                               PROSPECTUS SUMMARY


     Unless the  context  indicates  otherwise,  all  references  herein to "we"
include  Tech  Labs  and its  wholly-owned  subsidiary,  Tech  Logistics,  Inc.,
collectively,  and references to "Tech Labs" 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."

                                    Tech Labs

     We manufacture and sell various  electrical and electronic  components.  We
recently   acquired  from   NORDX/CDT,   INC.,  a  subsidiary  of  Cable  Design
Technologies  Corp.,  the  DynaTraX(TM)  digital  matrix  technology  which is a
patented,  state-of-the-art,  transparent  customer-premise,  high-speed network
switching  system.  We believe  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.

     The  DynaTraX(TM)  technology  will  also  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 users.

     We also market and manufacture,  under our exclusive  license,  an infrared
perimeter  intrusion and anti-terrorist  detection system or "IDS". We currently
market this product to government agencies and private industry.


     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  limited  sales  revenue,  have a  history  of  losses  and  may not be
profitable in the future.

     Our limited sales revenue and history of losses makes it uncertain  when or
if we will become profitable. 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,  we must increase our sales and
margins of our products significantly in order to avoid continued losses.


Our capital  requirements  may be greater than the proceeds we receive from this
offering.

     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.  Our primary capital
requirements over the next 12 months include:

o    payments of trade payables;

o    marketing expenses;

o    research and development; and

o    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.  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.

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 need the  proceeds of this  offering to
market these products and develop and market new products.



                                       -4-

The market for our service is uncertain.

     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.  Our success  depends upon
several factors including, among others:

o    The development of an effective marketing and distribution network;

o    The acceptance of our products by potential users; and

o    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.  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 new  products,  and
additional costs and expenses that may exceed current estimates.

The market in which we sell our  products  is  characterized  by many  competing
technologies  and  continual  advancements.  We  may  not  be  able  to  compete
effectively against other technologies.

     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:

o    technologically equivalent or superior to competing products;

o    cost-effective; and

o    flexible and 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(TM)-based  products,  the sales
and  operations  history of such products has been limited.  Because we have not
sold a sufficient  number of DynaTraX(TM)  products since our acquisition of the
technology,  we can not judge the level of performance of this product.  We also
can  not  determine  at this  time  whether  our  DynaTraX(TM)  product  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.


                                       -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.


Our dependence on third parties could hamper our growth prospects.

     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 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.  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. 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.

We may be unable to protect certain 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,  which have been issued to date only in England, we intend
to rely substantially on unpatented,  proprietary  information and know-how.  We
are also  presently  prosecuting  the  patent  applications  filed in the United
States and Europe.


                                       -6-

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 if such coverage can be
obtained on affordable terms.


     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  has  acquired  a  significant  interest  in Tech Labs 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 Tech Labs is likely to remain in the
hands of management.

The offering price of the shares was arbitrarily  determined and may not reflect
ordinary investment criterion.


     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.




We manufacture and sell the IDS system under a license agreement

     We entered into an Amended 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  agreements  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, it
will be  necessary  at that time to  negotiate  a new  agreement  or  license or
acquire a suitable replacement technology.

Potential unavailablility of components; limited or single source of supply.

     Current  inventory  component  purchases for all our products are made from
OEMs, brokers and other vendors.  We typically have more than a single source of
supply for each part,  component or service . 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.

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.  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. 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,  Mr. Carmine O.
Pellosie,  Jr. and Mr.  Richard  Rice.  Mr.  Ciongoli and Mr.  Bjorndal are both
employed by Tech Labs.  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.


We may need  additional  capital  in the  future  and may not be able to  secure
adequate funds in terms acceptable to us.

     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 we may be unable to secure
such financing.  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.

Since this is a direct participation offering and there is no underwriter, there
may be less due diligence performed.

     This offering is a direct participation  offering.  No underwriter has been
retained  by Tech Labs to sell  these  securities.  One of the  functions  of an
underwriter,  along with such underwriter's  counsel,  is the performance of due
diligence in addition to that performed by our counsel.  Without an underwriter,
we do not have the benefit of an additional due diligence review.

                                 USE OF PROCEEDS


     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:


                                             MINIMUM                    MAXIMUM

     The  foregoing  represents  our best  estimate  of the net  proceeds of the
offering based on current planning and business conditions. Tech Labs management
has broad  discretionary  authority to  determine  the exact  allocation  of the
proceeds for the  purposes  set forth above and the timing of the  expenditures,
which may vary  significantly  depending  upon the exact amount of funds raised,
the time and cost  involved in deploying  the funds and other  factors.  Pending
usage of the funds, as set forth above, the funds will be invested in short-term
interest bearing securities or money market funds.

     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, defined as 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 June 30, 1999  (unaudited),  was  $1,138,407 or
$.32 per common share.

     Giving  effect  to the  issuance  after  June 30,  1999 of  571,428  shares
assuming an offering  price of $3.50 per share  (minimum) and  1,000,000  shares
assuming an offering  price of $3.50 per share  (maximum) and the receipt of the
net  proceeds  by Tech Labs,  the pro forma net  tangible  book value would have
been:

o    $3,038,407 or $.73 per share upon completion of the minimum offering; and

o    $4,538,407 or $.99 per share upon completion of the maximum offering.

     This  represents  an immediate  increase in net tangible book value of $.41
per  common  share  (minimum  offering)  and $.67 per common  share (at  maximum
offering) to the existing  shareholders  and an immediate  dilution of $2.77 per
common share (minimum offering) and $2.51 per common share (maximum offering) to
persons purchasing shares in this offering. The following table illustrates this
per share dilution:


                                                              Minimum    Maximum

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

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 six months
ended June 30, 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
June 30, 1998 and 1999:

</TABLE>



     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


Six Months  Ended June 30,  1999,  Compared to Six Months Ended June 30, 1998 --
Unaudited.

     Sales  were  $160,304  for the first  six  months  of 1999 as  compared  to
$172,319 for the six months ended June 30, 1998. The decrease was due to limited
marketing efforts and the lack of new product introductions.

     Cost of sales of $112,213 for the six months  ended June 30, 1999  compared
to  $173,182  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 increased by $109,742 or 58%
in the first half of 1999 as compared to the prior period in 1998 which resulted
from higher than normal  expenses in 1999 due to  professional  fees  associated
with the acquisition of DynaTraX(TM).

     Losses from operations of ($250,220) in the first half of 1999 increased by
$57,373 or 30% compared to losses of ($189,432) for the prior period as a direct
result of higher 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 lower costs IDS 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 six months
ended June 30, 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.


Year 2000 Readiness

     Many currently  installed  computer systems and software products are coded
to accept only two digit  entries in the date code field and cannot  distinguish
21st century dates from 20th century dates.  These date code fields will need to
distinguish  21st century dates from 20th century dates to avoid system failures
or miscalculations  causing  disruptions of operations,  including,  among other
things, a temporary inability to process  transactions,  send invoices or engage
in similar normal business activities. As a result, many companies' software and
computer  systems  may need to be  upgraded  or replaced in order to comply with
such "Year 2000" requirements.

     Our  Year  2000  review  is in  progress.  We  believe  that all of our own
computer systems and products will be compliant before 2000.

     o    Products.  The DynaTraX(TM)  system software runs on Microsoft Windows
          NT, which is Year 2000 compliant.  The  DynaTraX(TM)  hardware is also
          compliant.   The  IDS  and  the  various   electronic  and  electrical
          components that we manufacture neither contain microprocessors nor are
          they reliant on time or date software. We believe such equipment to be
          unaffected by the Year 2000 problem.

     o    Vendors.  All of our  components  are  bought  "off the shelf" and are
          manufactured  by  numerous  companies.  We  believe we will be able to
          replace   supplies   from  any   vendor   experiencing   manufacturing
          difficulties due to the Year 2000 problem.

     o    IT  Systems.  We  conducted  a survey  of our  information  technology
          hardware and and have scheduled  upgrades  and/or  replacements of all
          identified  Year 2000  non-compliant  hardware and  software  prior to
          2000.

     o    Costs. We do not currently expect that costs associated with Year 2000
          compliance  will   materially   affect  our  operations  or  financial
          position. However, if we discover Year 2000 problems in the future, we
          may  not be  able  to  develop,  implement,  or  test  remediation  or
          contingency plans in a timely or cost-effective manner.

     o    Risks.  Failure  of  third  party  products,  such as a  breakdown  in
          telephone,  electric service or other utilities,  e-mail, voicemail or
          the  World  Wide  Web  could  cause  a  disruption   in  our  business
          operations.  Disruptions  in  services  provided  by banks,  telephone
          companies  and the U.S.  Postal  Service could  negatively  impact our
          business.  Although  we  believe  that  our  products  are  Year  2000
          compliant,  it is  possible  that they may not  contain the date codes
          necessary to operate in the year 2000.  Any failure of the products to
          perform could result in the delay or  cancellation  of product  orders
          and the  diversification  of managerial  and technical  resources from
          product  development  and other business  activities to attend to Year
          2000 issues.

                                    BUSINESS

General


     Tech Laboratories,  Inc., which was incorporated in 1947,  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.  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.

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) Asset Acquisition

     On April 27, 1999, we completed the acquisition of the DynaTraX(TM) system,
from  NORDX/CDT,  INC. for a purchase price of $500,000.  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,  including internet, high-speed data, digital voice and video; and,
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.

     We may be unable 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)  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 initially intend to market the DynaTraX(TM) 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 DynaTraX(TM).



                                      -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 from several  different
sources.  One  source  of  competition  is the  designated  employees  of  large
organizations  which  have been  hired to manage  and  maintain  their  internal
networks.   However,   we  believe  the  need  to  reduce   costs   through  the
implementation  of automated cost saving  technologies  such as the DynaTraX(TM)
technology, will provide Tech Labs with market opportunities.

     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,  which is a technology utilized by a number
of  companies,  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 which our  DynaTraX(TM)  technology  is designed to complete.
These tasks are:

     o    rearranging  network physical layer  connections e.g.s moves, adds and
          changes of equipment  such as computer  terminals;  fax machines;  and
          printers;

     o    testing circuits;

     o    managing and mainatining end-to-end network configuration; and

     o    maintaining 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 and currently  account for substantially all of the existing
market.


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.  Pellosie,  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. Pellosie'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 recently  begun  marketing  IDS 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.


     We are  marketing  our  IDS  product  to 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 our  products.  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 approval for the IDS from the U.S. Air Force 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.  Subsequent  to this  approval,  Tech Labs has received a
blanket order to provide 50 IDS systems to the U.S. Air Force.  Tech Labs has as
of the date of this Prospectus  shipped 6 systems under its blanket order to the
TASS prime contractor.  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:


     o    Industry announcements and presentations through business and industry
          trade groups;

     o    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

     o    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 the  communication/computer  centers  in the
eastern part of the United  States.  We plan to divide this area into four sales
regions:

     o    New England states;

     o    New York metropolitan area;

     o    Mid-Atlantic/Washington DC area; and

     o    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.


     We also 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  regional
sales/service centers:

o    Massachusetts;

o    Washington, DC; and

o    Florida

     We will repeat the process in the other areas as they become established.

     We  plan  to use our  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 fourth 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  approval from the U.S. Air Force for inclusion of
the IDS products in its TASS  program.  We received our first  blanket order for
our IDS product in May 1999.


     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 approved by
the Air Force 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.

Source of Supply

     Current  inventory  component  purchases for all our products 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 may
utilize 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.


Order Backlog

     The backlog of written firm orders for our products and services as of June
30, 1999, was as follows:

          As of June 30, 1999: $485,440

          As of June 30, 1998: $159,109


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.

Employees


     As of June 30, 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 corporate  headquarters and 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  have a five  (5)  year  employment  contract  with  Mr.  Ciongoli  that
commenced  October 1, 1998, and amended June 18, 1999. Mr. Ciongoli is currently
compensated at the base salary rate of $125,000 per annum.  Mr. Ciongoli is also
entitled to receive two (2%) percent of our sales in excess of $1,000,000 during
any year he is employed by ua. In  addition,  Mr.  Ciongoli  was also granted an
option  exercisable  for five (5) years from date of grant to  purchase  300,000
shares of stock at $.50 per share,  such option to vest in increments of 100,000
shares per annum on each anniversary date of the agreement commencing October 1,
1998.  The  agreement is  automatically  renewed for one (1) year unless  either
party  terminates  the  agreement  in  writing  at least  180 days  prior to the
expiration of the term or of any renewal period.



     In 1996 we granted to Mr. Ciongoli an option to purchase  100,000 shares of
common  stock  exercisable  for five (5) years at $.50 per share under our stock
option plan.

     We do not have  employment  agreements  with  any  other  officer  or other
employee. Our directors are not presently compensated.


Consultants


     We have  entered into a consulting  agreement  with MPX Network  Solutions,
Inc.  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. 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,  we 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 Tech Lab's products 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,  to provide  certain  financial and
business  consulting  services,   which  include  assisting  our  management  in
developing its business plan,  introducing Tech Labs to members of the financial
community,  and assisting us in our financial  planning.  Under the terms of the
consulting  agreement,  which may be  terminated by us upon ten (10) days' prior
written  notice,  we (a) issued 100,000  shares to Mint,  25,000 shares of which
were issued in June 1999 and 75,000 shares were issued in October 1999; and, (b)
granted 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 Tech Labs 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. Options issued pursuant to the
stock option plan are meant to qualify as  incentive  stock  options  within the
meaning of Secion 422A of the Internal  Revenue Code. 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
Tech Labs and certain affiliated parties.  Future transactions,  if any, must be
approved by the Board of Directors.

     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
for unpaid  salary  earned in the amount of $14,000 at $0.05 per share,  and Mr.
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.  Pellosie,  Jr.  to market  security  devices  distributed  by
International  Logistics,  Inc., a private-owned  company, of which Mr. Pellosie
was the president and principal  shareholder.  Mr. Pellosie became a director of
Tech Labs at that time. In May 1998, we acquired Mr. Pellosie's interest in Tech
Logistics,  Inc. for 15,000 shares of our common  stock.  See "Business -- Other
Recent Developments."

                              PLAN OF DISTRIBUTION


     We will receive proceeds from the sale of 1,000,000  shares,  aggregating a
maximum of $3,500,000,  before deducting offering  expenses,  if all such shares
are sold. We will not receive the proceeds of any sale of the  securities by any
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 any sales 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 Hudson  United Bank.  If a minimum of 571,428
shares offered for sale in our direct participation offering 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 our sole discretion
and all funds received from the sale of the shares will be returned to


                                      -28-

<PAGE>


the  purchasers  thereof with interest if the funds are held in escrow more than
90 days,  at the same rate as paid by the escrow bank,  and without  interest if
held less than 90 days. At the time that 571,428  shares have been sold prior to
the  expiration  of 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 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 of 1933, and any discounts, commissions, or concessions
received  by any such  underwriters,  dealers,  or  agents  may be  deemed to be
underwriting  discounts  and  commissions.  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, we meet the  requirements  of the NASDAQ  SmallCap Market
for listing of our shares,  we will apply for listing.  If our shares  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.


