                          1999 OMNIBUS STOCK INCENTIVE PLAN


1.   ESTABLISHMENT AND PURPOSE.

     There is hereby adopted the Sento Corporation 1999 Omnibus Stock Incentive
Plan (the "PLAN").  The Plan shall be the successor to the Stock Incentive Plan,
as amended and restated on August 11, 1998 (the "PREDECESSOR PLAN").  Upon
adoption of the Plan by the Board of Directors and approval of the Plan by
stockholders of Sento Corporation (the "COMPANY"), no further awards shall be
made under the Predecessor Plan.  If the Plan is not approved by the
stockholders of the Company, the Predecessor Plan shall remain in full force and
effect.  The Plan is intended to promote the interests of the Company and the
stockholders of the Company by providing officers and other employees of the
Company (including directors who are also employees of the Company) and persons
who are expected to make a long-term contribution to the success of the Company
with appropriate incentives and rewards to encourage them to enter into and
continue in the employ of the Company and/or to acquire a proprietary interest
in the long-term success of the Company, thereby aligning their interest more
closely to the interest of stockholders.

2.   DEFINITIONS.

     As used in the Plan, the following definitions apply to the terms indicated
below:

     (a)  "AWARD AGREEMENT" shall mean the written agreement between the Company
          and a Participant evidencing an Incentive Award.

     (b)  "BOARD OF DIRECTORS" shall mean the Board of Directors of the Company
          or any Subsidiary of the Company as the case may be.

          Participant's employment by the Company, shall mean (i) the willful
          and continued failure by the Participant substantially to perform his
          duties and obligations to the Company (other than any such failure
          resulting from his incapacity due to physical or mental illness) or
          (ii) the willful engaging by the Participant in misconduct which is
          materially injurious to the Company.  For purposes of this Section
          2(c), no act, or failure to act, on a Participant's part shall be
          considered "willful" unless done, or omitted to be done, by the
          Participant in bad faith and without reasonable belief that his action
          or omission was in the best interest of the Company.  The Committee
          shall determine whether a termination of employment is for Cause.

     (d)  "CHANGE IN CONTROL" shall mean any of the following occurrences:

          the Company or any corporation owned, directly or indirectly, by the

          their ownership of stock of the Company), is or becomes the

          a person who has entered into an agreement with the Company to effect

          more than 50% of the  combined voting power of the voting securities
          of the Company or such surviving entity outstanding immediately after
          such merger or consolidation or (B) a merger or consolidation effected
          to implement a recapitalization of the Company (or similar

          outstanding securities; or

                (iv) the stockholders of the Company approve, and the Company

3.   STOCK SUBJECT TO THE PLAN.

     (a)  SHARES AVAILABLE FOR AWARDS.

          The maximum number of shares of Common Stock reserved for issuance
          under the Plan shall be 3,500,000 shares (subject to adjustment as
          provided herein), which shall include 2,500,000 shares authorized but
          unissued under the Predecessor Plan.  The total number of


                                       4
<PAGE>

          shares reserved for issuance hereunder may be authorized but unissued
          Common Stock or authorized and issued Common Stock held in the
          Company's treasury or acquired by the Company for the purposes of the
          Plan.  The Committee may direct that any stock certificate evidencing
          shares issued pursuant to the Plan shall bear a legend setting forth

          number of shares of Common Stock as to which the Tandem SAR is
          exercised and, notwithstanding the foregoing, such number of shares
          shall no longer be available for Incentive Awards under the Plan.

     (b)  ADJUSTMENT FOR CHANGE IN CAPITALIZATION.

          In the event that the Committee shall determine that any dividend or
          other distribution (whether in the form of cash, Common Stock, or
          other property), recapitalization, stock split, reverse stock split,
          reorganization, merger, consolidation, spin-off, combination,
          repurchase, or share exchange, or other similar corporate transaction
          or event, affects the Common Stock such that an adjustment is
          appropriate in order to prevent dilution or enlargement of the rights
          of Participants under the Plan, then the Committee shall make such
          equitable changes or adjustments as it deems necessary or appropriate
          to any or all of (i) the number and kind of shares of stock which may
          thereafter be issued in connection with Incentive Awards, (ii) the
          number and kind of shares of stock issued or issuable in respect of
          outstanding Incentive Awards, and (iii) the exercise price, grant
          price, or purchase price relating to any Incentive Award; provided
          that, with respect to Incentive Stock Options, such adjustment shall
          be made in accordance with Section 424 of the Code.

     (c)  RE-USE OF SHARES.

          Subject to the last sentence of Section 3(a), the following shares of
          Common Stock shall again become available for Incentive Awards:  any
          shares subject to an Incentive Award that remain unissued upon the
          cancellation, surrender, exchange or termination of such award for any
          reason whatsoever; any shares of Restricted Stock forfeited; and any
          shares in respect of which a Stand-Alone SAR.

express provisions of the Plan, to administer the Plan and to exercise all the
powers and authorities either specifically granted to it under the Plan or
necessary or advisable in the administration of the Plan, including, without
limitation, the authority to grant Incentive Awards; to determine the persons to
whom and the time or times at which Incentive Awards shall be granted; to
determine the type and number of Incentive Awards to be granted, the number of
shares of Stock to which an Award may relate and the terms, conditions,
restrictions and performance criteria relating to any Incentive Award; to
determine whether, to what extent, and under what circumstances an Incentive
Award may be settled, canceled, forfeited, exchanged, or surrendered; to make
adjustments in the performance goals in


                                       5
<PAGE>

recogintion of unusual or non-recurring events affecting the Company or the
financial statements of the Company (to the extent in accordance with Section
162(m)of the Code, if applicable), or in response to changes in applicable
laws, regulations, or accounting principles; to construe and interpret the
Plan and any Incentive Award; to prescribe, amend and rescind rules and
regulations relating to the Plan; to determine the terms and provisions of
Award Agreements; and to make all other determinations deemed necessary or
advisable for the administration of the Plan.

