                             SCG HOLDING CORPORATION
           2000 EMPLOYEE STOCK PURCHASE PLAN (AS ADOPTED BY THE BOARD
                   OF DIRECTORS ON FEBRUARY 17, 2000; AMENDED
                          AND RESTATED APRIL 21, 2000)

         1. PURPOSE. The purpose of this SCG Holding Corporation 2000 Employee
Stock Purchase Plan (the "Plan") is to encourage stock ownership by eligible
employees of SCG Holding Corporation (the "Company") and its Subsidiaries and
thereby provide employees with an incentive to contribute to the profitability
and success of the Company. The Plan is intended to qualify as an "employee
stock purchase plan" under Section 423 of the Code and will be maintained for
the exclusive benefit of eligible employees of the Company and its Subsidiaries.

         2. DEFINITIONS. For purposes of the Plan, in addition to the terms
defined in Section 1, the following terms are defined:

                  (a) "Board" means the Board of Directors of the Company.

                  (b) "Cash Account" means the account maintained on behalf of a
Participant by the Company for the purpose of holding cash contributions
withheld from payroll pending investment in Stock.

                  (c) "Code" means the Internal Revenue Code of 1986, as
amended.

                  (d) "Custodian" means Solomon Smith Barney or any successor or

including bonuses, for services performed for the Company and its Subsidiaries
and received by a Participant for services rendered during an Offering Period.

                  (f) "Fair Market Value" means the closing price of the Stock
on the relevant date as reported on NASDAQ (or any national securities exchange
or quotation system on which the Stock is then listed), or if there were no
sales on that date the closing price on the next preceding date for which a
closing price was reported; provided, however, that for any Offering Period
beginning on the IPO Date, the Fair Market Value of the Stock on the first day
of such Offering Period shall be deemed to be the price at which the Company's
Stock is offered under its initial public offering of Stock.

                  (g) "IPO Date" means the date on which the Company's initial
public offering of Stock is consummated.

                  (h) "Offering Period" means the period beginning on the IPO
Date and ending on the last day of the next calendar quarter, and every
three-month period thereafter. For Participants who do not reside in the United
States, if the day on which the Company receives approval by the applicable
foreign jurisdiction to offer common stock to Participants residing in that
jurisdiction is later than the day on which the Company's initial public
offering becomes effective, the Offering Period means the period beginning on
the day on which the Company

                                                                               1

receives approval by the applicable foreign jurisdiction to offer common stock
to such Participants and ending on the last day of the next calendar quarter,
and every three-month period thereafter.

                  (i) "Participant" means an employee of the Company or a
Subsidiary who is participating in the Plan.

                  (j) "Purchase Right" means a Participant's option to purchase
Stock that is deemed to be outstanding during an Offering Period. A Purchase
Right represents an "option" under Section 423 of the Code.

                  (k) "Stock" means the common stock of the Company.

                  (l) "Stock Account" means the account maintained on behalf of
the Participant by the Custodian for the purpose of holding Stock acquired under
the Plan.

                  (m) "Subsidiary" means any corporation (other than the
Company) in an unbroken chain of corporations beginning with the Company if each
of the corporations (other than the last corporation in the unbroken chain) owns
stock possessing 50% or more of the total combined voting power of all classes
of stock in one of the other corporations in the chain as set forth in Code
Section 424(f).

         3. ADMINISTRATION.

                  (a) Board Administration. The Plan will be administered by the
Board. The Board may delegate its administrative duties and authority (other
than its authority to amend the Plan) to any Board committee or to any officers
or employees or committee thereof as the Board may designate (in which case
references to the Board will be deemed to refer to the administrator to which
such duties and authority have been delegated). The Board will have full
authority to adopt, amend, suspend, waive, and rescind rules and regulations and
appoint agents as it deems necessary or advisable to administer the Plan, to
correct any defect or supply any omission or reconcile any inconsistency in the
Plan and to construe and interpret the Plan and rules and regulations
thereunder, to furnish to the Custodian such information as the Custodian may
require, and to make all other decisions and determinations under the Plan
(including determinations relating to eligibility). No person acting in
connection with the administration of the Plan will, in that capacity,
participate in deciding any matter relating to his or her participation in the
Plan.

                  (b) The Custodian. The Custodian will act as custodian under
the Plan, and will perform duties under the Plan and in any agreement between
the Company and the Custodian. The Custodian will establish and maintain
Participants Stock Accounts and any subaccounts as may be necessary or desirable
to administer the Plan.

                  (c) Waivers. The Board may waive or modify any requirement
that a notice or election be made or filed under the Plan a specified period in
advance on an individual case or by adopting a rule or regulation under the
Plan, without amending the Plan.

                                                                               2
<PAGE>   3
                  (d) Other Administrative Provisions. The Company will furnish
information from its records as directed by the Board, and such records,
including a Participant's Earnings, will be conclusive on all persons unless
determined by the Board to be incorrect. Each Participant and other person
claiming benefits under the Plan must furnish to the Company in writing an
up-to-date mailing address and any other information as the Board or Custodian
may reasonably request. Any communication, statement, or notice mailed with
postage prepaid to any such Participant or other person at the last mailing
address filed with the Company will be deemed sufficiently given when mailed and
will be binding upon the named recipient. The Plan will be administered on a
reasonable and nondiscriminatory basis and uniform rules will apply to all
persons similarly situated. All Participants will have equal rights and
privileges (subject to the terms of the Plan) with respect to Purchase Right
outstanding during any given Offering Period in accordance with Code Section
423(b)(5).

         4. STOCK SUBJECT TO PLAN. Subject to adjustment as provided below, the
total number of shares of Stock reserved and available for issuance or which may
be otherwise acquired upon exercise of Purchase Rights under the Plan will be
1,500,000. If, at the end of any Offering Period, the number of shares of Stock
with respect to which Purchase Rights are to be exercised exceeds the number of
shares of Stock then available under the Plan, the Board shall make a pro rata
allocation of the shares of Stock remaining available for purchase in as uniform
a manner as shall be practicable and as it shall determine to be equitable. Any
shares of Stock delivered by the Company under the Plan may consist, in whole or
in part, of authorized and unissued shares or treasury shares or shares of Stock
purchased on the open market. The number and kind of such shares of Stock
subject to the Plan will be proportionately adjusted, as determined by the
Board, in the event of any extraordinary dividend or other distribution,
recapitalization, forward or reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase, or share exchange, or other
similar corporate transaction or event affecting the Stock.

