Commitment. Subject to the terms and conditions of this Agreement, the Company
may borrow, repay and reborrow at any time prior to the Revolving Termination
Date. The Commitments shall expire on the Revolving Termination Date.

Company submits a notice in writing to the Agent (which shall promptly notify

Eurodollar Advances (each a "Type" of Advance), or a combination thereof, as
selected by the Company in accordance with Sections 2.8 and 2.9.

      (a) The Company agrees to pay to the Agent for the account of each Bank
according to its Pro Rata Share a commitment fee (the "Commitment Fee") at the
Commitment Fee Rate on the daily Unused Commitment from the Effective Date to
but not including the date on which this Agreement is terminated in full and all
of the Obligations hereunder have been paid in full. The fees payable pursuant
to this clause (a) shall be payable quarterly in arrears on each Payment Date
(for the quarter then most recently ended) and on the Revolving Termination Date
or, if the Company exercises the Term Out Option, the Final Maturity Date (for
the period then ended for which such fee has not previously been paid) and shall
be calculated for actual days elapsed on the basis of a 360 day year.

      (b) The Company may permanently reduce the Aggregate Commitment in whole,
or in part ratably among the Banks in the minimum amount of $10,000,000 (and in
multiples of $1,000,000 if in excess thereof), upon at least five Business Days'
written notice to the Agent, which notice shall specify the amount of any such
reduction; provided that the Aggregate Commitment may not be reduced below the
Aggregate Outstandings. All accrued Commitment Fees shall be payable on the
effective date of any termination of the obligation of the Banks to make
Advances hereunder. Upon any permanent reduction in the Aggregate Commitment
pursuant to the terms of this Section 2.5(b) after the FMB Issue Date, the Agent
shall, upon request of the Company, promptly surrender to or upon the order of
the Company one or more Bonds specified by the Company; provided that the
Company remains in compliance with Section 6.10.

      (c) The Company may, from time to time, by means of a letter delivered to
the Agent substantially in the form of Exhibit H, request that the Aggregate
Commitment be increased by up to $200,000,000 (in the aggregate during the term
of this Agreement) by (i) increasing the Commitment of one or more Banks which
have agreed to such increase in writing pursuant to the procedures described
below (it being understood that no Bank has any obligation to agree to such
increase) and/or (ii) adding one or more commercial banks or other Persons as a
party hereto (each an "Additional Bank") with a Commitment in an amount agreed
to by any such Additional Bank; provided that no Additional Bank shall be added
as a party hereto without the written consent of the Agent (which consent shall
not be unreasonably withheld) or if a Default or an Event of Default exists. Any
increase in the Aggregate Commitment pursuant to this clause (c) shall be
effective three Business Days (or such other reasonable period of time as may be
specified by the Agent) after the date on which the Agent has received (A) the
applicable increase letter in the form of Annex 1 to Exhibit H (in the case of
an increase in the Commitment of an existing Bank) or assumption letter in the
form of Annex 2 to Exhibit H (in the case of the addition of a commercial bank
or other Person as a new Bank), in each case signed by all applicable parties;
and (b) if the requested increase is to occur after the FMB Issue Date and
before the FMB Release Date and, after giving effect to such increase, the
Aggregate Commitment would exceed the face amount of all Bonds, additional Bonds
in an amount not less

                                       13
<PAGE>

than such excess together with such certificates, opinions of counsel and other
documents as the Agent may reasonably request in connection with the issuance
and delivery of such Bonds. The Agent shall promptly notify the Company and the
Banks of any increase in the amount of the Aggregate Commitment pursuant to this
clause (c) and of the Pro Rata Share of each Bank after giving effect thereto.
The parties hereto agree that, notwithstanding any other provision of this
Agreement, the Agent, the Company, each Additional Bank and each increasing
Bank, as applicable, may make arrangements satisfactory to such parties to cause
an Additional Bank or an increasing Bank to temporarily hold risk participations
in the outstanding Loans of the other Banks (rather than fund its Percentage of
all outstanding Loans concurrently with the applicable increase) with a view
toward minimizing breakage costs and transfers of funds in connection with any
increase in the Aggregate Commitment. The Company acknowledges that if, as a
result of an increase in the Aggregate Commitment that is not pro rata among the
existing Banks, any Eurodollar Rate Loan is prepaid or converted (in whole or in
part) on a day other than the last day of an Interest Period therefor, then such
prepayment or conversion shall be subject to the provisions of Section 4.4.

      2.6 Minimum Amount of Advances. Each Advance shall be in the minimum
amount of $10,000,000 (and in integral multiples of $1,000,000 if in excess
thereof); provided that any Floating Rate Advance may be in the amount of the
unused Aggregate Commitment (rounded down, if necessary, to an integral multiple
of $1,000,000).

      2.7 Optional Principal Payments. The Company may from time to time prepay,
without penalty or premium, all outstanding Floating Rate Advances or, in a
minimum aggregate amount of $10,000,000 or a higher integral multiple of
$1,000,000, any portion of the outstanding Floating Rate Advances upon one
Business Day's prior notice to the Agent. The Company may from time to time pay,
subject to the payment of any funding indemnification amounts required by
Section 4.4 but without penalty or premium, all outstanding Eurodollar Advances
or, in a minimum aggregate amount of $10,000,000 or a higher integral multiple
of $1,000,000, any portion of any outstanding Eurodollar Advance upon three
Business Days' prior notice to the Agent; provided that if after giving effect
to any such prepayment the principal amount of any Eurodollar Advance is less
than $10,000,000, such Eurodollar Advance shall automatically convert into a
Floating Rate Advance.

      2.8 Method of Selecting Types and Interest Periods for New Advances. The
Company shall select the Type of Advance and, in the case of each Eurodollar
Advance, the Interest Period applicable thereto from time to time. The Company
shall give the Agent irrevocable notice (a "Borrowing Notice") not later than
12:00 noon (New York time) on the Borrowing Date of each Floating Rate Advance
and not later than 12:00 noon (New York time) three Business Days before the
Borrowing Date for each Eurodollar Advance, specifying:

            (i) the Borrowing Date, which shall be a Business Day;

            (ii) the aggregate amount of such Advance;

            (iii) the Type of Advance selected; and

                                       14
<PAGE>

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

Promptly after receipt thereof, the Agent will notify each Bank of the contents
of each Borrowing Notice. Not later than 2:00 p.m. (New York time) on each
Borrowing Date, each Bank shall make available its Loan in funds immediately
available in New York to the Agent at its address specified pursuant to Section
14. To the extent funds are received from the Banks, the Agent will make such
funds available to the Company at the Agent's aforesaid address. No Bank's
obligation to make any Loan shall be affected by any other Bank's failure to
make any Loan.

      2.9 Conversion and Continuation of Outstanding Advances. Floating Rate
Advances shall continue as Floating Rate Advances unless and until such Floating
Rate Advances are converted into Eurodollar Advances pursuant to this Section
2.9 or are repaid in accordance with Section 2.2 or 2.7. Each Eurodollar Advance
shall continue as a Eurodollar Advance until the end of the then applicable
Interest Period therefor, at which time such Eurodollar Advance shall be
automatically converted into a Floating Rate Advance unless (x) such Eurodollar
Advance is or was repaid in accordance with Section 2.2 or 2.7 or (y) the
Company shall have given the Agent a Conversion/Continuation Notice (as defined
below) requesting that, at the end of such Interest Period, such Eurodollar
Advance continue as a Eurodollar Advance for the same or another Interest
Period. Subject to the terms of Section 2.6, the Company may elect from time to
time to convert all or any part of a Floating Rate Advance into a Eurodollar
Advance. The Company shall give the Agent irrevocable notice (a
"Conversion/Continuation Notice") of each conversion of a Floating Rate Advance
into a Eurodollar Advance or continuation of a Eurodollar Advance not later than
12:00 noon (New York time) at least three Business Days prior to the date of the
requested conversion or continuation, specifying:

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

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

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

provided that no Advance may be continued as, or converted into, a Eurodollar
Advance if (x) such continuation or conversion would violate any provision of
this Agreement or (y) a Default or Event of Default exists.

      2.10 Interest Rates, Interest Payment Dates. (a) Subject to Section 2.11,
each Advance shall bear interest as follows:

            (i) at any time such Advance is a Floating Rate Advance, at a rate
      per annum equal to the Floating Rate from time to time in effect; and

                                       15
<PAGE>

            (ii) at any time such Advance is a Eurodollar Advance, at a rate per
      annum equal to the Eurodollar Rate for each applicable Interest Period.

Changes in the rate of interest on that portion or any Advance maintained as a
Floating Rate Advance will take effect simultaneously with each change in the
Floating Rate.

      (b) Interest accrued on each Floating Rate Advance shall be payable on
each Payment Date and on the Revolving Termination Date (or, if the Company
exercises the Term Out Option, on the Final Maturity Date). Interest accrued on
each Eurodollar Advance shall be payable on the last day of its applicable
Interest Period, on any date on which such Eurodollar Advance is prepaid and on
the Revolving Termination Date (or, if the Company exercises the Term Out
Option, on the Final Maturity Date). Interest accrued on each Eurodollar Advance
having an Interest Period longer than three months shall also be payable on the
last day of each three-month interval during such Interest Period. Interest on
Eurodollar Advances and interest on Floating Rate Advances based on the Federal
Funds Effective Rate shall be calculated for actual days elapsed on the basis of
a 360-day year. Interest on Floating Rate Advances based on the Prime Rate shall
be calculated for actual days elapsed on the basis of a 365- or 366-day year, as
appropriate. Interest on each Advance shall accrue from and including the date
such Advance is made to but excluding the date payment thereof is received in
accordance with Section 2.12. If any payment of principal of or interest on an
Advance shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day (unless, in the case of a
Eurodollar Advance, such next succeeding Business Day falls in a new calendar
month, in which case such payment shall be due on the immediately preceding
Business Day) and, in the case of a principal payment, such extension of time
shall be included in computing interest in connection with such payment.

