                               PROSPECTUS SUMMARY

     This summary highlights  certain  information  contained  elsewhere in this
Prospectus.  This  summary  is not  complete  and  does not  contain  all of the
information  that you should  consider  before  investing  in the Common  Stock.
Unless the context  indicates  otherwise,  all references herein to "we" include
Tech Laboratories,  Inc. and its wholly-owned subsidiary,  Tech Logistics, Inc.,
collectively,  and references to "Tech  Laboratories"  or "Tech Logistics" shall
mean  each of such  companies  alone.  You  should  read the  entire  Prospectus
carefully, especially the risks of investing in the Common Stock discussed under
"Risk Factors."

                                   The Company

     We  currently  manufacture  and  sell  various  electrical  and  electronic
components. On April 27, 1999, we acquired from NORDX/CDT, INC., a subsidiary of
Cable Design Technologies Corp., the DynaTraX(TM)  digital matrix switch system,
which is a patented, state-of-the-art,  transparent customer-premise, high-speed
network  switching  system.  We believe that the acquisition of the DynaTraX(TM)
technology will enable us to become a provider of  multi-media,  digital network
distribution  and management  equipment for use in community campus and building
facilities.

     We  feel  our  DynatraX(TM),  all  digital,  high-speed,   customer-premise
networking  technology  will play a large role in helping  developers,  builders
and/or managers of private residential  communities and commercial,  industrial,
educational and hospitality  complexes establish facilities that will distribute
and manage high-speed  digital Internet,  Long Distance and CATV services.  This
technology  permits these users to bypass current  telephone and CATV companies'
"Last Mile"  connection  service,  possibly  allowing them to realize  recurring
revenues and to make their properties more attractive to tenants.

     In  addition  to our  DynaTraX(TM)  technology,  during the last two years,
through  our  subsidiary,  Tech  Logistics,  Inc.,  we have been  marketing  and
manufacturing,  under our exclusive license, an infrared perimeter intrusion and
anti-terrorist  detection system or "IDS".  The IDS was originally  designed for
military  applications,  and we  currently  market  this  product to  government
agencies and private industry for use in nuclear,  industrial, and institutional
installations.

     We have been in business since the 1930s, and in 1947, we were incorporated
in New Jersey.  Our principal  offices are located at 955 Belmont Avenue,  North
Haledon, New Jersey 07508, and our telephone number is (973) 427-5333.

                                  RISK FACTORS

     In  addition  to other  matters  described  in this  document,  prospective
investors should carefully consider the following factors:

We have had a History of Limited Sales and Operating Losses.

     We have had limited sales and have experienced  operating  losses.  For the
years ended  December 31, 1997 and 1998 our sales were  $444,322  and  $552,486,
respectively, and we had net losses of ($274,069) and ($169,104). As of December
31, 1998, we had an accumulated deficit of ($475,476).  We have had limited cash
flow and working capital,  which has restricted our recent operations.  Although
the proceeds of this  Offering  will enable us to implement  our business  plan,
sales  of our  products  must be made at  greatly  increased  volumes  and  with
sufficient  margins to avoid continued losses. No assurance can be given that we
will be able to sell  sufficient  quantities  of our products with margins great
enough to achieve profitability.

We have a Need for Substantial Additional Capital.

     The net  proceeds  from this  offering are  estimated  to be  approximately
$1,900,000,  if only the minimum number of Shares is sold, and $3,400,000 if the
maximum number of Shares is sold. We are significantly  under-capitalized and if
less than all of the  Shares are sold,  we will still be in need of  significant
additional  capital  after  completion  of this  Offering in order to expand our
operations in the manner  contemplated by our management if we are successful in
raising  the  maximum   proceeds  from  this  Offering.   Our  primary   capital
requirements  over the  next 12  months  include  payments  of  trade  payables,
marketing  expenses,  research and  development  and tooling  costs for improved
versions of our existing  products and  development of new products.  We believe
that funds  generated by operations and the proceeds of this  Offering,  if only
the minimum  number of Shares is sold,  will be  sufficient  to sustain  current
operating  levels;  however,  expansion of operations  will need to proceed at a
slower  pace as  operating  funds  permit  unless  we are  able to  arrange  for
financing from other sources.  We currently have no agreements or  understanding
with  respect to  additional  sources of capital or  financing  in  addition  to
amounts raised in this Offering.  We face all of the  difficulties  of a company
that is  undercapitalized.  We lack adequate  capital to expand our  operations,
particularly  if only  the  minimum  number  of  Shares  is  sold.  Accordingly,
investors should be aware of the substantial risk that we may not achieve all of
our proposed business objectives due to a lack of adequate capital.  See "Use of
Proceeds,"  "Management's  Discussion  and Analysis of Financial  Condition  and
Results of Operations," and "Business."

Although We Have Acquired  and/or  Developed  New Products,  We Have Had Limited
Sales of These Products to Date.

     We have,  in the past two years,  entered into a number of  agreements  and
arrangements to acquire, develop and/or market a broader range of products, some
of which incorporate some of our historical products and others of which involve
diversification  into the areas of  security  devices  and  systems  and network
switching systems. Due to our limited resources, we have engaged in only limited
development  and  marketing  of  these  products,  and our  revenues  from  such
activities  have been minimal.  We will require the proceeds of this Offering to
market these products and develop and market new products; however, there can be
no  assurance  that  any of  these  products  will  achieve  significant  market
acceptance or that we will derive significant revenues from these products.


                                       -4-

<PAGE>

The Success of Our Business is  Dependent on Our Ability to Market  DynaTraX(TM)
and Develop and Market Other New Products.

     We believe that the DynaTraX(TM) technology will serve as the basis for new
products in the area of multi-media digital network  distribution and management
equipment for use in campus and building  facilities.  However,  there can be no
assurance that we will  successfully  market such products or develop and market
other new products.  Our success depends upon several factors  including,  among
others, (i) the development of an effective marketing and distribution  network,
(ii) the acceptance of our products by potential users, and (iii) our ability to
support  existing  products  and  develop  and  support  new  products  that are
compatible  with other systems in use by potential  customers and provide useful
features that are user friendly.

     While  we are  not a new  enterprise,  because  we are  in the  process  of
substantially  changing  our  product  line,  we are  encountering  many  of the
problems  faced by a new  enterprise.  You  should be aware of the  difficulties
normally  encountered  by a new  enterprise and the high rate of failure of such
enterprises.  There is no history  upon which to base any  assumption  as to the
likelihood that we will prove successful,  and there can be no assurance that we
will become a viable or profitable business.  The likelihood of our success must
be  considered  in light of the delays,  uncertainties,  difficulties  and risks
inherent  in a new  business,  many of which may be beyond  our  control.  These
include,  but are not limited to,  unanticipated  problems  relating to testing,
manufacturing,  marketing and competition,  development of additional  products,
and  additional  costs  and  expenses  that may  exceed  current  estimates.  In
addition,  there can be no  assurance  that the DynaTraX  products  will receive
commercial acceptance or generate significant revenues. Further, there can be no
assurance  that revenues will  increase  significantly  in the future or that we
will ever achieve profitable operations. See "Business."

Our Market Share  Depends on the  Technical  Superiority  of Our  Products,  Our
7bility to Keep Pace with Technological Changes and Customer Acceptance.

     Our future  success  will  depend in large part on timely  development  and
introduction of new products that provide enhanced  security,  network switching
capabilities  and related  features.  The security  systems and products that we
intend to develop and market represent a significant investment on the part of a
customer. Our products will have to be technologically equivalent or superior to
competing products and cost effective. We will also have to demonstrate that our
products are flexible and can be designed to meet specific and changing customer
needs.  Customers will be seeking to invest in systems that will not be rendered
obsolete or inadequate in the foreseeable  future. In addition,  we will have to
develop and maintain a service capacity for the systems we sell and install.  If
we fail to introduce technologically superior,  cost-competitive products and to
demonstrate  our ability to maintain  and service our  products,  we will not be
able to achieve significant sales.

     We  have  made  a  substantial   investment  in  acquiring  the  technology
underlying the DynaTraX(TM) products and services from NORDX/CDT,  Inc. Although
NORDX/CDT,  Inc. has made some sales of DynaTraX-based  products,  the sales and
operations history of such products has been limited. We cannot be sure that our
DynaTraX(TM)  products  will perform as  anticipated.  There can be no assurance
that any  products  will be  compatible  with other  systems in use by potential
customers,  be capable of being sold,  installed  and  supported  in  commercial
volumes at reasonable prices and costs or be successfully  marketed.  We will be
required  to  create  product  awareness  and  demand,  and  persuade  potential
customers of the advantages of adapting or replacing  existing network switching
systems. We cannot be sure that our products will achieve significant commercial
success or that revenues will equal or exceed the cost of our investment.


                                       -5-

<PAGE>

     In the past we have  experienced,  and we are likely to  experience  in the
future, delays in the development and introduction of products. We cannot assure
you that we will keep pace with the rapid rate of change in security and network
switching  systems  research,  or that our new products will adequately meet the
requirements of the marketplace or achieve market acceptance.

We Have  Limited  Marketing and Sales Capabilities and We Are Dependent on Third
Parties for Marketing Activities.

     Our  operating  results  will  depend to a large  extent on our  ability to
educate  sophisticated  potential customers about the advantages of our products
and to market  our  products  to the  users and  decision  makers  within  those
potential customers. We currently market our existing products primarily through
our catalog. We have very limited marketing capabilities and experience,  and we
need to develop a sales and marketing program and sales  distribution  channels.
We are currently primarily dependent on our President, Bernard M. Ciongoli, who,
because of his other duties as  President,  is only able to devote a part of his
time to such activities,  and our consultant,  MPX Network Solutions,  Inc., for
development and  implementation of our sales and marketing  program,  as well as
for customer  development and contact.  We anticipate that we will depend,  to a
significant extent, on distributors to market and support our products.  We have
not  established  any  such  arrangements  to  date.  The  success  of any  such
relationship  will depend in part upon such parties' own competitive,  marketing
and strategic  considerations,  including the relative advantages of alternative
products being marketed by such persons, and there can be no assurance that such
parties will have the interest or ability to  successfully  market our products.
We cannot be sure that we will be able to arrange  third party  distribution  of
our  products  or that such  arrangements  would  result in  significant  sales.
Further,  we could be dependent for a substantial portion of our sales on one or
a very small  number of  distributors.  In such  event,  the loss of one or more
significant  distributors  could have a material  adverse effect on our business
and financial condition. Our success will depend in great part on our ability to
successfully  implement our  marketing  and sales program and create  sufficient
levels of demand for our products.  There can be no assurance that any marketing
and sales  efforts  undertaken by us or on our behalf will be successful or will
result in any  significant  sales of our  products.  See  "Business -- Marketing
Strategies."

We Have No Assurance as to Protection of Intellectual  Property,  and  We May Be
Dependent on Intellectual Property.

     We have no patent or copyright  protection on our current  products,  other
than the DynatraX(TM) product and technology. Our ability to compete effectively
with other  companies  will  depend,  in part,  on our ability to  maintain  the
proprietary  nature  of  our  technologies.   Other  than  with  regard  to  the
DynatraX(TM) patents, we intend to rely substantially on unpatented  proprietary
information  and  know-how,  and there can be no assurance  that others will not
develop such  information and know-how  independently or otherwise obtain access
to our technology. In addition, we cannot be sure that others will not challenge
the DynatraX(TM)  patents or develop  competing  products that use equivalent or
superior  technology.  Also, it is uncertain whether our proprietary  technology
will not  infringe on other  rights  owned by others and that as a result we may
not be in a position to license such technology at a reasonable cost.

