               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

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

                                       12
<PAGE>

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) on
the Business Day of the proposed Borrowing in the case of a Borrowing consisting
of Base Rate Advances, by the Borrower to the Agent, which shall give to each
Lender prompt notice thereof by telecopier or telex. Each such notice of a
Borrowing (a "Notice of Borrowing") shall be by telephone, confirmed immediately
in writing, 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) at no time shall the sum
of (x) all Borrowings comprising Eurodollar Rate Advances outstanding hereunder
and (y) all "Borrowings" comprising "Eurodollar Rate Advances" outstanding
under, and as such terms are defined in, the Three-Year Agreement, be greater
than ten.

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

                                       13
<PAGE>

severally agree to repay to the Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount is
made available to the Borrower until the date such amount is repaid to the
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to Revolving Credit Advances comprising such Borrowing and (ii) in the case
of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent
such corresponding amount, such amount so repaid shall constitute such Lender's
Revolving Credit Advance as part of such Borrowing for purposes of this
Agreement.

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

         SECTION 2.03. Fees. (a) Facility Fee. The Borrower agrees to pay to the
Agent for the account of each Lender a facility fee (the "Facility Fee") on the
aggregate amount of such Lender's Commitment from the date hereof in the case of
each Initial Lender and from effective date specified in the Assignment and
Acceptance pursuant to which it became a Lender in the case of each other Lender
until all of the Revolving Credit Advances have been paid in full and the
Commitments under this Agreement have been terminated at a rate per annum equal
to the Applicable Percentage in effect from time to time, payable in arrears
quarterly on the last day of each March, June, September and December, and on
the Revolver Termination Date.

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

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

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

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

                                       14
<PAGE>

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

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

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

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

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

                                       15
<PAGE>

                  (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.

                  (a)      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.

                  (b)      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.

                  (c)      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.

                  (d)      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

                                       16
<PAGE>

being understood that such Conversion of a Revolving Credit Advance or of its
Interest Period does not constitute a repayment or prepayment of such Revolving
Credit Advance); provided, however, that any Conversion of Eurodollar Rate
Advances into Base Rate Advances shall be made only on the last day of an
Interest Period for such Eurodollar Rate Advances, any Conversion of Base Rate
Advances into Eurodollar Rate Advances shall be in an amount not less than the
minimum amount specified in Section 2.02(b) and no Conversion of any Revolving
Credit Advances shall result in more separate Borrowings than permitted under
Section 2.02(b). Each such notice of a Conversion shall, within the restrictions
specified above, specify (i) the date of such Conversion, (ii) the Revolving
Credit Advances to be Converted, and (iii) if such Conversion is into Eurodollar
Rate Advances, the duration of the initial Interest Period for each such
Eurodollar Rate Advance. Each notice of Conversion shall be irrevocable and
binding on the Borrower.

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

                  (b)      Mandatory Prepayment. The Borrower shall, upon five
Business Days notice from the Agent given at the request or with the consent of
the Required Lenders, prepay the aggregate principal amount outstanding plus all
interest thereon and all other amounts payable hereunder or under the Notes, in
the event that: (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

                                       17
<PAGE>

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 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.

                  (a)      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

                                       18
<PAGE>

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
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.

                  (a)      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.

                  (b)      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.

                  (c)      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
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").

                  (a)      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.

                  (b)      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.

                  (c)      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

                                       20
<PAGE>

Lender in the case of each other Lender, and from time to time thereafter as
requested in writing by the Borrower (but only so long as such Lender remains
lawfully able to do so), shall provide each of the Agent and the Borrower with
two original Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or
any successor or other form prescribed by the Internal Revenue Service,
certifying that such Lender is exempt from 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 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 W-8BEN or W-8ECI, that the Lender reasonably
considers to be confidential, the Lender shall give notice thereof to the
Borrower and shall not be obligated to include in such form or document such
confidential information.

                  (d)      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.

                  (e)      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

                                       21
<PAGE>

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

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

         SECTION 2.16. 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
$3,000 processing and recording fee in respect of such assignment shall be
payable by

                                       22
<PAGE>

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 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.

                           (i)      Each Lender shall maintain in accordance
                           with its usual practice an account or accounts
                           evidencing the indebtedness of the Borrower to such
                           Lender resulting from each 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.

                           (ii)     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.

                           (iii)    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.

