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

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(a) and (ii) at no time shall the aggregate number of all

on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent

amount. If and to the extent that such Lender shall not have so made such ratable portion

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

the date of any Borrowing.

such a requested increase in the Commitments, any Lender or other financial institution which the
Borrower and the Agent invite to become a Lender or to increase its Commitment may set the amount
of its Commitment at a level agreed to by the Borrower and the Agent. In the event that the
Borrower and one or more of the Lenders (or other financial institutions) shall agree upon such an
increase in the Commitments (i) the Borrower, the Agent and each Lender or other financial
institution increasing its Commitment or extending a new Commitment shall enter into a supplement
to this Agreement (each, a “Lender Supplement”) substantially in the form of Exhibit
G setting forth, among other things, the amount of the increased Commitment of such Lender or
the new Commitment of such other financial institution, as applicable, and (ii) the Borrower shall
furnish, if requested, new or amended and restated Notes, as applicable, to each financial
institution that is extending a new Commitment and each Lender that is increasing its Commitment.
No such Lender Supplement shall require the approval or consent of any Lender whose Commitment is
not being increased. Upon the execution and delivery of such Lender Supplements as provided above
and the occurrence of the “Effective Date” specified therein, and upon satisfaction of such other
conditions as the Agent may reasonably specify, the financial institutions that are extending new
Commitments and the Lenders that are increasing their Commitments (including, without limitation,
the Agent administering the reallocation of the aggregate Revolving Credit Advances ratably among
the Lenders after giving effect to each such increase in the Commitments, and the delivery of
certificates, evidence of corporate authority and legal opinions on behalf of the Borrower), this
Agreement shall be deemed to be amended accordingly.

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

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

     (i) Base Rate Advances. During such periods as such Revolving Credit
Advance is a Base Rate Advance, a rate per annum equal at all times to the sum of
(x) the Base Rate in effect from time to time plus (y) the Applicable Margin
in effect from time to time, payable in arrears quarterly on the last day of

18

 

each March, June, September and December during such periods and on the date
such Base Rate Advance shall be Converted or paid in full.

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

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

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

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

          (c) If the Borrower shall fail to select the duration of any Interest Period for any
Eurodollar Rate Advances in accordance with the provisions contained in the definition of

19

 

“Interest Period” in Section 1.01, the Agent will forthwith so notify the Borrower and the
Lenders and such Eurodollar Rate Advances will automatically, on the last day of the then existing
Interest Period therefor, Convert into Base Rate Advances.

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

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

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

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

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

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

     SECTION 2.08. Optional Conversion of Revolving Credit Advances. The Borrower may on
any Business Day, upon notice given to the Agent not later than 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(a), 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

20

 

such Eurodollar Rate Advance. Each notice of Conversion shall be irrevocable and binding on
the Borrower.

     SECTION 2.09. Prepayments of Revolving Credit Advances. (a) Optional
Prepayment. The Borrower may on any Business Day, upon notice given to the Agent not later
than 11:00 A.M. (New York City time), (i) on the same day for Base Rate Advances and (ii) on the
second Business Day prior to the prepayment in the case of Eurodollar Rate Advances stating the
proposed date and aggregate principal amount of the prepayment (and if such notice is given the
Borrower shall) prepay the outstanding principal amount of the Revolving Credit Advances comprising
part of the same Borrowing in whole or ratably in part, together with accrued interest to the date
of such prepayment on the principal amount prepaid; provided, however, that (x)
each partial prepayment shall be in an aggregate principal amount of $5,000,000 or an integral
multiple of $1,000,000 in excess thereof, or the remaining balance, if less than $5,000,000, 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
outstanding principal amount of all Revolving Credit Advances plus all interest thereon and
all other amounts payable hereunder or under the Notes, in the event that any Person or two or more
Persons acting in concert (other than DTE Energy or any of its Subsidiaries) shall have acquired
beneficial ownership (within the meaning of Rule 13d-3 of the Securities and Exchange Commission
under the Securities Exchange Act of 1934), directly or indirectly, of Voting Stock of the Borrower
(or other securities convertible into such Voting Stock) representing 30% or more of the combined
voting power of all Voting Stock of the Borrower.

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

          (b) If any Lender determines that compliance with any law or regulation or any guideline or
request from any central bank or other Governmental Authority (whether or not having the force of
law) affects or would affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and that the amount of such capital is increased
by or based upon the existence of such Lender’s commitment to lend hereunder and other commitments
of this type, then, upon demand by such Lender (with a copy of such demand to the Agent), the
Borrower shall pay to the Agent for the account of such Lender, from time to time as specified by
such Lender, additional amounts sufficient to compensate such Lender or such corporation in the
light of such circumstances, to the extent that

21

 

such Lender reasonably determines such increase in capital to be allocable to the existence of
such Lender’s commitment to lend hereunder. A certificate as to such amounts submitted to the
Borrower and the Agent by such Lender shall be conclusive and binding for all purposes, absent
manifest error.

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

          (d) If any Lender requests compensation under this Section 2.10, then such Lender shall use
reasonable efforts to designate a different Applicable Lending Office for funding or booking its
Revolving Credit Advances hereunder or to assign its rights and obligations hereunder to another of
its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to this Section 2.10 in the
future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not
otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such designation or assignment.

     SECTION 2.11. Illegality.

          (a) 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.

          (b) If a Conversion occurs or the obligation of the Lenders to make Eurodollar Rate Advances
or to Convert Revolving Credit Advances into Eurodollar Rate Advances is suspended, in each case,
pursuant to Section 2.11(a), then the Lender causing such Conversion and/or suspension shall use
reasonable efforts to designate a different Applicable Lending Office for funding or booking its
Revolving Credit Advances hereunder or to assign its rights and obligations hereunder to another of
its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would reinstate the Lenders’ obligations to make

22

 

Eurodollar Rate Advances and to Convert Revolving Credit Advances into Eurodollar Rate
Advances and (ii) would not subject such Lender to any unreimbursed cost or expense and would not
otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such designation or assignment.

     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 other than deductions on account of taxes. The Agent will promptly thereafter
cause to be distributed like funds relating to the payment of principal or interest or Facility
Fees ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 8.04(c)) to the Lenders
for the account of their respective Applicable Lending Offices, and like funds relating to the
payment of any other amount payable to any Lender to such Lender for the account of its Applicable
Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon
its acceptance of an Assignment and Acceptance and recording of the information contained therein
in the Register pursuant to Section 8.07(c), from and after the effective date specified in such
Assignment and Acceptance, the Agent shall make all payments hereunder and under the Notes in
respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such
Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior
to such effective date directly between themselves.

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

          (c) All computations of interest based on the Base Rate, when such computations of the Base
Rate are based on the Prime 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 Base Rate (other than such
computations of the Base Rate that are based on the Prime Rate), of interest based on the
Eurodollar Rate, and of the Facility Fees 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 or Facility Fees 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 or
Facility 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.

23

 

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

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

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

24

 

          (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 United States withholding tax on payments pursuant to this
Agreement or the Notes. If any form or document referred to in this subsection (e) requires the
disclosure of information, other than information necessary to compute the tax payable and
information required on the date hereof by Internal Revenue Service Form W-8BEN or W-8ECI, that the
Lender reasonably considers to be confidential, the Lender shall give notice thereof to the
Borrower and shall not be obligated to include in such form or document such confidential
information; however, such a Lender will not be entitled to any payment or indemnification
on account of any Taxes imposed by the United States.

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

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

          (h) In the event that a Lender demands payment from the Borrower for amounts owing pursuant to
subsection (a) or (b) of this Section 2.13, the Borrower may, upon payment of such amounts and
subject to the requirements of Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial institution shall be an Eligible

25

 

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.

