                               PROSPECTUS SUMMARY

      The following summary highlights  selected  information  contained in this
prospectus.  This  summary  does not contain all of the  information  you should
consider  before  investing  in the  securities.  Before  making  an  investment
decision,  you should read the entire prospectus  carefully,  including the risk
factors  section,  the  financial  statements  and the  notes  to the  financial
statements.

THE COMPANY

      We develop, manufacture, market and license the rights to produce and sell
sensor systems that incorporate our patented  InvisaShield(TM)  presence-sensing
design and technology. Presence sensing is the reliable, repeatable detection of
people and conductive objects. With InvisaShield technology,  it is detection at
a close distance (typically less than one meter).

      InvisaShield technology is used today in our line of SmartGate(R) sensors:
life and property  safety  mechanisms for powered  closures,  including  parking
gates,  slide  gates,  swing  gates,  vertical  pivot  gates and the like.  In a
security  application,  first  generation  security  sensors using  InvisaShield
technology are in operation at a major museum in New England.

      To date,  our revenue has been derived  largely from the sale of SmartGate
sensors for powered  parking gates and slide gates.  Parking and slide gates are
motorized  barriers  used to control  parking  garage,  parking lot, and vehicle
traffic.  We anticipate that,  during the next two years,  revenues will reflect
the sale of additional  presence-sensing products designed to improve the safety
of various  products which may include  industrial  doors,  commercial  overhead
doors,  powered  slide and swing  gates,  vertical  pivot  gates,  and  products
designed to provide security sensing for various markets including museums.

      From inception  (February 12, 1997) through June 30, 2004, we were largely
focused on technology and product development. The estimated dollar amount spent
during this period on company-sponsored research and development was $3,087,468,
including $263,047 for the six months ended June 30, 2004, $558,277 for the year
ended  December 31, 2003 and $660,844 for the year ended  December 31, 2002.  We
continue to engage in significant product development activities. Because of our
losses (which  aggregated  $22,116,987  from  inception  through June 30, 2004),
limited capital,  and ongoing product  development  expenses,  footnote C of our
financial  statements  and the  accompanying  Report of  Independent  Registered
Public  Accounting  Firm discuss that  substantial  doubt exists  regarding  our
ability to continue as a going concern.

THE OFFERING

Outstanding Common Stock            19,473,332 shares1

Common Stock Offered                Up to  5,900,000  shares  of  common  stock,
                                    including   u p  to   4,400,000   shares  of
                                    common  stock  issuable  upon the conversion
                                    of  the  Series   A   Preferred  Stock   and
                                    1,500,000   shares  of common stock issuable
                                    upon the exercise of warrants  which have an
                                    exercise price of $1.00 per share.

Proceeds                            We will not  receive any  proceeds  from the
                                    sale of the  common  stock  that may be sold
                                    pursuant  to  this   prospectus.   We  will,
                                    however,  receive proceeds upon the exercise
                                    of  warrants  which,  if all  warrants  were
                                    exercised, would be $1,500,000.  None of the
                                    warrant   holders  have  any  obligation  to
                                    exercise their warrants.  Proceeds,  if any,
                                    received  from the exercise of warrants will
                                    be used for general corporate purposes.

                                  RISK FACTORS

      YOU SHOULD CAREFULLY CONSIDER THE RISKS AND UNCERTAINTIES  DESCRIBED BELOW
AND THE OTHER  INFORMATION IN THIS FILING BEFORE DECIDING TO PURCHASE OUR COMMON
STOCK. IF ANY OF THESE RISKS OR UNCERTAINTIES  OCCURS,  OUR BUSINESS,  FINANCIAL
CONDITION OR OPERATING  RESULTS  COULD BE  MATERIALLY  HARMED.  IN THAT CASE THE
TRADING  PRICE OF OUR COMMON STOCK COULD  DECLINE AND YOU COULD LOSE ALL OR PART
OF YOUR INVESTMENT. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY
ONES WE MAY FACE.

RISKS RELATED TO OUR BUSINESS

      WE HAVE  HISTORICALLY  INCURRED LOSSES AND LOSSES ARE EXPECTED TO CONTINUE
IN THE FUTURE, WHICH MEANS THAT WE MAY NOT BE ABLE TO CONTINUE OPERATIONS UNLESS
WE OBTAIN  ADDITIONAL  FUNDING.  OUR AUDITORS HAVE QUALIFIED THEIR AUDIT OPINION
WITH REGARD TO OUR ABILITY TO CONTINUE AS A GOING CONCERN.

      We have historically  incurred losses. In the twelve months ended December
31, 2003, we sustained net losses of $11.7 million.  From inception through June
30, 2004, we have sustained aggregate net losses of $22.1 million. Future losses
are expected to continue.  Accordingly,  we may experience significant liquidity
and cash flow problems if we are not able to raise additional  capital as needed
and on acceptable  terms.  No assurances can be given that we will be successful
in reaching or maintaining profitable operations.

      Because we increased  our product  development  activities,  we anticipate
that we will incur substantial  operating  expenses in connection with continued
research and  development,  testing and approval of our proposed  products,  and
expect  these  expenses  will result in  continuing  and,  perhaps,  significant
operating  losses until such time, if ever, that we are able to achieve adequate
product sales levels. Our ability to generate revenue and achieve  profitability
depends upon our ability,  alone or with others,  to complete the development of
our proposed products and manufacture, market and sell our products.

      Because  our  rate  of  expenses  is  high,  and due to our  very  limited
resources,  our auditors have included an  explanatory  paragraph in their audit
opinion with regard to our ability to continue as a going concern.

      WE WILL NEED TO RAISE ADDITIONAL  CAPITAL TO CONTINUE OUR OPERATIONS OR WE
MAY BE UNABLE TO FUND OUR  OPERATIONS,  PROMOTE  OUR  PRODUCTS  OR  DEVELOP  OUR
TECHNOLOGY.

      Our operations have relied almost  entirely on external  financing to fund
our operations.  Such financing has historically primarily come from the sale of
common stock to third parties and to a lesser degree from loans and revenue from
product  sales and license fees. We  anticipate,  based on our current  proposed
plans and  assumptions  relating to our operations  (including the timetable of,
and costs  associated with, new product  development),  that the proceeds of the
private  placement we completed  during 2004,  to date,  will be  sufficient  to
satisfy our  contemplated  cash  requirements at least through April of 2005. We
will need to raise additional capital to fund our anticipated operating expenses
and future expansion. Among other things, external financing will be required to
cover our  operating  costs.  We cannot assure you that  financing  whether from
external  sources or related parties will be available if needed or on favorable
terms.  If  additional  financing  is  not  available  when  required  or is not
available  on  acceptable  terms,  we may be unable to fund our  operations  and
planned growth,  develop or enhance our  technology,  take advantage of business
opportunities  or respond to competitive  market  pressures,  any of which could
make it more  difficult  for us to continue  operations.  Any  reduction  in our
operations may result in a lower stock price.


                                       4


      OUR ADDITIONAL FINANCING REQUIREMENTS COULD RESULT IN DILUTION TO EXISTING
STOCKHOLDERS.

      The additional  financings we will require may be obtained  through one or
more  transactions  which  effectively  dilute the  ownership  interests  of our
stockholders. Further, we may not be able to secure such additional financing on
terms  acceptable  to us, if at all. We have the  authority to issue  additional
shares of common  stock,  as well as  additional  classes or series of ownership
interests  or debt  obligations  which may be  convertible  into any one or more
classes or series of ownership interests.  We are authorized to issue 95,000,000
shares of common stock and 5,000,000 shares of preferred stock.  Such securities
may be issued without the approval or other consent of our stockholders.

      WE ARE A DEVELOPMENT  STAGE COMPANY AND HAVE A LIMITED  OPERATING  HISTORY
UPON WHICH YOU CAN BASE YOUR INVESTMENT DECISION.

      We have had a limited operating history and have had only limited revenue.
We are a development stage company, and accordingly,  we anticipate that we will
encounter  many  difficulties  and  risks  associated  with our  early  stage of
development  which  includes,  but is not  limited to, the  introduction  of new
products,  the  search  for and  hiring of new  personnel,  access  to  required
capital,  management  issues,  ramping  up  manufacturing  capacity,  and  other
important business aspects.

      WE WILL BE REQUIRED TO COMPETE WITH LARGER AND WELL-ESTABLISHED  COMPANIES
WHICH ARE BETTER FINANCED.

      There are a number of  well-established  companies which are well known in
the manufacture and/or distribution of products for the security and life-safety
markets.  Such companies  include  Honeywell,  Tyco,  General  Electric,  Bosch,
Siemens and others.  Accordingly,  we are subject to the difficult  challenge of
introducing  and  commercializing  our new  technology  and products in a market
place in a strong  competitive  environment.  Additionally,  our  technology and
products  based  thereon  will have to compete with other  technologies  such as
passive  infrared and various types of motion detection which are well known and
well accepted.

      WE ARE COMMERCIALIZING A NEW TECHNOLOGY WHICH WILL INVOLVE UNCERTAINTY AND
RISKS RELATED TO MARKET ACCEPTANCE.

      We are  commercializing a new technology with which we seek to gain market
acceptance and to demonstrate competitive advantages.  Our success is dependent,
to a large  degree,  upon our  ability to fully  develop and  commercialize  our
technology  and gain industry  acceptance  of our products,  based upon this new
technology and its perceived competitive advantages.  Accordingly, our prospects
must be considered in light of the risks,  expenses and difficulties  frequently
encountered in connection with the  establishment  of a new business in a highly
competitive industry,  characterized by frequent new product  introductions.  We
anticipate that we will incur substantial  operating expenses in connection with
the development  and testing of our proposed  products and expect these expenses
to result in continuing  and  significant  operating  losses until such time, if
ever, that we are able to achieve adequate levels of sales or license  revenues.
We  may  not  be  able  to  raise  additional   financing,   increase   revenues
significantly, or achieve profitable operations.


                                       5


      MANAGEMENT AND FOUNDERS OF THE COMPANY CONTROL A SIGNIFICANT AMOUNT OF OUR
COMMON STOCK AND SUCH CONCENTRATION OF OWNERSHIP MAY HAVE THE EFFECT OF DELAYING
OR PREVENTING A CHANGE OF CONTROL OF OUR COMPANY.

      As a result, these management stockholders will have significant influence
in matters requiring stockholder approval, including the election and removal of
directors,  the  approval of  significant  corporate  transactions,  such as any
merger, consolidation or sale of all or substantially all of the our assets, and
the control of our management and affairs.  Accordingly,  such  concentration of
ownership  may have the effect of delaying,  deferring or preventing a change in
our  control,  impeding  a merger,  consolidation,  takeover  or other  business
combination involving us or discouraging a potential acquirer from attempting to
obtain control of our company.

      THE  ABSENCE  OF  PRODUCT  LIABILITY  INSURANCE  COVERAGE  MAY  AFFECT OUR
BUSINESS.

      We may be exposed to  potential  product  liability  claims by  consumers.
Although we maintain product liability insurance, there can be no assurance that
such insurance will be sufficient to cover all possible  liabilities to which we
may be exposed.  Any product liability claim, even one that was not in excess of
our  insurance  coverage or one that is  meritless  and/or  unsuccessful,  could
adversely  affect our cash  available for other  purposes,  such as research and
development.  In  addition,  the  existence of a product  liability  claim could
affect the market price of our common stock.  In addition,  certain  vendors may
require minimum product liability insurance coverage as a condition precedent to
purchasing  or accepting  products for retail  distribution.  Product  liability
insurance coverage includes various deductibles, limitations and exclusions from
coverage,  and in any event might not fully cover any potential claims.  Failure
to satisfy  such  insurance  requirements  could impede the ability of us or our
distributors  or licensees to achieve broad retail  distribution of our proposed
products, which could have a material adverse effect on us.

      WE MAY  NOT BE ABLE  TO  EFFECTIVELY  PROTECT  OUR  INTELLECTUAL  PROPERTY
RIGHTS, THE FOUNDATION OF OUR BUSINESS,  WHICH COULD HARM OUR BUSINESS BY MAKING
IT EASIER FOR OUR COMPETITORS TO DUPLICATE OUR SERVICES.

