instrumentality  having  jurisdiction  of  the  Property,   including,   without
limitation,  all applicable federal, state and local laws, rules, ordinances and
regulations  relating to the use, storage,  transportation,  and disposal of any
Hazardous  Materials on, in or under the Project,  and all  applicable  federal,
state and local laws, rules,  ordinances and regulations relating to wetlands or
endangered  species  protection and the effect of the development,  construction
and use of the Project on any wetlands or  endangered  species.  Borrower has no
knowledge  of  any  actions  or   proceedings   pending   before  any  court  or
administrative agency with respect to the validity of such laws, regulations and
ordinances or with respect to any certificates issued thereunder.

         3.6 Financial  Statements and Other Information.  Borrower has provided
Lender with copies of its audited financial  statements (the "Audited  Financial
Statements")   for  the  fiscal  year  ended  December  31,  1999.  The  audited
consolidated  financial  statements of Borrower  included in the Form 10-K filed
with the Securities and Exchange  Commission on March 30, 2000 (the "Form 10-K")
fairly present,  in conformity  with generally  accepted  accounting  principles
("GAAP") applied on a consistent basis, the consolidated  financial  position of
Borrower as at the dates thereof and the consolidated  results of its operations
and cash flows for the  periods  then  ended.  No  material  adverse  change has
occurred in the financial condition of Borrower reflected in the Form 10-K since
the dates thereof and no additional  borrowings  in excess of  $600,000.00  have
been  made by  Borrower  since  the  dates  thereof,  other  than the  borrowing
contemplated hereby. All other documents and information  delivered to Lender by
Borrower are accurate in all respects to Borrower's best knowledge.

         3.7 Hazardous Materials and Wetlands. No Hazardous Materials other than
as set forth in the  Environmental  Report are now located on the Property,  and
neither Borrower nor any other person has ever caused or permitted any Hazardous
Materials  to be  placed,  held,  located  or  disposed  of on,  under or at the
Property,  or any part thereof, in each case, except in full compliance with all
applicable   Environmental  Laws.  To  the  best  of  Borrower's  knowledge,  no
investigation,  administrative order, consent order and agreement, litigation or
settlement  with  respect  to  Hazardous  Materials  is  proposed,   threatened,
anticipated or in existence with respect the Property.  The  representations and
warranties  contained in this Section 3.7 shall survive the  reconveyance of the

                                       8


Trust Deed.  There are no wetlands on the  Property,  as wetlands are  regulated
pursuant to Section 404 of the Federal Water Pollution  Control Act (Clean Water
Act),  and the  regulations  promulgated  under  the  statute  or its  successor
statute.

         3.8 Title to  Property.  To the best of  Borrower's  actual  knowledge,
Ground  Lessor has good and  marketable  title to the  Property,  subject to the
terms and conditions of the Ground Lease.  Borrower has a leasehold  interest in
the Property under the Ground Lease, subject only to the Permitted Encumbrances.
The Property,  and any and all improvements  thereon,  are free and clear of all
liens and encumbrances, excepting the Permitted Encumbrances.

         3.9 Commission.  No brokerage or other fee,  commission or compensation
is to be paid by Lender,  and Borrower hereby indemnifies Lender against any and
all claims for  brokerage  fees or  commissions  which may be  asserted  against
Lender,  and hereby agrees to pay all expenses  incurred by Lender in connection
with the  defense  of any  action or  proceeding  brought  to  collect  any such
brokerage fees or commissions,  including but not limited to costs and attorneys
fees.

         3.10 Americans with  Disabilities Act. The Project is accessible to and
usable by persons with disabilities  pursuant to the accessibility  requirements
of  the  Americans  With  Disabilities  Act  (the  "Act"),  and  all  applicable
regulations  promulgated by the U.S.  Architectural and Transportation  Barriers
Compliance Board, by the U.S. Department of Justice, and by all other applicable
agencies. The Project will comply with all accessibility requirements of the Act
and   regulations,   together  with  the  requirements  of  the  Americans  With
Disabilities Act Accessibility Guidelines for Buildings and Facilities.

                                    ARTICLE 4

Project from the Title Company on a current ALTA  extended  form coverage  basis
which is acceptable  to Lender (the "Title  Commitment").  The Title  Commitment
shall have  attached  copies of all  instruments  which appear as  exceptions to
title in the  Title  Commitment.  The  Title  Commitment  shall  also  include a
judgment search respecting  Borrower and any other party that holds title to all
or any portion of the Project.

         4.3 Opinion of Counsel.  If required by Lender,  Borrower has delivered

Lender have been fully executed and the original executed documents delivered to
Lender.

