(1)  An indeterminate principal amount or number of debt securities, common
     stock and/or preferred stock and guarantees of Sempra Energy, an
     indeterminate principal amount of debt securities of Sempra Energy
     Holdings and an indeterminate number of preferred securities of the Trusts
     as may from time to time be issued at indeterminate prices, with an
     aggregate offering price not to exceed $1,000,000,000. Debt securities may
     be issued and sold to the Trusts, in which event the debt securities may
     later be distributed to the holders of preferred securities.
 
(2)  In United States dollars or the equivalent thereof in any other currency,
     composite currency or currency unit as shall result in an aggregate
     initial offering price for all securities of $1,000,000,000.
 
(3)  This amount represents the principal amount of any debt securities issued
     at their principal amount, the issue price of any debt securities issued
     at an original issue discount, the issue price of any preferred stock and
     preferred securities and the amount computed pursuant to Rule 457(c) for
     any common stock.
 
(4)  Estimated solely for the purpose of calculating the registration fee,
     which is calculated in accordance with Rule 457(o) of the rules and
     regulations under the Securities Act of 1933. Rule 457(o) permits the
     registration fee to be calculated on the basis of the maximum offering
     price of all of the securities listed and, therefore, the table does not
     specify by each class information as to the amount to be registered, the
     proposed maximum offering price per unit or the proposed maximum aggregate
     offering price.
 
(5)  The Rights are initially carried and traded with the common stock. The
     value attributable to the Rights, if any, is reflected in the value of the
     common stock.
 
(6)  Also includes an indeterminate number of securities that may be issued
     upon conversion or exchange of any securities registered hereunder that
     provide for conversion or exchange.
 
(7)  Includes the rights of holders of the preferred securities under the
     guarantees of preferred securities and back-up undertakings, consisting of
     obligations by Sempra Energy, as set forth in the declaration of trust,
     the applicable indenture and any supplemental indenture thereto, in each
     case as further described in the Registration Statement. No separate
     consideration will be received for any guarantees or any back-up
     undertakings.

  The Registrants hereby amend this Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrants
shall file a further amendment which specifically states that this Registration
Statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933 or until this Registration Statement shall become
effective on such date as the Securities and Exchange Commission, acting
pursuant to said Section 8(a), may determine.

 
The information in this prospectus is not complete and may be changed. We may
not sell these securities until the registration statement filed with the
Securities and Exchange Commission is effective. This prospectus is not an
offer to sell these securities and it is not soliciting an offer to buy these
securities in any state where the offer or sale is not permitted.

                             ABOUT THIS PROSPECTUS
 
  This prospectus is part of a "shelf" registration statement that we filed
with the United States Securities and Exchange Commission, or the "SEC." By
using a shelf registration statement, we may sell up to $1,000,000,000 offering
price of any combination of the securities described in this prospectus from
time to time and in one or more offerings. This prospectus only provides you
with a general description of the securities that we may offer. Each time we
sell securities, we will provide a supplement to this prospectus that contains
specific information about the terms of the securities. The supplement may also
add, update or change information contained in this prospectus. Before
purchasing any securities, you should carefully read both this prospectus and
any supplement, together with the additional information described under the
heading "Where You Can Find More Information."
 
  This prospectus does not contain separate financial statements for Sempra
Energy Holdings or the trusts. Sempra Energy files consolidated financial
information with the SEC that includes Sempra Energy Holdings and each of the
trusts. The trusts do not have any independent function other than to issue
securities and to purchase subordinated notes from Sempra Energy. We do not
believe that additional financial information regarding Sempra Energy Holdings
or the Trusts would be useful to you.
 
  You should rely only on the information contained or incorporated by
reference in this prospectus and in any 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 these securities in any jurisdiction where the offer
or sale is not permitted. You should assume that the information appearing in
this prospectus and the supplement to this prospectus is accurate as of the
dates on their 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 additional
information described under the heading "Where You Can Find More Information"
may contain forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995. These statements are subject to risks
and uncertainties and are based on the beliefs and assumptions of our
management, based on information currently available to our management. When we
use words such as "believes," "expects," "anticipates," "intends," "plans,"
"estimates," "should" or similar expressions, we are making forward-looking
statements. Forward-looking statements include the information concerning
possible or assumed future results of operations set forth under "Business" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in our Annual Report on Form 10-K incorporated by reference into
this prospectus.
 
  Forward-looking statements are not guarantees of performance. They involve
risks, uncertainties and assumptions. Our future results and shareholder value
may differ materially from those expressed in these forward-looking statements.
Many of the factors that will determine these results and value are beyond our
ability to control or predict. These statements are necessarily based upon
various assumptions involving judgments with respect to the future including,
among others, our ability to achieve synergies and revenue growth, national,
international, regional and local economic, competitive and regulatory
conditions and developments, technological developments, capital market
conditions, inflation rates, interest rates, energy markets, weather
conditions, business and regulatory or legal decisions, the pace of
deregulation of retail natural gas and electricity, the timing and extent of
changes in commodity prices for oil, natural gas and electricity, and some
agricultural products, 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 put undue reliance on
any forward-looking statements. For those statements, we claim the protection
of the safe harbor for forward-looking statements contained in the Private
Securities Litigation Reform Act of 1995.
 
  You should also consider any other factors contained in this prospectus or in
any accompanying supplement, including the information incorporated by
reference into this prospectus or into any accompanying supplement.

                                   THE TRUSTS
 
  Sempra Energy created three Delaware business trusts pursuant to three
Declarations of Trust. The trusts are named Sempra Energy Capital Trust I,
Sempra Energy Capital Trust II and Sempra Energy Capital Trust III. Sempra
Energy will file an Amended and Restated Declaration of Trust (a "Declaration")
for each trust, which will state the terms and conditions for each trust to
issue and sell its preferred securities and common securities. A form of
Declaration is filed as an exhibit to the registration statement of which this
prospectus forms a part.
 
  Each trust will exist solely to:
 
  . issue and sell its preferred securities (representing undivided
    beneficial interests in the trust) to the public;
 
  . issue and sell its common securities (representing undivided beneficial
    interests in the trust) to Sempra Energy;
 
  . use the proceeds from the sale of its preferred and common securities to
    purchase a series of Sempra Energy's subordinated debt securities;
 
  . distribute the cash payments it receives on the subordinated debt
    securities it owns to the holders of the preferred and common securities;
 
  . maintain its status as a grantor trust for federal income tax purposes;
    and
 
  . engage in other activities that are necessary or incidental to these
    purposes.
 
  Sempra Energy will purchase all of the common securities of each trust. The
common securities will represent an aggregate liquidation amount equal to at
least 3% of each trust's total capitalization. The preferred securities will
represent the remaining 97% of the trust's total capitalization. The common
securities will have terms substantially identical to, and will rank equal in
priority of payment with, the preferred securities. However, if Sempra Energy
defaults on the related subordinated debt securities, then cash distributions
and liquidation, redemption and other amounts payable on the common securities
will be subordinate to the preferred securities in priority of payment.
 
  The preferred securities will be guaranteed by Sempra Energy as described
later in this prospectus.
 
  Sempra Energy has appointed five trustees to conduct each trust's business
and affairs:
 
  . The Bank of New York ("property trustee");
 
  . The Bank of New York ("Delaware trustee"); and
 
  . Three Sempra Energy officers ("regular trustees").
 
  Only Sempra Energy, as owner of the common securities, can remove or replace
the trustees. In addition, Sempra Energy can increase or decrease the number of
trustees. However, the majority of trustees will always be regular trustees.
 
  Sempra Energy will pay all fees and expenses related to each trust and each
offering of the related preferred securities and will pay all ongoing costs and
expenses of each trust, except the respective trust's obligations under the
related preferred and common securities.
 
                                       5

 
  The trusts will not have separate financial statements. The statements would
not be material to holders of the preferred securities because no trust will
have any independent operations. Each trust exists solely for the reasons
summarized above.
 
                                USE OF PROCEEDS
 
  Unless stated otherwise in the applicable prospectus supplement, the net
proceeds from the sale of the offered securities will be:
 
  . used by Sempra Energy and/or its subsidiaries for general corporate
    purposes, including investing in unregulated business activities and
    reducing short-term debt incurred to provide interim financing for such
    purposes; and
 
  . used by the respective trusts to purchase subordinated debt securities of
    Sempra Energy.

