                              DEVELOPMENT AGREEMENT


         This  Development  Agreement  ("Agreement") is made as of the 29 day of
August, 1997 by and between the City of Chandler,  Arizona, an Arizona municipal
corporation  (which together with any successor public body or officer hereafter
designated  by or pursuant to law, is hereafter  called  "City"),  and Microchip
Technology Inc., a Delaware  corporation (which together with its successors and
assigns, is hereafter called "Developer").

                                    RECITALS:
                                    ---------

         A. The parties hereto acknowledge that this Agreement is intended to be
and  constitutes a  "Development  Agreement"  as authorized  pursuant to Arizona
Revised Statutes,  ss. 9-500.05,  and that, in accordance  therewith,  a copy of
this  Development  Agreement shall be recorded with the Maricopa County Recorder
no later than ten (10) days after entering into this Agreement to give notice to
all persons of its existence and of the parties' intent that the burdens of this
Agreement are binding on, and the benefits of this Agreement shall inure to, the
City and Developer and their respective successors-in-interest and assigns.

         B.  Developer is the owner of  approximately  80 acres of real property
depicted on Exhibit  A-1  attached  hereto and more  particularly  described  on
Exhibit  A-2  attached  hereto  (the  "Property"),  including  and  adjacent  to
Developer's corporate headquarters facility at 2355 W. Chandler Boulevard.

         C. In  furtherance  of the City's goal of continued  development of the
Property  as  provided  for in the General  Plan,  Developer  intends to further
develop the  Property  as an  electronics  manufacturing  facility by adding two
additional  fabrication  buildings,  an administrative  building,  and ancillary
structures and equipment (collectively the "Facility").

         D. City desires to obtain those public  benefits which will accrue from
the further  development of the Property in accordance with City's General Plan,
including,  but not  limited  to  creation  of  jobs,  stimulation  of  economic
development in City,  construction  of  infrastructure  improvements  within the
public right-of-way  adjacent to the Property,  and generation of additional tax
revenues to City.

         E.  Pursuant  to  Arizona  Revised  Statutes  ss.  9-500.11,   City  is
authorized and empowered to make economic  development  expenditures of the type
expressly provided for in this Agreement.

         NOW,  THEREFORE,  in consideration  of the mutual  agreements set forth
herein, it is understood and agreed by the parties hereto as follows:

         1.  RECITALS.  The  recitals  set forth above are  acknowledged  by the
parties to be true and correct and are incorporated herein by this reference.

         2. ON-SITE IMPROVEMENTS BY DEVELOPER.

                  2.1. The  Facility.  Developer  shall  construct and equip the
Facility  in general  conformity  with the  preliminary  site  plans  previously
submitted to the City and in accordance  with final site plans to be approved by
the  City in  general  conformity  with the  approved  preliminary  site  plans,
including buildings, parking lots, landscaping, signs, and all on-site utilities
including but not limited to the on-site  roads built to present city  standards
for private roads. Developer shall also construct at its expense water and sewer
mains within the Property  boundaries which are necessary to serve the Property,
as approved by the City  Engineer.  The Facility will include  construction  of:
"Fab 3," an approximate 115,000 square foot manufacturing  facility,  containing
approximately  50,000  square feet of clean  room,  equipment  for 8-inch  wafer
manufacturing,   and  ancillary  space  for   manufacturing   support   systems;
construction of a four story, approximately 200,000 square foot office building;
and, at the sole option of Developer, conversion of one existing building into a
wafer testing facility.

                  2.2. Fees and Taxes. Developer shall pay all required fees for
plan  check,  building  permit,  engineering  review,  recording,  impact/system
development, and all local sales taxes applicable to construction of the on-site
improvements described in Section 2.1.

                  2.3. Presently  Anticipated Timing of Construction.  Developer
shall Commence Construction of: (a) the Fab 3 building on or before the later of
June 15, 1999, or the date Developer is granted  foreign trade subzone status as
required in section 7 and (b) the office building on or before July 1, 1998, or,
in either case, such later date as business  conditions may reasonably  require.
Once  construction  has  begun  on  any  such  facility,   Developer  shall  use
reasonable,  good faith  efforts to complete such  construction  in a continuous
manner. For purposes of this Agreement, "Commence Construction" or "Commencement
of Construction" shall be the date of commencement of work on foundation for the
applicable  improvements  while  securing all permits  required under the City's
Construction  Code from the City's  Building  Department,  as  evidenced  by the
City's first  inspection and approval for foundation work.  Developer  presently
intends for  construction  of Fab 3 to be completed by within  twenty-five  (25)
months of the date of the  Commencement  of  Construction,  but no commitment to
that effect is given.
                                       2

                  2.4. Presently  Anticipated Cost and Employment.  The Facility
will be constructed at a total cost of  approximately  $450 million and, at full
capacity, will employ approximately 1,000 workers at an expected average wage of
approximately $49,000 per year.