         5. ENROLLMENT AND CONTRIBUTIONS.

                  (a) Eligibility. An employee of the Company or any Subsidiary
designated by the Board may be enrolled in the Plan for any Offering Period if
such employee is employed by the Company or a Subsidiary authorized to
participate in the Plan on the first day of the Offering Period, unless one of
the following applies to the employee:

                           (i)      such person has been employed by the Company
                                    or a Subsidiary less than 90 days; or

                           (ii)     such person is customarily employed by the
                                    Company or a Subsidiary for 20 hours or less
                                    a week; or

                           (iii)    such person is customarily employed by the
                                    Company or a Subsidiary for not more than
                                    five months in any calendar year;

                           (iv)     such person would, immediately upon
                                    enrollment, be deemed to own, for purposes
                                    of Section 423(b)(3) of the Code, an
                                    aggregate

                                                                               3
<PAGE>   4
                                    of five percent or more of the total
                                    combined voting power or value of all
                                    outstanding shares of all classes of the
                                    Stock of the Company or any Subsidiary.

                           Notwithstanding the above, solely for purposes of the
first Offering Period under the Plan, an employee who is employed by the Company
or a Subsidiary on the first day of such Offering Period and who is otherwise
eligible to participate in the Plan shall not be required to satisfy the 90 day
employment period specified in 5(a)(i) above.

                           The Company will notify an employee of the date as of
which he or she is eligible to enroll in the Plan, and will make available to
each eligible employee the necessary enrollment forms. Notwithstanding the
above, any individual who is employed by the Company or a Subsidiary designated
by the Board and who is working outside of the United States shall not be
eligible to participate in the Plan if the laws of the country in which the
employee is working makes the offer of the Purchase Right or the delivery of
Stock under the Plan impractical. Additionally, the offer of the Purchase Right
and the delivery of Stock under the Plan shall be effective for any individual
who is employed by the Company or a Subsidiary and who is working outside of the
United States only after the Company has complied with the applicable laws of
the country in which the employee is working.

                  (b) Initial Enrollment. An employee who is eligible under
Section 5(a) (or who will become eligible on or before a given Offering Period)
may, after receiving current information about the Plan, initially enroll in the
Plan by executing and filing with the Company a properly completed enrollment
form, including the employee's election as to the rate of payroll contributions
for the Offering Period. To be effective for any Offering Period, such
enrollment form must be filed at least two weeks (or such other period
determined by the Board) preceding such Offering Period.

                  (c) Automatic Re-enrollment for Subsequent Offering Periods. A
Participant whose enrollment in, and payroll contributions under, the Plan
continues throughout a Offering Period will automatically be re-enrolled in the
Plan for the next Offering Period unless (i) the Participant terminates
enrollment before the next Offering Period in accordance with Section 7(a), or
(ii) the Participant is ineligible to participate under Section 5(a). The
initial rate of payroll contributions for a Participant who is automatically
re-enrolled for a Offering Period will be the same as the rate of payroll
contribution in effect at the end of the preceding Offering Period, unless the
Participant files a new enrollment form designating a different rate of payroll
contributions and such new enrollment form is received no later than two weeks
(or such other period determined by the Board) prior to the beginning of the
next Offering Period.

                  (d) Payroll Contributions. A Participant will make
contributions under the Plan by means of payroll deductions from each payroll
period which ends during the Offering Period, at the rate elected by the
Participant in his or her enrollment form in effect for that Offering Period
(except that such rate may be changed during the Offering Period to the extent
permitted below). The rate of payroll contributions elected by a Participant may
not be less than one percent (1%) nor more than ten percent (10%) of the
Participant's Earnings for each payroll period, and only whole percentages may
be elected; provided, however, that the Board may

                                                                               4
<PAGE>   5
specify a lower minimum rate and higher maximum rate, subject to Section 8(c).
Notwithstanding the above, a Participant's payroll contributions will be
adjusted downward by the Company as necessary to ensure that the limit on the
amount of Stock purchased for an Offering Period set forth in Section 6(a)(iii)
is not exceeded. A Participant may elect to increase, decrease, or discontinue
payroll contributions for a future Offering Period by filing a new enrollment
form designating a different rate of payroll contributions, which form must be
received at least two weeks (or such other period determined by the Board) prior
to the beginning of an Offering Period to be effective for that Offering Period.
In addition, a Participant may elect to discontinue payroll contributions during
an Offering Period by filing a new enrollment form, such change to be effective
for the next payroll after the Participant's new enrollment form is received.

                  (e) Crediting Payroll Contributions to Cash Accounts. All
payroll contributions by a Participant under the Plan will be credited to a Cash
Account maintained by the Company on behalf of the Participant. The Company will
credit payroll contributions to each Participant's Cash Account as soon as
practicable after the contributions are withheld from the Participant's
Earnings.

                  (f) No Interest on Cash Accounts. No interest will be credited
or paid on cash balances in Participant's Cash Accounts pending investment in
Stock.

         6. PURCHASES OF STOCK

                  (a) Purchase Rights. Enrollment in the Plan for any Offering
Period by a Participant will constitute a grant by the Company of a Purchase
Right to such Participant for such Offering Period. Each Purchase Right will be
subject to the following terms:

                           (i)      The purchase price of each share of Stock
                                    purchased for each Offering Period will
                                    equal 85% of the lesser of the Fair Market
                                    Value of a share of Stock on the first day
                                    of an Offering Period, or the Fair Market
                                    Value of a share of Stock on the last day of
                                    an Offering Period.

