                KEY EXECUTIVE EMPLOYMENT AND SEVERANCE AGREEMENT

         THIS AGREEMENT, made and entered into as of the _____ day of
____________, 2006, by and between Pinnacle West Capital Corporation, an Arizona
corporation (hereinafter referred to as the "Company") and __________________
(hereinafter referred to as the "Executive"):

                               W I T N E S S E T H

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

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

         WHEREAS, the Company recognizes that circumstances may arise in which a
change in the control of the Company or Arizona Public Service Company, a
subsidiary 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
best interests of the Company 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; and

         NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements hereinafter set forth, the parties hereto mutually
covenant and agree as follows:

employ the Executive during the Employment Period.

         3. Duties. During the Employment Period, the Executive shall, in the
same capacities and positions held by the Executive at the time of such Change
of Control or in such other capacities and positions as may be agreed to by the
Employer and the Executive in writing, devote the Executive's reasonable best
efforts, attention and skill to the business and affairs of the Company, as such

                                      -5-

and as they may hereafter be conducted. The services which are to be performed
by the Executive hereunder are to be rendered at an employment location which is
not more than seventy-five (75) miles from the Executive's employment location
on the date of the Change of Control, or in such other place or places as shall
be mutually agreed upon in writing by the Executive and the Employer from time
to time. The Executive shall not be required to be absent from such employment
location for more than forty-five (45) consecutive days in any fiscal year
without the Executive's consent.

         4. Compensation. During the Employment Period, the Executive shall be
compensated as follows:

         (a) The Executive shall receive, at such intervals and in accordance
with such standard policies as may be in effect on the date of the Change of
Control, an annual salary not less than the Executive's annual salary as in
effect as of the date of the Change of Control, subject to adjustment as
provided in Section 5;

         (b) The Executive shall be reimbursed, at such intervals and in

         (c) The Executive shall be included to the extent eligible thereunder
in any and all plans providing general benefits for the Employer's employees,
including but not limited to, group life insurance, disability, medical, dental,
pension, profit sharing, savings and stock bonus plans and be provided any and
all other benefits and perquisites made available to other employees of
comparable status and position, on the same terms and conditions as generally
provided to employees of comparable status and position;

         (d) The Executive shall receive annually not less than the amount of
paid vacation and not fewer than the number of paid holidays received annually
immediately prior to the Change of Control or such greater amount of paid
vacation and number of paid holidays as may be made available annually to other
employees of comparable status and position with the Employer; and

         (e) The Executive shall be included in all plans providing special
benefits to corporate officers, including but not limited to bonus, deferred
compensation, incentive compensation, supplemental pension, stock option, stock
appreciation, stock bonus and similar or comparable plans extended by the
Company or the Employer from time to time to corporate officers, key employees
and other employees of comparable status.

         5. Annual Compensation Adjustments. During the Employment Period, the
Board of Directors of the Employer, an appropriate committee of the Board or the
President of the Employer, whichever is appropriate, shall consider and
appraise, at

                                      -6-
<PAGE>

least annually, the Executive's compensation. In determining such compensation,
the Board, the appropriate committee thereof or the President, whichever is
appropriate, shall consider the commensurate increases given to other corporate
officers and key employees generally, the scope and success of the Employer's
operations, the expansion of Executive's duties and the Executive's performance
of his duties.

         6. Payments Upon Termination.

         (a) Accrued Benefits. For purposes of this Agreement, the Executive's
Accrued Benefits shall include the following amounts: (i) all salary earned or
accrued through the Termination Date; (ii) reimbursement for any and all monies
advanced in connection with the Executive's employment for reasonable and
necessary expenses incurred by the Executive through the Termination Date; (iii)
a lump sum payment of the bonus or incentive compensation otherwise payable to
the Executive under the terms of any bonus or incentive compensation plan or
plans for the year in which termination occurs; and (iv) all other payments and
benefits to which the Executive may be entitled under the terms of any benefit
plan of the Company or the Employer. Payment of Accrued Benefits shall be made
promptly in accordance with the Employer's prevailing practice and the terms of
any applicable benefit plans, contracts or arrangements.