         3. TRAFFIC  STUDY.  Developer  has prepared and submitted to the City a
traffic impact analysis to determine  improvements needed to maintain acceptable
levels  of  service  through  the  year  2010 at  level  of  service  "D."  City
acknowledges  that the traffic  study  provided by Developer is acceptable to it
and will  form the basis  for the  traffic  improvements  provided  for  herein,
subject to the current proposal for construction of only one Fab unit.

         4. DEDICATION OF CERTAIN  PROPERTY BY DEVELOPER.  Developer shall at no
cost to the City  cause the  following  described  parcels to be  dedicated  and
conveyed to the City by assignment,  special  warranty deed, or other instrument
legally  sufficient  to convey and  dedicate  to the City all  right,  title and
interest  of  Developer  in and to such  parcels,  free and clear of all  liens,
encumbrances, covenants, conditions and restrictions:

                  4.1. Traffic Right of Way. Right-of-way no more extensive than
necessary  to  permit  the   construction   of  required   street  and  off-site
improvements specified in the traffic impact analysis referred to in Section 3.

                  4.2.  Well and Storage  Facilities.  If City  chooses to drill
wells or locate a storage  facility  on the  Property  in order to  satisfy  its
obligations under Section 6.4,  Developer shall dedicate up to five (5) acres of
the  Property  for water well and/or  storage  facilities.  The exact size,  and
location,  of such dedication shall be as mutually agreed by City and Developer,
and shall be  configured  so as to minimize the land  requirement  to the extent
reasonably  possible  and  to  accommodate  construction  of the  Facilities  as
planned. Developer shall make the land described herein available to City within
sixty (60) days after the  Developer  provides  City with the notice  that it is
proceeding  with Fab 3.  Developer  shall  provide  up to five (5) acres if City
needs the land for both the well and storage.  If City needs the land for a well
only, one (1) acre shall be provided.

         5. CITY APPROVAL PROCESSES.

                  5.1.  Scope of  Development.  Developer's  Facility  plans set
forth a  conceptual  land use and density on the  Property.  Developer  and City
shall work together using best efforts  throughout the legally required planning
process to obtain expedited approvals.

                  5.2. Facility 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 this
Property are approved,  (1) shall be  authorized to implement the uses,  density
and intensity,  set forth for the Facility, 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  
                                       3

standards  for  review  and  approval  of site  plans and  architectural  plans,
including  expedited  design  review  pursuant  to  Sections  5.3  through  5.7.
Developer  and City  shall  work  together  using best  efforts  throughout  the
planning 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 5.8.

                  5.3.  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
accelerate all approvals,  inspections and permitting  processes to the greatest
extent  possible.  City will not impose any  unusual  or  extraordinary  plan or
design review  requirements.  The fast-tracking and priority  scheduling program
will take into  account,  among other  things,  the  magnitude  and scope of the
Facility,  mixed use and phasing  consideration,  construction  document review,
permitting, inspection, and City approval matters.

                  5.4.  Appointment  of  Representative.  In order  to  expedite
decisions by City, City agrees to designate a representative of City to act as a
liaison between City and Developer,  and between City's various  departments and
Developer.  City's  representative shall be available at all reasonable times to
serve as such  liaison in order to ensure  expedited  review and approval of all
permits, plans, specifications,  plats, and/or any other development submittals,
project drawing  revisions,  or approvals for the Property and the Facility,  it
being the intention of this  paragraph to provide  Developer with one individual
utilized consistently as City's principal  representative.  Developer shall also
designate a Developer  representative  who shall serve as a liaison  between the
Developer  and City.  The initial  City  representative  shall be the Planning &
Development Director and the initial Developer  representatives  shall be Robert
J. Lloyd, or other persons designated by Developer.

                  5.5. Expedited Building Permit Process with on-site Inspector.
City will provide at its sole expense an expedited  building permit process with
plan review,  inspection,  and approval  conducted at the Property by an on-site
inspector  empowered by City to make decisions  without further review processes
to meet the need of Developer's  expansion.  The on-site review process shall be
provided  for  a  maximum  of  twenty-five  (25)  months  from  commencement  of
construction  on Fab 3. If Developer  wishes the building  permit  process to be
expedited further than it is expedited by one on-site inspector,  Developer will
pay the cost of additional on-site personnel.

                  5.6. Certificates of Occupancy. City agrees that promptly upon
completion of each building of the Facility and at such time as a building is in
compliance  with  applicable  City  Codes  and  ordinances,  City  will  provide
Developer (or the owner of such  building)  with a Certificate  of Occupancy for
such  building.  Upon  substantial  compliance  with  applicable  City codes and
ordinances,  City  will  provide  Developer  with  a  temporary  certificate  of
occupancy for the limited purpose of testing  equipment within the building.  If
City fails or refuses to provide a  Certificate  of Occupancy for any portion of
the Facility  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
                                       4

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.

