ARTICLE I
DEFINITIONS

     SECTION 1.01 DEFINITIONS

     Each term used herein has the meaning assigned to such term in the Base Indenture unless otherwise specifically defined herein, in which case the definition set forth herein shall govern the Bonds issued under this Supplemental Indenture. The following terms, as used herein, have the following meanings:

     “Closing Date” means April 17, 2009.

     “Condemnation” with respect to any property shall have occurred if all or any portion of such property shall have been condemned or taken for any public or quasi-public use under any governmental law, order, or regulation or by right of eminent domain or sold to a municipality or other public body or agency or any other entity having the power of eminent domain or the right to purchase or order the sale of such property (a “Condemning Authority”), or any third-party designated by any such Condemning Authority, under threat of condemnation.

     “Corporate Trust Office” means the office of the Trustee specified in the initial paragraph of this Supplemental Indenture or any other office specified by the Trustee from time to time pursuant to the provisions of the Base Indenture.

     “Make-Whole Amount” shall mean in connection with any redemption or acceleration of the Series FFF Bonds the excess, if any, of (i) the aggregate present value as of the Redemption Date of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the Redemption Date) that would have been payable in respect of such dollar if such redemption had not been made, determined by discounting such amounts at the Reinvestment Rate from the respective dates on which they would have been payable, over (ii) 100% of the principal amount of the Outstanding Series FFF Bonds being redeemed. If the Reinvestment Rate is equal to or higher than 5.90%, the Make-Whole Amount shall be zero.

     “Material Condemnation” shall mean any Condemnation of any property of the Company pursuant to which a condemnation award in excess of $100,000 shall have been received by the Company.

     “Reinvestment Rate” shall mean (1) the sum of 0.50%, plus the yield reported on page “USD” of the Bloomberg Financial Markets Services Screen (or, if not available, any other nationally recognized trading screen reporting on-line intraday trading in the U.S. Government Securities) at 10:00 A.M.

If no maturity exactly corresponds to such Remaining Life to Maturity, yields for the published maturity next longer than the

Remaining Life to Maturity and for the published maturity next shorter than the Remaining Life to Maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.

     “Remaining Life to Maturity” of the principal amount of the Series FFF Bonds being redeemed shall mean, as of the time of any determination thereof, the number of years (calculated to the nearest one-twelfth) which will elapse between the date of determination and the final maturity of the Series FFF Bonds being redeemed.

     “Series FFF Bonds” means the $20,000,000 aggregate principal amount of 5.90% First Mortgage Bonds due November 1, 2017, Series FFF, authenticated and delivered under this Supplemental Indenture.

CERTAIN TERMS AND ISSUANCE OF THE SERIES FFF BONDS

     SECTION 2.01. Designation of Series FFF Bonds.

     The changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture shall be applicable only with respect to, and govern the terms of, the Series FFF Bonds and shall not apply to any other Bonds that have been or may be issued under the Base Indenture unless a supplemental indenture with respect to such other Bonds specifically incorporates such changes, modifications and supplements. Pursuant to this Supplemental Indenture, there is hereby designated a series of Bonds under the Base Indenture entitled “5.90% First Mortgage Bonds due 2017, Series FFF.”

     SECTION 2.02. Aggregate Principal Amount.

     The aggregate principal amount of the Series FFF Bonds which may be authenticated and delivered pursuant to this Supplemental Indenture is $20,000,000, except for Series FFF Bonds authenticated and delivered in accordance with Sections 2.15, 2.16, 2.18, 4.07 and 12.06 of the Base Indenture.

     SECTION 2.03. Form; Payment of Interest and Principal on Series FFF Bonds.

     (a) General. Without limiting the foregoing provisions of this Article II, the Series FFF Bonds shall be issued as Definitive Bonds substantially in the form set forth in EXHIBIT A hereto. The Series FFF Bonds will be issued in denominations of $1,000 and integral multiples thereof. To the extent that any provision of the Definitive Bonds representing the Series FFF Bonds conflicts with the express provisions of this Supplemental Indenture or the Base Indenture, this Supplemental Indenture or the Base Indenture shall govern and be controlling.

