Lenders severally agrees to make the portion of the Tranche A Loans and the
Tranche B Loans to the Borrower from time to time during the Commitment Period
in an amount up to such Lender's Commitment as is set






<PAGE>   5
forth adjacent to such Lender's name in Schedule 1.1 hereto for the purpose of
enabling the Borrower to purchase the Properties and to pay Property
Acquisition Costs, Property Costs and Transaction Expenses, provided, that the
aggregate principal amount at any one (1) time outstanding with respect to each
of the Tranche A Loans and the Tranche B Loans shall not exceed the amount of
the Tranche A Commitments and the Tranche B Commitments respectively.  Any
prepayments of the Loans, whether mandatory or at the Borrower's election,
shall not be subject to reborrowing except as set forth in Section 5.2(d) of
the Participation Agreement.

         (b)     The Loans may from time to time be (i) Eurodollar Loans, (ii)
ABR Loans, or (iii) a combination thereof, as determined by the Borrower and
notified to the Agent in accordance with Sections 2.3 and 2.7.  In the event
the Borrower fails to provide notice pursuant to Section 2.3, the Loan shall be
an ABR Loan.  Further, any Loans by the Lenders on a given date in an aggregate
amount less than $100,000 shall be ABR Loans, unless the remaining Available
Commitment for the Lenders in the aggregate is less than $100,000, in which
case, the Borrower may elect a Eurodollar Loan for such remaining amount.

         (c)     The Commitment of each Lender to make Tranche A Loans and
Tranche B Loans shall be pro rata.

         2.2     NOTES.

         The Loans made by each Lender shall be evidenced by promissory notes
of the Borrower, substantially in the form of EXHIBIT A-1 in the case of the
Tranche A Loans (each, a "Tranche A Note") or EXHIBIT A-2 in the case of the
Tranche B Loans (each, a "Tranche B Note," and with the Tranche A Notes, the
"Notes"), with appropriate insertions as to payee, date and principal amount,
payable to the order of such Lender and in a principal amount equal to the
Tranche A Commitment or Tranche B Commitment, as the case may be, of such
Lender.  Each Lender is hereby authorized to record the date, Type and amount
of each Loan made by such Lender, each continuation thereof, each conversion of
all or a portion thereof to another Type, and the date and amount of each
payment or prepayment of principal thereof on the schedule annexed to and
constituting a part of its Note, and any such recordation shall constitute
prima facie evidence of the accuracy of the information so recorded, provided,
that the failure to make any such recordation or any error in such recordation
shall not affect the Borrower's obligations hereunder or under such Note.  Each
Note shall (i) be dated the Initial Closing Date, (ii) be stated to mature on
the Maturity Date and (iii) provide for the payment of principal in accordance
with Section 2.6(d) and the payment of interest in accordance with Section 2.8.

         2.3     PROCEDURE FOR BORROWING.

         (a)     The Borrower may borrow under the Commitments during the
Commitment Period on any Business Day that an Advance may be requested pursuant
to the terms of Section 5.2 of the Participation Agreement, provided, that the
Borrower shall give the Agent irrevocable notice (which must be received by the
Agent prior to 12:00 Noon, Charlotte, North Carolina time, at least five (5)
Business Days prior to the requested Borrowing Date specifying (i) the





                                       2
<PAGE>   6
amount to be borrowed (which on any date shall not be in excess of the then
Available Commitments), (ii) the requested Borrowing Date, (iii) whether the
borrowing is to be of Eurodollar Loans, ABR Loans or a combination thereof,
(iv) if the borrowing is to be a combination of Eurodollar Loans and ABR Loans,
the respective amounts of each Type of Loan and (v) the Interest Period
applicable to each Eurodollar Loan.  Pursuant to the terms of the Participation
Agreement, the Borrower shall be deemed to have delivered such notice upon the
delivery of a notice by the Construction Agent or the Lessee containing such
required information.  Upon receipt of any such notice from the Borrower, the
Agent shall promptly notify each Lender thereof.  Each Lender will make the
amount of its pro rata share of each borrowing available to the Agent for the
account of the Borrower at the office of the Agent specified in Section 9.2
prior to 12:00 Noon, Charlotte, North Carolina time, on the Borrowing Date
requested by the Borrower in funds immediately available to the Agent.  Such
borrowing will then be made available to the Borrower by the Agent crediting an
account designated, subject to Section 9.1 of the Participation Agreement, by
the Borrower on the books of such office with the aggregate of the amounts made
available to the Agent by the Lenders and in like funds as received by the
Agent.  No amount of any Loan which is repaid or prepaid by the Borrower may be
reborrowed hereunder, except as set forth in Section 5.2(d) of the
Participation Agreement.

         (b)     Interest accruing on each Loan during the Construction Period
with respect to any Property shall, subject to the limitations set forth in
Section 5.1(b) of the Participation Agreement be added to the principal amount
of such Loan on the relevant Scheduled Interest Payment Date.  On each such
Scheduled Interest Payment Date, the Loan Property Cost and Construction Loan
Property Cost shall be increased by the amount of interest added to the Loans.

         2.4     (INTENTIONALLY OMITTED)

         2.5     TERMINATION OR REDUCTION OF COMMITMENTS.

         (a)     The Borrower shall have the right, upon not less than three
(3) Business Days' written notice to the Agent, to terminate the Commitments
or, from time to time, to reduce the amount of the Commitments, provided, that
(i) after giving effect to such reduction, the aggregate outstanding principal
amount of the Loans shall not exceed the aggregate Commitments and (ii) such
notice shall be accompanied by a certificate of the Construction Agent stating
that the amount equal to ninety-seven percent (97%) of aggregate Budgeted Total
Property Costs as of the date of such reduction does not exceed the aggregate
amount of Available Commitments as of such date after giving effect to such
reduction.  Any such reduction (A) shall be in an amount equal to the lesser of
(1) $1,000,000 (or an even multiple thereof) or (2) the remaining Available
Commitments, (B) shall reduce permanently the Commitments then in effect and
(C) shall be pro rata for the Commitments of all Lenders and pro rata between
the Tranche A Loans and the Tranche B Loans.

         (b)     The Commitments respecting any particular Property shall
automatically be reduced to zero (0) sixty (60) days after the occurrence of
the Rent Commencement Date respecting such Property.  On any date on which the
Commitments shall automatically be





                                       3
<PAGE>   7
reduced to zero (0) pursuant to Section 6, the Borrower shall prepay all
outstanding Loans, together with accrued unpaid interest thereon and all other
amounts owing thereunder.

