Article III of the Indenture; and
		
	FURTHER ASSURANCE.	  	WHEREAS, the Original Indenture, by its terms, includes in the property subject to the lien thereof all of the estates and properties, real, personal and mixed, rights, privileges and franchises of every nature and kind and
wheresoever situate, then or thereafter owned or possessed by or belonging to the Company or to which it was then or at any time thereafter might be entitled in law or in equity (saving and excepting, however, the property therein specifically
excepted or released from the lien thereof), and the Company therein covenanted that it would, upon reasonable request, execute and deliver such further instruments as may be necessary or proper for the better assuring and confirming unto the

 PART I.

 
 CREATION OF THREE HUNDRED EIGHTY-FIFTH

SERIES OF BONDS,
 GENERAL AND
REFUNDING MORTGAGE BONDS,
 2022 SERIES A
  

		
	TERMS OF BONDS OF 2022 SERIES A.	  	SECTION 1. The Company hereby creates the three hundred eighty-fifth series of bonds to be issued under and secured by the Original Indenture as amended to date and as further amended by this Supplemental Indenture, to be
designated, and to be distinguished from the bonds of all other series, by the title “General and Refunding Mortgage Bonds, 2022 Series A” (elsewhere herein referred to as the “bonds of 2022 Series A”). The aggregate principal
amount of bonds of 2022 Series A shall be limited to five hundred million dollars ($500,000,000), except as provided in Sections 7 and 13 of Article II of the Original Indenture with respect to exchanges and replacements of bonds, and except further
that the Company may, without the consent of any holder of the bonds of 2022 Series A, “reopen” the bonds of 2022 Series A, so long as any additional bonds of 2022 Series A have the same tenor and terms as the bonds of 2022 Series A
established hereby.
		
		  	The bonds of 2022 Series A shall be issued as registered bonds without coupons in denominations of $2,000 and any larger amount that is an integral multiple of $1,000. The bonds of 2022 Series A shall be issued in the aggregate
principal amount of $500,000,000 shall mature on March 1, 2032 (subject to earlier redemption) and shall bear interest, payable semi-annually on March 1 and September 1 of each year (commencing September 1, 2022), at the rate of
three percent (3.00%) per annum until the principal thereof shall have become due and payable and thereafter until the Company’s obligation with respect to the payment of said principal shall have been discharged as provided in the Indenture.
The bonds of 2022 Series A will be issued in book-entry form through the facilities of The Depository Trust Company. Except as otherwise specifically provided in this Supplemental Indenture, the bonds of 2022 Series A shall be payable, as to
principal, premium, if any, and interest, at the office or agency of the Company in the Borough of Manhattan, the City and State of New York, in any coin or currency of the United States of America which at the time of payment is legal tender for
public and private debts.
		
		  	Except as provided herein, each bond of 2022 Series A shall be dated the date of its authentication and interest shall be payable on the principal represented thereby from the March 1 or September 1 next preceding the date
to which interest has been paid on bonds of 2022 Series A, unless the bond is authenticated on a date prior to September 1, 2022 in which case interest shall be payable from February 24, 2022.
		
		  	The bonds of 2022 Series A in definitive form shall be, at the election of the Company, fully engraved or shall be lithographed or printed in authorized denominations as aforesaid and numbered
R-1 and upwards (with such further designation as may be appropriate and desirable to indicate by such designation the form, series and denomination of bonds of 2022 Series A). Until bonds of 2022 Series A in
definitive form are ready for delivery, the Company may execute, and upon its request in writing the Trustee shall authenticate and deliver in lieu thereof, bonds of 2022 Series A in temporary form, as provided in Section 10 of Article II of
the Indenture. Temporary bonds of 2022 Series A if any, may be printed and may be issued in authorized denominations in substantially the form of definitive bonds of 2022 Series A, but without a recital of redemption prices and with such omissions,
insertions and variations as may be appropriate for temporary bonds, all as may be determined by the Company.


