                  2.1. The Improvements. Developer shall expand its Tempe Fab II
Facility  in two phases by adding  35,000  square  feet of clean room along with
equipment for wafer manufacturing and related support systems (the "Expansion").

                  2.2. Fees and Taxes. Developer shall pay all required fees for

August 1997 and completion of Phase Two in February 1998.

                  2.4. Presently Anticipated Cost and Employment.  The Expansion
will be  constructed  at a total cost of  approximately  $137  million  and will
employ  approximately  150  additional  workers at an expected  average  wage of
approximately $50,000 per year.

         3. CITY APPROVAL PROCESSES.

                  3.1.  Scope of  Development.  Developer  and City  shall  work
together using best efforts  throughout the legally required planning process to
expeditiously obtain approvals for the Expansion.

                  3.2.  Expansion  Approval.   The  approval  by  City  of  this
Agreement constitutes affirmative  representation by City, on which Developer is
entitled to rely,  that  Developer,  notwithstanding  subsequent  changes of the
zoning or land use controls  applicable  to the Property  after the date of this
Agreement,  or after the date of any amendments to this Agreement,  or zoning on
the Property  are  approved,  (1) shall be  authorized  to  implement  the uses,
density  and  intensity,  set forth for the  Expansion  and (2) will be accorded
through the legally required planning process the approvals reasonably necessary
to permit  Developer to proceed with and  implement  the proposed  improvements,
including any  amendments  thereto,  subject to City's  customary  standards for
review and approval of site plans and architectural  plans,  including expedited
design  review.  Developer  and City shall  work  together  using  best  efforts
throughout  the  planning  and  permitting  stages to resolve any City  comments
regarding  the  proposed  

development,  provided, however, that if Developer believes at any stage that it
has reached an impasse regarding any issue with City's staff, such dispute shall
be resolved in accordance with the dispute resolution provisions of Section 3.8.

                  3.3.  Diligence in Review and Process.  In connection with the
proposed  development  and  the  issuance  of  building  permits,   construction
inspections,  and the issuance of the Certificates of Occupancy,  City agrees to
the following processing times:  processing times for building plan review shall
be in accordance  with standards for commercial  additions/alterations  (fifteen
(15)  working days  turnaround  time for initial  review,  five (5) working days
turnaround time for resubmittals).  Turnaround time for design review is two (2)
weeks provided complete application materials are supplied two (2) weeks or more
prior to a regularly scheduled Design Review Board meeting.

                  3.4.  Appointment  of  Representative.  In order  to  expedite
decisions  by City,  City agrees to  designate  a single plan check  engineer to
review all building plans. This will assure consistency of review and efficiency
through knowledge of prior submittals.  The initial plan check engineer shall be
Tom  Tahmassian.  (Note that the plan check engineer for mechanical  electrical,
and plumbing  permit may be  different.)  The Developer  shall advise the City's
representative  at the building  counter when submitting  application  that this
agreement  is in effect and that plans  should be given to the  designated  plan
check engineer.

                  3.5.  Expeditious  Permit  Process.  City  will  use its  best
efforts to expeditiously review permits, plan reviews, inspections.

                  3.6 Certificates of Occupancy.  City agrees that promptly upon
completion  of  Expansion  and at such  time  as a  building  is in  substantial
compliance with applicable City Code and ordinance,  City will provide Developer
(or  the  owner  of such  building)  with a  Certificate  of  Occupancy  for the
Expansion.  If City fails or refuses to provide a  Certificate  of Occupancy for
any  portion of the  Expansion  when  requested,  City  shall,  within  four (4)
business days after written request from Developer,  provide Developer a written
statement  indicating  in  adequate  detail  how  they  failed  to  satisfy  the
conditions  for issuance of the  Certificate  of Occupancy  and what measures or
acts City requires  before City will issue the  Certificate  of Occupancy.  City
shall not withhold approval without good and substantial reason.

                  3.7  Subdivision  Requirements.  The parties  acknowledge  and
agree that in  connection  with the  development  of the  Property  in phases or
otherwise,  as long as the  Property  remains  in the  ownership  of  Developer,
Developer will not need to further  subdivide the Property,  and that no further
subdivision  approvals  are  required  by  City.  In the  event,  however,  that
Developer does transfer  title of a portion of the Property to new entity,  City
agrees that it will  promptly  process any and all approvals of all requests for
subdivision  approval in conjunction with the Property,  and further agrees that
it will approve any subdivision  request reasonably  required in connection with
the development of the Property, subject to the Property as subdivided complying
with applicable zoning and health and safety ordinances.

