                            EL PASO ELECTRIC COMPANY
                           CHANGE OF CONTROL AGREEMENT
                             FOR EXECUTIVE OFFICERS

                  AGREEMENT by and between El Paso Electric Company, a Texas
corporation (the "Company"), and [Name] (the "Executive"), dated as of the 7th
day of February, 2002.

                               W I T N E S S E T H

                  WHEREAS, the Executive currently serves as a key employee of
the Company and his or her services and knowledge are valuable to the Company in
connection with the management of the Company; and

                  WHEREAS, the Board of Directors of the Company (the "Board")
has determined that it is in the best interests of the Company and its
stockholders to secure the Executive's continued services and to ensure the
Executive's continued dedication and objectivity in the event of any threat or
occurrence of, or negotiation or other action that could lead to, or create the
possibility of, a Change in Control (as defined in Attachment 1) of the Company,
without concern as to whether the Executive might be hindered or distracted by
personal uncertainties and risks created by any such possible Change in Control,
and to encourage the Executive's full attention and dedication to the Company,
the Board has authorized the Company to enter into this Agreement.

                  NOW, THEREFORE, for and in consideration of the premises and
the mutual covenants and agreements herein contained, the Company and the
Executive hereby agree as follows:

         1. Employment Period. (a) The Company hereby agrees to employ the
Executive and the Executive hereby agrees to accept employment with and remain
in the employment of the Company, subject to the terms and conditions of this
Agreement, for the period commencing upon the occurrence of a Change in Control
and ending on the second anniversary thereof, or such later date as may be
mutually agreed upon by the Company and the Executive. Notwithstanding the
foregoing, the Executive's employment hereunder may be earlier terminated,
subject to Section 4 of this Agreement. The period of time between the
commencement and the termination of the Executive's employment hereunder shall
be referred to herein as the "Employment Period."

         (b) Prior to the occurrence of a Change in Control, the Executive's
employment by the Company shall be deemed at will (or shall be governed by any
current contract of

                                       1

<PAGE>

employment), and this Agreement shall not confer upon the Executive any right to
continued employment by the Company in his or her current position or otherwise
nor affect in any manner the right of the Company to change the Executive's
duties and responsibilities in any manner, or to reduce Executive's compensation
or terminate the employment of the Executive at any time prior to the occurrence
of a Change in Control and in connection therewith to cancel this Agreement. In
particular, the Executive shall not have any rights under this Agreement for any
such change, reduction or termination of employment or of this Agreement "in
anticipation of " any "change of control" that shall occur prior to the
occurrence of a Change in Control.

         2.   Terms of Employment. (a) Position and Duties. (i) During the
Employment Period, (A) the Executive shall serve as [Business] of the Company or
his or her then current position at the time of a Change of Control (or the
equivalent position in the division, subsidiary or other portion of any
post-merger or post-acquisition successor that is operationally responsible for
the electric business conducted by the Company prior to the merger or
acquisition), with such authority, duties and responsibilities as are
commensurate with such position and as may be consistent with such position as
may be assigned to him or her by the Board and (B) the Executive's services
shall be performed at the Company's offices in El Paso, Texas. Notwithstanding
the foregoing, the Company and the Executive may mutually agree to such changes
in the Executive's position, reporting or location of employment as are in the
best interest of the Company without violating the provisions of this paragraph.

         (ii) During the Employment Period, and excluding any periods of
vacation and sick leave to which the Executive is entitled, the Executive agrees
to devote substantially all of his or her attention and time during normal
business hours to the business and affairs of the Company and, to the extent
necessary to discharge the responsibilities assigned to the Executive hereunder,
to use the Executive's best efforts to perform faithfully and efficiently such
responsibilities. During the Employment Period, it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements, or
teach at educational institutions, and (C) manage personal investments, so long
as such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement.

         (b)  Compensation. (i) Base Salary. During the Employment Period, the
Executive shall receive an annual base salary ("Annual Base Salary"), payable
biweekly, at least equal to the annual base salary paid or payable, including
any base salary which has been earned but deferred, to the Executive by the
Company in respect of the twelve-month period immediately preceding the
occurrence of a Change in Control. During the Employment Period, the Annual Base
Salary shall be reviewed no more than 12 months after the last salary increase
awarded to the Executive prior to the occurrence of a Change in Control and
thereafter at least annually. Any increase in Annual Base Salary shall not

                                       2

<PAGE>

serve to limit or reduce any other obligation to the Executive under this
Agreement. Annual Base Salary shall not be reduced after any such increase and
the term Annual Base Salary shall refer to Annual Base Salary as so increased.
As used in this Agreement, the term "affiliated companies" shall include any
company controlled by, controlling or under common control with the Company.

         (ii)  Annual Bonus. In addition to Annual Base Salary, for each fiscal
year ending during the Employment Period the Executive shall be eligible, based
upon the Executive's achievement of performance goals, and the Company's
achievement of financial and other operating goals, in each case set by the
Compensation Committee of the Board, in consultation with the Executive, at
levels substantially consistent with past practice, during such fiscal year, to
receive a bonus (the "Annual Bonus") at a target level of not less than 17% of
the Annual Base Salary (the "Target Bonus Amount") with the opportunity,
substantially consistent with past practice, to earn in excess of such amount
based upon the attainment of agreed upon performance goals. Each such Annual
Bonus shall be paid no later than the last business day of the third month of
the fiscal year next following the fiscal year for which the Annual Bonus is
awarded (the "Last Payment Date").

