<PAGE>

  (b) Conversions and Continuations.  In order to elect to Convert or continue
      -----------------------------                                           
Advances comprising part of the same Borrowing under this Section, the Borrower
shall deliver an irrevocable Notice of Conversion or Continuation to the
Administrative Agent at the  Administrative Agent's office no later than 11:00
a.m. (Dallas, Texas time) at least three Business Days in advance of the
proposed Conversion or continuation date.  Each such Notice of Conversion or
Continuation shall be in writing or by telecopier, specifying (i) the requested
Conversion or continuation date (which shall be a Business Day), (ii) the
Borrowing amount and Type of the Advances to be Converted or continued, (iii)

the  Administrative Agent shall provide each Bank with a copy thereof and, in
the case of a Conversion to or a continuation of LIBOR Rate Advances, notify
each Bank of the applicable interest rate under Section 2.06(b).  For purposes
other than the conditions set forth in Section 3.02, the portion of Advances
comprising part of the same Borrowing that are Converted to Advances of another
Type shall constitute a new Borrowing.  If the Borrower shall fail to specify an
Interest Period for a LIBOR Rate Advance including the continuation of a LIBOR
Rate Advance, the Borrower shall be deemed to have selected a Prime Rate
Advance.

  (c) Certain Limitations.  Notwithstanding anything in paragraphs (a) and (b)
      -------------------                                                     
above:

     (ii) except for Borrowings for the acquisition of  Future Properties by
  the Borrower or a Permitted New Subsidiary, (A) the Borrower may not request
  Borrowings on more than two days in any calendar month, and (B) the Borrower

  payment of Capital Expenditures and FF&E and any such request shall be made
  contemporaneously with any request to withdraw funds from the CAPEX Reserve

                                     -41-
<PAGE>
 
  as set forth in Section 5.07 in such month and shall be accompanied by the

     (iii)     at no time shall there be more than three Interest Periods
  applicable to outstanding LIBOR Rate Advances;

     (iv) the Borrower may not select LIBOR Rate Advances for any Borrowing to
  be made, Converted or continued if a Default has occurred and is continuing;

     (v) if any Bank shall, at any time prior to the making of any requested
  Borrowing comprised of LIBOR Rate Advances, notify the Administrative Agent
  that the introduction of or any change in or in the interpretation of any law
  or regulation makes it unlawful, or that any central bank or other
  governmental authority asserts that it is unlawful, for such Bank or its LIBOR
  Lending Office to perform its obligations under this Agreement to make LIBOR
  Rate Advances or to fund or maintain LIBOR Rate Advances, then such Bank's Pro
  Rata Share of such Borrowing shall be made as a Prime Rate Advance, provided
  that such Prime Rate Advance shall be considered part of the same Borrowing
  and interest on such Prime Rate Advance shall be due and payable at the same
  time that interest on the LIBOR Rate Advances comprising the remainder of such
  Borrowing shall be due and payable; and such Bank agrees to use commercially
  reasonable efforts (consistent with its internal policies and legal and
  regulatory restrictions) to designate a different Applicable Lending Office if
  the making of such designation would avoid the effect of this paragraph and
  would not, in the reasonable judgment of such Bank, be otherwise materially
  disadvantageous to such Bank;

     (vi) if the Administrative Agent is unable to determine the LIBOR Rate for
  LIBOR Rate Advances comprising any requested Borrowing, the right of the
  Borrower to select LIBOR Rate Advances for such Borrowing or for any
  subsequent Borrowing shall be suspended until the Administrative Agent shall
  notify the Borrower and the Banks that the circumstances causing such
  suspension no longer exist, and each Advance comprising such Borrowing shall
  be a Prime Rate Advance;

     (vii)     if the Majority Banks shall, at least one Business Day before the
  date of any requested Borrowing, notify the Administrative Agent that the
  LIBOR Rate for LIBOR Rate Advances comprising such Borrowing will not
  adequately reflect the cost to such Banks of making or funding their
  respective LIBOR Rate Advances, as the case may be, for such

                                     -42-
<PAGE>
 
  Borrowing, the right of the Borrower to select LIBOR Rate Advances for such
  Borrowing or for any subsequent Borrowing shall be suspended until the
  Administrative Agent shall notify the Borrower and the Banks that the
  circumstances causing such suspension no longer exist, and each Advance
  comprising such Borrowing shall be a Prime Rate Advance; and

     (viii)    if the Borrower shall fail to select the duration or continuation
  of any Interest Period for any LIBOR Rate Advances in accordance with the
  provisions contained in the definition of "Interest Period" in Section 1.01
  and paragraph (a) or (b) above, the Administrative Agent will forthwith so
  notify the Borrower and the Banks and such Advances will be made available to
  the Borrower on the date of such Borrowing as Prime Rate Advances or, if an
  existing Advance, Converted into Prime Rate Advances.

  (d) Notices Irrevocable.  Each Notice of Borrowing and Notice of Conversion or
      -------------------                                                       
Continuation shall be irrevocable and binding on the Borrower.  In the case of
any Borrowing which the related Notice of Borrowing specifies is to be comprised
of LIBOR Rate Advances, the Borrower shall indemnify each Bank against any loss,
out-of-pocket cost or expense incurred by such Bank as a result of any condition
precedent for Borrowing set forth in Article III not being satisfied for any
reason, including, without limitation, any loss, cost or expense actually
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Bank to fund the Advance to be made by such Bank as part of
such Borrowing when such Advance, as a result of such failure, is not made on
such date.

  (e) Administrative Agent Reliance.  Unless the Administrative Agent shall have
      -----------------------------                                             
received notice from a Bank before the date of any Borrowing that such Bank will
not make available to the Administrative Agent such Bank's Pro Rata Share of the
Borrowing, the Administrative Agent may assume that such Bank has made its Pro
Rata Share of such Borrowing available to the Administrative Agent on the date
of such Borrowing in accordance with paragraph (a) of this Section 2.02 and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount.  If and to the extent that
such Bank shall not have so made its Pro Rata Share of such Borrowing available
to the Administrative Agent, such Bank and the Borrower severally agree to
immediately repay to the Administrative Agent on demand such corresponding
amount, together with interest on such amount, for each day from the date such
amount is made available to the Borrower until the date such amount is repaid to
the Administrative Agent, at (i) in the case of the Borrower, the interest rate
applicable on each such day to Advances comprising such Borrowing and (ii) in
the case of such Bank, the Federal Funds Rate for each such

                                     -43-
<PAGE>
 
day.  If such Bank shall repay to the Administrative Agent such corresponding
amount and interest as provided above, such corresponding amount so repaid shall
constitute such Bank's Advance as part of such Borrowing for purposes of this
Agreement even though not made on the same day as the other Advances comprising
such Borrowing.

