        ARTICLE II: AMOUNTS AND TERMS OF THE REVOLVING CREDIT ADVANCES

                SECTION 2.01.   The Revolving Credit Advances. Each Lender
severally agrees, on the terms and conditions hereinafter set forth, to make
Revolving Credit Advances to the Borrower from time to time on any Business Day
during the period from the Effective Date until the Revolver Termination Date in
an aggregate amount not to exceed at any time outstanding the amount set forth
opposite such Lender's name on Schedule 1 hereto or, if such Lender has entered
into any Assignment and Acceptance, set forth for such Lender in the Register
maintained by the Agent pursuant to Section 8 .07(d), as such amount may be
reduced pursuant to Section 2.04 (such Lender's "Commitment"). Each Borrowing
shall be in an aggregate amount of $5,000,000 or an integral multiple of
$1,000,000 in excess thereof and shall consist of Revolving Credit Advances of
the same Type made on the same day by the Lenders ratably according to their
respective Commitments. Within the limits of each Lender's Commitment, the
Borrower may borrow under this Section 2.01, prepay pursuant to Section 2.09 and
reborrow under this Section 2.01.

                SECTION 2.02.   Making the Revolving Credit Advances. (a) Each
Borrowing shall be made on notice, given not later than 10:00 A.M. (Chicago
time) on the third Business Day prior to the date of the proposed Borrowing in
the case of a Borrowing consisting of Eurodollar Rate Advances, or 9:00 A.M.
(Chicago time) the Business Day of the proposed



                                       12
<PAGE>

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, or telecopier or telex
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, and (iv) in the case
of a Borrowing consisting of Eurodollar Rate Advances, initial Interest Period
for each such Revolving Credit Advance. 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
at the Agent's address referred to in Section 8.02.

        (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) the Eurodollar Rate
Advances may not be outstanding as part of more than ten separate Borrowings.

        (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 (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds 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.



                                       13
<PAGE>

        (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 Revolving Loan 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 all
Revolving Credit Advances hereunder exceeds thirty-three percent (33%) of the
aggregate amount of all Commitments then in effect on such date (or, if the
Commitments have been terminated, the aggregate amount of all 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 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 Revolving Loan 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




                                       14
<PAGE>

        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
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) 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.



                                       15
<PAGE>

        (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 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,

                (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 Eurodollar Rate 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



                                       16
<PAGE>

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: (i) 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 the Securities Exchange Act of 1934), directly or indirectly,
of Voting Stock of the Borrower (or other securities convertible into such
Voting Stock) representing 20% or more of the combined voting power of all
Voting Stock of the Borrower; or (ii) any Person or two or more Persons acting
in concert (other than DTE Energy or any of its Subsidiaries) shall have
acquired by contract or otherwise, or shall have entered into a contract or
arrangement that, upon consummation, will result in its or their acquisition of
the power to exercise, directly or indirectly, a controlling influence over the
management or policies 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 (i) Taxes or Other
Taxes (as to which Section 2.13 shall govern) and (ii) changes in the basis of
taxation of overall net income or overall gross income by the United States or
by the foreign jurisdiction or state under the laws of which such Lender is
organized or has its Applicable Lending Office or any political subdivision
thereof), 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



                                       17
<PAGE>

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
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. 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



                                       18
<PAGE>

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 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) 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, taxes
imposed on its overall net income, and franchise taxes imposed on it in lieu of
net income taxes, 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, in the case of each Lender, taxes imposed on its overall net income, and
franchise taxes imposed on it in lieu of net income taxes, 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



                                       19
<PAGE>

liabilities in respect of payments hereunder or under the Notes being
hereinafter referred to as "Taxes"). 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, (i) the sum payable shall be increased as may
be necessary so that after making all required deductions (including deductions
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)     In addition, 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, performing under, or otherwise
with respect to, this Agreement or the Notes (hereinafter referred to as "Other
Taxes").

