using a shelf registration statement, we may sell up to $350,000,000 aggregate
principal amount of bonds, determined based upon the issue price at stated
principal or at a discount from stated principal, from time to time and in one
or more offerings. This prospectus only provides you with a general description
of the bonds that we may offer. Each time we sell bonds, we will provide a
supplement to this prospectus that contains specific information about the
terms of the bonds. The supplement may also add, update or change information
contained in this prospectus. Before purchasing bonds, you should carefully
read both this prospectus and the accompanying prospectus supplement, together
with the additional information described under the heading "Where You Can Find
More Information."

   You should rely only on the information contained or incorporated by
reference in this prospectus and in any prospectus supplement. We have not
authorized any other person to provide you with different information. If
anyone provides you with different or inconsistent information, you should not
rely on it. We will not make an offer to sell the bonds in any jurisdiction
where the offer or sale is not permitted. You should assume that the
information appearing in this prospectus and the accompanying prospectus
supplement is accurate as of the date on their respective covers. Our business,
financial condition, results of operations and prospects may have changed since
that date.


                           FORWARD-LOOKING STATEMENTS

   This prospectus, any accompanying prospectus supplement and the documents
they incorporate by reference may contain statements that are not historical
fact and constitute forward-looking statements. When we use words like
"believes," "expects," "anticipates," "intends," "plans," "estimates," "may,"
"should" or similar expressions, or when we discuss our strategy or plans, we
are making forward-looking statements. Forward-looking statements are not
guarantees of performance. They involve risks, uncertainties and assumptions.
Our future results may differ materially from those expressed in these forward-
looking statements. These statements are necessarily based upon various
assumptions involving judgments with respect to the future and other risks,
including, among others:

  . national, international, regional and local economic, competitive,
    technological, political, legislative and regulatory conditions and
    developments;

  . actions by the California Public Utilities Commission, the California
    State Legislature and the Federal Energy Regulatory Commission;

  . the financial condition of other natural gas distribution companies and
    investor-owned utilities;

  . capital market conditions, inflation rates, exchange rates and interest
    rates;

  . decisions by rating agencies regarding our debt ratings;

  . energy markets, including the timing and extent of changes in commodity
    prices;

  . weather conditions;

  . business, regulatory and legal decisions;

  . the actions by federal, state and regulatory officials affecting
    deregulation of retail natural gas delivery both in California and in
    other energy markets;

  . the timing and success of business development efforts; and

  . other uncertainties, all of which are difficult to predict and many of
    which are beyond our control.

   You are cautioned not to rely unduly on any forward-looking statements.
These risks and uncertainties are discussed in more detail under "Business" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in our Annual Report on Form 10-K for the year ended December 31,
2000, our Quarterly Reports on Form 10-Q for the three-month periods ended
March 31, 2001 and June 30, 2001, and other documents on file with the SEC. You

                      DESCRIPTION OF FIRST MORTGAGE BONDS

   The following is a general description of the terms and provisions of the
bonds we may offer and sell by 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 as described in this
prospectus.

   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 Trust National Association, as trustee, together with
the applicable supplemental indentures, relating to the issuance of each series
of bonds by us (as 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 following its
execution. 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. 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, 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
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 of the particular
series of bonds will be determined by the 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;

                                       5


  . 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 of the bonds that may supplement those described below.
    (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:

  . 66 2/3% of the Net Bondable Value of Property Additions that have not
    been applied to other indenture purposes; (Section 4.04)

  . 100% of the amount of cash deposited with the trustee for the purpose of
    issuing additional bonds; (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. (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. (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 twelve consecutive months in the past fifteen 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. (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. (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. (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

                                       6


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.

