other than
                           uncertificated securities) (as such terms are defined
                           in the

                                       8

                           UCC), to the extent such perfection is achieved by
                           the filing of financing statements, four (4) months
                           after the chief executive office of the debtor
                           granting such security interests is no longer located
                           in Maricopa County, Arizona, unless new appropriate
                           financing statements are properly filed before the
                           expiration of such four (4) months; (ii) as to any
                           collateral consisting of goods (as such term is
                           defined in the UCC) which are subsequently moved to a
                           differ jurisdiction, four (4) months after such
                           removal unless such security interest is perfected in
                           such new jurisdiction within such four (4) month
                           period; and (iii) as to any collateral acquired by
                           such debtor more than four (4) months after such
                           debtor changes its name, identity or corporate
                           structure so as to make the financing statements
                           related thereto seriously misleading, to the extent
                           such perfection is achieved by the filing of
                           financing statements, unless new appropriate
                           financing statements indicating the new name,
                           identity or corporate structure of such debtor are
                           properly filed before the expiration of such four (4)
                           months. The applicable provisions of Section 47-9103
                           of the UCC provide that the laws (including the
                           conflict of laws rules) of the jurisdiction in which
                           the chief executive office of the debtor is located
                           govern the perfection and the effect of perfection of
                           a security interest in accounts, chattel paper (where
                           perfection is effected by filing a financing
                           statement under the UCC), general intangibles (other
                           than uncertificated securities) and mobile goods (as
                           such terms are defined in the UCC) of such debtor. We
                           express no opinion as to the effect of Section
                           47-9311 of the UCC on any provisions of the
                           Guarantors' Documents that limits or prohibits a
                           transfer of the Borrower's rights in any collateral
                           or makes such a transfer a default and our opinion is
                           limited to collateral in which a security interest
                           may be granted pursuant to Article 9 of the UCC.

                  We are qualified to practice law in the State of Arizona, and
we do not purport to be experts on, or to express any opinion concerning, any
law other than the law of the State of Arizona and applicable federal law
("Applicable Law"). To the extent that the Guarantors' Documents purport to be
governed by the Laws of any jurisdiction other than the State of Arizona, we
have assumed that the laws of such other jurisdiction are identical to the laws
of the State of Arizona. Our engagement did not extend to, and we render no
opinion about, any federal or state tax, securities, environmental, public
health or labor laws or rules, zoning matters

                                       9

or applicable building codes or ordinances or the effects of any such matters,
if any, on the opinions expressed in this letter.

                  The opinions expressed in this letter are based upon the law
in effect on the date of this letter, and we assume no obligation to revise or
supplement this opinion should such law be changed by legislative action,
judicial decision or otherwise. Furthermore, each opinion expressed in this
letter deals with the specific legal issues it explicitly addresses.
Accordingly, each expressed opinion concerning a particular legal issue does not
address any other matters and does not include any implied opinion.

         This opinion incorporates by reference, and is to be interpreted in
accordance with, the Report of the State Bar of Arizona Corporate, Banking and
Business Law, Section Subcommittee on Rendering Legal Opinions, dated February
1, 1989.

                  This opinion is furnished to Lender solely for the benefit of
the addressees of this letter, any successor and assignee of any addressee,
including successive assignees, and any person who shall acquire a participation
interest in any Lender (collectively, the "Reliance Parties"), and only with
respect to the Transactions. Accordingly, it may not be relied upon by any other
person or entity without, in each instance, our prior written consent. Without
limiting the generality of the foregoing, the opinion shall not be quoted or
otherwise included, summarized or referred to in any publication or documents,
in whole or in part, for any purposes whatsoever, or furnished to any Person
other than a Reliance Party (or a Person considering whether to become a
Reliance Party), except as may be required of any Reliance Party by applicable
law or regulation or in accordance with any auditing or oversight function or
request of regulatory agencies to which a Reliance Party is subject.

