                                                PROSPECTUS



                                      TOP SOURCE TECHNOLOGIES, INC.
                                     1,085,937 Shares of Common Stock

         This Prospectus  relates to an aggregate of 1,085,937  shares of common
stock,  $.001  par  value  per  share  (the  "Common  Stock"),   of  Top  Source
Technologies,   Inc.  (the   "Company")   being  offered  for  sale  by  certain
stockholders  and  warrantholders  of the Company (the "Selling  Stockholders").
These shares  consist of 737,554 shares  acquired in connection  with the recent
conversion  of the  outstanding  5% Series A  Convertible  Preferred  Stock (the
"Series A  Preferred"),  and 348,383  shares  issuable  upon the exercise of two
classes of warrants (the  "Warrants").  Of the  Warrants,  100,000 are currently
exercisable  at $1.10 per share and 248,383  are  exercisable  at  approximately
$1.78 per share.  In May 1998, the Company sold to two foreign  purchasers  (the
"Purchasers"),  which are two of the Selling Stockholders, an aggregate of 1,000
shares of Series A Preferred for $1,000,000 (all of which has been redeemed) and
issued  Warrants  to  purchase  250,000  shares of the  Company's  Common  Stock
(100,000  of which are  currently  exercisable)  exercisable  at $1.10 per share
("Class A Warrants") to the Purchasers and three other  corporations  designated
by  Intercontinental  Holding  Company,  Ltd., the Placement  Agent. In December
1998, the Company and the Purchasers  modified the Series A Preferred  resulting
in  the  Company   issuing  an  additional   25,000   Warrants   exercisable  at
approximately $.89 per share (the "Class B Warrants").  The Company restructured
its  outstanding  $3,020,000  9%  Convertible  Notes (the "Notes") and issued to
certain  noteholders  Warrants to purchase shares of the Company's  Common Stock
exercisable at approximately $1.78 which price is $1.00 above market on the date
of the agreement ("Class C Warrants").  See "Recent Developments".  The Series A
Preferred  and  Warrants  were  issued  to  accredited   investors  pursuant  to
exemptions  from  registration  under Section 4(2) of the Securities Act of 1933
(the  "Securities  Act") and Rule 506  thereunder.  The Company was  required to
register the underlying  shares of Common Stock.  See  "Description  of Series B
Preferred and Warrants".

         As of the date of this Prospectus, the Company's officers and directors
beneficially own  approximately  2.3% of the Company's Common Stock.  Based upon
information  available to the Company, the only stockholder  beneficially owning
5% or more of the  Company's  Common Stock is a registered  investment  advisor.
According  to a Schedule  13-G filed by the  investment  advisor on  February 4,
1999,  as the result of investment  power over the accounts of its clients,  the
advisor and its affiliates  are the beneficial  owners of 5.85% of the Company's
Common  Stock,  none of  which  are  being  offered  for sale  pursuant  to this
Prospectus.  On May 11, 1999,  the closing price of the  Company's  stock on the
American Stock Exchange was approximately $1.25.

       All of the shares of Common Stock are offered for the respective accounts
of the  Selling  Stockholders  as  listed  in  this  Prospectus  under  "Selling
Stockholders".  The Company will  receive none of the proceeds  from the sale of
the shares of Common  Stock by the Selling  Stockholders.  However,  the Company
will receive a maximum of approximately $739,622 in connection with the exercise
of the  523,383  Warrants,  the  underlying  shares of which are covered by this
Prospectus.  Such proceeds will be used for general corporate  purposes.  All of
the  expenses  of this  offering,  estimated  at  $32,000  will be  borne by the
Company.

         The  Company  has been  advised by the  Selling  Stockholders  that the
Common  Stock may be  offered  and sold from time to time by or on behalf of the
Selling  Stockholders,  in or through  transactions or distributions  (including
crosses  and  block  transactions)  on the  American  Stock  Exchange  or in the
over-the-counter  market at market prices  prevailing at the time of sale, or at
negotiated  prices,  and in  connection  therewith  commissions  may be  paid to
brokers.  Brokers  participating in such  transactions may act as agents for the
Selling Stockholders. The Selling Stockholders, and any brokers participating in
this  offering  may be deemed to be  "underwriters"  within  the  meaning of the
Securities Act of 1933 (the "Securities  Act"), and any commissions  received by
them may be deemed to be underwriting compensation.


THE SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK. SEE "RISK FACTORS".






THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION OR
ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE  ACCURACY OR ADEQUACY OF THIS
PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

cautioned not to place undue reliance on these forward-looking statements, which
speak  only  as of the  date  of this  Prospectus.  Some  or all of the  results
anticipated  by these  forward-looking  statements  may not  occur  since  these
statements  are  subject  to risks and  uncertainties  that could  cause  actual
results to differ  materially from those  contemplated  in such  forward-looking
statements.  Such risks and uncertainties include those identified in this "Risk
Factors" section as well as the following:  the ability of the proposed buyer of
TSA to close the  necessary  financing;  potential  changes by  Chrysler  in the
placement of its speakers in Jeep(TM)  Wranglers or decline in production levels
at Chrysler  for  vehicles  installing  OHSS;  the  Company's  ability to market
OSA-IIs;  the acceptance of the OSA-II technology by the marketplace;  a general
tendency of large  corporations  not to change from known technology to emerging
new technology; the reliability of the OSA-II technology over an extended period
of time;  the Company's  ability to attract  additional  strategic  partners for
OSA-II and for TSA if the Company is unable to sell it; and other  matters which
may increase the Company's current losses.

         Historical  Losses.  Since  inception,  the Company has never  reported
income  from  operations.  As of March 31,  1999,  the  Company  had a  retained
earnings  deficit of  $29,136,868.  The Company has provided cash to support its
operations  from the income  generated  by TSA,  the  recent  sale of 20% of TSA
common stock, the sale of the assets of United Testing Group,  Inc. in 1996, the
sale of  securities  pursuant to private  placements  and the  exercise of stock
options  and  warrants  and  from  borrowings  from  institutional  lenders.  As
described below, TSA has lost and is losing  substantial  revenues from Chrysler
and the Company has entered into the  Agreement to sell TSA. The  management  of
the Company has serious concerns  concerning the ability of NCT Audio, Inc. (the
"Proposed Buyer") to close the Proposed  Transaction.  See "- Change in Business
of the Company - Loss of Operating Income" and " Failure of Proposed Transaction
to Close;  Substantial  Doubt that the Proposed  Transaction  Will  Close",  and
"Recent  Developments - Sale of TSA". TSA will remain profitable in spite of its
loss of revenues  from  Chrysler,  unless  Chrysler  discontinues  or materially
reduces its business  relationship  with the Company beyond that described below
in the risk factor  entitled " Dependence on Chrysler".  The Company has shifted
its  primary  focus  toward the sale of its OSA-II  which the  Company  has just
completed  developing.  However, the Company has generated only limited revenues
from the sale and lease of first  generation  on-site oil analyzers  ("OSA-Is").
Revenue  for TSI for the  year  ended  September  30,  1998  was  $392,653.  The
identifiable   assets  relating  to  the  oil  analysis  services  segment  were
approximately  $3,944,000,  which  includes  the net  value  of the  capitalized
database of $2,073,000 at September 30, 1998. In order to achieve profitability,
for which no assurances can be given, the Company is relying upon its ability to
market and sell OSA-IIs in sufficient  numbers to pay the Company's  substantial
fixed and other expenses.  The Company believes that its marketing  efforts will
be  successful.  However,  if the Company is unable to meet its goals or to have
the  necessary  resources to sustain its  marketing  activities  it could have a
material  adverse  effect on the Company's  business,  the carrying value of the
above listed  assets,  and the financial  condition of the Company.  The Company
will  continue to evaluate the success of the new  marketing  efforts as well as
the carrying value of the related  assets.  There can be no assurances  that the
Company will be profitable from operations in the future.

         Reliance on On-Site Oil Analyzer.  For several  years,  the Company has
concentrated  on sale and  marketing of its first  generation  OSA but with only
limited  success.  Since June 1997,  under the  direction of the  Company's  new
president,  the number of OSA-Is (and OSA-IIs) used by customers has  increased.
Additionally, the Company augmented its technical expertise by the hiring of Dr.
John Coates who has developed the  second-generation  machine OSA-II. The OSA-II
is substantially smaller, quicker and less expensive than the OSA. Moreover, the
OSA-II  does not  require  the  Company to rely upon an outside  corporation  to
manufacture  or assemble the  machines.  Because the Company is relying upon one
product, there is a substantially increased degree of risk to investors.

         Development of OSA-II. The Company completed the development of the new
OSA-II and in August 1998  completed the assembly of and shipped the first seven
OSA-IIs. However, as with the development of any new product,  unforeseen delays
occur and  problems  may be  discovered.  Sophisticated  computer  software  and
complex machines often encounter developmental difficulties or "bugs" which only
become  apparent  subsequent to widespread  commercial  use.  Problems which may
arise in the operation of the OSA-IIs could have a material  adverse effect upon
the Company's future operations.

