Borrowing consisting of Eurodollar Rate Advances, or 9:00 A.M. (Chicago time) on
the Business Day of the proposed Borrowing in the case of a Borrowing consisting
of Base Rate Advances, by the Borrower to the Agent, which shall give to each
Lender prompt notice thereof by telecopier or telex. Each such notice of a
Borrowing (a "Notice of Borrowing") shall be by telephone, confirmed immediately
in writing signed by a Financial Officer in substantially the form of Exhibit B
hereto, specifying therein the requested (i) date of such Borrowing, (ii) Type
of Revolving Credit Advances comprising such Borrowing, (iii) aggregate amount
of such Borrowing, (iv) in the case of a Borrowing consisting of Eurodollar Rate
Advances, initial Interest Period for each such Revolving Credit Advance and (v)
wire transfer instructions. Each Lender shall, before 11:00 A.M. (Chicago time)
on the date of such Borrowing, make available for the account of its Applicable
Lending Office to the Agent at the Agent's Account, in same day funds, such
Lender's ratable portion of such Borrowing. After the Agent's receipt of such
funds and upon fulfillment of the applicable conditions set forth in Article
III, the Agent will make such funds available to the Borrower as specified in
the Notice of Borrowing.

            (b) Anything in subsection (a) above to the contrary
notwithstanding, (i) the Borrower may not select Eurodollar Rate Advances for
any Borrowing if the aggregate amount of such Borrowing is less than $5,000,000
or if the obligation of the Lenders to make Eurodollar Rate Advances shall then
be suspended pursuant to Section 2.07 or 2.11 and (ii) at no time shall the sum
of (x) all Borrowings comprising Eurodollar Rate Advances outstanding hereunder
and (y) all "Borrowings" comprising "Eurodollar Rate Advances" outstanding
under, and as such terms are defined in, the Three-Year Agreement, be greater
than ten.

            (c) Each Notice of Borrowing shall be irrevocable and binding on the
Borrower. In the case of any Borrowing that the related Notice of Borrowing
specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall
indemnify each Lender against any loss, cost or expense incurred by such Lender
as a result of any failure to fulfill on or before the date specified in such
Notice of Borrowing for such Borrowing the applicable conditions set forth in
Article III, including, without limitation, any loss (excluding loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds

                                       13


acquired by such Lender to fund the Revolving Credit Advance to be made by such
Lender as part of such Borrowing when such Revolving Credit Advance, as a result
of such failure, is not made on such date.

            (d) Unless the Agent shall have received notice from a Lender prior
to the date of any Borrowing that such Lender will not make available to the
Agent such Lender's ratable portion of such Borrowing, the Agent may assume that
such Lender has made such portion available to the Agent on the date of such
Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent that such Lender shall not
have so made such ratable portion available to the Agent, such Lender and the
Borrower severally agree to repay to the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Agent, at (i) in the case of the Borrower, the interest rate
applicable at the time to Revolving Credit Advances comprising such Borrowing
and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender
shall repay to the Agent such corresponding amount, such amount so repaid shall
constitute such Lender's Revolving Credit Advance as part of such Borrowing for
purposes of this Agreement.

            (e) The failure of any Lender to make the Revolving Credit Advance
to be made by it as part of any Borrowing shall not relieve any other Lender of
its obligation, if any, hereunder to make its Revolving Credit Advance on the
date of such Borrowing, but no Lender shall be responsible for the failure of
any other Lender to make the Revolving Credit Advance to be made by such other
Lender on the date of any Borrowing.

      SECTION 2.03. Fees.

            (a) Facility Fee. The Borrower agrees to pay to the Agent for the
account of each Lender a facility fee (the "Facility Fee") on the aggregate
amount of such Lender's Commitment from the date hereof in the case of each
Initial Lender and from effective date specified in the Assignment and
Acceptance pursuant to which it became a Lender in the case of each other Lender
until all of the Revolving Credit Advances have been paid in full and the
Commitments under this Agreement have been terminated at a rate per annum equal
to the Applicable Percentage in effect from time to time, payable in arrears
quarterly on the last day of each March, June, September and December, and on
the Revolver Termination Date.

            (b) Agent's Fees. The Borrower shall pay to the Agent for its own
account such fees as may from time to time be agreed between the Borrower and
the Agent.

            (c) Utilization Fee. If the aggregate outstanding amount of (i) all
Revolving Credit Advances hereunder and (ii) all "Revolving Credit Advances"
under (and as defined in) the Three-Year Agreement exceeds thirty-three percent
(33%) of the aggregate amount of (x) all Commitments hereunder and (y) all
"Commitments" under (and as defined in) the Three-Year Agreement then in effect
on such date (or, if any of the Commitments or "Commitments" have been
terminated, the aggregate amount of all Commitments and "Commitments" in effect
immediately prior to such termination), the Borrower will pay to the Agent for
the ratable benefit of the Lenders a utilization fee (the "Utilization Fee") at
a per annum rate equal to the Applicable

                                       14


Utilization Fee Rate in effect from time to time payable on the aggregate
outstanding amount of all Revolving Credit Advances on such date, payable in
arrears quarterly on the last day of each March, June, September and December,
and on the Revolver Termination Date.

      SECTION 2.04. Termination or Reduction of the Commitments. (a) The
Commitments shall be automatically terminated on the Revolver Termination Date.

            (b) The Borrower shall have the right, upon at least three Business
Days' notice to the Agent, to terminate in whole or reduce ratably in part the
unused portions of the respective Commitments of the Lenders, provided that each
partial reduction shall be in the aggregate amount of $5,000,000 or an integral
multiple of $1,000,000 in excess thereof. Once terminated, a Commitment or
portion thereof may not be reinstated.

      SECTION 2.05. Repayment of Revolving Credit Advances. The Borrower shall
repay to the Agent for the ratable account of the Lenders on the Revolver
Termination Date the aggregate principal amount of the Revolving Credit Advances
then outstanding.

      SECTION 2.06. Interest on Revolving Credit Advances. (a) Scheduled
Interest. The Borrower shall pay interest on the unpaid principal amount of each
Revolving Credit Advance owing to each Lender from the date of such Revolving
Credit Advance until such principal amount shall be paid in full, at the
following rates per annum:

                  (i) Base Rate Advances. During such periods as such Revolving
            Credit Advance is a Base Rate Advance, a rate per annum equal at all
            times to the sum of (x) the Base Rate in effect from time to time
            plus (y) the Applicable Margin in effect from time to time, payable
            in arrears quarterly on the last day of each March, June, September
            and December during such periods and on the date such Base Rate
            Advance shall be Converted or paid in full.

                  (ii) Eurodollar Rate Advances. During such periods as such
            Revolving Credit Advance is a Eurodollar Rate Advance, a rate per
            annum equal at all times during each Interest Period for such
            Revolving Credit Advance to the sum of (x) the Eurodollar Rate for
            such Interest Period for such Revolving Credit Advance plus (y) the
            Applicable Margin in effect from time to time, payable in arrears on
            the last day of such Interest Period and, if such Interest Period
            has a duration of more than three months, on each day that occurs
            during such Interest Period every three months from the first day of
            such Interest Period and on the date such Eurodollar Rate Advance
            shall be Converted or paid in full.

            (b) Default Interest. (i) Upon the occurrence and during the
continuance of an Event of Default, the Borrower shall pay interest on the
unpaid principal amount of each Revolving Credit Advance owing to each Lender,
payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above,
at a rate per annum equal at all times to 2% per annum above the rate per annum
required to be paid on such Revolving Credit Advance pursuant to clause (a)(i)
or (a)(ii) above, and (ii) the Borrower shall pay, to the fullest extent
permitted by law, the amount of any interest, fee or other amount payable
hereunder that is not paid when due, from the date such amount shall be due
until such amount shall be paid in full, payable in arrears on the date such

                                       15


amount shall be paid in full and on demand, at a rate per annum equal at all
times to 2% per annum above the rate per annum required to be paid on Base Rate
Advances pursuant to clause (a)(i) above.

      SECTION 2.07. Interest Rate Determination. (a) If applicable, each
Reference Bank agrees to furnish to the Agent timely information for the purpose
of determining each Eurodollar Rate. If any one or more of the Reference Banks
shall not furnish such timely information to the Agent for the purpose of
determining any such interest rate, the Agent shall determine such interest rate
on the basis of timely information furnished by the remaining Reference Banks.
The Agent shall give prompt notice to the Borrower and the Lenders of the
applicable interest rate determined by the Agent for purposes of Section
2.06(a)(i) or (ii), and the rate, if any, furnished by each Reference Bank for
the purpose of determining the interest rate under Section 2.06(a)(ii).