  
 12 









			
		
		  	Interest on any bond of 2022 Series A that is payable on any interest payment date and is punctually paid or duly provided for shall be paid to the person in whose name that bond, or any previous bond to the extent evidencing the
same debt as that evidenced by that bond, is registered at the close of business on the regular record date for such interest, which regular record date shall be the fifteenth calendar day (whether or not such day is a business day) immediately
preceding the applicable interest payment date. If the Company shall default in the payment of the interest due on any interest payment date on the principal represented by any bond of 2022 Series A, such defaulted interest shall forthwith cease to
be payable to the registered holder of that bond on the relevant regular record date by virtue of his having been such holder, and such defaulted interest may be paid to the registered holder of that bond (or any bond or bonds of 2022 Series A
issued upon transfer or exchange thereof) on the date of payment of such defaulted interest or, at the election of the Company, to the person in whose name that bond (or any bond or bonds of 2022 Series A issued upon transfer or exchange thereof) is
registered on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of bonds of 2022 Series A not less than ten (10) days preceding such subsequent record date, which subsequent record date
shall be at least five (5) days prior to the payment date of such defaulted interest. Interest will be computed on the basis of a 360-day year of twelve 30-day
months.
		
		  	Bonds of 2022 Series A, in definitive and temporary form, may bear such legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto.
		
		  	If any interest payment date, date of redemption or the stated maturity for the bonds of 2022 Series A would otherwise be a day that is not a business day, payment of principal and/or interest or premium, if any, with respect to the
bonds of 2022 Series A will be paid on the next succeeding business day with the same force and effect as if made on such date and no interest on such payment will accrue from and after such date
		
		  	“Business day” means any day other than a day on which banking institutions in the State of New York or the State of Michigan are authorized or obligated pursuant to law or executive order to close
		
	REDEMPTION OF BONDS OF 2022
SERIES A.	  	SECTION 2. Bonds of 2022 Series A will be redeemable at the option of the Company, in whole at any time or in part from time to time at the redemption prices set forth below.
		
		  	Prior to December 1, 2031 (the “Series A Par Call Date”), the Company may redeem the Bonds of 2022 Series A at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as
a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming
the Bonds of 2022 Series A matured on the Series A Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Rate plus 15 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Bonds of 2022 Series A to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption
date.


  
 13 









			
		
		  	On or after the Series A Par Call Date, the Company may redeem the Bonds of 2022 Series A, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Bonds of 2022
Series A being redeemed plus accrued and unpaid interest thereon to the redemption date.
		
		  	“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.
		
		  	The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on
the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve
System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any
successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable:
		
		  	 (1)   the yield for the Treasury constant maturity on H.15 exactly equal to the
period from the redemption date to the Series A Par Call Date (the “Remaining Life”); or

(2)   if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life,
the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall
interpolate to the Series A Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

(3)   if there is no such Treasury constant maturity on H.15 shorter than or longer than the
Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal
to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

		
		  	If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the
semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Series A Par Call
Date, as applicable. If there is no United States Treasury security maturing on the Series A Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Series A Par Call Date, one with a
maturity date preceding the Series A Par Call Date and one with a maturity date following the Series A Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Series A Par Call Date. If there
are two or more United States Treasury securities maturing on the Series A Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United
States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury


  
 14 









			
		
		  	securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based
upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.
		
		  	The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.
		
		  	The bonds of 2022 Series A shall be redeemable as aforesaid upon giving notice of such redemption by first class mail, postage prepaid, by or on behalf of the Company at least thirty (30) days, but not more than sixty
(60) days, prior to the date fixed for redemption to the registered holders of bonds of 2022 Series A so called for redemption at their last respective addresses appearing on the register thereof, but failure to mail such notice to the
registered holders of any bonds of 2022 Series A designated for redemption shall not affect the validity of any such redemption of any other bonds of such series. Interest shall cease to accrue on any bonds of 2022 Series A (or any portion thereof)
so called for redemption from and after the date fixed for redemption if payment sufficient to redeem the bonds of 2022 Series A (or such portion) designated for redemption has been duly provided for. Bonds of 2022 Series A redeemed in part only
shall be in amounts of $2,000 or any larger amount that is an integral multiple of $1,000.
		