      2.11 Rate after Maturity. Any Advance not paid by the Company at maturity,
whether by acceleration or otherwise, shall bear interest until paid in full at
a rate per annum equal to the higher of (i) the rate otherwise applicable
thereto plus 1% or (ii) the Floating Rate plus 1%.

      2.12 Method of Payment. All payments of principal, interest and fees
hereunder shall be made in immediately available funds to the Agent at its
address specified on Schedule 3 (or at any other Lending Installation of the
Agent specified in writing by the Agent to the Company) not later than 1:00 p.m.
(New York time) on the date when due and shall be applied ratably by the Agent
among the Banks. Funds received after such time shall be deemed received on the
following Business Day unless the Agent shall have received from, or on behalf
of, the Company a Federal Reserve reference number with respect to such payment
before 4:00 p.m. (New York time) on the date of such payment. Each payment
delivered to the Agent for the account of any Bank shall be delivered promptly
by the Agent in the same type of funds received by the Agent to such Bank at the
address specified for such Bank in its Administrative Questionnaire or at any
Lending Installation specified in a notice received by the Agent from such Bank.
The Agent is hereby authorized to charge the account of the Company maintained
with Barclays, if any, for each payment of principal, interest and fees as such
payment becomes due hereunder.

      2.13 Bonds; Record-keeping; Telephonic Notices.

                                       16
<PAGE>

      (a) Beginning on the FMB Issue Date and continuing thereafter until the
FMB Release Date, the obligation of the Company to repay the Obligations shall
be evidenced by one or more Bonds. After the FMB Release Date, the Company
shall, at the request of any Bank deliver to such Bank a promissory note in form
and substance reasonably satisfactory to the Company, the Agent and such Bank.

      (b) Each Bank shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Company to such Bank
resulting from each Loan made by such Bank from time to time, including the
amounts of principal and interest payable and paid to such Bank from time to
time hereunder.

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

      (d) The entries maintained in the accounts maintained pursuant to clauses
(b) and (c) above shall be prima facie evidence of the existence and amounts of
the Obligations therein recorded; provided that the failure of the Agent or any
Bank to maintain such accounts or any error therein shall not in any manner
affect the obligation of the Company to repay the Obligations in accordance with
their terms.

      (e) The Company hereby authorizes the Banks and the Agent to make Advances
based on telephonic notices made by any person or persons the Agent or any Bank
in good faith believes to be acting on behalf of the Company. The Company agrees
to deliver promptly to the Agent a written confirmation of each telephonic
notice signed by a Designated Officer. If the written confirmation differs in
any material respect from the action taken by the Agent and the Banks, the
records of the Agent and the Banks shall govern absent manifest error.

      2.14 Lending Installations. Subject to the provisions of Section 4.6, each
Bank may book its Loans at any Lending Installation selected by such Bank and
may change its Lending Installation from time to time. All terms of this
Agreement shall apply to any such Lending Installation and the Loans shall be
deemed held by the applicable Bank for the benefit of such Lending Installation.
Each Bank may, by written or facsimile notice to the Company, designate a
Lending Installation through which Loans will be made by it and for whose
account payments on the Loans are to be made.

      2.15 Non-Receipt of Funds by the Agent. Unless a Bank or the Company, as
the case may be, notifies the Agent prior to the date on which it is scheduled
to make payment to the Agent of (i) in the case of a Bank, the proceeds of a
Loan or (ii) in the case of the Company, a payment of principal, interest or
fees to the Agent for the account of the Banks, that it does not intend to make
such payment, the Agent may assume that such payment has been made. The Agent
may, but shall not be obligated to, make the amount of such payment available to
the intended recipient in reliance upon such assumption. If such Bank or the
Company, as the case may be, has not in fact made such payment to the Agent, the
recipient of such payment shall, on

                                       17
<PAGE>

demand by the Agent, repay to the Agent the amount so made available together
with interest thereon in respect of each day during the period commencing on the
date such amount was so made available by the Agent until the date the Agent
recovers such amount at a rate per annum equal to (i) in the case of payment by
a Bank, the Federal Funds Rate for such day or (ii) in the case of payment by
the Company, the interest rate applicable to the relevant Loan.

                                   ARTICLE III
                                    SECURITY

      3.1 Mortgage and Security Agreement. Prior to the FMB Issue Date, the
Obligations shall be secured, pursuant to the Mortgage and Security Agreement,
by a second lien on the collateral securing the Company's First Mortgage Bonds
(excluding (a) surplus land at the Company's Ludington pumped storage plant and
(b) the Palisades nuclear power plant property that the Company proposes to sell
that also includes a parcel of land located at the Company's Big Rock Point site
where spent nuclear fuel is stored (the "Palisades Property"); provided that if
the Company determines that it will not proceed with the sale of all or
substantially all of the Palisades Property, or the Company has not entered into
a contract for the sale of such property by December 31, 2006, then the Company
will promptly grant a second lien on such property to secure the Obligations).

      3.2 First Mortgage Bonds. Within 60 days after the date on which the
Company has capacity (in addition to the $300,000,000 of capacity existing on
the date hereof) to issue First Mortgage Bonds under the Indenture in an amount
at least equal to the Aggregate Commitment, the Company shall issue First
Mortgage Bonds to the Agent pursuant to the Bond Delivery Agreement and a
Supplemental Indenture (the date of such issuance, the "FMB Issue Date"). Upon
the issuance of such First Mortgage Bonds, the Agent shall release the second
lien securing the Obligations referred to in Section 3.1.

      3.3 Release of Collateral. So long as the Obligations are secured by the
second lien referred to in Section 3.1, upon the request of the Company, the
Agent will promptly execute a release of such lien on any collateral that has
been contracted to be sold or otherwise disposed of by the Company if the
Indenture Trustee has released the lien on such property securing the First
Mortgage Bonds; provided that if an Acceleration (as defined in the Mortgage and
Security Agreement) has occurred, the Agent shall not be obligated to release
such lien unless it has received satisfactory evidence that the net proceeds of
such disposition will be applied to repay (a) First Mortgage Bonds, (b) the
Obligations or (c) ratably to the Obligations and to Debt of the type referred
to in the proviso to Section 7.1(p). Any such request shall be accompanied by a
signed copy of the release by the Indenture Trustee and a form of release in
recordable form for the Agent to execute. Upon receipt of such documents,
subject to the proviso to the first sentence of this Section 3.3, the Agent
shall forthwith execute such form of release without any further documentation
being required.

                                   ARTICLE IV
                             CHANGE IN CIRCUMSTANCES

      4.1 Yield Protection.

                                       18
<PAGE>

      (a) If any change in law or any governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law), or any
interpretation thereof by any agency or authority having jurisdiction over any
Bank,

            (i) subjects any Bank or any applicable Lending Installation to any
      increased tax, duty, charge or withholding on or from payments due from
      the Company (excluding taxation measured by or attributable to the overall
      net income of such Bank or such applicable Lending Installation, whether
      overall or in any geographic area), or changes the rate of taxation of
      payments to any Bank in respect of its Loans or other amounts due it
      hereunder, or

            (ii) imposes or increases or deems applicable any reserve,
      assessment, insurance charge, special deposit or similar requirement
      against assets of, deposits with or for the account of, or credit extended
      by any Bank or any applicable Lending Installation (including any reserve
      costs under Regulation D with respect to Eurocurrency liabilities (as
      defined in Regulation D)), or

            (iii) imposes any other condition the result of which is to increase
      the cost to any Bank or any applicable Lending Installation of making,
      funding or maintaining Loans, or reduces any amount receivable by any Bank
      or any applicable Lending Installation in connection with Loans or
      requires any Bank or any applicable Lending Installation to make any
      payment calculated by reference to its Loans or interest received by it,
      by an amount deemed material by such Bank, or

            (iv) affects the amount of capital required or expected to be
      maintained by any Bank or any applicable Lending Installation or any
      corporation controlling any Bank and such Bank determines the amount of
      capital required is increased by or based upon the existence of this
      Agreement or its obligation to make Loans hereunder or of commitments of
      this type,

then, upon presentation by such Bank to the Company of a certificate (as
referred to in the immediately succeeding sentence of this Section 4.1) setting
forth the basis for such determination and the additional amounts reasonably
determined by such Bank for the period of up to 90 days prior to the date on
which such certificate is delivered to the Company and the Agent, to be
sufficient to compensate such Bank in light of such circumstances, the Company
shall within 30 days of such delivery of such certificate pay to the Agent for
the account of such Bank the specified amounts set forth on such certificate.
The affected Bank shall deliver to the Company and the Agent a certificate
setting forth the basis of the claim and specifying in reasonable detail the
calculation of such increased expense, which certificate shall be prima facie
evidence as to such increase and such amounts. An affected Bank may deliver more
than one certificate to the Company during the term of this Agreement. In making
the determinations contemplated by the above-referenced certificate, any Bank
may make such reasonable estimates, assumptions, allocations and the like that
such Bank in good faith determines to be appropriate, and such Bank's selection
thereof in accordance with this Section 4.1 shall be conclusive and binding on
the Company, absent manifest error.

                                       19
<PAGE>

      (b) No Bank shall be entitled to demand compensation or be compensated
hereunder to the extent that such compensation relates to any period of time
more than 90 days prior to the date upon which such Bank first notified the
Company of the occurrence of the event entitling such Bank to such compensation
(unless, and to the extent, that any such compensation so demanded shall relate
to the retroactive application of any event so notified to the Company).

      4.2 Replacement Bank.

      (a) If any Bank shall make a demand for payment under Section 4.1, then
within 30 days after such demand, the Company may, with the approval of the
Agent (which approval shall not be unreasonably withheld) and provided that no
Default or Event of Default shall then have occurred and be continuing, demand
that such Bank assign to one or more financial institutions designated by the
Company and approved by the Agent all (but not less than all) of such Bank's
Commitment and Loans within the period ending on the later of such 30th day and
the last day of the longest of the then current Interest Periods. Any such
assignment shall be consummated on terms satisfactory to the assigning Bank;
provided that such Bank's consent to such assignment shall not be unreasonably
withheld.

