                         ANNUAL MEETING OF SHAREHOLDERS
                         ------------------------------
                         PROXY STATEMENT AND PROSPECTUS      
    
         This Proxy Statement and Prospectus is being furnished to shareholders
      (the "Shareholders") of San Diego Gas & Electric Company, a California
      corporation ("SDG&E" or the "Company"), in connection with the
      solicitation of proxies by the SDG&E Board of Directors (the "Board of
      Directors"). The proxies will be voted at the Annual Meeting of
      Shareholders to be held at 11:00 a.m. on Tuesday, April 25, 1995, at the
      California Center for the Arts, Escondido, 340 North Escondido Boulevard,
      Escondido, California, and at any adjournment or postponement thereof (the
      "Annual Meeting"), for the purposes listed in the preceding Notice of
      Annual Meeting.     
    
         At the Annual Meeting, the Shareholders will be asked to approve, among
      other things, the implementation of a holding company structure for SDG&E
      and a related agreement of merger (the "Merger Agreement") among SDG&E,
      SDO Parent Co., Inc., a California corporation formed by SDG&E
      ("ParentCo"), and San Diego Merger Company, a California corporation
      formed by ParentCo ("MergeCo"). At the time of the Merger (defined below),
      ParentCo will be a wholly owned subsidiary of SDG&E and MergeCo will be a
      wholly owned subsidiary of ParentCo. Pursuant to the Merger Agreement, 
      MergeCo will merge with and into SDG&E (the "Merger") and each outstanding
      share of the common stock of SDG&E, without par value ("SDG&E Common
      Stock"), will be automatically converted into one share of the common
      stock of ParentCo, without par value ("ParentCo Common Stock"). As a
      result, SDG&E will become a subsidiary of ParentCo and the holders of
      SDG&E Common Stock will become holders of ParentCo Common Stock. The
      outstanding shares of SDG&E's cumulative preferred stock, $20 par value
      per share ("SDG&E Cumulative Preferred Stock"), and SDG&E's preference
      stock (cumulative), without par value ("SDG&E Preference Stock
      (Cumulative)"), will be unchanged and will continue to be outstanding
      shares of SDG&E. See "Item No. 2 - Formation of a Holding Company
      Structure" under the heading "Plan of Implementation." The name "SDO
      Parent Co., Inc." is subject to change at the discretion of the Board of
      Directors and without further action by the Shareholders prior to
      consummation of the Merger.     
    
         This Proxy Statement and Prospectus also serves as the Prospectus for
      ParentCo under the Securities Act of 1933 with respect to the issuance of
      up to 116,541,000 shares of ParentCo Common Stock in connection with the
      Merger. Further information concerning the stock offered hereby is
      contained in "Item No. 2 - Formation of a Holding Company Structure" under
      the heading "Articles of Incorporation and Bylaws of ParentCo."     
    
         The approximate date of mailing of this Proxy Statement and Prospectus
      is March 10, 1995.     
    
      THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
      AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE
      SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
      PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY
      REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

         This Proxy Statement is also a Prospectus delivered in compliance with
      the Securities Act of 1933, as amended (the "Securities Act"). A
      registration statement under the Securities Act has been filed with the
      Securities and Exchange Commission (the "SEC"), Washington, D.C., with

      Holding Company Structure," and if such applications are accepted Exchange
      Act reports, proxy statements and other information concerning ParentCo
      will be available for inspection and copying at such exchanges.

                          SUMMARY OF PROXY STATEMENT
                          --------------------------
    
         The following summary of the matters to be voted on at the Annual
      Meeting of Shareholders is qualified in its entirety by reference to the
      more detailed information set forth elsewhere herein, including the
      exhibits hereto and the documents incorporated herein by reference.      

    
                       ITEM NO. 1 - ELECTION OF DIRECTORS      
                       ----------------------------------
    
        Ten persons have been nominated for election as Directors of SDG&E.
      Each of the nominees is currently serving as a Director of SDG&E (as well
      as a Director of ParentCo).  If the proposed formation of a holding
      company structure for SDG&E described below is approved and implemented,
      each of the Directors of SDG&E will also be ratified as a Director of
      ParentCo.      

    
             ITEM NO. 2 - FORMATION OF A HOLDING COMPANY STRUCTURE      
             -----------------------------------------------------

      SDG&E
    
         SDG&E is an operating public utility primarily engaged in the business
      of providing (i) electric service to customers in San Diego County and the
      southern portion of Orange County and (ii) gas to customers in San Diego
      County. SDG&E's principal executive offices are located at 101 Ash Street,
      San Diego, California 92101 (telephone number: (619) 696-2000) (mailing
      address: P.O. Box 1831, San Diego, California 92112-4150).      

      ParentCo
    
         ParentCo, the proposed holding company for SDG&E, was organized by
      SDG&E for the purpose of becoming the new parent holding company. Its
      principal executive offices are at the same location as SDG&E's offices
      referred to above (it also shares the same telephone number and mailing
      address).     

      Reasons for the Restructuring

         The SDG&E Board of Directors considers it to be in the best interests
      of SDG&E and its Shareholders to change the corporate structure of SDG&E
      and its subsidiaries. The objective of such a restructuring is to have
      SDG&E and its direct subsidiaries become separate, directly-owned
      subsidiaries of a new parent company (ParentCo), with the present holders
      of SDG&E Common Stock becoming holders of ParentCo Common Stock. The Board
      of Directors believes the proposed restructuring will provide the means
      for a more clearly defined separation of utility and non-utility
      operations and permit greater financial and organizational flexibility to
      meet the changing operational, regulatory and economic environment for
      utilities.

         The proposed restructuring will lead to a change for holders of SDG&E
      Common Stock in the nature of their investment: from shares of stock in a
      regulated utility with some diversified operations

                                       v
<PAGE>
 
    
      in separate subsidiaries to shares of stock in a holding company which is
      not directly regulated in the same manner as a utility. SDG&E will
      constitute the predominant part of ParentCo's earning power and assets for
      the foreseeable future. However, both regulation of utilities and the
      markets which SDG&E has traditionally served are changing. As facets of
      the traditional utility business which were once regulated, such as
      electric generation, have become less regulated and more competitive, the
      energy options for customers, particularly large industrial users of
      energy, are expanding.      
    
         Management believes that the corporate separation afforded by a holding
      company structure will permit the holding company, ParentCo, to respond
      effectively to increasing competition in the energy business. Where a
      facet of the business becomes unregulated, that facet can be separated
      from the core utility business of SDG&E, although remaining under the
      common ownership of ParentCo. Separation of such facets of the energy
      business, as well as the diversified operations of SDG&E's present non-
      utility subsidiaries, from the core utility business of SDG&E will help to
      protect SDG&E's stability as viewed by sources of financing. Such
      stability is vital to avoid increased capital costs for SDG&E, and thus
      higher utility rates. Accordingly, the holding company structure will
      support SDG&E's ability to continue efficiently meeting its customers
      needs while permitting ParentCo to respond to a changing business
      environment. See "Item No. 2 - Formation of a Holding Company Structure--
      Reasons for the Restructuring."      

      Accomplishing the Restructuring

         Pursuant to the Merger Agreement in the form attached to this Proxy
      Statement and Prospectus as Exhibit A, a subsidiary of ParentCo (MergeCo)
      will be merged with and into SDG&E. In the Merger, the outstanding shares
      of SDG&E Common Stock will be converted into new shares of ParentCo Common
      Stock on a share-for-share basis, and SDG&E will become a subsidiary of
      ParentCo. SDG&E Cumulative Preferred Stock and SDG&E Preference Stock
      (Cumulative) will remain outstanding, and be unaffected by the Merger.
    
         If the actions contemplated by the Merger Agreement are approved by the
      Shareholders, it is contemplated that the Merger will become effective as
      soon as practicable following receipt of all required regulatory approvals
      in respect of the Merger and related restructuring, including approval by
      the California Public Utilities Commission (the "CPUC"). An application
      for such approval by the CPUC was filed by SDG&E on November 7, 1994.     
    
         Following the Merger, SDG&E's interest in its direct subsidiaries will
      be transferred to ParentCo (the transfer and the Merger are sometimes
      referred to as the "restructuring"). The restructuring will be accounted
      for in a manner similar to a pooling of interests.      

         If the restructuring is completed, it will not be necessary to exchange
      certificates representing SDG&E Common Stock for certificates representing
      ParentCo Common Stock. Rather, certificates for SDG&E Common Stock will
      automatically be deemed to represent certificates for a like number of
      shares of ParentCo Common Stock.

                                      vi
<PAGE>
 
         Application has been made to list ParentCo Common Stock on the New York
      Stock Exchange (the "NYSE") and on the Pacific Stock Exchange. In the
      absence of such listing on the NYSE, the Board of Directors may elect not
      to consummate the transactions contemplated by the Merger Agreement
      (including the Merger).

      Regulatory Approvals
    
         SDG&E must obtain certain authorizations from the CPUC, the Federal
      Energy Regulatory Commission and the Nuclear Regulatory Commission to
      implement various aspects of the restructuring. See "Item No. 2 -
      Formation of a Holding Company Structure--Regulation."      

      Dividend Policy
    
         It is expected that ParentCo initially will make quarterly dividend
      payments on ParentCo Common Stock equal to the rate currently paid by
      SDG&E on SDG&E Common Stock and on approximately the same schedule of
      dates as that now followed by SDG&E. Future dividend payments initially
      will depend primarily on the earnings, financial condition and capital
      requirements of SDG&E. See "Item No. 2 - Formation of a Holding Company
      Structure--Dividend Policy."     

      Federal Income Tax Consequences
    
         The proposed restructuring should not affect the position of present
      SDG&E shareholders for federal income tax purposes. See "Item No. 2 -
      Formation of a Holding Company Structure--Federal Income Tax Consequences
      of the Merger."      

      Vote Required to Approve the Restructuring

         Shareholder approval of the restructuring will require the favorable
      vote of:

         1. A majority of the outstanding shares of SDG&E Common Stock;

         2. A majority of the outstanding shares of SDG&E Common Stock and SDG&E
            Cumulative Preferred Stock, voting together, with each share of
            SDG&E Common Stock having one vote and each share of SDG&E
            Cumulative Preferred Stock having two votes; and
    
         3. Two-thirds of the outstanding shares of SDG&E Cumulative Preferred
            Stock and SDG&E Preference Stock (Cumulative), voting together, with
            each share having one vote. See "Item No. 2 - Formation of a Holding
            Company Structure--Required Vote."     

         SDG&E's Directors and executive officers and their affiliates own less
      than one percent (1%) of the voting securities of SDG&E.  After the
      restructuring, they will continue to own less than one percent (1%) of the
      voting securities of ParentCo.

      Rights of Dissenting Shareholders
    
         Holders of SDG&E Cumulative Preferred Stock, 4.60% Series, upon
      compliance with certain statutory requirements, will be entitled to
      receive payment of the fair market value of their shares if the Merger is
      completed. Holders of SDG&E Common Stock and holders of SDG&E Cumulative
      Preferred Stock other than the 4.60% Series who comply with the statutory
      requirements also may be entitled to receive payment of the fair market
      value of their shares if the Merger is completed; however, they will not
      be so entitled unless (i) five percent (5%) or more of the shares of their
      class (with SDG&E Common Stock, as one class, and SDG&E Cumulative
      Preferred Stock other than the 4.60% Series, as another class) demand
      payment or (ii) their shares are restricted as to transfer. Holders of
      SDG&E Preference Stock (Cumulative) have no statutory right to dissent and
      receive payment for their shares in connection with the Merger. See "Item
      No. 2 - Formation of a Holding Company Structure--Rights of Dissenting
      Shareholders."

      enclosed with this Proxy Statement and Prospectus, contains audited
      financial statements of SDG&E as of December 31, 1994 and for the year

                      ITEM NO. 3 - AMENDMENT OF 1986 LTIP      
                      -----------------------------------
    
         On October 24, 1994, the Board of Directors amended, restated and
      extended SDG&E's 1986 Long-Term Incentive Plan (the "LTIP") subject to
      approval by the Shareholders at the Annual Meeting to: (i) permit
      incentive stock options under Section 422 of the Internal Revenue Code of
      1986, as amended (the "Code") to be granted from the shares subject to the
      LTIP; (ii) extend the term until April 24, 2005; (iii) include technical
      changes to conform the LTIP to certain deductibility requirements of
      Section 162(m) of the Code and to Rule 16b-3 under the Securities Exchange
      Act of 1934, as amended; (iv) add provisions for the automatic grant of
      300 shares of SDG&E Common Stock per year to each non-employee Director
      (to become shares of ParentCo Common Stock if the proposed formation of a
      holding company structure for SDG&E is approved and implemented); and (v)
      make certain other, technical changes.      
    
         These changes will be effective upon their approval by the
      Shareholders.  The amendment, restatement and extension of the LTIP does
      not increase the number of shares available for grant under the LTIP above
      the number previously approved by the Shareholders.

      No. 4 - Shareholder Proposal" below for further discussion regarding this

                              GENERAL INFORMATION      
                              -------------------


      Meeting Date; Voting; Proxies
    
         The enclosed proxy is solicited by the Board of Directors (the "Board
      of Directors") of San Diego Gas & Electric Company ("SDG&E" or the
      "Company") from the shareholders of SDG&E (the "Shareholders") for use at
      the Annual Meeting of Shareholders, together with any adjournment or
      postponement thereof (the "Annual Meeting"), to be held at 11:00 a.m. on
      Tuesday, April 25, 1995, at the California Center for the Arts, Escondido,
      340 North Escondido Boulevard, Escondido, California. Mail to SDG&E should
      be addressed to the Office of the Secretary, P.O. Box 1831, San Diego,
      California 92112-4150.     
    
         The enclosed proxy may be revoked at any time before it is voted by
      filing a written notice of revocation with SDG&E or by presenting an
      executed proxy bearing a later date at or prior to the Annual Meeting. A
      Shareholder also may revoke a proxy by attending the Annual Meeting and
      voting in person; however, attendance at the Annual Meeting will not in
      and of itself constitute revocation of a proxy.     
    
         The Board of Directors has fixed the close of business on March 1, 1995
      as the record date (the "Record Date") for the determination of
      Shareholders entitled to notice of and to vote at the Annual Meeting.     
 
         SDG&E has three classes of stock, of which there were issued and
      outstanding at the close of business on the Record Date the following:
    
         (a)  116,531,735 shares of common stock, without par value ("SDG&E
              Common Stock");     

         (b)  1,374,650 shares of cumulative preferred stock, $20 par value per
              share ("SDG&E Cumulative Preferred Stock"); and

         (c)  3,190,000 shares of preference stock (cumulative), without par
              value ("SDG&E Preference Stock (Cumulative)").

                                       1
<PAGE>
 
    
      A Shareholder of record as of the close of business on the Record Date is
      entitled to one vote per share for each share of SDG&E Common Stock held
      and two votes per share for each share of SDG&E Cumulative Preferred Stock
      held. Holders of SDG&E Preference Stock (Cumulative) have voting rights
      only in limited circumstances described in the SDG&E Restated Articles of
      Incorporation (the "SDG&E Restated Articles"), and as allowed by
      California law.     
    
         Shares represented by properly executed proxies received by SDG&E
      prior to or at the Annual Meeting will be voted at the Annual Meeting in
      accordance with the instructions specified in each proxy.  If no
      instructions are specified in a particular proxy, subject shares will be
      voted (i) "FOR" the election of the nominees of the Board of Directors for
      directorships, unless authority to vote is withheld as provided in the
      proxy, (ii) "FOR" approval of the Merger Agreement (defined below under
      "Item No. 2 - Formation of a Holding Company Structure--Plan of
      Implementation") and the proposed formation of a holding company structure
      for SDG&E, (iii) "FOR" the proposal to amend the 1986 Long-Term Incentive
      Plan (the "LTIP"), and (iv) "AGAINST" the shareholder proposal.  In the
      event that any other matters properly come before the Annual Meeting, the
      holders of proxies solicited by the Board of Directors will vote on those
      matters in accordance with their judgment, and discretionary authority to
      do so is included in the proxy.     
    
         This Proxy Statement and Prospectus and the enclosed proxy were first
      mailed on or about March 10, 1995 to Shareholders entitled to vote at the
      Annual Meeting.     

    
                       ITEM NO. 1 - ELECTION OF DIRECTORS 
                       ----------------------------------
      (Item 1 on Common Stock and Cumulative Preferred Stock Proxy Cards)     

    
         The full Board of Directors is to be elected at the Annual Meeting to
      serve until the end of the ensuing 12-month period (or until their
      successors are duly elected and qualified).  The ten candidates nominated
      to serve on the Board of Directors receiving the highest number of
      affirmative votes shall be elected to the Board of Directors.  If the
      proposed formation of a holding company structure for SDG&E is approved
      and implemented, each of the Directors of SDG&E will also be ratified as a
      Director of the parent holding company, to serve for the terms provided in
      such corporation's charter documents.  See "Item No. 2 - Formation of a
      Holding Company Structure--Articles of Incorporation and Bylaws of
      ParentCo, and --Elections: Classified Board of Directors" below.     

                                       2
<PAGE>
 
    
         The persons named in the enclosed proxy card will vote the number of
      shares shown thereon.  Proxies given to the persons named will be voted
      "FOR" the election of all nominees listed below, unless authority to vote
      is withheld with respect to one or more nominees.  All of the nominees are
      presently Directors of SDG&E (as well as Directors of the corporation
      which is proposed for Shareholder approval as the parent holding company)
      and, with the exception of Messrs. Jones and Stickel, have been elected
      previously by the Shareholders.  Should any of the nominees become
      unavailable (an event which is not anticipated), and the size of the Board
      of Directors is not reduced accordingly, proxies will be voted for the
      remainder of the listed nominees and for such other nominees as may be
      designated by the present Board of Directors as replacements for those who
      become unavailable.     
    
         Shares represented by proxies in which authority to vote is "WITHHELD"
      with respect to one or more nominees will be counted in the number of
      votes cast but will not be counted as votes for or against any nominee. If
      a broker or other nominee holding shares for a beneficial owner does not
      vote in the election of Directors, the shares will not be counted in the
      number of votes cast.     
    
      THE BOARD RECOMMENDS THE ELECTION OF THE BOARD'S NOMINEES FOR DIRECTORS.

          shares/$920,748; S. L. Baum, 19,810 shares/$331,818; D. E. Felsinger,
          15,595 shares/$261,216; N. A. Peterson, 8,980 shares/$150,415; and G.
          D. Cotton, 11,695 shares/$195,891.  The value      

                                       11
<PAGE>
 
    
          of the aggregate restricted stock holdings at December 31, 1994 is
          determined by multiplying $19.25, the fair market value of SDG&E's
          Common Stock on December 31, 1994, less the purchase price of $2.50
          per share, by the number of shares held. These December 31, 1994 share
          amounts include the [March 1], 1995 share amounts shown in "Security
          Ownership of Management and Certain Beneficial Holders" above. In
          certain instances, the [March 1], 1995 amounts are less due to the
          vesting of certain shares in January 1995. Regular quarterly dividends
          are paid on restricted stock held by these individuals, when declared
          by SDG&E.      
    
      (F) All other compensation includes a cash amount paid to each officer
          designated solely for the purpose of paying (a) the premium for an
          insurance policy providing death benefits equal to two times such
          officer's current compensation; such cash amount includes a gross-up
          payment such that the net amount retained by each officer, after
          deduction for any income tax imposed on such payment, will be equal to
          the gross amount which would have been paid to such officer had the
          income tax not been imposed; (b) SDG&E match under deferred
          compensation agreements which allow officers who have exceeded the
          maximum pretax amount under the Savings Plan to continue to make
          pretax deferrals of base compensation to an account in their name up
          to a maximum of 15%; up to 6% of base compensation will be matched by
          an SDG&E contribution of 50 cents per dollar deferred; no amount can
          be deferred by an officer or matched by SDG&E under this agreement
          until the officer contributes to the Savings Plan the maximum amount
          allowed by the tax law; and (c) SDG&E contributions to the Savings
          Plan. The respective amounts paid in fiscal year 1994 for each of the
          above officers were: T. A. Page, $44,096, $14,010, and $1,972; S. L.
          Baum, $11,125, $5,502 and $1,979; D. E. Felsinger, $8,475, $3,950 and
          $1,678; N. A. Peterson, $-0-, $-0- and $-0-; and G. D. Cotton, $9,297,
          $2,085 and $3,480.      

    
      Compensation of Directors      
    
         During 1994, Directors not holding salaried positions in SDG&E were 
      paid an annual retainer of $30,000, payable at the rate of $2,500 per
      month. No additional fees were paid for attendance at any meeting of the
      Board or of any committee of the Board. Non-employee Directors are
      reimbursed for their out-of-pocket expenses incurred to attend meetings.
      All Directors except Mr. Page are non-salaried Directors.      
    
         A proposal is included with this Proxy Statement and Prospectus which
      would add provisions to the LTIP for the automatic grant of 300 shares of
      SDG&E common stock per year to non-employee Directors (to become shares of
      parent holding company common stock if the proposed formation of a holding
      company structure for SDG&E is approved and implemented). See "Item No. 
      3 - Amendment of 1986 LTIP" below.      
    
         D. W. Derbes and T. A. Page are Directors of SDG&E who are also 
      directors of PDC and Wahlco Environmental. As a non-employee director, D.
      W. Derbes receives a $500 fee for attending each meeting of PDC. D. W.
      Derbes also receives an annual retainer of $12,000 plus a $1,000 fee for
      attending each meeting of Wahlco Environmental.     
    
         Mr. Page received no fees or other compensation for serving as a 
      Director of SDG&E or any of its subsidiaries.      
    
         Directors may elect to defer their retainers and/or fees for periods of
      time they select.      
    
         On December 17, 1990, the Board adopted a Retirement Plan for Directors
      applicable to Directors serving on the Board on or after such date. If a
      Director has at least five years of total Board service, then, beginning 
      in the calendar quarter following the later of the Director's      

                                       12
<PAGE>
 
    
      retirement from the Board or attaining age 65, the Director (or a
      surviving spouse) will receive during each subsequent 12-month period, a
      benefit amount equal to the Director's annual retainer (currently $30,000)
      for a benefit period equal to the number of years of the Director's total
      service on the Board. The benefit will end upon the completion of the
      benefit period or the death of the later to die of the Director and a
      surviving spouse, whichever occurs first. In computing the benefit period,
      periods of service as an employee Director shall be disregarded.      
    
      Employment Contract of Mr. Page      
    
         On September 12, 1988, Thomas A. Page and SDG&E entered into an
      employment agreement dated as of June 15, 1988. Mr. Page's employment
      agreement provides that he will serve as Chief Executive Officer and
      Chairman of the Board of Directors of SDG&E for a period of two years
      beginning June 15, 1988, subject to automatic extensions for successive
      two-year periods (unless the contract is terminated as described below)
      and that he will receive a salary at a rate of not less than $31,916.66
      per month or such greater amount as may, from time to time, be determined
      by the Board.      
    
         The employment agreement also provides that Mr. Page will be entitled
      to participation in the Executive Incentive Compensation Plan, any other
      annual bonus plan, the Savings Plan, the LTIP and any other long-term
      incentive plan. In addition, Mr. Page is entitled to participate in the
      Supplemental Executive Retirement Plan (the "SERP") and the Pension Plan.
      Pursuant to an earlier agreement between Mr. Page and SDG&E, Mr. Page was
      credited with years of service under the Pension Plan and the SERP equal
      to his years of service with SDG&E plus five extra years.      
    
         Under the employment agreement, if Mr. Page's employment is terminated
      (i) by the Board upon two years' written notice, (ii) upon his death or
      permanent disability, (iii) by SDG&E for cause or (iv) by Mr. Page upon 30
      days written notice to SDG&E, which termination is other than a
      "Constructive Termination" (as defined below), he will receive benefits
      through the last day of his term of employment and no additional benefits.
      If Mr. Page's employment is terminated (i) because of the dissolution,
      liquidation or winding-up of SDG&E, (ii) by a majority vote of the SDG&E
      Board of Directors without cause upon 30 days written notice or (iii) by
      Mr. Page as a result of (A) any violation of the compensation provisions
      of the employment agreement, (B) any adverse and significant change in Mr.
      Page's position, duties, responsibilities or status, including the failure
      to be elected to the Board and as Chief Executive Officer of SDG&E or (C)
      a change in Mr. Page's normal business location to a point away from
      SDG&E's main headquarters (each, a Constructive Termination), he will be
      entitled to two years' salary paid in a lump sum plus a bonus equal to
      200% of the average of the three highest bonuses paid to him during the
      previous five years, continued health and life insurance benefits under
      various plans, his SERP benefit (without regard to the limit described
      therein relating to Section 280G of the Internal Revenue Code of 1986, as
      amended (the "Code")) and his LTIP benefit. If any of the payments set
      forth in the previous sentence become subject to the excise tax imposed by
      Section 4999 of the Code, SDG&E will pay Mr. Page an additional amount
      such that the net amount retained by Mr. Page after deduction for such
      excise tax and any income and excise tax imposed on such additional amount
      will be equal to the gross amount which would have been paid to Mr. Page
      under the agreement had the excise tax not been      

                                       13

      imposed. The benefits payable to Mr. Page under the agreement on account
      of a change in control are in lieu of any benefits which would have
      otherwise been payable to Mr. Page under the Executive Severance Allowance
      Plan. The term "change in control" includes such significant events as
      those described under "Pension Plan and Supplemental Executive Retirement
      Plan" below.

