            The Trustees shall have and hold all and singular the properties
conveyed, assigned, mortgaged and pledged hereby or by the Amended Indenture,
including property hereafter as well as heretofore acquired, in trust for the
equal and proportionate benefit and security of all present and future

except as otherwise in the Amended Indenture, as from time to time amended
and supplemented, permitted, and to secure the payment of all bonds now or at

            Article I to Article Twenty-One, inclusive, of the Amended
Indenture are hereby 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.

page 5

                                   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 from time to time endorsed thereon and the
aggregate principal amount of outstanding Bonds 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 & CO. OR IN
            SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE
            OF DTC (AND ANY PAYMENT IS MADE TO CEDE & 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 & CO., HAS AN INTEREST HEREIN.

            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.

Page 6

                                   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

      SOUTHERN CALIFORNIA EDISON COMPANY, a corporation organized and

(hereinafter called the "Company"), for value received, hereby promises to
pay to _____________________, the registered owner hereof, the principal sum

principal amount hereof to the registered owner hereof from August 18, 2008,
until said principal sum shall be paid, at the rate of 5.50% per annum,
payable semiannually on February 15 and August 15 in each year, beginning
February 15, 2009.  Such interest shall be paid to the person in whose name
this Bond is registered at the close of business on (1) the business day
immediately preceding the interest payment date if this Bond is in book-entry
only form, or (2) the 15th calendar day before each interest payment date if
this Bond is not in book-entry only form.

      The principal of and interest on this Bond are payable at the offices
of The Bank of New York Mellon Trust Company, N.A., as Trustee, in Chicago,
Illinois, or at such other agency or

Page 3

agencies as may be designated by the
Company, in such coin or currency of the United States of America as at the
time of payment is legal tender for public and private debts.

      This Bond is one of a series, designated as "Series 2008B, Due 2018,"
of a duly authorized issue of bonds of the Company, known as its "First and
Refunding Mortgage Bonds," issued and to be issued in one or more series
under and all equally and ratably secured by a Trust Indenture dated as of
October 1, 1923, and indentures supplemental thereto, including the One
Hundred Sixteenth Supplemental Indenture, dated as of August 13, 2008, which
have been duly executed, acknowledged and delivered by the Company to The
Bank of New York Mellon Trust Company, N.A. and D. G. Donovan, or one of
their predecessors, as Trustees, to which original indenture and indentures
supplemental thereto (collectively, the "Trust Indenture") reference is
hereby made for a description of the property, rights and franchises thereby
mortgaged and pledged, the nature and extent of the security thereby created,
the rights of the holders of this Bond and of the Trustees in respect of such
security, and the terms, restrictions and conditions upon which the bonds are
issued and secured.

      This Bond may be redeemed, in whole or in part, at the option of the
Company, at any time prior to its maturity, after notice given in writing
(including by facsimile transmission) to the registered owner hereof at the
last address shown on the registry books of the Company, by the Company or
The Bank of New York Mellon Trust Company, N.A., as Trustee, at least
30 days, but not more than 60 days, before the date fixed for redemption, at
a redemption price equal to the greater of (1) the principal amount redeemed
or (2) the sum of the present values of the remaining scheduled payments of
principal and interest (excluding any interest accrued from the immediately
preceding interest payment date to the date fixed for redemption) on this
Bond being redeemed, discounted to the date fixed for redemption on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Treasury Yield plus 25 basis points, plus in each case accrued
and unpaid interest to the date fixed for redemption.

      "Treasury Yield" means, for any date fixed for redemption, the rate per
year equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed
as a percentage of its principal amount) equal to the Comparable Treasury
Price for the date fixed for redemption.

      "Comparable Treasury Issue" means the United States Treasury security
or securities selected by an Independent Investment Banker as having an
actual or interpolated maturity comparable to the remaining term to stated
maturity of this Bond that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining term of
this Bond.

      "Comparable Treasury Price" means, for any date fixed for redemption,
(1) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding the date fixed for redemption, as set forth in the
daily statistical release (or any successor release) published by the Federal
Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for
U.S. Government Securities" or (2) if that release (or any successor release)
is not published or does not contain those prices on that business day,
(A) the average of the Reference Treasury Dealer

Page 4

Quotations for the date
fixed for redemption, or (B) if the Independent Investment Banker obtains
fewer than four Reference Treasury Dealer Quotations, the average of all of
the Quotations.