Competition.

     We compete  against a variety of other  concerns,  most of which are larger
and have  greater  financial,  technical  and  marketing  capacities  and  other
resources than we do. See "Business -- Industry."

                                       -6-

<PAGE>

We May Incur Product Liability or Other Liabilities Relating to New Products.

     There is a risk that our current  products may  malfunction  and cause loss
of, or error  in,  data,  loss of man  hours,  damage  to,  or  destruction  of,
equipment  or  delays.  Consequently,  we, as the  manufacturer  of  components,
assemblies,  and  devices  may be  subject  to  claims if such  malfunctions  or
breakdowns  occur.  We are not aware of any past or present  claims  against us.
While we presently do not maintain  product  liability  insurance,  we intend to
obtain such coverage at the completion of this Offering.  We cannot be sure that
such coverage will be available to us on terms we can afford.

     We cannot  predict at this time our potential  liability if customers  make
claims against us asserting that DynatraX(TM), IDS or other new products fail to
function.

Management  Owns a Significant  Interest at a Lower Cost than  Purchasers of the
Shares in this Offering.

     Management  has  acquired a  significant  interest in the Company at a cost
substantially  less  than  that  which  the new  investors  will  pay for  their
shareholdings.  Therefore,  the investors will bear a substantial  risk of loss,
while, as a practical matter,  control of our company is likely to remain in the
hands of management.

The Purchasers Will Incur Immediate Dilution.

     As a purchaser of the shares,  you will incur an immediate  dilution in the
per share book value of their  Common  Stock from $3.50 to $2.82 if the  minimum
number of Shares is sold and from $3.50 to $2.56 if the maximum number of Shares
is sold.  In addition,  the  investors  in the Shares will bear a  substantially
larger portion of the risk of loss of this venture,  while essential  control of
our company will remain with the present shareholders. See "Dilution."

There Is a Very Limited Market for Our Securities.

     There is a very limited market for the Common Stock of the Company,  and no
assurance  can be given that any greater  market will  develop in the future or,
once developed, be maintained, or that the market price of our Common Stock will
not decline. Even if a more active trading market does develop, the market price
of our Common Stock is likely to be highly volatile and could be subject to wide
fluctuations in response to factors such as:

     o    actual or anticipated variations in our quarterly operating results;

     o    announcements of new product or service offerings;

     o    future technological innovations;

     o    new commercial products;

     o    changes in regulation;

     o    changes in financial estimates by securities analysts;

     o    conditions  and  trends  in   the  electrical,  electronic  component,
          security, and network switching industries;

                                       -7-

<PAGE>

     o    changes in the economic  performance and/or market valuations of other
          security and network switching companies; and

     o    general market conditions and other general factors.

     Furthermore,  the stock markets, and in particular,  the OTC Bulletin Board
and NASDAQ stock markets, have experienced extreme price and volume fluctuations
that have particularly  affected the market prices of many technology companies,
and have often been unrelated or disproportionate  to the operating  performance
of such companies.  Additionally,  the market price of our Common Stock could be
adversely affected by losses and other negative news regarding one or more other
companies,  despite  the  fact  that  such  information  is  not  related  to us
specifically.  The trading prices of many technology companies' stocks are at or
near their historical  highs. We cannot assure you that such high trading prices
will be sustained.  These broad market  factors may adversely  affect the market
price of our Common Stock. In addition, general economic,  political, and market
conditions,  such as recessions,  changes in interest  rates,  or  international
currency  fluctuations,  may  adversely  affect the  market  price of our Common
Stock.

The Offering Price of the Shares Was Arbitrarily Determined.

     While  our  shares  trade  on  the  OTC  Bulletin  Board,   the  volume  is
substantially  less than  that  being  offered  in this  Offering,  and does not
reflect  the  market  price  for the  amount  of stock we are  offering  in this
Offering.  The price at which the Shares are being offered has been  arbitrarily
determined  by us, and does not  necessarily  bear any  relationship  to assets,
earnings, book value, or any other ordinary investment criterion.

Shareholders Are Not Entitled to Cumulative Voting.

     Neither  our  Articles  of  Incorporation   nor  our  by-laws  provide  for
cumulative voting.  Since the election of directors and all other questions will
be decided by majority  vote,  except as  otherwise  provided by the Articles of
Incorporation  and the laws of the State of New  Jersey,  the  shareholders  who
purchase the shares offered hereby may not have the power to elect even a single
director and, as a practical matter,  our company will continue to be controlled
by the current  management.  See "Principal  Shareholders"  and  "Description of
Common Stock."

We  Have  Never  Paid  Dividends  and  Are  Unlikely  to  Pay  Dividends  in the
Foreseeable Future.

     We have not paid any  dividends  on our Common  Stock for at least the last
six years  and  intend to follow a policy  of  retaining  earnings,  if any,  to
finance  the  development  and  expansion  of our  business.  Although we do not
envision  payment of dividends,  payment of dividends,  if any, will depend upon
future earnings, financial requirements, and other factors. See "Business."

Dependence Upon Joint Venture Agreement.

     We have  entered  into an Amended  Joint  Marketing  Agreement  (the "Joint
Marketing  Agreement") as of October 1, 1997 with  Elektronik  Apparatebau  GmbH
(EAG), W.T. Sports,  Ltd. and FUA Safety Equipment,  AG and a Confidentialty and
Manufacfuring  Agreement with the same parties and dated the same date, pursuant
to which our company was granted the exclusive  right to manufacture in the U.S.
and market and sell in the U.S., Canada and South America the IDS products.  The
agreements  terminate  on September  30, 2007 subject to automatic  renewals for
successive one-year periods unless either party gives notice of non-renewal. The
Agreement can be terminated  earlier upon a default of any material  obligation.
If the license is terminated,  we would be unable to use EAG's technology in our
perimeter  detection  system products.  Even if the agreements  remain in effect
until September 30, 2007, no assurances can be given that the agreements will be
renewed  or that we will be able to  replace  the IDS  with  other  satisfactory
technology and products.




                                       -8-

<PAGE>


Potential Unavailability of Components; Limited or Single Source of Supply.

     Current inventory purchases are made from OEMs, brokers, and other vendors.
We typically have more than a single source of supply for each part,  component,
or  service,  but from time to time we will have  only a single  supplier  for a
particular part or component.  During the year ended December 31, 1998,  Wiggins
Plastics was our largest supplier with 14.2% of our overall inventory purchases.
These  purchases  were primarily  used in the  manufacture of  electromechanical
switches.  During the year ended December 31, 1997,  Wiggins Plastics  accounted
for 16.8% of our supply of  inventory.  Those  components  were in products that
produced  approximately 25.7% of our revenue for such year. We have no long-term
agreements  with  any  of our  suppliers.  Should  a  supplier,  particularly  a
principal  supplier,  be  unwilling  or  unable to supply  any  inventory  part,
component,  or service  in a timely  manner,  our  business  could be  adversely
affected. In addition, even if such parts or components are available,  shortage
of supply could result in an increase in  procurement  costs which may adversely
affect our profitability.  Additionally,  even though we carry insurance, if our
inventory  is  destroyed  or  damaged  as a result  of a  catastrophe,  it would
materially adversely affect our ability to deliver products to our customers.

We Have No Insurance on the DynatraX(TM) Product Inventory.

     We  currently  do not  have  insurance  on the  DynatraX(TM)  inventory  of
furnished  products and parts purchased from  NORDX/CDT.  These are currently in
possession of NORDX/CDT in Canada awaiting shipment to us. Damage or destruction
of some or all of the inventory would result in a substantial loss to us.

We are  Dependent  on our  Key  Personnel,  and we  will  also  need  Additional
Management and Outside Directors with Business Expertise.

     We are highly  dependent  upon the  efforts of  Bernard  M.  Ciongoli,  our
president and chief executive officer.  The loss of the services of Mr. Ciongoli
would be detrimental to our operations.  We do,  however,  maintain key man life
insurance  on Mr.  Ciongoli  to  compensate  for  any  such  loss,  and  have an
employment agreement with him. See " Management -- Director, Executive Officers,
and Key Consultants."  Expansion of our business may require additional managers
and  employees  with industry  experience.  Competition  for skilled  management
personnel  in the  industry is  intense,  which may make it more  difficult  and
expensive to attract and retain qualified managers and employees.  Additionally,
our board of directors currently consists of Mr. Ciongoli, Mr. Earl M. Bjorndal,
Mr.  Louis  Tomasella,  and Mr.  Carmine O.  Pellose,  Jr. Mr.  Ciongoli and Mr.
Bjorndal are both employed by the company. Expansion of our business will likely
require  additional  non-employee  board  members  with  business  and  industry
experience.

     We do not have directors' and officers' liability insurance. This may limit
our ability to attract qualified non-employee board members.

There are Risks Associated with our Proposed Business Expansion.

     We have plans to expand our  business  operations  in a number of ways over
the  next  12 to 18  months,  provided  that we  receive  the  proceeds  of this
Offering.  We plan to begin the sale of the DynatraX(TM) switch, to complete the
DynatraX(TM) unfinished inventory we

                                       -9-

<PAGE>

     acquired,  and to develop  improved  and  modified  DynatraX(TM)  products.
Additional financing may be necessary to pursue these plans, and there can be no
assurance that such financing will be available. In pursuing business expansion,
we may incur expenses that we cannot recover, and we will be required to expense
certain costs which may  negatively  affect our operating  results.  See "Use of
Proceeds," and "Management's  Discussion and Analysis of Financial Condition and
Results of Operations."

We had a Net Loss in 1998.

     For the year ended  December 31, 1998,  we incurred a net loss of $169,104.
We attribute  such loss to a decrease in sales of our old line of  products,  an
increase  in sales,  engineering,  testing,  and  promotion  expenses of our IDS
product, and other related expenses, as well as consulting and legal expenses in
conjunction with the acquisition of the DynatraX(TM)  product line. There can be
no assurance that we will not generate losses in the future.

There May be Possible Restrictions on Trading Due to Penny Stock Regulation.

     The  Securities  and  Exchange  Commission  has  adopted  Rule 15g-9  which
requires  broker-dealers  who  recommend  "penny  stocks" to persons  other than
established  customers  and  accredited  investors  to  make a  special  written
suitability  determination for the purchaser and receive the purchaser's written
agreement to a transaction prior to sale.

     The  regulations  that  generally  define a "penny  stock" to be any equity
security  that has a market  price of less than  $5.00  per  share,  subject  to
certain exceptions.  Such exceptions include an equity security listed on NASDAQ
and an equity  security  issued by an issuer that has (a) net tangible assets of
at least $2,000,000,  if such issuer has been in continuous  operation for three
years, (b) net tangible assets of at least  $5,000,000,  if such issuer has been
in continuous operation for less than three years, or (c) average annual revenue
of at least  $6,000,000  for the preceding  three years.  Unless an exception is
available,  the  regulations  require  the  delivery,  prior to any  transaction
involving a penny stock,  of a disclosure  schedule  explaining  the penny stock
market and the risks associated therewith.