                          FORM OF SOLVENCY CERTIFICATE

         [Name of Loan Party], a [State of Incorporation] corporation (the
"[Company] [Borrower]"), hereby certifies that the person executing this
Solvency Certificate, [Officer's Name] is a [Title] of the [Company][Borrower]
and that such officer is duly authorized to execute this Solvency Certificate,
which is hereby delivered on behalf of the [Company] [Borrower] pursuant to
Section 3.01(h)(x) of the Credit Agreement dated as of July 31, 1998 (said
Agreement, as it may hereafter be amended, supplemented or otherwise modified
from time to time, being the "Credit Agreement"; the terms defined therein and
not otherwise defined herein being used herein as therein defined), among
[MedCath Intermediate Holdings, Inc., a Delaware corporation (the
"Borrower")][the Borrower], the Lender Parties thereto, NationsBank, N.A., as
Administrative Agent and NationsBanc Montgomery Securities LLC, as arranger and
syndication agent for the Lender Parties.

         The [Company][Borrower] further certifies that such officer is
generally familiar with the properties, businesses and assets of the
[Company][Borrower] and its Subsidiaries and has carefully reviewed the Loan
Documents, the Related Documents and the contents of this Solvency Certificate
and in connection herewith, has reviewed such other documentation and
information and has made such investigation and inquiries as the
[Company][Borrower] and such officer deem necessary and prudent therefor. The
[Company] [Borrower] further certifies that the financial information and
assumptions that underlie and form the basis for the representations made in
this Solvency Certificate were reasonable when made and were made in good faith
and continue to be reasonable as of the date hereof.

         [On the date hereof, the Borrower intends to borrow up to $100,000,000
under the Credit Agreement. The Lender Parties have agreed to lend from time to
time to the Borrower and issue Letters of Credit for the account of the Borrower
on the terms and conditions set forth in the Credit Agreement to provide working
capital for the Borrower and its Subsidiaries.]

         To secure, among other things, the payment of the Obligations of the
Borrower under the Loan Documents, the [Company][Borrower] is [guaranteeing the
obligations of the Borrower under the Loan Documents] [and pledging the capital
stock of [the Borrower][certain of its Subsidiaries] pursuant to the Collateral
Documents].

<PAGE>   185

         The [Company][Borrower] understands that the Administrative Agent, the
Lender Parties and the Issuing Bank are relying on the truth and accuracy of
this Solvency Certificate in connection with the transactions contemplated the
Loan Documents.

         The [Company] [Borrower] hereby further certifies that:

         1.       The [Company][Borrower] has reviewed MedCath Incorporated's
("MedCath") projected balance sheet and the related income statement and
statement of cash flows and MedCath's projected Consolidated balance sheet and
MedCath's and its Subsidiaries' related income statement and statement of cash
flows in each case prepared by its management, including projected Consolidated
financial statements and forecasts relating to income statements of MedCath on
an annual basis for the fiscal years of MedCath ending on or about September 30,
1998 through [September 30, 2005] (collectively, the "Projected Financial
Statements"), which were prepared on the basis of the estimates and assumptions
stated therein, a copy of which Projected Financial Statements] were prepared in
good faith and represent the Borrower's reasonable estimate of its future
financial performance and are reasonable in light of the business conditions
existing on the date hereof. On the date hereof, after giving effect to the
consummation of the Merger and the other transactions contemplated by the Credit
Agreement, the other Loan Documents and the Related Documents, the fair value of
the property of the [Company][Borrower] is greater than the total amount of
liabilities (including contingent, subordinated, absolute, fixed, matured or
unmatured and liquidated or unliquidated liabilities) of the
[Company][Borrower].

         2.       On the date hereof, after giving effect to the consummation of
the Merger and the other transactions contemplated by the Credit Agreement, the
other Loan Documents and the Related Documents, the present fair saleable value
of the assets of the [Company] [Borrower] exceeds the amount that will be
required to pay the probable liabilities of the [Company][Borrower] on its debts
as they become absolute and matured.

         3.       On the date hereof, after giving effect to the consummation of
the Merger and the other transactions contemplated by the Credit Agreement, the
other Loan Documents and the Related Documents, the [Company][Borrower] is not
engaged in business or in a transaction, and is not about to engage in business
or in a transaction, for which its property would constitute unreasonably small
capital giving due consideration to the prevailing practice in the industry in
which it is engaged).

         4.       The [Company][Borrower] does not intend or believe that it
will incur debts and liabilities that will be beyond its ability to pay as such
debts or liabilities mature.

