<PAGE>

                1.    The right of first refusal and option to purchase  granted
         to Lessee  herein shall be in effect only until the  expiration  of the
         term of the Lease  Agreement.  The right of first refusal and option to
         purchase set forth herein may not be exercised by Lessee if:

                      (a)   Lessee or a sublessee of Lessee authorized by Lessor
                is not in  possession  of the  Leased  Premises  under the Lease
                Agreement.

                      (b)   Lessee  is in  default  of any of the  terms  of the
                Lease Agreement.

                2.    Except as  otherwise  provided  for  herein,  in the event
         Lessor  desires to sell,  transfer or convey  Lessor's  interest in the
         Leased Premises, or any portion thereof, Lessor shall have the right to
         sell,  transfer or convey Lessor's interest in the Leased Premises,  or
         any  portion   thereof,   only  after   complying  with  the  following
         requirements:

                      (a)   Lessor shall  forward to Lessee by  certified  mail,
                return receipt requested,  at 4137 Commerce Circle, Idaho Falls,
                Idaho  83401,  or to such  other  address  as Lessee  shall have
                provided to Lessor in writing,  written notice containing all of
                the terms and conditions on which Lessor desires to give,  sell,
                transfer or convey the Leased  Premises,  or any portion thereof
                (the "Lessor's Notice of Transfer"). Said notice shall be deemed
                effective upon the date of its mailing.

                      (b)   Upon mailing of Lessor's  Notice of Transfer, Lessee
                shall then have the option to purchase the interest of Lessor in
                the Leased Premises, or such portion  thereof, as is referred to
                in Lessor's  Notice of Transfer upon the same terms as set forth
                in such notice.

                      (c)   Lessee  may  exercise  its  option  to  purchase  by
                mailing  its  written  notice  of  exercise  of option to Lessor
                within  fifteen (15) days from the date of mailing of the notice
                to Lessee.  Such notice of exercise of option shall be forwarded
                to Lessor by certified mail, return receipt  requested,  at Post
                Office Box 95, Rexburg, Idaho 83440, or to such other address as
                may be designated  in writing to Lessee by Lessor.  In the event
                Lessee  exercises  such  option,  then  Lessee and Lessor  must,
                within  fifteen  (15) days after the  exercise  of such  option,
                enter into a binding  written  agreement for the transfer and/or
                the  purchase of the  Leased  Premises  upon the same  terms and
                conditions  set  forth  in  Lessor's  Notice  of  Transfer.  Not
                withstanding  anything  contained in the Lease  Agreement to the
                contrary, if Lessee exercises such option to purchase,  then the
                term of the Lease  Agreement  shall expire on the day of closing
                of the sales transaction.

                      (d)   In the event that Lessee does not desire to exercise
                Lessee's option to purchase,  Lessee shall,  within fifteen (15)
                days of the  mailing of  Lessor's  Notice of  Transfer,  mail by
                certified mail, return receipt requested, to Post Office Box 95,
                Rexburg, Idaho 83440, or such other address as Lessor shall have
                provided  to Lessee in writing,  Lessee's  notice to Lessor that
                Lessee will not exercise said option. If Lessee fails to provide
                such  notice  that Lessee will not  exercise  such  option,  and
                Lessee does not  exercise  the option as  provided in  paragraph
                2(c),  then  Lessor  is  hereby  empowered  to  record  Lessor's
                affidavit to the effect that Lessee did not timely exercise said
                option, which affidavit shall be conclusive as against Lessee of
                Lessee's  failure to exercise  such  option.  If Lessee fails to
                exercise  such option in the manner  provided in paragraph  2(c)
                above, then Lessor shall have the right to forthwith transfer or
                convey the Leased Premises or any portion thereof free and clear
                of this right of first  refusal to  whomsoever  Lessor  desires,
                provided  that:  (i)  such  sale,   transfer  or  conveyance  is
                consummated  within  one  hundred  eighty  (180)  days after the
                expiration of the time for Lessee to accept the offer, (ii) such
                sale,  transfer or  conveyance  is made in  accordance  with the
                terms and conditions set out in Lessor's Notice of Transfer, and
                (iii) the purchaser shall receive the Leased Premises subject to
                any remaining rights and obligations  Lessor and Lessee may have
                under the Lease  Agreement.  If Lessee  fails to  exercise  such
                option in the manner  provided in paragraph 2(c) above,  then in
                such event Lessor shall have the right to forthwith  transfer or
                convey the Leased Premises or any portion thereof free and clear
                of the option to purchase hereinafter set forth.

