C.   Plan Purpose and General Description

     1.   The main purposes of the Plan are:

          a.   To motivate Participants to develop and
               successfully execute those sustained performance
               objectives which will assure the continuous
               delivery of reliable energy to customers at a
               competitive price, and maximize the Company's
               prospects for achieving a sustainable competitive
               return for its shareholders over the long term.

          b.   To focus Participants on key annual goals
               representing progress toward longer term
               strategic objectives.

          c.   To recognize and reward superior performance on
               both an individual and a team basis.

          d.   To help retain and attract superior talent at the
               senior executive level and to do so with pay-for-
               performance, variable cost incentive award
               dollars where the level of award is linked to
               sustained successful Participant performance,
               Company performance and the returns to the
               Company's shareholders.

     2.   Personal Performance shall be evaluated each fiscal
          year.  Awards and other opportunities otherwise
          applicable under this Plan shall be reduced or
          eliminated for any Participant if his or her Personal
          Performance is less than the level expected for a key
          employee of the Company.

     3.   Exhibit A provides an overview of the Plan in
          operation.

     4.   Performance goals shall be established by the
          Committee for the Plan each fiscal year and shall
          focus on a few very key results.  These goals shall be
          set forth on an Exhibit B each year, which shall be
          amended by the Committee from time to time, as
          appropriate.  Performance in areas not set forth in
          such Exhibit B can also be recognized by the Committee
          on a subjective basis each year.

     5.   A Trigger, as detailed in F. below, shall be
          established each fiscal year.  Awards and other
          opportunities otherwise applicable shall be reduced or
          eliminated unless the related corporate performance
          threshold(s), as set forth in the Trigger, are
          satisfied.

     6.   Awards earned for each fiscal year, if any, shall be
          credited to individually maintained Participant
          Accounts.  Beginning April 1, 1995 the dollar value of
          such Accounts shall fluctuate up or down each year (as
          reflected by the Value Change Percentage) - based on
          Company and Personal Performance and shareholder
          returns.

     7.   Each Participant shall receive a Payout of a portion
          of the dollar value of his or her Participant Account
          on the first two of every three Award Dates beginning
          on April 1, 1996.  Payouts shall be in cash.

     8.   In the event of a Participant's death, Total
          Disability, Retirement, or Qualifying Termination, the
          then dollar value of such Participant's Account shall
          become immediately vested and shall then be paid out
          in cash to the Participant or his or her beneficiary
          as designated by the Plan.  For the fiscal year in
          which such an event occurs, the Participant's Annual
          Award shall be paid in cash and prorated for the
          period of participation up to the date of death, Total
          Disability, Retirement, or Qualifying Termination.

     9.   In the event a Participant's employment with the
          Company terminates for any reason other than death,
          Total Disability, Retirement, or Qualifying
          Termination, such Participant shall forfeit the entire
          amount of his or her Participant Account as in effect
          at such termination.  In addition, such a termination
          occurring before Annual Awards are actually credited
          for any fiscal years performance shall result in the
          total and complete forfeiture of such Participant's
          right in any such Annual Awards credited for such
          fiscal year.


D.   Participation in the SPP

     1.   Participation in the SPP shall be limited to key
          employees so designated on an Exhibit C as
          Participants by the Committee each fiscal year.

     2.   Participation in one fiscal year does not guarantee
          participation in any subsequent year.  Should a former
          Participant be judged by the Committee to be
          ineligible for continued participation and is so
          informed in writing by the Company, such Participant
          shall immediately cease to be eligible for any
          subsequent Annual Award, and shall also immediately
          surrender all rights to his or her Participant Account
          in exchange for three annual payments equal to one-
          third of the dollar value of such Account as of the
          date of the notice of non-participation sent by the
          Company plus interest at a rate determined by the
          Company for the second and third installments.  At the
          Company's sole option, such payments may be made in a
          single lump sum.

     3.   Prorata participation during a fiscal year may be
          authorized by the Committee.

E.   Incentive Opportunity

     1.   Incentive opportunity consists of three distinct
          items:

          a.   Annual Awards;

          b.   Dollar value enhancement for Participant
               Accounts; and

          c.   Dollar gains realized due to the appreciation in
               Stock price as utilized in the Payout
               calculation.

