                                     PART I

ITEM 1.  BUSINESS

A.       GENERAL DEVELOPMENT OF BUSINESS

         Noise Cancellation Technologies, Inc. ("NCT" or the "Company")
believes it is the industry leader in the design, development, licensing,
production and distribution of electronic systems for Active Wave
Management(TM) including systems that electronically reduce noise and
vibration.  The Company's systems are designed for integration into a wide
range of products serving multi-billion dollar markets in the transportation,
manufacturing, commercial, consumer products and communications industries. 
The Company began commercial application of its technology, with ten products
sold or currently being sold, including the NoiseBuster(TM) consumer headset,
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, an aircraft cabin quieting system
and quieting systems for heating, ventilation and air conditioning ("HVAC")
ducts (NoiseEater(TM)).

         In 1995, the Company introduced industrial headsets and its Adaptive
Speech Filter(TM) ("ASF(TM)"), which the Company believes will have wide
application in the communications and automotive industries.

         In keeping with the direction established in late 1994, during 1995
the Company began the active practice of marketing its technology through
licensing to third parties for fees and subsequent royalties.  In April 1995,
as previously disclosed, the Company licensed its aircraft cabin quieting
technology exclusively to Ultra Electronics, Ltd. ("Ultra") for a license fee
and future royalties.  In November 1995, the Company concluded its previously
disclosed negotiations with Walker Manufacturing Company ("Walker"), a division
of Tenneco Automotive, which resulted in the restructuring of the Walker/NCT
joint venture ("WNCT") and the licensing of certain additional automotive
related technology to Walker for a fee and future royalties.  See G. "Strategic
Alliances" and Note 3. - "Notes to Consolidated Financial Statements.".

         In 1996, the Company plans to introduce additional products for the
communications marketplace, a silicon micro-machined microphone ("SMM"), which
may be used independently or in conjunction with noise reduction, and
additional industrial headset products.  The Company is also refining its
NoiseEater(TM)  product for introduction into international markets.  The 
Company has entered into a joint venture with Applied Acoustic Research, L.L.C.
("AAR") called OnActive Technologies, L.L.C. ("OAT") which is developing Flat
Panel Transducers(TM) ("FPT(TM)") systems utilizing TopDown Surround
Sound(TM)(TDSS(TM)) for automotive applications.  See C. "Technology."





                                       2
<PAGE>   3
         In late 1995 the Company redefined its corporate mission to be the
worldwide leader in the advancement and commercialization of Active Wave
Management(TM) technology.  Active Wave Management(TM) 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(TM), TDSS(TM), FPT(TM), and the SMM, which creates products that the
Company believes will be utilized in areas beyond noise attenuation and
control.  These technologies and products are consistent with the shift of the
Company's  focus to technology licensing fees, royalties and products that
represent 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.

         As distribution channels are established and as product sales and
market acceptance and awareness of the commercial applications of Active Wave
Management(TM) build, 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 reflected in the changed revenue percentages discussed briefly
below and more fully in Item 7. "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

         Active Wave Management(TM) is an evolving industry.  The proportion of
the Company's operating revenues, including technology licensing fees, derived
from engineering and development services, is reflective of this fact. From the
Company's inception through December 31, 1995, approximately 21% of its
operating revenues  have come from the sale of products and 27% of its
operating revenues have come from licensing of the Company's technology, while
approximately 52% 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(TM) is the utilization of active noise
attenuation 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.





                                       3
<PAGE>   4
         NCT believes that it has the leading position in Active Wave
Management(TM) technology, holding more patents and intellectual
property than any other firm in the field. The Company also has an exclusive
license to advanced technology for attenuating noise in a large space, such as
the interior of an aircraft or the passenger compartment of an automobile,
using multiple interactive sensors, such as microphones, and actuators, such as
speakers. Additionally the Company has expanded its portfolio by the
acquisition of various patents, including, in particular the purchase in 1994
of the intellectual property of Active Noise Vibration Technologies, Inc.
("ANVT").

         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. In
exchange for this funding, the other party generally received a preference in
the distribution of cash and/or profits or royalties from these alliances until
such time as the support funding, plus an "interest" factor in some instances,
is recovered.  Due to the restructuring of various alliances, as described in
G. "Strategic Alliances," there were no preferred distributions due to
strategic allies from future profits of the alliances at December 31, 1995. NCT
has established continuing relationships with Walker Manufacturing Company
("Walker") (a division of Tennessee Gas Pipeline Company, a wholly owned
subsidiary of Tenneco, Inc.), AB Electrolux ("Electrolux"), Foster Electric
Company, Ltd. ("Foster"), Analog Devices, Inc. ("ADI"), Ultra Electronics Ltd.
("Ultra"),Harris Corporation ("Harris"), The Charles Stark Draper Laboratory, 
Inc. ("Draper"), Coherent Technologies, Inc. ("Coherent") and 
Applied Acoustic Research, L.L.C. ("AAR"), among others, in order to
penetrate major markets more rapidly and efficiently, while minimizing the
Company's own capital expenditures.  There have been substantial changes to the
terms governing certain of the foregoing relationships as described below and
in Note 3. - "Notes to the Consolidated Financial Statements".

         In February 1995 the Company purchased from Foster Electric, Inc.
("Foster") the exclusive right to manufacture headsets in the Far East.  Due to
the acquisition by the Company in 1994 of the sole ownership of Chaplin Patents
Holding Co., Inc. ("CPH"), neither the Company nor Foster  believed there was
any necessity to continue their supply joint venture, Foster/NCT Supply Ltd.
("FNS"). The Company and Foster dissolved FNS.  The Company and Foster remain
active in the Far East through the Foster/NCT Headsets International ("FNH")
and NCT Far East, Inc. ("NCTFE"), marketing and distribution alliances between
the Company and Foster.  Foster produced six products for NCT in 1995.

         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.  Under the agreement, Ultra
acquired the Company's active aircraft quieting business based in Cambridge,
England, leased a portion of the Company's Cambridge facility and employed
certain of the Company's employees.





                                       4
<PAGE>   5
         On November 15, 1995, the Company and Walker executed a series of
related agreements (the "Restructuring Agreements") and concluded previously
noted negotiations with Tenneco Automotive and Walker 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 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 March 18, 1996, the Company
had 73 employees, including 39 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. Consistent with the Company's revised
strategy to focus on near term product commercialization, technology licensing
fees and royalties during 1995, the Company significantly reduced its work
force and consolidated substantially all of its corporate function in Maryland.

         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, 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

         NCT's goal is to reinforce its position as the world's leader in the
design, development and sale of Active Wave Management(TM) technology and
products.

         The Company revised its strategy and redefined its mission during 1994
and 1995.  The acquisition of certain assets and all of the intellectual
property of ANVT broadened the Company's portfolio of intellectual property and
removed restrictions on the Company regarding licensing of the Chaplin Patents
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.

         In late 1995, as previously noted, the Company redefined its corporate
mission to be the worldwide leader in the advancement and commercialization of
Active Wave Management(TM) technology. Active Wave Management(TM) 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.  The 
redefinition of corporate mission is reflected in the revised business plan 
which the Company  began to implement during the first quarter of  1996.

         In the area of technology licensing fees and royalties, the Company
successfully concluded negotiations with Ultra in the first quarter of 1995,
which amended the teaming agreement and instituted a licensing and royalty
agreement.  In November of 1995, the Company concluded similar negotiations
with Walker.  During the course of 1995, the Company successfully concluded
certain other licensing agreements. The Company is pursuing other negotiations
and plans to expand this sector of the business during 1996.
        
         NCT produces and sells MRI headsets and industrial headsets through
various distributors, and also licenses, produces and sells ASF(TM).  The
Company is offering its NoiseBuster(TM) headset to consumer markets at a
suggested retail price of $79, and is selling the NoiseBuster(TM) through
various distribution channels, including specialty electronics retail stores,
specialty catalogs and direct sales by advertising a dedicated "800" telephone
number.

         In 1996, the Company plans to introduce additional headset products,
the silicon micro-machined microphone, and additional communications systems
products that improve the intelligibility and quality of voice and data 
transmission and recognition.

         At the core of the Company's strategy is its leadership in Active Wave
Management(TM) technology.  NCT secured its basic technology by acquiring its
interest in the Chaplin Patents and the exclusive ownership of 10 patents known
as the "NRDC Patents" described below under Item D. "NCT Proprietary Rights and
Protection".   The Company further solidified its position regarding the
Chaplin Patents through the 1994 acquisition of the intellectual property of
ANVT, which also brought a number of other patents to NCT.   In addition, the
Company has developed or acquired a number of patents, licenses and proprietary
inventions that improve and enhance the features and capabilities of its basic
technology.  NCT's basic and enhanced technologies have enabled the Company to
develop and patent specific product applications in Active Wave Management(TM),
as well as enter new markets such as telecommunications and audio.





                                       6
<PAGE>   7
         The Company has implemented its business strategy in the past by
forming strategic supply, manufacturing and marketing alliances with leading
global companies in an effort to commercialize its technology.  The strategic
alliances established by NCT have historically funded a majority of the
Company's research and development and currently provide reliable sources of
components, manufacturing expertise and capacity, as well as extensive
marketing and distribution capabilities. The Company continues this practice.
However, the acquisition of the intellectual property of ANVT, as previously
noted, allows the Company more flexibility in the type of alliances and license
agreements it concludes.

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
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

                                   [CHART]


         Active Wave Management(TM). Active Wave Management(TM) 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(TM) 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 or for
data transmissions to be communicated with fewer errors.  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.

         EarPeace(TM).  NCT has been working to integrate its proprietary
active noise control technology into in-flight entertainment systems and
telephone handsets in particularly loud environments.  To facilitate the
penetration of this cost-sensitive marketplace, NCT has developed a proprietary
acoustical design approach that minimizes the electronics costs needed to
effectively cancel noise. EarPeace(TM) technology is available today to meet
the low cost and small size requirements of previously inaccessible markets.
NCT is currently working with manufacturers of passenger control units (PCU), 
airphones, pay telephones and industrial handsets to reduce the ambient 
background noise and improve audio or communications intelligibility.

         Silicon Micromachined Microphone (SMM).  In 1994, NCT purchased the
exclusive rights to manufacture and commercialize a silicon micromachined
microphone.  A small, compact, surface-mountable silicon actuator, the SMM
provides customers





                                       8
<PAGE>   9
improved and adjustable sensitivity, a low noise floor and resistance
to environmental extremes.  The ability to integrate additional circuitry onto
the SMM chip has also proven attractive to potential users. The SMM's low noise
floor and adjustable sensitivity improves voice recognition in high ambient
noise environments.  NCT is working with voice processing computer hardware
companies to utilize the SMM to enhance the performance of their systems.  In
addition, NCT is currently in negotiation with hearing aid manufacturers to 
provide the SMM as a replacement for the more expensive electret microphones 
currently employed in hearing aids.

         Adaptive Speech Filter(TM) ("ASF(TM)").  The Adaptive Speech 
Filter(TM) algorithm (ASF(TM)) removes background noise from voice and data 
transmission and recognition.  Available in real-time single and double 
precision fixed-point digital signal processing ("DSP"), floating-point DSP, 
and Windows 95/Windows NT ACM driver versions, ASF(TM) can be used as a 
pre-processor for voice and data compression algorithms, and also contributes 
to improved voice and data recognition.  ASF(TM) 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.  Additional uses include 
teleconferencing systems, cellular and airphones, telephone switches, echo 
cancellers, and communications systems in which background noise is 
predominant.  ASF(TM) is currently available for use on three hardware 
platforms.  The Company is in the process of adding an echo cancellation 
algorithm to ASF(TM).  This addition should be completed in 1996.

         NCT Audio.  Consistent with its expertise in Active Wave Management(TM)
and its experience in accurately reproducing acoustical patterns for the
purpose of noise attenuation, the Company has expanded its audio transducer
work to include audio systems for the reproduction of speech and music. The
Company is developing Top Down Surround Sound(TM) ("TDSS(TM)") for the
automobile audio market, in both original equipment manufacturer ("OEM") and
after-market versions.  TDSS(TM) employs Flat Panel Transducers(TM) ("FPT(TM)")
to produce sound much closer to the listener's ear than conventional speakers.
This placement allows for a High Impact Sound(TM) listening experience.  The
Company is also developing FPT(TM) for personal computers and
telecommunications.  In these applications, the slim profile of the FPT(TM)
allows for placement where conventional speakers cannot be accommodated.

D.       NCT PROPRIETARY RIGHTS AND PROTECTION

         NCT believes it has the leading position in Active Wave
Management(TM), holding a large number of patents and patent applications.
The Company's strategy has been to build upon its base of core technology
patents with newer advanced technology patents developed 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.





                                       9
<PAGE>   10
         During 1994 the Company purchased certain assets of ANVT, which
included all of ANVT's intellectual property rights. See Note 14. - "Notes to
the Consolidated Financial Statements".  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.

         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.





                                       10
<PAGE>   11
         In 1994, the Company purchased the exclusive rights to the silicon
micromachined microphone technology developed by Draper in
Cambridge, Massachusetts.  At that time, two patents describing the basic
technology had already been issued and two were pending.  On September 19,
1995, one of the patents pending was issued.

         In 1995 the Company also acquired several U.S. patents dealing with
adaptive speech filtering which it hopes to license to third parties.

         The Company holds or has rights to 202 inventions as of December 31,
1995, including 69 United States patents and over 177 corresponding foreign
patents.  The Company has pending over 190 US and foreign patent applications..
NCT's engineers have made 60 invention disclosures for which the Company is in
the process of preparing patent applications.

         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'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

         HEADSETS

         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(TM). NCT is currently marketing its NoiseBuster(TM)
personal active noise reduction headphone for consumers at a suggested retail
price of $79.  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(TM) is a
lightweight, portable headphone wired to a small controller that can be clipped
to the user's clothing or belt.  The NoiseBuster(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.

         NoiseBuster(TM) is the largest selling consumer product of its kind.
NoiseBuster(TM) was awarded the 1994 Discover Magazine Technological Innovation
Award and the Electronics Industry Association's Innovation 95 Award.

         The Company is marketing the NoiseBuster(TM) through distribution
channels, including electronics retail stores, specialty catalogues and 
directly through a toll-free "800" number.  Initial product shipments
were made in September 1993.

         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(TM).  At 6.9 oz, one-third the weight of other active noise
reduction headsets, the Airman ANR(TM) 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.

<PAGE>   13
         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, openback 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 shipped a hard
hat version of its ProActive(TM) 3000 line.  This will be 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 shipment
is scheduled for mid 1996.

         COMMUNICATIONS

         Adaptive Speech Filter ("ASF(TM)"). ASF(TM) removes background noise
from voice and data transmission and recognition.  Available in real-time
single and double precision fixed-point DSP, floating-point DSP, and Windows
95/Windows NT ACM driver versions, ASF(TM) 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.

         DUCT QUIETING SYSTEM-NOISEEATER(TM)

         The Company has developed low-cost quieting systems for installation
into existing HVAC ducts.  The Company is selling kits of its duct quieting
systems for integration into the most common duct sizes and the Company
believes these systems will be easy to install by HVAC workers in office
buildings and factories.  The Company began offering this product line
commercially as the NoiseEater(TM) in January 1994 selling through
distributors, and is currently offering these systems for sale in the United
States.  In 1995, the Company successfully concluded license and royalty
agreements with distributors in Europe and Japan.

F.       PRODUCTS UNDER DEVELOPMENT

         HEADSETS

         NB-PCU.  The Company is working with a leading manufacturer and
supplier of aircraft cabin products on the integration of NCT's Ear Peace (TM)
active noise control technology into in-flight passenger entertainment systems.
As a component of the system, NCT is also developing 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.
Production systems should be available in the latter part of 1996.

         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.

         COMMUNICATIONS

         Active Noise Reduction for Telephone Handsets.  NCT is currently
working to integrate its proprietary active noise control technology,
EarPeace(TM), into telephone handsets. The EarPeace(TM) is scheduled for
production in 1996.  The most appropriate application for handsets
incorporating this technology is in environments where the loud ambient
background noise impedes communications intelligibility and interferes with the
comfort of the user.  Examples of such environments include aircraft cabins,
noisy factory floors, large telemarketing environments and phones located on
street corners and highways.

         Silicon Micromachined Microphone ("SMM").  In 1994, NCT purchased 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 1995, the Company signed a memorandum of understanding with
a major semiconductor manufacturer to build the SMM.  In the first quarter of
1996, the manufacturer released initial prototypes of the devices.  This
manufacturer is currently refining the manufacturing process and identifying a
facility for production.  Production of two general purpose SMMs is expected to
commence in the first quarter of 1997.

         NCT AUDIO

         Top Down Surround Sound(TM), TDSS(TM) 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 High Impact Sound(TM)
which TDSS(TM) generates.  The Company is in the process of developing teaming
agreements with major participants in the automobile audio speaker market and
is also exploring applications for High Impact Sound(TM) technology in the home
audio and home theater environments.

         Flat Panel Transducers(TM),  Using a similar FPT(TM) technology to that
employed in TDSS(TM), multi-media FPT(TM) targets such applications as notebook
computers and video telephones.  In these applications the slim profile of the
FPT(TM) offers an audio transducer solution where room may be lacking to
implement a conventional speaker.

         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





                                       15
<PAGE>   16
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 can 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.  The Company expects to begin shipping kitchen
hood systems in the last half of 1996.

         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 strategy is to obtain technology licensing fees and
royalties, and, in certain areas, to produce, market and sell Active Wave
Management(TM) products.

         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(TM)  systems is predicated upon the establishment 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 provide marketing, distribution and
manufacturing capabilities for the Company's products and enable the Company to
limit the expense of its own research and





                                       16
<PAGE>   17
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:

         WALKER MANUFACTURING COMPANY (A DIVISION OF TENNESSEE GAS PIPELINE
         COMPANY) (U.S.)  WALKER ELECTRONIC MUFFLERS, INC. (A WHOLLY OWNED
         SUBSIDIARY OF TENNESSEE GAS PIPELINE COMPANY) (U.S.)

         In November 1989, NCT signed its strategic alliance with Walker, a
world-leading manufacturer of automotive parts and mufflers.  The alliance
consisted of a Joint Venture and Partnership Agreement with ownership in the
resulting joint venture WNCT shared equally between NCT Muffler, Inc. and
Walker Electronic Mufflers, Inc. ("WEM"), a wholly owned subsidiary of
Tennessee Gas Pipeline Company). WNCT conducts research and develops,
manufactures, markets, sells and distributes electronic mufflers principally
for use on non-military, land-based vehicles on an exclusive basis, and for the
industrial (e.g., compressors, diesel generators and gas turbines), marine,
consumer and aerospace sectors on a non-exclusive basis.  The agreement between
NCT and Walker was expanded and extended in 1991. WNCT is currently producing
and selling industrial silencers.





                                       17
<PAGE>   18
         In December 1993, Tenneco Automotive, another division of Tennessee
Gas Pipeline Company, and the Company entered into an agreement pursuant to
which Tenneco Automotive purchased 1,110,083 shares of the Company's common
stock for $3.0 million in cash.  Pursuant to the agreement,  the Company
contributed $1.0 million to the capital of the WNCT following which WNCT repaid
$1.0 million of the capital advances previously made to WNCT by WEM and
representatives of WEM and the Company agreed to restructure WNCT.  Such
restructuring included giving WNCT worldwide rights for the manufacture and
sale of all muffler products except those manufactured and sold in the consumer
and defense markets. WNCT also was expanded to have, in addition to rights it
has with respect to vehicular mufflers, worldwide non exclusive rights to all
silencing and vibration applications (e.g., mufflers, cabin quieting, engine
mounts, fan quieting and engine block quieting) for all vehicles except trains,
aircraft and watercraft.  The Company committed to help fund $4.0 million of
product and technology development work of the Company attributable to WNCT.
Also pursuant to the agreement with Tenneco Automotive, Walker's right to
acquire the Company's interest in WNCT upon the occurrence of certain events
was eliminated and Tenneco Automotive had the right to have a representative
serve on the Company's Board of Directors.

         On November 15, 1995, the Company and Walker executed a series of
related agreements (the "Restructuring Agreements") and concluded previously
noted negotiations with Tenneco Automotive and Walker 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 to Walker, the elimination of the Company's previously expensed obligation
to fund the remaining $2.4 million of product and technology development work
noted above, 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 (see 
Note 3. - Notes to the Consolidated Financial Statements).

         AB ELECTROLUX (SWEDEN)

         The Company's relationship with Electrolux, one of the world's leading
producers of white goods, was initiated in October 1990.  The Company signed
its current agreement with Electrolux, a Joint Development and Supply
Agreement, in June 1991.  This agreement provides for NCT to design, develop
and supply active systems for quieting Electrolux products.  Electrolux has
agreed to purchase the electronic components for its active noise control
products exclusively from NCT, provided the Company and its supply joint
ventures are price and quality competitive.  To date, NCT has completed
development of two household appliance products for Electrolux.  No date has
been established for product introduction.

         FOSTER ELECTRIC COMPANY, LTD. (JAPAN)

         In March 1991, NCT and Foster, the largest original equipment
manufacturer of speakers in the world and a major producer of stereo headsets
and high-fidelity components for the consumer electronics and automotive
industries, established a joint venture, FNH, to develop, design, manufacture
and sell active noise attenuation headset systems. Foster is responsible for
production of the NoiseBuster(TM) consumer headset, the aviation headset and
the industrial headsets.  Ownership was shared equally between Foster and NCT.

         In addition to their headset joint venture, in April 1991, NCT and
Foster entered into a supply joint venture, FNS, (owned 30% by NCT) to build
and supply the customized components NCT requires to build its active systems,
including sensors, microphones, amplifiers, transducers and controllers.  These
components were sold by  FNS to NCT which distributes them to other NCT
production and distribution ventures and customers.

         In December 1993, Foster and the Company entered into an agreement
pursuant to which Foster purchased 740,055 shares of the Company's common stock
for $2.0 million (the "Foster Shares").  Under the terms of the agreement,
Foster paid the purchase price by means of a cash payment of one cent ($.01)
per share (the par value of the common stock) and the delivery of a series of
promissory notes (the "Foster Notes") in aggregate principal amount equal to
the balance of the purchase price.  The Foster Notes were full recourse notes
of Foster bearing interest at one percent above the rate of three-year United
States Treasury Notes and were to mature on April 17, 1997.  The Foster Notes
were collateralized by the Foster Shares until paid or "earned out" as
described in the next paragraph.  As of December 31, 1995, the Foster Notes
had been paid in full.

         Foster and the Company also agreed that Foster would provide and the
Company would purchase $2.0 million of various product and market development
services deemed necessary by the Company for the commercialization of several
new headset and other products and the further development of the Company's
Japanese markets during the period from December 1993 to April 1997.  The
Company would define each project or phase of this work and Foster would
provide related budgets and performance milestones.  Upon completion of each
such project or phase, the agreed budgeted amount therefor would be billed to
the Company and will be paid, at the Company's election, either in cash or by
discharge of an equivalent amount of the Foster Notes, in which latter event an
appropriate number of the Foster Shares would be released from the
collateralization restrictions.

