ITEM 1.  BUSINESS

General

         Power Spectra,  Inc. ("Power Spectra" or the "Company") is a California
corporation  organized in 1979 and operates as a single business segment.  Prior
to 1990, the Company was a development stage company.

         The Company  develops,  designs,  manufactures  and markets a family of
products  that  utilize   proprietary   Gallium  Arsenide  ("GaAs")   high-speed
semiconductor   devices  which  are  capable  of  generating   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 are optically  triggered  high-power  switches which have applicability in
high-resolution  radar,  electronic  warfare,  communications,   and  industrial
applications such as level control, positioning,  velocity measurement, obstacle
detection and avoidance,  and many other industrial uses.  Historically BASS(TM)
development and applications have primarily addressed military  requirements and
have accounted for roughly 90% of the Company's  revenues.  The Company believes
its new family of powerful,  reliable, cost effective pulsed optical and impulse
generating  switches also have growing  applications in a number of existing and
emerging  industrial  markets such as  Ultra-Wideband  Ground  Penetrating Radar
("UWB GPR"),  distance  measurement  sensors and automotive  collision avoidance
systems.

Bulk Avalanche Semiconductor Switch (BASS)(TM)

         The degree to which extremely rapid, high-power  electromagnetic pulses
can  be  generated   has  been  a  limiting   factor  in  the   improvement   of
high-resolution  radar and electronic warfare systems.  Generation of very short
duration,  high peak power pulses is not possible with existing  devices such as
krytrons, spark gaps, thyratrons, planar triodes, and avalanche transistors. All
these devices are limited by fundamental physics in turn-on time. It is also not
possible  to  generate  the high  peak  power,  very  short  duration,  time and
frequency  domain  coherent RF pulses  with other  devices  such as  magnetrons,
klystrons, or gyrotrons.

         The BASS(TM)  device has been  developed and patented by Power Spectra.
The creation of BASS(TM) technology has resulted from two important factors: the
evolution of gallium  arsenide  (GaAs)  technology for high-speed  semiconductor
applications,  and the  patented  Bulk  Avalanche  process,  developed  by Power
Spectra founder Stephen Davis.

         Gallium arsenide technology has well-established advantages for certain
semiconductor applications.  GaAs allows significantly faster electron travel in
semiconductors  and is much more  resistant to radiation  bombardment,  a factor
that is important in military and space applications.

         The BASS(TM) is a solid-state  gallium arsenide device roughly the size
of a  conventional  power  transistor  and  is  triggered  by a  small  external
semiconductor  laser diode. In its "off" state,  very high impedance is achieved
by the 

                                       3
<PAGE>

high-purity  GaAs.  Switching is achieved  when  electrons and holes are rapidly
accelerated  within the field of the device. By this means, the BASS(TM) changes
from a  non-conducting  to a conducting state in approximately 20 trillionths of
one second.  Because conduction is enabled and controlled  throughout the volume
of the BASS(TM), extremely high voltages can be controlled,  presently in excess
of 15 kilovolts. In addition, because of the uniform turn-on throughout the bulk
of the BASS(TM),  very rapid turn-on,  high voltage,  high current pulses can be
generated. The Company believes that the BASS(TM) could in the future enable the
development  of high  resolution  imaging  radar,  a new  system  of  electronic
warfare, and other applications.

Boeing Program

         Effective  January  1,  1989,  Power  Spectra  and The  Boeing  Company
("Boeing")  entered into a development and marketing  agreement  relative to the
Company's BASS(TM) products (the "Boeing Agreement").  Funding under the initial
2-1/2-year development term of that agreement was based on the Company's ability
to meet certain milestones in the development of the BASS(TM) technology and the
demonstration of manufacturable BASS(TM) devices.

         The initial phase of the Boeing Agreement was completed in 2-1/4 years.
A new agreement,  which continued through June 30, 1994, was negotiated pursuant
to which Boeing funded development costs of $4,200,000 in 1991 and $3,500,000 in
1992.  In  1991  and  1992,   the  Company   completed   significant   technical
demonstrations  of  capability  with Boeing in the areas of wide-band  radar and
electronic warfare.

         In March 1993, the Company  announced that Boeing would fund $3,100,000
for research  activities which were performed  entirely in 1993, and that Boeing
would fund  $1,600,000 for activities to be completed in 1994. In February 1994,
Boeing and Power Spectra  finalized the 1994  statement of work and extended the
research  agreement to August 31, 1994.  All work under the Boeing  statement of
work was completed and no additional funding is being provided by Boeing.

         The Boeing research period of performance  expired in June 1994.  Under
the terms of the amended  agreement,  Boeing  continues  to  provide,  on a loan
basis,  $2.8 million of equipment and has agreed to allow the Company  continued
rent-free  use of this  equipment,  subject  to annual  review.  If the  Company
desires to acquire title and ownership to the equipment,  the Company and Boeing
will negotiate appropriate consideration in return for such title and ownership.

         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 agreement,  and
to market systems containing BASS(TM) devices. In addition, the Company will pay
Boeing a royalty  of 4% of  BASS(TM)  product  sales up to a maximum  cumulative
royalty  payment of $10 million.  The Company  retains the right to  manufacture
BASS(TM) devices for incorporation into larger systems to be marketed by Boeing.

Air Force Contract

         In 1990,  the  Company  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 is being
used by the Air Force to test the effects of high power microwave pulses.

         The  Phase  I   cost-plus-fixed-fee   contract  value  was  $5,192,744,
including  $957,688  awarded in 1992  pursuant  to an  amendment  to Phase I. In
January 1993,  the Air Force  exercised an option (Phase II) to have the Company
manufacture  a  nine-element  antenna  array  for  a  total  contract  price  of
$3,537,510 over an 18-month period. An additional  modification relating to site
support and training was added in June 1993,  bringing the total  contract value
to  $8,739,290.  The  Company  delivered  the  nine-element  array in  mid-1994.
Subsequent to this delivery,  the Air Force has extended the contract to upgrade
the prototype  equipment  delivered in Phase I to a technology  level similar to
that provided in Phase II. This contract extension raised the aggregate contract
value to $9,533,771. In 1995, the US Army contracted through the Air Force using
the Air Force's  existing  contract  with the Company to deliver a Phase II-type
technology  transmitter for use in foliage and ground penetrating radar testing,
and perform a risk reduction  assessment to make the technology suitable for use
onboard aircraft.  The aggregate  contract value was increased to

                                       4
<PAGE>

$10,517,881 on February 8, 1995. The Company 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 still  subject to 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 both  routine  and  required,  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.

Commercial Products

         As part of the Company's  diversification  effort in 1992,  the Company
entered  into a  technology  license and  development  agreement  with the Ioffe
(pronounced "yahf-ah")  Physical-Technical  Institute ("Ioffe"), St. Petersburg,
Russia (the  "Ioffe  Agreement").  Ioffe and the Company are jointly  developing
advanced gallium arsenide  semiconductor  devices. To accelerate the development
of such  devices,  Russian  scientists,  sponsored in part by the United  States
Depar(TM)ent of Commerce Special American Business  Internship  Training (SABIT)
Program,  were brought to work at the Company's  Sunnyvale  facility for varying
periods to facilitate the technology transfer.

         Development  of a new line of  semiconductor  products,  using advanced
gallium  arsenide  switching  technology to enhance the  Company's  laser driver
technology,  was  launched.   Initially  undertaken  to  support  the  Company's
BASS(TM)-based  systems,  the  Company  believes  that such a  product  line has
broader  applications,  and the  Company's  goals for this  product line are now
focused  on mass  industrial  and  military  markets  not  associated  with  the
BASS(TM).

         In 1996 the Company changed the main focus of its business efforts from
the military  market to the  commercial  sector.  The Company has identified and
begun the  development  of the initial  products and services for three separate
commercial  applications,  each with significant market and profit potential for
the Company.* These initiatives are: 1) a joint venture for the development of a
commercial  GPR-based  mineral  and  petroleum  exploration  system;  2) a joint
venture for the development of a helicopter-mounted  GPR system for the location
and identification of buried artifacts;  and 3) the development and marketing of
an electro-optical range finder for the industrial marketplace.

         Several other products have been developed for the industrial  markets.
The Company  introduced two such products during late 1993 and an additional two
products in the first quarter of 1994.  Promotion of these products has included
news  releases,   advertising  in  trade  publications,   direct  mailings,  and
exhibition at trade conferences.