     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,
Pennsylvania, Michigan, Texas and Florida. 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  shares 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 of 1933 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 Tech Labs 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.




     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 90,045  outstanding  shares and 50,000 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 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 we will receive the proceeds from the exercise
of the  warrants  held by the selling  securityholders.  Tech Labs 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  common  stock.  See "Risk  Factors -- Shares
Eligible for Future Sale."

     The  selling  securityholders  and the number of shares held by each are as
listed below:


                                                                  SECURITYHOLDER

     There  are no  other  material  relationships  between  any of the  selling
securityholders and Tech Labs, nor have any such material  relationships existed
within the past three years.



     The sale of the securityholder  shares may be effected from time to time in
transaction,  which may  include  block  transactions,  in:

     o    the over-the-counter market;

     o    in negotiated transactions; or

     o    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 purchasers

     o    through broker-dealers acting as agents; or

     o    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.

     Broker-dealers,  if any, may receive compensation in the form of discounts,
commissions,  or concessions 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:

     o    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;

     o    If the  securities  are sold in block  transactions  and the purchaser
          wishes  to  resell,  such  arrangements  would  be  described  in this
          Prospectus;

     o    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 Tech Labs
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(1) common shares outstanding.  Other than shares sold to affiliates of
Tech Labs,  the shares sold in this  offering will be freely  tradeable  without
restriction  under the Securities Act of 1933. 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 under Rule 144.

     No sales are permitted,  however, unless the current information about Tech
Labs  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 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 our "affiliates",
of "restricted" shares not to sell his shares.

     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.


     There is a very limited market for our common stock and a more  substantial
market may not develop in the future;  or if 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;

     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.  Such high trading  prices may not 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.

                            DESCRIPTION OF SECURITIES


     Our authorized  capital stock consists of 5,000,000  shares of common stock
having a par value of $.01 each,  of which  3,575,660(1)  shares  are  currently
outstanding  and  11,316  shares  are  held in  treasury.  There  are  currently
approximately [___] 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 may
elect all of the  directors  of Tech Labs.  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  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.

     Tech Labs 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.  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 and are
obligated  to issue an  additional  37,500  shares as of July 10,  1999,  and an
additional 37,500 shares as of August 10, 1999.

                            Charles J. Birnberg, CPA
                               150 Overlook Avenue

                                                                  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


     CASH - Includes Tech Lab's  checking  account at Hudson United Bank.  There
are no Cash Equivalents.

     ACCOUNTS RECEIVABLE - Tech Labs recognizes sales when orders are shipped to
customers.  The allowance for bad debts is accrued based on a review of customer
accounts receivables aging.


     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:

     Work in Process & Finished Goods          38,007           67,759
                                             --------         --------
                                             $269,209         $270,118
                                             --------         --------

(3) Income/(loss) Per Share:

Income/(loss)  per share was calculated on the weighted average number of shares
outstanding  during the year ended December 31, 1997 of 1,550,048 and during the
year ended December 31, 1998 of 2,202,905.

(4) Income Taxes:

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
taxable income.

(5) Short-Term Loans Payable:

Loans payable to banks were as follows for the years indicated:

                                                     CURRENT         NON-CURRENT
YEAR ENDED      PAYEE              INTEREST RATE     AMOUNT            AMOUNT
- ----------      -----              -------------     ------            ------

 1997          Hudson United Bank    Prime +1.5%     $34,445            --
 1998          Hudson United Bank    Prime +1.5%     $32,742            --

Certain marketable securities are pledged as collateral on the above loan.


(6) Short-Term Loans Payable to Officers and Directors:

Demand loans payable  include loans from  stockholders,  officers and members of
the Board of  Directors.  The  outstanding  loan balances due as of December 31,
1997 and 1998 was $43,373 for each of such years.  The annual  interest rate for
these loans ranged between six (6%) percent and ten (10%)  percent.  One loan in
the  principal  amount of $11,500  together  with accrued  interest of $3,604 at
December 31, 1998 is secured by the assets of Tech Labs.


(7) Common Stock


In 1997, Tech Labs converted $217,500 of short term loans into 198,750 shares of
common stock.

In 1997 and 1998, Tech Labs completed a placement pursuant to Rule 504 of common
stock which raised $917,324.

(8) Commitments and Contingencies

     Tech Labs entered into an exclusive  agreement with Elektronik  Apparatebau
(EAG)  whereby  it  received  exclusive  rights to  manufacture  and  market IDS
products until September 30, 2007. Since Elektronik Apparatebau (EAG) receives a
share of the  incremental  gross  profit  generated by  incremental  IDS product
sales,  Tech  Labs has no future  commitments  or  contingencies  caused by this
agreement.

(9) Subsequent Events

     On April 27, 1999, Tech Labs completed the purchase of existing inventories
and test equipment of the DynaTrax(TM) Product Line from NORDX/CDT for $500,000.
In accordance  with the purchase price method of accounting,  the purchase price
for the assets  referenced  above was  allocated  to the assets  acquired on the
basis of preliminary  fair market values,  which may be revised at a later date.
Results  subsequent  to the date of  acquisition  will be included in Tech Lab's
financial  statements.  Had the  results of the  DynaTrax(TM)  acquisition  been
included  in our  consolidated  results  for 1998,  the  effect  would have been
material.

Indemnification of Directors and Officers


     Tech  Labs  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 Tech Labs  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 (a) for any breach of
the director's duty of loyalty to the corporation or its  stockholders,  (b) for
acts of omissions not in good faith or which involve intentional misconduct or a
knowing  violation of law, (c) 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 (d)  for  any
transaction from which the director derived an improper personal  benefit.  Tech
Labs'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.

     The  following  table  sets  forth the  expenses  in  connection  with this
Registration  Statement.  All of such  expenses  are  estimates,  other than the

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:


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

          (2) 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;

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

          (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:


          (1) 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.

          (2) 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

                    disposition  or assignment for the benefit of its respective
                    creditors;

               v)   The Consultant attempts to assign this Agreement without the

          (b) In  addition to the  Consulting  Fee,  for each of the  Consulting
     Period and the  Extension  Period,  the Company  shall pay to  Consultant a

     the first  $1,000,000 of the net sale price of all Products sold during the
     applicable period,  (ii) two (2%) percent of the next $1,000,000 of the net

          (c) "The net sale price of all  Products  sold  during the  applicable
     period," as used herein, means the price at which  Communication/Networking

     taxes,  freight  or  transportation  or other such  charges or costs,  less

     Products on the internal records of the Company, in its sole discretion.

          (d) The Company shall, as soon as practicable  after the close of each

<PAGE>


shall  notify  the  Company  in  writing  of its  objections,  if  any,  to such
statement.  In the event that  Consultant  does not object to the  statement  in
accordance  with this Section 4(d),  such  statement  shall deemed  accepted and
shall become final and binding upon the parties.  If Consultant  shall object to
the  statement,  and the parties  cannot  agree as to the subject  matter of the
statement,  the matter shall be submitted to the Company's independent auditors,
whose  determination,  to be  rendered  in not more than 30 days of  submission,
shall be final and binding  upon the  parties.  Payment of any  commissions  due
shall be made not  later  than 10 days  after  acceptance  of the  statement  or
resolution or determination of any objection, as the case may be.

          (e) If Consultant's engagement is terminated pursuant to Sections 3(a)
     or (b),  or if  Consultant  terminates  its  engagement  voluntarily,  then

     Consultant  a three (3) year  option to  purchase  50,000  shares of Common
     Stock  at an  exercise  price of  $1.25  per  share.  The  option  shall be
     exercisable  (i) as to 25,000  shares,  commencing 30 days after the end of
     the Consulting  Period, in full, if the net sale price of all Products sold
     during the  Consulting  Period equals at least  $3,000,000,  and (ii) as to
     25,000 shares, commencing 30 days after the end of the Extension Period, in

     among other  things,  that (i) if the net sale price of all  Products  sold
     shall be less than  $3,000,000  during either the Consulting  Period or the
     Extension Period, then the number of shares as to which the option shall be
     exercisable  as relates to such period shall be decreased in  proportion to
     the amount by which such net sale price is less than  $3,000,000,  and (ii)
     if Consultant's engagement is terminated (A) pursuant to Section 3(a) or if
     Consultant terminates its engagement voluntarily, then the number of shares
     as to which the option shall be  exercisable  shall be determined as of the
     date of such termination,  or (B) pursuant to Section 3(b), then the option
     shall  terminate  as to any and all  shares,  and  Consultant  shall not be
     entitled to exercise the option as to any shares.

     5.   Expenses.

     The  Consultant  shall be  solely  responsible  for  paying  any  expenses,
including,   without  limitation,   salaries  and  commissions  of  Consultant's

                              CONSULTING AGREEMENT

     AGREEMENT,  dated as of June 2, 1999,  by and  between  TECH  LABORATORIES,

Connecticut  corporation  with offices at 1055 Warlington  Blvd.,  Stanford,  CT
06901  ("Consultant").  This  Consulting  Agreement  between  Consultant and the
Company shall be hereinafter referred to as the "Agreement."

                              W I T N E S S E T H:

     WHEREAS,  the Company is engaged in the business of developing,  acquiring,
marketing and selling various products including,  among other things,  security
and   anti-terrorist   products  and   communication/networking   products  (the
"Products"); and

     WHEREAS,  the  Company  wishes  to engage  Consultant  to  provide  certain
financial and business development services; and

     WHEREAS,  Consultant  has  experience in providing the services the Company
wishes to have performed; and

     WHEREAS,  the  Company  and  Consultant  mutually  desire to enter  into an
Consulting Agreement with respect to Consultant's engagement by the Company;

     NOW, THEREFORE,  in consideration of the mutual covenants herein contained,
and for other good and  valuable  consideration  the  receipt of which is hereby
acknowledged, the Company and Consultant hereby agree as follows:

     1.   Engagement of Consultant.

          (a) The Company hereby engages Consultant to provide certain services,
     as described in Section 2.  Consultant  hereby accepts such engagement with
     the Company upon the terms and conditions  hereinafter set forth and agrees
     to perform the  services.  The parties agree that the  Consultant  shall be
     engaged by the Company as an independent  contractor on a consulting basis,
     and neither  Consultant,  nor any employee of Consultant shall be deemed an
     employee of the Company.

          (b)  Consultant  acknowledges  that  Company  is  entering  into  this
     Agreement in reliance upon the continued  employment  by  Consultant,  on a
     full-time basis, of Scott Coby ("Coby"). Consultant agrees that the failure
     of Coby to be  employed  by  Consultant,  including  by  reason of death or
     disability,  on a  full-time  basis  at any  time  during  the term of this
     Agreement  shall be deemed an  attempted  assignment  of this  Agreement by
     Consultant and subject to the provisions of Section 14(e) hereof.

     2. Services To Be Rendered.

          (a) During the term of this Agreement, Consultant shall furnish to the
     Company advice and recommendations with respect to the business and affairs
     of the Company in general,  and in connection  with the  development of the
     Company's  business  plan,  particularly  with  respect  to  the  financial
     requirements  of the Company in the  development of its business and in the
     negotiation and securing the necessary capital,  including debt and equity,
     and the marketing of the Company's  Products.  The Company shall, from time
     to time, request upon reasonable notice those services from Consultant that

     for the Products and (ii) customer development.

          (b)  Consultant  shall perform such services for the Company and other
     entities now or hereafter  affiliated  with the  Company.  Consultant  will
     devote  that amount of its time and effort to the affairs of the Company as

          (c) Consultant  shall perform the services at the  Consultant's or the
     Company's offices and, if applicable,  the business  locations of customers
     and  potential  customers  or at  such  other  location  as  is  reasonably
     necessary.

     be  extended  by the  mutual  agreement  of  the  Company  and  Consultant;

     Agreement,  this Agreement shall be automatically extended for one (1) year
     (the "Extension  Period") so long as neither Consultant nor the Company has
     provided written notice to the other party that this Agreement is not being
     renewed.  Such notice must be sent at least 90 days prior to the end of the
     Consulting Period.  Notwithstanding  anything herein to the contrary,  this
     Agreement  shall terminate in the event the Company has not raised $200,000
     in equity financing to fund its operations by June 1, 1999.

          (b) This Agreement may be terminated by Company, without notice, if at

                    obligations  under this  Agreement  and such  breach has not

                    dishonesty, including, without limitation, an act of theft;

               iii) Consultant becomes bankrupt or in the event that a receiving
                    order (or any analogous  order under any applicable  law) is
                    made  against it or in the event  that it makes any  general
                    disposition  or assignment for the benefit of its respective
                    creditors;

               iv)  The Consultant attempts to assign this Agreement without the
                    consent of the Company.

     Agreement  by  either  party,   for  any  reason  in  an  any  circumstance
     whatsoever, such termination shall be without prejudice to

     the rights of the Company,  in relation to, up to and including the date of
     termination;  and the  provisions  of Section 7 respecting  confidentiality
     shall  remain and  continue  in full force and effect  unless and until the
     Company,  in its absolute  discretion,  resolves  otherwise and so notifies
     Consultant in writing.

     11th:  This  lease  shall not be a li[ ] said  premises  in  respect to any
mortgages  that may  hereafter be placed upon said  premises.  The  recording of
s[uch]  mo[rtgage] or mortgages  shall have  preference  and  precedence  and be

lease to any such mortgage or mortgages. A refusal by the Tenant to execute such
instrument


<PAGE>


shall entitle the Landlord to the option of cancelling this lease,  and the term
hereof is hereby expressly [limi]ted accordingly.

