any other  cause,  similar  or  dissimilar,  beyond  the  reasonable  control of
Landlord. Landlord shall be liable in case of negligence under any circumstances

               without  limiting  Landlord  in the  exercise  of any other legal

               has failed to observe, or (b) surrender the Premises to Landlord.
               all in accordance  with Title 78, Chapter 36 of the Utah Code. In
               the event Landlord may recover from Tenant:

                    (i)  The worth at the time of award of any unpaid rent which
                         had been earned at the time of such termination; plus

                    (ii) The  worth at the time of award of the  amount by which
                         the unpaid  rent which  would  have been  earned  after
                         termination  until the time of award exceeds the amount
                         of rental loss that could have been reasonably avoided;
                         plus

                                       15



                    (iii)The  worth at the time of award of the  amount by which
                         the unpaid  rent for the  balance of the term after the
                         time of award  exceeds  the amount of such  rental loss
                         that could be reasonably avoided; plus

                    (iv) At Landlord's election.  such other amounts in addition
                         to or in lieu of the foregoing as may be permitted from
                         time to time by applicable law including treble damages
                         as permitted by Title 78, Chapter 36; less

                    (v)  Any amounts by which Landlord is benefited by reason of
                         not having to incur Operating Expenses  associated with
                         Tenant's  occupancy.  The term  "rent"  as used  herein
                         shall be deemed to be and to mean the Base Rent and all
                         other sums.  including  but not  limited to  Additional

                         above terms of this Lease.  As used in  paragraphs  (1)
                         and (ii) above,  the worth at time of award is computed
                         by allowing interest at the rate of the Federal Reserve
                         Bank of San  Francisco  at the time of  award  plus one
                         percent (1%).

          b)   Except as may be  required  otherwise  under state  statutory  or
               common law,  Landlord can  continue  this Lease in full force and
               effect.  regardless of whether or not Tenant is in default or has
               abandoned the Premises, and this Lease will continue in effect as
               long as Landlord does not terminate  Tenant's right to possession
               and  Landlord  shall have the right to collect rent when due with
               allowance for reduced Operating Expenses. In addition:

                    (i)  During the period  Tenant is in default  and shall have
                         vacated the Premises,  Landlord.  at its election,  may
                         enter the  Premises  and re!et them or any part of them
                         upon  such  terms as  Landlord  in its sole  discretion
                         shall  deem   appropriate.   Any  rentals  received  by
                         Landlord from such reletting  shall be applied:  first,
                         to the payment of any indebtedness  other than rent due
                         hereunder  from  Tenant  to  Landlord;  second,  to the
                         payment of any cost of such reletting,  including,  but
                         not  limited  to  leasing  commissions  and  reasonable
                         attorney's fees incident to such default,  re-entry and
                         reletting;  third,  to the  payment  of the cost of any
                         alterations  and  repairs  to the  Premises  caused  by
                         Tenant's  damage  to  the  Premises,  normal  wear  and
                         excepted;  and  fourth,  to the payment of rent due and
                         unpaid  hereunder.  Tenant shall pay any  deficiency in
                         such amounts,  as  determined by Landlord,  to Landlord
                         within ten (10) calendar days of receipt of a statement
                         setting forth the amount of such deficiency.

                    (ii) Neither  Landlord's acts of maintenance or preservation
                         or efforts to relet the Premises,  nor the  appointment
                         of a receiver  upon the  initiative  of the Landlord to
                         protect  Landlord's  interest  under  this  Lease,  nor
                         re-entry  or  taking  possession  of  the  Premises  by
                         Landlord  pursuant  to this  ARTICLE  26.00,  shall  be
                         construed  as an  election to  terminate  this Lease or
                         constitute  a   termination   of  Tenant's   rights  to
                         possession,  nor shall it cause a  forfeiture  of rents
                         and  other  amounts  remaining  to be paid  during  the
                         balance  of the  term of  this  Lease  unless  Landlord
                         notifies  Tenant in  writing  that  Landlord  elects to
                         terminate this Lease, or unless  termination is decreed
                         by a court of competent jurisdiction.

                    (iii)Notwithstanding  any reletting  without  termination by
                         Landlord because of any default by Tenant, Landlord may
                         at any time after  reletting  elect to  terminate  this
                         Lease for any such default.

                                       16


          c)   In the  event of any such  default  and  abandonment  by  Tenant,
               Landlord  shall also have the fight to reenter the  Premises  and
               remove all persons and property from said Premises; such property
               may be removed  and stored in a ware  house or  elsewhere  at the
               cost of and for the account of Tenant.