     After  receipt of the net  proceeds  from this  Offering,  our net tangible
assets  are  expected  to exceed  $2,000,000,  providing  an  exception  to this
regulation even though our share price is below $5.00, so this regulation should
not be applicable,  initially,  to our Shares.  If our net tangible  assets fall
below  $2,000,000  and the  market  price of our  Shares is less than  $5.00 per
Share,  then this  regulation  will apply. If our securities were subject to the
regulations  applicable to penny stocks, the market liquidity for the securities
would be severely affected by limiting the ability of broker-dealers to sell the
securities  and the  ability  of  purchasers  in  this  Offering  to sell  their
securities in the secondary  market.  There is no assurance  that trading in our
securities  will  not be  subject  to  these or  other  regulations  that  would
adversely affect the market for such securities.

     The net  proceeds  from the sale by us of the  minimum  number  of  571,428
Shares (after deducting estimated expenses of this Offering) are estimated to be
$1,900,000.  The net  proceeds  from the  sale by us of the  maximum  number  of
1,000,000 Shares (after deducting expenses of this Offering) are estimated to be
$3,400,000.  The net proceeds will be used by us in approximately  the following
amounts.

     The  foregoing  represents  our best  estimate  of the net  proceeds of the
offering based on current planning and business conditions. The exact allocation
of the  proceeds  for  the  purposes  set  forth  above  and the  timing  of the
expenditures  may vary  significantly  depending  upon the exact amount of funds
raised, the time and cost involved in deploying the funds, and other factors.

     We believe  that the  proceeds  from the  Minimum  Offering  in addition to
revenues from  operations will be sufficient to fund our operations for the next
12 months,  although  such  development  would be at a reduced  pace than if the
Maximum Offering proceeds were received. If an amount less than Maximum Offering
is raised,  we may be required to delay,  scale back, or eliminate  parts of our
development plan or obtain funds through additional  financing,  including loans
or  offerings  of  our   securities.   We  presently   have  no   agreements  or
understandings with respect to any future financing or loan agreements.

                                    DILUTION

     Purchasers of the Shares will experience immediate and substantial dilution
in the value of their Shares after purchase.  Dilution represents the difference
between the initial public offering price per share paid by the purchaser in the
offering and the net tangible book value per share  immediately after completion
of the offering.  Net tangible book value per share  represents the net tangible
assets of our  company  (total  assets less total  liabilities),  divided by the
number of shares of Common Stock  outstanding upon closing of the offering.  Our
net tangible book value (actual) at March 31, 1999 (unaudited),  was $899,911 or
$.25 per common  share.  Taking into account the issuance of (i) 443,617  shares
after March 31, 1999 and (ii) 571,428 common shares for  $2,000,000  after March
31,  1999,  and the sale of the shares  and the  receipt  of the  estimated  net
proceeds, the pro forma net tangible book value after March 31, 1999, would have
been $2,799,911 or $.68 per common share if only the minimum number of Shares is
sold, and $4,299,911 or $.94 per common share if the maximum number of Shares is
sold. This  represents an immediate  increase in net tangible book value of $.43
per  common  share  (minimum  offering)  and $.69 per common  share (at  maximum
offering) to the  existing  shareholders  and an immediate  dilution of $.69 per
common share (minimum  offering) and $.94 per common share (maximum offering) to
persons purchasing Shares in this Offering. The following table illustrates this
per share dilution:

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                              RESULTS OF OPERATION

General

     We were  incorporated  in 1947 as a New Jersey  corporation.  Our focus has
historically been the design, manufacture, and sale of rotary switches. Switches
have been a  significant  part of our  revenue  for five  decades.  In 1995,  to
augment revenues, we sought business in transformers and contract manufacturing.
In 1998, we made a shift to new product  development.  In 1998, we also made our
first  sales  of the IDS  product,  and in  April  of  1999,  we  completed  the
acquisition of the DynaTraX(TM) switch and technology. We will continue to focus
on IDS and DynaTraX(TM) sales and development of additional products using these
technologies.

     The following  table sets forth the  components of our revenues for each of
our major business  activities in 1996,  1997, and 1998 and for the three months
ended March 31, 1998 and 1999 and their approximate  percentage  contribution to
revenues for the period indicated:

     As the foregoing  reflects,  there was a  significant  decrease in sales of
rotary  switches  and  contract  manufacturing,  due to a shift  to new  product
development  and  sales.  There  were no sales of the new IDS in 1997.  In 1998,
sales of the IDS were $254,900.

     The following  table sets forth the percentages of gross profit for each of
our major  business  activities in 1997 and 1998, and for the three months ended
March 31, 1998 and 1999:

     We have begun to shift out of the subcontracting  and transformer  business
which provides low gross profit margins, for higher gross profit margin sales of
IDS and other new products.  While rotary  switches  produce high gross profits,
demand for rotary switches is low.

     We have gradually shifted our product offering from less profitable to more
profitable proprietary products.

Results of Operations

Three Months Ended March 31, 1999, Compared to Three Months Ended March 31, 1998
- -- Unaudited.

     Sales  were  $59,714  for the first  three  months of 1999 as  compared  to
$86,160 for the three  months  ended March 31,  1998.  The  decrease  was due to
limited marketing efforts and the lack of new product introductions.

     Cost of sales of $40,008 for the three months ended March 31, 1999 compared
to $86,591 for the same period in 1998 decreased significantly due to reductions
in manufacturing costs, efficiencies, and reduction of manufacturing staff.

     Selling,  general, and administrative  expenses decreased by $29,642 or 31%
in the first  quarter  of 1999 as  compared  to the prior  period in 1998  which
resulted  from higher than normal  expenses in 1998 and cost  reduction  efforts
implemented in the fourth quarter of 1998. Selling,  general, and administrative
expenses  would be in line with  1998  after  eliminating  the  higher  expenses
incurred in 1998.

     Losses from  operations of $44,937 in the first quarter of 1999 declined by
$49,779 or 53%  compared to losses of $94,716  for the prior  period as a direct
result of reduced costs and lower selling, general, and administrative expenses.

1998 Compared to 1997.

     Sales increased 24% from $444,322 in 1997 to $552,486 in 1998. This was due
to an increase in sales of the Intrusion Detection System (IDS).

     Cost of sales  decreased  16% from $446,457 in 1997 to $386,425 in 1998 due
to an increase in sales of new products.

     Selling,  general  and  administrative  expenses,  including  depreciation,
increased 24% from  $265,104 in 1997 to $329,849 in 1998 due to increased  sales
efforts,  engineering,  testing, and promotion of new product introductions,  as
well as consulting, legal, and other expenses in connection with the acquisition
of the DynaTraX(TM) product line.

     Income (loss) from operations decreased 39% from a loss of $267,239 in 1997
to a loss  of  $163,788  in 1998  due to  higher  gross  profit  margins  on new
products.

     Interest  expense  decreased  negligibly  from  $6,996 in 1997 to $6,970 in
1998.

1997 Compared to 1996

     Sales  decreased  31.3% from  $647,015 in 1996 to $444,322 in 1997 due to a
decrease in subcontracting activity.

     Cost of sales increased 32.4% from $337,269 in 1996 to $446,457 in 1997 due
to fixed overhead.

     Selling,  general  and  administrative  expenses,  including  depreciation,
increased slightly from $257,764 in 1996 to $265,104 in 1997.

     We had income of $51,982 for 1996 as compared to a loss of  ($267,239)  for
1997 due to lower sales from subcontracting activity.

     Interest expense increased 119% from $3,188 in 1996 to $6,996 in 1997.

Liquidity and Capital Resources.

     During the years ended  December 31, 1997 and 1998 and for the three months
ended March 31, 1998 and 1999 we have had difficulty meeting our working capital
requirements which was a result of lower sales,  limited marketing efforts,  and
continued losses from  operations.  During the years ended December 31, 1997 and
1998, we completed sales of our common stock which raised approximately $407,000
in 1997 and  $603,716  in 1998.  During  calendar  1999 we raised an  additional
$250,000  for the  acquisition  of the  DynaTraX(TM)  assets  and an  additional
$200,000 for working capital.

     During  1998 we sold our  first IDS  products  to the U.S.  government  Los
Alamos  facility.  Continued  sales will,  however,  be dependent upon sustained
marketing efforts.  Bacause sales from our historical lines of products have not
in the past, and are not in the future expected to generate  sufficient  revenue
to support our  product  development  and  marketing  and sales  efforts for our
DynaTraX(TM) and IDS products,  we will be required to meet our capital needs to
finance our business plan through the sale of our shares of common stock in this
offering.  In the event we are unable to complete  this offering or we sell less
than the maximum number of shares offered hereby, we will be required to curtail
the implementation of our business plan.

                                    BUSINESS

General

     Tech  Laboratories,   Inc.  ("Tech  Labs"  or  the  "Company"),  which  was
incorporated in 1947,  currently  manufactures and sells various  electrical and
electronic  components.  On April 27, 1999, we completed the  acquisition of the
DynaTraX(TM)  high-speed digital switch matrix system, a patented,  state of the
art,  transparent, customer-premise,  high-speed  network  switching  system. We
believe that the  acquisition of the  DynaTraX(TM)  technology will enable us to
become a provider of multi-media  digital  network  distribution  and management
equipment for use in campus and building facilities.

     In  addition,  during  the last two years,  through  our  subsidiary,  Tech
Logistics,  Inc., we have been marketing and  manufacturing  under our exclusive
license, an infrared perimeter intrusion and anti-terrorist  detection system or
"IDS."  The  IDS was  originally  designed  for  military  applications,  and we
currently  market this product to government  agencies and private  industry for
use in nuclear, industrial, and institutional installations.

Historical Business

     We manufacture and sell standard and customized switches,  transformers and
test  equipment.  In  addition,  we act as a  contract  manufacturer  for  other
companies  and produce on an OEM basis  electronic  and  electrical  assemblies,
printed circuit board assemblies,  cable and harness  assemblies and specialized
electronic  equipment.  Approximately  15% of our products are  manufactured for
military applications.

     Our  switches are  primarily  incorporated  in  electronic  and  electrical
devices,  test field  engineering,  manufacturing and quality control equipment,
and are standardized and custom-made.  Transformers are devices for converting a
varying  current from one voltage to another and may  increase the voltage.  Our
historic customer base for transformers has been the elevator industry.

     Our contract manufacturing activities have included fabrication of computer
boards and assembly of cables and harnesses.  In addition, we have manufactured,
on an OEM basis,  such products as infrared  beam  perimeter  security  devices,
microprocessor  based  machine  controls,  test  instruments  for  ophthalmology
products,  test instruments for  manufacturers of integrated  circuits,  control
components for photo-lithographic products,  high-power control panels and power
distribution control panels.

     We have also expanded our product lines by manufacturing  test equipment in
which  switches are a key  component.  We have designed test  instruments in the
fields of resistance,  inductance and capacitance decade substitution that serve
as calibration and design aids for engineers.

     We have also  developed a new line of decade  resistance,  capacitance  and
inductance   substituters,   utilizing  our  highly  reliable  rotary  switches.
Prototypes for these  products have been made and evaluated,  and the tooling to
produce these products has been completed. We intend to market our new line over
the Internet,  as well as through our distribution and outside sales agents. Our
website is currently on-line. Our website address is www.techlabsinc.com.

