Company executes and delivers to the 

  
 6 








 
Trustee a Company Order that such Global Debenture shall be so exchangeable and the transfer thereof so registrable or (iii) there shall have occurred and be continuing an Event of Default
or an event which, with the giving of notice or lapse of time, or both, would constitute an Event of Default with respect to the Debentures. Upon the occurrence in respect of a Global Debenture of any or more of the conditions specified in clause
(i), (ii) or (iii) of the preceding sentence, such Global Debenture may be exchanged for Debentures registered in the name of, and the transfer of such Global Debenture may be registered to, such Persons (including Persons other than the
Depositary and its nominees) as such Depositary, in the case of an exchange, and the Company, in the case of a transfer, shall direct. 
 (c) Each Debenture issued hereunder shall provide that the Company and, by its acceptance of a Debenture or a beneficial interest therein, the holder of, and any Person that acquires a beneficial interest
in, such Debenture agree that for United States federal, state and local tax purposes it is intended that such Debenture constitute indebtedness, and agree to treat the Debenture as indebtedness for United States federal income tax purposes.

 (d) The Debentures shall have such other terms and provisions as are set forth in the form of Debenture attached hereto as
Exhibit A (all of which incorporated by reference in and made a part of this Supplemental Indenture as if set forth in full at this place). 
 SECTION 204. Interest. 
 (a) Each Debenture will bear interest at the rate of
6.50% per annum (the “Coupon Rate”) from and including the original date of issuance until the principal thereof becomes due and payable, and on any overdue principal and, to the extent that payment of such interest is enforceable
under applicable law, on any overdue installment of interest at the Coupon Rate, compounded quarterly, payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year (each, an “Interest
Payment Date”), commencing on March 1, 2012 to the Person in whose name such Debenture or any predecessor Debenture is registered at the close of business on the relevant Regular Record Date, which will be the date fifteen calendar days
immediately preceding the applicable Interest Payment Date, except as otherwise provided pursuant to the provisions of Section 205 below. 
 (b) Subject to Section 205, any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on the Regular Record Date, and may
either be paid to the person in whose name the Debenture (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof
shall be given to the registered Holders of this series of Debentures not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange
on which the Debentures may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Original Indenture. The principal of and the interest on the Debentures shall be payable at the office or agency of
the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in any coin or currency of the United States of America which at the time of payment is legal tender for payment of public and private debts; provided,
however, that payment of interest may be 

  
 7 








 
made at the option of the Company by check mailed to the registered Holder at the close of business on the Regular Record Date at such address as shall appear in the Security Register.
Notwithstanding anything else contained herein, if a Global Debenture is held in book-entry form through the facilities of the Depositary, payments on the Global Debenture will be made to the Depositary or its nominee in accordance with arrangements
then in effect between the Trustee and the Depositary. 
 (c) The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months. Except as provided in the following sentence, the amount of interest payable for any period shorter than a full quarterly period for which interest is computed, will be computed on the basis of
the actual number of days elapsed per 30-day month. In the event that any date on which interest is payable on the Debentures is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a
Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with
the same force and effect as if made on the date that such interest otherwise would have been payable. 
 (d) Maturity or
redemption of a Debenture shall cause interest to cease to accrue on such Debenture subject to the Company’s obligation to pay interest on overdue amounts in accordance with Section 503 of the Original Indenture and the terms of this
Supplemental Indenture and the Debentures. 
 SECTION 205. Extension of Interest Payment Period. 