            (b) If, with respect to any Eurodollar Rate Advances, the Required
Lenders notify the Agent that the Eurodollar Rate for any Interest Period for
such Eurodollar Rate Advances will not adequately reflect the cost to such
Required Lenders of making, funding or maintaining their respective Eurodollar
Rate Advances for such Interest Period, the Agent shall forthwith so notify the
Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to
make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances
shall be suspended until the Agent shall notify the Borrower and the Lenders
that the circumstances causing such suspension no longer exist.

            (c) If the Borrower shall fail to select the duration of any
Interest Period for any Eurodollar Rate Advances in accordance with the
provisions contained in the definition of "Interest Period" in Section 1.01, the
Agent will forthwith so notify the Borrower and the Lenders and such Eurodollar
Rate Advances will automatically, on the last day of the then existing Interest
Period therefor, Convert into Base Rate Advances.

            (d) On the date on which the aggregate unpaid principal amount of
Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment
or prepayment or otherwise, to less than $5,000,000, such Eurodollar Rate
Advances shall automatically Convert into Base Rate Advances.

            (e) Upon the occurrence and during the continuance of any Event of
Default, (i) each Eurodollar Rate Advance will automatically, on the last day of
the then existing Interest Period therefor, Convert into a Base Rate Advance and
(ii) the obligation of the Lenders to make, or to Convert Revolving Credit
Advances into, Eurodollar Rate Advances shall be suspended.

            (f) If the Service is not available or a rate does not timely appear
on the Service and fewer than two Reference Banks furnish timely information to
the Agent for determining the Eurodollar Rate for any Eurodollar Rate Advances:

                  (i) the Agent shall forthwith notify the Borrower and the
            Lenders that the interest rate cannot be determined for such
            Eurodollar Rate Advances,

                                       16


                  (ii) with respect to Eurodollar Rate Advances, each such
            Eurodollar Rate Advance will automatically, on the last day of the
            then existing Interest Period therefor, Convert into a Base Rate
            Advance (or if such Advance is then a Base Rate Advance, will
            continue as a Base Rate Advance), and

                  (iii) the obligation of the Lenders to make Eurodollar Rate
            Advances or to Convert Revolving Credit Advances into Eurodollar
            Rate Advances shall be suspended until the Agent shall notify the
            Borrower and the Lenders that the circumstances causing such
            suspension no longer exist.

      SECTION 2.08. Optional Conversion of Revolving Credit Advances. The
Borrower may on any Business Day, upon notice given to the Agent not later than
10:00 A.M. (Chicago time) on the third Business Day prior to the date of the
proposed Conversion and subject to the provisions of Sections 2.07 and 2.11,
Convert all Revolving Credit Advances of one Type comprising the same Borrowing
into Revolving Credit Advances of the other Type (it being understood that such
Conversion of a Revolving Credit Advance or of its Interest Period does not
constitute a repayment or prepayment of such Revolving Credit Advance);
provided, however, that any Conversion of Eurodollar Rate Advances into Base
Rate Advances shall be made only on the last day of an Interest Period for such
Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar
Rate Advances shall be in an amount not less than the minimum amount specified
in Section 2.02(b) and no Conversion of any Revolving Credit Advances shall
result in more separate Borrowings than permitted under Section 2.02(b). Each
such notice of a Conversion shall, within the restrictions specified above,
specify (i) the date of such Conversion, (ii) the Revolving Credit Advances to
be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the
duration of the initial Interest Period for each such Eurodollar Rate Advance.
Each notice of Conversion shall be irrevocable and binding on the Borrower.

      SECTION 2.09. Prepayments of Revolving Credit Advances. (a) Optional
Prepayment. The Borrower may on any Business Day, upon notice given to the Agent
not later than 10:00 A.M. (Chicago time), (i) on the same day for Base Rate
Advances and (ii) on the second Business Day prior to the prepayment in the case
of Eurodollar Rate Advances stating the proposed date and aggregate principal
amount of the prepayment (and if such notice is given the Borrower shall) prepay
the outstanding principal amount of the Revolving Credit Advances comprising
part of the same Borrowing in whole or ratably in part, together with accrued
interest to the date of such prepayment on the principal amount prepaid;
provided, however, that (x) each partial prepayment shall be in an aggregate
principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess
thereof and (y) in the event of any such prepayment of a Eurodollar Rate
Advance, the Borrower shall be obligated to reimburse the Lenders in respect
thereof pursuant to Section 8.04(c).

            (b) Mandatory Prepayment. The Borrower shall, upon five Business
Days notice from the Agent given at the request or with the consent of the
Required Lenders, prepay the aggregate principal amount outstanding plus all
interest thereon and all other amounts payable hereunder or under the Notes, in
the event that any Person or two or more Persons acting in concert (other than
DTE Energy or any of its Subsidiaries) shall have acquired beneficial ownership
(within the meaning of Rule 13d-3 of the Securities and Exchange Commission
under

                                       17


the Securities Exchange Act of 1934), directly or indirectly, of Voting Stock of
the Borrower (or other securities convertible into such Voting Stock)
representing 30% or more of the combined voting power of all Voting Stock of the
Borrower.

      SECTION 2.10. Increased Costs. (a) If, due to either (i) the introduction
of or any change in or in the interpretation of any law or regulation or (ii)
the compliance with any guideline or request from any central bank or other
governmental authority (whether or not having the force of law), there shall be
any increase in the cost to any Lender of agreeing to make or making, funding or
maintaining Eurodollar Rate Advances (excluding for purposes of this Section
2.10 any such increased costs resulting from taxes (as to which Section 2.13
shall govern), then the Borrower shall from time to time, upon demand by such
Lender (with a copy of such demand to the Agent), pay to the Agent for the
account of such Lender additional amounts sufficient to compensate such Lender
for such increased cost. A certificate as to the amount of such increased cost,
submitted to the Borrower and the Agent by such Lender, shall be conclusive and
binding for all purposes, absent manifest error.

            (b) If any Lender determines that compliance with any law or
regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and that the amount of such
capital is increased by or based upon the existence of such Lender's commitment
to lend hereunder and other commitments of this type, then, upon demand by such
Lender (with a copy of such demand to the Agent), the Borrower shall pay to the
Agent for the account of such Lender, from time to time as specified by such
Lender, additional amounts sufficient to compensate such Lender or such
corporation in the light of such circumstances, to the extent that such Lender
reasonably determines such increase in capital to be allocable to the existence
of such Lender's commitment to lend hereunder. A certificate as to such amounts
submitted to the Borrower and the Agent by such Lender shall be conclusive and
binding for all purposes, absent manifest error.

            (c) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.10, the
Borrower may, upon payment of such amounts and subject to the requirements of
Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial institution shall be an Eligible Assignee and shall
assume the Commitments of such Lender and purchase the Revolving Credit Advances
held by such Lender in accordance with Section 8.07, provided, however, that (i)
no Default shall have occurred and be continuing, (ii) the Borrower shall have
satisfied all of its obligations in connection with the Loan Documents with
respect to such Lender, and (iii) if such assignee is not a Lender, (A) such
assignee is acceptable to the Agent and (B) the Borrower shall have paid the
Agent a $3,000 administrative fee.

      SECTION 2.11. Illegality. Notwithstanding any other provision of this
Agreement, if any Lender shall notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation makes it unlawful,
or any central bank or other governmental authority asserts that it is unlawful,
for any Lender or its Eurodollar Lending Office to perform its obligations
hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar
Rate Advances hereunder, (i) each Eurodollar Rate Advance will

                                       18


automatically, upon such demand, Convert into a Base Rate Advance or a Revolving
Credit Advance that bears interest at the rate set forth in Section 2.06(a)(i),
as the case may be, and (ii) the obligation of the Lenders to make Eurodollar
Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate
Advances shall be suspended until the Agent shall notify the Borrower and the
Lenders that the circumstances causing such suspension no longer exist.

      SECTION 2.12. Payments and Computations. (a) The Borrower shall make each
payment hereunder and under the Notes not later than 10:00 A.M. (Chicago time)
on the day when due in U.S. dollars to the Agent at the Agent's Account in same
day funds and without set off, deduction or counterclaim other than deductions
on account of taxes. The Agent will promptly thereafter cause to be distributed
like funds relating to the payment of principal or interest, Facility Fees or
the Utilization Fee ratably (other than amounts payable pursuant to Section
2.10, 2.13 or 8.04(c)) to the Lenders for the account of their respective
Applicable Lending Offices, and like funds relating to the payment of any other
amount payable to any Lender to such Lender for the account of its Applicable
Lending Office, in each case to be applied in accordance with the terms of this
Agreement. Upon its acceptance of an Assignment and Acceptance and recording of
the information contained therein in the Register pursuant to Section 8.07(c),
from and after the effective date specified in such Assignment and Acceptance,
the Agent shall make all payments hereunder and under the Notes in respect of
the interest assigned thereby to the Lender assignee thereunder, and the parties
to such Assignment and Acceptance shall make all appropriate adjustments in such
payments for periods prior to such effective date directly between themselves.

