                              Clerical AGREEMENT

This agreement, made and entered into as of February 1, 1998, by and between
Nevada Power Company, a corporation, hereinafter referred to as the Company, and
Local Union No. 396 of the International Brotherhood of Electrical Workers, an
affiliate of the A.F.L./C.I.O., hereinafter referred to as the Union.

                                  WITNESSETH

Whereas, for the purpose of facilitating the peaceful adjustments of differences
that may arise from time to time between the parties hereto, and to promote
harmony and efficiency to the end that the Company, the Union and the general
public may mutually benefit.

Now therefore, in consideration of the provisions, covenants and conditions
herein contained, the parties hereto agree as follows, to-wit:

              Introduction/Continuity of Service/Non-Discrimination

1.1  INTRODUCTION: The Company, in Clark and Nye counties, in the state of
     Nevada, a public utility engaged in the service of generating, transmitting
     and distributing electric power and energy, hereby recognizes Local Union
     No. 396 of the International Brotherhood of Electrical Workers,
     A.F.L./C.I.O., as the exclusive bargaining agent for its employees who are
     employed in Customer Service, Energy Services, Major Customer Services (LGS
     Billing), Field Service, Meter Shop, Districts, Material/Warehousing,
     Reprographic Services and Mail Room/Receiving Departments excluding all
     supervisory, confidential and professional employees within the meaning of
     the National Labor Relations Act, such covered employees more specifically
     defined in Exhibit I (CLASSIFICATION DESCRIPTIONS), for the purpose of
     collective bargaining with respect to rates of pay, wages, hours of
     employment and other conditions of employment which may be subject to
     collective bargaining.

1.2  CONTINUITY OF SERVICE: It is mutually recognized that the interest of the
     Company, the Union and the welfare of the general public, requires the
     continuous rendering of service by the Company, and the parties agree that
     recognition of such obligations of continuous service is imposed upon both
     the Company and its employees.

                                    Page #3


     The Company, to facilitate the continuous performance of such service,
     agrees to meet with the Business Manager of the Union or his designated
     representative in reference to any matter within the scope of the
     Agreement, and agrees that it will cooperate with the Union in its efforts
     to promote harmony and efficiency among all of the employees of the
     Company.

     The Union agrees that the employees covered by this Agreement, will not be
     called upon or permitted to cease or abstain from the continuous
     performance of the duties pertaining to the positions held by them with the
     Company. The Company agrees to do nothing to provoke interruption of or to
     prevent such continuity of performance as required in the normal and usual
     operations of the Company's property. It is mutually agreed that any
     difference that may arise between the above parties shall be settled in the
     manner hereinafter provided.

     The Union agrees that the employees covered by this agreement will
     individually and collectively perform loyal and efficient work and service
     and that they will cooperate in promoting and advancing the welfare of the
     Company and the protection of its service to the public at all times.

     The Union agrees that there will be no strikes, stoppages of work or
     slowdowns of the Company's operations during the term of this Agreement,
     and the Company agrees that there will be no lockouts during the term of
     this Agreement.

1.3  NON-DISCRIMINATION: Neither the Company nor the Union will discriminate
     against any employee in the application of the terms of this agreement
     because of race, religion, sex, age, color, national origin, veteran
     status, disability or any other legally protected status. It is understood
     that job titles used in this agreement which indicate the male gender are
     not intended to restrict classifications to employees of the male gender.

1.4  LAWS: It is understood and agreed that if mandatory laws or government
     rules or regulations applicable to or in conflict with any of the
     provisions of this Agreement become effective and binding upon the parties,
     such conflicting provisions of this Agreement shall be subject to
     modification as required and the parties shall meet and confer to determine
     mutually agreeable language to conform to the laws, government rules and/or
     regulations.

     If laws, government rules and/or regulations hereafter enacted require
     changes in the structure and/or services provided by the Company, then the
     Company and Union will, upon mutual consent, reopen negotiations concerning
     the terms of this Agreement that are directly affected by the changes.

1.5  AMENDMENT: This Agreement shall be subject to amendment at any time by
     mutual consent of the parties. Such amendment must be written, state the
     effective date of the amendment, and be executed in the same manner as this
     Agreement.

2.1  UNION DUES: The Company shall deduct money from Union employees' wages and
     pay it to the proper officers of the Union, provided the employee who is a
     member of the Union individually and voluntarily authorized such deduction
     to be made. The form of the check-off authorization is attached to this
     Agreement as Exhibit III (CHECK OFF AUTHORIZATION). The Union shall hold
     the Company free and harmless from any claims or damages from any party
     whatsoever for making deductions and shall indemnify the Company against
     any and all claims or damages which may originate from the dues check-off
     process.

2.2  NEW EMPLOYEES: The Company agrees to notify the Union of the name and
     address of new employees within thirty (30) days of their date of hire.

     direction of all working forces, including the right to hire, to suspend or

     vested exclusively in the Company.

3.2  DISCIPLINE: The Company retains the right to exercise discipline in the
     interest of good service and the proper conduct of its business, provided
     an employee who has been laid off, discharged, or disciplined shall be
     advised of the reason or reasons for such action and shall be allowed
     suitable representation, if so desired, at the time such reasons are
     provided. Furthermore, should the employee or the Union feel that the terms
     or conditions of this Agreement have been violated, either shall be
     entitled to grieve such action in accordance with the provisions set forth
     in Article 8 (GRIEVANCE PROCEDURE) of the Agreement.

                                 ARTICLE NO. 4
                                Union Activity

4.1  UNION BUSINESS: An employee who requests time off for Union activities, in
     addition to regular time off, shall be granted such request if such time
     off will not inconvenience the operations of the Company or increase its
     operating expenses; provided further, that such employee shall receive no
     compensation from the Company for such time off.

4.2  BULLETIN BOARDS: The Company agrees to permit the Union to use reasonable
     space for the purpose of posting officially signed Union bulletins upon the
     bulletin boards which are furnished by the Company.

4.3  UNION/STEWARD BUSINESS: The Union steward shall, upon request to the
     supervisor, be allowed reasonable time during regular working hours,
     without loss of pay, to attend to Union matters on the job, provided such
     time is not used for solicitation of membership or collection of dues, and
     does not interfere with regular work schedules.

4.4  CONTRACTING WORK: In case the Company should contract any type of work
     customarily performed by bargaining unit employees, the Company shall,
     before awarding such contract, advise the contractor that the work is to be
     done under not less than the terms and conditions pertaining to hours and
     wages set forth in this Agreement. Upon award of such contract, the Company
     shall notify the Union of such contractor and the nature of the work being
     performed.

                                 ARTICLE NO. 5
                              Status Of Employees

5.1  STATUS DESIGNATION: Employees shall be designated as part-time, \
     temporary, probationary, or regular.

     PART-TIME: A part-time employee is one who is hired for a job that is of
     indefinite duration and whose regular work schedule is not more than thirty
     (30) hours per week. The number of part-time employees shall not exceed the
     rate of one part-time employee to five regular employees (1:5) within the
     same classification. A part-time employee shall not displace any regular
     employee covered under the terms of this agreement and shall be limited to
     non-field type activities. After working 1,040 straight time hours, a part-
     time employee shall be eligible for group life and medical insurance
     (excluding dental and vision), covering the employee only. If a part-time
     employee is offered and accepts a regular position, an adjusted date of
     hire, crediting actual time worked, will be calculated. If the part-time
     employee has worked at least 1,040 straight time hours at the time the
     regular position is awarded, the employee shall be eligible for all
     applicable benefits on the effective date of the award.

                                    Page #6


     The ratio for part-time Meter Readers will be five (5) full-time employees
     for every one (1) part-time employee.

     The ratio for part-time Customer Service - Retail Customer Representatives
     will be five (5) full-time for every one (1) part-time employee.

     TEMPORARY: A temporary employee is one who is hired to fill a position for
     which there is temporary authorization. After working 1,040 straight time
     hours, a temporary employee shall be eligible for group life and medical
     insurance (excluding dental and vision), covering the employee only. If a
     temporary employee is offered and accepts a regular position, an adjusted
     date of hire, crediting actual time worked, will be calculated. If the
     temporary employee has worked at least 1,040 straight time hours, without
     cumulative absences of thirty (30) days or more at the time the regular
     position is awarded, the employee shall be eligible for all applicable
     benefits on the effective date of the award.

     If a temporary employee is offered and accepts a regular position that the
     employee has not previously occupied while at the Company, the employee
     must complete a probationary period to evaluate work performance. If,
     however, the employee has previously occupied the position being awarded,
     the employee shall receive credit toward the probationary period for actual
     time worked in that position.

     If an employee works at least 1,040 straight-time hours during a twelve
     (12) month period in the same temporary position, the position will become
     authorized and the employee will be offered regular status in that position
     at completion of that twelve month period.

     If an leased/agency employee works at least 1,040 straight-time hours
     during a twelve (12) month period in the same temporary position, the
     position will become authorized. The selection for the position will be
     made in accordance with Article 7, Seniority and Promotions.

     The Company will endeavor to provide the Union with a list of temporary and
     leased/agency employees and hours worked.

     PROBATIONARY: A probationary employee is one who is hired to fill an
     authorized position. After six (6) months of employment, a probationary
     employee shall be eligible for all benefits in accordance with this
     agreement.

     During the probationary period, the employee may be terminated at the
     discretion of the Company as long as the termination is not discriminatory
     and is not for the purpose of keeping jobs filled with probationary
     employees. Probationary employees who have not satisfactorily completed a
     formal departmental training and appraisal program may, at the discretion
     of supervision, have their probationary period extended by up to three (3)
     months. Supervisors shall not extend the probationary period if they do not
     have a formal training and appraisal program in place or have failed to use
     those programs. No later than two (2) weeks prior to the completion of the
     first six (6) months, the supervisor must notify the employee and the Union
     Business Manager in writing, if the probationary period will be extended.

                                    Page #7


     In computing the effective date of a change in status from a probationary
     to regular employee, interruptions in employment, caused by the following
     circumstances, shall not be credited:

          . Discharge

          . Resignation

          . Absence for more than an accumulative total of thirty
            (30) days due to:

               . Lay off
               . Sickness
               . Industrial disability
               . Other causes.

     If the employee's combined absences, during the probationary period, are
     for a period greater than the employee's combined actual work time, the
     employee shall be terminated. The transfer of a probationary employee from
     one job to another without interruption of work time shall not be
     considered a break in employment. At the end of the probationary period as
     defined above, the employee will become a regular employee and will rank in
     seniority from the original date of hire.

     REGULAR: A regular employee is one who has completed a probationary period
     and is in an authorized position. At that time, the employee is eligible
     for the benefits included in this agreement.

5.2  APPLICATION REFERRAL: The Company recognizes the Union as a valuable source
     for employment referrals, due to the mutual interest in the profitability
     of the Company. As such, when additional employees are needed to do work
     which comes under this agreement, the Company will indicate its
     requirements, relative to knowledge, skills, and abilities, and will give
     the Union an equal opportunity to refer applicants for employment. The
     Company retains the right to evaluate each candidate and make the final
     hiring decision.

5.3  TEMPORARY LAYOFF PROVISIONS: In recognition of the competitive nature of
     the utility business, innovative solutions are required when unforeseen
     challenges present themselves. Accordingly, there may be operational
     circumstances that would permit the temporary layoff of employees for
     short-term periods of time, out of line of seniority, on a voluntary basis.
     These provisions are detailed in Exhibit V (TEMPORARY LAYOFF PROVISIONS) of
     this agreement.

5.4  LAYOFF PROVISIONS:
     DEFINITION OF QUALIFIED: For purposes of defining "qualified", as used in
     -----------------------
     this Article, the definition shall be that an employee is qualified to
     perform any position, in either collective bargaining agreement, which the
     employee has previously occupied at the Company or any position that is an
     equal or lower classification which has been identified as being part of
     the employee's current trade/department progression. The progressions are
     detailed in a memorandum of understanding that is held by both the Company
     and the Union.