         The first product, called the BASS-01X, is a compact,  high-peak power,
ultra-wideband pulse generator based on the Company's BASS(TM) technology.  This
unit  generates  a  0.5-megawatt,  600-picosecond  video  pulse  waveform.  This
waveform has a fast leading edge of less than 120 picoseconds, which provides an
ultra-wideband  frequency spectrum extending from D.C. to in excess of 3GHz. The
unit is  meant  to  serve  as a  reasonably  priced  demonstrator  that  permits
customers to explore  high-power  ultra-wideband  pulse  technology in their own
applications.  The Company believes, as was exemplified by the sale of the first
unit,  that small size and ruggedness will enable the BASS-01X to be used in the
field for such commercial  objectives as underground  site surveying,  since its
high peak power makes it useful for airborne and deep ground penetration units.*

         The second product,  called the Pulsed Optical Source  (POS(TM)),  is a
device that integrated a pulsed laser diode and GaAs driver  circuitry  directly
within a  windowed  TO-5 can  measuring  0.33  inches in  diameter.  Performance
features are high peak power and  5-nanosecond  pulses at pulse repetition rates
up to 20  KHz.  Potential  applications  include  laser  rangefinders,  position
sensors, motion sensors, and communications. Sales to date for such applications
have been for small  quantities,  typically for  evaluation  and  integration in
larger  systems,  and the Company  knows of one large  system  design  which has
incorporated a prototype into the product.

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"  for a discussion of
factors that could affect future performance.

                                       5
<PAGE>

         The PGS-401,  a 2.5 KW impulse  transmitter,  was  introduced  early in
1994.  At the end of the year,  a lower cost,  lower  performance  version,  the
PGS-402, was introduced.  Subsequently,  the PGS-403,  PGS-404, and PGS-405 have
been  introduced.  The PGS-401 and PGS-402 are no longer  offered for sale.  The
Company believes that these products have  applications  for ground  penetrating
radar, test instrumentation, electronic warfare, and communications.*

         In mid-1995, the Company introduced an industrial laser-ranging product
based on the Pulsed  Optical  Source  (POS(TM)) to address  existing  industrial
markets. Although the initial prototype experienced difficulty in its ability to
calculate  range  accurately,  a new design is presently  being tested and shows
promise of lower manufacturing costs.

         Several variants of the BASS-01X were produced and sold during 1995 and
1996.  The BASS-02X and BASS-03X  produce  waveforms and power levels  different
from the basic BASS-01X.  These were developed to match specific customer needs.
All of the BASS-0XX  series are packaged in a common,  81-cubic inch,  six-pound
package.

         To date, the Company has not generated  significant revenues from sales
of  commercial   products.   There  can  be  no  assurance  that  any  of  these
aforementioned  commercial  will be accepted in their target  markets,  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.

Manufacturing

         The  Company  manufactures  all  of  its  products  at  its  Sunnyvale,
California  manufacturing  facility. In 1991, the Company completed construction
and put into operation a modern semiconductor  fabrication facility for BASS(TM)
development.  Boeing  provided  the funds to complete  the  construction  of the
facility and owns the facility and most of the equipment. This facility was used
as a prototype facility to identify the manufacturing requirements for BASS(TM).
The  facility  and  equipment  are  suitable  for  moderate  volume   pilot-line
production of devices to meet current application requirements.  This capability
has facilitated significant  improvements in product performance and reliability
as well as  productivity  of the staff.  During 1994,  the Company  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 out-sourcing.
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.

         Boeing has  granted the  Company  the right to use its  equipment  on a
loaned  basis  for  the   Company's   purposes,   subject  to  annual   renewal.
Additionally,  should the Company  desire to acquire  title and ownership of the
loaned equipment,  Boeing and the Company will attempt to negotiate  appropriate
consideration in return for the transfer of title and ownership.  However, there
is no assurance that an agreement  satisfactory to the Company could be reached.
If Boeing  chooses to no longer loan the equipment to the Company,  as it may do
in its sole discretion,  and an acceptable  agreement for the Company's purchase
of the  equipment  cannot be  attained,  the  Company  would be required to find
alternative sources of equipment,  either for purchase or rent, or would have to
outsource  its  manufacturing  while  still  in  possession  of a  manufacturing
facility.  Any of these  circumstances 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.

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

Sales, Marketing, and Distribution

         Until the beginning of 1996,  the Company was primarily  focused on the
military  marketplace  and its  applications  for the Company's  technology.  In
January 1996,  the Company  changed the main focus of its business  efforts from
the military  market to the  commercial  sector.  The Company has identified and
begun  the  development  of  the  initial  products  and  services  for  several
commercial applications.

         The Company seeks a balance  between  industrial or standard  products,
and the major research and  development  efforts that have sustained the Company
in the past. In the military  sector,  the Company believes that the markets for
systems in which the Company's  BASS(TM) and  PSIristor(TM)  technologies  could
play a major role may  experience  less drastic  cutbacks  than weapons  systems
suitable  only for  strategic  warfare.*  The Company  also  believes  that U.S.
Government  spending  is  being  increasingly   directed  towards  research  and
development of innovative technologies such as the BASS(TM) and PSIristoro(TM).*
Also,   advanced  radar  and  electronic   warfare  systems  were  shown  to  be
particularly  effective  in  "Desert  Storm."  The  military,  has in the  past,
publicly stated that technology may allow leveraging strike force  effectiveness
in regional  conflicts,  and  protection  for forces from  battlefield  hazards.
Currently,  mine detection  capabilities  are being evaluated and debated by the
military and in the national press.

         The  marketing  goals  of  the  Company  include   obtaining   advanced
development contracts for new hardware based on equipment successfully delivered
to  military  customers  while  continuing  to expand its  industrial/commercial
product  line.  The Company  believes  that,  its  products  improved in several
respects during 1996 through miniaturization and increased reliability resulting
from  ongoing   developmental   work.  The  Company  believes  that  the  unique
characteristics of the BASS(TM) and PSIristoro(TM)  make the products attractive
for a variety of potential new applications.*

         The Company's  marketing  activities for its gallium arsenide  products
are conducted by an internal marketing staff. The Company's marketing activities
include  advertising in selected trade  publications and  participation in trade
shows, symposia, and conferences.

Competition

         The  capabilities of the BASS(TM) device have attracted other companies
with light-activated  semiconductor  technologies to compete in this market. The
major  competitive  technology in this area is the  linear-mode  light-activated
switch.  This device does not utilize  the unique  avalanche  phenomenon  of the
BASS(TM) and, therefore,  requires a large laser for its operation.  The Company
believes that system  end-users may not consider these systems  attractive since
the large  lasers are  generally  unreliable,  inefficient,  and do not have the
pulse repetition capability needed for some applications.*

         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  resources than the Company.  The largest  competitors include Hughes,
Raytheon, Lockheed Martin, TRW, Tracor, and Northrop Grumman.

Pulsed Optical Source

         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 end.

- -----------------
*This statement is a forward-looking  statement reflecting current expectations.
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"  for a discussion of
factors that could affect future performance.

                                       7
<PAGE>

         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.  In  addition,  future
competition  is expected to develop  from EG&G,  Inc.  However,  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.

Pulse Generator Source

         In  order to  compete  for  other  niche  markets,  Power  Spectra  has
developed a family of  PSIristor(TM)-based  impulse  transmitters  that send out
high-power,  ultra-wide bandwidth signals through an antenna. These products are
available for sale to system vendors for use in a number of potential industrial
and environmental applications such as geographical exploration,  mine clearing,
pipeline mapping and leak detection, environmental cleanup, pavement assessment,
and airport ground surveillance.

         Failure  to  adequately  compete  in the  future  would have a material
adverse affect on the Company's business and results of operation.

Patents and Proprietary Rights

         The Company  relies  primarily  on its  technological  and  engineering
capabilities  for the development of its business.  The Company does not believe
that the grant of patents for concepts and processes  developed by its employees
is a critical  element of its future  growth.  However,  the  Company  does file
patent applications for certain concepts and processes. 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 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.

         The Company,  with the  assistance of Boeing,  has attempted to protect
its rights to the BASS(TM)  technology  by acquiring  licenses to other  patents
which could be relevant to the BASS(TM)  technology.  These license  rights,  as
provided  in  the  Boeing  Agreement,  belong  to  the  Company.  The  Company's
agreements  with the U.S.  Government  provide that the  Company's  research and
development   activities  entitle  the  government  to  limited  rights  to  the
applications  developed by the Company in the  performance of  government-funded
contracts.  However,  the government  does not obtain any rights to the BASS(TM)
technology itself.

         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 from the  unauthorized  disclosure and use of technology to which it
has rights,  and to provide 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 

                                       8
<PAGE>

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.

Backlog

         As of December 31, 1996,  the Company's  backlog was  $113,606,  versus
$801,261 at December 31, 1995,  and $1,261,338 at December 31, 1994. The Company
expects to complete all of its current backlog within the next twelve months.*

         Sales of the Company's  products are 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 meaningful indicator of future sales.

Government Contract Matters

         Historically, a material portion of the Company's business results 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.

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.  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.

Research and Development

         For the fiscal years ending  December 31,  1996,  1995,  and 1994,  the
Company's  research  and  development  expenses  were  $714,368,  $213,667,  and
$332,612,  respectively.  See  "Management  Discussion and Analysis of Financial
Condition and Results of Operations," for further discussion of this topic.