                           DESCRIPTION OF SECURITIES
 
  The following is a general description of the terms and provisions of the
securities we may offer and sell by this prospectus. These summaries are not
meant to be a complete description of each security. This prospectus and any
accompanying prospectus supplement will contain the material terms and
conditions for each security. The prospectus supplement may add, update or
change the terms and conditions of the securities as described in this
prospectus. For more information about the securities offered by us, please
refer to:
 
  . the indenture between Sempra Energy and Citibank, N.A., as trustee
    relating to the issuance of each series of senior debt securities by
    Sempra Energy;
 
  . the indenture ("subordinated indenture") between Sempra Energy and The
    Bank of New York, as trustee relating to the issuance of each series of
    subordinated debt securities by Sempra Energy;
 
  . the indenture among Sempra Energy Holdings, Sempra Energy, as Guarantor
    and U.S. Bank Trust Company, as trustee relating to the issuance of each
    series of senior debt securities by Sempra Energy Holdings;
 
  . the Declaration of each trust; and
 
  . Sempra Energy's guarantee of the preferred securities issued by each
    trust.
 
  Forms of these documents are filed as exhibits to the registration statement.
The indentures listed above are sometimes collectively referred to as the
"indentures" and individually referred to as an "indenture." The indentures are
subject to and governed by the Trust Indenture Act of 1939, as amended, and may
be supplemented or amended from time to time following their execution.
 
                         DESCRIPTION OF DEBT SECURITIES
 
  The following description sets forth the general terms and provisions of the
debt securities that Sempra Energy and Sempra Energy Holdings may offer by this
prospectus. The debt securities may be issued as senior debt securities or
subordinated debt securities in the case of Sempra Energy and as senior debt
securities in the case of Sempra Energy Holdings. The indebtedness represented
by the senior debt securities will rank equally with all other unsecured and
unsubordinated debt of the company issuing the senior debt security (either
Sempra Energy or Sempra Energy Holdings). The indebtedness represented by the
subordinated debt securities will rank junior and subordinate in right of
payment to the prior payment in full of the senior debt of Sempra Energy, to
the extent and in the manner set forth in the prospectus supplement for the
securities. See "--Subordination" below. Throughout this description,
references to "we," "us" and "our" should be read to refer to the company
issuing the particular securities, unless the context indicates that "we," "us"
or "our" refers to both Sempra Energy and Sempra Energy Holdings.
 
  Each indenture gives us broad authority to set the particular terms of each
series of debt securities, including the right to modify certain of the terms
contained in the indenture. The particular terms of a series of 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 the debt securities.
 
  Each 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 debt securities or the applicable
 
                                       7

 
indentures. This summary is subject to and qualified in its entirety by
reference to all the provisions of the applicable indenture, including
definitions of terms used in the indenture. We also include references in
parentheses to certain sections of the indentures. Whenever we refer to
particular sections or defined terms of the indentures in this prospectus or in
a prospectus supplement, these sections or defined terms are incorporated by
reference herein or in the prospectus supplement. This summary also is subject
to and qualified by reference to the description of the particular terms of the
debt securities described in the applicable prospectus supplement or
supplements.
 
General
 
  We may issue an unlimited amount of debt securities under the indentures in
one or more series. We need not issue all debt securities of one series at the
same time and, unless otherwise provided, we may reopen a series, without the
consent of the holders of the debt securities of that series, for issuances of
additional debt securities of that series.
 
  The debt securities of Sempra Energy and Sempra Energy Holdings will be
unsecured obligations of the company issuing the security, and the debt
securities of Sempra Energy Holdings will be unconditionally guaranteed by
Sempra Energy as to payment of principal, premium, if any, and interest. See
"Guarantee of Sempra Energy; Holding Company Structure."
 
  Prior to the issuance of each series of debt securities, the terms of the
particular securities will be specified in a supplemental indenture (including
any pricing supplement) and a board resolution of the issuing company or in one
or more officer's certificates of the issuing company pursuant to a
supplemental indenture or a board resolution. We refer you to the applicable
prospectus supplement for a description of the following terms of the series of
debt securities:
 
  (a) the title of the debt securities;
 
  (b) any limit upon the principal amount of the debt securities;
 
  (c) the date or dates on which principal will be payable or how to
      determine the dates;
 
  (d) the rate or rates or method of determination of 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;
 
  (e) any obligation or option of the issuing company to redeem, purchase or
      repay debt securities, or any option of the registered holder to
      require the issuing company to redeem or repurchase debt securities,
      and the terms and conditions upon which the debt securities will be
      redeemed, purchased or repaid;
 
  (f) the denominations in which the debt securities will be issuable (if
      other than denominations of $1,000 and any integral multiple thereof);
 
  (g) whether the 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
 
  (h) any other terms of the debt securities.
 
(See Section 301.)
 
                                       8

 
Guarantee of Sempra Energy; Holding Company Structure
 
  Sempra Energy will unconditionally guarantee the payment of principal of and
any premium and interest on the debt securities issued by Sempra Energy
Holdings, when due and payable, whether at the stated maturity date, by
declaration of acceleration, call for redemption or otherwise, in accordance
with the terms of the debt securities and the indenture. These guarantees are
referred to as the "debt securities guarantees" in this prospectus. The debt
securities guarantees will remain in effect until the entire principal of and
any premium and interest on the debt securities has been paid in full or
otherwise discharged in accordance with the provisions of the indenture. (See
Article Fourteen.)
 
  Sempra Energy conducts its operations primarily through its subsidiaries and
substantially all of its consolidated assets are held by its subsidiaries.
Accordingly, Sempra Energy's cash flow and its ability to meet its obligations
under its debt securities and the debt securities guarantees are largely
dependent upon the earnings of its subsidiaries and the distribution or other
payment of these earnings to Sempra Energy in the form of dividends or loans or
advances and repayment of loans and advances from Sempra Energy. The
subsidiaries are separate and distinct legal entities and have no obligation to
pay any amounts due on the Sempra Energy debt securities or to make any funds
available for payment of amounts due on these debt securities or, except for
Sempra Energy Holdings, the debt securities guarantees.
 
  Because Sempra Energy is a holding company, its obligations under the debt
securities and the debt securities guarantees will be effectively subordinated
to all existing and future liabilities of its subsidiaries. Therefore, Sempra
Energy's rights and the rights of its creditors, including the rights of the
holders of the debt securities issued by Sempra Energy and any debt securities
guarantees, to participate in the assets of any subsidiary upon the liquidation
or reorganization of the subsidiary will be subject to the prior claims of the
subsidiary's creditors. To the extent that Sempra Energy may itself be a
creditor with recognized claims against any of its subsidiaries, Sempra
Energy's claims would still be effectively subordinated to any security
interest in, or mortgages or other liens on, the assets of the subsidiary and
would be subordinated to any indebtedness or other liabilities of the
subsidiary senior to that held by Sempra Energy. Although agreements to which
Sempra Energy and its subsidiaries are parties limit the incurrence of
additional indebtedness, both Sempra Energy and its subsidiaries retain the
ability to incur substantial additional indebtedness and other liabilities.
 
  In addition, Sempra Energy Holdings also conducts its operations primarily
through its subsidiaries and substantially all of its consolidated assets are
held by its subsidiaries. Accordingly, the discussion above is equally
applicable to Sempra Energy Holdings and the debt securities it issues.
 
Payment of Debt Securities--Interest
 
  Unless indicated differently in a prospectus supplement, we will pay interest
on the debt security on each interest payment date by check mailed to the
person in whose name the debt security is registered as of the close of
business on the regular record date relating to the interest payment date,
except that interest payable at stated maturity, upon redemption or otherwise,
will be paid to the person to whom principal is paid.
 
  However, if we default in paying interest on a debt security, we will pay
defaulted interest in either of the two following ways:
 
  (a) 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
 
                                       9

 
     entitled to the payment. The special record date will be between 10 and
     15 days before the payment date we propose. Finally, we will pay the
     defaulted interest on the payment date to the registered holder of the
     debt security as of the close of business on the special record date.
 
  (b) 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 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 Debt Securities--Principal
 
  Unless we indicate differently in a prospectus supplement, we will pay
principal of and any premium and interest on the debt securities at stated
maturity, upon redemption or otherwise, upon presentation of the debt
securities at the office of the trustee, as our paying agent. Any other paying
agent initially designated for the debt securities of a particular series will
be named in the applicable prospectus supplement.
 
  In our discretion, we may change the place of payment on the debt
securities, and may remove any paying agent and may appoint one or more
additional paying agents. (See Section 1002.)
 
Form; Transfers; Exchanges
 
  The debt securities will be issued
 
  (a) only in fully registered form;
 
  (b) without interest coupons; and
 
  (c) in denominations that are even multiples of $1,000.
 
  You may have your debt securities divided into debt securities of smaller
denominations (of at least $1,000) or combined into debt securities of larger
denominations, as long as the total principal amount is not changed. This is
called an "exchange."
 