                                       2
<PAGE>   186

         5.       The [Company][Borrower] does not intend, in consummating the
transactions contemplated by the Credit Agreement, the other Loan Documents and
the Related Documents, to hinder, delay or defraud either present or future
creditors or any other Person to which the [Company][Borrower] is or will become
on or after the date hereof, indebted.

         6.       In reaching the conclusions set forth in this Solvency
Certificate, the [Company] [Borrower] has considered, among other things:

                  (a)      the cash and other current assets of MedCath
         reflected in the March 31, 1998 unaudited Consolidated balance sheet of
         Medcath and its Consolidated Subsidiaries;

                  (b)      all contingent liabilities of the
         [Company][Borrower], including without limitation, any claims arising
         out of, pending or, to the best knowledge of the undersigned,
         threatened litigation against the [Company][Borrower], and in so doing,
         the [Company][Borrower] has computed the amount of each such contingent
         liability as the amount that, in light of all the facts and
         circumstances existing on the date hereof, represents the amount that
         can reasonably be expected to become an actual or matured liability;

                  (c)      all obligations and liabilities of the
         [Company][Borrower], whether matured or unmatured, liquidated or
         unliquidated, disputed or undisputed, secured or unsecured,
         subordinated, absolute, fixed or contingent, including, among other
         things, claims arising out of, pending, or to the best knowledge of the
         undersigned, threatened litigation against the [Company][Borrower];

                  [(d)     historical and anticipated growth in the sales volume
         of [the Company] [MedCath] and in the income stream generated by [the
         Company][MedCath] as reflected in, among other things, the cash flow
         statement delivered to as part of the Projected Financial Statements;]

                  (e)      the customary terms of the trade payables of [the
         Company] [MedCath];

                  (f)      the amount of the credit extended by and to customers
         of [the Company] [MedCath];

                  (g)      the level of capital customarily maintained by [the
         Company][MedCath] and other entities engaged in the same or similar
         business as the business of [the Company][MedCath]; and

                  (h)      the Projected Financial Statements.

         Delivery of an executed counterpart of a signature page to this
Solvency Certificate by telecopier shall be effective as delivery of a manually
executed counterpart of this Solvency Certificate.

         IN WITNESS WHEREOF, the chief financial officer has executed this
Solvency Certificate in his corporate capacity and on behalf of the
[Company][MedCath] this 31st day of July, 1998.

                                       4

Loan Documents (including, without limitation, (A) all due diligence, collateral
review, syndication, transportation, computer, duplication, appraisal, audit,
insurance, consultant, search, filing and recording fees and expenses and (B)
the reasonable fees and expenses of counsel for the Administrative Agent with
respect thereto, with respect to advising the Administrative Agent as to its
rights and responsibilities, or the perfection, protection or preservation of
rights or interests, under the Loan Documents, with respect to negotiations with
any Loan Party or with other creditors of any Loan Party or any of its
Subsidiaries arising out of any Default or any events or circumstances that may
give rise to a Default and with respect to presenting claims in or otherwise
participating in or monitoring any bankruptcy, insolvency or other similar
proceeding involving creditors' rights generally and any proceeding ancillary
thereto) and (ii) all costs and expenses of the Administrative Agent and the
Lender Parties in connection with the enforcement of the Loan Documents, whether
in any action, suit or litigation, any bankruptcy, insolvency or other similar
proceeding affecting creditors' rights generally (including, without limitation,
the reasonable fees and expenses of counsel for the Administrative Agent and
each Lender Party with respect thereto).

