as of the then most recent valuation date for such Plan, but only to the extent
that such excess represents a potential liability of a member of the Controlled

      "U.S. Dollars" and "$" each means the lawful currency of the United States
of America.

      "Voting Stock" of any Person means capital stock of any class or classes

      Section 1.2 Interpretation. The foregoing definitions shall be equally
applicable to both the singular and plural forms of the terms defined. All
references to times of day in this Agreement shall be references to Chicago,
Illinois time unless otherwise specifically provided. Where the character or

inconsistent with the specific provisions of this Agreement.

      SECTION 2. THE REVOLVING CREDIT.

      Section 2.1 The Loan Commitment. Subject to the terms and conditions
hereof, each Bank, by its acceptance hereof, severally agrees to make a loan or
loans (individually a "Loan" and collectively "Loans") to the Borrower from time
to time on a revolving basis in an aggregate outstanding amount up to the amount
of its revolving credit commitment set forth on the applicable signature page
hereof (such amount, as increased or reduced pursuant to Section 2.12 or changed
as a result of one or more assignments under Section 11.12, its "Revolving
Credit Commitment" and, cumulatively for all the Banks, the "Revolving Credit
Commitments") before the Termination Date, provided that the sum of the
aggregate amount of Loans at any time outstanding shall not exceed the Revolving
Credit Commitments in effect at such time. Each Borrowing of Loans shall be made
ratably from the Banks in proportion to their respective Percentages. As
provided in Section 2.5(a) hereof, the Borrower may elect that each Borrowing of
Loans be either Base Rate Loans or LIBOR Loans. Loans may be repaid and the
principal amount thereof reborrowed before the Termination Date, subject to all
the terms and conditions hereof. The initial amount of Revolving Credit
Commitments under this Agreement equals $200,000,000.

      Section 2.2 [Reserved].

      Section 2.3 Applicable Interest Rates. (a) Base Rate Loans. Each Base Rate
Loan made or maintained by a Bank shall bear interest during each Interest
Period it is outstanding (computed (x) at all times the Base Rate is based on
the rate described in clause (i) of the definition thereof, on the basis of a
year of 365 or 366 days, as applicable, and actual days elapsed or (y) at all
times the Base Rate is based on the rate described in clause (ii) of the
definition thereof, on the basis of a year of 360 days and actual days elapsed)
on the unpaid principal amount thereof from the date such Loan is advanced,
continued or created by

                                        7


conversion from a LIBOR Loan until maturity (whether by acceleration or
otherwise) at a rate per annum equal to the sum of the Applicable Margin plus
the Base Rate from time to time in effect, payable on the last day of its
Interest Period and at maturity (whether by acceleration or otherwise).

      "Base Rate" means for any day the greater of:

            i the rate of interest announced by ABN AMRO Bank N.V. from time to
      time as its prime rate, or equivalent, for U.S. Dollar loans as in effect
      on such day, with any change in the Base Rate resulting from a change in
      said prime rate to be effective as of the date of the relevant change in
      said prime rate; and

            ii the sum of (x) the rate determined by the Agent to be the
      prevailing rate per annum (rounded upwards, if necessary, to the nearest
      one hundred-thousandth of a percentage point) at approximately 10:00 a.m.
      (Chicago time) (or as soon thereafter as is practicable) on such day (or,
      if such day is not a Business Day, on the immediately preceding Business
      Day) for the purchase at face value of overnight Federal funds in an
      amount comparable to the principal amount owed to ABN AMRO Bank N.V. for
      which such rate is being determined, plus (y) one-half of one percent
      (0.50%).

      (b) LIBOR Loans. Each LIBOR Loan made or maintained by a Bank shall bear
interest during each Interest Period it is outstanding (computed on the basis of
a year of 360 days and actual days elapsed) on the unpaid principal amount
thereof from the date such Loan is advanced, continued, or created by conversion
from a Base Rate Loan until maturity (whether by acceleration or otherwise) at a
rate per annum equal to the sum of the Applicable Margin plus the LIBOR
applicable for such Interest Period, payable on the last day of the Interest
Period and at maturity (whether by acceleration or otherwise), and, if the
applicable Interest Period is longer than three months, on each day occurring
every three months after the commencement of such Interest Period.

      "LIBOR" means, for an Interest Period for a Borrowing of LIBOR Loans, (a)
the LIBOR Index Rate for such Interest Period, if such rate is available, and
(b) if the LIBOR Index Rate cannot be determined, the arithmetic average of the
rates of interest per annum (rounded upwards, if necessary, to the nearest
one-sixteenth of one percent) at which deposits in U.S. Dollars in immediately
available funds are offered to each Reference Bank at 11:00 a.m. (London,
England time) two (2) Business Days before the beginning of such Interest Period
by major banks in the interbank LIBOR market for delivery on the first day of
and for a Period equal to such Interest Period in an amount equal or comparable
to the principal amount of the LIBOR Loan scheduled to be made by such Reference
Bank as part of such Borrowing.

      "LIBOR Index Rate" means, for any Interest Period, the rate per annum
(rounded upwards, if necessary, to the next higher one-sixteenth of one percent)
for deposits in U.S. Dollars, for delivery on the first day of and for a period
equal to such Interest Period in an amount equal or comparable to the principal
amount of the LIBOR Loan scheduled to be made by ABN AMRO Bank N.V. as part of
such Borrowing, which appears on the Applicable Telerate Page, as appropriate
for such currency, as of 11:00 a.m. (London, England time) on the day two (2)
Business Days before the commencement of such Interest Period.

                                        8


      "Applicable Telerate Page" means the display page designated as "Page
3750" on the Telerate Service (or such other page as may replace such page, as
appropriate, on that service or such other service as may be nominated by the
British Bankers' Association as the information vendor for the purpose of
displaying British Bankers' Association Interest Settlement Rates for deposits
in U.S. Dollars).

      "LIBOR Reserve Percentage" means for any Borrowing of LIBOR Loans from any
Bank, the daily average for the applicable Interest Period of the actual
effective rate, expressed as a decimal, at which reserves (including, without
limitation, any supplemental, marginal and emergency reserves) are maintained by
such Bank during such Interest Period pursuant to Regulation D of the Board of
Governors of the Federal Reserve System (or any successor) on "LIBOR
liabilities", as defined in such Board's Regulation D (or in respect of any
other category of liabilities that includes deposits by reference to which the
interest rate on LIBOR Loans is determined or any category of extensions of
credit or other assets that include loans by non-United States offices of any
Bank to United States residents), subject to any amendments of such reserve
requirement by such Board or its successor, taking into account any transitional
adjustments thereto. For purposes of this definition, the LIBOR Loans shall be
deemed to be "LIBOR liabilities" as defined in Regulation D without benefit or
credit for any prorations, exemptions or offsets under Regulation D.

      (c) Rate Determinations. The Agent shall determine each interest rate
applicable to Obligations and the amount of all Obligations, and a determination
thereof by the Agent shall be conclusive and binding except in the case of
manifest error.

      Section 2.4 Minimum Borrowing Amounts. Each Borrowing of Base Rate Loans
shall be in an amount not less than $1,000,000 and in integral multiples of
$500,000. Each Borrowing of LIBOR Loans shall be in an amount not less than
$2,000,000 and in integral multiples of $1,000,000.

      Section 2.5 Manner of Borrowing Loans and Designating Interest Rates
Applicable to Loans. (a) Notice to the Agent. The Borrower shall give notice to
the Agent by no later than 10:00 a.m. (Chicago time) (i) at least three (3)
Business Days before the date on which the Borrower requests the Banks to
advance a Borrowing of LIBOR Loans and (ii) at least one (1) Business Day before
the date on which the Borrower requests the Banks to advance a Borrowing of Base
Rate Loans. The Loans included in each Borrowing shall bear interest initially
at the type of rate specified in such notice of a new Borrowing. Thereafter, the
Borrower may from time to time elect to change or continue the type of interest
rate borne by each Borrowing or, subject to Section 2.4's minimum amount
requirement for each outstanding Borrowing, a portion thereof, as follows: (i)
if such Borrowing is of LIBOR Loans, on the last day of the Interest Period
applicable thereto, the Borrower may continue part or all of such Borrowing as
LIBOR Loans for an Interest Period or Interest Periods specified by the Borrower
or convert part or all of such Borrowing into Base Rate Loans, (ii) if such
Borrowing is of Base Rate Loans, on any Business Day, the Borrower may convert
all or part of such Borrowing into LIBOR Loans for an Interest Period or
Interest Periods specified by the Borrower. The Borrower shall give all such
notices requesting, the advance, continuation, or conversion of a Borrowing to
the Agent by telephone or facsimile (which notice shall be irrevocable once
given and, if by telephone, shall be promptly confirmed in writing). Notices of
the continuation of a Borrowing of LIBOR Loans

                                        9


for an additional Interest Period or of the conversion of part or all of a
Borrowing of LIBOR Loans into Base Rate Loans or of Base Rate Loans into LIBOR
Loans must be given by no later than 10:00 a.m. (Chicago time) at least three
(3) Business Days before the date of the requested continuation or conversion.
All such notices concerning the advance, continuation, or conversion of a
Borrowing shall specify the date of the requested advance, continuation or
conversion of a Borrowing (which shall be a Business Day), the amount of the
requested Borrowing to be advanced, continued, or converted, the type of Loans
to comprise such new, continued or converted Borrowing and, if such Borrowing is
to be comprised of LIBOR Loans, the Interest Period applicable thereto. The
Borrower agrees that the Agent may rely on any such telephonic or facsimile
notice given by any person it in good faith believes is an Authorized
Representative without the necessity of independent investigation, and in the
event any such notice by telephone conflicts with any written confirmation, such
telephonic notice shall govern if the Agent has acted in reliance thereon. There
may be no more than fifteen different Interest Periods in effect at any one
time, provided that for purposes of determining the number of Interest Periods
in effect at any one time, all Base Rate Loans shall be deemed to have one and
the same Interest Period.

      (b) Notice to the Banks. The Agent shall give prompt telephonic or
facsimile notice to each Bank of any notice from the Borrower received pursuant
to Section 2.5(a) above. The Agent shall give notice to the Borrower and each
Bank by like means of the interest rate applicable to each Borrowing of LIBOR
Loans.

      (c) Borrower's Failure to Notify. Any outstanding Borrowing of Base Rate
Loans shall, subject to Section 6.2 hereof, automatically be continued for an
additional Interest Period on the last day of its then current Interest Period
unless the Borrower has notified the Agent within the period required by Section
2.5(a) that it intends to convert such Borrowing into a Borrowing of LIBOR Loans
or notifies the Agent within the period required by Section 2.8(a) that it
intends to prepay such Borrowing. If the Borrower fails to give notice pursuant
to Section 2.5(a) above of the continuation or conversion of any outstanding
principal amount of a Borrowing of LIBOR Loans before the last day of its then
current Interest Period within the period required by Section 2.5(a) and has not
notified the Agent within the period required by Section 2.8(a) that it intends
to prepay such Borrowing, such Borrowing shall automatically be converted into a
Borrowing of Base Rate Loans, subject to Section 6.2 hereof. The Agent shall
promptly notify the Banks of the Borrower's failure to so give a notice under
Section 2.5(a).