27.00 DESTRUCTION BY FIRE OR CASUALTY

     Subject to provision for termination immediately below, if the Premises are
destroyed or partially destroyed by fire, or other perils covered or not covered
by extended coverage insurance, then, on the day after damage occurs, rent shall
abate and the lease term shall be extended  until such time as the  Premises are
rendered  reasonably  habitable  for normal  business use. The opinion of an MAI
appraiser mutually  acceptable to both parties shall be binding upon the parties
in effecting the  determination as to whether the Premises can be used by Tenant
to conduct  business at the same scale as before the damage  occurred,  the term
shall abate. If the whole of the Premises or any major portion thereof, as would
affect  the  Tenant's  occupation  and use of the  Premises,  shall be  rendered
untenantable for any other reason other than the fault of the Tenant, this Lease
shall  terminate  at the  election of the  Landlord  or the Tenant upon  written
notice to Landlord  given  within  sixty (60)  calendar  days of the  occurrence
advising of the termination and the grounds  therefore.  If Landlord repairs the
Premises to a habitable condition,  then rental and term shall recommence on the
first day of the calendar month  following the date the Premises are placed in a
habitable condition.  Landlord shall have the option not to terminate this Lease
in the event such destruction resulted from the negligent or intentional acts or
omissions of Tenant or any of Tenant's  agents,  employees  or invitees,  and in
such  event,  Tenant  shall  continue to be  responsible  for all rent and other
obligations under this Lease.

     27.01  ABATEMENT  OF RENTS;  TENANTS  LIABILITIES:  If the  Premises or the
Office  Building is damaged,  but the  Premises  and Office  Building  are still
habitable for normal  business  use, and Landlord or Tenant  repairs or restores
them pursuant to the provisions of this ARTICLE 27.00 the rent payable hereunder
for the period  during such damage,  repair or  restoration  continues  shall be
abated in proportion to the reduced  amount of usable square footage of Tenant's
Premises. Notwithstanding anything to the contrary contained herein Tenant shall
not be entitled to an abatement  of rent if the Premises or the Office  Building
was damaged due to the negligent or intentional act or omission of Tenant or any
of Tenant's agents or employees or invitees,

     27.02  REPAIR OF TENANT'S  PROPERTY:  Except as provided in ARTICLE  27.00,
Landlord shall not be required to make any repairs or  replacements of any other
kind, or to make any repairs or replacements of any panels,  decoration,  office
fixtures, railings, floor coverings, partitions, or any other property installed
in the  Premises  by  Tenant.  Tenant  shall  obtain  its own fire and  casualty
insurance  to protect  against  loss in the event of damage to such  elements by



                                       17




fire or other perils  covered by extended  coverage  insurance.  Tenant shall be
obligated to obtain a waiver of subrogation in such policies and hereby releases
and indemnifies Landlord from any claims as a result of such casualty.

     27.03  EXCLUSIVE   REMEDY:   The  Tenant  shall  not  be  entitled  to  any
compensation  or damages  from  Landlord for loss of the use of the whole or any
part of the Premises or of Tenant's personal property,  or for any inconvenience
or annoyance occasioned by such damage, repair, reconstruction,  or restoration,
except the  abatement of rent  specified in this ARTICLE  27.00 unless caused by
Landlord's negligence or misconduct.

28.00 EMINENT DOMAIN

     In the event the entire  Premises shall be  appropriated or taken under the
power of eminent  domain by any  public or  quasi-public  authority,  this Lease
shall terminate and expire as of the date of such taking,  and both Landlord and
Tenant shall  thereupon be released from any  liability to the other  thereafter
accruing  hereunder.  In the event more than  twenty-five  percent  (25%) of the
square footage of floor area  (including  mezzanine,  if any) of the Premises is
taken under the power of eminent domain by any public or quasi-public authority,
or if by reason of any  appropriation  or  taking,  regardless  of the amount so
taken,  the  remainder  of the Premises is not usable for the purposes for which
the Premises were leased, then either Landlord or Tenant shall have the right to
terminate  this Lease as of the date  Tenant is  required to vacate a portion of
the  Premises  so taken  upon  giving  notice  to the other in  writing  of such
election  within sixty (60) calendar days after the date of such taking.  In the
event of such termination,  both Landlord and Tenant shall thereupon be released
from any liability to the other thereafter accruing hereunder.

