USE OF PROCEEDS

The net proceeds from the sale of the Series MM bonds will become part of our general treasury funds and will be used to repay $250 million of First Mortgage Bonds maturing in January 2011 and replenish amounts expended and to be expended for the expansion and improvement of our utility plant. We estimate that the expenses for this offering, excluding underwriting discounts, will be approximately $250,000.

RATIO OF EARNINGS TO FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

The following table sets forth the ratio of our earnings to fixed charges and the ratio of our earnings to combined fixed charges and preferred dividends for each of the years in the five-year period ended December 31, 2009 and for the nine months ended September 30, 2010:


	Nine Months Ended September 30, 2010		Years Ended December 31,
	Nine Months Ended September 30, 2010		2009		2008		2007		2006		2005
Ratio of Earnings to Fixed Charges		7.27		6.56		6.75		6.20		6.21		6.83
Ratio of Earnings to Combined Fixed Charges and Preferred Stock Dividends		7.02		6.39		6.55		6.04		6.05		6.58

We determine the ratio of earnings to fixed charges by dividing (a) the sum of pretax income from continuing operations (less capitalized interest) and fixed charges by (b) fixed charges consisting of all interest expense (before allowances for borrowed funds used during construction), a portion of rent expenses which approximates the interest component of such expense, and amortization of debt issuance costs.

We determine the ratio of earnings to combined fixed charges and preferred stock dividends by dividing (a) the sum of pretax income from continuing operations (less capitalized interest), fixed charges and preferred stock dividends by (b) the sum of (i) fixed charges consisting of all interest expense (before allowances for borrowed funds used during construction), a portion of rent expenses which approximates the interest component of such expense, and amortization of debt issuance costs and (ii) preferred stock dividends.

SUPPLEMENTAL DESCRIPTION OF FIRST MORTGAGE BONDS

The Series MM bonds offered by this prospectus supplement are a series of our first mortgage bonds as described below and in the accompanying prospectus. The Series MM bonds will be issued under a supplemental indenture and the applicable indenture referred to in the accompanying prospectus, each between us, as issuer, and U.S. Bank National Association, as trustee. We have summarized below selected provisions of the supplemental indenture applicable to the Series MM bonds. The summary of the provisions of our first mortgage bonds contained in the accompanying prospectus applies to the provisions of the Series MM bonds, except that the summary of selected provisions of the Series MM bonds and the supplemental indenture set forth below supplements and, to the extent inconsistent, supersedes and replaces the description of the general terms and provisions of our first mortgage bonds and the indenture contained in the accompanying prospectus. This summary is not complete and is qualified by reference to provisions of the Series MM bonds, the supplemental indenture and the indenture. Terms used in this section but not defined have the meanings given to those terms in the accompanying prospectus or, if not defined in the accompanying prospectus, in the supplemental indenture or the indenture. As used in this section and under the caption “Description of First Mortgage Bonds” in the accompanying prospectus, references to “we,” “our,” “us,” and “SCGC” mean Southern California Gas Company excluding its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

General

The Series MM bonds will constitute a series of first mortgage bonds under the indenture, initially limited to $300 million aggregate principal amount.

The Series MM bonds will mature on November 15, 2040. The Series MM bonds will bear interest at the rate of 5.125% per annum, accruing from November 18, 2010. Interest on the Series MM bonds will be payable semiannually in arrears on May 15 and November 15 of each year, commencing May 15, 2011, to the persons in whose names the Series MM bonds are registered at the close of business on the May 1 or November 1, as the case may be, next preceding those interest payment dates. Interest on the Series MM bonds will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

The Series MM bonds will be redeemable prior to maturity, at our option, at the prices and circumstances set forth below under the caption “Optional Redemption.” The Series MM bonds will not be subject to a sinking fund.

At September 30, 2010, we had outstanding $1,250 million of first mortgage bonds and the net book value of the property subject to the first lien of the indenture was $3.7 billion. For the twelve months ended September 30, 2010 and without giving effect to the issuance of the Series MM bonds, the Net Earnings of the Corporation Available for Interest (as defined in the indenture) were 12.6 times the interest charges on our bonds outstanding under the indenture.

Optional Redemption

We may redeem all or any part of the Series MM bonds, at our option at any time or from time to time, at the prices set forth in this paragraph. The redemption price for the Series MM bonds to be redeemed on any redemption date will be equal to the greater of the following amounts:

•

100% of the principal amount of the Series MM bonds being redeemed on the redemption date; or

•

the sum of the present values of the remaining scheduled payments of principal and interest on the Series MM bonds being redeemed on that redemption date (not including any portion of any payments of accrued and unpaid interest to the redemption date) discounted to the redemption date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 15 basis points, as determined by the Independent Investment Banker (as defined below),

plus, in each case, accrued and unpaid interest thereon to the redemption date. Notwithstanding the foregoing, installments of interest on Series MM bonds that are due and payable on interest payment dates falling on or

S-3

prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record dates according to the Series MM bonds and the indenture. The redemption price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each registered holder of the Series MM bonds to be redeemed. Once notice of redemption is mailed, the Series MM bonds called for redemption will become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest to the redemption date. Redemption will not be conditional upon receipt by the trustee of monies sufficient to pay the redemption price.

Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Series MM, bonds or portions thereof called for redemption. We will pay the redemption price and any accrued interest once the Series MM bonds are surrendered for redemption. If only a portion of the Series MM bonds are redeemed, the trustee will deliver new Series MM bonds for the remaining portion without charge.

“Adjusted Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semiannual 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 such redemption date.

“Comparable Treasury Issue” means, with respect to any redemption date, the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Series MM bonds to be redeemed on such redemption date 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 such Series MM bonds.

“Comparable Treasury Price” means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer Quotations for such redemption date, or (B) if only one Reference Treasury Dealer Quotation is received, such Quotation.

“Independent Investment Banker” means, with respect to any redemption date, one of the Reference Treasury Dealers appointed by us to act as the “Independent Investment Banker.”

“Reference Treasury Dealer” means, with respect to any redemption date, (A) Goldman, Sachs & Co. and RBS Securities Inc. (or their respective affiliates which are Primary Treasury Dealers) and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by us.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by us, 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 us by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third business day preceding such redemption date.

In the event that we elect to redeem only a portion of the Series MM bonds, the bonds to be redeemed shall be selected in accordance with the procedures of The Depository Trust Company, in the case of bonds represented by a global security, or by the trustee by a method the trustee deems to be fair and appropriate, in the case of bonds that are not represented by a global security.

Notice Regarding Remedies with Respect to Mortgaged Property

Any foreclosure on the mortgaged property by the trustee may be limited by applicable California law. Section 726 of the California Code of Civil Procedure provides that any action to recover on a debt or other right secured by a mortgage or a deed of trust on real property or an estate for years therein must comply with the provisions of that section, which provisions relate to and specify the procedures for the sale of encumbered property or an estate for years therein, the application of proceeds, the rendition in certain cases of a deficiency

S-4

judgment, and other related matters. We advise you that in such an action or proceeding, the debtor may require the creditor to exhaust all of its security before a personal judgment may be obtained against the debtor for a deficiency. We also advise you that failure to comply with the provisions of Section 726 may result in the extinguishment of the liens on the mortgaged property and the loss of your right to a deficiency judgment. Section 580d of the California Code of Civil Procedure provides that no deficiency judgment shall be rendered on a note secured by a deed of trust or mortgage on real property after sale of the real property under the power of sale contained in such deed of trust or mortgage.

