                                   The Loans

         2.01 Revolving Credit Facility

         (a)  Commitment.  Subject to the terms and conditions of this
Agreement, each Lender severally agrees to make Advances to the Borrower, from
time to time from the Closing Date until but not including the Revolving Credit
Termination Date on a pro rata basis as to the total borrowing requested by the
Borrower on any day determined by its Applicable Commitment Percentage up to
but not exceeding the Revolving Credit Commitment of such Lender, provided,
however, that the Lenders will not be required and shall have no obligation to
make any Advance (i) so long as a Default or an Event of Default has occurred
and is continuing or (ii) if the Agent has accelerated the maturity of the
Notes as a result of an Event of Default; provided further, however, that
immediately after giving effect to each Advance, the principal amount of
outstanding Loans plus the amount of all Outstanding Letters of Credit and
Swing Line Outstandings shall not exceed the Total Revolving Credit Commitment.
Within such limits, the Borrower may borrow, repay and reborrow hereunder, on a
Business Day in the case of a Base Rate Loan and on a Euro Business Day in the
case of a Eurodollar Rate Loan, from the Closing Date until, but (as to
borrowings and reborrowings) not including, the Revolving Credit Termination
Date; provided, however, that (x) no Eurodollar Rate Loan shall be made which
has an Interest Period that extends beyond the Revolving Credit Termination
Date and (y) each Eurodollar Rate Loan may, subject to the provisions of
Section 2.08, be repaid only on the last day of the Interest Period with
respect thereto.

         (b)  Amounts.  The aggregate unpaid principal amount of the Loans,
Outstanding Letters of Credit and Swing Line Outstandings shall not exceed at
any time, an amount equal to the Total Revolving Credit Commitment.  Each Loan
hereunder and each conversion under Section 2.08 shall be in an amount of at
least $500,000, and, if greater than $500,000, an integral multiple of
$100,000.

         (c)  Advances.  (i)  An Authorized Representative shall give the Agent
(1) at least three (3) Euro Business Days' irrevocable telefacsimile or
telephonic notice of each Eurodollar Rate Loan (whether representing an
additional borrowing hereunder or the conversion of borrowing hereunder from
Base Rate Loans to Eurodollar Rate Loans) prior to 11:00 A.M., Charlotte, North
Carolina time; and (2) irrevocable telefacsimile or telephonic notice of each
Base Rate Loan representing an additional borrowing hereunder prior to 11:00
A.M. Charlotte, North Carolina time on the day of such proposed Base Rate Loan.
Each such Borrowing Notice, which shall be effective upon receipt by the Agent,
shall specify the amount of the borrowing, the type (Base or Eurodollar) of
Loan, the date of borrowing, if a Eurodollar Rate Loan, the Interest





                                       23
<PAGE>   29

Period to be used in the computation of interest and the manner of
disbursement.  The Authorized Representative shall provide the Agent written
confirmation of each such telephonic notice on the same day by telefacsimile
transmission in the form attached hereto as Exhibit D or E, as applicable, with
appropriate insertions but failure to provide such confirmation shall not
affect the validity of such telephonic notice.  Notice of receipt of such
Borrowing Notice shall be provided by the Agent to each Lender by telephone or
telefacsimile with reasonable promptness, but not later than 1:00 P.M.,
Charlotte, North Carolina time on the same day as Agent's receipt of such
notice.  The Agent shall provide each Lender written confirmation of such
telephonic confirmation by telefacsimile transmission but failure to provide
such notice shall not affect the validity of such telephonic notice.

         (ii)  Not later than 2:00 P.M., Charlotte, North Carolina time on the
date specified for each borrowing under this Section 2.01, each Lender shall,
pursuant to the terms and subject to the conditions of this Agreement, make the
amount of the Loan or Loans to be made by it on such day available to the
Agent, by depositing or transferring the proceeds thereof in immediately
available funds at the Principal Office.  The amount so received by the Agent
shall, subject to the terms and conditions of this Agreement, be made available
to the Borrower by delivery of the proceeds thereof  as shall be directed in
the applicable Borrowing Notice by the Authorized Representative.

         (iii)  Notwithstanding the foregoing, if a drawing is made under any
Letter of Credit prior to the Revolving Credit Termination Date, the drawing
shall be paid by the Agent without the requirement of notice from the Borrower
from immediately available funds which shall be advanced by the Lenders under
the Revolving Credit Facility.  If a drawing is presented under any Letter of
Credit in accordance with the terms thereof and if Borrower shall not
immediately reimburse NationsBank for the amount of such draw or payment then
notice of such drawing or payment shall be provided promptly by NationsBank to
the Agent and the Agent shall provide notice to each Lender by telephone or
telefacsimile.  If notice to the Lenders of a drawing under any Letter of
Credit is given by the Agent at or before 12:00 noon Charlotte, North Carolina
time on any Business Day, each Lender shall, pursuant to the conditions of this
Agreement, make a Base Rate Loan in the amount of such Lender's Applicable
Commitment Percentage of such drawing or payment and shall pay such amount to
the Agent for the account of NationsBank at the Principal Office in Dollars and
in immediately available funds before 2:30 P.M. Charlotte, North Carolina time
on the same Business Day.  If notice to the Lenders of a drawing under a Letter
of Credit is given by the Agent after 12:00 noon Charlotte, North Carolina time
on any Business Day, each Lender shall, pursuant to the terms and subject to
the conditions of this Agreement, make a Base Rate Loan in the amount of such
Lender's Applicable Commitment Percentage of such drawing or payment and shall
pay such amount to the Agent for the





                                       24
<PAGE>   30

account of NationsBank at the Principal Office in Dollars and in immediately
available funds before 12:00 noon Charlotte, North Carolina time on the next
following Business Day.  Such Base Rate Loan shall continue unless and until
the Borrower converts such Base Rate Loan in accordance with the terms of
Section 2.08 hereof.

         2.02 Payment of Interest.  (a) The Borrower shall pay interest to the
Agent for the account of each Lender on the outstanding and unpaid principal
amount of each Loan made by such Lender for the period commencing on the date of
such Loan until such Loan shall be due at the then applicable Base Rate for Base
Rate Loans or applicable Eurodollar Rate for Eurodollar Rate Loans, as
designated by the Authorized Representative pursuant to Section 2.01 hereof or
as otherwise provided herein; provided, however, that if any amount shall not be
paid when due (at maturity, by acceleration or otherwise), all amounts
outstanding hereunder shall bear interest thereafter (i) in the case of a
Eurodollar Rate Loan, until the end of the Interest Period with respect to such
Eurodollar Rate Loan, at a rate of two percent (2%) above such Eurodollar Rate
and (ii) thereafter, and with respect to Base Rate Loans, at a rate of interest
per annum which shall be four percent (4%) above the Base Rate or the maximum
rate permitted by applicable law, whichever is lower, from the date such amount
was due and payable until the date such amount is paid in full.

         (b)  Interest on each Loan shall be computed on the basis of a year of
360 days and calculated for the actual number of days elapsed.  Interest on
each Loan shall be paid (a) quarterly in arrears on the last Business Day of
each March, June, September and December, commencing June 30, 1996, on each
Base Rate Loan, (b) on the last day of the applicable Interest Period for each
Eurodollar Rate Loan, or at the end of each three month period, whichever is
earlier, and (c) upon payment in full of the principal amount of such Loan and
termination of this Agreement.

         2.03 Payment of Principal.  (a) The principal amount of each Loan shall
be due and payable to the Agent for the benefit of each Lender in full on the
Revolving Credit Termination Date.  The duration of the initial Interest Period
for each Loan that is a Eurodollar Rate Loan shall be as specified in the
initial Borrowing Notice.  The Borrower shall have the option to elect the
duration of subsequent Interest Periods and to convert the Loans in accordance
with Section 2.08 hereof.  If the Agent does not receive a notice of election of
duration of an Interest Period or to convert by the time prescribed by Section
2.08 hereof, the Borrower shall be deemed to have elected to convert such Loan
to (or continue such Loan as) a Base Rate Loan until the Borrower notifies the
Agent in accordance with Section 2.08.

         (b)  Each payment of principal (including any prepayment) and payment
of interest shall be made to the Agent at the Principal Office, for the account
of each Lender's applicable Lending Office, in Dollars and in immediately
available funds before 12:30 P.M.





                                       25

Charlotte, North Carolina time on the date such payment is due.  The Agent may,
but shall not be obligated to, debit the amount of any such payment which is
not made by such time to any ordinary deposit account, if any, of the Borrower
with the Agent.  The Borrower shall give the Agent prior telephonic or
telefacsimile notice of any payment of principal, such notice to be given by
not later than 11:00 a.m. Charlotte, North Carolina time, on the date of such
payment.

         (c) The Agent shall deem any payment by or on behalf of the Borrower
hereunder that is not made both (a) in Dollars and in immediately available
funds and (b) prior to 12:30 P.M. Charlotte, North Carolina time to be a non-
conforming payment. Any such payment shall not be deemed to be received by the
Agent until the time such funds become available funds. Any non-conforming
payment may constitute or become a Default or Event of Default. The Agent shall
give prompt telephonic notice to the Authorized Representative and each of the
Lenders (confirmed in writing) if any payment is non-conforming. Interest shall
continue to accrue on any principal as to which a non-conforming payment is made
until such funds become available funds (but in no event less than the period
from the date of such payment to the next succeeding Business Day) at a rate of
interest per annum which shall be two percent (2%) above the Base Rate or the
maximum rate permitted by applicable law, whichever is lower, from the date such
amount was due and payable until the date such amount is paid in full.

         (d) In the event that any payment hereunder or under the Notes becomes
due and payable on a day other than a Business Day, then such due date shall be
extended to the next succeeding Business Day; provided that interest shall
continue to accrue during the period of any such extension.

         2.04  Notes.  (a) Loans (other than Swing Line Loans) made by each
Lender shall be evidenced by, and be repayable with interest in accordance with
the terms of, the promissory notes payable to the order of such Lender in the
respective amounts of its Applicable Commitment Percentage of the Total
Revolving Credit Commitment, which Notes shall be dated the Closing Date or such
later date pursuant to an Assignment and Acceptance and shall be duly completed,
executed and delivered by the Borrower.

         (b)  Swing Line Loans made by NationsBank shall be evidenced by and
repayable with interest, in accordance with the terms of, the promissory note
payable to the order of NationsBank in the principal amount of $10,000,000.

         2.05  Pro Rata Payments.  Except as otherwise provided herein, (a) each
payment on account of the principal of and interest on the Loans and the fees
described in Section 2.09 hereof shall be made to the Agent for the account of
the Lenders pro rata based on their Applicable Commitment Percentages, (b) all
payments to be made by the Borrower for the account of each of the Lenders on
account of





                                       26
<PAGE>   32

principal, interest and fees, shall be made without set-off or counterclaim,
and (c) the Agent will promptly distribute payments received to the Lenders.