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
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. (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 in the respective series of bonds. In the event that we elect to
redeem only a portion of a series of bonds, the particular bonds of such series
to be redeemed will be selected by the trustee by lot in such manner as the
trustee deems fair. (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.
(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. (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. (Sections 7.04
and 7.05) All of the bonds redeemed and paid shall be cancelled. (Section 7.06)

Renewal Fund

   We will pay to the trustee annually on April 1, as a renewal fund, an amount
equal to our Appropriations of Earnings for Depreciation of Mortgaged Property
during the preceding calendar year, minus 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


                                       7


  . 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.

(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. (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 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. (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; (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; (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; (Section 5.09, 5.10)

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

                                       8



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


  . maintain insurance, which may be self-insured, on the Mortgaged Property
    against losses or damages as are usually insured against by companies
    similarly situated and operating like properties. (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
    the same shall become 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 such interest shall have become 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 the
    same shall have become due and payable;

  . the expiration of a period of 60 days following:

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

    . the entry of an order approving a petition seeking the reorganization

      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; the consenting by us to the
    appointment of a receiver or trustee of all or any part of its 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;


  . 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.

   The trustee may, and, if required in writing to do so by the holders of a
majority in principal amount of the bonds then outstanding, shall make such
demand. (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. (Section 9.05)

                                       9


 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 trust estate 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. (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 net of 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. (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 in the
alternative, take appropriate judicial proceedings for the enforcement and
protection of its rights and the rights of the bondholders. (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


                                       10



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. (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; and


  . 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. (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. (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 the board of directors, the
executive committee of the 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. (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. (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. (Sections 11.01 and 11.02)

                                       11


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. (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. (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. (Sections 10.04, 10.05)


Evidence of Compliance

   The indenture provides that we will furnish to the trustee officer's
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.


Concerning the Trustee

   U.S. Bank Trust National Association, a national banking association, duly
organized and existing under the laws of the United States of America, has been
appointed as the trustee. The principal office of the trustee is located at 500
South Hope Street, Suite 500, Los Angeles, California, 90071.

   The trustee may resign at any time by giving us written notice and by
publishing notice in a required newspaper. The resignation will be effective
either on the date specified in the notice or on the date of appointment of a
successor trustee. The holders of a majority in principal amount of the
outstanding bonds may remove the trustee by signing, acknowledging, and filing
with the trustee a written instrument or concurrent written instruments. Under
certain circumstances, we may appoint a successor trustee. (Sections 14.16
and 14.17)


No Liability for Stockholders, Directors and Officers

   None of our present, past or future stockholders, directors or officers will
be liable for any payments of principal or interest on the bonds, or for any
claim based on any payment of principal or interest, or on the indenture or any
supplemental indenture. (Article XII)

  otherwise included, the net earnings or net losses of such property
  additions or of such other corporation, as the case may be, for the whole
  of such period. The net earnings of such property additions, or of such
  other corporation, for the period preceding such acquisition or such
  consolidation or merger, shall be ascertained and computed as provided in
  the foregoing subdivisions of this definition as if such property additions
  or the assets of such other corporation, as the case may be, had been owned
  by the Company during the whole of such period, or as if such other
  corporation had been consolidated or merged with the Company prior to the
  first day of such period.


     (g) In case the Company shall have obtained the release of property of
  an aggregate fair value in excess of One Million Dollars ($1,000,000), as
  shown by the engineer's certificate, or shall have obtained the release of
  property of which the aggregate proceeds of which shall have exceeded One
  Million Dollars ($1,000,000), within or after the particular period for
  which the calculation of net earnings of the Corporation available for
  interest is made, then, in computing the Net Earnings of the Corporation
  Available for Interest, the net earnings or net losses of such property for
  the whole of such period shall be excluded to the extent possible on the
  basis of actual earnings and expenses of such property or on the basis of
  such estimates of the earnings and expenses of such property as the signers
  of an officers' certificate filed with the trustee shall deem proper.


     (h) The Net Earnings of the Corporation Available for Interest, whether
  of the Company or of some other corporation or of property, shall be
  determined in accordance with principles of sound accounting practice.

