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

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. 

  
 17 









 (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.

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 Energy Credit Agreement and the DTE Gas Credit Agreement (as such term is defined in each of the respective Credit Agreements) must be

(y) be increased pursuant to Section 2.04(c) of each Credit Agreement by an aggregate amount in excess of $200,000,000. 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 

  
 19 









 
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 Business Day of each
March, June, September and December during such periods and on the date such Base Rate Advance shall be Converted or paid in full. 
 (ii) Eurodollar Rate Advances. During such periods as such Revolving Credit Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such Revolving
Credit Advance to the sum of (x) the Eurodollar Rate for such Interest Period for such Revolving Credit Advance plus (y) the Applicable Margin in effect from time to time, payable in arrears on the last day of such Interest Period
and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period and on the date such Eurodollar Rate Advance shall be Converted
or paid in full. 
 (b) Default Interest. (i) Upon the occurrence and during the continuance of an Event of Default,
the Borrower shall pay interest on the unpaid principal amount of each Revolving Credit Advance owing to each Lender, payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum equal at all times to
2% per annum above the rate per annum required to be paid on such Revolving Credit Advance pursuant to clause (a)(i) or (a)(ii) above, and (ii) the Borrower shall pay, to the fullest extent permitted by law, 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. 

  
 20 









 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 “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, 

  
 21 









 (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 be substantially in the
form of Exhibit H hereto, and shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Revolving Credit Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate
Advances, the duration of the initial Interest Period for each such Eurodollar Rate Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower. 
 SECTION 2.09. Prepayments of Revolving Credit Advances. 
 (a) Optional
Prepayment. The Borrower may on any Business Day, upon notice given to the Agent substantially in the form of Exhibit I hereto, not later than 11:00 A.M. (New York City time), (i) on the same day for Base Rate Advances and
(ii) on the third 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 

  
 22 









 
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 Person of agreeing to make or making, funding or maintaining
Revolving Credit Advances, including as a result of any tax, levy, impost, deduction, fee, assessment, duty, charge or withholding, and all liabilities with respect thereto, imposed on its loans, loan principal, commitments, or other obligations, or
its deposits, reserves, other liabilities or capital attributable thereto, excluding for purposes of this Section 2.10 any such increased costs resulting from Taxes, amounts excluded from Taxes pursuant to Section 2.13, and Other Taxes,
then the Borrower shall from time to time, upon demand by such Person (with a copy of such demand to the Agent), pay to the Agent on its own account or for the account of such Person, as applicable, additional amounts sufficient to compensate such
Person, for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the Agent by such Person, 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 or liquidity required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such
capital or liquidity 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 or liquidity 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 $3,500 administrative fee. 

  
 23 









 (d) If any Lender requests compensation under this Section 2.10, then such Lender
shall, if requested by the Borrower, 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. 

(e) For purposes of this Section 2.10, and notwithstanding anything herein to the contrary, (i) the Dodd-Frank Wall Street
Reform and Consumer Protection Act and all requests, rules, requirements, guidelines and directives thereunder or issued in connection therewith or in implementation thereof and (ii) all requests, rules, guidelines, requirements and directives
promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case
be deemed to have been enacted, adopted and issued after the date hereof, regardless of the date enacted, adopted, issued or implemented. 
 (f) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that,
the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred more than 270 days prior to the date that such Lender notifies the Borrower of the circumstances giving rise to such increased costs
and of such Lender’s intention to claim compensation therefor; provided further that, if the circumstance giving rise to such increased costs is retroactive, then the 270-day period referred to above shall be extended to include the
period of retroactive effect thereof. 
 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. 

  
 24 









 (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 Assumption 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 Assumption, 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 Assumption 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. 

  
 25 









 (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, fees, assessments, duties, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender and the Agent, (i) any and all present or future taxes, levies, imposts, deductions, fees, assessments, duties, charges or withholdings imposed on its net income, and franchise taxes imposed
on it in lieu of net income taxes, (x) 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 (y), in the case of each Lender, by the jurisdiction of such
Lender’s Applicable Lending Office or any political subdivision thereof and (ii) any United States withholding taxes imposed by FATCA (all such non-excluded taxes, levies, imposts, deductions, fees, assessments, duties, 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”). 