         (b) Termination Payment. For purposes of this Agreement, the
Executive's Termination Payment shall be an amount equal to (i) plus (ii),
multiplied by (iii), where

                  (i) Equals the Executive's rate of annual salary, as in effect
         on the date of the Change of Control and as increased thereafter from
         time to time pursuant to Section 5;

                  (ii) Equals the amount of the average annual dollar award paid
         (or payable but deferred by the Executive) to the Executive pursuant to
         the Employer's regular annual bonus plan or arrangement with respect to
         the four (4) years (or for such lesser number of years prior for which
         the Executive was eligible to earn such a bonus, and annualized in the
         case of any bonus earned and payable for a partial fiscal year)
         preceding the Termination Date which shall be determined by dividing
         the total dollar amount paid (or payable but deferred by the Executive)
         to the Executive under such plan or arrangement with respect to such
         number of years by four (4) (or for such lesser number of years prior
         to which the Executive was eligible to earn such a bonus, and
         annualized in the case of any bonus earned and payable for a partial
         fiscal year); and

                  (iii) Equals three (3).

         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

                                      -7-
<PAGE>

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, except as provided in Section 16.

         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 shall be entitled to receive the Executive's Accrued Benefits as of the
Termination Date and, subject to the provisions of this Agreement, to such
Termination Payment as the Executive would have been entitled to had the
Executive survived. All benefits payable on account of the Executive's
employment or death under the Company's or Employer's employee benefits plans,
programs or arrangements shall be paid or distributed in accordance with the
terms of such plans, programs or arrangements. The Executive's death following
delivery of the Notice of Termination shall not affect his or her Termination
Date which shall be determined without regard to the Executive's death, 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
Employer shall execute an agreement providing for the voluntary retirement of
the Executive from the Employer, the Executive shall receive only his or her
Accrued Benefits through the Termination Date. Without limiting the generality
of the foregoing, the Executive's resignation under this Agreement with or
without Good Reason, shall in no way affect the Executive's ability to terminate
employment by reason of the Executive's "retirement" under any of the Company's
retirement or pension plans or to be eligible to receive benefits under any
retirement or pension plan of the Company and its affiliates or substitute plans
adopted by the Company or its successors, and any termination which otherwise
qualifies as Good Reason shall be treated as such even if it is also a
"retirement" for purposes of any such plan.

         9. Termination for Disability. If the Executive has been absent from
his or her duties hereunder on a full-time basis for five (5) consecutive months
during the Employment Period on account of a Disability, the Employer may
provide a Notice of Termination, which satisfies the requirements of Section 12,
and the Executive's employment shall, for purposes of this Agreement, terminate
sixty (60) days thereafter, unless the Executive returns to the performance of
his or her duties on a full-time basis prior to the end of the sixty (60) day
period. During the term of the Executive's Disability prior to his or her
Termination Date, the Executive shall continue to participate in all
compensation and benefit plans, programs and arrangements in which the Executive
was entitled to participate immediately prior to his or her Disability in
accordance with

                                      -8-
<PAGE>

the terms and provisions of such plans, programs and arrangements. If the
Executive's employment is terminated on account of the Executive's Disability,
the Executive shall receive his or her Accrued Benefits in accordance with
Section 6(a) hereof, provided that the Executive's termination for purposes of
this Agreement under this Section 9 shall not affect his or her entitlement to
benefits on account of his or her Disability under any long-term disability
programs of the Company or the Employer in effect at the time of such
termination and in which the Executive participated immediately prior to his or
her Disability.

