Fixed Rate  Advance,  not later than 10:30 a.m.,  New York time, on the proposed

Rate if the Borrower  rejects a Competitive Bid made at a lower  Competitive Bid
Rate,  (iii)  the  aggregate  amount of the  Competitive  Bids  accepted  by the

therein shall be promptly  remitted to the Agent;  any such amounts  received by
the Agent shall be promptly remitted by the Agent to the Lenders that shall have
made their payments  pursuant to this paragraph and to the Swingline  Lender, as

                                       20



     when Loans may be outstanding but new Loans may not be borrowed hereunder),
     then the Facility Fee shall  continue to accrue on the aggregate  principal
     amount of the  Revolving  Credit  Exposure of such Lender until such Lender
     ceases to have any Revolving Credit Exposure.

          2.7.2 Utilization Fee. If on any date the Aggregate Outstanding Credit
     Exposure  exceeds  thirty-three  and  one-third  percent  (331/3%)  of  the
     Aggregate  Commitment,  the Borrower  will pay to the Agent for the ratable
     benefit  of the  Lenders  based on their  Outstanding  Credit  Exposures  a
     utilization  fee (the  "Utilization  Fee") at a per annum rate equal to the

     Business Days' written notice to the Agent,  which notice shall specify the
     amount of any such  reduction,  provided,  however,  that the amount of the
     Aggregate  Commitment  may not be reduced below the  Aggregate  Outstanding
     Credit  Exposure.  All  accrued  facility  fees  shall  be  payable  on the
     effective date of any termination of the obligations of the Lenders to make
     Credit Extensions  hereunder and on the final date upon which all Revolving
     Loans are repaid.

     2.8.  Minimum Amount of Each Advance.  Each Eurodollar  Advance shall be in

Competitive Loan may be prepaid without the consent of the applicable Lender.

     2.10.  Method of  Selecting  Types and Interest  Periods for New  Revolving
Advances.  The Borrower  shall select the Type of Revolving  Advance and, in the
case of each  Revolving  Eurodollar  Advance,  the  Interest  Period  applicable
thereto  from time to time;  provided  that there shall be no more than five (5)
Interest  Periods in effect with  respect to all of the  Revolving  Loans at any
time, unless such limit has been waived by the Agent in its sole discretion. The
Borrower  shall give the Agent  irrevocable  notice (a  "Borrowing  Notice") not
later than 11:00 a.m.  (New

                                       21




York time) on the  Borrowing  Date of each  Revolving  Floating Rate Advance and
three  Business Days before the  Borrowing  Date for each  Revolving  Eurodollar
Advance, specifying:

     (i)  the Borrowing Date, which shall be a Business Day, of such Advance,

     (ii) the aggregate amount of such Advance,

     (iii) the Type of Advance selected, and

     (iv) in the case of each Eurodollar Advance, the Interest Period applicable
          thereto.

The Agent shall provide  written notice of each request for borrowing under this
Section 2.10 by 11:00 a.m. (New York time) (or, if later,  within one hour after
receipt of the applicable  Borrowing Notice from the Borrower) on each Borrowing
Date for each Floating  Rate Advance or on the third  Business Day prior to each
Borrowing Date for each Eurodollar Advance,  as applicable.  Not later than 1:00
p.m. (New York time) on each  Borrowing  Date,  each Lender shall make available
its  Revolving  Loan or  Revolving  Loans in Federal or other funds  immediately
available in New York to the Agent at its address specified  pursuant to Article
XIII.  The Agent  will  promptly  make the funds so  received  from the  Lenders
available to the Borrower at the Agent's aforesaid address.

     2.11.  Conversion and Continuation of Outstanding  Revolving  Advances;  No
Conversion or  Continuation  of Revolving  Eurodollar  Advances  After  Default.
Revolving Floating Rate Advances shall continue as Floating Rate Advances unless
and until such  Revolving  Floating Rate Advances are converted  into  Revolving
Eurodollar  Advances  pursuant to this Section 2.11 or are repaid in  accordance
with  Section  2.9.  Each  Revolving  Eurodollar  Advance  shall  continue  as a
Eurodollar  Advance  until  the  end  of the  then  applicable  Interest  Period
therefor, at which time such Revolving Eurodollar Advance shall be automatically
converted  into a Revolving  Floating  Rate  Advance  unless (x) such  Revolving
Eurodollar  Advance is or was repaid in  accordance  with Section 2.9 or (y) the
Borrower shall have given the Agent a Conversion/Continuation Notice (as defined
below)  requesting  that, at the end of such  Interest  Period,  such  Revolving
Eurodollar  Advance continue as a Revolving  Eurodollar  Advance for the same or
another Interest  Period.  Subject to the terms of Section 2.8, the Borrower may
elect from time to time to convert all or any part of a Revolving Advance of any
Type into any other Type or Types of Advances;  provided that any  conversion of
any Revolving  Eurodollar Advance shall be made on, and only on, the last day of
the Interest Period applicable thereto. Notwithstanding anything to the contrary
contained  in this  Section  2.11,  during  the  continuance  of a Default or an
Unmatured  Default,  the Agent may (or shall at the  direction  of the  Required
Lenders),  by notice to the Borrower,  declare that no Revolving  Advance may be
made,  converted or continued as a Eurodollar  Advance.  The Borrower shall give
the  Agent  irrevocable  notice  (a  "Conversion/Continuation  Notice")  of each
conversion  of a Revolving  Advance or  continuation  of a Revolving  Eurodollar
Advance not later than 11:00 a.m. (New York time) at least one (1) Business Day,
in the case of a conversion into a Revolving Floating Rate Advance, or three (3)
Business Days, in the case of a conversion  into or  continuation of a Revolving
Eurodollar  Advance,   prior  to  the  date  of  the  requested   conversion  or
continuation, specifying:

                                       22




     (i)  the requested date,  which shall be a Business Day, of such conversion
          or continuation,

     (ii) the aggregate  amount and Type of the Advance which is to be converted
          or continued, and

     (iii)the amount of such Advance which is to be converted  into or continued
          as a  Eurodollar  Advance  and the  duration  of the  Interest  Period
          applicable thereto.

This Section shall not apply to Competitive Loans or Swingline Loans,  which may
not be converted or continued.

     2.12.  Changes in Interest Rate, 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  automatically  converted  from a
Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.11, to but
excluding the date it is paid or is converted into a Eurodollar Advance pursuant
to Section 2.11 hereof,  at a rate per annum equal to the Floating Rate for such
day.  Changes in the rate of interest on that portion of any Advance  maintained
as a Floating Rate Advance 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 the
Interest Period  applicable  thereto to (but not including) the last day of such
Interest  Period at the Eurodollar Rate determined by the Agent as applicable to
such Eurodollar Advance based upon the Borrower's selections under Sections 2.10
and 2.11 and otherwise in accordance  with the terms hereof.  No Interest Period
may end after the Facility  Termination Date. Each Fixed Rate Advance shall bear
interest at the Fixed Rate applicable thereto.

     2.13. Rates  Applicable After Default.  During the continuance of a Default
(including the Borrower's  failure to pay any Loan when due, whether upon stated
maturity,  acceleration or otherwise) 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  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 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 7.6 or 7.7, the
interest  rates set forth in clauses (i) and (ii) above shall be  applicable  to
all Credit Extensions,  Advances,  fees and other Obligations  hereunder without
any election or action on the part of the Agent or any Lender.

     2.14. Method of Payment. All payments of the Obligations hereunder shall be
made, without setoff, deduction, or counterclaim, in immediately available funds
to the Agent at the Agent's  address  specified  pursuant to Article XIII, or at
any other Lending Installation of the Agent specified in writing by the Agent to
the  Borrower,  by 12:00  noon (New York time) on the date when due and shall be
applied  ratably by the Agent among the Lenders.  Each payment  delivered to the
Agent for the account of any Lender shall be delivered  promptly by the Agent to
such  Lender in the same type of funds that the Agent  received  at its  address
specified pursuant to

                                       23




Article XIII or at any Lending  Installation  specified in a notice  received by
the Agent from such Lender. The Agent is hereby authorized to charge the account
of the Borrower  maintained  with JPMCB for each payment of principal,  interest
and fees as it becomes due hereunder.

     2.15. 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 Agent shall also maintain accounts in which it will record (a) the
          date and the amount of each Loan made hereunder,  the Type thereof and
          the  Interest  Period  (in the  case of an  Eurodollar  Advance)  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,  (c) the  effective  date  and  amount  of each  Assignment
          Agreement  delivered  to and  accepted by it and the  parties  thereto
          pursuant to Section  12.3,  (d) the amount of any sum  received by the
          Agent hereunder from the Borrower and each Lender's share thereof, and
          (e) all other  appropriate  debits  and  credits as  provided  in this
          Agreement,  including, without limitation, all fees, charges, expenses
          and interest.

     (iii)The  entries  maintained  in  the  accounts   maintained  pursuant  to
          paragraphs  (i) and (ii) above  shall be prima facie  evidence  absent
          manifest error of the existence and amounts of the Obligations therein
          recorded;  provided,  however,  that the  failure  of the 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  promissory
          note in substantially the form of Exhibit E (a "Note"). In such event,
          the Borrower  shall  prepare,  execute and deliver to such Lender such
          Note  payable  to the  order of such  Lender.  Thereafter,  the  Loans
          evidenced by such Note and interest  thereon shall at all times (prior
          to any  assignment  pursuant to Section 12.3) be represented by one or
          more Notes payable to the order of the payee named therein,  except to
          the extent that any such Lender subsequently returns any such Note for
          cancellation  and requests  that such Loans once again be evidenced as
          described in paragraphs (i) and (ii) above.