(a) So long as no Event of Default with respect to the Debentures has occurred and is continuing, the Company shall have the right, at
any time and from time to time during the term of the Debentures, to defer payments of interest by extending the interest payment period of such Debentures not exceeding 20 consecutive quarters (an “Extension Period”), during which
Extension Period no interest shall be due and payable; except that no Extension Period may extend beyond the Stated Maturity. To the extent permitted by applicable law, interest, the payment of which has been deferred because of the extension of the
interest payment period pursuant to this Section 205, will bear interest thereon at an annual rate of 6.50% compounded quarterly for each quarter of the Extension Period (“Compound Interest”). At the end of the Extension Period, the
Company shall pay all interest accrued and unpaid on the Debentures, including any Compound Interest (together, “Deferred Interest”) that shall be payable to the Holders in whose names the Debentures are registered in the Security Register
on the record date for the first Interest Payment Date after the end of the Extension Period. Before the termination of any Extension Period, the Company may shorten or further extend such period, provided that such period together with all such
further extensions thereof shall not exceed 20 consecutive quarters, or extend beyond the Stated Maturity of the Debentures. Upon the termination of any Extension Period and upon the payment of all Deferred Interest then due, the Company may
commence a new Extension Period, subject to the foregoing requirements. No interest shall be due and payable during an Extension Period, except at the end thereof, but the Company may prepay at any time all or any portion of the interest accrued
during an Extension Period. 

  
 8 








 (b) The Company shall give the Holders of the Debentures and the Trustee written notice of
its selection of such Extension Period or any shortening or extension thereof at least ten Business Days before the earlier of (x) the next succeeding Interest Payment Date, or (y) if the Debentures are then listed, the date the Company is
required to give notice to the NYSE or other applicable self-regulatory organization or to Holders of the Debentures of the record date or the Interest Payment Date. The quarter in which any notice is given pursuant to this paragraph (b) shall
be counted as one of the 20 quarters permitted in the maximum Extension Period permitted under paragraph (a). 
 ARTICLE THREE

 Redemption of the Debentures 
 SECTION 301. Optional Redemption at Par. 
 The Debentures are redeemable
prior to the Stated Maturity at the option of the Company (i) in whole or in part, from time to time, on or after March 1, 2016 or (ii) at any time prior to March 1, 2016, in whole but not in part, within 90 days following the
occurrence and continuation of a Tax Event, in either case at a redemption price (the “Par Redemption Price”) equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon (including Compound Interest, if any) to
the date of redemption. 
 The Company’s right to redeem the Debentures under clause (ii) of the preceding paragraph
shall be subject to the condition that if at the time there is available to the Company the opportunity to eliminate a Tax Event, within 90 days following the occurrence and continuation of such Tax Event, by taking some ministerial action
(“Ministerial Action”), such as filing a form or making an election, or pursuing some other similar reasonable measure that will have no adverse effect on the Company and will involve no material cost, the Company shall pursue such
measures in lieu of redemption; provided further, that the Company shall have no right to redeem the Debentures while the Company is pursuing any such Ministerial Action. 

SECTION 302. Optional Redemption Following a Rating Agency Event. 

The Debentures are redeemable at the option of the Company prior to March 1, 2016, in whole or in part, on one or more occasions at
any time following the occurrence and continuation of a Rating Agency Event, at a redemption price (the “Make-Whole Redemption Price”) equal to the sum of (i) the Make-Whole Amount, plus (ii) accrued and unpaid interest thereon
(including Compound Interest, if any) to the Redemption Date. The Make-Whole Redemption Price for the Debentures will never be less than 100% of the principal amount of the Debentures being redeemed plus accrued and unpaid interest on Debentures to
the Redemption Date. 
 “Rating Agency Event” means a change in the methodology published by any nationally recognized
statistical rating organization within the meaning of Section 3(a)(62) of the Exchange Act that currently publishes a rating for the Company in assigning equity credit to securities such as the Debentures, as such methodology was in effect on
November 28, 2011 (the “current criteria”), which change results in (i) the length of time for which such current criteria are 

  
 9 








 
scheduled to be in effect being shortened with respect to the Debentures, or (ii) a lower or higher equity credit being assigned by such rating agency to the Debentures as of the date of
such change than the equity credit that would have been assigned to the Debentures as of the date of such change by such rating agency pursuant to its current criteria. 
 “Make-Whole Amount” means the greater of (i) 100% of the principal amount of Debentures being redeemed and (ii) the sum of the present values of the remaining scheduled payments of
principal and interest on the Debentures (exclusive of interest accrued to the Redemption Date) being redeemed from the Redemption Date to December 1, 2016 (assuming solely for the purposes of this calculation that the principal amount of
Debentures to be redeemed is payable on December 1, 2016), discounted to the Redemption Date on a quarterly basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points. 

