incorporated by reference herein and made a part hereof as fully as though set forth at length herein.

                                                 PART III

                  All of the terms appearing herein shall be defined as the same are now defined under
the provisions of the Amended Indenture, except when expressly herein otherwise defined.

                                                 PART IV

                  Pursuant to Section 1 of Article Five of the Original Indenture, as amended by
Part IV, Subpart C, of the Sixth Supplemental Indenture, dated as of September 1, 1940, the notice to be
given with respect to the redemption of the Bonds in whole or in part, shall be limited to and shall
consist of the giving by the Company or The Bank of New York Mellon Trust Company, N.A., Trustee, of a
notice in writing (including by facsimile transmission) of such redemption, at least 30 days, but not
more than 60 days, prior to the date fixed for redemption to the holder of each Bond called for
redemption at the holder's last address shown on the registry books of the Company.  Failure to so
provide such notice to the holder of any Bond shall not affect the validity of the redemption
proceedings with respect to any other Bond.

                                                  PART V

                  The Bonds shall be in substantially the form set forth in a resolution of the Board of
Directors or the Executive Committee of the Board of Directors of the Company, or a certificate
evidencing action by an officer or officers of the Company, and may have placed thereon such letters,
numbers or other marks of identification and such legends or endorsements as set forth in this
Supplemental Indenture or as may be required to comply with the Securities Act of 1933, as amended (the
"Securities Act"), any other laws, any other rules of the Securities and Exchange Commission or any
securities exchange, or as may, consistently herewith, be determined to be necessary or appropriate by
the officers executing the Bonds, as evidenced by their execution of the Bonds.

                  The Bonds initially shall be represented by one or more securities in registered,
global form without interest coupons ("Global Bonds").  Each certificate for Global Bonds shall
represent the aggregate principal of outstanding Bonds of a series from time to time endorsed thereon
and the aggregate principal amount of outstanding Bonds of a series represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges and redemptions.  Any endorsement of
a Global Bond certificate to reflect the amount of any increase or decrease in the aggregate principal
amount of outstanding Bonds represented thereby shall be made by The Bank of New York Mellon Trust
Company, N.A., Trustee, as registrar for the Bonds (the "Bond Registrar"), in accordance with
instructions given by the registered holder thereof.

                  The Company initially appoints The Depository Trust Company ("DTC") to act as
depositary with respect to the Global Bonds (together with any successor, the "Depositary").  Each
certificate representing Global Bonds shall bear a legend in substantially the following form (the
"Global Bond Legend"):

                  UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY
                  TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO SOUTHERN CALIFORNIA EDISON COMPANY
                  OR ITS AGENT FOR REGISTRATION OR TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE
                  ISSUED IS REGISTERED IN THE NAME OF CEDE and CO. OR IN SUCH OTHER NAME AS IS REQUESTED
                  BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE and CO. OR TO
                  SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
                  TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
                  WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE and CO., HAS AN INTEREST HEREIN.

                                                Page 6


                  Beneficial interests in the Global Bonds may not be exchanged for Bonds in
certificated form ("Certificated Bonds") except in the limited circumstances set forth below in this
Supplemental Indenture.  Certificates representing Certificated Bonds will not bear the Global Bond
Legend.

                                                 PART VI

                  The transfer and exchange of Global Bonds or beneficial interests in Global Bonds
shall be effected through the Depositary, in accordance with the terms of the Amended Indenture
(including the restriction on transfer set forth herein) and the procedures of the Depositary.

                  A Global Bond may be exchanged for Certificated Bonds if (a) the Depositary for the
Global Bond notifies the Company that the Depositary is unwilling or unable to continue as to act as
Depositary for the Global Bond or has ceased to be a clearing agency registered under the Securities
Exchange Act of 1934, and in either case the Company fails to appoint a successor Depositary within
90 days after delivery of such notice; (b) the Company notifies the Bond Registrar in writing that it has
elected to cause the issuance of Certificated Bonds; or (c) there has occurred and is continuing a
default with respect to the Bonds under the Amended Indenture.  Certificated Bonds delivered in exchange
for any Global Bond or beneficial interests in Global Bonds will be executed by the Company,
authenticated by The Bank of New York Mellon Trust Company, N.A., as Trustee, registered in the names,
and issued in any approved denominations, requested by or on behalf of the Depositary (in accordance
with its customary procedures).

                  When Certificated Bonds are presented to the Bond Registrar with a request to register
the transfer of the Certificated Bonds or to exchange such Certificated Bonds for an equal principal
amount of Certificated Bonds of other authorized denominations, the Bond Registrar shall register the
transfer or make the exchange as requested if its requirements for such transactions are met.

                                                 PART VII

                  All, but only, the duties, responsibilities, liabilities, immunities, rights, powers,
and indemnities against liability, of the Trustees and each of them, with respect to the trust created
by the Amended Indenture, are hereby assumed by and given to the Trustees, and each of them, with
respect to the trust hereby created, and are so assumed and given subject to all the terms and
provisions with respect thereto as set forth in the Amended Indenture, as fully and to all intents and
purposes as if the same were herein set forth at length; and this Supplemental Indenture is executed by
the Trustees for the purpose of evidencing their consent to the foregoing.

                  The recitals contained herein, except the recital that the Trustees have each duly
determined to execute and deliver this Supplemental Indenture, shall be taken as the statements of the
Company, and the Trustees assume no responsibility for the correctness thereof.  The Trustees make no
representations as to the validity of this Supplemental Indenture.

                                                PART VIII

                  The Series 2010B Bonds need not be issued at the same time and such series may be
reopened at any time, without notice to or the consent of any then-existing holder or holders of any
Bond, for issuances of additional Bonds in an unlimited principal amount.  Any such additional Bonds
will have the same interest rate, maturity and other terms as those of that series initially issued,
except for payment of interest accruing prior to the original issue date of such additional Bonds and,
if applicable, for the first interest payment date following such original issue date.

                                                 PART IX

                  As amended and supplemented by this Supplemental Indenture, the Amended Indenture is
in all respects ratified and confirmed, and the Original Indenture and all said indentures supplemental
thereto including this Supplemental Indenture, shall be read, taken, and considered as one instrument,
and the Company agrees to conform to and comply with all and singular the terms, provisions, covenants,
and conditions set forth therein and herein.

                                                  PART X

                  In case any one or more of the provisions contained in this Supplemental Indenture
should be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not affect any other provisions contained in this Supplemental Indenture, and, to
the extent and only to the extent that any such provision is invalid, illegal, or unenforceable, this
Supplemental Indenture shall be construed as if such provision had never been contained herein.

                                                 PART XI

                  This Supplemental Indenture may be simultaneously executed and delivered in any number
of counterparts, each of which, when so executed and delivered, shall be deemed to be an original.
