prevailing at the  commencement of the lease term shall be altered,  modified or
enlarged so as to cause the method of  taxation  to be  changed,  in whole or in
part, so that in  substitution  for the real estate taxes now assessed there may
be, in whole or in part, a capital levy or other  imposition  based on the value
of the Leased Premises,  or the rents received therefrom,  or some other form of
assessment  based in whole or in part on some other  valuation  of the  Lessor's
real property  comprising  the demised  Premises,  then and in such event,  such

                               GENERAL PROVISIONS

condition  of the Leased  Premises,  and has received the same in good order and
repair,  and agrees; a. To use these Premises for reasonable use as set forth in
Section  1.17,  which  do not  materially  damage  the  Leased  Premises.  b. To
surrender  possession of these  Premises at the expiration of this lease without

     2.3 Repairs, Maintenance and Alterations by Lessee. The Lessee has promised

such  liens or claims  and  against  all  attorneys'  fees and  other  costs and
expenses growing out of or incurred by reason or on account of any such liens or
claims.  Should Lessee fail to fully discharge any such lien or claim within ten

lien or claim, and Lessee shall immediately reimburse Lessor for such payment.

during the term herein specified  unless caused by Lessor,  an agent or employee
of Lessor, or Lessor's successor.

     2.10 Right of Re-Entry.  Lessor shall have the right, by itself or agent or
with others, to enter the Premises at reasonable hours to examine or exhibit the
Premises,  or to make such repairs and alterations as shall be deemed  necessary
for the safety and preservation of the building, to inspect and examine, to post
such notice as Lessor may deem  necessary  to protect  Lessor  against Loss from
liens of laborers,  materialmen or others,  and for the purpose of permitting or
facilitating Lessor's performance of its obligations hereunder, or for any other
reasonable purpose which does not materially  diminish Lessee's enjoyment or use
of the Leased Premises.

     Lessee expressly waives any claim for damages,  including loss of business,
resulting  from  Lessor's  entry,  from the  erecting  of  scaffolding  or other
structures to facilitate repairs,  or from Lessor's other reasonable  activities
for the purpose of  altering,  improving,  or repairing  the Leased  Premises in
conformity herewith.

     2.11  Assignment or  Sub-Letting.  No assignment,  sublease or sale of this

reason for withholding consent, it shall be determined by arbitration.

by Lessor, any and all sub-leases shall be responsible Lessees, and Lessee shall
not be relieved of any liability hereunder by Lessee's  assignment,  vacation or
subletting thereof.



     It is agreed that one of the conditions moving Lessor to make this lease is
the personal  confidence reposed by it in Lessee,  combined with the belief that
Lessee will be a Lessee and  occupant  satisfactory  to Lessor.  Nothing  herein
shall prevent the Lessor from assigning its interest under this lease, provided,
however,  that any assignee shall be subject to the same  obligations and duties
as the original Lessor.

such sum or sums paid by Lessor  for the  account  of Lessee and the cost of any
such work,  together  with  interest  thereon at the rate of eighteen  (18%) per
annum from the date of payment.

occupy or lease the whole or any part thereof for and on account of Lessee,  and
upon such terms and conditions, and for such rent as Lessor may deem proper, and
to collect  said rent any other rent that may  thereafter  become  payable,  and
apply the same toward the amount due or hereafter to become due from Lessee, and
on account of such expense of such  subletting  and other  damages  sustained by
Lessor;  and should such  rental be less than that  herein  agreed to be paid by
Lessee,  Lessee agrees to pay such  deficiency to Lessor in advance on the first
(1st))  day of each  month  and to pay to the  Lessor  forthwith,  upon any such
re-letting,  the cost and expenses Lessor may incur by reason thereof and should
such rental be more than that herein  agreed to be paid by Lessee,  Lessor shall
hold said sum interest free to be applied to future damages;  c. The right, even
though it may have re-let the  Premises,  hereafter to elect to  terminate  this
lease and all of the  rights to  Lessee  in or to the  Premises.  d. Any and all
rights as set forth in the Deed of Trust on the Black  Canyon  Mica Mine,  which
Deed of Trust is referred to in Section 1.7 hereinabove.