         2.6     PREPAYMENTS AND PAYMENTS.

         (a)     Subject to Sections 11.2(e), 11.3 and 11.4 of the
Participation Agreement, the Borrower may at any time and from time to time
prepay the Loans, in whole or in part, without premium or penalty, upon at
least three (3) Business Days' irrevocable notice to the Agent, specifying the
date and amount of prepayment and whether the prepayment is of Eurodollar
Loans, ABR Loans or a combination thereof, and, if a combination thereof, the
amount allocable to each.  Upon receipt of any such notice the Agent shall
promptly notify each Lender thereof.  If any such notice is given, the amount
specified in such notice shall be due and payable on the date specified
therein.  Amounts prepaid may not be reborrowed, and shall reduce the
Commitments and the Available Commitments, except in each case as set forth in
Section 5.2(d) of the Participation Agreement.

         (b)     If on any date the Agent or the Lessor shall receive any
payment in respect of (i) any Casualty, Condemnation or Environmental Violation
pursuant to Sections 15.1(a) or 15.1(g) or Article XVI of the Lease (excluding
any payments in respect thereof which are payable to the Lessee in accordance
with the Lease), or (ii) the Termination Value of any Property in connection
with the delivery of a Termination Notice pursuant to Article XVI of the Lease,
or (iii) the Termination Value of any Property in connection with the exercise
of the Purchase Option under Article XX of the Lease or the exercise of the
option of the Lessor to transfer the Properties to the Lessee pursuant to
Section 20.3 of the Lease, or (iv) any payment required to be made or elected
to be made by the Construction Agent to the Lessor pursuant to the terms of the
Agency Agreement, then in each case, the Borrower shall pay such amounts to the
Agent and the Agent shall be required to apply and pay such amounts in
accordance with the provisions of Section 8.7(b)(ii) of the Participation
Agreement.

         (c)     Each prepayment of the Loans pursuant to Section 2.6(a) shall
be allocated to reduce the respective Loan Property Costs of all Properties pro
rata according to the Loan Property Costs of such Properties immediately before
giving effect to such prepayment.  Each prepayment of the Loans pursuant to
Section 2.6(b) shall be allocated to reduce the Loan Property Cost of the
Property or Properties subject to the respective Casualty, Condemnation,
Environmental Violation, termination, purchase, transfer or other circumstance
giving rise to such prepayment.  Any amounts applied to reduce the Loan
Property Cost of any Construction Period Property pursuant to this paragraph
(c) shall also be applied to reduce the Construction Loan Property Cost of such
Property until such Construction Loan Property Cost has been reduced to zero
(0).

         (d)     On each date referenced in Schedule 1 to the Participation

         (e)     The outstanding principal balance of the Loans and all other
amounts then due and owing under this Agreement or otherwise with respect to
the Loans shall be due and payable in full on the Maturity Date.

         2.7     CONVERSION AND CONTINUATION OPTIONS.

         (a)     The Borrower may elect from time to time to convert Eurodollar
Loans to ABR Loans by giving the Agent at least three (3) Business Days' prior
irrevocable notice of such election, provided, that any such conversion of
Eurodollar Loans may only be made on the last day of an Interest Period with
respect thereto, and provided, further, to the extent a Credit Agreement Event
of Default has occurred and is continuing on the last day of any such Interest
Period, the applicable Eurodollar Loan shall automatically be converted to an
ABR Loan.  The Borrower may elect from time to time to convert ABR Loans to
Eurodollar Loans by giving the Agent at least three (3) Business Days' prior
irrevocable notice of such election.  Upon receipt of any such notice, the
Agent shall promptly notify each Lender thereof.  All or any part of
outstanding Eurodollar Loans or ABR Loans may be converted as provided herein,
provided, that (i) no ABR Loan may be converted into a Eurodollar Loan after
the date that is one (1) month prior to the Maturity Date and (ii) such notice
of conversion regarding any Eurodollar Loan shall contain an election by the
Borrower of an Interest Period for such Eurodollar Loan to be created by such
conversion and such Interest Period shall be in accordance with the terms of
the definition of the term "Interest Period" including without limitation
subparagraphs (A) through (D) thereof.

         (b)     Subject to the restrictions set forth in Section 2.3 hereof,
any Eurodollar Loan may be continued as such upon the expiration of the current
Interest Period with respect thereto by the Borrower giving irrevocable notice
to the Agent, in accordance with the applicable notice provision for the
conversion of ABR Loans to Eurodollar Loans set forth herein, of the length of
the next Interest Period to be applicable to such Loans, provided, that no
Eurodollar Loan may be continued as such after the date that is one (1) month
prior to the Maturity Date, provided, further, no Eurodollar Loans may be
continued as such if a Credit Agreement Event of Default has occurred and is
continuing as of the last day of the Interest Period for such Eurodollar Loan,
and provided, further, that if the Borrower shall fail to give any required
notice as described above or otherwise herein, or if such continuation is not
permitted pursuant to the proceeding proviso, such Loan shall automatically be
converted to an ABR Loan on the last day of such then expiring Interest Period.

         2.8     INTEREST RATES AND PAYMENT DATES.

         (a)     The Loans outstanding hereunder from time to time shall bear
interest at a rate per annum equal to either (i) with respect to a Eurodollar
Loan, the Eurodollar Rate determined for the applicable Interest Period plus
the Applicable Percentage or (ii) with respect to an ABR Loan, the ABR, as
selected by the Borrower in accordance with the provisions hereof; provided,
however, (A) upon delivery by the Agent of the notice described in Section
2.9(c), the Loans of each of the Lenders shall bear interest at the ABR
applicable from time to time from and after the dates and during the periods
specified in Section 2.9(c), (B) upon the delivery by a Lender of the





                                       5
<PAGE>   9
notice described in Section 11.3(f) of the Participation Agreement, the Loans
of such Lender shall bear interest at the ABR applicable from time to time from
and after the dates and during the periods specified in Section 11.3(f) of the
Participation Agreement and (C) in such other circumstances as expressly
provided herein, the Loans shall bear interest at the ABR.