         (iii) Long-Term Incentive Compensation. During the Employment Period,
the Executive shall be entitled to participate in all long-term incentive plans,
practices, policies and programs applicable generally to other peer executives
of the Company.

         (iv)  Savings and Retirement Plans. During the Employment Period, the
Executive shall be entitled to participate in all savings and retirement plans,
practices, policies and programs on a basis no less favorable than that
generally applicable to peer executives of the Company.

         (v)   Welfare Benefit Plans. During the Employment Period, the
Executive and/or the Executive's dependents, as the case may be, shall be
eligible for participation in and shall receive all benefits under welfare
benefit plans, practices, policies and programs provided by the Company on a
basis no less favorable than that generally applicable to peer executives of the
Company.

         (vi)  Expenses. During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the Company's policies.

         (vii) Vacation. During the Employment Period, the Executive shall be
entitled to paid vacation in accordance with the plans, policies, programs and
practices of the Company on a basis no less favorable than that generally
applicable to peer executives of the Company but, in any event, shall be
entitled to no less than four weeks of vacation per year during the Employment
Period.

                                       3

         3.  Termination of Employment. (a) Death or Disability. The Executive's
employment shall terminate automatically upon the Executive's death during the
Employment Period. If the Disability of the Executive occurs during the
Employment Period pursuant to the definition of Disability set forth below, the
Company may give the Executive written notice, in accordance with Section 10(b)
of this Agreement, of its intention to terminate the Executive's employment. In
such event, the Executive's employment with the Company shall terminate
effective on the 60th day after receipt of such notice by the Executive (the
"Disability Effective Date"); provided that, within the 60 days after such
receipt, the Executive shall not have returned to substantially full time
performance of the Executive's duties. For purposes of this Agreement,
"Disability" shall mean the absence of the Executive from the performance of the
Executive's duties with the Company on a full time basis for an aggregate of 120
out of any 180 consecutive business days as a result of incapacity due to mental
or physical illness which is determined to be total and permanent by an
independent physician selected by the Company or its insurers and reasonably
acceptable to the Executive or the Executive's legal representative.

         (b) Cause. The Company may terminate the Executive's employment during
the Employment Period for Cause. For purposes of this Agreement, "Cause" shall
mean the willful and continued failure by the Executive to perform his or her
duties, or the engaging by the Executive in illegal conduct or misconduct which
is materially injurious to the Company. The cessation of employment of the
Executive shall not be deemed to be for Cause unless and until there shall have
been delivered to the Executive a copy of a resolution duly adopted by the
affirmative vote of not less than three-quarters of the entire membership of the
Board at a meeting of the Board called and held for such purpose (after
reasonable notice is provided to the Executive and the Executive is given an
opportunity, together with counsel, to be heard before the Board) finding that,
in the good faith opinion of the Board, the Executive is guilty of the conduct
described above, and specifying the particulars thereof in detail.

         (c) Good Reason.  The  Executive's  employment  may be  terminated  by
the  Executive  for Good  Reason.  For purposes of this Agreement, "Good Reason"
shall mean:

         (i) the assignment to the Executive of any duties inconsistent with the
Executive's position (including status, offices, titles and reporting
requirements), authority, duties or responsibilities set forth in Section 2(a)
of this Agreement, or any other action by the Company which results in a
diminution in such position, authority, duties or responsibilities, excluding
for these purposes (A) assignment to a comparable position and duties in the
division, subsidiary or other portion of any post-merger or post-acquisition
successor that is operationally responsible for the electric business conducted
by the Company prior to the merger or acquisition, (B) an isolated and
insubstantial action not taken in bad faith and which is remedied by the Company
promptly after receipt of notice thereof given by the Executive, and (C) any
action to which the Executive has given his or her written consent;

                                       4

<PAGE>

     (ii)  any failure by the Company to comply with any of the provisions of
Section 2(b) of this Agreement, other than an isolated and insubstantial failure
not occurring in bad faith and which is remedied by the Company promptly after
receipt of notice thereof given by the Executive;

     (iii) the Company's requiring the Executive without the Executive's written
consent to be based at any office or location located more than 100 miles from
the office or location provided in Section 2(a)(i)(B) hereof or the Company's
requiring the Executive to travel on Company business to a substantially greater
extent than required immediately prior to the Effective Date;

     (iv)  any failure by the Company to comply with and satisfy Section 9(c) of
this Agreement; or

     (v)   the Company's purported termination of Agreement other than in
accordance with its terms.

     (d)   Notice of Termination. Any termination by the Company for Cause, or
by the Executive for Good Reason, shall be communicated by Notice of Termination
to the other party hereto given in accordance with Section 10(b) of this
Agreement. In the case of a Good Reason termination, such Notice of Termination
shall be given within 90 days of the occurrence of the event that provides the
basis for the termination as a condition of such claim being treated as a Good
Reason termination hereunder. For purposes of this Agreement, a "Notice of
Termination" means a written notice which (i) indicates the specific termination
provision in this Agreement relied upon, (ii) to the extent applicable, sets
forth in reasonable detail the facts and circumstances claimed to provide a
basis for termination of the Executive's employment under the provision so
indicated and (iii) if the Date of Termination (as defined below) is other than
the date of receipt of such notice, specifies the termination date (which date
shall be not more than 30 days after the giving of such notice). The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company, respectively, hereunder or
preclude the Executive or the Company, respectively, from asserting such fact or
circumstance in enforcing the Executive's or the Company's rights hereunder.