   "Net Investment in Mortgaged Property" means as of any particular time the
total cost of the Mortgaged Property less the then related reserves for
depreciation, depletion and amortization or other reserves for retirement of
such property; all determined in compliance with the Uniform System of Accounts
for Gas Corporations prescribed by the Public Utilities Commission of the State
of California, effective January 1, 1949, or in compliance with such system of
accounts as said Commission or other similar regulatory body may from time to
time prescribe, or to the extent that any such system is not so prescribed or
is not applicable, then in accordance with sound accounting practice.

   "Permissible Encumbrances" means:

     (a) the lien of taxes and assessments not at the time due;

     (b) the lien of taxes for the then current year;

     (c) the lien of specified taxes and assessments already due but the
  validity of which is being contested at the time by the Company in good
  faith, unless thereby in the opinion of counsel any of the Mortgaged
  Property may be lost or forfeited;


     (d) undetermined liens and charges incidental to construction;

     (e) the right reserved to, or vested in, any municipality or public
  authority by the terms of any right, power, franchise, grant, license,
  permit or by any provision of law, to purchase or recapture or to designate
  a purchaser of, any of the Mortgaged Property;

     (f) liens upon rights-of-way for transmission or distribution line
  purposes, provided that the Company has, in the opinion of counsel, power
  under eminent domain or similar statutes to condemn or acquire

                                       15



  easements or rights-of-way sufficient for its purposes over the land
  covered by the easements or rights-of-way in question or other lands
  adjacent thereto;


     (g) easements or similar encumbrances the existence of which in the
  opinion of the signers of an engineer's certificate filed at the particular
  time, does not impair the use of the property described in such certificate
  for the purposes for which it was acquired or is then used; and


     (h) possible adverse rights or interests which, in the opinion of
  counsel, are unimportant and may properly be disregarded.

   "Refundable Bonds" means, at any particular time, all bonds which shall
theretofore have been authenticated and delivered under the provisions of the
indenture and issued by the Company and bonds, not issued by the Company, which
have been established as refundable pursuant to the indenture; provided that
such bonds, whether authenticated under the indenture or established as
refundable, shall have been theretofore paid at maturity or redeemed or
purchased (otherwise than out of funds included in the Trust Estate) and
surrendered to the trustee, either canceled or uncanceled, or surrendered to
the trustee for conversion (if convertible), or otherwise surrendered to the
trustee, subject to certain exceptions provided in the indenture, and which
shall not theretofore have been made the basis for the authentication and
delivery of additional bonds or the withdrawal of cash under the provisions of
the indenture or the reduction of the amount of cash to be deposited under the
provisions of the indenture or paid or redeemed or purchased pursuant to, or
used to reduce the amount of cash to be deposited pursuant to, or otherwise
retired through the operation of, or used in compliance with the requirements
of, the provisions of the maintenance and sinking fund established by the
indenture or of any sinking fund, amortization fund, or analogous fund
established by any indenture supplemental to the indenture, which does not
permit the authentication of additional bonds upon the basis of bonds so paid,
redeemed, purchased, retired, or used.


   Bonds and coupons for the payment or redemption of which moneys shall have
been deposited (whether at or prior to maturity or the redemption date of such
bonds) with the trustee if such bonds were issued under the indenture, or with
the trustee of the other indenture under which such bonds were issued, shall be
deemed to have been paid within the meaning of this definition; provided,
however, that if such bonds are to be redeemed prior to the maturity thereof,
notice of such redemption shall be given as described above under the caption
"Optional Redemption" or as provided pursuant to the redemption provisions of
such other indenture, as the case may be, or provisions satisfactory to the
trustee shall have been made for such publication.

