                     Vesting; Account Balance Allocation

3.1    Vesting in Change in Control Benefit.

       (a)    General  Rule.    If  a  Participant has  not  Retired,  died,
              suffered  a   Disability  or  experienced  a   Termination  of
              Employment prior to  90 days prior to a Change in Control, the
              Participant shall become 100%  vested in his or her  Change in
              Control Benefit  on January 1 of  the Plan Year  following the
              Change in  Control  (the "Vesting  Date"); provided,  however,
              that  if  a  Participant  voluntarily terminates  his  or  her
              employment with all Employers at any time on or after the date
              of  the Change in Control and prior  to the Vesting Date, that
              Participant shall forfeit his or her  rights to benefits under
              this Plan.

       (b)    Early Vesting.  If at any time on or  after 90 days prior to a
              Change  in Control and prior to the Vesting Date a Participant
              Retires,  dies,   suffers  a  Disability   or  experiences  an
              involuntarily  termination of  employment with  all Employers,
              the Participant (or the Participant's Beneficiary in the event
              of the Participant's death) shall become 100% vested in his or
              her Change in Control Benefit on the later of (i)  the date of
              the Change in  Control or  (ii) the date  of such  Retirement,
              death,  Disability or  involuntary termination  of employment,
              and such  date (rather  than January 1  of the following  Plan
              Year) shall be  considered the "Vesting Date"  for purposes of
              this Plan.

3.2    Account Balance Allocations.  Within 60  days of the end of each Plan
       Year, each Participant  with a  balance in his  or her  Participant's
       Account shall receive a statement of the dollar amount of  his or her
       balance.

                                  Benefits

4.1    Change in Control Benefit.

       (a)    Eligibility.    On the  Vesting Date,  the Participant  or the
              Participant's  Beneficiary shall become entitled to the Change
              in Control Benefit described in this Section 4.1.

       (b)    Benefit and Payment.  The "Change in Control Benefit" shall be
              a dollar  amount that is equal to the fair market value of the
              assets allocated  to and held in the  Participant's Account as
              of  the Vesting  Date,  plus any  earnings  allocated to  that
              account from that date to the date of payment of the Change in
              Control  Benefit.    This   benefit  shall  be  paid   to  the
              Participant,  or his or her Beneficiary, within 90 days of the
              Vesting Date.

4.2    Employer Benefit.

       (a)    Eligibility.  The Participant's  Employer shall be entitled to
              the Employer Benefit if:

                  (i)       A Participant Retires,  suffers a Disability  or
                            experiences a Termination of Employment prior to
                            90 days prior to a Change in Control;

                 (ii)       A Participant voluntarily  terminates his or her
                            employment   (other   than   by  Retirement   or
                            Disability) with all of  his or her Employers at
                            any time on  or after  the date of  a Change  in
                            Control and prior to January  1 of the Plan Year
                            following a Change in Control; or

                (iii)       A Participant dies at any time.

       (b)    Benefit  and  Payment.   The  "Employer  Benefit"  shall be  a
              distribution of  the  assets  allocated  to and  held  in  the
              Participant's Account as of the date of the event described in
              Section 4.2(a) above after taking in account any distributions
              made or to be made in accordance  with Section 4.1 above, plus
              any earnings allocated to  that account from that date  to the
              date of payment of  the Employer Benefit.  This  benefit shall
              be  paid to  the  Participant's Employer  within  120 days  of
              January 1 of the Plan Year following that event.

4.3    Withholding and Payroll Taxes.   The Trustee shall withhold  from any
       and  all benefit  payments made  under  this Article 4,  all federal,
       state and local  income, employment  and other taxes  required to  be
       withheld in  connection with  the payment  of benefits  hereunder, in
       amounts to  be  determined in  sole discretion  of the  Participant's
       Employer.


                                  ARTICLE 5
                                 Beneficiary

5.1    Beneficiary. Each Participant shall  have the right, at any  time, to
       designate his or her Beneficiary (both primary as well as contingent)
       to  receive any benefits payable under the Plan to a Beneficiary upon
       the death of a Participant.