      We  regard  certain  aspects  of our  products,  processes,  services  and
technology  as  proprietary.  We have taken steps to protect them with  patents,
copyrights,  trademarks,  restrictions on disclosure and other methods.  Despite
these precautions,  we cannot be certain that third parties will not infringe or
misappropriate   our   proprietary   rights  or  that  third  parties  will  not
independently   develop  similar   products,   services  and   technology.   Any
infringement,  misappropriation  or  independent  development  could cause us to
cease operations.


                                       6


      We have an issued  patent  and have  filed six  patent  applications  with
respect to various  aspects of our technology.  The pending patent  applications
may not be  issued  to us,  and if  issued,  may not  protect  our  intellectual
property from competition  which could seek to design around or invalidate these
patents.  Our  failure  to  adequately  protect  our  proprietary  rights in our
products,  services and  technology  could harm our business by making it easier
for our competitors to duplicate our services.

      We may have to resort to litigation to enforce our  intellectual  property
rights,  protect our trade  secrets,  determine  the  validity  and scope of the
proprietary  rights of others,  or defend ourselves from claims of infringement,
invalidity or unenforceability. Litigation may be expensive and divert resources
even if we win. This could adversely  affect our business,  financial  condition
and operating results such that it could cause us to reduce or cease operations.

      OTHER  PARTIES  MAY  ASSERT  THAT  OUR   TECHNOLOGY   INFRINGES  ON  THEIR
INTELLECTUAL  PROPERTY RIGHTS,  WHICH COULD DIVERT MANAGEMENT TIME AND RESOURCES
AND POSSIBLY FORCE OUR COMPANY TO REDESIGN OUR TECHNOLOGY.

      Technology-based  companies,  such  as  ours,  have  the  potential  to be
involved in litigation related to allegations of patent  infringement.  Although
we have no knowledge of any such claims,  from time to time,  third  parties may
assert patent,  copyright and other intellectual property rights to technologies
that are important to us. While there currently are no outstanding  infringement
claims  pending by or against us, we cannot  assure you that third  parties will
not assert  infringement claims against us in the future, that assertion by such
parties will not result in costly  litigation,  or that they will not prevail in
any such litigation.  In addition,  we cannot assure you that we will be able to
license  any valid and  infringed  patents  from third  parties on  commercially
reasonable  terms  or,  alternatively,   be  able  to  redesign  products  on  a
cost-effective  basis to avoid  infringement.  Any  infringement  claim or other
litigation against or by us could have a material adverse effect on us and could
cause us to reduce or cease operations.

      WE MAY NOT BE ABLE TO KEEP  UP WITH  RAPID  TECHNOLOGICAL  CHANGES,  WHICH
COULD RENDER OUR PRODUCTS LESS COMPETITIVE OR OBSOLETE.

      Changes in technology,  changes in customer  requirements and preferences,
introduction  of products and services  embodying new or different  technologies
and the  emergence  of new industry  standards  and  practices  could render our
existing  technology  and products  less  competitive  or  obsolete.  Our future
success  will depend on our  ability to enhance and improve the  responsiveness,
functionality,  accessibility  and features of our technology  and products.  We
expect that our marketplace will require  extensive  technological  upgrades and
enhancements  to  accommodate  many of the new  products  and  services  that we
anticipate will be added to our  marketplace.  We cannot assure you that we will
be able to expand and  upgrade  our  technology  and  systems,  or  successfully
integrate new  technologies or systems we develop in the future,  to accommodate
such increases in a timely manner.


                                       7


      WE MAY NOT EFFECTIVELY MANAGE THE GROWTH NECESSARY TO EXECUTE OUR BUSINESS
PLAN, WHICH COULD ADVERSELY AFFECT THE QUALITY OF OUR OPERATIONS AND OUR COSTS.

      In order to successfully  execute our business plan, we must significantly
increase the number of strategic partners,  manufactures,  dealers, distributors
and customers that use our products.  This growth will place significant  strain
on our personnel, systems and resources. We also expect that we will continue to
hire employees, including technical, management-level employees, and sales staff
for the foreseeable  future.  This growth will require us to improve management,
technical,  information and accounting systems,  controls and procedures. We may
not be able to  maintain  the  quality  of our  operations,  control  our costs,
continue  complying  with all  applicable  regulations  and expand our  internal
management, technical information and accounting systems in order to support our
desired  growth.  We cannot be sure that we will manage our growth  effectively,
and our failure to do so could cause us to reduce or cease operations.

      WE ARE DEPENDENT ON EXISTING MANAGEMENT

      Our success is substantially dependent on the efforts and abilities of our
President and Chief Executive Officer,  Herbert M. Lustig.  Decisions concerning
our business and our  management are and will continue to be made by Mr. Lustig.
The loss or  interruption  of his  continued  services  would have a  materially
adverse  effect on our business  operations and  prospects.  Further,  we do not
maintain key-man life insurance.

      Our future  success also will depend in part on the  continued  service of
our key  management  personnel  and our  ability  to  identify,  hire and retain
additional personnel, including marketing and sales staff. We experience intense
competition  for  qualified  personnel,  and the  existence  of  non-competition
agreements between prospective  employees and their former employers may prevent
us from  hiring  those  individuals  or  subject  us to suit from  their  former
employers.

      While we attempt to provide competitive  compensation  packages to attract
and retain key  personnel,  some of our  competitors  are likely to have greater
resources  and more  experience  than we have,  making  it  difficult  for us to
compete successfully for key personnel.

RISKS RELATED TO OUR SECURITIES

      THE LIMITED  PRIOR  PUBLIC  MARKET AND TRADING  MARKET MAY CAUSE  POSSIBLE
VOLATILITY IN OUR STOCK PRICE.

      There has only been a limited  public market for our  securities and there
can be no assurance  that an active  trading  market in our  securities  will be
maintained. The OTCBB is an unorganized,  inter-dealer,  over-the-counter market
which  provides  significantly  less  liquidity  than  NASDAQ  and the  national
securities  exchange,  and  quotes  for  securities  quoted on the OTCBB are not
listed in the  financial  sections of newspapers as are those for NASDAQ and the
national securities exchange. In addition,  the overall market for securities in
recent years has  experienced  extreme price and volume  fluctuations  that have
particularly  affected the market prices of many smaller companies.  The trading
price of our common stock is expected to be subject to significant  fluctuations
in response to variations in quarterly  operating results,  changes in analysts'
earnings  estimates,  announcements  of  innovations  by us or our  competitors,
general conditions in the industry in which we operate and other factors.  These
fluctuations,  as well as general  economic  and market  conditions,  may have a
material or adverse effect on the market price of our common stock.


                                       8


      LIMITATIONS  IN  CONNECTION  WITH THE  AVAILABILITY  OF  QUOTES  AND ORDER
INFORMATION ON THE OTCBB

      Trades and quotations on the OTCBB involve a manual process and the market
information  for such  securities  cannot  be  guaranteed.  In  addition,  quote
information,  or even firm quotes,  may not be available.  The manual  execution
process may delay order processing and intervening price fluctuations may result
in the failure of a limit order to execute or the execution of a market order at
a significantly  different price.  Execution of trades,  execution reporting and
the  delivery  of  legal  trade  confirmation  may  be  delayed   significantly.
Consequently, one may not able to sell shares of our common stock at the optimum
trading prices.

      DELAYS IN ORDER COMMUNICATION IN THE OTCBB

      Electronic  processing of orders is not available for securities traded on
the OTCBB and high order volume and communication risks may prevent or delay the
execution of one's OTCBB trading orders. This lack of automated order processing
may affect the timeliness of order execution  reporting and the  availability of
firm quotes for shares of our common  stock.  Heavy market  volume may lead to a
delay in the processing of OTCBB security orders for shares of our common stock,
due to the manual nature of the market.  Consequently,  one may not able to sell
shares of our common stock at the optimum trading prices.

      PENNY STOCK  REGULATIONS MAY IMPOSE CERTAIN  RESTRICTIONS ON MARKETABILITY
OF OUR SECURITIES.

      Our common stock is deemed to be "penny  stock" as that term is defined in
Rule 3a51-1  promulgated under the Securities  Exchange Act of 1934.  Subject to
certain exceptions, penny stocks are stock:

      o     With a price of less than  $5.00 per share or an  exercise  price of
            less than $5.00 per share;

      o     That are not traded on a "recognized" national exchange;

      o     Whose  prices  are not  quoted  on the  NASDAQ  automated  quotation
            system; or

      o     In issuers with net  tangible  assets less than $2.0 million (if the
            issuer has been in continuous operation for at least three years) or
            $5.0 million (if in continuous operation for less than three years),
            or with  average  revenues  of less than $6.0  million  for the last
            three years.

      As a result,  our common stock is subject to rules that impose  additional
sales  practice  requirements  on  broker-dealers  who sell such  securities  to
persons other than  established  customers and accredited  investors  (generally
those with assets in excess of $1,000,000 or annual income  exceeding  $200,000,
or $300,000 together with their spouse). For transactions covered by such rules,
the broker-dealer must make a special suitability determination for the purchase
of such  securities  and have received the  purchaser's  written  consent to the
transaction prior to the purchase. Additionally, for any transaction involving a
penny  stock,  unless  exempt,  the rules  require  the  delivery,  prior to the


                                       9


transaction,  of a risk disclosure  document mandated by the Commission relating
to the penny stock market.  The broker dealer must also disclose the  commission
payable to both the broker  dealer and the  registered  representative,  current
quotations  for the  securities  and,  if the broker  dealer is the sole  market
maker,  the  broker  dealer  must  disclose  this fact and the  broker  dealer's
presumed  control  over the market.  Finally,  monthly  statements  must be sent
disclosing  recent price information for the penny stock held in the account and
information on the limited market in penny stocks.  In addition,  the Commission
currently intends to create additional  obligations with respect to the transfer
of penny stocks.  Most importantly,  the Commission proposes that broker-dealers
must wait two business days after  providing  buyers with  disclosure  materials
regarding  a  security   before   effecting  a  transaction  in  such  security.
Consequently, the "penny stock" rules may restrict the ability of broker dealers
to sell our  securities  and may affect the  ability  of  investors  to sell our
securities in the secondary  market and the price at which such  purchasers  can
sell any such securities,  thereby affecting the liquidity of the market for our
common stock.

      Stockholders should be aware that, according to the Commission, the market
for penny stocks has suffered in recent years from  patterns of fraud and abuse.
Such patterns include:

o     control of the market for the security by one or more  broker-dealers that
      are often related to the promoter or issuer;

o     manipulation of prices through prearranged matching of purchases and sales
      and false and misleading press releases;

o     "boiler  room"  practices   involving  high  pressure  sales  tactics  and
      unrealistic price projections by inexperienced sales persons;

o     excessive and  undisclosed  bid-ask  differentials  and markups by selling
      broker-dealers; and

o     the   wholesale   dumping  of  the  same   securities   by  promoters  and
      broker-dealers  after  prices have been  manipulated  to a desired  level,
      along  with the  inevitable  collapse  of  those  prices  with  consequent
      investor losses.

Our  management  is aware of the abuses that have occurred  historically  in the
penny stock market.

      RISK OF MARKET FRAUD

      OTCBB securities are frequent targets of fraud or market manipulation. Not
only because of their generally low price,  but also because the OTCBB reporting
requirements  for these  securities are less stringent than for listed or NASDAQ
traded  securities,  and no  exchange  requirements  are  imposed.  Dealers  may
dominate  the market and set prices  that are not based on  competitive  forces.
Individuals  or groups may create  fraudulent  markets  and  control the sudden,
sharp increase of price and trading  volume and the equally  sudden  collapse of
the market price for shares of our common stock.


                                       10


      LIMITED LIQUIDITY ON THE OTCBB

      When fewer shares of a security are being traded on the OTCBB,  volatility
of prices may  increase  and price  movement  may outpace the ability to deliver
accurate quote information. Due to lower trading volumes in shares of our common
stock,  there may be a lower likelihood of one's orders for shares of our common
stock being executed, and current prices may differ significantly from the price
one was quoted by the OTCBB at the time of one's order entry.

      LIMITATION IN  CONNECTION  WITH THE EDITING AND CANCELING OF ORDERS ON THE
OTCBB

      Orders for OTCBB  securities  may be  canceled  or edited  like orders for
other  securities.  All  requests to change or cancel an order must be submitted
to,  received  and  processed by the OTCBB.  Due to the manual order  processing
involved in  handling  OTCBB  trades,  order  processing  and  reporting  may be
delayed,  and one may not be able to cancel or edit one's  order.  Consequently,
one may not able to sell  shares  of our  common  stock at the  optimum  trading
prices.