<PAGE>   20
         In February 1995, the Company and Foster agreed to liquidate FNS.
Foster and the Company have agreed that the acquisition of certain assets of
ANVT by NCT (see Note 14, - Notes to the Consolidated Financial Statements)
removed the necessity for the continued existence of FNS.  An orderly
liquidation of FNS was completed in April 1995.  The agreement provided for the
Company's repurchase from Foster for $0.6 million of the exclusive headset
manufacturing rights in the Far East (see FNH note above) and an immediate
minimum 5% reduction in the price of headset products to be produced by Foster
for the Company.  The Company accrued a $0.8 million charge in 1994 relating to
this agreement, of which $0.2 million was reflected as a current liability at
December 31, 1994.

         On July 28, 1995, Foster Electric Co., Ltd. ("Foster"), Foster NCT
Headsets International ("FNH") and the Company executed a letter agreement
amending the 1991 agreement covering the headset joint venture company, FNH.
Pursuant to that agreement Foster acquired the Company's 50% interest in FNH
and a license to manufacture headsets for FNH and NCT with tooling currently
owned by NCT in consideration for Foster's assumption of FNH's outstanding
liabilities of $303,000. The agreement also grants FNH the right to sell
certain headsets on an exclusive basis in Japan and a non-exclusive basis
throughout the rest of the Far East, in consideration for a royalty on the sale
of such headsets.

         The Company and Foster remain active in the Far East through NCTFE, a
sales and marketing joint venture between the Company and Foster.   Foster
produced six products for NCT in 1995, primarily industrial headsets

         The Company's Far East marketing and product showroom facility is
maintained at Foster's facilities in Tokyo, Japan.

         ULTRA ELECTRONICS LTD. (U.K.)

         Since 1991, NCT and Ultra and its predecessor, part of the Dowty
Group, have been designing and developing systems to enhance passenger comfort
by quieting aircraft passenger compartments in certain propeller driven
aircraft, which Ultra sells to the worldwide turbo-prop aircraft market.  In
May 1993, Ultra and the Company signed a teaming agreement to produce and
install the NCT cabin quieting system on the SAAB 340 aircraft.  Deliveries
under this agreement began in 1994.  In March 1995, the Company and Ultra
amended the teaming agreement and concluded a licensing and royalty agreement
for $2.6 million.  In addition, Ultra will pay the Company a royalty of 1 1/2%
of  sales of products incorporating NCT technology  beginning in 1998.

         ANALOG DEVICES, INC. (U.S.)

         In June 1992, NCT and ADI formed an equally owned joint venture to
design, develop, and manufacture computer chips to be incorporated in the
Company's active noise and vibration control systems.  ADI is a leading
manufacturer of precision, high-performance integrated circuits used in analog
and digital signal processing applications.  Under the terms of the agreement,
ADI, as a subcontractor to the joint venture, will complete the design and
development of specialized chips incorporating NCT's technology.

]         HARRIS CORPORATION (U.S.)

         In September 1993, the Company and Harris entered into an agreement to
form an equally owned limited liability company to design, develop and
manufacture custom electronic components incorporating NCT patents and
technology for use in the Company's active noise and vibration control systems
and to sell such components to NCT and NCT's customers.  Harris is a worldwide
designer and supplier of advanced electronic systems, semi-custom and custom
integrated circuits and semiconductors, communications systems and equipment
and electronic office products.  Under the terms of the agreement, Harris, as a
subcontractor to the limited liability company, is working with the Company in
the design and development of custom and semi-custom electronic components and
will manufacture the specialized components incorporating the Company's
technology.

         THE CHARLES STARK DRAPER LABORATORY, INC. (U.S.)

         In July 1994, NCT and Draper Laboratory ("Draper") of Cambridge, 
Massachusetts entered into an agreement whereby NCT became the exclusive 
licensee to a new silicon micromachined microphone developed by Draper.  Under 
terms of the agreement and subsequent agreements, Draper will perform 
engineering services for NCT to further develop the technology.  The 
microphone technology has application in a wide variety of applications within 
the acoustic and communications fields.

         COHERENT COMMUNICATIONS SYSTEMS CORPORATION (U.S.)

         In June 1995, NCT and Coherent of Leesburg, Virginia  entered into an 
agreement whereby NCT granted a license to Coherent to sell and Coherent and 
NCT will work together to develop and sell certain telecommunication products.

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 FPT(TM) and TDSS(TM), into total audio systems and
solutions for the automotive OEM market. Both partners, who own equal shares of
the joint venture, have licensed their proprietary technology to the joint
venture.

H.       MARKETING AND SALES

         In addition to marketing its Active Wave Management(TM) technology and
systems through its strategic alliances as described above, the Company also
uses an internal sales force of eight people, its executive officers and
directors, and four  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.  The Company intends to continue to expand its internal sales force
on a limited basis as resources become available.

         Revenues derived from the Company's contractual relationships with
Walker and Ultra (see Note 3. - "Notes to the Consolidated Financial
Statements") accounted for 38.2% and 30.1% respectively, of the Company's
revenues for the year ended December 31, 1995.  No other customer accounted for
more than 10% of revenues during such fiscal period.

         The Company's backlog at December 31, 1995, was $950,000 as contrasted
with $1,647,000 at December 31, 1994, and $1,450,000 at December 31, 1993,
respectively.  In 1995 and 1994, the backlog was composed primarily of future
product shipments.  In 1993 the backlog was composed primarily of engineering
and development service contracts.  Since the Company's strategy is to focus on
technology  licensing  fees, royalties, product revenue and the introduction of
products which management believes have near term commercial potential, backlog
of engineering and development services is not a relevant measure for the
Company at this stage of its commercial development.

         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, 1995 and 1994.

         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.       COMPETITION

         The Company is aware of a number of direct competitors in the field of
active noise and vibration attenuation.  Indirect competition also exists in
the field of passive sound and vibration attenuation.  The Company's principal
known competitors in active control systems are Andrea Electronics Corporation,
Bose Corporation, Digisonix (a division of Nelson Industries, Inc.), Hitachi,
Ltd., Group Lotus PLC and Lotus Cars Limited, Lord Corporation, Matsushita
Electric Industrial Co., Ltd., Sennheiser Electronic Corp., Sony Corporation
and Toshiba Corporation, among others.  To the Company's knowledge, each of
such entities is pursuing its own technology in active





                                       22
<PAGE>   23
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 automobile and appliance manufacturers, and aircraft parts suppliers
and manufacturers, have research and development efforts underway in 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 as the industry develops, are well established and have substantially
greater management, technical, financial, marketing and product development
resources than the Company.

J.       GOVERNMENT CONTRACTS

         The Company has acted as a government subcontractor in connection with
its performance of certain engineering and development services.  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.

K.       RESEARCH AND DEVELOPMENT

         Company-sponsored research and development expenses aggregated $4.8
million, $9.5 million and $8.0 million for the fiscal years ended 
December 31, 1995, 1994 and 1993, respectively.

         In addition, the Company's co-venturers and customers have funded
engineering and development expenditures to determine the feasibility of
applying the Company's technology to their requirements and to develop
functional prototypes for their potential applications.  These expenditures are
estimated at $2.3 million, $4.2 million and $2.8 million for the fiscal years
ended December 31, 1995, 1994, and 1993, respectively.

L.       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.

M.       EMPLOYEES

         The Company had 73 employees on March 18, 1996.  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's maintains a sales and marketing office in Stamford,
Connecticut where it leases approximately 2500 square feet of space under a
lease which expires in December 2001 and provides for a current monthly rental 
of approximately $2,500.

         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 the
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 Lira ($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 Lira ($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
hearing before the Tribunal of Milan is scheduled for May 30, 1996.  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 judgement against the Company, said
judgement could have a severe material effect on quarterly or annual operating
results.

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


         GENERAL BUSINESS ENVIRONMENT

         The Company is in transition 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. In prior years, 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 1995, the Company received
approximately 22% of its operating revenues from engineering and development
funding, compared with 61% in 1994.  Since 1991, revenues from product sales
have been increasing and 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 is now 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(TM) from participating in certain commercial
areas without licenses from the Company.

         Notes 1. and 15. 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 and the uncertainties
which exist that raise substantial doubt as to the Company's ability to
continue as a going concern.

         At a Board of Directors Meeting on July 6, 1995, the following
executive changes were implemented:  The Company's former Executive
Vice-President was appointed President and the then Co-Chairman of the Board,
Chief Executive Officer and President retained the positions of Co-Chairman of
the Board and Chief Executive Officer.

         As previously disclosed, the Company has implemented changes in its
organization and focus, beginning 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(TM) technology.  
Active Wave Management(TM) 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(TM),
TDSS(TM), FPT(TM), and the SMM, which create products that the Company believes
will be utilized in areas beyond noise and vibration reduction and control.
These technologies and products are consistent with shifting the Company's 
focus to technology licensing fees, royalties and products that represent near
term revenue generation.  The redefinition of corporate mission is reflected in
the revised business plan which the Company began to implement in the first
quarter of 1996.





                                       28
<PAGE>   29
         As distribution channels are established and as product sales and
market acceptance and awareness of the commercial applications of Active Wave
Management(TM) build, 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 December 1994, the Company adopted a plan that management believed
would generate sufficient funds for the Company to continue its operations into
1996.  During 1995, the Company generated $6.6 million in license fees and $1.6
million in product sales. While the Company has exceeded its expectations
through December 1995 regarding technology licensing fees, production delays
and market acceptance have slowed new product sales. Operating expenses have
been reduced throughout 1995 and were less than projected in the plan adopted
in December 1994. Success in generating technology licensing fees, royalties
and product sales are significant and critical to the Company's ability to
overcome its present financial difficulties. 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, 1995, its operating
revenues, including technology licensing fees and royalties, product sales and
engineering and development services, have consisted of approximately 21%
product sales, 52% engineering and development services and 27% 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 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. 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.





                                       29
<PAGE>   30
         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.
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 58% from 173 to 73 current employees as of
March 18, 1996.

         Because the Company will not meet its revenue targets for the first
quarter of 1996, it has entered into two recent transactions, which provide
additional funding as follows:

         On March 28, 1996, the Company sold 2,000,000 shares of its common
stock in a private placement that provided net proceeds to the Company of $0.7
million.

         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 $0.35
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 
$35 per share subject to certain adjustments.  The conversion of the notes
and the exercise of the options are both subject to stockholder approval of an
appropriate amendment to the Company's Certificate of Incorporation increasing
its authorized capital to provide for the requisite shares.  In conjunction
with the foregoing sale of common stock and convertible term notes, the Company
also agreed to file a registration statement with the Securities and Exchange
Commission ("SEC") covering the applicable shares and to use its best efforts
to have such registration statement declared effective by the SEC as soon as
practicable.  The relevant agreements provide for significant monetary
penalties in the event such registration statement is not declared effective
within 90 days of the filing date and in the event its effectiveness is
suspended for other than brief permissible periods.  The agreements also
prohibit the Company from concluding any further financing arrangements which
involve the sale of equity or an equity feature without the investors' consent
for a period of one year.





                                       30
<PAGE>   31
         The total cash received to date by the Company  from the above two
transactions amounts to $2.2 million.  (Refer to Notes 1. and 15. - "Notes to 
the Consolidated Financial Statements.")

         Management believes that the funding provided by increased product
sales, technology licensing fees, royalties, and cost savings, if realized,
coupled with the additional capital referred to above, some of which is
dependent upon shareholder approval of an amendment to the Company's
Certificate of Incorporation, should enable the Company to continue operations
into 1997.  If the Company is not able to increase technology licensing fees,
royalties and product sales, or generate additional capital, it will have to
further cut its level of operations substantially in order to conserve cash.
(Refer to "Liquidity and Capital Resources" below and to Note 1. - "Notes to the
Consolidated Financial Statements" for a further discussion relating to
continuity of operations.)

         RESULTS OF OPERATIONS

Year ended December 31, 1995 compared with year ended December 31, 1994.

         Total revenues in 1995 increased by 47% to $10,466,000 from $7,124,000
in 1994.  Total expenses during the same period decreased by 50% or
$14,497,000, reflecting the continuing results of cost reduction plans.

         Technology licensing fees increased by 1,356% or $6,128,000 to
$6,580,000, reflecting the Company's continuing emphasis on expanding
technology licensing fee revenue. The 1995 amount is principally derived from a
$2.6 million license fee from Ultra, a $ 3.3 million license fee from Walker
and other licenses aggregating $0.7 million.  In 1994, technology license fees
amounted to $0.5 million.  See Note 3. - "Notes to the Consolidated Financial
Statements".

         Product sales decreased by 32% to $1,589,000 reflecting a reduction in
orders for MRI headsets from Siemens, decreased revenue from NoiseBuster(TM)
sales due to reductions in average price and units sold, and a decrease in
industrial silencer sales in connection with the transfer of that business to
Walker.

         Engineering and development services decreased by 47% to $ 2,297,000,
primarily due to 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 decreased 61% to $1,579,000 from $4,073,000 and
the product margin increased to 1% from (74%) in 1994.  The negative margin in
1994 was primarily due to a reserve for slow moving and  obsolete inventory in
the amount of $1,855,300.  In 1995, the low product margin was primarily due to
the lower sales price of the NoiseBuster(TM).





                                       31
<PAGE>   32
         Cost of engineering and development services decreased 44% to
$2,340,000 primarily due to the changes in the Ultra and Walker relationships,
as noted above.

         Selling, general and administrative expenses for the year decreased by
42% to $5,416,000 from $9,281,000 for 1994. Of this decrease, $1,202,000 was
directly attributable to salaries and related expenses. Advertising and
marketing expenses decreased by 65% to $677,000. Office and occupancy expenses
decreased by 73% or $537,000. Professional fees increased by 55% to $1,933,000
primarily due to legal fees related to litigation and patent prosecution and
maintenance. Travel and entertainment decreased by 58% or $533,000.

         Depreciation and amortization included in selling, general and
administrative expenses decreased by $22,000 or 10%, from $221,000 to $199,000.

         Research and development expenditures for 1995 decreased by 50% to
$4,776,000 from $9,522,000  for 1994, primarily due to realizations from the
cost savings plans and staff reductions.

         In 1995, interest income decreased to $53,000 from $587,000 in 1994
reflecting the decrease in 1995 of available funds to invest.

         Under all of the Company's existing joint venture agreements at the
end of 1995, the Company is 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 agreement with Tenneco
Automotive entered into in December 1993 resulted in the recognition of 1994
losses with respect to the joint venture with Walker in the amount of
$1,453,200.  The aggregate amount of the Company's share of losses in all of
its joint ventures in excess of the Company's investments which has not been
recorded was approximately $0.9 million at December 31, 1994.  Due to the
Company's sale and transfer of its interest in various of its joint ventures in
1995, there was no such unrecorded losses as of December 31, 1995.

         The Company has net operating loss carryforwards of $58.7 million and
research and development credit carryforwards of $1.2 million for federal
income tax purposes at December 31, 1995.  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.





                                       32
<PAGE>   33
Year ended December 31, 1994 compared with year ended December 31, 1993.

         Total revenues for 1994 increased by 32% to $7,124,000  from
$5,385,900 in 1993.

         Product sales advanced 35% to $2,337,000 reflecting sales of the
NoiseBuster(TM) consumer headset into several distribution channels, shipments
of MRI headsets to Siemens and industrial headsets to Telex.  Engineering and
development services increased by 20% to $4,336,000 primarily due to the
additional project funding from Ultra for aircraft cabin quieting and from WNCT
for vehicle mufflers.

         Licensing fees in 1994 were comprised of a  $141,000 net license fee
from Mitsuya for limited NoiseEater(TM) rights in Japan, a $250,000 license fee
from QSI, a related party, (see Item 13. "Certain Relationships and Related
Transactions" and  Note 3. - "Notes to the Consolidated Financial Statements") 
for rights in the electric utility transformer retro-fit market, and a $60,000 
fee from Unikeller Group, Switzerland. During 1993, the only license fee 
recorded was a $60,000 fee from a development agreement with Unikeller Group
for sound attenuation in passenger vehicle cabins.

         Cost of product sales increased 211% to $4,073,123 and the product
margin decreased to (74%) from 24% in 1993, primarily due to a reserve for slow
moving and  obsolete inventory in the amount of $2,032,000.  Cost of
engineering and development services increased 50% to $4,192,000 due to
increased contracts, primarily Ultra.

         Selling, general and administrative expenses for the year increased by
28% to $9,281,117 from $7,231,000 for 1992.  Of this increase $600,000 was due
to the  purchase of the manufacturing rights in the Far East from Foster (see
Note 3. - "Notes to the Consolidated Financial Statements").  In 1994, the
Company recorded $375,000 of realized and unrealized losses in its investments,
versus a $258,000 realized gain in its investments in 1993.

         Advertising and marketing expenses increased by $671,000 or 52%,  from
$1,286,000 to $1,957,000, primarily due to increased expenditures to open
distribution channels for the NoiseBuster(TM), and office and occupancy
expenses increased by $105,000 or 17%, from $626,000 to $731,000,  primarily to
support the advertising and marketing efforts above.

         Depreciation and amortization included in selling, general and
administrative expenses increased by $67,000 or 44%, from $154,000 to $221,000,
reflecting the increased amortization of intellectual property acquired from
ANVT (see Note 14. - "Notes to the Consolidated Financial Statements").

         Research and development expenditures for 1994 increased by 20% to
$9,522,000 from $7,962,900 for 1993.





                                       33
<PAGE>   34
         In 1994, interest income increased to $587,510 from $313,200 for 1993.
This increase was due primarily to the income from the investment of the
unexpended proceeds from the 1993 public offering of common stock, which were
invested, along with the Company's other available cash, in U.S. Treasury bills
and high quality bond funds. The Company's net yield on its investments during
1994 averaged 5.7%.

         Under most of the Company's joint venture agreements, the Company is
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 agreement with Tenneco Automotive entered
into in December 1993 resulted in the recognition of 1994 losses with respect
to the joint venture with Walker in the amount of $1,453,200.  The aggregate
amount of the Company's share of losses in all of its joint ventures in excess
of the Company's investments which has not been recorded was approximately $0.9
million at December 31, 1994.  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.

         The Company had net operating loss carryforwards of $58.7 million and
research and development credit carryforwards of $1.2 million for federal
income tax purposes at December 31, 1994.  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.

         LIQUIDITY AND CAPITAL RESOURCES

         The Company received $0.7 million from the exercise of stock purchase
warrants and options during 1995, $1.0 million in 1994 and $2.1 million in
1993.

         On August 4, 1995, the Company sold 2,000,000 shares of its common
stock in a private placement that resulted in $0.7 million net proceeds to the
Company. Additionally, on November 14, 1995, the Company sold 4,800,000 shares
of its common stock in a private placement that resulted in $3.3 million net
proceeds to the Company.

         In March 1995, the Company and Ultra amended the teaming agreement
and concluded a licensing and royalty agreement for $2.6 million.  In addition,
Ultra will pay the Company a royalty of 1 1/2% of sales of products
incorporating NCT technology beginning in 1998.

         On November 15, 1995, the Company and Walker executed a series of
related agreements which provided for the transfer of the Company's interest 
in WNCT to Walker, the elimination of the





                                       34
<PAGE>   35
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.

         The Company has incurred substantial losses from operations since its
inception, which have been recurring and amounted to $72.8 million on a
cumulative basis through December 31, 1995.  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 December 1994, the Company adopted a plan that management believed
would generate sufficient funds for the Company to continue its operations into
1996.  During 1995, the Company generated $6.6 million in license fees and
$1.6 million in product sales. While the Company has exceeded its expectations
to date regarding technology licensing fees, production delays have slowed new
product sales. Operating expenses have been reduced throughout 1995 and were
less than projected in the plan adopted in December of 1994. Success in
generating technology licensing fees, royalties and product sales are
significant and critical to the Company's ability to overcome its present
financial difficulties. 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.

         In January 1996, the Company adopted a plan that management
believes should generate sufficient funds for the Company to continue its
operations into 1997.  Under this plan, the Company needs to generate
approximately $19 million to fund its operations for 1996.  The Company
believes that it can generate these funds from operations in 1996, although
there is no certainty that the Company will achieve this goal.  Included in
such amount is approximately $8.9 million in sales of new products and
approximately $9.0 million of  technology licensing fees and royalties.
Success in generating technology licensing fees, royalties and  product sales
are significant and critical to the Company's ability to overcome its present
financial difficulties.  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 1996, management of the Company determines that it will be
unable to meet or exceed the plan discussed above, the Company will consider
fund raising alternatives.  The Company's ability to raise additional capital
through sales of common stock will be severely limited until the Company's 
stockholders approve an amendment to the Company's Certificate of  
Incorporation authorizing additional capital stock and the termination of the 
one year restriction on further equity financing undertaken by the Company in
connection with the sale of common stock and convertible term notes to three
institutional investors described above.  The Company will monitor its 
performance against the plan on a monthly basis and, if





                                       35
<PAGE>   36
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 1997.

         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 further 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.  The uncertainty 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,
raises substantial doubt about the Company's ability to continue as a going
concern.  Further discussion of these uncertainties is presented in Notes 1. and
15. -  "Notes to the Consolidated Financial Statements".

         Because the Company will not meet its revenue targets for the first
quarter of 1996, it has entered into two recent transactions, which provide
additional funding as follows:   

         On March 28, 1996, the Company sold 2,000,000 shares of its common
stock in a private placement that provided net proceeds to the Company of $0.7
million.

         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.  The conversion of the notes and the exercise
of the options are both subject to stockholder approval of an appropriate
amendment to the Company's certificate of incorporation increasing its
authorized capital to provide for the requisite shares.

         In conjunction with the foregoing sale of common stock and convertible
term notes, the Company also agreed to file a registration statement with the
Securities and Exchange Commission ("SEC") covering the applicable shares and
to use its best efforts to have such registration statement declared effective
by the SEC as soon as practicable.  The relevant agreements provide for
significant monetary penalties in the event such registration statement is not
declared effective within 90 days of the filing date and in the event its
effectiveness is suspended for other than brief permissible periods.  The
agreements also prohibit the Company from concluding any further financing
arrangements which involve the sale of equity or an equity feature without the
investors' consent for a period of one year.

         The total cash received to date by the Company  from the above two
transactions amounts to $2.2 million.  (Refer to "Liquidity and Capital
Resources" above and Notes 1. and 15. - "Notes to the Consolidated Financial 
Statements" below.)

         At December 31, 1995, cash and short-term investments were $1,831,000. 
The available resources were invested in interest bearing money market
accounts.  The Company's investment objective is preservation of capital while
earning a moderate rate of return.
 


                                       36
<PAGE>   37
         The Company's working capital increased from $923,000 at December 31,
1994, to $1,734,000 as of December 31, 1995.  This increase was due primarily
to the 1995 private placements noted above reduced by the net loss for the year
and the reduction in the Walker liability (See Note 3. - "Notes to the
Consolidated Financial Statements.")

         During 1995, the net cash used in operating activities was $5.0
million.  This utilization reflects the emphasis on the commercial development
of its technology into several product applications which were scheduled for
introduction in 1995 and 1996.

         Net inventory declined during 1995 by $423,000, primarily reflecting
sales of the NoiseBuster(TM) product.

         During the year ended December 31, 1995, accounts receivable reserves
were decreased by $782,000 as the Company wrote off certain accounts (see Note
8. - "Notes to the Consolidated Financial Statements").

         The Company's available cash balances at December 31, 1995 are as
projected at the end of 1994, primarily due to cost savings and the private
placements noted above.