5.2    Beneficiary Designation;  Change;  Spousal Consent.    A  Participant
       shall  designate his or her Beneficiary by completing and signing the
       Beneficiary Designation  Form, and returning  it to the  Committee or
       its designated agent.  A Participant shall have the right to change a
       Beneficiary by  completing, signing and otherwise  complying with the
       terms of the  Beneficiary Designation Form and  the Committee's rules
       and procedures, as in effect  from time to time.  If  the Participant
       names, with respect to more than 50% of his or her benefit under this
       Plan,  someone other  than  his or  her  spouse as  a  Beneficiary, a
       spousal consent, in  the form  designated by the  Committee, must  be
       signed by that  Participant's spouse and  returned to the  Committee.
       Upon the acceptance by the Committee of a new Beneficiary Designation
       Form,  all  Beneficiary   designations  previously  filed  shall   be
       cancelled.   The  Committee shall  be  entitled to  rely on  the last
       Beneficiary Designation Form filed by the Participant and accepted by
       the Committee before his or her death.

5.3    Acknowledgment.   No  designation  or  change  in  designation  of  a
       Beneficiary   shall  be   effective  until  received,   accepted  and
       acknowledged in writing by the Committee or its designated agent.

5.4    No  Beneficiary Designation.  If  a Participant fails  to designate a
       Beneficiary as provided in Sections 5.1, 5.2 and 5.3 above or, if all
       designated Beneficiaries  predecease the Participant or  die prior to
       complete  distribution  of  the   Participant's  benefits,  then  the
       Participant's designated Beneficiary shall be deemed to be his or her
       surviving  spouse.  If the  Participant has no  surviving spouse, the
       benefits remaining under  the Plan to be paid to  a Beneficiary shall
       be  payable  to  the  executor  or  personal  representative  of  the
       Participant's estate.

5.5    Doubt as to  Beneficiary.  If the Committee  has any doubt as  to the
       proper Beneficiary  to receive  payments pursuant  to this  Plan, the
       Committee shall have the right, exercisable in its discretion, before
       a  Change in Control, to cause  the Trustee to withhold such payments
       until this matter is resolved to the Committee's satisfaction.

5.6    Discharge of Obligations.   The payment of benefits under the Plan to
       a Beneficiary shall fully and completely discharge all  Employers and
       the Committee  from  all further  obligations  under this  Plan  with
       respect  to the  Participant, and  that Participant's  Plan Agreement
       shall terminate upon such full payment of benefits.

                          Termination, Amendment or
                          Modification of the Plan

6.1    Termination,  Amendment  or Modification  Prior  to  One Year  Before
       Change in Control.   Prior to  one year before  a Change in  Control,
       each Employer reserves the right to terminate the Plan or any related
       Plan Agreement, in  whole or  in part, with  respect to  Participants
       whose  services  are retained  by  that  Employer,  and  the  Company
       reserves the right to amended or  modify the Plan or any related Plan
       Agreement, in whole  or in  part, with respect  to all  Participants.
       Notwithstanding   the   foregoing,  no   termination,   amendment  or
       modification shall be effective to decrease or reduce a Participant's
       potential benefits under this Plan below the fair market value of the
       assets in his or her  Participant's Account as reflected on  the last
       statement provided  under Section 3.2  above prior  to the  effective
       date of the termination, amendment or modification.

6.2    Termination, Amendment or Modification  Within One Year Before Change
       of Control or Following Change in Control.

       (a)    General.    Within one  year before  a  Change in  Control and
              thereafter, neither the Company, any subsidiary of the Company
              nor any corporation,  trust or other  person that succeeds  to
              all  or any substantial portion  of the assets  of the Company
              shall  have the right to  terminate, amend or  modify the Plan
              and/or  any Plan Agreement in  effect prior to  such Change in
              Control, and all  benefits under  the Plan and  any such  Plan
              Agreement  shall thereafter  be  paid in  accordance with  the
              terms  of the  Plan  and such  Plan  Agreement, as  in  effect
              immediately prior to such  Change in Control.  If  the Plan is
              terminated, amended,  or modified  within one year  before the
              Change in Control, such termination, amendment or modification
              shall  be considered void as  of the date  of the termination,
              amendment or modification.   Subject to Section 6.2(b)  below,
              any  provision of  this  Plan or  any  Plan Agreement  to  the
              contrary  shall   be   construed  in   accordance  with   this
              Section 6.2(a).

