     (a)      The  Borrower  may  from  time  to  time  prepay, without  penalty
or premium, all outstanding  Floating  Rate Advances or, in an  aggregate amount
of $1,000,000 or a higher integral  multiple of $500,000 (or, in the case of any
prepayment of an  Advance made to repay a Swing  Line Loan, in such other amount
as is necessary to repay such Advance in full),  any portion of the  outstanding
Floating  Rate  Advances  upon  notice  to  the  Administrative  Agent not later
than  11:00 a.m. (Chicago time) on the date of prepayment. The Borrower may from

                                      -19-

time to time prepay,  without  penalty or premium,  all  outstanding  Eurodollar
Advances or, in an aggregate amount of $1,000,000 or a higher integral  multiple
thereof, any portion of the outstanding  Eurodollar Advances upon three Business
Days' prior  notice to the  Administrative  Agent.  The Borrower may at any time
pay,  without penalty or premium,  all  outstanding  Swing Line Loans or, in the
amount of $100,000 or a higher  integral  multiple  thereof,  any portion of the
outstanding  Swing Line Loans, with notice to the  Administrative  Agent and the
Swing Line Lender by 11:00 a.m. (Chicago time) on the date of repayment.

     (b)      On any date on  which the Aggregate Commitment is reduced pursuant
to Section  2.8, the Borrower shall make a prepayment of Loans in the amount, if
any,  by which the Total  Outstandings  exceed the  Aggregate  Commitment  as so
reduced. Any partial prepayment pursuant to this subsection (b) shall be applied
to such Loans as the Borrower  may direct or, in the absence of such  direction,
as the Administrative Agent may reasonably determine.

     (c)      Any  prepayment of a Eurodollar Loan on  a day other than the last
day of an Interest Period therefor shall be subject to Section 3.4.

     2.10     Interest  Rates,  etc.   Each Floating  Rate  Advance  shall  bear
interest on the  outstanding  principal  amount  thereof,  for each day from and
including  the date  such  Advance  is made or is  converted  from a  Eurodollar
Advance into a Floating  Rate Advance  pursuant to Section 2.5, to but excluding
the  date it is paid or is  converted  into a  Eurodollar  Advance  pursuant  to
Section 2.5, at a rate per annum equal to the Floating  Rate for such day.  Each
Swing Line Loan shall bear interest on the outstanding principal amount thereof,
for each day from and  including  the day such  Swing  Line  Loan is made to but
excluding the date it is paid,  at a rate per annum equal to the Alternate  Base
Rate for such  day or such  other  rate as may be  mutually  agreed  upon by the
Borrower  and the Swing Line  Lender from time to time;  provided  that the rate
applicable  to any  Swing  Line  Loan on any day  shall  not be  less  than  the
Eurodollar  Rate which would be applicable to a Eurodollar Loan with a one-month
Interest Period beginning on such day (or on the immediately  preceding Business
Day).  Changes in the rate of interest on that portion of any Advance maintained
as a Floating  Rate Advance and on any Swing Line Loan  bearing  interest at the
Alternate  Base Rate will take  effect  simultaneously  with each  change in the
Alternate  Base  Rate.  Each  Eurodollar  Advance  shall  bear  interest  on the
outstanding  principal  amount  thereof from and including the first day of each
Interest Period  applicable  thereto to (but not including) the last day of such
Interest Period at the interest rate determined by the  Administrative  Agent as
applicable to such Eurodollar Advance based upon the Borrower's selections under
Sections 2.4 and 2.5 and otherwise in accordance with the terms hereof.

     2.11     Rates  Applicable After  Default.  Notwithstanding anything to the
contrary  herein,  during the continuance of a Default or Unmatured  Default the
Required  Lenders may, at their option,  by notice to the Borrower (which notice
may be  revoked  at the  option  of the  Required  Lenders  notwithstanding  any
provision ofSection 8.2 requiring unanimous consent of the Lenders to changes in
interest  rates),  declare  that no Advance  may be made as,  converted  into or
continued  as a  Eurodollar  Advance.  During the  continuance  of a Default the
Required  Lenders

                                      -20-

may, at their option,  by notice to the Borrower (which notice may be revoked at
the option of the Required Lenders  notwithstanding any provision of Section 8.2
requiring  unanimous  consent of the  Lenders to  changes  in  interest  rates),
declare that (i) each  Eurodollar  Advance shall bear interest for the remainder
of the  applicable  Interest  Period at the rate  otherwise  applicable  to such
Interest  Period plus 2% per annum and (ii) each  Floating Rate Advance and each
Swing Line Loan shall bear  interest at a rate per annum  equal to the  Floating
Rate in effect from time to time plus 2% per annum,  provided  that,  during the
continuance  of a Default under Section 7.1.6 or 7.1.7,  the interest  rates set
forth in clauses  (i) and (ii) above shall be  applicable  to all  Advances  and
Swing  Line  Loans   without  any   election  or  action  on  the  part  of  the
Administrative Agent or any Lender.

     2.12     Maturity.  Any  outstanding Advances and Swing  Line Loans and all
other  accrued and unpaid  Obligations  shall be paid in full by the Borrower on
the scheduled  Termination  Date or such earlier date required by Section 2.9 or
Section 8.1.

     2.13     Method of Payment. All payments of the Obligations hereunder shall
be made, without setoff,  deduction,  or counterclaim,  in immediately available
funds  to  the  Administrative  Agent  at  the  Administrative  Agent's  address
specified pursuant to Article XIII, or at any other Lending  Installation of the
Administrative  Agent  specified in writing by the  Administrative  Agent to the
Borrower,  by noon (local  time) on the date when due and  (except for  payments
with  respect  to  Swing  Line  Loans  or  as  otherwise  specifically  required
hereunder)  shall be  applied  ratably  by the  Administrative  Agent  among the
Lenders in  accordance  with their  respective  Pro Rata  Shares.  Each  payment
delivered  to the  Administrative  Agent for the account of any Lender  shall be
delivered promptly by the  Administrative  Agent to such Lender in the same type
of  funds  that the  Administrative  Agent  received  at its  address  specified
pursuant to Article  XIII or at any Lending  Installation  specified in a notice
received by the Administrative  Agent from such Lender. The Administrative Agent
is hereby authorized to charge the account of the Borrower  maintained with Bank
One  for  each  payment  of  principal,  interest  and  fees as it  becomes  due
hereunder.

     2.14     Noteless  Agreement;  Evidence  of  Indebtedness.  (i) Each Lender
shall  maintain  in  accordance  with its usual  practice an account or accounts
evidencing the  indebtedness of the Borrower to such Lender  resulting from each
Loan made by such Lender from time to time,  including  the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

     (ii)  The  Administrative  Agent  shall also  maintain accounts in which it
will record (a) the amount of each Loan made  hereunder,  the Type  thereof and,
if applicable,  each Interest  Period  with respect  thereto,  (b) the amount of
any principal  or interest  due and  payable or to become due and  payable  from
the Borrower to each Lender  hereunder and (c) the amount of any sum received by
the Administrative Agent hereunder from  the  Borrower and each  Lender's  share
thereof.
                                     -21-

     (iii)    The  entries  maintained  in the  accounts maintained pursuant  to
subsections  (i) and (ii) above shall be prima facie  evidence of the  existence
and amounts of the Obligations  therein  recorded;  provided that the failure of
the  Administrative  Agent or any Lender to maintain  such accounts or any error
therein shall not in any manner  affect the  obligation of the Borrower to repay
the Obligations in accordance with their terms.

     (iv)     Any Lender may request that its  Loans be evidenced by a Note.  In
such event,  the Borrower  shall  prepare,  execute and deliver to such Lender a
Note payable to the order of such  Lender.  Thereafter,  the Loans  evidenced by
such  Note  and  interest  thereon  shall  at  all  times  (including  after any
assignment  pursuant  to  Section  12.3)  be  represented  by  one or more Notes
payable to the order of the payee  named  therein or any  assignee  pursuant  to
Section 12.3, except to the extent that any such Lender or assignee subsequently
returns any such Note for  cancellation and  requests that such Loans once again
be evidenced as described in subsections (i) and (ii) above.

     2.15     Telephonic Notices. The Borrower hereby authorizes the Lenders and
the Administrative Agent to extend,  convert or continue Advances and Swing Line
Loans, to effect  selections of Types of Advances and to transfer funds based on
telephonic notices made by any person or persons the Administrative Agent or any
Lender in good faith  believes to be acting on behalf of the Borrower,  it being
understood that the foregoing  authorization  is specifically  intended to allow
Borrowing  Notices,  Swing Line  Borrowing  Notices and  Conversion/Continuation
Notices to be given  telephonically.  The Borrower agrees to deliver promptly to
the  Administrative  Agent  a  written  confirmation,  if such  confirmation  is
requested by the  Administrative  Agent or any Lender, of each telephonic notice
signed by an  Authorized  Officer.  If the written  confirmation  differs in any
material  respect  from the  action  taken by the  Administrative  Agent and the
Lenders,  the records of the  Administrative  Agent and the Lenders shall govern
absent manifest error.

     2.16     Interest Payment Dates;  Interest and Fee Basis.  Interest accrued
on each  Floating  Rate  Advance  and Swing  Line Loan  shall be payable on each
Payment Date, on any date on which such Floating Rate Advance or Swing Line Loan
is prepaid, whether due to acceleration or otherwise, and at maturity.  Interest
accrued  on each  Eurodollar  Advance  shall be  payable on the last day of each
applicable  Interest  Period,  on any date on which  such  Advance  is  prepaid,
whether by  acceleration  or  otherwise,  or is converted  into a Floating  Rate
Advance, and at maturity.  Interest accrued on each Eurodollar Advance having an
Interest  Period  longer than three months shall also be payable on the last day
of  each  three-month  interval  during  such  Interest  Period.   Interest  and
commitment  fees shall be  calculated  for actual days elapsed on the basis of a
360-day  year,  except  that  interest  accruing  at the  Prime  Rate  shall  be
calculated  for actual days  elapsed on the basis of a 365, or when  appropriate
366, day year.  Interest  shall  be  payable  for  the day an Advance or a Swing
Line  Loan is made  but not for the day of any  payment  on the  amount  paid if
payment is received  prior to noon (local time) at the place of payment.  If any
payment of  principal  of or  interest  on an Advance or a Swing Line Loan shall
become due on a day which is not a Business  Day,  such payment shall be made on
the next

                                      -22-

succeeding  Business Day and, in the case of a principal payment, such extension
of time shall be included in computing interest in connection with such payment.

     2.17     Notification   of   Advances,  Interest  Rates,   Prepayments  and
Commitment Reductions.  Promptly after receipt thereof, the Administrative Agent
will notify each Lender of the contents of each Aggregate  Commitment  reduction
notice,  Borrowing Notice, Swing Line Borrowing Notice,  Conversion/Continuation
Notice, and repayment notice received by it hereunder.  The Administrative Agent
will notify each  Lender of the  interest  rate  applicable  to each  Eurodollar
Advance  promptly  upon  determination  of such interest rate and will give each
Lender prompt notice of each change in the Alternate Base Rate.