                  (b) The Borrower agrees to indemnify and hold harmless
the Administrative Agent, each Lender Party and each of their Affiliates and
their officers, directors, employees, agents and advisors (each, an "Indemnified
Party") from and against any and all claims, damages, losses, liabilities and
expenses (including, without limitation, reasonable fees and expenses of
counsel) that may be incurred by or asserted or awarded against any Indemnified
Party, in each case arising out of or in connection with or by reason of
(including, without limitation, in connection with any investigation, litigation
or proceeding or preparation of a defense in connection therewith) (i) the
Facilities, the actual or proposed use of the proceeds of the Advances or the
Letters of Credit, the Loan Documents or any of the transactions contemplated
thereby, or (ii) the actual or alleged presence of Hazardous Materials on any
property of any Loan Party or any of its Subsidiaries or any Environmental
Action relating in any way to any Loan Party or any of its Subsidiaries, except
to the extent, in each case, such claim, damage, loss, liability or expense (i)
results from such Indemnified Party's gross negligence or willful misconduct or
(ii) arises from disputes among the Agents and/or the Lender Parties. In the
case of an investigation, litigation or other proceeding to which the indemnity
in this Section 8.04(b) applies, such indemnity shall be effective whether or
not such investigation, litigation or proceeding is brought by any Loan Party,
its directors, shareholders or creditors or an Indemnified Party or any
Indemnified Party is otherwise a party thereto and whether or not the
transactions contemplated hereby are consummated. It is understood that this
subsection (b) does not preclude the Borrower from making any claim for breach
of this Agreement against any Lender.

                  (c) If any payment of principal of, or Conversion of, any
Eurodollar Rate Advance is made by the Borrower to or for the account of a
Lender Party other than on the last day of the Interest Period for such Advance,
as a result of a payment or Conversion pursuant to Section 2.09, acceleration of
the maturity of the Working Capital Notes pursuant to Section 6.01 or for any
other reason, the Borrower shall, upon demand by such Lender Party

                                       87
<PAGE>   189

(with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender Party any amounts required
to compensate such Lender Party for any additional losses, costs or expenses
that it may reasonably incur as a result of such payment, including, without
limitation, any loss, cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender Party to fund or
maintain such Advance.

                  (d) If any Loan Party fails to pay when due any costs,
expenses or other amounts payable by it under any Loan Document, including,
without limitation, fees and expenses of counsel and indemnities, such amount
may be paid on behalf of such Loan Party by the Administrative Agent or any
Lender Party, in its sole discretion.

                  (e) Without prejudice to the survival of any other
agreement of any Loan Party hereunder or under any other Loan Document, the
agreements and obligations of the Borrower contained in Sections 2.10 and 2.12
and this Section 8.04 shall survive the payment in full of principal, interest
and all other amounts payable hereunder and under any of the other Loan
Documents.

                  SECTION 8.05. Right of Set-off. Upon (a) the occurrence and
during the continuance of any Event of Default and (b) the making of the request
or the granting of the consent specified by Section 6.01 to authorize the
Administrative Agent to declare the Working Capital Notes due and payable
pursuant to the provisions of Section 6.01, each Lender Party and each of its
respective Affiliates is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and otherwise apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender Party or such
Affiliate to or for the credit or the account of the Borrower against any and
all of the Obligations of the Borrower now or hereafter existing under this
Agreement and the Working Capital Note or Working Capital Notes (if any) held by
such Lender Party, irrespective of whether such Lender Party shall have made any
demand under this Agreement or such Working Capital Note or Working Capital
Notes and although such obligations may be unmatured. Each Lender Party agrees
promptly to notify the Borrower after any such set-off and application;
provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Lender Party and
its respective Affiliates under this Section are in addition to other rights and
remedies (including, without limitation, other rights of set-off) that such
Lender Party and its respective Affiliates may have.

                  SECTION 8.06. Binding Effect. This Agreement shall become
effective when it shall have been executed by the Borrower and the
Administrative Agent and when the Administrative Agent shall have been notified
by each Initial Lender and the Initial Issuing Bank that such Initial Lender and
the Initial Issuing Bank has executed it and thereafter shall be binding upon
and inure to the benefit of the Borrower, the Administrative Agent and each
Lender Party and their respective successors and assigns, except that the
Borrower shall not have the right to assign its rights hereunder or any interest
herein without the prior written consent of the Lender Parties.