     2.16.  Telephonic  Notices.  The Borrower hereby authorizes the Lenders and
the Agent to extend, convert or continue Advances, effect selections of Types of
Advances and to transfer funds based on telephonic notices made by any person or
persons the 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 and  Conversion/Continuation
Notices to be given  telephonically.  The Borrower agrees to deliver promptly to
the  Agent a written  confirmation,  signed by an  Authorized  Officer,  if such
confirmation is requested by the Agent or any Lender, of each telephonic notice.
If the written  confirmation  differs in any

                                       24




material respect from the action taken by the Agent and the Lenders, the records
of the Agent and the Lenders shall govern absent manifest error.

     2.17. Interest Payment Dates;  Interest and Fee Basis.  Interest accrued on
each  Floating  Rate Advance  shall be payable in arrears on each Payment  Date,
commencing with the first such date to occur after the Original  Effective Date,
on any date on which the  Floating  Rate  Advance  is  prepaid,  whether  due to
acceleration or otherwise, and at maturity.  Interest accrued on that portion of
the outstanding  principal amount of any Floating Rate Advance  converted into a
Eurodollar  Advance on a day other  than a Payment  Date shall be payable on the
date of conversion. Interest accrued on each Eurodollar Advance shall be payable
on the last day of its  applicable  Interest  Period,  on any date on which  the
Eurodollar  Advance is prepaid,  whether by  acceleration  or otherwise,  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 accrued on each Fixed
Rate Loan shall be payable on the last day of the Interest Period  applicable to
the  Advance  of which  such  Loan is a part  and,  in the case of a Fixed  Rate
Advance with an Interest Period of more than 90 days' duration (unless otherwise
specified in the applicable Competitive Bid Request), each day prior to the last
day of such Interest  Period that occurs at intervals of 90 days' duration after
the first day of such Interest Period, and any other dates that are specified in
the  applicable  Competitive  Bid Request as dates for payment of interest  with
respect  to such  Advance.  Interest  accrued  on each  Swingline  Loan shall be
payable on the day that such Loan is required to be repaid.  Interest accrued on
any Advance that is not paid when due shall be payable on demand and on the date
of payment in full. Interest on Eurodollar  Advances,  Fixed Rate Loans and fees
hereunder  shall be calculated for actual days elapsed on the basis of a 360-day
year.  Interest on Floating  Rate Advances  shall be calculated  for actual days
elapsed on the basis of a 365/366-day  year.  Interest  shall be payable for the
day an Advance is made but not for the day of any  payment on the amount paid if
payment is received prior to 12:00 noon (New York time) at the place of payment.
If any payment of principal of or interest on an Advance,  any fees or any other
amounts  payable to the Agent or any Lender  hereunder shall become due on a day
which is not a Business Day,  such payment shall be made on the next  succeeding
Business Day and, in the case of principal payment, such extension of time shall
be included in computing interest,  fees and commissions in connection with such
payment.

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

     2.19. 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 Agent and the Borrower in accordance


                                       25




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.

     2.20.  Non-Receipt of Funds by the Agent.  Unless the Borrower or a Lender,
as the  case  may be,  notifies  the  Agent  prior  to the  date on  which it is
scheduled  to make  payment  to the  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 Agent for the account of the  Lenders,  that it does not
intend to make such  payment,  the Agent may assume  that such  payment has been
made.  The 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 Agent,  the  recipient  of such payment  shall,  on demand by the
Agent,  repay to the 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 Agent until the date the 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.

     2.21.  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  Floating Rate 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 terminate or
replace the  Commitment  of such  Affected  Lender,  provided that no Default or
Unmatured  Default  shall have  occurred and be  continuing  at the time of such
termination or replacement,  and provided further that,  concurrently  with such
termination  or  replacement,  (i) if the  Affected  Lender  is being  replaced,
another bank or other entity which is  reasonably  satisfactory  to the Borrower
and the Agent shall agree, as of such date, to purchase for cash the Outstanding
Credit  Exposure of the  Affected  Lender  pursuant to an  Assignment  Agreement
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 immediately  available  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, in each case to the extent not paid by the purchasing lender
and (iii) if the Affected Lender is being terminated,  the Borrower shall pay to
such Affected Lender all Obligations due to such Affected Lender  (including the
amounts  described in the  immediately  preceding  clauses (i) and (ii) plus the
outstanding principal balance of such Affected Lender's Credit Extensions).

     2.22.  Extension of Facility  Termination Date.  Commencing with the second
anniversary of the Original  Effective  Date, the Borrower may annually  request
extensions  of the  Facility  Termination  Date by  submitting  a request for an
extension to the Agent (each,  an

                                       26




"Extension  Request") no more than  fifty-nine  (59) and no less than forty-five
(45) days  prior to each  anniversary  of the  Original  Effective  Date,  which
Extension Request shall specify (i) the new Facility  Termination Date requested
by the Borrower,  which new Facility  Termination Date shall be a date not later
than one year after the then current Facility Termination Date and (ii) the date
(which  date  must be not less  than 20 days  after  the  date of the  Extension
Request  and not less than 10 days  prior to the  anniversary  date  immediately
following  the date of such  Extension  Request)  as of which the  Lenders  must
respond to the Extension  Request (the  "Response  Date"),  and which  Extension
Request shall constitute a representation  and warranty by the Borrower that the
conditions  contained in Section 4.2 have been  satisfied as of the date of such
request and as of the then effective  Facility  Termination Date.  Promptly upon
receipt of an Extension Request,  the Agent shall notify each Lender thereof and
shall  request  each  Lender to  approve  the  Extension  Request.  Each  Lender
approving the Extension  Request shall deliver its written consent no later than
the Response Date (and the failure to provide such written  consent by such date
shall be deemed to be a decision not to extend) and the  Extension  Request,  if
approved,  shall become  effective on or after the date (the  "Effective  Date")
immediately  preceding the next anniversary of the Original  Effective Date. The
Commitment  of each Lender that declines to extend with respect to the Aggregate
Commitment  may, at the option of the Borrower,  be replaced in accordance  with
Section 12.3 (but only to the extent a replacement  Lender is then available) or
the  Aggregate  Commitment  reduced.  All  Obligations  due to each  Lender that
declines to extend its Commitment  under this Section 2.22 shall be paid in full
by the  Borrower  to the Agent for the  account of each such  Lender on the then
effective Facility Termination Date (without giving effect to any such requested
extension  thereto).  Lenders  representing  not less than 67% of the  Aggregate
Commitments  and the Borrower  must agree to any  extension  with respect to the
Facility  Termination Date for any such extension to become  effective,  and the
Agent shall  promptly  notify the  Borrower  and each Lender of any new Facility
Termination Date.

                                  ARTICLE III

                             YIELD PROTECTION; TAXES

     3.1. Yield  Protection.  If, on or after the Original  Effective  Date, the
adoption of any law or any governmental or quasi-governmental  rule, regulation,
policy,  guideline or directive (whether or not having the force of law), or any
change in any such law, rule, regulation,  policy,  guideline or directive or 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  compliance  by any  Lender  or
applicable  Lending  Installation with any request or directive  (whether or not
having  the  force of law) of any such  authority,  central  bank or  comparable
agency:

          3.1.1 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

          3.1.2   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 Lender or any applicable Lending


                                       27



     Installation  (other than  reserves and  assessments  taken into account in
     determining the interest rate applicable to Eurodollar Advances), or

          3.1.3  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 Commitment, Eurodollar Loans or Fixed Rate Loans
     or reduces any amount  receivable by any Lender or any  applicable  Lending
     Installation in connection with its Commitment,  Eurodollar  Loans or Fixed
     Rate Loans, or requires any Lender or any applicable  Lending  Installation
     to make any payment  calculated  by reference to the amount of  Commitment,
     Eurodollar Loans or Fixed Rate 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  Commitment,
Eurodollar  Loans or Fixed Rate Loans or to reduce the return  received  by such
Lender or applicable  Lending  Installation in connection with such  Commitment,
Eurodollar  Loans  or  Fixed  Rate  Loans,  then,  within  15  days  of  demand,
accompanied  by the written  statement  required by Section 3.6, 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.

     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,
accompanied  by the written  statement  required by Section 3.6, 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 Outstanding Credit
Exposure or its Commitment to make Revolving Loans hereunder  (after taking into
account such Lender's policies as to capital  adequacy).  "Change" means (i) any
change after the Original Effective Date in the Risk-Based Capital Guidelines or
(ii) any  adoption  of,  or  change  in,  or  change  in the  interpretation  or
administration  of any  other  law,  governmental  or  quasi-governmental  rule,
regulation,  policy,  guideline,  interpretation,  or directive  (whether or not
having the force of law) after the  Original  Effective  Date 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 Original  Effective Date,  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  Measurements  and  Capital  Standards,"
including transition rules, and any amendments to such regulations adopted prior
to the Original Effective Date.

     3.3.  Availability of Types of Advances.  If (x) any Lender 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 (y) the Required Lenders determine that (i) deposits
of a type and maturity  appropriate  to match fund  Eurodollar  Advances are not
available or (ii) the interest rate  applicable to Eurodollar  Advances

                                       28




does  not  accurately  reflect  the cost of  making  or  maintaining  Eurodollar
Advances,  or (iii) no reasonable  basis exists for  determining  the Eurodollar
Base Rate, then the Agent shall suspend the availability of Eurodollar  Advances
and require  any  affected  Eurodollar  Advances  to be repaid or  converted  to
Floating Rate Advances on the respective last days of the then current  Interest
Periods with respect to such Loans or within such earlier  period as required by
law, 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 or a
Fixed  Rate Loan  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 or continued,  a Fixed Rate Loan is not made or a
Floating Rate Advance is not converted  into a Eurodollar  Advance,  on the date
specified by the Borrower for any reason other than default by the Lenders, or a
Eurodollar  Advance or Fixed Rate Loan is not prepaid on the date  specified  by
the Borrower for any reason,  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 Advance or Fixed Rate Loan.