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment
Banker as having an actual or interpolated maturity comparable to the time period from the Redemption Date to December 1, 2016 that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of a comparable maturity to such time period. 
 “Comparable Treasury Price” means
with respect to any Redemption Date (i) the average of the Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations or (ii) if fewer than four such
Reference Treasury Dealer Quotations are obtained, the average of all such quotations. 
 “Independent Investment
Banker” means one of the Reference Treasury Dealers appointed by the Company. 
 “Reference Treasury Dealer”
means each of Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, and UBS Securities LLC, and one other primary U.S. Government securities dealer in the United States of America (“Primary Treasury
Dealer”) selected by Wells Fargo Securities, LLC or its affiliates, and their respective successors; provided, however, that if any of the foregoing or their affiliates shall cease to be a Primary Treasury Dealer, the Company shall substitute
therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotations” means, with respect to each
Reference Treasury Dealer, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by the Reference
Treasury Dealers at 3:30 p.m., New York City time, on the third business day preceding the Redemption Date. 
 “Treasury
Rate” means the rate per annum equal to the quarterly equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue calculated on the third business day preceding the Redemption Date, assuming a price for
the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. 

  
 10 









 SECTION 303. Redemption Procedures. 

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of
Debentures to be prepaid at its registered address. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest shall cease to accrue on such Debentures called for redemption. If the Debentures are only
partially redeemed pursuant to Section 301, the Debentures will be redeemed pro rata or by lot or by any other method utilized by the Trustee; provided that if, at the time of redemption, the Debentures are registered as a Global Debenture, the
Depositary shall determine, in accordance with its procedures, the principal amount of such Debentures held by each Depositary participant to be redeemed. The Redemption Price shall be paid prior to 12:00 noon, New York time, on the date
of such redemption or at such earlier time as the Company determines; provided that the Company shall deposit with the Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price is
to be paid. 
 SECTION 304. No Sinking Fund. 
 The Debentures are not entitled to the benefit of any sinking fund. 
 ARTICLE FOUR

 Covenant to List on Exchange 
 SECTION 401. Listing on an Exchange.

 Subordination of Debentures 

SECTION 501. Debentures Subordinate to Senior Indebtedness. The Company for itself, its successors and assigns, covenants and
agrees, and each Holder of Debentures issued, whether upon original issue or upon transfer or assignment thereof, by its acceptance thereof likewise covenants and agrees, that the payment of principal of and interest on each and all of the

principal of or interest on the Debentures shall be made by the Company. 
 (ii) Upon any payment or
distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or total or partial liquidation or reorganization of the Company, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings, all principal, premium, if any, and interest, if any, due upon all Senior Indebtedness shall first be paid in full, or payment thereof provided for in money or money’s
worth in accordance with its terms, before any payment is made on account of the principal of or interest on the indebtedness evidenced by the Debentures, and upon any such dissolution, winding-up, liquidation or reorganization, any payment or
distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Debentures under the terms of this Supplemental Indenture would be entitled, except for the provisions hereof, shall
(subject to the power of a court of competent jurisdiction to make other equitable provision reflecting the rights conferred by the provisions hereof upon the Senior Indebtedness and the holders thereof with respect to the Debentures and the Holders
thereof by a lawful plan of reorganization under applicable bankruptcy law), be paid by the Company or any receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, or by the Holders of the
Debentures if received by them, directly to the holders of Senior Indebtedness (pro rata to each such holder on the basis of the respective amounts of Senior Indebtedness held by such holder) or their representatives, to the extent necessary to pay
all Senior Indebtedness (including interest thereon) in full, in money or money’s worth, in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any
payment or distribution is made to the holders of the indebtedness evidenced by the Debentures. The consolidation of the Company with, or a merger of the Company into, another Person or the liquidation or dissolution of the Company following the
conveyance or transfer of its property as an entirety, or substantially as an entirety, to another Person upon the terms and conditions provided in Section 801 of the Original Indenture shall not be deemed a dissolution, winding-up, liquidation
or reorganization for the purposes of this Section 502(a). 
 (b) In the event that any payment or distribution of assets
of the Company of any kind or character not permitted by Section 502(a), whether in cash, property or securities, shall be received by the Trustee or the Holders of Debentures before all Senior Indebtedness is paid in full, or provision made
for such payment, in accordance with its terms, upon written notice to the 

