         1. Purpose and Scope of the Plan. The purpose of this  incentive  stock
plan is to attract  and  retain the best  available  non-officer  personnel  for

confer  upon any  Participant  any right  with  respect  to  continuation  of an
employment or consulting  relationship with the Company,  nor shall it interfere
in any way with an  employee's  right or the  Company's  right to terminate  the
employment or consulting relationship at any time.

         Directors to  administer  the Plan on behalf of the Board of Directors,
         subject  to such terms and  conditions  as the Board of  Directors  may
         prescribe.  Once appointed, the committee shall continue to serve until
         otherwise  directed  by the Board of  Directors.  From time to time the
         Board of Directors  may increase the size of the  Committee and appoint
         additional  members  of the  Board,  remove  members  (with or  without
         cause),  appoint new members,  fill vacancies however caused, or remove
         all members of the Committee and  thereafter  directly  administer  the
         Plan.

                  (b) Powers of the  Board.  Subject  to the  provisions  of the
         Plan, the Board shall have the  authority,  in its  discretion:  (i) to
         grant Incentive Stock Options,  Nonstatutory Stock Options,  Restricted
         Stock Awards,  Reload Options  concurrently with the grant of any Award
         of Incentive Stock Options or Nonstatutory  Stock Options,  Other Stock
         Based Awards,  and Other  Benefits;  (ii) to determine,  upon review of
         relevant  information  and in accordance with Section 2(1) of the Plan,
         the Fair  Market  Value of the Common  Stock;  (iii) to  determine  the
         exercise price per share of Options to be granted, which exercise price
         shall be determined in accordance  with Section 8(a) of the Plan;  (iv)
         to determine  the Employees and  Consultants  to whom,  and the time or
         times at which,  Awards shall be granted and the number of shares to be
         represented  by  each  Award;  (v)  to  interpret  the  Plan;  (vi)  to
         prescribe,  amend,  and rescind rules and  regulations  relating to the
         Plan; (vii) to determine the terms and provisions of each Award granted
         (which need not be  identical)  and,  with the consent of the holder of
         the Award,  modify or amend each Award;  (viii) to  accelerate or defer
         (with the consent of the  Participant)  the exercise or vesting date of
         any Award,  consistent  with the  provisions  of Section 7 of the Plan;
         (ix) to  authorize  any person to execute on behalf of the  Company any
         instrument  required  to  effectuate  the grant of an Award  previously
         granted by the Board; and (x) to make all other  determinations  deemed
         necessary or advisable for the administration of the Plan.

                  (c)      Effect   of   Board's   Decision.    All   decisions,
         determinations,  and interpretations of the  Board  shall  be final and
         binding on all Participants and any other holders of any Awards granted
         under the Plan.

         5.       Eligibility.

                  (a)  Generally.  Awards may be granted only to  Employees  and
         Consultants.  Incentive Stock Options may be granted only to Employees.
         An Employee or  Consultant  who has been granted an Award may, if he is
         otherwise eligible, be granted an additional Award or Awards.

                  (b) Limitations on Incentive Stock Options. The aggregate Fair
         Market Value  (determined as of the date of grant) of Common Stock with
         respect to which  Incentive Stock Options are exercisable for the first
         time by any  Participant  during any calendar  year (under all plans of
         the Company,  Parent, or any Subsidiary) shall not exceed $100,000.  If
         the Fair Market  Value  (determined  as of the date of grant) of Common
         Stock with respect to which Incentive Stock Options are exercisable for
         the first time by any  Participant  during any  calendar  year  exceeds
         $100,000, then the Options for the first $100,000 worth of Common Stock
         to become  exercisable  in such calendar year shall be Incentive  Stock
         Options  and the  Options  for the  amount in excess of  $100,000  that
         become  exercisable in that calendar year shall be  Nonstatutory  Stock
         Options.  In the  event  that the Code or the  regulations  promulgated
         thereunder  are  amended  after the date of the Plan to  provide  for a
         different  limit on the Fair Market Value of Common Stock  permitted to
         be subject to Incentive  Stock Options,  such different  limit shall be
         automatically  incorporated in this Section 5(b) and shall apply to any
         Incentive  Stock  Options  granted  after  the  effective  date of such
         amendment.