     We have,  in the past two years,  entered into a number of  agreements  and
arrangements to develop and/or market a broader range of products, some of which
incorporate  some  of our  historical  products  and  others  of  which  involve
diversification  into the areas of  security  devices  and  systems  and network
switching systems. Due to our limited resources, we have only engaged in limited
development  and  marketing  of  these  products,  and our  revenues  from  such
activities have been minimal.

                                      -19-

<PAGE>

We will  require the  proceeds of this  Offering to market  these  products  and
develop  additional  products,  and there can be no assurance  that any of these
products  will  achieve  significant  market  acceptance  or that we can  derive
significant revenues from these products.

The DynaTraX(TM) Assets Acquisition

     On April 27, 1999, we completed the acquisition of the DynaTraX(TM) digital
switch  matrix  system,  a  state-of-the-art,   transparent   customer  premise,
high-speed network switching system from NORDX/CDT,  INC., a subsidiary of Cable
Design  Technologies  Corp. In connection  with the  acquisition of DynaTraX(TM)
technology,  we  acquired  certain  inventory,   customer  and  supplier  lists,
marketing and promotional materials, patents and patent applications,  and other
equipment related to the DynaTraX(TM)  product.  We believe that the acquisition
of  the  DynaTraX(TM)  technology  will  enable  us  to  become  a  provider  of
multi-media  digital network  distribution  and management  equipment for use in
campus and building facilities.

     We  believe  that  there is a rapidly  growing  marketplace  for  "digital"
multi-media  (internet,  high-speed data,  digital voice and video)  information
equipment  and systems.  We intend to use the  DynaTraX(TM)  unique  high-speed,
transparent  digital  cross-connect  matrix  to  produce  a  line  of  standard,
universal  firmware,  configurable  digital network  distribution and management
equipment  that  OEM's  and/or  Value-Added-Resellers  will  be able to use as a
platform they can custom  configure,  through  software,  to supply a variety of
industry and customer-specific applications and functions. There is no assurance
that we will be able to develop or successfully  market these proposed products.
We will need the funds from this  Offering  to develop  and market our  existing
DynaTraX(TM)  products,  as well as developing  new products  incorporating  the
DynaTraX(TM)  technology.  See "Risk  Factors."  In the long term,  we intend to
build industry recognition for producing private,  customer-premise  (community,
commercial,  educational and hospitality complexes,  and residential buildings),
high-speed  Internet,  Long  Distance,  Intranet  information  distribution  and
management switching systems.

     We believe  the future  trend in  communications  is  reselling  local loop
services using new digital  transmission  technology and equipment to get around
the present "de facto monopoly" telephone and CATV companies maintain over local
connection and distribution services.

     We  feel  our  DynaTraX(TM),  all  digital,  high-speed,   customer-premise
networking  technology  will play a large role in helping  developers,  builders
and/or managers of private residential  communities and commercial,  industrial,
educational and hospitality  complexes establish facilities that will distribute
and manage high-speed  digital Internet,  Long Distance and CATV services.  This
technology  permits these users to bypass current  telephone and CATV companies'
"Last Mile" connection service,  possibly allowing them to increase rents and to
make their properties more attractive to tenants.

Industry

DynaTraX(TM) Networking Management and Maintenance Technology

     Our DynaTraX(TM)  product is proposed to be sold in the multi-media digital
network  distribution and management  equipment industry.  The growth in digital
networks is clear as is the cost in supporting and  maintaining  these networks.
We have  recently  completed  the purchase of the  DynaTraX(TM)  technology  and
inventory and initially  intend to market the product in the eastern  portion of
the United States with expansion to other markets over time.  There are at least
four  companies that have products that compete with the  DynaTraX(TM)  product.
However,  we believe none of these  competitors  offer a product with all of the
features or capabilities of the DynaTraX(TM) product.


                                      -20-

<PAGE>

     We expect that competition in the sale of our DynaTraX(TM)  product will be
on the basis of price, features,  service and technical support.  Pricing of our
products is based upon obtaining a margin above cost of  production.  The margin
we will accept varies with quantity and the channels of distribution.

     We believe that our DynaTraX(TM)  product offers a faster switch and a much
smaller  port size than any  competing  product and is not limited to a specific
type of network as with some competing products.

     Competition for network management products comes in several forms and from
several  different  groups.  One group of  competitors  is the internal staff of
large  organizations  who have built up a business  unit to manage and  maintain
their  networks  and have a vested  interest  in  maintaining  the  status  quo.
However,  we believe the need for  businesses  to reduce costs works in favor of
implementing  cost  saving  technologies  such as the  DynaTraX(TM)  technology.
Another group of competitors  which produce  products to manage and maintain the
network  physical  layer  consists  of  NHC,  RIT and  Cyteck.  Of  these  three
companies,  NHC is the only one that offers a transparent high-speed switch. The
NHC switch is not as fast as our  DynaTraX(TM)  product and much smaller in port
size. In addition,  V-LAN  switching can be regarded as a competing  technology.
However, V-LAN switching is limited to a specific type of network (Ethernet) and
not able to support many tasks  associated  with  rearranging  network  physical
layer connections, testing circuits, managing and maintaining end-to-end network
configuration and  asset/inventory  records. We regard V-LAN as complementary to
DynaTraX(TM)  circuit  switching  since they can work together to provide a more
comprehensive network management/maintenance  solution. The four competitors all
have greater financial and other resources.

Infrared Intrusion Detection System ("IDS")

     In April 1997, we formed Tech Logistics,  Inc., a joint venture  subsidiary
owned at that time 80% by our  company  and 20% by  Carmine O.  Pellose,  Jr., a
director  of our  company and  president  of  International  Logistic,  Inc.,  a
privately  owned  company  that  distributes   police,   security,   safety  and
communication  security devices. In May 1998, we acquired Mr. Pellose's interest
in Tech  Logistics.  The IDS, which is an active  infrared sensor system able to
detect  intrusions by humans or vehicles into  protected  areas,  was originally
designed for military  applications.  We have begun  marketing it to  government
agencies and private industry for use in nuclear,  industrial, and institutional
installations.  We have also begun to manufacture and market products  currently
sold by International Logistics Inc., as well as new security,  police training,
bomb detection and disposal  equipment,  anti-terrorism  countermeasures and lie
detection  devices.  New devices are intended to include  hand-held  letter bomb
detectors,  hand-held weapons detectors, video surveillance equipment as well as
integrated audio-visual surveillance vehicles for government and police use.

     We have entered into an Amended and Restated Joint Marketing  Agreement and
a  Confidentiality  and  Manufacturing  Agreement  as of  October  1,  1997 with
Elekronik Apparatebau GmbH (EAG), W.T. Sports, Ltd. and FUA Safety Equipment, AG
(FUA),  pursuant  to which our  company  was  granted an  exclusive  right until
September 30, 2007 to manufacture and sell in the U.S., Canada and South America
the IDS products.  The  agreements  provide that gross pre-tax  profits shall be
calculated  according to GAAP and shall be distributed  quarterly in arrears 70%
to our company and 30% to FUA until March 31, 2001. Thereafter,  until September
30,  2007 the  agreements  provide  that any pre-tax net profit in excess of 16%
shall be  distributed  70% to our company and 30% to FUA. In  addition,  we will
also pay FUA a royalty of 5% of the cost of any IDS products we manufacture  and
sell. We also intend to market metal detection equipment manufactured by EAG for
use  in  security  and  industrial  applications,  such  as  walk-through  metal
detectors and hand-held metal detectors.

     Our  IDS  products  are  being  sold  in the  security  and  anti-terrorist
industry. We believe this is a growing industry and that terrorist incidents and
security breaches serve to increase the demand for products in this industry. We
have recently completed the sale of an IDS to Los Alamos National

                                      -21-

<PAGE>

Laboratories.

     This   industry   has  a  number  of  different   competing   products  and
technologies. Competition in the industry is partly based on price and partly on
other factors such as effectiveness of a product in the field, acceptable levels
of false alarms for a given application,  and service.  We are marketing the IDS
product for global  distribution.  We have a number of  competitors  for the IDS
products offering  competitive  technology,  many of whom have greater financial
and other resources. We have received "first look" approval for the IDS from the
U.S. Military for inclusion in their Tactical  Automated  Security System (TASS)
program  which is a $500  million  program to thwart  enemy  attacks on critical
military  installations  throughout the world.  Pricing of our products is based
upon  obtaining  a margin  above cost of  production.  The margin we will accept
varies with quantity and the channels of distribution.

Switches, Transformers and Test Equipment

     We  sell  our  switch,  transformer  and  test  equipment  products  in the
electronics and electrical industries,  primarily as a contract manufacturer for
other  companies  or for  inclusion in OEM  products.  We market our products in
these industries in the United States.  This is a mature market.  Competition is
on the  basis of price  and  service.  Pricing  of our  products  is based  upon
obtaining a margin above cost of  production.  The margin we will accept  varies
with quantity and the channels of distribution. We have many competitors in this
market  who are able to  produce  similar  quality  products,  many of whom have
greater financial and other resources than we do.

Marketing Strategies

     Marketing.   We  plan  to  implement  a  three-pronged   marketing  program
consisting of:

     (i)  Industry announcements and presentations through business and industry
          trade groups;

     (ii) Establishing  relationships  with several  industry  recommenders  and
          specifiers,  who are  consultants  and  engineering  companies to help
          present our cable  management and network  physical layer solutions to
          the end-users and their contract management or system integrators; and

    (iii) A promotional  campaign of ads, mailings,  and on-line Web site media,
          targeted at the end-user  communications  managers,  their consultants
          and advisers.

     Initially,  we will  focus  on a  limited  geographical  area -- the  large
communication/computer centers in the eastern part of the United States. We plan
to divide this area into four sales regions:  (i) New England  states;  (ii) New
York metropolitan  area; (iii)  Mid-Atlantic/Washington  DC area; and (iv) South
East Coast  states.  We will  quickly set up several  regional  representatives,
sales agents,  and/or certified value added resellers (VARs) in each of the four
regions.  Our plan is to have one representative and, initially,  up to two VARs
for each region.  Whenever  possible,  we plan to use former  NORDX/CDT  trained
sales agents and certified VARs.

     Sales  representatives  will be  commissioned  sales  agents.  VARs will be
system  integrators  who will purchase  DynaTraX(TM)  products at a volume based
discount  price for resale as part of a  turn-key  (design,  install,  maintain)
service.

     In the long term,  we plan to expand on the  initial  program by opening up
additional sales areas in the country and overseas. We contemplate doing this by
adding regional  representatives or agents, or through current VAR organizations
that have a national presence.


                                      -22-

<PAGE>

     In the  established  East  Coast  area,  we intend to set up three  company
regional  sales/service  centers:  (i) Massachusetts;  (ii) Washington,  DC; and
(iii)  Florida.  We will  repeat the  process in the other  areas as they become
established.

     We  plan to use our  company's  sales/service  centers  to  introduce  new,
enhanced versions of the DynaTraX(TM)  system and to provide territory  customer
support services. We also plan to set up a separate marketing campaign and sales
operations  to  build  markets  for our  expanded  high-speed,  customer-premise
DynaTraX(TM) gateway networking switch.

     In  addition,  working  with  VARs,  we will focus on  providing  turn-key,
private  customer-premise  digital gateway exchange  networking systems. We will
target real estate  developers,  builders and/or owners of private  communities,
commercial community retail complexes and shared rental buildings to enable them
to control and resell  Internet,  Long Distance,  CATV, and building  automation
information services going into and out of their private facilities.