        (c)     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 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-8BEW or W-8ECI, as appropriate, or any successor or other form prescribed
by the Internal Revenue Service, certifying that such Lender is exempt from or
entitled to a reduced rate of United States withholding tax on payments pursuant
to this Agreement or the Notes. If the forms provided by a Lender at the time
such Lender first becomes a party to this Agreement indicates a United States
interest withholding tax rate in excess of zero, withholding tax at such rate
shall be considered excluded from Taxes unless and until such Lender provides
the appropriate forms certifying that a lesser rate applies, whereupon
withholding tax at such lesser rate only shall be



                                       20
<PAGE>

considered excluded from Taxes for periods governed by such form; provided,
however, that, if at the date of the Assignment and Acceptance pursuant to which
a Lender assignee becomes a party to this Agreement, the Lender assignor was
entitled to payments under subsection (a) in respect of United States
withholding tax with respect to interest paid at such date, then, to such
extent, the term Taxes shall include (in addition to withholding taxes that may
be imposed in the future or other amounts otherwise includable in Taxes) United
States withholding tax, if any, applicable with respect to the Lender assignee
on such date. 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 W8BEW 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.

        (f)     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.

        (g)     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 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 2.14.   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



                                       21
<PAGE>

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.   Extensions of Revolver Termination Date. No
earlier than 45 days and no later than 30 days prior to the Revolver Termination
Date in effect at any time, the Borrower may, by written notice to the Agent,
request that such Revolver Termination Date be extended for a period of 364
days. Such request shall be irrevocable and binding upon the Borrower. The Agent
shall promptly notify each Lender of such request. If a Lender agrees, in its
individual and sole discretion, to so extend its Commitment (an "Extending
Lender"), it shall deliver to the Agent a written notice of its agreement to do
so no earlier than 30 days and no later than 20 days prior to such Revolver
Termination Date and the Agent shall notify the Borrower of such Extending
Lender's agreement to extend its Commitment no later than 15 days prior to such
Revolver Termination Date. The Commitment of any Lender that fails to accept or
respond to the Borrower's request for extension of the Revolver Termination Date
(a "Declining Lender") shall be terminated on the Revolver Termination Date
originally in effect (without regard to any extension by other Lenders) and on
such Revolver Termination Date the Borrower shall pay in full the principal
amount of all Revolving Credit Advances owing to such Declining Lender, together
with accrued interest thereon to the date of such payment of principal and all
other amounts payable to such Declining Lender under this Agreement. The Agent
shall promptly notify each Extending Lender of the aggregate Commitments of the
Declining Lenders. The Extending Lenders, or any of them, may offer to increase
their respective Commitments by an aggregate amount up to the aggregate amount
of the Declining Lenders' Commitments and any such Extending Lender shall
deliver to the Agent a notice of its offer to so increase its Commitment no
later than 15 days prior to such Revolver Termination Date. To the extent of any
shortfall in the aggregate amount of extended Commitments, the Borrower shall
have the right to require any Declining Lender to assign in full its rights and
obligations under this Agreement to an Eligible Assignee designated by the
Borrower and acceptable to the Agent, that agrees to accept all of such rights
and obligations (a "Replacement Lender"), provided that (i) such increase and/or
such assignment is otherwise in compliance with Section 8.07 (provided that the
$3000 processing and recording fee in respect of such assignment shall be
payable by the Borrower), (ii) such Declining Lender receives payment in full of
the principal amount of all Revolving Credit Advances owing to such Declining
Lender, together with accrued interest thereon to the date of such payment of
principal and all other amounts payable to such Declining Lender under this
Agreement, and (iii) any such increase shall be effective on the Revolver
Termination Date in effect at the time the Borrower requests such extension and
any such assignment shall be effective on the date specified by the Borrower and
agreed to by the Replacement Lender and the Agent. If Extending Lenders and
Replacement Lenders provide Commitments in an aggregate amount at least equal to
51% of the aggregate amount of the Commitments outstanding 30 days prior to the
Revolver Termination Date in effect at the time



                                       22
<PAGE>

the Borrower requests such extension, the Revolver Termination Date shall be
extended by 364 days for such Extending Lenders.

                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 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.

                ARTICLE III: CONDITIONS TO EFFECTIVENESS AND LENDING

                SECTION 3.01.   Conditions Precedent to Effectiveness of Section
2.01. Section 2.01 of this Agreement shall become effective on and as of the
date hereof (the "Effective Date"), provided that the following conditions
precedent have been satisfied on such date:

                (b)     There shall exist no action, suit, investigation,
        litigation or proceeding affecting the Borrower or any of its
        Significant Subsidiaries pending or threatened before any court,
        governmental agency or arbitrator that (i) could be reasonably likely to
        have a Material Adverse Effect other than the matters disclosed or
        contemplated in the SEC Reports (the "Disclosed Litigation") or (ii)
        purports to affect the legality, validity or enforceability of any Loan
        Document or the consummation of the transactions contemplated hereby and
        there shall have been no adverse change in the status, or financial
        effect on the Borrower or any of its Significant Subsidiaries of the
        Disclosed Litigation from that disclosed or contemplated in the SEC
        Reports.