                  (c) Other Stock Based  Awards.  The Board shall have the right
         to  grant  Other  Stock  Based  Awards   which  may  include,   without
         limitation,  the grant of Common  Stock  based on  certain  conditions,
         including short-term incentives or the issuance of Common Stock in lieu
         of cash under other incentive or deferred  compensation programs of the
         Company.

                  (d)      Other  Benefits.  The Board  shall  have the right to
         provide  Other  Benefits,  if the Board believes that such Awards would
         further the purposes for which this Plan was established.

         6.       Term of Plan.  The Plan shall  become effective upon  adoption
by the Board of  Directors.  It shall continue in effect until terminated  under
Section 14  of the Plan.  No Awards of Incentive  Stock  Options  shall  be made
hereunder after December 17, 2008.

         7. Term of Awards. The term of each Incentive Stock Option shall be ten
(10) years from the date of grant or such shorter term as may be provided in any
notice or agreement evidencing such Award; provided,  however, in the case of an
Incentive  Stock Option granted to a Participant  who, at the time the Incentive
Stock Option is granted,  owns stock representing more than ten percent (10%) of
the  voting  power of all  classes  of stock of the  Company  or any  Parent  or
Subsidiary,  the term of the Incentive Stock Option shall be five (5) years from
the date of grant or such shorter time as may be provided in the Incentive Stock
Option  agreement.  The foregoing  notwithstanding,  if the Code or  regulations
promulgated  thereunder  are  subsequently  amended to provide  for a  different
percentage of voting power or maximum  option term for Incentive  Stock Options,
such new limits shall be automatically  incorporated in this Section 7 and shall
apply to any Incentive  Stock Options  granted after the effective  date of such
amendment. The term of each Reload Option shall be equal to the remaining option
term of the underlying  Option.  The term of each Award, if applicable,  that is
not an Incentive  Stock Option or Reload Option shall be determined by the Board
and set forth in the agreement or notification  relating to  Nonstatutory  Stock
Options, Restricted Stock, Other Stock Based Awards, or Other Benefits.

         8.       Exercise Price and Consideration.

                  (a)      Exercise  Price.  The  per  Share exercise  price for
         the Shares to be issued pursuant to exercise of an Option shall be such
         price  as is  determined  by  the  Board,  but  shall be subject to the
         following:

                           (i) In the case of an  Incentive  Stock  Option,  any
                  restrictions  imposed by the Code at the time of grant,  which
                  restrictions currently are as follows:

                                    (A) grants to an  Employee  who, at the time
                           of the grant of such  Incentive  Stock  Option,  owns
                           stock representing more than ten percent (10%) of the
                           voting  power of all  classes of stock of the Company
                           or any Parent or  Subsidiary,  shall have a per Share
                           exercise  price no less than 110% of the Fair  Market
                           Value per Share on the date of grant; or

                                    (B) grants to any other  Employee shall have
                           a per Share  exercise  price no less than 100% of the
                           Fair Market Value per Share on the date of grant.

                           (ii)     In the case of Nonstatutory  Stock  Options,
                  at any price per Share  determined by the Board.

                           (iii) In the case of Reload Options, unless otherwise
                  established  by the  Board,  the  exercise  price per share of
                  Common Stock  deliverable upon the exercise of a Reload Option
                  shall be the Fair Market  Value of a share of Common  Stock on
                  the date the grant of the Reload Option becomes effective.

                  (b)  Consideration  for  Restricted  Stock,  Other Stock Based
         Awards,  and Other Benefits.  In the case of Restricted Stock, an award
         of  Restricted  Stock may provide that the  Participant  be required to
         furnish such  consideration for the Award as the Board shall determine,
         or may  be  issued  in  exchange  for  past  services  or  other  legal
         consideration.  An Award of  Restricted  Stock  may  provide  that such
         Restricted  Stock may be  exchanged  during the  Restricted  Period for
         other  Restricted Stock upon such terms and conditions as the Board may
         permit or shall  require.  Payment  under or a settlement  of any Other
         Stock Based Awards and Other  Benefits shall be made in such manner and
         at such times as the Board may determine.

