                               PG&E CORPORATION
                          LONG-TERM INCENTIVE PROGRAM
                (As amended effective as of February 16, 2000)


1.   Purpose of the Program
     ----------------------

     This is the controlling and definitive statement of the PG&E Corporation
     Long-Term Incentive Program, as amended and restated herein (hereinafter
     called the PROGRAM/1/).  The purpose of the PROGRAM is to advance the
     interests of the CORPORATION by providing ELIGIBLE PARTICIPANTS with
     financial incentives to promote the success of its long-term (five to ten
     years) business objectives, and to increase their proprietary interest in
     the success of the CORPORATION.  It is the intent of the CORPORATION to
     reward those ELIGIBLE PARTICIPANTS who have a significant impact on
     improved long-term corporate achievements.  Inasmuch as the PROGRAM is
     designed to encourage financial performance and to improve the value of
     shareholders' investment in PG&E CORPORATION, the costs of the PROGRAM will
     be funded from corporate earnings.

     BOARD OF DIRECTORS.  Subject to the provisions of the PROGRAM, the
     COMMITTEE or the BOARD OF DIRECTORS, as the case may be, shall have full
     and final authority, in its sole discretion:

     (a)  to determine the ELIGIBLE PARTICIPANTS to whom INCENTIVE AWARDS shall
          be granted and the number of shares of COMMON STOCK to be awarded
          under each INCENTIVE AWARD, based on the recommendation of the CHIEF
          EXECUTIVE OFFICER (except that awards to the CHIEF EXECUTIVE OFFICER
          shall be based on the recommendation of the BOARD OF DIRECTORS and
          awards to NON-EMPLOYEE DIRECTORS shall be based on the recommendation
          of the COMMITTEE);

     (b)  to determine the time or times at which INCENTIVE AWARDS shall be
          granted;

     (c)  to designate the types of INCENTIVE AWARD being granted;

          but not limited to, the consideration and method of payment for shares
          purchased upon the exercise of an INCENTIVE AWARD, and any vesting
          acceleration or exercisability provisions in the event of a CHANGE IN

          to any INCENTIVE AWARD or the exercise or realization thereof;

     (i)  except as provided in Section 18 hereof, to prescribe, amend and
          rescind rules, regulations and policies relating to the administration
          of the PROGRAM;

     (j)  except as provided in Section 18 hereof, to suspend, terminate, modify
          or amend the PROGRAM;

     (k)  to delegate to one or more agents such administrative duties as the
          COMMITTEE or BOARD OF DIRECTORS may deem advisable, to the extent
          permitted by applicable law; and

          respect to the PROGRAM and any INCENTIVE AWARD granted hereunder as
          the COMMITTEE may deem advisable, to the extent permitted by
          applicable law.

     Notwithstanding the provisions contained in the foregoing paragraph, the
     CHIEF EXECUTIVE OFFICER shall have the authority, in his sole discretion:
     (a) to grant INCENTIVE AWARDS to any ELIGIBLE PARTICIPANT who, at the time
     of the INCENTIVE AWARD grant, (i) is not an officer of the CORPORATION or a
     DIRECTOR, and (ii) if such ELIGIBLE PARTICIPANT is an EMPLOYEE, is
     receiving an annual salary which is below the level which requires approval
     by the COMMITTEE; (b) to determine the time or times at which INCENTIVE
     AWARDS shall be granted to such ELIGIBLE PARTICIPANTS; (c) to designate the

<PAGE>

     PARTICIPANTS; and (d) to vary the OPTION vesting schedule described in the
     STOCK OPTION PLAN for the OPTIONS granted to such ELIGIBLE PARTICIPANTS;
     provided, however, that all grants of INCENTIVE AWARDS by the CHIEF
     EXECUTIVE OFFICER shall conform to the guidelines previously approved by
     the COMMITTEE.

3.   Shares of Stock Subject to the Program
     --------------------------------------

     There shall be reserved for use under the PROGRAM (subject to the
     provisions of Section 13 hereof) a total of 34,389,230 shares of COMMON
     STOCK, which shares may be authorized but unissued shares of COMMON STOCK
     or issued shares of COMMON STOCK which shall have been reacquired by PG&E
     CORPORATION.  Such shares consist of (i) 13,000,000 shares of COMMON STOCK
     originally reserved for use under the PROGRAM at the time it first became
     effective on January 1, 1992, (ii) 389,230 shares of COMMON STOCK remaining
     under the 1986 OPTION PLAN and carried over to the PROGRAM, (iii)
     10,000,000 shares of COMMON STOCK added to the PROGRAM effective as of
     January 1, 1996, and (iv) 11,000,000 shares of COMMON STOCK added to the
     PROGRAM effective as of April 21, 1999.

     If (i) any INCENTIVE AWARD expires or terminates for any reason without
     having been exercised or purchased in full, (ii) an INCENTIVE AWARD is
     surrendered in exchange for one or more other INCENTIVE AWARDS, or (iii)
     any RESTRICTED STOCK is forfeited, then, in each such case, any
     unexercised, unpurchased, surrendered or forfeited shares which were
     subject to such INCENTIVE AWARD (except shares as to which a related TANDEM
     SAR has been exercised) shall again be available for the future grant of
     INCENTIVE AWARDS under the PROGRAM (unless the PROGRAM has terminated).  In
     addition, shares may be reused or added back to the PROGRAM to the extent
     permitted by applicable law.

4.   Eligibility
     -----------

     INCENTIVE AWARDS will be granted only to ELIGIBLE PARTICIPANTS.  ISOS will
     be granted only to EMPLOYEES.  The COMMITTEE, in its sole discretion, may
     grant INCENTIVE AWARDS to an ELIGIBLE PARTICIPANT who is a resident or
     citizen of a foreign country, with such modifications as the COMMITTEE may
     deem advisable to reflect the laws, tax policy or customs of such foreign
     country.

     The PROGRAM shall not confer upon any RECIPIENT any right to continuation
     of employment, service as a DIRECTOR or consulting relationship with the
     CORPORATION; nor shall it interfere in any way with the right of the
     RECIPIENT or the CORPORATION to terminate such employment, service as a
     DIRECTOR or consulting relationship at any time, with or without cause.

5.   Designation of Incentive Awards
     -------------------------------

     At the time of the grant of each INCENTIVE AWARD under the Program, the
     COMMITTEE (or the CHIEF EXECUTIVE OFFICER, in the case of INCENTIVE AWARDS
     granted by the CHIEF EXECUTIVE OFFICER to certain ELIGIBLE PARTICIPANTS
     pursuant to Section 2 hereof, or the BOARD OF DIRECTORS, in the case of
     INCENTIVE AWARDS granted by the BOARD OF DIRECTORS to NON-EMPLOYEE
     DIRECTORS) shall determine whether such INCENTIVE AWARD is to be designated
     as an ISO, NON-QUALIFIED STOCK OPTION, SAR, DIVIDEND EQUIVALENT,
     PERFORMANCE UNIT, stock grant, RESTRICTED STOCK, LSAR, PHANTOM STOCK or
     other STOCK-BASED AWARD; provided, however, that ISOS may be granted only
     to EMPLOYEES.

     Notwithstanding such designation, to the extent that the aggregate FAIR
     MARKET VALUE (determined for each share as of the date of grant of the
     OPTION covering each share) of the shares with respect to which OPTIONS
     designated as ISOS become exercisable for the first time by any RECIPIENT
     during any calendar year exceeds $100,000, such OPTIONS shall be treated as
     NON-QUALIFIED STOCK OPTIONS.

     Any INCENTIVE AWARD may be granted alone, contingent upon, in addition to
     or in TANDEM with one or more other INCENTIVE AWARDS granted under the
     PROGRAM.  In addition, except as provided in Section 12 hereof, any
     INCENTIVE AWARD may be granted in exchange for one or more other INCENTIVE
     AWARDS.

6.   Stock Options, Tandem Stock Appreciation Rights and Tandem Dividend

     AWARDS to NON-EMPLOYEE DIRECTORS), the COMMITTEE, in its sole discretion,
     may grant ISOS, NON-QUALIFIED STOCK OPTIONS, TANDEM SARS and TANDEM
     DIVIDEND EQUIVALENTS to ELIGIBLE PARTICIPANTS, subject to the terms and
     conditions set forth in the STOCK OPTION PLAN attached hereto as Exhibit A.

     Except as provided in Section 9 below (relating to grants of INCENTIVE

     and conditions set forth in the PERFORMANCE UNIT PLAN attached hereto as

                                       4
<PAGE>

     Except as provided in Section 9 below (relating to grants of INCENTIVE
     AWARDS to NON-EMPLOYEE DIRECTORS), the COMMITTEE, in its sole discretion,
     may grant other INCENTIVE AWARDS (including, but not limited to, SARS
     granted without OPTIONS, DIVIDEND EQUIVALENTS granted without OPTIONS,
     stock grants, RESTRICTED STOCK, LSARS, PHANTOM STOCK or other STOCK-BASED
     AWARDS) to ELIGIBLE PARTICIPANTS, subject to such terms and conditions as
     the COMMITTEE shall deem appropriate.