     The Committee may, in its absolute discretion, without amendment to the
Plan, (i) accelerate the date on which any Tandem SAR or Stand-Alone SAR or
Incentive Award relating to Phantom Stock granted under the Plan becomes
exercisable, waive or amend the operation of Plan provisions respecting exercise
after termination of employment or otherwise adjust any of the terms of such
Tandem SAR relating to Non-Qualified Stock Options or Stand-Alone SAR or
Incentive Award relating to Phantom Stock, and (ii) accelerate the Exercise Date
or Issue Date, or waive any condition imposed hereunder, with respect to any
share of Restricted Stock or Phantom Stock or otherwise adjust any of the terms
applicable to such share.

     No member of the Committee shall be liable for any action, omission or
determination relating to the Plan, and the Company shall indemnify and hold
harmless each member of the Committee and each other director or employee of the
Company to whom any duty or power relating to the administration or
interpretation of the Plan has been delegated against any cost or expense
(including counsel fees) or liability (including any sum paid in settlement of a
claim with the approval of the Committee) arising out of any action, omission or
determination relating to the Plan, if, in either case, such action, omission or
determination was taken or made by such member, director or employee in good
faith and in a manner such member, director or employee reasonably believed to
be in or not opposed to the best interests of the Company.

5.   ELIGIBILITY.

     The persons who shall be eligible to receive Incentive Awards pursuant to
the Plan shall be such Participants as the Committee shall select from time to
time. Notwithstanding the foregoing, only individuals who are employees of the
Company or any Subsidiary of the Company as of the date of the grant of any
Incentive Stock Option shall be eligible to receive such Incentive Stock
Options.

6.   AWARDS UNDER THE PLAN; AWARD AGREEMENT.

     The Committee may grant Options, Tandem SARs, Stand-Alone SARs, shares of
Restricted Stock, shares of Phantom Stock and Stock Bonuses, in such amounts and
with such terms and conditions as the Committee shall determine, subject to the
provisions of the Plan.

     Each Incentive Award granted under the Plan (except an unconditional Stock
Bonus) shall be evidenced by an Award Agreement which shall contain such
provisions as the Committee may in its sole discretion deem necessary or
desirable.  By accepting an Incentive Award, a Participant thereby agrees that
the award shall be subject to all of the terms and provisions of the Plan and
the applicable Award Agreement.

7.   OPTIONS.


                                       6
<PAGE>

     (a)  IDENTIFICATION OF OPTIONS.

          Each Option shall be clearly identified in the applicable Award
          Agreement as either an Incentive Stock Option or a Non-Qualified Stock
          Option.

     (b)  EXERCISE PRICE.

          Each Award Agreement with respect to an Option shall set forth the
          amount (the "OPTION EXERCISE PRICE") payable by the grantee to the
          Company upon exercise of the Option.  The Option Exercise Price per
          share shall be determined by the Committee; provided, however, that in
          the case of an Incentive Stock Option, the Option Exercise Price shall
          in no event be less than the Fair Market Value of a share of Common
          Stock on the date the Option is granted.

     (c)  TERM AND EXERCISE OF OPTIONS.

               (1)  The Committee shall determine the vesting schedule and
          expiration date of each Option; provided, however, that no Incentive
          Stock Option shall be exercisable more than 10 years after the date of
          grant.

               (2)  An Option may be exercised for all or any portion of the
          shares as to which it is exercisable, provided, that no partial
          exercise of an Option shall be for an aggregate exercise price of less
          than $1,000.  The partial exercise of an Option shall not cause the
          expiration, termination or cancellation of the remaining portion
          thereof.

               (3)  An Option shall be exercised by delivering notice (in the
          form attached to the Award Agreement, if a form of notice is attached)
          to the Company's principal office, to the attention of its Secretary,
          no less than one business day in advance of the effective date of the
          proposed exercise.  Such notice shall specify the number of shares of
          Common Stock with respect to which the Option is being exercised and
          the effective date of the proposed exercise and shall be signed by the
          Participant or other person then having the right to exercise the
          Option.  Such notice may be withdrawn at any time prior to the close
          of business on the business day immediately preceding the effective
          date of the proposed exercise.  Payment for shares of Common Stock
          purchased upon the exercise of an Option shall be made on the
          effective date of such exercise by one or a combination of the
          following means: (i) in cash, by certified check, bank cashier's check
          or wire transfer; (ii) by delivering a properly executed exercise
          notice to the Company together with a copy of irrevocable instructions
          to a broker to deliver promptly to the Company the amount of sale or
          loan proceeds to pay the full amount of the purchase price, (iii) by
          delivering shares of Common Stock owned by the Participant with
          appropriate stock powers, (iv) by electing to have the Company retain
          shares of Common Stock which would otherwise be issued on the exercise
          of the Option, or (v) any combination of the foregoing forms.  In
          determining the number of shares of Common Stock necessary to be
          delivered to or retained by the Company, such shares shall be valued
          at their Fair Market Value as of the exercise date.


                                       7
<PAGE>

               (4)  Certificates for shares of Common Stock purchased upon the
          exercise of an Option shall be issued in the name of the Participant
          or other person entitled to receive such shares, and delivered to the
          Participant or such other person as soon as practicable following the
          effective date on which the Option is exercised.