                           (ii)     Except as limited in (iii) below, the number
                                    of shares of Stock that may be purchased
                                    upon exercise of the Purchase Right for a
                                    Offering Period will equal the number of
                                    shares (including fractional shares) that
                                    can be purchased at the purchase price
                                    specified in Section 6(a)(i) with the
                                    aggregate amount credited to the
                                    Participant's Cash Account as of the last
                                    day of an Offering Period.

                           (iii)    The number of shares of Stock subject to a
                                    Participant's Purchase Right for any
                                    Offering Period will not exceed the number
                                    derived by dividing $6,250 by 100% of the
                                    Fair Market Value of one share of Stock on
                                    the first day of the Offering Period for the
                                    Offering Period.

                                                                               5
<PAGE>   6
                           (iv)     The Purchase Right will be automatically
                                    exercised on the last day of the Offering
                                    Period.

                           (v)      Payments by a Participant for Stock
                                    purchased under a Purchase Right will be
                                    made only through payroll deduction in
                                    accordance with Section 5(d) and (e).

                           (vi)     The Purchase Right will expire on the
                                    earlier of the last day of the Offering
                                    Period or the date on which the
                                    Participant's enrollment in the Plan
                                    terminates.

                  (b) Purchase of Stock. At or as promptly as practicable after
the last day of an Offering Period, amounts credited to each Participant's Cash
Account will be applied by the Company to purchase Stock, in accordance with the
terms of the Plan. Shares of Stock will be purchased from the Company or in the
open market, as the Board determines. The Company will aggregate the amounts in
all Cash Accounts when purchasing Stock, and shares purchased will be allocated
to each Participant's Stock Account in proportion to the cash amounts withdrawn
from such Participant's Cash Account. After completing purchases for each
Offering Period (which will be completed in not more than 15 calendar days after
the last day of an Offering Period), all shares of Stock so purchased for a
Participant will be credited to the Participant's Stock Account.

                  (c) Dividend Reinvestment; Other Distributions. Cash dividends
on any Stock credited to a Participant's Stock Account will be automatically
reinvested in additional shares of Stock; such amounts will not be available in
the form of cash to Participants. The Company will aggregate all purchases of
Stock in connection with dividend reinvestment for a given dividend payment
date. Purchases of Stock for purposes of dividend reinvestment will be made as
promptly as practicable (but not more than 15 calendar days) after a dividend
payment date. The purchases will be made directly from the Company at 100% of
the Fair Market Value of a share of Stock on the dividend payment date or on the
open market. Any shares of Stock distributed as a dividend or distribution in
respect of shares of Stock or in connection with a split of the Stock credited
to a Participant's Stock Account will be credited to such Account.

                  (d) Withdrawals and Transfers. Shares of Stock may be
withdrawn from a Participant's Stock Account, in which case one or more
certificates for whole shares may be issued in the name of, and delivered to,
the Participant, with such Participant receiving cash in lieu of fractional
shares based on the Fair Market Value of a share of Stock on the day preceding
the date of withdrawal. Alternatively, whole shares of Stock may be withdrawn
from a Participant's Stock Account by means of a transfer to a broker-dealer or
financial institution that maintains an account for the Participant, together
with the transfer of cash in lieu of fractional shares based on the Fair Market
Value of a share of Stock on the day preceding the date of withdrawal.
Participants may not designate any other person to receive shares of Stock
withdrawn or transferred under the Plan. A Participant seeking to withdraw or
transfer shares of Stock must give instructions to the Custodian in such manner
and form as may be prescribed by the Custodian, which instructions will be acted
upon as promptly as practicable. Withdrawals and transfers will be subject to
any fees imposed in accordance with Section 8(a).

                                                                               6
<PAGE>   7
                  (e) Excess Account Balances. If any amounts remain in a Cash
Account following the date on which the Company purchases Stock for an Offering
Period as a result of the limitation set forth in Section 6(a)(iii) or for any
other reason, such amounts will be returned to the Participant as promptly as
practicable.

         7. TERMINATION AND DISTRIBUTIONS.

                  (a) Termination of Enrollment. A Participant's enrollment in
the Plan will terminate upon (i) the beginning of any payroll period or Offering
Period that begins after he or she files a written notice of termination of
enrollment with the Company, provided that such Participant will continue to be
deemed to be enrolled with respect to any completed Offering Period for which
purchases have not been completed, (ii) such time as the Participant becomes
ineligible to participate under Section 5(a) of the Plan, or (iii) the
termination of the Participant's employment by the Company and its Subsidiaries.
An employee whose enrollment in the Plan terminates may again enroll in the Plan
as of any subsequent Offering Period that is at least 90 days after such
termination of enrollment if he or she satisfies the eligibility requirements of
Section 5(a) as of such Offering Period. A Participant's election to discontinue
payroll contributions will not constitute a termination of enrollment.

                  (b) Distribution. As soon as practicable after a Participant's
enrollment in the Plan terminates, amounts in the Participant's Cash Account
which resulted from payroll contributions will be repaid to the Participant. The
Custodian will continue to maintain the Participant's Stock Account for the
Participant until the earlier of such time as the Participant directs the sale
of all Stock in the Account, withdraws, or transfers all Stock in the Account,
or one year after the Participant ceases to be employed by the Company and its
Subsidiaries. If a Participant's termination of enrollment results from his or
her death, all amounts payable will be paid to his or her estate.

         8. GENERAL.

                  (a) Costs. Costs and expenses incurred in the administration
of the Plan and maintenance of Accounts will be paid by the Company, to the
extent provided in this Section 8(a). Any brokerage fees and commissions for the
purchase of Stock under the Plan (including Stock purchased upon reinvestment of
dividends and distributions) will be paid by the Company, but any brokerage fees
and commissions for the sale of Stock under the Plan by a Participant will be
borne by such Participant. The rate at which such fees and commissions will be
charged to Participants will be determined by the Custodian or any broker-dealer
used by the Custodian (including an affiliate of the Custodian), and
communicated from time to time to Participants. In addition, the Custodian may
impose or pass through a reasonable fee for the withdrawal of Stock in the form
of stock certificates (as permitted under Section 6(d)), and reasonable fees for
other services unrelated to the purchase of Stock under the Plan, to the extent
approved in writing by the Company and communicated to Participants.