Defeasance

The defeasance provisions of the indenture will apply to the Series MM bonds. However, with respect to the satisfaction of the indenture following the release of the mortgaged property (but not as a condition to the release of the mortgaged property), in addition to the conditions of defeasance specified in the indenture we will be required to deliver an opinion of counsel to the effect that a holder of Series MM bonds will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amounts, at the same times and in the same manner as if that defeasance had not occurred. The opinion of counsel must be based upon a ruling of the Internal Revenue Service or a change in law after November 15, 2010.

Other

We may, from time to time, without notice to or the consent of the holders of the Series MM bonds, increase the principal amount of this series of first mortgage bonds under the indenture and issue such increased principal amount (or any portion thereof). Any additional Series MM bonds so issued shall have the same form and terms (other than the offering price, the date of issuance and, under certain circumstances, the date from which interest thereon shall begin to accrue and the first interest payment date) as the Series MM bonds previously issued and shall form a single series with the Series MM bonds.

The Series MM bonds initially will be issued in book-entry form and represented by one or more global securities deposited with, or on behalf of, The Depository Trust Company, as Depositary, and registered in the name of Cede & Co., its nominee. This means that you will not be entitled to receive a certificate for the Series MM bonds that you purchase except under the limited circumstances described under the caption “Global Securities” of the accompanying prospectus.

S-5

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting agreement, the underwriters named below have agreed, severally and not jointly, to purchase, and we have agreed to sell to them, severally and not jointly, the respective principal amount of the Series MM bonds set forth opposite their respective names below.


Underwriter	Principal Amount of Series MM Bonds
Goldman, Sachs & Co.	$	75,000,000
Mitsubishi UFJ Securities (USA), Inc.		75,000,000
Samuel A. Ramirez & Company, Inc.		37,500,000
RBS Securities Inc.		75,000,000
The Williams Capital Group, L.P.		37,500,000

Total	$	300,000,000

The underwriting agreement provides that the obligation of the several underwriters to pay for and accept delivery of the Series MM bonds is subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all the Series MM bonds if any are taken.

We have been advised by the underwriters that the underwriters propose to offer the Series MM bonds to the public initially at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of 0.50% of the principal amount per Series MM bond. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.25% of the principal amount of the Series MM bonds on sales to certain other dealers. After the initial public offering, the price to investors and concessions may be changed.

The Series MM bonds are a new issue of securities with no established trading market. There can be no assurance of a secondary market for the Series MM bonds or the continued liquidity of such market if one develops. The underwriters have informed us that they intend to make a market in the Series MM bonds but are under no obligation to do so and such market making may he terminated at any time without notice.

In order to facilitate the offering of the Series MM bonds, the underwriters, or any of their affiliates, may engage in transactions that stabilize, maintain or otherwise affect the price of the Series MM bonds. Specifically, the underwriters may overallot in connection with the offering, creating a short position in the Series MM bonds for their own account. In addition, to cover overallotments or to stabilize the price of the Series MM bonds, the underwriters may bid for, and purchase, the Series MM bonds in the open market. The underwriters may reclaim selling concessions allowed to an underwriter or dealer for distributing the Series MM bonds in the offering if the underwriters repurchase previously distributed Series MM, bonds in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the Series MM bonds above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased Series MM bonds sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the Series MM bonds. As a result, the price of the Series MM bonds may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

S-6

Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that any of the transactions described above may have on the price of the Series MM bonds. In addition, neither we nor any of the underwriters makes any representation that the transactions will be engaged in or that the transactions, once commenced, will not he discontinued without notice.

Certain of the underwriters and their affiliates have in the past and may in the future engage in transactions with us, and/or perform services, including investment banking, advisory and general financing and commercial banking services, for us in the ordinary course of business for which they may receive customary fees and expenses.

We have agreed to indemnify the several underwriters against certain liabilities, including civil liabilities under the Securities Act of 1933, as amended, or contribute to payments which the underwriters may be required to make in respect thereof.

Expenses payable by us in connection with the offering of the Series MM bonds, excluding underwriting discounts, are estimated at $250,000.

S-7

LEGAL MATTERS

Gary W. Kyle, Chief Corporate Counsel of Sempra Energy, our ultimate parent company, will pass upon the validity of the Series MM bonds and various other legal matters relating to the issuance and sale of the Series MM bonds. Latham & Watkins LLP will pass upon certain legal matters relating to the issuance and sale of the Series MM bonds on our behalf. Sidley Austin LLP, San Francisco, California, will act as counsel for the underwriters. Paul Pringle is a partner of Sidley Austin LLP and owns 3,824 shares of common stock of Sempra Energy.

DESCRIPTION OF SENIOR DEBT SECURITIES

Unless indicated differently in a prospectus supplement, the following is a general description of the terms and provisions of the senior debt securities we may offer and sell by this prospectus. In this section, references to “indenture” mean the senior debt indenture.

The senior debt securities will be governed by the indenture. The indenture gives us broad authority to set the particular terms of each series of senior debt securities, including the right to modify certain of the terms contained in the indenture. The particular terms of a series of senior debt securities and the extent, if any, to which the particular terms of the issue modify the terms of the indenture will be described in the prospectus supplement relating to such series of senior debt securities.

The indenture contains the full legal text of the matters described in this section. Because this section is a summary, it does not describe every aspect of the senior debt securities or the indenture. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture, including definitions of terms used in the indenture. We also include references in parentheses to particular sections of the indenture. Whenever we refer to particular sections or defined terms of the indenture in this prospectus or in a prospectus supplement, the sections or defined terms are incorporated by reference into this prospectus or into the prospectus supplement. This summary also is subject to and qualified by reference to the description of the terms of a particular series of senior debt securities described in the applicable prospectus supplement.

General

We may issue an unlimited amount of senior debt securities under the indenture in one or more series. We are not required to issue all senior debt securities of one series at the same time and, unless otherwise provided in a prospectus supplement, we may reopen a series, without the consent of the holders of the senior debt securities of that series, for issuances of additional senior debt securities of that series. The senior debt securities will be our unsecured obligations.

Prior to the issuance of each series of senior debt securities, the terms of the particular securities will be specified in either a supplemental indenture or a board resolution and one or more officers’ certificates. We refer you to the applicable prospectus supplement for a description of the following terms of each series of senior debt securities:

•

the title of the senior debt securities;

•

any limit upon the aggregate principal amount of the senior debt securities;

•

the date or dates on which principal will be payable or the method of determining such date or dates;

•

the rate or rates or method of determination of interest; the date or dates from which interest will accrue; the dates on which interest will be payable, which we refer to as the “interest payment dates”; the manner (if any) of determination of such interest payment dates; and any record dates for the interest payable on the interest payment dates;

•

any obligation or option we have to redeem or purchase senior debt securities, or any option of the registered holder to require us to redeem or repurchase senior debt securities, and the terms and conditions upon which the senior debt securities will be redeemed or purchased;

•

the denominations in which the senior debt securities will be issuable, if other than denominations of $1,000 and any integral multiple thereof;

•

whether the senior debt securities are to be issued in whole or in part in the form of one or more global debt securities and, if so, the identity of the depositary for the global debt securities; and

•

any other terms of the senior debt securities that may be different from those described below.

(See Section 301.)

Ranking

The senior debt securities will be our unsecured and unsubordinated obligations. The indebtedness represented by the senior debt securities will rank equally with all our other unsecured and unsubordinated debt. The senior debt securities are our obligations exclusively, and are not the obligations of our subsidiaries or our parent. Although the senior debt securities will be our senior unsubordinated obligations, the outstanding first mortgage bonds will have a claim to the assets securing the first mortgage bonds prior to any claim by holders of the senior debt securities.

