Section 4.     Eligibility

     Awards may only be granted to officers and key employees of or

making Awards, the Committee may consider such factors as the Employee's
functions and responsibilities and the Employee's past, present and future
contributions to the Company's profitability and growth.

     Neither the members of the Committee nor any member of the Board who is

and for any reason.

Section 5.     Maximum Amount Available for Awards and Maximum Award

     The aggregate number of shares of Common Stock that may be issued under
Awards pursuant to this Plan on an annual basis shall not exceed one percent
(1%) of the issued and outstanding shares of Common Stock as of the first
day of each calendar year for which the Plan is in effect.  Any shares
available in any year using this formula that are not granted under this
Plan or other plans in which stock is awarded to Employees would be
available for use in subsequent years.  Shares of Common Stock may be made
available from the authorized but unissued shares of the Company or from
shares reacquired by the Company, including shares purchased in the open
market.  In the event that an Option or Right expires or is terminated
unexercised as to any shares of Common Stock covered thereby, or any Award
in respect of shares is forfeited for any reason under the Plan, such
shares, to the extent not precluded by applicable law or regulation, shall
be again available for Awards pursuant to the Plan.

     In the event that the Committee shall determine that any stock
dividend, extraordinary cash dividend, recapitalization, reorganization,
merger, consolidation, split-up, spin-off, combination, exchange of shares,
warrants or rights offering to purchase Common Stock at a price
substantially below fair market value or other similar corporate event
affects the Common Stock such that an adjustment is required in order to
preserve the benefits or potential benefits intended to be made available
under this Plan, then the Committee, in its sole discretion, may take
action.  The Committee may adjust any or all of the number and kind of
shares that thereafter may be awarded or optioned and sold or made the
subject of Rights under the Plan, the number and kind of shares subject to
outstanding Options and other Awards, and the grant, exercise or conversion
price with respect to any of the foregoing and/or, if deemed appropriate,
make provision for a cash payment to a Participant or a person who has an
outstanding Option or other Award.

     There is a maximum of 200,000 shares that can be the subject of Awards
granted to any single Participant in any given fiscal year.

Section 6.     Stock Options

     (a)  Grant.  Subject to the provisions of the Plan, the Committee shall
have sole and complete authority to determine the Employees to whom Options
shall be granted, the number of shares to be covered by each Option, the
option price therefor and the conditions and limitations, applicable to the
exercise of the Option.  The Committee shall have the authority to grant
Incentive Stock Options, Nonqualified Stock Options, or both types of
Options.  In the case of Incentive Stock Options, the terms and conditions
of such grants shall be subject to and comply with such rules as may be
prescribed by Section 422 of the Code and any implementing regulations.

     (b)  Option Price.  The Committee shall establish the option price at
the time each Option is granted, which price shall not be less than 100
percent of the Fair Market Value of the Common Stock on the date of grant.

     (c)  Exercise.  Each Option shall be exercisable at such times and
subject to such terms and conditions as the Committee, in its sole
discretion, may specify in the applicable Award or thereafter; provided,
however, that in no event may any Option granted hereunder be exercisable
earlier than six months after the date of such grant or after the expiration
of ten years from the date of such grant.  The Committee may impose such
conditions with respect to the exercise of Options, including without
limitation, any conditions relating to the application of federal or state
securities laws, as it may deem necessary or advisable.

     No shares shall be delivered pursuant to any exercise of an Option
until payment in full of the option price is received by the Company.  Such
payment may be made in cash, or its equivalent, or, if and to the extent
permitted by the Committee, by exchanging shares of Common Stock owned by
the optionee (which are not the subject of any pledge or other security
interest), or by a combination of the foregoing, provided that the combined
value of all cash and cash equivalents and the Fair Market Value of any such
Common Stock so tendered to the Company, valued as of the date of such
tender, is at least equal to such option price.

     (d)  Transferability.  Participants are allowed to transfer vested
Nonqualified Stock Options to Family Members or family trusts, provided that
such options were granted as of and after February 10, 1998 and provided
that such transfers are made and transferred Options are exercised in
accordance with procedural rules adopted by the Committee.