      (d) Disbursement of Loans. Not later than 11:00 a.m. (Chicago time) on the
date of any requested advance of a new Borrowing of LIBOR Loans, and not later
than 12:00 noon (Chicago time) on the date of any requested advance of a new
Borrowing of Base Rate Loans, subject to Section 6 hereof, each Bank shall make
available its Loan comprising part of such Borrowing in funds immediately
available at the principal office of the Agent in Chicago, Illinois. The Agent
shall make available to the Borrower Loans at the Agent's principal office in
Chicago, Illinois or such other office as the Agent has previously agreed in
writing to with the Borrower, in each case in the type of funds received by the
Agent from the Banks.

      (e) Agent Reliance on Bank Funding. Unless the Agent shall have been
notified by a Bank before the date on which such Bank is scheduled to make
payment to the Agent of the proceeds of a Loan (which notice shall be effective
upon receipt) that such Bank does not intend to make such payment, the Agent may
assume that such Bank has made such payment when due

                                       10


and the Agent may in reliance upon such assumption (but shall not be required
to) make available to the Borrower the proceeds of the Loan to be made by such
Bank and, if any Bank has not in fact made such payment to the Agent, such Bank
shall, on demand, pay to the Agent the amount made available to the Borrower
attributable to such Bank together with interest thereon in respect of each day
during the period commencing on the date such amount was made available to the
Borrower and ending on (but excluding) the date such Bank pays such amount to
the Agent at a rate per annum equal to the Federal Funds Rate. If such amount is
not received from such Bank by the Agent immediately upon demand, the Borrower
will, on demand, repay to the Agent the proceeds of the Loan attributable to
such Bank with interest thereon at a rate per annum equal to the interest rate
applicable to the relevant Loan, provided that such a repayment by the Borrower
shall not be subject to Section 2.11 hereof.

      Section 2.6 Interest Periods. As provided in Section 2.5(a) hereof, at the
time of each request to advance, continue, or create by conversion a Borrowing
of LIBOR Loans, the Borrower shall select an Interest Period applicable to such
Loans from among the available options. The term "Interest Period" means the
period commencing on the date a Borrowing of Loans is advanced, continued, or
created by conversion and ending: (a) in the case of Base Rate Loans, on the
last Business Day of the calendar quarter in which such Borrowing is advanced,
continued, or created by conversion (or on the last day of the following
calendar quarter if such Loan is advanced, continued or created by conversion on
the last Business Day of a calendar quarter), and (b) in the case of LIBOR
Loans, 1, 2, 3, or 6 months thereafter; provided, however, that:

      (a) any Interest Period for a Borrowing of Base Rate Loans that otherwise
would end after the Termination Date shall end on the Termination Date;

      (b) for any Borrowing of LIBOR Loans, the Borrower may not select an
Interest Period that extends beyond the Termination Date;

      (c) whenever the last day of any Interest Period would otherwise be a day
that is not a Business Day, the last day of such Interest Period shall be
extended to the next succeeding Business Day, provided that, if such extension
would cause the last day of an Interest Period for a Borrowing of LIBOR Loans to
occur in the following calendar month, the last day of such Interest Period
shall be the immediately preceding Business Day; and

      (d) for purposes of determining an Interest Period for a Borrowing of
LIBOR Loans, a month means a period starting on one day in a calendar month and
ending on the numerically corresponding day in the next calendar month;
provided, however, that if there is no numerically corresponding day in the
month in which such an Interest Period is to end or if such an Interest Period
begins on the last Business Day of a calendar month, then such Interest Period
shall end on the last Business Day of the calendar month in which such Interest
Period is to end.

      Section 2.7 Maturity of Loans. Unless an earlier maturity is provided for
hereunder (whether by acceleration or otherwise), each Loan shall mature and
become due and payable by the Borrower on the Termination Date.

                                       11


      Section 2.8 Prepayments. (a) The Borrower may prepay without premium or
penalty and in whole or in part (but, if in part, then: (i) if such Borrowing is
of Base Rate Loans, in an amount not less than $5,000,000 and integral multiples
of $1,000,000 in excess thereof, (ii) if such Borrowing is of LIBOR Loans, in an
amount not less than $5,000,000 and integral multiples of $1,000,000 in excess
thereof and (iii) in an amount such that the minimum amount required for a
Borrowing pursuant to Section 2.4 hereof remains outstanding) any Borrowing of
LIBOR Loans upon three Business Days' prior notice to the Agent or, in the case
of a Borrowing of Base Rate Loans, notice delivered to the Agent no later than
10:00 a.m. (Chicago time) on the date of prepayment, such prepayment to be made
by the payment of the principal amount to be prepaid and accrued interest
thereon to the date fixed for prepayment. In the case of LIBOR Loans, any
amounts owing under Section 2.11 hereof as a result of such prepayment shall be
paid contemporaneously with such prepayment. The Agent will promptly advise each
Bank of any such prepayment notice it receives from the Borrower. Any amount
paid or prepaid before the Termination Date may, subject to the terms and
conditions of this Agreement, be borrowed, repaid and borrowed again.

      (b) At any time that the Borrower becomes aware, or should have become
aware (pursuant to Borrower's ordinary business practices) that the aggregate
amount of outstanding Loans shall at any time for any reason exceed the
Revolving Credit Commitments then in effect, the Borrower shall, immediately
notify the Agent of this determination. Within two (2) Business Days of the
delivery of the notice described in the preceding sentence, the Borrower shall,
without further notice or demand, pay the amount of such excess to the Agent for
the ratable benefit of the Banks as a prepayment of the Loans. Each such
prepayment shall be accompanied by a payment of all accrued and unpaid interest
on the Loans prepaid and shall be subject to Section 2.11.

      Section 2.9 Default Rate. If any payment of principal on any Loan or other
Obligation is not made when due (whether by acceleration or otherwise), such
Loan shall bear interest (computed on the basis of a year of 360 days and actual
days elapsed or, if based on the rate described in clause (i) of the definition
of Base Rate, on the basis of a year of 365 or 366 days, as applicable, and the
actual number of days elapsed) from the date such payment was due until paid in
full, payable on demand, at a rate per annum equal to:

      (a) for any Base Rate Loan or Obligation other than a LIBOR Loan, the sum
of two percent (2%) plus the Applicable Margin plus the Base Rate from time to
time in effect; and

      (b) for any LIBOR Loan, the sum of two percent (2%) plus the rate of
interest in effect thereon at the time of such default until the end of the
Interest Period applicable thereto and, thereafter, at a rate per annum equal to
the sum of two percent (2%) plus the Applicable Margin plus the Base Rate from
time to time in effect.

      Section 2.10 Evidence of Debt. (a) Each Bank shall maintain in accordance
with its usual practice an account or accounts evidencing the indebtedness of
the Borrower to such Bank resulting from each Loan owing to such Bank from time
to time, including the amounts of principal and interest payable and paid to
such Bank from time to time hereunder in respect of Loans. The Borrower agrees
that upon notice by any Bank to the Borrower (with a copy of such notice to the
Agent) to the effect that a Note is required or appropriate in order for such
Bank to

                                       12


evidence (whether for purposes of pledge, enforcement or otherwise) the Loans
owing to, or to be made by, such Bank under the Credit Documents, the Borrower
shall promptly execute and deliver to such Bank a promissory note in the form of
Exhibit A hereto (each such promissory note is hereinafter referred to as a
"Note" and collectively such promissory notes are referred to as the "Notes").

      (b) The Register maintained by the Agent pursuant to Section 11.12(c)
shall include a control account, and a subsidiary account for each Bank, in
which accounts (taken together) shall be recorded (i) the date and amount of
each Borrowing made hereunder, the type of Loan comprising such Borrowing and,
if appropriate, the Interest Period applicable thereto, (ii) the terms of each
Assignment and Acceptance delivered to and accepted by it, (iii) the amount of
any principal or interest due and payable or to become due and payable from the
Borrower to each Bank hereunder and (iv) the amount of any sum received by the
Agent from the Borrower hereunder and each Bank's share thereof.

      (c) Entries made in good faith by the Agent in the Register pursuant to
subsection (b) above, and by each Bank in its account or accounts pursuant to
subsection (a) above, shall be prima facie evidence of the amount of principal
and interest due and payable or to become due and payable from the Borrower to,
in the case of the Register, each Bank and, in the case of such account or
accounts, such Bank, under this Agreement, absent manifest error; provided,
however, that the failure of the Agent or such Bank to make an entry, or any
finding that an entry is incorrect, in the Register or such account or accounts
shall not limit or otherwise affect the obligations of the Borrower under this
Agreement.

      Section 2.11 Funding Indemnity. If any Bank shall incur any loss, cost or
expense (including, without limitation, any loss, cost or expense (excluding
loss of margin) incurred by reason of the liquidation or re-employment of
deposits or other funds acquired by such Bank to fund or maintain any LIBOR Loan
or the relending or reinvesting of such deposits or amounts paid or prepaid to
such Bank) as a result of:

      (a) any payment (whether by acceleration or otherwise), prepayment or
conversion of a LIBOR Loan on a date other than the last day of its Interest
Period,

      (b) any failure (because of a failure to meet the conditions of Section 6
or otherwise) by the Borrower to borrow or continue a LIBOR Loan, or to convert
a Base Rate Loan into a LIBOR Loan, on the date specified in a notice given
pursuant to Section 2.5(a) or established pursuant to Section 2.5(c) hereof,

      (c) any failure by the Borrower to make any payment of principal on any
LIBOR Loan when due (whether by acceleration or otherwise), or

      (d) any acceleration of the maturity of a LIBOR Loan as a result of the
occurrence of any Event of Default hereunder,

then, upon the demand of such Bank, the Borrower shall pay to such Bank such
amount as will reimburse such Bank for such loss, cost or expense. If any Bank
makes such a claim for compensation, it shall provide to the Borrower, with a
copy to the Agent, a certificate executed by an officer of such Bank setting
forth the amount of such loss, cost or expense in reasonable

                                       13


detail (including an explanation of the basis for and the computation of such
loss, cost or expense) and the amounts shown on such certificate if reasonably
calculated shall be conclusive absent manifest error.