                  (b) Statements to Participants. The Participant's statement
will reflect payroll contributions, purchases, sales, and withdrawals and
transfers of shares of Stock and other Plan transactions by appropriate
adjustments to the Participant's Accounts. The Custodian will, not

                                                                               7

less frequently than quarterly, provide or cause to be provided a written
statement to the Participant showing the transactions in his or her Stock
Account and the date thereof, the number of shares of Stock credited or sold,
the aggregate purchase price paid or sales price received, the purchase or sales
price per share, the brokerage fees and commissions paid (if any), the total
shares held for the Participant's Stock Account (computed to at least three
decimal places), and such other information as agreed to by the Custodian and
the Company.

                  (c) Compliance with Section 423. It is the intent of the
Company that this Plan comply in all respects with applicable requirements of
Section 423 of the Code and regulations thereunder. Accordingly, if any
provision of this Plan does not comply with such requirements, such provision
will be construed or deemed amended to the extent necessary to conform to such
requirements.

         9. GENERAL PROVISIONS.

                  (a) Compliance With Legal and Other Requirements. The Plan,
the granting and exercising of Purchase Rights hereunder, and the other
obligations of the Company and the Custodian under the Plan will be subject to
all applicable federal and state laws, rules, and regulations, and to such
approvals by any regulatory or governmental agency as may be required. The
Company may, in its discretion, postpone the issuance or delivery of Stock upon
exercise of Purchase Rights until completion of such registration or
qualification of such Stock or other required action under any federal or state
law, rule, or regulation, or the laws of any country in which employees of the
Company and a Subsidiary who are nonresident aliens and who are eligible to
participate reside, or other required action with respect to any automated
quotation system or stock exchange upon which the Stock or other Company
securities are designated or listed, or compliance with any other contractual
obligation of the Company, as the Company may consider appropriate. In addition,
the Company may require any Participant to make such representations and furnish
such information as it may consider appropriate in connection with the issuance
or delivery of Stock in compliance with applicable laws, rules, and regulations,
designation or listing requirements, or other contractual obligations.

                  (b) Limits on Encumbering Rights. No right or interest of a
Participant under the Plan, including any Purchase Right, may be pledged,
encumbered, or hypothecated to or in favor of any party, subject to any lien,
obligation, or liability of such Participant, or otherwise assigned,
transferred, or disposed of except pursuant to the laws of descent or
distribution, and any right of a Participant under the Plan will be exercisable
during the Participant's lifetime only by the Participant.

                  (c) No Right to Continued Employment. Neither the Plan nor any
action taken hereunder, including the grant of a Purchase Right, will be
construed as giving any employee the right to be retained in the employ of the
Company or any of its Subsidiaries, nor will it interfere in any way with the
right of the Company or any of its Subsidiaries to terminate any employee's
employment at any time.

                  (d) Taxes. The Company or any Subsidiary is authorized to
withhold from any payment to be made to a Participant, including any payroll and
other payments not related to the

                                                                               8
<PAGE>   9
Plan, amounts of withholding and other taxes due in connection with any
transaction under the Plan, and a Participant's enrollment in the Plan will be
deemed to constitute his or her consent to such withholding. In addition,
Participants may be required to advise the Company of sales and other
dispositions of Stock acquired under the plan in order to permit the Company to
comply with tax laws and to claim any tax deductions to which the Company may be
entitled with respect to the Plan. This provision and other Plan provisions do
not set forth an explanation of the tax consequences to Participants under the
Plan. A brief summary of the tax consequences will be included in disclosure
documents to be separately furnished to Participants.

                  (e) Changes to the Plan. The Board may amend, alter, suspend,
discontinue, or terminate the Plan without the consent of shareholders or
Participants, except that any such action will be subject to the approval of the
Company's shareholders within one year after such Board action if such
shareholder approval is required by any federal or state law or regulation or
the rules of any automated quotation system or stock exchange on which the Stock
may then be quoted or listed, or if such shareholder approval is necessary in
order for the Plan to continue to meet the requirements of Section 423 of the
Code, and the Board may otherwise, in its discretion, determine to submit other
such actions to shareholders for approval. However, without the consent of an
affected Participant, no amendment, alteration, suspension, discontinuation, or
termination of the Plan may materially and adversely affect the rights of such
Participant with respect to outstanding Purchase Rights relating to any Offering
Period that has been completed prior to such Board action. The foregoing
notwithstanding, upon termination of the Plan the Board may (i) elect to
terminate all outstanding Purchase Rights at such time as the Board may
designate, and all amounts contributed to the Plan which remain in a
Participant's Cash Account will be returned to the Participant (without
interest) as promptly as practicable, or (ii) shorten the Offering Period to
such period determined by the Board and use amounts credited to a Participant
Cash Account to purchase Stock.

                  (f) No Rights to Participate; No Shareholder Rights. No
Participant or employee will have any claim to participate in the Plan with
respect to Offering Periods that have not commenced, and the Company will have
no obligation to continue the Plan. No Purchase Right will confer on any
Participant any of the rights of a shareholder of the Company unless and until
Stock is duly issued or transferred and delivered to the Participant (or
credited to the Participant's Stock Account).

                  (g) Fractional Shares. Unless otherwise determined by the
Board, purchases of Stock under the Plan executed by the Custodian may result in
the crediting of fractional shares of Stock to the Participant's Stock Account.
Such fractional shares will be computed to at least three decimal places.
Fractional shares will not, however, be issued by the Company, and certificates
representing fractional shares will not be delivered to Participants under any
circumstances.

                  (h) Plan Year. The Plan will operate on a plan year that
begins on January 1 and ends December 31 in each year.

                  (i) Governing Law. The validity, construction, and effect of
the Plan and any rules and regulations relating to the Plan will be determined
in accordance with the laws of the

                                       9
<PAGE>   10
State of Arizona, without giving effect to principles of conflicts of laws, and
applicable federal law.