         The net cash used in investing activities amounted to $272,000 during
the year primarily for acquisition of patent rights.  The net cash provided by
financing activities amounted to $4,678,000 primarily from the exercise of
options and warrants and the private placements 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 although
the Company's ability to raise additional capital through sales of common stock
will be severely limited until the Company's stockholders approve
an amendment to the Company's Certificate of Incorporation authorizing
additional capital stock and the termination of the one year restriction on
further equity financing undertaken by the Company in connection with the sale
of common stock and convertible term notes to three institutional investors
described above.  


                             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, 1995, and no material commitments are anticipated in the near
future.

"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, 1995, to December 31, 1995,
all filing requirements applicable to its officers, directors, and greater than
10% stockholders





                                       41

were complied with, except that John J. McCloy, II, Co-Chairman of the Board of
Directors, failed to file two Form 4's reporting four transactions.  Such 
transactions were reported on Form 5 which was filed 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, 1995, 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





                                       43


<PAGE>   44
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





                                       44


<PAGE>   45
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,
1995, 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, the Company
made no payments to QSI for project management services.

         In March 1995, the Company entered into an agreement with QSI (see
Note 8, - "Notes to the Consolidated Financial Statements") by which QSI
received the exclusive right 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 agreements
generally provide that the Company manufactures the products and receives a
royalty of 6% from QSI on the sales of the product.  For the exclusive rights
under the agreement, QSI is to pay a license fee to NCT of $750,000, $250,000
of which QSI paid to NCT in June of 1994, and the balance of which is payable
in equal monthly installments of $16,667, beginning in April of 1995.  The
agreement supersedes any other agreements related to the product above.  The
agreement is contingent upon full payment by QSI to NCT of trade receivables,
which at December 31, 1994 amounted to $492,100.  All amounts due from QSI were
fully reserved at December 31, 1995 (See Note 2, - "Notes to the Consolidated
Financial Statements").

         In April 1995, the Company amended the March 1995 agreement with QSI
as follows.  QSI forfeited warrants to purchase 750,000 shares of the Company's
common stock which had been issued pursuant to the May 15, 1993 Marketing
Agreement (Non-retrofit Utility Products) and the $500,000 balance due the
Company for the exclusivity fee was reduced to $250,000.  In addition, accounts
receivable due the Company from QSI were converted to a note receivable from
QSI, bearing annual interest at 6% due May 15, 1996 or earlier contingent upon
the occurrence of certain events.  The note receivable from QSI was fully
reserved at December 31, 1995.





                                       45


<PAGE>   46
         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.

                        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 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 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 circumstances
relating to this fundamental uncertainty are described in note 1.  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 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.

                        REPORT OF INDEPENDENT AUDITORS




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, 1994 and
December 31, 1995, and the related consolidated statements of operations,
stockholders' equity and cash flows for the years then ended.  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 1994 and 1995 financial statements of the 
Company's two foreign subsidiaries.  These subsidiaries accounted for revenues
of approximately $1,800,000 and $1,200,000 for the years ended December 31,
1994 and December 31, 1995, respectively, and assets of approximately 
$1,900,000 and $586,000 at December 31, 1994 and December 31, 1995,
respectively.  These  statements were audited by other auditors whose reports
have been furnished to us, one of which contained a reference to the
uncertainty relating to the Company's ability to continue as a going concern. 
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
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis for our
opinion.

     In our opinion, 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, 1994 and December 31,
1995 and the results of their operations and cash flows for the years then
ended 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 incurred recurring
operating losses and will require additional financing.  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.

                      REPORT OF INDEPENDENT ACCOUNTANTS



We have audited the consolidated statements of operations, stockholders' equity
and cash flows of Noise Cancellation Technologies, Inc. and Subsidiaries for
the year ended December 31, 1993, and the related financial statement schedule  
for the year ended December 31, 1993, listed in the index on page 38 of this
Form 10-K. These financial statements and financial statement schedule are the
responsibility of the Company's management.  Our responsibility is to express
an opinion on these financial statements and financial statements and financial
statement schedule based on our audit.

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

The aforementioned consolidated financial statements and financial statement
schedule have been prepared assuming that the Company would continue as a going
concern.  Our report on our audit of such consolidated financial statements and
financial statement schedule was issued originally under date of March 24,
1994.  Such report was based upon the facts and circumstances as the existed at
that time, including that substantial doubt did not exist as to the Company's
ability to continue as a going concern through December 31, 1994.  Subsequent
to the date of issuance of our original report, certain uncertainties have
arisen as described in "Risk Factors - Current Financial Condition; Cash
Position" appearing in the Company's Current Report on Form 8-K, Item 5, filed
on December 19, 1994.  Such subsequent uncertainties with respect to the
availability of funds to sustain the Company's activities indicate at December
19, 1994, that the Company may be unable to continue as a going concern through
1995.

In our opinion, the financial statements of Noise Cancellation Technologies,
Inc. and Subsidiaries referred to above present fairly, in all material
respects, the consolidated results of their operations and their cash flows for
the year ended December 31, 1993, in conformity with generally accepted
accounting principles.  In addition, in our opinion, the financial statement
schedule referred to above, when considered in relation to the basic financial
statements taken as a whole, present fairly, in all material respects, the
information required to be included therein.

                     NOISE CANCELLATION TECHNOLOGIES, INC.
                       NOTES TO THE FINANCIAL STATEMENTS

1. BACKGROUND:

         Noise Cancellation Technologies, Inc. (the "Company") is engaged in
the design, development, licensing, production and distribution of electronic
systems that actively reduce noise and vibration, principally through joint
ventures and other forms of strategic alliances.  The Company's activities to
date have principally involved the developing of its electronic systems for
commercial use and providing engineering and development services under
contracts with strategic partners and third parties.

         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 $72.8 million on a
cumulative basis through December 31, 1995.  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 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, cash equivalents and short-term investments amount to $1.8
million at December 31, 1995, decreasing from $2.4 million at December 31,
1994. Management does not believe that available funds at December 31, 1995 are
sufficient to sustain the Company for the next twelve months. Management
believes that cash and the cash anticipated from the exercise of warrants and
options, the funding derived from forecasted technology license fees,
royalties, and product sales, and engineering and development revenue, the
operating cost savings from the reduction in employees and





                                     F - 7
<PAGE>   67
reduced capital expenditures should be sufficient to sustain the Company's
anticipated future level of operations into 1997.  However, the period during
1997 through which it can be sustained is dependent upon the level of
realization of funding from technology license fees, royalties and product
sales, and engineering and development revenue and the achievement of the
operating cost savings from the events described above, all of which are
presently uncertain.

         There can be no assurance that additional 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 further and
substantially cut back its level of operations in order to conserve cash.
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 15 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, 1995, 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
wholly 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.





                                     F - 8

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, $249,700 and $605,500 for the years ended December 31, 1995, 1994
and 1993, respectively.  Retainage balances were $8,200 at December 31, 1995
and 1994.  The 1995 balance is expected to be collected within one year.

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 the Walker Noise
Cancellation Technologies and Ultra Electronics, Ltd. transactions.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS:

         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.

         Short-term investments principally comprise high quality investments
in fixed-income securities funds and mid-term, high quality bond funds.

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;
currently this is done on a quarterly basis.  At the same time, the Company
reviews the movement of inventory on an item by item basis to determine the
value of items which are either slow moving or have become obsolete since the
last quarterly review.  After applying the above noted measurement criteria, as
well as looking forward to assess the potential for near term product
engineering changes and/or technological obsolescence, the Company determines
the current need for inventory reserves.  After applying the above noted
measurement criteria at December 31, 1995, the Company determined that a
reserve of $355,000 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.

PATENT RIGHTS:

         Patent rights are stated at cost and are amortized on a straight line
basis over the remaining average life of the patents (ranging from 1 to 15
years).  Amortization expense was $96,900, $166,700 and $398,100 for 1993, 1994
and 1995, respectively.  Accumulated amortization was $676,700 and $1,074,800
at December 31, 1994 and 1995, respectively.

         It is the Company's policy to review its individual patents on a
regular basis to determine whether any event has occurred which could impair
the valuation of 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.

LOSS PER COMMON SHARE:

         The net loss per common share has been determined on the basis of the
weighted average number of shares of common stock outstanding during the
period.  Common





                                   F - 10
<PAGE>   70
stock equivalents (including stock options and warrants) have not been
considered since their effect would be antidilutive.

CONCENTRATIONS OF CREDIT RISK:

         Financial instruments which potentially subject the Company to
concentration of credit risk consist principally of cash and cash equivalents,
short-term investments and trade receivables.  The Company primarily holds its
cash and cash equivalents in two banks. Deposits in excess of federally insured
limits were $1.6 million at December 31, 1995.  Short-term investments are
primarily held in liquid fixed income funds which are invested principally in
high quality government securities.  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 82.4% of revenues during 1995 and 50.8%
of gross accounts receivable at December 31, 1995.  The Company does not
require collateral or other security to support customer receivables.

</TABLE>

         The Company regularly assesses the realizability of its accounts
receivable and performs a detailed analysis of its aged accounts receivable on
no less than a quarterly basis.  When quantifying the realizability of accounts
receivable, the Company takes into consideration the value of receivables in
the 90+ day category, the nature of disputes, if any, and the progression of
conversations and/or correspondence between the Company and customers regarding
the underlying cause for the age of such receivables.  After applying the above
noted measurement criteria as of December 31, 1995, the Company determined that
a reserve of $119,000 was adequate.

RECLASSIFICATIONS:

         Certain reclassifications have been made to the 1993 and 1994
financial statements to conform with the 1995 presentation.





                                    F - 11
<PAGE>   71
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.

RECENT PRONOUNCEMENTS

         In October 1995, the Financial Accounting Standards Board issued SFAS
No. 123,.  "Accounting for Stock-Based Compensation" which is effective for the
Company's 1996 financial statements.  SFAS No. 123 allows companies to either
account for stock-based compensation under the new provisions of SFAS No. 123
or under the provisions of APB No. 25, but requires pro forma disclosure in
the footnotes to the financial statements as if the measurement provisions of
SFAS No. 123 had been adopted.  At this time, the Company intends to continue
accounting for its stock-based compensation in accordance with the provisions
of APB No. 25.  As such, the adoption of SFAS No. 123 will not impact the
financial position or results of operations of the Company.


3. JOINT VENTURES AND OTHER STRATEGIC ALLIANCES:

         The following is a summary of the Company's joint ventures and other
strategic alliances as of December 31, 1995.

         The Company and certain of its wholly-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,
1995, 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, 1995.  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 these ventures
or alliances:

JOINT VENTURES


         Chaplin Patents Holding Company ("CPH") was co-owned on a 50/50 basis
by the Company and ANVT, a former competitor.   On September 16, 1994, the
Company acquired the patents, technology, other intellectual property and
certain related tangible assets of ANVT.  The Company also acquired all rights
under certain joint venture and customer agreements subject to the consent of
the other parties to those agreements.  Included in the acquisition was ANVT's
50% interest in CPH at which time the Company became the sole shareholder of
CPH.  CPH acquired certain patent rights relating to the reduction and
elimination of noise and vibration from the Company, ANVT and a third party.
The Company and ANVT had licensed co-exclusive rights to the Chaplin Patents





                                    F - 13
<PAGE>   73
from CPH.  The joint venture agreement related to the Chaplin Patents required
that the Company may only license or share the related technology with entities
who are affiliates of the Company.  As a result, the Company has established
several joint ventures and formed other strategic alliances 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. Initial
capital contributions by the Company and ANVT of $150,000 each to CPH were used
to acquire certain rights owned by the third party.  Pursuant to the patent
license agreement, and until September 16, 1994 the Company and ANVT
contributed cash equally to CPH to fund administrative costs and provide for
maintenance and protection of the related patents.  After September 16, 1994,
the Company, as sole shareholder of CPH, was responsible for 100% of CPH's
funding requirements. This funding charged to operations by the Company was
$244,000, $345,000 and $596,000 for each of the years in the three year period
ended December 31, 1995, respectively, and is included in general and
administrative expenses in the accompanying Statements of Operations.

         Walker Noise Cancellation Technologies ("WNCT") was a 50/50 general
partnership between NCT Muffler, Inc., a wholly-owned subsidiary of the Company
and Walker Electronic Mufflers, Inc. ("WEM"), a wholly-owned subsidiary of
Tennessee Gas Pipeline Company.  On November 15, 1995, the Company and Walker
executed a series of related agreements (the "Restructuring Agreements") and
concluded previously noted negotiations with Tenneco Automotive and Walker
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 to Walker, the elimination of the Company's
previously expensed obligation to fund the remaining $2.4 million of product
and technology development work noted above, 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. In consideration for the above, Walker paid the Company $0.3
million, delivered to the Company 1,110,083 shares of the Company's common
stock which Tenneco Automotive had purchased from the Company in December 1993
and has undertaken to pay the Company certain royalties from the exploitation
of the intellectual property rights granted to Walker under the expansion of
existing technology licenses.  The shares delivered to the Company were retired
on November 16, 1995.




                                    F - 14
<PAGE>   74
Accordingly, the Company recorded $3.6 million as a technology licensing fee
relating to the net effect of the above noted Restructuring Agreements in the
fourth quarter of 1995.

         WNCT was established in 1989 to develop, manufacture and distribute
active mufflers for use in automobiles and other vehicles and other industrial
applications.  The agreement between NCT and Walker was expanded and extended
in 1991.

         Initial capital contributions by the Company and WEM were $750,000
each, and such amounts were paid by WNCT to the Company as a license fee in
1989.  The joint venture agreement provided that WEM will make preferred
contributions to WNCT for the purpose of funding engineering and development
performed by the Company and engineering performed by WEM.  Aggregate preferred
contributions made by WEM to WNCT (net of return of capital advances to WEM)
through December 31, 1994, amounted to $7.6 million, of which $4.2 million was
paid to the Company and $3.4 million was credited by WNCT to WEM's capital
account for the cost of engineering services performed.  Interest on the
engineering preferred contributions and certain portions of the engineering and
development contributions was compounded monthly at 1% less than the bank prime
rate until repaid through preferred distributions. WEM's obligation to fund
engineering and development expired at the end of the first quarter of 1994.

         The Company recorded income of $750,000 from the license fee in 1989.
The Company has also recorded as income its engineering and development
payments from WNCT, amounting to $1.1 million, $1.1 million and $0.7 million
for each of the years in the three year period ended December 31, 1995,
respectively.  There is no recourse to the Company for these payments.  Other
than certain future Walker funded research and development activities noted
above, the Company has no current plans, obligation or intention to provide
additional funding to WNCT.

         In December, 1993, Tenneco Automotive, a division of Tennessee Gas
Pipeline Company, purchased shares of common stock of the Company for $3.0
million in cash, at a price per share of approximately $2.70, which was equal
to 94% of the price to the public of the shares of the Company's common stock
then offered.  Immediately thereafter, the Company contributed $1.0 million to
the capital of WNCT, following which WNCT repaid $1.0 million of the capital
advances made to WNCT by WEM and representatives of WEM.  The Company agreed to
restructure WNCT.  Such restructuring would include giving WNCT worldwide
rights for the manufacture and sale of all muffler products except those
manufactured and sold in the consumer and defense markets.  WNCT also would be
expanded to have, in addition to rights it has with respect to vehicular
mufflers, worldwide rights to all silencing and vibration applications (e.g.,
mufflers, cabin quieting, engine mounts, fan quieting and engine block
quieting) for all vehicles except trains, aircraft and watercraft.  In
addition, the Company committed to  help fund $4.0 million of product and
technology development work of the Company attributable to WNCT.  Also pursuant
to the agreement with Tenneco Automotive, Walker's right to acquire the
Company's interest in WNCT upon the occurrence of





                                    F - 15
<PAGE>   75
certain events was eliminated and Tenneco Automotive had the right to have a
representative serve on the Company's Board of Directors. The agreement with
Tenneco Automotive and the Company's related funding commitment resulted in
1993 recognition of $3.6 million of previously unrecognized losses and 1994
recognition of $1.4 million of current year losses with respect to the joint
venture with WEM.  Such losses exceeding the Company's remaining investment in
WNCT amounted to $2.9 million at December 31, 1994.  Of the $2.9 million, $1.5
million recorded as a current liability.  The balance of $1.4 million was
classified as a long term liability.  The above noted November 15, 1995
Restructuring Agreements significantly altered the foregoing terms of the
December 1993 agreement.

         Prior to December 31, 1994, the Company's share of cumulative losses
equaled its investment and commitment to the joint venture.  The Company had no
further obligation or intention to fund any additional losses therefore, the
Company suspended applying the equity method.

         Foster/NCT Headsets International, Ltd. ("FNH") was a 50/50 joint
venture between Foster Electric Company, Ltd. ("Foster") and the Company.  FNH
was established as a limited liability company in Japan in March 1991 to
develop, design, manufacture and sell active noise cancellation headset
systems.  FNH had exclusive manufacturing rights for the headsets in the Far
East and non-exclusive marketing rights worldwide.  Additionally, another joint
venture with Foster/NCT Supply, Ltd., ("FNS" as described below) served as a
supply joint venture for FNH.

         On July 28, 1995, Foster Electric Co., Ltd. ("Foster"), Foster NCT
Headsets International ("FNH") and the Company executed a letter agreement
amending the 1991 agreement covering the headset joint venture company, FNH.
Pursuant to that agreement Foster acquired the Company's 50% interest in FNH
and a license to manufacture headsets for FNH and NCT with tooling currently
owned by NCT in consideration for Foster's assumption of FNH's outstanding
liabilities of $303,000. The agreement also grants FNH the right to sell
certain headsets on an exclusive basis in Japan and a non-exclusive basis
throughout the rest of the Far East, in consideration for a royalty on the sale
of such headsets.

         Initial capital contributions made by the Company and Foster under the
FNH joint venture agreement were 6.5 million yen (historical cost of
approximately $47,000) each.  In March, 1994 the Company and Foster agreed to
jointly and equally increase the capitalization of FNH to a total of 52 million
yen resulting in the Company's additional investment of $191,000.  The increase
in capitalization enabled FNH to launch an expanded marketing effort in the
Company's products in the Far East.

         Under related agreements, Foster paid a license fee to the Company of
$1 million, which was recognized as income in 1991, and agreed to pay an
additional $700,000 to the Company at a rate of two percent of sales after
cumulative sales by FNH reach $50





                                    F - 16
<PAGE>   76
million and the accumulated deficit in FNH is reduced to zero.  The license
fees paid to date in the amount of $1.0 million are not subject to repayment.

         As part of the February 10, 1995 agreement to desolve the FNS joint
venture, (see FNS Note below) NCT has repurchased the exclusive manufacturing
rights for headsets in the Far East from Foster.  The Company recorded a charge
of $780,000 in 1994 relating to these transactions.

         In return for technical and management assistance provided by Foster,
FNH has agreed to pay Foster up to an aggregate amount of $1.4 million based on
three percent of sales; the first $700,000 of which are to be paid without
restriction based upon sales amount, the remaining $700,000 begin to be paid to
Foster when the FNH accumulated deficit is reduced to zero.  Through December
31, 1994, the accumulated deficit of FNH was $543,000.

         The Company's above noted incremental investment resulted in the
recognition of $42,000 of previously unrecognized losses and $149,000 of
current losses with respect to the FNH joint venture in 1994.

         The Company has purchased certain tooling for use by FNH which it has
recorded on its books. The tooling will be amortized against products sold by
NCT.

         Analog/NCT Supply Ltd. ("ADI/NCT") is a 50/50 joint venture between
Analog Devices, Inc. ("ADI") and the Company which was established in June
1992.  ADI/NCT was formed to design, develop and manufacture computer chips to
be incorporated into the Company's electronic systems.  Initial capital
contributions by the Company and ADI were nominal.  The joint venture and
related agreements provide that each party will bear their respective cost of
design and development of the computer chips.  ADI will manufacture and sell
the computer chips to ADI/NCT, based on orders provided to ADI/NCT by the
Company, at prices to be agreed upon by the Company and ADI.  Administrative
services required by ADI/NCT will be provided by ADI, the costs of which will
be funded by the joint venture. No such services have been charged to or
incurred by the joint venture as of December 31, 1995.

         Harris/NCT Supply, L.L.C. ("HARNCT") is a 50/50 limited liability
company owned equally by Harris Corporation ("Harris") and the Company under a
Limited Liability Company Agreement concluded in September, 1993 (the "LLC
Agreement").  HARNCT will develop and manufacture silicon chips to be
incorporated into the Company's electronic systems. Initial capital
contributions by the Company and Harris were nominal.  The LLC Agreement
provides that each party will bear their respective cost of design and
development of the silicon chips. Harris will manufacture and sell the silicon
chips to HARNCT, based on orders provided to HARNCT by the Company, at prices
to be agreed upon by the Company and Harris.  Administrative services required
by HARNCT will be provided by Harris, the costs of which will be funded by
HARNCT.





                                    F - 17
<PAGE>   77
No such services have been charged to or incurred by HARNCT as of December 31,
1995.

         OnActive Technologies, L.L.C. ("OAT") is a 50/50 limited liability
company owned equally by Applied Acoustic Research, L.L.C. ("AAR") and the
Company ("Members") under an Operating Agreement concluded in December, 1995.
OAT will design, develop, manufacture, market, distribute and sell flat panel
transducers 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 neither Member is required to make any
additional contribution to OAT.  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.  Administrative services required by
OAT will be provided by the Company, the costs of which will be funded by OAT.
Such services for the period ended December 31, 1995 were nominal and not
charged to OAT.  As of December 31, 1995 the Company recognized $80,000 of
income relating to its share of 1995 profit in OAT.

         Foster/NCT Supply, Ltd., ("FNS") was a 30/70 joint venture between the
Company and Foster which was established in June 1991 to serve as a supply
joint venture for the Company's worldwide activities.

         Foster and the Company have agreed that the acquisition of certain
assets of ANVT by NCT (see Note 14) has removed the necessity for the continued
existence of FNS.  An orderly liquidation of FNS was completed in April 1995.
The agreement provided for the Company's repurchase from Foster for $0.6
million of the exclusive headset manufacturing rights in the Far East (see FNH
note above) and an immediate minimum 5% reduction in the price of headset
products to be produced by Foster for the Company.  The Company accrued a $0.8
million charge in 1994 relating to this agreement, of which $0.2 million was
reflected as a current liability at December 31, 1994.

         Capital contributions required under the joint venture agreement were
3 million yen from the Company and 7 million yen from Foster (approximately
$22,000 and $51,000, respectively).  Foster was also required to provide
assistance to FNS for research and development activities amounting to $50,000
per month up to an aggregate of $1.2 million, which FNS was to repay to Foster
at the rate of one percent of the amount of each month's sales.  There was no
recourse to the Company should FNS not record sufficient sales for Foster to
recover such research and development costs.

         Boet Systeme Actif S.A. ("BSA") was a 49/51 joint venture between NCT
Muffler, Inc., a wholly-owned subsidiary of the Company, and S.A. Andre Boet
("Boet"), respectively.  BSA was established in 1991 to develop, manufacture in
France, and sell worldwide NCT electronic silencers for use on non-automotive
internal combustion engines.  BSA was responsible for the customization,
marketing and sales of the silencers.  The Company was to assist BSA with
product development and employee





                                    F - 18
<PAGE>   78
training.  All supplies were to be purchased by BSA from either Boet or NCT
Muffler. Initial capital contributions by NCT Muffler and Boet were not
significant.

         As a result of the April 1994 transfer to WNCT of the rights to market
the Company's industrial silencer products and anticipation of the Company's
November 15, 1995 agreement with Tenneco Automotive and Walker (see WNCT Note
above), in October, 1995 Boet assumed all liabilities of BSA and the Board of
Directors of BSA approved the dissolution of the joint venture.