                  5.7.  Subdivision  Requirements.  The parties  acknowledge and
agree that in connection  with the  development of the Property,  developer will
need to combine some of the parcels which currently comprise the Property.  City
and Developer  agree to mutually  cooperate  with each other to effectuate  this
combining  of parcels  which will most likely  result in a two lot  subdivision.
City agrees that it will expedite any and all such  approvals and further agrees
that it will approve any subdivision  request reasonably required in conjunction
with  the  development  of  the  Property,  subject  only  to  the  Property  as
subdivided, complying with applicable zoning, health and safety ordinances.

                  5.8.   Resolution  of  Disputes.   City  and  Developer  agree
Developer  must  be able to  proceed  rapidly  with  the  proposed  development.
Accordingly,  an expedited  City review process is essential.  Accordingly,  the
parties  agree that if at any time  Developer  believes that an impasse has been
reached with City or an unreasonable delay affecting the proposed development or
issuance  of a  certificate  of  occupancy,  Developer  shall  have the right to
immediately appeal to the City representative for an expedited decision pursuant
to this paragraph. If the issue on which an impasse or delay has been reached is
an  issue on which a final  decision  can be  reached  by City  staff,  the City
representative  shall give  Developer a final  decision  within two (2) business
days after the request for an expedited  decision is made. If the issue on which
an impasse  or delay has been  reached  is one where a  decision  requires  City
Council action,  the City  representative  shall be responsible for scheduling a
City  Council  hearing on the issue which  hearing  shall be held within two (2)
weeks after the request for an expedited  decision is made by  Developer.  If an
impasse or delay  still  exists  thirty  (30)  calendar  days after  Developer's
request for an expedited decision,  Developer shall proceed under Article 15 and
may  immediately  cease all activities in connection  with  construction  of the
Facility.  Developer  acknowledges  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.

         6. CITY PROVISION OF TRANSPORTATION  AND TRAFFIC  IMPROVEMENTS;  WATER,
            AND SEWER.

                  6.1. Transportation  Improvements.  Upon Developer's giving of
the notice  specified in Section 6.6, City shall design and  construct  four (4)
enumerated  street  improvement  projects  identified  on  Exhibit  "B"  hereto.
Developer  shall be  responsible  for no more than  $238,275  (based on  present
estimates) of the cost of constructing these  transportation  improvements.  The
City  shall be  responsible  for all  costs of the  transportation  improvements
beyond $238,275  (based on present  estimates).  The foregoing  figures shall be
adjusted  proportionately based on the final construction costs using a ratio of
$238,275  (Developer) to $696,000 total.  Such  construction  shall include at a
minimum the following items:  subgrade preparation and pregrading;  paving; curb
and gutter on all permanent edges of the streets; driveways; bus bay(s); parkway
grading;  adjustment of manholes;  adjustment of water valves; 
                                       5

survey  monuments;  catch basins;  storm sewer laterals;  street lights,  street
light trenching; and landscaping and irrigation systems.

                         Concurrently  with,  or as soon as  possible  following
Developer's  notice  under  Section 6.6,  City shall  provide  Developer  with a
projected time line for solicitation of bids for such improvements,  awarding of
contracts and  commencement of  construction,  provided that subject to the City
having  received notice 25 months prior to the estimated  completion  date, such
time line shall in no event extend the estimated  completion  dates set forth in
Section  2.3,  inasmuch  as such  improvements  are  necessary  for  the  timely
completion and  commencement of operation of Fab 3 and its related  improvements
and Developer will be materially  adversely  affected by any delay in completion
of such improvements.  City shall periodically,  and in no event less frequently
than every 60 days,  provide Developer with a progress report in respect of such
improvements  as well as current  information  concerning  the expected costs of
constructing the same.

                         City  shall use its best  efforts  to  obtain  Economic
Strength  Fund  grants  from the State of Arizona in the  approximate  amount of
$696,000 to cover the cost of off-site  improvements  described in this Article,
and Developer shall cooperate with City is seeking those grants. Developer shall
provide $25,113 toward the match funds required for the Economic  Strength Funds
and City shall provide all the balance of required  match funds.  If such grants
are not  received,  the City shall still be obligated to  construct,  subject to
Developer  contribution  pursuant to paragraph 6.1, the improvements referred to
in this  Article 6. If such grants are  received,  they shall all be used by the
City to construct the transportation  improvements described in section 6.1, and
the traffic  improvements  described in section 6.2. The first $238,279 received
shall be credit against, and shall be deemed to satisfy,  Developer's obligation
to bear a portion of the cost of the  transportation  improvements  described in
this section.

                  6.2.  Construction Water Supply. The City shall provide access
to an existing fire hydrant  adjacent to the Property along Chandler  Boulevard,
Ellis Street or Frye Road on or before the date Developer  commences grading and
devegetation  activities at the Property, for Fab 3. Developer shall establish a
construction  water  account  with the  City  Development  Services  Department,
install the  requisite  fire hydrant  meter,  and pay all charges for water used
during construction in accordance with City Code.