                  (j) Effective Date. The Plan will become effective on the IPO
Date, subject to the Plan being approved by shareholders of the Company, at a
meeting by a vote sufficient to meet the requirements of Section 423(b)(2) of
the Code. If the Plan is not approved in accordance with Section 423(b)(2) of
the Code, each Participant's Purchase Right shall be void and amounts credited
to the Participant's Cash Account shall be promptly returned to the Participant.

                                                                              10<PAGE>   1

         3.1 GENERAL. Each Director shall be eligible to participate in the
Plan.

         3.2 APPLICATION TO PARTICIPATE. Each Director may become a Participant
by completing and signing an enrollment form provided by, or acceptable to, the
Plan Administrator and delivering the form to the Plan Administrator. The
Director must designate on the form the amount of his Deferral Contributions and

participate in the Plan, the Director has 30 days to notify the Plan
Administrator whether he will participate in the Plan. If the Director timely
notifies the Plan Administrator of his intent to participate in the Plan, the

his Deferral Contributions, the new amount or rate of Deferral Contributions

Participation Agreement is filed and only with respect to Fees payable for
services as a Director thereafter. If the new Participation Agreement changes
the method and/or timing of the commencement of distributions, the new election
will only be honored if at least one full calendar year elapses between (a) the
date as of which such distribution would otherwise have commenced and (b) the
date as of which such distribution will commence under such election.

                                   SECTION 4
                                 CONTRIBUTIONS

         4.1 PARTICIPANT CONTRIBUTIONS.

             (a) DEFERRAL OF FEES. For any Plan Year, a Participant may elect to
defer a portion of the Fees otherwise payable to him. Any such deferrals shall
be in whole percentages or a specific dollar amount of the Participant's Fees,
as specified in the Participant's Participation Agreement. Contributions of
amounts deferred shall be made by the Company directly to the Trust.

             (b) LIMITATIONS ON DEFERRALS. Unless otherwise provided by the Plan
Administrator, a Participant is permitted to defer up to 100% of the
Participant's Fees under this Plan.

         4.2 CHANGE IN PARTICIPANT CONTRIBUTIONS. A Participant may change the
amount or percentage of Deferral Contributions as of the first day of any Plan
Year by filing a new Participation Agreement or any other form permitted by the
Plan Administrator. The change shall become effective as provided in Section
3.4.

                                   SECTION 5
                                  WITHDRAWALS

         5.1 HARDSHIP. In the event of an unforeseeable financial emergency, a
Participant may make a written request to the Plan Administrator for a hardship
withdrawal from his Account. For purposes of this Plan, an "unforeseeable
financial emergency" is defined as a severe financial hardship to the
Participant resulting from a sudden and unexpected illness or accident of the
Participant or a dependent (as such term is defined in Section 152(a) of the
Code) of the Participant, loss of the Participant's property due to casualty, or
other similar extraordinary and unforeseeable circumstances arising as a result
of events beyond the control of the Participant. The granting of a Participant's
request for a hardship withdrawal shall be left to the

                                                                               4
<PAGE>   7
absolute discretion of the Plan Administrator and the Plan Administrator may
deny such request even if an unforeseeable financial emergency clearly exists. A
request for a hardship withdrawal must be made in writing at least 30 days in
advance, on a form provided by the Plan Administrator, and must be expressed as
a specific dollar amount. The amount of a hardship withdrawal may not exceed the
lesser of the amount required to meet the Participant's unforeseeable financial
emergency or the entire balance of the Participant's Account. A hardship
withdrawal will not be permitted to the extent that the hardship is or may be
relieved through reimbursement or compensation by insurance or otherwise,
liquidation of the Participant's assets to the extent that such liquidation
would not itself cause a severe financial hardship, or by the cessation of
Deferral Contributions.

         5.2 ACCELERATION OF BENEFITS.

             (a) GENERAL. A Participant may elect to receive an accelerated
withdrawal by filing an election with the Plan Administrator on such forms as
may be prescribed from time to time by the Plan Administrator. If a Participant
makes such an election, the Participant shall receive a single lump sum payment
equal to the Participant's "available Account balance." For this purpose, the
Participant's "available Account balance" equals the lesser of (a) the value of
the Participant's Account as of the Valuation Date immediately prior to
termination of service (plus any Deferral Contributions made between such
Valuation Date and the date of termination of service), or (b) the sum of the
Participant's Deferral Contributions made under the Plan. The accelerated
withdrawal shall be paid as soon as reasonably practicable following the filing
of the election by the Participant.

             (b) FORFEITURE. If the Participant elects to receive an accelerated
withdrawal, the Participant shall forfeit any amounts ever credited as earnings
or income on Deferral Contributions to his Account. The Deferral Contributions
made by the Participant during the Plan Year in which the accelerated withdrawal
request is made shall not be forfeited.

             (c) SUSPENSION OF PARTICIPATION. If a Participant elects to receive
an accelerated withdrawal, the Participant's right to participate in the Plan
shall be suspended for all future periods.

         5.3 CREDITING OF WITHDRAWALS. Withdrawals and other distributions shall
be charged pro rata to the Investment Funds in which the Account of the
Participant is invested, pursuant to his designation under Section 6.3 hereof.

                                   SECTION 6
                      CREDITING OF CONTRIBUTIONS AND INCOME

         6.1 TRANSFER TO TRUSTEE. All Deferral Contributions shall be
transmitted to the Trustee by the Company as soon as reasonably practicable and
shall be credited to the Accounts of the Participants immediately upon receipt.
All payments from an Account between Valuation Dates shall be charged against
the Account as of the preceding Valuation Date. The Accounts are bookkeeping
accounts only and the Plan Administrator is not in any way obligated to
segregate assets for the benefit of any Participant.