Payment of Senior Debt Securities—Interest

We will pay interest on the senior debt securities on each interest payment date by check mailed to the person in whose name the senior debt securities are registered as of the close of business on the regular record date relating to the interest payment date.

However, if we default in paying interest on a senior debt security, we will pay defaulted interest in either of the two following ways:

•

We will first propose to the trustee a payment date for the defaulted interest. Next, the trustee will choose a special record date for determining which registered holders are entitled to the payment. The special record date will be from 10 to 15 days before the proposed payment date. Finally, we will pay the defaulted interest on the payment date to the registered holder of the senior debt securities as of the close of business on the special record date.

•

Alternatively, we can propose to the trustee any other lawful manner of payment that is consistent with the requirements of any securities exchange on which the senior debt securities are listed for trading. If the trustee thinks the proposal is practicable, payment will be made as proposed.

(See Section 307.)

Payment of Senior Debt Securities—Principal

We will pay principal of and any premium on the senior debt securities at stated maturity, upon redemption or otherwise, upon presentation of the senior debt securities at the office of the trustee, as paying agent. Any other paying agent initially designated for the senior debt securities of a particular series will be named in the applicable prospectus supplement. In our discretion, we may appoint one or more additional paying agents and security registrars and designate one or more additional places for payment and for registration of transfer. Unless otherwise specified in the applicable prospectus supplement, a place for payment and registration of transfer of the senior debt securities will be provided in the Borough of Manhattan, the City of New York, New York. (See Section 1002.)

If any interest payment date, redemption date or the maturity date of the senior debt securities is not a business day at any place of payment, then payment of the principal, premium, if any, and interest may be made on the next business day at that place of payment. In that case, no interest will accrue on the amount payable for the period from and after the applicable interest payment date, redemption date or maturity date, as the case may be.

Form; Transfers; Exchanges

The senior debt securities initially will be issued in book-entry form and represented by one or more global securities deposited with, or on behalf of, The Depository Trust Company, as depositary, and registered in the name of Cede & Co., its nominee. This means that you will not be entitled to receive a certificate for the senior

debt securities that you purchase except under the limited circumstances described below under the caption “Global Securities.” If any of the senior debt securities are issued in certificated form they will be issued only in fully registered form without coupons, in denominations of $1,000 and integral multiples of $1,000.

So long as the senior debt securities are in book-entry form, you will receive payments and may transfer senior debt securities only through the facilities of DTC and its direct and indirect participants as described below under the caption “Global Securities.” We will maintain an office or agency in the Borough of Manhattan, The City of New York where notices and demands in respect of the senior debt securities and the indenture may be delivered to us and where certificated senior debt securities including the senior debt securities may be surrendered for payment, registration of transfer or exchange. That office or agency will initially be an office of the trustee, which is currently located at 100 Wall Street, Suite 1600, New York, New York 10005.

You may have your senior debt securities divided into senior debt securities of smaller authorized denominations, or combined into senior debt securities of larger authorized denominations, as long as the total principal amount is not changed. This is called an “exchange.” (See Section 305.)

You may exchange or transfer senior debt securities at the office of the trustee. The trustee acts as our agent for registering senior debt securities in the names of holders and transferring senior debt securities. We may appoint another agent or act as our own agent for this purpose. The entity performing the role of maintaining the list of registered holders is called the “security registrar.” It will also perform transfers. (See Section 305.)

In our discretion, we may change the place for registration of transfer of the senior debt securities and may remove and/or appoint one or more additional security registrars. (See Sections 305 and 1002.)

Except as otherwise provided in a prospectus supplement, there will be no service charge for any transfer or exchange of the senior debt securities, but you may be required to pay a sum sufficient to cover any tax or other governmental charge payable by us in connection with the transfer or exchange. We may block the transfer or exchange of (a) senior debt securities during a period of 15 days prior to giving any notice of redemption or (b) any senior debt security selected for redemption in whole or in part, except the unredeemed portion of any senior debt security being redeemed in part. (See Section 305.)

Optional Redemption

The redemption provisions, if any, applicable to the senior debt securities will be set forth in the applicable prospectus supplement.

We will mail notice of any redemption at least 30 days, but not more than 60 days, before the redemption date to each registered holder of the senior debt securities to be redeemed. Once notice of redemption is mailed, the senior debt securities called for redemption will become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest to the redemption date. If we elect to redeem all or a portion of the senior debt securities, that redemption will not be conditional upon receipt by the paying agent or the trustee of monies sufficient to pay the redemption price. (See Section 1104.)

Senior debt securities will cease to bear interest on the redemption date. We will pay the redemption price and any accrued interest once the senior debt securities are surrendered for redemption. (See Section 1105.) If only part of a senior debt security is redeemed, the trustee will deliver new senior debt securities of the same series for the remaining portion without charge. (See Section 1106.) Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the senior debt securities or portions thereof called for redemption.

In the event that we elect to redeem only a portion of the senior debt securities, the senior debt securities to be redeemed will be selected in accordance with the procedures of The Depository Trust Company, in the case of senior debt securities represented by a global security, or by the trustee by a method the trustee deems to be fair and appropriate, in the case of senior debt securities that are not represented by a global security.

Events of Default

An “event of default” occurs with respect to the senior debt securities of any series if:

•

we do not pay any interest on any senior debt securities of the applicable series within 30 days of the due date;

•

we do not pay any principal of or premium on any senior debt securities of the applicable series on the due date;

•

we remain in breach of a covenant or warranty (excluding covenants and warranties solely applicable to another series of debt securities issued under the indenture) in the indenture or the senior debt securities of the applicable series for 60 days after we receive a written notice of default stating we are in breach and requiring remedy of the breach; the notice must be sent by either the trustee or registered holders of at least 25% of the principal amount of the outstanding senior debt securities of the affected series;

•

default occurs under any bond, note, debenture or other instrument evidencing any indebtedness for money borrowed by us, excluding our subsidiaries (including a default with respect to any other series of senior debt securities issued under the indenture), or under any mortgage, indenture or other instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by us, or the payment of which is guaranteed by us, whether such indebtedness or guarantee exists on the date of the indenture or is issued or entered into following the date of the indenture, if:

(A)

either:

(i)

such default results from the failure to pay any such indebtedness when due; or

(ii)

as a result of such default the maturity of such indebtedness has been accelerated prior to its expressed maturity; and

(B)

the principal amount of such indebtedness, together with the principal amount of any other such indebtedness in default for failure to pay any such indebtedness when due or the maturity of which has been so accelerated, aggregates at least $25 million;

•

we file for bankruptcy or other specified events in bankruptcy, insolvency, receivership or reorganization occur; or

•

any other event of default specified in the prospectus supplement for such series occurs.

(See Section 501.)

No event of default with respect to a series of senior debt securities necessarily constitutes an event of default with respect to the senior debt securities of any other series issued under the indenture.

Remedies

Acceleration

If an event of default occurs and is continuing with respect to any series of senior debt securities, then either the trustee or the registered holders of at least 25% in principal amount of the outstanding senior debt securities of that series may declare the principal amount of all of the senior debt securities of that series, together with accrued and unpaid interest thereon, to be due and payable immediately. (See Section 502.)