     (e)   Date of Termination. "Date of Termination" means (i) if the
Executive's employment is terminated by the Company for Cause, or by the
Executive for any reason (including Good Reason), the date of receipt of the
Notice of Termination or any later date specified therein that is within 30 days
of such Notice, as the case may be, (ii) if the Executive's employment is
terminated by the Company other than for Cause or Disability, the Date of
Termination shall be the date on which the Company notifies the Executive of
such termination and (iii) if the Executive's employment is terminated by reason
of death or

                                       5

<PAGE>

Disability, the Date of Termination shall be the date of death of the Executive
or the Disability Effective Date, as the case may be.

     4.   Obligations of the Company upon Termination. (a) Good Reason; Other
than for Cause, Death or Disability. If, during the Employment Period, the
Company shall terminate the Executive's employment other than for Cause or
Disability or the Executive shall terminate employment for Good Reason:

     (i)  the Company shall pay to the Executive in a lump sum in cash within 30
days after the Date of Termination the aggregate of the following amounts:

     A.   the sum of (1) the Executive's Annual Base Salary through the Date of
Termination to the extent not theretofore paid; (2) the product of (x) higher of
the bonus paid to the Executive for the most recent full year prior to the Date
of Termination or the average of the past 3 years' bonuses (the "Highest Annual
Bonus") and (y) a fraction, the numerator of which is the number of days in the
current year through the Date of Termination, and the denominator of which is
365; and (3) any accrued vacation pay to the extent not theretofore paid (the
sum of the amounts described in clauses (1), (2), and (3) shall be hereinafter
referred to as the "Accrued Obligations");

     B.   the amount equal to the product of (1) 2.99 and (2) the sum of (x) the
Executive's Annual Base Salary and (y) the Highest Annual Bonus; and

     C.   the actuarial equivalent of the amounts by which the Executive's total
vested benefits under The El Paso Electric Company Retirement Plan (or any
successor plan put into effect prior to a Change in Control), computed as if
Executive had three additional years of benefit accrual service, exceed the
Executive's actual pension benefits. For this computation, the Executive's final
average salary shall be deemed to be the Executive's annual base compensation in
effect immediately prior to the time a Notice of Termination is given and the
benefit and accrual formulas and actuarial assumptions shall be no less
favorable than those in effect at such time; "base compensation" shall include
any amounts deducted by the Company for Executive's account under any agreement
with the Company or Section 125 and 401(k) of the Internal Revenue Code of 1986,
as amended (the "Code").

     (ii) for two years after the Executive's Date of Termination, or such
longer period as may be provided by the terms of the appropriate plan, program,
practice or policy, the Company shall continue the medical, long-term
disability, dental, accidental death and dismemberment and life insurance
benefits to the Executive and/or the Executive's dependents at least equal to
those which would have been provided to them in accordance with the plans,
programs, practices and policies in effect under Section 2(b)(v) of this
Agreement (the "Continuing Benefit Plans") as if the Executive's employment had
not been terminated (either by permitting the Executive and/or the Executive's
dependents to

                                       6

<PAGE>

participate in the Continuing Benefit Plans, or by providing the Executive
and/or the Executive's dependents with equivalent benefits outside the
Continuing Benefit Plans, as the Company may elect, so long as the net after-tax
benefit to them is the same as if the Executive had remained an employee of the
Company participating in the Continuing Benefit Plans); provided, however, that
if the Executive becomes reemployed with another employer and is eligible to
receive medical, long-term disability, dental, accidental death and
dismemberment or life insurance benefits under another employer-provided plan,
the medical, long-term disability, dental, accidental death and dismemberment
and life insurance benefits described herein shall be secondary to those
provided under such other plan during such applicable period of eligibility. For
purposes of determining eligibility (but not the time of commencement of
benefits) of the Executive for retiree benefits pursuant to the Continuing
Benefit Plans and any other welfare benefit plans, practices, policies and
programs provided by the Company and its affiliated companies, the Executive
shall be considered to have remained employed until two years after the Date of
Termination and to have retired on the last day of such period;

     (iii) for one year after the Executive's Date of Termination, the Company
shall provide outplacement services for the Executive; and

     (iv)  to the extent not theretofore paid or provided, the Company shall
timely pay or provide to the Executive any other amounts or benefits required to
be paid or provided or which the Executive is eligible to receive under any
plan, program, policy or practice or contract or agreement of the Company, as of
the Date of Termination (such other amounts are benefits shall be thereinafter
referred to as the "Other Benefits").

     (b)   Death. If the Executive's employment is terminated by reason of the
Executive's death during the Employment Period, this Agreement shall terminate
without further obligation to the Executive's Legal Representatives under this
Agreement, other than for payment of Accrued Obligations and the timely payment
or provision of Other Benefits. Accrued Obligations shall be paid to the
Executive's estate or beneficiary, as applicable, in a lump sum in cash within
30 days of the Date of Termination. The term Other Benefits as utilized in this
Section 4(b) shall include death benefits as in effect on the date of the
Executive's death.

     (c)   Disability. If the Executive's employment is terminated by reason
of the Executive's Disability during the Employment Period, this Agreement shall
terminate without further obligation to the Executive, other than for payment of
Accrued Obligations and the timely payment or provision of Other Benefits.
Accrued Obligations shall be paid to the Executive in a lump sum in cash within
30 days of the Date of Termination.