         BSA funded the Company's cost of research and engineering, at a
predetermined rate, and reimbursed materials, equipment, tools, supplies and
out-of-pocket expenses to Boet and the Company. The joint venture agreement
provided that Boet would advance funding for the development, operation and
working capital needs of BSA. BSA was to repay Boet through preferential
distributions from its excess cash in amounts not to exceed 20% of BSA's net
income in each year.  Boet contributed an aggregate of approximately $496,000
to BSA through December 31, 1994, none of which was repaid.

         Payments from BSA to the Company for research and engineering
aggregated approximately $120,000 through December 31, 1994.  License fees from
BSA to NCT Muffler aggregated $240,000 through December 31, 1994.  The above
amounts were recognized as income by the Company since there was no commitment
or intention for NCT Muffler to fund any obligations of BSA, nor was there any
recourse to NCT Muffler for these payments.

         Philips NCT Noise Cancellation N.V. ("PNNC") was established in
August, 1992 to develop and manufacture components for active noise and
vibration control systems and sell such components to the Company or the
Company's customers.  In July 1993, the Company and its co-venturer, Philips
Industrial Activities N.V. ("PIA") decided to suspend business operations of
the joint venture until such time as the nature, specifications and volume of
components required by the Company from PNNC become more clearly defined.
Subsequently, in December 1993, the Company sold its entire interest in PNNC to
PIA for a nominal fee, and PIA assumed all obligations of PNNC.  The Company
and PIA continue to pursue mutual business interests.

OTHER STRATEGIC ALLIANCES:

         Foster and the Company entered into an agreement in December 1993,
pursuant to which Foster purchased shares of common stock at a value of $2.0
million (the "Foster Shares"), at a price per share of approximately $2.70
equal to 94% of the price to the public of the shares of common stock in the
December 1993 offering.  Foster paid the purchase price by means of a cash
payment of one cent ($.01) per share (the par value of the common stock) and
the delivery of a series of promissory notes (the "Foster Notes") in an
aggregate principal amount equal to the balance of the purchase price. The
Foster Notes were full recourse notes of Foster bearing interest at one percent
above the rate of three-year United States Treasury Notes and were to mature on
April 17, 1997.  The Foster Notes were secured by the Foster Shares until paid
or "earned out" as described in the next paragraph.  The Foster Notes were
recorded as a Common Stock subscription receivable by the Company.

         Foster and the Company entered into an agreement under which Foster
provided and the Company will purchased $2.0 million of various product and
market development services deemed necessary by the Company for
commercialization of several new headset and other products and the further
development of the Company's Japanese markets.  Upon completion of each such
project or phase, the agreed budgeted amount therefore was billed to the
Company and paid, at the Company's election, either in cash or by discharge of
an equivalent amount of the Foster Notes, in which an appropriate number of the
Foster Shares were released from the collaterlization restrictions and the
Common Stock subscription receivable was reduced.  During 1995, $1.3 million of
such services and assets were purchased by the Company and, at the Company's
election was satisfied through the discharge of an equivalent amount of the
Foster Notes.  As of December 31, 1995, the Foster Notes have been
paid-in-full.

         Foster and the Company's wholly owned subsidiary, NCT Far East
("NCTFE") entered into a marketing agreement in November 1991 under which
Foster agreed to fund up to $500,000 for the establishment of a marketing
office in Tokyo.  This funding was reimbursed through the issuance of 150,000
shares of common stock of the Company to Foster in 1992 and future payments to
Foster by NCTFE equal to 25% of NCTFE pretax profits, as defined, until Foster
has recovered 100% of funding in excess of $300,000.  The market value of the
Company's common stock issued to Foster ($300,000) was charged to operations in
1992.  Through December 31, 1995, $185,200 has been funded by Foster under the
marketing agreement.  Further, commissions payable by NCTFE to Foster under
this agreement are based upon sales by customer and 5% of any engineering and
development or working capital funding acquired through Foster's efforts.

         Interkeller AG ("Interkeller"), a member of Rieter Holding Limited,
and the Company entered into a strategic alliance in June 1992 to improve the
noise reduction in vehicles through the combination of NCT's active cabin
quieting system ("ACQS") and Interkeller technology.  Under the agreement,
Interkeller performed acoustic studies in the field of electronic cabin
quieting in vehicles, and the Company sold Interkeller a prototype ACQS and
licensed Interkeller the right to use related software in connection with
acoustic studies under the agreement, for which Interkeller has paid a license
fee and contributed $240,000 to the Company over a two year period, ending June
1994. As of December 31, 1994, the Company has recognized cumulative license
fee income of $180,000 and $97,000 for consultation and development under the
June 1992 agreement.  The contract has not been renewed.

         AB Electrolux ("Electrolux") and the Company entered into a Joint
Development Cooperation Agreement in June 1991 which provides for the Company
to design, develop and supply active systems for quieting certain Electrolux
products.  Electrolux agreed to pay the Company $65,000 per month for two
years, which the Company has recorded as engineering and development income.
These development costs may be recovered by Electrolux through royalties on net
sales to other manufacturers of competing products up to 250% of the
engineering and development costs funded by Electrolux. Electrolux agreed to
purchase components for the manufacture of related systems for its products
from the Company.  If Electrolux purchases such components from other sources,
a royalty of 6% of the net invoice price will be due to the Company.

         Further, the Company granted Electrolux a worldwide non-exclusive
license to utilize related proprietary technology for the life of such patents
for a fee of $500,000 payable in monthly installments of $20,000, and agreed to
limit the Company's licensing of such technology to five white goods
manufacturers for a period of five years.  In January 1994 such limitations on
the Company's technology licensing were terminated by an amendment to the
original agreement.  The $500,000 license fee was recognized as income in 1991,
all of which was paid as of December 31, 1993.

         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.

         Siemens Medical Systems, Inc. ("Siemens") and NCT Medical Systems,
Inc. ("NCTM"), a 90%-owned subsidiary of the Company, entered into an agreement
in March 1992 to supply Siemens with NCTM/MRI systems, a noise cancellation and
audio system for Magnetic Resonance Imaging systems ("MRI"), on an exclusive
basis at specified quantities over two years.  In return, Siemens has agreed to
utilize only NCTM/MRI systems in their MRI's during the two year period.
During 1993, 1994 and 1995 NCTM has sold 118, 48 and 26 units, respectively, to
Siemens.   In late November 1993, the Company and Siemens signed a new
agreement, superseding the 1992 agreement, which provides for the purchase by
Siemens from the Company of European and U.S. versions of the Company's MRI
headsets suitable for use with Siemens' MRI machines.

         Bosch-Siemens Hausgerate GmbH ("BSHG") and the Company entered into a
one year agreement in April 1992 for the Company to perform research and
development work to enhance BSHG products with NCT technology.  As of December
31, 1993, the Company had completed the required work.  In accordance with the
agreement, BSHG has paid a total of $780,000, of which $260,000 was recorded as
income in 1993.

On October 6, 1992, the Company adopted a stock option plan (the "1992 Plan")
for the granting of options to purchase up to 1,639,865 shares of common stock
to officers, employees and certain directors and on that date granted options
on 1,357,989 shares at a price of $2.375 under the plan. On April 14, 1993, the
Company amended the plan to provide for the granting of options and restricted
stock awards covering up to an additional 4,360,135 shares of common stock to
officers, employees and non-employee directors.  The exercise price of all
options granted under the plan may not be less than the market value of a share
of common stock on the date of grant.  On May 27, 1993, the plan and the grants
received stockholder approval at the 1993 Annual Meeting of Stockholders.  At
December 31, 1995, options for 3,235,026 shares are outstanding, of which
1,534,355 are exercisable under this plan at prices ranging from $.656 to
$4.00.

         In 1993, the Company issued warrants to purchase 750,000 of the
Company's common stock to a company as part of a marketing agreement (see Note
8) and 250,000 warrants to an outside consultant as part of a consulting
agreement.  In 1994, the Company issued warrants to purchase 89,000 shares of
the Company's common stock to outside consultants as part of their consulting
agreements.

         In 1995, the Company issued 2,144,750 at market value currently
unexercisable warrants to certain directors and officers.  These new
unexercisable warrants were equal to 115% of 1,865,000 warrants forfeited to
enable the Company to assemble sufficient shares of common stock to complete
the 1995 private placements (see Note 6).  The 15% increase in the number of
replacement vs.  forfeited warrants was in consideration for the
unexercisability of the in-the-money replacement shares until such time there
are a sufficient quantity of shares available to cover the exercise of the
subject warrants.  Also in 1995, the Company similarly issued 274,000 at market
value currently unexercisable warrants to purchase shares of the Company's
common stock to two outside consultants who forfeited an equivalent number of
out-of-the money warrants for the purpose noted above.

8. RELATED PARTIES:

         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





                                    F - 28

<PAGE>   88
(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,
1995, 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, 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.





                                    F - 29

<PAGE>   89
         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, 1995, 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, the Company
made no payments to QSI.

         In March, 1995, the Company entered into an agreement with QSI by
which QSI received the exclusive right 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
agreements generally provide that the Company manufactures the products and
receives a royalty of 6% from QSI on the sales of the product.  For the
exclusive rights under the agreement, QSI is to pay a license fee to NCT of
$750,000, $250,000 of which QSI paid to NCT in June of 1994, and the balance of
which is payable in equal monthly installments of $16,667, beginning in April
of 1995.  The agreement supersedes any other agreements related to the product
above.  The agreement is contingent upon full payment by QSI to NCT of trade
receivables, which at December 31, 1994 amounted to $492,100.  All amounts due 
from QSI were fully reserved at December 31, 1995 (See Note 2).

         In April, 1995, the Company amended the March, 1995 agreement with QSI
as follows.  QSI forfeited warrants to purchase 750,000 shares of the Company's
common stock which had been issued pursuant to the May 15, 1993 Marketing
Agreement (Non-retrofit Utility Products) and the $500,000 balance due the
Company for the exclusivity fee was reduced to $250,000.  In addition, accounts
receivable due the Company from QSI were converted to a note receivable from
QSI, bearing annual interest at 6% due May 15, 1996 or earlier contingent upon
the occurrence of certain events.  The note receivable from QSI was fully
reserved at December 31, 1995.

         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.

         During 1993, 1994 and 1995, the Company purchased $2.1 million, $2.2
million and $0.5 million respectively, of products from its various
manufacturing joint venture entities of which $0.3 million was included in
accounts payable at December 31, 1994.  There were no accounts payable related
to manufacturing joint venture entities at December 31, 1995 reflecting the
termination or transfer of ownership of the subject ventures in 1995 (see Note
3).

         As discussed in Note 6, the Company had stock subscription receivables
from an officer and a director in 1993, a joint venture partner in 1993 and
1994 and a former director in 1995.

9. INCOME TAXES:

         On January 1, 1993, the Company adopted 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, reserves and equity in
losses of unconsolidated affiliates. The adoption of the aforementioned
accounting standard had no effect on previously reported results of operations.

         At December 31, 1995, the Company had available net operating loss
carryforwards of approximately $58.7 million and research and development
credit carryforwards of $1.2 million for federal income tax purposes which
expire as follows:

         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 $5,883,600 and $1,395,000 in 1994 and
1995, 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, 1994,  and 1995 were as follows:

10. LITIGATION:

         On September 17, 1992, Harris Landgarten, a former officer and
director of the Company filed suit against the Company in the United States
District Court for the Southern District of New York claiming that the Company
breached contractual promises with him and that the Company fraudulently
deprived him of certain securities. The operative amended complaint demanded
actual damages of approximately $3 million and punitive damages of $5 million.
At the conclusion of the trial on May 1, 1995, the jury returned a verdict in
favor of the Company with respect to two claims, for fraud and breach of
contract, for which Landgarten sought the most damages. On a claim of
non-payment of a consulting fee, the jury awarded Landgarten $104,000. The jury
also rendered an advisory verdict in favor of Landgarten for $35,000 on a claim
of unjust enrichment. On July 26, 1995, the Company and Landgarten executed a
settlement agreement pursuant to which the company paid Landgarten $125,000 and
the suit was dismissed with prejudice.

         As previously disclosed, Chaplin Patents Holding Company, Inc.("CPH"),
a wholly owned subsidiary of the Company, had sued Lotus Cars Limited and Group
Lotus Limited (collectively "Lotus") in Patents County Court in the United
Kingdom for infringement of certain of the Chaplin Patents. On July 13, 1995,
CPH, the Company and Lotus executed a settlement agreement pursuant to which
the action against Lotus and the counterclaims against CPH and the Company were
withdrawn and not to be re-commenced, Lotus was granted a non-exclusive license
for various applications in the land and water based vehicular field, subject
to prior rights, with respect to the three Chaplin Patents that were the
subject of the suit, and CPH paid pound sterling 125,000 (approximately
$190,000) to Lotus, which amount had previously been transferred to the Court
and was being held as security for costs.

         On June 22, 1995, Wilhelm & Dauster, a German law firm, commenced a
suit against the Company in the United States District Court for the District
of Maryland, Southern Division, to recover $125,000 claimed to be owed by the
Company to that firm for legal services, disbursements and costs rendered to
and incurred on behalf of the Company with respect to intellectual property
matters in Europe.  On December 13, 1995, all amounts due Wilhelm & Dauster
relating to the $125,000 claim were paid in full and the suit was subsequently
withdrawn.

         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 Lira ($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 Lira ($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. 
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 judgement against the Company, said
judgement could have a severe material effect on quarterly or annual operating
results.

13.  ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES:

         On January 1, 1994, the Company adopted Statement of Financial
Accounting Standards No. 115, (SFAS No. 115) "Accounting for Certain
Investments in Debt and Equity Securities."  SFAS No. 115 prescribes the
accounting and reporting for investments in equity securities that have readily
determinable fair values and for all investments in debt securities.  The
Company has classified its investments, consisting of a portfolio of short term
U.S. Treasury Bills and related investments, as trading securities which are
reported at fair market value.  The cumulative effect of adoption of the new
standard as of January 1, 1994, is not material.  During the twelve month
period ended December 31, 1994, the Company recorded charges totaling $375,200
relating to realized and unrealized losses in its investments.  No such charge
was incurred in 1995.  Interest income from investments was $587,500 and
$53,000 for the twelve months ended December 31, 1994 and 1995 respectively.


14.  ACQUISITION OF CERTAIN ANVT ASSETS:

         On September 16, 1994, the Company acquired the patents, technology,
other intellectual property and certain related tangible assets of ANVT.  The
Company also acquired all rights under certain joint venture and customer
agreements subject to the consent of the other parties to those agreements.

         Under the acquisition agreement, the Company paid $200,000 plus
2,000,000 shares of its common stock resulting in a total purchase price of
$2,400,000.  In addition, ANVT is entitled to a future contingent earn-out
based on revenues generated by the ANVT contracts assigned to the Company as
well as certain types of agreements to be entered into by the Company with
parties previously having a business relationship with ANVT.  Future contingent
payments, if any, will be charged against the associated revenues.  Companies
that were parties to agreements with ANVT on the closing date include Fiat CIEI
S.p.A. (a Fiat/Gilardini affiliate), Alpine Electronics, Inc., Applied Acoustic
Research, Inc., GEC-Marconi Avionics Limited and Arvin Industries, Inc.  As of
the period ended December 31, 1995, no such contingent earn-out or
payments were due ANVT.

         The shares of common stock issued to ANVT were valued at the average

         The Company allocated $500,000 to in-process research and development
projects, resulting in a corresponding charge to the Company's operations in
1994.

         The patents are being amortized over their respective remaining lives,
which at the time of acquisition ranged from one to seventeen years.


15.  SUBSEQUENT EVENTS

         On March 28, 1996, the Company sold 2,000,000 shares of its common
stock in a private placement that provided net proceeds to the Company of $0.7
million.

         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.  The conversion of the notes and the exercise
of the options are both subject to stockholder approval of an appropriate
amendment to the Company's certificate of incorporation increasing its
authorized capital to provide for the requisite shares.

         In conjunction with the foregoing sale of common stock and convertible
term notes, the Company also agreed to file a registration statement with the
Securities and Exchange Commission ("SEC") covering the applicable shares and
to use its best efforts to have such registration statement declared effective
by the SEC as soon as practicable.  The relevant agreements provide for
significant monetary penalties in the event such registration statement is not
declared effective within 90 days of the filing date and in the event its
effectiveness is suspended for other than brief permissible periods.  The
agreements also prohibit the Company from concluding any further financing
arrangements which involve the sale of equity or an equity feature without the
investors' consent for a period of one year.

         The total cash received to date by the Company  from the above two
transactions amounts to $2.2 million.  (Refer to "Liquidity of Capital
Resources" above and Notes 1. and 15. - "Notes to the Consolidated Financial 
Statements" below.)

             (Incorporated under the laws of the State of Delaware)

         VOID AFTER 5:00 P.M., NEW YORK CITY TIME, ON DECEMBER 31, 1997

                                                     Warrant to Purchase 862,500
                                                     Shares of Common Stock

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

No. BW-1-R

     FOR VALUE RECEIVED, NOISE CANCELLATION TECHNOLOGIES, INC. (the "Company"),
a Delaware corporation, hereby certifies that JOHN J. MCCLOY II (the "Holder")
is entitled, subject to the provisions of this Warrant (the "Warrant"), to
purchase from the Company, at any time, or from time to time, during the period
commencing at 9:00 a.m., New York City local time, on the First Exercise Date
(as hereinafter defined), and expiring, unless earlier terminated as
hereinafter provided, at 5:00 p.m., New York City local time on the Last
Exercise Date (as hereinafter defined), up to 862,500  fully paid and
nonassessable shares of Common Stock, $.01 par value, of the Company at a price
of $0.75 per share (such exercise price per share, as so adjusted, being
hereinafter referred to as the "Exercise Price") provided the Holder has
surrendered and forfeited to the Company a warrant or warrants having an
exercise price or prices of $0.75 or higher owned by Holder and entitling the
Holder to purchase 750,000 shares of Common Stock of the Company.

     The term "Common Stock" means the shares of Common Stock, $.01 par value,
of the Company as constituted on November 8, 1995, the date of grant of this
Warrant (the "Base Date"), together with any other equity securities that may
be issued by the Company in addition thereto or in substitution therefor.  The
number of shares of Common Stock to be received upon the exercise of this
Warrant may be adjusted from time to time as hereinafter set forth.  The shares
of Common Stock deliverable upon such exercise, and as adjusted from time to
time, are hereinafter sometimes referred to as "Warrant Stock".

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver a new Warrant of like tenor and date.  Any such new
Warrant executed and delivered shall constitute an additional contractual
obligation on the part of the Company, whether or not this Warrant so lost,
stolen, destroyed or mutilated shall be at any time enforceable by anyone.
<PAGE>   2
     The Holder agrees with the Company that this Warrant is issued, and all
the rights hereunder shall be held, subject to all of the conditions,
limitations and provisions set forth herein.

     1.   EXERCISE OF WARRANT.  This Warrant may be exercised in whole or in
part at any time, or from time to time, during the period commencing at 9:00
a.m., New York City local time, on the First Exercise Date (as hereinafter
defined), and expiring at 5:00 p.m., New York City local time, on the Last
Exercise Date (as hereinafter defined), or, if such day is a day on which
banking institutions in the City of New York are authorized by law to close,
then on the next succeeding day that shall not be such a day.

     The First Exercise Date shall be the date on which both of the following
events have occurred:

     (a)  an amendment to the Company's Certificate of Incorporation increasing
by at least 5,000,000 shares the number of shares of Common Stock of the
Company that the Company is authorized to issue is approved by the Company's
stockholders and filed in the office of the Secretary of the State of Delaware;
and

     (b)  appropriate corporate action is taken by the Company to reserve
shares of Common Stock of the Company for issuance upon the exercise of this
Warrant.

     The Last Exercise Date shall be December 31, 1997 or ninety (90) days
after the First Exercise Date, whichever shall last occur.

     Subject to the foregoing limitations, this warrant may be exercised by
presentation and surrender hereof to the Company at its principal office, or at
the office of its stock transfer agent, if any, with the Warrant Exercise Form
attached hereto duly executed and accompanied by payment (either in cash or by
certified or official bank check, payable to the order of the Company) of the
Exercise Price for the number of shares specified in such Form and instruments
of transfer, if appropriate, duly executed by the Holder or his or her duly
authorized attorney.  If this Warrant should be exercised in part only, the
Company shall, upon surrender of this Warrant for cancellation, execute and
deliver a new Warrant evidencing the rights of the Holder thereof to purchase
the balance of the shares purchasable hereunder.  Upon receipt by the Company
of this Warrant, together with the Exercise Price, at its office, or by the
stock transfer agent of the Company at its office, in proper form for exercise,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer
books of the Company shall then be closed or that certificates representing
such shares of Common Stock shall not then be actually delivered to the Holder.
The Company shall pay any and all documentary stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of shares of Common
Stock on exercise of this Warrant.

     2.   RESERVATION OF SHARES.  Until the First Exercise Date, no shares of
Common Stock will be reserved for issuance upon the exercise of this Warrant.
Thereafter, the Company will at all times reserve for issuance and delivery
upon exercise of this Warrant all shares of Common Stock or other shares of
capital stock of the Company (and other securities and property) from time to
time receivable upon exercise of this Warrant.  All such shares (and other
securities and property) shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and nonassessable and free of all
preemptive rights.

     3.   WARRANT STOCK TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.
The Warrant Stock may not be sold or otherwise disposed of except as follows:
(1) prior to registration under the Securities Act of 1933, as amended (the
"Act") to a person who, in the opinion of counsel to the Company, is a person
to whom such Warrant Stock may legally be transferred without registration and
without the





                                                                               2
<PAGE>   3
delivery of a current prospectus under the Act with respect thereto or other
disposition of such securities; or (2) upon registration, if ever, under the
Act of the Warrant Stock, to any person upon delivery of a prospectus then
meeting the requirements of the Act relating to such securities and the
offering thereof for such sale or disposition, and thereafter to all successive
assignees unless in the opinion of Counsel to the Company the delivery of such
a prospectus is not required.

     4.   FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant, but the
Company shall issue one additional share of its Common Stock in lieu of each
fraction of a share otherwise called for upon any exercise of this Warrant.

     5.   EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.  This Warrant is
not registered under the Act nor under any applicable state securities law or
regulation.  This Warrant cannot be exchanged, transferred or assigned
otherwise than by will or the laws of descent and distribution, or due to the
Holder's mental or physical incapacity and appointment of a legal guardian as a
result thereof. Upon such event and upon surrender of this Warrant to the
Company or at the office of its stock transfer agent, if any, with the
Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the heir, devisee or assignee named in such instrument
of assignment and this Warrant shall promptly be canceled.  This Warrant may be
divided or combined with other Warrants that carry the same rights upon
presentation hereof at the office of the Company or at the office of its stock
transfer agent, if any, together with written notice specifying the names and
denominations in which new Warrants are to be issued and signed by the Holder
or his executor, administrator or guardian.