/(A)/ The value (target) of the restricted stock awards is determined by 
      multiplying $19.875, the fair market value of SDG&E Common Stock on the
      date of grant, December 6, 1994, less the purchase price of $2.50 per
      share, by the number of shares awarded.     
    
/(B)/ The payout amounts set forth in this column represent both the maximum
      and the target amounts payable upon achievement of all performance-
      vesting goals. The minimum payout upon failure to achieve any of the
      performance vesting goals would be $0. The actual payout will depend upon
      the achievement of performance-vesting goals and upon the fair market
      value of SDG&E Common Stock at the date of vesting.     
    
/(C)/ Special grants of 2,500 shares each were made in 1994 to S. L. Baum
      and D. E. Felsinger. Lifting of restrictions on these shares is dependent
      upon Company performance in 1996 (discussed below).     
    
    The LTIP provides that the Executive Compensation Committee may grant 
to certain executives any combination of nonqualified stock options, incentive
stock options, restricted stock, stock appreciation rights, performance awards,
stock payments or dividend equivalents. As of December 31, 1994, all grants made
under the LTIP have been in the form of restricted stock.      

                                       14
<PAGE>
 
    
        With respect to LTIP shares purchased in 1986 through 1989, all
      restrictions have been lifted in prior years.      
    
        With respect to LTIP shares purchased in 1990, 1991, 1992, 1993 and
      1994, restrictions on one-quarter of the number of shares originally
      placed in escrow are to be released and the shares are to be delivered to
      the executives for each of the four succeeding calendar years if SDG&E's
      earnings per share meet or exceed the earnings per share target set by the
      Executive Compensation Committee or if, at the end of the first, second
      and third quarters of the following year, earnings for the twelve months
      then ending equal or exceed the weighted average of the targets for the
      prior year and the current year.  In addition, as to shares purchased in
      1990, 1991 and 1992, the restrictions on all remaining shares that are not
      released in such manner will be released and the shares will be delivered
      to executives at the end of the fourth succeeding calendar year, if and
      only if, a total return to Shareholders goal, as determined by the
      Executive Compensation Committee or the Board, is met.  Shares purchased
      in 1993 have no end-of-term goal.  As to shares purchased in 1994, the
      restrictions on all remaining shares may be released by the Board of
      Directors after considering the impact on 1995 - 1998 earnings of industry
      and corporate restructuring during such period.      
    
        In addition to the above-described restricted shares with four-year
      performance period-based restrictions, a special grant of 2,500 shares was
      made to each of S. L. Baum and D. E. Felsinger in 1994.  The restrictions
      on these shares are to be lifted at the end of 1996 if the Company meets
      or exceeds the target earnings per share for 1996 as set by the Executive
      Compensation Committee.  Such target earnings may be adjusted to reflect
      industry and corporate restructuring.      
    
        With respect to LTIP shares purchased in 1990, the total return to
      Shareholders goal as set by the Board of Directors for the four-year
      period ending in 1994 was met, the restrictions have been lifted and all
      shares have been delivered to the executives.  However, since the one-year
      earnings per share goal was not met at year-end 1994, the shares issued in
      1991, 1992 and 1993 which could have been released in 1994 are still held
      in escrow.      
    
        In general, restricted shares may not be sold, transferred or pledged
      until restrictions are removed or expire.  Purchasers of restricted stock
      have voting rights and will receive dividends prior to the time the
      restrictions lapse if and to the extent paid on SDG&E Common Stock
      generally.      
    
        All shares of restricted stock purchased are placed in escrow.  It is
      anticipated that restricted stock would be forfeited and would be resold
      to SDG&E at original cost in the event that vesting is not achieved by
      virtue of performance or other criteria.      
    
        Under the LTIP, all outstanding incentive awards become fully vested and
      exercisable without restrictions upon the occurrence of one of two events
      after a change in control.  The first triggering event is the failure of a
      successor corporation or its parent or subsidiary to make adequate
      provision for continuation of the LTIP by substituting new awards.  In the
      second triggering event, even if adequate provision for continuation of
      the LTIP and substitution of new awards has been made, an executive's
      incentive awards will become vested and exercisable if      

                                       15
<PAGE>
 
    
      the executive is terminated within three years after a change of control
      for reasons other than cause, retirement, death or disability, or
      voluntarily terminates employment due to adverse circumstances.      
    
        The term "change in control" includes such significant events as those
      described under "Pension Plan and Supplemental Executive Retirement Plan"
      below.  The adverse circumstances allowing such voluntary termination of
      employment consist of significant and adverse changes in the executive's
      position, duties, responsibilities or status, or the reduction or
      elimination of the executive's compensation or incentive compensation
      opportunities.      
    
        The LTIP will expire in January 1996, unless terminated by the Board
      prior to that date; however, a proposal is included in this Proxy
      Statement and Prospectus which, if approved by the Shareholders, would
      extend the term of the LTIP until April 24, 2005 (see "Item No. 3 -
      Amendment of 1986 LTIP" below).  Outstanding incentive awards will not be
      affected by such expiration or termination and will vest or be forfeited
      in accordance with their terms.

         In addition to the Pension Plan, the Supplemental Executive Retirement
      Plan (SERP) provides a supplemental retirement benefit for certain
      executives.  The aggregate monthly benefit payable under the combined
      Pension Plan and SERP to an executive who retires at age 62 and has
      completed at least five years of service will be a percentage of the
      executive's final pay equal to 5% times years of service (up to a maximum
      of 10 years); however, officers appointed prior to July 1, 1994 shall
      receive 6% times years of service (up to a maximum of 10 years).  Final
      pay is defined in the SERP as the monthly base pay rate in effect during
      the month immediately preceding retirement, plus 1/12 of the average of
      the highest three years' gross bonus awards.  Alternatively, the executive
      may elect to receive a lump sum cash payment equal to the actuarially
      determined present value of the monthly benefits.  The SERP      

                                       16
<PAGE>
 
    
      also provides reduced benefits to executives who retire between the ages
      of 55 and 61, if the executive has completed at least five years of
      employee service. Benefits may be paid also to executives who retire after
      age 62.      
    
         The above table shows the aggregate annual retirement benefits payable
      to executives under the Pension Plan and the SERP, assuming a straight
      life annuity form of pension at the normal retirement age of 62 for
      specified compensation and years of service.  The benefit amounts listed
      in the table are not subject to a deduction for Social Security benefits.
      SERP payments will be reduced by benefits payable under the Pension Plan.
     
     
         The SERP, as amended, provides monthly surviving spouse benefits equal
      to 50% of the defined benefits and disability benefits equal to 100% of
      the defined benefits.      
    
         The SERP also provides enhanced benefits to an executive who is
      adversely affected within three years after the occurrence of an event
      constituting a change in control of SDG&E.  If, during that period, an
      executive is terminated for reasons other than cause, retirement, death or
      disability, or voluntarily leaves employment for reasons specified in the
      SERP, the executive may elect either to take early retirement, if
      otherwise qualified to do so, or to receive a lump sum cash payment equal
      to the actuarially determined present value of normal retirement benefits
      based on ten years of service.  Some or all of the amounts to be paid will
      be funded out of the cash value of a life insurance policy paid for by
      SDG&E on behalf of the executive.      
    
         The lump sum payment under the SERP is limited.  If that payment alone,
      or when added together with other payments that the executive has the
      right to receive from SDG&E in connection with a change in control of
      SDG&E, becomes subject to the excise tax imposed by Section 4999 of the
      Code, the payment must be reduced until no such payment is subject to the
      excise tax.  The effect of this limitation is that total severance
      payments made to an executive in connection with a change in control of
      SDG&E may not exceed approximately 2.99 times the executive's average W-2
      income for the five years preceding the change of control.      
    
         Certain significant events described in the SERP constitute a change in
      control, such as the dissolution of SDG&E, the sale of substantially all
      the assets of SDG&E, a merger or the acquisition by one person or group of
      the beneficial ownership of more than 25% of the voting power of SDG&E
      coupled with the election of a new majority of the Board.  An SDG&E-
      initiated merger in which SDG&E is the surviving entity is not a change in
      control; accordingly, the proposal regarding the formation of a holding
      company structure for SDG&E and related restructuring set forth below
      under "Item No. 2 - Formation of a Holding Company Structure" will not
      constitute a change in control.  The adverse actions that allow an
      executive to leave employment voluntarily are described in the SERP and
      consist of events such as a significant and adverse change in the
      executive's position, duties, responsibilities or status, or the reduction
      or elimination of the executive's compensation or incentive compensation
      opportunities.

      Executive Severance Allowance Plan      
    
         SDG&E's Executive Severance Allowance Plan, as amended (the "Executive
      Severance Plan"), covers officers with one or more years of employee
      service in lieu of coverage under the SDG&E severance plan for non-officer
      employees.      
    
         The Executive Severance Plan provides two different severance
      allowances depending upon whether the officer's termination is related to
      a change in control of SDG&E.  Termination unrelated to a change in
      control essentially means a termination due to a reduction in staff, or a
      termination resulting from SDG&E's sale of a work unit.  The term change
      in control includes such significant events as those described under
      "Pension Plan and Supplemental Executive Retirement Plan" above.  If,
      within three years after a change in control, the officer is terminated
      for reasons other than cause, retirement, death or disability, or leaves
      employment voluntarily due to adverse actions, the officer is entitled to
      a severance allowance.  The adverse actions that allow an officer to leave
      employment voluntarily are described in the Executive Severance Plan and
      consist of events such as a significant and adverse change in the
      officer's position, duties, responsibilities or status, or the reduction
      or elimination by SDG&E (or its successors) of the officer's compensation
      or incentive compensation opportunities.      
    
         In the event of a termination unrelated to a change in control,
      officers with one or more years of employee service, but less than five
      years of employee service, will receive a severance allowance consisting
      of a continuation of base salary and health and basic life insurance
      benefits for nine months.  Officers with five or more years of employee
      service receive a continuation of base salary and such benefits for 12
      months.      
    
         The Executive Severance Plan provides that if the length of an
      officer's severance allowance is greater under the employees' severance
      plan than under the Executive Severance Plan, the officer's severance
      allowance under the Executive Severance Plan will be for that longer
      period.      
    
         In the event of a termination related to a change in control, the
      officer will receive a severance allowance consisting of one year's final
      pay in a lump sum payable within five days after termination and, at the
      officer's option, either the continuation of health and basic life
      insurance coverage for 12 months or a lump sum payment equal to the
      present value of that coverage.  Payments pursuant to the Executive
      Severance Plan alone, or when combined with compensation from other SDG&E
      sources made in connection with a change in control of SDG&E, may not
      exceed approximately 2.99 times the officer's average W-2 income for the
      five years preceding the change in control.      
    
         The Executive Severance Plan provides a procedure and a formula to
      reduce the total payments to be received by an officer by reason of a
      change in control if such total payments would exceed the 2.99 limitation
      (causing an excise tax to be due) and if the officer waives receipt of all
      or a portion of the excess.  Under the formula, an officer's lump sum
      benefit under the SERP would be first reduced, if necessary, to zero.  It
      is not anticipated that any reduction under any other benefit plan would
      be necessary in the case of any officer.

      Report of the Executive Compensation Committee      
    
         The Executive Compensation Committee, which is composed entirely of
      independent outside Directors, acts on behalf of the Board of Directors in
      the interests of the Shareholders in formulating policy and administering
      approved programs for compensating SDG&E's officers and other senior
      executives.      
    
         The compensation policy of SDG&E, with respect to its executives, is to
      provide a total compensation package wherein the mix and total of base
      salary, annual incentive and long-term incentive, the composition of its
      benefit programs, and the terms and administration of the plans by which
      such forms of compensation are determined (1) are structured and
      administered in the best interests of the Shareholders, (2) are reasonable
      in comparison to competitive practice, (3) align the amount of
      compensation with corporate performance, and (4) will continue to motivate
      and reward on the basis of company and individual performance.  The
      Executive Compensation Committee believes that a significant portion of
      the total compensation of all executives, and most specifically, the Chief
      Executive Officer, should be "at risk" and based upon the achievement of
      measurable, superior financial and operational performance.      
    
         In discharging its responsibility, the Executive Compensation
      Committee, subject to the final approval of the Board of Directors,
      determines the factors and criteria to be used in compensating the Chief
      Executive Officer, as well as other executives of SDG&E, and applies these
      factors and criteria in administering the various plans and programs in
      which these executives participate to ensure they are (1) consistent with
      SDG&E's compensation policy, (2) compatible with SDG&E's other
      compensation programs and (3) administered in accordance with their terms
      and the objectives for which they are intended.      
    
         To assist in the performance of the above and to ensure that it is
      provided with unbiased, objective input, the Executive Compensation
      Committee has retained the services of an outside independent compensation
      consulting firm.  This firm provides advice to the Executive Compensation
      Committee with respect to the reasonableness of compensation paid to
      executives of SDG&E.  In doing so, it takes into account and advises the
      Executive Compensation Committee of the compensation practices of, and
      compensation levels paid by, comparable utility companies of similar size
      and geographic location.  These companies, with the exception of certain
      gas utilities, are included in the Dow Jones Utilities Index referenced in
      the performance graph below (see "Comparative Common Stock Performance").
      The Executive Compensation Committee considers the compensation practices
      and levels paid by major non-utility companies located in California.
      Increased competition also requires the collection of comparative
      information from deregulated companies nationwide.  In addition, the
      Executive Compensation Committee reviews economic and comparative
      compensation surveys compiled and provided by the Human Resources
      department of SDG&E.  The Executive Compensation Committee believes that
      by taking into account the compensation practices of other comparative
      utilities as well as major California non-utility companies, it can best
      determine the level of compensation necessary to attract, retain and
      motivate its executives.      

                                       19
<PAGE>
 
    
         While it may rely on such information, the Executive Compensation
      Committee is ultimately and solely responsible for any decisions made or
      recommended to the Board of Directors with regard to the compensation of
      SDG&E's executives.      
    
         The Executive Compensation Committee has reviewed the compensation of
      SDG&E's executives and has determined that their compensation is
      consistent with SDG&E's policy.      
    
         Chairman, President and Chief Executive Officer Compensation      
         ------------------------------------------------------------
    
         The compensation of the Chairman, President and Chief Executive
      Officer, Mr. Thomas A. Page, as well as that of the other executives, is
      directly tied to the achievement of the corporate goals described below.
      The base salary of the Chief Executive Officer, and the other executives,
      is targeted at the competitive median (50th percentile) for comparably
      sized utilities and companies.  Pursuant to Mr. Page's employment
      agreement described above, he will receive a salary of not less than
      $31,916.66 per month.  The Chief Executive Officer's targeted
      participation levels are 50% under the EICP and 61% under the LTIP, of
      base salary.  Actual incentive compensation earned under these two plans
      is contingent upon SDG&E's attaining stated performance goals.  At
      targeted compensation levels, 53% of the Chief Executive Officer's total
      compensation is contingent on the achievement of these quantifiable
      corporate performance goals.  As discussed further below in the EICP and
      LTIP sections, these goals include earnings per share, return on equity,
      market-to-book, operating and maintenance expenses, rates, electric
      reliability, safety, and customer satisfaction.      
    
         Base Salary Compensation      
         ------------------------
    
         The base salary component for the Chief Executive Officer and the other
      executives is reviewed annually and is based upon the responsibilities of
      the position and the experience of the individual.  The Executive
      Compensation Committee also takes into account the base salaries of
      executives with similar responsibilities at the above-mentioned companies.
      Other factors taken into consideration by the Executive Compensation
      Committee are the condition of the local and national economies and
      SDG&E's financial and operational health.  The individual performance of
      the specific executive is also considered.  The base salary information is
      gathered and analyzed in order to determine the appropriate compensation
      level.  While these statistical factors may warrant one level of pay, more
      subjective elements such as the condition of the economy may dictate
      another.      
    
         Executive Incentive Compensation Plan (EICP)      
         --------------------------------------------
    
         Under the EICP, cash payments may be made annually to the Chief
      Executive Officer and other executives based on a combination of financial
      and operating performance goals.  There are three elements that determine
      the individual awards: (1) the executive's base salary; (2) the
      participation level; and (3) corporate performance.  The participation
      level is expressed as a percentage and is set by the Executive
      Compensation Committee based on the executive's duties and level of
      responsibility.  The amount of the individual award is determined by
      multiplying the executive's base salary by the participation level and
      then modifying it by total corporate performance.      

                                       20
<PAGE>
 
    
         The EICP is highly leveraged on the basis of performance.  Accordingly,
      no payments may be made unless and until the minimum performance levels
      are exceeded.  Under the terms of the EICP, corporate performance is
      measured against preset quantifiable goals approved by the Executive
      Compensation Committee at the beginning of the year.  A target and a
      minimum and maximum performance range are established for each goal.
      Financial goals include (1) the percent return on shareholders' equity and
      (2) the ratio of SDG&E's stock market price to its book value, which is
      then compared to other utilities. Operating goals include (1) adherence to
      SDG&E's operating budget, (2) an electric rate target, (3) customer
      service satisfaction as measured by customer surveys, (4) average customer
      electric outage, and (5) lost-time accidents. Total corporate performance
      is determined from the degree of achievement of each of these goals. These
      goals directly support the performance-based rates goals approved by the
      California Public Utilities Commission. The Executive Compensation
      Committee gives equal weight to the financial goals and the operating
      goals in order to balance Shareholder and customer interests. This serves
      to assist SDG&E in reaching its goals of lowering rates and increasing
      earnings at the same time.      
    
         All 1994 operating performance minimum goals were met or exceeded with
      customer satisfaction achieving an all-time high and safety experiencing
      an all-time low number of accidents.  Due to non-recurring write-downs,
      the 1994 financial goal of return of shareholders' equity was not met,
      although SDG&E's market-to-book ratio is still in the top 25% of
      utilities.  For 1994, the individual awards could not exceed 75% of base
      salary for the Chief Executive Officer and 60% for other executives.  The
      EICP compensation component represents 24% of the Chief Executive
      Officer's total mix of compensation based upon the targets set under the
      EICP and LTIP.  The actual amounts earned by each of SDG&E's five highest
      compensated executives under the EICP are listed in the Summary
      Compensation Table.      
    
         1986 Long-Term Incentive Plan (LTIP)      
         ------------------------------------
    
         The LTIP was approved by the Shareholders in 1986 to promote the
      interests of SDG&E and its Shareholders.  The LTIP was presented to the
      Shareholders for vote and included the term and number of shares approved
      for issue.  The LTIP delegates the responsibility of administration and
      goal determination to the Executive Compensation Committee.  The LTIP's
      primary purpose is to enhance the value of SDG&E to its Shareholders by
      encouraging executives to remain with SDG&E and to act and perform to
      increase the price of SDG&E's shares and its earnings per share.  To
      accomplish these objectives, SDG&E sells shares of its stock to its
      executives at a fixed price of $2.50 per share.  These shares are subject
      to substantial restrictions on the rights of SDG&E's executives to benefit
      fully from such shares unless and until certain company earnings
      improvement and continued service requirements are met.  If these
      requirements or other criteria are not met, it is anticipated that the
      executives' rights to such shares would be forfeited and they would be
      sold back to SDG&E at their original purchase price.      
    
         All of SDG&E's executives are eligible to participate in the LTIP at
      various levels.  The number of shares granted is determined by a formula
      adopted by the Executive Compensation Committee, and is calculated as a
      percentage of base salary.  The higher the salary level, the higher the
      participation level (or percentage of risk).  For example, in 1994 the 
     

                                       21
<PAGE>
 
    
      Officer participated at 61% of base salary, making the LTIP equal to 29%
      of his mix of total target compensation. As a component of the executives'
      total compensation package, the LTIP formula is reviewed annually. The
      review takes into consideration that the value of such shares, at the time
      of grant, has been determined to be consistent with the size of grants
      made to executives in similar positions in the above-mentioned companies.
      Other factors accounted for are LTIP goals, current share ownership and
      current participation levels.      
    
         With respect to LTIP shares purchased in 1990, 1991, 1992, 1993 and
      1994, restrictions on one-quarter of the number of shares originally
      placed in escrow are to be released and the shares are to be delivered to
      the executives for each of the four succeeding calendar years if SDG&E's
      earnings per share meet or exceed the earnings per share target set by the
      Executive Compensation Committee or if, at the end of the first, second
      and third quarters of the following year, earnings for the twelve months
      then ending equal or exceed the weighted average of the targets for the
      prior year and the current year.  In addition, as to shares purchased in
      1990, 1991 and 1992, the restrictions on all remaining shares that are not
      released in such manner will be released and the shares will be delivered
      to executives at the end of the fourth succeeding calendar year, if and
      only if, a total return to Shareholders goal, as determined by the
      Executive Compensation Committee or the Board, is met.  Shares purchased
      in 1993 have no end of term goal.  As to shares purchased in 1994, the
      restrictions on all remaining shares may be released by the Board of
      Directors after considering the impact on 1995 - 1998 earnings of industry
      and corporate restructuring during such period.      
    
         In addition to the above-described restricted shares with four-year
      performance period-based restrictions, a special grant of 2,500 shares was
      made to each of S. L. Baum and D. E. Felsinger in 1994.  The restrictions
      on these shares are to be lifted at the end of 1996 if the Company meets
      or exceeds the target earnings per share for 1996 as set by the Executive
      Compensation Committee.  Such target earnings may be adjusted to reflect
      industry and corporate restructuring.      
    
         With respect to LTIP shares purchased in 1990, the total return to
      Shareholders goal as set by the Board of Directors for the four-year
      period ending in 1994 was met, the restrictions have been lifted and all
      shares have been delivered to the executives.  However, since the one-year
      earnings per share goal was not met at year-end 1994, the shares issued in
      1991, 1992 and 1993 which could have been released in 1994 are still held
      in escrow.      
    
         The number of restricted shares sold to SDG&E's five highest-
      compensated executives in 1994, pursuant to the LTIP, is shown in the
      Long-Term Incentive Plan Table.  The goals for restricted shares sold in
      1994 are based on the achievement of increased earnings per share.      
    
         Revenue Reconciliation Act of 1993      
         ----------------------------------
    
         In 1993 Section 162(m) of the Internal Revenue Code was amended to
      limit the deductibility of most forms of compensation, over $1,000,000,
      paid to top executives of publicly-held corporations.  The Executive
      Compensation Committee believes that awards of stock options and stock
      appreciation rights, if any, under the LTIP will not be subject to the
      limitations on compensation deductibility as a result of the amendments
      submitted to the      

                                       22
<PAGE>
 
    
      Shareholders for approval at the Annual Meeting (see "Item No. 3 -
      Amendment of 1986 LTIP" below). The Executive Compensation Committee
      intends to maintain flexibility in the manner and conditions under which
      grants of restricted stock are made under the LTIP, however, and such
      grants may in the future be subject to the limitations on compensation
      deductibility under certain circumstances.      
    
      The report is submitted by the Executive Compensation Committee:

             ITEM NO. 2 - FORMATION OF A HOLDING COMPANY STRUCTURE
             -----------------------------------------------------
      (Item 2 on Common Stock and Cumulative Preferred Stock Proxy Cards)
             (Item 1 on Preference Stock (Cumulative) Proxy Cards)      
    
      General      
    
         The Board of Directors has authorized, subject to Shareholder approval,
      a plan to change the corporate structure of SDG&E and its subsidiaries.
      The result of the restructuring will be to have SDG&E and all of its
      direct subsidiaries become separate subsidiaries of a parent holding
      company, SDO Parent Co., Inc. ("ParentCo"), with the present holders of
      SDG&E Common Stock becoming holders of the common stock of ParentCo,
      without par value ("ParentCo Common Stock"). The direct subsidiaries of
      SDG&E that, in addition to SDG&E, would become direct subsidiaries of
      ParentCo are Pacific Diversified Capital Company, Enova Corporation,
      Califia Company and Enova Energy Management, Inc.     

         Management and the Board of Directors consider the proposed change in
      corporate structure to be in the best interests of SDG&E and its
      Shareholders, believing that a parent holding company, with SDG&E as its
      principal subsidiary, will result in benefits for SDG&E, its Shareholders
      and other constituents.
    
      THE BOARD OF DIRECTORS OF SDG&E RECOMMENDS APPROVAL OF THE PROPOSED
      FORMATION OF A HOLDING COMPANY STRUCTURE AND URGES EACH SHAREHOLDER TO
      VOTE "FOR" THE PROPOSED RESTRUCTURING.     

