     Administrative  Agent in  connection  with the  issuance  of each Letter of
     Credit and/or any amendment or  modification  of any nature to any existing

     Exposure  of all  Banks  shall be due and  payable  without  any  notice to
     Borrower or any other act by Administrative  Agent or any Bank. Any amounts
     so deposited shall be held by Administrative  Agent for the ratable benefit
     of all Banks as security for the outstanding  Letter of Credit Exposure and
     the other Obligations,  and Borrower will, in connection therewith, execute
     and deliver such security agreements in form and substance  satisfactory to
     Administrative  Agent which  Administrative  Agent may, in its  discretion,
     require. As drafts or demands for payment are presented under any Letter of
     Credit,  Administrative  Agent shall apply such cash to satisfy such drafts
     or demands.  When all Letters of Credit  have  expired and the  Obligations
     have been repaid in full (and no Bank has any  obligation  to lend or issue
     Letters of Credit hereunder) or such Event of Default has been cured to the
     satisfaction  of Required  Banks,  Administrative  Agent  shall  release to
     Borrower any remaining cash deposited under this Section  3.1(b).  Whenever
     Borrower is required to make deposits  under this Section  3.1(b) and fails
     to do so on the day such deposit is due,  Administrative  Agent or any Bank
     may, without notice to Borrower,  make such deposit (whether by application
     of proceeds of any collateral for the Obligations,  by transfers from other
     accounts  maintained  with any Bank or  otherwise)  using  any  funds  then
     available to any Bank of any Credit Party, any guarantor or any other party
     liable for repayment of the Obligations.

          Notwithstanding  anything to the contrary  contained herein,  Borrower
     hereby agrees to reimburse  each Letter of Credit Issuer  immediately  upon
     demand by such Letter of Credit Issuer, and in immediately available funds,
     for any payment or disbursement  made by such Letter of Credit Issuer under
     any Letter of Credit  issued by it.  Payment shall be made by Borrower with
     interest on the amount so paid or disbursed by Letter of Credit Issuer from
     and  including  the date  payment is made under any Letter of Credit to and
     including  the date of  payment,  at the lesser of (i) the  Maximum  Lawful
     Rate,  or (ii) the Default Rate.  The  obligations  of Borrower  under this
     paragraph  will  continue  until all Letters of Credit have expired and all
     reimbursement  obligations  with respect  thereto have been paid in full by
     Borrower and until all other Obligations shall have been paid in full.

                                                                              25




          Borrower shall be obligated to reimburse  Letter of Credit Issuer upon
     demand for all  amounts  paid  under  Letters of Credit as set forth in the
     immediately preceding paragraph hereof; provided,  however, if Borrower for
     any reason fails to reimburse  Letter of Credit Issuer in full upon demand,
     Banks  shall  reimburse  Letter of Credit  Issuer in  accordance  with each
     Banks'  Commitment  Percentage  for amounts due and unpaid from Borrower as
     set forth hereinbelow;  provided,  however, that no such reimbursement made
     by Banks shall  discharge  Borrower's  obligations  to reimburse  Letter of
     Credit Issuer.  All  reimbursement  amounts  payable by any Bank under this
     Section  3.1(b) shall include  interest  thereon at the Federal Funds Rate,
     from the date of the payment of such amounts by Letter of Credit  Issuer to
     the date of  reimbursement  by such  Bank.  No Bank shall be liable for the
     performance or  nonperformance  of the  obligations of any other Bank under
     this paragraph. The reimbursement obligations of Banks under this paragraph
     shall continue after the Termination Date and shall survive  termination of
     this Agreement and the other Loan Papers.

          Borrower  shall  indemnify and hold  Administrative  Agent,  Letter of
     Credit  Issuer and each Bank,  and their  respective  officers,  directors,
     representatives  and employees harmless from loss for any claim,  demand or
     liability which may be asserted  against any or such  indemnified  party in
     connection  with  actions  taken under  Letters of Credit or in  connection
     therewith  (including  losses  resulting from the negligence of any or such
     indemnified  party),  and shall pay each  indemnified  party for reasonable
     fees of  attorneys  and legal costs paid or  incurred  by each  indemnified
     party in connection  with any matter  related to Letters of Credit,  except
     for  losses  and  liabilities  incurred  as a direct  result  of the  gross
     negligence or willful  misconduct of such  indemnified  party, IT BEING THE
     EXPRESS  INTENTION  OF THE  PARTIES  THAT EACH  INDEMNIFIED  PARTY SHALL BE
     INDEMNIFIED  FOR  THE  CONSEQUENCES  OF ITS  OWN  ORDINARY  NEGLIGENCE.  If
     Borrower for any reason fails to indemnify or pay such indemnified party as
     set forth herein in full,  Banks shall  indemnify and pay such  indemnified
     party upon demand, in accordance with each Bank's Commitment  Percentage of
     such amounts due and unpaid from Borrower; provided, however, that, no such
     payment made by Banks shall discharge Borrower's obligation to indemnify or
     pay  such  indemnified  party in  accordance  with the  terms  hereof.  The
     provisions  of  this  paragraph  shall  survive  the  termination  of  this
     Agreement.

          Neither  Administrative  Agent nor any other  Letter of Credit  Issuer
     makes any representation or warranty,  nor assumes any responsibility  with
     respect to the validity,  legality,  sufficiency or  enforceability  of any
     letter of credit application  executed and delivered in connection with any
     Letter of Credit issued  hereunder or any document  relative  thereto or to
     the collectibility  thereunder.  Neither Administrative Agent nor any other
     Letter  of Credit  Issuer  assumes  any  responsibility  for the  financial
     condition of Borrower or for the performance of any obligation of Borrower.
     Administrative  Agent and each  other  Letter of Credit  Issuer may use its
     discretion  with respect to exercising or refraining  from  exercising  any
     rights,  or taking or refraining from taking any action which may be vested
     in it or which it may be  entitled  to take or assert  with  respect to any
     Letter of Credit or any letter of credit application.  FURTHERMORE,  EXCEPT
     AS SET FORTH HEREIN,  NEITHER  ADMINISTRATIVE AGENT NOR ANY OTHER LETTER OF
     CREDIT  ISSUER SHALL BE UNDER ANY  LIABILITY  TO ANY BANK,  WITH RESPECT TO
     ANYTHING ADMINISTRATIVE AGENT OR ANY SUCH LETTER OF CREDIT ISSUER MAY DO OR
     REFRAIN FROM DOING IN THE EXERCISE OF ITS JUDGMENT,  THE SOLE LIABILITY AND
     RESPONSIBILITY  OF

                                                                              26



     ADMINISTRATIVE  AGENT AND SUCH LETTER OF CREDIT ISSUER BEING TO HANDLE EACH
     BANK'S SHARE ON AS FAVORABLE A BASIS AS ADMINISTRATIVE AGENT OR SUCH LETTER
     OF CREDIT ISSUER HANDLES ITS OWN SHARE.  NEITHER  ADMINISTRATIVE  AGENT NOR
     ANY OTHER LETTER OF CREDIT ISSUER SHALL HAVE ANY DUTIES OR RESPONSIBILITIES
     EXCEPT THOSE  EXPRESSLY  SET FORTH HEREIN AND THOSE DUTIES AND  LIABILITIES
     SHALL BE SUBJECT TO THE  LIMITATIONS AND  QUALIFICATIONS  SET FORTH HEREIN.
     FURTHERMORE, NEITHER ADMINISTRATIVE AGENT, ANY LETTER OF CREDIT ISSUER, NOR
     ANY OF THEIR  DIRECTORS,  OFFICERS,  OR  EMPLOYEES  SHALL BE LIABLE FOR ANY
     ACTION  TAKEN OR OMITTED  (WHETHER OR NOT SUCH  ACTION  TAKEN OR OMITTED IS
     EXPRESSLY SET FORTH  HEREIN)  UNDER OR IN CONNECTION  HEREWITH OR UNDER ANY
     OTHER  INSTRUMENT  OR DOCUMENT  IN  CONNECTION  HEREWITH,  EXCEPT FOR GROSS
     NEGLIGENCE  OR WILLFUL  MISCONDUCT.  Neither  Administrative  Agent nor any
     other  Letter of Credit  Issuer  shall  incur  any  liability  to any Bank,
     Borrower,  or any  Affiliate  of any Bank or  Borrower,  in acting upon any
     notice, document, order, consent, certificate,  warrant or other instrument
     reasonably believed by Administrative Agent or such Letter of Credit Issuer
     to be genuine or authentic and to be signed by the proper party.

          (c) No Bank will be obligated  to lend to Borrower  hereunder or incur
     Letter of Credit  Exposure,  and  Borrower  shall not be entitled to borrow
     hereunder or obtain Letters of Credit  hereunder,  in an amount which would
     cause the  Outstanding  Credit to exceed the Borrowing Base then in effect.
     No Bank shall be obligated to fund Borrowings  hereunder and Borrower shall
     not be entitled to Borrowings hereunder during the existence of a Borrowing
     Base  Deficiency.  Nothing in this Section  3.1(c) shall be deemed to limit
     any Bank's obligation to reimburse any Letter of Credit Issuer with respect
     to its  participation in Letters of Credit as a result of the drawing under
     any Letter of Credit pursuant to Section 3.1(b).

               (iv) in the case of a Eurodollar  Borrowing,  the duration of the
          Interest Period applicable  thereto,  subject to the provisions of the
          definition of Interest Period.

          (b) Upon  receipt of a Request  for  Borrowing,  Administrative  Agent
     shall promptly  notify each Bank of the contents  thereof and the amount of
     the Borrowing to be loaned by such Bank pursuant thereto,  and such Request

          (c) Not later than 12:00 noon (Dallas, Texas time) on the date of each

     specified in Section 7.2 has not been satisfied,  Administrative Agent will
     make  the  funds  so  received   from  Banks   available   to  Borrower  at
     Administrative Agent's aforesaid address.

     SECTION 3.3 METHOD OF REQUESTING LETTERS OF CREDIT.

          (a) In order to request any Letter of Credit hereunder, Borrower shall

               (iii) the purpose of such Letter of Credit.

          (b) Upon  receipt of a Request  for  Letter of Credit,  Administrative
     Agent shall  promptly  notify each Bank and the  proposed  Letter of Credit
     Issuer of the  contents  thereof,  including  the  amount of the  requested
     Letter  of  Credit,  and such  Request  for  Letter  of  Credit  shall  not
     thereafter be revocable by Borrower.

          (c) No later  than 12:00 noon  (Dallas,  Texas  time) on the date each

     Administrative  Agent or such other applicable Letter of Credit Issuer will
     issue and deliver  such Letter of Credit  pursuant to the  instructions  of
     Borrower.

     SECTION 3.4 NOTES. Each Bank's Commitment  Percentage of the Revolving Loan
shall be  evidenced  by a single  Note  payable  to the order of such Bank in an
amount equal to such Bank's Commitment.

                                                                              28




     SECTION 3.5 INTEREST RATES; PAYMENTS.

          (a) The principal amount of the Base Rate Loan outstanding from day to
     day shall  bear  interest  at a rate per annum  equal to the sum of (i) the
     Applicable  Margin plus (ii) the applicable Base Rate in effect from day to
     day;  provided  that in no event shall the rate charged  hereunder or under
     the Notes exceed the Maximum  Lawful  Rate.  Interest on the Base Rate Loan
     shall  be  payable  as it  accrues  on  each  Quarterly  Date,  and  on the
     Termination Date.