      Section 2.12 Revolving Credit Commitment Terminations. The Borrower shall
have the right at any time and from time to time, upon five (5) Business Days'
prior written notice to the Agent, to terminate the Revolving Credit Commitments
without premium or penalty, in whole or in part, any partial termination to be
(i) in an amount not less than $5,000,000 and integral multiples of $1,000,000
in excess thereof, and (ii) allocated ratably among the Banks in proportion to
their respective Percentages, provided that the Revolving Credit Commitments may
not be reduced to an amount less than the sum of the amount of all Loans then
outstanding. The Agent shall give prompt notice to each Bank of any such
termination of Revolving Credit Commitments. Any termination of Revolving Credit
Commitments pursuant to this Section 2.12 may not be reinstated.

      Section 2.13 Regulation D Compensation. Each Bank may require the Borrower
to pay, contemporaneously with each payment of interest on the LIBOR Loans,
additional interest on the related LIBOR Loans of such Bank at a rate per annum
equal to the excess of (i)(A) the applicable LIBOR rate (or other base rate
determined pursuant to Section 2.9(b)) divided by (B) one minus the LIBOR
Reserve Percentage over (ii) the rate specified in clause (i)(A). Any
computation by a Bank of such additional interest shall be conclusive absent
manifest error. Any Bank wishing to require payment of such additional interest
(x) shall notify the Borrower and the Agent that it is subject to LIBOR reserves
under Regulation D of the Board of Governors of the Federal Reserve System (or
any successor regulation), in which case such additional interest on the LIBOR
Loans of such Bank shall be payable to such Bank at the place indicated in such
notice with respect to each Interest Period commencing at least five (5)
Business Days after the giving of such notice and (y) shall notify the Borrower
at least five (5) Business Days prior to each date on which interest is payable
on the LIBOR Loans of the amount then due under this Section.

      Section 2.14 Arbitrage Compensation. If at the time of the making of any
Loan hereunder, the interest rate payable hereunder in respect of such Loan is
less than the rate (as determined by the Agent in consultation with the
Borrower) at which funds of comparable term and amount are generally available
to the Borrower in the commercial paper market (the "CP Rate") (an "Arbitrage
Condition"), the Borrower agrees to pay to the Agent for the account of each
Bank arbitrage compensation on such Loan at a rate equal to the difference
between the effective interest rate payable hereunder (inclusive of all fees) in
respect of such Loan and the CP Rate as applied to such Loan. Such payments
shall continue, at the time and in the manner set forth for payments of interest
on such Loan, for as long as the Arbitrage Condition continues. Upon the
termination of the Arbitrage Condition for any reason (as determined by the
Agent in consultation with the Borrower), such payments shall no longer be due
with respect to such Loan, even if a future Arbitrage Condition were to occur
prior to repayment in full of such Loan.

      SECTION 3. FEES.

      Section 3.1 Fees.

                                       14


      (a) Commitment Fee. For the period from the Effective Date to and
including the Termination Date, Borrower shall pay to the Agent for the ratable
account of the Banks in accordance with their Percentages a commitment fee
accruing at a rate per annum equal to the Commitment Fee Rate on the average
daily amount of the unused Revolving Credit Commitments. Such commitment fee is
payable in arrears on September 30, 2004, on the last Business Day of each
calendar quarter thereafter and on the Termination Date, unless the Revolving
Credit Commitments are terminated in whole on an earlier date, in which event
the fee for the period to but not including the date of such termination shall
be paid in whole on the date of such termination.

      (b) Agent Fees. The Borrower shall pay to the Agent for the sole account
of the Agent the fees agreed to between the Agent and the Borrower in the Fee
Letter or as otherwise agreed in writing between them.

      (c) Fee Calculations. All fees payable under this Agreement shall be
payable in U.S. Dollars and shall be computed on the basis of a year of 360
days, for the actual number of days elapsed. All determinations of the amount of
fees owing hereunder (and the components thereof) shall be made by the Agent and
shall be conclusive absent manifest error.

      Section 3.2 Replacement of Banks. If any Bank requests compensation
pursuant to Section 9.3 or 11.1 hereof, or any Bank's obligations to make Loans
shall be suspended pursuant to Section 9.1 or 9.2 hereof, or any Bank becomes a
Defaulting Bank pursuant to Section 11.13 hereof (any such Bank requesting such
compensation, or whose obligations are so suspended, or that becomes and remains
a Defaulting Bank being herein called a "Subject Bank"), the Borrower, upon
three Business Days' notice, may require that such Subject Bank enter into an
agreement in form and substance satisfactory to the Borrower and the Agent which
transfers all of its right, title and interest under this Agreement and such
Subject Bank's Note to any bank or other financial institution (a "Proposed
Bank") identified by the Borrower that is satisfactory to the Agent (i) if such
Proposed Bank agrees to assume all of the obligations of such Subject Bank
hereunder, and to purchase all of such Subject Bank's Loans for a consideration
equal to the aggregate outstanding principal amount of such Subject Bank's
Loans, together with interest thereon to the date of such purchase, and
satisfactory arrangements are made for payment to such Subject Bank of all other
amounts payable hereunder to such Subject Bank on or prior to the date of such
transfer (including any fees accrued hereunder, any requested compensation
pursuant to Section 9.3 or 11.1 hereof and any amounts that would be payable
under Section 2.11 hereof as if all of such Subject Bank's Loans were being
prepaid in full on such date) and (ii) if such Subject Bank has requested
compensation pursuant to Section 9.3 or 11.1 hereof, such Proposed Bank's
aggregate requested compensation, if any, pursuant to said Section 9.3 or 11.1
with respect to such Subject Bank's Loans is lower than that of the Subject
Bank, and thereupon such Proposed Bank shall be a "Bank" for all purposes of
this Agreement.

      SECTION 4. PLACE AND APPLICATION OF PAYMENTS.

      Section 4.1 Place and Application of Payments. All payments of principal
of and interest on the Loans, and of all other amounts payable by the Borrower
under the Credit Documents, shall be made by the Borrower to the Agent by no

                                       15


pursuant to the payment instructions set forth on Part A of Schedule 4 hereof
(or such other location in the, United States as the Agent may designate to the
Borrower), in each case for the benefit of the Person or Persons entitled
thereto. Any payments received after such time shall be deemed to have been
received by the Agent on the next Business Day. All such payments shall be made
free and clear of, and without deduction for, any set-off, counterclaim, levy,
or any other deduction of any kind in U.S. Dollars, in immediately available
funds at the place of payment. The Agent will promptly thereafter cause to be

or applicable fees ratably to the Banks and like funds relating to the payment
of any other amount payable to any Person to such Person, in each case to be
applied in accordance with the terms of this Agreement.

      SECTION 5. REPRESENTATIONS AND WARRANTIES.

      The Borrower hereby represents and warrants to each Bank as to itself and,
where the following representations and warranties apply to Subsidiaries, as to
each of its Subsidiaries, as follows:

      Section 5.1 Corporate Organization and Authority. The Borrower is duly
organized and existing in good standing under the laws of the State of Illinois;
has all necessary corporate power to carry on its present business; and is duly
licensed or qualified and, in good standing in each jurisdiction in which the
failure to be so licensed, qualified or in good standing would have a Material
Adverse Effect.

      Section 5.2 Corporate Authority and Validity of Obligations. The Borrower
has full right and authority to enter into this Agreement and the other Credit
Documents to which it is a party, to make the borrowings herein provided for, to
issue its Notes in evidence thereof, and to perform all of its obligations under
the Credit Documents to which it is a party. Each Credit Document to which it is
a party has been duly authorized, executed and delivered by the Borrower and
constitutes valid and binding obligations of the Borrower enforceable in
accordance with its terms, except as such enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforceability of creditors' rights generally and by equitable principles of
general applicability (regardless of whether such enforceability is considered
in a proceeding in equity or at law). No Credit Document, nor the performance or
observance by the Borrower of any of the matters or things therein provided for,
contravenes any provision of law or any charter or by-law provision of the
Borrower or any material Contractual Obligation of or affecting the Borrower or
any of its Properties or results in or requires the creation or imposition of
any Lien on any of the Properties or revenues of the Borrower.

      Section 5.3 Financial Statements. All financial statements heretofore
delivered to the Banks showing historical performance of the Borrower for each
of the Borrower's fiscal years ending on or before September 30, 2003, have been
prepared in accordance with generally accepted accounting principles applied on
a basis consistent, except as otherwise noted therein, with that of the previous
fiscal year. Each of such financial statements fairly presents on a consolidated
basis the financial condition of the Borrower and its Subsidiaries as of the
dates thereof and the results of operations for the periods covered thereby. The
Borrower and its Subsidiaries have no material contingent liabilities other than
those disclosed in the financial

                                       16


statements or in comments or footnotes thereto, or in any report supplementary
thereto, most recently furnished to the Banks as of the time such representation
and warranty is made, including reports of the Borrower filed with the SEC from
time to time. Since June 30, 2004 through the Effective Date, there has been no
event or series of events which has resulted in a Material Adverse Effect.

      Section 5.4 Approvals. No authorization, approval, consent, license,
exemption, filing or registration with any court or governmental department,
agency or instrumentality, nor any approval or consent of the stockholders of
the Borrower or any Subsidiary or from any other Person, is necessary to the
valid execution, delivery or performance by the Borrower or any Subsidiary of
any Credit Document to which it is a party.

      Section 5.5 ERISA. With respect to each Plan, the Borrower and each other
member of the Controlled Group has fulfilled its obligations under the minimum
funding standards of and is in compliance in all material respects with the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and with
the Code to the extent applicable to it and has not incurred any liability to
the Pension Benefit Guaranty Corporation ("PBGC") or a Plan under Title IV of
ERISA other than a liability to the PBGC for premiums under Section 4007 of
ERISA. Neither the Borrower nor any Subsidiary has any contingent liabilities
for any post-retirement benefits under a Welfare Plan, other than liability for
continuation coverage described in Part 6 of Title I of ERISA.

      Section 5.6 Government Regulation. Neither the Borrower nor any Subsidiary
is an "investment company" within the meaning of the Investment Company Act of
1940, as amended.

      Section 5.7 Margin Stock; Proceeds. Neither the Borrower nor any
Subsidiary is engaged principally, or as one of its primary activities, in the
business of extending credit for the purpose of purchasing or carrying margin
stock ("margin stock" to have the same meaning herein as in Regulation U of the
Board of Governors of the Federal Reserve System). The Borrower will not use the
proceeds of any Loan in a manner that violates any provision of Regulation U or
X of the Board of Governors of the Federal Reserve System. The Borrower is not
subject to regulation under the Investment Company Act of 1940. In addition, the
Borrower is not an "investment company" registered or required to be registered
under the Investment Company Act of 1940. Proceeds of the Loans will only be
used to backstop commercial paper issued by the Borrower and for general
corporate purposes.

      Section 5.8 Full Disclosure. All information heretofore furnished by the
Borrower to the Agent or any Bank for purposes of or in connection with the
Credit Documents or any transaction contemplated thereby is, and all such
information hereafter furnished by the Borrower to the Agent or any Bank will
be, to the best of the Borrower's knowledge, after due inquiry, true and
accurate in all material respects and not misleading on the date as of which
such information is stated or certified.

