                                             [FORM OF REVERSE OF BOND]
 
                  
                       This bond is the only bond 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 said bonds known as General and Refunding Mortgage Bonds,
                     1990 Series A (elsewhere herein referred to as the "1990 Series A Bond"),
                     limited to an aggregate principal amount of $194,649,000, except as
                     otherwise provided in the Indenture hereinafter mentioned. This bond is
                     issued and to be issued under, and is 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 Bankers Trust Company, a corporation of the State of New
                     York, as Trustee, to which Indenture and all indentures supplemental
                     thereto (including the Supplemental Indenture dated as of February 15,
                     1990) 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 15, 1990, 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 principal 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 principal 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.
 
                       The holder of the 1990 Series A Bond, by its acceptance of and holding
                     thereof, consents and agrees that bonds of any series may be issued which
                     mature on a date or dates later than October 1, 2024 and also consents to
                     the deletion from the first paragraph of Section 5 of Article II of the
                     Indenture of the phrase "but in no event later than October 1, 2024." Such
                     holder further agrees that (a) such consent shall, for all purposes of
                     Article XV of the Indenture and without further action on the part of such
                     holder, be deemed the affirmative vote of such holder at any meeting
                     called pursuant to said Article XV for the purpose of approving such
                     deletion, and (b) such deletion shall become effective at such time as not
                     less than eighty-five percent (85%) in principal amount of bonds
                     outstanding under the Indenture shall have consented thereto substan-
                     tially in the manner set forth in Section 3 of Part I of the Supplemental
                     Indenture dated as of February 15, 1990, or in writing, or by affirmative
                     vote cast at a meeting called pursuant to said Article XV, or by any
                     combination thereof.
 
                       Principal payments shall be made hereon annually, payable on March 31 of
                     each year (commencing March 31, 1990) as set forth below, until the final
                     payment of principal shall be made:

                       This bond shall be redeemable prior to stated maturity, at the election
                     of the Company on any interest payment date, at redemption prices
                     calculated in accordance with the formula set forth below on giving notice
                     of such redemption by first class mail, postage prepaid, by or on behalf
                     of the Company not more than ninety (90) days nor less than thirty (30)
                     days prior to the date fixed for redemption to the registered holder of
                     the 1990 Series A Bond.
 
                       Any such redemption payment shall be equal to one hundred percent (100%)
                     of the principal so redeemed, plus a prepayment premium, if any, in an
                     amount equal to one hundred percent (100%) of the amount of interest for
                     one year on the unpaid principal balance proposed to be redeemed,
                     multiplied by the ratio which the number of semi-annual payment dates
                     between the proposed redemption date and the final maturity date of the
                     series bears to the number of semi-annual payment dates between December
                     31, 1994 and the final maturity date, plus in each case accrued interest
                     to the date fixed for redemption. Any partial redemption shall, as the
                     principal portion of such redemption, be no less than $100,000. No

OF 1990 SERIES D.    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, 1990 Series D"
                     (elsewhere herein referred to as the "bonds of 1990 Series D"). The
                     aggregate principal amount of bonds of 1990 Series D shall be limited to
                     the principal amount of 1990 Series A Bond being exchanged, except as
                     provided in Sections 7 and 13 of Article II of the Original Indenture with
                     respect to exchanges and replacements of bonds.
 
                       The bonds of 1990 Series D shall mature on March 31, 2020 and shall be
                     issued in exchange for, and in an aggregate principal amount equal to the
                     principal amount remaining outstanding on, the 1990 Series A Bond as of
                     the date of such exchange. The Bonds of Series D shall be issued as
                     registered bonds without coupons in denominations of $10,000 and any
                     multiple thereof, and shall bear interest, payable semi-annually on March
                     31 and September 30 of each year (commencing on the first March 31 or
                     September 30 following the date of such exchange), at the rate of seven
                     and 904/1000 per centum (7.904%) per annum until the principal 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. Except as otherwise specifically provided in
                     this Supplemental Indenture, the principal of and interest on the bonds of
                     1990 Series D shall be payable at the office or agency of the Company in
                     the Borough of Manhattan, The City of New York, The 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. The interest on
                     bonds of 1990 Series D, whether in temporary or definitive form, shall be
                     payable without presentation of such bonds and (subject to the provisions
                     of this Section 1) only to or upon the written order of the registered
                     holders thereof.
 