     28.01 COMPENSATION: Whether or not this Lease is terminated, Landlord shall
be entitled to the entire award or compensation in such proceedings, but nothing
herein shall be deemed to affect  Tenant's  right to bring a separate  action to
recover  damages  for  the  loss of its  leasehold  improvements,  fixtures  and
personal  property.  If this Lease is terminated as  hereinabove  provided,  and

provisions  of this Lease all items of rent,  additional  rent and other charges

Landlord's  cost and expense,  to, as soon as reasonably  possible,  restore the
remaining  potion  of the  Premises  to a  complete  unit  of like  quality  and
character as existed prior to such  appropriation or taking;  and thereafter the

29.00 SUBORDINATION AND ATTORNMENT

     This Lease is subject and  subordinate  to all mortgages and deeds of trust
which now affect the Office  Building or any part of the Office  Building and to
all renewals, modifications, consolidation, replacements and extensions thereof.
This Lease may, at the option of Landlord, be subordinate to mortgages, deeds of
trust or other lien which may hereafter  affect the Office  Building or any part
thereof and Tenant will  execute  and deliver  upon the demand of Landlord  from
time to time any and all instruments desired by Landlord,  subordinating, in the
manner requested by Landlord,  this Lease to such lease, mortgage, deed or trust
or lien,  provided  such  mortgage,  deed or trust or lien  provides that in the
event of the termination of foreclosure of such mortgage, deed of trust or lien,
any  successor  to any  interest  of Landlord  in the Office  Building  will not
disturb Tenant's  possession of the Premises if Tenant attorns to such successor
as Landlord and  otherwise  performs its  obligations  under this Lease.  Tenant
agrees  that Tenant  shall  attorn to any  purchaser  upon  foreclosure  or sale
pursuant to any lien.  In the event of  foreclosure  of such  mortgage,  deed of
trust or other lien,  any  successor  to any  interest of Landlord in the Office
Building shall have no liability to repay to Tenant any security deposit paid to
any  prior  Landlord.  Landlord  may from  time to time  grant or  declare  such
restrictions or covenants as may be reasonably required by Landlord or adopt and
record  such  parcel  maps,  subdivision  maps or  condominium  plans  as may be
reasonably  required  by  Landlord  relating to all or any portion of the Office
Building and the provisions of all such documents  shall be senior to this Lease
and Tenant shall sign any of such  documents  upon request of Landlord  provided
such  documents  do not  reasonably  interfere  with the use of the  Premises by
Tenant as permitted by this Lease.

30.00 ASSIGNMENT, SUBLETTING AND OWNERSHIP

     Except as provided herein, Tenant shall not voluntarily, or by operation of
law, transfer, assign, sublet, or otherwise transfer or encumber all or any part
of Lessee's interest in this Lease or in the Premises.  Any attempt at transfer,
assignment or  subletting,  without the  Landlord's  written  consent (when such
consent is required)  shall be void and confer no rights upon any third  person.
Notwithstanding the foregoing, Tenant may assign or sublet this Lease upon first
procuring  the  written  consent  of  Landlord,   which  consent  shall  not  be
unreasonably  withheld by Landlord.  (i) Said assignee shall assume in full, the
obligations  of Tenant under this Lease and (ii) Landlord shall be given written
notice of such assignment and assumption.  Any such assignment shall not, in any
way,  affect or limit the  liability  of Tenant  under the terms of this  Lease.
Without  limiting the  generality of the foregoing,  Landlord's  refusal to give
consent to an assignment or sublease shall not be deemed  unreasonably  withheld
if:

                    (i)  The  proposed  use of the  Premises  shall be different
                         from that  permitted  under ARTICLE 1.08 of this Lease;
                         or

                    (ii) The character,  reputation or financial  responsibility
                         of  the  proposed   assignee  or   sublessee   are  not
                         reasonably  satisfactory in Landlord's judgment; or, in
                         any event,  not at least  equal to those  possessed  by
                         Tenant (or represented to be possessed by Tenant) as of
                         the date of execution of this Lease; or


                                       19






                    (iii)The  proposed  assignee  fails to agree in  writing  to
                         assume and be bound by all of the obligations of Tenant
                         under this Lease.

     No consent to assignment given by Landlord  pursuant to the foregoing shall
be deemed to release Tenant from any liability under this Lease,  nor, after any
consent to assignment, shall Landlord's failure to give Tenant notice of default
under any of the terms or  conditions  of this  Lease  release  Tenant  from any
liability  hereunder.  Without limiting any of the Landlord's  rights hereunder,
Landlord shall have the fight,  in the event of an assignment of this Lease,  to
declare  this  Lease null and void and of no  further  force and effect  thereby
permitting  Landlord to negotiate with the  prospective  assignee for a lease on
terms and conditions acceptable to Landlord.