     (b) Payment of Interest and Principal on Series FFF Bonds. The Series FFF Bonds will mature on November 1, 2017 and will bear interest at the rate of 5.90% per annum. Interest on the Series FFF Bonds will be payable semi-annually in arrears on May 1 and November 1 of each year to the Holders thereof at the close of business on the immediately preceding April 15 and October 15 of each year. Interest on the Series FFF Bonds will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the Closing

Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

     Overdue principal (including any overdue required or optional prepayment of principal) and premium, if any, and (to the extent legally enforceable) any overdue installment of interest shall bear interest at the rate of 7.90% per annum after the date due, whether by acceleration or otherwise, until paid.

The Company acknowledges, and the parties hereto agree, that each Holder of a Series FFF Bond has the right to maintain its investment in the Series FFF Bonds free from repayment by the Company (except as specifically provided for by the terms of the Series FFF Bonds), and that the provision for payment of a Make-Whole Amount by the Company in the event that the Series FFF Bonds are prepaid or accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

ARTICLE III
OPTIONAL REDEMPTION

     SECTION 3.01. Optional Redemption with Premium.

     Upon compliance with the notice provisions set forth in Article IV of the Base Indenture, the Company shall have the privilege, at any time and from time to time, of redeeming the Outstanding Series FFF Bonds, either in whole or in part (but if in part then in a minimum principal amount of $100,000) by redemption of the principal amount of the Series FFF Bonds, or portion thereof to be redeemed, and accrued interest thereon to the Redemption Date, together with a premium equal to the Make-Whole Amount, determined as of five Business Days prior to the Redemption Date pursuant to this Section 3.01.

Any optional redemption made pursuant to this Section 3.02 shall be without premium.

     SECTION 3.03. Pro Rata Redemption.

     SECTION 4.05. Counterparts.

     The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Supplemental Indenture.

     SECTION 4.08. Trustee and Supplemental Indenture.

The terms of the Series FFF Bonds include those stated in the Base Indenture and the Supplemental Indenture and those made part of the Base Indenture and the Supplemental Indenture by reference to the TIA. Terms defined in the Base Indenture and the

Supplemental Indenture and not defined herein have the meanings ascribed thereto in the Base Indenture and Supplemental Indenture. The Series FFF Bonds are subject to all such terms, and Holders are referred to the Base Indenture, the Supplemental Indenture and the TIA for a statement of those terms.

     The Series FFF Bonds are secured obligations of the Company known generally as First Mortgage Bonds.

     5. OPTIONAL REDEMPTION WITH PREMIUM

     Upon compliance with the notice provisions set forth in Article IV of the Base Indenture, the Company shall have the privilege, at any time and from time to time, of redeeming the Outstanding Series FFF Bonds, either in whole or in part (but if in part then in a minimum principal amount of $100,000) by redemption of the principal amount of the Series FFF Bonds, or portion thereof to be redeemed, and accrued interest thereon to the Redemption Date, together with a premium equal to the Make-Whole Amount, determined as of five Business Days prior to the Redemption Date pursuant to this Section 3.01.

     “Make-Whole Amount” shall mean in connection with any redemption or acceleration of the Series FFF Bonds the excess, if any, of (i) the aggregate present value as of the date of such redemption of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the Redemption Date) that would have been payable in respect of such dollar if such redemption had not been made, determined by discounting such amounts at the Reinvestment Rate from the respective dates on which they would have been payable, over (ii) 100% of the principal amount of the Outstanding Series FFF Bonds being redeemed. If the Reinvestment Rate is equal to or higher than 5.90%, the Make-Whole Amount shall be zero.

     “Reinvestment Rate” shall mean (1) the sum of 0.50%, plus the yield reported on page “USD” of the Bloomberg Financial Markets Services Screen (or, if not available, any other nationally recognized trading screen reporting on-line intraday trading in the U.S. Government Securities) at 10:00 A.M. (Chicago, Illinois time) for the U.S. Government Securities have a maturity (rounded to the nearest month) corresponding to the Remaining Life to Maturity of the principal of the Series FFF Bonds being redeemed or (2) in the event that no nationally recognized trading screen reporting on-line intraday trading in the U.S. Government Securities is available, Reinvestment Rate shall mean 0.50%, plus the arithmetic mean of the yields for the two columns under the heading “Week Ending” published in the Statistical Release under the caption “Treasury Constant Maturities” for the maturity (rounded to the nearest month) corresponding to the Remaining Life to Maturity of the principal being redeemed. If no maturity exactly corresponds to such Remaining Life to Maturity, yields for the published maturity next longer than the Remaining Life to Maturity and for the published maturity next shorter than the Remaining Life to Maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.