  (f) Bank Obligations Several.  The failure of any Bank to make the Advance to
      ------------------------                                                 
be made by it as part of any Borrowing shall not relieve any other Bank of its
obligation, if any, to make its Advance on the date of such Borrowing.  No Bank
shall be responsible for the failure of any other Bank to make the Advance to be
made by such other Bank on the date of any Borrowing.

  (g) Notes.  The indebtedness of the Borrower to each Bank resulting from
      -----                                                               
Advances owing to such Bank shall be evidenced by the Note of the Borrower
payable to the order of such Bank in substantially the form of Exhibit A.

                ---- 

  (a) Commitment Fees.   For the period from the Effective Date until the

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

  (a) Change of Control.  Upon the occurrence of any of the following:
      -----------------                                               

          (i) a change in control is reported by the Borrower, the Parent, AGH
       Leasing or any other Participating Lessee which is an Affiliate of the
       Borrower, or AGHI in response to either Item 6(e) of Schedule 14A of
       Regulation 14A promulgated under the Securities Exchange Act of 1934 (the
       "Exchange Act"), or

          (ii) any "person" (as such term is used in Section 13(d) and Section
       14(d)(2) of the Exchange Act) is or becomes the "beneficial owner" (as
       defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
       securities of the Borrower, the Parent, AGH Leasing or any other
       Participating Lessee which is an Affiliate of the Borrower, or AGHI
       representing the Control Percentage or more of the combined voting power
       of the Borrower's, the Parent's, such Participating Lessee's or the
       Manager's, as applicable, then outstanding securities;

then, in such event the Majority Banks may, at their sole option upon written
notice to the Borrower (a "Termination Notice"), declare the obligation of each
Bank to make Advances and the obligation of the Issuing Bank to issue, increase,
or extend Letters of Credit to be terminated, whereupon the same shall forthwith
terminate and the Commitments shall reduce to zero.

  Notwithstanding the foregoing, a "change of control" shall not be deemed to
occur as a result of the acquisition of securities of the Borrower, the Parent,
AGH Leasing or any other Participating Lessee which is an Affiliate of the
Borrower or AGHI by any of Steven D. Jorns, Bruce G. Wiles, Kenneth E. Barr,
James E. Sowell, Louis W. Shaw, II, Kenneth W. Shaw or their respective
Associates (as such term is defined in Rule 12b-2 promulgated under the Exchange
Act) or controlled Affiliates.

Advance on the Initial Maturity Date; provided that if the Maturity Date is
extended as provided in Section 2.01(b), the total outstanding balance of all

quarterly installments on August 1, 1999, November 1, 1999, February 1, 2000 and
May 1, 2000 in an amount equal to the product of (i) one sixtieth (1/60) times

amount of the Letter of Credit Exposure on the Initial Maturity Date. The
Borrower shall on the Maturity Date repay the outstanding principal amount of

  Section 2.06  Interest, Late Payment Fee.  The Borrower shall pay interest on
                --------------------------                                     
the unpaid principal amount of each Advance made by each Bank from the date of
such Advance until such principal amount shall be paid in full, at the following
rates per annum:

  (a) Prime Rate Advances.  If such Advance is a Prime Rate Advance, a rate per
      -------------------                                                      
annum (computed on the actual number of days elapsed, including the first day
and excluding the last, based on a 365 day year) equal at all times to the
lesser of (i) the Adjusted Prime Rate in effect from time to time plus the
                                                                  ----    
Applicable Margin and (ii) the Maximum Rate, payable in arrears on the last
Business Day of each calendar month and on the date such Prime Rate Advance
shall be paid in full, provided that during the continuance of an Event of
                       --------                                           
Default, Prime Rate Advances shall bear interest at a rate per annum equal at
all times to the lesser of (i) the rate required to be paid on such Advance
immediately prior to the date on which such amount becomes due plus three
                                                               ----      
percent (3%) and (ii) the Maximum Rate.

  (b) LIBOR Rate Advances.  If such Advance is a LIBOR Rate Advance, a rate per
      -------------------                                                      
annum (computed on the actual number of days elapsed, including the first day
and excluding the last, based on a 360 day year) equal at all times during the
Interest Period for such Advance to the lesser of (i) the LIBOR Rate for such
Interest Period plus the Applicable Margin and (ii) the Maximum Rate, payable in
                ----                                                            
arrears on the last day of each calendar month and the last day of such Interest
Period, and on the date such LIBOR Rate Advance shall be paid in full; provided
                                                                       --------
that during the continuance of an Event of Default, LIBOR Rate Advances shall
bear interest at a rate per annum equal at all times

                                     -46-
<PAGE>
 
to the lesser of the rate required to be paid on such Advance immediately
prior to the date on which such amount became due plus three percent (3%) and
                                                  ----                       
(ii) the Maximum Rate.

  (c) Usury Recapture.  In the event the rate of interest chargeable under this
      ---------------                                                          
Agreement or the Notes at any time is greater than the Maximum Rate, the unpaid
principal amount of the Notes shall bear interest at the Maximum Rate until the
total amount of interest paid or accrued on the Notes equals the amount of
interest which would have been paid or accrued on the Notes if the stated rates
of interest set forth in this Agreement had at all times been in effect.  In the
event, upon payment in full of the Notes, the total amount of interest paid or
accrued under the terms of this Agreement and the Notes is less than the total
amount of interest which would have been paid or accrued if the rates of
interest set forth in this Agreement had, at all times, been in effect, then the
Borrower shall, to the extent permitted by applicable law, pay the
Administrative Agent for the account of the Banks an amount equal to the
difference between (i) the lesser of (A) the amount of interest which would have
been charged on the Notes if the Maximum Rate had, at all times, been in effect
and (B) the amount of interest which would have accrued on the Notes if the
rates of interest set forth in this Agreement had at all times been in effect
and (ii) the amount of interest actually paid or accrued under this Agreement on
the Notes.  In the event the Banks ever receive, collect or apply as interest
any sum in excess of the Maximum Rate, such excess amount shall, to the extent
permitted by law, be applied to the reduction of the principal balance of the
Notes, and if no such principal is then outstanding, such excess or part thereof
remaining shall be paid to the Borrower.