                      (e)   Notwithstanding  anything to the contrary herein, it
                is  specifically  understood and agreed that this right of first
                refusal shall not apply to any transfer,  either with or without
                consideration,  or whether by will, agreement,  operation of law
                or otherwise, by Lessor to Immediate Family.  "Immediate Family"
                means for  purposes of this  paragraph,  Adrian Rand Robison and
                Dorothy  Robison,  husband and wife,  the lineal  descendants of
                Adrian Rand Robison and Dorothy Robison, the spouses of any such
                lineal  descendants  and the trustees of any trusts in which the
                beneficiaries of such trusts are any of the foregoing  mentioned
                parties. Any such transfer to Immediate Family shall be subject,
                however,   to  the  right  of  first  refusal  granted  by  this
                Agreement,  and the  Immediate  Family  shall be bound to comply
                with this right of first refusal and any subsequent  transfer of
                the Leased Premises or any portion thereof.

                4.    Subject to the  termination  of the option  granted herein
         under the conditions  set forth in paragraph 2(d) above,  Lessor grants
         unto Lessee the exclusive  right and option,  if Lessee shall not be in
         default of any of the terms of the Lease  Agreement,  to  purchase  the
         Leased Premises and any additions and  improvements  thereon,  together
         with any  improvements  that may have been made during the term of  the
         Lease   Agreement,   upon  and  subject  to  the  following  terms  and
         conditions:

                      (a)   Said option shall be  exercisable  only prior to the
                expiration of the term of the Lease Agreement.

<PAGE>

                      (b)   To exercise  this option,  Lessee  shall  deliver to
                Lessor  written  notification  of the date upon which  Lessor is
                prepared to purchase and close the  transaction  upon  the terms
                provided herein;  provided,  however, that Lessor shall be given
                at least thirty (30) days notice of the date of such closing.

                      (c)   Within sixty (60) days after giving  written  notice
                of Lessee's  intent to exercise the option to  purchase,  Lessee
                shall  purchase the Leased  Premises and the closing to complete
                such  purchase  shall be  completed  within  said sixty (60) day
                period.

                      (d)   If Lessee properly  exercises the option to purchase
                set forth herein, the Leased Premises shall be sold to Lessee by
                Lessor and Lessee shall purchase the Leased Premises pursuant to
                the following terms and provisions:

                            (i)   For  purposes of this  subparagraph  the  term
                      "CPI"  shall refer to the CPI  published  by the Bureau of
                      Labor Statistics of the United States  Department of Labor
                      for All Urban  Consumers,  U.S.  City Average (All Cities)
                      for all  items  with the  index  base  being  the  current
                      official  base  of  1982-1984 = 100.  If  Lessee  properly
                      exercises the option to purchase  prior to the  expiration
                      of the initial five (5) year term of the Lease  Agreement,
                      the  purchase  price  shall  be  computed  as  follows:  a
                      fraction shall be created, the denominator of which is the
                      CPI for December,  2003,  and the numerator of which shall
                      be the CPI on the last day of the month  prior to the date
                      of closing.  This  fraction  then shall be  multiplied  by
                      $480,000.00.  The  purchase  price shall be the higher of:
                      (i)  $480,000.00 or (ii) the amount which is arrived at my
                      multiplying $480,000.00 by the above referred to fraction.

                            (ii)  If Lessee exercises the option to purchase set
                      forth herein after the  expiration of the initial five (5)
                      year term of the Lease  Agreement,  the purchase  price of
                      the Leased  Premises shall be the fair market value of the
                      Leased  Premises at the time Lessee  exercises the  option
                      to  purchase.  If Lessee and Lessor  cannot agree upon the
                      fair  market  value  of the Leased  Premises,  the  Leased
                      Premises  shall be appraised.  If Lessee and Lessor cannot
                      agree  on  an  appraiser,   they  shall  each  appoint  an
                      appraiser. If the two (2) appraisers cannot agree upon the
                      fair  market  value of the  Leased  Premises,  they  shall
                      appoint a third appraiser,  and the decision of a majority
                      of the  three  (3)  appraisers  shall  be  binding  on all
                      parties. The cost of the appraisal shall be shared equally
                      by the Lessor and the Lessee.

                            (iii) At closing,  Lessor shall execute a Grant Deed
                      and deliver such Grant Deed to Lessee for recording  which
                      such  Grant  Deed  shall  transfer  title  to  the  Leased
                      Premises  to  Lessee.   The  Leased   Premises  shall   be
                      transferred appeal,  which the offended party may incur in
                      enforcing this Agreement or in pursuing any remedy allowed
                      by law for breach hereof,  whether such is incurred by the
                      filing of suit or otherwise.