Rescission of Acceleration

After the declaration of acceleration has been made with respect to any series of senior debt securities and before the trustee has obtained a judgment or decree for payment of the money due, the declaration and its consequences will be rescinded and annulled, if:

(a) we pay or deposit with the trustee a sum sufficient to pay:

•

all overdue interest on the senior debt securities of that series, other than interest which has become due by declaration of acceleration;

•

the principal of and any premium on the senior debt securities of that series which have become due, otherwise than by the declaration of acceleration, and overdue interest on these amounts;

•

interest on overdue interest, other than interest which has become due by declaration of acceleration, on the senior debt securities of that series to the extent lawful;

•

all amounts due to the trustee under the indenture; and

(b) all events of default with respect to the senior debt securities of that series, other than the nonpayment of the principal and interest which has become due solely by the declaration of acceleration, have been cured or waived as provided in the indenture.

(See Section 502.)

For more information as to waiver of defaults, see “Waiver of Default and of Compliance” below.

Control by Registered Holders; Limitations

If an event of default with respect to the senior debt securities of any series occurs and is continuing, the registered holders of a majority in principal amount of the outstanding senior debt securities of that series, voting as a single class, without regard to the holders of outstanding senior debt securities of any other series that may also be in default, will have the right to direct the time, method and place of:

•

conducting any proceeding for any remedy available to the trustee with respect to the senior debt securities of that series; and

•

exercising any trust or power conferred on the trustee with respect to the senior debt securities of that series.

These rights of registered holders to give directions are subject to the following limitations:

•

the registered holders’ directions do not conflict with any law or the indenture; and

•

the direction is not unduly prejudicial to the rights of holders of the senior debt securities of that series who do not join in that action.

The trustee may also take any other action it deems proper which is consistent with the registered holders’ direction. (See Sections 512 and 603.)

In addition, the indenture provides that no registered holder of senior debt securities of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or for any other remedy under the indenture unless:

•

that registered holder has previously given the trustee written notice of a continuing event of default;

•

the registered holders of at least 25% in aggregate principal amount of the outstanding senior debt securities of that series have made written request to the trustee to institute proceedings in respect of that event of default and have offered the trustee reasonable indemnity against costs and liabilities incurred in complying with the request; and

•

for 60 days after receipt of the notice, the trustee has failed to institute a proceeding and no direction inconsistent with the request has been given to the trustee during the 60-day period by the registered holders of a majority in aggregate principal amount of outstanding senior debt securities of that series.

Furthermore, no registered holder will be entitled to institute any action if and to the extent that the action would disturb or prejudice the rights of other registered holders of senior debt securities. (See Section 507.)

However, each registered holder has an absolute and unconditional right to receive payment when due and to bring a suit to enforce that right. (See Section 508.)

Notice of Default

The trustee is required to give the registered holders of senior debt securities of the affected series notice of any default under the indenture to the extent required by the Trust Indenture Act; except that in the case of an event of default of the character specified above in the third bullet under the caption “Events of Default,” no notice will be given to such registered holders until at least 30 days after the occurrence of the default. The Trust Indenture Act currently permits the trustee to withhold notices of default (except for certain payment defaults) if the trustee in good faith determines the withholding of the notice to be in the interests of the registered holders. (See Section 602.)

We will furnish the trustee with an annual statement as to our compliance with the conditions and covenants in the indenture. (See Section 1005.)

Waiver of Default and of Compliance

The registered holders of a majority in aggregate principal amount of the outstanding senior debt securities of any series, voting as a single class, without regard to the holders of outstanding senior debt securities of any other series, may waive, on behalf of all registered holders of the senior debt securities of that series, any past default under the indenture, except a default in the payment of principal, premium or interest, or with respect to compliance with certain provisions of the indenture that cannot be amended without the consent of the registered holder of each outstanding senior debt security of that series. (See Section 513.)

Compliance with certain covenants in the indenture or otherwise provided with respect to senior debt securities of any series may be waived by the registered holders of a majority in aggregate principal amount of the senior debt securities of that series. (See Section 1006.)

Consolidation, Merger and Conveyance of Assets as an Entirety; No Financial Covenants

We have agreed not to consolidate or merge with or into any other entity, or to sell, transfer, lease or otherwise convey any of our property and assets as an entirety or substantially as an entirety to any entity, unless:

•

we are the continuing entity (in the case of a merger) or the successor entity formed by such consolidation or into which we are merged or which acquires by sale, transfer, lease or other conveyance our property and assets, as an entirety or substantially as an entirety, is a corporation organized and existing under the laws of the United States of America or any state thereof or the District of Columbia, and expressly assumes, by supplemental indenture, the due and punctual payment of the principal, premium and interest on all the senior debt securities and the performance of all of the covenants under the indenture; and

•

immediately after giving effect to the transaction, no event of default, and no event which after notice or lapse of time or both would become an event of default, has or will have occurred and be continuing.

The indenture does not contain any financial or other similar restrictive covenants.

(See Section 801.)

Modification of Indenture

Without Registered Holder Consent

Without the consent of any registered holders of senior debt securities, we and the trustee may enter into one or more supplemental indentures for any of the following purposes:

•

to evidence the succession of another entity to us; or

•

to add one or more covenants for the benefit of the holders of all or any series of senior debt securities or to surrender any right or power conferred upon us; or

•

to add any additional events of default for all or any series of senior debt securities; or to change or eliminate any provision of the indenture so long as the change or elimination does not apply to any senior debt securities entitled to the benefit of such provision; or to add any new provision to the indenture, in addition to the provisions which may otherwise be added to the indenture pursuant to the other clauses of this paragraph, so long as the addition does not apply to any outstanding senior debt securities; or

•

to provide security for the senior debt securities of any series; or

•

to establish the form or terms of senior debt securities of any series, as permitted by the indenture; or

•

to evidence and provide for the acceptance of appointment of a separate or successor trustee; or

•

to cure any ambiguity, defect or inconsistency or to make any other changes with respect to any series of senior debt securities that do not adversely affect the interests of the holders of senior debt securities of that series in any material respect.

(See Section 901.)

With Registered Holder Consent

Subject to the following sentence, we and the trustee may, with some exceptions, amend or modify the indenture with the consent of the registered holders of at least a majority in aggregate principal amount of the senior debt securities of each series affected by the amendment or modification. However, no amendment or modification may, without the consent of the registered holder of each outstanding senior debt security affected thereby:

•

change the stated maturity of the principal or interest on any senior debt security or reduce the principal amount, interest or premium payable or change any place of payment where or the currency in which any senior debt security is payable, or impair the right to bring suit to enforce any payment;

•

reduce the percentages of registered holders whose consent is required for any supplemental indenture or waiver; or

•

modify certain of the provisions in the indenture relating to supplemental indentures and waivers of certain covenants and past defaults.

A supplemental indenture which changes or eliminates any provision of the indenture expressly included solely for the benefit of holders of senior debt securities of one or more particular series will be deemed not to affect the interests under the indenture of the holders of senior debt securities of any other series.

(See Section 902.)

Defeasance

The indenture provides, unless the terms of the particular series of senior debt securities provide otherwise, that we may, upon satisfying several conditions, be discharged from our obligations, with some exceptions, with respect to any series of senior debt securities, which we refer to as “defeasance.”

One condition we must satisfy is the irrevocable deposit with the trustee, in trust, of money and/or government obligations which, through the scheduled payment of principal and interest on those obligations, would provide sufficient funds to pay the principal of and any premium and interest on those senior debt securities on the maturity dates of the payments or upon redemption.

In addition, we will be required to deliver an opinion of counsel to the effect that a holder of senior debt securities will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amounts, at the same times and in the same manner as if that defeasance had not occurred. The opinion of counsel must be based upon a ruling of the Internal Revenue Service or a change in law after the date of the indenture.

(See Article XIII.)