          (b) The principal  amount of each Eurodollar Loan outstanding from day
     to day shall bear interest for the Interest Period applicable  thereto at a
     rate per annum equal to the sum of (i) the Applicable  Margin plus (ii) the
     applicable  Adjusted  Eurodollar Rate;  provided that in no event shall the
     rate charged  hereunder or under the Notes exceed the Maximum  Lawful Rate.
     Interest on any portion of the principal of each Eurodollar Loan subject to
     an Interest Period of one (1), two (2) or three (3) months shall be payable
     on the last day of the Interest Period applicable thereto.  Interest on any
     portion of the  principal  of each  Eurodollar  Loan subject to an Interest
     Period of six (6),  nine (9), or twelve (12) months shall be payable on the
     last day of the Interest  Period  applicable  thereto and on each Quarterly
     Date.

          (c) So long as no  Default or Event of  Default  shall be  continuing,
     subject to the  provisions  of this  Section 3.5,  Borrower  shall have the
     option of having all or any portion of the principal  outstanding under the
     Revolving  Loan be a Base  Rate Loan or one (1) or more  Eurodollar  Loans,
     which shall bear interest at rates determined by reference to the Base Rate
     and  the  Adjusted  Eurodollar  Rate,  respectively;  provided,  that  each
     Eurodollar  Loan shall be in a minimum amount of $2,000,000 and shall be in
     an  amount  which  is an  integral  multiple  of  $500,000.  Prior  to  the
     termination of each Interest Period with respect to each  Eurodollar  Loan,
     Borrower  shall  give  written  notice  (a  "NOTICE  OF   CONTINUATION   OR
     CONVERSION")  in the form of  Exhibit H attached  hereto to  Administrative
     Agent of the Type of Loan which shall be  applicable  to the  principal  of
     such  Eurodollar  Loan upon the  expiration of such Interest  Period.  Such
     Notice of Continuation or Conversion shall be given to Administrative Agent
     at least one (1)  Domestic  Business  Day,  in the case of a Base Rate Loan
     selection  and  three  (3)  Eurodollar  Business  Days,  in the  case  of a
     Eurodollar Loan selection,  prior to the termination of the Interest Period
     then expiring.  If Borrower shall specify a Eurodollar Loan, such Notice of
     Continuation or Conversion  shall also specify the length of the succeeding
     Interest  Period (subject to the provisions of the definition of such term)
     selected by Borrower.  Each Notice of Continuation  or Conversion  shall be
     irrevocable  and  effective  upon  notification  thereof to  Administrative
     Agent. If the required Notice of Continuation or Conversion  shall not have
     been timely received by Administrative  Agent,  Borrower shall be deemed to
     have  elected  that the  principal  of the  Eurodollar  Loan subject to the
     Interest  Period then  expiring be Converted to the Base Rate Loan upon the
     expiration  of such  Interest  Period and  Borrower  will be deemed to have
     given  Administrative  Agent  notice  of  such  election.  Subject  to  the
     limitations  set forth in this  Section  3.5(c) on the amount and number of
     Eurodollar Loans,  Borrower shall have the right to Convert all or any part
     of the Base Rate Loan to a Eurodollar Loan by giving Administrative Agent a
     Notice of  Continuation  or  Conversion of such election at least three (3)
     Eurodollar Business Days prior to the date on which Borrower elects to make
     such  Conversion (a "CONVERSION  DATE").  The  Conversion  Date selected by
     Borrower shall be a Eurodollar  Business Day.  Notwithstanding  anything in
     this Section 3.5 to the  contrary,  no portion of the principal of the Base
     Rate Loan may be Converted to a Eurodollar  Loan and no Eurodollar Loan may
     be

                                                                              29



     Continued  as such when any Default or Event of Default has occurred and is
     continuing,  but each such Eurodollar Loan shall be automatically Converted
     to the Base Rate Loan on the last day of each applicable  Interest  Period.
     Borrower  shall not be  permitted  to have more than  seven (7)  Eurodollar
     Loans in effect at any time.

          (d)  Notwithstanding  anything  to the  contrary  set forth in Section
     3.5(a)  or  Section  3.5(b)  above,  after  the  occurrence  of an Event of
     Default,  interest shall accrue on the outstanding principal balance of the
     Revolving  Loan,  and to the extent  permitted  by Law,  on the accrued but
     unpaid  interest on the Revolving Loan and all other  Obligations  from the
     period from and  including  the  occurrence of such Event of Default to but
     excluding  the date the same is  remedied  at a rate per annum equal to the
     lesser of (a) the Default Rate, and (b) the Maximum Lawful Rate.

          (e) Administrative Agent shall determine each interest rate applicable
     to the Revolving Loan in accordance  with the terms hereof.  Administrative
     Agent shall promptly notify Borrower and Banks by telex,  telecopy or cable
     of each rate of interest so determined, and its determination thereof shall
     be conclusive in the absence of manifest error.

          (f) Notwithstanding the foregoing, if at any time the rate of interest
     calculated with reference to the Base Rate or the Eurodollar Rate hereunder
     (the "CONTRACT RATE") is limited to the Maximum Lawful Rate, any subsequent
     reductions  in the  contract  rate shall not reduce the rate of interest on
     the Revolving  Loan below the Maximum Lawful Rate until the total amount of
     interest  accrued equals the amount of interest which would have accrued if
     the  contract  rate had at all times been in  effect.  In the event that at
     maturity (stated or by acceleration),  or at final payment of any Note, the
     total  amount of  interest  paid or  accrued  on such Note is less than the
     amount of interest which would have accrued if the contract rate had at all
     times been in effect with respect thereto, then at such time, to the extent
     permitted by law,  Borrower  shall pay to the holder of such Note an amount
     equal to the  difference  between  (i) the lesser of the amount of interest
     which  would  have  accrued if the  contract  rate had at all times been in
     effect and the amount of interest  which would have  accrued if the Maximum
     Lawful  Rate had at all  times  been in  effect,  and (ii)  the  amount  of
     interest actually paid on such Note.

          (g)  Interest  payable  hereunder  on each  Eurodollar  Loan  shall be
     computed  based on the number of actual  days  elapsed  assuming  that each
     calendar year consisted of 360 days. Interest payable hereunder on the Base
     Rate Loan  shall be  computed  based on the actual  number of days  elapsed
     assuming that each  calendar  year  consisted of 365 days (or 366 days in a
     leap year).

     SECTION 3.6  MANDATORY  PREPAYMENTS.  Upon the  occurrence of any Borrowing
Base Deficiency,  Borrower shall make the mandatory prepayments of the Revolving
Loan required by Section 5.4 hereof.

     SECTION 3.7 VOLUNTARY PREPAYMENTS. Borrower may, subject to Section 3.3 and
the other  provisions of this  Agreement,  prepay the principal of the Revolving
Loan in whole or in part. Any partial prepayment shall be in a minimum amount of
$500,000 and shall be in an integral multiple of $100,000.

                                                                              30




     SECTION 3.8 VOLUNTARY REDUCTION OF COMMITMENTS.  Borrower may, by notice to
Administrative Agent five (5) Domestic Business Days prior to the effective date
of any such  reduction,  reduce the Total  Commitment  (and  thereby  reduce the
Commitment of each Bank ratably) in amounts not less than  $5,000,000  and in an
amount which is an integral multiple of $1,000,000. On the effective date of any
such  reduction,  Borrower  shall,  to the extent  required  as a result of such
reduction,  make  a  principal  payment  on  the  Revolving  Loan  in an  amount
sufficient to cause the principal balance of the Revolving Loan then outstanding
to  be  equal  to  or  less  than  the  Total  Commitment  as  thereby  reduced.
Notwithstanding  the  foregoing,  Borrower shall not be permitted to voluntarily
reduce  the Total  Commitment  to an amount  less than the  aggregate  Letter of
Credit Exposure of all Banks.

     SECTION 3.9 TERMINATION OF  COMMITMENTS;  FINAL MATURITY OF REVOLVING LOAN.
The Total Commitment (and the Commitment of each Bank) shall terminate,  and the
entire outstanding principal balance of the Revolving Loan, all interest accrued
thereon,  all  accrued  but  unpaid  fees  hereunder  and all other  outstanding
Obligations shall be due and payable in full on the Termination Date.

     SECTION 3.10  APPLICATION OF PAYMENTS.  Each repayment  pursuant to Section
3.6,  Section  3.7,  Section  3.8,  Section  3.9 and  Section  5.4 shall be made
together with accrued interest on the amount repaid to the date of payment,  and
shall be applied in accordance with Section 4.2 and the other provisions of this
Agreement.

     SECTION 3.11  COMMITMENT  FEE. On the  Termination  Date, on each Quarterly
Date  prior to the  Termination  Date,  and,  in the event the  Commitments  are
terminated in their entirety prior to the Termination  Date, on the date of such
termination, Borrower shall pay to Administrative Agent, for the ratable benefit
of each Bank based on each Bank's Commitment Percentage,  a commitment fee equal
to the  Commitment  Fee  Percentage  in effect from day to day (applied on a per
annum  basis and  computed  on the basis of actual  days  elapsed and as if each
calendar year consisted of 365 days (or 366 days in a leap year)) of the average
daily  Availability  for the Fiscal Quarter (or portion  thereof)  ending on the
date such payment is due.

     SECTION 3.12 AGENCY AND OTHER FEES.  Borrower  shall pay to  Administrative
Agent and its  Affiliates  such other  fees and  amounts  as  Borrower  shall be
required to pay to  Administrative  Agent and its  Affiliates  from time to time
pursuant to any separate agreement between Borrower and Administrative  Agent or
such Affiliates. Such fees and other amounts shall be retained by Administrative
Agent and its  Affiliates,  and no Bank  (other  than Bank One)  shall  have any
interest   therein.   Administrative   Agent  may  disburse  any  fees  paid  to
Administrative  Agent and its  Affiliates  pursuant to this  Section 3.12 in any
manner Administrative Agent desires in its sole discretion.

                                   ARTICLE IV
                               GENERAL PROVISIONS

     SECTION  4.1  DELIVERY  AND  ENDORSEMENT  OF NOTES.  On the  Closing  Date,
Administrative  Agent shall  deliver to each Bank the Note payable to such Bank.
Each Bank may endorse (and prior to any  transfer of its Note shall  endorse) on
the  schedules  attached  and forming a part  thereof  appropriate  notations to
evidence the date and amount of its Commitment

                                                                              31



Percentage of each Borrowing,  the Interest Period applicable  thereto,  and the
date and amount of each  payment of  principal  made by  Borrower  with  respect
thereto;  provided that the failure by any Bank to so endorse its Note shall not
affect the  liability of Borrower for the  repayment of all amounts  outstanding
under such Note together with interest thereon.  Each Bank is hereby irrevocably
authorized  by  Borrower to endorse its Note and to attach to and make a part of
any such Note a continuation of any such schedule as required.

     SECTION 4.2 GENERAL PROVISIONS AS TO PAYMENTS.

          (a) Borrower shall make each payment of principal of, and interest on,
     the Revolving Loan, and all fees payable hereunder shall be paid, not later
     than 12:00 noon  (Dallas,  Texas  time) on the date when due, in Federal or
     other funds immediately available in Dallas, Texas, to Administrative Agent
     at its address set forth on Schedule 2.1 hereto, without defense,  set-off,
     deduction or counterclaim.  Administrative Agent will promptly (and if such
     payment is received by Administrative  Agent by 10:00 a.m.  (Dallas,  Texas
     time), and otherwise if reasonably possible,  on the same Domestic Business
     Day) distribute to each Bank its Commitment Percentage of each such payment
     received by  Administrative  Agent for the account of Banks.  Whenever  any
     payment  of  principal  of, or  interest  on, the Base Rate Loan or of fees
     shall be due on a day which is not a Domestic  Business  Day,  the date for
     payment thereof shall be extended to the next succeeding  Domestic Business
     Day.  Whenever any payment of principal  of, or interest on, any portion of
     any  Eurodollar  Loan  shall  be due  on a day  which  is not a  Eurodollar
     Business  Day, the date for payment  thereof  shall be extended to the next
     succeeding  Eurodollar  Business  Day  (subject  to the  provisions  of the
     definition of Interest Period). If the date for any payment of principal is
     extended  by  operation  of Law or  otherwise,  interest  thereon  shall be
     payable for such extended time.  Borrower hereby authorizes  Administrative
     Agent  to  charge  from  time  to time  against  Borrower's  accounts  with
     Administrative Agent any amount then due.