  You may exchange or transfer debt securities at the office of the trustee.
The trustee acts as our agent for registering debt securities in the names of
holders and transferring 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.
 
  In our discretion, we may change the place for registration of transfer of
the 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 debt securities, but you
may be required to pay a sum sufficient to cover any tax or other governmental
charge payable in connection with the transfer or exchange. We may block the
transfer or exchange of (a) debt securities during a period of 15 days prior
to giving any notice of redemption or (b) any debt security selected for
redemption in whole or in part, except the unredeemed portion of any debt
security being redeemed in part. (See Section 305.)
 
                                      10

 
Redemption
 
  We will set forth any terms for the redemption of debt securities in a
prospectus supplement. Unless we indicate differently in a prospectus
supplement, and except with respect to debt securities redeemable at the option
of the registered holder, debt securities will be redeemable upon notice by
mail between 30 and 60 days prior to the redemption date. If less than all of
the debt securities of any series or any tranche of a series are to be
redeemed, the trustee will select the debt securities to be redeemed. In the
absence of any provision for selection, the trustee will choose a method of
random selection it deems fair and appropriate. (See Sections 1102, 1103 and
1104.)
 
  Debt securities will cease to bear interest on the redemption date. We will
pay the redemption price and any accrued interest once you surrender the debt
security for redemption. (See Section 1105.) If only part of a debt security is
redeemed, the trustee will deliver to you a new debt security of the same
series for the remaining portion without charge. (Section 1106.)
 
  We may make any redemption conditional upon the receipt by the paying agent,
on or prior to the date fixed for redemption, of money sufficient to pay the
redemption price. If the paying agent has not received the money by the date
fixed for redemption, we will not be required to redeem the debt securities.
(See Section 1104.)
 
Events of Default
 
  An "event of default" occurs with respect to debt securities of any series
if:
 
  (a) we do not pay any interest on any debt securities of the applicable
      series within 60 days of the due date;
 
  (b) we do not pay principal or premium on any debt securities of the
      applicable series on its due date;
 
  (c) we remain in breach of a covenant or warranty (excluding covenants and
      warranties solely applicable to a specific series) of the indenture for
      90 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 25% of the principal amount
      of debt securities of the affected series;
 
  (d) the debt securities guarantees on any series
 
    (1) cease to be effective (except in accordance with their terms),
 
    (2) are found in any judicial proceeding to be unenforceable or
        invalid, or
 
    (3) are denied or disaffirmed (except in accordance with their terms);
 
  (e) we file for bankruptcy or other specified events in bankruptcy,
      insolvency, receivership or reorganization occur; or
 
  (f) any other event of default specified in the prospectus supplement
      occurs.
 
(See Section 501.)
 
  No event of default with respect to a series of debt securities necessarily
constitutes an event of default with respect to the debt securities of any
other series issued under the indenture.
 
                                       11

 
Remedies
 
 Acceleration
 
  If an event of default occurs and is continuing with respect to any series of
debt securities, then either the trustee or the registered holders of 25% in
principal amount of the outstanding debt securities of that series may declare
the principal amount of all of the debt securities of that series to be due and
payable immediately. (See Section 502.)
 
 Rescission of Acceleration
 
  After the declaration of acceleration has been made 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
 
    (1) all overdue interest;
 
    (2) the principal of and any premium which have become due otherwise
        than by the declaration of acceleration and overdue interest on
        these amounts;
 
    (3) interest on overdue interest to the extent lawful;
 
    (4)  all amounts due to the trustee under the indenture; and
 
  (b) all events of default, other than the nonpayment of the principal 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
 
  Subject to the indenture, if an event of default with respect to the debt
securities of any one series occurs and is continuing, the registered holders
of a majority in principal amount of the outstanding debt securities of that
series will have the right to
 
  (a) direct the time, method and place of conducting any proceeding for any
      remedy available to the trustee, or
 
  (b) exercise any trust or power conferred on the trustee with respect to
      the debt securities of the series.
 
  If an event of default is continuing with respect to more than one series of
debt securities, the registered holders of a majority in aggregate principal
amount of the outstanding debt securities of all the series, considered as one
class, will have the right to make such direction, and not the registered
holders of the debt securities of any one of the series. These rights of
registered holders to make direction are subject to the following limitations:
 
  (a) the registered holders' directions will not conflict with any law or
      the indenture; and
 
  (b) the registered holders' directions may not involve the trustee in
      personal liability where the trustee believes indemnity is not
      adequate.
 
                                       12

 
  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 any debt
security will have any right to institute any proceeding, judicial or
otherwise, with respect to the indenture for the appointment of a receiver or
for any other remedy thereunder unless
 
  (a) that registered holder has previously given the trustee written notice
      of a continuing event of default;
 
  (b) the registered holders of 25% in aggregate principal amount of the
      outstanding debt securities of all affected series, considered as one
      class, 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
 
  (c) 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 debt securities of all affected series, considered as one
      class.
 
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. (See Sections 507 and 603.)
 
  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
Sections 507 and 508.)
 
Notice of Default
 
  The trustee is required to give the registered holders of the debt securities
notice of any default under the indenture to the extent required by the Trust
Indenture Act, unless the default has been cured or waived; except that in the
case of an event of default of the character specified above in clause (c)
under "Events of Default," no notice shall be given to the registered holders
until at least 75 days after the occurrence thereof. (See Section 602.) 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.
 
  We will furnish the trustee with an annual statement as to the compliance by
the company issuing the debt security 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 debt securities of any series may waive, on behalf of the
registered holders of all debt securities of the 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 debt security. (See Section 513.)
 
  Compliance with certain covenants in the indenture or otherwise provided with
respect to debt securities may be waived by the registered holders of a
majority in aggregate principal amount of the affected debt securities,
considered as one class. (See Section 1006.)
 
                                       13

 
Consolidation, Merger and Conveyance of Assets as an Entirety; No Financial
Covenants
 
  Subject to the provisions described in the next paragraph, each of Sempra
Energy and Sempra Energy Holdings will preserve its corporate existence. (See
Section 1004.)
 
  Sempra Energy and Sempra Energy Holdings have each agreed not to consolidate
with or merge into any other entity, and Sempra Energy has agreed not to
convey, transfer or lease its properties and assets substantially as an
entirety to any entity, unless:
 
  (a) the entity formed by the consolidation or into which Sempra Energy or
      Sempra Energy Holdings, as the case may be, is merged, or the entity
      which acquires or which leases the property and assets of Sempra Energy
      substantially as an entirety, is an entity 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 outstanding debt securities (or the debt securities guarantees
      endorsed thereon, as the case may be) and the performance of all of the
      covenants of Sempra Energy or Sempra Energy Holdings, as the case may
      be, under the indenture, and
 
  (b) immediately after giving effect to the transactions, no event of
      default, and no event which after notice or lapse of time or both would
      become an event of default, will have occurred and be continuing.
 
(See Section 801.)
 
  Neither the indenture nor the debt security guarantee contains any financial
or other similar restrictive covenants. Any such covenants with respect to any
particular series of debt securities will be set forth in the applicable
prospectus supplement.
 
Modification of Indenture
 
  Without Registered Holder Consent. Without the consent of any registered
holders of debt securities, we and the applicable trustee may enter into one or
more supplemental indentures for any of the following purposes:
 
  (a) to evidence the succession of another entity to Sempra Energy or Sempra
      Energy Holdings; or
 
  (b) to add one or more covenants of Sempra Energy or Sempra Energy Holdings
      or other provisions for the benefit of the registered holders of all or
      any series or tranche of debt securities, or to surrender any right or
      power conferred upon Sempra Energy or Sempra Energy Holdings; or
 
  (c) to add any additional events of default for all or any series of debt
      securities; or
 
  (d) to change or eliminate any provision of the indenture or to add any new
      provision to the indenture that does not adversely affect the interests
      of the registered holders; or
 
  (e) to provide security for the debt securities of any series; or
 
  (f) to establish the form or terms of debt securities of any series or
      tranche or any debt securities guarantees as permitted by the
      indenture; or
 
  (g) to provide for the issuance of bearer securities; or
 
                                       14

 
  (h) to evidence and provide for the acceptance of appointment of a separate
      or successor trustee; or
 
  (i) to provide for the procedures required to permit the utilization of a
      noncertificated system of registration for any series or tranche of
      debt securities; or
 
  (j) to change any place or places where
 
    (1) we may pay principal, premium and interest,
 
    (2) debt securities may be surrendered for transfer or exchange, or
 
    (3) notices and demands to or upon Sempra Energy or Sempra Energy
        Holdings may be served; or
 
  (k) to cure any ambiguity, defect or inconsistency or to make any other
      changes that do not adversely affect the interests of the registered
      holders in any material respect.
 