     2.18     Lending  Installations.  Each  Lender  may  book its  Loans at any
Lending  Installation  selected  by such  Lender  and  may  change  its  Lending
Installation  from time to time. All terms of this Agreement  shall apply to any
such Lending  Installation and the Loans and any Notes issued hereunder shall be
deemed  held by each Lender for the  benefit of any such  Lending  Installation.
Each Lender may, by written notice to the Administrative  Agent and the Borrower
in accordance  with Article XIII,  designate  replacement or additional  Lending
Installations  through which Loans will be made by it and for whose account Loan
payments are to be made.

     2.19    Non-Receipt of  Funds  by  the  Administrative  Agent.  Unless  the
Borrower or Lender, as the case may be, notifies the Administrative  Agent prior
to the date on which it is scheduled to make payment to the Administrative Agent
of (i) in the  case of a  Lender,  the  proceeds  of a Loan or (ii) in the  case
of the Borrower, a payment of principal,  interest or fees to the Administrative
Agent for  the  account of  the  Lenders,  that it does not  intend to make such
payment, the Administrative Agent may assume that such  payment  has been  made.
The Administrative Agent may, but shall  not be obligated to, make the amount of
such  payment  available  to  the  intended  recipient  in  reliance  upon  such
assumption. If  such  Lender  or the  Borrower,  as the case may be,  has not in
fact  made  such  payment to the  Administrative  Agent,  the  recipient of such
payment   shall,  on   demand  by  the   Administrative  Agent,   repay  to  the
Administrative  Agent  the  amount  so  made  available  together  with interest
thereon in respect of each  day during the  period  commencing  on the date such
amount was so made  available  by  the Administrative  Agent  until the date the
Administrative  Agent  recovers  such amount at a rate per annum equal to (x) in
the case of payment by a Lender,  the Federal  Funds  Effective  Rate  for  such
day for the  first  three  days and, thereafter, the interest rate applicable to
the  relevant Loan or (y) in  the case of payment by  the Borrower, the interest
rate applicable to the relevant Loan.

     2.20     Replacement  of Lender.  If  the Borrower is required  pursuant to
Section 3.1, 3.2 or 3.5 to make any  additional  payment to any Lender or if any
Lender's obligation to make or continue, or to convert Advances into, Eurodollar
Advances  shall be suspended  pursuant to Section 3.3 (any Lender so affected an
"Affected  Lender"),  the  Borrower may elect,  if such  amounts  continue to be
charged or such suspension is still  effective,  to replace such Affected Lender
as a Lender  party to this  Agreement,  provided  that no Default  or  Unmatured
Default shall have  occurred and be continuing at the time of such  replacement,
and provided,  further,  that,

                                      -23-

concurrently  with such  replacement,  (i) another bank or other entity which is
reasonably  satisfactory  to the  Borrower  and the  Administrative  Agent shall
agree, as of such date, to purchase for cash the Advances and other  Obligations
due to the Affected Lender pursuant to an assignment  substantially  in the form
of Exhibit C and to become a Lender for all purposes under this Agreement and to
assume all  obligations of the Affected  Lender to be terminated as of such date
and to comply with the  requirements  of Section 12.3 applicable to assignments,
and (ii) the Borrower shall pay to such Affected Lender in same day funds on the
day of such  replacement  (A) all interest,  fees and other amounts then accrued
but unpaid to such  Affected  Lender by the Borrower  hereunder to and including
the date of  termination,  including  without  limitation  payments  due to such
Affected  Lender under  Sections  3.1,  3.2 and 3.5, and (B) an amount,  if any,
equal to the payment which would have been due to such Lender on the day of such
replacement under Section 3.4 had the Loans of such Affected Lender been prepaid
on such date rather than sold to the replacement Lender.


                                   ARTICLE III

                             YIELD PROTECTION; TAXES

     3.1      Yield Protection.  (a) If, on or after the date of this Agreement,
(x)  the  adoption  of  or  any  change  in  any  law  or  any  governmental  or
quasi-governmental rule, regulation,  policy, guideline or directive (whether or
not  having  the  force of law),  or (y) any  change  in the  interpretation  or
administration  thereof by any  governmental  or  quasi-governmental  authority,
central  bank  or  comparable   agency  charged  with  the   interpretation   or
administration  thereof,  or (z) compliance by any Lender or applicable  Lending
Installation  with any request or directive  (whether or not having the force of
law) issued on or after the date hereof of any such  authority,  central bank or
comparable agency:

              (i)      subjects   any   Lender   or   any   applicable   Lending
                       Installation  to  any  Taxes,  or  changes  the  basis of
                       taxation of payments (other than with respect to Excluded
                       Taxes) to any  Lender in respect of its Eurodollar Loans,
                       or

              (ii)     imposes  or increases or  deems applicable  any  reserve,
                       assessment, insurance charge,  special deposit or similar
                       requirement against  assets  of, deposits with or for the
                       account  of,  or credit  extended  by,  any  reserves and
                       assessments  taken   into  account  in   determining  the
                       interest rate applicable to Eurodollar Advances), or

              (iii)    imposes  any  other condition the result  of  which is to
                       increase the cost to any Lender or any applicable Lending
                       Installation   of  making,  funding  or maintaining   its
                       Eurodollar  Loans or reduces any amount receivable by any
                       Lender  or  any   applicable  Lending   Installation   i
                       connection  with its  Eurodollar  Loans, or requires  any
                       Lender or any applicable Lending Installation to make any
                       payment

                                     -24-

                       calculated by reference to the amount of Eurodollar Loans
                       held  or  interest received  by  it,  by an amount deemed
                       material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation of making or maintaining its Eurodollar Loans or
Commitment or to reduce the return received by such Lender or applicable Lending
Installation  in connection  with such  Eurodollar  Loans or  Commitment,  then,
within 15 days of demand by such Lender, the Borrower shall pay such Lender such
additional  amount or amounts as will  compensate such Lender for such increased
cost or reduction in amount  received.  A Lender shall not be entitled to demand
compensation  or be compensated  hereunder to the extent that such  compensation
relates  to any  period of time more than 60 days  prior to the date upon  which
such Lender first notified the Borrower of the occurrence of the event entitling
such  Lender to such  compensation  (unless,  and to the  extent,  that any such
compensation  so demanded  shall relate to the  retroactive  application  of any
event so notified to the Borrower).

     (b)      Without limiting  subsection (a) above, any Lender may require the
Borrower  to  pay,  contemporaneously  with  each  payment  of  interest  on any
Eurodollar Loan of such Lender, additional interest on such Eurodollar Loan at a
rate per annum  determined  by such Lender up to but not exceeding the excess of
(i) (A) the applicable Eurodollar Base Rate divided by (B) one minus the Reserve
Requirement over (ii) the applicable Eurodollar Base Rate. Any Lender wishing to
require payment of such additional interest (x) shall so notify the Borrower and
the  Administrative  Agent,  in  which  case  such  additional  interest  on the
Eurodollar  Loans of such  Lender  shall be payable to such  Lender at the place
indicated  in such notice with respect to each  Interest  Period  commencing  at
least three  Business  Days after the giving of such notice and (y) shall notify
the Borrower at least five Business Days prior to each date on which interest is
payable on any Eurodollar Loan of the amount then due it under this Section 3.1.

     3.2      Changes in  Capital Adequacy Regulations.  If a  Lender determines
the amount of capital required or expected to be maintained by such Lender,  any
Lending  Installation of such Lender or any corporation  controlling such Lender
is  increased  as a result of a Change,  then,  within 15 days of demand by such
Lender,  the Borrower  shall pay such Lender the amount  necessary to compensate
for any shortfall in the rate of return on the portion of such increased capital
which such Lender determines is attributable to this Agreement, its Loans or its
Commitment  to make Loans  hereunder  (after  taking into account such  Lender's
policies as to capital  adequacy).  "Change" means (i) any change after the date
of this Agreement in the Risk-Based  Capital  Guidelines or (ii) any adoption of
or change in any other law, governmental or quasi-governmental rule, regulation,
policy, guideline, interpretation, or directive (whether or not having the force
of law) after the date of this  Agreement  which  affects  the amount of capital
required or expected to be maintained by any Lender or any Lending  Installation
or any corporation controlling any Lender. "Risk-Based Capital Guidelines" means
(i) the risk-based capital guidelines in effect in the United States on the date
of this  Agreement,  including  transition  rules,  and (ii)  the  corresponding
capital  regulations  promulgated by regulatory  authorities  outside the United
States  implementing  the July 1988  report of the Basle  Committee  on  Banking
Regulation and  Supervisory  Practices  Entitled  "International  Convergence of
Capital

                                      -25-
<page>
Measurements  and  Capital  Standards,"  including  transition  rules,  and  any
amendments to such regulations adopted prior to the date of this Agreement.

     3.3      Availability  of Types  of Advances.   If  any  Lender  reasonably
determines  that  maintenance  of its  Eurodollar  Loans at a  suitable  Lending
Installation would violate any applicable law, rule,  regulation,  or directive,
whether or not having the force of law, or if the  Required  Lenders  reasonably
determine  that (i)  deposits of a type and maturity  appropriate  to match fund
Eurodollar  Advances are not available or (ii) the Eurodollar Base Rate does not
accurately  reflect the cost of obtaining  funds to make or maintain  Eurodollar
Advances,  then the  Administrative  Agent  shall  suspend the  availability  of
Eurodollar Advances and require any affected Eurodollar Advances to be repaid or
converted to Floating Rate Advances (on or before the date required by such law,
rule,  regulation  or  directive),   subject  to  the  payment  of  any  funding
indemnification amounts required by Section 3.4.

     3.4      Funding  Indemnification.  If any  payment of a Eurodollar Advance
occurs on a date which is not the last day of the  applicable  Interest  Period,
whether  because of  acceleration,  prepayment  or  otherwise,  or a  Eurodollar
Advance is not made,  continued or converted on a date specified by the Borrower
for any reason other than default by the Lenders,  the Borrower  will  indemnify
each Lender for any loss or cost incurred by it resulting therefrom,  including,
without  limitation,  any  loss or cost in  liquidating  or  employing  deposits
acquired to fund or maintain such Eurodollar Rate Advance.

     3.5      Taxes.  (i) All  payments by the Borrower to or for the account of
any Lender or the Administrative Agent hereunder or under any Note shall be made
free and clear of and without  deduction for any and all Taxes.  If the Borrower
shall be  required  by law to deduct  any Taxes  from or in  respect  of any sum
payable hereunder to any Lender or the Administrative Agent, (a) 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
3.5) such Lender or the  Administrative  Agent (as the case may be)  receives an
amount equal to the sum it would have received had no such deductions been made,
(b) the Borrower shall make such deductions, (c) the Borrower shall pay the full
amount deducted to the relevant  authority in accordance with applicable law and
(d) the Borrower shall furnish to the Administrative  Agent the original copy of
a receipt evidencing payment thereof within 30 days after such payment is made.