Section 7.     Stock Appreciation Rights

     (a)  The Committee may, with sole and complete authority, grant Rights
in tandem with an Option.  Rights shall not be exercisable earlier than six
months after grant, shall not be exercisable after the expiration of ten
years from the date of grant and shall have an exercise price of not less
than 100 percent of the Fair Market Value of the Common Stock on the date of
grant.

     (b)  A Right shall entitle the Participant to receive from the Company
an amount equal to the excess of the Fair Market Value of a share of Common
Stock on the exercise of the Right over the grant price thereof.  The
Committee shall determine whether such Right shall be settled in cash,
shares of Common Stock or a combination of cash and shares of Common Stock.

Section 8.     Performance Shares

     (a)  The Committee shall have sole and complete authority to determine
the Employees who shall receive Performance Shares and the number of such
shares for each Performance Period and to determine the duration of each
Performance Period and the value of each Performance Share.  There may be
more than one Performance Period in existence at any one time, and the
duration of Performance Periods may differ from each other.

     (b)  Once the Committee decides to use Performance Shares, it shall
establish Performance Goals for each Period on the basis of criteria
selected by it.  During any Period, the Committee may adjust the Performance
Goals for such Period as it deems equitable in recognition of unusual or
non-recurring events affecting the Company, changes in applicable tax laws
or accounting principles, or such other factors as the Committee may determine.

     (c)  As soon as practicable after the end of a Performance Period, the
Committee shall determine the number of Performance Shares that have been
earned on the basis of performance in relation to the established
Performance Goals.  Payment Values of earned Performance Shares shall be
distributed to the Participant or as soon as practicable after the
expiration of the Performance Period and the Committee's determination.  The
Committee shall determine whether Payment Values are to be distributed in
the form of cash and/or shares of Common Stock.

Section 9.     Restricted Stock and Restricted Stock Units

     (a)  Subject to the provisions of the Plan, the Committee shall have
sole and complete authority to determine the Employees to whom shares of
Restricted Stock and Restricted Stock Units shall be granted, the number of
shares of Restricted Stock and the number of Restricted Stock Units to be
granted to each Participant, the duration of the Restricted Period during
which and the conditions under which the Restricted Stock and Restricted
Stock Units may be forfeited to the Company, and the other terms and
conditions of such Awards.

     (b)  Shares of Restricted Stock and Restricted Stock Units may not be
sold, assigned, transferred, pledged or otherwise encumbered, except as
herein provided, during the Restricted Period.  At the expiration of the
Restricted Period, the Company shall deliver such certificates to the
Participant or the Participant's legal representative.  Payment for
Restricted Stock Units shall be made to the Company in cash and/or shares of
Common Stock, as determined at the sole discretion of the Committee.

Section 10.    Other Stock Based Awards

     (a)  In addition to granting Options, Rights, Performance Shares,
Restricted Stock, Restricted Stock Units, the Committee shall have authority
to grant Stock Unit Awards to Participants that can be in the form of Common
Stock or units, the value of which is based, in whole or in part, on the
value of Common Stock.  Subject to the provisions of the Plan, Stock Unit
Awards shall be subject to such terms, restrictions, conditions, vesting
requirements and payment rules as the Committee may determine in its sole
and complete discretion at the time of grant.

     (b)  Any shares of Common Stock that are part of a Stock Unit Award may
not be assigned, sold, transferred, pledged or otherwise encumbered prior to
the date on which the shares are issued or, if later, the date provided by
the Committee at the time of grant of the Stock Unit Award.

     Stock Unit Awards may provide for the payment of cash consideration by
the person to whom such Award is granted or provide that the Award, and any
Common Stock to be issued in connection therewith, if applicable, shall be
delivered without the payment of cash consideration, provided that for any
Common Stock to be purchased in connection with a Stock Unit Award the
purchase price shall be at least 50 percent of the Fair Market Value of such
Common Stock on the date such Award is granted.

     Stock Unit Awards may relate in whole or in part to certain performance
criteria established by the Committee at the time of grant.  Stock Unit
Awards may provide for deferred payment schedules and/or vesting over a
specified period of employment.  In such circumstances as the Committee may
deem advisable, the Committee may waive or otherwise remove, in whole or in
part, any restriction or limitation to which a Stock Unit Award was made
subject at the time of grant.