		  	If the giving of the notice of redemption shall have been completed, or if provision satisfactory to the Trustee for the giving of such notice shall have been made, and if the Company shall have deposited with the Trustee in
trust funds (which shall have become available for payment to the holders of the bonds of 2022 Series A so to be redeemed) sufficient to redeem bonds of 2022 Series A in whole or in part, on the date fixed for redemption, then all obligations of the
Company in respect of such bonds (or portions thereof) so to be redeemed and interest due or to become due thereon shall cease and be discharged and the holders of such bonds of 2022 Series A (or portions thereof) shall thereafter be restricted
exclusively to such funds for any and all claims of whatsoever nature on their part under the Indenture or in respect of such bonds (or portions thereof) and interest.
		
		  	The bonds of 2022 Series A shall not be entitled to or subject to any sinking fund and shall not be redeemable other than as provided in Section 2 hereof.
		
	EXCHANGE AND TRANSFER.	  	SECTION 3. At the option of the registered holder, any bonds of 2022 Series A, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, the City and State of New York, together with
a written instrument of transfer (if so required by the Company or by the Trustee) in form approved by the Company duly executed by the holder or by its duly authorized attorney, shall be exchangeable for a like aggregate principal amount of bonds
of 2022 Series A upon the terms and conditions specified herein and in Section 7 of Article II of the Indenture. The Company waives its rights under Section 7 of Article II of the Indenture not to make exchanges or transfers of bonds of
2022 Series A during any period of ten (10) days next preceding any redemption date for such bonds.
		
		  	Bonds of 2022 Series A, in definitive and temporary form, may bear such legends as may be necessary to comply with any law or with any rules or regulations made pursuant
thereto.

		  	DTE ELECTRIC COMPANY (hereinafter called the “Company”), a corporation of the State of Michigan, for value received, hereby promises to pay to [Cede & Co.], or registered assigns, at the Company’s office or
agency in the Borough of Manhattan, the City and State of New York, the principal sum of _________________ dollars ($_______) in lawful money of the United States of America on March 1, 2032 (subject to earlier redemption) and interest thereon
at the rate of 3.00% per annum, in like lawful money, from February 24, 2022 and after the first payment of interest on bonds of this Series has been made or otherwise provided for, from the most recent date to which interest has been paid or
otherwise provided for, semi-annually on March 1 and September 1 of each year (commencing September 1, 2022), until the Company’s obligation with respect to payment of said principal shall have been discharged, all as provided,
to the extent and in the manner specified in the Indenture hereinafter mentioned and in the supplemental indenture pursuant to which this bond has been issued.
		
		  	This bond is one of an authorized issue of bonds of the Company, unlimited as to amount except as provided in the Indenture hereinafter mentioned or any indentures supplemental thereto, and is one of a series of General and
Refunding Mortgage Bonds known as 2022 Series A, limited to an aggregate principal amount of $500,000,000, except as otherwise provided in the Indenture hereinafter mentioned. This bond and all other bonds of said series are issued and to be issued
under, and are all equally and ratably secured (except insofar as any sinking, amortization, improvement or analogous fund, established in accordance with the provisions of the Indenture hereinafter mentioned, may afford additional security for the
bonds of any particular series and except as provided in Section 3 of Article VI of said Indenture) by an Indenture, dated as of October 1, 1924, duly

		  	executed by the Company to The Bank of New York Mellon Trust Company, N.A., as successor Trustee, to which Indenture and all indentures supplemental thereto (including the Supplemental Indenture dated as of February 1, 2022)
reference is hereby made for a description of the properties and franchises mortgaged and conveyed, the nature and extent of the security, the terms and conditions upon which the bonds are issued and under which additional bonds may be issued, and
the rights of the holders of the bonds and of the Trustee in respect of such security (which Indenture and all indentures supplemental thereto, including the Supplemental Indenture dated as of February 1, 2022, are hereinafter collectively
called the “Indenture”). As provided in the Indenture, said bonds may be for various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as in said
Indenture provided. With the consent of the Company and to the extent permitted by and as provided in the Indenture, the rights and obligations of the Company and of the holders of the bonds and the terms and provisions of the Indenture, or of any
indenture supplemental thereto, may be modified or altered in certain respects by affirmative vote of at least eighty-five percent (85%) in amount of the bonds then outstanding, and, if the rights of one or more, but less than all, series of bonds
then outstanding are to be affected by the action proposed to be taken, then also by affirmative vote of at least eighty-five percent (85%) in amount of the series of bonds so to be affected (excluding in every instance bonds disqualified from
voting by reason of the Company’s interest therein as specified in the Indenture); provided, however, that, without the consent of the holder hereof, no such modification or alteration shall, among other things, affect the terms of payment of
the principal of or the interest on this bond, which in those respects is unconditional.
		