      Plan of Implementation

         To carry out the restructuring, SDG&E has formed a new California
      corporation, SDO Parent Co., Inc. (which name is subject to change at the
      discretion of the Board of Directors and without further action by the
      Shareholders prior to consummation of the restructuring). ParentCo has, in
      turn, formed a new California corporation, San Diego Merger Company
      ("MergeCo"). Prior to the Merger, (i) MergeCo will have a nominal amount
      of stock outstanding, all of which will be held by ParentCo, and no
      business or properties of its own, and (ii) ParentCo will have no business
      or properties of its own, and its outstanding stock will be held by SDG&E.

         SDG&E, ParentCo and MergeCo have approved an agreement of merger (the
      "Merger Agreement"). The Merger Agreement is subject to certain
      conditions, including shareholder approval as required by California law.
      If the transactions contemplated by the Merger Agreement occur, SDG&E will
      become a subsidiary of ParentCo through the merger of MergeCo into SDG&E
      (the "Merger"). A copy of the Merger Agreement is attached to this Proxy
      Statement as Exhibit A, and is incorporated herein by reference.
    
         In the Merger, each share of SDG&E Common Stock will be converted into
      one share of ParentCo Common Stock. Following the Merger, SDG&E
      will transfer to ParentCo the capital stock of SDG&E's present direct
      subsidiaries so that these companies also will      

                                       24
<PAGE>
 
      become direct subsidiaries of ParentCo (the transfer, the Merger and
      related activity are sometimes referred to in this Proxy Statement and
      Prospectus as the "restructuring").
    
         It is anticipated that the restructuring will not affect the position
      of present Shareholders of SDG&E for federal income tax purposes. See
      "Federal Income Tax Consequences of the Merger" below.     
    
         Except for SDG&E Common Stock, none of the securities of SDG&E,
      including SDG&E Cumulative Preferred Stock, SDG&E Preference Stock
      (Cumulative) and SDG&E's debt securities, will be changed by the Merger.
      The outstanding shares of SDG&E Cumulative Preferred Stock and SDG&E
      Preference Stock (Cumulative) will continue to be outstanding shares of
      SDG&E. See "Treatment of Preferred Stock" below.     
    
      Reasons for the Restructuring      
    
         The principal reason for the proposed restructuring, including the
      formation of ParentCo, is to respond to the changing business environment
      in the electric and gas utility industries in a manner which management
      believes is in the best interests of the Shareholders and customers. The
      proposed restructuring will allow SDG&E to operate its regulated utility
      business efficiently while providing, through the structure of a holding
      company with other direct subsidiaries, an organization which permits
      separation of the other facets of the Company from such regulated utility
      business.     
    
         For over a century, SDG&E has operated predominantly as a traditional
      utility, responsible for constructing and operating the generation,
      transmission and distribution facilities needed to serve its customers.
      However, both regulation of utilities and the markets which SDG&E has
      traditionally served are changing. As facets of the traditional utility
      business which were once regulated, such as electric generation, have
      become less regulated and more competitive, the energy options for
      customers, particularly large industrial users of energy, are expanding.
          
    
         Management believes that the corporate separation afforded by a holding
      company structure will permit the holding company, ParentCo, to respond
      effectively to increasing competition in the energy business. Where a
      facet of the business, such as electric generation, becomes unregulated,
      that business can be separated from the core utility business of SDG&E,
      although remaining under the common ownership of ParentCo. Separation will
      facilitate the development of such unregulated businesses while insulating
      SDG&E from the risks associated with their activities. Following the
      restructuring, any liabilities of the direct subsidiaries of ParentCo
      other than SDG&E will not constitute liabilities of SDG&E. Accordingly,
      any benefits or detriments of these subsidiaries will flow to the security
      holders of ParentCo and not to the security holders of SDG&E (i.e.,
      holders of SDG&E Cumulative Preferred Stock, SDG&E Preference Stock
      (Cumulative) and SDG&E's debt securities).     

         In 1994, the California Public Utilities Commission (the "CPUC") issued
      a proposal to restructure the California utility industry to allow for
      increased competition in certain facets of the utility business. In
      response to such proposal, SDG&E suggested consideration of the

                                       25
<PAGE>
 
      separation of its electric generation assets. SDG&E is currently
      evaluating such a separation and making preparations should the CPUC order
      it. Absent CPUC direction, a separation may nevertheless become expedient
      in view of evolving regulatory and market circumstances. Other facets of
      SDG&E's present business also may become future candidates for separation.
      Any separation of SDG&E assets and resources will be effected in
      compliance with applicable regulatory and security holder approval
      requirements, and the terms of any such separation will depend upon future
      conditions and the scope of involved assets and resources.

         Separation of the competitive, unregulated facets of the energy
      business, as well as the diversified operations of SDG&E's present
      subsidiaries (Pacific Diversified Capital Company, Enova Corporation,
      Califia Company and Enova Energy Management, Inc.), from the core utility
      business of SDG&E will help to protect SDG&E's stability as viewed by
      sources of financing. Such stability is vital to avoid increased capital
      costs for SDG&E which would lead to higher utility rates. Accordingly, the
      holding company structure will support SDG&E's ability to continue
      efficiently meeting its customers needs while permitting the Company to
      respond to a changing business environment.

         Management also believes that the holding company structure will permit
      the use of financing techniques that are more directly suited to the
      particular requirements, characteristics and risks of non-utility
      operations without any impact on the capital structure or credit of SDG&E.
      Management anticipates that (i) ParentCo, in addition to receiving
      dividends from SDG&E (and other direct subsidiaries of ParentCo), may
      obtain funds through debt or equity financings, (ii) SDG&E may obtain
      funds through its own financings (which may include the issuance of first
      mortgage bonds or preferred stock, as well as the issuance of additional
      shares of SDG&E Common Stock to ParentCo), and (iii) the non-utility
      businesses may obtain funds from ParentCo, from other non-utility
      affiliates or from their own outside financings. Any financings will
      depend upon the financial and other conditions of the entities involved
      and on market conditions.
    
         The proposed restructuring provides for a holding company that will not
      be a utility. Neither ParentCo nor any securities it issues will be
      subject to the jurisdiction of the CPUC, the Federal Energy Regulatory
      Commission (the "FERC") or the Nuclear Regulatory Commission (the "NRC");
      provided, however, that (i) as the sole owner of SDG&E Common Stock,
      ParentCo may be indirectly subject to such jurisdiction with respect to
      certain matters due to the application to SDG&E of laws, orders and rules
      which can affect and regulate utilities, and (ii) rules or orders of these
      commissions may impose restrictions on ParentCo's relationship with SDG&E
      that are designed to protect utility customers, to promote the common
      defense and security, or to protect the health and safety of the public.
      See "Regulation" below. The utility business of SDG&E will constitute the
      predominant part of ParentCo's earning power for the foreseeable future
      after the restructuring.     

         Following the restructuring, SDG&E will continue to operate as a public
      utility subject to the jurisdiction of the CPUC, the FERC and the NRC. The
      operations of SDG&E will continue to be conducted as they are at the
      present time, with the same assets and management.

                                       26

      Management and the SDG&E Board of Directors believe that the restructuring
      will have no adverse effect on SDG&E, its continuing security holders or
      its customers.

      Merger Agreement

         The Merger Agreement has been approved by the Boards of Directors of
      SDG&E, ParentCo and MergeCo. Pursuant to the Merger Agreement, the
      following events will occur upon the effectiveness of the Merger:

         . Each outstanding share of SDG&E Common Stock will be automatically
           converted into one share of ParentCo Common Stock.

         . Each outstanding share of SDG&E Cumulative Preferred Stock and SDG&E
           Preference Stock (Cumulative) will continue as one such issued and
           outstanding share, with the same voting powers, designations,
           preferences, rights, qualifications, limitations and restrictions,
           just as prior to the Merger.

         . The outstanding shares of the common stock of MergeCo will be
           automatically converted into all of the issued and outstanding shares
           of SDG&E Common Stock, all of which will then be owned by ParentCo
           (with the effect that the number of issued and outstanding shares of
           SDG&E Common Stock immediately after the Merger will be the same as
           the number of issued and outstanding shares of SDG&E Common Stock
           immediately prior to the Merger).

         . The shares of ParentCo Common Stock presently held by SDG&E will be
           canceled.

      As a result, SDG&E, which will be the surviving corporation in the Merger,
      will become a subsidiary of ParentCo, and all of the ParentCo Common Stock
      outstanding immediately after the Merger will be owned by the holders of
      SDG&E Common Stock outstanding immediately prior to the Merger.
    
         Following the Merger, SDG&E will complete the restructuring by
      transferring the capital stock of SDG&E's present direct subsidiaries
      (Pacific Diversified Capital Company, Enova Corporation, Califia Company
      and Enova Energy Management, Inc.) to ParentCo.     

      Amendment or Termination

         By mutual consent of their respective boards of directors, SDG&E,
      ParentCo and MergeCo may abandon the Merger or amend, modify or supplement
      the terms of the Merger Agreement in such manner as may be agreed upon by
      them in writing at any time before or after approval of the restructuring
      by the Shareholders. However, no such amendment, modification or
      supplement shall, if agreed to after such approval by the Shareholders,
      change any of the principal terms of the Merger Agreement. SDG&E will
      notify the Shareholders in the event of any material amendment,
      modification or supplement.

                                       27
<PAGE>
 
    
         The Merger Agreement provides that it may be terminated, and the Merger
      abandoned, at any time, whether before or after approval of the
      restructuring by the Shareholders, by action of the SDG&E Board of
      Directors if such Board determines that the completion of the
      restructuring would for any reason be inadvisable or not in the best
      interests of SDG&E or its Shareholders. In making such determination, the
      SDG&E Board of Directors would consider, among other things, demands for
      cash payments, if any, made by holders of SDG&E Common Stock or SDG&E
      Cumulative Preferred Stock seeking to exercise statutory dissenters'
      rights under applicable California law (described below under "Rights of
      Dissenting Shareholders").     

         The SDG&E Board of Directors would be expected to terminate and abandon
      the restructuring, for example, if SDG&E has not received, within a
      reasonable period after Shareholder approval, the approval of the CPUC on
      terms which are satisfactory to the SDG&E Board of Directors. SDG&E is
      unable to predict under what other circumstances the restructuring might
      be terminated and abandoned.

      Treatment of Preferred Stock

         The proposed Merger and restructuring will not result in any change in
      SDG&E's two outstanding classes of preferred stock (SDG&E Cumulative
      Preferred Stock and SDG&E Preference Stock (Cumulative)). The decision of
      the SDG&E Board of Directors to have SDG&E Cumulative Preferred Stock and
      SDG&E Preference Stock (Cumulative) continue as securities of SDG&E is
      based upon, among other things, a desire to avoid changing the nature of
      the investment represented by such stock, as well as the desire of SDG&E
      not to foreclose future issuances of preferred stock to help meet its
      capital requirements. SDG&E's debt securities also will not be altered in
      the Merger; rather, these securities will remain outstanding and will
      continue as obligations of SDG&E as the survivor of the Merger (in the
      case of SDG&E's first mortgage bonds, continuing to be secured by a first
      mortgage lien on the properties of SDG&E that are subject to such lien).

         The utility operations of SDG&E presently constitute, and are expected
      to continue to constitute for the foreseeable future, the substantial
      majority of the affiliated group's consolidated assets and earning power.
      Accordingly, it is believed that SDG&E Cumulative Preferred Stock and
      SDG&E Preference Stock (Cumulative) will retain their investment rating,
      as well as their qualification for legal investment, by remaining
      outstanding securities of SDG&E.

         SDG&E Cumulative Preferred Stock and SDG&E Preference Stock
      (Cumulative) will continue to rank senior to SDG&E Common Stock (all of
      which, after the Merger, will be held by ParentCo) as to dividends and as
      to the distribution of assets of SDG&E in the event of any liquidation of
      SDG&E.  SDG&E Cumulative Preferred Stock and SDG&E Preference Stock
      (Cumulative) are and will be unrelated in rank to ParentCo Common Stock or
      the common stock of other direct subsidiaries to be held by ParentCo
      (initially, Pacific Diversified Capital Company, Enova Corporation,
      Califia Company and Enova Energy Management, Inc.).  Payment of dividends
      on ParentCo Common Stock will in large part depend on the earnings of
      SDG&E and payment of dividends on SDG&E Common Stock.  SDG&E's Restated
      Articles 

                                       28
<PAGE>
 
      will continue to provide that no dividends may be paid on SDG&E Common
      Stock unless dividends are current on SDG&E Cumulative Preferred Stock and
      SDG&E Preference Stock (Cumulative). Payment of any dividends on the
      common stock of any other direct subsidiaries held by ParentCo will be
      unaffected by any dividend payment or nonpayment on either SDG&E
      Cumulative Preferred Stock, SDG&E Preference Stock (Cumulative) or SDG&E
      Common Stock.

         Separation from SDG&E of the assets and earnings of its non-utility
      subsidiaries will decrease the assets and may decrease the earnings of
      SDG&E, and will result in SDG&E's investment in these subsidiaries being
      no longer of potential benefit to holders of SDG&E Cumulative Preferred
      Stock, SDG&E Preference Stock (Cumulative) or SDG&E's debt securities
      (i.e., any earnings of these subsidiaries will not be available to pay
       ----                                                                 
      dividends, interest or principal with respect to such securities).
      However, the SDG&E Board of Directors believes that such holders will not
      be materially affected by the separation.  SDG&E's net investment in its
      non-utility subsidiaries was approximately $106 million at September 30,
      1994, representing approximately 7.2% of the SDG&E Common Stock
      shareholders' equity as of that date.  If the separation of the non-
      utility subsidiaries had occurred on January 1, 1994, the net income
      (before SDG&E Cumulative Preferred Stock and SDG&E Preference Stock
      (Cumulative) dividend requirements) of SDG&E for the nine months ended
      September 30, 1994 would have increased by approximately $62.3 million, or
      approximately 72.2%, and total assets would have decreased by
      approximately $454.1 million, or approximately 9.9%.  However, such
      increase in net income reflected for SDG&E for the nine months ended
      September 30, 1994 had such separation occurred on January 1, 1994 is
      affected by a significant charge during such period for writedowns at the
      non-utility subsidiaries of approximately $67 million (related to non-
      earning assets - see "Pro Forma Financial Effects" below).  In the absence
      of such writedowns, such net income would have decreased upon a separation
      by approximately $4.7 million, or approximately 3.1%.

         The SDG&E Board of Directors believes that the separation will have no
      material adverse effect on SDG&E's utility operations or on its financial
      position or results of operations.  Following the Merger, SDG&E will
      continue to be a reporting company under the Securities Exchange Act of
      1934, as amended.  While annual meetings of SDG&E shareholders are
      expected to continue to be held after the Merger, SDG&E may decide not to
      solicit proxies from holders of SDG&E Cumulative Preferred Stock or SDG&E
      Preference Stock (Cumulative) in connection with the election of directors
      and in connection with other matters requiring the approval of
      shareholders but not requiring a class vote of holders of SDG&E Cumulative
      Preferred Stock or SDG&E Preference Stock (Cumulative), since the shares
      of SDG&E Common Stock owned by ParentCo will have sufficient voting power
      to take action without the vote of SDG&E Cumulative Preferred Stock or
      SDG&E Preference Stock (Cumulative).

      Pro Forma Financial Effects

         The following table summarizes certain pro forma financial effects of
      the restructuring as of September 30, 1994, for the nine months ended
      September 30, 1994, and for the year ended December 31, 1993, which, in
      the opinion of management, reflect all adjustments necessary for a fair
      presentation.

      (1) Pro forma SDG&E amounts have been adjusted to eliminate subsidiaries
          to be transferred to ParentCo.

      (2) Pro forma amounts assume no exercise of preferred stockholders'
          dissenters' rights.  Preferred stock of SDG&E and related dividends
          have been reclassified.
    
      (3) Includes charges of approximately $80 million for SDG&E (as reported,
          or ParentCo on a consolidated pro forma basis), or $0.68 per common
          share, for June 1994 writedowns

          related to non-earning assets of SDG&E (on a pro forma basis --
          approximately $13 million) and non-SDG&E subsidiaries of ParentCo
          (approximately $67 million).

      Dividend Policy
        
          It is anticipated that quarterly dividends on ParentCo Common Stock
      will commence at a rate equal to that currently being paid on SDG&E Common
      Stock, and will be paid on approximately the same dates in each year as
      dividends on SDG&E Common Stock have been paid.  [The quarterly dividend
      most recently declared by the SDG&E Board of Directors was $0.38 per share
      of SDG&E Common Stock payable on January 15, 1995 to holders of record on
      December 10, 1994.]  The rate and timing of dividends of ParentCo will
      depend upon the earnings, financial condition and dividend restrictions of
      ParentCo and its subsidiaries, including SDG&E, and upon other factors
      affecting dividend policy which are not presently determinable.      

          Initially, the funds required by ParentCo to enable it to pay
      dividends on ParentCo Common Stock are expected to be derived primarily
      from dividends paid by SDG&E on SDG&E Common Stock.  It is anticipated
      that such cash dividends paid by SDG&E to ParentCo will be sufficient,
      together with any amounts provided by other subsidiaries of ParentCo, to
      enable ParentCo to pay cash dividends on ParentCo Common Stock and to meet
      operating and other expenses.  However, the dividend policy of SDG&E will
      be established by SDG&E's Board of Directors as though SDG&E were a stand-
      alone utility, and the amounts of dividends declared and paid by SDG&E
      will be subject to the availability of earnings and the needs of the
      utility business, as well as CPUC requirements.  In addition, the ability
      of SDG&E to pay dividends on SDG&E Common Stock to ParentCo will be
      subject to the prior dividend rights of SDG&E Cumulative Preferred Stock
      and SDG&E Preference Stock (Cumulative), to restrictions contained in the
      indenture supporting SDG&E's first mortgage bonds and other agreements to
      which SDG&E is or may become a party, and to requirements of California
      law.

          Payment of dividends on SDG&E Cumulative Preferred Stock and SDG&E
      Preference Stock (Cumulative) is anticipated to continue at the specified
      rates without interruption or change; however, the payment of these
      dividends is also dependent upon the earnings and financial condition of,
      and other factors affecting, SDG&E.

      Directors and Management of ParentCo and SDG&E
    
          The Directors of SDG&E elected at the Annual Meeting will also be the
      Directors of ParentCo after the completion of the restructuring (see "Item
      No. 1 - Election of Directors" above).  In approving the Merger Agreement
      and the proposed formation of a holding company structure for SDG&E,
      Shareholders will be considered also to have ratified the election of
      these persons as Directors of ParentCo (as well as ratifying the
      establishment of a classified Board for ParentCo and the inclusion of
      certain Directors within the various classes as set forth below - see
      "Articles of Incorporation and Bylaws of ParentCo" and "Elections:
      Classified Board of Directors" below).  At annual meetings of ParentCo
      subsequent to the Merger, persons may be nominated for election as
      Directors of ParentCo who will not be members of the SDG&E Board of
      Directors.

          The following persons, each of whom is currently an executive officer

</TABLE> 
     
         Initially, ParentCo will not have full-time officers and employees of
      its own.  To the extent, however, that the activities of ParentCo expand,
      ParentCo may employ full-time salaried officers and employees.  ParentCo
      and SDG&E each expect, from time to time, to render to the other certain
      services and to make available the use of certain facilities and
      equipment.  The corporation receiving such services or using such
      facilities and equipment will reimburse the other corporation for the cost
      or fair market value thereof, as appropriate.

      Articles of Incorporation and Bylaws of ParentCo
    
         The articles of incorporation of ParentCo, as they shall be amended and
      restated prior to the effectiveness of the Merger (the "ParentCo
      Articles"), have been prepared in accordance with the California General
      Corporation Law (the "California GCL") and give ParentCo broad corporate
      powers to engage in any lawful activity for which a corporation may be
      formed under the laws of the State of California.  The name "SDO Parent
      Co., Inc.," which is presently set forth in the ParentCo Articles, is
      subject to change at the discretion of the Board of Directors and without
      further action by the Shareholders prior to consummation of the Merger.
      The following statements summarize certain relevant provisions of the
      ParentCo Articles.  This summary should be read in the context of, and is
      qualified by reference to, (i) the full ParentCo Articles, a copy of which
      is attached to this Proxy Statement and Prospectus as Exhibit B, and (ii)
      the laws of the State of California.  By approving the Merger Agreement
      and the proposed formation of a holding company structure for SDG&E,
      Shareholders will be ratifying the provisions of the ParentCo Articles.
     
         The ParentCo Articles contain certain provisions which are similar to
      the SDG&E Restated Articles; however, aside from the deletion of certain
      provisions which are obsolete or unnecessary or which specifically concern
      SDG&E Cumulative Preferred Stock and SDG&E

                                       33
<PAGE>
 
      Preference Stock (Cumulative), there are certain distinctions which are
      noted below. Shareholders should be aware that one effect of these
      distinct provisions of the ParentCo Articles may be to delay and thus make
      more difficult a change in the composition of the ParentCo Board of
      Directors as compared with the SDG&E Board of Directors, or the removal of
      existing management, even in circumstances where a majority of the
      shareholders of ParentCo may be dissatisfied with the performance of the
      incumbent Directors or otherwise desire to make changes.

         Analysis of distinctions in the ParentCo Articles should be tempered,
      however, by reference to SDG&E's status as a substantially regulated
      entity (see "Regulation" below).  For example, changes in control of SDG&E
      typically would be subject to CPUC review and approval.  Accordingly,
      while certain provisions of the ParentCo Articles may have the effect of
      making changes in Board composition and management subject to delay and
      thus more difficult, the transition from holding stock in a regulated
      utility to holding stock in ParentCo may have the effect of lessening
      other restrictions (e.g., certain regulatory reviews of a change in
                          ----                                           
      control) affecting a shareholder's ability to influence corporate policy
      and control.

         Capital Stock
         -------------

         The ParentCo Articles authorize the issuance of 300 million shares of
      ParentCo Common Stock and 30 million shares of preferred stock of ParentCo
      (the "ParentCo Preferred Stock").  Immediately after the Merger, ParentCo
      will have approximately 116,541,000 shares of ParentCo Common Stock and no
      shares of ParentCo Preferred Stock outstanding.  Under California law,
      shares of ParentCo Common Stock and ParentCo Preferred Stock may be issued
      by ParentCo from time to time upon such terms and for such consideration
      (and, as to Preferred Stock, having such rights, preferences, privileges
      and restrictions) as may be determined by the ParentCo Board of Directors.
      Such further issuances, up to the aggregate amounts authorized by the
      ParentCo Articles, will not require authorization from the CPUC or
      approval by the shareholders.  ParentCo may issue ParentCo Common Stock
      from time to time pursuant to common stock investment and employee benefit
      plans (see "Common Stock Investment and Employee Benefit Plans" below).
      Aside from these plans, there presently are no intentions to offer or sell
      shares of ParentCo Preferred Stock or additional shares of ParentCo Common
      Stock.  Under current provisions of the Public Utility Holding Company Act
      of 1935, as amended (the "Holding Company Act"), and the rules and
      regulations thereunder, issuance of ParentCo Preferred Stock may be
      restricted.

         Holders of ParentCo Common Stock, subject to any prior rights or
      preferences of ParentCo Preferred Stock outstanding, (i) have equal rights
      to receive dividends if and when declared by the ParentCo Board of
      Directors out of funds legally available therefor and (ii) will receive
      any distribution made to shareholders upon liquidation.  ParentCo Common
      Stock has no preemptive rights to subscribe for additional shares of
      ParentCo Common Stock or other securities of ParentCo, nor does it have
      any redemption or conversion rights.  ParentCo Common Stock has voting
      rights on the basis of one vote per share.  Any series of ParentCo
      Preferred Stock issued by ParentCo will have such voting rights as may be
      determined by the ParentCo Board of Directors at the time of issuance;
      however, the present policies of the national stock exchanges 

                                       34
<PAGE>
 
      against issuances of stock with disparate voting rights may serve to limit
      ParentCo's issuances of any ParentCo Preferred Stock with enhanced voting
      rights.

         Number of Directors
         -------------------

         The California GCL allows the number of persons constituting the board
      of directors of a corporation to be fixed by the bylaws or the articles of
      incorporation, or permits the bylaws to provide that the number of
      directors may vary within a specified range, the exact number to be
      determined by the board of directors.  The California GCL further provides
      that, in the case of a variable board, the maximum number of directors may
      not exceed two times the minimum number minus one.  The bylaws of SDG&E
      (the "SDG&E Bylaws") provide for a Board of Directors that may vary
      between seven (7) and thirteen (13) members, inclusive, and the SDG&E
      Board of Directors has presently fixed the exact number of directors at
      ten (10).  The SDG&E Bylaws permit the range of directors, and the precise
      number within such range, to be modified by a majority of the outstanding
      SDG&E shares entitled to vote.