      INCREASED DEALER COMPENSATION

      The dealer's spread (the difference between the bid and ask prices) may be
large and may result in substantial losses to the seller of shares of our common
stock on the OTCBB if the stock must be sold immediately. Further, purchasers of
shares of our common stock may incur an immediate  "paper" loss due to the price
spread.  Moreover,  dealers  trading  on the  OTCBB may not have a bid price for
shares of our common stock on the OTCBB. Due to the foregoing, demand for shares
of our common stock on the OTCBB may be decreased or eliminated.

      ADDITIONAL  AUTHORIZED  SHARES OF OUR  COMMON  STOCK AND  PREFERRED  STOCK
AVAILABLE FOR ISSUANCE MAY ADVERSELY AFFECT THE MARKET.

      We are authorized to issue  95,000,000  shares of our common stock.  As of
August  31,  2004,  there  were  19,473,332  shares of common  stock  issued and
outstanding.  However, the total number of shares of our common stock issued and
outstanding  does not include shares reserved in anticipation of the exercise of
options or warrants. As of August 31, 2004, we had outstanding stock options and
warrants to purchase  approximately  7,926,514  shares of our common stock,  the
exercise price of which range between $1.00 per share to $7.25 per share, and we
have  reserved  shares of our common stock for issuance in  connection  with the
potential  exercise  thereof.  To  the  extent  such  options  or  warrants  are
exercised,  the holders of our common stock will experience further dilution. In
addition,  in the event that any future  financing  should be in the form of, be
convertible into or exchangeable for, equity  securities,  and upon the exercise
of options and warrants, investors may experience additional dilution.


                                       11


      The exercise of the  outstanding  derivative  securities,  will reduce the
percentage of common stock held by our stockholders. Further, the terms on which
we could obtain additional capital during the life of the derivative  securities
may be  adversely  affected,  and it should be expected  that the holders of the
derivative  securities  would  exercise  them at a time when we would be able to
obtain equity  capital on terms more  favorable  than those provided for by such
derivative securities.  As a result, any issuance of additional shares of common
stock may cause our current  stockholders to suffer  significant  dilution which
may adversely affect the market.

      In addition to the above  referenced  shares of common  stock which may be
issued without  stockholder  approval,  we have  5,000,000  shares of authorized
preferred stock, the terms of which may be fixed by our Board. We presently have
22,000  issued and  outstanding  shares of preferred  stock and while we have no
present plans to issue any additional  shares of preferred  stock, our Board has
the authority,  without  stockholder  approval,  to create and issue one or more
additional series of such preferred stock and to determine the voting,  dividend
and other rights of holders of such preferred stock. The issuance of any of such
series of  preferred  stock may have an adverse  effect on the holders of common
stock.

      SHARES ELIGIBLE FOR FUTURE SALE MAY ADVERSELY AFFECT THE MARKET.

      From time to time, certain of our stockholders may be eligible to sell all
or some of  their  shares  of  common  stock  by  means  of  ordinary  brokerage
transactions  in the open  market  pursuant to Rule 144,  promulgated  under the
Securities Act,  subject to certain  limitations.  In general,  pursuant to Rule
144,  a  stockholder  (or  stockholders  whose  shares are  aggregated)  who has
satisfied a one year  holding  period may,  under  certain  circumstances,  sell
within any three month period a number of  securities  which does not exceed the
greater  of 1% of the then  outstanding  shares of common  stock or the  average
weekly  trading volume of the class during the four calendar weeks prior to such
sale.  Rule  144  also  permits,  under  certain  circumstances,   the  sale  of
securities,  without any limitation, by our stockholders that are non-affiliates
that have  satisfied a two year  holding  period.  Any  substantial  sale of our
common stock pursuant to Rule 144 or pursuant to any resale  prospectus may have
material adverse effect on the market price of our securities.

ADDITIONAL RISKS

      LIMITATION ON DIRECTOR/OFFICER LIABILITY.

      As  permitted  by Nevada  law,  our  articles of  incorporation  limit the
liability  of our  directors  for  monetary  damages for breach of a  director's
fiduciary  duty except for  liability in certain  instances.  As a result of our
charter  provision  and Nevada  law,  stockholders  may have  limited  rights to
recover against directors for breach of fiduciary duty. In addition,  our bylaws
provide that we shall indemnify our directors, officers, employees and agents if
such persons acted in good faith and reasoned that their conduct was in our best
interest.


                                       12


      WE HAVE NO HISTORY OF PAYING DIVIDENDS ON OUR COMMON STOCK.

      We have  never  paid any cash  dividends  on our  common  stock and do not
anticipate  paying any cash  dividends  on our common  stock in the  foreseeable
future. We plan to retain any future earnings to finance growth. If we decide to
pay dividends to the holders of our common stock, such dividends may not be paid
on a timely basis.

      PROVISIONS OF OUR ARTICLES OF  INCORPORATION  AND NEVADA LAW COULD DEFER A
CHANGE OF OUR MANAGEMENT WHICH COULD DISCOURAGE OR DELAY OFFERS TO ACQUIRE US.

      Provisions  of our  articles of  incorporation  and Nevada law may make it
more difficult for someone to acquire  control of us or for our  stockholders to
remove existing management,  and might discourage a third party from offering to
acquire us, even if a change in control or in management  would be beneficial to
our stockholders.  For example,  our articles of incorporation allow us to issue
shares  of  preferred   stock  without  any  vote  or  further   action  by  our
stockholders.  Our Board has the  authority  to fix and  determine  the relative
rights and preferences of preferred  stock.  Our Board also has the authority to
issue  preferred  stock without further  stockholder  approval,  including large
blocks of preferred  stock. As a result,  our Board could authorize the issuance
of a series of preferred  stock that would grant to holders the preferred  right
to our assets upon  liquidation,  the right to receive dividend  payments before
dividends  are  distributed  to the holders of common stock and the right to the
redemption of the shares,  together with a premium,  prior to the  redemption of
our common stock.

                                  OUR BUSINESS

      We develop, manufacture, market and license the rights to produce and sell
sensor systems that incorporate our patented  InvisaShield(TM)  presence-sensing
design and technology. Presence sensing is the reliable, repeatable detection of
people and conductive  objects.  With  InvisaShield,  it is detection at a close
distance (typically less than one meter).

      InvisaShield technology is used today in our line of SmartGate(R) sensors:
life and property  safety  mechanisms for powered  closures,  including  parking
gates,  slide  gates,  swing  gates,  vertical  pivot  gates and the like.  In a
security  application,  first  generation  security  sensors using  InvisaShield
technology are in operation at a major museum in New England.

      To date, our revenue has been  derived  largely from the sale of SmartGate
sensors for powered  parking gates and slide gates.  Parking and slide gates are
motorized  barriers  used to control  parking  garage,  parking lot, and vehicle
traffic.  We anticipate that,  during the next two years,  revenues will reflect
the sale of additional  presence-sensing products designed to improve the safety
of various  products which may include  industrial  doors,  commercial  overhead
doors,  powered  slide and swing  gates,  vertical  pivot  gates,  and  products
designed to provide security sensing for various markets including museums.

      From inception  (February 12, 1997) through June 30, 2004, we were largely
focused on technology and product development. The estimated dollar amount spent
during this period on company-sponsored research and development was $3,087,468,
including  $558,277  for the year ended  December  31, 2003 and $660,844 for the
year ended  December  31,  2002.  We continue to engage in  significant  product
development activities.  Because of our losses (which aggregate $22,116,987 from
inception  through  June  30,  2004),   limited  capital,  and  ongoing  product
development   expenses,   footnote  C  of  our  financial   statements  and  the
accompanying  Report of Independent  Registered  Public  Accounting Firm discuss
that  substantial  doubt exists regarding the our ability to continue as a going
concern.


                                       13


HISTORY

      We are a  development  stage  company  that  is  commercializing  patented
presence-sensing   technology  under  the  trade  name  InvisaShield.   We  were
incorporated  in  Nevada  on  July 9,  1998 to  provide  computer  analysis  and
solutions in  anticipation  of potential  date-related  computer system failures
associated with the year 2000. Our original  business plan was abandoned  before
significant  commercialization  and on February 9, 2000, we acquired  SmartGate,
L.C., in consideration  for the issuance of 7,743,558 shares of our common stock
representing  approximately  74% of our  capital  stock then  outstanding.  As a
result, SmartGate,  L.C., became our wholly owned subsidiary,  which markets our
InvisaShield safety products under the brand name SmartGate.  SmartGate, L.C. is
a  development   stage  company   organized  in  January  1997  to  develop  and
commercialize,  pursuant to a license, patented presence-sensing  technology for
safety applications in the powered closure market.

      From  an  accounting  perspective,  SmartGate,  L.C.  was  considered  the
acquirer  in this  transaction  and,  as a result,  the  accompanying  Financial
Statements reflect the operations of SmartGate, L.C. from inception. On February
26, 2002, we acquired Radio Metrix Inc. from affiliated parties.

      Radio Metrix Inc. is a wholly owned  subsidiary  which is  commercializing
our InvisaShield  security  products.  Radio Metrix Inc. is a development  stage
company which was  incorporated in Florida on March 19, 1992.  Radio Metrix Inc.
owns the patent and  patent  applications  to the  InvisaShield  technology  and
controlled the InvisaShield technology. As a result of this acquisition, we have
sole  rights  to  commercialize  the  InvisaShield  technology  in  all  markets
worldwide and we own the issued patent and pending  patent  applications  to the
InvisaShield technology.

PRODUCTS

      Our current and planned products are divided into two market categories as
follows:

      Safety Market Category - Many safety devices and safety  functions  depend
upon   presence-sensing   technology.   We   continue  to  develop  a  range  of
presence-sensing products for the safety market under our brand name SmartGate.

      We believe  that our  safety  products  offer  potential  operational  and
maintenance  benefits to the powered  closure  industry.  Today we offer  safety
products for powered parking barrier gates, and slide gates.

      We also have developed prototypes of presence-sensing  products for use in
powered commercial  overhead doors,  powered industrial doors (which are used in
commercial,  manufacturing,  and industrial  buildings) and  residential  garage
doors. We believe that there may be other applications for our  presence-sensing
technology in the safety market.  Ultimately,  we plan to offer safety  products
based upon our InvisaShield  technology to be incorporated  into a broad base of
powered closure devices produced by other companies.


                                       14


      To date,  substantially  all of our revenue  (which has been  limited) has
been derived from the sale of our  SmartGate  presence-sensing  products.  These
products are designed to be  incorporated  into powered  parking  barrier gates.
Powered  parking  barrier  gates  are  commonly  used for  traffic  control  and
generally have a power operated barrier arm typically made of metal, wood or PVC
which moves vertically between an open and a closed position. Our product places
invisible presence sensing in front of and moving with the potentially dangerous
barrier arm to identify the presence of people and  vehicles.  When an object is
identified  in the path of the moving  barrier  arm,  our  product  signals  the
powered operator system, which is manufactured by nonaffiliated entities for its
predetermined  response, such as stopping and reversing the barrier arm. See the
financial statements for revenues from this product category.

      During each of the last three fiscal  years,  more than 90% of our revenue
was attributable to customers  domiciled in the United States. For sales made to
non-U.S.  domiciled  customers,  the  country  to  which  the  most  sales  were
attributed was the United Kingdom.

      In July  2002,  we signed  an  agreement,  making  Rytec  Corporation  our
exclusive licensee to use our InvisaShield technology as original equipment used
with high-speed  industrial doors in the North American market.  We believe that
Rytec Corporation is the largest manufacturer of high-speed  industrial doors in
North America.  These doors are frequently used in manufacturing  and industrial
environments  where  air-conditioned,  cooler,  and freezer  areas are separated
within warehouses or other buildings.  We are completing internal testing of our
product for use with  Rytec's high speed  industrial  doors and hope to commence
customer testing ("beta testing") by November of 2005.

      As further  described below, we believe that the  InvisaShield  technology
can  perform  non-contact  presence-sensing  tasks  that  may not  currently  be
possible with competing technologies.

      Security  Market  Category  -  Security  systems  and  security  equipment
generally rely, to varying degrees, on presence-sensing technologies to identify
the presence of potential intruders and trespassers,  or to provide surveillance
of valuable objects.