     12th:  If the land and the premises [ ] the leased  premises are a part, or
any  portion  thereof,  shall be  taken  under  eminent  domain  or co[  ]nation
proceeding  [ ] if suit or other action  shall be  instituted  for the taking or
condemnation  thereof,  or if in lieu of p[ ]mal  [c]ondemnation  proceedings or
actions,  the Landlord  shall grant an option to purchase  and/or shall sell and
convey [ ] [s]aid premises or any portion thereof,  to the governmental or other
public authority,  agency,  body or public utility,  s[ ]g to take said land and
premises or any portion thereof, then this lease, at the option of the Landlord,
shall be  terminate  [and]  the term  hereof  shall  end as of such date [ ] the

[right]  to claim or be  entitled  to any  portion  of any  amount  which may be

are hereby  assigned to the  Landlord.  The Tenant agrees to execute and deliver
any instruments,  at the expense of the Landlord,  as may be deemed necessary or

portion  thereof.  The Tenant  covenants  and agrees to vacate the [ ] premises,
remove all the Tenant's  personal  property  therefrom  and deliver up peaceable
possessions [ ] to the Landlord [or] such other party designated by the Landlord
in the  aforementioned  notice.  Failure  by the  Tenant  [to  co]mply  with any
p[rovis]ions  of this clause shall  subject the Tenant to such costs,  expenses,
damages and losses  [as] the  Landlord  may incur by  rea[son]  of the  Tenant's
breach hereof.

practicable,  but the Tenant's  obligation to pay the rent  hereunder  shall not
cease.  [If, in] the o[pin]ion of the Landlord,  the premises be so  extensively
and substantially damaged as to render them untenantable,  then the [rent] shall
cease until such time as the premises shall be made  tenantable by the Landlord.
However,  if, in the opinion of the Landlord,  the premises be totally destroyed
or so  extensively  and  substantially  damaged  as  to  require  practically  a
rebuilding  thereof,  then  the  rent  shall  be  paid  up to the  time  of such
destruction  and then and from  henceforth this lease shall come to an [end.] In
no event  however,  shall the  provisions of this clause become  effective or be
applicable,  if the fire or other casualty and damage shall be the result of the
carelessness,  negligence  or  improper  conduct of the  Tenant or the  Tenant's
ag[ents,]  employees,  guests,  licensees,  invitees,  subtenants,  assignees or
successors. In such case, the Tenant's liability for the payment of the rent and
the  performance  of all the  covenants,  conditions  and  terms  hereof  on the
Tenant's part to be performed  shall  continue and the Tenant shall be liable to
the Landlord for the damage and l[oss]  suffered by the Landlord.  If the Tenant
shall  have been  insured  against  any of the risks  herein  covered,  then the
proceeds of such  insurance  shall be paid over to the Landlord to the extent of
the  Landlord's  costs and  expenses  to make the  repairs  hereunder,  and such
insurance   carriers   shall  have  no  recourse   against  the   Landlord   for
reimbursement.

     14th:  If the Tenant  shall fail or refuse to comply  with and  perform any
conditions and covenants of the within lease,  the Landlord may, if the Landlord
so elects, carry out and perform such conditions and covenants,  at the cost and
expense of the Tenant, and the said cost and expense shall be payable on demand,
or at the option of the Landlord  shall be added to the  installment of rent due
immediately  thereafter  but in no case later than one month after such  demand,
whichever occurs sooner, and shall be due and payable as such. This remedy shall
be in addition to such other  remedies as the  Landlord  may have  hereunder  by
reason of the breach by the Tenant of any of the  covenants  and  conditions  in
this lease contained.

     15th:  The Tenant  agrees  that the  Landlord  and the  Landlord's  agents,
employees or other representatives,  shall have the right to enter into and upon
the said premises or any part thereof, at all reasonable hours, for the purposes
of examining  the same or making such repairs or  alterations  therein as may be
necessary  for the safety and  preservation  thereof.  This clause  shall not be
deemed to be a covenant by the Landlord nor be construed to create an obligation
on the part of the Landlord to make such inspection or repairs.


<PAGE>


     16th: The Tenant agrees to permit the Landlord and the  Landlord's  agents,
employees or other  representatives  to show the premises to persons  wishing to
rent or purchase the same,  and Tenant  agrees that on and after six months next
preceding  the  expiration  of the term hereof,  the Landlord or the  Landlord's
agents,  employees or other representatives shall have the right to place notice
on the front of said  premises or any part  thereof,  offering  the premises for
rent or for sale;  and the  Tenant  hereby  agrees to permit  the same to remain
thereon without hindrance or molestation.

     17th:  If for any reason it shall be  impossible  to obtain  fire and other
hazard insurance on the buildings and improvements on the leased premises, in an
amount and in the form and in insurance  companies  acceptable  to the Landlord,
the Landlord  may, if the Landlord so elects at any time  thereafter,  terminate
this lease and the term hereof, upon giving to the Tenant fifteen days notice in
writing  of the  Landlord's  intention  so to do,  and upon the  giving  of such
notice, this lease and the term thereof shall terminate. If by reason of the use
to which the  premises  are put by the Tenant or  character  of or the manner in
which the  Tenant's  business  is carried on, the  insurance  rates for fire and
other  hazards  shall be  increase,  the Tenant  shall upon  demand,  pay to the
Landlord  as rent,  the amounts by which the  premiums  for such  insurance  are
increased.  Such payment shall be paid with the next  installment of rent but in
no case later than one month after such demand, whichever occurs sooner.

     18th: Any equipment,  fixtures,  goods or other property of the Tenant, not
removed by the Tenant upon the  termination of this lease, or upon any quitting,
vacating or  abandonment  of the  premises by the Tenant,  or upon the  Tenant's
eviction,  shall be considered as  abandonment  and the Landlord  shall have the
right,  without any notice to the Tenant,  to sell or  otherwise  dispose of the
same, at the expense of the Tenant,  and shall not be  accountable to the Tenant
for any part of the proceeds of such sale, if any.

     19th:  If there  should  occur any default on the part of the Tenant in the
performance of any conditions and covenants herein  contained,  or if during the
term hereof the  premises or any part  thereof  shall be or become  abandoned or
deserted,  vacated  or  vacant,  or should  the  Tenant be  evicted  by  summary
proceedings or otherwise, the Landlord, in addition to any other remedies herein
contained  or as may be  permitted  by law,  may  either by force or  otherwise,
without being liable for prosecution therefor, or for damages, re-enter the said
premises  and the same have and again  possess  and enjoy;  and as agent for the
Tenant or  otherwise,  re-let the  premises  and receive the rents  therefor and
apply the same, first to the payment of such expenses,  reasonable attorney fees
and costs, as the Landlord may have been put to in re-entering and  repossessing
the same and in making such repairs and  alterations  as may be  necessary;  and
second to the payment of the rents due hereunder. The Tenant shall remain liable
for such rents as may be in arrears and also the rents as may accrue  subsequent
to the re-entry by the  Landlord,  to the extent of the  difference  between the
rents reserved  hereunder and the rents, if any, received by the Landlord during
the remainder of the unexpired term hereof,  after deducting the  aforementioned
expenses, fees and costs; the same to be paid as such deficiencies arise and are
ascertained each month.

     20th:  Upon the  occurrence  of any of the  contingencies  set forth in the
preceding clause,  or should the Tenant be adjudicated a bankrupt,  insolvent or
placed in  receivership,  or should  proceedings be instituted by or against the
Tenant for  bankruptcy,  insolvency,  receivership,  agreement of composition or
assignment  for the benefit of creditors,  or if this lease or the estate of the
Tenant hereunder shall pass to another by virtue of any court proceedings,  writ

thereafter, at the Tenant's own cost and expense, cause such lien or liens to be
satisfied and  discharged of record  together with any Notices of Intention that

within 15 days of receipt of such notice  notify the  Landlord in writing of its
election  to purchase or not to  purchase  under the same  conditions  and terms
contained in the offer. Failure of the leasee to give written notice as required
herein shall deem to be a rejection  to purchase and this right shall  terminate
upon sale of the premises.

     38th:  The Tenant shall have the right to use all parking spaces located in
front of the building,  and shall be  responsible  for the  maintenance  of said
parking area and sidewalk area including the removal of snow, ice, and debris.

     5.3 Removal of Assets. Within 30 days following the Closing Date, Purchaser
shall cause any  Transferred  Assets  located in any of Seller's  premises to be
removed at the cost of Purchaser;  provided that if events beyond the reasonable
control of  Purchaser  prevent such  removal  during such 30 day period,  Seller
shall extend such period for a  reasonable  period.  Any such  removal  shall be
coordinated with Seller so as not to disrupt any production or other activity of
Seller.  Purchaser shall be liable for any damage caused to Seller's premises in
connection with such removal. Purchaser shall bear the risk of loss or damage of
any such Transferred Assets prior to such removal from Seller's premises, except
for  any  loss  or  damage  caused  by  Seller's  gross  negligence  or  willful
misconduct.

     5.4 No License of Seller's  Intellectual  Property Rights.  Nothing in this
Agreement or otherwise  shall be deemed to grant to, or establish in,  Purchaser
or any of its affiliates a license or other right to any trade name,  trademark,
service  mark or other  similar  right of Seller or its  affiliates,  except the
Trademark.  Without limiting the foregoing, (a) any references to "NORDX/CDT" or
any of its affiliates  (including any trade names or trademarks of Seller or its
affiliates) in or on any of the Transferred  Assets shall, at Purchaser's  cost,
be removed or permanently covered and (b) Purchaser shall not make references to
Seller or its  affiliates  (including  any  references  to the  limited  support
contemplated  by  Section  5.6) in any of its  marketing,  promotional  or other
activities  relating  to the  Transferred  Assets.  In the event that the action
required by clause (a) of the prior  sentence are not  possible  with respect to
any Transferred  Asset,  such Transferred  Asset shall be destroyed by Purchaser
at,  Purchaser's  cost and without  recourse to Seller or its  affiliates.  This
Section 5.4 shall not prevent press releases as provided in Section 6.6.

     5.5 License by Purchaser.  Effective on the Closing Date,  Purchaser grants
to Seller a non-exclusive,  royalty free license,  to use the Proprietary Rights
contained  in the  Transferred  Assets in  connection  with the  service  of any

Section 5.5 shall be for a period of 2 years from the Closing Date.

     5.6 Limited Post-Closing Service. To the extent the necessary resources are
available (including  knowledgeable  personnel) and it does not divert resources
from other  activities  of Seller (in each case,  determined  in  Seller's  sole
discretion), following the Closing


                                       -6-
<PAGE>


Date, Seller will provide Purchaser with post-installation service support using
the  Service  Lab assets for a period up to the date on which  Seller  offers to
sell the Service Lab assets to Purchaser in accordance  with Section 5.7,  which
service is intended to be required on an infrequent basis. Such assistance shall
be limited to service  that  Seller is able to be  performed  from its  premises
using  available  equipment.  Seller has no  obligation  to retain  personnel or
maintain  the Service Lab  assets.  Purchaser  shall pay Seller $75 per hour for
such  assistance  (provided  that such amount shall be adjusted in good faith to
reflect any increases in the costs of providing such  assistance).  Seller shall
have no liability to Purchaser or any third party for any such service provided,
and  Purchaser  shall  indemnify  and hold  Seller,  its  affiliates  and  their
officers,  directors,  employees,  agents and advisors harmless from any and all
losses, claims, actions, damages and liabilities,  and any and all out-of-pocket
costs and expenses,  including reasonable  attorneys' fees and disbursements and
costs of  investigation  (collectively,  "Losses")  arising  from or relating to
providing such service,  except to the extent a court of competent  jurisdiction
determines  that such  Losses were the result of Seller's  gross  negligence  or
willful misconduct.

     5.7 Purchase of the Service Lab assets; Access by Purchaser.

          (a)  Upon  Seller's   determination  that  any  commitment  (legal  or
     otherwise)  relating to DynaTrax  Products  sold or installed  prior to the
     Closing Date have ceased,  Seller will offer to sell the Service Lab assets
     (as  described  on Exhibit D) to Purchaser  (in such  condition or state as
     they shall then exist) for an amount  equal to $100;  provided  that Seller
     will offer such  assets no later than  December  31,  1999.  Purchaser  may
     accept  such offer  during  the 30 days after such offer is made,  and must
     close such purchase within 30 days following such  acceptance.  Any sale of
     such  assets  shall  be on an "as  is"  basis,  without  representation  or
     warranty  and  subject  to terms  similar  to those set forth  herein  with
     respect to the Transferred  Assets (excluding Section 5.6). Nothing in this
     Section 5.7 shall be deemed to require  Seller to service or  maintain  the
     Service Lab assets,  or make Seller liable for any loss or damage  relating
     thereto;  provided that in the event of a casualty  event  relating to such
     assets for which  Seller has third  party  insurance,  Seller  shall,  upon
     recovery  of any such  insurance  proceeds  (reduced  by the  amount of any
     self-insurance  or  deductible  or costs  associated  with such  recovery),
     either (i) use such insurance proceeds, to the extent available, to replace
     the Service Lab assets (which shall remain subject to this purchase option)
     or (ii) turn such proceeds over to the Purchaser,  net of the $100 purchase
     price.  Seller  shall  not be liable in the  event  such  proceeds  are not
     available for any reason.

          (b)  Following  the  Closing  Date and prior to the time  when  Seller
     offers to sell the Service Lab assets to  Purchaser,  Seller  shall  permit
     Purchaser  reasonable  access to such Service Lab assets so that  Purchaser
     may  service  its  customers.  Purchaser  shall  comply  with  such  rules,
     regulations and procedures  regarding security,  access,  number of persons
     having access,  visitors,  types of activities  which may be carried on and
     other reasonably related matters as designated by Seller from time to time.
     Seller shall not be responsible or liable for any of Purchaser's  employees
     or invitees (including any injury or death thereto) or any use or non-use


                                       -7-
<PAGE>


     of the Service Lab assets by Purchaser,  and Purchaser  shall indemnify and
     hold Seller harmless from any liability relating thereto.

                  5.8 Service Obligation of Tech Labs. At the request of Seller,
Purchaser will offer to any persons or entities that purchased DynaTrax Products
prior to the Closing Date service of such DynaTrax Products at a level, priority
and cost  commensurate  with service  provided to any purchasers or users of the
DynaTrax Products after the Closing Date.

     5.9 Retained Units.  The handling,  location and other matters  relating to
the Retained Units are described on Exhibit F.

     5.10 Prohibition on Hiring Seller's  Employees.  Without Seller's  consent,
for a period of two years  following  the date hereof,  Purchaser  shall not (a)
induce or attempt to induce any person  employed by Seller or its  affiliates on
the date hereof to leave the employ of Seller or such  affiliate,  or in any way
interfere  with  the  relationship  between  Seller  or such  affiliate  and any
employee  thereof or (b) hire directly or through  another entity any person who
is an employee of Seller or its affiliates on the date hereof.

     5.11  Indemnification.  Purchaser  shall  indemnify  and hold  Seller,  its
affiliates  and  their  officers,  directors,  employees,  agents  and  advisors
harmless  from any  Losses  arising  out of (a) the breach by  Purchaser  of any
covenant,  representation  or warranty set forth herein or (b) any activities of
Purchaser or its affiliates in connection with the DynaTrax  Product,  including
marketing  efforts,  sales,  installations  or other  activities of Purchaser in
connection with the DynaTrax Product, or any DynaTrax Product sold by Purchaser.
Seller shall  indemnify and hold  Purchaser,  its affiliates and their officers,
directors,  employees,  agents and advisors harmless from any Losses arising out
of (a) the breach by Seller of any  covenant,  representation  or  warranty  set
forth herein or (b) any Unassumed Liability.