                  6.3.  Operations  Water Supply.  City shall provide  Developer
with  a one  (1)  million  gallon  per  day  additional  groundwater  supply  of
Acceptable Quality (the "Additional Water Supply") through one well to which the
Facility  shall have  priority  use to the full extent of the  Additional  Water
Supply,  and,  when the  Additional  Water  Supply well is  temporarily  down or
otherwise  inoperable,  through  additional well(s) (the "Backup Water Supply").
Ground water shall be of Acceptable Quality only if the following  standards are
met: (1) total  organic  carbon  ("TOC")  content shall be less than or equal to
three (3) parts per  million;  and (2) the  ground  water  shall meet the City's
presently existing primary drinking water standard.

                  6.4.  Additional  Water Supply.  The  Additional  Water Supply
shall be made available to Developer  prior to its completion of Fab 3. The City
will  buy  wells  from a third  
                                       6

party or drill on the  Property  any new wells  required  to fulfill  the City's
obligation  under this  Section 6.4. If the City chooses to purchase an existing
well from a third party, the City shall construct at its sole expense all lines,
pumps, and other  facilities  required to deliver the Additional Water Supply to
the Property lines,  including but not limited to any water mains or other lines
in the public right of way of groundwater of acceptable  quality. In all events,
City shall reserve in its water supply system at all times after commencement of
construction of Fab 3, the amount of capacity required to deliver the Additional
Water Supply  described in this Section 6. The Additional  Water Supply shall be
at the City's sole expense except:  (a) the buy-in fees provided in Section 6.7;
and (b) the  payments for water  actually  delivered  as  hereinafter  provided.
Developer will be  responsible  for on-site water main  construction.  Developer
will pay for  water  delivered  by the City to the  Property  at rates  not less
favorable than the rates then being charged by the City to any other  industrial
user. No take or pay agreement will be required from  Developer.  In all events,
City shall reserve in its water supply one and one-half  (1-1/2) million gallons
per day of groundwater  either through the Additional Water Supply or the Backup
Water Supply hereinafter described.

                         6.4.1.  Backup  Water  Supply.  The City shall make the
Backup Water Supply  through  ground water of  Acceptable  Quality  available to
Developer  prior to its completion of Fab 3. The City's  provision of the Backup
Water Supply shall be on the following additional terms and conditions. The City
shall use its best efforts to locate,  drill,  and equip,  an additional  backup
dedicated  well on the Property,  and shall  consult  fully with  Developer on a
regular  basis and fully  inform  Developer on the  feasibility  of drilling the
Backup well on the Property and any and all other options that are available for
location of the Backup well. Developer shall have the highest priority to use of
the  groundwater  from said well to the extent  necessary  for the Backup  Water
Supply.  If the well is so located on the Property by the City, the Backup Water
Supply shall be at the City's sole expense except:  (a) the buy-in fees provided
in section 6.7; and (b) the payments for water actually delivered as hereinafter
provided; and (c) Developer's connection costs.

                         6.4.2.    Off-Property   Backup   Water   Supply.   If,
notwithstanding  its best efforts  under  Section  6.4.1,  the City is unable to
locate the Backup Water Supply on the Property,  then the City shall purchase an
existing  well located off the  Property  from a third party or drill a new well
located off the  Property.  The City shall  consult  fully with  Developer  on a
regular  basis and fully  inform  Developer of all options that are possible for
location of the Backup well off-Property. The City shall use its best efforts to
locate the  off-property  Backup well so that the actual cost of construction of
transmission  lines and  delivery  facilities  to the  Property  does not exceed
$1,000,000.  If, after consultation,  City and Developer mutually agree that the
Backup well cannot be located so that the total cost of the  transmission  lines
and delivery system to the Property does not exceed  $1,000,000,  then Developer
shall notify the City either:  (1) that the Developer will agree to increase the
reimbursement  amount  provided  below  to  the  full  amount  of  the  cost  of
transmission lines and delivery facilities; or (2) that the Developer will waive
the  requirement  for a Backup well and will accept for the Backup  Water Supply
only,  water from the City's public water system which meets the City's  present
primary  drinking  water  standard.  City  agrees  to  proceed  on the  basis of
whichever of the two elections Developer makes. Developer shall have the highest
priority to use of the groundwater from said well to
                                       7

the extent  necessary for the Backup Water Supply.  In the case of any such well
located  off the  Property,  the City shall  construct  at its sole  expense all
lines,  pumps, and other facilities  required to deliver the Backup Water Supply
to the  Property  line,  including  but not  limited to any water mains or other
lines in the public  right of way.  If it is  necessary  for the City to proceed
under this Section 6.4.2,  then Developer and City shall work together to arrive
at a mutually  agreeable  arrangement  under which Developer shall reimburse the
City for the actual cost of construction of such transmission lines and delivery
facilities,  but not to exceed  $1,000,000  (unless  pursuant  to an election by
Developer  as set forth  above),  either in a lump sum cash  reimbursement  or a
surcharge on the Developer's price for delivered water over a period of time, as
the parties may determine by mutual agreement.

