                  WHEREAS,  the  Executive is employed by the Company in various
managerial capacities,  possesses intimate knowledge of the business and affairs
of the Company, and has acquired certain confidential  information and data with
respect to the Company; and

                  WHEREAS,  the Company desires to insure,  insofar as possible,
that it will  continue to have the benefit of the  Executive's  services  and to
protect its confidential information and goodwill; and

                  WHEREAS,  the Company  recognizes that circumstances may arise
in which a change in the control of the Company through acquisition or otherwise
occurs  thereby  causing   uncertainty  of  employment  without  regard  to  the
Executive's competence or past contributions which uncertainty may result in the
loss of valuable  services of the  Executive to the detriment of the Company and
its shareholders,  and the Company and the Executive wish to provide  reasonable
security to the Executive  against changes in the Executive's  relationship with
the Company in the event of any such change in control; and

                  WHEREAS,  both the Company and the Executive are desirous that
a proposal for any change of control or  acquisition  will be  considered by the
Executive  objectively and with reference only to the business  interests of the
Company and its shareholders;

                  WHEREAS,  the  Executive  will  be  in a  better  position  to
consider the Company's  best  interests if the Executive is afforded  reasonable
security,  as  provided  in  this  Agreement,   against  altered  conditions  of
employment  which could  result from any such change in control or  acquisition;

                           respect  to such  number of years by four (4) (or the
                           number of years of the Executive's employment if less
                           than four (4) years); and

                                    (C) Equals one (1).

                  The Termination  Payment shall be payable in a lump sum on the
Executive's  Termination Date. Such lump sum payment shall not be reduced by any
present value or similar factor. The Executive shall not be required to mitigate
the amount of such payment by securing  other  employment  or otherwise and such
payment  shall  not be  reduced  by  reason  of  the  Executive  securing  other
employment or for any other reason.

                           (ii)  It is the  intention  of the  Company  and  the
         Executive  that no portion  of the  Termination  Payment  and any other
         payment under this Agreement,  or payments to or for the benefit of the
         Executive under any other  agreement,  plan or arrangement be deemed to
         be an "excess  parachute  payment"  as  defined in Section  280G of the
         Code. It is agreed that the present value of the Total  Payments  shall
         not exceed an amount  equal to two and  ninety-nine  hundredths  (2.99)
         times the Executive's  Base Period Income,  which is the maximum amount
         which the Executive  may receive  without  becoming  subject to the tax
         imposed  by  Section  4999 of the Code or  which  the  Company  may pay
         without loss of deduction  under Section  280G(a) of the Code.  Present
         value for purposes of this Agreement  shall be calculated in accordance
         with the  regulations  issued under  Section  280G of the Code.  Within
         sixty (60) days  following  delivery  of the Notice of  Termination  or
         notice by the  Company to the  Executive  of its belief that there is a
         payment or benefit  due the  Executive  which will  result in an excess
         parachute payment as defined in Section 280G of the Code, the Executive
         and the Company shall, at the Company's  expense,  obtain the opinions,
         which need not be  unqualified,  of legal counsel and certified  public
         accountants or a firm of recognized executive compensation consultants.
         The  Executive  shall  select  said  legal  counsel,  certified  public
         accountants and executive  compensation  consultants;  provided that if
         the Company does not accept one (1) or more of the parties  selected by
         the  Executive,  the Company shall provide the Executive with the names
         of such legal counsel,  certified public  accountants  and/or executive
         compensation  consultants as the Company  may select; if  the Executive
         does not accept the party or parties selected by the Company, the legal
         counsel,  certified public  accountants  and/or executive  compensation
         consultants  selected by the Executive  and the Company,  respectively,
         shall select the legal counsel,  certified  public  accountants  and/or
         executive compensation consultants,  whichever is applicable, who shall
         provide the opinions  required by this Section  6(b)(ii).  The opinions
         required  hereunder  shall set forth (a) the amount of the Base  Period
         Income of the  Executive,  (b) the present value of Total  Payments and
         (c) the amount and present value of any excess parachute  payments.  In
         the event that such  opinions  determine  that there would be an excess
         parachute  payment,  the  Termination  Payment  or  any  other  payment
         determined by such counsel to be includible in Total  Payments shall be
         reduced  or  eliminated  as  specified  by  the  Executive  in  writing
         delivered to the Company  within thirty (30) days of his or her receipt
         of such opinions or, if the  Executive  fails to so notify the Company,
         then as the Company shall reasonably determine, so that under the bases
         of  calculation  set  forth in such  opinions  there  will be no excess
         parachute payment.  The provisions of this Section 6(b)(ii),  including
         the  calculations,  notices and  opinions  provided for herein shall be
         based  upon  the  conclusive  presumption  that  the  compensation  and
         benefits  provided for in Section 4 hereof and any other  compensation,
         including but not limited to the Accrued  Benefits,  earned on or after
         the  date  of  Change  of  Control  by the  Executive  pursuant  to the
         Company's  compensation  programs if such payments would have been made
         in the future in any event,  even though the timing of such  payment is
         triggered by the Change of Control,  are  reasonable  compensation  for
         services  rendered prior to the Change of Control;  provided,  however,
         that in the event  legal  counsel so requests  in  connection  with the
         opinion  required  by  this  Section  6(b)(ii),  a firm  of  recognized
         executive compensation  consultants,  selected by the Executive and the
         Company  pursuant to the procedures  set forth above,  shall provide an
         opinion,   upon  which  such  legal   counsel  may  rely,   as  to  the
         reasonableness  of any item of compensation as reasonable  compensation
         for services  rendered prior to the Change of Control by the Executive.
         In the event that the  provisions of Sections 280G and 4999 of the Code
         are repealed without  succession,  this Section 6(b)(ii) shall be of no
         further force or effect.