         (b)     If all or a portion of (i) the principal amount of any Loan,
(ii) any interest payable thereon or (iii) any other amount payable hereunder
shall not be paid when due (whether at the stated maturity, by acceleration or
otherwise), such overdue amount shall bear interest at a rate per annum which
is the lesser of (x) the then current rate of interest respecting such payment
plus two percent (2%) and (y) the highest interest rate permitted by applicable
law, in each case from the date of such non-payment until such amount is paid
in full (whether after or before judgment).

         (c)     Interest shall be payable in arrears on the applicable
Scheduled Interest Payment Date, provided, that (i) interest accruing pursuant
to paragraph (b) of this Section 2.8 shall be payable from time to time on
demand and (ii) each prepayment of the Loans shall be accompanied by accrued
interest to the date of such prepayment on the amount prepaid.

         2.9     COMPUTATION OF INTEREST.

         (a)     Whenever it is calculated on the basis of the Prime Lending
Rate, interest shall be calculated on the basis of a year of three hundred
sixty-five (365) days (or three hundred sixty-six (366) days, as the case may
be) for the actual days elapsed; and, otherwise, interest shall be calculated
on the basis of a year of three hundred sixty (360) days for the actual days
elapsed.  The Agent shall as soon as practicable notify the Borrower and the
Lenders of each determination of a Eurodollar Rate.  Any change in the interest
rate on a Loan resulting from a change in the ABR or the Eurocurrency Reserve
Requirements shall become effective as of the day on which such change becomes
effective.  The Agent shall as soon as practicable notify the Borrower and the
Lenders of the effective date and the amount of each such change in interest
rate.

         (b)     Each determination of an interest rate by the Agent pursuant
to any provision of this Agreement shall be conclusive and binding on the
Borrower and the Lenders in the absence of manifest error.

         (c)     If the Eurodollar Rate cannot be determined by the Agent in
the manner specified in the definition of the term "Eurodollar Rate", the Agent
shall give telecopy or telephonic notice thereof to the Borrower and the
Lenders as soon as practicable thereafter.  Until such time as the Eurodollar
Rate can be determined by the Agent in the manner specified in the definition
of such term, no further Eurodollar Loans shall be made or shall be continued
as such at the end of the then current Interest Period nor shall the Borrower
have the right to convert ABR Loans to Eurodollar Loans.

         2.10    PRO RATA TREATMENT AND PAYMENTS.

         (a)     Each borrowing by the Borrower from the Lenders hereunder and
any reduction of the Commitments of the Lenders shall be made pro rata
according to their respective Commitments.  Subject to the provisions of
Section 8.7 of the Participation Agreement and Section 2.11(b) hereof, each
payment (including without limitation each prepayment) by the Borrower on
account of principal of and interest on the Loans shall be made pro rata
according to the respective outstanding principal amounts on the Loans then
held by the Lenders.  All payments (including without limitation prepayments)
to be made by the Borrower hereunder and under the Notes, whether on account of
principal, interest or otherwise, shall be made without setoff or counterclaim
and shall be made prior to 12:00 Noon, Charlotte, North Carolina time, on the
due date thereof to the Agent, for the account of the Lenders, at the Agent's
office specified in Section 9.2, in Dollars and in immediately available funds.
The Agent shall distribute such payments to the Lenders promptly upon receipt
in like funds as received.  If any payment hereunder becomes due and payable on
a day other than a Business Day, such payment shall be extended to the next
succeeding Business Day; provided, however, if such payment includes an amount
of interest calculated with reference to the Eurodollar Rate and the result of
such extension would be to extend such payment into another calendar month,
then such payment shall be made on the immediately preceding Business Day.  In
the case of any extension of any payment of principal pursuant to the preceding
two (2) sentences, interest thereon shall be payable at the then applicable
rate during such extension.

         (b)     Unless the Agent shall have been notified in writing by any
Lender prior to a borrowing that such Lender will not make its share of such
borrowing available to the Agent, the Agent may assume that such Lender is
making such amount available to the Agent, and the Agent may, in reliance upon
such assumption, make available to the Borrower a corresponding amount.  If
such amount is not made available to the Agent by the required time on the
Borrowing Date therefor, such Lender shall pay to the Agent, on demand, such
amount with interest thereon at a rate equal to the daily average Federal Funds
Effective Rate for the period until such Lender makes such amount immediately
available to the Agent.  A certificate of the Agent submitted to any Lender
with respect to any amounts owing under this Section 2.10(b) shall be
conclusive in the absence of manifest error.  With respect to any Lender other
than First Union National Bank (if any), to the extent any such Lender's share
of such borrowing is not made available to the Agent by such Lender within
three (3) Business Days of such Borrowing Date, the Agent shall also be
entitled to recover such amount with interest thereon at the rate as set forth
above on demand from the Borrower.

         2.11    NOTICE OF AMOUNTS PAYABLE; MANDATORY ASSIGNMENT.

         (a)     In the event that any Lender becomes aware that any amounts
are or will be owed to it pursuant to Sections 11.2(e), 11.3 or 11.4 of the
Participation Agreement or that it is unable to make Eurodollar Loans, then it
shall promptly notify the Borrower, the Lessee and the Agent thereof and, as
soon as possible thereafter, such Lender shall submit to the Borrower (with a
copy to the Agent) a certificate indicating the amount owing to it and the
calculation thereof.  The





                                       7
<PAGE>   11
amounts set forth in such certificate shall be, absent manifest error, prima
facie evidence of the obligations of the Borrower hereunder.