      (b) If the Company shall elect to replace a Bank pursuant to clause (a)
above, the Company shall prepay the outstanding Loans of such Bank, and the
financial institution or institutions selected by the Company shall replace such
Bank as a Bank hereunder pursuant to an instrument satisfactory to the Company,
the Agent and the Bank being replaced by making Loans to the Company in the
amount of the outstanding Loans of such assigning Bank and assuming all the same
rights and responsibilities hereunder as such assigning Bank and having the same
Commitment as such assigning Bank.

      4.3 Availability of Eurodollar Rate Loans. If

      (a) any Bank determines that maintenance of a Eurodollar Rate Loan at a
suitable Lending Installation would violate any applicable law, rule, regulation
or directive, whether or not having the force of law, or

      (b) the Majority Banks determine that (i) deposits of a type and maturity
appropriate to match fund Eurodollar Rate Loans are not available or (ii) the
Base Eurodollar Rate does not accurately reflect the cost of making or
maintaining a Eurodollar Rate Loan,

then the Agent shall suspend the availability of Eurodollar Rate Loans and, in
the case of clause (a), require any outstanding Eurodollar Rate Loans to be
converted to Floating Rate Loans on such date as is required by the applicable
law, rule, regulation or directive.

      4.4 Funding Indemnification. If any payment of a Eurodollar Rate Loan
occurs on a date which is not the last day of an applicable Interest Period,
whether because of prepayment or otherwise, or a Eurodollar Rate Loan is not
made on the date specified by the Company for any reason other than default by
the Banks, the Company will indemnify each Bank for any loss or cost (but not
lost profits) incurred by it resulting therefrom, including any loss or cost in
liquidating or employing deposits acquired to fund or maintain such Eurodollar
Rate Loan;

                                       20
<PAGE>

provided that the Company shall not be liable for any of the foregoing to the
extent they arise because of acceleration by any Bank.

      4.5 Taxes.

      (a) All payments by the Company to or for the account of any Bank or the
Agent hereunder or under any Bond shall be made free and clear of and without
deduction for any and all Taxes. If the Company shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder to any Bank or
the Agent, (i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 4.5) such Bank or the Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Company shall make such deductions, (iii) the
Company shall pay the full amount deducted to the relevant authority in
accordance with applicable law and (iv) the Company shall furnish to the Agent
the original copy of a receipt evidencing payment thereof within 30 days after
such payment is made.

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

      (c) The Company hereby agrees to indemnify the Agent and each Bank for the
full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed
on amounts payable under this Section 4.5) paid by the Agent or such Bank and
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto. Payments due under this indemnification shall be made
within 30 days of the date the Agent or such Bank makes demand therefor pursuant
to Section 4.6.

      (d) Each Bank that is not incorporated under the laws of the United States
of America or a state thereof (each a "Non-U.S. Bank") agrees that it will, not
more than ten Business Days after the date hereof, or, if later, not more than
ten Business Days after becoming a Bank hereunder, (i) deliver to each of the
Company and the Agent two duly completed copies of United States Internal
Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Bank
is entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes, and (ii) deliver to each
of the Company and the Agent a United States Internal Revenue Form W-8 or W-9,
as the case may be, and certify that it is entitled to an exemption from United
States backup withholding tax. Each Non-U.S. Bank further undertakes to deliver
to each of the Company and the Agent (x) renewals or additional copies of such
form (or any successor form) on or before the date that such form expires or
becomes obsolete, and (y) after the occurrence of any event requiring a change
in the most recent forms so delivered by it, such additional forms or amendments
thereto as may be reasonably requested by the Company or the Agent. All forms or
amendments described in the preceding sentence shall certify that such Bank is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes, unless an event
(including any change in treaty, law or regulation) has occurred prior to the
date on

                                       21
<PAGE>

which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Bank from duly completing
and delivering any such form or amendment with respect to it and such Bank
advises the Company and the Agent that it is not capable of receiving payments
without any deduction or withholding of United States federal income tax.

      (e) For any period during which a Non-U.S. Bank has failed to provide the
Company with an appropriate form pursuant to clause (d), above (unless such
failure is due to a change in treaty, law or regulation, or any change in the
interpretation or administration thereof by any governmental authority,
occurring subsequent to the date on which a form originally was required to be
provided), such Non-U.S. Bank shall not be entitled to indemnification under
this Section 4.5 with respect to Taxes imposed by the United States; provided
that, should a Non-U.S. Bank which is otherwise exempt from or subject to a
reduced rate of withholding tax become subject to Taxes because of its failure
to deliver a form required under clause (d) above, the Company shall take such
steps as such Non-U.S. Bank shall reasonably request to assist such Non-U.S.
Bank to recover such Taxes.

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

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

      4.6 Bank Certificates, Survival of Indemnity. To the extent reasonably
possible, each Bank shall designate an alternate Lending Installation with
respect to Eurodollar Rate Loans to reduce any liability of the Company to such
Bank under Section 4.1 or to avoid the unavailability of Eurodollar Rate Loan
under Section 4.3, so long as such designation is not disadvantageous to such
Bank. A certificate of such Bank as to the amount due under Section 4.1, 4.4 or
4.5 shall be final, conclusive and binding on the Company in the absence of
manifest error. Determination of amounts payable under such Sections in
connection with a Eurodollar Rate Loan shall be calculated as though each Bank
funded each Eurodollar Rate Loan through the purchase of a deposit of the type
and maturity corresponding to the deposit used as a reference in determining

                                       22
<PAGE>

the Base Eurodollar Rate applicable to such Loan whether in fact that is the
case or not. Unless otherwise provided herein, the amount specified in any
certificate shall be payable on demand after receipt by the Company of such
certificate. The obligations of the Company under Sections 4.1, 4.4 and 4.5
shall survive payment of the Obligations and termination of this Agreement;
provided that no Bank shall be entitled to compensation to the extent that such
compensation relates to any period of time more than 90 days after the
termination of this Agreement.

                                   ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

      The Company hereby represents and warrants that:

      5.1 Incorporation and Good Standing. The Company is duly incorporated,
validly existing and in good standing under the laws of the State of Michigan.

      5.2 Corporate Power and Authority: No Conflicts. The execution, delivery
and performance by the Company of the Credit Documents are within the Company's
corporate powers, have been duly authorized by all necessary corporate action
and do not (i) violate the Company's charter, bylaws or any applicable law, or
(ii) breach or result in an event of default under any indenture or material
agreement, and do not result in or require the creation of any Lien upon or with
respect to any of its properties (except the Lien of the Indenture securing the
Bonds).

      5.3 Governmental Approvals. No authorization or approval or other action

                                       32

and the Obligations shall automatically become due and payable without notice,
presentment, demand, protest or other formalities of any kind, all of which are
hereby expressly waived by the Company.

                                   ARTICLE X
                        WAIVERS, AMENDMENTS AND REMEDIES

      10.1 Amendments. Subject to the provisions of this Article X, the Majority
Banks (or the Agent with the consent in writing of the Majority Banks) and the
Company may enter into written agreements supplemental hereto for the purpose of
adding or modifying any provisions to the Credit Documents or changing in any
manner the rights of the Banks or the Company hereunder or waiving any Event of
Default hereunder; provided that no such supplemental agreement shall, without
the consent of all of the Banks:

      (a) Extend the maturity of any Loan or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon or
fees thereon.

      (b) Modify the percentage specified in the definition of Majority Banks.

      (c) Extend the Revolving Termination Date or the Final Maturity Date or
increase the amount of the Commitment of any Bank hereunder or permit the
Company to assign its rights under this Agreement.

      (d) Amend Section 6.10, this Section 10.1 or Section 12.11.

      (e) Make any change in an express right in this Agreement of a single Bank
to give its consent, make a request or give a notice.

      (f) (i) Prior to the FMB Issue Date, release all or substantially all of
the collateral described in the Mortgage and Security Agreement or (ii) on or
after the FMB Issue Date, authorize the Agent to vote in favor of the release of
all or substantially all of the collateral securing the Bonds.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent.

      10.2 Preservation of Rights. No delay or omission of the Banks or the
Agent to exercise any right under the Credit Documents shall impair such right
or be construed to be a waiver of any Default or Event of Default or an
acquiescence therein, and the making of an Advance notwithstanding the existence
of a Default or Event of Default or the inability of the Company to satisfy the
conditions precedent to such Advance shall not constitute any waiver or
acquiescence. Any single or partial exercise of any such right shall not
preclude other or further exercise thereof or the exercise of any other right,
and no waiver, amendment or other variation of the terms, conditions or
provisions of the Credit Documents whatsoever shall be valid unless in writing
signed by the Banks required pursuant to Section 10.1, and then only to the
extent in such writing specifically set forth. All remedies contained in the
Credit Documents or by law

                                       33
<PAGE>

afforded shall be cumulative and all shall be available to the Agent and the
Banks until the Obligations have been paid in full.

representation and warranty (x) regarding no Material Adverse Change set forth

Advance.

                                  ARTICLE XII
                               GENERAL PROVISIONS

      12.1 Successors and Assigns. (a) The terms and provisions of the Credit
Documents shall be binding upon and inure to the benefit of the Company and the
Banks and their respective successors and assigns, except that the Company shall
not have the right to assign its rights under the Credit Documents. Any Bank may
sell participations in all or a portion of its rights and obligations under this
Agreement pursuant to clause (b) below and any Bank may assign all or any part
of its rights and obligations under this Agreement pursuant to clause (c) below.

