                                  THE COMPANY

         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 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,
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 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.

         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.
called OnActive Technologies, L.L.C. which is developing Flat Panel
Transducer(TM) ("FPT(TM)") systems utilizing TopDown Surround Sound(TM)
("TDSS(TM)") for automotive applications.

         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
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





<PAGE>   6
requirements.  The funding from these sources, if realized, will reduce the
Company's dependence on engineering and development funding.

         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 June 30, 1996 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.

         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.

         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.  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"),
Applied Acoustic Research, L.L.C.  ("AAR") and Hoover Universal, Inc.
("Hoover") (a wholly owned subsidiary of Johnson Controls, Inc.), 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.

         In February 1995 the Company purchased from 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.




<PAGE>   7
The Company and Foster remain active in the Far East through Foster/NCT
Headsets International, Ltd.  ("FNH") and NCT Far East, Inc.  ("NCTFE") which
are 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.

         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 July 18, 1996, the Company
had 75 employees, including 32 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 functions 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 facilities
are located at 1025 West Nursery Road, Linthicum, Maryland 21090; telephone
number (410) 636-8700.  NCT maintains sales and marketing offices at One 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.

         not previously recorded with respect to its joint venture with Walker
         amounting to $3,581,682.

         stock options, warrants and, where applicable in 1991, outstanding
         shares of Series A and Series B Convertible Preferred Stock, since
         their effect would be antidilutive.

                                  THE OFFERING

     This offering consists of the resale of 4,093,135 shares of Common Stock
which are issuable upon the exercise of outstanding options to purchase shares
of Common Stock (the "Option Shares") granted under the 1992 Plan or upon the 
grant of restricted Common Stock awards under the 1992 Plan to persons who may
be deemed "affiliates" of the Company, as that term is defined under the
Securities Act, all of which may be offered for sale by such persons as Selling
Stockholders (see "Selling Stockholders").  The proceeds, if any, from the
exercise of any such options will be added to the Company's working capital. 
The Company will not receive any of the proceeds from the sale of the Option
Shares by the Selling Stockholders.
     
     In addition, this offering relates to any additional shares of Common
Stock which may become issuable upon the exercise of options to purchase shares
of Common Stock to be granted to such persons under the 1992 Plan in the future
as well as any additional shares of Common Stock which may be issued in the
future to such persons upon the grant of restricted Common Stock awards under
the 1992 Plan.  The number of any such additional shares and the names of such
persons will be set forth in a supplement to this Prospectus (see "Selling
Stockholders").





<PAGE>   11
                                  RISK FACTORS

         The shares of Common Stock offered hereby represent a speculative
investment and entail elements of risk. The following factors, in addition to
the other information included or incorporated by reference herein, should be
carefully considered before any decision is made to purchase any of the shares
of Common Stock offered hereby.

         CURRENT FINANCIAL CONDITION; CASH POSITION; INADEQUACY OF CURRENTLY
AVAILABLE FUNDS TO SUSTAIN COMPANY; LIMITATION ON ABILITY TO SELL ADDITIONAL
COMMON STOCK.  Cash, cash equivalents and short-term investments amounted to
$0.9 million at June 30, 1996, decreasing from $1.8 million at December
31, 1995.  On April 10, 1996, the Company sold 1,000,000 shares, in the 
aggregate of its Common Stock in a private placement with three institutional
investors (the "April 1996 Private Placement").  Contemporaneously, the Company
sold secured convertible term notes in the aggregate principal amount of
$1,200,000 to those institutional investors and granted them each an option to
purchase an aggregate of $3,450,000 of additional shares of the Company's
Common Stock.  The per share conversion price under the notes and the exercise
price under the options are equal to the price received by the Company for the
sale of such 1,000,000 shares subject to certain adjustments.  On August 13,
1996 the three institutional investors exercised their options and converted
their secured convertible term notes.  On August 29, 1996, the Company sold
1,753,968 shares of its Common Stock in a private placement with a Canadian
institutional investor (the "August 1996 Private Placement").  The cash raised
from the April 1996 Private Placement and the August 1996 Private Placement,
the exercise of warrants and options, including the options granted to the
three institutional investors in the April 1996 Private Placement, the funding
derived from forecasted technology licensing fees and  royalties, and product
sales and engineering and development revenue income, the operating cost
savings from the reduction in employees and reduced capital expenditures
should be sufficient to sustain the Company's anticipated future level of
operations into 1997.  However, the current available funds are not sufficient
to sustain the  Company for the next twelve months.  The period during 1997
through which the  Company can be sustained is dependent upon the level of
realization of funding  from technology license fees and 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.

         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.  In January 1996, the Company adopted a plan
that management believes should generate sufficient funds for the Company to
continue its operations into 1997.  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 referred to above, the
Company will consider fund raising alternatives.

         As a condition to the sale of Common Stock of seemed convertible term
notes to three institutional investors in the April 1996 Private Placement the
Company agreed not to sell any additional equity financing (including debt
financing with an equity component) without such investors' consent prior to
October 8, 1996 and granted the three institutional investors a right of first
refusal with respect to any such additional financing until April 10, 1997. 
The  Company's ability to raise additional capital through sales of Common
Stock  will be severely limited until the termination of these restrictions on
further  equity financing.  The Company will monitor its performance against
the plan  on a monthly basis and, if necessary, reduce its level of operations 
accordingly.  The Company believes that the plan discussed above constitutes a 
viable plan for the continuation of the Company's business into 1997.

         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.

         The Company expects to continue as a going concern, which contemplates
continuity of operations, realization of assets and satisfaction of liabilities
in the ordinary course of business and its





<PAGE>   12
financial statements have been prepared on that basis.  This 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 paragraph raise
substantial doubt at March 31, 1996, about the Company's ability to continue as
a going concern.  The Company's financial statements do not include any
adjustments relating to the recoverability of the carrying value of recorded
assets or the amount of liabilities that might result from the outcome of these
uncertainties.

         The Company has never declared nor paid dividends on its common stock
and has no present intention to do so.

         GOING CONCERN EMPHASIS PARAGRAPH IN ACCOUNTANTS' OPINION.  On March 8,
1996, Richard A. Eisner & Company, LLP issued its report on the Company's
consolidated financial statements as of and for the year ended December 31,
1995.  With respect to Note 15 to those financial statements, such report was
dated April 10, 1996.  The report of Richard A. Eisner & Company, LLP contains 
a paragraph which emphasizes certain factors which are described in Note 1 to 
the financial statements covered by the report.  This paragraph notes that such
factors raise substantial doubt as to the Company's ability to continue as a 
going concern.  See "Experts-Report of Independent Auditors" below.  
Prospective investors are urged to read carefully the report of Richard A. 
Eisner & Company, LLP as well as the consolidated financial statements of the 
Company and the notes thereto, which are incorporated herein by reference to 
Amendment No. 5 to the Company's Annual Report on Form 10-K for the year ended 
December 31, 1995, filed on June 13, 1996.

         HISTORY OF OPERATING LOSSES AND ACCUMULATED DEFICIT.  The Company
incurred a net loss of $4.1 million for the year ended December 31, 1995, and
an additional net loss of $3.9 million for the six months ended June 30,
1996. The Company's accumulated deficit at June 30, 1996 was $76.8 million,
attributable in substantial part to the costs of developing its proprietary
technology.  To achieve profitability, NCT must, independently and with
strategic allies, successfully develop, manufacture, introduce and market its
products in commercial quantities and receive fees and royalties from licensing
its proprietary technology.