                       Each bond of 1990 Series D shall be dated the date of its authentication
                     and interest shall be payable on the principal represented thereby from
                     the March 31 or September 30 next preceding the date thereof to which
                     interest has been paid on bonds of 1990 Series D, unless the bond is
                     authenticated on a date to which interest has been paid, in which case
                     interest shall be payable from the date of authentication.
 
                       The bonds of 1990 Series D 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 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 1990
                     Series D). Until bonds of 1990 Series D 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 1990
                     Series D in temporary form, as provided in Section 10 of Article II of the
                     Indenture. Temporary bonds of 1990 Series D, if any, may be printed and
                     may be issued in authorized denominations in substantially the form of
                     definitive bonds of 1990 Series D, 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.

                       Interest on any bond of 1990 Series D which 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 day of March or September as
                     the case may be (whether or not a business day) next preceding such
                     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 1990 Series D, 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 1990 Series D 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 1990 Series D 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 1990 Series
                     D 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.

                     shall have been made, and if the Company shall have deposited with the
                     Trustee in trust funds (which shall become available for payment to the

                     their part under the Indenture or in respect of such bonds (or portions
                     thereof) and interest.

                     D redeemed at the election of the Company otherwise than through the
                     sinking fund, in each case in satisfaction of all or any part of the
                     amount of any sinking fund payment. Each such bond of 1990 Series D shall
                     be received or credited for such purpose by the Trustee at the principal
                     amount thereof and the amount of such sinking fund payment shall be

                     the amount of the next ensuing sinking fund payment and the portions
                     thereof which are to be satisfied by payment of cash, by delivery of bonds
                     of 1990 Series D or by crediting bonds of 1990 Series D previously
                     redeemed. The treasurer's certificate shall also state that bonds of 1990
                     Series D forming the basis of any such credit do not include any bonds of
                     1990 Series D which have been called for redemption for the sinking fund
                     or previously credited against any sinking fund payment. The Trustee
                     shall, upon the receipt of the treasurer's certificate, select the bonds
                     of 1990 Series D to be redeemed upon the next ensuing March 31 in the

                     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,

                     fifteen (15) days prior to the date such payment shall become due and
                     payable.
 
                       When a semi-annual interest payment date falls on a Saturday, Sunday or
                     a day on which the Federal Reserve Bank of New York or the Trustee is not
                     open for business, all payments shall be payable on the first day
                     thereafter on which the Federal Reserve Bank of New York and the Trustee

                       In the event any semi-annual payment is not made when due, the amount
                     payable shall be such payment, plus interest thereon at the interest rate

REDEMPTION OF          SECTION 2. The 1990 Series B Bond shall be redeemable prior to stated
1990 SERIES B BOND.  maturity, at the election of the Company on any interest payment date, at
                     redemption prices calculated in accordance with the formula set forth
                     below on giving notice of such redemption by first class mail, postage
                     prepaid, by or on behalf of the Company not more than ninety (90) days nor
                     less than thirty (30) days prior to the date fixed for redemption to the
                     registered holder of the 1990 Series B Bond.
 
                       The optional redemption payment of each bond to be redeemed shall be
                     equal to the present worth, on the date of redemption, of the remaining
                     scheduled semi-annual payments of interest and annual retirement of
                     principal of such bond, calculated as follows. Determine the present value
                     of each scheduled semi-annual payment of interest and annual retirement of
                     principal by dividing each payment by the Present Value Divisor (PVD),
                     where:

                        I = That annual interest rate (which has been adjusted for semi-annual
                            compounding) for U.S. Treasury securities, with comparable maturities as
                            set forth in the Federal Reserve statistical release, designated
                            H.15 (519), or its successor, published at least 4 days but not
                            more than 10 days prior to the optional redemption date. The rate
                            shall be the "This Week" rate for Treasury Constant Maturities.

                            prepayment period to the nearest month (1st-15th round down) to
                            match the remaining term of the bond to be redeemed.
 
                       D =  Present value divisor for the preceding 6 month interest period (D
                            equals 1.0 for the period preceding the first period, which is the period
                            from the redemption date to the first scheduled payment date
                            thereafter).
 
                            Add the present value for all scheduled annual retirements of
                            principal and semi-annual payments of interest to determine the sum
                            to be paid upon redemption of each bond.
 