(See Section 901.)
 
  If the Trust Indenture Act is amended after the date of the indenture so as
to require changes to the indenture or so as to permit changes to, or the
elimination of, provisions which, at the date of the indenture or at any time
thereafter, were required by the Trust Indenture Act to be contained in the
indenture, the indenture will be deemed to have been amended so as to conform
to the amendment or to effect the changes or elimination, and Sempra Energy,
Sempra Energy Holdings and the applicable trustee may, without the consent of
any registered holders, enter into one or more supplemental indentures to
effect or evidence the amendment.
 
  With Registered Holder Consent. We and the trustee may, with some exceptions,
amend or modify any indenture with the consent of the registered holders of at
least a majority in aggregate principal amount of the debt securities of all
series affected by the amendment or modification (voting as one class).
However, no amendment or modification may, without the consent of the
registered holder of each outstanding debt security directly affected thereby,
 
  (a) change the stated maturity of the principal or interest on any debt
      security (other than pursuant to the terms thereof), or reduce the
      principal amount, interest or premium payable or change the currency in
      which any debt security is payable, or impair the right to bring suit
      to enforce any payment;
 
  (b) reduce the percentages of registered holders whose consent is required
      for any supplemental indenture or waiver or reduce the requirements for
      quorum and voting under the indenture; or
 
  (c) 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 registered holders of
debt securities of one or more particular series or tranches will be deemed not
to affect the rights under the indenture of the registered holders of debt
securities of any other series or tranche. (See Section 902.)
 
Miscellaneous Provisions
 
  The indenture provides that certain debt securities, including those for
which payment or redemption money has been deposited or set aside in trust as
described under "Satisfaction and
 
                                       15

 
Discharge" below, will not be deemed to be "outstanding" in determining whether
the registered holders of the requisite principal amount of the outstanding
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 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. If a record date is set for any
action to be taken by registered holders of particular debt securities, the
action may be taken only by persons who are registered holders of the
respective debt securities on the record date. (See Section 104.)
 
Defeasance and Covenant Defeasance
 
  The indentures provide, unless the terms of the particular series of debt
securities provide otherwise, that we may, upon satisfying several conditions,
cause ourselves to be:
 
  (a) discharged from our obligations, with some exceptions, with respect to
      any series of debt securities, which we refer to as "defeasance"; and
 
  (b) released from our obligations under certain covenants with respect to
      any series of debt securities, which we refer to as "covenant
      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 moneys to pay the principal of and any premium and interest on those
debt securities on the maturity dates of the payments or upon redemption.
 
  The indentures permit defeasance with respect to any series of debt
securities even if a prior covenant defeasance has occurred with respect to the
debt securities of that series. Following a defeasance, payment of the debt
securities defeased may not be accelerated because of an event of default.
Following a covenant defeasance, payment of the debt securities may not be
accelerated by reference to the covenants described in the description of
covenant defeasance above. However, if such an acceleration were to occur, the
realizable value at the acceleration date of the money and government
obligations in the defeasance trust could be less than the principal and
interest then due on the respective debt securities, since the required deposit
in the defeasance trust would be based upon scheduled cash flows rather than
market value, which would vary depending upon interest rates and other factors.
 
  Under current United States federal income tax law, the defeasance
contemplated in the preceding paragraphs would be treated as an exchange of the
relevant debt securities in which holders of the debt securities might
recognize gain or loss. In addition, the amount, timing and character of
amounts that holders would be required thereafter to include in income might be
different from that which would be includible in the absence of such
defeasance. Prospective investors are urged to consult their own tax advisors
as to the specific consequences of a defeasance, including the applicability
and effect of tax laws other than United States federal income tax laws.
 
                                       16

 
  Under current United States federal income tax laws, unless accompanied by
other changes in the terms of the debt securities, covenant defeasance should
not be treated as a taxable exchange.
 
Resignation and Removal of the Trustee; Deemed Resignation
 
  The trustee may resign at any time by giving written notice to us.
 
  The trustee may also be removed by act of the registered holders of a
majority in principal amount of the then outstanding debt securities of any
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 and if the
successor accepts, the trustee will be deemed to have resigned.
 
  (Section 610).
 
Subordination
 
  Unless we indicate differently in a prospectus supplement, any subordinated
debt securities will be subordinated in the following manner. If Sempra
Energy's assets are distributed upon our dissolution, winding up, liquidation
or reorganization, the payment of the principal of (and premium, if any) and
interest on any subordinated debt securities will be subordinated, to the
extent provided in the subordinated debt security indenture and the applicable
supplemental indenture, to the prior payment in full of all senior
indebtedness, including senior debt securities. However, Sempra Energy's
obligation to pay principal (and premium, if any) or interest on the
subordinated debt securities will not otherwise be affected. No payment on
account of principal (or premium, if any), sinking fund or interest may be made
on the subordinated debt securities at any time when there is a default in the
payment of principal, premium, if any, sinking fund or interest on senior
indebtedness. If, while Sempra Energy is in default on senior indebtedness, any
payment is received by the trustee under the subordinated debt security
indenture or the holders of any of the subordinated debt securities before it
has paid all senior indebtedness in full, the payment or distribution must be
paid over to the holders of the unpaid senior indebtedness or applied to the
repayment of the unpaid senior indebtedness. Subject to paying the senior
indebtedness in full, the holders of the subordinated debt securities will be
subrogated to the rights of the holders of the senior indebtedness to the
extent that payments are made to the holders of senior indebtedness out of the
distributive share of the subordinated debt securities.
 
  Due to the subordination, if Sempra Energy's assets are distributed upon
insolvency, certain of its general creditors may recover more, ratably, than
holders of subordinated debt securities. The subordinated debt security
indenture or applicable supplemental indenture may state that its subordination
provisions will not apply to money and securities held in trust under the
satisfaction and discharge, and the legal defeasance provisions of the
subordinated debt security indenture.
 
  If this prospectus is being delivered in connection with the offering of a
series of subordinated debt securities, the accompanying prospectus supplement
or the information incorporated by reference in it will set forth the
approximate amount of senior indebtedness outstanding as of a recent date.
 
                                       17

 
Conversion Rights
 
  The terms and conditions of any debt securities being offered that are
convertible into common stock of Sempra Energy will be set forth in a
prospectus supplement. These terms will include the conversion price, the
conversion period, provisions as to whether conversion will be at the option of
the holder or us, the events requiring an adjustment of the conversion price
and provisions affecting conversion in the event that the debt securities are
redeemed.
 
Governing Law
 
  Each indenture and the related debt securities will be governed by and
construed in accordance with the laws of the State of New York.
 
                                       18

 
                         DESCRIPTION OF SEMPRA ENERGY'S

  The following description of Sempra Energy's common stock and preferred stock
is only a summary and is qualified in its entirety by reference to the articles
of incorporation and bylaws of Sempra Energy. Therefore, you should read
carefully the more detailed provisions of Sempra Energy's Amended and Restated
Articles of Incorporation, Sempra Energy's Amended and Restated Bylaws, and
Sempra Energy's Rights Agreement, dated May 26, 1998, between Sempra Energy and
First Chicago Trust Company of New York, as rights agent, copies of which are
incorporated by reference as exhibits to the registration statement of which
this prospectus is a part.

  The authorized capital stock of Sempra Energy consists of (1) 750,000,000
shares of Sempra Energy common stock, without par value, and (2) 50,000,000
shares of preferred stock, without par value. As of February 27, 1999, there

stock are authorized under the Sempra Energy articles of incorporation. The
issued and outstanding shares of Sempra Energy common stock are duly
authorized, validly issued, fully paid, nonassessable and free of preemptive
rights.
 
Sempra Energy Common Stock
 
  The holders of Sempra Energy common stock are entitled to receive such
dividends as the Sempra Energy board of directors may from time to time
declare, subject to any rights of holders of outstanding shares of Sempra
Energy preferred stock. Except as otherwise provided by law, each holder of
Sempra Energy common stock is entitled to one vote per share on each matter
submitted to a vote of a meeting of shareholders, subject to any class or
series voting rights of holders of Sempra Energy preferred stock. Under the
Sempra Energy articles of incorporation, the Sempra Energy board of directors
is classified into three classes each consisting of a number as nearly equal as
possible to one-third of the total number of directors constituting the entire
Sempra Energy board of directors. The holders of shares of Sempra Energy common
stock are not entitled to cumulate votes for the election of directors.
 