     Although we believe that we can be  profitable by the third quarter of 1999
from the  increased  sales of our IDS products  and sales of the newly  acquired
DynaTraX(TM)  completed  inventory,  our  profitability  is  subject to both the
successful and timely  implementation of our business plan and market acceptance
of our new products.  All research and development of our IDS products have been
expensed and we have received  preliminary  approval from the U.S. Air Force for
inclusion of the IDS products in its TASS program.

     Our plan to become profitable  included the acquisition of the DynaTraX(TM)
product  in April  1999  and to sell  the  finished  DynaTraX(TM)  inventory  we
acquired.

     Because we have incurred  substantially  all our  anticipated  research and
development  costs with respect to our IDS product and have had it preliminarily
approved  by the U.S.  Military  for  inclusion  in the TASS  program,  and have
completed  the purchase of the  DynaTraX(TM)  switch,  technology  and marketing
materials,  upon completion of this offering,  we believe we will have the funds
necessary to market our products and achieve  profitability.  Our  profitability
will be delayed if we are not able to sell our products as we have  anticipated.
We believe we are  raising  sufficient  funds with this  offering to achieve the
sales necessary to become profitable and to provide  sufficient  liquidity until
such time as we become profitable. In the event that sales and profitability are
delayed to the point beyond that anticipated and liquidity is impacted, we would
reduce or defer operating expenses,  such as expenses to finish work in progress
relating  to  the  DynaTraX(TM)   inventory  and  research  and  development  of
additional DynaTraX(TM) products.

Order Backlog

     The backlog of written  firm  orders for our  products  and  services as of
March 31, 1999, was as follows:

          As of March 31, 1999: $151,226

          As of March 31, 1998: $165,245

Patents

     In connection with our acquisition of the DynatraX(TM)  assets, we acquired
certain patents and pending patent applications. While a patent has been granted
in Great Britain,  our patent applications in the U.S., Europe and elsewhere are
subject to review in those  jurisdictions.  There can be no assurance that these
patents  will be  granted  and even if  granted  may  afford  us  limited  or no
protection,  depending  upon the  nature of  competing  technology  and upon our
ability to defend our intellectual property rights.

Recent Financing

     In April 1999, we completed our financing plan for, among other things, the
acquisition of  DynaTraX(TM)technology  and related assets  pursuant to which we
raised $250,000 from the sale of 278,572 shares.  Subsequently,  in May 1999, we
raised an additional $200,000 for general working capital purposes from the sale
of 90,045 shares.

<PAGE>

Employees

     As of  March  31,  1999,  we  had 11  full-time  employees,  including  our
officers,  seven of whom were engaged in manufacturing,  one in repair services,
one in administration and financial control, one in engineering and research and
development, and one in marketing and sales.

Facilities; Manufacturing

     Our  manufacturing  facility is located in North Haledon,  New Jersey.  Our
primary  manufacturing  and office  facility  is a  one-story  building  that is
adequate  for our current  needs.  We lease this  facility of 8,000 square feet,
from a non-affiliated  person,  under a lease that ends in May, 2001. The annual
base rent is $48,000  and  includes  property  taxes and other  adjustments.  We
believe our premises  are  adequate  for our current  needs and that if and when
additional space is required, it would be available on acceptable terms.

     We are an  integrated  manufacturer  and,  accordingly,  except for plastic
moldings and extrusions,  produce nearly all major  subassemblies and components
of our devices from raw materials.  We purchase certain  components from outside
sources and maintain an in-house,  light machine shop allowing  fabrication of a
variety of metal parts and castings, complete tool room for making and repairing
dies, a stamping shop and an assembly shop with light assembly presses. Our test
lab  checks  and tests our  products  at  various  stages of  assembly  and each
finished product undergoes a complete test prior to shipment.

     We anticipate that we will either manufacture any new products ourselves or
subcontract their  manufacture,  in whole or in part, to others. We believe that
personnel,  equipment,  and/or  subcontractors  will be readily available as and
when needed.

     We offer warranties on all our current products,  including parts and labor
for one year.

     We have limited  research and development  facilities and currently  employ
one (1) engineer.

Litigation

     We are involved in a lawsuit  arising from a letter of intent relating to a
small potential  transaction we did not complete  because we believed there were
misrepresentations  made to us.  We  believe  that the  outcome  is likely to be
favorable, but that our maximum liability if we do not prevail would be $30,000.

     We do not  have  employment  agreements  with  any  other officer or  other
employee,  and no officer had received compensation in excess of $100,000 in any
recent fiscal year. Our directors are not presently compensated.

Consultants

     We have  entered into a consulting  agreement  with MPX Network  Solutions,
Inc.  ("MPX").  The term of the  agreement is for one year expiring on March 14,
2000,  renewable for an additional one year period.  MPX will provide consulting
services in the areas of marketing, customer relations and strategic and product
development planning,  particularly with regard to communications  products. MPX
will   receive  an  annual  fee  of  $52,000   and   commissions   on  sales  of
telecommunications  products during the term of the agreement ranging from 3% of
the first  $1,000,000 of the net sale prices to 1/2% of the net sale prices over
$4,000,000.  MPX will also  receive  50,000  shares of Common  Stock and will be
issued  options to purchase up to 50,000 shares of Common  Stock,  at a purchase
price of $1.25 per share, depending on net sales of telecommunications  products
during the initial term and the extension term of the agreement.  These services
will be provided on an as needed basis,  primarily by MPX's  President,  Mr. Sal
Grisafi.

     We have also entered into a consulting  agreement with Scott Coby ("Coby").
Under the terms of the agreement,  the consultant will provide certain marketing
and financial services. In consideration for entering into the agreement,  which
has an initial term of two years, our company issued to the consultant a warrant
to purchase  50,000  shares of Common Stock at $1.85 per share  exercisable  for
five (5) years, and an additional  warrant (the "Second Warrant") to purchase up
to 200,000  shares of Common Stock at $3.50 per share  exercisable  for five (5)
years,  the Second Warrant to vest in increments of 25,000 shares each for sales
of  $250,000  or  more  of our  company's  product  to  purchasers  obtained  by
consultant within the initial two (2) year term of the Consulting Agreement. The
shares underlying the warrants have certain registration rights.

     We have also entered into a consulting agreement dated March 10, 1999, with
Mint Corporation,  a New York corporation ("Mint"), to provide certain financial
and business  consulting  services,  which include  assisting our  management in
developing  its  business  plan,  introducing  our  company  to  members  of the
financial community,  and assisting our company in its financial planning. Under
its  consulting  agreement  which may be terminated by our company upon ten (10)
days'  prior  written  notice,  we agreed to (i) pay  consultant  up to  100,000
shares, 25,000 of which shares have been earned, and (ii) to grant to consultant
an option to purchase up to 200,000  shares of common stock,  such options to be
exercisable  to  purchase  100,000  shares at $1.25 per  share  and  options  to
purchase  100,000  shares at $1.75 per share.  The options  vests in full if the
agreement has not been  terminated  by our company  prior to July 10, 1999.  The
shares underlying the options have certain registration rights.

Stock Option Plan

     On December  11, 1996,  the Board of Directors  adopted a stock option plan
for officers, directors, and other key employees. A total of 450,000 shares were
set aside for this purpose,  and options for an aggregate of 190,000 shares have
been granted at an exercise price of $.50 per share.

                              CERTAIN TRANSACTIONS

     The information set forth herein describes certain transactions between the
Company and certain affiliated  parties.  Future  transactions,  if any, must be

     On December 11, 1996, we agreed to  compensate  our  President,  Bernard M.
Ciongoli,  and our Vice  President,  Earl M. Bjorndal,  for unpaid salary earned
during 1996 in the form of Common Stock.  Mr. Ciongoli  received  280,000 shares

Bjorndal  received  160,000  shares  for unpaid  salary  earned in the amount of
$8,000 at $0.05 per share.

     In December,  1996, we issued to Louis  Tomasella  100,000 shares of Common
Stock for consulting services.

     In April, 1997, we formed Tech Logistics,  Inc., a joint venture subsidiary
with  Carmine  O.  Pellose,  Jr.  to  market  security  devices  distributed  by
International Logistics, Inc., a private-owned company, of which Mr. Pellose was
the President and principal  shareholder.  Mr.  Pellose became a director of the
Company at that time.  In May 1998, we acquired Mr.  Pellose's  interest in Tech
Logistics,  Inc. for 25,000 shares of our Common  Stock.  See "Business -- Other
Recent Developments."

                              PLAN OF DISTRIBUTION

     We will receive proceeds from the sale of the shares, aggregating a maximum
of  $3,500,000  if such shares are sold. We will not receive the proceeds of any
sale of the  securities by the Selling  Securityholders.  We will pay all of the
expenses incident to the registration of the securities (including  registration
pursuant  to the  securities  laws of certain  states)  other than  commissions,
expenses, reimbursements, and discounts of underwriters, dealers, and agents, if
any, made pursuant to the sale by the Selling Securityholders.

Minimum Offering and Escrow Account

     All funds  received  by us with  respect  to the sale of the first  571,428
shares will be deposited by us at a federally  funded  national bank. If 571,428
shares are not sold within ninety (90) days  following the effective date of the
registration  statement of which this  Prospectus  is a part,  the offering will
automatically terminate unless extended for up to an additional ninety (90) days
in the sole  discretion  of the Company and all funds  received from the sale of
the Shares will be returned to

                                      -28-

<PAGE>

     the  purchasers  thereof  with  interest,  at the same  rate as paid by the
escrow  bank.  At the time that  571,428  shares  have  been  sold (the  Minimum
Offering)  prior to the  90-day  period (as the same may be  extended),  we will
release the funds from the escrow  account for deposit into the working  account
of our  company.  Although we will  continue to sell the  offering to attempt to
reach the Maximum Offering (1,000,000 Shares),  such released funds will be used
at that time by our company as described herein.

     We may  use  one or  more  member  firms  of the  National  Association  of
Securities Dealers,  Inc. to sell the shares. As of the date hereof, we have not
entered into any agreements or arrangements  for the sale of the shares with any
broker,  dealer,  or sales  agent.  Any  underwriters,  dealers,  or agents  who
participate in the distribution of the Shares may be deemed to be "underwriters"
under  the  Securities  Act,  and any  discounts,  commissions,  or  concessions
received  by any such  underwriters,  dealers,  or  agents  may be  deemed to be
underwriting  discounts and commissions  under the Securities Act. We anticipate
that we will pay a commission or underwriting  fee to such brokers or dealers of
no more than 10%.

     If, at some time, our company meets the requirements of the NASDAQ SmallCap
Market, it will apply for listing thereon.  If it should be accepted for listing
thereon,   then  certain  underwriters  may  engage  in  passive  market  making
transactions  in our  company's  Common  Stock in  accordance  with  Rule 103 of
Regulation M.

     In order to comply with the applicable  securities laws, if any, of certain
states, the securities will be offered or sold in such states through registered
or licensed brokers or dealers in those states. In addition,  in certain states,
the  securities  may not be offered or sold unless they have been  registered or
qualified  for sale in such states or an  exemption  from such  registration  or
qualification requirement is available and with which we have complied.