         2.06  Reductions.  The Borrower shall, by notice from an Authorized
Representative, have the right from time to time (but not more frequently than
once during each fiscal quarter), upon not less than five (5) Business Days
written notice to the Agent to reduce the Total Revolving Credit Commitment. The
Agent shall give each Lender, within one (1) Business Day, telephonic notice
(confirmed in writing) of such reduction.  Each such reduction shall be in the
aggregate amount of $5,000,000 or such greater amount which is in an integral
multiple of $1,000,000, and shall permanently reduce the Total Revolving Credit
Commitment of the Lenders pro rata.  No such reduction shall result in the
payment of any Eurodollar Rate Loan other than on the last day of the Interest
Period of such Loan unless such prepayment is accompanied by amounts due, if
any, under Section 4.04.  Each reduction of the Total Revolving Credit
Commitment shall be accompanied by payment of the Notes to the extent that the
sum of the Revolving Credit Debit Balance, the Outstanding Letters of Credit and
Swing Line Outstandings exceeds the Total Revolving Credit Commitment, after
giving effect to such reduction, together with accrued and unpaid interest on
the amounts prepaid.

         2.07 Increase and Decrease in Amounts. The amount of the Total
Revolving Credit Commitment which shall be available to the Borrower shall be
reduced by the aggregate amount of all Outstanding Letters of Credit and Swing
Line Outstandings.

         2.08 Conversions and Elections of Subsequent Interest Periods. Provided
that no Default or Event of Default shall have occurred and be continuing and
subject to the limitations set forth below and in Sections 4.01(b), 4.02 and
4.03 hereof, the Borrower may:

         (a) upon notice to the Agent on or before 10:30 A.M. Charlotte, North
Carolina time on any Business Day convert all or a part of Eurodollar Rate Loans
to Base Rate Loans on the last day of the Interest Period for such Eurodollar
Rate Loans;

         (b) on three (3) Euro Business Days' notice to the Agent on or before
10:30 A.M. Charlotte, North Carolina time:

                  (i) elect a subsequent Interest Period for all or a portion of
         Eurodollar Rate Loans to begin on the last day of the current Interest
         Period for such Eurodollar Rate Loans;

                  (ii) convert Base Rate Loans to Eurodollar Rate Loans on any
         date.

         Notice of any such elections or conversions shall be in the form of
Exhibit E attached hereto and shall specify the effective





                                       27
<PAGE>   33

date of such election or conversion and the Interest Period to be applicable to
the Loan as continued or converted. Each election and conversion pursuant to
this Section 2.08 shall be subject to the limitations on Eurodollar Rate Loans
set forth in the definition of "Interest Period" herein and in Sections 2.01,
2.02 and Article IV hereof. All such continuations or conversions of Loans shall
be effected pro rata based on the Applicable Commitment Percentages of the
Lenders.

         2.09 Fee. For the period beginning on the date of satisfaction of the
conditions set forth in Section 5.02 and ending on the Revolving Credit
Termination Date (or such earlier date on which the Revolving Credit Facility
has terminated), the Borrower agrees to pay to the Agent, for the pro rata
benefit of the Lenders based on their Applicable Commitment Percentages, the
Unused Fee. Such payments of fees provided for in this subsection (b) shall be
due in arrears on the last Business Day of each March, June, September and
December beginning June 30, 1996 to and on the Revolving Credit Termination Date
(or such earlier date on which the Revolving Credit Facility has terminated).
Notwithstanding the foregoing, so long as any Lender fails to make available any
portion of its Revolving Credit Commitment when requested, such Lender shall not
be entitled to receive payment of its pro rata share of such fee until such
Lender shall make available such portion. Such fee shall be calculated on the
basis of a year of 360 days for the actual number of days elapsed.

         2.10 Deficiency Advances. No Lender shall be responsible for any
default of any other Lender in respect to such other Lender's obligation to make
any Loan hereunder nor shall the Revolving Credit Commitment of any Lender
hereunder be increased as a result of such default of any other Lender. Without
limiting the generality of the foregoing, in the event any Lender shall fail to
advance funds to the Borrower as herein provided, the Agent may in its
discretion, but shall not be obligated to, advance under the Note in its favor
as a Lender all or any portion of such amount or amounts (each, a "deficiency
advance") and shall thereafter be entitled to payments of principal of and
interest on such deficiency advance in the same manner and at the same interest
rate or rates to which such other Lender would have been entitled had it made
such advance under its Note; provided that, upon payment to the Agent from such
other Lender of the entire outstanding amount of each such deficiency advance,
together with accrued and unpaid interest thereon, from the most recent date or
dates interest was paid to the Agent by the Borrower on each Loan comprising the
deficiency advance at the interest rate per annum for overnight borrowing by the
Agent from the Federal Reserve Bank, then such payment shall be credited against
the applicable Note of the Agent in full payment of such deficiency advance and
the Borrower shall be deemed to have borrowed the amount of such deficiency
advance from such other Lender as of the most recent date or dates, as the





                                       28
<PAGE>   34

case may be, upon which any payments of interest were made by the Borrower
thereon.

         2.11 Adjustments by Agent. Notwithstanding the construction of "pro
rata" to mean based on the Applicable Percentage Commitments and any provisions
contained herein for the advancement of funds or distribution of payments on a
pro rata basis, the Agent may, in its discretion, but shall not be obligated to,
adjust downward or upward (but not in excess of any applicable Revolving Credit
Commitment) the principal amount of any Loan to be made by any Lender to the
nearest amount which is evenly divisible by $100, and make appropriate related
adjustment in the distribution of payments of principal and interest on the
Loans.

         2.12 Use of Proceeds. The proceeds of the Loans made pursuant to the
Revolving Credit Facility hereunder shall be used by the Borrower (i) to make
loans and investments permitted under Section 8.10(v), and (ii) for general
corporate purposes, including the acquisition of health care related properties
by lease or purchase.

         2.13 Extension of Revolving Credit Termination Date. At the request of
the Borrower the Lenders may, in their sole discretion, elect to extend the
Revolving Credit Termination Date then in effect for two additional periods of
one year each. The Borrower shall notify the Lenders of its request for such an
extension by delivering to the Agent and the Lenders notice of such request
signed by an Authorized Representative not more than ninety (90) days nor less
than sixty (60) days prior to the first or second anniversary of the Closing
Date. If the Lenders shall elect to so extend, the Agent shall notify the
Borrower in writing within thirty (30) days of its receipt of such request for
extension of the decision of the Lenders of whether to extend the Revolving
Credit Termination Date. Failure by the Agent to give such notice shall
constitute refusal by the Lenders to extend the Revolving Credit Termination
Date.

         2.l4. Swing Line. (a) Notwithstanding any other provision of this
Agreement to the contrary, in order to administer the Revolving Credit Facility
in an efficient manner and to minimize the transfer of funds between the Agent
and the Lenders, NationsBank shall make available Swing Line Loans to the
Borrower prior to the Revolving Credit Termination Date. NationsBank shall not
make any Swing Line Loan pursuant hereto (i) if to the actual knowledge of
NationsBank the Borrower is not in compliance with all the conditions to the
making of Loans set forth in this Agreement, (ii) if after giving effect to such
Swing Line Loan, the Swing Line Outstandings exceed $10,000,000 or (iii) if
after giving effect to such Swing Line Loan, the sum of the Swing Line
Outstandings, Revolving Credit Outstandings and Letter of Credit Outstandings
exceeds the Total Revolving Credit Commitment. Swing Line Loans shall be limited
to Base Rate Loans. The Company may borrow, repay and reborrow under this
Section 2.l4. Unless notified to the





                                       29
<PAGE>   35

contrary by NationsBank, borrowings under the Swing Line shall be made in the
minimum amount of $100,000 or, if greater, in amounts which are integral
multiples of $10,000, upon written request by telefacsimile transmission,
effective upon receipt, by an Authorized Representative of the Borrower made to
NationsBank not later than 12:30 P.M. on the Business Day of the requested
borrowing.  Each such Borrowing Notice shall specify the amount of the
borrowing and the date of borrowing, and shall be in the form of Exhibit D-2,
with appropriate insertions.   Unless notified to the contrary by NationsBank,
each repayment of a Swing Line Loan shall be in an amount which is an integral
multiple of $10,000 or the aggregate amount of all Swing Line Outstandings.  If
the Borrower instructs NationsBank to debit any demand deposit account of the
Borrower in the amount of any payment with respect to a Swing Line Loan, or
NationsBank otherwise receives repayment, after 12:30 P.M. on a Business Day,
such payment shall be deemed received on the next Business Day.

         (b) Swing Line Loans shall bear interest at the Base Rate or such other
rate as may be agreed to by the Borrower and NationsBank, the interest payable
on Swing Line Loans is solely for the account of NationsBank, and all accrued
and unpaid interest on Swing Line Loans shall be payable on the dates and in the
manner provided in Section 2.02 with respect to interest on Base Rate Loans. The
Swing Line Outstandings shall be evidenced by the Note delivered to NationsBank
pursuant to Section 2.04(b).

         (c) Upon the making of a Swing Line Loan, each Lender shall be deemed
to have purchased from NationsBank a Participation therein in an amount equal to
that Lender's Applicable Commitment Percentage of such Swing Line Loan. Upon
demand made by NationsBank, each Lender shall, according to its Applicable
Commitment Percentage of such Swing Line Loan, promptly provide to NationsBank
its purchase price therefor in an amount equal to its Participation therein. Any
Advance made by a Lender pursuant to demand of NationsBank of the purchase price
of its Participation shall be deemed a Base Rate Loan under Section 2.01 until
the Borrower converts such Base Rate Loan in accordance with the terms of
Section 2.08. The obligation of each Lender to so provide its purchase price to
NationsBank shall be absolute and unconditional and shall not be affected by the
occurrence of an Event of Default or any other occurrence or event.

         The Borrower, at its option and subject to the terms hereof, may
request an Advance pursuant to Section 2.01 in an amount sufficient to repay
Swing Line Outstandings on any date and the Agent shall provide from the
proceeds of such Advance to NationsBank the amount necessary to repay such
Swing Line Outstandings (which NationsBank shall then apply to such repayment)
and credit any balance of the Advance in immediately available funds in the
manner directed by the Borrower pursuant to Section 2.01(c)(ii).  The proceeds
of such Advances shall be paid to NationsBank for application to the Swing Line
Outstandings and the





                                       30
<PAGE>   36

Lenders shall then be deemed to have made Loans in the amount of such Advances.
The Swing Line shall continue in effect until the Revolving Credit Termination
Date, at which time all Swing Line Outstandings and accrued interest thereon
shall be due and payable in full.

                                  ARTICLE III

                               Letters of Credit

         3.01 Letters of Credit. NationsBank agrees, subject to the terms and
conditions of this Agreement, upon request of Borrower to issue from time to
time for the account of Borrower Letters of Credit upon delivery to NationsBank
of an Application and Agreement for Letter of Credit in form and content
acceptable to NationsBank; provided, that the Outstanding Letters of Credit
shall not exceed the Total Letter of Credit Commitment. No Letter of Credit
shall be issued by NationsBank with an (i) expiry date greater than one year
from the date of issuance of such Letter of Credit and (ii) an expiry date or
payment date occurring subsequent to the fifth Business Day preceding the
Revolving Credit Termination Date. NationsBank shall not be required to issue
any Letter of Credit if the Outstanding Letters of Credit and Swing Line
Outstandings when added to the face amount of any requested Letter of Credit and
the Revolving Credit Debit Balance exceeds the Total Revolving Credit
Commitment.