                  7.   Death.  If the  Executive shall die during the Employment
Period, but after delivery of a Notice of Termination by the Company for reasons
other  than  Cause  or  disability  or by the  Executive  for Good  Reason,  the
Executive's  employment  shall  terminate  on his or her date of  death  and the
Executive's estate, heirs and beneficiaries shall be entitled to the Executive's
Accrued  Benefits as of the  Termination  Date,  all benefits  available to them
under the  Company's  benefits  plans as in effect  on the  Termination  Date on
account  of the  Executive's  death,  and,  subject  to the  provisions  of this
Agreement, to such Termination Payment as the Executive would have been entitled
to had the Executive  survived.  In such event,  the  Termination  Date shall be
sixty (60) days following  delivery of the Notice of Termination  subject to the
provisions of Section 12.

                  If the Executive shall die during the Employment  Period,  but
prior to the delivery of a Notice of  Termination,  the  Executive's  employment
shall  terminate  and the  Executive's  estate,  heirs and  beneficiaries  shall
receive all the Executive's  Accrued  Benefits  through the Termination Date and
all benefits available to them under the Company's benefit plans as in effect on
the Termination Date on account of the Executive's death.

                  8.   Retirement.   If,  during  the  Employment   Period,  the
Executive and the Company shall execute an agreement providing for the voluntary
retirement of the Executive from the Company,  the Executive  shall receive only
his or her Accrued Benefits through the Termination Date.

                  9.   Termination  for  Disability.  If,  as a  result  of  the
Executive's   Disability,   the  Executive  shall  have  been  absent  from  the
Executive's  duties  hereunder  on a  full-time  basis for five (5)  consecutive
months  during  the  Employment  Period,  and  within  sixty (60) days after the
Company  notifies the  Executive  in writing  that it intends to  terminate  the
Executive's employment, the Executive shall not have returned to the performance
of his or her  duties on a  full-time  basis,  the  Company  may  terminate  the
Executive's  employment,   subject  to  Section  12.  During  the  term  of  the
Executive's  Disability  prior to  termination,  the Executive shall continue to
receive  all salary  and  benefits  payable  under  Sections 4 and 5,  including
participation in all employee benefit plans,  programs and arrangements in which
the Executive was entitled to  participate  immediately  prior to the disability
provided that the  Executive's  continued  participation  is permitted under the
terms and provisions of such plans, programs and arrangements. In the event that
the Executive's participation in any such plan, program or arrangement is barred
as the result of such Disability,  the Executive shall be entitled to receive an
amount equal to the annual contributions, payments, credits or allocations which
would have been paid by the Company to the Executive, to the Executive's account
or on the Executive's behalf under such plans, programs and arrangements. In the
event the  Executive's  employment is  terminated on account of the  Executive's
Disability in accordance with this Section 9, the Executive shall receive his or
her Accrued  Benefits in  accordance  with  Section 6(a) hereof and shall remain
eligible for all benefits provided by any long-term  disability  programs of the
Company in effect at the time of such termination.