         Inability  to Market  OSA-IIs.  The  Company  has  devoted  substantial
resources and different approaches to marketing the OSA-Is and OSA-IIs. Although
the  Company's  marketing  efforts  over  approximately  the last 24 months have
increased the number of OSA-Is being used, the Company has only received  orders
for tests or leases of multiple machines from six companies. Without the receipt
of  numerous  orders  for  multiple  OSA-IIs  and the  generation  of revenue by
end-users  it is not likely  that the  Company  can  profitably  market and sell
OSA-IIs.

         Dependence on Chrysler.  Historically,  the Company has derived  almost
all of its revenues from the sale of OHSS to Chrysler by TSA. In 1997,  Chrysler
discontinued using the OHSS on its Jeep(R) Cherokee vehicles.  In November 1998,
Chrysler  discontinued  producing its Jeep(R) Grand Cherokee Ltd. Plus, which is
the only model that installed the OHSS on an OEM basis.  TSA expects to continue
assembling the OHSS for the Jeep(R)  Wrangler  through at least model year 2002.
There can be no assurances  that Chrysler will continue to order OHSSs from TSA.
If Chrysler  discontinues  using the OHSS on the Jeep  Wrangler and the Proposed
Transaction is not consummated,  it will have a material adverse effect upon the
Company at least until the Company generates significant revenues from OSA-II.

         Change  in  Business  of  the  Company  -  Loss  of  Operating  Income.
Substantial  doubt exists as to whether the Proposed Buyer will be able to close
the Proposed  Transaction.  However,  the sale of TSA Assets, if it occurs, will
result in a major change in the nature of the Company's business. For the fiscal
years  ended  September  30,  1997  and  1998,  TSA  reported   $16,580,270  and
$10,815,205,   respectively,  in  revenue  or  approximately  97.6%  and  96.5%,
respectively,  of the Company's  consolidated  revenue.  TSA's operating income,
including the corporate  overhead  allocation  was $3,091,161 and $1,071,657 for
such  periods;  the  Company  reported  operating  losses  of  $(3,304,057)  and
$(5,529,562)   for  such  periods.   Assuming   consummation   of  the  Proposed
Transaction, the Company's sole remaining operating subsidiary will be TSI which
reported  approximately  $403,853  and  $392,653  of revenues in the years ended
September 30, 1997 and 1998, respectively.  Because TSA has been profitable, the
Company has utilized those profits to develop the OSA and OSA-II and to meet the
Company's other working capital needs including corporate overhead. To date, the
Company has only sold five  OSA-Is and 113 OSA-IIs and has not entered  into any
long-term leases of OSA-Is or OSA-IIs.  While  management  believes the proceeds
from the sale of  Assets,  if it  occurs,  will  permit  the  Company to pay its
indebtedness  and provide  working capital to meet current  operating  losses of
TSI,  the loss of TSA income  will  eliminate  future  contributions  to working
capital and could adversely affect the Company's long-term financial  condition.
The  Company  will be  required to meet its future  working  capital  needs from
additional  financing,  while the Company is currently  engaged in discussion to
re-finance its credit line and obtain new equity or debt financing. There can be
no assurances that the Company will obtain the necessary financing.

     Liquidity Considerations.  Because of its history of losses, the Company at
times  experiences  periods where it has liquidity  concerns.  Most recently the
Company  faced such a period prior to its December  1998 sale of  $3,500,000  of
Series B Preferred  Stock  ("Series B  Preferred")  as described  under  "Recent
Developments - Changes in Capitalization." Unless and until the Company develops
a profitable  business model, it will require  additional  financing in order to
meet its  working  capital  needs.  Any equity  financing  will be  dilutive  to
stockholders if such financing can be obtained.  The Company  anticipates it has
sufficient  working capital to last through  September,1999 if the TSA sale does
not close. The Company is engaged in discussions concerning a new debt or equity
financing.  The Company  believes that it can complete a financing if necessary,
which will  provide it with  sufficient  liquidity  for at least 12 months.  The
Company is uncertain as to the  ultimate  terms it can reach with any  potential
investors.  There  can be no  assurances  that  the  Company  can  complete  any
financing and meet its working capital needs.

         Potential  Impact of Conversion of Preferred  Stock.  On March 31, 1999
the holder of the  outstanding  $350,000  of the  Company's  Series A  Preferred
converted the Series A Preferred  into Common Stock at $1.00 per share,  or into
350,000  shares.  The holder  agreed to restrict  public  sale of these  350,000
shares of Common Stock until October 1, 1999 and  thereafter  only 70,000 shares
may be sold in each month.  The Series B Preferred  converts at a floating  rate
but  not  until  November  1,  1999.  The  Company  does  not  intend  to file a
registration  statement for the sale of the Common Stock underlying the Series B
Preferred until November 30, 1999. Commencing in December 1999, the Common Stock
issuable  upon  conversion  of the Series B Preferred may begin to be sold under
Rule 144.  The  beneficial  owner of the Series B Preferred is a director of the
Company.  The  following  impact  may  result  from the  conversion  of Series B
Preferred:

               The lower the price of the Common Stock,  the more shares will be
              issued upon conversion of the Series B.

               Conversion and sale of some shares increases the supply available
              for sale, which could further depress the market price. This could
              have an  escalating  effect and result in a further  depression of
              the price of the Common Stock.

               The  significant  downward  pressure  on the price of the  Common
              Stock could encourage  short sales by the selling  stockholders or
              others,  which  would  further  depress  the market  price for the
              Common Stock.

               The   conversion   of  the  Series  B  Preferred  may  result  in
              substantial  dilution to existing  stockholders  since the holders
              may  ultimately  convert  their shares into a very large number of
              shares of Common Stock if such Common Stock trades at lower prices
              at the times of conversion.
See "Description of Series B Preferred Stock and Warrants".

     Potential  Future   Dilution.   The  following  tables  set  forth  certain
information  if all  outstanding  Series B Preferred  was converted and warrants
exercised as of May 11, 1999.  The times of  convertibility  and  exercisability
vary. See "Recent  Developments - Changes in Capitalization" and "Description of
Series B  Preferred  and  Warrants"  for  information  as to the first  dates of
convertibility and exercisability.

</TABLE>

     Possible Loss of Stock  Exchange  Listing.  The  Company's  Common Stock is
traded on the American  Stock  Exchange  (the  "Amex").  Section 713 of the Amex
Company Guide requires  stockholder  approval of any  transaction  involving the
sale or issuance of Common Stock (or securities  convertible  into Common Stock)
equals 20% or more of  outstanding  Common  Stock and the price is less than the
greater of (i) book  value,  or (ii)  market  value.  The Company did not obtain
approval  of its  stockholders  to issue  the  Series B  Preferred  and does not
anticipate  seeking such  approval  prior to the  conversion  and sale of Common
Stock  thereafter.  As  reflected  in the first chart in the above risk  factor,
conversion  of the Series B Preferred  at the prices below the current bid price
would most likely involve a transaction  relating to the issuance of 20% or more
of the Common Stock of the Company. In addition to Section 713, the Amex has the
authority  under  Section 1003 of the Amex  Company  Guide to delist a security.
Since they have broad authority, while certain guidelines are provided, the Amex
may delist a  security  even if none of the  guidelines  are  violated.  Section
1003(f)(v)  permits  delisting  if the  Common  Stock  has been  "selling  for a
substantial  period of time at a low price per share..." if the Company fails to
effect a reverse split. There can be no assurances that the Amex will not delist
the Company's  Common Stock.  If it does so, the market will be far less liquid.
In turn, this can further depress the price of the Company's Common Stock.

         Change in Short-Term Financial  Condition.  If the Proposed Transaction
closes, the proceeds from the sale of the Assets will substantially  improve the
Company's   short-term   financial  condition  and  liquidity  by  significantly
increasing working capital.  However, as detailed in the next risk factor and in
"Recent  Developments"  there is substantial doubt as to the consummation of the
sale of Assets. However, the Company's results of operations could be materially
and adversely  affected for the short-term if the sale is consummated due to the
loss of TSA profit  contribution.  However, the loss of revenues and income from
the sale of the TSA Assets will be  partially  offset by  projected  annual debt
service savings and corporate  overhead  savings  including  reduced audit fees,
travel  costs  and  other  efficiencies.  See  "Pro  Forma  Condensed  Financial
Information  of the  Company." The funds  available  from the sale of TSA Assets
will be necessary to sustain TSI and pay the Company's  corporate overhead until
TSI is able to generate  substantial  revenues and reduce its operating  losses.
With the improvement in short-term liquidity,  the Company believes it will have
sufficient  working  capital  to  successfully   market  its  OSA-IIs  over  the
long-term.  No  assurances  can be given that the Company  will have  sufficient
working capital or that it will be successful in marketing OSA-IIs.