                  (c) Form of  Consideration.  The  consideration to be paid for
         the  Shares  to be  issued  upon  exercise  of an Option or grant of an
         Award,  including  the method of payment,  shall be  determined  by the
         Board and may  consist  entirely of (i) cash,  (ii) check,  (iii) other
         Shares  of  Common  Stock  having  a Fair  Market  Value on the date of
         surrender  equal to the  aggregate  exercise  price of the Shares as to
         which the Option shall be exercised,  (iv) vested and exercisable  (but
         unexercised)  Options  valued at the  difference  between the  exercise
         price and Fair Market Value of the Shares,  or (v) any  combination  of
         such methods of payment,  or other  consideration and method of payment
         for the  issuance  of Shares to the extent  permitted  under the Nevada
         General  Corporation Law. In making its determination as to the type of
         consideration to accept, the Board shall consider whether acceptance of
         the consideration may be reasonably expected to benefit the Company.

         9.       Exercise of Option.

                  (a)  Generally.  Any  Option  granted  under the Plan shall be
         exercisable  at such times and under such  conditions  as determined by
         the Board,  including  performance criteria with respect to the Company
         and/or the Participant,  and as shall be permissible under the terms of
         the Plan.  An Option may not be  exercised  for a fraction  of a Share.
         Anything to the contrary  notwithstanding,  each Reload Option is fully
         exercisable  two years  from the  effective  date of grant (or if fewer
         than two years remain  until the  termination  of this Plan,  then such
         Reload Option shall be exercisable  within 90 days prior to termination
         of the Plan).

                  (b) Procedure.  An Option shall be deemed to be exercised when
         written  notice of exercise in  accordance  with Section  22(c) and (d)
         hereof (if  applicable,  in the form  required by the  Nonstatutory  or
         Incentive  Stock  Option  agreement  or  notice)  has been given to the
         Company  in  accordance  with the  terms of the  Option  by the  person
         entitled  to exercise  the Option and full  payment for the Shares with
         respect  to which the  Option is  exercised  has been  received  by the
         Company.  Full payment may, as authorized by the Board,  consist of any
         consideration  and method of payment  allowable  under Section 8 of the
         Plan.  The  Company  shall  issue  (or  cause to be  issued)  the stock
         certificate promptly upon exercise of the Option. No adjustment will be
         made for a dividend  or other  right for which the record date is prior
         to the date the stock  certificate  is issued,  except as  provided  in
         Section  12 of the Plan.  Exercise  of an Option  in any  manner  shall
         result in a decrease  in the number of Shares  which may be  available,
         both for purposes of the Plan and for purchase under the Option, by the
         number of Shares as to which the Option is exercised.

         10.      Conditions and Restrictions Affecting Awards.

         (a)      Certain Events Affecting Exercisability  of Incentive
                  Stock Options.

                           (i)  Termination  of  Status  as  an  Employee.  With
                  respect to Options  that are  Incentive  Stock  Options at the
                  time of grant,  in the event of termination of a Participant's
                  Continuous  Status as an Employee,  such  Participant may, but
                  only within three (3) months  after such event of  termination
                  of a Participant's Continuous Status as an Employee (but in no
                  event  later  than the date of  expiration  of the term of the
                  Incentive  Stock  Option  as set forth in  Section 7  hereof),
                  exercise his Incentive  Stock Option to the extent that he was
                  entitled  to exercise  it at the date of  termination.  To the
                  extent  that he was not  entitled to  exercise  the  Incentive
                  Stock  Option at the date of such  termination,  or if he does
                  not exercise the Incentive Stock Option (which he was entitled
                  to  exercise)  within the time  specified  in this  Subsection
                  10(a) the Incentive Stock Option shall terminate.