  (d) Other Amounts Overdue.  If any amount payable under this Agreement other
      ---------------------                                                   
than the Advances is not paid when due and payable, including without
limitation, accrued interest and fees, then such overdue amount shall accrue
interest hereon due and payable on demand at a rate per annum equal to the
Adjusted Prime Rate plus three percent (3%), from the date such amount became
                    ----                                                     
due until the date such amount is paid in full.

  (e) Late Payment Fee.  Subject to the provisions of Section 9.12, if any
      ----------------                                                    
interest payable under this Agreement is not paid when due and payable (after
taking into account any applicable grace period), then the Borrower will pay to
the Banks contemporaneously with the payment of such past due interest a late
payment fee equal to an amount equal to the product of (i) such overdue interest
times (ii) four percent (4%).

Advances, at least one Business Day's prior written notice to the Administrative
Agent stating the proposed date and aggregate principal amount of such
prepayment, and if applicable, the relevant Interest Period for the Advances to
be prepaid.  If any such notice is given, the Borrower shall prepay Advances
comprising part of the same Borrowing in whole or ratably in part in an
aggregate principal amount equal to the amount specified in such notice, and
shall also pay accrued interest to the date of such prepayment on the principal
amount prepaid and amounts, if any, required to be paid pursuant to Section 2.08
as a result of such prepayment being made on such date; provided, however, that
                                                        --------  -------

  amount equal to the Letter of Credit Exposure.

     (ii) Borrowing Base Deficiency.  On each Borrowing Base Determination Date,
          -------------------------                                             
  the Borrower shall be required to prepay Advances in an aggregate amount equal
  to the excess of (A) the aggregate amount of outstanding Advances and Letter
  of Credit Exposure on such date over (B) the Borrowing Base, as determined on
  such Borrowing Base Determination Date (or, upon payment in full of all
  outstanding Advances, to deposit with the Administrative Agent into the Cash
  Collateral Account an amount equal to the amount of the Letter of Credit
  Exposure which exceeds the Borrowing Base).

     (iii) Asset Sale. Contemporaneously with the occurrence of any Asset
           ----------                                                    
  Sale, the Borrower shall prepay Advances in an amount equal to the Release
  Amount of each such Asset

  Collateral Release for a sale of a Permitted Non-Eligible Property).

     (iv) Capitalization Event.  Upon the occurrence of any Capitalization
          --------------------                                            
  Event, the Borrower shall prepay Advances in an amount equal to 100% of the
  Net Cash Proceeds of such Capitalization Event on the Business Day such Net
  Cash Proceeds are received by the Borrower or the Parent, as applicable (or,
  in connection with a Borrower Capitalization Event only, upon payment in full
  of all outstanding Advances, to deposit with the Administrative Agent into the
  Cash Collateral Account an amount equal to the lesser of the amount of the
  Letter of Credit Exposure or the remaining Net Cash Proceeds).

     (v) Accrued Interest.  Each prepayment pursuant to this Section 2.07(c)
         ----------------                                                   
  shall be accompanied by accrued interest on the amount prepaid to the date of
  such prepayment and amounts, if any, required to be paid pursuant to Section
  2.08 as a result of such prepayment being made on such date.

     (vi) Avoidance of Breakage Costs.  In the event that the amount of any
          ---------------------------                                      
  mandatory prepayment of Advances under this Section 2.07(c) exceeds the
  aggregate principal amount of Advances which consist of Prime Rate Advances
  (the amount of such excess being the "Excess Amount"), the Borrower shall have
                                        -------------                           
  the right, in lieu of making such prepayment in full, to prepay such
  outstanding Advances which are Prime Rate Advances and to deposit an amount
  equal to the Excess Amount with the Administrative Agent in the Cash
  Collateral Account maintained by and in the sole dominion and control of the
  Administrative Agent for the ratable benefit of the Banks.  Any amount so
  deposited shall be held by the Administrative Agent as collateral for the
  Obligations and applied to the prepayment of Advances which are LIBOR Rate
  Advances at the end of the current Interest Period(s) applicable thereto.  On
  any day on which amounts collected in the Cash Collateral Account remain on
  deposit in or to the credit of the Cash Collateral Account after giving effect
  to the payment made on such day pursuant to this Section 2.07(c), and the
  Borrower shall have delivered to the Administrative Agent a written request or
  a telephonic request (which shall be promptly confirmed in writing) prior to
  11:00 am (Dallas, Texas time) that such remaining collected amounts be
  invested in cash equivalents specified in such request, the Administrative
  Agent shall invest such funds, to the extent the Administrative Agent is
  reasonably able to do so, in such cash equivalents as are acceptable to, and
  with no risk to, the Administrative Agent on an overnight basis or with
  maturities such that amounts will be available to pay the Obligations secured
  thereby as they become due, whether

                                     -49-
<PAGE>
 
  at maturity, by acceleration or otherwise; provided, however, that any loss
                                             --------  -------               
  resulting from such investments shall be charged to and be immediately payable
  by the Borrower on demand by the Administrative Agent.

  (d) Ratable Payments.  Each payment of any Advance pursuant to this Section
      -----------------                                                      
2.07 or any other provision of this Agreement shall be made in a manner such
that all Advances comprising part of the same Borrowing are paid in whole or
ratably in part.

  (e) Effect of Notice.  All notices given pursuant to this Section 2.07 shall
      ----------------                                                        
be irrevocable and binding upon the Borrower.

  (f) Payments with respect to Hotel Property Limitations.  Notwithstanding
      ----------------------------------------------------                 
anything in this Agreement or any other Credit Document to the contrary, each
payment of any Advance pursuant to this Section 2.07 or any other provision of
this Agreement shall be made in a manner such that all Advances secured by a
Hotel Property for which any of the Security Documents for such Hotel Property
state that the amount of the Obligations secured by such Hotel Property is
limited in some way shall be deemed the last Advances repaid and, to the extent
that the Advances are repaid to an amount less than the amount of any such
limitation, shall be deemed the first Advances made to the Borrower if and when
the Borrower requests any further Advances.