         LIMITED REVENUES.  Although the Company has engaged in marketing
activities with regard to the sale or licensing of electronic systems for
Active Wave Management(TM) including systems that electronically reduce noise
and vibration based upon prototypes of such systems, its operating revenues
from inception through June 30, 1996, have been limited, aggregating
$8.4 million from the sale of such systems, $10.7 million from the
licensing of technology relating to such systems and $20.6 million from the
performance of engineering and development services, respectively.  Although
the Company has begun commercial sales of active noise attenuation and other
products in a limited number of applications, significant further development
will be necessary before many of the Company's potential products will achieve
expected commercial end-use applications.

         MATERIAL DEPENDENCE UPON CERTAIN PATENT RIGHTS; UNCERTAIN PROPRIETARY
PROTECTION.  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




<PAGE>   13
applications filed in the future will result in the issuance of a patent.
The invalidation 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.  Although the Company intends to file for extensions to certain
patents, the Company can make no assurances that the U.S. or foreign government
patent authorities will grant such extensions.

         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 rights to
protect present and future technology of the Company.

         There has been a claim challenging the use of one of the Company's
trademarks and an interference proceeding has been initiated with respect to
one of the Company's patent applications.  There has also  been an inquiry
regarding the product design configuration of one of the Company's products as
it relates to a patent held by another company.  The Company believes that such
claims and inquiry are without merit and intends to oppose them vigorously.
Moreover, if such inquiry proves to have any merit, the Company believes it
could, without significant cost, modify its product design configuration so as
to avoid infringement.  The Company does not believe that any damages or costs
it may incur as a result of such claims or inquiry would have a material
adverse effect on the financial condition 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.

         RAPID TECHNOLOGICAL CHANGE.  Active Wave Management(TM) is an evolving
industry, characterized by rapid technological change. The Company intends to
engage continually in research and development activities, including the
improvement of current products and development of new products.  There can be
no assurance, however, that active noise and vibration attenuation or other
applications of Active Wave Management(TM) will be accepted by the commercial
marketplace, that the introduction of new products or the development of new
technologies by others will not render the Company's products obsolete or
unmarketable, or that the Company will be able to hire and retain adequate
research personnel or be able to finance research activities in this regard.

         RELIANCE UPON STRATEGIC ALLIANCES; COMMERCIAL ACCEPTANCE OF
END-PRODUCTS. The Company and certain of its wholly owned subsidiaries have
entered into agreements to establish 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 its technology and contribute a nominal amount of initial
capital and that the other party provide substantially all of the funding to
support the alliance.  In exchange for this funding, the other party generally
receives 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.  At June 30, 1996, there were no
preferred distributions due to joint venture partners from future profits of
the joint ventures.

         The Company conducts its marketing efforts primarily by identifying
specific market segments for active noise and vibration attenuation and other
Active Wave Management (TM) products and,




<PAGE>   14
thereafter, seeking to establish strategic alliances with major domestic and
international business concerns to support product development, and to
manufacture and distribute products for such market segments.  The Company's
ability to enter into new markets is materially dependent upon determinations
by such concerns that the Company's products are suitable for use in their
respective end-products, and on the ability and willingness of those concerns
to market such products successfully.  During 1995 and the first quarter of
1996, active headset product sales did not increase at the rate previously
anticipated and orders for active vehicular mufflers, kitchen exhaust and HVAC
fan quieting systems and industrial headsets were not received at volumes or
within time frames that had been anticipated by the Company.

         The Company arranges for the supply of actuators, integrated circuits
and other electronic components for its active control systems through
alliances with manufacturers the Company believes will serve as dependable
sources of supply.  The Company makes no assurances that these concerns will
meet the Company's and its customers' needs for quality components in
sufficient quantities at commercially reasonable prices.

         CUMULATIVE LOSSES IN JOINT VENTURES.  When the Company's share of
cumulative losses in a strategic alliance exceeds its investment and the
Company has no obligation to fund such additional losses, the Company suspends
applying the equity method of accounting for its investment in such alliance.
The aggregate amount of losses in the Company's strategic alliances in excess
of the Company's investments which has not been recorded was zero at June 30,
1996.  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.

         DEPENDENCE UPON EXECUTIVE OFFICERS AND OTHER KEY PERSONNEL. The
Company's operations are, and for the proximate future will be, materially
dependent upon the efforts of its executive officers and key technical
employees, all of whom serve the Company on a full-time basis but none of whom
are contractually obligated to remain in the Company's employ for any material
term.  Moreover, the Company's growth and expansion into new product
applications could require additional expertise in areas such as manufacturing,
marketing and distribution, which would place increased demands on the
Company's resources and would require the addition of new personnel and the
development of additional expertise by existing personnel.  Certain academic
consultants serve the Company on a part-time basis, and could terminate their
relationship with the Company at any time.

         Certain employees and consultants of the Company have been  approached
by the Company's competitors, and no assurances can be given that the
competition will not successfully recruit such personnel.  The loss of key
personnel or the failure to recruit necessary additional personnel could impede
the achievement of the Company's development, commercialization and marketing
objectives.

         AGREEMENTS WITH RELATED PARTIES; COMMISSIONS AND EXCLUSIVE
DISTRIBUTORSHIPS.  In 1993 the Company entered into four agreements with
QuietPower Systems, Inc. ("QPS") (formerly Active Acoustical Solutions, Inc.)
and in 1994 entered into a fifth agreement with QPS.  QPS is 33% owned by
Environmental Research Information, Inc. ("ERI") and 2% owned by Jay M. Haft,
Co-Chairman and Chief Executive Officer of the Company.  Michael J. Parrella,
President of the Company owns approximately 12% of the outstanding capital of
ERI and Mr. Haft shares investment control over an additional 24% of the
outstanding capital of ERI.  Under these agreements, QPS is given rights to
market certain of the Company's products and technologies to electric and/or
natural gas utilities and for use in or with feeder bowls.  In one of these
agreements, QPS's rights are on an exclusive basis so long as QPS meets certain
performance criteria relating to marketing efforts and sales performance.
Under one of these agreements, QPS is entitled to receive a sales commission
equal to 129% of QPS's marketing




<PAGE>   15
expenses attributable to the marketing of the products in question, which
expenses are to be deemed to be the lesser of QPS's actual expenses or 35% of
the revenues received by the Company from the sale of such products.
Commissions and fees  payable under all of the other agreements are in
accordance with the Company's standard terms and conditions and do not exceed
6%.  As of the date of this Prospectus, the Company has not been required to
pay any commissions to QPS under these agreements. 

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

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

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

         In May 1996, the Company and QSI entered into a third letter agreement
which revised the payment schedules for QSI's payment to the Company of the
balance of the exclusivity fee and the outstanding indebtedness for other
amounts owed the Company.  Under this letter agreement, if QSI does not pay the
full amount of arrearages in the payment of the exclusivity fee by June 15,
1996 or defaults in the timely payment of any installment of the other
indebtedness, the Master Agreement and all rights granted to QSI thereunder
terminate.  The letter agreement also amends certain provisions concerning






<PAGE>   16
royalties and administrative matters which should not materially adversely
effect the Company's economic rights under the Master Agreement.  As of the
date of this Prospectus, QSI has paid the full amount of such exclusivity fee
arrearages and has not defaulted in the timely payment of any amounts that have
become due and payable under the other indebtedness.