                           (ii)  Disability  of  Participant.  With  respect  to
                  Options that are Incentive Stock Options at the time of grant,
                  notwithstanding  the provision of Section  10(a)(i)  above, in
                  the event of termination of a Participant's  Continuous Status
                  as  an  Employee  as a  result  of  his  total  and  permanent
                  disability  (as defined in Section  22(e)(3) of the Code),  he
                  may, but only within twelve (12) months  following the date of
                  termination (but in no event later than the date of expiration
                  of the term of the  Incentive  Stock  Option  as set  forth in
                  Section 7 hereof),  exercise his Incentive Stock Option to the
                  extent  he  was  entitled  to  exercise  it  at  the  date  of
                  termination.  To the  extent  that  he  was  not  entitled  to
                  exercise   the   Incentive   Stock   Option  at  the  date  of
                  termination,  or if he does not exercise the  Incentive  Stock
                  Option  (which he was  entitled to  exercise)  within the time
                  specified herein, the Incentive Stock Option shall terminate.

                           (iii) Death of  Participant.  With respect to Options
                  that are Incentive  Stock Options at the time of grant, in the
                  event of the death of a Participant:

                                    (A)  who is at the  time  of  his  death  an
                           Employee  of the  Company  and who shall have been in
                           Continuous  Status as an  Employee  since the date of
                           grant of the Incentive  Stock  Option,  the Incentive
                           Stock  Option may be  exercised,  at any time  within
                           twelve (12) months  following  the date of death (but
                           in no event later than the date of  expiration of the
                           term of the  Incentive  Stock  Option as set forth in
                           Section 7 hereof), by the Participant's  estate or by
                           a person  who  acquired  the  right to  exercise  the
                           Incentive Stock Option by bequest or inheritance, but
                           only to the extent that the Participant had the right
                           to exercise the Incentive Stock Option at the date of
                           death; or

                                    (B) which  occurs  within  three (3)  months
                           after  the  termination  of  Continuous  Status as an
                           Employee,   the   Incentive   Stock   Option  may  be
                           exercised,  at any time  within  twelve  (12)  months
                           following  the date of death  (but in no event  later
                           than  the  date  of  expiration  of the  term  of the
                           Incentive   Stock  Option  as  set  forth  Section  7
                           hereof),  by the Participant's  estate or by a person
                           who or entity  which  acquired  the right to exercise
                           the Incentive Stock Option by bequest or inheritance,
                           but only to the extent of the right to exercise  that
                           had accrued at the date of termination.

                           (iv) Expiration of Option Period. Subject to Sections
                  7  and  10,  notwithstanding  anything  in  the  Plan  to  the
                  contrary,  all  Incentive  Stock  Options  to the  extent  not
                  already  exercised  shall  terminate upon expiration of a term
                  equal to ten (10) years from the date of grant.

                  (b)      Certain Conditions Affecting Restricted Stock Awards.

                           (i)  Restriction.   Except  as  provided  in  Section
                  10(b)(iii),  at the time of an Award of Restricted  Stock, the
                  Board may establish in its discretion,  for each Participant a
                  vesting  schedule and a period of time  ("Restricted  Period")
                  during  which  Restricted  Stock  may not be  sold,  assigned,
                  transferred,  pledged,  or  otherwise  encumbered,  except  as
                  hereinafter  provided.  Except for such restrictions as may be
                  provided  in the  Restricted  Stock  agreement  or notice  and
                  subject to this Subsection  10(b), the Participant  shall have
                  all rights of a  stockholder  with respect to such  Restricted
                  Stock.  The Board, in its discretion,  may accelerate the time
                  at  which  any or all of the  restrictions  shall  lapse  with
                  respect  to  any  shares  of  Restricted  Stock  prior  to the
                  expiration  of the  Restricted  Period or remove any or all of
                  such restrictions, as it deems appropriate.

                           (ii) Registration and Redelivery of Restricted Stock.
                  Each  certificate  of Restricted  Stock shall be registered in
                  the name of the Participant and deposited by the  Participant,
                  together  with a stock  power  endorsed  in  blank,  with  the
                  Company.  During the Restricted  Period,  the Restricted Stock
                  shall remain in the  possession of the Company.  At the end of
                  the  Restricted  Period,  the Company  shall  redeliver to the
                  Participant  (or the  Participant's  legal  representative  or
                  personal  representative)  the  certificates  of Common  Stock
                  deposited  pursuant to this Subsection  10(b)(ii).  The Common
                  Stock so  delivered  to the  Participant  shall no  longer  be
                  subject to the provisions of this Subsection 10(b).