                            If the optional redemption payment is greater than the principal
                            outstanding as of the date of optional redemption, the prepayment
                            results in a premium, plus in each case accrued interest to the date
                            fixed for redemption. If the optional redemption payment is less
                            than the principal outstanding as of the date of the optional
                            redemption, the prepayment results in a discount which shall be
                            deducted from the outstanding principal amount which otherwise would
                            have been paid, plus in each case accrued interest to the date fixed
                            for redemption.

                     principal sum remaining unpaid from time to time from January 3, 1990, and
                     after the first interest payment hereon from the most recent date to which
                     interest has been paid hereon, 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 on the reverse hereof and in the supplemental indenture pursuant
                     to which this bond has been issued. Interest shall be due and payable in

                     supplemental indenture pursuant to which this bond has been issued.

                       When any payment date falls on a Saturday, Sunday or a day on which the
                     Federal Reserve Bank of New York or the Trustee is not open for business,
                     all payments shall be payable on the first day thereafter on which the

                     forty-five (45) days in advance of an interest payment date, this bond
                     shall be exchangeable, in whole but not in part, on any interest payment

                     principal which shall remain outstanding on this bond as of the date of
                     such exchange (after giving effect to the payment of principal hereon on
                     the date of such exchange), all as provided, to the extent and in the
                     manner specified in the Indenture and the Supplemental Indenture
                     hereinafter mentioned on the reverse hereof.

                       This bond is the only bond 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 said bonds known as General and Refunding Mortgage Bonds,
                     1990 Series B (elsewhere herein referred to as the "1990 Series B Bond"),
                     limited to an aggregate principal amount of $256,932,000, except as
                     otherwise provided in the Indenture hereinafter mentioned. This bond is
                     issued and to be issued under, and is 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 Bankers Trust Company, a corporation of the State of New
                     York, as Trustee, to which Indenture and all indentures supplemental
                     thereto (including the Supplemental Indenture dated as of February 15,
                     1990) 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 15, 1990, 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 principal 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 principal 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.
 
                       The holder of the 1990 Series B Bond, by its acceptance of and holding
                     thereof, consents and agrees that bonds of any series may be issued which
                     mature on a date or dates later than October 1, 2024 and also consents to
                     the deletion from the first paragraph of Section 5 of Article II of the
                     Indenture of the phrase "but in no event later than October 1, 2024." Such
                     holder further agrees that (a) such consent shall, for all purposes of
                     Article XV of the Indenture and without further action on the part of such
                     holder, be deemed the affirmative vote of such holder at any meeting
                     called pursuant to said Article XV for the purpose of approving such
                     deletion, and (b) such deletion shall become effective at such time as not
                     less than eighty-five percent (85%) in principal amount of bonds
                     outstanding under the Indenture shall have consented thereto substan-
                     tially in the manner set forth in Section 3 of Part I of the Supplemental
                     Indenture dated as of February 15, 1990, or in writing, or by affirmative
                     vote cast at a meeting called pursuant to said Article XV, or by any
                     combination thereof.

                       This bond shall be redeemable prior to stated maturity, at the election
                     of the Company on any interest payment date, at the redemption prices
                     calculated in accordance with the formula set forth below on giving notice
                     of such redemption by first class mail, postage prepaid, by or on behalf
                     of the Company not more than ninety (90) days nor less than thirty (30)
                     days prior to the date fixed for redemption to the registered holder of
                     the 1990 Series B Bond.

                       The optional redemption payment of each bond to be redeemed shall be
                     equal to the present worth, on the date of redemption, of the remaining
                     scheduled semi- annual payments of interest and annual retirement of
                     principal of such bond, calculated as follows. Determine the present value
                     of each scheduled semi-annual payment of interest and annual retirement of
                     principal by dividing each payment by the Present Value Divisor (PVD),
                     where:
                                              ________
                                     PVD = (\/ 1.0 + I) (D)
 
                     I = That annual interest rate (which has been adjusted for semi-annual
                         compounding) for U.S. Treasury securities, with comparable maturities as
                         set forth in the Federal Reserve statistical release, designated
                         H.15 (519), or its successor, published at least 4 days but not
                         more than 10 days prior to the optional redemption date. The rate
                         shall be the "This Week" rate for Treasury Constant Maturities.
                         Straight line interpolate to 3 decimal places after rounding the
                         prepayment period to the nearest month (1st-15th round down) to
                         match the remaining term of the bond to be redeemed.
 
                     D = Present value divisor for the preceding 6 month interest period (D
                         equals 1.0 for the period preceding the first period, which is the period
                         from the redemption date to the first scheduled payment date
                         thereafter).
 