      Our planned security products are being developed as components  available
to security professionals.  These products would provide additional features and
functions for new and/or existing security systems.  They will compete with and,
in some applications, complement existing presence-sensing technologies that are
used in the security  market today - such as infrared  and/or  microwave  motion
detectors, lasers, light beam systems and magnetic contacts or switches.

      We have  demonstrated  prototypes of  InvisaShield  security  products for
museum, retail, industrial,  commercial,  defense and governmental applications.
These  security  products  can place an invisible  presence-sensing  filed (in a
fashion similar to our safety sensing shield) around exposed  perimeters,  doors
exposed  perimeters,  doors and  windows - or around  valuable  objects  such as
safes, locking cabinets, display cases, objects of art, and jewelry.


                                       15


      In September  2004,  Invisa's  management will present a case study at the
14th  Annual  International  Association  of  Museum  Facilities  Administrators
(IAMFA)  Conference that illustrates the use of InvisaShield  capacitive sensors
for protecting and securing valuable exhibits.  We will describe and demonstrate
how  InvisaShield  technology  has  been  used  to  solve  a  specific  security
challenge,  namely, that of providing open access to exhibits - while protecting
them from vandalism or inadvertent damage.

MARKETING

      We will continue to focus our marketing  efforts in the development of OEM
(Original  Equipment  Manufacturer)  licensing  of our  technology  as  well  as
building  and  supporting  the  distribution  channel and dealer  network of our
SmartGate systems.  We periodically  participate in various trade conferences in
the  security  market and safety  market  where we  demonstrate  our current and
planned products and technology to potential customers.

      We have historically concentrated marketing efforts on potential customers
whom we believe to be market leaders or otherwise  high profile within  specific
markets.  Currently, we target the market for safety products applied to powered
parking gates, industrial doors, commercial overhead doors, powered slide gates,
swing gates and vertical pivot gates.

      We sell our safety products to OEMs and through  dealers and  distributors
and in some  instances  directly to targeted  customers.  In 2004, we anticipate
potential  sales to  manufacturers  for use of the  InvisaShield  technology  as
original equipment in various applications for powered closure products.

      The U.S. arm of ASCOM Transport  Revenue Systems is our largest  customer.
We are not dependent  upon any single  customer,  dealer,  or distributor in the
safety market, or otherwise.

      We are currently  evaluating channels of distribution for planned security
products.  Distribution would include sales to and through dealers, distributors
and  manufacturers.  While products in this market category have not contributed
to our revenue in the past,  we believe that our planned  security  products may
ultimately  represent  a material  portion of our  business.  We plan to further
investigate the potential for  InvisaShield-based  security  products in markets
that include museums, retail, residential, governmental, and defense, as well as
other sectors.

THE TECHNOLOGY

      The  InvisaShield   technology  uses  electronic   circuitry  that  emits,
controls,  and senses changes in an invisible  energy field. The field is based,
in part, upon low energy radio waves oscillating  within a controlled  frequency
range.   The  field   monitored   ranges   from  a  distance  of  one  meter  to
touch-sensitive,  based upon the selected  application and circuitry  constantly
checks  the  field  to test  for the  presence  of  people,  vehicles  or  other
conductive  objects  (objects that conduct  electricity)  that would disturb the
monitored field.


                                       16


      We believe that the InvisaShield technology is a novel and proprietary way
to provide  presence  sensing.  At the core of the  technology is the ability to
project a field or zone capable of detecting most conductive  objects that enter
the field. The field is projected from a metallic  substance,  referred to as an
antenna,  which  may  consist  of  wire,  self-adhesive  metallic  tape or other
metallic items. The technology permits flexibility in designing and locating the
antenna. This may provide unique opportunities to place presence-sensing  fields
where they can be used more  efficiently  or  effectively.  We believe that this
flexibility   enables  the  InvisaShield   technology  to  perform   non-contact
presence-sensing  tasks  that  may not  currently  be  possible  with  competing
technologies and to perform presence-sensing tasks similar to those performed by
competing technologies in a potentially more efficient,  effective, and reliable
manner.

      We believe that the  InvisaShield  technology  has a number of operational
advantages.  The  technology  does not depend upon lenses,  beams or  reflectors
which may require replacement,  cleaning and aligning.  We also believe that the
non-intrusive,  non-contact  presence-sensing  capability  of our  technology is
generally  not  disrupted by its  operating  environment,  including  electronic
noise, mechanical noise, temperature,  dust, frost, snow, ice or other operating
conditions.   We   believe   that   InvisaShield   technology   may   be  a  new
presence-sensing  technology  that gives  greater  capability,  flexibility  and
benefits than non-contact sensing.

      The  Company  recently  has  completed  the  design and  development  of a
cost-reduced,  4th generation digital version of its SmartGate safety system for
powered closures (SmartGate III).

      Competing   Technologies  -  The   presence-sensing   business  is  highly
competitive,  consisting of numerous manufacturers of presence-sensing  products
based on various technologies,  including infrared, ultrasonic, laser, microwave
and similar technologies. For the most part, these technologies have been in use
for a number of years and, in many cases, may not be proprietary.

      Our competitors provide a variety of presence-sensing and other safety and
security  alternatives such as motion detectors,  CCTV-based  movement detection
systems,  infrared and visible  light beam  detectors,  light  curtains,  on/off
switching mats and pads, tape switches, contact edges, as well as others.

      In the safety and/or  security  sectors,  we compete with  companies  that
include  MillerEdge,  Stanley,  Optex,  Napco,  Pelco, and DMP, along with other
large and  well-established  firms such as Honeywell,  Tyco,  General  Electric,
Bosch and Siemens.

      Many of our competitors have substantially greater development, technical,
marketing,  sales and  financial  resources  than we have.  As a result of these
factors,  competitors  and  potential  competitors  may be able to respond  more
quickly to new or emerging  technologies  and  changes in customer  requirements
and/or to devote  greater  resources to the  development,  promotion and sale of
their  products  and  services  than we can.  We  believe  that our  ability  to
successfully  compete  depends,  to a large degree,  upon the performance of our
technology, our current and planned presence-sensing products and our ability to
finance our development, marketing and distribution efforts.


                                       17


      Patents and  Trademarks - We own Patent No.  5,337,039  issued by the U.S.
Patent  Office  on  August  9,  1994.  In  addition,  we have  five PCTs and one
provisional patent application filed that cover improvements to the InvisaShield
technology.

      We have a  trademark  on our trade  name  "SmartGate"  which we use in our
safety  products  category.  We  have  filed  trademark   applications  for  the
following: "Invisa", "InvisaShield" and the tagline "Safe. Secure. No Question."
We believe  that our patent and  trademark  position  will be  important  in our
efforts to protect our perceived competitive advantages.

      We have the following royalty obligations:

      (i)   We are obligated to pay to Carl Burnett,  the inventor, a royalty of
            the smaller of $1.00 or 1% of the amount  collected from the sale of
            each finished product in which the technology  designed to eliminate
            or filter electronic or mechanical  interference is utilized.  We do
            not  currently  anticipate  using  this  invention  in  our  product
            categories; and

      (ii)  We are obligated to pay a royalty to Pete  Lefferson  equal to 2% of
            net  profits  from  the sale of  InvisaShield  safety  products  for
            parking  gates,  sliding gates and overhead  doors to an independent
            engineering consultant.

MATERIALS AND MANUFACTURING

      We believe that the materials  required and the sources of such  materials
will be similar for our various  existing and planned  product  categories.  All
components  and parts are  modified  or  manufactured  by third  parties  to our
specifications or are otherwise generally available as off-the-shelf  materials.
Our  products  have a number  of  components  including  proprietary  electronic
circuitry  manufactured to our specifications by third party manufacturers and a
standard  power  supply  available in the  marketplace.  The antenna is standard
wire, tape or other metallic  materials,  which are generally purchased in bulk.
Whenever  possible,   we  use  fixed  price  manufacturing  for  our  electronic
circuitry,  placing the responsibility for component supply on the manufacturer.
We  believe  that  there  are  multiple  manufacturers  and  suppliers  for each
component  and that  adequate  components  and  materials  will be  available to
support our planned  growth.  We perform some final  assembly and  predetermined
quality control procedures in our facility.

GOVERNMENT REGULATION

      The use of radio  frequency or "RF",  such as that  incorporated  into our
safety  products,  is regulated  by the Federal  Communication  Commission.  Our
subsidiary, Radio Metrix Inc. submitted its patented technology for required FCC
testing and, in August of 1993, Radio Metrix Inc. received FCC Certification. We
will endeavor to continue satisfying all requirements of the FCC.

      On March 1, 2001, a new safety  standard was  implemented by  Underwriters
Laboratory  (UL)  for  the  powered  gate,  door  and  window   industry.   This
Underwriters  Laboratory Rule, UL-325, while not a governmental  regulation,  is
considered  an  indication of  reasonable  safety for powered  gates,  doors and
windows,  and is a requirement  for UL  certification  for certain powered gate,
door and window  operators.  Gate and operator  manufacturers  that rely upon UL
certification or consider UL  certification  important for components will, most
likely,  require  that our  products be UL certified  before  incorporating  our
products as original  equipment.  Likewise,  the absence of UL certification for
our  products  may  represent  a sales or  marketing  barrier in certain  market
categories and to certain customers.


                                       18


      We plan to apply for UL  certification  for certain of our safety products
(those which we believe meet or exceed the current UL 325  standard).  From time
to time, we anticipate  submitting  additional  products,  including  safety and
security products, for UL certification.  Other markets may have governmental or
certification requirements.

WARRANTY

      Our  safety  products  are sold  with a 90-day  (upgradeable  to one year)
limited  warranty.  A warranty  policy for security  products is currently being
developed.

EMPLOYEES

      We have eight employees,  of whom one is part time. As of the date of this
filing,  we had no unions and we had not entered into any collective  bargaining
agreement  with  any  group  of  employees.  We  believe  that  we  have  a good
relationship with our employees.

FACILITIES

      We lease  approximately  15,200 square feet of  manufacturing,  marketing,
development and office space in one building located in Northgate Business Park,
Sarasota, Florida. No zoning or other governmental requirements are required for
the continued use of our facilities.  We rent our facilities on a month-to-month
basis and the  annual  rent  payments  for the  Company's  facilities  aggregate
$112,872 plus taxes,  which we believe to approximate  the local market rate for
such facilities. The facilities are rented from a non-affiliated party.

      The lease provides an option to purchase the building; however, we have no
current  plans to  execute  the  option.  With the  exception  of the  potential
exercise  of the  options  contained  in the  lease,  we have  adopted  a policy
pursuant to which we do not invest in real estate, interest in real estate, real
estate  mortgages or  securities  issued based upon real estate  activities.  We
maintain  lease  insurance  that  we  believe  is  adequate.  We  are  currently
evaluating  whether  or not to  continue  our  current  lease,  as our needs are
evolving  and there may be  attractive  alternatives  for office and  production
space available in the local market that would be well suited to our needs.

LEGAL PROCEEDINGS

      We, from time to time, are subject to litigation related to claims arising
out of our operations in the ordinary  course of business.  At this time,  there
are no claims asserted, which management believes, taken in the aggregate, would
have a  material  adverse  impact  on our  financial  condition  or  results  of
operations.


                                       19


                                 USE OF PROCEEDS

      We will not  receive  any  proceeds  from the sale of the shares of common
stock by selling  stockholders.  We will,  however,  receive  proceeds  upon the
exercise of the  warrants.  Should all of the  warrants be  exercised,  we would
receive an aggregate  of  $1,500,000.  We will pay all the expenses  incident to
this registration. We plan to use any net proceeds received upon the exercise of
the warrants for general corporate purposes.

      Since the  proceeds of  exercise  of warrants  will be paid to us, our net
tangible  book  value will be  increased  by the sale of shares  underlying  the
warrants covered by this  prospectus.  It is noted that our current net tangible
book value is negative.