  
 12 









 
Trustee or, as the case may be, such Holder, such payment or distribution shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of such Senior
Indebtedness or their representative or representatives, or to the Trustee or trustees under any indenture pursuant to which any instruments evidencing any of such Senior Indebtedness may have been issued, as their respective interests may appear,
for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all such Senior Indebtedness in full in accordance with its terms, after giving effect to any concurrent payment or distribution to the holders
of such Senior Indebtedness. Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 606 of the Original Indenture. In addition, nothing in this Article shall prevent the Company from making or
the Trustee from receiving or applying any payment in connection with the redemption of the Debentures if the first publication of notice of such redemption (whether by mail or otherwise in accordance with this Supplemental Indenture) has been made,
and the Trustee has received such payment from the Company, prior to the occurrence of any of the contingencies specified in this Section 502. 
 SECTION 503. Subrogation to Rights of Holders of Senior Indebtedness. From and after the payment in full of all Senior Indebtedness, the Holders of the Debentures (together with the holders of any
other indebtedness of the Company which is subordinate in right of payment to the payment in full of all Senior Indebtedness, which is not subordinate in right of payment to the Debentures and which by its terms grants such right of subrogation to
the holder thereof) shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of assets or securities of the Company applicable to the Senior Indebtedness until the Debentures shall be paid in full,
and, for the purposes of such subrogation, no such payments or distributions to the holders of Senior Indebtedness of assets or securities, which otherwise would have been payable or distributable to Holders of the Debentures, shall, as between the
Company, its creditors (other than the holders of Senior Indebtedness), and the Holders of the Debentures, be deemed to be a payment by the Company to or on account of the Senior Indebtedness, it being understood that the provisions of this Article
are and are intended solely for the purpose of defining the relative rights of the Holders of the Debentures, on the one hand, and the holders of the Senior Indebtedness, on the other hand, and nothing contained herein is intended to or shall impair
as between the Company, its creditors (other than the holders of Senior Indebtedness), and the Holders of the Debentures, the obligation of the Company, which is unconditional and absolute, to pay to the Holders of the Debentures the principal of
and interest on the Debentures as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the Holders of the Debentures and creditors of the Company (other than the holders of the Senior
Indebtedness), nor shall anything herein or therein prevent the Trustee or the Holders of Debentures from exercising all remedies otherwise permitted by applicable law upon default hereunder with respect to the Debentures subject to the rights of
the holders of Senior Indebtedness, under Section 502, to receive cash, property or securities of the Company otherwise payable or deliverable to the Trustee or the Holders of the Debentures or to a representative of such Holders, on their
behalf. 
 Upon any distribution or payment in connection with any proceedings or sale referred to in Section 502(a), the
Trustee and each Holder of the Debentures then Outstanding, shall be entitled to rely upon a certificate of the liquidating trustee or agent or other Person making any 

  
 13 









 
distribution or payment to the Trustee or such Holder for the purpose of ascertaining the holders of Senior Indebtedness entitled to participate in such payment or distribution, the amount of
such Senior Indebtedness or the amount payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. 
 SECTION 504. No Impairment of Subordination. Nothing contained in this Article or elsewhere in this Supplemental Indenture or the Debentures shall prevent at any time the Company from making
payments at any time of principal of or interest on the Debentures, except under the conditions described in Section 502 or during the pendency of any proceedings or sale therein referred to. 

SECTION 505. Trustee to Effectuate Subordination. Each Holder of Debentures by his acceptance thereof, whether upon original issue
or upon transfer or assignment, authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provisions in this Article and appoints the Trustee his attorney-in-fact for any
and all such purposes. 
 No rights of any present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Trustee or any Holder of the Debentures then Outstanding, or by any act or failure to act, in good faith, by any such holder, or
by any noncompliance by any such holder, with the terms, provisions and covenants of this Supplemental Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. 

Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the Holders of the Debentures, without incurring responsibility to the Holders of the Debentures and without impairing or releasing the subordination provided in this Article or the obligations of the
Holders of the Debentures to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner
Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company and any other Person. 

SECTION 506. Notice to Trustee. The Company shall give prompt written notice to the Trustee in the form of an Officers’
Certificate of any fact known to the Company which would prohibit the making of any payment of money to or by the Trustee in respect of the Debentures pursuant to the provisions of this Article. Notwithstanding the provisions of this Article or any
other provisions of this Supplemental Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Debentures pursuant to the
provisions of this Article, unless and until the Trustee shall have received at its Corporate Trust Office written notice thereof from the Company or a holder or holders of Senior Indebtedness or from any trustee therefor at least two Business Days
prior to such payment date; and, prior to the receipt of any such written notice, the Trustee, shall be entitled in all respects to assume that no such facts exist. 

  
 14 









 The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness or a trustee on behalf of any such holder. In the event that the
Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent
to the rights of such Person under this Article, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

SECTION 507. Reliance on Certificate of Liquidating Agent. Upon any payment or distribution referred to in this Article, the
Trustee and the Holders of the Debentures shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which a dissolution, winding up or total or partial liquidation or reorganization of the Company is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of the
Debentures, for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article. 
 SECTION 508. Trustee Not Fiduciary for
Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of
the Debentures or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. 

SECTION 509. Rights of Trustee as Holder of Senior Indebtedness. The Trustee in its individual capacity shall be entitled to all
the rights set forth in this Article with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Supplemental Indenture shall deprive the Trustee of
any of its rights as such holder. 
 SECTION 510. Article Applicable to Paying Agent. In case at any time any Paying
Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the context shall otherwise require) be construed as extending to and
including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that this Section shall not apply to the Company or
any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 

  
 15 









 SECTION 511. Rights of Holders of Senior Indebtedness Not Impaired. No right of any
present or future holder of Senior Indebtedness to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the
terms, provisions and covenants of the Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with.

 DTE ENERGY COMPANY 
 2011 Series I 6.50% Junior Subordinated Debentures due 2061 
 DTE ENERGY COMPANY, a
corporation duly organized and existing under the laws of the State of Michigan (herein referred to as the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby
promises to pay to CEDE & CO., or registered assigns, the principal sum of $             on December 1, 2061 (“Stated Maturity”), unless previously redeemed,
and to pay interest at the rate of 6.50% per annum on said principal sum from the date of issuance until the principal of this Debenture becomes due and payable, and on any overdue principal and (to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at the same rate per annum during such overdue period. Interest on this Debenture will be payable quarterly in arrears on March 1, June 1, September 1
and December 1 of each year (each such date, an “Interest Payment Date”), commencing March 1, 2012. 
 The amount of
interest payable for any period shall be computed on the basis of twelve 30-day months and a 360-day year and, for any period shorter than a full quarterly interest period, will be computed on the basis of the actual number of days elapsed per
30-day month. In the event that the Stated Maturity, any Redemption Date, or any date on which interest is payable on this Debenture is not a Business Day, then payment of the amount payable on such date will be made on the next succeeding day which
is a Business Day (and without any interest or other payment 

  
 A-1









 
in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day without reduction in
the amount due to such early payment, in each case with the same force and effect as if made on such date. Payments of interest may be deferred by the Company pursuant to the provisions of Article Two of the Supplemental Indenture (as defined
herein) to the Indenture (as defined herein). The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date with respect to this Debenture will, as provided in the Indenture, be paid to the person in
whose name this Debenture (or one or more Predecessor Securities) is registered at the close of business on the relevant Regular Record Date prior to the relevant Interest Payment Date. Any such interest installment not punctually paid or duly
provided for shall forthwith cease to be payable to the registered Holders on such Regular Record Date, and may either be paid to the person in whose name this Debenture (or one or more Predecessor Securities) is registered at the close of business
on a Special Record Date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the registered Holders of this series of Debentures not less than ten days prior to such Special Record Date, or may be
paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debentures may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the
Indenture. Except as otherwise provided in the Indenture, the principal of and the interest on this Debenture shall be payable at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in
any coin or currency of the United States of America which at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to
the registered Holder at the close of business on the Regular Record Date at such address as shall appear in the Security Register. Notwithstanding anything else contained herein, if this Debenture is a Global Debenture and is held in book-entry
form through the facilities of the Depositary, payments on this Debenture will be made to the Depositary or its nominee in accordance with arrangements then in effect between the Trustee and the Depositary. 