                                    Page #8


     NOTIFICATION: If it becomes necessary for the Company to layoff regular
     ------------
     employees due to lack of work, the Company shall give affected employees as
     much notice as possible; but in no event shall employees receive less than
     fourteen (14) calendar days notice of layoff. Where temporary, part-time
     and probationary employees are involved, no notice of layoff is required.

     SENIORITY: Layoff in all cases due to lack of work will be determined by
     ---------
     Company seniority within the classification affected by the layoff. If two
     (2) or more employees have the same Company seniority date, the following
     process will be used for breaking the tie: Alphabetically by Last Name ...
     if last names are the same, then First Name ... if last name and first name
     are the same, Middle Name; if last name, first name and middle name are the
     same, month, day of birth, and year will be used. Employees who are to be
     laid-off will be permitted to displace a less senior person in any
     classification for which they are qualified.

     RETURN TO BARGAINING UNIT: A member of the bargaining unit being
     -------------------------
     transferred to a non-represented position shall retain Company seniority
     for all purposes including layoff, if the employee is returned to the
     bargaining unit within one (1) year of the initial transfer.

     FOUR (4) YEAR QUALIFIER: Any MPAT employee of the company who accepts a
     -----------------------
     position in the bargaining unit will establish a new date of seniority for
     the purpose of future layoffs, except as defined above. This date will
     reflect the day in which these employees accept such a position and will be
     effective for four (4) years. If there is a reduction in classifications in
     the bargaining unit, these employees will use the above mentioned date as
     their seniority date for the purpose of this reduction or layoff. After
     four (4) years of service in the bargaining unit, any employee impacted by
     this language, will be credited with all Company seniority for the purposes
     of reduction in classification or layoff.

     RECALL: In the event of a recall, the Company shall provide notification to
     ------
     affected employees by certified mail to their address of record. Such
     employees must keep the Company informed of the address where they can be
     reached. Recalled employees must report to work no later than fourteen (14)
     calendar days from the date the certified letter was mailed. Employees who
     do not report to work within fourteen (14) days from the date the letter
     was mailed will be considered a voluntary quit. Employees will only be
     considered for recall to the classification from which they were laid-off,
     unless they make a written application within fourteen (14) calendar days
     from the date of notification of layoff, to human resources, for any other
     position for which they are qualified. Applications that do not meet this
     time frame will only be considered after all timely applications have been
     honored. Employees must submit a written notice to human resources to
     rescind their application for consideration for previously held positions
     prior to formal notification of return to work. Any employee who refuses a
     recall to any requested position will be considered a voluntary quit and
     will waive all recall rights to any other position. Employees who have
     displaced a less senior person in any classification shall be given an
     offer to return to their former jobs if the vacancy is in their former
     classification. Recall rights shall cease on any layoff in excess of twelve
     (12) months.

                                    Page #9


     EMPLOYMENT STATUS: Any regular employee who is laid-off due to lack of work
     -----------------
     has a right to replace any part-time or temporary employee within (5)
     working days after notification of layoff, provided the regular employee is
     qualified to perform the duties of the position filled by the temporary
     employee. If a regular employee is laid-off because of lack of work and is
     subsequently offered and accepts the first recall for employment within one
     (1) year after layoff, the employee shall resume the status of regular
     employee and shall be credited with Company seniority previously accrued.
     Employees who are recalled in a classification previously held, or for one
     in which they are qualified, will not be required to serve another
     probationary period and will be eligible for benefits immediately. However,
     employees who leave the service of the Company due to voluntary severance
     in accordance with this Article, or layoff and who are re-hired after one
     (1) year from the date of layoff or severance shall not be credited with
     Company seniority at the time of re-employment and shall be required to
     serve a new probationary period. Upon completion of five (5) years of
     subsequent service, an adjusted date of hire will be calculated crediting
     actual time worked with the Company. This date will be used for the
     purposes of Company seniority and all related benefits.

5.5  SEVERANCE: Full time employees hired on or before November 18, 1998, and
     who are laid off during the fourth (4th) year of the Agreement will receive
     the following benefits:

     ----------------------------------------------------------------
           Continuous Service with      Severance Benefit Period
                 Nevada Power
     ----------------------------------------------------------------
             6 months to 5 years                 6 months
     ----------------------------------------------------------------
             6 years to 10 years                 9 months
     ----------------------------------------------------------------
            11 years to 20 years                12 months
     ----------------------------------------------------------------
            21 years or more                    18 months
     ----------------------------------------------------------------

     The employee shall be entitled to receive the same medical and life
     insurance coverage that the employee had prior to the layoff for the same
     period as the Severance Benefit Period above.

     All other employees who are laid off will receive the following severance
     benefits:

     ELIGIBILITY:  Employees must have completed one (1) year of service to be
     -----------
     eligible for the minimum severance benefit.

     BENEFIT AMOUNT: Employees will be paid forty (40) hours at their straight
     --------------
     time rate for each year of service up to a maximum of three hundred twenty
     (320) hours. If eligible employees have completed nine (9) months of
     service since their most recent anniversary date, they will be considered
     to have completed an additional year of service for the purpose of
     calculating this benefit.

     If an employee exercises the right to displace a less-senior employee who
     occupies a lower paying classification and is laid-off from that
     classification within sixty (60) calendar days of this assignment, the
     severance benefit will be calculated at the rate of the employee's original
     classification.

                                   Page #10


           MEDICAL COVERAGE: Employees' current medical coverage, excluding
           ----------------
           dental and vision, will be continued at the applicable employee
           contribution for three (3) months following the effective date of
           layoff or severance.

           EMPLOYMENT STATUS: Employees who accept severance in lieu of bumping,
           -----------------
           waive any recall rights and will be considered a voluntary quit with
           the payment of the appropriate severance benefit. Employees presented
           this option must notify human resources of their decision within
           forty-eight (48) hours of the notification of layoff. Employees who
           do not have the option of bumping, and accept severance benefits,
           will retain recall rights for one (1) year from the date of layoff.

           Employees may agree in writing to waive their bumping rights as well
           as the appropriate severance benefit, thereby maintaining recall
           rights to the classification from which they were laid-off for a
           period of one (1) year. This decision must be made at the time of the
           initial notification of layoff and, once submitted, is irrevocable.

           Employees who have accepted severance and are subsequently recalled,
           will use that recall date for the purposes of calculating any
           severance benefit in the future.

           PAYMENT:  Any severance payment will be paid within five (5) calendar
           -------
           days of the date of layoff.

5.6        AFFILIATE COMPANY: It shall not be deemed a severance for the
           -----------------
           purposes of this Article if an employee is transferred to an
           affiliate of the Employer which is bound to this agreement provided
           that the Employee's new position is covered by the Collective
           Bargaining Agreement and is the same as the position held before the
           transfer.

                                           EXAMPLE
                                           -------
                 If Customer Service becomes a wholly owned affiliate of Nevada
                 Power Company severance under this article 5.5, represented
                 employees will not receive severance pay; this will not be
                 considered a break in service.

           --------------------
           circumstances such as weeks of vacation and vacation in association
           with holidays which will create special requests of the payroll
           department. Unless the situation is an emergency, all special checks
           will be limited to individuals who are absent for at least the
           Wednesday through Friday of a pay week. Exceptions to this practice

           schedule for re-payment will be agreed upon by the Company and the
           employee.

           TWO HOUR MINIMUM: Employees called out for overtime duty shall
           ----------------

           into their regular shift shall be paid the appropriate overtime
           premium for at least two (2) hours and straight time for the
           remainder of the shift. The two (2) hour call-out minimum applies but
           does not change the normal starting time.

            -------------------------------------------------------
                                    EXAMPLE
                                    -------

                    An employee who is called out one (1) hour
                    before the shift would be paid two (2) hours of
                    double time and seven hours of straight time.
            -------------------------------------------------------

6.9        REST TIME: Employees who are required to work overtime within the
           eight (8) hour period immediately preceding their scheduled starting
           time on a regular work day, shall be entitled to time off with
           straight time pay equal to time worked during this time frame. This
           is not applicable to a call out or scheduled overtime of three (3)
           hours or less immediately proceeding the employee's normal starting
           time.

           If an employee is entitled to rest time off, such time off would
           normally begin at the start of the regular shift. By mutual agreement
           between the supervisor and the employee, rest time may be taken
           during the last part of the regular shift. An employee shall not be
           required to work during his rest period provided adequate relief is
           available, however, should an employee be required to work during
           this period, he shall receive straight time for all time worked
           during his rest period in addition to his rest period pay.

6.10       CHANGE IN WORK SCHEDULE: Employees shall be provided at least
           twenty-four (24) hours notice of any change in work schedule. The
           notification period begins twenty-four (24) hours prior to the start
           of the changed work schedule. Employees who do not receive such
           notice shall be paid at one and one-half (1 1/2) times the employee's
           base rate for all hours worked outside their normal work schedule
           until such notice requirements have been satisfied. No notice is
           required to return employees to their regular work schedule.

           TRAINING EXCEPTIONS: The Company may for the purposes of training
           only, change schedules without incurring the premium penalties
           mention above. The Company will notify all employees as far in
           advance as possible, but not later than the end of their last
           scheduled work day in the week prior to such training. This
           notification will detail the nature, location and duration of the
           training. If such notification is not given, and an employee is
           called at home and informed of a change in schedule for training
           purposes, this employee will be paid time and one-half (1 1/2) for
           the first two (2) days of the training for all hours worked outside
           of their normal schedule.

                                   Page #15


           TRAVEL TIME FOR OUT OF TOWN TRAINING: Any employee who is required to
           travel out of town on a normal day off or after normal working hours
           for the purpose of Company training, will be paid actual driving time
           to and from the training site. When flying to such training,
           employees will be paid one (1) hour from their home to the airport,
           actual flying time to the destination, and one (1) hour from the
           airport to the hotel. All compensation for such travel time will be
           at a straight time rate and will not be considered time worked.

6.11       SHIFT DIFFERENTIAL: Fixed shift employees will be paid their shift
           differential for all hours worked on that day. For example, a second
           shift employee who works ten (10) hours on a particular day would be
           paid ten (10) hours of second shift differential.

           FIRST SHIFT:  No shift differential shall be paid for the first
           ------------
           shift.

           SECOND SHIFT: A differential shall be paid for the second shift

                  February 1, 2001  ....................  $1.50 per hour

           The appropriate overtime rate will be applied to the shift
           differential. Shift differentials shall be payable only for hours
           actually worked and shall not be payable for non-work time such as
           holidays, sick leave, vacation and rest time.

6.12       MEALS:
           MEAL TIMES: When working overtime before or after the regular day, or

           Meals will be provided as close to these times as circumstances of
           the work will permit. Employees may elect to complete their
           assignment and take their meal period upon completion of their task.
           This meal period would be unpaid time unless directed by supervision
           to work through the meal period and such work continues more than one
           (1) hour from the stated meal time. This paid meal period will be
           limited to one-half (1/2) hour at the appropriate rate of pay.

                                   Page #16


           For purposes of this Article, no meal allowances will be provided for
           any scheduled overtime work on an employee's usual days off when the

           shift.

           MEAL RATES: When employees are released on or after a normal meal
           ----------
           period, or periods as outlined above, and do not elect to eat a
           Company provided meal, they shall be given a meal allowance of $9.00.
           These allowances will be paid through the payroll system in the
           employee's next paycheck. The meal allowance shall be increased to:

           -----------
           allowance, the cost of any meal shall not exceed two (2) times the

           amount, the employee will be notified of the amount of the difference
           and the employee must reimburse the amount within thirty (30)
           calendar days after receipt of such notification. These limitations

           place an undue hardship on the employee.