         Failure of Proposed  Transaction to Close;  Substantial  Doubt that the
Proposed  Transaction  Will Close.  There can be no  assurances  that all of the
conditions  to the Proposed  Transaction  will be satisfied  and that it will be
consummated.  There  currently  is and since  September  30, 1998 there has been
substantial  doubt that NCT Audio Products,  Inc. (the "Proposed Buyer") will be
able to close the Proposed  Transaction.  The reasons for this conclusion are as
follows:

1.   The transaction originally was scheduled to close on or before December 31,
     1998.  The  Proposed  Buyer was  unable to do so and the  closing  date was
     extended to on or before March 31, 1999.  The Proposed  Buyer was unable to
     close on March 31, 1999.
<PAGE>



2.   Because the Proposed  Buyer's failure to close on March 31, 1999 would have
     caused it to lose its  exclusive  right to  purchase  the TSA  Assets,  the
     Proposed Buyer and the Company and TSA entered into an agreement  extending
     the closing to on or before May 28, 1999.

3.   The  components of the $350,000  extension  fee paid by the Proposed  Buyer
     reflects the Proposed Buyer's inability to raise cash to fund the extension
     of its exclusive  right.  The only cash paid was $20,685,  which represents
     interest income on the funds held in escrow that had inadvertently not been
     released to the Proposed Buyer.  The second portion of the extension fee is
     $125,000 of the Proposed Buyer's minority interest in TSA's earnings, since
     the Proposed  Buyer owns 20% of TSA. The final  portion of the $350,000 fee
     represents a $204,315 short-term note due April 16, 1999 (the "Note").

4.   The Note was not and has not been paid.  There are escalating  penalties as
     provided in the  extension  agreement.  The first  penalty is that $145,685
     consisting  of the  $20,685  and  minority  interest  will not be  credited
     against the  $6,500,000,  if the Proposed  Buyer  closes.  In the event the
     closing occurs by May 28, 1999,  none of the $350,000  extension fee can be
     applied as a credit against the $6,500,000.  The most  significant  penalty
     for failure to close by May 28, 1999 is the forfeiture of the potential TSA
     dividends for the succeeding 12 months.

5.   The Proposed  Buyer is a subsidiary of NCT Group,  Inc. which trades on the
     Over-the-Counter  Bulletin Board having been delisted from the Nasdaq Small
     Cap Market  last  year.  The  parent  corporation  reported a loss of $14.2
     million  dollars for 1998 on revenues of $3.3 million  excluding a one time
     licensing fee of $3.2 million.
<PAGE>


6.   In January  1999,  the Proposed  Buyer sought to raise $53 million from the
     sale of debt and preferred stock through a Confidential Offering Memorandum
     (the  "Memorandum").  The sale evidently did not occur,  since the Proposed
     Buyer's parent has announced it received a $40 million  financing  proposal
     from an  institutional  lender which is subject to due diligence.  While we
     have no access to internal  information  concerning  the  viability  of the
     financing,  it  appears  to  be an  extremely  difficult  financing.  It is
     premised  upon the roll-up of three  businesses  including TSA and requires
     $40,000,000 of reasonably  liquid assets as  collateral.  Thus according to
     the Memorandum:

     To  purchase  the TSA  Assets,  the  Proposed  Buyer  must pay the  Company
$6,500,000. But TSA liquid assets are approximately $1,500,000 and substantially
less than 100% of liquid assets is customarily available to be borrowed.

     The second  business is no longer  subject to a binding  agreement with the
Proposed  Buyer.  The expired  agreement  required the Proposed  Buyer to pay it
$10,500,000.

     The third  business,  not  identified  in the  Memorandum,  is scheduled to
receive approximately $24,500,000.

     In order to consummate  this roll-up,  the other two  businesses  must have
approximately  $38,500,000  of allowable  liquid assets to support the remaining
$33,500,000  of the  loan  remaining  after  allocating  $6,500,000  for the TSA
Assets.

         Changing  Technology;  Competitive  Factors.  The  OSA-Is  represent  a
technological  breakthrough affecting the oil analysis industry. Oil analysis is
a 50-year old technology,  which is widely used for diagnostic and  preventative
maintenance  programs for  equipment  by various  industries.  Essentially,  the
OSA-Is  analyze  (and the OSA-IIs are designed to analyze) oil at the end user's
location  thereby  avoiding  the need to send  petroleum  samples  to a  central
laboratory.  The  OSA-Is and  OSA-IIs  utilize  complex  computer  software.  In
general,  the computer industry is subject to rapid and  significantly  changing
technology  including  potential  introduction of new products and technologies,
which may have a material  adverse  impact upon the Company's  ability to market
and sell  OSA-IIs.  Although  the  Company  believes  that it has a  significant
advantage  over  potential  competitors  as a result  of its  experience  over a
five-year  period with the OSA-Is,  the Company's  proprietary  database and the
proprietary nature of the resulting  technology including the development of the
OSA-IIs.  No  assurances  can be given that either a comparable or more advanced
on-site oil  analyzer  will not be  developed in the future by one or more third
parties.

         Patents  and  Proprietary   Information.   Historically,   the  Company
generated  almost all of its revenue from products subject to patents and patent
applications  exclusively  licensed to the Company. TSA has relied upon the sale
of its OHSS  enclosures,  which are covered by a patent  license  limited to the
United  States and Canada.  The Company has obtained  patents  covering  various
features of the OSA-Is  which are  applicable  to the  OSA-IIs.  The Company has
applied for additional  patents  covering  various  features of the OSA-IIs.  In
addition,  steps have been taken to protect  trade secrets  through  appropriate
confidentiality  agreements.   There  can  be  no  assurances  that  the  patent
applications  for the OSA-II  will be  granted.  The  failure by the  Company to
obtain  patents and protect its  respective  trade secrets could have a material
adverse effect on the Company by increasing the  likelihood of  competition.  In
addition,  other  companies  may  independently  develop  equivalent or superior
technologies  and may obtain  patent or  similar  rights  with  respect to them.
Although the Company  believes  that the software for the OSA-Is and OSA-IIs has
been  independently  developed by it, and that such technology does not infringe
on the  patents or violate  the  proprietary  rights of others,  there can be no
assurances  that the Company will not be determined to infringe upon the patents
or proprietary rights of others, or that patents or proprietary rights of others
will not have a  material  adverse  effect  on the  ability  of the  Company  to
commercialize the OSA-IIs.  Patent and technology  disputes are common with high
technology products and services.

         New  Technologies  and Other  Considerations.  In order to  expand  its
current  product  line,  the Company may continue to seek new  technologies  and
products.  This aspect of the  Company's  business  involves a number of special
risks. Because of these risks, the Company will seek capital input and strategic
partners to sell equity in suitable  products and technologies to these partners
in order to reduce the risks to investors.  Also, the Company will seek to avoid
substantial and long-term  expense  associated  with the necessary  research and
development.  Assuming  that the Company is able to enter into  agreements  with
such  partners and that those  partners  will be able to carry out the necessary
research  and  development,  there is the risk  that the  technologies  will not
perform as expected  or be cost  effective.  Assuming  successful  research  and
development,  there  remains the risks of being able to market the  products and
locate industry partners or others able to manufacture the products according to
stringent quality control  standards and in a viable economic manner.  There can
be no  assurances  that the  Company  will be able to  successfully  locate such
technologies and if so, will be able to find strategic  partners able to develop
and market new technologies.  Finally,  there is the risk that while the Company
is  seeking  to  commercialize  a new  technology,  a  competitor  will  develop
technologies,  which are more commercially viable thereby reducing the viability
of the Company's products.

         Anti-Takeover  Considerations.  The Company's  Restated  Certificate of
Incorporation  (the  "Certificate   Provisions")   contains  various  provisions
designed  to deter a third  party  from  launching  a hostile  takeover  for the
Company.  In addition,  the Company has adopted a  Shareholder  Rights Plan (the
"Rights Plan").  In this Prospectus,  the Certificate  Provisions and the Rights
Plan  are  collectively  referred  to as  the  "Anti-Takeover  Provisions".  The
Certificate  Provisions  consist of: (i)  empowering the Board of Directors (the
"Board"),  without further action by the stockholders,  to issue up to 5,000,000
shares  of  Preferred  Stock  in one or more  series,  with  such  designations,
preferences, special rights, qualifications, limitations and restrictions as the
Board may determine;  (ii)  establishing a classified  Board whereby election of
the  directors  is  staggered  and  each  year  approximately  one-third  of the
directors are elected for a three year term; (iii) making it difficult to remove
directors for "cause" by requiring a super-majority  vote of either:  (1) 75% of
the  stockholders,  or (2) 66-2/3% of the  stockholders  and the majority of the
"disinterested  directors";  (iv)  providing  that  stockholder  action taken by
written consent in lieu of a meeting is prohibited unless such consent is signed
by the  holders  of at  least  two-thirds  of the  stock;  and  (v)  restricting
stockholder nomination of directors to any stockholder with the power to vote at
least  15% of the  outstanding  voting  securities  of the  Company  who  timely
complies with specific  notice  procedures.  In connection with the Rights Plan,
the Board  declared  a  dividend  of one  Preferred  Stock  Purchase  Right (the
"Rights") for each  outstanding  share of the Company's Common Stock. The Rights
permit the holders  (stockholders  of the  Company) to purchase  Series A Junior
Preferred  Stock.  Holders  of  Rights  have the right to  acquire  stock of the
Company or an "acquiring  entity" at one-half of market  value.  The Rights only
become  exercisable in the event,  with certain  exceptions,  an acquiring party
accumulates 15 percent or more of the Company's  voting stock.  These Rights may
be  redeemed  by the Company at $.01 per Right prior to the close of business on
the 15th day after a public announcement that beneficial  ownership of ownership
of 15% or more of the  Company's  voting  stock has been  accumulated  by single
acquirer or group (with certain exceptions), under specified circumstances.