     Notwithstanding  anything  contained  herein to the  contrary,  Tenant may,
without  the  necessity  of the  consent  of  Landlord,  at any time  assign  or
otherwise transfer this Lease or sublease the Premises or any portion thereof to
(i) any  parent,  subsidiary  or  affiliate  corporation  or  entity,  (ii)  any
corporation  resulting from the  consolidation  or merger of Tenant into or with
any other entity, or (iii) any person,  firm, entity or corporation  acquiring a
majority  of  Tenant's   issued  and   outstanding   capital  stock  or  all  or
substantially all of Tenant's assets;  provided no such assignment,  sublease or
transfer shall release Tenant from any of Tenant's obligations under this Lease.
As used herein, the expression "affiliate  corporation or entity" means a person
or business entity, corporate or otherwise, that directly or indirectly, through
one or more  intermediaries,  controls or is  controlled  by or is under  common
control with Tenant.  The word  "control"  means the right and power,  direct or
indirect,  to direct or cause the direction of the  management and policies of a
person or business entity, corporation or otherwise.

     30.01 ATTORNEY'S FEES:  Tenant agrees to reimburse  Landlord for Landlord's
attorney's fees in an amount not less than $500.00  incurred in conjunction with
the processing and  documentation  of any such requested  transfer,  assignment,
subletting.  change of  ownership  or  hypothecation  of this Lease or  Tenant's
interest in and to the Premises for which  Landlord's  consent is required.  The
consent by Landlord to any transfer, assignment. subletting, change of ownership
or hypothecation shall not constitute a waiver of the necessity for such consent
to  any  subsequent  attempted  transfer,  assignment,  subletting,  license  or
concession agreement, change of ownership or hypothecation.

     30.02  LANDLORD'S  CONSENT:  Each such  transfer,  assignment,  subletting,
license  or  concession  agreement  and  hypothecation  to which  there has been
consent shall be by instrument in writing, in form satisfactory to Landlord, and
shall  be   executed  by  the   translator,   assignor,   sublessor,   licenser,
concessionaire,   hypothecator   or  mortgagor  and  the  transferee   assignee,
sublessee, licensee, concessionaire, or mortgagee shall agree in writing for the
benefit of the  Landlord  to assume to be bound by,  and to  perform  the terms,
covenants and conditions  done, kept and performed by Tenant.  One executed copy
of such written  instrument  shall be  delivered  to Landlord.  Failure to first
obtain in writing  Landlord's  consent with the provisions of this ARTICLE shall
operate  to  prevent  any  such  transfer,  assignment,   subletting,   license,
concession agreement or hypothecation from becoming effective.

                                       20






     30.03 INVOLUNTARY ASSIGNMENT:  No interest of Tenant in this Lease shall be
assignable  by operation of law,  legal  process,  receivership,  bankruptcy  or
otherwise  ("involuntary  assignment").  An involuntary assignment shall include
but not be limited to the following:

                    (i)  If Tenant is or becomes  bankrupt or  insolvent,  makes
                         and  assignment  for  the  benefit  of  creditors,   or
                         institutes a  proceeding  under the  Bankruptcy  Act in
                         which  Tenant  is the  bankrupt;  or,  if  Tenant  is a
                         partnership  or  consists  of more  than one  person or
                         entity,  if any  partner  of the  partnership  or other
                         person or entity is or becomes  bankrupt or  insolvent,
                         or makes an  assignment  for the benefit of  creditors;
                         and/or

                    (ii) If a writ of attachment or execution is levied  against
                         Tenant's interest in on this Lease; or

                    (iii)If, in any  proceeding  or action to which  Tenant is a
                         party,  a receiver is appointed  with  authority to the
                         possession of the Premises.

     Any  involuntary  assignment  shall  constitute  a default by  Tenant,  and
Landlord  shall have the right to elect to terminate  this Lease,  in which case
this Lease shall not be treated as an asset of Tenant.  If a writ of  attachment
or execution is levied against Tenant's  interest in on this Lease or a receiver
is appointed for Tenant's business,  Tenant shall have thirty (30) calendar days
in which to cause the attachment or execution or receiver to be removed.  If any

sixty (60) calendar days in which to have the involuntary proceedings dismissed.

install or operate  any  phonograph,  radio  receiver,  musical  instrument,  or
television or other similar device in any part of the Common areas.  Tenant will