  Section 2.08  Breakage Costs.  If (a) any payment of principal of any LIBOR
                --------------                                               
Rate Advance is made other than on the last day of the Interest Period for such
Advance as a result of any payment pursuant to Section 2.07 or the acceleration
of the maturity of the Notes pursuant to Article VIII or otherwise; (b) any
Conversion of a LIBOR Rate Advance is made other than on the last day of the
Interest Period for such Advance pursuant to Section 2.12 or otherwise; or (c)
the Borrower fails to make a principal or interest payment with respect to any
LIBOR Rate Advance on the date such payment is due and payable, the Borrower
shall, within 10 days of any written demand sent by any Bank to the Borrower
through the Administrative Agent, pay to the Administrative Agent for the
account of such Bank any amounts (without duplication of any other amounts
payable in respect of breakage costs) required to compensate such Bank for any
additional losses, out-of-pocket costs or expenses which it may reasonably incur
as a result of such payment or nonpayment, including, without limitation, any
loss (including loss of anticipated profits), cost or expense incurred by reason
of the liquidation or reemployment of deposits or other funds acquired by any
Bank to fund or maintain such Advance.

  Section 2.09  Increased Costs.
               --------------- 

  (a) LIBOR Rate Advances.  If, due to either (i) the introduction of or any
      -------------------                                                   
change (other than any change by way of imposition or increase of reserve
requirements included in the calculation of the LIBOR Rate) in or in the
interpretation of any law or regulation or (ii) the compliance with any
guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
cost to any Bank of agreeing to make or making, funding or maintaining LIBOR
Rate Advances, then the Borrower shall from time to time, upon demand by such
Bank (with a copy of such demand to the Administrative Agent), immediately pay
to the Administrative Agent for the account of such Bank additional amounts
(without duplication of any other amounts payable in respect of increased costs)
sufficient to compensate such Bank for such increased cost; provided, however,
                                                            --------  ------- 
that, before making any such demand, each Bank agrees to use commercially
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different Applicable Lending Office if the making
of such a designation would avoid the need for, or reduce the amount of, such
increased cost and would not, in the reasonable judgment of such Bank, be
otherwise disadvantageous to such Bank.  A certificate as to the amount of such
increased cost and detailing the calculation of such cost submitted to the
Borrower and the Administrative Agent by such Bank at the time such Bank demands
payment under this Section shall be conclusive and binding for all purposes,
absent manifest error.

  (b) Capital Adequacy.  If any Bank or the Issuing Bank determines in good
      ----------------                                                     
faith that compliance with any law or regulation or any guideline or request
from any central bank or other Governmental Authority (whether or not having the
force of law) implemented or effective after the date of this Agreement affects
or would affect the amount of capital required or expected to be maintained by
such Bank or the Issuing Bank and that the amount of such capital is increased
by or based upon the existence of such Bank's commitment to lend or the Issuing
Bank's commitment to issue Letters of Credit or any Bank's commitment to risk
participate in Letters of Credit and other commitments of this type, then, upon
30 days prior written notice by such Bank or the Issuing Bank (with a copy of
any such demand to the Administrative Agent), the Borrower shall immediately pay
to the Administrative Agent for the account of such Bank or to the Issuing Bank,
as the case may be, from time to time as specified by such Bank or the Issuing
Bank, additional amounts (without duplication of any other amounts payable in
respect of increased costs) sufficient to compensate such Bank or the Issuing
Bank, in light of such circumstances, (i) with respect to such Bank, to the
extent that the Issuing Bank reasonably determines such increase in capital to
be allocable to the existence of such Bank's commitment to lend under this
Agreement or its commitment to risk participate in

                                     -51-
<PAGE>
 
Letters of Credit and (ii) with respect to the Issuing Bank, to the extent that
such Issuing Bank reasonably determines such increase in capital to be allocable
to the issuance or maintenance of the Letters of Credit.  A certificate as to
such amounts and detailing the calculation of such amounts submitted to the
Borrower and the Administrative Agent by such Bank or the Issuing Bank shall be
conclusive and binding for all purposes, absent manifest error.

  (c) Letters of Credit.  If any change in any law or regulation or in the
      -----------------                                                   
interpretation thereof by any court or administrative or Governmental Authority
charged with the administration thereof shall either (i) impose, modify, or deem
applicable any reserve, special deposit, or similar requirement against letters
of credit issued by, or assets held by, or deposits in or for the account of,
Issuing Bank or any Bank or (ii) impose on Issuing Bank or any Bank any other
condition regarding the provisions of this Agreement relating to the Letters of
Credit or any Letter of Credit Obligations, and the result of any event referred
to in the preceding clause (i) or (ii) shall be to increase the cost to Issuing
Bank of issuing or maintaining any Letter of Credit, or increase the cost to
such Bank of its risk participation in any Letter of Credit (which increase in
cost shall be determined by Issuing Bank's or such Bank's reasonable allocation
of the aggregate of such cost increases resulting from such event), then, upon
demand by Issuing Bank or such Bank (with a copy sent to the Administrative
Agent), as the case may be, the Borrower shall pay to the Administrative Agent
for the account of Issuing Bank or Bank, as the case may be, from time to time
as specified by Issuing Bank or such Bank, additional amounts which shall be
sufficient to compensate such Issuing Bank or such Bank for such increased cost.
Issuing Bank and each Bank agrees to use commercially reasonable efforts
(consistent with internal policy and legal and regulatory restrictions) to
designate a different Applicable Lending Office for the booking of its Letters
of Credit or risk participations if the making of such designation would avoid
the effect of this paragraph and would not, in the reasonable judgment of
Issuing Bank or such Bank, be otherwise disadvantageous to Issuing Bank or such
Bank, as the case may be.  A certificate as to such increased cost incurred by
Issuing Bank or such Bank, as the case may be, as a result of any event
mentioned in clause (i) or (ii) above, and detailing the calculation of such
increased costs submitted by Issuing Bank or such Bank to the Borrower and the
Administrative Agent, shall be conclusive and binding for all purposes, absent
manifest error.