         (b)     In the event that any Lender delivers to the Borrower a
certificate in accordance with Section 2.11(a) in connection with amounts
payable pursuant to Sections 11.2(e), 11.3 or 11.4 of the Participation
Agreement or such Lender is required to make Loans as ABR Loans in accordance
with Section 11.3(d) of the Participation Agreement then, subject to Section
9.1 of the Participation Agreement, the Borrower may, at its own expense
(provided, such amounts shall be reimbursed or paid entirely (as elected by the
Borrower) by the Lessee, as Supplemental Rent) and in the discretion of the
Borrower, (i) require such Lender to transfer or assign, in whole or (with such
Lender's consent) in part, without recourse (in accordance with Section 9.8),
all or (with such Lender's consent) part of its interests, rights (except for
rights to be indemnified for actions taken while a party hereunder) and
obligations under this Agreement to a replacement bank or institution if the
Borrower (subject to Section 9.1 of the Participation Agreement), with the full
cooperation of such Lender, can identify a Person who is ready, willing and
able to be such replacement bank or institution with respect thereto and such
replacement bank or institution (which may be another Lender) shall assume such
assigned obligations, or (ii) during such time as no Credit Agreement Default
or Credit Agreement Event of Default has occurred and is continuing, terminate
the Commitment of such Lender and prepay all outstanding Loans of such Lender;
provided, however, that (x) subject to Section 9.1 of the Participation
Agreement, the Borrower or such replacement bank or institution, as the case
may be, shall have paid to such Lender in immediately available funds the
principal of and interest accrued to the date of such payment on the Loans made
by it hereunder and all other amounts owed to it hereunder (and, if such Lender
is also a Holder, all Holder Advances and Holder Yield accrued and unpaid
thereon), (y) any termination of the Commitment of such Lender shall be pro
rata for such Lender's Tranche A Commitment and such Lender's Tranche B
Commitment and further subject to the terms of the first sentence of Section
2.5(a) and clause (B) of the second sentence of Section 2.5(a) and (z) such
assignment or termination of the Commitment of such Lender and prepayment of
Loans does not conflict with any law, rule or regulation or order of any court
or Governmental Authority.

         To induce the Agent and the Lenders to enter into this Agreement and

         7.1     APPOINTMENT.

         Each Lender hereby irrevocably designates and appoints the Agent as
the agent of such Lender under this Agreement and the other Operative
Agreements, and each such Lender irrevocably authorizes the Agent, in such
capacity, to execute the Operative Agreements as agent for and on behalf of

of this Agreement and the other Operative Agreements and to exercise such
powers and perform such duties as are expressly delegated to the Agent by the

perform such duties as are delegated to the Agent thereunder without being
required to obtain any specific consent with respect thereto from any Lender,

Agreement, the Agent shall not have any duties or responsibilities, except
those expressly set forth herein, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other
Operative Agreement or otherwise exist against the Agent.

         7.2     DELEGATION OF DUTIES.

         The Agent may execute any of its duties under this Agreement and the
other Operative Agreements 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 or misconduct of
any agents or attorneys-in-fact selected by it with reasonable care.

         7.3     EXCULPATORY PROVISIONS.

         Neither the Agent nor any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates shall be (a) liable for any action
lawfully taken or omitted to be taken by it or such Person under or in
connection with this Agreement or any other Operative Agreement (except for its
or such Person's own gross negligence or willful misconduct) or (b) responsible
in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by the Borrower or the Lessee or any officer
thereof contained in this Agreement or any other Operative Agreement 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 any
other Operative Agreement or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other
Operative Agreement or for any failure of the Borrower or the Lessee to perform
its obligations hereunder or thereunder.  The Agent shall not be under any
obligation to any Lender to ascertain or to inquire as to the observance or





                                       14

<PAGE>   18
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Operative Agreement, or to inspect the properties, books
or records of the Borrower or the Lessee.

         7.4     RELIANCE BY THE AGENT.

         The Agent shall be entitled to rely, and shall be fully protected in
relying, upon any Note, writing, resolution, notice, consent, certificate,
affidavit, letter, telecopy, telex or teletype 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 or the Lessee), 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 a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Agent.  The Agent shall be
fully justified in failing or refusing to take any action under this Agreement
or any other Operative Agreement unless it shall first receive such advice or
concurrence of the Majority Lenders, the Majority Secured Parties or all
Secured Parties, as the case may be, as it deems appropriate 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
Operative Agreements in accordance with a request of the Majority Lenders, the
Majority Secured Parties or all Secured Parties, as the case may be, and such
and any action taken or failure to act pursuant thereto shall be binding upon
all the Lenders and all future holders of the Notes (or all Secured Parties, as
the case may be).

         7.5     NOTICE OF DEFAULT.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Credit Agreement Default or Credit Agreement Event of Default
hereunder unless the Agent has received written notice from a Lender or the
Borrower referring to this Agreement, describing such Credit Agreement Default
or Credit Agreement 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 give notice thereof to the Lenders.  The Agent shall take such action
with respect to such Credit Agreement Default or Credit Agreement Event of
Default as shall be reasonably directed by the Majority Secured Parties;
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 Credit Agreement Default or Credit
Agreement Event of Default as it shall deem advisable in the best interests of
the Secured Parties; provided, further, the foregoing shall not limit (a) the
rights of the Majority Secured Parties to elect remedies as set forth in
Section 6 and/or (b) the rights of the Majority Secured Parties or all Secured
Parties, as the case may be, as described in the Participation Agreement
(including without limitation Sections 8.2(h) and 8.6 of the Participation
Agreement).

<PAGE>   19
         7.6     NON-RELIANCE ON THE AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that neither the Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates has
made any representations or warranties to it and that no act by the Agent
hereinafter taken, including without limitation any review of the affairs of
the Borrower or the Lessee, 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 business, operations, property,
financial and other condition and creditworthiness of the Borrower and the
Lessee and made its own decision to make its Loans hereunder and enter into
this Agreement.  Each Lender also represents that it will, 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 the other Operative Agreements, and to make
such investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrower and the Lessee.  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 business, operations, property,
condition (financial or otherwise), prospects or creditworthiness of the
Borrower or the Lessee which may come into the possession of the Agent or any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

         7.7     INDEMNIFICATION.

         The Lenders agree to indemnify the Agent, in its capacity as such (to
the extent not reimbursed by the Borrower and without limiting the obligation
of the Borrower to do so), ratably according to their respective Commitment
Percentages in effect on the date on which indemnification is sought under this
Section 7.7 (or, if indemnification is sought after the date upon which the
Commitments shall have terminated and the Loans shall have been paid in full,
ratably in accordance with their Commitment Percentages immediately prior to
such date), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind 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 any of them in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Operative Agreements or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by any of them
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, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting solely from the gross negligence or willful misconduct
of the Agent.  The agreements in this Section 7.7 shall survive the payment of
the Notes and all other amounts payable hereunder.





                                       16

<PAGE>   20
         7.8     THE AGENT IN ITS INDIVIDUAL CAPACITY.

         The Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrower or the Lessee as
though the Agent were not the Agent hereunder and under the other Operative
Agreements.  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 and the other Operative Agreements as any Lender and may exercise the
same as though it were not the Agent, and the terms "Lender" and "Lenders"
shall include the Agent in its individual capacity.