Limited State Registration

     We anticipate that we will primarily sell the shares in a limited number of
states,  depending  on the location and  registration  of any selling  broker or
dealer that it locates.  We will initially seek to qualify or register the sales
of the shares in the states of New York,  New Jersey,  Connecticut,  California,
Florida,  Illinois,  and Nevada. We will not accept subscriptions from investors
resident in other states unless we effect a  registration  therein or determines
that no such registration is required.

Sales by the Selling Securityholders

     The Selling  Securityholders  may be sold to  purchasers  from time to time
directly by and subject to the  discretion of the Selling  Securityholders.  The
Selling  Securityholders may, from time to time, offer their securities for sale
through  underwriters,  dealers, or agents, who may receive  compensation in the
form of underwriting  discounts,  concessions,  or commissions  from the Selling
Securityholders and/or the purchasers of the securities for whom they may act as
agents. Any underwriters, dealers, or agents who participate in the distribution
of the securities may be deemed to be "underwriters" under the 1933 Act, and any
discounts,  commissions,  or  concessions  received  by any  such  underwriters,
dealers,  or agents may be deemed to be  underwriting  discounts and commissions
under the 1933 Act. The securities  sold by the Selling  Securityholders  may be
sold from time to time in one or more  transactions at an offering price that is
fixed or that may vary from  transaction to transaction  depending upon the time
of sale or at prices otherwise  negotiated at the time of sale. Such prices will
be determined by the Selling Securityholders or by agreement between the Selling
Securityholders and any underwriters.

                                      -29-

<PAGE>

     Any underwriters, dealers, or agents who participate in the distribution of
the securities may be deemed to be "underwriters"  under the Securities Act, and
any discounts,  commissions,  or concessions  received by any such underwriters,
dealers,  or agents may be deemed to be  underwriting  discounts and commissions
under the Securities Act.

     At the time a  particular  offer is made by or on the behalf of the Selling
Securityholders,  a prospectus, including any necessary supplement thereto, will
be  distributed  which will set forth the  number of shares of Common  Stock and
other  securities  being offered,  and the terms of the offering,  including the
name or names of any underwriters,  dealers,  or agents, the purchase price paid
by any  underwriter for the shares  purchased from the Selling  Securityholders,
any discounts,  commissions and other items  constituting  compensation from the
Selling  Securityholders,  any discounts,  commissions,  or concessions allowed,
reallowed, or paid to dealers, and the proposed selling price to the public.

Use of a Broker-Dealer

     If we determine to use a broker-dealer, such broker-dealer must be a member
in good standing of the National  Association  of Securities  Dealers,  Inc. and
registered, if required, to conduct sales in those states in which it would sell
the  shares.  We  anticipate  that we would  not pay in excess of 10% as a sales
commission  for any sales of the  shares.  If a  broker-dealer  were to sell the
shares,  it  is  likely  that  such  broker-dealer  would  be  deemed  to  be an
underwriter  of the securities as defined in Section 2(11) of the Securities Act
and we would be required to obtain a  no-objection  position  from the  National
Association  of  Securities   Dealers,   Inc.  regarding  the  underwriting  and
compensation   terms  entered  into  between  our  company  and  such  potential
broker-dealer.  In  addition,  we would  be  required  to file a  post-effective
amendment to the  registration  statement of which this  Prospectus is a part to
disclose the name of such selling  broker-dealer and the agreed underwriting and
compensation  terms. In order to comply with the applicable  securities laws, if
any, of certain  states,  the securities  will be offered or sold in such states
through registered or licensed brokers or dealers in those states.

     Pursuant  to  Regulation  M of the  General  Rules and  Regulations  of the
Securities and Exchange  Commission,  any person  engaged in a  distribution  of
securities,   including  on  behalf  of  a  selling   securityholder,   may  not
simultaneously  bid for,  purchase  or  attempt to induce any person to bid for,
purchase,  or attempt to induce any person to bid for or purchase  securities of
the same class for a period of five business days prior to the  commencement  of
such  distribution  and continuing  until the selling  securityholder  (or other
person  engaged  in  the  distribution)  is  no  longer  a  participant  in  the
distribution.

     If, at some time,  our company meets the NASDAQ  SmallCap  Market,  it will
apply for listing thereon.  If it should be accepted for listing  thereon,  then
certain  underwriters  may engage in passive market making  transactions  in our
Common Stock in accordance with Rule 103 of Regulation M.

     We may select  dealers  who are  members  of the  National  Association  of
Securities  Dealers,  Inc. to sell the shares,  and may pay commissions of up to
[10]% to such dealers.  No underwriter or dealer has made any firm commitment to
purchase or sell any of the Shares offered hereby.

Determination of Offering Price

     While  there is a limited  market for the stock,  the amount of stock to be
offered in this Offering is  substantially  greater than the daily volume in our
stock. We have, therefore, arbitrarily priced the stock

                                      -30-

<PAGE>

we are offering at a price that we feel is reflective of what the current market
would support, given the number of shares we are selling.  However, there can be
no  assurances  that after this  Offering the market price of the stock will not
decline.

                       OFFERING BY SELLING SECURITYHOLDERS

     An   additional   115,045   outstanding   shares  and  50,000  shares  (the
"Securityholder Shares") of Common Stock issuable upon exercise of warrants held
by the Selling Securityholders have been registered pursuant to the registration
statement under the Securities  Act, of which this Prospectus  forms a part, for
sale by such holders.  The  Securityholder  Shares may be sold subsequent to the
effective  date  of  the  Offering  if a  current  prospectus  relating  to  the
Securityholder  Shares is in effect and the Securityholder  Shares are qualified
for sale.  None of the shares being  registered  by the Selling  Securityholders
pursuant to this registration statement are being offered for sale in connection
with the  Offering.  The shares of Common  Stock and the shares  underlying  any
warrants  are not,  however,  subject  to a  lock-up.  We will not  receive  any
proceeds from the market sales of the  Securityholder  Shares,  although it will
receive  the  proceeds  from the  exercise of the  warrants  held by the Selling
Securityholders. The Company is paying all costs and expenses of registering the
Securityholder  Shares.  Sales of the Securityholder  Shares or the potential of
such sales  could have an adverse  effect on the market  price of our  company's
Common Stock. See "Risk Factors -- Shares Eligible for Future Sale."

     The Selling Securityholders and the number of Securityholder Shares held by
each are as listed below:

                                                                  SECURITYHOLDER

     There  are no  other  material  relationships  between  any of the  Selling
Securityholders  and our  company,  nor  have any  such  material  relationships
existed within the past three years.

     The sale of the Securityholder Shares by the Selling Securityholders may be
effected from time to time in transaction  (which may include block transactions
by or form the account of the Selling  Securityholders) in the  over-the-counter
market or in negotiated  transactions,  a combination of such methods of sale or
otherwise.  Sales may be made at fixed  prices  which may be changed,  at market
prices prevailing at the time of sale, or at negotiated prices.

     Selling  Securityholders  may effect  such  transactions  by selling  their
securities directly to purchaser,  through  broker-dealers  acting as agents for
the Selling  Securityholders  or to  broker-dealers  who may purchase  shares as
principals and thereafter sell the securities from time to time in the market in
negotiated transactions or otherwise.  Such broker-dealers,  if any, may receive
compensation in the form of discounts,  commissions, or concessions from Selling
Securityholders  and/or the purchasers from whom such  broker-dealers may act as
agents or to whom they may sell as principals or otherwise  (which  compensation
as to a particular broker-dealer may exceed customary commissions).

     At the time a particular  offer of  Securityholder  Shares is made by or on
behalf of a Selling Securityholder, to the extent required, a Prospectus will be
distributed  that will set  forth the  number  of  Securityholder  Shares  being
offered  and the  terms  of the  offering,  including  the  name or names of any
underwriters,  dealers,  or  agents,  if any,  the  purchase  price  paid by any
underwriter   for  any   Securityholder   Shares   purchased  from  the  Selling
Securityholder,  and any  discounts,  commissions,  or  concessions  allowed  or
reallowed or paid to dealers, and the proposed selling price to the public.

     If any of the following  events occurs,  this Prospectus will be amended to
include  additional  disclosure  before  offers and sales of the  Securityholder
Shares are made: (i) to the extent such  securities are sold at a fixed price or
by option at a price other than the prevailing market price, such price would be
set  forth  in  this  Prospectus;  (ii) if the  securities  are  sold  in  block
transactions  and the purchaser  wishes to resell,  such  arrangements  would be
described in this Prospectus;  (iii) if the compensation  paid to broker-dealers
is   other   than   usual   and    customary    discounts,    commissions,    or
concessions,disclosure of the terms of the transaction would be included in this
Prospectus.  This  Prospectus  would also disclose if there are other changes to
the stated plan of distribution, including arrangements that either individually
or  as  a  group  would   constitute  an   orchestrated   distribution   of  the
Securityholder Shares.

     Under applicable  rules and regulations  under the Exchange Act, any person
engaged in the  distribution  of  Securityholder  Shares may not  simultaneously
engage in market making activities with respect to any securities of the Company
for a period of at least two (and up to nine) business prior to the commencement
of such distribution.  In addition, each Selling Securityholder desiring to sell
Securityholder  Shares  will be  subject  to the  applicable  provisions  of the
Exchange  Act and the  rules  and  regulations  thereunder,  including,  without
limitation, Regulation M, which provisions may limit the timing of the purchases
and sales of shares of our company's securities by such Selling Securityholders.

     The  Selling   Securityholders  and  broker-dealers,   if  any,  acting  in
connection  with such  sales  might be deemed to be  "underwriters"  within  the
meaning of Section 2(11) of the Securities  Act, and any commission  received by
them and any profit on the resale of the securities  may be deemed  underwriting
discounts and commissions under the Securities Act.

                         SHARES ELIGIBLE FOR FUTURE SALE

     If we sell the  maximum  number of shares  in this  Offering,  we will have
4,575,660 common shares outstanding. Other than shares sold to affiliates of the
Company,  the shares  sold in this  Offering  will be freely  tradeable  without
restriction  under the  Securities  Act of 1933 (the  "Act").  Of the  3,575,660
shares of common stock  currently  outstanding,  2,368,266 are freely  tradeable
without  restriction  under the Act.  The  remaining  1,207,394  shares  held by
existing  shareholders are deemed "restricted"  securities within the meaning of
Rule 144 under the Act.

     In general, under Rule 144, restricted securities held by any person who is
not an affiliate of the company and who has beneficially owned his or her shares
for at least two years are  freely  tradeable.  In  addition,  under Rule 144, a
person who has beneficially  owned restricted  securities for at least one year,
including  persons who may be deemed  "affiliates"  of the company,  as the term
affiliate  is  defined  in Rule  144,  would be  entitled  to sell,  within  any
three-month  period,  a number of common  shares of which  does not  exceed  the
greater  of 1% of our then  outstanding  common  shares  or the  average  weekly
trading  volume in the  over-the-counter  market during the four calendar  weeks
preceding the date on which notice of the sale is filed with the  Securities and
Exchange  Commission.  No sales  are  permitted,  however,  unless  the  current
information  about the Company  prescribed  by Rule 144 is  publicly  available,
sales are made through brokers or market makers in the manner  prescribed by the
rule,  and all other  requirements  of the rule are met. The  restricted  shares
outstanding  have been held for  varying  periods of time,  and  certain of such
shares  have been  held for the  requisite  periods  and may be sold at any time
subject to the volume  limitations  set forth  above.  If there are  significant
sales of our common shares by the company's  existing  shareholders  or sales of
any of the shares  underlying  warrants  when such shares  have been  registered
pursuant to an effective registration statement,  the price of our common shares
may go down.