		  	This bond is not subject to repayment at the option of the holder hereof. Except as provided below, this bond is not redeemable by the Company prior to maturity and is not subject to any sinking fund.
		
		  	Prior to December 1 , 2031 (the “Series A Par Call Date”), the Company may redeem this bond at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of
principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest hereon discounted to the redemption date (assuming this bond matured
on the Series A Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less
(b) interest accrued to the date of redemption, and (2) 100% of the principal amount of this bond to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption date.
		
		  	On or after the Series A Par Call Date, the Company may redeem this bond, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of this bond being redeemed plus accrued
and unpaid interest thereon to the redemption date.
		
		  	“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.
		
		  	The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the
third


  
 17 









			
		
		  	business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal
Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal”
(or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable:
		
		  	 (1)   the yield for the Treasury constant maturity on H.15 exactly equal to the
period from the redemption date to the Series A Par Call Date (the “Remaining Life”); or

(2)   if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life,
the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall
interpolate to the Series A Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

(3)   if there is no such Treasury constant maturity on H.15 shorter than or longer than the
Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal
to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

		
		  	If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual
equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Series A Par Call Date, as
applicable. If there is no United States Treasury security maturing on the Series A Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Series A Par Call Date, one with a maturity
date preceding the Series A Par Call Date and one with a maturity date following the Series A Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Series A Par Call Date. If there are two or
more United States Treasury securities maturing on the Series A Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States
Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate
in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00
a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.
		
		  	The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.


  
 18 









			
		
		  	Notice of any optional redemption will be mailed at least 30 days but not more than 60 days before the optional redemption date to the holder hereof at its registered address. If notice has been provided in accordance with the
Indenture and funds for the redemption of this bond called for redemption have been made available on the redemption date, this bond will cease to bear interest on the date fixed for redemption. Thereafter, the only right of the holder hereof will
be to receive payment of the redemption price.
		
		  	Under the Indenture, funds may be deposited with the Trustee (which shall have become available for payment), in advance of the redemption date of any of the bonds of this series (or portions thereof), in trust for the redemption of
such bonds (or portions thereof) and the interest due or to become due thereon, and thereupon all obligations of the Company in respect of such bonds (or portions thereof) so to be redeemed and such interest shall cease and be discharged, and the
holders thereof shall thereafter be restricted exclusively to such funds for any and all claims of whatsoever nature on their part under the Indenture or with respect to such bonds (or portions thereof) and interest.
		
		  	In case an event of default, as defined in the Indenture, shall occur, the principal of all the bonds issued thereunder may become or be declared due and payable, in the manner, with the effect and subject to the conditions provided
in the Indenture.
		
		  	The bonds of this series are issuable only in fully registered form without coupons in denominations of $2,000 and any larger amount that is an integral multiple of $1,000. This Global Security is exchangeable for bonds in
definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, bonds of this series are exchangeable for a like aggregate principal amount of
bonds of this series of a different authorized denomination, as requested by the registered holder surrendering the same.
		
		  	This bond is transferable by the registered holder hereof, in person or by his attorney duly authorized in writing, on the books of the Company kept at its office or agency in the Borough of Manhattan, the City and State of New
York, upon surrender and cancellation of this bond, and thereupon, a new registered bond of the same series of authorized denominations for a like aggregate principal amount will be issued to the transferee in exchange therefor, and this bond with
others in like form may in like manner be exchanged for one or more new bonds of the same series of other authorized denominations, but of the same aggregate principal amount, all as provided and upon the terms and conditions set forth in the
Indenture, and upon payment, in any event, of the charges prescribed in the Indenture.
		