     5.12 Litigation  Support. In the event and for so long as any party to this
Agreement is actively  contesting  or defending  against any third party action,
suit, proceeding, hearing, investigation,  charge, complaint, claim or demand in
connection with any fact, situation,  circumstance, status, condition, activity,
practice,  plan,  occurrence,  event,  incident,  action,  failure  to  act,  or
transaction, with respect to the Transferred Assets, the party not so contesting
or defending agrees to (a) use reasonable  efforts to make available  employees,
as  reasonably  necessary,  to  provide  testimony,  to be  deposed,  to  act as
witnesses and to assist counsel and (b) provide  reasonable  access to its books
and records  relating to the  Transferred  Assets (to the extent it has any such
books and records) as may be reasonably necessary in connection with the defense
or contest,  all at the sole cost and  expense of the  contesting  or  defending
party  (including  the cost of any legal  advice or  support in  providing  such
access or information).

     5.13  Exclusivity.  Neither  Seller  nor  any of its  affiliates  or  their
employees,  officers,  directors or agents will solicit, initiate,  encourage or
discuss any proposal or offer from any person (other than Purchaser) relating to
the sale of the  Transferred  Assets,  or provide any  confidential  information
relating thereto after the date hereof and until the termination of this


                                       -8-

25 completed DynaTrax units will be retained by Seller on Closing Date; provided
that in the event Retained Units are sold prior to the Closing Date, such number
shall be reduced by the number of such sold units. The remaining  Retained Units
shall be held by Purchaser for the benefit of the Seller (provided such units do
not need to be fully assembled until such time as they are shipped to the Seller
and provided further that Purchaser may substitute newly  manufactured  DynaTrax
units for units held on behalf of Seller).

Promptly  following  notice from Seller  that  Seller has sold  DynaTrax  units,
including  sales  prior to the Closing  Date  (which  notice does not need to be
given  immediately  following  a sale),  Purchaser  shall,  without  any cost to
Seller,  ship to Seller a number of completed DynaTrax units equal to the number
of units sold by Seller,  but in no event more than the total number of Retained
Unites held for the benefit of Seller by Purchaser  (i.e., the 50 units less the
number  sold by Seller  prior to the  Closing  Date less the number  retained by
Seller on the Closing Date).  Seller's request for replacement  shall be made at
reasonable  times and with  reasonable  notice taking into account the demand of
Seller and Purchaser and the completed  DynaTrax unit inventory levels of Seller
and Purchaser.

Purchaser shall, without charge,  provide to Seller and Seller's purchasers with
its customary warranty and service.

On June 30, 2000,  Purchaser may purchase from Seller any unsold  Retained Units
(including  any units that are held by Purchaser on behalf of Seller) for a cash
purchase  price of $5,000 per unit,  on an "as is basis." In the event that such
units are not purchased by Purchaser, the number of units then held by Purchaser
shall be promptly delivered to Seller in a completed form.


                                                                   Exhibit 10.12

                           Incentive Stock Option Plan
                                       of
                             TECH LABORATORIES, INC.

                                   ----------

1.   PURPOSE.

     This  Incentive  Stock Option Plan (the "Plan") is intended as an incentive
for and encouragement of stock ownership by certain officers, directors, and key
employees  of Tech  Laboratories,  Inc.  (the  "Corporation"),  so that they may
acquire  or  increase  their   proprietary   interest  in  the  success  of  the
Corporation,  and to  encourage  them to remain  in its  employ.  It is  further
intended that Options issued  pursuant to this Plan shall  constitute  qualified
incentive  stock  options  within the  meaning of Section  422A of the  Internal
Revenue Code, as amended (the "Code").

2.   ADMINISTRATION.

     The Plan shall be  administered  by a committee  appointed  by the Board of
Directors of the Corporation (the  "Committee").  The Committee shall consist of
two or more  members  of the  Corporation's  Board of  Directors.  The  Board of
Directors  may, from time to time,  remove  members from, or add members to, the
Committee.  The Committee  shall select one of its members as  Chairperson,  and
shall hold  meetings at such times and places as it may  determine.  Action by a
majority  of the  Committee  shall  be the  valid  acts  of the  Committee.  The
Committee shall, from time to time at its discretion, consult with management of
the Corporation and make  recommendations to the Board of Directors with respect
to the officers,  directors,  and key employees who shall be granted options and
the amount of stock to be optioned to each.

     The  interpretation  and construction by the Committee of any provisions of
the Plan or of any  Option  granted  under it  shall be final  unless  otherwise
determined by the Board of Directors. No member of the Board of Directors or the
Committee  shall be liable  for any action or  determination  made in good faith
with respect to the Plan or any Option granted under it.

3.   ADMINISTRATION.

     The persons who shall be eligible  to receive  Options  shall be  officers,
directors,  and key  executive  employees  of the  Corporation  as the  Board of
Directors shall select from time to time among those nominated by the Committee.
An Optionee may hold more than one Option,  but only on the terms and subject to
the restrictions  hereafter set forth. No person shall be eligible to receive an
Option  for a  larger  number  of  shares  than  is  recommended  for him by the
Committee.

4.   STOCK.

     The stock  subject  to the  Options  shall be  shares of the  Corporation's
authorized  but  unissued or  reacquired  par value $.01 per share  common stock
hereafter  sometimes  called Common Stock.  The aggregate number of shares which
may be issued  pursuant to this Plan shall be subject to  adjustment as provided
in Article 5(I) of the Plan.

     In the event  that any  outstanding  Option  under the Plan for any  reason
expires  or  is  terminated,  the  shares  of  Common  Stock  allocable  to  the
unexercised  portion of such Option may again be subject to an Option  under the
Plan.


<PAGE>


5.   TERMS AND CONDITIONS OF OPTIONS.

     Stock Options granted pursuant to the Plan shall be authorized by the Board
of Directors  and shall be evidenced by agreements in such form as the Committee
shall from time to time  approve,  which  agreements  shall  comply  with and be
subject to the following terms and conditions:

     A.   Number of Shares.

          (1) Each Option shall state the number of shares to which it pertains.

          (2) If  the  aggregate  fair  market  value  of the  shares  of  stock
     (determined  as of the time of grant of such  option(s),  with  respect  to
     which  incentive  stock  options are  exercisable  for the first time by an
     optionee  during any calendar year (under all such plans of the Corporation
     and its parent and subsidiary corporations, if any)) exceeds $100,000, then
     only the first  $100,000  of such  shares so  purchased  will be treated as
     exercised  under this Plan, and any excess over $100,000 so purchased shall
     be treated as options  which are not  incentive  stock  options;  provided,
     however,  that this rule shall be applied by taking options into account in
     the order or sequence in which they were granted.

          (3) For purposes of computing the annual  limitation,  the fair market
     value of Common Stock of the  Corporation  granted under this Plan shall be
     aggregated with the fair market value of any other stock of the Corporation
     granted  to such  optionee  under  this  Plan or any  other  plan or  plans
     maintained by the Corporation.

     B.   Option Price.

     Each Option shall state the Option price, which shall not be less than 100%
of the fair market value of the shares of Common Stock of the Corporation on the
date of the  granting of the Option;  provided,  however,  that if the Option is
granted to an Optionee  who, at the time of the grant,  owns (as  determined  in
accordance with Section 425(d) of the Code) stock of the Corporation  possessing
more  than  10% of the  total  voting  power  of all  classes  of  stock  of the
Corporation,  then the  option  price  shall be not less  than  110% of the fair
market value of the shares of Common Stock of the Corporation on the date of the
granting of the Option.

     During  such time as such stock is not  listed  upon an  established  stock
exchange or exchanges or NASDAQ System, the fair market value per share shall be
the mean  between  dealer  "bid" and "ask"  process of the  Common  Stock in the
over-the-counter  market on the day the Option is  granted,  as  reported by the
National Association of Securities Dealers,  Inc. If the stock is listed upon an
established stock exchange or exchanges or NASDAQ System, such fair market value
shall be deemed to be the  highest  closing  price of the  Common  Stock on such
stock  exchange or  exchanges  or system the day the Option is granted or, if no
sale of the  Corporation's  Common  Stock  shall  have  been  made on any  stock
exchange or such system on that day,  on the next  preceding  day on which there
was a sale of such stock. If the stock is neither listed on an established stock
exchange or the NASDAQ System, nor traded over-the-counter,  the Committee shall
determine  such fair market  value under the general  principles  of valuing the
stock of  corporations  whose  shares are not  publicly  traded.  Subject to the
foregoing,  the Board of  Directors  and the  Committee  fixing the Option price
shall have full authority and discretion and be fully protected in doing so.


                                       -2-
<PAGE>


     C.   Medium and Time of Payment.

     The Option  price shall be payable in cash or by check upon the exercise of
the Option;  provided,  however, the Board of Directors, in its sole discretion,
may accept other forms of payment, including, but not limited to, other stock of
the Corporation then owned by Optionee.

     D.   Term and Exercise of Options.

          (1) Each Option shall specify the dates upon which such Options can be
     exercised,  and shall designate the maximum number of shares granted by the
     Option that can be exercised on such dates.  To the extent that the maximum
     number of shares permitted to be exercised on such date or dates are not so
     exercised, such shares may be so exercised at any subsequent date not later
     than ten (10) years after the Option was granted;  provided,  however, that
     no Option granted to an Optionee who, at the time of the grant,  owns stock
     of the  Corporation (as determined in accordance with Section 425(d) of the
     Code)  possessing more than 10% of the total voting power of all classes of
     stock of the  Corporation,  shall be  exercisable  more than five (5) years
     after such Option was granted.

          (2)  During  the  lifetime  of  the  Optionee,  the  Option  shall  be
     exercisable only by him and shall not be assignable or transferable by him,
     and no other person shall acquire any rights herein.

     E.   Termination of Employment Except Death.

          (1) In the event that an  Optionee  shall  voluntarily  terminate  his
     employment with the  Corporation,  other than as a result of his death, and
     shall no longer be in its employ,  subject to the condition  that no Option
     shall be  exercisable  after the expiration of ten (10) years from the date
     it is granted (or after the  expiration  of five (5) years if such  shorter
     period is  applicable),  such Optionee shall have the right to exercise the
     Option  at any  time  within  five (5) days  prior to such  termination  of
     employment,  but only to the extent his right to  exercise  such Option had
     accrued as specified in such Option and had not  previously  been exercised
     at the date of his termination from employment.  Whether  authorized leaves
     of absence or absence for military or governmental service shall constitute
     termination  of  employment,  for  the  purposes  of  the  Plan,  shall  be
     determined by the Committee,  which determination,  unless overruled by the
     Board of Directors, shall be final and conclusive.

          (2) In the event that an Optionee shall have his  employment  with the
     Corporation  involuntarily terminated for reasons other than his death, any
     Option  held by such  employee  and not  exercised  as of the  date of such
     termination may be exercised within 30 days thereof to the extent currently
     exercisable otherwise they shall be cancelled and no longer exercisable.

          (3) The Board of  Directors,  at its sole  discretion,  may redeem any
     accrued but unexercised Options of an employee whose employment with it has
     terminated  by paying to such  employee an amount  equal to the  difference
     between the Option  price and the then fair market  value of the stock,  as
     determined in accordance with Article 5(B) of the Plan.

     F.   Death of Optionee and Transfer of Option.

     If the Optionee shall die while in the employ of the  Corporation and shall
not have fully exercised the Option, the Option may be exercised, subject to the
condition that no Option shall be  exercisable  after the expiration of ten (10)
years from the date it is granted (or after the expiration of five (5) years, if
such shorter  period is  applicable),  at any time within one (1) year after the
Optionee's death, by the executors,  administrators, or personal representatives
of the Optionee or by bequest or inheritance,


                                       -3-
<PAGE>


but only to the extent that the  Optionee's  right to  exercise  such Option had
accrued  as  specified  in the  Option  at the  time  of his  death  and had not
previously been exercised.

     No Option shall be  transferable  by the Optionee other than by will or the
applicable laws of descent and distribution.

     G.   Adjustment of Shares.

     Subject to any required action by the stockholders, the number of shares of
Common Stock covered by each outstanding Option, and the price per share thereof
of each such  Option,  shall be  proportionately  adjusted  for any  increase or
decrease  in the  number of issued  shares  of Common  Stock of the  Corporation
resulting  from a  subdivision  or  consolidation  of shares or the payment of a
stock  dividend (but only on the Common Stock) or any other increase or decrease
in the number of such shares effected  without receipt of  consideration  by the
Corporation.

     Subject to any  required  action by the  stockholders,  if the  Corporation
shall  be  the  surviving  corporation  in any  merger  or  consolidation,  each
outstanding  Option  shall  pertain  to and apply to the  securities  to which a
holder of the number of shares of Common Stock  subject to the Option would have
been entitled.  A dissolution  or liquidation of the  Corporation or a merger or
consolidation in which the Corporation is not the surviving  corporation,  shall
cause  each  outstanding  Option  to  terminate;  provided,  however,  that each
Optionee  shall,  in such  event,  have  the  right  immediately  prior  to such
dissolution or liquidation,  or merger or consolidation in which the Corporation
is not the  surviving  corporation,  to exercise  limitations  contained  in the
Option.

     In the  event of a  change  in the  Common  Stock  of the  Corporation,  as
presently constituted, which is limited to a change of all its authorized shares
in the same number of shares with the stated par value, the share resulting from
any such change shall be deemed to be the Common Stock subject to the Option.

     Except  as  hereinbefore  expressly  provided  in this  Article  5(H),  the
Optionee  shall  have no rights by reason of  subdivision  or  consolidation  of
shares of stock of any class or the  payment of any stock  dividend or any other
increase  or decrease in the number of shares of stock of any class or by reason
of any dissolution,  liquidation, merger or consolidation, or spin-off of assets
or stock of another  corporation,  and any issue by the Corporation of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall not affect the  number or price of shares of Common  Stock  subject to the
Option.

     The grant of an Option pursuant to the Plan shall not affect in any way the
right  or  power  of the  Corporation  to make  adjustments,  reclassifications,
reorganizations  or changes of its capital or business  structure or to merge or
to consolidate or to dissolve, liquidate or sell, or transfer all or any part of
its business or assets.

     H.   Rights as a Stockholder.

     An  Optionee  or a  transferee  of an  Option  shall  have no  rights  as a
stockholder  with respect to any shares  covered by his Option until the date of
the issuance of a stock  certificate to him for such shares. No adjustment shall
be made for dividends (ordinary or extraordinary,  whether in case,  securities,
or other property) or distributions or other rights for which the record date is
prior to the date such  stock  certificate  is  issued,  except as  provided  in
Article 5(G) hereof.