  Section 2.10  Payments and Computations.
               ------------------------- 

  (a) Payment Procedures.  Except if otherwise set forth herein, the Borrower
      ------------------                                                     
shall make each payment under this Agreement and under the Notes not later than
11:00 a.m. (Dallas, Texas time)

                                     -52-
<PAGE>
 
on the day when due in Dollars to the Administrative Agent at the location
referred to in the Notes (or such other location as the Administrative Agent
shall designate in writing to the Borrower) in same day funds.  The
Administrative Agent will on the same day cause to be distributed like funds
relating to the payment of principal, interest or fees ratably (other than
amounts payable solely to the Administrative Agent, the Issuing Banks, or a
specific Bank pursuant to Section 2.03(b), 2.03(c), 2.06(c), 2.08, 2.09, 2.11,
2.12, or 2.13(c) but after taking into account payments effected pursuant to
Section 9.04) to the Banks in accordance with each Bank's Pro Rata Share for the
account of their respective Applicable Lending Offices, and like funds relating
to the payment of any other amount payable to any Bank or Issuing Bank for the
account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement.  The Borrower hereby authorizes the
Administrative Agent to instruct the Cash Manager following and during the
continuance of an Event of Default to withdraw from or offset against the
Borrower's and the Borrower's Subsidiaries accounts with the Cash Manager
(including the Borrower's Bank Accounts) in order to cause timely payment to be
made to the Administrative Agent of all principal, interest, fees and expenses
due hereunder or under the Notes or the other Credit Documents (subject to
sufficient funds being available in such accounts for that purpose).

  (b) Computations.  All computations of interest based on the Adjusted Prime
      ------------                                                           
Rate shall be made by the Administrative Agent on the basis of a year of 365
days and all computations of fees and interest based on the LIBOR Rate and the
Federal Funds Rate shall be made by the Administrative Agent on the basis of a
year of 360 days, in each case for the actual number of days (including the
first day, but excluding the last day) occurring in the period for which such
interest or fees are payable.  Each determination by the Administrative Agent of
an interest rate shall be conclusive and binding for all purposes, absent
manifest error.

  (c) Non-Business Day Payments.  Whenever any payment shall be stated to be due
      -------------------------                                                 
on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be;
                                                                               
provided, however, that if such extension would cause payment of interest on or
--------                                                                       
principal of LIBOR Rate Advances to be made in the next following calendar
month, such payment shall be made on the next preceding Business Day.

  (d) Administrative Agent Reliance.  Unless the Administrative Agent shall have
      -----------------------------                                             
received written notice from the Borrower prior to the date on which any payment
is due to the Banks that the Borrower will not make such payment in full, the
Administrative Agent may assume that the

                                     -53-
<PAGE>
 
Borrower has made such payment in full to the Administrative Agent on such date
and the Administrative Agent may, in reliance upon such assumption, cause to be
distributed to each Bank on such date an amount equal to the amount then due
such Bank.  If and to the extent the Borrower shall not have so made such
payment in full to the Administrative Agent, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank,
together with interest, for each day from the date such amount is distributed to
such Bank until the date such Bank repays such amount to the Administrative
Agent, at the Federal Funds Rate for each such day.

  (e) Application of Payments.  Unless otherwise specified in Section 2.07
      -----------------------                                             
hereof, whenever any payment received by the Administrative Agent under this
Agreement is insufficient to pay in full all amounts then due and payable under
this Agreement and the Notes, such payment shall be distributed and applied by
the Administrative Agent and the Banks in the following order:  first, to the
                                                                -----        
payment of fees and expenses due and payable to the Administrative Agent under
and in connection with this Agreement or any other Credit Document; second, to
                                                                    ------    
the payment of all expenses due and payable under Section 2.11(c), ratably among
the Banks in accordance with the aggregate amount of such payments owed to each
such Bank; third, to the payment of fees due and payable to the Issuing Bank
           -----                                                            
pursuant to Section 2.03(b); fourth, to the payment of all other fees due and
                             ------                                          
payable under Section 2.03 ratably among the Banks in accordance with their
applicable Commitments; and fifth, to the payment of the interest accrued on and
                            -----                                               
the principal amount of all of the Notes and the interest accrued on and all
Reimbursement Obligations, regardless of whether any such amount is then due and
payable, ratably among the Banks in accordance with the aggregate accrued
interest plus the aggregate principal amount owed to such Bank.

  (f) Register.  The Administrative Agent shall record in the Register the
      --------                                                            
Commitment and the Advances from time to time of each Bank and each repayment or
prepayment in respect to the principal amount of such Advances of each Bank.
Any such recordation shall be conclusive and binding on the Borrower and each
Bank, absent manifest error; provided however, that failure to make any such
                             -------- -------                               
recordation, or any error in such recordation, shall not affect the Borrower's
obligations hereunder in respect of such Advances.

  Section 2.11  Taxes.
               ----- 

  (a) No Deduction for Certain Taxes.  Any and all payments by the Borrower
      ------------------------------                                       
shall be made, in accordance with Section 2.10, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect


                                     -54-
<PAGE>
 
thereto, excluding, in the case of each Bank, Issuing Bank, and the
Administrative Agent, taxes imposed on its income, and franchise taxes imposed
on it, by the jurisdiction under the laws of which such Bank, Issuing Bank, or
the Administrative Agent (as the case may be) is organized or any political
subdivision of the jurisdiction (all such nonexcluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes") and, in the case of each Bank and Issuing Bank, Taxes by the
jurisdiction of such Bank's Applicable Lending Office or any political
subdivision of such jurisdiction.  If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable to any Bank, Issuing
Bank, or the Administrative Agent, (i) the sum payable shall be increased as may
be necessary so that, after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.11), such Bank,
Issuing Bank, or the Administrative Agent (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made;
                                                                                
provided, however, that if the Borrower's obligation to deduct or withhold Taxes
--------                                                                        
is caused solely by such Bank's, Issuing Bank's, or the Administrative Agent's
failure to provide the forms described in paragraph (e) of this Section 2.11 and
such Bank, Issuing Bank, or the Administrative Agent could have provided such
forms, no such increase shall be required; (ii) the Borrower shall make such
deductions; and (iii) the Borrower shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable
Legal Requirements.

  (b) Other Taxes.  In addition, the Borrower agrees to pay any present or
      -----------                                                         
future stamp or documentary taxes or any other excise or property taxes, charges
or similar levies which arise from any payment made or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, the
Notes, or the other Credit Documents (hereinafter referred to as "Other Taxes").