                                       20


                              SELLING STOCKHOLDERS

      The following table sets forth each stockholder who is offering his shares
of our common  stock for sale under this  prospectus,  any  position,  office or
other  material  relationship  which such  selling  stockholder  has had with us
within the past three  years,  the  amount of shares  owned by such  stockholder
prior to this offering, the amount to be offered for such stockholder's account,
the amount to be owned by such stockholders following completion of the offering
and (if one  percent  or more) the  percentage  of the class to be owned by such
stockholder after the offering is complete. The prior-to-offering figures are as
of August  31,  2004.  All share  numbers  are based on  information  that these
stockholders  supplied to us. This table assumes that each stockholder will sell
all  of  its  shares  available  for  sale  during  the   effectiveness  of  the
registration  statement  that includes  this  prospectus.  Stockholders  are not
required to sell their shares.  Beneficial ownership is determined in accordance
with Commission  rules and  regulations and includes voting or investment  power
with respect to the securities.

      The number of shares that any selling stockholder will own at any time are
subject to limitation in the certificate of designations  governing the Series A
Preferred Stock and in the warrants,  respectively, so that the aggregate number
of shares of common  stock of which such  selling  stockholder  and all  persons
affiliated with such selling stockholder  (calculated  pursuant to Rule 13d-3 of
the  Securities  Exchange Act of 1934,  as amended)  does not at any time exceed
9.99% of our then outstanding common stock.

      The  percentage  interest  of each  selling  stockholder  is  based on the
beneficial  ownership  of such  selling  stockholder  divided  by the sum of the
current  outstanding  shares of common stock plus the additional shares, if any,
which would be issued to such  selling  stockholder  (but not any other  selling
stockholder) when exercising warrants or other rights in the future.

shares of our common stock as determined  under Section 13(d) of the  Securities
Exchange Act of 1934. As a result of these  provisions,  such entities  disclaim
beneficial  ownership in excess of 9.99% of the outstanding shares of our common
stock.


                                       21


The  information  contained  in this table  reflects  "beneficial"  ownership of
common  stock  within the  meaning of Rule 13d-3 under the  Exchange  Act. As of
August  31,  2004,  we  had  19,473,332  shares  of  common  stock  outstanding.
Beneficial ownership information reflected in the table includes shares issuable
by us upon the exercise of outstanding warrants.

                              PLAN OF DISTRIBUTION

      In this section of the prospectus,  the term "selling  stockholder"  means
and  includes:  (1) the persons  identified  in the tables  above as the selling
stockholders; and (2) any of their donees, pledgees,  distributees,  transferees
or other  successors  in  interest  who may (a) receive any of the shares of our
common stock offered  hereby after the date of this  prospectus and (b) offer or
sell those shares hereunder.

      The shares of our common stock offered by this prospectus may be sold from
time to time directly by the selling  stockholders.  Alternatively,  the selling
stockholders  may from time to time  offer  such  shares  through  underwriters,
brokers, dealers, agents or other intermediaries. The selling stockholders as of
the date of this  prospectus  have advised us that there were no underwriting or
distribution  arrangements entered into with respect to the common stock offered
hereby. The distribution of the common stock by the selling  stockholders may be
effected:  in  one or  more  transactions  that  may  take  place  on the  OTCBB
(including one or more block transaction)  through customary brokerage channels,
either through brokers acting as agents for the selling stockholders, or through
market makers, dealers or underwriters acting as principals who may resell these
shares on the OTCBB;  in  privately-negotiated  sales;  by a combination of such
methods;  or by other means. These transactions may be effected at market prices
prevailing  at the time of sale,  at prices  related to such  prevailing  market
prices or at other  negotiated  prices.  Usual  and  customary  or  specifically
negotiated brokerage fees or commissions may be paid by the selling stockholders
in connection with sales of our common stock.

      The  selling  stockholders  have  agreed not  initiate  short sales of our
common  stock.   However,  the  selling  stockholders  may  enter  into  hedging
transactions with  broker-dealers in connection with distributions of the shares
or otherwise. In such transactions,  broker-dealers may engage in short sales of
the shares of our  common  stock in the course of  hedging  the  positions  they
assume with the selling  stockholders.  The selling  stockholders may enter into
option or other transactions with  broker-dealers  which require the delivery to
the  broker-dealer  of shares of our common stock.  The  broker-dealer  may then
resell or  otherwise  transfer  such  shares of common  stock  pursuant  to this
prospectus.

      The  selling  stockholders  also may lend or pledge  shares of our  common
stock to a broker-dealer.  The broker-dealer may sell the shares of common stock
so lent,  or upon a default the  broker-dealer  may sell the  pledged  shares of
common  stock  pursuant  to this  prospectus.  Any  securities  covered  by this
prospectus  which  qualify for sale  pursuant to Rule 144 may be sold under Rule
144 rather than  pursuant to this  prospectus.  The  selling  stockholders  have
advised us that they have not entered  into any  agreements,  understandings  or
arrangements with any underwriters or broker-dealers regarding the sale of their
securities.  There is no underwriter or coordinating broker acting in connection
with the proposed sale of shares of common stock the selling stockholders.


                                       22


      Although the shares of common  stock  covered by this  prospectus  are not
currently being  underwritten,  the selling  stockholders or their underwriters,
brokers,  dealers  or other  agents or other  intermediaries,  if any,  that may
participate  with the selling  stockholders  in any offering or  distribution of
common stock may be deemed  "underwriters"  within the meaning of the Securities
Act and any  profits  realized  or  commissions  received  by them may be deemed
underwriting compensation thereunder.

      Under applicable rules and regulations  under the Exchange Act, any person
engaged in a  distribution  of shares of the common stock offered hereby may not
simultaneously  engage in market  making  activities  with respect to the common
stock for a period of up to five days preceding such  distribution.  The selling
stockholders  will be subject to the  applicable  provisions of the Exchange Act
and  the  rules  and  regulations  promulgated  thereunder,   including  without
limitation  Regulation M, which provisions may limit the timing of purchases and
sales by the selling stockholders.

      In order to comply  with  certain  state  securities  or blue sky laws and
regulations, if applicable, the common stock offered hereby will be sold in such
jurisdictions only through registered or licensed brokers or dealers. In certain
states, the common stock may not be sold unless they are registered or qualified
for  sale  in  such  state,   or  unless  an  exemption  from   registration  or
qualification is available and is obtained.

      We will  bear  all  costs,  expenses  and  fees  in  connection  with  the
registration  of  the  common  stock  offered  hereby.   However,   the  selling
stockholders  will bear any brokerage or  underwriting  commissions  and similar
selling expenses, if any, attributable to the sale of the shares of common stock
offered pursuant to this prospectus.

      We have agreed to indemnify  certain of the selling  stockholders  against
certain  liabilities,  including  liabilities  under the  Securities  Act, or to
contribute  to  payments to which any of those  stockholders  may be required to
make in respect thereof.

statement  of  which  this  prospectus  forms  a  part,  and by  the  applicable
provisions of Nevada law.

      We are  authorized  to issue up to  100,000,000  shares of  capital  stock
authorized of which 95,000,000 are common stock,  with a par value of $0.001 per
share, and 5,000,000  shares of "blank check" preferred stock,  with a par value
of $0.001 per share.  There are currently  19,473,332 shares of common stock and
22,000 shares of preferred stock issued and outstanding as of August 31, 2004.

COMMON STOCK

      Subject to the rights of holders of preferred  stock,  if any,  holders of
shares of our common stock are entitled to share equally on a per share basis in
such dividends as may be declared by our board of directors out of funds legally
available  therefore,  if at all.  There are presently no plans to pay dividends
with  respect  to  the  shares  of  our  common  stock.  Upon  our  liquidation,
dissolution  or winding up, after payment of creditors and the holders of any of
our senior  securities,  including  preferred  stock, if any, our assets will be
divided  pro rata on a per share  basis  among the  holders of the shares of our
common  stock.  Our common  stock is not  subject to any  liability  for further
assessments.  There are no conversion or redemption  privileges  nor any sinking
fund  provisions  with  respect to our common  stock.  The holders of our common
stock do not have any pre emptive or other subscription rights.

      Holders of shares of our common  stock are  entitled  to cast one vote for
each share held at all  stockholders'  meetings for all purposes,  including the
election of directors. The common stock does not have cumulative voting rights.


                                       31


      All of the issued  and  outstanding  shares of our common  stock are fully
paid, validly issued and non assessable.

DIVIDENDS

      The payment of  dividends,  if any, in the future,  rests  within the sole
discretion of our board of directors.  The payment of dividends will depend upon
our earnings,  our capital requirements and our financial condition,  as well as
other  relevant  factors.  We have not  declared  any cash  dividends  since our
inception,  and we have no present intention of paying any cash dividends on our
common stock in the foreseeable future.

PREFERRED STOCK

      Our Articles of  Incorporation  authorize the issuance of 5,000,000 shares
of "blank check" preferred stock, with a par value of $0.001 per share, of which
22,000 shares  (designated Series A Preferred Stock) were issued and outstanding
as of August 31, 2004.  Our Board has the authority,  without  further action by
the holders of our  outstanding  common  stock,  to issue  additional  shares of
preferred  stock from time to time in one or more classes or series,  to fix the
number of shares  constituting any class or series and the stated value thereof,
if  different  from the par  value,  and to fix the terms of any such  series or
class, including dividend rights, dividend rates, conversion or exchange rights,
voting  rights,   rights  and  terms  of  redemption   (including  sinking  fund
provisions),  the redemption price and the liquidation  preference of such class
or series.

SERIES A PREFERRED STOCK

      On August  16,  2004 the  Company  completed  the  issuance  of twenty two
thousand  (22,000)  shares of Series A Convertible  Preferred  Stock  ("Series A
Preferred Stock").  Following are certain of the significant terms of the Series
A Preferred Stock.

      PROCEEDS FROM FINANCING:  The Series A Preferred Stock bears a face amount
of $2,200,000. Of the gross proceeds, we received $1,937,000 (net of $263,000 in
transaction expenses). $1,158,200 of the proceeds were paid to us at closing and
the  remaining  $778,800 is required to be paid by no later than  September  15,
2004.

      TYPE OF  SECURITY:  The Series A Preferred  Stock is  non-voting,  and are
entitled to dividends only when, or if, declared by our board of directors.

      CONVERSION:  Any issued and outstanding shares of Series A Preferred Stock
may, at the option of the holder,  be converted at any time or from time to time
into fully paid and non-assessable  shares of common stock at a conversion price
equal to eighty percent (80%) of the volume  weighted  average  trading price of
the common stock during the ten trading days  preceding the time of  conversion,
subject to a floor of $0.50 per share and a ceiling of $1.17 per share.


                                       32


      ANTI-DILUTION PROTECTION:  The Certificate of Designations of the Series A
Preferred  Stock  provides  that in the event that we issue stock in  connection
with a  dividend,  distribution,  classification,  merger or  consolidation  the
number  of  shares  of  common  stock  that  the  Series  A  Preferred  Stock is
convertible  into  will  be  adjusted  accordingly.   Additionally,  in  certain
circumstances,  issuances below the then current  conversion  price will entitle
the holders of the Series A Preferred  Stock to weighted  average  anti-dilution
protection.

      LIQUIDATION  PREFERENCE:  In the event of any dissolution or winding up of
the company, whether voluntary or involuntary, holders of each outstanding share
of Series A Preferred  Stock will be entitled to be paid first out of the assets
of the company  available for  distribution  to  stockholders an amount equal to
$100.00 per share of Series A Preferred  Stock held, and any declared but unpaid
dividends on such share,  before any payment shall be made to the holders of the
common stock.

WARRANTS

      As part of our  August,  2004  financing,  we  issued 3 year  warrants  to
purchase  1,500,000  shares of our common  stock at $1.00 per share.  The shares
issuable upon exercise of the warrants  have been  registered as a  registration
statement on Form SB-2, of which this prospectus is a part.

TRANSFER AGENT

      Our  transfer  agent is  Liberty  Transfer  Co.,  274B  New  York  Avenue,
Huntington, New York 11743.

              DISCLOSURE OF COMMISSION POSITION OF INDEMNIFICATION
                         FOR SECURITIES ACT LIABILITIES

      Pursuant to the Nevada  General  Corporation  Law, our bylaws  provide for
indemnification  of our officers,  directors and others who become a party to an
action  provided they acted in good faith and reasoned the conduct or action was
in the best interest of the Company.  Further, the Company maintains officer and
director liability insurance. Insofar as indemnification for liabilities arising
under the  Securities  Act of 1933 may be permitted to  directors,  officers and
controlling  persons of the small  business  issuer  pursuant  to the  foregoing
provisions, or otherwise, the small business issuer has been advised that in the
opinion of the  Securities  and  Exchange  Commission  such  indemnification  is
against  public  policy  as  expressed  in the  Securities  Act of 1933  and is,
therefore, unenforceable.

            MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

      The following  discussion and analysis of our financial condition and plan
of operations  should be read in  conjunction  with our  consolidated  financial
statements and related notes appearing elsewhere in this filing. This discussion
and analysis contains  forward-looking  statements  including  information about
possible or assumed  results of our  financial  conditions,  operations,  plans,
objectives and performance that involve risk, uncertainties and assumptions. The
actual   results  may  differ   materially   from  those   anticipated  in  such
forward-looking  statements.  For  example,  when we indicate  that we expect to
increase  our  product  sales  and  potentially   establish  additional  license
relationships,   these  are  forward-looking   statements.   The  words  expect,
anticipate,   estimate  or  similar   expressions  are  also  used  to  indicate
forward-looking statements.


                                       33


LIMITED OPERATING HISTORY; BACKGROUND OF OUR COMPANY

      We  are a  development-stage  company,  and  we  expect  to  continue  the
commercialization  of our InvisaShield  technology.  For the twelve months ended
December 31, 2003,  we had revenue  from product  sales of $212,679  principally
representing  sales of our  product for powered  parking  gates.  In addition to
limited  revenue,  these sales have  continued to provide  field-testing  of the
reliability  and market  acceptability  of our  technology  and safety  product,
together  with   relationships   with  customers,   dealers,   distributors  and
manufacturers.

      The  financing  for our  development  activities to date has come from our
limited sales,  the sale of common stock,  notes,  short-term  financing,  and a
license  payment.  We expect  to  increase  our  product  sales and  potentially
establish additional license  relationships.  Further, we expect to complete the
development of additional safety and security products and bring them to market.

      We expect to fund our future development activities and operations largely
from the sale of common stock until such time that funds  provided by operations
are sufficient to cover these activities.

      Since we have had a limited history of operations,  we anticipate that our
quarterly results of operations will fluctuate significantly for the foreseeable
future.  We believe that  period-to-period  comparisons of our operating results
should not be relied upon as  predictive  of future  performance.  Our prospects
must be considered in light of the risks, expenses and difficulties  encountered
by  companies  at  an  early  stage  of  development,   particularly   companies
commercializing new and evolving technologies such as InvisaShield.

      On February 9, 2000 in connection with our acquisition of SmartGate, L.C.,
we acquired the license for the  InvisaShield  technology for safety products in
the powered  closure  industry.  On February 26, 2002, we acquired  Radio Metrix
Inc.,  the owner of the  InvisaShield  technology  and patents  from  affiliated
parties.  This acquisition resulted in our expanding our business to include the
development of presence-sensing products for security,  government and all other
markets.  At that time, we also changed our name from  SmartGate Inc. to Invisa,
Inc.

      In February 2004, the Company negotiated a revision to its patent payment,
reducing it from $600,000 to $250,000,  due as follows:  $100,000 by February 8,
2004;  $75,000 by March 8, 2004; and $78,600  (including  interest of $3,600) by
April 22, 2004. All of such payments have been made.

LIQUIDITY AND CAPITAL RESOURCES

      Since  inception  (February  12, 1997),  we have  financed our  operations
largely from the sale of common stock.  From inception  through June 30, 2004 we
raised cash of $10,507,412 net of issuance costs,  through private placements of
common  stock.  At June 30,  2004,  we had cash  and cash  equivalents  totaling
$10,996.


                                       34


      From inception through June 30, 2004, we incurred approximately $3,087,468
of research and development expenses.  These research and development costs were
directed principally toward our InvisaShield(TM) technology and safety products.
Management   estimates  that  sixty  percent  (60%)  was  expended   toward  the
development of our core presence  sensing  technology,  twenty percent (20%) was
expended in the  miniaturization  of our  circuitry,  fifteen  percent (15%) was
expended in the design and development of safety products, and five (5%) percent
was  expended  in the design and  development  of  additional  products  for the
security  sector of our  business.  Accordingly,  we  currently  view  ourselves
primarily as a safety products company. We view the prospects for application of
our  InvisaShield  technology to the Homeland Defense and other similar security
areas on a longer term basis.

      On February 9, 2000, we purchased SmartGate, L.C. The total purchase price
for SmartGate,  L.C. was the issuance of 7,743,558 shares of Invisa, Inc. common
stock to  members  of  SmartGate,  L.C.  representing  approximately  74% of our
outstanding  common  stock at that date.  SmartGate,  L.C.  was the acquirer for
accounting  purposes  and, as such,  our  operations  reflect the  operations of
SmartGate, L.C. since its inception.

      On February  26,  2002,  we acquired  Radio  Metrix Inc.  (the  "Merger"),
principally from affiliated  parties.  We paid the following  purchase price for
Radio Metrix  Inc.:  (i)  3,685,000  shares of  restricted  common  stock;  (ii)
$1,300,000  payable by two promissory  notes;  (iii) a 7% royalty on all revenue
earned from the sale of  products  based upon the Radio  Metrix Inc.  technology
other than safety  products which  constituted the Company's core business prior
to the Merger; and (iv) certain future contingent consideration.  In April 2003,
the Radio Metrix Inc. Purchase  Agreement was amended whereby the Company agreed
to issue  3,250,000  shares of its  common  stock for full  satisfaction  of the
future contingent  consideration.  In November 2003, the Purchase  Agreement was
further  amended whereby the $1,300,000  notes payable were forgiven.  In August
2004, we negotiated the cancellation of the 7% royalty agreement in exchange for
300,000  shares of common  stock.  As a part of this latter  amendment,  certain
other notes receivable from and compensation owed to the affiliated parties were
forgiven. See Item 6 "Management's Discussion and Analysis or Plan of Operations
- -  Liquidity  and  Capital  Resources"  of our Form  10-KSB for a more  detailed
description of the transaction.

      At June 30,  2004,  we had a  $150,000  bank  line of  credit,  which  was
personally  guaranteed by a stockholder,  Mr. H.R. Williams.  The line of credit
required  the payment of interest  monthly at prime plus 1%,  which was 5.75% on
June 30, 2004.  The line of credit was renewed at the same rate on July 15, 2003
and matures on July 15, 2004. The current  interest rate is prime plus 1% which,
at July 15, 2003, was 5.75%. The line of credit was extended until August, 2004,
at which time the amount of $148,611 owing under the line of credit was paid.

      On October 28, 2002, we borrowed $200,000 from a non-affiliated party. The
loan's interest note was paid at 15% per annum,  payable in advance. We issued a
four-year warrant,  together with registration  rights commencing after June 28,
2004 to purchase  200,000  shares of our common  stock at an  exercise  price of
$1.00 per share. We pledged 500,000 shares of our common stock as collateral for
the loan, which will be returned to the Company upon loan repayment or delivered
to the lender as full loan  repayment  in the event of default.  Pursuant to the
terms of the loan,  the date for  repayment  of all  principal  and interest was
extended from February 28, 2003 to April 28, 2003,  and in connection  with said
extension,  we issued the lender on February  28,  2003,  a four-year  option to
purchase  50,000  shares of our common  stock at an exercise  price of $1.00 per
share,  with registration  rights.  We borrowed an additional  $100,000 from the
non-affiliated party in 2003. The terms of this additional advance are currently
under discussion,  but are believed to be substantially  similar to those of the
original $200,000 borrowing.  The $200,000 was subsequently paid in October 2003
by the lender  exercising  the rights  under the pledge in the amount of 500,000
shares of common stock.  The  additional  $100,000 was  subsequently  settled in
August 2004 for $90,000.


                                       35


      For the period January through June 2004, we sold 705,750 shares of common
stock at prices ranging from $1.50 to $3.00 per share aggregating $1,470,932 net
of transaction costs.

      In February 2004, we negotiated a revision to our note payable  related to
the  acquisition  of our patent,  reducing it from $600,000 to $250,000,  due as
follows:  $100,000 by February 8, 2004; $75,000 by March 8, 2004; and $75,000 by
April 8, 2004. All such payments have been made.

      We have  incurred  significant  net  losses and  negative  cash flows from
operations  since our  inception.  As of June 30,  2004,  we had an  accumulated
deficit of $22,116,987 and a working capital deficit of $1,537,192.

      We  anticipate  that  cash used in  product  development  and  operations,
especially in the marketing,  production and sale of our products, will increase
significantly in the future.

      We will be dependent upon our existing cash and cash equivalents, together
with  anticipated  net  proceeds  from  private  placements  of common stock and
potential  license  fees,  and sales of our  products  to  finance  our  planned
operations through at least the next 12 months.  Accordingly,  we plan to access
additional cash from a variety of potential sources,  which may include:  public
equity financing,  private equity financing, license fees, grants, and public or
private  debt.  The Report of  Independent  Registered  Public  Accounting  Firm
included in our Form 10-KSB included a going concern  modification  for the year
ended  December 31,  2003.  Subsequent  to December  31, 2003,  the Company sold
705,750  shares  of  common  stock for cash  totaling  approximately  $1,971,000
(principally  from the  exercise of warrants)  through June 30, 2004.  In August
2004,  the Company  completed a financing  transaction  whereby it will  receive
approximately  $1,937,000  net of  transaction  expenses  (See  "Description  of
Securities - "Preferred Stock").

      Additional  capital may not be  available  when  required or on  favorable
terms. If adequate funds are not available,  we may be required to significantly
reduce or refocus our  operations or to obtain funds through  arrangements  that
may require us to relinquish rights to certain or potential  markets,  either of
which could have a material adverse effect on our business,  financial condition
and  results of  operations.  To the extent  that  additional  capital is raised
through the sale of equity or convertible debt securities,  the issuance of such
securities would result in ownership dilution to our existing stockholders.


                                       36


FOR THE SIX MONTHS ENDED JUNE 30, 2003 COMPARED TO THE SIX MONTHS ENDED JUNE 30,
2004.

      Net Sales and Gross Profit - During the six months ended June 30, 2003 and
2004, net sales totaled $99,997 and $70,397, respectively. The decrease resulted
from a decrease in the sales of safety  products for powered parking gates and a
decrease in the sales of security  devices.  These decreases were offset in part
by an increase in the sale of overhead door sensor devices. We had gross profits
of  $45,914  and  $27,387  for the six  months  ended  June 30,  2003 and  2004,
respectively.

      Research and  Development  Expenses - During the six months ended June 30,
2003 and 2004, research and development  expenses totaled $244,554 and $263,047,
respectively.  The increase of $18,493 principally  resulted from the write down
of  inventory  largely  offset by a  reduction  in rental  space lease costs and
reductions in insurance, salaries and wages, and professional fee expenses.

      Selling, General and Administrative Expenses - During the six months ended
June 30, 2003 and 2004,  selling,  general and  administrative  expenses totaled
$1,570,922 and  $1,510,704,  respectively.  The decrease of $60,218  principally
resulted from  cutbacks in  advertising,  marketing  and  tradeshow  activities,
reductions in compensation and related payroll expenses, rent, insurance, office
supplies and patent amortization expenses.  These reductions were largely offset
by an increase in professional consulting fees.

      Debt  Extinguishment Gain - During the six months ended June 30, 2004, the
Company  negotiated the settlement of the SDR Metro,  Inc.  obligation  from the
contractual amount of $600,000 to a restructured amount of $250,000.

      Interest  Expense,  Net - During  the six months  ended June 30,  2003 and
2004,  net interest  expense  totaled  $229,853 and $18,703,  respectively.  The
decrease of $211,150 resulted  principally from a reduction of the Radio Metrix,
Inc. debt, the SDR Metro,  Inc. debt, as well as  amortization of original issue
discounts during the six months ended June 30, 2003.

      Net Loss and Net Loss Per Common  Share - The  Company's  net loss and net
loss per common share for these periods  decreased from  $1,999,415 and $0.14 to
$1,415,067 and $0.07, respectively, as a result of the matters described above.

YEAR ENDED DECEMBER 31, 2003 COMPARED TO THE YEAR ENDED DECEMBER 31, 2002

      Net Sales and Gross Profit - During the years ended  December 31, 2002 and
2003, net sales totaled $257,118 and $212,679 respectively. The decrease was due
to the  decrease in sales of safety  products  for powered  parking  gates.  The
Company's sales to date have been limited and constrained by lack of capital. We
had a gross  profit of $81,218 for the year ended  December 31, 2002 and $83,708
for the year ended December 31, 2003.