          (b) Prior to the  occurrence  of an Event of  Default,  all  principal
     payments  received  by Banks with  respect to the  Revolving  Loan shall be
     applied first to Eurodollar Loans  outstanding with Interest Periods ending
     on the  date of such  payment,  then to the  Base  Rate  Loan,  and then to
     Eurodollar  Loans  next  maturing  until  such  principal  payment is fully
     applied.

          (c) After the occurrence of an Event of Default, all amounts collected
     or received by  Administrative  Agent or any Bank shall be applied first to
     the  payment  of all  proper  costs  incurred  by  Administrative  Agent in
     connection with the collection thereof (including  reasonable  expenses and
     disbursements of Administrative Agent), second to the payment of all proper
     costs  incurred  by  Banks  in  connection  with  the  collection   thereof
     (including  reasonable  expenses and disbursements of Banks),  third to the
     reimbursement  of any advances made by Banks to effect  performance  of any
     unperformed  covenants  of any Credit  Party under any of the Loan  Papers,
     fourth to the payment of any unpaid fees required pursuant to Section 3.11,
     fifth to the payment of any unpaid fees required pursuant to Section 3.1(b)
     and  Section  3.10,  sixth,  to  payment  to each  Bank  of its  Commitment
     Percentage of the  outstanding  principal of the Revolving Loan and accrued
     but unpaid interest thereon, and seventh to establish the deposits required
     in Section 3.1(b).  All payments received by a Bank after the occurrence of
     an Event of Default for  application to the principal of the Revolving Loan
     shall be applied by such Bank in the manner provided in Section 4.2(b).

                                                                              32




                                   ARTICLE V
                                 BORROWING BASE

     SECTION  5.1  RESERVE  REPORT;   PROPOSED  BORROWING  BASE  AND  CONFORMING
BORROWING BASE. The aggregate  amount of credit available to Borrower under this
Agreement shall be limited by a Borrowing Base (herein so called) which shall be
determined  by Banks at the  times  and in  accordance  with the  standards  and
procedures set forth in this Article V. As soon as available and in any event by
February 28 and August 31 of each year  commencing  February 28, 2003,  Borrower
shall deliver to Administrative Agent and each Bank a Reserve Report prepared as
of  the   immediately   preceding   December   31  and  June  30   respectively.
Simultaneously  with the delivery to Administrative  Agent and each Bank of each
Reserve Report,  Borrower shall notify Administrative Agent and each Bank of the
amount of the Borrowing Base which  Borrower  requests  become  effective on the
next  Redetermination Date (or such date promptly following such Redetermination
Date as  Required  Banks  shall  elect).  Banks may,  in their sole  discretion,
establish a Borrowing  Base which is higher than the  Borrowing  Base that would
otherwise  be in effect if Banks  determined  the  Borrowing  Base based on each
Bank's  application  of the  credit  standards  and other  criteria  customarily
applied by such Bank in the  determination  of credit  limitations for companies
similar  to  Borrower  ("CONFORMING  CREDIT  CRITERIA").  At the  time  of  each
Redetermination,  Banks shall also determine what the Borrowing Base would be if
they applied  Conforming  Credit Criteria (the "CONFORMING  BORROWING BASE"). If
Banks do not  determine a  Conforming  Borrowing  Base,  the  Borrowing  Base as
redetermined  shall also be the  Conforming  Borrowing Base for purposes of this
Agreement.

     SECTION  5.2  SCHEDULED  REDETERMINATIONS  OF THE  BORROWING  BASE  AND THE
CONFORMING  BORROWING  BASE;  PROCEDURES  AND  STANDARDS.  Based  in part on the
Reserve  Reports made  available to Banks  pursuant to Section 5.1,  Banks shall
redetermine the Borrowing Base and the Conforming  Borrowing Base on or prior to
the next  Redetermination  Date (or such date promptly  thereafter as reasonably
possible based on the engineering and other information available to Banks). Any
Borrowing Base or Conforming  Borrowing Base which becomes effective as a result
of any Redetermination of the Borrowing Base or Conforming  Borrowing Base shall
be subject to the following restrictions:  (a) such Borrowing Base or Conforming
Borrowing  Base  shall not exceed  the  Borrowing  Base  requested  by  Borrower
pursuant to Section 5.1 or Section 5.3 (as applicable),  (b) such Borrowing Base
or  Conforming  Borrowing  Base shall not exceed  the Total  Commitment  then in
effect,  (c) to the extent such  Borrowing  Base or  Conforming  Borrowing  Base
represents an increase from the Borrowing Base or the Conforming  Borrowing Base
(as applicable) in effect prior to such Redetermination,  such Borrowing Base or
Conforming  Borrowing Base shall be approved by all Banks, and (d) to the extent
such  Borrowing Base or Conforming  Borrowing Base  represents a decrease in the
Borrowing Base or the Conforming  Borrowing Base (as applicable) in effect prior
to such  Redetermination,  or a  reaffirmation  of such prior  Borrowing Base or
Conforming  Borrowing  Base,  such Borrowing  Base or Conforming  Borrowing Base
shall be approved by Required Banks. Each Redetermination shall be made by Banks
in  their  sole  discretion.   Without   limiting  such   discretion,   Borrower
acknowledges  and  agrees  that  Banks (i) may make such  assumptions  regarding
appropriate  existing  and  projected  pricing  for  Hydrocarbons  as they  deem
appropriate in their sole discretion,  (ii) may make such assumptions  regarding
projected  rates and quantities of future  production of  Hydrocarbons  from the
Mineral  Interests  owned by  Borrower  as they

                                                                              33




deem appropriate in their sole discretion, (iii) may consider the projected cash
requirements of the Credit Parties,  (iv) are not required to consider any asset
other than Proved Mineral Interests owned by Borrower which are subject to first
and prior  Liens in favor of  Administrative  Agent for the  ratable  benefit of
Banks to the extent required by Section 6.1 hereof,  and (v) may make such other
assumptions,  considerations  and  exclusions as Banks deem  appropriate  in the
exercise of their sole  discretion.  It is further  acknowledged and agreed that
each Bank may consider such other credit factors as it deems  appropriate in the
exercise of its sole  discretion and shall have no obligation in connection with
any  Redetermination  to approve any  increase  from the  Borrowing  Base or the
Conforming  Borrowing  Base  in  effect  prior  to  such  Redetermination.   The
Conforming  Borrowing  Base  shall  also be  determined  by Banks in their  sole
discretion, and in determining the amount of the Conforming Borrowing Base, each
Bank may make the assumptions and consider the factors and criteria set forth in
subclauses (a) through (d) and (i) through (v) above;  provided,  that each Bank
shall apply Conforming Credit Criteria.  Promptly following any  Redetermination
of the Borrowing Base and the Conforming  Borrowing Base,  Administrative  Agent
shall notify  Borrower of the amount of the  Borrowing  Base and the  Conforming
Borrowing Base as  redetermined,  which Borrowing Base and Conforming  Borrowing
Base shall be  effective  as of the date  specified  in such  notice,  and shall
remain  in  effect  for  all   purposes  of  this   Agreement   until  the  next
Redetermination.

     SECTION 5.3 SPECIAL REDETERMINATION.

          (a) In addition to Scheduled  Redeterminations,  Borrower and Required
     Banks shall each be permitted to request a Special  Redetermination  of the
     Borrowing Base and the Conforming  Borrowing Base once in each Fiscal Year.
     Any request by Required  Banks  pursuant to this  Section  5.3(a)  shall be
     submitted to  Administrative  Agent and  Borrower.  Any request by Borrower
     pursuant to this Section 5.3(a) shall be submitted to Administrative  Agent
     and each Bank and at the time of such request Borrower shall (i) deliver to
     Administrative  Agent and each Bank a Reserve Report,  and (ii) also notify
     Administrative  Agent  and each Bank of the  Borrowing  Base  requested  by
     Borrower in connection with such Special  Redetermination.  (b) Any Special
     Redetermination  shall be made by Banks in accordance  with the  procedures
     and standards set forth in Section 5.2;  provided,  that, no Reserve Report
     will be  required  to be  delivered  to  Administrative  Agent and Banks in
     connection  with any Special  Redetermination  requested by Required  Banks
     pursuant to Section 5.3(a) above.

     SECTION 5.4  BORROWING  BASE  DEFICIENCY.  To the extent a  Borrowing  Base
Deficiency exists after giving effect to any Redetermination,  Borrower shall be
obligated to  eliminate  such  Borrowing  Base  Deficiency  over a period not to
exceed six (6) months from the effective date of such  Redetermination by making
six (6)  mandatory,  equal,  consecutive,  monthly  payments of principal on the
Revolving  Loan,  each of which  shall be in the amount of one sixth  (1/6th) of
such Borrowing  Base  Deficiency,  or in the event that the remaining  principal
outstanding under the Revolving Loan is less than the Borrowing Base Deficiency,
then in the amount of one sixth (1/6th) of the remaining  principal  outstanding
under the Revolving Loan. The first of such six (6) payments shall be due on the
thirtieth  (30th) day following the effective date of each such  Redetermination
and  each  subsequent  payment  shall  be due  on the  same  day of  each  month
thereafter (or if there is no corresponding day of any subsequent month, then on
the  last  day of such  month)  (each  such  date is  referred  to  herein  as a
"BORROWING BASE DEFICIENCY

                                                                              34




PAYMENT DATE"). If a Borrowing Base Deficiency cannot be eliminated  pursuant to
this Section 5.4 by  prepayment  of the  Revolving  Loan in full (as a result of
outstanding  Letter of  Credit  Exposure),  on each  borrowing  base  deficiency
payment date, Borrower shall also deposit cash with Administrative  Agent, to be
held by Administrative  Agent to secure outstanding Letter of Credit Exposure in
the manner contemplated by Section 3.1(b), an amount at least equal to one sixth
(1/6th) of the balance of such Borrowing Base Deficiency (i.e., one-sixth of the
difference  between the Borrowing Base Deficiency and the remaining  outstanding
principal   under   the   Revolving   Loan  on  the   effective   date  of  such
Redetermination).

     SECTION 5.5 INITIAL BORROWING BASE AND INITIAL  CONFORMING  BORROWING BASE.
Notwithstanding  anything to the contrary  contained herein,  the Borrowing Base
and the Conforming  Borrowing Base in effect during the period commencing on the
Closing Date and ending on the effective date of the first Redetermination after
the Closing Date shall be the Initial Borrowing Base and the Initial  Conforming
Borrowing  Base,  respectively.  The  Mineral  Interests  acquired  by  Borrower
pursuant to the terms of that certain Asset Purchase Agreement, dated as of June
19,  2002,  by and between  Borrower  and COHO  Resources,  Inc.,  have not been
evaluated for purposes of  establishing  the Initial  Borrowing Base and Initial
Conforming Borrowing Base.

     SECTION 6.1 SECURITY.