         The ParentCo Articles provide that the number of directors of ParentCo
      shall not be fewer than nine (9) nor more than thirteen (13), with the
      exact number to be determined by the ParentCo Board of Directors or by a
      bylaw or an amendment thereof adopted by a vote of the holders of shares
      representing at least 66-2/3% of the outstanding shares of ParentCo
      entitled to vote.  The ParentCo Board is presently fixed at ten (10), and
      its membership is identical to the SDG&E Board of Directors.  The ParentCo
      Articles also provide that the range of directors, and the precise number
      within such range, may be modified by a vote of the holders of at least
      66-2/3% of the outstanding ParentCo shares.  ParentCo has no current
      intention of changing the number of directors of ParentCo if the Merger is
      consummated.

         Cumulative Voting
         -----------------

         Under cumulative voting, each share of stock entitled to vote in an
      election of directors has such number of votes as is equal to the number
      of directors to be elected.  A shareholder may then cast all of his or her
      votes for a single candidate or may allocate them among as many candidates
      as the shareholder may choose.  As a result, shareholders holding a
      significant minority percentage of the outstanding shares entitled to vote
      in an election of directors may be able to effect the election of one or
      more directors.  If cumulative voting is available, then it is mandatory
      upon timely notice given by any shareholder at a meeting at which
      directors are to be elected.

         The SDG&E Bylaws provide for the elimination of cumulative voting, as
      do the ParentCo Articles.  Thus, the holder or holders of shares
      representing a majority of the votes entitled to be cast in an election of
      directors for ParentCo will be able to elect all directors then being
      elected.  The absence of cumulative voting could have the effect of
      preventing representation of minority shareholders on the ParentCo Board
      of Directors.

         Elections: Classified Board of Directors
         ----------------------------------------
    
         The California GCL generally requires that directors be elected
      annually but does permit a "classified" board of directors if a
      corporation either (i) has outstanding securities listed on the New York
      Stock Exchange (the "NYSE") or the American Stock Exchange (the "AMEX") or
      (ii) has securities designated for trading as a National Market System
      security on the National Association of Security Dealers Automatic
      Quotation ("Nasdaq") and at least 800 shareholders (including record and
      beneficial owners) (collectively, "Listed Corporations"). SDG&E is a
      Listed Corporation and ParentCo will, upon the effectiveness of the Merger
      or promptly thereafter, be a Listed Corporation. SDG&E's Restated Articles
      currently do not provide for a classified board, and the Directors of
      SDG&E, who are also the Directors of ParentCo, are set forth above under
      "Item No. 1 -Election of Directors."      
    
         The ParentCo Articles provide that, upon ParentCo's attainment of
      status as a Listed Corporation (i.e., upon the effectiveness of the Merger
                                      ----                                      
      or promptly thereafter), the ParentCo Board of Directors will become a
      classified board with three classes of directors, with members of one
      class to be elected each year for a maximum term of three years.  By
      approving the Merger Agreement and the proposed formation of a holding
      company structure for SDG&E, Shareholders will be ratifying the election
      of the Directors to the following classes of the ParentCo Board in the
      event the Merger is consummated:      
    
          (1)  Class I (with terms expiring at the next annual meeting of
               ParentCo): Directors R. C. Atkinson, A. Burr and R. A. Collato;
     
    
          (2)  Class II (with terms expiring at the annual meeting of ParentCo
               following the next annual meeting): Directors D. W. Derbes, C. T.
               Fitzgerald and R. H. Goldsmith; and      
    
          (3)  Class III (with terms expiring at the annual meeting of ParentCo
               following the next two annual meetings): Directors W. D. Jones,
               R. R. Ocampo, T. A. Page and T. C. Stickel.      

         With a classified board, unless adequate cause for removal of directors
      exists, at least two annual meetings of shareholders would be required for
      a majority of the shareholders comprising less than a 66-2/3% majority to
      make a change in control of the ParentCo Board of Directors, since only a
      minority of the directors will be elected at each meeting.

         Actions by Written Consent
         --------------------------

         The California GCL permits shareholders, unless specifically prohibited
      by the articles of incorporation, to take action without a meeting by the
      written consent of the holders of at least the number of shares necessary
      to authorize or take such action at a meeting at which all shares entitled
      to vote thereon were present and voted.  SDG&E's Restated Articles do not
      restrict shareholder action by written consent.  Action by written consent
      may, in some circumstances, 

                                       36
<PAGE>
 
      permit the taking of shareholder action opposed by the Board of Directors
      more rapidly than would be possible if a meeting of shareholders were
      required.

         In connection with its evaluation of the restructuring, the Board has
      determined that it is important that it be able to give advance notice of
      and consideration to any action to be voted on by shareholders, and that
      all shareholders be able to discuss at a meeting matters which may affect
      their rights. Accordingly, the ParentCo Articles eliminate actions by
      written consent of shareholders unless either (i) the Board waives the
      prohibition in a particular circumstance or (ii) the action is by the
      unanimous written consent of all shareholders.

         Fair Price Provisions
         ---------------------

         The ParentCo Articles contain "fair price" provisions which are
      substantially similar to those contained in SDG&E's Restated Articles.
      These provisions are intended to reduce the possibility of unfair
      treatment of shareholders in takeover situations.

         Indemnification Provisions
         --------------------------

         The ParentCo Articles contain provisions regarding the indemnification
      of directors, officers and other agents of ParentCo which are
      substantially similar to provisions contained in SDG&E's Restated
      Articles.

         Amendment of Articles
         ---------------------

         Except for the fair price provisions contained in SDG&E's Restated
      Articles (for which amendment requires a 66-2/3% shareholder vote), the
      SDG&E Restated Articles may be amended by the approval of the holders of
      shares having a majority of the votes entitled to be cast for such
      amendment.  The ParentCo Articles provide that the provisions relating to
      (i) indemnification of officers and directors, (ii) the number of
      directors, classification of the board and the election of directors
      (including the limitation on cumulative voting), (iii) the limitation on
      action of shareholders by written consent, (iv) the fair price provisions
      and (v) amendment of the bylaws of ParentCo (the "ParentCo Bylaws") can
      only be amended by a vote of the holders of shares representing at least
      66-2/3% of the outstanding shares of ParentCo entitled to vote.

         Amendment of Bylaws
         -------------------

         The SDG&E Bylaws may be amended or repealed either by the SDG&E Board
      of Directors or by the holders of shares having a majority of the votes
      entitled to be cast for such amendment.  The ParentCo Articles provide
      that (1) upon a vote of at least 66-2/3% of the authorized number of
      directors, the ParentCo Board of Directors will be able to adopt, amend or
      repeal any of the ParentCo Bylaws, and (2) the ParentCo Bylaws may also be
      adopted, amended or repealed by a vote of the holders of shares
      representing at least 66-2/3% of the outstanding shares of ParentCo
      entitled to vote.

         The ParentCo Bylaws initially will be substantially similar to the
      SDG&E Bylaws.

      Listing of ParentCo Common Stock

         ParentCo has applied to list ParentCo Common Stock on the NYSE and on
      the Pacific Stock Exchange (the "PSE").  It is expected that such listings
      will occur on, or soon after, the effective date of the Merger.  At the
      time of the listing of ParentCo Common Stock, SDG&E Common Stock will then
      be delisted from trading on these stock exchanges (all outstanding shares
      will then be held by ParentCo). Shares of SDG&E Cumulative Preferred Stock
      and SDG&E Preference Stock (Cumulative) that are listed on the AMEX and
      the PSE will continue to be so listed.

      Transfer Agent and Registrar

         It is expected that the transfer agent for and the registrar of
      ParentCo Common Stock will be the same as is presently serving in such
      capacities for SDG&E Common Stock: First Interstate Bank of California.

      Common Stock Investment and Employee Benefit Plans

         If the Merger is completed, SDG&E's Common Stock Investment Plan will
      be assumed and continued by ParentCo on and after the effective date of
      the Merger, so that shares of ParentCo Common Stock thereafter will be
      available to the holders of ParentCo Common Stock and the customers of
      SDG&E on the same terms as provided in SDG&E's Common Stock Investment
      Plan.
    
         If the Merger is completed, SDG&E's Savings Plan and 1986 Long-Term
      Incentive Plan will be amended, as and when appropriate, to provide for
      the acquisition of ParentCo Common Stock rather than SDG&E Common Stock.
      Such plans, as well as the Pension Plan and other employee benefit plans
      of SDG&E (collectively, the "Employee Benefit Plans"), also will be
      amended, as and when appropriate, to include eligible employees of
      ParentCo and the subsidiaries of ParentCo other than SDG&E and to make any
      other changes necessary or appropriate as a result of the formation of a
      holding company structure for SDG&E and the related restructuring.      
    
         By approving the Merger Agreement and the proposed formation of a
      holding company structure for SDG&E, the Shareholders will be deemed to
      have approved the actions to be taken in connection therewith and with the
      Employee Benefit Plans, including any amendments to the Employee Benefit
      Plans necessary to accomplish those actions.      

      Regulation

         As a utility, SDG&E is subject to the jurisdiction of the CPUC with
      respect to rates for retail sales, standards of service, issuances of
      securities and certain other matters.  SDG&E is also subject to the
      jurisdiction of (i) the FERC, with respect to certain phases of its
      electric business, including rates for sales at wholesale, rates for
      transmission, interconnections with other electric utilities and
      accounting, and (ii) the NRC, with respect to SDG&E's partial ownership of
      and co-licensee status as to the San Onofre nuclear generating facilities.
      The 

                                       38
<PAGE>
 
    
      formation of a holding company structure for SDG&E, the Merger and the
      related restructuring will not change the applicability of such regulatory
      jurisdiction to SDG&E.  Moreover, SDG&E must obtain certain authorizations
      from the CPUC, the FERC and the NRC to implement various aspects of the
      restructuring.  An application for authorization from the CPUC was filed
      on November 7, 1994, and SDG&E subsequently filed for approvals from the
      FERC and the NRC.      
    
         So long as ParentCo is not a public utility or the owner or licensee of
      nuclear generating facilities, it will not be directly subject to
      regulation by the CPUC, the FERC or the NRC, except to the extent that
      rules or orders of these commissions may impose restrictions on ParentCo's
      relationship with SDG&E that are designed to protect utility customers, to
      promote the common defense and security, or to protect the health and
      safety of the public.  CPUC rules are, for example, designed to (i) ensure
      that all costs incurred by SDG&E which result from the activities
      undertaken by SDG&E's affiliates will be fully recovered from such
      affiliates, (ii) provide the CPUC with access to all information necessary
      to analyze SDG&E's costs and monitor the relationships between SDG&E and
      its non-utility affiliates, (iii) ensure that SDG&E's customers will be
      insulated from effects of non-utility activities, and (iv) protect the
      financial health of SDG&E's utility operations.  SDG&E will continue to be
      subject to CPUC regulation of its operations, including its dealings with
      ParentCo.      
    
         ParentCo believes that it will be entitled to an exemption from all
      provisions of the Holding Company Act except Section 9(a)(2), which
      requires prior approval of the Securities and Exchange Commission (the
      "SEC") for certain utility acquisitions.  The exemption will take effect
      upon completion of the Merger and related restructuring and the filing
      with the SEC of an appropriate exemption statement pursuant to the
      provisions of the Holding Company Act.  It will be necessary to file an
      annual exemption statement each year after that.  The basis of this
      exemption is that both ParentCo and SDG&E, as ParentCo's only public
      utility subsidiary, are incorporated in the same state, are predominantly
      intrastate in character and carry on their business substantially in the
      state of incorporation.  The exemption is available only so long as the
      utility business of SDG&E, and of any other public utility subsidiary from
      which ParentCo derives a material portion of its income, is predominantly
      intrastate in nature.  The exemption may also be revoked on a finding by
      the SEC that such exemption may be detrimental to the public interest or
      the interest of investors or consumers.  The prior approval of the SEC
      under Section 9(a)(2) of the Holding Company Act would be required,
      however, if ParentCo proposed the acquisition, directly or indirectly, of
      additional utility subsidiaries.  ParentCo has no present intention of
      becoming a registered holding company subject to regulation by the SEC
      under the Holding Company Act.

      Conditions Precedent to the Merger

         The Merger Agreement provides that consummation of the Merger is
      subject to approval of the principal terms of the Merger Agreement by the
      shareholders of SDG&E, ParentCo and MergeCo, as more fully set forth below
      under "Required Vote" below.  If the required votes of the Shareholders of
      SDG&E are obtained, SDG&E will then cause the shares of ParentCo and
      MergeCo to be voted in favor of the Merger.
    
         In addition, the Merger is also subject to (i) a review by the CPUC of
      the proposal to form a holding company structure for SDG&E without
      imposition of terms and conditions which are unsatisfactory to the SDG&E
      Board of Directors and (ii) approval by the NYSE of ParentCo Common Stock
      for listing upon official notice of issuance.      

      Effective Date of the Merger
    
         The Merger Agreement provides that the Merger will be effective at the
      end of the last day of the calendar month during which the Merger
      Agreement and related officers' certificates are filed with the California
      Secretary of State as provided in Section 1103 of the California GCL.
      Management anticipates that the effective date will occur prior to or on
      September 30, 1995, although there can be no assurance (e.g., due to
                                                              ----        
      delays which may occur in seeking approval from the CPUC or acceleration
      of that process) that the effective date will not occur prior to or
      subsequent to that date.      

      Required Vote
    
         Under California law and SDG&E's Restated Articles, approval of the
      Merger Agreement and the proposed formation of a holding company structure
      for SDG&E will require the favorable vote of (1) a majority of the
      outstanding shares of SDG&E Common Stock and (2) a majority of the
      outstanding shares of the combined classes of SDG&E Common Stock and SDG&E
      Cumulative Preferred Stock, with each share of SDG&E Common Stock being
      entitled to one vote and each share of SDG&E Cumulative Preferred Stock
      being entitled to two votes.  In addition, the Merger Agreement provides
      that consummation of the Merger is conditioned upon approval by a two-
      thirds majority of the outstanding shares of the combined classes of SDG&E
      Cumulative Preferred Stock and SDG&E Preference Stock (Cumulative), with
      each share being entitled to one vote.      
    
         An abstention, or shares represented by proxies which are marked
      "ABSTAIN," as well as the failure of a broker or other nominee to vote
      shares for a beneficial owner will have the same effect as a vote against
      the Merger Agreement and the proposed formation of a holding company
      structure for SDG&E.

      Rights of Dissenting Shareholders

         The rights of Shareholders who dissent with respect to the Merger are
      governed by Chapter 13, Sections 1300-1312 ("Chapter 13"), of the
      California GCL, the text of which is set forth as Exhibit C to this Proxy
      Statement.  The description of dissenters' rights in this Proxy Statement
      is qualified in its entirety by reference to Chapter 13 of the California
      GCL.

         If the Merger is completed, certain of the Shareholders who object to
      the Merger and who have fully complied with all applicable provisions of
      Chapter 13 of the California GCL will have the right to require SDG&E to
      purchase their shares for cash at the fair market value of such shares as
      of the close of business on November 4, 1994, the business day before the
      terms of the Merger were first announced, excluding any appreciation or
      depreciation because of the proposed Merger.  See "Market Values of Stock"
      below.  Persons who are beneficial owners of shares of SDG&E but whose
      shares are held by another person, such as a broker or nominee, should
      instruct the record holder to follow the procedures outlined below if such
      persons wish to dissent with respect to any or all of their shares.

         The procedural requirements to be complied with differ in some respects
      depending upon whether or not the shares at issue are listed on either (i)
      a national securities exchange certified by the California Commissioner of
      Corporations or (ii) the list of OTC margin stocks issued by the Board of
      Governors of the Federal Reserve System.  The only class of shares
      eligible to be dissenting shares which is not so listed (the "Unlisted
      Shares") is the SDG&E Cumulative Preferred Stock, 4.60% Series.  The
      classes of shares eligible to be dissenting shares which are so listed
      (the "Listed Shares") are (1) all series of SDG&E Cumulative Preferred
      Stock other than the Unlisted Shares and (2) SDG&E Common Stock.  Holders
      of shares of SDG&E Preference Stock (Cumulative) are not entitled to have
      SDG&E purchase their shares.

         Unlisted Shares must be purchased by SDG&E upon compliance by any
      holder with all applicable requirements.  Listed Shares must also be
      purchased by SDG&E if all applicable requirements are complied with, but
      only if (a) demands for payment are filed with respect to five percent
      (5%) or more of the outstanding shares of such class (with shares of SDG&E
      Common Stock treated as one single class for such purposes and all shares
      of SDG&E Cumulative Preferred Stock, other than the Unlisted Shares,
      treated as another single class), or (b) the shares are subject to a
      restriction on transfer imposed by SDG&E or by any law or regulation.  In
      this regard, SDG&E is not aware of any restriction on transfer except
      restrictions that may be imposed upon Shareholders who are deemed to be
      "affiliates" of SDG&E (as that term is defined in Rule 144 adopted by the
      SEC under the Securities Act of 1933, as amended (the "Securities Act"))
      and/or those who received shares in private transactions exempt from the
      registration requirements of the Securities Act.  SDG&E urges any
      Shareholder believing there is any such restriction affecting his or her
      shares to consult with his or her own legal counsel as to the nature and
      extent of any dissenters' rights he or she may have.

         The different procedures for security holders wishing to dissent under
      Chapter 13 of the California GCL with respect to Listed Shares and
      Unlisted Shares are summarized below.

                                       41

         Unlisted Shares
         ---------------

         Assuming SDG&E elects to proceed with the Merger (see "Amendment or
      Termination" above), within ten days after approval of the Merger by the
      Shareholders SDG&E will notify all holders of Unlisted Shares who did not
      vote in favor of the Merger of the approval.  SDG&E will offer all such
      holders a cash price for their shares that SDG&E considers to be the fair
      market value (as described above) of the shares.  The notification will
      also contain a brief description of the procedures to be followed under
      Chapter 13 of the California GCL (and a copy of it) in order for a holder
      of Unlisted Shares to exercise his or her rights to have SDG&E purchase
      such shares.  These procedures include the following requirements:

         (1)    The holder of record must not have voted the shares in favor of
                the Merger.  The holder may, however, have abstained from voting
                without losing the right to have SDG&E purchase his or her
                shares.  The holder may also have voted some of his or her
                shares in favor of the Merger without losing rights as to shares
                not voted in favor of the Merger.

         (2)    Any such holder who wishes to have SDG&E purchase his or her
                shares that were not voted in favor of the Merger must make a
                written demand to have SDG&E purchase the shares for their fair
                market value.  The demand must include the information specified
                below and must be received by SDG&E or its transfer agent within
                30 days after the date on which notice of approval of the Merger
                is mailed by SDG&E to the holder.  See "Demand for Purchase"
                below.

         Listed Shares
         -------------

         For a holder of Listed Shares to exercise the right to have SDG&E
      purchase his or her shares, the procedures to be followed under Chapter 13
      of the California GCL include the following requirements:

         (1)    The holder of record must have voted the shares against the
                Merger.  It is not sufficient to abstain from voting.  However,
                the holder may vote part of his or her shares in favor of the
                Merger or abstain from voting part of his or her shares without
                losing the right to have SDG&E purchase those shares which were
                voted against the Merger.
    
         (2)    Any such holder who voted against the Merger, and who wishes to
                have SDG&E purchase his or her shares that were voted against
                the Merger, must make a written demand to have SDG&E purchase
                the dissenting shares for their fair market value.  The demand
                must include the information specified below and must be
                received by SDG&E or its transfer agent not later than the date
                of the Annual Meeting at which the Merger is approved.  See
                "Demand for Purchase" below.      

                                       42
<PAGE>
 
    
         Assuming SDG&E elects to proceed with the Merger (see "Amendment or
      Termination" above), within ten days after approval of the Merger by
      SDG&E's shareholders, SDG&E will notify any holders of Listed Shares who
      voted against the Merger and made a timely demand for purchase (and who
      are entitled to require SDG&E to purchase their shares because either (1)
      holders of five percent (5%) or more of the outstanding shares of the
      relevant class filed notices by the date of the Annual Meeting or (2) the
      shares are restricted as to transfer) of the approval and will offer all
      of these holders a cash price for their shares which SDG&E considers to be
      the fair market value (as described above) of the shares.  The
      notification will also contain a brief description of the procedures to be
      followed under Chapter 13 of the California GCL (and a copy of it) in
      order for a holder of Listed Shares to exercise his or her right to have
      SDG&E purchase such shares.      

         Demand for Purchase
         -------------------

         Merely voting or delivering a proxy directing a vote against approval
      of the Merger does not constitute a demand for purchase.  A written demand
      is required.  In all cases, the written demand must:

         (1)    Be made by the person who was the holder of record on the Record
                Date (or his or her duly authorized representative) and not by
                someone who is merely a beneficial owner of the shares or a
                holder who acquired the shares subsequent to the Record Date;

         (2)    State the number and class of dissenting shares;

         (3)    Include an offer to sell the shares to SDG&E at what the holder
                believes to be the fair market value of the shares on November
                4, 1994, the business day before the terms of the Merger were
                first announced, excluding any appreciation or depreciation
                because of the proposed Merger.

      In addition, the following conditions apply:

         (a)    The demand should be sent by registered or certified mail,
                return receipt requested.

         (b)    The demand must be signed by the holder of record (or his or her
                duly authorized representative) exactly as his or her name
                appears on the form of proxy accompanying his or her copy of
                this Proxy Statement and Prospectus.

         (c)    A demand regarding shares owned jointly by more than one person
                must identify and be signed by all such holders.

         (d)    Any person signing a demand in any representative capacity (such
                as attorney-in-fact, executor, administrator, trustee or
                guardian) must indicate his or her title and, if SDG&E so
                requests, must furnish written proof of his or her capacity and
                authority to sign the demand.

                                       43
<PAGE>
 
      A demand for payment may not be withdrawn without the consent of SDG&E.

         Other Requirements
         ------------------

         Within 30 days after the date on which notice of approval of the Merger
      is mailed by SDG&E to appropriate Shareholders, a holder's certificates,
      representing any shares which the holder demands that SDG&E purchase, must
      be submitted to SDG&E at its principal offices or to SDG&E's transfer
      agent to be endorsed with a statement that the shares are dissenting
      shares.  Upon subsequent transfer of these endorsed shares, the new
      certificates will be similarly endorsed.

         If SDG&E and a Shareholder fail to agree on either the fair market
      value of the shares or on the eligibility of the shares to be purchased by
      SDG&E, then either the Shareholder or SDG&E may file a complaint for
      judicial resolution of the dispute.  The complaint must be filed within
      six months after the date on which the notice of approval is mailed to
      Shareholders.  If a complaint is not filed within such six-month period,
      the shares will lose their eligibility for status as dissenting shares.
      Two or more dissenting Shareholders may join as plaintiffs or be joined as
      defendants in such an action. If the fair market value of the shares is in
      dispute, the court shall determine, or shall appoint one or more impartial
      appraisers to assist in its determination of, the fair market value. The
      costs of the action will be assessed or apportioned as the court considers
      equitable, but if the fair market value is determined to exceed the price
      offered by SDG&E, then SDG&E will be required to pay such costs. Under
      certain circumstances, SDG&E may also be required to pay attorneys' fees
      and certain other costs.
    
         Any demands, notices or other documents required to be sent to SDG&E
      may be sent to it at Office of the Secretary, 101 Ash Street, P.O. Box
      1831, San Diego, California 92112-4150.  Any demands, notices or other
      documents required to be sent to a transfer agent may be sent to First
      Interstate Bank of California at either (i) Stock Transfer Department,
      P.O. Box 54261, Los Angeles, California 90054 or (ii) 120 Broadway, 13th
      Floor, New York, New York 10271.      

         As mentioned above, under the Merger Agreement the SDG&E Board of
      Directors has the right to abandon the Merger for any reason (even after
      Shareholder approval), and that right may be exercised if the aggregate
      cost of purchasing dissenting shares is not acceptable.  In such case,
      SDG&E will not be obligated to purchase any dissenting shares but may be
      required to pay necessary expenses and reasonable legal fees of
      Shareholders who have in good faith commenced proceedings to enforce their
      dissenters' rights.

      Exchange of Stock Certificates Not Required

           If the proposed restructuring is carried out, it will not be
      necessary for holders of SDG&E Common Stock to exchange their existing
      stock certificates for stock certificates of ParentCo.  Holders of SDG&E
      Common Stock will automatically become holders of ParentCo Common Stock on
      a share-for-share basis, and the present stock certificates for SDG&E
      Common Stock will automatically represent shares of ParentCo Common Stock.

           After the restructuring, as presently outstanding certificates are
      presented for transfer, new certificates bearing the name of SDO Parent
      Co., Inc. (or a name which may be substituted for SDO Parent Co., Inc.
      prior to consummation of the Merger) will be issued.  New certificates of
      ParentCo will also be issued in exchange for old certificates of SDG&E
      upon the request of any Shareholder.  Certificates presented for transfer
      to a name other than that in which the surrendered certificate is
      registered must be properly endorsed, with the signature guaranteed, and
      accompanied by evidence of payment of any applicable stock transfer taxes.