         4.7 Recording and Filing of Loan  Documents.  All of the Loan Documents
which require  filing or recording have been properly filed and recorded so that
all of the liens and security interests granted to Lender in connection with the
Loan will be properly  created and perfected and be first  priority liens on the

         4.8 First Lien on Collateral.  The Trust Deed and other applicable Loan
Documents  shall  constitute and create a valid first lien upon the  Collateral,
free of any prior mechanic's liens or materialmen's liens or special assessments
for work completed or under  construction on or before the Closing Date, subject
only to the Permitted Encumbrances.

         4.9  Ground   Lease.   Borrower  has  provided   Lender  with  evidence
satisfactory  to Lender  that the  Ground  Lease is in full force and effect and
that no default has occurred  under the Ground Lease and no events have occurred

default under any of the Leases.

                                    ARTICLE 5

                              COVENANTS OF BORROWER

         Borrower agrees and covenants with Lender as follows:

         5.1 Assignment.  Borrower shall not,  without the prior written consent
of Lender,  mortgage,  assign, convey, transfer, sell or otherwise dispose of or
encumber the  Project,  Borrower's  interest in the Project,  or any part of the
Project, or the income to be derived from the Project.

                                       10


         5.2 Right of Inspection.  Lender or Lender's  agents shall at all times
during the term of the Loan and at  Borrower's  expense  have the right of entry
upon and have free  access to the  Project  and have the  right to  inspect  all
books, contracts and records of Borrower relating thereto.

         5.3  Insurance.  Borrower  shall provide and  maintain,  or cause to be
provided and maintained,  at all times,  the insurance  policies  required to be
provided  and  maintained  pursuant  to the  Ground  Lease,  and  the  following
insurance policies:

                  5.3.1 Liability Insurance. Bodily injury and general liability
insurance  with a single  limit  per  accident  or  occurrence  of not less than
$1,000,000.00 acceptable to Lender insuring against any and all liability of the
insured  with respect to the Project or arising out of the  maintenance,  use or
occupancy thereof.

                  5.3.2 Property Hazard Insurance.  Multi-peril  property damage
insurance,  including, without limitation, fixtures and personal property to the
extent they are maintained on the Property,  and providing,  as a minimum,  fire
and extended  coverage  (including all perils  normally  covered by the standard
"all risk"  endorsement,  if such is available) on a full replacement cost basis
in an  amount  not less than 100% of the  insurable  value of the  improvements,
exclusive of the Property,  foundations  and other items normally  excluded from
coverage (based upon current replacement cost), with a single limit per accident
or occurrence of not less than $1,000,000.00.

                  5.3.3 Worker's Compensation  Insurance.  Worker's compensation
insurance  against  liability from claims of worker's with respect to and during
the period of any work on or about the  Property.  Borrower  shall  require  the
Contractor and each of Borrower's subcontractors employed to perform work on the
Property to deliver a certificate of worker's  compensation  insurance  prior to
the commencement of any work on the Property.

                  5.3.4 Flood  Insurance.  Flood  insurance  covering either the
Principal  Amount or the maximum  amount of  insurance  available,  whichever is
more, or in lieu of such flood insurance, evidence, satisfactory to Lender, that
no part of the  Project  is, or will be,  within an area  designated  as a flood
hazard area by the Federal Insurance  Administration,  Department of Housing and
Urban Development.

                  5.3.5  Policies  and  Premiums.   All  policies  of  insurance
required pursuant to this Section 5.3 shall be in form and substance  acceptable
to Lender and issued by insurance  companies  acceptable to Lender. No insurance
company shall be acceptable to Lender unless it has a company rating of not less
than "A" and a  financial  rating of not less than Class VII in the most  recent
edition of "Best's  Insurance  Reports".  All  policies  of  insurance  required
pursuant  to the  provisions  of this  Section  5.3  shall  contain  a  standard
"mortgagee  protection  clause",  shall have  attached a "lender's  loss payable
endorsement",  and shall name Lender as an additional  insured or loss payee, as
appropriate. All such policies shall contain a provision that such policies will
not be cancelled or materially amended by reduction of coverage by more than ten
percent (10%) without at least thirty (30) days prior written notice to Lender.

                                       11


         If Lender consents to Borrower  providing any of the required insurance
through  blanket  policies  carried  by  Borrower  and  covering  more  than one
location, then Borrower shall cause the insurance company to deliver to Lender a
certificate  of  insurance  in the form ACORD 27 of such policy which sets forth
the  coverage,  the limits of  liability,  the name of the  carrier,  the policy
number,  expiration  date and a statement  that the  insurance  company will not
cancel or  materially  modify by  reduction of coverage by more than ten percent
(10%) the coverage  evidenced by the endorsement  without first affording Lender
at least thirty (30) days prior written  notice.  In the event Borrower fails to
provide,  maintain, keep in force or deliver to Lender the policies of insurance
required by this Section 5.3,  Lender may, but without any  obligation to do so,
procure such  insurance for such risks covering  Lender's  interest and Borrower
shall pay all premiums thereon promptly upon demand by Lender. If Borrower fails
to pay any premiums  after demand by Lender,  Lender,  at Lender's  option,  may
advance any sums necessary to maintain and to keep in force such insurance.  Any
sums so advanced,  together  with interest on such sums at the then current rate
under the Note, shall be secured by the Trust Deed.