      SECTION 6. CONDITIONS PRECEDENT.

                                       18

representation or warranty relates solely to an earlier date it need only remain
true as of such date; and

      (c) The Borrower shall be in full compliance with all of the terms and

      Section 7.1 Corporate Existence. Borrower shall preserve and maintain its
corporate existence

      Section 7.2 ERISA. The Borrower will, and will cause each of its
Subsidiaries to, promptly pay and discharge all obligations and liabilities
arising under ERISA of a character which if unpaid or unperformed might result
in the imposition of a Lien against any of its properties or assets and will
promptly notify the Agent of (i) the occurrence of any reportable event (as
defined in ERISA) affecting a Plan, other than any such event of which the PBGC
has waived notice by regulation, (ii) receipt of any notice from PBGC of its
intention to seek termination of any Plan or appointment of a trustee therefor,
(iii) its or any of its Subsidiaries' intention to terminate or withdraw from

result in the incurrence by the Borrower or any of its Subsidiaries of any

liability of the Borrower or any of its Subsidiaries under any post-retirement
Welfare Plan benefit. The Agent will promptly distribute to each Bank any notice

      national standing selected by the Borrower in accordance with GAAP with
      such accountants' opinion to the effect that the financial statements have
      been prepared in accordance with GAAP and present fairly in all material
      respects in accordance with GAAP the consolidated financial position of
      the Borrower and its Subsidiaries as of the

                                       19


      close of such fiscal year and the results of their operations and cash
      flows for the fiscal year then ended and that an examination of such
      accounts in connection with such financial statements has been made in

part" of the fixed assets of the Borrower if the net book value of such assets,
when added to the net book value of all other fixed assets sold, leased,
transferred or disposed of by the Borrower during the term of this Agreement

                                       20

ordinances and orders of any governmental or judicial authorities; provided,

regulation, ordinance or order if the failure to comply therewith could not
reasonably be expected to have a Material Adverse Effect.

default, such additional cure period not to exceed thirty (30) days;

the Borrower in an aggregate principal amount of $15,000,000 or more and such

prepayment, purchase or funding;

      (e) representation or warranty made herein or in any other Credit Document
by the Borrower, or in any statement or certificate furnished pursuant hereto or

contested in good faith in a manner that stays execution thereon; or

      (i) the Borrower or any other member of the Controlled Group shall fail to

$5,000,000 (collectively, a "Material Plan") shall be filed under Title IV of
ERISA by the Borrower or any other member of the Controlled Group, any plan
administrator or any combination of the foregoing; or the PBGC shall institute
proceedings under Title IV of ERISA to terminate or to cause a trustee to be
appointed to administer any Material Plan or a proceeding shall be instituted by

and all other obligations of the Banks hereunder (other than the obligations of
the Banks under section 11.21 hereof) on the date stated in such notice (which
may be the date thereof); and (b) declare the principal of and the accrued
interest on all outstanding Notes to be forthwith due and payable and thereupon
all outstanding Notes,

                                       22


including both principal and interest thereon, shall be and become immediately
due and payable together with all other amounts payable under the Credit
Documents without further demand, presentment, protest or notice of any kind.
The Agent, after giving notice to the Borrower pursuant to Section 8.1(c) or
this Section 8.2, shall also promptly send a copy of such notice to the other
Banks, but the failure to do so shall not impair or annul the effect of such
notice.

then all outstanding Notes shall immediately become due and payable together

Default or Event of Default by the Borrower hereunder or in connection with the
enforcement of any of the Credit Documents.

      SECTION 9. CHANGE IN CIRCUMSTANCES.

      Section 9.1 Change of Law. Notwithstanding any other provisions of this
Agreement or any Note, if at any time after the date hereof any change in
applicable law or regulation or in the interpretation thereof makes it unlawful
for any Bank to make or continue to maintain LIBOR Loans or to perform its
obligations as contemplated hereby, such Bank shall promptly give notice thereof
to the Borrower and such Bank's obligations to make or maintain LIBOR Loans
under this Agreement shall terminate until it is no longer unlawful for such
Bank to make or maintain LIBOR Loans. The Borrower shall prepay on demand the
outstanding principal amount of any such affected LIBOR Loans, together with all
interest accrued thereon at a rate per annum equal to the interest rate
applicable to such Loan; provided, however, subject to all of the terms and
conditions of this Agreement, the Borrower may then elect to borrow the
principal amount of the affected LIBOR Loans from such Bank by means of Base
Rate Loans from such Bank, which Base Rate Loans shall not be made ratably by
the Banks but only from such affected Bank.

      Section 9.2 Unavailability of Deposits or Inability to Ascertain, or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any Borrowing of LIBOR Loans:

      (a) the Agent determines that deposits in U.S. Dollars (in the applicable
amounts) are not being offered to major banks in the LIBOR interbank market for
such Interest Period, or that by reason of circumstances affecting the interbank
LIBOR market adequate and reasonable means do not exist for ascertaining the
applicable LIBOR, or

      (b) Banks having twenty five percent (25%) or more of the aggregate amount
of the Revolving Credit Commitments reasonably determine and so advise the Agent
that LIBOR as reasonably determined by the Agent will not adequately and fairly
reflect the cost to such Banks or Bank of funding their or its LIBOR Loans or
Loan for such Interest Period,

                                       23


then the Agent shall forthwith give notice thereof to the Borrower and the
Banks, whereupon until the Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Banks or
of the relevant Bank to make LIBOR Loans shall be suspended.

      Section 9.3 Increased Cost and Reduced Return. (a) If, on or after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Lending Office) with any request or directive (whether or not having the force
of law but, if not having the force of law, compliance with which is customary
in the relevant jurisdiction) of any such authority, central bank or comparable
agency:

            i shall subject any Bank (or its Lending Office) to any tax, duty or
      other charge with respect to its LIBOR Loans, its Notes, or shall change
      the basis of taxation of payments to any Bank (or its Lending Office) of
      the principal of or interest on its LIBOR Loans or any other amounts due
      under this Agreement in respect of its LIBOR Loans, or its obligation to
      make LIBOR Loans (except for changes in the rate of tax on the overall net
      income or profits of such Bank or its Lending Office imposed by the
      jurisdiction in which such Bank or its lending office is incorporated in
      which such Bank's principal executive office or Lending Office is
      located); or

            ii shall impose, modify or deem applicable any reserve, special
      deposit or similar requirement (including, without limitation, any such
      requirement imposed by the Board of Governors of the Federal Reserve
      System, but excluding with respect to any LIBOR Loans any such requirement
      included in an applicable LIBOR Reserve Percentage) against assets of,
      deposits with or for the account of, or credit extended by, any Bank (or
      its Lending Office) or shall impose on any Bank (or its Lending Office) or
      on the interbank market any other condition affecting its LIBOR Loans or
      its Notes;

and the result of any of the foregoing is to increase the cost to such Bank (or
its Lending Office) of making or maintaining any LIBOR Loan, or to reduce the
amount of any sum received or receivable by such Bank (or its Lending Office)
under this Agreement or under its Notes with respect thereto, by an amount
deemed by such Bank to be material, then, within fifteen (15) days after demand
by such Bank (with a copy to the Agent), the Borrower shall be obligated to pay
to such Bank such additional amount or amounts as will compensate such Bank for
such increased cost or reduction. In the event any law, rule, regulation or
interpretation described above is revoked, declared invalid or inapplicable or
is otherwise rescinded, and as a result thereof a Bank is determined to be
entitled to a refund from the applicable authority for any amount or amounts
which were paid or reimbursed by Borrower to such Bank hereunder, such Bank
shall refund such amount or amounts to Borrower without interest.

      (b) If, after the date hereof, any Bank or the Agent shall have determined
that the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change therein (including, without limitation, any revision in
the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal
Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225, Appendix A) or of
the Office of the Comptroller of the Currency (12 CFR Part 3,

                                       24


Appendix A), or in any other applicable capital rules heretofore adopted and
issued by any governmental authority), or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank (or its Lending Office) with any request or directive regarding
capital adequacy (whether or not having the force of law but, if not having the
force of law, compliance with which is customary in the applicable jurisdiction)
of any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Bank's capital, or on the capital
of any corporation controlling such Bank, as a consequence of its obligations
hereunder to a level below that which such Bank could have achieved but for such
adoption, change or compliance (taking into consideration such Bank's policies
with respect to capital adequacy) by an amount deemed by such Bank to be
material, then from time to time, within fifteen (15) days after demand by such
Bank (with a copy to the Agent), the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank for such reduction.

      (c) Each Bank that determines to seek compensation under this Section 9.3
shall notify the Borrower and the Agent of the circumstances that entitle the
Bank to such compensation pursuant to this Section 9.3 and will designate a
different Lending Office if such designation will avoid the need for, or reduce
the amount of, such compensation and will not, in the sole judgment of such
Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank
claiming compensation under this Section 9.3 and setting forth the additional
amount or amounts to be paid to it hereunder shall be conclusive in the absence
of manifest error. In determining such amount, such Bank may use any reasonable
averaging and attribution methods. No Bank shall be entitled to demand
compensation under this Section 9.3 for any period more than 90 days prior to
the day on which such demand is made; provided however, that the foregoing shall
in no way limit the right of any Bank to demand or receive such compensation to
the extent that such compensation relates to the retroactive application of any
law, regulation, guideline or request if such demand is made within 90 days
after the implementation of such retroactive law, interpretation, guideline or
request. A certificate as to the nature and amount of such increased cost,
submitted to the Borrower and the Agent by such Bank in good faith, shall be
conclusive and binding for all purposes, absent manifest error.

      Section 9.4 Lending Offices. Each Bank may, at its option, elect to make
its Loans hereunder at the branch, office or affiliate specified on the
appropriate signature page hereof or in the assignment agreement which any
assignee bank executes pursuant to Section 11.12 hereof (each a "Lending
Office") for each type of Loan available hereunder or at such other of its
branches, offices or affiliates as it may from time to time elect and designate
in a written notice to the Borrower and the Agent.

      Section 9.5 Discretion of Bank as to Manner of Funding. Notwithstanding
any other provision of this Agreement, each Bank shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if each Bank had actually funded and
maintained each LIBOR Loan through the purchase of deposits in the LIBOR
interbank market having a maturity corresponding to such Loan's Interest Period
and bearing an interest rate equal to LIBOR for such Interest Period.

                                       25


      SECTION 10. THE AGENT.