          (a) The Obligations shall be secured by first and prior Liens (subject
     only to Permitted  Encumbrances)  covering and  encumbering (i) one hundred
     percent  (100%)  of  all  Borrowing  Base  Properties,  and  prior  to  any
     Distributions  being  permitted  to be  made to any  Restricted  Subsidiary
     pursuant  to  the  terms  of  Section  10.2(b)  and/or  the  definition  of
     "Permitted  Investments," all of the issued and outstanding Equity owned by
     Borrower and each Restricted Subsidiary of each such Restricted Subsidiary.
     On the Closing Date, Borrower shall deliver to Administrative Agent for the
     ratable  benefit of each Bank, the Mortgages and Assignments and Amendments
     to Mortgages in form and substance  acceptable to Administrative  Agent and
     duly  executed  by  Borrower,   together   with  such  other   assignments,
     conveyances,  amendments, agreements and other writings, including, without
     limitation,  UCC-1 and UCC-3 financing statements (each duly authorized and
     executed,  as applicable) as  Administrative  Agent shall deem necessary or
     appropriate  to grant,  evidence  and perfect  first and prior Liens in all
     Borrowing Base Properties and other interests of Borrower  required by this
     Section 6.1(a).  Borrower hereby authorizes  Administrative  Agent, and its
     agents,  successors  and assigns,  to file any and all necessary  financing
     statements under the Uniform  Commercial Code,  assignments or continuation
     statements  as  necessary  from  time to time  (in  Administrative  Agent's
     discretion)  to  perfect  (or  continue  perfection  of) the Liens  granted
     pursuant to the Loan Papers.

          (b) On or before each  Redetermination Date after the Closing Date and
     at such  other  times as  Administrative  Agent  or  Required  Banks  shall
     request, Borrower and its Restricted Subsidiaries shall execute and deliver
     to Administrative Agent, for the ratable benefit of each Bank, Mortgages in
     form and substance  acceptable to Administrative Agent and duly executed by
     Borrower and any such Restricted  Subsidiary (as applicable)  together with
     such  other  assignments,  conveyances,  amendments,  agreements  and other
     writings,  including,  without

                                                                              35




     limitation,  UCC-1 financing statements (each duly authorized and executed)
     as  Administrative  Agent shall deem  necessary  or  appropriate  to grant,
     evidence and perfect the Liens  required by Section  6.1(a)  preceding with
     respect  to  Borrowing  Base  Properties   acquired  by  Borrower  and  its
     Restricted  Subsidiaries  subsequent to the last date on which  Borrower or
     any  such  Restricted  Subsidiary  was  required  to  execute  and  deliver
     Mortgages  pursuant to this Section 6.1(b),  or which, for any other reason
     are not the subject of valid,  enforceable,  perfected first priority Liens
     (subject only to Permitted  Encumbrances) in favor of Administrative  Agent
     for the ratable benefit of Banks.

          (c) At any time  Borrower  or any of its  Subsidiaries  is required to
     execute  and  deliver  Mortgages  and/or   Assignments  and  Amendments  to
     Mortgages to  Administrative  Agent pursuant to this Section 6.1,  Borrower
     shall  also  deliver  to  Administrative  Agent  such  opinions  of counsel
     (including, if so requested,  title opinions, and in each case addressed to
     Administrative  Agent) and other evidence of title as Administrative  Agent
     shall  deem  necessary  or  appropriate  to verify (i)  Borrower's  or such
     Subsidiary's  title to the  Required  Reserve  Value of the Proved  Mineral
     Interests  which are  subject  to such  Mortgages,  and (ii) the  validity,
     perfection  and priority of the Liens created by such Mortgages (as amended
     by the  Assignments  and Amendments to Mortgages,  as applicable)  and such
     other  matters  regarding  such  Mortgages  as  Administrative  Agent shall
     reasonably request.

          (d) To the extent  required  or  contemplated  by the terms of Section
     6.1(a)(ii),  Section 10.2 and the  definition of  "Permitted  Investments,"
     Borrower or any  Indirect  Subsidiary  (as  applicable)  shall  execute and
     deliver to Administrative Agent a Borrower Pledge Agreement or a Subsidiary
     Pledge  Agreement (as applicable)  together with (i) all  certificates  (or
     other evidence  acceptable to  Administrative  Agent) evidencing the issued
     and  outstanding  Equity of any such  Restricted  Subsidiary of every class
     owned by Borrower or such Indirect  Subsidiary (as applicable)  which shall
     be duly  endorsed  or  accompanied  by stock  powers  executed in blank (as
     applicable),  and (ii) such UCC-1  financing  statements as  Administrative
     Agent shall deem necessary or  appropriate  to grant,  evidence and perfect
     the Liens required by Section 6.1(a)(ii) and Section 10.2 in the issued and
     outstanding Equity of each such Restricted Subsidiary.

made to any  Restricted  Subsidiary  pursuant  to the terms of Section  10.2(b),
payment and  performance of the  Obligations  shall be fully  guaranteed by each
such Restricted  Subsidiary pursuant to a Facility Guaranty,  and Borrower shall
cause any such  applicable  Restricted  Subsidiary  to  execute  and  deliver to
Administrative Agent such Facility Guaranty.

material  respects with all applicable  Laws.  Except in such instances where an
omission or failure would not have a Material  Adverse Effect,  (a) all returns,
reports and notices required to be filed with any regulatory agency with respect
to any Plan  have  been  filed  timely,  and (b) no  Credit  Party nor any ERISA

have a Material Adverse Effect.  No Credit Party knows of any proposed  material
Tax  assessment  against it and all Tax  liabilities  of each  Credit  Party are
adequately  provided  for.  Except as disclosed in writing to Banks prior to the
date  hereof,  no income tax  liability in excess of $50,000 of any Credit Party

Immaterial Title Deficiencies, all such Mineral Interests are valid, subsisting,
and in full force and effect, and all rentals,  royalties, and other amounts due
and  payable  in respect  thereof  have been duly  paid.  Without  regard to any
consent or non-consent  provisions of any joint operating agreement covering any

provided,  however,  no payment of Taxes or claims  shall be required if (i) the
amount,  applicability  or validity thereof is currently being contested in good
faith by  appropriate  action  promptly  initiated and  diligently  conducted in

     Mineral  Interests  so  long as  such  Mineral  Interests  are  capable  of
     producing  Hydrocarbons  and  accompanying  elements in paying  quantities,
     except  where  such  failure to comply  would not have a  Material  Adverse
     Effect.

          (b) Borrower  will,  and will cause each other Credit Party to, comply
     in all respects with all contracts and agreements applicable to or relating
     to its Mineral  Interest or the  production  and sale of  Hydrocarbons  and

     where such  failure to comply  would not have a  Material  Adverse  Effect;
     provided, further that, no item of operating equipment need be so repaired,
     renewed,  replaced,  added to or improved,  if Borrower shall in good faith
     determine  that such action is not necessary or desirable for the continued
     efficient and profitable operation of the business of such Credit Party.

judgment by a court of competent  jurisdiction  to have  resulted from the gross
negligence or willful misconduct of Administrative Agent. The obligations of the
Banks under this  Section  13.8 shall  survive  payment of the  Obligations  and
termination of this Agreement.

     SECTION 13.9 NOTICE OF DEFAULT. Administrative Agent shall not be deemed to
have  knowledge or notice of the  occurrence  of any Default or Event of Default
hereunder unless Administrative Agent has received written notice from a Bank or
Borrower referring to this Agreement describing such Default or Event of Default
and  stating  that such  notice  is a "notice  of  default".  In the event  that
Administrative  Agent  receives such a notice,  Administrative  Agent shall give
prompt notice thereof to the Banks.

     SECTION  13.10  RIGHTS AS A BANK.  In the event  Administrative  Agent is a
Bank,  Administrative  Agent shall have the same rights and powers hereunder and
under any other Loan Paper with  respect  to its  Commitment  and its  Revolving
Loans as any Bank and may exercise the same as though it were not Administrative
Agent,  and the term "Bank" or "Banks"  shall,  at any time when  Administrative
Agent  is a  Bank,  unless  the  context  otherwise  indicates,  include  in its
individual capacity. Administrative Agent and its Affiliates may accept deposits
from, lend money to, and generally engage in any kind of trust,  debt, equity or
other  transaction,  in addition to those  contemplated by this Agreement or any
other Loan Paper,  with Borrower or any of its Subsidiaries in which Borrower or
such Subsidiary is not restricted hereby from engaging with any other Person.

     SECTION 13.11 BANK CREDIT  DECISION.  Each Bank  acknowledges  that it has,
independently  and  without  reliance  upon  Administrative   Agent,  Sole  Lead
Arranger,  Book  Manager or any other  Agent or Bank and based on the  financial
statements  prepared by Borrower and such other  documents and information as it
has deemed appropriate,  made its own credit analysis and decision to enter into
this Agreement and the other Loan Papers.  Each Bank also  acknowledges  that it
will,  independently and without reliance upon  Administrative  Agent, Sole Lead
Arranger,  Book  Manager or any other Agent or Bank and based on such  documents
and information as it shall deem  appropriate at the time,  continue to make its
own credit decisions in taking or not taking action under this Agreement and the
other Loan Papers.

     SECTION 13.12  SUCCESSOR  ADMINISTRATIVE  AGENT.  Administrative  Agent may
resign at any time by giving written notice thereof to Banks and Borrower,  such
resignation to be effective upon the  appointment of a successor  Administrative
Agent or, if no successor  Administrative  Agent has been appointed,  forty-five
(45) days after the retiring  Administrative Agent gives notice of its intention
to resign. Administrative Agent may be removed at any time with or without cause
by written notice received by  Administrative  Agent from Required  Banks,  such
removal to be effective on the date specified by Required  Banks.  Upon any such
resignation  or removal,  Required  Banks  shall have the right to  appoint,  on
behalf of Borrower and the Banks, a successor  Administrative Agent, which shall
be  approved  by  Borrower,  such  approval  not  to be  unreasonably  withheld;
provided,  that,  Borrower  shall not have the right to

                                                                              60



approve any successor  Administrative  Agent appointed during the continuance of
any Default. If no successor  Administrative  Agent shall have been so appointed
by Required  Banks within  thirty (30) days after the  resigning  Administrative
Agent's   giving  notice  of  its  intention  to  resign,   then  the  resigning
Administrative  Agent may appoint,  on behalf of Borrower and Banks, a successor
Administrative  Agent which shall be approved by Borrower,  such approval not to
be unreasonably withheld;  provided,  that, Borrower shall not have the right to
approve any successor  Administrative  Agent appointed during the continuance of
any  Default.  If  Administrative  Agent has  resigned  or been  removed  and no
successor  Administrative  Agent has been  appointed,  Banks may perform all the
duties of Administrative Agent hereunder and Borrower shall make all payments in
respect of the  Obligations  to the  applicable  Bank and for all other purposes
shall deal directly with the Banks. No successor  Administrative  Agent shall be
deemed to be appointed hereunder until such successor  Administrative  Agent has
accepted the  appointment.  Any such successor  Administrative  Agent shall be a
commercial bank having capital and retained  earnings of at least  $100,000,000.
Upon the acceptance of any  appointment as  Administrative  Agent hereunder by a
successor  Administrative  Agent,  such  successor  Administrative  Agent  shall
thereupon succeed to and become vested with all the rights,  powers,  privileges
and  duties  of  the  resigning  or  removed   Administrative  Agent.  Upon  the
effectiveness  of the  resignation  or  removal  of  Administrative  Agent,  the
resigning or removed  Administrative  Agent shall be discharged  from its duties
and obligations  hereunder and under the Loan Papers. After the effectiveness of
the resignation or removal of an  Administrative  Agent,  the provisions of this
Article  XIII shall  continue in effect for the  benefit of such  Administrative
Agent in respect of any actions  taken or omitted to be taken by it while it was
acting as Administrative Agent hereunder and under the other Loan Papers. In the
event  that  there  is  a  successor  to  Administrative  Agent  by  merger,  or
Administrative Agent assigns its duties and obligations to an Affiliate pursuant
to this  Section  13.12,  then the term "Prime  Rate" as used in this  Agreement
shall  mean  the  prime  rate,  base  rate or  other  analogous  rate of the new
Administrative Agent.