                  10.  Termination Not Giving Rise to a Termination Payment. If,
during the  Employment  Period,  the  Executive's  employment is terminated  for
Cause, or if the Executive  voluntarily  terminates his or her employment  other
than for Good  Reason,  subject to the  procedures  set forth in Section 12, the
Executive  shall be  entitled  to receive  only his or her  Accrued  Benefits in
accordance with Section 6(a).

                  11.  Termination  Giving Rise to a  Termination  Payment.  If,
during the Employment  Period,  the Executive's  employment is terminated by the
Executive  for Good  Reason  or by the  Company  other  than by reason of death,
Disability  pursuant to Section 9 or Cause,  subject to the procedures set forth
in Section 12,

                           (a) the  Executive  shall be  entitled to receive and
         the Company shall pay the  Executive's  Accrued  Benefits in accordance
         with Section 6(a) and, in lieu of further  salary  payments for periods
         following  the  Termination  Date,  as  severance  pay,  a  Termination
         Payment;

                           (b) the  Executive  and his or her  dependents  shall
         continue  to be  covered  for one (1) year,  under  the same  terms and
         conditions,  by the medical plan and/or  dental plan  maintained by the
         Company which covered that Executive and his or her dependents prior to
         the Executive's  Termination  Date. The Executive and the Company shall
         share the cost of such  continued  coverage in the same  proportions as
         they  shared  the  cost  of  such  coverage  prior  to the  Executive's
         Termination  Date. For purposes of satisfying the Company's  obligation
         under the Consolidated  Omnibus Budget  Reconciliation Act ("COBRA") to
         continue  group health care  coverage to the  Executive  and his or her
         dependents as a result of the  Executive's  termination  of employment,
         the period  during  which the  Executive  is  permitted  to continue to
         participate  in the Company's  medical plans and/ or dental plans under
         this  Section  11(b) shall be taken into account and treated as part of
         the period  during which the Executive  and his or her  dependents  are
         entitled to continued  coverage under the Company's  group health plans
         under COBRA.  Following the end of the continuation period specified in
         this Section 11(b),  the Executive and his or her  dependents  shall be
         covered under such plans and  arrangements  only as required  under the
         provisions of COBRA;

                           (c) the Executive's termination shall be treated as a
         "Normal   Termination"   as  defined  in  the  Pinnacle   West  Capital
         Corporation  Stock Option and  Incentive  Plan, as amended from time to
         time,  and in  any  successor  plan thereto,  which  shall  entitle the
         Executive to exercise any  outstanding  stock options  during the three
         (3) month period beginning on the Executive's Termination Date, and any
         restrictions  remaining on any  "Restricted  Stock" (as defined in such
         plan)  awarded to the Executive  shall lapse on his or her  Termination
         Date; and

                           (d) "out-placement"  services will be provided by the
         Company to the  Executive  for a period  beginning  on the  Executive's
         Termination Date. Such services shall be provided for a period equal to
         one (1) week per year of service with the Company or an affiliate, plus
         one (1)  week for each two (2)  years  by  which  the  Executive's  age
         exceeds age forty (40), plus one (1) week for each Ten Thousand Dollars
         ($10,000)  of  compensation,  but in no event less than six (6) months.
         Notwithstanding  the foregoing,  the Executive's right to out-placement
         services  shall  terminate  on the  earlier  of the date on  which  the
         Executive  becomes employed in a position  commensurate with his or her
         current  salary and  responsibilities  or on the last day of the period
         determined pursuant to the formula set forth in this Section 11(d). The
         "out-placement"  services shall be provided by an out-placement company
         selected by the Company.

                  12.  Termination  Notice and Procedure. Any termination by the
Company or the Executive of the  Executive's  employment  during the  Employment
Period shall be  communicated  by written Notice of Termination to the Executive
if such Notice is  delivered by the Company and to the Company if such Notice is
delivered by the Executive, all in accordance with the following procedures:

                           (a) The  Notice of  Termination  shall  indicate  the
         specific termination  provision in this Agreement relied upon and shall
         set forth in reasonable detail the facts and  circumstances  alleged to
         provide a basis for termination.

                           (b) Any Notice of Termination by the Company shall be
         approved by a resolution duly adopted by a majority of the directors of
         the  Company  then in office,  specifying  in detail the basis for such
         termination.