         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.

         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
primary bases of competition for each product or potential product of the
Company are the cost of an active system and its system performance measured by
the level of noise or vibration attenuation compared to the cost and
performance of an alternative active or passive solution for the problem in
question.  At the present time passive solutions generally are less expensive
than active solutions, although passive solutions do not provide as great a
level of sound attenuation at the more harmful lower frequencies.  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, Toshiba Corp., Koss Corporation and Recoton, Inc.
among others.  To the Company's knowledge, each of such entities is pursuing
its own technology in active control systems, either on its own or in
collaboration with others, and has recently commenced attempts to exploit
commercially  such  technology.  The Company 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 attenuation field and other entities that
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.  In addition, the Company is aware that Andrea Electronics Corporation
is proceeding with the commercialization of in-wire noise cancellation with one
or more major providers of telephone services.  The Company also believes that
a number of major telecommunications and other electronics companies such as
AT&T Corporation, Texas Instruments Inc. and Motorola Inc. are or may be
developing in wire noise cancellation and electronic speech filtering
technologies similar to those being developed and commercialized by the
Company.  The Company is unable to determine at the present time what impact
such efforts might have on the Company's ability to successfully commercialize
its in-wire technology for use in telephones and other communications
applications.

         POSSIBLE NEED FOR ADDITIONAL FINANCING.  Historically, the Company
financed its operations through public and private placements of equity and
through the exercise of options and warrants granted to directors, employees
and others, as well as with license fees and research and development funding
from its strategic allies.  The cash raised from the April 1996 Private
Placement and the August 1996 Private Placement, the exercise of warrants and 
options including the options granted to the three institutional investors in
the April 1996 Private Placement, 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 reduced capital expenditures should be sufficient to sustain the
Company's anticipated future level of operations into 1997.  However, the
current available funds are not sufficient to sustain the Company for the next
twelve months.  The period during 1997 through which the Company can be
sustained is dependent upon the level of realization of funding from license
fees, royalties and product sales and engineering and development income and
the achievement of the operating cost savings from the events described above,
all of which are presently uncertain.




<PAGE>   17
         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.  In January 1996, the Company adopted a
plan that management believes should generate sufficient funds for the Company
to continue its operations into 1997.  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 referred to 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 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 in the April 1996
Private Placement.  The Company will monitor its performance against the plan
on a monthly basis and, if necessary, reduce its level of operations
accordingly.  The Company believes that the plan discussed above constitutes a
viable plan for the continuation of the Company's business into 1997.

         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.

         POSSIBLE PUBLIC SALES OF COMMON STOCK.  On October 6, 1992, the
Company adopted the 1992 Plan covering 6,000,000 shares of the Company's Common
Stock and providing for the grant of options to purchase Common Stock of the
Company and awards of restricted common stock to employees, officers and
directors of the Company. The 1992 Plan was approved by the stockholders at the
1993 Annual Meeting of Stockholders following which said 6,000,000 shares were
registered under the Securities Act.  An amendment to the 1992 Plan adopted by
the Option Committee on November 8, 1995, and approved by the stockholders at
the 1996 Annual Meeting of Stockholders (the "1996 Annual Meeting"), increased
the number of shares of Common Stock covered by the 1992 Plan to 10,000,000
shares and added active consultants to the Company as persons who are eligible
to participate under the 1992 Plan.  The Company has reserved 10,000,000 shares
of Common Stock for issuance upon the exercise of options granted under the
1992 Plan and for issuance upon the grant of restricted stock awards under the
1992 Plan. 6,000,000 of such shares are registered under the Securities Act,
and the Company also intends to register the      




<PAGE>   18
additional 4,000,000 shares covered by the 1992 Plan under an amendment to the
1992 Plan approved at the 1996 Annual Meeting.  As of August 23, 1996, the
Company has granted options to purchase 5,631,043 shares of Common Stock which
are currently exercisable and 65,000 shares of restricted stock under the 1992
Plan.

         On November 15, 1994, the Company adopted and on May 8, 1995 and
November 8, 1995 amended the Noise Cancellation Technologies, Inc. Option Plan
for Certain Directors (the "Directors Plan"), pursuant to which options to
purchase in the aggregate 821,000 shares of Common Stock were granted to two
directors of the Company.  The Directors Plan was approved by the stockholders
at the Company's 1995 Annual Meeting of Stockholders as to options to purchase
in the aggregate 725,000 shares of Common Stock.  An amendment to the Directors
Plan adopted by the Board of Directors on November 8, 1995, and approved by the
stockholders at the 1996 Annual Meeting, increased the number of shares of
Common Stock covered by the Plan to 821,000 shares and made certain  minor
changes concerning the Plan's administration.  The Company has reserved 821,000
shares of Common Stock for issuance upon the exercise of the options granted
under the Directors Plan and intends to register such 821,000 shares under the
Securities Act.  As of July 18, 1996, the Company has granted options to
purchase 821,000 shares of  Common Stock which are currently exercisable under
the Directors Plan.

         In the April 1996 Private Placement, the Company sold 1,000,000
shares, in the aggregate, of its Common Stock to three institutional investors.
Contemporaneously, the Company sold secured convertible term notes in the
aggregate principal amount of $1,200,000 to those institutional investors and
granted them each an option to purchase an aggregate of $3,450,000 of
additional shares of the Company's Common Stock. The per share conversion price
under the notes and the exercise price under the options are equal to the price
received by the Company for the sale of such 1,000,000 shares subject to
certain adjustments. On August 13, 1996 the Company issued 13,403,130 shares,
in the aggregate, of its Common Stock in connection with the three
institutional investors' exercise of their options and conversion of their
secured convertible term notes and on August 22, 1996 the Company issued
350,000 shares of its common stock to a financial consultant in partial
consideration for services rendered in connection with the April 1996 Private
Placement.  In conjunction with the April 1996 Private Placement, the Company 
also agreed to file a registration statement with the Commission covering the 
applicable shares and to use its best efforts to have such registration 
statement declared effective by the Commission as soon as practicable.  The 
Company also has reserved up to 1,596,870 shares of Common Stock for issuance 
in payment of amounts payable by the Company to said investors in the event 
such registration statement does not become effective on a timely basis.  The 
Company intends to register all of such shares under the Securities Act.

         As of August 23, 1996, the Company has reserved 6,006,710 shares of
Common Stock for issuance upon the exercise of warrants and options granted
outside the 1992 Plan, the Directors Plan and the April 1996 Private Placement
all of which the Company plans to register under the Securities Act to the
extent they are not now so registered.

         At August 23, 1996, the weighted average exercise price for all
currently exercisable and outstanding warrants and options was $0.7842.

         On November 14, 1995, the Company sold 4,800,000 shares of Common
Stock and on August 29, 1996, the Company sold 1,753,968 shares of Common Stock
in two private placements to a Canadian institutional investor pursuant to
Regulation S under the Securities Act.  The Company also issued 87,698 shares
of its Common Stock to a financial consultant in consideration for services
rendered in connection with the August 29, 1996 Private Placement.