         The  Anti-Takeover  Provisions  generally  make  it more  difficult  or
discourage  a proxy  contest  or the  assumption  of  control  by a holder  of a
substantial  block of the Company's Common Stock because it is more difficult to
remove the incumbent Board.  Thus, the  Anti-Takeover  Proposals have the affect
of: (i) entrenching  incumbent  management,  and (ii) discouraging a third party
from  making a tender  offer at a premium  over the  market  price or  otherwise
attempting to obtain control of the Company even though such an attempt could be
desired by a substantial member of the Company's stockholders. The Anti-Takeover
Provisions were not intended to prevent a takeover of the Company on terms which
are beneficial to the stockholders and will not do so. They may, however,  deter
an  attempt  to  acquire  the  Company  in a manner  or on terms  that the Board
determines not to be in the best interest of its stockholders.

        Dependence on Key Personnel. The Company is currently dependent upon the
efforts of the key members of its management  team  consisting of Mr. William C.
Willis, Jr., the Company's President and Chief Executive Officer,  and Mr. David
Natan,  the  Company's  Chief  Financial  Officer.  In addition,  the Company is
dependent upon Dr. John Coates, its Director of Technology,  who is in charge of
the group which  developed  the  OSA-II.  In the event that one or more of these
persons  ceases to be employed by the  Company,  it may have a material  adverse
effect upon the Company.

         Competition.  Competition  in  the  automotive  business  and  the  oil
analysis business is intense. With regard to TSA's OHSS business,  interior trim
suppliers  have  a  substantial  competitive  advantage  as a  result  of  their
relationships  with automobile  manufacturers  and their  substantially  greater
degree of financial  strength,  management depth and engineering  expertise.  By
offering  automobile  manufacturers  the  opportunity  to deal with one  primary
supplier,  an interior trim supplier can offer alternative speaker placement and
thereby competes directly with the Company. With regard to the OSA-II, while the
Company is not aware of any other business that markets and sells an on-site oil
analysis instrument,  the Company's oil analysis subsidiary,  TSI, competes with
various oil analysis  laboratories  located throughout the United States.  These
laboratories  offer service through  Federal  Express or other express  delivery
couriers and provides  facsimile or other rapid delivery of oil analysis reports
to the customers. <PAGE>



                               RECENT DEVELOPMENTS
Sale of TSA

         On August 14, 1998,  the Company and TSA entered into an agreement,  as
amended (the  "Agreement")  with the Proposed  Buyer  through which the Proposed
Buyer  agreed  to  purchase  TSA  for a  minimum  of  $10,000,000  and  up to an
additional  $6,000,000  representing  additional  compensation (the "Earn-Out.")
described on pages ______ of this Prospectus.

         Under the terms of the  Agreement,  the  Proposed  Buyer has  agreed to
assume all of TSA's liabilities  subject to the limitation that such liabilities
not exceed the amount of inventory owned by TSA, and pay the Company $10,000,000
(or $6,500,000 in addition to the $3,500,000  described below).  Since September
30, 1998 the Company has had substantial  doubt as to whether the Proposed Buyer
will have the funds to close the Proposed Transaction. See "Risk Factors Failure
of the  Proposed  Transaction  to Close;  Substantial  Doubt  that the  Proposed
Transaction will Close." The initial anticipated closing date was not later than
December 31,  1998.  This date was extended to March 31, 1999 and now to May 28,
1999 because of the  Proposed  Buyer's  inability  to complete a financing.  See
"Risk Factors".

         The  Proposed  Buyer paid the Company  $1,450,000  as a  non-refundable
deposit in June 1998 and an additional  $2,050,000 on December 15, 1998 when the
Company's stockholders approved the sale. As a result, the Proposed Buyer became
the owner of 20% of TSA.  Pursuant to the Agreement,  the Proposed Buyer had the
exclusive  right to  purchase  the Assets of TSA at any time  through  March 31,
1999. However,  because the Proposed Transaction failed to close by December 31,
1998, the Proposed Buyer had a one-week  option to cancel its exclusive right to
purchase the Assets of TSA and as consideration receive an additional 15% of TSA
Common Stock.  The Proposed Buyer failed to provide  notice to the Company.  The
Proposed  Buyer  remains  the  owner of 20% of TSA  Common  Stock.  However,  in
mid-March,  the Proposed Buyer notified the Company that it would not be able to
close the Proposed Transaction by March 31, 1999. On March 30, 1999, the Company
granted the  Proposed  Buyer an  extension  until May 28,  1999 to complete  the
purchase of TSA. As  consideration  for this extension,  the Company  received a
non-refundable  fee from the Proposed  Buyer of  $350,000.  This  extension  fee
consisted  of $20,685 in cash which the  Company's  counsel had been  holding in
escrow, $125,000 representing the Proposed Buyer's minority earnings of TSA as a
20%  stockholder  of TSA and a $204,315 Note payable due on April 16, 1999.  The
Note was not and has not been paid.  Additionally,  due to the Proposed  Buyer's
failure to close the  transaction  by March 31,  1999,  the Company will receive
$100,000  of  the  Proposed  Buyer's  convertible  preferred  stock.  See  "Risk
Factors".

         If the Proposed  Transaction fails to close by May 28,1999, the Company
will be free to attempt to find another  purchaser of TSA and the Proposed Buyer
will be obligated to sell its TSA shares to any such purchaser on the same terms
and conditions as the Company receives for its TSA Common Stock.

         Assuming  the Proposed  Transaction  had closed in December  1998,  and
assuming  no  changes to TSA's  revenues  and  expenses  after the  closing,  no
Earn-Out  payment if  calculated  on a pro forma basis would have been earned by
the  Company.  The Company  believes  that  current  after-market  and other OEM
production  line  initiatives  in  process  for OHSS will  result in  additional
revenues  that will enable the Company to achieve the full  $6,000,000  Earn-Out
over a two-year period after closing if it occurs. However, no assurances can be
given.

         The  Company  believes  that the  current  aftermarket  and  other  OEM
production  line  initiatives  in  process  for OHSS will  result in  additional
revenues  that will enable the Company to achieve the full  $6,000,000  Earn-Out
over the  two-year  period  following  the  Closing  if it occurs.  However,  no
assurances  can be given.  If earned,  for the first year  following the Closing
("Year One"),  the Proposed  Buyer shall pay TSA an Earn-Out of up to $3,000,000
and a cumulative amount of up to $6,000,000 for Year One and the 12-month period
subsequent to Year One ("Year Two").

         The  Earn-Out  in Year One  shall be equal to the  amount  by which the
product of four and  one-half  times  EBITDA,  as defined,  for Year One exceeds
$8,000,000.  As used in the Agreement,  "EBITDA"  means income before  interest,
taxes,   depreciation  and  amortization  of  the  Proposed  Buyer's  subsidiary
acquiring  the Assets ("New TSA").  The Agreement  further  provides that EBITDA
shall be based  solely  upon the  operations  of New TSA based  upon  operations
consistent  with the historical  operations of TSA and excluding items of income
or expense such as non-recurring items,  extraordinary items, intercompany items
and other items of income and expense  which are not  consistent  with such past
practice.

         In  effect,  to the  extent  that in Year One the cash  flow of New TSA
times four and one-half  exceeds  $8,000,000,  the Proposed  Buyer shall pay the
Earn-Out up to the maximum of  $3,000,000.  The Year Two Earn-Out shall be equal
to the amount by which the product of four and  one-half  times  EBITDA for Year
Two exceeds the greater of: (i) Year One EBITDA times four and one-half, or (ii)
$8,000,000.  The maximum  Year Two  Earn-Out  calculated  using this  formula is
$6,000,000 minus the Year One Earn-Out.