		  	No recourse shall be had for the payment of the principal of or the interest on this bond, or for any claim based hereon or otherwise in respect hereof or of the Indenture, or of any indenture supplemental thereto, against any
incorporator, or against any past, present or future stockholder, director or officer, as such, of the Company, or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation,
whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise howsoever; all such liability being, by the acceptance hereof and as part of
the consideration for the issue hereof, expressly waived and released by every holder or owner hereof, as more fully provided in the Indenture.

		  	This bond shall not be valid or become obligatory for any purpose until The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, or its successor thereunder, shall have signed the form of certificate
endorsed hereon.
		
		  	IN WITNESS WHEREOF, DTE ELECTRIC COMPANY has caused this instrument to be executed by an authorized officer, with his or her manual or facsimile signatures, and its corporate seal, or a facsimile thereof, to be impressed or

		  	PART II.
		
		  	CREATION OF THREE HUNDRED EIGHTY-SIXTH
		  	SERIES OF BONDS,
		  	GENERAL AND REFUNDING MORTGAGE BONDS,
		  	2022 GREEN SERIES B

  

			
		
	TERMS OF BONDS OF 2022 GREEN SERIES B.	  	SECTION 1. The Company hereby creates the three hundred eighty-sixth series of bonds to be issued under and secured by the Original Indenture as amended to date and as further amended by this Supplemental Indenture, to be
designated, and to be distinguished from the bonds of all other series, by the title “General and Refunding Mortgage Bonds, 2022 Green Series B” (elsewhere herein referred to as the “bonds of 2022 Series B”). The aggregate
principal amount of bonds of 2022 Series B shall be limited to four hundred million dollars ($400,000,000), except as provided in Sections 7 and 13 of Article II of the Original Indenture with respect to exchanges and replacements of bonds, and
except further that the Company may, without the consent of any holder of the bonds of 2022 Series B, “reopen” the bonds of 2022 Series B, so long as any additional bonds of 2022 Series B have the same tenor and terms as the bonds of 2022
Series B established hereby.
		
		  	The bonds of 2022 Series B shall be issued as registered bonds without coupons in denominations of $2,000 and any larger amount that is an integral multiple of $1,000. The bonds of 2022 Series B shall be issued in the aggregate
principal amount of $400,000,000, shall mature on March 1, 2052 (subject to earlier redemption) and shall bear interest, payable semi-annually on March 1 and September 1 of each year (commencing September 1, 2022, at the rate of
three and sixty-five hundredths percent (3.65%) per annum until the principal thereof shall have become due and payable and thereafter until the Company’s obligation with respect to the payment of said principal shall have been discharged as
provided in the Indenture. The bonds of 2022 Series B will be issued in book-entry form through the facilities of The Depository Trust Company. Except as otherwise specifically provided in this Supplemental Indenture, the bonds of 2022 Series B
shall be payable, as to principal, premium, if any, and interest, at the office or agency of the Company in the Borough of Manhattan, the City and State of New York, in any coin or currency of the United States of America which at the time of
payment is legal tender for public and private debts.
		
		  	Except as provided herein, each bond of 2022 Series B shall be dated the date of its authentication and interest shall be payable on the principal represented thereby from the March 1 or September 1 next preceding the date
to which interest has been paid on bonds of 2022 Series B, unless the bond is authenticated on a date prior to September 1, 2022 in which case interest shall be payable from February 24, 2022.
		
		  	The bonds of 2022 Series B in definitive form shall be, at the election of the Company, fully engraved or shall be lithographed or printed in authorized denominations as aforesaid and numbered
R-1 and upwards (with such further designation as may be appropriate and desirable to indicate by such designation the form, series and denomination of bonds of 2022 Series B). Until bonds of 2022 Series B in
definitive form are ready for delivery, the Company may execute, and upon its request in writing the Trustee shall authenticate and deliver in lieu thereof, bonds of 2022 Series B in temporary form, as provided in Section 10 of Article II of
the Indenture. Temporary bonds of 2022 Series B if any, may be printed and may be issued in authorized denominations in substantially the form of definitive bonds of 2022 Series B, but without a recital of redemption prices and with such omissions,
insertions and variations as may be appropriate for temporary bonds, all as may be determined by the Company.