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

          (j) If the Borrower is required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to this Section 2.13, then such Lender shall use
reasonable efforts to designate a different Applicable Lending Office for funding or booking its
Revolving Credit Advances hereunder or to assign its rights and obligations hereunder to another of
its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to this Section 2.13 in the
future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not
otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such designation or assignment.

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

     SECTION 2.15. Use of Proceeds. The proceeds of the Revolving Credit Advances shall be
available (and the Borrower agrees that it shall use such proceeds) solely for refinancing

26

 

Debt of the Borrower under the Existing Credit Agreement (if any), and for general corporate
purposes, including commercial paper liquidity, of the Borrower and its Subsidiaries.

     SECTION 2.16. 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.

     SECTION 2.17. Defaulting Lenders. Notwithstanding any provision of this Agreement to
the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply
for so long as such Lender is a Defaulting Lender:

     (a) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting
Lender pursuant to Section 2.03(a);

     (b) the Commitment and Revolving Credit Advances of such Defaulting Lender shall not be
included in determining whether the Required Lenders have taken or may take any action hereunder
(including any consent to any amendment or waiver pursuant to Section 8.01, other than those which
require the consent of all Lenders or of each affected Lender);

27

 

     (c) the Borrower may, subject to the requirements of Sections 8.04 and 8.07, substitute for
such Defaulting Lender another financial institution, which financial institution shall be an
Eligible Assignee and shall assume the Commitments of such Defaulting Lender and purchase the
Revolving Credit Advances held by such Defaulting 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 Defaulting 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;

     (d) to the extent the Agent receives any payments or other amounts for the account of a
Defaulting Lender, such Defaulting Lender shall be deemed to have requested that the Agent use such
payment or other amount to fulfill such Defaulting Lender’s previously unsatisfied obligations to
fund a Revolving Credit Advance or any other unfunded payment obligation of such Defaulting Lender
under Section 2.02(d), 2.12(e) or 7.05;

     (e) no Lender shall be deemed to have consented to increase its Commitment pursuant to Section
2.04(c) unless that Lender shall have affirmatively given consent in accordance with that Section;
and

     (f) for the avoidance of doubt, the Borrower shall retain and reserve its other rights and
remedies respecting each Defaulting Lender.

In the event that the Agent and the Borrower each agrees that a Defaulting Lender has adequately
remedied all matters that caused such Lender to be a Defaulting Lender, such Lender shall purchase
at par on a ratable basis such of the Revolving Credit Advances of the other Lenders as the Agent
shall determine may be necessary in order for such Lender to hold such Revolving Credit Advances in
accordance with its Pro Rata Share.

ARTICLE VII:

THE AGENT

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

     SECTION 7.02. Agent’s Reliance, Etc. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable for any action taken or omitted to be taken by it or
them under or in connection with this Agreement, except for its or their own gross negligence or
willful misconduct. Without limitation of the generality of the foregoing, the Agent: (i) may
treat the payee in respect of any Revolving Credit Advance as the owner thereof until the Agent
receives and accepts an Assignment and Acceptance entered into by the Lender that is the payee in
respect of such Revolving Credit Advance, as assignor, and an Eligible Assignee, as assignee, as
provided in Section 8.07; (ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts; (iii) makes no warranty or representation to any Lender and shall
not be responsible to any Lender for any statements, warranties or representations (whether

39

 

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. JPMCB and Affiliates. With respect to its Commitment, the Revolving
Credit Advances made by it and any Note issued to it, JPMCB 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 JPMCB in
its individual capacity. JPMCB 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 JPMCB 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), solely in its capacity as Agent hereunder, ratably
according to the respective principal amounts of their respective Revolving Credit Advances (or if
no Revolving Credit Advances are at the time outstanding or if any Revolving Credit Advances are
owing to Persons that are not Lenders, ratably according to the respective amounts of their
Commitments), from and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that
may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out
of any Loan Document or any action taken or omitted by the Agent under any Loan Document,
provided that no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each
Lender agrees to reimburse the Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including reasonable counsel fees) incurred by the Agent, solely in its
capacity as Agent hereunder, in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through negotiations, legal

40

 

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 $500,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed
to and become vested with all the rights, powers, discretion, privileges and duties of the retiring
Agent, and the retiring Agent shall be discharged from its duties and obligations under this
Agreement. After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of
this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent under this Agreement.

     SECTION 7.07. Co-Syndication Agents and Documentation Agent. None of the Lenders
identified in this Agreement as a Co-Syndication Agent or a Documentation Agent shall have any
right, power, obligation, liability, responsibility or duty under this Agreement other than those
applicable to all Lenders as such. Without limiting the foregoing, none of such Lenders shall have
or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same
acknowledgments with respect to such Lenders as it makes with respect to the Agent in Section 7.04.

ARTICLE VIII:

mail address as the Agent shall identify to the Borrower. In addition, the Borrower shall continue
to provide the Communications to the Agent in the manner specified in this Agreement but only to
the extent requested by the Agent. The Borrower further agrees that the Agent may make the
Communications available to the Lenders by posting the Communications on Intralinks, or a
substantially similar electronic transmission system mutually agreeable to the Agent and the

the Agent or any Lender to give any notice or other communication pursuant hereto or to any other
Loan Document in any other manner specified herein or therein.

42

 

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

to ensure that the Agent has on record an effective e-mail address for the Borrower to which the
foregoing notices may be sent by electronic transmission and (B) that the foregoing notices may be
sent to such e-mail address. Each Lender agrees that e-mail notice to it (at the address provided
pursuant to the next sentence and deemed delivered as provided in subclause (iii) below) specifying
that the Communications have been posted to the Platform shall constitute effective delivery of the
Communications to such Lender for purposes of the Loan Documents. Each Lender agrees (A) to notify
the Agent in writing (including by electronic communication) from time to time of such Lender’s
e-mail address to which the foregoing notice may be sent by electronic transmission and (B) that

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

               (iv) The parties hereto acknowledge and agree that the distribution of the Communications and
other material through an electronic medium is not necessarily secure and that there are
confidentiality and other risks associated with such distribution. EACH OF THE PARTIES HERETO
ACKNOWLEDGES AND AGREES AS FOLLOWS: (A) THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”;
(B) THE AGENT PARTIES DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE
ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE
COMMUNICATIONS; (C) NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT
LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF
THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN
CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM; AND (D) IN NO EVENT SHALL THE AGENT OR ANY OF
ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR

43

 

DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER

FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

               (v) This clause (b) shall terminate on the date that neither JPMCB nor any of its Affiliates
is the Agent under this Agreement.

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

     SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to pay on demand, upon
presentation of a statement of account and absent manifest error, all reasonable costs and
reasonable expenses of the Agent in connection with the preparation, execution, delivery,

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

          (b) The Borrower agrees to indemnify, to the extent legally permissible, and hold harmless the
Agent and each Lender and each of their Affiliates and their officers, directors, employees, agents
and advisors (each, an “Indemnified Party”) from and against any and all claims, damages,
losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of
counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of, or in connection with the preparation for a
defense of, any investigation, litigation or proceeding arising out of, related to or in connection
with (i) the Loan Documents, any of the transactions contemplated herein or therein or the actual
or proposed use of the proceeds of the Revolving Credit Advances or (ii) the actual or alleged
presence of Hazardous Materials on any property of the Borrower or any of its Subsidiaries or any
Environmental Action relating in any way to the Borrower or any of its Subsidiaries, in each case

44

 

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; provided
that upon receipt of notice of any such matter by a representative of the Agent or any Lender, as
applicable, having primary responsibility for the relationship between the Borrower and the Agent
or such Lender, as applicable, the Agent or such Lender, as applicable, shall promptly notify the
Borrower to the extent permitted by applicable law. The Borrower shall have no liability for any
settlement effected without its prior written consent, which consent shall not be unreasonably
withheld or delayed. The Borrower also agrees not to assert any claim against the Agent, any
Lender, any of their Affiliates, or any of their respective directors, officers, employees,
attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive
damages arising out of or otherwise relating to the Loan Documents, any of the transactions
contemplated herein or therein or the actual or proposed use of the proceeds of the Revolving
Credit Advances.