         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 Employer 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
         or the Employer, as applicable, 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 eligible dependents shall continue
         to be covered until the end of the second calendar year following the
         year in which the Termination Date occurs, under the same terms and
         conditions, by the medical plan, dental plan and/or group life
         insurance plan maintained by the Company or the Employer which covered
         that Executive and his eligible dependents prior to the Executive's
         Termination Date. Notwithstanding the foregoing, if the Company's or
         Employer's medical plan, dental plan and/or group life insurance plan
         covering the Executive on his or her Termination Date was amended,
         replaced or terminated on or after the Change of Control and such
         action would constitute Good Reason within the meaning of Section 1(l),
         the Executive and his or her eligible dependents shall be entitled to
         continued coverage for purposes of this Section 11(b) under the terms
         of the medical plan, dental plan and/or group life insurance plan which
         they participated in immediately prior to the Change of Control. If the
         affected plan is no longer available, the Company shall make
         arrangements to provide equivalent coverage to the Executive and his or
         her eligible dependents. For this purpose, "equivalent coverage" shall
         mean medical, dental and/or life insurance coverage, which, when added
         to the coverage provided to the Executive and his or her eligible
         dependents under the Company's or Employer's medical plan, dental plan
         and/or group life insurance plan in effect on the Executive's
         Termination Date, equals or exceeds the level of benefits provided
         under the medical plan, dental plan and/or group life insurance plan to
         the Executive and his or her eligible dependents on the day immediately
         preceding

                                      -9-
<PAGE>

         the Change of Control. The Executive and the Employer shall share the
         cost of the continued coverage under this Section 11(b) in the same
         proportions as the Employer and similarly situated active employees
         shared the cost of such coverage on the day preceding the Executive's
         Termination Date. For purposes of satisfying the Company's or
         Employer's obligation under the Consolidated Omnibus Budget
         Reconciliation Act ("COBRA") to continue group health care coverage to
         the Executive and his eligible 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 or
         Employer's medical plans and/or dental plans under this Section 11(b)
         shall not be taken into account and treated as part of the period
         during which the Executive and his eligible dependents are entitled to
         continued coverage under the Company's or Employer's group health plans
         under COBRA. Following the end of the continuation period specified in
         this Section 11(b), the Executive and his eligible 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, or in the
         Pinnacle West Capital Corporation 2002 Long-Term Incentive Plan or 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 beginning on the
         Executive's Termination Date and ending 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 the last day of the
         twelve (12) month period which began on the Executive's Termination
         Date. 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 Employer
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.

                                      -10-
<PAGE>

                  (b) Any Notice of Termination by the Company shall be approved
         by a resolution duly adopted by a majority of the members of the
         Company's board of directors then in office.

                  (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 pursuant to Section 14, (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.

         13. Obligations of the Executive. The Executive covenants and agrees,
during the Executive's employment with the Employer 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
Employer; provided that nothing in this Agreement shall be construed as
prohibiting the Executive from reporting any

                                      -11-
<PAGE>

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, shall
be decided by arbitration in accordance with the commercial arbitration 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.

         The Company shall not be required to arbitrate claims arising under
Section 13. The Company shall have the right to judicial enforcement of its
rights under Section 13, including, but not limited to, injunctive relief.

         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 JP Morgan Chase Bank
N.A. (or any successor thereto) from time to time as its prime rate from the
date that payments to the Executive should have been made under this Agreement.
Any payment due under this section will be made on the fifth business day
following the date the dispute is final.

         16. Payment Obligations Absolute. The Company's obligation during and
after the Employment Period to insure that the compensation and arrangements
provided herein are provided to the Executive 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 loan or other
debts then owed to the Company or an Affiliate by the Executive, the terms of
which are reflected in a written document signed by the Executive. Nothing in
this Agreement shall prevent or limit the Executive's continuing or future
participation in any plan, program, policy or practice provided by the Company
or its Affiliates and for which the Executive may qualify, nor shall anything
herein limit or otherwise affect such rights as the Executive may have under any
other contract or agreement with the Company or its Affiliates. Amounts that are
vested benefits or that the Executive is otherwise entitled to receive under any
plan, policy, practice or program of or any other contract or agreement with the
Company or its Affiliates at or subsequent to the Termination Date shall be
payable in accordance

                                      -12-
<PAGE>

with such plan, policy, practice or program or contract or agreement, except as
explicitly modified by this Agreement. Notwithstanding the foregoing, the
amounts payable under this Agreement shall be in lieu of any amounts payable to
the Executive under a separate severance plan, agreement or arrangement
established by the Company. 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. 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.