     As used in this lease with respect to the Premises,  the terms "vacate" and
"abandoned" shall be deemed to include, without limiting the broadest meaning of
those terms, the failure of Lessee to be open for business in the Premises for a
period of fifteen (15) consecutive business days, unless such failure is excused
or permitted under the expressed terms of this lease.  Should Lessor ever re-let
the Premises under the provisions of  Sub-paragraph  (b) above,  "it may execute
any such lease in its own name,  and the Lessee  therein named shall be under no
obligation,  whatsoever,  to see to the  application  by  landlord  of any  rent
collected  by  Lessor  from such  Lessee,  nor  shall  Lessee  have any right or
authority  whatever to collect any rent from such  Lessee.  Lessor  shall not be
deemed to have  terminated  this  lease or the  liability  of Lessee to pay rent
thereafter  to  accrue,  or  Lessee's  liability  for  damages  under  any other
provisions  hereof by any such reentry or by any action in unlawful  detainer or
otherwise  to obtain  possession  of the  Premises,  unless  Lessor  shall  have
notified  Lessee in  writing  that it has so elected to  terminate  this  Lease.
Nothing herein  contained shall be construed as obligating  Lessor to re-let the
whole  or any  part  of the  Premises.  In the  event  of any  entry  or  taking
possession  of the Premises as aforesaid,  Lessor shall have the right,  but not
the  obligation,  to remove  therefrom all or any part of the personal  property
located therein and may pace the same as storage at the public  warehouse at the
expense and risk of the owner or owners thereof.

     In the event of Lessee's default and Lessor's retaking of possession of the
Premises,  whether this lease is terminated  by Lessor or not,  Lessee agrees to
pay  to  Lessor,  as an  additional  item  of  damages,  the  cost  of  repairs,
alterations,  redecorating,  leasing  commissions  and Lessor's  other  expenses
incurred in re-letting Premises to a new Lessee.

     The  remedies  given to Lessor in this  provision  shall be in addition and
supplemental  to all other  rights or remedies  which  Lessor may have under the
laws of the State of Arizona then enforced. Any breach of Lessee of any covenant
or obligation to be performed by it hereunder shall be and shall be deemed to be
material  and shall give Lessor the right,  in addition to all other  rights and
remedies  reserved or granted to Lessor  hereunder,  to terminate this lease and
retake  possession  in the  Premises.  The waiver by Lessor of any breach of any
term,  covenant or condition herein contained shall not be deemed to be a waiver
of such term,  covenant or condition or any subsequent breach of the same of any
term, covenant or condition herein contained.  The subsequent acceptance of rent
hereunder  by the  Lessor  shall not be deemed to be a waiver of any  proceeding
breach of Lessee of any term,  covenant or condition  of this lease,  other than
the failure to Lessee to pay the particular  rental sum accepted,  regardless of
Lessor's  knowledge of such proceeding  breach at the time of acceptance of such
rent. No covenant,  term or condition of this lease shall be deemed to have been
waived by Lessor, unless such waiver be in writing signed by Lessor.

     2.17 Court Action,  Attorney's  Fees and Costs.  If, upon failure of either
party to comply with any of the covenants,  conditions,  rules or regulations of
and in this lease, suit or arbitration  should be brought for damages on account
thereof,  or to enforce  the payment of rent  herein  stipulated,  or to recover
possession of the Premises, or to enforce any provision hereof, the losing party
agrees to pay to the prevailing party reasonable costs and expenses  incurred in
prosecuting  these  suits  or  arbitration,   as  determined  by  the  court  or
arbitrator,  including  attorneys'  fees  and  the  value  of  time  lost by the
prevailing  party or any of its employees in preparing for or  participating  in
any arbitration or litigation in connection therewith.  Interest shall accrue on
that  award at the  maximum  legal  rate on all  monetary  amounts  awarded  for
principal,  interest,  attorneys'  fees and all other amounts,  from the date of
that award until paid.

     2.18 Operating Costs. All operating  expenses of Lessee of whatever nature,
are the sole obligation of Lessee.

     2.19  Landlord's  Lien.  Upon the  termination  of this lease in any of the
manners herein  provided,  or upon default by Lessee under any of the provisions
hereof,  Lessor may enter the Leased  Premises  and remove any and all  personal
property of Lessee and may retain possession of such personal property until all
charges of any kind, including rent, storage or damages, shall be paid in full.