     (d)  LIMITATIONS ON INCENTIVE STOCK OPTIONS.

               (1)  To the extent that the aggregate Fair Market Value of shares
          of Common Stock with respect to which Incentive Stock Options are
          exercisable for the first time by a Participant during any calendar
          year under the Plan and any other stock option plan of the Company (or
          any Subsidiary of the Company) shall exceed $100,000, such Options
          shall be treated as Non-Qualified Stock Options.  Such Fair Market
          Value shall be determined as of the date on which each such Incentive
          Stock Option is granted.

               (2)  No Incentive Stock Option may be granted to an individual
          if, at the time of the grant, such individual owns stock possessing
          more than 10 percent of the total combined voting power of all classes
          of stock of the Company unless (i) the exercise price per share of
          such Incentive Stock Option is at least 110 percent of the Fair Market
          Value of a share of Common Stock at the time such Incentive Stock
          Option is granted and (ii) such Incentive Stock Option is not
          exercisable after the expiration of 5 years from the date such
          Incentive Stock Option is granted.

               (1)  Unless the applicable Award Agreement provides otherwise and
          except as provided by Sections 7(g) and 9(d) with respect to a Change
          of Control, in the event that the employment of a Participant with the
          Company or a Subsidiary of the Company shall be terminated by the
          employee or by the Company for Cause (i) Options granted to such
          Participant, to the extent that they are exercisable at the time of
          such termination, shall remain exercisable until the date that is 30
          days after such termination, on which date they shall expire, and (ii)
          Options granted to such Participant, to the extent that they were not
          exercisable at the time of such termination, shall expire at the close
          of business on the date of such termination.  Notwithstanding the
          foregoing, no Option shall be exercisable after the expiration of its
          term.

               (2)  Unless the applicable Award Agreement provides otherwise, in
          the event that the employment of a Participant with the Company or a
          Subsidiary of the Company shall  terminate on account of the
          Disability or death of the Participant (i) Options granted to such
          Participant, to the extent that they were exercisable at the time of
          such termination, shall remain exercisable until the first anniversary
          of such termination, on which date they shall expire, and (ii) Options
          granted to such Participant, to the extent that they were not
          exercisable at the time of such termination, shall expire at the close
          of business on the date of such termination. Notwithstanding the
          foregoing, no Option shall be exercisable after the expiration of its
          term.


                                       8
<PAGE>

               (3)  Unless the applicable Award Agreement provides otherwise and
          except as provided by Sections 7(g) and 9(d), in the event that the
          employment of a Participant with the Company or a Subsidiary of the
          Company shall terminated by the Company in connection with a reduction
          in force or for any other reason other than death, Disability or
          Cause, (i) Options granted to such Participant, to the extent that
          they are exercisable at the time of such termination, shall remain
          exercisable until the date that is 90 days after such termination, on
          which date they shall expire, and (ii) Options granted to such
          Participant, to the extent that they were not exercisable at the time
          of such termination, shall expire at the close of business on the date
          of such termination.  Notwithstanding the foregoing, no Option shall
          be exercisable after the expiration of its term.

     (f)  EFFECT OF REMOVAL FROM BOARD OF DIRECTORS

          Unless the applicable Award Agreement provides otherwise, in the event
          a Director ceases to serve on the Board of Directors, the Committee
          shall determine the effect such termination has with respect to
          Options granted to such Director; PROVIDED, that (i) Options granted
          to such Director, to the extent that they were not exercisable at the
          time of such termination, shall expire at the close of business on the
          date of such termination and (ii) no Option shall be exercisable after
          the expiration of its term.  Notwithstanding the foregoing, Options
          granted to a Director while such Director was also an employee of the
          Company or any Subsidiary of the Company shall be governed by the
          provisions set forth in Section 7(e).

     (g)  ACCELERATION OF EXERCISE DATE UPON CHANGE IN CONTROL.

               (1)  Upon the occurrence of a Change in Control described in
          Section 2(d)(i), (ii), or (iii), if, (A) the Company, any Subsidiary

          is merged or consolidated requires such Participant to move more than
          50 miles from such Participant's place of residence within 1 year of
          the Change in Control; or (B) notwithstanding Section 7(e)(1)(ii), the
          employment of the Participant with the Company, any Subsidiary of the

          Control; or (C) the Participant is required to change assignments
          within the Company, any Subsidiary of the Company or any entity into
          which the Company or any Subsidiary is merged or consolidated and is
          given lower responsibilities as a result of such change within 1 year
          of the Change in Control, then each Option granted under the Plan and
          outstanding at such time shall become fully and immediately
          exercisable and shall remain exercisable until the later of (Y) 30
          days following the occurrence of said Change in Control, and (Z) 30
          days following the occurrence of the change described in (A), (B), or
          (C) above.  Notwithstanding the foregoing, no Option shall be
          exercisable after the expiration of its term.

               (2)  Upon the occurrence of a Change in Control to which Section
          7(g)(1) does not apply, each Option granted under the Plan and
          outstanding at such time shall be treated as provided by any written
          plan or agreement approved by the stockholders pursuant to which such
          Change in Control occurs; provided, that if such Change in Control is
          not


                                       9
<PAGE>

          governed by any plan or agreement approved by the stockholders, the
          erms and conditions, including the vesting and expiration, of each
          Option shall not be affected by such Change in Control.