         Borrower  shall deliver to Lender a copy of the original of each of the
policies of insurance that Borrower is required to obtain and maintain, or cause
to be provided and maintained, under this Agreement.

         5.4 Repair and  Restoration.  If the  Project  is  partially  or wholly
damaged or destroyed by fire or any other cause, and (a) all insurance  proceeds
received by Lender  together with any cash funds delivered by Borrower to Lender
are  sufficient to fully restore and repair the Project as determined by Lender,
in Lender's sole discretion, and (b) Borrower is not in default under any of the
Loan  Documents,  Lender shall  disburse  such  proceeds in the manner  provided
herein for the  disbursement of the proceeds of the Loan toward the cost of such
restoration and repair.  If Lender  determines that such proceeds  together with
any cash funds  provided  by  Borrower  are  insufficient  to fully  restore the
Project,  Lender will apply any sums received by Lender under this Section first
to the payment of all of Lender's costs and expenses  (including but not limited
to legal fees and costs) incurred in obtaining those sums, and then, in Lender's
sole  discretion  and without  regard to the  adequacy of its  security,  to the
payment  of the  Loan.  If the  amount  of such  proceeds  exceeds  the  cost of
restoration  of the  Project,  Lender  shall  apply the excess  proceeds  to the
payment of the Loan.  If the  proceeds  of  insurance  are used to  restore  the
Project  and if the total  estimated  cost to restore  the  Project  exceeds the
amount of the proceeds of insurance,  Borrower  shall deliver to Lender prior to
any  disbursement  of the  proceeds  of  insurance,  an  amount  equal  to  such
difference  in  cash or cash  equivalents  satisfactory  to  Lender.  After  all
obligations of Borrower  under the Loan  Documents have been paid in full,  then
all proceeds in excess of such obligations will be paid to Borrower.

         5.5 Taxes and  Impositions.  Borrower  shall promptly pay and discharge
all lawful federal and state taxes and  assessments  imposed upon the Project or
upon Borrower  before they become past due and delinquent in accordance with the
procedures and upon the terms set forth in the Trust Deed.

         5.6  Hazardous  Materials.  Borrower  shall  not  cause or  permit  any
Hazardous  Materials to be placed,  held, located or disposed of on, under or at
the Project or any part thereof which are in violation of any Environmental Laws
or  the  Ground  Lease.  Borrower  further  agrees  to  give  notice  to  Lender
immediately upon Borrower's  learning of the presence of any Hazardous Materials

                                       12


on the Property, to promptly comply with any governmental requirements requiring
the removal,  treatment or disposal of such Hazardous Materials,  and to defend,
indemnify and hold harmless Lender from any and all liabilities,  claims, losses
or costs (including, without limitation attorneys' fees) which may now or in the
future be paid,  incurred  or  suffered  by or  asserted  against  Lender by any
person,  entity or governmental agency with respect to the presence of Hazardous
Materials on the Property or discharge of Hazardous Materials from the Property.
Borrower's  covenants  in this  Section  shall  survive  payment of the Loan and
foreclosure or other transfer of the Property.

         At any time  Lender,  in good  faith,  has reason to believe  Hazardous
Materials  have been  placed,  held,  located or disposed of on, under or at the
Property or any part thereof,  other than as stated in the Environmental Report,
and upon written request by Lender and at Borrower's cost and expense,  Borrower
shall  provide  Lender  with  an  Environmental  Compliance  Audit  Certificate,
effective  as of a date no earlier than the date of the notice.  Borrower  shall
certify  to Lender in writing  within  thirty  (30) days of the notice  that the
Project is in full  compliance  with  Environmental  Laws. In the event Borrower
fails or refuses  promptly to provide  Lender with an  Environmental  Compliance
Audit  Certificate  when required,  Lender may, at Borrower's  risk and expense,
arrange to obtain such a certificate. In the event the Project is in a condition
such that an  Environmental  Compliance  Audit  Certificate  cannot  be  issued,
Borrower  agrees,  at its own cost and expense,  to take all action necessary to
bring the Project into compliance  with all  Environmental  Laws,  including all
remediation and clean-up,  so an Environmental  Compliance Audit Certificate can
be issued.  Lender and any  consultant  retained by or for the benefit of Lender
shall have the right, without further permission from or notice to Borrower,  to
enter upon the Project for the purpose of performing any  examination or testing
required in order to provide such a certificate,  and Borrower shall provide the
consultant with reasonable access to Borrower's  records for such purposes.  Any
costs incurred by Lender in obtaining  such a certificate  shall be added to the
Principal  Indebtedness and shall be immediately due and payable, and shall bear
interest at the default rate provided in the Note from the date  incurred  until
paid by Borrower.