9.   Grants of Incentive Awards to Non-Employee Directors
     ----------------------------------------------------

     NON-EMPLOYEE DIRECTORS will only be eligible to be granted DIRECTOR
     RESTRICTED STOCK, PHANTOM STOCK and NON-QUALIFIED STOCK OPTIONS in
     accordance with, and subject to the terms and conditions contained in, the
     NON-EMPLOYEE DIRECTOR STOCK INCENTIVE PLAN RULES attached hereto as Exhibit
     C.

10.  Termination of Employment or Relationship with the CORPORATION
     --------------------------------------------------------------

     The COMMITTEE may, in its sole discretion, establish terms and conditions
     pertaining to the effect of TERMINATION on INCENTIVE AWARDS granted to a
     RECIPIENT prior to TERMINATION, to the extent permitted by applicable law.

11.  Tax Withholding
     ---------------

     When a RECIPIENT incurs tax liability in connection with the exercise of an
     INCENTIVE AWARD or the receipt of shares of COMMON STOCK pursuant to an
     INCENTIVE AWARD, which tax liability is subject to tax withholding under
     applicable tax laws, and the RECIPIENT is obligated to pay the CORPORATION
     an amount required to be withheld under applicable tax laws, the RECIPIENT
     may satisfy the withholding tax obligation by (i) electing to have the
     CORPORATION withhold such amount from his or her current compensation
     through payroll deductions, or (ii) making a direct payment to the
     CORPORATION in cash or by check.

     The COMMITTEE may, in its sole discretion, permit a RECIPIENT to satisfy
     all or part of his or her withholding tax obligations by having the
     CORPORATION withhold from the shares to be issued to the RECIPIENT that
     number of shares having a FAIR MARKET VALUE equal to the amount required to
     be withheld determined on the date when taxes otherwise would be withheld
     in cash.  The payment of withholding taxes in this manner, if permitted by
     the COMMITTEE, shall be subject to such restrictions as the COMMITTEE may
     impose, including any restrictions required by rules of the Securities and
     Exchange Commission.

                                       5

12.  Replacement of Grants
     ---------------------

     The COMMITTEE may, in its sole discretion, offer a RECIPIENT (other than
     NON-EMPLOYEE DIRECTORS) the option of surrendering an unexercised OPTION or
     other INCENTIVE AWARD in exchange for another INCENTIVE AWARD of the same
     type or for a different type of INCENTIVE AWARD; provided, however, that no
     OPTION or INCENTIVE AWARD may be exchanged for a new OPTION or INCENTIVE
     AWARD having an OPTION PRICE or purchase price that is lower than the
     OPTION PRICE or purchase price of the original OPTION or INCENTIVE AWARD.

13.  Deferral of Payments
     --------------------

     The COMMITTEE may, in its sole discretion, approve a RECIPIENT'S deferral
     of any cash payments which may become due under the PROGRAM.  Such
     deferrals shall be subject to any conditions, restrictions or requirements
     as the COMMITTEE may determine.

14.  Adjustments Upon Changes in Number or Value of Shares of Common Stock
     ---------------------------------------------------------------------

     If there are any changes in the number or value of shares of COMMON STOCK
     by reason of stock dividends, stock splits, reverse stock splits,
     recapitalizations, mergers, consolidations or other events that materially
     increase or decrease the number or value of issued and outstanding shares
     of COMMON STOCK, the COMMITTEE may make such adjustments as it shall deem
     appropriate, in order to prevent dilution or enlargement of rights.

15.  Non-Transferability of Incentive Awards
     ---------------------------------------

     An INCENTIVE AWARD shall not be transferable by the RECIPIENT otherwise
     than by will or the laws of descent and distribution, or pursuant to a
     qualified domestic relations order as defined by the CODE, Title I of ERISA
     or the rules thereunder.  During the lifetime of the RECIPIENT, an
     INCENTIVE AWARD may be exercised only by the RECIPIENT or by an alternate
     payee under a qualified domestic relations order.

16.  Change in Control
     -----------------

     Upon the occurrence of a CHANGE IN CONTROL (as defined below):

     (a)  Any time periods relating to the exercise or realization of any
          INCENTIVE AWARD granted hereunder shall be accelerated so that such
          INCENTIVE AWARD may be immediately exercised or realized in full;

     (b)  All shares of RESTRICTED STOCK granted hereunder shall immediately
          cease to be forfeitable; and

                                       6
<PAGE>

     (c)  All conditions relating to the realization of any STOCK-BASED AWARD
          granted hereunder shall immediately terminate.

     A "CHANGE IN CONTROL" shall be deemed to have occurred if:

     (a)  any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
          the EXCHANGE ACT, but excluding any benefit plan for EMPLOYEES or any
          trustee, agent or other fiduciary for any such plan acting in such
          person's capacity as such fiduciary), directly or indirectly, becomes
          the beneficial owner of securities of the CORPORATION representing
          twenty percent (20%) or more of the combined voting power of the
          CORPORATION's then outstanding securities;

     (b)  during any two consecutive years, individuals who at the beginning of
          such a period constitute the BOARD OF DIRECTORS cease for any reason
          to constitute at least a majority of the BOARD OF DIRECTORS, unless
          the election, or the nomination for election by the shareholders of
          the CORPORATION, of each new DIRECTOR was approved by a vote of at
          least two-thirds (2/3) of the DIRECTORS then still in office who were
          DIRECTORS at the beginning of the period; or

     (c)  the shareholders of the CORPORATION shall have approved (i) any
          consolidation or merger of the CORPORATION other than a merger or
          consolidation which would result in the voting securities of the
          CORPORATION outstanding immediately prior thereto continuing to
          represent (either by remaining outstanding or by being converted into
          voting securities of the surviving entity or any parent of such
          surviving entity) at least 70 percent of the Combined Voting Power of
          the CORPORATION, such surviving entity or the parent of such surviving
          entity outstanding immediately after the merger or consolidation; (ii)
          any sale, lease, exchange or other transfer (in one transaction or a
          series of related transactions) of all or substantially all of the
          assets of the CORPORATION, or (iii) any plan or proposal for the
          liquidation or dissolution of the CORPORATION. For purposes of this
          paragraph, the term Combined Voting Power shall mean the combined
          voting power of the CORPORATION's or other relevant entity's then
          outstanding voting securities.

17.  Listing and Registration of Shares
     ----------------------------------

     Each INCENTIVE AWARD shall be subject to the requirement that if at any
     time the COMMITTEE shall determine, in its discretion, that the listing,
     registration or qualification of the shares covered thereby under any
     securities exchange or under any state or federal law or the consent or
     approval of any governmental regulatory body, including the California
     Public Utilities Commission, is necessary or desirable as a condition of,
     or in connection with, the granting of such

                                       7
<PAGE>

     INCENTIVE AWARD or the issue or purchase of shares thereunder, such
     INCENTIVE AWARD may not be exercised in whole or in part unless and until
     such listing, registration, qualification, consent or approval shall have
     been effected or obtained free of any conditions not acceptable to the
     COMMITTEE.

18.  Amendment and Termination of the Program and Incentive Awards
     -------------------------------------------------------------

     The BOARD OF DIRECTORS or the COMMITTEE may at any time suspend, terminate,
     modify or amend the PROGRAM in any respect; provided, however, that to the
     extent necessary and desirable to comply with Section 422 of the CODE (or
     any other applicable law or regulation, including the requirements of any
     stock exchange on which the COMMON STOCK is listed or quoted), shareholder
     approval of any PROGRAM amendment shall be obtained in such a manner and to
     such a degree as is required by the applicable law or regulation.

     No suspension, termination, modification or amendment of the PROGRAM may,
     without the consent of the RECIPIENT, adversely affect his or her rights
     under INCENTIVE AWARDS theretofore granted to such RECIPIENT.  In the event
     of amendments to the CODE or applicable rules or regulations relating to
     ISOS subsequent to the date hereof, the CORPORATION may amend the PROGRAM,
     and the CORPORATION and RECIPIENTS holding OPTION agreements may agree to
     amend outstanding OPTION agreements, to conform to such amendments.

     The BOARD OF DIRECTORS or COMMITTEE may make such amendments or
     modifications in the terms and conditions of any INCENTIVE AWARD as it may
     deem advisable, or cancel or annul any grant of an INCENTIVE AWARD;
     provided, however, that no such amendment, modification, cancellation or
     annulment may, without the consent of the RECIPIENT, adversely affect his
     or her rights under such INCENTIVE AWARD; and provided further the BOARD OF
     DIRECTORS or COMMITTEE may not reduce the OPTION PRICE or purchase price of
     any OPTION or INCENTIVE AWARD below the original OPTION PRICE or purchase
     price.

