ITEM 1.  BUSINESS


General

         Power Spectra, Inc. ("Power Spectra," "PSI" or the "Company") is a high
technology  California based corporation whose core competence is the design and
efficient  fabrication of proprietary  power  semiconductor  systems that switch
megawatt power levels at  sub-nanosecond  pulse  durations with excellent  pulse
integrity and repeatability. Power Spectra was organized in 1979 and operates as
a single  business  segment.  Prior to the second half of 1996,  the Company was
largely  involved in R&D.  Until 1996,  the  Company had  primarily  focused its
technology on military applications.

         In  mid-1996,  the  Company  made a  decision  to focus the bulk of its
efforts on the  development  of Ground  Penetrating  Radar (GPR)  technology and
systems for a variety of commercial  applications.  Power Spectra had launched a
comprehensive   analysis  of  the   commercial  GPR  systems   marketplace   and
simultaneously had successfully tested an application of its enabling technology
in a stand-off GPR system. Based on this demonstration and the subsequent market
assessment,  the Company changed its principal  business focus from the military
to the commercial sector.

         PSI believes that it has identified  important new market opportunities
for its new GPR products with the potential for  significant  growth and profit.
These   opportunities  could  have  application  in  the  mining  and  petroleum
exploration and exploitation industires, the utilities industry, the oil and gas
transmission  industry,  the  communications  industry,  and in the construction
industry.  GPR initiatives  which the Company has initiated or currently intends
to initiate  include:  1) a joint venture for the  development of commercial GPR
based mineral and petroleum  exploration  systems, of which its first product is
nearing  completion;  2) the development of a vehicle-mounted GPR system for the
location  and  identification  of  underground  utilities  and  pipelines,   the
development  of which is expected to be completed  during  1998;  and, 3) in the
future, a joint venture for the development of a  helicopter-mounted  GPR system
for the location and  identification  of buried pipelines and artifacts.-  Other
potential  applications  may include  such  products as Borehole  Radars for oil
exploration,  distance  measurement sensor systems, as well as products designed
to  improve  the  performance  of  military  radars,  communications,  and  both
offensive and defensive information warfare systems.*

Actual future  performance  may differ  materially  from the  Company's  current
expectations.  The  reader is  advised to review  "Management's  Discussion  and
Analysis of Financial  Condition and Results of  Operations - Factors  Affecting
Operating  Results"  for a  discussion  of  factors  that  could  affect  future
performance.


                                       3
<PAGE>

         Power Spectra  develops,  designs,  manufactures and markets GPR sysems
and  laser-based  measurement  products that utilize the  Company's  proprietary
Gallium Arsenide ("GaAs") semiconductor  switching devices, which are capable of
generating extremely rapid, high-power  electromagnetic  impulses. The Company's
products  are  currently   based  on  two  GaAs  switches,   the  Bulk  Avlanche
Semiconductor  Switch  (BASS(TM))  and the  PSIristor(TM).  Since its inception,
nearly $70 million has been  invested in developing  the  Company's  proprietary
BASS(TM) and its companion thyristor  (PSIristor(TM))  product  technology.  The
Company  believes  that one of the most  important  features of Power  Spectra's
switches  is that they are the  enabling  technology  for  high-power  microwave
transmitters  capable of  generating  signal  strengths  up to 1,000  times more
powerful than existing switching  technologies.  These  semiconductor  switching
devices  represent  the core  enabling  technology  for the  development  of the
Company's  mobile GPR systems which have  demonstrated in test conditions  their
capability to produce three-dimensional images of underground objects, including
non-metallic objects such as plastic pipe and plastic landmines.

         The BASS(TM) is an optically triggered,  high power GaAs switch that is
roughly the size of a conventional  power  transistor.  In its "off" state,  the
device  exhibits  a  very  high   resistance  due  to  the  unique   performance
characteristics  of  GaAs.  The  BASS(TM)  changes  from a  non-conducting  to a
conducting  state in  approximately  100 trillionths of a second  (picoseconds),
with pulse durations of less than two billionths of a second (nanoseconds),  and
can  switch   voltages  in  excess  of  17  thousand  volts   (kilovolts).   The
PSIristor(TM)   is  also  a  GaAs   switch   and  has   many  of  the   BASS(TM)
characteristics.  The primary differences are input power, cost and device size.
The  PSIristor(TM)  is smaller,  less costly to manufacture,  easier to use, and
operates at lower output power levels compared to the BASS(TM).  From a customer
perspective,  the  PSIristor(TM)  bridges  the  gap  between  the  BASS(TM)  and
conventional power semiconductors.

         The use of GaAs for high speed applications has increased  considerably
in recent years,  especially with the proliferation of its use in cellular phone
circuitry.  It should be noted, however, that the Company's technology is unique
in that the GaAs  material  the  Company  uses is  typically  five-to-ten  times
thicker  than that of  conventional  devices.  As a result,  although  the Power
Spectra  BASS(TM)  devices are about the same  physical  size as a  conventional
power  transistor  chip,  the volume of GaAs  material  utilitzed  in the actual
switching  process is hundreds of times greater than that of a power transistor,
allowing  the  PSI  devices  to  handle   substantially   higher   voltages  and
consequently  higher power than  conventional  devices.  The  Company's  devices
operate at up to 400 times the voltage  levels of the more  conventional  planar
devices.  Bulk devices,  such as those  produced by PSI, are only  fabricated in
several  government  laboratories and universities,  and thus far, have not been
commercially available.


Commercial Products

         In 1996,  when Power  Spectra  changed  the main focus of its  business
efforts  from  the  military  market  to  the  commercial  sector,  the  Company
identified and began  internal  initiatives to develop the products and services
for three separate commercial applications,  each with what the Company believes
is a significant market potential.* These initiatives  included:  1) the LandRay
joint venture for the  development of commercial GPR based mineral and petroleum
exploration  systems;  2) the  PEAC  joint  venture  for  the  development  of a
helicopter-mounted  GPR system for the  location  and  identification  of buried
pipelines and artifacts; and 3) completing the development of an electro-optical
rangefinder the E-OR 230(TM) for the industrial  marketplace.  Subsequently,  to
minimize   short-term  expenses  and  to  field  an  operating  system  earlier,
development of the  helicopter-mounted  GPR system was deferred, and the Company
has  directed  its  efforts to a  vehicle-mounted  GPR system for  location  and
identification of buried pipelines,  utilities,  fiber optic cable bundles,  and
artifacts.  From a technical standpoint,  the vehicle mounted system development
is a natural precursor to a helicopter mounted system.

         Notwithstanding  the fact that the  applicability of both the Company's
BASS(TM) and PSIristor(TM) device technology to ground penetrating radar systems
has been technically demonstrated, at this early stage of its shift in strategic
business  focus,  the Company has not yet  generated  significant  revenues from
sales of its commercial  products.  The first GPR product developed for LandRay,
the SEEKER(TM),  is just currently  entering initial  production.  The following
sections  discuss  potential  future products and  applications of the Company's
core technologies which the Company is considering pursuing,  but which have not
yet been  developed,  tested or deployed.  There can be no assurance that any of
the  commercial  products  discussed  below will be  successfully  developed  or
accepted in their target markets,  that revenues generated by such products will
be sufficient to return the cost of their development,  that the Company will be
successful in  developing  additional  new  products,  that the Company will not
experience  delays in  developing  such  products,  or that such  products  will
achieve commercial success. A sustained failure to successfully develop and sell
new products would have a material adverse effect on the Company's  business and
its results of operations.

         Power Spectra currently has three business lines, all based on its core
technology: 1) Ground Penetrating Radar; 2) Industrial Sensors; and, 3) Military
and Government.  Ground Penetrating Radar is expected to command the bulk of the
Company's  attention for the  foreseeable  future and is expected to exploit the
technical   advantages  of  the  BASS(TM)  and   PSIristor(TM).*   Although  the
Military/Government  line of business has historically generated the majority of
the Company's revenues, current management plans call for pursuing this business
on an opportunistic basis.

         Ground Penetrating Radar (GPR) Business

         Power Spectra is pursuing several potential business opportunities that
apply its  technology to GPR systems  designed to detect and render  precise 3-D
images of buried materials. The Company's current efforts are largely focused in
two areas: a hand-held GPR system for use in gold mines, being developed through
the LandRay joint venture,  and a vehicle-mounted  GPR system for use in general
utility mapping, being developed internally.

         In 1996, the Army Research Laboratory ("ARL") successfully demonstrated
an  experimental  GPR system,  enabled by Power Spectra  technology,  that could
detect buried anti-personnel  landmines from a stand-off range of 500 feet. This
event is significant in that all other GPR systems of which the Company is aware
can only operate in a ground contact or near ground contact mode. This technical
achievement   encouraged  Power  Spectra  to  further  develop  its  GPR  system
technology  for  commercial  applications.  As a result of its GPR testing,  the
Company  believes  that it is well  positioned  to  make  significant  near-term
contributions in the areas of mineral resource detection and underground utility
detection.*

         One of the  advantages  of the Power  Spectra's  GPR  technology is the
ability to operate from a stand-off position,  generally defined as an operating
position  more  than 18  inches  above the area to be  scanned.  With  other GPR
systems the antennas are literally  dragged  across the ground or are very close
to the ground,  and as such,  may be limited in the areas they can survey due to
obstacles such as vegetation and rocks.

         The success of the ARL demonstration gave considerable impetus to Power
Spectra   management  to  conduct  the  analysis  leading  to  the  decision  to
concentrate  the Company's  efforts on GPR. As a result of this analysis,  Power
Spectra believes that its GPR technology could potentially  provide  significant
advantages in the following business areas:*

          -    Mineral resource  detection 
          -    Underground pipe and conduit mapping
          -    Borehole  radar  for  oil/gas  exploration
          -    Unexploded  ordnance detection   
          -    Anti-personnel   mine  detection  and  classification
          -    Archeology and antiquity mapping

         Remote sensing  technologies  such as seismic  reflection,  impulse and
stepped frequency GPR,  resistivity and induction logging and other technologies
have been used for mineral  exploration  for many years with mixed results.  The
limitations of poorly  resolved  imagery,  coupled with expensive and cumbersome
techniques  generally require expert  interpretation,  making seismic reflection
applicable to the  characterization  of large geologic  features with high value
potential, such as oil and gas. GPR has not found wide use in mining and oil and
gas exploration due to its  historically  limited range,  poor  resolution,  and
difficulty in interpreting the data.

         The Company has conducted  analysis and calculations  which have led it
to believe that the benefits of the Power Spectra GPR to mineral exploration and
development  include  significantly  increased  range,  improved  resolution and
greater ease of data interpretation.*

         LandRay Technology, Inc.

         LandRay Technology, Inc. (LandRay), a Delaware corporation, was founded
in 1996  as a joint  venture  between  Power  Spectra  and a  group  of  private
investors to develop and  commercialize  the  Company's  proprietary  GPR system
designs for sensing,  detection, and location of subterranean metal deposits and
geophysical  profiles to aid in the  exploration for minerals and fossil fuels -
in essence, for mineral and petroleum exploration and exploitation.  The Company
believes that these sensors could be deployed from  ground-based,  in-mine,  and
in-borehole platforms.*

         In  exchange  for  GPR  development  contracts,   LandRay  received  an
exclusive, royalty-free license to use the Company's GPR technology in the areas
of mineral and petroleum  exploration and  exploitation.  Although Power Spectra
received an initial 50%  shareholding  in LandRay for this  license,  subsequent
LandRay  fund  raising  activities  have  diluted  the  Company's  position,  as
contemplated  by the  originating  agreements.  LandRay  contracted  with  Power
Spectra for a mining GPR concept  demonstration  ($550K)  and  subsequently  the
Company  negotiated  a  $3.0M  LandRay  contract  for the  development  of a GPR
production system, of which only the first part has been defined, the SEEKER(TM)
contract ($1.2M), which included a full system verification in an operating gold
mine and the delivery of two production units. The SEEKER(TM) is the first fully
developed  Power Spectra GPR product,  and two units are now in production  with
initial  deliveries  to LandRay  scheduled  for the second  quarter of 1998.* To
date,  the Company has  received a total of $1.05M from the LandRay  development
contracts.

         As of  December  31,  1997,  Power  Spectra  held  about a 31% stake in
LandRay,  making  Power  Spectra  the  largest  single  shareholder.  If LandRay
continues  to raise  additional  funds  through  the  issuance  of  equity,  the
Company's  ownership  percentage in LandRay will continue to decrease.  However,
the joint venture  agreement  stipulates  that the  Company's  share will not be
diluted below 22.7% before LandRay raises equity capital  totaling  $3.55M.  The
Company has no capital  funding  commitments to the LandRay  venture,  but could
elect to participate in future LandRay financings,  if the Board deemed it to be
in the Company's best interests.

         Witnessed and documented tests of the SEEKER(TM) system at the Original
Sixteen  to One Mine in  Alleghany,  CA,  which  has been in  almost  continuous
operation  for the  past 100  years,  have  indicated  that  the  Power  Spectra
SEEKER(TM)  product  technology  can see up to 20 feet into the quartz  rock and
detect  high  grade  gold ore.  In the final  test,  which was  performed  under
stringent  rules,  the device  detected  more than 200  ounces of gold,  thereby
exceeding the contractual requirements for gold deposit detection.

         While LandRay is interested in exploiting the market for other selected
high value minerals, in the near-term it will focus on finding gold in hard-rock
mines.  The world-wide gold production in 1996 was slightly under 2000 tons with
about  330 tons  being  mined in the  United  States.  About  40% of the gold is
derived  from  hard-rock  mining,  with the balance  from  surface  mining.  The
SEEKER(TM)  utility  is  currently  limited  to  hard  rock  mining  operations.
Hard-rock  gold mining  operations  in the United  States  alone yield a revenue
stream  exceeding  $1 Billion per year.  LandRay has  informed  the Company that
plans anticipate garnering a percentage of all gold found with the SEEKER(TM) in
hard rock gold mines.

         Power Spectra  believes that the benefits of this GPR system to mineral
exploration  and  development  companies  include  both  significantly  improved
specificity of deposit  location and improved  characterization  of subterranean
mineral deposits.  The Company believes its proprietary technology is unique and
that it should  prove to have high value to  exploration  companies  who realize
these  benefits.*  Consequently,  LandRay  has  informed  tha  Company  that its
strategy  calls for  retaining  ownership  and  control  of all  SEEKER(TM)  GPR
equipment and to provide exploration support services for a share in the profits
gained.*  PSI will  benefit  from both the  manufacture  and sale of  SEEKER(TM)
systems and from its ownership in LandRay.  In addition,  Power Spectra  retains
all intellectual  property rights for all technology developed under the LandRay
contracts.