         3.02 Reimbursement.

                 (a) The Borrower hereby unconditionally agrees immediately to
pay to NationsBank on demand at the Principal Office all amounts required to pay
all drafts drawn or purporting to be drawn under the Letters of Credit and all
reasonable expenses incurred by NationsBank in connection with the Letters of
Credit and in any event and without demand to place in possession of NationsBank
(which shall include Advances under the Revolving Credit Facility if permitted
by Section 2.01(c) hereof and Swing Line Loans if permitted under Section 2.14)
sufficient funds to pay all debts and liabilities arising under any Letter of
Credit. The Borrower's obligations to pay NationsBank under this Section 3.02,
and NationsBank's right to receive the same, shall be absolute and unconditional
and shall not be affected by any circumstance whatsoever. NationsBank agrees to
give the Borrower prompt notice of any request for a draw under a Letter of
Credit. NationsBank may charge any account the Borrower may have with it for any
and all amounts NationsBank pays under a Letter of Credit, plus charges and
reasonable expenses as from time to time agreed to by NationsBank and the
Borrower; provided that to the extent permitted by Section 2.01(c)(iii) and
Section 2.14, amounts shall be paid pursuant to Advances under the Revolving
Credit Facility or, if the Borrower shall elect, by Swing Line Loans. The
Borrower agrees that NationsBank may, in its sole discretion, accept or pay, as
complying with the terms of any Letter of Credit, any drafts or other documents
otherwise in order which may be signed or issued by an administrator, executor,
trustee in bankruptcy, debtor in possession, assignee for the benefit of
creditors, liquidator, receiver, attorney in fact or other legal representative
of a party who is authorized under such Letter of Credit to draw or issue any
drafts or other documents. The Borrower agrees to pay NationsBank





                                       32
<PAGE>   38

interest on any amounts not paid when due hereunder at the Base Rate plus two
percent (2%), or the maximum rate permitted by applicable law, if lower.

                  (b) In accordance with the provisions of Section 2.01(c)
hereof, NationsBank shall notify the Agent (and shall also notify the Borrower)
of any drawing under any Letter of Credit as promptly as practicable following
the receipt by NationsBank of such drawing.

                  (c) Each Lender (other than NationsBank) shall automatically
acquire on the date of issuance thereof, a Participation in the liability of
NationsBank in respect of each Letter of Credit in an amount equal to such
Lender's Applicable Commitment Percentage of such liability, and to the extent
that the Borrower is obligated to pay NationsBank under Section 3.02(a), each
Lender (other than NationsBank) thereby shall absolutely, unconditionally and
irrevocably assume, and shall be unconditionally obligated to pay to NationsBank
as hereinafter described, its Applicable Commitment Percentage of the liability
of NationsBank under such Letter of Credit. Prior to the Revolving Credit
Termination Date, each Lender (including NationsBank in its capacity as a
Lender) shall, subject to the terms and conditions of Article II, make a Base
Rate Loan to the Borrower by paying to the Agent for the account of NationsBank
at the Principal Office in Dollars and in immediately available funds, an amount
equal to its Applicable Commitment Percentage of any drawing under a Letter of
Credit, all as described and pursuant to Section 2.01(c). With respect to
drawings under any of the Letters of Credit, each Lender, upon receipt from the
Agent of notice of a drawing in the manner described in Section 2.01(c), shall
promptly pay to the Agent for the account of NationsBank, prior to the
applicable time set forth in Section 2.01(c), its Applicable Commitment
Percentage of such drawing. Simultaneously with the making of each such payment
by a Lender to NationsBank, such Lender shall, automatically and without any
further action on the part of NationsBank or such Lender, acquire a
Participation in an amount equal to such payment (excluding the portion thereof
constituting interest) in the related Reimbursement Obligation of the Borrower.
The Reimbursement Obligations of the Borrower shall be immediately due and
payable whether by Advances made in accordance with Section 2.01(c), Swing Line
Loans in accordance with Section 2.14, or otherwise. Each Lender's obligation to
make payment to the Agent for the account of NationsBank pursuant to this
Section 3.02(c), and the right of NationsBank to receive the same, shall be
absolute and unconditional, shall not be affected by any circumstance whatsoever
and shall be made without any offset, abatement, withholding or reduction
whatsoever. If any Lender is obligated to pay but does not pay amounts to the
Agent for the account of NationsBank in full upon such request as required by
this Section 3.02(c), such Lender shall, on demand, pay to the Agent for the
account of NationsBank interest on the unpaid amount for each day during the
period commencing on the date of notice





                                       33
<PAGE>   39

given to such Lender pursuant to Section 2.01(c) until such Lender pays such
amount to the Agent for the account of NationsBank in full at the interest rate
per annum for overnight borrowing by NationsBank from the Federal Reserve Bank.

                  (d) Promptly following the end of each calendar quarter,
NationsBank shall deliver to the Agent a notice describing the aggregate undrawn
amount of all Letters of Credit at the end of such quarter. Upon the request of
any Lender from time to time, NationsBank shall deliver to the Agent, and the
Agent shall deliver to such Lender, any other information reasonably requested
by such Lender with respect to each Outstanding Letter of Credit.

                  (e) The issuance by NationsBank of each Letter of Credit
shall, in addition to the conditions precedent set forth in Section 5.01 hereof,
be subject to the conditions that such Letter of Credit be in such form and
contain such terms as shall be reasonably satisfactory to NationsBank consistent
with the then current practices and procedures of NationsBank with respect to
similar letters of credit, and the Borrower shall have executed and delivered
such other instruments and agreements relating to such Letters of Credit as
NationsBank shall have reasonably requested consistent with such practices and
procedures. All Letters of Credit shall be issued pursuant to and subject to the
Uniform Customs and Practice for Documentary Credits, 1993 revision,
International Chamber of Commerce Publication No. 500 and all subsequent
amendments and revisions thereto.

                  (f) Without duplication of Section 10.07 hereof, the Borrower
hereby agrees to indemnify and hold harmless NationsBank, each other Lender and
the Agent from and against any and all claims and damages, losses, liabilities,
reasonable costs and expenses which NationsBank, such other Lender or the Agent
may incur (or which may be claimed against NationsBank, such other Lender or the
Agent) by any Person by reason of or in connection with the issuance or transfer
of or payment or failure to pay under any Letter of Credit; provided that the
Borrower shall not be required to indemnify NationsBank, any other Lender or the
Agent for any claims, damages, losses, liabilities, costs or expenses to the
extent, but only to the extent, (i) caused by the willful misconduct or gross
negligence of the party to be indemnified or (ii) caused by the failure of
NationsBank to pay under any Letter of Credit after the presentation to it of a
request strictly complying with the terms and conditions of such Letter of
Credit, unless such payment is prohibited by any law, regulation, court order or
decree. The indemnification and hold harmless provisions of this Section 3.02(f)
shall survive repayment of the Obligations, occurrence of the Revolving Credit
Termination Date and expiration or termination of this Agreement.

                  (g) Without limiting Borrower's rights as set forth in Section
3.02(f) above, the obligation of the Borrower to immediately reimburse Agent for
drawings made under Letters of





                                       34
<PAGE>   40

Credit shall be absolute, unconditional and irrevocable, and shall be performed
strictly in accordance with the terms of this Agreement and such Letters of
Credit and the related applications for any Letter of Credit, under all
circumstances whatsoever, including, without limitation, the following
circumstances:

                  (i) any lack of validity or enforceability of the Letter of
Credit, the obligation supported by the Letter of Credit or any other agreement
or instrument relating thereto (collectively, the "Related Documents");

                  (ii) any amendment or waiver of or any consent to or departure
from all or any of the Related Documents;

                  (iii) the existence of any claim, setoff, defense (other than
the defense of payment in accordance with the terms of this Agreement) or other
rights which the Borrower may have at any time against any beneficiary or any
transferee of a Letter of Credit (or any persons or entities for whom any such
beneficiary or any such transferee may be acting), Agent, Lenders or any other
person or entity, whether in connection with the Loan Documents, the Related
Documents or any unrelated transaction;

                  (iv) any breach of contract or other dispute between the
Borrower and any beneficiary or any transferee of a Letter of Credit (or any
persons or entities for whom such beneficiary or any such transferee may be
acting), Agent, Lenders or any other Person;

                  (v) any draft, statement or any other document presented under
the 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 whatsoever;

                  (vi) any delay, extension of time, renewal, compromise or
other indulgence or modification granted or agreed to by Agent, with or without
notice to or approval by the Borrower in respect of any of Borrower's
Obligations under this Agreement; or

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

provided, however, that nothing contained herein shall be deemed to release
NationsBank or any other Lender of any liability for actual loss arising as a
result of its gross negligence or willful misconduct or out of the wrongful
dishonor by NationsBank of a proper demand for payment made under and strictly
complying with the terms of any Letter of Credit.

         3.03 Letter of Credit Fee. The Borrower agrees to pay to the Agent, for
the pro rata benefit of the Lenders based on their Applicable Commitment
Percentages, a fee on the aggregate amount available to be drawn on each
Outstanding Letter of Credit at a rate per annum equal to the Applicable Margin
in effect from time





                                       35
<PAGE>   41

to time.  Such payment of fees provided for in this Section 3.03 shall be due
with respect to each Letter of Credit quarterly in arrears, on the last day of
each March, June, September and December.  Such fee shall be calculated on the
basis of a year of 360 days for the actual number of days elapsed.  In
addition, the Borrower shall pay to the Agent a Letter of Credit fronting fee
of one-eighth of one percent (1/8%) per annum of the face amount of each Letter
of Credit, such fee to be paid in arrears on the last day of each March, June,
September and December, the first such payment to be due on the first such date
occurring after there is more than one Lender.

         3.04 Administrative Fees and Reserves. The Borrower shall pay to
NationsBank such administrative fee and other fees, if any, in connection with
the Letters of Credit in such amounts and at such times as NationsBank and the
Borrower shall agree from time to time.

                                   ARTICLE IV

                        Yield Protection and Illegality

         4.01 Additional Costs. (a) The Borrower shall promptly pay to the Agent
for the account of a Lender from time to time, without duplication, such amounts
as such Lender may reasonably determine to be necessary to compensate it for any
costs incurred by such Lender which it determines are attributable to its making
or maintaining any Loan or its obligation to make any Loans, or the issuance or
maintenance by NationsBank of or any other Lender's Participation in any Letter
of Credit issued or Swing Line Loan extended hereunder, or any reduction in any
amount receivable by such Lender under this Agreement, the Notes or the Letters
of Credit in respect of any of such Loans or such obligation or the Letters of
Credit, including reductions in the rate of return on a Lender's capital (such
increases in costs and reductions in amounts receivable and returns being herein
called "Additional Costs"), resulting from any Regulatory Change which: (i)
changes the basis of taxation of any amounts payable to such Lender under this
Agreement or the Notes in respect of any of such Loans or Letters of Credit
(other than taxes imposed on or measured by the income, revenues or assets); or
(ii) imposes or modifies any reserve, special deposit, or similar requirements
relating to any extensions of credit or other assets of, or any deposits with or
other liabilities of, such Lender (other than any such reserve, deposit or
requirement reflected in the Prime Rate, the Federal Funds Effective Rate or the
Eurodollar Rate, in each case computed in accordance with the respective
definitions of such terms set forth in Section 1.01 hereof); or (iii) has or
would have the effect of reducing the rate of return on capital of any such
Lender to a level below that which the Lender could have achieved but for such
Regulatory Change (taking into consideration such Lender's policies with respect
to capital adequacy); or (iv) imposes any other condition adversely affecting
the Agent or the Lenders under this Agreement, the Notes or the issuance or
maintenance of, or any Lender's Participation in, the Letters of Credit or Swing
Line Loans (or any of such extensions of credit or liabilities). Each Lender
will notify the Authorized Representative and the Agent of any event occurring
after the Closing Date which would entitle it to compensation pursuant to this
Section 4.01(a) as promptly as practicable after it obtains knowledge thereof
and determines to request such compensation.