Employees

         As of December 31, 1996, the Company had 20 full-time  employees,  with
14 in technical  positions  and six in  administrative  capacities.  None of the
Company's  employees are 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.

 ITEM 2. PROPERTIES

         In late February 1992, the Company moved its headquarters from Fremont,
California,  to Sunnyvale,  California,  to combine all operations at a new site
where the Company's semiconductor processing facility was installed. The Company
leased 25,000 square feet of space 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. The Company is currently  negotiating renewal option
terms.  Payments under the lease total  $250,413 in 1996.  The Company  believes
that its current site is sufficient to house the  Company's  operations  for the
next twelve months.

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

         This  section and other parts of this  Report  contain  forward-looking
statements that involve risks and  uncertainties.  The Company's  actual results
may differ  significantly  from the  results  discussed  in the  forward-looking
statements.  Factors  that might cause such a  difference  include,  but are not
limited to, those discussed in the section entitled "Management's Discussion and
Analysis of Financial  Condition and Results of Operations -- Factors  Affecting
Operating  Results and Market  Price of Stock"  commencing  on page 15.  Certain
sections in this report  have been  identified  as  containing  forward  looking
statements.  The reader is cautioned that other sections and other sentences not
so identified may also contain forward looking information.

Results of Operations


         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  

                                       12
<PAGE>

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 Technologies 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  Technologies  joint venture,  and, as a result,  although operating
expenses have been reduced,  the Company's results of operations,  and financial
condition have been materially 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  an
decrease  of  $120,335,  or 24%,  compared  to sales and  marketing  expenses of
$494,804  in  1995.  Due  to  reduced  emphasis  government  contract  revenues,
personnel costs  associated  with such marketing  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  short  term  investment  of cash  reserves  which  increased  due to
completion of a private placement of Common Stock in March 1996.

         1996 was a period of continued  transition for the Company, as it moved
from research and  development  of laboratory  hardware to  application-specific
design and testing.  The Company continues contacts with a number of contractors
as well as Army, Air Force and Navy research  laboratories  regarding  potential
R&D  contracts.  One such  application  envisions  a  BASS(TM)  product  that is
appropriately  designed  and  packaged to  penetrate  foliage or earth.  An Army
Research  Laboratory  foliage  penetration  (FOPEN)  extension  to the Air Force
Contract for $984,000 was completed and expired on June 1, 1996.  The expiration
of this contract will have a material  adverse impact on future  revenues unless
other contracts are signed.

         1995 Compared to 1994

         Revenues for the year ended  December 31, 1995 were  $1,429,625,  which
were  $1,630,473  less than  revenues  of  $3,060,098  for the prior  year.  The
decrease  in the  Company's  revenues  in  1995  compared  to  1994  was  due to
expiration  of the  agreement  with The Boeing  Company on June 30, 1994,  which
provided $1,600,000 of revenue in 1994, and no additional revenue in 1995.

         The  Company  recognized  revenues  of  $814,285  under  the Air  Force
Contract in 1995,  versus  $1,233,829  for the  contract in 1994.  This  revenue
accounted for 57% of the Company's revenue in 1995 and 40% in 1994. During 1995,
the Company was unable to add  significant new contract  revenues and,  although
operating  expenses  have been  reduced,  the  Company's  revenues,  results  of
operations, and financial condition have been materially adversely affected.

         The net loss for the  year  ended  December  31,  1995 was  $2,562,230,
compared to a net loss of $1,112,507 in 1994.  After adjustment for dividends on
Preferred Stock of $189,195, the net loss applicable to common shares was

                                       13
<PAGE>

$2,751,425  or $0.25 per share as  compared  with a net loss for the year  ended
December 31, 1994 of $1,216,907 or $0.12 per share.

         Sales and marketing  expenses were  $494,804 in 1995,  representing  an
increase  of $64,693 or 15% over sales and  marketing  expenses  of  $430,111 in
1994. Due to reduced Boeing and Air Force revenues, marketing and advertising of
the Company's product  diversification efforts continued to expand in 1995 in an
attempt to obtain new military  contracts  and to sell  industrial  and standard
products.

         Research  and  development  costs  decreased  by  $118,945  in  1995 to
$213,667  from $332,612 in 1994, a 36%  decrease,  primarily  because of reduced
technical  costs due to the  completion of the transfer of the gallium  arsenide
semiconductor technology from the Ioffe Physical-Technical  Institute during the
year. Spending continued on new product development.

         General and administrative  expenses increased 9% or $85,048 in 1995 to
$1,062,589 from $977,541 in 1994, due primarily to increased personnel costs.

         The Company had no interest expense in 1996 compared to $18,126 in 1995
which arose from short-term financing.

         1995 continued the transition period for the Company,  as it moved from
research and development of laboratory hardware to  application-specific  design
and testing. The Company continues contacts with a number of contractors as well
as Army,  Air Force  and Navy  research  laboratories  regarding  potential  R&D
contracts.   One  such   application   envisions  a  BASS(TM)  product  that  is
appropriately  designed  and  packaged to  penetrate  foliage or earth.  An Army
Research Laboratory foliage penetration (FOPEN) contract for $984,000 was signed
February 8, 1995,  and expired on June 1, 1996.  The expiration of this contract
will have a material  adverse impact on future  revenues  unless other contracts
are signed.

         Liquidity and Capital Resources

         Working  capital at December  31,  1996 was  $212,998,  representing  a
decrease of $1,753,738  from  $1,966,736 at December 31, 1995. This decrease was
due primarily to net  operating  loss  $3,879,659  offset by the net proceeds of
$2,008,007  from the sale of Common  Stock in the first  quarter of 1996 and the
interest income generated from cash reserves.

         The Company  completed an offering of its Common Stock with proceeds to
the Company of $2,266,050 between January 1, 1996 and March 31, 1996.

         The Company's  growth  strategy  includes the successful  completion of
products  under  development,  development  of  new  product  applications,  and
development of 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 if completed,  or that the terms of any
such financing or partnership would be favorable to the Company.

         Accounts  receivable  at December  31, 1996  declined by $221,531  over
year-end 1995, while unbilled accounts decreased by $19,176 over the same period
for a net  decrease of $240,707.  The large net decrease in accounts  receivable
reflects both decreases in sales of standard  products and decreases in contract
development  activity  during the last fiscal quarter of 1996, and the fact that
the  LandRay  Technologies  Phase I  development  effort was prepaid in the late
third quarter and early fourth quarter 1996.

         Inventories   increased  by  $92,926  over  1995  year-end  levels  due
primarily to completion  of  sub-assemblies  for the  Company's  electro-optical
product line.

         Accounts  payable  decreased by $41,455 over 1995 year-end  levels as a
result the timing of vendor  payments  related to the Company's  annual  holiday
plant closure.

         Deferred  contract   revenues   increased  by  $121,857  from  customer
payments.

         The Company's  current cash position,  together with  anticipated  cash
flows from  operations  and new financing  through the issuance of Common Stock,
are expected by management to be sufficient to finance the Company's  operations
through  December  31,  1997.*  However,  the  actual  amount  of time  that the
Company's cash  resources last is dependent upon a variety of factors  including
the timing of obtaining new contracts, the timing of new financings, the success
of its current joint ventures and the  competition  with other  vendors.  If the
Company determines that it requires additional funds prior to December 31, 1997,
there can be no assurance that additional funds will be obtainable on reasonable
terms,  or at all. Any such failure could result in the Company  becoming unable
to meet its  obligations  as they come due. If the Company is not  successful in
replacing  the revenue and cash  generated by the Boeing  Agreement  and the Air
Force Contract,  the Company would continue to experience  significant operating
losses. The Company does not presently have access to any credit facilities.

         Subsequent  to  year  end,  the  Company  entered  into a $1.2  million
contract with LandRay Technologies,  Inc. ("LandRay"), a joint venture partially
owned  by the  Company,  as the  first  phase of a  program  to  develop  Ground
Penetrating  Radar (GPR)  production  prototype system to detect precious metals
and minerals in subterranean  locations.  Contract terms call for the Company to
develop and deliver an operational GPR sensor assembly, designated the "Seeker,"
as the first phase of a complete  portable  system that will identify and target
gold deposits behind mine walls. The goal is to detect gold at distances of more
than 10 feet beyond the mine tunnel wall surface. Recent propagation tests in an
operational gold mine produced  encouraging  results. The project is expected to
be completed  within calendar year 1997.* The funds payable to the Company under
this joint venture are payable on a milestone basis. Therefore, in the event the
Company is unable to achieve  the  milestones,  it will not  realize all of such
revenue. The failure to meet the required milestones under the LandRay agreement
would have a material adverse effect on the Company's  results of operations and
financial condition.  To date approximately  $450,000 has been raised by LandRay
to fund the $1.2 million contract. Of that amount, $250,000 has been paid to the
Company.  Receipt of the balance of the contract  revenue is also dependent upon
the ability of LandRay to raise the  balance of the funds  needed to fulfill the
contract obligations

         On  April  10,  1997 the  Company  closed  on a  private  placement  of
4,370,000  shares of its Common  Stock with gross  proceeds of  $1,092,500.  The
Company  agreed to pay a selling  agent a placement fee equal to 5% of the gross
proceeds of the  offering.  In  addition  the Company has agreed to issue to the
selling agent  Warrants to purchase  Common Stock in a number of shares equal to
5% of the total  number of shares  sold in the  offering.  The  selling  agent's
Warrants will be  exercisable at $0.25 per Share (equal to the offering price of
the shares) and will be exercisable for a period of five years.  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.