     3.5.  Taxes.  (i) All payments by the Borrower to or for the account of any
Lender or the 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 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 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 Agent
the  original  copy of a receipt  evidencing  payment  thereof  or, if a receipt
cannot be obtained with reasonable efforts, such other evidence of payment as is
reasonably  acceptable  to the  Agent,  in each case  within 30 days  after such
payment is made.

     (ii) In  addition,  the  Borrower  shall 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  shall  indemnify  the 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 Agent or such  Lender as a result of its  Commitment,
          any Credit Extensions made by it hereunder, or otherwise in connection
          with its participation in this Agreement and any liability  (including
          penalties,  interest and expenses)  arising  therefrom or with respect
          thereto.  Payments due under this indemnification shall be made within
          30 days of the date the Agent or such  Lender  makes  demand  therefor
          pursuant to Section  3.6.

                                       29




     (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 more than ten Business Days after the date on which
          it  becomes  a party  to this  Agreement  (but in any  event  before a
          payment is due to it  hereunder),  (i) deliver to each of the Borrower
          and the Agent two duly  completed  copies  of United  States  Internal
          Revenue Service Form W-8BEN or W-8ECI,  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,  or (ii) in the  case of a  Non-U.S.  Lender  that is  fiscally
          transparent,  deliver to the Agent a United  States  Internal  Revenue
          Form W-8IMY together with the applicable  accompanying  forms,  W-8 or
          W-9,  as the  case  may be,  and  certify  that it is  entitled  to an
          exemption  from United States  withholding  tax. Each Non-U.S.  Lender
          further  undertakes  to deliver to each of the  Borrower and the 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 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 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 clause (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 such
          Non-U.S.  Lender  became a party  to this  Agreement),  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 clause (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 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.

                                       30




     (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 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  Agent of a  change  in
          circumstances   which   rendered  its   exemption   from   withholding
          ineffective, or for any other reason), such Lender shall indemnify the
          Agent fully for all amounts paid, directly or indirectly, by the Agent
          as tax, withholding  therefor,  or otherwise,  including penalties and
          interest,  and including taxes imposed by any  jurisdiction on amounts
          payable  to  the  Agent  under  this  subsection,  together  with  all
          reasonable  costs and expenses related thereto  (including  attorneys'
          fees and time charges of attorneys for the Agent,  which attorneys may
          be employees of the 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. Each Lender shall deliver a
written  statement of such Lender to the Borrower  (with a copy to the 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 final,  conclusive and binding on the
Borrower in the absence of manifest error,  and upon  reasonable  request of the
Borrower, such Lender shall promptly provide supporting documentation describing
and/or evidence of the applicable event giving rise to such amount to the extent
not inconsistent with such Lender's policies or applicable law. 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,  currency and maturity  corresponding  to the
deposit used as a reference in  determining  the Eurodollar  Rate  applicable to
such Loan,  whether in fact that is the case or not. Unless  otherwise  provided
herein,  the amount  specified  in the written  statement of any Lender shall be
payable on demand after receipt by the Borrower of such written  statement.  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.

     3.7. Alternative Lending  Installation.  To the extent reasonably possible,
each Lender shall designate an alternate  Lending  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 judgment
of such Lender,  disadvantageous  to such Lender.  A Lender's  designation of an
alternative  Lending  Installation  shall not affect the Borrower's rights under
Section 2.21 to replace a Lender.

                                   ARTICLE IV

                              CONDITIONS PRECEDENT

     4.1.  Restatement  Effective  Date.  The amendment and  restatement  of the
Pre-Restatement  Credit  Agreement by this Agreement shall not become  effective
unless the following  conditions  precedent have been satisfied and the Borrower
has furnished to the Agent with sufficient copies for the Lenders:


                                       31



          4.1.1  Counterparts of this Agreement that, when taken together,  bear
     the signatures of the Borrower, the Agent and the Required Lenders.

          4.1.2 A certificate,  signed by the Treasurer of the Borrower, stating
     that on the Restatement  Effective Date (a) no Default or Unmatured Default
     has  occurred  and  is  continuing,  (b)  all of  the  representations  and
     warranties in Article V shall be true and correct in all material  respects
     as of such  date  and  (c) no  material  adverse  change  in the  business,
     financial  condition or  operations  of the Borrower and its  Subsidiaries,
     taken as a whole,  has  occurred  since  December  31,  2003 except for the
     Disclosed Matters.

          4.1.3  Such other  documents  as any  Lender or its  counsel  may have
     reasonably requested.

     4.2. Each Credit  Extension.  The Lenders shall not be required to make any
Credit Extension unless on the applicable Credit Extension Date:

          4.2.1 There exists no Default or Unmatured Default.

          4.2.2 The  representations  and warranties  contained in Article V are
     true and correct as of such Credit  Extension Date except to the extent any
     such  representation  or warranty is stated to relate  solely to an earlier
     date, in which case such  representation  or warranty  shall have been true
     and correct on and as of such earlier date.

          4.2.3 All legal  matters  incident to the making of such Advance shall
     be satisfactory to the Lenders and their counsel.

          4.2.4 In the case of any  Credit  Extension  which  would  (i) be made
     after  June  30,  2007,  (ii)  cause  the  aggregate  principal  amount  of
     short-term Indebtedness of the Borrower to exceed $1,500,000,000,  or (iii)
     cause the aggregate principal amount of issuances and sales by the Borrower
     of capital stock,  preferred stock,  the other securities  specified in the
     Securities  and Exchange  Commission  order referred to in Section 5.18 and
     long-term  Indebtedness  to exceed  $2,500,000,000,  such Credit  Extension
     shall have been duly  authorized by an order of the Securities and Exchange
     Commission  and the Agent shall have  received a true and complete  copy of
     such order authorizing such Credit Extension.

     Each  Borrowing  Notice with  respect to each such Credit  Extension  shall
constitute a  representation  and warranty by the Borrower  that the  conditions
contained in Sections 4.2.1,  4.2.2,  4.2.3 and 4.2.4 have been  satisfied.  Any
Lender may require a duly completed compliance  certificate in substantially the
form of Exhibit B as a condition to making a Credit Extension.

                                   ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

     The  Borrower  represents  and  warrants to each Lender and the Agent as of
each of (i) the Restatement  Effective Date, (ii) the date of the initial Credit
Extension hereunder after the

                                       32



Restatement  Effective Date (if different from the  Restatement  Effective Date)
and (iii) each date as required by Section 4.2:

     5.1. Existence and Standing. Each of the Borrower and its Subsidiaries is a
corporation, partnership (in the case of Subsidiaries only) 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.

     5.2.  Authorization and Validity.  The Borrower has the power and authority
and legal right to execute and  deliver  the Loan  Documents  and to perform its
obligations  thereunder.  The execution and delivery by the Borrower of the Loan
Documents  and the  performance  of its  obligations  thereunder  have been duly
authorized by proper  proceedings,  and the Loan Documents to which the Borrower
is a party  constitute  legal,  valid and binding  obligations  of the  Borrower
enforceable  against the  Borrower in  accordance  with their  terms,  except as
enforceability  may  be  limited  by  (i)  bankruptcy,   insolvency,  fraudulent
conveyances,  reorganization  or  similar  laws  relating  to or  affecting  the
enforcement of creditors'  rights generally;  (ii) general equitable  principles
(whether  considered in a proceeding in equity or at law) and (iii) requirements
of reasonableness, good faith and fair dealing.

     5.3. No Conflict; Government Consent. Neither the execution and delivery by
the Borrower of the Loan Documents,  nor the  consummation  of the  transactions
therein  contemplated,  nor compliance with the provisions  thereof will 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,  partnership
agreement, certificate of partnership,  articles or certificate of organization,
by-laws, or operating agreement 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 under,
or 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 such
indenture,  instrument or agreement. 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 this 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.

     5.4.  Financial  Statements.  The December 31, 2003 consolidated  financial
statements of the Borrower and its Subsidiaries  included in the Borrower's Form
10-K  for  the  fiscal  year  ended  December  31,  2003,  the  March  31,  2004
consolidated  financial statements of the Borrower and its Subsidiaries included
in the Borrower's  Form 10-Q for the quarterly  period ended March 31, 2004, and
the June 30, 2004  consolidated  financial  statements  of the  Borrower and its
Subsidiaries included in the Borrower's Form 10-Q for the quarterly period ended
June 30, 2004

                                       33




heretofore  delivered to the Agent and the Lenders,  in each case, were prepared
in accordance  with generally  accepted  accounting  principles in effect on the
date such  statements  were  prepared  (except for the absence of footnotes  and
subject to year end audit  adjustments)  and  fairly  present  the  consolidated
financial  condition and operations of the Borrower and its Subsidiaries at such
date and the consolidated results of their operations for the period then ended.

     5.5.  Material  Adverse Change.  Since December 31, 2003, 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 (a "Material Adverse Change"), except
for the  Disclosed  Matters;  provided,  however,  that  neither (i) any ratings
downgrade  applicable  to  the  Indebtedness  of  the  Borrower  or  any  of its
Subsidiaries  by  Moody's  or  S&P  nor  (ii)  the  Borrower's  or  any  of  its
Subsidiaries' inability to place commercial paper in the capital markets, shall,
in and of themselves, be deemed events constituting a Material Adverse Change.

     5.6. Taxes. The Borrower and its Subsidiaries (and to the best knowledge of
the Borrower with respect to entities  acquired  pursuant to the IP  Acquisition
and  taxable  periods  ending on or before  January 1, 2003 for  CILCORP and its
subsidiaries) have filed all United States federal tax returns and all other tax
returns  which are  required to be filed and have paid all taxes due pursuant to
said  returns or pursuant to any  assessment  received by the Borrower or any of
its  Subsidiaries,  except  in  respect  of such  taxes,  if any,  as are  being
contested in good faith and as to which adequate  reserves have been provided in
accordance with Agreement  Accounting  Principles and as to which no Lien exists
(except as  permitted  by Section  6.13.1).  The  Internal  Revenue  Service has
completed  audits of the United States federal income tax returns filed by Union
Electric for all periods  through the calendar  taxable year ending December 31,
1997 and by CIPSCO,  Inc.  for all periods  through the  calendar  taxable  year
ending December 31, 1997. The Internal  Revenue Service has not completed audits
of the United  States  federal  income tax returns filed by the Borrower and its
Subsidiaries for subsequent periods. No claims have been, or are being, asserted
with  respect to such taxes that could  reasonably  be  expected  to result in a
Material Adverse Effect and no liens have been filed with respect to such taxes.
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.