                                       35
<PAGE>

      (b) Any Bank may sell participations to one or more banks or other
entities (each a "Participant") in all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment
and its Loans); provided that (i) such Bank's obligations under this Agreement
(including its Commitment to the Company hereunder) shall remain unchanged, (ii)
such Bank shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) such Bank shall remain the holder of its
Loans for all purposes of this Agreement and (iv) the Company shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement. Each Bank shall retain the sole right to
approve, without the consent of any Participant, any amendment, modification or
waiver of any provision of the Credit Documents other than any amendment,
modification or waiver with respect to any Loan or Commitment in which such
Participant has an interest which would require consent of all of the Banks
pursuant to the terms of Section 10.1 or of any other Credit Document. The
Company agrees that each Participant shall be deemed to have the right of setoff
provided in Section 12.10 in respect of its participating interest in amounts
owing under the Credit Documents to the same extent as if the amount of its
participating interest were owing directly to it as a Bank under the Credit
Documents; provided that each Bank shall retain the right of setoff provided in
Section 12.10 with respect to the amount of participating interests sold to each
Participant. The Banks agree to share with each Participant, and each
Participant, by exercising the right of setoff provided in Section 12.10, agrees
to share with each Bank, any amount received pursuant to the exercise of its
right of setoff, such amounts to be shared in accordance with Section 12.10 as
if each Participant were a Bank. The Company further agrees that each
Participant shall be entitled to the benefits of Sections 4.1, 4.3, 4.4 and 4.5
to the same extent as if it were a Bank and had acquired its interest by
assignment pursuant to Section 12.1(c); provided that (i) a Participant shall
not be entitled to receive any greater payment under Section 4.1, 4.3, 4.4 or
4.5 than the Bank that sold the participating interest to such Participant would
have received had it retained such interest for its own account, unless the sale
of such interest to such Participant is made with the prior written consent of
the Company, and (ii) any Participant not incorporated under the laws of the
United States of America or any State thereof agrees to comply with the
provisions of Section 4.5 to the same extent as if it were a Bank.

      (c) Any Bank may, in the ordinary course of its business and in accordance
with applicable law, at any time assign to one or more financial institutions or
other Persons all or any part of its rights and obligations under this
Agreement; provided that (i) unless such assignment is to another Bank, an
affiliate of such assigning Bank or any direct or indirect contractual
counterparty in any swap agreement relating to the Loans to the extent required
in connection with the settlement of such Bank's obligations pursuant thereto,
such Bank has received the Agent's and, so long as no Event of Default exists,
the Company's prior written consent to such assignment, which consent shall not
be unreasonably withheld or delayed, and (ii) the minimum principal amount of
any such assignment (other than assignments to a Federal Reserve Bank, to
another Bank, to an affiliate of such assigning Bank or to any direct or
indirect contractual counterparty in any swap agreement relating to the Loans to
the extent required in connection with the settlement of such Bank's obligations
pursuant thereto) shall be $5,000,000 (or such lesser amount consented to by the
Agent and, so long as no Event of Default shall be continuing, the Company),
which consents shall not be unreasonably withheld or delayed; provided that
after

                                       36
<PAGE>

giving effect to such assignment the assigning Bank shall have a Commitment of
not less than $5,000,000 (unless otherwise consented to by the Agent and, so
long as no Event of Default shall be continuing, the Company). Notwithstanding
the foregoing sentence, (x) any Bank may at any time, without the consent of the
Company or the Agent, assign all or any portion of its rights under this
Agreement to a Federal Reserve Bank; provided that no such assignment shall
release the transferor Bank from its obligations hereunder; and (y) no
assignment by a Bank shall release such Bank from its obligations hereunder
unless (I) the Agent and, so long as no Event of Default exists, the Company
have approved such assignment or (II) the creditworthiness of such affiliate (as
determined in accordance with customary standards of the banking industry) is no
less than that of the assigning Bank.

      (d) Any Bank may, in connection with any sale or participation or proposed
sale or participation pursuant to this Section 12.1, disclose to the purchaser
or participant or proposed purchaser or participant any information relating to
the Company furnished to such Bank by or on behalf of the Company; provided that
prior to any such disclosure of non-public information, the purchaser or
participant or proposed purchaser or participant (which purchaser or participant
is not an affiliate of a Bank) shall agree to preserve the confidentiality of
any confidential information (except any such disclosure as may be required by
law or regulatory process) relating to the Company received by it from such
Bank.

      (e) Assignments under this Section 12.1 shall be made pursuant to an
agreement (an "Assignment Agreement") substantially in the form of Exhibit D
hereto or in such other form as may be agreed to by the parties thereto and
shall not be effective until a $3,500 fee has been paid to the Agent by the
assignee, which fee shall cover the cost of processing such assignment; provided
that such fee shall not be incurred in the event of an assignment by any Bank of
all or a portion of its rights under this Agreement to (i) a Federal Reserve
Bank or (ii) a Bank or an affiliate of the assigning Bank or (iii) to any direct
or indirect contractual counterparties in swap agreements relating to the Loans
to the extent required in connection with the settlement of any Bank's
obligations pursuant thereto.

      12.2 Survival of Representations. All representations and warranties of
the Company contained in this Agreement shall survive the making of the Advances
herein contemplated.

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

      12.4 Taxes. Any taxes (excluding income taxes) payable or ruled payable by
any Federal or State authority in respect of the execution of the Credit
Documents shall be paid by the Company, together with interest and penalties, if
any.

      12.5 Choice of Law. THE CREDIT DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE
WITH THE INTERNAL LAWS (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW
OF NEW YORK, BUT OTHERWISE WITHOUT REGARD TO THE LAW OF CONFLICTS) OF THE STATE
OF NEW YORK, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS. THE
COMPANY

                                       37
<PAGE>

HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED
STATES FEDERAL OR NEW YORK STATE COURT SITTING IN NEW YORK, NEW YORK IN ANY
ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT AND THE
COMPANY HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION
OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT. THE COMPANY HEREBY
WAIVES ANY RIGHT TO A JURY TRIAL IN ANY ACTION OR ARISING HEREUNDER OR UNDER ANY
CREDIT DOCUMENT.

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

      12.7 Entire Agreement. The Credit Documents embody the entire agreement
and understanding between the Company, the Agent and the Banks and supersede all
prior agreements and understandings between the Company, the Agent and the Banks
relating to the subject matter thereof (other than those contained in the any
fee letter, which shall survive and remain in full force and effect during the
term of this Agreement).

      12.8 Expenses; Indemnification. The Company shall reimburse the Agent and
each Arranger for (a) any reasonable costs, internal charges and out-of-pocket
expenses (including reasonable attorneys' fees and time charges of attorneys for
the Agent) paid or incurred by the Agent or such Arranger in connection with the
preparation, review, execution, delivery, syndication, distribution (including
via the internet), amendment and modification of the Credit Documents and (b)
any reasonable costs, internal charges and out-of-pocket expenses (including
reasonable attorneys' fees and time charges of attorneys for the Agent) paid or
incurred by the Agent or such Arranger on its own behalf or on behalf of any
Bank and, on or after the date upon which an Event of Default specified in
Section 9.1(a) or 9.1(e) has occurred and is continuing, each Bank, in
connection with the collection and enforcement of the Credit Documents. The
Company further agrees to indemnify the Agent, each Arranger, each Bank and
their respective Affiliates, and the directors, officers, employees and agents
of the foregoing (all of the foregoing, the "Indemnified Persons), against all
losses, claims, damages, penalties, judgments, liabilities and reasonable
expenses (including all reasonable expenses of litigation or preparation
therefor whether or not an Indemnified Person is a party thereto) which any of
them may pay or incur arising out of or relating to this Agreement, the other
Credit Documents, the transactions contemplated hereby, the direct or indirect
application or proposed application of the proceeds of any Advance hereunder,
any actual or alleged presence or release of any Hazardous Substance on or from
any property owned or operated by the Company or any Subsidiary or any
Environmental Liability related in any way to the Company or any Subsidiary;
provided that the Company shall not be liable to any Indemnified Person for any
of the foregoing to the extent they arise from the gross negligence or willful
misconduct of such Indemnified Person. Without limiting the foregoing, the
Company shall pay any civil penalty or fine assessed by the Office of Foreign
Assets Control against any Indemnified Person, and all reasonable costs and
expenses (including reasonable fees and expenses of counsel to such Indemnified
Person) incurred in connection with defense thereof, as a result of any breach
or inaccuracy of the representation

                                       38
<PAGE>

made in Section 5.14. The obligations of the Company under this Section shall
survive the termination of this Agreement.

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

      12.10 Setoff. In addition to, and without limitation of, any rights of the
Banks under applicable law, if the Company becomes insolvent, however evidenced,
or any Default or Event of Default occurs, any indebtedness from any Bank or any
of its Affiliates to the Company (including all account balances, whether
provisional or final and whether or not collected or available) may be offset
and applied toward the payment of the Obligations owing to such Bank or such
Affiliate, whether or not the Obligations, or any part hereof, shall then be
due. The Company agrees that any purchaser or participant under Section 12.1
may, to the fullest extent permitted by law, exercise all its rights of payment
with respect to such purchase or participation as if it were the direct creditor
of the Company in the amount of such purchase or participation.

      12.11 Ratable Payments. If any Bank, whether by setoff or otherwise, has
payment made to it upon its Loans in a greater proportion than that received by
any other Bank, such Bank agrees, promptly upon demand, to purchase a portion of
the Loans held by the other Banks so that after such purchase each Bank will
hold its Pro Rata Share of all outstanding Loans. If any Bank, whether in
connection with setoff or amounts which might be subject to setoff or otherwise,
receives collateral or other protection for its Obligations or such amounts
which may be subject to setoff, such Bank agrees, promptly upon demand, to take
such action necessary such that all Banks share in the benefits of such
collateral ratably in proportion to their respective Pro Rata Share of the Total
Outstandings. In case any such payment is disturbed by legal process, or
otherwise, appropriate further adjustments shall be made.