         The possibility of the sale of the shares of Common Stock described in
the preceding six paragraphs, all of which the Company plans to register under
the Securities Act to the extent they are not now so registered or exempt from
the registration requirements of the Securities Act, may adversely
affect the market price of the Company's Common Stock.

         NASDAQ/NMS LISTING REQUIREMENTS; DISCLOSURE RELATING TO LOW-PRICED
STOCKS. The Company's Common Stock currently is quoted on the National
Association of Securities Dealers, Inc. Automated Quotation National Market
System ("NASDAQ/NMS").  The NASDAQ/NMS has adopted quantitative maintenance
criteria for continued listing by the NASDAQ/NMS under which a company is
required, among other things, to maintain net tangible assets of at least (i)
$2,000,000 if it has sustained losses from continuing operations and/or net
losses in two of its three most recent fiscal years or (ii) $4,000,000 if it
has sustained losses from continuing operations and/or net losses in three of
its four most recent fiscal years.  Failure of the Company to continue to meet
the maintenance requirements could result in the Common Stock losing its
NASDAQ/NMS designation.  The NASDAQ/NMS provides brokers and others with
immediate access to the best bid and asked prices and other information about




<PAGE>   19
the Common Stock during each trading day.  If the Company were to lose its
NASDAQ/NMS designation, real-time price information for the Common Stock might
cease to be available.  As a result, a stockholder might find it more difficult
to dispose of, or to obtain accurate quotations as to the price of, the Common
Stock.  In addition, if the Company were to lose the NASDAQ/NMS designation,
the Common Stock might no longer qualify as a "margin security" as defined by
the Federal Reserve Board.

         If the Company were to lose its NASDAQ/NMS designation and, at any
time following the loss of such designation, did not have either (i)  net
tangible assets in excess of $2,000,000 or (ii) average revenue of at least
$6,000,000 for the last three years, the Common Stock could become subject to
the Commission's "penny stock" rules.  The penny stock rules impose additional
sales practice requirements on broker-dealers who sell securities designated as
penny stocks to persons other than established customers and certain types of
accredited investors.  For transactions covered by the penny stock rules, the
broker-dealer must make a special suitability determination for the purchaser
and must have received the purchaser's written consent to the transaction prior
to the sale.  The rules require the delivery, prior to the transaction, of a
disclosure schedule prepared by the Commission relating to the penny stock
market.  The rules also require disclosure by the broker-dealer of commissions
payable to both the broker-dealer and the registered representative and current
quotations for the securities.  If the broker-dealer is the sole market-maker
for the penny stock, the broker-dealer must disclose this fact and the
broker-dealer's presumed control over the market.  Finally, monthly statements
must be sent disclosing recent price information for the penny stock held in
the customer's account and information on the limited market in penny stocks.
The additional burdens imposed upon broker-dealers by the penny stock rules may
discourage broker-dealers from effecting transactions in penny stocks.  Thus,
if the Common Stock were to fall within the definition of a penny stock, the
liquidity of the Common Stock could be reduced and there could be a material
effect on the trading market for the Common Stock.

         POSSIBLE VOLATILITY OF COMMON STOCK.  The market prices for securities
of emerging and high-technology companies have historically been highly
volatile.  Future announcements concerning the Company or its competitors could
have a significant impact on the market price of the Common Stock.

         BLANK CHECK PREFERRED STOCK.  The Board of Directors has total
discretion in the issuance and the determination of the rights and privileges
of any shares of Preferred Stock which might be issued in the future, which
rights and privileges may be detrimental to the holders of the Common Stock.
The Company is authorized to issue 10,000,000 shares of Preferred Stock none of
which has been designated to date.  The issuance of Preferred Stock in the
future could discourage or impede a tender offer, proxy contest or other
similar transaction involving a potential change in control of the Company,
which transaction might be viewed favorably by other shareholders.

                              SELLING STOCKHOLDERS

                 The following table sets forth certain information with
respect to the Selling Stockholders.  The Company will not receive any proceeds
from the sale of the shares by the Selling Stockholders.

                 Of the 10,000,000 shares of the Common Stock reserved for
issuance under the 1992 Plan, as of August 23, 1996, 3,588,686 shares are 
available for the grant of options to purchase shares of Common Stock and 
restricted Common Stock awards to be made in the Company's discretion
throughout the remainder of the term of the 1992 Plan which, unless terminated 
earlier in accordance with the terms of the 1992 Plan, will terminate on May
27, 2003.  Under the terms of the 1992 Plan grants may be made to one or more
of the Selling Stockholders or to other persons who may be deemed "Affiliates"
of the Company, as that term is defined under the Securities Act, in which
event the information set forth in the following table will be amended by a
supplement to this Prospectus.

ITEM 6.   INDEMNIFICATION OF OFFICERS AND DIRECTORS

Article IX of the Registrant's Certificate of Incorporation provides as
follows:

     (a)  Each person who was or is made a party or is threatened to be made a
party to or is involved in any action, suit or proceeding, whether civil,
criminal, administrative or investigative (hereinafter a "proceeding"), by
reason of the fact that he or she, or a person of whom he or she is the legal
representative, is or was a director or officer, of the Corporation or is or
was serving at the request of the Corporation as a director, officer, employee
or agent of another corporation or of a partnership, joint venture, trust or
other enterprise, including service with respect to employee benefit plans,
whether the basis of such proceeding is alleged action in an official capacity
as a director, officer, employee or agent or in any other capacity while
serving as a director, officer, employee or agent, shall be indemnified and
held harmless by the Corporation to the fullest extent authorized by the
Delaware General Corporation Law, as the same exists or may hereafter be
amended (but, in the case of any such amendment only to the extent that such
amendment permits the Corporation to provide broader indemnification rights
than said law permitted the Corporation to provide prior to such amendment),
against all expense, liability and loss (including attorneys' fees, judgments,
fines, ERISA excise taxes or penalties and amounts paid or to be paid in
settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of his or her heirs, executors and administrators; provided, however,
that, except as provided in paragraph (b) hereof, the Corporation shall
indemnify any such person seeking indemnification in connection with a
proceeding (or part thereof) initiated by such person only if such proceeding
(or part thereof) was authorized by the Board of Directors of the Corporation. 
The right to indemnification conferred in this Section shall be a contract
right and shall include the right to be paid by the Corporation the expenses
incurred in defending any such proceeding in advance of its final disposition;
provided, however, that, if the Delaware General Corporation Law requires, the
payment of such expenses incurred by a director or officer in his or her
capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such person while a director or officer,
including, without  limitation, service to an employee benefit plan) in
advance of the final disposition of a proceeding, shall be made only upon
delivery to the Corporation of an undertaking, by or on behalf of such
director or officer, to repay all amounts so advanced if it shall ultimately
be determined that such director or officer is not entitled to be indemnified
under this Section or otherwise.  The Corporation may, by action of its Board
of Directors, provide indemnification to employees and agents of the
Corporation with the same scope and effect as the foregoing indemnification of
directors and officers.

