          the Product,  as well as all  processes,  machines,  manufacturers  or
          composition  of  matter  which  ADOT of any  affiliate  may  conceive,
          develop, acquire or otherwise obtain rights to during the term of this
          Agreement  which  relate  to the  Product  or any of its  parts or the
          commercial applications presently utilizing such Product. ADOT further
          agrees that:

                    1.   The flat panel  displays  will include a spatial  light
                         modulating   semiconductor   device,   which   will  be
                         line-addressed  and of compact size. More particularly,
                         the display should include a  line-addressable  spatial
                         light  modulator,   wherein  a  detectable   metallized
                         membrane  defining a deformable mirror is mounted above
                         a semiconductor  substrate in spaced  relationship with
                         respect thereto.

                    2.   The membrane in the modulator  will have a matrix array
                         of  floating  conductive  field  plates  disposed on an
                         insulating  layer  covering the  substrate to define an
                         array of air gap capacitor cells  addressable by an x-y
                         matrix array of field effect address transistors formed
                         in the substrate with the degree of membrane deflection
                         of each air gap capacitor cell being dependent upon the
                         corresponding field effect address transistor.

                    3.   The  application  for such a solid state  spatial light
                         modulator is in  combination  with a large  matrix-area
                         charge coupled device light imager for use in obtaining
                         real-time,   two-dimentional  optical  transforms.  The
                         solid state  spatial  light  modulator  will  include a
                         membrane  modulator  on the  backside of a large matrix
                         area charge coupled device (CCD) light imager.  In this
                         type of light modulator, an electronic charge

                                       6
<PAGE>

                         should be input into the front side of the CCD  imager,
                         with the entire frame being subsequently transferred to
                         the backside membrane  modulator  structure through the
                         semiconductor  substrate of thinned  silicon  material.
                         Thinning and subsequent  additional backside processing
                         should provide the support for the membrane  modulator,
                         while  flatness and the  front-side  CCD  operation are
                         maintained. The membrane will be applied to the silicon
                         substrate and the subsequent electrical bonding to both
                         the CCD and the  membrane.  This  type of  solid  state
                         light   modulator   involves   device   processing  and
                         patterning   on  both   sides   of  the   semiconductor
                         substrate.

                    4.   Membrane-type   light   modulators   should  produce  a
                         photo-induced charge in the depletion region of the air
                         gap  capacitor  associated  with  the  portion  of  the
                         metallized  membrane  through which  residual  light is
                         transmitted. There will be an increase in the thickness
                         of the  metal  layer  of the  membrane  to  render  the
                         membrane more opaque to incident  light.  The thickened
                         metal  layer  of the  membrane  structure  reduces  the
                         deflection response of the membrane, thereby increasing
                         the required  operation  voltages to a desirable degree
                         for affecting a desired membrane  deflection  response.
                         The Spatial Light  Modulators  will employ a deformable
                         membrane  structure  as a  component  thereof  when the
                         collapse  voltage of the membrane is exceeded.  In this
                         instance,  the membrane  collapses into engagement with
                         the gate oxide surface of the  semiconductor  substrate
                         when the  voltage  applied  to the  membrane  exceeds a
                         predetermined   magnitude,  and  the  membrane  remains
                         bonded to the gate oxide  surface even after removal of
                         the voltage applied to the membrane.

                    5.   The spatial light modulator which is of a compact small

                         input,   wherein  a  metallized   membrane  defining  a
                         deformable mirror disposed in spaced  relationship with
                         respect   to   a   semiconductor   substrate   of   one
                         conductivity  type  cooperates with an x-y matrix array
                         of floating  conductive  metallic  field plate  members
                         disposed on an insulating layer covering the substrate.
                         Together,  the  metallized  membrane  and the  metallic
                         field  plate  members   define  an  array  of  air  gap

                         capacitor  cells  addressable  by field effect  address
                         transistors formed in the semiconductor  substrate in a
                         line-by-line addressing scheme.

