Obligations  (subject,  however,  to  the  effects  of  bankruptcy,  insolvency,
reorganization,  moratorium,  and  similar  laws  from  time to  time in  effect
relating  to the  rights  and  remedies  of  creditors  as  well  as to  general

         first priority security interest.

                           (2)      Debtor agrees not to change the  location of

If certificates of title or other documents  evidencing  ownership or possession
of the  Collateral  are issued or  outstanding,  upon the request of the Secured
Party,  Debtor  will cause the  interest of Secured  Party to be properly  noted
thereon and will, forthwith upon receipt,  deliver same to Secured Party. If any
Collateral  is at any time in the  possession  or control  of any  warehouseman,
bailee, agent or independent contractor,  upon the request of the Secured Party,
Debtor shall notify such person or entity of Secured Party's  security  interest

to Debtor's  instructions,  or, if an Event of Default has  occurred  hereunder,
shall have occurred and be continuing, subject to Secured Party's instructions.

                  (d)      Maintenance  of   Existence.   Debtor  will  maintain

of any person or entity  other than Secured  Party  except in Debtor's  ordinary

operating  condition,  repair  and  appearance  as it was on the  date  of  this
Agreement, ordinary wear and tear excepted.

                  (g)      Event of Loss with Respect to the Alabama Project and

Collateral.  Upon the occurrence of an event of loss with respect to the Alabama
Project or the  Collateral,  Debtor shall forthwith (and in any event within ten

Debtor's  Obligations  under the Promissory Note and the Transaction  Documents,
subject,  however,  to the Debtor's set off rights described in Section 2 hereof
and  in  the  Promissory  Note,  or (b) to  the  replacement  of  Collateral  or
rebuilding  of the Alabama  Project,  with any  remaining  balance to be paid to
Debtor.

                  Section 6.  Other Insurance.  Nothing  shall  prohibit Secured
Party or any other Additional  Insured from insuring the Alabama Project and the
Collateral at its own expense.

                  Section  7.  Application   of   Payments   from   Governmental

authority or other entity with respect to condemnation,  confiscation,  theft or
seizure  of,  or  requisition  of  title  to or use of the  Alabama  Project  or
Collateral,  shall be applied  either (a) in reduction  of Debtor's  obligations

payable;  and such failure  continues for thirty (30) days after written  notice
from the  Secured  Party to the Debtor  thereof;  provided,  however,  that such
failure  to pay shall not  constitute  an Event of  Default  at any time that it
results  from at any time the  Secured  Party (or any  affiliate  thereof) is in
default of its obligations under other Transaction Document,  the withholding or
application  in set off of any amount  otherwise due and payable with respect to
the  Obligations by the Debtor against amounts owed by the Secured Party (or any

thereof) is in default of its obligations under other Transaction Document,  the
withholding or  application  in set off of any amount  otherwise due and payable
with  respect to the  Obligations  by the  Debtor  against  amounts  owed by the

Agreement Documents or the Promissory Note.

obligated  to,  without  further  notice or demand on the  Debtor,  and  without
releasing  the Debtor  from any of the  Obligations,  perform  or  observe  such
agreement  on behalf and in the name,  place and stead of the Debtor (or, at the
Secured  Party's  option,  in the Secured Party's own name) and take any and all
other actions which the Secured Party may deem necessary to cure or correct such
failure, including the payment of taxes, the satisfaction of security interests,
Liens,   attachments  or  encumbrances,   the  procurement  and  maintenance  of
insurance, and the procurement of repairs or transportation,  subject,  however,
to the terms of the other  Transaction  Documents.  The Secured Party shall have
the right to appear in and defend any action or proceeding  purporting to affect
the security interest or the rights or powers of the Secured Party hereunder and
in the Purchase  Agreement  Documents.  The Debtor shall  indemnify and hold the
Secured Party harmless from and against, any and all losses, liabilities, claims
and causes of action  arising  from or in  connection  with the Secured  Party's
actions  in the stead of the  Debtor  and the  Debtor  shall  thereupon  pay the
Secured  Party on demand the amount of all moneys  expended  and all  reasonable
costs and expenses (including  attorneys' fees) incurred by the Secured Party in
connection  with or as a result of the Secured  Party's  performing or observing
such agreements or taking such action,  together with interest  thereon from the
date  expended  or incurred by the  Secured  Party at twelve  percent  (12%) per
annum.

                  Section 12. Secured Party's Costs and Expenses. In addition to
other  amounts  payable  hereunder,  the  Debtor  will  (whether  or  not  legal
proceedings are commenced) pay to the Secured Party,  on demand,  all reasonable
costs  and  expenses  (including  attorneys'  fees and legal  expenses)  paid or
incurred by the Secured Party in connection with an Event of Default,  including
any suit to collect the Obligations.

                  Section 13. Purchase Money Equipment Security Interest. Debtor
and Secured Party agree and stipulate  that this is a "purchase  money  security
interest" as such term is used in the Code.