Changes in Capitalization

         In December 1998, the Company received  $3,500,000 from the sale of its
Series B Preferred to two trusts in which Mr. G. Jeff Mennen,  a director of the
Company, is a co-trustee and sole trustee,  respectively,  and the beneficiaries
of which are members of Mr. Mennen's immediate family (the "Mennen Trusts"). The
Series B Preferred is  convertible on or after November 1, 1999 into a number of
shares of Common Stock computed by dividing the stated value of $1,000 per share
(the "Stated  Value") by 85% of the closing bid price of the Common Stock on the
previous trading day (the "Conversion Price"). The Company shall have the option
to redeem the Series B Preferred at 110% of Stated Value plus accrued  dividends
at any time before  April 30,  1999 and at a price of 115% of Stated  Value plus
accrued  dividends  commencing  on May 1, 1999 and expiring on October 27, 1999.
The Series B Preferred  pays a dividend of 9% per annum in cash.  As part of the
agreements with its lenders described below, the Company obtained  permission to
pay cash dividends to the Mennen Trusts.  However,  if in the future the Company
is unable  to pay cash  dividends,  they  shall be  payable  in shares of Common
Stock. The aggregate number of shares of Common Stock to be issued to the Mennen
Trusts in such event shall equal the sum of: (x) the amount of the  dividend per
share (or $90 per  annum)  divided by the  Conversion  Price plus (y) 25% of the
amount  obtained  in clause  (x),  which sum shall be  multiplied  by 3,500.  As
additional  consideration,  the Company issued to the Mennen Trusts  Warrants to
purchase  350,000  shares of the  Company's  Common  Stock  ("Class D Warrants")
exercisable  over a 10-year period at a price of  approximately  $1.94 per share
(or $1.00 above the  closing  price on the day of  consummation  of the Series B
Preferred sale  transaction).  Additionally,  because the Series B Preferred was
not  redeemed or  converted  into Common  Stock on or before May 1, 1999,  ( the
Company  issued to the  Mennen  Trusts an  additional  50,000  10-year  Warrants
exercisable  at a price  of $.50  per  share  above  the  closing  price  of the
Company's  Common  Stock  on  April  30,  1999 or  $1.75  per  share  ("Class  E
Warrants").  Not later than November 30, 1999,  the Company has agreed to file a
registration  statement  to cover the public sale of the shares of Common  Stock
issuable on conversion of the Series B Preferred and exercise of the Class D and
E  Warrants  as well as the  Class  F  Warrants  described  below.  The  Company
consummated this transaction  after diligently and actively seeking  alternative
financing  sources and  concluding  that the  proposal was superior to competing
offers available in strict arms-length transactions. The Board voted unanimously
to approve the sale of the Series B Preferred  with Mr. Mennen  abstaining.  The
shares of Common Stock  underlying  the Series B Preferred and the Class D and E
Warrants  underlying  are not covered by this  Prospectus  and may not be resold
pursuant to this Prospectus.

         In January 1998, the Company recognized it might in fiscal 1998 violate
a covenant  contained  in  $3,020,000  of  Subordinated  Convertible  Notes (the
"Notes")  issued in 1995.  In order to assure the  Company's  auditors  that the
Company had the  ability to comply  with this  financial  covenant,  Mr.  Mennen
agreed to infuse  sufficient  capital into the Company as may be  necessary.  In
exchange for Mr. Mennen's commitment,  the Company issued to him 50,000 Warrants
exercisable  at $2.00 per share (the "Class F Warrants").  Following the closing
of the Series B Preferred sale, the Company redeemed one-half or $500,000 Stated
Value of the existing  Series A Preferred by paying the  Purchasers an aggregate
purchase  price of $600,000.  In late 1998,  the remaining  $150,000 of Series A
Preferred  converted  into an aggregate of 387,554 shares of Common Stock (which
sum included  accrued  dividends) in  accordance  with the terms of the Series A
Preferred.  As consideration for the initial delay in converting $350,000 of the
Series A Preferred, the Company issued to the two Purchasers Class B Warrants to
purchase  an  aggregate  of  25,000  shares  of  Common  Stock   exercisable  at
approximately  $.89 per share  commencing  in April  1999.  The shares of Common
Stock  reserved for exercise of the Class B Warrants are being  offered for sale
pursuant to this Prospectus.

         The  Purchasers  also agreed not to convert the  remaining  $350,000 of
Series A  Preferred  until  March 31,  1999.  On that date,  one of the  Selling
Stockholders,  Excalibur Limited Partnership  ("Excalibur"),  acquired the other
Purchaser's Series A Preferred and converted all $350,000 into 350,000 shares of
Common  Stock or at $1.00 per  share.  This was  substantially  higher  than the
actual conversion price thereby reducing the dilution to existing  stockholders.
Additionally,  Excalibur  agreed that the 350,000 shares of Common Stock,  which
will be eligible for resale under Rule 144 in May 1999,  shall not be sold prior
to October 1,1999, and then only up to a maximum of 70,000 shares per month.

         The Company has  restructured  substantially  all of its  $3,020,000 of
Notes.  With a portion of the proceeds from the Series B Preferred,  the Company
prepaid  an  aggregate  of  $745,000  principal  amount  of Notes  for  $496,617
resulting in savings of $248,383 in principal  amount (not including future debt
service costs).  In connection with the discounting of these Notes,  the Company
issued to the  noteholders  Class C Warrants to purchase an aggregate of 248,383
shares of the  Company's  Common Stock  exercisable  over a five-year  period at
approximately  $1.78 per share. The shares of Common Stock reserved for exercise
of the Class C Warrants  may be sold  pursuant to this  Prospectus.  The Company
entered into an agreement  with the agent for the remaining  noteholders,  which
modified the remaining  Notes. The Company prepaid such noteholders an aggregate
of  $1,568,000  in  principal  amount of Notes (at the rate of $.70 per $1.00 of
principal).  These noteholders continue to hold Notes in the principal amount of
$707,000.  Additionally,  the interest  rate was reduced from 9% per annum to 5%
per annum on the Notes and the conversion price reduced from $10 per share to $2
per  share.  As  part of the  Amendment  to the  Note  Purchase  Agreement,  the
remaining  noteholders  waived  certain  restrictive  provisions  including  the
requirement  that the Company  maintain a 1.5 to 1.0 debt to equity  ratio which
waiver  continues  through  and  including  September  30,  1999  which  is  the
conclusion of the Company's current fiscal year.

         The  Company  has also  obtained a waiver  from its  principal  lender,
NationsCredit  Commercial  Funding  ("NationsCredit"),  of the of the  financial
covenant  precluding the Company from having a loss of more than $2,000,000 in a
fiscal year. In conjunction with such waiver,  the Company paid  NationsCredit a
fee of $25,000  and agreed to  collaterally  assign a  $250,000  certificate  of
deposit to NationsCredit.

Formation of Strategic Alliance with Flying J

         In November  1998, the Company  entered into a strategic  alliance with
Flying J, a company  engaged in various facets of  highway-related  products and
services  including  the  operation  of large  truck  stops.  Flying J agreed to
purchase and market  OSA-IIs in up to 100 of their truck stop  service  centers.
The initial  purchase order is for 10 OSA-IIs;  the agreement covers a potential
purchase of up to 100 OSA-IIs, payment of a per sample technology licensing fee,
and joint  development  and marketing of product  enhancements  to assist in the
further  commercialization of the OSA-IIs within the truck stop industry.  After
receipt of the initial 10 OSA-IIs,  Flying J may terminate the agreement without
any  liability.  Flying J paid the  Company  for the first 10 units  during  the
quarter ending March 31, 1999. The Company  recognized  revenue of approximately
$280,000 for the quarter ended March 31, 1999 representing four units which were
delivered to Flying J during the quarter.  An additional  six OSA-II's have been
installed at Flying J  facilities  during the quarter  ending June 30, 1999.  In
addition to the purchase price of the OSA-II units, Flying J is obligated to pay
the Company a per sample  licensing fee, which is reduced at such time as Flying
J has 36 OSA-II units  operating.  In  addition,  in  recognition  of Flying J's
efforts to assist the  Company in  commercializing  the OSA-II  within the truck
stop industry,  it will receive financial incentives subject in part to Flying J
having at least 36 OSA-II units in operation. The Company is currently reviewing
potential modifications to the OSA-II unit in order to make it a self-serve unit
which can operate  quietly and be placed in up to 100 of Flying J's truck stops.
While the Company  believes the proposed changes are technically  feasible,  the
costs of modification may approximate  $150,000.  The Company does not intend to
modify the unit unless  Flying J bears this cost.  The Company only  anticipates
selling to Flying J a limited  number of OSA IIs during the  remainder  of 1999.
These units will be installed in Flying J's full  service  plazas,  which do not
require a  self-serve  OSA-II.  There can be no  assurances  that  Flying J will
decide  to  purchase  any of the  additional  90  OSA-IIs  or that  any  further
commercialization  of the  OSA-IIs  within  the truck stop  industry  will prove
successful.

Other Matters

         As  previously  publicly  reported,  Mr. Stuart  Landow,  the Company's
former  Chairman  of the  Board,  resigned  as a  director  and  as an  employee
effective June 30, 1998.

         Mr. William C. Willis, Jr., the Company's president and chief executive
officer and new Chairman of the Board waived a bonus of $127,500 to which he was
entitled under his employment  agreement.  In exchange for this waiver,  in July
1998 the  Company's  Compensation  Committee  granted Mr.  Willis  100,000 stock
options  exercisable  at $.875 per share (then fair market  value).  The options
vest  incrementally  over a three-year period and are exercisable over a 10-year
term. Mr. Willis initiated this transaction as a result of the Company's efforts
to conserve cash and his confidence in the Company.