                                                                               5
<PAGE>   8
         6.2 CREDITING TO ACCOUNTS. Except as otherwise provided in the Plan and
Trust, as of each Valuation Date the Plan Administrator shall adjust each
Participant's Account with the positive or negative rate of return on the
Investment Funds selected by the Participant pursuant to Section 6.3(b). The
rate of return will be determined by the Plan Administrator pursuant to Section
6.3(c) and will be credited or charged against the "adjusted balance" of the
Account, which will be the balance of the Account as of the preceding Valuation
Date less all withdrawals, distributions and other amounts chargeable against
the Account pursuant to any other provisions of this Plan since the prior
Valuation Date. In the exercise of its discretion, the Plan Administrator also
may direct that a portion of the Deferral Contributions made since the prior
Valuation Date be considered in calculating the adjusted balance of the Account.

         6.3 INVESTMENT DIRECTION.

             (a) INVESTMENT FUNDS. The Plan Administrator shall establish one or
more Investment Funds in which each Participant shall invest amounts credited to
his Account. The Investment Funds shall include such funds as may be selected
from time to time by the Plan Administrator. The Investment Funds may be changed
from time to time by the Plan Administrator.

             (b) PARTICIPANT DIRECTIONS.

                 (1) GENERAL. Upon becoming a Participant of the Plan, each
Participant may, subject to the approval by the Trustee, direct that all of the
amounts attributable to his Account be invested in a single investment fund or
may direct fractional (percentage) increments of his Account to be invested in
such fund or funds as he shall desire, on such forms and in accordance with such
procedures, if any, as may be established by the Plan Administrator. Subject to
the Trustee's approval, such designation may be changed no more than twice per
Plan Year (or such other greater amount as permitted by the Plan Administrator
in its sole discretion), with respect to future contributions and transfers
among Investment Funds, by filing an election with the Plan Administrator, on a
form prescribed by the Plan Administrator. The designation will continue until
changed by the timely submission of a new form.

                 (2) DEFAULT SELECTION. In the absence of any designation, a
Participant will be deemed to have directed the investment of his Accounts in
such Investment Funds as the Trustee, in its sole and absolute discretion, shall
determine. In no event may a Participant designate the investment of his Account
in stock or other securities of the Company or any Affiliate.

                 (3) IMPACT OF ELECTION. The Participant's selection of
Investment Funds shall serve only as a measurement of the value of the Accounts
of the Participant pursuant to Section 6.2 and Section 6.3(c) and the Plan
Administrator and the Trustee are not required to invest a Participant's
Accounts in accordance with the Participant's selections.

             (c) RATE OF RETURN. As soon as possible after each Valuation Date,
the Plan Administrator shall determine the rate of return, positive or negative,
experienced on each of the Investment Funds. The rate of return determined by
the Plan Administrator in good faith

                                                                               6
<PAGE>   9
and in its discretion pursuant to this Section shall be binding and conclusive
on the Participant, the Participant's Beneficiary and all parties claiming
through them.

             (d) CHARGES. The Plan Administrator may charge each Participant's
Account for the reasonable expenses of carrying out investment instructions
directly related to such Account.

                                   SECTION 7
                                    VESTING

         7.1 VESTING. Subject to Sections 5.2 and 8.1, Participant's shall have
a fully vested, non-forfeitable interest in his Account at all times.

                                   SECTION 8
                            DISTRIBUTION OF BENEFITS

         8.1 TERMINATION OF SERVICE. A Participant who terminates service as a
Director of the Company for any reason other than death or Disability is
entitled to a distribution of amounts credited to his Account at the time and in
the manner provided in Section 8.6. Notwithstanding the above, if the
Participant's service is terminated for Cause, the Participant will forfeit any
earnings or income ever credited to the Participant's Account and shall only be
entitled to a distribution equal to the lesser of (a) the value of the
Participant's Account as of the Valuation Date immediately prior to termination
of service (plus any Deferral Contributions made between such Valuation Date and
the date of termination of service), or (b) the sum of the Participant's
Deferral Contributions made under the Plan.

         8.2 DISABILITY RETIREMENT. A Participant who terminates service as a
Director of the Company due to Disability is entitled to a distribution of
amounts credited to his Account as provided in Section 8.6. Subject to Section
8.6, the payments may commence as of his date of termination of service due to
Disability.

         8.3 DEATH.

             (a) BENEFIT. If a Participant (which term for purposes of this
Section includes a former Participant) dies before the day on which his benefit
payments commence, the Participant's Beneficiary is entitled to a distribution
of amounts credited to the Participant's Account at the time and in the manner
provided in Section 8.6.

             (b) DEATH AFTER COMMENCEMENT OF BENEFITS. If a former Participant
dies after the day on which his benefit payments commence, but prior to the
complete distribution of all amounts to which such Participant is entitled, the
Participant's Beneficiary is entitled to receive any remaining amounts to which
the Participant would have been entitled had the Participant survived at the
time and in the manner provided in Section 8.6. The Plan Administrator may
require and rely upon such proofs of death and the right of any Beneficiary to
receive benefits under this Section 8.3 as the Plan Administrator may reasonably
determine, and its determination of death and the right of such Beneficiary to
receive payment is binding and conclusive upon all persons.

                                                                               7
<PAGE>   10
         8.4 PLANNED DISTRIBUTIONS. A Participant may, in his Participation
Agreement, make an irrevocable election to receive a distribution of benefits
under this Plan with respect to all or any portion of Deferral Contributions
made under this Plan at a specific time prior to termination of service, death,
or Disability, provided, that such planned distribution may not be distributed
earlier than four years after the date to which the Deferral Contribution
relates is made and may not be paid out over a period of more than five years.

         8.5 CHANGE OF CONTROL. In the event of a Change of Control, the
Participant shall be entitled to a lump sum payment of the entire amount
allocated to the Participant's Account as of the date of such Change of Control.
Such payment shall be made within 30 days of the effective date of the event
constituting the Change of Control.

         8.6 TIME AND METHOD OF DISTRIBUTION OF BENEFITS.

             (a) TERMINATION. Payment to a Participant who is entitled to
benefits under Section 8.1 will commence within a reasonable time following the
Valuation Date next following the Participant's termination of service.

             (b) DISABILITY. Payment to a Participant who is entitled to
benefits under Section 8.2 will commence as soon as possible after the Valuation
Date next following the Participant's termination of service due to a
Disability.