     (b)  If a claim under paragraph (a) of this Section is not paid in full
by the Corporation within thirty days after a written claim has been received
by the Corporation, the claimant may at any time thereafter bring suit against
the Corporation to recover the unpaid amount of the claim and, if successful
in whole or in part, the claimant shall be entitled to be paid also the
expense of prosecuting such claim.  It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final 








                                     II-2
<PAGE>   24
disposition where the required undertaking, if any is required, has been
tendered to the Corporation) that the claimant has not met the standards of
conduct which make it permissible under the Delaware General Corporation Law
for the Corporation to indemnify the claimant for the amount claimed, but the
burden of proving such defense shall be on the Corporation.  Neither the
failure of the Corporation (including its Board of Directors, independent
legal counsel, or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in the Delaware General Corporation Law, nor an actual determination
by the Corporation (including its Board of Directors, independent legal
counsel, or its stockholders) that the claimant has not met such applicable
standard or conduct, shall be a defense to the action or create a presumption
that the claimant has not met the applicable standard of conduct.

     (c)  The right to indemnification and the payment of expenses incurred in
defending a proceeding in advance of its final disposition conferred in this
Section shall not be exclusive of any right which any person may have or
hereafter acquire under any statute, provision of the Certificate of
Incorporation, by-law, agreement, vote of stockholders or disinterested
directors or otherwise.

     (d)  The Corporation may maintain insurance, at its expense, to protect
itself and any director, officer, employee or agent of the Corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any such expense, liability or loss, whether or not the Corporation
would have the power to indemnify such person against such expense, liability
or loss under the Delaware General Corporation Law.

ITEM 9.   UNDERTAKINGS (NUMBERED AS IN ITEM 512 OF REGULATION S-K)


     The undersigned registrant hereby undertakes:

     (a)(1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

             (i)    To include any prospectus required by section 10(a)(3) of
     the Securities Act of 1933;

             (ii)   To reflect in the prospectus any facts or event arising
     after the effective date of the registration statement (or the most
     recent post-effective amendment thereof) which, individually or in the
     aggregate, represent a fundamental change in the information set forth in
     the registration statement;

             (iii)  To include any material information with respect to the
     plan of distribution not previously disclosed in the registration
     statement or any material change to such information in the registration
     statement;

provided, however, that the undertakings set forth in paragraphs (1)(i) and
(1)(ii) above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed by the registrant pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in this registration
statement.

     (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination
of the offering.

     (b)  That for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in this registration statement shall be












                                     II-4
<PAGE>   26
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.

     (h)  That insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.


                                  SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, as amended,
the Registrant certifies that it has reasonable grounds to believe that it
meets all of the requirements for filing on Form S-8 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned,

                     NOISE CANCELLATION TECHNOLOGIES, INC.
                              STOCK INCENTIVE PLAN
                          (AS ADOPTED APRIL 14, 1993,
                      AND AMENDED THROUGH AUGUST 16, 1996)



         1.      PURPOSE.

                 The purpose of the Noise Cancellation Technologies, Inc. Stock
Incentive Plan (the "Plan") is to promote the interests of Noise Cancellation
Technologies, Inc. (the "Corporation") and its stockholders by:

                 (a)      affording its employees, members of the Board of
         Directors of the Corporation (the "Board") who are not employees of
         the Corporation or any subsidiary thereof ("Outside Directors") and
         active consultants to the Corporation an incentive by means of an
         opportunity to acquire Common Stock, par value $.01 per share, of the
         Corporation (the "Common Stock"), to remain associated with the
         Corporation and to exert their maximum efforts on its behalf.

                 (b)      recognizing the contributions and sacrifices made by
         its employees and certain Outside Directors by granting them options
         to acquire Common Stock and thereby affording them an opportunity to
         share in the increase in the value of the Common Stock and an
         incentive to remain associated with the Corporation and to exert their
         maximum efforts in its behalf; and

                 (c)      enhancing the Corporation's ability to attract and
         retain the services of experienced, able and knowledgeable persons to
         serve as directors and consultants and providing additional incentive
         for such directors and consultants to make a maximum





                                                                               1
<PAGE>   2
         contribution to the Corporation's success through continuing and
         increased share ownership in the Corporation.

         2.      ADMINISTRATION.

                 The Plan shall be administered by the Board  or, at the
discretion of the Board, a committee appointed by the Board consisting of at
least two (2) Directors and designated as either the Compensation Committee or
the Option Committee (the "Committee") of the Board.  As used in this Plan, the
term "Administrator" shall mean the Board, or, if the Board has appointed a
Committee to administer the Plan, the Committee, as the case may be.  In
addition to its duties with respect to the Plan stated elsewhere in the Plan,
the Administrator shall have full authority, consistent with the Plan, to
interpret the Plan,  to promulgate such rules and regulations with respect to
the Plan as it deems desirable and to make all other determinations necessary
or desirable for the administration of the Plan.  All decisions, determinations
and interpretations of the Administrator shall be binding upon all persons.

         3.      SHARES SUBJECT TO THE PLAN.

                 The aggregate number of shares of Common Stock which may be
covered by stock options (the "Options") and restricted shares (the "Restricted
Shares") granted pursuant to the Plan is 10,000,000 shares, subject to
adjustment under Section 11.  Shares which may be delivered on exercise or
settlement of Options or Restricted Shares may be previously issued shares
reacquired by the Corporation or authorized but unissued shares.  Restricted
Shares that





                                                                               2
<PAGE>   3
are forfeited and shares covered by Options that are forfeited, cancelled, or
that otherwise expire unexercised shall again be available for grant under the
Plan.

         4.      ELIGIBILITY.

         The Administrator shall from time to time in its discretion select the
employees and active consultants to whom Options and Restricted Shares shall be
granted (the "Participants") from among the employees and consultants of the
Corporation and its subsidiary corporations (the "Subsidiaries").  Except as
provided in the next sentence, Outside Directors of the Corporation are only
eligible for the Options and Restricted Shares described in Sections 8 and 10
below.  In addition, Options are hereby granted to the Participants and two (2)
Outside Directors listed on Schedule A attached hereto in the amounts set forth
after their respective names.

         5.      TERMS OF OPTIONS GRANTED TO PERSONS ON SCHEDULE A.

                 (a)      The Options are granted as of October 6, 1992, the
         effective date of the Plan and the date of the adoption of the Plan by
         the Option Committee (prior to amendment on April 14, 1993), subject
         to the provisions of Section 19 below.  Each Option shall be for the
         right to purchase one share of Common Stock.

                 (b)      Each Option shall be for a term of seven (7) years
         from the "First Exercise Date" as hereinafter defined.  The "First
         Exercise Date" shall be the later of:  (i) the date on which the Plan
         is approved by the Stockholders of the Corporation, or (ii) 180 days





                                                                               3
<PAGE>   4
         after the date on which the registration statement filed with the
         Securities and Exchange Commission (the "SEC") on August 31, 1992 is
         declared effective by the SEC.

                 (c)      The purchase price for each share of Common Stock
         subject to an Option shall be $2.375, the fair market value of the
         Common Stock on October 6, 1992, the date of the grant of Options.

                 (d)      Each Option shall become fully vested on the First
         Exercise Date.

         6.      TERMS OF CERTAIN OTHER OPTIONS.

                 The following terms apply to Options other than those Options
granted in accordance with Section 5 above to the Participants and two (2)
Outside Directors listed on Schedule A and other than those granted in
accordance with Section 8 below to Outside Directors.