All references in this Debenture to interest shall include Compound Interest, if any. 
 This Debenture is one of a duly authorized series of Securities of the Company, designated as the “2011 Series I 6.50% Junior Subordinated Debentures due 2061” (the “Debentures”),
limited to an aggregate principal amount of $322,000,000 (except for Debentures authenticated and delivered upon transfer of, or in exchange for, or in lieu of other Debentures), all issued under and pursuant to an Amended and Restated Indenture,
dated as of April 9, 2001, as supplemented by the Supplemental Indenture dated as of December 1, 2011, with respect to the Debentures (the “Supplemental Indenture”), as further amended, supplemented or otherwise modified from
time to time (as so amended, supplemented or modified, the “Indenture”), duly executed and delivered between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein referred to as the “Trustee”, which
term includes any successor trustee under the Indenture), to which Indenture reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and
the registered Holders of the Debentures and of the terms upon which the Debentures are, and are to be, authenticated and delivered. 

  
 A-2









 Payment of the principal of and interest on this Debenture is, to the extent provided in the Indenture,
subordinated and subject in right of payment to the prior payment in full of all existing and future Senior Indebtedness of the Company and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each registered
Holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination so provided and (c) appoints the Trustee as his or her attorney-in-fact for any and all such purposes. Each registered Holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of
the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such Holder upon said provisions. 

The Company and, by its acceptance of this Debenture or a beneficial interest herein, the registered Holder of, and any Person that acquires a beneficial
interest in, this Debenture agree that for United States federal, state and local tax purposes it is intended that this Debenture constitute indebtedness, and the Holder of, and any Person that acquires a beneficial interest in, this Debenture
agrees to treat this Debenture as indebtedness for United States federal income tax purposes. 
 This Debenture is not subject to repayment at
the option of the Holder hereof. Except as provided below, this Debenture is not redeemable by the Company prior to maturity and is not subject to any sinking fund. 
 This Debenture shall be redeemable prior to its Stated Maturity at the option of the Company (i) in whole or in part, from time to time, on or after December 1, 2016 or (ii) at any time
prior to December 1, 2016, in whole but not in part, within 90 days following the occurrence and continuation of a Tax Event, in either case at a redemption price (the “Par Redemption Price”) equal to 100% of the principal amount
thereof, plus accrued and unpaid interest thereon (including Compound Interest, if any) to the Redemption Date. 
 This Debenture shall be
redeemable at the option of the Company prior to March 1, 2016, in whole or in part, on one or more occasions at any time following the occurrence and continuation of a Rating Agency Event, at a redemption price (the “Make-Whole Redemption
Price”) equal to the sum of the Make-Whole Amount, plus accrued and unpaid interest thereon (including Compound Interest, if any) to the Redemption Date. The Make-Whole Redemption Price for the Debentures will never be less than 100% of the
principal amount of the Debentures being redeemed plus accrued and unpaid interest on Debentures to the Redemption Date. 
 Notice of any
redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to the Holder hereof at its registered address. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest
will cease to accrue on the principal amount of this Debenture called for redemption. 
 If money sufficient to pay the Redemption Price with
respect to the principal amount of and accrued interest on the principal amount of this Debenture to be redeemed on the Redemption 