                         Add the present value for all scheduled annual retirements of
                         principal and semi-annual payments of interest to determine the sum
                         to be paid upon redemption of each bond.
 
                         If the optional redemption payment is greater than the principal
                         outstanding as of the date of optional redemption, the prepayment
                         results in a premium, plus in each case accrued interest to the date
                         fixed for redemption. If the optional redemption payment is less
                         than the principal outstanding as of the date of the optional
                         redemption, the prepayment results in a discount which shall be
                         deducted from the outstanding principal amount which otherwise would
                         have been paid, plus in each case accrued interest to the date fixed
                         for redemption.
 
                     No redemption pursuant to this paragraph shall be credited to, or relieve
                     the Company to any extent from its obligation to make the principal
                     payment provided for above.
 
                       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 said 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.

TERMS OF BONDS         SECTION 1. The Company hereby creates the Two hundred eighty-fourth
OF 1990 SERIES E.    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, 1990 Series E"
                     (elsewhere herein referred to as the "bonds of 1990 Series E"). The
                     aggregate principal amount of bonds of 1990 Series E shall be limited to
                     the principal amount of 1990 Series B Bond being exchanged, except as
                     provided in Sections 7 and 13 of Article II of the Original Indenture with
                     respect to exchanges and replacements of bonds.
 
                       The bonds of 1990 Series E shall mature on March 31, 2016 and shall be
                     issued in exchange for, and in an aggregate principal amount equal to the
                     principal amount remaining outstanding on, the 1990 Series B Bond as of
                     the date of such exchange. The Bonds of Series E shall be issued as
                     registered bonds without coupons in denominations of $10,000 and any
                     multiple thereof, and shall bear interest, payable semi-annually on March
                     31 and September 30 of each year (commencing on the first March 31 or
                     September 30 following the date of such exchange), at the rate of seven
                     and 904/1000 per centum (7.904%) per annum until the principal 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. Except as otherwise specifically provided in
                     this Supplemental Indenture, the principal of and interest on the bonds of
                     1990 Series E shall be payable at the office or agency of the Company in
                     the Borough of Manhattan, The City of New York, The 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. The interest on
                     bonds of 1990 Series E, whether in temporary or definitive form, shall be
                     payable without presentation of such bonds and (subject to the provisions
                     of this Section 1) only to or upon the written order of the registered
                     holders thereof.
 
                       Each bond of 1990 Series E shall be dated the date of its authentication
                     and interest shall be payable on the principal represented thereby from
                     the March 31 or September 30 next preceding the date thereof to which
                     interest has been paid on bonds of 1990 Series E, unless the bond is
                     authenticated on a date to which interest has been paid, in which case
                     interest shall be payable from the date of authentication.
 
                       The bonds of 1990 Series E 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 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 1990
                     Series E). Until bonds of 1990 Series E 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 1990
                     Series E in temporary form, as provided in Section 10 of Article II of the
                     Indenture. Temporary bonds of 1990 Series E, if any, may be printed and
                     may be issued in authorized denominations in substantially the form of
                     definitive bonds of 1990 Series E, 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.

                       Interest on any bond of 1990 Series E which 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 day of March or September as
                     the case may be (whether or not a business day) next preceding such
                     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 1990 Series E, 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 1990 Series E 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 1990 Series E 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 1990 Series
                     E 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.

                     utilize, directly or indirectly, the proceeds of and is not in
                     anticipation of any refunding operation involving borrowing at an interest
                     cost to the Company, computed in accordance with generally accepted
                     financial practice, of less than 7.904% per annum, and (iii) at the
                     election of the Company on any date prior to maturity, commencing March 31
                     of the eleventh (11th) calendar year subsequent to initial issuance, as a