     6.   RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

     7.   REDEMPTION.  This Warrant is not redeemable by the Company.

     8.   ANTI-DILUTION PROVISIONS.

          8.1  ADJUSTMENT FOR DIVIDENDS IN OTHER SECURITIES, PROPERTY, ETC.;
RECLASSIFICATION, ETC.  In case at any time or from time to time after the Base
Date the holders of Common Stock (or any other securities at the time
receivable upon the exercise of this Warrant) shall have received, or on or
after the record date fixed for the determination of eligible stockholders,
shall have become entitled to receive without payment therefor: (a) other or
additional securities or property (other than cash) by way of dividend, (b) any
cash paid or payable except out of earned surplus of the Company at the Base
Date as increased (decreased) by subsequent credits (charges) thereto (other
than credits in respect of any capital or paid-in surplus or surplus created as
a result of a revaluation of property) or (c) other or additional (or less)
securities or property (including cash) by way of stock-split, spin-off,
split-up, reclassification, combination of shares or similar corporate
rearrangement, then, and in each such case, the Holder of this Warrant, upon
the exercise thereof as provided in Section 1, shall be entitled to receive the
amount of securities and property (including cash in the cases referred to in
clauses (b) and (c) above) which such Holder would hold on the date of such
exercise if on the Base Date it had been the holder of record of the number of
shares of Common Stock (as constituted on the Base Date) subscribed for upon
such exercise as provided in Section 1 and had thereafter, during the period
from the Base Date to and including the date of such exercise, retained such
shares and/or all other additional (or less) securities and property (including
cash in the cases referred to in clauses (b) and (c) above) receivable by it as
aforesaid during such period, giving effect to all adjustments called for
during such period by Section 8.2.





                                                                               3
<PAGE>   4
          8.2  ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.  In
case of any reorganization of the Company (or any other corporation, the
securities of which are at the time receivable on the exercise of this Warrant)
after the Base Date or in case after such date the Company (or any such other
corporation) shall consolidate with or merge into another corporation or convey
all or substantially all of its assets to another corporation, then, and in
each such case, the Holder of this Warrant upon the exercise thereof as
provided in Section 1 at any time after the consummation of such
reorganization, consolidation, merger or conveyance, shall be entitled to
receive, in lieu of the securities and property receivable upon the exercise of
this Warrant prior to such consummation, the securities or property to which
such Holder would have been entitled upon such consummation if such Holder had
exercised this Warrant immediately prior thereto, all subject to further
adjustment as provided in Section 8.1; in each such case, the terms of this
Warrant shall be applicable to the securities or property receivable upon the
exercise of this Warrant after such consummation.

          8.3  CERTIFICATE AS TO ADJUSTMENTS.  In each case of an adjustment in
the number of shares of Common Stock (or other securities or property)
receivable on the exercise of the Warrant, the Company at its expense will
promptly compute such adjustment in accordance with the terms of the Warrant
and prepare a certificate setting forth such adjustment and showing in detail
the facts upon which such adjustment is based, including a statement of (a) the
consideration received or to be received by the Company for any additional
shares of Common Stock issued or sold or deemed to have been issued or sold,
(b) the number of shares of Common Stock outstanding or deemed to be
outstanding, and (c) the pro forma adjusted Exercise Price.  The Company will
forthwith mail a copy of each such certificate to each holder of the Warrant.

          8.4  NOTICES OF RECORD DATE, ETC.

               In case:

               (a) the Company shall take a record of the holders of its Common
Stock (or other securities at the time receivable upon the exercise of the
Warrant) for the purpose of entitling them to receive any dividend (other than
a cash dividend) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities,
or to receive any other right; or

               (b) of any capital reorganization of the Company (other than a
stock split or reverse stock split), any reclassification of the capital stock
of the Company, any consolidation or merger of the Company with or into another
corporation (other than a merger for purposes of change of domicile) or any
conveyance of all or substantially all of the assets of the Company to another
corporation; or

               (c) of any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, then, and in each such case, the Company shall mail
or cause to be mailed to each holder of the Warrant at the time outstanding a
notice specifying, as the case may be, (i) the date on which a record is to be
taken for the purpose of such dividend, distribution or right, and stating the
amount and character of such dividend, distribution or right, or (ii) the date
on which such reorganization, reclassification, consolidation, merger,
conveyance, dissolution, liquidation or winding-up is to take place, and the
time, if any, is to be fixed, as to which the holders of record of Common Stock
(or such other securities at the time receivable upon the exercise of the
Warrant) shall be entitled to exchange their shares of Common Stock (or such
other securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up. Such notice





                                                                               4
<PAGE>   5
shall be mailed at least twenty (20) days prior to the date therein specified
and the Warrant may be exercised prior to said date during the term of the
Warrant no later than five (5) days prior to said date.

     9.   LEGEND.  In the event of the exercise of any of the Warrants and the
issuance of any of the shares thereunder, prior to the registration of such
shares under the Act, all certificates representing shares shall bear on the
face thereof substantially the following legends, insofar as is consistent with
Delaware law:

             (Incorporated under the laws of the State of Delaware)

         VOID AFTER 5:00 P.M., NEW YORK CITY TIME, ON DECEMBER 31, 1997

                                                     Warrant to Purchase 862,500
                                                     Shares of Common Stock

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

No. BW-2-R

     FOR VALUE RECEIVED, NOISE CANCELLATION TECHNOLOGIES, INC. (the "Company"),
a Delaware corporation, hereby certifies that MICHAEL J. PARRELLA (the
"Holder") is entitled, subject to the provisions of this Warrant (the
"Warrant"), to purchase from the Company, at any time, or from time to time,
during the period commencing at 9:00 a.m., New York City local time, on the
First Exercise Date (as hereinafter defined), and expiring, unless earlier
terminated as hereinafter provided, at 5:00 p.m., New York City local time on
the Last Exercise Date (as hereinafter defined), up to 862,500 fully paid and
nonassessable shares of Common Stock, $.01 par value, of the Company at a price
of $0.75 per share (such exercise price per share, as so adjusted, being
hereinafter referred to as the "Exercise Price") provided the Holder has
surrendered and forfeited to the Company a warrant or warrants having an
exercise price or prices of $0.75 or higher owned by Holder and entitling the
Holder to purchase 750,000  shares of Common Stock of the Company.

     The term "Common Stock" means the shares of Common Stock, $.01 par value,
of the Company as constituted on November 8, 1995, the date of grant of this
Warrant (the "Base Date"), together with any other equity securities that may
be issued by the Company in addition thereto or in substitution therefor.  The
number of shares of Common Stock to be received upon the exercise of this
Warrant may be adjusted from time to time as hereinafter set forth.  The shares
of Common Stock deliverable upon such exercise, and as adjusted from time to
time, are hereinafter sometimes referred to as "Warrant Stock".

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver a new Warrant of like tenor and date.  Any such new
Warrant executed and delivered shall constitute an additional contractual
obligation on the part of the Company, whether or not this Warrant so lost,
stolen, destroyed or mutilated shall be at any time enforceable by anyone.
<PAGE>   2
     The Holder agrees with the Company that this Warrant is issued, and all
the rights hereunder shall be held, subject to all of the conditions,
limitations and provisions set forth herein.

     1.   EXERCISE OF WARRANT.  This Warrant may be exercised in whole or in
part at any time, or from time to time, during the period commencing at 9:00
a.m., New York City local time, on the First Exercise Date (as hereinafter
defined), and expiring at 5:00 p.m., New York City local time, on the Last
Exercise Date (as hereinafter defined), or, if such day is a day on which
banking institutions in the City of New York are authorized by law to close,
then on the next succeeding day that shall not be such a day.

     The First Exercise Date shall be the date on which both of the following
events have occurred:

     (a)  an amendment to the Company's Certificate of Incorporation increasing
by at least 5,000,000 shares the number of shares of Common Stock of the
Company that the Company is authorized to issue is approved by the Company's
stockholders and filed in the office of the Secretary of the State of Delaware;
and

     (b)  appropriate corporate action is taken by the Company to reserve
shares of Common Stock of the Company for issuance upon the exercise of this
Warrant.

     The Last Exercise Date shall be December 31, 1997 or ninety (90) days
after the First Exercise Date, whichever shall last occur.

     Subject to the foregoing limitations, this warrant may be exercised by
presentation and surrender hereof to the Company at its principal office, or at
the office of its stock transfer agent, if any, with the Warrant Exercise Form
attached hereto duly executed and accompanied by payment (either in cash or by
certified or official bank check, payable to the order of the Company) of the
Exercise Price for the number of shares specified in such Form and instruments
of transfer, if appropriate, duly executed by the Holder or his or her duly
authorized attorney.  If this Warrant should be exercised in part only, the
Company shall, upon surrender of this Warrant for cancellation, execute and
deliver a new Warrant evidencing the rights of the Holder thereof to purchase
the balance of the shares purchasable hereunder.  Upon receipt by the Company
of this Warrant, together with the Exercise Price, at its office, or by the
stock transfer agent of the Company at its office, in proper form for exercise,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer
books of the Company shall then be closed or that certificates representing
such shares of Common Stock shall not then be actually delivered to the Holder.
The Company shall pay any and all documentary stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of shares of Common
Stock on exercise of this Warrant.

     2.   RESERVATION OF SHARES.  Until the First Exercise Date, no shares of
Common Stock will be reserved for issuance upon the exercise of this Warrant.
Thereafter, the Company will at all times reserve for issuance and delivery
upon exercise of this Warrant all shares of Common Stock or other shares of
capital stock of the Company (and other securities and property) from time to
time receivable upon exercise of this Warrant.  All such shares (and other
securities and property) shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and nonassessable and free of all
preemptive rights.

     3.   WARRANT STOCK TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.
The Warrant Stock may not be sold or otherwise disposed of except as follows:
(1) prior to registration under the Securities Act of 1933, as amended (the
"Act") to a person who, in the opinion of counsel to the Company, is a person
to whom such Warrant Stock may legally be transferred without registration and
without the





                                                                               2
<PAGE>   3
delivery of a current prospectus under the Act with respect thereto or other
disposition of such securities; or (2) upon registration, if ever, under the
Act of the Warrant Stock, to any person upon delivery of a prospectus then
meeting the requirements of the Act relating to such securities and the
offering thereof for such sale or disposition, and thereafter to all successive
assignees unless in the opinion of Counsel to the Company the delivery of such
a prospectus is not required.

     4.   FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant, but the
Company shall issue one additional share of its Common Stock in lieu of each
fraction of a share otherwise called for upon any exercise of this Warrant.

     5.   EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.  This Warrant is
not registered under the Act nor under any applicable state securities law or
regulation.  This Warrant cannot be exchanged, transferred or assigned
otherwise than by will or the laws of descent and distribution, or due to the
Holder's mental or physical incapacity and appointment of a legal guardian as a
result thereof. Upon such event and upon surrender of this Warrant to the
Company or at the office of its stock transfer agent, if any, with the
Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the heir, devisee or assignee named in such instrument
of assignment and this Warrant shall promptly be canceled.  This Warrant may be
divided or combined with other Warrants that carry the same rights upon
presentation hereof at the office of the Company or at the office of its stock
transfer agent, if any, together with written notice specifying the names and
denominations in which new Warrants are to be issued and signed by the Holder
or his executor, administrator or guardian.

     6.   RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

     7.   REDEMPTION.  This Warrant is not redeemable by the Company.

     8.   ANTI-DILUTION PROVISIONS.

          8.1  ADJUSTMENT FOR DIVIDENDS IN OTHER SECURITIES, PROPERTY, ETC.;
RECLASSIFICATION, ETC.  In case at any time or from time to time after the Base
Date the holders of Common Stock (or any other securities at the time
receivable upon the exercise of this Warrant) shall have received, or on or
after the record date fixed for the determination of eligible stockholders,
shall have become entitled to receive without payment therefor: (a) other or
additional securities or property (other than cash) by way of dividend, (b) any
cash paid or payable except out of earned surplus of the Company at the Base
Date as increased (decreased) by subsequent credits (charges) thereto (other
than credits in respect of any capital or paid-in surplus or surplus created as
a result of a revaluation of property) or (c) other or additional (or less)
securities or property (including cash) by way of stock-split, spin-off,
split-up, reclassification, combination of shares or similar corporate
rearrangement, then, and in each such case, the Holder of this Warrant, upon
the exercise thereof as provided in Section 1, shall be entitled to receive the
amount of securities and property (including cash in the cases referred to in
clauses (b) and (c) above) which such Holder would hold on the date of such
exercise if on the Base Date it had been the holder of record of the number of
shares of Common Stock (as constituted on the Base Date) subscribed for upon
such exercise as provided in Section 1 and had thereafter, during the period
from the Base Date to and including the date of such exercise, retained such
shares and/or all other additional (or less) securities and property (including
cash in the cases referred to in clauses (b) and (c) above) receivable by it as
aforesaid during such period, giving effect to all adjustments called for
during such period by Section 8.2.





                                                                               3
<PAGE>   4
          8.2  ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.  In
case of any reorganization of the Company (or any other corporation, the
securities of which are at the time receivable on the exercise of this Warrant)
after the Base Date or in case after such date the Company (or any such other
corporation) shall consolidate with or merge into another corporation or convey
all or substantially all of its assets to another corporation, then, and in
each such case, the Holder of this Warrant upon the exercise thereof as
provided in Section 1 at any time after the consummation of such
reorganization, consolidation, merger or conveyance, shall be entitled to
receive, in lieu of the securities and property receivable upon the exercise of
this Warrant prior to such consummation, the securities or property to which
such Holder would have been entitled upon such consummation if such Holder had
exercised this Warrant immediately prior thereto, all subject to further
adjustment as provided in Section 8.1; in each such case, the terms of this
Warrant shall be applicable to the securities or property receivable upon the
exercise of this Warrant after such consummation.

          8.3  CERTIFICATE AS TO ADJUSTMENTS.  In each case of an adjustment in
the number of shares of Common Stock (or other securities or property)
receivable on the exercise of the Warrant, the Company at its expense will
promptly compute such adjustment in accordance with the terms of the Warrant
and prepare a certificate setting forth such adjustment and showing in detail
the facts upon which such adjustment is based, including a statement of (a) the
consideration received or to be received by the Company for any additional
shares of Common Stock issued or sold or deemed to have been issued or sold,
(b) the number of shares of Common Stock outstanding or deemed to be
outstanding, and (c) the pro forma adjusted Exercise Price.  The Company will
forthwith mail a copy of each such certificate to each holder of the Warrant.

          8.4  NOTICES OF RECORD DATE, ETC.

               In case:

               (a) the Company shall take a record of the holders of its Common
Stock (or other securities at the time receivable upon the exercise of the
Warrant) for the purpose of entitling them to receive any dividend (other than
a cash dividend) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities,
or to receive any other right; or

               (b) of any capital reorganization of the Company (other than a
stock split or reverse stock split), any reclassification of the capital stock
of the Company, any consolidation or merger of the Company with or into another
corporation (other than a merger for purposes of change of domicile) or any
conveyance of all or substantially all of the assets of the Company to another
corporation; or

               (c) of any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, then, and in each such case, the Company shall mail
or cause to be mailed to each holder of the Warrant at the time outstanding a
notice specifying, as the case may be, (i) the date on which a record is to be
taken for the purpose of such dividend, distribution or right, and stating the
amount and character of such dividend, distribution or right, or (ii) the date
on which such reorganization, reclassification, consolidation, merger,
conveyance, dissolution, liquidation or winding-up is to take place, and the
time, if any, is to be fixed, as to which the holders of record of Common Stock
(or such other securities at the time receivable upon the exercise of the
Warrant) shall be entitled to exchange their shares of Common Stock (or such
other securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up. Such notice





                                                                               4

shall be mailed at least twenty (20) days prior to the date therein specified
and the Warrant may be exercised prior to said date during the term of the
Warrant no later than five (5) days prior to said date.

issuance of any of the shares thereunder, prior to the registration of such
shares under the Act, all certificates representing shares shall bear on the

                                                     shares of Common Stock

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK

No. BW-4-R

     FOR VALUE RECEIVED, NOISE CANCELLATION TECHNOLOGIES, INC. (the "Company"),
a Delaware corporation, hereby certifies that IRENE LEBOVICS (the "Holder") is
entitled, subject to the provisions of this Warrant (the "Warrant"), to
purchase from the Company, at any time, or from time to time, during the period
commencing at 9:00 a.m., New York City local time, on the First Exercise Date
(as hereinafter defined), and expiring, unless earlier terminated as
hereinafter provided, at 5:00 p.m., New York City local time on the Last
Exercise Date (as hereinafter defined), up to 201,250  fully paid and
nonassessable shares of Common Stock, $.01 par value, of the Company at a price
of $0.75 per share (such exercise price per share, as so adjusted, being
hereinafter referred to as the "Exercise Price") provided the Holder has
surrendered and forfeited to the Company a warrant or warrants having an
exercise price or prices of $0.75 or higher owned by Holder and entitling the
Holder to purchase 175,000 shares of Common Stock of the Company.

     The term "Common Stock" means the shares of Common Stock, $.01 par value,
of the Company as constituted on November 8, 1995, the date of grant of this
Warrant (the "Base Date"), together with any other equity securities that may
be issued by the Company in addition thereto or in substitution therefor.  The
number of shares of Common Stock to be received upon the exercise of this
Warrant may be adjusted from time to time as hereinafter set forth.  The shares
of Common Stock deliverable upon such exercise, and as adjusted from time to
time, are hereinafter sometimes referred to as "Warrant Stock".

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver a new Warrant of like tenor and date.  Any such new
Warrant executed and delivered shall constitute an additional contractual
obligation on the part of the Company, whether or not this Warrant so lost,
stolen, destroyed or mutilated shall be at any time enforceable by anyone.
<PAGE>   2
     The Holder agrees with the Company that this Warrant is issued, and all
the rights hereunder shall be held, subject to all of the conditions,
limitations and provisions set forth herein.

     1.   EXERCISE OF WARRANT.  This Warrant may be exercised in whole or in
part at any time, or from time to time, during the period commencing at 9:00
a.m., New York City local time, on the First Exercise Date (as hereinafter
defined), and expiring at 5:00 p.m., New York City local time, on the Last
Exercise Date (as hereinafter defined), or, if such day is a day on which
banking institutions in the City of New York are authorized by law to close,
then on the next succeeding day that shall not be such a day.

     The First Exercise Date shall be the date on which both of the following
events have occurred:

     (a)  an amendment to the Company's Certificate of Incorporation increasing
by at least 5,000,000 shares the number of shares of Common Stock of the
Company that the Company is authorized to issue is approved by the Company's
stockholders and filed in the office of the Secretary of the State of Delaware;
and

     (b)  appropriate corporate action is taken by the Company to reserve
shares of Common Stock of the Company for issuance upon the exercise of this
Warrant.

     The Last Exercise Date shall be December 31, 1997 or ninety (90) days
after the First Exercise Date, whichever shall last occur.

     Subject to the foregoing limitations, this warrant may be exercised by
presentation and surrender hereof to the Company at its principal office, or at
the office of its stock transfer agent, if any, with the Warrant Exercise Form
attached hereto duly executed and accompanied by payment (either in cash or by
certified or official bank check, payable to the order of the Company) of the
Exercise Price for the number of shares specified in such Form and instruments
of transfer, if appropriate, duly executed by the Holder or his or her duly
authorized attorney.  If this Warrant should be exercised in part only, the
Company shall, upon surrender of this Warrant for cancellation, execute and
deliver a new Warrant evidencing the rights of the Holder thereof to purchase
the balance of the shares purchasable hereunder.  Upon receipt by the Company
of this Warrant, together with the Exercise Price, at its office, or by the
stock transfer agent of the Company at its office, in proper form for exercise,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer
books of the Company shall then be closed or that certificates representing
such shares of Common Stock shall not then be actually delivered to the Holder.
The Company shall pay any and all documentary stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of shares of Common
Stock on exercise of this Warrant.

     2.   RESERVATION OF SHARES.  Until the First Exercise Date, no shares of
Common Stock will be reserved for issuance upon the exercise of this Warrant.
Thereafter, the Company will at all times reserve for issuance and delivery
upon exercise of this Warrant all shares of Common Stock or other shares of
capital stock of the Company (and other securities and property) from time to
time receivable upon exercise of this Warrant.  All such shares (and other
securities and property) shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and nonassessable and free of all
preemptive rights.

     3.   WARRANT STOCK TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.
The Warrant Stock may not be sold or otherwise disposed of except as follows:
(1) prior to registration under the Securities Act of 1933, as amended (the
"Act") to a person who, in the opinion of counsel to the Company, is a person
to whom such Warrant Stock may legally be transferred without registration and
without the





                                                                               2
<PAGE>   3
delivery of a current prospectus under the Act with respect thereto or other
disposition of such securities; or (2) upon registration, if ever, under the
Act of the Warrant Stock, to any person upon delivery of a prospectus then
meeting the requirements of the Act relating to such securities and the
offering thereof for such sale or disposition, and thereafter to all successive
assignees unless in the opinion of Counsel to the Company the delivery of such
a prospectus is not required.

     4.   FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant, but the
Company shall issue one additional share of its Common Stock in lieu of each
fraction of a share otherwise called for upon any exercise of this Warrant.

     5.   EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.  This Warrant is
not registered under the Act nor under any applicable state securities law or
regulation.  This Warrant cannot be exchanged, transferred or assigned
otherwise than by will or the laws of descent and distribution, or due to the
Holder's mental or physical incapacity and appointment of a legal guardian as a
result thereof. Upon such event and upon surrender of this Warrant to the
Company or at the office of its stock transfer agent, if any, with the
Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the heir, devisee or assignee named in such instrument
of assignment and this Warrant shall promptly be canceled.  This Warrant may be
divided or combined with other Warrants that carry the same rights upon
presentation hereof at the office of the Company or at the office of its stock
transfer agent, if any, together with written notice specifying the names and
denominations in which new Warrants are to be issued and signed by the Holder
or his executor, administrator or guardian.

     6.   RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

     7.   REDEMPTION.  This Warrant is not redeemable by the Company.

     8.   ANTI-DILUTION PROVISIONS.

          8.1  ADJUSTMENT FOR DIVIDENDS IN OTHER SECURITIES, PROPERTY, ETC.;
RECLASSIFICATION, ETC.  In case at any time or from time to time after the Base
Date the holders of Common Stock (or any other securities at the time
receivable upon the exercise of this Warrant) shall have received, or on or
after the record date fixed for the determination of eligible stockholders,
shall have become entitled to receive without payment therefor: (a) other or
additional securities or property (other than cash) by way of dividend, (b) any
cash paid or payable except out of earned surplus of the Company at the Base
Date as increased (decreased) by subsequent credits (charges) thereto (other
than credits in respect of any capital or paid-in surplus or surplus created as
a result of a revaluation of property) or (c) other or additional (or less)
securities or property (including cash) by way of stock-split, spin-off,
split-up, reclassification, combination of shares or similar corporate
rearrangement, then, and in each such case, the Holder of this Warrant, upon
the exercise thereof as provided in Section 1, shall be entitled to receive the
amount of securities and property (including cash in the cases referred to in
clauses (b) and (c) above) which such Holder would hold on the date of such
exercise if on the Base Date it had been the holder of record of the number of
shares of Common Stock (as constituted on the Base Date) subscribed for upon
such exercise as provided in Section 1 and had thereafter, during the period
from the Base Date to and including the date of such exercise, retained such
shares and/or all other additional (or less) securities and property (including
cash in the cases referred to in clauses (b) and (c) above) receivable by it as
aforesaid during such period, giving effect to all adjustments called for
during such period by Section 8.2.