     (ii)     In addition, the  Borrower  hereby  agrees to  pay any  present or
future  stamp or  documentary  taxes  and any  other  excise or property  taxes,
charges or similar  levies which arise from any payment made  hereunder or under
any Note or from the  execution or  delivery of, or  otherwise  with respect to,
this Agreement or any Note ("Other Taxes").

     (iii)    The Borrower hereby agrees to  indemnify the Administrative  Agent
and each Lender for the full amount of Taxes or Other Taxes (including,  without
limitation,  any Taxes or Other  Taxes  imposed  on amounts  payable  under this
Section 3.5) paid by the  Administrative  Agent or such Lender and any liability
(including penalties, interest and expenses) arising therefrom or

                                      -26-

with  respect  thereto.  Payments due under this  indemnification  shall be made
within 30 days of the date the Administrative  Agent or such Lender makes demand
therefor pursuant to Section 3.6.

     (iv)     Each Lender that is not incorporated under the laws of the  United
States of America or a state thereof (each a "Non-U.S.  Lender")  agrees that it
will,  not less than ten  Business  Days after the date of this  Agreement,  (i)
deliver to each of the Borrower and the Administrative  Agent two duly completed
copies  of  United  States  Internal  Revenue  Service  Form W-8 BEN or W-8 ECI,
certifying in either case that such Lender is entitled to receive payments under
this  Agreement  without  deduction or  withholding of any United States federal
income  taxes,  and (ii) deliver to each of the Borrower and the  Administrative
Agent a United States Internal  Revenue Form W-8 or W-9, as the case may be, and
certify  that  it  is  entitled  to  an  exemption  from  United  States  backup
withholding tax. Each Non-U.S.  Lender further  undertakes to deliver to each of
the Borrower and the  Administrative  Agent (x) renewals or additional copies of
such form (or any  successor  form) on or before the date that such form expires
or becomes  obsolete,  and (y) after the  occurrence  of any event  requiring  a
change in the most recent  forms so delivered  by it, such  additional  forms or
amendments  thereto  as may be  reasonably  requested  by  the  Borrower  or the
Administrative  Agent.  All  forms  or  amendments  described  in the  preceding
sentence  shall certify that such Lender is entitled to receive  payments  under
this  Agreement  without  deduction or  withholding of any United States federal
income  taxes,  unless an event  (including  without  limitation  any  change in
treaty,  law or  regulation)  has  occurred  prior to the date on which any such
delivery would  otherwise be required which renders all such forms  inapplicable
or which would prevent such Lender from duly  completing and delivering any such
form or amendment  with  respect to it and such Lender  advises the Borrower and
the  Administrative  Agent that it is not capable of receiving  payments without
any deduction or withholding of United States federal income tax.

     (v)      For  any  period  during  which a Non-U.S. Lender  has  failed  to
provide the Borrower with an appropriate form pursuant to subsection (iv), above
(unless  such  failure is due to a change in treaty,  law or regulation,  or any
change in the  interpretation  or  administration  thereof  by  any governmental
authority,  occurring  subsequent  to the  date on  which a form  originally was
required  to  be  provided),  such  Non-U.S.  Lender  shall  not  be entitled to
indemnification  under  this  Section 3.5 with  respect to Taxes  imposed by the
United   States;  provided  that, should a  Non-U.S. Lender  which  is otherwise
exempt from or subject to a  reduced rate of  withholding  tax become subject to
Taxes because of its failure to deliver a form required  under  subsection (iv),
above, the  Borrower  shall  take  such  steps  as such  Non-U.S.  Lender  shall
reasonably  request to assist  such Non-U.S. Lender to recover such Taxes.

     (vi)     Any Lender that is  entitled  to an  exemption  from or  reduction
of withholding tax with respect  to payments  under this  Agreement  or any Note
pursuant to the law of any relevant  jurisdiction or any treaty shall deliver to
the Borrower  (with a copy to the  Administrative  Agent),  at the time or times
prescribed by applicable law, such properly completed and executed documentation
prescribed  by  applicable  law as will permit such  payments to be made without
withholding or at a reduced rate.

                                      -27-

     (vii)    If the U.S.  Internal  Revenue  Service or any  other governmental
authority of the United States or any other country or any political subdivision
thereof asserts a claim that the Administrative  Agent did not properly withhold
tax  from  amounts  paid  to or for  the  account  of any  Lender  (because  the
appropriate  form was not delivered or properly  completed,  because such Lender
failed to notify the  Administrative  Agent of a change in  circumstances  which
rendered its exemption from withholding  ineffective,  or for any other reason),
such Lender shall indemnify the Administrative Agent fully for all amounts paid,
directly  or  indirectly,  by  the  Administrative  Agent  as  tax,  withholding
therefor,  or otherwise,  including penalties and interest,  and including taxes
imposed by any jurisdiction on amounts payable to the Administrative Agent under
this subsection, together with all costs and expenses related thereto (including
attorneys fees and time charges of attorneys for the Administrative Agent, which
attorneys may be employees of the Administrative  Agent). The obligations of the
Lenders under this Section 3.5(vii) shall survive the payment of the Obligations
and termination of this Agreement.

     3.6      Lender  Statements;    Survival  of   Indemnity.   To  the  extent
reasonably  possible,  each   Lender  shall   designate  an  alternate   Lendin
Installation  with  respect to its Eurodollar  Loans to  reduce any liability of
the Borrower to such Lender  under Sections  3.1,  3.2 and 3.5 or to  avoid  the
unavailability  of  Eurodollar  Advances  under  Section 3.3,  so  long as  such
designation is not, in the reasonable  judgment of such Lender,  disadvantageous
to such Lender.  Each Lender shall deliver a written statement of such Lender to
the Borrower (with a copy to the  Administrative Agent) as to the amount due, if
any,  under Section  3.1,  3.2, 3.4 or 3.5.  Such  written  statement  shall set
forth in  reasonable detail the calculations  upon  which such Lender determined
such amount and shall be rebuttable  presumptive evidence of the amount thereof.
Determination  of  amounts  payable  under such  Sections in  connection  with a
Eurodollar Loan shall be calculated as though each Lender funded its  Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the  deposit  used  as a  reference  in  determining  the  Eurodollar  Base Rate
applicable to such Eurodollar Loan, whether in fact that is the case or not. The
obligations of the Borrower under Sections  3.1,  3.2, 3.4 and 3.5 shall survive
payment of the Obligations and termination of this Agreement.

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Lenders that:

     5.1      Organization.  The  Borrower and each of its Subsidiaries are duly
organized, validly existing and in good standing under the laws of the states of
their organization and have all requisite  authority to conduct their respective
businesses  in each  jurisdiction  in which the failure to have such  authority,
singly or in the  aggregate,  could  reasonably  be  expected to have a Material
Adverse Effect.  The Borrower and each of its  Subsidiaries  have full power and
authority to carry on their business as now conducted.

     5.2      Authorization and  Validity.  The Borrower and each  Guarantor has
the  power  and  authority and  egal  right to  execute  and  deliver  the  Loan
Documents to which it is a  party and to perform its obligations thereunder. The
execution and delivery by the Borrower and  each Guarantor of the Loan Documents
to which  it  is a  party  have  been  duly  authorized by proper organizational
proceedings,  and the Loan  Documents to which  the Borrower and such  Guarantor
is a party  constitute legal, valid  and binding  obligations of the Borrower or
such Guarantor,  as the case may be, enforceable  against  the  Borrower or such
Guarantor,  as  the case  may  be, in  accordance  with  their terms,  except as
enforceability  may  be  limited  by  bankruptcy,  insolvency  or  similar  laws
affecting the  enforcement of creditors' rights generally.

                                      -30-

     5.3      Financial  Statements.  The  December 31, 2000  and  the March 31,
2001 consolidated financial statements  of the  Borrower  and  the  Subsidiaries
heretofore  delivered to the Administrative  Agent and the Lenders were prepared
in accordance  with generally  accepted  accounting  principles in effect on the
date such statements were prepared and fairly present the financial position and
results of operations of the Borrower and its Subsidiaries at such dates and the
consolidated results of their operations for the periods then ended.

     5.4      Subsidiaries.  Schedule  5.4 hereto  contains  an accurate list of
all of  the presently existing  Subsidiaries,  setting  forth  their  respective
jurisdictions  of organization  and the percentage of their  respective  capital
stock or membership  interests owned by the Borrower or other Subsidiaries.  All
of the  issued  and  outstanding  shares  of  capital  stock  of each  corporate
Subsidiary  have  been  duly  authorized  and  issued  and are  fully  paid  and
nonassessable.

     5.5      ERISA.  Each  Plan is in material compliance  with,  an  has  been
administered in material  compliance  with, all applicable  provisions of ERISA,
the Code and any other applicable federal or state law, except where the failure
to so comply would not (individually or in the aggregate) reasonably be expected
to have a Material Adverse Effect, and no event or condition has occurred and is
continuing  as to which the Borrower is under an  obligation to furnish a report
to the Administrative Agent and the Lenders under Section 6.1(d) and which would
reasonably  be expected  (individually  or in the  aggregate) to have a Material
Adverse Effect.

     5.6      Defaults.  No  Default or  Unmatured  Default  has occurred and is
continuing.

     5.7      Accuracy  of  Information.   No information,  exhibit  or   report
furnished by the Borrower or any Subsidiary to the  Administrative  Agent or any
Lender in connection  with  the  negotiation  of  this  Agreement  contains  any
material misstatement  of fact or omitted to state a material fact  necessary to
make the statements contained therein not misleading.

     5.8      Regulation  U. Neither the Borrower nor any Subsidiary  is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of  purchasing  or carrying  Margin  Stock.  Margin Stock
constitutes  less than 25% of the  consolidated  assets of the  Borrower and its
Subsidiaries  which are subject to any limitation on sale or pledge or any other
restriction  hereunder.  No part of the  proceeds  of any  Loan  will be used to
purchase or carry any Margin Stock in violation of Regulation U.

     5.9      No Adverse Change.  Since March 31, 2001 there  has been no change
in the business, property, condition  (financial  or  otherwise)  or  results of
operations  of the  Borrower  and its  Subsidiaries  which could  reasonably  be
expected to have a Material Adverse Effect.

     5.10     Taxes.  The  Borrower  and its  Subsidiaries have filed all United
States federal tax returns and all other tax returns which,  to the Knowledge of
the  Borrower,  are required to be filed and have paid all taxes due pursuant to
said returns or material  taxes due pursuant to any  assessment  received by the
Borrower  or any  Subsidiary,  except in both cases such  taxes,  if any, as are
being  contested  in good  faith  and as to which  adequate  reserves  have been
provided in

                                      -31-

accordance  with  Agreement  Accounting  Principles.  The charges,  accruals and
reserves on the books of the  Borrower  and its  Subsidiaries  in respect of any
taxes or other  governmental  charges are adequate in accordance  with Agreement
Accounting Principles.