         5.7 No Disposition or Merger Without Lender's  Consent.  Borrower shall
not enter into any  merger  with any third  party,  or  otherwise  dispose of an
aggregate of more than ten percent (10%) of the total value of Borrower's assets
as of the date of  disposition  other than in the ordinary  course of Borrower's
business.

         5.8 Leases. Borrower shall not enter into any lease or leases of all or
any portion of the Project without the prior written consent of Lender. Borrower
shall  maintain all such leases  approved by Lender,  which shall be included in
the  definition  of  "Leases"  under this  Agreement,  in full force and effect.
Borrower shall notify Lender of any breach of any of the terms and conditions of
any of the Leases within fifteen (15) days of such breach.  Borrower agrees that
the Leases shall not be materially amended or modified without the prior written
consent of Lender.

         5.9 Financial Statements.  Borrower covenants that it shall timely file
with the Securities and Exchange  Commission any and all reports  required to be
filed pursuant to the Securities and Exchange Act of 1934, as amended, including
any  applicable  extension  period.  As to all financial  statements and reports
which  Borrower has furnished or may in the future  furnish to Lender,  Borrower

                                       13


acknowledges  and  agrees  that it has a  fiduciary  duty to  ensure  that  such
statements and reports are accurate and complete.

         Until  requested  otherwise  by  Lender,  Borrower  shall  provide  the
following financial statements and reports to Lender:

                  5.9.1 Annual Reports. Furnish to Lender promptly following the
filing of such report with the Securities and Exchange  Commission (i) a copy of
Borrower's  Annual Report on Form 10-K for each fiscal year;  and (ii) copies of
any final management  letters or other final reports and schedules  submitted by
Borrower's  officers to  Borrower's  Board of  Directors,  which shall include a
consolidated  balance  sheet as of the end of such fiscal year,  a  consolidated
statement of income and a  consolidated  statement of cash flows of Borrower and
its subsidiaries  for such year,  setting forth in each case in comparative form
the figures from  Borrower's  previous  fiscal year,  all prepared in accordance
with  generally  accepted  accounting  principles  and  practices,  consistently
applied,  and audited by  nationally  recognized  independent  certified  public
accounts. If Borrower is no longer required to file Annual Reports on Form 10-K,
Borrower  shall,  within ninety (90) days  following the end of each  respective
fiscal year,  deliver to Lender a copy of such  balance  sheets,  statements  of
income and statements of cash flows.

                  5.9.2 Quarterly Reports.  Furnish to Lender promptly following
the filing of such report with the Securities and Exchange Commission, a copy of
each of  Borrower's  Quarterly  Reports  on Form  10-Q,  which  shall  include a
consolidated  balance sheet as of the end of the respective  fiscal  quarter,  a
consolidated  statement of income and  consolidated  statements of cash flows of
Borrower and its  subsidiaries  for the  respective  fiscal  quarter and for the
year-to-date,  setting forth in each case in  comparative  form the figures from
the  comparable  periods in Borrower's  immediately  preceding  fiscal year, all
prepared  in  accordance  with  generally  accepted  accounting  principals  and
practices (except as otherwise  permitted by Form 10-Q),  consistently  applied,
but all of which may be  unaudited.  If Borrower  is no longer  required to file
Quarterly  Reports on Form 10-Q,  Borrower  shall,  within  forty-five (45) days
following the end of each of the first three (3) fiscal  quarters of each fiscal
year, deliver to Lender a copy of such balance sheets,  statements of income and
statements of cash flows.

                  5.9.3 Monthly Reports.  Monthly financial statements,  limited
to an aging of payables and receivables,  prepared by Borrower for each calendar
month in a form  acceptable  to Lender,  shall be delivered to Lender within ten
(10) days of the end of each  month  during the term of the Loan.  The  complete
monthly financial statements shall be delivered to Lender within forty-five (45)
days of the end of each month  (excepting  sixty (60) days for December),  which
shall be prepared  consistently with accounting  standards acceptable to Lender,
and shall accurately  represent the actual financial condition of Borrower as of
the date thereof,  and  accurately  represent the results of operations  for the
period covered thereby.

                  5.9.4 Compliance Certificate. Concurrently with the submission
of the Form 10-Q, Borrower shall submit to Lender a compliance  certificate in a
form  acceptable to Lender  certifying  that Borrower is in compliance  with all
terms and conditions of this Agreement,  including compliance with the financial
covenants provided in this Section 5.9. The compliance certificate shall include
the data  and  calculations  supporting  all  financial  covenants,  whether  in
compliance  or  not,  and  shall  be  signed  by the  chief  executive  officer,
treasurer, or chief financial officer of Borrower.