Factors Affecting Operating Results and Market Price of Stock

Power Spectra operates in a rapidly changing  environment that involves a number
of uncertainties, some of which are beyond the Company's control. In addition to
the  uncertainties  described  elsewhere  in this  report,  these  uncertainties
include:

History of Losses;  Accumulated  Deficit.  Since its inception,  the Company has
generally operated at a loss as 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
($3,788,299),  ($2,562,230)  and  ($1,112,507)  for the years ended December 31,
1996,  December 31, 1995 and December  31, 1994,  respectively.  At December 31,
1996, the Company had an accumulated deficit of $15,062,956. The Company expects
that it will  continue to incur losses for the  foreseeable  future and does not
expect to become profitable 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.

*This statement is a forward-looking  statement reflecting current expectations.
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"  for a discussion of
factors that could affect future performance.

                                       15
<PAGE>

Product  Development and  Enhancements.  The development of high power switching
components and products, and the development of commercial applications for such
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.  There is no assurance that the
Company will succeed in this effort.

Complex  Manufacturing  Process.  The manufacture of  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  perrformance  of personnel and  equipment.  The
Company  has  periodically  experienced  yield  problems,  and  there  can be no
assurance  that these  problems  will not recur.  Should the Company  experience
protracted  production  delays  attributable to  manufacturing  complexity,  its
ability to deliver products would be materially affected.

Historical  Dependence  on Boeing  Relationship.  From October 1988 through July
1994, the Company  received  approximately  $23,500,000 in research funding from
Boeing  Electronics   Company  for  development  and  enhancement  of  the  BASS
technology and products.  In the years ended  December 31, 1994,  1993 and 1992,
the  Company  recognized  revenues of  $1,600,000,  $3,100,000  and  $3,700,000,
respectively,  in connection  with the Boeing Research  Agreement.  Although the
Company successfully completed several contracts throughout the duration of this
relationship,  during  1994,  Boeing  made the  strategic  decision to focus its
resources on its missile and aircraft business. As part of this decision, Boeing
reorganized  its  electronics  company and  consolidated it with its Defense and
Space Group.  The Company will have to look to  alternative  revenue  sources to
replace  the  revenues  generated  by the Boeing  relationship,  and there is no
assurance that the Company will successfully be able to do so in the short-term,
if at all.

Dependence on Boeing Equipment.  Boeing has granted the Company the right to use
its  equipment on a loaned basis for the Company's  purposes,  subject to annual
renewal. Additionally,  should the Company desire to acquire title and ownership
of the  loaned  equipment,  Boeing and the  Company  will  attempt to  negotiate
appropriate  consideration  in return for the  transfer of title and  ownership.
However, there is no assurance that an agreement satisfactory to the Company can
be reached. If Boeing chooses to no longer loan the equipment to the Company, as
it may do in its sole discretion,  and an acceptable agreement for the Company's
purchase of the equipment  cannot be attained,  the Company would be required to
find  alternative  sources of  equipment,  either for purchase or rent, or would
have to outsource its manufacturing while still in possession of a manufacturing
facility.  Any of these  circumstances 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.

Expiration of Air Force Contract.  The Company's contract with the United States
Air Force expired in June 1996, and such contract has been a significant  source
of revenues since it was awarded to the Company in 1990. The aggregate  contract
value  has  increased  over  the  period  of the  contract,  from  the  Phase  I
cost-plus-fixed-fee  value of $5,192,744 to  $10,517,881 as of February 8, 1995.
With  the  termination  of the  Air  Force  Contract,  it is  necessary  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 the equity  financings
will be sufficient to allow the Company to support its operating expenses.

Dependence on Government Contracts. A material portion of the Company's business
has  historically  resulted  from  contracts  with or for  government  agencies.
Although the Air Force  Contract  expired in 1996,  the Company  hopes to obtain
additional  government  contract work in the future.  Competition for government
development contracts is intense, and no assurance can be given that the Company
will be able to secure significant government contracts in the future. 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  prospects of obtaining  significant
government development contracts.

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

                                       16

<PAGE>

of domestic and foreign patents covering various aspects of its BASS technology,
but  has  no  patents  or  patent  applications  pending  on  its  PSIristor(TM)
technology. 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.
There can be no assurance,  however,  that others will not independently develop
superior  know-how or obtain  access to know-how  and trade  secrets used by the
Company that the Company now considers proprietary.

Future  Reliance  upon  Distributors.   Historically,  the  Company  has  relied
primarily  upon a  direct  sales  organization  and,  to a lesser  extent,  upon
manufacturers'  representatives to sell and distribute its commercial  products.
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 to a far greater degree
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 it 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 highly competitive and
characterized by rapid technological  change,  sudden price fluctuations,  rapid
rates of product obsolescence, periodic shortages of materials and variations in
manufacturing  yields and efficiencies.  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.  Most  of the  Company's
competitors have substantially greater financial, technical, marketing and other
resources than does the Company.  Principal  competitive  factors include price,
performance and features.  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.

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.  As
part of this strategy,  the Company recently negotiated a joint venture,  called
PEAC Airborne  Technologies,  Inc. and completed the formation of a second joint
venture, called LandRay Technologies, Inc. Both ventures will require additional
funding in order to enable the Company and its joint  venture  partners to carry
out their respective plans of operations.  PEAC is initially seeking  $7,000,000
in equity financing. If the offering is successfully completed, the Company will
receive a portion of the net  proceeds  to  develop  its  ultra-wideband  ground
penetrating  radar  ("UWB  GPR")  technologies.  Failure  of PEAC to  raise  the
necessary  financing  will  have a  material  adverse  impact  on the  Company's
revenues and cash flows. Although the Company has entered into the LandRay joint
venture,  its success is dependent upon demonstrating the feasibility of UWB GPR
systems capable of locating and identifying minerals and oil and gas formations.
There is no assurance  that LandRay and the Company will be  successful  in this
regard.  Failure  of LandRay  and the  Company to  adequately  demonstrate  such
feasibility  will have a material  adverse impact on the Company's  revenues and
cash flows. There can be no assurances that the proposed PEAC joint venture will
be  consummated,  that the PEAC and LandRay joint ventures will be able to raise
adequate  funding  on  acceptable  terms,  that  the  Company  will  be  able to
successfully  enter into any  additional  suitable  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  revenues  previously  generated  by the Air
Force  contract.  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.

Volatility  of Stock  Price.  The  market  price of the  Common  Stock is highly
volatile.  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  substantially.  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.

                                       17
<PAGE>

The price of the Company's  Common Stock is particularly  susceptible to extreme
fluctuation  because  of thin  trading  volume in the  Common  Stock and lack of
widely available pricing information.

No Assurance of Nasdaq Trading.  The Company's  Common Stock is currently traded
in dealer  transactions  on the  Electronic  Bulletin  Board  maintained  by the
National Quotation Bureau,  Inc., an over-the-counter  market in which liquidity
is typically limited and price volatility can be great. The Electronic  Bulletin
Board is generally considered to be a less efficient market because, among other
reasons,  it does not automatically  provide real time quotation.  The Company's
Common Stock is currently  not  eligible  for  quotation on The Nasdaq  SmallCap
Market,  and there is no assurance  that the Company  will meet the  eligibility
requirements for quotation on Nasdaq in the foreseeable future.


ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

         The  information  required by this Item is  incorporated  by  reference
herein from , Item 14(a)(1).


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
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 in the future.

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 dutites 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  share per fiscal year,  provided,  however,  that new hires may receive
additional  option  grants for no more than 300,000  shares in the 

                                       22
<PAGE>

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.  As of March
31, 1996, options to purchase 9,500 shares had been granted under the 1996 Plan,
and 1,614,176 shares were available for future grants.

         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 voing 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 and 200,000 shares in the number of shares available
for  issuance  under the Stock  Plan in June 1993 and June  1995,  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 th preceding 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 share  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 1996.  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.