  
 21 









			
		
		  	Interest on any bond of 2022 Series B that is payable on any interest payment date and is punctually paid or duly provided for shall be paid to the person in whose name that bond, or any previous bond to the extent evidencing the
same debt as that evidenced by that bond, is registered at the close of business on the regular record date for such interest, which regular record date shall be the fifteenth calendar day (whether or not such day is a business day) immediately
preceding the applicable interest payment date. If the Company shall default in the payment of the interest due on any interest payment date on the principal represented by any bond of 2022 Series B, such defaulted interest shall forthwith cease to
be payable to the registered holder of that bond on the relevant regular record date by virtue of his having been such holder, and such defaulted interest may be paid to the registered holder of that bond (or any bond or bonds of 2022 Series B
issued upon transfer or exchange thereof) on the date of payment of such defaulted interest or, at the election of the Company, to the person in whose name that bond (or any bond or bonds of 2022 Series B issued upon transfer or exchange thereof) is
registered on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of bonds of 2022 Series B not less than ten (10) days preceding such subsequent record date, which subsequent record date
shall be at least five (5) days prior to the payment date of such defaulted interest. Interest will be computed on the basis of a 360-day year of twelve 30-day
months.
		
		  	Bonds of 2022 Series B, in definitive and temporary form, may bear such legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto.
		
		  	If any interest payment date, date of redemption or the stated maturity for the bonds of 2022 Series B would otherwise be a day that is not a business day, payment of principal and/or interest or premium, if any, with respect to the
bonds of 2022 Series B will be paid on the next succeeding business day with the same force and effect as if made on such date and no interest on such payment will accrue from and after such date
		
		  	“Business day” means any day other than a day on which banking institutions in the State of New York or the State of Michigan are authorized or obligated pursuant to law or executive order to close
		
	REDEMPTION OF BONDS OF 2022 GREEN SERIES B.	  	SECTION 2. Bonds of 2022 Series B will be redeemable at the option of the Company, in whole at any time or in part from time to time at the redemption prices set forth below.
		
		  	Prior to September 1, 2051 (the “Series B Par Call Date”), the Company may redeem the Bonds of 2022 Series B at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a
percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the
Bonds of 2022 Series B matured on the Series B Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate
plus 20 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Bonds of 2022 Series B to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption
date.
		
		  	On or after the Series B Par Call Date, the Company may redeem the Bonds of 2022 Series B, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Bonds of 2022
Series B being redeemed plus accrued and unpaid interest thereon to the redemption date.


  
 22 









			
		  	“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.
		
		  	 The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government
securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most
recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption
“U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable:

(1)   the yield for the Treasury constant maturity on H.15 exactly equal to the period from the
redemption date to the Series B Par Call Date (the “Remaining Life”); or
 (2)   if
there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury
constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Series B Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal
places; or
 (3)   if there is no such Treasury constant maturity on H.15 shorter than or longer
than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity
date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

		
		  	If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual
equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Series B Par Call Date, as
applicable. If there is no United States Treasury security maturing on the Series B Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Series B Par Call Date, one with a maturity
date preceding the Series B Par Call Date and one with a maturity date following the Series B Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Series B Par Call Date. If there are two or
more United States Treasury securities maturing on the Series B Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States
Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate
in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00
a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.


  
 23 









			
		  	The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.
		
		  	The bonds of 2022 Series B shall be redeemable as aforesaid upon giving notice of such redemption by first class mail, postage prepaid, by or on behalf of the Company at least thirty (30) days, but not more than sixty
(60) days, prior to the date fixed for redemption to the registered holders of bonds of 2022 Series B so called for redemption at their last respective addresses appearing on the register thereof, but failure to mail such notice to the
registered holders of any bonds of 2022 Series B designated for redemption shall not affect the validity of any such redemption of any other bonds of such series. Interest shall cease to accrue on any bonds of 2022 Series B (or any portion thereof)
so called for redemption from and after the date fixed for redemption if payment sufficient to redeem the bonds of 2022 Series B (or such portion) designated for redemption has been duly provided for. Bonds of 2022 Series B redeemed in part only
shall be in amounts of $2,000 or any larger amount that is an integral multiple of $1,000.
		