     5.11     Liens.  There are no Liens on any of the  properties  or assets of
the Borrower or any Subsidiary  except (i) Liens  permitted by Section 6.3.5 and
(ii) with  respect to properties and assets other  than  Productive  Properties,
Principal  Transmission  Facilities and the stock of any Subsidiary,  Liens that
could not,  individually  or in the aggregate,  reasonably be expected to have a
Material Adverse Effect.  All easements,  rights of way, licenses and other real
property rights required for operation of the businesses of the Borrower and its
Subsidiaries  (collectively the "Rights of Way") are owned free and clear of any
Lien,  other than Liens  permitted by this  Agreement  and Liens  already on any
parcel  of real  property  with  respect  to which  the  Rights of Way have been
granted,  which will not, in the aggregate,  at any time materially detract from
the value of the Rights of Way or materially impair the use of the Rights of Way
in the operation of the businesses of the Borrower and its Subsidiaries.

     5.12     Compliance with Orders. Neither the Borrower nor any Subsidiary is
in  default  under  the  terms of any  order of any  federal  or state  court or
administrative  agency by which it or any of its properties may be bound, except
for  any  defaults  which  could  not,  individually  or in  the  aggregate,  be
reasonably expected to have a Material Adverse Effect.

     5.13     Litigation.  Except as set forth in  Schedule  5.13,  there are no
actions  at law or in equity  pending  or,  to the  Knowledge  of the  Borrower,
threatened  involving the  likelihood  of any judgment or liability  against the
Borrower or any Subsidiary which could reasonably be expected to have a Material
Adverse Effect.

     5.14     Burdensome Agreements. The Borrower is not a party to any contract
or  agreement  which,  in the  opinion  of  management  of the  Borrower,  could
reasonably be expected to have a Material Adverse Effect.

     5.15     No Conflict. Neither the execution and delivery by the Borrower or
any Guarantor of the Loan Documents to which it is a party, nor the consummation
of the  transactions  therein  contemplated,  nor compliance with the provisions
thereof  will  conflict  with  or  result  in the  breach  of any of the  terms,
conditions  or  provisions  of, or  constitute a default  under,  the charter or
bylaws of the Borrower or any  Subsidiary,  or any indenture,  loan agreement or
other agreement or instrument to which the Borrower or any Subsidiary is a party
or by which it may be bound,  or result in creation of any Lien on any  property
of the Borrower or any  Subsidiary,  and neither the Borrower nor any Subsidiary
is in default  (after the  expiration  of any  applicable  grace  period) in the
performance,  observance or fulfillment of any of the obligations,  covenants or
conditions  contained in (i) any agreement to which it is a party, which default
could  reasonably  be expected to have a Material  Adverse  Effect,  or (ii) any
agreement or  instrument  evidencing  or governing  Indebtedness  in a principal
amount exceeding $5,000,000.

                                      -32-

     5.16     Title to Properties.  The Borrower and its  Subsidiaries have good
and marketable  title to all real  properties  purported to be owned by them and
good title to all other assets  purported  to be owned by them,  subject to such
minor  defects as are common to property of the type owned by the  Borrower  and
its  Subsidiaries  and Liens  permitted by this  Agreement  and such defects and
Liens in the aggregate do not materially interfere with or impair the Borrower's
or any Subsidiary's business as presently conducted.

     5.17     Public  Utility   Holding   Company  Act.  The  Borrower  and  the
Subsidiaries  are exempt from  registration  under the  provisions of the Public
Utility Holding Company Act of 1935 pursuant to Section 3(a) thereof.

     5.18     Regulatory Approval.  No consent or authorization of, filing with,
or any other act by or in respect of any Person is required in  connection  with
the  enforceability,  execution,  delivery,  performance  or  validity  of  this
Agreement or the transactions contemplated thereby.

     5.19     Negative Pledge.   Except as set forth in  Schedule  5.19  hereto,
neither the Borrower nor any Subsidiary is subject to any agreement,  indenture,
instrument,  undertaking or security (other than this Agreement) which prohibits
the creation, incurrence or sufferance to exist of any Lien.

     5.20     Investment  Company  Act.  The  Borrower  is  not  an  "investment
company"  or  a  Borrower "controlled"  by  an "investment company",  within the
meaning of the Investment Company Act of 1940, as amended.

     5.21     Compliance with Laws.  The Borrower and its  Subsidiaries have all
franchises,  licenses and permits  necessary for the conduct of their respective
businesses,  and are in compliance with all laws,  rules,  regulations,  orders,
writs,  judgments,  injunctions,  decrees or awards to which it may be  subject,
including,  without limitation, (i) all provisions of ERISA, which, if violated,
might  result in a Lien or  charge  upon any  property  of the  Borrower  or any
Subsidiary,  and (ii) all material  provisions  of the  Occupational  Safety and
Health  Act of 1970 and the  rules and  regulations  thereunder  and  applicable
statutes,   regulations,  orders  and  restrictions  relating  to  environmental
standards or  controls,  except to the extent that failure to maintain or comply
with any of the foregoing,  singly and in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.


                                   ARTICLE VI

reasonable  times  and   intervals  during   regular   business   hours  as  the

or sale of assets as  permitted by Section  6.3.2) and  maintain  all  requisite

of all  or any  part  of  the  property  and  business  of the  Borrower  or any
Subsidiary,  and all due and payable claims for work, labor or materials,  which
if  unpaid  might  become  a Lien  upon  any  property  of the  Borrower  or any

leasehold  interest) in good repair,  working order and condition,  and make all

business  carried on in connection  therewith  may be properly  conducted at all
times;  provided  that,  subject  to Section  6.3.2 and all other  terms of this
Agreement,  nothing in this Section  6.2.6 shall  prevent the Borrower or any of

transaction,  the  aggregate  fair market  value of all assets  sold,  leased or
otherwise disposed of by the Borrower and its Subsidiaries in any fiscal year of
the Borrower (minus all Net Cash Proceeds thereof applied t reduce the Aggregate

                             RELEASES OF GUARANTORS

     8.1      Acceleration.  If any Default described in  Section 7.1.6 or 7.1.7
occurs with  respect to the  Borrower,  the  obligations  of the Lenders to make
Loans  hereunder  shall  automatically   terminate  and  the  Obligations  shall
immediately become due and payable without any election or action on the part of
the  Administrative  Agent or any  Lender.  If any  other  Default  occurs,  the
Required Lenders (or the  Administrative  Agent with the consent of the Required
Lenders) may terminate or suspend the  obligations  of the Lenders to make Loans
hereunder,  or declare the Obligations to be due and payable, or both, whereupon
the Obligations shall become immediately due and payable,  without  presentment,
demand,  protest  or  notice  of any  kind,  all of which  the  Borrower  hereby
expressly waives.

     If, within  30 days  after acceleration of  the maturity of the Obligations
or  termination of the  obligations of the Lenders to make Loans  hereunder as a
result of any Default  (other than any Default as described in Section  7.1.6 or
7.1.7 with  respect to the  Borrower)  and before any judgment or decree for the
payment of the Obligations due shall have been obtained or entered, the Required
Lenders (in their sole discretion)  shall so direct,  the  Administrative  Agent
shall,  by notice to the Borrower,  rescind and annul such  acceleration  and/or
termination.

     8.2      Amendments.  Subject  to  the provisions of this Article VIII, the
Required Lenders (or the Administrative Agent with the consent in writing of the
Required Lenders) and the Borrower may enter into agreements supplemental hereto
for the purpose of adding to or modifying  any provision in any Loan Document or
changing in any manner the rights of the Lenders or the  Borrower  hereunder  or
waiving any Default  hereunder;  provided  that no such  supplemental  agreement
shall, without the consent of all of the Lenders:

                      (i)     Extend  the final maturity  of any Loan or forgive
                              all  or  any  portion  of   the  principal  amount
                              thereof, or reduce the  rate or extend the time of
                              payment of interest or fees thereon.

                      (ii)    Reduce the percentage specified in  the definition
                              of Required Lenders.

                      (iii)   Extend the Termination  Date, or reduce the amount
                              or extend  the  payment  date for,  the  mandatory
                              payments  required under Section 2.12, or increase
                              the amount of the  Aggregate  Commitment or of the
                              Commitment of any Lender hereunder,  or permit the
                              Borrower   to  assign   its   rights   under  this
                              Agreement.

                      (iv)    Amend the last paragraph of Section  6.3.2 or this
                              Section 8.2.

                                      -46-

                      (v)     Release any Guarantor from its  obligations  under
                              the  Subsidiary  Guaranty  (except as  provided in
                              Section 8.4).

No amendment of any provision of this Agreement  relating to the  Administrative
Agent  shall be  effective  without the  written  consent of the  Administrative
Agent.  No amendment of any  provision of this  Agreement  relating to the Swing
Line  Lender or any Swing  Line Loan  shall be  effective  without  the  written
consent of the Swing Line Lender. The Administrative  Agent may waive payment of
the fee required under Section 12.3.2 without obtaining the consent of any other
party to this Agreement.

     8.3      Preservation  of Rights.  No  delay or omission of  the Lenders or
the  Administrative  Agent to exercise any right under the Loan Documents  shall
impair  such  right  or be  construed  to  be a  waiver  of  any  Default  or an
acquiescence  therein, and the making of a Loan notwithstanding the existence of
a Default or the inability of the Borrower to satisfy the  conditions  precedent
to such Loan  shall not  constitute  any waiver or  acquiescence.  Any single or
partial  exercise of any such right shall not preclude other or further exercise
thereof or the  exercise of any other right,  and no waiver,  amendment or other
variation  of  the  terms,  conditions  or  provisions  of  the  Loan  Documents
whatsoever  shall be valid  unless in  writing  signed by the  Lenders  required
pursuant  to  Section  8.2,  and  then  only  to  the  extent  in  such  writing
specifically set forth.  All remedies  contained in the Loan Documents or by law
afforded  shall be cumulative  and all shall be available to the  Administrative
Agent and the Lenders until the Obligations have been paid in full.

     8.4      Releases  of  Guarantors.   The  Lenders  hereby   authorize   the
Administrative  Agent to,  and the  Administrative  Agent  agrees  that it will,
release any Guarantor from its obligations under the Subsidiary Guaranty so long
as (a) no Default or Unmatured  Default exists or will result  therefrom and (b)
either (i) such Guarantor ceases to be a Subsidiary as a result of a transaction
permitted  hereunder or (ii) the Borrower  requests such release in writing and,
after giving effect  thereto,  the Borrower  will be in compliance  with Section
6.3.4. In determining whether any such release is permitted,  the Administrative
Agent may rely on a certificate  from the  Borrower.  The  Administrative  Agent
shall promptly notify the Lenders of any such release.


                                   ARTICLE IX

                               GENERAL PROVISIONS

the Borrower  contained in this Agreement  shall survive the making of the Loans
herein contemplated.