         18. Enforcement. The provisions of this Agreement shall be regarded as
divisible, and if any of said provisions or any part hereof are declared invalid
or unenforceable by a court of competent jurisdiction, the validity and
enforceability of the remainder of such provisions or parts hereof and the
applicability thereof shall not be affected thereby.

         19. Amendment or Termination. The term of this Agreement shall run
until December 31, 2007, and shall continue for additional one (1) year periods
thereafter, unless the Company notifies the Executive in writing six (6) months
prior to Decem-

                                      -13-
<PAGE>

ber 31, 2007 (or the anniversary of that date in the event the Agreement
continues beyond that date pursuant to the provisions of this Section 19) that
it does not intend to continue the Agreement. Notwithstanding the foregoing, (i)
if a Change of Control has occurred on or before the date on which the Agreement
would be terminated by the Company in accordance with this Section 19, the
Agreement shall not terminate with respect to that Change of Control until the
end of the Employment Period, and (ii) this Agreement shall terminate if, prior
to a Change in Control, the Executive ceases to be employed by the Employer as a
corporate officer.

         This Agreement sets forth the entire agreement between the Executive
and the Company with respect to the subject matter hereof, and supersedes all
prior oral or written negotiations, commitments, understandings and writings
with respect thereto.

         This Agreement may not be terminated, amended or modified during its
term as specified above except by written instrument executed by the Company and
the Executive.

         20. Withholding. The Company and the Employer shall be entitled to
withhold from amounts to be paid to the Executive under this Agreement any
federal, state or local withholding or other taxes or charges which it is from
time to time required to withhold. The Company and the Employer shall be
entitled to rely on an opinion of counsel if any question as to the amount or
requirement of any such withholding shall arise.

         21. Venue; Governing Law. This Agreement and the Executive's and
Company's respective rights and obligations hereunder shall be governed by and
construed in accordance with the laws of the State of Arizona. Any action
concerning this Agreement shall be brought in the Federal or state courts
located in the County of Maricopa, Arizona, and each party consents to the venue
and jurisdiction of such courts.

         22. Notice. Notices given pursuant to this Agreement shall be in
writing and (a) if hand delivered, shall be deemed given when delivered, and (b)
if mailed, shall be deemed delivered when placed in the United States mail,
postage prepaid, addressed,

or to such other addresses as the parties may provide written notice of to each
other, from time to time, in accordance with this Section 22.

         23. Funding. Benefits payable under this Agreement shall constitute an
unfunded general obligation of the Company payable from its general assets, and
the Company shall not be required to establish any special fund or trust for
purposes of paying benefits under this Agreement. The Executive shall not have
any vested right to any particular assets of the Company as a result of
execution of this Agreement and shall be a general creditor of the Company.

         24. No Waiver. No waiver by either party at any time of any breach by
the other party of, or compliance with, any condition or provision of this
Agreement to be performed by the other party shall be deemed a waiver of similar
or dissimilar provisions or conditions at the same time or any prior or
subsequent time.

         25. Headings. The headings contained are for reference only and shall
not affect the meaning or interpretation of any provision of this Agreement.

         26. Additional Payment.

                  (a) Anything in this Agreement to the contrary
         notwithstanding, in the event it shall be determined that any Payment
         would be subject to the Excise Tax, then the Executive shall be
         entitled to receive an additional payment (the "Gross-Up Payment") in
         an amount such that, after payment by the Executive of all taxes (and
         any interest or penalties imposed with respect to such taxes),
         including, without limitation, any income taxes (and any interest and
         penalties imposed with respect thereto) and Excise Tax imposed upon the
         Gross-Up Payment, the Executive retains an amount of the Gross-Up
         Payment equal to the Excise Tax imposed upon the Payments. The
         Company's obligation to make Gross-Up Payments under this Section 26
         shall not be conditioned upon the Executive's termination of
         employment.