6.13       VEHICLE USAGE: No employee shall be required to operate a personal
           vehicle in the course of employment as a condition of employment.
           Employees shall be required to obtain a Nevada driver's license
           whenever operation of a Company provided vehicle is a requirement of
           the job.

           Employee's who are authorized to use personal vehicles in the course
           of their employment shall be compensated for use of the vehicle at a

- --------------------------------------------------------------------------------
Example 1: If employees are assigned to work at an office other than their
     normal base reporting point, after they have already reported for work at
     their normal base reporting point, and no Company vehicle is available,
     they shall be compensated for use of their vehicles for the actual miles
     traveled from office-to-office as designated on the chart attached at the
     rate equal to the Internal Revenue Service (IRS) maximum mileage expense.
     If they return home directly from that office, they shall not be
     compensated for the miles traveled from the office to their home.

Example 2: If employees report for work at an office other than their normal
     base reporting point directly from home, they shall not be compensated for
     the miles traveled from their home to the office nor from the office to
     their home. Only those miles traveled from are office-to-office
     compensable.

           Any employee who is authorized the use of a private vehicle during
           the course of his or her employment shall be provided liability
           protection under the terms of the public liability and property
           damage insurance policy maintained by the Company as if the employee
           were operating a Company-owned vehicle except that if the laws of the
           State of Nevada establish that the personal insurance policy of the
           employee shall be the primary insurance, then such consideration
           shall be first applied. In the event of an accident involving an
           uninsured motorist where damages to the employee's private vehicle
           are not recoverable from the responsible party, then costs of
           repairing such damage shall be reimbursed by the Company.

6.14       REQUIRED NOTICE: The Company will provide two (2) days' notice when
           an employee is assigned to work in an office other than the
           employee's base reporting point. If the Company does not provide two
           (2) days notice, the employee shall be paid one (1) hour at time and
           one-half (1 1/2) for each day until the two (2) day notice period has
           been satisfied.

                           Seniority and Promotions

7.1        SENIORITY: There shall be one (1) type of seniority, namely, Company
           seniority. Company seniority shall be considered in such matters as
           retirement, lay off, and whenever provisions of this agreement refer
           to seniority. In cases where two or more employees have the same
           Company seniority, the employee with the higher total score on the
           most recent performance appraisal shall have the greater seniority.

7.2        SENIORITY POSTINGS: The Company shall post a Company seniority list
           on bulletin boards every six (6) months and shall mail a copy of this
           list to the Union when the list is posted and after any corrections
           are made. Any seniority corrections should be made in writing to
           human resources.

7.3        STAFFING VACANCIES:
           POSTING REQUIREMENT: When there are no qualified employees who have
           -------------------
           requested an intra-departmental work location change into job
           vacancies which are expected to last for more than ninety (90) days,
           the Company shall post such job vacancies or new jobs on bulletin
           boards for a period of seven (7) calendar days. It shall be the duty
           of the Company to set forth in said bulletins the nature of the job,
           its location and duties, reasonable qualifications required and the
           rate of pay, unless such information is listed in the collective
           bargaining agreement. At the same time, the Company will furnish the
           Union a copy of this bulletin. Employees may file their applications
           in the Human Resources department by Company mail or by U.S. Mail.
           However, the Company may not consider any application received after
           the job bid closing date. All job vacancies must be awarded within
           twenty-one (21) calendar days of the job bid closing date. If the
           award is not made within twenty-one (21) calendar days, and is not
           delayed due to vacations or bid hearings, the successful employee
           will be paid the new rate for the period from the twenty-one (21)
           days to the date of the award. This does not apply to the time frame
           of up to three (3) weeks after the award for the purpose of
           transitioning responsibilities.

           JOB POSTING SYSTEM: The Company shall publish job posting and
           ------------------
           awarding procedures which, at a minimum, comply with the provisions
           of this agreement. These procedures will constitute the Company's job
           posting system. Any bargaining unit employee covered by either the
           clerical or plant collective bargaining agreements may apply and
           compete equally for any position within the Company. Employees are
           disqualified from bidding if their most recent performance appraisal
           total score is less than 2.5 or if they have a letter of discipline
           which is less than one (1) year old in their Human Resources
           personnel file.

                                   Page #19


           SELECTION CRITERIA: Exclusive of the provisions of Articles 7.9
           ------------------
           (INTRA-DEPARTMENTAL WORK LOCATION CHANGE), in filling vacancies the
           following factors shall be considered:

                . Trade Knowledge

                . Training

                . Past Performance with the Company

                . Ability, skill, adaptability, efficiency

                . In addition, the Company retains the right to administer
                  equally fair tests, demonstrations, or physical assessments
                  when such tests will assist materially in determining the
                  qualifications of employees.

           When, in the discretion of the Company, all factors are substantially
           equal, Company seniority shall govern.

           HEARING PROCEDURES: In lieu of any grievance procedure concerning
           ------------------
           Article 7.3 (STAFFING VACANCIES), the Company shall offer the three
           (3) most senior bidders (if applicable) and the employee with the
           second highest matrix score (if applicable) who are more senior than
           the successful bidder a hearing before the bid committee with the
           steward for the department, the senior person or persons and one (1)
           other Union member. If the number of senior bidders exceeds the
           parameters mentioned above, a group meeting will be conducted with
           the remaining senior bidders to explain the decision and answer any
           relevant questions. The Company shall not assume any penalty for bid
           hearings that are delayed.

           NO QUALIFIED BIDDERS: If no applications are received from any
           --------------------
           qualified bargaining unit employees within the posting period, the
           Company may then fill the job from outside the bargaining units.

7.4        TEMPORARY APPOINTMENTS: Wherever a vacancy occurs in any job
           classification, the Company may, at its discretion, temporarily fill
           such vacancy. If practical, any such temporary appointment shall be
           given to an employee who would be eligible under the provisions of
           this agreement.

7.5        JOB DESCRIPTIONS: When advances in technology or other changes that
           materially affect job duties and responsibilities, IBEW and NPC will
           agree to revise job descriptions as needed.

7.6        MOVING EXPENSES: Should the Company assign an employee, who has not
           volunteered for reassignment, to an established Company headquarters
           located more than thirty (30) driving miles by the most reasonable
           route from his regularly established Company headquarters, and such
           assignment is not temporary in nature, the Company will pay the
           employee $1200 for moving expenses, for the purpose of establishing a
           new primary residence, within a two (2) year period immediately
           following such assignment. In addition, the Company shall pay the
           actual costs to relocate a mobile home which is the employee's
           primary residence.

                                   Page #20


7.7        SUB-DEPARTMENTS: When employees are awarded bids in the
           sub-department in which they are working, in accordance with Article
           7.3 (STAFFING VACANCIES) of this agreement, their rate of pay for the
           awarded job shall be the rate established for the classification as
           listed in the appropriate agreement. If the awarded job has more than
           one rate, such rates being based on time spent in classification, the
           employees shall be assigned the lowest rate in the classification
           which will provide an increase to the employees. Employees thus
           assigned a rate step above the starting rate will not advance to a
           higher step until they have served the time indicated by the assigned
           step. Should no rate in the classification provide an increase, the
           employee shall be assigned the "there-after" rate of the new
           classification.

                                    EXAMPLE
                                    -------

               A Fleet Utility Technician being paid $16.00 per hour,
             enters an apprentice program which has four (4) annual
             step rates of $14.50, $15.50, $16.50, and $17.50. The
             Fleet Utility Technician will receive the rate of $16.50
             and remain at that step for three (3) years before
             advancing to the next step.

           For purposes of this Article, "sub-departments" are the Customer
           Service/Energy Services, Major Customer Services (LGS Billing), Field
           Service, Meter Shop, Districts, Material/Warehousing, Reprographic
           Services and Mail Room/Receiving Departments.

7.8        TIME IN CLASSIFICATION PAY: When employees are awarded bids in a
           different sub-department from which they are working, their rate of
           pay for the awarded job shall be the rate established for the
           classification as listed in the appropriate agreement. If an employee
           has previously occupied the position, the employee shall be given
           credit for time spent in that position for the purposes of
           establishing the new rate. Where the awarded job has more than one
           rate, such rates being based on time spent in classification,
           employees shall be assigned the starting rate for the new
           classification unless such rate will result in a lesser rate than
           their former classification. If assigning the starting rate to
           employees awarded the job would result in a lesser rate than their
           last rate, employees shall be granted one year of credit or the
           amount of their Company seniority, which ever is less, as time spent
           in the new classification for the purpose of establishing their new
           rate of pay.

7.9        TRIAL PERIOD: Employees promoted or transferred in accordance with
           this Article shall be employed on the job to which they were promoted
           or transferred for a reasonable trial period not to exceed six (6)
           months. If, following the trial period, they are still unable to
           perform the job to which they are promoted or transferred, they shall
           be returned to the former job classification they held or to their
           former or another job classification of similar requirements and the
           previous rate of pay, as determined by the Company. Employees who are
           returned to another classification in accordance with this Article
           shall not be permitted to bid on another position for six (6) months
           from the time they are returned.

                                   Page #21


7.10       INTRA-DEPARTMENTAL WORK LOCATION CHANGE: Employees desiring to change
           work locations within the same sub-department and classification
           shall submit a work location change form to the appropriate
           department head. Through labor/management meetings, departments shall
           develop procedures for work location changes.

                                 ARTICLE NO. 8
                              Grievance Procedure

8.1        DEFINITION: A grievance shall be defined as a dispute regarding the
           interpretation and application of the provisions of this Agreement
           filed by the Union or by an employee covered by this Agreement
           alleging a violation of the terms and provisions of this Agreement.
           However, disputes specifically excluded in other Articles of this
           Agreement from the Grievance Procedure shall not be construed as
           within the definition set forth above.

8.2        TIME LIMITATIONS: The Company and the Union recognize the mutual
           gains process as an effective tool in resolving differences in the
           work place. Once timely notification of a grievance has been given,
           the Union and Company may mutually agree to extend the time
           limitations to ensure that interests are clearly defined, witnesses
           and all persons involved receive proper notification and are able to
           attend, evidence is accurate, and remedies are thoroughly explored
           before moving to the next step. However, it is in the interest of
           both the Company and the Union to expedite the process and encourage
           the timely resolution of the issue in order to satisfy established
           time constraints.

           The Union and Company, by mutual agreement, may elect to bypass
           certain steps, due to the nature of the grievance.

           Except by mutual agreement to extend the time limitations, an
           arbitrator shall not have the authority to excuse a failure by the
           Union, the Company or the aggrieved employee to comply with the time
           limitations set forth, regardless of the reason given for such
           failure.

8.3        GRIEVANCE PROCESS:
           NOTIFICATION: When a dispute arises relative to the administration of
           ------------
           the provisions of this agreement, the employee and/or Union steward
           must complete a mutual gains issue form and submit it to the
           appropriate supervisor for signature no later than thirty (30)
           calendar days after the grievance first arises. The time period shall
           start from the first day the Company can show that the Union or an
           employee affected by the Company's action knew or should have known
           of the situation.

                                   Page #22


           At each step in the process, the Union shall officially sign off on
           the mutual gains issue and grievance forms, verifying that their
           interests have been satisfied or to pursue resolution at the next
           step.

           STEP ONE (MUTUAL GAINS MEETING - SUPERVISOR): The supervisor shall
           -------------------------------------------
           schedule a meeting with the grievant and steward within seven (7)
           calendar days of receipt of the mutual gains issue form. The grievant
           and the supervisor will define interests and work on resolving the
           issue in a manner satisfying those interests. If the issue is not
           resolved at step one (1), the mutual gains issue form may be referred
           by the Union to the next level of supervision within three (3)
           calendar days of the step one (1) meeting.

           STEP TWO (MUTUAL GAINS MEETING - LEVEL II SUPERVISION): The next
           -----------------------------------------------------
           level of supervision shall schedule a meeting with the grievant,
           steward, and supervisor within seven (7) calendar days of receipt of
           the mutual gains issue form. The grievant and supervision will define
           interests further and work on resolving the issue at this level. If
           they are unable to satisfy interests, the Union may request a formal
           hearing within three (3) calendar days of the step two (2) meeting.