         7.9     SUCCESSOR AGENT.

         The Agent may resign at any time as the Agent upon thirty (30) days'
notice to the Lenders, the Borrower and, so long as no Lease Event of Default
shall have occurred and be continuing, the Lessee.  If the Agent shall resign
as the Agent under this Agreement, the Majority Lenders shall appoint from
among the Lenders a successor Agent which successor Agent shall be subject to
the approval of the Borrower and, so long as no Lease Event of Default shall
have occurred and be continuing, the Lessee, such approval not to be
unreasonably withheld or delayed.  If no successor Agent is appointed prior to
the effective date of the resignation of the resigning Agent, the Agent may
appoint, after consulting with the Lenders and subject to the approval of the
Borrower and, so long as no Lease Event of Default shall have occurred and be
continuing, the Lessee, such approval not to be unreasonably withheld or
delayed, a successor Agent from among the Lenders.  If no successor Agent has
accepted appointment as the Agent by the date which is thirty (30) days
following a retiring Agent's notice of resignation, the retiring Agent's notice
of resignation shall nevertheless thereupon become effective and the Lenders
shall perform all of the duties of the Agent until such time, if any, as the
Majority Lenders appoint a successor Agent, as provided for above.  Upon the
effective date of such resignation, only such successor Agent shall succeed to
all the rights, powers and duties of the retiring Agent and the term "Agent"
shall mean such successor agent and the retiring Agent's rights, powers and
duties in such capacity shall be terminated.  After any retiring Agent resigns
hereunder as the Agent, the provisions of this Article VII and Section 9.5
shall inure to their respective benefit as to any actions taken or omitted to
be taken by it while it was the Agent under this Agreement.

         7.10    ACTIONS OF THE AGENT ON BEHALF OF HOLDERS.

         The parties hereto specifically acknowledge and consent to the Agent's
acting on behalf of the Holders as provided in the Participation Agreement,
and, in any such case, the Lenders acknowledge that the Holders shall be
entitled to vote as "Secured Parties" hereunder to the extent required or
permitted by the Operative Agreements (including without limitation Sections
8.2(h) and 8.6 of the Participation Agreement).

         7.11    THE AGENT'S DUTY OF CARE.

         Other than the exercise of reasonable care to assure the safe custody
of the Collateral while being held by the Agent hereunder or under any other
Operative Agreement, the Agent





                                       17

<PAGE>   21

shall have no duty or liability to preserve rights pertaining thereto,
it being understood and agreed that the Lessee shall be responsible for
preservation of all rights in the Collateral, and the Agent shall be relieved
of all responsibility for the Collateral upon surrendering it or tendering the
surrender of it to the Lessee. The Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that
which the Agent accords its own property, which shall be no less than the
treatment employed by a reasonable and prudent agent in the industry, it being
understood that the Agent shall not have responsibility for taking any
necessary steps to preserve rights against any parties with respect to any of
the Collateral.


             SECTION 8.  MATTERS RELATING TO PAYMENT AND COLLATERAL

         8.1     COLLECTION AND ALLOCATION OF PAYMENTS AND OTHER AMOUNTS.

         The Lessee, the Construction Agent, the Agent, the Lenders, the
Holders and the Borrower have agreed pursuant to the terms of Section 8.7 of
the Participation Agreement to a procedure for the allocation and distribution
of certain payments and distributions, including without limitation the
proceeds of Collateral.

         8.2     CERTAIN REMEDIAL MATTERS.

         Notwithstanding any other provision of this Agreement or any other
Credit Document:

         (a)     the Borrower shall at all times retain to the exclusion of all
other parties, all rights to Excepted Payments payable to it and to demand,
collect or commence an action at law to obtain such payments and to enforce any
judgment with respect thereto; and

         (b)     the Borrower and each Holder shall at all times retain the
right, but not to the exclusion of the Agent, (i) to retain all rights with
respect to insurance that Article XIV of the Lease specifically confers upon
the "Lessor", (ii) to provide such insurance as the Lessee shall have failed to
maintain or as the Borrower or any Holder may desire, and (iii) to enforce
compliance by the Lessee with the provisions of Articles VIII, IX, X, XI, XIV
and XVII of the Lease.

         8.3     EXCEPTED PAYMENTS.

         Notwithstanding any other provision of this Agreement or the Security
Documents, any Excepted Payment received at any time by the Agent shall be
distributed promptly to the Person entitled to receive such Excepted Payment.

         No failure to exercise and no delay in exercising, on the part of the
Agent or any Lender, any right, remedy, power or privilege hereunder or under
the other Credit Documents shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or future exercise thereof or the exercise of any other
right, remedy, power or privilege.  The rights, remedies, powers and privileges
herein provided are cumulative and not exclusive of any rights, remedies,
powers and privileges provided by law.

         9.4     SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

         All representations and warranties made by the Borrower under the
Operative Agreements shall survive the execution and delivery of this Agreement
and the Notes and the making of the Loans hereunder.

         9.5     PAYMENT OF EXPENSES AND TAXES.

         The Borrower agrees to (with funds provided by the Lessee as
Supplemental Rent):  (a) pay all reasonable out-of-pocket costs and expenses of
(i) the Agent whether or not the transactions herein contemplated are
consummated, in connection with the negotiation, preparation, execution and
delivery of the Operative Agreements and the documents and instruments referred
to therein (including without limitation the reasonable fees and disbursements
of Moore & Van Allen, PLLC) and any amendment, waiver or consent relating
thereto (including without limitation the reasonable fees and disbursements of
counsel to the Agent) and (ii) the Agent and each of the Lenders in connection
with the enforcement of the Operative Agreements and the documents and
instruments referred to therein (including without limitation the reasonable
fees and disbursements of counsel for the Agent and for each of the Lenders)
and (b) pay and hold each of the Lenders harmless from and against any and all
present and future stamp and other similar taxes with respect to the foregoing
matters and save each of the Lenders harmless from and against any all
liabilities with respect to or resulting from any delay or omission (other than
to the extent attributable to such Lender) to pay such taxes.

<PAGE>   23
         9.6     SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS.

         This Agreement shall be binding upon and inure to the benefit of the
Borrower, the Lenders, the Agent, all future holders of the Notes and their
respective successors and assigns, except that the Borrower may not assign or
transfer any of its rights or obligations under this Agreement without the
prior written consent of each Lender.