     (d)   Cause; Other than for Good Reason. If the Executive's employment
shall be terminated for Cause or the Executive terminates his or her employment
without Good Reason during the Employment Period, this Agreement shall terminate
without further

                                        7

<PAGE>

obligation to the Executive other than the obligation to pay to the Executive
(x) his or her Annual Base Salary through the Date of Termination and (y) Other
Benefits, in each case to the extent theretofore unpaid.

     5. Non-exclusivity of Rights. 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 any of its affiliated companies
and for which the Executive may qualify, nor, subject to Section 10(f), shall
anything herein limit or otherwise affect such rights as the Executive may have
under any contract or agreement with the Company or any of its affiliated
Companies. Any rights that are vested and any benefits that the Executive is
otherwise entitled to receive under any plan, policy, practice or program of or
any contract or agreement with the Company or any of its affiliated companies at
or subsequent to the Date of Termination shall be payable in accordance with
such plan, policy, practice or program or contract or agreement except as
explicitly modified by this Agreement.

     6. Full Settlement. In no event shall the Executive be obligated to seek
other employment or take any other action by way of mitigation of the amounts
payable to the Executive under any of the provisions of this Agreement and,
except as provided in section 4(a)(ii) of this Agreement, such amounts shall not
be reduced whether or not the Executive obtains other employment. The Company
agrees to pay as incurred, to the full extent permitted by law, all legal fees
and expenses which the Executive may reasonably incur as a result of any contest
regardless of the outcome thereof by the Company, the Executive or others of the
validity or enforceability of, liability under, any provision of this Agreement
of any guarantee of performance thereof including as a result of any contest by
the Executive about the amount of any payment pursuant to this Agreement;
provided, however, that the foregoing shall not apply in connection with any
such contest in which the finder of fact determines that the contest is
frivolous or was brought by the Executive in bad faith.

     7. Gross-Up Provision. (a) If the payments provided by Section 4(a)(i)-(iv)
hereof (the "Agreement Payments") become subject to the tax (the "Excise Tax")
imposed by Section 4999 of the Code as in effect on the date of this Agreement
(or any similar tax), Executive will be responsible for the Excise Tax and the
Company will not pay Executive an additional amount (the "Gross-up Payment").
If, however, the "Agreement Payments" become subject to the Excise Tax (or any
similar tax) by virtue of changes in the Code which occur after the date of this
Agreement, the Company shall pay to Executive at the time specified in Section
7(b) below a "Gross-up Payment" such that the net amount retained by Executive,
after deduction of any Excise Tax on the Total Payments (as hereinafter
defined), and any federal, state and local income tax and Excise Tax upon the
Gross-up Payment provided for by this subsection (a) shall be equal to what the
Total Payments would have been had such changes in the Code not occurred.

                                       8

<PAGE>

         For purposes of determining whether any of the Agreement Payments will
be subject to the Excise Tax and the amount of such Excise Tax, (i) any other
payments or benefits received or to be received by Executive in connection with
a Change in Control or Executive's termination of employment (under this
Agreement or any other agreement with the Company or any person whose actions
result in a Change of Control or any person affiliated with the Company) (which,
together with the Agreement Payments, shall constitute the "Total Payments")
shall be treated as "parachute payments" within the meaning of Section
280G(b)(2) of the Code, and all "excess parachute payments" within the meaning
of Section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax,
unless in the opinion of tax counsel selected by the Company's independent
auditors such other payments or benefits (in whole or in part) are not subject
to the Excise Tax, (ii) the amount of the Total Payments which shall be treated
as subject to the Excise Tax shall be equal to the lesser of (A) the Total
Payments or (B) the amount of excess parachute payments within the meaning of
Section 280G(b)(1) of the Code (after applying clause (i), above), and (iii) the
value of any non-cash benefits or any deferred payment or benefit shall be
determined by the Company's independent auditors in accordance with the
principles of Sections 280G(d)(3) and (4) of the Code.

         For purposes of determining the Gross-up Payment, Executive shall be
deemed to pay federal, state, and local income taxes at the highest applicable
marginal rate for the calendar year in which the Gross-up Payment is to be made
net of the maximum reduction in federal income taxes which could be obtained
from deduction of such state and local taxes. If the Excise Tax is finally
determined to be less than the amount taken into account at the time the
Gross-up Payment is made, Executive shall repay the portion attributable to such
reduction (plus the portion of the Gross-up Payment attributable to a reduction
in Excise Tax and/or a federal and state and local income tax deduction), plus
interest on the amount of such repayment at the rate provided in Section
1274(b)(2)(B)of the Code. If the Excise Tax is later determined to exceed the
amount taken into account at the time the Gross-up Payment is made, the Company
shall make an additional gross-up payment (plus any interest payable with
respect to such excess at the rate provided in Section 1274(b)(2)(B) of the
Code) when such excess is finally determined.