     Notwithstanding the foregoing, the BOARD OF DIRECTORS or COMMITTEE reserves
     the right, in its sole discretion, to (i) convert any outstanding ISOS to
     NON-QUALIFIED STOCK OPTIONS, (ii) to require a RECIPIENT to forfeit any
     unexercised or unpurchased INCENTIVE AWARDS, any shares received or
     purchased pursuant to an INCENTIVE AWARD, or any gains realized by virtue
     of the receipt of an INCENTIVE AWARD in the event that such RECIPIENT
     competes against the CORPORATION, and (iii) to cancel or annul any grant of
     an INCENTIVE AWARD in the event of a RECIPIENT'S TERMINATION FOR CAUSE.
     For purposes of the PROGRAM, "TERMINATION FOR CAUSE" shall include, but not
     be limited to, termination because of dishonesty, criminal offense or
     violation of a work rule, and shall be determined by, and in the sole
     discretion of, the BOARD OF DIRECTORS or COMMITTEE.

                               STOCK OPTION PLAN
                (As amended effective as of February 16, 2000)


1.   Purpose of the Plan
     -------------------

     This is the controlling and definitive statement of the PG&E Corporation
     Stock Option Plan set forth herein and as may be amended from time to time
     (hereinafter called the PLAN/2/). The purpose of the PLAN is to advance the
     interests of the CORPORATION by providing ELIGIBLE PARTICIPANTS with
     financial incentives to promote the success of its long-term (five to ten
     years) business objectives, and to increase their proprietary interest in
     the success of the CORPORATION. It is the intent of the CORPORATION to
     reward those ELIGIBLE PARTICIPANTS who have a significant impact on
     improved long-term corporate achievements. Inasmuch as the PLAN is designed
     to encourage financial performance and to improve the value of
     shareholders' investment in PG&E CORPORATION, the costs of the PLAN will be
     funded from corporate earnings.

2.   Plan Administration
     -------------------

     The PLAN shall be administered by the COMMITTEE, which shall be constituted
     in such a manner as to comply with the rules governing a plan intended to
     qualify as a discretionary plan under RULE 16b-3.

     Subject to the provisions of the PLAN, the COMMITTEE shall have full and
     final authority, in its sole discretion:

     (a)  to determine the ELIGIBLE PARTICIPANTS to whom OPTIONS shall be
          granted and the number of shares of COMMON STOCK to be awarded under
          each OPTION, based on the recommendation of the CHIEF EXECUTIVE
          OFFICER (except that awards to the CHIEF EXECUTIVE OFFICER shall be
          shall be based on the recommendation of the BOARD OF DIRECTORS);
          provided, however, that the number of shares of COMMON STOCK to be
          awarded under each OPTION shall be subject to the limitations
          specified in Section 5 hereof;

     (b)  to determine the time or times at which OPTIONS shall be granted;

_____________
/2/ Capitalized words are defined in Section 20 hereof.

                                       14
<PAGE>

     (c)  to designate the OPTIONS being granted as ISOS or NON-QUALIFIED STOCK
          OPTIONS;

     (d)  to vary the OPTION vesting schedule described in Section 11 hereof;

     (e)  to determine the terms and conditions, not inconsistent with the terms
          of the PLAN, of any OPTION granted hereunder (including, but not
          limited to, the consideration and method of payment for shares
          purchased upon the exercise of an OPTION, and any vesting acceleration
          or exercisability provisions in the event of a CHANGE IN CONTROL or
          TERMINATION), based in each case on such factors as the COMMITTEE
          shall deem appropriate;

     (f)  to approve forms of agreement for use under the PLAN;

     (g)  to construe and interpret the PLAN and any related OPTION agreement
          and to define the terms employed herein and therein;

     (h)  except as provided in Section 18 hereof, to modify or amend any OPTION
          or to waive any restrictions or conditions applicable to any OPTION or
          the exercise thereof;

     (i)  except as provided in Section 18 hereof, to prescribe, amend and
          rescind rules, regulations and policies relating to the administration
          of the PLAN;

     (j)  except as provided in Section 18 hereof, to suspend, terminate, modify
          or amend the PLAN;

     (k)  to delegate to one or more agents such administrative duties as the
          COMMITTEE may deem advisable, to the extent permitted by applicable
          law; and

     (l)  to make all other determinations and take such other action with
          respect to the PLAN and any OPTION granted hereunder as the COMMITTEE
          may deem advisable, to the extent permitted by applicable law.

     Notwithstanding the provisions contained in the foregoing paragraph, the
     CHIEF EXECUTIVE OFFICER shall have the authority, in his sole discretion:
     (a) to grant OPTIONS to any ELIGIBLE PARTICIPANT who, at the time of the
     OPTION grant, (i) is not an officer of the CORPORATION or a DIRECTOR, and
     (ii) if such ELIGIBLE PARTICIPANT is an EMPLOYEE, is receiving an annual
     salary which is below the level which requires approval by the COMMITTEE;
     (b) to determine the time or times at which OPTIONS shall be granted to
     such ELIGIBLE PARTICIPANTS; (c) to designate the OPTIONS being granted to
     such ELIGIBLE PARTICIPANTS as ISOS or NON-QUALIFIED STOCK

                                       15
<PAGE>

     OPTIONS; and (d) to vary the OPTION vesting schedule described in Section
     11 hereof for the OPTIONS granted to such ELIGIBLE PARTICIPANTS; provided,
     however, that (x) all grants of OPTIONS by the CHIEF EXECUTIVE OFFICER
     shall conform to the guidelines previously approved by the COMMITTEE, and
     (y) the number of shares of COMMON STOCK to be awarded under each OPTION
     shall be subject to the limitations specified in Section 5 hereof.

3.   Shares of Stock Subject to the Plan
     -----------------------------------

     There shall be reserved for use under the PLAN and for the grant of any
     other incentive awards pursuant to the PROGRAM (subject to the provisions
     of Section 14 hereof) a total of 34,389,230 shares of COMMON STOCK, which
     shares may be authorized but unissued shares of COMMON STOCK or issued
     shares of COMMON STOCK which shall have been reacquired by PG&E
     CORPORATION.

     If any OPTION expires or terminates for any reason without having been
     exercised in full, then any unexercised, shares which were subject to such
     OPTION (except shares as to which a related TANDEM SAR has been exercised)
     shall again be available for the future grant of OPTIONS under the PLAN
     (unless the PLAN has terminated).  In addition, shares may be reused or
     added back to the PLAN to the extent permitted by applicable law.

4.   Eligibility
     -----------

     OPTIONS will be granted only to ELIGIBLE PARTICIPANTS.  ISOS will be
     granted only to EMPLOYEES.  The COMMITTEE, in its sole discretion, may
     grant OPTIONS to an ELIGIBLE PARTICIPANT who is a resident or citizen of a
     foreign country, with such modifications as the COMMITTEE may deem
     advisable to reflect the laws, tax policy or customs of such foreign
     country.

     The PLAN shall not confer upon any OPTIONEE any right to continuation of
     employment, service as a DIRECTOR or consulting relationship with the
     CORPORATION; nor shall it interfere in any way with the right of the
     OPTIONEE or the CORPORATION to terminate such employment, service as a
     DIRECTOR or consulting relationship at any time, with or without cause.

5.   Limitation on Options and SARs Awarded to Any Eligible Participant
     ------------------------------------------------------------------

     The aggregate number of shares of COMMON STOCK with respect to which any
     ELIGIBLE PARTICIPANT may be granted OPTIONS and SARS under the PLAN during
     any calendar year shall in no event exceed two percent (2%) of the total
     number of shares reserved for use under the PLAN.

                                       16
<PAGE>

6.   Designation of Options
     ----------------------

     At the time of the grant of each OPTION under the PLAN, the COMMITTEE (or
     the CHIEF EXECUTIVE OFFICER, in the case of OPTIONS granted by the CHIEF
     EXECUTIVE OFFICER to certain ELIGIBLE PARTICIPANTS pursuant to Section 2
     hereof) shall determine whether such OPTION is to be designated as an ISO
     or a NON-QUALIFIED STOCK OPTION; provided, however, that ISOS may be
     granted only to EMPLOYEES.

     Notwithstanding such designation, to the extent that the aggregate FAIR
     MARKET VALUE (determined for each share as of the date of grant of the
     OPTION covering each share) of the shares with respect to which OPTIONS
     designated as ISOS become exercisable for the first time by any OPTIONEE
     during any calendar year exceeds $100,000, such OPTIONS shall be treated as
     NON-QUALIFIED STOCK OPTIONS.