New Accounting Standards

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 131,  "Disclosures about Segments
of an Enterprise  and Related  Information",  which is required to be adopted in
fiscal years  beginning  after  December 15, 1997.  This  statement  establishes
standards  for the way public  business  enterprises  report  information  about
products, services, geographic areas and major customers. The Company will adopt
SFAS No. 131 or for fiscal year ended  September 30, 1999.  The adoption of SFAS
No. 131 will not have a material impact on its financial  position or results of
operations. <PAGE>


                                     PRO FORMA CONDENSED FINANCIAL
                                        INFORMATION OF THE COMPANY

       The following  unaudited pro forma  condensed  financial  statements were
prepared to reflect the estimated  effects of the potential  sale of 100% of TSA
for  $10,000,000.  The sale is  structured to occur in three  separate  steps as
follows: (i) The Company has received a $1,450,000  non-refundable deposit which
gave the Buyer a minimum of a 14.5% equity  interest in TSA ("Step 1"), (ii) the
Second  Payment of $2,050,000 was paid into escrow on July 30, 1998 and released
to the Company  (became  non-refundable)  on December 15, 1998 as a result of an
affirmative  shareholder approval which gave the Buyer an additional 5.5% of TSA
Common  Stock  ("Step 2"),  and (iii) the receipt of the  remaining  proceeds of
$6,500,000  to complete the  ultimate  sale of 100% of TSA which was to occur by
March 31, 1999 ("Step 3").

         As a result of the completion of Steps I and II of the transaction, the
Buyer  became a 20% owner of the Common  Stock of TSA.  On January 7, 1999,  the
Buyer of TSA's  Assets,  by virtue of not  exercising  its right to  receive  an
additional 15% minority stake in TSA maintained its exclusive  right to complete
the remainder of the transaction by March 31, 1999. As a result,  the Buyer will
remain as a 20%  minority  owner of TSA unless  Step III of the  transaction  is
completed.

        On March 30,  1999,  the Parent  Company  granted the Buyer an extension
until May 28, 1999 to complete  the purchase of TSA. As  consideration  for this
extension,  the Parent Company received a  non-refundable  fee from the Buyer of
$350,000.  This  extension  fee  consisted  of $20,685 in cash,  $125,000 of the
Buyer's  minority  interest in TSA earnings  and a $204,315  note payable due on
April 16, 1999 (the "Note") from the Buyer to TSA. Additionally, due to the

Buyer's  failure to close the  transaction by March 31, 1999, the Parent Company
received a penalty  premium of  $100,000 of the  Buyer's  convertible  preferred
stock. ( See page xx for further discussion ).

         If the  transaction  fails to close by May 28, 1999, the Parent Company
intends to operate TSA and will be free to attempt to find another  purchaser of
TSA. The Buyer will be obligated to sell its TSA shares to any such purchaser on
the same terms and conditions as the Company  receives for its TSA Common Stock.
For a discussion of the risks involved in this event,  see "Risk Factors Failure
of Proposed Transaction to Close".

         The  unaudited pro forma  condensed  balance sheet as of March 31, 1999
gives  effect to the above  transactions  as if they had  occurred  on March 31,
1999. The unaudited pro forma  condensed  statements of operations for the years
ended  September  30,  1998  and  1997 and 1996  give  effect  to the pro  forma
transactions  as if they had  occurred  as of  October  1, the  first day of the
Company's  respective fiscal year. The unaudited pro forma condensed  statements
of  operations  for the six months  ended March 31, 1999 and 1998 give effect to
the pro  forma  transactions  and the  proceeds  from  the  sale of the  sale of
$3,500,000 of Series B Convertible  Stock and the repayment of $2,313,000 of the
Senior Convertible Notes, as if they had occurred as of October 1, the first day
of the Company's respective fiscal year. Upon the sale of 100% of the TSA Assets
(Step 3), this segment will be treated as a discontinued operation as defined in
Accounting Principals Board Opinion No. 30, accordingly the pro forma statements
of  income  have  been  presented  for all the same  periods  as the  historical
financial statements.

         The  unaudited  pro  forma  condensed  financial  statements  were also
prepared to show the effects of the use of the net proceeds from the sale to pay
Nations as described in the notes to the unaudited pro forma condensed financial
statements.

         The unaudited pro forma  condensed  financial  statements were prepared
utilizing the accounting principles of the Company as outlined in its historical
financial  statements  included in the Company's  Form 10-K/A No. 2 for the year
ended  September 30, 1998 and Form 10-K/A No. 3 for the year ended September 30,
1997,  a copies of which are  incorporated  by reference  herein.  The pro forma
adjustments are based upon available  information and contain  assumptions  that
the Company believes are reasonable under the  circumstances.  The unaudited pro
forma  condensed  financial  statements do not reflect the  potential  corporate
overhead savings as a result of the sale of TSA.

        All of the shares of Common  Stock are  offered  for sale by the Selling
Stockholders  as listed in this  Prospectus  under "Selling  Stockholders".  The
Company will receive none of the proceeds  from the sale of the shares of Common
Stock by the Selling  Stockholders.  However, the Company will receive a maximum
of approximately $739,622 in connection with the exercise of up to 100,000 Class
A 25,000 Class B and 248,383 Class C Warrants,  the underlying  shares of Common
Stock of which are covered by this  Prospectus.  Such  proceeds will be used for
general corporate purposes.

        The Company has been advised by the Selling Stockholders that the shares
of Common Stock may be offered and sold from time to time by or on behalf of the
Selling  Stockholders,  in or through  transactions or distributions  (including
crosses  and block  transactions)  on the  American  Stock  Exchange,  or in the
over-the-counter  market at market prices  prevailing at the time of sale, or at
negotiated  prices,  and in  connection  therewith  commissions  may be  paid to
brokers.  Brokers  participating in such  transactions may act as agents for the
Selling Stockholders. The Selling Stockholders, and any brokers participating in
this  offering  may be deemed to be  "underwriters"  within  the  meaning of the
Securities  Act,  and any  commissions  received  by them  may be  deemed  to be
underwriting compensation.

Item 15. Indemnification of Directors and Officers.

         The  Company's  amended  and  restated   certificate  of  incorporation
provides  that the Company shall  indemnify its current and former  officers and
directors  against  expenses  reasonably  incurred  by or  imposed  upon them in
connection  with or arising out of any action,  suit or proceeding in which they
may be involved or to which they may be made parties by reason of their being or
having  been a director or officer of the  Company,  or at its  request,  of any
other  corporation  which it is a  stockholder  or creditor  and from which such
officers and  directors  are not entitled to be  indemnified  by (whether or not
they  continue to be  directors or officers at the time of imposing or incurring
such  expense),  except in  respect of matters as to which they shall be finally
adjudged in such action, suit or proceeding liable for negligence or misconduct.
In  the  event  of   settlement  of  any  such  action,   suit  or   proceeding,
indemnification  shall be provided only in connection  with such matters covered
by the settlement as to which the Company is advised by counsel that the persons
to be  indemnified  did not  commit a breach  of duty.  The  foregoing  right of
indemnification shall not be exclusive of other rights to which such persons may
be entitled.

         In addition,  the Company has entered into  indemnification  agreements
with its executive  officers and directors.  These  agreements  provide that the
Company shall  indemnify its executive  officers and directors,  if by reason of
their  corporate  status,  they are or are  threatened to be made parties to any
third-party  proceedings,  to the fullest  extent  provided by Delaware law. The
agreements provide for indemnification against expenses,  judgments,  penalties,
fines and amounts paid in settlement,  actually and reasonably  incurred by them
or on their behalf in connection  with such  proceeding  or any claim,  issue or
matter therein if (i) they acted in good faith; (ii) they reasonably believed in
the case of conduct  in their  official  capacity  with the  Company  that their
conduct was in the Company's  best  interests or in all other cases,  that their
conduct was at least not opposed to the  Company's  best  interests;  (iii) with
respect to any  criminal  proceeding,  they had no  reasonable  cause to believe
their  conduct was unlawful;  and (iv) with respect to an employee  benefit plan
they  reasonably  believed  their  conduct  to be in the best  interests  of the
participants and/or  beneficiaries of the plan. The  indemnification  agreements
also provide  indemnification  in direct and  derivative  actions  provided such
officers  or  directors  acted in good  faith  and in a manner  they  reasonably
believed to be not opposed to the best  interests of the Company.  Such officers
or  directors  are not  entitled  to  indemnification  in  connection  with  any
proceeding  charging  improper  personal benefits to such officers or directors,
whether or not involving action in their official  capacity,  in which they were
judged  liable on the basis that  personal  benefit was  improperly  received by
them.

         INSOFAR AS INDEMNIFICATION FOR LIABILITIES ARISING UNDER THE SECURITIES
         ACT  OF  1933  MAY BE  PERMITTED  TO  DIRECTORS,  OFFICERS  OR  PERSONS
         CONTROLLING  THE COMPANY  PURSUANT  TO THE  FOREGOING  PROVISIONS,  THE
         COMPANY HAS BEEN  INFORMED  THAT IN THE OPINION OF THE  SECURITIES  AND
         EXCHANGE  COMMISSION,  SUCH INDEMNIFICATION IS AGAINST PUBLIC POLICY AS
         EXPRESSED IN THE SECURITIES ACT AND IS THEREFORE UNENFORCEABLE.