                                       14


         If any  financial  reports  required to be provided by this Section 5.9
are not timely provided to Lender, then there shall be immediately due and owing
from  Borrower  to  Lender a late  fee of  $100.00  per day for each  delinquent
financial  report,  which  late fee shall be  payable  in cash.  Nothing in this
Section 5.9 shall be construed to alter,  impair or infringe upon Lender's right
to  declare an Event of Default as  provided  in this  Agreement  or to alter or
extend the time limits for cure of a non-monetary default as provided in Article
6 of this Agreement.

         5.10  Title  Policy.  Within  ten (10)  days  after the  Closing  Date,
Borrower  shall  deliver to Lender a policy of title  insurance  on the Property
which shall (a) be an ALTA extended coverage mortgagee's policy, (b) show Ground
Lessor as the sole owner of  marketable,  fee simple  title to the  Property and
Borrower as the sole ground lessee of the  Property,  (c) be in the total amount
of the  Principal  Amount,  and  (d) be  issued  by a  title  insurance  company
satisfactory to Lender through the Title Company (the "Title Policy"). The Title
Policy shall insure that the Trust Deed is a valid first  mortgage  lien against
the Property and that the Property is free and clear of all liens,  encumbrances
and other  exceptions  to title,  except the Permitted  Encumbrances.  The Title
Policy  shall  include  such  additional  terms and  special  endorsements  upon
issuance  as may be  required  by  Lender,  including,  but not  limited  to,  a
foundation  endorsement  (CLTA  102.5 or its  equivalent)  to the  Title  Policy
showing no encroachments.

         5.11     Required Notices.  Borrower shall give Lender prompt written
notice of the following:

                  5.11.1 Any asserted litigation of any kind which might subject
Borrower to any  liability  in an aggregate  amount in excess of  $1,000,000.00,
whether covered by insurance or not and any litigation involving the Property.

                  5.11.2 All  complaints  and charges  made by any  governmental
agency  affecting the Property or exercising  supervision or control of Borrower
or Borrower's business which may impair the security of Lender.

                  5.11.3 Any acceleration of any other indebtedness  incurred by
Borrower.

                  5.11.4 Any event or  conditions  which  constitute an Event of
Default  or, with the  passage of time or the giving of notice,  or both,  would
constitute an Event of Default.

                  5.11.5 Any material adverse change in the financial  condition
of Borrower.

         5.12 Change of Business. Borrower shall not materially modify or change
the nature or type of its business without the prior written consent of Lender.

         5.13  Dividends  and Loans.  Borrower  shall not (a) declare or pay any
dividends except as are mandatorily  required on Borrower's preferred stock, (b)
purchase, redeem, retire or otherwise acquire for value any of its capital stock
now or hereafter  outstanding in excess of $2,000,000.00  for any year, (c) make
any distribution of assets to its  stockholders,  investors,  or equity holders,
whether  in cash,  assets,  or in  obligations  of  Borrower,  (d)  allocate  or
otherwise set apart any sum for the payment of any dividend or distribution  on,
or for the  purchase,  redemption,  or  retirement  of any shares of its capital

                                       15


stock or equity interests in excess of  $2,000,000.00  for any year, or (e) make
any other  distribution  by  reduction of capital or otherwise in respect of any
shares of its capital stock or equity interests, in excess of $250,000.00. It is
expressly  agreed upon between  Borrower and Lender that this  covenant does not

         8.2      Arbitration Provisions.  This concerns the resolution of any
claim or controversy between or among the parties.  In this regard:

                  8.2.1 Any claim or  controversy  ("Dispute")  between or among
the parties, and their assigns,  including, but not limited to, Disputes arising
out of or relating to the Loan, the Collateral,  this  Agreement,  the Note, the
Loan  Documents,  this  Article 8  Arbitration  ("arbitration  clause"),  or any
related  agreements or  instruments  relating  hereto or delivered in connection
herewith  ("Related  Documents"),  and including,  but not limited to, a Dispute
based on or arising from an alleged  tort,  shall at the request of any party be
resolved by binding  arbitration in accordance  with the applicable  arbitration
rules  of  the  American  Arbitration  Association  ("the  Administrator").  The
provisions of this arbitration clause shall survive any termination,  amendment,
or expiration of this  Agreement or Related  Documents.  The  provisions of this
arbitration  clause shall supercede any prior  arbitration  agreement between or
among  the  parties.  If any  provision  of this  arbitration  clause  should be
determined to be unenforceable,  all other provisions of this arbitration clause
shall remain in full force and effect.