                           (c) If the Company shall give a Notice of Termination
         for Cause or by reason of  Disability  and the  Executive in good faith
         notifies the Company that a dispute exists  concerning such termination
         within the fifteen (15) day period following the Executive's receipt of
         such notice,  the Executive may elect to continue his or her employment
         during such dispute. If it is thereafter determined that (i) the reason
         given  by the  Company  for  termination  did  exist,  the  Executive's
         Termination  Date  shall be the  earlier  of (A) the date on which  the
         dispute is finally  determined,  either by mutual written  agreement of
         the parties or  pursuant  to Section 14, (B) the date of the  Company's
         Notice of Termination for Cause, (C) the date of the Executive's death,
         or (D)  one day  prior  to the end of the  Employment  Period,  and the
         Executive  shall not be  entitled  to a  Termination  Payment  based on
         events occurring after the Company delivered its Notice of Termination;
         or (ii) the reason given by the Company for  termination did not exist,
         the  employment of the Executive  shall  continue as if the Company had
         not  delivered  its  Notice  of  Termination  and  there  shall  be  no
         Termination Date arising out of such notice.

                           (d) If the  Executive  shall  in  good  faith  give a
         Notice of  Termination  for Good  Reason and the Company  notifies  the
         Executive that a dispute exists  concerning the termination  within the
         fifteen (15) day period following the Company's receipt of such notice,
         the Executive may elect to continue his or her  employment  during such
         dispute. If it is thereafter determined that (i) Good Reason did exist,
         the Executive's  Termination  Date shall be the earlier of (A) the date
         on which the dispute is finally  determined,  either by mutual  written
         agreement of the parties or by a court of competent  jurisdiction,  (B)
         the date of the  Executive's  death, or (C) one day prior to the end of
         the Employment  Period, and the Executive's  Termination  Payment shall
         reflect  events  occurring  after the  Executive  delivered  his or her
         Notice  of  Termination;  or  (ii)  Good  Reason  did  not  exist,  the
         employment of the Executive shall continue after such  determination as
         if the Executive had not delivered the Notice of Termination  asserting
         Good Reason.

                           (e) If the  Executive  does  not  elect  to  continue
         employment  pending  resolution  of a  dispute  regarding  a Notice  of
         Termination under Sections 12(c) and (d), and it is finally  determined
         that the reason for termination set forth in such Notice of Termination
         did not exist,  if such  notice was  delivered  by the  Executive,  the
         Executive  will be deemed  to have  voluntarily  terminated  his or her
         employment and if delivered by the Company,  the Company will be deemed
         to have  terminated  the  Executive  other  than by  reason  of  death,
         disability or Cause.

                           (f) If the opinion required to be delivered  pursuant
         to Section 6(b)(ii) shall not have been delivered on or before the date
         that would otherwise  constitute the Termination  Date, the Termination
         Date shall be delayed to the earlier of the date on which such  opinion
         is delivered or one (1) day prior to the end of the Employment Period.

                  13.      Obligations of the Executive.

                           (a)  The   Executive   agrees  that  if,  during  the
         Employment Period, the Executive's employment is terminated in a manner
         entitling the  Executive to a Termination  Payment or the Executive has
         voluntarily terminated his or her employment,  the Executive shall not,
         for a period  commencing on the  Termination  Date and ending after one
         (1)  year,  (i) act in a  similar  capacity  for any  electric  utility
         company which competes to a substantial  degree with the Company in the
         State of Arizona or (ii) engage in any activity  involving  substantial
         competition  with the Company in the electric  utility  industry in the
         State of Arizona,  without the prior written  approval of the Company's
         Board of  Directors;  provided,  however,  that nothing in this Section
         13(a)  shall   prohibit  the  Executive  from  owning  stock  or  other
         securities of a competitor  amounting to less than twenty percent (20%)
         of the stated capital of such competitor.

                           (b) The Executive  covenants  and agrees,  during the
         Executive's  employment  by  the  Company  and  following  his  or  her
         Termination  Date, to hold in strict confidence any and all information
         in the Executive's possession as a result of the Executive's employment
         with the  Company;  provided  that nothing in this  Agreement  shall be
         construed as  prohibiting  the Executive  from  reporting any suspected
         instance of illegal activity of any nature, any nuclear safety concern,
         any workplace safety concern or any public safety concern to the United
         States Nuclear Regulatory Commission, United States Department of Labor
         or  any  federal  or  state  governmental  agency  or  prohibiting  the
         Executive  from  participating  in  any  way in any  state  or  federal
         administrative,  judicial or  legislative  proceeding or  investigation
         with respect to any such claims and matters.