      Section 10.1 Appointment and Authorization of Agent. Each Bank hereby
appoints ABN AMRO Bank N.V. as the Agent under the Credit Documents and hereby
authorizes the Agent to take such action as Agent on its behalf and to exercise
such powers under the Credit Documents as are delegated to the Agent by the
terms thereof, together with such powers as are reasonably incidental thereto.
The Agent shall have no duties or responsibilities except those expressly set
forth in this Agreement and the Credit Documents. The duties of the Agent shall
be mechanical and administrative in nature; the Agent shall not have by reason
of this Agreement or any other Credit Document a fiduciary relationship in
respect of any Bank, the holder of any Note or any other Person; and nothing in
this Agreement or any other Credit Document, expressed or implied, is intended
to or shall be so construed as to impose upon the Agent any obligations in
respect of this Agreement or any other Credit Document except as expressly set
forth herein or therein.

      Section 10.2 Agent and its Affiliates. The Agent shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Bank and may exercise or refrain from exercising the same as though it
were not the Agent, and the Agent and its affiliates may accept deposits from,
lend money to, and generally engage in any kind of business with the Borrower or
any Affiliate of the Borrower as if it were not the Agent under the Credit
Documents.

      Section 10.3 Action by Agent. If the Agent receives from the Borrower a
written notice of an Event of Default pursuant to Section 7.3(c) hereof, the
Agent shall promptly give each of the Banks written notice thereof. The
obligations of the Agent under the Credit Documents are only those expressly set
forth therein. Without limiting the generality of the foregoing, the Agent shall
not be required to take any action hereunder with respect to any Default or
Event of Default, except as expressly provided in Sections 8.2 and 8.4. In no
event, however, shall the Agent be required to take any action in violation of
applicable law or of any provision of any Credit Document, and the Agent shall
in all cases be fully justified in failing or refusing to act hereunder or under
any other Credit Document unless it shall be first indemnified to its reasonable
satisfaction by the Banks against any and all costs, expense, and liability
which may be incurred by it by reason of taking or continuing to take any such
action. The Agent shall be entitled to assume that no Default or Event of
Default exists unless notified to the contrary by a Bank or the Borrower. In all
cases in which this Agreement and the other Credit Documents do not require the
Agent to take certain actions, the Agent shall be fully justified in using its
discretion in failing to take or in taking any action hereunder and thereunder.

      Section 10.4 Consultation with Experts. The Agent may consult with legal
counsel, independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken by it in good
faith in accordance with the advice of such counsel, accountants or experts.

      Section 10.5 Liability of Agent; Credit Decision. Neither the Agent nor
any of its directors, officers, agents, or employees shall be liable for any
action taken or not taken by it in connection with the Credit Documents (i) with
the consent or at the request of the Required Banks or (ii) in the absence of
its own gross negligence or willful misconduct. Neither the Agent

                                       26


nor any of its directors, officers, agents or employees shall be responsible for
or have any duty to ascertain, inquire into or verify (i) any statement,
warranty or representation made in connection with this Agreement, any other
Credit Document or any Credit Event; (ii) the performance or observance of any
of the covenants or agreements of the Borrower or any other party contained
herein or in any other Credit Document; (iii) the satisfaction of any condition
specified in Section 6 hereof, except receipt of items required to be delivered
to the Agent; or (iv) the validity, effectiveness, genuineness, enforceability,
perfection, value, worth or collectibility hereof or of any other Credit
Document or of any other documents or writing furnished in connection with any
Credit Document; and the Agent makes no representation of any kind or character
with respect to any such matter mentioned in this sentence. The Agent may
execute any of its duties under any of the Credit Documents by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Banks, the Borrower, or any other Person for the default or misconduct of any
such agents or attorneys-in-fact selected with reasonable care. The Agent shall
not incur any liability by acting in reliance upon any notice, consent,
certificate, other document or statement (whether written or oral) believed by
it to be genuine or to be sent by the proper party or parties. In particular and
without limiting any of the foregoing, the Agent shall have no responsibility
for confirming the accuracy of any Compliance Certificate or other document or
instrument received by it under the Credit Documents. The Agent may treat the
payee of any Note as the holder thereof until written notice of transfer shall
have been filed with the Agent signed by such payee in form satisfactory to the
Agent. Each Bank acknowledges that it has independently and without reliance on
the Agent or any other Bank, and based upon such information, investigations and
inquiries as it deems appropriate, made its own credit analysis and decision to
extend credit to the Borrower in the manner set forth in the Credit Documents.
It shall be the responsibility of each Bank to keep itself informed as to the
creditworthiness of the Borrower and any other relevant Person, and the Agent
shall have no liability to any Bank with respect thereto.

      Section 10.6 Indemnity. The Banks shall ratably, in accordance with their
respective Percentages, indemnify and hold the Agent, and its directors,
officers, employees, agents and representatives harmless from and against any
liabilities, losses, costs or expenses suffered or incurred by it under any
Credit Document or in connection with the transactions contemplated thereby,
regardless of when asserted or arising, except to the extent they are promptly
reimbursed for the same by the Borrower and except to the extent that any event
giving rise to a claim was caused by the gross negligence or willful misconduct
of the party seeking to be indemnified. The obligations of the Banks under this
Section 10.6 shall survive termination of this Agreement.

      Section 10.7 Resignation of Agent and Successor Agent. The Agent may
resign at any time by giving written notice thereof to the Banks and the
Borrower. Upon any such resignation of the Agent, the Required Banks shall have
the right to appoint a successor Agent with the consent of the Borrower. If no
successor Agent shall have been so appointed by the Required Banks, and shall
have accepted such appointment, within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, which shall be any Bank hereunder or
any commercial bank organized under the laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$200,000,000. Upon the acceptance of its appointment as the Agent hereunder,
such successor Agent shall thereupon succeed to and become vested with all the
rights and duties of the retiring or removed Agent under the Credit Documents,
and

                                       27


the retiring Agent shall be discharged from its duties and obligations
thereunder. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Section 10 and all protective provisions of the other Credit
Documents shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent.

      SECTION 11. MISCELLANEOUS.

      Section 11.1 Withholding Taxes. (a) Payments Free of Withholding. Subject
to Section ll.l(b) hereof, each payment by the Borrower under this Agreement or
the other Credit Documents shall be made without withholding for or on account
of any present or future taxes (other than overall net income taxes on the
recipient). If any such withholding is so required, the Borrower shall make the
withholding, pay the amount withheld to the appropriate governmental authority
before penalties attach thereto or interest accrues thereon and forthwith pay
such additional amount as may be necessary to ensure that the net amount
actually received by each Bank and the Agent free and clear of such taxes
(including such taxes on such additional amount) is equal to the amount which
that Bank or the Agent (as the case may be) would have received had such
withholding not been made. If the Agent or any Bank pays any amount in respect
of any such taxes, penalties or interest the Borrower shall reimburse the Agent
or that Bank for that payment on demand. If the Borrower pays any such taxes,
penalties or interest, it shall deliver official tax receipts evidencing that
payment or certified copies thereof to the Bank or Agent on whose account such
withholding was made (with a copy to the Agent if not the recipient of the
original) on or before the thirtieth day after payment. If any Bank or the Agent
determines it has received or been granted a credit against or relief or
remission for, or repayment of, any taxes paid or payable by it because of any
taxes, penalties or interest paid by the Borrower and evidenced by such a tax
receipt, such Bank or Agent shall, to the extent it can do so without prejudice
to the retention of the amount of such credit, relief, remission or repayment,
pay to the Borrower such amount as such Bank or Agent determines is attributable
to such deduction or withholding and which will leave such Bank or Agent (after
such payment) in no better or worse position than it would have been in if the
Borrower had not been required to make such deduction or withholding. Nothing in
this Agreement shall interfere with the right of each Bank and the Agent to
arrange its tax affairs in whatever manner it thinks fit nor oblige any Bank or
the Agent to disclose any information relating to its tax affairs or any
computations in connection with such taxes.

      (b) U.S. Withholding Tax Exemptions. Each Bank that is not a United States
person (as such term is defined in Section 7701(a)(30) of the Code) shall submit
to the Borrower and the Agent on or before the earlier of the date the initial
Borrowing is made hereunder and thirty (30) days after the date hereof, two duly
completed and signed copies of either Form W8BEN (relating to such Bank and
entitling it to a complete exemption from withholding under the Code on all
amounts to be received by such Bank, including fees, pursuant to the Credit
Documents and the Loans) or Form W8ECI (relating to all amounts to be received
by such Bank, including fees, pursuant to the Credit Documents and the Loans of
the United States Internal Revenue Service. Thereafter and from time to time,
each Bank shall submit to the Borrower and the Agent such additional duly
completed and signed copies of one or the other of such Forms (or such successor
forms as shall be adopted from time to time by the relevant United States taxing
authorities) as may be (i) requested by the Borrower in a written notice,
directly or through the Agent, to such Bank and (ii) required under then current
United States law or regulations to

                                       28


avoid or reduce United States withholding taxes on payments in respect of all
amounts to be received by such Bank, including fees, pursuant to the Credit
Documents or the Loans.

      (c) Inability of Bank to Submit Forms. If any Bank determines, as a result
of any change in applicable law, regulation or treaty, or in any official
application or interpretation thereof, that it is unable to submit to the
Borrower or Agent any form or certificate that such Bank is obligated to submit
pursuant to subsection (b) of this Section 11.1. or that such Bank is required
to withdraw or cancel any such form or certificate previously submitted or any
such form or certificate otherwise becomes ineffective or inaccurate, such Bank
shall promptly notify the Borrower and Agent of such fact and the Bank shall to
that extent not be obligated to provide any such form or certificate and will be
entitled to withdraw or cancel any affected form or certificate, as applicable.

      Section 11.2 No Waiver of Rights. No delay or failure on the part of the
Agent or any Bank or on the part of the holder or holders of any Note in the
exercise of any power or right under any Credit Document shall operate as a
waiver thereof, nor as an acquiescence in any default, nor shall any single or
partial exercise thereof preclude any other or further exercise of any other
power or right, and the rights and remedies hereunder of the Agent, the Banks
and the holder or holders of any Notes are cumulative to, and not exclusive of,
any rights or remedies which any of them would otherwise have.

      Section 11.3 Non-Business Day. If any payment of principal or interest on
any Loan or of any other Obligation shall fall due on a day which is not a
Business Day, interest or fees (as applicable) at the rate, if any, such Loan or
other Obligation bears for the period prior to maturity shall continue to accrue
on such Obligation from the stated due date thereof to and including the next
succeeding Business Day, on which the same shall be payable.

      Section 11.4 Documentary Taxes. The Borrower agrees that it will pay any
documentary, stamp or similar taxes payable in respect to any Credit Document,
including interest and penalties, in the event any such taxes are assessed,
irrespective of when such assessment is made and whether or not any credit is
then in use or available hereunder.

      Section 11.5 Survival of Representations. All representations and
warranties made herein or in certificates given pursuant hereto shall survive
the execution and delivery of this Agreement and the other Credit Documents, and
shall continue in full force and effect with respect to the date as of which
they were made as long as any credit is in use or available hereunder.