      Federal Income Tax Consequences of the Merger

         SDG&E and ParentCo have been advised by their counsel, Pillsbury
      Madison & Sutro, that:

         (1)    No gain or loss will be recognized by the holders of shares of
                SDG&E Common Stock on the receipt of shares of ParentCo Common
                Stock solely in exchange for shares of SDG&E Common Stock.

         (2)    The basis of shares of ParentCo Common Stock received by the
                holders of shares of SDG&E Common Stock will be the same as the
                basis of the shares of SDG&E Common Stock exchanged for them.

         (3)    As to each holder of shares of SDG&E Common Stock who held his
                or her shares as a capital asset, the holding period of shares
                of ParentCo Common Stock will include the holding period of the
                shares of SDG&E Common Stock exchanged for them.

         (4)    No gain or loss will be recognized by ParentCo upon the issuance
                of shares of ParentCo Common Stock in exchange for shares of
                SDG&E Common Stock.
    
         The advice of Pillsbury Madison & Sutro summarized above is conditioned
      on the receipt by SDG&E of a private letter ruling from the Internal
      Revenue Service to the effect that (i) the formation of MergeCo and the
      Merger will be disregarded for federal income tax purposes, and (ii) the
      transaction will be treated as a transfer by the holders of SDG&E Common
      Stock of such SDG&E Common Stock to ParentCo solely in exchange for an
      equal number of shares of ParentCo Common Stock.  SDG&E has applied for,
      but not yet received, such a ruling.  SDG&E reserves the right to proceed
      with the Merger and related restructuring in the absence of such a ruling
      if, in the opinion of SDG&E's management, all necessary approvals in
      connection with the Merger have been obtained and Pillsbury Madison &
      Sutro removes receipt of such a ruling as a condition to its opinion.
     
         Holders of SDG&E Common Stock or SDG&E Cumulative Preferred Stock who
      contemplate dissenting from the Merger should consult with their tax
      advisors concerning the tax consequences of that action.
    
         The United States federal income tax discussion set forth above is
      based upon current law and is intended for general information only.  The
      foregoing is not intended to be a comprehensive discussion of all possible
      federal income tax consequences of the Merger.  Furthermore, the
      registration statement of which this Proxy Statement and Prospectus is a
      part does not provide information regarding the tax consequences of the
      Merger under the tax laws of any state or of any local or foreign
      jurisdiction.  Holders of SDG&E Common Stock are urged to consult their
      own tax advisors with respect to specific tax consequences of the Merger.

      Legal Opinion

         Pillsbury Madison & Sutro, as counsel for SDG&E and ParentCo, has
      rendered an opinion (filed as an exhibit to the registration statement of
      which this Proxy Statement and Prospectus is a part) to the effect that
      the ParentCo Common Stock offered in this Proxy Statement and Prospectus
      will be validly issued, fully paid and nonassessable.

    
                      ITEM NO. 3 - AMENDMENT OF 1986 LTIP
                      -----------------------------------
      (Item 3 on Common Stock and Cumulative Preferred Stock Proxy Cards)      

    
      General      
    
         On October 24, 1994, the Board of Directors amended, restated and
      extended SDG&E's 1986 Long-Term Incentive Plan (the "LTIP") subject to
      approval by the Shareholders at the Annual Meeting to: (i) permit
      incentive stock options under Section 422 of the Internal Revenue Code
      (the "Code") to be granted from the shares subject to the LTIP; (ii)
      extend the term until April 24, 2005; (iii) include technical changes to
      conform the LTIP to certain deductibility requirements of Section 162(m)
      of the Code as described below and to Rule 16b-3 under the Exchange Act;
      (iv) add provisions for the automatic grant of 300 shares of SDG&E Common
      Stock per year to each non-employee Director (to become shares of parent
      holding company common stock if the proposed formation of a holding
      company structure for SDG&E is approved and implemented); and (v) make
      certain other, technical changes.      
    
         These changes will be effective upon their approval by the
      Shareholders. The amendment, restatement and extension of the LTIP does
      not increase the number of shares available for grant under the LTIP above
      the number previously approved by the Shareholders.      
    
         In 1993, the Code was amended to add Section 162(m). Section 162(m)
      places a limit of $1,000,000 on the amount of compensation that may be
      deducted by SDG&E in any tax year with respect to each of SDG&E's highest
      paid executives, including compensation relating to exercise of LTIP
      awards. However, such compensation arising from stock options and stock
      appreciation rights is not subject to the limit and may be deducted if
      certain limitations approved by the Shareholders are applied to awards
      granted to executives. In order to permit deductibility of compensation
      relating to certain types of awards granted to executive officers, SDG&E
      is requesting the Shareholders to approve the amendments to the LTIP
      relative to Section 162(m) at the Annual Meeting.      
    
      Purpose      
    
         The purpose of the amended and restated LTIP is to promote the
      interests of SDG&E and its Shareholders by encouraging key individuals to
      acquire stock or to increase their proprietary interest in SDG&E. By
      providing the opportunity to acquire stock or receive other incentives,
      SDG&E seeks to attract and retain those key employees upon whose judgment,
      initiative and leadership the success of SDG&E largely depends. While the
      number of individuals receiving      

                                       47
<PAGE>
 
    
      discretionary grants under the LTIP has declined in recent years, and the
      maximum number of shares available for award (which has remained constant
      since inception) is modest in comparison to the total number of shares of
      SDG&E Common Stock outstanding, the Board of Directors believes that the
      LTIP remains an important means of compensating key employees.      
    
      Shares Subject to LTIP      
    
         There are 2,700,000 shares of SDG&E Common Stock reserved for issuance
      under the amended and restated LTIP. As of the Record Date, 2,201,540
      shares of SDG&E Common Stock remained available for issuance.      
    
      Description of LTIP      
    
         The full text of the amended and restated LTIP, substantially in the
      form in which it will take effect if the modifications are approved by the
      Shareholders, is set forth as Exhibit D to this Proxy Statement and
      Prospectus. The following summary of the principal features of the LTIP is
      subject to, and qualified in its entirety by, Exhibit D.      
    
         Administration      
         --------------
    
         The LTIP will be administered by a Committee. Currently the Committee
      consists of the Executive Compensation Committee of the Board of Directors
      (presently comprising C. T. Fitzgerald, Chair, R. H. Goldsmith and D. W.
      Derbes). The Board of Directors may fill vacancies from time to time to
      remove or add members. All members of the Committee must be disinterested
      persons under Rule 16b-3 of the Exchange Act ("Rule 16b-3"). Modifications
      reflected in the LTIP will permit members of the Committee to receive
      automatic annual grants of Common Stock in accordance with Rule 16b-3, as
      described below.      
    
         The Committee selects those employees of SDG&E or its subsidiaries who
      will be eligible to receive awards under the LTIP. Currently there are 11
      employees participating in the LTIP. The LTIP provides that the Committee
      may grant to eligible individuals any combination of nonqualified stock
      options, incentive stock options, restricted stock, stock appreciation
      rights, performance awards, stock payments or dividend equivalents. Each
      grant will be memorialized in a separate agreement with the person
      receiving the grant. This agreement will indicate the type and terms of
      the award. The participation of non-employee Directors of SDG&E is limited
      to automatic annual grants of SDG&E Common Stock, as described below. 
     
    
         Non-Employee Director Formula Grants      
         ------------------------------------
    
         Non-employee Directors are not eligible to receive awards under the
      LTIP other than an annual grant of 300 shares of Common Stock (subject to
      anti-dilution adjustments). These grants are designed to comply with the
      provisions of Rule 16b-3 and are made at the conclusion of each regular
      annual meeting of Shareholders to incumbent non-employee Directors who
      will continue to serve on the Board of Directors thereafter. The shares of
      Common Stock will be issued for past service by the non-employee Directors
      and without payment of any purchase price. Partial year service will be
      prorated accordingly. Assuming the amendment and      

                                       48
<PAGE>
 
    
      restatement of the LTIP is approved by the Shareholders, each incumbent
      non-employee Director will receive a grant of 300 shares of Common Stock
      effective upon the conclusion of the Annual Meeting.      
    
         Stock Options      
         -------------
    
         Nonqualified stock options will provide for the right to purchase
      shares of Common Stock at a price which is not less than 100% of the fair
      market value of the Common Stock subject to the option on the effective
      date of the grant. These options will be granted for a term which may not
      exceed ten years.      
    
         Incentive stock options will be designed to comply with the provisions
      of the Code, and will be subject to restrictions contained in the Code.
      Incentive stock options will be granted with an exercise price of not less
      than 100% of the fair market value of the Common Stock subject to the
      option on the date of grant and will extend for a term of up to ten years.
      Incentive stock options granted to persons who own more than 10% of the
      combined voting power of SDG&E's outstanding securities must be granted at
      prices which are not less than 110% of fair market value on the date of
      grant and may not extend for more than five years from the date of grant.
      The closing price per share of SDG&E Common Stock as reported on the New
      York Stock Exchange on February [__], 1995 was [$_____].      
    
         The option exercise price must be paid in full at the time of exercise.
      The price may be paid in cash or, as acceptable to the Committee, by loan
      made by SDG&E to the participant, by arrangement with a broker where
      payment of the option price is guaranteed by the broker, by the surrender
      of shares of SDG&E owned by the participant exercising the option and
      having a fair market value on the date of exercise equal to the option
      price, or by any combination of the foregoing equal to the option price.
     
    
         Options for employees will have such other terms and be exercisable in
      such manner and at such times as the Committee may determine. An option
      agreement for an employee may provide for accelerated exercisability in
      the event of the employee's death, disability or retirement or other
      events in accordance with policies established by the Committee.      
    
         The Committee may, at any time prior to exercise and subject to consent
      of the participant, amend, modify or cancel any option previously granted
      and may or may not substitute in their place options at a different price
      and of a different type under different terms or in different amounts. 
     
    
         Restricted Stock      
         ----------------
    
         Restricted stock may be granted or sold to employees for prices
      determined by the Committee (subject to a minimum of $2.50 per share) and
      subject to such restrictions as may be appropriate. It is anticipated that
      restricted stock would be forfeited and would be resold to SDG&E at cost
      in the event that "vesting" is not achieved by virtue of seniority or
      performance or other criteria. In general, restricted shares may not be
      sold, transferred or hypothecated until      

                                       49
<PAGE>
 
    
      restrictions are removed or expire. Purchasers of restricted stock, unlike
      recipients of options, will have voting rights and will receive dividends
      prior to the time when the restrictions lapse.      
    
         Stock Appreciation Rights      
         -------------------------
    
         Stock appreciation rights ("SARs") may be granted in tandem with stock
      options or separately. If SARs are granted in tandem with options, the
      options may be either nonqualified or incentive stock options. SARs
      granted by the Committee in tandem with stock options will provide for
      payments to grantees based upon increases in the price of the Common Stock
      over the exercise price of the related option. The SARs will provide that
      the holder of the SARs may exercise the SARs or the option in whole or in
      part, but the aggregate exercise may not cover more than the aggregate
      number of shares upon which the value of the SARs is based. SARs granted
      in tandem with options may not extend beyond the term of the related
      option. SARs will be transferable only to the extent that the related
      option is transferable. The Committee may elect to pay SARs in cash or in
      Common Stock or in a combination of cash and Common Stock.      
    
         SARs which are issued separately from options will provide for payments
      based upon increases in the price of the Common Stock over the fair market
      value of the Common Stock or the book value of the Common Stock on the
      date of grant. The Committee will determine whether fair market value or
      book value will be the appropriate measure. As with other SARs, upon
      exercise the Committee may determine to pay the SARs in cash or in Common
      Stock or in a combination of cash and Common Stock.      
    
         Performance Awards, Common Stock Payments and Dividend Equivalents 
         ------------------------------------------------------------------
     
    
         Performance awards may be granted by the Committee on an individual
      basis.  Generally these awards will be paid in cash and will be based upon
      specific agreements.      
    
         The Committee may approve a payment in Common Stock to any employee who
      otherwise may be entitled to a cash payment other than base salary (e.g.,
                                                                          ---- 
      a bonus).  Similarly, the Committee may award shares as dividend
      equivalents with respect to grants of options or SARs.      
    
         Section 162(m)      
         --------------
    
         In order to permit maximum deductibility of compensation relating to
      awards of stock options and SARs, a limitation has been imposed upon the
      number of such awards which may be made under the LTIP.  Specifically, no
      more than an aggregate of 270,000 shares of Common Stock shall be subject
      to stock options and SARs that are granted under the amended and restated
      LTIP to any one employee on or before April 24, 2005.  A maximum of
      2,700,000 shares may be awarded to all employees under the amended and
      restated LTIP.      
    
         Other Provisions      
         ----------------
    
         The amended and restated LTIP contains customary provisions relating to
      adjustments for increases or decreases in the number and kind of SDG&E's
      securities.  The Committee may      

                                       50
<PAGE>
 
    
      periodically adopt rules and regulations for purposes of carrying out the
      amended and restated LTIP.      
    
         The amended and restated LTIP will expire on April 24, 2005, unless it
      is terminated before then by the Board of Directors.      
    
         The Board of Directors may amend, suspend or terminate the amended and
      restated LTIP at any time without further action of the Shareholders
      except as required by applicable law.      
    
      Federal Income Tax Consequences      
    
         The following discussion of the federal income tax consequences of the
      amended and restated LTIP as it relates to nonqualified stock options,
      incentive stock options and share awards is intended to be a summary of
      applicable federal law.  State and local tax consequences may differ. 
     
    
         Options      
         -------
    
         Incentive stock options and nonqualified stock options are treated
      differently for federal income tax purposes.  Incentive stock options are
      intended to comply with the requirements of Section 422 of the Code.
      Nonqualified stock options need not comply with such requirements.      
    
         An optionee is not taxed on the grant or exercise of an incentive stock
      option.  The difference between the exercise price and the fair market
      value of the shares on the exercise date will, however, be a preference
      item for purposes of the alternative minimum tax.  If an optionee holds
      the shares acquired upon exercise of an incentive stock option for at
      least two years following grant and at least one year following exercise,
      the optionee's gain, if any, upon a subsequent disposition of such shares
      is long-term capital gain.  The measure of the gain is the difference
      between the proceeds received on disposition and the optionee's basis in
      the shares (which generally equals the exercise price).  If an optionee
      disposes of stock acquired pursuant to exercise of an incentive stock
      option before satisfying the one and two-year holding periods described
      above, the optionee will recognize both ordinary income and capital gain
      in the year of disposition.  The amount of the ordinary income will be the
      lesser of (i) the amount realized on disposition less the optionee's
      adjusted basis in the stock (usually the option price) or (ii) the
      difference between the fair market value of the stock on the exercise date
      and the option price.  The balance of the consideration received on such a
      disposition will be long-term capital gain if the stock had been held for
      at least one year following exercise of the incentive stock option.  SDG&E
      is not entitled to an income tax deduction on the grant or exercise of an
      incentive stock option or on the optionee's disposition of the shares
      after satisfying the holding period requirement described above.  If the
      holding periods are not satisfied, SDG&E will be entitled to a deduction
      in the year the optionee disposes of the shares, in an amount equal to the
      ordinary income recognized by the optionee.      
    
         An optionee is not taxed on the grant of a nonqualified stock option.
      On exercise, however, the optionee recognizes ordinary income equal to the
      difference between the option price and the fair market value of the
      shares on the date of exercise.  SDG&E is entitled to an income      

                                       51
<PAGE>
 
    
      tax deduction in the year of exercise in the amount recognized by the
      optionee as ordinary income.  Any gain on subsequent disposition of the
      shares is long-term capital gain if the shares are held for at least one
      year following exercise.  SDG&E does not receive a deduction for this
      gain.      
     
           Share Awards      
           ------------
    
         If a participant is awarded or purchases shares, the amount by which
      the fair market value of the shares on the date of award or purchase
      exceeds the amount paid for the shares will be taxed to the participant as
      ordinary income.  SDG&E will be entitled to a deduction in the same amount
      provided it makes all required withholdings on the compensation element of
      the sale or award.  The participant's tax basis in the shares acquired is
      equal to the share's fair market value on the date of acquisition.  Upon a
      subsequent sale of any shares, the participant will realize capital gain
      or loss (long-term or short-term, depending on whether the shares were
      held for more than one year before the sale) in an amount equal to the
      difference between his or her basis in the shares and the sale price. 
     
    
         If a participant is awarded or purchases shares that are subject to a
      vesting schedule, the participant is deemed to receive an amount of
      ordinary income equal to the excess of the fair market value of the shares
      at the time they vest over the amount (if any) paid for such shares by the
      participant.  SDG&E is entitled to a deduction equal to the amount of the
      income recognized by the participant.      
    
         Code Section 83(b) permits a participant to elect, within 30 days after
      the transfer of any shares subject to a vesting schedule to him or her, to
      be taxed at ordinary income rates on the excess of the fair market value
      of the shares at the time of the transfer over the amount (if any) paid by
      the participant for such shares.  Withholding taxes apply at that time.
      If the participant makes a Section 83(b) election, any later appreciation
      in the value of the shares is not taxed as ordinary income, but instead is
      taxed as capital gain when the shares are sold or transferred.      
    
         Grants of shares to Non-employee Directors are deemed subject to a
      vesting schedule for six months from the date of grant, and absent a
      Section 83(b) election to be taxed on the date of grant, the shares will
      not be taxed until six months from the date of grant.  The shares are
      deemed subject to a vesting schedule because of the "short-swing profits"
      provisions of Section 16(b) of the Exchange Act.  No withholding taxes
      apply to shares granted to Non-employee Directors.      
    
      Amended LTIP Benefits      
    
         The Committee has full discretion to determine the number, type and
      value of awards to be granted to key employees under the LTIP.  Therefore,
      the benefits and amounts that will be received by each of the named
      executive officers, the executive officers as a group and all other key
      employees are not determinable.  Details on incentive awards granted
      during the last three years to the named executive officers are presented
      above under "Item No. 1 - Election of Directors--Executive Compensation
      and Transactions with Management and Others, --Summary Compensation Table
      and --1986 Long-Term Incentive Plan."      

                                       52
<PAGE>
 
    
         The number of shares of Common Stock to be received by each non-
      employee Director is fixed under the LTIP, as discussed above, and may not
      be amended more frequently than once every six months.      
    
      Company Recommendation      
    
         The Board has unanimously approved the amended and restated LTIP and
      recommends that Shareholders vote "FOR" the approval of the amended and
      restated LTIP.      
    
         In order to be adopted, the amended and restated LTIP must be approved
      by a majority of the combined classes of SDG&E Common Stock and SDG&E
      Cumulative Preferred Stock present, or represented, and entitled to vote
      at the Annual Meeting, with each share of SDG&E Common Stock being
      entitled to one vote and each share of SDG&E Cumulative Preferred Stock
      being entitled to two votes.  An abstention, or shares represented by
      proxies which are marked "ABSTAIN," will have the same effect as a vote
      against the proposal.  The failure of a broker or other nominee to vote
      shares for a beneficial owner will have no effect on the proposal.      
    
      Effect of Implementation of Holding Company Structure      
    
         Upon completion of the reorganization of SDG&E as a subsidiary of a
      parent holding company, such parent holding company will assume and
      continue the amended and restated LTIP and all of the shares of SDG&E
      Common Stock set aside under the LTIP will become shares of common stock
      of such parent holding company.  By approving the formation of a parent
      holding company, the Shareholders will be deemed to have approved the
      actions necessary to effect the assumption of the LTIP by such parent
      holding company.

                       ITEM NO. 4 - SHAREHOLDER PROPOSAL
                       ---------------------------------
      (Item 4 on Common Stock and Cumulative Preferred Stock Proxy Cards)      

    
         SDG&E has received the following shareholder proposal submitted in
      accordance with the rules of the SEC.  This proposal will be voted upon at
      the Annual Meeting only if properly presented by the proposing
      shareholders or their qualified representative.  To be approved, the
      proposal must receive the affirmative vote of a majority of the
      outstanding shares of SDG&E Common Stock and SDG&E Cumulative Preferred
      Stock represented and voting at the Annual Meeting (with shares of SDG&E
      Common Stock having one vote per share and shares of SDG&E Cumulative
      Preferred Stock having two votes per share).      
    
         The proposal and supporting statement are presented as received by
      SDG&E and the Board of Directors disclaims any responsibility for their
      content.  The Board of Directors recommends a vote "AGAINST" the proposal
      for the reasons stated in the opposition statement following the proposal.
      The name and address of and number of shares represented to be held by the
      proposing shareholders will be furnished by SDG&E to any Shareholder
      promptly upon receipt of any oral or written request to the Secretary of
      SDG&E.      
    
      Shareholder Proposal      
    
        "RESOLVED:  That the shareholders  recommend that the Board of Directors
        institute the additional criteria that shareholders must receive a total
        return of 9% in the fiscal year before any consideration is given to
        officer options and bonus."      
    
         "Reasons:  Under the present system the officers may be awarded options
      at $2.50 a share, and thus make a substantial profit even when the
      shareholders have a negative return.  The Directors have set a criteria
      for bonus and option award that cannot be evaluated by the shareholders."
     
    
      SDG&E Opposition Statement      
    
         The Board agrees that the compensation of SDG&E's officers should be
      tied to the financial performance of the Company.  Indeed, the Company's
      current long and short-term incentive compensation programs are based upon
      achievement of financial and operational goals, which in turn, enhance
      Shareholder value.  For the reasons discussed below, however, the Board
      does not believe that total return to shareholders is an appropriate
      criteria for officer compensation.      
    
         Two components impact shareholder return:  dividends and appreciation
      in the market price of the Company's stock.  Dividends clearly depend on
      the financial performance of the Company.  Stock price, however, is
      subject to varying economic, industry and market forces which are totally
      outside the scope of management's control.  These divergent forces can and
      do cause significant price changes, up and down, among various stocks and
      stock groups.      
    
         Although previous goals under the Company's Long-Term Incentive Plan
      (LTIP) have included total shareholder return, your Board no longer uses
      it to determine incentive      

                                       54
<PAGE>
 
    
      compensation.  A total shareholder return goal can operate capriciously to
      penalize or reward management and can do so for reasons entirely beyond
      management's control.  The Board believes that its existing compensation
      programs, which are tied to specific performance goals including earnings
      growth, provide the right type of incentive for the Company's officers.
     
    
         The Board urges each shareholder to review the more full discussion of
      the Company's executive compensation programs and its "pay for
      performance" approach included above in this Proxy Statement and
      Prospectus (see "Item No. 1 - Election of Directors--Executive
      Compensation and Transactions with Management and Others" and "--Report of
      the Executive Compensation Committee").      
    
         FOR THESE REASONS, THE BOARD OF DIRECTORS RECOMMENDS THAT THE
      SHAREHOLDERS VOTE "AGAINST" THIS PROPOSAL.  Proxies received will be voted
      against this proposal unless a contrary choice is specified.      

    
      Experts/Relationship with Independent Public Accountant      
    
         The consolidated financial statements and the related financial
      statement schedules as of December 31, 1993 and 1992 and for each of the
      three years in the period ended December 31, 1993, incorporated in this
      Proxy Statement and Prospectus by reference from the Company's Annual
      Report on Form 10-K for 1993, as amended, have been audited by Deloitte &
      Touche LLP, independent auditors, as stated in their report, which is
      incorporated herein by reference (which report contains an emphasis
      paragraph referring to the Company's consideration of alternative
      strategies for its 80 percent owned subsidiary, Wahlco Environmental
      Systems, Inc.), and has been so incorporated in reliance upon the report
      of such firm given upon their authority as experts in accounting and
      auditing.     
    
         Deloitte & Touche LLP (or its predecessor firm, Deloitte Haskins &
      Sells) has been employed regularly by SDG&E for many years to audit its
      financial statements and for other purposes.  Representatives of Deloitte
      & Touche LLP are expected to be present at the Annual Meeting.  They will
      have the opportunity to make a statement, if they so desire, and will
      respond to appropriate questions from Shareholders.      

    
      Annual Report and Availability of Form 10-K      
    
         SDG&E's 1994 Annual Report to Shareholders accompanies this Proxy
      Statement and Prospectus.  SDG&E's Annual Report to the SEC on Form 10-K
      for 1994, which is incorporated into this Proxy Statement and Prospectus
      by reference, will be provided to Shareholders, without charge, upon
      written request to N. A. Peterson, Office of the Secretary, San Diego Gas
      & Electric Company, P.O. Box 1831, San Diego, California 92112-4150.

      Shareholder Proposals for 1996 Annual Meeting      
    
         Proposals that Shareholders may wish to have included in the proxy
      materials relating to the next annual meeting must be received by SDG&E by
      November 10, 1995.  If the Merger has been effected prior to such time,
      Shareholder proposals should be addressed to ParentCo.      