         9.7     PARTICIPATIONS.

         Subject to and in accordance with Section 10.1 of the Participation
Agreement, any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time sell to one (1) or more banks,
financial institutions or other entities (each, a "Participant") participating
interests in any Loan owing to such Lender, any Note held by such Lender, any
Commitment of such Lender or any other interest of such Lender hereunder and
under the other Operative Agreements; provided, that any such sale of a
participating interest shall be in a principal amount of at least $2,000,000 or
such lesser amount constituting such Lender's entire interest in this Agreement
and the Notes.  In the event of any such sale by a Lender of a participating
interest to a Participant, such Lender's obligations under this Agreement to
the other parties to this Agreement shall remain unchanged, such Lender shall
remain solely responsible for the performance thereof, such Lender shall remain
the holder of any such Note for all purposes under this Agreement and the
Notes, and the Borrower and the Agent shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the Notes.  In no event shall any
Participant have any right to approve any amendment or waiver of any provision
of this Agreement or any other Operative Agreement, or any consent to any
departure by the Borrower or any other Person therefrom, except to the extent
that such amendment, waiver or consent would (a) reduce the principal of, or
interest on, any Loan or Note, or postpone the date of the final maturity of
any Loan or Note, in each case to the extent subject to such participation or
(b) release all or substantially all of the Collateral.  The Borrower agrees
that, while a Credit Agreement Event of Default shall have occurred and be
continuing, if amounts outstanding under this Agreement and the Notes are due
or unpaid, or shall have become due and payable upon the occurrence of a Credit
Agreement Event of Default, each Participant shall, to the maximum extent
permitted by applicable law, be deemed to have the right of setoff in respect
of its participating interests in amounts owing directly to it as a Lender
under this Agreement or any Note, provided, that in purchasing such
participating interest, such Participant shall be deemed to have agreed to
share with the Lenders the proceeds thereof as provided in Section 9.10(a) as
fully as if it were a Lender hereunder.  The Borrower also agrees that each
Participant shall be entitled to the benefits of Sections 11.2(e), 11.3 and
11.4 of the Participation Agreement with respect to its participation in the
Commitments and the Loans outstanding from time to time as if it was a Lender;
provided, that such Participant shall have complied with the requirements of
said Sections and provided, further, that no Participant shall be entitled to
receive any greater amount pursuant to any such Section than the transferor
Lender would have been entitled to receive in respect of the amount of the
participation transferred by such transferor Lender to such Participant had no
such transfer occurred.

         9.8     ASSIGNMENTS.

         (a)     Subject to and in accordance with Section 10.1 of the
Participation Agreement, any Lender may, in the ordinary course of its business
and in accordance with applicable law, at any time and from time to time assign
to any Lender or any Affiliate of any Lender or, with the consent, subject to
Section 9.1 of the Participation Agreement, of the Borrower and the Agent
(which in each case shall not be unreasonably withheld or delayed and which
consent of the Borrower shall not be required during the continuation of any
Credit Agreement Event of Default), to an additional bank, financial
institution or other entity that is either organized under the laws of the
United States or any state thereof or is a foreign bank that operates a branch
office in the United States, (each, a "Purchasing Lender") all or any part of
its rights and obligations under this Agreement and the other Operative
Agreements pursuant to an Assignment and Acceptance, substantially in the form
of EXHIBIT B, executed by such Purchasing Lender, such assigning Lender (and,
in the case of a Purchasing Lender that is not a Lender or an Affiliate
thereof, subject to Section 9.1 of the Participation Agreement, by the Borrower
and the Agent) and delivered to the Agent for its acceptance and recording in
the Register; provided, that no such assignment to a Purchasing Lender (other
than any Lender or any Affiliate thereof) shall be in an aggregate principal
amount less than $5,000,000 (other than in the case of an assignment of all of
a Lender's interests under this Agreement and the Notes).  Upon such execution,
delivery, acceptance and recording, from and after the effective date
determined pursuant to such Assignment and Acceptance, (x) the Purchasing
Lender thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender
hereunder with a Commitment as set forth therein, and (y) the assigning Lender
thereunder shall, to the extent provided in such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all of the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such assigning Lender
shall cease to be a party hereto).  Notwithstanding anything to the contrary in
this Agreement, the consent of the Borrower shall not be required, and, unless
requested by the relevant Purchasing Lender and/or assigning Lender, new Notes
shall not be required to be executed and delivered by the Borrower, for any
assignment which occurs at any time when any of the events described in Section
6(g) shall have occurred and be continuing.

         (b)     Upon its receipt of an Assignment and Acceptance executed by
an assigning Lender and a Purchasing Lender (and, in the case of a Purchasing
Lender that is not a Lender or an Affiliate thereof, by the Borrower and the
Agent) together with payment to the Agent of a registration and processing fee
of $2,500 (which shall not be payable by the Borrower or the Lessee, except as
otherwise provided in connection with an assignment requested in accordance
with Section 2.11(b)), the Agent shall (i) promptly accept such Assignment and
Acceptance and (ii) promptly after the effective date determined pursuant
thereto, record the information contained therein in the Register and give
notice of such acceptance and recordation to the Lenders and the Borrower.  On
or prior to such effective date, the Borrower, at its own expense, shall
execute and deliver to the Agent new Notes (in exchange for the Notes of the
assigning Lender), each in an amount equal to the Commitment assumed or Loans
purchased by the relevant Purchasing Lender pursuant to such Assignment and
Acceptance, and, if the assigning Lender has retained a Commitment or any Loan
hereunder, new Notes to the order of the





                                       21

<PAGE>   25
assigning Lender, each in an amount equal to the Commitment or Loans retained
by it hereunder.  Such new Notes shall be dated the effective date of the
applicable Assignment and Acceptance and shall otherwise be in the form of the
Notes replaced thereby.