  In the event of any liquidation, dissolution or winding up of Sempra Energy,
whether voluntary or involuntary, the holders of shares of Sempra Energy common
stock, subject to any rights of the holders of outstanding shares of Sempra
Energy preferred stock, are entitled to receive any remaining assets of Sempra
Energy after the discharge of its liabilities.
 
  Holders of Sempra Energy common stock are not entitled to preemptive rights
to subscribe for or purchase any part of any new or additional issue of stock
or securities convertible into stock. Sempra Energy common stock does not
contain any redemption provisions or conversion rights and is not liable to
assessment or further call.
 
  Each outstanding share of Sempra Energy common stock is accompanied by a
right to purchase one one-hundredth of a share of Class A Junior Participating
Preferred Stock, without par value, of Sempra Energy at a price of $80.00 per
right, subject to certain anti-dilution adjustments. The Sempra Energy board of
directors has reserved 7,500,000 shares of such Class A
preferred stock for issuance upon exercise of the rights, as more fully
discussed below under the heading "--Description of Preferred Share Purchase
Rights."
 
                                       19

 
  The registrar and transfer agent for the Sempra Energy common stock is First
Chicago Trust Company of New York.
 
Preferred Stock
 
  The Sempra Energy board of directors is authorized, pursuant to the Sempra
Energy articles of incorporation, to issue up to 50,000,000 shares of Sempra
Energy preferred stock in one or more series and to fix and determine the
number of shares of preferred stock of any series, to determine the designation
of any such series, to increase or decrease the number of shares of any such
series subsequent to the issue of shares of that series, and to determine or
alter the rights, preferences, privileges and restrictions granted to or
imposed upon any such series. Currently there are no shares of Sempra Energy
preferred stock outstanding. However, the Sempra Energy board of directors has
reserved 7,500,000 shares of Class A preferred stock for issuance in connection
with rights issued under the Sempra Energy rights agreement.
 
  Prior to the issuance of shares of each series of preferred stock, the board
of directors is required to adopt resolutions and file a certificate of
determination with the Secretary of State of the State of California. The
certificate of determination will fix for each series the designation and
number of shares and the rights, preferences, privileges and restrictions of
the shares including, but not limited to, the following:
 
  (a) the title and stated value of the preferred stock;
 
  (b) voting rights, if any, of the preferred stock;
 
  (c) any rights and terms of redemption (including sinking fund provisions);
 
  (d) the dividend rate(s), period(s) and/or payment date(s) or method(s) of
      calculation applicable to the preferred stock;
 
  (e) whether dividends are cumulative or non-cumulative and, if cumulative,
      the date from which dividends on the preferred stock will accumulate;
 
  (f) the relative ranking and preferences of the preferred stock as to
      dividend rights and rights upon the liquidation, dissolution or winding
      up of our affairs;
 
  (g) the terms and conditions, if applicable, upon which the preferred stock
      will be convertible into common stock, including the conversion price
      (or manner of calculation) and conversion period;
 
  (h) the provision for redemption, if applicable, of the preferred stock;
 
  (i) the provisions for a sinking fund, if any, for the preferred stock;
 
  (j) liquidation preferences;
 
  (k) any limitations on issuance of any class or series of preferred stock
      ranking senior to or on a parity with the class or series of preferred
      stock as to dividend rights and rights upon liquidation, dissolution or
      winding up of our affairs; and
 
  (l) any other specific terms, preferences, rights, limitations or
      restrictions of the preferred stock.
 
  All shares of preferred stock will, when issued, be fully paid and
nonassessable and will not have any preemptive or similar rights.
 
                                       20

 
  In addition to the terms listed above, we will set forth in a prospectus
supplement the following terms relating to the class or series of preferred
stock being offered:
 
  (a) the number of shares of the preferred stock offered, the liquidation
      preference per share and the offering price of the preferred stock;
 
  (b) the procedures for any auction and remarketing, if any, for the
      preferred stock;
 
  (c) any listing of the preferred stock on any securities exchange; and
 
  (d) a discussion of any material and/or special United States federal
      income tax considerations applicable to the preferred stock.
 
 
Rank
 
  Unless we specify otherwise in the applicable prospectus supplement, the
preferred stock will rank, with respect to dividends and upon our liquidation,
dissolution or winding up:
 
  (a) senior to all classes or series of our common stock and to all of our
      equity securities ranking junior to the preferred stock;
 
  (b) on a parity with all of our equity securities the terms of which
      specifically provide that the equity securities rank on a parity with
      the preferred stock; and
 
  (c) junior to all of our equity securities the terms of which specifically
      provide that the equity securities rank senior to the preferred stock.
 
Description of Preferred Share Purchase Rights
 
  On May 26, 1998, the Sempra Energy board of directors adopted a preferred
share purchase rights plan providing that one preferred share purchase right
will attach to each share of Sempra Energy common stock. The description and
terms of the rights are set forth in a rights agreement, dated as of May 26,
1998, by and between Sempra Energy and First Chicago Trust Company of New York,
as rights agent. The purchase rights have an anti-takeover effect that is
intended to discourage coercive or unfair takeover tactics and to encourage any
potential acquirer to negotiate a fair price to all Sempra Energy shareholders.
The purchase rights may cause substantial dilution to any party that may
attempt to acquire Sempra Energy on terms not approved by the Sempra Energy
board of directors. However, the purchase rights are structured in a way so as
not to interfere with any negotiated merger or other business combination. The
rights will expire on May 31, 2008. Until a right is exercised, the holder of
the right will have no rights as a shareholder of Sempra Energy beyond those
rights afforded to existing shareholders, including the right to vote or to
receive dividends.
 
  The rights are designed to assure that all of Sempra Energy's shareholders
receive fair and equal treatment in the event of any proposed takeover of
Sempra Energy and to guard against partial tender offers, open market
accumulations and other abusive tactics that may be deployed to gain control of
Sempra Energy without a control premium paid to all shareholders. Any time
prior to the first date that a person or group has become an "acquiring person"
as defined in the rights agreement, the rights should not interfere with any
merger or other business combination as long as it is approved by the Sempra
Energy board of directors.
 
                                       21

 
Anti-Takeover Provisions
 
  The Sempra Energy articles of incorporation and bylaws contain provisions
that may have the effect of discouraging persons from acquiring large blocks of
Sempra Energy stock or delaying or preventing a change in control of Sempra
Energy. The material provisions which may have such an effect are:
 
  (a) classification of the Sempra Energy board of directors into three
      classes with the term of only one class expiring each year;
 
  (b) a provision permitting the Sempra Energy board of directors to make,
      amend or repeal the Sempra Energy bylaws;
 
  (c) authorization for the Sempra Energy board of directors to issue Sempra
      Energy preferred stock in series and to fix rights and preferences of
      the series (including, among other things, whether, and to what extent,
      the shares of any series will have voting rights and the extent of the
      preferences of the shares of any series with respect to dividends and
      other matters);
 
  (d) a provision that shareholders may take action only at annual or special
      meetings or by unanimous written consent in lieu of a meeting;
 
  (e) advance notice procedures with respect to nominations of directors or
      proposal other than those adopted or recommended by the Sempra Energy
      board of directors; and
 
  (f) provisions permitting amendment of certain of these provisions only by
      an affirmative vote of the holders of at least two-thirds of the
      outstanding shares of Sempra Energy common stock entitled to vote.
 
  Some acquisitions of Sempra Energy's outstanding voting shares would also
require approval of the SEC under the Public Utility Holding Company Act of
1935 and of various state and foreign regulatory authorities.

                      DESCRIPTION OF PREFERRED SECURITIES
 
General
 
  Each Declaration authorizes the regular trustees to issue on behalf of each
trust one series of preferred securities which will have the terms described in
a prospectus supplement. The proceeds from the sale of a trust's preferred and
common securities will be used by the trust to purchase a series of
subordinated debt securities issued by Sempra Energy. The subordinated debt
securities will be held in trust by the property trustee for the benefit of the
holders of the preferred and common securities.
 
  Under each preferred securities guarantee, Sempra Energy will agree to make
payments of distributions and payments on redemption or liquidation with
respect to a trust's preferred securities, but only to the extent the trust has
funds available to make those payments and has not made the payments. See
"Description of Preferred Securities Guarantees."
 
  The assets of a trust available for distribution to the holders of its
preferred securities will be limited to payments from Sempra Energy under the
series of subordinated debt securities held by the trust. If Sempra Energy
fails to make a payment on the subordinated debt securities, the trust will not
have sufficient funds to make related payments, including distributions, on its
preferred securities.
 