                 (a)      The Administrator shall, in its discretion, determine
         the time or times when Options shall be granted and the number of
         shares of Common Stock to be subject to each Option.  The
         Administrator shall have the discretion to designate Options as
         incentive stock options, as defined in Section 422(b) of the Internal
         Revenue Code of 1986, as amended (the "Code").  In the case of
         incentive stock options, the aggregate fair market value (determined
         as of the date the Option is granted) of the stock for which Options
         may become exercisable by any Participant for the first time during
         any calendar year (under all stock option plans of the Corporation and
         its Subsidiaries) shall not exceed $100,000.  Options may be granted
         under the Plan on such terms and conditions as the Administrator
         considers appropriate, which may differ from those provided in the
         Plan,





                                                                               4
<PAGE>   5
         where such Options are granted in substitution for stock options held
         by employees of other companies who concurrently become employees of
         the Corporation or a Subsidiary as the result of a merger or
         consolidation of the employing company with, or the acquisition of the
         property or stock of the employing company by, the Corporation or a
         Subsidiary.

                 (b)      Except as provided in paragraph (d), each Option
         shall be for such term as the Administrator shall determine, but not
         more than ten (10) years from the date it is granted, except that the
         term of an Option, other than an incentive stock option, may extend up
         to eleven (11) years from the date the Option is granted if the
         Participant dies within the tenth year following the date of grant.

                 (c)      Except as provided in paragraph (a), the purchase
         price for each share of Common Stock subject to an Option shall be no
         less than the fair market value of the Common Stock on the date the
         Option is granted.

                 (d)      In the case of an incentive stock option, as defined
         in Section 422(b) of the Code, granted to a Participant who at the
         time of the Option is granted owns (within the meaning of Section
         422(b)(6) of the Code) stock possessing more than ten (10%) percent of
         the total combined voting power of all classes of stock of the
         corporation employing such Participant or of its parent corporation or
         a subsidiary corporation (as defined in Section 424(e) and 424(f),
         respectively, of the Code), the purchase price for each share of
         Common Stock subject to the Option shall be at least one hundred ten
         (110%) percent of the fair market value of the share at the time such
         Option is granted and such Option shall





                                                                               5
<PAGE>   6
         not be exercisable after the expiration of five (5) years from the
         date such Option is granted.

                 (e)      In the case of incentive stock options, the
         instrument evidencing such Options shall provide that if, within two
         (2) years from the date of grant of the Option or within one (1) year
         after the transfer of shares of Common Stock to the Participant on
         exercise of the Option, the Participant makes disposition (as defined
         in Section 424(c) of the Code) of any shares of such Common Stock, the
         Participant shall notify the Corporation of such disposition in the
         manner and within the time as the Administrator in its discretion
         shall determine.  The Administrator may direct that a legend
         restricting transfer in the absence of appropriate notification be
         affixed to any stock certificates representing Common Stock
         transferred under the Plan.

         7.      TERMS APPLICABLE TO ALL OPTIONS.

                 (a)      Exercise of an Option shall be by written notice in
         the form and manner determined by the Administrator.  The
         Administrator may in its discretion (i) determine installment exercise
         terms for an Option under which it may be exercised in a series of
         cumulative installments; (ii) prescribe rules limiting the frequency
         of exercise of Options or the minimum number of shares that may be
         exercised at any one time; (iii) determine the form of consideration
         (including cash, shares of Common Stock valued at fair market value as
         of the date of exercise, or any combination of cash and shares of
         Common Stock) which may be accepted in payment of the purchase price
         of shares purchased pursuant to





                                                                               6
<PAGE>   7
         the exercise of an Option; and (iv) prescribe such other rules or
         conditions as it considers appropriate regarding the exercise of
         Options granted under the Plan.

                 (b)      Each Option shall be evidenced by a written
         instrument which shall state such terms and conditions which are not
         inconsistent with the provisions of the Plan as the Administrator in
         its sole discretion shall determine and approve, including terms and
         conditions regarding the exercise of Options upon termination of
         employment or service.

                 (c)      The Administrator may, in its discretion, make loans
         available to Participants and Outside Directors, on reasonable terms,
         with funds to be provided by the Corporation, to facilitate payment by
         any Participant or Outside Director of the exercise price of, or any
         tax withholding obligation incurred with respect to any Options
         granted under the Plan.  The Administrator or the Corporation may, in
         their respective discretion, take other steps to enable the
         Corporation to facilitate the payment of such exercise price or tax
         withholding obligations, including but not limited to arranging for
         the provisions of loans by, or other arrangements with, third parties,
         including but not limited to banks or brokers, with or without a
         guarantee of such loans by the Corporation.

         8.      OUTSIDE DIRECTORS' OPTIONS.

                 Effective the date of an Outside Director's initial  election
the Board of Directors, each Outside Director shall automatically be granted
Options to purchase 75,000 shares of Common Stock.  All such Options shall be
nonstatutory stock options.  The purchase price of the Options shall be the
fair market value of the Common Stock on the date the Options are granted.





                                                                               7
<PAGE>   8
                 Except as set forth below, one-third (1/3) of the total number
of shares subject to Options granted to an Outside Director shall become
exercisable on the date of grant, one-third (1/3) on the first anniversary of
the date of grant and one-third (1/3) on the second anniversary of the date of
grant.  The right to purchase shares with respect to Options which have become
exercisable shall be cumulative during the term of the Options.  All of such
75,000 Options granted to an Outside Director shall immediately become
exercisable in the event of a Change of Control, as defined in Section 12
below.  The Options may be exercised by an Outside Director during the period
that an Outside Director remains a member of the Board and for a period of
thirty-six (36) months following retirement, provided that only those Options
exercisable at the date of an Outside Director's retirement may be exercised
during the period following retirement; and, provided further, that in no event
shall the Option be exercisable more than ten (10) years after the date of
grant.  In the event of the death of an Outside Director, his or her Options
shall be exercisable only within the twelve (12) months next succeeding the
date of death, and then only (i) by the executor or administrator of the
Outside Director's estate or by the person or persons to whom the Outside
Director's rights under the Options shall pass by the Outside Director's will
or the laws of descent and distribution, and (ii) if an to the extent that the
Outside Director was entitled to exercise the Options at the date of the
Outside Director's death, provided that in no event shall the Options be
exercisable more than ten (10) years after the date of grant.  Options granted
to an Outside Director shall be exercisable only upon payment to the
Corporation of the purchase price of the Options.  Payment for the shares shall
be in United States dollars, payable in cash, by check, in whole shares of
Common Stock, or in a combination





                                                                               8
<PAGE>   9
of whole shares of Common Stock and cash, having an aggregate fair market value
equal to the purchase price of the Options.

         9.      RESTRICTED SHARES.

                 (a)      The Administrator may from time to time, and subject
         to the provisions of the Plan and such other terms and conditions as
         the Administrator may determine, grant restricted shares to
         Participants under the Plan.  Each grant of Restricted Shares shall be
         evidenced by a written instrument which shall state the number of
         Restricted Shares covered by the grant and the terms and conditions
         which the Administrator shall have determined with respect to such
         grant.