                           (iii)   Termination   of   Employment.   Unless   the
                  Restricted  Stock agreement or notice otherwise  provides,  in
                  the event the Participant's employment with the Company and/or
                  its  Subsidiaries  or Parent is  terminated  for reasons other
                  than  death,  total and  permanent  disability  (as defined in
                  Section  22(e)(3) of the Code), or retirement after the age of
                  65, all Restricted Stock awarded to such Participant  which is
                  still  subject  to  restriction  shall be  forfeited.  For the
                  purposes of this Subsection 10(b)(iii),  the forfeiture period
                  for  each  Award  of  Restricted  Stock  shall  be  separately
                  calculated  from the date of the Award.  Unless the Restricted
                  Stock agreement or notice otherwise provides, the restrictions
                  contained  in  Subsection  10(b)(i)  shall  terminate  on  the
                  Participant's   death,  total  and  permanent  disability  (as
                  defined in Section 22(e)(3) of the Code), or attainment of age
                  sixty-five (65).

                  (c)      Certain Conditions Affecting Reload Options.

                           (i)      Non-Qualification as Incentive Stock Option.
                  Notwithstanding  the fact that the  underlying  Option  may be
                  an Incentive  Stock  Option,  a Reload  Option is not intended
                  to qualify as an Incentive Stock Option.

                           (ii) Reload Option  Amendment.  Each Incentive  Stock
                  Option and Nonstatutory Stock Option agreement or notice shall
                  state  whether the Board has  authorized  Reload  Options with
                  respect to the  underlying  options.  Upon the  exercise of an
                  underlying  option,  any  additional  Reload  Option  must  be
                  evidenced  by an  amendment  to the  underlying  agreement  or
                  notice or by a new notice from the Board.

                           (iii) Termination of Employment. No additional Reload
                  Options  shall be granted to  Participants  when  Options  are
                  exercised  pursuant  to  the  terms  of  this  Plan  following
                  termination of the Participant's employment.

                           (iv) Application Sections. Applicable sections of the
                  Plan or written  notice or agreement  regarding  the manner of
                  payment,  restrictions,  death, retirement, total or permanent
                  disability (as defined in Section 22(e)(3) of the Code) of the
                  Participant, and similar provisions relating to the underlying
                  Option, are incorporated by reference in this Subsection 10(c)
                  as though fully set forth herein.

                  (d) Certain Conditions  Affecting Other Stock Based Awards and
         Other  Benefits.  Unless the agreement or notice  relating to the Other
         Stock Based Awards or Other Benefits otherwise provides,  except in the
         event of the  Participant's  death,  total or permanent  disability (as
         defined in Section 22(e)(3) of the Code), or retirement after attaining
         age 65, in the event that the  Participant  terminates  employment with
         the  Company  and/or  its  Subsidiaries  or  Parent  prior  to the time
         benefits become payable  pursuant to Awards of Other Stock Based Awards
         or Other Benefits,  such Awards shall be immediately forfeited.  Unless
         the  agreement  or notice  relating to the Other Stock Based  Awards or
         Other Benefits  otherwise  provides,  in the event of the Participant's
         death, total or permanent disability (as defined in Section 22(e)(3) of
         the Code), or retirement  after attaining age 65, the Company shall pay
         to the  Participant  (or  the  Participant's  legal  representative  or
         personal representative) the amount that would have been payable to the
         Participant  had  the  Participant  satisfied  all of the  requirements
         contained in the agreement  relating to such Award calculated as of the
         date of the occurrence of an event described in this sentence.