     (c)  In the sole and complete discretion of the Committee, an Award,
whether made as a Stock Unit Award under this Section 10 or as an Award
granted pursuant to Sections 6 through 9, may provide the Participant with
dividends or dividend equivalents (payable on a current or deferred basis)
and cash payments in lieu of or in addition to an Award.

Section 11.    Termination of Employment

     The following provisions define a Participant's status in the event of
termination of employment:

     (a)  Options and Rights.  If a Participant shall cease to be employed
by the Company or an Affiliate either directly or in a consulting role, any
Option and any Right granted to him under the Plan shall terminate in
accordance with the following rules:

          (1)  A Participant who terminates employment for any reason other
than Approved Termination, Disability, death, or Reduction in Force shall
lose the right to exercise any Options or Rights as of Termination of
Employment.  Any Options transferred to a Family Member or family trust
shall also be terminated as of the Participant's Termination of Employment
for any reason other than Approved Termination, Disability, death or
Reduction in Force.

          (2)  A Participant who terminates employment as a result of an
Approved Termination shall have a period of time specified in the individual
agreements by which Options are granted to exercise such Options or Rights.

          (3)  A Participant who is Disabled shall have 12 months after
Termination of Employment in which to exercise an Option or Right.

          (4)  A Participant whose employment is terminated as a result of a
Reduction in Force shall have 30 days from the date on which he is notified
of his termination to exercise any Options or Rights that were vested as of
the date of notification.

          (5)  Upon the death of a Participant during employment, the
Participant's Designated Beneficiary shall have 12 months from the date of
death to exercise the Participant's Option or Right.  Upon the death of a
Participant after an Approved Termination but within the period specified by
the Committee to exercise Options or Rights after the Participant's Approved
Termination, the Participant's Designated Beneficiary shall have the period
specified by the Committee to exercise the Option or Right.

          (6)  The foregoing notwithstanding, a Participant or the
Participant's Designated Beneficiary shall not be permitted to exercise an
Option or Right after the expiration date and a Participant shall forfeit
any Options or Rights upon a determination made by the Board that the
Participant has accepted employment or provided consulting services to a
direct competitor of the Company.

     (b)  Restricted Stock.  If a Participant terminates employment before
the end of the Restricted Period for a reason other than death, Approved
Termination, Disability, Change of Control, or Reduction in Force, the
Participant shall forfeit all shares of Restricted Stock as of Termination
of Employment.  If a Participant terminates employment as a result of death,
Approved Termination, Change of Control, or Reduction in Force, the
Committee, in its sole discretion, shall determine what portion, if any, of
the Restricted Stock shall be freed from restrictions.

     (c)  Performance Shares and Other Awards.  If a Participant ceases to
be an Employee before the end of any Performance Period as a result of
death, Approved Termination, Disability, or Reduction in Force, the
Committee may authorize the payment to such Participant or his Designated
Beneficiary of a pro rata portion of the amount that would have been paid to
him had he continued as an Employee to the end of the Performance Period.
In the event a Participant terminates employment for any other reason, any
amounts for outstanding Performance Periods shall be forfeited as of
Termination of Employment.

Section 12.    General Provisions

     (a)  Withholding.  The Employer shall have the right to deduct from all
amounts paid to a Participant in cash any taxes required by law to be
withheld in respect of Awards under this Plan.  In the case of payments of
Awards in the form of Common Stock, the Committee shall require the
Participant to pay to the Employer the amount of any taxes required to be
withheld with respect to such Common Stock, or, in lieu thereof, the
Employer shall have the right to retain (or the Participant may be offered
the opportunity to elect to tender) the number of shares of Common Stock
whose Fair Market Value equals the amount required to be withheld.

     (b)  Awards.  Each Award shall be evidenced in writing delivered to the
Participant and shall specify the terms and conditions and any rules
applicable to such Award.

     (c)  Nontransferability.  Except as provided in Section 6(d), no Award
shall be assignable or transferable, and no right or interest of any
Participant shall be subject to any lien, obligation or liability of the
Participant, except by will or the laws of descent and distribution.