            (b) The Borrower hereby authorizes each Lender, if and to the extent
payment owed to such Lender is not made when due hereunder or under the Note
held by such Lender, to charge from time to time against any or all of the
Borrower's accounts with such Lender any amount so due.

            (c) All computations of interest based on the Base Rate shall be
made by the Agent on the basis of a year of 365 or 366 days, as the case may be,
and all computations of interest based on the Eurodollar Rate or the Federal
Funds Rate and of Facility Fees and the Utilization Fee shall be made by the
Agent on the basis of a year of 360 days, in each case for the actual number of
days (including the first day but excluding the last day) occurring in the
period for which such interest, Facility Fees or the Utilization Fee are
payable. Each determination by the Agent of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error.

            (d) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest, Facility Fee or the
Utilization Fee, as the case may be; provided, however, that, if such extension
would cause payment of interest on or principal of Eurodollar Rate Advances to
be made in the next following calendar month, such payment shall be made on the
next preceding Business Day.

            (e) Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Lenders hereunder that the
Borrower will not make such

                                       19


payment in full, the Agent may assume that the Borrower has made such payment in
full to the Agent on such date and the Agent may, in reliance upon such
assumption, cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender. If and to the extent the Borrower
shall not have so made such payment in full to the Agent, each Lender shall
repay to the Agent forthwith on demand such amount distributed to such Lender
together with interest thereon, for each day from the date such amount is
distributed to such Lender until the date such Lender repays such amount to the
Agent, at the Federal Funds Rate.

      SECTION 2.13. Taxes. (a) Subject to the exclusions set forth below in this
Section 2.13(a) and, if applicable, compliance with Section 2.13(e), any and all
payments by the Borrower hereunder or under the Notes shall be made, in
accordance with Section 2.12, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Lender and the Agent, any and all present or future taxes, levies,
imposts, deductions, charges or withholdings imposed on its income, and
franchise taxes imposed on it in lieu of income taxes, (i) by the jurisdiction
under the laws of which such Lender or the Agent (as the case may be) is
organized or any political subdivision thereof and, (ii) in the case of each
Lender, by the jurisdiction of such Lender's Applicable Lending Office or any
political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities in respect of payments
hereunder or under the Notes being hereinafter referred to as "Taxes").
Notwithstanding the above, if the Borrower shall be required by law to deduct
any Taxes from or in respect of any sum payable hereunder or under any Note to
any Lender or the Agent, the Borrower will so deduct and (i) the sum payable
shall be increased as may be necessary so that after making all such deductions
on account of Taxes (including deductions on account of Taxes applicable to
additional sums payable under this Section 2.13) such Lender or the Agent (as
the case may be) receives an amount equal to the sum it would have received had
no such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law.

            (b) The Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or under the Notes or from the
execution, delivery or registration of this Agreement or the Notes (hereinafter
referred to as "Other Taxes").

            (c) Without duplication of the Borrower's payment obligations on
account of Taxes or Other Taxes pursuant to Sections 2.13(a) and (b), the
Borrower shall indemnify each Lender and the Agent for the full amount of Taxes
or Other Taxes (including, without limitation, any Taxes imposed by any
jurisdiction on amounts payable under this Section 2.13) imposed on or paid by
such Lender or the Agent (as the case may be) and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto.
This indemnification shall be made within 30 days from the date such Lender or
the Agent (as the case may be) makes written demand therefor.

            (d) Within 30 days after the date of any payment of Taxes, the
Borrower shall furnish to the Agent, at its address referred to in Section 8.02,
the original or a certified copy of a receipt evidencing payment thereof. In the
case of any payment hereunder or under the Notes by

                                       20


or on behalf of the Borrower through an account or branch outside the United
States or by or on behalf of the Borrower by a payor that is not a United States
person, if the Borrower determines that no Taxes are payable in respect thereof,
the Borrower shall furnish, or shall cause such payor to furnish, to the Agent,
at such address, an opinion of counsel acceptable to the Agent stating that such
payment is exempt from Taxes. For purposes of this subsection (d) and subsection
(e), the terms "United States" and "United States person" shall have the
meanings specified in Section 7701 of the Internal Revenue Code.

            (e) Each Lender organized under the laws of a jurisdiction outside
the United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Initial Lender and on the date of the Assignment
and Acceptance pursuant to which it becomes a Lender in the case of each other
Lender, and from time to time thereafter as requested in writing by the Borrower
(but only so long as such Lender remains lawfully able to do so), shall provide
each of the Agent and the Borrower with two original Internal Revenue Service
Form W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed
by the Internal Revenue Service, certifying that such Lender is exempt from
United States withholding tax on payments pursuant to this Agreement or the
Notes. If any form or document referred to in this subsection (e) requires the
disclosure of information, other than information necessary to compute the tax
payable and information required on the date hereof by Internal Revenue Service
Form W-8BEN or W-8ECI, that the Lender reasonably considers to be confidential,
the Lender shall give notice thereof to the Borrower and shall not be obligated
to include in such form or document such confidential information, however, such
a Lender will not be entitled to any payment or indemnification on account of
any Taxes imposed by the United States.

            (f) Notwithstanding any provision to the contrary in this Agreement,
the Borrower will not be obligated to make payments on account of or indemnify
the Lenders or the Agents for any present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
or any present or future stamp or other documentary taxes or property taxes,
charges or similar levies that are neither Taxes nor Other Taxes.

            (g) For any period with respect to which a Lender has failed to
provide the Borrower with the appropriate form described in Section 2.13(e)
(other than if such failure is due to a change in law occurring subsequent to
the date on which a form originally was required to be provided, or if such form
otherwise is not required under the first sentence of subsection (e) above),
such Lender shall not be entitled to indemnification under Section 2.13(a) or
(c) with respect to Taxes imposed by the United States by reason of such
failure; provided, however, that should a Lender become subject to Taxes because
of its failure to deliver a form required hereunder, the Borrower shall take
such steps as the Lender shall reasonably request to assist the Lender to
recover such Taxes.

            (h) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.13, the
Borrower may, upon payment of such amounts and subject to the requirements of
Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial institution shall be an Eligible Assignee and shall
assume the Commitments of such Lender and purchase the Revolving Credit Advances
held by such Lender in accordance with Section 8.07, provided, however, that (i)
no Default shall have occurred and be continuing, (ii) the Borrower shall have
satisfied all of its

                                       21


obligations in connection with the Loan Documents with respect to such Lender,
and (iii) if such assignee is not a Lender, (A) such assignee is acceptable to
the Agent and (B) the Borrower shall have paid the Agent a $3,000 administrative
fee.

            (i) Notwithstanding any provision to the contrary in this Agreement,
in the event that a Lender that is not an Initial Lender and who purchased its
interest in this Agreement without the consent of the Borrower pursuant to
Section 8.07(a), seeks (i) payment of additional amounts pursuant to Section
2.13(a), (ii) payment of Other Taxes pursuant to Section 2.13(b), or (iii)
indemnification for Taxes or Other Taxes pursuant to Section 2.13(c), the amount
of any such payment or indemnification will be no greater than what it would
have been had the Initial Lender not transferred, assigned or sold its interest
in this Agreement.

      SECTION 2.14. Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Revolving Credit Advances owing to it
(other than pursuant to Section 2.10, 2.13 or 8.04(c)) in excess of its ratable
share of payments on account of the Revolving Credit Advances obtained by all
the Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the Revolving Credit Advances owing to them as shall be
necessary to cause such purchasing Lender to share the excess payment ratably
with each of them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from such purchasing Lender, such purchase from
each Lender shall be rescinded and such Lender shall repay to the purchasing
Lender the purchase price to the extent of such recovery together with an amount
equal to such Lender's ratable share (according to the proportion of (i) the
amount of such Lender's required repayment to (ii) the total amount so recovered
from the purchasing Lender) of any interest or other amount paid or payable by
the purchasing Lender in respect of the total amount so recovered. The Borrower
agrees that any Lender so purchasing a participation from another Lender
pursuant to this Section 2.14 may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off) with respect
to such participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation.

      SECTION 2.15. Use of Proceeds. The proceeds of the Revolving Credit
Advances shall be available (and the Borrower agrees that it shall use such
proceeds) solely for general corporate purposes, including commercial paper
liquidity, of the Borrower and its Subsidiaries.

      SECTION 2.16. Reserved.

      SECTION 2.17. Noteless Agreement; Evidence of Indebtedness.

            (a) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of the Borrower to such
Lender resulting from each Revolving Credit Advance made by such Lender from
time to time, including the amounts of principal and interest payable and paid
to such Lender from time to time hereunder.