      12.12 Nonliability. The relationship between the Company, on the one hand,
and the Banks, the Arrangers and the Agent, on the other hand, shall be solely
that of borrower and lender. None of the Agent, either Arranger or any Bank
shall have any fiduciary responsibilities to the Company. None of the Agent,
either Arranger or any Bank undertakes any responsibility to the Company to
review or inform the Company of any matter in connection with any phase of the
Company's business or operations. The Company shall rely entirely upon its own
judgment with respect to its business, and any review, inspection, supervision
or information supplied to the Company by the Banks is for the protection of the
Banks and neither the Company nor any third party is entitled to rely thereon.
The Company agrees that none of the Agent, either Arranger or any Bank shall
have liability to the Company (whether sounding in tort, contract or otherwise)
for losses suffered by the Company in connection with, arising out of, or in any
way related to, the transactions contemplated and the relationship established
by the Credit Documents, or any act, omission or event occurring in connection
therewith, unless it is determined in a final non-appealable judgment by a court
of competent jurisdiction that such losses resulted from the gross negligence or
willful misconduct of the party from which recovery is sought. None of the
Agent, either Arranger or any Bank shall have any liability with respect

                                       39
<PAGE>

to, and the Company hereby waives, releases and agrees not to sue for, any
special, indirect, consequential or punitive damages suffered by the Company in
connection with, arising out of, or in any way related to the Credit Documents
or the transactions contemplated thereby.

      12.13 Other Agents. The Banks identified on the signature pages of this
Agreement or otherwise herein, or in any amendment hereof or other document
related hereto, as being the "Syndication Agent", a "Co-Documentation Agent" or
a "Co-Managing Agent" (the "Other Agents") shall have no rights, powers,
obligations, liabilities, responsibilities or duties under this Agreement other
than those applicable to all Banks as such. Without limiting the foregoing, the
Other Agents shall not have or be deemed to have any fiduciary relationship with
any Bank. Each Bank acknowledges that it has not relied, and will not rely, on
the Other Agents in deciding to enter into this Agreement or in taking or
refraining from taking any action hereunder or pursuant hereto.

      12.14 USA Patriot Act. Each Bank hereby notifies the Company that pursuant
to requirements of the USA Patriot Act, such Bank is required to obtain, verify
and record information that identifies the Company, which information includes
the name and address of the Company and other information that will allow such
Bank to identify the Company in accordance with the USA Patriot Act.

      12.15 Platform.

      (a) The Company shall use its commercially reasonable best efforts to
transmit to the Agent all information, documents and other materials that it is
obligated to furnish to the Agent pursuant to this Agreement and the other
Credit Documents, including all notices, requests, financial statements,
financial and other reports, certificates and other information materials, but
excluding (i) any Borrowing Notice, Conversion/Continuation Notice or notice of
prepayment, (ii) any notice of a Default or an Event of Default or (iii) any
communication that is required to be delivered to satisfy any condition
precedent to the effectiveness of this Agreement and/or any Advance hereunder
(all such non-excluded communications, collectively, "Communications"), in an
electronic/soft medium in a format reasonably acceptable to the Agent to such
e-mail address as designated by the Agent from time to time. In addition, the
Company shall continue to provide Communications to the Agent or any Bank in the
manner specified in this Agreement but only to the extent requested by the Agent
or such Bank. Each Bank and the Company further agrees that the Agent may make
Communications available to the Banks by posting Communications on IntraLinks or
a substantially similar electronic transmission system (the "Platform");
provided, that upon written notice to the Agent and the Company, any Bank (such
bank, a "Declining Bank") may decline to receive Communications via the Platform
and shall direct the Company to provide, and the Company shall so provide, such
Communications to such Declining Bank by delivery to such Declining Bank's
address in accordance with Section 14.1. Subject to the conditions set forth in
the proviso in the immediately preceding sentence, nothing in this Section 12.15
shall prejudice the right of the Agent to make Communications available to the
Banks in any other manner specified herein.

      (b) Each Bank (other than a Declining Bank) agrees that e-mail notice to
it (at the address provided pursuant to the next sentence and deemed delivered
as provided in clause (c)

                                       40
<PAGE>

below) specifying that a Communication has been posted to the Platform shall
constitute effective delivery of such Communication to such Bank for purposes of
this Agreement. Each Bank (other than a Declining Bank) agrees (i) to notify the
Agent in writing (including by electronic communication) from time to time to
ensure that the Agent has on record an effective e-mail address for such Bank to
which the foregoing notice may be sent by electronic transmission and (ii) that
the foregoing notice may be sent to such e-mail address.

      (c) Each party hereto (other than a Declining Bank) agrees that any
electronic Communication referred to in this Section 12.15 shall be deemed
delivered upon the posting of a record of such Communication as "sent" in the
e-mail system of the sending party or, in the case of any such Communication to
the Agent, upon the posting of a record of such Communication as "received" in
the e-mail system of the Agent, provided that if such Communication is not so
received by a Person during the normal business hours of such Person, such
Communication shall be deemed delivered at the opening of business on the next
business day for such Person.

      (d) Each party hereto acknowledges that the distribution of material
through an electronic medium is not necessarily secure and there are
confidentiality and other risks associated with such distribution.

      (e) EACH PARTY HERETO FURTHER ACKNOWLEDGES AND AGREES THAT:

            (i) NONE OF THE AGENT OR ITS AFFILIATES OR ANY OF THEIR RESPECTIVE
      OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES
      (COLLECTIVELY, THE "AGENT PARTIES") WARRANTS THE ADEQUACY OF THE PLATFORM
      OR THE ACCURACY OR COMPLETENESS OF ANY COMMUNICATION, AND EACH AGENT PARTY
      EXPRESSLY DISCLAIMS LIABILITY FOR ERRORS OR OMISSIONS IN ANY
      COMMUNICATION; AND

            (ii) NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY,
      INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
      PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR
      OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH ANY
      COMMUNICATION OR THE PLATFORM.

      (f) This Section 12.15 shall terminate on the date that no Agent Party is
the Agent under this Agreement.

                                  ARTICLE XIII

by the Agent.

      13.3 General Immunity. Neither the Agent nor any of its directors,

fully protected in acting, or in refraining from acting, hereunder and under any
other Credit Document in accordance with written instructions signed by the
Majority Banks (or all of the Banks if required by Section 10.1), and such
instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Banks. The Banks hereby acknowledge that the Agent shall
be under no duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement or any other Credit Document unless
it shall be requested in writing to do so by the Majority Banks. The Agent shall
be fully justified in failing or refusing to take any action hereunder and under
any other Credit Document unless it shall first be indemnified to its
satisfaction by the Banks pro rata against any and all liability, cost and
expense that it may incur by reason of taking or continuing to take any such
action.

      13.6 Employment of Agents and Counsel. The Agent may execute any of its
duties as Agent hereunder by or through employees, agents and attorneys-in-fact
and shall not be answerable to the Banks, except as to money or securities
received by it or its authorized agents, for the default or misconduct of any
such agents or attorneys-in-fact selected by it with reasonable care. The Agent
shall be entitled to advice of counsel concerning all matters pertaining to the
agency hereby created and its duties hereunder.

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

      13.8 Agent's Reimbursement and Indemnification. The Banks agree to
reimburse and indemnify the Agent ratably in accordance with their respective
Pro Rata Shares (i) for any

                                       42
<PAGE>

amounts not reimbursed by the Company for which the Agent is entitled to
reimbursement by the Company under the Credit Documents, (ii) for any other
expenses reasonably incurred by the Agent on behalf of the Banks, in connection
with the preparation, execution, delivery, administration and enforcement of the
Credit Documents, and for which the Agent is not entitled to reimbursement by
the Company under the Credit Documents, and (iii) for any liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind and nature whatsoever which may be imposed
on, incurred by or asserted against the Agent in any way relating to or arising
out of this Agreement or any other document delivered in connection with this
Agreement or the transactions contemplated hereby or the enforcement of any of
the terms hereof or of any such other documents, and for which the Agent is not
entitled to reimbursement by the Company under the Credit Documents; provided
that no Bank shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of the Agent.

      13.9 Rights as a Bank. With respect to its Commitment and any Advance made
by it, the Agent shall have the same rights and powers hereunder as any Bank and
may exercise the same as though it were not the Agent, and the term "Bank" or
"Banks" shall, unless the context otherwise indicates, include Barclays in its
individual capacity. The Agent may accept deposits from, lend money to, and
generally engage in any kind of banking or trust business with the Company or
any Subsidiary as if it were not the Agent.

      13.10 Bank Credit Decision. (a) Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank and based on
the financial statements prepared by the Company and such other documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Bank also acknowledges that it will,
independently and without reliance upon the Agent or any other Bank and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement.

      (b) Without limiting clause (a) above, each Bank acknowledges and agrees
that neither such Bank nor any of its Affiliates, participants or assignees may
rely on the Agent to carry out such Bank's or other Person's customer
identification program, or other obligations required or imposed under or
pursuant to the USA Patriot Act or the regulations thereunder, including the
regulations contained in 31 C.F.R. 103.121 (as amended or replaced, the "CIP
Regulations"), or any other applicable law, rule, regulation or order of any
governmental authority, including any program involving any of the following
items relating to or in connection with the Company or any of its Subsidiaries
or Affiliates or agents, the Credit Documents or the transactions contemplated
hereby: (i) any identity verification procedure; (ii) any recordkeeping; (iii)
any comparison with a government list; (iv) any customer notice or (v) any other
procedure required under the CIP Regulations or such other law, rule, regulation
or order.

      (c) Within 10 days after the date of this Agreement and at such other
times as are required under the USA Patriot Act, each Bank and each assignee and
participant that is not incorporated under the laws of the United States of
America or a state thereof (and is not excepted from the certification
requirement contained in Section 313 of the USA Patriot Act and

                                       43
<PAGE>

the applicable regulations because it is both (i) an affiliate of a depository
institution or foreign bank that maintains a physical presence in the United
States or foreign country and (ii) subject to supervision by a banking authority
regulating such affiliated depository institution or foreign bank) shall deliver
to the Agent a certification, or, if applicable, recertification, certifying
that such Bank is not a "shell" and certifying as to other matters as required
by Section 313 of the USA Patriot Act and the applicable regulations.

      13.11 Successor Agent. The Agent may resign at any time by giving written
notice thereof to the Banks and the Company, and the Agent may be removed at any
time with or without cause by written notice received by the Agent from the
Majority Banks. Upon any such resignation or removal, the Majority Banks shall
have the right to appoint, on behalf of the Banks, a successor Agent. If no
successor Agent shall have been so appointed by the Majority Banks and shall
have accepted such appointment within thirty days after the retiring Agent's
giving notice of resignation, then the retiring Agent may appoint, on behalf of
the Banks, a successor Agent. Such successor Agent shall be a commercial bank
having capital and retained earnings of at least $500,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions of this Article
XIII shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Agent hereunder.