                         6.4.3.   On-Site   Construction.   Developer   will  be
responsible for all on-site water main construction.

                         6.4.4. Payment.  Developer will pay for water delivered
by the City to the  Property  at rates not less  favorable  than the rates  then
being charged by the City to any other industrial user,  except as may otherwise
be  agreed  pursuant  to the last  sentence  of  Section  6.4.2.  No take or pay
agreement will be required from Developer.

                         6.4.5.  Total Water Supply 1.5 Million Gallons Per Day.
City  acknowledges that Developer plans to continue the operation of its current
original  facility  for five or more years and that the water  requirements  set
forth in this  paragraph 6 reference  an  additional  water  commitment  for the
Facility. Therefore, while Developer operates both the existing facility and the
Facility,  it will  require a total  combined  water  commitment  of 1.5 million
gallons per day. City agrees to provide Developer with a total water capacity of
1.5 million gallons per day from groundwater of Acceptable  Quality at such time
and while both the current facility and the Facility are operating.

                  6.5.  Sewer.  City  shall  provide  Developer  with an 800,000
gallons per day  additional  sewer capacity for Fab 3. City shall reserve in its
sewer disposal system at all times after completion of construction of Fab 3 the
amount of capacity  required to deliver the additional sewer capacity  described
in the first sentence of this Section 6.5.  Trunk line  facilities are currently
in place and appear to be adequate,  but City shall be obligated to augment such
facilities if they prove to be inadequate,  by  constructing at its sole expense
all mains,  lines, and other  facilities  necessary to accept or accommodate the
additional 800,000 gallons per day sewer flow or effluent from Fab 3 and related
improvements.  No up-front or other additional fees or costs shall be imposed on
Developer  with respect to the  additional  sewer  capacity  provided for herein
except the buy-in fees set forth in section 6.7.  Developer  will be responsible
for on-site sewer main  construction  and  connection to the city line. The City
shall be responsible for all costs necessary to bring the sewer line adjacent to
the  portion  of the  Property  where the first  construction  will take  place.
Developer  shall be responsible for connection to the sewer line in Ellis Street
and for all on-site  construction  costs. The additional sewer capacity shall be
at the City's sole  expense  except the  payments for normal sewer usage fees as
hereinafter  provided.  Developer  will pay for  ongoing  sewage  service to the
Property at rates not less  favorable  than 
                                       8

the rates then being charged by the City to any other  industrial  user. No take
or pay agreement will be required from Developer.

                  6.6.  Construction  Timing.  Developer shall give City written
notice at least thirty (30) days before commencement of construction of Fab 3 of
Developer's  intention  to commence  construction  and of the  Developer's  best
estimate  of when such  construction  will be  completed.  City shall  cause all
improvements  described in this Article 6 required for Phase One of the Facility
to be  constructed  at least two months  prior to the  projected  completion  of
construction  of Fab 3.  City  shall  not  commence  construction  of any of the
improvements  described  in this  Article  6  necessary  for  Fab 3 until  after
Developer has given the notice specified in this section 6.6. Concurrently with,
or as soon as possible following Developer's notice under this Section 6.6, City
shall provide  Developer with a projected time line for solicitation of bids for
all  improvements  required under  Sections 6.1, 6.3, 6.4, and 6.5,  awarding of
contracts therefor,  and commencement of construction,  provided that subject to
the City having  received  notice 25 months  prior to the  estimated  completion
date, such time line shall in no event extend the estimated completion dates set
forth in Section 2.3, inasmuch as such improvements are necessary for the timely
completion and  commencement of operation of Fab 3 and its related  improvements
and Developer will be materially  adversely  affected by any delay in completion
of such improvements.  City shall periodically,  and in no event less frequently
than every 60 days,  provide Developer with a progress report in respect of such
improvements  as well as current  information  concerning  the expected costs of
constructing the same.

                  6.7.  Buy-in and  Development  Fees.  Developer  agrees to pay
water and sewer buy-in fees and  development  fees for the Facility.  Based upon
the preliminary  plans  submitted to the City, and projected  number and size of
meters shown on Exhibit C, it is  estimated  that these Fab 3 charges will total
$255,146. When the final plans for this project are submitted to the City, these
fees might be adjusted;  but they shall not  materially  exceed the estimate set
forth above unless the project area increases or the number or size of requested
meters  change.  Developer  acknowledges  that there is the potential for yearly
increases  in fees  for all  users  of an  applicable  size  meter  and any such
increase for all users shall not be considered a material increase.