     5.7.  Litigation  and  Contingent  Obligations.  Other  than the  Disclosed
Matters,  there  is  no  litigation,  arbitration,  governmental  investigation,
proceeding  or inquiry  pending or, to the  knowledge of any of their  officers,
threatened  against or affecting the Borrower or any of its  Subsidiaries  which
could, if determined  adversely to the Borrower or its Subsidiaries,  reasonably
be expected to have a Material Adverse Effect or which seeks to prevent,  enjoin
or delay the  making of any  Loans.  Other than any  liability  incident  to any
litigation,  arbitration or proceeding which could not reasonably be expected to
have  a  Material  Adverse  Effect,  the  Borrower  has no  material  contingent
obligations not provided for or disclosed in the financial  statements  referred
to in Section 5.4.

     5.8. Subsidiaries. Schedule 1 contains an accurate list of all Subsidiaries
of the Borrower as of the date of this Agreement, setting forth their respective
jurisdictions  of organization  and the percentage of their  respective  capital
stock or other ownership  interests

                                       34



owned by the Borrower or other  Subsidiaries.  All of the issued and outstanding
shares of capital stock or other ownership  interests of such  Subsidiaries have
been (to the extent such  concepts are relevant  with respect to such  ownership
interests) duly authorized and issued and are fully paid and non-assessable.

     5.9. ERISA. No ERISA Event has occurred or is reasonably  expected to occur
that,  when taken together with all other ERISA Events that have occurred or are
reasonably  expected  to occur,  could  reasonably  be  expected  to result in a
Material Adverse Effect.

     5.10.  Accuracy  of  Information.  The  information,  exhibits  or  reports
furnished by the Borrower to the Agent or to any Lender in  connection  with the
negotiation of, or compliance  with, the Loan Documents as of the date furnished
do not contain  any  material  misstatement  of fact or omit to state a material
fact or any  fact  necessary  to  make  the  statements  contained  therein  not
misleading.

     5.11.  Regulation  U. Neither the Borrower nor any of its  Subsidiaries  is
engaged principally,  or as one of its important activities,  in the business of
extending credit for the purpose,  whether immediate,  incidental or ultimate of
buying or carrying margin stock (as defined in Regulation U), and after applying
the  proceeds  of each  Advance,  margin  stock (as  defined  in  Regulation  U)
constitutes  less than 25% of the value of those  assets of the Borrower and its
Subsidiaries  which are subject to any limitation on sale,  pledge, or any other
restriction hereunder.

     5.12.  Material  Agreements.  Neither the Borrower nor any  Subsidiary is a
party  to any  agreement  or  instrument  or  subject  to any  charter  or other
corporate  restriction  which  could  reasonably  be expected to have a Material
Adverse  Effect as  described  in clauses  (ii) and/or  (iii) of the  definition
thereof.  Neither  the  Borrower  nor  any  Subsidiary  is  in  default  in  the
performance,  observance or fulfillment of any of the obligations,  covenants or
conditions  contained in (i) any agreement or instrument 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,  which
default could be reasonably expected to have a Material Adverse Effect.

     5.13.  Compliance With Laws. Except for the Disclosed Matters, the Borrower
and  its  Subsidiaries  have  complied  with  all  applicable  statutes,  rules,
regulations,  orders and  restrictions of any domestic or foreign  government or
any  instrumentality  or agency thereof having  jurisdiction over the conduct of
their respective  businesses or the ownership of their respective Property which
non-compliance  therewith  could  reasonably be expected to result in a Material
Adverse Effect.

     5.14. Ownership of Properties.  On the date of this Agreement, the Borrower
and its Subsidiaries  have good title (except for minor defects in title that do
not  interfere  with their  ability  to  conduct  their  business  as  currently
conducted or to utilize such properties for the intended purposes),  free of all
Liens other than those  permitted by Section 6.13, to all of the assets material
to the Borrower's  business reflected in the Borrower's most recent consolidated
financial  statements  provided to the Agent,  as owned by the  Borrower and its
Subsidiaries.

                                       35




     5.15. Plan Assets;  Prohibited Transactions.  The Borrower is not an entity
deemed to hold "plan assets" within the meaning of 29 C.F.R.  ss.  2510.3-101 of
an employee  benefit plan (as defined in Section 3(3) of ERISA) which is subject
to Title I of ERISA or any plan  (within  the  meaning  of  Section  4975 of the
Code), and assuming the accuracy of the  representations  and warranties made in
Section 9.12 and in any assignment made pursuant to Section 12.3.3,  neither the
execution of this  Agreement nor the making of Loans  hereunder  gives rise to a
prohibited  transaction  within the  meaning of Section  406 of ERISA or Section
4975 of the Code.

     5.16.  Environmental  Matters. In the ordinary course of its business,  the
officers  of the  Borrower  consider  the  effect of  Environmental  Laws on the
business  of the  Borrower  and its  Subsidiaries,  in the  course of which they
identify and evaluate  potential risks and liabilities  accruing to the Borrower
due to Environmental Laws. On the basis of this consideration,  the Borrower has
concluded  that,  other than the Disclosed  Matters,  Environmental  Laws cannot
reasonably  be  expected  to have a  Material  Adverse  Effect.  Except  for the
Disclosed  Matters,   and  except  with  respect  to  any  other  matters  that,
individually or in the aggregate,  could not reasonably be expected to result in
a Material Adverse Effect,  neither the Borrower nor any Subsidiary has received
any notice to the effect that its operations are not in material compliance with
any of the requirements of applicable  Environmental  Laws or are the subject of
any federal or state  investigation  evaluating  whether any remedial  action is
needed to respond to a release of any toxic or hazardous waste or substance into
the environment.

     5.17. Investment Company Act. Neither the Borrower nor any Subsidiary is an

that all such Indebtedness be issued on or before June 30, 2007 and, in the case
of  short-term  Indebtedness,  mature  not later  than 364 days  thereafter.  An
additional  authorization  from the Securities and Exchange  Commission  will be
necessary in order for the Borrower, after June 30, 2007, to obtain any Advances

all  their  Property  in  such  amounts,   subject  to  such   deductibles   and
self-insurance   retentions  and  covering  such  properties  and  risks  as  is
consistent with sound business practice.

                                  ARTICLE VIII

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

     8.1.  Acceleration.  If any Default  described in Section 7.6 or 7.7 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 Agent
or any Lender.  If any other Default occurs,  the Required Lenders (or the 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, 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 7.6 or 7.7 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 Agent  shall,  by notice to the
Borrower, rescind and annul such acceleration and/or termination.

     8.2.  Amendments.  Subject  to the  provisions  of this  Section  8.2,  the
Required  Lenders  (or the Agent with the  consent  in  writing of the  Required
Lenders) and the Borrower may enter into agreements  supplemental hereto for the
purpose of adding or modifying any  provisions to

                                       46



the Loan  Documents  or  changing in any manner the rights of the Lenders or the
Borrower hereunder or thereunder or waiving any Default hereunder or thereunder;
provided,  however,  that no such  supplemental  agreement  shall,  without  the
consent of all of the Lenders:

          8.2.1 Extend the final maturity of any Loan or postpone any payment of
     principal 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  (other than (i) a waiver of the  application  of the default
     rate of interest pursuant to Section 2.13 hereof and (ii) extensions of the
     Facility Termination Date pursuant to Section 2.22).

          8.2.2  Waive  any  condition  set forth in  Section  4.2,  reduce  the
     percentage  specified in the  definition  of Required  Lenders or any other
     percentage  of Lenders  specified to be the  applicable  percentage in this
     Agreement to act on specified  matters or amend the definition of "Pro Rata
     Share".

          8.2.3 Other than as expressly  permitted by the terms of Section 2.22,
     extend the Facility  Termination  Date,  or reduce the amount or extend the
     payment date for, the  mandatory  payments  required  under Section 2.2, or
     increase the amount of the  Commitment of any Lender  hereunder,  or permit
     the Borrower to assign its rights or  obligations  under this  Agreement or
     change  Section  2.14 or 2.7.3 in a manner  that  would  alter the pro rata
     sharing of payments or reduction of commitments required thereby.

          8.2.4 Amend this Section 8.2.

No amendment of any  provision  of this  Agreement  relating to the Agent or the
Swingline Lender shall be effective  without the written consent of the Agent or
the Swingline Lender, as the case may be. The Agent may waive payment of the fee
required under Section  12.3.3 without  obtaining the consent of any other party
to  this  Agreement.  Notwithstanding  the  foregoing,  any  provision  of  this
Agreement  may be  amended  by an  agreement  in  writing  entered  into  by the
Borrower,  the  Required  Lenders  and the  Agent  if (i) by the  terms  of such
agreement  any  remaining  Commitment  of  each  Lender  not  consenting  to the
amendment  provided for therein shall terminate upon the  effectiveness  of such
amendment and (ii) at the time such amendment becomes effective, each Lender not
consenting  thereto  receives  payment in full of the  principal of and interest
accrued on each Advance made by it and all other  amounts owing to it or accrued
for its account under this Agreement.

     8.3.  Preservation  of Rights.  No delay or  omission of the Lenders or the
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 Credit  Extension  notwithstanding  the  existence  of a Default  or
Unmatured  Default or the  inability of the  Borrower to satisfy the  conditions
precedent  to  such  Credit   Extension  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, or by the Agent with the consent of, the requisite  number of Lenders
required  pursuant to Section  8.2,  and then only to the extent in such writing
specifically set forth.  All


                                       47



remedies  contained in the Loan Documents or by law afforded shall be cumulative
and all  shall be  available  to the  Agent  and the  Lenders  until  all of the
Obligations have been paid in full.