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

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

     SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the continuance of
any Event of Default and (ii) the making of the request or the granting of the consent specified by

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 Agent and 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.

45

 

The rights of each Lender and its Affiliates under this Section are in addition to other
rights and remedies (including, without limitation, other rights of set-off) that such Lender and
its Affiliates may have.

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

     SECTION 8.07. Assignments, Designations and Participations. (a) Each Lender may (i)
with the prior consent of the Agent (which consent shall not be unreasonably withheld, and which
consent shall not be required in the event of an assignment or grant pursuant to Sections 8.07(g)
or (h) or an assignment to any other Lender, an Affiliate of a Lender, or an Approved Fund) and
(ii) for so long as no Default has occurred and is continuing, with the consent of the Borrower
(which consent shall not be unreasonably withheld, and which consent shall not be required in the
event of an assignment or grant pursuant to Sections 8.07(g) or (h) or an assignment to any other
Lender, an Affiliate of a Lender, or an Approved Fund), 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 (A) each such assignment shall be of a constant, and
not a varying, percentage of all rights and obligations under this Agreement, (B) 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, (C) each such
assignment shall be to an Eligible Assignee, and (D) 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, (1) 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 (2) 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,

46

 

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.

47

 

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

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

          (g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any
time 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 Person (other than the Borrower or an Affiliate of the Borrower), including, without
limitation, any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of
the Federal Reserve System.

          (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

48

 

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.

49

 

          (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 the Agent or such Lender,
(d) as requested or required by any state, federal or foreign authority or examiner regulating
banks, other financial institutions or banking, (e) in connection with the exercise of any remedies
hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights
hereunder, (f) on a confidential basis to any Lender’s direct or indirect contractual
counterparties in swap agreements or to legal counsel, accountants and other professional advisors
to such counterparties, and (g) subject to an agreement containing provisions substantially the
same as those of this Section, (x) to any credit or financial insurance provider in connection with
the Borrower’s obligations hereunder, and (y) to any Person that requires such Confidential
Information in connection with obtaining CUSIP-based identifiers.

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

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

     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

50

 

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

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

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

     SECTION 8.13. USA Patriot Act Notification. The following notification is provided to
the Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government
fight the funding of terrorism and money laundering activities, Federal law requires all financial
institutions to obtain, verify, and record information that identifies each person or entity that
opens an account, including any deposit account, treasury management account, loan, other extension
of credit, or other financial services product. What this means for the Borrower: When the
Borrower opens an account, the Agent and the Lenders will ask for the Borrower’s name, tax
identification number, business address, and other information that will allow the Agent and the
Lenders to identify the Borrower. The Agent and the Lenders may also ask to see the Borrower’s
legal organizational documents or other identifying documents.

     SECTION 8.14. Severability. In the event any one or more of the provisions contained
in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein shall not in any way be
affected or impaired thereby.

          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 Status or Level IV Status.

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

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

          “Status” means Level I Status, Level II Status, Level III Status, Level IV Status or Level V
Status.

 

 

          The Applicable Margin and Applicable Percentage shall be determined in accordance with the
foregoing table based on the Borrower’s Status as determined from its then-current Moody’s and S&P
Ratings. The credit rating in effect on any date for the purposes of
this Schedule is that in effect at the close of business on such date. If at any time the
Borrower does not have both a Moody’s Rating and an S&P Rating, Level V Status shall exist;
provided, however, that if the credit rating system of Moody’s or S&P shall change,
or if either such rating agency shall cease to be in the business of rating corporate debt
obligations, the Borrower and the Lenders shall negotiate in good faith to amend this Schedule to
reflect such changed rating system or the unavailability of ratings from such rating agency and,
pending the effectiveness of any such amendment, the applicable Status for the Borrower shall be
the Borrower’s Status most recently in effect prior to such change or cessation.

          Except as specifically provided above in this Schedule, in the event that a split occurs
between the two ratings, the pricing shall be based upon (x) the higher of the two ratings then
applicable if all such ratings shall be in Level I Status, Level II Status, Level III Status or
Level IV Status and (y) the lower of the two ratings if any of such ratings shall be in Level V
Status. However, if (x) the split is greater than one level and the lowest rating shall be in
Level III Status or Level IV Status, then the pricing shall be based upon the rating one level
above the lower of the two ratings and (y) the split is greater than one level and the lowest
rating shall be in Level V Status, then pricing shall be based upon Level V Status.

set forth on Schedule 1 hereto.

          2. The Assignor (i) represents and warrants that it is the legal and beneficial owner of the
interest being assigned by it hereunder and that such interest is free and clear of any adverse
claim; (ii) makes no representation or warranty and assumes no responsibility with respect to any

Commitment assumed by the Assignee pursuant hereto and the Credit Agreement or new Notes payable to
the order of the Assignee in an amount equal to the Commitment assumed by the Assignee pursuant
hereto and the Credit Agreement and the Assignor in an amount equal to the Commitment retained by
the Assignor under the Credit Agreement, respectively, as specified on Schedule 1 hereto.

          3. The Assignee (i) confirms that it has received a copy of the Credit Agreement, together
with copies of the financial statements referred to in Section 4.01 thereof and such other
documents and information as it has deemed appropriate to make its own credit analysis and decision
to enter into this Assignment and Acceptance; (ii) agrees that it will, independently and without

information as it shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Credit Agreement; (iii) confirms that it is an Eligible
Assignee; (iv) appoints and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers and discretion under the Credit Agreement as are delegated to the Agent by the

Acceptance, have the rights and obligations of a Lender thereunder and (ii) the Assignor shall, to
the extent provided in this Assignment and Acceptance, relinquish its rights and be released from
its obligations under the Credit Agreement.

Agent shall make all payments under the Credit Agreement, and the Notes in respect of the interest
assigned hereby (including, without limitation, all payments of principal, interest and Facility
Fees with respect thereto) to the Assignee. The Assignor and Assignee shall make all appropriate
adjustments in payments under the Credit Agreement, and the Notes for periods prior to the
Effective Date directly between themselves.

          7. This Assignment and Acceptance shall be governed by, and construed in accordance with, the
laws of the State of New York.

          8. This Assignment and Acceptance 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.

EXHIBIT
E-1 - FORM OF

OPINION OF GENERAL COUNSEL TO THE BORROWER

April 29, 2009

To each of the Lenders party to the

Credit Agreement defined below

Michigan Consolidated Gas Company

Ladies and Gentlemen:

          This opinion is furnished to you pursuant to Section 3.01(g)(v) of the Two-Year Credit
Agreement (the “Credit Agreement”), dated as of April 29, 2009, among Michigan Consolidated
Gas Company (the “Borrower”), the financial institutions from time to time parties thereto
as “Lenders” and JPMorgan Chase Bank, N.A. (the “Agent”), as agent for said Lenders. Terms
defined in the Credit Agreement are used herein as therein defined.

          I am the General Counsel of the Borrower, and have acted as counsel for the Borrower in
connection with the preparation, execution and delivery of the Loan Documents.

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

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

     (ii) The other documents furnished by the Borrower pursuant to Article III of the
Credit Agreement.

     (iii) The Restated Articles of Incorporation of the Borrower and all amendments thereto
(the “Charter”).