         (b) The Gross-up Payment or portion thereof provided for in subsection
(a) above shall be paid not later than the thirtieth day following payment of
any amounts under Section 4(a)(i); provided, however, that if the amount of such
Gross-up Payment or portion thereof cannot be finally determined on or before
such day, the Company shall pay to Executive on such day an estimate, as
determined in good faith by the Company, of the minimum amount of such payments
and shall pay the remainder of such payments (together with interest at the rate
provided in Section 1274(b)(2)(B) of the Code) as soon as the amount thereof can
be determined, but in no event later than the forty-fifth day after payment of
any amounts under Section 4(a)(i). If the amount of the estimated payments
exceeds the amount subsequently determined to have been due, such excess shall
constitute a loan by the Company to the Executive, payable on the fifth day
after demand

                                       9

<PAGE>

by the Company (together with interest at the rate provided for in Section
1274(b)(2)(B) of the Code).

         (c) In the event it shall be determined by the Company's independent
auditors that the Agreement Payments would subject the Executive to the Excise
Tax, it shall also be determined whether a reduction in the Agreement Payments
would result in an after-tax amount with a greater net present value than would
occur without such reduction. If so, the Agreement Payments shall be reduced by
the minimum amount necessary to obtain such result.

         If such reduced payments incorrectly result in an overpayment or
underpayment to Executive, the underpayment shall be promptly paid to Executive
and, if an overpayment shall have occurred, it shall be treated for all purposes
as a loan to Executive by the Company which Executive shall repay on the fifth
day after demand by the Company, in each case together with interest at the
applicable rate provided for in Section 1274(b)(2)(B) of the Code.

         8. (a) Confidential Information. The Executive shall hold in a
fiduciary capacity for the benefit of the Company all secret or confidential
information, knowledge or data relating to the Company or any of its affiliated
companies, and their respective businesses, which shall have been obtained by
the Executive during the Executive's employment by the Company or any of its
affiliated companies and which shall not be or become public knowledge (other
than by acts by the Executive or representatives of the Executive in violation
of this Agreement). The Executive shall not, at any time during his or her
employment with the Company or at any time thereafter, for any reason, in any
fashion, form or manner, either directly or indirectly, communicate, divulge,
copy or permit to be copied (without the prior written consent of the Company or
as may otherwise be required by law or legal process or in order to enforce his
or her rights under this Agreement or as necessary to defend himself or herself
against a claim asserted directly or indirectly by the Company or any of its
affiliated companies) any secret or confidential information, knowledge or data
relating to the Company or any of its affiliated companies, and their respective
businesses, in any manner whatsoever, that is not otherwise publicly available
to, or for the benefit of, any person, firm, corporation or other entity, other
than the Company and those designated by it or in the course of his or her
employment with the Company and its affiliated companies. As used herein, the
term "all secret or confidential information, knowledge or data relating to the
Company or any of its affiliated companies, and their respective businesses"
shall include, without limitation, the Company's plans, strategies, proposals to
potential customers and/or partners, costs, prices, proprietary systems for
buying and selling, client and customer lists, identity of prospects,
proprietary computer programs, policy or procedure-manuals, proprietary training
and recruiting procedures, proprietary accounting procedures, and the status and
contents of the Company's contracts with its suppliers, clients, customers or
prospects. The Executive

                                       10

<PAGE>

further agrees to maintain in confidence any confidential information of third
parties received as a result of his or her employment with the Company.

         (b) Enforcement. In the event of a breach or threatened breach of this
Section 8, the Executive agrees that the Company shall be entitled, in addition
to any other remedies available to it to specific performance and injunctive
relief in a court of appropriate jurisdiction to remedy any such breach or
threatened breach, and the Executive acknowledges that damages would be
inadequate and insufficient. In no event shall an asserted violation of the
provisions of this Section 8 constitute a basis for deferring or withholding any
amounts otherwise payable to the Executive under this Agreement.

all judgments, fines, penalties, excise taxes, amounts paid in settlement,
losses, expenses, costs, liabilities and legal fees if the Executive is made, or
threatened to be made a party to any threatened or pending or completed action,
suit, proceeding, whether civil, criminal, administrative or investigative,

          "Change in Control" shall mean:

          (1)  the acquisition by any individual, entity or group (a "Person"),
including any "person" within the meaning of Section 13(d) (3) or 14(d) (2) of

                                                     --------------------------
Securities"); excluding, however, the following: (A) any acquisition directly
----------
from the Company (excluding any acquisition resulting from the exercise of an
exercise, conversion or exchange privilege unless the security being so
exercised, converted or exchanged was acquired directly from the Company), (B)
any acquisition by the Company, (C) any acquisition by an employee benefit plan
(or related trust) sponsored or maintained by the Company or any corporation
controlled by the Company, or (D) any acquisition by any corporation pursuant to
a transaction which complies with clauses (i), (ii) and (iii) of subsection (3)

          (2)  individuals who, as of March 6, 2002, constitute the Board of

majority of the directors then comprising the Incumbent Board shall be deemed a
member of the Incumbent Board; and provided further, that any individual who was
initially elected as a director of the Company as a result of an actual or
threatened election contest, as such terms are used in Rule 14a-11 of Regulation
14A promulgated under the Exchange Act, or any other actual or threatened
solicitation of proxies or consents by or on behalf of any Person other than the
Board shall not be deemed a member of the Incumbent Board;

          (3)  approval by the stockholders of the Company of a reorganization,
merger or consolidation or sale or other disposition of all or substantially all

stock, and the combined voting power of the outstanding securities of such
corporation entitled to vote generally in the election of directors, as the case
may be, of the corporation resulting from such Corporate Transaction (including,
without limitation, a corporation which as a result of such transaction owns the
Company or all or substantially

                                       A-1

<PAGE>

all of the Company's assets either directly or indirectly) in substantially the
same proportions relative to each other as their ownership, immediately prior to

Outstanding Company Voting Securities, as the case may be, (ii) no Person (other
than: the Company; any employee benefit plan (or related trust) sponsored or
maintained by the Company or any corporation controlled by the Company; the
corporation resulting from such Corporate Transaction; and any Person which
beneficially owned, immediately prior to such Corporate Transaction, directly or
indirectly, 30% or more of the Outstanding Company Common Stock or the

shares of common stock of the corporation resulting from such Corporate
Transaction or the combined voting power of the outstanding securities of such

the same proportions as their ownership, immediately prior to such
reorganization, merger, consolidation or other transaction, of such Outstanding
Company Voting Securities.