                           (iv)     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

                                       23
<PAGE>

                           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

"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,

                  approvals, if any, with respect to each Loan Document to which
                  it is a party.

                  simultaneously with the initial Revolving Credit Advance
                  hereunder be terminated (except for those provisions that

applicable grace period, if any, specified in the agreement or instrument
relating to such Debt; or any other event shall occur or condition shall exist
under any agreement or instrument relating to any such Debt and shall continue

assignment for the benefit of creditors; or any proceeding shall

                                       32

judgment or order, by reason of a pending appeal or otherwise, shall not be in
effect; or

                  (h)      (i) any Person or "group" (within the meaning of

incur, or, in the reasonable opinion of the Required Lenders, shall be
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

                  (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;

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

                                       34
<PAGE>

willful misconduct. Without limitation of the generality of the foregoing, the
Agent: (i) may treat the payee in respect of any Revolving Credit Advance as the
owner thereof until the Agent receives and accepts an Assignment and Acceptance
entered into by the Lender that is the payee in respect of such Revolving Credit
Advance, as assignor, and an Eligible Assignee, as assignee, as provided in
Section 8.07; (ii) may consult with legal counsel (including counsel for the
Borrower), independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts; (iii)
makes no warranty or representation to any Lender and shall not be responsible
to any Lender for any statements, warranties or representations (whether written
or oral) made in or in connection with this Agreement; (iv) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants or conditions of this Agreement on the part of the Borrower
or to inspect the property (including the books and records) of the Borrower;
(v) shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to
be created under or in connection with, any Loan Document or any other
instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

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

         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

                                       35
<PAGE>

against the Agent in any way relating to or arising out of any Loan Document or
any action taken or omitted by the Agent under any Loan Document, provided that
no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Agent's gross negligence or willful misconduct.
Without limitation of the foregoing, each Lender agrees to reimburse the Agent
promptly upon demand for its ratable share of any out-of-pocket expenses
(including counsel fees) incurred by the Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, any Loan
Document, to the extent that the Agent is not reimbursed for such expenses by
the Borrower.

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

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

                                       36
<PAGE>

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,

and the Agent. All such notices and communications shall, when mailed,
telecopied, 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

                                       37
<PAGE>

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 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

                                       38
<PAGE>

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 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
and, for so long as no Default has occurred and is continuing, shall be made
concurrently with an assignment in a ratable amount of such Lender's rights and
obligations under the Three-Year Agreement (including, without limitation, all
or a portion of its "Commitment", "Revolving Credit Advances" owed to it and any
"Note" or "Notes" held by it under (and as each such term is defined in) the
Three-Year Agreement), (ii) except in the case of an assignment to a Person
that, immediately prior to such assignment, was a Lender or an assignment of all
of a Lender's rights and obligations under this Agreement, the amount of the
Commitment of the assigning Lender being assigned pursuant to each such
assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event be less than $10,000,000 or an
integral multiple of $1,000,000 in excess thereof, (iii) each such assignment
shall be to an Eligible Assignee, and (iv) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance, together with any Note subject to such
assignment and a processing and recordation fee of $3,000. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, (x) the assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, have the rights and
obligations of a Lender hereunder and (y) the Lender assignor thereunder shall,
to the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto).

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

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

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

                                       40
<PAGE>

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

                  (e)      Each Lender may sell participations to one or more
banks or other entities (other than the Borrower or any of its Affiliates) in or
to all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the
Revolving Credit Advances owing to it and any Note or Notes held by it);
provided, however, that (i) such Lender's obligations under this Agreement
(including, without limitation, its Commitment to the Borrower hereunder) shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) such Lender shall
remain the owner of such Revolving Credit Advances for all purposes of this
Agreement, (iv) the Borrower, the Agent and the other Lenders shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement and (v) no participant under any
such participation shall have any right to approve any amendment or waiver of
any provision of this Agreement or any Note, or any consent to any departure by
the Borrower therefrom, except to the extent that such amendment, waiver or
consent would (A) reduce the principal of, or interest on, the Revolving Credit
Advances or any fees or other amounts payable hereunder, or (B) increase the
Commitments, in each case to the extent subject to such participation, or
postpone any date fixed for any payment of principal of, or interest on, the
Revolving Credit Advances or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation. Each participant shall be
entitled to the benefits 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

                                       41
<PAGE>

"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

                                       42
<PAGE>

be incurred by or asserted against the Borrower, the Agent or such Lender, as
the case may be, in any way relating to or arising as a consequence of any such
forbearance or delay in the initiation of any such proceeding against its SPV.