  (c) Indemnification.  The Borrower indemnifies each Bank, Issuing Bank, and
      ---------------                                                        
the Administrative Agent for the full amount of Taxes or Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed by any Governmental
Authority on amounts payable under this Section 2.11) paid by such Bank, Issuing
Bank, or the Administrative Agent (as the case may be) and any liability
(including interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted.
Each payment required to be made by the Borrower in respect of this
indemnification shall be made to the Administrative Agent for the benefit of any
party claiming such indemnification within 30 days from the date the Borrower
receives written demand detailing the calculation of such amounts therefor from
the Administrative Agent on behalf of itself as Administrative Agent, Issuing
Bank, or any such Bank.  If any Bank, the Administrative Agent, or Issuing Bank
receives a refund in respect of any Taxes or Other Taxes paid

                                     -55-
<PAGE>
 
by the Borrower under this paragraph (c), such Bank, the Administrative Agent,
or Issuing Bank, as the case may be, shall promptly pay to the Borrower the
Borrower's share of such refund.

  (d) Evidence of Tax Payments.  The Borrower will pay prior to delinquency all
      ------------------------                                                 
Taxes and other Taxes payable in respect of any payment.  Within 30 days after
the date of any payment of Taxes, the Borrower will furnish to the
Administrative Agent, at its address referred to in Section 9.02, the original
or a certified copy of a receipt evidencing payment of such Taxes or Other
Taxes.

  (e) Foreign Bank Withholding Exemption.  Each Bank and each Issuing Bank that
      ----------------------------------                                       
is not incorporated under the laws of the United States of America or a state
thereof agrees that it will deliver to the Borrower and the Administrative Agent
on the date of this Agreement or upon the effectiveness of any Assignment and
Acceptance (i) two duly completed copies of United States Internal Revenue
Service Form 1001 or 4224 or successor applicable form, as the case may be,
certifying in each case that such Bank is entitled to receive payments under
this Agreement and the Notes payable to it, without deduction or withholding of
any United States federal income taxes, (ii) if applicable, an Internal Revenue
Service Form W-8 or W-9 or successor applicable form, as the case may be, to
establish an exemption from United States backup withholding tax, and (iii) any
other governmental forms which are necessary or required under an applicable tax
treaty or otherwise by law to reduce or eliminate any withholding tax, which
have been reasonably requested by the Borrower.  Each Bank which delivers to the
Borrower and the Administrative Agent a Form 1001 or 4224 and Form W-8 or W-9
pursuant to the next preceding sentence further undertakes to deliver to the
Borrower and the Administrative Agent two further copies of Form 1001 or 4224
and Form W-8 or W-9, or successor applicable forms, or other manner of
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form previously delivered by it to the Borrower and
the Administrative Agent, and such extensions or renewals thereof as may
reasonably be requested by the Borrower and the Administrative Agent certifying
in the case of a Form 1001 or 4224 that such Bank is entitled to receive
payments under this Agreement without deduction or withholding of any United
States federal income taxes.  If an event (including without limitation any
change in treaty, law or regulation) has occurred prior to the date on which any
delivery required by the preceding sentence would otherwise be required which
renders all such forms inapplicable or which would prevent any Bank from duly
completing and delivering any such letter or form with respect to it and such
Bank advises the Borrower and the Administrative Agent that it is not capable of
receiving payments without any deduction or withholding of United States federal
income tax,

                                     -56-
<PAGE>
 
and in the case of a Form W-8 or W-9, establishing an exemption from United
States backup withholding tax, such Bank shall not be required to deliver such
forms.  The Borrower shall withhold tax at the rate and in the manner required
by the laws of the United States with respect to payments made to a Bank failing
to timely provide the requisite Internal Revenue Service forms.

  Section 2.12  Illegality.  If any Bank shall notify the Administrative Agent
               ----------                                                    
and the Borrower that the introduction of or any change in or in the
interpretation of any Legal Requirement makes it unlawful, or that any central
bank or other Governmental Authority asserts that it is unlawful for such Bank
or its LIBOR Lending Office to perform its obligations under this Agreement to
maintain any LIBOR Rate Advances of such Bank then outstanding hereunder, then,
notwithstanding anything herein to the contrary, the Borrower shall, if demanded
by such Bank by notice to the Borrower and the Administrative Agent no later
than 11:00 a.m. (Dallas, Texas time), (a) if not prohibited by Legal Requirement
to maintain such LIBOR Rate Advances for the duration of the Interest Period, on
the last day of the Interest Period for each outstanding LIBOR Rate Advance of
such Bank or (b) if prohibited by Legal Requirement to maintain such LIBOR Rate
Advances for the duration of the Interest Period, on the second Business Day
following its receipt of such notice from such Bank, Convert all LIBOR Rate
Advances of such Bank then outstanding to Prime Rate Advances, and pay accrued
interest on the principal amount Converted to the date of such Conversion and
amounts, if any, required to be paid pursuant to Section 2.08 as a result of
such Conversion being made on such date.  Each Bank agrees to use commercially
reasonable efforts (consistent with its internal policies and legal and
regulatory restrictions) to designate a different Applicable Lending Office if
the making of such designation would avoid the effect of this paragraph and
would not, in the reasonable judgment of such Bank, be otherwise disadvantageous
to such Bank.

  Section 2.13  Letters of Credit.
               ----------------- 

  (a) Issuance.  From time to time from the date of this Agreement until three
      --------                                                                
months before the Maturity Date, at the request of the Borrower, each Issuing
Bank shall, on any Business Day and on the terms and conditions hereinafter set
forth, issue, increase, decrease, amend, or extend the expiration date of
Letters of Credit for the account of the Borrower (for its own benefit or for
the benefit of any of its Subsidiaries).  No Letter of Credit will be issued,
increased, or extended (i) if such issuance, increase, or extension would cause
the Letter of Credit Exposure to exceed the lesser of (x) $20,000,000 or (y) an
amount equal to (A) the lesser of the Borrowing Base or the aggregate
Commitments less (B) the aggregate outstanding Advances and Letter of Credit
            ----                                                            
Exposure at such time; (ii) unless such Letter of Credit has an Expiration Date
not later than the earlier of (A) one year

                                     -57-
<PAGE>
 
after the date of issuance thereof and (B) one day prior to the Maturity Date;
(iii) unless such Letter of Credit is in form and substance acceptable to the
respective Issuing Bank; (iv) unless such Letter of Credit is a standby letter
of credit not supporting the repayment of indebtedness for borrowed money of any
Person; (v) unless the Borrower has delivered to the respective Issuing Bank the
completed and executed Letter of Credit Documents (other than the Letter of
Credit) on such Issuing Bank's standard form, which shall contain terms no more
restrictive than the terms of this Agreement; (vi) unless such Letter of Credit
is governed by the Uniform Customs and Practice for Documentary Credits (1993
Revision), International Chamber of Commerce Publication No. 500 ("UCP") or any
successor to the UCP.  After the Initial Maturity Date, the Borrower will no
longer have the right to any increase in the Letter of Credit Exposure; and
(vii) no Default has occurred and is continuing or would result from the
issuance of such Letter of Credit.  If the terms of any of the Letter of Credit
Documents referred to in the foregoing clause (v) conflicts with the terms of
this Agreement, the terms of this Agreement shall control.