                 (b)      A stock certificate representing the Restricted
         Shares granted to a Participant shall be registered in the
         Participant's name but shall be held in custody by the  Corporation
         for the Participant's account.  The Participant generally shall have
         the rights and privileges of a stockholder as to such Restricted
         Shares, including the right to vote or otherwise act as a stockholder
         with respect to such Restricted Shares, except that the following
         restrictions shall apply:  (i) the Participant shall not be entitled
         to delivery of the certificate until the expiration or termination of
         the Restriction Period (as defined in paragraph (d) below) and the
         satisfaction of any other conditions prescribed by the Administrator;
         (ii) none of the Restricted Shares may be sold, transferred, assigned,
         pledged, or otherwise encumbered or disposed of prior to termination
         of the Restriction Period; and (iii) the Participant shall forfeit and
         immediately transfer back to the Corporation without payment all of
         the Restricted Shares, and all rights of the Participant





                                                                               9
<PAGE>   10
         to such Restricted Shares shall terminate without further obligation
         on the part of the Corporation, if and when the Participant cases to
         be an employee of the Corporation or any of its Subsidiaries prior to
         expiration or termination of the Restriction Period and the
         satisfaction of any other conditions prescribed by the Administrator
         applicable to such Restricted Shares.  Cash dividends, if any, with
         respect to the Restricted Shares shall be paid to the Participant.

                 (c)      Upon the expiration or termination of the Restriction
         Period and the satisfaction of any other conditions prescribed by the
         Administrator, the restrictions applicable to the Restricted Shares
         shall lapse and a stock certificate for the number of Restricted
         Shares with respect to which the restrictions have lapsed shall be
         delivered, free of all such restrictions, to the Participant or the
         Participant's beneficiary or estate, as the case may be. The
         Corporation shall not be required to deliver any fractional share of
         Common Stock, but will pay, in lieu thereof, the fair market value
         (determined as of the date the restrictions lapse) of such fractional
         shares to the Participant or the Participant's beneficiary or estate,
         as the case may be.  No payment will be required from the Participant
         upon the issuance or delivery of any Restricted Shares, except that
         any amount necessary to satisfy applicable federal, state or local tax
         requirements shall be withheld or paid promptly upon notification of
         the amount due and prior to or concurrently with the issuance or
         delivery of a certificate representing such shares.

                 (d)      Vesting of each grant of Restricted Shares shall
         require employee Participants to remain in the employment of the
         Corporation or a Subsidiary for a prescribed period (the "Restriction
         Period") subject to acceleration upon the occurrence





                                                                              10
<PAGE>   11
         of certain events, as the Administrator may determine and specify in
         the written instrument evidencing such grant.  The Administrator shall
         determine the Restrictions Period or Periods which shall apply to the
         shares of Common Stock covered by each grant of Restricted Shares,
         provided that in no case shall the Restriction Period be less than one
         (1) year.

         10.     OUTSIDE DIRECTORS' RESTRICTED SHARES.

                 Each Outside Director shall be granted 5,000 Restricted Shares
on the date of his or her initial election to the Board of Directors.  In
addition, 5,000 Restricted Shares shall be granted to each Outside Director
elected at the Corporation's Annual Meeting of Stockholders (the "Annual
Meeting") on the date of the Annual Meeting in each calendar year after the
calendar year in which the Outside Director was initially elected to the Board
of Directors.  Each such grant of Restricted Shares shall be evidenced by a
written instrument which shall state the number of Restricted Shares covered by
the grant and the other terms and conditions which shall apply to such grant as
provided under the Plan.  In this regard, the provisions of paragraphs (b) and
(c) of Section 9 above shall apply to the grants of Restricted Shares to
Outside Directors hereunder except that the Restriction Period shall be three
(3) years for all such Restricted Shares and the forfeiture described in clause
(iii) of said paragraph (b) shall not apply thereto.

         11.     ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

                 If there is a change in the number or kind of outstanding
shares of the Corporation's stock by reason of a stock dividend, stock split,
recapitalization, merger,





                                                                              11
<PAGE>   12
consolidation, combination or other similar event, or if there is a
distribution to stockholders of the Corporation's Common Stock other than a
cash dividend, appropriate adjustments shall be made by the Administrator to
the number and kind of shares subject to the Plan; the number and kind of
shares under Options and Restricted Shares then outstanding; the maximum number
of shares available for Options and Restricted Shares; the purchase price for
shares of Common Stock covered by Options; and other relevant provisions, to
the extent that the Administrator, in its sole discretion, determines that such
changes make such adjustments necessary to be equitable.  Similar adjustment
may also be made by the Administrator in its discretion if substitute Options
are granted pursuant to Section 6(a).

         12.     CHANGE IN CONTROL.

                 Upon the occurrence of a Change in Control, all Options and
Restricted Shares held by the Participants shall immediately become vested and
exercisable unless the terms of the written instrument evidencing their grant
specifically provides otherwise and all Options and Restricted Shares held by
Outside Directors shall immediately become vested and exercisable,
notwithstanding the provisions of Sections 8 and 10 above to the contrary.  A
"Change in Control" shall be deemed to have occurred if:  (i) any "person" (as
such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than
a trustee or other fiduciary holding securities under an employee benefit plan
of the Corporation or a corporation owned directly or indirectly by the
stockholders of the Corporation in substantially the same  proportions as their
ownership of stock of the Corporation, is or becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of
the Corporation representing twenty (20%)





                                                                              12
<PAGE>   13
percent or more of the total voting power represented by the Corporation's then
outstanding voting securities; or (ii) during any period of two (2) consecutive
years, individuals who at the beginning of such period constitute the Board of
Directors of the Corporation and any new director whose election by the Board
of Directors or nomination for election by the Corporation's stockholders was
approved by a vote of at least two-thirds (2/3) of the directors then still in
office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for any
reason to constitute a majority thereof; or (iii) the stockholders of the
Corporation approve a merger or consolidation of the Corporation with any other
corporation, other than a merger or consolidation which would result in the
voting securities of the Corporation outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) at least eighty (80%) percent
of the total voting power represented by the voting securities of the
Corporation or such surviving entity outstanding immediately after such merger
or consolidation, or the stockholders of the Corporation approve a plan of
complete liquidation of the Corporation or an arrangement for the sale or
disposition by the Corporation of all or substantially all of the Corporation's
assets.





                                                                              13
<PAGE>   14
         13.     TERMINATION OF EMPLOYMENT OR SERVICES.

                 The written instrument evidencing the grant of Options or
Restricted Shares shall contain such provisions as the Administrator may
determine concerning rights, limitations and forfeitures that may apply in the
event of the termination of the employment of a Participant other than a
Participant who has been granted Options under Section 4 above and is listed on
Schedule A.  The following paragraphs of this Section 13 apply to the
termination of the employment or services of the Participants and Outside
Directors with respect to Options under Section 4 above.

                 (a)      Termination by Reason of Death or Disability.  In the
         event the employment of a Participant or service of an Outside
         Director is terminated by reason of death or disability, any
         outstanding Options granted to such Participant or Outside Director
         shall vest as of the date of termination of employment or service and
         may be exercised, if at all, no more than one (1) year following
         termination of employment or service, unless the Options, by their
         terms, expire earlier or such longer period after such termination
         ending not later than the date the Option, by their terms, expire as
         may be determined by the Option Committee.