     (iv) The Bylaws of the Borrower and all amendments thereto (the “Bylaws”).

     (v) A certificate from the State of Michigan attesting to the continued corporate
existence and good standing of the Borrower.

In addition, I have examined the originals or copies certified to my satisfaction, of such other
corporate records of the Borrower, certificates of public officials and of officers of the
Borrower, and agreements, instruments and other documents, as I have deemed necessary as a basis
for the opinions expressed below. As to questions of fact material to such opinions, I have, when
relevant facts were not independently established by me, relied upon certificates of public
officials. I have assumed the due execution and delivery, pursuant to due authorization, of the
Credit Agreement by the Lenders and the 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. The Borrower 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 the Borrower of the Loan Documents to which it
is party, and the consummation of the transactions contemplated thereby, are within the Borrower’s
corporate powers, have been duly authorized by all necessary corporate action, and do not
contravene (i) the Charter or the Bylaws, (ii) any law, rule or regulation applicable to the
Borrower, or (iii) any contractual restriction binding on or affecting the Borrower.

          3. No consent, authorization or approval or other action by, and no notice to or filing with,
any Governmental Authority or regulatory body or any other third party is required for the due
execution, delivery, recordation, filing or performance by the Borrower of the Loan Documents to
which it is a party.

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

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

          6. In a properly presented case, a Michigan court or a federal court sitting in the State of
Michigan applying Michigan choice of law rules should give effect to the choice of law provisions
of the Loan Documents and should hold that the 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 the Credit Agreement, 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 Loan Documents would be, under the laws of
the State of Michigan, legal, valid and binding obligations of the Borrower, enforceable against
the Borrower in accordance with their respective terms.

          8. Neither the Borrower nor any of its 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;

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

 

 

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

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

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

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

OPINION OF HUNTON & WILLIAMS LLP

April 29, 2009

To each of the Lenders party to the

Credit Agreements defined below

DTE Energy Company

The Detroit Edison Company

Michigan Consolidated Gas Company

Ladies and Gentlemen:

          This opinion is delivered to you pursuant to Section 3.01(g)(v) of each of (i) the Two-Year
Credit Agreement (the “DTE Credit Agreement”), dated as of April 29, 2009, among DTE Energy
Company (“DTE”), the financial institutions from time to time parties thereto as “Lenders”
and Citibank, N.A. (“Citibank”), as agent for said Lenders, (ii) the Two-Year Credit
Agreement (the “DECO Credit Agreement”), dated as of April 29, 2009, among The Detroit
Edison Company (“DECO”), the financial institutions from time to time parties thereto as
“Lenders” and Barclays Bank PLC (“Barclays”), as agent for said Lenders, and (iii) the
Two-Year Credit Agreement (the “MichCon Credit Agreement”, and, together with the DTE
Credit Agreement and the DECO Credit Agreement, the “Credit Agreements”), dated as of April
29, 2009, among Michigan Consolidated Gas Company (“MichCon”), the financial institutions
from time to time parties thereto as “Lenders” and JPMorgan Chase Bank, N.A. (“JPMCB”), as
agent for said Lenders. Terms used herein which are defined in each Credit Agreement shall have
the respective meanings set forth in each Credit Agreement, unless otherwise defined herein.

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

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

 

 

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

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

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

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

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

          We express no opinion with respect to: (a) the effect of any provision of the Loan Documents
that is intended (i) to establish any standard as the measure of the performance by any party
thereto of such party’s obligations of good faith, diligence, fair dealing, reasonableness or care
or (ii) to permit modification thereof only by means of an agreement in writing signed by the
parties thereto; (b) the effect of any provision of the Loan Documents insofar as it provides that
any Person purchasing a participation from a Lender or other Person may exercise set-off or similar
rights with respect to such participation or that any Lender or other Person may exercise set-off
or similar rights other than in accordance with applicable law; (c) the effect of any provision of
the Loan Documents imposing penalties or forfeitures; (d) the effect of any provision of the Loan
Documents relating to indemnification or exculpation in connection with

 

 

violations of any securities laws or relating to indemnification, contribution or exculpation
in connection with willful, reckless or criminal acts or gross negligence of the indemnified or
exculpated Person or the Person receiving contribution; (e) any provision of the Loan Documents
which purports to provide for a waiver by the Borrowers of any immunity, defense or right which may
be available to the Borrowers; and (f) any provision of the Loan Documents which purports to
establish an evidentiary standard for determinations by any Person.

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

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

          This opinion letter is rendered to you in connection with the above-described transactions.
This opinion letter may not be relied upon by you for any other purpose, or relied upon by any
other person or entity without our prior written consent (provided, that this opinion Letter may be
furnished to and relied upon by a subsequent assignee of, or participant under, the Credit
Agreements and a Note, if any, solely for the purpose of such assignment or participation, subject
to the assumptions, limitations and qualifications set forth herein without our prior written
consent). This opinion letter speaks only as of its date, there is no assurance that it will be
correct as of any date after its date, and we undertake no duty to inform you or any assignee or
participant of events occurring subsequent to the date hereof.

Very truly yours,

ARTICLE II

AMOUNTS AND TERMS OF THE REVOLVING CREDIT ADVANCES

          SECTION 2.01. Commitment. 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 Termination Date in an aggregate
amount not to exceed at any time outstanding 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, or the
remaining balance of Commitments available for a Borrowing, if such balance is less than
$5,000,000, 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 signed by a Financial Officer in substantially the
form of Exhibit B hereto, specifying therein the requested (i) date of such Borrowing, (ii) Type
of Revolving Credit Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing,
(iv) in the case of a Borrowing consisting of Eurodollar Rate Advances, initial Interest Period
for each such Revolving Credit Advance and (v) wire transfer instructions. Each Lender shall,
before 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 as specified in the Notice of Borrowing.

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

          (c) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case
of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar
Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred
by such Lender as a result of any failure to fulfill on or before the date

16

 

specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth
in Article III, including, without limitation, any loss (excluding loss of anticipated profits),
cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds
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 time 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 Obligations 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 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.

          SECTION 2.04. Termination or Reduction of the Commitments; Increase of the
Commitments.

          (a) The Commitments shall be automatically terminated on the Termination Date.

17

 

          (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, or the remaining
balance, if less than $5,000,000. Once terminated, a Commitment or portion thereof may not be
reinstated.

          (c) At any time prior to the Termination Date the Borrower may, on the terms set forth below,
request that the Commitments hereunder be increased; provided, however, that (i)
an increase in the Commitments hereunder may only be made at a time when no Default shall have
occurred and be continuing, (ii) the “Commitments” under each of the DTE Credit Agreement and the
MichCon Credit Agreement (as such term is defined in each of the respective Credit Agreements)
must be simultaneously increased by a ratable portion (in proportion to the aggregate
“Commitments” under each such Credit Agreement (as such term is defined in each of the respective
Credit Agreements)) pursuant to and in accordance with Section 2.04(c) of each thereof, and (iii)
in no event shall the aggregate “Commitments” under all Credit Agreements (as such term is defined
in each of the respective Credit Agreements) (x) exceed $1,025,000,000, or (y) be increased
pursuant to Section 2.04(c) of each Credit Agreement by an aggregate amount in excess of
$25,000,000. In the event of such a requested increase in the Commitments, any Lender or other
financial institution which the Borrower and the Agent invite to become a Lender or to increase
its Commitment may set the amount of its Commitment at a level agreed to by the Borrower and the
Agent. In the event that the Borrower and one or more of the Lenders (or other financial
institutions) shall agree upon such an increase in the Commitments (i) the Borrower, the Agent and
each Lender or other financial institution increasing its Commitment or extending a new Commitment
shall enter into a supplement to this Agreement (each, a “Lender Supplement”)
substantially in the form of Exhibit G setting forth, among other things, the amount of
the increased Commitment of such Lender or the new Commitment of such other financial institution,
as applicable, and (ii) the Borrower shall furnish, if requested, new or amended and restated
Notes, as applicable, to each financial institution that is extending a new Commitment and each
Lender that is increasing its Commitment. No such Lender Supplement shall require the approval or
consent of any Lender whose Commitment is not being increased. Upon the execution and delivery of
such Lender Supplements as provided above and the occurrence of the “Effective Date” specified
therein, and upon satisfaction of such other conditions as the Agent may reasonably specify, the
financial institutions that are extending new Commitments and the Lenders that are increasing
their Commitments (including, without limitation, the Agent administering the reallocation of the
aggregate Revolving Credit Advances ratably among the Lenders after giving effect to each such
increase in the Commitments, and the delivery of certificates, evidence of corporate authority and
legal opinions on behalf of the Borrower), this Agreement shall be deemed to be amended
accordingly.