     (d)  No Rights as Stockholder.  Subject to the provisions of the
applicable Award, no Participant or Designated Beneficiary shall have any
rights as a stockholder with respect to any shares of Common Stock to be
distributed under the Plan until becoming the holder.  Notwithstanding the
foregoing, in connection with each grant of Restricted Stock hereunder, the
applicable Award shall specify if and to what extent the Participant shall
not be entitled to the rights of a stockholder in respect of such Restricted
Stock.

     (e)  Construction of the Plan.  The validity, construction,
interpretation, administration and effect of the Plan and of its rules and
regulations, and rights relating to the Plan, shall be determined solely in
accordance with the laws of Utah.

     (f)  Effective Date.  Subject to the approval of the stockholders of
the Company, the Plan shall be effective on March 1, 1991.  No Options or
Awards may be granted under the Plan, however, until the Plan is approved by
the Company's shareholders or after May 20, 2001.

     (g)  Amendment of Plan.  The Board of Directors may amend, suspend or
terminate the Plan or any portion thereof at any time, provided that no
amendment shall be made without stockholder approval if such approval is
necessary to comply with any tax or regulatory requirement, including for
these purposes any approval requirement that is a prerequisite for exemptive
relief under Section 16(b) of the Securities Exchange Act of 1934.

     (h)  Amendment of Award.  The Committee may amend, modify or terminate
any outstanding Award with the Participant's consent at any time prior to
payment or exercise in any manner not inconsistent with the terms of the
Plan, including without limitation, to change the date or dates as of which
an Option or Right becomes exercisable; a Performance Share is deemed
earned; Restricted Stock becomes nonforfeitable; or to cancel and reissue an
Award under such different terms and conditions as it determines appropriate.

Section 13.    Change of Control.

     In the event of a Change of Control of the Company, all Options,
Restricted Stock, and other Awards granted under the Plan shall vest
immediately.

     A Change in Control of the Company shall be deemed to have occurred if
(i) any "Acquiring Person" (as such term is defined in the Rights Agreement
dated as of February 13, 1996, between the Company and ChaseMellon
Shareholder Services L.L.C. ("Rights Agreement")) is or becomes the
beneficial owner (as such term is used in Rule 13d-3 under the Securities
Exchange Act of 1934) of securities of the Company representing 25 percent
or more of the combined voting power of the Company; or (ii) the following
individuals cease for any reason to constitute a majority of the number of
directors then serving:  individuals who, as of May 19, 1998, constitute the
Company's Board of Directors and any new director (other than a director
whose initial assumption of office is in connection with an actual or
threatened election contest, including but not limited to a consent
solicitation, relating to the election of directors of the Company) whose
appointment or election by the Board or nomination for election by the
Company's stockholders was approved or recommended by a vote of at least
two-thirds of the directors then still in office who either were directors
on May 19, 1998, or whose appointment, election or nomination for election
was previously so approved or recommended; or (iii) the Company's
stockholders approve a merger or consolidation of the Company or any direct
or indirect subsidiary of the Company with any other corporation, other than
a merger or consolidation that would result in the voting securities of the
Company outstanding immediately prior to such merger or consolidation
continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity or any parent
thereof) at least 60 percent of the combined voting power of the securities
of the Company or such surviving entity or its parent outstanding
immediately after such merger or consolidation, or a merger or consolidation
effected to implement a recapitalization of the Company (or similar
transaction) in which no person is or becomes the beneficial owner, directly
or indirectly, of securities of the Company representing 25 percent or more
of the combined voting power of the Company's then outstanding securities;
or (iv) the Company's stockholders approve a plan of complete liquidation or
dissolution of the Company or there is consummated an agreement for the sale
or disposition by the Company of all or substantially all of the Company's
assets, other than a sale or disposition by the Company of all or
substantially all of the Company's assets to an entity, at least 60 percent
of the combined voting power of the voting securities of which are owned by
stockholders of the Company in substantially the same proportions as their
ownership of the Company immediately prior to such sale.  A Change in
Control, however, shall not be considered to have occurred until all
conditions precedent to the transaction, including but not limited to, all
required regulatory approvals have been obtained.