     “Remaining Life to Maturity” of the principal amount of the Series FFF Bonds being redeemed shall mean, as of the time of any determination thereof, the number of years (calculated to the nearest one-twelfth) which will elapse between the date of determination and the final maturity of the Series FFF Bonds being redeemed.

     “Statistical Release” shall mean the then most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Federal Reserve System and which establishes yields on actively traded U.S. Government Securities adjusted to constant maturities or, if such statistical release is not published at the time of any determination hereunder, then such other reasonably comparable index which shall be designated by the Holders holding 66-2/3% in aggregate principal amount of the Outstanding Series FFF Bonds, subject to approval of the Company which approval will not be unreasonably withheld.

     6. OPTIONAL REDEMPTION AT PAR IN EVENT OF CONDEMNATION

     In the event a Material Condemnation shall have occurred with respect to any property of the Company, then upon compliance with the notice provisions set forth in Article IV of the Base Indenture, the Company shall have the privilege of applying the proceeds of any condemnation award received in connection with such Material Condemnation to the redemption of the principal amount of the Series FFF Bonds then outstanding, or any portion thereof to the extent of such proceeds, together with accrued interest thereon to the Redemption Date. Any optional redemption made pursuant to this Section shall be without premium.

     “Condemnation” with respect to any property shall have occurred if all or any portion of such property shall have been condemned or taken for any public or quasi-public use under any governmental law, order, or regulation or by right of eminent domain or sold to a municipality or other public body or agency or any other entity having the power of eminent domain or the right to purchase or order the sale of such property (a “Condemning Authority”), or any third-party designated by any such Condemning Authority, under threat of condemnation.

     “Material Condemnation” shall mean any Condemnation of any property of the Company pursuant to which a condemnation award in excess of $100,000 shall have been received by the Company.

     7. NOTICES OF REDEMPTION

     Notices of redemption shall (except in respect of redemptions made out of cash deposited in the sinking fund described in Section 7 below) be provided in accordance with Article IV of the Base Indenture. If less than all of the Series FFF Bonds are to be redeemed at any time, the particular Series FFF Bonds to be redeemed shall be selected in accordance with Article IV of the Base Indenture. On and after the Redemption Date, interest shall cease to accrue on Series FFF Bonds or portions of them called for redemption.

     8. DENOMINATIONS; TRANSFER; EXCHANGE

     The Series FFF Bonds are in registered form without coupons in denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Series FFF Bonds in accordance with the Base Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate transfer documents and to pay any taxes required by law or permitted by the Base Indenture. The Registrar shall not be required (A) to issue, to register the transfer of or to exchange any Series FFF Bonds during a period beginning at the opening of business calendar 15 days before the day of any selection of Series FFF Bonds for redemption and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Series FFF Bond so selected for redemption in whole or in part, except the unredeemed portion of any Series FFF Bond being redeemed in part or (C) to register the transfer of or to exchange a Series FFF Bond between a Record Date and the next succeeding Interest Payment Date.

     9. PERSONS DEEMED OWNERS

     The registered Holder of this Series FFF Bond may be treated as the owner of it for all purposes.

     10. UNCLAIMED MONEY

     If money for the payment of principal or interest remains unclaimed, the Paying Agent shall pay the money back to the Company in accordance with the terms of the Base Indenture.

     11. DISCHARGE AND DEFEASANCE

     Subject to certain conditions set forth in the Base Indenture, the Company at any time may terminate some or all of its obligations under the Base Indenture and the Supplemental Indenture with respect to the Series FFF Bonds if, among other things, the Company deposits with the Trustee funds for the payment of principal and interest on the Series FFF Bonds to redemption or maturity, as the case may be.

     12. AMENDMENT, WAIVER

     The Base Indenture permits, subject to certain exceptions set forth therein, that the Base Indenture and the terms of the Bonds of a series, which include the Series FFF Bonds, and the rights of the Holders of the Bonds of a series, which may include the Holders of the Series FFF Bonds, in each case may be modified, with the written consent of the Holders of a majority in aggregate principal amount of the Bonds the terms of which or the rights of the Holders of which are to be modified. The Base Indenture also permits certain other amendments, modifications or waivers thereof only with the consent of each Outstanding Bond affected thereby, while certain other amendments or modifications may be made without the consent of any Holders of Bonds.