                                       16


                               GLOBAL SECURITIES

   Unless indicated otherwise in any prospectus supplement, the bonds initially
will be issued in book-entry form and represented by one or more global notes
or global securities (collectively, "global securities"). If issued in book-
entry form, the global securities will be deposited with, or on behalf of, The
Depository Trust Company, New York, New York, as depositary ("DTC"), and
registered in the name of Cede & Co., its nominee. Unless and until it is
exchanged for individual certificates evidencing bonds 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 LLC 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 bonds within the DTC system must be made by or through direct
participants, which will receive a credit for those bonds on DTC's records. The
ownership interest of the actual purchaser of a debt security, which we
sometimes refer to as a "beneficial owner," is in turn recorded on the direct
and indirect participants' records. Beneficial owners of bonds 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 whom they purchased bonds. 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 under the limited circumstances described below.

   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
bonds with DTC and their registration in the name of Cede & Co. will not change
the beneficial ownership of the bonds. DTC has no knowledge of the actual
beneficial owners of the bonds. 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.

   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.

                                       17


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

   In any case where a vote may be required with respect to bonds of a
particular series, neither DTC nor Cede & Co. will give consents for or vote
the global securities. 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 bonds of such series are credited on the
record date identified in a listing attached to the omnibus proxy.

   We will make payments on global securities to the depositary or its nominee,
as the registered owner of such bonds, by wire transfer of immediately
available funds. If bonds 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 global 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 unless DTC has reason to believe that it
will not receive payment on the 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 bonds 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 bonds
will not be entitled to have bonds registered in their names and will not
receive physical delivery of bonds. Accordingly, each beneficial owner must
rely on the procedures of DTC and its participants to exercise any rights under
the bonds and the indenture.

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

   DTC is under no obligation to provide its services as depositary for the
bonds 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 bonds generally
will not receive certificates representing their ownership interests in those
bonds. 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 bonds 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 bonds 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 bonds of such series,

we will prepare and deliver certificates for the bonds 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

                                       18


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.

                                       19


                              PLAN OF DISTRIBUTION

   We may sell the bonds described in this prospectus from time to time in one
or more transactions:

  . to purchasers directly;

  . to underwriters for public offering and sale by them;

  . through agents;

  . through dealers; or

  . through a combination of any of the foregoing methods of sale.

   We may distribute the bonds from time to time in one or more transactions
at:

  . a fixed price or prices, which may be changed;

  . market prices prevailing at the time of sale;

  . prices related to such prevailing market prices; or

   .negotiated prices.

 Direct Sales

   We may sell the bonds directly to institutional investors or others. A
prospectus supplement will describe the terms of any sale of bonds we are
offering hereunder.

 To Underwriters

   The prospectus supplement will name any underwriter involved in a sale of
bonds. Underwriters may offer and sell securities at a fixed price or prices,
which may be changed, or from time to time at market prices or at negotiated
prices. Underwriters may be deemed to have received compensation from us from
sales of bonds in the form of underwriting discounts or commissions and may
also receive commissions from purchasers of bonds for whom they may act as
agent.

   Underwriters may sell the bonds to or through dealers, and such dealers may
receive compensation in the form of discounts, concessions or commissions from
the underwriters and/or commissions, which may be changed from time to time,
from the purchasers for whom they may act as agent.

   Unless otherwise provided in a prospectus supplement, the obligations of any
underwriters to purchase bonds will be subject to certain conditions precedent,
and the underwriters will be obligated to purchase all the bonds of such series
if they purchase any.

 Through Agents and Dealers

   We will name any agent involved in a sale of the bonds, as well as any
commissions payable by us to such agent, in a prospectus supplement. Unless we
indicate differently in the prospectus supplement, any such agent will be
acting on a reasonable efforts basis for the period of its appointment.

   If we utilize a dealer in the sale of the bonds being offered pursuant to
this prospectus, we will sell the bonds to the dealer, as principal. The dealer
may then resell the bonds to the public at varying prices to be determined by
the dealer at the time of resale.

                                       20


 Delayed Delivery Contracts

   If we so specify in the applicable prospectus supplement, we will authorize
underwriters, dealers and agents to solicit offers by certain institutions to
purchase bonds pursuant to contracts providing for payment and delivery on
future dates. Such contracts will be subject to only those conditions set forth
in the applicable prospectus supplement.