                    6.   The  metallized  membrane  comprises  at least one thin
                         metal layer  presenting a light  reflective  surface to
                         incident  light  mounted  on  a  flexible  non-metallic
                         carrier  layer of organic  polymeric  material  such as
                         nitrocellulose.  The  array  of  field  effect  address
                         transistors  should  be  formed  in  the  semiconductor
                         substrate in a number of different  configurations  but
                         generally  includes  respective  drain  regions  of the
                         other  conductivity  type  or  opposite  to that of the
                         semiconductor  substrate and common to all of the field
                         effect address transistors  arranged in a single column
                         of  the  x-y  matrix  array  of  address   transistors.
                         Additionally,  a second doped region should be disposed
                         in   the   semiconductor    substrate   and   extending
                         substantially  beneath a respective  column of floating
                         metallic field plates. An upstanding grid of conductive
                         polycrystalline   semiconductor   material,   such   as
                         polysilicon, is disposed on the insulating layer of the
                         semiconductor  substrate  extending  upwardly therefrom
                         and  overlaying  the  respective  drain  regions of the
                         other  conductivity   type.  The  metallized   membrane
                         structure is mounted upon suitable  contacts applied to
                         the upstanding grid of polysilicon material so as to be
                         disposed  in space  relationship  with  respect  to the
                         individual  floating  metallic field plates in defining
                         one plate of each cell included in the array of air gap
                         capacitor  cells.  Light  incident  upon  the  membrane
                         structure is essentially  reflected by a surface of the
                         metal layer thereof.  The individual  floating metallic
                         field plates form the other plate of the respective air
                         gap  capacitor  cells and are opaque to light such that
                         any light leakage  transmitted  through the  metallized
                         membrane  is  prevented  from  depleting  charge in the
                         active  regions  of the array of filed  effect  address
                         transistors.

                    7.   The  membrane  structure is subjected to a bias voltage
                         of a  predetermined  magnitude,  while  the  individual
                         floating  metallic  field plates  derive a signal input
                         for each  column or row thereof  from a  charge-coupled
                         device  delay line  which  addresses  the field  effect
                         address  transistors  on line at a time.  A decoder  is

                                       8

                         connected to the plurality of air gap  capacitor  cells
                         included in a row of columns of the matrix  array,  the
                         decoder  being  operable  to select one line of the air
                         gap capacitor cell at a single time for readout.

                         Variations in the configuration of the x-y matrix array
                         of  field  effect  address  transistors   included  and
                         embodiment wherein the second doped region of the other
                         conductivity  type  extends  fully  between  the common
                         drain  regions of the other  conductivity  type and the
                         channel stop region of the same one  conductivity  type
                         and  the   channel   stop   region   of  the  same  one
                         conductivity  type  as  the  substrate,  thereby  being
                         disp9osed  beneath the floating  metallic  field plates
                         and   partially   beneath   the   upstanding   grid  of
                         polysilicon material.  Another embodiment also included
                         will be a self-aligned  high energy implant of a dopant
                         material  of the  other  conductivity  type in the area
                         between adjacent sections of the upstanding polysilicon
                         grid  structures  so as to produce an  implanted  doped
                         region of the other  conductivity  type  having a first
                         portion  of  increased  depth  below  the  subsequently
                         deposited  matrix  array  of  floating  metallic  field
                         plates and a shallow  peripheral portion extending into
                         engagement  with the  channel  stop  region  and to the
                         boundary of the upstanding  polysilicon  grid structure
                         in spaced  relationship  to the drain  region.  Another
                         embodiment  employs a buried drain regions of the other
                         conductivity type which are implanted to a depth within
                         the  semiconductor  substrate below the surface thereof
                         on which the insulating  layer is disposed.  The second
                         doped region of the other  conductivity type underlying
                         the matrix  array of  floating  metallic  filed  plates
                         should   extend   partially   beneath  the   upstanding
                         polysilicon  grid  structure  in  the  area  proximally
                         related to the buried drain region,  but is spaced from
                         the channel stop region  disposed on the opposite  side
                         thereof.