                     (expressed as percentages of the principal amount thereof) plus in each
                     case (whether through operation of the sinking fund or otherwise) accrued
                     interest to the date fixed for redemption:

                     herein and as specified in Article IV of the Indenture upon giving notice
                     of such redemption by first class mail, postage prepaid, by or on behalf
                     of the Company at least thirty (30) days prior to the date fixed for

                     sinking fund, in each case in satisfaction of all or any part of the
                     amount of any sinking fund payment. Each such bond of 1990 Series E shall
                     be received or credited for such purpose by the Trustee at the principal

                     redeemed. The treasurer's certificate shall also state that bonds of 1990
                     Series E forming the basis of any such credit do not include any bonds of
                     1990 Series E which have been called for redemption for the sinking fund

                     of 1990 Series E to be redeemed upon the next ensuing March 31 in the

                     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,

                     purposes of Article XV of the Indenture and without further action on the
                     part of such holders, be deemed the affirmative vote of such holders at
                     any meeting called pursuant to said Article XV for the purpose of
                     approving such deletion, and (b) such deletion shall become effective at
                     such time as not less than eighty-five percent (85%) in principal amount
                     of bonds outstanding under the Indenture shall have consented thereto

                     principal by dividing each payment by the Present Value Divisor (PVD),
                     where:
                                             __________
                                    PVD = (\/ 1.0 + I) (D)

                     I = That annual interest rate (which has been adjusted for semi-annual
                         compounding) for U.S. Treasury securities, with comparable maturities as
                         set forth in the Federal Reserve statistical release, designated
                         H.15 (519), or its successor, published at least 4 days but not
                         more than 10 days prior to the optional redemption date. The rate
                         shall be the "This Week" Rate for Treasury Constant Maturities.
                         Straight line interpolate to 3 decimal places after rounding the
                         prepayment period to the nearest month (1st-15th round down) to
                         match the remaining term of the bond to be redeemed.

                     D = Present value divisor for the preceding 6 month interest period (D
                         equals 1.0 for the period preceding the first period, which is the period
                         from the redemption date to the first scheduled payment date
                         thereafter).
                          
                         Add the present value for all scheduled annual retirements of
                         principal and semi-annual payments of interest to determine the sum
                         to be paid upon redemption of each bond.
                          
                         If the optional redemption payment is greater than the principal
                         outstanding as of the date of optional redemption, the prepayment
                         results in a premium, plus in each case accrued interest to the date
                         fixed for redemption. If the optional redemption payment is less
                         than the principal outstanding as of the date of the optional
                         redemption, the prepayment results in a discount which shall be
                         deducted from the outstanding principal amount which otherwise would
                         have been paid, plus in each case accrued interest to the date fixed
                         for redemption.

                       Any partial redemption shall, as the principal portion of such
                     redemption, be no less than $100,000. No redemption pursuant to this
                     paragraph shall be credited to, or relieve the Company to any extent from
                     its obligation to make the principal payments provided for in Section 1
                     hereof.
 
                       On or before the first day of February or August in each year,
                     commencing September 1 1990, the Company will deliver to the Trustee a
                     treasurer's certificate, which shall be irrevocable, specifying the
                     principal amount of bonds to be optionally redeemed and accrued interest
                     on such bonds on the next ensuing March 31 or September 30, or the first
                     business day thereafter, respectively. The Trustee shall, upon the receipt
                     of the treasurer's certificate, cause notice of the redemption thereof to
                     be given in the name of and at the expense of the Company in the manner
                     herein provided for. On or before noon of the business day preceding the
                     day of prepayment, the Company will advise the Trustee of the applicable
                     premium or discount applicable to such prepayment. Such notice having been
                     duly given, the redemption of bonds of 1990 Series C shall be made upon
                     the terms and in the manner and with the effect hereinabove provided for
                     with respect to redemptions. A treasurer's certificate shall not be
                     required if no bonds of a series are to be redeemed under this paragraph.
 
EXCHANGE.              SECTION 3. At the option of the holder, upon written request made at
                     least forty-five (45) days prior to an interest payment date and subject
                     to the terms of the Indenture and compliance with applicable securities
                     laws, the 1990 Series C Bond shall be exchangeable, in whole but not in
                     part, for bonds of 1990 Series F (as hereinafter described) in an
                     aggregate principal amount equal to the aggregate amount of unpaid
                     principal which shall remain outstanding on the 1990 Series C Bond as of
                     the date of such exchange. Such exchange shall occur only on an interest
                     payment date for the 1990 Series C Bond at the office of the Trustee in
                     the Borough of Manhattan, The City of New York, The State of New York.
 
                       The 1990 Series C Bond shall bear a legend stating that such bond has
                     not been registered under the United States Securities Act of 1933, as
                     amended (the "Act") and that as a consequence such bond may not be
                     offered, sold or otherwise transferred, whether or not for consideration,
                     unless registered under such Act or pursuant to an exemption from such
                     registration applicable to such offer, sale or other transfer, and may
                     bear such other legends as may be necessary to comply with any law or with
                     any rules or regulations made pursuant thereto.
 