     9.2      Governmental  Regulation.  Anything contained in this Agreement to
the contrary  notwithstanding,  no Lender shall be obligated to extend credit to
the Borrower in  violation  of any  limitation  or  prohibition  provided by any
applicable statute or regulation.

the provisions of the Loan Documents.

and understanding among the Borrower,  the Administrative  Agent and the Lenders
and supersede all prior agreements and  understandings  among the Borrower,  the
Administrative Agent and the Lenders relating to the subject matter thereof.

     9.5      Several  Obligations; Benefits of this  Agreement.  The respective
obligations  of the  Lenders  hereunder  are several and not joint and no Lender
shall be the  partner  or agent of any other  (except to the extent to which the
Administrative Agent is authorized to act as such). The failure of any Lender to
perform any of its obligations hereunder shall not relieve any other Lender from
any of its obligations hereunder. This Agreement shall not be construed so as to
confer any right or  benefit  upon any  Person  other  than the  parties to this
Agreement and their respective successors and assigns, provided that the parties
hereto  expressly  agree  that the  Arranger  shall  enjoy the  benefits  of the
provisions of Sections 9.6, 9.10 and 10.11 to the extent  specifically set forth
therein and shall have the right to enforce  such  provisions  on its own behalf
and in its own name to the same extent as if it were a party to this Agreement.

attorneys for the Administrative  Agent, which attorneys may be employees of the
Administrative  Agent)  paid or  incurred  by the  Administrative  Agent  or the
Arranger in connection with the preparation,  negotiation,  execution, delivery,
syndication,  review,  amendment,  modification,  and administration of the Loan
Documents.  The Borrower also agrees to reimburse the Administrative  Agent, the
Arranger  and the  Lenders  for  all  reasonable  costs,  internal  charges  and
out-of-pocket expenses (including reasonable attorneys' fees and reasonable time
charges of attorneys for the Administrative Agent, the Arranger and the Lenders,
which attorneys may be employees of the  Administrative  Agent,  the Arranger or
any Lender) paid or incurred by the  Administrative  Agent,  the Arranger or any
Lender in connection with the collection and enforcement of the Loan Documents.

     (ii)     The Borrower hereby further agrees to indemnify the Administrative
Agent, the Arranger, each Lender, their respective affiliates, and each of their
directors,   officers  and  employees  against  all  losses,  claims,   damages,
penalties,  judgments,  liabilities and reasonable expenses (including,  without
limitation,  all  reasonable  expenses of  litigation  or  preparation  therefor
whether  or not the  Administrative  Agent,  the  Arranger,  any  Lender  or any
affiliate is a party  thereto) which any of them may pay or incur arising out of
or  relating  to this  Agreement,  the other Loan  Documents,  the  transactions
contemplated   hereby  or  the  direct  or  indirect   application  or  proposed
application of the proceeds of any Loan hereunder except to the extent that they
are  determined  in a final  non-appealable  judgment  by a court  of  competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
the party seeking

                                      -48-

indemnification.  The obligations of the Borrower  under this  Section 9.6 shall
survive the termination of this Agreement.

and  requests  hereunder  shall be furnished  to the  Administrative  Agent with
sufficient counterparts so that the Administrative Agent may furnish one to each
of the Lenders.

     9.8      Accounting.  Except  as  provided  to  the contrary   herein,  all
accounting   terms  used  herein  shall  be   interpreted   and  all  accounting
determinations  hereunder shall be made in accordance with Agreement  Accounting
Principles.

     9.9      Severability  of  Provisions.  Any  provision in any Loan Document
that  is held to be inoperative,  unenforceable, or invalid in  any jurisdiction
shall, as  to  that  jurisdiction,  be  inoperative,  unenforceable,  or invalid
without  affecting   the   remaining   provisions  in that  jurisdiction  or the
operation,  enforceability,  or  validity  of  that  provision  in   any   other
jurisdiction, and to this end the provisions of all  Loan Documents are declared
to be severable.

     9.10     Nonliability of Lenders.  The relationship between the Borrower on
the one hand and the  Lenders  and the  Administrative  Agent on the other  hand
shall be solely that of borrower and lender.  None of the Administrative  Agent,
the  Arranger or any Lender  shall have any  fiduciary  responsibilities  to the
Borrower.  None  of  the  Administrative  Agent,  the  Arranger  or  any  Lender
undertakes any  responsibility  to the Borrower to review or inform the Borrower
of any  matter  in  connection  with any  phase of the  Borrower's  business  or
operations.  The  Borrower  agrees that none of the  Administrative  Agent,  the
Arranger or any Lender shall have liability to the Borrower (whether sounding in
tort,  contract or otherwise) for losses  suffered by the Borrower in connection
with,  arising out of, or in any way related to, the  transactions  contemplated
and the relationship  established by the Loan Documents, or any act, omission or
event  occurring in  connection  therewith,  unless it is  determined in a final
non-appealable  judgment by a court of competent  jurisdiction  that such losses
resulted from the gross negligence or willful misconduct of the party from which
recovery is sought. None of the Administrative Agent, the Arranger or any Lender
shall have any  liability  with  respect  to, and the  Borrower  hereby  waives,
releases  and agrees not to sue for,  any  special,  indirect  or  consequential
damages suffered by the Borrower in connection  with,  arising out of, or in any
way related to the Loan Documents or the transactions contemplated thereby.

     9.11     Confidentiality.  Each  Lender agrees  to  hold  any  confidential
information which it may receive from the Borrower pursuant to this Agreement in
confidence,  except  for  disclosure  (i)  to  the  extent  permitted  by law or
regulation,  to its  Affiliates  and  to  other  Lenders  and  their  respective
Affiliates, (ii) to legal counsel,  accountants, and other professional advisors
to such Lender or to a Transferee,  (iii) to regulatory  officials,  (iv) to any
Person as required by law,  regulation,  or legal process,  (v) to any Person in
connection  with any legal  proceeding  to which  such  Lender is a party to the
extent required by law,  regulation or legal process,  (vi) permitted by Section
12.4, (vii) to rating agencies if required by such agencies in connection with a
rating relating to the Advances hereunder,  and (viii) to the extent required in
connection with the

                                      -49-

exercise of any remedy or any  enforcement of this  Agreement by  such Lender or
the Administrative Agent.

     9.12     Nonreliance.  Each Lender hereby represents that it is not relying
on or looking to any margin  stock (as defined in  Regulation  U of the Board of
Governors of the Federal Reserve System) for the repayment of the Loans provided
for herein.

     9.13     Disclosure.  The Borrower and  each Lender hereby (i)  acknowledge
and  agree  that  Bank One  and/or  its  Affiliates  from  time to time may hold
investments  in,  make  other  loans  to or have  other  relationships  with the
Borrower and its  Affiliates,  and (ii) waive any  liability of Bank One or such
Affiliate of Bank One to the Borrower or any Lender,  respectively,  arising out
of or  resulting  from  such  investments,  loans or  relationships  other  than
liabilities  arising out of the gross  negligence or willful  misconduct of Bank
One or its Affiliates.


                                    ARTICLE X

                            THE ADMINISTRATIVE AGENT

     10.1     Appointment; Nature of Relationship.  Bank One is hereby appointed
by each of the  Lenders as  the  Administrative  Agent hereunder  and under each
other  Loan  Document,  and  each  of  the  Lenders irrevocably  authorizes  the
Administrative Agent to act as the  contractual  representative  of  such Lender
with the rights and duties  expressly  set forth  herein  and in the other  Loan
Documents.  The  Administrative  Agent  agrees to  act as  Administrative  Agent
upon the  express conditions  contained in  this Article X.  Notwithstanding the
use of  the defined term  "Administrative  Agent," it  is  expressly  understood
and  agreed  that  the   Administrative  Agent  shall  not  have  any  fiduciary
responsibilities  to  any  Lender by reason of this  Agreement or any other Loan
Document  and  that  Administrative  Agent is merely  acting as the  contractual
representative  of  the  Lenders  with  only those duties as are  expressly  set
forth in this  Agreement  and the other Loan  Documents.   In  its  capacity  as
the  Administrative   Agent,  (i)  the Administrative  Agent does not assume any
fiduciary  duties  to  any  of  the Lenders, (ii) the Administrative  Agent is a
"representative"  of the Lenders within the meaning  of  Section  9-105  of  the
Uniform  Commercial  Code  and  (iii)  the Administrative  Agent is acting as an
independent  contractor,  the  rights and duties of  which are  limited to those
expressly  set forth in  this  Agreement and the other Loan  Documents.  Each of
the Lenders hereby agrees to assert no claim  against the  Administrative  Agent
on any agency  theory or any other  theory of  liability for breach of fiduciary
duty,  all of which claims each Lender hereby waives.

     10.2     Powers.  The Administrative Agent shall have and may exercise such
powers  under  the  Loan  Documents  as  are   specifically   delegated  to  the
Administrative Agent by the terms of each thereof,  together with such powers as
are reasonably  incidental thereto.  The Administrative Agent shall not have any
implied  duties to the  Lenders,  or any  obligation  to the Lenders to take any
action thereunder except any action specifically  provided by the Loan Documents
to be taken by the Administrative Agent.

                                      -50-

     10.3     General Immunity.  Neither the Administrative Agent nor any of the
Administrative Agent's directors,  officers, agents or employees shall be liable
to the Borrower, the Lenders or any Lender for any action taken or omitted to be
taken by it or them  hereunder or under any other Loan Document or in connection
herewith or therewith except to the extent such action or inaction is determined
in a final non-appealable  judgment by a court of competent jurisdiction to have
arisen from the gross negligence or willful misconduct of such Person.

    10.4      No   Responsibility   for  Loans,  Recitals,  etc.    Neither  the
Administrative Agent nor any of the Administrative Agent's directors,  officers,
agents or  employees  shall be  responsible  for or have any duty to  ascertain,
inquire into, or verify (a) any statement,  warranty or  representation  made in
connection  with  any  Loan  Document  or  any  borrowing  hereunder;   (b)  the
performance  or  observance of any of the covenants or agreements of any obligor
under any Loan  Document,  including,  without  limitation,  any agreement by an
obligor to furnish information  directly to each Lender; (c) the satisfaction of
any condition  specified in Article IV, except for the receipt of items required
to be delivered  solely to  Administrative  Agent; (d) the existence or possible
existence of any Default or Unmatured Default; (e) the validity, enforceability,
effectiveness,  sufficiency  or  genuineness  of any Loan  Document or any other
instrument or writing  furnished in connection  therewith;  or (f) the financial
condition  of  the  Borrower  or of  any of  the  Borrower's  Subsidiaries.  The
Administrative  Agent  shall  not  have  any  duty to  disclose  to the  Lenders
information  that  is  not  required  to be  furnished  by the  Borrower  to the
Administrative Agent at such time, but is voluntarily  furnished by the Borrower
to the Administrative  Agent (either in its capacity as the Administrative Agent
or in its individual capacity).