7.   Option Price
     ------------

     The OPTION PRICE of the COMMON STOCK under each OPTION issued shall be the
     FAIR MARKET VALUE of the COMMON STOCK on the date of grant.

8.   Stock Appreciation Rights
     -------------------------

     At the discretion of the COMMITTEE, an OPTION may be granted with or
     without a TANDEM SAR which permits the OPTIONEE to surrender unexercised an
     OPTION or portion thereof and to receive in exchange a payment having a
     value equal to the difference between (x) the FAIR MARKET VALUE of the
     COMMON STOCK covered by the surrendered portion of the OPTION on the date
     the SAR is exercised and (y) the OPTION PRICE for such COMMON STOCK.  The
     SAR is subject to the same terms and conditions as the related OPTION,
     except that (i) the SAR may be exercised only when there is a positive
     spread (i.e., when the FAIR MARKET VALUE of the COMMON STOCK subject to the
     OPTION exceeds the OPTION PRICE), (ii) in accordance with Section 9 hereof,
     payment of the DEA (if any) to the OPTIONEE may be restricted, and (iii) if
     the OPTIONEE is a SECTION 16 OFFICER, DIRECTOR or other person whose
     transactions in the COMMON STOCK are subject to Section 16(b) of the
     EXCHANGE ACT, the SAR may be exercised only during the period beginning on
     the third (3rd) business day following the date of release of the
     CORPORATION's quarterly or annual statement of earnings and ending on the
     twelfth (12th) business day following such date.  Upon the exercise of a
     SAR, the number of shares subject to exercise under the related OPTION
     shall be automatically reduced by the number of shares represented by the
     OPTION or portion thereof surrendered.  No payment will be required from
     the OPTIONEE upon the exercise of a SAR, except that any amount necessary
     to satisfy applicable federal, state or local tax requirements shall be
     withheld.

                                       17
<PAGE>

9.   Dividend Equivalent Account
     ---------------------------

     At the discretion of the COMMITTEE, an OPTION may be granted with or
     without TANDEM DIVIDEND EQUIVALENTS.  When an OPTION is granted with TANDEM
     DIVIDEND EQUIVALENTS, a Dividend Equivalent Account ("DEA") shall be
     established for the OPTIONEE.  This DEA shall be credited quarterly on each
     dividend record date with dividends which would have been paid on the
     COMMON STOCK subject to the unexercised portion of the OPTION (including
     any portion which has not yet vested on the record date), if such portion
     had been exercised.  Except as provided in Section 12(d) hereof, at the
     time the OPTION or any related SAR is exercised, the OPTIONEE shall receive
     all funds which have accumulated in the DEA with respect to the shares of
     COMMON STOCK for which the OPTION or SAR is being exercised; provided,
     however, that if the OPTIONEE exercises a SAR, such DEA funds shall only be
     paid to the OPTIONEE if (i) the percentage increase in the FAIR MARKET
     VALUE of the COMMON STOCK over the OPTION PRICE averages at least five
     percent (5%) per year for the first five (5) years after the grant, or (ii)
     in the case of OPTIONS held for longer than five (5) years from the date of
     grant, such FAIR MARKET VALUE has increased by at least twenty-five percent
     (25%) over the OPTION PRICE.

10.  Terms of Options
     ----------------

     The term of each ISO shall be for ten (10) years from the date of grant,
     subject to earlier termination as provided in Section 12 hereof.  The term
     of each NON-QUALIFIED STOCK OPTION shall be ten (10) years and one (1) day
     from the date of grant, subject to earlier termination as provided in
     Section 12 hereof.  Any provision of the PROGRAM to the contrary
     notwithstanding, no OPTION shall be exercised after the time limitations
     stated in this Section 10.

11.  Limitations on Exercise
     -----------------------

     (a)  Each OPTION granted under the PROGRAM shall become exercisable and
          vested only to the following extent:  (i) up to one-third (1/3) of the
          OPTIONS granted may be exercised on or after the second (2nd)
          anniversary of the date of grant; (ii) up to two-thirds (2/3) of the
          OPTIONS granted may be exercised on or after the third (3rd)
          anniversary of the date of grant; and (iii) up to one hundred percent
          (100%) of the OPTIONS granted may be exercised on or after the fourth
          (4th) anniversary of the date of grant.

     (b)  No OPTION under the PROGRAM designated by the COMMITTEE as an ISO and
          granted before January 1, 1987 may be exercised while there is
          outstanding in the hands of the OPTIONEE any ISO which was granted

                                       18
<PAGE>

          before the granting of the ISO hereunder sought to be exercised.  For
          this purpose an ISO shall be treated as outstanding until such OPTION
          is (i) exercised in full, (ii) surrendered in full by exercising SARS
          pursuant to Section 8 hereof, or (iii) rendered void by reason of
          lapse of time.

12.  Termination of Employment or Relationship with the CORPORATION
     --------------------------------------------------------------

     (a)  In the event of a TERMINATION by reason of a discharge or TERMINATION
          FOR CAUSE, any unexercised OPTIONS theretofore granted to an OPTIONEE
          under the PROGRAM shall forthwith terminate.

     (b)  In the event of a TERMINATION by reason of RETIREMENT, all OPTIONS
          held by the OPTIONEE, to the extent that such OPTIONS have not
          previously expired or been exercised, shall become fully exercisable
          and vested, notwithstanding the provisions of Section 11(a) hereof,
          and the OPTIONEE shall have the right to exercise such OPTIONS in full
          at any time within their respective terms or within five (5) years
          after such RETIREMENT, whichever is shorter.  This five-year period
          shall be extended if an OPTIONEE remains on the BOARD OF DIRECTORS
          after RETIREMENT.  In such case, the OPTIONS may be exercised as long
          as the OPTIONEE remains a DIRECTOR and for a period of six (6) months
          thereafter, or within five (5) years after RETIREMENT, whichever is
          longer; provided, however, that no OPTION may be exercised after the
          expiration of its term.  To the extent any ISO held by the OPTIONEE is
          exercised after the expiration of three (3) months after such
          TERMINATION, the exercise will be deemed to involve the exercise of a
          NON-QUALIFIED STOCK OPTION.

     (c)  In the event of a TERMINATION by reason of disability or death, all
          OPTIONS held by the OPTIONEE, to the extent that such OPTIONS have not
          previously expired or been exercised, shall become fully exercisable
          and vested, notwithstanding the provisions of Section 11(a) hereof,
          and the OPTIONEE (or the OPTIONEE'S estate or a person who acquired
          the right to exercise such OPTIONS by bequest or inheritance) shall
          have the right to exercise such OPTIONS at any time within their
          respective terms or within one (1) year after the date of such
          TERMINATION, whichever is shorter.  The term "disability" shall, for
          the purposes of the PLAN, be defined in Section 22(e)(3) of the CODE.

     (d)  In the event of a TERMINATION by reason of a divestiture or change in
          control of a subsidiary of PG&E CORPORATION, which divestiture or
          change in control results in such subsidiary no longer qualifying as a
          subsidiary corporation under Section 424(f) of the CODE, all OPTIONS
          held by the OPTIONEE, to the extent that such OPTIONS have not
          previously expired or been exercised, shall become fully exercisable
          and

                                       19
<PAGE>

          vested, notwithstanding the provisions of Section 11(a) hereof, and
          the OPTIONEE shall have the right to exercise such OPTIONS in full at
          any time within their respective terms or within three (3) years after
          such TERMINATION, whichever is shorter. This three-year period shall
          be extended if an OPTIONEE remains on the BOARD OF DIRECTORS after
          such TERMINATION. In such case, the OPTIONS may be exercised as long
          as the OPTIONEE remains a DIRECTOR and for a period of six (6) months
          thereafter, or within three (3) years after such TERMINATION,
          whichever is longer; provided, however, that no OPTION may be
          exercised after the expiration of its term. To the extent any ISO held
          by the OPTIONEE is exercised after the expiration of three (3) months
          after such TERMINATION, the exercise will be deemed to involve the
          exercise of a NON-QUALIFIED STOCK OPTION.

     (e)  In the event of a TERMINATION within one year after a CHANGE IN
          CONTROL of the CORPORATION (other than a TERMINATION covered by
          clauses (a), (b), or (c) above), OPTIONEE shall have the right to
          exercise OPTIONS which OPTIONEE then holds (which OPTIONS will have
          been accelerated previously in accordance with Section 16 below), to
          the extent that such OPTIONS have not previously expired or been
          exercised, in full at any time within their respective terms or within
          three (3) years after such TERMINATION, whichever is shorter.  This
          three-year period shall be extended if an OPTIONEE remains on the
          BOARD OF DIRECTORS after such TERMINATION.  In such case, the OPTIONS
          may be exercised as long as the OPTIONEE remains a DIRECTOR and for a
          period of six (6) months thereafter, or within three (3) years after
          such TERMINATION, whichever is longer; provided, however, that no
          OPTION may be exercised after the expiration of its term.  To the
          extent any ISO held by the OPTIONEE is exercised after the expiration
          of three (3) months after such TERMINATION, the exercise will be
          deemed to involve the exercise of a NON-QUALIFIED STOCK OPTION.