                  3.8  Resolution  of Disputes.  City and  Developer  agree that
Developer  must  be able to  proceed  rapidly  with  the  proposed  development.
Accordingly,  the parties agree that if at any time  Developer  believes that an
impasse has been  reached  with City staff on any issue  affecting  the proposed
development or issuance of a certificate of occupancy,  Developer shall have the
right to  immediately  appeal to the Deputy City Manager for  Development  for a
decision pursuant to this Section 3.8. If the issue on which an impasse has been
reached  where a final  decision  can be reached by City staff,  the Deputy City
Manager for  Development  shall give  Developer  a final  decision no later than
eight (8) business days after the request for such decision is made. If issue on
which an impasse has been reached is one where a final  decision  requires  City
Council action, the Deputy City Manager for Development shall be responsible for
scheduling  a City  Council  hearing  on the issue no later than three (3) weeks
after the request.  Both parties agree to continue to use reasonable  good faith
efforts  to  resolve  any  impasse  pending  any  such  appeal.   The  Developer
acknowledges  that City may not be able to comply with this  schedule  requiring
City  Council  hearings  during the months of December  and  August.  City will,
however,  use its best  efforts in complying as  completely  as possible  during
these months.

         4. CITY PROVISION OF INCREASED SEWER CAPACITY.

                  4.1. Sewer Capacity.  Developer has  represented  that it will
increase its discharge to the City's  sanitary  sewer system by 380,000  gallons
per day  (average)  for the  proposed  Expansion.  The  Public  Works  Director,
pursuant to the  authority  granted to her by Tempe City Code Section  27-213(E)
has determined that the Developer is a Significant  Industrial User (hereinafter
"SIU") that is  significantly  increasing  its discharge to the City's  sanitary
sewer  system.  The Director has  determined  that the amount of  $1,536,000  is
necessary to be assessed as an additional sewer development fee to reimburse the
City for the cost associated with providing the sewer collection system capacity
and waste water  treatment  plant  capacity  calculated or estimated for the SIU
considering  average daily and peak capacity needs and  abilities.  The City has
represented to the Developer that it has the ability to accommodate the proposed
discharge  to the  City's  sanitary  sewer  system.  No  connection  to the City
sanitary sewer system  necessary to accommodate  the additional  380,000 gallons
per day  (average)  will be  permitted  or allowed  until the  additional  sewer
development  fee of $1,536,000  is paid.  This fee shall be due and payable upon
issuance of the  Certificate  of  Occupancy  for Phase II but in no event latter
than April 1, 1998.

                  4.2.   Up-Front  Fees.   Developer   shall  pay  to  City  the
nonrefundable  sum of One Million  Five  Hundred  Thirty Six Thousand and no/100
Dollars  ($1,536,000) (the "Up Front Fee") for the additional sewer capacity set
forth in Section 4.1.

         5. FOREIGN TRADE ZONE TAXATION.

                  5.1. Foreign Trade Subzone Application. The City shall use its
best efforts to cause City of Phoenix to sponsor an  application  to the Foreign
Trade Zones Board of the U.S.  Commerce  Department  ("Board") for issuance of a
grant of authority for a special purpose foreign-trade subzone ("Subzone") to be
operated  by  Developer  covering  the  structures  comprising  the Tempe Fab II
Facility (Exhibit C) pursuant to the following procedure:

                           5.1.1. Application. Developer shall prepare a Subzone
                  application ("Application") at its sole cost and expense.

                           5.1.2.  Subzone  Operations  Agreement.   Prior  to
                  requesting  activation of the Subzone, the City of Phoenix and
                  Developer  shall execute a Foreign  Trade  Subzone  Operations
                  Agreement (the "Operations Agreement") permitting Developer to
                  utilize the Subzone as a foreign-trade subzone, subject to the
                  terms  and  conditions  of the  Operations  Agreement,  for an
                  initial  period  equal to the maximum  period  allowed by law,
                  thereafter  to be  automatically  extended  from  year to year
                  unless  terminated  by  the  terms  thereof.   The  Operations
                  Agreement  shall  acknowledge the provisions of Section 5.1.3.
                  It is specifically  understood that in the event Foreign Trade
                  Subzone status is not achieved as provided in Section 5.2, and
                  upon  payment  of the  sewer  development  fee  set  forth  in
                  paragraphs 4.1 and 4.2 above, Developer shall have an absolute
                  right to unilaterally  cancel this Agreement and in such event
                  there  shall be no further  obligation  or  liability  to City
                  under this Agreement.

                           5.1.3.  City Standing.  Developer  acknowledges  that
                  breach of its property tax class limitations set forth in this
                  Article 5 would be detrimental to the public interest and that
                  Tempe would be a party  "directly  affected"  (as that term is
                  used in 15 CFR Part  400).  Developer  will not  object to the
                  City's  standing  before the Foreign  Trade Zones Board or any
                  other  administrative  body or  court,  in the  event the City
                  seeks to show that  Developer's  use of the  subzone is not in
                  the public  interest and, as a consequence  thereof,  seeks to
                  terminate  the grant of the  subzone,  or  otherwise  limit or
                  terminate Developer's use of the subzone.

                           5.1.4.  City  Concurrence.  The City  will  execute a
                  letter of  concurrence  prior to  activation of the Subzone by
                  the U.S.  Customs  Service upon  receipt of a written  request
                  therefor from Developer,  and shall use all reasonable efforts
                  to assist in achieving the Foreign  Trade  Subzone  status and
                  the Operations  Agreement  with the City of Phoenix,  provided
                  that no Developer  Performance Default shall have occurred and
                  be continuing.