  Each preferred securities guarantee, when taken together with Sempra Energy's
obligations under the related series of subordinated debt securities, the
subordinated indenture and the related Declaration, will provide a full and
unconditional guarantee of amounts due on the preferred securities issued by a
trust.
 
  Each Declaration will be qualified as an indenture under the Trust Indenture
Act. Each property trustee will act as indenture trustee for the preferred
securities to be issued by the applicable trust, in order to comply with the
provisions of the Trust Indenture Act.
 
  Each series of preferred securities will have the terms, including
distributions, redemption, voting, liquidation rights and the other preferred,
deferred or other special rights or other restrictions as described in the
relevant Declaration or made part of the Declaration by the Trust Indenture Act
or the Delaware Business Trust Act. The terms of the preferred securities will
mirror the terms of the subordinated debt securities held by the trust.
 
  The prospectus supplement relating to the preferred securities of a trust
will describe the specific terms of the preferred securities, including:
 
  (a) the name of the preferred securities;
 
  (b) the dollar amount and number of securities issued;
 
  (c) any provision relating to deferral of distribution payments;
 
  (d) the annual distribution rate(s) (or method of determining the rate(s)),
      the payment date(s) and the record dates used to determine the holders
      who are to receive distributions;
 
  (e) the date from which distributions shall be cumulative;
 
  (f) the optional redemption provisions, if any, including the prices, time
      periods and other terms and conditions for which the preferred
      securities shall be purchased or redeemed, in whole or in part;
 
                                       23

 
  (g) the terms and conditions, if any, upon which the applicable series of
      subordinated debt securities may be distributed to holders of the
      preferred securities;
 
  (h) the voting rights, if any, of holders of the preferred securities;
 
  (i) any securities exchange on which the preferred securities will be
      listed;
 
  (j) whether the preferred securities are to be issued in book-entry form
      and represented by one or more global certificates and, if so, the
      depository for the global certificates and the specific terms of the
      depositary arrangements; and
 
  (k) any other relevant rights, preferences, privileges, limitations or
      restrictions of the preferred securities.
 
  Each prospectus supplement will describe certain United States federal income
tax considerations applicable to the purchase, holding and disposition of the
series of preferred securities covered by the prospectus supplement.
 
Liquidation Distribution Upon Dissolution
 
  Unless otherwise specified in an applicable prospectus supplement, each
Declaration states that the related trust shall be dissolved:
 
  (a) on the expiration of the term of the trust;
 
  (b) upon the bankruptcy of Sempra Energy;
 
  (c) upon the filing of a certificate of dissolution or its equivalent with
      respect to Sempra Energy;
 
  (d) after obtaining the consent of at least a majority in liquidation
      amount of the preferred and common securities of the trust, voting
      together as a single class;
 
  (e) 90 days after the revocation of the articles of incorporation of Sempra
      Energy (but only if the articles of incorporation are not reinstated
      during that 90-day period);
 
  (f) upon the distribution of the related subordinated debt securities
      directly to the holders of the preferred and common securities of the
      trust;
 
  (g) upon the redemption of all of the common and preferred securities of
      the trust; or
 
  (h) upon entry of a court order for the dissolution of Sempra Energy, or
      the trust.
 
  Unless otherwise specified in an applicable prospectus supplement, in the
event of a dissolution, after the trust satisfies (whether by payment or
reasonable provision for payment) all amounts owed to creditors, the holders of
the preferred and common securities will be entitled to receive:
 
  (a) cash equal to the aggregate liquidation amount of each preferred and
      common security specified in an accompanying prospectus supplement,
      plus accumulated and unpaid distributions to the date of payment;
      unless
 
  (b) subordinated debt securities in an aggregate principal amount equal to
      the aggregate liquidation amount of the preferred and common securities
      are distributed to the holders of the preferred and common securities.
 
                                       24

 
  If the trust cannot pay the full amount due on its preferred and common
securities because insufficient assets are available for payment, then the
amounts payable by the trust on its preferred and common securities shall be
paid pro rata. However, if an event of default under the related Declaration
has occurred, the total amounts due on the preferred securities will be paid
before any distribution on the common securities.
 
Declaration Events of Default
 
  An event of default under the subordinated indenture relating to a series of
subordinated debt securities is an event of default under the Declaration of
the trust that owns these subordinated debt securities (a "Declaration event of
default"). See "Description of Debt Securities--Events of Default."
 
  Sempra Energy and the regular trustees of a trust must file annually with the
property trustee for the trust a certificate stating whether or not they are in
compliance with all the applicable conditions and covenants under the related
Declaration.
 
  Upon the occurrence of a Declaration event of default, the property trustee
of the applicable trust, as the sole holder of the subordinated debt securities
held by the trust, will have the right under the subordinated indenture to
declare the principal of, premium, if any, and interest on the subordinated
debt securities to be immediately due and payable.
 
  If a property trustee fails to enforce its rights under the related
Declaration or the subordinated indenture, any holder of the preferred
securities issued by the related trust may, to the fullest extent permitted by
law and subject to the terms of the Declaration and the subordinated indenture,
sue Sempra Energy, or seek other remedies, to enforce the property trustee's
rights under the Declaration or the subordinated indenture without first
instituting a legal proceeding against the property trustee or any other
person.
 
  If Sempra Energy fails to pay principal, premium, if any, or interest on a
series of subordinated debt securities when payable, then a holder of the
related preferred securities issued by a trust which owns the notes may
directly sue Sempra Energy or seek other remedies to collect its pro rata share
of payments owed.
 
Consolidation, Merger or Amalgamation of the Trusts
 
  A trust may not consolidate, amalgamate, merge with or into, convert into, or
be replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other corporation or other body ("Merger
Event"), except as described below or as described in "Liquidation Distribution
Upon Dissolution." A trust may, with the consent of a majority of its regular
trustees and without the consent of the holders of its preferred and common
securities, consolidate, amalgamate, merge with or into, convert into, or be
replaced by another trust, if:
 
  (a) the successor entity either
 
    (1) assumes all of the obligations of the trust relating to its
        preferred and common securities; or
 
    (2) substitutes for the trust's preferred and common securities other
        securities substantially similar to the preferred and common
        securities ("successor securities"), so long as the successor
        securities rank the same as the preferred and common securities for
        distributions and payments upon liquidation, redemption and
        otherwise;
 
                                       25

 
  (b) Sempra Energy acknowledges a trustee of the successor entity who has
      the same powers and duties as the property trustee of the trust as the
      holder of the particular series of subordinated debt securities;
 
  (c) the preferred securities are listed, or any successor securities will
      be listed, upon notice of issuance, on the same national securities
      exchange or other organization that the preferred securities are then
      listed;
 
  (d) the Merger Event does not cause its preferred securities or successor
      securities to be downgraded by any national rating agency;
 
  (e) the Merger Event does not adversely affect the rights, preferences and
      privileges of the holders of its preferred and common securities or
      successor securities in any material way (other than with respect to
      any dilution of the holders' interest in the new entity);
 
  (f) the successor entity has a purpose substantially identical to that of
      the trust;
 
  (g) prior to the Merger Event, Sempra Energy has received an opinion of
      counsel from a nationally recognized law firm stating that:
 
    (1) the Merger Event does not adversely affect the rights of the
        holders of the trust's preferred securities or any successor
        securities in any material way (other than with respect to any
        dilution of the holders' interest in the new entity); and
 
    (2) following the Merger Event, neither the trust nor the successor
        entity will be required to register as an investment company under
        the Investment Company Act of 1940, as amended; and
 
  (h) Sempra Energy guarantees the obligations of the successor entity under
      the successor securities in the same manner as in the applicable
      preferred securities guarantee and the guarantee of the common
      securities for the trust.
 
  In addition, unless all of the holders of the preferred and common securities
approve otherwise, a trust shall not consolidate, amalgamate, merge with or
into, convert into, or be replaced by any other entity or permit any other
entity to consolidate, amalgamate, merge with or into, or replace it, if the
transaction would cause the trust or the successor entity to be classified
other than as a grantor trust for United States federal income tax purposes.
 
Voting Rights; Amendment of Declarations
 
  The holders of preferred securities have no voting rights except as discussed
under "--Consolidation, Merger or Amalgamation of the Trusts" and "Description
of the Preferred Securities Guarantees--Amendments and Assignment," and as
otherwise required by law and the Declaration for the trust.
 
  A Declaration may be amended if approved by a majority of the regular
trustees of the applicable trust. However, if any proposed amendment provides
for, or the regular trustees otherwise propose to effect:
 
  (a) any action that would adversely affect the powers, preferences or
      special rights of the trust's preferred and common securities, whether
      by way of amendment to the Declaration or otherwise; or
 
  (b) the dissolution, winding-up or termination of the trust other than
      pursuant to the terms of its Declaration,
 
                                       26

 
then the holders of the trust's preferred and common securities as a single
class will be entitled to vote on the amendment or proposal. In that case, the
amendment or proposal will be effective only if approved by at least a majority
in liquidation amount of the preferred and common securities affected by the
amendment or proposal.
 