                                   ARTICLE IX

                               GENERAL PROVISIONS

     9.1. Survival of Representations. All representations and warranties of the
Borrower  contained  in this  Agreement  shall  survive the making of the Credit
Extensions 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.

     9.3.  Headings.  Section headings in the Loan Documents are for convenience
of  reference  only,  and  shall not  govern  the  interpretation  of any of the
provisions of the Loan Documents.

     9.4. Entire  Agreement.  The Loan Documents embody the entire agreement and
understanding  among the  Borrower,  the Agent and the Lenders and supersede all
prior  agreements  and  understandings  among  the  Borrower,  the Agent and the
Lenders relating to the subject matter thereof other than those contained in the
fee letter  described  in Section  10.13 which shall  survive and remain in full
force and effect during the term of this Agreement.

     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
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,  however,  that the parties
hereto  expressly  agree that each  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.

     9.6. Expenses; Indemnification.  (i) The Borrower shall reimburse the Agent
and each Arranger for any reasonable  costs,  internal charges and out-of-pocket
expenses (including  reasonable attorneys' and paralegals' fees and time charges
of attorneys  for the Agent,  which  attorneys may be employees of the Agent and
expenses of and fees for other advisors and  professionals  engaged by the Agent
or such  Arranger)  paid or incurred by the Agent or such Arranger in connection
with the  investigation,  preparation,  negotiation,  documentation,  execution,
delivery,  syndication,  distribution  (including,  without limitation,  via the
internet),  review,  amendment,  modification  and  administration  of the  Loan
Documents.  The Borrower also agrees to reimburse  the Agent,  each Arranger and
the  Lenders  for  any  costs,  internal  charges  and  out-of-pocket   expenses
(including  attorneys'  and  paralegals'  fees and time  charges and expenses of
attorneys and  paralegals  for the Agent,  such Arranger and the Lenders,  which

                                       48




attorneys  and  paralegals  may be employees of the Agent,  such Arranger or the
Lenders)  paid  or  incurred  by the  Agent,  such  Arranger  or any  Lender  in
connection with the collection and enforcement of the Loan Documents.

     (ii) The  Borrower  hereby  further  agrees to  indemnify  the Agent,  each
          Arranger, each Lender, their respective affiliates,  and each of their
          directors, officers and employees against all losses, claims, damages,
          penalties,  judgments,  liabilities and expenses  (including,  without
          limitation, all expenses of litigation or preparation therefor whether
          or not the Agent, any Arranger, any Lender or any affiliate is a party
          thereto,  and all attorneys' and  paralegals'  fees,  time charges and
          expenses  of   attorneys   and   paralegals   of  the  party   seeking
          indemnification,  which  attorneys  and  paralegals  may or may not be
          employees of such party seeking indemnification) 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  have  resulted,  as
          determined in a final non-appealable  judgment by a court of competent
          jurisdiction,  from the gross negligence or willful  misconduct of the
          party seeking  indemnification.  The obligations of the Borrower under
          this Section 9.6 shall survive the termination of this Agreement.

     (iii)To the extent that the  Borrower  fails to pay any amount  required to
          be paid by it to the Agent,  the  Arrangers  or the  Swingline  Lender
          under  paragraph  (i) or (ii) of this Section,  each Lender  severally
          agrees to pay to the Agent, the Arrangers or the Swingline  Lender, as
          the case may be, such  Lender's Pro Rata Share  (determined  as of the
          time that the applicable  unreimbursed expense or indemnity payment is
          sought) of such unpaid amount;  provided that the unreimbursed expense
          or indemnified loss, claim,  damage,  liability or related expense, as
          the case may be, was  incurred by or asserted  against the Agent,  the
          Arrangers or the Swingline Lender in its capacity as such.

     9.7. Numbers of Documents. All statements,  notices, closing documents, and
requests hereunder shall be furnished to the Agent with sufficient  counterparts
so that the Agent may furnish one to each of the Lenders, to the extent that the
Agent deems necessary.

     9.8. Accounting.  Except as provided to the contrary herein, all accounting
terms  used in the  calculation  of any  financial  covenant  or test  shall  be
interpreted  and all accounting  determinations  hereunder in the calculation of
any  financial  covenant  or test  shall be made in  accordance  with  Agreement
Accounting   Principles.   If  any  changes  in  generally  accepted  accounting
principles  are hereafter  required or permitted and are adopted by the Borrower
or any of its  Subsidiaries  with the  agreement  of its  independent  certified
public  accountants  and such  changes  result  in a  change  in the  method  of
calculation of any of the financial covenants,  tests, restrictions or standards
herein  or in  the  related  definitions  or  terms  used  therein  ("Accounting
Changes"),  the parties hereto agree, at the Borrower's  request,  to enter into
negotiations,  in good  faith,  in order to amend  such  provisions  in a credit
neutral  manner so as to reflect  equitably such changes with the desired result
that the criteria for evaluating the Borrower's and its Subsidiaries'  financial
condition  shall be the same after such  changes as if such changes had not

                                       49




been made;  provided,  however,  until such  provisions  are amended in a manner
reasonably  satisfactory  to the Agent and the Required  Lenders,  no Accounting
Change shall be given effect in such  calculations.  In the event such amendment
is entered  into,  all  references  in this  Agreement to  Agreement  Accounting
Principles shall mean generally accepted accounting principles as of the date of
such amendment.  Notwithstanding the foregoing,  all financial  statements to be
delivered  by the  Borrower  pursuant  to  Section  6.1  shall  be  prepared  in
accordance with generally accepted accounting principles in effect at such time.

     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 Agent on the other hand shall be solely that of
borrower and lender.  Neither the Agent,  any Arranger nor any Lender shall have
any fiduciary  responsibilities to the Borrower. Neither the Agent, any Arranger
nor 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 neither the Agent, any Arranger
nor 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. Neither the Borrower, the Agent, any Arranger nor any Lender
shall have any liability with respect to, and each of the Agent,  each Arranger,
each Lender and the Borrower hereby waives,  releases and agrees not to sue for,
any  special,  indirect,  consequential  or punitive  damages  suffered by it 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 its Affiliates and to other Lenders and
their respective Affiliates,  for use solely in connection with the transactions
contemplated hereby, (ii) to legal counsel,  accountants, and other professional
advisors  to such  Lender  or to a  Transferee,  in each  case  which  have been
informed as to the confidential  nature of such  information,  for use solely in
connection  with the  transactions  contemplated  hereby,  (iii)  to  regulatory
officials  having  jurisdiction  over it, (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,  (vi) to such  Lender's  direct or
indirect  contractual  counterparties  in swap  agreements or to legal  counsel,
accountants and other professional advisors to such counterparties, in each case
which have been  informed  as to the  confidential  nature of such  information,
(vii)  permitted by Section  12.4 and (viii) to rating  agencies if requested or
required by such agencies in connection  with a rating  relating to the Advances
hereunder.

                                       50



     9.12. Lenders Not Utilizing Plan Assets.  Each Lender and Designated Lender
represents  and warrants that none of the  consideration  used by such Lender or
Designated  Lender to make its Loans  constitutes  for any  purpose  of ERISA or
Section  4975 of the Code  assets of any "plan" as  defined  in Section  3(3) of
ERISA or Section 4975 of the Code and the rights and interests of such Lender or
Designated  Lender in and under the Loan  Documents  shall not  constitute  such
"plan assets" under ERISA.

     9.13. Nonreliance.  Each Lender hereby represents that it is not relying on
or looking to any margin stock (as defined in Regulation U) as collateral in the
extension or maintenance of the credit provided for herein.

     9.14. Disclosure. The Borrower and each Lender hereby acknowledge and agree
that each Lender and its Affiliates  from time to time may hold  investments in,
make  other  loans to or have  other  relationships  with the  Borrower  and its
Affiliates.

     9.15.  USA Patriot Act.  Each Lender and each Issuing Bank hereby  notifies
the Borrower  that  pursuant to the  requirements  of the USA Patriot Act, it is
required to obtain,  verify and record information that identifies the Borrower,
which  information  includes  the name and  address  of the  Borrower  and other
information  that will allow such Lender to identify the Borrower in  accordance
with its requirements.

                                    ARTICLE X

                                    THE AGENT

     10.1.  Appointment;  Nature of  Relationship.  JPMCB is hereby appointed by
each of the Lenders as its contractual representative (herein referred to as the
"Agent")  hereunder and under each other Loan Document,  and each of the Lenders
irrevocably  authorizes the 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 Agent agrees to act as such contractual representative
upon the express conditions contained in this Article X. Notwithstanding the use
of the defined  term  "Agent," it is  expressly  understood  and agreed that the
Agent shall not have any fiduciary  responsibilities  to any Lender by reason of
this Agreement or any other Loan Document and that the 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  Lenders'  contractual  representative,  the Agent (i) does not
hereby  assume  any  fiduciary  duties  to  any  of  the  Lenders,   (ii)  is  a
"representative"  of the Lenders within the meaning of the term "secured  party"
as defined  in the New York  Uniform  Commercial  Code and (iii) 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 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 Agent shall have and may exercise such powers under the
Loan Documents as are  specifically  delegated to the Agent by the terms of each
thereof,  together with such powers as are reasonably  incidental  thereto.  The
Agent shall have no implied  duties or


                                       51



fiduciary  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 Agent.