     SECTION  13.13  DELEGATION  TO  AFFILIATES.  Borrower  and Banks agree that
Administrative  Agent may delegate any of its duties under this Agreement to any
of its Affiliates. Any such Affiliate (and such Affiliate's directors, officers,
agents and employees)  which performs  duties in connection  with this Agreement
shall be entitled to the same benefits of the indemnification,  waiver and other
protective  provisions to which  Administrative  Agent is entitled under Article
XIII and Article XIV.

     SECTION  13.14  EXECUTION OF  COLLATERAL  DOCUMENTS.  Without  limiting the
powers and authority of Administrative  Agent described herein, the Banks hereby
empower and authorize Administrative Agent to execute and deliver to Borrower on
their behalf the Mortgages,  the  Assignments  and Amendments to Mortgages,  the
Borrower Pledge  Agreements,  the Subsidiary  Pledge  Agreements and all related
financing statements and any other financing statements,  agreements,  documents
or  instruments  as shall be necessary or  appropriate to effect the purposes of
the foregoing instruments.

     SECTION  13.15  COLLATERAL  RELEASES.  Banks hereby  empower and  authorize
Administrative  Agent to execute and  deliver to  Borrower  on their  behalf any
agreements,  documents or  instruments  as shall be necessary or  appropriate to
effect any releases of  collateral  which shall be permitted by the terms hereof
or of any other  Loan  Paper or which  shall  otherwise

                                                                              61



have been  approved by  Required  Banks (or, if required by the terms of Section
15.5, all of the Banks) in writing.

     SECTION 13.16 AGENTS.  None of the Banks  identified in this Agreement as a
"Documentation  Agent" and/or a "Syndication Agent" shall have any right, power,
obligation,  liability,  responsibility  or duty under this Agreement other than
those applicable to all Banks as such.  Without limiting the foregoing,  none of
such Documentation  Agents or Syndication Agents shall have or be deemed to have
a  fiduciary  relationship  with any  Bank.  Each  Bank  hereby  makes  the same
acknowledgments with respect to such Documentation Agents and Syndication Agents
as it makes with respect to Administrative Agent in Section 13.11.

                                  ARTICLE XIV
                             CHANGE IN CIRCUMSTANCES

     SECTION 14.1 INCREASED COST AND REDUCED RETURN.

          (a) If, after the date hereof,  the  adoption of any  applicable  law,
     rule,  or  regulation,  or any  change  in any  applicable  law,  rule,  or
     regulation,  or any change in the interpretation or administration  thereof
     by any Governmental  Authority,  central bank, or comparable agency charged
     with the  interpretation  or administration  thereof,  or compliance by any
     Bank (or its  Applicable  Lending  Office)  with any  request or  directive
     (whether  or  not  having  the  force  of  law)  of any  such  Governmental
     Authority, central bank, or comparable agency:

               (i) shall subject such Bank (or its Applicable Lending Office) to
          any tax, duty, or other charge with respect to any  Eurodollar  Loans,
          its Note, or its obligation to make  Eurodollar  Loans,  or change the
          basis  of  taxation  of any  amounts  payable  to  such  Bank  (or its
          Applicable Lending Office) under this Agreement or its Note in respect
          of any  Eurodollar  Loans (other than taxes imposed on the overall net
          income of such Bank or such Applicable Lending Office);

               (ii)  shall  impose,  modify,  or deem  applicable  any  reserve,
          special deposit,  assessment,  compulsory loan, or similar requirement
          (other than the Reserve  Requirement  utilized in the determination of
          the Adjusted  Eurodollar Rate) relating to any extensions of credit or
          other  assets  of,  or any  deposits  with  or  other  liabilities  or
          commitments  of,  such  Bank  (or  its  Applicable   Lending  Office),
          including the Commitment of such Bank hereunder; or

               (iii)  shall  impose  on such  Bank  (or its  Applicable  Lending
          Office)  or  on  the  London  interbank  market  any  other  condition
          affecting  this  Agreement  or its Note or any of such  extensions  of
          credit or liabilities or commitments;

and the result of any of the  foregoing is to increase the cost to such Bank (or
its  Applicable  Lending  Office) of making,  Converting  into,  Continuing,  or
maintaining any Eurodollar  Loans or to reduce any sum received or receivable by
such Bank (or its  Applicable  Lending  Office) under this Agreement or its Note
with respect to any Eurodollar  Loans,  then the Borrower shall pay to such Bank
on demand such amount or amounts as will compensate such Bank for such increased
cost or reduction.  If any Bank  requests  compensation  by Borrower  under this
Section  14.1(a),  the  Borrower  may,  by notice  to such Bank  (with a copy to
Administrative  Agent),  suspend the

                                                                              62




obligation of such Bank to make or Continue  Eurodollar  Loans or to Convert all
or part of the Base Rate Loan owing to such Bank into  Eurodollar  Loans,  until
the event or condition  giving rise to such  request  ceases to be in effect (in
which case the provisions of Section 14.4 shall be applicable);  provided,  that
such  suspension  shall  not  affect  the  right  of such  Bank to  receive  the
compensation so requested.

          (b) If, after the date hereof, any Bank shall have determined that the
     adoption of any  applicable  law,  rule,  or regulation  regarding  capital
     adequacy or any change therein or in the  interpretation  or administration
     thereof by any Governmental  Authority,  central bank, or comparable agency
     charged with the interpretation or administration  thereof,  or any request
     or directive regarding capital adequacy (whether or not having the force of
     law) of any  such  Governmental  Authority,  central  bank,  or  comparable
     agency,  has or would have the effect of reducing the rate of return on the
     capital  of  such  Bank  or any  corporation  controlling  such  Bank  as a
     consequence  of such  Bank's  obligations  hereunder  to a level below that
     which  such  Bank or such  corporation  could  have  achieved  but for such
     adoption,  change,  request,  or directive  (taking into  consideration its
     policies with respect to capital  adequacy),  then,  from time to time upon
     demand,  Borrower shall pay to such Bank such additional  amount or amounts
     as will compensate such Bank for such reduction.

          (c) Each Bank shall promptly notify Borrower and Administrative  Agent
     of any event of which it has  knowledge,  occurring  after the date hereof,
     which will entitle such Bank to compensation  pursuant to this Section 14.1
     and  will  designate  a  different   Applicable   Lending  Office  if  such
     designation  will  avoid  the need for,  or  reduce  the  amount  of,  such
     compensation  and will not,  in the  judgment  of such Bank,  be  otherwise
     disadvantageous  to it. Any Bank claiming  compensation  under this Section
     14.1 shall furnish to Borrower and Administrative Agent a statement setting
     forth the  additional  amount or amounts to be paid to it  hereunder  which
     shall be conclusive in the absence of manifest error.  In determining  such
     amount, such Bank may use any reasonable averaging and attribution methods.

     SECTION 14.2  LIMITATION ON TYPE OF LOANS.  If on or prior to the first day
of any Interest Period for any Eurodollar Loan:

          (a)  Administrative  Agent determines  (which  determination  shall be
     conclusive) that by reason of circumstances  affecting the relevant market,
     adequate and reasonable  means do not exist for ascertaining the Eurodollar
     Rate for such Interest Period; or

          (b) Required Banks determine (which determination shall be conclusive)
     and notify  Administrative Agent that the Adjusted Eurodollar Rate will not
     adequately and fairly reflect the cost to Banks of funding Eurodollar Loans
     for such Interest Period;

then  Administrative  Agent shall give Borrower prompt notice thereof specifying
the relevant Type of Revolving Loans and the relevant amounts or periods, and so
long as such condition remains in effect,  Banks shall be under no obligation to
make additional  Revolving Loans of such Type,  Continue Revolving Loans of such
Type, or to Convert  Revolving  Loans of any other Type into Revolving  Loans of
such Type, and Borrower shall,  on the last day(s) of the then current  Interest
Period(s)  for the  outstanding  Revolving  Loans of the affected  Type,  either
prepay

                                                                              63



such  Revolving  Loans or Convert  such  Revolving  Loans into  another  Type of
Revolving Loan in accordance with the terms of this Agreement.

     SECTION  14.3  ILLEGALITY.  Notwithstanding  any  other  provision  of this
Agreement,  in the event that it becomes unlawful for any Bank or its Applicable
Lending Office to make, maintain, or fund Eurodollar Loans hereunder,  then such
Bank shall promptly notify Borrower  thereof and such Bank's  obligation to make
or Continue  Eurodollar Loans and to Convert other Types of Revolving Loans into
Eurodollar Loans shall be suspended until such time as such Bank may again make,
maintain,  and fund  Eurodollar  Loans (in which case the  provisions of Section
14.4 shall be applicable).

     SECTION 14.4 TREATMENT OF AFFECTED  LOANS. If the obligation of any Bank to
make particular  Eurodollar Loans or to Continue  Revolving Loans, or to Convert
Revolving  Loans of another Type into Revolving Loans of a particular Type shall
be suspended pursuant to Section 14.1 or Section 14.3 hereof (Revolving Loans of
such Type being herein called "AFFECTED LOANS" and such Type being herein called
the  "AFFECTED  TYPE"),  such  Bank's  Affected  Loans  shall  be  automatically
Converted  into  the  Base  Rate  Loan on the last  day(s)  of the then  current
Interest Period(s) for Affected Loans (or, in the case of a Conversion  required
by  Section  14.3  hereof,  on such  earlier  date as such Bank may  specify  to
Borrower with a copy to  Administrative  Agent) and,  unless and until such Bank
gives notice as provided below that the circumstances  specified in Section 14.1
or Section 14.3 hereof that gave rise to such Conversion no longer exist:

          (a) to the  extent  that  such  Bank's  Affected  Loans  have  been so
     Converted,  all payments and  prepayments of principal that would otherwise
     be applied to such Bank's  Affected  Loans shall be applied  instead to the
     Base Rate Loan; and

          (b) all Revolving  Loans that would  otherwise be made or Continued by
     such  Bank  as  Revolving  Loans  of the  Affected  Type  shall  be made or
     Continued instead as part of the Base Rate Loan, and all Revolving Loans of
     such Bank that would  otherwise be Converted  into  Revolving  Loans of the
     Affected Type shall be Converted  instead into (or shall remain) as part of
     the Base Rate Loan.

If such Bank gives notice to Borrower (with a copy to Administrative Agent) that
the  circumstances  specified  in Section  14.1 or Section 14.3 hereof that gave
rise to the  Conversion of such Bank's  Affected  Loans pursuant to this Section
14.4  no  longer  exist  (which  such  Bank  agrees  to do  promptly  upon  such
circumstances  ceasing to exist) at a time when Revolving  Loans of the Affected
Type made by other Banks are  outstanding,  such Bank's portion of the Base Rate
Loan  shall  be  automatically  Converted,  on the  first  day(s)  of  the  next
succeeding  Interest  Period(s)  for  such  outstanding  Revolving  Loans of the
Affected Type, to the extent necessary so that, after giving effect thereto, all
Revolving  Loans held by Banks holding  Revolving Loans of the Affected Type and
by such Bank are held pro rata (as to  principal  amounts,  Types  and  Interest
Periods) in accordance with their respective Commitments.