Satisfaction and Discharge

The indenture will cease to be of further effect with respect to any series of senior debt securities, and we will be deemed to have satisfied and discharged all of our obligations under the indenture, except as noted below, when:

•

all outstanding senior debt securities of such series have become due or will become due within one year at their stated maturity or on a redemption date; and

•

we deposit with the trustee, in trust, funds that are sufficient to pay and discharge all remaining indebtedness on the outstanding senior debt securities of such series.

We will remain obligated to pay all other amounts due under the indenture and to perform certain ministerial tasks as described in the indenture.

(See Section 401.)

Resignation and Removal of the Trustee; Deemed Resignation

The trustee with respect to any series of senior debt securities may resign at any time by giving us written notice. The trustee may also be removed with respect to the senior debt securities of any series by act of the registered holders of a majority in principal amount of the then outstanding senior debt securities of such series. No resignation or removal of the trustee and no appointment of a successor trustee will become effective until the acceptance of appointment by a successor trustee in accordance with the requirements of the indenture. Under certain circumstances, we may appoint a successor trustee with respect to such series and if the successor trustee accepts, the trustee will be deemed to have resigned. (See Section 610.)

Miscellaneous Provisions

The indenture provides that certain senior debt securities, including those for which payment or redemption money has been deposited or set aside in trust as described under the caption “Satisfaction and Discharge” above, will not be deemed to be “outstanding” in determining whether the registered holders of the requisite principal amount of the outstanding senior debt securities have given or taken any demand, direction, consent or other action under the indenture as of any date, or are present at a meeting of registered holders for quorum purposes. (See Section 101.)

We will be entitled to set any day as a record date for the purpose of determining the registered holders of outstanding senior debt securities of any series entitled to give or take any demand, direction, consent or other action under the indenture, in the manner and subject to the limitations provided in the indenture. In certain circumstances, the trustee also will be entitled to set a record date for action by registered holders of any series. If a record date is set for any action to be taken by registered holders of particular senior debt securities, the action may be taken only by persons who are registered holders of the respective senior debt securities on the record date. (See Section 104.)

Governing Law

The indenture and the related senior debt securities will be governed by and construed in accordance with the laws of the State of New York. (See Section 112.)

DESCRIPTION OF FIRST MORTGAGE BONDS

Unless indicated differently in a prospectus supplement, the following is a general description of the terms and provisions of the bonds we may offer and sell with this prospectus. The summary is not meant to be a complete description. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for each series of bonds. The accompanying prospectus supplement may add, update or change the terms and conditions of a particular series of bonds from the terms and conditions described in this prospectus. In this section, references to “indenture” mean the mortgage indenture.

The indenture gives us authority to set the particular terms of each series of bonds as described in the indenture. Under the indenture, we may decide whether the bonds of a particular series will be redeemable, convertible into shares of stock, bonds, notes or other obligations, issuable as coupon bonds, fully registered bonds without coupons or, if provided in a supplemental indenture, as global securities, and whether the bonds are entitled to the benefits of any purchase, sinking, improvement, renewal or trust fund. For more information about the bonds offered by us, please refer to the indenture between us and U.S. Bank National Association, as trustee, together with the applicable supplemental indentures (as so supplemented, the “indenture”). The indenture is filed as an exhibit to the registration statement.

The indenture is subject to and governed by the Trust Indenture Act of 1939, as amended, and may be supplemented or amended from time to time. The indenture contains the full legal text of the matters described in this section. Because this section is a summary, it does not describe every aspect of the bonds or the indenture. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture, including definitions of terms used in the indenture. The parenthetical section references in the following description refer to particular sections of the indenture. Capitalized defined terms used in this description have the meanings given to them in the indenture. Whenever we refer to particular sections or defined terms of the indenture in this prospectus or in a prospectus supplement, these sections or defined terms are incorporated by reference into this prospectus or in a prospectus supplement. This summary also is subject to and qualified by reference to the description of the terms of a particular series of bonds described in the applicable prospectus supplement.

General

We may issue bonds under the indenture in one or more series, subject to the limitations described below under the caption “Issuance of Additional Bonds.” Bonds may be issued in denominations of $1,000, $5,000, $10,000, $25,000 or integral multiples of $25,000. Unless specified otherwise in the applicable prospectus supplement, the bonds will be issued in book-entry form as described under the caption “Global Securities” in this prospectus. Bonds will be payable, exchangeable for bonds of other authorized denominations and transferable at the principal office of the trustee, in San Francisco, California and each place designated for payment, including the Borough of Manhattan, City of New York, New York. (Section 2.01)

Prior to the issuance of each series of bonds, the terms and conditions of the particular series of bonds will be determined by our Board of Directors or a committee of directors and specified in a supplemental indenture. We refer you to the applicable prospectus supplement for a description of the following terms of each series of bonds:

•

the title or designation of the bonds;

•

the aggregate principal amount of the bonds in such series;

•

the date or dates on which principal will be payable or how to determine the dates;

•

the rate or rates or method of determining interest, the date from which interest will accrue, the dates on which interest will be payable, which we refer to as the “interest payment dates,” and any record dates for the interest payable on the interest payment dates;

•

whether we will have any obligation or option to redeem, purchase or repay bonds of such series prior to their maturity and the terms and conditions upon which the bonds may be redeemed, purchased or repaid;

•

whether the bonds will be entitled to the benefits of any purchase, sinking, improvement, renewal or trust fund;

•

whether the bonds will be convertible into shares of stock, bonds, notes or other obligations and/or have warrants providing for the purchase of shares of stock, bonds, notes or other obligations;

•

whether the bonds will be issuable as coupon bonds, fully registered bonds without coupons or, if provided in a supplemental indenture, as global securities; and

•

any other terms and conditions of the bonds that may supplement those described below. (See Section 2.01.)

Issuance of Additional Bonds

Additional bonds secured by the indenture may be issued in a maximum aggregate principal amount equal to the sum of:

•

66²/3% of the Net Bondable Value of Property Additions that have not been applied to other indenture purposes; (See Section 4.04.)

•

100% of the amount of cash deposited with the trustee for the purpose of issuing additional bonds; (See Section 4.05.) and

•

100% of the aggregate principal amount of Refundable Bonds, which include bonds that have been retired by payment at maturity, redemption or purchase (other than through sinking fund payments or other funds deposited with the trustee as Mortgaged Property) and not applied to other indenture purposes. (See Section 4.06.)

However, the aggregate principal amount of bonds that we can issue under the indenture may not exceed 50% of our Net Investment in Mortgaged Property, after giving effect to the issuance of such additional bonds. (See Section 4.01.) In addition, no additional bonds may be issued under the indenture (except under certain circumstances relating to those issued on the basis of Refundable Bonds) unless the Net Earnings of the Corporation Available for Interest for any 12 consecutive months in the past 15 months equals at least twice our interest charges on the sum of (i) all the bonds outstanding under the indenture, including such additional bonds, (ii) in the event of a consolidation, merger or transfer of assets, the indebtedness of any successor corporation maturing more than one year from the date of its issuance, but only if such successor corporation does not secure the bonds with a lien on all of its property, other than Excepted Property, and (iii) all of our indebtedness secured by any of the Mortgaged Property in priority to or pari passu with the lien securing the bonds. (See Section 4.03.) Other than as described above, the indenture does not limit the amount of indebtedness that we may incur. However, our issuance of long-term indebtedness is regulated by the California Public Utilities Commission.

Additional bonds which may be issued may vary from any existing bonds as to maturity, interest rate, redemption, sinking fund and in certain other respects as described above under the caption “General.”