Compliance with Section 16(a) of the Exchange Act

         Based  solely on its review of the copies of Forms 3,4,  and 5 received
by the Company, or written  representations  from certain reporting persons that
no Forms 5 were required for such persons, the Company believes that, during the
fiscal year ended December 31, 1996, all filing requirements under Section 16(a)
of the  Securities  Exchange Act  applicable to its officers,  directors and 10%
shareholders were complied with.

ITEM 13. CERTAIN  RELATIONSHIPS AND RELATED TRANSACTIONS

Sale of Common Stock

         Between  August  1995 and March  1996,  the  Company  sold units of its
securities  ("Units")  with  an  aggregate  value  of  $5,960,000  in a  private
placement  priced  at $1.10  per  Unit  (the  "Private  Placement").  Each  Unit
consisted  of one share of Common Stock of the Company and a warrant to purchase
one-half of one share of Common  Stock.  The Company  issues  Common  Stock,  or
securities  convertible  into Common  Stock,  at a price per share less than the
offering  price of the Units (the  "Subsequent  Offering  Price"),  the warrants
issued  pursuant to the Private  Placement  become  exercisable as to 50% of the
underlying  shares at the Subsequent  Offering  Price.  The warrants will become
exercisable  as to the remainder of the  underlying  shares at the Unit offering
price if the Company's  Common Stock is not listed on the Nasdaq National Market
or the Nasdaq  Small Cap Market  within two years of the  issuance  date of such
warrants.  The Company also agreed to register the Common Stock issued  pursuant
to the Private  Placement with the Securities  and Exchange  Commission,  and to
indemnify  the holders of such Common  Stock under  certain  circumstances.  For
further  information,  see Note 5 to the financial statements included with this
Report.

         Among the entities  purchasing Units were entities  associated with the
Travelers' Group,  Inc., a holder of more than 10% of the Company's  outstanding
shares of Common Stock,  which purchased  2,727,272 Units.  Michael I. Gamble, a
director  and former  President  and Chief  Executive  Officer  of the  Company,
purchased 10,000 Units and Gene J. Kennedy, a director of the Company, purchased
20,000 Units.

Severance Agreement with Executive Officer

         On June 1, 1996, the Company entered into an employment termination and
mutual release agreement with Michael I. Gamble,  its former President and Chief
Executive Officer,  and a director of the Company.  The agreement provides for a
one-time  payment of $105,000 to Mr. Gamble.  The Company also agreed to pay Mr.
Gamble's medical insurance  premiums through December 31, 1996, and certain fees
for outplacement services and moving expenses.  The terms of options to purchase
Common Stock held by Mr. Gamble were extended to May 31, 1998.

         In addition, the Company and Mr. Gamble agreed that Mr. Gamble would be
available  to provide  consulting  services  to the  Company for 13 days in each
two-month  period  through May 31, 1997.  The Company  agreed to pay Mr.  Gamble
$692.32  for each day he makes  himself  available  to  provide  such  services,
whether or not the Company uses his  services.  For the period from June 1, 1997
to May 31, 1998, Mr. Gamble will provide  consulting  services to the Company as
mutually agreed by the parties from time to time.

         Mr. Gamble agreed to waive any other rights or claims he may have based
on his employment relationship with the Company.

                         Report of Independent Auditors


Board of Directors and Stockholders
Power Spectra, Inc.


We have audited the accompanying statements of operations, stockholders' equity,
and cash flows of Power  Spectra,  Inc.,  for the year ended  December 31, 1994.
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 audit.

We conducted our audit 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 audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all  material  respects,  the results of  operations,  changes in  stockholders'
equity and cash flows of Power  Spectra,  Inc.,  for the year ended December 31,
1994, in conformity with generally accepted accounting principles.

The Company's recurring losses from operations raise substantial doubt about its
ability to continue as a going concern.  The Company's cash position at December
31, 1994, together with anticipated cash flows from operations and new financing
through the issuance of Series B Preferred  Stock, are expected by management to
be  sufficient to finance the Company's  operations  through  December 31, 1995.
However,  if the Company is not  successful  in  replacing  the revenue and cash
generated by the Boeing Agreement and the United States Air Force contract,  the
Company, as presently sized, would continue to experience  significant operating
losses.  The 1994 financial  statements have been prepared on the basis that the
Company will continue as a going concern and do not include any adjustments that
might result from the outcome of this uncertainty.

                          Notes to Financial Statements

                                December 31, 1996


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 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 with U.S. Government agencies.

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.  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.

A material portion of the Company's  historical  business results from contracts
with or for government agencies.  There can be no assurances that the Government
will  continue  to fund such  contracts  or that the  Company  will  prevail and
capture such contracts if funded.  Additionally,  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 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 Company's  growth  strategy  includes the successful  completion of products
under development, development of new applications, and development of marketing
strategies.

The Company's  current cash position,  together with anticipated cash flows from
operations and new financing  through the issuance of Common Stock, are expected
by  management to be  sufficient  to finance the  Company's  operations  through
December 31, 1997.*  However,  the actual amount of time that the Company's cash
resources  last is dependent  upon a variety of factors  including the timing of
obtaining  new  contracts,  the  timing of new  financings,  the  success of its
current joint ventures and the  competition  with other vendors.  If the Company
determines that it requires  additional  funds prior to December 31, 1997, there
can be no assurance  that  additional  funds will be  obtainable  on  reasonable
terms,  or at all. Any such failure could result in the Company  becoming unable
to meet its  obligations  as they come due. If the Company is not  successful in
replacing  the revenue and cash  generated by the Boeing  Agreement  and the Air
Force Contract,  the Company would continue to experience  significant operating
losses. The Company does not presently have access to any credit facilities.

- ----------------------
*This statement is a forward-looking  statement reflecting current expectations.
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"  for a discussion of
factors that could affect future performance.

Depreciation

Depreciation  is provided  using the  straight-line  method  over the  estimated
useful lives of the assets (3 to 10 years).

Patents

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

Research and development contract revenue

Contract revenues are recognized on the percentage-of-completion method based on
costs incurred.

Deferred revenues

Deferred  revenues  are  payments  made by  customers  for which the Company has
deferred revenue recognition until the contract is closed out.

Loss per common 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 1996 and 1995, and
after deducting Series A Preferred Stock dividends in 1994. Shares issuable upon
exercise  of stock  options  have not been  included in the  calculation  as the
effect would be anti-dilutive. The Series A and Series B Preferred Stock are not
included as their effects are anti-dilutive on an as-if-converted basis.

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,  1996,  Company
contributions to the plan were $12,660 (1995--$12,457, 1994--$8,785).

2.  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 to 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.

3.  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.

4.  Taxes on income

A reconciliation  between the Company's effective tax rate and the United States
("U. S.") statutory rate (34%) is as follows:

                                                 Year ended December 31,

                                          ----           ----            ----

                                       ===========    ===========    ===========

At December  31,  1996,  the Company had net loss  operating  carryforwards  for
federal  and  state  income  tax  purposes  of  approximately   $13,500,000  and
$3,800,000,  respectively.  The Company also had 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.

Significant  components of the Company's deferred tax assets and liabilities for
U. S. federal and state income taxes are as follows:

                                                           December 31,

5.  Common Stock

In August 1995 the Company  initiated a private  placement  of its common  stock
with a maximum gross proceeds to be raised from the offering of $6,000,000.  The
placement  closed at March 29, 1996.  Gross proceeds raised through December 31,
1995 were $3,694,000 and gross proceeds through March 31, 1996 were $5,960,000.

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 described below. 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
only under the following circumstances and only to the following extent:

         (i) 50% of the  total  number of  warrants  held by the  investor  will
         become  exercisable  if,  within three years of the  original  issuance
         date,  the Company issues common stock or securities  convertible  into
         common  stock at a price below the unit  offering  price.  The exercise
         price of such  warrants  vested in accordance  with this  paragraph (i)
         will be equal to the price offered to the  investors in the  subsequent
         financing.

                                       F-11

6.  Common Stock (continued)

         (ii) 50% of the total  number of  warrants  held by the  investor  will
         become  exercisable if, within two years of the original issuance date,
         the Company's  common stock is not quoted on the NASDAQ SmallCap Market
         (or, at the Company's sole discretion, 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.

         The company has further  agreed that for three years from the  original
         issuance  date,  it will not grant any stock options under its existing
         or future stock option plans at an exercise price less than 110% of the
         unit  offering  price.  This  plan  provision  may only be  amended  or
         rescinded by the approval of the outstanding shareholders.

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 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.

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 72,138 shares under
the Director Plan during 1996 (1995 --89,965, 1994 -- 90,924 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  3,000  shares of Common  Stock under the  Advisory  Board Stock
Program  in 1996 at $1.03 per share  (1995 -- issued 4, 000 at $0.88 per  share,
1994 -- issued 9,000 shares of Common Stock at $0.94 to $1.25 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) 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.
Effective  with the approval of the 1996 Plan the 1986 Plan was terminated as to
future  grants,  and the shares  reserved for issuance under such Plan were made
available  for issuance  under the 1996 Plan.  Any reserved  shares that are not
issued as a result of the  termination  of existing  options under the 1986 Plan
before they are exercised, will also be available for grant under the 1996 Plan.
Such  termination  will not  affect the  shares  subject  to  options  currently
outstanding  under the 1986 Plan.  At  December  31,  1996,  there were  811,458
options issued and outstanding  under the 1986 Plan and 9,500 options issued and
outstanding under the 1996 Plan.

