                  SECTION 2.01.     The Revolving Credit Advances. Each Lender
severally agrees, on the terms and conditions hereinafter set forth, to make
Revolving Credit Advances to the Borrower from time to time on any Business Day
during the period from the Effective Date until the Revolver Termination Date in
an aggregate amount not to exceed at any time outstanding the amount set forth
opposite such Lender's name on Schedule 1 hereto or, if such Lender has entered
into any Assignment and Acceptance, set forth for such Lender in the Register
maintained by the Agent pursuant to Section 8.07(d), as such amount may be
reduced pursuant to Section 2.04 (such Lender's "Commitment"). Each Borrowing
shall be in an aggregate amount of $5,000,000 or an integral multiple of
$1,000,000 in excess thereof and shall consist of Revolving Credit Advances of
the same Type made on the same day by the Lenders ratably according to their
respective Commitments. Within the limits of each Lender's Commitment, the
Borrower may borrow under this Section 2.01, prepay pursuant to Section 2.09 and
reborrow under this Section 2.01.

                  SECTION 2.02.     Making the Revolving Credit Advances.

                  (a)      Each Borrowing shall be made on notice, given not
later than 11:00 A.M. (New York City 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 10:00 A.M. (New York City 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,
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 12:00 noon (New York City 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.

                                       13

<PAGE>

                  (c)      Each Notice of Borrowing shall be irrevocable and
binding on the Borrower. In the case of any Borrowing that the related Notice of
Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower
shall indemnify each Lender against any loss, cost or expense incurred by such
Lender as a result of any failure to fulfill on or before the date specified in
such Notice of Borrowing for such Borrowing the applicable conditions set forth
in Article III, including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund the
Revolving Credit Advance to be made by such Lender as part of such Borrowing
when such Revolving Credit Advance, as a result of such failure, is not made on
such date.

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

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

                  SECTION 2.03.     Fees.

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

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

                  (c)      Utilization Fee. If the aggregate outstanding amount

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.

                  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.

                           (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

remaining Reference Banks. The Agent shall give prompt notice to the Borrower

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.

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

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

<PAGE>

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

                  (f)      If fewer than two Reference Banks furnish timely
information to the Agent for determining the Eurodollar Rate for any Eurodollar
Rate Advances:

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

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

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

not later than 11:00 A.M. (New York City time) on the third Business Day prior
to the date of the proposed Conversion and subject to the provisions of Sections
2.07 and 2.11, Convert all Revolving Credit Advances of one Type comprising the
same Borrowing into Revolving Credit Advances of the other Type (it being
understood that such Conversion of a Revolving Credit Advance or of its Interest
Period does not constitute a repayment or prepayment of such Revolving Credit
Advance); provided, however, that any Conversion of Eurodollar Rate Advances
into Base Rate Advances shall be made only on the last day of an Interest Period
for such Eurodollar Rate Advances, any Conversion of Base Rate Advances into
Eurodollar Rate Advances shall be in an amount not less than the minimum amount
specified in Section 2.02(b) and no Conversion of any Revolving Credit Advances
shall result in more separate Borrowings than permitted under Section 2.02(b).
Each such notice of a Conversion shall, within the restrictions specified above,
specify (i) the date of such Conversion, (ii) the Revolving Credit Advances to
be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the
duration of the initial Interest Period for each such Eurodollar Rate Advance.
Each notice of Conversion shall be irrevocable and binding on the Borrower.

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

                                       17

ratably in part, together with accrued interest to the date of such prepayment
on the principal amount prepaid; provided, however, that (x) each partial
prepayment shall be in an aggregate principal amount of $5,000,000 or an
integral multiple of $1,000,000 in excess thereof and (y) in the event of any
such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to
reimburse the Lenders in respect thereof pursuant to Section 8.04(c).