     2.   Annual Award opportunity shall be expressed as a
          percentage of each Participant's annual salary rate as
          in effect at the end of the fiscal year for which
          performance was measured.  The Annual Award
          opportunity shall be set forth on an Exhibit C each
          year, as amended.

F.   Trigger Element

     1.   Each fiscal year the Committee shall establish a
          Trigger element for the Plan.  The Trigger shall be
          set forth on an Exhibit D each year, as amended.

     2.   This Trigger shall consist of a specified base level
          of financial or other performance which must be
          satisfied if the full, otherwise generated, Annual
          Award opportunity under the Plan is to be realized by
          the Participants.

G.   Determining Annual Awards

     1.   Annual Awards shall be determined by the Committee as
          of each Award Date.

     2.   This determination shall be a two-step process using a
          "100 point system" as described below: 

          a.   Formal Award:  The Committee shall award from 0 -
               100 points on the basis of actual, demonstrated
               Company performance against the specific
               performance goals established for the fiscal year
               to which such awards relate.

          b.   Discretionary Award:  The Committee may also
               award from 0 - 30 points on a discretionary basis
               to recognize and reward other outstanding
               performance results not, in the Committee's sole
               judgment, adequately recognized or rewarded by
               the Formal Award above.

          c.   The two point awards shall then be added together
               and the sum, not to exceed 100, used in
               conjunction with this Annual Award table:


               If Total Points   Annual Award   Annual Awards As
                Awarded Are:       Level Is:     % Salary Are:

                less than 35         None              0
                     35         Threshold Level    As Set By
                     70          Target Level    Committee For
                    100          Maximum Level    Fiscal Year

               Annual Awards prorated for results between
               Threshold and Target or Target and Maximum

          d.   Exhibit E sets forth the specific performance
               goals, and examples of total point awards and the
               resulting percentage of salary Annual Awards set
               for the current fiscal year for a hypothetical
               participant.

          e.   Once determined, Annual Awards, if any, shall be
               credited to Participant Accounts each year as of
               the Award Date.

H.   Value Changes for Participant Accounts

     1.   The dollar value of all Participant Accounts shall be
          adjusted in an identical manner as of each Award Date
          beginning April 1, 1995.

     2.   This adjustment shall be from a 20% loss to a 30% gain
          with such adjustment being applicable to:

          a.   the full dollar value of each Participant Account
               prior to any Payout due on such Award Date; but

          b.   excluding the Annual Award, if any, being
               credited to each Participant Account on such
               Award Date.

     3.   The adjustment in dollar value shall be based upon the
          Value Change Percentage determined as set forth in (4)
          below.

     4.   The Value Change Percentage shall be set by the
          Committee for each Award Date based on this two step
          process:

          a.   First, the total points already established for
               the Annual Awards for such Award Date shall be
               applied to this table to determine a Value Change
               Percentage:

               Points Used For Annual Awards      Value Change

                      less than 35                 Minus 10%
                           35                       Plus 5%
                           70                       Plus 10%
                          100                       Plus 20%

               Prorate Percentage for points between 35 and 70
               or 70 and 100

          b.   Second, the Percentage from the above table shall
               be increased or reduced by up to ten percentage
               points by comparing the Total Return to the
               Company's Shareholders for the prior fiscal year
               to the Median Total Return for all Utility
               Companies included in the Solomon Brothers
               Utility Group for the period to which the value
               change relates.  A percentage increase shall be
               used if the Total Return to Company Shareholders
               is higher than such Median, and a decrease if
               lower.

          c.   The following is an example of this two step
               process in operation:


 Points   First Step   Company Stock     Median        Final
 Earned   Percentage   Total Return   Total Return   Percentage

   30       (10%)           6.0%          8.0%         (12%)
   35         5%            8.0%          8.0%           5%
   70        10%           10.0%          8.0%          12%
   85        15%           12.0%          8.0%          19%
  100        20%           19.0%          8.0%        30% (max)

     5.   Should the Annual Awards to which Participants would
          otherwise be entitled on a given award date be reduced
          or eliminated as a result of the operation of the
          Trigger Element, the Committee may, at its discretion,
          modify the Value Change Percentage.