8.   TANDEM SARS.

     The Committee may grant in connection with any Option granted hereunder one
or more Tandem SARs relating to a number of shares of Common Stock less than or
equal to the number of shares of Common Stock subject to the related Option.  A
Tandem SAR may be granted at the same time as, or, in the case of a
Non-Qualified Stock Option, subsequent to the time that, its related Option is
granted.

     (a)  BENEFIT UPON EXERCISE.

          The exercise of a Tandem SAR with respect to any number of shares of
          Common Stock shall entitle the Participant to a cash payment, for each
          such share, equal to the excess of (i) the Fair Market Value of a
          share of Common Stock on the exercise date over (ii) the Option
          Exercise Price per share of the related Option.  Such payment shall be
          made as soon as practicable after the effective date of such exercise.

     (b)  TERM AND EXERCISE OF TANDEM SAR.

               (1)  A Tandem SAR shall be exercisable (i) only if and to the
          extent that its related Option is exercisable and (ii) only if at the
          time of such exercise, the Fair Market Value of a share of Common
          Stock exceeds the Option Exercise Price per share of the related
          Option.

               (2)  The exercise of a Tandem SAR with respect to a number of
          shares of Common Stock shall cause the immediate and automatic
          cancellation of its related Option with respect to an equal number of
          shares.  The exercise of an Option, or the cancellation, termination
          or expiration of an Option (other than pursuant to this Section
          8(b)(2)), with respect to a number of shares of Common Stock shall
          cause the automatic and immediate cancellation of any related Tandem
          SARs to the extent that the number of shares of Common Stock remaining
          subject to such Option is less than the number of shares then subject
          to such Tandem SAR.  Such Tandem SARs shall be canceled in the order
          in which they become exercisable.

               (3)  A Tandem SAR may be exercised for all or any portion of the
          shares as to which the related Option is exercisable; provided, that
          no partial exercise of a Tandem SAR shall be for less than a number of
          shares having an aggregate option exercise price of less than $1,000.
          The partial exercise of a Tandem SAR shall not cause the expiration,
          termination or cancellation of the remaining portion thereof.

               (4)  No Tandem SAR shall be assignable or transferable otherwise
          than together with its related Option, and any such transfer or
          assignment will be subject to the provisions of Section 20 of the
          Plan.


                                       10
<PAGE>

               (5)  A Tandem SAR shall be exercised by delivering notice to the
          Company's principal office, to the attention of its Secretary, no less
          than one business day in advance of the effective date of the proposed
          exercise.  Such notice shall specify the number of shares of Common
          Stock with respect to which the Tandem SAR is being exercised and the
          effective date of the proposed exercise and shall be signed by the
          Participant or other person then having the right to exercise the
          Option to which the Tandem SAR is related.  Such notice may be
          withdrawn at any time prior to the close of business on the business
          day immediately preceding the effective date of the proposed exercise.

9.   STAND-ALONE SARS.

     (a)  BENEFIT UPON EXERCISE.

          The exercise of a Stand-Alone SAR with respect to any number of shares
          of Common Stock shall entitle the Participant to a cash payment, for
          each such share, equal to the excess of (i) the Fair Market Value of a
          share of Common Stock on the exercise date over (ii) the Reference
          Value of the Stand-Alone SAR.  Such payments shall be made as soon as
          practicable after the effective date of such exercise.

     (b)  TERM AND EXERCISE OF STAND-ALONE SARS.

               (1)  Unless the applicable Award Agreement provides otherwise, a
          Stand-Alone SAR shall become cumulatively exercisable as to 25 percent
          of the shares covered thereby on each of the first, second, third and
          fourth anniversaries of the date of grant.   The Committee shall
          determine the expiration date of each Stand-Alone SAR.  Unless the
          applicable Award Agreement provides other wise, no Stand-Alone SAR
          shall be exercisable prior to the date of grant.

               (2)  A Stand-Alone SAR may be exercised for all or any portion of
          the shares as to which it is exercisable; provided, that no partial
          exercise of a Stand-Alone SAR shall be for an aggregate Reference
          Value of less than $1,000.  The partial exercise of a Stand-Alone SAR
          shall not cause the expiration, termination or cancellation of the
          remaining portion thereof.

               (3)  A Stand-Alone SAR shall be exercised by delivering notice to
          the Company's principal office, to the attention of its Secretary, no
          less than one business day in advance of the effective date of the
          proposed exercise.  Such notice shall specify the number of shares of
          Common Stock with respect to which the Stand-Alone SAR is being
          exercised, and the effective date of the proposed exercise, and shall
          be signed by the Participant.  The Participant may withdraw such
          notice at any time prior to the close of business on the business day
          immediately preceding the effective date of the proposed exercise.

     (c)  EFFECT OF TERMINATION OF EMPLOYMENT OR REMOVAL FROM BOARD OF
          DIRECTORS.

          The provisions set forth in Section 7(e) and 7(f) with respect to the
          exercise of Options shall apply as well to the exercise of Stand-Alone
          SARs.

     (d)  ACCELERATION OF EXERCISE DATE UPON CHANGE IN CONTROL.

          The provisions set forth in Section 7(g) with respect to the exercise

10.  RESTRICTED STOCK.

     (a)  ISSUE DATE AND VESTING DATE.

          At the time of the grant of shares of Restricted Stock, the Committee
          shall establish an Issue Date or Issue Dates and a Vesting Date or
          Vesting Dates with respect to such shares.  The Committee may divide
          such shares into classes and assign a different Issue Date and/or
          Vesting Date for each class.  If the grantee is employed by the
          Company or a Subsidiary of the Company on an Issue Date (which may be
          the date of grant), the specified number of shares of Restricted Stock
          shall be issued in accordance with the provisions of Section 10(e) of
          the Plan.  Provided that all conditions to the vesting of a share of
          Restricted Stock imposed pursuant to Section 10(b) of the plan are
          satisfied, and except as provided in Section 10(g) of the Plan, upon
          the occurrence of the Vesting Date with respect to a share of
          Restricted Stock, such share shall vest and the restrictions of
          Section 10(c) of the Plan shall lapse.

