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 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.

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 DECO 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.

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.

(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 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.

(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.

(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 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 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);

(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.

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.

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 other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender.

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

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

(e) Each Lender may sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Revolving Credit Advances owing to it and any Note or Notes held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the owner of such Revolving Credit Advances for all purposes of this Agreement, (iv) the Borrower, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve

any amendment or waiver of any provision of this Agreement or any Note, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would (A) reduce the principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, or (B) increase the Commitments, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Revolving Credit Advances or any fees or other amounts payable hereunder, in each case to the extent subject to such participation. Each participant shall be entitled to the benefits 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.

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

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

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

SECTION 8.08. Confidentiality. Neither the Agent nor any Lender shall disclose any Confidential Information to any other Person without the consent of the Borrower, other than (a) to the Agent’s or such Lender’s Affiliates and their officers, directors, employees, agents and advisors and, as contemplated by Section 8.07(f), to actual or prospective assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from 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 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.

Applicable Margin (Base Rate)	1.000%	1.375%	1.625%	1.875%	2.250%

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 ▇▇▇▇▇’▇ 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 ▇▇▇▇▇’▇ 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 ▇▇▇▇▇’▇ 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 ▇▇▇▇▇’▇ 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.

“▇▇▇▇▇’▇ Rating” means, at any time, the rating issued by ▇▇▇▇▇’▇ 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 ▇▇▇▇▇’▇ 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 ▇▇▇▇▇’▇ Rating and an S&P Rating, Level V Status shall exist; provided, however, that if the credit rating system of ▇▇▇▇▇’▇ 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.

EXHIBIT E-1 - FORM OF
OPINION OF ASSOCIATE GENERAL COUNSEL TO THE BORROWER

April 29, 2009

To each of the Lenders party to the
Credit Agreement defined below

DTE Energy 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 DTE Energy Company (the “Borrower”), the financial institutions from time to time parties thereto as “Lenders” and Citibank, N.A. (the “Agent”), as agent for said Lenders. Terms defined in the Credit Agreement are used herein as therein defined.

I am the Associate 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.

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 & ▇▇▇▇▇▇▇▇ 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,