            (b) The Agent shall also maintain accounts in which it will record
(i) the date and the amount of each Revolving Credit Advance made hereunder and
the Interest Period, if any, applicable thereto, (ii) the amount of any
principal or interest due and payable or to become

                                       22


due and payable from the Borrower to each Lender hereunder, (iii) the effective
date and amount of each Assignment and Acceptance delivered to and accepted by
it and the parties thereto pursuant to Section 8.07, (iv) the amount of any sum
received by the Agent hereunder from the Borrower and each Lender's share
thereof, and (v) all other appropriate debits and credits as provided in this
Agreement, including, without limitation, all fees, charges, expenses and
interest.

            (c) The entries maintained in the accounts maintained pursuant to
clauses (a) and (b) above shall be prima facie evidence of the existence and
amounts of the obligations hereunder and under the Notes therein recorded;
provided, however, that the failure of the Agent or any Lender to maintain such
accounts or any error therein shall not in any manner affect the obligation of
the Borrower to repay such obligations in accordance with their terms.

            (d) Any Lender may request that its Revolving Credit Advances be
evidenced by a promissory note representing its Revolving Credit Advances
substantially in the form of Exhibit A (each, a "Note"). In such event, the
Borrower shall prepare, execute and deliver to such Lender such Note payable to
the order of such Lender. Thereafter, the Revolving Credit Advances evidenced by
each such Note and interest thereon shall at all times (including after any
assignment pursuant to Section 8.07) be represented by one or more Notes payable
to the order of the payee named therein or any assignee pursuant to Section
8.07, except to the extent that any such Lender or assignee subsequently returns
any such Note for cancellation and requests that such Revolving Credit Advances
once again be evidenced as described in clauses (a) and (b) above.

Subsidiaries to comply with all applicable laws, rules, regulations and orders,
such compliance to include, without limitation, compliance with ERISA and

whereupon the same shall forthwith terminate, and (ii) shall at the request, or
may with the consent, of the Required Lenders, by notice to the Borrower,
declare the Revolving Credit Advances, all interest thereon and all other
amounts payable under this Agreement to be forthwith due and payable, whereupon
the Revolving Credit Advances, all such interest and all such amounts shall
become and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by the
Borrower; provided, however, that in the event of an actual or deemed entry of
an order for relief with respect to the Borrower under the Federal Bankruptcy
Code, (A) the obligation of each Lender to make Revolving Credit Advances shall
automatically be terminated and (B) the Revolving Credit Advances, all such

                                  ARTICLE VII:
                                   THE AGENT

                                       33


      SECTION 7.01. Authorization and Action. Each Lender hereby appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers and discretion under this Agreement as are delegated to the Agent by
the terms hereof, together with such powers and discretion as are reasonably
incidental thereto. As to any matters not expressly provided for by this
Agreement (including, without limitation, enforcement or collection of the
Revolving Credit Advances), the Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Required Lenders (or all of the Lenders to the
extent required by the terms of this Agreement), and such instructions shall be
binding upon all Lenders and all holders of Revolving Credit Advances; provided,
however, that the Agent shall not be required to take any action that exposes
the Agent to personal liability or that is contrary to this Agreement or
applicable law. The Agent agrees to give to each Lender prompt notice of each
notice given to it by the Borrower pursuant to the terms of this Agreement.

      SECTION 7.02. Agent's Reliance, Etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it or them under or in connection with this Agreement,
except for its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Agent: (i) may treat the
payee in respect of any Revolving Credit Advance as the owner thereof until the
Agent receives and accepts an Assignment and Acceptance entered into by the
Lender that is the payee in respect of such Revolving Credit Advance, as
assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07;
(ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (iii) makes
no warranty or representation to any Lender and shall not be responsible to any
Lender for any statements, warranties or representations (whether written or
oral) made in or in connection with this Agreement; (iv) shall not have any duty
to ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of this Agreement on the part of the Borrower or
to inspect the property (including the books and records) of the Borrower; (v)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to
be created under or in connection with, any Loan Document or any other
instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

      SECTION 7.03. Bank One and Affiliates. With respect to its Commitment, the
Revolving Credit Advances made by it and any Note issued to it, Bank One shall
have the same rights and powers under this Agreement as any other Lender and may
exercise the same as though it were not the Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Bank One in its
individual capacity. Bank One and its Affiliates may accept deposits from, lend
money to, act as trustee under indentures of, accept investment banking
engagements from and generally engage in any kind of business with, the
Borrower, any of its Subsidiaries and any Person who may do business with or own
securities of the Borrower or any such Subsidiary, all as if Bank One were not
the Agent and without any duty to account therefor to the Lenders.

                                       34


      SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Agent or any other Lender and
based on the financial statements referred to in Section 4.01 and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

      SECTION 7.05. Indemnification. The Lenders agree to indemnify the Agent
(to the extent not reimbursed by the Borrower), ratably according to the
respective principal amounts of their respective Revolving Credit Advances (or
if no Revolving Credit Advances are at the time outstanding or if any Revolving
Credit Advances are owing to Persons that are not Lenders, ratably according to
the respective amounts of their Commitments), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against the Agent in any way relating to or
arising out of any Loan Document or any action taken or omitted by the Agent
under any Loan Document, provided that no Lender shall be liable for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agent's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender agrees to reimburse the Agent promptly upon demand for its ratable
share of any out-of-pocket expenses (including counsel fees) incurred by the
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, any Loan Document, to the extent that the Agent is not
reimbursed for such expenses by the Borrower.

      SECTION 7.06. Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower and may be removed at any
time with or without cause by the Required Lenders. Upon any such resignation or
removal, the Required Lenders shall have the right to appoint a successor Agent.
If no successor Agent shall have been so appointed by the Required Lenders, and
shall have accepted such appointment, within 30 days after the retiring Agent's
giving of notice of resignation or the Required Lenders' removal of the retiring
Agent, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent, which shall be a commercial bank organized under the laws of
the United States of America or of any State thereof and having a combined
capital and surplus of at least $50,000,000. 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, discretion,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring Agent's resignation or removal hereunder as Agent, the provisions of
this Article VII shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Agent under this Agreement.

      SECTION 7.07. Co-Documentation Agents. None of the Lenders identified in
this Agreement as a Co-Documentation Agent shall have any right, power,
obligation, liability, responsibility or duty under this Agreement other than
those applicable to all Lenders as such.

                                       35


Without limiting the foregoing, none of such Lenders shall have or be deemed to
have a fiduciary relationship with any Lender. Each Lender hereby makes the same
acknowledgments with respect to such Lenders as it makes with respect to the
Agent in Section 7.04.

                                 ARTICLE VIII:
                                 MISCELLANEOUS

      SECTION 8.01. Amendments, Etc. No amendment or waiver of any provision of
this Agreement or the Notes, nor consent to any departure by the Borrower
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Required Lenders, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no amendment, waiver or consent shall, unless in
writing and signed by all the Lenders affected thereby, do any of the following:
(a) waive any of the conditions specified in Section 3.01, (b) increase the
Commitments of the Lenders or subject the Lenders to any additional obligations,
(c) reduce the principal of, or interest on, the Revolving Credit Advances or
any fees or other amounts payable hereunder, (d) postpone any date fixed for any

fees or other amounts payable hereunder, (e) change the percentage of the
Commitments or of the aggregate unpaid principal amount of the Revolving Credit
Advances, or the number of Lenders, that shall be required for the Lenders or
any of them to take any action hereunder or (f) amend this Section 8.01; and
provided further that no amendment, waiver or consent shall, unless in writing
and signed by the Agent in addition to the Lenders required above to take such
action, affect the rights or duties of the Agent under this Agreement or any
Note.

      SECTION 8.02. Notices, Etc.

(a) All notices and other communications provided for hereunder shall be in

            (b) (i) Except as otherwise provided in Section 5.01(h), the
Borrower shall provide to the Agent all information, documents and other
materials that such Person is obligated

                                       36


to furnish to the Agent pursuant to this Agreement and the other Loan Documents,
including, without limitation, all notices, requests, financial statements,
financial and other reports, certificates and other information materials, but
excluding any such communication that (i) relates to a Notice of Borrowing or
other request for a new, or a conversion of an existing, Borrowing or other

acceptable to the Agent to such electronic mail address as the Agent shall
identify to the Borrower. In addition, the Borrower shall continue to provide
the Communications to the Agent in the manner specified in this Agreement but
only to the extent requested by the Agent. The Borrower further agrees that the
Agent may make the Communications available to the Lenders by posting the
Communications on Intralinks, or a substantially similar electronic transmission
system mutually agreeable to the Agent and the Borrower (the "Platform").
Nothing in this Section 8.02(b) shall prejudice the right of the Agent to give
any notice or other communication pursuant hereto or to any other Loan Document
in any other manner specified herein or therein.