                  (e)      Special Conditions  Concerning  Forfeiture,  Right to
         Repurchase,  and Economic Benefit.    Unless approved in writing by the
         Board or otherwise provided  in the  agreement reflecting the Award, if

                           (i)  the  Participant   (A)  voluntarily   terminates
                  employment with the Company or the Participant's employment is
                  involuntarily  terminated for nonperformance of duties and (B)
                  within one year of either such  termination  of employment the
                  Participant   becomes,   directly   or   indirectly,   a  sole
                  proprietor, partner, stockholder, officer, director, employee,
                  independent  contractor,   source  of  business  or  financial
                  resources,  or  consultant of or to any  competitive  business
                  which is related to the  contract or common  carriage of goods
                  (such  determination  being  made  by the  Board  in its  sole
                  discretion); or

                           (ii) the  Participant's  employment is  involuntarily
                  terminated  for (or  the  Participant  voluntarily  terminates
                  because of) gross misconduct,  fraud, embezzlement,  theft, or
                  breach of any fiduciary duty to the Company

                  (each of (i) and (ii) a "Triggering  Event"),  then the Award,
                  regardless of whether then vested, shall immediately terminate
                  and be forfeited to the Company.  With respect to Options, the
                  Board, in its discretion,  may cause the Company to repurchase
                  each Share  issued in respect of an  exercised  Option for the
                  exercise  price of such  Option and the  Participant  shall be
                  required  to convey such Shares to the Company for such price.
                  With respect to any non-Option  Award,  if a Triggering  Event
                  occurs, the Participant shall be required to return any Shares
                  received by such person in an Award to the Company immediately
                  upon demand by the Board. If a Triggering Event occurs and the
                  Participant has already disposed of all or some of the Shares,
                  the Board may  demand,  and the  Participant  shall pay to the
                  Company,  (i) with respect to Options,  the difference between
                  the  exercise  price and the Fair Market  Value on the date of
                  exercise,  or (ii) with respect to any other  Award,  the Fair
                  Market  Value of the Award on the date it was  received by the
                  Participant.  The Company shall exercise its rights  hereunder
                  by written  notification to the Participant to be given within
                  180 days  after  the  Board  becomes  aware of the  Triggering
                  Event.

         11.  Transferability  of  Options.   Except  with  Board  approval  and
otherwise in accordance with applicable provisions of the Code and SEC rules and
regulations,  all Awards may not be transferred in any manner other than by will
or by the laws of  descent  or  distribution  and may be  exercised,  during the
lifetime of the Participant,  only by the Participant.  Following transfer,  the
Awards  shall  continue to be subject to the same terms and  conditions  as were
applicable  immediately prior to transfer,  provided that the term "Participant"
shall be deemed to refer to the transferee.

         12. Adjustments Upon Certain Changes. In the event of any change in the
outstanding   Common  Stock  by  reason  of  a  stock  split,   stock  dividend,
combination,  reclassification,  or exchange of Common Stock,  recapitalization,
merger,  consolidation,  or other  similar  event,  the  shares of Common  Stock
authorized   hereunder  and  outstanding   Awards,   as  applicable,   shall  be
proportionately  adjusted  by the  Board  in its  sole  discretion  and any such
judgment shall be binding and conclusive on all persons.  Provided,  however, in
the case of Incentive  Stock Options,  no such  adjustment  shall be made if the
result  thereof would be that the excess of (i) the aggregate  Fair Market Value
of the new or substituted  shares over (ii) the aggregate exercise price of such
shares is more than (x) the excess of the  aggregate  Fair  Market  Value of all
shares subject to the Option immediately before such substitutions or assumption
over (y) the aggregate  exercise price of such shares, or that the new Option or
the assumption of the old Option gives the Participant additional benefits which
the Participant did not have under the old Option.

         13. Time of  Granting  Awards.  The date of grant of an Award,  for all
purposes,  shall be the date on which the Board makes the determination granting
that Award or such other effective date as the Board may specify in its grant of
the  Award.  Notice  of the  determination  shall be given to each  Employee  or
Consultant  to whom an Award is so granted  within a  reasonable  time after the
date of such grant and such notice or the Award  agreement shall be effective as
of the date of the grant.






         14.      Amendment and Termination of the Plan.

                  (a)  Amendment  and  Termination.   The  Board  may  amend  or
         terminate  the Plan from time to time in such respects as the Board may
         deem advisable, unless otherwise required by any applicable laws.

                  (b) Effect of  Amendment  or  Termination.  Any  amendment  or
         termination  of the Plan shall not affect  Awards  already  granted and
         those  Awards shall remain in full force and effect as if this Plan had
         not been  amended  or  terminated,  unless  mutually  agreed  otherwise
         between  the  Participant  and the Board,  which  agreement  must be in
         writing and signed by the Participant and the Company.