      13.12 Agent and Arranger Fees. The Company agrees to pay to the Agent and
the Arrangers, for their respective accounts, such fees as may be agreed to
between or among any of such parties from time to time.

continued provisions shall for all purposes have the same effect as though fully
set forth at this place.

      This bond shall not be valid or become obligatory for any purpose unless

                               FIRST MORTGAGE BOND
                [200[ ]-[ ]] COLLATERAL SERIES (INTEREST BEARING)

      This bond is one of the bonds of a series designated as First Mortgage
Bonds, [200[ ]-[ ]] Collateral Series (Interest Bearing) (sometimes herein
referred to as the "[200[ ]-[ ]] Collateral Bonds") issued under and in
accordance with and secured by an Indenture dated as of September 1, 1945, given
by the Company (or its predecessor, Consumers Power Company, a Maine
corporation) to City Bank Farmers Trust Company (JPMorgan Chase Bank, N.A.,
successor) (hereinafter sometimes referred to as the "Trustee"), together with
indentures supplemental thereto, heretofore or hereafter executed, to which
indenture and indentures supplemental thereto (hereinafter referred to
collectively as the "Indenture") reference is hereby made for a description of
the property mortgaged and pledged, the nature and extent of the security and
the rights, duties and immunities thereunder of the Trustee and the rights of
the holders of said bonds and of the Trustee and of the Company in respect of
such security, and the limitations on such rights. By the terms of the
Indenture, the bonds to be secured thereby are issuable in series which may vary
as to date, amount, date of maturity, rate of interest and in other respects as
provided in the Indenture.

      The [200[ ]-[ ]] Collateral Bonds are to be issued and delivered to the
Agent in order to evidence and secure the obligation of the Company under the
Credit Agreement to make payments to the Banks under the Credit Agreement and to
provide the Banks the benefit of the lien of the Indenture with respect to the
[200[ ]-[ ]] Collateral Bonds.

      The obligation of the Company to make payments with respect to the
principal of [200[ ]-[ ]] Collateral Bonds shall be fully or partially, as the
case may be, satisfied and discharged to the extent that, at the time that any
such payment shall be due, the then due principal of the Loans included in the
Obligations shall have been fully or partially paid. Satisfaction of any
obligation to the extent that payment is made with respect to the Loans means
that if any payment is made on the principal of the Loans, a corresponding
payment obligation with respect to the principal of the [200[ ]-[ ]] Collateral
Bonds shall be deemed discharged in the same amount as the payment with respect
to the Loans discharges the outstanding obligation with respect to such Loans.
No such payment of principal shall reduce the principal amount of the [200[ ]-
[ ]] Collateral Bonds.

      The obligation of the Company to make payments with respect to the
interest on [200[ ]-[ ]] Collateral Bonds shall be fully or partially, as the
case may be, satisfied and discharged to the extent that, at the time that any
such payment shall be due, the then due interest and/or fees under the Credit
Agreement shall have been fully or partially paid. Satisfaction of any
obligation to the extent that payment is made with respect to the interest
and/or fees under the Credit Agreement means that if any payment is made on the
interest and/or fees under the Credit Agreement, a corresponding payment
obligation with respect to the interest on the [200[ ]-[ ]] Collateral Bonds
shall be deemed discharged in the same amount as the payment with respect to the
Loans discharges the outstanding obligation with respect to such Loans.

                                      A-7
<PAGE>

      The Trustee may at any time and all times conclusively assume that the
obligation of the Company to make payments with respect to the principal of and
interest on this bond, so far as such payments at the time have become due, has
been fully satisfied and discharged unless and until the Trustee shall have
received a written notice from the Agent stating (i) that timely payment of
principal and interest on the [200[ ]-[ ]] Collateral Bonds has not been made,
(ii) that the Company is in arrears as to the payments required to be made by it
to the Agent in connection with the Obligations pursuant to the Credit
Agreement, and (iii) the amount of the arrearage.

      If an Event of Default (as defined in the Credit Agreement) with respect
to the payment of the principal of the Loans shall have occurred, it shall be
deemed to be a default for purposes of Section 11.01 of the Indenture in the
payment of the principal of the [200[ ]-[ ]] Collateral Bonds equal to the
amount of such unpaid principal (but in no event in excess of the principal
amount of the [200[ ]-[ ]] Collateral Bonds). If an Event of Default (as defined
in the Credit Agreement) with respect to the payment of interest on the Loans or
any fees shall have occurred, it shall be deemed to be a default for purposes of
Section 11.01 of the Indenture in the payment of the interest on the [200[ ]-
[ ]] Collateral Bonds equal to the amount of such unpaid interest or fees.

      This bond is not redeemable except upon written demand of the Agent
following the occurrence of an Event of Default under the Credit Agreement and
the acceleration of the Obligations, as provided in Section 9.2 of the Credit
Agreement. This bond is not redeemable by the operation of the improvement fund
or the maintenance and replacement provisions of the Indenture or with the
proceeds of released property.

      In case of certain defaults as specified in the Indenture, the principal
of this bond may be declared or may become due and payable on the conditions, at
the time, in the manner and with the effect provided in the Indenture. The
holders of certain specified percentages of the bonds at the time outstanding,
including in certain cases specified percentages of bonds of particular series,
may in certain cases, to the extent and as provided in the Indenture, waive
certain defaults thereunder and the consequences of such defaults.

      The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than seventy-five per centum in
principal amount of the bonds (exclusive of bonds disqualified by reason of the
Company's interest therein) at the time outstanding, including, if more than one
series of bonds shall be at the time outstanding, not less than sixty per centum
in principal amount of each series affected, to effect, by an indenture
supplemental to the Indenture, modifications or alterations of the Indenture and
of the rights and obligations of the Company and the rights of the holders of
the bonds and coupons; provided, however, that no such modification or
alteration shall be made without the written approval or consent of the holder
hereof which will (a) extend the maturity of this bond or reduce the rate or
extend the time of payment of interest hereon or reduce the amount of the
principal hereof, or (b) permit the creation of any lien, not otherwise
permitted, prior to or on a parity with the lien of the Indenture, or (c) reduce
the percentage of the principal amount of the bonds the holders of which are
required to approve any such supplemental indenture.

                                      A-8
<PAGE>

      The Company reserves the right, without any consent, vote or other action
by holders of the [200[ ]-[ ]] Collateral Bonds or any other series created
after the Sixty-eighth Supplemental Indenture, to amend the Indenture to reduce
the percentage of the principal amount of bonds the holders of which are
required to approve any supplemental indenture (other than any supplemental
indenture which is subject to the proviso contained in the immediately preceding
sentence) (a) from not less than seventy-five per centum (including sixty per
centum of each series affected) to not less than a majority in principal amount
of the bonds at the time outstanding or (b) in case fewer than all series are
affected, not less than a majority in principal amount of the bonds of all
affected series, voting together.

      No recourse shall be had for the payment of the principal of or interest
on this bond, or for any claim based hereon, or otherwise in respect hereof or
of the Indenture, to or against any incorporator, stockholder, director or
officer, past, present or future, as such, of the Company, or of any predecessor
or successor company, either directly or through the Company, or such
predecessor or successor company, or otherwise, under any constitution or
statute or rule of law, or by the enforcement of any assessment or penalty, or
otherwise, all such liability of incorporators, stockholders, directors and
officers, as such, being waived and released by the holder and owner hereof by
the acceptance of this bond and being likewise waived and released by the terms
of the Indenture.

      This bond shall be exchangeable for other registered bonds of the same
series, in the manner and upon the conditions prescribed in the Indenture, upon
the surrender of such bonds at the Investor Services Department of the Company,
as transfer agent. However, notwithstanding the provisions of Section 2.05 of
the Indenture, no charge shall be made upon any registration of transfer or
exchange of bonds of said series other than for any tax or taxes or other
governmental charge required to be paid by the Company.

      The Agent shall surrender this bond to the Trustee when all of the
principal of and interest on the Loans arising under the Credit Agreement, and
all of the fees payable pursuant to the Credit Agreement with respect to the
Obligations shall have been duly paid, and the Credit Agreement shall have been
terminated.

      BUT IN TRUST, NEVERTHELESS, with power of sale for the equal and
proportionate benefit and security of the holders of all bonds now or hereafter
authenticated and delivered under and secured by the Indenture and interest
coupons appurtenant thereto, pursuant to the provisions of the Indenture and of
any supplemental indenture, and for the enforcement of the payment of said bonds
and coupons when payable and the performance of and compliance with the
covenants and conditions of the Indenture and of any supplemental indenture,
without any preference, distinction or priority as to lien or otherwise of any
bond or bonds over others by reason of the difference in time of the actual
authentication, delivery, issue, sale or negotiation thereof or for any other
reason whatsoever, except as otherwise expressly provided in the Indenture; and
so that each and every bond now or hereafter authenticated and delivered
thereunder shall have the same lien, and so that the principal of and premium,
if any, and interest on every such bond shall, subject to the terms thereof, be
equally and proportionately secured, as if it had been made, executed,
authenticated, delivered, sold and negotiated simultaneously with the execution
and delivery thereof.