2.       RECITALS
         --------
         This Agreement is made with reference to the following facts, among
         others:
         2.1      The Four Corners Participants, as defined in Section 4.21, are
                  owners of the 345-kV Switchyard, located near Farmington, New
                  Mexico;
         2.2      The Interconnection Participants, as defined in Section 4.28,
                  have upgraded the Shiprock-Four Corners Transmission Line for
                  operation at 345-kV and desire to relocate said transmission
                  line termination from the 230-kV Switchyard to the 345-kV
                  Switchyard pursuant to this Agreement;
         2.3      By resolution dated February 15, 1995, the E&O Committee
                  recommended approval of the relocation of the Four Corners'
                  termination of Western's Shiprock-Four Corners Transmission
                  Line from the 230-kV Switchyard to the 345-kV Switchyard,
                  subject to: i) the conclusion of negotiations between the Four
                  Corners Participants and the Interconnection Participants on
                  the terms and conditions for such terminal relocation, and

<PAGE>

                  ii) the execution of an interconnection agreement. In a
                  subsequent resolution dated August 18, 1999, the E&O Committee
                  reaffirmed its resolution of the relocation of Western's
                  Shiprock-Four Corners Transmission Line from the 230-kV
                  Switchyard to the 345-kV Switchyard at Four Corners Project.
         2.4      The Parties anticipate that the interconnection and operation
                  of the Shiprock-Four Corners Transmission Line at 345-kV will
                  provide mutual benefits, which may include: 1) improvements in
                  reliability, 2) increases in both scheduling and transfer
                  capability, 3) a means of furnishing emergency assistance and
                  4) opportunities for increases in market sales, purchases,
                  and/or exchanges of power and energy. Consequently, the Four
                  Corners Participants are willing to permit the relocation of
                  the Shiprock-Four Corners Transmission Line termination from
                  the 230-kV Switchyard to the 345-kV Switchyard in accordance
                  with the terms and conditions contained in this Agreement.
         2.5      APS acts on behalf of itself and as Operating Agent on behalf
                  of the Four Corners Participants under the Operating
                  Agreement. The Interconnection Participants desire that APS
                  design, construct, own, operate, and maintain the
                  Interconnection Facilities.
         2.6      The Parties understand that the Operating Agent may join an
                  independent system operator (ISO) or regional transmission
                  organization (RTO) under FERC jurisdiction. In the event the
                  Operating Agent either joins or is required to conform to
                  protocols of an ISO/RTO, the Parties agree that the Operating
                  Agent may propose contractual language changes necessary to
                  conform to the terms and conditions required by FERC's
                  approval of the ISO/RTO in the form of an amendment to this
                  agreement.
         2.7      This Agreement does not provide a right to transmit energy
                  other than across the Enlarged Switchyard buses except and
                  only to the extent that all necessary arrangements for
                  transmission rights and service are in place. Nothing in this
                  Agreement shall be deemed either expressly or implicitly to
                  obligate any Party to provide or make available to the
                  Interconnection Participants any transmission services,
                  control area services, distribution services, or ancillary
                  services for the transport of energy and the Four Corners
                  Participants make no representation in this Agreement
                  regarding the availability of such services. This Agreement
                  provides no obligation for any Party to purchase, sell,
                  transmit, or otherwise provide any rights other than the right
                  to interconnect.

                  the Operating Agreement, or use of the existing electric
                  transmission lines and switchyard facilities connected thereto
                  as shown on Exhibit 1.
         15.2     Curtailment
                  -----------
                  15.2.1   If at any time the facilities described in Section 24
                           of the Operating Agreement, the Switchyard Addition,
                           or any electric transmission line or switchyard
                           facility connected thereto (all as shown on Exhibit
                           1, Enlarged Switchyard Diagram, attached hereto)
                           cannot accommodate the power and energy schedules
                           then existing due to adverse occurrences such as
                           unscheduled power flow, operating emergencies, or
                           abnormal operating conditions (collectively and
                           individually, "Overload Conditions"), Operating Agent
                           shall take whatever action it deems appropriate to
                           relieve such Overload Conditions consistent with Good
                           Utility Practice.
                  15.2.2   If actions taken by the Operating Agent pursuant to
                           Section 15.2.1 are not sufficient to relieve Overload
                           Conditions, then schedules of power and energy,
                           including those of Interconnection Participants,
                           which in the sole judgment of Operating Agent
                           contribute to such Overload Conditions, shall be
                           curtailed upon the request of Operating Agent until
                           such Overload Conditions no longer exist. The Parties
                           shall share the remaining transmission capacity in
                           proportion to each Party's entitlement in the
                           transmission path requiring curtailment. Operating
                           Agent shall limit the request for curtailment to an
                           amount sufficient to relieve the Overload Conditions.
         15.3     Reactive Power - Except as the Parties may otherwise agree,
                  --------------
                  none of the Parties shall be obligated to provide or exchange
                  reactive power with the other Parties. Each Party shall
                  cooperate with the other Parties to minimize the unintended
                  flow of reactive power between their electric utility systems.