                  SECTION 8.07. Assignments and Participations. (a) Each Lender
may, with the consent of the Administrative Agent, and, so long as no Event of
Default has occurred and is continuing, with the consent of the Borrower (in
each case, such consent not to be unreasonably withheld), assign to one or more
Eligible Assignees all or a portion of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Commitment or
Commitments, the Advances owing to it and the Working Capital Note or Working
Capital Notes held by it); provided, however, that no consent by the Borrower or
the Administrative Agent shall be required for an assignment to any Person who
is an Affiliate of such Lender; provided further that (i) each such assignment
shall be of a uniform, and not a varying, percentage of all rights and
obligations under and in respect of the Facilities, (ii) except in the case of
an assignment to a Person that, immediately prior to such assignment, was a
Lender or an assignment of all of a Lender's rights and obligations under this
Agreement, the amount of the Commitment of the assigning Lender being assigned
pursuant to each such assignment (determined as of the date of the Assignment
and Acceptance with respect to such assignment) shall in no event be less than
$5,000,000 (or integral multiples of $1,000,000 in excess thereof), (iii) each
such assignment shall be to an Eligible Assignee, and (vi) the parties to each
such assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment and Acceptance, together
with any Working Capital Note or Working Capital Notes subject to such
assignment and, other than in the case of an assignment to an Affiliate of such
Lender, a processing and recordation fee of $3,500.

                  (b) Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in such Assignment and
Acceptance, (x) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, have the rights and obligations of a Lender
or Issuing Bank, as the case may be, hereunder and (y) the Lender or Issuing
Bank assignor thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's or Issuing Bank's rights and obligations under
this Agreement, such Lender or Issuing Bank shall cease to be a party hereto).

                  (c) By executing and delivering an Assignment and
Acceptance, the Lender Party assignor thereunder and the assignee thereunder
confirm to and agree with each other and the other parties hereto as follows:
(i) other than as provided in such Assignment and Acceptance, such assigning
Lender Party makes no representation or warranty and assumes no responsibility
with respect to any statements, warranties or representations made in or in
connection with this Agreement or any other Loan Document or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to
be created under or in connection with, this Agreement or any other Loan
Document or any other instrument or document furnished

                                       89
<PAGE>   191

pursuant hereto or thereto; (ii) such assigning Lender Party makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of the Borrower or any other Loan Party or the performance
or observance by any Loan Party of any of its obligations under any Loan
Document or any other instrument or document furnished pursuant thereto; (iii)
such assignee confirms that it has received a copy of this Agreement, together
with copies of the financial statements referred to in Section 4.01 and such
other documents and information as it has deemed appropriate to make its own
credit analysis and decision to enter into such Assignment and Acceptance; (iv)
such assignee will, independently and without reliance upon the Administrative
Agent, such assigning Lender Party or any other Lender Party and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such
assignee appoints and authorizes the Administrative Agent to take such action as
agent on its behalf and to exercise such powers and discretion under the Loan
Documents as are delegated to the Administrative Agent by the terms hereof,
together with such powers and discretion as are reasonably incidental thereto;
and (vii) such assignee agrees that it will perform in accordance with their
terms all of the obligations which by the terms of this Agreement are required
to be performed by it as a Lender or Issuing Bank, as the case may be.

                  (d) The Administrative Agent, acting for this purpose
(but only for this purpose) as the agent of the Borrower, shall maintain at its
address referred to in Section 8.02 a copy of each Assignment and Acceptance
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Lender Parties and the Commitment under each Facility of,
and principal amount of the Advances owing under each Facility to, each Lender
Party from time to time (the "Register"). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Administrative Agent and the Lender Parties shall treat each
Person whose name is recorded in the Register as a Lender Party hereunder for
all purposes of this Agreement. The Register shall be available for inspection
by the Borrower or any Lender Party at any reasonable time and from time to time
upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender Party and an assignee, together with any Working
Capital Note or Working Capital Notes subject to such assignment, the
Administrative Agent shall, if such Assignment and Acceptance has been completed
and is in substantially the form of Exhibit C hereto, (i) accept such Assignment
and Acceptance, (ii) record the information contained therein in the Register
and (iii) give prompt notice thereof to the Borrower. In the case of any
assignment by a Lender, within five Business Days after its receipt of such
notice, the Borrower, at its own expense, shall execute and deliver to the
Administrative Agent in exchange for the surrendered Working Capital Note or
Working Capital Notes a new Working Capital Note to the order of such Eligible
Assignee in an amount equal to the Commitment assumed by it under a Facility
pursuant to such Assignment and Acceptance and, if the assigning Lender has
retained a Commitment hereunder under such Facility, a new Working Capital Note
to the

                                       90
<PAGE>   192

order of the assigning Lender in an amount equal to the Commitment retained by
it hereunder. Such new Working Capital Note or Working Capital Notes shall be in
an aggregate principal amount equal to the aggregate principal amount of such
surrendered Working Capital Note or Working Capital Notes, shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of Exhibit A.