  
 26 









 (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 Assumption 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) If a payment made to a Lender hereunder would be subject to United States withholding tax imposed by FATCA if such Lender were to
fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to the Borrower and the Agent at the time or
times prescribed by law and at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such
additional documentation reasonably requested by the Borrower or the Agent as may be necessary for the 

  
 27 









 
Borrower and the Agent to comply with their obligations under FATCA and to determine that such Lender has or has not complied with such Lender’s obligations under FATCA or to determine the
amount to deduct and withhold from such payment. Solely for purposes of this clause (f), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

(g) 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, fees, assessments, duties, 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 except as may be required by Section 2.10. 
 (h) 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. 
 (i) 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 $3,500 administrative fee.

 (j) 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. 
 (k) 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 

  
 28 









 
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. 

(l) Each Lender shall severally indemnify the Agent for any taxes, levies, imposts, deductions, fees, assessments, duties, charges or
withholdings, and all liabilities with respect thereto, (but, in the case of any Taxes or Other Taxes, only to the extent that the Borrower has not already indemnified the Agent for such Taxes or Other Taxes and without limiting the obligation of
the Borrower to do so) attributable to such Lender that are paid or payable by the Agent in connection with this Agreement and any reasonable expenses arising therefrom or with respect thereto, whether or not such amounts were correctly or legally
imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.13(l) shall be paid within 30 days after the Agent delivers to the applicable Lender a certificate stating the amount so paid or payable by the
Agent. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. 
 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 general corporate purposes 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. 

  
 29 









 (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 Assumption 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 $3,500 administrative fee; 

  
 30 









 (d) to the extent the Agent receives any payments or other amounts for the account of a
Defaulting Lender under the Loan Documents, 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, whereupon such Lender shall cease to be a Defaulting Lender. For the purposes of clarity, in the event any Defaulting Lender is
reinstated as a non-Defaulting Lender in accordance with the terms hereof (i) no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender, and
(ii) except to the extent otherwise expressly agreed by the affected parties, such reinstatement shall not constitute a waiver or release of any claim of any party hereunder arising from such Lender having been a Defaulting Lender.

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 

  
 42 









 
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,

the owner thereof until the Agent receives and accepts an Assignment and Assumption 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

inspect the property (including the books and records) of the Borrower; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of
any lien or security interest created or purported to be created under or in connection with, any Loan Document or any other instrument or document furnished pursuant hereto; and (vi) shall incur no liability under or in respect of this
Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier, telegram or telex) believed by it to be genuine and signed or sent by the proper party or parties. 

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

SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent or
any other Lender and based on the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent 

  
 43 









 
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 as determined in a final, non-appealable judgment by a court of competent jurisdiction. 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.
Upon any such resignation, 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, 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, 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.

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

 48 









 (c) If any payment or reallocation of principal of, or Conversion of, any Eurodollar Rate

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.

Advance or the use of the proceeds thereof; provided that, nothing contained in this paragraph shall limit the Borrower’s reimbursement and indemnity obligations set forth in this Section 8.04. For the avoidance of doubt, all
payments to which the Agent and the Lenders are expressly entitled under this Agreement, including without limitation amounts due under Sections 2.10, 2.11 and 2.13, if demanded in accordance with the terms of this

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

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.

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 Assumption 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 Assumption,
together with any Note subject to such assignment and a processing and recordation fee of $3,500, which fee may be waived by the Agent in its sole discretion if such assignment is to an Affiliate of the assigning Lender. Upon such execution,

party hereto). 
 (b) By executing and delivering an Assignment and Assumption, the Lender assignor thereunder and the assignee

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.

assignment, the Agent shall, if such Assignment and Assumption has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Assumption, (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 Assumption 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 Assumption and shall otherwise be in substantially the form of Exhibit A hereto. 