                (c)     The Lenders shall have been given such access, as such
        Lenders have reasonably requested, to the management, records, books of
        account, contracts and properties of the Borrower and its Significant
        Subsidiaries as they shall have requested.

                (d)     All governmental and third party consents and approvals
        necessary in connection with the transactions contemplated hereby shall
        have been obtained (without the imposition of any conditions that are
        not acceptable to the Lenders) and shall remain in effect, and no law or
        regulation shall be applicable in the reasonable judgment of the Lenders
        that restrains, prevents or imposes materially adverse conditions upon
        the transactions contemplated by the Loan Documents.

                (e)     The Borrower shall have notified each Lender and the
        Agent in writing as to the proposed Effective Date.

        Agreement for which the Agent shall have made reasonable demand in
        accordance with Section 8.04 on or prior to the Effective Date.

                (g)     On the Effective Date, the following statements shall be
        true and the Agent shall have received for the account of each Lender a
        certificate signed by a duly authorized officer of the Borrower, dated
        the Effective Date, stating that:

                        (i)     The representations and warranties contained in
                Section 4.01 are correct on and as of the Effective Date, and

                        (iii)   The Borrower shall have delivered a certificate,
                substantially in form of Exhibit D hereto, signed on behalf of
                the Borrower by a Financial Officer of the Borrower.

                expressly survive the termination thereof) and all loans
                outstanding and other amounts owed to the lenders or agents
                thereunder shall have been simultaneously with the initial
                Revolving Credit Advance hereunder be paid in full.

                SECTION 3.02.   Conditions Precedent to Each Borrowing. The
obligation of each Lender to make a Revolving Credit Advance on the occasion of
each Borrowing shall be subject to the conditions precedent that the Effective
Date shall have occurred and on the date of such Borrowing (a) the following
statements shall be true (and each of the giving of the applicable Notice of
Borrowing and the acceptance by the Borrower of the proceeds of such Borrowing
shall constitute a representation and warranty by the Borrower that on the date
of such Borrowing such statements are true):

                (i)     the representations and warranties contained in Section
        4.01 (other than the representations and warranties contained in the
        last sentence of Section 4.01(e) and in Section 4.01(f)) are correct on

        though made on and as of such date, and

                (ii)    no event has occurred and is continuing, or would result

documents as any Lender through the Agent may reasonably request.

                SECTION 3.03.   Determinations Under Section 3.01. For purposes
of determining compliance with the conditions specified in Section 3.01, each
Lender shall be deemed to have consented to, approved or accepted or to be
satisfied with each document or other matter required thereunder to be consented

<PAGE>

this Agreement shall have received notice from such Lender prior to the date
that the Borrower, by notice to the Lenders, designates as the proposed
Effective Date, specifying its objection thereto. The Agent shall promptly
notify the Lenders of the occurrence of the Effective Date.

                ARTICLE IV: REPRESENTATIONS AND WARRANTIES

                SECTION 4.01.   Representations and Warranties of the Borrower.
The Borrower represents and warrants as follows:

                (a)     The Borrower is a corporation duly organized, validly
        existing and in good standing under the laws of the jurisdiction of its
        incorporation.

                (b)     The execution, delivery and performance by the Borrower
        of the Loan Documents to which it is a party, and the consummation of
        the transactions contemplated hereby and thereby, are within the
        Borrower's corporate powers, have been duly authorized by all necessary
        corporate action, and do not contravene (i) the Borrower's charter or
        by-laws or (ii) law or any contractual restriction binding on or
        affecting the Borrower.

                (c)     No 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 and
        performance by the Borrower of this Agreement, the Notes or any other
        Loan Document to which it is a party.