      Section 11.6 Survival of Indemnities. All indemnities and all other
provisions relative to reimbursement to the Banks of amounts sufficient to
protect the yield of the Banks with respect to the Loans, including, but not
limited to, Section 2.11, Section 9.3 and Section 11.15 hereof, shall survive
the termination of this Agreement and the other Credit Documents and the payment
of the Loans and all other Obligations.

      Section 11.7 Set-Off. (a) In addition to any rights now or hereafter
granted under applicable law and not by way of limitation of any such rights,
upon the occurrence of any Event of Default, each Bank and each subsequent
holder of any Note is hereby authorized by the

                                       29


Borrower at any time or from time to time, without notice to the Borrower or to
any other Person, any such notice being hereby expressly waived, to set off and
to appropriate and to apply any and all deposits (general or special, including,
but not limited to, Indebtedness evidenced by certificates of deposit, whether
matured or unmatured, and in whatever currency denominated) and any other
Indebtedness at any time held or owing by that Bank or that subsequent holder to
or for the credit or the account of the Borrower, whether or not matured,
against and on account of the obligations and liabilities of the Borrower to
that Bank or that subsequent holder under the Credit Documents, including, but
not limited to, all claims of any nature or description arising out of or
connected with the Credit Documents, irrespective of whether or not (a) that
Bank or that subsequent holder shall have made any demand hereunder or (b) the
principal of or the interest on the Loans or Notes and other amounts due
hereunder shall have become due and payable pursuant to Section 8 and although
said obligations and liabilities, or any of them, may be contingent or
unmatured.

      (b) Each Bank agrees with each other Bank a party hereto that if such Bank
shall receive and retain any payment, whether by set-off or application of
deposit balances or otherwise, on any of the Loans in excess of its ratable
share of payments on all such obligations then outstanding to the Banks, then
such Bank shall purchase for cash at face value, but without recourse, ratably
from each of the other Banks such amount of the Loans, or participations
therein, held by each such other Banks (or interest therein) as shall be
necessary to cause such Bank to share such excess payment ratably with all the
other Banks; provided, however, that if any such purchase is made by any Bank,
and if such excess payment or part thereof is thereafter recovered from such
purchasing Bank, the related purchases from the other Banks shall be rescinded
ratably and the purchase price restored as to the portion of such excess payment
so recovered, but without interest.

      Section 11.8 Notices. Except as otherwise specified herein, all notices
under the Credit Documents shall be in writing (including facsimile or other
electronic communication) and shall be given to a party hereunder at its address

the Borrower and its successors and assigns, and shall inure to the benefit of
each of the Banks and the benefit of their respective successors, and assigns,
including any subsequent holder of any Note. The Borrower may not assign any of

      Section 11.11 [Intentionally Omitted].

      Section 11.12 Assignments, Participations, Etc.

      (a) Successors and Assigns Generally. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that the Borrower may
not assign or otherwise transfer any of

                                       31


its rights or obligations hereunder without the prior written consent of each
Bank and no Bank may assign or otherwise transfer any of its rights or
obligations hereunder except (i) to an Eligible Assignee in accordance with the
provisions of paragraph (b) of this Section, (ii) by way of participation in
accordance with the provisions of paragraph (d) of this Section or (iii) by way
of pledge or assignment of a security interest subject to the restrictions of
paragraph (f) of this Section (and any other attempted assignment or transfer by
any party hereto shall be null and void). Nothing in this Agreement, expressed
or implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby, Participants
to the extent provided in paragraph (d) of this Section and, to the extent
expressly contemplated hereby, the affiliates of each of the Agent and the
Banks) any legal or equitable right, remedy or claim under or by reason of this
Agreement.

      (b) Assignments by Banks. Any Bank may at any time assign to one or more
Eligible Assignees all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Revolving Credit Commitment and the
Loans at the time owing to it); provided that

            i except in the case of an assignment of the entire remaining amount
      of the assigning Bank's Revolving Credit Commitment and the Loans at the
      time owing to it or in the case of an assignment to a Bank or an Affiliate
      of a Bank or an Approved Fund with respect to a Bank, the aggregate amount
      of the Revolving Credit Commitment (which for this purpose includes Loans
      outstanding thereunder) or, if the applicable Revolving Credit Commitment
      is not then in effect, the principal outstanding balance of the Loan of
      the assigning Bank subject to each such assignment (determined as of the
      date the Assignment and Assumption with respect to such assignment is
      delivered to the Agent or, if "Trade Date" is specified in the Assignment
      and Assumption, as of the Trade Date) shall not be less than $5,000,000
      (and the remaining aggregate amount of the Revolving Credit Commitment of
      such assigning Bank shall not be less than $5,000,000 after giving effect
      to such assignment), unless each of the Agent and, so long as no Event of
      Default has occurred and is continuing, the Borrower otherwise consents
      (each such consent not to be unreasonably withheld or delayed);

            ii each partial assignment shall be made as an assignment of a
      proportionate part of all the assigning Bank's rights and obligations
      under this Agreement with respect to the Loan or the Revolving Credit
      Commitment assigned;

            iii any assignment of a Revolving Credit Commitment must be approved
      by the Agent and, so long as no Event of Default has occurred and is
      continuing, the Borrower, unless the Person that is the proposed assignee
      is itself an Eligible Assignee, which approval shall not be unreasonably
      withheld; and

            iv the parties to each assignment shall execute and deliver to the
      Agent an Assignment and Assumption, together with a processing and
      recordation fee of $3,500, and the Eligible Assignee, if it shall not be a
      Bank, shall deliver to the Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Agent pursuant to paragraph
(c) of this Section, from and after the effective date specified in each
Assignment and Assumption, the

                                       32


Eligible Assignee thereunder shall be a party to this Agreement and, to the
extent of the interest assigned by such Assignment and Assumption, have the
rights and obligations of a Bank under this Agreement, and the assigning Bank
thereunder shall, to the extent of the interest assigned by such Assignment and
Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Bank's rights
and obligations under this Agreement, such Bank shall cease to be a party
hereto) but shall continue to be entitled to the benefits of Sections 9.3 and
11.1 with respect to facts and circumstances occurring prior to the effective
date of such assignment. Any assignment or transfer by a Bank of rights or
obligations under this Agreement that does not comply with this paragraph shall
be treated for purposes of this Agreement as a sale by such Bank of a
participation in such rights and obligations in accordance with paragraph (d) of
this Section.

      (c) Register. The Agent, acting solely for this purpose as an agent of the
Borrower, shall maintain at one of its offices in Chicago, Illinois a copy of
each Assignment and Assumption delivered to it and a register for the
recordation of the names and addresses of the Banks, and the Revolving Credit
Commitments of, and principal amounts of the Loans owing to, each Bank pursuant
to the terms hereof from time to time (the "Register"). The entries in the
Register shall be conclusive, and the Borrower, the Agent and the Banks may
treat each Person whose name is recorded in the Register pursuant to the terms
hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding
notice to the contrary. The Register shall be available for inspection by the
Borrower and any Bank at any reasonable time upon reasonable prior notice.

      (d) Participations. Any Bank may at any time, without the consent of, or
notice to, the Borrower or the Agent, sell participations to any Person (other
than a natural person or a Borrower or any of the Borrower's Affiliates or
Subsidiaries) (each, a "Participant") in all or a portion of such Bank's rights
and/or obligations under this Agreement (including all or a portion of its
Revolving Credit Commitment and/or the Loans owing to it); provided that (i)
such Bank's obligations under this Agreement shall remain unchanged, (ii) such
Bank shall remain solely responsible to the other parties hereto for the
performance of such obligations and (iii) the Borrower, the Agent and the other
Banks shall continue to deal solely and directly with such Bank in connection
with such Bank's rights and obligations under this Agreement.

      Any agreement or instrument pursuant to which a Bank sells such a
participation shall provide that such Bank shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
provide that such Bank will not, without the consent of the Participant, agree
to any amendment, modification or waiver of the type described in Section
11.13(i) that directly affects such Participant. Subject to paragraph (e) of
this Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Section 2.11, Section 9.3 and Section 11.7 to the same extent as if
it were a Bank and had acquired its interest by assignment pursuant to paragraph
(b) of this Section. Each Bank granting a participation under this Section
11.11(d) shall keep a register, meeting the requirements of Treasury Regulation
Section 5f.103-1(c), of each participant, specifying such participant's
entitlement to payments of principal and interest with respect to such
participation.

                                       33


      (e) Limitations upon Participant Rights. A Participant shall not be
entitled to receive any greater payment under Section 2.11, Section 9.3 or
Section 11.7 than the applicable Bank would have been entitled to receive with
respect to the participation sold to such Participant, unless the sale of the
participation to such Participant is made with the Borrower's prior written
consent.

      (f) Certain Pledges. Any Bank may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Bank, including without limitation any pledge or assignment
to secure obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release such Bank from any of its obligations hereunder or
substitute any such pledgee or assignee for such Bank as a party hereto.

      (g) Certain Funding Arrangements. Notwithstanding anything to the contrary
contained herein, any Bank (a "Granting Bank") may grant to a special purpose
funding vehicle (a "SPC"), identified as such in writing from time to time by
the Granting Bank to the Agent and the Borrower, the option to provide to the
Borrower all or any part of any Loan that such Granting Bank would otherwise be
obligated to make to the Borrower pursuant to this Agreement; provided that (i)
nothing herein shall constitute a commitment by any SPC to make any Loan, (ii)
if an SPC elects not to exercise such option or otherwise fails to provide all
or any part of such Loan, the Granting Bank shall be obligated to make such Loan
pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall
utilize the Revolving Credit Commitment of the Granting Bank to the same extent,
and as if, such Loan were made by such Granting Bank. Each party hereto hereby
agrees that no SPC shall be liable for any indemnity or similar payment
obligation under this Agreement (all liability for which shall remain with the
Granting Bank). In furtherance of the foregoing, each party hereto hereby agrees
(which agreement shall survive the termination of this Agreement) that, prior to
the date that is one year and one day after the payment in full of all
outstanding commercial paper or other senior indebtedness of any SPC, it will
not institute against, or join any other person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any State thereof arising out
of any claim relating to the Credit Documents. In addition, notwithstanding
anything to the contrary contained in this Section 11.12(b), any SPC may (i)
with notice to, but without the prior written consent of, the Borrower and the
Agent and without paying any processing fee therefor, assign all or a portion of
its interests in any Loan to the Granting Bank or to any financial institutions
(consented to by the Borrower and Agent) providing liquidity and/or credit
support to or for the account of such SPC to support the funding or maintenance
of Loans and (ii) disclose on a confidential basis any non-public information
relating to its Loans to any rating agency, commercial paper dealer or provider
of any surety, guarantee or credit or liquidity enhancement to such SPC. This
section may not be amended without the written consent of the SPC.