     10.3.  General  Immunity.  Neither  the  Agent  nor  any of its  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 Agent nor any
of its 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
receipt of items required to be delivered solely to the 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;  (f) the
value,  sufficiency,  creation,  perfection  or  priority  of  any  Lien  in any
collateral  security;  or (g) the  financial  condition  of the  Borrower or any
guarantor  of any of the  Obligations  or of any of the  Borrower's  or any such
guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to
the Lenders  information that is not required to be furnished by the Borrower to
the Agent at such time,  but is  voluntarily  furnished  by the  Borrower to the
Agent (either in its capacity as Agent or in its individual capacity).

     10.5.  Action on Instructions  of Lenders.  The 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 all of the Lenders in the event that and to the extent that
this Agreement  expressly  requires such), 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 Agent shall be under no 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  (or all of the  Lenders in the event
that and to the extent that this Agreement  expressly  requires such). The 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  in writing by the Lenders pro rata against any and all  liability,
cost and expense that it may incur by reason of taking or continuing to take any
such action.

     10.6.  Employment  of Agents and Counsel.  The Agent may execute any of its
duties  as 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 misconduct  of any such agents or  attorneys-in-fact
selected by it with  reasonable  care.  The Agent shall be entitled to advice of


                                       52



counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters  pertaining to the Agent's duties  hereunder and under any other
Loan Document.

     10.7. Reliance on Documents;  Counsel.  The 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 Agent, which counsel
may be employees of the Agent.

     10.8.  Agent's  Reimbursement  and  Indemnification.  The Lenders  agree to
reimburse and indemnify the Agent ratably in proportion to the Lenders' Pro Rata
Shares of the Aggregate  Commitment  (or, if the Aggregate  Commitment  has been
terminated,  of the Aggregate Outstanding Credit Exposure) (determined as of the
date of any such request by the Agent) (i) for any amounts not reimbursed by the
Borrower for which the Agent is entitled to  reimbursement by the Borrower under
the Loan Documents,  (ii) to the extent not paid by the Borrower,  for any other
expenses incurred by the 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 Agent
in connection  with any dispute  between the Agent and any Lender or between two
or more of the  Lenders) and (iii) to the extent not paid by the  Borrower,  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 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
Agent in connection with any dispute between the 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 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 Agent, (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 and (iii) the Agent shall reimburse the Lenders for
any amounts the Lenders  have paid to the extent such  amounts are  subsequently
recovered from the Borrower.  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 Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Unmatured  Default  hereunder  unless
the 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 Agent receives such
a notice, the Agent shall give prompt notice thereof to the Lenders.

     10.10.  Rights as a Lender.  In the event the Agent is a Lender,  the Agent
shall  have the same  rights  and  powers  hereunder  and under  any other  Loan
Document with respect to its Commitment and its Credit  Extensions as any Lender
and may exercise the same as though it were not the Agent, and the term "Lender"
or "Lenders"  shall, at any time when the Agent is a Lender,  unless the context
otherwise indicates, include the Agent in its individual capacity. The

                                       53




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 Agent,  any 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 Agent,  any  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 Agent. The 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  Agent or, if no successor  Agent has been
appointed,  forty-five  days  after  the  retiring  Agent  gives  notice  of its
intention to resign.  The Agent may be removed at any time with or without cause
by written notice received by the Agent from the Required Lenders,  such removal
to be effective on the date  specified  by the Required  Lenders.  Upon any such
resignation or removal,  the Required Lenders,  with the consent of the Borrower
(which consent shall not be unreasonably withheld or delayed; provided that such
consent shall not be required in the event and continuation of a Default), shall
have the  right to  appoint,  on  behalf  of the  Borrower  and the  Lenders,  a
successor  Agent.  If no  successor  Agent shall have been so  appointed  by the
Required  Lenders or consented to by the Borrower  within  thirty days after the
resigning  Agent's giving notice of its intention to resign,  then the resigning
Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent.
Notwithstanding  the  previous  sentence,  the Agent may at any time without the
consent of the Borrower or any Lender,  appoint any of its Affiliates which is a
commercial  bank as a successor  Agent  hereunder.  If the Agent has resigned or
been removed and no successor Agent has been appointed,  the Lenders may perform
all the duties of the 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  Agent shall be
deemed to be appointed  hereunder  until such  successor  Agent has accepted the
appointment.  Any such successor Agent shall be a commercial bank having capital
and  retained  earnings of at least  $100,000,000.  Upon the  acceptance  of any
appointment as Agent hereunder by a successor Agent,  such successor Agent shall
thereupon succeed to and become vested with all the rights,  powers,  privileges
and duties of the  resigning or removed  Agent.  Upon the  effectiveness  of the
resignation  or removal of the Agent,  the  resigning or removed  Agent shall be
discharged  from  its  duties  and  obligations  hereunder  and  under  the Loan
Documents.  After the  effectiveness  of the resignation or removal of an Agent,
the  provisions  of this  Article X shall  continue in effect for the benefit of
such Agent in respect of any actions taken or omitted to be taken by it while it
was acting as the Agent  hereunder  and under the other Loan  Documents.  In the
event that there is a successor to the Agent by merger, or the 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 Agent.


                                       54




     10.13. Agent and Arranger Fees. The Borrower agrees to pay to the Agent and
each  Arranger,  for  their  respective  accounts,  the  fees  agreed  to by the
Borrower,  the Agent and the Arrangers pursuant to that certain letter agreement
dated June 12,  2003,  or as  otherwise  agreed from time to time.  The Borrower
further agrees to pay to the Agent and J.P. Morgan Securities Inc., as Arranger,
for their respective  accounts,  the fees agreed to by the Borrower  pursuant to
that certain engagement letter dated August 17, 2004.

     10.14.  Delegation to  Affiliates.  The Borrower and the Lenders agree that
the Agent may  delegate  any of its duties  under this  Agreement  to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees)  which performs duties in connection with this Agreement shall be
entitled  to  the  same  benefits  of  the  indemnification,  waiver  and  other
protective provisions to which the Agent is entitled under Articles IX and X.

     10.15. Syndication Agent and Documentation Agents. The Lender identified in
this  Agreement as the  "Syndication  Agent" and the Lenders  identified in this
Agreement as the "Documentation Agents" shall have no right, power,  obligation,
liability,  responsibility  or  duty  under  this  Agreement  other  than  those
applicable to all Lenders as such. Without limiting the foregoing,  such Lenders
shall  not have or be  deemed to have a  fiduciary  relationship  with any other
Lender. Each Lender hereby makes the same  acknowledgements with respect to such
Lenders as it makes with respect to the Agent in Section 10.11.

                                   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
(including  the  Swingline  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  Revolving  Credit  Exposure  (other than  payments
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 participation in the Aggregate  Revolving Credit Exposure held by the
other  Lenders so that after such  purchase  each  Lender will hold its Pro Rata
Share of the Aggregate  Revolving  Credit  Exposure.  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 of the
Aggregate  Revolving Credit  Exposure.  In case any such payment is disturbed by
legal process, or otherwise, appropriate further adjustments shall be made.

                                       55




                                  ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

     12.1. Successors and Assigns; Designated Lenders.

          12.1.1  Successors  and Assigns.  The terms and provisions of the Loan
     Documents  shall be binding upon and inure to the benefit of the  Borrower,
     the Agent and the  Lenders  and their  respective  successors  and  assigns
     permitted hereby,  except that (i) the Borrower shall not have the right to
     assign its rights or obligations under the Loan Documents without the prior
     written  consent of each Lender,  (ii) any assignment by any Lender must be
     made  in  compliance   with  Section  12.3,   and  (iii)  any  transfer  by
     Participants  must be made in compliance  with Section 12.2.  Any attempted
     assignment  or  transfer  by any  party  not made in  compliance  with this
     Section 12.1 shall be null and void,  unless such  attempted  assignment or
     transfer is treated as a  participation  in accordance with Section 12.3.2.
     The parties to this Agreement  acknowledge that clause (ii) of this Section
     12.1  relates only to absolute  assignments  and this Section 12.1 does not
     prohibit  assignments  creating  security  interests,   including,  without
     limitation,  (x) 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,  (y) in the case of a Lender which is a Fund,  any pledge or
     assignment of all or any portion of its rights under this Agreement and any
     Note to its trustee in support of its obligations to its trustee or (z) any
     pledge or  assignment  by any  Lender of all or any  portion  of its rights
     under  this  Agreement  and any  Note to  direct  or  indirect  contractual
     counterparties in swap agreements relating to the Loans; provided, however,
     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 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, however, that the 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.

          12.1.2 Designated Lenders.

     (i)  Subject to the terms and conditions set forth in this Section  12.1.2,
          any  Lender  may from  time to time  elect to  designate  an  Eligible
          Designee  to  provide  all or any part of the Loans to be made by such
          Lender pursuant to this Agreement; provided that the designation of an
          Eligible  Designee by any Lender for purposes of this  Section  12.1.2
          shall be subject to the approval of the Agent (which consent shall not
          be  unreasonably  withheld  or  delayed).  Upon the  execution  by the
          parties