                (d)     This Agreement has been, and each of the Notes and each
        of the other Loan Documents to which it is a party when delivered
        hereunder will have been, duly executed and delivered by the Borrower.
        This Agreement is, and each of the Notes and each of the other Loan
        Documents to which it is a party when delivered hereunder will be, the
        legal, valid and binding obligation of the Borrower enforceable against
        the Borrower in accordance with their respective terms, subject to the
        effect of any applicable bankruptcy, insolvency, reorganization,
        moratorium or similar law affecting creditors rights generally.

                (e)     The Audited Statements of the Borrower and the Unaudited
        Statements of the Borrower, copies of each of which have been furnished
        to each Lender, fairly present, subject in the case of Unaudited
        Statements to normal year-end audit adjustments, the Consolidated
        financial condition, results of operations and cash flows of the
        relevant Persons and entities, as at the dates and for the periods
        therein indicated, all in accordance with generally accepted accounting
        principles consistently applied. Since June 30, 2001, there has been no
        Material Adverse Change, except as shall have been disclosed or
        contemplated in the SEC Reports.

                (f)     There is no pending or threatened action, suit,
        investigation, litigation or proceeding, including, without limitation,
        any Environmental Action, affecting the Borrower or any of the
        Significant Subsidiaries before any court, governmental agency or
        arbitrator that (i) could be reasonably likely to have a Material
        Adverse Effect (other than the Disclosed Litigation) or (ii) purports to
        affect the legality, validity or enforceability of this Agreement, any
        Note or any other Loan Document or the consummation of the



                                       26
<PAGE>

        transactions contemplated hereby and there has been no adverse change in
        the status of any Disclosed Litigation, or its financial effect on the
        Borrower or any of the Significant Subsidiaries from that disclosed or
        contemplated in the SEC Reports.

                (g)     The operations and properties of the Borrower and each
        of the Significant Subsidiaries comply in all material respects with all
        applicable Environmental Laws and Environmental Permits, all past
        non-compliance with such Environmental Laws and Environmental Permits
        has been resolved without ongoing obligations or costs, except as
        disclosed or contemplated in the SEC Reports, and no circumstances exist
        that could be reasonably likely to (i) form the basis of an
        Environmental Action against the Borrower or any of the Significant
        Subsidiaries or any of their properties that could have a Material
        Adverse Effect or (ii) cause any such property to be subject to any

        reasonably likely to incur liability in excess of $25,000,000
        individually or in the aggregate as a result of one or more of the
        following: (i) the occurrence of any ERISA Event; (ii) the partial or
        complete withdrawal of the Borrower or any of its ERISA Affiliates from
        a Multiemployer Plan; or (iii) the reorganization or termination of a
        Multiemployer Plan; or

                (j)     The Borrower and its Subsidiaries, on a Consolidated
        basis, shall at any time cease to:

                        (i)     Maintain a ratio of Consolidated EBITDA to cash
                interest payable on all Debt (excluding (A) all Nonrecourse Debt
                of the Borrower and its Subsidiaries, and (B) Excluded Hedging
                Debt) of not less than 2:1 for each twelve-month period ending
                on the last day of September, December, March and June of each
                year, or

                        (ii)    Maintain a ratio of Consolidated Debt (excluding
                (A) Debt outstanding pursuant to the issuance of Debt with
                maturities of no more than 365 days, (B) all Nonrecourse Debt of
                the Borrower and its Subsidiaries, and (C) Excluded Hedging
                Debt) to Capitalization of not greater than .55:1; or

                (k)     any provision of any of the Loan Documents after
        delivery thereof pursuant to Section 3.01 shall for any reason cease to
        be valid and binding on or enforceable against the Borrower, or the
        Borrower shall so state in writing;



                                       33

then, and in any such event, the Agent (i) shall at the request, or may with the
consent, of the Required Lenders, by notice to the Borrower, declare the
obligation of each Lender to make Revolving Credit Advances to be terminated,
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
interest and all such amounts shall automatically become and be due and payable,
without presentment, demand, protest or any notice of any kind, all of which are
hereby expressly waived by the Borrower.

                             ARTICLE VII: THE AGENT

                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



                                       34
<PAGE>

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.

                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.



                                       35
<PAGE>

                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.