             (c) DEATH AFTER COMMENCEMENT OF PAYMENTS. If a Participant dies
after the day on which his benefit payments commence but before the complete
distribution to such Participant of the benefits payable to him under the Plan,
any remaining benefits will be distributed to the Participant's Beneficiary in
either a single lump sum or over the period of years selected by the
Participant, provided that if the Participant's Beneficiary is not the
Participant's spouse, the distribution will be made in a lump sum. Payments to
the Beneficiaries entitled to payments pursuant to Section 8.3 will commence as
soon as possible following the death of the Participant.

             (d) DEATH BEFORE COMMENCEMENT OF BENEFITS. If a Participant dies
before the day on which his benefit payments commence, payments to the
Participant's Beneficiary will commence as soon as possible following the
Participant's death.

             (e) FORM OF PAYMENT. Any distribution paid from the Plan to a
Participant or Beneficiary from a Participant's Account will be paid in cash.
Except as otherwise provided in Sections 8.4 and 8.5, such distribution will be
paid in either a lump sum payment or in installments over a period not to exceed
15 years; provided that if the value of the Participant's Account at the time of
distribution is less than $100,000, the Plan Administrator reserves the right to
make such distribution in a lump sum. Any remaining balance in the Participant's
Account will be credited with investment experience in the Trust Fund.

         8.7 DESIGNATION OF BENEFICIARY. Each Participant has the right to
designate, on forms supplied by, or acceptable to, and delivered to the Plan
Administrator, a Beneficiary or Beneficiaries to receive his benefits in the
event of his death. For each Participant who is married, his Beneficiary will be
deemed to be his spouse, unless the Participant's spouse consents to the
Participant's Beneficiary designation to the contrary. Such consent must be in

                                                                               8
<PAGE>   11
writing, must acknowledge the effect of the Beneficiary designation and the
spouse's consent thereto. Subject to the foregoing, each Participant may change
his Beneficiary designation from time to time in the manner described above and
the change will be effective upon receipt by the Plan Administrator, whether or
not the Participant is living at the time the notice is received. There is no
liability on the part of the Plan Administrator with respect to any payment
authorized by the Plan Administrator in accordance with the most recent valid
Beneficiary designation of the Participant in the Plan Administrator's
possession before receipt of a more recent and valid Beneficiary designation. If
no designated Beneficiary is living when benefits become payable, or if there is
no designated Beneficiary, the Beneficiary will be the Participant's spouse; or
if no spouse is then living, such Participant's issue, including any legally
adopted child or children, in equal shares by right of representation; or if no
such designated Beneficiary and no such spouse or issue, including any legally
adopted child or children, is living upon the death of a Participant, or if all
such persons die prior to the full distribution of such Participant's benefits,
then the Beneficiary shall be the estate of the Participant.

         8.8 PAYMENTS TO DISABLED. If a person entitled to any payment is under
a legal disability, or in the sole judgment of the Plan Administrator is
otherwise unable to apply such payment to his own interest and advantage, the
Plan Administrator in the exercise of its discretion may make any such payment
in any one or more of the following ways: (a) directly to such person, (b) to
his legal guardian or conservator, or (c) to his spouse or to any person charged
with the legal duty of his support, to be expended for his benefit. The decision
of the Plan Administrator will in each case be final and binding upon all
persons in interest.

         8.9 UNDERPAYMENT OR OVERPAYMENT OF BENEFITS. In the event that, through
misstatement or computation error, benefits are underpaid or overpaid, there is
no liability for any more than the correct benefit sums under the Plan.
Overpayments may be deducted from future payments under the Plan, and
underpayments may be added to future payments under the Plan. In lieu of
receiving reduced benefits under the Plan, a Participant or beneficiary may
elect to make a lump sum repayment of any overpayment.

                                   SECTION 9

                                   SECTION 10
                             CLAIMS REVIEW PROCEDURE

         10.1 CLAIMS.

             (a) FILING OF CLAIM. A Participant or Beneficiary entitled to
benefits need not file a written claim to receive benefits. If a Participant,
Beneficiary or any other person is dissatisfied with the determination of his
benefits, eligibility, participation or any other right or interest under this
Plan, such person may file a written statement setting forth the basis of the
claim with the Plan Administrator in a manner prescribed by the Plan
Administrator. In connection with the determination of a claim, or in connection
with review of a denied claim, the claimant may examine this Plan and any other
pertinent documents generally available to Participants relating to the claim
and may submit comments in writing.

             (b) NOTICE OF DECISION. A written notice of the disposition of any
such claim shall be furnished to the claimant within 30 days after the claim is
filed with the Plan Administrator, provided that the Plan Administrator may have
an additional period to decide the claim if it advises the claimant in writing
of the need for an extension and the date on which it expects to decide the
claim. The notice of disposition of a claim shall refer, if appropriate, to
pertinent provisions of this Plan, shall set forth in writing the reasons for
denial of the claim if the claim is denied (including references to any
pertinent provisions of this Plan), and where appropriate shall explain how the
claimant can perfect the claim.

         10.2 APPEALS.

             (a) If the claimant should appeal to the Plan Administrator, he, or
his duly authorized representative, may submit, in writing, whatever issues and
comments he, or his duly authorized representative, feels are pertinent. The
Plan Administrator shall re-examine all facts related to the appeal and make a
final determination as to whether the denial of benefits is justified under the
circumstances. The Plan Administrator shall advise the claimant in writing of
its decision on his appeal, the specific reasons for the decision, and the
specific Plan provisions on which the decision is based. The notice of the
decision shall be given within 60 days of the claimant's written request for
review, unless special circumstances (such as a hearing) would make the
rendering of a decision within the 60 day period infeasible, but in no event
shall the Plan Administrator render a decision regarding the denial of a claim
for benefits later than 120

                                                                              11
<PAGE>   14
days after its receipt of a request for review. If an extension of time for
review is required because of special circumstances, written notice of the
extension shall be furnished to the claimant prior to the date the extension
period commences.