     SECTION 14.5 COMPENSATION. Upon the request of any Bank, Borrower shall pay
to such Bank such amount or amounts as shall be  sufficient  (in the  reasonable
opinion of

                                                                              64



such Bank) to compensate it for any loss,  cost, or expense  (including  loss of
anticipated profits) incurred by it as a result of:

          (a) any payment,  prepayment,  or Conversion of a Eurodollar  Loan for
     any  reason  (including,   without  limitation,  the  acceleration  of  the
     Revolving  Loan) on a date other than the last day of the  Interest  Period
     for such Loan; or

          (b) any failure by the  Borrower  for any reason  (including,  without
     limitation, the failure of any condition precedent specified in Article VII
     to be satisfied) to borrow, Convert,  Continue, or prepay a Eurodollar Loan
     on the date for such  Borrowing,  Conversion,  Continuation,  or prepayment
     specified in the relevant Request for Borrowing,  Notice of Continuation or
     Conversion,  or other notice of  Borrowing,  prepayment,  Continuation,  or
     Conversion under this Agreement.

     SECTION 14.6 TAXES.

          (a) Any and all payments by Borrower to or for the account of any Bank
     or  Administrative  Agent  hereunder or under any other Loan Paper shall be
     made free and clear of and  without  deduction  for any and all  present or
     future Taxes, duties, levies, imposts, deductions, charges or withholdings,
     and all liabilities  with respect thereto,  excluding,  in the case of each
     Bank and  Administrative  Agent, Taxes imposed on its income, and franchise
     Taxes imposed on it, by the jurisdiction  under the Laws of which such Bank
     (or its Applicable Lending Office) or Administrative Agent (as the case may
     be)  is  organized  or  any   political   subdivision   thereof  (all  such
     non-excluded  Taxes,  duties,   levies,   imposts,   deductions,   charges,
     withholdings, and liabilities being hereinafter referred to in this Section
     14.6 as  "NON-EXCLUDED  TAXES").  If  Borrower  shall be required by Law to
     deduct any  Non-Excluded  Taxes from or in respect of any sum payable under
     this Agreement or any other Loan Paper to any Bank or Administrative Agent,
     (i) the sum payable  shall be  increased  as necessary so that after making
     all required deductions (including deductions applicable to additional sums
     payable under this Section 14.6) such Bank or Administrative Agent receives
     an amount equal to the sum it would have  received  had no such  deductions
     been made, (ii) Borrower shall make such  deductions,  (iii) Borrower shall
     pay the full amount  deducted to the relevant  taxation  authority or other
     authority  in  accordance  with  applicable  Law, and (iv)  Borrower  shall
     furnish to  Administrative  Agent, at its address set forth on Schedule 2.1
     hereto,  the original or a certified copy of a receipt  evidencing  payment
     thereof.

          (b) In addition,  Borrower agrees to pay any and all present or future
     stamp or  documentary  Taxes and any  other  excise  or  property  Taxes or
     charges or similar  levies  which  arise from any  payment  made under this
     Agreement or any other Loan Paper or from the  execution or delivery of, or
     otherwise  with  respect  to,  this  Agreement  or  any  other  Loan  Paper
     (hereinafter referred to as "OTHER TAXES").

          (c) Borrower  agrees to indemnify each Bank and  Administrative  Agent
     for  the  full  amount  of  Taxes  and  Other  Taxes  (including,   without
     limitation,  any  Non-Excluded  Taxes or Other Taxes imposed or asserted by
     any  jurisdiction  on amounts payable under this Section 14.6) paid by such
     Bank or  Administrative  Agent  (as  the  case  may  be) and any  liability
     (including  penalties,  interest,  and expenses)  arising therefrom or with
     respect thereto.

                                                                              65




          (d) Each Bank organized  under the Laws of a jurisdiction  outside the
     United  States,  on or prior to the date of its  execution  and delivery of
     this  Agreement  in the case of each Bank listed on Schedule 2.1 hereto and
     on or prior to the  date on  which  it  becomes  a Bank in the case of each
     other Bank,  and from time to time  thereafter  if  requested in writing by
     Borrower  or  Administrative  Agent (but only so long as such Bank  remains
     lawfully able to do so), shall provide Borrower and  Administrative  Agent,
     at the time or times  prescribed  by  applicable  Law,  with such  properly
     completed  and executed  documentation  prescribed  by  applicable  Law (or
     reasonably  requested by Borrower) certifying that such Bank is entitled to
     benefits  under an income tax treaty to which the United  States is a party
     which  reduces  the rate of  withholding  tax on  payments  of  interest or
     certifying  that  the  income  receivable  pursuant  to this  Agreement  is
     effectively connected with the conduct of a trade or business in the United
     States, and certifying that such Bank is entitled to an exemption from or a
     reduced  rate of tax on payments  pursuant to this  Agreement or any of the
     other Loan Papers.

          (e) For any period with  respect to which a Bank has failed to provide
     Borrower and  Administrative  Agent with the  appropriate  form pursuant to
     Section 14.6(d) (unless such failure is due to a change in treaty,  law, or
     regulation  occurring subsequent to the date on which a form originally was
     required   to  be   provided),   such  Bank  shall  not  be   entitled   to
     indemnification  under Section  14.6(a) or Section  14.6(b) with respect to
     Non-Excluded Taxes imposed by the United States;  provided,  however,  that
     should a Bank,  which is otherwise exempt from or subject to a reduced rate
     of withholding  Tax,  become subject to  Non-Excluded  Taxes because of its
     failure  to deliver a form  required  hereunder,  Borrower  shall take such
     steps as such Bank shall reasonably  request to assist such Bank to recover
     such Non-Excluded Taxes.

          (f) If Borrower is  required to pay  additional  amounts to or for the
     account of any Bank  pursuant  to this  Section  14.6,  then such Bank will
     agree  to  use  reasonable  efforts  to  change  the  jurisdiction  of  its
     Applicable  Lending Office so as to eliminate or reduce any such additional
     payment which may thereafter accrue if such change, in the judgment of such
     Bank, is not otherwise disadvantageous to such Bank.

          (g)  Within  thirty  (30)  days  after  the  date  of any  payment  of
     Non-Excluded  Taxes,  Borrower  shall furnish to  Administrative  Agent the
     original or a certified copy of a receipt evidencing such payment.

          (h)  Without  prejudice  to the  survival  of any other  agreement  of
     Borrower hereunder, the agreements and obligations of Borrower contained in
     this Section 14.6 shall survive the  termination of the Commitments and the
     payment in full of the Notes.

     SECTION 14.7  DISCRETION OF BANKS AS TO MANNER OF FUNDING.  Notwithstanding
any provisions of this Agreement to the contrary, each Bank shall be entitled to
fund and maintain its funding of all or any part of its Commitment in any manner
it sees  fit,  it  being  understood,  however,  that for the  purposes  of this
Agreement  all  determinations  hereunder  shall  be made as if  such  Bank  had
actually  funded and maintained  each Eurodollar Loan during the Interest Period
for such  Eurodollar  Loan  through the  purchase of deposits  having a maturity
corresponding  to the last day of such  Interest  Period and bearing an interest
rate equal to the Adjusted Eurodollar Rate for such Interest Period.

                                                                              66

                                  MISCELLANEOUS

     SECTION 15.1 NOTICES. All notices, requests and other communications to any
party  hereunder shall be in writing  (including bank wire,  telecopy or similar
writing)  and shall be given,  if to  Administrative  Agent or any Bank,  at its
address or telecopier  number set forth on Schedule 2.1 hereto,  and if given to
Borrower,  at its address or telecopy  number set forth on the  signature  pages
hereof (or in either  case,  at such other  address or  telecopy  number as such
party may  hereafter  specify  for the  purpose  by notice to the other  parties
hereto). Each such notice, request or other communication shall be effective (a)
if given by telecopy,  when such telecopy is transmitted to the telecopy  number
specified  in this Section 15.1 and the  appropriate  answerback  is received or
receipt  is  otherwise  confirmed,  (b) if  given by mail,  three  (3)  Domestic

the  address   specified  in  this  Section  15.1;   provided  that  notices  to
Administrative  Agent  under  Article  III or Article IV shall not be  effective
until received.

     SECTION 15.2 NO WAIVERS. No failure or delay by Administrative Agent or any
Bank in exercising any right, power or privilege  hereunder or under any Note or
other  Loan Paper  shall  operate  as a waiver  thereof  nor shall any single or
partial  exercise  thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.  The rights and remedies herein
provided  shall be  cumulative  and not  exclusive  of any  rights  or  remedies
provided by Law or in any of the other Loan Papers.

     SECTION 15.3 EXPENSES; INDEMNIFICATION.

          (a) Borrower agrees to pay on demand all reasonable costs and expenses
     of each Agent (other than any Documentation  Agent or Syndication Agent) in
     connection  with  the  syndication,   preparation,   execution,   delivery,
     modification,  and amendment of this Agreement,  the other Loan Papers, and
     the  other  documents  to  be  delivered  hereunder,   including,   without
     limitation,  the reasonable fees and expenses of counsel for Administrative
     Agent with  respect  thereto and with  respect to  advising  Administrative
     Agent as to its rights and responsibilities under the Loan Papers. Borrower
     further  agrees to pay on demand all costs and  expenses of  Administrative
     Agent  and  Banks,  if  any  (including,  without  limitation,   reasonable
     attorneys' fees and expenses),  in connection with the enforcement (whether
     through negotiations,  legal proceedings,  or otherwise) of the Loan Papers
     and the other documents to be delivered hereunder.

          (B) BORROWER AGREES TO INDEMNIFY AND HOLD HARMLESS EACH AGENT AND EACH
     BANK AND EACH OF THEIR AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS,
     EMPLOYEES,  AGENTS,  AND ADVISORS (EACH,  AN "INDEMNIFIED  PARTY") FROM AND
     AGAINST  ANY AND ALL  CLAIMS,  DAMAGES,  LOSSES,  LIABILITIES,  COSTS,  AND
     EXPENSES (INCLUDING,  WITHOUT LIMITATION,  REASONABLE ATTORNEYS' FEES) THAT
     MAY BE INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN
     EACH CASE ARISING OUT OF OR IN CONNECTION  WITH OR BY REASON OF (INCLUDING,
     WITHOUT LIMITATION,  IN

                                                                              67




     CONNECTION WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION
     OF  DEFENSE  IN  CONNECTION   THEREWITH)  THE  LOAN  PAPERS,   ANY  OF  THE
     TRANSACTIONS  CONTEMPLATED  HEREIN  OR THE  ACTUAL OR  PROPOSED  USE OF THE
     PROCEEDS OF THE REVOLVING LOAN (INCLUDING ANY OF THE FOREGOING ARISING FROM
     THE NEGLIGENCE OF THE INDEMNIFIED PARTY),  EXCEPT TO THE EXTENT SUCH CLAIM,
     DAMAGE,   LOSS,   LIABILITY,   COST,  OR  EXPENSE  IS  FOUND  IN  A  FINAL,
     NON-APPEALABLE  JUDGMENT  BY A  COURT  OF  COMPETENT  JURISDICTION  TO HAVE
     RESULTED  FROM  SUCH  INDEMNIFIED   PARTY'S  GROSS  NEGLIGENCE  OR  WILLFUL
     MISCONDUCT. IN THE CASE OF AN INVESTIGATION, LITIGATION OR OTHER PROCEEDING
     TO WHICH THE INDEMNITY IN THIS SECTION 15.3 APPLIES,  SUCH INDEMNITY  SHALL
     BE EFFECTIVE WHETHER OR NOT SUCH INVESTIGATION, LITIGATION OR PROCEEDING IS
     BROUGHT BY CREDIT PARTIES,  ITS DIRECTORS,  SHAREHOLDERS OR CREDITORS OR AN
     INDEMNIFIED PARTY OR ANY OTHER PERSON OR ANY INDEMNIFIED PARTY IS OTHERWISE
     A PARTY THERETO AND WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE
     CONSUMMATED. BORROWER AGREES NOT TO ASSERT ANY CLAIM AGAINST ANY AGENT, ANY
     BANK,  ANY OF  THEIR  AFFILIATES,  OR ANY OF  THEIR  RESPECTIVE  DIRECTORS,
     OFFICERS,  EMPLOYEES,  ATTORNEYS,  AGENTS,  AND ADVISERS,  ON ANY THEORY OF
     LIABILITY,  FOR  SPECIAL,  INDIRECT,  CONSEQUENTIAL,  OR  PUNITIVE  DAMAGES
     ARISING  OUT OF OR  OTHERWISE  RELATING  TO  THE  LOAN  PAPERS,  ANY OF THE
     TRANSACTIONS  CONTEMPLATED  HEREIN  OR THE  ACTUAL OR  PROPOSED  USE OF THE
     PROCEEDS OF THE REVOLVING LOAN.