                  (b)      Mandatory Prepayment. The Borrower shall, upon five
Business Days notice from the Agent given at the request or with the consent of
the Required Lenders, prepay the aggregate principal amount outstanding plus all
interest thereon and all other amounts payable hereunder or under the Notes, in
the event that: (i) any Person or two or more Persons acting in concert (other
than DTE Energy or any of its Subsidiaries) shall have acquired beneficial
ownership (within the meaning of Rule 13d-3 of the Securities and Exchange
Commission under the Securities Exchange Act of 1934), directly or indirectly,
of Voting Stock of the Borrower (or other securities convertible into such
Voting Stock) representing 20% or more of the combined voting power of all
Voting Stock of the Borrower; or (ii) any Person or two or more Persons acting
in concert (other than DTE Energy or any of its Subsidiaries) shall have
acquired by contract or otherwise, or shall have entered into a contract or
arrangement that, upon consummation, will result in its or their acquisition of
the power to exercise, directly or indirectly, a controlling influence over the
management or policies of the Borrower.

                  SECTION 2.10.     Increased Costs.

                  (a)      If, due to either (i) the introduction of or any
change in or in the interpretation of any law or regulation or (ii) the
compliance with any guideline or request from any central bank or other
governmental authority (whether or not having the force of law), there shall be
any increase in the cost to any Lender of agreeing to make or making, funding or
maintaining Eurodollar Rate Advances (excluding for purposes of this Section
2.10 any such increased costs resulting from (i) Taxes or Other Taxes (as to
which Section 2.13 shall govern) and (ii) changes in the basis of taxation of
overall net income or overall gross income by the United States or by the
foreign jurisdiction or state under the laws of which such Lender is organized
or has its Applicable Lending Office or any political subdivision thereof), then
the Borrower shall from time to time, upon demand by such Lender (with a copy of
such demand to the Agent), pay to the Agent for the account of such Lender
additional amounts sufficient to compensate such Lender for such increased cost.
A certificate as to the amount of such increased cost, submitted to the Borrower
and the Agent by such Lender, shall be conclusive and binding for all purposes,
absent manifest error.

                  (b)      If any Lender determines that compliance with any law
or regulation or any guideline or request from any central bank or other
governmental authority (whether or not 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

                                       18

<PAGE>

such Lender's commitment to lend hereunder. A certificate as to such amounts
submitted to the Borrower and the Agent by such Lender shall be conclusive and
binding for all purposes, absent manifest error.

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

                  SECTION 2.11.     Illegality. Notwithstanding any other
provision of this Agreement, if any Lender shall notify the Agent that the
introduction of or any change in or in the interpretation of any law or
regulation makes it unlawful, or any central bank or other governmental
authority asserts that it is unlawful, for any Lender or its Eurodollar Lending
Office to perform its obligations hereunder to make Eurodollar Rate Advances or
to fund or maintain Eurodollar Rate Advances hereunder, (i) each Eurodollar Rate
Advance will automatically, upon such demand, Convert into a Base Rate Advance
or a Revolving Credit Advance that bears interest at the rate set forth in
Section 2.06(a)(i), as the case may be, and (ii) the obligation of the Lenders
to make Eurodollar Rate Advances or to Convert Revolving Credit Advances into
Eurodollar Rate Advances shall be suspended until the Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no
longer exist.

                  SECTION 2.12.     Payments and Computations.

                  (a)      The Borrower shall make each payment hereunder and
under the Notes not later than 11:00 A.M. (New York City time) on the day when
due in U.S. dollars to the Agent at the Agent's Account in same day funds and
without set off, deduction or counterclaim. The Agent will promptly thereafter
cause to be distributed like funds relating to the payment of principal or
interest, facility fees or the Utilization Fee ratably (other than amounts
payable pursuant to Section 2.10, 2.13 or 8.04(c)) to the Lenders for the
account of their respective Applicable Lending Offices, and like funds relating
to the payment of any other amount payable to any Lender to such Lender for the
account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(c), from and after the effective date
specified in such Assignment and Acceptance, the Agent shall make all payments
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

                                       19

<PAGE>

charge from time to time against any or all of the Borrower's accounts with such
Lender any amount so due.