           STEP THREE (MUTUAL GAINS HEARING): The level II supervisor shall
           --------------------------------
           schedule a hearing with the grievant, steward, supervisor, and
           official Union and Employee Relation representatives within seven (7)
           calendar days of receipt of the mutual gains issue form. Witnesses
           will be designated to testify and related evidence shall be
           submitted. Those in attendance shall discuss possible remedies, which
           will be implemented upon final approval by the official Union and
           Employee Relation representatives. This joint decision shall be final
           and binding on all parties. If, at the conclusion of step three (3),
           the two (2) parties are unable to resolve the issue, the grievance
           shall be reduced to writing on the grievance report form, citing the
           Article and/or section of this agreement which has been allegedly
           violated, and the Company shall sign, date, and acknowledge receipt
           of such grievance.

           STEP FOUR (UNION/COMPANY MEETING): The Union Business Manager and
           --------------------------------
           Director of Employee Relations & Diversity shall schedule a meeting
           within ten (10) calendar days of receipt of the grievance report
           form. The department supervisor and/or manager, and the grievant
           and/or Union steward may be present at the request of either party.
           The Company and Union shall review the information provided, conduct
           further investigation if necessary, and shall render a joint decision
           which shall be final and binding on all parties. If the grievance is
           not settled at step four (4), the Company will communicate its
           position in writing within five (5) calendar days of the step four
           (4) meeting. This written notification will be sent via certified
           mail.

           STEP FIVE (ARBITRATION): Within fifteen (15) calendar days of receipt
           ----------------------
           of management's position, the Union may request arbitration by
           delivering a written notice to the Employee Relations & Diversity
           office of its intent to arbitrate the dispute. If the Union does not
           respond within fifteen (15) calendar days, the issues involved in the
           grievance will be considered resolved and the matter closed.


           Within five (5) working days after receipt of the notice of intent to
           arbitrate, the parties will request the Federal Mediation and
           Conciliation Service to furnish a list of five (5) arbitrators from
           the southwest region of the United States from which the arbitrator
           shall be selected. Such selection shall be accomplished by the Union
           and the Company striking one (1) name from the list in turn until
           only one (1) name remains.

           In recognition of the magnitude of such decisions, arbitration
           relative to termination grievances shall be expedited whenever
           possible. Unless mutually agreed to extend the time limitations in
           writing, these grievances should be arbitrated within six (6) months
           of the termination date.

           The arbitrator's decision shall be submitted in writing and shall be
           final and binding on all parties to this Agreement. Nothing contained
           in this contract or any part thereof shall affect or apply to the
           Union in action it may take against the Company for failure to comply
           with any legally enforceable decision reached through arbitration.

           The cost of the arbitrator and the cost of necessary expenses
           required to pay for facilities and recording of the hearing of cases,
           shall be borne equally by the Company and the Union.

           The arbitrator shall not have the authority to modify, amend, alter,
           add to, or subtract from any provision of this Agreement.

           leaders in providing and promoting a safe workplace. The Company
           shall make reasonable provisions for the safety of employees in the
           performance of their work. The Union shall cooperate in promoting the

           Committee. The selection of the Company's Safety Committee members
           shall be made jointly by the Chairman of the committee and the
           Business Manager of the Union. The Chairman of this committee shall
           be selected by the Company. Each year thirty three and one third
           percent (33-1/3%) of the committee members shall be replaced in

           inspection of the Company facilities. If required, these inspections
           may occur more often at particular facilities. The Committee Chairman
           may request additional employees who work at the site to assist in
           the inspection. The Company will allow the appointees reasonable
           time, as determined by the Chairman, to perform this inspection. They
           will prepare a written report including recommendations for
           corrective actions and forward it to the Committee Chairman and
           Company President.

9.7        SAFETY INVESTIGATIONS: When a lost time disabling injury occurs as a
           result of a suspected careless act or unsafe working condition, a
           safety investigating committee shall be chaired by Safety Services to
           review the facts and reconcile safety deficiencies and recommend
           corrective action. A safety committee member designated by the Union
           and assigned to the work area in which the injury occurred, shall
           serve on the investigating committee.

           similar cause, are unable to work in the field that day, shall
           receive pay for the full day. However, they may be held pending
           emergency calls and may be given first-aid, safety or other
           instruction, or they may be required to perform miscellaneous work in
           the yard, warehouse, or other sheltered locations. Through
           labor/management meetings, and in conjunction with safety services,
           each department shall establish policies which clarify safe work
           procedures during inclement weather.

                                   Holidays

11.1       ELIGIBLE EMPLOYEES: Regular employees and probationary employees who
           are eligible for benefits, shall be entitled to holidays off with
           pay. Employees on leaves of absence or disability leave are not
           entitled to holiday pay, except if the employee begins leave or
           returns from leave during the week of a holiday.

11.2       WORKED HOLIDAYS: Shift employees may be permitted to take holidays
           off which fall on their scheduled work days. Employees scheduled to
           work on a holiday shall be paid at the rate of time and one-half (1
           1/2) for time worked during regular working hours in addition to
           holiday pay. Employees who are called out to work on a holiday shall
           be paid at the rate of double time for time worked in addition to
           holiday pay. Time worked in excess of the regular work day will be
           paid at the appropriate overtime premium. Except for shift employees,
           holidays listed below shall not be considered scheduled work days.

11.3       COMPANY HOLIDAYS: When a holiday falls on a Saturday, the preceding
           Friday shall be observed, and when a holiday falls on a Sunday the
           following Monday shall be observed. Whenever an employee's regular
           days off are other than Saturday and Sunday, the first day off within
           the work week shall be considered as Saturday and the second day off
           within the work week shall be considered as Sunday for the purpose of
           this Article. A rotating shift employee working on a schedule which
           provides four (4) consecutive days off shall observe the day prior to
           the four (4) days if the holiday falls on the first of the four (4)
           days, and shall observe the day following the four (4) days if the
           holiday falls on any of the other three (3) days for the purpose of
           this Article.

11.4       FLOATING BIRTHDAY/HOLIDAY: An employee may observe the floating
           holiday on any work day of the year with mutual agreement by the
           employee and supervisor. Or, with seven (7) calendar days notice, an
           employee shall observe the floating holiday on any work day which
           falls in the same calendar week as the employee's birthday. For the
           purpose of this Article, the calendar week begins Sunday and ends
           Saturday. Should an employee be called in or required to work on a
           previously approved "holiday," the employee shall be paid the
           applicable overtime rate, except if both the employee and supervisor
           mutually agree to change the observance of the holiday.

           Employees who request to use their floating holiday for the purpose
           of recognizing a religious observance, will be accommodated whenever
           possible. Any difficulties in this regard should be forwarded to the
           Employee Relations area of Human Resources.

                                   Page #28


11.5       BANKED HOLIDAYS: If eligible employees are required to work on any
           day observed as a holiday and are authorized to work for the straight
           time hourly rate of pay, then an equal number of hours will be
           allocated to their banked holiday account. With written consent of
           the Company, employees may carry over up to sixteen (16) hours of
           banked holidays to the next year.

11.6       PART-TIME, TEMPORARY AND BENEFIT INELIGIBLE EMPLOYEES: Part-time,
           temporary, and probationary employees who are not eligible for
           benefits will not receive pay for holidays not worked but shall be
           paid the appropriate overtime premium for all time worked on
           holidays.

11.7       SICK LEAVE IN CONJUNCTION WITH A HOLIDAY: An employee who does not
           report for work either the day before and/or the day after a paid
           holiday, and who has not been excused by his or her supervisor for
           either the day before and/or the day after a paid holiday shall
           receive no pay for the holiday. The Company may require satisfactory
           evidence of an employee's illness or injury before holiday pay will
           be granted. If the Company requires medical evidence, the Company
           must inform the employee of the requirement to provide evidence no
           later than two (2) hours after the employee's regular starting time
           on the day of the absence. If required and the employee does not
           comply with this request, the employee will not be paid for the
           holiday or the day of absence, and may be subject to disciplinary
           action.

11.8       ALTERNATIVE SCHEDULES: As a result of the implementation of
           alternative work schedules, any issues associated with the provisions
           of Article 11 will be resolved by memorandum of understanding between
           the Company and Union.

           the calendar year in which it is earned, subject to the following
           considerations.

                 minimum of interference with service to the Company's
                 customers, and;

               . The selection of all vacation periods based on the employee's

12.2       FIRST TWO (2) CALENDAR YEARS OF EMPLOYMENT: Probationary and regular
           employees shall earn vacation during the first two (2) calendar years

           31 years and above.......................................240 hours

12.4       VACATION ADJUSTMENTS: An employee's vacation accrual shall be
           adjusted for all periods of leave of absence including leaves for
           illness or injury as defined elsewhere in this agreement by reducing
           the number of vacation hours accrued in direct proportion to the
           number of hours of leave within the employee's anniversary year. Such
           reductions shall be applied to any accrued and unused vacation
           available in the calendar year the adjustment is made, or when such
           adjustment exceeds the employee's available vacation, the excess
           shall be applied against the employee's next vacation accrual or the
           employee's final paycheck, whichever occurs first. It is understood
           that no adjustment to vacation accrual will be made for sick leave or
           during the first sixty (60) calendar days of any disability leave.

12.5       VACATION BONUS: In addition to the vacation accrued in accordance
           with the above schedule, any employee who completes ten (10) years
           continuous service and each five (5) years of continuous service
           thereafter, shall be granted a vacation bonus of forty (40) hours in
           the year such term of employment is attained. The vacation bonus will
           accrue, and may be taken subject to the provisions of this Article.

                                   Page #30


12.6       UNUSED VACATION: All unused or carried over vacation time accumulated
           in the year of termination after an employee's first anniversary
           date, up to and including the employee's last day worked, shall be
           paid at termination of employment, at the employee's current base
           rate. This does not apply to the vacation bonus when the employee has
           not completed the minimum service specified.

           It is understood that employees may not carry vacation time over to
           the following year without the written consent of the Company.

           A regular employee who has been laid off for lack of work and is
           recalled within one (1) year, who has in excess of one (1) year
           Company seniority, shall accrue vacation in accordance with Article
           12.4 (VACATION ADJUSTMENTS).

12.7       DEPARTMENTAL POLICIES: Each department will develop standards and
           procedures for scheduling vacations which, at a minimum comply with
           Article 12.1 (CONSIDERATIONS).

12.8       HOLIDAY WHILE ON VACATION: If a holiday occurs on a work day during
           an employee's vacation, it shall not be counted as hours of vacation.
           The employee shall receive straight time pay for the holiday.

12.9       HOSPITALIZED WHILE ON VACATION: Employees on vacation who become
           hospitalized for at least one day, shall not be required to use
           vacation time during the period of incapacitation. Employees who are
           capable of completing any light duty must choose to remain on
           vacation or report for light duty.

12.10      CALL-OUT WHILE ON VACATION: An employee shall not be expected to work
           on his regularly scheduled days off immediately preceding or
           following pre-scheduled vacation. However, if an employee is called
           out and accepts such an assignment on the regularly scheduled days
           off immediately preceding or following pre-scheduled vacation, the
           employee shall receive the appropriate overtime rate for this work.
           An employee called out during scheduled vacation will be paid double
           time for all hours worked and the employee may reschedule the unused
           portion of his vacation hours in accordance with Article 12.1
           (CONSIDERATIONS) above, if the call-out was for work during the
           employee's normal work hours. Additionally, if the call-out creates
           rest time, the employee may reschedule vacation equal to the rest
           time earned from this assignment.

                                  Sick Leave

13.1       ELIGIBILITY: A regular employee and a temporary employee with more
           than 1040 hours shall be entitled to accumulate sick leave with pay
           at the rate of eight (8) hours of sick leave for each month worked.