                  (f) The Issuing Bank may, with the consent of the
Administrative Agent, and, so long as no Event of Default shall have occurred
and be continuing, with the consent of the Borrower (such consent not to be
unreasonably withheld), assign to an Eligible Assignee all of its rights and
obligations under the undrawn portion of its Letter of Credit Commitment at any
time; provided, however, that (i) each such assignment shall be to an Eligible
Assignee and (ii) the parties to each such assignment shall execute and deliver
to the Administrative Agent, for its acceptance and recording in the Register,
an Assignment and Acceptance, together with a processing and recordation fee of
$3,500.

                  (g) Each Lender Party may sell participations to one or
more Persons (other than any Loan Party or any of its Affiliates) in or to all
or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Commitments, the Advances owing to
it and the Working Capital Note or Working Capital Notes (if any) held by it);
provided, however, that (i) such Lender Party's rights and obligations under
this Agreement (including, without limitation, its Commitments) shall remain
unchanged, (ii) such Lender Party shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) such Lender Party
shall remain the holder of any such Working Capital Note for all purposes of
this Agreement, (iv) the Borrower, the Administrative Agent and the other Lender
Parties shall continue to deal solely and directly with such Lender Party in
connection with such Lender Party's rights and obligations under this Agreement,
(v) no participant under any such participation shall have any right to approve
any amendment or waiver of any provision of any Loan Document, or any consent to
any departure by any Loan Party therefrom, except to the extent that such
amendment, waiver or consent would reduce the principal of, or interest (other
than increased interest following Default pursuant to Section 2.07(b) on, the
Working Capital Notes or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation, postpone any Termination Date,
or date fixed for payment of interest on, the Working Capital Notes or any fees
or other amounts payable hereunder, in each case to the extent subject to such
participation, or release all or substantially all of the Collateral, and (vi)
the Borrower shall not be subject to any increased liability to any Lender Party
pursuant to this Agreement by virtue of such participation.

                  (h) Any Lender Party may, in connection with any
assignment or participation or proposed assignment or participation pursuant to
this Section 8.07, disclose to the assignee or participant or proposed assignee
or participant, any information relating to the Borrower furnished to such
Lender Party by or on behalf of the Borrower; provided, however, that, prior to
any such disclosure, the assignee or participant or proposed assignee or

                                       91
<PAGE>   193

participant shall agree to preserve the confidentiality of any Confidential
Information received by it from such Lender Party.

                  (i) Notwithstanding any other provision set forth in this
Agreement, any Lender Party may at any time create a security interest in all or
any portion of its rights under this Agreement (including, without limitation,
the Advances owing to it and the Working Capital Note or Working Capital Notes
held by it) in favor of any Federal Reserve Bank in accordance with Regulation A
of the Board of Governors of the Federal Reserve System.

                  SECTION 8.08. Replacements of Lenders Under Certain
Circumstances. The Borrower shall be permitted to replace any Lender that (a)
requests reimbursement for amounts owing pursuant to Section 2.10 or 2.12, (b)
is affected in the manner described in Section 2.10(d) and as a result thereof
any of the actions described in such Section is required to be taken or (c)
becomes a Defaulting Lender, with a replacement bank or other financial
institution, provided that (i) such replacement does not conflict with any
Requirement of Law, (ii) no Event of Default shall have occurred and be
continuing at the time of such replacement, (iii) the Borrower shall repay (or
the replacement bank or institution shall purchase, at par) all Advances and
other amounts (other than any disputed amounts), pursuant to Section 2.10 or
2.12, as the case may be) owing to such replaced Lender prior to the date of
replacement, (iv) the replacement bank or institution, if not already a Lender,
and the terms and conditions of such replacement, shall be reasonably
satisfactory to the Administrative Agent, (v) the replaced Lender shall be
obligated to make such replacement in accordance with the provisions of Section
8.07 (provided that the Borrower shall be obligated to pay the registration and
processing fee referred to therein) and (vi) any such replacement shall not be
deemed to be a waiver of any rights that the Borrower, the Administrative Agent
or any other Lender Party shall have against the replaced Lender.