     It is further agreed that the Lessor shall have a lien on all buildings and
improvements  based on the  demised  premises  by  Lessee  and on all  fixtures,
furniture and inventory kept or used on the premises  including any replacements
therefore,  whether  such  property is exempt from  execution  or not, to secure
payment of all rents,  and all other sums becoming due to Lessor or others under
the provisions of this lease and to secure  performance of all other obligations
of Lessee hereunder. Such lien shall be a first lien superior to any encumbrance
created by Lessee on the property or interest  covered by this provision.  It is
further agreed that this provision shall  constitute a security  agreement under
the provisions of the Arizona  Commercial Code and it is further agreed that the
parties  shall  execute a financing  statement  for filing with the  appropriate
governmental  authorities  and  shall  execute  any  and all  other  instruments
necessary to perfect the lien rights of Lessor hereunder.

     2.20  Abandonment.  If Lessee  shall be in  default  in the  payment of the
rental and shall  vacate or abandon the Premises or any part thereof (an absence
of Lessee  therefrom  for a period of fifteen (15) days after such default shall
be considered such an abandonment thereof, Lessor may, it is so elects, re-enter
the Leased  Premises and remove the contents and take  possession  of the Leased
Premises and re-let the same or any part  thereof,  at such rental and upon such
terms and conditions as it may deem proper and apply the proceeds thereof,  less
the  expenses,  including the usual  agent's  commission  so incurred;  upon the
amount due from Lessor hereunder and Lessee shall be liable for any deficiency.

     If Lessor shall take  possession of the Premises and relate the same,  such
reletting  shall not operate as a  termination  of this lease  unless  Lessor so
elects,  such  election to be evidenced by written  notice to Lessee;  nor shall
such  action by Lessor  operate as a waiver of any other  rights or  remedies of
Lessor hereunder.

     2.21  Holdover.  If Lessee shall  holdover after the expiration of the term
hereof,  with the consent of Lessor,  express or implied,  such tenancy shall be
from month to month only,  and not a renewal  hereof,  and Lessee  agrees to pay
rent at 125% rate of the  lease  rent in effect  prior to the  holdover  and all
other charges as hereinabove provided,  and also to comply with all covenants of
this lease for the time Lessee holds over. If Lessee shall hold over without the
consent of Lessor,  express or implied,  then Lessee  shall be construed to be a
Lessee at sufferance at doubt the rent herein provided prorated by the day until
possession is returned to Lessor.  If Lessee shall hold over with the consent of
Lessor,  Lessee shall be entitled to possession until Lessor has given Lessee 30
days notice that such month to month  tenancy  shall be  terminated;  otherwise,
notice is only required as hereinafter provided as notice of default.

     2.22 Destruction of Leased Premises.

     a. In the event the Premises be damaged by fire or other perils  covered by
a fire and  extended  coverage  insurance  which pays  Lessor  replacement  cost
thereof the Lessor shall:

     (1) Within ninety (90) days  thereafter  and subject to obtaining  licenses
permits and  approvals,  commence  repair,  reconstruction  and  restoration  of
Premises and prosecute the same  diligently to  completion,  in which event this
lease shall continue in full force and effect; or

     (2) In the event of a partial or total  destruction of the Premises  during
the last two (2)  years of the term  hereof,  Lessor  shall  have the  option to
terminate  this lease upon giving  notice to Lessee of exercise  thereof  within
sixty (60) days after such  destruction.  For  purposes of this  paragraph  (ii)
"partial  destruction"  shall be deemed a destruction  to the extent of at least
thirty-three  and one-third  percent (33 1/3%) of the Premises as of the date of
destruction.

     b. In the event the Premises shall be damages to any extent whatsoever as a
result of any flood, earthquake, active war, nuclear reaction, nuclear radiation
or radio  active  contamination,  or from any other  casualty not covered by the
fire and extended coverage insurance which would pay Lessor the replacement cost
of the damaged Premises, Lessor may, within ninety (90) days, following the date
of such  damage  (plus such  additional  time as may be  required  to obtain the
necessary permits, licenses and approvals),  commence repair,  reconstruction or
restoration of the Premises and to prosecute the same  diligently to completion,
in which  event this lease shall  continue  in full force and effect,  or within
said ninety (90) day period elect not to so repair,  reconstruct, or restore the
Premises,  in which event this lease shall cease and  terminate.  In either such
event,  Lessor  shall give Lessee a notice of its  intention  within said ninety
(90) day period.