                         The  light   valve   technology   will  have  the  same
                         technology  as the active matrix  twisted  pneumatic LC
                         technologies    for   direct    view   and    camcorder
                         applications.  Because  the  electro-optical  effect is
                         polarization  rotation,   this  technology  requires  a
                         polarizer  and an  analyzer.  The  addressing  mode  is
                         electrical and requires a switching device  (non-Linear

                                       9

                         element) for each individual pixel in order to obtain a
                         high  contrast  for a high  information  content  light
                         valve.  This  switching  device will be a  two-terminal
                         device  (MIM,PIN-diode,  or TFD-R) or a  three-terminal
                         device   (this  film   transistor,   TFT).   Thin  film
                         transistors made in hydrogenated  amorphous  silicon on
                         glass  or in high  temperature  polysilicon  on  quartz
                         should be used.  Thin Film Diode + Reset )TFD-R) active
                         matrix  LC  light  valves  have a thin  film  diode  as
                         switching  device and a four - voltage  level row drive
                         scheme  (also called  reset drive  scheme).  The active
                         plate  requires  only  three  mask  steps  and  the TFD
                         occupies only 1 percent of the pixel area, resulting in
                         a large  aperture  ratio.  The light valves will have a
                         two-terminal  switches with a non-uniform  transmission
                         of the  light  valve due to the  spread of the  forward
                         voltage of the switch.  The special driving schemes for
                         the TFD-R and the D2R two-terminal  switch technologies
                         eliminate this non-uniformity.  The light valve for 256
                         gray  scales and a  contrast  ratio in excess of 200:1,
                         The  electron  field-effect  mobility  of  a-Si  is low
                         (0.2-1cm2/V  s).  Because  the  hold  mobility  is even
                         lower,  alla-Si8  thin film  transistors  are n-channel
                         type   common   structure   for  the  a-Si   thin  film
                         transistors in the  inverse-staggered  structure.  This
                         technology requires eight mask steps and crossovers.  A
                         forward  staggered  (or  top  gate)  structure  is also
                         possible in a-Si TFT technology.  High temperature (HT)
                         (600-1000(Degree)Company)p-Si   thin  film  transistors
                         will be fabricated on PLZT substrates. High temperature
                         p-Si TFT's  have a  self-aligned  structure  and a high
                         field-effect  mobility.  Integrated  HT  p-Si  row  and
                         column drivers are possible  because of this high field
                         effect mobility.  The contrast ratio of the light valve
                         will be  based on a  projection  lens  that can  accept
                         light  rays  within a  certain  solid  angle  from each
                         pixel.

                    8.   The overall  transmission  will have a T light valve of
                         10.5  percent for an active  matrix light valve with an
                         aperture ration of 35 percent.

Seller and Wang Family  Trust  LTD.,  a Hong Kong  corporation  having its North
American  office Wang Tr, c/o Leggat  Baldwin  Keesmaat,  20 Hughson St.  South,
Hamilton,  Ontario, Canada, L8N 3P6, as buyer and Wang Family Trust LTD as buyer
replaces and is in the stead of all previous  Agreements,  contracts  and orders
between ADOT and Wang Family Trust LTD.

     WHEREAS,  ADOT is in the process of  manufacturing  products for electronic
outdoor flat panel displays ("the Products" and/or "the Units"), and is the sole
owner of certain proprietary rights relating to such Products including, but not
limited to all rights relating to United States Patents pending  therefore it is
agreed:

     A.   That ADOT will utilize proprietary semiconductor processing technology
          to maximize  pixel density and reduce  activation  voltage  increasing
          light  transmission  (brightness)  through a reduction  in the surface
          area of the  material  required for the  non-transmissive  electrodes.
          Advanced Optics Electronics, Inc. will provide a manufacturing process
          for a high density electro-optic array.

          Advanced  Optics  Electronics,  Inc.  shall  provide  a  high  density
          electro-optic  light  valve  array  with  reduced  operating  voltages
          compatible with or to exceed current  commercially  available  silicon
          large scale integration  technology and display circuitry designed for
          use with light emitting diodes.

     B.   That such  reduction is an important  inducement and benefit to Buyers
          and  to  significantly  reduce  Buyer's  cost  of  operations  of  the
          Products.