         In addition, Power Spectra has conducted considerable analysis with the
objective of eventually developing a BoreHole Radar (BHR) for use in oil and gas
exploration  wells.  Technical  and risk  analysis  is  complete  and LandRay is
contractually  obligated  to grant the  Company a BHR  development  contract  in
mid-to-late 1998 for concept definition and initial prototype  exploration.* The
Company believes that, if successfully  developed,  a borehole radar using Power
Spectra  technology could  significantly  enhance the performance of borehole or
well  logging  analytical  tools.*  Such a radar  could be  designed to directly
measure  dielectric  constant giving a true indication of the presence of oil or
gas.* Other borehole  tools,  with the exception of nuclear  magnetic  resonance
(NMR),  measure  only  secondary  parameters.  NMR,  however,  is limited in its
capability by virtue of its very limited range.  Detailed calculations show that
a Power Spectra borehole radar, if successfully  developed,  could make accurate
measurements at ranges 8-10 times those of NMR.*

         Historically,  GPR has  not  enjoyed  widespread  success  in  borehole
logging, primarily because of the need for high power for it to be effective and
the need to operate at temperatures  generally in the range of 100-150(degree)C.
The Company  believes that Power  Spectra's GPR could overcome  these  obstacles
because the BASS(TM) is a highly efficient device which can operate for extended
periods on power from compact batteries.* Additionally, in documented tests, PSI
has demonstrated that the BASS(TM) suffered no detrimental effects when operated
at temperatures up to 130(degree)C  without external  cooling.  Future tests are
planned for operation at higher temperatures.*

         Typically  a number of  different  sensors  are  employed  in logging a
single well and, when all the data is reduced, the decision to encase a borehole
(which on average costs about  $1,000,000)  is  frequently  made on a subjective
basis. The Company believes that there is a need for better technology which can
provide more quantitative  data. Since GPR provides for direct  measurement of a
material (i.e.,  dielectric constant,  which is a physical property of materials
that is  directly  measured  by PSI's  GPR  systems)  as  opposed  to  secondary
parameters detected by other sensors, an effective GPR capable of operating in a
borehole environment would make a major contribution.  There are several patents
for borehole radar concepts,  but it appears that the results fall short because
of limited  range and  difficulty  with  operation  under  severe  environmental
conditions.  The Company  believes that a system  employing  Power Spectra's GPR
technology   concepts,   if  successfully   developed,   should  overcome  these
shortfalls.*

         Vehicle Mounted System

         Power  Spectra  is in the  final  stages  of  development  of a vehicle
mounted GPR system designed to generate true 3-D images of underground pipes and
other  buried  objects  in  near-real  time.  Historically,  GPR  has  played  a
significant  role in the  utility  industry as a tool to locate  pipes,  thereby
reducing the risk of damage  during  construction  and  repairs.  Unfortunately,
existing systems generally require their antennas to have ground contact or near
ground contact. These systems generally have the following limitations:

    - Large  areas  or  stretches   cannot  be  economically   surveyed
    - Detection  of  plastic  pipes and  fiber  optic  conduits  is not reliable
    - True 3-D mapping is generally not achievable 
    - The data is extremely difficult to interpret
    - Penetration depth is limited

         The Power  Spectra  GPR system is  designed to address all of the above
issues.* Additionally,  the Company has already solved many of the technical R&D
problems  associated  with  achieving  true 3-D maps from a stand-off  position,
including the detection of plastic  pipes and conduits.  The Company's  BASS(TM)
has extremely high pulse-to-pulse  fidelity and operates at more than 1000 times
the power of any known existing system.  The Company believes that this, coupled
with advanced proprietary signal processing  technology will result in increased
penetration depths when compared with existing systems.*

         With respect to the development of a vehicle mounted GPR system,  Power
Spectra's objectives are to demonstrate a system that would:

          -   Render precise 3-D images of underground objects,
          -   Detect and map underground infrastructures,
          -   Locate leaks in underground pipelines, and 
          -   Eliminate unnecessary excavation expense.

         The Company  believes its  proprietary  GPR systems,  if development is
successfully  completed,  will be both technologically and economically superior
to conventional detection and mapping methods, because as envisioned,  they will
function  from a  "stand-off"  position  (more than 18" off the ground) and will
produce real-time images.* Power Spectra intends to complete the development and
initial  testing  of its  vehicle-mounted  GPR  system  during the first half of
1998.*

         In recent  years,  the utility  industry  has  employed  horizontal  or
directional  boring  in  the  laying  of  new  pipes.  Because  of  the  serious
consequences of damage to other  utilities,  utility  companies  usually require
"potholing"  every  five-to-ten  feet.  This entails digging a hole and exposing
existing  utility lines by hand or by  evacuating  the soil using large water or
air driven vacuum equipment mounted on trucks. This is a very expensive and time
consuming operation. Power Spectra believes that its vehicle mounted GPR system,
if successfully  developed,  could provide detailed 3-D maps with one pass along
the line of new construction, thereby reducing the need for "potholing".*

         One construction  company with whom the Company has spoken is currently
completing  the laying of 13,000 miles of fiber optic  conduits  along  railroad
rights of way.  They  report that it costs  $3,000 per mile to examine  existing
drawings of other  utilities  along those rights of way and that these  drawings
often do not adequately portray the true locations. As a result they require two
engineers  with each piece of digging  equipment to minimize the  disruption  to
other  lines.   Even  then,  the  damage  rate  to  other   utilities  has  been
unacceptable.  This same  company has plans to install more than 10,000 miles of
fiber optic  conduits  once their current  project is  completed.  Power Spectra
believes that its GPR, whether mounted on a railroad  vehicle or a truck,  could
resolve these problems at a fraction of the cost.*

         Many electric power companies employ high voltage  transmission systems
in which  power  cables are encased in buried  steel pipe that also  contains an
insulating  fluid under  pressure.  When this  pressurized  fluid leaks from the
pipe, which frequently occurs,  considerable expense is entailed in locating and
repairing  these leaks.  If a particular GPR system could measure the dielectric
constant of the fluid,  such a leak should be readily  detectable.  Calculations
have been completed  which indicate that the Power Spectra GPR should be able to
readily detect such leaks.* In many areas, these transmission  networks would be
amenable  to being  surveyed  from an  airborne  GPR  platform,  while a sizable
portion would be better suited to a truck mounted system.*

         The Power Spectra development work on a truck mounted GPR, currently in
the late stage of development, could provide the technical basis for an airborne
system on a helicopter  platform.  The antennas,  array configuration and signal
processing  architecture would be very similar,  although certain  modifications
would be required to satisfy the airborne  environment  and increased  stand-off
range.

         The Army  Research  Laboratory  tests have shown that the Company's GPR
technology  can detect buried  anti-personnel  mines at ranges  compatible  with
helicopter operations. However, one of the problems with such operations is that
of classifying the targets. Without a viable target recognition capability,  the
false  alarm  problems  could  be  substantial.  Power  Spectra  has an  ongoing
collaborative  agreement  with a division  of  Lockheed-Martin  to  develop  the
capability  to uniquely  identify  mines in a  background  that  contains  other
targets. This capability,  if successfully  developed,  should be able to denote
the precise type of mine detected.*

         Airborne GPR

         A joint venture company, PEAC, was formed in 1996 between Power Spectra
and EAC Helicopter for the purpose of operating a helicopter  mounted GPR system
for the detection and localization of buried objects, but this joint venture has
never been activated or funded.

         A potential  future business  opportunity for an airborne system may be
in the mapping of pipelines in  compliance  with Federal  legislation  passed in
1996. There are more than 400,000 miles of oil and gas transmission lines in the
United  States.  About 60% of these lines  transmit  natural gas and the balance
transmit crude, gathering and finished petroleum products.

         Because a ground based system is a natural step toward the evolution of
an  airborne  system,  the  decision  was made to develop and market the Vehicle
Mounted GPR before embarking on the development of a helicopter  mounted system.
In October 1997.  Power  Spectra and EAC  Helicopter  agreed to suspend  further
activity, pending development of PSI's Vehicle Mounted Radar system.

         Industrial Sensors Business

         Power Spectra has developed and is just beginning  commercial  sales of
its Electro-Optic  Rangefinder,  E-OR 230(TM),  the first in a potential product
family of industrial measuring sensors.  The Company's E-OR(TM)  electro-optical
rangefinder,  an infrared (IR) laser-based sensing device that measures distance
and speed,  is designed to provide  industrial  optical  sensor  customers  with
important advantages in range, eye safety, beam spot size, stability,  accuracy,
performance  and  cost-effectiveness.  The  heart of the E-OR  230(TM)  is Power
Spectra's Pulsed Optical Source (POS(TM)),  a  PSIristor-switched  pulsed laser,
which is designed to be eye safe, accurate and reliable.

         Power   Spectra's   plans  to  market   the  E-OR   230(TM)  to  OEM's,
manufacturers and systems integrators as an innovative,  attractive  alternative
to ultrasonic proximity sensors and laser diode based photoelectric sensors.

         Power  Spectra's  primary  target market is the light  measurement  and
optical sensors market, which according to Frost & Sullivan is expected to total
over $3 billion in sales in 1998 (an  average  annual  growth  rate of about 11%
over the past five years). The ultrasonic and laser diode sensor market segments
are expected to grow to over $650  million,  and these are the  specific  target
markets for PSI's Industrial  Sensors Business.  Power Spectra believes that its
laser-based  industrial  measurement  sensors can address  the  requirements  of
approximately  20-25% of the  ultrasonic  proximity  sensor  market  segment and
10-15% of the laser diode sensor market segment.*

         Laser diode based  measurement  sensors  using short pulse or modulated
laser technology range in price between $5,000 and $10,000,  and typically offer
very  high  performance   characteristics:   accuracy  to  0.1  inch  and  range
measurements  at distances in excess of 500 feet. In contrast,  ultrasonic-based
measurement  sensors range in price between $165 and $1,000,  and typically they
offer lower performance characteristics:  accuracy between 1-5 inches and target
range measurements from 6 inches to 30 feet.

         The Company believes that with an estimated market entry price of under
$3,000  per  unit,  Power  Spectra's  electro-optical   rangefinder,   a  pulsed
laser-based measurement sensor, provides many of the features of expensive laser
diode  based  sensors  at a  competitive  price,  while  overcoming  many of the
limitations of the less expensive  ultrasonic  based products.* The E-OR 230(TM)
product has an accuracy of 0.25 inch and measures target  distances in excess of
100 feet. Power Spectra's product offers the accuracy of a laser diode sensor at
a much  lower  cost,  and  while  it is more  expensive  than the  lower  priced
ultrasonic  sensors,  it offers greater range,  smaller beam spot on the target,
greater accuracy, and greater temperature stability than most electronic sensors
and most  importantly its accuracy is not affected by acoustic noise,  humidity,
barometric  pressure or turbulence.  Power Spectra believes the E-OR 230(TM) can
fill the price/performance gap between ultrasonic and existing laser diode based
measurement sensors.*

         The Power Spectra electro-optical rangefinder has been designed for the
following potential industrial  applications:  diameter measurements of material
rolls,  liquid and material level  sensing,  equipment  collision  avoidance and
warning,  container  ship loading,  speed and proximity  sensing,  manufacturing
process  monitoring,   robotics  and  automation,  safety  monitoring,   article
profiling and dimensioning, and environmental monitoring.

         Military & Government Business

         Historically,  Power Spectra has dedicated its  technology  development
toward defense market applications. Since 1988, the Company has supported dozens
of  electronic  warfare  ("EW")  systems  tests with  BASS- and  PSIristor-based
impulse  transmitters.  Due to the  thawing of the "cold war" and the  resultant
decline  in  the   emphasis  on  new   technology   developments   for  military
applications,  the Company has not realized any  significant  business  from its
commitment to this market  sector since the ending of the Air Force  contract in
1996. Power Spectra has ceased direct  government  business  development and has
focused its military  business  activities on teaming with major defense systems
companies.

         In August,  1996, Power Spectra executed a strategic alliance agreement
with AEL  Industries  covering  the  marketing  of PSI  Electronic  Warfare (EW)
technology  over a range of specific  programs,  where AEL will take the lead in
marketing the Company's technology to the government. AEL, a division of Tracor,
is well known for its work in electronic  warfare and antenna systems.  To date,
no contracts have resulted from this agreement.

         Although  the Company  may in the future  consider  teaming  with other
major defense systems  contractors,  it will evaluate all new program options on
an  opportunistic  basis, and enter  into only  those programs  that will  bring
sustainable and profitable business to the Company.

         Boeing Program

         On January 1, 1989,  Power  Spectra and The Boeing  Company  ("Boeing")
entered  into a BASS(TM)  products  development  and  marketing  agreement  (the
"Boeing  Agreement").  The Boeing research period of performance expired in June
1994. Under the terms of the amended agreement,  Boeing continued to provide, on
a loan basis,  $3.7  million of  equipment  and  allowed  the Company  continued
rent-free use of this  equipment,  subject to annual review.  In September 1997,
the terms of the agreement  were amended to transfer all assets  provided  under
this agreement to Power Spectra in exchange for the Company's  assumption of all
liability  related to disposal of the  equipment  upon  completion of its useful
life, including but not limited to environmental issues, if any, and restoration
of the building leased from Boeing, if and when the assets are removed.

                                       10
<PAGE>

         Under the amended agreement,  and in exchange for having provided $23.5
million  in  research  and  development  funding,  Boeing  retains a  perpetual,
non-exclusive  license to use the  technology  developed  during the term of the
agreement,  and to market systems containing BASS(TM) devices. In addition,  PSI
will pay  Boeing a  royalty  of 4% of  BASS(TM)  product  sales up to a  maximum
cumulative  royalty  payment of $10 million.  This  royalty  applies only to the
BASS(TM) device itself and not any system or sub-system of which the BASS(TM) is
a part.

         Air Force Contract

         In 1990,  Power  Spectra  was  awarded  the first  phase of a two-phase
competitive  contract for the development of a solid-state  high-power microwave
source for the United States Air Force (the "Air Force  Contract").  This source
was designed to exploit the  capabilities of the BASS(TM) device and was used by
the Air Force to test the effects of high power microwave pulses.

         A Phase II option to the contract was exercised in 1993 and  subsequent
amendments and modifications  were added. The aggregate contract value, with the
addition  of the Phase II  option  and all  amendments  and  modifications,  was
$10,517,881.  PSI has delivered all items required by the contract and all items
were accepted by the  government.  The contract  expired on June 1, 1996, but is
subject to an audit by the Defense  Contract  Audit  Agency for  overhead  rates
applied to the  contract  for fiscal  years 1994,  1995 and 1996.  As such,  the
Company may be subject to  adjustments  up or down on contract  revenues.  While
such audits are commonplace,  the timetable for the audit is unknown at present,
and no assurances  can be given that such audit will not result in a significant
payment obligation to the government.

         Ioffe Agreement

         In 1992,  Power Spectra entered into a technology  license,  technology
transfer,  and  development  agreement  with the  Ioffe  (pronounced  "yahf-ah")
Physical Institute  ("Ioffe"),  St. Petersberg,  Russia (the "Ioffe Agreement").
Funded by the Soviet military, since the 1970's Ioffe had been trying to develop
a device which  operated very  similarly to the BASS(TM),  but at  substantially
lower power levels.  Following the break-up of the former Soviet Union,  Russian
scientists were brought to the Company's Sunnyvale  facility,  sponsored in part
by the U.S.  Department  of  Commerce,  for varying  periods to  facilitate  the
transfer of this  technology  to the United  States.  The  Company  subsequently
obtained a perpetual  license for the manufacture and use of this device,  which
is valid  worldwide,  except for the territory  encompassed by the former Soviet
Union,  and it  remains  exclusive  as long  as the  Company  maintains  royalty
payments  under the terms of the  agreement.  This  device  is  currently  being
produced at Power Spectra's  Sunnyvale  facility as the Company's  PSIristor(TM)
product.  Over the past few years, PSI has continued to make further refinements
and  improvements  to the  manufacturing  process for this  device.  The Company
believes  this product is  complementary  to the  BASS(TM)  and has  significant
potential applications in military and commercial markets.*


Manufacturing

         Power  Spectra  manufactures  all of  its  products  at its  Sunnyvale,
California manufacturing facility, which it leases from Boeing.