     I.   Modification, Extension, and Renewal of Options.

     Subject to the terms and conditions and within the limitations of the Plan,
the Board of Directors may modify,  extend, or renew outstanding Options granted
under the Plan,  or accept the surrender of  outstanding  Options (to the extent
not  theretofore  exercised)  and  authorize  the  granting  of new  Options  in
substitutions  therefor (to the extent not theretofore  exercised).  However, no
modifications of an Option shall, without the consent of the Optionee,  alter or
impair any rights or obligations under any Option theretofore  granted under the
Plan.

     J.   Investment Purpose.

     Each  Option  under the Plan  shall be granted  on the  condition  that the
purchases of Common Stock thereunder shall be for investment  purposes,  and not
with a view to resale or distribution  except that in the event the Common Stock
subject  to such  Option is  registered  under the  Securities  Act of 1933,  as
amended,  or in the event a resale of such stock without such registration would
otherwise be permissible,  such condition shall be inoperative if in the opinion
of  counsel  for the  Corporation  such  condition  is not  required  under  the
Securities Act of 1933 or any other applicable law,  regulation,  or rule of any
governmental  agency.  Each Optionee shall give to the Corporation an investment
letter, in a form prescribed by the Board of Directors, as a condition precedent
to the issuance of certificates representing shares exercised by such Optionee.

     K.   Other Provisions.

     The Option  agreements  authorized  under the Plan shall contain such other
provisions, including, without limitation, restrictions upon the exercise of the
option,  as the  Committee and the Board of Directors of the  Corporation  shall
deem advisable.  Any such Option  agreement  shall contain such  limitations and
restrictions upon the exercise of the Option,  and the amount of such Option, as
shall be necessary in order that such Option will be an "incentive stock Option"
as defined in Section 422A of the Code or to conform to any change in the law.

6.   TERM OF PLAN.

     Options  may be  granted  pursuant  to the Plan from time to time  within a
period of ten years  from the date the Plan is  adopted  or the date the Plan is
approved by the Stockholders, whichever is earlier.

7.   INDEMNIFICATION OF COMMITTEE.

     In addition  to such other  rights of  indemnification  as they may have as
directors or as members of the Committee,  the members of the Committee shall be
indemnified  by the  Corporation  against  the  reasonable  expenses,  including
attorney's  fees,  actually  and  necessarily  incurred in  connection  with the
defense of any action,  suit, or  proceeding,  or in connection  with any appeal
therein,  to which  they or any of them may be a party by reason  of any  action
taken or  failure  to act  under or in  connection  with the Plan or any  Option
granted  thereunder,  and against all amounts paid by them in settlement thereof
(provided such settlement is approved by independent  legal counsel  selected by
the  Corporation)  or paid by them in  satisfaction  of a  judgment  in any such
action, suit, or proceeding,  except in relation to matters as to which it shall
be adjudged in such action,  suit, or proceeding,  that such Committee member is
liable for negligence or misconduct in the  performance of his duties;  provided
that within 60 days after institution of any such action,  suit, or proceeding a
Committee  member shall in writing offer the  Corporation the opportunity at its
own expense, to handle and defend the same.


                                       -5-
<PAGE>


8.   AMENDMENT OF THE PLAN.

     The Board of Directors of the Corporation  may, insofar as permitted by the
law,  from time to time,  with  respect to any share at the time not  subject to
Options,  suspend or  discontinue  the Plan or revise or amend it in any respect
whatsoever except that without approval of the stockholders, no such revision or
amendment  shall  change  the number of shares  subject to the Plan,  change the
designation of the class of employees eligible to receive Options,  decrease the
price at which  Options may be granted,  remove the  administration  of the Plan
from the Committee, or render any member of the Committee eligible to receive an
Option  under the Plan while  serving  thereon.  Furthermore,  the Plan may not,
without  the  approval of the  stockholders,  be amended in any manner that will
cause  Options  issued  under it to fail to meet the  requirements  of incentive
stock Options as defined in Section 422A of the Code.

9.   APPLICATION OF FUNDS.

     The  proceeds  received by the  Corporation  from the sale of Common  Stock
pursuant to Options will be used for general corporate purposes.

10.  NO OBLIGATION TO EXERCISE OPTION.

     The granting of an Option shall impose no  obligation  upon the Optionee to
exercise such Option.

11.  EFFECTIVE DATE; APPROVAL OF STOCKHOLDERS.

     The Plan shall not take effect until  approved by the holders of a majority
of the  outstanding  shares of Common Stock of the  Corporation,  which approval
must occur within the date the Plan is adopted by the Board of Directors.

                                   ----------
                        Incentive Stock Option Agreement
                                   ----------



     Agreement  made this  ________  day of  ____________,  1995,  between  TECH
LABORATORIES,  INC.,  a New  Jersey  corporation  (the  "Company"  or "TLI") and
_______________________,  an employee (or  independent  director) of the Company
residing  at   __________________________________________   (the  "Employee"  or
"Director").

     NOW,  THEREFORE,  in  consideration  of the  premises,  it is agreed by and
between the parties hereto as follows:

     1. Grant of Option.

     The Company hereby grants the Employee  (Director) the right  privilege and
Option to purchase up to  __________  of its shares of Common  Stock,  par value
$____ per  share,  at an  exercise  price of $_____  per share in the manner and
subject to the conditions provided herein and in its Incentive Stock Option Plan
(the "Plan").

     2. Times of Exercise.

     The Option  covered by this  Agreement  may be  exercised  by the  Employee
(Director) from _________, 1999, until ___________, ____, in whole or in part or
until its expiration or  termination  as provided  herein or in the Plan. In the
case of an Employee,  the option vests and may only be  exercisable at a rate no
greater than 33 1/3% each continuous year in which the Employee is employed on a
full-time  basis by the Company.  (In the case of an independent  Director,  the
option vests and may only be  exercisable  after one full year's  membership  on
TLI's Board of Directors.)

     3. Method of Exercise.

     The Option shall be exercised by delivering a written notice to a member of
the Stock Option Committee at the Company's  principal  offices,  accompanied by
the Employee's (Director's) personal check in the appropriate amount for payment
of the exercise  price for the number of shares of Common Stock of TLI specified
to be purchased.  The written  notice shall indicate such number of shares to be
purchased and the total exercise price  applicable  thereto.  The Company shall,
within 30 days of receiving  such notice and the Employee's  (Director's)  check
covering  the  exercise  price,  deliver  a stock  certificate(s).  The  date of
delivery of such stock certificate(s) may be extended by mutual agreement of the
Company and the Employee  (Director) or due to any law or  regulation  which may
require the Company to take  action with  respect to the shares  covered by such
notice prior to issuance thereof.

     4. Termination of Option.

     Except as otherwise state herein, the Option, to the extent that it has not
been  exercised,  shall  terminate  upon the  occurrence of any of the following
events:

     (A) Within 5 days after the Employee (Director)  voluntarily terminates his
employment  with the  Company but only to the extent that such Option has become
exercisable as of the date of termination of such the Employee (Director);


<PAGE>


     (B) Within 30 days if such  employment  was  terminated on a  non-voluntary
basis  other  than  death but only to the  extent  that such  Option  has become
exercisable as of the date of termination of such the Employee (Director);

     (C) Within one year after the Employee's  (Director's)  death by his or her
executor, administrator, or personal representative, but only to the extent that
such Option has become exercisable s of the date of death of such employee; or

     (D) _______,  __ (representing  the expiration of five years from the grant
of this Option).

                  Questions,  including,  but not limited to, such  voluntary or
non-voluntary  terminations,   the  disability  of  the  Employee,  and  related
treatment hereunder, shall be determined by the Stock Option Committee.

     5. Reclassification, Consolidation, or Merger.

     This Option is subject to certain anti-dilution provisions set forth in the
Plan.

     6. Rights Prior to Exercise of Option.

     This Option is non-assignable and non-transferable by the Employee,  except
in the  event of his or her  death as  specified  in the  Plan  and  during  the
Employee's (Director's) lifetime is exercisable only by him or her. The Employee
(Director)  shall have no rights as a stockholder  of the Company merely because
he or she has been granted this Option. Such rights only accrue upon exercise of
the Option, in whole or in part, payment of the appropriate  exercise price, and
issuance and delivery of the underlying shares as provided in this Agreement.

     7. Restrictions on Dispositions.

     In order to realize the tax benefits  allowed under  Section  424(a) of the
Internal  Revenue Code of 1986, as amended  regarding any gains derived from the
sale of the shares  underlying this Option, no disposition of such shares may be
made by the  Employee  (Director)  within  two (2)  years  from  the date of the
granting of this Option or within one (1) year after the transfer of such shares
to the Employee (Director) and the Employee (Director) must remain in the employ
of the Company from the time the Option is granted until three (3) months before
its  exercise,  and in the case of his or her  disability,  twelve  (12)  months
before its exercise.

     All shares acquired by the Employee  (Director) shall be deemed  restricted
securities as that term is defined under the  Securities Act of 1933, as amended
(the "Act"),  and may not be sold or transferred  unless certain  conditions are

     4. REGISTRATION UNDER THE SECURITIES ACT.

          (a)  "Piggyback  Registration".  If the  Company  shall  determine  to
     proceed with the actual preparation and filing of a registration  statement
     under the Securities Act in connection  with the proposed offer and sale of
     any of its  securities  by it or any of its security  holders in an initial
     public offering or otherwise  (other than a registration  statement on Form
     S-4 or S-8), then the Company will give written notice of its determination
     to all record holders of the Option and/or any Shares,  as the case may be.
     Upon the written  request from any record holder or holders of an aggregate
     of more than 50% of the Options and Shares,  considered  in the  aggregate,
     within 20 days  after  receipt of any such  notice  from the  Company,  the
     Company  will,  except as  herein  provided,  cause  all such  Shares to be
     included in such  registration  statement,  all to the extent  requisite to
     permit the sale or other  disposition by the prospective  seller or sellers
     of the Shares to be so registered;  provided,  further, that nothing herein
     shall  prevent the Company  from,  at any time,  abandoning or delaying any
     registration.  If any  registration  pursuant to this Section 4(a) shall be
     underwritten  in whole or in part, the Company will require that the Shares
     requested  for  inclusion  pursuant to this Section 4(a) be included in the
     underwriting  on the same terms and conditions as the securities  otherwise
     being sold through the underwriters.

          The obligation of the Company under this Section 4(a) shall be limited
     to one registration statement.

          (b) Registration  Procedures.  If and whenever the Company is required
     by the provisions of Section 4(a) to effect the registration of Registrable
     Securities under the Securities Act, the Company will:

               i) prepare and file with the SEC a  registration  statement  with
          respect  to such  securities,  and use its best  efforts to cause such
          registration statement to become and remain effective until the Shares
          are freely salable without the volume limitations of Rule 144;

               ii)  prepare  and  file  with  the SEC  such  amendments  to such
          registration  statement and  supplements to the  prospectus  contained
          therein  as may be  necessary  to  keep  such  registration  statement
          effective  until the  Shares are freely  saleable  without  the volume
          limitations of Rule 144;

               iii)  furnish  to the  security  holders  participating  in  such
          registration   and  to  the   underwriters  of  the  securities  being
          registered  such  reasonable  number  of  copies  of the  registration
          statement,  preliminary  prospectus,  final  prospectus and such other
          documents  as such  underwriters  may  reasonably  request in order to
          facilitate the public offering of such securities;

               iv) use its best  efforts to register  or qualify the  securities
          covered by such registration  statement under such state securities or
          blue sky laws of such jurisdictions as such


                                       -2-

<PAGE>



          participating holders may reasonably request in writing within 20 days
          following the original filing of such registration  statement,  except
          that the  Company  shall not for any  purpose be required to execute a
          general  consent to service of process or to qualify to do business as
          a  foreign  corporation  in  any  jurisdiction  wherein  it is  not so
          qualified;

               v)  notify   the   holders  of  Shares   participating   in  such
          registration,  promptly after it shall receive notice thereof,  of the
          time  when such  registration  statement  has  become  effective  or a
          supplement  to any  prospectus  forming  a part of  such  registration
          statement has been filed;

               vi) notify  such  holders  promptly of any request by the SEC for
          the  amending  or  supplementing  of such  registration  statement  or
          prospectus or for additional information;

               vii) prepare and file with the SEC,  promptly upon the request of
          any such holders,  any amendments or supplements to such  registration
          statement  or  prospectus  which,  in the  opinion of counsel for such
          holders  (and  concurred in by counsel for the  Company),  is required
          under the  Securities Act or the rules and  regulations  thereunder in
          connection with the distribution of Common Stock by such holder;

               viii) prepare and promptly file with the SEC and promptly  notify
          such  holders of the filing of such  amendment or  supplement  to such
          registration  statement or  prospectus  as may be necessary to correct
          any statements or omissions if, at the time when a prospectus relating
          to such  securities is required to be delivered  under the  Securities
          Act,  any event  shall have  occurred  as the result of which any such
          prospectus or any other  prospectus as then in effect would include an
          untrue statement of a material fact or omit to state any material fact
          necessary  to  make  the  statements  therein,  in  the  light  of the
          circumstances in which they were made, not misleading; and

               ix) advise such holders,  promptly  after it shall receive notice
          or obtain knowledge thereof,  of the issuance of any stop order by the
          SEC suspending the effectiveness of such registration statement or the
          initiation  or  threatening  of any  proceeding  for that  purpose and
          promptly  use its best  efforts to prevent  the  issuance  of any stop
          order or to obtain its withdrawal if such stop order should be issued.

          (c) Expenses.

               i) With respect to the registration  required pursuant to Section
          4(a) or 4(b) hereof, all fees, costs and expenses of and incidental to
          such  registration,  inclusion  and public  offering (as  specified in
          paragraph  (ii) below) in connection  therewith  shall be borne by the
          Company, provided, however, that any securityholders  participating in
          such registration  shall bear their pro rata share of the underwriting
          discount and commissions and transfer taxes.

               ii) The fees,  costs and expenses of  registration to be borne by
          the Company as provided in paragraph (i) above shall include,  without
          limitation,   all  registration,   filing,  and  NASD  fees,  printing
          expenses,  fees and  disbursements  of counsel and accountants for the
          Company,  and all legal fees and  disbursements  and other expenses of
          complying with state securities or blue sky laws of any  jurisdictions
          in  which  the  securities  to be  offered  are to be  registered  and
          qualified (except as provided in (i) above). Fees and disbursements of
          counsel and accountants for the selling  securityholders and any other
          expenses  incurred  by  the  selling   securityholders  not  expressly
          included above shall be borne by the selling securityholders.