      AND IT IS EXPRESSLY DECLARED by the Company that all bonds authenticated
and delivered under and secured by the Indenture, as supplemented and amended as
above set forth, are to be issued, authenticated and delivered, and all said
premises, property, franchises and rights hereby and by the Indenture and
indentures supplemental thereto conveyed, assigned, pledged or mortgaged, or
intended so to be, are to be dealt with and disposed of under, upon and subject
to the terms, conditions, stipulations, covenants, agreements, trusts, uses and
purposes expressed in the Indenture, as supplemented and amended as above set
forth, and the parties hereto mutually agree as follows:

      SECTION 1. There is hereby created a series of bonds (the "[200[ ]-[ ]]
Collateral Bonds") designated as hereinabove provided, which shall also bear the
descriptive title "First Mortgage Bond", and the forms thereof shall be
substantially as hereinbefore set forth (collectively, the "Sample Bond"). The
[200[ ]-[ ]] Collateral Bonds shall be issued in the aggregate principal amount
of $__________, shall mature on the Revolving Termination Date (as defined in
the Credit Agreement) or, if the Company exercises the Term Out Option (as
defined in the Credit Agreement), the Final Maturity Date (as defined in the
Credit Agreement) and shall be issued only as registered bonds without coupons
in denominations of $1,000 and any multiple thereof. The serial numbers of the
Collateral Bonds shall be such as may be approved by any officer of the Company,
the execution thereof by any such officer either manually or by facsimile
signature to be conclusive evidence of such approval. The Collateral Bonds are
to be issued to and registered in the name of the Agent under the Credit
Agreement (as defined in the Sample Bonds) to evidence and secure any and all
Obligations (as defined in the Credit Agreement) of the Company under the Credit
Agreement.

      The [200[ ]-[ ]] Collateral Bonds shall bear interest as set forth in the
Sample Bond. The principal of and the interest on said bonds shall be payable as
set forth in the Sample Bond.

      The obligation of the Company to make payments with respect to the
principal of [200[ ]-[ ]] Collateral Bonds shall be fully or partially, as the
case may be, satisfied and discharged to the extent that, at the time that any
such payment shall be due, the then due principal of the Loans included in the
Obligations shall have been fully or partially paid. Satisfaction of any

                                      A-11
<PAGE>

obligation to the extent that payment is made with respect to the Loans means
that if any payment is made on the principal of the Loans, a corresponding
payment obligation with respect to the principal of the [200[ ]-[ ]] Collateral
Bonds shall be deemed discharged in the same amount as the payment with respect
to the Loans discharges the outstanding obligation with respect to such Loans.
No such payment of principal shall reduce the principal amount of the [200[ ]-
[ ]] Collateral Bonds.

      The obligation of the Company to make payments with respect to interest on
[200[ ]-[ ]] Collateral Bonds shall be fully or partially, as the case may be,
satisfied and discharged to the extent that, at the time that any such payment
shall be due, the then due interest and/or fees under the Credit Agreement shall
have been fully or partially paid. Satisfaction of any obligation to the extent
that payment is made with respect to the interest and/or fees under the Credit
Agreement means that if any payment is made on the interest and/or fees under
the Credit Agreement, a corresponding payment obligation with respect to the
interest on the [200[ ]-[ ]] Collateral Bonds shall be deemed discharged in the
same amount as the payment with respect to the interest and/or fees discharges
the outstanding obligation with respect to such interest and/or fees.

      The Trustee may at any time and all times conclusively assume that the
obligation of the Company to make payments with respect to the principal of and
interest on the Collateral Bonds, so far as such payments at the time have
become due, has been fully satisfied and discharged unless and until the Trustee
shall have received a written notice from the Agent stating (i) that timely
payment of principal and interest on the [200[ ]-[ ]] Collateral Bonds has not
been made, (ii) that the Company is in arrears as to the payments required to be
made by it to the Agent pursuant to the Credit Agreement, and (iii) the amount
of the arrearage.

      The Collateral Bonds shall be exchangeable for other registered bonds of
the same series, in the manner and upon the conditions prescribed in the
Indenture, upon the surrender of such bonds at the Investor Services Department
of the Company, as transfer agent. However, notwithstanding the provisions of
Section 2.05 of the Indenture, no charge shall be made upon any registration of
transfer or exchange of bonds of said series other than for any tax or taxes or
other governmental charge required to be paid by the Company.

      SECTION 2. The Collateral Bonds are not redeemable by the operation of the
maintenance and replacement provisions of this Indenture or with the proceeds of
released property.

      SECTION 3. Upon the occurrence of an Event of Default under the Credit
Agreement and the acceleration of the Obligations, the Collateral Bonds shall be
redeemable in whole upon receipt by the Trustee of a written demand from the
Agent stating that there has occurred under the Credit Agreement both an Event
of Default and a declaration of acceleration of the Obligations and demanding
redemption of the Collateral Bonds (including a description of the amount of
principal, interest and fees which comprise such Obligations). The Company
waives any right it may have to prior notice of such redemption under the
Indenture. Upon surrender of the Collateral Bonds by the Agent to the Trustee,
the Collateral Bonds shall be redeemed at a redemption price equal to the
aggregate amount of the Obligations.

                                      A-12
<PAGE>

      SECTION 4. The Company reserves the right, without any consent, vote or
other action by the holder of the Collateral Bonds or of any subsequent series
of bonds issued under the Indenture, to make such amendments to the Indenture,
as supplemented, as shall be necessary in order to amend Section 17.02 to read
as follows:

            SECTION 17.02. With the consent of the holders of not less than a
      majority in principal amount of the bonds at the time outstanding or their
      attorneys-in-fact duly authorized, or, if fewer than all series are
      affected, not less than a majority in principal amount of the bonds at the
      time outstanding of each series the rights of the holders of which are
      affected, voting together, the Company, when authorized by a resolution,
      and the Trustee may from time to time and at any time enter into an
      indenture or indentures supplemental hereto for the purpose of adding any
      provisions to or changing in any manner or eliminating any of the
      provisions of this Indenture or of any supplemental indenture or modifying
      the rights and obligations of the Company and the rights of the holders of
      any of the bonds and coupons; provided, however, that no such supplemental
      indenture shall (1) extend the maturity of any of the bonds or reduce the
      rate or extend the time of payment of interest thereon, or reduce the
      amount of the principal thereof, or reduce any premium payable on the
      redemption thereof, without the consent of the holder of each bond so
      affected, or (2) permit the creation of any lien, not otherwise permitted,
      prior to or on a parity with the lien of this Indenture, without the
      consent of the holders of all the bonds then outstanding, or (3) reduce
      the aforesaid percentage of the principal amount of bonds the holders of
      which are required to approve any such supplemental indenture, without the
      consent of the holders of all the bonds then outstanding. For the purposes
      of this Section, bonds shall be deemed to be affected by a supplemental
      indenture if such supplemental indenture adversely affects or diminishes
      the rights of holders thereof against the Company or against its property.
      The Trustee may in its discretion determine whether or not, in accordance
      with the foregoing, bonds of any particular series would be affected by
      any supplemental indenture and any such determination shall be conclusive
      upon the holders of bonds of such series and all other series. Subject to
      the provisions of Sections 16.02 and 16.03 hereof, the Trustee shall not
      be liable for any determination made in good faith in connection herewith.

            Upon the written request of the Company, accompanied by a resolution
      authorizing the execution of any such supplemental indenture, and upon the
      filing with the Trustee of evidence of the consent of bondholders as
      aforesaid (the instrument or instruments evidencing such consent to be
      dated within one year of such request), the Trustee shall join with the
      Company in the execution of such supplemental indenture unless such
      supplemental indenture affects the Trustee's own rights, duties or
      immunities under this Indenture or otherwise, in which case the Trustee

                                      A-13
<PAGE>

      may in its discretion but shall not be obligated to enter into such
      supplemental indenture.

            It shall not be necessary for the consent of the bondholders under
      this Section to approve the particular form of any proposed supplemental
      indenture, but it shall be sufficient if such consent shall approve the
      substance thereof.

            The Company and the Trustee, if they so elect, and either before or
      after such consent has been obtained, may require the holder of any bond
      consenting to the execution of any such supplemental indenture to submit
      his bond to the Trustee or to ask such bank, banker or trust company as
      may be designated by the Trustee for the purpose, for the notation thereon
      of the fact that the holder of such bond has consented to the execution of
      such supplemental indenture, and in such case such notation, in form
      satisfactory to the Trustee, shall be made upon all bonds so submitted,
      and such bonds bearing such notation shall forthwith be returned to the
      persons entitled thereto.

            Prior to the execution by the Company and the Trustee of any
      supplemental indenture pursuant to the provisions of this Section, the
      Company shall publish a notice, setting forth in general terms the
      substance of such supplemental indenture, at least once in one daily
      newspaper of general circulation in each city in which the principal of
      any of the bonds shall be payable, or, if all bonds outstanding shall be
      registered bonds without coupons or coupon bonds registered as to
      principal, such notice shall be sufficiently given if mailed, first class,
      postage prepaid, and registered if the Company so elects, to each
      registered holder of bonds at the last address of such holder appearing on
      the registry books, such publication or mailing, as the case may be, to be
      made not less than thirty days prior to such execution. Any failure of the
      Company to give such notice, or any defect therein, shall not, however, in
      any way impair or affect the validity of any such supplemental indenture.

      SECTION 5. As supplemented and amended as above set forth, the Indenture
is in all respects ratified and confirmed, and the Indenture and all indentures
supplemental thereto shall be read, taken and construed as one and the same
instrument.

      SECTION 6. Nothing contained in this Supplemental Indenture shall, or
shall be construed to, confer upon any person other than a holder of bonds
issued under the Indenture, as supplemented and amended as above set forth, the
Company, the Trustee and the Agent, for the benefit of the Banks (as defined in
the Credit Agreement), any right or interest to avail himself of any benefit
under any provision of the Indenture, as so supplemented and amended.

      SECTION 7. The Trustee assumes no responsibility for or in respect of the
validity or sufficiency of this Supplemental Indenture or of the Indenture as
hereby supplemented or the due

                                      A-14
<PAGE>

execution hereof by the Company or for or in respect of the recitals and
statements contained herein (other than those contained in the sixth, seventh
and eighth recitals hereof), all of which recitals and statements are made
solely by the Company.

      SECTION 8. This Supplemental Indenture may be simultaneously executed in
several counterparts and all such counterparts executed and delivered, each as
an original, shall constitute but one and the same instrument.