             (b) If, upon appeal, the Plan Administrator shall grant the relief
requested by the claimant, then, in addition, the Plan Administrator shall award
to the claimant reasonable fees and expenses of counsel, or any other duly
authorized representative of claimant, which shall be paid by the Company. The
determination as to whether such fees and expenses are reasonable shall be made
by the Company in its sole and absolute discretion and such determination shall
be binding and conclusive on all parties.

         10.3 NOTICE OF DENIALS. The Plan Administrator's notice of denial of
benefits shall identify the address to which the claimant may forward his
appeal.

                                   SECTION 11
                       LIMITATION OF RIGHTS, CONSTRUCTION

         11.1 LIMITATION OF RIGHTS. Neither this Plan, the Trust nor membership
in the Plan shall give any person any right except to the extent that the right
is specifically fixed under the terms of the Plan. The establishment of the Plan
shall not be construed to give any individual a right to be continued in the
service of the Company or as interfering with the right of the Company to
terminate the service of any individual at any time.

         11.2 CONSTRUCTION. The masculine gender, where appearing in the Plan,
shall include the feminine gender (and vice versa), and the singular shall
include the plural, unless the context clearly indicates to the contrary.
Headings and subheadings are for the purpose of reference only and are not to be
considered in the construction of this Plan. If any provision of this Plan is
determined to be for any reason invalid or unenforceable, the remaining
provisions shall continue in full force and effect. All of the provisions of
this Plan shall be construed and enforced in accordance with the laws of the
State of Arizona.

                                   SECTION 12
                 LIMITATION ON ASSIGNMENT; PAYMENTS TO LEGALLY
                             INCOMPETENT DISTRIBUTEE

         12.1 ANTI-ALIENATION CLAUSE. No benefit which shall be payable under
the Plan to any person shall be subject in any manner to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any
attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber,
charge or otherwise dispose of the same shall be void. No benefit shall in any
manner be subject to the debts, contracts, liabilities, engagements or torts of
any person, nor shall it be subject to attachment or legal process for or
against any person, except to the extent as may be required by law.

         12.2 PERMITTED ARRANGEMENTS. Section 12.1 shall not preclude
arrangements for the withholding of taxes from benefit payments, arrangements
for the recovery of benefit overpayments, arrangements for the transfer of
benefit rights to another plan, or arrangements for direct deposit of benefit
payments to an account in a bank, savings and loan association or credit union
(provided that such arrangement is not part of an arrangement constituting an
assignment

                                                                              12
<PAGE>   15
or alienation). Additionally, Section 12.1 shall not preclude arrangements for
the distribution of the benefits of a Participant or Beneficiary pursuant to the
terms and provisions of a "domestic relations order" in accordance with such
procedures as may be established from time to time by the Plan Administrator.

         12.3 PAYMENT TO MINOR OR INCOMPETENT. Whenever any benefit which shall
be payable under the Plan is to be paid to or for the benefit of any person who
is then a minor or determined by the Plan Administrator to be incompetent by
qualified medical advice, the Plan Administrator need not require the
appointment of a guardian or custodian, but shall be authorized to cause the
same to be paid over to the person having custody of the minor or incompetent,
or to cause the same to be paid to the minor or incompetent without the
intervention of a guardian or custodian, or to cause the same to be paid to a
legal guardian or custodian of the minor or incompetent if one has been
appointed or to cause the same to be used for the benefit of the minor or
incompetent.

                                   SECTION 13
                       AMENDMENT, MERGER, AND TERMINATION

         13.1 AMENDMENT. The Company shall have the right at any time, by an
instrument in writing duly executed, acknowledged and delivered to the Plan
Administrator, to modify, alter or amend this Plan, in whole or in part,
prospectively or retroactively; provided, however, that the duties and
liabilities of the Plan Administrator and the Trustee hereunder shall not be
substantially increased without its written consent; and provided further that
the amendment shall not reduce any Participant's interest in the Plan,
calculated as of the date on which the amendment is adopted.

         13.2 MERGER OR CONSOLIDATION OF COMPANY. The Plan shall not be
automatically terminated by the Company's acquisition by or merger into any
other employer, but the Plan shall be continued after such acquisition or merger
if the successor employer elects and agrees to continue the Plan. All rights to
amend, modify, suspend, or terminate the Plan shall be transferred to the
successor employer, effective as of the date of the merger.

         13.3 TERMINATION OF PLAN OR DISCONTINUANCE OF CONTRIBUTIONS. It is the
expectation of the Company that this Plan and the payment of contributions
hereunder will be continued indefinitely. However, continuance of the Plan is
not assumed as a contractual obligation of the Company, and the right is
reserved at any time to terminate this Plan or to reduce, temporarily suspend or
discontinue contributions hereunder.

         13.4 LIMITATION OF COMPANY'S LIABILITY. The adoption of this Plan is
strictly a voluntary undertaking on the part of the Company and shall not be
deemed to constitute a contract between the Company and any Participant or to be
consideration for, an inducement to, or a condition of the continued service of
the Participant or any other individual. A Participant or Beneficiary shall not
have any right to retirement or other benefits except to the extent provided
herein.

                                                                              13

                               GENERAL PROVISIONS

         14.1 STATUS OF PARTICIPANTS AS UNSECURED CREDITORS. All benefits under
the Plan shall be the unsecured obligations of the Company as applicable, and,
except for those assets which will be placed in the Trust established in
connection with this Plan, no assets will be placed in trust or otherwise
segregated from the general assets of the Company or each Company, as
applicable, for the payment of obligations hereunder. To the extent that any
person acquires a right to receive payments hereunder, such right shall be no
greater than the right of any unsecured general creditor of the Company.

         14.2 UNIFORM ADMINISTRATION. Whenever in the administration of the Plan
any action is required by the Plan Administrator, such action shall be uniform
in nature as applied to all persons similarly situated.

         14.3 HEIRS AND SUCCESSORS. All of the provisions of this Plan shall be
binding upon all persons who shall be entitled to any benefits hereunder, and
their heirs and legal representatives.

         To signify its adoption of this Plan document, the Company has caused
this Plan document to be executed by a duly authorized officer of the Company on
this 8th day of March, 2000.