     There is presently no agreement by any holder,  including  "affiliates"  of
our company, of "restricted" shares not to sell his shares.

                            DESCRIPTION OF SECURITIES

     The authorized capital stock of the Company consists of 5,000,000 shares of
common  stock  having a par value of $.01 each (the  "Common  Stock"),  of which
3,575,660  shares  are  currently  outstanding  and  11,316  shares  are held in
treasury. There are currently approximately [249] holders of Common Stock.

Common Stock

     Each share of Common Stock is entitled to one vote on all matters submitted
to a vote of  shareholders.  The Common  Stock does not have  cumulative  voting
rights,  which means that the holders of a majority of the outstanding shares of
Common Stock may elect all of the  directors  of our  company.  The Common Stock
does not have any  preemptive  rights.  Stockholders  holding a majority  of the
voting power of the capital stock issued and  outstanding  and entitled to vote,
represented  in person or by proxy,  are necessary to constitute a quorum at any
meeting of our  stockholders,  and the vote by the holders of a majority of such
outstanding shares is required to effect certain  fundamental  corporate changes
such as liquidation, merger or amendment of our Certificate of Incorporation.

     Holders of Common Stock are entitled to receive dividends pro rata based on
the number of shares held,  when,  as and if declared by the Board of Directors,
from  funds  legally  available  therefor.  In the  event  of  the  liquidation,
dissolution or winding up of the affairs of our company, all assets and funds of
our company remaining after the payment of all debts and other liabilities shall
be  distributed,  pro rata,  among the holders of the Common  Stock.  Holders of
Common Stock are not entitled to preemptive, subscription, or conversion rights,
and there are no redemption or sinking fund provisions  applicable to the Common
Stock.  All  outstanding  shares of Common  Stock are,  and the shares of Common
Stock offered hereby will be when issued, fully paid and non-assessable.

Stock Options, Stock Option Plan, and Other Agreements to Issue Stock

     We have  outstanding  (i) options to  consultants  and third parties (a) to
purchase  50,000  shares  exercisable  for five  years at $1.85 per  share,  (b)
options to purchase 75,000 shares exercisable for five years at $1.12 per share,
(c) options to purchase 200,000 shares  exercisable for two years, as to 100,000
shares at $1.25 per share and as to 100,000  shares at $1.75 per share,  and (d)
50,000 shares  exercisable  for five (5) years from date of vesting at $1.25 per
share.

     The Company has granted options to purchase  300,000 shares  exercisable at
$.50 per share pursuant to an employment  agreement with our President,  100,000
options of which have vested and the remaining  200,000  options to vest 100,000
options on each of October 1, 1999, and October 1, 2000.

     We have also adopted a stock option plan for officers, directors, and other
key employees of the Company.  A total of 450,000  shares have been reserved for
issuance  under the plan,  and  options  for an  aggregate  of  190,000  shares,
exercisable at $.50 per share, have been granted to date.

     We issued 50,000  shares of Common Stock to MPX pursuant to our  consulting
agreement. Pursuant to the consulting agreement dated March 10, 1999, with Mint,
in addition to the options set forth above,  we issued  25,000  shares under the
agreement  and we are  obligated  to issue an  additional  37,500  shares to the
consultant on June 10, 1999,  and an additional  37,500 shares on July 10, 1999,
if the consulting agreement has not been previously terminated.

                         REPORT OF INDEPENDENT AUDITORS


                            Charles J. Birnberg, CPA
                               150 Overlook Avenue
                          Hackensack, New Jersey 07601








                                                                  March 16, 1999


To The Board of Directors of Tech Laboratories, Inc.



     I have audited the Balance Sheets of Tech Laboratories, Inc. as of December
31, 1997 and 1998 and the related  Statements  of Income and Retained  Earnings,
and Cash Flows for the years then  ended.  These  financial  statements  are the
responsibility of the Company's management.

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

     Therefore,  the  financial  statements  in my opinion,  present  fairly the
financial position of Tech  Laboratories,  Inc. as of December 31, 1998 and 1997
and the  results  of  operations  and cash  flows  for the years  then  ended in
conformity with generally accepted accounting principles.




                                                     Sincerely,

                                                     /s/ Charles J. Birnberg

                          NOTES TO FINANCIAL STATEMENTS
                 FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1998

(1) Summary of Significant Accounting Policies

     INVENTORIES - Inventories are valued at cost or market, whichever is lower.
The FIFO cost method is generally used to determine the cost of the inventories.
At December 31, 1997 and 1998 physical inventories were taken and tested.

PROPERTY AND  DEPRECIATION - Additions to property and equipment are recorded at
cost. Depreciation is computed using the straight-line method over the estimated
useful lives of the assets as follows:

                           ASSETS                ESTIMATED USEFUL LIVES

                           Machinery                 5 to 7 years
                           Furniture & Fixtures      5 to 7 years

Maintenance  and  repairs  are  charged  to  expense  as  incurred.  The cost of
betterments is capitalized and depreciated at appropriate rates. Upon retirement
or other  disposition of property items,  cost and accumulated  depreciation are
removed from the accounts and any gain or loss is reflected in the  statement of
income.

INCOME  TAXES - Income tax expense is based on reported  income and deferred tax
credit is provided for temporary differences between book and taxable income.

MARKETABLE  SECURITIES - The marketable  securities are recorded at the lower of
cost or market.  The cost of  securities  was $59,343 at  December  31, 1997 and
$56,693 at December 31, 1998.

(2) Inventories:

Inventories at December 31, 1997 and 1998 were as follows:

year ended December 31, 1998 of 2,202,905.

At December 31, 1997 and 1998,  the balance of operating loss  carryforward  was
$1,049,903 and $1,219,007,  respectively, which can be utilized to offset future

Indemnification of Directors and Officers

     The  Company is  incorporated  in New  Jersey.  Under  Section  ____ of the
Corporation  Law of the State of New Jersey,  a New Jersey  corporation  has the
power,  under  specified  circumstances,  to indemnify its directors,  officers,
employees,  and agents in connection with actions, suits, or proceedings brought
against them by a third party or in the right of the  corporation,  by reason of
the fact that they were or are such directors,  officers, employees, and agents,
against expenses incurred in any action, suit, or proceeding. The Certificate of
Incorporation  and the By-laws of the Company  provide  for  indemnification  of
directors  and  officers  to  the  fullest  extent   permitted  by  the  General
Corporation Law of the State of New Jersey.

     The  General  Corporation  Law of the State of New Jersey  provides  that a
certificate of  incorporation  may contain a provision  eliminating the personal
liability  of a director to the  corporation  or its  stockholders  for monetary
damages for breach of fiduciary duty as a director  provided that such provision
shall not  eliminate or limit the  liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders,  (ii) for
acts of omissions not in good faith or which involve intentional misconduct or a
knowing  violation of law,  (iii) under Section ____  (relating to liability for
unauthorized  acquisitions or redemptions of, or dividends on, capital stock) of
the  General  Corporation  Law of the  State  of New  Jersey,  or  (iv)  for any
transaction from which the director derived an improper  personal  benefit.  The
Company's Certificate of Incorporation contains such a provision.

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

Undertakings

         The undersigned registrant hereby undertakes:


                                      II-3

<PAGE>

     (a) 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 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

     (b) 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.

     (c) The undersigned registrant hereby undertakes that:

          (i) For purposes of determining any liability under the Securities Act
     of 1933, the information  omitted from the form of prospectus filed as part
     of this registration  statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant  pursuant to Rule 424(b)(1) or
     497(h)  under  the  Securities  Act  shall  be  deemed  to be  part of this
     registration statement as of the time it was declared effective.

          (ii) For the purpose of determining any liability under the Securities
     Act of  1933,  each  post-effective  amendment  that  contains  a  form  of
     prospectus 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

                              EMPLOYMENT AGREEMENT

     AGREEMENT  made as of the  1st day of  October,  1998 by and  between  Tech
Laboratories,  Inc.,  with its  principal  offices at 955  Belmont  Ave.,  North
Haledon,  NJ 07508 (the  "Company"),  and  Bernard M.  Ciongoli,  residing at 17
Liberty Ridge Trail, Totowa, NJ (the "Executive").

                              W I T N E S S E T H:

     WHEREAS, the Executive is currently employed by the Company in the capacity
of President and Chief Executive Officer ("CEO");

     WHEREAS,  the  Company  desires  to insure  the  continuing  benefit of the
services of the Executive, and,

     WHEREAS,  the  Executive is willing to continue to render such  services to
the Company on the terms and conditions herein set forth;

     NOW,  THEREFORE,  in  consideration  of the premises  and mutual  covenants
herein  contained,  and for other good and valuable  consideration,  receipt and
sufficiency of which is hereby  acknowledged by the parties hereto,  the parties
hereto  agree as  follows:

1.   Upon execution of this Agreement, all prior employment agreements,  whether
     written or oral,  between  the  Executive  and the  Company,  or any of its
     parents, subsidiaries, affiliates, or predecessor constituent corporations,
     are terminated and are of no further force and effect.

2.   Subject to the terms and  conditions  hereinafter  set forth,  the  Company
     hereby employs the Executive, and the Executive hereby agrees to and enters
     into the employ of the Company, or of affiliate any parent,  subsidiary, of
     affiliate of the Company as the company shall from time to time select, for
     an  employment  term  commencing  as of the 1st day of October,  1998,  and
     continuing  for a period  of three  years  from  such  date  (the  "Term of
     Employment").  At the end of the initial Term of Employment, this Agreement
     shall automatically be renewed for an

<PAGE>


     additional  three-year  period;  unless either party  provides at least 180
     days written notice of its decision not to renew their Term of Employment.

3.   During the Term of Employment,  the Executive shall render and perform such
     services  as  President  and CEO or such  other  executive  officer  of the
     Company  as may be  assigned  to him  from  time to time  by the  Board  of
     Directors.  If the Executive is elected as a Director of the Company by the
     Shareholders,  he shall receive no additional compensation for serving as a
     Director so long as he is  employed by the Company on a full-time  basis in
     an executive position.

4.   During the Term of  Employment,  the  Executive  shall  devote his business
     time,  attention,  skill,  and efforts to the performance of his duties for
     the  Company,  except for  reasonable  vacation  and except for  illness or
     incapacity, but nothing in this Agreement shall preclude the Executive from
     devoting  reasonable  periods for:

     (a)  Serving  as a  Director,  trustee,  or  member of a  committee  of any
          organization  involving  no  conflicting  interests  with those of the
          Company;

     (b)  Delivering  lectures,  fulfilling  speaking  engagements,  teaching at
          educational institutions or business organizations;

     (c)  Engaging in charitable and community activities; and

     (d)  Managing his personal  investments;

     Provided that such activities do not,  individually or together,  interfere
     with the regular performance of his duties and responsibilities  under this
     Agreement. The Company shall pay all reasonable costs and expenses incurred
     by the Executive in any undertaking under Subsections  (a)-(c),  inclusive,
     above when  participation  in said  activities  provides direct or indirect
     benefit to the Company.