                           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, 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) except as provided in Section
2.16, postpone any date fixed for any payment of principal of, or interest on,

(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. All notices and other
communications provided for hereunder shall be in writing (including telecopier,
telegraphic or telex communication) and mailed, telecopied, telegraphed, telexed
or delivered, if to the Borrower, at its address at 2000 2nd Avenue, Detroit, MI
48226, Attention: Treasurer; if to any Initial Lender, at its Domestic Lending

Borrower or the Agent, at such other address as shall be designated by such
party in a written notice to the other parties and, as to each other party, at
such other address as shall be designated by such party in a written notice to
the Borrower and the Agent. All such notices and communications shall, when
mailed, telecopied,

<PAGE>

telegraphed or telexed, be effective when deposited in the mails, telecopied,
delivered to the telegraph company or confirmed by telex answerback,
respectively, except that notices and communications to the Agent pursuant to
Article II, III or VII shall not be effective until received by the Agent.
Delivery by telecopier of an executed counterpart of any amendment or waiver of
any provision of this Agreement or the Notes or of any Exhibit hereto to be
executed and delivered hereunder shall be effective as delivery of a manually
executed counterpart thereof.

                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 this Agreement, the Notes, each other 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 this Agreement, the Notes 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 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 Notes, this Agreement, the other 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



                                       37
<PAGE>

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 Notes, this Agreement, the other 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 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



                                       38
<PAGE>

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 (for so long as no Default has occurred and is
continuing) the Borrower (which consent shall not be unreasonably withheld)
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, (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).

        (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



                                       39
<PAGE>

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 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



                                       40
<PAGE>

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 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 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 of
its Affiliates.

        (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
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

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,

undertake to preserve the confidentiality of any Confidential Information
relating to the Borrower received by it from such Lender and (d) as requested or
required by any state, federal or foreign authority or examiner regulating banks

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.

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.

                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 or the
Borrower's S&P Rating is BBB- or better.

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

<PAGE>

                "Status" means Level I Status, Level II Status, Level III
Status, Level IV Status or Level V 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 Rating and S&P
Rating. 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 V
Status shall exist.

                In the event that a split occurs between the two ratings, then
the Status corresponding to the lower of the two ratings shall apply. However,
if the split is greater than one level, then the pricing shall be based upon the
Status one level above the Status corresponding to the lower of the two ratings.

Agreement are used herein with the same meaning.

                The "Assignor" and the "Assignee" referred to on Schedule I
hereto agree as follows:

                1.      The Assignor hereby sells and assigns to the Assignee,

                2.      The Assignor (i) represents and warrants that it is the

hereto and the Assignor in an amount equal to the Commitment retained by the
Assignor under the Credit Agreement, respectively, as specified on Schedule 1
hereto.

                3.      The Assignee (i) confirms that it has received a copy of
the Credit Agreement, together with copies of the financial statements referred
to in Section 4.01 thereof and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
this Assignment and Acceptance; (ii) agrees that it will, independently and
without reliance upon the Agent, the Assignor 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
the Credit Agreement; (iii) confirms that it is an Eligible Assignee; (iv)
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers and discretion under the Credit Agreement as are
delegated to the Agent by the terms thereof, together with such powers and
discretion as are


                                       11

reasonably incidental thereto; (v) agrees that it will perform in accordance
with their terms all of the obligations that by the terms of the Credit
Agreement are required to be performed by it as a Lender; and (vi) attaches any
U.S. Internal Revenue Service forms required under Section 2.13 of the Credit
Agreement.

                4.      Following the execution of this Assignment and
Acceptance, it will be delivered to the Agent for acceptance and recording by
the Agent. The effective date for this Assignment and Acceptance (the "Effective
Date") shall be the date of acceptance hereof by the Agent, unless otherwise
specified on Schedule 1 hereto.

                5.      Upon such acceptance and recording by the Agent, as of
the Effective Date, (i) the Assignee shall be a party to the Credit Agreement
and, to the extent provided in this Assignment and Acceptance, have the rights
and obligations of a Lender thereunder and (ii) the Assignor shall, to the
extent provided in this Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Credit Agreement.