     c. In the event of any  reconstruction  or  restoration  of the Premises by
Lessor in accordance with the provisions of this lease,  such  reconstruction or
restoration  shall  restore the Premises to  substantially  their  condition and
immediately  prior to the  occurrence  of the casualty  (excluding  merchandise,
trade  fixtures,  furnishings,  wall  coverings,  carpeting or floor  coverings,
drapes,  equipment  and items of  personal  property  of Lessee  located  on the
Premises).  However, such reconstruction and restoration by Lessor shall be only
to the extent of Lessor's  real  property  interest  with the exception of lease
hold improvements. Lessee shall be responsible for the repair and restoration of
all of Lessee's lease hold  improvements,  trade fixtures and other property in,
on or about the Premises.



     d. Upon any  termination  in this lease under any of the provisions of this
article entitled "Destruction of Leased Premises",  each party shall be released
thereby  without  further  obligation  to the other  party  coincident  with the
surrender of possession  of the Premises to Lessor,  except for items which have
theretofore accrued and are then unpaid.

     e. In the  event  of  repair,  reconstruction  and  restoration  as  herein
provided,  the Base Rent shall  abate  proportionately  in relation to the floor
area of the Premises  rendered  untenable by such casualty  commencing  from the
date  of  destruction   and  continuing   during  the  period  of  such  repair,
reconstruction  or  restoration.  Lessee  shall  continue  the  operation of its
business  in the  Premises,  during  any such  period to the  extent  reasonably
practicable  from  the  stand  point of  prudent  business  management;  and the
obligation of Lessee hereunder to pay Additional Rent (i.e. taxes and insurance)
shall  remain in full force and  effect.  Lessee  shall not be  entitled  to any
compensation  and  damages  from  Lessor for loss in the use of the whole or any
part of the Premises,  and Lessee's  personal  property or any  inconvenience or
annoyance occasioned by such damage, repair, reconstruction or restoration.

     2.23  Removal of trade  fixtures.  Lessee  shall  have the right,  upon the
expiration of the term of this lease,  or at any time during such term if Lessee
shall not be in default,  to remove from the Leased  Premises  all  fixtures and
equipment  placed  thereon by Lessee,  even  though  permanently  affixed to the
Leased Premises;  provided,  however,  that Lessee, in effecting removal,  shall
restore  the  Leased  Premises  to a good,  safe,  sound,  orderly  and  sightly
condition.

     2.24 Eminent  Domain.  If the Leased  Premises or any part thereof shall be
taken by eminent  domain,  which taking shall render the remainder of the Leased
Premises  unsuitable for occupancy and use by Lessee for the purpose intended by
Lessee,  then and in such event,  the full current amount payable to the date of
taking, or the prorated amount of that month's rent to the taking, shall be paid
to Lessor, and this lease shall terminate as of the date of taking.

     If only a part of the Leased Premises shall be taken by eminent domain, and
such taking shall not unduly  interfere with the occupancy and use of the Leased
Premises for the purpose  intended by Lessee,  then and in such event,  the full
amount  payable for and upon such taking  shall be paid to Lessor,  and from and
after the date of such taking, only a just and proportionate part of the rentals
for the Leased Premises hereby reserved shall be paid by Lessee.

     Lessee  shall  have the  right to claim  and  recover  from the  condemning
authority,  but not from Lessor,  such compensation as may be separately awarded
or  recoverable by Lessee in Lessee's own right on account of any and all damage
to  Lessee's  leasehold  interest,   to  Lessee's  business  by  reason  of  the
condemnation, and for or on account of any cost or loss to which Lessee might be
put  in  removing   Lessee's   merchandise,   furniture,   fixtures,   leasehold
improvements and equipment.

