been specifically mortgaged and pledged hereunder, unless and until such default shall be
remedied or waived and possession of the mortgaged and pledged property restored to the
Company, its successors or assigns, and provided further, that upon the taking of such

existing on such excepted property.

            And the Company does hereby covenant and agree with the Trustees, and the
Trustees with the Company, as follows:

                                           PART I

            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 holders of the bonds and interest obligations issued
and to be issued under the Amended Indenture, as from time to time amended and
supplemented, without preference of any bond over any other bond by reason of priority in
date of issuance, negotiation, time of maturity, or for any other cause whatsoever, 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 any time hereafter outstanding

conditions and for the uses set forth in the Amended Indenture, as from time to time
amended and supplemented.

                                          PART II

            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.
Page 5

                                          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 2010A 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,
Page 7

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

      SOUTHERN CALIFORNIA EDISON COMPANY, a corporation organized and existing under and by
virtue of the laws of the State of California (hereinafter called the "Company"), for value
received, hereby promises to pay to _____________________, the registered owner hereof, the
principal sum of $500,000,000 on March 15, 2040, and to pay interest on the unpaid
principal amount hereof to the registered owner hereof from March 11, 2010, until said
principal sum shall be paid, at the rate of 5.50% per annum, payable semiannually on March
15 and September 15 in each year, beginning September 15, 2010.  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.

Page 3

      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 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 2010A, Due 2040," 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 Nineteenth Supplemental Indenture, dated as of March 9,
2010, 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 15 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.

Page 4

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 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 J.P. Morgan Securities Inc. ("J.P. Morgan") 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) Citigroup Global Markets Inc. ("Citigroup"),
Credit Suisse Securities (USA) LLC ("Credit Suisse"), J.P. Morgan, and RBS Securities Inc.
("RBS") 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 Citigroup,
Credit Suisse, J.P. Morgan, or RBS, or their successors, provided, however, that if
Citigroup, Credit Suisse, J.P. Morgan, or RBS, 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 2010A 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 2010A 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 execution and attestation to be by manual or facsimile