       (b)    Compliance  with ERISA  and Code.   Notwithstanding  any other
              provision of this Plan, if, at any time within one year before
              a Change in  Control or  any time thereafter,  counsel to  the
              Company advises  the Company in  writing that it  is counsel's
              opinion  that the provisions  of this Plan  and/or any related
              Plan Agreement are not  in compliance with ERISA or  the Code,
              or any final or  proposed regulation or ruling under  ERISA or
              the  Code promulgated by  the Internal Revenue  Service or the
              Department  of Labor, the Company shall have the right, in its
              sole  discretion,  to amend,  modify  or  terminate this  Plan
              and/or any related Plan Agreement in order to comply with such
              applicable law, to minimize the Plan's noncompliance with such
              applicable law and/or to avoid the Plan from failing to comply
              with such applicable law.

       (c)    Limitation.    If  the  Company elects  to  amend,  modify  or
              terminate   the   Plan  and/or   any   Plan   Agreement  under
              Section 6.2(b),  the Company may do so only to the extent that
              such amendment, modification or termination does  not decrease
              or reduce  a Participant's  potential benefit under  this Plan
              below  the  fair market  value of  the  assets in  his  or her
              Participant's  Account  as  reflected on  the  last  statement
              provided under Section 3.2  above prior to the  effective date
              of the termination, amendment or modification.

6.3    Termination  of  Plan Agreement.    Absent  the earlier  termination,
       modification  or amendment  of the  Plan, the  Plan Agreement  of any
       Participant shall terminate upon the  full payment of the  applicable
       benefit provided under Article 4.

                        Other Benefits and Agreements

7.1    Coordination with  Other  Benefits.   The  benefits  provided  for  a
       Participant  and  Participant's Beneficiary  under  the  Plan are  in
       addition  to any other  benefits available to  such Participant under
       any  other  plan  or  program  for  employees  or  directors  of  the
       Participant's Employer.   The  Plan shall  supplement  and shall  not
       supersede, modify or  amend any other such plan  or program except as
       may otherwise be expressly provided.

       The benefit,  if any, to be received under this Plan shall be offset,
       but not below zero, by  the benefits that a Participant has  received
       in  the  past  as  a  "Short-Term  Payout"  or  as  a  result  of  an
       "Unforeseeable Financial Emergency"  under the Pinnacle  West Capital
       Corporation,  Arizona  Public  Service  Company,  Suncor  Development
       Company and  El Dorado Investment Company  1992 Deferred Compensation
       Plan, which was effective January 1, 1992.

                                    Trust

8.1    Establishment of the Trust; Premiums.  The  Employers shall establish
       the Trust and shall at least annually transfer over to the Trust such
       assets  as the Committee determines, prior to a Change in Control, or
       the Trustee determines, after  a Change in Control, are  necessary to
       provide for the Employers' future liabilities created with respect to
       the  benefits  provided  under  the  Plan  and  the Plan  Agreements,
       including, without  limitation, the payment of  insurance premiums in
       amounts sufficient to acquire  and maintain all Policies held  by the
       Trustee.   At the direction  of the Committee,  prior to a  Change in
       Control, or the  Trustee, after  a Change in  Control, the  Employers
       shall pay any and all Policy premiums and other costs directly to the
       Insurer.   In addition,  if the Trust  incurs any  tax liability, the
       Employers, to  the extent the administrative  account is insufficient
       to  pay such taxes, shall contribute to the Trust sufficient funds to
       allow the Trustee to pay any such tax liability.

8.2    Interrelationship of the Plan  and the Trust.  The provisions  of the
       Plan and the Plan Agreement shall govern the rights  of a Participant
       and the Employers to receive distributions pursuant to the Plan.  The
       provisions  of  the Trust  shall govern  the  rights of  the Trustee,
       Employers,  Participant and  a  Participant's Beneficiary  as to  the
       assets of  the Trust.  The Employers shall at all times remain liable
       to carry out their obligations under the Plan.  The Employers and the
       Trustee shall cooperate with  each other as is necessary  to minimize
       the Trust's tax liability.