                                                                               3
<PAGE>   4
          8.2  ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.  In
case of any reorganization of the Company (or any other corporation, the
securities of which are at the time receivable on the exercise of this Warrant)
after the Base Date or in case after such date the Company (or any such other
corporation) shall consolidate with or merge into another corporation or convey
all or substantially all of its assets to another corporation, then, and in
each such case, the Holder of this Warrant upon the exercise thereof as
provided in Section 1 at any time after the consummation of such
reorganization, consolidation, merger or conveyance, shall be entitled to
receive, in lieu of the securities and property receivable upon the exercise of
this Warrant prior to such consummation, the securities or property to which
such Holder would have been entitled upon such consummation if such Holder had
exercised this Warrant immediately prior thereto, all subject to further
adjustment as provided in Section 8.1; in each such case, the terms of this
Warrant shall be applicable to the securities or property receivable upon the
exercise of this Warrant after such consummation.

          8.3  CERTIFICATE AS TO ADJUSTMENTS.  In each case of an adjustment in
the number of shares of Common Stock (or other securities or property)
receivable on the exercise of the Warrant, the Company at its expense will
promptly compute such adjustment in accordance with the terms of the Warrant
and prepare a certificate setting forth such adjustment and showing in detail
the facts upon which such adjustment is based, including a statement of (a) the
consideration received or to be received by the Company for any additional
shares of Common Stock issued or sold or deemed to have been issued or sold,
(b) the number of shares of Common Stock outstanding or deemed to be
outstanding, and (c) the pro forma adjusted Exercise Price.  The Company will
forthwith mail a copy of each such certificate to each holder of the Warrant.

          8.4  NOTICES OF RECORD DATE, ETC.

               In case:

               (a) the Company shall take a record of the holders of its Common
Stock (or other securities at the time receivable upon the exercise of the
Warrant) for the purpose of entitling them to receive any dividend (other than
a cash dividend) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities,
or to receive any other right; or

               (b) of any capital reorganization of the Company (other than a
stock split or reverse stock split), any reclassification of the capital stock
of the Company, any consolidation or merger of the Company with or into another
corporation (other than a merger for purposes of change of domicile) or any
conveyance of all or substantially all of the assets of the Company to another
corporation; or

               (c) of any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, then, and in each such case, the Company shall mail
or cause to be mailed to each holder of the Warrant at the time outstanding a
notice specifying, as the case may be, (i) the date on which a record is to be
taken for the purpose of such dividend, distribution or right, and stating the
amount and character of such dividend, distribution or right, or (ii) the date
on which such reorganization, reclassification, consolidation, merger,
conveyance, dissolution, liquidation or winding-up is to take place, and the
time, if any, is to be fixed, as to which the holders of record of Common Stock
(or such other securities at the time receivable upon the exercise of the
Warrant) shall be entitled to exchange their shares of Common Stock (or such
other securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up. Such notice





                                                                               4

issuance of any of the shares thereunder, prior to the registration of such

deliver a new Warrant evidencing the rights of the Holder thereof to purchase
the balance of the shares purchasable hereunder.  Upon receipt by the Company
of this Warrant, together with the Exercise Price, at its office, or by the
stock transfer agent of the Company at its office, in proper form for exercise,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer
books of the Company shall then be closed or that certificates representing
such shares of Common Stock shall not then be actually delivered to the Holder.
The Company shall pay any and all documentary stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of shares of Common
Stock on exercise of this Warrant.

     2.   RESERVATION OF SHARES.  Until the First Exercise Date, no shares of
Common Stock will be reserved for issuance upon the exercise of this Warrant.
Thereafter, the Company will at all times reserve for issuance and delivery
upon exercise of this Warrant all shares of Common Stock or other shares of
capital stock of the Company (and other securities and property) from time to
time receivable upon exercise of this Warrant.  All such shares (and other
securities and property) shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and nonassessable and free of all
preemptive rights.

     3.   WARRANT STOCK TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.
The Warrant Stock may not be sold or otherwise disposed of except as follows:
(1) prior to registration under the Securities Act of 1933, as amended (the
"Act") to a person who, in the opinion of counsel to the Company, is a person
to whom such Warrant Stock may legally be transferred without registration and
without the





                                                                               2
<PAGE>   3
delivery of a current prospectus under the Act with respect thereto or other
disposition of such securities; or (2) upon registration, if ever, under the
Act of the Warrant Stock, to any person upon delivery of a prospectus then
meeting the requirements of the Act relating to such securities and the
offering thereof for such sale or disposition, and thereafter to all successive
assignees unless in the opinion of Counsel to the Company the delivery of such
a prospectus is not required.

     4.   FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant, but the
Company shall issue one additional share of its Common Stock in lieu of each
fraction of a share otherwise called for upon any exercise of this Warrant.

     5.   EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.  This Warrant is
not registered under the Act nor under any applicable state securities law or
regulation.  This Warrant cannot be exchanged, transferred or assigned
otherwise than by will or the laws of descent and distribution, or due to the
Holder's mental or physical incapacity and appointment of a legal guardian as a
result thereof. Upon such event and upon surrender of this Warrant to the
Company or at the office of its stock transfer agent, if any, with the
Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the heir, devisee or assignee named in such instrument
of assignment and this Warrant shall promptly be canceled.  This Warrant may be
divided or combined with other Warrants that carry the same rights upon
presentation hereof at the office of the Company or at the office of its stock
transfer agent, if any, together with written notice specifying the names and
denominations in which new Warrants are to be issued and signed by the Holder
or his executor, administrator or guardian.

     6.   RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

     7.   REDEMPTION.  This Warrant is not redeemable by the Company.

     8.   ANTI-DILUTION PROVISIONS.

          8.1  ADJUSTMENT FOR DIVIDENDS IN OTHER SECURITIES, PROPERTY, ETC.;
RECLASSIFICATION, ETC.  In case at any time or from time to time after the Base
Date the holders of Common Stock (or any other securities at the time
receivable upon the exercise of this Warrant) shall have received, or on or
after the record date fixed for the determination of eligible stockholders,
shall have become entitled to receive without payment therefor: (a) other or
additional securities or property (other than cash) by way of dividend, (b) any
cash paid or payable except out of earned surplus of the Company at the Base
Date as increased (decreased) by subsequent credits (charges) thereto (other
than credits in respect of any capital or paid-in surplus or surplus created as
a result of a revaluation of property) or (c) other or additional (or less)
securities or property (including cash) by way of stock-split, spin-off,
split-up, reclassification, combination of shares or similar corporate
rearrangement, then, and in each such case, the Holder of this Warrant, upon
the exercise thereof as provided in Section 1, shall be entitled to receive the
amount of securities and property (including cash in the cases referred to in
clauses (b) and (c) above) which such Holder would hold on the date of such
exercise if on the Base Date it had been the holder of record of the number of
shares of Common Stock (as constituted on the Base Date) subscribed for upon
such exercise as provided in Section 1 and had thereafter, during the period
from the Base Date to and including the date of such exercise, retained such
shares and/or all other additional (or less) securities and property (including
cash in the cases referred to in clauses (b) and (c) above) receivable by it as
aforesaid during such period, giving effect to all adjustments called for
during such period by Section 8.2.





                                                                               3
<PAGE>   4
          8.2  ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.  In
case of any reorganization of the Company (or any other corporation, the
securities of which are at the time receivable on the exercise of this Warrant)
after the Base Date or in case after such date the Company (or any such other
corporation) shall consolidate with or merge into another corporation or convey
all or substantially all of its assets to another corporation, then, and in
each such case, the Holder of this Warrant upon the exercise thereof as
provided in Section 1 at any time after the consummation of such
reorganization, consolidation, merger or conveyance, shall be entitled to
receive, in lieu of the securities and property receivable upon the exercise of
this Warrant prior to such consummation, the securities or property to which
such Holder would have been entitled upon such consummation if such Holder had
exercised this Warrant immediately prior thereto, all subject to further
adjustment as provided in Section 8.1; in each such case, the terms of this
Warrant shall be applicable to the securities or property receivable upon the
exercise of this Warrant after such consummation.

          8.3  CERTIFICATE AS TO ADJUSTMENTS.  In each case of an adjustment in
the number of shares of Common Stock (or other securities or property)
receivable on the exercise of the Warrant, the Company at its expense will
promptly compute such adjustment in accordance with the terms of the Warrant
and prepare a certificate setting forth such adjustment and showing in detail
the facts upon which such adjustment is based, including a statement of (a) the
consideration received or to be received by the Company for any additional
shares of Common Stock issued or sold or deemed to have been issued or sold,
(b) the number of shares of Common Stock outstanding or deemed to be
outstanding, and (c) the pro forma adjusted Exercise Price.  The Company will
forthwith mail a copy of each such certificate to each holder of the Warrant.

          8.4  NOTICES OF RECORD DATE, ETC.

               In case:

               (a) the Company shall take a record of the holders of its Common
Stock (or other securities at the time receivable upon the exercise of the
Warrant) for the purpose of entitling them to receive any dividend (other than
a cash dividend) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities,
or to receive any other right; or

               (b) of any capital reorganization of the Company (other than a
stock split or reverse stock split), any reclassification of the capital stock
of the Company, any consolidation or merger of the Company with or into another
corporation (other than a merger for purposes of change of domicile) or any
conveyance of all or substantially all of the assets of the Company to another
corporation; or

               (c) of any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, then, and in each such case, the Company shall mail
or cause to be mailed to each holder of the Warrant at the time outstanding a
notice specifying, as the case may be, (i) the date on which a record is to be
taken for the purpose of such dividend, distribution or right, and stating the
amount and character of such dividend, distribution or right, or (ii) the date
on which such reorganization, reclassification, consolidation, merger,
conveyance, dissolution, liquidation or winding-up is to take place, and the
time, if any, is to be fixed, as to which the holders of record of Common Stock
(or such other securities at the time receivable upon the exercise of the
Warrant) shall be entitled to exchange their shares of Common Stock (or such
other securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up. Such notice





                                                                               4

shall be mailed at least twenty (20) days prior to the date therein specified
and the Warrant may be exercised prior to said date during the term of the
Warrant no later than five (5) days prior to said date.

     9.   LEGEND.  In the event of the exercise of any of the Warrants and the
issuance of any of the shares thereunder, prior to the registration of such
shares under the Act, all certificates representing shares shall bear on the
face thereof substantially the following legends, insofar as is consistent with
Delaware law:

representations set forth in Section 6.12 above.

                         ARTICLE IX -- OTHER COVENANTS

acknowledge and agree that except to the extent otherwise expressly provided in
the License Agreements, WEM shall have the right to enter into any partnership,
joint venture or other arrangement or enterprise for purposes of using,
exploiting or further developing any or all of the Assets.  Without limiting

any intellectual property or other developments of the third party in

corresponding rights and obligations, if any, provided pursuant to the license
agreement which constitutes a part of the Original Agreements shall apply, with
WEM as a permitted successor to WNCT, and for such purpose shall thereafter
remain in effect perpetually except to the extent that the same would terminate
as provided in the corresponding license agreement which constitutes a part of
the Restructuring Agreements, and such license agreements are hereby amended in
all respects necessary to give effect to the provisions of this Section 9.02
and no further action shall required by any party thereto to effect such
amendments.

Agreement to be consummated at the Closing shall be borne and paid solely by
the NCT Parties, which shall be jointly and severally liable therefor, and paid
at the Closing and any such amounts not paid prior to or at the Closing may, at
WEM's option, be withheld by WEM from the Cash Payment and paid directly by WEM
to the taxing authority in question.  Provided that WEM is furnished with
appropriate tax exemption certificates and evidence satisfactory to WEM that
the NCT Parties have satisfied or otherwise complied with all requirements
under any applicable law with respect to any claimed exemption, WEM shall not
deduct or withhold any such Transfer Taxes from the Cash Payment to the extent
such exemption is satisfied.

              9.04  Liability for Taxes.  Without affecting liabilities for
which WEM is already responsible by virtue of its position as an existing
general partner in WNCT and without limiting the generality of Section 2.03
above, WEM is not assuming any liability for any Taxes imposed on or in
connection with the Assets for taxable periods or portions thereof ending on or
before the Closing Date.  The apportionment of liabilities for Taxes for

property Taxes, payments in lieu of such Taxes, and similar Taxes or fees which
shall be apportioned between the NCT Parties and WEM on a pro-rata daily basis
over the relevant tax period, based on the tax period or portions thereof for
which each is responsible (with the day immediately following the Closing Date
being the first day WEM owns the Assets for purposes of this Section 9.05).
Notwithstanding anything provided herein to the contrary, the NCT Parties shall
be responsible for all income Taxes incurred, arising from or imposed as a
result of the sale and transfer of the Assets pursuant to this Agreement. The
amount of (if any) property Taxes, payments in lieu of such Taxes or similar





                                      -17-
<PAGE>   23

the NCT Parties shall be credited against the Cash Payment payable by WEM at
the Closing.

constituting consideration paid by WEM or received by any of the NCT Parties in
connection with the transactions to be consummated at the Closing shall be
allocated among the Assets and other acquired rights as set forth in SCHEDULE
9.05 attached hereto.  Each of the NCT Parties (on the one hand) and WEM (on
the other hand) shall file any reports required to be filed under applicable
laws or regulations, including without limitation I.R.S. Form 8594, consistent
with such allocation.

              9.06  Bulk Transfer Law Requirements.  Each of the parties
hereto hereby waives compliance by all parties hereto with the requirements of
any applicable Bulk Transfer Laws; provided, that such waiver shall not
constitute a waiver of, or affect the generality of or limit the effect of any
of, the provisions of any of the Restructuring Agreements (including without
limitation the indemnification obligations set forth in Section 7.01 of the
Support, Research and Development Agreement).

                        CPH TECHNOLOGY LICENSE AGREEMENT


                 This License Agreement ("Agreement") is made and entered into
this 15th day of November, 1995 by and between Chaplin Patents Holding Co.,
Inc., a Delaware corporation ("CPH"), and Walker Electronic Mufflers, Inc., a
Delaware corporation ("WEM").

                                  INTRODUCTION

                 CPH is the owner of certain patents and technology relating to
the reduction and elimination of noise and vibration (as more particularly
described below in Section 1.01.07 of this Agreement and defined as the "CPH
Technology"), including without limitation the patents identified in SCHEDULE
1.01.06 attached hereto (which patents are more particularly described below in
Section 1.01.06 and defined as the "CPH Patents").  CPH and Noise Cancellation
Technologies, Inc. ""NCT") entered into a license agreement dated June 21,
1989, pursuant to which CPH granted to NCT a license of the CPH Technology.
NCT, WEM, Walker Manufacturing Company, a division of Tennessee Gas Pipeline
Company, and NCT Muffler, Inc. entered into a joint venture and partnership
agreement dated November 8, 1989 which formed a New York general partnership
known as Walker Noise Cancellation Technologies ("WNCT").  NCT and WNCT entered
into a license agreement dated as of November 8, 1989 (as amended, the "WNCT
License") pursuant to which NCT granted to WNCT a sublicense of the CPH
Technology.  NCT, WEM, Walker Manufacturing Company, a division of Tennessee
Gas Pipeline Company, NCT Muffler, Inc., CPH and WNCT entered into a Transfer
Agreement of even date which restructures rights and obligations with respect
to WNCT and, among other things, the aforementioned WNCT License.  This license

                              TERMS AND CONDITIONS

                 In consideration of the foregoing, the mutual covenants set
forth herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree
as follows:

                            ARTICLE I:  DEFINITIONS

                 1.01     Defined Terms.  As used herein, the following
         terms have the following meanings:

                 1.01.01  Affiliate.  The term "Affiliate" shall mean,
         with respect to any person or entity, any other person or entity that
         directly, or indirectly through one or more intermediaries, controls,
         is controlled by, or is under common control with the person or entity
         specified, together with their respective officers, directors and





                                      -1-
<PAGE>   5
         shareholders.  For purposes of this Section 1.01.01, "control" of an
         entity shall be deemed to exist by virtue of having the right to
         influence the operation and affairs thereof by holding directly or
         indirectly 50% or more of the equity interests in such entity.

                 1.01.02  ANVT Licenses.   The term "ANVT Licenses" (and singly
         an "ANVT License") shall mean the license agreements more particularly
         described on the attached SCHEDULE 1.01.02.

                 1.01.03  ANVT Technology.  The term "ANVT Technology" shall
         mean such of the following as to which CPH or any of its Affiliates
         have any rights: any and all existing and future technology related to
         the control, attenuation and/or cancellation of noise and/or
         vibration, now, hereafter or previously owned by or licensed to ANVT
         or any of its Affiliates (other than any of the CPH Patents and
         technology owned by CPH), including without limitation all know-how,
         trade secrets, methods, operating techniques, processes, software,
         materials, technical data, engineering information, drawings,
         machinery and apparatus, patents (including without limitation the
         patents identified on the attached SCHEDULE 1.01.03 and any
         continuations, continuations-in-part, divisions or reissues thereof
         and any patents covering any Improvements thereto), patent
         applications, copyrights and other intellectual property relating
         thereto; provided, that any Improvements made by any Person other than
         the licensee of an ANVT License or ANVT itself which are applicable to
         the ANVT Technology shall not constitute part of the ANVT Technology.

                 1.01.04  Controller or Chip.  The terms "Controller"
         or "Chip" as used herein with respect to the electronic products which
         attenuate noise and/or vibrations shall mean the component which
         receives input concerning noise and vibration levels and in turn
         directly or indirectly adjusts either or both (i) the frequency and/or
         amplitude of countervailing soundwaves or vibrations and/or (ii) the
         air pressure used to interfere with the noise or vibration (or both).
         To the extent that such component consists of multiple chips which
         function together rather than independently to effect any of the
         aforementioned adjustments, all elements of such component, including
         such chips, taken together shall be deemed for purposes of this
         Agreement to constitute a single Controller or Chip.

                 1.01.05  CPH Marks.  "CPH Marks" shall have the meaning
         ascribed to it in Section 6.01 below.

                 1.01.06  CPH Patents.  "CPH Patents" shall mean the patents
         owned by CPH and listed in SCHEDULE 1.01.06 attached hereto, and any
         continuations, continuations-in-    





                                      -2-

                 3.04     Sales or Leases by CPH.  Without affecting
the effect or generality of Section 2.03 above, CPH shall pay royalties to WEM
with respect to the sale or lease by CPH of (i) Vehicular Quieting Single
Application Products, or (ii) any product which incorporates any Improvement
which is subject to the license to CPH described in Section 2.08 above.  The
amount of the royalties payable under this Section 3.04 shall be calculated as
a percentage, as set forth below with respect to each of the aforementioned
categories of products, of the Net Revenues (as hereinafter defined) received
by WEM in connection with the sale or lease of such products:

                 (a)      Vehicular Quieting Single
                          Application Products                 --      **

                 (b)      Products which incorporate any
                          Improvement which is subject to
                          the license to CPH described in
                          Section 2.08 above:                  --      **

                 3.05     Licensing and Sublicensing by CPH.  Without
affecting the effect or generality of Section 2.03 above, CPH shall pay a
royalty to WEM with respect to licenses or sublicenses, as the case may be,
granted at any time by CPH or as to which CPH is now or hereafter becomes the
owner or holder of the licensor's or sublicensor's rights, for sales or leases
of (i) Vehicular Quieting Single Application Products, or (ii) any product
which incorporates any Improvement which is subject to the license to CPH
described in Section 2.08 above, and CPH shall also pay a royalty to WEM with
respect to any of the licenses described in Sections 2.04(b), 2.04(c) or
2.04(d) above as to which CPH becomes the owner or holder of any of the
licensor's or sublicensor's rights thereunder.  The amount of the royalties
payable under this Section 3.05 shall, with respect to each license or
sublicense in question, constitute the larger of the two amounts determined
pursuant to subparts (a) and (b) of this Section 3.05.

                 (a)      For purposes of this Section 3.05, the amount
                          determined in this subpart (a) shall constitute one
                          of the following three amounts, as selected by CPH:

2.04(b) (ii) through (v), 2.04(c) and 2.04(d) above, CPH shall pay a royalty to
WEM on the same basis as is provided with respect to the licenses and
sublicenses which are described in Section 3.05 above; provided, that with
respect to the licenses referred to in Section 2.04(b), such royalty obligation
shall not apply with respect to either (i) the sale or lease of any products
thereunder prior to the date of the assignment by ANVT to NCT of the licensor's
(or sublicensor's) rights thereunder, or (ii) that period of time for which
complete royalties were paid thereunder prior to the aforementioned assignment
by ANVT to NCT of the licensor's (or sublicensor's) rights thereunder and for
which no payment was actually received by CPH.  Royalties payable by CPH to WEM
pursuant to Section 3.05 above shall be credited to the royalties payable under
this Section 3.06 to the extent (but only to the extent) that the Net Revenues
or other amounts referred to in this Section 3.06 are attributable to the sale
or lease of a product, or the grant of a license or sublicense, for which a
royalty is payable by CPH to WEM pursuant to Section 3.05 above.

                 3.07     Accrual of Royalty Obligations.  The
obligation to pay a royalty due under this Agreement in connection with the
sale of a product shall arise upon consummation of the sale in question.  The
obligation to pay a royalty due under this Agreement in connection with a
lease, sublicense or license to a third party shall arise upon the receipt by
the royalty obligor of the payment to it under such lease, license or
sublicense agreement to which the royalty relates.

                 3.08     Royalty Payment Dates.  The royalties
described in this Article III shall be paid in arrears on a quarterly basis,
and all royalty payments shall be accompanied by a statement showing the costs
incurred or Net Revenues received, as applicable, and a calculation of the
royalties due for the applicable calendar quarter.  Royalty payments shall be
due not later than the thirtieth (30th) day following the end of each calendar
quarter from and after the date of this Agreement.

                 3.09     Books and Records.  WEM and CPH shall have
the right to inspect and audit the relevant books and records of the other, and
each shall cause its Affiliates to also permit the relevant books and records
of each Affiliate to be inspected and audited, upon reasonable advance notice
and during normal business hours for the sole purpose of verifying amounts of
royalties due pursuant to this Agreement; provided, that each party shall have
the right to conduct any such audit and inspection not more often than two
times during each calendar year.  The cost of any such audit shall be borne by
the requesting party unless the audit reveals an underpayment of two percent or
more with respect to any specific royalty or with respect to the aggregate
amount of all types of royalties payable by such party for any calendar quarter
or for one year in total, in which case the cost of the audit shall be borne by
the audited party.

                 3.10     Interest.  Any amounts for royalties not paid
when due shall bear interest for each day on which any such amounts remain due
and unpaid at the lesser of (i) an annual rate of four percentage points in
excess of the interest rate identified as the prime rate of interest in the
Wall Street Journal, or (ii) the maximum interest rate permitted by applicable
law.