         7. FOREIGN TRADE ZONE TAXATION

                  7.1. 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  within the  Property  pursuant  to the  following
procedure:

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

                         7.1.2.   Subzone   Operations   Agreement.   Prior   to
requesting  activation of the Subzone,  the City of Phoenix and Developer  shall
execute  a  Foreign-Trade   Subzone   
                                       9

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 7.1.3.  The  Operations  Agreement  shall
require  Developer to remain in compliance with the property tax  classification
limitations set forth in Section 7.3. It is specifically  understood that in the
event Federal Trade Subzone status is not achieved as provided in Sections 9 and
12.5,  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  other than  payment of City's  costs as  provided in
Section 13.1.

                         7.1.3.  City  Standing.   Developer  acknowledges  that
breach of its property tax class  limitations  set forth in this Article 7 would
be  detrimental  to the  public  interest  and  that  Chandler  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.

                         7.1.4. 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  (which request may
occur before  commencement of construction or before  completion of construction
of the Facility),  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.

                  7.2.  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.

                  7.3.  Developer  Limitation.  Notwithstanding  that the entire
Property and Facility shall receive Foreign Trade Zone status,  Developer agrees
that only the  following  portions of the Property and  Facility  shall  receive
Class 8 property tax classification: (a) The Fab 3 Building, all land underlying
that  building  and the  parking  and  landscaped  areas  associated  with  that
building,  and all personal property used in connection with that building;  and
(b) the  presently  existing  building if and when it is converted  into a wafer
testing  facility,  all land underlying it and the parking and landscaped  areas
associated  with it,  and all  personal  property  used in  connection  with it.
Exhibit D hereto  designates the  approximate  locations of the Class 8 land and
buildings within the Property.
                                       10

                  7.4. Minimum Property Tax Amounts.

                         7.4.1.  From and after Year 1.  Developer has projected
that the value of all real and personal property comprising the Property and the
Facility  will  be far in  excess  of  normal  industrial  property.  Therefore,
Developer  agrees that if in the following  years, the total City property taxes
on all real and personal  property  comprising  the Property and the Facility is
less than the minimum amount indicated,  Developer will pay the shortfall amount
to the City.

                         Year              Minimum City Property Tax Amount
                         ----              --------------------------------

                         Year 1:                No guaranteed minimum.
                         Years 2-6:             $225,000
                         Years 7-8:             $200,000
                         Years 9-11:            $150,000

For purposes of this Section  7.4,  "Year 1" shall mean the first full  calendar
year that Fab 3 is fabricating products. In any year in which there is a fifteen
percent (15%) reduction to Developer's segment of the electronics  manufacturing
market,  Developer may provide  reasonable  evidence of such to the City Council
and Developer shall be relieved of the requirements of this section 7.4.

                         7.4.2.  Prior  to Year  1.  Because  activation  of the
Foreign  Trade  Subzone  may  occur  prior  to  commencement  or  completion  of
construction  of the Facility,  Developer  agrees that if, solely as a result of
activation of the Foreign Trade Subzone, the City property taxes due for any tax
year prior to Year 1 on all real and personal  property  comprising the Property
and the  Facility  are less  than what the City  property  taxes on all real and
personal  property  comprising the Property and the Facility would have been but
for early  activation of the Foreign Trade Subzone,  Developer shall pay to City
the shortfall amount.

                  7.5.  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 discussed
later in the Agreement.  Developer's written approval shall be required for City
to enter into an agreement with City of Phoenix regarding any such costs.

         8. STATE FUNDING.  Developer and City may be eligible for state funding
for various aspects of the Facility and its operations. Developer and City shall
use their best efforts to cooperate in identifying all possible sources of state
funding,  including  but not limited to training  grants and  economic  strength
grants,  and in applying for and obtaining the benefit of such state funding for
the Facility and its operations.

         9. CONDITIONS TO DEVELOPER'S OBLIGATIONS. Developer's obligations under
this Agreement are subject to  satisfaction  of all of the following  conditions
precedent:
                                       11

                  9.1.  Zoning.  The  City  represents  and  warrants  that  the
Property has been  properly  classified  for I-1 zoning  pursuant to the City of
Chandler  zoning  ordinance.  City agrees that no other  action is  necessary in
order to place the I-1 zoning on the Property.  City further agrees that it will
take no action to remove or change the I-1 zoning within five (5) years and that
any action to remove or change the zoning  after that  period  will only be done
for valid,  reasonable land use reasons. City further agrees that upon Developer
starting construction of Fab 3, the I-1 zoning on the Property shall be vested.

                  9.2. Foreign Trade Zone Status.  The United States  Department
of Commerce  shall,  no later than  December  31,  1999,  have issued a grant of
authority for a special purpose foreign-trade subzone ("Subzone") to be operated
by Developer within the Property pursuant to procedure set forth in Section 7.1.

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

                  9.4.  Property  Tax   Classification.   Developer  shall  have
received  an  unqualified  written   acknowledgment  from  the  Maricopa  County
Assessor's office that all those portions of the Property, the Facility, and all
personal  property  used on the Property  specified in Section 7.3 have been and
will continue to be classified as Class 8 property.