  (b) Participations.  On the date of the issuance or increase of any Letter of
      --------------                                                           
Credit on or after the Effective Date, each Issuing Bank shall be deemed to have
sold to each other Bank and each other Bank shall have been deemed to have
purchased from such Issuing Bank a participation in the Letter of Credit
Exposure related to the Letters of Credit issued by such Issuing Bank equal to
such Bank's Pro Rata Share at such date and such sale and purchase shall
otherwise be in accordance with the terms of this Agreement.  Each Issuing Bank
shall promptly notify each such participant Bank by telex, telephone, or
telecopy of each Letter of Credit of such Issuing Bank issued, increased or
decreased, and the actual dollar amount of such Bank's participation in such
Letter of Credit.  Each Bank's obligation to purchase participating interests
pursuant to this Section and to reimburse the respective Issuing Bank for such
Bank's Pro Rata Share of any payment under a Letter of Credit by such Issuing
Bank not reimbursed in full by the Borrower shall be absolute and unconditional
and shall not be affected by any circumstance, including, without limitation,
(i) any of the circumstances described in paragraph (d) below, (ii) the
occurrence and continuance of a Default, (iii) an adverse change in the
financial condition of the Borrower or any Guarantor, or (iv) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing, except for any such circumstance, happening or event constituting
or arising from gross negligence or willful misconduct on the part of such
Issuing Bank.

  (c) Reimbursement.  The Borrower shall have the right (but not the obligation)
      -------------                                                             
to pay promptly on demand to each Issuing Bank in respect of each Letter of
Credit issued by such Issuing Bank an amount equal to any amount paid by such
Issuing Bank under or in respect of such Letter

                                     -58-
<PAGE>
 
of Credit.  In the event any Issuing Bank makes a payment pursuant to a request
for draw presented under a Letter of Credit and such payment is not promptly
reimbursed by the Borrower upon demand, such Issuing Bank shall give notice of
such payment to the Administrative Agent and the Banks, and each Bank shall
promptly reimburse such Issuing Bank for such Bank's Pro Rata Share of such
payment, and such reimbursement shall be deemed for all purposes of this
Agreement to constitute a Prime Rate Advance to the Borrower from such Bank.  If
such reimbursement is not made by any Bank to any Issuing Bank on the same day
on which such Issuing Bank shall have made payment on any such draw, such Bank
shall pay interest thereon to such Issuing Bank for each such day from the date
such payment should have been made until the date repaid at a rate per annum
equal to the Federal Funds Rate for each such day.  The Borrower hereby
unconditionally and irrevocably authorizes, empowers, and directs the
Administrative Agent and the Banks to record and otherwise treat each payment
under a Letter of Credit not immediately reimbursed by the Borrower as a
Borrowing comprised of Prime Rate Advances to the Borrower.

  (d) Obligations Unconditional.  The obligations of the Borrower under this
      -------------------------                                             
Agreement in respect of each Letter of Credit shall be unconditional and
irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, notwithstanding the following circumstances:

     (i)    any lack of validity or enforceability of any Letter of Credit
  Documents;

     (ii)   any amendment or waiver of or any consent to departure from any
  Letter of Credit Documents;

     (iii)  the existence of any claim, set-off, defense or other right which
  the Borrower or any Bank or any other Person may have at any time against any
  beneficiary or transferee of such Letter of Credit (or any Persons for whom
  any such beneficiary or any such transferee may be acting), the respective
  Issuing Bank or any other Person or entity, whether in connection with this
  Agreement, the transactions contemplated in this Agreement or in any Letter of
  Credit Documents or any unrelated transaction;

     (iv)   any statement or any other document presented under such 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 to
  the extent the respective Issuing Bank would not be liable therefor pursuant
  to the following paragraph (e);

                                     -59-
<PAGE>
 
     (v)   payment by the respective Issuing Bank under such Letter of Credit
  against presentation of a draft or certificate which does not comply with the
  terms of such Letter of Credit; or

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

  (e) Liability of Issuing Banks.  The Borrower assumes all risks of the acts or
      --------------------------                                                
omissions of any beneficiary or transferee of any Letter of Credit with respect
to its use of such Letter of Credit. No Issuing Bank, nor any other Bank, nor
any of their respective officers or directors shall be liable or responsible
for:

     (i)   the use which may be made of any Letter of Credit or any acts or
  omissions of any beneficiary or transferee in connection therewith;

     (ii)  the validity, sufficiency or genuineness of documents, or of any
  endorsement thereon, even if such documents should prove to be in any or all
  respects invalid, insufficient, fraudulent or forged;

     (iii) payment by such Issuing Bank against presentation of documents
  which do not comply with the terms of a Letter of Credit, including failure of
  any documents to bear any reference or adequate reference to the relevant
  Letter of Credit; or

     (iv)  any other circumstances whatsoever in making or failing to make
  payment under any Letter of Credit (including such Issuing Bank's own
  negligence),

except that the Borrower shall have a claim against such Issuing Bank, and such
------                                                                         
Issuing Bank shall be liable to, and shall promptly pay to, the Borrower, to the
extent of any direct, as opposed to consequential, damages suffered by the
Borrower which the Borrower proves were caused by (A) such Issuing Bank's
willful misconduct or gross negligence in determining whether documents
presented under a Letter of Credit comply with the terms of such Letter of
Credit or (B) such Issuing Bank's gross negligence in failing to make lawful

Obligations in excess of its Pro Rata Share of payments on account of the
Advances or Letter of Credit Obligations obtained by all the Banks, such Bank
shall notify the Administrative Agent and forthwith purchase from the other
Banks such participations in

be necessary to cause such purchasing Bank to share the excess payment ratably
in accordance with the requirements of this Agreement with each of them;
provided, however, that if all or any portion of such excess payment is
--------

Proceeds are collected:

     (i) The Borrower shall demonstrate to the Administrative Agent's reasonable
  satisfaction that the Proceeds, together with amounts deposited by the
  Borrower pursuant to subparagraph (ii) will be adequate to accomplish the

  and with a contractor, satisfactory to the Administrative Agent.