                  (b) Subject to the provisions of Section 26(c), all
         determinations required to be made under this Section 26, including
         whether and when a Gross-Up Payment is required, the amount of such
         Gross-Up Payment and the assumptions to be utilized in arriving at such
         determination, shall be made by a nationally-recognized accounting firm
         appointed by the Company prior to a Change of Control (the "Accounting
         Firm"). The Accounting Firm shall provide detailed supporting
         calculations both to the Company and the Executive within 15 business
         days of the receipt of notice from the Executive that there has been a
         Payment or such earlier time as is requested by the Company. In the
         event that the Accounting Firm is serving as accountant or auditor for
         the individual, entity or group effecting the Change of Control, the
         Executive may appoint another nationally recognized accounting firm to
         make the determinations required hereunder (which accounting firm shall
         then be referred to as the Accounting Firm hereunder). All

                                      -15-
<PAGE>

         fees and expenses of the Accounting Firm shall be borne solely by the
         Company. Any Gross-Up Payment, as determined pursuant to this Section
         26, shall be paid by the Company to the Executive within 5 days of the
         receipt of the Accounting Firm's determination, but in all events by
         the March 15 following the calendar year in which the event giving rise
         to payment occurs. Any determination by the Accounting Firm shall be
         binding upon the Company and the Executive. As a result of the
         uncertainty in the application of Section 4999 of the Code at the time
         of the initial determination by the Accounting Firm hereunder, it is
         possible that Gross-Up Payments that will not have been made by the
         Company should have been made (the "Underpayment"), consistent with the
         calculations required to be made hereunder. In the event the Company
         exhausts its remedies pursuant to Section 26(c) and the Executive
         thereafter is required to make a payment of any Excise Tax, the
         Accounting Firm shall determine the amount of the Underpayment that has
         occurred and any such Underpayment shall be promptly paid by the
         Company to or for the benefit of the Executive.

                  (c) The Executive shall notify the Company in writing of any
         claim by the Internal Revenue Service that, if successful, would
         require the payment by the Company of the Gross-Up Payment. Such
         notification shall be given as soon as practicable, but no later than
         10 business days after the Executive is informed in writing of such
         claim. The Executive shall apprise the Company of the nature of such
         claim and the date on which such claim is requested to be paid. The
         Executive shall not pay such claim prior to the expiration of the
         30-day period following the date on which the Executive gives such
         notice to the Company (or such shorter period ending on the date that
         any payment of taxes with respect to such claim is due). If the Company
         notifies the Executive in writing prior to the expiration of such
         period that the Company desires to contest such claim, the Executive
         shall:

                           (i) give the Company any information reasonably
                  requested by the Company relating to such claim,

                           (ii) take such action in connection with contesting
                  such claim as the Company shall reasonably request in writing
                  from time to time, including, without limitation, accepting
                  legal representation with respect to such claim by an attorney
                  reasonably selected by the Company,

                           (iii) cooperate with the Company in good faith in
                  order effectively to contest such claim, and

                           (iv) permit the Company to participate in any
                  proceedings relating to such claim;

         provided, however, that the Company shall bear and pay directly all
         costs and expenses (including additional interest and penalties)
         incurred in connection with such contest, and shall indemnify and hold
         the Executive harmless, on an after-

                                      -16-
<PAGE>

         tax basis, for any Excise Tax or income tax (including interest and
         penalties) imposed as a result of such representation and payment of
         costs and expenses. Without limitation on the foregoing provisions of
         this Section 26(c), the Company shall control all proceedings taken in
         connection with such contest, and, at its sole discretion, may pursue
         or forgo any and all administrative appeals, proceedings, hearings and
         conferences with the applicable taxing authority in respect of such
         claim and may, at its sole discretion, either pay the tax claimed to
         the appropriate taxing authority on behalf of the Executive and direct
         the Executive to sue for a refund or contest the claim in any
         permissible manner, and the Executive agrees to prosecute such contest
         to a determination before any administrative tribunal, in a court of
         initial jurisdiction and in one or more appellate courts, as the
         Company shall determine; provided, however, that, if the Company pays
         such claim and directs the Executive to sue for a refund, the Company
         shall indemnify and hold the Executive harmless, on an after-tax basis,
         from any Excise Tax or income tax (including interest or penalties)
         imposed with respect to such payment or with respect to any imputed
         income in connection with such payment; and provided, further, that any
         extension of the statute of limitations relating to payment of taxes
         for the taxable year of the Executive with respect to which such
         contested amount is claimed to be due is limited solely to such
         contested amount. Furthermore, the Company's control of the contest
         shall be limited to issues with respect to which the Gross-Up Payment
         would be payable hereunder, and the Executive shall be entitled to
         settle or contest, as the case may be, any other issue raised by the
         Internal Revenue Service or any other taxing authority.