          (d) Indemnification.

               i) The Company will  indemnify  and hold  harmless each holder of
          Shares which are included in a registration  statement pursuant to the
          provisions of Section 4(a) or 4(b) hereof, its directors and officers,
          and any underwriter (as defined in the Securities Act) for such holder
          and each person,  if any, who controls such holder or such underwriter
          within the meaning of the Securities  Act, from and against,  and will
          reimburse such holder and each such underwriter and controlling person
          with respect to, any and all loss, damage, liability, cost and expense
          to which such holder or any such underwriter or controlling person may
          become subject under the Securities Act or otherwise,  insofar as such
          losses,  damages,  liabilities,  costs or  expenses  are caused by any
          untrue  statement or alleged  untrue  statement  of any material  fact
          contained in such  registration  statement,  any prospectus  contained
          therein or any amendment or supplement thereto, or arise out of or are
          based  upon the  omission  or  alleged  omission  to state  therein  a
          material fact  required to be stated  therein or necessary to make the
          statements  therein,  in light of the circumstances in which they were
          made, not misleading;  provided, however, that the Company will not be
          liable  in any such case to the  extent  that any such  loss,  damage,
          liability,  cost or expenses  arises out of or is based upon an untrue
          statement or alleged untrue  statement or omission or alleged omission
          so made in conformity with information  furnished by such holder, such
          underwriter or such controlling person in writing specifically for use
          in the preparation thereof.

               ii) Each holder of Shares included in a registration  pursuant to
          the provisions of Section 4(a) hereof will indemnify and hold harmless
          the Company,  its directors and officers,  any controlling  person and
          any underwriter from and against,  and will reimburse the Company, its
          directors and officers,  any  controlling  person and any  underwriter
          with respect to, any and all loss, damage,  liability, cost or expense
          to which the Company or any controlling  person and/or any underwriter
          may become subject under the  Securities Act or otherwise,  insofar as
          such losses, damages, liabilities, costs or expenses are caused by any
          untrue  statement or alleged  untrue  statement  of any material  fact
          contained in such  registration  statement,  any prospectus  contained
          therein or any amendment or supplement thereto, or arise out of or are
          based  upon the  omission  or  alleged  omission  to state  therein  a
          material fact  required to be stated  therein or necessary to make the
          statements  therein,  in light of the circumstances in which they were
          made,  not  misleading,  in each case to the  extent,  but only to the
          extent,  that such untrue  statement  or alleged  untrue  statement or
          omission  or  alleged  omission  was so made in  reliance  upon and in
          strict conformity with written  information  furnished by or on behalf
          of such holder specifically for use in the preparation thereof.

               iii) Promptly after receipt by an  indemnified  party pursuant to
          the provisions of paragraph (i) or (ii) of this Section 4(d) of notice
          of the  commencement of any action involving the subject matter of the
          foregoing indemnity provisions such indemnified party will, if a claim
          thereof is to be made against the  indemnifying  party pursuant to the
          provisions  of  said  paragraph  (i)  or  (ii),  promptly  notify  the
          indemnifying party of the commencement thereof; but the omission to so
          notify the  indemnifying  party will not relieve it from any liability
          which it may have to any  indemnified  party otherwise than hereunder.
          In case such action is brought  against any  indemnified  party and it
          notifies  the  indemnifying  party of the  commencement  thereof,  the
          indemnifying party shall have the right to participate in, and, to the
          extent that it may wish,  jointly  with any other  indemnifying  party
          similarly  notified,  to assume  the  defense  thereof,  with  counsel
          satisfactory to such  indemnified  party,  provided,  however,  if the
          defendants in any action  include both the  indemnified  party and the
          indemnifying  party and the  indemnified  party shall have  reasonably
          concluded  that  there may be legal  defenses  available  to it and/or
          other  indemnified  parties which are different from or in addition to
          those available to the indemnified


                                       -4-

<PAGE>



          party,  or if there is a conflict  of  interest  which  would  prevent
          counsel  for  the  indemnifying   party  from  also  representing  the
          indemnified  party, the indemnified party or parties have the right to
          select  separate  counsel to participate in the defense of such action
          on behalf of such indemnified party or parties.  After notice from the
          indemnifying  party to such  indemnified  party of its  election so to
          assume the defense thereof,  the indemnifying party will not be liable
          to such indemnified party pursuant to the provisions of said paragraph
          (i) or (ii) for any legal or other  expense  subsequently  incurred by
          such  indemnified  party in connection  with the defense thereof other
          than  reasonable  costs of  investigation,  unless (1) the indemnified
          party shall have employed counsel in accordance with the provisions of
          the  preceding  sentence,  (2) the  indemnifying  party shall not have
          employed  counsel  satisfactory to the indemnified  party to represent
          the indemnified party within a reasonable time after the notice of the
          commencement  of the  action  or  (iii)  the  indemnifying  party  has
          authorized the employment of counsel for the indemnified  party at the
          expense of the indemnifying party.

     5.  TRANSFERABILITY  OF  OPTION.  This  Option may only be  transferred  in
compliance  with the Act.  The  Company may  request in its sole  discretion  an
opinion of counsel from the transferor  prior to any transfer to the effect that
the  Option  may be  transferred  by the  transferor  without  violation  of the
registration  provision of the Act.  Transferor  shall notify the Company of any
proposed  transfer.  The  terms  of this  Agreement  shall be  binding  upon the
executors, administrators, heirs, successors, and assigns of the Optionee.

     6. TERM OF OPTION.  This Option may be  exercised  only within the term set
out in the  Notice  of  Grant,  and may be  exercised  during  such term only in
accordance with the terms of this Option Agreement.

     7.  TERMINATION  OF OPTION.  The Option shall  terminate on the  Expiration
Date; provided,  however,  that if the Company files any registration  statement
(other than a registration statement on Form S-4 or S-8) on or prior to May ___,
2003, the Expiration Date shall be a date that is (i) if the Shares are included
in  that  registration  statement,  90 days  after  the  effective  date of that
registration  statement,  or  (ii)  if the  Shares  are  not  included  in  that
registration  statement,  90 days after the effective  date of the  registration
statement in which the Shares are included in accordance  with the last sentence
of Section 4(a).

     8. DILUTION PROTECTION.

          (a) In the  event the  Company  shall (i)  declare a  dividend  on its
     Common Stock in shares of Common Stock or make a distribution  in shares of
     Common  Stock,  (ii)  declare a stock  split or reverse  stock split of its
     outstanding shares of Common Stock, (iii) combine its outstanding shares of
     Common Stock into a smaller number of shares of Common Stock, or (iv) issue
     by  reclassification  of  its  shares  of  Common  Stock  other  securities
     (including any such  reclassification in connection with a consolidation or
     merger in which the Company or any of its  subsidiaries  is the  continuing
     corporation),  then the  number of shares of Common  Stock of the  Company,
     deliverable  to the  Optionee  hereunder  and the  exercise  price  related
     thereto shall be adjusted so that the Optionee shall be entitled to receive
     the kind and  number of shares of  Common  Stock of the  Company  which the
     Optionee has the right to receive,  upon the happening of any of the events
     described above, with respect to the shares of the Company stock which were
     otherwise  deliverable pursuant herein. An adjustment made pursuant to this
     paragraph shall become  effective  immediately  after the effective date of
     such event;



                                       -5-

<PAGE>



          (b) Whenever the number of Shares or the exercise price of this Option
     is adjusted pursuant to this paragraph,  the Company shall promptly mail by
     first  class  mail,  postage  prepaid,  to the  Optionee,  notice  of  such
     adjustment or adjustments.

     9.  AVAILABILITY OF COMPANY STOCK.  The Company hereby agrees and covenants
that at all times  during the  Exercise  Period it shall  reserve for issuance a
sufficient  number  of shares of  common  stock as would be  required  upon full
exercise of the rights represented by this Agreement.

     10. NO RIGHT TO EMPLOYMENT.  Nothing in this  Agreement  shall be deemed to
create a relationship of employer to employee. The Company granted the Option to
Optionee in consideration of the performance of certain  consulting  services by
Optionee.

     11. TAX CONSEQUENCES. Some of the federal tax consequences relating to this
Option,  as of the date of this  Option,  are set forth  below.  THIS SUMMARY IS
NECESSARILY INCOMPLETE,  AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE  OPTIONEE  SHOULD  CONSULT A TAX ADVISER  BEFORE  EXERCISING  THIS OPTION OR
DISPOSING OF THE SHARES.

          (a)  Exercising  the Option.  The Optionee may incur  regular  federal
     income tax  liability  upon  exercise of the Option.  The Optionee  will be
     treated as having received  compensation income (taxable at ordinary income
     tax rates)  equal to the excess,  if any,  of the Fair Market  Value of the
     Exercised  Shares on the date of  exercise  over their  aggregate  Exercise
     Price.  If the  Optionee  is deemed for any reason to be an  employee,  the
     Company  will be  required  to  withhold  from his or her  compensation  or
     collect from the Optionee and pay to the applicable  taxing  authorities an
     amount equal to a  percentage  of this  compensation  income at the time of
     exercise.

          (b) Disposition of Shares. If the Optionee holds Shares for at least a
     year,  any gain  realized on  disposition  of the Shares will be treated as
     long-term capital gain for federal income tax purposes.

     12.  GOVERNING  LAW. This Agreement is governed by the laws of the State of
New York.

     IN WITNESS WHEREOF, this Agreement is executed this 3rd day of June, 1999.

     time, after the Date of Grant and prior to the Expiration Date.

     3. METHOD OF PAYMENT.  Payment of the aggregate  Exercise Price shall be by
any of the following, or a combination thereof, at the election of the Optionee:

          (a) Cash; or

          (b) Check.

     4. REGISTRATION UNDER THE SECURITIES ACT.

          (a)  "Piggyback  Registration".  If the  Company  shall  determine  to
     proceed with the actual preparation and filing of a registration  statement
     under the Securities Act in connection  with the proposed offer and sale of
     any of its  securities  by it or any of its security  holders in an initial
     public offering or otherwise  (other than a registration  statement on Form
     S-4 or S-8 or an offering  statement  on Form 1-A),  then the Company  will
     give  written  notice of its  determination  to all  record  holders of the
     Option and/or any Shares, as the case may be. Upon the written request from
     any  record  holder  or  holders  of an  aggregate  of more than 50% of the
     Options  and  Shares,  considered  in the  aggregate,  within 20 days after
     receipt of any such notice from the Company,  the Company  will,  except as
     herein provided,  cause all such Shares to be included in such registration
     statement,  all to the  extent  requisite  to  permit  the  sale  or  other
     disposition  by the  prospective  seller or  sellers of the Shares to be so
     registered;  provided,  further,  that  nothing  herein  shall  prevent the
     Company from, at any time, abandoning or delaying any registration.  If any
     registration  pursuant to this Section 4(a) shall be  underwritten in whole
     or in part,  the  Company  will  require  that  the  Shares  requested  for
     inclusion  pursuant to this Section 4(a) be included in the underwriting on
     the same  terms and  conditions  as the  securities  otherwise  being  sold
     through  the  underwriters.  In the event  that the  Shares  requested  for
     inclusion  pursuant to this  Section  4(a)  together  with any other shares
     which have similar piggyback registration rights (such other shares and the
     Shares being  collectively  referred to as the "Requested Stock") would, in
     the  sole  discretion  of the  managing  underwriter,  interfere  with  the
     successful  marketing of the shares of stock  offered by the  Company,  the
     number  of  shares of  Requested  Stock  otherwise  to be  included  in the
     underwritten  public offering may be reduced pro rata (by number of shares)
     among the holders thereof requesting such registration or excluded in their
     entirety  if so  required  by the  underwriter.  To the  extent  all or any
     portion of the  Requested  Stock is excluded from the  underwritten  public
     offering,  those shares of Requested Stock which are thus excluded from the
     underwritten  public  offering  shall be  withheld  from the  market by the
     holders  thereof for a period,  not to exceed 120 days,  which the managing
     underwriter  reasonably  determines  is  necessary  in order to effect  the
     underwritten public offering;  provided,  however, that the Shares included
     in  such   Requested   Stock  shall  be  included  in  the  Company's  next
     registration  statement,  subject to the earlier  registration  pursuant to
     Section 4(b).

          The obligation of the Company under this Section 4(a) shall be limited
     to one subsequent  registration  statement and shall not apply in the event
     and for so long as the  Company  has an  effective  registration  statement
     including a current prospectus pursuant to Section 4(b) hereof.

          (b)  Mandatory  Registration.  In the  event  the  undersigned  or its
     transferees  have not had  included in the  registration  statement  all of
     their Shares in connection with the Company's initial public offering, then
     the Company shall effect the  registration of all remaining  Shares as soon
     as  practicable,  but not later than 180 days after the  effective  date of
     such initial public offering;  provided,  however,  that such period may be
     extended or delayed by the Company for


                                       -2-

<PAGE>



     one  period  up to 90 days if,  upon  advice  of  counsel  at the time such
     registration  statement is required to filed, or at the time the Company is
     required to exercise best efforts to cause such  registration  statement to
     become effective,  such delay is advisable and in the best interests of the
     Company because of the existence of non-public material information,  or to
     allow the Company to complete any pending audit of its financial statement,
     or any  non-routine  transaction,  such  as a  merger,  reorganization,  or
     acquisition,  which would  require  the filing of a Current  Report on Form
     8-K.