Item 17. Undertakings.

         The undersigned Registrant hereby undertakes:

         (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
                           (the "Securities Act");

                  (ii)     To  reflect  in the  Prospectus  any  facts or events
                           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 paragraphs (1)(i) and (1)(ii) do not apply if
the information  required to be included in a post-effective  amendment by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission  by the  Registrant  pursuant  to Section 13 or Section  15(d) of the
Exchange Act that are incorporated by reference in the registration statement.

(2)  That,  for the purpose of  determining  any liability  under the Securities
     Act,  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
     bonafide 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.

(4)  That, for purposes of determining  any liability  under the Securities Act,
     each filing of the Registrant's  annual report pursuant to section 13(a) or
     section 15(d) of the Exchange Act that is  incorporated by reference in the
     registration  statement 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.

(5)  The  undersigned  Registrant  hereby  undertakes  to deliver or cause to be
     delivered  with the  Prospectus,  to each person to whom the  Prospectus is
     sent or given,  the  latest  annual  report  to  security  holders  that is
     incorporated  by reference in the Prospectus and furnished  pursuant to and
     meeting the  requirements  of Rule 14a-3 or Rule 14c-3  under the  Exchange
     Act; and, where interim financial  information  required to be presented by
     Article  3 of  Regulation  S-X are  not set  forth  in the  Prospectus,  to
     deliver,  or cause to be delivered to each person to whom the Prospectus is
     sent  or  given,   the  latest   quarterly   report  that  is  specifically
     incorporated  by  reference  in the  Prospectus  to  provide  such  interim
     financial information.

(6)  Insofar as indemnification for liabilities arising under the Securities Act
     may be permitted to  directors,  officers  and  controlling  persons of the
     Registrant  pursuant to the foregoing  provisions  (see Item 15 above),  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 Securities 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  Securities  Act and will be
     governed by the final adjudication of such issue.

dated  November 16, 1998  modifying the terms and  conditions of the Series A 5%
Convertible  Preferred Stock (the  "Agreement")  and is subject to its terms and
conditions.

1. Title of Warrant.  Prior to the  expiration  hereof and subject to compliance
with applicable laws, this Warrant and all rights hereunder are transferable, in

person or by duly authorized  attorney,  upon surrender of this Warrant together
with the Assignment Form annexed hereto properly endorsed.

2.  Authorization  of Shares.  The Company  covenants  that all shares of Common
Stock  which may be issued  upon the  exercise  of  rights  represented  by this
Warrant will,  upon exercise of the rights  represented by this Warrant and full
payment of the Exercise Price, be duly  authorized,  validly issued,  fully paid
and nonassessable  and free from all taxes,  liens and charges in respect of the
issue  thereof   (other  than  taxes  in  respect  of  any  transfer   occurring
contemporaneously with such issue).

3. Exercise of Warrant. Except as provided in Section 11 herein, exercise of the
purchase  rights  represented by this Warrant may be made in whole or in part at
any time ending  before the close of business on the  Termination  Date, or such
earlier date on which this Warrant may terminate as provided in this Warrant, by
the  surrender  of this Warrant and the Notice of Exercise  Form annexed  hereto
duly  executed,  at the office of the Company (or such other office or agency of
the Company as it may  designate by notice in writing to the  registered  holder
hereof at the address of such holder  appearing on the books of the Company) and
upon payment of the Exercise  Price of the shares thereby  purchased;  whereupon
the holder of this Warrant  shall be entitled to receive a  certificate  for the
number of shares of Common Stock so purchased. Certificates for shares purchased
hereunder  shall be delivered to the holder hereof within four (4) business days
after the date on which this Warrant shall have been exercised as aforesaid,  or
be subject to the damages set forth in the  Agreement.  Payment of the  Exercise
Price may be by  certified  check or cashier's  check or by wire  transfer to an
account  designated  by the  Company in an amount  equal to the  Exercise  Price
multiplied by the number of Warrant Shares.

fractional shares shall be issued upon the exercise of this Warrant.  Fractional
Shares shall be rounded down as provided for in Section 5(g) of the  Certificate
of Designation.

5. Charges,  Taxes and Expenses.  Issuance of certificates  for shares of Common
Stock upon the  exercise of this  Warrant  shall be made  without  charge to the
holder  hereof  for any issue or  transfer  tax or other  incidental  expense in
respect of the  issuance of such  certificate,  all of which taxes and  expenses
shall be paid by the Company,  and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant;  provided,  however,  that in the event certificates for
shares of Common  Stock  are to be issued in a name  other  than the name of the
holder of this  Warrant,  this Warrant when  surrendered  for exercise  shall be
accompanied by the Assignment  Form attached  hereto duly executed by the holder
hereof, and provided further, that upon any transfer involved in the issuance or
delivery  of any  certificates  for  shares of Common  Stock,  the  Company  may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

6. Closing of Books.  Unless otherwise  required by law or the principal trading
market  for  the  Company's  Common  Stock,  the  Company  will  not  close  its
shareholder books or records in any manner which prevents the timely exercise of
this Warrant for a period of time in excess of five (5) trading days per year.

7. No Rights as Shareholder  until  Exercise.  This Warrant does not entitle the
holder  hereof to any  voting  rights or other  rights as a  shareholder  of the
Company  prior to the exercise  thereof.  Upon the surrender of this Warrant and
the payment of the aggregate  Exercise  Price,  the Warrant  Shares so purchased

shares as of the close of business on the later of the date of such surrender or
payment.

surrender of this Warrant and the  Assignment  Form annexed hereto duly executed

it may  designate by notice in writing to the  registered  holder  hereof at the
address  of such  holder  appearing  on the  books  of the  Company);  provided,
however,  that the Company may require, as a condition thereto, the payment of a
sum sufficient to reimburse it for any expenses of transfer  incidental  thereto
and that this Warrant may not be resold or otherwise transferred except (I) in a
transaction  registered under the Securities Act of 1933 (the "Securities Act"),
or (ii) in a  transaction  pursuant to an  exemption,  if  available,  from such
registration  and whereby,  if  requested by the Company,  an opinion of counsel
reasonably  satisfactory to counsel for the Company is obtained by the holder of
this Warrant to the effect that the transaction is so exempt.

9. Loss, Theft, Destruction or Mutilation of Warrant. The Company represents and
warrants that upon receipt by the Company of evidence reasonably satisfactory to
it of the loss, theft,  destruction or mutilation of this Warrant certificate or
any stock certificate relating to the Warrant Shares, and in case of loss, theft
or destruction, of indemnity or security reasonably satisfactory to it, and upon
reimbursement to the Company of all reasonable expenses incidental thereto,  and
upon  surrender  and  cancellation  of such  Warrant  or stock  certificate,  if
mutilated,  the Company will make and deliver a new Warrant or stock certificate
of like  tenor and dated as of such  cancellation,  in lieu of such  Warrant  or
stock certificate.

10.  Saturdays,  Sundays,  Holidays,  etc. If the last or appointed  day for the
taking of any action or the  expiration of any right  required or granted herein
shall be a Saturday,  Sunday or a legal  holiday in the State of New York,  then
such action may be taken or such right may be exercised  on the next  succeeding
day not a legal holiday.

11.      Effect of Certain Events.

(a) If at any time the Company  proposes (i) to sell or otherwise  convey all or
substantially  all of its assets or (ii) to effect a  transaction  (by merger or
otherwise) in which more than 50% of the voting power of the Company is disposed
of (collectively, a "Sale or Merger Transaction"), in which the consideration to
be received by the Company or its shareholders consists solely of cash, then the
Warrant shall  terminate if the Warrant has not been  exercised by the effective
date of such Sale or Merger  transaction,  the Company  shall give the holder of
this  Warrant  thirty (30) days notice of such  termination  and of the proposed
effective date of the Sale or Merger transaction.

(b) In case the Company shall at any time effect a Sale or Merger Transaction in
which the  consideration  to be  received  by the  Company  or its  shareholders
consists  in whole or in part of  consideration  other than cash,  the holder of
this Warrant shall have the right  thereafter  to purchase,  by exercise of this
Warrant and payment of the aggregate  Exercise Price in effect immediately prior
to such action,  the kind and amount of shares and other securities and property
which it would have owned or have been  entitled to receive  after the happening
of such Sale or Merger  transaction had this Warrant been exercised  immediately
prior thereto.


(c)      "Piggy-Back" Registration.