     (b)  CONDITIONS TO VESTING.

          At the time of the grant of shares of Restricted Stock, the Committee
          may impose such restrictions or conditions to the vesting of such
          shares as it, in its absolute discretion, deems appropriate.

     (c)  RESTRICTIONS ON TRANSFER PRIOR TO VESTING.

          Prior to the vesting of a share of Restricted Stock, no transfer of a
          Participant's rights with respect to such share, whether voluntary or
          involuntary, by operation of law or otherwise, shall be permitted.
          Immediately upon any attempt to transfer such rights, such share, and
          all of the rights related thereto, shall be forfeited by the
          Participant.

     (d)  DIVIDENDS ON RESTRICTED STOCK.

          The Committee in its discretion may require that any dividends paid on
          shares of Restricted Stock shall be held in escrow until all
          restrictions on such shares have lapsed.

     (e)  ISSUANCE OF CERTIFICATES.


                                       12
<PAGE>

               (1)  Reasonably promptly after the Issue Date with respect to
          shares of Restricted Stock, the Company shall cause to be issued a
          stock certificate, registered in the name of the Participant to whom
          such shares were granted, evidencing such shares; provided, that the
          Company shall not cause such a stock certificate to be issued unless
          it has received a stock power duly endorsed in blank with respect to
          such shares.  Each such stock certificate shall bear the following
          legend:

               The transferability of this certificate and the
               shares of stock represented hereby are subject to
               the restrictions, terms and conditions (including
               forfeiture provisions and restrictions against
               transfer) contained in the 1999 Omnibus Stock
               Incentive Plan of Sento Corporation (the
               "Company") and an Award Agreement entered into
               between the registered owner of such shares and
               the Company.  A copy of such Plan and Award
               Agreement is on file in the office of the
               Secretary of the Company, 808 East Utah Valley
               Drive, American Fork, Utah 84003.

          Such legend shall not be removed until such shares vest pursuant to
          the terms of the applicable Award Agreement.

               (2)  Each certificate issued pursuant to this Section 10(e),
          together with the stock powers relating to the shares of Restricted
          Stock evidenced by such certificate, shall be held by the Company
          unless the Committee determines otherwise.

     (f)  CONSEQUENCES OF VESTING.

          Upon the vesting of a share of Restricted Stock pursuant to the terms
          of the applicable Award Agreement, the restrictions of Section 10(c)
          of the Plan shall lapse.  Reasonably promptly after a share of
          Restricted Stock vests, the Company shall cause to be delivered to the
          Participant to whom such shares were granted, a certificate evidencing
          such share, free of the legend set forth in Section 10(e) of the Plan.

     (g)  EFFECT OF TERMINATION OF EMPLOYMENT OR REMOVAL FROM BOARD OF
          DIRECTORS.

               (1) Unless the applicable Award Agreement provides otherwise, the
          Committee shall determine, upon the termination of a Participant's
          employment by the Company or any Subsidiary of the Company for any
          reason other than Cause, any and all shares to which restrictions on
          transferability apply shall be immediately forfeited by the
          Participant and transferred to the Company, provided that if the
          Committee, in its sole discretion and within 30 days after such
          termination of employment notifies the Participant in writing of its
          decision not to terminate the Participant's rights in such shares,
          then the Participant shall continue to be the owner of such shares
          subject to such continuing restrictions as the Committee may prescribe
          in such notice.  If shares of Restricted Stock are forfeited in
          accordance with the provision of this Section 10, the Company shall
          also have the right to


                                       13
<PAGE>

          require the return of all dividends paid on such shares, whether by
          termination of any escrow arrangement under which such dividends are
          held or otherwise.

               (2)  In the event of the termination of a Participant's
          employment for Cause, all shares of Restricted Stock granted to such
          Participant which have not vested as of the date of such termination
          shall immediately be returned to the Company, together with any
          dividends paid on such shares.

               (3) Unless the applicable Award Agreement provides otherwise, the
          Committee shall determine the effect the removal of a Director from
          the Board of Directors shall have on such Director's Restricted Stock
          award.  Notwithstanding the foregoing, Restricted Stock awards granted
          to a Director while such Director was also an employee of the Company
          or any Subsidiary of the Company shall be governed by the provisions
          set forth in this Section 10(g)(1) and (2).

     (h)  EFFECT OF CHANGE IN CONTROL.

               (1)  Upon the occurrence of a Change in Control described in
          Section 2(d)(i), (ii), or (iii), if, (A) the Company, any Subsidiary
          of the Company or any entity into which the Company or any Subsidiary
          is merged or consolidated requires such Participant to move more than
          50 miles from such Participant's place of residence within 1 year of
          the Change in Control; or (B) notwithstanding Section 10(g), the
          employment of the Participant with the Company, any Subsidiary of the
          Company or any entity into which the Company or any Subsidiary is
          merged or consolidated is terminated within 1 year of the Change in
          Control; or (C) the Participant is required to change assignments
          within the Company, any Subsidiary of the Company or any entity into
          which the Company or any Subsidiary is merged or consolidated and is
          given lower responsibilities as a result of such change within 1 year
          of the Change in Control, then each share of Restricted Stock granted
          under the Plan and outstanding at such time shall immediately vest and
          all restrictions on such shares shall immediately lapse.