         In  1991,  the  Company  completed  the  construction  of and put  into
operation a semiconductor fabrication facility for BASS(TM) development.  Boeing
provided a significant portion of the funds to complete the construction of this
fabrication  facility.  The Company  believes  the  facility  and  equipment  is
suitable for moderate volume production of BASS(TM) and PSIristor(TM) devices to
meet current production requirements.*

<PAGE>

         During 1994, Power Spectra  installed an epitaxial  furnace to a design
specified by Ioffe,  which was the principal  objective of the Ioffe  Agreement.
The Company believes that additional manufacturing capacity, when required, will
be available through expansion within its existing building.* The Company's sole
manufacturing  facility  is  located  in an area  adjacent  to major  earthquake
faults.  The  destruction  of the  Company's  facility due to fire or earthquake
would have a material adverse effect on the Company's results of operations.

         In late 1997, Company management  successfully negotiated and completed
the  transfer of title for all Boeing  equipment  at the  Sunnyvale  facility to
Power Spectra.

         Materials  and  components  used  in the  manufacture  of  devices  are
generally available from a variety of sources.


Sales, Marketing, and Distribution

         The  Company  has  increased  its  focus on  industrial  or  commercial
products,  which the  Company  believes  hold more  promise  for growth than the
military  sector,  where PSI believes  weapons  systems  cutbacks have seriously
limited the near-term  markets for systems in which the  Company's  BASS(TM) and
PSIristor(TM) technologies could make a major contribution.

         Although the Company's  marketing  activities  have been  significantly
curtailed  due to  capital  constraints  and the  focus on new GPR  developments
during this period of transition from the military to the commercial sector, the
marketing goals of the Company include obtaining  development  contracts for new
GPR systems, while continuing to expand and market the industrial/commercial GPR
product line(s).

         The bulk of the Company's  marketing efforts during 1997 was focused on
interacting  with potential  future customers for the purpose of analyzing their
requirements  and making them aware of the  Company's  intentions  and progress.
These  interactions   included  major  utility  companies,   petroleum  pipeline
companies, construction companies and petroleum exploration service companies.

         Power Spectra  currently has no marketing  staff or salesforce.  Senior
management has been handling  marketing  activities  during the GPR  development
period. The Company will only add marketing staff after GPR contract obligations
have been met and a GPR or industrial sensor product production backlog has been
built.  Following the initial GPR system development  period, PSI is planning to
market its GPR products  through  independent  service  providers.*  The Company
anticipates that these service  providers will typically provide GPR services on
a lease and toll basis,  with the Company  retaining title to the GPR products.*
With respect to the Company's  industrial  sensing products,  PSI plans to fully
utilize  the  well  established  distributor  and  manufacturers  representative
networks for such products.*

         Several other products had  previously  been developed and marketed for
industrial or commercial markets,  including:  the BASS-0X(TM) series of impulse
generators, the PGS-400(TM) series of impulse generators, and the POS(TM) series
of  pulsed  lasers.  These  products,  which  are  based on PSI's  BASS(TM)  and
PSIristor(TM) core technology, are used in the Company's GPR systems, Industrial
Sensor  products,  and  Military  and  Government  products.  Promotion of these
products has included news releases,  advertising in trade publications,  direct
mailings, and exhibition at trade conferences.

Competition

         While Power Spectra is not aware of any "in-kind"  competition  for its
enabling  technology,   numerous  conventional  technologies  compete  with  the
Company's BASS(TM) and PSIristor(TM)  based products in various market segments.
The  Company  believes  that the  competitive  factors in its markets are price,
performance,  technical  innovation and size. While the Company believes that it
does, or will, compete favorably with respect to all of these factors, there can
be no assurance  that the Company will be  successful  in achieving  significant
commercial sales of its products under development.

         Ground Penetrating Radar

         The Company  competes,  or is  expected  to compete,  with a variety of
companies in the area of GPR systems, including Geophysical Survey Systems, Inc.
(GSSI), Coleman Research,  GEO Radar and EMRAD Limited (PIPEHAWK).  All of these
companies  have  significantly  greater  financial and  marketing  resources and
products currently on the market.

         Recently,  several European organizations have commenced aggressive GPR
developments.  The U.K. Defense Evaluation & Research Agency (DERA) has embarked
on a multi-year program to develop a helicopter-borne  system for anti-personnel
mine  location  and  identification  along  the lines of the PSI  approach.  The
details of this program are closely held, and data on the  performance  achieved
against mines are classified.

         Another  European  initiative  is the work  commencing  at the EU Joint
Research  Center (JRC) aimed at  developing a  truck-mounted  mine-finding  GPR.
While little  progress has been reported to date,  the program is significant in
that it has a funded budget in excess of $40M.

         Industrial Sensors

         Power Spectra is addressing a niche market for  industrial  measurement
devices using  short-pulse  diode lasers which have integrated driver circuitry.
The industrial  measurement  market is currently  served  primarily by expensive
high-performance  laser-based  systems  at the  top  end of the  market,  and by
inexpensive, lower performance ultrasonic-based systems on the lower performance
end of the market.

         The Company's  competitors in the pulsed-laser based measurement system
market include Laser Diode Products,  Inc., which offers a product which,  while
not a direct replacement,  is a possible substitute for the Company's industrial
sensors. In addition,  future competition is expected to develop from EG&G, Inc.
There can be no  assurances  that these  companies  or others  will not  attempt
technology development sufficient to become the technology leader in this niche.

         Power Spectra also competes with the major proximity  sensor vendors in
the  industrial  measurement  market,  including  Electro,  Micro Switch,  Massa
Products,  and Siemens, which had a combined share of 67% of the world market in
1993. All of these companies have significantly  greater financial and marketing
resources and products currently on the market.

         Impulse Generators

         A number of companies have light-activated  semiconductor  technologies
which  compete with the BASS(TM)  device in this market.  The major  competitive
technology in this area is the linear-mode  light-activated switch. In addition,
other companies and government  laboratories are studying  semiconductor devices
like the BASS(TM).

         The Company faces intense  competition  for  government  contracts from
larger companies with conventional technology,  which have substantially greater
financial  and marketing  resources  than the Company.  The largest  competitors
include Hughes, Raytheon, Lockheed Martin, TRW, Tracor, and Northrop Grumman.

Patents and Proprietary Rights

         Power Spectra relies  primarily on its  technological  and  engineering
capabilities  for the  development  of its business.  The Company  believes that
patents for concepts and  processes  developed by its  employees  are a critical
element  for the  protection  of its future  growth.  The Company  files  patent
applications  for certain  concepts and processes as appropriate.  Power Spectra
currently  holds 5  patents  with 2  additional  patents  pending  on the  laser
rangefinder  product  line.  In  addition,  it has  licenses  on  patents to key
technologies  and software as well as an exclusive,  world-wide  license for the
PSIristor technology.


         The  Company  has a patent for a  nanosecond  pulse  generator  (planer
triode)  expiring in 2002,  and three  patents  for various  aspects of BASS(TM)
technology  expiring in 2001,  2005,  and 2006.  The Company was also  granted a
patent for its Bulk Avalanche  Semiconductor  Laser,  which expires in 2007. The
Company  also has a  non-exclusive  license to a U.S.  Patent that covers a bulk
avalanche device operating at cryogenic  temperatures that predates the BASS(TM)
patents.  Additionally,  the  Company has a patent  pending for its  E-OR230(TM)
laser  rangefinder  and a patent  pending for a SEEKER(TM)  GPR that the Company
developed for LandRay in its underground mining exloration  program.  Any patent
which issues on technology  developed  for  LandRay's  programs will be owned by
Power Spectra and licensed exclusively to LandRay.

         The patent positions of technology  companies such as Power Spectra are
uncertain and involve complex legal issues and factual questions.  No assurances
can be given that any future patent  applications  will issue as patents or that
any issued  patents  will  provide the Company  with  adequate  protection  with
respect to the covered  products,  technology,  or  processes.  Moreover,  it is
possible that other  companies may assert that their patents cover the Company's
technologies or expected products. If patents are issued to other companies that
contain claims that conflict with or cover the Company's technologies,  products
or expected products,  and such claims are ultimately determined to be valid, no
assurance can be given that the Company would be able to obtain  licenses to any
such patents on acceptable  terms,  if at all, or develop or obtain  alternative
non-infringing   technology.  In  addition,  there  can  be  no  assurance  that
litigation  will  not  be  initiated  against  the  Company  or  its  customers,
regardless  of  merit,  alleging  infringement  of  patents  held by  others  or
challenging the Company's  patents.  Such litigation could result in substantial
cost to and diversion of effort and management time by the Company,  which could
have a material adverse effect on the Company,  regardless of the results of the
litigation.

         In an effort to maintain  the  confidentiality  and  ownership of trade
secrets and other  confidential  information,  the Company  requires  employees,
consultants,  and certain collaborators to execute confidentiality and invention
assignment  agreements upon commencement of a relationship with the Company. The
agreements  are  intended  to enable the  Company to  protect  the  confidential
information  by the  disclosure and use of technology to which it has rights and
providing  for  ownership  by or  assignment  to  the  Company  of  confidential
technology developed at the Company or with the Company's  resources.  There can
be  no  assurance,  however,  that  these  agreements  will  provide  meaningful
protection for the Company's trade secrets or other confidential  information in
the event of unauthorized use or disclosure of such information.

         The Company does not believe that patents alone  represent the complete
body of knowledge required to duplicate or reverse engineer its products.  Power
Spectra  has  invested  over ten  years in  research  and  development  to fully
understand  and develop the proper  support  subsystems  and  processes  for its
products and technology. The Company believes that this understanding represents
a major competitive advantage.*

         The Company has filed  applications  for other patents  relating to its
GPR and electro-optical rangefinding systems technologies. There is no assurance
that such  patents  will issue or that the claims  included in any such  patents
will provide significant protection.

         As of December 31, 1997,  the Company's  backlog was  $450,000,  versus
$113,606 at December  31, 1996,  and  $801,261 at December 31, 1995.  The entire
backlog consisted of two incomplete  milestones under the LandRay  contract.  To
date the Company has  completed  all  milestones  under the LandRay  contract on
time. The Company expects to complete all of its current backlog within the next
twelve months.*

         Commercial sales of the Company's  products are typically made pursuant
to standard purchase orders that are cancelable without  significant  penalties.
In addition,  purchase orders are subject to price renegotiations and to changes
in quantities or products and delivery schedules caused by changes in customers'
requirements. As a result of the foregoing factors, the Company does not believe
that backlog at any given time is a reliable indicator of future sales.


Government Contract Matters

         Historically,  a material  portion of the  Company's  business has been
derived  from  contracts  with or for federal  government  agencies.  Government
contracts  generally provide for the termination or adjustment of material terms
of such  contracts at the election of the  government,  and the  government  may
pursue contractual, administrative, civil, and criminal remedies for improper or
illegal activities associated with obtaining and performing government contacts.
Administrative  remedies include the suspension,  debarment, or ineligibility of
all  or  part  of  a   company   from   receiving   government   contracts   and
government-approved  subcontracts. As is the case with any company that performs
material amounts of business with the federal government, any such action by the
government could have a material impact upon the Company's business.

         The Air Force  contract  expired  on June 1, 1996,  but the  Company is
subject to an audit by the Defense  Contract  Audit  Agency for  overhead  rates
applied to the  contract  for fiscal  years 1994,  1995 and 1996.  As such,  the
Company may be subject to  adjustments  up or down on contract  revenues.  While
such audits are commonplace,  the timetable for the audit is unknown at present,
and no assurances  can be given that such audit will not result in a significant
payment obligation to the government.


Environmental Compliance

         The  nature of the  business  subjects  the  Company  to a  variety  of
federal,  state,  and local  provisions  which  have  been  enacted  or  adopted
regulating  the  discharge  of  materials  into the  environment,  or  otherwise
relating to the  protection  of the  environment.  In  addition,  the Company is
responsible  for all  environmental  compliance  associated  with the  equipment
recently  acquired from Boeing,  including any  disposition  of such  equipment.
Although semiconductor  manufacturing has some inherent environmental risks, the
number and quantity of hazardous substances used at the Company's facilities are
minimal  and  should  pose  little or no  environmental  threat.* Some  parts of
specific  equipment  may be exposed  to  hazardous  substances,  but they can be
decontanimated or disposed of at sites designated to handle these materials. The
Company  believes the maximum  financial risk or expense for such disposal to be
less than $15,000.* The Company has not incurred any material operating expenses
nor been required to make any  significant  capital  expenditures to comply with
these  provisions.  Management  believes  that the Company is not subject to any
outstanding issues on past non-compliance,  and that the Company is currently in
compliance with all known  environmental  provisions.  However,  there can be no
assurance  that the Company will not become subject to  environmental  claims in
the future, the cost of which could be material.

Actual future  performance  may differ  materially  from the  Company's  current

Analysis of Financial  Condition and Results of  Operations - Factors  Affecting
Operating  Results"  for a  discussion  of  factors  that  could  affect  future

Research and Development

         For the fiscal years ending  December 31,  1997,  1996,  and 1995,  the
Company's  research  and  development  expenses  were  $798,478,  $714,368,  and
$213,667,  respectively.  See "Management's Discussion and Analysis of Financial
Condition and Results of Operations," for further discussion of this topic.


Employees

         As of December 31, 1997, the Company had 18 full-time  employees,  with
13 in  technical  positions  and 5 in  administrative  capacities.  None  of the
Company's  employees is represented by a labor union. The Company  considers its
relations  with its employees to be good. The Company's  success  depends on its
ability  to hire  and  retain  highly  specialized  engineers,  scientists,  and
management personnel, and competition for such personnel is intense.

         PSI has  reduced  internal  staff  costs  by  making  effective  use of
consultants  and  contract  personnel  on an "as needed"  basis.  The Company is
fortunate  to be  located  in an  area  where  highly  specialized  and  skilled
individuals are available on a contractual or consulting basis. The availability
of such  personnel  has  allowed  the  Company  to  continue  its  technological
development  in a highly  focused  manner  without  the  addition  of  permanent
headcount.