                                       56



          to each such  designation  of an  agreement  in the form of  Exhibit F
          hereto (a "Designation  Agreement") and the acceptance  thereof by the
          Agent,  the Eligible  Designee  shall  become a Designated  Lender for
          purposes of this Agreement.  The Designating  Lender shall  thereafter
          have the right to permit the  Designated  Lender to  provide  all or a
          portion of the Loans to be made by the Designating  Lender pursuant to
          the terms of this  Agreement  and the  making of the Loans or  portion
          thereof shall satisfy the obligations of the Designating Lender to the
          same extent, and as if, such Loan was made by the Designating  Lender.
          As to any Loan made by it, each  Designated  Lender shall have all the
          rights a Lender  making such Loan would have under this  Agreement and
          otherwise;  provided,  (x) that all voting rights under this Agreement
          shall  be  exercised  solely  by  the  Designating  Lender,  (y)  each
          Designating  Lender  shall  remain  solely  responsible  to the  other
          parties hereto for its obligations under this Agreement, including the
          obligations  of a Lender in respect  of Loans  made by its  Designated
          Lender and (z) no Designated Lender shall be entitled to reimbursement
          under  Article III hereof for any amount which would exceed the amount
          that would have been  payable by the Borrower to the Lender from which
          the Designated Lender obtained any interests hereunder.  No additional
          Notes shall be required with respect to Loans provided by a Designated
          Lender;  provided,  however, to the extent any Designated Lender shall
          advance  funds,  the  Designating  Lender  shall be deemed to hold the
          Notes in its possession as an agent for such Designated  Lender to the
          extent of the Loan funded by such Designated Lender.  Such Designating
          Lender shall act as administrative agent for its Designated Lender and
          give and receive notices and  communications  hereunder.  Any payments
          for  the  account  of any  Designated  Lender  shall  be  paid  to its
          Designating Lender as administrative  agent for such Designated Lender
          and neither the  Borrower nor the Agent shall be  responsible  for any
          Designating  Lender's application of such payments.  In addition,  any
          Designated  Lender may (1) with  notice to, but without the consent of
          the Borrower or the Agent,  assign all or portions of its interests in
          any Loans to its  Designating  Lender or to any financial  institution
          consented to by the Agent providing liquidity and/or credit facilities
          to or for the  account of such  Designated  Lender and (2)  subject to
          advising  any such  Person that such  information  is to be treated as
          confidential   in  accordance   with  Section  9.11,   disclose  on  a
          confidential basis any non-public information relating to its Loans to
          any  rating  agency,  commercial  paper  dealer  or  provider  of  any
          guarantee,   surety  or  credit  or  liquidity   enhancement  to  such
          Designated Lender.

     (ii) Each party to this Agreement hereby agrees that it shall not institute
          against,  or  join  any  other  Person  in  instituting  against,  any
          Designated   Lender  any  bankruptcy,   reorganization,   arrangement,
          insolvency or liquidation  proceeding or other  proceedings  under any
          federal  or state  bankruptcy  or  similar  law for one year and a day
          after the payment in full of all  outstanding  senior  indebtedness of
          any Designated  Lender;  provided that the Designating Lender for each
          Designated  Lender hereby agrees to indemnify,  save and hold harmless
          each other party hereto for any loss, cost, damage and expense arising
          out of its  inability to institute  any such  proceeding  against such
          Designated  Lender.  This Section 12.1.2 shall survive the termination
          of this Agreement.


                                       57



     12.2. Participations.

          12.2.1 Permitted Participants; Effect. Any Lender may at any time sell
     to one or more  banks  or  other  entities  ("Participants")  participating
     interests in any Outstanding  Credit Exposure of such Lender, any Note held
     by such Lender, any Commitment of such Lender or any other interest of such
     Lender under the 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 Outstanding  Credit
     Exposure  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  shall be  determined  as if such Lender had not sold
     such participating interests, and the Borrower and the Agent shall continue
     to deal  solely  and  directly  with such  Lender in  connection  with such
     Lender's rights and obligations under 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 Credit Extension
     or Commitment in which such Participant has an interest which would require
     consent of all of the Lenders pursuant to the terms of Section 8.2.

          12.2.3 Benefit of Certain  Provisions.  The Borrower  agrees that each
     Participant shall be deemed to have the right of setoff provided in Section
     11.1 in respect of its  participating  interest in amounts  owing under the
     Loan  Documents  to the same  extent as if the amount of its  participating
     interest  were owing  directly to it as a Lender under the Loan  Documents,
     provided  that each  Lender  shall  retain the right of setoff  provided in
     Section 11.1 with respect to the amount of participating  interests sold to
     each  Participant.  The Lenders agree to share with each  Participant,  and
     each  Participant,  by exercising  the right of setoff  provided in Section
     11.1, agrees to share with each Lender, any amount received pursuant to the
     exercise of its right of setoff,  such  amounts to be shared in  accordance
     with  Section  11.2 as if each  Participant  were a  Lender.  The  Borrower
     further agrees that each  Participant  shall be entitled to the benefits of
     Sections  3.1,  3.2,  3.4 and 3.5 to the same extent as if it were a Lender
     and had  acquired  its  interest by  assignment  pursuant to Section  12.3,
     provided  that (i) a  Participant  shall not be  entitled  to  receive  any
     greater  payment under Section 3.1, 3.2 or 3.5 than the Lender who sold the
     participating  interest  to such  Participant  would have  received  had it
     retained  such  interest  for  its own  account,  unless  the  sale of such
     interest to such  Participant is made with the prior written consent of the
     Borrower,  and (ii) any Participant not incorporated  under the laws of the
     United  States of America or any State  thereof  agrees to comply  with the
     provisions of Section 3.5 to the same extent as if it were a Lender.

     12.3. Assignments.

          12.3.1 Permitted Assignments. Any Lender may at any time assign to one
     or more  banks  or  other  entities  ("Purchasers")  all or any part of its
     rights and obligations  under the Loan Documents.  Such assignment shall be
     evidenced by an agreement

                                       58



     substantially  in the form of  Exhibit  C or in such  other  form as may be
     agreed to by the  parties  thereto  (each such  agreement,  an  "Assignment
     Agreement").  Each such assignment with respect to a Purchaser which is not
     a Lender or an Affiliate of a Lender or an Approved Fund shall either be in
     an amount equal to the entire applicable  Commitment and Outstanding Credit
     Exposure of the  assigning  Lender or (unless  each of the Borrower and the
     Agent  otherwise  consents)  be  in  an  aggregate  amount  not  less  than
     $2,500,000.  The amount of the assignment  shall be based on the Commitment
     or,  if the  Commitments  have  been  terminated,  the  Outstanding  Credit
     Exposure  subject  to the  assignment,  determined  as of the  date of such
     assignment  or as of the "Trade  Date," if the "Trade Date" is specified in
     the  Assignment  Agreement.  Each  partial  assignment  shall be made as an
     assignment of a proportionate part of all the assigning Lender's rights and
     obligations under this Agreement, except that this sentence shall not apply
     to rights in respect of outstanding Competitive Loans.

          12.3.2  Consents.  The consent of the Borrower shall be required prior
     to an assignment  becoming  effective unless the Purchaser is a Lender,  an
     Affiliate of a Lender or an Approved Fund, provided that the consent of the
     Borrower  shall  not be  required  if (i) a  Default  has  occurred  and is
     continuing or (ii) if such  assignment  is in connection  with the physical
     settlement of any Lender's  obligations  to direct or indirect  contractual
     counterparties in swap agreements relating to the Loans; provided, that the
     assignment without the Borrower's consent pursuant to clause (ii) shall not
     increase the  Borrower's  liability  under  Section 3.5. The consent of the
     Agent (and, in the case of Swingline Loans, the Swingline  Lender) shall be
     required prior to an assignment  becoming effective unless the Purchaser is
     a  Lender,  an  Affiliate  of a Lender or an  Approved  Fund.  Any  consent
     required  under this Section 12.3.2 shall not be  unreasonably  withheld or
     delayed.

          12.3.3 Effect;  Effective  Date.  Upon (i) delivery to the Agent of an
     Assignment  Agreement,  together  with any  consents  required  by Sections
     12.3.1  and  12.3.2,  and (ii)  payment  of a $3,500  fee to the  Agent for
     processing  such  assignment  (unless  such fee is  waived  by the Agent or
     unless such assignment is made to such assigning Lender's Affiliate),  such
     assignment  shall become  effective on the effective date specified in such
     assignment.  The Assignment  Agreement shall contain a  representation  and
     warranty  by the  Purchaser  to the effect  that none of the funds,  money,
     assets or other  consideration  used to make the purchase and assumption of
     the  Commitment  and  Outstanding  Credit  Exposure  under  the  applicable
     Assignment  Agreement  constitutes "plan assets" as defined under ERISA and
     that the rights,  benefits 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,  benefits  and
     obligations of a Lender under the Loan Documents,  to the same extent as if
     it were an original  party  thereto,  and the  transferor  Lender  shall be
     released with respect to the Commitment and Outstanding Credit Exposure, if
     any,  assigned to such Purchaser  without any further  consent or action by
     the  Borrower,  the  Lenders  or the  Agent.  In the case of an  assignment
     covering all of the assigning  Lender's  rights,  benefits and  obligations
     under this Agreement,  such Lender shall cease to be a Lender hereunder but
     shall  continue to be entitled to the  benefits  of, and subject to,  those
     provisions  of this  Agreement and the other Loan  Documents  which

                                       59




     survive  payment of the  Obligations and termination of the Loan Documents.
     Any assignment or transfer by a Lender of rights or obligations  under this
     Agreement  that does not comply with this Section 12.3 shall be treated for
     purposes of this Agreement as a sale by such Lender of a  participation  in
     such rights and  obligations  in  accordance  with Section  12.2.  Upon the
     consummation  of any  assignment  to a Purchaser  pursuant to this  Section
     12.3.3,  the transferor  Lender,  the 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,  upon  cancellation  and
     surrender  to the  Borrower  of the Notes  (if any) held by the  transferor
     Lender, new Notes or, as appropriate,  replacement Notes are issued to such
     transferor  Lender,  if  applicable,  and new  Notes  or,  as  appropriate,
     replacement Notes, are issued to such Purchaser,  in each case in principal
     amounts  reflecting their  respective  Commitments (or, if such Commitments
     have been terminated,  their respective  Outstanding  Credit Exposure),  as
     adjusted pursuant to such assignment.

          12.3.4 Register. The Agent, acting solely for this purpose as an agent
     of the Borrower  (and the Borrower  hereby  designates  the Agent to act in
     such capacity),  shall maintain at one of its offices in New York, New York
     a copy of each  Assignment  and  Assumption  delivered to it and a register
     (the  "Register")  for the  recordation  of the names and  addresses of the
     Lenders,  and the Commitments of, and principal  amounts of and interest on
     the Loans owing to, each Lender  pursuant to the terms  hereof from time to
     time and whether  such Lender is an original  Lender or assignee of another
     Lender  pursuant to an assignment  under this Section 13.3.  The entries in
     the Register shall be conclusive,  absent  manifest error and the Borrower,
     the Agent and the Lenders  may treat each Person  whose name is recorded in
     the  Register  pursuant to the terms hereof as a Lender  hereunder  for all
     purposes of this  Agreement,  notwithstanding  notice to the contrary.  The
     Register  shall be available for inspection by the Borrower and any Lender,
     at any reasonable time and from time to time upon reasonable prior notice.