                                       37


      Research and  Development  Expenses - During the years ended  December 31,
2002 and 2003, research and development  expenses totaled $660,844 and $558,277,
respectively.  The  decrease of $102,607 was due  principally  to a reduction in
work force  resulting  in  decreases  in salaries  and wages and payroll  taxes;
partially  offsetting  these  decreases  was rent expense  which  increased as a
result of adding facility space in the second half of 2002.

      Administrative  Expenses - During the years  ended  December  31, 2002 and
2003,  these  expenses  totaled  $2,813,897  and  $5,179,864  respectively.  The
increase of $2,365,967 was attributable to the following  categories:  increases
were due substantially to patent amortization,  and related legal expenses; fees
related to a cancelled  equity funding line;  consultation  fees and expenses in
connection with investor  relations;  recruiting fees in connection with the new
COO,  and office and  insurance  expenses.  Decreases  were due to  reduction of
officer's salaries in connection with  restructuring and severance  settlements;
lower  marketing,  advertising and tradeshow  activities;  and reduction in work
force resulting in decreases in compensation expense.

      Impairment  of Patent - During the year 2003,  the Company  decreased  the
carrying  amount of its patent costs by  $5,517,808 to reflect the fair value as
determined by a third-party valuation. The patent impairment results principally
from  perceived  shifts in  markets  requiring  us to rely  more on our  patents
applied for and less on the original patent.

      Interest  Expense - Net - During the years  ended  December  31,  2002 and
December  31,  2003,  net  interest   expense  totaled   $187,663  and  $565,864
respectively. The increase was due principally to additional interest expense in
connection  with  the  RMI  acquisition  notes  payable  and  certain  financing
transactions occurring in 2003.

      Net Loss and Net Loss Per Common  Share - The  Company's  net loss and net
loss per common share increased from $3,581,186 or $.28 per share to $11,738,105
or $.73 per share,  respectively,  as a result of the matters  explained  above,
including the $5,517,808 write down of the patent.

CRITICAL ACCOUNTING ESTIMATES

      Patents and  Trademarks - The recorded  cost of the patent is based on the
fair  value  of  consideration  paid  for it.  The  ultimate  consideration  was
originally based on a valuation performed by a third party and approved by those
Board  Members  with no  affiliation  with the  seller.  The  patent  costs  are
amortized over the remaining life of the patent at the date of its  acquisition.
The fair value of the patent is reviewed for  recoverability  whenever events or
changes  in   circumstances   indicate  that  its  recorded  value  may  not  be
recoverable. At December 31, 2003, the carrying amount of the patent was reduced
by  approximately  $5,518,000 to reflect its fair value as determined by a third
party valuation. The patent impairment results principally from perceived shifts
in market  requiring us to rely more on our patents  applied for and less on the
original patent.


                                       38


                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      To the best of our knowledge, other than as set forth below, there were no
material  transactions,  or series of  similar  transactions,  or any  currently
proposed  transactions,  or series of similar transactions,  to which we were or
are to be a party, in which the amount involved  exceeds  $60,000,  and in which
any director or executive officer,  or any security holder who is known by us to
own of record or beneficially  more than 5% of any class of our common stock, or
any  member of the  immediate  family of any of the  foregoing  persons,  has an
interest.

      Pursuant to a merger, on February 26, 2002, we acquired Radio Metrix Inc.,
a  Florida  corporation.  Radio  Metrix  Inc.  was  formed  in 1992  by  certain
individuals who founded  SmartGate,  L.C. Radio Metrix Inc. became the exclusive
worldwide licensee of the InvisaShield technology in 1992. It began research and
development  efforts following  obtaining the exclusive worldwide license and in
1997, granted a sublicense limited to powered closure applications to SmartGate,
L.C. The assets of Radio Metrix Inc.  were  acquired  more than two years before
its  acquisition  by  Invisa,  with the  exception  of a patent.  The patent was
purchased  by Radio  Metrix  Inc.  on  January  8, 2002  pursuant  to a Purchase
Agreement  dated October 9, 2000.  The purchase  price paid by Radio Metrix Inc.
for the patent was  $1,200,000 of which $50,000 was paid by Radio Metrix Inc. as
a deposit  against  the  purchase  price.  The Radio  Metrix Inc.  agreement  to
purchase the patent required a closing,  with payment, by January 8, 2002, which
was before the  closing of the  planned  acquisition  of Radio  Metrix  Inc.  by
Invisa.  Accordingly,  as part of its  acquisition of Radio Metrix Inc.,  Invisa
loaned  approximately  $550,000 to Radio Metrix Inc. to enable Radio Metrix Inc.
to timely close its purchase of the patent by paying the remaining  $550,000 due
at closing.  In acquiring Radio Metrix Inc.,  Invisa  acquired  ownership of the
patent and the $550,000 loan to Radio Metrix Inc. became an  intercompany  debt.
The purchase price paid by the Company for Radio Metrix Inc. is discussed  later
in this  section.  Reference is made to Note B to the financial  statements  for
additional  information  regarding the  Company's  $550,000 loan to Radio Metrix
Inc.

      Pursuant  to  this  acquisition,  Radio  Metrix  Inc.  was  merged  into a
subsidiary,  which we incorporated  specifically for this  transaction.  Because
each of the Radio Metrix Inc.  stockholders had pre-existing  relationships with
us, the  transaction  was approved by the Board Members  having no  affiliation,
stock ownership or other  relationship  with Radio Metrix Inc. (the "Independent
Committee of Directors'). The Independent Committee of Directors was represented
by legal counsel.  Additionally, it received advice as to the financial fairness
of the transaction from a national firm  experienced in financial  valuation and
consulting.  The  relationships  of  our  officers,   directors  or  substantial
stockholders with Radio Metrix Inc. at the date of the acquisition were:

      At the closing of Invisa's  purchase of Radio Metrix Inc.,  the patent was
subject  to a  previous  pledge  as  collateral  for a  twenty-four  (24)  month
Promissory  Note in the  principal  amount of $600,000,  which was made by Radio
Metrix Inc.  when it  purchased  the  patent.  The party that sold the patent to
Radio  Metrix  Inc.  was not  affiliated  with  either  the  Radio  Metrix  Inc.
stockholders  or Invisa.  As a further result of the acquisition of Radio Metrix
Inc.,  the Company  eliminated  its  obligation  to pay ongoing  royalty fees in
connection  with its sale of  powered  closure  safety  products  based upon the
InvisaShield  technology  while  expanding  its  access to all  presence-sensing
market categories outside of safety, including access to the security market and
other markets (Technology Purchase from Radio Metrix Inc.).

      The  aggregate  consideration  paid for the  purchase of Radio Metrix Inc.
through December 2003 was: (i) 3,685,000 shares of restricted common stock; (ii)
$1,300,000  (plus accrued and unpaid  interest)  payable by two promissory notes
consisting of: (a) a $500,000 promissory note, payable at 10% interest per annum
until  August 25,  2003,  at which time the  interest  rate  becomes  15%.  This
promissory  note is due in one  installment  on February  25,  2006;  and (b) an
$800,000 promissory note payable at 15% interest due monthly,  and all principal
due in one  installment  on February  25,  2004.  Both  promissory  notes may be
prepaid without penalty. Neither promissory note is collateralized;  and (iii) a
7% royalty on all revenue  earned from the sale of products based upon the Radio
Metrix  Inc.  technology  other  than  safety  products  which  constituted  the
Company's  core business  prior to the Merger.  The royalty may be terminated by
the Company for a one-time payment based upon appraisal. Additionally, Note B to
the financial  statements  details  obligations of Radio Metrix Inc.,  including
approximately  $175,000 in accrued compensation payable to stockholders of Radio
Metrix  Inc.  that  remained  in place and was  assumed  by the  Company  at the
acquisition of Radio Metrix Inc. As a result of an Amendment to the Radio Metrix
Inc. Merger Agreement,  no earn-out or other  consideration  will be paid by the
Company except as described above.


                                       40


      In November 2003, the Company and two principal  stockholders entered into
new  agreements to forgive and  restructure  certain notes  receivable and notes
payable,  including those in connection with the Radio Metrix Inc.  transaction.
(See Item 6  "Management's  Discussion  and  Analysis  for Plan of  Operations -
Liquidity and Capital Resources").

      Pursuant to an  agreement  made in 1992  between  Radio Metrix Inc. and an
individual who introduced Radio Metrix Inc. to the inventors of the InvisaShield
technology,  Radio  Metrix Inc. was  obligated to pay up to $200,000  contingent
upon sales.  Under the Agreement,  the obligation  terminates  when Radio Metrix
Inc.  has  paid  an  aggregate  of  $200,000.  The  obligation  arose  out of an
introduction  to the  inventors  of the Radio  Metrix  Inc.  Technology  and the
anticipation  of future  assistance  to be provided by the finder in  connection
with  the  commercialization  of the  technology.  In 1999,  as a result  of the
unavailability  of the  finder,  and the lack of any  ongoing  support  from the
finder,  Radio Metrix Inc.  asserted breach of the Agreement and provided notice
of termination. The termination has not been contested.

      On February 9, 2000, we purchased  SmartGate,  L.C.  principally  from the
same group of related  parties  that  previously  owned  Radio  Metrix Inc. As a
result,  on February 9, 2000, we issued  7,743,558 shares of Invisa common stock
to the  SmartGate,  L.C.  members  which  represented  approximately  74% of our
outstanding  capital  stock at that date.  As a result of this  transaction,  we
agreed to  subsequently  make loans to certain of the  SmartGate,  L.C.  members
should same be  required  to fund IRS  recapture  tax  obligations  imposed as a
result of this transaction.  As a result of this obligation, in October 2001, we
loaned approximately  $74,384 to Mr. Michael,  and approximately  $71,810 to Mr.
Duffey, pursuant to unsecured five-year Promissory Notes.

      We have the following royalty obligations:

      (i) We are  obligated to pay to Carl Burnett,  the inventor,  a royalty of
the smaller of $1.00 or one percent (1%) of the amount  collected  from the sale
of each finished product in which the technology designed to eliminate or filter
electronic  interference is used. In instances where we license this technology,
independent  of our other  technology,  a royalty of 10% of the licensed fees or
royalties  received is due. In instances where we license this invention as part
of further potential technology other than the InvisaShield,  a royalty of 1% of
the  licensed  fees or  royalties  received is due. We  currently  utilize  this
invention only in our safety products and we do not currently  anticipate  using
this invention in other product categories;

      (ii) We are  obligated  to pay a royalty  equal to two percent (2%) of net
profits from the sale of InvisaShield safety products for parking gates, sliding
gates and overhead doors, and all other authorized products using the technology
worked on by an independent engineering consultant, Pete Lefferson.


                                       41


      (iii) We were  obligated to pay a royalty  equal to seven  percent (7%) of
revenue to  affiliated  parties with regard to all  categories  of our business,
other than the safety category.  This obligation arose from the consideration to
be paid by us in the business  combination  transaction  with Radio Metrix Inc.,
which has been  previously  discussed  above.  This  royalty-based  payment  was
terminated by us in August, 2004, in consideration for the issuance of five year
warrants  to purchase  up to 400,000  shares of our common  stock at an exercise
price of $1.75 per share. The warrants expire in five (5) years.

      The following  officers or directors and  principal  stockholders  entered
into  loan  transactions  associated  with the  purchase  of common  stock  with
SmartGate,  L.C.  before  it  was  acquired  by us and  became  a  wholly  owned
subsidiary.  As a result  of  these  pre-acquisition  transactions,  we have the
following notes  receivable:  Stephen A. Michael - $375,000,  Samuel S. Duffey -
$375,000  and Edmund C. King -  $210,000.  The notes with  Messrs.  Michael  and
Duffey were waived as part of the restructuring and severance agreements.