         10.  CONDITIONS TO CITY'S  OBLIGATIONS.  City's  obligations under this
Agreement  are  subject  to the  conditions  precedent  that the  United  States
Department  of  Commerce  shall,  in a timely  fashion,  have  issued a grant of
authority for a special purpose foreign-trade subzone ("Subzone") to be operated
by Developer within the Site pursuant to procedure set forth in Section 7.1.

         11. REPRESENTATIONS

                  11.1.  Developer  Representations.  Developer  represents  and
warrants that (a) it is a corporation  duly organized,  validly  existing and in
good  standing  under  the laws of the  State of  Delaware,  (b) its  execution,

brought to contest the validity of this Development Agreement and shall not seek
from the City any payments, contributions,  costs or attorneys' fees incurred in
such defense.

                  11.2. City  Representations.  City represents and warrants (a)
that its execution,  delivery and performance of this Development  Agreement has

codes of City, (b) that subject to a court's equitable powers,  this Development
Agreement  is  enforceable  in  accordance  with its terms,  (c) that City shall
execute all  documents  and take all action  necessary to implement  and enforce
this  Development  Agreement,  (d)  that  the  representations  made  by City to

                                       12

Development  Agreement are truthful to the best of its knowledge and belief, and
(e) that City shall vigorously defend any action brought to contest the validity
of  this  Development   Agreement  and  shall  not  seek  from  Developer,   any
contributions, payments, costs, or attorneys fees incurred in such defense.

         12. CANCELLATION OF THE FACILITY.

                  12.1. For Business  Reasons.  Developer  reserves the right in
its sole discretion to cancel, delay, or abandon construction of all or any part
of the Facility for business  reasons as determined  by Developer.  In the event
Developer  exercises its rights under this Section 12.1 to delay construction of
all or part of the Facility,  Developer  agrees to reimburse City for City Costs
as provided in Article 13.

                  12.2. 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  Facility if an impasse or  unacceptable
delay is reached on any matter  relating to a City  approval  under  Section 5.8
hereof.  In the event  Developer  exercises  its rights under this Section 12.2,
Developer shall reimburse City for City Costs as provided in Article 13.

                  12.3.   Failure  to  Approve  Final  Site  Development  Plans.
Developer reserves the right to cancel, delay, or abandon construction of all or
any part of the Facility if City fails to provide  reasonable  approval of final
plans and  specifications  by the dates  necessary  to  permit  commencement  of
construction  at the times specified in Section 2.3, or any action by City which
would  otherwise  preclude  Developer from realizing the land use or intensities
specified  for the  Facility;  provided,  however,  that  nothing  herein  shall
preclude  City from the  reasonable  exercise of its normal  review and approval
processes as agreed to be modified herein;  and provided further that City shall
not act in an arbitrary or capricious  manner. In the event Developer  exercises
its rights under this Section 12.3, Developer shall have no further liability to
City under this  Agreement,  including  but not  limited  to any  obligation  to
reimburse City Costs as provided in Article 13.

                  12.4. For City's Performance  Default.  Developer reserves the
right  to  cancel,  delay,  or  abandon  construction  of all or any part of the
Facility if a City Performance  Default (as hereinafter  defined) occurs. In the
event  Developer  exercises its rights under this Section 12.4,  Developer shall
have no  further  liability  to City  under this  Agreement,  including  but not
limited to any obligation to reimburse City Costs as provided in Article 13.

                  12.5. For Loss of Class 8 Property  Classification.  Developer
reserves the right to cancel,  delay, or abandon construction of all or any part
of the  facility  at any time if any  court  decision  determines  Class 8 to be
unconstitutional  or invalid in any respect,  if a legal challenge to Class 8 is
filed and not resolved to Developer's satisfaction, or if any legislative action
repeals  or  adversely  modifies  the  Class 8  assessment  ratio.  In the event
Developer exercises its rights under this Section 12.5,  Developer shall have no
further  liability to City under this  Agreement,  except its liability for City
Costs under Section 13.1.
                                       13

         13. DEVELOPER PAYMENT OF CITY'S COSTS IN CERTAIN EVENTS.

                  13.1. City Costs.  Developer  acknowledges  that the City will
incur certain costs in discharging  its obligations  under this Agreement.  City
shall provide  Developer with a quarterly  report of costs City expects to incur
in the next calendar  quarter.  City agrees to negotiate  with Developer in good
faith over the timing and  amounts of costs  proposed to be incurred by the City
during the next quarter, in light of then existing business  conditions.  In the
event these  negotiations  result in actual  delays in the City  performing  its
obligations in this Agreement,  City shall be given an additional amount of time
equal to the delay to perform its obligations herein. Developer agrees to refund
the City Costs in the event  Developer  cancels this Agreement for reasons other
than set  forth in  Section  12.2,  12.3 or 12.4.  The  amounts  required  to be
reimbursed  ("City Costs") shall be determined in accordance  with the following
rules:

                         13.1.1.   City  Costs   shall   include   the   actual,
out-of-pocket  costs to the City in planning,  designing,  and  constructing the
infrastructure  for the  Developer's  expansion  described in this Agreement and
shall  include  all  reasonable  out-of-pocket  costs  of  planning  and  design
professionals,  and all reasonable costs of labor and materials actually used in
constructing the infrastructure required under this Agreement.

