                     Supplemental Indenture, to be designated, and to be distinguished from the
                     bonds of all other series, by the title "General and Refunding Mortgage
                     Bonds, 20  Series  " (elsewhere herein referred to as the "bonds of 20
                     Series  "). The aggregate principal amount of bonds of 20  Series  shall
                     be limited to                 million dollars ($             ), 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 20  Series  shall mature on              and shall be
                     issued as registered bonds without coupons in denominations of $1,000 and

                     rate of                          per centum (   %) per annum [if variable
                     rate, insert variable rate provisions] 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
                     20  Series  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

                     of this Section 1) only to or upon the written order of the registered
                     holders thereof.

                         Each bond of 20  Series  shall be dated the date of its authentication
                     and interest shall be payable on the principal represented thereby from
                     the           or       next preceding the date thereof to which interest
                     has been paid on bonds of 20  Series  , 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, or unless the date of
                     authentication is prior to              , in which case interest shall be
                     payable from                on the bond of 20  Series  originally
                     evidencing the debt represented thereby.

                         The bonds of 20  Series  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 20
                     Series  ). Until bonds of 20  Series  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 20
                     Series  in temporary form, as provided in Section 10 of Article II of the
                     Indenture. Temporary bonds of 20  Series  , if any, may be printed and may
                     be issued in authorized denominations in substantially the form of
                     definitive bonds of 20  Series  , 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.

                     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           day of      or          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

                               [FORM OF REVERSE OF BOND]

                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 said bonds known as General and Refunding Mortgage
         Bonds, 20  Series   (elsewhere herein referred to as the "bonds of 20
         Series  "), limited to an aggregate principal amount of $
         , 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 First Chicago Trust Company of New
         York, a trust company of the State of New York, as successor Trustee,
         to which Indenture and all indentures supplemental thereto (including
         the Supplemental Indenture dated as of                   ) 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                 , 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 alted 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.

                                          If Book-Entry

                [The holder of this bond of 20  Series   hereby consents that
         the Company may, but shall not be obligated to, fix a record date for
         the purpose of determining the holders of bonds of this series
         entitled to consent to any amendment, supplement or waiver. If a
         record date is fixed, those persons who were holders at such record
         date (or their duly designated proxies), and only those persons, shall
         be entitled to consent to such amendment, supplement or waiver or to
         revoke any consent previously given, whether or not such persons
         continue to be holders after such record date. No such consent shall
         be valid or effective for more than 90 days after such record date.]

                This bond is redeemable on 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 ninety (90) days, prior to
         the date fixed for redemption to the registered holder of this bond
         at his last address appearing on the register thereof, in the manner
         and upon the terms provided in the Indenture, at the election of the
         Company on any date as a whole or in part by lot, from time to time,
         at the following redemption prices (expressed

         provided, however, that prior to             , no bonds of 20
         Series  may be redeemed, directly or indirectly, from the proceeds or
         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      % per annum.

           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 20  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.

           The bonds of 20  Series  , including this bond, [shall] [not] be
         entitled or subject to a sinking fund.

           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.

           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 or bonds of the same
         series of authorized denominations for a like aggregate principal
         amount will be issued to the transferee or transferees in exchange
         herefor, and this bond with others of like form may in like manner be
         exchanged for one or more new registered 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.

         of America on the Maturity Date specified above, and to pay interest
         thereon at the rate specified above, at such office or agency, in like
         lawful money, from the Issue Date specified above if the date of this
         bond is prior to the first interest payment date, otherwise from the
         most recent date to which interest has been paid, semi-annually on the
         Interest Payment Dates specified above in each year, to the person in
         whose name this bond is registered at the close of business on the
         applicable Record Date specified above (subject to certain exceptions
         provided in the Indenture hereinafter mentioned), 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 such Indenture hereinafter mentioned on the reverse hereof and in
         the supplemental indenture pursuant to which this bond has been

         Payment Date and on or prior to such Interest Payment Date, then

         been paid, from the Issue Date.