     (f)  In the event of a TERMINATION for any reason other than those
          specified in subparagraphs (a) through (e) above, (i) any unexercised
          OPTION or OPTIONS granted under the PROGRAM shall be deemed canceled
          and terminated forthwith, except that the OPTIONEE may exercise any
          unexercised OPTIONS theretofore granted which are otherwise
          exercisable and vested within the provisions of Section 11(a) hereof,
          during the balance of their respective terms or within thirty (30)
          days of such TERMINATION, whichever is shorter, and (ii) the DEA (if
          any) shall not be credited with any dividends paid after the date of
          such TERMINATION.

                                       20
<PAGE>

     (g)  Notwithstanding the provisions of subparagraphs (a) through (f) above,
          the COMMITTEE may, in its sole discretion, establish different terms
          and conditions pertaining to the effect of TERMINATION, to the extent
          permitted by applicable federal and state law.

13.  Payment for Shares Upon Exercise of Options
     -------------------------------------------

     The exercise of any OPTION shall be contingent upon receipt by the
     CORPORATION of (i) cash (including any DEA funds payable to the OPTIONEE in
     connection with the exercise of such OPTION), (ii) check, (iii) shares of
     COMMON STOCK, (iv) an executed exercise notice together with irrevocable
     instructions to a broker to either sell the shares subject to the OPTION or
     hold such shares as collateral for a margin loan and to promptly deliver to
     the CORPORATION the amount of sale or loan proceeds required to pay the
     OPTION PRICE, (v) any combination of the foregoing in an amount equal to
     the full OPTION PRICE of the shares being purchased, or (vi) such other
     consideration and method of payment, other than a note from the OPTIONEE,
     as the COMMITTEE, in its sole discretion, may allow (which, in the case of
     an ISO shall be determined at the time of grant), to the extent permitted
     by applicable law.  For purposes of this paragraph, shares of COMMON STOCK
     that are delivered in payment of the OPTION PRICE must have been previously
     owned by the OPTIONEE for a minimum of one year, and shall be valued at
     their FAIR MARKET VALUE as of the date of the exercise of the OPTION.  The
     CORPORATION shall not make loans to any OPTIONEE for the purpose of
     exercising OPTIONS.

14.  Adjustments Upon Changes in Number or Value of Shares of Common Stock
     ---------------------------------------------------------------------

     If there are any changes in the number or value of shares of COMMON STOCK
     by reason of stock dividends, stock splits, reverse stock splits,
     recapitalizations, mergers, consolidations or other events that materially
     increase or decrease the number or value of issued and outstanding shares
     of COMMON STOCK, the COMMITTEE may make such adjustments as it shall deem
     appropriate, in order to prevent dilution or enlargement of rights.

15.  Non-Transferability of Options
     ------------------------------

     An OPTION shall not be transferable by the OPTIONEE otherwise than by will
     or the laws of descent and distribution, or pursuant to a qualified
     domestic relations order as defined by the CODE, Title I of ERISA or the
     rules thereunder.  During the lifetime of the OPTIONEE, an OPTION may be
     exercised only by the OPTIONEE or by an alternate payee under a qualified
     domestic relations order.

16.  Change in Control
     -----------------

                                       21
<PAGE>

     Upon the occurrence of a CHANGE IN CONTROL (as defined below), any time
     periods relating to the exercise of any OPTION granted hereunder shall be
     accelerated so that such OPTION may be immediately exercised in full.

     A "CHANGE IN CONTROL" shall be deemed to have occurred if:

     (a)  any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
          the EXCHANGE ACT, but excluding any benefit plan for EMPLOYEES or any
          trustee, agent or other fiduciary for any such plan acting in such
          person's capacity as such fiduciary), directly or indirectly, becomes
          the beneficial owner of securities of PG&E CORPORATION representing
          twenty percent (20%) or more of the combined voting power of the
          CORPORATION's then outstanding securities;

     (b)  during any two consecutive years, individuals who at the beginning of
          such a period constitute the BOARD OF DIRECTORS cease for any reason
          to constitute at least a majority of the BOARD OF DIRECTORS, unless
          the election, or the nomination for election by the shareholders of
          the CORPORATION, of each new DIRECTOR was approved by a vote of at
          least two-thirds (2/3) of the DIRECTORS then still in office who were
          DIRECTORS at the beginning of the period; or

     (c)  the shareholders of the CORPORATION shall have approved (i) any
          consolidation or merger of the CORPORATION other than a merger or
          consolidation which would result in the voting securities of the
          CORPORATION outstanding immediately prior thereto continuing to
          represent (either by remaining outstanding or by being converted into
          voting securities of the surviving entity or any parent of such
          surviving entity) at least 70 percent of the Combined Voting Power of
          the CORPORATION, such surviving entity or the parent of such surviving
          entity outstanding immediately after the merger or consolidation; (ii)
          any sale, lease, exchange or other transfer (in one transaction or a
          series of related transactions) of all or substantially all of the
          assets of the CORPORATION, or (iii) any plan or proposal for the
          liquidation or dissolution of the CORPORATION.  For purposes of this
          paragraph, the term Combined Voting Power shall mean the combined
          voting power of the CORPORATION's or other relevant entity's then
          outstanding voting securities.

                                       22
<PAGE>

17.  Listing and Registration of Shares
     ----------------------------------

     Each OPTION shall be subject to the requirement that if at any time the
     COMMITTEE shall determine, in its discretion, that the listing,
     registration or qualification of the shares covered thereby under any
     securities exchange or under any state or federal law or the consent or
     approval of any governmental regulatory body, including the California
     Public Utilities Commission, is necessary or desirable as a condition of,
     or in connection with, the granting of such OPTION or the issue or purchase
     of shares thereunder, such OPTION may not be exercised in whole or in part
     unless and until such listing, registration, qualification, consent or
     approval shall have been effected or obtained free of any conditions not
     acceptable to the COMMITTEE.

18.  Amendment and Termination of the Plan and Options
     -------------------------------------------------

     The BOARD OF DIRECTORS or the COMMITTEE may at any time suspend, terminate,
     modify or amend the PLAN in any respect; provided, however, that, to the
     extent necessary and desirable to comply with Section 422 of the CODE (or
     any other applicable law or regulation, including the requirements of any
     stock exchange on which the COMMON STOCK is listed or quoted), shareholder
     approval of any PLAN amendment shall be obtained in such a manner and to
     such a degree as is required by the applicable law or regulation.

     No suspension, termination, modification or amendment of the PLAN may,
     without the consent of the OPTIONEE, adversely affect his or her rights
     under OPTIONS theretofore granted to such OPTIONEE.  In the event of
     amendments to the CODE or applicable rules or regulations relating to ISOS
     subsequent to the date hereof, the CORPORATION may amend the PLAN, and the
     CORPORATION and OPTIONEES holding OPTION agreements may agree to amend
     outstanding OPTION agreements, to conform to such amendments.

     The COMMITTEE may make such amendments or modifications in the terms and
     conditions of any OPTION as it may deem advisable, or cancel or annul any
     grant of an OPTION; provided, however, that no such amendment,
     modification, cancellation or annulment may, without the consent of the
     OPTIONEE, adversely affect his or her rights under such OPTION; and
     provided further the COMMITTEE may not reduce the OPTION PRICE or purchase
     price of any OPTION or OPTION below the original OPTION PRICE or purchase
     price.

     Notwithstanding the foregoing, the COMMITTEE reserves the right, in its
     sole discretion, to (i) convert any outstanding ISOS to NON-QUALIFIED STOCK
     OPTIONS, (ii) to require a OPTIONEE to forfeit any unexercised or
     unpurchased OPTIONS, any shares received or purchased pursuant to an
     OPTION, or any gains realized by virtue of the receipt of an OPTION in the
     event that such OPTIONEE competes against the CORPORATION, and (iii) to
     cancel or annul any grant of an

                                       23
<PAGE>

     OPTION in the event of a OPTIONEE'S TERMINATION FOR CAUSE. For purposes of
     the PROGRAM, "TERMINATION FOR CAUSE" shall include, but not be limited to,
     termination because of dishonesty, criminal offense or violation of a work
     rule, and shall be determined by, and in the sole discretion of, the
     COMMITTEE.

of the YEAR, the COMMITTEE reserves the right to modify or adjust a previously
set PERFORMANCE TARGET if, in its sole discretion, extraordinary events warrant
such modification or adjustment; provided, however, that no such modification or
adjustment shall increase the amount of any payment that would otherwise be due
based upon performance as measured against the original PERFORMANCE TARGET.