                  SECTION 8.09. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

                  SECTION 8.10. No Liability of the Issuing Bank. The Borrower
assumes all risks of the acts or omissions of any beneficiary or transferee of
any Letter of Credit with respect to its use of such Letter of Credit. Neither
the Issuing Bank nor any of its officers or directors shall be liable or
responsible for: (a) the use that may be made of any Letter of Credit or any
acts or omissions of any beneficiary or transferee in connection therewith; (b)
the validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; (c) payment by the Issuing Bank
against presentation of documents that do not comply with the terms of a Letter
of Credit, including failure of any documents to bear any reference

or adequate reference to the Letter of Credit; or (d) any other circumstances
whatsoever in making or failing to make payment under any Letter of Credit,
except that the Borrower shall have a claim against the Issuing Bank, and the
Issuing Bank shall be liable to the Borrower, to the extent of any direct, but
not consequential, damages suffered by the Borrower that the Borrower proves
were caused by (i) the Issuing Bank's willful misconduct or gross negligence in
determining whether documents presented under any Letter of Credit comply with
the terms of the Letter of Credit or (ii) the Issuing Bank's willful failure to
make lawful payment under a Letter of Credit after the presentation to it of a
draft and certificates strictly complying with the terms and conditions of the
Letter of Credit. In furtherance and not in limitation of the foregoing, the
Issuing Bank may accept documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary.

                  SECTION 8.11. Confidentiality. The Administrative Agent and
each Lender shall hold all non-public information furnished by or on behalf of
the Borrower in connection with such Lender's evaluation of whether to become a
Lender hereunder or obtained by such Lender or the Administrative Agent pursuant
to the requirements of this Agreement ("Confidential Information"), in
accordance with its customary procedure for handling confidential information of
this nature and (in the case of a Lender that is a bank) in accordance with safe
and sound banking practices. Neither the Administrative Agent nor any Lender
Party shall disclose any Confidential Information to any Person without the
consent of the Borrower, other than (a) to the Administrative Agent's or such
Lender Party's Affiliates and their officers, directors, employees, agents and
advisors and to actual or prospective Eligible Assignees and participants, and
then only on a confidential basis, (b) as required by any law, rule or
regulation or judicial process and (c) as requested or required by any state,
federal or foreign authority or examiner regulating such Lender Party or the
Administrative Agent.

                  SECTION 8.12. Jurisdiction, Etc. (a) Each of the parties
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or any of the other Loan Documents to which it is a
party, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in any such
New York State court or, to the extent permitted by law, in such federal court.
The Borrower irrevocably consents to the service of any and all process in any
such action or proceeding by the mailing of copies of such process by registered
or certified mail (or any substantially similar form of mail), postage prepaid,
to the Borrower at its address specified in Section 8.02 and agrees that nothing
herein shall affect the right to effect service of process in any other manner
permitted by law or shall limit the right to sue in any other jurisdiction. Each
of the parties hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions

                                       93

by suit on the judgment or in any other manner provided by law. Nothing in this
Agreement shall affect any right that any party may otherwise have to bring any
action or proceeding relating to this Agreement or any of the other Loan
Documents in the courts of any jurisdiction.

                  (b) Each of the parties hereto irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection that it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
any of the other Loan Documents to which it is a party in any New York State or
federal court. Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

                  SECTION 8.13. Governing Law. This Agreement and the Working
Capital Notes shall be governed by, and construed in accordance with, the laws
of the State of New York, United States.

                  SECTION 8.14. Waiver of Jury Trial. Each of the Borrower, the
Administrative Agent and the Lender Parties irrevocably waives all right to
trial by jury in any action, proceeding or counterclaim (whether based on
contract, tort or otherwise) arising out of or relating to any of the Loan
Documents, the Advances or the actions of the Administrative Agent or any Lender
Party in the negotiation, administration, performance or enforcement thereof.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be executed by their respective officers thereunto duly authorized,
as of the date first above written.