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

plus (y) the Applicable Margin in effect from time to time, payable in
arrears on the last day of such Interest Period and, if such Interest Period has a
duration of more than three months, on each day that occurs during such Interest

the purpose of determining each Eurodollar Rate. If any one or more of the Reference Banks shall
not furnish such timely information to the Agent for the purpose of determining any such interest

that the Eurodollar Rate for any Interest Period for such Eurodollar Rate Advances will not
adequately reflect the cost to such Required Lenders of making, funding or maintaining their
respective Eurodollar Rate Advances for such Interest Period, the Agent shall forthwith so notify

Eurodollar Rate Advances in accordance with the provisions contained in the definition of

therefor, Convert into a Base Rate Advance (or if such Advance is then a Base Rate
Advance, will continue as a Base Rate Advance), and

     (iii) the obligation of the Lenders to make Eurodollar Rate Advances or to
Convert Revolving Credit Advances into Eurodollar Rate Advances shall be suspended
until the Agent shall notify the Borrower and the Lenders that the circumstances

in more separate Borrowings than permitted under Section 2.02(b). Each such notice of a Conversion

Revolving Credit Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate

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

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

21

 

increased costs resulting from taxes (as to which Section 2.13 shall govern), then the
Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the
Agent), pay to the Agent for the account of such Lender additional amounts sufficient to
compensate such Lender for such increased cost. A certificate as to the amount of such increased
cost, submitted to the Borrower and the Agent by such Lender, shall be conclusive and binding for
all purposes, absent manifest error.

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

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

          (d) If any Lender requests compensation under this Section 2.10, then such Lender shall use
reasonable efforts to designate a different Applicable Lending Office for funding or booking its
Revolving Credit Advances hereunder or to assign its rights and obligations hereunder to another
of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to this Section 2.10 in the
future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not
otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such designation or assignment.

          SECTION 2.11. Illegality.

          (a) 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

22

 

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.

          (b) If a Conversion occurs or the obligation of the Lenders to make Eurodollar Rate Advances
or to Convert Revolving Credit Advances into Eurodollar Rate Advances is suspended, in each case,
pursuant to Section 2.11(a), then the Lender causing such Conversion and/or suspension shall use
reasonable efforts to designate a different Applicable Lending Office for funding or booking its
Revolving Credit Advances hereunder or to assign its rights and obligations hereunder to another
of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would reinstate the Lenders’ obligations to make Eurodollar Rate Advances and to
Convert Revolving Credit Advances into Eurodollar Rate Advances and (ii) would not subject such
Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such
Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any
Lender in connection with any such designation or assignment.

          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 other than deductions on account
of taxes. The Agent will promptly thereafter cause to be distributed like funds relating to the
payment of principal or interest or Facility Fees ratably (other than amounts payable pursuant to
Section 2.10, 2.13 or 8.04(c)) to the Lenders for the account of their respective Applicable
Lending Offices, and like funds relating to the payment of any other amount payable to any Lender
to such Lender for the account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance
and recording of the information contained therein in the Register pursuant to Section 8.07(c),
from and after the effective date specified in such Assignment and Acceptance, the Agent shall
make all payments hereunder and under the Notes in respect of the interest assigned thereby to the
Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all
appropriate adjustments in such payments for periods prior to such effective date directly between
themselves.

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

          (c) All computations of interest based on the Base Rate, when such computations of the Base
Rate are based on the Prime Rate, shall be made by the Agent on the

23

 

basis of a year of 365 or 366 days, as the case may be, and all computations of interest
based on the Base Rate (other than such computations of the Base Rate that are based on the Prime
Rate), of interest based on the Eurodollar Rate, and of the Facility Fees 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 or
Facility Fees 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 or
Facility 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) Subject to the exclusions set forth below in this Section 2.13(a) and, if applicable,
compliance with Section 2.13(e), any and all payments by the Borrower hereunder or under the Notes
shall be made, in accordance with Section 2.12, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Lender and the Agent, any
and all present or future taxes, levies, imposts, deductions, charges or withholdings imposed on
its income, and franchise taxes imposed on it in lieu of income taxes, (i) by the jurisdiction
under the laws of which such Lender or the Agent (as the case may be) is organized or any
political subdivision thereof and (ii), in the case of each Lender, by the jurisdiction of such
Lender’s Applicable Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments
hereunder or under the Notes being hereinafter referred to as “Taxes”). Notwithstanding
the above, if the Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note to any Lender or the Agent, the Borrower will so deduct
and (i) the sum payable shall be increased as may be necessary so that after making all such
deductions on account of Taxes (including deductions on account of Taxes applicable to additional
sums payable under this Section 2.13) such Lender or the Agent (as the case may be) receives an
amount equal to the sum it would have received had no such

24

 

deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower
shall pay the full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

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

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

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

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

          (f) Notwithstanding any provision to the contrary in this Agreement, the Borrower will not be
obligated to make payments on account of or indemnify the Lenders or the

25

 

Agents for any present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, or any present or future stamp or other documentary
taxes or property taxes, charges or similar levies that are neither Taxes nor Other Taxes.

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

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

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

          (j) If the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to this Section 2.13, then such
Lender shall use reasonable efforts to designate a different Applicable Lending Office for funding
or booking its Revolving Credit Advances hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender,
such designation or assignment (i) would eliminate or reduce amounts payable pursuant to this
Section 2.13 in the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to
pay all reasonable costs and expenses incurred by any Lender in connection with any such
designation or assignment.

          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

26

 

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

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

          SECTION 2.16. 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

27

 

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.

          SECTION 2.17. Defaulting Lenders. Notwithstanding any provision of this Agreement to
the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply
for so long as such Lender is a Defaulting Lender:

     (a) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting
Lender pursuant to Section 2.03(a);

     (b) the Commitment and Revolving Credit Advances of such Defaulting Lender shall not be
included in determining whether the Required Lenders have taken or may take any action hereunder
(including any consent to any amendment or waiver pursuant to Section 8.01, other than those which
require the consent of all Lenders or of each affected Lender);

     (c) the Borrower may, subject to the requirements of Sections 8.04 and 8.07, substitute for
such Defaulting Lender another financial institution, which financial institution shall be an
Eligible Assignee and shall assume the Commitments of such Defaulting Lender and purchase the
Revolving Credit Advances held by such Defaulting 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 Defaulting 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;

     (d) to the extent the Agent receives any payments or other amounts for the account of a
Defaulting Lender, such Defaulting Lender shall be deemed to have requested that the Agent use such
payment or other amount to fulfill such Defaulting Lender’s previously unsatisfied obligations to
fund a Revolving Credit Advance or any other unfunded payment obligation of such Defaulting Lender
under Section 2.02(d), 2.12(e) or 7.05;

     (e) no Lender shall be deemed to have consented to increase its Commitment pursuant to Section
2.04(c) unless that Lender shall have affirmatively given consent in accordance with that Section;
and

     (f) for the avoidance of doubt, the Borrower shall retain and reserve its other rights and
remedies respecting each Defaulting Lender.