		  	If the giving of the notice of redemption shall have been completed, or if provision satisfactory to the Trustee for the giving of such notice shall have been made, and if the Company shall have deposited with the Trustee in trust
funds (which shall have become available for payment to the holders of the bonds of 2022 Series B so to be redeemed) sufficient to redeem bonds of 2022 Series B in whole or in part, on the date fixed for redemption, then all obligations of the
Company in respect of such bonds (or portions thereof) so to be redeemed and interest due or to become due thereon shall cease and be discharged and the holders of such bonds of 2022 Series B (or portions thereof) shall thereafter be restricted
exclusively to such funds for any and all claims of whatsoever nature on their part under the Indenture or in respect of such bonds (or portions thereof) and interest.
		
		  	The bonds of 2022 Series B shall not be entitled to or subject to any sinking fund and shall not be redeemable other than as provided in Section 2 hereof.
		
	EXCHANGE AND TRANSFER.	  	SECTION 3. At the option of the registered holder, any bonds of 2022 Series B, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, the City and State of New York, together with
a written instrument of transfer (if so required by the Company or by the Trustee) in form approved by the Company duly executed by the holder or by its duly authorized attorney, shall be exchangeable for a like aggregate principal amount of bonds
of 2022 Series B upon the terms and conditions specified herein and in Section 7 of Article II of the Indenture. The Company waives its rights under Section 7 of Article II of the Indenture not to make exchanges or transfers of bonds of
2022 Series B during any period of ten (10) days next preceding any redemption date for such bonds.
		
		  	Bonds of 2022 Series B, in definitive and temporary form, may bear such legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto.

otherwise provided for, semi-annually on March 1 and September 1 of each year (commencing September 1, 2022), until the Company’s obligation with respect to payment of said principal shall have been discharged, all as provided,
to the extent and in the manner specified in the Indenture hereinafter mentioned and in the supplemental indenture pursuant to which this bond has been issued.


  
 25 









			
		  	This bond is one of an authorized issue of bonds of the Company, unlimited as to amount except as provided in the Indenture hereinafter mentioned or any indentures supplemental thereto, and is one of a series of General and
Refunding Mortgage Bonds known as 2022 Green Series B, limited to an aggregate principal amount of $400,000,000, except as otherwise provided in the Indenture hereinafter mentioned. This bond and all other bonds of said series are issued and to be
issued under, and are all equally and ratably secured (except insofar as any sinking, amortization, improvement or analogous fund, established in accordance with the provisions of the Indenture hereinafter mentioned, may afford additional security
for the bonds of any particular series and except as provided in Section 3 of Article VI of said Indenture) by an Indenture, dated as of October 1, 1924, duly executed by the Company to The Bank of New York Mellon Trust Company, N.A., as
successor Trustee, to which Indenture and all indentures supplemental thereto (including the Supplemental Indenture dated as of February 1, 2022) reference is hereby made for a description of the properties and franchises mortgaged and
conveyed, the nature and extent of the security, the terms and conditions upon which the bonds are issued and under which additional bonds may be issued, and the rights of the holders of the bonds and of the Trustee in respect of such security
(which Indenture and all indentures supplemental thereto, including the Supplemental Indenture dated as of February 1, 2022, are hereinafter collectively called the “Indenture”). As provided in the Indenture, said bonds may be for
various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as in said Indenture provided. With the consent of the Company and to the extent permitted by and as
provided in the Indenture, the rights and obligations of the Company and of the holders of the bonds and the terms and provisions of the Indenture, or of any indenture supplemental thereto, may be modified or altered in certain respects by
affirmative vote of at least eighty-five percent (85%) in amount of the bonds then outstanding, and, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected by the action proposed to be taken, then also
by affirmative vote of at least eighty-five percent (85%) in amount of the series of bonds so to be affected (excluding in every instance bonds disqualified from voting by reason of the Company’s interest therein as specified in the Indenture);
provided, however, that, without the consent of the holder hereof, no such modification or alteration shall, among other things, affect the terms of payment of the principal of or the interest on this bond, which in those respects is
unconditional.
		
		  	This bond is not subject to repayment at the option of the holder hereof. Except as provided below, this bond is not redeemable by the Company prior to maturity and is not subject to any sinking fund.
		