         (b) Without limiting the effect of the foregoing provisions of this
Section 4.01, in the event that, by reason of any Regulatory Change, any Lender
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
the Lender which includes deposits by reference to which the interest rate on
Eurodollar Rate Loans is determined as provided in this Agreement or a category
of extensions of credit or other assets of any Lender which includes Eurodollar
Rate Loans or (ii) becomes subject to





                                       37
<PAGE>   43

restrictions on the amount of such a category of liabilities or assets which it
may hold, then, if the Lender so elects by notice to the other Lenders, the
obligation hereunder of such Lender to make, and to convert Base Rate Loans
into, Eurodollar Rate Loans that are the subject of such restrictions shall be
suspended until the date such Regulatory Change ceases to be in effect and the
Borrower shall, on the last day(s) of the then current Interest Period(s) for
outstanding Eurodollar Rate Loans convert such Eurodollar Rate Loans into Base
Rate Loans; provided, however, that the suspension of such obligation and the
conversion of any Eurodollar Rate Loans into Base Rate Loans shall apply only
to any Lender who is affected by such restrictions and who has provided such
notice to the other Lenders, and the obligation of the other Lenders to make,
and to convert Base Rate Loans into, Eurodollar Rate Loans shall not be
affected by such restrictions.  In the event that the obligation of some, but
not all of the Lenders to make, or to convert Base Rate Loans into, Eurodollar
Rate Loans is suspended, then any request by the Borrower during the pendency
of such suspension for a Eurodollar Rate Loan shall be deemed a request for
such Eurodollar Rate Loan from the Lender(s) not subject to such suspension and
for a Base Rate Loan from the Lender(s) who are subject to such suspension, in
each case in the respective amounts based on the Lenders' respective Revolving
Credit Commitments.

         (c) Determinations by any Lender for purposes of this Section 4.01 of
the effect of any Regulatory Change on its costs of making or maintaining, or
being committed to make, Loans or by NationsBank as issuer of any Letter of
Credit of the effect of any Regulatory Change on its costs in connection with
the issuance or maintenance of, or any other Lender's Participation in, any
Letter of Credit issued or Swing Line Loans extended hereunder, or on amounts
receivable by any Lender in respect of Loans or Letters of Credit, and of the
additional amounts required to compensate the Lender in respect of any
Additional Costs, shall be conclusive absent manifest error, provided that such
determinations are made on a reasonable basis taking into account such Lender's
reasonable policies as to the allocation of capital, costs and other items. The
Lender requesting such compensation shall furnish to the Authorized
Representative and the Agent within one hundred and eighty (180) days of the
incurrence of any Additional Costs for which compensation is sought an
explanation of the Regulatory Change and calculations, in reasonable detail,
setting forth such Lender's determination of any such Additional Costs.

         4.02 Suspension of Loans. Anything herein to the contrary
notwithstanding, if, on or prior to the determination of any interest rate for
any Eurodollar Rate Loan for any Interest Period, the Agent determines (which
determination made on a reasonable basis shall be conclusive absent manifest
error) that:

                  (a) quotations of interest rates for the relevant deposits
         referred to in the definition of "Eurodollar Rate" in





                                       38
<PAGE>   44

         Section 1.01 hereof are not being provided in the relevant amounts or
         for the relevant maturities for purposes of determining the rate of
         interest for such Eurodollar Rate Loan as provided in this Agreement;
         or

                  (b) the relevant rates of interest referred to in the
         definition of "Base Rate" in Section 1.01 hereof upon the basis of
         which the Eurodollar Rate for such Interest Period is to be determined
         do not adequately reflect the cost to the Lenders of making or
         maintaining such Eurodollar Rate Loan for such Interest Period or such
         Eurodollar Rate Loan (which determination shall be made on a reasonable
         basis by the Agent, and the Person making such determination shall
         furnish the Authorized Representative evidence of the facts leading to
         such determination);

then the Agent shall give the Authorized Representative prompt notice thereof,
and so long as such condition remains in effect, the Lenders shall be under no
obligation to make Eurodollar Rate Loans that are subject to such condition, or
to convert Loans into Eurodollar Rate Loans, and the Borrower shall on the last
day(s) of the then current Interest Period(s) for outstanding Eurodollar Rate
Loans, as applicable, convert such Eurodollar Rate Loans into a Eurodollar Rate
Loan if such Eurodollar Rate Loan is not subject to the same or similar
condition, or Base Rate Loans, if available hereunder.  The Agent shall give
the Authorized Representative notice describing in reasonable detail any event
or condition described in this Section 4.02 promptly following the
determination by the Agent that the availability of Eurodollar Rate Loans is,
or is to be, suspended as a result thereof.

         4.03 Illegality. Notwithstanding any other provision of this Agreement,
in the event that it becomes unlawful for any Lender to honor its obligation to
make or maintain Eurodollar Rate Loans hereunder, then such Lender shall
promptly notify the Borrower thereof (with a copy to the Agent) and such
Lender's obligation to make or continue Eurodollar Rate Loans, or convert Base
Rate Loans into Eurodollar Rate Loans, shall be suspended until such time as
such Lender may again make and maintain Eurodollar Rate Loans, and such Lender's
outstanding Eurodollar Rate Loans shall be converted into Base Rate Loans in
accordance with Section 2.08 hereof.

         4.04 Compensation. The Borrower shall promptly pay to each Lender, upon
the request of such Lender, such amount or amounts as shall be sufficient (in
the reasonable determination of Lender) to compensate it for any loss, cost or
expense incurred by it as a result of:

                  (a) any payment, prepayment or conversion of a Eurodollar Rate
         Loan on a date other than the last day of the Interest Period for such
         Eurodollar Rate Loan, including without limitation any conversion
         required pursuant to Section 4.03; or





                                       39
<PAGE>   45


                  (b) any failure by the Borrower to borrow a Eurodollar Rate
         Loan on the date for such borrowing specified in the relevant Borrowing
         Notice under Article II hereof;

such compensation to include, without limitation, an amount equal to the
excess, if any, of (i) the amount of interest which would have accrued on the
principal amount so paid, prepaid or converted or not borrowed for the period
from the date of such payment, prepayment or conversion or failure to borrow or
convert to the last day of the then current Interest Period for such Loan (or,
in the case of a failure to borrow or convert, the Interest Period for such
Loan which would have commenced on the date scheduled for such borrowing or
conversion) at the applicable rate of interest for such Eurodollar Rate Loan
provided for herein over (ii) the Interbank Offered Rate (as reasonably
determined by the Agent) for Dollar deposits of amounts comparable to such
principal amount and maturities comparable to such period.  A determination of
a Lender as to the amounts payable pursuant to this Section 4.04 shall be
conclusive, provided that such determinations are made on a reasonable basis.
The Lender requesting compensation under this Section 4.04 shall furnish to the
Authorized Representative and the Agent calculations in reasonable detail
setting forth such Lender's determination of the amount of such compensation.

         4.05 Alternate Loan and Lender. (a) In the event any Lender suspends
the making of any Eurodollar Rate Loan pursuant to this Article IV (herein a
"Restricted Lender"), the Restricted Lender's Commitment Percentage of any
Eurodollar Rate Loan shall bear interest at either the Base Rate or the
Eurodollar Rate for which the suspension does not apply, as selected by
Borrower, until the Restricted Lender once again makes available the applicable
Eurodollar Rate Loan. Notwithstanding the provisions of Section 2.02(b),
interest shall be payable to the Restricted Lender at the time and manner as
paid to those Lenders making available Eurodollar Rate Loans.

         (b) In the event any Lender shall continue to be a Restricted Lender
for more than three consecutive months, such Restricted Lender hereby agrees
that upon the request of the Borrower, upon the Borrower causing to be delivered
to the Agent (i) a substitute lender acceptable to the Agent, (ii) an Assignment
and Acceptance Agreement executed by such substitute lender pursuant to Section
11.01(a), and (iii) immediately available funds in an amount sufficient to pay
all amounts owed hereunder to such Restricted Lender, it shall execute the
Assignment and Acceptance Agreement referred to above and surrender its Note to
the Borrower upon receipt of payment of amounts owed to its under this
Agreement.

         4.06 Taxes. All payments by the Borrower of principal of, and interest
on, the Loans and all other amounts payable hereunder shall be made free and
clear of and without deduction for any present or future excise, stamp or other
taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other
charges





                                       40
<PAGE>   46

of any nature whatsoever imposed by any taxing authority, but excluding (i)
franchise taxes, (ii) any taxes (other than withholding taxes) that would not be
imposed but for a connection between a Lender or the Agent and the jurisdiction
imposing such taxes (other than a connection arising solely by virtue of the
activities of such Lender or the Agent pursuant to or in respect of this
Agreement or any other Loan Document), (iii) any withholding taxes payable with
respect to payments hereunder or under any other Loan Document under laws
(including, without limitation, any statute, treaty, ruling, determination or
regulation) in effect on the Closing Date, (iv) any taxes imposed on or measured
by any Lender's assets, net income, receipts or branch profits and (v) any taxes
arising after the Closing Date solely as a result of or attributable to Lender
changing its designated lending office after the date such Lender becomes a
party hereto (such non-excluded items being collectively called "Taxes"). In the
event that any withholding or deduction from any payment to be made by the
Borrower hereunder is required in respect of any Taxes pursuant to any
applicable law, rule or regulation, then the Borrower will

                  (a) pay directly to the relevant authority the full amount
         required to be so withheld or deducted;

                  (b) promptly forward to the Agent an official receipt or other
         documentation satisfactory to the Agent evidencing such payment to such
         authority; and

                  (c) pay to the Agent for the account of the Lender such
         additional amount or amounts as is necessary to ensure that the net
         amount actually received by each Lender will equal the full amount such
         Lender would have received had no such withholding or deduction been
         required.

         Prior to the date that any Lender or participant organized under the
laws of a jurisdiction outside the United States becomes a party hereto, such
Person shall deliver to the Borrower and the Agent such certificates, documents
or other evidence, as required by the Code or Treasury Regulations issued
pursuant thereto, properly completed, currently effective and duly executed by
such Lender or participant establishing that such payment is (i) not subject to
United States Federal backup withholding tax and (ii) not subject to United
States Federal withholding tax under the Code because such payment is either
effectively connected with the conduct by such Lender or participant of a trade
or business in the United States or totally exempt from United States Federal
withholding tax by reason of the application of the provisions of a treaty to
which the United States is a party or such Lender is otherwise exempt.