      Section 11.13 Amendments. Any provision of the Credit Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by (a) the Borrower, (b) the Required Banks, and (c) if the rights or
duties of the Agent are affected thereby, the Agent; provided that:

            i   no amendment or waiver pursuant to this Section. 11.13 shall (A)
      increase, decrease or extend any Revolving Credit Commitment of any Bank
      without the consent

                                       34


      of such Bank or (B) reduce the amount of or postpone any fixed date for
      payment of any principal of or interest on any Loan or of any fee payable
      hereunder without the consent of each Bank; and

            ii   no amendment or waiver pursuant to this Section 11.13 shall,
      unless signed by each Bank, change this Section 11.13, or the definition
      of Required Banks, or affect the number of Banks required to take any
      action under the Credit Documents.

      Anything in this Agreement to the contrary notwithstanding, if any time
when the conditions precedent set forth in Section 6.2 hereof to any Loan
hereunder are satisfied, any Bank shall fail to fulfill its obligations to make
such Loan (any such Bank, a "Defaulting Bank") then, for so long as such failure
shall continue, the Defaulting Bank shall (unless the Borrower and the Required
Banks determined as if the Defaulting Bank were not a Bank hereunder, shall
otherwise consent in writing) be deemed for all purposes related to amendments,
modifications, waivers or consents under this Agreement (other than amendments
or waivers referred to in clause (i) and (ii) above) to have no Loans or
Revolving Credit Commitments, shall not be treated as a Bank hereunder when
performing the computation of the Required Banks.

      Section 11.14 Headings. Section headings used in this Agreement are for
reference only and shall not affect the construction of this Agreement.

      Section 11.15 Legal Fees, Other Costs and Indemnification. The Borrower
agrees to pay all reasonable costs and expenses of the Agent in connection with
the preparation and negotiation of the Credit Documents, including without
limitation, the reasonable fees and disbursements of counsel to the Agent, in
connection with the preparation and execution of the Credit Documents, and any
amendment, waiver or consent related hereto, whether or not the transactions
contemplated herein are consummated. The Borrower further agrees to indemnify
each Bank, the Agent, and their respective directors, agents, officers and
employees, against all losses, claims, damages, penalties, judgments,
liabilities and expenses (including, without limitation, all reasonable expenses
of litigation or preparation therefor, whether or not the indemnified Person is
a party thereto) which any of them may incur or reasonably pay arising out of or
relating to any Credit Document or any of the transactions contemplated thereby
or the direct or indirect application or proposed application of the proceeds of
any Loan, other than those which arise from the gross negligence or willful
misconduct of the party claiming indemnification. The Borrower, upon demand by
the Agent or a Bank at any time, shall reimburse the Agent or Bank for any
reasonable legal or other expenses (including reasonable allocable fees and
expenses of in-house counsel) incurred in connection with investigating or
defending against any of the foregoing except if the same is directly due to the
gross negligence or willful misconduct of the party to be indemnified.

      Section 11.16 [Reserved].

      Section 11.17 Entire Agreement. The Credit Documents constitute the entire
understanding of the parties thereto with respect to the subject matter thereof
and any prior or contemporaneous agreements, whether written or oral, with
respect thereto are superseded thereby.

                                       35


      Section 11.18 Construction. The parties hereto acknowledge and agree that
neither this Agreement nor the other Credit Documents shall be construed more
favorably in favor of one than the other based upon which party drafted the
same, it being acknowledged that all parties hereto contributed substantially to
the negotiation of this Agreement and the other Credit Documents.

      Section 11.19 Governing Law. This Agreement and the other Credit
Documents, and the rights and duties of the parties hereto, shall be construed
and determined in accordance with the internal laws of the State of Illinois.

      Section 11.20 SUBMISSION TO JURISDICTION; WAIVER OF JURY TRIAL. THE
BORROWER HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES
DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS AND OF ANY ILLINOIS STATE
COURT SITTING IN THE CITY OF CHICAGO FOR PURPOSES OF ALL LEGAL PROCEEDINGS
ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT DOCUMENTS OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. THE BORROWER IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT
AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT
IN AN INCONVENIENT FORUM. THE BORROWER HEREBY IRREVOCABLY WAIVES ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY
CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

      Section 11.21 Confidentiality. The Agent and the Banks shall hold all
non-public information provided to them by Borrower pursuant to or in connection
with this Agreement in accordance with their customary procedures for handling
confidential information of this nature, but may make disclosure to any of their
examiners, regulators, Affiliates, outside auditors, counsel and other
professional advisors in connection with this Agreement or any other Credit
Document or as reasonably required by any potential bona fide transferee,
participant or assignee, or in connection with the exercise of remedies under a
Credit Document, or to any nationally recognized rating agency that requires
access to information about a Bank's investment portfolio in connection with
ratings issued with respect to such Bank, or as requested by any governmental
agency or representative thereof or pursuant to legal process; provided,
however, that unless specifically prohibited by applicable law or court order,
the Agent and each Bank shall use reasonable efforts to promptly notify Borrower
of any request by any governmental agency or representative thereof (other than
any such request in connection with an examination of the financial condition of
the Agent or such Bank by such governmental agency) for disclosure of any such
non-public information and, where practicable, prior to disclosure of such
information. Prior to any such disclosure pursuant to this Section 11.21, the
Agent and each Bank shall require any such bona fide transferee, participant and
assignee receiving a disclosure of non-public information to agree, for the
benefit of Borrower, in writing to be bound by this Section 11.21; and to
require such Person to require any other Person to whom such Person discloses
such non-public information to be similarly bound by this Section 11.21. Neither
the Agent nor any Bank shall be required to hold confidential any information

                                       36


that becomes public by any means other than as a result of a breach by it of its
obligations under this Section 11.21.

      Section 11.22 Patriot Act. As required by federal law or the
Administrative Agent or a Bank's polices and practices, the Administrative Agent
or a Bank may need to collect certain customer identification information and
documentation in connection with opening or maintaining accounts or establishing
or continuing to provide services.

                                       37


      In Witness Whereof, the parties hereto have caused this Agreement to be
duly executed and delivered in Chicago, Illinois by their duly authorized
officers as of the day and year first above written.

                                      NOTE

                                                                  August 4, 2004

      FOR VALUE RECEIVED, the undersigned, The Peoples Gas Light and Coke
Company., an Illinois corporation (the "BORROWER"), promises to pay to the order
of [___________________________](the "Bank") on the Termination Date of the
hereinafter defined Credit Agreement, at the principal office of ABN AMRO Bank
N.V., in Chicago, Illinois, in U.S. Dollars in accordance with Section 4.1 of
the Credit Agreement, the aggregate unpaid principal of all Loans made by the
Bank to the Borrower pursuant to the Credit Agreement, together with interest on
the principal amount of each Loan from time to time outstanding hereunder at the
rates, and payable in the manner and on the dates, specified in the Credit
Agreement.

      The Bank shall record on its books or records or on a schedule attached to
this Note, which is a part hereof, each Loan made by it pursuant to the Credit
Agreement, together with all payments of principal and interest and the
principal balances from time to time outstanding hereon, whether the Loan is a
Base Rate Loan or a LIBOR Loan and the interest rate and Interest Period
applicable thereto, provided that prior to the transfer of this Note all such
amounts shall be recorded on a schedule attached to this Note. The record
thereof, whether shown on such books or records or on a schedule to this Note,
shall be prima facie evidence of the same, provided, however, that the failure
of the Bank to record any of the foregoing or any error in any such record shall
not limit or otherwise affect the obligation of the Borrower to repay all Loans
made to it pursuant to the Credit Agreement together with accrued interest
thereon.

      This Note is one of the Notes referred to in the Credit Agreement dated as
of August 4, 2004, among the Borrower, ABN AMRO Bank N.V., as Agent, and the
Banks party thereto (the "Credit Agreement"), and this Note and the holder
hereof are entitled to all the benefits provided for thereby or referred to
therein, to which Credit Agreement reference is hereby made for a statement
thereof. This Note may only be conveyed, transferred, assigned or otherwise
negotiated to a holder in accordance with the terms of the Credit Agreement. All
defined terms used in this Note, except terms otherwise defined herein, shall
have the same meaning as in the Credit Agreement. This Note shall be governed by
and construed in accordance with the internal laws of the State of Illinois.

      Prepayments may be made hereon and this Note may be declared due prior to
the expressed maturity hereof, all in the events, on the terms and in the manner
as provided for in the Credit Agreement.

      The Borrower hereby waives demand, presentment, protest or notice of any
kind hereunder.

ABN AMRO Bank N.V., as Agent
135 South LaSalle Street
Chicago, Illinois 60603

      Re: The Peoples Gas Light and Coke Company

Ladies and Gentlemen:

            We have acted as legal counsel to The Peoples Gas Light and Coke
Company, an Illinois corporation (the "Borrower"), in connection with the
transactions contemplated by the unsecured revolving credit facility established
by that certain Credit Agreement dated as of the date hereof (the "Credit
Agreement") among the Borrower, the financial institutions from time to time
party thereto (each a "Bank" and collectively the "Banks") and ABN AMRO Bank
N.V. in its capacity as agent for the Banks. This opinion is furnished to you
pursuant to Section 6.1(a) of the Credit Agreement. Unless otherwise defined
herein, terms used herein have the meanings provided for in the Credit
Agreement.

                              I. DOCUMENTS REVIEWED

            In connection with this opinion letter, we have examined the
following documents:

            (a) the Credit Agreement dated the date hereof; and

            (b) the form of Note dated the date hereof.

The documents referred to in clauses (a) and (b) above are referred to
collectively as the "Subject Documents".

            In addition, we have examined the following:

                        (i) originals, or copies identified to our satisfaction
            as being true copies, of such records, documents and other
            instruments as we have deemed necessary for the purposes of this
            opinion letter;

                        (ii) certificates from the secretary or other
            appropriate representative of the Borrower certifying in each
            instance as to true and

            correct copies of the charter, bylaws and board of directors
            resolutions, of the Borrower (the "Organizational Documents") and as
            to the incumbency and specimen signatures of officers or other
            persons authorized to execute the Subject Documents on behalf of the
            Borrower;

                        (iii) with respect to the Borrower, a certificate issued
            by the Secretary of State of the State of Illinois attesting to the
            continued existence and good standing of the Borrower in such state
            (the "Good Standing Certificate"); and

                        (iv) a Certificate of the Borrower, a copy of which is
            attached as Annex A hereto (the "Borrower's Certificate"), together
            with the agreements and instruments referred to therein
            (collectively, the "Reviewed Agreements").