         (c)     Each Purchasing Lender (other than any Lender organized and
existing under the laws of the U.S. or any political subdivision in or of the
U.S.), by executing and delivering an Assignment and Acceptance,

                 (i)      agrees to execute and deliver to the Agent, as
promptly as practicable, four (4) signed copies (two (2) for the Agent and two
(2) for delivery by the Agent to the Borrower) of Form 1001 or Form 4224 (or
any successor form or comparable form) (it being understood that if the
applicable form is not so delivered, payments under or in respect of this
Agreement may be subject to withholding and deduction);

                 (ii)     represents and warrants to the Borrower and the Agent
that the form so delivered is true and accurate and that, as of the effective
date of the applicable Assignment and Acceptance, each of such Purchasing
Lender's lending offices is entitled to receive payments of principal and
interest under or in respect of this Agreement without withholding or deduction
for or on account of any taxes imposed by the U.S. Federal government;

                 (iii)    agrees to annually hereafter deliver to each of the
Borrower and the Agent not later than December 31 of the year preceding the
year to which it will apply, two (2) further properly completed signed copies
of Form 1001 or Form 4224 (or any successor form or comparable form), as
appropriate, unless an event has occurred which renders the relevant form
inapplicable (it being understood that if the applicable form is not so
delivered, payments under or in respect of this Agreement may be subject to
withholding and deduction);

                 (iv)     agrees to promptly notify the Borrower and the Agent
in writing if it ceases to be entitled to receive payments of principal and
interest under or in respect of this Agreement without withholding or deduction
for or on account of any taxes imposed by the U.S. or any political subdivision
in or of the U.S. (it being understood that payments under or in respect of
this Agreement may be subject to withholding and deduction in such event);

                 (v)      acknowledges that in the event it ceases to be exempt
from withholding and/or deduction of such taxes, the Agent may withhold and/or
deduct the applicable amount from any payments to which such assignee Lender
would otherwise be entitled, without any liability to such assignee Lender
therefor; and

                 (vi)     agrees to indemnify the Borrower and the Agent from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs or expenses that result from such assignee
Lender's breach of any such representation, warranty or agreement.

         (d)     Any Lender party to this Agreement may, from time to time and
without the consent of the Borrower or any other Person, pledge or assign for
security purposes any portion





                                       22

<PAGE>   26
of its Loans or any other interests in this Agreement and the other Credit
Documents to any Federal Reserve Bank.

         9.9     THE REGISTER; DISCLOSURE; PLEDGES TO FEDERAL RESERVE BANKS.

         (a)     The Agent shall maintain for the benefit of the Lenders at its
address referred to in Section 9.2 a copy of each Assignment and Acceptance
delivered to it and a register (the "Register") for the recordation of the
names and addresses of the Lenders, the Commitments of the Lenders, and the
principal amount of the Loans owing to each Lender from time to time.  The
entries in the Register shall be conclusive, in the absence of clearly
demonstrable error, and the Borrower, the Agent and the Lenders may treat each
Person whose name is recorded in the Register as the owner of the Loan recorded
therein for all purposes of this Agreement.  The Register shall be available
for inspection by the Borrower or any Lender at any reasonable time and from
time to time upon reasonable notice.

         (b)     Nothing herein shall prohibit any Lender from pledging or
assigning any Note to any Federal Reserve Bank in accordance with applicable
law.

         9.10    ADJUSTMENTS; SET-OFF.

         (a)     Except as otherwise expressly provided in Section 8.1 hereof
and Section 8.7 of the Participation Agreement where, and to the extent, one
(1) Lender is entitled to payments prior to other Lenders, if any Lender (a
"Benefitted Lender") shall at any time receive any payment of all or part of
its Loans, or interest thereon, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by set-off, pursuant to events or
proceedings of the nature referred to in Section 6(g), or otherwise), in a
greater proportion than any such payment to or collateral received by any other
Lender, if any, in respect of such other Lender's Loans, or interest thereon,
such Benefitted Lender shall purchase for cash from the other Lenders a
participating interest in such portion of each such other Lender's Loan, or
shall provide such other Lenders with the benefits of any such collateral, or
the proceeds thereof, as shall be necessary to cause such Benefitted Lender to
share the excess payment or benefits of such collateral or proceeds ratably
with each of the Lenders; provided, however, that if all or any portion of such
excess payment or benefits is thereafter recovered from such Benefitted Lender,
such purchase shall be rescinded, and the purchase price and benefits returned,
to the event of such recovery, but without interest.

         (b)     In addition to any rights now or hereafter granted under
applicable law or otherwise, and not by way of limitation of any such rights,
upon the occurrence of a Credit Agreement Event of Default, the Agent and each
Lender is hereby authorized at any time or from time to time, without
presentment, demand, protest or other notice of any kind to the Borrower or to
any other Person, any such notice being hereby expressly waived, to set off and
to appropriate and apply any and all deposits (general or special) and any

         9.16    ACKNOWLEDGEMENTS.

         The Borrower hereby acknowledges that:

         (a)     neither the Agent nor any Lender has any fiduciary
relationship with or duty to the Borrower arising out of or in connection with
this Agreement or any of the other Credit Documents, and the relationship
between the Agent and the Lenders, on one (1) hand, and the Borrower, on the
other hand, in connection herewith or therewith is solely that of debtor and
creditor; and

         (b)     no joint venture is created hereby or by the other Credit
Documents or otherwise exists by virtue of the transactions contemplated hereby
among the Lenders or among the Borrower and the Lenders.

         9.17    WAIVERS OF JURY TRIAL.

         THE BORROWER, THE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT ALLOWED BY APPLICABLE LAW, TRIAL
BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY
OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

         9.18    NONRECOURSE.

         In addition to and not in limitation of Section 12.9 of the
Participation Agreement, anything to the contrary contained in this Agreement
or in any other Operative Agreement notwithstanding, no Exculpated Person shall
be personally liable in any respect for any liability or obligation hereunder
or under any other Operative Agreement including without limitation the payment
of the principal of, or interest on, the Notes, or for monetary damages for the
breach of performance of any of the covenants contained in this Agreement, the
Notes or any of the other Operative Agreements.  The Agent and the Lenders
agree that, in the event any of them pursues any remedies available to them
under this Agreement, the Notes or any other Operative Agreement, neither the
Agent nor the Lenders shall have any recourse against the Borrower, nor any
other Exculpated Person, for any deficiency, loss or claim for monetary damages
or otherwise resulting therefrom and recourse shall be had solely and
exclusively against the Trust Estate and the Lessee; but nothing contained
herein shall be taken to prevent recourse against or the enforcement of
remedies against the Trust Estate in respect of any and all liabilities,
obligations and undertakings contained in this Agreement, the Notes or any
other Operative Agreement.  The Agent and the Lenders further agree that the
Borrower shall not be responsible for the payment of any amounts owing
hereunder (excluding principal and interest (other than Overdue Interest) in
respect of the Loans) (such non-excluded amounts, "Supplemental Amounts")
except to the extent that payments of Supplemental Rent designated by the
Lessee for application to such Supplemental Amounts shall have been paid by the
Lessee pursuant to the Lease (it being understood that the failure by the
Lessee for any reason to pay any Supplemental Rent in respect of such
Supplemental Amounts shall nevertheless be deemed to constitute a