 ITEM 2. PROPERTIES

         The Company  leased 25,000 square feet of space from Boeing  located at
919 Hermosa  Court,  Sunnyvale,  California,  under a  five-year  lease (with an
option to renew for a two-year  period) which  commenced  February 3, 1992,  and
ended in 1997. The Company  negotiated the renewal terms for one year at a fixed
rate and two years on a month to month basis at escalating  rates. In return for
below market rates for approximately 20 months, the Company granted an option to
the landlord to lease back up to 9,000 square feet or the entire  facility  upon
proper  notification.  Payments  under the lease in 1997 totaled  $268,368.  The
Company believes that,  based upon its dealings with the landlord,  the landlord
will not exercise its right to reclaim the entire  facility  during the month to
month  arrangement.  The Company believes that its current site is sufficient to
house the Company's  operations for the next twelve months,  regardless  whether
the option is exercised by the landlord.

         No cash  dividends on Common Stock have been paid by the Company  since
its inception.  The Company has no plans for payment of cash dividends on Common
Stock in the foreseeable future, and intends to retain its earnings, if any, for
the  development of its business.  The Company is required to pay cash dividends
on its Series A Preferred  Stock  issued in 1994,  and on its Series B Preferred
Stock issued in 1995.  Dividends  payable on both series of the Preferred  Stock
for the 1997 fiscal year were $192,604.

         In the fourth quarter of 1997, the Comapny issued  3,200,000  shares of
its common stock to certain investors.  (see Management Discussion and Analysis,

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS

This Report contains  forward-looking  statements  within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934.  Actual  results could differ  materially  from those  projected in the
forward-looking  statements as a result of various  factors,  including the risk
factors set forth under the heading  "Factors  Affecting  Operating  Results" on
page 21 of this Report and  elsewhere in this Report.  The Company has attempted
to  identify  forward-looking  statements  by  placing an  asterisk  immediately
following the sentence or phrase that contains the forward-looking statement.

Results of Operations

         1997 Compared to 1996

         Revenues for the year ended December 31, 1997 were $942,128, which were
$57,986 less than revenues of $1,000,114 for the prior year. The decrease in the
Company's  revenues in 1997 compared to 1996 was primarily due to the completion
of the Air Force Contract in 1996.  After  adjustments for the lack of Air Force
Contract  revenues,  1997 results reflect an actual increase in new contract and
commercial product revenues, mainly attributable to LandRay contract revenues.

         The  revenue  recognized  from  the  Company's  Phase  1  and  Phase  2
development  contractual efforts with LandRay accounted for $750,000,  or 80% of
the Company's  revenues in 1997,  compared to $550,000,  or 55% of the Company's
revenues in 1996.  During 1997, due to the Company's shift in business focus and
the resultant new GPR technology  development efforts, the Company was unable to
add  significant  new contract  revenues other than for the LandRay GPR product,
and as a result,  although operating expenses were reduced 31% from 1996 levels,
the Company's results of operations, and financial condition have not materially
improved.

         The net  loss for the  year  ended  December  31,  1997 was  $2,647,399
compared to a net loss of $3,788,299 in 1996.  After adjustment for dividends on
Preferred  Stock of  $192,604,  the net loss  applicable  to common  shares  was


                                       18
<PAGE>

$2,840,003  or $0.14 per share as  compared  with a net loss for the year  ended
December 31, 1996 of $3,983,752, or $0.26 per share.

         Cost of revenues decreased by $861,041, or 33% from 1996 levels, due to
personnel  and  associated  fringe  benefit  reductions,  lower  consulting  and
contract labor  expenditures,  reduced  overhead, materials and outside services
purchases.

         Sales and marketing  costs decreased as compared to 1996 by $248,112 or
66% due to personnel  reductions,  and reduced  travel,  advertising  and public
relations  expenses.  Research and development costs increased by $84,110 or 12%
primarily due to increased GPR technology  development  and increased  PSIristor
switch process development efforts which resulted in production yields in excess
of anticipated 1998  requirements.  General and  administrative  costs decreased
from  1996 by  $246,290  or 20% due  principally  to lower  severance  expenses.
Approximately 75% of this decrease was related to extraordinary personnel costs,
particularly severence, incurred in 1996.

         1996 Compared to 1995

         Revenues for the year ended  December 31, 1996 were  $1,000,114,  which
were $429,511 less than revenues of $1,429,625  for the prior year. The decrease
in the  Company's  revenues  in 1996  compared  to  1995  was  primarily  due to
expiration of the Air Force Contract on June 1, 1996, which provided $814,285 of
revenue in 1995, and $242,279 of revenue in 1996.

         The revenue  recognized under the Air Force Contract  accounted for 24%
of the Company's revenue in 1996 and 57% in 1995.  Revenues  recognized from the
Company's  Phase 1 development  effort with the LandRay joint venture  accounted
for $550,000 or 55% of the Company's  revenues in 1996. During 1996, the Company
was unable to add significant new contract  revenues other than from the LandRay
joint venture, which were a direct result of the shift in the Company's business
direction  in  mid-1996,  and as a  result,  although  operating  expenses  were
reduced,  the Company's  results from  operations  and financial  condition were
adversely affected.

         The net loss for the  year  ended  December  31,  1996 was  $3,788,299,
compared to a net loss of $2,562,230 in 1995.  After adjustment for dividends on
Preferred  Stock of  $195,453,  the net loss  applicable  to common  shares  was
$3,983,752  or $0.26 per share as  compared  with a net loss for the year  ended
December 31, 1995 of 2,751,425 or $0.25 per share.

         Sales and  marketing  expenses were  $374,469 in 1996,  representing  a
decrease of $120,335 or 24% relative to sales and marketing expenses of $494,804
in 1995. Due to a reduced emphasis on government  contract  revenues,  personnel
costs associated with marketing to government programs declined, while marketing
expenditures related to the Company's industrial and standard products continued
in 1996 in an attempt to establish a market for such products.

         Research  and  development  costs  increased  by  $500,701  in  1996 to
$714,368 from $213,667 in 1995, a 334% increase,  primarily because of increased
technical  consulting  costs  due to the  Company's  redirection  to  industrial
sensing products and ground penetrating radar applications.

         General and  administrative  expenses  increased  by 13% or $140,880 in
1996 to $1,203,469 from $1,062,589 in 1995 primarily due to increased  personnel
costs.

         The  Company  had no  interest  expense in 1996  compared  to  interest
expense of  $18,126 in 1995,  which was due to  short-term  financing.  Interest
income increased by $57,469 or 155% to $94,552 in 1996 from $37,083 in 1995 as a
result of the short term  investment of cash reserves which increased due to the
completion of a private placement of Common Stock in March, 1996.


         Liquidity and Capital Resources


                                       19
<PAGE>

         Working capital at December 31, 1997 was a negative  $349,011  compared
to a positive  $212,998 at December  31,  1996,  a decrease  of  $562,009.  This
decrease was due primarily to net operating loss $2,647,399  partially offset by
the net  proceeds  of  $2,090,549  from the sale of Common  Stock in the  first,
second and fourth  quarters  of 1997.  At  December  31,  1997,  the Company had
$441,254 in cash and cash equivalents.

         The  Company  completed  an  offering  of its  Common  Stock with gross
proceeds to the Company of $1,092,500 on April 10, 1997. Another offering of the
Company's  Common  Stock with gross  proceeds to the Company of  $1,200,000  was
completed on November 11, 1997.

         On April 10, 1997,  the Company issued  4,370,000  shares of its Common
Stock to certain investors,  for a aggregate gross purchase price of $1,092,500.
The investors  included  entities  affiliated  with the Travelers  Group,  which
purchased  2,000,000  shares for an aggregate  purchase  price of $500,000.  The
Company  employed  multiple parties as placement agents in connnection with this
transaction.  The Company  agreed to pay the selling agents a cash placement fee
equal to 5% of the gross proceeds of the transaction.  In addition,  the Company
agreed  to issue to the  selling  agents  warrants  exercisable  for a number of
shares of Common  Stock  equal to 5% of the total  number of shares  sold in the
offering.  The Common Stock was issued without registration under the Securities
Act in  reliance  on  Section  4(2)  of the  Securities  Act  and  Regulation  D
promulgated thereunder.

         On  September  30, 1997,  October 31, 1997 and  November 13, 1997,  the
Company  issued an aggregate of 3,200,000  shares of its Common Stock to certain
investors,  for an aggregate  gross purchase  price of  $1,200,000.  The Company
employed  Morgan Fuller Capital Group as placement agent in connection with this
transaction.  The Company  agreed to pay the selling agent and its  sub-agents a
cash  placement fee equal to 8% of the gross  proceeds of the  transaction.  The
Company  has agreed to issue to the selling  agent  warrants  exercisable  for a
number of shares of Common  Stock equal to 5% of the total number of shares sold
in the offering.  In addition,  in recognition of financial  consulting services
previously rendered, the Company has agreed to sell the selling agent additional
five-year  Common  Stock  purchase  warrants,  entitling  the holder  thereof to
purchase up to an aggregate of an additional  160,000  shares of Common Stock at
an exercise price of $0.375 per share.  The purchase price for these warrants is
$400.  The Company has agreed to register  for resale the shares of Common Stock
issued in the private placement, as well as the shares issuable upon exercise of
the selling  agent's  warrants.  The  placement  agreement  provided that if the
Company  fails to file and have the  registration  effective  within 120 days of
November 13, 1997,  the Company would be obligated to pay the purchasers of this
placement an  additional  2% of shares  purchased  and that the Company would be
further  obligated to pay an additional 2% of shares purchased in this placement
for each 30 day period delay until such registration becomes effective. Pursuant
to such provisions, the Company will issue an additional 128,000 shares to these
investors in April, 1998. The Common Stock was issued without registration under
the  Securities  Act in  reliance  on  Section  4(2) of the  Securities  Act and
Regulation D promulgated thereunder.

         Accounts  receivable  at December 31, 1997  increased by $193,106  over
year-end 1996, while unbilled accounts decreased by $25,813 over the same period
for a net  increase of $167,293.  The large net increase in accounts  receivable
principally  reflects a billing to LandRay  resulting  from the  completion of a
contract milestone in the fourth quarter 1997.

         Inventories   increased  by  $14,624  over  1996  year-end  levels  due
primarily to completion  of  sub-assemblies  for the  Company's  electro-optical
product line and ground  penetrating  radar.  Other current assets  decreased by
$19,444  primarily  as a result of  timing  of  payments  on  various  insurance
contracts.

         Accounts payable  increased by $149,506 over 1996 year-end levels, as a
result of the timing of vendor payments  related to the Company's annual holiday
plant closure.  Accrued compensation expense decreased by $17,332 primarily as a
result of personnel using accrued  vacation in conjuction with the holiday plant
closure and a reduced number of personnel.

         Preferred  stock  dividends  payable  increased by $192,604  over 1996.
During  1997,  the Company did not meet  California  statutory  criteria for any
dividend distributions.

         The Company's  current cash position,  together with  anticipated  cash
flows  from  operations  and new debt or  equity  financings,  are  expected  by
management to be sufficient to finance the Company's operations through December
31, 1998.  However,  the actual amount of time that the Company's cash resources
last is dependent  upon


                                       20
<PAGE>

a variety of  factors  including  the timing of  obtaining  new  contracts,  the
resources applied by the Company to continued product development, timing of new
financings,  success of its current joint venture,  and  competition  with other
vendors.  If the Company  determines that it requires  additional funds prior to
December  31,  1998,  there can be no assurance  that  additional  funds will be
obtainable on reasonable  terms, if at all. Any additional  equity financing may
adversely  affect  the  rights and  preferences  of,  and result in  significant
dilution to, existing  stockholders.  Any failure to obtain adequate  additional
funding could result in the Company  becoming  unable to meet its obligations as
they come due.  Unless the  Company is  successful  in adding  new  revenue  and
replacing the revenue and cash flow recently  generated by the LandRay contracts
and the Air Force Contract, the Company would continue to experience significant
operating  losses.  As a result of the  accumulated  substantial  losses in past
years and the additional  capital required to complete  product  developments of
current  proposed  product  offerings  and  to  extend  its  technology  to  new
applications,  the Company's  auditors have issued a modified audit report as to
the Company's  ability to continue as a going  concern,  on the  Company's  1997
financial statements.

         The  Company's  strategy  includes  the  successful  completion  of GPR
products  under  development,  development  of  new  product  applications,  and
development of new marketing  strategies.  The Company  continues its efforts to
seek new  strategic  partner(s)  and/or  debt or equity  investors.  There  can,
however,  be no assurances that the Company will be able to successfully  obtain
additional  financing  or  strategic  partners,  or that  the  terms of any such
financing or partnership would be favorable to the Company.


         FACTORS AFFECTING OPERATING RESULTS

         Power  Spectra  operates  in a rapidly  changing  environment  which is
subject  to  numerous  risks and  uncertainties,  many of which are  beyond  the
Company's control.  Moreover,  this Report contains  forward-looking  statements
that involve risks and uncertainties. The Company's actual results of operations
could  differ  materially  from  those  anticipated  in  these   forward-looking
statements  as a result of  certain  factors,  including  those set forth in the
following risk factors and elsewhere in this Report.

         History  of  Losses;  Accumulated  Deficit.  Since its  inception,  the
Company has generally  operated at a loss since  government  contract  revenues,
which  represent  most of the  historical  revenues  of the  Company,  and other
sources  of  income  were  insufficient  to cover  general  and  administrative,
research and  development  and other costs incurred by the Company.  The Company
recorded net losses of $2,647,399, $3,788,299 and $2,562,230 for the years ended
December 31, 1997,  December  31, 1996 and December 31, 1995,  respectively.  At
December  31,  1997,  the Company had an  accumulated  deficit of  approximately
$17,902,959 and a working capital deficit of $349,011.  The Company expects that
it  will  continue  to  incur  losses  until  its  contract   revenues  increase
substantially  from current levels or the Company begins to receive  significant
product sales and license and/or royalty income.  There is no assurance that the
Company will achieve profitable operations in the foreseeable future, if at all.
Although the Company has  substantially  reduced the size of its operations over
the last two years,  there can be no assurance  that the Company's  revenues and
proceeds from the equity  financings  will be sufficient to allow the Company to
support its operating expenses.

         Dependence on LandRay Contract. The Company's relationship with LandRay
Technology,  Inc.  ("LandRay") has been the Company's primary source of revenues
since the first  contract  was  awarded to the  Company in 1996.  The  Company's
relationship with LandRay was an extremely significant source of revenues during
1996 and 1997, and is expected to remain  significant for the forseeable future.
The  Company  recognizes  revenue  from its  contract  with  LandRay  based upon
attainment of milestones delineated in the contract. Unless the current contract
with LandRay is extended,  it will be necessary to find  alternative  sources of
revenue,  and there is no  assurance  that the Company  would be  successful  in
accomplishing this result.