                  8.2.2 The arbitration  proceedings  shall be conducted in Salt
Lake  City,  Utah,  at a  place  to be  determined  by  the  Administrator.  The
Administrator  and the  arbitrator(s)  shall  have the  authority  to the extent
practicable  to take any  action to require  the  arbitration  proceeding  to be
completed and the  arbitrator(s)'  award issued within  one-hundred-fifty  (150)
days of the filing of the  Dispute  with the  Administrator.  The  arbitrator(s)
shall have the  authority to impose  sanctions on any party that fails to comply
with time periods imposed by the Administrator or the  arbitrator(s),  including
the sanction of summarily dismissing any Dispute or defense with prejudice.  The
arbitrator(s)  shall have the  authority  to resolve any Dispute  regarding  the
terms of this Agreement, this arbitration clause or Related Documents, including
any  claim or  controversy  regarding  the  arbitrability  of any  Dispute.  All
limitations periods applicable to any Dispute or defense,  whether by statute or
agreement,   shall  apply  to  any  arbitration  proceeding  hereunder  and  the
arbitrator(s)  shall have the authority to decide whether any Dispute or defense
is barred by a  limitations  period  and,  if so,  to  summarily  enter an award
dismissing  any Dispute or defense on that basis.  The  doctrines of  compulsory
counterclaim,   res  judicata,  and  collateral  estoppel  shall  apply  to  any
arbitration proceeding hereunder so that a party must state as a counterclaim in
the  arbitration  proceeding  any claim or  controversy  which arises out of the
transaction  or  occurrence  that is the  subject  matter  of the  Dispute.  The
arbitrator(s)  may in the  arbitrator(s)'  discretion  and at the request of any
party:  (1)  consolidate in a single  arbitration  proceeding any other claim or
controversy involving another party that is substantially related to the Dispute
where that other party is bound by an arbitration  clause with the Lender,  such
as borrowers, guarantors, sureties, and owners of collateral; (2) consolidate in
a  single  arbitration  proceeding  any  other  claim  or  controversy  that  is
substantially  similar to the Dispute;  and (3) administer multiple  arbitration
claims or  controversies  as class actions in accordance  with the provisions of
Rule 23 of the Federal Rules of Civil Procedure.

                                       20


                  8.2.3 The  arbitrator(s)  shall be selected in accordance with
the rules of the Administrator  from panels maintained by the  Administrator.  A
single  arbitrator  shall have  expertise in the subject  matter of the Dispute.
Where three arbitrators conduct an arbitration proceeding,  the Dispute shall be
decided by a majority vote of the three  arbitrators,  at least one of whom must
have  expertise  in the  subject  matter of the Dispute and at least one of whom
must be a practicing  attorney.  The arbitrator(s) shall award to the prevailing
party  recovery  of all costs and fees  (including  attorneys'  fees and  costs,
arbitration  administration  fees  and  costs,  and  arbitrator(s)'  fees).  The
arbitrator(s),  either during the pendency of the  arbitration  proceeding or as
part of the arbitration  award, also may grant provisional or ancillary remedies
including  but not  limited  to an  aware  of  injunctive  relief,  foreclosure,
sequestration,  attachment,  replevin,  garnishment,  or  the  appointment  of a
receiver.

                  8.2.4 Judgment upon an arbitration award may be entered in any
court having jurisdiction,  subject to the following limitation: the arbitration
award is  binding  upon the  parties  only if the amount  does not  exceed  Four
Million Dollars  ($4,000,000.00);  if the award exceeds that limit, either party
may  demand  the right to a court  trial.  Such a demand  must be filed with the
Administrator  within  thirty (30) days  following  the date of the  arbitration
award;  if such a demand is not made within that time period,  the amount of the
arbitration  award shall be binding.  The  computation of the total amount of an
arbitration  award shall include  amounts awarded for attorneys' fees and costs,
arbitration administration fees and costs, and arbitrator(s)' fees.

                  8.2.5  No  provision  of  this  arbitration  clause,  nor  the
exercise  of any rights  hereunder,  shall  limit the right of any party to: (1)
judicially or  non-judicially  foreclose  against any real or personal  property
collateral or other security; (2) exercise self-help remedies, including but not
limited to  repossession  and setoff  rights;  or (3) obtain from a court having
jurisdiction  thereover any provisional or ancillary  remedies including but not
limited to injunctive relief, foreclosure, sequestration,  attachment, replevin,
garnishment,  or the appointment of a receiver.  Such rights can be exercised at
any time,  before or during initiation of an arbitration  proceeding,  except to
the extent such action is contrary to the  arbitration  award.  The  exercise of
such rights shall not  constitute a waiver of the right to submit any Dispute to
arbitration, and any claim or controversy related to the exercise of such rights
shall be a Dispute  to be  resolved  under the  provisions  of this  arbitration
clause. Any party may initiate  arbitration with the Administrator,  however, if
any party initiates litigation and another party disputes any allegation in that
litigation,  the disputing  party-upon the request of the initiating  party-must
file a demand for arbitration with the Administrator and pay the Administrator's
filing fee.  The parties may serve by mail a notice of an initial  motion for an
order of arbitration.