     (ii) To the extent that the Proceeds are insufficient in the reasonable
  determination of the Administrative Agent to accomplish the repairs and
  reconstruction required above, the Borrower shall deliver to the
  Administrative Agent funds (the "Shortfall Funds") in the amount of such
  shortfall, which funds shall be, at the Administrative Agent's option,
  assigned to the Administrative Agent as security for the Borrower's
  obligations hereunder and shall be maintained with the Administrative Agent
  and disbursed in the same manner as the Proceeds.

     (iii)     The Borrower shall execute such documents, in form and content
  satisfactory to the Administrative Agent, as the Administrative Agent requires
  to evidence and secure the Borrower's obligation to use all amounts disbursed
  for the prompt repair and reconstruction of the Hotel Property in accordance
  with the plans and specifications approved by the Administrative Agent.

     (iv) There shall have occurred no Default which is continuing or has not
  otherwise been cured or waived, and the Administrative Agent shall have
  received a certificate to that effect signed by a Responsible Officer of the
  Borrower.

  (b) Any Proceeds and Shortfall Funds to be disbursed to the Borrower shall be
held by the Administrative Agent and disbursed at such times and in such amounts
as the Administrative Agent shall reasonably deem necessary to fund the ongoing
repairs, provided the Administrative Agent is satisfied with such repairs.  The
Administrative Agent shall have no obligation to disburse proceeds more than
once per month.  Any amounts remaining undisbursed following completion of (and
full payment for) such repairs and reconstruction shall be returned to the
Borrower up to the amount of

                                      -97-
<PAGE>
 
any Shortfall Funds deposited by Borrower, and any other amounts remaining shall
be applied against the outstanding principal balance of and/or unpaid accrued
interest on, the Notes, in such order as the Administrative Agent chooses in its
sole discretion.

  (c) In the event the Borrower fails to fulfill the conditions set forth in
Sections 5.11(a)(i)-(iv) within 90 days following the date on which the damage

such order as the Administrative Agent chooses in its sole discretion.

  (d) The Borrower hereby assigns to the Administrative Agent, as security for
the Borrower's obligations under the Credit Documents, all compensation, awards
and other amounts payable to the Borrower in connection with any taking of any
portion of a Hotel Property for public use, and any proceeds of any related
settlement regardless of whether eminent domain proceedings are instituted in
connection therewith (collectively, "Compensation").  The Borrower shall deliver
all Compen  sation to the Administrative Agent immediately upon receipt.  If

discretion, any Compensation received by the Administrative Agent shall be (i)
disbursed to Borrower for repairs and reconstruction; and/or (ii) paid to
Borrower; and/or (iii) applied against the outstanding principal balance of
and/or unpaid accrued interest on, the Notes in such order as the Administrative
Agent chooses in its sole discretion; all in accordance with the rights,

all such Letters of Credit.  After any retiring Agent's or Issuing Bank's
resignation or removal hereunder as Documentation Agent, Administrative Agent or
Issuing Bank, the provisions of this Article VIII shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was such Agent or
Issuing Bank under this Agreement and the other Credit Documents.

(as such term is defined in Chapter One) from time to time in effect.

  Section 9.12  Usury Not Intended.  It is the intent of the Borrower and each
                ------------------                                            
Bank in the execution and performance of this Agreement and the other Credit
Documents to contract in strict compliance with applicable usury laws, including
conflicts of law concepts, governing the Advances of each Bank including such
applicable laws of the State of Texas and the United States of America from time
to time in effect.  In furtherance thereof, the Banks and the Borrower stipulate
and agree that none of the terms and provisions contained in this Agreement or
the other Credit Documents shall ever be construed to create a contract to pay,
as consideration for the use, forbearance or detention of money, interest at a
rate in excess of the Maximum Rate and that for purposes hereof "interest" shall
include the aggregate of all charges which constitute interest under such laws
that are contracted for, charged or received under this Agreement; and in the
event that, notwithstanding the

                                     -130-
<PAGE>
 
foregoing, under any circumstances the aggregate amounts taken, reserved,
charged, received or paid on the Advances, include amounts which by applicable
law are deemed interest which would exceed the Maximum Rate, then such excess
shall be deemed to be a mistake and each Bank receiving same shall credit the
same on the principal of its Notes (or if such Notes shall have been paid in
full, refund said excess to the Borrower).  In the event that the maturity of
the Notes is accelerated by reason of any election of the holder thereof
resulting from any Event of Default under this Agreement or otherwise, or in the
event of any required or permitted prepayment, then such consideration that
constitutes interest may never include more than the Maximum Rate and excess
interest, if any, provided for in this Agreement or otherwise shall be canceled
automatically as of the date of such acceleration or prepayment and, if
theretofore paid, shall be credited on the applicable Notes (or, if the
applicable Notes shall have been paid in full, refunded to the Borrower). The
provisions of this Section shall control over all other provisions of this
Agreement or the other Credit Documents which may be in apparent conflict
herewith.

into any agreements pertaining to the joint use of facilities, such agreements
will be subject to the reasonable approval of the Documentation Agent.

Borrower at its address specified in Section 9.02.  The Borrower agrees that a

provided by law.  Nothing in this Section shall affect the rights of any Bank,
the Documentation Agent, or the Administrative Agent to serve legal process in
any other manner permitted by the law or affect the right of any Bank, the
Documentation Agent or the Administrative Agent to bring any action or
proceeding against the Borrower or its Property in the courts of any other

the rights or power to exercise control over the affairs and/or management of
the Borrower, any of its Subsidiaries or any Guarantor, the power of the Banks
being limited to the right to exercise the remedies provided in the Credit
Documents; provided, however, that if any Bank becomes the owner of any stock,
or other equity interest in, any Person whether through foreclosure or
otherwise, such Bank shall be entitled (subject to requirements of law) to
exercise such legal rights as it may have by being owner of such stock, or other
equity interest in, such Person.