8.3    Accounts.

       (a)    The  Trustee   shall  establish  and  maintain  the  following
              separate accounts in the Trust:

              (i)    A "Participant's Account" for each Participant to which
                     the Employers' contributions, or a portion thereof, and
                     earnings thereon  shall  be  allocated  to,  held,  and
                     invested, the assets of which are to be used to pay the
                     Change in  Control Benefit  and/or Employer  Benefit in
                     accordance with this Plan and the Trust; and
              (ii)   An  "Administrative  Account"  for  the  administrative
                     expenses  of  the  Trust  to which  a  portion  of  the
                     Employers'  contributions and  earnings thereon  may be
                     allocated to,  held and  invested, the assets  of which
                     are  to be  used  to pay  the administrative  expenses,
                     including all  taxes, of  the Trust in  accordance with
                     the terms and provisions of this Plan and the Trust.

       (b)    Prior to a Change  in Control, the Committee shall  direct the
              Trustee  in writing as to (i) the allocation of the Employers'
              contributions  to  the  accounts described  in  Section 8.3(a)
              above,  and  (ii) the  allocations  of  the  earnings  on  the
              Employer's  contributions held  and invested  in the  accounts
              described  in Section 8.3(a)  above.  Thereafter,  the Trustee
              shall make such  allocations in accordance with  the terms and
              provisions of this Plan and the Trust.

       (c)    Each of the  accounts described in Section 8.3(a)  above shall
              qualify  for  and be  treated  as separate  shares  under Code
              Section 663(c).

                             Insurance Policies

9.1    Policies.  The Committee may direct the Trustee in writing to acquire
       one or more Policies in the Trustee's name.  The Trustee shall be the
       sole  and absolute  owner and  beneficiary of  each Policy,  with all
       rights of an owner and beneficiary, including without limitation, the
       right  to surrender Policies for  their cash surrender  values and to
       take one or more loans against one or more Policies.  Notwithstanding
       the  foregoing, the  Trustee shall  exercise its ownership  rights in
       each Policy  only in  accordance with  the terms  of  this Plan,  the
       respective Plan Agreements and the Trust.

9.2    Documents  Required  By  Insurer.   The  Trustee,  the  Participant's
       Employer  and the Participant shall  sign such documents and provided
       such information as may be required from time to time by the Insurer.

       Plan.

10.4   Indemnity  of  Committee.   All  Employers shall  indemnify  and hold
       harmless the members  of the  Committee against any  and all  claims,
       losses, damages, expenses or liabilities  arising from any action  or

                              Claims Procedures

11.1   Presentation  of Claim.  Any Participant or Beneficiary of a deceased
       Participant (such Participant or  Beneficiary being referred to below
       as a "Claimant") may deliver  to the Committee a written claim  for a

       claim  within a  reasonable time,  and shall  notify the  Claimant in
       writing:

       (a)    that the Claimant's requested determination has been made, and
              that the claim has been allowed in full; or

       (b)    that the Committee has reached a conclusion contrary, in whole
              or  in part,  to the  Claimant's requested  determination, and
              such  notice must  set  forth in  a  manner calculated  to  be
              understood by the Claimant:

                  (i)       the specific  reason(s) for  the  denial of  the
                            claim, or any part of it;

                 (ii)       the    specific   reference(s)    to   pertinent
                            provisions of  the Plan  upon which  such denial
                            was based;

                (iii)       a  description of  any  additional  material  or
                            information  necessary  for   the  Claimant   to
                            perfect  the claim,  and an  explanation  of why
                            such material or information is necessary; and

                 (iv)       an explanation of the claim review procedure set
                            forth in Section 11.3 below.

11.3   Review of a  Denied Claim.  Within  60 days after receiving a  notice
       from the Committee that a claim has been denied, in whole or in part,
       a  Claimant (or  the Claimant's  duly authorized  representative) may
       file with  the Committee a written request for a review of the denial
       of  the claim.   Thereafter,  but not  later than  30 days  after the
       review  procedure  began,  the   Claimant  (or  the  Claimant's  duly
       authorized representative):

       (a)    may review pertinent documents;

       (b)    may submit written comments or other documents; and/or

       (c)    may  request  a hearing,  which  the  Committee, in  its  sole
              discretion, may grant.