                  (ii) The Agent agrees that the receipt of the Communications
            by the Agent at its e-mail address set forth in clause (i) above
            shall constitute effective delivery of the Communications to the
            Agent for purposes of each Loan Document. The Borrower agrees that
            e-mail notice to it (at the address provided pursuant to the next
            sentence and deemed delivered as provided in subclause (iii) below)
            specifying that Communications have been posted to the Platform
            shall constitute effective delivery of such Communications to such
            Person under the Loan Documents. The Borrower agrees (A) 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 Person to which the foregoing notices may be
            sent by electronic transmission and (B) that the foregoing notices
            may be sent to such e-mail address.

                  (iii) Each party hereto agrees that any electronic
            communication referred to in this clause (b) 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, however, that if such Communication is received by the
            Agent after the normal business hours of the Agent, such
            Communication shall be deemed delivered at the opening of business
            on the next Business Day for the Agent; provided, further, that in
            the event that the Agent's e-mail system shall be unavailable for
            receipt of any Communication, Borrower may deliver such
            Communication to the Agent in a manner mutually agreeable to the
            Agent and the Borrower.

                                       37


                  (iv) The Borrower acknowledges and agrees that the
            distribution of the Communications and other material through an
            electronic medium is not necessarily secure and that there are
            confidentiality and other risks associated with such distribution.
            THE BORROWER FURTHER ACKNOWLEDGES AND AGREES AS FOLLOWS: (A) THE
            PLATFORM IS PROVIDED "AS IS" AND "AS AVAILABLE"; (B) BANK ONE DOES
            NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR
            THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR
            ERRORS OR OMISSIONS IN THE COMMUNICATIONS; AND (C) NO WARRANTY OF
            ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT
            LIMITATION, 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 BANK ONE IN
            CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM.

                  (v) This clause (b) shall terminate on the date that neither
            Bank One or any of its affiliates is the Agent under this Agreement.

      SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender or
the Agent to exercise, and no delay in exercising, any right hereunder or under
any Note shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or the
exercise of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

      SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to pay on
demand, upon presentation of a statement of account and absent manifest error,
all reasonable costs and reasonable expenses of the Agent in connection with the
preparation, execution, delivery, administration, modification and amendment of
the Loan Document and the other documents to be delivered hereunder and
thereunder, including, without limitation, (A) all due diligence, syndication
(including printing, distribution and bank meetings), transportation, computer,
duplication, appraisal, consultant, and audit expenses and (B) the reasonable
fees and reasonable expenses of counsel for the Agent with respect thereto and
with respect to advising the Agent as to its rights and responsibilities under
the Loan Documents. The Borrower further agrees to pay on demand all reasonable
costs and reasonable expenses of the Agent and the Lenders, if any (including,
without limitation, reasonable internal and external counsel fees and expenses,
provided such fees and expenses are not duplicative), in connection with the
"workout", restructuring or enforcement (whether through negotiations, legal
proceedings or otherwise) of the Loan Documents and the other documents to be
delivered hereunder, including, without limitation, reasonable fees and expenses
of counsel for the Agent and each Lender in connection with the enforcement of
rights under this Section 8.04(a).

            (b) The Borrower agrees to indemnify, to the extent legally
permissible, and hold harmless the Agent and each Lender and each of their
Affiliates and their officers, directors, employees, agents and advisors (each,
an "Indemnified Party") from and against any and all claims, damages, losses,
liabilities and expenses (including, without limitation, reasonable fees and
expenses of counsel) that may be incurred by or asserted or awarded against any
Indemnified

                                       38


Party, in each case arising out of or in connection with or by reason of, or in
connection with the preparation for a defense of, any investigation, litigation
or proceeding arising out of, related to or in connection with (i) the Loan
Documents, any of the transactions contemplated herein or therein or the actual
or proposed use of the proceeds of the Revolving Credit Advances or (ii) the
actual or alleged presence of Hazardous Materials on any property of the
Borrower or any of its Subsidiaries or any Environmental Action relating in any
way to the Borrower or any of its Subsidiaries, in each case whether or not such
investigation, litigation or proceeding is brought by the Borrower, its
directors, shareholders or creditors or an Indemnified Party or any other Person
or any Indemnified Party is otherwise a party thereto and whether or not the
transactions contemplated hereby are consummated, except to the extent such
claim, damage, loss, liability or expense is found in a final, non-appealable
judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence or willful misconduct. The Borrower also
agrees not to assert any claim against the Agent, any Lender, any of their
Affiliates, or any of their respective directors, officers, employees, attorneys
and agents, on any theory of liability, for special, indirect, consequential or
punitive damages arising out of or otherwise relating to the Loan Documents, any
of the transactions contemplated herein or therein or the actual or proposed use
of the proceeds of the Revolving Credit Advances.

            (c) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance is made by the Borrower to or for the account of a Lender other
than on the last day of the Interest Period for such Revolving Credit Advance,
as a result of a payment or Conversion pursuant to Section 2.07(d) or (e), 2.09
or 2.11, acceleration of the maturity of the Revolving Credit Advances pursuant
to Section 6.01, or for any other reason, the Borrower shall, upon demand by
such Lender (with a copy of such demand to the Agent), pay to the Agent for the
account of such Lender any amounts required to compensate such Lender for any
additional losses, costs or expenses that it may reasonably incur as a result of
such payment or Conversion, including, without limitation, any loss (including
loss of anticipated profits), cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by any Lender to
fund or maintain such Revolving Credit Advance.

            (d) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
Sections 2.10, 2.13 and 8.04 shall survive the payment in full of principal,
interest and all other amounts payable hereunder and under the Notes.

      SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making of the request or the
granting of the consent specified by Section 6.01 to authorize the Agent to
declare the Revolving Credit Advances due and payable pursuant to the provisions
of Section 6.01, each Lender and each of its Affiliates is hereby authorized at
any time and from time to time, to the fullest extent permitted by law, to set
off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Lender or such Affiliate to or for the credit or the account of the
Borrower against any and all of the obligations of the Borrower now or hereafter
existing under the Loan Documents and any Note held by such Lender, whether or
not such Lender shall have made any demand under this Agreement or such Note and
although such obligations may be unmatured. Each Lender agrees promptly to
notify the Borrower after any such set-off and application, provided that the
failure

                                       39


to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender and its Affiliates under this Section are
in addition to other rights and remedies (including, without limitation, other
rights of set-off) that such Lender and its Affiliates may have.

      SECTION 8.06. Binding Effect. This Agreement shall become effective (other
than Section 2.01, which shall only become effective upon satisfaction of the
conditions precedent set forth in Section 3.01) when it shall have been executed
by the Borrower and the Agent and when the Agent shall have been notified by
each Initial Lender that such Initial Lender has executed it and thereafter
shall be binding upon and inure to the benefit of the Borrower, the Agent and
each Lender and their respective successors and assigns, except that the
Borrower shall not have the right to assign its rights hereunder or any interest
herein without the prior written consent of the Lenders to any Person.

      SECTION 8.07. Assignments, Designations and Participations. (a) Each
Lender may, with the prior consent of the Agent (which consent shall not be
unreasonably withheld and which consent shall not be required in the event of an
assignment or grant pursuant to Sections 8.07(g) or (h))) and (for so long as no
Default has occurred and is continuing) the Borrower (which consent shall not be
unreasonably withheld and which consent shall not be required in the event of an
assignment or grant pursuant to Sections 8.07(g) or (h)) assign to one or more
Persons all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the
Revolving Credit Advances owed to it and any Note or Notes held by it);
provided, however, that (i) each such assignment shall be of a constant, and not
a varying, percentage of all rights and obligations under this Agreement and,
for so long as no Default has occurred and is continuing, shall be made
concurrently with an assignment in a ratable amount of such Lender's rights and
obligations (if any) under the Three-Year Agreement (including, without
limitation, all or a portion of its "Commitment", "Revolving Credit Advances"
owed to it and any "Note" or "Notes" held by it under (and as each such term is
defined in) the Three-Year Agreement), (ii) except in the case of an assignment
to a Person that, immediately prior to such assignment, was a Lender or an
assignment of all of a Lender's rights and obligations under this Agreement, the
amount of the Commitment of the assigning Lender being assigned pursuant to each
such assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event be less than $10,000,000 or an
integral multiple of $1,000,000 in excess thereof, (iii) each such assignment
shall be to an Eligible Assignee, and (iv) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance, together with any Note subject to such
assignment and a processing and recordation fee of $3,000. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, (x) the assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, have the rights and
obligations of a Lender hereunder and (y) the Lender assignor thereunder shall,
to the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto).