In the event that the Agent and the Borrower each agrees that a Defaulting Lender has adequately
remedied all matters that caused such Lender to be a Defaulting Lender, such Lender shall purchase
at par on a ratable basis such of the Revolving Credit Advances of the other Lenders as the Agent
shall determine may be necessary in order for such Lender to hold such Revolving Credit Advances in
accordance with its Pro Rata Share.

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

treat the payee in respect of any Revolving Credit Advance as the owner thereof until the Agent
receives and accepts an Assignment and Acceptance entered into by the Lender that is the payee in
respect of such Revolving Credit Advance, as assignor, and an Eligible Assignee, as assignee, as
provided in Section 8.07; (ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the advice of such

Agreement on the part of the Borrower or to inspect the property (including the books and records)

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

40

 

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), solely in its capacity as Agent hereunder, ratably
according to the respective principal amounts of their respective Revolving Credit Advances (or if
no Revolving Credit Advances are at the time outstanding or if any Revolving Credit Advances are
owing to Persons that are not Lenders, ratably according to the respective amounts of their
Commitments), from and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that
may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out
of any Loan Document or any action taken or omitted by the Agent under any Loan Document,
provided that no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each
Lender agrees to reimburse the Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including reasonable counsel fees) incurred by the Agent, solely in its
capacity as Agent hereunder, 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 $500,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed
to and become vested with all the rights, powers, discretion, privileges and duties of the retiring
Agent, and the retiring Agent shall be

41

 

discharged from its duties and obligations under this Agreement. After any retiring Agent’s
resignation or removal hereunder as Agent, the provisions of this Article VII shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent under this
Agreement.

          SECTION 7.07. Co-Syndication Agents and Documentation Agent. None of the Lenders
identified in this Agreement as a Co-Syndication Agent or a Documentation Agent shall have any
right, power, obligation, liability, responsibility or duty under this Agreement other than those
applicable to all Lenders as such. Without limiting the foregoing, none of such Lenders shall have
or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same
acknowledgments with respect to such Lenders as it makes with respect to the Agent in Section 7.04.

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

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

43

 

for purposes of the Loan Documents. Each Lender agrees (A) to notify the Agent in writing
(including by electronic communication) from time to time of such Lender’s e-mail address to which
the foregoing notice may be sent by electronic transmission and (B) that the foregoing notice may
be sent to such e-mail address.

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

                    (iv) The parties hereto acknowledge and agree that the distribution of the Communications and
other material through an electronic medium is not necessarily secure and that there are
confidentiality and other risks associated with such distribution. EACH OF THE PARTIES HERETO
ACKNOWLEDGES AND AGREES AS FOLLOWS: (A) THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”; (B)
THE AGENT PARTIES DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE
ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE
COMMUNICATIONS; (C) NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT
LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF
THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN
CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM; AND (D) IN NO EVENT SHALL THE AGENT OR ANY OF
ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR
REPRESENTATIVES (COLLECTIVELY, THE “AGENT PARTIES”) HAVE ANY LIABILITY TO THE BORROWER, ANY
LENDER OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT LIMITATION, DIRECT
OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT,
CONTRACT OR OTHERWISE) ARISING OUT OF THE BORROWER’S OR THE AGENT’S TRANSMISSION OF COMMUNICATIONS
THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND IN A FINAL
NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH
AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

                    (v) This clause (b) shall terminate on the date that neither Barclays nor any of its
Affiliates is the Agent under this Agreement.

          SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender or the Agent
to exercise, and no delay in exercising, any right hereunder or under any

44

 

Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such
right preclude any other or further exercise thereof or the exercise of any other right. The
remedies herein provided are cumulative and not exclusive of any remedies provided by law.

          SECTION 8.04. Costs and Expenses.

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

          (b) The Borrower agrees to indemnify, to the extent legally permissible, and hold harmless the
Agent and each Lender and each of their Affiliates and their officers, directors, employees, agents
and advisors (each, an “Indemnified Party”) from and against any and all claims, damages,
losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of
counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of, or in connection with the preparation for a
defense of, any investigation, litigation or proceeding arising out of, related to or in connection
with (i) the Loan Documents, any of the transactions contemplated herein or therein or the actual
or proposed use of the proceeds of the Revolving Credit Advances or (ii) the actual or alleged
presence of Hazardous Materials on any property of the Borrower or any of its Subsidiaries or any
Environmental Action relating in any way to the Borrower or any of its Subsidiaries, in each case
whether or not such investigation, litigation or proceeding is brought by the Borrower, its
directors, shareholders or creditors or an Indemnified Party or any other Person or any Indemnified
Party is otherwise a party thereto and whether or not the transactions contemplated hereby are
consummated, except to the extent such claim, damage, loss, liability or expense is found in a
final, non-appealable judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party’s gross negligence or willful misconduct; provided that upon receipt of
notice of any such matter by a representative of the Agent or any Lender, as applicable, having
primary responsibility for the relationship between the Borrower and the Agent or such Lender, as
applicable, the Agent or such Lender, as applicable, shall promptly notify the Borrower to the
extent permitted by applicable law. The Borrower shall have no liability for any settlement
effected without its prior written consent, which consent shall not be unreasonably withheld or
delayed. 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,

45

 

employees, attorneys and agents, on any theory of liability, for special, indirect,
consequential or punitive damages arising out of or otherwise relating to the Loan Documents, any
of the transactions contemplated herein or therein or the actual or proposed use of the proceeds of
the Revolving Credit Advances.

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

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

          SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the continuance of
any Event of Default and (ii) the making of the request or the granting of the consent specified by
Section 6.01 to authorize the Agent to declare the Revolving Credit Advances due and payable
pursuant to the provisions of Section 6.01, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional or final) at any
time held and other indebtedness at any time owing by such Lender or such Affiliate to or for the
credit or the account of the Borrower against any and all of the obligations of the Borrower now or
hereafter existing under the Loan Documents and any Note held by such Lender, whether or not such
Lender shall have made any demand under this Agreement or such Note and although such obligations
may be unmatured. Each Lender agrees promptly to notify the Agent and the Borrower after any such
set-off and application, provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Lender and its Affiliates under this
Section are in addition to other rights and remedies (including, without limitation, other rights
of set-off) that such Lender and its Affiliates may have.

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

46

 

          SECTION 8.07. Assignments, Designations and Participations. (a) Each Lender may (i)
with the prior consent of the Agent (which consent shall not be unreasonably withheld, and which
consent shall not be required in the event of an assignment or grant pursuant to Sections 8.07(g)
or (h) or an assignment to any other Lender, an Affiliate of a Lender, or an Approved Fund) and
(ii) for so long as no Default has occurred and is continuing, with the consent of the Borrower
(which consent shall not be unreasonably withheld, and which consent shall not be required in the
event of an assignment or grant pursuant to Sections 8.07(g) or (h) or an assignment to any other
Lender, an Affiliate of a Lender, or an Approved Fund), 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 (A) each such assignment shall be of a constant, and
not a varying, percentage of all rights and obligations under this Agreement, (B) 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, (C) each such
assignment shall be to an Eligible Assignee, and (D) 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, (1) 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 (2) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto).