16.      OPERATING EMERGENCY

                  Switchyard and/or Switchyard Addition to substantially the
                  same general condition as existed prior to the Operating
                  Emergency. Each Interconnection Participant shall be obligated
                  to pay its proportionate share, as determined in accordance
                  with Exhibit 6, % - Responsibility For Costs, attached hereto,

                               iv)    If any payment of Other Taxes made to a
                                      Four Corners Participant is found to be
                                      excessive or illegal by the appropriate
                                      jurisdictional authority, such excessive

26.      UNCONTROLLABLE FORCES
         ---------------------
         No Party shall be considered to be in default in the performance of its
         obligations hereunder (other than the obligation of said Party to make
         payment of invoices rendered hereunder) when a delay in or failure of
         performance shall be due to an Uncontrollable Force. The term
         "Uncontrollable Force" shall mean any cause beyond the reasonable
         control of a Party, including but not restricted to failure of or
         threat of failure of facilities, flood, earthquake, storm, fire,

         imposed by governmental or lawfully established authority, restraint by

         such Party could not reasonably have been expected to avoid and which
         by exercise of due diligence it shall be unable to overcome. Nothing
         contained herein shall be construed so as to require a Party to settle
         any strike or labor dispute in which it may be involved. Any Party
         rendered unable to fulfill any of its obligations hereunder by reason
         of an Uncontrollable Force shall give prompt written notice of such
         fact to the other Parties and shall exercise due diligence to remove
         such inability with all reasonable dispatch.

         shall ever be construed to create an association, joint venture, trust,
         or partnership, or to impose an association, joint venture, trust or
         partnership covenant, obligation, or liability on or with regard to any
         one or more of the Parties. Each Party shall be individually
         responsible for its own covenants, obligations, and liabilities as
         herein provided. No Party or group of Parties shall be under the
         control of nor shall be deemed to control any other Party or the

         power to bind any other Party without its express written consent,

                           calendar days after receiving written notice of
                           default of Section 30.2, Performance Default, hereof,
                           the defaulting Interconnection Participant does not
                           cure the default, the non-defaulting Interconnection
                           Participants shall remedy such default either by
                           advancing the necessary funds and/or rendering the
                           necessary service, with each non-defaulting

                           remedy an equal share of the payment due and owing,
                           or, as otherwise agreed, to cover the default.
                  30.4.2   The defaulting Interconnection Participant shall pay
                           promptly upon demand to each non-defaulting

                           and/or the reasonable equivalent in money of
                           non-monetary performance, if any, made by such
                           non-defaulting Interconnection Participant to cure
                           any default by the defaulting Interconnection
                           Participant together with interest on such money
                           and/or the costs of non-monetary performance at the
                           rate of ten percent (10 %) per annum or the maximum
                           rate of interest legally chargeable, whichever is the
                           lesser, from the date of the expenditure of such
                           money and/or the date of completion of such
                           non-monetary performance by each such non-defaulting
                           Interconnection Participant to the date of such
                           reimbursement by the defaulting Interconnection
                           Participant.
                  30.4.3   In the event that one or more Interconnection
                           Participants are in default under this Agreement and
                           the Operating Agent is not reimbursed as provided for
                           in Section 30.4.1 herein, the Operating Agent shall,
                           unless otherwise directed by the E&O Committee: i)
                           discontinue any of the services provided or made
                           available hereunder to such defaulting
                           Interconnection Participant; ii) suspend any right
                           granted to such Interconnected Participant pursuant
                           to Section 15, Operating Principles, hereof;  iii)
                           refuse to resume any such discontinued service and to
                           restore any such suspended right until such default
                           is cured; and iv) the Operating Agent may, as
                           directed by the E&O Committee and upon notice to the

                                      31

<PAGE>

                           Interconnection Participants, file a notice of
                           termination with FERC. Such discontinuance of
                           service or suspension of rights shall not relieve
                           such Interconnection Participant of any of its duties
                           or obligations under this Agreement.
                  30.4.4   Any default of the Operating Agent or a Four Corners
                           Participant to perform any obligation or duty owed
                           hereunder shall be deemed to be a default under the
                           Operating Agreement. If such default involves an
                           Interconnection Participant, such Interconnection
                           Participant shall have the right to give written
                           notice of such default to Operating Agent, to each
                           Party, and to each member of the E&O Committee. Such
                           notice of default given to Operating Agent by any
                           Party pursuant to Section 30.2, Performance Default,
                           hereof shall include a statement of the reasons, in
                           such Party's view, that the Operating Agent or Four
                           Corners Participant is in breach of this Agreement
                           and such notice shall be deemed a notice given under
                           Article 28 of the Operating Agreement.