  
 A-3









 
Date is deposited with the Trustee on or before the Redemption Date and certain other conditions are satisfied, then on or after such date, interest will cease to accrue on the principal amount
of this Debenture called for redemption. 
 If the Debentures are only partially redeemed by the Company, the Debentures will be redeemed pro
rata or by lot or by any other method utilized by the Trustee; provided that if, at the time of redemption, the Debentures are registered as a Global Debenture, the Depositary shall determine by lot the principal amount of such Debentures held by
each Debenture Holder to be redeemed. 
 In the event of redemption of this Debenture in part only, a new Debenture or Debentures of this series
for the unredeemed portion hereof will be issued in the name of the registered Holder hereof upon the cancellation hereof. 
 In case an Event
of Default, as defined in the Supplemental Indenture, shall have occurred and be continuing, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture. 
 The provisions relating to defeasance and covenant defeasance in the Indenture in Section 403 thereof shall
not apply to this Debenture. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification
of the rights and obligations of the Company and the rights of the Holders of the Debentures under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority of the aggregate principal amount of all
Debentures issued under the Indenture at the time outstanding and affected thereby; provided, however, that no such amendment shall without the consent of the Holder of each Debenture so affected, among other things (i) change the stated
maturity of the principal of, or any installment of principal of or interest on any Debentures of any series, or reduce the principal amount thereof, or reduce the rate of interest thereon, or reduce any premium payable upon the redemption thereof,
(ii) reduce the aforesaid percentage of the Holders of which are required to consent to any such supplemental indenture or (iii) modify any of the subordination provisions contained herein in a manner adverse to the Holder hereof. The
Indenture also contains provisions permitting (i) the registered Holders of at least 66 2/3% in aggregate principal amount of the Securities of all series at the time outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) the registered Holders of not less than a majority in aggregate principal amount of the Securities of any series at the time
outstanding affected thereby, on behalf of the registered Holders of the Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the registered Holder of this Debenture
(unless revoked as provided in the Indenture) shall be conclusive and binding upon such registered Holder and upon all future registered Holders and owners of this Debenture and of any Debenture issued in exchange hereof or in place hereof (whether
by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Debenture. 

  
 A-4









 No reference herein to the Indenture and no provision of this Debenture or of the Indenture shall alter or
impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Debenture at the time and place and at the rate and in the coin or currency herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Debenture is registrable in the Security Register
of the Company, upon surrender of this Debenture for registration of transfer at the office or agency of the Company in any place where the principal of and any interest on this Debenture are payable or at such other offices or agencies as the
Company may designate, duly endorsed by or accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Security Registrar or any transfer agent duly executed by the registered Holder hereof or his or
her attorney duly authorized in writing, and thereupon one or more new Debentures of this series and of like tenor, of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees.
No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto. 
 Prior to due presentment for registration of transfer of this Debenture, the Company, the Trustee, any Paying Agent and any Security Registrar may deem and treat the registered Holder hereof as the
absolute owner hereof (whether or not this Debenture shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the
principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the contrary. 

The Debentures of this series are issuable only in fully registered form without coupons in denominations of $25 and any integral multiple thereof. This
Global Debenture is exchangeable for Debentures in definitive form only under certain limited circumstances set forth in the Indenture. Debentures of this series so issued are issuable only in registered form without coupons in denominations of $25
and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Debentures of this series are exchangeable for a like aggregate principal amount of Debentures of this series of a different
authorized denomination, as requested by the registered Holder surrendering the same. 
 As set forth in, and subject to the provisions of, the
Indenture, no registered owner of any Debenture will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless (i) such registered owner shall have previously given to the Trustee written
notice of a continuing Event of Default with respect to the Debentures of this series, (ii) the registered owners of not less than 25% in principal amount of the Outstanding Debentures of this series shall have made written request, and offered
reasonable indemnity, to the Trustee to institute such proceeding as trustee, (iii) the Trustee shall have failed to institute such proceeding within 60 days and (iv) the Trustee shall not have received from the registered owners of a
majority in principal amount of the outstanding Debentures of this series a direction inconsistent with such request within such 60-day period; provided, however, that such limitations do not apply to a suit instituted by the registered owner hereof
for the enforcement of payment of the principal of or any interest on this Debenture on or after the respective due dates expressed herein.

 Unless the Certificate of Authentication hereon has been executed by the Trustee or a duly appointed
Authentication Agent referred to herein, this Debenture shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 
 The Indenture and this Debenture shall be governed and construed in accordance with the laws of the State of New York. 
 All terms used in this Debenture which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