      Proxy Solicitations
    
         In addition to the original solicitation by mail, some of the officers
      and regular employees of SDG&E may solicit proxies by personal visits,
      telephone or mail without receiving compensation in addition to their
      regular salaries.  SDG&E anticipates that the expense associated with
      these solicitation efforts will be nominal.  SDG&E will reimburse
      brokerage firms and other securities' custodians for reasonable expenses
      incurred by them in forwarding proxy material to beneficial owners of
      stock.      

         SDG&E has also retained Georgeson & Co., Inc., a proxy solicitation
      firm, to assist in the solicitation of proxies at an estimated cost of
      $12,000 plus disbursements.  All costs associated with this solicitation
      will be borne by SDG&E.
    
      Other Business to be Brought Before the Annual Meeting      
    
         The Board of Directors does not know of any matters that will be
      presented for action at the Annual Meeting other than the matters
      described above.  However, if any other matters properly come before the
      Annual Meeting, the holders of proxies solicited by the Board of Directors
      will vote on those matters in accordance with their judgment, and
      discretionary authority to do so is included in the proxy.

                              AGREEMENT OF MERGER
                              -------------------


         THIS AGREEMENT OF MERGER ("Agreement") is made as of [__________],
      1995, by and among SAN DIEGO GAS & ELECTRIC COMPANY, a California
      corporation ("SDG&E"), SAN DIEGO MERGER COMPANY, a California corporation
      ("MergeCo"), and SDO PARENT CO., INC., a California corporation
      ("ParentCo"), with reference to the following facts:

         A.  SDG&E has authorized capital consisting of (i) 255 million shares
      of Common Stock, without par value ("SDG&E Common Stock"), of which
      approximately 116,541,000 shares are issued and outstanding; (ii)
      1,375,000 shares of Cumulative Preferred Stock, $20 par value ("Cumulative
      Preferred Stock"), of which 1,374,650 shares (consisting of four separate
      series) are issued and outstanding; and (iii) 10 million shares of
      Preference Stock (Cumulative), without par value ("Preference Stock"), of
      which 3,190,000 shares (consisting of four separate series) are issued and
      outstanding.

         B.  MergeCo has authorized capital consisting of 1000 shares of Common
      Stock ("MergeCo Common Stock"), of which 100 shares are issued and
      outstanding and owned beneficially and of record by ParentCo.

         C.  ParentCo has authorized capital consisting of 300 million shares of
      Common Stock ("ParentCo Common Stock"), of which 100 shares are issued and
      outstanding and owned beneficially and of record by SDG&E, and 30 million
      shares of Preferred Stock, none of which have been issued.

         D.  The Boards of Directors of the respective parties hereto deem it
      advisable to merge MergeCo with and into SDG&E (the "Merger") in
      accordance with the California General Corporation Law ("California GCL")
      and this Agreement for the purpose of establishing ParentCo as the parent
      corporation for SDG&E in a transaction intended to qualify for tax-free
      treatment.

         NOW, THEREFORE, in consideration of the premises and agreements
      contained herein, the parties agree that (i) MergeCo shall be merged with
      and into SDG&E (the "Merger"), (ii) SDG&E shall be the corporation
      surviving the Merger, and (iii) the terms and conditions of the Merger,
      the mode of carrying it into effect, and the manner of converting and
      exchanging shares of capital stock shall be as follows:

                                   ARTICLE 1

                                   The Merger
                                   ----------
    
         1.1  Officers' Certificates.  Subject to and in accordance with the
              ----------------------                                        
      provisions of this Agreement, officers' certificates of SDG&E and MergeCo
      (the "Officers'      

                                      A-1
<PAGE>
 
      Certificates") shall be signed and verified and thereafter delivered,
      together with a copy of this Agreement, to the office of the Secretary of
      State of California for filing, all as provided in Section 1103 of the
      California GCL.

         1.2  Effective Time.  The Merger shall become effective at 11:59 p.m.
              --------------                                                  
      on the last day of the calendar month during which the Officers'
      Certificates and this Agreement are filed with the Secretary of State of
      California as contemplated by Section 1.1 above (the "Effective Time").
      At the Effective Time, the separate existence of MergeCo shall cease and
      MergeCo shall be merged with and into SDG&E, which shall continue its
      corporate existence as the surviving corporation (SDG&E and MergeCo being
      sometimes referred to herein as the "Constituent Corporations" and SDG&E,
      as the surviving corporation, being sometimes referred to herein as the
      "Surviving Corporation").  SDG&E shall succeed, without other transfer, to
      all the rights and property of MergeCo and shall be subject to all the
      debts and liabilities of MergeCo in the same manner as if SDG&E had itself
      incurred them.  All rights of creditors and all liens upon the property of
      each of SDG&E and MergeCo shall be preserved unimpaired.

         1.3  Appropriate Actions.  Prior to and after the Effective Time,
              -------------------                                         
      ParentCo, SDG&E and MergeCo, respectively, shall take all such actions as
      may be necessary or appropriate in order to effectuate the Merger.  In
      this connection, ParentCo shall issue the shares of ParentCo Common Stock
      into which outstanding shares of SDG&E Common Stock will be converted on a
      share-for-share basis to the extent provided in Article 2 of this
      Agreement.  In case at any time after the Effective Time any further
      action is necessary or desirable to carry out the purposes of this
      Agreement and to vest the Surviving Corporation with full title to all
      properties, assets, privileges, rights, immunities and franchises of
      either of the Constituent Corporations, the officers and directors of each
      of the Constituent Corporations as of the Effective Time shall take all
      such further action.

                   Terms of Conversion and Exchange of Shares
                   ------------------------------------------

      At the Effective Time:

         2.1  SDG&E Common Stock.  Each share of SDG&E Common Stock issued and
              ------------------                                              
      outstanding immediately prior to the Merger shall be automatically changed
      and converted into one share of ParentCo Common Stock, which shall
      thereupon be issued and fully-paid and non-assessable; provided, however,
                                                             --------  ------- 
      that such conversion shall not affect shares of holders, if any, who
      perfect their rights as dissenting shareholders under Chapter 13 of the
      California GCL.

         2.2  SDG&E Preferred Stock.  Shares of the Cumulative Preferred Stock
              ---------------------                                           
      and Preference Stock of SDG&E issued and outstanding immediately prior to
      the Merger shall not be converted or otherwise affected by the Merger.
      Each such share shall continue to be (i) issued and outstanding and (ii) a
      fully-paid and nonassessable share (of Cumulative Preferred Stock or
      Preference Stock, as the case may be) of the Surviving Corporation.

                              SDO PARENT CO., INC.


      FIRST:  The name of the Corporation is SDO Parent Co., Inc.
      -----                                                      


      SECOND:  The purpose of the Corporation is to engage in any lawful act or
      ------                                                                   
      activity for which a corporation may be organized under the General
      Corporation Law of California other than the banking business, the trust
      company business or the practice of a profession permitted to be
      incorporated by the California Corporations Code.


      THIRD:  Stock.
      -----         

         A.  The Corporation is authorized to issue two classes of shares, to be
      designated respectively Preferred Stock ("Preferred Stock") and Common
      Stock ("Common Stock").  The total number of shares of capital stock that
      the Corporation is authorized to issue is 330,000,000, of which 30,000,000
      shall be Preferred Stock and 300,000,000 shall be Common Stock.

         B.  The Preferred Stock may be issued from time to time in one or more
      series.  The Board of Directors of the Corporation (the "Board of
      Directors") is expressly authorized to provide for the issue of all or any
      of the shares of the Preferred Stock in one or more series, and to fix the
      designation and number of shares and to determine or alter for each such
      series, such voting powers, full or limited, or no voting powers, and such
      designations, preferences and relative, participating, optional or other
      rights and such qualifications, limitations or restrictions thereof, as
      shall be stated and expressed in the resolution or resolutions adopted by
      the Board of Directors providing for the issue of such shares and as may
      be permitted by the General Corporation Law of California.  The Board of
      Directors is also expressly authorized to increase or decrease (but not
      below the number of shares of such series then outstanding) the number of
      shares of any series subsequent to the issue of shares of that series.  If
      the number of shares of any such series shall be so decreased, the shares
      constituting such decrease shall resume the status that they had prior to
      the adoption of the resolution originally fixing the number of shares of
      such series.


      FOURTH:  Directors.
      ------             

         A.  The authorized number of directors of the Corporation shall not be
      fewer than nine (9) nor more than thirteen (13).  The exact authorized
      number of directors shall be fixed from time to time, within the limits
      specified in this Article FOURTH, by resolution of the Board of Directors,
      or by a bylaw or amendment thereof duly adopted by the Board of Directors
      or the

                                      B-1
<PAGE>
 
      affirmative vote of the holders of shares representing at least 66-2/3% of
      the outstanding shares of the Corporation entitled to vote.

         B.  The Board of Directors shall be divided into three classes,
      designated Class I, Class II and Class III, as nearly equal in number as
      possible, and the term of office of directors of one class shall expire at
      each annual meeting of shareholders, but in all cases continue as to each
      director until his or her successor shall be elected and shall qualify or
      until his or her earlier resignation, removal from office, death or
      incapacity.  Additional directorships resulting from an increase in number
      of directors shall be apportioned among the classes as equally as
      possible.  The initial terms of office shall be determined by resolution
      duly adopted by the Board of Directors.  At each annual meeting of
      shareholders the number of directors equal to the number of directors of
      the class whose term expires at the time of such meeting (or, if fewer,
      the number of directors properly nominated and qualified for election)
      shall be elected to hold office until the third succeeding annual meeting
      of shareholders after their election.  This Paragraph B of this Article
      FOURTH shall become effective only when the Corporation shall have become
      a "listed corporation" within the meaning of section 301.5 of the
      California Corporations Code.

         C.  Vacancies in the Board of Directors, including, without limitation,
      vacancies created by the removal of any director, may be filled by a
      majority of the directors then in office, whether or not less than a
      quorum, or by a sole remaining director.


      FIFTH:  No shareholder may cumulate votes in the election of directors.
      -----                                                                   
      This Article FIFTH shall become effective only when the Corporation shall
      have become a "listed corporation" within the meaning of section 301.5 of
      the California Corporations Code.


      SIXTH:  Unless the Board of Directors, by a resolution adopted by 66-2/3%
      -----                                                                    
      of the authorized number of directors, waives the provisions of this
      Article SIXTH in any particular circumstance, any action required or
      permitted to be taken by shareholders of the Corporation must be taken
      either (i) at a duly called annual or special meeting of shareholders of
      the Corporation or (ii) by the unanimous written consent of all of the
      shareholders.


      SEVENTH:  Fair Price.
      -------              

         A. REQUIRED SHAREHOLDER VOTE FOR CERTAIN TRANSACTIONS.

           Unless all of the conditions set forth in either Subsection 1 or 2 of
      Section B of this Article SEVENTH have been fulfilled, any agreement,
      contract, transaction or other arrangement providing for or resulting in a
      Business Combination must be approved by the affirmative vote of 66-2/3%
      of the number of shares of Common Stock outstanding at the time voting as
      a separate class.  Such affirmative vote shall be required notwithstanding
      the fact that no vote may be required by law or these Articles or that a
      lesser percentage, different or additional vote may be specified by law,
      these Articles, or in any agreement with any national

                                      B-2

      securities exchange or otherwise, in which case each vote requirement
      shall be satisfied individually.

         B.  EXCEPTIONS.

           Section A of this Article SEVENTH shall not apply to any Business
      Combination if the conditions specified in either Subsection 1 or 2 below
      are met.

           1.   The Business Combination shall have been approved by a
      resolution adopted by 66-2/3% of the authorized number of directors of the
      Corporation, or

           2.   All of the following conditions have been met:

                a. Any consideration to be received for any stock as a result of
                the Business Combination shall be in cash or in the same form as
                a Dominant Shareholder has previously paid for shares of that
                class.  If varying forms of consideration have been used, the
                form of consideration shall be the form used to acquire the
                largest number of shares of the class receiving consideration.

                b. The aggregate amount of cash and the fair market value of any
                other form of consideration shall, on a per share basis, be at
                least equal to the Highest Purchase Price paid by a Dominant
                Shareholder for shares of the same class.

                c. After such Dominant Shareholder has become a Dominant
                Shareholder and prior to the consummation of such Business
                Combination:

                     (1) There shall have been no failure to declare and pay in
                     full at the regular rate any periodic dividends on any
                     outstanding preferred stock unless such failure is approved
                     by 66-2/3% of the authorized number of directors of the
                     Corporation;

                     (2) There shall have been no reduction in the quarterly
                     rate of dividends, if any, paid on common shares (such rate
                     to be appropriately adjusted to reflect the occurrence of
                     any reclassification, reverse stock split,
                     recapitalization, reorganization or other similar
                     transaction having the effect of changing the number of
                     outstanding common shares) unless such reduction is
                     approved by 66-2/3% of the authorized number of directors
                     of the Corporation; and

                     (3) Neither a Dominant Shareholder nor an Affiliate thereof
                     shall have acquired Beneficial Ownership of any additional
                     shares of voting stock of the Corporation except as part of
                     a transaction which has been approved by a resolution
                     adopted by 66-2/3% of the authorized number of directors.

        Exhibit C - Chapter 13 of the California General Corporation Law

                               DISSENTERS' RIGHTS

      (S) 1300.  Reorganization or short-form merger; dissenting shares;
                 corporate purchase at fair market value; definitions

         (a) If the approval of the outstanding shares (Section 152) of a
      corporation is required for a reorganization under subdivisions (a) and
      (b) or subdivision (e) or (f) of Section 1201, each shareholder of the
      corporation entitled to vote on the transaction and each shareholder of a
      subsidiary corporation in a short-form merger may, by complying with this
      chapter, require the corporation in which the shareholder holds shares to
      purchase for cash at their fair market value the shares owned by the
      shareholder which are dissenting shares as defined in subdivision (b).
      The fair market value shall be determined as of the day before the first
      announcement of the terms of the proposed reorganization or short-form
      merger, excluding any appreciation or depreciation in consequence of the
      proposed action, but adjusted for any stock split, reverse stock split, or
      share dividend which becomes effective thereafter.

         (b) As used in this chapter, "dissenting shares" means shares which
      come within all of the following descriptions:

             (1) Which were not immediately prior to the reorganization or 
      short-form merger either (A) listed on any national securities exchange
      certified by the Commissioner of Corporations under subdivision (o) of
      Section 25100 or (B) listed on the list of OTC margin stocks issued by the
      Board of Governors of the Federal Reserve System, and the notice of
      meeting of shareholders to act upon the reorganization summarizes this
      section and Sections 1301, 1302, 1303 and 1304; provided, however, that
      this provision does not apply to any shares with respect to which there
      exists any restriction on transfer imposed by the corporation or by any
      law or regulation; and provided, further, that this provision does not
      apply to any class of shares described in subparagraph (A) or (B) if
      demands for payment are filed with respect to 5 percent or more of the
      outstanding shares of that class.

             (2) Which were outstanding on the date for the determination of
      shareholders entitled to vote on the reorganization and (A) were not voted
      in favor of the reorganization or, (B) if described in subparagraph (A) or
      (B) of paragraph (1) (without regard to the provisos in that paragraph),
      were voted against the reorganization, or which were held of record on the
      effective date of a short-form merger; provided, however, that
      subparagraph (A) rather than subparagraph (B) of this paragraph applies in
      any case where the approval required by Section 1201 is sought by written
      consent rather than at a meeting.

             (3) Which the dissenting shareholder has demanded that the
      corporation purchase at their fair market value, in accordance with
      Section 1301.

             (4) Which the dissenting shareholder has submitted for endorsement,
      in accordance with Section 1302.

                                      C-1

         (c) As used in this chapter, "dissenting shareholder" means the
      recordholder of dissenting shares and includes a transferee of record.

      (S) 1301.  Notice to holders of dissenting shares in reorganizations;
                 demand for purchase; time; contents

         (a) If, in the case of a reorganization, any shareholders of a
      corporation have a right under Section 1300, subject to compliance with
      paragraphs (3) and (4) of subdivision (b) thereof, to require the
      corporation to purchase their shares for cash, such corporation shall mail
      to each such shareholder a notice of the approval of the reorganization by
      its outstanding shares (Section 152) within 10 days after the date of such
      approval, accompanied by a copy of Sections 1300, 1302, 1303, 1304 and
      this section, a statement of the price determined by the corporation to
      represent the fair market value of the dissenting shares, and a brief
      description of the procedure to be followed if the shareholder desires to
      exercise the shareholder's right under such sections.  The statement of
      price constitutes an offer by the corporation to purchase at the price
      stated any dissenting shares as defined in subdivision (b) of Section
      1300, unless they lose their status as dissenting shares under Section
      1309.

         (b) Any shareholder who has a right to require the corporation to
      purchase the shareholder's shares for cash under Section 1300, subject to
      compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who
      desires the corporation to purchase such shares shall make written demand
      upon the corporation for the purchase of such shares and payment to the
      shareholder in cash of their fair market value.  The demand is not
      effective for any purpose unless it is received by the corporation or any
      transfer agent thereof (1) in the case of shares described in clause (i)
      or (ii) of paragraph (1) of subdivision (b) of Section 1300 (without
      regard to the provisos in that paragraph), not later than the date of the
      shareholders' meeting to vote upon the reorganization, or (2) in any other
      case within 30 days after the date on which the notice of the approval by
      the outstanding shares pursuant to subdivision (a) or the notice pursuant
      to subdivision (i) of Section 1110 was mailed to the shareholder.

         (c) The demand shall state the number and class of the shares held of
      record by the shareholder which the shareholder demands that the
      corporation purchase and shall contain a statement of what such
      shareholder claims to be the fair market value of those shares as of the
      day before the announcement of the proposed reorganization or short-form
      merger.  The statement of fair market value constitutes an offer by the
      shareholder to sell the shares at such price.

      (S) 1302.  Submission of share certificates for endorsement;
                 uncertificated securities

         Within 30 days after the date on which notice of the approval by the
      outstanding shares or the notice pursuant to subdivision (i) of Section
      1110 was mailed to the shareholder, the shareholder shall submit to the
      corporation at its principal office or at the office of any transfer agent
      thereof, (a) if the shares are certificated securities, the shareholder's
      certificates representing any shares which the shareholder demands that
      the corporation purchase, to be stamped or endorsed with a statement that
      the shares are dissenting shares to be exchanged for certificates of
      appropriate denomination so stamped or endorsed or (b) if the shares are

                                      C-2
<PAGE>
 
      uncertificated securities, written notice of the number of shares which
      the shareholder demands that the corporation purchase.  Upon subsequent
      transfers of the dissenting shares on the books of the corporation, the
      new certificates, initial transaction statement, and other written
      statements issued therefor shall bear a like statement, together with the
      name of the original dissenting holder of the shares.

      (S) 1303.  Payment of agreed price with interest; agreement fixing fair
                 market value; filing; time of payment

         (a) If the corporation and the shareholder agree that the shares are
      dissenting shares and agree upon the price of the shares, the dissenting
      shareholder is entitled to the agreed price with interest thereon at the
      legal rate on judgments from the date of the agreement.  Any agreements
      fixing the fair market value of any dissenting shares as between the
      corporation and the holders thereof shall be filed with the secretary of
      the corporation.

         (b) Subject to the provisions of Section 1306, payment of the fair
      market value of dissenting shares shall be made within 30 days after the
      amount thereof has been agreed or within 30 days after any statutory or
      contractual conditions to the reorganization are satisfied, whichever is
      later, and in the case of certificated securities, subject to surrender of
      the certificates therefor, unless provided otherwise by agreement.

      (S) 1304.  Action to determine whether shares are dissenting shares or
                 fair market value; limitation; joinder; consolidation;
                 determination of issues; appointment of appraisers

         (a) If the corporation denies that the shares are dissenting shares, or
      the corporation and the shareholder fail to agree upon the fair market
      value of the shares, then the shareholder demanding purchase of such
      shares as dissenting shares or any interested corporation, within six
      months after the date on which notice of the approval by the outstanding
      shares (Section 152) or notice pursuant to subdivision (i) of Section 1110
      was mailed to the shareholder, but not thereafter, may file a complaint in
      the superior court of the proper county praying the court to determine
      whether the shares are dissenting shares or the fair market value of the
      dissenting shares or both or may intervene in any action pending on such a
      complaint.

         (b) Two or more dissenting shareholders may join as plaintiffs or be
      joined as defendants in any such action and two or more such actions may
      be consolidated.

         (c) On the trial of the action, the court shall determine the issues.
      If the status of the shares as dissenting shares is in issue, the court
      shall first determine that issue.  If the fair market value of the
      dissenting shares is in issue, the court shall determine, or shall appoint
      one or more impartial appraisers to determine, the fair market value of
      the shares.

      (S) 1305.  Report of appraisers; confirmation; determination by court;
                 judgment; payment; appeal; costs

         (a) If the court appoints an appraiser or appraisers, they shall
      proceed forthwith to determine the fair market value per share.  Within
      the time fixed by the court, the appraisers,

                                      C-3
<PAGE>
 
      or a majority of them, shall make and file a report in the office of the
      clerk of the court.  Thereupon, on the motion of any party, the report
      shall be submitted to the court and considered on such evidence as the
      court considers relevant.  If the court finds the report reasonable, the
      court may confirm it.

         (b) If a majority of the appraisers appointed fail to make and file a
      report within 10 days from the date of their appointment or within such
      further time as may be allowed by the court or the report is not confirmed
      by the court, the court shall determine the fair market value of the
      dissenting shares.

         (c) Subject to the provisions of Section 1306, judgment shall be
      rendered against the corporation for payment of an amount equal to the
      fair market value of each dissenting share multiplied by the number of
      dissenting shares which any dissenting shareholder who is a party, or who
      has intervened, is entitled to require the corporation to purchase, with
      interest thereon at the legal rate from the date on which judgment was
      entered.

         (d) Any such judgment shall be payable forthwith with respect to
      uncertificated securities and, with respect to certificated securities,
      only upon the endorsement and delivery to the corporation of the
      certificates for the shares described in the judgment.  Any party may
      appeal from the judgment.

         (e) The costs of the action, including reasonable compensation to the
      appraisers to be fixed by the court, shall be assessed or apportioned as
      the court considers equitable, but, if the appraisal exceeds the price
      offered by the corporation, the corporation shall pay the costs (including
      in the discretion of the court attorneys' fees, fees of expert witnesses
      and interest at the legal rate on judgments from the date of compliance
      with Sections 1300, 1301 and 1302 if the value awarded by the court for
      the shares is more than 125 percent of the price offered by the
      corporation under subdivision (a) of Section 1301).

      (S) 1306.  Prevention of immediate payment; status as creditors; interest

         To the extent that the provisions of Chapter 5 prevent the payment to
      any holders of dissenting shares of their fair market value, they shall
      become creditors of the corporation for the amount thereof together with
      interest at the legal rate on judgments until the date of payment, but
      subordinate to all other creditors in any liquidation proceeding, such
      debt to be payable when permissible under the provisions of Chapter 5.

      (S) 1307.  Dividends on dissenting shares

         Cash dividends declared and paid by the corporation upon the dissenting
      shares after the date of approval of the reorganization by the outstanding
      shares (Section 152) and prior to payment for the shares by the
      corporation shall be credited against the total amount to be paid by the
      corporation therefor.

                 of demand for payment

         Except as expressly limited in this chapter, holders of dissenting
      shares continue to have all the rights and privileges incident to their
      shares, until the fair market value of their shares is agreed upon or
      determined.  A dissenting shareholder may not withdraw a demand for
      payment unless the corporation consents thereto.

      (S) 1309.  Termination of dissenting share and shareholder status

         Dissenting shares lose their status as dissenting shares and the
      holders thereof cease to be dissenting shareholders and cease to be
      entitled to require the corporation to purchase their shares upon the
      happening of any of the following:

         (a) The corporation abandons the reorganization.  Upon abandonment of
      the reorganization, the corporation shall pay on demand to any dissenting
      shareholder who has initiated proceedings in good faith under this chapter
      all necessary expenses incurred in such proceedings and reasonable
      attorneys' fees.

         (b) The shares are transferred prior to their submission for
      endorsement in accordance with Section 1302 or are surrendered for
      conversion into shares of another class in accordance with the articles.

         (c) The dissenting shareholder and the corporation do not agree upon
      the status of the shares as dissenting shares or upon the purchase price
      of the shares, and neither files a complaint or intervenes in a pending
      action as provided in Section 1304, within six months after the date on
      which notice of the approval by the outstanding shares or notice pursuant
      to subdivision (i) of Section 1110 was mailed to the shareholder.

         (d) The dissenting shareholder, with the consent of the corporation,
      withdraws the shareholder's demand for purchase of the dissenting shares.

      (S) 1310.  Suspension of right to compensation or valuation proceedings;
                 litigation of shareholders' approval

         If litigation is instituted to test the sufficiency or regularity of
      the votes of the shareholders in authorizing a reorganization, any
      proceedings under Sections 1304 and 1305 shall be suspended until final
      determination of such litigation.