          2.03  Each grant of PUP UNITS shall have its own VESTING PERIOD.
Subject to modification as measured against a given YEAR's applicable
PERFORMANCE TARGET, each grant of PUP UNITS shall be payable as follows:

          a.  One-third after the end of the first YEAR of the VESTING PERIOD;

                                       29
<PAGE>

          b.  One-third after the end of the second YEAR of the VESTING PERIOD;
and

          c.  One-third after the end of the third YEAR of the VESTING PERIOD.

          2.04  To determine the number of PUP UNITS earned, the applicable
PERFORMANCE TARGET shall be the PERFORMANCE TARGET for the YEAR in which the PUP
UNITS vest.  Performance as measured against the applicable PERFORMANCE TARGET
for a YEAR shall modify all PUP UNITS that vest at the end of such YEAR.  The
PERFORMANCE TARGETS established by the COMMITTEE may modify the number of UNITS
earned from 0% to 200% of the number of vested UNITS.

          2.05  ELIGIBLE EMPLOYEES shall receive a cash payment as soon as
practicable following the YEAR PUP UNITS vest pursuant to the schedule set forth
in Section 2.03.  The amount of the payment shall be equal to the product of the
number of PUP UNITS earned multiplied by the PRICE of STOCK.

          2.06  Each time that the CORPORATION declares a dividend on its STOCK,
an amount equal to the dividend multiplied by an ELIGIBLE EMPLOYEE's
outstanding, but unearned PUP UNITS, shall be accrued on behalf of each ELIGIBLE
EMPLOYEE.  As soon as practicable following the end of each YEAR, ELIGIBLE
EMPLOYEES shall receive a cash payment of the dividends accrued for that YEAR,
modified by performance for that YEAR as measured under Section 2.04.

          2.07  An ELIGIBLE EMPLOYEE may elect to defer the payment of PUP UNITS
and/or dividends paid on PUP UNITS by making a timely election under the
Deferred Compensation Plan.  Deferrals of benefits payable under this Plan shall
be subject to the rules contained in the Deferred Compensation Plan governing
elections to defer and receipt of deferred amounts.


                                  ARTICLE III

          3.01  Retirement.  Upon RETIREMENT, all outstanding PUP UNITS continue
                ----------
to be payable according to the terms of the PLAN.  Thus, the number of UNITS
eventually earned by a retired employee is still subject to modification
depending on the extent to which applicable PERFORMANCE TARGETS are met during
the YEAR preceding the January in which UNITS become payable under the schedule
of Section 2.03.  A retired employee is not entitled to receive grants of PUP
UNITS after RETIREMENT.

          3.02  Disability.  If an ELIGIBLE EMPLOYEE is both disabled and
                ----------
entitled to receive benefits under Pacific Gas and Electric Company's Long Term

                                       30

Disability Plan, UNITS granted prior to the date of disability shall continue to
be payable according to the terms of this PLAN.  An ELIGIBLE EMPLOYEE is not
entitled to receive grants of PUP UNITS after the date of disability as
determined under the provisions of the Long Term Disability Plan.  If an
ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE EMPLOYEE because of disability and is
not entitled to receive benefits under Pacific Gas and Electric Company's Long
Term Disability Plan, all outstanding grants of PUP UNITS become vested and
payable as soon as practicable in the YEAR following the YEAR in which the
ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE EMPLOYEE.  All of the UNITS payable
shall be subject to modification based upon performance as measured against the
PERFORMANCE TARGET for the YEAR in which the ELIGIBLE EMPLOYEE ceases to be an
ELIGIBLE EMPLOYEE.

          3.03  Death.  In the event of the death of an ELIGIBLE EMPLOYEE, all
                -----
outstanding grants of PUP UNITS held by the ELIGIBLE EMPLOYEE at the date of
death shall become vested and payable as soon as practicable in the YEAR
following the YEAR of death.  All of the UNITS payable after an ELIGIBLE
EMPLOYEE's death shall be subject to modification based upon performance as
measured against the PERFORMANCE TARGET for the YEAR in which the death of the
ELIGIBLE EMPLOYEE occurs.

          3.04  Termination.  If an ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE
                -----------
EMPLOYEE for any reason other than RETIREMENT, disability, or death, all
outstanding grants of PUP UNITS shall be canceled as of the date that the
ELIGIBLE EMPLOYEE ceases to be an ELIGIBLE EMPLOYEE unless otherwise provided in
the PG&E Corporation Officer Severance Policy.

          3.05  Change in Control.  Upon a Change in Control as defined in the
                -----------------
PG&E Corporation Long Term Incentive Program (Program), all PUP UNITS shall
become vested and payable as soon as practicable in the YEAR following the
Change in Control in accordance with Section 16 of the Program.


                                  ARTICLE IV

                           ADMINISTRATIVE PROVISIONS
                           -------------------------

          4.01  Administration.  The PLAN shall be administered by the PLAN
                --------------
ADMINISTRATOR who shall have the authority to interpret the PLAN and make such
rules as it deems appropriate. The PLAN ADMINISTRATOR shall have the duty and
responsibility of maintaining records, making the requisite calculations, and
disbursing payments hereunder. The PLAN ADMINISTRATOR's interpretations,
determinations, rules, and calculations shall be final and binding on all
persons and parties concerned.

          4.02  Amendment and Termination.  The CORPORATION may amend or
                -------------------------
terminate the PLAN at any time, provided, however, that no such amendment or

                                       31
<PAGE>

termination shall adversely affect PUP UNITS which an ELIGIBLE EMPLOYEE has
earned prior to the date of such amendment or termination. PUP UNITS outstanding
but unearned at the date of any such amendment or termination may, in the sole
discretion of the CORPORATION, be canceled, and the CORPORATION shall have no
obligation to provide a substitute benefit of lesser, equal, or greater value.

          4.03  Nonassignability of Benefits.  The benefits payable under this
                ----------------------------
PLAN or the right to receive future benefits under this PLAN may not be
anticipated, alienated, pledged, encumbered, or subject to any charge or legal
process, and if any attempt is made to do so, or a person eligible for any
benefits becomes bankrupt, the interest under the PLAN of the person affected
may be terminated by the PLAN ADMINISTRATOR which, in its sole discretion, may
cause the same to be held if applied for the benefit of one or more of the
dependents of such person or make any other disposition of such benefits that it
deems appropriate.

          4.04  No Guarantee of Employment.  Nothing contained in this PLAN
                --------------------------
shall be construed as a contract of employment between the CORPORATION or the
ELIGIBLE EMPLOYEE, or as a right of the ELIGIBLE EMPLOYEE to be continued in the
employ of the CORPORATION, to remain as an officer of the CORPORATION, or as a
limitation on the right of the CORPORATION to discharge any of its employees,
with or without cause.

          4.05  Benefits Unfunded and Unsecured.  The benefits under this PLAN
                -------------------------------
are unfunded, and the interest under this PLAN of any ELIGIBLE EMPLOYEE and such
ELIGIBLE EMPLOYEE's right to receive a distribution of benefits under this PLAN
shall be an unsecured claim against the general assets of the CORPORATION.

          4.06  Applicable Law.  All questions pertaining to the construction,
                --------------
validity, and effect of the PLAN shall be determined in accordance with the laws

                   NON-EMPLOYEE DIRECTOR STOCK INCENTIVE PLAN
                  (As amended effective as of April 21, 1999)

1.   Purpose of the Plan
     -------------------

     This is the controlling and definitive statement of the PG&E Corporation

     objectives, and to increase their proprietary interest in the success of
     the CORPORATION. Inasmuch as the PLAN is designed to encourage financial
     performance and to improve the value of shareholders' investment in PG&E
     CORPORATION, the costs of the PLAN will be funded from corporate earnings.

     PHANTOM STOCK under the PLAN shall be automatic and non-discretionary, and
     shall be made strictly in accordance with the provisions contained herein.
     No person shall have any discretion to select which NON-EMPLOYEE DIRECTORS
     shall be granted DIRECTOR RESTRICTED STOCK, NON-QUALIFIED STOCK OPTIONS or
     PHANTOM STOCK. Further, no person shall have any discretion to determine
     the number of shares of DIRECTOR RESTRICTED STOCK awarded to a NON-EMPLOYEE
     DIRECTOR, and, except as otherwise provided in Section 4 with respect to a
     NON-EMPLOYEE DIRECTOR'S election to allocate formula awards between NON-
     QUALIFIED STOCK OPTIONS and PHANTOM STOCK, no person shall have any
     discretion to determine the number of shares underlying NON-QUALIFIED STOCK

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

     (a)  On the first business day of each calendar year beginning on
          January 1, 1998, during the duration of the PLAN, each person who is a
          NON-EMPLOYEE DIRECTOR on the first business day of the applicable
          calendar year shall receive a grant of DIRECTOR RESTRICTED STOCK in an
          amount to be determined in accordance with the formula set forth in

/4/Capitalized words are defined in Section 15 hereof.