                     II. ASSUMPTIONS UNDERLYING OUR OPINIONS

            For all purposes of the opinions expressed herein, we have assumed,
without independent investigation, that:

            (a) Factual Matters. With regard to factual matters, to the extent
that we have reviewed and relied upon (a) certificates of the Borrower, (b)
representations of the Borrower set forth in the Subject Documents and (c)
certificates and assurances from public officials, all of such certificates,
representations and assurances are accurate;

            (b) Contrary Knowledge of Addressee. No addressee of this opinion
letter has any actual knowledge that any of our factual assumptions or opinions
is inaccurate;

            (c) Signatures. The signatures of individuals (other than
individuals signing on behalf of the Borrower) signing the Subject Documents are
genuine and authorized;

            (d) Authentic and Conforming Documents. All documents submitted to
us as originals are authentic, complete and accurate and all documents submitted
to us as copies conform to authentic original documents;

            (e) Capacity of Certain Parties. All parties to the Subject
Documents (other than the Borrower) have the capacity and full power and
authority to execute, deliver and perform the Subject Documents and the
documents required or permitted to be delivered and performed thereunder;

            (f) Subject Documents Binding on Certain Parties. Except with
respect to the Borrower, all of the Subject Documents and the documents required
or permitted to be delivered thereunder have been duly authorized by all
necessary corporate or other action on the part of the parties thereto, have
been duly executed and delivered by such parties and are legal, valid and
binding obligations enforceable against such parties in accordance with their
terms;

                                        2


August _, 2004
Page 3 of 7

            (g) Consents for Certain Parties. All necessary consents,
authorizations, approvals, permits or certificates (governmental and otherwise)
which are required as a condition to the execution and delivery of the Subject
Documents by the parties thereto (other than the Borrower) and to the
consummation by such parties of the transactions contemplated thereby have been
obtained; and

            (h) Accurate Description of Parties' Understanding. The Subject
Documents accurately describe and contain the mutual understanding of the
parties, and there are no oral or written statements or agreements that modify,
amend or vary, or purport to modify, amend or vary, any of the terms thereof.

                                III. OUR OPINIONS

            Based on and subject to the foregoing and the other limitations,
assumptions, qualifications and exclusions set forth in this opinion letter, we
are of the opinion that:

            (a) Organizational Status. Based solely upon the Good Standing
Certificate, the Borrower is validly existing and in good standing under the
laws of the State of Illinois as of the date set forth in the applicable Good
Standing Certificate.

            (b) Power and Authority. The Borrower has the organizational power
and authority to execute, deliver and perform the terms and provisions of each
Subject Document and has taken all necessary organizational action to authorize
the execution, delivery and performance thereof.

            (c) Execution, Validity and Enforceability. The Borrower has duly
executed and delivered each Subject Document and each such Subject Document
constitutes its valid, binding and enforceable obligation.

            (d) Noncontravention. Neither the execution, delivery and
performance by the Borrower of any Subject Document, nor the compliance by the
Borrower with the terms and provisions thereof: (i) violates any present law,
statute or regulation of the State of Illinois or the United States that, in
each case, is applicable to the Borrower (including, without limitation, the
United States Public Utility Holding Company Act of 1935); (ii) violates any
provision of the Organizational Documents of the Borrower; or (iii) results in
any breach of any of the terms of, or constitutes a default under, any Reviewed
Agreement or results in the creation or imposition of any lien, security
interest or other encumbrance (except as contemplated by the Subject Documents)
upon any assets of the Borrower pursuant to the terms of any Reviewed Agreement.

            (e) Governmental Approvals. No consent, approval or authorization
of, or filing with, any governmental authority of the State of Illinois or the
United States that, in each case, is applicable to the Borrower is required for
(i) the due execution, delivery and performance by the Borrower of any Subject
Document or (ii) the validity, binding effect or enforceability of any Subject
Document, except (A) in each case as have previously been made or obtained and
(B) consents, approvals, authorizations or filings as may be

                                        3


August _, 2004
Page 4 of 7

required to be obtained or made by the Banks as a result of its involvement in
the transactions contemplated by the Subject Documents.

            (f) The Borrower is a public utility within the meaning of Section
3-105 of the Illinois Public Utilities Act (the "Public Utilities Act"), 220
ILCS 5/1-101 et seq. Pursuant to Section 6-102(c) of the Public Utilities Act,
the Borrower is not required to obtain the approval of the Illinois Commerce
Commission for the execution and performance of the Credit Agreement.

                                 IV. EXCLUSIONS

other laws and regulations governing the development, use and occupancy of real
property, federal and state antitrust and unfair competition laws and

            of termination of the Credit Agreement; or

                        (vi) obligations to make an agreement in the future;

            (h) Remedies. Any provision in any Subject Document to the effect
that rights or remedies are not exclusive, that every right or remedy is
cumulative and may be exercised in addition to any other right or remedy, that
the election of some particular remedy does not preclude recourse to one or more
others or that failure to exercise or delay in exercising rights or remedies
will not operate as a waiver of any such right or remedy.

to preferences and fraudulent transfers or conveyances), reorganization,
moratorium and other similar laws affecting creditors' rights generally.

            (c) Equitable Principles. Our opinions are subject to the effect of
general principles of equity (regardless of whether considered in a proceeding
in equity or at law), including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing. In applying such principles, a
court, among other things, might limit the availability of specific equitable
remedies (such as injunctive relief and the remedy of specific performance),
might not allow a creditor to accelerate maturity of debt or exercise other
remedies upon the occurrence of a default deemed immaterial or for non-credit
reasons or might decline to order a debtor to perform covenants in a Subject
Document. Further, a court may refuse to enforce a covenant if and to the extent
that it deems such covenant to be violative of applicable public policy,
including, for example,

                                        5

provisions requiring indemnification of the Banks against liability for its own
wrongful or negligent acts.

            (d) Noncontravention and Governmental Approvals. With respect to the
opinions expressed in paragraphs III-(d)(i), III-(e) and III-(f), our opinions
are limited (i) to our actual knowledge, if any, of the Borrower's specially
regulated business activities and properties based solely upon the Borrower's
Certificate in respect of such matters and without any independent investigation
or verification on our part and (ii) to our review of only those laws and
regulations that, in our experience, are normally applicable to transactions of
the type contemplated by the Subject Documents.

            (e) Knowledge. Whenever our opinions are stated to be "to our
knowledge" or "known to us" (or words of similar import), it means the actual
knowledge of the particular McGuireWoods LLP attorneys who have represented the
Borrower in connection with the Subject Documents and who have given substantive
attention to the preparation and negotiation thereof - namely, John G. Nassos,
Craig R. Culbertson, Mary Klyasheff and Simon B. Halfin. Except as expressly set
forth herein, we have not undertaken any independent investigation (including,
without limitation, conducting any review, search or investigation of any public
files or records or dockets or any review of our files) to determine the
existence or absence of any facts, and no inference as to our knowledge
concerning such facts should be drawn from our reliance on the same in
connection with the preparation and delivery of this opinion letter.

            (f) Reviewed Agreements. With respect to our opinion in paragraph
III-(d), we have assumed that the law governing each of the Reviewed Agreement
would have the same effect as the law of the State of Illinois and we express no
opinion as to any violation not readily ascertainable from the face of any
Reviewed Agreement or arising from any cross-default provision insofar as it
relates to a default under an agreement that is not a Reviewed Agreement or
arising under a covenant of a financial or numerical nature or requiring
computation.

            (g) Material Changes to Terms. Provisions in the Subject Documents
which provide that any obligations of the Borrower will not be affected by the
action or failure to act on the part of the Banks or by an amendment or waiver
of the provisions contained in the other Subject Documents might not be
enforceable under circumstances in which such action, failure to act, amendment
or waiver so materially changes the essential terms of the obligations that, in
effect, a new contract has arisen between the Banks and the Borrower.

            (h) Incorporated Documents. This opinion does not relate to (and we
have not reviewed) any documents or instruments other than the Subject Documents
and the Reviewed Agreements, and we express no opinion as to such other
documents or instruments (including, without limitation, any documents or
instruments referenced or incorporated in any of the Subject Documents) or as to
the interplay between the Subject Documents and any such other documents and
instruments.

            (i) Mathematical Calculations. We have made no independent
verification of any of the numbers, schedules, formulae or calculations in the
Subject Documents, and we render no opinion with regard to the accuracy,
validity or enforceability of any of them.

                            VI. RELIANCE ON OPINIONS

            The foregoing opinions are being furnished to the Banks for the
purpose referred to in the first paragraph of this opinion letter, and this
opinion letter is not to be furnished to any other person or entity or used or
relied upon for any other purpose without our prior written consent. The
opinions set forth herein are made as of the date hereof, and we assume no
obligation to supplement this opinion letter if any applicable laws change after
the date hereof or if we become aware after the date hereof of any facts that
might change the opinions expressed herein.

                                        Very truly yours,

                                        7


                                                                         Annex A

                     THE PEOPLES GAS LIGHT AND COKE COMPANY
                             BORROWER'S CERTIFICATE

            Reference is made to the opinion letter of McGuire Woods LLP (the
"Opinion Letter") delivered in connection with the Credit Agreement dated as of
the date hereof (the "Credit Agreement") among The Peoples Gas Light and Coke
Company (the "Borrower"), the financial institutions from time to time party
thereto (each a "Bank" and collectively the "Banks") and ABN AMRO Bank N.V., as
agent for the Banks. Capitalized terms used in this Certificate and not
otherwise defined have the meanings assigned to such terms in the Opinion
Letter.

            The undersigned, Douglas M. Ruschau, Vice President and Treasurer of
the Borrower certifies, in connection with the execution, delivery and
performance by the Borrower of the Subject Documents, the consummation of the
transactions contemplated by the Subject Documents and issuance by McGuireWoods
LLP of the Opinion Letter, as follows:

            1. Attached as Schedule I hereto is a list of all indentures,
mortgages, deeds of trust, bonds, notes, security or pledge agreements,
guarantees, loan or credit agreements and other agreements or instruments which
affect or purport to affect the ability of the Borrower to borrow money, to
guaranty the obligations of other persons or entities, to create security
interests, liens, or other encumbrances in or on its property or to undertake
and perform its obligations under the Credit Agreement or any other Subject
Documents. A true and complete copy of each of the above agreements and
instruments has been previously furnished to McGuireWoods LLP. No default or
event of default or violation of any such agreements, instruments, decrees or
orders exists both before and immediately giving effect to the transactions
contemplated by the Subject Documents.

            2. The Borrower is a public utility within the meaning of Section
3-105 of the Illinois Public Utilities Act (the "Public Utilities Act"), 220
ILCS 5/1-101 et seq. and does not directly or through a Subsidiary conduct
business in any other state that would subject the Company to regulation as a
public utility by any other jurisdiction outside the State of Illinois.IN
WITNESS WHEREOF, I have signed the Certificate in my capacity as Vice President
and Treasurer of the Borrower this____________day of August, 2004.