                  Section 14. Successors; Governing Law. This Agreement shall be
binding upon and inure to the benefit of the Debtor, the Secured Party and their
respective successors and permitted assigns. This Agreement shall be governed by
the substantive  laws of the State of Utah,  without giving effect to any choice
of law or conflict of law  provisions or rules that would cause the  application
of laws of any  jurisdiction  other than the State of Utah.  Unless the  context
otherwise requires,  all terms used herein which are defined in Articles 1 and 9
of the Uniform  Commercial  Code, as in effect in the State of Utah,  shall have
the meanings  therein stated.  If any provision or application of this Agreement
is  held  unlawful  or  unenforceable   in  any  respect,   such  illegality  or
unenforceability  shall not affect other provisions or applications which can be
given  effect,  and this  Agreement  shall be  construed  as if the  unlawful or
unenforceable  provision  or  application  had never  been  contained  herein or

                                       9


prescribed  hereby.  All  representations  and  warranties   contained  in  this
Agreement  shall  survive  the  execution,  delivery  and  performance  of  this
Agreement and the creation and payment of the Obligations.

                  Section 15.  Notices.  All  notices to  the Secured  Party and
the Debtor shall be given in accordance with the notice  provisions set forth in
the Purchase Agreement.

                  Section 16.  Further Assurances. The Debtor  will  defend  the
security  interest of the Secured  Party  against  all  Persons,  other than the
Secured  Party,  at its own  expense  and from time to time  shall  execute  and
deliver to the Secured Party,  and file all such  instruments  and take all such
actions as the Secured  Party may  reasonably  request in order to preserve  and
protect such security interest,  to effectuate the purpose of this Agreement and
the Purchase Agreement Documents or to carry out the terms hereof, including the
execution and filing of financing  statements or continuation  statements  under
the Code. The Debtor hereby  authorizes the Secured Party to file this Agreement
or any such financing statements or continuation  statements under the Code with
respect to the Collateral with any appropriate  governmental  office in order to
preserve,  protect,  perfect or continue the  perfection of any and all security
interests granted or created hereby.

                  Section 17.  Miscellaneous.  This  Agreement  can  be  waived,
modified,  amended or terminated, and the security interest of the Secured Party
can be released,  only  explicitly in a writing  signed by the Secured Party and
the Debtor.  A waiver signed by the Secured Party shall be effective only in the
specific  instance and for the specific purpose given.  Mere delay or failure to
act shall not preclude the exercise or enforcement of any of the Secured Party's
rights or  remedies.  All rights and  remedies  of the  Secured  Party  shall be
cumulative  and may be  exercised  singularly  or  concurrently,  at the Secured
Party's option,  and the exercise or enforcement of any one such right or remedy
shall neither be a condition to nor bar the exercise or enforcement of any other
right or remedy.  The  Secured  Party shall not be  obligated  to realize on the
Collateral  at all or in any  particular  manner or order,  or to apply any cash
proceeds therefrom in any particular order of application.

                  Section 18. Power of Attorney. The Debtor  hereby  irrevocably
appoints  the  Secured  Party as its true and lawful  attorney-in-fact  upon the
occurrence of an Event of Default with full power,  in the name of the Debtor or
otherwise,  for the purpose of (i) taking any action that the Secured  Party may
deem  necessary or appropriate  to preserve,  protect,  perfect and continue the
perfection of the Secured Party's security interest in the Collateral;  and (ii)
enabling  the  Secured  Party  to  sell,  assign,  transfer  or  dispose  of the
Collateral, including, without limitation, executing and delivering all bills of
sale,  assignments  and other  instruments  as the  Secured  Party may  consider
necessary  or  appropriate,  with full power of  substitution,  upon an Event of
Default.

                  Section 19.  Consent  to  Jurisdiction  and Venue.  Debtor and
Secured  Party  consent to  personal  jurisdiction,  waive any  objection  as to
jurisdiction  or venue and agree not to  assert  any  defenses  based on lack of

                                       10


jurisdiction or venue, in the County of Salt Lake,  Utah.  Service of process on
Debtor  or  Secured  Party in any  action  arising  out of or  relating  to this
Agreement  shall be effective  if mailed to such party at the address  listed in
the Purchase Agreement.

                  Section 20. Mutual  Waiver  of  Jury  Trial.  BECAUSE DISPUTES
ARISING IN CONNECTION WITH COMPLEX  FINANCIAL  TRANSACTIONS ARE MOST QUICKLY AND
ECONOMICALLY  RESOLVED BY AN EXPERIENCED  AND EXPERT PERSON AND THE PARTIES WISH
APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION  RULES), THE
PARTIES  DESIRE  THAT  THEIR  DISPUTES  BE  RESOLVED  BY A JUDGE  APPLYING  SUCH
APPLICABLE LAWS.  THEREFORE,  TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF
THE JUDICIAL SYSTEM,  THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY
ACTION,  SUIT OR PROCEEDING  BROUGHT TO ENFORCE OR DEFEND ANY RIGHTS OR REMEDIES
UNDER THIS AGREEMENT.

                  Section 21.  Pronouns  and Certain  Other Terms.  All pronouns
(and any variation) will be deemed to refer to the masculine,  feminine, neuter,
singular or plural as the  identity of the Person may  require.  The words "and"
and "or" will include the conjunctive and disjunctive,  as the context requires.
The word  "include"  and  derivatives  of that word are used in an  illustrative
sense and not a limiting sense unless specifically indicated.

                                       11


                  IN WITNESS WHEREOF,  the parties have caused this Agreement to
be executed as of the date set forth above.