     2.25  Subordination.  If Lessor shall desire at any time,  and from time to
time to secure a loan or loans upon the  security of the Leased  Premises,  then
and in such event,  Lessee hereby agrees to make and enter into a  subordination
agreement or agreements  with any  responsible  lending agency that Lessor shall
designate,  wherein and whereby Lessee's rights,  titles and interests in and to
the Leased Premises are subordinated to the line of any mortgage or mortgages to
be made,  executed  and  delivered by Lessor as security for that loan or loans;
provided,   however,   that  the  subordination  shall  be  upon  the  following
conditions:  a. The  execution of the  subordination  agreement or agreements by
Lessor shall impose no personal  liability  whatsoever upon Lessee.  b. Any such
mortgage or mortgages  shall provide that the  mortgagee  shall agree to give to
Lessee all notices  required to be given to Lessor as mortgagor  under the terms
and conditions of those mortgages, or any loan agreement or agreements, or under
the laws of the state where the Leased Premises are situated. c. The mortgage or
mortgages  shall further provide that in the event of any default on the part of
Lessor under the terms and conditions thereof or the obligation secured,  Lessee
may, at its own election,  cure such default,  and any amount expended by Lessee
in so doing  shall be paid by Lessor to  Lessee,  with  interest  thereon at the
maximum  legal  rate  per  annum  from  the time or  times  any  expenditure  or
expenditures  for such purpose  were made,  upon demand by Lessee  therefor.  d.
Lessor  shall  indemnify  and hold  harmless  the Lessee of and from any and all
liability,  cost or expense to which  Lessee may be put by reason of the failure
of Lessor to keep and perform any of the covenants and  agreements set forth and
contained in such mortgage or mortgages and the obligations thereby secured.

     2.26 Sale by Lessor.  In the event of a sale or conveyance by Lessor of all
or part of the Leased  Premises,  the same shall operate to release  Lessor from
any  future  liability  upon any of the  covenants  or  conditions,  express  or
implied, herein contained in favor of Lessee, and in such event Lessee agrees to
look solely to the  responsibility of the successor in interest of Lessor in and
to this lease.  This lease  shall not be  affected by any such sale,  and Lessee
agrees to attorney to the purchaser or assignee.

     2.27  Applicable  Law.  This lease shall be subject to and  governed by the
laws of the  State of  Arizona,  regardless  of the fact that one or more of the
parties now is or may become a resident of a different state.

     2.28 Assignment of Personal Property Warranties. Provision omitted.

     2.29 Prorations.  If any prorations are required to be made under the terms
of this  lease,  the  prorations  shall be made as of the first day of the lease
term.

     2.30  Environmental  Provisions.  Lessee  represents and warrants to Lessor
that Lessee will not generate,  store,  treat, use,  release,  or dispose of any
hazardous  materials  on or about the Leased  Premises or the Project  except in
compliance with all environmental laws and any additional  conditions imposed by
Landlord. Lessee will not release or dispose of any hazardous materials in or on
the Leased  Premises or the Project  without  the  express  written  approval of
Lessor.  Lessee shall obtain,  comply with and provide Lessor with copies of all
permits  required in connection with the generation,  storage,  treatment,  use,
release, or disposal of any hazardous materials.

Lessee shall not install nor permit to be installed on or in the Leased Premises
any  substance  containing  asbestos  and  determined  to be  hazardous  by  any
governmental  authority or any friable  asbestos.  If any such  substance or any
friable asbestos is determined to be in or on the Leased Premises as a result of
the  actions  of  Lessee,  Lessee  shall  promptly  comply  with any  applicable
environmental  laws (which may or may not require  removal of the  material)  at
Lessee's expense.