    10.5      Action on Instructions of Lenders.  The Administrative Agent shall
in  all  cases  be  fully  protected  in  acting, or in  refraining from acting,
hereunder  and  under  any  other  Loan  Document  in  accordance  with  written
instructions  signed  by  the  Required  Lenders (or,  when  expressly  required
hereunder,  all of the Lenders),  and such  instructions and any action taken or
failure  to  act  pursuant  thereto  shall  be  binding  on  all of the Lenders.
The  Lenders hereby  acknowledge that  the  Administrative  Agent  shall  not be
under  any  duty  to  take  any discretionary  action  permitted  to be taken by
it  pursuant to  the provisions of this  Agreement  or any other  Loan  Document
unless  it  shall  be  requested  in  writing to do so by the Required  Lenders.
Each  Administrative  Agent shall be fully  justified in  failing or refusing to
take any  action  hereunder  and  under any  other Loan Document unless it shall
first be indemnified to its  satisfaction by the Lenders  (ratably in accordance
with  their  respective  Pro Rata  Shares) against any and all  liability,  cost
and expense that it may incur by reason of taking or continuing to take any such
action. The  Administrative  Agent agrees, upon the request of any Lender at any
time an Unmatured  Default exists, to give a written  notice to the  Borrower of
the type  described  in Section  7.1.3 or 7.1.4.

     10.6     Employment  of  Agents  and Counsel.  The Administrative Agent may
execute  any of its duties as Administrative Agent hereunder and under any other
Loan  Document by or  through employees, agents, and attorneys-in-fact and shall
not be  answerable to the Lenders, except as to  money or securities received by
it or its authorized agents, for the default or

                                      -51-

misconduct  of  any  such  agents  or  attorneys-in-fact  selected  by  it  with
reasonable care. The Administrative Agent shall be entitled to advice of counsel
concerning the contractual  arrangement between the Administrative Agent and the
Lenders  and  all  matters  pertaining  to  the  Administrative  Agent's  duties
hereunder and under any other Loan Document.

     10.7     Reliance on Documents; Counsel.  The Administrative Agent shall be
entitled to rely upon any Note, notice, consent, certificate, affidavit, letter,
telegram,  statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in respect
to legal  matters,  upon the opinion of counsel  selected by the  Administrative
Agent, which counsel may be employees of the Administrative Agent.

     10.8     Administrative  Agent's  Reimbursement  and  Indemnification.  The
Lenders agree to reimburse and indemnify the  Administrative  Agent,  ratably in
accordance  with their  respective  Pro Rata  Shares,  (i) for any  amounts  not
reimbursed  by the  Borrower for which the  Administrative  Agent is entitled to
reimbursement  by the  Borrower  under  the Loan  Documents,  (ii) for any other
expenses  incurred  by the  Administrative  Agent on behalf of the  Lenders,  in
connection  with  the  preparation,   execution,  delivery,  administration  and
enforcement  of the  Loan  Documents  (including,  without  limitation,  for any
expenses  incurred by the  Administrative  Agent in connection  with any dispute
between  the  Administrative  Agent and any Lender or between two or more of the
Lenders) and (iii) for any liabilities, obligations, losses, damages, penalties,
actions,  judgments,  suits,  costs,  expenses or  disbursements of any kind and
nature  whatsoever  which may be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of the Loan Documents
or any other  document  delivered in  connection  therewith or the  transactions
contemplated  thereby  (including,  without  limitation,  for any  such  amounts
incurred by or asserted against the Administrative  Agent in connection with any
dispute between the  Administrative  Agent and any Lender or between two or more
of the Lenders), or the enforcement of any of the terms of the Loan Documents or
of any such other documents,  provided that (i) no Lender shall be liable to the
Administrative Agent for any of the foregoing to the extent any of the foregoing
is found in a final non-appealable judgment by a court of competent jurisdiction
to have  resulted  from  the  gross  negligence  or  willful  misconduct  of the
Administrative  Agent and (ii) any indemnification  required pursuant to Section
3.5(vii) shall,  notwithstanding the provisions of this Section 10.8, be paid by
the relevant Lender in accordance with the provisions  thereof.  The obligations
of the Lenders under this Section 10.8 shall survive  payment of the Obligations
and termination of this Agreement.

     10.9     Notice of Default.  The  Administrative  Agent  shall be deemed to
have knowledge or notice of the occurrence of any Default or  Unmatured  Default
hereunder  unless the  Administrative  Agent has received  written notice from a
Lender or the Borrower  referring to this Agreement  describing  such Default or
Unmatured Default and stating that such notice is a "notice of default".  In the
event that the  Administrative  Agent receives such a notice, the Administrative
Agent shall give prompt notice thereof to the Lenders.

     10.10    Rights as a Lender.  In the  event  the Administrative  Agent is a
Lender, the Administrative Agent shall have the same rights and powers hereunder
and under any other Loan

                                      -52-

Document  with  respect  to its  Commitment  and its Loans as any Lender and may
exercise the same as though it were not the  Administrative  Agent, and the term
"Lender" or  "Lenders"  shall,  at any time when the  Administrative  Agent is a
Lender, unless the context otherwise indicates, include the Administrative Agent
in its  individual  capacity.  The  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  Document,  with  the  Borrower  or  any  of its
Subsidiaries in which the Borrower or such  Subsidiary is not restricted  hereby
from engaging with any other Person. The Agent, in its individual  capacity,  is
not obligated to remain a Lender.

     10.11    Lender  Credit  Decision.  Each Lender  acknowledges  that it has,
independently and without reliance upon the  Administrative  Agent, the Arranger
or any  other  Lender  and based on the  financial  statements  prepared  by the
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 Documents.  Each Lender also acknowledges that it will, independently
and without  reliance upon the  Administrative  Agent, the Arranger or any other
Lender and based on such documents and information as it shall deem  appropriate
at the time,  continue to make its own credit  decisions in taking or not taking
action under this Agreement and the other Loan Documents.

     10.12    Successor  Administrative  Agent.  The  Administrative  Agent  may
resign  at any  time by  giving  written  notice  thereof to the Lenders and the
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 days after the retiring Administrative Agent gives notice
of its intention to resign. The Administrative  Agent may be removed at any time
with or without cause by written  notice  received by the  Administrative  Agent
from the Required Lenders, such removal to be effective on the date specified by
the Required  Lenders.  Upon any  resignation  or removal of the  Administrative
Agent, the Required Lenders shall have the right (with, so long as no Default or
Unmatured  Default  exists,  the  consent of the  Borrower,  which  shall not be
unreasonably  withheld) to appoint, on behalf of the Borrower and the Lenders, a
successor  Administrative Agent. If no successor Administrative Agent shall have
been so appointed by the Required Lenders within thirty days after the resigning
Administrative  Agent's  giving  notice of its  intention  to  resign,  then the
resigning  Administrative  Agent may appoint,  on behalf of the Borrower and the
Lenders,  a  successor   Administrative  Agent.   Notwithstanding  the  previous
sentence,  the  Administrative  Agent may at any time without the consent of any
Lender and with the consent of the Borrower,  not to be unreasonably withheld or
delayed, appoint any of its Affiliates which is a commercial bank as a successor
Administrative Agent hereunder. If the Administrative Agent has resigned or been
removed and no successor  Administrative  Agent has been appointed,  the Lenders
may  perform  all the  duties  of the  Administrative  Agent  hereunder  and the
Borrower shall make all payments in respect of the Obligations to the applicable
Lender and for all other  purposes  shall deal  directly  with the  Lenders.  No
successor  Administrative  Agent shall be deemed to be appointed hereunder until
such  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

                                      -53-

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
the Administrative Agent, the resigning or removed Administrative Agent shall be
discharged  from  its  duties  and  obligations  hereunder  and  under  the Loan
Documents.  After  the  effectiveness  of  the  resignation  or  removal  of the
Administrative  Agent, the provisions of this Article X shall continue in effect
for the benefit of the such Person in respect of any actions taken or omitted to
be taken by such  Person  while such Person was acting as  Administrative  Agent
hereunder  and under the other  Loan  Documents.  In the event  that  there is a
successor to the  Administrative  Agent by merger, or the  Administrative  Agent
assigns its duties and  obligations  to an  Affiliate  pursuant to this  Section
10.12, 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.

     10.13    Delegation to Affiliates.  The Borrower and the Lenders agree that
the Administrative  Agent may delegate any of its duties under this Agreement to
any of its  respective  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  the
Administrative Agent is entitled under Articles IX and X.

     10.14    Other  Agents.  No  Lender  identified  on the  cover  page or the
signature  pages of this  Agreement or  otherwise  herein,  or in any  amendment
hereof or other document related hereto, as being the "Syndication  Agent" shall
have any right, power, obligation, liability,  responsibility or duty under this
Agreement in such  capacity  other than those  applicable  to all Lenders.  Each
Lender  acknowledges that it has not relied, and will not rely, on any Person so
identified  in deciding to enter into this  Agreement or in taking or refraining
from taking any action hereunder or pursuant hereto.



                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS


     11.1     Setoff.  In addition to, and without limitation  of, any rights of
the Lenders under  applicable law, if the Borrower  becomes  insolvent,  however
evidenced,  or any Default occurs,  any and all deposits  (including all account
balances,  whether  provisional  or  final  and  whether  or  not  collected  or
available) and any other Indebtedness at any time held or owing by any Lender or
any  Affiliate of any Lender to or for the credit or account of the Borrower may
be offset and  applied  toward  the  payment  of the  Obligations  owing to such
Lender, whether or not the Obligations, or any part thereof, shall then be due.

     11.2     Ratable  Payments.  If any Lender, whether by setoff or otherwise,
has payment made to it upon its Ratable Loans or its participation in Swing Line
Loans (other than payments

                                      -54-

received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater  proportion than
that received by any other Lender, such Lender agrees,  promptly upon demand, to
purchase a portion of the Loans (or  participations in Swing Line Loans) held by
the other Lenders so that after such purchase each Lender will hold its Pro Rata
Share of all Ratable  Loans (and  participations  in Swing Line  Loans).  If any
Lender,  whether in connection  with setoff or amounts which might be subject to
setoff or otherwise, receives collateral or other protection for its Obligations
or such amounts  which may be subject to setoff,  such Lender  agrees,  promptly
upon demand,  to take such action  necessary  such that all Lenders share in the
benefits of such collateral  ratably in proportion to their  respective Pro Rata
Shares.  In case any such payment is disturbed by legal  process,  or otherwise,
appropriate further adjustments shall be made.