CONSENT.               SECTION 4. The holder of the 1990 Series C Bond, by its acceptance of
                     and holding thereof, consents and agrees that bonds of any series may be
                     issued which mature on a date or dates later than October 1, 2024 and also

                     meeting called pursuant to said Article XV for the purpose of approving
                     such deletion, and (b) such deletion shall become effective at such time

                     outstanding under the Indenture shall have consented thereto substan-
                     tially in the manner set forth in this Section 4, or in writing, or by

                       THE DETROIT EDISON COMPANY (hereinafter called the "Company"), a

                     United States of America, the principal sum of $85,475,000, together with
                     interest at the rate specified in the title hereof on the amount of said
                     principal sum remaining unpaid from time to time from January 3, 1990, and
                     after the first interest payment hereon from the most recent date to which
                     interest has been paid hereon, 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 on the reverse hereof and in the supplemental indenture pursuant
                     to which this bond has been issued. Interest shall be due and payable in
                     49 consecutive semi-annual payments on March 31 and September 30 in each
                     year, commencing on March 31, 1990, and principal shall be due and payable
                     in 25 consecutive annual payments on March 31, in each year, commencing on

                       Payments of principal, premium, if any, and interest on this bond are to
                     be made by bank wire transfer in immediately available funds to the holder

                       In the event any semi-annual payment is not made when due, the amount
                     payable shall be such payment, plus interest thereon at the interest rate
                     of one and one-half times the rate to be determined by the Secretary of
                     the Treasury taking into consideration the prevailing market yield on the
                     remaining maturity of the most recently auctioned 13-week U.S. Treasury
                     bills, from the due date to the date of payment. Upon the expiration of
                     each successive 91-day period following the scheduled payment date for any

                     paragraph and such rate shall be applied to the outstanding payment and
                     all late charges accrued thereon.
 
                       When any payment date falls on a Saturday, Sunday or a day on which the
                     Federal Reserve Bank of New York or the Trustee is not open for business,
                     all payments shall be payable on the first day thereafter on which the

                       At the written request of the registered holder hereof made at least
                     forty-five (45) days in advance of an interest payment date, this bond
                     shall be exchangeable, in whole but not in part, on any interest payment
                     date in an aggregate principal amount equal to the amount of unpaid
                     principal which shall remain outstanding on this bond as of the date of
                     such exchange (after giving effect to the payment of principal hereon on
                     the date of such exchange), all as provided, to the extent and in the
                     manner specified in the Indenture and the Supplemental Indenture
                     hereinafter mentioned on the reverse hereof.

                     Bankers Trust Company, the Trustee under the Indenture hereinafter
                     mentioned on the reverse hereof, or its successor thereunder, shall have

                                             [FORM OF REVERSE OF BOND]
 
                       This bond is the only bond 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 said bonds known as General and Refunding Mortgage Bonds,
                     1990 Series C (elsewhere herein referred to as the "1990 Series C Bond"),
                     limited to an aggregate principal amount of $85,475,000, except as
                     otherwise provided in the Indenture hereinafter mentioned. This bond is
                     issued and to be issued under, and is 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 Bankers Trust Company, a corporation of the State of New
                     York, as Trustee, to which Indenture and all indentures supplemental
                     thereto (including the Supplemental Indenture dated as of February 15,
                     1990) 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 15, 1990, 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 principal 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 principal 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

                       This bond shall be redeemable prior to stated maturity, at the election
                     of the Company on any interest payment date, at the redemption prices
                     calculated in accordance with the formula set forth below on giving notice
                     of such redemption by first class mail, postage prepaid, by or on behalf
                     of the Company not more than ninety (90) days nor less than thirty (30)
                     days prior to the date fixed for redemption to the registered holder of
                     the 1990 Series C Bond.

                       The optional redemption payment of each bond to be redeemed shall be
                     equal to the present worth, on the date of redemption, of the remaining
                     scheduled semi- annual payments of interest and annual retirement of
                     principal of such bond, calculated as follows. Determine the present value
                     of each scheduled semi-annual payment of interest and annual retirement of
                     principal by dividing each payment by the Present Value Divisor (PVD),
                     where:
                                                      ____________
                                             PVD = (\/1.0 + I) (D)
 
                        I = That annual interest rate (which has been adjusted for semi-annual
                            compounding) for U.S. Treasury securities, with comparable maturities 
                            as set forth in the Federal Reserve statistical release, designated
                            H.15 (519), or its successor, published at least 4 days but not
                            more than 10 days prior to the optional redemption date. The rate
                            shall be the "This Week" rate for Treasury Constant Maturities.
                            Straight line interpolate to 3 decimal places after rounding the
                            prepayment period to the nearest month (1st-15th round down) to
                            match the remaining term of the bond to be redeemed.
 