               (2)  Upon the occurrence of a Change in Control to which Section
          10(h)(1) does not apply, each share of Restricted Stock granted under
          the Plan and outstanding at such time shall be treated as provided by
          any written plan or agreement approved by the stockholders pursuant to
          which such Change in Control occurs; provided, that if such Change in
          Control is not governed by any plan or agreement approved by the
          stockholders, the terms and conditions, including the vesting and
          expiration, of each share of Restricted Stock shall not be affected by
          such Change in Control.

     (i)  SPECIAL PROVISIONS REGARDING RESTRICTED STOCK AWARDS.

          Notwithstanding anything to the contrary contained herein, Restricted
          Stock granted pursuant to this Section 10 shall be based on the
          attainment by the Company (or a Subsidiary or division of the Company
          if applicable) of performance goals pre-established by the Committee,
          based on one or more of the following criteria: (i) the attainment of
          a specified percentage return on total stockholder equity of the
          Company or any Subsidiary


                                       14
<PAGE>

          of the Company; (ii) the attainment of a specified percentage
          increase in earnings per share of Common Stock; (iii) the attainment
          of a specified percentage increase in net income of the Company or
          any Subsidiary of the Company; and (iv) the attainment of a specified
          percentage increase in profit before taxation of the Company or any
          Subsidiary of the Company.  Attainment of any such performance
          criteria shall be determined in accordance with generally accepted
          accounting principles as in effect from time to time.  Such shares of
          Restricted Stock shall be released from restrictions only after the
          attainment of such performance measures have been certified by the
          Committee.

11.  PHANTOM STOCK.

     (a)  VESTING DATE.

          At the time of the grant of shares of Phantom Stock, the Committee
          shall establish a Vesting Date or Vesting Dates with respect to such
          shares.  The Committee may divide such shares into classes and assign
          a different Vesting Date for each class.  Provided that all conditions
          to the vesting of a share of Phantom Stock imposed pursuant to Section
          11(c) of the Plan are satisfied, and except as provided in Section
          11(d) of the Plan, upon the occurrence of the Vesting Date with
          respect to a share of Phantom Stock, such share shall vest.

     (b)  BENEFIT UPON VESTING.

          Upon the vesting of a share of Phantom Stock, the Participant shall be
          entitled to receive in cash, within 30 days of the date on which such
          share vests, an amount equal to the sum of (i) the Fair Market Value
          of a share of Common Stock on the date on which such share of Phantom
          Stock vests and (ii) the aggregate amount of cash dividends paid with
          respect to a share of Common Stock during the period commencing on the
          date on which the share of Phantom Stock was granted and terminating
          on the date on which such share vests.

     (c)  CONDITIONS TO VESTING.

          At the time of the grant of shares of Phantom Stock, the Committee may
          impose such restrictions or conditions to the vesting of such shares
          as it, in its absolute discretion, deems appropriate.

     (d)  EFFECT OF TERMINATION OF EMPLOYMENT OR REMOVAL FROM BOARD OF
          DIRECTORS.

               (1) Unless the applicable Award Agreement provides otherwise,
          shares of Phantom Stock that have not vested, together with any
          dividends credited on such shares, shall be forfeited upon the
          Participant's termination of employment for any reason.

               (2) Unless the applicable Award Agreement provides otherwise, the
          Committee shall determine the effect the removal of a Director from
          the Board of Directors shall have on such Director's Phantom Stock
          award.  Notwithstanding the foregoing, Phantom Stock awards granted to
          a Director while such Director was also an employee of the Company or


                                       15
<PAGE>

          any Subsidiary of the Company shall be governed by the provisions set
          forth in this Section 11(d)(1).


     (e)  EFFECT OF CHANGE IN CONTROL.

               (1)  Upon the occurrence of a Change in Control described in
          Section 2(d)(i), (ii), or (iii), if, (A) the Company, any Subsidiary
          of the Company or any entity into which the Company or any Subsidiary
          is merged or consolidated requires such Participant to move more than
          50 miles from such Participant's place of residence within 1 year of
          the Change in Control; or (B) notwithstanding Section 11(d), the
          employment of the Participant with the Company, any Subsidiary of the
          Company or any entity into which the Company or any Subsidiary is
          merged or consolidated is terminated within 1 year of the Change in
          Control; or (C) the Participant is required to change assignments
          within the Company, any Subsidiary of the Company or any entity into
          which the Company or any Subsidiary is merged or consolidated and is
          given lower responsibilities as a result of such change within 1 year
          of the Change in Control, then each share of Phantom Stock granted
          under the Plan and outstanding at such time shall immediately vest.

               (2)  Upon the occurrence of a Change in Control to which Section
          11(e)(1) does not apply, each share of Phantom Stock granted under the
          Plan and outstanding at such time shall be treated as provided by any
          written plan or agreement approved by the stockholders pursuant to
          which such Change in Control occurs; provided, that if such Change in
          Control is not governed by any plan or agreement approved by the
          stockholders, the terms and conditions, including the vesting and
          expiration, of each share of Phantom Stock shall not be affected by
          such Change in Control.

     (f)  SPECIAL PROVISIONS REGARDING PHANTOM STOCK AWARDS.