Security for the Bonds

The bonds will be secured by the indenture which constitutes a first lien upon all of our real and personal property, other than Excepted Property, subject to Permissible Encumbrances, purchase money liens and liens on property at the time of acquisition. All of the bonds issued under the indenture will be equally and ratably secured by the indenture, subject to the provisions relating to any sinking or similar fund for the benefit of any bonds of a particular series.

Subject to such limitations and exceptions, all property acquired by us after the date of the indenture will be further security as described in the indenture. (See Section 5.09.) In addition, the indenture creates a prior lien on the Mortgaged Property to secure the trustees’ right to compensation, reimbursement and indemnity. (See Section 14.10.)

Ranking

The bonds of each series will be our secured and unsubordinated obligations and will rank equal in right of payment with all other bonds issued under the indenture. The bonds will rank first in right of payment with respect to proceeds from Mortgaged Property, and otherwise will rank equal in right of payment with all of our other unsubordinated and unsecured indebtedness. The bonds are our obligations exclusively, and are not the obligations of any of our subsidiaries or affiliates.

Payment of Bonds—Principal and Interest

We will pay principal of the bonds at stated maturity, upon redemption or otherwise, upon presentation of the bonds at the office of the trustee, as our paying agent. We will make payments on the bonds to the Depository Trust Company (“DTC”) or its nominee, as the registered owner of the bonds, by wire transfer of immediately available funds. If the securities are issued in definitive certificate form under the limited circumstances described below under the caption “Global Securities,” we will have the option of paying interest by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the trustee at least 15 days before the applicable payment date by the persons entitled to payment.

Form; Transfers; Exchanges

Bonds may be issued in denominations of $1,000, $5,000, $10,000, $25,000 or integral multiples of $25,000. The bonds will be issued in book-entry form represented by one or more global securities deposited with, or on behalf of, DTC, as depositary, and registered in the name of Cede & Co., its nominee. You will not be entitled to receive a certificate for the bonds that you purchase except under the limited circumstances described below under the caption “Global Securities.”

You will receive payments and may transfer bonds only through the facilities of DTC and its direct and indirect participants as described below under the caption Global Securities. We will maintain an office or agency where notices and demands in respect of the bonds and the indenture may be delivered to us and where certificated bonds may be surrendered for payment, registration of transfer or exchange, which will be at the principal office of the trustee, in San Francisco, California, and each other place specified by the trustee, including the Borough of Manhattan, City of New York, New York. (See Sections 2.01 and 2.03.)

Optional Redemption

Unless specified otherwise in an applicable prospectus supplement, we may redeem at our option at any time or from time to time all or any part of the bonds that we may offer and sell by this prospectus at the redemption price specified for the respective series of bonds. In the event that we elect to redeem only a portion of a series of bonds, the bonds to be redeemed shall be selected in accordance with DTC’s procedures, in the case of bonds represented by a global security, or by the trustee by a method the trustee deems to be fair and appropriate, in the case of bonds that are not represented by a global security. (See Section 7.01.)

We will mail notice of any redemption at least 30 days but not more than 60 days before the redemption date to each holder of the bonds to be redeemed. (See Section 7.02.) On or prior to the redemption date, we will deposit with the trustee a sum of money sufficient to redeem the bonds. (See Section 7.03.) Upon surrender of the bonds, we will pay the holders of the surrendered bonds the principal and accrued interest of the redeemed bonds

or, if only a portion of the principal of a particular bond is being redeemed, that portion of the principal and interest attributable to such redeemed portion. (See Sections 7.04 and 7.05.) All of the bonds redeemed and paid shall be cancelled. (See Section 7.06.)

Renewal Fund

We will pay to the trustee annually on April 1, as a renewal fund, an amount equal to (1) the amounts actually appropriated by us from earnings during the preceding calendar year as provisions for depreciation, depletion and retirements of Mortgaged Property and, if such appropriations are calculated on a sinking fund or similar compound interest method, including the portion thereof representing interest accrual as well as the portion thereof representing the annuity charge, minus (2) credits, taken at our option, for:

•

payments in cash or bonds made by us to a sinking fund or a similar fund under which cash paid to the trustee is to be used only to retire bonds;

•

the lesser of the cost or fair value of specified property additions purchased, constructed or otherwise acquired by us; and

•

the principal amount of bonds delivered to the trustee for such purpose, which will not be available for any other indenture purpose, including the issuance of additional bonds. (See Section 8.02.)

Renewal fund payments that we pay in cash may, at our option:

•

be withdrawn by us, subject to certain conditions, in an amount equal to the lesser of the cost or fair value of specified property additions purchased, constructed or otherwise acquired by us, or in an amount equal to the amount of Refundable Bonds made the basis for withdrawal; or

•

be applied to the purchase or redemption of any outstanding bonds.

At our election, the amount of any required renewal fund payment may be reduced by an amount equal to the amount of cash which, assuming that the renewal fund payments required to be made pursuant to the indenture had actually been made in cash, could at the time be withdrawn under the indenture. (See Section 8.06.) Any payments that we make to the renewal fund are in addition to the expenditures we are required to make for maintenance.

Consolidation, Merger and Transfer of Assets

Nothing in the indenture or in the bonds outstanding under the indenture prevents us from consolidating or merging with or into any corporation or selling all of our property as an entirety subject to the continuing lien of the indenture, provided that:

•

the terms of the consolidation, merger or sale preserve and do not impair the lien or the security under the indenture, and the rights and powers of the trustee and the holders of the bonds outstanding under the indenture;

•

in the case of a merger or consolidation, the successor corporation expressly assumes the payment of the principal and interest of all the bonds and the performance and observance of all of the covenants and conditions of the indenture; and

•

in the case of a sale of all of our property as an entirety, the corporation to which we sell all our property assumes the due and punctual payment of principal and interest of all the bonds outstanding under the indenture, assumes the performance of all covenants and conditions of the indenture and executes and delivers an indenture to the trustee whereby the purchasing corporation agrees to assume such payment and performance and charge therewith the property so taken over. (See Section 15.01.)

Certain Covenants

Subject to the terms of the indenture and in addition to the covenants otherwise specified above, we will:

•

keep, or cause to be kept, proper records and accounts of corporate dealings, including proper and complete records reflecting our capital and property accounts, and we will furnish statements upon demand as reasonably required by the trustee; (See Section 5.06.)

•

not voluntarily create any lien or charge that would be prior to the lien of the indenture upon the Mortgaged Property, other than purchase money liens and any other liens existing on property at the time such property was acquired by us; (See Section 5.09.)

•

pay or cause to be discharged all taxes, assessments, lawful claims and mechanics liens, which, if unpaid, might be given priority over the lien of the indenture; however, no such lien shall be a breach of the indenture if we are disputing it in good faith; (See Sections 5.09 and 5.10.)

•

file the indenture and any supplemental indenture as may be necessary to preserve and protect the security of the bondholders; (See Section 5.11.)

•

maintain, preserve and keep the mortgaged properties in good repair, working order and condition; (See Section 5.15.) and

•

maintain insurance on, or self-insure, the Mortgaged Property against losses or damages as are usually insured against by companies similarly situated and operating like properties. (See Section 5.16.)