   The underwriters, dealers and agents will not be responsible for the
validity or performance of the contracts. We will set forth in the prospectus
supplement relating to the contracts the price to be paid for the bonds, the
commissions payable for solicitation of the contracts and the date in the
future for delivery of the securities.

 General Information

   Underwriters, dealers and agents participating in a sale of the bonds may be
deemed to be underwriters as defined in the Securities Act of 1933 (the
"Securities Act"), and any discounts and commissions received by them and any
profit realized by them on resale of the securities may be deemed to be
underwriting discounts and commissions, under the Securities Act. We may have
agreements with underwriters, dealers and agents to indemnify them against
certain civil liabilities, including liabilities under the Securities Act, and
to reimburse them for certain expenses.

   Underwriters or agents and their associates may be customers of, engage in
transactions with or perform services for us or our affiliates in the ordinary
course of business.

   Unless we indicate differently in a prospectus supplement, we will not list
the bonds on any securities exchange. The bonds will be a new issue of
securities with no established trading market. Any underwriters that purchase
bonds for public offering and sale may make a market in such bonds, but such
underwriters will not be obligated to do so and may discontinue any market
making at any time without notice. We make no assurance as to the liquidity of
or the trading markets for any bonds.

   are estimated.

Item 15. Indemnification of Officers and Directors.

   Section 317 of the Corporations Code of the State of California permits a
corporation to provide indemnification to its directors and officers under
certain circumstances. The Southern California Gas Company Restated Articles of
Incorporation and Bylaws eliminate the liability of directors for monetary
damages to the fullest extent permissible under California law and provide that
indemnification for liability for monetary damages incurred by directors,
officers and other agents of Southern California Gas Company shall be allowed,
subject to certain limitations, in excess of the indemnification otherwise
permissible under California law. In addition, Southern California Gas Company
has indemnification agreements with each of its officers and directors that
provide for indemnification for monetary damages to the fullest extent
permissible under California law. Southern California Gas Company maintains
liability insurance and is also insured against loss for which it may be
required or permitted by law to indemnify its directors and officers for their
related acts.

   The directors and officers of Southern California Gas Company are covered by
insurance policies indemnifying them against certain liabilities, including
certain liabilities arising under the Securities Act, which might be incurred
by them in such capacities and against which they cannot be indemnified by
Southern California Gas Company.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the registrant
pursuant to the foregoing provisions, the registrant has been informed that in
the opinion of the SEC such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

Item 17. Undertakings.

   The undersigned registrant hereby undertakes:

   (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

     (i) to include any prospectus required by Section 10(a)(3) of the
  Securities Act;

     (ii) to reflect in the prospectus any facts or events arising after the
  effective date of the Registration Statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Securities and
  Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the
  changes in volume and price represent no more than a 20% change in the
  maximum aggregate offering price set forth in the Calculation of
  Registration Fee table in the effective Registration Statement; and

     (iii) to include any material information with respect to the plan of
  distribution not previously disclosed in the Registration Statement or any
  material change to such information in the Registration Statement;

provided, however, that (i) and (ii) do not apply if the information required
to be included in a post-effective amendment by those paragraphs is contained
in periodic reports filed with or furnished to the Securities and Exchange
Commission by the registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the Registration Statement.

   (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

   (3) To remove from registration by means of post-effective amendment any of
the securities being registered that remain unsold at the termination of the
offering.

   (4) That, for purposes of determining any liability under the Securities
Act, each filing of Southern California Gas Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by
reference in this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

   (5) To file an application for the purpose of determining the eligibility of
the trustee to act under subsection (a) of Section 310 of the Trust Indenture
Act in accordance with the rules and regulations prescribed by the Securities
and Exchange Commission under Section 305(b)(2) of the Securities Act.

                                      II-5


   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under item 15 above, or
otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                      II-6