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 70,000 stock shares of Common Stock under the Director Option
Plan in 1996 at $1.85 per share (in 1995  granted  70,000  options  at $1.16 per
share and in 1994 granted  options to acquire  60,000  shares of Common Stock at
$1.13 per share).

6. Common Stock (continued)

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.

                                                    1995             1996

The fair value of each option  grant is estimated on the date of grant using the
Black  Scholes   options-pricing  model  with  the  following   weighted-average
assumptions  used  for  grants  in 1995  and  1996,  respectively:  no  expected
dividends; expected volatility of 200%; weighted average risk-free interest rate
of 6.55%; and expected lives of 5 years.

A summary of the status of the  company's  stock option plan for the three years
ended December 31, 1996, and changes during those years is presented below.

7.  Development and marketing agreement

In 1991, the Company  received from The Boeing Company  ("Boeing")  $2.8 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. Accordingly,  these assets
are  considered  to be on loan from  Boeing  and have not been  recorded  in the
accompanying  balance  sheets.  On an  annual  basis,  Boeing  will  review  the
Company's  continued  use of these assets and such assets may either be returned
to Boeing or purchased, at the Company's option, for an amount to be negotiated.
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 for $20,868 per month until February 1997.

In connection with an agreement with Boeing for the development of the Company's
Bulk Avalanche  Semiconductor  Switch (BASS) device, the Company recognized $1.6
million in revenue in 1994. This agreement expired June 30, 1994.

8.  Operating leases

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

                           1997                                 29,001

                                                             =========

For  the  year  ended  December  31,  1996,  rent  expense  was  $250,413  (1995
- --$250,413, 1994 -- $250,413).

10.  Subsequent Events

         Subsequent  to  year  end,  the  Company  entered  into a $1.2  million
contract with LandRay Technologies,  Inc. ("LandRay"), a joint venture partially
owned  by the  Company,  as the  first  phase of a  program  to  develop  Ground
Penetrating  Radar (GPR)  production  prototype system to detect precious metals
and minerals in subterranean  locations.  Contract terms call for the Company to
develop and deliver an operational GPR sensor assembly, designated the "Seeker,"
as the first phase of a complete  portable  system that will identify and target
gold deposits behind mine walls. The goal is to detect gold at distances of more
than 10 feet beyond the mine tunnel wall surface. Recent propagation tests in an
operational gold mine produced  encouraging  results. The project is expected to
be completed  within calendar year 1997.* The funds payable to the Company under
this joint venture are payable on a milestone basis. Therefore, in the event the
Company is unable to achieve  the  milestones,  it will not  realize all of such
revenue. The failure to meet the required milestones under the LandRay agreement
would have a material adverse effect on the Company's  results of operations and
financial condition.  To date approximately  $450,000 has been raised by LandRay
to fund the $1.2 million contract. Of that amount, $250,000 has been paid to the
Company.  Receipt of the balance of the contract  revenue is also dependent upon
the ability of LandRay to raise the  balance of the funds  needed to fulfill the
contract obligations

On April 10, 1997 the Company closed on a private  placement of 4,370,000 shares
of its Common Stock with gross proceeds of $1,092,500. The Company agreed to pay
a  selling  agent a  placement  fee  equal to 5% of the  gross  proceeds  of the
offering.  In addition  the  Company  has agreed to issue to the  selling  agent
Warrants to purchase Common Stock in a number of shares equal to 5% of the total
number of shares sold in the  offering.  The selling  agent's  Warrants  will be
exercisable  at $0.25 per share (equal to the offering  price of the shares) and
will be  exercisable  for a period of five  years.  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.

                  "This corporation is authorized to issue two classes of shares
                  of stock to be  designated  as "Common  Stock" and  "Preferred
                  Stock." The total  number of shares that this  corporation  is
                  authorized  to issue is sixty million  (60,000,000),  of which
                  fifty-five  million  (55,000,000)  shall be designated  Common
                  Stock  and  five  million   (5,000,000)  shall  be  designated
                  Preferred  Stock.  The Preferred Stock may be issued in series
                  with   rights,    preferences,    privileges,    restrictions,
                  designation and number of shares as determined by the board of
                  directors."

directors and the required vote of  shareholders in accordance with Sections 902

Power Spectra, Inc.
919 Hermosa Court
Sunnyvale, CA 94086
Attn: Chuck Byer

Gentlemen:

This letter is a formal amendment to that certain GPR System  Development,  Sale
and License Agreement  between LandRay  Technology,  Inc.  ("LandRay") and Power
Spectra,  Inc., ("PSI") dated as of December 17, 1996 (the "Agreement").  Except
as set forth herein,  the Agreement  shall remain in full force and effect.  All
capitalized  terms not otherwise defined herein shall have the meanings ascribed
to them in the Agreement.

The intent of this amendment is to restructure  certain  aspects of the existing
Agreement,  which  presently  provides  for  a  $3,000,000  payment  by  us  and
concurrent  performance  by you on a number of  different  aspects  of the GPRS.
Because of mutual resource limitations,  we both want to restructure the program
into a series of three  manageable  projects  or steps  which  are  independent,
sequential,  and  optional on  LandRay's  part,  to provide for  certainty  with
respect to the grant to us of manufacturing rights on a project-by-project basis
to be effective  upon the bankruptcy of PSI or the failure of PSI to deliver GPR
Products  based upon agreed  schedules  per  Exhibits D-1 and D-2, to change the
cure period and to effect other clean- up items.

To implement that intent:

1. Section 4.1 of the Agreement is amended to read in full as follows:

     LandRay will pay PSI the sum of up to $3,000,000 (the "Contract Price") for
     the  development of the work to be performed  hereunder.  Such payment will
     occur in three discrete,  independent steps. The first step,  involving the
     payment of $1,200,000  shall have up to five  tranches.  The first $250,000
     payable by LandRay  within ten business  days after the date hereof,  shall
     confirm to LandRay the irrevocability of the license :

     grant  referred to in  Paragraph 5. l(d) hereof with respect to the Seeker;
     the  remaining  balance of  $950,000  for this step  shall be payable  upon
     achievement  of the  milestones  set forth in Exhibit D-1 attached  hereto.
     Upon  completion of (i) a complete  technical  data package with respect to
     the Seeker,  and (ii)  delivery of one finished  Seeker unit, LandRay shall
     have six  months  to  exercise  its  option to pursue  the  Imager  and the
     Borehole-to-Borehole  applications  of the Imager for an aggregate price of
     $1,800,000  payable upon achievement of milestones with respect thereto set
     forth on Exhibit D-2 attached  hereto.  The  aforementioned  technical data
     package shall be reviewed for approval by LandRay (which  approval will not
     be  unreasonably  withheld,  and  which  shall  be done  within  30 days of
     submittal  to  LandRay)  and will be kept in a secure  place for  immediate
     release to LandRay as provided for in Section 5.1(d)  hereof.  All payments
     set forth on  Exhibits  D-1 and D-2  shall be due and  payable  within  ten
     business days after the respective events set forth therein. If LandRay has
     not   exercised   its   option   to   pursue   steps   2   (Imager)   or  3
     (Borehole-to-Borehole)  within six months after  completion of the delivery
     of the Seeker and the related  technical  data package,  then LandRay shall
     lose its rights with respect to the unexercised option(s).

2.   Paragraph  5. l(a) is hereby  amended to encompass  one license  grant with
     respect  to the  Seeker  for the  licensed  applications  upon the  initial
     payment of $250,000,  and a second and third  license grant with respect to
     the   "Imager"  and  the   "Borehole-to-Borehole"   GPR  for  the  licensed
     applications upon the initial payment therefor as contemplated hereunder.

3.   The  second  sentence  of  Section  5.l(a)  is  amended  to read in full as
     follows:

     During the term hereof, PSI shall not make available to any third party any
     rights under the GPR Patents or the GPR Know-How,  or make available to any
     third party any products  which are the  functional  equivalents of the GPR
     products, in either case for the licensed applications.


4.   Paragraph  5.1(d) is amended to provide  for a 60 day cure period on line 5
     and to include  the word  "automatically"  between  the words  "shall"  and
     "include" in line 7. PSI shall deliver the technical data package with

<PAGE>

Power Spectra, Inc. Contract Amendment

Page 3

     sufficient  content and detail to permit LandRay to manufacture the subject
     device (Seeker, Imager and/or Borehole-to-Borehole,  as appropriate) either
     internally  or  by  contract  manufacturer  without  additional  consulting
     assistance.

5.   Paragraph 5.3(a) shall be amended to read in full as follows:

     Following  delivery of the PSI  Deliverables  to LandRay and LandRay's full
     payment  of the  Contract  Price and other fees set forth in Article 4 with
     respect to that independent phase,  LandRay shall take title to, and become
     the exclusive owner of, the PSI Deliverables delivered with respect to that
     phase.

6.   The  reference  to the  number  "forty-five  (45)"  in the  second  line of
     Paragraph 7.2 shall be amended to "sixty (60)".

7.   In  Article  13,  the  following  sentence  shall be added  after the third
     sentence:

     "PSI shall manufacture GPR products upon receipt of LandRay's  order(s) and
     provide prompt delivery;"

     the following  clause shall be added to the fifth  sentence,  on line nine,
     between the words "GPR Products" and "and":

     "(calculated using standard product cost accounting methods)"

     and the following  clause shall be added to the end of the fifth  sentence,
     following the word "margin":

     "(not to exceed 20%)"

8.   The  second  line of Section  15.8 is  amended to read in full as  follows:
     "...bankruptcy   rejects  this  Agreement.   LandRay's  rights  under  this
     Agreement shall be as..."

9.   The reference in Section  7.4(c) to "Section 7.6" (which does not exist) is
     to be changed to refer to "Section 7.5".

10.  In reviewing the relevant  documentation,  we noted an  awkwardness  in the
     identification  of the parties to the  original  Ground  Penetrating  Radar
     Development  Agreement  dated June 19, 1996 (the "Initial  Agreement").  By
     this letter we each confirm that the parties to the Initial  Agreement  are
     only PSI and LandRay,  acting by and through  third parties for the benefit
     of LandRay.

11.  The Initial Agreement provides for an anti-dilution minimum of 25% for PSI.
     PSI hereby agrees to reduce its  anti-dilution  minimum to 22.67%,  and the
     parties  agree to  resolve  any  further  reduction  of this  anti-dilution
     minimum by future amendment.

Please sign and return the  enclosed  copy of this letter to evidence an initial
agreement with respect to the amendment of the Agreement.

                               Very truly yours,
                               LANDRAY TECHNOLOGY, INC.

1. LandRay, Phase 3 Contract Amendment executed $250,000

2. Milestone 2                                  $250,000

3. Milestone 3

[Milestones  from  Seeker  Development  Plan should be listed  here,  in roughly
$250,000  increments,  with the final  payment  for the final  deliverable.  The
present  interim seeker plan is not clear on "Interim  Seeker"  description  and
delivery  schedule.  Suggested  milestones  should include delivery of a defined
"Interim  Seeker"  and  the  final  "Production  Seeker",   along  with  interim
milestones  to link funding with some sort of definable  progress --  milestones
can refer to the GANTT  schedule Task ID line numbers.  These are issues we need
to clarify,  but we can't hold up the funding  process to do so.  Therefore,  we
agree to detail this to our mutual satisfaction at the earliest possible date.]

EXHIBIT D-2

This  needs  to be open at this  point - We  don't  have a good  picture  of the
milestones  and schedule,  but during the progress of the Seeker  development we
will be able to put this  together.  We can agree to the  amount  of  $1,800,000
subject to the  escalation  clause,  but it would be  unrealistic to button down
specifics at this point.  We agree to agree on a schedule along the lines of the
Seeker  funding  concept,  and to do so by the  time the 6 month  option  period
begins.

amended.

                  (b) The terms  "register,"  "registered,"  and  "registration"

statement  in  compliance  with  the Act  and the  declaration  or  ordering  of

         1.2  Registrable  of  Registrable  Securities.  Within  six (6)  months
following  the final  closing of the  Offering,  the Company  shall use its best
efforts to file a registration  statement under the Act covering the Registrable
Securities  and to use its  further  best  efforts  to cause  such  registration
statement to be declared  effective by the Securities  and Exchange  Commission.
The Company is  obligated to effect only one (1)  registration  pursuant to this
Section  1.2  unless  the  Company  fails  to  effect  the  registration  of all
Registrable  Securities  for  which  registration  is  required  and  have  such
registration declared or ordered effective.

         1.3 Obligations of the Company.  Whenever  required under Paragraph 1.2
to  use  its  best  efforts  to  effect  the  registration  of  any  Registrable
Securities, the Company shall, as expeditiously as reasonably possible:

                  (a)  Prepare  and  file  with  the   Securities  and  Exchange
Commission  (the  "Commission")  a  registration  statement with respect to such
Registrable  Securities  and use its best  efforts  to cause  such  registration
statement to be declared or ordered effective.

                  (b) Prepare and file with the Commission  such  amendments and
supplements to such registration statement and the prospectus used in connection
with such  registration  statement as may be necessary to keep such registration
statement effective for a period ending the earlier of (i) the completion of the
distribution  of  the  Registrable   Securities  included  in  the  registration
statement or (ii) one year from the date hereof.

                  (c)  Furnish  to  the  Holder  such  numbers  of  copies  of a
prospectus,   including  a  preliminary  prospectus,   in  conformity  with  the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

                  (d)  Use  its  best   efforts  to  register  and  qualify  the
securities covered by such registration statement under such other securities or
Blue Sky laws of such  jurisdictions as shall be reasonably  appropriate for the
distribution of the securities covered by the registration  statement,  provided
that the Company shall not be required in connection therewith or as a condition
thereto  to qualify to do  business  or to file a general  consent to service or
process in any such states or jurisdictions, and further provided that (anything
in this Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any  jurisdiction in which the securities  shall be qualified shall
require that  expenses  incurred in  connection  with the  qualification  of the
securities  in that  jurisdiction  be borne by selling  shareholders,  then such
expenses  shall be  payable  by  selling  shareholders  pro rata,  to the extent
required by such jurisdiction.

                  (e) Use its best  efforts  to  maintain  a current  prospectus
allowing the resale of the Shares covered by the  registration  statement for so
long  as  any  of the  Registrable  Securities  remain  unsold  pursuant  to the
prospectus,  subject to termination of this obligation as set forth in paragraph
1.8, below.

                                       2
<PAGE>

         1.4  Furnish  Information.  It shall be a  condition  preceding  to the
obligations  of the Company to take any action  pursuant to this Agreement as to
any Holder  that such  Holder  shall  furnish to the  Company  such  information
regarding  him or it,  the  Registrable  Securities  held by him or it,  and the
intended  method  of  disposition  of  such  securities  as  the  Company  shall
reasonably  request and as shall be requested or required by the  Commission  or
otherwise in connection with the action to be taken by the Company.

         1.5 Expenses of Registration.  All expenses incurred in connection with
registration pursuant to Paragraph 1.2 hereof (excluding underwriters' discounts
and  commissions),   including,   without   limitation,   all  registration  and
qualification fees, printers' and accounting fees, and fees and disbursements of
counsel for the Company, shall be borne by the Company.

         1.6 Delay of Registration.  Notwithstanding any other provision of this
Agreement, no Holder shall have any right to take any action to restrain, enjoin
or otherwise delay any  registration as the result of any controversy that might
arise with respect to the interpretation or implementation of this Agreement.

         1.7  Indemnification.  In the  event  any  Registrable  Securities  are
included in a registration statement under this Agreement:

                  (a) To the extent permitted by law, the Company will indemnify
each Holder,  each of its officers and directors  and partners,  and each person
controlling  such  Holder  within the  meaning  of  Section 15 of the Act,  with
respect to which  registration,  qualification  or compliance  has been effected
pursuant to this Agreement,  and each  underwriter,  if any, and each person who
controls any  underwriter  within the meaning of Section 15 of the Act,  against
all expenses,  claims,  losses,  damages and  liabilities (or actions in respect
thereof),  including  any  of  the  foregoing  incurred  in  settlement  of  any
litigation,  commenced  or  threatened,  arising  out of or based on any  untrue
statement (or alleged  untrue  statement)  of a material  fact  contained in any
registration statement,  prospectus, offering circular or other document, or any
amendment   or   supplement   thereto,   incident  to  any  such   registration,
qualification  or  compliance,  or any omission  (or alleged  omission) to state
therein a material fact  required to be stated  therein or necessary to make the
statements  therein,  in light of the circumstances in which they were made, not
misleading, or any violation by the Company of the Act or any rule or regulation
promulgated  under the Act applicable to the Company in connection with any such
registration,  qualification or compliance,  and the Company will reimburse each
such Holder,  each of its officers and directors  and partners,  and each person
controlling such Holder,  each such underwriter and each person who controls any
such underwriter,  for any legal and any other expenses  reasonably  incurred in
connection  with  investigating,  preparing or defending  any such claim,  loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage,  liability or expense
arises out of or is based on any untrue  statement or omission or alleged untrue
statement or alleged  omission,  made in reliance  upon and in  conformity  with
written information furnished to the Company by such Holder, officer,  director,
partner, controlling person or underwriter and stated to be specifically for use
therein.