I.   Payouts - Active Participants

     1.   No Payouts shall occur prior to April 1, 1996.

     2.   Subject to the Trigger, periodic Payouts shall be made
          on the first two out of every three Award Dates on and
          after April 1, 1996.

     3.   Effective April 1, 1996 and every third year
          thereafter (April 1, 1999, April 1, 2002, etc.), each
          Participant shall receive a cash payment equal to two-
          thirds of the dollar value of his or her Participant
          Account with such dollar value being equal to:

          a.   The dollar value of the Account from the prior
               Award Date increased or reduced by the Value
               Change Percentage applied for the current Award
               Date; plus

          b.   The Annual Award credited to the Participant
               Account as of the current Award Date.

     4.   Effective April 1, 1997 and every three years
          thereafter (April 1, 2000, April 1, 2003, etc.), each
          Participant shall receive a payment in cash equal to:

          a.   One-half of the dollar value of his or her
               Participant Account with such "dollar value"
               determined as set forth in (3)(a) and (b) above;
               divided by

          b.   $22.13 (Stock price on 12/31/92); and

          c.   Multiplied by the Stock price as of the close of
               business on the March 15 immediately preceding
               the Award Date.

     5.   The following is an example of this calculation if the
          Stock price referred to in 4.c. above is $25.00:
          Dollar Value   One-Half    Divided by   Multiplied by
           of Account    of This       $22.13         $25.00
 
            $20,000      $10,000       451.88        $11,297
            $46,004      $23,002     1,039.40        $25,985

     6.   The actual dollar value of this payment will be more
          than one-half of the dollar value of the Participant
          Account if the actual market value of Company Stock is
          over $22.13, and less than such amount if the Stock
          price is under $22.13.

     7.   Exhibit F is a sample Participant Account illustrating
          both Payouts.

J.   Personal Performance

     1.   The CEO shall evaluate the Personal Performance of
          every Participant, other than himself (or herself),
          each fiscal year, and the Committee shall do the same
          for the CEO.  The evaluations of performance made by
          the CEO shall be reviewed with the Committee.

     2.   Should the Personal Performance of any Participant be
          less than that expected from a key employee, the
          Committee (acting on a recommendation from the CEO in
          respect to any Participant other than the CEO) may,
          not withstanding any other provision of the Plan,
          eliminate or reduce any Annual Award otherwise
          payable.

K.   Performance Goals and Unusual Events

     1.   Specific performance goals established for any fiscal
          year shall not normally be altered or otherwise
          adjusted.  However, in the event of highly unusual
          circumstances or significant events which render
          established goals totally inconsistent with the
          purposes an intents of the Plan, the Committee may
          adjust such goals during a fiscal year.

L.   Miscellaneous and Administrative Provisions

     1.   All calculated amounts under the Plan shall be rounded
          to the next higher whole dollar amount.

     2.   All Payouts shall be subject to all applicable
          Federal, State, and local taxation and shall be
          subject to all applicable withholding for such
          taxation.

     3.   Payouts shall not count as "compensation" for the
          purpose of any benefit plan of the Company including
          the Supplemental Retirement Plan.

     4.   Voluntary, irrevocable deferral of any or all Payouts
          may be elected by Participants on terms approved by
          the Committee.

     5.   Participation in the SPP does not guarantee employment
          rights to any employee, and participation in the SPP
          in one fiscal year does not automatically result in
          participation in any subsequent year.

     6.   Each Participant shall be required to provide the
          Company with a written beneficiary designation for
          Plan purposes, and maintaining such designation shall
          be the sole responsibility of the Participant.  In the
          event the beneficiary of record does not survive the
          Participant, any payments otherwise due shall be made
          to the Participant's estate.

     7.   The Company shall establish appropriate accounting
          reserves to recognize the liability of Annual Awards
          and periodic Payouts under the Plan.