         If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Agent, for the account of the
respective Lender, the required receipts or other required documentary
evidence, the Borrower shall indemnify





                                       41

                  requisite power and authority to own its properties and assets
                  and to carry on its business as now being conducted and as
                  contemplated in the Loan Documents, and (y) is qualified to do
                  business in every jurisdiction in which failure so to qualify

                           (iii) the Borrower has the power and authority to

                           (iv) when executed and delivered, each of the Loan
                  Documents to which it is a party will be the legal, valid and
                  binding obligation or agreement, as the case may be, of the
                  Borrower and each Subsidiary, enforceable against the Borrower
                  and each Subsidiary in accordance with its terms, subject to
                  the effect of any applicable bankruptcy, moratorium,
                  insolvency, reorganization or other similar law affecting the
                  enforceability of creditors' rights generally and to the
                  effect of general principles of equity which may limit the
                  availability of equitable remedies (whether in a proceeding at
                  law or in equity);

                  (b) Loan Documents. The execution, delivery and performance by

                  breach of or constitute an event of default, or an event
                  which, with notice or lapse of time, or both, would constitute
                  an event of default, under any indenture, agreement or other
                  instrument to which Borrower or any Subsidiary is a party, or

                  (c) Solvency. Borrower is Solvent after giving effect to the
         transactions contemplated by this Agreement and the other Loan
         Documents.

                  (d) Subsidiaries and Stockholders. Borrower has no
         Subsidiaries other than those Persons listed as Subsidiaries in

         Subsidiary; the outstanding shares or other equity interests of each
         such Subsidiary have been duly authorized and validly issued and are

         Principles applied on a Consistent Basis, except that the interim
         financial statements have been prepared in accordance with the
         accounting principles applied, and in the manner used, for the
         preparation of interim unaudited consolidated financial statements of
         the Borrower and its Subsidiaries for previous interim fiscal periods
         and present the consolidated financial condition of the Borrower and
         its Subsidiaries as of their respective dates and the results of
         operations of the Borrower and its Subsidiaries for the periods then
         ended.  Except as disclosed therein, neither the Borrower nor any
         Subsidiaries has, as of the date hereof, any known and material direct
         liability;

                  (ii) since March 31, 1996, there has been no material adverse
         change in the condition, financial or otherwise, of the Borrower and

         obligations, commitments or other liability contingent or otherwise
         which remain outstanding or unsatisfied;

                  (g) Title to Properties. The Borrower and its Subsidiaries

         restrictions or Liens of any kind, except for Liens permitted under

                  (h) Taxes. The Borrower and its Subsidiaries have filed or
         caused to be filed all federal, state and local tax returns which are
         required to be filed by them and except for taxes and assessments being
         contested in good faith and against which reserves satisfactory to the
         Borrower's independent certified public accountants have been
         established, have paid or caused to be paid all taxes as shown on said
         returns or on





                                       48

         any assessment received by them, to the extent that such taxes have
         become due;

                  (i) Other Agreements. Neither the Borrower nor any Subsidiary
         is

                           (i) a party to any judgment, order, decree or any
                  agreement or instrument or subject to restrictions materially
                  adversely affecting the business, properties or assets,
                  operation or condition (financial or otherwise) of the
                  Borrower or of any Subsidiary; or

                           (ii) in default in the performance, observance or
                  fulfillment of any of the obligations, covenants or conditions
                  contained in any agreement or instrument to which the Borrower
                  or any Subsidiary is a party, which default has, or if not
                  remedied within any applicable grace period could have, a
                  material adverse effect on the business, operations or
                  condition, financial or otherwise, of the Borrower or any
                  Subsidiary;

                  (j) Litigation. Except as set forth in Schedule 6.01(j)
         hereto, there is no action, suit or proceeding at law or in equity or
         by or before any governmental instrumentality or agency or arbitral
         body pending, or, to the knowledge of the Borrower, threatened by or
         against the Borrower or any Subsidiary or affecting the Borrower or any
         Subsidiary or any properties or rights of the Borrower or any
         Subsidiary, which could reasonably be expected to materially adversely

         (12 C.F.R. Part 221), of the Board. The proceeds of the borrowings made
         pursuant to Article II hereof will be used by the Borrower only for the
         purposes set forth in Section 2.12 hereof. None of such proceeds will
         be used, directly or indirectly, for the purpose of purchasing or
         carrying any margin stock or for the purpose of reducing or retiring
         any Indebtedness which was originally incurred to purchase or carry
         margin stock or for any other purpose which might constitute any of the
         Loans under this Agreement a "purpose credit" within the meaning of
         said Regulation U or Regulation X (12 C.F.R. Part 224) of the Board.
         Neither the Borrower nor any agent acting in its behalf has taken or
         will take any action which might cause this Agreement or any of the
         documents or instruments delivered pursuant hereto to violate any
         regulation of the Board or to violate the Securities Exchange Act of
         1934, as amended, or the Securities Act of 1933, as amended, or any
         state securities laws, in each case as in effect on the date hereof;





                                       49

                  (l) Investment Company. Neither the Borrower nor any
         Subsidiary is an "investment company," or an "affiliated person" of, or
         "promoter" or "principal underwriter" for, an "investment company," as
         such terms are defined in the Investment Company Act of 1940, as
         amended (15 U.S.C. Section 80a-1, et seq.). The application of the
         proceeds of the Loans and repayment thereof by the Borrower and the
         performance by the Borrower of the transactions contemplated by this
         Agreement will not violate any provision of said Act, or any rule,
         regulation or order issued by the Securities and Exchange Commission
         thereunder, in each case as in effect on the date hereof;

                  (m) Patents, Etc. The Borrower and its Subsidiaries own or

         material patents, licenses, franchises, trademarks, trademark rights,
         trade names, trade name rights, trade secrets and copyrights necessary
         to the conduct of their businesses as now conducted, without known
         conflict with any patent, license, franchise, trademark, trade secrets
         and confidential commercial or proprietary information, trade name,
         copyright, rights to trade secrets or other proprietary rights of any
         other Person;

                  (n) No Untrue Statement. Neither this Agreement nor any other
         Loan Document or certificate or document executed and delivered by or
         on behalf of the Borrower in accordance with or pursuant to any Loan
         Document contains any misrepresentation or untrue statement of material
         fact or omits to state a material fact necessary, in light of the
         circumstance under which it was made, in order to make any such
         representation or statement contained therein not misleading in any
         material respect;

                  (o) No Consents, Etc. Neither the respective businesses or
         properties of the Borrower or any Subsidiary, nor any relationship
         between the Borrower or any Subsidiary and any other Person, nor any
         circumstance in connection with the execution, delivery and performance
         of the Loan Documents and the transactions contemplated hereby is such
         as to require a consent, approval or authorization of, or filing,
         registration or qualification with, any governmental or other authority
         or any other Person on the part of the Borrower or any Subsidiary as a
         condition to the execution, delivery and performance of, or
         consummation of the transactions contemplated by, this Agreement or the
         other Loan Documents or if so, such consent, approval, authorization,
         filing, registration or qualification has been obtained or effected, as
         the case may be;

         Subsidiary shall disaffirm or seek to disaffirm any such agreement or
         any of its obligations thereunder; or

                  (m) if Borrower shall not qualify as of the date of the
         initial Advance and at all times thereafter as a REIT; or

                  (n) the payment or redemption of or the occurrence of any
         event giving rise to the right to require payment or redemption of any
         Subordinated Indebtedness; or

                  (o) if at any time more than 50% of outstanding securities of
         the Borrower having voting rights in the election of directors (i) is
         owned by a Person or group of Persons acting together or in concert
         with one another or (ii) is owned beneficially by five (5) or less
         Persons;

then, and in any such event and at any time thereafter, if such Event of
Default or any other Event of Default shall have not been waived,

                      (A) either or both of the following actions may be
                  taken: (i) the Agent, with the consent of the Required
                  Lenders, may, and at the direction of the Required Lenders
                  shall, declare any obligation of the Lenders to make further
                  Loans or of NationsBank to issue Letters of Credit terminated,
                  whereupon the obligation of each Lender to make further Loans
                  or of NationsBank to make Swing Line Loans or issue Letters of
                  Credit, hereunder shall terminate immediately, and (ii) the
                  Agent shall at the direction of the Required Lenders, at their
                  option, declare by notice to the Borrower any or all of the
                  Obligations to be immediately due and payable, and the same,
                  including all interest accrued thereon and all other
                  obligations of the Borrower to the Agent and the Lenders,
                  shall forthwith become immediately due and payable without
                  presentment, demand, protest, notice or other formality of any
                  kind, all of which are hereby expressly waived, anything
                  contained herein or in any





                                       70
<PAGE>   76

                  instrument evidencing the Obligations to the contrary
                  notwithstanding; provided, however, that notwithstanding the
                  above, if there shall occur an Event of Default under clause
                  (g) or (h) above, then the obligation of the Lenders to lend
                  and NationsBank to make Swing Line Loans and to issue Letters
                  of Credit hereunder shall automatically terminate and any and
                  all of the Obligations shall be immediately due and payable
                  without the necessity of any action by the Agent or the
                  Required Lenders or notice to the Agent or the Lenders;

                           (B) the Borrower shall, upon demand of the Agent or
                  the Required Lenders, deposit cash with the Agent in
                  accordance with the LC Account Agreement in an amount equal to
                  the amount of any Letters of Credit remaining undrawn or
                  unpaid, as collateral security for the repayment of any future
                  drawings or payments under such Letters of Credit and the
                  Borrower shall forthwith deposit and pay such amounts and such
                  amounts shall be held by the Agent pursuant to the terms of
                  the applicable Application and Agreement for Letter of Credit;
                  and

                           (C) the Agent and the Lenders shall have all of the
                  rights and remedies available under the Loan Documents or
                  under any applicable law.

         9.02 Agent to Act. In case any one or more Events of Default shall
occur and not have been waived, the Agent may, and at the direction of the
Required Lenders shall, proceed to protect and enforce their rights or remedies
either by suit in equity or by action at law, or both, whether for the specific
performance of any covenant, agreement or other provision contained herein or in
any other Loan Document, or to enforce the payment of the Obligations or any
other legal or equitable right or remedy.

         9.03 Cumulative Rights. No right or remedy herein conferred upon the
Lenders or the Agent is intended to be exclusive of any other rights or remedies
contained herein or in any other Loan Document, and every such right or remedy
shall be cumulative and shall be in addition to every other such right or remedy
contained herein and therein or now or hereafter existing at law or in equity or
by statute, or otherwise.

         9.04 No Waiver. No course of dealing between the Borrower and any
Lender or the Agent or any failure or delay on the part of any Lender or the
Agent in exercising any rights or remedies under any Loan Document or otherwise
available to it shall operate as a waiver of any rights or remedies and no
single or partial exercise of any rights or remedies shall operate as a waiver
or preclude the exercise of any other rights or remedies hereunder or of the
same right or remedy on a future occasion.





                                       71

         9.05 Default. The Agent and the Lenders shall have no right to
accelerate any of the Loans upon, or to institute any action or proceeding
before any court to realize upon collateral as a result of, the occurrence of
any Default which shall not also constitute an Event of Default; provided,
however, nothing contained in this sentence shall in any respect impair or
adversely affect the right, power and authority of the Agent and the Lenders (i)
to take any action expressly required or permitted to be taken under the Loan
Documents upon the occurrence of any Default (and including any action or
proceeding which the Agent may determine to be necessary or appropriate in
furtherance of any such expressly authorized action) and (ii) to take any action
provided under the Loan Documents or otherwise available by statute, at law or
in equity upon the occurrence of any Default.