                6.      Upon such acceptance and recording by the Agent, from
and after the Effective Date, the Agent shall make all payments under the Credit
Agreement and the Notes in respect of the interest assigned hereby (including,
without limitation, all payments of principal, interest, facility fees and the
Utilization Fee with respect thereto) to the Assignee. The Assignor and Assignee
shall make all appropriate adjustments in payments under the Credit Agreement

                                              OPINION OF COUNSEL TO THE BORROWER

                                        [Date]

To each of the Lenders set forth
in Schedule A hereto

DTE Energy Company
The Detroit Edison Company
Michigan Consolidated Gas Company

Ladies and Gentlemen:

                This opinion is furnished to you pursuant to (i) Section
3.01(h)(v) of the Credit Agreement, dated as of November 7, 2001, 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,
Barclays Bank PLC and Banc One Capital Markets, Inc., as Co-Syndication Agents,
and with Salomon Smith Barney Inc., as Lead Arranger and Sole Book Runner (the
"DTE Credit Agreement"), (ii) Section 3.01(h)(v) of the Credit Agreement, dated
as of November 7, 2001, among The Detroit Edison Company ("DECO"), the financial
institutions parties thereto (the "DECO Lenders") and Barclays Bank PLC, as
agent for said DECO Lenders, Salomon Smith Barney Inc. and Banc One Capital
Markets, Inc., as Co-Syndication Agents, and with Barclays Capital and Banc One
Capital Markets, Inc., as Co-Lead Arrangers and Joint Book Runners (the "DECO
Credit Agreement"), and (iii) Section 3.01(h)(v) of the Credit Agreement, dated
as of November 7, 2001, among Michigan Consolidated Gas Company ("MichCon"), the
financial institutions parties thereto (the "MichCon Lenders", and together with
the DTE Lenders and the DECO Lenders, the "Lenders") and Bank One, NA, as agent
for said Lenders, Barclays Bank PLC and Salomon Smith Barney Inc., as
Co-Syndication Agents, and with Banc One Capital Markets, Inc. and Barclays
Capital, as Co-Lead Arrangers and Joint Book Runners (the "MichCon Credit
Agreement", and together with the DTE Credit Agreement and the DECO Credit
Agreement, the "Credit Agreements"). Terms defined in each Credit Agreement are
used herein as therein defined.

                I am the Associate General Counsel of DTE, and the Vice
President and General Counsel of both DECO and MichCon, and have acted as
counsel for each of the Borrowers in connection with the preparation, execution
and delivery of the Loan Documents.

                In that connection, I, in conjunction with the members of my
staff, have examined:

                (1) Each Loan Document, executed by each of the parties thereto.

                (2) The other documents furnished by each of the Borrowers
        pursuant to Article III of each of the Credit Agreements.


                                       18
<PAGE>

                (3) The Restated Articles of Incorporation of DTE, the Restated
        Articles of Incorporation of DECO, and the Restated Articles of
        Incorporation of MichCon and all amendments thereto (the "Charters").

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

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

I have also examined the originals, or copies certified to my satisfaction, of
the documents listed in a certificate of a Financial Officer of each of the
Borrowers, dated the date hereof (the "Certificate"), certifying that the
documents listed in such certificate are all of the indentures, loan or credit
agreements, leases, guarantees, mortgages, security agreements, bonds, notes and
other agreements or instruments, and all of the orders, writs, judgments,
awards, injunctions and decrees, that affect or purport to affect each
Borrower's right to borrow money or each Borrower's obligations under the Loan
Documents to which it is party. 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 we 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 of the Borrowers
of the Loan Documents to which it is party, and the consummation of the
transactions contemplated thereby, are within each 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 each Borrower or (ii) any law,
rule or regulation applicable to each of the Borrowers (including, without
limitation, Regulation X of the Board of Governors of the Federal Reserve
System) or (iii) any contractual or legal restriction contained in any document
listed in the Certificate or, to the best of my knowledge (after due inquiry),
contained in any other similar document.

        3.      No authorization, 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 each is a party,
except such as have been obtained, including, in the case of DECO, the order of
the Federal Energy Regulatory Commission dated May 31, 2001.


                                       19
<PAGE>

        4.      Each Loan Document has been duly executed and delivered on
behalf of the Borrower thereto.

        5.      Except as may have been disclosed to you in the SEC Reports
designated in the Certificate, to the best of my knowledge (after due inquiry)
there are no pending or overtly threatened actions or proceedings affecting each
Borrower or any of its 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, binding effect or
enforceability of any Loan Documents or the consummation of the transactions
contemplated thereby.

        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.

        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.

        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 (including, without limitation, all laws
                relating to fraudulent transfers), reorganization, moratorium or
                similar law affecting creditors' rights generally.


                                       20
<PAGE>

                        (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.

                                            Very truly yours,