Events of Default

The following events are defined for all purposes of the indenture (except where the term is otherwise defined for specific purposes) as “events of default”:

•

failure to pay the principal of any bond secured by the indenture when it becomes due and payable, whether at maturity, as therein expressed, or by declaration or otherwise;

•

failure to pay interest upon any bond secured by the indenture for a period of 30 days after it becomes due and payable;

•

failure to pay any installment of the sinking fund or renewal fund required by the indenture or of any sinking fund or analogous fund required by any supplemental indenture, for a period of 30 days after it becomes due and payable;

•

the adjudication of us as bankrupt by any court of competent jurisdiction;

•

the entry of an order approving a petition seeking the reorganization of us under the Federal Bankruptcy Laws or any other applicable law or statute of the United States of America, or any state thereof; or

•

the appointment of a trustee or a receiver of all or substantially all of our property;

unless during such period such adjudication, order or appointment of a receiver or trustee shall be vacated;

•

the filing by us of a voluntary petition in bankruptcy or the making of an assignment for the benefit of creditors; our consenting to the appointment of a receiver or trustee of all or any part of our property; the filing by us of a petition or answer seeking reorganization under the Federal Bankruptcy Laws, or any other applicable law or statute of the United States of America, or of any state thereof; or the filing by us of a petition to take advantage of any insolvency act; and

•

our failure to perform any other covenant or agreement contained in the indenture or any supplemental indenture or in any bond secured by the indenture for a period of 60 days following the mailing by the trustee to us of a written demand that such failure be cured, such failure not having been cured in the meantime. (See Section 9.02.)

Remedies

Acceleration

Upon the occurrence of an event of default, the trustee may, and upon the written request of the holders of a majority in principal amount of all bonds outstanding under the indenture shall, declare the principal amount of all of the bonds outstanding under the indenture, together with accrued and unpaid interest thereon, to be immediately due and payable. (See Section 9.05.)

Rescission of Acceleration

At any time after the principal of the bonds shall have been declared due and payable and before any sale of the Mortgaged Property shall have been made pursuant to the indenture,

•

all interest in arrears upon such bonds with interest on overdue installments of interest, to the extent that payment of such interest on interest shall be legally enforceable, at the same rate as was borne by the respective bonds on which installments of interest may be overdue,

•

together with reasonable charges and expenses of the trustee, its agents and attorneys, and

•

all other sums which may be due under the indenture, except the principal of such bonds as shall not have become due and payable by their terms,

shall either by paid by us to those entitled thereto (or to the trustee for their account) or be collected out of the Mortgaged Property, and all other defaults existing under the indenture known to the trustee shall have been cured or provision deemed by the trustee to be adequate therefor shall have been made, or shall have been waived as provided in the indenture, then and in every such case:

(a)

the holders of the majority in principal amount of the bonds then outstanding, by written notice to us and the trustee may waive such default and rescind and annul such declaration and its consequences, or

(b)

if in declaring the principal due, the trustee shall have acted without any request of the bondholders, or upon the request of the holders of less than 25% in principal amount of the bonds outstanding at the time of such request, and if there shall not have been delivered to the trustee and to us written directions to the contrary by the holders of not less than a majority in principal amount of the bonds then outstanding, then such default and its consequences ipso facto shall be deemed to be waived, or

(c)

if all such principal and interest which shall have matured otherwise than by such declarations shall have been made good and all other defaults cured or provided for or waived within 30 days after such declaration, then, without regard to any directions by the bondholders, all such defaults and their consequences ipso facto shall be deemed to be waived; and the parties shall be restored to their respective rights and obligations under the indenture as if no default had occurred; but no such waiver of any particular default shall extend to or affect or be deemed a waiver of any other default or impair any right consequent thereon. (See Section 9.05.)

Remedies with Respect to Mortgaged Property

To the extent permitted by law, upon the occurrence of an event of default the trustee may take actual possession of and enter, hold, use, operate and manage all of the Mortgaged Property and conduct the business, either personally or through the trustee’s agents. If the trustee takes such action, the trustee will receive the rents, income, issues and profits from the Mortgaged Property and, after deducting the costs and expenses of taking, holding, operating and managing the Mortgaged Property, including reasonable compensation to the trustee and its agents and counsel, taxes, assessments and expenses for any repairs, alterations and improvements, will apply such money first to interest owed and then to principal. (See Section 9.04.)

If one or more events of default occurs and continues without remedy for the designated period, the trustee may sell the Mortgaged Property or take appropriate judicial proceedings for the enforcement and protection of its rights and the rights of the bondholders. (See Section 9.06.)

Control by Holders; Limitations

The holders of a majority in principal amount of the bonds outstanding under the indenture will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power given to the trustee. The holders of a majority in principal amount of the bonds of any series will have the right, on behalf of all holders of the bonds of such series, to consent to the waiving of any past default and its consequences, other than a payment default. (See Sections 9.22 and 9.28.)

In addition, the indenture provides that no holder of bonds will have any right to institute any suit, action or proceeding, at law or in equity, for the foreclosure of the indenture, the execution of any trust with respect to the indenture, the appointment of a receiver, or for any other remedy under the indenture unless:

•

the holder has previously given the trustee written notice of a continuing event of default;

•

the holders of at least a majority in principal amount of the outstanding bonds have made written request upon the trustee and afforded the trustee a reasonable opportunity to exercise its powers under the indenture or institute the action, suit or proceeding in its own name;

•

the trustee has been offered reasonable security and indemnity against costs and liabilities incurred to comply with the request; and

•

the trustee has refused or failed to comply with the request within a reasonable time or to take other appropriate action for the enforcement of the indenture. (See Section 9.20.)

No holder will be entitled to institute any action to affect, disturb or prejudice the lien of the indenture, or to enforce any right under the indenture, except in the manner specified in the indenture, and actions must be instituted and maintained only according to the procedures established by the indenture and for the equal benefit of all bondholders. Each registered holder, however, has an unimpaired and unaffected right to receive payment when due and to bring a suit to enforce that right, unless this action would impair the lien of the indenture. (See Sections 9.20 and 9.21.)

Notice of Default

The trustee is required to give the bondholders notice of any default under the indenture known to the trustee, unless the default has been cured within 90 days after the occurrence of the default; provided, however, that except in the case of default in the payment of principal or interest of any bonds, or in the payment of any Maintenance and Sinking Fund installment, the trustee may withhold notice of default if and so long as our Board of Directors, the executive committee of our Board of Directors or a trust committee of directors and/or responsible officers of the trustee in good faith determine that the withholding of notice is in the interest of the bondholders. (See Section 9.03.)

Modification of the Indenture

The indenture may be modified by the consent of the holders of at least 66 ²/3% in principal amount of the bonds then outstanding, or in the event that less than all of the bonds of a particular series of bonds outstanding are affected by the modification, by the consent of the holders of 66 ²/3% in principal amount of the bonds of such series affected. The right of any holder to receive payment of principal and interest when due or the right of any holder to enforce such payment may not be changed without the consent of such holder. (See Section 16.05.)

Defeasance, Cancellation and Discharge

The lien on our property securing the bonds will be cancelled and discharged when the principal of and interest on the bonds has been paid or when we deposit with the trustee sufficient funds to repay the principal of and interest on all then outstanding bonds, and we request that the Mortgaged Property revert to us and that the lien be cancelled and discharged. Unless we request cancellation and discharge, the lien created by the indenture will not be cancelled and discharged, but shall remain in place for the issuance of future bonds pursuant to the terms of the indenture. (See Sections 11.01 and 11.02.)

Release Provisions

Unless an event of default has occurred and is continuing, we may, free from the lien of the indenture and at any time, without any release by the trustee, sell, exchange or dispose of obsolete machinery or equipment, provided we replace the machinery and equipment with other machinery and equipment of equivalent or greater value. (See Section 10.02.) In the absence of the occurrence and continuance of an event of default, we may also at any time and from time to time, without any release by the trustee:

•

cancel or modify our rights-of-way, leases or contracts, other than rights-of-way for transmission lines which require a release from the trustee;

•

surrender or modify any franchise or governmental consent or permit, so long as we may still conduct our business in the same territory for the same time;

•

abandon the operation of any of our properties if the operation of such property is not necessary or important for the operation of our other systems and plants or where such abandonment is deemed to be advisable;

•

produce, mine, sell or dispose of gas, oil, coal or other minerals, if any, lying or being within or under any real property which is part of the Mortgaged Property; and/or

•

dispose of, in the ordinary course of business, fuel, repair parts, repair material, operating supplies and commodities that comprise stock or merchandise kept for sale, manufactured commodities, gas and other personal property manufactured or acquired for sale in the ordinary course of business. (See Section 10.03.)