         Need to Successfully Launch and Fund New Ventures. The Company believes
it must  continue  to seek and obtain  other  sources  of  revenue  to  continue
operations.  Since its inception nearly all of the Company's  revenues have come
from defense-related  research and development contracts related to the BASS(TM)
development and  applications.  The Company  currently is seeking to exploit its
technology for applications in commercial and industrial markets to provide such
revenue.  During 1996, the Company  entered into two ventures,  LandRay and PEAC
Airborne Technologies in order to develop and exploit new business opportunities
which the Company  believes are possible  based upon its  ultra-wideband  ground
penetrating  radar  ("UWB  GPR")  technology.  As of the


                                       21
<PAGE>

date hereof,  the PEAC venture has been  suspended.  The LandRay venture and any
future ventures will require  significant funding in order to enable the Company
and its strategic  partners to carry out their  respective  plans of operations.
There  can be no  assurances  that  the  LandRay  venture  will be able to raise
adequate  funding  on  acceptable  terms,  that  the  Company  will  be  able to
successfully enter into any additional  suitable strategic  partnership or joint
venture arrangements or that such arrangements, when entered into, will prove to
be  beneficial  for the  Company  and its  shareholders.  There  also  can be no
assurance  that the proposed  joint venture  agreements,  if  consummated,  will
generate  sufficient  revenues to replace the existing  LandRay contract when it
expires.  Failure  to  succeed in one or more  strategic  partnerships  or joint
venture relationships could have a material adverse effect on the Company's plan
of operations and results.

         Need for Additional Capital. In order to meet its objectives, including
entering into additional  joint ventures,  the Company will require  substantial
additional  capital.  While the  Company  anticipates  attempting  to raise such
capital in the form of future private placements of its equity securities, there
can be no assurance that any such efforts will be successful,  that such capital
will be available on acceptable  terms, or at all. In addition,  any such equity
financing would be dilutive in ownership to existing investors and could involve
creation  of  rights  senior  to  existing  investors,   including  rights  upon
liquidation  or sale of the  Company.  The  failure of the  Company to  complete
additional  financings in the future would have a material adverse effect on the
Company's business, financial condition and results of operations.

         Expiration  of Air Force  Contract.  The  Company's  contract  with the
United States Air Force expired in June 1996 and final payments  thereunder were
received by the  Company  during  1996.  With the  termination  of the Air Force
Contract,  the Company has found it necessary  to shift its focus to  industrial
products to find alternative sources of revenue,  and there is no assurance that
the Company will be successful in accomplishing  this result.  If the Company is
not  successful  in  replacing  the revenue and cash  generated by the Air Force
contract,  the Company will continue to experience  significant operating losses
and  significant  negative  cash flow.  Although  the Company has  substantially
reduced the size of its operations  since  expiration of the Air Force Contract,
there can be no assurance  that the Company's  revenues and proceeds from equity
financings,  if any,  will be  sufficient  to allow the  Company to support  its
operating  expenses.  The Air Force  contract  expired on June 1, 1996,  but the
Company is subject to an audit by the Defense Contract Audit Agency for overhead
rates applied to the contract for fiscal years 1994, 1995 and 1996. As such, the
Company may be subject to  adjustments  up or down on contract  revenues.  While
such audits are commonplace,  the timetable for the audit is unknown at present,
and no  assurances  can be given that such audit will not result in  significant
payment obligation to the government.

         Product  Development and  Enhancements.  The development of GPR systems
and other remote sensing products as well as high power switching components and
products is a complex  engineering effort involving  significant risk. While the
Company   believes  it  has  completed   development  of  its  core  technology,
significant  additional  development  efforts  must be made in order to  achieve
commercial  acceptance  of its products.  Such efforts will require  substantial
additional  capital,  the  source and  timing of which is  unknown.  There is no
assurance  that the Company will succeed in raising the needed capital or in the
product development efforts, even if the necessary funding is raised.

         Complex Manufacturing Process;  Manufacturing Capacity. The manufacture
of GPR systems and remote sensing products as well as semiconductor-based  power
switching  devices is highly complex and sensitive to a wide variety of factors,
including the level of contaminants in the manufacturing environment, impurities
in the materials  used and the  performance  of personnel as well as vendors and
suppliers.  The Company has periodically  experienced yield problems,  and there
can be no assurance  that these  problems  will not reoccur.  Should the Company
experience   protracted   production   delays   attributable  to   manufacturing
complexity, its ability to deliver products would be materially affected. In the
event that the Company commences  significant  commercial  shipments,  it may be
required to obtain third party manufacturing services.

         Dependence  on  Facilities.  The Company  does not expect to be able to
remain in its current facilities in the long-term. Appropriate manufacturing and
executive  office space in Silicon  Valley is extremely  limited and there is no
assurance that the Company will be able to secure  adequate  facilities on terms
that are  acceptable to the Company,  if at all. This  circumstance  could cause
delays in the manufacture and delivery of the Company's  products and could have
a material adverse impact on the Company's results of operations.


                                       22
<PAGE>

         Dependence on Government  Contracts;  Limited Commercial Sales to Date.
Historically,  a  material  portion  of the  Company's  business  resulted  from
contracts with or for government  agencies.  The Company expects that dependence
on such contracts for a portion of its revenues will decline in the  foreseeable
future. Government contracts generally provide for the termination or adjustment
of material terms of such contracts at the election of the  government,  and the
government may pursue contractual,  administrative,  civil and criminal remedies
for improper or illegal  activities  associated  with  obtaining and  performing
government contracts.  Administrative remedies include suspension,  debarment or
ineligibility  of all or part of a company from receiving  government  contracts
and  government-approved  subcontracts.  Any such action by the government could
have a material adverse impact upon the Company's  business.  Moreover,  general
political  and  economic  conditions,  which  cannot  be  accurately  predicted,
directly and indirectly  affect the quantity and allocation of  expenditures  by
governmental  agencies.  Therefore,  cutbacks in the federal budget could have a
material  adverse  impact on the Company's  results of operations so long as the
Company remains dependent on government contracts. Notwithstanding the fact that
the  applicability  of both the  Company's  BASS(TM)  and  PSIristor(TM)  device
technology   to  ground   penetrating   radar   systems  has  been   technically
demonstrated,  with the exception of development contract revenues from LandRay,
at this early stage of its shift in strategic  business  focus,  the Company has
not yet generated  significant  revenues from sales of its commercial  products.
The first GPR product developed for LandRay,  the SEEKER(TM),  is just currently
entering initial production.  In addition,  the previous sections of this report
discuss  potential  future  products  and  applications  of the  Company's  core
technologies which the Company is considering  pursuing,  but which have not yet
been  developed,  tested or deployed.  There can be no assurance that any of the
commercial  products discussed below will be successfully  developed or accepted
in their  target  markets,  that  revenues  generated by such  products  will be
sufficient  to return the cost of their  development,  that the Company  will be
successful in  developing  additional  new  products,  that the Company will not
experience  delays in  developing  such  products,  or that such  products  will
achieve commercial success. A sustained failure to successfully develop and sell
new products would have a material adverse effect on the Company's  business and
its results of operations.

         Limitations  on  Protection  of  Intellectual   Property.  The  Company
believes  its  ability  to  compete  effectively  with  other  companies  may be
materially  dependent  upon the  proprietary  nature  of its  technologies.  The
Company  holds a number of  domestic  patents  covering  various  aspects of its
BASS(TM) technology but has no patents pending on its PSIristorTM  technology as
it was  transferred  from Russia,  and the Company holds an exclusive  worldwide
license for its manufacture and use outside the former Soviet Union. The Company
has applied for  multiple  patents on its GPR system,  the  SEEKER(TM),  and the
Electro-Optical  Rangefinder,  E-OR 230(TM).  To date,  one patent each has been
granted on these  devices and several  more are  pending.  There is no assurance
that any additional patents will be granted to the Company or that the Company's
patents will provide meaningful protection from competition. Moreover, there can
be no  assurance  that any patents  will be upheld by a court should the Company
seek to enforce its rights  against an  infringer  or that the Company will have
sufficient  resources to prosecute  its patent and other  intellectual  property
rights. Furthermore, issuance of a valid patent does not prevent other companies
from independently developing technology similar to the Company's, and there can
be no assurance that any particular aspect of the Company's  technology will not
be found to infringe the claims of other existing patents. In addition to patent
protection,  the Company relies to a significant extent on proprietary  know-how
and trade  secrets  particularly  with  respect to its  PSIristor(TM),  which it
considers a highly proprietary invention.

         Limited  Sales  and   Marketing   Capability;   Future   Reliance  upon
Distributors.  The Company  currently has no marketing staff or salesforce.  The
Company will be required to establish such marketing and sales staff in order to
execute its plans for  increasing  commercial  sales.  In addition,  in order to
materially increase revenues and achieve sustained profitability (of which there
is no  assurance) as the Company  continues to  commercialize  its products,  it
expects  that it  will be  required  to  depend  upon  distributors.  While  any
particular distributor may have an extensive distribution network,  distributors
typically represent other third-party  suppliers,  including  competitors of the
Company,  to whom they may devote greater time, effort and attention.  There can
be no  assurance  that the Company will  successfully  establish  the  requisite
distribution  relationships or that those relationships will result in increased
revenues.

         Competition. The markets for the Company's products are competitive and
characterized by rapid  technological  change and changes in market demand.  The
Company's  competitive  position  is  affected  by all of these  factors  and by
industry  competition  for  effective  sales  and  distribution   channels.  The
Company's potential and existing  competitors include major ultrasonic proximity
sensor  vendors,  a small  number  of which  dominate  the  market.  Most of the
Company's competitors have substantially greater financial, technical, marketing
and other


                                       23
<PAGE>

resources  than does the  Company.  The Company  expects  that its markets  will
become  more  competitive  in the  future,  and there is no  assurance  that the
Company  will be able to  successfully  compete  in its  selected  markets.  See
"Business - Competition."

         Ability to  Continue  as a Going  Concern.  The  Company's  independent
accountants,  in their report regarding the Company's  financial  statements for
the year ended December 31, 1997, have included an explanatory  paragraph noting
that  the  Company's   recurring   substantial   losses  from  operations  raise
substantial  doubt about the Company's  ability to continue as a going  concern.
The ability of the Company to continue as a going concern is contingent upon its
ability to secure  additional  financing,  as to which the Company currently has
plans but no specific or definitive commitments. There  is no assurance that the
Company  will be able to secure  adequate  financing or to carry out its current
business plan.

         Volatility of Stock Price.  The market price of Company's  Common Stock
is  highly  volatile  as the  stock is  thinly  traded.  Other  factors  such as
variations in the Company's operating results and announcements of technological
innovations or price reductions by the Company,  its competitors or providers of
alternative  products  and  processes  may cause the market  price of the Common
Stock  to  fluctuate.   In  addition,   the  securities  markets  have  recently
experienced  substantial  price and volume  fluctuations  that have particularly
affected technology-based companies and resulted in changes in the market prices
of the  stocks of many  companies  that have not been  directly  related  to the
operating  performance  of those  companies.  The price of the Company's  Common
Stock is particularly susceptable to extreme fluctuation because of thin trading
volume in the Common Stock and lack of widely available pricing information.

         Year 2000  Compliance.  Many currently  installed  computer systems and
software  products are coded to accept only  two-digit  entries in the date code
field.  Beginning  in the year 2000,  these date code fields will need to accept
four-digit entries to distinguish 21st century dates from 20th century dates. As
a result,  in approximately  eighteen  months,  computer systems and/or software
used by many  companies  may need to be upgraded to comply with such "Year 2000"
requirements.  Significant  uncertainty  exists concerning the potential effects
associated with compliance.  Although the Company believes that its systems will
be Year 2000  compliant,  there can be no assurance  that coding errors or other
defects will not be discovered in the future.  Any Year 2000 compliance  problem
of the  Company,  its  customers  or its  suppliers  could  result in a material
adverse  effect on the Company's  business,  financial  conditions and operating
results.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING
         AND FINANCIAL DISCLOSURE

         On January 19, 1996, the Company dismissed the accounting firm of Ernst
& Young LLP,  which had  previously  been engaged as the  Company's  independent
accountant to audit the Company's financial statements.  Ernst & Young's reports
on the Company's  financial  condition  for the fiscal years ended  December 31,
1993 and December 31, 1994 did not contain any adverse  opinion or disclaimer of
opinion,  and such  reports  were not  otherwise  modified  or  qualified  as to
uncertainty,  audit scope or accounting principles, except that Ernst & Youngs's
report on the Company's  financial  condition for the fiscal year ended December
31, 1994 contained a going concern qualification.  Furthermore, to the knowledge
of current management, during the 1994 and 1995 fiscal years, the Company had no
disagreements  with  Ernst & Young on any  matter of  accounting  principles  or
practices, financial statement disclosure, or auditing scope or procedure, which
disagreements,  if not resolved to the satisfaction of Ernst & Young, would have
caused  it to make  reference  to the  subject  matter of the  disagreements  in


                                       24
<PAGE>

connection  with its  report(s).  The  decision  to  dismiss  Ernst & Young  was
approved by the Company's Board of Directors.

         On January 19, 1996 the Company  retained the accounting  firm of Grant
Thornton  LLP as its  principal  accountant  to audit  the  Company's  financial
statements.

         No executive  officer of the Company serves as a member of the Board of
Directors  or  Compensation  Committee  of any  entity  which  has  one or  more
executive  officers  serving as a member of the Company's  Board of Directors or
Compensation Committee.

Employee and Director Benefit Plans

         The  following  is a brief  summary of plans in effect  during the Last
Fiscal  Year under  which  officers,  directors  and  employees  of the  Company
received benefits.

         1986 Stock Option Plan. The Company's 1986 Stock Option Plan (the "1986
Plan")  was  adopted  by the  Company's  Board of  Directors  in March  1987 and
approved by the Company's  shareholders in October 1987. A total of 1,690,000 of
Common Stock was reserved for issuance under the Option Plan.

         The 1986 Plan is administered by the Board of Directors,  which has the
authority to select the  employees  and  consultants  of the Company  (including
officers  and  employee  directors)  who are to  receive  option  grants  and to
determine  whether  each  option  granted  is to be an  incentive  stock  option
satisfying  the  requirements  of Section 422A of the  Internal  Revenue Code of
1986, as amended,  or a nonstatuatory  stock option.  The exercise price of each
incentive  stock  option  granted  may not be less than 100% of the fair  market
value of the  Company's  Common  Stock on the date of the grant and the exercise
price of a  nonstatuatory  option  may not be less  than 85% of the fair  market
value of the Company's Common Stock on the date of the grant. No option may have
a term in  excess  of ten years  measured  from the date of grant.  The Board of
Directors  selects  the  optionees,  the  number of shares to be subject to each
option and the vesting period of options  granted under the 1986 Plan. In making
such  determination,  the Board of  Directors  takes into account the duties and
responsibilities of the employee or consultant, as the case may be, the value of
the optionee's  services,  his or her present and potential  contribution to the
success of the Company  and  anticipated  number of years of future  service and
other relevant factors.

         The 1986 Plan  expired as to future  grants  upon  adoption of the 1996
Stock Plan in June, 1996.

         1996 Stock  Plan.  The Board of  Directors  adopted the 1996 Stock Plan
(the  "1996  Plan") in April  1996 and the Plan was  approved  by the  Company's
shareholders  in June 1996.  A total of  1,500,000  shares of Common  Stock were
reserved for issuance upon  exercise of options  granted under the 1996 Plan, in
addition to the shares which  remained  available  for  issuance  under the 1986
Plan.  The plan provides for grants in a manner  similar to the 1986 Plan and is
not a deferred  compensation  plan under  Section  401(a) of the Code and is not
subject to the  provisions of ERISA.  In accordance  with Section  162(m) of the
Code, the 1996 Plan imposes a limitation on grants to any optionee in any fiscal
year so that the aggregate grants in any one year to any optionee may not exceed
300,000 shares per fiscal year,  provided,  however,  that new hires may receive
additional  option  grants for no more than 300,000  shares in the year they are
hired.  In addition,  there is a limit of $100,000 on the aggregate  fair market
value of shares subject to all Incentive Stock Options which are exercisable for
the first time in any calendar year by an employee.