                  8.2.6  Notwithstanding  the  applicability of any other law to
this Agreement,  the arbitration  clause,  or Related Documents between or among
the parties, the Federal Arbitration Act, 9 U.S.C. ss. 1 et seq., shall apply to
the construction and interpretation of this arbitration clause.

                                  MISCELLANEOUS

         9.1 Non-Waiver.  No advance of Loan proceeds under this Agreement shall
constitute a waiver of any of the  conditions to be performed by Borrower and in
the event Borrower is unable to satisfy any such conditions  Lender shall not be
precluded from declaring such failure to be an Event of Default.

         9.2 Derivative  Rights.  Any obligation of Lender to make disbursements
under this  Agreement  is  imposed  solely and  exclusively  for the  benefit of
Borrower  and  no  other  person,   firm  or   corporation   shall,   under  any
circumstances,  be deemed to be a beneficiary  of such  condition,  nor shall it
have any derivative claim or action against Lender.

         9.3 Survival. All representations, warranties and covenants by Borrower
shall survive the making of the disbursements  under the Loan and the provisions
of this  Agreement  shall be binding upon  Borrower,  Borrower's  successors and

         9.4 Conflict.  The Note, Trust Deed, and all other Loan Documents shall
be subject to all the terms, covenants,  conditions,  obligations,  stipulations

between the terms and conditions of this Agreement, the Note, Trust Deed, or any
other Loan Document, this Agreement shall prevail.

         9.5 Assignment.  Lender may assign the Loan  Documents,  in whole or in
part, to any other person,  firm or corporation  provided that all provisions of
this  Agreement  shall  continue  to apply in  conjunction  with the other  Loan
Documents. Borrower shall not assign this Agreement, or any interest of Borrower
in or to this Agreement, the Loan proceeds, or any of the Loan Documents without
the prior written consent of Lender. Any dissolution of Borrower or any transfer
of any  interest in the  Borrower  without the prior  written  consent of Lender
shall be assumed to be an assignment in violation of this Section.

         9.7 Indemnification. Borrower agrees to pay, protect, defend, indemnify
and hold harmless Lender for any and all claims and liabilities, and for damages
which may be awarded or  incurred  by Lender,  and for all  reasonable  attorney
fees, legal expenses,  and other  out-of-pocket  expenses  incurred in defending
such  claims,  arising  from  or  related  in any  manner  to  the  negotiation,
execution,  or performance by Lender of this Agreement,  the Loan Documents,  or
any of the agreements,  documents,  obligations, or transactions contemplated by
this Agreement,  including,  without  limitation,  any claims,  liabilities,  or
causes of actions  related to any Hazardous  Materials  located on, in, or under
the  Property,  but  excluding  any such claims  based upon breach or default by
Lender or gross negligence or willful misconduct of Lender. This indemnification
shall  survive the  payment of the Loan,  reconveyance  of the Trust  Deed,  and
termination of this Agreement.

         Lender  shall have the control of the defense of any such  claims,  but
agrees to act  reasonably  in the defense of any such  claims.  Lender is hereby
authorized to settle or otherwise  compromise  any such claims as Lender in good
faith determines shall be in its best interests.

         Any indemnification amount owing to Lender pursuant to this Section 9.7
shall  be  secured  by  the  Loan   Documents   and   Collateral   except  that,
notwithstanding  anything  to  the  contrary  in  this  Agreement  or  the  Loan
Documents,  any such indemnification amount owing to Lender shall not be secured
in any way by the  Property  on, in or under which any  Hazardous  Materials  is
located.

         9.8 Terms. Whenever used in this Agreement,  the singular shall include
the  plural,  the  plural  the  singular,  and the use of any  gender  shall  be
applicable to all genders.

         9.9 Joint and Several  Liability.  All  obligations  and liabilities of
Borrower  imposed in this Agreement,  or in any of the other Loan Documents upon
Borrower shall be joint and several.

                                       23


         9.10  Multiple  Borrowers.  If Borrower is  comprised  of more than one
person or entity,  the term Borrower shall refer to each such separate person or
entity,   and  the  obligations  of  Borrower  shall  apply   individually   and
collectively  to each such  person  and  entity,  unless  specifically  provided
otherwise in this Agreement.

         9.11  Disclosure of Financial and Other  Information.  Borrower  hereby
consents to Lender  disclosing  to any other lender who may  participate  in the
Loan,  any and all  information,  knowledge,  reports,  and records,  including,
without limitation,  financial statements,  relating in any manner whatsoever to
the  Loan  and  Borrower,   provided  that  any  other  such  lender  execute  a
confidentiality agreement in a form acceptable to Borrower and Lender.