                         13.1.2. City Costs shall not include: (a) any costs for
work done or services  performed by City employees  which were not  specifically
hired by the City for work  limited  to this  Facility;  or (b) the value of any
time spent by full-time City employees or the cost of their salaries,  wages, or
benefits.

                  13.2.  Accounting.  On a periodic basis, but no less than once
every month,  City shall provide  Developer  with a written  itemization  of all
costs  incurred from the inception of the Facility to date. In addition,  at any
time Developer may request from City a written  itemization of such costs,  City
shall provide such  itemization  within six working days. In the event Developer
disagrees  with any cost  entry or entries on any  itemization,  it may  provide
written  objection to City within ten days of receipt,  at which time City shall
review and respond to the objection  within ten working days. If Developer still
disagrees with the cost entry being charged to it, the party shall first attempt
to resolve the dispute through  negotiations up to the level of City Manager and
the Developer's Project Manager as provided in Section 5.8.

                  13.3. Mitigation.  Notwithstanding any obligation of Developer
to reimburse  City Costs,  any amount owed by Developer  for City Costs shall be
reduced or mitigated to the extent City can use such construction  either at the
time Developer  notifies City of  cancellation,  delay, or abandonment of all or
any part of the Facility or within  seven (7) years after such  notice.  If City
cannot use such  construction  within one year,  then  Developer  shall pay City
annually,  within  sixty (60) days of  Developer's  receipt  of an invoice  with
supporting documentation and calculations, an amount equal to the City's average
cost of borrowed funds until such time as City can use such construction,  up to
a maximum of seven (7) years. In the event that neither party can use any of the
constructed  items,  the  parties  shall use good faith  efforts to arrive at an
equitable resolution of the issue.
                                       14

         14. DEFAULTS AND REMEDIES.

                  14.1. Events Constituting  Developer Default.  Developer shall
be deemed to be in  default  under  this  Agreement  (a  "Developer  Performance
Default") if (a) Developer commits a material breach of any obligation  required
to be performed by Developer herein,  and (b) such breach continues for a period
of one hundred twenty (120) days after written notice thereof by City, Developer
fails to commence the cure of such breach and, thereafter,  to diligently pursue
the same to completion.

                  14.2.   Remedies  to  City.   In  the  event  of  a  Developer
Performance  Default,  which  default is not cured  within any  applicable  cure
period,  City shall  have the right to seek and  obtain all legal and  equitable
remedies otherwise available to it.

                  14.3. Events of Default by City. City shall be deemed to be in
default under this Agreement (a "City Performance  Default") if (a) City commits
a material  breach of any  obligation  required to be  performed by City herein,
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,
and such breach  continues for a period of thirty (30) days after written notice
by Developer.

                  14.4.  Remedies of Developer.  In the event City is in default
herein, Developer shall have all legal and equitable remedies available to it.

         15.  FORCE  MAJEURE.   In  addition  to  specific  provisions  of  this
Agreement,  performance  by  Developer  hereunder  shall  not be  deemed to be a
default  where  delays or  inability  to perform  are due to war,  insurrection,
strikes,  lockouts, riots, floods, earthquake,  fires, casualties,  acts of God,
acts of the public enemy, epidemics, quarantine restriction,  freight embargoes,
lack of  transportation,  governmental  restrictions  or  priority,  litigation,
unusually  severe weather,  inability (when the party which is unable to perform
is substantially without fault) of any contractor,  subcontractor or supplier to
perform acts of the other party,  or acts or the failure to act, of any utility,
public or  governmental  agent or entity,  litigation  relating to the  Facility
initiated  by a party  other than  Developer  beyond the  control or without the
fault of Developer.  In the event that  Developer is unable to perform due to an
event  constituting  force majeure as provided for above, and such excused delay
is the proximate  cause of City being unable to perform in  accordance  with the
terms of this Agreement, then the time for performance of City shall be extended
for a period of time equal to the period of the delay.  An extension of time for
any such cause shall only be for the period of the enforced delay,  which period
shall  commence to run from the time City is notified by Developer in writing of
the  commencement  of the cause.  If such force  majeure  adversely  impacts the
economic  viability of the Facility (in Developer's sole discretion),  Developer
shall have the right,  if  applicable,  to stop or delay  construction.  In such
event, Developer shall reimburse City for City Costs as provided in Article 13.