          (b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder
and the assignee thereunder confirm to and agree with each other and the other parties hereto as
follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender
makes no representation or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any lien or security interest created or purported to be created under or in
connection with, this Agreement or any other instrument or document furnished pursuant hereto;
(ii) such assigning Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or observance by the
Borrower of any of its obligations under this Agreement or any other instrument or document
furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this
Agreement, together with copies of the financial statements referred to in Section 4.01 and such
other documents and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and
without reliance upon the Agent, such assigning Lender or any

47

 

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

48

 

consent to any departure by the Borrower therefrom, except to the extent that such amendment,
waiver or consent would (A) reduce the principal of, or interest on, the Revolving Credit Advances
or any fees or other amounts payable hereunder, or (B) increase the Commitments, in each case to
the extent subject to such participation, or postpone any date fixed for any payment of principal
of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder,
in each case to the extent subject to such participation. Each participant shall be entitled to
the benefits and subject to the exclusions, in each case, as if it were a Lender, of Sections 2.10,
2.11(a) and 2.13 to the same extent as if it were a Lender and had acquired its interest under this
Agreement by an assignment made pursuant to this Section 8.07, provided, however,
that (i) such participant complies with the requirements of Section 2.13(e) and (ii) in no event
shall the Borrower be obligated to make any payment with respect to such Sections that is greater
than the amount that the Borrower would have otherwise made had no participations been sold under
this Section 8.07(e).

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

          (g) Notwithstanding any other provision set forth in this Agreement, any Lender may at any
time 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 Person (other than the Borrower or an Affiliate of the Borrower), including, without
limitation, any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of
the Federal Reserve System.

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

49

 

          (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.

50

 

          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 the Agent or such Lender, (d)
as requested or required by any state, federal or foreign authority or examiner regulating banks,
other financial institutions or banking, (e) in connection with the exercise of any remedies
hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights
hereunder, (f) on a confidential basis to any Lender’s direct or indirect contractual

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

          SECTION 8.10. Execution in Counterparts; Integration. This Agreement may be executed

Notes in any New York State or federal court. Each of the parties hereto hereby irrevocably

          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

enforcement thereof.

the Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

          IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government
fight the funding of terrorism and money laundering activities, Federal law requires all financial
institutions to obtain, verify, and record information that identifies each person or entity that
opens an account, including any deposit account, treasury management account, loan, other extension
of credit, or other financial services product. What this means for the Borrower: When the
Borrower opens an account, the Agent and the Lenders will ask for the Borrower’s name, tax
identification number, business address, and other information that will allow the Agent and the
Lenders to identify the Borrower. The Agent and the Lenders may also ask to see the Borrower’s
legal organizational documents or other identifying documents.

          SECTION 8.14. Severability. In the event any one or more of the provisions contained
in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein shall not in any way be
affected or impaired thereby.

          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 Status 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.

          “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 and Applicable Percentage shall be determined in accordance with the
foregoing table based on the Borrower’s Status as determined from its then-current Moody’s and S&P
Ratings. The credit rating in effect on any date for the purposes of this Schedule is that in
effect at the close of business on such date. If at any time the Borrower does not have both a
Moody’s Rating and an S&P Rating, Level V Status shall exist; provided, however,
that if the credit rating system of Moody’s or S&P shall change, or if either such rating agency
shall cease to be in the business of rating corporate debt obligations, the Borrower and the
Lenders shall negotiate in good faith to amend this Schedule to reflect such changed rating system
or the unavailability of ratings from such rating agency and, pending the effectiveness of any such
amendment, the applicable Status for the Borrower shall be the Borrower’s Status most recently in
effect prior to such change or cessation.

          Except as specifically provided above in this Schedule, in the event that a split occurs
between the two ratings, the pricing shall be based upon (x) the higher of the two ratings then
applicable if all such ratings shall be in Level I Status, Level II Status, Level III Status or
Level IV Status and (y) the lower of the two ratings if any of such ratings shall be in Level V
Status. However, if (x) the split is greater than one level and the lowest rating shall be in
Level III Status or Level IV Status, then the pricing shall be based upon the rating one level
above the lower of the two ratings and (y) the split is greater than one level and the lowest
rating shall be in Level V Status, then pricing shall be based upon Level V Status.

“Lender”) for the account of its Applicable Lending Office on the Termination Date (each as
defined in the Credit Agreement referred to below), the principal sum of U.S.$[amount of
the Lender’s Commitment in figures] or, if less, the aggregate principal amount of the

Lender and such other lenders outstanding on the Termination Date.

          The Borrower promises to pay interest on the unpaid principal amount of each Revolving Credit
Advance from the date of such Revolving Credit Advance until such principal amount is paid in full,
at such interest rates, and payable at such times, as are specified in the Credit Agreement.

          Both principal and interest are payable in lawful money of the United States of America to
Barclays Bank PLC, as Agent, at 200 Park Avenue, New York, NY 10166, Account No. 050-019104,

this Promissory Note, and (ii) contains provisions for acceleration of the maturity hereof upon the
happening of certain stated events and also for prepayments on account of principal hereof prior to
the maturity hereof upon the terms and conditions therein specified.

EXHIBIT C — FORM OF

ASSIGNMENT AND ACCEPTANCE

          Reference is made to the Two-Year Credit Agreement dated as of April 29, 2009 (as amended or
modified from time to time, the “Credit Agreement”) among The Detroit Edison Company, a
Michigan corporation (the “Borrower”), the Lenders (as defined in the Credit Agreement) and
Barclays Bank PLC, as agent for the Lenders (the “Agent”). Terms used but not otherwise
defined herein have the respective meanings assigned to such terms in the Credit Agreement.

          The “Assignor” and the “Assignee” referred to on Schedule 1 hereto agree as follows:

          1. The Assignor hereby sells and assigns to the Assignee, and the Assignee hereby purchases
and assumes from the Assignor, an interest in and to the Assignor’s rights and obligations under
the Credit Agreement as of the date hereof (if any) equal to the percentage interest specified on
Schedule 1 hereto of all outstanding rights and obligations under the Credit Agreement. After
giving effect to such sale and assignment, the Assignee’s Commitment and the amount of the
Revolving Credit Advances owing to the Assignee under the Credit Agreement will be as set forth on
Schedule 1 hereto.

          2. The Assignor (i) represents and warrants that it is the legal and beneficial owner of the
interest being assigned by it hereunder and that such interest is free and clear of any adverse
claim; (ii) makes no representation or warranty and assumes no responsibility with respect to any

execution, legality, validity, enforceability, genuineness, sufficiency or value of the Credit
Agreement or any other instrument or document furnished pursuant thereto; (iii) 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 the
Credit Agreement or any other instrument or document furnished pursuant thereto; and (iv) attaches
the Note or Notes held by the Assignor, if any, and requests that the Agent exchange such Note or
Notes for a new Note or Notes payable to the order of the Assignee in an amount equal to the
Commitment assumed by the Assignee pursuant hereto and the Credit Agreement or new Notes payable to
the order of the Assignee in an amount equal to the Commitment assumed by the Assignee pursuant
hereto and the Credit Agreement and the Assignor in an amount equal to the Commitment retained by
the Assignor under the Credit Agreement, respectively, as specified on Schedule 1 hereto.

          3. The Assignee (i) confirms that it has received a copy of the Credit Agreement, together
with copies of the financial statements referred to in Section 4.01 thereof and such other
documents and information as it has deemed appropriate to make its own credit analysis and decision
to enter into this Assignment and Acceptance; (ii) agrees that it will, independently and without
reliance upon the Agent, the Assignor or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Credit Agreement; (iii) confirms that it is an Eligible
Assignee; (iv) appoints and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers and discretion under the Credit Agreement as are delegated to the Agent by the
terms thereof, together with such powers and discretion as are

 

 

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

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

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

          6. Upon such acceptance and recording by the Agent, from and after the Effective Date, the
Agent shall make all payments under the Credit Agreement, and the Notes in respect of the interest
assigned hereby (including, without limitation, all payments of principal, interest and Facility
Fees with respect thereto) to the Assignee. The Assignor and Assignee shall make all appropriate
adjustments in payments under the Credit Agreement, and the Notes for periods prior to the
Effective Date directly between themselves.