                                       40


            (b) By executing and delivering an Assignment and Acceptance, the
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than as provided
in such Assignment and Acceptance, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of, or the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement, together with copies of
the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (v) such assignee confirms that it is an
Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers and discretion
under this Agreement as are delegated to the Agent by the terms hereof, together
with such powers and discretion as are reasonably incidental thereto; and (vii)
such assignee agrees that it will perform in accordance with their terms all of
the obligations that by the terms of this Agreement are required to be performed
by it as a Lender.

            (c) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Agent shall, if
such Assignment and Acceptance has been completed and is in substantially the
form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record
the information contained therein in the Register and (iii) give prompt notice
thereof to the Borrower. Within five Business Days after the Borrower's receipt
of such notice, if requested by the applicable Lender, the Borrower, at its own
expense, shall execute and deliver to the Agent in exchange for the surrendered
Note a new Note to the order of such Eligible Assignee in an amount equal to the
Commitment assumed by it pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained a Commitment hereunder, if requested by such
assigning Lender, a new Note to the order of the assigning Lender in an amount
equal to the Commitment retained by it hereunder. Such new Note or Notes shall
be in an aggregate principal amount equal to the aggregate principal amount of
such surrendered Note or Notes, shall be dated the effective date of such
Assignment and Acceptance and shall otherwise be in substantially the form of
Exhibit A hereto.

            (d) The Agent shall maintain at its address referred to in Section
8.02 a copy of each Assignment and Acceptance delivered to and accepted by it
and a register for the recordation of the names and addresses and Commitment of,
and principal amount of Revolving Credit Advances owing to, each Lender from
time to time (the "Register"). The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Borrower, the Agent
and the Lenders may treat each Person whose name is recorded in the

                                       41


Register as a Lender hereunder for all purposes of this Agreement. The Register
shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

            (e) Each Lender may sell participations to one or more banks or
other entities (other than the Borrower or any of its Affiliates) in or to all
or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Commitment, the Revolving Credit
Advances owing to it and any Note or Notes held by it); provided, however, that
(i) such Lender's obligations under this Agreement (including, without
limitation, its Commitment to the Borrower hereunder) shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations, (iii) such Lender shall remain the owner of
such Revolving Credit Advances for all purposes of this Agreement, (iv) the
Borrower, the Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and (v) no participant under any such
participation shall have any right to approve any amendment or waiver of any
provision of this Agreement or any Note, or any consent to any departure by the
Borrower therefrom, except to the extent that such amendment, waiver or consent
would (A) reduce the principal of, or interest on, the Revolving Credit Advances
or any fees or other amounts payable hereunder, or (B) increase the Commitments,
in each case to the extent subject to such participation, or postpone any date
fixed for any payment of principal of, or interest on, the Revolving Credit
Advances or any fees or other amounts payable hereunder, in each case to the
extent subject to such participation. Each participant shall be entitled to the
benefits and subject to the exclusions, in each case, as if it were a Lender, of
Sections 2.10, 2.11 and 2.13 to the same extent as if it were a Lender and had
acquired its interest under this Agreement by an assignment made pursuant to
this Section 8.07, provided, however, that (i) such participant complies with
the requirements of Section 2.13(e) and (ii) in no event shall the Borrower be
obligated to make any payment with respect to such Sections that is greater than
the amount that the Borrower would have otherwise made had no participations
been sold under this Section 8.07(e).

            (f) Any Lender may, in connection with any assignment, designation
or participation or proposed assignment, designation or participation pursuant
to this Section 8.07, disclose to the assignee, designee or participant or
proposed assignee, designee or participant, any information relating to the
Borrower furnished to such Lender by or on behalf of the Borrower; provided
that, prior to any such disclosure, the assignee, designee or participant or
proposed assignee, designee or participant shall agree to preserve the
confidentiality of any Confidential Information relating to the Borrower
received by it from such Lender.

            (g) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time (i) create a security interest in all or a portion of
its rights under this Agreement (including, without limitation, the Revolving
Credit Advances owing to it and the Note or Notes held by it) in favor of any
Federal Reserve Bank in accordance with Regulation A of the Board of Governors
of the Federal Reserve System or (ii) with notice to the Agent and the Borrower,
assign all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the
Revolving Credit Advances owed to it and the Note or Notes held by it) to any
Lender or any Affiliate of any Lender.

                                       42


            (h) Notwithstanding anything to the contrary contained herein, any
Lender (a "Designating Lender") may grant to one or more special purpose funding
vehicles (each an "SPV"), identified as such in writing from time to time by the
Designating Lender to the Agent and the Borrower, the option to provide to the
Borrower all or any part of any Revolving Credit Advance that such Designating
Lender would otherwise be obligated to make to the Borrower pursuant to this
Agreement; provided that (i) nothing herein shall constitute a commitment by any
SPV to make any Revolving Credit Advance, (ii) if an SPV elects not to exercise
such option or otherwise fails to provide all or any part of such Revolving
Credit Advance, the Designating Lender shall be obligated to make such Revolving
Credit Advance pursuant to the terms hereof, (iii) the Designating Lender shall
remain liable for any indemnity or other payment obligation with respect to its
Commitment hereunder and (iv) no SPV or Designating Lender shall be entitled to
receive any greater amount under this Agreement than the Designating Lender
would have been entitled to receive had the Designating Lender not otherwise
granted such SPV the option to provide any Revolving Credit Advance to the
Borrower. The making of a Revolving Credit Advance by an SPV hereunder shall
utilize the Commitment of the Designating Lender to the same extent, and as if,
such Revolving Credit Advance were made by such Designating Lender.

            (i) Each party hereto hereby acknowledges and agrees that no SPV
shall have the rights of a Lender hereunder, such rights being retained by the
applicable Designating Lender. Accordingly, and without limiting the foregoing,
each party hereby further acknowledges and agrees that no SPV shall have any
voting rights hereunder and that the voting rights attributable to any Revolving
Credit Advance made by an SPV shall be exercised only by the relevant
Designating Lender and that each Designating Lender shall serve as the
administrative agent and attorney-in-fact for its SPV and shall on behalf of its
SPV receive any and all payments made for the benefit of such SPV and take all
actions hereunder to the extent, if any, such SPV shall have any rights
hereunder. No additional Note shall be required to evidence the Revolving Credit
Advances or portion thereof made by an SPV; and the related Designating Lender
shall be deemed to hold its Note or Notes, if any, as administrative agent for
such SPV to the extent of the Revolving Credit Advances or portion thereof
funded by such SPV. In addition, any payments for the account of any SPV shall
be paid to its Designating Lender as administrative agent for such SPV.

            (j) Each party hereto hereby agrees that no SPV shall be liable for
any indemnity or payment under this Agreement for which a Lender would otherwise
be liable so long as, and to the extent that, the related Designating Lender
provides such indemnity or makes such payment; provided, with respect to such
agreement by the Borrower that the related Designating Lender shall not be in
breach of its obligation to make Revolving Credit Advances to the Borrower
hereunder. In furtherance of the foregoing, each party hereto hereby agrees
(which agreements shall survive the termination of this Agreement) that prior to
the date that is one year and one day after the payment in full of all
outstanding commercial paper or other senior indebtedness of any SPV, it will
not institute against, or join any other person in instituting against, such SPV
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any State thereof; provided,
with respect to such agreement by the Borrower that the related Designating
Lender shall not be in breach of its obligation to make Revolving Credit
Advances to the Borrower hereunder. Notwithstanding the foregoing, the
Designating Lender unconditionally agrees to indemnify the Borrower, the Agent

                                       43


and each Lender against all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be incurred by or asserted against the
Borrower, the Agent or such Lender, as the case may be, in any way relating to
or arising as a consequence of any such forbearance or delay in the initiation
of any such proceeding against its SPV.

            (k) In addition, notwithstanding anything to the contrary contained
in subsection 8.07(h), (i), (j) or (k) or otherwise in this Agreement, any SPV
may (i) at any time and without paying any processing fee therefor, assign or
participate all or a portion of its interest in any Revolving Credit Advances to
the Designating Lender or to any financial institutions providing liquidity
and/or credit support to or for the account of such SPV to support the funding
or maintenance of Revolving Credit Advances and (ii) disclose on a confidential
basis any non-public information relating to its Revolving Credit Advances to
any rating agency, commercial paper dealer or provider of any surety, guarantee
or credit or liquidity enhancements to such SPV. Subsection 8.07(h), (i), (j) or
(k) may not be amended without the written consent of any Designating Lender
affected thereby.