                 3.11     Royalty Exceptions.  Notwithstanding anything
provided herein to the contrary, a party obligated to pay royalties to the
other party to this Agreement shall not be obligated to pay such royalties to
such other party for, or during, any period during which such other party or an
Affiliate of such other party is in material breach of any provision of the
Transfer Agreement or any other of the Restructuring Agreements.  In addition,
no royalties shall be due with respect to any product which, or any license or
any sublicense pursuant to which a product is manufactured, sold, leased or
used if the product in question is one which, incorporates or is based only
upon (i) technology covered by the claim of a patent which has expired, (ii)
any portion of the CPH Technology, with the exception of issued patents, which
does not continue to constitute confidential and proprietary information of CPH
as to which the exclusive rights granted hereunder can be enforced, or (iii)
both; provided, that the foregoing provisions of this sentence shall not apply
with respect to, and during the period that WEM continues to receive revenues
pursuant to, licenses or sublicenses granted by WEM prior to the expiration of
the patent or patents in question or prior to the time that the enforceability
of the exclusive rights granted hereunder became unenforceable with respect to
the portion of the CPH Technology in question.  Notwithstanding anything else
contained herein, royalties otherwise due hereunder shall not be payable to the
extent expressly provided in the Support, Research and Development Agreement
constituting one of the Restructuring Agreements and, further, WEM shall not be
obligated to pay any royalties to CPH with respect to (i) the manufacture, use,
sale or lease of any products or systems incorporating CPH Technology, or (ii)
licenses or sublicenses which include rights to the CPH Technology, in either
case for which WEM is obligated to pay and has actually paid royalties to NCT
under the license agreement of even date herewith between NCT (as the licensor)
and WEM (the "NCT License Agreement").  Notwithstanding anything else contained
herein, CPH shall not be obligated to pay any royalties to WEM with respect to
(i) the manufacture, use, sale or lease of any products or systems
incorporating CPH Technology, or (ii) licenses or sublicenses which include
rights to the CPH Technology, in either case for which NCT is obligated to pay
and has actually paid royalties to WEM under the NCT License Agreement.

set forth, explain or otherwise relate to that part of the CPH Technology
identified in SCHEDULE 4.01(b), and CPH shall deliver to WEM, from time to time
upon request, all such items with respect to any other part of the CPH
Technology.  Without limiting the generality of the foregoing, CPH shall
furnish to WEM at the Closing copies of all source codes for all software
included within the CPH Technology identified in SCHEDULES 4.01(a) AND 4.01(b).

                 4.02     Delivery of Improvements.  Contemporaneously
with the delivery of the royalty calculation reports described in Section 3.08,
above, each party hereto shall furnish a written report to the other describing
in reasonable detail all Improvements to the CPH Technology made or caused to
be made by such party or any of its Affiliates during the immediately preceding
calendar quarter or, if none, reciting that no such Improvements have been made
or acquired by such party or its Affiliates during such quarter.  With respect
to all Improvements disclosed in each such report, the party submitting the
report shall also deliver to the recipient of the report, as soon as is
reasonably practicable following a written request, copies of all documents and
materials (whether written or in machine-readable format on magnetic or other
media) and things which contain, set forth, explain or otherwise relate to the
intellectual property comprising each of the Improvements in question
(including without limitation copies of source codes).

                          ARTICLE V:  OTHER COVENANTS

                 5.01     Restrictions Concerning Exclusive Field.  CPH
shall not, and shall not permit its Affiliates or any third parties to, grant
any licenses or sublicenses of the CPH Technology for use in the Exclusive
Field to any third party subsequent to the date of this Agreement.  In
addition, with the exception of amendments to economic terms and conditions for
the limited purpose of increasing royalty rates and with the additional
exception of the affirming license agreement between NCT and Arvin Industries,
Inc. more particularly described in SCHEDULE 5.05(b), CPH shall not, and shall
not permit any of its Affiliates or any third party to, amend or alter any of
the ANVT Licenses or any other pre-existing licenses or sublicenses of the CPH
Technology that involve rights within or pertaining to the Exclusive Field.

                 5.02     Notice of Licenses.  CPH shall itself, and
shall cause its Affiliates to, notify WEM in writing at least twenty (20)
business days in advance of granting to any third party any subsequent licenses
or sublicenses of any type with respect to any of the CPH Technology.  Such
written notice shall include or be accompanied by a certificate of an officer
of CPH, or other evidence reasonably satisfactory to WEM, reflecting that, and
CPH hereby covenants that, the proposed license or sublicense (i) will not
infringe upon WEM's exclusive rights in the Exclusive Field, (ii) will either
include a grant-back provision to the licensor that will permit WEM and its





                                      -21-
<PAGE>   25
Affiliates to use, as a part of the license granted hereunder, all Improvements
made by the licensee or, if such a grant-back provision is not included, that
such proposed license or sublicense will not include any rights to any of the
Improvements described in Section 2.08 above, and (iii) to the extent that any
grant-back provisions will be included in such proposed license or sublicense,
will include provisions of the type described in Section 5.03 below.  CPH shall
use its reasonable best efforts to cause any subsequent license or sublicense
(or permitted amendment of any existing license or sublicense) to include a
grant-back provision to the licensor that will permit WEM and its Affiliates to
use, as a part of the license granted hereunder, all Improvements made by the
licensee.

                 5.03     Third Party Beneficiary.  CPH shall cause any
subsequent license or sublicense of the CPH Technology to include a provision
expressly designating WEM as a third party beneficiary of the obligations of
the licensor and licensee under such license to ensure WEM's access to
Improvements and its ability to enforce the provisions of Sections 5.01 and
5.02, above.

                 5.04     Maintenance and Enforcement.  CPH shall pay
or cause to be paid when due all maintenance fees and annuities for each of the
patents covering any of the CPH Technology, and shall furnish to WEM, not less
often than quarterly, a report reflecting in reasonable detail the status of
such maintenance fees and annuities payments.  CPH also shall take all action
reasonably required to enforce the patents covering the CPH Technology against
infringement by third parties or other challenge (including without limitation
claims of invalidity or unenforceability), and shall promptly furnish WEM with
written notice of any actual or threatened action or proceeding concerning the
same.  In addition, CPH shall furnish to WEM, upon request from time to time,
written reports describing in reasonable detail the status of any such matters.
In the event that CPH is unable or otherwise does not intend to (i) pay any
such patent maintenance fees or annuities, or (ii) take any action concerning
any such infringement or other challenge, CPH shall promptly notify WEM to that
effect, which notice shall in any event be given not later than the last day of
such period of time as would allow WEM sufficient time to make any such payment
or take action concerning any such infringement or other challenge prior to the
expiration of any rights to do so.  If CPH fails to (i) pay any such patent
maintenance fees or annuities, or (ii) take any action concerning any such
infringement or other challenge, WEM shall have the right, but not the
obligation, to make such payment or to take such action, in its own name or (in
WEM's discretion) in the name and on behalf of CPH, as it deems appropriate to
defend the CPH Technology from such infringement or other challenge, and CPH
shall take all such action, at its own expense, as may be reasonably requested
by WEM to cooperate with such action by WEM.

and represents to WEM as follows:  (i) CPH is the owner of the CPH Patents,
free and clear of any liens, encumbrances or claims (but subject to the
licenses identified in SCHEDULE 5.05(A), none of which contain any provisions

granted hereunder or of CPH's right to grant the rights hereunder), and except
as otherwise expressly set out in SCHEDULE 5.05(A) hereto, is the owner of the
CPH Technology or possesses nonterminable (except to the extent that any
patents covering such technology are adjudicated to be invalid or
unenforceable, and CPH hereby represents and warrants that it has no knowledge
of any pending or threatened proceedings, or any basis therefor, which could
have such result), perpetual worldwide license rights thereto which include the
right to grant the license thereto pursuant to this Agreement, in each case
free and clear of any liens, encumbrances or claims; (ii) SCHEDULE 5.05(b)
hereto contains a complete description of each of the rights of third parties
to ANVT Technology with respect to the fields of application referred to in
Section 2.02 above as to which such Section 2.02 recites that WEM is not
granted a license hereunder to use ANVT Technology; (iii) SCHEDULE 5.05(b)
hereto contains a complete description of each of the rights of the third
parties referred to in Section 2.04 as constituting exceptions to the otherwise
exclusive rights of WEM granted pursuant to this Agreement and no other rights
have been granted by any of the NCT Parties or, to the Knowledge of the NCT
Parties, upon due inquiry by or on behalf of CPH, by ANVT which could infringe
upon such exclusivity; and (iv) no representation or warranty made herein by
CPH, and no schedule attached hereto, contains any untrue statement of a
material fact or omits to state a material fact or to include any information
necessary to make such representation, warranty or schedule not misleading or
incomplete in light of the circumstances under which it is made or prepared, as
the case may be.

             ARTICLE VI:  TRADEMARKS, SERVICE MARKS AND TRADE NAMES

                 6.01     CPH Marks.  CPH hereby grants to WEM a
non-exclusive license to use the Names and Marks CHAPLIN PATENTS, CHAPLIN, and
CPH (the "CPH Marks") in connection with its business and products which
incorporate the CPH Technology.  CPH hereby agrees that it shall not oppose or
object to WEM's use of the CPH Marks.  In addition, CPH shall cause such of its
Affiliates as may be designated by WEM from time to time to execute, either
contemporaneously with CPH's execution of this Agreement or thereafter, an
acknowledgment in form reasonably satisfactory to WEM confirming the rights of
WEM under this Section 6.01 and Section 6.02 below.

                 6.02     WNCT Marks.  CPH hereby acknowledges and
agrees that pursuant to the NCT License Agreement, WEM shall have the right to
use the names and marks of WALKER NOISE CANCELLATION TECHNOLOGIES, WNCT, WALKER
ELECTRONIC SILENCERS, WALKER ELECTRONIC SILENCING and WALKER INDUSTRIAL
SILENCERS (the "WNCT Marks") in connection with its business and products which





                                      -23-
<PAGE>   27
incorporate technology licensed to WEM under such other license agreement.  CPH
hereby agrees that it shall not oppose or object to WEM's use or registration
of the WNCT Marks.

                         ARTICLE VII:  CONFIDENTIALITY
                          
                 7.01     Confidentiality Covenants.  Except as expressly
otherwise provided herein, each of the parties agrees that it shall not
disclose, nor shall it induce or permit others to disclose, to any third party
any of the terms and conditions of this Agreement or information learned in
course of inspecting the books and records of the other party or pertaining to
any intellectual property or other technology licensed to it by the other party
hereto; provided, that such information may be disclosed to the extent necessary
to give effect to any license or sublicense contemplated or otherwise permitted
by this Agreement.  Each party shall, prior to disclosing any such information
in accordance with this Section 7.01, cause each person or entity given access
to such information to enter into a binding and enforceable agreement pursuant
to which the recipient of such information agrees to be bound by the covenants
of this Article VII for the benefit of the licensor (or sublicensor, as the case
may be) and for the benefit of WEM or CPH (whichever is not the licensor or
sublicensor in question, as the case may be). Notwithstanding anything provided
herein to the contrary, the covenants restricting disclosure set forth in this
Section 7.01 shall not apply with respect to information or other items that the
recipient thereof can show (i) was known or becomes known to the general public
without disclosure by such recipient (or any Affiliate of such recipient), (ii)
was already known by the recipient thereof before its disclosure by a party
hereto, or (iii) was legally acquired by the recipient thereof from another
party and in good faith, provided that such disclosure by the other party was
not a breach of any agreement or in derogation of any confidential relationship
between such other party and any other party hereto.  In addition, and
notwithstanding the foregoing, if legal counsel for either CPH, WEM or any of
their respective Affiliates is of the opinion that a statement, announcement or
filing involving the disclosure of any of the terms or conditions hereof is
required by law or regulation or by the rules of any stock exchange on which its
securities are traded, then such entity may issue a statement or announcement or
make a filing, in each instance limited solely to that which legal counsel for
such party advises is required under law or such rules.  A party as to which any
such statement, announcement or filing is proposed on its own behalf or on
behalf of an Affiliate thereof shall provide a copy thereof to the other party
for its prior review, and shall use its reasonable best efforts to cause any
such filing to be accomplished on a basis that includes the redaction of all
economic terms and conditions (including without limitation the amounts of
royalties) and any other terms and conditions as to which redaction is
reasonably requested by such other party, and shall cooperate with and permit
such other party to participate in the process of seeking such redaction.

                         ARTICLE VIII:  INDEMNIFICATION

                 8.01     Indemnification by CPH.  CPH hereby agrees to
indemnify and to hold WEM and its Affiliates, and the officers, directors,
shareholders, agents and employees of each of them (collectively the "WEM
Indemnitees" and singly a "WEM Indemnitee") harmless from and against any and
all liability, loss, damage or injury, together with all reasonable costs and
expenses relating thereto (including but not limited to legal and accounting
fees) arising out of or resulting from any claim which is asserted against any
of the WEM Indemnitees which includes any allegation of any product liability
claim concerning design based upon any defective design of the CPH Technology
(except with respect to but only to the extent of, allegations of defective
design pertaining only to Improvements made by or on behalf of WEM other than
those made on behalf of WEM by CPH).

                 8.02     Indemnification by WEM.  WEM hereby agrees to
indemnify and hold CPH, its Affiliates, and the shareholders, directors,
officers, employees and agents of each of them (collectively the "CPH
Indemnitees" and singly a "CPH Indemnitee") harmless from and against any and
all liability, loss, damage or injury, together with all reasonable costs and
expenses relating thereto (including but not limited to legal and accounting
fees) arising out of or resulting from any claim which is asserted against an
CPH Indemnitee involving any allegation of any products liability in connection
with a product manufactured by or on behalf of WEM or any of its Affiliates
which incorporated any of the CPH Technology; provided that with respect to any
such product which incorporates any of the CPH Technology, the obligation to
provide indemnification under this Section 8.02 shall not apply to the extent
such claim includes or is asserted in connection with any allegation of
defective design in the CPH Technology (except with respect to but only to the
extent of, allegations of defective design pertaining only to Improvements made
by or on behalf of WEM other than those made on behalf of WEM by CPH).

                 8.03     Control of Contest.  For purposes of this
Section 8, the party entitled to indemnification is referred to as the
"Indemnitee" and the party obligated to provide indemnification is referred to
as the "Indemnitor."  The Indemnitor shall have the right, at its own expense,
to control any claim or matter as to which such Indemnitor is obligated to
provide indemnification pursuant to any provision of this Agreement.  This
shall include the right to designate the attorneys and other professionals who
shall defend or pursue any such claim or matter and to make the decision
whether to pursue any such claim or matter to a judgment, to settle any such
claim or matter, or to agree to any such claim or matter without any contest
thereof; provided, that (i) the Indemnitor shall obtain the prior approval of
the Indemnitee(s) to legal counsel engaged to defend or pursue any such claim
or matter, which approval shall not be unreasonably withheld, and (ii) no
Indemnitor shall have the right to agree to settle any claim or matter in a
manner that would adversely affect the interest of any





                                      -25-
<PAGE>   29
Indemnitee without the written consent of the adversely affected Indemnitee or
Indemnitees, as the case may be, which consent shall not be unreasonably
withheld.  From and after the date on which the Indemnitor assumes control of
the defense of any manner as to which indemnification is required hereunder,
the Indemnitor shall not be obligated to pay any attorneys' fees incurred by
the Indemnitee(s) for additional counsel retained directly by the Indemnitee(s)
without the consent of the Indemnitor; provided, that in the event that any
Indemnitor is unable or unwilling to satisfy its indemnification obligation
hereunder, the Indemnitee(s) shall be entitled to engage at that Indemnitor's
expense the attorneys and other professionals who shall defend or pursue such
claim or matter and shall also be entitled to make any decision whether to
defend, pursue or settle such claim or matter.

                 8.04     Notice and Cooperation.  The Indemnitee shall promptly
notify the Indemnitor upon learning of any claim or matter as to which
indemnification is required pursuant to this Section 8; provided, that the
failure to provide any such notice to an Indemnitor shall not relieve that
Indemnitor of its obligations with respect to the subject matter of any such
indemnification, except to the extent and only to the extent that the
Indemnitor suffers prejudice as a result of such failure.  Each Indemnitee
shall, without compensation, afford such reasonable cooperation as may be
requested by the Indemnitor in the defense, pursuit or settlement of any claim
or matter as to which indemnification is required hereunder, including without
limitation by making available to the Indemnitor all pertinent non-privileged
information and non-privileged documents under the control of the Indemnitee.

                        ARTICLE IX:  GENERAL PROVISIONS

                 9.01     Equitable Relief; Specific Performance.  Each
party hereto acknowledges that with the exception of covenants which provide
only for the payment of money, a violation of any of the covenants contained in
this Agreement may cause irreparable damage to the other for which damages or
other monetary relief may be inadequate.  Accordingly, each party hereto agrees
that in the event of a breach by it of any of the covenants contained in this
Agreement (other than covenants providing only for the payment of money), the
other party shall, in addition to all other available remedies, have the right
to obtain specific performance or such other injunctive relief or other
equitable relief from a court of competent jurisdiction as may be necessary or
appropriate.

                 9.02     Further Assurances.  The parties hereto agree

                 9.03     Entire Agreement.  Except as otherwise provided in
the Transfer Agreement, this Agreement and the schedules attached hereto
constitute the entire agreement of the parties hereto with respect to the
subject matter hereof and





                                      -26-
<PAGE>   30
supersede all prior agreements, arrangements and communications of the parties
dealing with such subject matter, whether oral or written.  No other promise,
agreement, understanding, or representation will be binding unless made in
writing and signed by the parties hereto.  All amendments to this Agreement
must be in writing and signed by all of the parties hereto.

                 9.04     Governing Law.  This Agreement and the rights
and obligations of the parties hereto shall be governed by and construed in
accordance with the internal laws of the State of Delaware, without giving
affect to the conflicts of law principles thereof, in every respect, including
but not limited to validity, interpretation and performance, notwithstanding
that one or more of the parties to this Agreement may now be or hereafter
become domiciled in or a resident of another state or a foreign country.

                 9.05     Non-Exclusive Forum.  The parties hereto
agree that the state court located in Cook County, Illinois and the Federal
District Court for the Northern District of Illinois located in Chicago,
Illinois shall each have non-exclusive jurisdiction to adjudicate any dispute
between the parties hereto which arises out of or in connection with this
Agreement.

                 9.06     Relationship of Parties.  Nothing provided in
this Agreement or in the schedules attached hereto shall be deemed to create
any relationship between the parties of employment, agency, partnership or
joint venture.

                 9.07     Severability.  In the event that any
provision of this Agreement is held illegal or invalid for any reason, such
illegality or invalidity shall at the option of the party against whom the same
is asserted not affect the remaining parts of this Agreement, but this
Agreement shall be construed and enforced as if that illegal and invalid
provision had never been inserted herein.

                 9.08     Notices.  All notices and other communications under
this Agreement shall be in writing and may be given by any of the following

                          sublicense in question; provided, that with respect
                          to any such Net Revenues which are received by NCT
                          pursuant to or in connection with the ANVT license
                          referred to in Section 2.04(b)(i), above, such

                          Net Revenues which are received by NCT pursuant to or

                 3.06  Additional Royalties.  NCT shall pay a royalty to WEM of

this Agreement pursuant to or in connection with the ANVT Licenses referred to
in Section 2.04(b)(i) and the other license rights referred to in any of
Sections 2.04(b) through 2.04(d), above (but with respect to such Sections
2.04(b)(ii) through 2.04(b)(v), 2.04(c) and 2.04(d) above, only if the product
or products in question constitute or include an Electronic Muffler).  Except
to the extent otherwise provided in the immediately preceding sentence of this
Section 3.06, with respect to any license rights referred to in any of Sections
2.04(b)(ii) through (v), 2.04(c) and 2.04(d) above, NCT shall pay a royalty to
WEM on the same basis as is provided with respect to the licenses and
sublicenses which are described in Section 3.05 above; provided, that with
respect to the licenses referred to in Section 2.04(b), such royalty obligation
shall not apply with respect to either (i) the sale or lease of any products
thereunder prior to the date on which NCT became entitled to and received
royalties for any such sale or lease pursuant to the assignment by ANVT to NCT
of the licensor's (or sublicensor's) rights thereunder, or (ii) that period of
time for which complete royalties were paid thereunder prior to the
aforementioned assignment by ANVT to NCT of the licensor's (or sublicensor's)
rights thereunder and for which no payment was actually received by NCT.
Royalties payable by NCT to WEM pursuant to Section 3.05 above shall be
credited to the royalties payable under this Section 3.06 to the extent (but
only to the extent) that the Net Revenues or other amounts referred to in this
Section 3.06 are attributable to the sale or lease of a product, or the grant
of a license or sublicense, for which a royalty is payable by NCT to WEM
pursuant to Section 3.05 above.

                 3.07             Accrual of Royalty Obligations.  The
obligation to pay a royalty due under this Agreement in connection with the
sale of a product shall arise upon consummation of the sale in question.  The
obligation to pay a royalty due under this Agreement in connection with a
lease, sublicense or license to a third party shall arise upon the receipt by
the royalty obligor of the payment to it under such lease, license or
sublicense agreement to which the royalty relates.

                 3.08             Royalty Payment Dates.  The royalties
described in this Article III shall be paid in arrears on a quarterly basis,
and all royalty payments shall be accompanied by a statement showing the costs
incurred or Net Revenues received, as applicable, and a calculation of the
royalties due for the applicable calendar quarter.  Royalty payments shall be
due not later than the thirtieth (30th) day following the end of each calendar
quarter from and after the date of this Agreement.

                 3.09             Books and Records.  WEM and NCT shall have
the right to inspect and audit the relevant books and records of the other, and
each shall cause its Affiliates to also permit the relevant books and records
of each Affiliate to be inspected and audited, upon reasonable advance notice
and during normal business hours for the sole purpose of verifying amounts of
royalties due pursuant to this Agreement; provided, that each party shall have
the right to conduct any such audit and inspection not more often than two
times during each calendar year.  The cost of any such audit shall be borne by
the requesting party unless the audit reveals an underpayment of two percent or
more with respect to any specific royalty or with respect to the aggregate
amount of all types of royalties payable by such party for any calendar quarter
or for one year in total, in which case the cost of the audit shall be borne by
the audited party.

                 3.10             Interest.  Any amounts for royalties not paid
when due shall bear interest for each day on which any such amounts remain due
and unpaid at the lesser of (i) an annual rate of four percentage points in
excess of the interest rate identified as the prime rate of interest in the
Wall Street Journal, or (ii) the maximum interest rate permitted by applicable
law.

                 3.11             Royalty Exceptions.  Notwithstanding anything
provided herein to the contrary, a party obligated to pay royalties to the
other party to this Agreement shall not be obligated to pay such royalties to
such other party for, or during, any period during which such other party or an
Affiliate of that other party is in material breach of any provision of the
Transfer Agreement or any other of the Restructuring Agreements.  In addition,
no royalties shall be due with respect to any product which, or any license or
any





                                      -20-
<PAGE>   24
sublicense pursuant to which a product is manufactured, sold, leased or used if
the product in question is one which, incorporates or is based only upon (i)
technology covered by the claim of a patent which has expired, (ii) any portion
of the NCT Technology or Improvements, as the case may be, with the exception
of issued patents, which does not continue to constitute confidential and
proprietary information of the licensor thereof as to which the exclusive
rights granted hereunder can be enforced, or (iii) both; provided, that the
foregoing provisions of this sentence shall not apply with respect to, and
during the period that WEM or NCT, as the case may be, continues, in its
capacity as the licensor or sublicensor, to receive revenues pursuant to
licenses or sublicenses granted by such party prior to the expiration of the
patent or patents in question or prior to the time that the enforceability of
the exclusive rights granted hereunder became unenforceable with respect to the
portion of the NCT Technology or the Improvements, as the case may be, in
question.  Notwithstanding anything else contained herein, royalties otherwise
due hereunder shall not be payable to the extent expressly provided in the
Support, Research and Development Agreement constituting one of the
Restructuring Agreements.