          (c) Registration  Procedures.  If and whenever the Company is required
     by the  provisions  of Section 4(a) or 4(b) to effect the  registration  of
     Registrable Securities under the Securities Act, the Company will:

               i) prepare and file with the SEC a  registration  statement  with
          respect  to such  securities,  and use its best  efforts to cause such
          registration statement to become and remain effective until the Shares
          are freely salable without the volume limitations of Rule 144;

               ii)  prepare  and  file  with  the SEC  such  amendments  to such
          registration  statement and  supplements to the  prospectus  contained
          therein  as may be  necessary  to  keep  such  registration  statement
          effective  until the  Shares are freely  saleable  without  the volume
          limitations of Rule 144;

               iii)  furnish  to the  security  holders  participating  in  such
          registration   and  to  the   underwriters  of  the  securities  being
          registered  such  reasonable  number  of  copies  of the  registration
          statement,  preliminary  prospectus,  final  prospectus and such other
          documents  as such  underwriters  may  reasonably  request in order to
          facilitate the public offering of such securities;

               iv) use its best  efforts to register  or qualify the  securities
          covered by such registration  statement under such state securities or
          blue sky laws of such jurisdictions as such participating  holders may
          reasonably  request in writing  within 20 days  following the original
          filing of such registration  statement,  except that the Company shall
          not for any  purpose  be  required  to  execute a general  consent  to
          service  of  process  or  to  qualify  to  do  business  as a  foreign
          corporation in any jurisdiction wherein it is not so qualified;

               v)  notify   the   holders  of  Shares   participating   in  such
          registration,  promptly after it shall receive notice thereof,  of the
          time  when such  registration  statement  has  become  effective  or a
          supplement  to any  prospectus  forming  a part of  such  registration
          statement has been filed;

               vi) notify  such  holders  promptly of any request by the SEC for
          the  amending  or  supplementing  of such  registration  statement  or
          prospectus or for additional information;

               vii) prepare and file with the SEC,  promptly upon the request of
          any such holders,  any amendments or supplements to such  registration
          statement  or  prospectus  which,  in the  opinion of counsel for such
          holders  (and  concurred in by counsel for the  Company),  is required
          under the  Securities Act or the rules and  regulations  thereunder in
          connection with the distribution of Common Stock by such holder;

               viii) prepare and promptly file with the SEC and promptly  notify
          such  holders of the filing of such  amendment or  supplement  to such
          registration  statement or  prospectus  as may be necessary to correct
          any statements or omissions if, at the time when a prospectus relating
          to such  securities is required to be delivered  under the  Securities
          Act, any event shall have


                                       -3-

<PAGE>



          occurred  as the  result  of which  any such  prospectus  or any other
          prospectus  as then in effect would  include an untrue  statement of a
          material fact or omit to state any material fact necessary to make the
          statements  therein,  in the light of the  circumstances in which they
          were made, not misleading; and

               ix) advise such holders,  promptly  after it shall receive notice
          or obtain knowledge thereof,  of the issuance of any stop order by the
          SEC suspending the effectiveness of such registration statement or the
          initiation  or  threatening  of any  proceeding  for that  purpose and
          promptly  use its best  efforts to prevent  the  issuance  of any stop
          order or to obtain its withdrawal if such stop order should be issued.

          (d) Expenses.

               i) With respect to the registration  required pursuant to Section
          4(a) or 4(b) hereof, all fees, costs and expenses of and incidental to
          such  registration,  inclusion  and public  offering (as  specified in
          paragraph  (ii) below) in connection  therewith  shall be borne by the
          Company, provided, however, that any securityholders  participating in
          such registration  shall bear their pro rata share of the underwriting
          discount and commissions and transfer taxes.

               ii) The fees,  costs and expenses of  registration to be borne by
          the Company as provided in paragraph (i) above shall include,  without
          limitation,   all  registration,   filing,  and  NASD  fees,  printing
          expenses,  fees and  disbursements  of counsel and accountants for the
          Company,  and all legal fees and  disbursements  and other expenses of
          complying with state securities or blue sky laws of any  jurisdictions
          in  which  the  securities  to be  offered  are to be  registered  and
          qualified (except as provided in (i) above). Fees and disbursements of
          counsel and accountants for the selling  securityholders and any other
          expenses  incurred  by  the  selling   securityholders  not  expressly
          included above shall be borne by the selling securityholders.

          (e) Indemnification.

               i) The Company will  indemnify  and hold  harmless each holder of
          Shares which are included in a registration  statement pursuant to the
          provisions of Section 4(a) or 4(b) hereof, its directors and officers,
          and any underwriter (as defined in the Securities Act) for such holder
          and each person,  if any, who controls such holder or such underwriter
          within the meaning of the Securities  Act, from and against,  and will
          reimburse such holder and each such underwriter and controlling person
          with respect to, any and all loss, damage, liability, cost and expense
          to which such holder or any such underwriter or controlling person may
          become subject under the Securities Act or otherwise,  insofar as such
          losses,  damages,  liabilities,  costs or  expenses  are caused by any
          untrue  statement or alleged  untrue  statement  of any material  fact
          contained in such  registration  statement,  any prospectus  contained
          therein or any amendment or supplement thereto, or arise out of or are
          based  upon the  omission  or  alleged  omission  to state  therein  a
          material fact  required to be stated  therein or necessary to make the
          statements  therein,  in light of the circumstances in which they were
          made, not misleading;  provided, however, that the Company will not be
          liable  in any such case to the  extent  that any such  loss,  damage,
          liability,  cost or expenses  arises out of or is based upon an untrue
          statement or alleged untrue  statement or omission or alleged omission
          so made in conformity with information  furnished by such holder, such
          underwriter or such controlling person in writing specifically for use
          in the preparation thereof.

               ii) Each holder of Shares included in a registration  pursuant to
          the  provisions of Section 4(a) or 4(b) hereof will indemnify and hold
          harmless the Company, its directors and


                                       -4-

<PAGE>



          officers, any controlling person and any underwriter from and against,
          and will  reimburse  the Company,  its  directors  and  officers,  any
          controlling  person and any  underwriter  with respect to, any and all
          loss, damage,  liability,  cost or expense to which the Company or any
          controlling person and/or any underwriter may become subject under the
          Securities  Act  or  otherwise,   insofar  as  such  losses,  damages,
          liabilities,  costs or expenses are caused by any untrue  statement or
          alleged  untrue  statement  of any  material  fact  contained  in such
          registration  statement,  any  prospectus  contained  therein  or  any
          amendment or supplement thereto, or arise out of or are based upon the
          omission or alleged omission to state therein a material fact required
          to be stated therein or necessary to make the statements  therein,  in
          light of the circumstances in which they were made, not misleading, in
          each case to the  extent,  but only to the  extent,  that such  untrue
          statement or alleged untrue  statement or omission or alleged omission
          was so made in reliance  upon and in strict  conformity  with  written
          information  furnished by or on behalf of such holder specifically for
          use in the preparation thereof.

               iii) Promptly after receipt by an  indemnified  party pursuant to
          the provisions of paragraph (i) or (ii) of this Section 4(e) of notice
          of the  commencement of any action involving the subject matter of the
          foregoing indemnity provisions such indemnified party will, if a claim
          thereof is to be made against the  indemnifying  party pursuant to the
          provisions  of  said  paragraph  (i)  or  (ii),  promptly  notify  the
          indemnifying party of the commencement thereof; but the omission to so
          notify the  indemnifying  party will not relieve it from any liability
          which it may have to any  indemnified  party otherwise than hereunder.
          In case such action is brought  against any  indemnified  party and it
          notifies  the  indemnifying  party of the  commencement  thereof,  the
          indemnifying party shall have the right to participate in, and, to the
          extent that it may wish,  jointly  with any other  indemnifying  party
          similarly  notified,  to assume  the  defense  thereof,  with  counsel
          satisfactory to such  indemnified  party,  provided,  however,  if the
          defendants in any action  include both the  indemnified  party and the
          indemnifying  party and the  indemnified  party shall have  reasonably
          concluded  that  there may be legal  defenses  available  to it and/or
          other  indemnified  parties which are different from or in addition to
          those available to the indemnified party, or if there is a conflict of
          interest which would prevent counsel for the  indemnifying  party from
          also  representing  the indemnified  party,  the indemnified  party or
          parties have the right to select  separate  counsel to  participate in
          the  defense  of such  action on behalf of such  indemnified  party or
          parties.  After notice from the indemnifying party to such indemnified
          party  of  its  election  so  to  assume  the  defense  thereof,   the
          indemnifying  party  will  not be  liable  to such  indemnified  party
          pursuant to the provisions of said paragraph (i) or (ii) for any legal
          or other expense  subsequently  incurred by such indemnified  party in
          connection  with the defense  thereof other than  reasonable  costs of
          investigation,  unless (1) the  indemnified  party shall have employed
          counsel in accordance  with the provisions of the preceding  sentence,
          (2)  the   indemnifying   party  shall  not  have   employed   counsel
          satisfactory  to the  indemnified  party to represent the  indemnified
          party within a reasonable time after the notice of the commencement of
          the  action  or  (iii)  the  indemnifying  party  has  authorized  the
          employment of counsel for the indemnified  party at the expense of the
          indemnifying party.

     5.  TRANSFERABILITY  OF  OPTION.  This  Option may only be  transferred  in
compliance  with the Act.  The  Company may  request in its sole  discretion  an
opinion of counsel from the transferor  prior to any transfer to the effect that
the  Option  may be  transferred  by the  transferor  without  violation  of the
registration  provision of the Act.  Transferor  shall notify the Company of any
proposed  transfer.  The  terms  of this  Agreement  shall be  binding  upon the
executors, administrators, heirs, successors, and assigns of the Optionee.

out in the  Notice  of  Grant,  and may be  exercised  during  such term only in
accordance with the terms of this Option Agreement.

     7.  TERMINATION  OF OPTION.  The Option shall  terminate on the  Expiration
Date; provided,  however,  that if the Company files any registration  statement
(other than a registration statement on Form S-4 or S-8) on or prior to July 10,
2010, the Expiration Date shall be a date that is (i) if the Shares are included
in  that  registration  statement,  90 days  after  the  effective  date of that
registration  statement,  or  (ii)  if the  Shares  are  not  included  in  that
registration  statement,  90 days after the effective  date of the  registration
statement in which the Shares are included in accordance  with the last sentence
of Section 4(a) or with Section 4(b).

     8. DILUTION PROTECTION.

          (a) In the  event the  Company  shall (i)  declare a  dividend  on its
     Common Stock in shares of Common Stock or make a distribution  in shares of
     Common  Stock,  (ii)  declare a stock  split or reverse  stock split of its
     outstanding shares of Common Stock, (iii) combine its outstanding shares of
     Common Stock into a smaller number of shares of Common Stock, or (iv) issue
     by  reclassification  of  its  shares  of  Common  Stock  other  securities
     (including any such  reclassification in connection with a consolidation or
     merger in which the Company or any of its  subsidiaries  is the  continuing
     corporation),  then the  number of shares of Common  Stock of the  Company,
     deliverable  to the  Optionee  hereunder  and the  exercise  price  related
     thereto shall be adjusted so that the Optionee shall be entitled to receive
     the kind and  number of shares of  Common  Stock of the  Company  which the
     Optionee has the right to receive,  upon the happening of any of the events
     described above, with respect to the shares of the Company stock which were
     otherwise  deliverable pursuant herein. An adjustment made pursuant to this
     paragraph shall become  effective  immediately  after the effective date of
     such event;

          (b) Whenever the number of Shares or the exercise price of this Option
     is adjusted pursuant to this paragraph,  the Company shall promptly mail by
     first  class  mail,  postage  prepaid,  to the  Optionee,  notice  of  such
     adjustment or adjustments.

     9.  AVAILABILITY OF COMPANY STOCK.  The Company hereby agrees and covenants
that at all times  during the  Exercise  Period it shall  reserve for issuance a
sufficient  number  of shares of  common  stock as would be  required  upon full
exercise of the rights represented by this Agreement.

     10. NO RIGHT TO EMPLOYMENT.  Nothing in this  Agreement  shall be deemed to
create a relationship of employer to employee. The Company granted the Option to
Optionee in consideration of the performance of certain  consulting  services by
Optionee.

     11. TAX CONSEQUENCES. Some of the federal tax consequences relating to this
Option,  as of the date of this  Option,  are set forth  below.  THIS SUMMARY IS
NECESSARILY INCOMPLETE,  AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE  OPTIONEE  SHOULD  CONSULT A TAX ADVISER  BEFORE  EXERCISING  THIS OPTION OR
DISPOSING OF THE SHARES.

          (a)  Exercising  the Option.  The Optionee may incur  regular  federal
     income tax  liability  upon  exercise of the Option.  The Optionee  will be
     treated as having received  compensation income (taxable at ordinary income
     tax rates)  equal to the excess,  if any,  of the Fair Market  Value of the
     Exercised  Shares on the date of  exercise  over their  aggregate  Exercise
     Price.  If the  Optionee  is deemed for any reason to be an  employee,  the
     Company  will be



                                       -6-

<PAGE>


     required  to  withhold  from his or her  compensation  or collect  from the
     Optionee and pay to the applicable taxing  authorities an amount equal to a
     percentage of this compensation income at the time of exercise.

          (b) Disposition of Shares. If the Optionee holds Shares for at least a
     year,  any gain  realized on  disposition  of the Shares will be treated as
     long-term capital gain for federal income tax purposes.

     12.  GOVERNING  LAW. This Agreement is governed by the laws of the State of
New York.

     IN WITNESS WHEREOF, this Agreement is executed this ___ day of April, 1999.

     part,  subject  to the  terms of this  Agreement,  at any time from time to
     time, after the Date of Grant and prior to the Expiration Date.

          (b) Method of Exercise.  This Option is  exercisable by delivery of an
     exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
     which shall state the election to exercise the Option, the number of Shares

     3. METHOD OF PAYMENT.  Payment of the aggregate  Exercise Price shall be by
any of the following, or a combination thereof, at the election of the Optionee:

          (a) Cash; or

          (b) Check.

     4. REGISTRATION UNDER THE SECURITIES ACT.

          (a)  "Piggyback  Registration".  If the  Company  shall  determine  to
     proceed with the actual preparation and filing of a registration  statement
     under the Securities Act in connection  with the proposed offer and sale of
     any of its  securities  by it or any of its security  holders in an initial
     public offering or otherwise  (other than a registration  statement on Form
     S-4 or S-8 or an offering  statement  on Form 1-A),  then the Company  will
     give  written  notice of its  determination  to all  record  holders of the
     Option and/or any Shares, as the case may be. Upon the written request from
     any  record  holder  or  holders  of an  aggregate  of more than 50% of the
     Options  and  Shares,  considered  in the  aggregate,  within 20 days after
     receipt of any such notice from the Company,  the Company  will,  except as
     herein provided,  cause all such Shares to be included in such registration
     statement,  all to the  extent  requisite  to  permit  the  sale  or  other
     disposition  by the  prospective  seller or  sellers of the Shares to be so
     registered;  provided,  further,  that  nothing  herein  shall  prevent the
     Company from, at any time, abandoning or delaying any registration.  If any
     registration  pursuant to this Section 4(a) shall be  underwritten in whole
     or in part,  the  Company  will  require  that  the  Shares  requested  for
     inclusion  pursuant to this Section 4(a) be included in the underwriting on
     the same  terms and  conditions  as the  securities  otherwise  being  sold
     through  the  underwriters.  In the event  that the  Shares  requested  for
     inclusion  pursuant to this  Section  4(a)  together  with any other shares
     which have similar piggyback registration rights (such other shares and the
     Shares being  collectively  referred to as the "Requested Stock") would, in
     the  sole  discretion  of the  managing  underwriter,  interfere  with  the
     successful  marketing of the shares of stock  offered by the  Company,  the
     number  of  shares of  Requested  Stock  otherwise  to be  included  in the
     underwritten  public offering may be reduced pro rata (by number of shares)
     among the holders thereof requesting such registration or excluded in their
     entirety  if so  required  by the  underwriter.  To the  extent  all or any
     portion of the  Requested  Stock is excluded from the  underwritten  public
     offering,  those shares of Requested Stock which are thus excluded from the
     underwritten  public  offering  shall be  withheld  from the  market by the
     holders  thereof for a period,  not to exceed 120 days,  which the managing
     underwriter  reasonably  determines  is  necessary  in order to effect  the
     underwritten public offering;  provided,  however, that the Shares included
     in  such   Requested   Stock  shall  be  included  in  the  Company's  next
     registration  statement,  subject to the earlier  registration  pursuant to
     Section 4(b).