		  	Prior to September 1, 2051 (the “Series B Par Call Date”), the Company may redeem this bond at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of
principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest hereon discounted to the redemption date (assuming this bond matured
on the Series B Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points less
(b) interest accrued to the date of redemption, and (2) 100% of the principal amount of this bond to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption date.
		
		  	On or after the Series B Par Call Date, the Company may redeem this bond, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of this bond being redeemed plus accrued
and unpaid interest thereon to the redemption date.
		
		  	“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.


  
 26 









			
		  	 The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government
securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most
recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption
“U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable:

 
 (1)   the yield for the
Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Series B Par Call Date (the “Remaining Life”); or
  

(2)   if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life,
the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall
interpolate to the Series B Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or
  

(3)   if there is no such Treasury constant maturity on H.15 shorter than or longer than the
Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal
to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

		
		  	If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual
equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Series B Par Call Date, as
applicable. If there is no United States Treasury security maturing on the Series B Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Series B Par Call Date, one with a maturity
date preceding the Series B Par Call Date and one with a maturity date following the Series B Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Series B Par Call Date. If there are two or
more United States Treasury securities maturing on the Series B Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States
Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate
in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00
a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.
		
		  	The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.
		
		  	Notice of any optional redemption will be mailed at least 30 days but not more than 60 days before the optional redemption date to the holder hereof at its registered address. If notice has been provided in accordance with the
Indenture and funds for the redemption of this bond called for redemption have been made available on the redemption date, this bond will cease to bear interest on the date fixed for redemption. Thereafter, the only right of the holder hereof will
be to receive payment of the redemption price.


  
 27 









			
		  	Under the Indenture, funds may be deposited with the Trustee (which shall have become available for payment), in advance of the redemption date of any of the bonds of this series (or portions thereof), in trust for the redemption of
such bonds (or portions thereof) and the interest due or to become due thereon, and thereupon all obligations of the Company in respect of such bonds (or portions thereof) so to be redeemed and such interest shall cease and be discharged, and the
holders thereof shall thereafter be restricted exclusively to such funds for any and all claims of whatsoever nature on their part under the Indenture or with respect to such bonds (or portions thereof) and interest.
		
		  	In case an event of default, as defined in the Indenture, shall occur, the principal of all the bonds issued thereunder may become or be declared due and payable, in the manner, with the effect and subject to the conditions provided
in the Indenture.
		
		  	The bonds of this series are issuable only in fully registered form without coupons in denominations of $2,000 and any larger amount that is an integral multiple of $1,000. This Global Security is exchangeable for bonds in
definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, bonds of this series are exchangeable for a like aggregate principal amount of
bonds of this series of a different authorized denomination, as requested by the registered holder surrendering the same.
		
		  	This bond is transferable by the registered holder hereof, in person or by his attorney duly authorized in writing, on the books of the Company kept at its office or agency in the Borough of Manhattan, the City and State of New
York, upon surrender and cancellation of this bond, and thereupon, a new registered bond of the same series of authorized denominations for a like aggregate principal amount will be issued to the transferee in exchange therefor, and this bond with
others in like form may in like manner be exchanged for one or more new bonds of the same series of other authorized denominations, but of the same aggregate principal amount, all as provided and upon the terms and conditions set forth in the
Indenture, and upon payment, in any event, of the charges prescribed in the Indenture.
		
		  	No recourse shall be had for the payment of the principal of or the interest on this bond, or for any claim based hereon or otherwise in respect hereof or of the Indenture, or of any indenture supplemental thereto, against any
incorporator, or against any past, present or future stockholder, director or officer, as such, of the Company, or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation,
whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise howsoever; all such liability being, by the acceptance hereof and as part of
the consideration for the issue hereof, expressly waived and released by every holder or owner hereof, as more fully provided in the Indenture.
		
		  	This bond shall not be valid or become obligatory for any purpose until The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, or its successor thereunder, shall have signed the form of certificate
endorsed hereon.
		
		  	IN WITNESS WHEREOF, DTE ELECTRIC COMPANY has caused this instrument to be executed by an authorized officer, with his or her manual or facsimile signatures, and its corporate seal, or a facsimile thereof, to be impressed or
imprinted hereon and the same to be attested by its Corporate Secretary or Assistant Corporate Secretary by manual or facsimile signature.