            ARTICLE IV:  DELIVERY OF INTELLECTUAL PROPERTY MATERIALS

                 4.01             Delivery at Closing.  Contemporaneously with
the execution of this Agreement, NCT shall deliver or cause to be delivered to
WEM the items identified in SCHEDULE 4.01(a). Not later than 14 days following
the execution of this Agreement, NCT shall deliver or cause to be delivered to
WEM copies of all documents and materials (whether written or in
machine-readable format on magnetic or other media) and things which contain,
set forth, explain or otherwise relate to that part of the NCT Technology
identified in SCHEDULE 4.01(b), and shall deliver to WEM, from time to time
upon request, all such items with respect to any other part of the NCT
Technology.  Without limiting the generality of the foregoing, NCT shall
furnish to WEM at the Closing copies of all source codes for all software
included within the NCT Technology identified in SCHEDULES 4.01(a) AND 4.01(b).

                 4.02             Delivery of Improvements.  Contemporaneously
with the delivery of the royalty calculation reports described in Section 3.08,
above, each party hereto shall furnish a written report to the other describing
in reasonable detail all Improvements to the NCT Technology made or caused to
be made by such party or any of its Affiliates during the immediately preceding
calendar quarter or, if none, reciting that no such Improvements have been made
or acquired by such party or its Affiliates during such quarter.  With respect
to all Improvements disclosed in each such report, the party submitting the
report shall also deliver to the recipient of the report, as soon as is





                                      -21-
<PAGE>   25
reasonably practicable following a written request, copies of all documents and
materials (whether written or in machine-readable format on magnetic or other
media) and things which contain, set forth, explain or otherwise relate to the
intellectual property comprising each of the Improvements in question
(including without limitation copies of source codes).

                          ARTICLE V:  OTHER COVENANTS

                 5.01             Restrictions Concerning Exclusive Field.  NCT
shall not, and shall not permit its Affiliates or any third parties to, grant
any licenses or sublicenses of the NCT Technology for use in the Exclusive
Field to any third party subsequent to the date of this Agreement.  In
addition, with the exception of amendments to economic terms and conditions for
the limited purpose of increasing royalty rates and with the additional
exception of the affirming license agreement between NCT and Arvin Industries,
Inc. more particularly described in SCHEDULE 5.05(b), NCT shall not, and shall
not permit any of its Affiliates or any third party to, amend or alter any of
the ANVT Licenses or any other pre-existing licenses or sublicenses of the NCT
Technology that involve rights within or pertaining to the Exclusive Field.

                 5.02             Notice of Licenses.  NCT shall itself, and
shall cause its Affiliates to, notify WEM in writing at least twenty (20)
business days in advance of granting to any third party any subsequent licenses
or sublicenses of any type with respect to any of the NCT Technology.  Such
written notice shall include or be accompanied by a certificate of an officer
of NCT, or other evidence reasonably satisfactory to WEM, reflecting that, and
NCT hereby covenants that, the proposed license or sublicense (i) will not
infringe upon WEM's exclusive rights in the Exclusive Field, (ii) will either
include a grant-back provision to the licensor that will permit WEM and its
Affiliates to use, as a part of the license granted hereunder, all Improvements
made by the licensee or, if such a grant-back provision is not included, that
such proposed license or sublicense will not include any rights to any of the
Improvements described in Section 2.08 above, and (iii) to the extent that any
grant-back provisions will be included in such proposed license or sublicense,
will include provisions of the type described in Section 5.03 below.  NCT shall
use its reasonable best efforts to cause any subsequent license or sublicense
(or permitted amendment of any existing license or sublicense) to include a
grant-back provision to the licensor that will permit WEM and its Affiliates to
use, as a part of the license granted hereunder, all Improvements made by the
licensee.

                 5.03             Third Party Beneficiary.  NCT shall cause any
subsequent license or sublicense of the NCT Technology to include a provision
expressly designating WEM as a third





                                      -22-
<PAGE>   26
party beneficiary of the obligations of the licensor and licensee under such
license to ensure WEM's access to Improvements and its ability to enforce the
provisions of Sections 5.01 and 5.02, above.

                 5.04             Maintenance and Enforcement.  NCT shall pay
or cause to be paid when due all maintenance fees and annuities for each of the
patents covering any of the NCT Technology, and shall furnish to WEM, not less
often than quarterly, a report reflecting in reasonable detail the status of
such maintenance fees and annuities payments.  NCT shall also take all action
reasonably required to enforce the patents covering the NCT Technology against
infringement by third parties or other challenge (including without limitation
claims of invalidity or unenforceability), and shall promptly furnish WEM with
written notice of any actual or threatened action or proceeding concerning the
same.  In addition, NCT shall furnish to WEM, upon request from time to time,
written reports describing in reasonable detail the status of any such matters.
In the event that NCT is unable or otherwise does not intend to (i) pay any
such patent maintenance fees or annuities, or (ii) take any action concerning
any such infringement or other challenge, NCT shall promptly notify WEM to that
effect, which notice shall in any event be given not later than the last day of
such period of time as would allow WEM sufficient time to make any such payment
or take action concerning any such infringement or other challenge prior to the
expiration of any rights to do so.  If NCT fails to (i) pay any such patent
maintenance fees or annuities, or (ii) take any action concerning any such
infringement or other challenge, WEM shall have the right, but not the
obligation, to make such payment or to take such action, in its own name or (in
WEM's discretion) in the name and on behalf of NCT, as it deems appropriate to
defend the NCT Technology from such infringement or other challenge, and NCT
shall take all such action, at its own expense, as may be reasonably requested
by WEM to cooperate with such action by WEM.

                 5.05             Warranties and Representations.  NCT hereby
warrants and represents to WEM as follows:  (i) NCT is the owner of the NCT
Patents, free and clear of any liens, encumbrances or claims (but subject to the
licenses identified in SCHEDULE 5.05(A), none of which contain any provisions
which could result in a loss of ownership or any impairment of the rights
granted hereunder or of NCT's right to grant the rights hereunder), and except
as otherwise expressly set out in SCHEDULE 5.05(A) hereto, is the owner of the
NCT Technology or possesses nonterminable (except to the extent that any patents
covering such technology are adjudicated to be invalid or unenforceable, and NCT
hereby represents and warrants that it has no knowledge of any pending or
threatened proceedings, or any basis therefor, which could have such result),
perpetual worldwide license





                                      -23-
<PAGE>   27
rights thereto which include the right to grant the license thereto pursuant to
this Agreement, in each case free and clear of any liens, encumbrances or
claims; (ii) SCHEDULE 5.05(b) hereto contains a complete description of each of
the rights of third parties to ANVT Technology with respect to the fields of
application referred to in Section 2.02 above as to which such Section 2.02
recites that WEM is not granted a license hereunder to use ANVT Technology;
(iii) SCHEDULE 5.05(b) hereto contains a complete description of each of the
rights of the third parties referred to in Section 2.04 as constituting
exceptions to the otherwise exclusive rights of WEM granted pursuant to this
Agreement and no other rights have been granted by any of the NCT Parties or,
to the Knowledge of the NCT Parties, upon due inquiry by or on behalf of NCT,
by ANVT which could infringe upon such exclusivity; and (iv) no representation
or warranty made herein by NCT, and no schedule attached hereto, contains any
untrue statement of a material fact or omits to state a material fact or to
include any information necessary to make such representation, warranty or
schedule not misleading or incomplete in light of the circumstances under which
it is made or prepared, as the case may be.

             ARTICLE VI:  TRADEMARKS, SERVICE MARKS AND TRADE NAMES

                 6.01             WNCT Marks.  NCT hereby agrees that WEM
shall, at all times from and after the date of this Agreement, have the right
to use the Names and Marks of WALKER NOISE CANCELLATION TECHNOLOGIES, WNCT,
WALKER ELECTRONIC SILENCERS, WALKER ELECTRONIC SILENCING and WALKER INDUSTRIAL
SILENCERS in connection with its business and products which incorporate the
NCT Technology.  NCT hereby agrees that it shall not oppose or object to WEM's
use or registration of the aforesaid names or marks.  In addition, NCT shall
cause such of its Affiliates as may be designated by WEM from time to time to
execute, either contemporaneously with NCT's execution of this Agreement or
thereafter, an acknowledgment in form reasonably satisfactory to WEM confirming
the rights of WEM under this Section 6.01 and Section 6.02 below.

                 6.02             CPH Marks.  NCT hereby acknowledges and
agrees that pursuant to a separate license agreement of even date between CPH
and WEM (the "CPH License"), WEM shall have the right to use the names and
marks of Chaplin Patents Holding Co., Inc. (the "CPH Marks") in connection with
its business and products which incorporate technology licensed to WEM under
such other license agreement.  NCT hereby agrees that it shall not oppose or
object to WEM's use of the CPH Marks.

                         ARTICLE VII:  CONFIDENTIALITY

                 7.01             Confidentiality Covenants.  Except as
expressly otherwise provided herein, each of the parties agrees that it shall
not disclose, nor shall it induce or permit others to disclose, to any third
party any of the terms and conditions of this Agreement or information learned
in course of inspecting the books and records of the other party or pertaining
to any intellectual property or other technology licensed to it by the other
party hereto; provided, that such information may be disclosed to the extent
necessary to give effect to any license or sublicense contemplated or otherwise
permitted by this Agreement.  Each party shall, prior to disclosing any such
information in accordance with this Section 7.01, cause each person or entity
given access to such information to enter into a binding and enforceable
agreement pursuant to which the recipient of such information agrees to be
bound by the covenants of this Article VII for the benefit of the licensor (or
sublicensor, as the case may be) and for the benefit of WEM or NCT (whichever
is not the licensor or sublicensor in question, as the case may be).
Notwithstanding anything provided herein to the contrary, the covenants
restricting disclosure set forth in this Section 7.01 shall not apply with
respect to information or other items that the recipient thereof can show (i)
was known or becomes known to the general public without disclosure by such
recipient (or any Affiliate of such recipient), (ii) was already known by the
recipient thereof before its disclosure by a party hereto, or (iii) was legally
acquired by the recipient thereof from another party and in good faith,
provided that such disclosure by the other party was not a breach of any
agreement or in derogation of any confidential relationship between such other
party and any other party hereto.  In addition, and notwithstanding the
foregoing, if legal counsel for either NCT, WEM or any of their respective
Affiliates is of the opinion that a statement, announcement or filing involving
the disclosure of any of the terms or conditions hereof is required by law or
regulation or by the rules of any stock exchange on which its securities are
traded, then such entity may issue a statement or announcement or make a
filing, in each instance limited solely to that which legal counsel for such
party advises is required under law or such rules.  A party as to which any
such statement, announcement or filing is proposed on its own behalf or on
behalf of an Affiliate thereof shall provide a copy thereof to the other party
for its prior review, and shall use its reasonable best efforts to cause any
such filing to be accomplished on a basis that includes the redaction of all
economic terms and conditions (including without limitation the amounts of
royalties) and any other terms and conditions as to which redaction is
reasonably requested by such other party, and shall cooperate with and permit
such other party to participate in the process of seeking such redaction.

                         ARTICLE VIII:  INDEMNIFICATION

                 8.01             Indemnification by NCT.  NCT hereby agrees to
indemnify and to hold WEM and its Affiliates, and the officers, directors,
shareholders, agents and employees of each of them (collectively the "WEM
Indemnitees" and singly a "WEM Indemnitee") harmless from and against any and
all liability, loss, damage or injury, together with all reasonable costs and
expenses relating thereto (including but not limited to legal and accounting
fees) arising out of or resulting from any claim which is asserted against any
of the WEM Indemnitees which includes any allegation of any product liability
claim concerning design based upon any defective design of the NCT Technology
(except with respect to but only to the extent of, allegations of defective
design pertaining only to Improvements made by or on behalf of WEM other than
those made on behalf of WEM by NCT).

                 8.02             Indemnification by WEM.  WEM hereby agrees to
indemnify and hold NCT, its Affiliates, and the shareholders, directors,
officers, employees and agents of each of them (collectively the "NCT
Indemnitees" and singly a "NCT Indemnitee") harmless from and against any and
all liability, loss, damage or injury, together with all reasonable costs and
expenses relating thereto (including but not limited to legal and accounting
fees) arising out of or resulting from any claim which is asserted against any
of the NCT Indemnitees involving any allegation of any products liability in
connection with a product manufactured by or on behalf of WEM or any of its
Affiliates which incorporated any of the NCT Technology; provided that with
respect to any such product which incorporates any of the NCT Technology, the
obligation to provide indemnification under this Section 8.02 shall not apply
to the extent that such claim includes or is asserted in connection with any
allegation of defective design in the NCT Technology (except with respect to
but only to the extent of, allegations of defective design pertaining only to
Improvements made by or on behalf of WEM other than those made on behalf of WEM
by NCT).

                 8.03             Control of Contest.  For purposes of this
Section 8, the party entitled to indemnification is referred to as the
"Indemnitee" and the party obligated to provide indemnification is referred to
as the "Indemnitor."  The Indemnitor shall have the right, at its own expense,
to control any claim or matter as to which such Indemnitor is obligated to
provide indemnification pursuant to any provision of this Agreement.  This
shall include the right to designate the attorneys and other professionals who
shall defend or pursue any such claim or matter and to make the decision
whether to pursue any such claim or matter to a judgment, to settle any such
claim or matter, or to agree to any such claim or matter without any contest
thereof; provided, that (i) the Indemnitor shall obtain the prior





                                      -26-
<PAGE>   30
approval of the Indemnitee(s) to legal counsel engaged to defend or pursue any
such claim or matter, which approval shall not be unreasonably withheld, and
(ii) no Indemnitor shall have the right to agree to settle any claim or matter
in a manner that would adversely affect the interest of any Indemnitee without
the written consent of the adversely affected Indemnitee or Indemnitees, as the
case may be, which consent shall not be unreasonably withheld.  From and after
the date on which the Indemnitor assumes control of the defense of any manner
as to which indemnification is required hereunder, the Indemnitor shall not be
obligated to pay any attorneys' fees incurred by the Indemnitee(s) for
additional counsel retained directly by the Indemnitee(s) without the consent
of the Indemnitor; provided, that in the event that any Indemnitor is unable or
unwilling to satisfy its indemnification obligation hereunder, the
Indemnitee(s) shall be entitled to engage at that Indemnitor's expense the
attorneys and other professionals who shall defend or pursue such claim or
matter and shall also be entitled to make any decision whether to defend,
pursue or settle such claim or matter.

                 8.04             Notice and Cooperation.  The Indemnitee shall
promptly notify the Indemnitor upon learning of any claim or matter as to which
indemnification is required pursuant to this Section 8; provided, that the
failure to provide any such notice to an Indemnitor shall not relieve that
Indemnitor of its obligations with respect to the subject matter of any such
indemnification, except to the extent and only to the extent that the Indemnitor
suffers prejudice as a result of such failure.  Each Indemnitee shall, without
compensation, afford such reasonable cooperation as may be requested by the
Indemnitor in the defense, pursuit or settlement of any claim or matter as to
which indemnification is required hereunder, including without limitation by
making available to the Indemnitor all pertinent non-privileged information and

2.04.  Information of either party disclosed to the other in connection with
the access and use of computer equipment provided under this Section 2.04 shall
be treated as Confidential Information.  NCT hereby grants to Walker an option
to purchase the aforementioned computer equipment and software (or, with
respect to software, NCT's rights therein) to which access and use is granted
under this Section 2.04, which option may be exercised by written notice from
WEM to NCT within 45 days following the date on which NCT gives notice to WEM
of NCT's bona fide intention to move such computer equipment (or any part
thereof) to a different location or to otherwise dispose of such equipment,
which notice shall be given not less than 20 days prior to any such movement or
other disposition.  In the event that WEM elects to exercise the option
provided hereunder, the purchase price for such equipment and software shall be
the lesser of (i) NCT's net book value at time of purchase or (ii) the fair
market value of such items.  If the parties are unable to agree upon the fair
market value of such items, each party shall prepare a list of three commercial
appraisers having experience in the appraisal of such items.  Any appraiser
which appears on both lists shall be engaged by the parties to determine the
fair market value of such items; provided, that if more than one appraiser
appears on both lists, the appraiser which occupies the highest order of
preference on the lists shall be engaged.  If no appraiser appears on either
list, the two appraisers identified as the respective first choices of each
party shall be engaged to select a third appraiser who shall in turn determine
the fair market value of the items in question.  The fees of the appraiser or
appraisers, as the case may be, shall be borne equally by the parties.  NCT
shall deliver such documents and take such other action as is reasonably
requested by WEM to effectively transfer such items to WEM, free and clear of
all liens, encumbrances or other rights.

                 ARTICLE III -- FUTURE RESEARCH AND DEVELOPMENT

Notwithstanding anything provided herein to the contrary, NCT shall not
perform, and shall not be entitled to compensation for, any Future Development
Activities that would cause the amount of any monthly invoice to exceed any
maximum amount which may be identified by WEM when submitting or amending any
request for Future Development Activities.  WEM shall pay or cause to be paid
each of the aforementioned invoices not later than 45 days following receipt of
each invoice by WEM; provided, that WEM shall be obligated to pay each invoice
not later than 30 days following receipt thereof if NCT submits to WEM with
such invoice an offer in conspicuous written form to accept a discounted
payment of ninety-seven percent (97%) in satisfaction thereof.

                 3.03  Amendment or Termination of Future Development Services.
WEM shall have the right at all times to amend the scope of, or to terminate,
any or all of the Future Development Activities by giving written notice to
NCT, which notice shall describe in reasonable detail the amendment or
termination in question.  An amendment or termination of Future Development
Activities shall not affect any rights or obligations of a party pertaining to
any period prior to such amendment or termination.

the owner of the Confidential Information in question.  In addition, and
notwithstanding the foregoing, if legal counsel for either WEM or any of the
NCT Parties or any of their respective Affiliates is of the opinion that a
statement, announcement or filing involving the disclosure of any of the terms
or conditions hereof is required by law or regulation or by the rules of any
stock exchange on which its securities are traded, then such entity may issue a
statement or announcement or make a filing, in each instance limited solely to
that which legal counsel for such party advises is required under law or such
rules.  A party as to which any such statement, announcement or filing is

reasonable best efforts to cause any such filing to be accomplished on a basis
that includes the redaction of all economic terms and conditions (including
without limitation the amounts of royalties) and any other information, terms
or conditions as to which redaction is reasonably requested by such other
party, and shall cooperate with and permit such other party to participate in
the process of seeking such redaction.

                 5.02  Return and Acknowledgment.  Except to the extent

acknowledge that WEM shall have the right to employ (or to engage as an
independent contractor) any employee or former employee of any of the NCT
Parties (or any Affiliates thereof) following a termination of the employee's
employment by the NCT Party (or its Affiliate) in question.  Each of the NCT
Parties shall, as soon as is reasonably practicable following the execution of
this Agreement, modify any confidentiality or other restrictive covenants in
favor of the NCT Party in question such that these covenants would not bar the
employees of such NCT Party from employment with WEM (or any Affiliate of WEM)

promptly effect the same modification of any confidentiality or other
restrictive covenants in favor of an NCT Party to which any former employee of
any NCT Party is bound.

                 6.02  Use of Information.  In the event that WEM employs any
former employee of an NCT Party, WEM shall use its reasonable best efforts to
cause the employee to identify all Confidential Information of the NCT Party

<PAGE>   14
except those who have a need to know that information to fulfill the purposes
for which WEM may use such Confidential Information; provided, that prior to
any such limited disclosure, WEM shall obtain from each person or entity given
access to such Confidential Information an executed Secrecy Agreement in form
and substance reasonably satisfactory to the NCT Party from which the
Confidential Information was derived.

                 6.03  Equitable Relief.  WEM acknowledges that a violation of
the covenants of WEM contained in this Section 6 may cause irreparable damage
to one or more of the NCT Parties for which other remedies may be inadequate.
Accordingly, WEM agrees that, in the event of a breach by WEM of any of the
covenants made in this Section 6, the NCT Parties shall (in addition to all
other available remedies) have the right to obtain such injunctive or other
equitable relief from a court of competent jurisdiction as may be necessary or
appropriate.

with any allegations of defective design in the Licensed Technology.

                 7.03  Control of Contest.  For purposes of this Section 7, the
party entitled to indemnification is referred to as the "Indemnitee" and the
party obligated to provide indemnification is referred to as the "Indemnitor."
Each Indemnitor shall have the right, at its own expense, to control any claim
or matter as to which such Indemnitor is obligated to provide indemnification
pursuant to any provision of this Agreement; provided, that if more than one
Indemnitor is obligated to provide indemnification, the Indemnitors shall
exercise such control jointly.  This shall include the right to designate the
attorneys and other professionals who shall defend or pursue any such claim or
matter and to make the decision whether to pursue any such claim or matter to a
judgment, to settle any such claim or matter, or to agree to any such claim or
matter without any contest thereof; provided, that (i) the Indemnitor or
Indemnitors, as the case may be, shall obtain the prior approval of the
Indemnitee to legal counsel engaged to defend or pursue any such claim or
matter, which approval shall not be unreasonably withheld, and (ii) no
Indemnitor shall have the right to agree to settle any claim or matter in a
manner that would adversely affect the interest of any Indemnitee without the
written consent of the adversely affected Indemnitee or Indemnitees, as the
case may be, which consent shall not be unreasonably withheld.  From and after
the date on which the Indemnitor(s) assumes control of the defense of any
manner as to which indemnification is required hereunder, the Indemnitor(s)
shall not be obligated to pay any attorneys' fees incurred by the Indemnitee(s)
for additional counsel retained directly by the Indemnitee(s) without the
consent of the Indemnitor(s); provided, that in the event that any Indemnitor
is unable or unwilling to satisfy its indemnification obligation hereunder, the
Indemnitee(s) shall be entitled to engage at that Indemnitor's expense the
attorneys and other professionals who shall defend or pursue such claim or
matter and shall also be entitled to make any decision whether to defend,
pursue or settle such claim or matter.

                 7.04  Notice and Cooperation.  The Indemnitee shall promptly
notify each Indemnitor upon learning of claim or matter as to which
indemnification is required pursuant to this Section 7; provided, that the
failure to provide any such notice to an Indemnitor shall not relieve that
Indemnitor of its obligations with respect to the subject matter of any such
indemnification, except to the extent and only to the extent that the
Indemnitor suffers prejudice as a result of such failure.  Each Indemnitee
shall, without compensation, afford such reasonable cooperation as may be
requested by the Indemnitor in the defense, pursuit or





                                      -12-
<PAGE>   16

settlement of any claim or matter as to which indemnification is required
hereunder, including without limitation by making available to each Indemnitor
all pertinent non-privileged information and non-privileged documents under the
control of the Indemnitee.

                 7.05  Joint and Several Obligations.  Neither the inability or
unwillingness of one or more Indemnitors to defend, hold harmless or indemnify
any Indemnitee as provided in this Agreement, nor the insolvency of one or more
Indemnitors, the release of or compromise of claims with one or more
Indemnitors, the failure of any Indemnitee to pursue one or more Indemnitors or
a legal defense asserted by one or more Indemnitors shall relieve any of the
other Indemnitors from its obligation to defend, hold harmless and indemnify
which is contained in this Agreement.  Neither the modification of this
Agreement, nor any merger, consolidation, corporate change, change in business,
change in ownership, transfer of assets or other event or occurrence of a like
or different nature affecting any of the parties hereto shall affect the
responsibility of any Indemnitor nor relieve any Indemnitor of its obligation
to defend, hold harmless or indemnify which is contained in this Agreement.

and all matters, whether now known or unknown and whether specifically