  
 51 









 (d) The Agent shall maintain at its address referred to in Section 8.02 a copy of each
Assignment and Assumption 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) (it being understood that the documentation required under Section 2.13(e) shall be delivered to the participating Lender). Each Lender that sells a participation shall, acting solely for this purpose as an agent of the
Borrower, maintain a register on which it enters the name and address of each participant and the principal amounts (and stated interest) of each participant’s interest in the obligations under this Agreement (the “Participant
Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any participant or any information relating to a participant’s
interest in the obligations under this Agreement) except to the extent that such disclosure is necessary to establish that such interest is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in
the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any
notice to the contrary. 

  
 52 









 (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 or any other central bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System, provided
that no such security interest shall release such Lender from its obligations hereunder or substitute any such other Person for such Lender as a party hereto. 
 (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. 

  
 53 









 (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 

  
 54 









 
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 the Borough of Manhattan in the county of 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. 

  
 55 









 SECTION 8.13. USA Patriot Act Notification. The following notification is provided to
the Borrower pursuant to Section 326 of the PATRIOT Act: 
 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. 

SECTION 8.15. No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby
(including in connection with any amendment, waiver or other modification hereof or of any other Loan Document or any syndication of the credit facility provided hereunder), the Borrower acknowledges and agrees that: (i) (A) the arranging
and other services regarding this Agreement provided by the Agents and the Arrangers are arm’s-length commercial transactions between the Borrower and its Affiliates, on the one hand, and the Agents and the Arrangers, and each of their
respective Affiliates, on the other hand, (B) it has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (C) it is capable of evaluating, and understands and accepts, the
terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents; (ii) (A) each of the Agents, the Arrangers and the Borrower has been acting solely as a principal and, except as expressly agreed in
writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for any other party hereto, any Affiliates of any other party hereto, or any other Person and (B) none of the Agents, the Arrangers
or the Borrower has any obligation to each other or to their respective Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; and (iii) the Agents,
the Arrangers and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and none of the Agents or the Arrangers has any obligation to disclose
any of such interests to the Borrower or its Affiliates. To the fullest extent permitted by law, the Agents, the Arrangers and the Borrower hereby waive and release any claims that they may have against each other with respect to any breach or
alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby. Each of the Agent and the Lenders acknowledges and agrees that it has consulted its own legal, accounting, regulatory and tax advisors
to the extent it has deemed appropriate.

 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 A1 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 A2 or better or the Borrower’s S&P Rating is A 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 A3 or better or the Borrower’s S&P Rating is A- 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 Baa1 or better or the Borrower’s S&P Rating is BBB+ or better. 
 “Level V
Status” exists at any date if on such date, (i) the Borrower has not qualified for Level I Status, Level II Status, Level III Status or Level IV 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 VI Status” exists at any date if on such date,
(i) the Borrower has not qualified for Level I Status, Level II Status, Level III Status, Level IV Status or Level V 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 VII Status” exists at any date if, on such date, the Borrower has not qualified for
Level I Status, Level II Status, Level III Status, Level IV Status, Level V Status or Level VI Status. 







 “Moody’s Rating” means, at any time, (i) 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, or (ii) if no rating has been 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, 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, (i) 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, or (ii) if no rating has been 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, 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, Level V Status, Level VI Status or Level VII 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 VII 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, Level IV Status, Level V Status or Level VI Status and (y) the lower of
the two ratings if any of such ratings shall be in Level VII Status. However, if (x) the split is greater than one level and the lowest rating shall be in Level III Status, Level IV Status, Level V Status or Level VI 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 VII Status, then pricing shall be based upon Level VII Status.

 The Borrower promises to pay interest on the unpaid principal amount of each Revolving Credit Advance from

 EXHIBIT E-1 - FORM OF 
 OPINION OF COUNSEL TO BORROWER 
 April 5, 2013 

To each of the Lenders party to the 
 Credit
Agreement defined below 
 DTE Electric Company 
 Ladies and Gentlemen: 
 This opinion is furnished to you pursuant to
Section 3.01(h)(v) of the Second Amended and Restated Five-Year Credit Agreement (the “Credit Agreement”), dated as of April 5, 2013, among DTE Electric 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 Associate General Counsel of DTE Energy, 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.