      (S) 1311.  Exempt shares

         This chapter, except Section 1312, does not apply to classes of shares
      whose terms and provisions specifically set forth the amount to be paid in
      respect to such shares in the event of a reorganization or merger.

      to demand payment of cash for the shares held by the shareholder shall
      have any right at law or in equity to attack the validity of the
      reorganization or short-form merger, or to have the reorganization or
      short-form merger set aside or rescinded, except in an action to test
      whether the number of shares required to authorize or approve the
      reorganization have been legally voted in favor thereof; but any holder of
      shares of a class whose terms and provisions specifically set forth the
      amount to be paid in respect to them in the event of a reorganization or
      short-form merger is entitled to payment in accordance with those terms
      and provisions or, if the principal terms of the reorganization are
      approved pursuant to subdivision (b) of Section 1202, is entitled to
      payment in accordance with the terms and provisions of the approved
      reorganization.

         (b) If one of the parties to a reorganization or short-form merger is
      directly or indirectly controlled by, or under common control with,
      another party to the reorganization or short-form merger, subdivision (a)
      shall not apply to any shareholder of such party who has not demanded
      payment of cash for such shareholder's shares pursuant to this chapter;
      but if the shareholder institutes any action to attack the validity of the
      reorganization or short-form merger or to have the reorganization or
      short-form merger set aside or rescinded, the shareholder shall not
      thereafter have any right to demand payment of cash for the shareholder's
      shares pursuant to this chapter.  The court in any action attacking the
      validity of the reorganization or short-form merger or to have the
      reorganization or short-form merger set aside or rescinded shall not
      restrain or enjoin the consummation of the transaction except upon 10
      days' prior notice to the corporation and upon a determination by the
      court that clearly no other remedy will adequately protect the complaining
      shareholder or the class of shareholders of which such shareholder is a
      member.

         (c) If one of the parties to a reorganization or short-form merger is
      directly or indirectly controlled by, or under common control with,
      another party to the reorganization or short-form merger, in any action to
      attack the validity of the reorganization or short-form merger or to have
      the reorganization or short-form merger set aside or rescinded, (1) a
      party to a reorganization or short-form merger which controls another
      party to the reorganization or short-form merger shall have the burden of
      proving that the transaction is just and reasonable as to the shareholders
      of the controlled party, and (2) a person who controls two or more parties
      to a reorganization shall have the burden of proving that the transaction
      is just and reasonable as to the shareholders of any party so controlled.

      Plan is to promote the interests of San Diego Gas & Electric Company and
      its shareholders by encouraging officers and key employees to acquire
      stock or increase their proprietary interest in the Company.  By thus
      providing the opportunity to acquire Company stock and receive incentive
      payments, the Company seeks to attract and retain such key employees upon
      whose judgment, initiative, and leadership the success of the Company
      largely depends.      
    
         This amended and restated Plan (a) permits the grant of incentive stock
      options as defined in section 422 of the Internal Revenue Code of 1986, as
      amended (the "Code"), as well as options that are not incentive stock
      options and other awards; (b) extends the term of the Plan; (c) adds
      provisions for the grant of Common Stock to non-employee directors; (d)
      adds an individual grant limitation required by section 162(m) of the Code
      for award income for certain individuals to be tax deductible by the
      Company; and (e) makes certain additional changes.      
    
         2.  Definitions.  Whenever the following terms are used in this Plan,

      be "disinterested" only if he or she satisfies such requirements as the
      Securities and Exchange Commission may establish for disinterested
      administrators acting under plans intended to qualify for exemption under
      Rule 16b-3 under the Securities Exchange Act of 1934 (or any other
      comparable provisions in effect at the time or times in question).  An
      Outside Director shall not fail to be "disinterested" solely because he or
      she receives the grants of Common Stock described in Section 6.  The Board
      may also appoint one or more separate committees of the Board, each
      composed of two or more directors  of the Company who need not be
      disinterested, who may administer the Plan with respect to Employees who
      are not  officers or directors of the Company, may grant Incentive Awards
      under the Plan to such Employees and may determine all terms of such
      Awards.  Unless and until the Board of Directors appoints other members,
      and subject to the requirement that they be "disinterested," the members
      of the Committee shall be the members of the Executive Compensation
      Committee of the Board of Directors, as such Executive Compensation
      Committee may be constituted from time to time.      
    
         (b)  The Committee has and may exercise such powers and authority as
      may be necessary or appropriate for the Committee to carry out its
      functions as described in the Plan.  The Committee has authority in its
      discretion to determine the Eligible Persons to whom, and the time or
      times at which, Incentive Awards may be granted and the number of shares
      or Rights subject to each award. Subject to the express provisions of the
      Plan, the Committee also has authority to interpret the Plan, and to
      determine the terms and provisions of the respective Incentive Award
      agreements (which need not be identical) and to make all other
      determinations necessary or advisable for Plan administration.  The
      Committee has authority to prescribe, amend, and rescind rules and
      regulations relating to the Plan.  All interpretations, determinations,
      and actions by the Committee will be final, conclusive, and binding upon
      all parties.      
    
         (c)  No member of the Board of Directors or the Committee will be
      liable for any action or determination made in good faith by the Committee
      with respect to the Plan or any Incentive and Performance Award under it.
         
         5.  Eligibility and Date of Grant.      
             -----------------------------

      and designate from time to time those Eligible Persons who are to be
      granted Incentive Awards, the type of Incentive Awards to be granted, and
      the number of Rights, shares of Common Stock, or the      

                                      D-4
<PAGE>
 
    
      amount of cash subject to each Incentive Award.  Each Incentive Award will
      be evidenced by a written instrument and may include any other terms and
      conditions consistent with the Plan, as the Committee may determine.      
    
         (b)  The date of grant of an Incentive Award will be the date the
      Committee takes the necessary action to approve the grant; provided,
      however, that if the minutes or appropriate resolutions of the Committee
      provide that an Incentive Award is to be granted as of a date in the
      future, the date of grant will be such future date.      
    
         (c)  Any other provision of the Plan notwithstanding, the participation
      of Outside Directors in the Plan shall be limited such that Outside
      Directors shall receive no Incentive Awards other than the Common Stock
      granted pursuant to Section 6 hereof.     
    
         6.  Outside Director Participation.  Upon the conclusion of each
             ------------------------------                              
      regular annual meeting of the Company's shareholders, each incumbent
      Outside Director who will continue serving as a member of the Board
      thereafter shall receive a grant of 300 Common Shares (subject to
      adjustment under Section 15 and prorated for partial year service) in
      consideration of past service as a member of the Board and without
      additional payment for such Common Shares.      
    
         7.  Nonqualified Stock Options.      
             -------------------------- 
    
      The Committee may approve the grant of Nonqualified Stock Options to
      Eligible Persons, subject to the following terms and conditions:      
    
         (a)  The purchase price of Common Stock under each Nonqualified Stock
      Option may not be less than one hundred percent (100%) of the Fair Market
      Value of the Common Stock on the date the Nonqualified Stock Option is
      granted.      
    
         (b)  No Nonqualified Stock Option may be exercised after ten (10) years
      and one day from the date of grant.      
    
         (c)  No fractional shares will be issued pursuant to the exercise of a
      Nonqualified Stock Option nor will any cash payment be made in lieu of
      fractional shares.      
    
         8.  Incentive Stock Options.  The Committee may approve the grant of
             -----------------------                                         
      Incentive Stock Options to Eligible Persons, subject to the following
      terms and conditions:      
    
         (a)  The purchase price of each share of Common Stock under an
      Incentive Stock Option will be at least equal to the Fair Market Value of
      a share of the Common Stock on the date of grant; provided, however, that
      if an Employee, at the time an Incentive Stock Option is granted, owns
      stock representing more than ten percent (10%) of the total combined
      voting power of all classes of stock of the Company (as defined in section
      424 of the Code), then the Exercise Price of each share of Common Stock
      subject to such Incentive Stock Option shall be at least one hundred and
      ten percent (110%) of the Fair Market Value of such share of Common Stock,
      as determined in the manner stated above.      

                                      D-5
<PAGE>
 
    
         (b)  No Incentive Stock Option may be exercised after ten (10) years
      from the date of grant; provided, however, that if any Employee, at the
      time an Incentive Stock Option is granted to him, owns stock representing
      more than ten percent (10%) of the total combined voting power of all
      classes of stock of the Company (as defined in Section 424 of the Code),
      the Incentive Stock Option granted shall not be exercisable after the
      expiration of five (5) years from the date of grant.      
    
         (c)  No fractional shares will be issued pursuant to the exercise of an
      Incentive Stock Option nor will any cash payment be made in lieu of

      to Section 11 hereof during the period, shall in no event cover more than

      be paid in cash, cash equivalents or secured notes acceptable to the
      Committee, by arrangement with a broker which is acceptable to the
      Committee where payment of the option price is made pursuant to an
      irrevocable direction to the broker to deliver all or part of the proceeds
      from the sale of the Option shares to the Company, by the surrender of
      shares of Common Stock owned by the Holder exercising the option and
      having a Fair Market Value on the date of exercise equal to the purchase
      price or in any combination of the foregoing.  Each Option granted to an
      Eligible Person shall be exercisable in such manner and at such times as
      the Committee shall determine.  The Committee may modify, accelerate the
      exercisability of, extend or assume outstanding Options or may accept the
      cancellation of outstanding options (whether granted by the Company or by
      another issuer) in return for the grant of new Options for the same or a
      different number of shares and at the same or a different purchase price.
      The foregoing notwithstanding, no modification of an Option shall, without
      the consent of the Holder, alter or impair his or her rights or
      obligations under such Option.      
    
         10.  Restricted Stock.  The Committee may approve the grant of
              ----------------

         (b)  All shares of Restricted Stock sold or granted pursuant to the
      Plan (including any shares of Restricted Stock received by the Holder as a

      capitalization) will be subject to the following restrictions:      
    
          (i)    The shares may not be sold, transferred, or otherwise alienated
        or hypothecated until the restrictions are removed or expire.      
    
          (ii)   The Committee may require the Holder to enter into an escrow
        agreement providing that the certificates representing Restricted Stock
        sold or      
    
         granted pursuant to the Plan will remain in the physical custody of an
         escrow holder until all restrictions are removed or expire.

          (iii)  Each certificate representing Restricted Stock sold or granted

        the restrictions imposed on the Restricted Stock.      
    
          (iv)   The Committee may impose restrictions on any shares sold
        pursuant to the Plan as it may deem advisable, including, without
        limitation, restrictions designed to facilitate exemption from or
        compliance with the Securities Exchange Act of 1934, as amended, with
        requirements of any stock exchange upon which such shares or shares of
        the same class are then listed and with any blue sky or other securities
        laws applicable to such shares.      
    
         (c)  The restrictions imposed under subparagraph (b) above upon
      Restricted Stock will lapse in accordance with a schedule or other
      conditions as determined by the Committee, subject to the provisions of
      Section 17, subparagraph (d).      
    
         (d)  Subject to the provisions of subparagraph (b) above and Section
      17, subparagraph (d), the holder will have all rights of a shareholder
      with respect to the Restricted Stock granted or sold, including the right
      to vote the shares and receive all dividends and other distributions paid
      or made with respect thereto.      
    
         11.  Stock Appreciation Rights.  The Committee may approve the grant of
              -------------------------                                         
      Rights related or unrelated to Options to Eligible Persons, subject to the
      following terms and conditions:      
    
         (a)  A Stock Appreciation Right may be granted:      
    
          (i)    at any time if unrelated to an option;      
    
          (ii)   either at the time of grant, or at any time thereafter during
        the option term if related to a Nonqualified Stock Option;      
    
          (iii)  only at the time of grant if related to an Incentive Stock
        Option;      
    
          (iv)   Stock Appreciation Rights granted to any Eligible Person prior
        to April 24, 2005, together with Options granted pursuant to Sections 7
        or 8 hereof during the period, shall in no event cover more than 270,000
        shares of Common Stock.      
    
         (b)  A Stock Appreciation Right granted in connection with an Option
      will entitle the Holder of the related Option, upon exercise of the Stock
      Appreciation Right, to surrender such Option, or any portion thereof to
      the extent unexercised, with respect to the number of shares as to which
      such Stock Appreciation Right is exercised, and to receive payment of an
      amount computed pursuant to Section 11(d).  Such Option will, to the
      extent surrendered, then cease to be exercisable.      
    
         (c)  Subject to Section 11(g), a Stock Appreciation Right granted in
      connection with an Option hereunder will be exercisable at such time or
      times, and only to the extent that a related Option is exercisable, and
      will not be transferable except to the extent that such related Option
     

                                      D-7
<PAGE>
 
    
      is exercisable, and will not be transferable except to the extent that
      such related Option may be transferable.      
    
         (d)  Upon the exercise of a Stock Appreciation Right related to an
      Option, the Holder will be entitled to receive payment of an amount
      determined by multiplying:      
    
          (i)   The difference obtained by subtracting the purchase price of a
        share of Common Stock specified in the related Option from the Fair
        Market Value of a share of Common Stock on the date of exercise of such
        Stock Appreciation Right, by      
    
          (ii)  The number of shares as to which such Stock Appreciation Right
        has been exercised.      
    
         (e)  The Committee may grant Stock Appreciation Rights unrelated to
      Options to Eligible Persons which will be exercisable at such times as the
      Committee shall determine.  Section 11(d) shall be used to determine the
      amount payable at exercise under such Stock Appreciation Right if Fair
      Market Value is used, except that Fair Market Value shall not be used if
      the Committee specified in the grant of the Right that book value or other
      measure as deemed appropriate by the Committee was to be used, and in lieu
      of "price . . . specified in the related option," the initial share value
      specified in the award shall be used.      
    
         (f)  Payment of the amount determined under Section 11(d) or (e) may be
      made solely in whole shares of Common Stock in a number determined at
      their Fair Market Value on the date of exercise of the Stock Appreciation
      Right or alternatively, at the sole discretion of the Committee, solely in
      cash or in a combination of cash and shares as the Committee deems
      advisable.  If the Committee decides to make full payment in shares of
      Common Stock, and the amount payable results in a fractional share,
      payment for the fractional share will be made in cash.      
    
         (g)  The Committee  shall, at the time a Stock Appreciation Right is
      granted, impose such conditions on the exercise of the Stock Appreciation
      Right as may be required to satisfy the requirements of Rule 16b-3 under
      the Securities Exchange Act of 1934 (or any other comparable provisions in
      effect at the time or times in question).  In addition, a Stock
      Appreciation Right granted under the Plan may provide that it will be
      exercisable only in the event of a Change-in-Control.      
    
         12.  Performance Awards.  The Committee may approve Performance Awards
              ------------------                                               
      to Eligible Persons.  Such awards may be based on Common Stock performance
      over a period determined in advance by the Committee or any other measures
      as determined appropriate by the Committee.  Payment will be in cash
      unless replaced by a Stock Payment in full or in part as determined by the
      Committee.      
    
         13.  Stock Payment.  The Committee may approve Stock Payments of Common
              -------------                                                     
      Stock to Eligible Persons for all or any portion of the compensation
      (other than base salary) that would otherwise become payable to an
      Employee in cash.      

                                      D-8
<PAGE>
 
    
         14.  Dividend Equivalents.  A Holder may also be granted at no
              --------------------                                     
      additional cost "Dividend Equivalents" based on the dividends declared on
      the Common Stock on record dates during the period between the date an
      Option is granted and the date such Option is exercised, or such other
      equivalent period, as determined by the Committee.  Such Dividend
      Equivalents shall be converted to additional shares or cash by such
      formula as may be determined by the Committee.      
    
         Dividend Equivalents shall be computed, as of each dividend record
      date, both with respect to the number of shares under the Option and with
      respect to the number of Dividend Equivalent shares previously earned by
      the Holder (or his successor in interest) and not issued during the period
      prior to the dividend record date.      
    
         15.  Adjustment Provisions.      
              --------------------- 
    
         (a)  Subject to Section 15(b), if the outstanding shares of Common
      Stock are increased, decreased, or exchanged for a different number or
      kind of shares or other securities, or if additional shares or new or
      different shares or other securities are distributed with respect to such
      shares of Common Stock or other securities, through merger, consolidation,
      sale of all or substantially all of the property of the Company,
      reorganization, recapitalization, reclassification, stock dividend, stock
      split, reverse stock split or other distribution with respect to such
      shares of Common Stock, or other securities, an appropriate and
      proportionate adjustment may be made in (i) the maximum number and kind of
      shares provided in Section 3 of the Plan, (ii) the number and kind of
      shares or other securities subject to the then outstanding Incentive
      Awards, and (iii) the price for each share or other unit of any other
      securities subject to then outstanding Incentive Awards without change in
      the aggregate purchase price or value as to which Incentive Awards remain
      exercisable or subject to restrictions.      
    
         (b)  Unless a successor corporation, or its parent or a subsidiary,
      agrees to substitute new options, stock appreciation rights, performance
      awards or restricted stock covered by its stock, with appropriate
      adjustments as to the number and kind of shares and price, for all
      Incentive Awards then outstanding and to continue the Plan, all Incentive
      Awards then outstanding under the Plan shall be fully vested and
      exercisable without restrictions upon a Change-in-Control.  Even if the
      substitution of new awards and the continuation of the Plan are provided
      for upon a Change-in-Control, as described in the preceding sentence, all
      Incentive Awards then outstanding under the Plan shall immediately become
      fully vested and exercisable without restrictions by any Holder who within
      three years after a Change-in-Control occurs is terminated for reasons
      other than cause, retirement, death, or disability or who terminates
      employment due to Good Reason.      
    
         (c)  Despite the provisions of Section 15(a), upon dissolution or
      liquidation of the Company, or upon a reorganization, merger, or
      consolidation of the Company with one or more corporations as a result of
      which the Company is not the surviving corporation, or upon the sale of
      all or substantially all the property of the Company, all Options, Stock
      Appreciation Rights, and Performance Awards then outstanding under the
      Plan will be fully vested and exercisable and all restrictions on
      Restricted Stock will immediately cease, unless provisions are made in
      connection with such transaction for the continuance of the Plan and the
      substitution for such Incentive Awards of new Options, Stock Appreciation
      Rights, Performance Awards, or      

                                      D-9
<PAGE>
 
    
      Restricted Stock covering the stock of a successor employer corporation,
      or a parent or subsidiary thereof, with appropriate adjustments as to the
      number and kind of shares and prices.      
    
         (d)  Adjustments under Section 15(a) and 15(b) will be made by the
      Committee, whose determination as to what adjustments will made and the
      extent thereof will be final, binding, and conclusive.  No fractional
      interest will be issued under the Plan on account of any such adjustments.
         
         16.  General Provisions.      
              ------------------ 
    
         (a)  With respect to any shares of Common Stock issued or transferred
      under any provision of the Plan, such shares may be issued or transferred
      subject to such conditions, in addition to those specifically provided in
      the Plan, as the Committee may direct.      
    
         (b)  Nothing in the Plan or in any instrument executed pursuant to the
      Plan will confer upon any Holder any right to continue in the employ of
      the Company or any of its subsidiaries or affect the right of the Company
      to terminate the employment of any Holder at any time and for any reason.
         
         (c)  No shares of Common Stock will be issued or transferred pursuant
      to an Incentive Award unless and until all then applicable requirements
      imposed by federal and state securities and other laws, rules, and
      regulations and by any regulatory agencies having jurisdiction, and by any
      stock exchanges upon which the Common Stock may be listed, have been fully
      met.  As a condition precedent to the issue of shares pursuant to the
      grant or exercise of an Incentive Award, the Company may require the
      Holder to take any reasonable action to meet such requirements.      
    
         (d)  No Holder (individually or as a member of a group) and no
      beneficiary or other person claiming under or through such Holder will
      have any right, title, or interest in or to any shares of Common Stock
      allocated or reserved under the Plan or subject to any Incentive Award
      except as to such shares of Common Stock, if any, that have been issued or
      transferred to such Holder.      
    
         (e)  The Company may make such provisions as it deems appropriate to
      withhold any taxes which it determines it is required to withhold in
      connection with any Incentive or Performance Award.      
    
         (f)  No Incentive Award and no right under the Plan, contingent or
      otherwise, will be assignable or subject to any encumbrance, pledge (other
      than a pledge to secure a loan from the Company), or charge of any nature
      except that, under such rules and regulations as the Company may establish
      pursuant to the terms of the Plan, a beneficiary may be designated with
      respect to an Incentive Award in the event of death of a Holder of such
      Incentive Award.  If such beneficiary is the executor or administrator of
      the estate of the Holder of such Incentive Award, any rights with respect
      to such Incentive Award may be transferred to the person or persons or
      entity (including a trust) entitled thereto under the will of the Holder
      of such Incentive Award, or, in the case of intestacy, under the laws
      relating to intestacy.  Except as      

                                      D-10
<PAGE>
 
    
      permitted by the Committee, no Incentive Award which is comprised of a
      "derivative security," as that term is defined in the Rules promulgated
      under Section 16 of the Exchange Act, which includes Incentive Stock
      Options, Nonqualified Stock Options, Stock Appreciation Rights, or
      Performance Awards, shall be transferable by any Eligible Person other
      than by will or the laws of descent and distribution or pursuant to a
      qualified domestic relations order.      
    
         (g)   The Committee may permit a Holder to satisfy all or part of his
      or her withholding or income tax obligations by having the Company
      withhold all or a portion of any Common Stock that otherwise would be
      issued to him or her or by surrendering all or a portion of any Common
      Stock that he or she previously acquired.  Such Common Stock shall be
      valued at its Fair Market Value on the date when taxes otherwise would be
      withheld in cash.  Any payment of taxes by assigning Common Stock to the
      Company may be subject to restrictions, including any restrictions
      required by rules of the Securities and Exchange Commission.      
    
         17.  Amendment and Termination.      
              ------------------------- 
    
         (a)  The Board of Directors will have the power, in its discretion, to
      amend, suspend, or terminate the Plan at any time, except that the
      provisions of Section 6 relating to Common Stock grants to Outside
      Directors shall not be amended more than once in any six-month period
      after the Plan becomes effective.  An amendment of the Plan shall be
      subject to the approval of the Company's shareholders only to the extent
      required by applicable laws, regulations and or rules.      
    
         (b)  The Committee may, with the consent of a Holder, make such
      modifications in the terms and conditions of the Incentive Award as it
      deems advisable or cancel the Incentive Award (with or without
      consideration) with the consent of the  Holder.      
    
         (c)  No amendment, suspension, or termination of the Plan will, without
      the consent of the Holder, alter, terminate, impair, or adversely affect
      any right or obligation under any Incentive Award previously granted under
      the Plan.      
    
         (d)  In the event a Holder of Restricted Stock ceases to be an
      Employee, all such Holder's Restricted Stock which remains subject to
      substantial risk of forfeiture at the time his or her employment
      terminates will be repurchased by the Company at the original price at
      which such Restricted Stock had been purchased unless the Committee
      determines otherwise.      
    
         (e)  In the event a Holder of a Performance Award ceases to be an
      Employee, all such Holder's Performance Awards will terminate except in
      the case of retirement, death, or permanent and total disability.  The
      Committee, in its discretion, may authorize full or partial payment of
      Performance Awards in all cases involving retirement, death, or permanent
      and total disability.      
    
         (f)  The Committee may in its sole discretion determine, with respect
      to an Incentive Award, that any Holder who is on unpaid leave of absence
      for any reason will be considered as still in the employ of the Company,
      provided that rights to such Incentive Award during an      

                                      D-11
<PAGE>
 
    
      unpaid leave of absence will be limited to the extent to which such right
      was earned or vested at the commencement of such leave of absence.      
    
         18.  Effective Date of Plan and Duration of Plan.  This  amended and
              -------------------------------------------                    
      restated Plan will become effective upon approval by the shareholders of
      the Company within twelve (12) months following the date of its adoption
      by the Board of Directors.  Unless previously terminated by the Board of
      Directors, the Plan will terminate ten (10) years after its approval by
      the shareholders of the Company.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


      Item 20.  Indemnification of Directors and Officers.
    
         Pursuant to the California Corporations Code, Article EIGHTH of the
      Registrant's Articles of Incorporation and provisions of the Registrant's
      Bylaws, directors, officers, employees and agents of the Registrant may be
      indemnified by the Registrant in certain circumstances against liabilities
      they incur while acting in such capacities.  Upon the effectiveness of the
      Merger (as contemplated in Part I of this Registration Statement), the
      Registrant will have directors' and officers' liability insurance policies
      in force insuring directors and officers of the Registrant and its
      subsidiaries.      

      Item 21.  Exhibits and Financial Statement Schedules.

         See Exhibit Index.

      Item 22.  Undertakings.