  If any amendment or proposal referred to in clause (a) above would adversely
affect only the preferred securities or the common securities of a trust, then
only the affected class will be entitled to vote on the amendment or proposal
and the amendment or proposal will only be effective with the approval of at
least a majority in liquidation amount of the affected class.
 
  No amendment may be made to a Declaration if the amendment would:
 
  (a) cause the related trust to be characterized as other than a grantor
      trust for United States federal income tax purposes;
 
  (b) adversely affect the powers, liabilities or duties of the property
      trustee or the Delaware trustee; or
 
  (c) cause the related trust to be deemed to be an "investment company"
      which is required to be registered under the Investment Company Act.
 
  The holders of a majority in aggregate liquidation amount of the preferred
securities of each trust have the right to:
 
  (a) direct the time, method and place of conducting any proceeding for any
      remedy available to the property trustee of the trust; or
 
  (b) direct the exercise of any trust or power conferred upon the property
      trustee under that trust's Declaration, including the right to direct
      the property trustee, as the holder of a series of subordinated debt
      securities, to:
 
    (1) exercise the remedies available under the subordinated indenture
        with respect to the subordinated debt securities;
 
    (2) waive any event of default under the subordinated indenture that is
        waivable; or
 
    (3) cancel an acceleration of the principal of the subordinated debt
        securities.
 
  However, if the subordinated indenture requires the consent of the holders of
more than a majority in aggregate principal amount of a series of subordinated
debt securities (a "super-majority"), then the property trustee for the series
must get approval of the holders of a super-majority in liquidation amount of
the series of preferred securities.
 
  In addition, before taking any of the foregoing actions, the property trustee
must obtain an opinion of counsel stating that, as a result of the action, the
trust will continue to be classified as a grantor trust for United States
federal income tax purposes.
 
  The property trustee of a trust will notify all preferred securities holders
of the trust of any notice received from the trustee of the subordinated
indenture with respect to the subordinated debt securities held by the trust.
 
                                       27

 
  As described in each Declaration, the property trustee may hold a meeting to
have preferred securities holders vote on a change or have them approve the
change by written consent.
 
  If a vote of preferred securities holders is taken or a consent is obtained,
any preferred securities that are owned by Sempra Energy or any of its
affiliates will, for purposes of the vote or consent, be treated as if they
were not outstanding. This means:
 
  (a) Sempra Energy and any of its affiliates will not be able to vote on or
      consent to matters requiring the vote or consent of holders of
      preferred securities; and
 
  (b) any preferred securities owned by Sempra Energy or any of its
      affiliates will not be counted in determining whether the required
      percentage of votes or consents has been obtained.
 
Removal and Replacement of Trustees
 
  Only the holder of a trust's common securities has the right to remove, or
replace the regular trustees and, prior to an event of default, property and
Delaware trustees of the trust. If an event of default occurs, only the holders
of a trust's preferred securities have the right to remove or replace the
property and Delaware trustees. The resignation or removal of any trustee and
the appointment of a successor trustee shall be effective only on the
acceptance of appointment by the successor trustee in accordance with the
provisions of the Declaration for the trust.
 
Information Concerning the Property Trustees
 
  For matters relating to compliance with the Trust Indenture Act, the property
trustee of each trust will have all of the duties and responsibilities of an
indenture trustee under the Trust Indenture Act. Each property trustee, other
than during the occurrence and continuance of a Declaration event of default
under the applicable trust, undertakes to perform only the duties as are
specifically set forth in the applicable Declaration and, upon a Declaration
event of default, must use the same degree of care and skill as a prudent
person would exercise or use in the conduct of his or her own affairs. Subject
to this provision, a property trustee is under no obligation to exercise any of
the powers given it by the applicable Declaration at the request of any holder
of preferred securities unless it is offered reasonable security or indemnity
against the costs, expenses and liabilities that it might incur. However, the
holders of the preferred securities will not be required to offer an indemnity
where the holders, by exercising their voting rights, direct the property
trustee to take any action following a Declaration event of default.
 
Miscellaneous
 
  The regular trustees of each trust are authorized and directed to conduct the
affairs of and to operate the trust in such a way that:
 
  (a) it will not be deemed to be an "investment company" required to be
      registered under the Investment Company Act;
 
  (b) it will be classified as a grantor trust for United States federal
      income tax purposes; and
 
  (c) the subordinated debt securities held by it will be treated as
      indebtedness of Sempra Energy for United States federal income tax
      purposes.
 
  Sempra Energy and the regular trustees of a trust are authorized to take any
action (so long as it is consistent with applicable law or the applicable
certificate of trust or Declaration) that Sempra Energy and the regular
trustees of the trust determine to be necessary or desirable for such purposes.
 
                                       28

 
  Registered holders of preferred securities have no preemptive or similar
rights.
 
  A trust may not borrow money, issue debt, execute mortgages or pledge any of
its assets.
 
Governing Law
 
  Each Declaration and the related preferred securities will be governed by and
construed in accordance with the laws of the State of Delaware.
 
                                       29

 
                 DESCRIPTION OF PREFERRED SECURITIES GUARANTEES
 
General
 
  Sempra Energy will execute a preferred securities guarantee, which benefits
the holders of preferred securities, at the time that a trust issues those
preferred securities. Each preferred securities guarantee will be qualified as
an indenture under the Trust Indenture Act. The Bank of New York will act as
indenture trustee ("preferred securities guarantee trustee") under each
preferred securities guarantee for the purposes of compliance with the Trust
Indenture Act.
 
  The preferred securities guarantee trustee will hold each preferred
securities guarantee for the benefit of the preferred securities holders of the
applicable trust.
 
  Sempra Energy will irrevocably agree, as described in each preferred
securities guarantee, to pay in full, to the holders of the preferred
securities issued by the applicable trust, the preferred securities guarantee
payments (as defined below) (except to the extent previously paid), when and as
due, regardless of any defense, right of set-off or counterclaim which the
trust may have or assert. The following payments, to the extent not paid by a
trust ("preferred securities guarantee payments"), will be covered by the
applicable preferred securities guarantee:
 
    (a) any accrued and unpaid distributions required to be paid on the
  applicable preferred securities, to the extent that the trust has funds
  available to make the payment;
 
    (b) the redemption price, to the extent that the trust has funds
  available to make the payment; and
 
    (c) upon a voluntary or involuntary dissolution and liquidation of the
  trust (other than in connection with a distribution of subordinated debt
  securities to holders of the preferred securities or the redemption of all
  the preferred securities), the lesser of:
 
      (1) the aggregate of the liquidation amount specified in the
    prospectus supplement for each preferred security plus all accrued and
    unpaid distributions on the preferred security to the date of payment,
    to the extent the trust has funds available to make the payment; and
 
      (2) the amount of assets of the trust remaining available for
    distribution to holders of its preferred securities upon a dissolution
    and liquidation of the trust.
 
  Sempra Energy's obligation to make a preferred securities guarantee payment
may be satisfied by directly paying the required amounts to the holders of the
preferred securities or by causing the trust to pay the amounts to the holders.
 
  No single document executed by Sempra Energy relating to the issuance of
preferred securities will provide for its full, irrevocable and unconditional
guarantee of the preferred securities. It is only the combined operation of
Sempra Energy's obligations under the subordinated indenture, the subordinated
debt securities and the applicable preferred securities guarantee and
Declaration that has the effect of providing a full, irrevocable and
unconditional guarantee of a trust's obligations under its preferred
securities.
 
                                       30

 
Status of the Preferred Securities Guarantees
 
  Each preferred securities guarantee will constitute an unsecured obligation
of Sempra Energy and will rank:
 
    (a) subordinate and junior in right of payment to all of Sempra Energy's
  other liabilities (except any guarantee now or hereafter issued by Sempra
  Energy in respect of any preferred or preference stock of any of its
  affiliates);
 
    (b) equal with any guarantee now or hereafter issued by Sempra Energy in
  respect of the most senior preferred or preference stock now or hereafter
  issued by Sempra Energy, and with any guarantee now or hereafter issued by
  it in respect of any preferred or preference stock of any of its
  affiliates; and
 
    (c) senior to Sempra Energy's common stock.
 