5.   For all services to be rendered by the Executive in any capacity during the
     Term  of  Employment,   including,  without  limitation,   services  as  an
     executive, officer, director or member of a

<PAGE>


     committee of the Company or its  subsidiaries,  divisions,  and affiliates,
     the  Executive  shall  be paid as  compensation  such  salary,  payable  in
     accordance with the customary  payroll  practices of the Company (but in no
     event less frequently than  semi-monthly)  as the Board of Directors of the
     Company  may  determine  and any  bonus as the  Board of  Directors  of the
     Company may determine.

     During the Term of Employment as set forth in this Agreement,  it is agreed
     that the compensation  paid to the Executive shall be a base salary no less
     than Seventy Five  Thousand  ($75,000)  Dollars per annum until the Company
     completes a financing  of at least One  Million  Dollars in gross  proceeds
     (debt or equity),  at which time the base salary  shall  become One Hundred
     Twenty-Five  Thousand  ($125,000) Dollars per annum. It is acknowledged and
     agreed  that the  Company  has sold  approximately  $750,000  in an ongoing
     finance,  so that  approximately  $250,000  needs to be raised to reach the
     $1,000,000 referred to in the previous sentence.

6.   In addition, the Executive will receive a cash bonus of two percent (2%) of
     the  Company's  sales in excess of $1,000,000 in each fiscal year that ends
     during  the Term of  Employment,  beginning  with the  fiscal  year  ending
     December  31,  1998,  which bonus will be paid on or before  February 15 of
     each  year.  The  Company  will  grant to the  Executive  stock  options to
     purchase up to 100,000  shares of the Company's  common stock at a price of
     $.50 per share on October 1 of each year of this Agreement,  beginning with
     October  1  1998;  and  the  Executive  shall  participate  in any  Company
     incentive  plan  which  may be  established  and  modified  by the Board of
     Directors or  shareholders  from time to time. The Executive  shall also be
     entitled to reimbursement by the Company for reasonable  expenses  actually
     incurred  by him on its  behalf  in the  course  of his  employment  by the
     Company,  upon the presentation by the Executive,  from time to time, of an
     itemized  account of such  expenditures,  together  with said  vouchers and
     other receipts as the Company may require.

<PAGE>


7.   The  Executive  shall be  entitled  to  vacations  in  accordance  with the
     Company's prevailing policy for its operating executives.

8.   The  rights  of the  Executive  or any  other  person  to  the  payment  of
     compensation  or other benefits under this Agreement shall not be assigned,
     transferred anticipated, conveyed, pledged, or encumbered except by will or
     the laws of descent and distribution;  nor shall any such right or interest
     be in any manner subject to levy, attachment,  execution,  garnishment,  or
     any other seizure under legal,  equitable,  or other process for payment of
     debts,  judgements,   alimony,  or  separate  maintenance,  or  reached  or
     transferred by operation of law in the event of bankruptcy,  insolvency, or
     otherwise.

9.   In the event of the Executive's  involuntary  termination of employment due
     to circumstances  beyond the control of the Company, or in the event of the
     Executive's  involuntary  termination  for any reason,  other than for just
     cause due to theft or fraud,  the Executive  shall be entitled to severance
     compensation or benefits as provided in this paragraph 9. Nothing contained
     herein,  however, shall be construed so as to include absence or failure to
     perform due to illness as a basis for termination.

     (a)  Subject to the provisions of paragraph 9(b) below, the Executive shall
          be entitled  (upon such  involuntary  termination  of  employment)  to
          immediate  severance  compensation  equal  to an  amount  equal to the
          Executive's  base  salary  for the  remaining  period  of the  Term of
          Employment.

     (b)  The Executive shall be entitled (upon such involuntary  termination of
          employment),  in addition to the severance  compensation  described in
          paragraph  9(a) above,  to the benefits  described  in paragraph  9(c)
          below, as follows:

     (c)  The  Executive  will be eligible to  continue  to  participate  in the
          following employee benefit plans (to the extent  permissible  therein)
          for a period of one year from the date of such

<PAGE>


          involuntary termination of employment.  Cost of such participation for
          the  Executive and eligible  dependents  shall be born by the Company,
          provided the Executive continues to make all contributions required as
          of the date of termination to maintain his eligibility;

          Medical Insurance Plan.........................COBRA (Company paid)*

          Dental Plan....................................COBRA (Company paid)*

          *    The Executive  will have the option to continue this coverage for
               an  additional  six months  (beyond the twelve months paid by the
               Company) by paying the full monthly premium.

10.  Nothing  contained  herein  shall in any way affect or  interfere  with the
     Executive's rights or privileges under any qualified deferred compensation,
     retirement, pension, profit sharing, bonus, insurance,  hospitalization, or
     other  employee  benefit  plan,  program or  arrangement,  now in effect or
     hereafter  adopted,  in  which  the  Executive  is  entitled  to  share  or
     participate as an employee of the Company.

11.  During the Term of  Employment,  if Executive  shall,  for a period of more
     than three (3)  consecutive  months or for  periods  aggregating  more than
     twelve (12) weeks in any fifty-two  consecutive weeks, be unable to perform
     the services provided for herein, as a result of illness or incapacity or a
     physical,  mental, or other disability of any nature, the Company may, upon
     not less than thirty (30) days notice, terminate the Executive's employment
     hereunder. The Executive shall be considered unable to perform the services
     provided for herein if he is unable to attend to the normal duties required
     of him. In such event,  the Company shall pay to the  Executive,  or to his
     legal  representatives,  base  compensation  as  specified  in paragraph 5,
     hereof,  for a period of twelve (12)  months from the date of  termination.
     Upon completion of the termination payments provided for in this paragraph,
     all of the Company's  obligations to pay compensation  under this Agreement
     shall cease.

<PAGE>


12.  The  Company  makes  no  representations,   guaranty,  warranty,  or  other
     assurance of any kind to the  Executive or any other person  regarding  the
     federal,  state or local tax consequences of this Agreement or any payments
     hereunder, and the company does not agree to indemnify the Executive or any
     other  person  for any  federal,  state,  or local  taxes of any kind  with
     respect to payments hereunder.

13.  This  Agreement  shall be  binding  upon and  inure to the  benefit  of the
     Company,  its  successors  and assigns,  and the  Executive  and his heirs,
     executors, administrators, and legal representatives.

14.  The Company will not consolidate or merge into or with another  corporation
     or entity,  or transfer all or  substantially  all of its  business  and/or
     assets to another entity, directly or indirectly,  unless such other entity
     (hereinafter  referred to as the  "Successor")  shall assume this Agreement
     and the obligations of the Company hereunder, and upon such assumption, the
     Executive and the Successor shall become obligated to perform the terms and
     conditions hereof. However, if during the first 180 days following any such
     consolidation or merger,  the Executive  determines that he does not desire
     to remain  employed by the Successor or the Successor  determines  that the
     services of the Executive are no longer  required,  such  consolidation  or
     merger  shall be  deemed  an  involuntary  termination  of the  Executive's
     employment,  and the Executive  shall be paid an amount equal to his annual
     base salary at the time of the  consolidation or merger.  This payment will
     be  made  to  the  Executive  in a  single  lump  sum at  the  time  of the
     termination.

15.  The Executive will not, at any time during the Term of Employment, or for a
     period  of one year  after the  voluntary  termination  of the  Executive's
     employment,  directly or  indirectly  disclose or furnish any other person,
     firm, or corporation any information relating to the Company or its parent,
     subsidiaries,  or  affiliates  with respect to  technology of the Company's
     products, methods of obtaining business, advertising products, customers or
     supplies, or any confidential or

<PAGE>


     proprietary  information acquired by the Executive during the course of his
     employment by the Company or its parent, subsidiaries, or affiliates.

16.  This Agreement  constitutes the entire agreement between the parties hereto
     relating to the subject  matter set forth herein and  supersedes  any prior
     oral  and/or   written   agreements,   understandings,   negotiations,   or
     discussions  of the parties.  There are no warranties,  representations  or
     agreements  between  the  parties in  connection  with the  subject  matter
     hereof,  except  as  set  forth  or  referred  to  herein.  No  supplement,
     modification,  waiver,  or  termination  of this Agreement or any provision
     hereof  shall be binding  unless  executed  in writing by the parties to be
     bound thereby.  Waiver of any of the provisions of this Agreement shall not
     constitute a waiver of any other  provision  (whether or not similar),  nor
     shall  such  waiver   constitute  a  continuing   waiver  unless  otherwise
     specifically provided.

17.  The failure of either party at any time require performance by the other of
     any provision  hereof shall not affect in any way the full right to require
     such  performance  at any time  thereafter,  nor shall the waiver by either
     party of the  breach  of any  provision  hereof be taken or be held to be a
     waiver of the provision itself.

18.  Any notice or other  communication  required or permitted to be given under
     or in  connection  with this  Agreement  shall be in writing,  delivered in
     person or by public telegram,  or by mailing same,  certified or registered
     mail, postage prepaid, in an envelope addressed to the party to whom notice
     is given,  at the address  given at the beginning of this  Agreements,  and
     shall be effective  upon receipt  thereof.  Each party shall be entitled to
     specify a  different  address by giving  notice as  aforesaid  to the other
     party.

19.  The invalidity or  unenforceability  of any  paragraph,  term, or provision
     hereof  shall  in no way  affect  the  validity  or  enforceability  of the
     remaining paragraphs, terms, or provisions hereof. In addition, in any such
     event,  the parties agree that it is their intention and agreement that any
     such

<PAGE>


     paragraph,   term  or  provision   which  is  held  or   determined  to  be
     unenforceable  as written shall  nonetheless be in force and binding to the
     fullest extent permitted by law as though such paragraph, term or provision
     had  been  written  in  such  a  manner  and to  such  an  extent  as to be
     enforceable  under the circumstance.  Without limiting the foregoing,  with
     respect to any restrictive  covenant  contained herein, if it is determined
     that any such  provision  is  excessive  as to  duration  or  scope,  it is
     intended that it nevertheless shall be enforced for such short duration, or
     with such narrower scope, as will render it enforceable.

20.  All of the terms and  provisions of this  Agreements  shall be binding upon
     and shall inure to the benefit of the parties  hereto and their  respective
     heirs, executors, administrators, transferees, successors, and assigns.

21.  This Agreement  shall be governed and construed under the laws of the State
     of New Jersey.

     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be
entered into as of the date and year herein above first set forth.

F. Net Profits.  All pre-tax profits shall be calculated  according to generally
accepted  accounting  principles fairly and consistently  applied;  and shall be
distributed  quarterly  in  arrears,  70% to the First  Party and 30% the Second
Party.  On April 1, 2001 and annually  thereafter for the balance of the Term of
this Amended Joint Marketing  Agreement or any renewal term as provided  herein,
the Party shall  reanalyze the profit  sharing  allocation.  Such  reanalyzation
shall involve an analysis of the actual  pre-tax profit of the First Party as to
the sale of the  Products.  If the actual  pre-tax  profit of the First Party is
more than 16% then the  profit  share of the First  Party and the  Second  Party
shall be reallocated to increase the percentage of the Second Party and decrease
the  percentage of the First Party to properly  reallocate  the profit earned by
party of the First  Party in excess of 16%.  If the profit of the First Party is
less than 16%, then the First Party shall have the unilateral right to terminate
this Amended Joint Marketing Agreement.

F. Royalties. In addition to any other sums earned under this Amended Agreement,
the Party of the Second  Party  shall earn a Royalty  equal to 5% of the cost of
any Products  manufactured by Tech  Laboratories,  Inc. and marketed pursuant to