(i) The  holder  of this  Warrant  shall  have the right to  include  all of the
Warrant Shares (the  "Registrable  Securities")  as part of any  registration of
securities  filed by the Company  (other than in  connection  with a transaction
contemplated by Rule 145(a)  promulgated under the Securities Act or pursuant to
Forms S-4 or S-8) and must be  notified  in writing of such  filing.  The holder
shall have five (5) business days to notify the Company in writing as to whether
the  Company  is to  include  holder's  Registrable  Securities  as  part of the
registration;  provided,  however,  that if any  registration  pursuant  to this
Section shall be underwritten, in whole or in part, the Company may require that
the Registrable  Securities  requested for inclusion pursuant to this Section be
included in the  underwriting on the same terms and conditions as the securities
other-wise being sold through the underwriters. If in the good faith judgment of
the underwriter of such offering only a limited number of Registrable Securities
should be included in such offering,  or no such shares should be included,  the
holder of such Registrable Securities, and any other selling stockholders, shall
be reduced,  such  reduction  to be applied by  excluding  (on a pro rata basis)
Registrable  Securities  proposed  to be sold by the holder of this  Warrant and
shares proposed to be sold by all other persons.  Those  Registrable  Securities
which are not included in an  underwritten  offering  pursuant to the  foregoing
provisions  of this Section (and all other  Registrable  Securities  held by the
selling  stockholders)  shall be withheld from the market by the Holders thereof
for a  period,  not to exceed  ninety  (90)  days,  which  the  underwriter  may
reasonably  determine-nine  is  necessary  in order to effect such  underwritten
offering,  and the Holder shall sign any  agreement to this effect  requested by
such  underwriter.  Notwithstanding  the foregoing  provisions,  the Company may
withdraw any  registration  statement  without  incurring  any  liability to the
holders of Registrable Securities.

(ii) The registration  rights set forth in Section 11(c)(i) shall cease upon the
earliest of (A) the effective  registration  under the  Securities Act of all of
the Registrable  Securities and the disposal of such securities pursuant to such
registration,  (B)  registration  under the Securities Act is no longer required
for the  immediate  public  distribution  of such  security  as a result  of the
provisions  of Rule  144  promulgated  under  the  Securities  Act,  or (C) such
Registrable Securities cease to be outstanding.

12.  Adjustments-of  Exercise Price and Number of Warrant Shares. The number and
kind of  securities  purchasable  upon  the  exercise  of this  Warrant  and the
Exercise  Price  shall be  subject  to  adjustment  from  time to time  upon the
happening of any of the following.

In case the  Company  shall (i)  declare or pay a  dividend  in shares of Common
Stock or make a  distribution  in  shares  of  Common  Stock to  holders  of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
(iii) combine its  outstanding  shares of Common Stock into a smaller  number of
shares  of Common  Stock or (iv)  issue any  shares  of its  capital  stock in a
reclassification  of the  Common  Stock,  then  the  number  of  Warrant  Shares
purchasable  upon  exercise of this Warrant  immediately  prior thereto shall be
adjusted  so that the holder of this  Warrant  shall be  entitled to receive the
kind and number of Warrant  Shares or other  securities  of the Company which he
would  have  owned or have  been  entitled  to  receive  had such  Warrant  been
exercised in advance thereof Upon each such adjustment of the kind and number of
Warrant  Shares  or  other  securities  of the  Company  which  are  purchasable
hereunder,  the holder of this Warrant shall  thereafter be entitled to purchase
the number of Warrant Shares or other securities  resulting from such adjustment
at an  Exercise  Price per such  Warrant  Share or other  security  obtained  by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares  purchasable  pursuant hereto  immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company  resulting from such  adjustment.  An adjustment made pursuant to
this paragraph shall become  effective  immediately  after the effective date of
such event retroactive to the record date, if any, for such event.

13. Voluntary  Adjustment by the Company. The Company may at any time during the
term of this Warrant,  reduce the then current  Exercise Price to any amount and
for any  period of time  deemed  appropriate  by the Board of  Directors  of the
Company.

14.  Notice of  Adjustment.  Whenever the number of Warrant  Shares or number or
kind of  securities  or other  property  purchasable  upon the  exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested,  to the
holder of this Warrant notice of such  adjustment or  adjustments  setting forth
the number of Warrant Shares (and other securities or property) purchasable upon
the exercise of this Warrant and the Exercise  Price of such Warrant Shares (and
other  securities  or property)  after such  adjustment,  setting  forth a brief
statement  of  the  facts  requiring  such  adjustment  and  setting  forth  the
computation  by which  such  adjustment  was made.  Such  notice,  in absence of
manifest  error,  shall  be  conclusive  evidence  of the  correctness  of  such
adjustment.

15. Authorized  Shares. The Company covenants that during the period the Warrant
is outstanding,  it will reserve from its authorized and unissued Common Stock a
sufficient  number of shares to provide for the  issuance of the Warrant  Shares
upon the exercise of any purchase rights under this Warrant. The Company further
covenants that its issuance of this Warrant shall  constitute  full authority to
its officers who are charged with the duty of executing  stock  certificates  to
execute and issue the  necessary  certificates  for the Warrant  Shares upon the
exercise of the purchase  rights under this  Warrant.  The Company will take all
such  reasonable  action as may be necessary to assure that such Warrant  Shares
may be issued as 'provided  herein  without  violation of any  applicable law or
regulation,  or of any  requirements  of prove the  NASDAQ  Stock  Market or any
domestic securities exchange upon which the Common Stock may be listed.

Mr. Michael J. Parrella
President
NCT Audio Products, Inc.
One Dock Street, Suite 100
Stamford, CT  06902

RE:      Top Source Technologies, Inc./NCT Audio Products, Inc.

Dear Mr. Parrella:

Extension Terms

         This  letter  confirms  our recent  discussions  to the effect that NCT
Audio Products,  Inc. ("NCT") will not be able to close on its proposed purchase
of the assets of Top Source Automotive, Inc. ("TSA") by March 31, 1999. In order
to maintain the exclusive  right to purchase the assets of TSA, NCT shall pay to
TSA the total sum of $350,000 (the "Extension Fee") on or before 5:00 p.m. Miami
time on March 30, 1999. This Extension Fee consists of (i) a $204,315 Note; (ii)
$20,685  currently  held in escrow for the benefit of NCT and (iii)  $125,000 of
TSA minority equity  earnings.  If NCT pays the Note by 5:00 p.m. April 16, 1999
and closes the  transaction by May 28, 1999, the Extension Fee shall be credited
in full against the $6,500,000  balance due at closing.  If NCT fails to pay the
Note by  April  16,  1999 or fails to close  the  transaction  by May 28,  1999,
certain penalties will apply. See Penalty Provisions below. As an option premium
and not part of the  Extension  Fee,  NCT shall  deliver to TSA as  promptly  as
possible $100,000 of NCT's convertible preferred stock, which stock shall not be
credited toward the balance of $6,500,000 due to TSA or otherwise credited.  The
number of shares of Convertible  Preferred Stock comprising the $100,000 will be
determined  based upon a valuation of NCT Audio by its primary  investors and/or
underwriters.  It is the intent of the parties that this  convertible  preferred
stock shall be a premium for granting the extension and shall be retained by TSA
regardless  of  whether  the  transaction  closes  on May 28,  1999 or any  time
thereafter,  or if at all. In exchange for the Extension Fee and Preferred Stock
consideration,  NCT shall retain the  exclusive  right to purchase the assets of
TSA until 5:00 p.m. Miami time on May 28, 1999.

                           17,  1999 at the rate of two times  prime rate or the
                           highest rate allowable by law, whichever is lowest.

                  b.       In the  event  that the Note is not paid by April 16,
                           1999,  the  $20,685  and  $125,000   portion  of  the
                           Extension Fee shall no longer be credited  toward the
                           $6,500,000  closing amount due. This provision  shall
                           apply even if the transaction closes by May 28, 1999.

         2. Failure to Pay the Note by April 30, 1999.

                  In addition to Penalty  Provision (1. b.) above,  in the event
                  the Note and accrued  interest is not paid by April 30,  1999,
                  the $204,315  portion of the  Extension Fee shall no longer be

                  28, 1999.

         3.        Failure to Pay the Note Prior to Closing.

                  In the event the Note is not paid prior to  closing,  it shall
                  be added along with accrued  interest to the $6,500,000 due at
                  closing.   Therefore,  the  amount  due  at  closing  will  be
                  $6,704,315, plus accrued interest.

         4. Failure to Close by May 28, 1999.

                  a.       If NCT  fails to  close  the  transaction  by May 28,
                           1999, the $350,000 Extension Fee shall be retained by
                           TSA and shall not be refundable or  convertible  into
                           TSA equity.

                  b.       If the transaction does not close by May 28, 1999 and
                           the Note has not been paid,  the Note and any accrued
                           interest will remain payable in full to the Company.

                  c.       If the  transaction  has not closed by May 28,  1999,
                           NCT will forfeit its minority earnings in TSA for the
                           period June 1, 1999 through May 30, 2000.

         NCT  assigns to TSA the sum of $20,685 in escrow and directs the escrow
agent to pay TSA. In addition,  all of the consideration  received by TSA may be
assigned by it to its principal  stockholder,  Top Source Technologies Inc., the
("Company")  and in doing  so,  NCT  shall  have no claim to such  consideration
notwithstanding its status of an owner of 20% of the common stock of TSA.

         This  letter  agreement   amends  the  asset  purchase   agreement  the
("Agreement")  entered into as of August 14, 1998 by and among the Company, TSA,
NCT and Noise  Cancellation  Technologies,  Inc., which Agreement was amended on
October 7, 1998. Except as specifically  provided by the amendment of October 7,