13.2       NOTIFICATION AND VALIDATION: The Company may require satisfactory
           evidence of an employee's illness or disability before sick leave
           will be granted. If an employee abuses the sick leave provisions of
           this Agreement by misrepresentation or falsification, the employee
           shall restore to the Company all sick leave payments received as a
           result of such abuse. An employee must notify their supervisor or a
           member of management, or see that their supervisor is notified, as
           soon as it is apparent that the employee will be unable to report for
           work. The employee must provide this notification before the
           beginning of the normal work day. The employee should notify the
           supervisor as far in advance as possible of the expected date of
           return. Lack of notification without a reasonable explanation will
           result in denial of sick pay benefits.

13.3       EXCLUSIONS AND EXCEPTIONS. Employees shall not be entitled to sick
           leave while on vacations (except as provided in Article 12.9
           [HOSPITALIZED WHILE ON VACATION]), while temporarily laid off by the
           Company, during the period of notice of severance of employment, upon
           severance of employment, or while receiving disability payments or
           industrial compensation. Exhibit IV (SICK LEAVE AGREEMENT) of this
           Agreement establishes other rules and interpretations for the
           administration of these sick leave provisions.

13.4       SICK LEAVE BONUS: Employees who are eligible for sick leave in
           accordance with Article 13.1 (ELIGIBILITY), who use no more than two
           hundred twenty (220) hours of sick leave each five (5) years, shall
           be granted a bonus of five (5) days vacation in addition to that
           granted under the provisions of Article 12.3 (ACCRUED VACATION), each
           five (5) years based on the following considerations:

                . On January 1, 1987, and January 1, of each fifth year
                  thereafter, the sick leave records of those employees with
                  hire dates prior to August 1, 1981, will be audited. Those
                  employees who have used no more than two hundred twenty (220)
                  hours of sick leave during the five (5) year period
                  immediately preceding the audit will be granted five (5) days
                  vacation to be taken within the twelve (12) month period
                  immediately following the audit date and in accordance with

           opinion of the Company's doctor after consultation with the
           employees' doctor, regular employees with at least one (1) year of
           Company service cannot perform their regular work because of partial
           disability, but can perform other work, the following plan shall be
           applicable:

           Each case shall be considered on its merits by a committee consisting
           of the Business Manager of the Union and the Director of Employee
           Relations, or their designated representative, and two (2) additional
           members, one (1) of whom shall be designated by the Union and the
           other by the Company. The committee shall have the authority to waive
           the seniority and bidding provisions of this Agreement in order to
           place the disabled employee, and it shall determine the seniority
           rights of such employee. This committee may call on anyone who may be
           able to furnish pertinent information.

           In no event will this Article apply if the employee's disability
           occurs while self-employed or working for others, for remuneration
           (except on Union business), or is involved in misconduct or an
           extreme violation of Company safety rules.

           The panel shall complete an evaluation of the type of work the
           employee is able to perform or may be able to perform in the future.
           Evaluation of the employee's capabilities may include but shall not
           be limited to a physical examination and doctors reports, the
           employee's physical and mental ability, willingness to work, and
           trainability.

                                   Page #39


           Depending upon the evaluation of the employee and where necessary and
           practical, the Company shall provide job related education and
           training. The panel shall also conduct periodic review of these cases
           to determine if an employee's condition has changed; if the
           employee's condition has changed, the panel will reevaluate the
           employee's job assignment.

           The panel will determine the job classification which is appropriate
           for the work the employee is able to perform, as well as the proper
           pay rate, taking into account the new classification pay rate or the
           rate indicated on the following schedule, whichever is greater.

               Years Of Company Service     A Pay Rate That Is Not Less Than
               ------------------------     --------------------------------
                1 to 4 years inclusive          70% base rate when injured
               5 to 14 years inclusive          80% base rate when injured
              15 to 24 years inclusive          85% base rate when injured
                     25 years and over          90% base rate when injured

           As long as such employee is paid more than the maximum rate for the
           job classification in which the employee is placed, the employee
           shall receive only fifty (50) percent of any base wage increase or
           lump sum payment in lieu of a base wage increase. Such fifty (50)
           percent shall be calculated on the employee's personal rate at the
           time of the increase.

           The placing of a disabled employee in a different job shall not
           constitute an increase in the Company's normal work force. However,
           the Company may temporarily increase the number of authorized
           positions to accommodate an individual when a future vacancy is
           clearly defined and recognizable.

           If the committee is unable to place an individual in accordance with
           these provisions they would be eligible for vocational rehabilitation
           training, and benefits through the Employers Insurance Company of
           Nevada. Upon this determination, the individual's employment with the
           Company will be terminated, and any accrued benefits will be paid at
           the time of termination.

           The parties agree that the provisions of this Article may be
           suspended with sixty (60) days written notice, documenting the
           reasons for this request and the interests which would need to be
           addressed for the continuance of this program.

14.4       SHORT TERM DISABILITY BENEFIT: A regular employee, or a temporary
           employee who has worked more than one thousand forty (1040) straight
           time hours who shall suffer any disabling illness or injury while not
           in work status, shall be entitled to disability payments in such
           amounts and under such conditions as described herein:

                                   Page #40


          . An eligible employee shall be entitled to receive payments not to
            exceed the percent of the employee's weekly straight time earnings,
            such earnings to be computed on the employee's regular rate for a
            forty (40) hour, seven (7) day period, for a maximum period of
            benefits at the percent of earnings as defined in the following
            schedule of benefits.

                                         MAXIMUM             PERCENT OF
                  LENGTH                 PERIOD OF              BASE
                OF SERVICE               BENEFITS             EARNINGS
                ----------               --------             --------

                 6 months*               13 weeks                55
                   5 years               26 weeks                60
                  10 years               52 weeks                65
                  15 years               60 weeks                70
                  20 years               65 weeks                75

          * Employees in this category may be granted up to thirteen (13)
            additional weeks of leave without pay for continued disability.

          . No disability payments for an illness shall be made until at least a
            three (3) days waiting period has been observed, however, an
            employee must use accrued sick leave to satisfy the waiting period
            or to extend the waiting period to the maximum of the amount of
            accrued sick leave.

          . Any female employee who becomes pregnant and is unable to work shall
            be entitled to disability benefits under this Article, as described
            above, subject to the following conditions. She must present a
            document from her attending physician saying that she is under the
            doctor's care because of the pregnancy and is unable to work. The
            period of the disability shall begin at least three (3) days after
            the attending physician declares the employee disabled and shall end
            when the employee is no longer disabled as determined by the
            attending physician. Pregnant employees must use all accumulated
            sick leave before disability payments will start. A female employee
            will not be eligible for pregnancy related disability benefits
            except for her own disability. An employee who is on maternity leave
            and recovering from disability may request to have her leave
            extended for up to three (3) months after termination of pregnancy
            for child care or other reasons.

          . Any employee who performs activities for which compensation is
            received or which exceed the scope of the prescribed physical
            limitation pertaining to such disability while receiving disability
            compensation described in this section, shall forfeit their
            entitlement to all disability benefits and their employment shall be
            terminated.

                                   Page #41


          . Any employee who returns to work in a light-duty status from short-
            term disability will not create a new benefit eligibility until they
            have had a full-duty release and worked for thirty (30) calendar
            days from the time of that release. If an employee returns to short-
            term disability without satisfying this requirement, their short-
            term disability benefit will reflect their prior usage and continue
            until expiration of such benefits.

          . Any employee who is unable to perform the duties of their position
            as a result of a non-job-incurred injury, would be considered for
            any vacancy for which they are qualified. If awarded a position in
            accordance with Article 7 (SENIORITY AND PROMOTIONS), the employee
            would receive the appropriate rate of pay for that position.

          . Any employee that exhausts their short-term disability benefit and
            is unable to return to work at that time, may request one unpaid
            leave of absence for up to ninety (90) days to allow time for
            further recuperation or possible vacancies for which they are
            qualified. Such employees will be allowed to continue their medical
            coverage at the appropriate COBRA rate for this period of time. If
            this individual is unable to return to work at the expiration of
            this unpaid leave, their employment with the Company will be
            terminated and all accrued benefits will be paid at the time of
            termination.

14.5  RETIREMENT BENEFIT: The Nevada Power Company Retirement Plan, a defined
      benefit pension plan bearing No. 003, including the amendments dated March
      5, 1980, shall be incorporated by reference into this Agreement. The
      Company has, since January 1, 1976, been paying the entire cost of this
      retirement plan. All participants in the pension plan which was in effect
      before January 1, 1976, have and are guaranteed all accrued benefits under
      that pension plan as computed on December 31, 1975.

      Effective February 1, 1990, the pension plan was amended to delete the
      provision that the selection of a surviving spouse benefit will revert to
      a single life annuity if the spouse predeceases the retired employee.

      Effective February 1, 1994, the pension plan was improved to provide for
      early retirement benefit reductions of 5% per year from age sixty-two
      (62).

      Effective January 1, 1989, the pension plan was changed from a social
      security offset plan to a step rate plan. Effective February 1, 1998, the
      formula for calculating benefits will be 1.35% of final five-year average
      earnings up to Social Security Covered Compensation, plus 1.8% of final
      five-year average earnings exceeding covered compensation, times service
      up to 35 years, plus 1.35% of final five-year average earnings, times
      service over 35 years. For this purpose, final five-year average earnings
      is the average of the highest sixty (60) consecutive months of earnings.

                                   Page #42


      Effective February 1, 2001, the formula for calculating benefits will be
      1.365% of final five-year average earnings up to Social Security Covered
      Compensation, plus 1.8% of final five-year average earnings exceeding
      covered compensation, times service up to 35 years, plus 1.365% of final
      five-year average earnings, times service over 35 years. For this purpose,
      final five-year average earnings is the average of the highest sixty (60)
      consecutive months of earnings.

      Effective February 1, 1987, entry into the pension plan shall be on the
      first day of the month coincident with, or following completion of one
      year of service and attainment of age twenty-one. Participants in the plan
      prior to February 1, 1987, shall enter the plan on the first day of the
      month coincident with, or following completion of one (1) year of
      eligibility service and attainment of age twenty-one, unless those
      participants had declined enrollment under the eligibility rules in effect
      when they had first become eligible.

      Effective February 1, 1987, vesting service shall be measured from the
      employee's date of hire or age eighteen, whichever is later. The Company
      shall make such modifications in the plan as may be required by 1) the
      Internal Revenue Service in order to qualify said benefits under the
      applicable provisions of the Internal Revenue Code and/or related rules
      and regulations; or 2) any other governmental agency having jurisdiction.
      Other modifications may be made as needed but in no event shall any
      benefits be reduced during the term of this Agreement.

      Effective February 2, 1998, all sick leave accrued at time of retirement
      will be added to the years of service for fully vested participants only.

         ----------------------------------------------------------------
                                    Example
                                    -------

          If an employee retires June 5, 1998 and has 400 hours of sick
          leave on the books, the calculation would be as follows:
          1.  They would still officially leave the company on June 5th.
          2.  When the pension is calculated, it would be increased to
              read that they received income until August 14, 1998 (400
              hours divided by 8 hours a day equals 50 days).
          3.  The employee would receive a pension calculated through
              August 14, 1998.

14.7  ACCIDENTAL LIFE INSURANCE: All employees covered by this Agreement will be
      covered by an accidental death and dismemberment policy in the amount of

      an aircraft either fixed wing or helicopter, and while traveling on
      Company business. Benefits from this policy shall be in addition to any
      other insurance plan.

14.8  LONG-TERM DISABILITY INSURANCE: The Company will provide a long term
      disability (LTD) plan, to extend disability benefits at a reduced rate
      upon termination of benefits described in Article 14.2 (JOB INCURRED
      INJURIES/SALARY PROTECTION) or 14.4 (SHORT TERM DISABILITY BENEFIT) above.
      Premiums for such coverage will be paid for by the employee, through
      payroll deduction. All administrative expenses, exclusive of carrier
      expense normally absorbed in the rates, will be borne by the Company.

            computed at the employee's regular rate for a forty (40) hour, seven
            (7) day period.