         The 1996 Plan  provides  that,  in the event of a merger of the Company
with or into  another  corporation,  the sale of more than fifty perent (50%) of
the Company's voting stock, a sale of substantially  all of the Company's assets
or a liquidation  or  dissolution  of the Company  ("Transfer of Control"),  the
acquiring  or  successor  corporation  may  assume or  substitute  substantially
equivalent  awards for the  awards  outstanding.  To the  extent  awards are not
assumed or  substituted  for,  they will vest in full prior to the  Transfer  of
Control.  To the extent options are not assumed,  substituted  for, or exercised
prior to the Transfer of Control, they will terminate.

         1991 Director  Stock Plan.  The Company's 1991 Director Stock Plan (the
"Stock  Plan")  was  adopted  in  March  1991  and  approved  by  the  Company's
shareholders  in June 1991.  The Company  initially  reserved  100,000 shares of
Common  Stock for  issuance  under the Stock  Plan.  The  shareholders  approved
increases of 150,000 shares,  200,000 shares and 300,000 shares in the number of
shares  available for issuance under the Stock Plan in June 1993, June 1995, and
June 1997,  respectively.  Under the Stock  Plan,  each  director  who is not an
employee or full-time consultant of the Company (an "Outside Director") receives
each quarter  $3,125 in shares of Common Stock of the Company  (based on a price
per share equal to the fair market  value of the Common Stock on the last day of
such quarter). The Company currently has six Outside Directors.

         1992  Director  Option Plan.  The  Company's  Director  Option Plan was
adopted  in  October  1992  by the  Board  of  Directors,  and  approved  by the
shareholders  in June,  1993. An aggregate of 230,000 shares of Common Stock was
reserved for issuance under the 1992 Director Option Plan (the "Director  Option
Plan").   Under  the  1992  Director  Option  Plan  each  Outside   Director  is
automatically granted an option to purchase 10,000 shares each year on the third
trading day following the public announcement of the Company's financial results
for  the  preceeding  fiscal  year.  Only  Outside  Directors  are  eligible  to
participate in the Director Option Plan. The  shareholders  approved an increase
of  170,000  shares in the number of shares  available  for  issuance  under the
Director  Option Plan in June 1996.  Each  Outside  Director  was  automatically
granted an option for 10,000  shares in March 1997.  Options  granted  under the
Director Option Plan are nonstatutory  options, and do not qualify as "incentive
stock options," as defined in Section 422 of the Internal  Revenue Code of 1986,
as amended.

               Report of Independent Certified Public Accountants





Board of Directors and Stockholders
Power Spectra, Inc.

We have  audited  the  accompanying  balance  sheets of Power  Spectra,  inc. (a
California  corporation)  as of  December  31,  1997 and  1996  and the  related
statements of operations,  stockholders'  equity, and cash flows for each of the
three years in the period ended December 31, 1997.  These  financial  statements
are the  responsibility of the Company's  management.  Our  responsibility is to
express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the  financial  position of Power  Spectra,  Inc. as of
December 31, 1997 and 1996, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1997, in conformity
with generally accepted accounting principles.

The  accompanying  financial  statements  have been  prepared  assuming that the
Company will continue as a going concern. As shown in the financial  statements,
the Company has accumulated  substantial losses in recent years and will require
additional  capital to complete product  development of current proposed product
offerings and extend its technology to new  applications.  These factors,  among
others,  as discussed in Note 2 to the financial  statements,  raise substantial
doubt about the Company's  ability to continue as a going concern.  Management's
plans in regard to these  matters are also  described  in Note 2. The  financial
statements do not include any adjustments  that might result from the outcome of
this uncertainty.

                          Notes to Financial Statements

                                December 31, 1997

1.  The Company and summary of significant accounting policies

The  Company  develops,  designs,  and  markets  a family of  products  that use
proprietary  high speed  semiconductor  devices which generate  extremely rapid,
high-power  electromagnetic  impulses.  The  primary  business of the Company is
related to the Bulk Avalanche Semiconductor Switch (BASS(TM)) and PSIristor(TM).
These switches have applicability in high-resolution radar,  electronic warfare,
communications, and industrial applications such as ground penetrating radar for
use in geophysical exploration, underground mapping, and site remediation, level
control,   positioning,   velocity  measurement,   and  obstacle  detection  and
avoidance.  Historically,  over 90% of the  Company's  revenues  have  come from
research and development  contracts principally with U.S. Government agencies or
its contractors.

In  preparing  financial   statements  in  conformity  with  generally  accepted
accounting  principles  (GAAP),  management  is required to make  estimates  and
assumptions  that affect the reported  amounts of assets and liabilities and the
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements,  and revenues  and  expenses  during the  reporting  period.  Actual
results could differ from these estimates.

The    Company    accounts    for   its    long-term    contracts    using   the
percentage-of-completion  method when appropriate. For other long and short term
research and development  contracts  which call for meeting  certain  milestones
specified  in  those  contracts  for  which  certainty  of  delivery  cannot  be
preordained, the Company expenses costs as incurred and recognizes revenues only
upon  completion of those  milestones.  The Company had one  long-term  contract
whose final  deliverable  was completed in the second quarter of 1996. A reserve
of $100,000 has been set up to handle any contingencies,  which at this time are
unknown, related to this contract.

1.  The Company and summary of significant accounting policies (continued)

Patents

The cost of patents is being  amortized  over their  statutory  lives  using the
straight-line method.

Investment in affiliate

The Company  accounts for its investment in LandRay  Technology,  Inc. using the
equity method of accounting. The Company's cost basis in the investment is zero.
The excess of the Company's  proportionate share of the net assets over its cost
basis,  approximately  $25,000 at inception of the joint  venture,  has not been
reflected  in income.  The  resultant  credit  has been  reflected  as  negative
goodwill.  The two amounts offset for financial statement presentation purposes.
Likewise,  any proportionate share of losses incurred by LandRay has been offset
by an identical amount of amortization of negative goodwill. The Company has not
guaranteed any obligations of LandRay and,  therefore has not recognized any net
losses  which would  reduce its net  investment  in LandRay  below  zero.  As of
December 31, 1997, the Company held an approximate 31% stake in LandRay,  making
the Company the largest single shareholder.

Revenue from affiliate

The Company's  contract  with LandRay calls for the Company to provide  research
and  development  services to LandRay and to be compensated for such services as
the company achieves certain milestones as called for in the contracts for which
certainty of delivery cannot be preordained. Under this arrangement, the Company
expenses the research and development costs as incurred. Since LandRay currently
has no revenue generating  operations and funds required to meet its obligations
under the development contract have come entirely from various equity financing,
revenues are recognized only upon completion of those  milestones and only after
the Company is satisfied  that LandRay has the  resources to pay the amount due.
Therefore,  the Company  does not receive any advance  funding  from LandRay for
which it would be liable to repay if the  milestone  is not met. The Company has
no  obligation  to repay any funds  received  from the LandRay  contracts.  Once
LandRay pays the Company,  LandRay has assumed the  financial  risk  involved in
that particular facet of the research and development.

Deferred Revenues

Deferred  revenues  are  payments  made by  customers  for which the Company has
deferred revenue  recognition  until the contract is closed out.  Contracts with
the  government  call for  audits of  overhead  rates for the years in which the
contract was  performed.  Currently the government has not audited for the years
1994, 1995, 1996, and 1997. No schedule has been set for these audits.

Income taxes

The Company accounts for income taxes using an asset and liability  approach for
financial accounting and reporting purposes.

Recent Issued Accounting Standards

In June 1997,  the  Financial  Accounting  Standards  Board issued SFAS No. 130,
Reporting  Comprehensive  Income, which requires that an entity report, by major
components  and  as  a  single  total,   the  change  in  its  net  assets  from
non-shareholder  sources during the period; and SFAS No. 131,  Disclosures About
Segments of an Enterprise and Related Information,  which establishes annual and
interim  reporting  standards  for an  entity's  business  segments  and related
disclosures about its products, services,  geographic areas and major customers.
Adoption of these statements will not impact the Company's  financial  position,
results of operations or cash flows.  Both  statements  are effective for fiscal
years beginning after December 15, 1997, with earlier application permitted.

                                      F-7

Loss per common share

In February 1997, the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting  Standards  No. 128 (SFAS 128),  "Earnings Per Share." The
Company has adopted SFAS 128 for all periods presented. The addition of SFAS 128
had no impact on previously reported loss per share for the 1996 and 1995 fiscal
years.  Under the provisions of SFAS 128, primary earnings per share is replaced
by basic earnings per share and the dilutive effect of stock options,  warrants,
convertible  stock,  and  contingent  stock  issuances  are  excluded  from  the
calculation.   For  companies  like  Power  Spectra  with  potentially  dilutive
securities  such  as  stock  options,   warrants,   convertible  securities  and
contingent  stock  issuances,  fully  diluted  earnings per share is replaced by
diluted  earnings  per  share.  Loss per common  share is based on the  weighted
average of common shares outstanding for all periods  presented,  computed using
the net loss after deducting  Series A and Series B Preferred Stock dividends in
1997 and 1996,  and 1995.  The  assumed  exercise of options  and  warrants  and
assumed  conversion  of  convertible  securities  have not been  included in the
diluted loss per share computation as the effect would be anti-dilutive.

Cash and cash equivalents

The Company's cash and cash equivalents balance consists of bank demand deposits
and money market accounts,  none of which has a maturity over three months.  The
Company considers all highly liquid debt instruments  purchased with an original
maturity date of three months or less to be cash equivalents.

401(k) plan

The Company  has adopted a defined  contribution  plan under the  provisions  of
Section 401(k) of the Internal  Revenue Code covering all  employees.  Employees
may contribute to the plan and Company  contributions are determined annually by
the  Board  of  Directors.  For  the  year  ended  December  31,  1997,  Company
contributions to the plan were $13,735 (1996--$12,660; 1995--$12,457).


2. Going Concern

The  accompanying  financial  statements  have been prepared in conformity  with
generally accepted accounting principles,  which contemplate continuation of the
company as a going concern.  The Company has accumulated  substantial  losses in
recent years and has not commenced  revenue  producing  activities  from its new
product offerings in amounts  sufficient to fund current and future  operations.
The Company will require significant additional funding to both complete product
development  of current  proposed  product  offerings  and extend the use of its
technology to new applications. The Company,  to date has not raised  sufficient
funds to allow it to continue its present activities for the foreseeable future.

In view of the matters described in the preceding paragraph, recoverability of a
major portion of the recorded  asset amounts shown in the  accompanying  balance
sheet is dependent  upon continued  operations of the company,  which in turn is
dependent upon the company's ability to raise sufficient debt or equity to allow
the Company to complete  planned product  development  activities,  continue its
research  into new  applications  for its  technology  and succeed in its future
operations.  The financial statements do not include any adjustments relating to
the  recoverability and classification of recorded assets amounts or amounts and
classification  of  liabilities  that might be  necessary  should the company be
unable to continue in existence.

Management  is  continuing  its  efforts  to raise  additional  funding  through
issuance  of stock or debt in  amounts  sufficient  to fund  current  and future

3.  Series A Preferred Stock

In July 1993, the stockholders  approved an amendment to the Company's  Articles
of  Incorporation to create 5,000,000 shares of Preferred Stock, and the Company
designated  1,500 shares of the  Preferred  Stock as Series A. On September  30,
1993, the Company issued 1,044 shares of Series A Preferred Stock of the Company
in exchange for all of the  outstanding  Convertible  Debentures at a conversion
rate of one  share of the  Series A  Preferred  for  each One  Thousand  Dollars
($1,000)  principal amount of Debentures.  The holders of the Series A Preferred
are entitled to receive cumulative  dividends at the rate of 10% of the original
purchase  price of the  Series A  Preferred  per  annum,  payable  on a calendar
quarterly basis, in preference to any dividends on the Common Stock.

The Series A Preferred is convertible,  at the option of the holder, at any time
after the date of issuance, into shares of Common Stock at a conversion price of
$1.225.  Each share of the Series A Preferred  will be  automatically  converted
into  Common  Stock if at any time the holders of at least  sixty-seven  percent
(67%) of the  outstanding  Series A Preferred vote to convert all such Preferred
into Common Stock.

The  Series A  Preferred  is now  subject  to  redemption  at the  option of the
Company.  In the event that the Company  redeems  the Series A  Preferred  on or
before April 7, 1998, the redemption price will be equal to 106% of the original
purchase price of the Series A Preferred  ($1,000),  plus accumulated but unpaid
dividends to the date of redemption;  thereafter,  the redemption price shall be
equal to the  original  price of the Series A  Preferred  plus  accumulated  but
unpaid dividends at the date of redemption.

Each  holder of the  Series A  Preferred  has the  right to vote that  number of
shares equal to the number of shares of Common Stock issuable upon conversion of
such  holder's  Series A Preferred.  The Series A Preferred  shall vote with the
Common Stock on all matters,  except as may be required under applicable law and
as follows. The Company is precluded,  without first obtaining the approval of a
majority  of the  outstanding  shares  of the  Series A  Preferred,  voting as a
separate  class,  from  (1)  engaging  in any  merger,  consolidation,  sale  of
substantially all of its assets, or other reorganization in which the holders of
Series A Preferred  would not receive  their full  liquidation  preference;  (2)
declaring any dividends on the Common Stock (except  dividends payable solely in
Common Stock) while any Series A Preferred is  outstanding;  (3)  authorizing or
issuing shares of any class or series having rights,  preferences, or privileges
senior to the Series A Preferred  with  respect to  dividends,  liquidation,  or
redemption,  or issuing any  convertible  debt  instruments or debt  instruments
together with warrants  which if converted or exercised  would have a preference
or priority as to dividends,  liquidation,  or redemption senior to the Series A
Preferred; (4) amending the rights, preferences,  privileges, or restrictions of
the Series A Preferred;  or (5)  reclassifying any shares of Common Stock or any
other shares of capital stock into shares  having any  preference or priority as
to dividends, liquidation, or redemption superior to the Series A Preferred.

In the event of any liquidation or winding up of the Company, the holders of the
Series A Preferred  are  entitled to receive,  in  preference  to the holders of
Common Stock, an amount equal to the original  purchase price per share ($1,000)
of the Series A Preferred plus accumulated but unpaid dividends.

On December 31, 1995, 245 shares of the Series A Preferred  Stock were converted
into 200,013  shares of Common Stock and on July 9, 1996, 8 shares of the Series
A Preferred Stock were converted into 6,531 shares of Common Stock.