  Each Declaration will require that the holder of preferred securities accept
the subordination provisions and other terms of the preferred securities
guarantee. Each preferred securities guarantee will constitute a guarantee of
payment and not of collection (in other words the holder of the guaranteed
security may sue Sempra Energy, or seek other remedies, to enforce its rights
under the preferred securities guarantee without first suing any other person
or entity). A preferred securities guarantee will not be discharged except by
payment of the preferred securities guarantee payments in full to the extent
not previously paid or upon distribution to the applicable preferred securities
holders of the corresponding series of subordinated debt securities pursuant to
the appropriate Declaration.
 
Amendments and Assignment
 
  Except with respect to any changes which do not adversely affect the rights
of holders of a series of preferred securities in any material respect (in
which case no consent of the holders will be required), a preferred securities
guarantee may be amended only with the prior approval of the holders of at
least a majority in aggregate liquidation amount of the preferred securities
(excluding any the preferred securities held by Sempra Energy or any of its
affiliates). A description of the way to obtain any approval is described under
"Description of the Preferred Securities--Voting Rights; Amendment of
Declarations." All guarantees and agreements contained in a preferred
securities guarantee will be binding on Sempra Energy's successors, assigns,
receivers, trustees and representatives and are for the benefit of the holders
of the applicable preferred securities.
 
Preferred Securities Guarantee Events of Default
 
  An event of default under a preferred securities guarantee occurs if Sempra
Energy fails to make any of its required payments or perform its obligations
under the preferred securities guarantee.
 
  The holders of at least a majority in aggregate liquidation amount of the
preferred securities relating to each preferred securities guarantee (excluding
any preferred securities held by Sempra Energy or any of its affiliates) will
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the preferred securities guarantee
trustee relating to the preferred securities guarantee or to direct the
exercise of any trust or power given to the preferred securities guarantee
trustee under the preferred securities guarantee.
 
                                       31

 
Information Concerning the Preferred Securities Guarantee Trustees
 
  The preferred securities guarantee trustee under a preferred securities
guarantee, other than during the occurrence and continuance of a default under
the preferred securities guarantee, will perform only the duties that are
specifically described in the preferred securities guarantee. After such a
default, the preferred securities guarantee trustee will exercise the same
degree of care and skill as a prudent person would exercise or use in the
conduct of his or her own affairs. Subject to this provision, a preferred
securities guarantee trustee is under no obligation to exercise any of its
powers as described in the applicable preferred securities guarantee at the
request of any holder of covered preferred securities unless it is offered
reasonable indemnity against the costs, expenses and liabilities that it might
incur.
 
Termination of the Preferred Securities Guarantees
 
  Each preferred securities guarantee will terminate once the applicable
preferred securities are paid in full or upon distribution of the corresponding
series of subordinated debt securities to the holders of the preferred
securities. Each preferred securities guarantee will continue to be effective
or will be reinstated if at any time any holder of preferred securities issued
by the applicable trust must restore payment of any sums paid under the
preferred securities or the preferred securities guarantee.
 
Governing Law
 
  The preferred securities guarantees will be governed by and construed in
accordance with the laws of the State of New York.
 
Relationship Among Preferred Securities, Preferred Securities Guarantees and
Subordinated Debt Securities Held By Each Trust
 
  Payments of distributions and redemption and liquidation payments due on each
series of preferred securities (to the extent the applicable trust has funds
available for the payments) will be guaranteed by Sempra Energy to the extent
described under "Description of the Preferred Securities Guarantees." No single
document executed by Sempra Energy in connection with the issuance of any
series of preferred securities will provide for its full, irrevocable and
unconditional guarantee of the preferred securities. It is only the combined
operation of Sempra Energy's obligations under the applicable preferred
securities guarantee, Declaration, subordinated indenture and subordinated debt
securities that has the effect of providing a full, irrevocable and
unconditional guarantee of a trust's obligations under its preferred
securities.
 
  As long as Sempra Energy makes payments of interest and other payments when
due on the subordinated debt securities held by a trust, the payments will be
sufficient to cover the payment of distributions and redemption and liquidation
payments due on the preferred securities issued by that trust, primarily
because:
 
    (a) the aggregate principal amount of the subordinated debt securities
  will be equal to the sum of the aggregate liquidation amount of the
  preferred and common securities;
 
    (b) the interest rate and interest and other payment dates on the
  subordinated debt securities will match the distribution rate and
  distribution and other payment dates for the preferred securities;
 
                                       32

 
    (c) Sempra Energy shall pay for any and all costs, expenses and
  liabilities of each trust except the trust's obligations under its
  preferred securities (and Sempra Energy has agreed to guarantee such
  payment); and
 
    (d) each Declaration provides that the related trust will not engage in
  any activity that is not consistent with the limited purposes of the trust.
 
  If and to the extent that Sempra Energy does not make payments on the
subordinated debt securities, the trust will not have funds available to make
payments of distributions or other amounts due on its preferred securities. In
those circumstances, you will not be able to rely upon the preferred securities
guarantee for payment of these amounts. Instead, you may directly sue Sempra
Energy or seek other remedies to collect your pro rata share of payments owed.
If you sue Sempra Energy to collect payment, then Sempra Energy will assume
your rights as a holder of preferred securities under the trust's Declaration
to the extent Sempra Energy makes a payment to you in any legal action.
 
  A holder of any preferred security may sue Sempra Energy, or seek other
remedies, to enforce its rights under the applicable preferred securities
guarantee without first suing the applicable preferred securities guarantee
trustee, the trust which issued the preferred security or any other person or
entity.

                              PLAN OF DISTRIBUTION
 
  We may sell the securities described in this prospectus from time to time in
one or more transactions
 
    (a) to purchasers directly;
 
    (b) to underwriters for public offering and sale by them;
 
    (c) through agents;
 
    (d) through dealers; or
 
                                       33

 
    (e) through a combination of any of the foregoing methods of sale.
 
  We may distribute the securities from time to time in one or more
transactions at:
 
    (a) a fixed price or prices, which may be changed;
 
    (b) market prices prevailing at the time of sale;
 
    (c) prices related to such prevailing market prices; or
 
    (d) negotiated prices.
 
 Direct Sales
 
  We may sell the securities directly to institutional investors or others who
may be deemed to be underwriters within the meaning of the Securities Act with
respect to any resale of the securities. A prospectus supplement will describe
the terms of any sale of securities we are offering hereunder.
 
 To Underwriters
 
  The applicable prospectus supplement will name any underwriter involved in a
sale of securities. 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 securities in the form of underwriting discounts or
commissions and may also receive commissions from purchasers of securities for
whom they may act as agent. Credit Suisse First Boston Corporation, Goldman,
Sachs & Co., Merrill Lynch & Co., Morgan Stanley Dean Witter and Salomon Smith
Barney Inc. may be involved in any at the market offering of equity securities
by or on our behalf.
 
  Underwriters may sell securities 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 securities will be subject to certain conditions
precedent, and the underwriters will be obligated to purchase all the
securities if any are purchased.
 
 Through Agents and Dealers
 
  We will name any agent involved in a sale of securities, 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 securities being offered pursuant
to their prospectus, we will sell the securities to the dealer, as principal.
The dealer may then resell the securities to the public at varying prices to be
determined by the dealer at the time of resale.
 
                                       34

 
 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 the securities 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 securities, 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 securities
may be deemed to be underwriters as defined in 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 securities on any securities exchange. The securities will be a new issue
of securities with no established trading market. Any underwriters that
purchase securities for public offering and sale may make a market in such
securities, 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 securities.

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 Sempra Energy Amended and Restated Articles of
Incorporation and the Amended and Restated 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 Sempra Energy shall
be allowed, subject to certain limitations, in excess of the indemnification
otherwise permissible under California law. In addition, Sempra Energy and
Sempra Energy Holdings have indemnification agreements with each of their
officers and directors that provide for indemnification for monetary damages to
the fullest extent permissible under California law. Sempra Energy and Sempra
Energy Holdings maintain liability insurance and are also insured against loss
for which they may be required or permitted by law to indemnify their directors
and officers for their related acts.
 
  The directors and officers of Sempra Energy and Sempra Energy Holdings 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 Sempra Energy or Sempra Energy Holdings.
 
  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.

*To be filed by amendment or incorporated by reference in connection with the
offering of the securities.
 
Item 17. Undertakings.
 
  The undersigned registrants hereby undertake:
 
  (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 dated 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 registrants pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the Registration Statement.
 
                                      II-3

 
  (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 which remain unsold at the termination of the
offering.
 
  (4) That, for purposes of determining any liability under the Securities Act,
each filing of Sempra Energy'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 trustees 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.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrants pursuant to the provisions described under Item 15 above, or
otherwise, the registrants have 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 a 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, such 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.