      SECTION 8.08. Confidentiality. Neither the Agent nor any Lender shall
disclose any Confidential Information to any other Person without the consent of
the Borrower, other than (a) to the Agent's or such Lender's Affiliates and
their officers, directors, employees, agents and advisors and, as contemplated
by Section 8.07(f), to actual or prospective assignees and participants, and
then only on a confidential basis, (b) as required by any law, rule or
regulation or judicial process, (c) to any rating agency when required by it,
provided that, prior to any such disclosure, such rating agency shall undertake
to preserve the confidentiality of any Confidential Information relating to the
Borrower received by it from such Lender, (d) as requested or required by any
state, federal or foreign authority or examiner regulating banks, other
financial institutions or banking, (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding relating to this Agreement
or the enforcement of rights hereunder and (f) on a confidential basis to any
Lender's direct or indirect contractual counterparties in swap agreements or to
legal counsel, accountants and other professional advisors to such
counterparties.

      SECTION 8.09. Governing Law. This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New
York.

      SECTION 8.10. Execution in Counterparts; Integration. This Agreement may
be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement. This Agreement and any separate letter agreement
with respect to fees payable to the Agent or confidential information (the
latter of which shall apply solely to information provided prior to the date
hereof) constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings,
oral or written, relating to the subject matter hereof.

                                       44


      SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties hereto hereby
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any New York State court or federal court of the
United States of America sitting in New York City, and any appellate court from
any thereof, in any action or proceeding arising out of or relating to this
Agreement or the Notes, or for recognition or enforcement of any judgment, and
each of the parties hereto hereby irrevocably and unconditionally agrees that
all claims in respect of any such action or proceeding may be heard and
determined in any such New York State court or, to the extent permitted by law,
in such federal court. Each of the parties hereto agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law. Nothing in this Agreement shall affect any right that any party may
otherwise have to bring any action or proceeding relating to this Agreement or
the Notes in the courts of any jurisdiction.

            (b) Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement or the Notes
in any New York State or federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

      SECTION 8.12. Waiver of Jury Trial. Each of the Borrower, the Agent and
the Lenders hereby irrevocably waives all right to trial by jury in any action,
proceeding or counterclaim (whether based on contract, tort or otherwise)
arising out of or relating to this Agreement or the Notes or the actions of the
Agent or any Lender in the negotiation, administration, performance or
enforcement thereof.

      SECTION 8.13. Consent.

            (a) The Borrower has requested that, notwithstanding anything to the
contrary in the Existing Credit Agreement, the Agent and the requisite number of
Lenders (as defined in the Existing Credit Agreement) under Section 8.01 of the
Existing Credit Agreement permit the Borrower and certain of the Lenders (as
defined in the Existing Credit Agreement) to amend and restate the Existing
Credit Agreement as this Agreement; provided that concurrently with the
effectiveness of this Agreement each Lender (as defined in the Existing Credit
Agreement) that is not party to this Agreement (each an "Exiting Lender") shall
be released from all of its respective rights (other than contingent indemnity
rights) and obligations under the Existing Credit Agreement as of the Effective
Date (which rights and obligations shall, without any representation or warranty
from any Exiting Lender and without recourse to any Exiting Lender, thereafter
be re-evidenced by the rights and obligations of the Lenders party to this
Agreement) and each Exiting Lender shall have received an amount equal to its
respective Loans outstanding under the Existing Credit Agreement from the
Lenders party to this Agreement. Subject to the provisions of the preceding
sentence, the Agent and the requisite number of Lenders (as defined in the
Existing Credit Agreement) under Section 8.01 of the Existing Credit Agreement
hereby consent to the amendment and restatement of the Existing Credit Agreement
as this Agreement.

            (b) The Borrower, the Lenders (as defined in the Three-Year Credit
Agreement) and the Agent agree that, upon (i) the execution and delivery of this
Agreement by

                                       45


each of the parties hereto and (ii) the satisfaction (or waiver by the
aforementioned parties) of the conditions precedent set forth in Section 3.01,
the unused portions of the respective Commitments of the Lenders (as such terms
are defined in the Three-Year Credit Agreement) under the Three-Year Credit
Agreement shall be and hereby are terminated ratably in part in the aggregate
amount of $81,250,000.00 and to the extent any such termination of the
Commitments of the Lenders (as such terms are defined in the Three-Year Credit

information that identifies each person or entity that opens an account,
including any deposit account, treasury management account, loan, other
extension of credit, or other financial services product. What this means for
the Borrower: When the Borrower opens an account, the Agent and the Lenders will
ask for the Borrower's name, tax identification number, business address, and
other information that will allow the Agent and the Lenders to identify the
Borrower. The Agent and the Lenders may also ask to see the Borrower's legal
organizational documents or other identifying documents.

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

      "Level I Status" exists at any date if, on such date, the Borrower's
Moody's Rating, is A3 or better or the Borrower's S&P Rating is A- or better.

      "Level II Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status and (ii) the Borrower's Moody's Rating is
Baa1 or better or the Borrower's S&P Rating is BBB+ or better.

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

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

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

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



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

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

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

            The Applicable Margin, Applicable Utilization Fee and Applicable
Percentage shall be determined in accordance with the foregoing table based on
the Borrower's Status as determined from its then-current Moody's and S&P
Ratings. The credit rating in effect on any date for the purposes of this
Schedule is that in effect at the close of business on such date. If at any time
the Borrower does not have both a Moody's Rating and an S&P Rating, Level VI
Status shall exist.

            Except as specifically provided above in this Schedule, in the event
that a split occurs between the two ratings, then the rating corresponding to
the higher of the two ratings shall apply. However, if the split is greater than

            (iv)  The By-Laws of each of the Borrowers and all amendments
      thereto (the "By-Laws").

            (v)   Certificates from the State of Michigan attesting to the
      continued corporate existence and good standing of each of the Borrowers.

In addition, I have examined the originals, copies certified to my satisfaction,
of such other corporate records of each Borrower, certificates of public
officials and of officers of each Borrower, and agreements, instruments and
other documents, as I have deemed necessary as a basis for the opinions
expressed below. As to questions of fact material to such opinions, I have, when
relevant facts were not independently established by me, relied upon
certificates of public officials. I have assumed the due execution and delivery,
pursuant to due authorization, of each of the Credit Agreements by the Lenders
and the applicable Agent.

            My opinions expressed below are limited to the law of the State of
Michigan and the federal law of the United States.

            Based upon the foregoing and upon such investigation as I have
deemed necessary, I am of the following opinion:

            1. Each of the Borrowers is a corporation duly organized, validly
existing and in good standing under the laws of the State of Michigan.

            2. The execution, delivery and performance by each Borrower of the
Loan Documents to which it is party, and the consummation of the transactions
contemplated thereby, are within such Borrower's corporate powers, have been
duly authorized by all necessary corporate action, and do not contravene (i) the
Charters or the By-Laws of such Borrower or (ii) any law, rule or regulation
applicable to such Borrower, or (iii) any contractual restriction binding on or
affecting such Borrower.

            3. No consent, authorization or approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body or any
other third party is required for the due execution, delivery, recordation,
filing or performance by each Borrower of the Loan Documents to which it is a
party, except in the case of DECO, the order of the Federal Energy Regulatory
Commission, which has been obtained.



            4. Each respective Credit Agreement has been, and each of the
respective Notes when delivered will have been, duly executed and delivered on
behalf of the Borrower thereto.

            5. Except as may have been disclosed to you in the SEC Reports, to
the best of my knowledge (after due inquiry) there are no pending or overtly
threatened actions or proceedings affecting any Borrower or any of its
respective Significant Subsidiaries before any court, governmental agency or
arbitrator that (i) could be reasonably likely to have a Material Adverse Effect
or (ii) purport to affect the legality, validity, or enforceability of any Loan
Documents to which such Borrower is a party or the consummation of the
transactions contemplated thereby.

            6. In a properly presented case, a Michigan court or a federal court
sitting in the State of Michigan applying Michigan choice of law rules should
give effect to the choice of law provisions of the Loan Documents and should
hold that such Loan Documents are to be governed by the laws of the State of New
York rather than the laws of the State of Michigan. In rendering the foregoing
opinion, I note that by their terms the Loan Documents expressly select New York
law as the laws governing their interpretation and that the Loan Documents
governed by New York law were delivered by the parties thereto to the Agent in
New York. The choice of law provisions of the Loan Documents are not voidable
under the laws of the State of Michigan.

            7. If, despite the provisions of Section 8.09 of each of the Credit
Agreements wherein the parties thereto agree that the Loan Documents shall be
governed by, and construed in accordance with, the laws of the State of New
York, a court of the State of Michigan or a federal court sitting in the State
of Michigan were to hold that the Loan Documents are governed by, and to be
construed in accordance with the laws of the State of Michigan, the respective
Loan Documents would be, under the laws of the State of Michigan, legal, valid
and binding obligations of the applicable Borrower, enforceable against such
Borrower in accordance with their respective terms.