     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;  provided
that each  Transferee and prospective  Transferee  agrees to be bound by Section
9.11 of this Agreement.

     12.5.  Tax  Certifications.  If  any  interest  in  any  Loan  Document  is
transferred to any Transferee  which is not  incorporated  under the laws of 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).

     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 A2 or better or the Borrower's S&P Rating is A 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 A3 or
better or the Borrower's S&P Rating is A- 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 Baa1 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 Baa2 or better or the Borrower's S&P Rating is
BBB or better.

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

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



                                       1



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

     "Status"  means either Level I Status,  Level II Status,  Level III Status,
Level IV Status, Level V Status or Level VI Status.

     The  Applicable  Margin  and  Applicable  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 VI Status shall exist.

     If the Borrower is split-rated  and the ratings  differential is one level,
then each rating agency will be deemed to have a rating in the higher level.  If
the Borrower is split-rated and the ratings  differential is two levels or more,
then each  rating  agency  will be deemed to have a rating  one level  above the
lower rating,  unless either rating is below BB+ or unrated (in the case of S&P)
or below Ba1 or unrated  (in the case of  Moody's),  in which  case each  rating
agency will be deemed to have a rating in the lower level.

                                 FORM OF OPINION

                                 July ___, 2003


To the Lenders and
JPMorgan Chase Bank, as
      Administrative Agent
270 Park Avenue
New York, NY 10017

Dear Ladies and Gentlemen:

     I am the Vice President Regulatory Policy, General Counsel and Secretary of
Ameren Corporation, a Missouri corporation (the "Borrower"). I, or lawyers under
my  direction,  have acted as counsel for the  Borrower in  connection  with the
Three-Year  Revolving  Credit  Agreement dated as of July 17, 2003, (the "Credit
Agreement"),  among the Borrower, the lending institutions identified therein as
Lenders and JPMorgan Chase Bank, as Administrative  Agent.  Terms defined in the
Credit Agreement are used herein with the same meanings.

     In rendering the opinion expressed below, I, or lawyers under my direction,
have  examined  originals or copies,  certified or  otherwise  identified  to my
satisfaction,  of such  documents,  corporate  records,  certificates  of public
officials and other instruments and have conducted such other  investigations of
fact and law as I have  deemed  necessary  or  advisable  for  purposes  of this
opinion.

     In  making  the  examinations  described  above,  I  have  assumed  without
independent investigation the capacity of natural persons (other than the office
held by each  representative  of the  Borrower)  as  reflected  adjacent to such
individual's  signature  on  the  Credit  Agreement,   the  genuineness  of  all
signatures (other than those of representatives of the Borrower appearing on the
Credit  Agreement),  the  authenticity  of  all  documents  furnished  to  me as
originals,  the  conformity  to  originals of all  documents  furnished to me as
certified or photostatic  copies and the  authenticity  of the originals of such
documents.  In addition,  I have assumed without independent  investigation that
(i) the Credit Agreement has been duly authorized, executed and delivered by the
Lenders  and  the  Agent,  and  constitutes  their  valid,  lawful  and  binding
obligation and agreement, and (ii) there is no separate agreement,  undertaking,
or course of  dealing  modifying,  varying  or  waiving  any of the terms of the
Credit  Agreement.  As to matters of fact not  independently  established  by me
relevant to the opinions set forth  herein,  I have relied  without  independent
investigation  on the  representations  contained in the Credit Agreement and in
certificates of public officials and responsible representatives of the Borrower
furnished  to me;  provided,  however,  that I advise  that in the  course of my
representation  of the  Borrower,  I obtained  no  information  that leads me to
believe that any such  representation  or certificate is untrue or misleading in
any material respect.

                                       1




Upon the basis of and subject to the foregoing, I am of the opinion that:

     Each of the Borrower and its Subsidiaries is a corporation, partnership (in
the case of Subsidiaries  only) 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 as presently conducted in each jurisdiction in
which its business is conducted.

     The  Borrower  has the power and  authority  and legal right to execute and
deliver  the Loan  Documents  and to perform  its  obligations  thereunder.  The
execution and delivery by the Borrower of the Loan Documents and the performance
of its obligations  thereunder have been duly authorized by proper  proceedings,
and the Loan Documents to which the Borrower is a party constitute legal,  valid
and binding  obligations  of the  Borrower  enforceable  against the Borrower in
accordance  with their  terms,  except as  enforceability  may be limited by (i)
bankruptcy,  insolvency, fraudulent conveyance,  reorganization, or similar laws
relating to or affecting the enforcement of creditors'  rights  generally;  (ii)
general equitable principles (whether considered in a proceeding in equity or at
law); and (iii) requirements of reasonableness, good faith and fair dealing.

     Neither the execution  and delivery by the Borrower of the Loan  Documents,
nor the consummation of the transactions  therein  contemplated,  nor compliance
with the provisions thereof will 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, partnership agreement, certificate of partnership,
articles or  certificate of  organization,  by-laws,  or operating  agreement 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  under,  or 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  such  indenture,
instrument or agreement.  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 Credit  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.

     Except for the  Disclosed  Matters,  there is no  litigation,  arbitration,
governmental investigation, proceeding or inquiry currently existing, or, to the
best of my  knowledge  after due  inquiry,  pending  or  threatened  against  or
affecting  the  Borrower  of any  of  its  Subsidiaries,  which,  if  determined
adversely to the Borrower or to its  Subsidiaries,  could reasonably be expected
to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the
making  of any  Loans  or would  adversely  effect  the  legality,  validity  or

                                       2



enforceability  of the Loan  Documents or the ability of the Borrower to perform
the transactions contemplated therein.

     Neither the Borrower nor any  Subsidiary  is an  "investment  company" or a
company  "controlled"  by an  "investment  company,"  within the  meaning of the
Investment Company Act of 1940, as amended.

     The Borrower is a "holding  company," as such term is defined in the Public
Utility  Holding  Company Act of 1935, as amended (the "Holding  Company  Act").
Pursuant to the Holding  Company Act,  the  Securities  and Exchange  Commission
("SEC")  has issued its order  authorizing  the  incurrence  by the  Borrower of
short-term debt in the aggregate  principal amount not exceeding  $1,500,000,000
outstanding at any one time,  subject to the condition,  among others,  that all
such  short-term  debt be issued on or before  September 30, 2004, and mature no
later  than 364 days  thereafter.  Such  order of the SEC is in full  force  and
effect.  Loans  contemplated by the Credit  Agreement are short-term debt within
the  meaning of the  aforesaid  order of the SEC.  In order for the  Borrower to
borrow money under the Credit  Agreement  after  September  30, 2004, or to have
outstanding  more than  $1,500,000,000  in principal  amount of short-term  debt
(including   amounts   incurred   under  the   Credit   Agreement),   additional
authorization  from  SEC  will  be  necessary.  No  other  federal  governmental
consents, approvals, authorizations,  registrations, declarations or filings are
required in connection with the extensions of credit under the Credit  Agreement
or the  performance  by  the  Borrower  of  its  obligations  under  the  Credit
Agreement.

     In a properly  presented case, a Missouri court or a federal court applying
Missouri  choice of law rules should give effect to the choice of law provisions
of the Credit  Agreement  and should  hold that the  Credit  Agreement  is to be
governed  by the laws of the State of New York rather than the laws of the State
of Missouri.  In rendering the foregoing  opinion,  I note that by its terms the
Credit  Agreement  expressly  selects  New  York  law as the law  governing  its
interpretation  and that the Credit  Agreement was delivered to the Agent in New
York.  The choice of law  provisions  of the Credit  Agreement  are not voidable
under the laws of the State of Missouri.  Notwithstanding the foregoing, even if
a Missouri  court or a federal  court holds that the Credit  Agreement  is to be
governed by the laws of the State of Missouri,  the Credit Agreement constitutes
a legal,  valid and binding  obligation of Borrower  thereto,  enforceable under
Missouri law  (including  usury  provisions)  against the Borrower in accordance
with its terms.

     I express no opinion as to the compliance or  noncompliance,  or the effect
of the compliance or  noncompliance,  of any addressee with any state or federal
laws or  regulations  applicable to it by reason of its status as or affiliation
with a federally insured depository institution.

     I am a member of the Bar of the State of Missouri and the foregoing opinion
is  limited to the laws of the State of  Missouri  and the  Federal  laws of the
United  States of America.  I note that the Credit  Agreement is governed by the
laws of the State of New York and,  for  purposes  of the opinion  expressed  in
paragraph 2 above,  I have assumed that the laws of the State of New York do not
differ from the laws of the State of


                                       3



Missouri in any manner that would render such opinion incorrect. This opinion is
rendered solely to you in connection with the above matter. This opinion may not
be relied upon by you for any other  purpose or relied upon by any other  Person
(other than your  successors  and assigns as Lenders)  without my prior  written
consent.  Notwithstanding  anything in this opinion letter to the contrary,  you
may  disclose  this  opinion (i) to  prospective  successors  and assigns of the
addressees hereof,  (ii) to regulatory  authorities having jurisdiction over any
of the addressees hereof or their successors and assigns,  and (iii) pursuant to
valid legal  process,  in each case  without my prior  consent.  This opinion is
delivered as of the date hereof and I undertake no, and disclaim any, obligation
to advise you of any  change in matters of law or fact set forth  herein or upon
which this opinion is based.

                                          Very truly yours,



                                       4