                 (b)      Termination by Retirement.  In the event the
         employment of a Participant or service of an Outside Director is
         terminated by reason of Retirement, any outstanding Options granted to
         such Participant or Outside Director which are vested as of the date
         of termination of employment or service may be exercised, if at all,
         no more than three (3) years following termination of employment or
         service, unless the Options, by their terms, expire earlier or such
         longer period after such termination ending not later than the date





                                                                              14
<PAGE>   15
         the Option, by their terms, expire as may be determined by the Option
         Committee.  For the purpose of this paragraph (b), and until such time
         as the Corporation establishes a retirement program, the criteria for
         Retirement are defined as a Participant or Outside Director whose age
         in years on the date of Retirement when added to the number of years
         of continuous service with the Corporation and its subsidiaries
         immediately preceding such date equals a number greater than fifty-one
         (51), provided the number of such years of service is not less than
         five (5).  Exceptions to these criteria may be made by action of the
         Board of Directors.

                 (c)      Termination of Employment for Other Reasons.  If the
         employment of a Participant or service of an Outside Director shall
         terminate for any reason other than the reasons set forth in (a) or
         (b) above, and other than for cause, all outstanding Options granted
         to a Participant which are vested as of the date of termination of
         employment or service may be exercised by such Participant or Outside
         Director within the period beginning on the effective date of
         termination of employment or service and ending three (3) months after
         such date, unless the Options, by their terms, expire earlier or
         within such longer period after such  termination ending not later
         than the date the Option, by their terms, expire as may be determined
         by the Option Committee.

                 (d)      Termination for Cause.  If the employment or service
         of a Participant or Outside Director shall terminate for cause, all
         outstanding Options held by such Participant or Outside Director shall
         immediately terminate and be forfeited to the Corporation, and no
         additional exercise period shall be allowed.





                                                                              15
<PAGE>   16
                 (e)      Options Not Vested at Termination.  Any outstanding
         Options not vested as of the effective date of termination of
         employment or service shall expire immediately and shall be forfeited
         to the Corporation.

         14.     TRANSFERABILITY OF OPTIONS.

                 Options shall be non-assignable and non-transferable by the
Participants and Outside Directors other than by will or the laws of descent
and distribution, and shall be exercisable during a Participant's or Outside
Director's lifetime only by the Participant or Outside Director or his or her
agent, attorney-in-fact, or guardian.

         15.     LAWS AND REGULATIONS.

                 The Plan, the grant and exercise of Options, the grant of
Restricted Shares and the obligations of the Corporation to sell or deliver
shares of Common Stock under the Plan shall be subject to all applicable laws,
regulations and rules.

         16.     NO EMPLOYMENT RIGHTS.

                 Nothing in the Plan shall confer upon any employee of the
Corporation or any Subsidiary of the Corporation any right to continued
employment, or interfere with the right of the Corporation or a Subsidiary to
terminate his or her employment at any time.





                                                                              16
<PAGE>   17
         17.     TAX WITHHOLDING.

                 Any payment to or settlement with a Participant or Outside
Director in cash, or in Common Stock, pursuant to any provision of the Plan
shall be subject to withholding of income tax, FICA tax or other taxes to the
extent the Corporation is required to make such withholding.  Any required
withholding payable by a Participant or Outside Director with respect to any
tax may be paid in whole shares of Common Stock or in a combination of whole
shares of Common Stock and cash, having an aggregate fair market value equal to
the amount of any required withholding obligation.

         18.     TERMINATION; AMENDMENTS.

                 (a)      The Administrator may at any time terminate the Plan.
         Unless the Plan shall previously have been terminated by the
         Administrator, it shall terminate on the tenth  anniversary of the
         First Exercise Date.  No Option or Restricted Share may be granted
         after such termination.

                 (b)      The Administrator may at any time or times amend the
         Plan or amend any outstanding Options or Restricted Shares for the
         purpose of satisfying the requirements of any changes in applicable
         laws or regulations or for any other purpose which at the time may be
         permitted by law, provided that no amendment of any outstanding Option
         or Restricted Share shall contain terms or conditions inconsistent
         with the provisions of the Plan as determined by the Administrator.





                                                                              17
<PAGE>   18
                 (c)      Except as provided in Section 11, no such amendment
         shall, without the approval of the stockholders of the Corporation:
         (i) increase the maximum number of shares of Common Stock for which
         Options and Restricted Shares may be granted under the Plan; (ii)
         except to the extent required or permitted under Section 6(a) in the
         case of substitute Options, reduce the price at which Options may be
         granted below the price provided for in Section 6(c); (iii) reduce the
         Option Price of outstanding Options; (iv) extend the period during
         which Options or Restricted Shares may be granted; (v) except to the
         extent permitted or required under Section 6(a) in the case of
         substitute Options, extend the period during which an outstanding
         Option may be exercised beyond the maximum period provided for in
         Section 6(b); (vi) materially increase in any other way the benefits
         accruing to Participants; (vii) change the class of persons eligible
         to be Participants; or (viii) preclude a member of the Option
         Committee as acting as a "disinterested administrator" (as defined for
         the purpose of Rule 16b-3, or any successor rule under the Exchange
         Act) of the Plan or any other stock-based employee benefit plan of the
         Corporation.

                 (d)      The provisions of Sections 8 and 10 may not be
         amended more than once every six (6) months, other than to comport
         with changes in the Internal Revenue Code, the Employee Retirement
         Income Security Act, or rules thereunder.

         19.     EFFECTIVE DATE.

                 The Plan shall become effective upon approval by the Option
Committee; provided, however, that the Plan shall be submitted to the Board and
to the stockholders for





                                                                              18
<PAGE>   19
approval, and if not approved by the stockholders within one year from the date
of approval by the Board shall be of no force and effect.  Options and
Restricted Shares granted by the Option Committee before approval of the Plan
by the stockholders shall be granted subject to such approval and shall not be
exercisable or payable before such approval.  Options and Restricted Shares may
be granted by the Administrator, or other actions may be taken under or with
respect to the Plan, pursuant to any Plan amendment that is subject to
stockholder approval, prior to the receipt of such stockholder approval,
provided that such Options and Restricted Shares shall not be exercisable or
payable before such approval.

         20.     SUCCESSORS.

                 All obligations of the Corporation under the Plan shall be
binding on any successor to the Corporation, whether the existence of such
successor is the result of a direct or indirect purchase, merger,
consolidation, or otherwise of all or substantially all of the business and/or
assets of the Corporation.

         21.     GOVERNING LAW.

                 The Plan, and any and all agreements hereunder, shall be
construed in accordance with and governed by the laws of the State of New York
and the United States of America.

Footnotes:
(1)      All persons who formerly held stock appreciation rights under the
         Company's stock appreciation rights program (and who lost such stock
         appreciation rights upon the cancellation and termination of that plan
         effective January 1, 1992) were granted one option for every stock
         appreciation right forfeited.
(2)      Certain non-executive officer employees of the Company were granted
         stock options, in lieu of forfeited stock appreciation rights, in
         April and June of 1992 at an exercise price of $5.09 per share.  These
         non-executive officer employees have the right to exchange all (but
         not part) of those $5.09 options for new options under the Plan on the
         basis of one new option for every two $5.09 options owned.
(3)      Those persons forfeiting options in connection with the completion of
         the private placement were granted new options under the Plan equal to
         the number of options forfeited by such person multiplied by a
         multiplier the numerator of which is the market price of the Company's
         common stock on October 6, 1992 (2.375), and the denominator of which
         is the exercise price applicable to the options forfeited by the
         person in question.
(4)      All grants were made October 6, 1992, at an exercise price of $2.375,
         the fair market value of the Company's common stock on that date.