                  (d) If, after the receipt by the Executive of a Gross-Up
         Payment or payment by the Company of an amount on the Executive's
         behalf pursuant to Section 26(c), the Executive becomes entitled to
         receive any refund with respect to the Excise Tax to which such
         Gross-Up Payment relates or with respect to such claim, the Executive
         shall (subject to the Company's complying with the requirements of
         Section 26(c), if applicable) promptly pay to the Company the amount of
         such refund (together with any interest paid or credited thereon after
         taxes applicable thereto). If, after payment by the Company of an
         amount on the Executive's behalf pursuant to Section 26(c), a
         determination is made that the Executive shall not be entitled to any
         refund with respect to such claim and the Company does not notify the
         Executive in writing of its intent to contest such denial of refund
         prior to the expiration of 30 days after such determination, then the
         amount of such payment shall offset, to the extent thereof, the amount
         of Gross-Up Payment required to be paid.

                  (e) Notwithstanding any other provision of this Section 26,
         the Company may, in its sole discretion, withhold and pay over to the
         Internal Revenue Service or any other applicable taxing authority, for
         the benefit of the Executive, all or any portion of any Gross-Up
         Payment, and the Executive hereby consents to such withholding.

         27. Section 409A Savings Clause. If any compensation or benefits
provided by this Agreement may result in the application of Section 409A of the
Code, the

                                      -17-

          4.   PAYMENT.

               (a)  PERFORMANCE SHARES PAYABLE IN COMMON STOCK. Subject to early
                    termination of this Award Agreement pursuant to Section 7
                    below, as soon as practicable following the end of the
                    Performance Period and the determination of the Company's
                    Earnings Per Share Growth Rate (as defined herein) as
                    compared to the Earnings Per Share Growth Rate of the S&P

                    above, the Company will also deliver to Employee a cash
                    payment equal to the amount of dividends that Employee would
                    have received if Employee had directly owned all of such
                    Common Stock during the Performance Period, plus interest on
                    such amount at the rate of _____ percent, compounded

          5.   PERFORMANCE CRITERIA AND ADJUSTMENTS.

               ADJUSTMENT OF BASE GRANT. The Base Grant will increase or
               decrease based upon the Company's "Earnings Per Share Growth
               Rate" as compared to the Earnings Per Share Growth Rate of the
               S&P Electric Utilities Index during the Performance Period, as
               follows:

                     IF THE COMPANY'S EARNINGS PER SHARE            THE NUMBER OF

                PERIOD AS COMPARED TO S&P ELECTRIC UTILITIES
                                INDEX IS:

                --------------------------------------------  ---------------------------
<S>                                                           <C>
                     ___th Percentile or Greater                  ___ X Base Grant
                          ___th Percentile                        ___ X Base Grant
                          ___th Percentile                           Base Grant
                          ___th Percentile                        ___ X Base Grant
                      Less than ___th Percentile              [None / ___X Base Grant]
</TABLE>

                    If intermediate percentiles are achieved, the number of
               Performance Shares awarded will be prorated (partial shares will
               be rounded down to the nearest whole share when applicable). For
               example, if the Company's Earnings Per Share Growth Rate during
               the Performance Period places the Company's performance in the
               ___th percentile, then the number of Performance Shares would be
               increased to ______ multiplied by the Base Grant. In no event
               will Employee be entitled to receive a number of Performance
               Shares greater than ___ times the Base Grant, even if the
               Company's Earnings Per Share Growth Rate during the Performance
               Period places the Company's performance higher than the ____th
               percentile. Attachment A provides a generic example of the
               operation of an award granted under this Award Agreement.