     The Base Indenture also provides the Holders of sixty-six and two-thirds percent (66-2/3%) or more of principal amount of the Bonds then Outstanding of all such series under which an Event of Default shall have occurred, which may include the Series FFF Bonds, may, by a written instrument or instruments signed by such Holders and delivered to the Trustee and to the Company, waive any past Default or Event of Default under such series of Bonds and its consequences except an Event of Default in the payment of the principal of, premium, if any, or interest on any of the Bonds as and when the same shall become due by the terms of such Bonds, and upon such waiver such Default or Event of Default shall be deemed not to exist for any purpose of the Base Indenture or such series of Bonds.

     Any such consent or waiver by the Holder of this Series FFF Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Series FFF Bond and of any Series FFF Bond issued in lieu of or exchange, in respect of anything done, omitted or suffered by the Trustee in pursuance thereof.

     13. DEFAULTS AND REMEDIES

     Events of Default are set forth in the Base Indenture and the Supplemental Indenture. If an Event of Default shall have occurred and be continuing, the Trustee upon the direction of Holders of not less than twenty-five percent (25%) aggregate principal amount of the Outstanding Bonds or the Holders of not less than twenty-five percent (25%) aggregate principal amount of the Outstanding Bonds, may, by notice in writing delivered to the Company (and to the Trustee if given by the Holders), declare the entire principal amount of Outstanding Bonds, premium, if any, and the interest accrued thereon immediately due and payable, and said entire principal, premium, if any, and interest shall thereupon become and be immediately due and payable.

     Upon the acceleration of the Series FFF Bonds pursuant to Section 7.01 of the Base Indenture, such Series FFF Bonds shall forthwith mature and the entire unpaid principal amount of such Bonds, plus all accrued and unpaid interest thereon and the Make-Whole Amount determined in respect of the Called Principal (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each Holder of a Series FFF Bond has the right to maintain its investment in the Series FFF Bonds free from repayment by the Company (except as specifically provided for by the terms of the Series FFF Bonds), and that the provision for payment of a Make-Whole Amount by the Company in the event that the Series FFF Bonds are prepaid or accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

     Holders may not enforce the Base Indenture, the Supplemental Indenture or the Series FFF Bonds except as provided in the Base Indenture. The Trustee may refuse to enforce the Base Indenture, the Supplemental Indenture or the Series FFF Bonds unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Outstanding Bonds may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any Default (except a Default in payment of principal or interest on any Bond, or in the payment of any sinking fund installment) if and so long as Responsible Officers of the Trustee in good faith determine that withholding notice is in the interest of the Holders.

     14. TRUSTEE DEALINGS WITH THE COMPANY

     Subject to certain limitations imposed by the TIA, the Trustee, in its individual or any other capacity, may become the owner or pledgee of the Series FFF Bonds and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

     15. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     No director, officer, employee, incorporator or stockholder of the Company or Parent shall have any liability for any obligations of the Company under the Base Indenture, the Supplemental Indenture or the Series FFF Bonds or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting the Series FFF Bonds waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Series FFF Bonds. Such waiver may not be effective to waive liabilities of directors, officers or persons controlling the Company under the federal securities laws and it is the view of the Commission that such waiver is against public policy and is therefore unenforceable.

     16. GOVERNING LAW

     The Series FFF Bonds shall be governed by, and construed and enforced in accordance with, the laws of the State of California without regard to the principles of conflicts of laws thereunder, except to the extent that the TIA shall be applicable.

     17. AUTHENTICATION

     This Series FFF Bond shall not be valid until an authorized signatory of the Trustee (or an Authenticating Agent) manually signs the certificate of authentication on the other side of this Series FFF Bond.

     18. ABBREVIATIONS

     Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

     19. SECURITY INTEREST

     The Series FFF Bonds shall be secured to the extent and in the manner provided by the Base Indenture.

     The Company shall furnish to any Holder upon written request and without charge to the Holder a copy of the Base Indenture and the Supplemental Indenture. Requests may be made to:
