ITEM 1.  BUSINESS

A.    General Development of Business

      Noise Cancellation  Technologies,  Inc. ("NCT" or the "Company")  designs,
develops,  licenses, produces and distributes electronic systems for Active Wave
Management including systems that electronically reduce noise and vibration. The
Company's  systems are  designed for  integration  into a wide range of products
serving major markets in the transportation, manufacturing, commercial, consumer
products  and  communications  industries.  The  Company  has  begun  commercial
application  of its  technology  through  a number  of  product  lines,  with 70
products currently being sold, including NoiseBuster(R)  communications headsets
and NoiseBuster  Extreme!(TM) consumer headsets,  Gekko(TM) flat speakers,  flat
panel transducers ("FPT(TM)"), ClearSpeech(TM),  microphones, speakers and other
products,   adaptive  speech  filters  ("ASF"),   the   ProActive(TM)   line  of
industrial/commercial  active  noise  reduction  ("ANR")  headsets,  an aviation
headset for  pilots,  an  industrial  muffler or  "silencer"  for use with large
vacuums and blowers,  quieting  headsets  for patient use in magnetic  resonance
imaging ("MRI") machines, and an aircraft cabin quieting system.

   In early 1998,  the Company  introduced  the GekkoTM  flat  speakers  and the
ClearSpeechTM  corporate  intranet  telephone software (the "I-Phone") which the
Company  believes  will have wide  application  in the audio and  communications
industries.  As part of its product line expansion  plans,  the Company plans to
introduce over 25 new products and associated  accessories  during the first six
months of 1998.

   In keeping with the  direction  established  in late 1994,  during 1997 the
Company continued the practice of marketing its technology  through licensing to
third  parties  for fees and  subsequent  royalties.  During  1997,  the Company
entered into ten new technology license agreements. See G. "Strategic Alliances"
and Note 3 - "Notes to Consolidated Financial Statements."

   In late 1995 the Company  redefined its corporate mission to be the worldwide
leader  in the  advancement  and  commercialization  of Active  Wave  Management
technology.   Active  Wave  Management  is  the  electronic   and/or  mechanical
manipulation of sound or signal waves to reduce noise,  improve  signal-to-noise
ratio and/or enhance sound quality.

   As  distribution  channels are  established  and as product  sales and market
acceptance  and  awareness  of the  commercial  applications  of  the  Company's
technologies  build,  revenues from  technology  licensing  fees,  royalties and
product  sales  are  forecasted  to fund an  increasing  share of the  Company's
requirements.  The revenues  from these  sources,  if realized,  will reduce the
Company's dependence on engineering and development  revenues.  This progression
is reflected in the revenue  percentages  discussed briefly below and more fully
in Item 7.  "Management's  Discussion  and Analysis of Financial  Condition  and
Results of Operations."

   From the Company's inception through December 31, 1997,  approximately 23% of
its  operating  revenues  have  come  from the sale of  products  and 31% of its
operating revenues have come from licensing of the Company's  technology,  while
approximately  46% of its  operating  revenues  have come from  engineering  and
development services.

   Active noise control offers many advantages over traditional  passive methods
of noise control such as  conventional  mufflers,  ear protectors and acoustical
padding.  Active noise control systems: (i) generally reduce only unwanted noise
and permit  desired  sounds such as the human voice,  music or warning  tones to
pass freely,  (ii) are more successful in attenuating low frequency noise, (iii)
contribute  to energy  savings and provide  other  economic  benefits in various
applications, and (iv) generally are smaller and lighter.

   Active Wave Management is the utilization of active noise control  technology
and certain other  technologies  which results in the  electronic and mechanical
manipulation of sound or signal waves to reduce noise,  improve  signal-to-noise
ratio and/or enhance sound quality.

   NCT believes  that it has a  significant  position in Active Wave  Management
technology, holding 256 patents and an extensive portfolio of know-how and other
unpatented technology.

     The Company has entered  into a number of strategic  supply,  manufacturing
and marketing  alliances  with leading  global  companies to  commercialize  its
technology. These strategic alliances historically have funded a majority of the
Company's  research and  development,  and  provided  the Company with  reliable
sources  of  components,  manufacturing  expertise  and  capacity,  as  well  as
extensive   marketing  and   distribution   capabilities.   NCT  has  continuing
relationships  with  Walker  Manufacturing  Company  ("Walker")  (a  division of
Tennessee Gas Pipeline Company, a wholly owned subsidiary of Tenneco,  Inc.), AB
Electrolux ("Electrolux"),  Analog Devices, Inc. ("ADI"), Ultra Electronics Ltd.
("Ultra"),  The  Charles  Stark  Draper  Laboratory,  Inc.  ("Draper"),  Applied
Acoustic Research,  L.L.C.  ("AAR"),  Hoover Universal,  Inc. ("Hoover") and New
Transducers,  Ltd.  ("NXT"),  among others,  in order to penetrate major markets
more  rapidly  and  efficiently,  while  minimizing  the  Company's  own capital
expenditures.

   In March 1995,  the Company and Ultra  amended  their  teaming  agreement and
concluded  a  licensing  and  royalty  agreement  for $2.6  million and a future
royalty of 1 1/2% of sales commencing in 1998.

   On November  15,  1995,  the Company and Walker  executed a series of related
agreements (the "Restructuring  Agreements")  regarding the Company's commitment
to help fund $4.0  million of product and  technology  development  work and the
transfer of the  Company's  50%  interest in WNCT to Walker.  The  Restructuring
Agreements  provided  for the  transfer  of the  Company's  interest in WNCT (an
equally  owned  partnership  between  Walker and the  Company)  to  Walker,  the
elimination  of  the  Company's  previously  expensed  obligation  to  fund  the
remaining $2.4 million of product and technology  development work, the transfer
to Walker of certain  Company owned  tangible  assets related to the business of
WNCT, the expansion of certain  existing  technology  licenses and the Company's
performance  of  certain  research  and  development  activities  for  Walker at
Walker's expense as to future activities.

   An important factor for the Company's  continuing  development is its ability
to recruit and retain key personnel.  As of February 28, 1998 the Company had 85
employees,  including 47 engineers and technical  staff.  Among its  engineering
staff and  consultants  are several  scientists  and inventors  that the Company
believes  are  preeminent  in the  active  noise  and  vibration  control  field
worldwide.

   The Company was  incorporated  in Nevada on May 24, 1983. In April 1985,  the
Company  moved its  corporate  domicile to Florida and assumed its present name,
and in January 1987,  following the  assumption of control of the Company by the
present  management,  it changed its state of incorporation  to Delaware.  NCT's
executive offices, research and product development facility are located at 1025
West Nursery Road, Suite 120, Linthicum,  Maryland 21090; telephone number (410)
636-8700. NCT maintains sales and marketing offices at 1 Dock Street, Suite 300,
Stamford,  Connecticut  06902;  telephone  number (203) 961-0500.  The Company's
European  operations are conducted through its product development and marketing
facility in  Cambridge,  England.  NCT also  maintains  a marketing  facility in
Tokyo, Japan.

B.    Business Strategy

   The Company  revised its strategy and redefined  its mission  during 1994 and
1995,  expanding its  technology  development  into areas outside of traditional
active noise and vibration  control in order to address  markets  having greater
opportunities  such as  communications  and audio.  The  acquisition  of certain
assets  and all of the  intellectual  property  of Active  Noise  and  Vibration
Technologies,  Inc. ("ANVT")  broadened the Company's  portfolio of intellectual
property  and removed  restrictions  on the Company  regarding  licensing of the
Chaplin Patents (see C. "Technology") to unaffiliated third parties. The Company
can now license the Chaplin  Patents  directly to  unaffiliated  third  parties,
which provides the Company with a greater ability to earn  technology  licensing
fees and royalties from such patents. Thus, while the Company continues to focus
on products  which the Company  believes will generate near term revenue,  it is
increasing its emphasis on technology licensing fees and royalties. Further, the
Company is working  continuously  to lower the cost of its  products and improve
their technological performance.

C.    Technology

   Active  noise  attenuation  is not a new idea.  Creating a mirror image of an
unwanted noise or sound wave and using it to cancel or reduce the original sound
wave dates  back to the early part of this  century.  The first  systems  used a
simple "delay and invert" approach and showed some promise,  but the prohibitive
cost of computing power and the inadequacy of acoustics and related technologies
limited their effectiveness.

   In the mid-1970's,  a major  breakthrough  took place with the application of
adaptive  filters  to  generate  anti-noise.   These  filters  allowed  for  the
development of active control systems that could  continuously  adapt to changes
in noise output both in the external world and from control components. A second
breakthrough  in the  mid-1970's  was  made  by  Professor  G.B.B.  Chaplin.  He
recognized that many noise sources,  particularly  machines,  exhibit "tonal" or
repetitive  noise.   Chaplin  further  recognized  that  the  predictability  of
repetitive  noise  allows for  creation  of an accurate  anti-noise  signal and,
therefore, more effective cancellation or attenuation.

   Practical  application  of this  technology  was  still not  possible  as the
electronic  technology available at the time was insufficient for implementation
of active noise reduction systems.  Since that time, digital computer technology
has evolved to the point where cost-effective microprocessors,  known as digital
signal processors ("DSP") can perform the complex calculations involved in noise
cancellation  and  reduction.  This advance has made it feasible to apply active
noise reduction to previously  unsolveable  problems in low frequency noise at a
reasonable cost.

  Active Noise  Reduction.  Active  noise  reduction  systems are  particularly
effective at reducing low frequency noise. As opposed to a passive noise control
system  that is  designed  to mask a  noise,  active  noise  control  removes  a
significant  portion of the noise energy from the  environment by creating sound
waves that are equal in frequency but opposite in phase. The illustration  below
shows the relationship, in time, of a noise signal, an anti-noise signal and the
residual noise that results when they meet.
                          ACTIVE NOISE REDUCTION


                            [Graphic Omitted]


   Active Wave  Management.  Active Wave Management is the combination of active
noise reduction  technology and certain other  technologies which results in the
electronic  and/or  mechanical  manipulation  of sound or signal waves to reduce
noise, improve signal-to-noise ratio and/or enhance sound quality.

   Signal  Enhancement.  Active Wave  Management  technology also can be used to
attenuate  unwanted  signals that enter into a communications  network,  as when
background  noise enters  telecommunications  or radio  systems from a telephone
receiver, or microphone. The Company has developed patented technology that will
attenuate the background  noise  "in-wire",  so that the signals  carried by the
communications  network include less of the unwanted noise, allowing the speaker
to be heard more clearly over the network.  An application of this technology is
in-wire  attenuation  of siren noise over two-way radio  communications  between
emergency vehicles and dispatchers at hospitals and police or fire stations.

   Silicon Micromachined  Microphone (SMM). In 1994, NCT purchased the exclusive
rights to manufacture and commercialize a silicon micromachined  microphone as a
technically  superior and less  expensive  alternative  to  currently  available
electret microphones. The SMM has potential applications not only in the audible
range of frequencies, but in the ultrasonic range as well.

   Adaptive Speech Filter ("ASF").  The adaptive speech filter algorithm removes
noise from voice  transmissions.  ASF  parameters  can be  adjusted  to optimize
performance  for a particular  noise,  or can be set to provide noise  reduction
across  a wide  range  of  noises.  ASF  applications  include  teleconferencing
systems,   cellular  telephones  and  "airphones",   telephone  switches,   echo
cancellers, and communications systems in which background noise is predominant.
ASF is currently  available  for use on three  hardware  platforms.  The Company
added an echo cancellation algorithm to its Windows-based ACM version of ASF and
has begun testing.

   NCT Audio. The Company has expanded its flat panel  transducer  technology to
include audio systems for the  reproduction of speech and music.  The Company is
developing Top Down Surround  SoundTM  ("TDSS") for the automobile audio market,
in both original equipment manufacturer ("OEM") and after-market versions.  TDSS
employs  FPT(TM)  to  produce  sound  much  closer  to the  listener's  ear than
conventional speakers. This placement and revolutionary  technology allows for a
"sweet space" listening experience as opposed to a conventional speaker system's
"sweet spot"  listening  experience.  The Company has also  developed flat audio
speaker products utilizing FPT(TM) technology for commercial and consumer use.

D.    NCT Proprietary Rights and Protection

   NCT holds a large number of patents and patent  applications.  The  Company's
intellectual  property  strategy  has  been  to  build  upon  its  base  of core
technology  patents  with  newer  advanced   technology  patents  developed  by,
purchased by or  exclusively  licensed to the Company.  In many  instances,  the
Company  has  incorporated  the  technology  embodied in its core  patents  into
patents covering specific product  applications,  including the products' design
and  packaging.  The Company  believes  this  building-block  approach  provides
greater  protection  to the Company  than relying  solely on the  original  core
patents. As its patent holdings increase, the Company believes the importance of
its core patents will diminish from a competitive viewpoint.

   During 1994 the Company  purchased certain assets of ANVT, which included all
of ANVT's  intellectual  property rights.  Among the ANVT intellectual  property
rights were ANVT's interest in the 10 basic Chaplin Patents which are now solely
owned by NCT as the sole shareholder of CPH. These patents cover inventions made
by  Professor  G.B.B.  Chaplin in the late 1970s and early  1980s (some of which
have now expired).

   The  Chaplin  Patents  form only one group of core  patents  upon which NCT's
technology is based. In March 1990, the Company acquired exclusive  ownership of
10 patents  developed  under the auspices of the National  Research  Development
Corporation ("NRDC"), an organization sponsored by the British Government. Among
other things, the NRDC Patents,  of which the Swinbanks and Ross patents are the
most  important,  utilize the  adaptive  feed  forward  approach to active noise
control.  The  Swinbanks  patent  covers an  improved  method of  analyzing  the
incoming  noise or vibration  through the use of a "frequency  domain"  adaptive
filter  which  splits the  incoming  noise into  different  frequency  bands for
analysis and  recombines the data to generate the  anti-noise  signal.  The Ross
patent  covers  the use of a "time  domain"  filter  which  uses input and error
signals to enhance a system's  ability to compensate for feedback from actuators
to sensors.  Without this filter, the system will detect and begin canceling its
own self-generated anti-noise.

   The  Company  has built  upon these core  patents  with a number of  advanced
patents and patent  applications.  These include the Digital  Virtual  Earth(TM)
patent,  which covers digital  feedback  control,  and patents on  multi-channel
noise control.  The Company has also applied for patents on combined feedforward
and  feedback  control,  control  using  harmonic  filters,  filters  for signal
enhancement and speech filtering, control systems for noise shaping and others.

   As part of the purchase of certain ANVT assets,  the Company acquired all the
rights to nine inventions  previously  belonging to the Topexpress  Group in the
United Kingdom. The international patent coverage of these inventions varies but
eight have been granted  patent  protection  with numerous  counterpart  foreign
applications still pending.  Among the other intellectual property acquired from
ANVT are  patents  relating  to  active  auto  mufflers  and  noise  suppression
headrests,  several patent applications on advanced algorithms, and active noise
headsets,  many related  disclosures  and various  disclosures in other areas of
active  attenuation of noise and vibration.  Additionally,  the Company acquired
the rights to three basic inventions known as the Warnaka Patents.

   In 1994,  the  Company  obtained a license  for the  exclusive  rights to the
silicon  micromachined  microphone  technology developed by Draper in Cambridge,
Massachusetts.  At this time, two patents  describing the basic  technology have
been issued and one is pending.

   In 1995 the Company  acquired  several U.S. patents dealing with ASF which is
used in the Company's Clear Speech(TM) product line.

     In 1996 and 1997 the  Company  was  granted 90 new  patents in the field of
Active Wave Management.

   The Company  holds or has rights to 256  inventions  as of December 31, 1997,
including 96 United States patents and over 245  corresponding  foreign patents.
The Company has pending 177 US and foreign patent applications.  NCT's engineers
have made 122 invention  disclosures  for which the Company is in the process of
preparing  patent  applications.  The  Company's  presently  owned  patents have
expiration  dates which will occur  during the years 1998  through 2015 with the
majority occurring during or after 2009.

   No assurance can be given as to the range or degree of protection  any patent
issued to, or  licensed  by, the  Company  will  afford or that such  patents or
licenses  will  provide  protection  that has  commercial  significance  or will
provide competitive  advantages for the Company's products.  No assurance can be
given that the  Company's  owned or  licensed  patents  will  afford  protection
against  competitors  with  similar  technology,  or that others will not obtain
patents  claiming  aspects  similar to those covered by the  Company's  owned or
licensed patents or patent applications.  No assurance exists that the Company's
owned or licensed patents will not be challenged by third parties,  invalidated,
rendered  unenforceable  or  designed  around.  Furthermore,  there  can  be  no
assurance  that any pending patent  applications  or  applications  filed in the
future will result in the issuance of a patent. The invalidation, abandonment or
expiration  of patents  owned or licensed  by the  Company  and  believed by the
Company to be commercially significant could permit increased competition,  with
potential adverse effects on the Company and its business prospects.

   Annuities and maintenance  fees for the Company's  extensive patent portfolio
are a significant portion of the Company's annual expenses.  If, for the reasons
described in Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations -- "Liquidity and Capital Resources" below, it becomes
necessary  for the Company to reduce its level of  operations,  the Company will
not be able to continue to meet the extensive  monetary outlay for annuities and
maintenance  fees to  keep  all  the  patents  and  applications  from  becoming
abandoned and will have to prioritize its portfolio accordingly.

   The Company has conducted only limited patent  searches and no assurances can
be given  that  patents  do not exist or will not be issued in the  future  that
would have an adverse effect on the Company's  ability to market its products or
maintain its  competitive  position  with respect to its  products.  Substantial
resources  may be  required  to obtain  and defend  patent  and other  rights to
protect present and future technology and other property of the Company.

   The Company has been granted the following trademarks:

         Mark               Field of Use

  No  assurance  can be  given as to the  range or  degree  of  protection  any
trademark  issued to, or  licensed  by,  the  Company  will  afford or that such
trademarks or licenses will provide protection that has commercial  significance
or will provide competitive  advantages for the Company's products. No assurance
can be given  that  the  Company's  owned or  licensed  trademarks  will  afford
protection against competitors with similar products or trademarks. No assurance
exists that the Company's owned or licensed trademarks will not be challenged by
third parties, invalidated, or rendered unenforceable. Furthermore, there can be
no assurance that any pending  trademark  applications or applications  filed in
the  future  will  result in the  issuance  of a  trademark.  The  invalidation,
abandonment  or expiration  of  trademarks  owned or licensed by the Company and
believed by the Company to be commercially  significant  could permit  increased
competition,  with  potential  adverse  effects on the Company and its  business
prospects.

   The Company has conducted only limited  trademark  searches and no assurances
can be given  that  trademarks  do not exist or will not be issued in the future
that  would  have an  adverse  effect on the  Company's  ability  to market  its
products or maintain its  competitive  position  with  respect to its  products.
Substantial  resources may be required to obtain and defend  trademark rights of
the Company.

   The Company's policy is to enter into confidentiality  agreements with all of
its executive officers,  key technical personnel and advisors, but no assurances
can be made that Company  know-how,  inventions  and other secret or unprotected
intellectual property will not be disclosed to third parties by such persons.


E.    Existing Products

      NCT Hearing Products

   MRI  Headphones.  Since 1991,  the Company has been  producing  active  noise
reduction  headsets for use by patients  undergoing  MRI  procedures.  NCT's MRI
headphone   reduces  the  noise   generated  by  the   gradient   coils  of  the
superconducting MRI magnet. This noise is known to be disturbing to patients and
is a factor in a  patient's  ability to tolerate  the  scanning  procedure.  The
Company's  product is an  implementation  of a patented  technology owned by NCT
which  permits the  delivery  of  anti-noise  signals and music  directly to the
patient  while the patient is in the bore of the MRI scanner.  While  undergoing
the MRI  examination,  a patient can be communicated  with by the doctor or scan
operator through NCT's system.  The Company is a supplier to Siemens,  a leading
manufacturer of MRI machines in the U.S.

   NoiseBuster   Extreme!(TM).   NCT  is  currently  marketing  its  NoiseBuster
Extreme!(TM)  personal  active  noise  reduction  headphone  for  consumers at a
suggested  retail  price  of $69.  This  active  headphone  selectively  reduces
unwanted  noise  generated  by aircraft  engines,  lawnmowers,  street  traffic,
household  appliances and other  annoying noise sources,  permitting the user to
hear desired sounds, such as human  conversation,  warning signals or music. The
NoiseBuster  Extreme!(TM) is a lightweight,  portable headphone wired to a small
controller  that can be clipped to the user's  clothing or belt.  The controller
pack accepts two AAA batteries for a minimum of 100 hours continuous  operation.
The  NoiseBuster  Extreme!(TM)  contains a port where the  consumer  can plug in
personal  audio  devices such as a radio,  tape player or compact disc player so
the user can enjoy music while in a noisy setting.  The product can also be used
with an aircraft's in-flight entertainment system.

   The Company is marketing  the  NoiseBuster  Extreme!TM  through  distribution
channels, including electronics retail stores, specialty catalogues and directly
through a toll-free  "800"  number.  Initial  product  shipments of the original
NoiseBuster(R) were made in September 1993. Product shipments of the NoiseBuster
Extreme!(TM) began during the first quarter of 1997.

   The NoiseBuster Extreme!(TM) line is being expanded to include communications
headsets for cellular,  multimedia and telephony. The products will be the first
ANR offerings for these applications and will improve speech  intelligibility in
the presence of background noise.
Product shipments began during the first quarter of 1998.

   NB-AVC.  In August 1994, the Company began shipping an active noise reduction
communications  headset  specifically  designed for use by  commercial  aviation
pilots. The product is FAA-TSO certified and sold by Telex as the Airman ANR. At
6.9 oz,  one-third  the weight of other active  noise  reduction  headsets,  the
Airman  ANR  is the  first  ultra-lightweight,  open-back  headset  of its  kind
developed for the general aviation market.  A  high-performance  noise canceling
electret microphone is connected to a flexible boom. The controller pack accepts
four AA batteries for a minimum of 40 hours continuous operations and includes a
belt clip.

   ProActive(TM)  1000/1500.  In March 1995,  the  Company  began  shipping  its
ProActive(TM)  1000 headphones and ProActive(TM) 1500  communications  headsets.
These products are lightweight, open-back in style and can provide up to 20dB of
active noise reduction between  30-1200Hz.  When used in work settings dominated
by  low-frequency  noise,  these products  improve  comfort,  reduce fatigue and
improve  concentration  and  productivity  for  the  user.  In the  case  of the
ProActive(TM) 1500 two-way and mobile  communications  version,  the clarity and
intelligibility  of  communications  is  improved  when the  masking  effect  of
background noise is reduced.  These products are powered by a rechargeable NICAD
battery  designed  for use during a 12-hour  work day.  The battery  fits into a
small,  lightweight belt-pack that can be clipped onto the belt. The battery can
be recharged  overnight using NCT's personal  charger which is included with the
product.

   ProActive(TM)  3000/3500. In August 1995, the Company expanded its industrial
headset product line to include the  ProActive(TM)  3000 series.  These products
combine active noise reduction of low-frequency noise with a closed-back passive
ear muff,  appropriate for general  industrial use. This is the first product of
its kind in which the active  electronics  as well as the power source have been
totally  integrated  into the  earmuff,  providing  the user with  mobility  and
safety. The electronics are powered by a NICAD rechargeable battery specifically
designed  for use  during a  12-hour  work day.  The  battery  can be  recharged
overnight using NCT's personal charger.  The  ProActive(TM)  3000 active earmuff
and  ProActive(TM)  3500  active  communications  earmuff  address  the  hearing
protection requirements of a variety of industries.

   ProActive(TM)   3100/3600.   In  December  1995,  the  Company   announced  a
behind-the-head  version of its ProActive(TM)  3000 line for use with hard hats.
This is the first  implementation  of active noise reduction  earmuffs in a hard
hat  style  and will  address  the  needs of  industries  such as  construction,
utilities  and  others  requiring  both  hearing  protection  and hard  hats for
workers. Product shipments commenced in the second quarter of 1996.

   NB-PCU.  The Company is working with a leading  manufacturer  and supplier of
aircraft  cabin  products  on the  integration  of NCT's  active  noise  control
technology into in-flight passenger entertainment systems. As a component of the
system, NCT has also developed a low-cost headset specifically for in-flight use
to be used in conjunction  with the  integrated  electronics.  NCT's  technology
electronically  reduces  aircraft engine noise while enhancing the audibility of
desired sounds like speech, music and warning signals. Lowering the engine drone
can help alleviate the anxiety and fatigue often  associated with flying.  While
the  system  is in use,  passengers  inside  an  aircraft  cabin  can  carry  on
conversations at a comfortable  level or hear in-flight movies and music without
over  amplification  and distortion.  Installation of this product in commercial
airliners commenced during the fourth quarter of 1997.


      NCT Communications

   Adaptive Speech Filter ("ASF").  ASF removes  background noise from voice and
data  transmission  and  recognition.  Available in real-time  double  precision
fixed-point  DSP,  floating-point  DSP,  and  Windows  95/Windows  NT ACM driver
versions,  ASF can be used as a  pre-processor  for voice  and data  compression
algorithms,  and also  contributes  to  improved  voice  and  data  recognition.
Additional  uses  include  teleconferencing  systems,  cellular  and  airphones,
telephone  switches,   echo  cancellers  and  communications  systems  in  which
background noise is predominant.

      ClearSpeech(TM).  NCT has introduced its  ClearSpeech(TM)  line of digital
communications   accessories.   These  products  employ  the  NCT  patented  ASF
technology  to cancel  background  noise from  either  transmitted  or  received
speech.  These  products can be used with  hands-free  cellular  phone  cradles,
two-way  radios,  AM/FM  radios,  SMR  networks and speaker  phones.  Users will
benefit from clearer, more intelligible conversations,  free of background noise
and other transmission interference.

   Gekko(TM)  Flat  Speaker.  In  January,  1998,  the  Company  introduced  the
Gekko(TM) Flat Speaker  product line for home theater and home audio.  Gekko(TM)
Flat Speakers  feature the Company's  FPT(TM)  patented audio  technology  which
evenly disperses  high-quality sound and a unique, slim design for wall mounting
as picture frames with quality artwork.  The Gekko(TM) Flat Speaker received the
Best of Showcase Honoree award in the home theater category from Innovations '98
at the 1998  International  Winter  Consumer  Electronics  Show in Las  Vegas in
January,  1998. Initial product shipments are expected to commence in the second
quarter 1998.

F.  Products Under Development

     NCT Hearing Products

   Advanced  Digital  Electronic  Headsets.  NCT is working to develop  advanced
headset models using its proprietary  digital  technology.  Management  believes
that there is a broad market for specialty  industrial headsets that will permit
factory and assembly  workers to operate close to loud  machinery in the marine,
steel, textile, paper, construction,  road building and metalworking industries,
among others.  Conventional ear muffs and protectors are not as effective as the
Company's  active  headsets,  which can selectively  block machinery noise while
allowing  the  worker to listen to  ordinary  human  communications  and,  where
appropriate,  to hear warning signals, tones or bells. The Company is working to
develop headset models that will operate on a lightweight,  rechargeable battery
pack, thus allowing the worker to move freely about the factory.

     NCT Communications

   ClearSpeech(TM)  Product Line.  There are several  additional  communications
products under  development.  Design  improvements are being made to the current
ClearSpeech(TM)  product line to improve  market  penetration.  NCT is exploring
relationships with chip manufacturers to develop custom integrated  circuits for
the ASF  technology  to reduce the cost of the  ClearSpeech(TM)  product line as
well as for use as a new product.

     NCT Microphones

   Silicon Micromachined  Microphone ("SMM"). In 1994, NCT obtained a license to
the exclusive  rights to manufacture and  commercialize a silicon  micromachined
microphone.  A  small,  compact,  surface-mountable  silicon  actuator,  the SMM
provides customers with improved and adjustable  sensitivity,  a low noise floor
and resistance to environmental  extremes.  The ability to integrate  additional
circuitry on the SMM chip has also proven  attractive  to potential  users.  The
SMM's low noise floor and adjustable  sensitivity  improve voice  recognition in
high  ambient  noise  environments.  NCT is working  with voice  processing  and
computer  hardware  companies to utilize the SMM to enhance the  performance  of
their systems.  In the first quarter of 1996, NCT released initial prototypes of
the  devices.   In  December,   1997,   the  Company   announced   that  Siemens
Semiconductors  of  Siemens  AG  ("Siemens")  had  licensed  the  Company's  SMM
technology  and that  Siemens  would  develop,  manufacture  and market the SMM.
Samples  are  expected  to be  available  in the fourth  quarter  1998.  Initial
production is scheduled to commence in the first quarter 1999.

     NCT Audio

   Top Down Surround Sound(TM).  TDSS is a novel automobile audio speaker system
developed  by the  Company.  Initial  demonstrations  and  listener  tests  have
indicated  a high  degree  of  enthusiasm  for  the  "sweet  space"  which  TDSS
generates.  The Company has established a joint venture,  OnActive, with AAR and
Hoover for the automobile audio speaker market.

     Small Fans

   Household  Appliances.  NCT has developed  fan quieting  systems for multiple
applications,  including a quiet  kitchen hood fan and a quiet  vacuum  cleaner.
NCT's active fan systems are designed with higher  efficiency than  conventional
fans and have  demonstrated  up to a 30%  reduction  in energy  usage.  The cost
sensitivity of the consumer  appliance  marketplace  has been a barrier to prior
introduction of this technology.  As a result of  relationships  NCT enjoys with
its component supply joint venture partners, the Company believes that the price
sensitivity issues of consumer product markets may be addressed in the near-term
as  miniaturization  of the  technology  continues  and the  unit  cost of NCT's
electronic  components  continues  to decline.  Management  believes  that NCT's
proprietary  technology  will be incorporated in a wide range of other products,
including air conditioners, dishwashers, clothes washers and dryers, hair dryers
and other types of fans.

     Panels and Enclosures

   Electric  Utility  Transformers.  Electric  power  distribution  by utilities
requires  the  use of  large  transformers,  often  placed  in  residential  and
commercial neighborhoods, which emit a low frequency "hum" that irritates people
living and working  nearby.  Utilities try to mask this noise by passive  means,
although  usually  not very  successfully.  The  Company  has  developed  active
enclosure and active panel systems which reduce the "hum" of  transformer  noise
by use of flat  actuators  that  cause the  enclosure  or panels to vibrate in a
manner to reduce the noise.  The Company can  install  its active  panel  system
directly to the metal sides or "skin" of an installed  transformer,  thus making
its systems available to retrofit markets as well as to OEMs. As an alternative,
an active enclosure can be built to house the transformer.

   In March 1995, the Company entered into an agreement with QuietPower Systems,
Inc., ("QSI") (see Item 13. "Certain Relationships and Related Transactions" and
Note 8 - "Notes to the Consolidated Financial Statements") by which QSI received
the  exclusive  rights  to  market,  sell and  distribute  transformer  quieting
products and gas turbine quieting  products in the utility  industry.  Under the
agreement QSI funds development of the systems. The agreement generally provides
that the Company manufactures the products and receives a royalty of 6% from QSI
on the sales of the products.

G. Strategic Alliances

   The Company's  transition  from a concern  primarily  engaged in research and
development  to one engaged in the licensing  production,  marketing and sale of
Active Wave Management  systems has been  facilitated by the  establishment  and
maintenance  of  strategic  alliances  with  major  domestic  and  international
business  concerns.  In exchange for the benefits to such concerns' own products
offered by the Company's  technology,  these  alliances under the terms of their
joint  venture  agreements  or  licenses  provide  marketing,  distribution  and
manufacturing  capabilities for the Company's products and enable the Company to
limit the expense of its own research and  development  activities.  In order to
ensure  dependable  sources of supply and to maintain  quality  control and cost
effectiveness  for  components  and  integrated  circuits  incorporated  in  the
Company's  systems,  an important element of the Company's  strategy has been to
identify and enter into alliances with  integrated  circuit  manufacturers  that
will develop and produce  custom-made  chips for NCT product  applications,  and
with  manufacturers of components that will supply and integrate  components for
NCT systems. The following is a summary of the Company's key alliances:

wide variety of applications within the acoustic and communications fields.

      Applied Acoustic Research, L.L.C, (U.S.)

   In December, 1995, NCT and AAR of State College,  Pennsylvania formed a joint
venture, OnActive Technologies,  L.L.C. ("OAT"), to commercialize advanced audio
applications, such as FPTTM and TDSS, into total audio systems and solutions for
the ground based vehicle market. Both partners, who initially owned equal shares
of the joint venture,  have licensed their  proprietary  technology to the joint
venture.

   In May, 1996,  Hoover  Universal,  Inc., a wholly owned subsidiary of Johnson
Controls,  Inc.  ("JCI")  acquired a 15% equity interest in OAT for $1.5 million
and acquired  rights to certain of the Company's and AAR's related patents for a
total of $1.5  million,  half of which was paid to the Company and half of which
was paid to AAR.

      New Transducers Ltd (UK).

   New  Transducers  Ltd.(NXT),  a wholly owned  subsidiary  of Verity Group PLC
("Verity")  and the Company  executed a cross  licensing  agreement  (the "Cross
License")  on March 28,  1997.  Under  terms of the Cross  License,  the Company
licensed  patents and patents pending which relate to FPT technology to NXT, and
NXT licensed patents and patents pending which relate to parallel  technology to
the Company. In consideration of the license, during the first quarter 1997, NCT
recorded  a $3.0  million  license  fee from NXT and the  Company  will  receive
royalties  on future NXT  licensing  and  product  revenue.  On April 15,  1997,
Verity, NXT and the Company executed several agreements and other documents (the
"New Agreements")  terminating the Cross License, and certain related agreements
and replacing them with a new cross license (the "New Cross  License"),  and new
related agreements. The material changes effected by the New Agreements included
the inclusion of Verity as a party along with its wholly owned  subsidiary  NXT;
providing  that the license fee payable to NCT could be paid in ordinary  shares
of Verity  stock.  The  subject  license fee was paid to the Company in ordinary
shares of Verity stock which were subsequently sold by the Company. On September
27, 1997,  Verity,  NXT, NCT Audio Products,  Inc. ("NCT Audio") and the Company
executed  several  agreements  and other  documents,  terminating  the New Cross
License  and a related  security  deed and  replacing  them with new  agreements
(respectively,  the "Cross License  Agreement  dated September 27, 1997" and the
"Master License  Agreement").  The material  changes effected by the most recent
agreements  included  an  expansion  of  the  fields  of use  applicable  to the
exclusive  licenses  granted to Verity and NXT and an increase in the  royalties
payable on future licensing and product revenues.

      Oki Electronic Industry Co., Ltd. (`Oki")

   In October, 1997, the Company and Oki executed a license agreement. Under the
terms of the  agreement  which  included an up-front  license fee and future per

cancellation  and echo  cancellation  algorithms for use with VLSI's current and
future  integrated  circuits  targeted  to the  digital  cellular  and PCS phone
market, as well as emerging computer telephony  markets.  The noise cancellation
algorithm is specifically  designed to remove  background  noise from speech and
other  transmitted  signals,  greatly improving  intelligibility  and clarity of
communications.  The echo  cancellation  algorithm  cancels  acoustical echo for
hands-free telephony operations including cellular and speaker phones.

H.    Marketing and Sales

   In addition to marketing its Active Wave  Management  technology  and systems
through its strategic  alliances as described above, the Company has an internal
sales and  marketing  force of  seventeen  people,  its  executive  officers and
directors,  and eight independent sales  representatives.  The independent sales
representatives may earn commissions of generally up to 6% of revenues generated
from sales of NCT products to customers  introduced to NCT by them, and up to 5%
of research and development funding revenues provided by such customers.  During
1997 and through  February  1998,  the Company  expanded its internal  sales and
marketing force by nine, from eight to seventeen professionals and will continue
to expand its internal sales force on a limited basis as the need dictates.

   Note  12 - "Notes  to the  Consolidated  Financial  Statements"  sets  forth
financial  information relating to foreign and domestic operations and sales for
the years ended December 31, 1997, 1996 and 1995.

   The Company does not have a significant  foreign  exchange  transaction  risk
because the majority of its non-U.S.  revenue is in U.S. dollars.  The remaining
revenue is in British pounds sterling and the Company's  underlying cost is also
in pounds sterling creating a natural foreign exchange protection.

I.    Concentrations of Credit Risk

   The  Company   sells  its  products   and  services  to  original   equipment
manufacturers,  distributors and end users in various industries  worldwide.  As
shown below, the Company's five largest  customers  accounted for  approximately
71% of revenues during 1997 and 59% of gross accounts receivable at December 31,
1997.  The Company  does not  require  collateral  or other  security to support
customer receivables.

     The Company regularly assesses the realizability of its accounts receivable
and  performs  a  detailed  analysis  of  its  aged  accounts  receivable.  When
quantifying the  realizability  of accounts  receivable,  the Company takes into
consideration  the value of past due receivables and the  collectibility of such
receivables, based on credit worthiness.

   Financial  instruments which potentially subject the Company to concentration
of  credit  risk  consist  principally  of cash and cash  equivalents  and trade
receivables.  The Company  considers all money market  accounts and  investments
with  original  maturities of three months or less at the time of purchase to be
cash  equivalents.  The Company primarily holds its cash and cash equivalents in
two banks and commercial  paper.  Deposits in excess of federally insured limits
were $12.4 million at December 31, 1997.

J.  Competition

   The Company is aware of a number of direct competitors in the field of Active
Wave Management.  Indirect competition also exists in the field of passive sound
and vibration attenuation. The Company's principal competitors in active control
systems include Andrea Electronics Corporation,  Bose Corporation,  Digisonix (a
division of Nelson  Industries,  Inc.),  Group Lotus PLC and Lotus Cars Limited,
Lord  Corporation,   Matsushita  Electric   Industrial  Co.,  Ltd.,   Sennheiser
Electronic Corp. and Sony  Corporation,  among others.  The Company's  principal
competitors in other fields of Active Wave Management  include IBM  Corporation,
Lucent Technologies, Inc. and Texas Instruments,  Incorporated. To the Company's
knowledge,  each of such  entities  is  pursuing  its own  technology  in active
control  systems,  either on its own or in  collaboration  with others,  and has
recently  commenced attempts to commercially  exploit such technology.  NCT also
believes that a number of other large companies,  such as the major domestic and
foreign communications,  computer,  automobile and appliance manufacturers,  and
aircraft  parts  suppliers  and  manufacturers,  have  research and  development
efforts  underway  in Active  Wave  Management  and active  noise and  vibration
control. Many of these companies, as well as the Company's potential competitors
in the passive sound and vibration  attenuation  field and other  entities which
could enter the active noise and vibration attenuation field and other fields of
Active Wave Management as the industry  develops,  are well established and have
substantially greater management,  technical,  financial,  marketing and product
development resources than the Company.

K.  Government Contracts

   The Company has acted as a government  subcontractor  in connection  with its
performance of certain engineering and development  services.  No such contracts
were in effect during 1997.  Government contracts provide for their cancellation
at  the  government's  sole  discretion,   in  which  event  the  contractor  or
subcontractor may recover its actual costs up to the date of cancellation,  plus
a specified profit percentage. Governmental expenditures for defense are subject
to the political process and to rapidly changing world events, either or both of
which may result in significant reductions in such expenditures in the proximate
future.  Government  contracts  are  not  viewed  as a  significant  part of the
Company's business.

L.  Research and Development

     Company-sponsored   research  and  development   expenses  aggregated  $6.2
million,  $7.0 million and $4.8 million for the fiscal years ended  December 31,
1997, 1996 and 1995, respectively.




M.  Environmental Regulation Compliance

   Compliance with Federal,  state and local provisions regulating the discharge
of materials into the  environment,  or otherwise  relating to the protection of
the   environment,   does  not  have  any  material   effect  upon  the  capital
expenditures, earnings or competitive position of the Company.

   Compliance by existing and  potential  customers of the Company with Federal,
state and local laws and  regulations  pertaining to maximum  permissible  noise
levels  occurring from the operation of machinery or equipment or the conduct of
other activities could be beneficial to sellers of noise reduction  products and
enhance demand for certain  applications of the Company's  technology as well as
products  developed or to be developed by the Company.  However,  at the present
time it is too  early  to  determine  what  quantitative  effect  such  laws and
regulations will have on the sale of the Company's products and technology.

N.  Employees

   The Company had 85 employees on February 28, 1998.  None of such employees is
represented  by a labor union.  The Company  considers  its  relationships  with
employees to be satisfactory.


ITEM 2.  PROPERTIES

   The  Company's  executive  office is located at the site of its  research and
technical   support   laboratory  in  Linthicum,   Maryland,   where  it  leases
approximately  40,000  square feet of space under  leases  which  expire in July
2000. The leases provide for current monthly rentals of  approximately  $35,000,
subject to annual inflationary adjustments

   The Company  maintains a sales and marketing office in Stamford,  Connecticut
where it leases  approximately  5,000  square  feet of space under a lease which
expires  in  December  2001  and  provides  for  a  current  monthly  rental  of
approximately $5,000.

   The Company's United Kingdom  operations are conducted in Cambridge,  England
where it leases 12,500 square feet of space under a lease which expires in March
1999, and provides for a current monthly rental of approximately $14,000.

ITEM 3.  LEGAL PROCEEDINGS

   On or about June 15, 1995,  Guido  Valerio  filed suit against the Company in
the  Tribunal  of Milan,  Milan,  Italy.  The suit  requests  the Court to award
judgment in favor of Mr.  Valerio as follows:  (i)  establish and declare that a
proposed independent sales representation  agreement submitted to Mr. Valerio by
the Company and signed by Mr.  Valerio but not  executed by the Company was made
and entered  into  between Mr.  Valerio and the Company on June 30,  1992;  (ii)
declare that the Company is guilty of breach of contract and that the  purported
agreement  was  terminated  by  unilateral  and  illegitimate  withdrawal by the
company;  (iii) order the Company to pay Mr. Valerio $30,000 for certain amounts
alleged to be owing to Mr. Valerio by the Company; (iv) order the Company to pay
commissions  to which Mr.  Valerio  would have been  entitled if the Company had
followed up on certain alleged  contacts made by Mr. Valerio for an amount to be
assessed by technicians and  accountants  from the Court Advisory  Service;  (v)
order the  Company  to pay  damages  for the harm and  losses  sustained  by Mr.
Valerio in terms of loss of  earnings  and  failure to receive due payment in an
amount such as shall be determined following preliminary  investigations and the
assessment to be made by experts and accountants from the Court Advisory Service
and in any event no less than 3 billion Lire ($18.9 million); and (vi) order the
Company to pay  damages for the harm done to Mr.  Valerio's  image for an amount
such as the judge shall deem  equitable and in case for no less than 500 million
Lire  ($3.1  million).  The  Company  retained  an  Italian  law firm as special
litigation counsel to the Company in its defense of this suit. On March 6, 1996,
the  Company,  through  its  Italian  counsel,  filed a brief of reply  with the
Tribunal of Milan  setting  forth the  Company's  position  that:  (i) the Civil
Tribunal of Milan is not the proper venue for the suit, (ii) Mr. Valerio's claim
is  groundless  since the parties  never  entered into an  agreement,  and (iii)
because Mr.  Valerio is not enrolled in the official  Register of Agents,  under
applicable  Italian law Mr. Valerio is not entitled to any  compensation for his
alleged  activities.  A preliminary  hearing before the Tribunal was held on May
30, 1996,  certain pretrial  discovery has been completed and a hearing before a
Discovery  Judge was held on October 17, 1996.  Submissions of the parties final
pleadings  were to be  made in  connection  with  the  next  hearing  which  was
scheduled for April 3, 1997. On April 3, 1997,  the  Discovery  Judge  postponed
this hearing to May 19, 1998, due to reorganization  of all proceedings  pending
before the Tribunal of Milan.  Management  is of the opinion that the lawsuit is
without  merit and will  contest it  vigorously.  In the opinion of  management,
after consultation with outside counsel, resolution of this suit should not have
a material  adverse  effect on the Company's  financial  position or operations.
However,  in the event  that the  lawsuit  does  result in a  substantial  final
judgment against the Company,  said judgment could have a severe material effect
on quarterly or annual operating results.

     On  September  16, 1997,  Ally  Capital  Corporation  ("Ally")  filed suit
against the Company,  John J. McCloy II,  Michael J.  Parrella,  Jay M. Haft and
Alistair  J. Keith in the  United  States  District  Court for the  District  of
Connecticut (the "District Court").  The complaint was not served on the Company
until January 15, 1998, and has yet to be served on the  individual  defendants.
The individual  defendants are current and former  officers and directors of the
Company.  The  complaint  alleges  three (3) causes of action  arising out of an
agreement (the "Asset Purchase  Agreement")  which the Company entered into with
another entity known as Active Noise and Vibration  Technologies,  Inc. ("ANVT")
whereby  the  Company   agreed  to  acquire   ANVT's   patented  and  unpatented
intellectual  property,  the  rights  and  obligations  under a defined  list of
agreements between ANVT and twenty-one (21) other parties (the "Listed Parties")
relating to existing or potential joint  ventures,  licensing and other business
relationships,  and certain items of office and laboratory equipment.  For these
assets,  the Company paid ANVT two hundred  thousand  ($200,000.00)  dollars and
issued ANVT two million  (2,000,000)  shares of the Company's  common stock. The
Asset Purchase Agreement also provided ANVT with the right to certain contingent
payments,  to the extent the Company  generated  certain  levels of revenue from
joint  venture,  licensing or other  contractual  relationships  with any of the
Listed  Parties.  Plaintiff  Ally is an unsecured  creditor of ANVT and is not a
party to the Asset Purchase Agreement; however, Ally asserts an interest to part
of the consideration paid ANVT by virtue of an escrow agreement between ANVT and
the escrow agent for the benefit of ANVT's secured and unsecured creditors. Ally
purports  to allege  claims of fraud,  negligent  misrepresentation  and a claim
under  the   Connecticut   Unfair  Trade   Practice  Act  based  upon  purported
representations  made to ANVT,  not Ally.  Thus,  it is alleged that the Company
isrepresented to ANVT the Company's financial  condition,  the number of shares
it could issue and the value of the  contingent  payment  rights under the Asset
Purchase  Agreement.  In  connection  with the claims,  Ally seeks  compensatory
damages in excess of one million two hundred thousand  ($1,200,000.00)  dollars,
punitive  damages and attorney  fees. On March 4, 1998,  the Company  served its
motion to dismiss the complaint  pursuant to Federal Rule of Civil Procedure 12.
The basis for the motion include: that the summons and complaint were not served
for more than one hundred  twenty (120) days after the complaint  was filed,  in
violation  of Federal  Rule of Civil  Procedure  4; that Ally lacks  standing to
bring  its  claims as they are based on  purported  representations  made by the
Company  to ANVT,  not Ally;  that the  claims are  legally  insufficient  under
Connecticut law; and that plaintiff has failed to join necessary  parties,  ANVT
and the  escrow  agent.  On March 16,  1998,  Ally  filed a notice of  voluntary
dismissal as to the individual defendants,  Messrs. McCloy,  Parrella,  Haft and
Keith.  As no  discovery  has taken  place,  the Company is unable to assess the
likelihood  of  an  adverse  result.   Management,   however,  believes  it  has
meritorious defenses and intends a vigorous defense of this lawsuit. However, in
the event this lawsuit does result in a substantial  final judgment  against the
Company,  said  judgment  could have a severe  material  effect on  quarterly or
annual operating results.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS

     There  were no matters  submitted to a vote of security holders during the
fourth quarter of the year ended December 31, 1997.

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

      Forward Looking Statements

   Statements in this filing which are not historical facts are  forward-looking
statements under provisions of the Private  Securities  Litigation Reform Act of
1995.  All  forward-looking  statements  involve  risks and  uncertainties.  The
Company wishes to caution readers that the following  important  factors,  among
others,  in some  cases  have  affected,  and in the future  could  affect,  the
Company's  actual  results and could cause its actual results in fiscal 1998 and
beyond  to  differ  materially  from  those  expressed  in  any  forward-looking
statements made by, or on behalf of, the Company.

   Important  factors  that could  cause  actual  results  to differ  materially
include but are not limited to the Company's ability to: achieve  profitability;
achieve a competitive position in design, development, licensing, production and
distribution of electronic  systems for Active Wave  Management;  produce a cost
effective  product  that will gain  acceptance  in relevant  consumer  and other
product  markets;   increase  revenues  from  products;   realize  funding  from
technology  licensing  fees,  royalties,  product  sales,  and  engineering  and
development revenues to sustain the Company's current level of operation; timely
introduce new products;  continue its current level of operations to support the
fees  associated  with the Company's  patent  portfolio;  maintain  satisfactory
relations  with its  five  customers  that  accounted  for 71% of the  Company's
revenues  in 1997;  attract  and retain  key  personnel;  prevent  invalidation,
abandonment or expiration of patents owned or licensed by the Company and expand
its patent  holdings to diminish  reliance on core  patents;  have its  products
utilized beyond noise attenuation and control; maintain and expand its strategic
alliances;  and  protect  Company  know-how,  inventions  and  other  secret  or
unprotected intellectual property.

      Overview

   The  Company  is  continuing  the  transition  initiated  in 1995 from a firm
focused  principally  on research and  development  of new  technology to a firm
focused on the  commercialization of its technology through technology licensing
fees,  royalties  and product  sales.  Prior to 1995,  the  Company  derived the
majority of its revenues from  engineering and development  funding  provided by
established  companies  willing to assist the Company in the  development of its
active noise and vibration  control  technology,  and from technology  licensing
fees paid by such companies. The Company's strategy generally has been to obtain
technology  licensing fees when initiating joint ventures and alliances with new
strategic  partners.  Revenues  from  product  sales  were  limited  to sales of
specialty products and prototypes.  In 1997, the Company received  approximately
6% of its operating revenues from engineering and development funding,  compared
with 17% in 1996.  Since 1991,  revenues from product sales have  generally been
increasing,  although in 1996 product sales  declined  slightly due to delays in
production  and reduced  pricing of certain  products.  In 1997,  revenues  from
product  sales  resumed its  year-to  year  increase.  Management  expects  that
technology licensing fees, royalties and product sales will become the principal
source of the  Company's  revenue  as the  commercialization  of its  technology
proceeds.

   As a result of the 1994  acquisition  of certain  ANVT  assets,  the  Company
became the  exclusive  licensee of ten  seminal  patents,  the Chaplin  Patents,
through its wholly owned  subsidiary,  CPH. The Company's ability to license the
Chaplin Patents directly to unaffiliated third parties provides the Company with
a greater  ability to earn  technology  licensing  fees and royalties  from such
patents.  Further, the Company believes that its intellectual property portfolio
prevents other competitors and potential competitors in the field of Active Wave
Management from  participating in certain commercial areas without licenses from
the Company.

     Subsequent  paragraphs  in  this  "Overview"),  Note 1 to the  accompanying
Consolidated  Financial  Statements and the  "Liquidity  and Capital  Resources"
section which  follows  describe the current  status of the Company's  available
cash balances.

     As  previously   disclosed,   the  Company   implemented   changes  in  its
organization  and focus in late  1994.  Additionally,  in late 1995 the  Company
redefined its corporate  mission to be the worldwide  leader in the  advancement
and  commercialization  of  Active  Wave  Management  technology.   Active  Wave
Management is the electronic and/or  mechanical  manipulation of sound or signal
waves to reduce  noise,  improve  signal-to-noise  ratio  and/or  enhance  sound
quality. This redefinition is the result of the development of new technologies,
as previously noted, such as ASF, TDSS, FPT(TM),  and the SMM, which the Company
believes can produce  products for fields beyond noise and  vibration  reduction
and control.  These  technologies  and products are consistent with shifting the
Company's focus to technology licensing and product marketing in more innovative
industries  having  greater  potential  for near term  revenue  generation.  The
redefinition  of corporate  mission is reflected  in the revised  business  plan
which the Company  began to implement  during the first  quarter of 1996 and has
continued through 1997.

  As  distribution  channels are  established  and as product  sales and market
acceptance  and  awareness  of the  commercial  applications  of  the  Company's
technologies  build as  anticipated  by  management,  revenues  from  technology
licensing fees, royalties and product sales are forecasted to fund an increasing
share  of the  Company's  requirements.  The  funding  from  these  sources,  if
realized,  will reduce the Company's  dependence on engineering  and development
funding.  The beginning of this process is shown in the shifting  percentages of
operating revenue, discussed below.

   In January 1996, the Company  adopted a plan that  management  believed would
generate  sufficient funds for the Company to continue its operations into 1997.
The  Company  did not meet the plan's  revenue  targets  for 1996 or 1997 and as
noted  below,  found it  necessary  to raise  additional  capital  to fund  it's
operations for 1997 and beyond (refer to "Liquidity and Capital Resources" below
and to Notes 1 and 6 - "Notes to the Consolidated Financial Statements.").

   Success in generating  technology licensing fees, royalties and product sales
are  significant  and  critical to the  Company's  success.  The Company  cannot
predict whether it will be successful in obtaining market  acceptance of its new
products or in completing its current  negotiations with respect to licenses and
royalty revenues.

   From the  Company's  inception  through  December  31,  1997,  its  operating
revenues,  including technology licensing fees and royalties,  product sales and
engineering  and  development  services,  have  consisted of  approximately  23%
product  sales,  46%  engineering  and  development  services and 31% technology
licensing fees.

   The  Company  has  entered   into  a  number  of  alliances   and   strategic
relationships  with established firms for the integration of its technology into
products.  The speed with which the Company can achieve the commercialization of
its  technology  depends in large  part upon the time  taken by these  firms and
their  customers  for  product  testing,  and  their  assessment  of how best to
integrate  the  Company's   technology   into  their  products  and  into  their
manufacturing  operations.  While the Company  works with these firms on product
testing and  integration,  it is not always able to  influence  how quickly this
process can be completed.

   The Company began  shipping  ProActive(TM)  headsets in 1995 and continues to
sell  NoiseBuster  Extreme!(TM)  consumer  headsets.  The Company is now selling
products  through three of its alliances:  Walker is  manufacturing  and selling
industrial  silencers;  Siemens is buying and  contracting  with the  Company to
install quieting  headsets for patient use in Siemens' MRI machines;  and in the
fourth quarter of 1994 Ultra began  installing  production  model aircraft cabin
quieting systems in the SAAB 340 turboprop  aircraft.  Management believes these
developments  and  those  previously  disclosed  help  demonstrate  the range of
commercial  potential for the Company's  technology  and will  contribute to the
Company's  transition from  engineering and development to technology  licensing
fees, royalties and product sales.

   The  availability  of  high-quality,   low-cost  electronic   components  for
integration   into   the   Company's   products   also   is   critical   to  the
commercialization of the Company's  technology.  The Company is working with its
strategic  partners  and  other  suppliers  to  reduce  the size and cost of the
Company's  systems,  so  that  the  Company  will  be  able  to  offer  low-cost
electronics and other components suitable for high-volume production.

   The Company has continued to make  substantial  investments in its technology
and  intellectual  property and has incurred  development  costs for engineering
prototypes,  pre-production models and field testing of several products. During
1994,  the  Company   acquired  a  license  to  two  patents  in  the  field  of
micro-machined  microphones and concluded the acquisition of all of the patents,
know-how and intellectual property of a former competitor, ANVT. During 1995 the
Company  acquired  several U.S.  patents dealing with adaptive speech  filtering
which is used in the  Company's  ClearSpeech(TM)  product line. In 1996 and 1997
the Company was granted 90 new patents for various  applications in the field of
Active Wave Management. Management believes that the Company's investment in its
technology has resulted in the expansion of its intellectual  property portfolio
and improvement in the functionality, speed and cost of components and products.

   The  Company  has  become   certified  under  the   International   Standards
Organization  product quality program known as "ISO 9000",  and has successfully
undergone two quality  audits.  Since the third quarter of 1994, the Company has
reduced its worldwide  work force by 51% from 173 to 85 current  employees as of
February 28, 1998.

   Because the Company  did not meet its revenue  targets for 1996 and 1997,  it
entered into certain transactions, which provided additional funding as follows:

     Between January 15, 1997 and March 25, 1997, the Company issued and sold an
aggregate  amount  of  $3.4  million  of  non-voting  subordinated   convertible
debentures (the "Debentures") in a private placement pursuant to Regulation S of
the Securities Act of 1933, as amended, (the "Securities Act") to five unrelated
investors (the  "Investors")  through  multiple dealers (the "First Quarter 1997
Financing")  from which the Company  realized $3.2 million of net proceeds.  The
Debentures  were to mature between  January 15, 2000 and March 25, 2000 and earn
8% interest per annum,  payable quarterly in either cash or the Company's common
stock at the  Company's  sole  option.  Subject to certain  common  stock resale
restrictions,  the Investors, at their discretion,  had the right to convert the
principal  due on the  Debentures  into the  Company's  common stock at any time
after  the 45th day  following  the  date of the sale of the  Debentures  to the
Investors.  In the  event of such a  conversion,  the  conversion  price was the
lesser of 85% of the  closing  bid price of the  Company's  common  stock on the
closing date of the  Debentures'  sale or between 75% to 60%  (depending  on the
Investor  and other  conditions)  of the average  closing bid price for the five
trading days  immediately  preceding  the  conversion.  To provide for the above
noted conversion and interest  payment options,  the Company reserved 15 million
shares of the Company's common stock for issuance upon such conversion.  Subject
to certain  conditions,  the Company also had the right to require the Investors
to convert all or part of the Debentures  under the above noted conversion price
conditions  after  February  15, 1998.  As of June 6, 1997,  the  Investors  had
converted  all $3.4 million of the  Debentures  into 16.3 million  shares of the
Company's  common  stock.  At the Company's  election,  interest due through the
conversion  dates  of  the  Debentures  was  paid  through  the  issuance  of an
additional 0.2 million shares of the Company's common stock. In conjunction with
the  Debentures,  the  Company  granted a warrant to purchase  75,000  shares of
common stock to one  investor.  During the year ended  December  31,  1997,  the
Company valued this warrant,  using the  Black-Scholes  pricing model,  at which
$34,000  which was  expensed as debt  discount.  The Company has recorded a $1.4
million  non-cash  interest  expense  attributable  to  the  conversions  of the
Debentures in the first and second  quarter of 1997 as an adjustment  during the
fourth  quarter  of  1997.  If the  shares  were  issued  in lieu of debt at the
respective issuance dates of the debt,  supplementary basic and diluted net loss
per share for the year ended  December  31, 1997 would have been a loss of $0.08
per share.

   On July 30, 1997, in a private placement pursuant to Section 4(2) of the Act,
the Company sold 2.9 million shares, in the aggregate,  of its common stock at a
price of $0.175 per share that  provided  net  proceeds  to the  Company of $0.5
million (the "July 30, 1997 Private Placement").

     On September 4, 1997,  the Company  transferred  $5,000 cash and all of the
business  and assets of its Audio  Products  Division as then  conducted  by the
Company and as reflected  on the business  books and records of the Company to a
newly incorporated  company, NCT Audio, in consideration for 5,867 shares of NCT
Audio common stock  whereupon NCT Audio became a wholly owned  subsidiary of the
Company.  The Company also granted NCT Audio an exclusive worldwide license with
respect to all of the  Company's  relevant  patented and  unpatented  technology
relating to FPT(TM) and FPT(TM) based audio speaker products for all markets for
such products  excluding  (a) markets  licensed to or reserved by Verity and NXT
under the  Company's  cross  licensing  agreements  with Verity and NXT, (b) the
ground based  vehicle  market  licensed to OAT, (c) all markets for hearing aids
and other  hearing  enhancing  or  assisting  devices,  and (d) all  markets for
headsets,  headphones and other products performing functions  substantially the
same as those performed by such products in  consideration  for a license fee of
$3.0 million to be paid when proceeds are  available  from the sale of NCT Audio
common stock and on-going future  royalties  payable by NCT Audio to the Company
as  provided in such  license  agreement.  In  addition,  the Company  agreed to
transfer all of its rights and obligations under its cross licensing  agreements
with Verity and NXT to NCT Audio and to transfer the  Company's  interest in OAT
to NCT Audio.  Between  October 10, 1997 and  December 4, 1997 NCT Audio  issued
2,145 shares of its common stock  (including 533 shares issued to Verity) for an
aggregate  purchase  price of $4.0  million in a private  placement  pursuant to
Regulation D under the Securities Act (the "NCT Audio Financing"). NCT Audio has
not met certain conditions regarding the filing of a registration  statement for
NCT Audio common stock. As such,  holders of NCT Audio common stock have a right
to convert  their NCT Audio common stock into a sufficient  number of restricted
shares of NCT common stock to equal their original cash investment in NCT Audio,
plus a 20% discount to market. As of February 27, 1998, no NCT Audio shareholder
has  exercised  their  right to convert NCT Audio  common  stock into NCT common
stock under the terms noted above.

     Between  October 28, 1997 and December 11, 1997, the Company entered into a
series of  subscription  agreements (the  "Subscription  Agreements") to sell an
aggregate  amount of $13.3 million of Series C Convertible  Preferred Stock (the
"Preferred  Stock") in a private  placement,  pursuant  to  Regulation  D of the
Securities Act, to 32 unrelated  accredited  investors  through two dealers (the
"1997  Preferred Stock Private  Placement").  The total Preferred Stock offering
was completed on December 11, 1997. The aggregate net proceeds to the Company of
the 1997 Preferred Stock Private Placement were $11.9 million. Each share of the
Preferred  Stock has a par  value of $.10 per  share  and a stated  value of one
thousand  dollars ($1,000) with an accretion rate of four percent (4%) per annum
on the stated value.  Each share of Preferred  Stock is  convertible  into fully
paid and  nonassessable  shares of the Company's Common Stock subject to certain
limitations.  Under the terms of the  Subscription  Agreements  the  Company was
required  to  exercise  its  best  efforts  to  file  a  registration  statement
("Registration  Statement")  on Form S-3  covering  the  resale of all shares of
Common Stock of the Company issuable upon conversion of the Preferred Stock then
outstanding within sixty (60) days after the first Closing of the 1997 Preferred
Stock Private Placement.  Such Registration  Statement was filed with the SEC on
December 29, 1997. The shares of Preferred Stock become  convertible into shares
of Common Stock at any time  commencing  after the earlier of (i) the  effective
date of the  Registration  Statement;  or ii) ninety (90) days after the date of
filing  of  the  Registration  Statement.  Each  share  of  Preferred  Stock  is
convertible into a number of shares of Common Stock of the Company as determined
in accordance with the following formula (the "Conversion Formula"):

                                     [(.04) x (N/365) x (1,000)] + 1,000
                                               Conversion Price

      where

            N           = the number of days between (i) the Closing Date of the
                        Series C Convertible  Preferred  Stock being  converted,
                        and (ii) the Conversion Date thereof.

            Conversion
            Price       = the  lesser  of (x) 120% of the  five (5) day  average
                        Closing Bid Price of Common Stock  immediately  prior to
                        the Closing Date of the Series C  Convertible  Preferred
                        Stock being  converted or (y) 20% below the five (5) day
                        average  Closing Bid Price of Common  Stock  immediately
                        prior to the Conversion Date thereof.

            Closing
            Date        =  the  date  of  the   Closing  as  set  forth  in  the
                        subscription   agreement  pertaining  to  the  Series  C
                        Convertible Preferred Stock being converted.


   The  conversion  terms of the  Preferred  Stock also provide that in no event
shall the average  closing bid price  referred to in the  Conversion  Formula be
less than  $0.625 per share and in no event shall the  Company be  obligated  to
issue more than 26.0  million  shares of its Common  Stock in the  aggregate  in
connection  with the conversion of the Preferred  Stock.  Under the terms of the
Subscription  Agreements  the  Company  may  be  subject  to a  penalty  if  the
Registration Statement is not declared effective within one hundred twenty (120)
days after the first  closing of any  incremental  portion  of the  offering  of
Preferred  Stock,  such  penalty  to be in an  amount  equal to one and one half
percent (1.5%) per month of the aggregate  amount of Preferred Stock sold in the
offering  up to a maximum of ten percent  (10%) of such  aggregate  amount.  The
Subscription Agreements also provide that for a period commencing on the date of
the signing of the Subscription Agreements and ending ninety (90) days after the
closing of the offering the Company will be prohibited  from issuing any debt or
equity  securities  other than Preferred Stock, and that the Corporation will be
required  to make  certain  payments  in the  event  of its  failure  to  effect
conversion  in a timely  manner or in the event it fails to  reserve  sufficient
authorized  but  unissued  Common  Stock for  issuance  upon  conversion  of the
Preferred Stock.

     Cash and cash  equivalents  amounted to $12.6 million at December 31, 1997.
Management  believes  that  currently  available  funds may not be sufficient to
sustain the Company for the next 12 months. Such funds consist of available cash
and cash from the  exercise of warrants and  options,  the funding  derived from
technology   licensing  fees,   royalties  and  product  sales  and  engineering
development  revenue.  Reducing operating expenses and capital expenditure alone
may not be sufficient and  continuation as a going concern is dependent upon the
level of realization of funding from technology licensing fees and royalties and
product  sales  and  engineering  and  development  revenue,  all of  which  are
presently uncertain.  In the event that technology licensing fees, royalties and
product  sales,  and  engineering  and  development  revenue are not realized as
planned,  then management  believes additional working capital financing must be
obtained. There is no assurance any such financing is or would become available.

     There can be no  assurance  that  funding  will be provided  by  technology
license  fees,  royalties  and product  sales and  engineering  and  development
revenue.  In that event,  the Company would have to  substantially  cut back its
level of  operations.  These  reductions  could  have an  adverse  effect on the
Company's  relations  with its  strategic  partners and  customers.  Uncertainty
exists with  respect to the adequacy of current  funds to support the  Company's
activities  until positive cash flow from  operations can be achieved,  and with
respect to the  availability  of financing  from other  sources to fund any cash
deficiencies.

     The accompanying  financial statements have been prepared assuming that the
Company will  continue as a going  concern,  which  contemplates  continuity  of
operations,  realization  of  assets  and  satisfaction  of  liabilities  in the
ordinary  course of business.  The propriety of using the going concern basis is
dependent  upon,  among  other  things,  the  achievement  of future  profitable
operations and the ability to generate  sufficient cash from operations,  public
and private  financings and other funding sources to meet its  obligations.  The
uncertainties  described in the preceding  paragraphs raise substantial doubt at
December 31, 1997 about the  Company's  ability to continue as a going  concern.
The accompanying financial statements do not include any adjustments relating to
the  recoverability  of the carrying  amount of recorded assets or the amount of
liabilities that might result from the outcome of these uncertainties.


     Results of Operations

Year ended December 31, 1997 compared with year ended December 31, 1996.

   Total  revenues in 1997 increased by 81% to $5.7 million from $3.2 million in
1996.  Total expenses  during the same period  increased by 11% or $1.6 million,
primarily   reflecting  the  one-time  $1.4  million  non-cash  interest  charge
associated  with the First  Quarter 1997  Financing.  See Note 6 - "Notes to the
Consolidated Financial Statements."

   Technology  licensing fees and royalties increased by 193% or $2.4 million to
$3.6 million from $1.2 million in 1996. The 1996 amount was derived  principally
from  numerous  technology  license fees  reflecting  the  Company's  continuing
emphasis  on  expanding  technology  license  fee  revenue.  The 1997  amount is
primarily due to the $3.0 million  technology  license fee from Verity and other
technology  licensing fees aggregating $0.6 million.  See Note 3 - "Notes to the
Consolidated Financial Statements".

   Product  sales  increased in 1997 by 25% to $1.7 million from $1.4 million in
1996  reflecting  increases in  NoiseBuster  Extreme!(TM)  and aviation  headset
sales.

  Engineering  and development  services  decreased by 33% to $0.4 million from
$0.5  million  in  1996,   primarily  due  to  the  de-emphasis  of  engineering
development funding as a primary source of revenue for the Company.

   Cost of product sales increased 44% to $2.3 million from $1.6 million in 1996
and the  product  margin  decreased  to (32)% from (15)% in 1996.  The  negative
margin of $0.6  million in 1997 was  primarily  due to  reserves  for  inventory
movement and tooling  obsolescence  in the amount of $0.7 million related to the
industrial  headset product lines. The negative margin in 1996 was primarily due
to a  lower  sales  price  of  the  NoiseBuster(R)  and a  reserve  for  tooling
obsolescence in the amount of $0.3 million.

   Cost of engineering  and development  services  increased 26% to $0.3 million
from $0.2  million  in 1996  primarily  due to the  de-emphasis  of  engineering
development  funding  as a primary  source of revenue  for the  Company as noted
above.

   Selling,  general and administrative expenses for the year increased by 7% or
$0.3 million to $5.2 million from $4.9 million for 1996 which was  primarily due
to increased professional fees and related expenses.

   Depreciation and amortization included in selling, general and administrative
expenses  decreased  from  $0.5  million  in 1996 to  $0.4  primarily  due to an
increase in fully depreciated machinery and equipment.

   Research  and  development  expenditures  for 1997  decreased  by 11% to $6.2
million  from $7.0  million in 1996,  primarily  due to limited  cash  resources
during most of 1997 to fund internal development projects.

   In 1997,  interest  income  increased  to $0.1 million from near zero in 1996
reflecting the increase in late 1997 of available funds to invest.

   Under all of the Company's  existing  joint venture  agreements at the end of
1997,  the Company was not  required to fund any capital  requirements  of these
joint ventures beyond its initial capital contribution.  In accordance with U.S.
generally accepted accounting principles, when the Company's share of cumulative
losses equals its  investment  and the Company has no obligation or intention to
fund such additional  losses, the Company suspends applying the equity method of
accounting for its investment.

   The  Company  has net  operating  loss  carryforwards  of $76.9  million  and
research and development credit carryforwards of $1.3 million for federal income
tax purposes at December 31, 1997. No tax benefit for these operating losses has
been recorded in the Company's  financial  statements.  The Company's ability to
utilize  its net  operating  loss  carryforwards  may be  subject  to an  annual
limitation.

Year ended December 31, 1996 compared with year ended December 31, 1995.

   Total  revenues in 1996  decreased by 70% to $3.2 million from $10.5 in 1995.
Total  expenses  during  the  same  period  decreased  by  4% or  $0.5  million,
reflecting the continuing  results of cost reduction  plans,  and the refocus of
expenditures to more immediate markets.

   Technology  licensing  fees decreased by 81% or $5.3 million to $1.2 million.
The 1995 amount was derived  principally  from a $2.6  million  license fee from
Ultra, a $ 3.3 million  license fee from Walker and other  licenses  aggregating
$0.7  million.  The 1996 amount is derived from smaller,  more numerous  license
fees,  reflecting  the  Company's  continuing  emphasis on expanding  technology
licensing fee revenue and the  shortfall in generation of such revenue  referred
to above. See Note 3 - "Notes to the Consolidated Financial Statements".

   Product sales decreased by 13% to $1.4 million reflecting  decreased aviation
headset sales, decreased  NoiseBuster(R) sales at lower prices and a decrease in
industrial  silencer  sales in connection  with the transfer of that business to
Walker.

   Engineering  and  development  services  decreased  by 76% to  $0.5  million,
primarily due to a de-emphasis of engineering  development  funding as a primary
source of revenue,  the  elimination  of funding from Ultra for  aircraft  cabin
quieting in connection  with the transfer of that business to Ultra in the first
quarter of 1995,  a decrease in the amount of muffler  development  funding from
Walker in connection  with the transfer of that business to Walker in the fourth
quarter of 1995 and staff reductions.

   Cost of product sales  remained  unchanged at $1.6 million and product margin
decreased to (15)% from 1% in 1995.  The negative  margin in 1996 was  primarily
due to the lower  sales  price of the  NoiseBuster(R)  and a reserve for tooling
obsolescence in the amount of $0.3 million.  In 1995, the low product margin was
primarily due to the lower sales price of the NoiseBuster(R).

     Cost of engineering and development  services decreased 89% to $0.3 million
primarily due to the changes noted above.

   Selling, general and administrative expenses for the year decreased by 10% to
$4.9  million  from $5.4 million for 1995.  Of this  decrease,  $0.6 million was
directly   attributable   to  reductions  in  salaries  and  related   expenses.
Advertising   and  marketing   expenses   decreased  by  32%  to  $0.5  million.
Professional  fees  increased by 6% to $1.8  million.  Travel and  entertainment
increased by 18% or $0.1 million.

   Depreciation and amortization included in selling, general and administrative
expenses  increased by $0.3 million or 143%,  from $0.2 million to $0.5 million,
primarily due to increased amortization of patents allocated to selling, general
and administrative expenses from research and development.

   Research  and  development  expenditures  for 1996  increased  by 46% to $7.0
million from $4.8  million for 1995,  primarily  due to increases to  internally
funded development projects.

   In 1996,  interest  income  decreased  to near zero from $0.1 million in 1995
reflecting the decrease in 1996 of available funds to invest.

   Under all of the Company's  existing  joint venture  agreements at the end of
1997,  the Company was not  required to fund any capital  requirements  of these
joint ventures beyond its initial capital contribution.  In accordance with U.S.
generally accepted accounting principles, when the Company's share of cumulative
losses equals its  investment  and the Company has no obligation or intention to
fund such additional  losses, the Company suspends applying the equity method of
accounting for its investment.  As of December 31, 1995, the Company  recognized
$80,000 of income  relating to its 1995 profit in OAT. As of December  31, 1996,
the Company  reversed  the $80,000 of income  which  related to its share of the
1996 loss in OAT.

      Liquidity and Capital Resources

   The  Company  received  $1.1  million  from the  exercise  of stock  purchase
warrants and options during 1997, $1.0 million in 1996 and $0.7 million in 1995.

   In January 1996, the Company  adopted a plan that  management  believed would
generate  sufficient funds for the Company to continue its operations into 1997.
The  Company  did not meet the plan's  revenue  targets  for 1996 or 1997 and as
noted  below,  found it  necessary  to raise  additional  capital  to fund  it's
operations  for  1997 and  beyond  (refer  to  Notes  1 and 6 - "Notes  to the
Consolidated Financial Statements.").

   Because the Company  did not meet its  revenue  targets for 1997,  it entered
into certain transactions, which provided additional funding as follows:

     Between January 15, 1997 and March 25, 1997, the Company issued and sold an
aggregate  amount of $3.4 million of the  Debentures  in the First  Quarter 1997
Financing  from which the Company  realized  $3.2 million of net  proceeds.  The
Debentures  were to mature between  January 15, 2000 and March 25, 2000 and earn
8% interest per annum,  payable quarterly in either cash or the Company's common
stock at the  Company's  sole  option.  Subject to certain  common  stock resale
restrictions,  the Investors, at their discretion,  had the right to convert the
principal  due on the  Debentures  into the  Company's  common stock at any time
after  the 45th day  following  the  date of the sale of the  Debentures  to the
Investors.  In the  event of such a  conversion,  the  conversion  price was the
lesser of 85% of the  closing  bid price of the  Company's  common  stock on the
closing date of the  Debentures'  sale or between 75% to 60%  (depending  on the
Investor  and other  conditions)  of the average  closing bid price for the five
trading days  immediately  preceding  the  conversion.  To provide for the above
noted conversion and interest  payment options,  the Company reserved 15 million
shares of the Company's common stock for issuance upon such conversion.  Subject
to certain  conditions,  the Company also had the right to require the Investors
to convert all or part of the Debentures  under the above noted conversion price
conditions  after  February  15, 1998.  As of June 6, 1997,  the  Investors  had
converted  all $3.4 million of the  Debentures  into 16.3 million  shares of the
Company's  common  stock.  At the Company's  election,  interest due through the
conversion  dates  of  the  Debentures  was  paid  through  the  issuance  of an
additional 0.2 million shares of the Company's common stock. In conjunction with
the  Debentures,  the  Company  granted a warrant to purchase  75,000  shares of
common stock to one  investor.  During the year ended  December  31,  1997,  the
Company valued this warrant,  using the  Black-Scholes  pricing model,  at which
$34,000  which was  expensed as debt  discount.  The Company has  recorded  $1.4
million of non-cash  interest  expense  attributable  to the  conversions of the
Debentures in the first and second  quarter of 1997 as an adjustment  during the
fourth  quarter  of  1997.  If the  shares  were  issued  in lieu of debt at the
respective issuance dates of the debt,  supplementary basic and diluted net loss
per share for the year ended  December  31, 1997 would have been a loss of $0.08
per share.

  On July 30, 1997 the Company sold 2.9 million  shares,  in the aggregate,  of
its  common  stock at a price of $0.175 per share in the July 30,  1997  Private
Placement that provided net proceeds to the Company of $0.5 million.

     On September 4, 1997,  the Company  transferred  $5,000 cash and all of the
business  and assets of its Audio  Products  Division as then  conducted  by the
Company and as reflected  on the business  books and records of the Company to a
newly incorporated  company, NCT Audio, in consideration for 5,867 shares of NCT
Audio common stock  whereupon NCT Audio became a wholly owned  subsidiary of the
Company.  The Company also granted NCT Audio an exclusive worldwide license with
respect to all of the  Company's  relevant  patented and  unpatented  technology
relating to FPTs(TM) and FPT(TM)  based audio  speaker  products for all markets
for such products  excluding  (a) markets  licensed to or reserved by Verity and
NXT under the Company's cross licensing  agreements with Verity and NXT, (b) the
ground based  vehicle  market  licensed to OAT, (c) all markets for hearing aids
and other  hearing  enhancing  or  assisting  devices,  and (d) all  markets for
headsets,  headphones and other products performing functions  substantially the
same as those performed by such products in  consideration  for a license fee of
$3.0  million  (eliminated  on  consolidation)  to be  paid  when  proceeds  are
available from the sale of NCT Audio common stock and on-going future  royalties
payable by NCT Audio to the Company as provided in such  license  agreement.  In
addition, the Company agreed to transfer all of its rights and obligations under
its cross licensing  agreements with Verity and NXT to NCT Audio and to transfer
the  Company's  interest  in OAT to NCT  Audio.  Between  October  10,  1997 and
December 4, 1997 NCT Audio issued  2,145  shares of its common stock  (including
533 shares issued to Verity) for an aggregate  purchase price of $4.0 million in
the NCT Audio Financing.  NCT Audio has not met certain conditions regarding the
filing of a registration  statement for NCT Audio common stock. As such, holders
of NCT Audio common  stock have a right to convert  their NCT Audio common stock
into a sufficient number of restricted shares of NCT common stock to equal their
original  cash  investment  in NCT Audio,  plus a 20% discount to market.  As of
February 27, 1998, no NCT Audio shareholder has exercised their right to convert
NCT Audio common stock into NCT common stock under the terms noted above.

   Between  October 28, 1997 and December 11, 1997, the Company entered into the
Subscription  Agreements  to sell an  aggregate  amount of $13.3  million of the
Preferred  Stock  in the 1997  Preferred  Stock  Private  Placement.  The  total
Preferred  Stock  offering was completed on December 11, 1997. The aggregate net
proceeds to the Company of the 1997 Preferred Stock Private Placement were $11.9
million. Each share of the Preferred Stock has a par value of $.10 per share and
a stated value of one thousand  dollars  ($1,000) with an accretion rate of four
percent (4%) per annum on the stated  value.  Each share of  Preferred  Stock is
convertible  into fully paid and  nonassessable  shares of the Company's  Common
Stock  subject  to  certain  limitations.  Under the  terms of the  Subscription
Agreements  the Company was  required  to  exercise  its best  efforts to file a
Registration  Statement covering the resale of all shares of Common Stock of the
Company issuable upon conversion of the Preferred Stock then outstanding  within
sixty (60) days  after the first  Closing of the 1997  Preferred  Stock  Private
Placement.  The  Registration  Statement  was filed with the SEC on December 29,
1997.  The shares of Preferred  Stock become  convertible  into shares of Common
Stock at any time commencing  after the earlier of (i) the effective date of the
Registration Statement; or (ii) ninety (90) days after the date of filing of the
Registration  Statement.  Each share of Preferred  Stock is  convertible  into a
number of shares of Common Stock of the Company as determined in accordance with
the Conversion Formula described above under "Overview".

   The  conversion  terms of the  Preferred  Stock also provide that in no event
shall the average  closing bid price  referred to in the  Conversion  Formula be
less than  $0.625 per share and in no event shall the  Company be  obligated  to
issue more than 26.0  million  shares of its Common  Stock in the  aggregate  in
connection  with the conversion of the Preferred  Stock.  Under the terms of the
Subscription  Agreements  the  Company  may  be  subject  to a  penalty  if  the
Registration Statement is not declared effective within one hundred twenty (120)
days after the first  closing of any  incremental  portion  of the  offering  of
Preferred  Stock,  such  penalty  to be in an  amount  equal to one and one half
percent (1.5%) per month of the aggregate  amount of Preferred Stock sold in the
offering  up to a maximum of ten percent  (10%) of such  aggregate  amount.  The
Subscription Agreements also provide that for a period commencing on the date of
the signing of the Subscription Agreements and ending ninety (90) days after the
closing of the offering the Company will be prohibited  from issuing any debt or
equity  securities  other than Preferred Stock, and that the Corporation will be
required  to make  certain  payments  in the  event  of its  failure  to  effect
conversion  in a timely  manner or in the event it fails to  reserve  sufficient
authorized  but  unissued  Common  Stock for  issuance  upon  conversion  of the
Preferred Stock.

     Management believes that currently available funds may not be sufficient to
sustain the Company for the next 12 months. Such funds consist of available cash
and cash from the  exercise of warrants and  options,  the funding  derived from
technology   licensing  fees,   royalties  and  product  sales  and  engineering
development  revenue.  Reducing operating expenses and capital expenditure alone
may not be sufficient and  continuation as a going concern is dependent upon the
level of realization of funding from technology licensing fees and royalties and
product  sales  and  engineering  and  development  revenue,  all of  which  are
presently uncertain.  In the event that technology licensing fees, royalties and
product  sales,  and  engineering  and  development  revenue are not realized as
planned,  then management  believes additional working capital financing must be
obtained. There is no assurance any such financing is or would become available.

     There can be no  assurance  that  funding  will be provided  by  technology
license  fees,  royalties  and product  sales and  engineering  and  development
revenue.  In that event,  the Company would have to  substantially  cut back its
level of  operations.  These  reductions  could  have an  adverse  effect on the
Company's  relations  with its  strategic  partners and  customers.  Uncertainty
exists with  respect to the adequacy of current  funds to support the  Company's
activities  until positive cash flow from  operations can be achieved,  and with
respect to the  availability  of financing  from other  sources to fund any cash
deficiencies.

     The accompanying  financial statements have been prepared assuming that the
Company will  continue as a going  concern,  which  contemplates  continuity  of
operations,  realization  of  assets  and  satisfaction  of  liabilities  in the
ordinary  course of business.  The propriety of using the going concern basis is
dependent  upon,  among  other  things,  the  achievement  of future  profitable
operations and the ability to generate  sufficient cash from operations,  public
and private  financings and other funding sources to meet its  obligations.  The
uncertainties  described in the preceding  paragraphs raise substantial doubt at
December 31, 1997 about the  Company's  ability to continue as a going  concern.
The accompanying financial statements do not include any adjustments relating to
the  recoverability  of the carrying  amount of recorded assets or the amount of
liabilities that might result from the outcome of these uncertainties.

   The  Company  has  incurred  substantial  losses  from  operations  since its
inception,  which  have  been  recurring  and  amounted  to $93.5  million  on a
cumulative  basis through  December 31, 1997.  These  losses,  which include the
costs for development of products for commercial use, have been funded primarily
from the sale of common stock,  including the exercise of warrants or options to
purchase  common  stock,  and  by  technology   licensing  and  engineering  and
development  funds  received  from joint venture and other  strategic  partners.
Agreements with joint venture and other  strategic  partners  generally  require
that a portion of the initial cash flows,  if any,  generated by the ventures or
alliances be paid on a preferential  basis to the Company's  co-venturers  until
the license fees and engineering  and development  funds provided to the venture
or the Company are recovered.

     In January 1998, the Company adopted a plan that management believes should
generate sufficient  additional funds for the Company to continue its operations
into 1999.  Under this plan, the Company needs to generate  approximately  $31.5
million to fund its operations in 1998. Included in such amount is approximately
$23.3  million  in sales of new  products  and  approximately  $8.1  million  of
technology  licensing  fees and  royalties.  The  Company  believes  that it can
generate these funds from 1998  operations,  although there is no certainty that
the Company will achieve this goal. Success in generating  technology  licensing
fees,  royalties and product sales are significant and critical to the Company's
ability to succeed.  The Company cannot predict whether it will be successful in
obtaining  market  acceptance of its new products or in  completing  its current
negotiations  with  respect to licenses  and royalty  revenues.  If,  during the
course of 1998,  management of the Company  determines that it will be unable to
meet or  exceed  the plan  discussed  above,  the  Company  will  consider  cost
reductions and/or additional  financing  alternatives.  The Company will monitor
its  performance  against the plan on a monthly basis and, if necessary,  reduce
its  level  of  operations  accordingly.  The  Company  believes  that  the plan
discussed above  constitutes a viable plan for the continuation of the Company's
business into 1999. See "Forward Looking Statements" above.

     There can be no  assurance  that  additional  funding  will be  provided by
technology licensing fees, royalties, product sales, engineering and development
revenue or additional capital. In that event, the Company would have to cut back
its  level  of  operations  substantially  in  order  to  conserve  cash.  These
reductions  could have an adverse  effect on the  Company's  relations  with its
strategic  partners  and  customers.  See  Note 1 - "Notes  to the  Consolidated
Financial Statements".

   At December 31,  1997,  cash and cash  equivalents  were $12.6  million.  The
available  resources were invested in interest bearing money market accounts and
commercial paper. The Company's  investment objective is preservation of capital
while earning a moderate rate of return.

   The Company's  working capital  increased from $(1.3) million at December 31,
1996, to $11.7 million as of December 31, 1997.  This increase was due primarily
to the 1997 financings discussed above.

   During 1997, the net cash used in operating activities was $7.4 million. This
utilization  reflects  the  emphasis  on  the  commercial   development  of  its
technology   into  several  product   applications   which  were  scheduled  for
introduction in 1997 and 1998.

   The  Company's  available  cash balances at December 31, 1997 are higher than
projected at the end of 1996, primarily due to the 1997 financings noted above.

   The net cash used in investing activities amounted to $0.2 million during the
year  primarily  for capital  expenditures.  The net cash  provided by financing
activities  amounted to $19.9 million primarily from the exercise of options and
warrants and the 1997 financings noted above.

   The Company has no lines of credit with banks or other  lending  institutions
and therefore has no unused borrowing capacity.

   The Company believes that the level of financial resources available to it is
an  essential  competitive  factor.  The Company  may elect to raise  additional
capital,  from  time to  time,  through  equity  or debt  financing  in order to
capitalize on business opportunities and market conditions.

     Capital Expenditures

   The Company intends to continue its business strategy of working with supply,
manufacturing,   distribution  and  marketing   partners  to  commercialize  its
technology.  The benefits of this strategy  include:  (i) dependable  sources of
electronic and other  components,  which  leverages on their  purchasing  power,
provides  important  cost savings and accesses the most  advanced  technologies;
(ii) utilization of the manufacturing capacity of the Company's allies, enabling
the Company to  integrate  its active  technology  into  products  with  limited
capital   investment;   and  (iii)  access  to   well-established   channels  of
distribution and marketing capability of leaders in several market segments.

   There were no material  commitments  for capital  expenditures as of December
31, 1997, and no material commitments are anticipated in the near future.

   Year 2000 Compliance

   The Company  believes  the cost of  administrating  its Year 2000  Compliance
program will not have a material adverse impact on future earnings. However, the
potential  costs and  uncertainties  associated  with any Year  2000  Compliance
program will depend on a number of factors, including software, hardware and the
nature of the industry in which the Company,  its  subsidiaries,  suppliers  and
customers  operate.  In addition,  companies must coordinate with other entities
with which they electronically interact, such as customers, suppliers, financial
institutions, etc.

   Although the Company's  evaluation of its systems is still in process,  there
has been no indication  that the Year 2000  Compliance  issue,  as it relates to
internal  systems,  will have a material  impact on future  earnings.  While the
Company  is not  aware  of any  material  Year  2000  Compliance  issues  at its
customers and suppliers,  such potential problems remain a possibility and could
have a material adverse impact on the Company's future results.

September,  1983 as Manager,  International  Cash  Management and served in that
capacity until April,  1986. From February,  1981 to April, 1983 he was employed
as a Foreign  Exchange/Cash Manager at Atlas Copco AB. Mr. Carlquist serves as a
member of the following  Boards:  ABB  Financial  Services,  Inc.,  ABB Treasury
Center USA, Inc., ABB Treasury Center  (Canada),  ABB Treasury Center  (Brazil),
ABB Project & Trade Finance,  Inc., ABB Investment Management  Corporation,  ABB
Credit, Inc., Sirius Americas Corporation,  ABB Industrial Systems,  Inc., SUSA,
Inc., and Swedish-American Chamber of Commerce, New York.

   Morton Salkind currently serves as a Director of the Company. Mr. Salkind was
elected as a Director of the Company's subsidiary,  NCT Audio Products, Inc., on
September 4, 1997 and  currently  also serves as a Director of that  subsidiary.
Formerly he served as a New Jersey State  Lottery  Commissioner  for five years.
This followed previous elective and appointive offices at the state,  county and
municipal levels. Mr. Salkind is currently retired.

     Section  16(a) of the  Securities  Exchange  Act of 1934,  as amended  (the
"Exchange Act"), requires the Company's officers and directors,  and persons who
own more than 10% of a registered class of the Company's equity  securities,  to
file  reports of  ownership  and changes in ownership  with the  Securities  and
Exchange Commission.  Officers,  directors and greater than 10% stockholders are
required by regulations of the Securities and Exchange Commission to furnish the
Company  with  copies of all such  reports.  Based  solely on its  review of the
copies of such reports received by it, or written  representations  from certain
reporting  persons that no reports were required for those persons,  the Company
believes that, during the period from January 1, 1997, to December 31, 1997, all
filing requirements applicable to its officers,  directors, and greater than 10%
stockholders  were  complied  with,  except  that  Morton  Salkind  and  Stephan
Carlquist  each filed a Form 3 late and Sam Oolie and Jay Haft each filed a Form
5 late.

ITEM 13.    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

   In October 1990, the Company's Board of Directors  authorized the issuance of
warrants to acquire  420,000  shares of common stock to each of Messrs.  McCloy,
Parrella and Oolie and Ms. Lebovics,  exercisable through September 30, 1994, at
$.375 per share,  being the market  price of the  Company's  common stock on the
date of such  authorization,  based upon each such person's commitment to extend
his or her personal  guarantee  on a joint and several  basis with the others in
support  of  the  Company's  attempt  to  secure  bank  or  other  institutional
financing,  the amount of which to be covered by the guarantee  would not exceed
$350,000.  No firm  commitment  for any such  financing  has been secured by the
Company and at present no such financing is being sought.  However, each of such
persons'  commitment  to  furnish  said  guarantee  continues  in full force and
effect.

   In 1989, the Company established a joint venture with Environmental  Research
Information, Inc., ("ERI") to jointly develop, manufacture and sell (i) products
intended  for  use  solely  in  the  process  of  electric   power   generation,
transmission and distribution and which reduce noise and/or vibration  resulting
from such process, (ii) personal quieting products sold directly to the electric
utility industry and (iii) products that reduce noise and/or vibration emanating
from fans and fan systems (collectively,  "Power and Fan Products"). In 1991, in
connection with the termination of this joint venture, the Company agreed, among
other things,  during the period ending  February  1996, to make payments to ERI
equal to (i) 4.5% of the  Company's  sales of Power  and Fan  Products  and (ii)
23.75% of fees derived by the Company from its license of Power and Fan Products
technology,  subject to an overall  maximum of $4,500,000.  Michael J. Parrella,
President  of  the  Company,  was  Chairman  of  ERI at the  time  of  both  the
establishment and termination of the joint venture and owns approximately 12% of
the outstanding capital of ERI. In addition, Jay M. Haft, Co-Chairman, and Chief
Executive Officer of the Company,  shares investment  control over an additional
24% of the outstanding  capital of ERI. The Company believes that the respective
terms  of  both  the  establishment  of the  joint  venture  with  ERI  and  its
termination  were comparable to those that could have been negotiated with other
persons or entities. During the fiscal year ended December 31, 1996, the Company
was not required to make any such payments to ERI under these agreements.

   In 1993, the Company entered into three Marketing  Agreements with QuietPower
Systems,  Inc.  ("QSI")  (until  March 2, 1994,  "Active  Acoustical  Solutions,
Inc."),  a company which is 33% owned by ERI and 2% owned by Mr. Haft. Under the
terms of one of these Marketing  Agreements,  QSI has undertaken to use its best
efforts to seek research and  development  funding for the Company from electric
and natural gas utilities for applications of the Company's  technology to their
industries.  In exchange for this undertaking,  the Company has issued a warrant
to QSI to purchase  750,000 shares of Common Stock at $3.00 per share.  The last
sale price for the Common Stock reported on the NASDAQ National Market System on
May 15, 1993,  the date of the  Marketing  Agreement,  was $2.9375.  The warrant
becomes  exercisable  as to  specific  portions of the total  750,000  shares of
Common Stock upon the occurrence of defined events  relating to QSI's efforts to
obtain such funding for the Company. When such defined events occur, the Company
will  record a charge  for the  amount by which the  market  price of the Common
Stock on such  date  exceeds  $3.00  per  share,  if any.  The  warrant  remains
exercisable  as to each such portion from the  occurrence  of the defined  event
through  October 13,  1998.  As of December  31,  1994,  contingencies  had been
removed  against  525,000  warrants  resulting  in a  1993  non-cash  charge  of
$120,250.  This Marketing  Agreement also grants to QSI a non-exclusive right to
market the  Company's  products that are or will be designed and sold for use in
or with equipment used by electric and/or natural gas utilities for non-retrofit
applications in North America.  QSI is entitled to receive a sales commission on
any sales to a customer of such  products for which QSI is a procuring  cause in
obtaining  the first order from such  customer.  In the case of sales to utility
company customers, the commission is 6% of the revenues received by the Company.
On sales to original equipment manufacturers for utilities, the commission is 6%
on the gross  revenue NCT  receives on such sales from the customer in the first
year, 4% in the second year, 2% in the third year and 1% in the fourth year, and
 .5% in any future years after the fourth year. QSI is also entitled to receive a
5% commission on any research and development funding it obtains for NCT, and on
any license  fees it obtains for the Company  from the license of the  Company's
technology.  The  initial  term of  this  Agreement  is  three  years  renewable
automatically  thereafter on a  year-to-year  basis unless a party elects not to
renew.

   Under the  terms of the  second of the  three  Marketing  Agreements,  QSI is
granted a non-exclusive  right to market the Company's products that are or will
be  designed  and sold for use in or with  feeder  bowls  throughout  the world,
excluding Scandinavia and Italy. Under this Marketing Agreement, QSI is entitled
to  receive  commissions  similar  to those  payable  to end  user and  original
equipment  manufacturer  customers  described  above.  QSI is also  entitled  to
receive  the same 5%  commission  described  above on research  and  development
funding and  technology  licenses which it obtains for the Company in the feeder
bowl area.  The initial  term of this  Marketing  Agreement  is three years with
subsequent automatic one-year renewals unless a party elects not to renew.

   Under the terms of the third Marketing Agreement, QSI is granted an exclusive
right to market the Company's products that are or will be designed and sold for
use in or with  equipment  used by electric  and/or  natural gas  utilities  for
retrofit  applications  in North  America.  QSI is  entitled  to receive a sales
commission  on any sales to a customer of such  products  equal to 129% of QSI's
marketing  expenses  attributable  to the marketing of the products in question,
which expenses are to be deemed to be the lesser of QSI's actual expenses or 35%
of the revenues  received by the Company from the sale of such products.  QSI is
also  entitled to receive a 5% commission  on research and  development  funding
similar  to  that  described  above.  QSI's  exclusive  rights  continue  for an
indefinite  term  provided it meets  certain  performance  criteria  relating to
marketing efforts during the first two years following  product  availability in
commercial  quantity and minimum levels of product sales in subsequent years. In
the event QSI's rights  become  non-exclusive,  depending  on the  circumstances
causing  such change,  the initial term then becomes  either three or five years
from the date of this Marketing  Agreement,  with subsequent  one-year automatic
renewals in each instance  unless  either party elects not to renew.  During the
fiscal year ended  December  31,  1996,  the Company was not required to pay any
commissions to QSI under any of these Marketing Agreements.

   The Company has also  entered into a Teaming  Agreement  with QSI under which
each  party  agrees  to  be  responsible  for  certain  activities  relating  to
transformer  quieting system development  projects to be undertaken with utility
companies.  Under this Teaming Agreement,  QSI is entitled to receive 19% of the
amounts to be received from participating  utilities and the Company is entitled
to receive 81%. During the fiscal year ended December 31, 1996, the Company made
no payments to QSI for project management services.

   In March 1995,  the Company  entered into a Master  Agreement  with QSI under
which QSI was granted an exclusive  worldwide  license under certain NCT patents
and technical  information to market, sell and distribute  transformer  quieting
products,  turbine  quieting  products and certain other products in the utility
industry. Under the Master Agreement, QSI is to fund development of the products
by the Company and the Company is to manufacture the products.  However, QSI may
obtain the right to manufacture the products under certain circumstances include
NCT's  failure to develop the products or the failure of the parties to agree on
ertain  development  matters.  In consideration of the rights granted under the
Master  Agreement,  QSI is to pay  the  Company  a  royalty  of 6% of the  gross
revenues  received  from the sale of the products and 50% of the gross  revenues
received from  sublicensing the rights granted to QSI under the Master Agreement
after QSI has recouped 150% of the costs  incurred by QSI in the  development of
the products in question.  The Company is obligated to pay similar  royalties to
QSI on its sale of the products and the  licensing of rights  covered  under the
Master  Agreement  outside the  utility  industry  and from sales and  licensing
within the  utility  industry  in the Far East.  In  addition  to the  foregoing
royalties, QSI is to pay an exclusivity fee to the Company of $750,000; $250,000
of which QSI paid to the  Company in June 1994.  The balance is payable in equal
monthly  installments of $16,667 beginning in April 1995. QSI's exclusive rights
become  non-exclusive  with  respect  to all  products  if it  fails  to pay any
installment  of the  exclusivity  fee when due and QSI loses  such  rights  with
respect  to any  given  product  in the  event it fails to make any  development
funding payment applicable to that product.  The Master Agreement supersedes all
other agreements  relating to the products  covered under the Master  Agreement,
including those agreements between the Company and QSI described above.

   Immediately following the execution to the Master Agreement,  the Company and
QSI entered into a letter agreement  providing for the termination of the Master
Agreement at the Company's election if QSI did not pay approximately $500,000 in
payables then owed to the Company by May 15, 1995.

   In April 1995,  the Company and QSI entered  into  another  letter  agreement
under  which QSI  agreed to  forfeit  and  surrender  the five year  warrant  to
purchase  750,000  shares of the Company's  common stock issued to QSI under the
first Marketing Agreement described above. In addition,  the $500,000 balance of
the  exclusivity  fee  provided  for under the Master  Agreement  was reduced to
$250,000 to be paid in 30 monthly installments of $8,333 each and the payment of
the  indebtedness  to be  paid  under  the  letter  agreement  described  in the
preceding  paragraph  was revised to be the earlier of May 15, 1996, or the date
of closing of a financing of QSI in an amount exceeding $1.5 million,  whichever
first occurs.  Such  indebtedness  is to be evidenced by a promissory  note, non
payment  of which is to  constitute  an event of  termination  under the  Master
Agreement.

   On May 21, 1996,  the Company and QSI entered into another  letter  agreement
extending the time by which the payments from QSI to the Company under the April
1995  letter  agreement  described  above were to be made.  Under the letter the
payment of certain  arrearages in the payment of the  exclusivity  fee was to be
made not later than June 15, 1996, with the balance  continuing to be payable by
monthly payments of $8,333 and as provided in the May 1995 letter agreement.  In
addition the payment of the other indebtedness owed by QSI to the Company was to
be paid by a payment  of $25,000 at the time QSI  obtained  certain  anticipated
financing with the balance paid by monthly payments of $15,000 each.  Default in
QSI's timely payment of any of the amounts  specified in the May 21, 1996 letter
agreement was to cause the immediate termination of the Master Agreement and all
rights granted to QSI thereunder.

   On April 9, 1997, the Company and QSI entered into another  letter  agreement
revising  the payment  schedule  set forth in the May 21, 1996 letter  agreement
applicable to the payment of the  indebtedness  owed to the Company by QSI other
than the unpaid portion of the exclusivity fee. Under the revised schedule,  the
full amount of such indebtedness is to be paid by an initial payment of $125,000
on or before April 21, 1997,  and a second  payment of $200,000 upon the closing
of a proposed  financing  in June 1997 or on January  1, 1998,  whichever  first
occurs.  The  Company is also  entitled  to receive  15% of any other  financing
obtained  by QSI in the interim as well as interest at the rate of 10% per annum
on the  unpaid  amount  of such  indebtedness  from  July 1,  1997.  The  letter
agreement also provides for the continuation of QSI's payment of the exclusivity
fee in accordance  with the earlier letter  agreements as well as the payment of
$11,108 by April 21, 1997,  for headset  products  sold by the Company to QSI in
1996.  In the event of a default in QSI's  timely  payment of any of the amounts
specified  in the April 9, 1997 letter  agreement,  the Company has the right to
cause the  termination  of the Master  Agreement  and all rights  granted by QSI
thereunder upon 10 days notice of termination to QSI.

     As of February 27, 1998, QSI has paid all  installments due and payable for
the  exclusivity  fee and owes the Company  $150,000 which was due on January 1,
1998 and is fully  reserved,  and other than as described  above,  owes no other
amounts to the Company.

   The Company believes that the terms of its agreements with QSI are comparable
to those that it could have negotiated with other persons or entities.

                            INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders of
  Noise Cancellation Technologies, Inc.

     We have  audited  the  accompanying  consolidated  balance  sheets of Noise
Cancellation  Technologies,  Inc. and  subsidiaries  as at December 31, 1996 and
1997,  and the related  consolidated  statements  of  operations,  stockholders'
equity  and cash  flows for each of the  years in the  three-year  period  ended
December 31, 1997.  These  financial  statements are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial  statements  based on our audits.  We did not audit the 1995, 1996 and
1997  financial  statements  of the Company's  two foreign  subsidiaries.  These
subsidiaries  accounted for revenues of approximately  $1,200,000,  $407,000 and
$67,000 for the years ended December 31, 1995, 1996 and 1997, respectively,  and
assets of  approximately  $586,000,  $515,000 and $301,000 at December 31, 1995,
1996 and 1997,  respectively.  These  statements  were audited by other auditors
whose reports have been  furnished to us, one of which  contained a reference to
dependence  on the parent for  continued  financial  support.  Our opinion,
insofar as it relates  to the  amounts  included  for these  entities,  is based
solely on the reports of the other auditors.

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

     In our opinion,  based on our audits and the reports of the other auditors,
the  financial  statements  enumerated  above  present  fairly,  in all material
respects,   the   consolidated   financial   position   of  Noise   Cancellation
Technologies,  Inc.  and  subsidiaries  as at December 31, 1996 and 1997 and the
consolidated  results of their operations and their  consolidated cash flows for
each of the years in the three-year period ended December 31, 1997 in conformity
with generally accepted accounting principles.

     The  accompanying  consolidated  financial  statements  have been  prepared
assuming that the Company will continue as a going concern. As discussed in Note
1 to the  financial  statements,  the  Company  has not  been  able to  generate
sufficient  cash flow from  operating  activities to sustain its  operations and
since it has incurred net losses since  inception,  it has been and continues to
be dependent on equity  financing and joint venture  arrangements to support its
business  efforts.  These factors raise  substantial  doubt about its ability to
continue as a going concern.  Management's  plans in regard to these matters are
also  described  in  Note  1.  The  financial  statements  do  not  include  any
adjustments that might result from the outcome of this uncertainty.

                             NOISE CANCELLATION TECHNOLOGIES, INC.
                               NOTES TO THE FINANCIAL STATEMENTS

1. Background:

      Noise Cancellation  Technologies,  Inc. ("NCT" or the "Company")  designs,
develops,  licenses, produces and distributes electronic systems for Active Wave
Management including systems that electronically reduce noise and vibration. The
Company's  systems are  designed for  integration  into a wide range of products
serving major markets in the transportation, manufacturing, commercial, consumer
products  and  communications  industries.  The  Company  has  begun  commercial
application  of its  technology  through  a number  of  product  lines,  with 70
products currently being sold, including NoiseBuster(R)  communications headsets
and NoiseBuster  Extreme!(TM) consumer headsets,  Gekko(TM) flat speakers,  flat
panel transducers ("FPT(TM)"), ClearSpeech(TM),  microphones, speakers and other
products,   adaptive  speech  filters  ("ASF"),   the   ProActive(TM)   line  of
industrial/commercial  active  noise  reduction  ("ANR")  headsets,  an aviation
headset for  pilots,  an  industrial  muffler or  "silencer"  for use with large
vacuums and blowers,  quieting  headsets  for patient use in magnetic  resonance
imaging ("MRI") machines, and an aircraft cabin quieting system.

   The  technology  supporting  the Company's  electronic  systems was developed
using technology  maintained under various patents (the "Chaplin  Patents") held
by  Chaplin-Patents  Holding Co.,  Inc.  ("CPH") as well as patented  technology
acquired or developed by the Company.  CPH, formerly a joint venture with Active
Noise Vibration  Technologies,  Inc.  ("ANVT"),  was established to maintain and
defend these patent rights.  The former joint venture agreement  relating to the
Chaplin  Patents  required  that the Company  only  license or share the related
technology  with entities who are  affiliates of the Company.  As a result,  the
Company  established various joint ventures and formed other strategic alliances
(see Note 3) to further  develop  the  technology  and  electronic  systems and
components  based on the  Chaplin  Patents,  to  develop  such  technology  into
commercial  applications,  to integrate  the  electronic  systems into  existing
products and to distribute  such systems and products  into various  industrial,
commercial and consumer markets.

   The  Company  has  incurred  substantial  losses  from  operations  since its
inception,  which  have  been  recurring  and  amounted  to $93.5  million  on a
cumulative  basis  through  December  31, 1997 and has working  capital of $11.7
million  at  December  31,  1997.  These  losses,  which  include  the costs for
development of products for commercial use, have been funded  primarily from the
sale of common stock and preferred stock,  including the exercise of warrants or
options  to  purchase  common  stock,  and  by  technology  licensing  fees  and
engineering  and  development  funds  received  from  joint  venture  and  other
strategic  partners.  As discussed in Note 3,  agreements with joint venture and
other strategic  partners  generally  require that a portion of the initial cash
flows,  if  any,  generated  by the  ventures  or the  alliances  be  paid  on a
preferential basis to the Company's  co-venturers until the technology licensing
fees and  engineering  and  development  funds  provided  to the  venture or the
Company are recovered.

     Cash and cash  equivalents  amounted to $12.6 million at December 31, 1997.
Management  believes  that  currently  available  funds may not be sufficient to
sustain the Company for the next 12 months. Such funds consist of available cash
and cash from the  exercise of warrants and  options,  the funding  derived from
technology   licensing  fees,   royalties  and  product  sales  and  engineering
development  revenue.  Reducing operating expenses and capital expenditure alone
may not be sufficient and  continuation as a going concern is dependent upon the
level of realization of funding from technology licensing fees and royalties and
product  sales  and  engineering  and  development  revenue,  all of  which  are
presently uncertain.  In the event that technology licensing fees, royalties and
product  sales,  and  engineering  and  development  revenue are not realized as
planned,  then management  believes additional working capital financing must be
obtained. There is no assurance any such financing is or would become available.

     There can be no  assurance  that  funding  will be provided  by  technology
license  fees,  royalties  and product  sales and  engineering  and  development
revenue.  In that event,  the Company would have to  substantially  cut back its
level of  operations.  These  reductions  could  have an  adverse  effect on the
Company's  relations  with its  strategic  partners and  customers.  Uncertainty
exists with  respect to the adequacy of current  funds to support the  Company's
activities  until positive cash flow from  operations can be achieved,  and with
respect to the  availability  of financing  from other  sources to fund any cash
deficiencies (see Note 6 with respect to recent financing).

     The accompanying  financial statements have been prepared assuming that the
Company will  continue as a going  concern,  which  contemplates  continuity  of
operations,  realization  of  assets  and  satisfaction  of  liabilities  in the
ordinary  course of business.  The propriety of using the going concern basis is
dependent  upon,  among  other  things,  the  achievement  of future  profitable
operations and the ability to generate  sufficient cash from operations,  public
and private  financings and other funding sources to meet its  obligations.  The
uncertainties  described in the preceding  paragraphs raise substantial doubt at
December 31, 1997 about the  Company's  ability to continue as a going  concern.
The accompanying financial statements do not include any adjustments relating to
the  recoverability  of the carrying  amount of recorded assets or the amount of
liabilities that might result from the outcome of these uncertainties.

2.  Summary of Significant Accounting Policies:

Consolidation:

   The financial statements include the accounts of the Company and its majority
owned subsidiaries. All material inter-company transactions and account balances
have been eliminated in consolidation.

   Unconsolidated  affiliates  include  joint  ventures  and other  entities not
controlled  by the  Company,  but over which the Company  maintains  significant
influence  and in which the  Company's  ownership  interest is 50% or less.  The
Company's  investments in these entities are accounted for on the equity method.
When the Company's  equity in cumulative  losses  exceeds its investment and the
Company has no  obligation  or intention  to fund such  additional  losses,  the
Company  suspends  applying the equity method (see Note 3). The Company will not
be able to record any equity in income with respect to an entity until its share
of future profits is sufficient to recover any  cumulative  losses that have not
previously been recorded.

Revenue Recognition:

Products Sales:

   Revenue is recognized as the product is shipped.

Engineering and development services:

   Revenue from  engineering and development  contracts is recognized and billed
as the services are performed.  However,  revenue from certain  engineering  and
development  contracts  are  recognized  as  services  are  performed  under the
percentage of completion method after 10% of the total estimated costs have been
incurred.  Under the percentage of completion method,  revenues and gross profit
are  recognized as work is performed  based on the  relationship  between actual
costs incurred and total  estimated  costs at completion.  Estimated  losses are
recorded when identified.

   Revenues  recorded  under the  percentage  of completion  method  amounted to
$249,000,  $9,000 and zero for the years ended December 31, 1995, 1996 and 1997,
respectively.

Technology Licensing Fees:

     Technology licensing fees paid by joint venturers, co-venturers,  strategic
partners or other  licensees which are  nonrefundable,  are recognized in income
upon execution of the license  agreement or upon  completion of any  performance
criteria specified within the agreement. See Note 3, with respect to the license
fee recorded by the Company in connection with Ultra  Electronics,  Ltd. in 1995
and New Transducers, Ltd. in 1997.

Advertising:

     Advertising  costs are  expensed  as  incurred.  Expense  for  years  ended
December  31,  1995,  1996  and 1997 was $0.6  million,  $0.5  million  and $0.5
million, respectively.

Cash and cash equivalents:

     The  Company   considers  all  money  market  accounts  and  highly  liquid
investments  with  original  maturities  of three  months or less at the time of
purchase  (principally comprise high quality investments in commercial paper) to
be cash equivalents.


Inventories:

   Inventories are stated at the lower of cost (first in, first out) or market.

     With regard to the Company's  assessment of the realizability of inventory,
the Company periodically conducts a complete physical inventory, and reviews the
movement of inventory  on an item by item basis to determine  the value of items
which are slow moving.  After  considering  the  potential for near term product
engineering changes and/or technological obsolescence and current realizability,
the Company determines the current need for inventory  reserves.  After applying
the above noted  measurement  criteria at December  31,  1996,  and December 31,
1997,  the Company  determined  that a reserve of $0.3 million and $0.5 million,
respectively, was adequate.

Property and Equipment:

   Property and equipment are stated at cost and depreciation is recorded on the
straight-line  method over the estimated useful lives of the respective  assets.
Leasehold  improvements  are amortized over the shorter of their useful lives or
the related lease term.


<PAGE>

Patent Rights:

   Patent  rights are stated at cost and are  amortized on a straight line basis
over  the  remaining  life  of  each  patent  (ranging  from  1  to  15  years).
Amortization  expense was $0.4 million,  $0.4 million and $0.3 million for 1995,
1996 and 1997, respectively.  Accumulated amortization was $1.5 million and $1.8
at December 31, 1996 and 1997, respectively.

     It is the  Company's  policy to review its  individual  patents when events
have occurred which could impair the valuation on any such patent.

Foreign currency translation:

   The financial  statements  for the United  Kingdom  operations are translated
into U.S.  dollars at year-end  exchange  rates for assets and  liabilities  and
weighted  average  exchange  rates for  revenues  and  expenses.  The effects of
foreign  currency  translation  adjustments  are  included  as  a  component  of
stockholders'  equity  and gains and  losses  resulting  from  foreign  currency
transactions are included in income and have not been material.

Loss per common share:

     The Company adopted Statement of Financial  Accounting  Standards  ("SFAS")
No.  128,  Earnings  Per  Share," in the year ended  December  31,  1997 and has
retroactively   applied   the  effects   thereof  for  all  periods   presented.
Accordingly,  the presentation of per share information includes calculations of
basic  and  dilutive  loss  per  share.  The  impact  on the per  share  amounts
previously reported (primary and fully diluted) was not significant. The effects
of potential common shares such as warrants,  options, and convertible preferred
stock has not been included, as the effect would be antidilutive.  (See Notes 3,
6 and 7.)

Concentrations of Credit Risk:

     Financial   instruments   which   potentially   subject   the   Company  to
concentration of credit risk consist of cash and cash  equivalents.  The Company
considers all money market accounts and investments with original  maturities of
three months or less at the time of purchase to be cash equivalents. The Company
primarily holds its cash and cash equivalents in two banks and commercial paper.
Deposits in excess of federally  insured  limits were $12.4  million at December
31, 1997.  The Company  sells its  products  and services to original  equipment
manufacturers,  distributors and end users in various industries  worldwide.  As
shown below, the Company's five largest  customers  accounted for  approximately
71% of revenues during 1997 and 59% of accounts receivable at December 31, 1997.
The Company does not require  collateral or other  security to support  customer
receivables.

     The Company regularly assesses the realizability of its accounts receivable
and  performs  a  detailed  analysis  of  its  aged  accounts  receivable.  When
quantifying the  realizability  of accounts  receivable,  the Company takes into
consideration  the value of past due receivables and the  collectibility of such
receivables, based on credit worthiness.

Use of Estimates:

   The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual results could differ from those estimates.

Stock-Based Compensation:

     During  1996,  the  Company  adopted  Statement  of  Financial   Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS No. 123). The
provisions  of SFAS No. 123 allow the Company to either  expense  the  estimated
fair value of stock  options and warrants or to continue to follow the intrinsic
value  method  set forth in APB  Opinion  25,  "Accounting  for Stock  Issued to
Employees"  (APB 25) but disclose the pro forma effects on net income (loss) had
the fair value of the options or warrants been expensed. The Company has elected
to continue to apply APB 25 in  accounting  for its  employee  stock  option and
warrant incentive plans. Please refer to Note 7 for further information.

Recently issued accounting pronouncements:

     In, June 1997, the Financial  Accounting  Standards Board issued Statements
of Financial  Accounting  Standards No. 129,  "Disclosure of  Information  about
Capital  Structure",  No.  130,  "Reporting  Comprehensive  Income" and No. 131,
"Disclosures  about  Segments of an  Enterprise  and Related  Information".  The
Company  has not yet  determined  whether the above  pronouncements  will have a
significant effect on the information presented in the financial statements.

3.  Joint Ventures and Other Strategic Alliances:

   The  following is a summary of certain of the  Company's  joint  ventures and
other strategic alliances as of December 31, 1997.

   The Company and certain of its majority-owned  subsidiaries have entered into
agreements to establish joint ventures and other strategic  alliances related to
the  design,  development,   manufacture,  marketing  and  distribution  of  its
electronic  systems and  products  containing  such  systems.  These  agreements
generally  provide that the Company license  technology and contribute a nominal
amount of initial capital and that the other parties provide  substantially  all
of the  funding to  support  the  venture  or  alliance.  This  support  funding
generally  includes  amounts  paid or  services  rendered  for  engineering  and
development.  In exchange for this funding, the other party generally receives a
preference in the distribution of cash and/or profits from the joint ventures or
royalties from these alliances until such time that the support funding (plus an
"interest"  factor in some instances) is recovered.  At December 31, 1997, there
were no  preferred  distributions  due to joint  venture  partners  from  future
profits of the joint ventures.

   Technology  licensing fees and engineering and development fees paid by joint
ventures to the Company are recorded as income since there is no recourse to the
Company  for  these  amounts  or any  commitment  by the  Company  to  fund  the
obligations of the venture.

   When the Company's  share of cumulative  losses equals its investment and the
Company has no  obligation  or intention  to fund such  additional  losses,  the
Company  suspends  applying  the  equity  method.  The  aggregate  amount of the
Company's  share of losses in these joint  ventures  in excess of the  Company's
investments  which has not been  recorded  was zero at December  31,  1997.  The
Company  will not be able to record  any  equity in income  with  respect  to an
entity until its share of future profits is sufficient to recover any cumulative
losses that have not previously been recorded.

   Certain of the joint  ventures  will be suppliers to the Company and to other
of the joint ventures and will transfer  products to the related  entities based
upon pricing  formulas  established in the agreements.  The formula is generally
based upon fully  burdened  cost, as defined in the  agreements,  plus a nominal
profit.

  Total  revenues  recorded by the Company  relating to the joint  ventures and
alliances,  or their principals,  for technology licensing fees, engineering and
development services and product sales were as follows:

   Outlined  below is a summary of the nature and terms of selected  ventures or
alliances:

Joint Ventures

     OnActive  Technologies,  L.L.C.  ("OAT")  is a  limited  liability  company
currently owned 42.5% by Applied Acoustic Research, L.L.C. ("AAR"), 42.5% by the
Company  and 15.0% by Hoover  Universal,  Inc.,  a wholly  owned  subsidiary  of
Johnson Controls,  Inc.("JCI") (collectively,  the "Members") under an Operating
Agreement concluded in December, 1995 and amended in May, 1996. OAT will design,
develop,  manufacture,  market,  distribute  and  sell  flat  panel  transducers
("FPT(TM))  and  related  components  for use in audio  applications  and  audio
systems installed in ground based vehicles. Initial capital contributions by the
Company and AAR were  nominal  and no Member is required to make any  additional
contribution  to OAT. In May,  1996,  JCI  acquired a $1.5  million,  15% equity
interest in OAT and acquired  exclusive  rights in the  automotive OEM market to
certain of the Company's and AAR's related  patents for a total of $1.5 million,
which was paid  50/50 to the  Company  and AAR.  In  connection  therewith,  the
Company  recorded a license fee of $750,000  during the year ended  December 31,
1996. The Operating  Agreement provides that services and subcontracts  provided
to OAT by the Members are to be  compensated by OAT at 115% of the Members fully
burdened cost.  However,  during 1996,  administrative  services required by OAT
were  provided by the Company and not charged to OAT.  During 1996 such services
were nominal.  As of December 31, 1995 the Company  recognized $80,000 of income
relating to its share of 1995 profit in OAT. As of December 31, 1996 the Company
reversed  the $80,000 of income  which  related to its share of the 1996 loss in
OAT.  In  consideration  for  certain  marketing  services to be provided by the
Company and Oxford  International,  Ltd. (Oxford), an affiliate of AAR, OnActive
will pay the Company and Oxford two percent  (2%) each of the revenues or thirty
percent (30%) each of the gross margin  (whichever is less) received by OnActive
from the sale of Top Down Surround  Sound(TM) ("TDSS") systems and the licensing
of TDSS technology to certain original equipment manufacturers.

Other Strategic Alliances:

   Ultra Electronics Ltd.  (formerly Dowty Maritime  Limited)  ("Ultra") and the
Company  entered  into a teaming  agreement  in May 1993 to  collaborate  on the
design,  manufacture and  installation of products to reduce noise in the cabins
of various types of aircraft.  In  accordance  with the  agreement,  the Company
provided  informational  and  technical  assistance  relating  to  the  aircraft
quieting  system and Ultra  reimbursed  the  Company  for  expenses  incurred in
connection  with such  assistance.  Ultra was  responsible for the marketing and
sales  of  the  products.  The  Company  was to  supply  Ultra  with  electronic
components  required for the aircraft  quieting system, at a defined cost, to be
paid by Ultra.

   In March  1995,  the Company and Ultra  amended  the  teaming  agreement  and
concluded  a  licensing  and  royalty  agreement  for $2.6  million and a future
royalty of 1-1/2 % of sales commencing in 1998.  Under the agreement,  Ultra has
also  acquired  the  Company's  active  aircraft   quieting  business  based  in
Cambridge,  England, leased a portion of the Cambridge facility and has employed
certain of the Company's employees.

   Accordingly,  the Company recorded $2.6 million as a technology licensing fee
relating to the net amount received from above noted amended  teaming  agreement
and the licensing and royalty agreement in the first quarter of 1995.

   New  Transducers  Ltd.(NXT),  a wholly owned  subsidiary  of Verity Group PLC
("Verity")  and the Company  executed a cross  licensing  agreement  (the "Cross
License")  on March 28,  1997.  Under  terms of the Cross  License,  the Company
licensed patents and patents pending which relate to FPT(TM)  technology to NXT,
and NXT licensed patents and patents pending which relate to parallel technology
to the Company. In consideration of the license,  during the first quarter 1997,
NCT recorded a $3.0 million license fee receivable from NXT as well as royalties
on future  licensing and product  revenue.  The Company also executed a security
deed (the "Security Deed") in favor of NXT granting NXT a conditional assignment
in the patents and patents  pending  licensed to NXT under the Cross  License in
the event a default  in a certain  payment to be made by the  Company  under the
Cross License continued beyond fifteen days.  Concurrent with the Cross License,
the Company and Verity  executed  agreements  granting each an option for a four
year period  commencing on March 28, 1998, to acquire a specified  amount of the
common stock of the other subject to certain  conditions and restrictions.  With
respect to the  Company's  option to Verity (the "Verity  Option"),  3.8 million
shares of common stock  (approximately  3.4% of the then issued and  outstanding
common stock) of the Company are covered by such option and the Company executed
a registration rights agreement (the "Registration  Rights Agreement")  covering
such shares. Five million ordinary shares (approximately 2.0% of the then issued
and outstanding  ordinary shares) of Verity are covered by the option granted by
Verity to the Company. The exercise price under each option is the fair value of
a share of the applicable  stock on March 28, 1997, the date of grant.  On April
15, 1997,  Verity,  NXT and the Company  executed  several  agreements and other
documents (the "New  Agreements")  terminating  the Cross License,  the Security
Deed, the Verity Option and the Registration Rights Agreement and replacing them
with new agreements  (respectively  the "New Cross  License",  the "New Security
Deed", the "New Verity Option" and the "New Registration Rights Agreement"). The
material  changes effected by the New Agreements were the inclusion of Verity as
a party along with its wholly owned  subsidiary NXT;  providing that the license
fee  payable  to NCT  could be paid in  ordinary  shares of  Verity  stock;  and
reducing  the  exercise  price  under the option  granted to Verity to  purchase
shares of the Company's common stock to $0.30 per share. The subject license fee
was  paid  to the  Company  in  ordinary  shares  of  Verity  stock  which  were
subsequently sold by the Company.  On September 27, 1997, Verity, NXT, NCT Audio
Products,  Inc. ("NCT Audio") and the Company  executed  several  agreements and
other documents, terminating the New Cross License and the New Security Deed and
replacing them with new agreements  (respectively,  the "Cross License Agreement
dated  September  27, 1997" and the "Master  License  Agreement").  The material
changes  effected by the most recent  agreements were an expansion of the fields
of use  applicable  to the  exclusive  licenses  granted to Verity  and NXT,  an
increase in the  royalties  payable on future  licensing  and product  revenues,
cancellation  of the New  Security  Deed  covering  the patents  licensed by the
Company,  and the  acceleration  of the date on which the parties  can  exercise
their respective stock purchase option to September 27, 1997.

6.  Common Stock:

Private Placements:

   On November 8, 1995 the Company  entered into a stock purchase  agreement for
the sale of 4.8 million  shares of its common stock in a private  placement to a
foreign  investor  in  consideration  for $3.3  million in net  proceeds  to the
Company.  The closing of the  transaction  occurred on November  14,  1995.  The
purchaser  of the  common  stock was  subject to  certain  resale  and  transfer
restrictions  including those under Regulation S of the United States Securities
Act of 1933, as amended.

   The Company completed a private placement of 2.0 million shares of its common
stock on August 4, 1995  receiving  approximately  $0.7 million in net proceeds.
The  purchaser  of the common  stock was subject to certain  resale and transfer
restrictions  including those under  Regulation D of the Securities Act of 1933,
as amended. As provided for in the Stock Purchase Agreement,  within nine months
of the closing date, the Company was obligated to file a registration  statement
with the Securities and Exchange  Commission  covering the  registration  of the
shares for resale by the purchaser.

   On March 28, 1996, the Company sold 2.0 million shares of its common stock in
a second private placement with the investor in the private placement  described
in the  preceding  paragraph  that  provided net proceeds to the Company of $0.7
million  under  terms  and  conditions  substantially  the  same as those of the
earlier private  placement.  A registration  statement  covering the 4.0 million
shares of the  Company's  common  stock issued in  connection  with this private
placement  and  the  one  described  in the  preceding  paragraph  was  declared
effective by the Commission on September 3, 1996.

   On April 10, 1996, the Company sold an additional  1,000,000  shares,  in the
aggregate,  of its common stock in a private placement with three  institutional
investors   that   provided  net  proceeds  to  the  Company  of  $0.3  million.
Contemporaneously,  the  Company  sold  secured  convertible  term  notes in the
aggregate principal amount of $1.2 million to those institutional  investors and
granted  them  each an option to  purchase  an  aggregate  of $3.45  million  of
additional  shares of the Company's common stock. The per share conversion price
under the notes and the exercise  price under the options are equal to the price
received by the Company for the sale of such 1,000,000 shares subject to certain
adjustments.

   On  August  13,  1996,  the three  institutional  investors  converted  their
secured,  convertible  term notes and  exercised  their  options  in full.  As a
result,  the Company issued 13,403,130  shares, in the aggregate,  of its common
stock to such  investors,  received  $3.45  million  in cash,  and  effected  by
conversion  to its  common  stock the  payment  of the notes  together  with the
accrued interest thereon.

   On August 29, 1996,  the Company sold 1.8 million  shares of its common stock
to the same foreign investor which purchased 4.8 million shares of the Company's
common  stock in  November,  1995.  The  Company  received  $0.9  million of net
proceeds.  The purchaser is subject to certain resale and transfer  restrictions
with respect to these shares.

     Between January 15, 1997 and March 25, 1997, the Company issued and sold an
aggregate  amount  of  $3.4  million  of  non-voting  subordinated   convertible
debentures (the "Debentures") in a private placement pursuant to Regulation S of
the Securities Act of 1933, as amended, (the "Securities Act") to five unrelated
investors (the  "Investors")  through  multiple dealers (the "First Quarter 1997
Financing")  from which the Company  realized $3.2 million of net proceeds.  The
Debentures  were to mature between  January 15, 2000 and March 25, 2000 and earn
8% interest per annum,  payable quarterly in either cash or the Company's common
stock at the  Company's  sole  option.  Subject to certain  common  stock resale
restrictions,  the Investors, at their discretion,  had the right to convert the
principal  due on the  Debentures  into the  Company's  common stock at any time
after  the 45th day  following  the  date of the sale of the  Debentures  to the
Investors.  In the  event of such a  conversion,  the  conversion  price was the
lesser of 85% of the  closing  bid price of the  Company's  common  stock on the
closing date of the  Debentures'  sale or between 75% to 60%  (depending  on the
Investor  and other  conditions)  of the average  closing bid price for the five
trading days  immediately  preceding  the  conversion.  To provide for the above
noted conversion and interest  payment options,  the Company reserved 15 million
shares of the Company's common stock for issuance upon such conversion.  Subject
to certain  conditions,  the Company also had the right to require the Investors
to convert all or part of the Debentures  under the above noted conversion price
conditions  after  February  15, 1998.  As of June 6, 1997,  the  Investors  had
converted  all $3.4 million of the  Debentures  into 16.5 million  shares of the
Company's  common  stock.  At the Company's  election,  interest due through the
conversion  dates  of  the  Debentures  was  paid  through  the  issuance  of an
additional 0.2 million shares of the Company's common stock. In conjunction with
the  Debentures,  the  Company  granted a warrant to purchase  75,000  shares of
common stock to one  investor.  During the year ended  December  31,  1997,  the
Company valued this warrant,  using the  Black-Scholes  pricing model at $34,000
which was  expensed as debt  discount.  The Company has  recorded a $1.4 million
non-cash  interest expense  attributable to the conversions of the Debentures in
the first and second quarters of 1997 as an adjustment  during the fourt quarter
of 1997.  If the shares were issued in lieu of debt at the  respective  issuance
dates of the debt,  supplementary  basic and  diluted net loss per share for the
year ended December 31, 1997 would have been a loss of $0.08 per share.

   On June 19, 1997 the  stockholders  approved an  amendment  to the  Company's
Restated  Certificate  of  Incorporation  to increase the  authorized  number of
shares of common  stock  from 140  million  shares to 185  million  shares.  The
Company has reserved 3.9 million shares of such  additional  shares for issuance
upon the  exercise  of the New  Verity  Option  and 2.6  million  shares of such
additional  shares for issuance  upon the  exercise of options  granted or to be
granted  and  future  grants  of   restricted   stock  awards  under  the  Noise
Cancellation Technologies, Inc. Stock Incentive Plan (the "1992 Plan").

   On July 30, 1997 the Company sold 2.9 million  shares,  in the aggregate,  of
its  common  stock at a price of $0.175 per share in the July 30,  1997  Private
Placement that provided net proceeds to the Company of $0.5 million.

     On September 4, 1997,  the Company  transferred  $5,000 cash and all of the
business  and assets of its Audio  Products  Division as then  conducted  by the
Company and as reflected  on the business  books and records of the Company to a
newly incorporated  company, NCT Audio, in consideration for 5,867 shares of NCT
Audio common stock  whereupon NCT Audio became a wholly owned  subsidiary of the
Company.  The Company also granted NCT Audio an exclusive worldwide license with
respect to all of the  Company's  relevant  patented and  unpatented  technology
relating to FPT(TM) and FPT(TM) based audio speaker products for all markets for
such products  excluding  (a) markets  licensed to or reserved by Verity and NXT
under the  Company's  cross  licensing  agreements  with Verity and NXT, (b) the
ground based  vehicle  market  licensed to OAT, (c) all markets for hearing aids
and other  hearing  enhancing  or  assisting  devices,  and (d) all  markets for
headsets,  headphones and other products performing functions  substantially the
same as those performed by such products in  consideration  for a license fee of
$3.0  million  (eliminated  in  consolidation)  to be  paid  when  proceeds  are
available from the sale of NCT Audio common stock and on-going future  royalties
payable by NCT Audio to the Company as provided in such  license  agreement.  In
addition, the Company agreed to transfer all of its rights and obligations under
its cross licensing  agreements with Verity and NXT to NCT Audio and to transfer
the  Company's  interest  in OAT to NCT  Audio.  Between  October  10,  1997 and
December 4, 1997 NCT Audio issued  2,145  shares of its common stock  (including
533 shares issued to Verity) for an aggregate  purchase price of $4.0 million in
a private placement  pursuant to Regulation D under the Securities Act (the "NCT
Audio Financing"). NCT Audio has not met certain conditions regarding the filing
of a registration  statement for NCT Audio common stock. As such, holders of NCT
Audio common  stock have a right to convert  their NCT Audio common stock into a
sufficient  number of  restricted  shares  of NCT  common  stock to equal  their
original  cash  investment  in NCT Audio,  plus a 20% discount to market.  As of
February 27, 1998, no NCT Audio shareholder has exercised their right to convert
NCT Audio common stock into NCT common stock under the terms noted above.

     Between  October 28, 1997 and December 11, 1997, the Company entered into a
series of  subscription  agreements (the  "Subscription  Agreements") to sell an
aggregate  amount of $13.3 million of Series C Convertible  Preferred Stock (the
"Preferred  Stock") in a private  placement,  pursuant  to  Regulation  D of the
Securities Act, to 32 unrelated  accredited  investors  through two dealers (the
"1997  Preferred Stock Private  Placement").  The total Preferred Stock Offering
was completed on December 11, 1997. The aggregate net proceeds to the Company of
the 1997 Preferred Stock Private Placement were $11.9 million. Each share of the
Preferred  Stock has a par  value of $.10 per  share  and a stated  value of one
thousand  dollars ($1,000) with an accretion rate of four percent (4%) per annum
on the stated value.  Each share of Preferred  Stock is  convertible  into fully
paid and  nonassessable  shares of the Company's Common Stock subject to certain
limitations.  Under the terms of the  Subscription  Agreements  the  Company  is
required  to  exercise  its  best  efforts  to  file  a  registration  statement
("Registration  Statement")  on Form S-3  covering  the  resale of all shares of
Common Stock of the Company issuable upon conversion of the Preferred Stock then
outstanding within sixty (60) days after the first Closing of the 1997 Preferred
Stock Private  Placement.  The shares of Preferred Stock become convertible into
shares of Common  Stock at any time  commencing  after  the  earlier  of (i) the
effective date of the Registration Statement; or (ii) ninety (90) days after the
date of filing of the Registration  Statement.  Each share of Preferred Stock is
convertible into a number of shares of Common Stock of the Company as determined
in accordance with the Conversion  Formula as set forth in the agreement using a
conversion  price  equal to the  lesser of (x) 120% of the five (5) day  average
closing bid price of Common Stock  immediately  prior to the closing date of the
Preferred  Stock  being  converted  or (y) 20%  below  the five (5) day  average
closing  bid price of Common  Stock  immediately  prior to the  conversion  date
thereof.  See  Item 7 -  "Management's  Discussion  and  Analysis  of  Financial
Condition  and  Results of  Operations  -  Overview"  for a  description  of the
Conversion Formula.

   The  conversion  terms of the  Preferred  Stock also provide that in no event
shall the average  closing bid price  referred to in the  Conversion  Formula be
less than  $0.625 per share and in no event shall the  Company be  obligated  to
issue more than 26.0  million  shares of its Common  Stock in the  aggregate  in
connection with the conversion of the Preferred Stock. Accordingly, 26.0 million
shares of Common Stock which could be issuable upon  conversion of the Preferred
Stock are included in the offering to which the  prospectus  relates.  Under the
terms of the Subscription  Agreements the Company may be subject to a penalty if
the Registration  Statement is not declared  effective within one hundred twenty
(120) days after the first closing of any incremental portion of the offering of
Preferred  Stock,  such  penalty  to be in an  amount  equal to one and one half
percent (1.5%) per month of the aggregate  amount of Preferred Stock sold in the
offering  up to a maximum of ten percent  (10%) of such  aggregate  amount.  The
Subscription Agreements also provide that for a period commencing on the date of
the signing of the Subscription Agreements and ending ninety (90) days after the
closing of the offering the Company will be prohibited  from issuing any debt or
equity  securities  other than Preferred Stock, and that the Corporation will be
required  to make  certain  payments  in the  event  of its  failure  to  effect
conversion  in a timely  manner or in the event it fails to  reserve  sufficient
authorized  but  unissued  Common  Stock for  issuance  upon  conversion  of the
Preferred Stock.

     The Securities and Exchange  Commission  (the "SEC") has taken the position
that when preferred  stock is  convertible to common stock at a conversion  rate
that is the  lower of a rate  fixed at  issuance  or a fixed  discount  from the
common stock market price at the time of conversion, the discounted amount is an
assured incremental yield, the "beneficial conversion feature", to the preferred
shareholders  and should be accounted  for as an embedded  dividend to preferred
shareholders.  As such,  this dividend was  recognized in the earnings per share
calculation.

Stock subscription receivable:

   The  $0.4  million  stock  subscription   receivable  at  December  31,  1997
represents  a receivable  of $0.1 million due from a director  which was paid in
1998,  and a $0.3  million  receivable  from the escrow  agent for the NCT Audio
financing which has not yet been paid.

Shares reserved for common stock options and warrants:

   At December 31, 1997  aggregate  shares  reserved  for issuance  under common
stock option plans and warrants  amounted to 17.7 million shares of which common
stock options and warrants for 18.6 million shares are outstanding  (see Note 7)
and 16.2 million shares are exercisable.


7.  Common Stock Options and Warrants:

     The Company  applies APB 25 in accounting  for its various  employee  stock
option incentive plans and warrants and,  accordingly,  recognizes  compensation
expense as the  difference,  if any,  between the market price of the underlying
common  stock and the  exercise  price of the  option on the date of grant.  The
effect of  applying  SFAS No.  123 on 1995,  1996 and 1997 pro forma net loss as
stated above is not  necessarily  representative  of the effects on reported net
loss for future periods due to, among other  factors,  (i) the vesting period of
the stock options and (ii) the fair value of  additional  stock option grants in
future periods. If compensation expense for the Company's stock option plans and
warrants had been determined  based on the fair value of the options or warrants
at the grant date for awards under the plans in accordance  with the methodology
prescribed  under  SFAS No.  123,  the  Company's  net loss would have been $5.8
million,  $12.8 million and $15.8  million,  or $(.07),  $(0.13) and $(0.14) per
share in 1995,  1996 and 1997,  respectively.  The fair value of the options and
warrants  granted in 1995,  1996 and 1997 are estimated in the range of $0.44 to
$1.25, $0.48 to $0.58 and $0.16 to $4.07 per share, respectively, on the date of
grant using the  Black-Scholes  option-pricing  model  utilizing  the  following
assumptions:  dividend yield 0%,  volatility of 1.040,  1.225 and 1.289 in 1995,
1996 and 1997,  respectively,  risk free interest rates in the range of 5.63% to
7.84%, 5.05% to 6.50% and 5.79% to 6.63% for 1995, 1996 and 1997,  respectively,
and expected life of 3 years. The weighted average fair value of options granted
during 1995, 1996 and 1997 are estimated in the range of $0.37 to $0.66,  $0.49,
and  $0.13 to  $0.58  per  share,  respectively  also  using  the  Black-Scholes
option-pricing model.

Stock Options:

   The  Company's  1987 Stock  Option Plan (the "1987  Plan")  provides  for the
granting of up to  4,000,000  shares of common stock as either  incentive  stock
options or nonstatutory stock options. Options to purchase shares may be granted
under the 1987 Plan to persons who, in the case of incentive stock options,  are
full-time employees  (including  officers and directors) of the Company;  or, in
the case of nonstatutory stock options, are employees or non-employee  directors
of the Company.  The exercise  price of all  incentive  stock options must be at
least equal to the fair market value of such shares on the date of the grant and
may be exercisable  over a ten-year  period.  The exercise price and duration of

the number of shares of the Company's Common Stock included in the 1992 Plan. At
the time of such  stockholder  approval,  if the market  value of the  Company's
stock exceeds the exercise price of the subject options,  the Company will incur
a non-cash  charge to earnings equal to the spread between the exercise price of
the option and market price, times the number of options involved.

8.  Related Parties:

     Environmental Research Information, Inc.

   In 1989, the Company established a joint venture with Environmental  Research
Information, Inc., ("ERI") to jointly develop, manufacture and sell (i) products
intended  for  use  solely  in  the  process  of  electric   power   generation,
transmission and distribution and which reduce noise and/or vibration  resulting
from such process, (ii) personal quieting products sold directly to the electric
utility industry and (iii) products that reduce noise and/or vibration emanating
from fans and fan systems (collectively,  "Power and Fan Products"). In 1991, in
connection with the termination of this joint venture, the Company agreed, among
other things,  during the period ending  February  1996, to make payments to ERI
equal to (i) 4.5% of the  Company's  sales of Power  and Fan  Products  and (ii)
23.75% of fees derived by the Company from its license of Power and Fan Products
technology,  subject to an overall  maximum of $4,500,000.  Michael J. Parrella,
President  of  the  Company,  was  Chairman  of  ERI at the  time  of  both  the
establishment and termination of the joint venture and owns approximately 12% of
the outstanding capital of ERI. In addition,  Jay M. Haft, Chairman of the Board
of Directors of the Company, shares investment control over an additional 24% of
the outstanding  capital of ERI. During the fiscal year ended December 31, 1996,
the  Company  was not  required  to make any such  payments  to ERI under  these
agreements.

     Quiet Power Systems, Inc.

   In 1993, the Company entered into three Marketing  Agreements with QuietPower
Systems,  Inc.  ("QSI")  (until  March 2, 1994,  "Active  Acoustical  Solutions,
Inc."),  a company which is 33% owned by ERI and 2% owned by Mr. Haft. Under the
terms of one of these Marketing  Agreements,  QSI has undertaken to use its best
efforts to seek research and  development  funding for the Company from electric
and natural gas utilities for applications of the Company's  technology to their
industries.  In exchange for this undertaking,  the Company has issued a warrant
to QSI to purchase  750,000 shares of Common Stock at $3.00 per share.  The last
sale price for the Common Stock reported on the NASDAQ National Market System on
May 15, 1993,  the date of the  Marketing  Agreement,  was $2.9375.  The warrant
becomes  exercisable  as to  specific  portions of the total  750,000  shares of
Common Stock upon the occurrence of defined events  relating to QSI's efforts to
obtain such funding for the Company. When such defined events occur, the Company
will  record a charge  for the  amount by which the  market  price of the Common
Stock on such  date  exceeds  $3.00  per  share,  if any.  The  warrant  remains
exercisable  as to each such portion from the  occurrence  of the defined  event
through  October 13,  1998.  As of December  31,  1993,  contingencies  had been
removed  against  525,000  warrants  resulting  in a  1993  non-cash  charge  of
$120,250.  This Marketing  Agreement also grants to QSI a non-exclusive right to
market the  Company's  products that are or will be designed and sold for use in
or with equipment used by electric and/or natural gas utilities for non-retrofit
applications in North America.  QSI is entitled to receive a sales commission on
any sales to a customer of such  products for which QSI is a procuring  cause in
obtaining  the first order from such  customer.  In the case of sales to utility
company customers, the commission is 6% of the revenues received by the Company.
On sales to original equipment manufacturers for utilities, the commission is 6%
on the gross  revenue NCT  receives on such sales from the customer in the first
year, 4% in the second year, 2% in the third year and 1% in the fourth year, and
 .5% in any future years after the fourth year. QSI is also entitled to receive a
5% commission on any research and development funding it obtains for NCT, and on
any license  fees it obtains for the Company  from the license of the  Company's
technology.  The  initial  term of  this  Agreement  is  three  years  renewable
automatically  thereafter on a  year-to-year  basis unless a party elects not to
renew.

   Under the  terms of the  second of the  three  Marketing  Agreements,  QSI is
granted a non-exclusive  right to market the Company's products that are or will
be  designed  and sold for use in or with  feeder  bowls  throughout  the world,
excluding Scandinavia and Italy. Under this Marketing Agreement, QSI is entitled
to  receive  commissions  similar  to those  payable  to end  user and  original
equipment  manufacturer  customers  described  above.  QSI is also  entitled  to
receive  the same 5%  commission  described  above on research  and  development
funding and  technology  licenses which it obtains for the Company in the feeder
bowl area.  The initial  term of this  Marketing  Agreement  is three years with
subsequent automatic one-year renewals unless a party elects not to renew.

   Under the terms of the third Marketing Agreement, QSI is granted an exclusive
right to market the Company's products that are or will be designed and sold for
use in or with  equipment  used by electric  and/or  natural gas  utilities  for
retrofit  applications  in North  America.  QSI is  entitled  to receive a sales
commission  on any sales to a customer of such  products  equal to 129% of QSI's
marketing  expenses  attributable  to the marketing of the products in question,
which expenses are to be deemed to be the lesser of QSI's actual expenses or 35%
of the revenues  received by the Company from the sale of such products.  QSI is
also  entitled to receive a 5% commission  on research and  development  funding
similar  to  that  described  above.  QSI's  exclusive  rights  continue  for an
indefinite  term  provided it meets  certain  performance  criteria  relating to
marketing efforts during the first two years following  product  availability in
commercial  quantity and minimum levels of product sales in subsequent years. In
the event QSI's rights  become  non-exclusive,  depending  on the  circumstances
causing  such change,  the initial term then becomes  either three or five years
from the date of this Marketing  Agreement,  with subsequent  one-year automatic
renewals in each instance unless either party elects not to renew.

   For the years  ended  December  31,  1995,  1996 and 1997 the Company was not
required to pay any commissions to QSI under any of these Marketing Agreements.

   The Company has also  entered into a Teaming  Agreement  with QSI under which
each  party  agrees  to  be  responsible  for  certain  activities  relating  to
transformer  quieting system development  projects to be undertaken with utility
companies.  Under this Teaming Agreement,  QSI is entitled to receive 19% of the
amounts to be received from participating  utilities and the Company is entitled
to receive 81%.  During the fiscal year ended  December 31, 1995,  1996 and 1997
no payments were required to be made to QSI.

   In March 1995,  the Company  entered into a Master  Agreement  with QSI under
which QSI was granted an exclusive  worldwide  license under certain NCT patents
and technical  information to market, sell and distribute  transformer  quieting
products,  turbine  quieting  products and certain other products in the utility
industry. Under the Master Agreement, QSI is to fund development of the products
by the Company and the Company is to manufacture the products.  However, QSI may
obtain the right to manufacture the products under certain circumstances include
NCT's  failure to develop the products or the failure of the parties to agree on
certain  development  matters.  In consideration of the rights granted under the
Master  Agreement,  QSI is to pay  the  Company  a  royalty  of 6% of the  gross
revenues  received  from the sale of the products and 50% of the gross  revenues
received from  sublicensing the rights granted to QSI under the Master Agreement
after QSI has recouped 150% of the costs  incurred by QSI in the  development of
the products in question.  The Company is obligated to pay similar  royalties to
QSI on its sale of the products and the  licensing of rights  covered  under the
Master  Agreement  outside the  utility  industry  and from sales and  licensing
within the  utility  industry  in the Far East.  In  addition  to the  foregoing
royalties, QSI is to pay an exclusivity fee to the Company of $750,000; $250,000
of which QSI paid to the  Company in June 1994.  The balance is payable in equal
monthly  installments of $16,667 beginning in April 1995. QSI's exclusive rights
become  non-exclusive  with  respect  to all  products  if it  fails  to pay any
installment  of the  exclusivity  fee when due and QSI loses  such  rights  with
respect  to any  given  product  in the  event it fails to make any  development
funding payment applicable to that product.  The Master Agreement supersedes all
other agreements  relating to the products  covered under the Master  Agreement,
including those agreements between the Company and QSI described above.

   Immediately following the execution to the Master Agreement,  the Company and
QSI entered into a letter agreement  providing for the termination of the Master
Agreement at the Company's election if QSI did not pay approximately $500,000 in
payables then owed to the Company by May 15, 1995.

   In April 1995,  the Company and QSI entered  into  another  letter  agreement
under  which QSI  agreed to  forfeit  and  surrender  the five year  warrant  to
purchase  750,000  shares of the Company's  common stock issued to QSI under the
first Marketing Agreement described above. In addition,  the $500,000 balance of
the  exclusivity  fee  provided  for under the Master  Agreement  was reduced to
$250,000 to be paid in 30 monthly installments of $8,333 each and the payment of
the  indebtedness  to be  paid  under  the  letter  agreement  described  in the
preceding  paragraph  was revised to be the earlier of May 15, 1996, or the date
of closing of a financing of QSI in an amount exceeding $1.5 million,  whichever
first occurs.  Such  indebtedness  is to be evidenced by a promissory  note, non
payment  of which is to  constitute  an event of  termination  under the  Master
Agreement.

   On May 21, 1996,  the Company and QSI entered into another  letter  agreement
extending the time by which the payments from QSI to the Company under the April
1995  letter  agreement  described  above were to be made.  Under the letter the
payment of certain  arrearages in the payment of the  exclusivity  fee was to be
made not later than June 15, 1996, with the balance  continuing to be payable by
monthly payments of $8,333 and as provided in the May 1995 letter agreement.  In
addition the payment of the other indebtedness owed by QSI to the Company was to
be paid by a payment  of $25,000 at the time QSI  obtained  certain  anticipated
financing with the balance paid by monthly payments of $15,000 each.  Default in
QSI's timely payment of any of the amounts  specified in the May 21, 1996 letter
agreement was to cause the immediate termination of the Master Agreement and all
rights granted to QSI thereunder.

   On April 9, 1997, the Company and QSI entered into another  letter  agreement
revising  the payment  schedule  set forth in the May 21, 1996 letter  agreement
applicable to the payment of the  indebtedness  owed to the Company by QSI other
than the unpaid portion of the exclusivity fee. Under the revised schedule,  the
full amount of such indebtedness is to be paid by an initial payment of $125,000
on or before April 21, 1997,  and a second  payment of $200,000 upon the closing
of a proposed  financing  in June 1997 or on January  1, 1998,  whichever  first
occurs.  The  Company is also  entitled  to receive  15% of any other  financing
obtained  by QSI in the interim as well as interest at the rate of 10% per annum
on the  unpaid  amount  of such  indebtedness  from  July 1,  1997.  The  letter
agreement also provides for the continuation of QSI's payment of the exclusivity
fee in accordance  with the earlier letter  agreements as well as the payment of
$11,108 by April 21, 1997,  for headset  products  sold by the Company to QSI in
1996.  In the event of a default in QSI's  timely  payment of any of the amounts
specified  in the April 9, 1997 letter  agreement,  the Company has the right to
cause the  termination  of the Master  Agreement  and all rights  granted by QSI
thereunder upon 10 days notice of termination to QSI.

     As of February 27, 1998, QSI has paid all  installments due and payable for
the  exclusivity  fee and owes the Company  $150,000 which was due on January 1,
1998 and is fully  reserved,  and other than as described  above,  owes no other
amounts to the Company.

Other Parties

   During 1995, 1996 and 1997 the Company  purchased $0.5 million,  $0.6 million
and $0.7 million respectively,  of products from its various manufacturing joint
venture entities.


9. Income Taxes:

   The  Company  provides  for income  taxes in  accordance  with  Statement  of
Financial   Accounting   Standards  No.  109,   Accounting   for  Income  Taxes.
Accordingly,  deferred tax assets and  liabilities are established for temporary
differences between tax and financial reporting bases of assets and liabilities.
A valuation allowance is established when the Company determines that it is more
likely than not that a deferred  tax asset will not be realized.  The  Company's
temporary  differences  primarily result from depreciation  related to machinery
and equipment,  compensation expense related to warrants,  options and reserves.
The  adoption  of  the  aforementioned  accounting  standard  had no  effect  on
previously reported results of operations.

   At  December  31,  1997,   the  Company  had  available  net  operating  loss
carryforwards of approximately $76.9 million and research and development credit
carryforwards  of $1.3 million for federal  income tax purposes  which expire as
follows:

(1)Includes  approximately $4.1 million net operating loss relating to NCT Audio
   Products, Inc.

   The Company's ability to utilize its net operating loss  carryforwards may be
subject to an annual  limitation.  The difference between the statutory tax rate
of 34% and the Company's  effective tax rate of 0% is due to the increase in the
valuation  allowance  of $1.4  million , $3.3  million and $3.0 million in 1995,
1996 and 1997, respectively.

   The types of temporary  differences that give rise to significant portions of
the  deferred  tax  assets  and the  federal  and  state  tax  effect  of  those
differences as well as federal net operating  loss and research and  development
credit at December 31, 1996 and 1997 were as follows:

10.  Litigation:

   On or about June 15, 1995,  Guido  Valerio  filed suit against the Company in
the  Tribunal  of Milan,  Milan,  Italy.  The suit  requests  the Court to award
judgment in favor of Mr.  Valerio as follows:  (i)  establish and declare that a
proposed independent sales representation  agreement submitted to Mr. Valerio by
the Company and signed by Mr.  Valerio but not  executed by the Company was made
and entered  into  between Mr.  Valerio and the Company on June 30,  1992;  (ii)
declare that the Company is guilty of breach of contract and that the  purported
agreement  was  terminated  by  unilateral  and  illegitimate  withdrawal by the
company;  (iii) order the Company to pay Mr. Valerio $30,000 for certain amounts
alleged to be owing to Mr. Valerio by the Company; (iv) order the Company to pay
commissions  to which Mr.  Valerio  would have been  entitled if the Company had
followed up on certain alleged  contacts made by Mr. Valerio for an amount to be
assessed by technicians and  accountants  from the Court Advisory  Service;  (v)
order the  Company  to pay  damages  for the harm and  losses  sustained  by Mr.
Valerio in terms of loss of  earnings  and  failure to receive due payment in an
amount such as shall be determined following preliminary  investigations and the
assessment to be made by experts and accountants from the Court Advisory Service
and in any event no less than 3 billion Lire ($18.9 million); and (vi) order the
Company to pay  damages for the harm done to Mr.  Valerio's  image for an amount
such as the judge shall deem  equitable and in case for no less than 500 million
Lire  ($3.1  million).  The  Company  retained  an  Italian  law firm as special
litigation counsel to the Company in its defense of this suit. On March 6, 1996,
the  Company,  through  its  Italian  counsel,  filed a brief of reply  with the
Tribunal of Milan  setting  forth the  Company's  position  that:  (i) the Civil
Tribunal of Milan is not the proper venue for the suit, (ii) Mr. Valerio's claim
is  groundless  since the parties  never  entered into an  agreement,  and (iii)
because Mr.  Valerio is not enrolled in the official  Register of Agents,  under
applicable  Italian law Mr. Valerio is not entitled to any  compensation for his
alleged  activities.  A preliminary  hearing before the Tribunal was held on May
30, 1996,  certain pretrial  discovery has been completed and a hearing before a
Discovery  Judge was held on October 17, 1996.  Submissions of the parties final
pleadings  were to be  made in  connection  with  the  next  hearing  which  was
scheduled for April 3, 1997. On April 3, 1997,  the  Discovery  Judge  postponed
this hearing to May 19, 1998, due to reorganization  of all proceedings  pending
before the Tribunal of Milan.  Management  is of the opinion that the lawsuit is
without  merit and will  contest it  vigorously.  In the opinion of  management,
after consultation with outside counsel, resolution of this suit should not have
a material  adverse  effect on the Company's  financial  position or operations.
However,  in the event  that the  lawsuit  does  result in a  substantial  final
judgment against the Company,  said judgment could have a severe material effect
on quarterly or annual operating results.

     On September 16, 1997, Ally Capital Corporation ("Ally") filed suit against
the Company, John J. McCloy II, Michael J. Parrella, Jay M. Haft and Alistair J.
Keith in the United States  District Court for the District of Connecticut  (the
"District Court"). The complaint was not served on the Company until January 16,
1998,  and has yet to be served on the  individual  defendants.  The  individual
defendants  are current and former  officers and  directors of the Company.  The
complaint  alleges three (3) causes of action  arising out of an agreement  (the
"Asset Purchase  Agreement")  which the Company entered into with another entity
known as Active Noise and  Vibration  Technologies,  Inc.  ("ANVT")  whereby the
Company agreed to acquire ANVT's patented and unpatented  intellectual property,
the rights and obligations  under a defined list of agreements  between ANVT and
twenty-one  (21) other  parties (the "Listed  Parties")  relating to existing or
potential  joint  ventures,  licensing  and other  business  relationships,  and
certain items of office and laboratory equipment.  For these assets, the Company
paid ANVT two hundred thousand ($200,000.00) dollars and issued ANVT two million
(2,000,000)  shares of the Company's common stock. The Asset Purchase  Agreement
also provided ANVT with the right to certain contingent payments,  to the extent
the Company generated certain levels of revenue from joint venture, licensing or
other contractual  relationships with any of the Listed Parties.  Plaintiff Ally
is an  unsecured  creditor  of ANVT  and is not a party  to the  Asset  Purchase
Agreement;  however,  Ally asserts an interest to part of the consideration paid
ANVT by virtue of an escrow agreement  between ANVT and the escrow agent for the
benefit of ANVT's  secured  and  unsecured  creditors.  Ally  purports to allege
claims of fraud,  negligent  misrepresentation and a claim under the Connecticut
Unfair Trade Practice Act based upon purported representations made to ANVT, not
Ally. Thus, it is alleged that the Company  misrepresented to ANVT the Company's
financial  condition,  the number of shares it could  issue and the value of the
contingent payment rights under the Asset Purchase Agreement. In connection with
the claims, Ally seeks compensatory damages in excess of one million two hundred
thousand ($1,200,000.00)  dollars,  punitive damages and attorney fees. On March
4, 1998,  the  Company  served its motion to dismiss the  complaint  pursuant to
Federal Rule of Civil Procedure 12. The basis for the motion  include:  that the
summons and  complaint  were not served for more than one hundred  twenty  (120)
days  after the  complaint  was filed,  in  violation  of Federal  Rule of Civil
Procedure  4; that Ally lacks  standing to bring its claims as they are based on
purported representations made by the Company to ANVT, not Ally; that the claims
are legally insufficient under Connecticut law; and that plaintiff has failed to
join  necessary  parties,  ANVT and the escrow agent.  As no discovery has taken
place,  the  Company is unable to assess the  likelihood  of an adverse  result.
Management, however, believes it has meritorious defenses and intends a vigorous
defense of this  lawsuit.  However,  in the event this  lawsuit does result in a
substantial  final  judgment  against the Company,  said  judgment  could have a
severe material effect on quarterly or annual operating results.


11.  Commitments and Contingencies:

   The Company is obligated for minimum annual rentals (net of sublease  income)
under  operating  leases for  offices,  warehouse  space and  laboratory  space,
expiring through April 2007 with various renewal options, as follows:

   Rent expense (net of sublease income) was $0.8 million, $0.6 million and $0.4
million for each of the three  years ended  December  31,  1995,  1996 and 1997,
respectively.  During 1995, rent expense was paid, in part, through the issuance
of common stock (see Note 6).

   In April,  1996,  the Company  established  the Noise  Cancellation  Employee
Benefit Plan (the "Benefit Plan") which provides, among other coverage,  certain
health care benefits to employees  and directors of the Company's  United States
operations.  The Company  administers  this modified  self insured  Benefit Plan
through a  commercial  third  party  administrative  health care  provider.  The
Company's maximum aggregate benefit exposure in each Benefit Plan fiscal year is
limited to $1.0 million while combined individual and family benefit exposure in
each Benefit Plan fiscal year is limited to $35,000. Benefit claims in excess of
the above mentioned individual or the maximum aggregate stop loss are covered by
a commercial third party insurance  provider to which the Company pays a nominal
premium for the subject stop loss coverage.  The Company  records  benefit claim
expense in the period in which the benefit claim is incurred. As of February 27,

                     RIGHTS OF SERIES C CONVERTIBLE PREFERRED STOCK OF
                           NOISE CANCELLATION TECHNOLOGIES, INC.


      Noise  Cancellation  Technologies,   Inc.,  a  corporation  organized  and
existing  under the General  Corporation  Law of the State of  Delaware  (herein
called the "Corporation"),

      DOES HEREBY CERTIFY:

      That,  pursuant to authority  conferred upon the Board of Directors of the
Corporation by the Restated Certificate of Incorporation of the Corporation, and
pursuant to the  provisions  of Section 151 of Title 8 of the  Delaware  Code of
1953, as amended, said Board of Directors, at a meeting duly held on October 22,
1997,  adopted  a  resolution  providing  for the  issuance  of a series  of ten
thousand (10,000) shares of Series C Convertible  Preferred Stock, and providing
for the powers, designations,  preferences and relative, participating, optional
or other special rights and qualifications, limitations or restrictions thereof,
which resolution is as follows:

            RESOLVED,  that pursuant to the authority  expressly  granted to and
      vested in the Board of Directors of the  Corporation  by the provisions of
      Article  IV  of  the  Restated   Certificate  of   Incorporation   of  the
      Corporation,  this  Board of  Directors  hereby  creates  a series  of the
      Preferred Stock of the Corporation  with par value of $0.10 per share (the
      "Preferred  Stock")  to  consist of ten  thousand  (10,000)  shares of the
      10,000,000 authorized shares of Preferred Stock, which the Corporation now
      has  authority  to issue,  and this Board of  Directors  hereby  fixes the
      powers, designations, preferences and relative, participating, optional or
      other  special  rights and  qualifications,  limitations  or  restrictions
      thereof  of the  shares  of  such  series  (in  addition  to  the  powers,
      designations,  preferences and relative, participating,  optional or other
      special rights and  qualifications,  limitations or restrictions  thereof,
      set  forth  in  Article  IV  of  the  Certificate  of  Incorporation   not
      inconsistent with the terms of this resolution and which are applicable to
      the Preferred Stock) as follows:

      1.    Designation.

            The  designation  of said series of Preferred  Stock created by this
Resolution shall be Series C Convertible  Preferred Stock (herein called "Series
C Convertible Preferred Stock").



<PAGE>


      2.    Par Value, Stated Value and Accretion Rate.

   Each share of Series C Convertible  Preferred Stock shall have a par value of
$0.10,  and a stated value (face amount) of One Thousand  Dollars  ($1,000) (the
"Stated  Value"),  with an accretion  rate of four percent (4%) per annum on the
Stated Value for the purposes and on the terms set forth herein.

      3.    Dividends.

            The Series C Convertible Preferred Stock will bear no dividends, and
the holders of the Series C Convertible Preferred Stock shall not be entitled to
the receipt of dividends on the Series C Convertible Preferred Stock.

      4.    Liquidation Preference.

   a.  In the  event  of  any  liquidation,  dissolution  or  winding-up  of the
Corporation,  either voluntary or involuntary (a "Liquidation"),  the holders of
record of shares of the Series C  Convertible  Preferred  Stock then  issued and
outstanding  (the  "Series C  Holders")  shall be entitled to be paid out of the
assets  of the  Corporation  available  for  distribution  to its  shareholders,
whether from capital,  surplus or earnings,  before any payment shall be made to
the holders of shares of the Common  Stock of the  Corporation,  par value $0.01
per share,  (the "Common  Stock") or upon any other series of Preferred Stock of
the  Corporation,  an amount per share  equal to the sum of (i) one  hundred ten
percent (110%) of the Stated Value and (ii) an amount equal to four percent (4%)
of the Stated Value multiplied by the fraction N/365,  where N equals the number
of days elapsed  since the issue date of Series C Convertible  Preferred  Stock.
If,  upon any  Liquidation  of the  Corporation,  the assets of the  Corporation
available for distribution to its shareholders  shall be insufficient to pay the
Series C Holders and the holders of any other series of  Preferred  Stock with a
liquidation  preference  equal to the  liquidation  preference  of the  Series C
Convertible Preferred Stock the full amounts to which they shall respectively be
entitled,  the Series C Holders and the holders of any other series of Preferred
Stock with  liquidation  preference  equal to the liquidation  preference of the
Series C  Convertible  Preferred  Stock  shall  receive all of the assets of the
Corporation  available  for  distribution  and each such Series C Holder and the
holders of any other series of  Preferred  Stock with a  liquidation  preference
equal to the liquidation  preference of the Series C Convertible Preferred Stock
shall share ratably in any  distribution in accordance with the amounts due such
shareholders.  After payment shall have been made to the Series C Holders of the
full amount to which they shall be entitled, as aforesaid,  the Series C Holders
shall be entitled to no further  distributions thereon and the holders of shares
of the  Common  Stock  and of  shares  of  any  other  series  of  stock  of the
Corporation shall be entitled to share, according to their respective rights and
preferences,   in  all  remaining  assets  of  the  Corporation   available  for
distribution to its shareholders.

            b. A merger or  consolidation  of the  Corporation  with or into any
other corporation, or a sale, lease, exchange, or transfer of all or any part of
the assets of the  Corporation  which shall not in fact result in a  Liquidation
(in whole or in part) of the Corporation  and the  distribution of its assets to
its  shareholders  shall  not  be  deemed  to  be  a  voluntary  or  involuntary
Liquidation (in whole or in part) of the Corporation.

      5.    Redemption and Repurchase.

            a. The Corporation,  at the option of its Board of Directors,  shall
have the right at any time to redeem the Series C Convertible Preferred Stock in
whole  (and  not in  part)  at a  redemption  price  equal to the sum of (i) one
hundred ten percent  (110%) of the Stated Value and (ii) an amount equal to four
percent  (4%) of the Stated Value  multiplied  by the  fraction  N/365,  where N
equals  the  number  of  days  elapsed  from  the  issue  date of the  Series  C
Convertible  Preferred  Stock to the date of  redemption  fixed by the  Board of
Directors.  Notice of such  redemption and the redemption date shall be given to
the  Series C Holders  by mail or in such  other  manner as may be  provided  by
resolution of the Board of Directors,  not more than six months nor less than 30
days prior to the date fixed for such redemption. Any notice given by mail shall
be deemed given when mailed by registered or certified mail postage prepaid,  or
when delivered  personally to the Series C Holders at their respective addresses
as the same shall then appear on the books of the Corporation.  If any notice of
redemption shall have been given as aforesaid and if on or before the redemption
date the funds  necessary for such  redemption  shall have been set aside by the
Corporation,  separate and apart from its other funds, in trust for the pro rata
benefit of the Holders of the shares so called for  redemption,  then,  from and
after the redemption date,  notwithstanding  that any certificates for shares so
called for redemption  shall not have been  surrendered  for  cancellation,  the
shares  represented  thereby  shall  not be  deemed  outstanding,  the  right to
accretion  thereon shall cease to accrue from and after the redemption  date and
all  rights of the  Series C Holders  of the  shares  so called  for  redemption
(including, but not limited to, rights of conversion) shall forthwith, after the
redemption  date,  cease and terminate,  excepting only the right to receive the
redemption  price therefor,  but without  interest or other  additional  payment
except as set forth in the first sentence of this Section 5; provided,  however,
that the conversion  rights of the Series C Holders shall continue from the date
of notice of redemption  until the close of business on the redemption date. Any
moneys so set aside by the  Corporation  and  unclaimed  at the end of six years
from the redemption  date shall revert to the general funds of the  Corporation,
after which reversion of such funds shall become contributions to the capital of
the Corporation and the Series C Holders shall have no further claim or right to
such funds.  If any shares of the Series C  Convertible  Preferred  Stock of the
Corporation shall have been redeemed,  purchased or otherwise  reacquired by the
Corporation  in  accordance  with the  laws of the  State  of  Delaware  or this
Certificate, the Board of Directors may, without any action by the stockholders,
insofar as is permissible  under the laws of the State of Delaware,  at any time
or from time to time,  eliminate all or part of such shares from the  authorized
number of shares of Series C Convertible Preferred Stock of the Corporation.

      6.    Conversion of Series C Convertible Preferred Stock.

            a. Rights to Convert.  Each share of Series C Convertible  Preferred
Stock shall be convertible, on the Conversion Dates and at the Conversion Prices
set forth  below,  into  fully  paid and  nonassessable  shares of Common  Stock
(sometimes referred to herein as "Conversion  Shares") subject to the limitation
set forth below in paragraph g of this Section 6.

            b.  Mechanics  of  Conversion.  Each  Series C Holder who desires to
convert  shares of Series C  Convertible  Preferred  Stock into shares of Common
Stock shall provide notice ("Conversion  Notice") via telecopy  (facsimile) on a
business day, during business hours in Linthicum,  Maryland, to the Corporation,
and  a  facsimile  of  the  Conversion   Notice  shall  be  transmitted  to  the
Corporation's  Transfer  Agent at the same time as  transmission  is made to the
Corporation.  On the same day, the original Conversion Notice shall be delivered
to the Corporation but the certificate or certificates representing the Series C
Convertible Preferred Stock for which conversion is elected,  shall be delivered
to the Transfer Agent by international  courier, duly endorsed. The later of the
date upon which the Corporation  receives the original  Conversion Notice or the
date the Transfer  Agent  receives the  Certificates  representing  the Series C
Convertible Preferred Stock for which conversion is elected,  shall be a "Notice
Date".

                  Upon receipt by the  Corporation  of a Conversion  Notice,  as
provided above, the Corporation  shall  immediately send to the Series C Holder,
via telecopy  (facsimile),  a confirmation  of receipt of the Conversion  Notice
which shall  specify that the  Conversion  Notice has been received and the name
and telephone  number of a contact person at the  Corporation  whom the Series C
Holder should  contact  regarding  information  related to the  conversion.  The
Corporation  shall use all  reasonable  efforts to issue and deliver within five
(5) business  days after the Notice Date, to such Series C Holder at the address
of the Series C Holder on the stock books of the  Corporation,  a certificate or
certificates  for the  number of shares  of Common  Stock to which the  Series C
Holder shall be entitled as  aforesaid;  provided  that the  original  shares of
Series  C  Convertible  Preferred  Stock to be  converted  are  received  by the
transfer  agent or the  Corporation  within  three (3)  business  days after the
receipt of the original  Conversion Notice and the person or persons entitled to
receive  the  shares of Common  Stock  issuable  upon such  conversion  shall be
treated  for all  purposes  as the record  holder or  holders of such  shares of
Common Stock on the Notice Date. If the original certificate(s) representing the
shares of Series C Convertible  Preferred Stock to be converted are not received
by the transfer  agent or the  Corporation  within three (3) business days after
the receipt of the  original  Conversion  Notice,  the  Conversion  Notice shall
become null and void, the Series C Holder shall be so notified, and the Series C
Holder shall be required to initiate a new Conversion  Notice in order to effect
conversion hereunder.

            c. Lost or Stolen  Certificates.  Upon receipt by the Corporation of
evidence  reasonably  satisfactory  to it of the  loss,  destruction,  theft  or
mutilation  of any  Series  C  Convertible  Preferred  Stock  certificates  (the
"Certificates")  and (in the case of loss, theft or destruction) of indemnity or
security  reasonably  satisfactory  to the  Corporation,  and upon surrender and
cancellation of the  Certificates,  if mutilated,  the Corporation shall execute
and deliver new Series C Convertible  Preferred Stock Certificates of like tenor
and date. However,  the Corporation shall not be obligated to re-issue such lost
or stolen  Series C Convertible  Preferred  Stock  Certificates  if the Series C
Holder thereof contemporaneously requests the Corporation to convert such Series
C Convertible  Preferred Stock into Common Stock, in which event the Corporation
shall be entitled to rely on an affidavit of loss,  destruction  or theft of the
Series C Convertible  Preferred Stock  Certificate (and the receipt of indemnity
or  security  reasonably  satisfactory  to the  Corporation)  or, in the case of
mutilation,  tender of the mutilated certificate, and shall issue the Conversion
Shares.

            d. Conversion  Dates.  The shares of Series C Convertible  Preferred
Stock  shall  become  convertible  into  shares  of  Common  Stock  at any  time
commencing  after  the  earlier  of (i) the  effective  date  of a  registration
statement  covering the  Conversion  Shares;  or (ii) ninety (90) days after the
date of filing of the registration statement covering the Conversion Shares. The
date on which a Conversion Notice is transmitted by facsimile to the Corporation
shall be referred to as a "Conversion Date".

            e.  Conversion  Formula/Conversion  Price.  Each  share of  Series C
Convertible  Preferred  Stock shall be convertible  into the number of shares of
Common  Stock  in  accordance  with  the  following   formula  (the  "Conversion
Formula"):

                                     [(.04) x (N/365) x (1,000)] + 1,000
                                               Conversion Price

      where

            N           = the number of days between (i) the Closing Date of the
                        Series C Convertible  Preferred  Stock being  converted,
                        and (ii) the Conversion Date thereof.

            Conversion
            Price       = the  lesser  of (x) 120% of the  five (5) day  average
                        Closing Bid Price of Common Stock  immediately  prior to
                        the Closing Date of the Series C  Convertible  Preferred
                        Stock being  converted or (y) 20% below the five (5) day
                        average  Closing Bid Price of Common  Stock  immediately
                        prior to the Conversion Date thereof.

            Closing
            Date        =  the  date  of  the   Closing  as  set  forth  in  the
                        subscription   agreement  pertaining  to  the  Series  C
                        Convertible Preferred Stock being converted.

                  For purposes  hereof,  the term "Closing Bid Price" shall mean
the closing bid price for a specified date on the Nasdaq  National Stock Market,
or if no longer traded thereon,  the closing bid price on the principal national
securities  exchange on which the Common Stock is so traded, or if not traded on
any such  exchange,  the last bid price on the  principal  market for the Common
Stock.

            f.  Automatic  Conversion.   Each  share  of  Series  C  Convertible
Preferred  Stock  outstanding  on  November  30,  1999  automatically  shall  be
converted  into  Common  Stock on such date in  accordance  with the  Conversion
Formula and the Conversion Price then in effect,  and November 30, 1999 shall be
deemed  to be the  Notice  Date and the  Conversion  Date with  respect  to such
conversion.

            g. Absolute  Limit on  Conversion.  Notwithstanding  anything to the
contrary  contained  in  paragraph  e. of this  Section 6, in no event shall the
Closing  Bid Price of Common  Stock to be used for  purposes  of the  Conversion
Formula set forth in paragraph e. be less than $0.625 per share. Moreover, in no
event shall the Corporation be obligated to issue more than 26,000,000 shares of
its Common Stock in the  aggregate in connection  with the  conversion of any or
all of the Series C Convertible Preferred Stock. Once the Corporation has issued
26,000,000  shares of its Common Stock in the aggregate in  connection  with the
conversion of Series C Convertible  Preferred Stock,  any remaining  outstanding
shares  of  Series  C  Convertible  Preferred  Stock  shall  cease  to have  any
conversion  rights. If at the time the limitation on conversion  provided for in
this paragraph becomes effective,  the Corporation is in receipt of a Conversion
Notice or  Conversion  Notices  pertaining  to  shares  of Series C  Convertible
Preferred Stock which have not been converted and with respect to which complete
conversion  would  exceed such  limitation,  the  Corporation  shall  effect the
conversion of such shares of Series C Convertible  Preferred Stock in accordance
with the  Conversion  Formula  and the  Conversion  Price  then in effect to the
extent the  Corporation  can do so without  exceeding  such  limitation,  in the
chronological  order of its receipt of the Conversion  Notices pertaining to the
conversion of such shares of Series C Convertible  Preferred Stock. In the event
there are insufficient  Conversion Shares to effect the conversion of all of the
shares of Series C Convertible  Preferred  Stock which are the subject of two or
more  Conversion  Notices  received  by the  Corporation  on the same date,  the
remaining  Conversion  Shares  shall be applied  toward the  conversion  of such
shares of Series C  Convertible  Preferred  Stock and  delivered  to the Class C
Holders thereof pro rata in accordance  with their then  respective  holdings of
unconverted  shares of Series C Convertible  Preferred  Stock.  Series C Holders
holding shares of Series C Convertible Preferred Stock which cannot be converted
to Common Stock of the  Corporation  because of the limitation set forth in this
paragraph  shall have the right to require by written notice to the  Corporation
that the Corporation redeem their  unconvertible  shares of Series C Convertible
Preferred Stock in accordance with the terms of Section 5 above. The Corporation
shall  promptly  notify such Series C Holders of the  termination  of conversion
rights  pursuant to this  paragraph  g. and shall issue a  redemption  notice in
accordance with Section 5 above within thirty (30) days after such termination.

            h.  No  Fractional  Shares.  If  any  conversion  of  the  Series  C
Convertible Preferred Stock would create a fractional share of Common Stock or a
right to acquire a fractional share of Common Stock, no fractional  shares shall
be issued and an equivalent of the fractional share shall be paid in cash.

            i.  Reservation of Stock Issuable Upon  Conversion.  The Corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock,  solely for the purpose of effecting  the  conversion of
the shares of the  Series C  Convertible  Preferred  Stock,  such  number of its
shares of Common  Stock as shall from time to time be  sufficient  to effect the
conversion of all then outstanding shares of the Series C Convertible  Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect the  conversion of all then  outstanding
shares of the Series C Convertible  Preferred  Stock,  the Corporation will take
such  corporate  action as may be  necessary  to  increase  its  authorized  but
unissued  shares of Common Stock to such number of shares as shall be sufficient
for such purpose.

            j.    Adjustment to Conversion Price.

                  (i) If,  prior to the  conversion  of all  shares  of Series C
Convertible Preferred Stock, the number of outstanding shares of Common Stock is
increased  by a stock  split,  stock  dividend,  or  other  similar  event,  the
Conversion  Price  shall  be  proportionately  reduced,  or  if  the  number  of
outstanding shares of Common Stock is decreased by a reverse stock split or by a
combination  or   reclassification  of  shares,  or  other  similar  event,  the
Conversion Price shall be proportionately increased.

                  (ii) If,  prior to the  conversion  of all  shares of Series C
Convertible Preferred Stock, there shall be any merger, consolidation,  exchange
of shares, recapitalization, reorganization, or other similar event, as a result
of which  shares of Common  Stock of the  Corporation  shall be changed into the
same or a different  number of shares of the same or another class or classes of
stock or  securities of the  Corporation  or another  entity,  then the Series C
Holders shall  thereafter have the right to purchase and receive upon conversion
of shares of Series C Convertible  Preferred Stock,  upon the basis and upon the
terms and conditions  specified herein and in lieu of the shares of Common Stock
immediately  theretofore  issuable upon conversion,  such shares of stock and/or
securities  as may be issued or payable  with  respect to or in exchange for the
number of  shares  of  Common  Stock  immediately  theretofore  purchasable  and
receivable upon the conversion of shares of Series C Convertible Preferred Stock
held by such  Series C  Holders  had such  merger,  consolidation,  exchange  of
shares, recapitalization or reorganization not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests of
the Series C Holders to the end that the provisions hereof  (including,  without
limitation,  provisions for adjustment of the Conversion Price and of the number
of shares issuable upon conversion of the Series C Convertible  Preferred Stock)
shall  thereafter be applicable,  as nearly as may be practicable in relation to
any  shares of stock or  securities  thereafter  deliverable  upon the  exercise
hereof.  The  Corporation  shall not effect any  transaction  described  in this
subsection  unless  the  resulting  successor  or  acquiring  entity (if not the
Corporation)  assumes by written  instrument  the  obligation  to deliver to the
Series C Holders such shares of stock and/or  securities as, in accordance  with
the foregoing provisions, the Series C Holders may be entitled to purchase.

                  (iii) If any adjustment  under this subsection  would create a
fractional  share of Common  Stock or a right to acquire a  fractional  share of
Common  Stock,  no  fractional  shares  shall be issued upon  conversion  and an
equivalent of the fractional share shall be paid in cash.

      7.    Voting.

            a. Except as otherwise  provided  below or by the  Delaware  General
Corporation Law, the Series C Holders shall have no voting power whatsoever, and
no Series C Holder  shall vote or otherwise  participate  in any  proceeding  in
which actions shall be taken by the Corporation or the  shareholders  thereof or
be entitled to  notification  as to any meeting of the Board of Directors or the
shareholders.

            b. Notwithstanding the above, the Corporation shall provide Series C
Holders with notification of any meeting of the shareholders regarding any major
corporate events  affecting the  Corporation.  In the event of any taking by the
Corporation  of a record of its  shareholders  for the  purpose  of  determining
shareholders  who are  entitled  to  receive  payment of any  dividend  or other
distribution,  any right to subscribe  for,  purchase or  otherwise  acquire any
share of any class or any other  securities  or  property  (including  by way of
merger, consolidation or reorganization),  or to receive any other right, or for
the purpose of determining  shareholders  who are entitled to vote in connection
with any proposed sale, lease or conveyance of all or  substantially  all of the
assets of the Corporation,  or any proposed liquidation,  dissolution or winding
up of the  Corporation,  the  Corporation  shall  mail a notice to the  Series C
Holders,  at least ten (10) days prior to the record date specified therein,  of
the date on which  any  such  record  is to be  taken  for the  purpose  of such
dividend,  distribution,  right or other event, and a brief statement  regarding
the amount and character of such dividend, distribution, right or other event to
the extent known at such time.

            c. To the extent that,  under Delaware law, the vote of the Series C
Holders,  voting  separately as a class, is required to authorize a given action
of the  Corporation,  the affirmative vote or consent of the Series C Holders of
at least a majority of the shares of the Series C  Convertible  Preferred  Stock
represented  at a duly hold  meeting  at which a quorum is present or by written
consent  of the  shares as  required  by  Delaware  law of Series C  Convertible
Preferred  Stock (except as otherwise may be required  under Delaware law) shall
constitute  the  approval of such action by the class.  To the extent that under
Delaware  law the Series C Holders are entitled to vote on a matter with holders
of Common  Stock,  voting  together  as one (1)  class,  each  share of Series C
Convertible  Preferred Stock shall be entitled to a number of votes equal to the
number of shares of Common  Stock  into which it is then  convertible  using the
record date for the taking of such vote of  shareholders as the date as of which
the Conversion Price is calculated.  The Series C Holders also shall be entitled
to notice of all shareholder  meetings or written consents with respect to which
they would be entitled to vote,  which notice would be provided  pursuant to the
Corporation's by-laws and applicable statutes.

      8.    Protective Provisions.

            a. So long as  shares of Series C  Convertible  Preferred  Stock are
outstanding, the Corporation shall not, without first obtaining the approval (by
vote or written consent, as provided by law) of the Series C Holders of at least
seventy-five   percent  (75%)  of  the  then  outstanding  shares  of  Series  C
Convertible Preferred Stock:

                  (i) alter or change the rights,  preferences  or privileges of
the Series C Convertible  Preferred Stock so as to affect adversely the Series C
Convertible Preferred Stock;

                  (ii)  create  any new  class or  series  of stock or issue any
capital stock senior to or having a preference  over or parity with the Series C
Convertible  Preferred  Stock  with  respect to  payments  upon  Liquidation  or
increase the number of authorized shares of Series C Convertible Preferred Stock
or change the Stated Value thereof; or

                  (iii) do any act or thing not authorized or contemplated under
this  Certificate  which would result in taxation of the Series C Holders  under
Section 305 of the Internal  Revenue Code of 1986, as amended (or any comparable
provision of the Internal Revenue Code as hereafter from time to time amended).

      9.    Status of Converted Stock.

            In the event any  shares of  Series C  Convertible  Preferred  Stock
shall be converted as contemplated by this Certificate,  the shares so converted
shall be  canceled,  shall  return to the  status  of  authorized  but  unissued
Preferred Stock of no designated  class or series,  and shall not be issuable by
the Corporation as Series C Convertible Preferred Stock.

      10.   Taxes.

            All  shares of  Common  Stock  issued  upon  conversion  of Series C
Convertible   Preferred   Stock   will  be  validly   issued,   fully  paid  and
nonassessable.  The  Corporation  shall  pay any and all  documentary  stamp  or
similar  issue or transfer  taxes that may be payable in respect of any issue or
delivery  of shares  of  Common  Stock on  conversion  of  Series C  Convertible
Preferred Stock pursuant hereto. The Corporation shall not, however, be required
to pay any tax which may be payable in respect of any  transfer  involved in the
issue and  delivery of shares of Common Stock in a name other than that in which
the Series C Convertible  Preferred Stock so converted were  registered,  and no
such issue or delivery shall be made unless and until the person requesting such
transfer  has  paid  to  the  Corporation  the  amount  of any  such  tax or has
established to the  satisfaction of the Corporation  that such tax has been paid
or that no such tax is payable.

this  Certificate  to be signed by  Michael  J.  Parrella,  its  President,  and

                                         Exhibit A


            RESOLVED,  that the termination or expiration  dates of the warrants
      to purchase common stock of the Corporation  previously granted to certain
      present and former  members of the Board of Directors,  officers and other
      employees of the  Corporation  described in Schedule A attached hereto be,
      and the same hereby are,  extended  for an  additional  two years from the

Dear Sirs

Noise Cancellation Technologies (UK) Limited

We consent to the  incorporation  of our opinion on the financial  statements of
Noise Cancellation Technologies (UK) Limited as of December 31, 1997 and for the
year ended  December 31, 1997,  which report is included in the Annual Report on

Auditors' Report to the Shareholders
on the Financial Statements for the year ended 31 December 1997

We have  audited  the  financial  statements  on pages 4 to 14,  which have been
prepared under the historical  cost  convention and the accounting  policies set
out on page 7.

Respective responsibilities of the directors and auditors

As  described  on  page  1 the  company's  directors  are  responsible  for  the
preparation of the financial  statements.  It is our  responsibility  to form an
independent  opinion,  based on our audit, on those statements and to report our
opinion to you.

Basis of Opinion

We conducted  our audit in  accordance  with  Auditing  Standards  issued by the
Auditing  Practices  Board. An audit includes  examination,  on a test basis, of
evidence relevant to the amounts and disclosures in the financial statements. It
also includes an assessment of the significant  estimates and judgements made by
the directors in the preparation of the financial statements, and of whether the
accounting policies are appropriate to the company's circumstances, consistently
applied and adequately disclosed.

We  planned  and  performed  our  audit  so as to  obtain  all  information  and
explanations  which we consider necessary in order to provide us with sufficient
evidence to give  reasonable  assurance  that the financial  statements are free
from material misstatement, whether caused by fraud other irregularity or error.
In  forming  our  opinion  we  also  evaluated  the  overall   adequacy  of  the
presentation of the information in the financial statements.

Fundamental Uncertainty

In forming our opinion,  we have considered the adequacy of the disclosures made
in note 1 of the  financial  statements  concerning  the  company's  operational
results  and  financial  position.  In view of the  significance  of the company
continuing to generate  adequate working capital,  and its reliance on continued
financial support from the parent company we consider that it should be drawn to
your attention but our opinion is not qualified in this respect.

Opinion

In our opinion the financial  statements  give a true and fair view of the state
of the  company's  affairs as at 31  December  1997 and of its loss for the year
then ended and have been properly  prepared in accordance with the Companies Act
1985.

Going Concern

In forming our opinion,  we have considered the adequacy of the disclosures made

Auditors Report to the Members

We have  audited  the  financial  statements  on pages 6 to 17 which  have  been
prepared under the historical cost convention.

Respective Responsibilities of Directors and Auditors

As described on page 3 the  Company's  directors  are  responsible  for the
preparation of  financial  statements.  It is our  responsibility  to  form  an
independent  opinion,  based on our audit, on those statements and to report our
opinion to you.

Basis of Opinion

We conducted  our audit in  accordance  with  Auditing  Standards  issued by the
Auditing  Practices  Board. An audit includes  examination,  on a test basis, of
evidence relevant to the amounts and disclosures in the financial statements. It
also includes an assessment of the significant  estimates and judgements made by
the directors in the preparation of the fiancial statements,  and of whether the
accounting policies are appropriate to the Company's circumstances, consistently
applied and adequately disclosed.

We  planned  and  performed  our audit so as to obtain all the  information  and
explanations  which  we  considered  necessary  in  order  to  provide  us  with
sufficient evidence to give reasonable  assurance that the financial  statements
are  free  from  material   misstatement,   whether  cause  by  fraud  or  other
irregularity  or error.  In forming  our opinion we also  evaluated  the overall
adequacy of the presentation of information in the financial statements.

Fundamental Uncertainty

In  forming  our  opinion  we  have  considered the adequacy of the  disclosures
made in the  financial  statements  concerning  the  basis of  preparation.  The
financial  statements  have  been  prepared  on a going  concern  basis  and the
validity of this depends on the  Company's  ability to meet its  liabilities  as
they fall due. The  financial  statements  do not include any  adjustments  that
would result from a failure to continue to meet its liabilities.  Details of the
circumstance  relating to this fundamental  uncertainty are described in note 1.
Our opion is not qualified in this respect. Opinion

In our opinion the financial  statements  give a true and fair view of the state
of the Comapny's affairs at 31 December 1995 and of its profit and cashflows for
the year then  ended and have been  properly  prepared  in  accordance  with the
Companies Act 1985.