          Notwithstanding anything to the contrary contained herein, Phantom
          Stock granted pursuant to this Section 11 to officers of the Company
          or any Subsidiary of the Company shall be based on the attainment by
          the Company or any Subsidiary of the Company of performance goals
          pre-established by the Committee, based on one or more of the
          following criteria: (i) the attainment of a specified percentage
          return on total stockholder equity of the Company or any Subsidiary of
          the Company; (ii) the attainment of a specified percentage increase in
          earnings per share of Common Stock from continuing operations; (iii)
          the attainment of a specified percentage increase in net income of the
          Company or any Subsidiary of the Company; and (iv) the attainment of a
          specified percentage increase in profit before taxation of the Company
          or any Subsidiary of the Company.  Attainment of any such performance
          criteria shall be determined in accordance with generally accepted
          accounting principles as in effect from time to time.  No cash payment
          in respect of any Phantom Stock award will be paid to any such officer
          until the attainment of the respective performance measures have been
          certified by the Committee.

12.  STOCK BONUSES.


                                       16
<PAGE>

     In the event that the Committee grants a Stock Bonus, a certificate for the
shares of Common Stock comprising such Stock Bonus shall be issued in the name
of the Participant to whom such grant was made and delivered to such Participant
as soon as practicable after the date on which such Stock Bonus is payable.

13.  RIGHTS AS A STOCKHOLDER.

     No person shall have any rights as a stockholder with respect to any shares
of Common Stock covered by or relating to any Incentive Award until the date of
issuance of a stock certificate with respect to such shares.  Except as
otherwise expressly provided in Section 3(b) of the Plan, no adjustment to any
Incentive Award shall be made for dividends or other rights for which the record
date occurs prior to the date such stock certificate is issued.

14.  NO SPECIAL EMPLOYMENT RIGHTS; NO RIGHT TO INCENTIVE AWARD.

     Nothing contained in the Plan or any Award Agreement shall confer upon any
Participant any right with respect to the continuation of employment by the
Company or any Subsidiary of the Company or interfere in any way with the right
of the Company or any Subsidiary of the Company, subject to the terms of any
separate employment agreement to the contrary, at any time to terminate such
employment or to increase or decrease the compensation of the Participant.  No
person shall have any claim or right to receive an Incentive Award hereunder.
The Committee's granting of an Incentive Award to a Participant at any time
shall neither require the Committee to grant any other Incentive Award to such
Participant or other person at any time or preclude the Committee from making
subsequent grants to such Participant or any other person.

15.  SECURITIES MATTERS.

     (a)  The Company shall be under no obligation to effect the registration
          pursuant to the Securities Act of any interests in the Plan or any
          shares of Common Stock to be issued hereunder or to effect similar
          compliance under any state laws.  Notwithstanding anything herein to
          the contrary, the Company shall not be obligated to cause to be issued
          or delivered any certificates evidencing shares of Common Stock
          pursuant to the Plan unless and until the Company is advised by its
          counsel that the issuance and delivery of such certificates is in
          compliance with all applicable laws, regulations of governmental
          authority and the requirements of any securities exchange on which
          shares of Common Stock are traded.  The Committee may require, as a
          condition of the issuance and delivery of certificates evidencing
          shares of Common Stock pursuant to the terms hereof and of the
          applicable Award Agreement, that the recipient of such shares make
          such covenants, agreements and representations, and that such
          certificates bear such legends, as the Committee, in its sole
          discretion, deems necessary or desirable.

     (b)  The transfer of any shares of Common Stock hereunder shall be
          effective only at such time as counsel to the Company shall have
          determined that the issuance and delivery of such shares is in
          compliance with all applicable laws, regulations of governmental
          authority and the requirements of any securities exchange on which
          shares of Common Stock are traded. The Committee may, in its sole
          discretion, defer the effectiveness of any transfer of shares of
          Common Stock hereunder in order to allow the issuance of such shares
          to be made


                                       17
<PAGE>

          pursuant to registration or an exemption from registration or other
          methods for compliance available under federal or state securities
          laws.  The Committee shall inform the Participant in writing of its
          decision to defer the effectiveness of a transfer. During the period
          of such deferral in connection with the exercise of an Option, the
          Participant may, by written notice, withdraw such exercise and obtain
          the refund of any amount paid with respect thereto.

16.  WITHHOLDING TAXES.

     Whenever cash is to be paid pursuant to an Incentive Award, the Company
shall have the right to deduct therefrom an amount sufficient to satisfy any
federal, state and local withholding tax requirements related thereto.  Whenever
shares of Common Stock are to be delivered pursuant to an Incentive Award, the
Company shall have the right to require the Participant to remit to the Company
in cash an amount sufficient to satisfy any federal, state and local withholding
tax requirements related thereto.  With the approval of the Committee, a
Participant may satisfy the foregoing requirement by electing to have the
Company withhold from delivery shares of Common Stock having a fair market value
equal to the amount of tax to be withheld.  Such shares shall be valued at their
Fair Market Value on the date on which the amount of tax to be withheld is
determined (the "TAX DATE").  Fractional share amounts shall be settled in cash.
Such a withholding election may be made with respect to all or any portion of
the shares to be delivered pursuant to an Incentive Award.

17.  NOTIFICATION OF ELECTION UNDER SECTION 83(B) OF THE CODE.

     If any Participant shall, in connection with the acquisition of shares of
Common Stock under the Plan, make the election permitted under Section 83(b) of
the Code (i.e., an election to include in gross income in the year of transfer
the amounts specified in Section 83(b)), such Participant shall notify the
Company in writing of such election within 10 days of filing notice of the
election with the Internal Revenue Service, in addition to any filing and a
notification required pursuant to regulation issued under the authority of Code
Section 83(b).