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

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

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

                  SECTION 2.13.     Taxes.

                  (a)      Any and all payments by the Borrower hereunder or
under the Notes shall be made, in accordance with Section 2.12, free and clear
of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender and the Agent, taxes imposed on
its overall net income, and franchise taxes imposed on it in lieu of net income
taxes, by the jurisdiction under the laws of which such Lender or the Agent (as
the case may be) is organized or any political subdivision thereof and, in the
case of each Lender, taxes imposed on its overall net income, and franchise
taxes imposed on it in lieu of net income taxes, by the jurisdiction of such
Lender's Applicable Lending Office or any political subdivision thereof (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and
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

                                       20

<PAGE>

case may be) receives an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law.

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

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

                  (d)      Within 30 days after the date of any payment of
Taxes, the Borrower shall furnish to the Agent, at its address referred to in
Section 8.02, the original or a certified copy of a receipt evidencing payment
thereof. In the case of any payment hereunder or under the Notes by or on behalf
of the Borrower through an account or branch outside the United States or by or
on behalf of the Borrower by a payor that is not a United States person, if the
Borrower determines that no Taxes are payable in respect thereof, the Borrower
shall furnish, or shall cause such payor to furnish, to the Agent, at such
address, an opinion of counsel acceptable to the Agent stating that such payment
is exempt from Taxes. For purposes of this subsection (d) and subsection (e),
the terms "United States" and "United States person" shall have the meanings
specified in Section 7701 of the Internal Revenue Code.

                  (e)      Each Lender organized under the laws of a
jurisdiction outside the United States, on or prior to the date of its execution
and delivery of this Agreement in the case of each Initial Lender and on the
date of the Assignment and Acceptance pursuant to which it becomes a Lender in
the case of each other Lender, and from time to time thereafter as requested in
writing by the Borrower (but only so long as such Lender remains lawfully able
to do so), shall provide each of the Agent and the Borrower with two original
Internal Revenue Service Form W-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

                                       21

<PAGE>

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.

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

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

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

                                       22

<PAGE>

                  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 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.

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

                  (b)      The Agent shall also maintain accounts in which it
will record (i) the date and the amount of each Revolving Credit Advance made
hereunder and the Interest Period, if any, applicable thereto, (ii) the amount
of any principal or interest due and payable or to become due and payable from
the Borrower to each Lender hereunder, (iii) the effective date and amount of
each Assignment and Acceptance delivered to and accepted by it and the parties
thereto pursuant to Section 8.07, (iv) the amount of any sum received by the
Agent hereunder from the Borrower and each Lender's share thereof, and (v) all
other appropriate debits and credits as provided in this Agreement, including,
without limitation, all fees, charges, expenses and interest.

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

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

                     CONDITIONS TO EFFECTIVENESS AND LENDING

during which a stay of enforcement of such judgment or order, by reason of a
pending appeal or otherwise, shall not be in effect; or

                  (g)      Any non-monetary judgment or order shall be rendered
against the Borrower or any of its Significant Subsidiaries that could be

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

                                  ARTICLE VII

                                   THE AGENT

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

                  SECTION 7.02.     Agent's Reliance, Etc. Neither the Agent nor
any of its directors, officers, agents or employees shall be liable for any
action taken or omitted to be taken by it or them under or in connection with
this Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the Agent:
(i) may treat the payee in respect of any Revolving Credit Advance as the owner
thereof until the Agent receives and accepts an Assignment and Acceptance
entered into by the Lender that is the payee in respect of such Revolving Credit
Advance, as assignor, and an Eligible Assignee, as assignee, as provided in
Section 8.07; (ii) may consult with legal counsel (including counsel for the
Borrower), independent public accountants and other experts selected by it and

                                       35
<PAGE>

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.     Barclays and Affiliates. With respect to its
Commitment, the Revolving Credit Advances made by it and any Note issued to it,
Barclays 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
Barclays in its individual capacity. Barclays 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
Barclays were not the Agent and without any duty to account therefor to the
Lenders.