            8. Neither the Borrowers nor any of their Subsidiaries is an
"investment company," or an "affiliated person" of, or "promoter" or "principal
underwriter" for, an "investment company," as such terms are defined in the
Investment Company Act of 1940, as amended; DECO is a "public utility company"
and a "subsidiary company" of DTE, which is a "holding company" as such terms
are defined in the Public Utility Holding Company Act of 1935, as amended (the
"1935 Act"), and such "holding company" and DECO are currently exempt from the
provisions of the 1935 Act (except Section 9 thereof); and MichCon is a "public
utility company" and a "subsidiary company" of MichCon Holdings, Inc., which is
a "holding company" and a "subsidiary company" of DTE Enterprises, Inc., which
is a "holding company" and a "subsidiary company" of DTE, as such terms are
defined in the 1935 Act, and such



"holding companies" and MichCon are currently exempt from the provisions of the
1935 Act (except Section 9 thereof);

            The opinions set forth above are subject to the following
qualifications:

            (a) My opinion in paragraph 7 above as to enforceability is subject
            to the effect of any applicable bankruptcy, insolvency, fraudulent
            conveyance, reorganization, moratorium or laws affecting creditors'
            rights generally.

            (b) My opinion in paragraph 7 above as to enforceability is subject
            to the effect of general principles of equity, including, without
            limitation, concepts of materiality, reasonableness, good faith and
            fair dealing (regardless of whether considered in a proceeding in
            equity or at law).

            (c) I express no opinion as to participation and the effect of the
            law of any jurisdiction other than the State of Michigan wherein any
            Lender may be located or wherein enforcement of the Loan Documents
            may be sought that limits the rates of interest legally chargeable
            or collectible.

            I am a member of the Bar of the State of Michigan, and do not
express any opinion concerning any law other than the law of the State of
Michigan and the federal laws of the United States of America.

            This opinion letter is rendered to you in connection with the
above-described transaction. This opinion letter may not be relied upon by you
for any other purpose, or relied upon by any other person or entity without my
prior written consent (provided, that this opinion letter may be furnished to

Agreements and a Note, if any, solely for the purpose of such assignment or
participation, subject to the assumptions, limitations and qualifications, set
forth herein, without any prior written consent). I undertake no duty to inform
you or any assignee or participant of events occurring subsequent to the date
hereof.

To each of the Lenders
listed on Schedule A hereto

DTE Energy Company
The Detroit Edison Company
Michigan Consolidated Gas Company

Ladies and Gentlemen:

            This opinion is delivered to you pursuant to (i) Section 3.01(g)(v)
of the Amended and Restated Five-Year Credit Agreement, dated as of October 15,
2004, among DTE Energy Company ("DTE"), the financial institutions from time to
time parties thereto (the "DTE Lenders"), and Citibank, N.A., as agent for said
DTE Lenders (the "DTE Credit Agreement"), (ii) Section 3.01(g)(v) of the Amended
and Restated Five-Year Credit Agreement, dated as of October 15, 2004, among The
Detroit Edison Company ("DECO"), the financial institutions parties thereto (the
"DECO Lenders") and Barclays Bank PLC, as agent for said DECO Lenders (the "DECO
Credit Agreement"), and (iii) Section 3.01(g)(v) of the Amended and Restated
Five-Year Credit Agreement, dated as of October 15, 2004, among Michigan
Consolidated Gas Company ("MichCon", and together with DTE and DECO, the
"Borrowers"), the financial institutions parties thereto (the "MichCon Lenders",
and together with the DTE Lenders and the DECO Lenders, the "Lenders") and Bank
One, NA (Main Office - Chicago), as agent for said MichCon Lenders (the "MichCon
Credit Agreement", and together with the DTE Credit Agreement and the DECO
Credit Agreement, the "Credit Agreements"). Terms used herein which are defined
in each Credit Agreement shall have the respective meanings set forth in each
Credit Agreement, unless otherwise defined herein.



            We have acted as special counsel to the Borrowers in connection with
the preparation, execution and delivery of the Credit Agreements.

            In connection with this opinion we have examined a copy of each
Credit Agreement signed by each of the parties thereto. We have also examined
the originals, or duplicates or certified or conformed copies, of such records,
agreements, instruments and other documents and have made such other
investigations as we have deemed relevant and necessary in connection with the
opinions expressed herein. As to questions of fact material to this opinion, we
have relied upon certificates of public officials and of officers and
representatives of the Borrowers. In addition, we have examined, and have relied
as to matters of fact upon, the representations made in the Credit Agreements.

            In rendering the opinions set forth below, we have assumed the
genuineness of all signatures, the legal capacity of natural persons, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as duplicates or certified
or conformed copies, and the authenticity of the originals of such latter
documents. We have assumed without independent investigation that (a) the Loan
Documents have been duly authorized, executed and delivered by the Borrowers,
(b) the Borrowers have been duly incorporated and are validly existing and in
good standing under the laws of their jurisdictions of incorporation and have
the corporate power and authority to execute, deliver and perform their
obligations under the Loan Documents, (c) the execution, delivery and
performance of the Loan Documents by each of the Borrowers to which it is a
party (i) have been duly authorized by all necessary corporate action on their
part, (ii) do not contravene their certificates of incorporation or by-laws or,
except as set forth in paragraph 2 below, violate, or require any consent not
obtained under, any applicable law or regulation or any order, writ, injunction
or decree of any court or other governmental authority binding upon it and (iii)
do not violate, or require any consent not obtained under, any contractual
obligation applicable to or binding upon it, and (d) the Credit Agreements
constitute the valid and legally binding obligation of the applicable Agent and
the applicable Lenders.

            Based upon and subject to the foregoing, and subject to the
assumptions, qualifications and comments set forth herein, we are of the opinion
that:

      1. Each of the respective Credit Agreements is the legal, valid and
binding obligation of the applicable Borrower enforceable against such Borrower
in accordance with its respective terms. Each of the respective Notes issued on
the date hereof, if any, is the legal, valid and binding obligation of the
applicable Borrower, enforceable against such Borrower in accordance with its
respective terms.



      2. The execution, delivery and performance by each of the Borrowers of the
Loan Documents to which it is a party will not violate any Federal or New York
statute or any rule or regulation issued pursuant to any Federal or New York
statute.

            Our opinion in paragraph 1 above is subject to (i) the effect of any
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or laws affecting creditors' rights generally, (ii) general equitable
principles (regardless of whether enforcement is sought in a proceeding in
equity or at law) and (iii) an implied covenant of good faith and fair dealing.

            We express no opinion with respect to: (a) the effect of any
provision of the Loan Documents that is intended (i) to establish any standard
as the measure of the performance by any party thereto of such party's
obligations of good faith, diligence, fair dealing, reasonableness or care or
(ii) to permit modification thereof only by means of an agreement in writing
signed by the parties thereto; (b) the effect of any provision of the Loan
Documents insofar as it provides that any Person purchasing a participation from
a Lender or other Person may exercise set-off or similar rights with respect to
such participation or that any Lender or other Person may exercise set-off or
similar rights other than in accordance with applicable law; (c) the effect of
any provision of the Loan Documents imposing penalties or forfeitures; (d) the
effect of any provision of the Loan Documents relating to indemnification or
exculpation in connection with violations of any securities laws or relating to
indemnification, contribution or exculpation in connection with willful,
reckless or criminal acts or gross negligence of the indemnified or exculpated
Person or the Person receiving contribution; (e) any provision of the Loan
Documents which purports to provide for a waiver by the Borrowers of any
immunity, defense or right which may be available to the Borrowers; and (f) any
provision of the Loan Documents which purports to establish an evidentiary
standard for determinations by any Person.

            In connection with the provisions of the Credit Agreements whereby
the Borrowers submit to the jurisdiction of the courts of the United States of
America located in the State of New York, we note the limitations of 28 U.S.C.
Sections 1331 and 1332 on subject matter jurisdiction of the Federal courts. In
connection with the provisions of the Credit Agreement that relate to forum
selection (including, without limitation, any waiver of any objection to venue
or any objection that a court is an inconvenient forum), we note that under
NYCPLR Section 510, a New York State court may have discretion to transfer the
place of trial, and under 28 U.S.C. Section 1404(a), a United States District
Court has discretion to transfer an action from one Federal court to another.

            We are members of the Bar of the State of New York, and we do not
express any opinion concerning any law other than Federal law and the law of the
State of New York.



            This opinion letter is rendered to you in connection with the
above-described transactions. This opinion letter may not be relied upon by you
for any other purpose, or relied upon by any other person or entity without our
prior written consent (provided, that this opinion Letter may be furnished to

Agreements and a Note, if any, solely for the purpose of such assignment or
participation, subject to the assumptions, limitations and qualifications set
forth herein without our prior written consent). We undertake no duty to inform
you or any assignee or participant of events occurring subsequent to the date
hereof.

                                            Very truly yours,



                                                                      Schedule A