          . Supplemental payments shall be made for the first day recognized by
            the Workers Compensation Insurance Plan and shall terminate with the
            date of the last day of disability recognized by the Workers
            Compensation Insurance Plan, as evidenced by the remittance portion
            of the disability check from the Workers Compensation Insurance
            Plan, which must be presented to the Company, for a maximum period
            of benefits as defined in the following schedule of benefits, for
            any one accident regardless of the various periods of disability
            which may be compensated for the one accident.

                                       MAXIMUM           PERCENT OF
                    LENGTH            PERIOD OF             BASE
                  OF SERVICE          BENEFITS            EARNINGS
                  ----------          --------            --------

                  6 months            13 weeks               55
                  5 years             26 weeks               60
                  10 years            52 weeks               65
                  15 years            60 weeks               70
                  20 years            65 weeks               75

          . For a job incurred disability of less than five (5) days which does
            not qualify for Workers Compensation Insurance Plan compensation,
            employees must use any accrued sick leave, and upon exhaustion of
            such accrued sick leave shall receive disability benefits as defined
            above. Any medical absence of five (5) calendar days or more related
            to a work related injury or illness will only be paid by the Workers
            Compensation Plan; not with accrued sick leave.

          . No supplemental disability payments shall be made for any disabling
            accident caused by the injured employee's violation of any safety
            rule.

          . Any employee who performs activities for which compensation is
            received or which exceed the scope of the prescribed physical
            limitation pertaining to such disability while receiving disability
            compensation described in this section, shall forfeit his
            entitlement to all disability benefits and his employment shall be
            terminated.

14.11 JOB INCURRED INJURY/PARTIALLY DISABLED EMPLOYEES: When, in the opinion of
      the Company's doctor after consultation with the employees' doctor,
      regular employees with at least one (1) year of Company service cannot
      perform their regular work because of partial disability, but can perform
      other work, the following plan shall be applicable:

      Each case shall be considered on its merits by a committee consisting of
      the Business Manager of the Union and the Director of Employee Relations,
      or their designated representative, and two (2) additional members, one
      (1) of whom shall be designated by the Union and the other by the Company.
      The committee shall have the authority to waive the seniority and bidding
      provisions of this Agreement in order to place the disabled employee, and
      it shall determine the seniority rights of such employee. This committee
      may call on anyone who may be able to furnish pertinent information.

      In no event will this Article apply if the employee's disability occurs
      while self-employed or working for others, for remuneration (except on
      Union business), or is involved in misconduct or an extreme violation of
      Company safety rules.

      The panel shall complete an evaluation of the type of work the employee is
      able to perform or may be able to perform in the future. Evaluation of the
      employee's capabilities may include but shall not be limited to a physical
      examination and doctors' reports, the employee's physical and mental
      ability, willingness to work, and trainability.

      Depending upon the evaluation of the employee and where necessary and
      practical, the Company shall provide job related education and training.
      The panel shall also conduct periodic review of these cases to determine
      if an employee's condition has changed; if the employee's condition has
      changed, the panel will reevaluate the employee's job assignment.

      The panel will determine the job classification which is appropriate for
      the work the employee is able to perform, as well as the proper pay rate,
      taking into account the new classification pay rate or the rate indicated
      on the following schedule, whichever is greater.

      Years Of Company Service               A Pay Rate That Is Not Less Than
      ------------------------               --------------------------------
        1 to 4 years inclusive                  70% base rate when injured
       5 to 14 years inclusive                  80% base rate when injured
      15 to 24 years inclusive                  85% base rate when injured
             25 years and over                  90% base rate when injured

      As long as such employee is paid more than the maximum rate for the job
      classification in which the employee is placed, the employee shall receive
      only fifty (50) percent of any base wage increase or lump sum payment in
      lieu of a base wage increase. Such fifty (50) percent shall be calculated
      on the employee's personal rate at the time of the increase.

      The placing of a disabled employee in a different job shall not constitute
      an increase in the Company's normal work force. However, the Company may
      temporarily increase the number of authorized positions to accommodate an
      individual when a future vacancy is clearly defined and recognizable.

                                   Page #48


      If the committee is unable to place an individual in accordance with these
      provisions they would be eligible for vocational rehabilitation training,
      and benefits through the State Industrial Insurance System. Upon this
      determination, the individual's employment with the Company will be
      terminated, and any accrued benefits will be paid at the time of
      termination.

      The parties agree that the provisions of this Article may be suspended
      with sixty (60) days written notice, documenting the reasons for this
      request and the interests which would need to be addressed for the
      continuance of this program.

14.12 SHORT TERM DISABILITY BENEFIT: A regular employee, or a temporary employee
      who has worked more than one thousand forty (1040) straight time hours who
      shall suffer any disabling illness or injury while not in work status,
      shall be entitled to disability payments in such amounts and under such
      conditions as described herein:

          . An eligible employee shall be entitled to receive payments not to
            exceed the percent of the employee's weekly straight time earnings,
            such earnings to be computed on the employee's regular rate for a
            forty (40) hour, seven (7) day period, for a maximum period of
            benefits at the percent of earnings as defined in the following
            schedule of benefits.

                                    MAXIMUM         PERCENT OF
                   LENGTH          PERIOD OF           BASE
                 OF SERVICE        BENEFITS          EARNINGS
                 ----------        --------          --------

                  6 months*        13 weeks             55
                   5 years         26 weeks             60
                  10 years         52 weeks             65
                  15 years         60 weeks             70
                  20 years         65 weeks             75

          * Employees in this category may be granted up to thirteen (13)
            additional weeks of leave without pay for continued disability.

          . No disability payments for an illness shall be made until at least a
            three (3) days waiting period has been observed, however, an
            employee must use accrued sick leave to satisfy the waiting period
            or to extend the waiting period to the maximum of the amount of
            accrued sick leave.

          . Any female employee who becomes pregnant and is unable to work shall
            be entitled to disability benefits under this Article, as described
            above, subject to the following conditions. She must present a
            document from her attending physician saying that she is under the
            doctor's care because of the pregnancy and is unable to work. The
            period of the disability shall begin at least three (3) days after
            the attending physician declares the employee disabled and shall end
            when the employee is no longer disabled as determined by the
            attending physician. Pregnant employees must use all accumulated
            sick leave before disability payments will start. A female employee
            will not be eligible for pregnancy related disability

                                   Page #49


            benefits except for her own disability. An employee who is on
            maternity leave and recovering from disability may request to have
            her leave extended for up to three (3) months after termination of
            pregnancy for child care or other reasons.

          . Any employee who performs activities for which compensation is
            received or which exceed the scope of the prescribed physical
            limitation pertaining to such disability while receiving disability
            compensation described in this section, shall forfeit their
            entitlement to all disability benefits and their employment shall be
            terminated.

          . Any employee who returns to work in a light-duty status from short-
            term disability will not create a new benefit eligibility until they
            have had a full-duty release and worked for thirty (30) calendar
            days from the time of that release. If an employee returns to short-
            term disability without satisfying this requirement, their short-
            term disability benefit will reflect their prior usage and continue
            until expiration of such benefits.

          . Any employee who is unable to perform the duties of their position
            as a result of a non-job-incurred injury, would be considered for
            any vacancy for which they are qualified. If awarded a position in
            accordance with Article 7 (SENIORITY AND PROMOTIONS), the employee
            would receive the appropriate rate of pay for that position.

          . Any employee that exhausts their short-term disability benefit and
            is unable to return to work at that time, may request one unpaid
            leave of absence for up to ninety (90) days to allow time for
            further recuperation or possible vacancies for which they are
            qualified. Such employees will be allowed to continue their medical
            coverage at the appropriate COBRA rate for this period of time. If
            this individual is unable to return to work at the expiration of
            this unpaid leave, their employment with the Company will be
            terminated and all accrued benefits will be paid at the time of
            termination.

14.13 RETIREMENT BENEFIT: The Nevada Power Company Retirement Plan, a defined
      benefit pension plan bearing No. 003, including the amendments dated March
      5, 1980, shall be incorporated by reference into this Agreement. The
      Company has, since January 1, 1976, been paying the entire cost of this
      retirement plan. All participants in the pension plan which was in effect
      before January 1, 1976, have and are guaranteed all accrued benefits under
      that pension plan as computed on December 31, 1975.

      Effective February 1, 1990, the pension plan was amended to delete the
      provision that the selection of a surviving spouse benefit will revert to
      a single life annuity if the spouse predeceases the retired employee.

      Effective February 1, 1994, the pension plan was improved to provide for
      early retirement benefit reductions of 5% per year from age sixty-two
      (62).

      Effective January 1, 1989, the pension plan was changed from a social
      security offset plan to a step rate plan. Effective February 1, 1998, the
      formula for calculating benefits will be 1.35% of final five-year average
      earnings up to Social Security Covered Compensation, plus 1.8% of final
      five-year average

                                   Page #50


     earnings exceeding covered compensation, times service up to 35 years, plus
     1.35% of final five-year average earnings, times service over 35 years. For
     this purpose, final five-year average earnings is the average of the
     highest sixty (60) consecutive months of earnings.

     Effective February 1, 2001, the formula for calculating benefits will be
     1.365% of final five-year average earnings up to Social Security Covered
     Compensation, plus 1.8% of final five-year average earnings exceeding
     covered compensation, times service up to 35 years, plus 1.365% of final
     five-year average earnings, times service over 35 years. For this purpose,
     final five-year average earnings is the average of the highest sixty (60)
     consecutive months of earnings.

     Effective February 1, 1987, entry into the pension plan shall be on the
     first day of the month coincident with, or following completion of one year
     of service and attainment of age twenty-one. Participants in the plan prior
     to February 1, 1987, shall enter the plan on the first day of the month
     coincident with, or following completion of one (1) year of eligibility
     service and attainment of age twenty-one, unless those participants had
     declined enrollment under the eligibility rules in effect when they had
     first become eligible.

     Effective February 1, 1987, vesting service shall be measured from the
     employee's date of hire or age eighteen, whichever is later. The Company
     shall make such modifications in the plan as may be required by 1) the
     Internal Revenue Service in order to qualify said benefits under the
     applicable provisions of the Internal Revenue Code and/or related rules and
     regulations; or 2) any other governmental agency having jurisdiction. Other
     modifications may be made as needed but in no event shall any benefits be
     reduced during the term of this Agreement.

     Effective February 2, 1998, all sick leave accrued at time of retirement
     will be added to the years of service for fully vested participants only.

          -----------------------------------------------------------
                                    Example
                                    -------

          If an employee retires June 5, 1998 and has 400 hours of
          sick leave on the books, the calculation would be as
          follows:
          4. They would still officially leave the company on June
             5/th/.
          5. When the pension is calculated, it would be increased to
             read that they received income until August 14, 1998
             (400 hours divided by 8 hours a day equals 50 days).
          6. The employee would receive a pension calculated through
             August 14, 1998.
          -----------------------------------------------------------

14.14  401(K) CONTRIBUTION/COMPANY MATCH: In accordance with 401(k)
       documentation, effective January 1, 1999, the Company will provide a
       matching contribution of 55 cents of the employee's contribution, to a
       maximum of 7% of gross income, to the Nevada Power Company 401(k) plan.
       Company contributions will be invested in Nevada Power Company stock.

       Effective on February 1, 1999, the Company will provide a matching
       contribution of 60 cents of the employee's contribution, to a maximum of
       7% of

       contributions will be invested in Nevada Power Company stock.

       Effective on January 31, 2000, the Company will provide a matching
       contribution of 60 cents of the employee's contribution, to a maximum of
       8% of gross income, to the Nevada Power Company 401(k) plan. Company
       contributions will be invested in Nevada Power Company stock.