     In the event  Lessee  fails to perform  any of its  obligations  under this
Article  within thirty (30) days after the giving to Lessee by Lessor of written
notice  of such  failure,  or within a  reasonable  period of time not to exceed
ninety (90) days after the giving to Lessee by Lessor of written  notice of such
failure  if, due to the nature of such  failure,  such  failure  cannot be cured
within a 30-day period but is otherwise  susceptible to cure within a reasonable
period of time not exceeding  ninety (90) days, or within a short period of time
if  prescribed  by  any  environmental  law,  then,  after  expiration  of  such
applicable  period of time,  Landlord  may enter  upon the Leased  Premises  and
remove  or cause to be  removed  such  hazardous  material  or  otherwise  cause
compliance with any applicable environmental law, provided, however, that Lessor
may enter  upon the  Leased  Premises  and  remove or cause to be  removed  such
hazardous   material  or  otherwise   cause   compliance   with  any  applicable
environmental  law upon written  notice to Lessee but prior to the expiration of
the applicable time period,  if Lessor  determines that such action is necessary
prior to the expiration of the applicable  time period (i) for the  preservation
or safety of the Leased Premises,  or other persons, (ii) to avoid suspension of
a necessary  service in, or with respect to, the Leased  Premises  (iii) for the
preservation  of the lien and grant of any deed of trust  granted  to any lender
with respect to the Leased  Premises or the priority of such lien and grant,  or
(iv) to assure the continued  operation of the Leased Premises.  The cost of any
such removal or  compliance  shall be  immediately  due to Lessor upon demand as
additional rent.

     Lessee  shall,  at  Lessee's  own  expense,  comply  with all  present  and
hereinafter  enacted  environmental  laws affecting  Lessee's  activities on the
Leased Premises.  Lessee shall keep the Leased Premises free of any lien imposed
pursuant to any  environmental  laws,  except for any liens being  contested  by
Lessee  in good  faith and at its own  expense  by  appropriate  action or legal
proceedings,  provided  that such  actions  or  proceedings  operate  to prevent
collection  thereunder or realization  thereon and the sale or forfeiture of the
Leased  Premises  to satisfy the same,  and  provided  further  that during such
contest Lessee shall,  at the option of Landlord,  provide  security  reasonably
satisfactory  to Landlord  assuring  the  discharge of Lessee's  obligations  in
respect  of the  lien  being  contested  and any  additional  interest,  charge,
penalty, or expense arising from or incurred as a result of such contest.

hazardous  materials  put there by Lessee or its agents which  either  Lessee or
Lessor is required by law to remove.  In addition,  Lessee shall be  responsible
for restoring the Leased  Premises to their condition  immediately  prior to the

change or has the  potential to change  Lessee's or  Landlord's  obligations  or

for, from and against any and all loss, damage, obligation,  penalty, liability,
litigation, demand, defense, judgment, suit, proceeding, cost, disbursement, and
expense (including,  but not limited to, reasonable investigation,  remediation,

or order of any  government  or  judicial  entity,  and  from  and  against  any
contractors,  employees,  and  invitees  on the Leased  Premises  or the Project
during the Term of this lease.  Lessee's  obligations and liabilities under this
paragraph  shall  continue  after the expiration or termination of this Lease so
long as Landlord bears any liability or  responsibility  under the environmental
laws for any action that occurred on the Leased  Premises of the Project  during
the Term of this Lease. Lessee's failure to abide by the terms of this paragraph
shall be restrainable by injunction.

     3.13  Interlineations  and Initials.  The parties recognize that because of
the exigencies of the modern world, the mechanics of drafting the convenience of
the parties,  and the economy of costs,  they may have in their own  handwriting
made minor changes in this  instrument.  These minor changes have been initialed
by all parties, if any changes have been made, fore and aft of the change on all
originals to prevent any  extension of  alteration  of that change by any of the
parties or others.  Unless otherwise indicated by the placement of a date beside
the change,  these  changes were  intended by the parties to have occurred as of
the effective date of this  instrument.  Any  interlineated  changes made by the
parties after the effective  date of this  instrument  shall be initialed by all
parties,  dated,  and have the date itself initialed fore and aft by all parties
to this instrument.

     3.14  Execution.  All parties  named in the  caption as parties  shall sign

copies  of this  instrument.  Furthermore,  all  documents  such  as  schedules,
exhibits and like  documents  which are expressly  incorporated  herein shall be
initialed by all parties and either exchanged or attached to the originals which
are given to any party named on the caption page of this instrument.

     3.15 Acknowledgement. The notary public who has acknowledged the signatures
of the various parties as designated in the acknowledgements hereto certify that
this  instrument was  acknowledged by the signing party before the notary on the
date of the notarization. If the instrument was subscribed by any of the parties
in a representative capacity, then the notary ascertained that the signing party
signed for the  principal  named by that party and in the capacity in which that
party indicated he/she signed.