 EXHIBIT E-2 - FORM OF 
 OPINION OF HUNTON & WILLIAMS LLP 
 April 5, 2013 

To each of the Lenders party to the 
 Credit
Agreements defined below 
 DTE Energy Company 
 DTE Electric Company 
 DTE Gas Company 
 Ladies and Gentlemen: 
 This opinion is delivered to you pursuant to
Section 3.01(h)(v) of each of (i) the Second Amended and Restated Five-Year Credit Agreement (the “DTE Energy Credit Agreement”), dated as of April 5, 2013, among DTE Energy Company (“DTE”), the
financial institutions from time to time party thereto as “Lenders” and Citibank, N.A., as administrative agent for such Lenders, (ii) the Second Amended and Restated Five-Year Credit Agreement (the “DTE Electric Credit
Agreement”), dated as of April 5, 2013, among DTE Electric Company (f/k/a The Detroit Edison Company) (“DTE Electric”), the financial institutions from time to time party thereto as “Lenders” and Barclays
Bank PLC, as administrative agent for such Lenders, and (iii) the Second Amended and Restated Five-Year Credit Agreement (the “DTE Gas Credit Agreement” and, together with the DTE Energy Credit Agreement and the DTE Electric
Credit Agreement, the “Credit Agreements”), dated as of April 5, 2013, among DTE Gas Company (f/k/a Michigan Consolidated Gas Company) (“DTE Gas” and, together with DTE and DTE Electric, the
“Borrowers”), the financial institutions from time to time party thereto as “Lenders” and JPMorgan Chase Bank, N.A., as administrative agent for such 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 of the Credit Agreements. 
 In connection with this opinion
we have examined a copy of each Credit Agreement and each Note issued on the date hereof 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, without
independent investigation, and have assumed the correctness of, the representations of each Borrower set forth in each Credit Agreement and upon certificates of public officials and of officers and representatives of the Borrowers. 







 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 parties thereto, (b) the parties to the Loan
Documents 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 party thereto (i) have been duly authorized by all necessary entity action on its part, (ii) do not contravene its certificate of organization or
by-laws or similar governing documents 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) each of the Credit Agreements constitutes the valid and
legally binding obligation of the applicable Agent and the applicable Lenders party thereto. 
 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 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 Credit Agreements and the Notes will not violate any Federal or New York statute or any rule or regulation issued pursuant to any Federal or New York statute, in each case which, in
our experience and without independent investigation, is normally applicable to transactions of the type contemplated by the Loan Documents. 
 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 Credit Agreements or the Notes 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 Credit Agreements or the Notes 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 Credit Agreements or the Notes
imposing penalties or forfeitures; (d) the effect of any provision of the Credit Agreements or the Notes 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 Credit Agreements or the Notes 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 Credit Agreements or the Notes 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. 

To the extent that any opinion contained herein relates to the enforceability of the choice of New York law provisions of the Credit
Agreements and the Notes, we have, in rendering such opinion, relied solely upon New York General Obligations Law Section 5-1401 and have assumed that the Credit Agreements and the Notes are not entered into with a view to violate the laws of
the jurisdiction in which the contract is to be performed. Further, such opinion is subject to the qualification that such enforceability may be limited by important public policies of a more-interested jurisdiction. We express no opinion regarding
whether a court other than a court of or in the State of New York would give effect to a choice of New York law. 
 This opinion
is being delivered and should be understood with reference to customary practice. See “Statement on the Role of Customary Practice in the Preparation and Understanding of Third-Party Legal Opinions,” 63 BUS. LAW. 1277 (2008). 

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 or the Notes solely for the purpose of such assignment or participation, subject to the assumptions, limitations and qualifications set forth herein without our prior written consent, on the condition
and understanding that (i) we have no responsibility or obligation to consider the applicability or correctness of this opinion letter to any Person other than its addressees, (ii) any such reliance by a future assignee or participant must
be actual and reasonable under the circumstances existing at the time of assignment or participation and (iii) 







 
the knowledge of the addressees with respect to matters addressed in this opinion letter as of the date hereof shall be imputed to all future assignees and participants, including any changes in
law, facts or any other developments known to or reasonably knowable by such an assignee or participant at such time. 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,