         The undersigned Registrant hereby undertakes:

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

               (i)     To include any prospectus required by Section 10(a)(3) of
      the Securities Act of 1933;

               (ii)    To reflect in the prospectus any facts or events arising
      after the effective date of the Registration Statement (or the most recent
      post-effective amendment thereof) which, individually or in the aggregate,
      represent a fundamental change in the information set forth in the
      Registration Statement;

               (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;

           (2) That, for the purpose of determining any liability under the
      Securities Act of 1933, 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 a post-effective
      amendment any of the securities being registered which remain unsold at
      the termination of the offering.

         The undersigned registrant hereby undertakes that, for purposes of
      determining any liability under the Securities Act of 1933, each filing of
      an annual report of the Registrant or San Diego Gas & Electric Company
      pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
      of 1934 that is incorporated by reference in the Registration Statement
      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.

         The undersigned Registrant hereby undertakes as follows:

           (1) That prior to any public reoffering of the securities registered
      hereunder through use of a prospectus which is a part of this Registration
      Statement, by any person or party who is deemed to be an underwriter
      within the meaning of Rule 145(c), the issuer undertakes that such
      reoffering prospectus will contain the information called for by the
      applicable registration form with respect to reofferings by persons who
      may be deemed underwriters, in addition to the information called for by
      the other items of the applicable form.

                                      II-1
<PAGE>
 
           (2) That every prospectus (i) that is filed pursuant to paragraph (1)
      immediately preceding, or (ii) that purports to meet the requirements of
      Section 10(a)(3) of the Securities Act of 1933 and is used in connection
      with an offering of securities subject to Rule 415, will be filed as a
      part of an amendment to the Registration Statement and will not be used
      until such amendment is effective, and that, for purposes of determining
      any liability under the Securities Act of 1933, 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.

         Insofar as indemnification for liabilities arising under the Securities
      Act of 1933 may be permitted to directors, officers and controlling
      persons of the registrant pursuant to the provisions described in Item 20
      above, or otherwise, the registrant has been advised that in the opinion
      of the Securities and Exchange Commission such indemnification is against
      public policy as expressed in the Securities Act of 1933 and is,
      therefore, unenforceable.  In the event that a claim for indemnification
      against such liabilities (other than the payment by the registrant of
      expenses incurred or paid by a director, officer or controlling person of
      the registrant in the successful defense of any action, suit or
      proceeding) is asserted by such director, officer or controlling person in
      connection with the securities being registered, the registrant will,
      unless in the opinion of its counsel the matter has been settled by
      controlling precedent, submit to a court of appropriate jurisdiction the
      question whether such indemnification by it is against public policy as
      expressed in the Securities Act of 1933 and will be governed by the final
      adjudication of such issue.

         The undersigned registrant hereby undertakes to respond to requests for
      information that is incorporated by reference into the Proxy Statement and
      Prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one
      business day of receipt of such request, and to send the incorporated
      documents by first class mail or other equally prompt means.  This
      includes information contained in documents filed subsequent to the
      effective date of the Registration Statement through the date of
      responding to the request.

         The undersigned registrant hereby undertakes to supply by means of a
      post-effective amendment all information concerning a transaction, and the
      company being acquired involved therein, that was not the subject of and
      included in the Registration Statement when it became effective.

                                 -------------
                  Indemnification of Agents of the Corporation
                  --------------------------------------------


      Section 1.  Definitions.  For the purposes of this Article Seven,
                  -----------                                          
"agent" means any person who (i) is or was a Director, officer, employee or
other agent of the Corporation, (ii) is or was serving at the request of the
Corporation as a director, officer, employee or agent of another foreign or
domestic corporation, partnership, joint venture, trust or other enterprise or
(iii) was a director, officer, employee or agent of a foreign or domestic
corporation which was a predecessor corporation of the Corporation or of another
enterprise at the request of such predecessor corporation; "proceeding" means
any threatened, pending or completed action or proceeding, whether civil,
criminal, administrative or investigative; and "expenses" includes, without
limitation, attorneys' fees and any expenses of establishing a right to
indemnification under Sections 4 or 5(c) of this Article Seven.

      Section 2.  Indemnification for Third Party Actions.  The Corporation
                  ---------------------------------------                  
shall have the power to indemnify any person who is or was a party, or is
threatened to be made a party, to any proceeding (other than an action by or in
the right of the Corporation to procure a judgment in its favor) by reason of
the fact that such person is or was an agent of the Corporation against
expenses, judgments, fines, settlements and other amounts actually and
reasonably incurred in connection with such proceeding if such person acted in
good faith and in a manner such person reasonably believed to be in the best
interests of the Corporation and, in the case of a criminal proceeding, had no
reasonable cause to believe the conduct of such person was unlawful.  The
termination of any proceeding by judgment, order, settlement, conviction or upon
a plea of nolo contendere or its equivalent shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which the
person reasonably believed to be in the best interests of the Corporation or
that the person had reasonable cause to believe that the person's conduct was
unlawful.

      Section 3.  Indemnification for Derivative Actions.  The Corporation
                  --------------------------------------

threatened to be made a party, to any

<PAGE>
 
threatened, pending or completed action by or in the right of the Corporation to
procure a judgment in its favor by reason of the fact that such person is or was
an agent of the Corporation against expenses actually and reasonably incurred by
such person in connection with the defense or settlement of such action if such
person acted in good faith and in a manner such person believed to be in the
best interests of the Corporation and its Shareholders.  No indemnification
shall be made under this Section 3:

          (a)     In respect of any claim, issue or matter as to which such
                  person shall have been adjudged to be liable to the
                  Corporation in the performance of such person's duty to the
                  Corporation and its Shareholders, unless and only to the
                  extent that the court in which such proceeding is or was
                  pending shall determine upon application that, in view of all
                  the circumstances of the case, such person is fairly and
                  reasonably entitled to indemnity for expenses and then only to
                  the extent that the court shall determine; or

          (b)     Of amounts paid in settling or otherwise disposing of a
                  pending action without court approval; or

          (c)     Of expenses incurred in defending a pending action which is
                  settled or otherwise disposed of without court approval.

      Section 4.  Successful Defense.  Notwithstanding any other provision
                  ------------------                                      
of this Article, to the extent that an agent of the Corporation has been
successful on the merits or otherwise (including the dismissal of an action
without prejudice or the settlement of a proceeding or action without admission
of liability) in defense of any proceeding referred to in Sections 2 or 3 of
this Article, or in defense of any claim, issue or matter therein, he or she
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred in connection therewith.

      Section 5.  Discretionary Indemnification.  Except as provided in
                  -----------------------------                        
Section 4 of this Article Seven, any indemnification under Section 3 hereof
shall be made by the Corporation only if authorized in the specific case, upon a
determination that indemnification of the agent is proper in the circumstances
because the agent has met the applicable standard of conduct set forth in
Section 3, by:

          (a)     A majority vote of a quorum consisting of Directors who are
                  not parties to such proceeding;

          (b)     If such a quorum of Directors is not obtainable, by
                  independent legal counsel in a written opinion;

          (c)     Approval by the affirmative vote of a majority of the shares
                  of this Corporation represented and voting at a duly held
                  meeting at which a quorum is present (which shares voting
                  affirmatively also constitute at least a majority of the
                  required quorum) or by the written consent of holders of a
                  majority of the outstanding shares which would be entitled to
                  vote at

                                      -8-
<PAGE>
 
                  such meeting and, for such purpose, the shares owned by the
                  person to be indemnified shall not be considered outstanding
                  or entitled to vote; or

          (d)     The court in which such proceeding is or was pending, upon
                  application made by the Corporation, the agent or the attorney
                  or other person rendering services in connection with the
                  defense, whether or not such application by said agent,
                  attorney or other person is opposed by the Corporation.

      Section 6.  Advancement of Expenses.  Expenses incurred in defending
                  -----------------------                                 
any proceeding may be advanced by the Corporation prior to the final disposition
of such proceeding upon receipt of an undertaking by or on behalf of the agent
to repay such amount if it shall be determined ultimately that the agent is not
entitled to be indemnified as authorized in this Article Seven.

      Section 7.  Restriction on Indemnification.  No indemnification or
                  ------------------------------                        
advance shall be made under this Article Seven, except as provided in Sections 4
and 6 hereof, in any circumstance where it appears:

          (a)     That it would be inconsistent with a provision of the Articles
                  of Incorporation of the Corporation, its bylaws, a resolution
                  of the Shareholders or an agreement in effect at the time of
                  the accrual of the alleged cause of action asserted in the
                  proceeding in which the expenses were incurred or other
                  amounts were paid which prohibits or otherwise limits
                  indemnification; or

          (b)     That it would be inconsistent with any condition expressly
                  imposed by a court in approving a settlement.

      Section 8.  Non-Exclusive.  In the absence of any other basis for
                  -------------                                        
indemnification of an agent, the Corporation can indemnify such agent pursuant
to this Article Seven.  The indemnification provided by this Article Seven shall
not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled under any statute, bylaw, agreement, vote of
Shareholders or disinterested Directors or otherwise, both as to action in an
official capacity and as to action in another capacity while holding such
office.  The rights to indemnification under this Article Seven shall continue
as to a person who has ceased to be a Director, officer, employee, or agent and
shall inure to the benefit of the heirs, executors, and administrators of the
person.  Nothing contained in this Section 8 shall affect any right to
indemnification to which persons other than such Directors and officers may be
entitled by contract or otherwise.

      Section 9.  Expenses as a Witness.  To the extent that any agent of
                  ---------------------                                  
the Corporation is by reason of such position, or a position with another entity
at the request of the Corporation, a witness in any action, suit or proceeding,
he or she shall be indemnified against all costs and expenses actually and
reasonably incurred by him or her or on his or her behalf in connection
therewith.

      Section 10. Insurance.  The Board may purchase and maintain
                  ---------                                      
directors and officers liability insurance, at its expense, to protect itself
and any Director, officer or other named or specified agent of the Corporation
or another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss asserted against or incurred by the agent
in such capacity or arising out of the agent's status as such, whether or not
the Corporation would have the power to indemnify the agent against such
expense, liability or loss under the provisions of this Article Seven or under
California Law.

      Section 11. Separability.  Each and every paragraph, sentence, term
                  ------------                                           
and provision of this Article Seven is separate and distinct so that if any
paragraph, sentence, term or provision hereof shall be held to be invalid or
unenforceable for any reason, such invalidity or unenforceability shall not
affect the validity or unenforceability of any other paragraph, sentence, term
or provision hereof.  To the extent required, any paragraph, sentence, term or
provision of this Article may be modified by a court of competent jurisdiction
to preserve its validity and to provide the claimant with, subject to the
limitations set forth in this Article and any agreement between the Corporation
and claimant, the broadest possible indemnification permitted under applicable
law.  If this Article Seven or any portion hereof shall be invalidated on any
ground by any court of competent jurisdiction, then the Corporation shall
nevertheless have the power to indemnify each Director, officer, employee, or
other agent against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement with respect to any action, suit, proceeding or

           Re:  Issuance of Common Stock in Connection with Formation of a
                Holding Company Structure for SDG&E


      Ladies and Gentlemen:

           With reference to the Registration Statement on Form S-4 (No. 33-

      respect to the issuance of up to 116,541,000 shares of ParentCo's common
      stock in connection with a merger which will cause ParentCo to become the

                               February 17, 1995



      San Diego Gas & Electric Company
      101 Ash Street
      San Diego, CA 92101


      Ladies and Gentlemen:

           You have asked for our opinion as to certain federal income tax
      consequences of a proposed transaction that would result in the creation
      of a holding company structure for San Diego Gas & Electric Company
      ("SDG&E") and its subsidiaries.  The proposed transaction is set forth in
      the Agreement of Merger (the "Agreement") among SDG&E, SDO Parent Co.
      ("ParentCo") and San Diego Merger Company ("MergeCo") set forth as Exhibit
      A to the Proxy Statement/Prospectus of ParentCo included in ParentCo's
      Registration Statement on Form S-4 filed with the Securities and Exchange
      Commission on December 22, 1994 (the "Registration Statement").  We
      understand, and the opinions rendered herein assume, that the facts
      surrounding the proposed transaction are as follows.

           SDG&E, a California corporation, is engaged in the sale of natural
      gas and electricity.  SDG&E has authorized capital of: (i) 255 million
      shares of no par value common stock ("Common Stock"); (ii) 1.375 million
      shares of $20 par value cumulative voting preferred stock ("Preferred
      Stock"); and (iii) 10 million shares of no par value cumulative nonvoting
      preference stock ("Preference Stock").  As of September 30, 1994, SDG&E
      had the following outstanding shares of stock: (i) 116,475,955 shares of
      Common Stock; (ii) four different series of Preferred Stock aggregating
      1,374,650 shares; and (iii) four different series of Preference Stock
      aggregating 3,190,000 shares.  The SDG&E Common Stock is widely held and
      publicly traded on the New York and Pacific Stock Exchanges.  The SDG&E
      Preferred and Preference series are publicly traded on the American and
      Pacific Stock Exchanges, except for the 4.6% Series of SDG&E Preferred
      Stock and the $1.70 and $1.7625 Series of SDG&E Preference Stock, which
      are traded over the counter.

           Califia Company ("Califia"), a California corporation, is engaged in
      the business of leasing computer equipment.  Califia has outstanding
      27,249 shares of no par value voting common stock, 25,000 shares of Series
      A $9.25 no par value nonvoting preferred stock and
<PAGE>
 
      San Diego Gas & Electric Company
      February 17, 1995
      Page 2


      36,500 shares of Series B $8.75 no par value nonvoting preferred stock.
      SDG&E owns all of the outstanding common stock, 21,350 shares (85.4%) of
      the Series A preferred stock and 31,000 shares (84.9%) of the Series B
      preferred stock.  The remaining outstanding preferred stock is held by CMA
      Leasing Associates, an unrelated entity.

           Enova Corporation ("Enova"), a California corporation, is a wholly
      owned subsidiary of SDG&E which invests in affordable housing projects
      through multiple limited partnership interests.

           Pacific Diversified Capital Company ("PDCC"), a California
      corporation, is a wholly owned subsidiary of SDG&E which acts as a holding
      company.  PDCC owns all of the stock of Phase One Development, Inc.
      ("Phase One") and 81 percent of the stock of Wahlco Environmental Systems,
      Inc. ("WESI").  The remaining 19 percent of the stock of WESI is publicly
      owned.

           Phase One is a California corporation engaged in the business of real
      estate development.

           WESI, a Delaware corporation, is a holding company which owns Wahlco,
      Inc. and several other subsidiaries engaged in the air pollution control
      business.

           Enova Energy Management, Inc. ("EEMI"), a California corporation, is
      a wholly owned subsidiary of SDG&E engaged in the business of energy
      procurement consulting services.

           ParentCo, a California corporation, was formed for the purpose of
      engaging in business as a holding company.  ParentCo has authorized
      capital consisting of 300 million shares of common stock and 30 million
      shares of preferred stock, none of which have been issued.

           MergeCo, a California corporation, was formed solely for the purpose
      of consummating the proposed transaction.  MergeCo has authorized capital
      consisting of 1000 shares of common stock, none of which have been issued.

           The management of SDG&E has determined that the proposed transaction
      would be in the best interests of SDG&E, Califia, Enova, PDCC, EEMI and
      the SDG&E stockholders.  The management of SDG&E believes that a holding
      company structure would facilitate the acquisition and integration of
      other energy related operations by providing a more clearly defined
      separation of utility and non-utility operations and would permit the use
      of financing techniques that are more directly suited to the particular
      requirements, characteristics and risks of non-utility operations with
      substantially less impact on the capital structure or credit of SDG&E,
      thereby increasing and improving SDG&E's financial flexibility.

           Accordingly, the following steps have occurred:

           Step 1  On December 20, 1994, ParentCo was incorporated; and

           Step 2  On January 6, 1995, MergeCo was incorporated.

           Following the receipt of certain regulatory approvals, the following
      steps will occur:

           Step 3  100 shares of common stock of ParentCo will be issued to
                SDG&E; and

           Step 4  100 shares of common stock of MergeCo will be issued to
                ParentCo.

           Pursuant to authority conferred on December 19, 1994 by the board of
      directors of SDG&E and anticipated to be conferred on February 27, 1995 by
      the board of directors of ParentCo and on April 25, 1995 by the
      shareholders of SDG&E, and upon satisfaction of certain regulatory
      conditions, the following steps will occur in the following sequence:

           Step 5  MergeCo will merge with and into SDG&E according to
                applicable state law; and

           Step 6  SDG&E will distribute all of its stock of Califia, Enova,
                PDCC and EEMI to ParentCo.

           Under the merger described in Step 5, SDG&E will be the surviving
      corporation and each outstanding share of SDG&E common stock will be
      automatically converted into one share of common stock of ParentCo, except
      that, to the extent that state law provides rights to dissenting
      shareholders, those SDG&E shareholders who exercise dissenters' rights in
      the statutorily prescribed manner ("Dissenters") will be paid by SDG&E an
      amount equal to the fair market value of their shares at the time
      immediately preceding the announcement of the merger or value as
      determined by judicial proceedings, if the parties disagree.  The 100
      shares of MergeCo common stock issued to ParentCo will automatically be
      converted into all of the issued and outstanding common stock of SDG&E.
      The 100 shares of ParentCo common stock issued to SDG&E will be canceled
      in the merger.  The shares of Preferred Stock and Preference Stock issued
      and outstanding immediately before the merger will not be affected by the
      merger, but will remain issued and outstanding shares of SDG&E preferred
      stock entitled to the same respective relative rights and preferences as
      presently provided.

           As a result of Steps 5 and 6, the SDG&E common shareholders other
      than Dissenters (the "Transferors") will own all of the outstanding stock
      of ParentCo and ParentCo will directly own all of the outstanding common
      stock of SDG&E, Califia, Enova, PDCC and EEMI and all of the outstanding
      preferred stock of Califia presently owned by SDG&E.

      San Diego Gas & Electric Company

           We understand and assume the following:

           (a)  No stock or securities will be issued for services rendered to
      or for the benefit of ParentCo in connection with the proposed
      transaction, and no stock or securities will be issued for indebtedness of
      ParentCo.

           (b)  The transfer is not the result of the solicitation by a 
      promoter, broker, or investment house.

           (c)  The Transferors will not retain any rights in the property
      transferred to ParentCo.

           (d)  ParentCo will not assume any liabilities of the Transferors and
      the stock being transferred is not subject to any liabilities.

           (e)  There is no indebtedness between ParentCo and any Transferor and
      there will be no indebtedness created in favor of any Transferor as a
      result of the transaction.

           (f)  The transfers and exchanges will occur under a plan agreed upon
      before the transaction in which the rights of the parties are defined.

           (g)  All exchanges will occur on approximately the same date.

           (h)  With the exception of incorporation shares issued to SDG&E which
      will be canceled upon consummation of the transaction, there is no plan or
      intention on the part of ParentCo to redeem or otherwise reacquire any
      stock or indebtedness to be issued in the proposed transaction.

           (i)  There is no plan or intention for ParentCo to issue additional
      shares of ParentCo stock, except pursuant to the Common Stock Investment
      Plan (the "CSIP") and various employee benefit plans presently maintained
      by SDG&E.  In the past, such issuances have in the aggregate amounted
      annually to less than one percent of the outstanding shares of SDG&E
      Common Stock.  There is no plan or intent for future issuances pursuant to
      the CSIP and the employee benefit plans to exceed historical levels and it
      is not anticipated that such issuances will exceed historical levels.

           (j)  To the best knowledge of management, there is no plan or
      intention on the part of the Transferors to sell, exchange, transfer by
      gift, or otherwise dispose of any of the stock of ParentCo to be received
      in the exchange.

           (k)  Each Transferor will receive ParentCo common stock approximately
      equal to the fair market value of the SDG&E common stock transferred to
      ParentCo.
<PAGE>
 
      San Diego Gas & Electric Company
      February 17, 1995
      Page 5


           (l)  ParentCo will remain in existence as a holding company, as
      described above.

           (m)  There is no plan or intention by ParentCo to dispose of any
      SDG&E stock, or any assets of SDG&E whose value exceeds in the aggregate
      five percent of the shareholders' equity in SDG&E, other than in the
      normal course of business operations. No such asset sale is being
      considered as part of the proposed transaction. The proceeds from any such
      sale would not be distributed to the shareholders of either ParentCo or
      SDG&E (other than ParentCo).

           (n)  Each of the parties to the transaction will pay their own
      expenses, if any, incurred in connection with the proposed transaction.

           (o)  ParentCo will not be a regulated investment company (a "RIC") or
      a real estate investment trust (a "REIT"), and ParentCo will not hold
      readily marketable stocks or securities for investment or interests in
      RICs or REITs the value of which in the aggregate exceeds 80 percent of
      the value of ParentCo's assets.

           (p)  To the best knowledge of management, no Transferor is under the
      jurisdiction of a court in a title 11 or similar case (within the meaning
      of section 368(a)(3)(A)) and the stock or securities received in the
      exchange will not be used to satisfy the indebtedness of such debtor,
      except that Dr. Ralph R. Ocampo, a director who holds 13,128 shares
      jointly with spouse/children, petitioned for protection under Chapter 11
      of the Federal Bankruptcy Code in March 1993.


           Additionally, we assume (1) the accuracy of the Agreement; and (2)
      the accuracy of all factual statements and representations made in our
      December 19, 1994 IRS private letter ruling request and any supplements
      thereto.  Finally, we assume, and this opinion is conditioned on, the
      receipt by SDG&E of a private letter ruling from the IRS ruling that the
      formation of MergeCo and its merger with and into SDG&E will be
      disregarded for federal income tax purposes, and the transaction will be
      treated as a transfer by the Transferors of their SDG&E common stock to
      ParentCo solely in exchange for an equal number of shares of common stock
      of ParentCo.

           In light of the foregoing, and based solely on the information,
      understandings and assumptions described herein, and assuming no material
      changes in such information, understandings and assumptions nor in the
      applicable law prior to consummation of the proposed transaction, our
      opinion is as follows with respect to Step 5:

           (i)  No gain or loss will be recognized to the Transferors upon the
                transfer of their SDG&E common stock to ParentCo solely in
                exchange for shares of ParentCo common stock (section 351(a)).
<PAGE>
 
      San Diego Gas & Electric Company
      February 17, 1995
      Page 6


           (ii)  No gain or loss will be recognized by ParentCo upon the receipt
                 of the SDG&E common stock solely in exchange for shares of
                 ParentCo common stock (section 1032(a)).

           (iii) The basis of the ParentCo common stock to be received by the
                 Transferors in the transaction will be the same as the basis of
                 the SDG&E common stock surrendered in exchange therefor
                 (section 358(a)(1)).

           (iv)  The holding period of the ParentCo common stock to be received
                 by the Transferors will include the period during which the
                 SDG&E common stock was held, provided that the SDG&E common
                 stock was held as a capital asset on the date of the exchange
                 (section 1223(1)).

           (v)   The basis of the SDG&E common stock to be received by ParentCo
                 will be the same as the basis of the stock in the hands of the
                 exchanging Transferors (section 362(a)).

           (vi)  The holding period of the SDG&E common stock to be received by
                 ParentCo will include the period during which such stock was
                 held by the Transferors (section 1223(2)).

           No opinion is expressed about the tax treatment of the transactions
      described in Steps 1, 2, 3, 4 and 6.  Further, no opinion is expressed
      about the tax treatment of the transaction under other provisions of the
      Internal Revenue Code and implementing regulations or about the tax
      treatment of any conditions existing at the time of, or effects resulting
      from, the transaction that are not specifically covered by the above
      opinions.

           The opinions rendered herein are based on provisions of the Internal
      Revenue Code of 1986, as amended as of the date hereof, regulations
      promulgated pursuant thereto, reported judicial decisions and published
      administrative rulings.  Judicial, legislative or administrative changes
      may be forthcoming that would require modification of some or all of the
      conclusions reached in those opinions and you should be aware that any
      such changes may be applicable retroactively.

           We hereby consent to the filing of this opinion as an exhibit to the
      Registration Statement and to the reference to our firm under the caption
      "Formation of a Holding Company - Federal Income Tax Consequences of the
      Merger" in the Registration Statement.

      April __, 1995



      Dear Fellow Shareholder:

      Some time ago, we mailed you a proxy statement and prospectus and a proxy
      for the annual shareholders meeting of Tuesday, April 25.

      Since the company has not yet received your signed proxy, I am enclosing a
      second proxy with this letter, in the event you have misplaced the first
      one.

      We are hoping to have as large a representation of shareholders as
      possible at the meeting.  Therefore, please sign the enclosed proxy and
      return it in the accompanying prepaid envelope.  In this way, you will be
      assured that your shares will be represented at the shareholders meeting.

      Please do not hesitate to let me know if you have any questions or
      comments about the operation of your company.  Your interest in San Diego
      Gas & Electric is always most welcome.


      Sincerely,



      Thomas A. Page



                          ----------------------------

                         IF YOUR PROXY HAS BEEN MAILED
                      NO ACTION IS NECESSARY ON YOUR PART

                          ----------------------------