       Effective on January 29, 2001, the Company will provide a matching

       contributions will be invested in Nevada Power Company stock.

14.15  ACCIDENTAL LIFE INSURANCE: All employees covered by this Agreement will
       be covered by an accidental death and dismemberment policy in the amount
       of $50,000. This policy shall apply only when an employee is a passenger
       in an aircraft either fixed wing or helicopter, and while traveling on
       Company business. Benefits from this policy shall be in addition to any
       other insurance plan.

14.16  LONG-TERM DISABILITY INSURANCE: The Company will provide a long term
       disability (LTD) plan, to extend disability benefits at a reduced rate
       upon termination of benefits described in Article 14.2 (JOB INCURRED
       INJURIES/SALARY PROTECTION) or 14.4 (SHORT TERM DISABILITY BENEFIT)
       above. Premiums for such coverage will be paid for by the employee,
       through payroll deduction. All administrative expenses, exclusive of
       carrier expense normally absorbed in the rates, will be borne by the
       Company.

                                ARTICLE NO. 15
                               Leaves of Absence

15.1   SHORT TERM LEAVES: Provided the needs of the Company will permit, time
       off without pay for any period of thirty (30) calendar days or less may
       be granted employees upon a written application to their department head
       showing good and sufficient reason for such request. This shall not be
       construed as a leave of absence without pay, as the term is used in this
       Agreement. A leave of absence without pay is defined as a period of
       authorized absence from service in excess of thirty (30) days.

15.2   JUSTIFICATION: Leaves of absence shall be granted to regular employees
       for urgent substantial personal reasons, provided adequate arrangements
       can be made to take care of the employee's duties without undue
       interference with the normal routine of work. Leave will not be granted
       if the purpose for which it is requested may lead to the employee's
       resignation.

15.3   DURATION: A leave shall commence on and include the first work day on
       which an employee is absent and terminate with and include the work day
       preceding the day the employee's leave expires. The conditions under
       which an employee shall be restored to employment on the termination of
       his leave of absence shall be clearly stated by the Company on the form
       on which application for leave is made.

15.4   SENIORITY: Except as otherwise provided herein, an employee's seniority
       shall not accrue while on leave without pay. However, an employee's
       status as a regular employee shall not be impaired by a leave of absence.
       Any period of authorized absence without pay for thirty (30) days or less
       shall not affect an employee's seniority status. Upon return from leave,
       an employee shall return to regular status.

15.5   UNION OFFICE: The Company shall, at the request of the Union, grant a
       leave of absence without pay for four (4) years or less to an employee
       who is appointed or elected to any office or position in the Union whose
       services are required by the Union. The seniority of an employee who is
       granted a leave of absence under the provisions of this Section shall
       accrue during the period of such leave. Upon mutual agreement with the
       Union, the Company may extend the leave of the incumbent for additional
       terms up to four (4) years per request. The Company will provide medical
       coverage for this individual at the single coverage rate. This individual
       must make the established monthly employee contribution for health
       coverage.

15.6   PUBLIC OFFICE: Employees elected or appointed to public office shall be
       granted a leave of absence for the duration of such appointment or
       election. Such absence shall not affect accrual rates for seniority
       purposes; however, sick leave and vacation shall not accrue during this
       period and group medical benefits shall be paid by the employee at the
       Company's current premium rate.

                                   Page #53


15.7   MILITARY LEAVE: A leave of absence shall be granted to employees who
       enter the armed forces of the United States, however, any such leave of
       absence and the reinstatement of any such employee shall be subject to
       the terms of the Selective Training and Service Act of 1940, as amended.
       Employees who are members of the armed services who are drafted and are
       called to active duty shall accrue Company seniority while they are
       absent on military duty.

       A regular employee, or a temporary employee who has worked more than one
       thousand forty (1040) straight time hours, who is a member of the armed
       forces reserve units, or the National Guard, and who is required to
       attend annual training sessions, will be granted a leave of absence for
       the duration of such assignment. In addition, the Company will pay such
       employee the amount, if any, by which the remuneration received from the
       government is less than the base straight time earnings the employee
       would have received for the same period, not to exceed eighty (80) hours
       in a calendar year. Such items as subsistence, travel, uniform and other
       allowances will not be included in computing the remuneration received
       from the government. The Company will require satisfactory evidence of
       attendance and remuneration received.

15.8   FAILURE TO RETURN FROM LEAVE: If employees fail to return immediately on
       the expiration of their leave of absence, or if they accept other
       employment while on leave, they shall forfeit the leave of absence and
       terminate their employment with the Company.

15.9   FUNERAL LEAVE: A regular employee, or a temporary employee who has worked
       more than one thousand forty (1040) straight time hours, who is absent
       from duty due to a death in the employee's immediate family will be
       excused without loss of regular pay for the time required not to exceed
       thirty-six (36) hours for making funeral arrangements and attending the

                                ARTICLE NO. 16
                              General Provisions

16.1   SUPERVISORY RESPONSIBILITIES IN EMERGENCY CONDITIONS: It is the intention
       of the Company that supervisors shall generally confine their activities
       to the supervision of the work or operations being performed. In certain
       instances, should emergency conditions arise, it may be necessary for
       them to perform those tasks normally assigned to bargaining unit
       employees. Under ordinary circumstances, such instances will very rarely
       occur, but since the safety of personnel or Company property may be in
       jeopardy, it must remain management's prerogative to determine when
       conditions require the actions described above.

       In the same manner it is the intention of management that the "chain of
       command" be adhered to, by both supervisors and bargaining unit
       employees. However, in the case of emergencies, there will be occasions
       when it may be necessary for a senior supervisor to bypass normal chain
       of command in order to prevent difficulties. Common sense and good
       judgment must be exercised in applying these paragraphs.

16.2   NEW CLASSIFICATIONS/WAGES: Any new rate covering work normally performed
       by employees within the bargaining unit shall first be discussed with the
       Union and the rate established for such work shall be that mutually
       agreeable to both parties.

16.3   REMOVING LETTERS OF DISCIPLINE: Any employee who receives a written
       letter of reprimand which is a part of the personnel file maintained in
       the Company's Human Resources office, may, after three (3) years from the
       date of such letter, request in writing to have the letter removed. Upon
       such written request, the Company shall remove the letter and return it
       to the employee. If the behavior that warranted the letter has changed or
       been corrected, the employee's current supervisor can remove the letter
       from the employee's personnel file by documenting this change in behavior
       and providing written authorization to human resources.

16.4   FACILITIES: The Company will provide on its premises clean, sanitary and
       reasonably comfortable rest and wash rooms, including first aid cots for
       female employees, together with a proper place for storing lunches
       carried by employees, and reasonably safeguarding employee's out-of-door
       clothing and necessary personal effects on the Company's property during
       the time employees are on duty. The Union agrees to cooperate with the
       Company in the maintenance of these facilities.

16.5   HEALTH AND SAFETY: The parties hereto agree to cooperate in using all
       reasonable means to eliminate conditions of danger to either the general
       public, the Company or its employees. No employee shall knowingly engage
       in an unsafe act.

                                   Page #56


       Whenever it becomes necessary to employ day shift employees assigned to
       the Company's business offices, where security personnel are assigned,
       outside the normal work hours, and such work is during the hours of
       darkness, all arrivals and departures from Company owned parking
       facilities shall be observed and controlled by security personnel.
       Parking facilities shall, when possible, be adjacent to the Company's
       business offices.

       The Company agrees to furnish such safety devices and equipment including
       first aid kits, as may be reasonable and necessary for the health and
       safety of its employees, and the Union agrees, on behalf of the
       employees, that such equipment will be used.

16.6   LABOR/MANAGEMENT MEETINGS: The parties agree to hold periodic meetings to
       discuss matters which are covered by the Agreement. These meetings will
       be held on Company premises during work time and shall, where possible,
       be scheduled mutually each sixty (60) days. The number of employee
       attendees who are covered by the agreement shall be limited to the
       stewards and other employees reporting to the Company premises designated
       as the site of a particular meeting.

16.7   UPGRADE: When an employee relieves an employee of a higher
       classification, the employee shall receive the rate of pay for the higher
       classification for the time worked in the higher classification. However,
       an employee will not be upgraded when employees of that classification
       who normally report for work at the same location are able and available
       to do the work for which the upgrade is intended.

       All red circle employees when upgraded to Lead positions will receive a
       5% wage increase for any time worked in this position.

       All employees when upgraded for an authorized training capacity will
       receive a 5% wage increase for any time worked in this position.

       place, so far as possible, in the sixty (60) day period prior to the end
       of the then current term. Failure of the parties to agree on such
       proposed amendment or revision shall not cause termination of this
       Agreement unless either party has given notice of termination as provided
       in Section 1 above.

17.3   PROVISIONS IN CONFLICT WITH THE LAW: In the event that any provision of
       this Agreement shall at any time be made invalid by applicable
       legislation, or be declared invalid by any court of competent
       jurisdiction, such action shall not invalidate the entire Agreement, it

       made invalid shall remain in full force and effect.

     I, _________________________________________________, herewith authorize
               (print name)         (employee no.)
Nevada Power Company to deduct initiation and/or reinstatement fees and monthly
dues owing to the Union, in accordance with the Constitution and By-Laws of the
Union, and direct such amounts so deducted be sent to the Secretary-Treasurer of
the Union for and on my behalf.

     When the full amount of the initiation or reinstatement fee has been
withheld from my earnings, such authorization for deduction of initiation or
reinstatement fee only shall be null and void, and shall thereafter have no
further force or effect.

     This authorization shall be irrevocable for the period of the applicable
agreement between the Union and the Company, or for one (1) year, whichever is
lesser, and shall automatically renew itself for successive yearly or applicable
agreement periods thereafter, whichever is lesser, unless I give written notice
to the Union, registered, Return Receipt Requested, of my desire to revoke the
same. The Union will notify the Company on a biweekly basis if necessary of
those employees who wish to revoke this deduction; such deductions will cease in
the pay period following receipt of such notice from the Union.

     It is recognized that neither the Company nor the Union shall be under any
liability to me, the undersigned, with respect to the deductions provided
herein.

                             SICK LEAVE AGREEMENT

INTRODUCTION
The Union agrees to share the responsibility in protecting the sick leave plan
from abuses by any of its members, recognizing that the plan is intended to
provide pay coverage under situations of actual need.

MEDICAL ATTENTION
Sick leave may be used for obtaining medical information or treatment including
exams or treatments for care of the eyes or teeth of eligible employees. Such
absences should be approved in advance where possible and limited to the time
necessary for treatment or examination or recovery.

ALCOHOL AND DRUG ABUSE
An employee who seeks professional treatment to correct a problem of excessive
use or dependence on an alcohol or other controlled substances will be placed on
medical leave of absence for such treatment. Available unused sick leave may be
used while under professional treatment. Arrangements for treatment must be made
with the EAP Provider and the Company and such treatments will be kept as
confidential as possible. Employees who receive such treatment will be expected
to observe all conditions and attend all meetings which are required as part of
the total rehabilitation program. Evidence of abstinence may be required as a
follow-up and negative findings may result in termination.

                                   EXHIBIT V
                          TEMPORARY LAYOFF PROVISIONS

The following provisions shall apply relative to a temporary layoff, as
referenced in Article 5.4 (LAYOFF PROVISIONS):

NOTIFICATION: Should the Company initiate a temporary layoff, affected employees
shall be notified in writing as soon as possible, and will have three (3) days
to indicate their interest for consideration in the layoff.

ELIGIBILITY: Temporary layoffs, out of line of seniority, shall be strictly
voluntary. If there are more volunteers than needed within a classification,
selection shall be determined by highest Company seniority of the interested
employees. If there are no volunteers, the Company shall explore other
alternatives that may satisfy the temporary layoff situation.