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

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

                                       36
<PAGE>

(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 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

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.

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

legally permissible, and hold harmless the Agent and each Lender and each of
their Affiliates and their officers, directors, employees, agents and advisors
(each, an "Indemnified Party") from and against any and all claims, damages,
losses, liabilities and expenses (including, without limitation, reasonable fees
and expenses of counsel) that may be incurred by or asserted or awarded against
any Indemnified Party, in each case arising out of or in connection with or by
reason of, or in connection with the preparation for a defense of, any

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.

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

                                       39
<PAGE>

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,

                                       40

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 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 "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

                                       42
<PAGE>

any SPV to make any Revolving Credit Advance, (ii) if an SPV elects not to
exercise such option or otherwise fails to provide all or any part of such
Revolving Credit Advance, the Designating Lender shall be obligated to make such
Revolving Credit Advance pursuant to the terms hereof, (iii) the Designating
Lender shall remain liable for any indemnity or other payment obligation with
respect to its Commitment hereunder and (iv) no SPV or Designating Lender shall
be entitled to receive any greater amount under this Agreement than the
Designating Lender would have been entitled to receive had the Designating
Lender not otherwise granted such SPV the option to provide any Revolving Credit
Advance to the Borrower. The making of a Revolving Credit Advance by an SPV
hereunder shall utilize the Commitment of the Designating Lender to the same
extent, and as if, such Revolving Credit Advance were made by such Designating
Lender.

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

                  (j)      Each party hereto hereby agrees that no SPV shall be
liable for any indemnity or payment under this Agreement for which a Lender
would otherwise be liable so long as, and to the extent that, the related
Designating Lender provides such indemnity or makes such payment; provided, with
respect to such agreement by the Borrower that the related Designating Lender
shall not be in breach of its obligation to make Revolving Credit Advances to
the Borrower hereunder. In furtherance of the foregoing, each party hereto
hereby agrees (which agreements shall survive the termination of this Agreement)
that prior to the date that is one year and one day after the payment in full of
all outstanding commercial paper or other senior indebtedness of any SPV, it
will not institute against, or join any other person in instituting against,
such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any State thereof; provided,
with respect to such agreement by the Borrower that the related Designating
Lender shall not be in breach of its obligation to make Revolving Credit
Advances to the Borrower hereunder. Notwithstanding the foregoing, the
Designating Lender unconditionally agrees to indemnify the Borrower, the Agent
and each Lender against all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may be incurred by or asserted against the
Borrower, the Agent or such Lender, as the case may be, in any way relating to
or arising as a consequence of any such forbearance or delay in the initiation
of any such proceeding against its SPV.

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

                  SECTION 8.08.     Confidentiality. Neither the Agent nor any
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 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

                                       44
<PAGE>

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 issued by
Moody's and then in effect with respect to the Borrower's senior unsecured
long-term debt securities without third-party credit enhancement.

<PAGE>

                  "S&P Rating" means, at any time, the rating issued by S&P and
then in effect with respect to the Borrower's senior unsecured 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.

that it is an Eligible Assignee; (iv) appoints and authorizes the Agent to take

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

and construed in accordance with, the laws of the State of New York.

                  8.       This Assignment and Acceptance may be executed in any

                                                     [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 Agreements", 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.

<PAGE>

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

                           (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

<PAGE>

execution, delivery, recordation, filing or performance by each Borrower of the
Loan Documents to which each is a party, except such as have been obtained,
including, in the case of DECO, the 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);

<PAGE>

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

                           (a)      My opinion in paragraph 7 above as to
                  enforceability is subject to the effect of any applicable
                  bankruptcy, insolvency (including, without limitation, all
                  laws relating to fraudulent transfers), reorganization,
                  moratorium or similar law affecting creditors' rights
                  generally.

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

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

                                Very truly yours,