                                   ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS


     12.1     Successors  and  Assigns.  The  terms and  provisions  of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders  and  their  respective  successors  and  assigns,  except  that (i) the
Borrower shall not have the right to assign its rights or obligations  under the
Loan  Documents and (ii) any assignment by any Lender must be made in compliance
with Section 12.3. The parties to this Agreement acknowledge that clause (ii) of
the  foregoing  sentence  relates  only to  absolute  assignments  and  does not
prohibit assignments creating security interests, including, without limitation,
any pledge or assignment by any Lender of all or any portion of its rights under
this  Agreement and any Note to a Federal  Reserve  Bank;  provided that no such
pledge or assignment  creating a security  interest shall release the transferor
Lender from its obligations  hereunder unless and until the parties thereto have
complied with the provisions of Section 12.3. The Administrative Agent may treat
the Person which made any Loan or which holds any Note as the owner  thereof for
all purposes  hereof  unless and until such Person  complies  with Section 12.3;
provided that the  Administrative  Agent may in its discretion (but shall not be
required  to) follow  instructions  from the Person which made any Loan or which
holds  any Note to direct  payments  relating  to such  Loan or Note to  another
Person.  Any assignee of the rights to any Loan or any Note agrees by acceptance
of such  assignment  to be bound by all the  terms  and  provisions  of the Loan
Documents.  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 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 Loan.

     12.2     Participations.

     12.2.1   Permitted  Participants;  Effect.  Any Lender may, in the ordinary
course of its business and in accordance  with  applicable law, at any time sell
to one or more banks or other entities ("Participants")  participating interests
in any Loan owing to such Lender,  any Note held by such Lender,  any Commitment
of such Lender or any other interest of such Lender under the

                                      -55-

Loan  Documents.  In the  event of any such  sale by a Lender  of  participating
interests to a Participant,  such Lender's  obligations under the Loan Documents
shall remain unchanged, such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, such Lender shall remain
the  owner of its  Loans and the  holder  of any Note  issued to it in  evidence
thereof for all purposes under the Loan  Documents,  all amounts  payable by the
Borrower under this Agreement  (including under Article III) shall be determined
as if such Lender had not sold such  participating  interests,  and the Borrower
and the  Administrative  Agent shall  continue to deal solely and directly  with
such Lender in connection with such Lender's  rights and  obligations  under the
Loan Documents.

     12.2.2   Voting  Rights.  Each  Lender  shall   retain  the  sole  right to
approve, without the consent of any Participant, any amendment,  modification or
waiver  of any  provision  of the  Loan  Documents  other  than  any  amendment,
modification  or waiver  with  respect to any Loan or  Commitment  in which such
Participant  has an  interest  which  forgives  principal,  interest  or fees or
reduces  the  interest  rate or fees  payable  with  respect to any such Loan or
Commitment,  extends  the  Termination  Date,  postpones  any date fixed for any
regularly  scheduled  payment of principal  of, or interest or fees on, any such
Loan or  Commitment  or releases any Guarantor  from its  obligations  under the
Subsidiary Guaranty (except as provided in Section 8.4).

     12.3     Assignments.

     12.3.1   Permitted  Assignments.  Any Lender may, in the ordinary course of
its business and in accordance with applicable law, 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 Documents.  Such assignment shall be substantially in
the form of Exhibit C or in such  other form as may be agreed to by the  parties
thereto.  The  consents of the  Borrower  and the  Administrative  Agent  (which
consents shall not be unreasonably  withheld or delayed by any such party) shall
be  required  prior  to an  assignment  becoming  effective  with  respect  to a
Purchaser  which is not a Lender or an  Affiliate  thereof;  provided  that if a
Default has occurred and is continuing, the consent of the Borrower shall not be
required; provided, further, that no assignment shall be permitted if, as of the
date  thereof,  any  event or  circumstance  exists  which  would  result in the
Borrower being  obligated to pay any greater  amount  hereunder to the Purchaser
than the  Borrower  is  obligated  to pay to the  assigning  Lender.  Each  such
assignment  with  respect to a Purchaser  which is not a Lender or an  Affiliate
thereof  shall  (unless  each  of the  Borrower  and  the  Administrative  Agent
otherwise  consents) be in an amount not less than the lesser of (i)  $5,000,000
or (ii) the remaining amount of the assigning Lender's Commitment (calculated as
at the date of such assignment) or outstanding  Ratable Loans and participations
in Swing Line Loans (if the Commitments has been terminated).

     12.3.2   Effect; Effective  Date.  Upon (i) delivery to the  Administrative
Agent of an assignment,  together with any consents  required by Section 12.3.1,
and (ii) payment of a $4,000 fee to the Administrative Agent for processing such
assignment  (unless  such  fee is  waived  by the  Administrative  Agent),  such
assignment  shall  become  effective  on the  effective  date  specified in such
assignment.  The assignment shall contain a  representation  by the Purchaser to
the effect

                                      -56-

that none of the  consideration  used to make the purchase of the Commitment and
Loans under the applicable  assignment  agreement  constitutes  "plan assets" as
defined  under ERISA and that the rights and  interests of the  Purchaser in and
under the Loan Documents will not be "plan assets" under ERISA. On and after the
effective date of such  assignment,  such Purchaser  shall for all purposes be a
Lender party to this  Agreement  and any other Loan  Document  executed by or on
behalf of the Lenders and shall have all the rights and  obligations of a Lender
under the Loan  Documents,  to the same extent as if it were an  original  party
hereto,  and no further  consent or action by the  Borrower,  the Lenders or the
Administrative  Agent shall be required  to release the  transferor  Lender with
respect to the percentage of the Aggregate Commitment and Loans assigned to such
Purchaser.  Upon the  consummation of any assignment to a Purchaser  pursuant to
this Section 12.3.2, the transferor  Lender,  the  Administrative  Agent and the
Borrower shall, if the transferor Lender or the Purchaser desires that its Loans
be evidenced by Notes,  make  appropriate  arrangements so that new Notes or, as
appropriate,  replacement  Notes are  issued to such  transferor  Lender 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.

     12.4     Dissemination of Information.  The Borrower authorizes each Lender
to disclose to any  Participant  or Purchaser  or any other Person  acquiring an
interest in the Loan Documents by operation of law (each a "Transferee") and any
prospective  Transferee  any and all  information  in such  Lender's  possession
concerning the creditworthiness of the Borrower and its Subsidiaries,  including
without limitation any information contained in any Reports;  provided that each
Transferee and prospective Transferee agrees to be bound by Section 9.11 of this
Agreement.

     12.5     Tax Treatment. If any interest in any Loan Document is transferred
to any Transferee  which is organized under the laws of any  jurisdiction  other
than the United States or any State thereof,  the transferor  Lender shall cause
such Transferee, concurrently with the effectiveness of such transfer, to comply
with the provisions of Section 3.5(iv) and the Borrower shall not be required to
indemnify such Transferee  pursuant to Section 3.5 hereof for any Taxes withheld
as a result of the failure of the Transferee to so comply.

                                   ARTICLE XV

                     CHOICE OF LAW; CONSENT TO JURISDICTION;
                   WAIVER OF JURY TRIAL; MAXIMUM INTEREST RATE

     15.1     CHOICE OF LAW. THE LOAN  DOCUMENTS  (OTHER THAN THOSE CONTAINING A
CONTRARY  EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (INCLUDING,  WITHOUT  LIMITATION,  735 ILCS SECTION 105/5-1 ET
SEQ, BUT OTHERWISE  WITHOUT  REGARD TO THE CONFLICT OF LAWS  PROVISIONS)  OF THE
STATE OF  ILLINOIS,  BUT GIVING  EFFECT TO FEDERAL LAWS  APPLICABLE  TO NATIONAL
BANKS.

     15.2     CONSENT TO JURISDICTION.  THE BORROWER HEREBY IRREVOCABLY  SUBMITS
TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR ILLINOIS STATE
COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY  IRREVOCABLY  AGREES THAT
ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING  MAY BE HEARD AND  DETERMINED
IN ANY SUCH COURT AND IRREVOCABLY

                                      -58-

WAIVES ANY  OBJECTION IT MAY NOW OR  HEREAFTER  HAVE AS TO THE VENUE OF ANY SUCH
SUIT,  ACTION OR  PROCEEDING  BROUGHT  IN SUCH A COURT OR THAT SUCH  COURT IS AN
INCONVENIENT  FORUM.  NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE ADMINISTRATIVE
AGENT OR ANY LENDER TO BRING  PROCEEDINGS  AGAINST THE BORROWER IN THE COURTS OF
ANY OTHER  JURISDICTION.  ANY JUDICIAL  PROCEEDING  BY THE BORROWER  AGAINST THE
ADMINISTRATIVE  AGENT OR ANY LENDER OR ANY AFFILIATE OF THE ADMINISTRATIVE AGENT
OR ANY LENDER INVOLVING,  DIRECTLY OR INDIRECTLY,  ANY MATTER IN ANY WAY ARISING
OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN
A COURT IN CHICAGO, ILLINOIS.

     15.3     WAIVER OF JURY TRIAL. THE BORROWER, THE  ADMINISTRATIVE  AGENT AND
EACH LENDER  HEREBY  WAIVE TRIAL BY JURY IN ANY JUDICIAL  PROCEEDING  INVOLVING,
DIRECTLY  OR  INDIRECTLY,  ANY MATTER  (WHETHER  SOUNDING  IN TORT,  CONTRACT OR
OTHERWISE)  IN ANY WAY ARISING OUT OF,  RELATED TO, OR  CONNECTED  WITH ANY LOAN
DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

     15.4     Maximum  Interest Rate. No provision of the Loan  Documents  shall
require  the  payment  or permit the  collection  of  interest  in excess of the
maximum  permitted by applicable law ("Maximum Rate"). If any interest in excess
of the Maximum Rate is provided for or shall be  adjudicated  to be provided for
in the Notes or otherwise in connection with this  Agreement,  the provisions of
this  Section  15.4 shall  govern and prevail and neither the  Borrower  nor the
sureties,  guarantors,  successors or assigns of the Borrower shall be obligated
to pay the excess  amount of the  interest or any other  excess sum paid for the
use,  forbearance,  or detention of sums loaned. In the event the Administrative
Agent or any Lender ever receives, collects or applies as interest any amount in
excess of the Maximum Rate,  the amount by which such amount exceeds the Maximum
Rate  shall  be  applied  as  a  payment  and  reduction  of  the  principal  of
indebtedness  evidenced by the Loans,  and, if the principal amount of the Loans
has been paid in full,  any  remaining  excess  shall  forthwith  be paid to the
Borrower.

                                      -59-

     IN WITNESS WHEREOF, the Borrower,  the  Lenders,  the  Administrative Agent
and the  Syndication  Agent have  executed  this  Agreement as of the date first
above written.

     For the purposes of this Schedule,  the following  terms have the following
meanings, subject to the final paragraph of this Schedule:

     "Level I  Status"  exists  at any date if,  on such  date,  the  Borrower's
Moody's Rating is Baa1 or better or the Borrower's S&P Rating is BBB+ or better.

     "Level II Status" exists at any date if, on such date, (i) the Borrower has
not qualified for Level I Status and (ii) the Borrower's  Moody's Rating is Baa2
or better or the Borrower's S&P Rating is BBB or better.