                       D = Present value divisor for the preceding 6 month interest period (D
                           equals 1.0 for the period preceding the first period, which is the 
                           period from the redemption date to the first scheduled payment date
                           thereafter).
 
                           Add the present value for all scheduled annual retirements of
                           principal and semi-annual payments of interest to determine the sum
                           to be paid upon redemption of each bond.
 
                           If the optional redemption payment is greater than the principal
                           outstanding as of the date of optional redemption, the prepayment
                           results in a premium, plus in each case accrued interest to the date
                           fixed for redemption. If the optional redemption payment is less
                           than the principal outstanding as of the date of the optional
                           redemption, the prepayment results in a discount which shall be
                           deducted from the outstanding principal amount which otherwise would
                           have been paid, plus in each case accrued interest to the date fixed
                           for redemption.
 
                     No redemption pursuant to this paragraph shall be credited to, or relieve
                     the Company to any extent from its obligation to make the principal
                     payment provided for above.
 
                       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 said 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.

TERMS OF BONDS         SECTION 1. The Company hereby creates the Two hundred eighty-sixth
OF 1990 SERIES F.    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, 1990 Series F"
                     (elsewhere herein referred to as the "bonds of 1990 Series F"). The
                     aggregate principal amount of bonds of 1990 Series F shall be limited to
                     the principal amount of 1990 Series C Bond being exchanged, except as
                     provided in Sections 7 and 13 of Article II of the Original Indenture with
                     respect to exchanges and replacements of bonds.
 
                       The bonds of 1990 Series F shall mature on March 31, 2014 and shall be
                     issued in exchange for, and in an aggregate principal amount equal to the
                     principal amount remaining outstanding on, the 1990 Series C Bond as of
                     the date of such exchange. The bonds of 1990 Series F shall be issued as
                     registered bonds without coupons in denominations of $10,000 and any
                     multiple thereof, and shall bear interest, payable semi-annually on March
                     31 and September 30 of each year (commencing on the first March 31 or
                     September 30 following the date of such exchange), at the rate of eight
                     and 357/1000 per centum (8.357%) per annum until the principal 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. Except as otherwise specifically provided in
                     this Supplemental Indenture, the principal of and interest on the bonds of
                     1990 Series F shall be payable at the office or agency of the Company in
                     the Borough of Manhattan, The City of New York, The 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. The interest on
                     bonds of 1990 Series F, whether in temporary or definitive form, shall be
                     payable without presentation of such bonds and (subject to the provisions
                     of this Section 1) only to or upon the written order of the registered
                     holders thereof.
 
                       Each bond of 1990 Series F shall be dated the date of its authentication
                     and interest shall be payable on the principal represented thereby from
                     the March 31 or September 30 next preceding the date thereof to which
                     interest has been paid on bonds of 1990 Series F, unless the bond is
                     authenticated on a date to which interest has been paid, in which case
                     interest shall be payable from the date of authentication.
 
                       The bonds of 1990 Series F 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 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 1990
                     Series F). Until bonds of 1990 Series F in definitive form are ready for

                     Indenture, dated as of October 1, 1924, duly executed by the Company to
                     Bankers Trust Company, a corporation of the State of New York, as Trustee,
                     to which Indenture and all indentures supplemental thereto (including the
                     Supplemental Indenture dated as of February 15, 1990) 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 15,
                     1990, 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 principal 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 principal 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

                       The holders of the bonds of 1990 Series F, by their acceptance of and

                     2024,". Such holders further agree that (a) such consent shall, for all
                     purposes of Article XV of the Indenture and without further action on the
                     part of such holders, be deemed the affirmative vote of such holders at
                     any meeting called pursuant to said Article XV for the purpose of
                     approving such deletion, and (b) such deletion shall become effective at
                     such time as not less than eighty-five percent (85%) in principal amount
                     of bonds outstanding under the Indenture shall have consented thereto
                     substantially in the manner set forth in Section 3 of Part I of the
                     Supplemental Indenture dated as of February 15, 1990, or in writing, or by