18.  NOTIFICATION UPON DISQUALIFYING DISPOSITION UNDER SECTION 421(B) OF THE
     CODE.

     Each Award Agreement with respect to an Incentive Stock Option shall
require the Participant to notify the Company in writing of any disposition of
shares of Common Stock issued pursuant to the exercise of such Option under the
circumstances described in Section 421(b) of the Code (relating to certain
disqualifying dispositions), within 10 days of such disposition.

19.  AMENDMENT OR TERMINATION OF THE PLAN.

     The Board of Directors may, at any time, suspend or terminate the Plan or
revise or amend it in any respect whatsoever; provided, however, that
stockholder approval shall be required if and to the extent the Board of
Directors determines that such approval is appropriate for purposes of
satisfying Section 162(m) or 422 of the Code or to the extent such approval is
required by the rules of any stock exchange on which the Common Stock is listed.
Nothing herein shall restrict the Committee's ability to exercise its
discretionary authority pursuant to Section 4 of the Plan, which discretion may
be exercised without amendment to the


                                       18
<PAGE>

Plan.  No action hereunder may, without the consent of a Participant, reduce
the Participant's rights under any outstanding Incentive Award.

20.  TRANSFERS UPON DEATH; NONASSIGNABILITY.

     Upon the death of a Participant, outstanding Incentive Awards granted to
such Participant may be exercised only by the executor or administrator of the
Participant's estate or by a person who shall have acquired the right to such
exercise by will or by the laws of descent and distribution.  No transfer of an
Incentive Award by will or the laws of descent and distribution shall be
effective to bind the Company unless the Committee shall have been furnished
with (a) written notice thereof and with a copy of the will and/or such evidence
as the Committee may deem necessary to establish the validity of the transfer
and (b) an agreement by the transferee to comply with all the terms and
conditions of the Incentive Award that are or would have been applicable to the
Participant and to be bound by the acknowledgments made by the Participant in
connection with the grant of the Incentive Award.

     During a Participant's lifetime, the Committee may permit the transfer,
assignment or other encumbrance of an outstanding Option or outstanding shares
of Restricted Stock unless such Option is an Incentive Stock Option and the
Committee and the Participant intend that it shall retain such status.
Notwithstanding the foregoing, subject to any conditions as the Committee may
prescribe, a Participant may, upon providing written notice to the secretary of
the Company, elect to transfer any or all Options granted to such Participant
pursuant to the Plan to members of his or her immediate family, including, but
not limited to, children, grandchildren and spouse or to trusts for the benefit
of such immediate family members or to partnerships in which such family members
are the only partners; provided, however, that no such transfer by any
Participant may be made in exchange for consideration.

21.  EXPENSES AND RECEIPTS.

     The expenses of the Plan shall be paid by the Company.  Any proceeds
received by the Company in connection with any Incentive Award will be used for
general corporate purposes.

22.  FAILURE TO COMPLY.

     In addition to the remedies of the Company elsewhere provided for herein,
failure by a Participant (or beneficiary or transferee) to comply with any of
the terms and conditions of the Plan or the applicable Award Agreement, unless
such failure is remedied by such Participant (or beneficiary or transferee)
within ten days after notice of such failure by the Committee, shall be grounds
for the cancellation and forfeiture of such Incentive Award, in whole or in
part, as the Committee, in its absolute discretion, may determine.

23.  EFFECTIVE DATE AND TERM OF PLAN.

     The Plan became effective on the Effective Date, but the Plan (and any
grants of Incentive Awards made prior to stockholder approval of the Plan) shall
be subject to the requisite approval of the stockholders of the Company.  In the
absence of such approval, such Incentive Awards shall be null and void.  Unless
earlier terminated by the Board of Directors, the right to grant Incentive
Awards under the Plan will terminate on the tenth anniversary of the Effective
Date.  Incentive Awards outstanding at Plan termination will remain in effect
according to their terms and the provisions of the Plan.

24.  APPLICABLE LAW.

     Except to the extent preempted by any applicable federal law, the Plan will
be construed and administered in accordance with the laws of the State of Utah,
without reference to the principles of conflicts of law.

25.  PARTICIPANT RIGHTS.

     No Participant shall have any claim to be granted any Incentive Award under
the Plan, and there is no obligation for uniformity of treatment for
Participants.  Except as provided specifically herein, a Participant or a
transferee of an Incentive Award shall have no rights as a stockholder with
respect to any shares covered by any award until the date of the issuance of a
Common Stock certificate to him for such shares.

26.  UNFUNDED STATUS OF AWARDS.

     The Plan is intended to constitute an "unfunded" plan for incentive and
deferred compensation.  With respect to any payments not yet made to a
Participant pursuant to an Incentive Award, nothing contained in the Plan or any
Award Agreement shall give any such Participant any rights that are greater than
those of a general creditor of the Company.

27.  NO FRACTIONAL SHARES.

     No fractional shares of Common Stock shall be issued or delivered pursuant
to the Plan.  The Committee shall determine whether cash, other Incentive
Awards, or other property shall be issued or paid in lieu of such fractional
shares or whether such fractional shares or any rights thereto shall be
forfeited or otherwise eliminated.

28.  BENEFICIARY.

     A Participant may file with the Committee a written designation of a
beneficiary on such form as may be prescribed by the Committee and may, from
time to time, amend or revoke such designation.  If no designated beneficiary
survives the Participant, the executor or administrator of the Participant's
estate shall be deemed to be the Participant's beneficiary.

29.  INTERPRETATION.

     The Plan is designed and intended to comply with Rule 16b-3 promulgated
under the Exchange Act and, with Section 162(m) and 422 of the Code, and all
provisions hereof shall be construed in a manner to so comply.