     "Level III Status"  exists at any date if, on such date,  (i) the  Borrower
has not qualified for Level I Status or Level II Status and (ii) the  Borrower's
Moody's Rating is Baa3 or better or the Borrower's S&P Rating is BBB- or better.

     "Level IV Status" exists at any date if, on such date, (i) the Borrower has
not  qualified for Level I Status , Level II Status or Level III Status and (ii)
the  Borrower's  Moody's Rating is Ba1 or better or the Borrower's S&P Rating is
BB+ or better.

     "Level V Status"  exists at any date if, on such date, the Borrower has not
qualified  for Level I Status,  Level II Status,  Level III Status , or Level IV
Status.

     "Moody's Rating" means, at any time, the rating issued by Moody's Investors
Service, Inc. and then in effect with respect to the Borrower's senior unsecured
long-term public debt securities without third-party credit enhancement.

     "S&P Rating"  means,  at any time, the rating issued by Standard and Poor's

     The  Applicable  Margin  and  Commitment  Fee Rate shall be  determined  in
accordance with the foregoing table based on the Borrower's Status as determined
from its  then-current  Moody's and S&P Ratings.  The credit rating in effect on
any date for the  purposes  of this  Schedule  is that in effect at the close of
business on such date.  If at any time the Borrower has no Moody's  Rating or no
S&P Rating, Level V Status shall exist.

     If the Borrower is split-rated  and the ratings  differential is one level,
the higher  rating will apply.  If the Borrower is  split-rated  and the ratings
differential is two levels or more, the intermediate rating at the midpoint will
apply. If there is no midpoint,  the higher of the two intermediate ratings will
apply.

                                  SCHEDULE 5.13
                                   LITIGATION


On August 25, 2000,  a class action suit was filed  against the Borrower and its
subsidiaries in Sebastian County,  Arkansas, on behalf of all mineral owners who
own or owned a royalty and/or overriding  royalty interest in oil and gas leases
or other  agreements  in certain  sections of  Franklin  County,  Arkansas.  The
Borrower was granted authority in 1968 by the Arkansas Oil and Gas Commission to
operate a gas storage  facility in one  section of Franklin  County.  Based upon
subsequently  developed geological data, the Borrower sought authority to expand
this area and was granted  authority by the Arkansas Oil and Gas  Commission  to
operate gas storage in  additional  sections.  Plaintiffs  are  challenging  the
storage  agreements that the Borrower  obtained from the mineral interest owners
in 1968, 1999 and 2000 to operate the gas storage  facility known as "Stockton."
Plaintiffs allege various wrongful,  intentional and fraudulent acts relating to
the  operation  of the storage  pool  beginning  in 1968 and  continuing  to the
present and allege that the above-referenced  agreements from the mineral owners
were obtained  through  misrepresentation  and fraud. The Borrower has owned and
operated  the Stockton  storage  unit  through its Arkansas  Western Gas Company
subsidiary  until  1994,  at which time it was  transferred  to its  subsidiary,
SEECO,  Inc.  Plaintiffs claim ownership rights in the gas that the Borrower has
stored in the  storage  pool in an amount  in  excess  of $5  million  in actual
damages,  interest,  attorney's fees and punitive damages.  The Borrower and its
outside  counsel believe that this action is without merit and does not meet the
requirements for a class action.  The Borrower believes that plaintiffs claim to
the storage gas, which the Borrower has injected into the storage facility,  has
no merit and is not  supported by the Arkansas gas storage  statute  under which
the Borrower  operates  this  facility.  While the amount of this claim could be
significant,  management believes, based upon its investigation, that this claim
is without merit and that the Borrower's ultimate liability, if any, will not be
material to its consolidated  financial position, but in any one period it could
be significant to its results of operations.

                                                                  July 12, 2001


The Administrative Agent and the Lenders who are parties to the Credit Agreement
described below.


Gentlemen/Ladies:


     I am counsel for  Southwestern  Energy Company (the  "Borrower"),  and have
represented the Borrower and the Subsidiaries of the Borrower listed on Schedule
1 (the  "Guarantors")  in connection with its execution and delivery of a Credit
Agreement dated as of July 12, 2001 (the  "Agreement")  among the Borrower,  the
Lenders named therein, and Bank One, NA, as Administrative  Agent, and providing
for Advances in an aggregate principal amount not exceeding  $160,000,000 at any
one  time  outstanding.  All  capitalized  terms  used in this  opinion  and not
otherwise  defined  herein  shall have the  meanings  attributed  to them in the
Agreement.

     I  have  examined  the   Borrower's   and  each   Guarantor's   **[describe
constitutive  documents of Borrower and Guarantors and  appropriate  evidence of
authority to enter into the  transaction]**,  the Loan  Documents and such other
matters of fact and law which we deem necessary in order to render this opinion.
Based upon the foregoing, it is our opinion that:

     l.  Each of the Borrower and its Subsidiaries is a corporation, partnership
or limited liability company duly and properly incorporated or organized, as the
case may be,  validly  existing and (to the extent such concept  applies to such
entity) in good standing under the laws of its  jurisdiction of incorporation or
organization  and has all  requisite  authority  to conduct its business in each
jurisdiction in which its business is conducted.

     2.  The  execution  and delivery by the  Borrower and each Guarantor of the
Loan  Documents to which it is a party and the  performance  by the Borrower and
each Guarantor of its obligations thereunder have been duly authorized by proper
corporate or limited liability  company  proceedings on the part of the Borrower
and each Guarantor and will not:

             (a) require  any  consent  of  the  Borrower's  or any  Guarantor's
        shareholders or members (other than any such consent as has already been
        given and remains in full force and effect);

             (b) violate (i) any law, rule,  regulation,  order, writ, judgment,
        injunction,  decree  or  award  binding  on the  Borrower  or any of its
        Subsidiaries  or (ii) the  Borrower's


        or any Subsidiary's  articles or certificate of incorporation,  articles
        or certificate of organization, bylaws, or operating or other management
        agreement, as the case may be, or (iii) the provisions of any indenture,
        instrument or agreement to which the Borrower or any of its Subsidiaries
        is a party or is subject, or by which it, or its Property,  is bound, or
        conflict with or constitute a default thereunder; or

             (c) result in, or require,  the creation or  imposition of any Lien
        in, of or on the Property of the  Borrower or a  Subsidiary  pursuant to
        the terms of any  indenture,  instrument  or agreement  binding upon the
        Borrower or any of its Subsidiaries.

     3.  The Loan Documents  to which the  Borrower or any  Guarantor is a party
have been duly executed and delivered by the Borrower or such Guarantor,  as the
case may be, and constitute legal, valid and binding obligations of the Borrower
enforceable  against  the  Borrower  or such  Guarantor,  as the case may be, in
accordance with their terms except to the extent the enforcement  thereof may be
limited by bankruptcy,  insolvency or similar laws affecting the  enforcement of
creditors'  rights  generally and subject also to the  availability of equitable
remedies if equitable remedies are sought.

     4.  Except for the  litigation  disclosed in  Borrower's  Form 10-K for the
year ended  December  31, 2000 and  updated in the  Borrower's  most recent Form
10-Q, there  is  no   litigation,   arbitration,   governmental   investigation,
proceeding  or  inquiry  pending  or,  to the  best of  our knowledge  after due
inquiry,  threatened  against the  Borrower or  any of  its  Subsidiaries which,
if adversely determined, could reasonably be expected to have a Material Adverse
Effect.

     5.  No order, consent, adjudication,  approval, license,  authorization, or
validation of, or filing,  recording or  registration  with, or exemption by, or
other action in respect of any governmental or public body or authority,  or any
subdivision  thereof,  which has not been obtained by the Borrower or any of its
Subsidiaries,  is  required  to be  obtained  by  the  Borrower  or  any  of its
Subsidiaries  in  connection  with  the  execution  and  delivery  of  the  Loan
Documents,  the borrowings  under the Agreement,  the payment and performance by
the Borrower of the Obligations,  or the legality,  validity,  binding effect or
enforceability of any of the Loan Documents.

     This opinion may be relied upon by the  Administrative  Agent,  the Lenders
and their participants, assignees and other transferees.

                                                      Very truly yours,


                                    EXHIBIT C

                              ASSIGNMENT AGREEMENT

                                      NOTE
                                                                          [Date]

         Southwestern Energy Company, an Arkansas  corporation (the "Borrower"),
promises  to pay  to  the  order  of  ____________________________________  (the
"Lender") the aggregate  unpaid principal amount of all Loans made by the Lender
to the  Borrower  pursuant  to  Article  II of  the  Agreement  (as  hereinafter
defined),  in immediately  available funds at the main office of Bank One, NA in
Chicago, Illinois, as Administrative Agent, together with interest on the unpaid
principal  amount  hereof  at the  rates  and  on the  dates  set  forth  in the
Agreement.  The  Borrower  shall pay the  principal  of and  accrued  and unpaid
interest on the Loans in full on the Termination Date.

         The Lender shall,  and is hereby  authorized to, record on the schedule
attached  hereto,  or to otherwise record in accordance with its usual practice,
the date and  amount  of each  Loan and the date and  amount  of each  principal
payment hereunder.

         This Note is one of the Notes  issued  pursuant  to, and is entitled to
the benefits of, the Credit  Agreement  dated as of July 12, 2001 (which,  as it
may be amended or modified and in effect from time to time, is herein called the
"Agreement"),  among the  Borrower,  the lenders  party  thereto,  including the
Lender, and Bank One, NA, as Administrative  Agent, to which Agreement reference
is hereby made for a statement of the terms and conditions  governing this Note,
including the terms and  conditions  under which this Note may be prepaid or its
maturity date  accelerated.  This Note is guaranteed  pursuant to the Subsidiary
Guaranty,  as more  specifically  described in the Agreement.  Capitalized terms
used  herein  and not  otherwise  defined  herein  are used  with  the  meanings
attributed to them in the Agreement.

         Notwithstanding  anything to the contrary in this Note, no provision of
this Note shall  require  the  payment or permit the  collection  of interest in
excess of the maximum  permitted by  applicable  law  ("Maximum  Rate").  If any
interest in excess of the Maximum Rate is provided  for or shall be  adjudicated
to be so  provided,  in this  Note or  otherwise  in  connection  with  the loan
transaction,  the  provisions of this  paragraph  shall govern and prevail,  and
neither the Borrower nor the sureties, guarantors,  successors or assigns of the
Borrower  shall be  obligated  to pay the  excess of the  interest  or any other
excess sum paid for the use,  forbearance,  or detention of sums loaned.  If for
any reason  interest  in excess of the  Maximum  Rate  shall be deemed  charged,
required or permitted by any court of competent  jurisdiction,  the excess shall
be applied as payment and reduction of the principal of  indebtedness  evidenced
by this Note, and, if the principal  amount has been paid in full, any remaining
excess shall forthwith be paid to the Borrower.


         This Note shall be construed in accordance  with the internal laws (and
not the law of conflicts) of the State of Illinois, but giving effect to Federal
laws applicable to national banks.