                  5.2.  Tax   Classifications.   Arizona  Revised  Statutes  ss.
42-162(A)(8)(b)  provides  that  all  real  and  personal  property  within  the
boundaries  of a Foreign  Trade Zone or subzone  shall be  classified as Class 8
property  for taxation  ("Class  8");  provided,  however,  such  classification
applies  only to the area that is  activated  for Foreign  Trade Zone use by the
Port Director of the U.S. Customs Service,  pursuant to 19 C.F.R.  146.6, A.R.S.
ss.  42-162.01,  and  the  procedures  of  the  Maricopa  County  Assessor  (the
"Assessor")  require that the owner notify the Assessor that a  reclassification
of property to Class 8 should be made.

                  5.3.  Foreign Trade Zone Costs.  Developer shall pay all costs
charged by the City of Phoenix for the  formation  and  oversight of the special
purpose foreign trade subzone of the Phoenix Foreign Trade Zone No. 75.

         6. CONDITIONS TO DEVELOPER'S OBLIGATIONS. Developer's obligations under
this Agreement are subject to  satisfaction  of all of the following  conditions
precedent:

                  6.1.  Zoning.  The  City  represents  and  warrants  that  the
Property has been  properly  classified  for I-2 zoning  pursuant to the City of
Tempe zoning ordinance.  City further agrees that this zoning is vested and that
no other action is necessary  in order to vest the zoning.  City further  agrees
that it will take no action to remove or change  the  zoning  without  the prior
written consent of the Property owner.

                  6.2. Foreign Trade Zone Status.  Developer anticipates that by
June 30, 1998, the United States Department of Commerce will have issued a grant
of authority for the ("Subzone") to be operated by Developer within the Property
pursuant to procedure set forth in Section 5.1. However, City and Developer both
understand and agree that Developer has no influence over the speed at which the
United States Department of Commerce processes said grant of authority.

                  6.3. Approval of Plans and Specifications. The City shall have
given Developer all necessary  permits and approvals for the construction of the
Expansion.

                  6.4.  Property Tax  Classification.  Developer  shall  receive
written acknowledgment from the Maricopa County Assessor's office that all those
portions of the Tempe Fab II Facility  and all  personal  property  used therein
specified in Section 5.1 have been and will continue to be classified as Class 8
property.

         7. REPRESENTATIONS.

                  7.1.  Developer  Representations.   Developer  represents  and

         8. CANCELLATION OF THE EXPANSION.

                  8.1.  For  Business   Reasons.   Provided  the  upfront  sewer
development  fee has  been  paid,  Developer  reserves  the  right  in its  sole
discretion to cancel,  delay, or abandon  construction of all or any part of the

unilaterally cancel this agreement for any reasonable business reason.

                  8.2.  Due to Impasse or Delay in Approval  Process.  Developer
reserves  the  right  in its  sole  discretion  to  cancel,  delay,  or  abandon
construction  of all or any part of the Expansion if an impasse or  unacceptable
delay is reached on any matter  relating to a City  approval  under  Section 3.8
hereof.

                  8.3.  For Loss of Class 8 Property  Classification.  Developer

repeals or  adversely  modifies the Class 8  assessment  ratio.  In the event of
abandonment  of  construction  of all or any part of the  expansion  and/or  the

         9. DEFAULTS AND REMEDIES.

                  9.1. Events Constituting Developer Default. Developer shall be

otherwise available to it.

                  9.3.  Events of Default by City. City shall be deemed to be in

including,  without  limitation,  (i) the  failure  to  issue a  Certificate  of
Occupancy where Developer has complied with its obligations for issuance of such
Certificate;  or (ii) the failure to provide other approvals as required herein,

         10.  DISPUTE  RESOLUTION.  The  parties  will  attempt in good faith to
resolve any controversy or claim arising out of or relating to this  Development
Agreement through the process set forth in Section 3.8 and through  negotiation.
If, however, a matter has not been resolved within the time set forth in Section

by  arbitration  in accordance  with the then  prevailing  rules for  commercial
arbitration of the American Arbitration Association. Notwithstanding such rules,

         11. UNCONTROLLABLE  FORCES.  Neither party shall be considered to be in
default in the performance of any of its obligations under this Agreement (other
than  obligations  of such  party to pay costs and  expenses)  when a failure of
performance  shall be due to an uncontrollable  force. The term  "uncontrollable
force"  shall be any cause beyond the control of the party  affected,  including
but not  restricted  to failure of or threat of  failure of  facilities,  flood,
earthquake,   tornado,  storm,  fire,  lightning,  epidemic,  war,  riot,  civil
disturbance  or  disobedience,   labor  dispute,  labor  or  material  shortage,

by or failure to obtain  the  necessary  authorizations  or  approvals  from any
governmental agency or authority, which by exercise of due diligence it shall be
unable to overcome. Nothing contained herein shall be construed so as to require
a party to settle any strike or labor  dispute in which it may be involved.  Any
party rendered unable to fulfill any of its obligations  under this agreement by
reason of any uncontrollable force shall give prompt written notice of such fact
to the other party and shall  exercise due  diligence  to remove such  inability
with all reasonable dispatch.