         9.06 Allocation of Proceeds. If an Event of Default has occurred and
not been waived, and the maturity of the Notes has been accelerated pursuant to
Article IX hereof, all payments received by the Agent hereunder, in respect of
any principal of or interest on the Obligations or any other amounts payable by
the Borrower hereunder shall be applied by the Agent in the following order:

              (i) amounts due to the Lenders pursuant to Sections 2.09,
3.03, 7.15, 11.05 and 11.11 hereof;

              (ii) amounts due to (A) NationsBank pursuant to Section 3.04
hereof, and (B) the Agent pursuant to Section 10.11 hereof;

              (iii) payments of interest on Loans, Swing Line Loans and
Reimbursement Obligations, to be applied for the ratable benefit of the Lenders
(with amounts payable in respect of Swing Line Outstandings being included in
such calculation and paid to NationsBank);

              (iv) payments of principal on Loans, Swing Line Loans and
Reimbursement Obligations, to be applied for the ratable benefit of the Lenders
(with amounts payable in respect of Swing Line Outstandings being included in
such calculation and paid to NationsBank);

              (v) payment of cash amounts to the Agent in respect of
Outstanding Letters of Credit pursuant to Section 9.01(B) hereof;

              (vi) payment of Obligations owed a Lender or Lenders pursuant
to Swap Agreements on a pro rata basis according to amounts owed;

              (vii) payments of all other amounts due under this Agreement,
if any, to be applied for the ratable benefit of the Lenders; and





                                       72
<PAGE>   78

                  (viii) any surplus remaining after application as provided for
herein, to the Borrowers or otherwise as may be required by applicable law.

                                   ARTICLE X

                                   The Agent

         10.01 Appointment. Each Lender (including NationsBank in its capacity
as issuer of the Letters of Credit) hereby irrevocably designates and appoints
NationsBank as the Agent of the Lenders under this Agreement, and each of the
Lenders hereby irrevocably authorizes NationsBank as the Agent for such Lender,
to take such action on its behalf under the provisions of this Agreement and the
other Loan Documents and to exercise such powers as are expressly delegated to
the Agent by the terms of this Agreement, together with such other powers as are
reasonably incidental thereto. The Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any of the Lenders, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise exist against the Agent.

         10.02 Attorneys-in-fact. The Agent may execute any of its duties under
this Agreement by or through agents or attorneys-in-fact and shall be entitled
to advice of counsel concerning all matters pertaining to such duties. The Agent
shall not be responsible for the negligence, gross negligence or willful
misconduct of any agents or attorneys-in-fact selected by it with reasonable
care.

         10.03 Limitation on Liability. Neither the Agent nor any of its
officers, directors, employees, agents or attorneys-in-fact shall be liable to
the Lenders for any action lawfully taken or omitted to be taken by it or them
under or in connection with this Agreement except for its or their own gross
negligence or willful misconduct. Neither the Agent nor any of its affiliates
shall be responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by the Borrower or any of its
Subsidiaries, or any officer or representative thereof contained in this
Agreement or in any of the other Loan Documents, or in any certificate, report,
statement or other document referred to or provided for in or received by the
Agent under or in connection with this Agreement, or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any of the other Loan Documents, or for any failure of the Borrower to perform
its obligations thereunder, or for any recitals, statements, representations or
warranties made, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of any collateral. The Agent shall not be under
any obligation to any of the Lenders to ascertain or to inquire as to the
observance or performance of any of the terms, covenants or conditions of this
Agreement or any of the other Loan Documents on the part of the Borrower or to
inspect the properties, books or records of the Borrower or its Subsidiaries.





                                       74
<PAGE>   80

         10.04 Reliance. The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any Note, writing, resolution, notice, consent
certificate, affidavit, letter, cablegram, telegram, telecopy or telex message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to the Borrower), independent accountants and other experts
selected by the Agent. The Agent may deem and treat the payee of any Note as the
owner thereof for all purposes unless an Assignment and Acceptance shall have
been filed with and accepted by the Agent. The Agent shall be fully justified in
failing or refusing to take any action under this Agreement unless it shall
first receive advice or concurrence of the Lenders or the Required Lenders as
provided in this Agreement or it shall first be indemnified to its satisfaction
by the Lenders against any and all liability and expense which may be incurred
by it by reason of taking or continuing to take any such action. The Agent shall
in all cases be fully protected in acting, or in refraining from acting, under
this Agreement and the other Loan Documents in accordance with a request of the
Required Lenders, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all present and
future holders of the Notes.

         10.05 Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has received notice from a Lender, the Authorized
Representative or the Borrower referring to this Agreement, describing such
Default or Event of Default and stating that such notice is a "notice of
default". In the event that the Agent receives such a notice, the Agent shall
promptly give notice thereof to the Lenders. The Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably directed
by the Required Lenders; provided that, unless and until the Agent shall have
received such directions, the Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Event of
Default as it shall deem advisable in the best interests of the Lenders.

         10.06 No Representations. Each Lender expressly acknowledges that
neither the Agent nor any of its affiliates has made any representations or
warranties to it and that no act by the Agent hereafter taken, including any
review of the affairs of the Borrower or any of its Subsidiaries, shall be
deemed to constitute any representation or warranty by the Agent to any Lender.
Each Lender represents to the Agent that it has, independently and without
reliance upon the Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the financial condition, creditworthiness, affairs, status
and nature of the Borrower and its Subsidiaries and made its own decision to
enter into this Agreement. Each Lender also represents that it will,





                                       75
<PAGE>   81

independently and without reliance upon the Agent or any other Lender, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in
taking or not taking action under this Agreement and to make such investigation
as it deems necessary to inform itself as to the status and affairs, financial
or otherwise, of the Borrower and its Subsidiaries.  Except for notices,
reports and other documents expressly required to be furnished to the Lenders
by the Agent hereunder, the Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs,
financial condition or business of the Borrower or any of its Subsidiaries
which may come into the possession of the Agent or any of its affiliates.

         10.07 Indemnification. The Lenders agree to indemnify the Agent in its
capacity as such (to the extent not reimbursed by the Borrower or its
Subsidiaries and without limiting any obligations of the Borrower or any
Subsidiary so to do), ratably according to the respective principal amount of
the Notes held by them (or, if no Notes are outstanding, ratably in accordance
with their respective Applicable Commitment Percentages as then in effect) from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may at any time (including without limitation at any
time following the payment of the Notes) be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement or any
other document contemplated by or referred to herein or the transactions
contemplated hereby or any action taken or omitted by the Agent under or in
connection with any of the foregoing; provided that no Lender shall be liable
for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Agent's gross negligence or willful misconduct. The
agreements in this subsection shall survive the payment of the Obligations and
the termination of this Agreement.

         10.08 Lender. The Agent and its affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Borrower and
its Subsidiaries as though it were not the Agent hereunder. With respect to its
Loans made or renewed by it and any Note issued to it, the Agent shall have the
same rights and powers under this Agreement as any Lender and may exercise the
same as though it were not the Agent, and the terms "Lender" and "Lenders"
shall, unless the context otherwise indicates, include the Agent in its
individual capacity.

         10.09 Resignation. If the Agent shall resign as Agent under this
Agreement, then the Required Lenders may appoint, with the consent, so long as
there shall not have occurred and be continuing a Default or Event of Default,
of the Borrower, which consent shall





                                       76
<PAGE>   82

not be unreasonably withheld, a successor Agent for the Lenders, which
successor Agent shall be a commercial bank organized under the laws of the
United States or any state thereof, having a combined surplus and capital of
not less than $500,000,000, whereupon such successor Agent shall succeed to the
rights, powers and duties of the former Agent and the obligations of the former
Agent shall be terminated and canceled, without any other or further act or
deed on the part of such former Agent or any of the parties to this Agreement;
provided, however, that the former Agent's resignation shall not become
effective until such successor Agent has been appointed and has succeeded of
record to all right, title and interest in any collateral held by the Agent;
provided, further, that if the Required Lenders and, if applicable, the
Borrower cannot agree as to a successor Agent within ninety (90) days after
such resignation, the Agent shall appoint a successor Agent which satisfies the
criteria set forth above in this Section 10.09 for a successor Agent and the
parties hereto agree to execute whatever documents are necessary to effect such
action under this Agreement or any other document executed pursuant to this
Agreement; provided, however that in such event all provisions of this
Agreement and the Loan Documents, shall remain in full force and effect.  After
any retiring Agent's resignation hereunder as Agent, the provisions of this
Article X shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent under this Agreement.

         10.10 Sharing of Payments, etc. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, set-off, counterclaim or
otherwise, obtain payment with respect to its Obligations (other than pursuant
to Article IV) which results in its receiving more than its pro rata share of
the aggregate payments with respect to all of the Obligations (other than any
payment pursuant to Article IV), then (A) such Lender shall be deemed to have
simultaneously purchased from the other Lenders a share in their Obligations so
that the amount of the Obligations held by each of the Lenders shall be pro rata
and (B) such other adjustments shall be made from time to time as shall be
equitable to insure that the Lenders share such payments ratably; provided,
however, that for purposes of this Section 10.10 the term "pro rata" shall be
determined with respect to both the Revolving Credit Commitment of each Lender
and to the Total Revolving Credit Commitments after subtraction in each case of
amounts, if any, by which any such Lender has not funded its share of the
outstanding Loans and Reimbursement Obligations. If all or any portion of any
such excess payment is thereafter recovered from the Lender which received the
same, the purchase provided in this Section 10.10 shall be rescinded to the
extent of such recovery, without interest. The Borrower expressly consents to
the foregoing arrangements and agrees that each Lender so purchasing a portion
of the other Lenders' Obligations may exercise all rights of payment (including,
without limitation, all rights of set-off, banker's lien or counterclaim) with
respect to such portion as fully as if such Lender were the direct holder of
such portion.





                                       77
<PAGE>   83


         10.11 Fees. At such time as there shall be more than one Lender
hereunder and at all times thereafter, the Borrower agrees to pay to the Agent,
for its individual account, an annual Agent's fee in an amount as agreed to by
the Agent and the Borrower, such fee to be paid quarterly in advance commencing
on the first day after the date there shall be more than one Lender.

                                   ARTICLE XI

                                 Miscellaneous

         11.01 Assignments and Participations.

         (a) At any time after the Closing Date each Lender may, with the prior
consent of the Agent and, so long as no Default or Event of Default exists
hereunder, the Borrower, which consents shall not be unreasonably withheld (it
being understood that consent may be withheld by the Borrower if such assignment
would subject the Borrower to the payment of any additional amounts pursuant to
the provisions of Section 4.06 hereof), assign to one or more banks or financial
institutions all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of the Note payable to its
order); provided, that (i) each such assignment shall be of a constant, and not
a varying, percentage of all of the assigning Lender's rights and obligations
(including Loans and Participations) under this Agreement, (ii) for each
assignment involving the issuance and transfer of a Note, the assigning Lender
shall execute an Assignment and Acceptance and the Borrower hereby consents to
execute a replacement Note to give effect to the assignment, (iii) the minimum
Revolving Credit Commitment which shall be assigned is $5,000,000 (together with
which the assigning Lender's applicable portion of Participations and the Letter
of Credit Commitment shall also be assigned) and (iv) such assignee shall have
an office located in the United States. Upon such execution, delivery, approval
and acceptance, from and after the effective date specified in each Assignment
and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder or under such Note have been
assigned or negotiated to it pursuant to such Assignment and Acceptance have the
rights and obligations of a Lender hereunder and a holder of such Note and (y)
the assignor thereunder shall, to the extent that rights and obligations
hereunder or under such Note have been assigned or negotiated by it pursuant to
such Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement. No assignee shall have the right to further
assign its rights and obligations pursuant to this Section 11.01. Any Lender who
makes an assignment shall pay to the Agent a one-time administrative fee of
$2,500.00 which fee shall not be reimbursed by the Borrower.