31.      ARBITRATION
         -----------
         The Parties shall make best efforts to settle all disputes arising
         under this Agreement in the normal course of business and without
         recourse to either arbitration or litigation. However, should the
         Parties involved in a dispute agree that the dispute be submitted to
         arbitration, the following shall apply.
         31.1     Any arbitration initiated under this Agreement shall be
                  conducted before a single neutral arbitrator appointed by the
                  Parties. If the Parties fail to agree upon a single arbitrator
                  within ten (10) days of the referral of the dispute to
                  arbitration, each side of the dispute shall choose one
                  arbitrator who shall sit on a three-member arbitration panel.
                  The arbitrators so chosen shall within twenty (20) days select
                  a third arbitrator to chair the arbitration panel. The
                  arbitrators selected shall be knowledgeable in electric
                  utility matters including electric transmission and bulk power
                  issues, WSCC planning and operating criteria and policies, and
                  have no current or past substantial business or financial
                  relationships with any Party to the arbitration, except prior
                  arbitration. Any arbitration shall commence within ninety (90)
                  days of the demand for submission to arbitration.
         31.2     The arbitrator(s) shall have the discretion to establish a
                  discovery and hearing schedule and procedures for arbitration,
                  provided, that the arbitrator(s) adhere, as much as possible,
                  to the rules and practices of the American Arbitration
                  Association. The arbitrator(s) may conduct the arbitration
                  based solely upon the written submittal from the Party(ies) on
                  each

                                      32

<PAGE>

                  side of the dispute, which submittals may include a statement
                  of position, an accounting of costs incurred in attempting to
                  remedy an alleged default, and a proposed remedy or action.
                  Within five (5) calendar days after the conclusion of the
                  arbitration hearing, both sides to a dispute shall submit a
                  final proposed arbitration award and the arbitrator(s) shall
                  adopt in full one of the two proposed awards.
         31.3     Unless otherwise agreed, the arbitrator(s) shall render a
                  decision within forty- five (45) days of concluding the
                  arbitration hearing and shall notify the Parties in writing of
                  such decision and the reasons therefor. The arbitrator(s)
                  shall be authorized to interpret and apply the terms of this
                  Agreement but shall have no power to modify or change any of
                  the terms. The decision of the arbitrator(s) shall be final
                  and binding upon the Parties, and judgment on the award may be
                  entered in any court having jurisdiction. The decision of the
                  arbitrator(s) may be appealed solely on the grounds that the
                  conduct of the arbitrator(s), or the decision itself, violated
                  the standards set forth in the Federal Arbitration Act and/or
                  the Administrative Dispute Resolution Act.
         31.4     Each Party to the dispute shall be responsible for its own
                  costs incurred during the arbitration process and for the
                  following costs if applicable: i) the cost of the arbitrator
                  chosen to sit on the three-member panel and one-half of the
                  cost of the third arbitrator chosen; or ii) one half the cost
                  of the single arbitrator jointly chosen by the Parties to the
                  dispute.

32.      NONDEDICATION OF FACILITIES
         ---------------------------
         The Parties do not intend to dedicate and nothing in this Agreement
         shall be construed as constituting a dedication by any Party of its

         the customers of any Party.

                           Party to unilaterally make application to FERC for a
                           change in rates, charges, terms, conditions,
                           classification of service, or any rule, regulation or

                  33.3.2   Nothing contained in this Agreement shall be
                           construed as affecting in any way the ability of any
                           Party receiving service hereunder to exercise its
                           rights under the Federal Power Act or any successor

                           %-RESPONSIBILITY FOR COSTS
                           --------------------------

Each Interconnection Participant's percent responsibility for costs and expenses
that are allocable, reasonable and allowable and allocated to it under this
Agreement shall be as follows: Western 50%, PSCO 25%, and Tri-State 25%.

Notes
-----
The following definitions are applicable to the costs as described above.
1.      Allowable:
        ---------
        A cost is allowable if it is determined to be reasonable, allocable, or
        allowable under this Agreement and the FERC Accounts and is pursuant to
        Standard Accounting Principles.

2.      Reasonable:
        ----------
        A cost is reasonable if, in its nature and amount, it does not exceed
        that which would be incurred by a prudent person in the conduct of
        business.

3.      Allocable:
        ----------
        A cost is allocable if it is assignable or chargeable to one or more
        costs objectives on the basis of relative benefits received or other
        equitable relationship. A cost is allocable if it is incurred
        specifically by the Operating Agent for the purpose of performing
        Operating Work under this Agreement. A cost may also be allocable if it
        benefits both the Agreement and other work, and can be distributed to
        them in reasonable proportion to the benefits received by them. A cost
        is also allocable if it is necessary to the overall operation of the
        Four Corners Switchyard as it relates to the Common Facilities or the
        Interconnection Facilities.

                         COST RESPONSIBILITY RATIO (CRR)
                         -------------------------------

The 1997 plan for the Enlarged Switchyard, as shown on Exhibit 1, provides for
ten (10) Functions: six (6) transmission lines, three (3) power transformer
banks, and one (1) power generating unit. A total of nine (9) Functions
currently exist in the Enlarged Switchyard and one (1) Function will be
installed hereunder for the use of the Interconnection Participants. The initial
computation of the Interconnection Participants' Cost Responsibility Ratio under
the aforementioned plan is as follows:

                                                  Y
               Cost Responsibility Ratio =   -----------
                                              X + Y + Z

      X =     Number of Functions for the Four Corners Participants
      Y =     Number of Functions for Interconnection Participants
      Z =     Number of Functions for Third Parties. (Presently, there are no
              Functions for third parties.)

    Then: Cost Responsibility Ratio = 1/(9+1+0) = 1/10 = 10.0%