11.4   Decision  on  Review.   The Committee  shall  render its  decision on
       review promptly, and  not later  than 60 days after  the filing of  a
       written request for review of the denial, unless a hearing is held or
       other special  circumstances require  additional time, in  which case
       the  Committee's decision must be rendered within 120 days after such
       date.  Such  decision must be  written in a  manner calculated to  be
       understood by the Claimant, and it must contain:

       (a)    specific reasons for the decision;

       (b)    specific reference(s) to  the pertinent  Plan provisions  upon
              which the decision was based; and

       (c)    such other matters as the Committee deems relevant.

11.5   Legal Action.  A Claimant's  compliance with the foregoing provisions
       of  this Article 11 is a mandatory prerequisite to a Claimant's right
       to commence any legal action with  respect to any claim for  benefits
       under this Plan.


                                 ARTICLE 12
                                Miscellaneous

12.1   Unsecured General Creditor.   Participants  and their  Beneficiaries,
       heirs,  successors  and  assigns  shall have  no  legal  or equitable
       rights, interest or claims in any property or assets of  an Employer.
       Any and  all  of  an Employer's  assets  shall be,  and  remain,  the
       general,  unpledged   unrestricted  assets  of  the   Employer.    An
       Employer's  obligation  under the  Plan shall  be  merely that  of an
       unfunded and unsecured promise  to pay money in the future.   Amounts
       payable to a Participant or his or her Beneficiary shall be paid from
       the general assets of an Employer exclusively.

12.2   Employer's  Liability.  An  Employer's liability  for the  payment of
       benefits shall be defined only by the Plan and the Plan Agreement, as
       entered into between  the Employer  and a Participant.   An  Employer
       shall have no  obligation to a  Participant under the Plan  except as
       expressly provided in the Plan.

12.3   Nonassignability.  Neither  a Participant nor any other  person shall
       have  any   right  to   commute,  sell,  assign,   transfer,  pledge,
       anticipate, mortgage or otherwise encumber, transfer, hypothecate  or
       convey in advance  of actual  receipt, the amounts,  if any,  payable
       hereunder, or  any part thereof, which  are, and all  rights to which
       are  expressly  declared  to  be unassignable  and  non-transferable,
       except  that  the foregoing  shall not  apply  to any  family support
       obligations  set forth  in a  court order.   No  part of  the amounts
       payable  shall, prior  to actual  payment, be  subject to  seizure or
       sequestration for  the payment  of any debts,  judgments, alimony  or
       separate maintenance owed by  a Participant or any other  person, nor
       be transferable by  operation of law in the event  of a Participant's
       or any other person's bankruptcy or insolvency.

12.4   Not a Contract of Employment.   The terms and conditions of this Plan
       shall  not be deemed to  constitute a contract  of employment between
       any  Employer  and  the  Participant.    Such  employment  is  hereby
       acknowledged to be an  "at will" employment relationship that  can be
       terminated at any time for any reason, with  or without cause, unless
       expressly provided in  a written  employment agreement.   Nothing  in
       this  Plan shall  be deemed  to give  a Participant  the right  to be
       retained  in  the service  of any  Employer or  to  be retained  as a
       director,  or  to  interfere  with  the  right  of  any  Employer  to
       discipline or discharge the Participant at any time.

12.5   Furnishing  Information.    A  Participant will  cooperate  with  the
       Committee by  furnishing any  and all  information  requested by  the
       Committee and take such other actions as may be requested in order to
       facilitate  the  administration  of  the  Plan and  the  payments  of
       benefits hereunder, including but not limited to taking such physical
       examinations as the Committee may deem necessary.

12.6   Terms.  Whenever any words are used herein in the singular or in  the
       plural,  they shall  be construed  as though  they were  used in  the
       plural or the singular, as the case  may be, in all cases where  they
       would so apply.

12.7   Captions.  The captions  of the articles, sections and  paragraphs of
       this Plan are for  convenience only and shall  not control or  affect
       the meaning or construction of any of its provisions.