          7. This Assignment and Acceptance shall be governed by, and construed in accordance with, the
laws of the State of New York.

          8. This Assignment and Acceptance 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 Schedule 1 to this Assignment and Acceptance by telecopier
shall be effective as delivery of a manually executed counterpart of this Assignment and
Acceptance.

          IN WITNESS WHEREOF, the Assignor and the Assignee have caused Schedule 1 to this Assignment
and Acceptance to be executed by their officers thereunto duly authorized as of the date specified
thereon.

EXHIBIT E-1 — FORM OF

OPINION OF GENERAL COUNSEL TO THE BORROWER

April 29, 2009

To each of the Lenders party to the

Credit Agreement defined below

The Detroit Edison Company

Ladies and Gentlemen:

          This opinion is furnished to you pursuant to Section 3.01(g)(v) of the Two-Year Credit
Agreement (the “Credit Agreement”), dated as of April 29, 2009, among The Detroit Edison
Company (the “Borrower”), the financial institutions from time to time parties thereto as
“Lenders” and Barclays Bank PLC (the “Agent”), as agent for said Lenders. Terms defined in
the Credit Agreement are used herein as therein defined.

          I am the General Counsel of the Borrower, and have acted as counsel for the Borrower in
connection with the preparation, execution and delivery of the Loan Documents.

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

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

     (ii) The other documents furnished by the Borrower pursuant to Article III of the
Credit Agreement.

     (iii) The Restated Articles of Incorporation of the Borrower and all amendments thereto
(the “Charter”).

     (iv) The Bylaws of the Borrower and all amendments thereto (the “Bylaws”).

     (v) A certificate from the State of Michigan attesting to the continued corporate
existence and good standing of the Borrower.

In addition, I have examined the originals or copies certified to my satisfaction, of such other
corporate records of the Borrower, certificates of public officials and of officers of the
Borrower, and agreements, instruments and other documents, as I have deemed necessary as a basis
for the opinions expressed below. As to questions of fact material to such opinions, I have, when
relevant facts were not independently established by me, relied upon certificates of public
officials. I have assumed the due execution and delivery, pursuant to due authorization, of the
Credit Agreement by the Lenders and the 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. The Borrower 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 the Borrower of the Loan Documents to which it
is party, and the consummation of the transactions contemplated thereby, are within the Borrower’s
corporate powers, have been duly authorized by all necessary corporate action, and do not
contravene (i) the Charter or the Bylaws, (ii) any law, rule or regulation applicable to the
Borrower, or (iii) any contractual restriction binding on or affecting the Borrower.

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

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

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

          6. In a properly presented case, a Michigan court or a federal court sitting in the State of
Michigan applying Michigan choice of law rules should give effect to the choice of law provisions
of the Loan Documents and should hold that the 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 the Credit Agreement, 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 Loan Documents would be, under the laws of
the State of Michigan, legal, valid and binding obligations of the Borrower, enforceable against
the Borrower in accordance with their respective terms.

          8. Neither the Borrower nor any of its 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;

 

 

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

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

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

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

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

          This opinion letter is rendered to you in connection with the above-described transaction.
This opinion letter may not be relied upon by you for any other purpose, or relied upon by any
other person or entity without my prior written consent (provided, that this opinion letter may be
furnished to and relied upon by a subsequent assignee of, or participant under, the Credit
Agreement and a Note, if any, solely for the purpose of such assignment or participation, subject
to the assumptions, limitations and qualifications, set forth herein, without any prior written
consent). I undertake no duty to inform you or any assignee or participant of events occurring
subsequent to the date hereof.

Very truly yours,

 

 

EXHIBIT E-2 — FORM OF

OPINION OF HUNTON & WILLIAMS LLP

April 29, 2009

To each of the Lenders party to the

Credit Agreements defined below

DTE Energy Company

The Detroit Edison Company

Michigan Consolidated Gas Company

Ladies and Gentlemen:

          This opinion is delivered to you pursuant to Section 3.01(g)(v) of each of (i) the Two-Year
Credit Agreement (the “DTE Credit Agreement”), dated as of April 29, 2009, among DTE Energy
Company (“DTE”), the financial institutions from time to time parties thereto as “Lenders”
and Citibank, N.A. (“Citibank”), as agent for said Lenders, (ii) the Two-Year Credit
Agreement (the “DECO Credit Agreement”), dated as of April 29, 2009, among The Detroit
Edison Company (“DECO”), the financial institutions from time to time parties thereto as
“Lenders” and Barclays Bank PLC (“Barclays”), as agent for said Lenders, and (iii) the
Two-Year Credit Agreement (the “MichCon Credit Agreement”, and, together with the DTE
Credit Agreement and the DECO Credit Agreement, the “Credit Agreements”), dated as of April
29, 2009, among Michigan Consolidated Gas Company (“MichCon”), the financial institutions
from time to time parties thereto as “Lenders” and JPMorgan Chase Bank, N.A. (“JPMCB”), as
agent for said Lenders. Terms used herein which are defined in each Credit Agreement shall have
the respective meanings set forth in each Credit Agreement, unless otherwise defined herein.

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

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

 

 

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

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

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

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

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

          We express no opinion with respect to: (a) the effect of any provision of the Loan Documents
that is intended (i) to establish any standard as the measure of the performance by any party
thereto of such party’s obligations of good faith, diligence, fair dealing, reasonableness or care
or (ii) to permit modification thereof only by means of an agreement in writing signed by the
parties thereto; (b) the effect of any provision of the Loan Documents insofar as it provides that
any Person purchasing a participation from a Lender or other Person may exercise set-off or similar
rights with respect to such participation or that any Lender or other Person may exercise set-off
or similar rights other than in accordance with applicable law; (c) the effect of any provision of
the Loan Documents imposing penalties or forfeitures; (d) the effect of any provision of the Loan
Documents relating to indemnification or exculpation in connection with

 

 

violations of any securities laws or relating to indemnification, contribution or exculpation
in connection with willful, reckless or criminal acts or gross negligence of the indemnified or
exculpated Person or the Person receiving contribution; (e) any provision of the Loan Documents
which purports to provide for a waiver by the Borrowers of any immunity, defense or right which may
be available to the Borrowers; and (f) any provision of the Loan Documents which purports to
establish an evidentiary standard for determinations by any Person.

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

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

          This opinion letter is rendered to you in connection with the above-described transactions.
This opinion letter may not be relied upon by you for any other purpose, or relied upon by any
other person or entity without our prior written consent (provided, that this opinion Letter may be
furnished to and relied upon by a subsequent assignee of, or participant under, the Credit
Agreements and a Note, if any, solely for the purpose of such assignment or participation, subject
to the assumptions, limitations and qualifications set forth herein without our prior written
consent). This opinion letter speaks only as of its date, there is no assurance that it will be
correct as of any date after its date, and we undertake no duty to inform you or any assignee or
participant of events occurring subsequent to the date hereof.

Very truly yours,

dated as of April 29, 2009 (as amended or modified from time to time, the “Agreement”)

          4. Schedule 1 attached hereto sets forth financial data and computations evidencing the

obligations of a Lender thereunder, (iv) it has received a copy of the Credit Agreement, together
with copies of the most recent financial statements delivered pursuant to Section 5.01 thereof, as
applicable, and such other documents and information as it has deemed appropriate to make its own

respect to the representations and warranties set forth in (x) the last sentence of Section 4.01(e)