          The obligation of the Company under this Section 4(a) shall be limited
     to one subsequent  registration  statement and shall not apply in the event
     and for so long as the  Company  has an  effective  registration  statement
     including a current prospectus pursuant to Section 4(b) hereof.

          (b)  Mandatory  Registration.  In the  event  the  undersigned  or its
     transferees  have not had  included in the  registration  statement  all of
     their Shares in connection with the Company's initial public offering, then
     the Company shall effect the  registration of all remaining  Shares as soon
     as  practicable,  but not later than 180 days after the  effective  date of
     such initial public offering;  provided,  however,  that such period may be
     extended or delayed by the Company for


                                       -2-

<PAGE>



     one  period  up to 90 days if,  upon  advice  of  counsel  at the time such
     registration  statement is required to filed, or at the time the Company is
     required to exercise best efforts to cause such  registration  statement to
     become effective,  such delay is advisable and in the best interests of the
     Company because of the existence of non-public material information,  or to
     allow the Company to complete any pending audit of its financial statement,
     or any  non-routine  transaction,  such  as a  merger,  reorganization,  or
     acquisition,  which would  require  the filing of a Current  Report on Form
     8-K.

          (c) Registration  Procedures.  If and whenever the Company is required
     by the  provisions  of Section 4(a) or 4(b) to effect the  registration  of
     Registrable Securities under the Securities Act, the Company will:

               i) prepare and file with the SEC a  registration  statement  with
          respect  to such  securities,  and use its best  efforts to cause such
          registration statement to become and remain effective until the Shares
          are freely salable without the volume limitations of Rule 144;

               ii)  prepare  and  file  with  the SEC  such  amendments  to such
          registration  statement and  supplements to the  prospectus  contained
          therein  as may be  necessary  to  keep  such  registration  statement
          effective  until the  Shares are freely  saleable  without  the volume
          limitations of Rule 144;

               iii)  furnish  to the  security  holders  participating  in  such
          registration   and  to  the   underwriters  of  the  securities  being
          registered  such  reasonable  number  of  copies  of the  registration
          statement,  preliminary  prospectus,  final  prospectus and such other
          documents  as such  underwriters  may  reasonably  request in order to
          facilitate the public offering of such securities;

               iv) use its best  efforts to register  or qualify the  securities
          covered by such registration  statement under such state securities or
          blue sky laws of such jurisdictions as such participating  holders may
          reasonably  request in writing  within 20 days  following the original
          filing of such registration  statement,  except that the Company shall
          not for any  purpose  be  required  to  execute a general  consent  to
          service  of  process  or  to  qualify  to  do  business  as a  foreign
          corporation in any jurisdiction wherein it is not so qualified;

               v)  notify   the   holders  of  Shares   participating   in  such
          registration,  promptly after it shall receive notice thereof,  of the
          time  when such  registration  statement  has  become  effective  or a
          supplement  to any  prospectus  forming  a part of  such  registration
          statement has been filed;

               vi) notify  such  holders  promptly of any request by the SEC for
          the  amending  or  supplementing  of such  registration  statement  or
          prospectus or for additional information;

               vii) prepare and file with the SEC,  promptly upon the request of
          any such holders,  any amendments or supplements to such  registration
          statement  or  prospectus  which,  in the  opinion of counsel for such
          holders  (and  concurred in by counsel for the  Company),  is required
          under the  Securities Act or the rules and  regulations  thereunder in
          connection with the distribution of Common Stock by such holder;

               viii) prepare and promptly file with the SEC and promptly  notify
          such  holders of the filing of such  amendment or  supplement  to such
          registration  statement or  prospectus  as may be necessary to correct
          any statements or omissions if, at the time when a prospectus relating
          to such  securities is required to be delivered  under the  Securities
          Act, any event shall have


                                       -3-

<PAGE>



          occurred  as the  result  of which  any such  prospectus  or any other
          prospectus  as then in effect would  include an untrue  statement of a
          material fact or omit to state any material fact necessary to make the
          statements  therein,  in the light of the  circumstances in which they
          were made, not misleading; and

               ix) advise such holders,  promptly  after it shall receive notice
          or obtain knowledge thereof,  of the issuance of any stop order by the
          SEC suspending the effectiveness of such registration statement or the
          initiation  or  threatening  of any  proceeding  for that  purpose and
          promptly  use its best  efforts to prevent  the  issuance  of any stop
          order or to obtain its withdrawal if such stop order should be issued.

          (d) Expenses.

               i) With respect to the registration  required pursuant to Section
          4(a) or 4(b) hereof, all fees, costs and expenses of and incidental to
          such  registration,  inclusion  and public  offering (as  specified in
          paragraph  (ii) below) in connection  therewith  shall be borne by the
          Company, provided, however, that any securityholders  participating in
          such registration  shall bear their pro rata share of the underwriting
          discount and commissions and transfer taxes.

               ii) The fees,  costs and expenses of  registration to be borne by
          the Company as provided in paragraph (i) above shall include,  without
          limitation,   all  registration,   filing,  and  NASD  fees,  printing
          expenses,  fees and  disbursements  of counsel and accountants for the
          Company,  and all legal fees and  disbursements  and other expenses of
          complying with state securities or blue sky laws of any  jurisdictions
          in  which  the  securities  to be  offered  are to be  registered  and
          qualified (except as provided in (i) above). Fees and disbursements of
          counsel and accountants for the selling  securityholders and any other
          expenses  incurred  by  the  selling   securityholders  not  expressly
          included above shall be borne by the selling securityholders.

          (e) Indemnification.

               i) The Company will  indemnify  and hold  harmless each holder of
          Shares which are included in a registration  statement pursuant to the
          provisions of Section 4(a) or 4(b) hereof, its directors and officers,
          and any underwriter (as defined in the Securities Act) for such holder
          and each person,  if any, who controls such holder or such underwriter
          within the meaning of the Securities  Act, from and against,  and will
          reimburse such holder and each such underwriter and controlling person
          with respect to, any and all loss, damage, liability, cost and expense
          to which such holder or any such underwriter or controlling person may
          become subject under the Securities Act or otherwise,  insofar as such
          losses,  damages,  liabilities,  costs or  expenses  are caused by any
          untrue  statement or alleged  untrue  statement  of any material  fact
          contained in such  registration  statement,  any prospectus  contained
          therein or any amendment or supplement thereto, or arise out of or are
          based  upon the  omission  or  alleged  omission  to state  therein  a
          material fact  required to be stated  therein or necessary to make the
          statements  therein,  in light of the circumstances in which they were
          made, not misleading;  provided, however, that the Company will not be
          liable  in any such case to the  extent  that any such  loss,  damage,
          liability,  cost or expenses  arises out of or is based upon an untrue
          statement or alleged untrue  statement or omission or alleged omission
          so made in conformity with information  furnished by such holder, such
          underwriter or such controlling person in writing specifically for use
          in the preparation thereof.

               ii) Each holder of Shares included in a registration  pursuant to
          the  provisions of Section 4(a) or 4(b) hereof will indemnify and hold
          harmless the Company, its directors and

          and will  reimburse  the Company,  its  directors  and  officers,  any
          controlling  person and any  underwriter  with respect to, any and all
          loss, damage,  liability,  cost or expense to which the Company or any
          controlling person and/or any underwriter may become subject under the
          Securities  Act  or  otherwise,   insofar  as  such  losses,  damages,

          each case to the  extent,  but only to the  extent,  that such  untrue
          statement or alleged untrue  statement or omission or alleged omission
          was so made in reliance  upon and in strict  conformity  with  written
          information  furnished by or on behalf of such holder specifically for
          use in the preparation thereof.

               iii) Promptly after receipt by an  indemnified  party pursuant to
          the provisions of paragraph (i) or (ii) of this Section 4(e) of notice
          of the  commencement of any action involving the subject matter of the
          foregoing indemnity provisions such indemnified party will, if a claim
          thereof is to be made against the  indemnifying  party pursuant to the
          provisions  of  said  paragraph  (i)  or  (ii),  promptly  notify  the
          indemnifying party of the commencement thereof; but the omission to so
          notify the  indemnifying  party will not relieve it from any liability
          which it may have to any  indemnified  party otherwise than hereunder.
          In case such action is brought  against any  indemnified  party and it
          notifies  the  indemnifying  party of the  commencement  thereof,  the
          indemnifying party shall have the right to participate in, and, to the
          extent that it may wish,  jointly  with any other  indemnifying  party
          similarly  notified,  to assume  the  defense  thereof,  with  counsel
          satisfactory to such  indemnified  party,  provided,  however,  if the
          defendants in any action  include both the  indemnified  party and the
          indemnifying  party and the  indemnified  party shall have  reasonably
          concluded  that  there may be legal  defenses  available  to it and/or
          other  indemnified  parties which are different from or in addition to
          those available to the indemnified party, or if there is a conflict of
          interest which would prevent counsel for the  indemnifying  party from
          also  representing  the indemnified  party,  the indemnified  party or
          parties have the right to select  separate  counsel to  participate in
          the  defense  of such  action on behalf of such  indemnified  party or
          parties.  After notice from the indemnifying party to such indemnified
          party  of  its  election  so  to  assume  the  defense  thereof,   the
          indemnifying  party  will  not be  liable  to such  indemnified  party
          pursuant to the provisions of said paragraph (i) or (ii) for any legal
          or other expense  subsequently  incurred by such indemnified  party in
          connection  with the defense  thereof other than  reasonable  costs of
          investigation,  unless (1) the  indemnified  party shall have employed
          counsel in accordance  with the provisions of the preceding  sentence,
          (2)  the   indemnifying   party  shall  not  have   employed   counsel
          satisfactory  to the  indemnified  party to represent the  indemnified
          party within a reasonable time after the notice of the commencement of
          the  action  or  (iii)  the  indemnifying  party  has  authorized  the
          employment of counsel for the indemnified  party at the expense of the
          indemnifying party.

     5.  TRANSFERABILITY  OF  OPTION.  This  Option may only be  transferred  in
compliance  with the Act.  The  Company may  request in its sole  discretion  an
opinion of counsel from the transferor  prior to any transfer to the effect that
the  Option  may be  transferred  by the  transferor  without  violation  of the
registration  provision of the Act.  Transferor  shall notify the Company of any
proposed  transfer.  The  terms  of this  Agreement  shall be  binding  upon the
executors, administrators, heirs, successors, and assigns of the Optionee.

     6. TERM OF OPTION.  This Option may be  exercised  only within the term set
out in the  Notice  of  Grant,  and may be  exercised  during  such term only in
accordance with the terms of this Option Agreement.

     7.  TERMINATION  OF OPTION.  The Option shall  terminate on the  Expiration
Date; provided,  however,  that if the Company files any registration  statement
(other than a registration statement on Form S-4 or S-8) on or prior to July 10,
2010, the Expiration Date shall be a date that is (i) if the Shares are included
in  that  registration  statement,  90 days  after  the  effective  date of that
registration  statement,  or  (ii)  if the  Shares  are  not  included  in  that
registration  statement,  90 days after the effective  date of the  registration
statement in which the Shares are included in accordance  with the last sentence
of Section 4(a) or with Section 4(b).

     8. DILUTION PROTECTION.

          (a) In the  event the  Company  shall (i)  declare a  dividend  on its
     Common Stock in shares of Common Stock or make a distribution  in shares of
     Common  Stock,  (ii)  declare a stock  split or reverse  stock split of its
     outstanding shares of Common Stock, (iii) combine its outstanding shares of
     Common Stock into a smaller number of shares of Common Stock, or (iv) issue
     by  reclassification  of  its  shares  of  Common  Stock  other  securities
     (including any such  reclassification in connection with a consolidation or
     merger in which the Company or any of its  subsidiaries  is the  continuing
     corporation),  then the  number of shares of Common  Stock of the  Company,
     deliverable  to the  Optionee  hereunder  and the  exercise  price  related
     thereto shall be adjusted so that the Optionee shall be entitled to receive
     the kind and  number of shares of  Common  Stock of the  Company  which the
     Optionee has the right to receive,  upon the happening of any of the events
     described above, with respect to the shares of the Company stock which were
     otherwise  deliverable pursuant herein. An adjustment made pursuant to this
     paragraph shall become  effective  immediately  after the effective date of
     such event;

          (b) Whenever the number of Shares or the exercise price of this Option
     is adjusted pursuant to this paragraph,  the Company shall promptly mail by
     first  class  mail,  postage  prepaid,  to the  Optionee,  notice  of  such
     adjustment or adjustments.

     9.  AVAILABILITY OF COMPANY STOCK.  The Company hereby agrees and covenants
that at all times  during the  Exercise  Period it shall  reserve for issuance a
sufficient  number  of shares of  common  stock as would be  required  upon full
exercise of the rights represented by this Agreement.

     10. NO RIGHT TO EMPLOYMENT.  Nothing in this  Agreement  shall be deemed to
create a relationship of employer to employee. The Company granted the Option to
Optionee in consideration of the performance of certain  consulting  services by
Optionee.

     11. TAX CONSEQUENCES. Some of the federal tax consequences relating to this
Option,  as of the date of this  Option,  are set forth  below.  THIS SUMMARY IS
NECESSARILY INCOMPLETE,  AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE  OPTIONEE  SHOULD  CONSULT A TAX ADVISER  BEFORE  EXERCISING  THIS OPTION OR
DISPOSING OF THE SHARES.

          (a)  Exercising  the Option.  The Optionee may incur  regular  federal
     income tax  liability  upon  exercise of the Option.  The Optionee  will be
     treated as having received  compensation income (taxable at ordinary income
     tax rates)  equal to the excess,  if any,  of the Fair Market  Value of the
     Exercised  Shares on the date of  exercise  over their  aggregate  Exercise
     Price.  If the  Optionee  is deemed for any reason to be an  employee,  the
     Company will be


                                       -6-

<PAGE>



     required  to  withhold  from his or her  compensation  or collect  from the
     Optionee and pay to the applicable taxing  authorities an amount equal to a
     percentage of this compensation income at the time of exercise.

          (b) Disposition of Shares. If the Optionee holds Shares for at least a
     year,  any gain  realized on  disposition  of the Shares will be treated as
     long-term capital gain for federal income tax purposes.

     12.  GOVERNING  LAW. This Agreement is governed by the laws of the State of
New York.

     IN WITNESS WHEREOF, this Agreement is executed this day of April, 1999.