         15.  Conditions  Upon  Issuance of Shares.  Shares  shall not be issued
pursuant to the  exercise or grant of an Award  unless the  exercise or grant of
such  Award and the  issuance  and  delivery  of Shares  shall  comply  with all
relevant  provisions of law, including,  without limitation,  the Securities Act
and the Exchange Act, the rules and regulations promulgated thereunder,  and the
requirements of any stock exchange or quotation system upon which the Shares may
then be listed,  and shall be further subject to the approval of counsel for the
Company  with  respect  to such  compliance.  The Board may  require  any person
receiving  Common Stock hereunder to acknowledge that such Common Stock is being
acquired for investment  purposes and not with a view for resale or distribution
and such Common Stock shall not be sold or transferred unless in accordance with
applicable  law and  regulations.  If the  Company,  as part of an  offering  of
securities  or  otherwise,  finds it  desirable  because of legal or  regulatory
requirements  to reduce the period during which  Options may be  exercised,  the
Board may, in its  discretion and without the holders'  consent,  so reduce such
period  on not less than  fifteen  (15)  days'  written  notice  to the  holders
thereof.

         16. Reservation of Shares.  The Company,  during the term of this Plan,
shall at all times  reserve and keep  available the number of Shares as shall be
sufficient to satisfy the requirements of the Plan. The inability of the Company
to  obtain  authority  from  any  regulatory  body  having  jurisdiction,  which
authority  is deemed by the  Company's  counsel  to be  necessary  to the lawful
issuance or sale of any Shares under the Plan,  shall relieve the Company of any
liability  in respect of the failure to issue or sell the Shares as to which the
requisite authority shall not have been obtained.

         17.      Award   Agreement.  Awards  shall  be   evidenced  by  written
agreements  or notices in form as the Board shall approve.

         18.      Tax Withholding.

               (a) The Board  shall have sole  discretion  whether  to  withhold
         stock  sufficient  to  satisfy  any  withholding  or other tax due with
         respect the exercise of an Option,  the vesting of Restricted Stock, or
         any similar  transaction  under the Plan,  or to demand such amounts in
         cash.  Any tax  withholding  effected  in shares of Common  Stock  must
         comply with all applicable laws.

               (b)  Notwithstanding  anything in the Plan to the  contrary,  the
         Participant  acknowledges that under certain  circumstances,  including
         but not limited to a "disqualifying  disposition" of an Incentive Stock
         Option  under  Section  422(a)(i)  of the  Code,  the  Participant  may
         recognize  ordinary  income  which,  for tax  purposes,  is  considered
         payment  of wages for  services.  As a  result,  the  Company  may have
         certain tax  withholding and reporting  obligations.  The Company shall
         not be  obligated to issue any stock  certificate  upon the exercise of
         the right to purchase, or the transfer of, Shares until the Participant
         has delivered  sufficient  funds to cover all income,  FICA,  FUTA, and
         other  applicable tax  withholding.  The  Participant  shall notify the
         Company  of any  disqualifying  disposition  of Shares  underlying  the
         Option  (currently,  any  disposition  within  two years of the date of
         grant or one year of the exercise date or cashless exercise with shares
         underlying  the  Option  tendered  in  payment)  and take  all  actions
         necessary  for the Company to obtain a tax  deduction  if  compensation
         income is  deemed  to result  from any  exercise  or  disposition.  The
         Participant  shall indemnify and hold the Company  harmless against any
         loss it may  experience  as a result of the  Participant's  failure  to
         comply with this subsection. At the Board's sole discretion, to satisfy
         the  Company's  withholding  obligations,  the  Company may retain such
         number of shares of Common Stock subject to the exercised  Option which
         have an aggregate  Fair Market  Value on the date of exercise  equal to
         the  Company's  aggregate  federal,   state,  local,  and  foreign  tax
         withholding  obligations  as a result of the  exercise of the Option by
         the Participant. The Board may consider the Participant's preference in
         making such  determination,  but the Participant  acknowledges that the
         Board  is  under  no   obligation   to  follow  or  even  consider  the
         Participant's preference.