      SECTION 9. In the event the date of any notice required or permitted
hereunder shall not be a Business Day, then (notwithstanding any other provision
of the Indenture or of any supplemental indenture thereto) such notice need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the date fixed for such notice.
"Business Day" means, with respect to this Section 9, any day, other than a
Saturday or Sunday, on which banks generally are open in New York, New York for
the conduct of substantially all of their commercial lending activities and on
which interbank wire transfers can be made on the Fedwire system.

      SECTION 10. This Supplemental Indenture and the Collateral Bonds shall be
governed by and deemed to be a contract under, and construed in accordance with,
the laws of the State of Michigan, and for all purposes shall be construed in
accordance with the laws of such state, except as may otherwise be required by
mandatory provisions of law.

                  GENERAL COUNSEL OR ASSISTANT GENERAL COUNSEL
                              OF THE COMPANY OR CMS

1. The Company is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Michigan.

2. The execution and delivery of the Credit Documents by the Company and the
performance by the Company of the Obligations have been duly authorized by all
necessary corporate action and proceedings on the part of the Company and will
not:

            (a) contravene the Company's Restated Articles of Incorporation, as
      amended, or bylaws;

            (b) contravene any law or any contractual restriction imposed by any
      indenture or any other agreement or instrument evidencing or governing
      indebtedness for borrowed money of the Company (including but not limited
      to the Company Indentures (as defined below));

            (c) result in or require the creation of any Lien upon or with
      respect to any of the Company's properties except (i) the lien of the
      Mortgage and Security Agreement and (ii) after the FMB Issue Date, the
      lien of the Indenture securing the Bonds; or

            (d) conflict with judicial orders or regulatory orders applicable to
      the Company.

      As used in this paragraph 2, "Company Indentures" means, collectively, (i)
the Indenture (as defined in the Credit Agreement), (ii) the Indenture dated as
of January 1, 1996, as supplemented and amended from time to time, between the
Company (formerly known as Consumers Power Company) and The Bank of New York, as
Trustee, and (iii) the Indenture dated as of February 1, 1998, as supplemented
and amended from time to time, between the Company and JPMorgan Chase Bank
(formerly known as The Chase Manhattan Bank), as Trustee.

3. The Credit Documents have been duly executed and delivered by the Company.

4. To the best of my knowledge, there is no pending or threatened action or
proceeding against the Company or any of its Consolidated Subsidiaries before
any court, governmental agency or arbitrator (except (i) to the extent described
in the Company's annual report on Form 10-K for the year ended December 31, 2005
and Current Report on Form 8-K filed by the Company on March 1, 2006, in each
case as filed with the SEC, and (ii) such other similar actions, suits and
proceedings predicated on the occurrence of the same events giving rise to any
actions, suits and proceedings described in the reports referred to in clause
(i) of this paragraph 4) which might reasonably be expected to materially
adversely affect the financial condition or

                                     B-1-1
<PAGE>

results of operations of the Company and its Consolidated Subsidiaries, taken as
a whole, or that would materially adversely affect the Company's ability to
perform its obligations under any Credit Document. To the best of my knowledge,
there is no litigation challenging the validity or the enforceability of any of
the Credit Documents.

5. No authorization or approval or other action by, and no notice to or filing
with, any governmental authority or regulatory body is required for the due
execution, delivery and performance by the Company of any Credit Document,
except for the authorization to issue, sell or guarantee secured and/or
unsecured short-term debt granted by the Federal Energy Regulatory Commission
(hereinafter the "FERC") in Docket No. ES04-31-000 (hereinafter the "FERC
Order"). The FERC Order is in full force and effect as of the date hereof.

6. The Company is not an "investment company" or a company "controlled" by an
"investment company" as such terms are defined in the Investment Company Act of
1940, as amended.

7. In a properly presented case, a Michigan court or a federal court applying
Michigan choice of law rules should give effect to the choice of law provisions
of the Agreement and should hold that the Agreement is to be governed by the
laws of the State of New York rather than the laws of the State of Michigan,
except in the case of those provisions set forth in the Agreement the
enforcement of which would contravene a fundamental policy of the State of
Michigan. In the course of our review of the Agreement, nothing has come to my
attention to indicate that any of such provisions would do so. Notwithstanding
the foregoing, even if a Michigan court or a federal court holds that the
Agreement is to be governed by the laws of the State of Michigan, the Agreement
constitutes a legal, valid and binding obligation of the Company, enforceable
under Michigan law (including usury provisions) against the Company in
accordance with its terms, subject to (a) the effect of applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement of creditors' rights generally and (b) the application of general
principles of equity (regardless of whether considered in a proceeding in equity
or at law).

                   MILLER, CANFIELD, PADDOCK AND STONE, P.L.C.

      1. The execution and delivery of the Mortgage and Security Agreement by
the Company and the performance by the Company of its obligations thereunder
will not conflict with the provisions of the Indenture (as defined in the Credit
Agreement).

      2. The Mortgage and Security Agreement is effective to create a valid and
perfected second lien on the collateral described therein.

                              OF THE COMPANY OR CMS

1. The Bonds, assuming due authentication in accordance with the terms of the
Indenture, are in due and proper form and, when delivered to the Agent pursuant
to the Bond Delivery Agreement, will evidence and secure the Obligations owing
under the Agreement and will be valid and enforceable obligations of the Company
in accordance with their terms, secured by the lien of the Indenture on an equal
and ratable basis with all other bonds issued thereunder and otherwise entitled
to the benefits provided by the Indenture.

2. The Indenture has been qualified under the Trust Indenture Act of 1939, as
amended, and the execution and delivery of the Supplemental Indenture will not
cause the Indenture to not be so qualified.

      (b) The Issuer covenants and agrees, and each Holder of Subordinated
Securities by his acceptance thereof likewise covenants and agrees, that the

subordinated to or pari passu with the Subordinated Notes, as the case may be,
including all other debt securities and guaranties in respect of those debt
securities, issued to any other trusts, partnerships or other entities
affiliated with the Issuer which act as a financing vehicle of the Issuer in
connection with the issuance of preferred securities by such entity or other
securities which rank pari passu with, or junior to, the Preferred Securities,
and (2) any indebtedness between or among the Issuer and its affiliates; and/or
(vii) renewals, extensions or refundings of any of the indebtedness referred to

distribution of assets of the Issuer referred to in this Article ____, the
Trustee and Holders of Subordinated Securities shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending,
or, subject to the provisions of Section ___ and ___, a certificate of the
receiver, trustee in bankruptcy, liquidating trustee or agent or other Person
making such payment or distribution to the Trustee or the Holders of
Subordinated Securities, for the purposes of ascertaining the Persons entitled
to participate in such distribution, the holders of the Senior Indebtedness and

amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article ____.

      Nothing contained in this Article ____ or elsewhere in this Indenture or
in any Subordinated Security is intended to or shall affect the obligation of
the Issuer to make, or prevent the Issuer from making, at any time except during
the pendency of any dissolution, winding up, liquidation or reorganization

distribution to or by the Trustee in respect of the Subordinated Securities.

existence of any facts which would prohibit the making of any payment or
distribution to or by the Trustee, unless at least two Business Days prior to
the making of any such payment, the Trustee shall have received written notice
thereof from the Issuer or from one or more holders of Senior Indebtedness or
from any representative thereof or from any trustee therefor, together with
proof satisfactory to the Trustee of such holding of Senior Indebtedness or of
the authority of such representative or trustee; and, prior to the receipt of
any such written notice, the Trustee, subject to the provisions of Sections ___
and ___, shall be entitled to assume conclusively that no such facts exist. The
Trustee shall be entitled to rely on the delivery to it of a written notice by a
Person representing himself to be a holder of Senior Indebtedness (or a
representative or trustee on behalf of the holder) to establish that such notice
has been given by a holder of Senior Indebtedness (or a representative of or
trustee on behalf of any such holder). In the event that the Trustee determines,

any Person as a holder of Senior Indebtedness to participate in any payments or
distribution pursuant of this Article ____, the Trustee may request such Person

Deposited with It. Money or Government Obligations deposited in trust with the
Trustee pursuant to and in accordance with Section ____ shall be for the sole
benefit of Securityholders and, to the extent allocated for the payment of

act on the part of the Issuer or by any act or failure to act, in good faith, by
any such holders or by any noncompliance by the Issuer with the terms of this
Indenture, regardless of any knowledge thereof which any such holder may have or
be otherwise charged with.

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness of the Issuer may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders of the
Subordinated Securities, without incurring responsibility to the Holders of the
Subordinated Securities and without impairing or releasing the subordination
provided in this Article ____ or the obligations hereunder of the Holders of the
Subordinated Securities to the holders of such Senior Indebtedness, do any one
or more of the following: (i) change the manner, place or terms of payment or

Issuer (whether in bankruptcy, insolvency or receivership proceedings or upon an
assignment for the benefit of creditors or otherwise) the immediate filing of a
claim for the unpaid balance of his Subordinated Securities in the form required
in said proceedings and causing said claim to be approved. If the Trustee does
not file a proper claim or proof of debt in the form required in such proceeding
prior to 30 days before the expiration of the time to file such claim or claims,
then the holders of Senior Indebtedness have the right to file and are hereby
authorized to file an appropriate claim for and on behalf of the Holders of said
Securities.

      Section 10. Right of Trustee to Hold Senior Indebtedness. The Trustee in
its individual capacity shall be entitled to all of the rights set forth in this
Article ____ in respect of any Senior Indebtedness at any time held by it to the
same extent as any other holder of Senior Indebtedness, and nothing in this

holder.

      With respect to the holders of Senior Indebtedness of the Issuer, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article ____, and no implied
covenants or obligations with respect to the holders of such Senior Indebtedness

liable to any holder of such Senior Indebtedness if it shall pay over or deliver
to Holders of Subordinated Securities, the Issuer or any other Person money or
assets to which any holder of such Senior Indebtedness shall be entitled by
virtue of this Article ____ or otherwise.

interest on the Bonds shall be deemed to be and treated in all respects as
payments of the Obligations, and such payments shall be distributed by the Agent

have been terminated and all Obligations shall have been paid in full.

      (b) Upon any permanent reduction in the Aggregate Commitment pursuant to