          6.   EARNINGS PER SHARE GROWTH RATE. "Earnings Per Share Growth Rate"
               for the Performance Period is the compounded annual-growth rate
               (CAGR) of a company's earnings per share from continuing
               operations, on a fully diluted basis, during the Performance
               Period; provided, however, that for purposes of calculating the
               Company's Earnings Per Share Growth Rate, SunCor Development
               Company's earnings from discontinued operations will be
               considered earnings from continuing operations for each fiscal
               year during the Performance Period. Only those companies which
               were in the S&P Electric

Performance Share Agreement

               Utility Index at both the beginning and the ending of the
               Performance Period will be considered. The Earnings Per Share
               Growth Rate of the companies in the S&P Electric Utilities Index
               will be determined using the S&P Compustat system. If the S&P
               Compustat system is no longer in use, the Committee shall replace
               it with the most comparable third party data system then in use.
               If the S&P Electric Utilities Index is discontinued, the S&P
               comparable replacement index for the sector will be used for
               computing Earnings Per Share Growth Rate. If S&P no longer
               computes an index for the electric utility sector, the Committee
               shall select the most comparable index then in use for the sector
               comparison. In addition, if the sector comparison is no longer
               representative of the Company's industry or business, the
               Committee shall replace the index with the most representative
               index then in use. Once the CAGR of the Company and all relevant
               companies in the S&P Electric Utility Index have been determined,
               the member companies will be ranked from greatest to least CAGR.
               Percentiles will be calculated based on a company's relative
               ranking. For example, company 1 out of 26 companies is given a
               percentile of 96.2% (1.0 - 1/26). Percentiles will be carried out
               to one (1) decimal place. If the Company is not in the S&P
               Electric Utility Index, then its percentile will be interpolated
               between the companies listed in the relative ranking. These
               calculations will be verified by the Company's internal auditors.

          7.   TERMINATION OF AWARD. This Award Agreement will terminate and be
               of no further force or effect on the date that Employee is no
               longer actively employed by the Company or any of its
               subsidiaries, whether due to voluntary or involuntary
               termination, death, retirement, disability, or otherwise. Subject
               to Section 4, Employee will, however, be entitled to receive any
               Common Stock and dividend equivalents payable under Section 4 of
               this Award Agreement if Employee's employment terminates after
               the Performance Period but before Employee's receipt of such
               Common Stock and dividend equivalents. For avoidance of doubt, no
               acceleration of Performance Shares or the Performance Period will
               occur on a change of control of the Company.

          8.   TAX WITHHOLDING. Employee must pay, or make arrangements
               acceptable to the Company for the payment of any and all federal,
               state, and local income and payroll tax withholding that in the
               opinion of the Company is required by law. Unless Employee
               satisfies any such tax withholding obligation by paying the
               amount in cash or by check, the Company will withhold shares of
               Common Stock having a Fair Market Value on the date of
               withholding sufficient to cover the withholding obligation.

          9.   NON-TRANSFERABILITY. Neither this award nor any rights under this
               Award Agreement may be assigned, transferred, or in any manner
               encumbered except by will or the laws of descent and
               distribution, and any attempted assignment, transfer, mortgage,
               pledge or encumbrance except as herein authorized, will be void
               and of no effect.

          10.  DEFINITIONS: COPY OF PLAN AND PLAN PROSPECTUS. To the extent not
               specifically defined in this Award Agreement, all capitalized
               terms used in this Award Agreement will have the same meanings
               ascribed to them in the Plan. By signing this Award Agreement,
               Employee acknowledges receipt of a copy of the Plan and the
               related Plan Prospectus.

          11.  CHOICE OF LAW. This Agreement will be governed by the laws of the
               State of Arizona, excluding any conflicts or choice of law rule
               or principle that might otherwise refer construction or
               interpretation of this Agreement to another jurisdiction.