                This bond shall not be valid or become obligatory for any

         under the Indenture hereinafter mentioned on the reverse hereof, or its
         successor thereunder, shall have signed the form of certificate

                 thereto, and is one of a series of General and Refunding
                 Mortgage Bonds known as Secured Medium-Term Notes,       Series
                 (elsewhere herein referred to as the "bonds of         Series
                 "), limited to an aggregate principal amount of , 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
                 First Chicago Trust Company of New York, a trust company of the
                 State of New York, as successor Trustee, to which Indenture and
                 all indentures supplemental thereto (including the Supplemental
                 Indenture dated as of           , ) 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
                                    , ), 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 this bond of       Series  hereby consents that
                 the Company may, but shall not be obligated to, fix a record
                 date for the purpose of determining the holders of bonds of
                 this series entitled to consent to any amendment, supplement or
                 waiver. If a record date is fixed, those persons who were
                 holders at such record date (or their duly designated proxies),
                 and only those persons, shall be entitled to consent to such
                 amendment, supplement or waiver or to revoke any consent
                 previously given, whether or not such persons continue to be
                 holders after such record date. No such consent shall be valid
                 or effective for more than 90 days after such record date.

                   This bond is subject to the redemption provisions specified
                 above.

                   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         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.

                     This bond is entitled to or subject to the sinking fund
                 provisions specified above.

                                       14

                This bond will be subject to repayment at the option of the
         holder hereof on the Optional Repayment Date(s), if any, indicated on
         the face hereof. If no Optional Repayment Dates are set forth on the
         face hereof, this bond shall not be so repaid at the option of the
         holder hereof prior to maturity. On any Optional Repayment Date, this
         bond shall be repayable in whole or in part in increments of $1,000
         (provided that any remaining principal amount hereof shall not be less
         than the minimum authorized denomination hereof) at the option of the
         holder hereof at a repayment price equal to 100% of the principal
         amount to be repaid, together with interest thereon payable to the
         date of repayment. For this bond to be repaid in whole or in part at
         the option of the holder hereof, this bond must be received, with the
         form entitled "Option to Elect Repayment" below duly completed, by the
         Trustee at its corporate trust office at 14 Wall Street, New York,
         New York, or such address which the Company shall from time to time
         notify the holders of the bond, not more than 60 nor less than 30 days
         prior to an Optional Repayment Date. Exercise of such repayment option
         by the Holder hereof shall be irrevocable. If specified above that
         this bond is subject to (i) "Annual Redemption Percentage Reduction"
         or (ii) "Annual Redemption Percentage Increase", then this bond may be
         redeemed in whole or in part at the option of the Company on or after
         the Initial Redemption Date specified on the face hereof on the terms
         set forth above, together with interest accrued and unpaid hereon to
         the date of redemption (except as provided below). If this bond is
         subject to "Annual Redemption Percentage Reduction", the Initial
         Redemption Percentage indicated on the face hereof will be reduced on
         each anniversary of the Initial Redemption Date specified above by the
         Annual Percentage Reduction specified on the face hereof until the
         redemption price of this bond is 100% of the principal amount hereof.
         If this bond is subject to "Annual Redemption Percentage Increase",
         the amount of original issue discount allocable to such short accrual
         period is the Amortized Amount. "Amortized Amount" means the original
         issue discount amortized from the Original Issue Date to the date of
         redemption or declaration, as the case may be, which amortization
         shall be calculated using the "constant yield method" (computed in
         accordance with the rules under the Internal Revenue Code of 1986, as
         amended, and the regulations thereunder, in effect on the date of
         redemption or declaration, as the case may be).

                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.

                If specified above that this bond is subject to "Modified
         Payment upon Acceleration," then (i) if the principal hereof is
         declared to be due and payable as discussed in the preceding
         paragraph, the amount of principal due and payable with respect to
         this bond shall be limited to the sum of the Issue Price specified
         above plus the Amortized Amount, (ii) for the purpose of any vote of
         securityholders taken pursuant to the Indenture prior to the
         acceleration of payment of this bond, the principal amount hereof
         shall equal the amount that would be due and payable hereon,
         calculated as set forth in clause (i) above, if this bond were
         declared to be due and payable on the date of any such vote and (iii)
         for the purpose of any vote of securityholders taken pursuant to the
         Indenture following the acceleration of payment of this bond, the
         principal amount hereof shall equal the amount of principal due and
         payable with respect to this bond, calculated as set forth in clause
         (i) above.

                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 or bonds of the same
         series of authorized denominations for a like aggregate principal
         amount will be issued to the transferee or transferees in exchange
         herefor, and this bond with others of like form may in like manner be
         exchanged for one or more new registered 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.