         9.12  Invalidity.  The invalidity of any one or more or any part of the
conditions,   covenants,  articles,  sections,  phrases  or  sentences  of  this
Agreement shall not affect the remaining portions of this Agreement.

         9.13  Governing  Law. This  Agreement and all matters  relating to this
Agreement shall be governed by, construed and interpreted in accordance with the
laws of the State of Utah.

         9.14 No Partnership.  Nothing  contained in this Agreement or in any of
the other Loan  Documents  shall be  construed  as  creating a joint  venture or
partnership  between  Borrower and Lender.  There shall be no sharing of losses,
costs and expenses between  Borrower and Lender,  and Lender shall have no right
of control or  supervision  except as it may  exercise  its rights and  remedies
provided in the Loan Documents.

         9.15  Attorneys'  Fees.  Upon the  occurrence  of an Event of  Default,
Lender may employ an attorney or attorneys to protect Lender's rights under this
Agreement,  and Borrower shall pay Lender  reasonable  attorneys' fees and costs
actually incurred by Lender, whether or not action is actually commenced against
Borrower  by reason  of such  breach.  Borrower  shall  also pay to  Lender  any
reasonable  attorneys  fees and costs  incurred  by Lender  with  respect to any
insolvency or bankruptcy  proceeding or other action  involving  Borrower or any
guarantor as a debtor.  If Lender  exercises the power of sale  contained in the
Trust  Deed  or  initiates  foreclosure  proceedings,  Borrower  shall  pay  all
reasonable  costs  incurred and attorney fees and costs as provided in the Trust
Deed.

         9.16 Setoff.  In addition to any rights and remedies of Lender provided
by law, if any Event of Default  exists,  Lender is  authorized  at any time and
from time to time,  without  prior  notice to  Borrower,  any such notice  being
waived by Borrower to the fullest  extent  permitted by law, to setoff and apply
any and all deposits (general or special, time or demand,  provisional or final)
at any time held by  Lender to or for the  credit  or the  account  of  Borrower
against any and all  obligations  of Borrower  under the Loan or any of the Loan
Documents,  now or  hereafter  existing,  irrespective  of whether or not Lender
shall have made demand under the Loan, or otherwise,  or under any Loan Document
and although such amounts owed may be  contingent  or  unmatured.  Lender agrees
promptly  to notify  Borrower  after any such  setoff  and  application  made by
Lender; provided, however, that the failure to give such notice shall not affect
the  validity of such setoff and  application.  The rights of Lender  under this
Section 9.16 are in addition to the other rights and remedies  (including  other
rights of setoff) which Lender may have.

                                       24


         9.17 Waiver of Claims.  Borrower (i)  represents  that  Borrower has no
defenses to or setoffs against any  indebtedness or other  obligations  owing to
Lender or Lender's affiliates,  nor claims against Lender or Lender's affiliates
for any matter  whatsoever,  related or unrelated to any  indebtedness  or other
obligations owing to Lender or Lender's affiliates, and (ii) releases Lender and
Lender's  affiliates  from all claims,  causes of action,  and costs,  in law or
equity,  existing  as of the Closing  Date,  which  Borrower  has or may have by
reason of any matter of any conceivable kind or character whatsoever, related or
unrelated to any indebtedness or other  obligations  owing to Lender or Lender's
affiliates, including the subject matter of this Agreement. This provision shall
not apply to claims for performance of express contractual  obligations owing to
Borrower by Lender or Lender's affiliates.

         9.18 Severability of Invalid Provisions. With respect to this Agreement
and all  other  Loan  Documents,  any  provision  of  this  Agreement  which  is
prohibited or unenforceable in any jurisdiction  shall, as to such  jurisdiction
only, be ineffective only to the extent of such prohibition or  unenforceability
without  invalidating the remaining  provisions of this Agreement,  and any such
prohibition  or  unenforceability  in any  jurisdiction  shall not invalidate or
render unenforceable such provision in any other jurisdiction.

         9.19 Integrated Agreement and Subsequent Amendment. The Loan Documents,
and the other agreements,  documents, obligations, and transactions contemplated
by this Agreement  constitute the entire  agreement  between Lender and Borrower
with respect to the subject matter of these  agreements,  and may not be altered
or amended except by written  agreement signed by Lender and Borrower.  PURSUANT
TO UTAH CODE SECTION  25-5-4,  BORROWER IS NOTIFIED THAT THESE  AGREEMENTS ARE A
FINAL  EXPRESSION  OF THE  AGREEMENT  BETWEEN  LENDER  AND  BORROWER  AND  THESE
AGREEMENTS MAY NOT BE CONTRADICTED BY EVIDENCE OF ANY ALLEGED ORAL AGREEMENT.

         All   prior   and   contemporaneous   agreements,    arrangements   and
understandings between the parties to this Agreement as to the subject matter of
this Agreement,  are, except as otherwise  expressly provided in this Agreement,
rescinded.