                  14.  Arbitration.  All claims,  disputes and other  matters in
question between the parties arising under this Agreement, other than Section 13
which may be enforced by the Company through injunctive relief, shall be decided
by  arbitration  in  accordance  with  the  rules  of the  American  Arbitration
Association,  unless the  parties  mutually  agree  otherwise.  Any  arbitration
required  under this  Agreement  shall be held in Phoenix,  Arizona,  unless the
parties  mutually agree  otherwise.  The Company shall pay the costs of any such
arbitration.  The award by the  arbitrator  shall be final,  and judgment may be
entered upon it in accordance  with applicable law in any state or Federal court
having jurisdiction thereof.

                  15.  Expenses  and  Interest.  If, after a Change of Control a
good faith  dispute  arises with respect to  the enforcement of the  Executive's
rights under this Agreement or if any arbitration or legal  proceeding  shall be
brought in good faith to enforce or interpret any provision contained herein, or
to recover damages for breach hereof and the Executive is the prevailing  party,
the Executive shall recover from the Company any reasonable  attorney's fees and
necessary costs and disbursements  incurred as a result of such dispute or legal
proceeding,  and  prejudgment  interest  on any money  judgment  obtained by the
Executive  calculated  at the rate of interest  announced by Bank One of Arizona
from time to time as its prime rate from the date that payments to the Executive
should have been made under this Agreement.

                  16. Payment  Obligations  Absolute.  The Company's  obligation
during and after the Employment Period to pay the Executive the compensation and
to make the arrangements provided herein shall be absolute and unconditional and
shall not be affected by any circumstances,  provided that the Company may apply
amounts  payable  under this  Agreement  to any debts owed to the Company by the
Executive on his or her Termination  Date, and provided  further that the amount
payable  under  this  Agreement  shall be offset by any  amounts  payable to the
Executive under a separate severance plan, agreement or arrangement  established
by the  Company  so that in no event  shall the  total  amount  received  by the
Executive be more than the amount permitted under Section 6(b)(ii).  All amounts
payable by the Company  under this  Agreement  shall be paid  without  notice or
demand. Each and every payment made under this Agreement by the Company shall be
final.  Notwithstanding the foregoing, in the event that the Company has paid an
Executive  more than the amount to which the  Executive  is entitled  under this
Agreement,  the Company  shall have the right to recover all or any part of such
overpayment from the Executive or from whomsoever has received such amount.

                  17.  Successors.  (a)  If  all  or  substantially  all  of the
Company's  business and assets are sold,  assigned or transferred to any Person,
or if the Company  merges into or  consolidates  or otherwise  combines with any
Person which is a continuing or successor entity,  then the Company shall assign
all of its right,  title and  interest in this  Agreement as of the date of such
event to the Person which is either the acquiring or successor corporation,  and
such Person shall assume and perform from and after the date of such  assignment
the terms, conditions and provisions imposed by this Agreement upon the Company.
Failure  of the  Company  to obtain  such  assignment  shall be a breach of this
Agreement.  In case of such  assignment  by the  Company and of  assumption  and
agreement by such Person, all further rights as well as all other obligations of
the Company  under this  Agreement  thenceforth  shall cease and  terminate  and
thereafter the expression "the Company"  wherever used herein shall be deemed to
mean such Person(s).

                           (b)   This  Agreement and all rights of the Executive
         shall inure to the  benefit of and be  enforceable  by the  Executive's
         personal or legal representatives,  estates, executors, administrators,
         heirs and  beneficiaries.  In the event of the Executive's  death,  all
         amounts  payable to the Executive under this Agreement shall be paid to
         the Executive's estate, heirs and representatives. This Agreement shall
         inure to the benefit  of, be binding  upon and be  enforceable  by, any
         successor,  surviving or resulting corporation or other entity to which
         all or substantially all of the Company's  business and assets shall be
         transferred  whether by merger,  consolidation,  transfer or sale. This
         Agreement  shall not be  terminated  by the  voluntary  or  involuntary
         dissolution of the Company.