                                       25

<PAGE>   29
default by the Borrower for the purposes of Section 6).  Notwithstanding the
foregoing provisions of this Section 9.18, nothing in this Agreement or any
other Operative Agreement shall (a) constitute a waiver, release or discharge
of any obligation evidenced or secured by this Agreement or any other Credit
Document, (b) limit the right of the Agent or any Lender to name the Borrower
as a party defendant in any action or suit for judicial foreclosure and sale
under any Security Document, or (c) affect in any way the validity or
enforceability of any guaranty (whether of payment and/or performance) given to
the Lessor, the Agent or the Lenders, or of any indemnity agreement given by
the Borrower, in connection with the Loans made hereunder.

         9.19    USURY SAVINGS PROVISION.

         IT IS THE INTENT OF THE PARTIES HERETO TO CONFORM TO AND CONTRACT IN
STRICT COMPLIANCE WITH APPLICABLE USURY LAW FROM TIME TO TIME IN EFFECT AND
THAT N.C. GEN. STAT. Section 24-9 SHALL APPLY WITH RESPECT TO THIS AGREEMENT.
TO THE EXTENT N.C. GEN. STAT.  Section 24-9 IS HEREAFTER DEEMED NOT TO APPLY BY
A COURT OF COMPETENT JURISDICTION AND ANY PAYMENTS HEREUNDER ARE HEREINAFTER
CHARACTERIZED BY ANY COURT OF COMPETENT JURISDICTION AS THE REPAYMENT OF
PRINCIPAL AND INTEREST THEREON, THE FOLLOWING PROVISIONS OF THIS SECTION 9.19
SHALL APPLY.  ANY SUCH PAYMENTS SO CHARACTERIZED AS INTEREST MAY BE REFERRED TO
HEREIN AS "INTEREST."  ALL AGREEMENTS AMONG THE PARTIES HERETO ARE HEREBY
LIMITED BY THE PROVISIONS OF THIS PARAGRAPH WHICH SHALL OVERRIDE AND CONTROL
ALL SUCH AGREEMENTS, WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER
WRITTEN OR ORAL.  IN NO WAY, NOR IN ANY EVENT OR CONTINGENCY (INCLUDING WITHOUT
LIMITATION PREPAYMENT OR ACCELERATION OF THE MATURITY OF ANY OBLIGATION), SHALL
ANY INTEREST TAKEN, RESERVED, CONTRACTED FOR, CHARGED, OR RECEIVED UNDER THIS
AGREEMENT OR OTHERWISE, EXCEED THE MAXIMUM NONUSURIOUS AMOUNT PERMISSIBLE UNDER
APPLICABLE LAW.  IF, FROM ANY POSSIBLE CONSTRUCTION OF ANY OF THE OPERATIVE
AGREEMENTS OR ANY OTHER DOCUMENT OR AGREEMENT, INTEREST WOULD OTHERWISE BE
PAYABLE IN EXCESS OF THE MAXIMUM NONUSURIOUS AMOUNT, ANY SUCH CONSTRUCTION
SHALL BE SUBJECT TO THE PROVISIONS OF THIS PARAGRAPH AND SUCH AMOUNTS UNDER
SUCH DOCUMENTS OR AGREEMENTS SHALL BE AUTOMATICALLY REDUCED TO THE MAXIMUM
NONUSURIOUS AMOUNT PERMITTED UNDER APPLICABLE LAW, WITHOUT THE NECESSITY OF
EXECUTION OF ANY AMENDMENT OR NEW DOCUMENT OR AGREEMENT.  IF THE AGENT OR ANY
LENDER SHALL EVER RECEIVE ANYTHING OF VALUE WHICH IS CHARACTERIZED AS INTEREST
WITH RESPECT TO THE OBLIGATIONS OWED HEREUNDER OR UNDER APPLICABLE LAW AND
WHICH WOULD, APART FROM THIS PROVISION, BE IN EXCESS OF THE MAXIMUM LAWFUL
AMOUNT, AN AMOUNT EQUAL TO THE AMOUNT WHICH WOULD HAVE BEEN EXCESSIVE INTEREST
SHALL, WITHOUT PENALTY, BE APPLIED TO THE REDUCTION OF THE COMPONENT OF
PAYMENTS DEEMED TO BE PRINCIPAL AND NOT TO THE PAYMENT OF INTEREST, OR REFUNDED
TO THE BORROWER OR ANY OTHER





                                       26

<PAGE>   30
PAYOR THEREOF, IF AND TO THE EXTENT SUCH AMOUNT WHICH WOULD HAVE BEEN EXCESSIVE
EXCEEDS THE COMPONENT OF PAYMENTS DEEMED TO BE PRINCIPAL.  THE RIGHT TO DEMAND
PAYMENT OF ANY AMOUNTS EVIDENCED BY ANY OF THE OPERATIVE AGREEMENTS DOES NOT
INCLUDE THE RIGHT TO RECEIVE ANY INTEREST WHICH HAS NOT OTHERWISE ACCRUED ON
THE DATE OF SUCH DEMAND, AND NEITHER THE AGENT NOR ANY LENDER INTENDS TO CHARGE
OR RECEIVE ANY UNEARNED INTEREST IN THE EVENT OF SUCH DEMAND.  ALL INTEREST
PAID OR AGREED TO BE PAID TO THE AGENT OR ANY LENDER SHALL, TO THE EXTENT
PERMITTED BY APPLICABLE LAW, BE AMORTIZED, PRORATED, ALLOCATED, AND SPREAD
THROUGHOUT THE FULL STATED TERM (INCLUDING WITHOUT LIMITATION ANY RENEWAL OR
EXTENSION) OF THIS AGREEMENT SO THAT THE AMOUNT OF INTEREST ON ACCOUNT OF SUCH
PAYMENTS DOES NOT EXCEED THE MAXIMUM NONUSURIOUS AMOUNT PERMITTED BY APPLICABLE
LAW.