4.  Series B Preferred Stock

In September 1994, the Company designated 1,200 shares of the Preferred Stock as
Series B. The Company  closed new  financing of its Series B Preferred  Stock in
the aggregate  amount of $1,153,000  (1,153  shares) in 1995.  Costs incurred in
conjunction  with the Series B issuance totaled  $146,464,  of which $31,164 was
paid in cash for services,  and the remainder,  $115,300,  was paid in shares of
the Company's Common Stock at the Series B conversion price of $0.781 per share.
All  holders of the  Series B  Preferred  are  entitled  to  receive  cumulative
dividends  at the rate of 10% of the  original  purchase  price of the  Series B
Preferred per annum,  payable on a calendar  quarterly basis, after any dividend
payments  required to be made to the Series A Preferred Stock, and in preference
to any dividends on the Common Stock.

The Series B Preferred is convertible,  at the option of the holder, at any time
after the date of issuance, into shares of Common Stock at a conversion price of
$0.781 per share.  Each share of the Series B  Preferred  will be  automatically
converted  into Common Stock if at any time the holders of at least  sixty-seven
percent (67%) of the outstanding Series B Preferred approve the conversion.

The  Series B  Preferred  will be  subject  to  redemption  at the option of the
Company at any time on or after  January 13, 1997. In the event that the Company
redeems  the Series B Preferred  on or after  January  13,  1997,  but not after
January 13,  2000,  the  redemption  price will be equal to 106% of the original
purchase price of the Series B Preferred  ($1,000),  plus accumulated but unpaid
dividends to the date of redemption;  thereafter,  the redemption price shall be
equal to the  original  price of the Series B  Preferred  plus  accumulated  but
unpaid dividends to the date of redemption.

Each  holder of the  Series B  Preferred  has the  right to vote that  number of
shares equal to the number of shares of Common Stock  issuable upon  conversion.
The Series B Preferred Stockholders are entitled to vote with the holders of the
Series A Preferred  Stock and holders of Common Stock together as a single class
on all matters,  except as may be required under  applicable law and as follows.
The Company is precluded,  without first obtaining the approval of a majority of
the  outstanding  shares of the Series B Preferred,  voting as a separate class,
from (1) engaging in any merger, consolidation, sale of substantially all of its
assets, or other reorganization in which the holders of Series B Preferred would
not receive their full  liquidation  preference;  (2) declaring any dividends on
the Common Stock  (except  dividends  payable  solely in Common Stock) while any
Series B Preferred is  outstanding;  (3)  authorizing  or issuing  shares of any
class or series having rights, preferences, or privileges senior to the Series B
Preferred with respect to dividends,  liquidation, or redemption, or issuing any
convertible debt instruments or debt instruments together with warrants which if
converted or  exercised  would have a  preference  or priority as to  dividends,
liquidation,  or  redemption  senior to the Series B Preferred;  (4) amending or
repealing any  provision of, or adding any provision to, the Company's  articles
of   incorporation  or  by-laws  if  such  action  would  alter  or  change  the
preferences,  rights, privileges, or powers of, or the restrictions provided for
the  benefit  of,  the  Series B  Preferred  materially  and  adversely;  or (5)
reclassifying  any shares of Common Stock or any other  shares of capital  stock
into shares  having any  preference  or priority  as to  dividends,  liquidation
preference,  or redemption rights superior to any such preference or priority of
the Series B Preferred.

In the event of any liquidation or winding up of the Company, the holders of the
Series B Preferred  are  entitled to receive,  in  preference  to the holders of
Common  Stock but  subject  to the  rights of the  Series A  Preferred  Stock on
liquidation,  an amount equal to the original  purchase price per share ($1,000)
of the Series B Preferred plus accumulated but unpaid dividends.

On December 17, 1996, 10 shares of the Series B Preferred  Stock were  converted
into 12,804 shares of Common Stock.

At December  31,  1997,  the Company has net loss  operating  carryforwards  for
federal  and  state  income  tax  purposes  of  approximately   $16,100,000  and
$4,800,000,  respectively.  The Company also has research and development credit
carryforwards  for  federal  tax  purposes of  approximately  $145,000.  The net
operating loss and credit  carryforwards  expire in varying  amounts through the
year 2011.

Pursuant to the Tax Reform Act of 1986,  use of the Company's net operating loss
and research and development credit  carryforwards may be substantially  limited
if a  cumulative  change  in  ownership  of more  than  50% of the  value of the
Company's stock occurs within any three-year period.

6.  Common Stock

The Company closed a private  placement on March 29, 1996. Gross proceeds raised
were  $5,960,000.  In this  placement the Company issued units in lieu of single
shares of common stock.  Each unit consists of one share of common stock and one
common stock purchase  warrant ( the "units").  Each warrant entitles the holder
to purchase one-half of a share of common stock and is exercisable for ten years
from the date of original issuance of the warrants at the initial closing of the
private  placement  ( the  "original  issuance  date"),  subject to two  vesting
conditions  both of which have been met.  Two  warrants are required to purchase
one share. The units were offered to accredited  investors only and were offered
at $1.10 per unit ( the "unit offering  price").  There was no minimum  offering
amount.  The  warrants,  which were  issued as a  component  of the  units,  are
exercisable at the following prices:

         (i)  50% of the  total  number of  warrants  held by the  investor  are
              exercisable  because  within three years of the original  issuance
              date,  the Company  issued common stock or securities  convertible
              into common stock at a price below the unit  offering  price.  The
              exercise  price of such warrants  vested in 

                                      F-11

<PAGE>


              accordance  with  this  paragraph  (i) will be equal to the  price
              offered to the investors in the subsequent financing,  i.e., $0.25
              per share.

         (ii) 50% of the  total  number of  warrants  held by the  investor  are
              exercisable  because  within  two years of the  original  issuance
              date,  the  Company's  common  stock is not  quoted on the  NASDAQ
              SmallCap Market or the NASDAQ National Market.  The exercise price
              of such warrants  vested in accordance  with this  paragraph  (ii)
              will be equal to the unit offering price, i.e., $1.10 per share.

The  shareholders  have since amended an  additional  condition of the placement
which restricted the Company,  for three years from the original  issuance date,
from any grant of stock  options under its existing or future stock option plans
at an exercise price less than 110% of the Unit Offering  price. At the June 26,
1996 Annual Meeting of Shareholders, proposals to replace or amend the Company's
two option plans were  presented for vote of the  shareholders.  Both  proposals
specified  the  number  of shares  reserved  for  issuance,  the types of grants
allowed, the eligibility, and the terms of the options including exercise price,
term and termination of options. Both proposals were approved by over 51% of the
shares  eligible to vote at the meeting and by over 71% of those shares actually
voted.

The Company has reserved  652,299  shares of Common Stock for the  conversion of
the Series A  Preferred  Stock,  and  1,476,313  shares of Common  Stock for the
conversion of the Series B Preferred Stock.

In connection with the private  placement  issuance of Common Stock in 1995, the
Company issued for services rendered warrants to acquire 64,184 shares of Common
Stock at $0.898 per share. The warrants are fully exercisable and expire June 8,
1998. In connection with the private placement  issuance of Common Stock in 1995
and 1996, the Company issued for services  rendered  warrants to acquire 225,765
shares of Common Stock at $1.32 per share.  The  warrants are fully  exercisable
and expire March 26, 2001. In connection  with a private  placement  issuance of
Common  Stock in 1997 , the Company  issued for  services  rendered  warrants to
acquire  218,500  shares of Common  Stock at $0.25 per share.  The  warrants are
fully exercisable  and  expire  March  26,  2002. In  connection  with a private
placement  issuance of Common  Stock in 1997,  the Company  issued for  services
rendered warrants to acquire 320,000 shares of Common Stock at $0.375 per share.
The warrants are fully exercisable and expire November 13, 2002.

Common shares issued for services have been recorded at amounts that approximate
the fair value of the shares at time of issuance.

During 1989, 1991,  1993, and 1995, the Company reserved 30,000 shares,  100,000
shares,  150,000 shares, and 200,000 shares,  respectively,  of Common Stock for
issuance  to certain  non-employee  directors  under the 1989 and 1991  Director
Incentive Stock Plan (Director  Plan).  Directors must meet certain  eligibility
requirements  for stock  awards under the  Director  Plan.  All stock awards are
fully vested at the time of grant and are for services  rendered to the Company.
The number of shares  issued is  calculated  upon a fixed dollar  amount and the
share price at the date of record.

During 1995 the Company reserved a total of 200,000  additional shares of Common
Stock under the 1991 Director  Stock Plan.  The Company  issued  165,714  shares
under the  Director  Plan  during  1997 (1996 -- 72,138  shares,  1995  --89,965
shares).

In 1993,  the Company had  reserved a total of 50,000  shares of Common Stock to
issue under the Advisory  Board Stock  Program.  The terms of the Advisory Board
Stock Program are similar to those of the 1991  Director  Stock Plan except that
advisory  board  members are awarded  1,000  shares per  meeting  attended.  The
Company  issued no shares of Common Stock under the Advisory Board Stock Program
in 1997 (1996 -- issued 3,000  shares at $1.03 per share,  1995 -- issued 4, 000
at $0.88 per share).

Under  several  stock  option  plans,  the Company  has  granted  options to key
employees,  consultants, and directors to acquire shares of the Company's Common
Stock at prices  that are  generally  equal to fair  value at the date of grant.
Employees and  consultants  options  generally vest over five years (three years
for grants prior to January 1, 1991)

6. Common Stock (continued)

and expire if not  exercised  within ten years of the date of grant.  On June 7,
1996 the  Company's  shareholders  approved the 1996 Stock Plan.  Under the plan
1,500,000  shares of Common Stock were  reserved for issuance  upon  exercise of
options  granted  under the 1996 plan in  addition  to the shares  which  remain
available for issuance under the 1986 plan.  Effective with the approval  of the
1996 Plan, the entire reserve of shares for grants of future options pursuant to
the 1986  Plan  were  canceled.  The 1986 Plan  expired  by its terms  effective
February,  1997. Such  termination will not affect the shares subject to options
currently  outstanding  under the 1986 Plan.  At December 31,  1997,  there were
1,373,186  options issued and outstanding  under the various plans and 1,331,948
available for issuance.

The  Director  Option Plan  provides for the granting of options to directors to
acquire  shares of the  Company's  Common Stock at prices equal to fair value at
the date of grant.  These options are fully exercisable upon grant and expire if
not  exercised  within ten years  from the date of grant.  The  Company  granted
options to acquire 60,000 stock shares of Common Stock under the Director Option
Plan in 1997 at $0.47 per share ( in 1996  granted  70,000  options at $1.85 per
share, and in 1995 granted 70,000 options at $1.16 per share).

<TABLE>
The exercise price of each option generally approximates the market price of the
Company's stock on the date of grant. Accordingly, no compensation cost has been
recognized  for the plan.  Had  compensation  cost for the plan been  determined
based on the fair value of the  options at the grant dates  consistent  with the
method of  Statement of  Financial  Accounting  Standards  123,  Accounting  for
Stock-Based Compensation ("SFAS 123"), the Company's net loss and loss per share
would have been reduced to the pro forma amounts indicated below.

7.  Development and marketing agreement

Starting in 1990, the Company received from The Boeing Company ("Boeing") over a
three year period,  $3.7 million for equipment and the  construction  of a clean
room laboratory.  In connection with the expiration of the agreement with Boeing
in 1994,  Boeing agreed to allow the Company continued use of these assets at no
cost. In September 1997, Boeing transferred these assets to the Company with the
proviso that the Company  assumes all costs and  liabilities  for disposition of
the assets upon  completion  of the  Company's  continuing  need for the assets.
Accordingly, the Company has no basis in the assets transferred from Boeing, and
accordingly  does  not  reflect  them in the  accompanying  balance  sheets.  In
connection  with the  construction  of the clean room  laboratory,  the  Company
entered into an agreement to rent office and  manufacturing  space in a building
owned by Boeing.  The original  lease expired in February  1997. A revised lease
was  negotiated  with one year  fixed  and a month to month 

                                      F-14
<PAGE>

arrangement  for an additional 24 months at varying cost per month.  The Company
agreed  that upon  notice  Boeing  could  occupy up to 9,000  square feet of the
building with per month costs adjusted accordingly.

      12 months fixed to January 31, 1998              $22,500 per month
      09 months month to month to October 31, 1998     $22,500 per month
      03 months month to month to January 31, 1999     $27,500 per month
      03 months month to month to April 30, 1999       $32,500 per month
      03 months month to month to July 31, 1999        $37,500 per month
      03 months month to month to October 31, 1999     $42,500 per month
      03 months month to month to January 31, 2000     $45,000 per month


8.  Operating leases

The Company has entered into operating leases for facilities and equipment.  The
future minimum payments under these leases are as follows:


          1998                               $   287,905

10. Related party transactions

LandRay Technology,  Inc. is a Delaware corporation  incorporated in 1996. Power
Spectra was a founding  stockholder in LandRay.  Power  Spectra's  investment in
LandRay  consisted  of the  grant  of  license  to use  Power  Spectra's  ground
penetrating radar technology in the area of mineral and fossil fuels exploration
and exploitation.  Power Spectra has not invested any cash in LandRay. In return
for the  license,  Power  Spectra  received  50% of the  initial  stock  issued.
Subsequent  financing by LandRay has reduced Power  Spectra's  ownership to 31%,
and  this  ownership  interest  will be  further  diluted  as Land  Ray  obtains
additional  equity.  It is  anticipated  that  Land  Ray  will  need to raise an
additional $2.5 million in 1998 in order to meet its contractual  obligations to
the company,  assuming the company is successful in meeting contract milestones.
On a contractual basis,  Power Spectra develops and manufactures  systems unique
to LandRay's  licensed area of operations.  Power Spectra  retains all rights in
intellectual property developed for any LandRay oriented product.

The only affiliate of the Company with an ownership  stake in LandRay is Gene J.
Kennedy,  a  director  of the  Company,  who  owned  approximately  1.2%  of the
outstanding  shares of  LandRay at  December  31,  1997.  Power  Spectra  has no
significant  role in the management  and operations of LandRay.  Ridge Harlan is
LandRay's  Chairman  of the  Board  and  Kenneth  Smith is its  Chief  Executive
Officer.  LandRay  currently  has two  full  time  employees,  three  part  time
employees, and is recruiting others.

The Company  recognized  revenues of $550,000  upon  completion  of  contractual
milestones  under the initial June 19, 1996 contract with LandRay's  organizers,
European Industries Associates,  and the Company recognized revenues of $750,000
for the year ended December 31, 1997, upon completion of contractual  milestones
delineated  in the contract  dated  December  17, 1996,  as amended on March 13,
1997. To complete this contract, the Company must meet two additional milestones
with a total value of $450,000.

                             AMENDMENT NUMBER 12 TO
                       RESEARCH AGREEMENT 9-1110-JET-103

This AMENDMENT,  designated as AMENDMENT Number 12, effective as of 17 September
1997, is entered by and between POWER SPECTRA,  INC., having a place of business
in  Sunnyvale,  California  (hereinafter  referred  to as "PSI")  and THE BOEING
COMPANY,  (including its subsidiaries and affiliates) acting through its Defense
& Space Group,  having a place of business at Seattle,  Washington  (hereinafter
referred to as "BOEING").