                                       33
<PAGE>

          STOCK to be granted to each NON-EMPLOYEE DIRECTOR each calendar year
          shall be determined by (i) dividing ten thousand dollars ($10,000) by
          the FAIR MARKET VALUE of the COMMON STOCK on the first business day of
          the applicable calendar year, and (ii) rounding the resulting number
          down to the nearest whole share. No person shall receive more than one
          (1) grant of DIRECTOR RESTRICTED STOCK during any calendar year.

     (b)  Shares of DIRECTOR RESTRICTED STOCK shall vest cumulatively as
          follows: (i) twenty percent (20%) of such shares on the first
          anniversary of the date of grant; (ii) forty percent (40%) of such
          shares on the second anniversary of the date of grant; (iii) sixty
          percent (60%) of such shares on the third anniversary of the date of
          grant; (iv) eighty percent (80%) of such shares on the fourth
          anniversary of the date of grant; and (v) one hundred percent (100%)
          of such shares on the fifth anniversary of the date of grant. Shares
          of DIRECTOR RESTRICTED STOCK may not be resold or otherwise

          with the provisions of this Section 3(b).

4.   Annual Election to Receive Non-Qualified Stock Options and Phantom Stock
     ------------------------------------------------------------------------

     By June 30 of each calendar year during the term of the Plan, each person
     who is then a NON-EMPLOYEE DIRECTOR shall deliver to the Corporate
     Secretary a written election to receive either NON-QUALIFIED STOCK OPTIONS
     or PHANTOM STOCK, or both, with an aggregate value of $20,000, on the first
     business day of the following calendar year, provided the person continues
     to be a NON-EMPLOYEE DIRECTOR on the date the award would otherwise be
     made. A NON-EMPLOYEE DIRECTOR may allocate between NON-QUALIFIED STOCK
     OPTIONS and PHANTOM STOCK in minimum increments with a value equal to
     $5,000, as determined in accordance with Section 5 below with respect to
     NON-QUALIFIED STOCK OPTIONS, and Section 6 below, with respect to PHANTOM
     STOCK. All awards of NON-QUALIFIED STOCK OPTIONS and PHANTOM STOCK made to
     NON-EMPLOYEE DIRECTORS shall comply with Section 5 and Section 6 below,
     respectively. A NON-EMPLOYEE DIRECTOR who has failed to make a timely
     election or who became a NON-EMPLOYEE DIRECTOR after June 30 shall be
     awarded NON-QUALIFIED STOCK OPTIONS and PHANTOM STOCK, each with a value of
     $10,000 as determined in accordance with Section 5 and Section 6,
     respectively, provided that the NON-EMPLOYEE DIRECTOR continues to be a
     NON-EMPLOYEE DIRECTOR on the on the first business day of the following
     calendar year. Notwithstanding the foregoing, elections for calendar year

5.   Grant of Non-Qualified Stock Options to Non-Employee Directors
     --------------------------------------------------------------

     (a)  On the first business day of each calendar year beginning on January
          1, 1998, during the duration of the PLAN, each person who is then a
          NON-EMPLOYEE DIRECTOR and who has elected to receive an award of NON-
          QUALIFIED STOCK OPTIONS in accordance with Section 4, shall receive a
          grant of NON-QUALIFIED STOCK OPTIONS with an aggregate value equal to
          $5,000, $10,000, $15,000, or $20,000, as previously elected by the
          NON-EMPLOYEE DIRECTOR (or $10,000 in the case of a NON-EMPLOYEE
          DIRECTOR who has failed to make a timely election in accordance with
          Section 4 or who became a NON-EMPLOYEE DIRECTOR after June 30) (the
          "Elected Option Value"). The number of shares subject to the NON-
          QUALIFIED STOCK OPTIONS shall be determined by dividing the Elected
          Option Value by the value of a NON-QUALIFIED STOCK OPTION to purchase
          a single share of PG&E Corporation common stock as of the first
          business day of the applicable calendar year. The per stock option
          value shall be calculated in accordance with the Black-Scholes stock
          option valuation method using the average preceding November closing
          price of PG&E Corporation stock and reducing the per option value so
          calculated by twenty percent. The resulting number of NON-QUALIFIED
          STOCK OPTIONS shall be rounded down to the nearest whole share. No
          person shall receive more than one grant of NON-QUALIFIED STOCK
          OPTIONS during any calendar year.

     (b)  The OPTION PRICE of the COMMON STOCK subject under each NON-QUALIFIED
          STOCK OPTION shall be the FAIR MARKET VALUE of the COMMON STOCK on the
          date of grant. The exercise of any NON-QUALIFIED STOCK OPTION shall be
          contingent upon receipt by the CORPORATION of (i) cash, (ii) check,
          (iii) shares of COMMON STOCK, (iv) an executed exercise notice
          together with irrevocable instructions to a broker to either sell the
          shares subject to the NON-QUALIFIED STOCK OPTION or hold such shares
          as collateral for a margin loan and to promptly deliver to the
          CORPORATION the amount of sale or loan proceeds required to pay the
          OPTION PRICE, or (v) any combination of the foregoing in an amount
          equal to the full OPTION PRICE of the shares being purchased. For
          purposes of this paragraph, shares of COMMON STOCK that are delivered
          in payment of the OPTION PRICE must have been previously owned by the
          GRANTEE for a minimum of one year, and shall be valued at their FAIR
          MARKET VALUE as of the date of the exercise of the NON-QUALIFIED STOCK
          OPTION. The CORPORATION shall not make loans to any GRANTEE for the
          purpose of exercising NON-QUALIFIED STOCK OPTIONS.

     (c)  Each NON-QUALIFIED STOCK OPTION granted under the Plan shall become
          exercisable and vested cumulatively as follows: (i) up to thirty-

                                       35
<PAGE>

          three percent (33%) of the NON-QUALIFIED STOCK OPTION may be exercised
          on or after the second anniversary of the date of grant; (ii) up to
          sixty-six percent (66%) of the NON-QUALIFIED STOCK OPTION may be
          exercised on or after the third anniversary of the date of grant; and
          (iii) up to one hundred percent (100%) of the NON-QUALIFIED STOCK
          OPTION may be exercised on or after the fourth anniversary of the date
          of grant.

     (d)  The term of each NON-QUALIFIED STOCK OPTION shall be ten years and one
          day from the date of grant, subject to earlier termination as provided
          in Section 9 hereof. Any provision of the PLAN to the contrary
          notwithstanding, no NON-QUALIFIED STOCK OPTION shall be exercised
          after the time limitations stated in this Section 5(d).

6.   Awards of Phantom Stock to Non-Employee Directors
     -------------------------------------------------

     (a)  On the first business day of each calendar year beginning on January
          1, 1998, during the duration of the PLAN, each person who is then a
          NON-EMPLOYEE DIRECTOR and who has elected to receive an award of
          PHANTOM STOCK in accordance with Section 4, shall be credited with an
          amount of PHANTOM STOCK with a value (as determined by the FAIR MARKET
          VALUE of the COMMON STOCK on the first business day of the applicable
          calendar year) equal to $5,000, $10,000, $15,000, or $20,000, as
          previously elected by the NON-EMPLOYEE DIRECTOR (the "Elected Phantom
          Stock Value"). The number of shares of PHANTOM STOCK (including
          fractions computed to three decimal places) to be granted to each NON-
          EMPLOYEE DIRECTOR each calendar year shall be determined by dividing
          the Elected Phantom Stock Value (or $10,000 in the case of a NON-
          EMPLOYEE DIRECTOR who has failed to make a timely election in
          accordance with Section 4 or who became a NON-EMPLOYEE DIRECTOR after
          June 30) by the FAIR MARKET VALUE of the COMMON STOCK on the first
          business day of the applicable calendar year. No person shall receive
          more than one grant of PHANTOM STOCK during any calendar year. The
          shares of PHANTOM STOCK awarded to a NON-EMPLOYEE DIRECTOR shall be
          credited to a newly established PHANTOM STOCK account for the NON-
          EMPLOYEE DIRECTOR. Each share of PHANTOM STOCK shall be deemed to be
          equal to one share (or fraction thereof) of COMMON STOCK on the date
          of grant, and shall thereafter fluctuate in value in accordance with
          the FAIR MARKET VALUE of the COMMON STOCK.