     C.   That Wang desires that ADOT build,  test,  and install two large scale
          electronic flat panel moving color image display  boards,  hereinafter
          referred  to as Units A and B capable  of being  viewed by  interstate
          motorists  at a distance of no less than one hundred and fifty feet by
          employing  the  above  referenced  developments  by ADOT  to  minimize
          operating  voltages  that will be  required  by Buyer to employ in its
          operation of the Products.

     D.   Due to the  confidential  nature of  technical  processes  and systems
          described in this  Agreement  and matters of  confidential  concern to
          Buyer in its industry;  Buyer and Seller jointly agree not to disclose
          the terms and  conditions  herein  unless to a U.S.  domestic bank for
          financing  of all or a  portion  of the  purchase  herein.  When  this
          Agreement is completed disclosure may be made.

     E.   In the event that any part of the  Agreement  is breached or violated,
          Buyer then

                                       1

     17.  Governing Law. This  Agreement  shall be governed by, and construed in
          accordance with, the laws of each State where final installation is to
          be completed.

     18.  Waivers; Amendments. No waiver of any rights hereunder by either party
          shall  operate as a waiver of any other  rights,  or of the same right
          with respect to any  subsequent  occasion for its exercise,  or of any
          right to  damages.  No waiver by  either  party of any  breach of this
          Agreement  shall be held to constitute a waiver of any other breach or
          a  continuation  of the same  breach.  All  remedies  provided by this
          Agreement are in addition to all other remedies  provided by law. This
          Agreement may not be amended except by a writing signed by each of the
          parties hereto.

     19.  Successors and Assigns. This Agreement shall be binding upon and shall
          inure to the benefit of the  permitted  successors  and assigns of the
          parties hereto.

     20.  Severability.  If any condition of the Agreement  should be determined
          to be unenforceable or illegal,  it shall be deemed severable from the
          other provisions hereof, which shall remain valid and enforceable.  In
          the event that the relative benefits,  habilities,  and obligations of
          either party to the  Agreement as compared to those of the other party
          hereto  are  significantly  increased  or reduced by the action of any
          judicial or  administrative  authority the parties agree to enter into
          immediate good faith  negotiations to amend this Agreement in a manner
          which will  fulfill the  original  intention of the parties in a legal
          manner.  This  Agreement  shall remain in full force and effect during
          the course of such negotiations and thereafter until validly amended.

     21.  Counterparts.  This  Agreement  may may be  executed  in three or more
          counterparts,  each of which shall be deemed an  original,  but all of
          which together shall constitute one and the same instrument.

     22.  Prior Understandings. This Agreement represents the complete Agreement
          of the parties with respect to the  transactions  contemplated  hereby
          and supersedes all prior Agreements and understandings.

     23.  Headings.  Headings in this  Agreement are included for reference only
          and

          shall have no effect upon the  construction or  interpretation  of any
          part of the Agreement.

     24.  Arbitration.  Any  disagreements  arising out of the provisions of the
          Agreement  will be decided by  arbitration in New York City, New York,
          in accordance with the Rules of the American Arbitration  Association.
          Each party will appoint an arbitrator,  and the two thus selected will
          designate  a third.  If either of the  parties  fails to  appoint  its
          arbitrator  within  sixty  (60) days  after  receipt  of notice of the
          appointment,  by the other, of its  arbitrator,  or if the arbitrators
          fail to appoint a third,  then the  American  Arbitration  Association
          will have the  power,  on the  request  of either  party,  to make the
          appointments  which  have not been  made as  contemplated  above.  The
          arbitration  will be held as  promptly  as  possible  at such time and
          place as the arbitrators  may determine.  The decision of the majority
          of the arbitrators  will be final and binding upon the parties hereto,
          and the  expense  of the  arbitration  will be shared  equally  by the
          parties.  Judgment  upon the award may be entered in any court  having
          jurisdiction,  or application may be made to such court for a judicial
          acceptance  of the award and an order of  endorsement  as the case may
          be.

     IN WITNESS WHEREOF the parties have caused this Agreement to be executed by
their  respective  officers  thereunto  duly  authorized  and have caused  their
respective corporate seals to be affixed hereto as the date first above written.