         (b) By executing and delivering an Assignment and Acceptance, the
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) the assignment made
under such Assignment and Acceptance is made under such Assignment and
Acceptance without recourse; (ii) such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to the financial
condition of the Borrower or any Subsidiary or the performance or observance by
the Borrower or any Subsidiary of any of its obligations under any Loan Document
or any other instrument





                                       79
<PAGE>   85

or document furnished pursuant hereto; (iii) such assignee confirms that it has
received a copy of this Agreement, together with copies of the financial
statements delivered pursuant to Section 6.01(f) or Section 7.01, as the case
may be, and such other Loan Documents and 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 Agent, such assigning Lender or any other Lender 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 appoints and authorizes the Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement, the Notes and the other Loan Documents as are delegated to the Agent
by the terms hereof and thereof, together with such powers as are reasonably
incidental thereto; and (vi) 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 and a holder of such
Notes.

         (c) The Agent shall maintain at its address referred to herein a copy
of each Assignment and Acceptance delivered to and accepted by it.

         (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender, the Agent shall give prompt notice thereof to Borrower.

         (e) Each Lender may sell participations at its expense to one or more
banks or other entities as to all or a portion of its rights and obligations
under this Agreement; provided, that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any Note issued to it for the
purpose of this Agreement, (iv) such participations shall be in a minimum amount
of $1,000,000 and shall include an allocable portion of such Lender's
Participation, and (v) Borrower, the Agent and the other Lenders shall continue
to deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement and with regard to any and all
payments to be made under this Agreement; provided, that the participation
agreement between a Lender and its participants may provide that such Lender
will obtain the approval of such participant prior to such Lender's agreeing to
any amendment or waiver of any provisions of this Agreement which would (A)
extend the maturity of any Note, (B) reduce the interest rate hereunder, or (C)
increase the Revolving Credit Commitment of the Lender granting the
participation other than as permitted by Section 2.07, and (vi) the sale of any
such participations which require Borrower to file a registration statement with
the United States Securities and Exchange Commission or under the securities
regulations or laws of any state shall not be permitted.





                                       80
<PAGE>   86


         (f) Notwithstanding anything to the contrary contained herein or in any
of the other Loan Documents, any Lender may assign all or any portion of its
rights and obligations under the Loan Documents and the Notes to any affiliate
of such Lender, and any Lender may pledge all or any portion of its interest
under the Loan Documents and the Notes to any Federal Reserve Bank as security
for obligations of such Lender to such Federal Reserve Bank, without the consent
of the Borrower, the Agent or any other Lender and without the payment of the
administrative fee referred to in Section 11.01(a).

         11.02 Notices. Except as provided below, any notice shall be
conclusively deemed to have been received by any party hereto and be effective
on the day on which delivered to such party (against receipt therefor) at the
address set forth below or such other address as such party shall specify to the
other parties in writing (or, in the case of telephonic notice or notice by

                          hereof and on the signature page of each Assignment
                          and Acceptance.

         11.03 Setoff. The Borrower agrees that the Agent and each Lender shall
have a lien for all the Obligations of the Borrower upon all deposits or deposit
accounts, of any kind, or any interest in any deposits or deposit accounts
thereof, now or hereafter pledged, mortgaged, transferred or assigned to the
Agent or such Lender or otherwise in the possession or control of the Agent or
such Lender (other than for safekeeping) for any purpose for the account or
benefit of the Borrower and including any balance of any deposit account or of
any credit of the Borrower with the Agent or such Lender, whether now existing
or hereafter established, hereby authorizing the Agent and each Lender at any
time or times with or without prior notice to apply such balances or any part
thereof to such of the Obligations of the Borrower to the Lenders then past due
and in such amounts as they may elect, and whether or not the collateral or the
responsibility of other Persons primarily, secondarily or otherwise liable may
be deemed adequate. For the purposes of this paragraph, all remittances and
property shall be deemed to be in the possession of the Agent or such Lender as
soon as the same may be put in transit to it by mail or carrier or by other
bailee.

         11.04 Survival. All covenants, agreements, representations and
warranties made herein shall survive the making by the Lenders of the Loans and
the expiration of the Letters of Credit and the execution and delivery to the
Lenders of this Agreement and the Notes and shall continue in full force and
effect so long as any of Obligations remain outstanding or any Lender has any
commitment





                                       82
<PAGE>   88

hereunder or the Borrower has continuing obligations hereunder unless otherwise
provided herein. Whenever in this Agreement, any of the parties hereto is
referred to, such reference shall be deemed to include the successors and
permitted assigns of such party and all covenants, provisions and agreements by
or on behalf of the Borrower which are contained in this Agreement, the Notes
and the other Loan Documents shall inure to the benefit of the successors and
permitted assigns of the Lenders or any of them.

         11.05 Expenses. The Borrower agrees (a) to pay or reimburse the Agent
for all its reasonable and customary out-of-pocket costs and expenses incurred
in connection with the preparation, negotiation and execution of, this Agreement
or any of the other Loan Documents (including travel expenses relating to
closing), and the consummation of the transactions contemplated hereby and
thereby, including, without limitation, the reasonable and customary fees and
disbursements of counsel to the Agent, as well as all such expenses and costs
arising in connection with any amendment, supplement or modification to this
Agreement or any other Loan Documents, (b) to pay or reimburse the Agent and the
Lenders for all their reasonable costs and expenses incurred in connection with
the enforcement or preservation of any rights under this Agreement and the other
Loan Documents, including without limitation, the reasonable fees and
disbursements of their counsel and any payments in indemnification or otherwise
payable by the Lenders to the Agent pursuant to the Loan Documents, (c) to pay,
indemnify and hold the Agent and the Lenders harmless from any and all recording
and filing fees and any and all liabilities with respect to, or resulting from
any failure to pay or delay in paying, documentary, stamp, excise and other
similar taxes, if any, which may be payable or determined to be payable in
connection with the execution and delivery of this Agreement or any other Loan
Documents, or consummation of any amendment, supplement or modification of, or
any waiver or consent under or in respect of, this Agreement or any other Loan
Documents, and (d) to pay, indemnify, and hold the Agent and the Lenders
harmless from and against any and all other liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever with respect to the execution, delivery,
enforcement, performance and administration of this Agreement and the other Loan
Documents or in any respect relating to the transactions contemplated hereby or
thereby, (all the foregoing, collectively, the "indemnified liabilities");
provided, however, that the Borrower shall have no obligation hereunder with
respect to indemnified liabilities arising from (i) the willful misconduct or
gross negligence of or the willful breach of the Loan Documents by the party
seeking indemnification, (ii) legal proceedings commenced against the Agent or
any Lender by any security holder or creditor thereof arising out of and based
upon rights afforded any such security holder or creditor solely in its capacity
as such, (iii) any taxes imposed upon the Agent or any Lender other than the
documentary, stamp, excise and similar taxes described in clause (c) above or
any tax resulting from any





                                       83
<PAGE>   89

Regulatory Change, which tax would be payable to Lenders by Borrower pursuant
to Article IV hereof, (iv) taxes imposed and costs and expenses incurred as a
result of a transfer or assignment of any Note, participation or assignment of
a portion of its rights or (v) any taxes imposed upon or any costs or expenses
incurred by any transferee of any Note.  The agreements in this subsection
shall survive repayment of the Notes and all other Obligations hereunder and
termination of this Agreement.

         11.06 Amendments. No amendment, modification or waiver of any provision
of this Agreement or any of the Loan Documents and no consent by the Lenders to
any departure therefrom by the Borrower shall be effective unless such
amendment, modification or waiver shall be in writing and signed by the Agent,
but only upon having received the written consent of the Required Lenders, and
the same shall then be effective only for the period and on the conditions and
for the specific instances and purposes specified in such writing; provided,
however, that, no such amendment, modification or waiver

                 (i)  which changes, extends or waives any provision of Section
         10.10 or this Section 11.06, the amount of or the due date of any
         scheduled installment of or the rate of interest payable on any
         Obligation or the amount of any fees payable to Lenders, changes the
         definition of Required Lenders, which permits an assignment by
         Borrower of its Obligations hereunder, which reduces the required
         consent of Lenders provided hereunder (other than as provided in
         Section 4.05 hereof), which increases, decreases or extends the
         Revolving Credit Commitment of any Lender or which increases or
         extends the Letter of Credit Facility or which waives any condition to
         the making of any Loan shall be effective unless in writing and signed
         by each of the Lenders; provided, however, the Required Lenders may in
         their sole discretion waive any Default or Event of Default (other
         than any Event of Default under Section 9.01(a), (b), (g) or (h));

                  (ii) which releases any Subsidiary from its Subsidiary
         Guaranty shall be effective unless with the written consent of each of
         the Lenders;

                  (iii) which affects the rights, privileges or obligations of
         NationsBank as provider of Swing Line Loans and issuer of Letters of
         Credit, shall be effective unless signed in writing by NationsBank; or

                  (iv) which affects the rights, privileges, immunities or
         indemnities of the Agent shall be effective unless in writing and
         signed by the Agent.

Notwithstanding any provision of the other Loan Documents to the contrary, as
between the Agent and the Lenders, execution by the Agent shall not be deemed
conclusive evidence that the Agent has





                                       84
<PAGE>   90

obtained the written consent of the Required Lenders. No notice to or demand on
the Borrower in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances, except as otherwise
expressly provided herein. No delay or omission on any Lender's or the Agent's
part in exercising any right, remedy or option shall operate as a waiver of such
or any other right, remedy or option or of any Default or Event of Default.

         11.07 Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed an
original, and it shall not be necessary in making proof of this Agreement to
produce or account for more than one such fully-executed counterpart.

         11.08 Waivers by Borrower. In any litigation in any court with respect
to, in connection with, or arising out of this Agreement, the Loans, any of the
Notes, any of the other Loan Documents, the Obligations, or any instrument or
document delivered pursuant to this Agreement or the other Loan Documents, or
the validity, protection, interpretation, collection or enforcement thereof, or
any other claim or dispute howsoever arising between the Borrower and the
Lenders or the Agent, the Borrower and each Lender and the Agent hereby waive,
to the extent permitted by applicable law, trial by jury in connection with any
such litigation.

         The Borrower, the Agent and the Lenders believe that, inasmuch as this
Agreement and the transactions contemplated hereby have been entered into and
consummated outside the State of Alabama, such transactions constitute
transactions in interstate commerce, so that neither the Agent nor any of the
Lenders is required, solely by entering into this Agreement and consummating
the transactions contemplated hereby, to qualify to do business as a foreign
corporation within the State of Alabama.  Notwithstanding the foregoing,
however, the Borrower hereby irrevocably waives all rights that it may have to
raise, in any action brought by any of the Lenders or the Agent to enforce the
rights of the Lenders and the Agent hereunder or under any of the other Loan
Documents, or the obligations of the Borrower hereunder or thereunder, any
defense which is based upon the failure of any of the Lenders or the Agent to
qualify to do business as a foreign corporation in the State of Alabama,
including, but not limited to, any defenses based upon Section 232 of the
Alabama Constitution of 1901, Section  10-2B-15.01 of the Code of Alabama
(1975) or Section 40-14-4 of the Code of Alabama (1975), or any successor
provision to any thereof.  The foregoing waiver is made knowingly and
voluntarily and is a material inducement for the Agent and the Lenders to enter
into the transactions contemplated by this Agreement or any of the other Loan
Documents.