      "Independent Investment Banker" means Merrill Lynch, Pierce, Fenner &
Smith Incorporated ("Merrill Lynch") or its successor or, if such firm or its
successor is unwilling or unable to select the Comparable Treasury Issue, one
of the remaining Reference Treasury Dealers appointed by The Bank of New York
Mellon Trust Company, N.A., as Trustee, after consultation with the Company.

      "Reference Treasury Dealer" means (1) Credit Suisse Securities (USA)
LLC ("Credit Suisse"), Merrill Lynch and Greenwich Capital Markets, Inc.
("RBS Greenwich Capital") and any other primary U.S. Government securities
dealer in the United States of America (a "Primary Treasury Dealer")
designated by, and not affiliated with Credit Suisse, Merrill Lynch or RBS
Greenwich Capital, or their successors, provided, however, that if Credit
Suisse, Merrill Lynch or RBS Greenwich Capital, or any of their designees,
ceases to be a Primary Treasury Dealer, the Company will appoint another
Primary Treasury Dealer as a substitute, and (2) any other Primary Treasury
Dealer selected by the Company.

      "Reference Treasury Dealer Quotations" means, for each Reference
Treasury Dealer and any date fixed for redemption, the average, as determined
by the Independent Investment Banker, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Independent Investment Banker by
the Reference Treasury Dealer at 5:00 p.m. on the third business day
preceding the date fixed for redemption.

      If the Company elects to redeem fewer than all the Series 2008B Bonds,
The Bank of New York Mellon Trust Company, N.A., as Trustee, will select the
particular bonds to be redeemed on a pro rata basis, by lot or by such other
method of random selection, if any, that The Bank of New York Mellon Trust
Company, N.A., as Trustee, deems fair and appropriate.

      Any notice of redemption, at the Company's option, may state that the
redemption will be conditional upon receipt by the paying agent, on or prior
to the date fixed for the redemption, of money sufficient to pay the
principal of and premium, if any, and interest, if any, on the Series 2008B
Bonds to be redeemed and that if the money has not been so received, the
notice will be of no force and effect and the Company will not be required to
redeem this Bond.

      The Trust Indenture makes provision for a Special Trust Fund and
permits the use of moneys therein for the purpose, among others, of redeeming
or purchasing this Bond.

      If default shall be made in the payment of any installment of principal
of or interest on this Bond or in the performance or observance of any of the
covenants and agreements contained in the Trust Indenture, and such default
shall continue as provided in the Trust Indenture, then the principal of this
Bond may be declared and become due and payable as provided in the Trust
Indenture.

Page 5

      This Bond is transferable only on the books of the Company at any of
the places designated above for the payment of the principal of and premium,
if any, or interest on this Bond, or at such other agency or agencies as may
be designated by the Company, by the registered owner or by an attorney of
such owner duly authorized in writing, on surrender hereof properly endorsed,
and upon such surrender hereof, and the payment of charges, a new registered
bond or bonds of this series, of an equal aggregate principal amount, will be
issued to the transferee in lieu hereof, as provided in the Trust Indenture.

      The terms of the Trust Indenture may be modified as set forth in the
Trust Indenture; provided, however, that, among other things, (1) the
obligation of the Company to pay the principal of and premium, if any, and
interest on all bonds outstanding under the Trust Indenture, as at the time
in effect, shall continue unimpaired, (2) no modification shall give any of
said bonds any preference over any other of said bonds, and (3) no
modification shall authorize the creation of any lien prior to the lien of
the Trust Indenture on any of the trust property.

      No recourse shall be had for the payment of the principal of and
premium, if any, or interest on this Bond, or any part thereof, or for or on
account of the consideration herefor, or for any claim based hereon, or
otherwise in respect hereof, or of the Trust Indenture, against any past,
present or future stockholder, officer or director of the Company or of any
predecessor or successor company, whether for amounts unpaid on stock
subscriptions, or by virtue of any statue or constitution, or by the
enforcement of any assessment or penalty, or because of any representation or
inference arising from the capitalization of the Company or of such
predecessor or successor company, or otherwise; all such liability being, by
the acceptance hereof and as a part of the consideration for the issue
hereof, expressly released.

      This Bond shall not be valid or obligatory for any purpose until it
shall have been authenticated by the execution of the certificate of
authentication hereon of The Bank of New York Mellon Trust Company, N.A., as
Trustee, or its successor in trust.

      IN WITNESS WHEREOF, Southern California Edison Company has caused this
Bond to be executed in its name by its President or one of its Vice
Presidents and its corporate seal to be hereto affixed and attested by its
Secretary or one of its Assistant Secretaries, as of ____________, ____, such