The indenture also contains provisions for the release of property by the trustee (i) upon a sale or exchange of such property provided that we receive compensation equal to the fair value of the property and that the release is advantageous to the conduct of the business and will not impair the Mortgaged Property, and (ii) for property taken by eminent domain, and in each case provided that the proceeds of any sale, exchange or taking by eminent domain are deposited with the trustee. (See Sections 10.04 and 10.05.)

Evidence of Compliance

The indenture provides that we will furnish to the trustee officers’ certificates, engineer’s certificates and, in certain cases, independent engineer’s certificates and independent accountant’s certificates in connection with the authentication of any bonds, the release or release and substitution of property and certain other matters, and opinions of counsel as to the lien of the indenture and certain other matters.

Preferred Stock

The preferred stock is issuable in series.

Additional Terms Applicable to Currently Authorized Preferred Stock and the Currently Authorized Preference Stock

Except as otherwise set forth below, the following provisions are applicable to all series of our currently authorized preferred stock and currently authorized preference stock, including currently outstanding shares and any additional shares that we may issue.

Ranking

All shares of currently authorized preferred stock rank senior to our currently authorized preference stock, and all shares of currently authorized preferred stock and currently authorized preference stock rank senior to our common stock, with respect to dividends and rights upon our liquidation, dissolution or winding up.

Dividend Rights

Registered holders of currently authorized preferred stock of each series are entitled to receive, when and as declared by our board of directors, out of any legally available funds, cumulative dividends at the rate established for the shares of the series, payable as may be authorized by the board of directors, before any dividends are paid on the preference stock or common stock.

Registered holders of currently authorized preference stock of each series are entitled to receive, when and as declared by our board of directors, out of any legally available funds, cumulative dividends at the rate established for the shares of the series, payable as may be authorized by the board of directors, before any dividends are paid on the common stock.

Liquidation Rights

In the event of our liquidation, dissolution or winding up, whether voluntary or involuntary, the registered holders of each series of the currently authorized preferred stock are entitled to receive out of our assets available for distribution to shareholders, the liquidation preference established for the shares of the series and accrued and unpaid dividends thereon before any distribution of assets is made to the registered holders of the currently authorized preference stock or common stock or any other security ranking junior to the currently authorized preferred stock. After payment in full to the registered holders of the currently authorized preferred stock, the registered holders of each series of the currently authorized preference stock are entitled to receive out of our assets available for distribution to shareholders, the liquidation preference established for the shares of the series and the accrued and unpaid dividends thereon before any distribution of assets is made to the registered holders of the common stock or any other security ranking junior to the currently authorized preference stock.

For all currently outstanding series of the preferred stock and series A preferred stock, the liquidation preference is $25 per share, and for all future series of the series preferred stock and the preference stock, the liquidation preference is the amount established therefor by the board of directors.

Redemption

The preferred stock and the preferred stock, series A are not redeemable. The series preferred stock and the preference stock may be redeemable, if at all, upon the terms established by the board of directors.

GLOBAL SECURITIES

The offered securities initially will be issued in book-entry form and represented by one or more global notes or global securities (collectively, “global securities”). The global securities will be deposited with, or on behalf of, The Depository Trust Company (“DTC”), New York, New York, as depositary, and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing offered securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

•

a limited-purpose trust company organized under the New York Banking Law;

•

a “banking organization” within the meaning of the New York Banking Law;

•

a member of the Federal Reserve System;

•

a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

•

a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934.

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, including transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, which eliminates the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is owned by a number of its direct participants and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others, which we sometimes refer to as “indirect participants,” that clear transactions through or maintain a custodial relationship with a direct participant either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of offered securities within the DTC system must be made by or through direct participants, which will receive a credit for those offered securities on DTC’s records. The ownership interest of the actual purchaser of an offered security, which we sometimes refer to as a “beneficial owner,” is in turn recorded on the direct and indirect participants’ records. Beneficial owners of offered securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased offered securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities except in the event that use of the book-entry system for the securities is discontinued.

To facilitate subsequent transfers, all global securities deposited with DTC will be registered in the name of DTC’s nominee, Cede & Co. The deposit of offered securities with DTC and their registration in the name of Cede & Co. will not change the beneficial ownership of the offered securities. DTC has no knowledge of the actual beneficial owners of the offered securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

So long as the securities are in book-entry form, you will receive payments and may transfer offered securities only through the facilities of the Depositary and its direct and indirect participants. We will maintain an

office or agency in the Borough of Manhattan, the City of New York, New York where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange. That office or agency will initially be the office of the trustee, which is currently located at 100 Wall Street, Suite 1600, New York, New York 10005.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the offered securities of a particular series are being redeemed, DTC will determine the amount of the interest of each direct participant in the offered securities of such series to be redeemed in accordance with DTC’s procedures.

In any case where a vote may be required with respect to offered securities of a particular series, neither DTC nor Cede & Co. will give consents for or vote the global securities unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the offered securities of such series are credited on the record date identified in a listing attached to the omnibus proxy.

So long as offered securities are in book-entry form, we will make payments on those offered securities to the depositary or its nominee, as the registered owner of such offered securities, by wire transfer of immediately available funds. If offered securities are issued in definitive certificated form under the limited circumstances described below we will have the option of paying interest by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the trustee at least 15 days before the payment date by the persons entitled to payment.

Principal and interest payments on the offered securities will be made to Cede & Co., as nominee of DTC. DTC’s practice is to credit direct participants’ accounts on the relevant payment date. Payments by direct and indirect participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with offered securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any legal requirements in effect from time to time. Payment of principal and interest to Cede & Co. is our responsibility, disbursement of payments to direct participants is the responsibility of DTC and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of offered securities will not be entitled to have offered securities registered in their names and will not receive physical delivery of offered securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the offered securities and the indenture.

The laws of some jurisdictions may require that some purchasers of offered securities take physical delivery of offered securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in offered securities.

DTC is under no obligation to provide its services as depositary for the offered securities and may discontinue providing its services at any time. Neither we nor the trustee will have any responsibility for the performance by DTC or its direct participants or indirect participants under the rules and procedures governing DTC.

As noted above, beneficial owners of a particular series of offered securities generally will not receive certificates representing their ownership interests in those offered securities. However, if:

•

DTC notifies us that it is unwilling or unable to continue as a depositary for the global security or securities representing such series of offered securities or if DTC ceases to be a clearing agency registered under the Securities Exchange Act at a time when it is required to be registered and a successor depositary is not appointed within 90 days of the notification to us or of our becoming aware of DTC’s ceasing to be so registered, as the case may be;

•

we determine, in our sole discretion, not to have the offered securities of such series represented by one or more global securities of such series; or

•

an event of default under the indenture has occurred and is continuing with respect to the offered securities,

we will prepare and deliver certificates for the offered securities of such series in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

We have obtained the information in this section and elsewhere in this prospectus concerning DTC and DTC’s book-entry system from sources that are believed to be reliable, but we do not take responsibility for the accuracy of this information.