         19. Non-Uniform Determinations.  The Board's determinations,  including
without limitation, (a) the Participants' right to receive Awards, (b) the form,
amount,  and timing of Awards,  (c) the terms,  conditions,  and  provisions  of
Awards (including vesting and forfeiture provisions),  and (d) the agreements or
notices  evidencing  the  same,  need  not be  uniform  and  may be  made  by it
selectively  among  Participants  who  receive,  or who are eligible to receive,
Awards under the Plan, whether or not such Participants are similarly situated.

         20.  Indemnification.  Directors shall be indemnified and held harmless
by the Company from any loss, liability,  or expense that may be imposed upon or
incurred by such present or past Director in connection  with or resulting  from
any claim,  action, or proceeding in which the Director is involved by reason of
any action taken or failure to act under the Plan;  provided such Director shall
give the Company an  opportunity,  at its own expense,  to defend the same.  The
foregoing right of indemnification shall not be exclusive of any other rights of
indemnification  to which  such  persons  may be  entitled  under the  Company's
Articles of  Incorporation or Bylaws,  as a matter or law, or otherwise,  or any
power that the Company may have to indemnify them or hold them harmless.

         21.      Requirements  of Law.  Awards,  agreements,  notices,  and the
issuance of shares of Common Stock shall be  subject to applicable laws,  rules,
and  regulations,  and  to  such  approvals  by  any  governmental  agencies  or
securities exchanges or quotation systems as may be required.

         22.      Miscellaneous.

                  (a) Participant Not a Stockholder.  The Participant  shall not
         be deemed for any  purposes to be a  stockholder  of the  Company  with
         respect to an Award except to the extent that a stock  certificate  has
         been issued (as evidenced by the appropriate  entry on the books of the
         Company) or of a duly authorized  transfer agent of the Company and, if
         applicable, the Option exercised and payment made.

                  (b) Disputes or  Disagreements.  The Participant  agrees,  for
         himself  and  his  personal  representatives,   that  any  disputes  or
         disagreements  which  arise  under or as a result  of this  Plan or any
         agreement  hereunder  shall  be  determined  by the  Board  in its sole
         discretion,  and any  interpretation  by the Board of the terms of this
         Plan or any Agreement shall be final, binding, and conclusive.

                  (c) Notices. Any notice to be given hereunder ("Notice") shall
         be addressed to the Company in care of its  Treasurer at 5175 West 2100
         South,  West Valley City,  Utah 84120 or at its then current  corporate
         headquarters.  Notice to be given to the Participant shall be addressed
         to him  or  her  by  hand  delivery  or at  his  or  her  then  current
         residential  address as appearing on the payroll records.  Notice shall
         be deemed duly given when  enclosed in a properly  sealed  envelope and
         deposited by certified mail, return receipt requested, in a post office
         or  branch  post  office  regularly  maintained  by the  United  States
         Government.

                  (d) Exercise of Incentive  Stock Option.  Subject to the terms
         and  conditions of the Plan and any agreement  reflecting  the grant of
         Incentive Stock Option, such Option may be exercised only by completing
         and signing a written notice in substantially the following form:

                  I hereby  exercise  [all/part of] the  Incentive  Stock Option
                  granted  to  me  by  Simon  Transportation  Services  Inc.  on
                  ____________   (date  of   grant),   and  elect  to   purchase
                  ____________  (______)  shares of the Company's Class A Common
                  Stock for  $________ per share,  representing  the Fair Market
                  Value on the date of grant.

                  (e) No Right to Continued Employment. The grant of an Award to
         any  Participant  shall not be deemed for any purpose to  constitute  a
         right to continued  employment.  Unless otherwise set forth in writing,
         all Participants  shall remain "at will"  employees.  As a condition to
         accepting  any  Award,  each  Participant  relinquishes  any  claim  to
         continued  employment  and  covenants  not to sue  the  Company  or any
         affiliate for any action alleging a right to continued employment.

                  (f)      Adoption  Date.  This  Plan  was adopted  pursuant to
         action of the Board of  Directors on December 18, 1998.