12.8   Governing Law.   The provisions of  this Plan shall be  construed and
       interpreted according to the laws of the State of Arizona.

12.9   Validity.   In case any  provision of this  Plan shall be  illegal or
       invalid  for any  reason,  said illegality  or  invalidity shall  not
       affect the remaining parts  hereof, but this Plan shall  be construed
       and enforced as if such illegal and invalid provision had never  been
       inserted herein.

12.10  Notice.   Any notice or filing  required or permitted to  be given to
       the Committee under this Plan  shall be sufficient if in writing  and
       hand-delivered,  or  sent by  registered  or certified  mail,  to the
       address indicated below:

       If a Participant's Employer  is Pinnacle West Capital  Corporation or
       any other Employer other than Arizona Public Service Company, then to

              Pinnacle West Capital Corporation
              400 East Van Buren Street
              Post Office Box 52132
              Phoenix, Arizona  85072-2132
              Attn:  Human Resources

       If a Participant's Employer  is Arizona Public Service  Company, then
       to:

              Arizona Public Service Company
              400 North 5th Street
              P.O. Box 53999
              Phoenix, Arizona 85072-3999
              Attn: Manager, Compensation and Benefit
                     Station 8460

       Such notice shall be deemed  given as of the date of delivery  or, if
       delivery is made by mail, as of the date shown on the postmark on the
       receipt for registration or certification.

              Any notice or  filing required or permitted  to be given to  a
       Participant under this  Plan shall  be sufficient if  in writing  and
       hand-delivered,  or sent by  mail, to the  last known address  of the
       Participant.

12.11  Successors.  The provisions of this  Plan shall bind and inure to the
       benefit  of the Participant's Employer and its successors and assigns
       and  the  Participant,  the  Participant's  Beneficiaries,  and their
       permitted successors and assigns.

12.12  Spouse's  Interest.   The  interest in  the  benefits hereunder  of a
       spouse of  a Participant  who has  predeceased the  Participant shall
       automatically pass to the Participant  and shall not be  transferable
       by  such spouse  in any  manner,  including but  not limited  to such
       spouse's  will,  nor  shall such  interest  pass  under  the laws  of
       intestate succession.

12.13  Incompetent.   If the Committee  determines in its  discretion that a
       benefit under this Plan is to  be paid to a minor, a person  declared
       incompetent or to a  person incapable of handling the  disposition of
       that  person's property,  the Committee  may direct  payment of  such
       benefit  to the guardian,  legal representative or  person having the
       care and custody of such minor, incompetent or incapable person.  The
       Committee may require proof  of minority, incompetency, incapacity or
       guardianship, as it may deem appropriate prior to distribution of the
       benefit.  Any payment of a benefit shall be a payment for the account
       of the Participant and the Participant's Beneficiary, as the case may
       be, and shall be a complete discharge of any liability under the Plan
       for such payment amount.

12.14  Distribution in  the Event of Taxation.   If, for any  reason, all or
       any  portion of  a  Participant's  benefit  under this  Plan  becomes
       taxable to the Participant  prior to the Vesting Date,  a Participant
       may petition the Committee, if  prior to a Change in Control,  or the
       Trustee,  after a  Change in  Control, for  a distribution  of assets
       sufficient  to  meet  the  Participant's  tax  liability   (including
       additions to  tax, penalties and interest).  Upon the grant of such a
       petition, which grant shall not be unreasonably withheld, the Trustee
       shall  distribute  to the  Participant  from  the Trust,  immediately
       available  funds in an  amount equal  to that  Participant's federal,
       state and local  tax liability associated  with such taxation,  which
       liability shall  be measured by using that Participant's then current
       highest federal, state and local marginal tax rate, plus the rates or
       amounts for the applicable additions to  tax, penalties and interest.
       If the petition is  granted, the tax liability distribution  shall be
       made within  90 days of  the date when the  Participant's petition is
       granted.

              IN  WITNESS WHEREOF  the  Company and  Arizona Public  Service
Company have signed this amended and restated Supplemental Executive Benefit
Plan document on December 31, 1992.