          (c)  Without  prejudice  to the  survival  of any other  agreement  of
     Borrower hereunder, the agreements and obligations of Borrower contained in
     this Section 15.3 shall survive the payment in full of the  Revolving  Loan
     and all other amounts payable under this Agreement.

     SECTION 15.4 RIGHT OF SET-OFF; ADJUSTMENTS.

          (a) Upon the  occurrence  and during the  continuance  of any Event of
     Default, each Bank (and each of its Affiliates) is hereby authorized at any
     time and from time to time, to the fullest extent  permitted by Law, to set
     off and apply any and all  deposits  (general or  special,  time or demand,
     provisional or final) at any time held and other  indebtedness  at any time
     owing by such Bank (or any of its  Affiliates)  to or for the credit or the
     account  of any  Credit  Party  against  any  and  all of the  Obligations,
     irrespective  of whether  such Bank  shall have made any demand  under this
     Agreement  or Note  held by  such  and  although  such  obligations  may be
     unmatured.  Each Bank agrees  promptly to notify the affected  Credit Party
     after  any  such  set-off  and  application  made by such  Bank;  provided,
     however, that the failure to give such notice shall not affect the validity
     of such set-off and application. The rights of each Bank under this Section
     15.4 are in  addition  to other  rights and  remedies  (including,  without
     limitation,  other rights of set-off)  that such Bank may have.

                                                                              68



          (b) If any Bank (a  "BENEFITTED  BANK")  shall at any time receive any
     payment of all or part of the amounts owing to it, or interest thereon,  or
     receive  any  collateral  in  respect  thereof   (whether   voluntarily  or
     involuntarily,  by set-off, or otherwise), in a greater proportion than any
     such  payment to or  collateral  received  by any other  Bank,  if any,  in
     respect of such other Bank's amounts owing to it, or interest thereon, such
     benefitted   Bank  shall   purchase   for  cash  from  the  other  Banks  a
     participating  interest in such portion of each such other  Bank's  amounts
     owing to it, or shall  provide  such other  Banks with the  benefits of any
     such collateral,  or the proceeds  thereof,  as shall be necessary to cause
     such  benefitted  Bank to share the  excess  payment  or  benefits  of such
     collateral  or proceeds  ratably with each other Bank;  provided,  however,
     that if all or any portion of such excess payment or benefits is thereafter
     recovered from such benefitted Bank, such purchase shall be rescinded,  and
     the purchase price and benefits  returned,  to the extent of such recovery,
     but  without  interest.  Borrower  agrees  that  any Bank so  purchasing  a
     participation from a Bank pursuant to this Section 15.4 may, to the fullest
     extent permitted by Law,  exercise all of its rights of payment  (including
     the right of set-off)  with  respect to such  participation  as fully as if
     such  Person  were the direct  creditor  of  Borrower in the amount of such
     participation.

     SECTION 15.5 AMENDMENTS AND WAIVERS.  Any provision of this Agreement,  the
Notes or any other Loan  Paper may be  amended  or waived if, but only if,  such
amendment or waiver is in writing and is signed by Borrower  and Required  Banks
(and, if the rights or duties of any Agent are affected thereby, by such Agent);
provided that no such amendment or waiver shall, unless signed by all Banks, (a)
increase  the  Commitment  of any Bank,  (b) reduce the  principal of or rate of
interest on any Revolving Loan or any fees or other amounts payable hereunder or
for  termination  of any  Commitment,  (c)  change the  percentage  of the Total
Commitment,  or the number of Banks which shall be required  for Banks or any of
them to take any action under this  Section 15.5 or any other  provision of this
Agreement, (d) extend the due date for, or forgive any principal, interest, fees
or reimbursement  obligations due hereunder,  (e) release any material guarantor
or other material party liable for all or any part of the Obligations or release
any material  part of the  collateral  for the  Obligations  or any part thereof
other than releases required pursuant to sales of collateral which are expressly
permitted by Section 10.5 hereof,  or (f) amend or modify any of the  provisions
of Article V hereof or the definitions of any terms defined therein.

     SECTION 15.6 SURVIVAL.  All representations,  warranties and covenants made
by any Credit Party herein or in any certificate or other  instrument  delivered
by it or in its behalf  under the Loan Papers shall be  considered  to have been
relied upon by Banks and shall survive the delivery to Banks of such Loan Papers
or the extension of the Revolving Loan (or any part thereof),  regardless of any
investigation  made by or on behalf of Banks. The indemnity  provided in Section
15.3(b)  herein shall  survive the  repayment of all credit  advances  hereunder
and/or the  discharge or release of any Lien  granted  hereunder or in any other
Loan Paper, contract or agreement between Borrower or any other Credit Party and
any Agent or any Bank.

     SECTION 15.7 LIMITATION ON INTEREST.  Regardless of any provision contained
in the Loan Papers, Banks shall never be entitled to receive, collect, or apply,
as interest on the Revolving  Loan,  any amount in excess of the Maximum  Lawful
Rate, and in the event any Bank ever  receives,  collects or applies as interest
any such excess,  such amount which would be deemed excessive  interest shall be
deemed a partial  prepayment of principal and treated

                                                                              69



hereunder as such;  and if the  Revolving  Loan is paid in full,  any  remaining
excess shall  promptly be paid to Borrower.  In  determining  whether or not the
interest  paid or payable  under any  specific  contingency  exceeds the Maximum
Lawful Rate,  Borrower and Banks shall, to the extent permitted under applicable
Law, (a) characterize any  non-principal  payment as an expense,  fee or premium
rather than as  interest,  (b)  exclude  voluntary  prepayments  and the effects
thereof and (c)  amortize,  prorate,  allocate and spread,  in equal parts,  the
total  amount of the interest  throughout  the entire  contemplated  term of the
Notes,  so that the  interest  rate is the Maximum  Lawful Rate  throughout  the
entire  term of the  Notes;  provided,  however,  that if the  unpaid  principal
balance  thereof  is paid  and  performed  in full  prior to the end of the full
contemplated term thereof, and if the interest received for the actual period of
existence  thereof  exceeds  the Maximum  Lawful  Rate,  Banks  shall  refund to
Borrower  the amount of such  excess  and,  in such  event,  Banks  shall not be
subject to any penalties  provided by any Laws for  contracting  for,  charging,
taking, reserving or receiving interest in excess of the Maximum Lawful Rate.

     SECTION 15.8  INVALID  PROVISIONS.  If any  provision of the Loan Papers is
held to be  illegal,  invalid,  or  unenforceable  under  present or future Laws
effective during the term thereof, such provision shall be fully severable,  the
Loan Papers shall be  construed  and enforced as if such  illegal,  invalid,  or
unenforceable  provision had never  comprised a part thereof,  and the remaining
provisions  thereof  shall  remain  in full  force and  effect  and shall not be
affected by the illegal, invalid, or unenforceable provision or by its severance
therefrom.  Furthermore,  in lieu of such  illegal,  invalid,  or  unenforceable
provision  there  shall be added  automatically  as a part of the Loan  Papers a
provision  as  similar  in  terms to such  illegal,  invalid,  or  unenforceable
provision as may be possible and be legal, valid and enforceable.

     SECTION 15.9 WAIVER OF CONSUMER CREDIT LAWS. Pursuant to Chapter 346 of the
Texas Finance Code, as amended,  Borrower agrees that such Chapter 346 shall not
govern or in any manner apply to the Revolving Loan.

     SECTION 15.10 ASSIGNMENTS AND PARTICIPATIONS.

          (a)  SUCCESSORS  AND  ASSIGNS.  The terms and  provisions  of the Loan
     Papers shall be binding upon and inure to the benefit of Borrower and Banks
     and their respective  successors and assigns permitted hereby,  except that
     (i) Borrower  shall not have the right to assign its rights or  obligations
     under the Loan Papers without the prior written  consent of each Bank, (ii)
     any  assignment  by any  Bank  must  be  made in  compliance  with  Section
     15.10(c),  and  (iii)  any  transfer  by  participation  must  be  made  in
     compliance with Section 15.10(b).  Any attempted  assignment or transfer by
     any party not made in compliance  with this Section  15.10(a) shall be null
     and void,  unless  such  attempted  assignment  or transfer is treated as a
     participation  in  accordance  with Section  15.10(b).  The parties to this
     Agreement  acknowledge  that clause (ii) of this Section  15.10(a)  relates
     only to absolute  assignments  and this Section  15.10(a) does not prohibit
     assignments creating security interests, including, without limitation, (x)
     any pledge or  assignment  by any Bank of all or any  portion of its rights
     under this  Agreement and any Note to a Federal  Reserve Bank or (y) in the
     case of a Bank  which is a Fund,  any  pledge or  assignment  of all or any
     portion of its rights under this  Agreement  and any Note to its trustee in
     support of its obligations to its trustee; provided,  however, that no such
     pledge or  assignment  creating  a  security  interest  shall  release  the
     transferor Bank from its obligations hereunder unless and until

                                                                              70



     the parties thereto have complied with the provisions of Section  15.10(c).
     Administrative  Agent may treat the Person which made any Revolving Loan or
     which holds any Note as the owner  thereof for all purposes  hereof  unless
     and until such Person complies with Section  15.10(c);  provided,  however,
     that Administrative  Agent may in its discretion (but shall not be required
     to) follow  instructions  from the Person which made any Revolving  Loan or
     which holds any Note to direct payments  relating to such Revolving Loan or
     Note to another Person. Any assignee of the rights to any Revolving Loan or
     any Note agrees by  acceptance  of such  assignment  to be bound by all the
     terms and provisions of the Loan Papers. Any request,  authority or consent
     of any  Person,  who at the time of making  such  request  or  giving  such
     authority  or  consent  is the owner of the  rights to any  Revolving  Loan
     (whether  or not a Note has been  issued  in  evidence  thereof),  shall be
     conclusive and binding on any  subsequent  holder or assignee of the rights
     to such Revolving Loan.

          (b) PARTICIPATIONS.

               (i) Any Bank may at any time  sell to one or more  banks or other
          entities  ("PARTICIPANTS")  participating  interests in any  Revolving
          Loan owing to such Bank, any Note held by such Bank, any Commitment of
          such Bank or any other interest of such Bank under the Loan Papers. In
          the event of any such sale by a Bank of  participating  interests to a
          Participant,  such  Bank's  obligations  under the Loan  Papers  shall
          remain  unchanged,  such Bank shall remain solely  responsible  to the
          other parties  hereto for the  performance of such  obligations,  such
          Bank shall remain the owner of its  Revolving  Loans and the holder of
          any Note issued to it in evidence  thereof for all purposes  under the
          Loan  Papers,  all amounts  payable by Borrower  under this  Agreement
          shall be  determined  as if such Bank had not sold such  participating
          interests,  and Borrower and  Administrative  Agent shall  continue to
          deal solely and directly with such Bank in connection with such Bank's
          rights and obligations under the Loan Papers.