TIME FRAME: A temporary layoff shall be for the stated time period or less, as
indicated in writing at the time of notification. If, during the temporary
layoff, the Company recognizes that the layoff may extend beyond the original
time frame, employees in layoff status shall be given the option to extend or
return to work. If the temporary layoff ends before the stated time frame,
employees will be notified immediately, and expected to return to work the next
day unless other arrangements are approved by management.

PAY: Employees shall be paid approximately 70% of their current income, which
includes income received from unemployment compensation as a result of the
layoff. The following formula shall be used to calculate an employee's gross
wages while on temporary layoff:

    Base rate  x  40 Hrs.  x  70% -  Unemployment Income  =  Weekly Gross Wages

For the purpose of this calculation, the unemployment compensation amount will
be subtracted to arrive at gross wages even if the employee does not receive
this benefit. The exception to this provision will be for the first week of the
temporary layoff, when employees will be required to serve a waiting week for
unemployment compensation. For this initial week, employees will be paid 70% of
their base rate.

VACATION: No adjustment to vacation accrual shall be made during the first sixty
(60) calendar days of a temporary layoff. However, once the sixty (60) day
period has elapsed, an employee's vacation accrual shall be adjusted and treated
as any other leave, as outlined in Article 12.4 (VACATION ADJUSTMENTS). If
employees are in layoff status and unable to use their vacation allotment for
that year, the unused vacation shall be automatically carried over to the next
year.

SICK LEAVE: Employees shall continue to accrue sick leave monthly, as if they
were working. However, employees will not be eligible to use sick leave or
short-term disability during the period for which they are on temporary layoff.

                                   Page #72


HOLIDAYS: Employees shall not be entitled to holiday pay while on temporary
layoff. The only situation that would warrant holiday pay is if they began or
were recalled from temporary layoff during the week of a holiday.

                                    EXAMPLE
                                    -------

           if the temporary layoff begins on tuesday of a week with a
           monday holiday, the employee would receive holiday pay for
           that day.

These provisions do not apply to the floating holiday, as the employee would be
allowed to reschedule the day at a future time. If as a result of a temporary
layoff, an employee is unable to schedule their floating holiday, they will be
allowed to carry this holiday into the following year.

SENIORITY: An employee's seniority shall continue to accrue during the period of
layoff.

BENEFITS: An employee's benefits shall remain the same during the period of
layoff. Employees monthly contribution will be deducted from these bi-weekly
checks.

PROMOTIONAL OPPORTUNITIES: Employees shall be eligible to indicate their
interest in promotional opportunities that may arise during the period of
layoff. However, they must individually assume the responsibility of meeting
appropriate deadlines for consideration. Any employee awarded a promotion or
transfer while on temporary layoff, will be returned to work immediately.

RECALL: Should the Company need to recall employees in a specific classification
prior to the previously stated date, employees shall be recalled by Company
seniority on a volunteer basis. If there are no volunteers to return, inverse
seniority will be used to satisfy these requirements. Any issues delaying an
employee's return to work will be addressed on an individual basis. However, the
monetary benefits associated with a temporary layoff will end on the date of
recall.

Electrical Workers, Local 396

Las Vegas, NV 89121

LETTER OF UNDERSTANDING - ARTICLE 14.4
- --------------------------------------

Dear Mr. Brimer:

Prior to January 1, 1976, employee participants in the Nevada Power Company
Retirement Plan were required to contribute slightly less than 3% of their
straight time earnings to defray the Company cost of retirement benefits.
Effective January 1, 1976, the Company paid the full cost of the retirement
benefits plan.

On January 1, 1988, twenty-eight (28) employees covered by the Clerical
Collective Bargaining Agreement were active employees and had made contributions
toward their retirement benefits. Records have been maintained on the amount of
each of the twenty-eight (28) employees showing the accumulation of the direct
contributions made by these employees and the earnings, through investments on
their contributions through December 31, 1975. The Company has, in accordance
with IRS regulations, agreed to credit the 12/31/75 account balances with five
percent (5%) interest per year until disposition of these funds was made
individually with each of these employees.

The Company has now agreed to standardize the retirement plans in the area of
funding for retirement benefits. To standardize, the Company has agreed to
return monies contributed prior to January 1, 1976, by the twenty-eight (28)
employees to the employees plus earnings and interest at five percent (5%) per
year if the employee requests return. The Company is permitting the selection of
several options which are described in the following paragraphs:

OPTION I:     Participants in the Nevada Power Company Retirement and Thrift
EMPLOYEE      Plan actively employed on January 1, 1988, may elect to receive
- --------
CONTRIBUTION  their employee contribution to the Plan, along with
- ------------        --------
              earnings and interest, computed at 5% per annum from
              January 1, 1976 through April 30, 1988. If the
              employee's contributions are withdrawn, the monthly
              benefit that is calculated using final average earnings,
              credited service and social security benefit will not be
              reduced.

                                   Page #75


OPTION II:    At the time of termination or retirement, Participants  in the
EMPLOYEE      Nevada Power Company  Retirement and Thrift Plan actively employed
- --------
CONTRIBUTION  on January 1, 1988, may choose to leave their employee
- ------------                                                --------
              contributions in the Plan, along with earnings and interest
              computed at 5% per annum from January 1, 1976, until retirement or
              termination from Nevada Power Company and receive a lump sum
              payment of their employee account at that time. This withdrawal of
              the employee's contributions will not reduce his monthly benefit.
                                                ---

OPTION III:   At the time of termination or retirement, participants in Nevada
EMPLOYER      Power Company Retirement  and Thrift Planer actively employed on
- --------
CONTRIBUTION  January 1, 1988, may elect to withdraw the employer contribution
- ------------                                             --------
              to the Plan which will include interest computed at 5% per annum
              from January 1, 1976, until the date of termination or retirement.
              This election will be available whether they have withdrawn the
              employee contribution in 1988 or at the time of termination. If
              the employer's contribution is withdrawn, the employee's annuity
              would be reduced by an equivalent amount calculated by
              accumulating the total employer account value with 5% interest to
              normal Retirement Date dividing by 120 and multiplying by the
              ratio of actual years of credited service to years of credited
              service at normal retirement.

OPTION IV:    Participants in the Nevada Power Company Retirement and Plan
EMPLOYER      actively employed elect to leave the employer's contribution in
- --------
CONTRIBUTION  the Plan, along ted at 5% per annum from January 1, 1976, until
              the date. If the employer's contribution is not withdrawn, there
              will be no reduction of the employee's monthly benefit.

DISCIPLINE RELATIVE TO TARDINESS AND ATTENDANCE

Dear Mr. Anzinger:

Both the Company and Union recognize that having reliable employees with good
attendance is central to achieving the Company's goals and mission. Both parties
also recognize that the majority of employees have good attendance records and
display a true commitment to their occupation and work groups. However, in an
effort to assist those employees who may have an attendance problem and minimize
the burden placed on fellow employees, the Company and Union have agreed to
waive the time off the job (i.e. one (1) day suspension, three (3) day
suspension) and document those steps of progressive discipline on paper only.

It is incumbent on both parties to communicate that although employees will not
be subject to lost time, this should in no respect minimize the seriousness of
this action. This agreement will remain in effect until February 1995, at which
time the Company and Union will reconvene to discuss extending or discontinuing
this agreement.

VACATION/SICK LEAVE BONUS

Dear Mr. Anzinger:

During negotiations of the Plant agreement, which expires in February 1994, both
the Company and Union recognize that our ability to succeed in a competitive
environment is the result of effectively utilizing material and human resources.
As such, in an effort to minimize increases in manpower resulting from scheduled

consideration by employee's eligible for the vacation and sick leave bonus.
Issues relative to a buy-out in the form of Company stock placed in the

ORGANIZATION STUDY


Dear Mr. Anzinger:

In May of 1993, the Board of Directors provided the necessary approval for the
Company to begin on an Organization Study. This study has provided us with an
opportunity to take a fresh look at Nevada Power Company, assess the way our
work is organized to provide faster, more efficient service to our customers,
and evaluate the way we communicate with each other to resolve problems more
efficiently.

During the negotiations of the Clerical agreement, which expires in May of 1994,
the Company and Union agreed that as the Company streamlines work processes,
there will be occasions which will require the Company and Union to reconvene to
discuss issues of flexibility, changes in technology, and maximizing resources.
Both parties recognize that changes promoting efficiencies in the work place
benefit all employees, and the Company and Union will continue to promote and
support ideas that meet those interests.

FLEX SCHEDULING

Dear Mr. Anzinger:

This is to confirm our agreement made relative to flex scheduling and
establishing a program which is available to all departments in the Company
(Plant & Clerical Agreements).

With prior approval of immediate supervision, regular employees will be allowed
flexibility in the starting and quitting times of their regularly scheduled
eight (8) hour shifts. The purpose of the program is to enable employees to
attend to family, medical, community and other needs which may occasionally
arise by reporting to work later than scheduled or leaving work earlier than
scheduled, and to make up the scheduled time not worked.

The program will be administered subject to service requirements of the Company
and the following conditions:

1.   An employee who works less than a regular scheduled shift will be paid only
     for the time actually worked on that shift.

2.   Make-up hours must be worked within the work week in which a flex schedule
     is granted. Also, make-up hours shall not be denied once the flex time has
     been taken off.

3.   Corresponding make-up hours shall be reflected as such in the employee's
     time card.

4.   No more than twenty (20) flex hours will be allowed in any thirty (30) day
     period.

5.   Make-up hours available but not worked within the work week will be treated
     as an unpaid absence and shall be subject to the attendance policy.

6.   Employees may use vacation time as make-up time with supervisory approval.

7.   Make-up hours will be paid at straight time regardless of the shift or day
     on which they are worked.

No grievance will be filed asserting that the program violates any provision of
the Labor Agreement which may conflict or be inconsistent with the program.

                                   Page #84


This agreement will remain in effect from September 28, 1995 through February 2,
1998, unless canceled in writing by either the Company or the Union with two (2)
week's notice.

Dear Mr. Anzinger:

This letter will document an agreement between the International Brotherhood of
Electrical Workers (IBEW), Local #396, and Nevada Power Company regarding
assignments within Telephone Service Operations (TSO).

As job functions within TSO become available, TSO employees will be asked to
indicate interest for those functions through a "show of interest" process.
Information regarding the available function will be published, including:
function, shift, description of major duties, skills and knowledge, deadline and
means for responding to the show of interest. All TSO employees who indicate an
interest will be considered for assignment based on skills, knowledge and
Company seniority. When knowledge and skills are substantially equivalent,
Company seniority shall govern.

This process for assigning functions within the TSO will remain in effect until
such time that either party gives written notice to the other party of its
desire to discontinue this process. This process will then be discontinued and
all vacancies that arise subsequently will be filled in accordance with the
applicable job posting system in effect at that time.

LETTER OF AGREEMENT:
- -------------------

RECLASSIFICATION OF RETAIL OPERATIONS REPRESENTATIVES (ROR)

Dear Mr. Anzinger:

This letter will document the agreement between the International Brotherhood of
Electrical Workers, Local #396 (IBEW), and Nevada Power Company (NPC) relative
to the Retail Operations Representative classification.

In a Letter of Understanding dated August 20, 1996, between NPC and IBEW, the
ROR classification was created. This letter confirms our agreement that the ROR
classification and associated duties have been eliminated. However, the duties
performed by these employees prior to the creation of the ROR classification
will remain under the jurisdiction of the IBEW.

All ROR's will be reclassified as Retail Customer Representatives (RCR)
effective immediately. The Company will notify ROR's in advance of the
reclassification. Following their reclassification to RCR, NPC may transfer them
to the Telephone Service Operations by inverse seniority. The employees affected
will maintain their seniority and wages.

Very truly yours,



Gloria Banks Weddle
Vice President, Corporate Services

AGREED:

James Anzinger
Business Manager and Financial Secretary
IBEW Local #396