         11.09 Termination. The termination of this Agreement shall not affect
any rights of the Borrower, the Lenders or the Agent or





                                       85
<PAGE>   91

any obligation of the Borrower, the Lenders or the Agent, arising prior to the
effective date of such termination, and the provisions hereof shall continue to
be fully operative until all transactions entered into or rights created or
obligations incurred prior to such termination have been fully disposed of,
concluded or liquidated and the Obligations arising prior to or after such
termination have been irrevocably paid in full.  The rights granted to the
Agent for the benefit of the Lenders hereunder and under the other Loan
Documents shall continue in full force and effect, notwithstanding the
termination of this Agreement, until all of the Obligations have been paid in
full after the termination hereof (other than Obligations in the nature of
continuing indemnities or expense reimbursement obligations not yet due and
payable) or the Borrower has furnished the Lenders and the Agent with an
indemnification satisfactory to the Agent and each Lender with respect thereto.
All representations, warranties, covenants, waivers and agreements contained
herein shall survive termination hereof until payment in full of the
Obligations unless otherwise provided herein.  Notwithstanding the foregoing,
if after receipt of any payment of all or any part of the Obligations, any
Lender is for any reason compelled to surrender such payment to any Person
because such payment is determined to be void or voidable as a preference,
impermissible setoff, a diversion of trust funds or for any other reason, this
Agreement shall continue in full force and the Borrower shall be liable to, and
shall indemnify and hold such Lender harmless for, the amount of such payment
surrendered until such Lender shall have been finally and irrevocably paid in
full.  The provisions of the foregoing sentence shall be and remain effective
notwithstanding any contrary action which may have been taken by the Lenders in
reliance upon such payment, and any such contrary action so taken shall be
without prejudice to the Lenders' rights under this Agreement and shall be
deemed to have been conditioned upon such payment having become final and
irrevocable.

         11.10 Governing Law. ALL DOCUMENTS EXECUTED PURSUANT TO THE
TRANSACTIONS CONTEMPLATED HEREIN, INCLUDING, WITHOUT LIMITATION, THIS AGREEMENT
AND EACH OF THE LOAN DOCUMENTS SHALL BE DEEMED TO BE CONTRACTS MADE UNDER, AND
FOR ALL PURPOSES SHALL BE CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS AND
JUDICIAL DECISIONS OF THE STATE OF GEORGIA. THE BORROWER HEREBY SUBMITS TO THE
JURISDICTION AND VENUE OF THE STATE AND FEDERAL COURTS OF GEORGIA FOR THE
PURPOSES OF RESOLVING DISPUTES HEREUNDER OR FOR THE PURPOSES OF COLLECTION.

         11.11 Indemnification. (a) In consideration of the execution and
delivery of this Agreement by the Agent and each Lender and the extension of the
Revolving Credit Commitments, the Borrower hereby indemnifies, exonerates and
holds the Agent and each Lender and each of their respective officers,
directors, employees and agents (collectively, the "Indemnified Parties") free
and harmless from and against any and all actions, causes of





                                       86
<PAGE>   92

action, suits, losses, costs, liabilities and damages, and expenses
incurred in connection therewith (irrespective of whether any such
Indemnified Party is a party to the action for which indemnification hereunder
is sought), including reasonable attorneys' fees and disbursements
(collectively, the "Indemnified Liabilities"), incurred by the Indemnified
Parties or any of them as a result of, or arising out of, or relating to any
transaction financed or to be financed in whole or in part, directly or
indirectly, with the proceeds of any Loan (including any Swing Line Loan) or
supported by any Letter of Credit, except for any such Indemnified Liabilities
arising for the account of a particular Indemnified Party by reason of the bad
faith, gross negligence or willful misconduct of, or willful breach of the Loan
Documents by, such Indemnified Party or an officer, co-officer, director,
co-director, employee, co-employee, agent or co-agent of such Indemnified Party
or a transfer or disposition of a Note by an Indemnified Party, and if and to
the extent that the foregoing undertaking may be unenforceable for any reason,
the Borrower hereby agrees to make the maximum contribution to the payment and
satisfaction of each of the Indemnified Liabilities which is permissible under
applicable law.

         (b)  If a claim is to be made by a party entitled to indemnification
under this Section 11.11 or Section 7.15 against the indemnifying party, the
party entitled to such indemnification shall give written notice to the
indemnifying party promptly after the party entitled to indemnification
receives actual notice of any claim, action, suit, loss, cost, liability,
damage or expense incurred or instituted for which the indemnification is
sought.  If requested by the Borrower in writing, and so long as no Default or
Event of Default shall have occurred and be continuing, such indemnitee shall
contest the validity, applicability and/or amount of such suit, action, or
cause of action to the extent such contest may be conducted in good faith on
legally supportable grounds.  If any lawsuit or enforcement action is filed
against any party entitled to the benefit of indemnity under this Section
11.11, written notice thereof shall be given to the indemnifying party as soon
as practicable (and in any event within 15 days after the service of the
citation or summons).  Notwithstanding the foregoing, the failure so to notify
the indemnifying party as provided in this Section 11.11 will relieve
indemnifying party from liability hereunder only if and to the extent that such
failure results in the forfeiture by the indemnifying party of substantive
rights and defenses.  After such notice, if the indemnifying party shall
acknowledge in writing to the indemnified party that the indemnifying party
shall be obligated under the terms of its indemnity hereunder in connection
with such lawsuit or action, then, so long as no Default or Event of Default
shall occur and be continuing, the indemnifying party shall be entitled, if it
so elects, to take control of the defense and investigation of such lawsuit or
action and to employ and engage counsel of its own choice reasonably acceptable
to the indemnified party to handle and defend the same, at the indemnifying
party's cost, risk and





                                       87
<PAGE>   93

expense, provided, however, that the indemnifying party and its counsel
shall proceed with diligence and in good faith with respect thereto.  If (i)
the engagement of such counsel by the indemnifying party would present a
conflict of interest which would prevent such counsel from effectively
defending such action on behalf of the indemnified party, (ii) the defendants
in, or targets of, any such lawsuit or action include both the indemnified
party and indemnifying party, and the indemnified party reasonably concludes
that there may be legal defenses available to it that are different from or in
addition to those available to the indemnifying party, (iii) the indemnifying
party fails to assume the defense of the lawsuit or action or to employ counsel
reasonably satisfactory to such indemnified party, in either case in a timely
manner, or (iv) a Default or Event of Default shall occur and be continuing,
then such indemnified party may employ separate counsel to represent or defend
it in any such action or proceeding and the indemnifying party will pay the
fees and disbursements of such counsel, provided, however, that each indemnitee
shall endeavor, but shall not be obligated, in connection with any matter
covered by this Section 11.11 which also involves other indemnities, to use
reasonable efforts to avoid unnecessary duplication of efforts by counsel for
all indemnities and provided further, that in no event shall the Borrowers be
liable for the fees and expenses of more than one separate firm for the
indemnified parties.  The indemnified party shall cooperate (with all out of
pocket costs and expenses associated therewith to be paid by the indemnifying
party) in all reasonable respects with the indemnifying party and such
attorneys in the investigation, trial and defense of such lawsuit or action and
any appeal arising therefrom; provided, however, that the indemnified party
may, at its own cost (except as set forth in, and in accordance with, the
foregoing sentence), participate in the investigation, trial and defense of
such lawsuit or action and any appeal arising therefrom.  If the indemnifying
party has acknowledged to the indemnified party its obligation to indemnify
hereunder, the indemnified party, so long as no Default or Event of Default
shall have occurred and be continuing, shall not settle such lawsuit or
enforcement action without the prior written consent of the indemnifying party
and, if the indemnifying party has not so acknowledged its obligation, the
indemnified party shall not settle such lawsuit or enforcement action within 20
days' prior written notice to the indemnifying party.

         11.12 Headings and References. The headings of the Articles and
Sections of this Agreement are inserted for convenience of reference only and
are not intended to be a part of, or to affect the meaning or interpretation of
this Agreement. Words such as "hereof", "hereunder", "herein" and words of
similar import shall refer to this Agreement in its entirety and not to any
particular Section or provisions hereof, unless so expressly specified. As used
herein, the singular shall include the plural, and the masculine shall include
the feminine or a neutral gender, and vice versa, whenever the context requires.





                                       88
<PAGE>   94

         11.13 Severability. If any provision of this Agreement or the other
Loan Documents shall be determined to be illegal or invalid as to one or more of
the parties hereto, then such provision shall remain in effect with respect to
all parties, if any, as to whom such provision is neither illegal nor invalid,
and in any event all other provisions hereof shall remain effective and binding
on the parties hereto.

         11.14 Entire Agreement. This Agreement, together with the other Loan
Documents, constitutes the entire agreement between the parties with respect to
the subject matter hereof and supersedes all previous proposals, negotiations,
representations, commitments and other communications between or among the
parties, both oral and written, with respect thereto.

         11.15 Agreement Controls. In the event that any term of any of the Loan
Documents other than this Agreement conflicts with any term of this Agreement,
the terms and provisions of this Agreement shall control.

         11.16 Usury Savings Clause. Notwithstanding any other provision herein,
the aggregate interest rate charged under any of the Notes, including all
charges or fees in connection therewith deemed in the nature of interest under
Georgia law, shall not exceed the Highest Lawful Rate (as such term is defined
below). If the rate of interest (determined without regard to the preceding
sentence) under this Agreement at any time exceeds the Highest Lawful Rate (as
defined below), the outstanding amount of the Loans made hereunder shall bear
interest at the Highest Lawful Rate until the total amount of interest due
hereunder equals the amount of interest which would have been due hereunder if
the stated rates of interest set forth in this Agreement had at all times been
in effect. In addition, if when the Loans made hereunder are repaid in full the
total interest due hereunder (taking into account the increase provided for
above) is less than the total amount of interest which would have been due
hereunder if the stated rates of interest set forth in this Agreement had at all
times been in effect, then to the extent permitted by law, the Borrower shall
pay to the Agent an amount equal to the difference between the amount of
interest paid and the amount of interest which would have been paid if the
Highest Lawful rate had at all times been in effect. Notwithstanding the
foregoing, it is the intention of the Lenders and the Borrower to conform
strictly to any applicable usury laws. Accordingly, if any lender contracts for,
charges, or receives any consideration which constitutes interest in excess of
the Highest Lawful rate, then any such excess shall be canceled automatically
and, if previously paid, shall at such Lender's option be applied to the
outstanding amount of the Loans made hereunder or be refunded to the Borrower.
As used in this paragraph, the term "Highest Lawful Rate" means the maximum
lawful interest rate, if any, that at any time or from time to time may be
contracted for, charged, or received under the laws applicable to such Lender
which are presently in effect or, to the extent allowed by law, under such
applicable laws which may hereafter be in effect and which allow a higher
maximum nonusurious interest rate than applicable laws now allow.