               (ii) Each Bank shall  retain the sole right to  approve,  without
          the consent of any Participant, any amendment,  modification or waiver
          of  any  provision  of the  Loan  Papers  other  than  any  amendment,
          modification   or  waiver  with  respect  to  any  Revolving  Loan  or
          Commitment  in which such  Participant  has an  interest  which  would
          require  consent of all of the Banks  pursuant to the terms of Section
          15.5 or of any other Loan Paper.

               (iii) Borrower  agrees that each  Participant  shall be deemed to
          have the right of setoff  provided  in Section  15.4 in respect of its
          participating  interest in amounts  owing under the Loan Papers to the
          same extent as if the amount of its participating  interest were owing
          directly to it as a Bank under the Loan  Papers;  provided,  that each
          Bank shall  retain the right of setoff  provided in Section  15.4 with
          respect  to  the  amount  of  participating  interests  sold  to  each
          Participant.  Banks  agree to share  with each  Participant,  and each
          Participant,  by  exercising  the right of setoff  provided in Section
          15.4,  agrees to share with each Bank, any amount received pursuant to
          the  exercise  of its right of  setoff,  such  amounts to be shared in
          accordance  with  Section  15.4  as if each  Participant  were a Bank.
          Borrower further agrees that each Participant shall be entitled to the
          yield  protection  provisions  contained  in  Article  XIV to the same
          extent  as if it  were  a  Bank  and  had  acquired  its  interest  by
          assignment  pursuant  to  Section  15.10(c);

                                                                              71




          provided,  that (A) a Participant shall not be entitled to receive any
          greater  payment  under  Article  XIV  than  the  Bank  who  sold  the
          participating  interest to such Participant would have received had it
          retained  such  interest for its own account,  unless the sale of such
          interest to such Participant is made with the prior written consent of
          Borrower,  and (B) any Participant not incorporated  under the laws of
          the United  States of America  or any State  thereof  agrees to comply
          with the provisions of Section 14.6 to the same extent as if it were a
          Bank.

          (c) ASSIGNMENTS.

               (i) Any Bank may at any time assign to one or more banks or other
          entities  ("PURCHASERS") all or any part of its rights and obligations
          under the Loan Papers.  The parties to such  assignment  shall execute
          and deliver an Assignment and Acceptance  Agreement (herein so called)
          which shall be substantially in the form of Exhibit K or in such other
          form as may be agreed to by the parties thereto.  Each such assignment
          with  respect to a Purchaser  which is not a Bank or an Affiliate of a
          Bank or an  Approved  Fund shall  either be in an amount  equal to the
          entire applicable Commitment and Revolving Loans of the assigning Bank
          or  (unless  each  of  Borrower  and  Administrative  Agent  otherwise
          consents)  be in an  aggregate  amount not less than  $5,000,000.  The
          amount  of  the  assignment  shall  be  based  on  the  Commitment  or
          outstanding  Revolving  Loans (if the Commitment has been  terminated)
          subject  to  the  assignment,  determined  as  of  the  date  of  such
          assignment or as of the "Effective  Date," if the "Effective  Date" is
          specified in the Assignment and Acceptance Agreement.

               (ii)  The  consent  of  Borrower  shall be  required  prior to an
          assignment becoming effective unless Purchaser is a Bank, an Affiliate
          of a Bank or an Approved  Fund,  provided that the consent of Borrower
          shall not be required if a Default has occurred and is continuing. The
          consent  of  Administrative  Agent  shall  be  required  prior  to  an
          assignment  becoming  effective  unless the  Purchaser  is a Bank,  an
          Affiliate  of a Bank or an  Approved  Fund.  The  consent of Letter of
          Credit Issuer shall be required prior to an assignment of a Commitment
          becoming  effective unless Purchaser is a Bank, an Affiliate of a Bank
          or  an  Approved  Fund.  Any  consent   required  under  this  Section
          15.10(c)(ii) shall not be unreasonably  withheld or delayed.

               (iii) Upon (A) delivery to Administrative  Agent of an Assignment
          and  Acceptance  Agreement,  together  with any  consents  required by
          Section  15.10(c)(i)  and (ii),  and (B)  payment  of a $3,500  fee to
          Administrative  Agent for processing such assignment  (unless such fee
          is waived by  Administrative  Agent),  such  assignment  shall  become
          effective  on the  effective  date  specified in such  Assignment  and
          Acceptance  Agreement.  On  and  after  the  effective  date  of  such
          assignment,  such Purchaser  shall for all purposes be a Bank party to
          this  Agreement  and any other Loan Paper  executed by or on behalf of
          Banks and shall have all the rights  and  obligations  of a Bank under
          the Loan  Papers,  to the same extent as if it were an original  party
          thereto, and the transferor Bank shall be released with respect to the
          Commitment and Revolving Loans assigned to such Purchaser  without any
          further consent or action by Borrower,  Banks or Administrative Agent.
          In the case of an  assignment  covering  all of the  assigning  Bank's
          rights and obligations under this Agreement,  such Bank shall cease to
          be a Bank  hereunder but shall

                                                                              72



          continue  to be  entitled to the  benefits  of, and subject to,  those
          provisions  of this  Agreement and the other Loan Papers which survive
          payment  of  the   Obligations   and  termination  of  the  applicable
          agreement.  Any  assignment  or  transfer  by  a  Bank  of  rights  or
          obligations  under  this  Agreement  that  does not  comply  with this
          Section  15.10(c) shall be treated for purposes of this Agreement as a
          sale by such Bank of a participation in such rights and obligations in
          accordance  with  Section  15.10(b).  Upon  the  consummation  of  any
          assignment  to a Purchaser  pursuant  to this  Section  15.10(c),  the
          transferor  Bank,   Administrative   Agent  and  Borrower  shall  make
          appropriate  arrangements  so  that  new  Notes  or,  as  appropriate,
          replacement Notes are issued to such transferor Bank and new Notes or,
          as appropriate,  replacement  Notes, are issued to such Purchaser,  in
          each  case  in   principal   amounts   reflecting   their   respective
          Commitments, as adjusted pursuant to such assignment.

               (iv)  Administrative  Agent, acting solely for this purpose as an
          agent of  Borrower,  shall  maintain at one of its offices in Chicago,

          Agreement  delivered to it and a register for the  recordation  of the
          names  and  addresses  of the  Banks,  and  the  Commitments  of,  and
          principal  amounts of the Revolving Loans owing to, each Bank pursuant
          to the terms hereof from time to time (the "REGISTER"). The entries in
          the Register shall be conclusive,  and Borrower,  Administrative Agent
          and Banks may treat each Person whose name is recorded in the Register
          pursuant to the terms hereof as a Bank  hereunder  for all purposes of
          this Agreement,  notwithstanding  notice to the contrary. The Register
          shall be available  for  inspection  by Borrower and any Bank,  at any
          reasonable time and from time to time upon reasonable prior notice.

          (d)  DISSEMINATION  OF INFORMATION.  Borrower  authorizes each Bank to
     disclose to any  Participant or Purchaser or any other Person  acquiring an
     interest in the Loan Papers by operation of law (each a  "TRANSFEREE")  and
     any  prospective   Transferee  any  and  all  information  in  such  Bank's
     possession   concerning   the   creditworthiness   of   Borrower   and  its
     Subsidiaries,  including,  without limitation, any information contained in
     any financial  reports;  provided,  that,  each  Transferee and prospective
     Transferee agrees to be bound by Section 15.17 of this Agreement.

     (e) TAX TREATMENT.  If any interest in any Loan Paper is transferred to any
Transferee which is not incorporated  under the laws of the United States or any
State thereof,  the transferor  Bank shall cause such  Transferee,  concurrently
with the  effectiveness  of such  transfer,  to comply  with the  provisions  of
Section 14.6(d).(f)

     SECTION  15.11  TEXAS  LAW.  THIS  AGREEMENT,  EACH NOTE AND THE OTHER LOAN
PAPERS  HAVE  BEEN  EXECUTED  AND  DELIVERED  IN THE STATE OF TEXAS AND SHALL BE
CONSTRUED IN ACCORDANCE  WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND
THE LAWS OF THE UNITED STATES OF AMERICA,  EXCEPT TO THE EXTENT THAT THE LAWS OF
ANY STATE IN WHICH ANY  PROPERTY  INTENDED AS SECURITY  FOR THE  OBLIGATIONS  IS
LOCATED NECESSARILY GOVERN (A) THE PERFECTION AND PRIORITY OF THE LIENS IN FAVOR
OF  ADMINISTRATIVE  AGENT AND BANKS WITH RESPECT TO SUCH

                                                                              73



PROPERTY,  AND (B) THE EXERCISE OF ANY  REMEDIES  (INCLUDING  FORECLOSURE)  WITH
RESPECT TO SUCH  PROPERTY.

     SECTION 15.12 CONSENT TO JURISDICTION; WAIVER OF IMMUNITIES.

          (a) Borrower  hereby  irrevocably  submits to the  jurisdiction of any
     Texas State or Federal court sitting in the Northern District of Texas over
     any action or  proceeding  arising out of or relating to this  Agreement or
     any other Loan Papers,  and  Borrower  hereby  irrevocably  agrees that all
     claims in respect of such action or proceeding  may be heard and determined
     in  such  Texas  State  or  Federal  court.  As  an  alternative,  Borrower
     irrevocably  consents  to the  service  of any and all  process in any such
     action or proceeding by the mailing (which shall be by registered  mail) of
     copies of such  process to such Person at its address  specified in Section
     15.1.  Borrower  agrees  that a  final  judgment  on  any  such  action  or
     proceeding  shall be conclusive and may be enforced in other  jurisdictions
     by suit on the judgment or in any other manner provided by Law.

          (b) Nothing in this  Section  15.12 shall affect any right of Banks to
     serve  legal  process in any other  manner  permitted  by Law or affect the
     right of any Bank to bring any  action or  proceeding  against  any  Credit
     Party or their properties in the courts of any other jurisdictions.

          (c) To the extent  that  Borrower  has or  hereafter  may  acquire any
     immunity from  jurisdiction of any court or from any legal process (whether
     through service or notice, attachment prior to judgment,  attachment in aid
     of  execution,  execution  or  otherwise)  with  respect  to  itself or its
     property, such Person hereby irrevocably waives such immunity in respect of
     its obligations under this Agreement and the other Loan Papers.

     SECTION 15.13 COUNTERPARTS;  EFFECTIVENESS. This Agreement may be signed in
any number of  counterparts,  each of which shall be an original,  with the same
effect as if the  signatures  thereto and hereto were upon the same  instrument.
Subject  to the terms  and  conditions  herein  set  forth  (including,  without
limitation,  the execution and delivery of the  Certificate  of  Effectiveness),
this  Agreement  shall become  effective  when  Administrative  Agent shall have
received counterparts hereof signed by all of the parties hereto or, in the case
of any Bank as to which an executed  counterpart  shall not have been  received,
Administrative   Agent  shall  have  received   telegraphic   or  other  written
confirmation from such Bank of execution of a counterpart hereof by such Bank.

     SECTION  15.14 NO THIRD  PARTY  BENEFICIARIES.  Except  for the  provisions
hereof  inuring to the  benefit of Agents not a party to this  Agreement,  it is
expressly  intended  that there  shall be no third  party  beneficiaries  of the
covenants, agreements, representations or warranties herein contained other than

     SECTION 15.17 CONFIDENTIALITY.  Administrative Agent and each Bank (each, a
"LENDING PARTY") agrees to keep  confidential any information  furnished or made
available  to  it  by  Borrower  pursuant  to  this  Agreement  that  is  marked