     (b)  Each NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK account shall be credited
          quarterly on each dividend payment date with additional shares of
          PHANTOM STOCK (including fractions computed to three decimal places)
          determined by dividing (i) the aggregate amount of dividends, i.e,.
          the dividend multiplied by the number of shares of

                                       36
<PAGE>

          PHANTOM STOCK credited to the participant's account as of the dividend
          record date, by (ii) by the FAIR MARKET VALUE of the COMMON STOCK on
          the dividend payment date.

     (c)  Payment of the shares of PHANTOM STOCK credited to a NON-EMPLOYEE
          DIRECTOR'S PHANTOM STOCK account shall only be made after the NON-
          EMPLOYEE DIRECTOR'S RETIREMENT or MANDATORY RETIREMENT from the BOARD
          OF DIRECTORS. Payment shall be made only in the form of shares of
          COMMON STOCK equal to the number of shares of PHANTOM STOCK credited
          to the NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK account on the date of
          distribution, rounded down to the nearest whole share. The NON-
          EMPLOYEE DIRECTOR may elect to receive the number of shares of COMMON
          STOCK to which he is entitled in a lump sum distribution of the entire
          amount or in a series of ten or less approximately equal annual
          installments, provided that distribution shall commence no later than
          January of the year following the year in which the NON-EMPLOYEE
          DIRECTOR'S RETIREMENT or MANDATORY RETIREMENT occurred.

7.   Shares of Stock Subject to the Plan
     -----------------------------------

     There shall be reserved for use under the PLAN and for the grant of any
     other INCENTIVE AWARDS pursuant to the PROGRAM (subject to the provisions
     of Section 10 hereof) a total of 34,389,230 shares of COMMON STOCK, which
     shares may be authorized but unissued shares of COMMON STOCK or issued
     shares of COMMON STOCK which shall have been reacquired by PG&E
     CORPORATION.

8.   Dividend, Voting and Other Shareholder Rights
     ---------------------------------------------

     Except as otherwise provided in the PLAN, each GRANTEE shall have all of
     the rights of a shareholder of PG&E CORPORATION with respect to all
     outstanding shares of DIRECTOR RESTRICTED STOCK registered in his or her
     name, whether or not such shares are vested, including the right to receive
     dividends and other distributions paid or made with respect to such shares
     and the right to vote such shares. No GRANTEE shall have any of the rights
     of a shareholder of PG&E CORPORATION with respect to a NON-QUALIFIED STOCK
     OPTION until the shares acquired upon exercise of such NON-QUALIFIED STOCK
     OPTION have been issued and registered in his or her name. No GRANTEE shall
     have any of the rights of a shareholder of PG&E CORPORATION with respect to
     PHANTOM STOCK credited to the NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK account
     under the Plan.

          hereof, and the GRANTEE (or the GRANTEE'S estate or a person who
          acquired the shares of DIRECTOR RESTRICTED STOCK by bequest or
          inheritance) shall have the right to resell or transfer such shares at
          any time, (ii) all NON-QUALIFIED STOCK OPTIONS held by the GRANTEE, to
          the extent that such NON-QUALIFIED STOCK OPTIONS have not previously
          expired or been exercised, shall become fully vested and exercisable,
          notwithstanding the provisions of Section 5(c) hereof, and the GRANTEE
          (or the GRANTEE'S estate or a person who acquired the right to
          exercise the NON-QUALIFIED STOCK OPTION by bequest or inheritance)
          shall have the right to exercise the NON-QUALIFIED STOCK OPTIONS at
          any time within their respective terms or within one (1) year after
          the date of the GRANTEE'S death or disability, whichever is shorter,

          shares of PHANTOM STOCK by bequest or inheritance) in the form of a
          number of shares of COMMON STOCK equal to the number of shares of
          PHANTOM STOCK credited to the NON-EMPLOYEE DIRECTOR'S PHANTOM STOCK
          account, rounded down to the nearest whole share. The term

          Section 5(c) hereof, and the GRANTEE shall have the right to exercise

          be deemed to be canceled and no longer outstanding as of the date of
          TERMINATION; and from and after the date of TERMINATION, the GRANTEE

10.  Adjustments Upon Changes in Number or Value of Shares of Common Stock

     If there are any changes in the number or value of shares of COMMON STOCK
     by reason of stock dividends, stock splits, reverse stock splits,
     recapitalizations, mergers, consolidations or other events that materially
     increase or decrease the number or value of issued and outstanding shares
     of COMMON STOCK, the BOARD OF DIRECTORS or COMMITTEE may make such
     adjustments as it shall deem appropriate, in order to prevent dilution or
     enlargement of rights.

11.  Non-Transferability

     NON-QUALIFIED STOCK OPTIONS, PHANTOM STOCK, and shares of DIRECTOR
     RESTRICTED STOCK that have not vested in accordance with the provisions of
     Section 3(b) hereof, shall not be transferable by the GRANTEE otherwise
     than by will or the laws of descent and distribution, or pursuant to a

     Upon the occurrence of a CHANGE IN CONTROL (as defined below), (i) any time
     periods relating to the vesting of any shares of DIRECTOR RESTRICTED STOCK
     granted hereunder shall be accelerated so that all such shares immediately
     become fully vested, (ii) any time periods relating to the vesting of NON-
     QUALIFIED STOCK OPTIONS granted hereunder shall be accelerated so that all
     such NON-QUALIFIED STOCK OPTIONS immediately become fully vested and

     PHANTOM STOCK credited to the NON-EMPLOYEE DIRECTORS' PHANTOM STOCK
     accounts shall become payable in accordance with Section 6(c) hereof as if
     the CHANGE IN CONTROL constituted a RETIREMENT.

     A "CHANGE IN CONTROL" shall be deemed to have occurred if:

     (a)  any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
          the EXCHANGE ACT, but excluding any benefit plan for EMPLOYEES or any
          trustee, agent or other fiduciary for any such plan acting in such
          person's capacity as such fiduciary), directly or indirectly, becomes
          the beneficial owner of securities of PG&E CORPORATION representing
          twenty percent (20%) or more of the combined voting power of PG&E
          CORPORATION's then outstanding securities;

     (b)  during any two consecutive years, individuals who at the beginning of
          such a period constitute the BOARD OF DIRECTORS cease for any reason
          to constitute at least a majority of the BOARD OF DIRECTORS, unless
          the election, or the nomination for election by the shareholders of
          PG&E CORPORATION, of each new DIRECTOR was approved by a vote of at
          least two-thirds (2/3) of the DIRECTORS then still in office who were
          DIRECTORS at the beginning of the period; or

     the shareholders of the CORPORATION shall have approved (i) any
     consolidation or merger of the CORPORATION other than a merger or
     consolidation which would result in the voting securities of the
     CORPORATION outstanding immediately prior thereto continuing to represent
     (either by remaining outstanding or by being converted into voting
     securities of the surviving entity or any parent of such surviving entity)
     at least 70 percent of the Combined Voting Power of the CORPORATION, such
     surviving entity or the parent of such surviving entity outstanding
     immediately after the merger or consolidation; (ii) any sale, lease,
     exchange or other transfer (in one transaction or a series of related
     transactions) of all or substantially all of the assets of the CORPORATION,
     or (iii) any plan or proposal for the liquidation or dissolution of the
     CORPORATION.  For purposes of this paragraph, the term Combined Voting
     Power shall mean the combined voting power of the CORPORATION's or other
     relevant entity's then outstanding voting securities.

     The BOARD OF DIRECTORS or the COMMITTEE may at any time suspend, terminate,
     modify or amend the PLAN in any respect; provided, however, that, to the
     extent necessary and desirable to comply with the CODE (or any other
     applicable law or regulation, including the requirements of any stock
     exchange on which the COMMON STOCK is listed or quoted), shareholder
     approval of any PLAN amendment shall be obtained in such a manner and to
     such a degree as is required by the applicable law or regulation.

     No suspension, termination, modification or amendment of the PLAN may,
     without the consent of the GRANTEE, adversely affect his or her rights with
     respect to DIRECTOR RESTRICTED STOCK, NON-QUALIFIED STOCK OPTIONS or
     PHANTOM STOCK theretofore granted to such GRANTEE.

     Except as provided in Section 2 hereof, the BOARD OF DIRECTORS or COMMITTEE
     may make such amendments or modifications in the terms and conditions of
     any grant of DIRECTOR RESTRICTED STOCK, NON-QUALIFIED STOCK OPTIONS or
     PHANTOM STOCK as it may deem advisable, or cancel or annul any grant of
     DIRECTOR RESTRICTED STOCK, NON-QUALIFIED STOCK OPTIONS or PHANTOM STOCK;
     provided, however, that no such amendment, modification, cancellation or
     annulment may, without the consent of the GRANTEE, adversely affect his or
     her rights with respect to such grant.