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

         SECTION 8.08. Confidentiality. Neither the Agent nor any Lender shall
disclose any Confidential Information to any other Person without the consent of
the Borrower, other than (a) to the Agent's or such Lender's Affiliates and
their officers, directors, employees, agents and advisors and, as contemplated
by Section 8.07(f), to actual or prospective assignees and participants, and
then only on a confidential basis, (b) as required by any law, rule or
regulation or judicial process, (c) to any rating agency when required by it,
provided that, prior to any such disclosure, such rating agency shall undertake
to preserve the confidentiality of any Confidential Information relating to the
Borrower received by it from such Lender, (d) as requested or required by any
state, federal or foreign authority or examiner regulating banks or banking, and
(e) on a confidential basis to any Lender's direct or indirect contractual
counterparties in swap agreements or to legal counsel, accountants and other
professional advisors to such counterparties. Notwithstanding anything herein to
the contrary, Confidential Information shall not include, and each party hereto
(and each employee, representative or other agent of any party hereto) may
disclose to any and all persons, without limitation of any kind, the U.S.
federal income tax treatment and U.S. federal income tax structure of the
transactions contemplated hereby and all materials of any kind (including
opinions or other tax analyses) that are or have been provided to such party
relating to such tax treatment or tax structure, and it is hereby confirmed that
each party hereto has been authorized to make such disclosures since the
commencement of discussions regarding the transactions contemplated hereby.

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

         SECTION 8.10. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.
Delivery of an executed counterpart of a signature page to this Agreement by
telecopier shall be effective as delivery of a manually executed counterpart of
this Agreement.

SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties hereto hereby
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of any

                                       43
<PAGE>

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

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

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

                  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.

<PAGE>

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

                  "Status" means Level I Status, Level II Status, Level III
Status, Level IV Status 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.

the Credit Agreements 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 each of
the Credit Agreements and the Notes for periods prior to the Effective Date

         1.       The Effective Date shall be October 24, 2003.

         2.       The representation and warranties contained in Section 4.01 of
                  each of the Credit Agreements are true and current on and as

         3.       No event has occurred and is continuing that constitutes a
                  Default.

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

                  consummation of the transactions contemplated hereby and
                  thereby, are within each Borrower's corporate powers, have
                  been duly authorized by all necessary corporate action, and do
                  not contravene (i) each Borrower's charter or by-laws or (ii)
                  law or any contractual restriction binding on or affecting
                  each Borrower.

                  to the transactions contemplated by the Loan Documents to
                  which it is a party.

         7.       Each of the Loan Documents to which each of the Borrowers is a
                  party when delivered pursuant to each of the Credit Agreements
                  has been duly executed and delivered by each Borrower. Each of
                  the other Loan Documents to which each Borrower is a party
                  when delivered hereunder will be, the legal, valid and binding
                  obligation of each Borrower enforceable against each 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.

                  opinion of Deloitte & Touche LLP, independent public
                  accountants, and the condensed Consolidated balance sheets of
                  each of DTE, DECO, MichCon and their respective Subsidiaries

                  and said statements of income and cash flows for the six
                  months then ended, to year-end audit adjustments, the

                  of DTE, DECO, MichCon and their respective Subsidiaries, as

                  accordance with generally accepted accounting principles
                  consistently applied, and the respective reports in which such

                  there are no orders, writs, judgments, awards, injunctions or
                  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 a party.

         10.      Each of the Existing Credit Agreements is terminated (except
                  for those provisions that expressly survive the termination
                  thereof) upon effectiveness of the Credit Agreements on the
                  Effective Date; as of the date hereof, there are no loans
                  outstanding under any of the Existing Credit Agreements and

                                             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 each of the 364-Day and Three-Year Credit Agreements, dated as of
October 24, 2003, 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 Citigroup Global Markets Inc., as Lead
Arranger and Sole Book Runner (the "DTE Credit Agreements"), (ii) Section
3.01(h)(v) of each of the 364-Day and Three-Year Credit Agreements, dated as of
October 24, 2003, among The Detroit Edison Company ("DECO"), the financial
institutions parties thereto (the "DECO Lenders") and Barclays Bank PLC, as
agent for said DECO Lenders, Citigroup Global Markets 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 Agreements"), and (iii) Section 3.01(h)(v) of each of the 364-Day and
Three-Year Credit Agreements, dated as of October 24, 2003, 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 Citigroup Global Markets 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
Agreements and the DECO Credit Agreements, 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:

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

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

<PAGE>

                  (iii)    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").

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

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

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,

<PAGE>

                  including, in the case of DECO, the orders of the Federal
                  Energy Regulatory Commission and the Michigan Public Service
                  Commission.

         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.

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

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

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

qualifications:

                                    (i) 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.

                                    (ii) My opinion in paragraph 7 above as to