                                       3

<PAGE>

                  (b) To the  extent  required  by law,  each  Holder  will,  if
Registrable  Securities held by such Holder are included in the securities as to
which  such  registration,   qualification  or  compliance  is  being  effected,
indemnify the Company,  each of its officers and directors,  each underwriter of
the Company's securities covered by such a registration  statement,  each person
who controls the Company or such  underwriting  within the meaning of Section 15
of the Act, and each other such Holder,  each of its officers and  directors and
partners and each person  controlling  such Holder within the meaning of Section
15 of the Act, against all expenses, claims, losses, damages and liabilities (or
actions  in  respect  thereof),  including  any of  the  foregoing  incurred  in
settlement of any litigation,  commenced or threatened,  arising out of or based
on any untrue  statement  (or  alleged  untrue  statement)  of a  material  fact
contained in any registration statement,  prospectus, offering circular or other
document, or any amendment or supplement thereto, incident to such registration,
qualification  or  compliance,  or any omission  (or alleged  omission) to state
therein a material fact  required to be stated  therein or necessary to make the
statements therein not misleading, and will reimburse the Company, such Holders,
such directors, officers, partners, persons, underwriters or control persons for
any  legal  or  any  other  expenses  reasonably  incurred  in  connection  with
investigating, preparing or defending any such claim, loss, damage, liability or
action,  in each case to the extent,  but only to the  extent,  that such untrue
statement (or alleged untrue statement) or omission (or allege omission) is made
in such registration statement,  prospectus, offering circular or other document
in reliance upon and in  conformity  with written  information  furnished to the
Company  by any  instrument  duly  executed  by such  Holder  and  stated  to be
specifically for use therein.  Notwithstanding  the foregoing,  the liability of
each Holder under this subsection (b) shall be limited in an amount equal to the
initial  public  offering  price of the shares sold by such Holder,  unless such
liability arises out of or is based on willful conduct by such Holder.

                  (c)  Each  party  entitled  to   indemnification   under  this
Paragraph 1.7 (the "Indemnified  Party") shall give notice to the party required
to  provide  indemnification  (the  "Indemnifying  Party")  promptly  after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought,  and shall  permit the  Indemnifying  Party to assume the defense of any
such claim or any litigation resulting therefrom;  provided that counsel for the
Indemnifying  Party,  who shall conduct the defense of such claim or litigation,
shall  be  approved  by  the   Indemnified   Party  (whose  approval  shall  not
unreasonably  be withheld),  and the  Indemnified  Party may participate in such
defense at such party's  expense;  and provided  further that the failure of any
Indemnified  Party to give  notice as  provided  herein  shall not  relieve  the
Indemnifying Party of its obligations under this Agreement unless the failure to
give such notice is materially  prejudicial to an Indemnified Party's ability to
defend such action;  and provided further that the Indemnifying  Party shall not
assume the  defense  for  matters as to which there is a conflict of interest or
separate and different  defenses.  No Indemnifying  Party, in the defense of any
such claim or  litigation,  shall,  except with the consent of each  Indemnified
Party,  consent to entry of any judgment or enter into any settlement which does
not  include as an  unconditional  term  thereof  the giving by the  claimant or
plaintiff to such  Indemnified  Party of a release from all liability in respect
to such claim or litigation.

         1.8 Termination of the Company's Obligations. The Company shall have no
obligations  pursuant to Paragraph  1.2 if the benefits of Rule 144  promulgated
under the Act as  currently in effect or any other  similar  rule or  regulation
that may  hereinafter be enacted by the  Commission  permitting a Holder to sell
securities  of the  Company  to the  public  without  registration  on terms and
conditions  as beneficial to the Holder as those of Rule 144 as it exists at the
date of this Agreement, are available to the Holder, then the Company shall have
no  obligation  to register  securities  (or  continue to maintain an  effective
registration  statement covering the resale of such securities) pursuant to this
Agreement  to any Holder who owns less than one  percent  (1%) of the  Company's
Common Stock (on a fully  diluted  basis) and whose sales are not required to be
aggregated with others.

         1.9 Reports under the Securities  Exchange Act of 1934.  With a view to
making  available to the Holders the benefits of Rule 144 promulgated  under the
Act and any other  rule or  regulation  of the  Commission  that may at any time
permit  a  Holder  to sell  securities  of the  Company  to the  public  without
registration, the Company agrees to use its best efforts to:

                  (a) Make and keep public information available, as those terms
are understood  and defined in Rule 144, at all times  subsequent to ninety (90)
days after the effective date of the first  registration  statement  covering an
underwritten  public  offering  filed by the  Company,  or if such  registration
statement has already been filed, as of the date hereof;

                  (b) File with the  Commission  in a timely  manner all reports
and other  documents  required of the Company  under the Act and the  Securities
Exchange Act of 1934, as amended (the "1934 Act"); and

                  (c)  Furnish to any Holder so long as such  Holder owns any of
the  Registrable  Securities  forthwith upon request a written  statement by the
Company that it has complied with the reporting requirements of Rule 144 (at any
time after ninety (90) days after the effective date of said first  registration
statement filed by the Company,  or if such  registration  statement has already
been filed, as of the date hereof), and of the Act and the 1934 Act (at any time
after it has become  subject to such reporting  requirements,  or, if already so
subject,  as of the date hereof),  a copy of the most recent annual or quarterly
report of the  Company,  and such other  reports and  documents  so filed by the
Company as may be  reasonably  requested  in availing  any Holder of any rule or
regulation of the Commission  permitting  selling of any such securities without
registration.

         1.10 Proposed Transfers of Registrable  Securities.  The Holder of each
certificate representing Registrable Securities,  by accepting those securities,
agrees to comply in all respects with the following provisions:

                  (a)  Prior  to  any  proposed   transfer  of  any  Registrable
Securities  (other than under the  circumstances  described  in  Paragraph  1.2,
above), the Holder of those Registrable Securities shall given written notice to
the Company of such Holder's intention to effect the transfer.

                                       5

<PAGE>

                  (b)  Each  such   notice   shall   describe   the  manner  and
circumstances of the proposed transfer, shall be accompanied by such information
as is  necessary in order to  establish  that such  transfer may be made without
registration  under  the Act  and,  other  than in  connection  with a  proposed
transfer in according  with Rule 144 or any similar rule or regulation  that may
hereafter be enacted by the Commission permitting a Holder to sell securities to
the public without  registration  on terms and conditions  analogous to those of
Rule 144,  and except with  respect to  transactions  not  involving a change in
beneficial   ownership  or  transactions   involving  the  distribution  without
consideration  of  Registrable  Securities by any of the Holders to any of their
partners, retired partners, or any estate of their partners or retired partners,
or to any  affiliated  venture  capital  partnership  or to any  members  of the
immediate  family of the Holders or to a family trust of the  Holders,  shall be
accompanied  by  either  (i) a written  opinion  of legal  counsel  who shall be
reasonably satisfactory to the Company and its counsel stating that the proposed
transfer of the  Registrable  Securities  may be effected  without  registration
under the Act and without  qualification;  or (ii) a Ano action" letter from the
SEC;  or  (iii) an  appropriate  registration  statement  with  respect  to such
Registrable  Securities  filed by the Company with the  Commission  and declared
effective by the Commission.

                  (c) Having  satisfied  paragraph  1.10(b) above, the Holder of
such  Registrable  Securities  shall be  entitled to  transfer  the  Registrable
Securities in accordance with the terms of the notice delivered by the Holder to
the Company.

                  (d) Each  certificate  evidencing the  Registrable  Securities
transferred shall bear the appropriate  restrictive  legends as set forth on the
Registrable  Securities  themselves  prior to  transfer.  But the Company  shall
remove such restrictive legend upon the request of the Holder if (i) the Company
has received an opinion of counsel who is  reasonably  acceptable  to it and its
counsel to the effect that  registration of any and all future  transfers is not
required;  and (ii) an appropriate  registration  statement with respect to such
Registrable  Securities  has been filed by the Company with the  Commission  and
declared  effective by the  Commission;  or (iii) such transfer shall be made in
compliance with the requirements of Rule 144 or its successor.  In these events,
the Company shall cause new certificates  without the said restrictive legend to
be  issued  promptly  to  the  Holder  in  exchange  for  outstanding   legended
certificates,  and such  unlegended  securities  shall no longer be  Registrable
Securities under this Agreement.

         1.11 Transfer of Registration  Rights.  The registration  rights of the
Holders under this  Agreement may be  transferred to any transferee who acquires
Registrable Securities; provided, however, that such transfer of rights shall be
effective  only where the Company is given written  notice by the Holder stating
the names and address of the transferee  and  identifying  the  securities  with
respect to which the rights under this Agreement are being assigned.