WHEREAS,  the  parties  have  previously  entered  into  that  certain  Research
Agreement  9-1110-JET-103 dated September 21, 1989, and Amendments 1-11 thereto;
and

WHEREAS,  since 1990,  PSI has used on its  premises  certain  capital and other
equipment owned by Boeing, all such equipment being now identified in Attachment
A hereto; and

WHEREAS,  PSI is currently leasing  commercial  facilities and office space from
ARGOSystems,  Inc.,  a  wholly  owned  subsidiary  of  Boeing,  pursuant  to the
ARGOSystems/PSI Lease Agreement dated 22 November 1991, as amended;

WHEREAS,  BOEING  wishes to  transfer to PSI,  the  capital and other  equipment
identified in Exhibit A, for no consideration  except as described  herein,  and
PSI wishes to accept such capital and other  equipment under the terms described
herein;

NOW, THEREFORE, the parties hereto agree as follows:

1.   Notwithstanding  any other provision of Research Agreement  9-1110-JET-103,
as amended,  effective  on the date of this  Amendment,  BOEING  transfers  full
title,  conveys,  and gives to PSI, for the consideration  described herein, the
capital and the other equipment described in Attachment A.

2.   PSI is  accepting  this  equipment  for use and not for scrap or  disposal.
Nonetheless,  PSI assumes all responsibility to dispose of any capital and other
equipment of  Attachment A which it may not wish to retain,  such disposal to be
fully compliant with all federal, state, local, and community laws, regulations,
and  requirements,  at no  cost  or  expense  to  BOEING  or  ARGOSystems.  Upon
termination of the ARGOSystems/PSI  lease agreement dated 22 November 1991, PSI,
as owner of the capital and other equipment in Attachment A, shall remove it all
completely  from the leased  premises,  restoring  such premises to its original
condition  (with  allowance for reasonable wear and tear), at no cost or expense
to BOEING or to ARGOSystems.

3.   DISCLAIMER.  PSI accepts this  equipment  "AS IS" and without any warranty.
PSI HEREBY WAIVES ALL OTHER WARRANTIES,  GUARANTEES,  OBLIGATIONS,  LIABILITIES,
RIGHTS AND REMEDIES, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE,  INCLUDING
BUT NOT LIMITED TO THE IMPLIED WARRANTY OF MERCHANTABILITY, ANY IMPLIED WARRANTY
ARISING  FROM COURSE OF  PERFORMANCE,  COURSE OF DEALING OR USAGE OR TRADE,  ANY
IMPLIED  WARRANTY OF FITNESS,  AND ANY  OBLIGATION  OR LIABILITY OF BOEING,  ITS
SUBSIDIARIES,  AFFILIATES  (AND  RESPECTIVE  DIRECTORS,  OFFICERS AND EMPLOYEES)
ARISING FROM TORT, OR FOR LOSS OF USE,  REVENUE OR PROFIT,  OR FOR INCIDENTAL OR
CONSEQUENTIAL DAMAGES.

4.   SPECIAL TERMS REGARDING HAZARDOUS SUBSTANCES AND/OR RADIOACTIVE  MATERIALS.
The  capital  and  other  equipment  may  contain  hazardous  substances  and/or
radioactive  materials which,  upon the end of the equipment's  useful life, may
require special handling for final disposition.

Release.  PSI has  satisfied  itself  regarding the condition of the capital and
other equipment covered by this Agreement.  Upon taking title of this equipment,
PSI hereby agrees to assume complete  responsibility  for handling,  management,
transport,  and use of the capital and other  equipment,  and if  undertaken  by
Power  Spectra,  the removal and  disposal of any  hazardous  substances  and/or
radioactive  materials therein or thereon,  in accordance with existing federal,
state  and  local  laws and  regulations.  Power  Spectra  further  assumes  all
responsibility to provide  appropriate  personal protective measures for itself,
its  employees,  agents and assigns,  as well as any third  parties  potentially
exposed  to any  hazardous  substances  and/or  radioactive  materials  from the
capital and other equipment.  PSI releases The Boeing Company, its subsidiaries,
affiliates and their respective directors,  officers, employees, agents from any
and all  liability  arising from or related to the hazardous  substances  and/or
radioactive  materials  now  contained in or on the capital and other  equipment
obtained hereunder.

Indemnity. PSI shall defend, indemnify and hold harmless The Boeing Company, its
subsidiaries,  affiliates and their respective directors,  officers,  employees,
agents (hereinafter  referred to as "Indemnitees") from and against all actions,
causes of action, liabilities,  claims, liens, suits, judgments,  awards, fines,
penalties,  and damages, of any kind and nature whatsoever brought or claimed by
Boeing or any other party and expenses and costs of litigation  and counsel fees
related  thereto,  or incident  to  establishing  the right to  indemnification,
arising out of or in any way connected with any cleanup, containment,  remedial,
removal or restoration work required or performed by any federal, state or local
governmental   agency   or   political   subdivision,   or   performed   by  any
non-governmental entity or person,  including The Boeing Company, because of the
presence or suspected  presence,  release or threatened or suspected  release of
hazardous substances and/or radioactive  materials in or into the environment at
on about under or within any property or any disposal site used by PSI, relating
to the capital  equipment and any claims of third parties for loss,  injury,  or
damage to persons or property arising from or related to any residual  hazardous
substances  and/or  radioactive  materials now contained in or on the capital or
other equipment obtained hereunder.

5.   All other  provisions  of the Research  Agreement of September 21, 1989, as
amended, shall remain unchanged.

IN WITNESS WHEREOF,  the authorized  representatives  of the parties hereto have
executed this Amendment No. 12 in duplicate originals.

                             AMENDMENT #2 TO LEASE
                     DATED NOVEMBER 22, 1991 BY AND BETWEEN

                  ARGOSystems, INC., A WHOLLY OWNED SUBSIDIARY
                        OF THE BOEING COMPANY, AS LESSOR

          AND POWER SPECTRA, INC. A CALIFORNIA CORPORATION, AS LESSEE

     THIS  AMENDMENT  #2 TO  LEASE,  entered  into and made as of the 9th day of
October, 1997, by and between  ARGOSystems, Inc. as Lessor,  and Power  Spectra,
Inc., a California corporation, as Lessee.


                                  WITNESSETH:

     WHEREAS,  Landlord and Tenant have heretofore entered into a certain lease,
dated  November  22,  1991,  as amended by  Amendment  No. 1 dated July 23, 1993
(collectively,  the "Lease"), of certain space at 919 Hermosa Court,  Sunnyvale,
CA, (the "Premises"), upon terms and conditions described in said Lease; and

     WHEREAS, Lessor and Lessee desire to amend said Lease as described below;

     NOW THEREFORE,  in  consideration of the rents reserved and of the covenant
and agreements  herein set forth,  it is agreed that the Lease be hereby amended
from and after the date hereof as follows:

     1. The Option Term set forth in Section 3.  "OPTION TO RENEW" of the Lease,
is reduced in  duration  from 2 years to 1 year  ("Revised  Option  Term").  The
Revised  Option Term is deemed to have  commenced as of the first day  following
the date upon which the original term ended,  or February 1, 1997, and shall end
on January 31, 1998.

     2. The  provisions of Section 3.,  paragraph b. of the Lease with regard to
the method for  setting  the basic  monthly  rental rate for the Option Term are
hereby amended to provide that the monthly basic rent payable during the Revised
Option  Term shall be fixed at $22,500  per month  ("Revised  Option  Term Basic
Rent"),  plus operating  expenses.

     3.  Lessor  shall  have an option,  exercisable  upon Sixty (60) days prior
written notice to Lessee, to occupy certain premises (the "Take-back  Premises")
constituting  a portion of the Premises as defined in Article 1.,  "PREMISES" of
the Lease. The Take-back Premises  approximate 9,000 square feet of the Premises
and are delineated on Exhibit "A", to this Amendment #2,  attached hereto and by
this reference made a part hereof.


<PAGE>


     4. In the event  that  Lessor  shall  exercise  its  option  to occupy  the
Take-back  Premises in accordance  with this Amendment #2, Lessee shall promptly
surrender  the  Take-back  Premises  to Lessor in  accordance  with the terms of
Article 27., "SURRENDER" of the Lease and with the provisions of Paragraph 5. of
this Amendment #2; except that,  solely with respect to the Take-back  Premises,
Lessee shall not be obligated to paint or clean interior  walls,  clean carpets,
service air conditioning and heating systems, or clean and wax floors within the
Take-back Premises.

     5.  a. Lessor and Lessee acknowledge that certain capital equipment located
on the Premises at the date of this Amendment #2 has been  transferred to Lessee
by the  Boeing  Corporation  pursuant  to a certain  agreement  entitled  "Draft
Amendment  Number  12  to  Research  Agreement   9-1110-JET-103"   (the  "Boeing
Amendment").  The capital equipment transferred pursuant to the Boeing Amendment
is listed on the  Attachment  thereto  ("Attachment  A").  A copy of the  Boeing
Amendment with Attachment A is  attached as Exhibit "B" to this Amendment #2 and
incorporated herein by this reference.

         b. Lessee agrees,  notwithstanding any other or different provisions in
the  Lease  proper  regarding  condition  of  the  Premises  upon  surrender  at
termination of Lessee's occupancy, that Lessee shall:

             (i)  remove  from  the  Take-back  Premises  all  items  listed  on
Attachment A to the Boeing Amendment within 30 days of receiving Lessor's notice
pursuant to Paragraph 3 of this Amendment #2; and

             (ii) remove from the Premises  all items listed on  Attachment A to
the Boeing  Amendment  promptly upon  termination  of Lessee's  occupancy of the
remainder of the Premises for any reason.

         c. with respect to the capital  equipment  set forth on Attachment A to
the Boeing  Amendment,  Lessee hereby assumes all cost and expense and all legal
responsibility  and liability  therefor,  whenever arising,  including,  without
limitation,  the payment of all costs and  expenses  of: (1) removal from all or
any portions of the Premises; and (2) prompt restoration of such portions of the
Premises to the condition they were in prior to the  installation  thereof;  and
(3) disposal or other disposition thereof after such removal.

         d. Lessee agrees to defend, indemnify and hold Lessor harmless from any
and all loss, damage, cost or expense directly or indirectly caused to Lessor as
a  result  of  Lessee's  failure  refusal  or  neglect  to  perform  in full the
obligations assumed

                                      -2-

<PAGE>


under subparagraph 5.(c), above.

     Lessor and Lessee agree that except as specifically stated in Paragraphs 4.
and 5. of this  Amendment #2,  nothing  herein shall be deemed to alter or amend
the  obligations  of  Lessee  under the terms of  Article  27 of the Lease  with
respect to the condition of the Premises at the time of Leasee's surrender.

     6. From and after the date of Lessor's  written  exercise of its option set
forth  herein,  Lessee  shall use its best efforts to  surrender  the  Take-back
Premises to Lessor  within  sixty (60) days of the  serving of Lessor's  notice.
Failure of Lessee to surrender the Take-back  Premises to Lessor within the time
provided  shall  entitle the Lessor to declare a default of the Lease,  to serve
Lessee with a Notice to Quit,  and,  unless  Lessee  shall cure such  default by
surrendering  the  Take-back  Premises  in  accordance  herewith  prior  to  the
institution of unlawful detainer or other legal proceedings,  to pursue, without
limitation,  all  remedies  set  forth in the Lease and  otherwise  provided  to
Lessors under the laws of California in cases of default.

     7. In the event that Lessee shall timely  surrender the Take-back  Premises
to Lessor in the condition  specified under paragraphs 4 and 5 of this Amendment
#2,  following  Lessor's  exercise  of its  option  as  set  forth  herein,  all
post-surrender  expenses  of  preparing  the  Take-back  Premises  for  Lessor's
occupancy  shall  be  borne by  Lessor.  Lessor's  obligation  for  expenses  of
occupying the Take-back  Premises shall not include  costs,  if any, of Leesee's
preparations for occupancy, upgrades,  alterations,  reconfigurations,  or other
improvements  ("Improvements") to any portion of the Premises remaining occupied
by  Lessee,  which  Lessee  may wish to  perform  in  connection  with  Lessee's
surrender of the Take-back Premises, regardless of whether caused, or claimed to
have been  caused,  by reason  of  Lessor's  exercise  of the  option.  All such
Improvements,  if any, to the Premises  which  Lessee  shall  continue to occupy
shall be at Leasee's sole cost and expense.

     8. Upon  Leasee's  surrender of the Take-back  Premises  after Lessor shall
have  exercised  its  option  set forth in  Paragraph  3 of this  Amendment  #2,
thereafter monthly  obligations for Revised Option Term Basic Rent and operating
expenses (and for Month-to-Month  Extended Term, if any, as hereinafter defined)
shall be apportioned on a dollar-for-dollar  basis between the Lessor and Lessee
according  to a ratio of 9  (Lessor's  share) to 16  (Leasee's  share)  ("Shared
Occupancy  Ratio").  For  example,  if  Revised  Option  Term  Basic  Rent for a
hypothetical  month were $22,500 and an ordinary operating building expense line
item were $4,200 for the same  hypothetical  month,  Leasee's share of such rent
payments for such month according to the Shared Occupancy Ratio would be $17,088
and Lessor's share of such rent payments for such month

                                      -3-

<PAGE>


according to the Shared Occupancy Ratio would be $9,612.  The parties  stipulate
that the foregoing Shared Occupancy Ratio is a fair and reasonable approximation
which the parties  have  agreed to in  consideration  of the mutual  agreements,
covenants,  conditions,  and undertakings of this Amendment #2 and of the Lease,
for other good and  valuable  consideration,  and after  negotiations  conducted
having regard for all the relevant commercial circumstances.  Accordingly,  each
party  waives  any  right,  claim,  or  action it may have or assert at any time
hereafter  to seek a  re-computation  of the  foregoing  ratio as the  basis for
apportioning  rent and operating  expenses after Lessee surrenders the Take-back
Premises to Lessor upon Lessor's exercise of its option as set forth herein.

     9. The  provisions  of  Section  3.,  paragraph  c. of the Lease are hereby
amended to provide that after  January 31, 1998,  the end of the Revised  Option
Term, the Lessee may continue to occupy the Premises (exclusive of the Take-back
Premises,  if Lessor  shall  have  exercised  the  option  provided  for in this
Amendment #2) on a month-to-month basis for a duration not to exceed twenty-four
(24) months  ("Month-to-month  Extended Term"). The Month-to-month Extended Term
may be terminated  prior to the end thereof by either party without cause  on 90
days' written  notice to the other.  Basic rent and operating  expenses shall be
payable monthly by the Lessee  (subject to sharing with Lessor  according to the
Shared  Occupancy  Ratio,  if  applicable)  prior  to  the  termination  of  the
Month-to-Month Extended Term. Basic rent during the Month-to-Month Extended Term
shall not exceed the  following  amounts  for the  following  indicated  periods
during the  Month-to-month  Extended Term:

                              Months 10, 11, 12:  $27,500.00
                              Months 13, 14, 15:  $32,500.00
                              Months 16, 17, 18:  $37,500.00
                              Months 19, 20, 21:  $42,500.00
                              Months 22, 23, 24:  $45,000.00

     (All such amounts are stated without  application  of the Shared  Occupancy