      One of  the  Company's  principal  stockholders  is  H.R.  Williams  ("Mr.
Williams") and his family limited partnership,  the H.R. Williams Family Limited
Partnership ("HRW Partnership"). The Company's transactions with Mr. Williams or
the HRW Partnership are summarized below:

      1. In March  1999,  Mr.  Williams  subscribed  for  446,804  shares of the
Company's wholly owned subsidiary,  SmartGate, L.C. As part of the subscription,
Mr.  Williams:  (a) paid $59,523 in cash; (b) agreed to loan the Company $25,000
pursuant to a Promissory Note with interest at prime ("the $25,000  Note");  (c)
agreed to sublease SmartGate, L.C. space to conduct its operations in a building
leased by the HRW Partnership;  and (d) agreed to guarantee a line of credit for
SmartGate,  L.C.  at the  Regions  Bank in  Bradenton,  Florida in the amount of
$150,000 ("Credit Facility"). As part of the Subscription Agreement,  SmartGate,
L.C. granted the HRW Partnership (see Security  Ownership of Certain  Beneficial
Owners and Management) an option to purchase  446,804 shares at a purchase price
of $1.07 per share. The Option will remain  exercisable  until the last to occur
of: (i) 245 days  following  either the  Company's  payoff of a Credit  Facility
guaranteed by H.R. Williams;  (ii) the date Mr. Williams guarantee of the Credit
Facility is released;  or (iii) one year  following the date when certain shares
owned by Mr. Williams or HRW Partnership are free of transfer restrictions.

      2. In May 2001,  the Company  issued 164,799 shares of its common stock to
the HRW Partnership as its landlord.  Pursuant to the Sublease Agreement entered
into between SmartGate,  L.C. and the HRW Partnership as landlord in March 1999,
SmartGate,  L.C. was granted the right to pay its rent to the HRW Partnership as
landlord,  either in cash or in stock, and if paid in stock, it would be paid at
the rate of one share  for each  $0.50 of rent  owed.  For the  period  from the
inception of the Lease in March 1999 through August 2000, the Company elected to
pay the  approximate 19 months of rent with stock  resulting in this issuance of
164,799  shares  to  the  HRW  Partnership  as  landlord.   This  Agreement  has
terminated.

      3. In March 2002, the Company repaid the $25,000 Note in full.


                                       42


      4. At December  31, 2003,  the Company had a $150,000  bank line of credit
(which was substantially  all drawn upon) guaranteed by a stockholder,  Mr. H.R.
Williams.  The line of credit requires the payment of interest  monthly at prime
plus 1% which was 5.75% at December  31,  2003.  The line of credit was extended
until August 2004, at which time the amount of $148,611  owing under the line of
credit was paid.

      In 2002, we issued a stock option entitling G.M. Capital Partners, Ltd., a
consultant in international  investor  relations,  to purchase 500,000 shares of
the Company's common stock at $3.50 per share, with certain  registration rights
attached,  was issued in  prepayment  of the  consulting  fee for the year.  The
agreed value of the stock option and the consulting  services was established at
$120,000.  The stock option is considered  fully vested and will be  exercisable
until  December 31, 2005.  Provided that the shares which may be purchased  upon
the  exercise  of  the  stock  option  have  not  been  covered  by  a  previous
Registration  Statement,  the holder may,  commencing  on January 1, 2004 demand
that the Company file and exercise  reasonable  efforts to effect a Registration
Statement  covering  250,000  shares.  Additionally,  provided  that all 500,000
shares which may be purchased  under the stock option have not been covered by a
previous  Registration  Statement,  commencing  on July 1, 2005 the  holder  may
demand  that the  Company  file and  exercise  reasonable  efforts  to  effect a
Registration  Statement  covering  the  remaining  250,000  shares  which may be
purchased upon the exercise of the stock option.  Both  Registration  Statements
shall be at the cost of the Company.  In April 2003,  the Company issued 500,000
shares of its authorized but unissued common stock to GM Capital Partners,  Ltd.
in  recognition  of its  support in the  Company's  past and  current  access to
capital and matters related thereto.

      In  connection  with  the  August,  2004  financing,   we  negotiated  the
cancellation of $776,132 in accrued compensation to certain directors,  officers
and former employees in exchange for 300,000 shares of common stock to be issued
between June 1, 2005 and January 20, 2006.

ORGANIZATION WITHIN LAST FIVE YEARS

      Stephen  A.  Michael,  Samuel S.  Duffey  and  Robert  T.  Roth  (recently
deceased)  may be  considered  founders or  promoters  of  SmartGate,  L.C.  The
consideration paid to these individuals is discussed herein. Bob Knight and G.M.
Capital  Partners,  Ltd. may be considered  founders or promoters of the Invisa,
Inc. Discussion of the consideration received by them is discussed herein.

      On September  13, 2004,  the closing bid and closing ask prices for shares
of our common stock in the  over-the-counter  market, as reported by NASD OTC BB
were $0.59 and $0.65 per share, respectively.

      We believe that there are presently 27 market makers for our common stock.
When stock is traded in the public market,  characteristics of depth,  liquidity
and  orderliness of the market may depend upon the existence of market makers as
well as the presence of willing  buyers and sellers.  We do not know if these or
other market makers will continue to make a market in our common stock. Further,
the trading volume in our common stock has  historically  been both sporadic and
light.

      As of July 31, 2004, we had an aggregate of 413  stockholders of record as
reported by our transfer agent,  Liberty Transfer Co. Certain shares are held in
the "street" names of securities broker dealers and we do not know the number of
stockholders which may be represented by such securities broker dealer accounts.

DIVIDEND POLICY

      The payment by us of  dividends,  if any, in the future,  rests within the
sole discretion of our board of directors.  The payment of dividends will depend
upon our earnings, our capital requirements and our financial condition, as well
as other relevant  factors.  We have not declared any cash  dividends  since our
inception,  and have no present  intention  of paying any cash  dividends on our
common stock in the foreseeable future.

             Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Invisa, Inc.

      We have  audited  the  consolidated  balance  sheets of  Invisa,  Inc.  (a
development  stage  enterprise) as of December 31, 2002 and 2003 and the related
consolidated statements of operations,  stockholders' equity, and cash flows for
the years then ended.  These financial  statements are the responsibility of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audits.

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

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Invisa, Inc. as
of December 31, 2002 and 2003 and the  consolidated  results of  operations  and
cash flows for the years then ended in  conformity  with  accounting  principles
generally accepted in the United States of America.

      The accompanying financial statements have been prepared assuming that the
Company will  continue as a going  concern.  As discussed in Note C, the Company
incurred a net loss during the year ended December 31, 2003 of  $11,738,105  and
for the period February 12, 1997 (date of inception)  through  December 31, 2003
of  $20,701,920.  These  factors,  among  others as  discussed  in Note C to the
financial  statements,  raise  substantial  doubt about the Company's ability to
continue as a going concern.  Management's  plans in regard to these matters are
also  described  in  Note  C.  The  financial  statements  do  not  include  any
adjustments that might result from the outcome of this uncertainty.

                                  Invisa, Inc.
                        (A Development Stage Enterprise)
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (Including Notes Applicable to Unaudited Periods)

NOTE A - DESCRIPTION OF ORGANIZATION AND BUSINESS

      Invisa,  Inc.  (formerly  known as  "SmartGate,  Inc.") ("the  Company" or
"Invisa") is a development  stage  enterprise  that  incorporates  safety system
technology and products into automated  closure devices,  such as parking gates,
sliding gates,  overhead garage doors and commercial  overhead doors. Invisa has
also  demonstrated  production-ready  prototypes  of security  products  for the
museum and other markets.  The Company has not fully  implemented  its sales and
marketing plan and has, therefore, not emerged from the development stage.

      For the year ended  December  31,  2002,  the Company was related  through
common  ownership  to Radio  Metrix Inc.  (RMI),  which since 1992 has owned the
licensing rights to the underlying  technology used by Invisa and since 2000 has
owned the right to purchase the underlying  patent from an unrelated  party. The
patent was  purchased  by RMI in January  2002 for $1.2  million  consisting  of
$600,000  in cash,  which  was  principally  borrowed  from the  Company,  and a
$600,000 note. The Company purchased RMI in February 2002 (see Note B).

NOTE B - BUSINESS COMBINATIONS AND PATENT IMPAIRMENT

Purchase of SmartGate L.C.

      Effective  February 9, 2000,  the Company  acquired all of the  membership
units of SmartGate L.C. in exchange (the Exchange) for  approximately  7,744,000
shares  of  common  stock,  representing  75%  of  the  Company's  common  stock
outstanding at that time. Prior to the Exchange,  Invisa, Inc. (a privately held
company formed in February 1997) had substantially no operations. For accounting
purposes,  the Exchange was recorded as a reverse  acquisition,  with  SmartGate
L.C.  as  the  accounting  acquirer.  As  a  result,  the  historical  financial
information presented prior to the Exchange is solely that of SmartGate L.C. The
operating  results of Invisa,  Inc.  are combined  with those of SmartGate  L.C.
following the Exchange.

Purchase of RMI

      In February 2002, the Company  purchased 100% of the  outstanding  capital
stock of RMI, a company owned by the principal  stockholders of Invisa, Inc. RMI
had virtually no operations since its inception and, therefore,  the Company has
determined  that by  acquiring  RMI,  the  Company  acquired  intangible  assets
(patents and patents  under  development)  and not a business.  At closing,  the
Company issued two promissory notes totaling $1,300,000 ($500,000 payable in one
installment  48 months from the  closing  with  interest  payable  monthly,  and
$800,000  payable in one  installment  14 months from the closing with  interest
payable  monthly;  and issued  435,000 shares of Invisa common stock (see Note O


                                      F-8

for restructuring).  The $800,000 note maturity date was subsequently amended to
mature  on April  25,  2004.  The  Company  also  agreed  to pay to the  sellers
royalties of 7% of all revenue  generated from the RMI technology  (exclusive of
safety  applications).  The revenue  agreement is effective until  terminated by
mutual   agreement  of  the   respective   parties.   Additionally,   contingent
consideration to be paid by the Company was as follows prior to amendment:

o     Upon  the  emergence  from  the  development  stage  of the  product  line
      incorporating RMI security technology.

      (a)   a  $4,500,000  promissory  note  payable in one  installment  due 60
            months from the first commercial sale with accrued  interest.  While
            outstanding,  the  promissory  note may,  at the  discretion  of the
            holder, be converted into shares of Invisa, Inc. common stock at the
            conversion ratio of one share of Invisa,  Inc. common stock for each
            $5.00 of principal and interest.

      (b)   1,125,000  shares of Invisa common stock,  which may be increased by
            the Board of Directors of Invisa,  Inc. in order that the  aggregate
            market  value of the  shares  issued is at least  $4,500,000  on the
            issuance date.

o     3,750,000 shares of Invisa, Inc. common stock, upon the first to occur (i)
      $25,000,000 in revenue from RMI  technology  (security  technology),  (ii)
      $4,000,000 in pre-tax  profits from RMI technology  (security  technology)
      and earned royalties, (iii) any 30-day period during which Invisa's common
      stock has an average closing price which exceeds $15.00 per share, or (iv)
      a change in control.

      Invisa  initially  recorded the cost of the patent,  which consists of the
consideration  paid, the  liabilities  assumed,  and the fair value of the stock
issued  (435,000  shares of  common  stock  based on a $3.50 per share  offering
price) as follows:

Promissory notes issued                       $1,300,000
Stock issued                                   1,522,500
Liabilities assumed (1)                        1,018,257
Costs relating to the acquisition                120,218
                                         --------------------
                                              $3,960,975
                                         ====================

(1)   Liabilities  assumed  includes  $600,000  note payable (see Note Q) to the
      original  owner of the  patent,  $550,000  note  payable  to the  Company,
      $357,000 receivable from the Company, $175,000 payable to the shareholders
      of RMI and $50,000 of other liabilities.

                                  Invisa, Inc.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (Including Notes Applicable to Unaudited Periods)

NOTE B - BUSINESS COMBINATIONS AND PATENT IMPAIRMENT - Continued

      The Company  obtained a  third-party  valuation  of RMI as of  acquisition
date,   which   supports  the  initial   purchase   price  plus  the  contingent
consideration referred to above.

      During  April 2003,  through an amendment  to the  agreement,  the Company
agreed to issue  3,250,000  shares of its common stock for full  satisfaction of
the contingent  consideration  referred to above.  These shares were recorded at
the fair value at that date of $3.00 per share and, as a result, patent cost was
increased by $9,750,000  with a  corresponding  increase in  additional  paid-in
capital.  During November 2003,  $1,169,131 of the $1,300,000  Promissory  Notes
plus accrued interest were forgiven by the holders (See Note O).

      The Company follows the  methodology  presented in SFAS 144 to measure for
impairment  of the  patent.  At  December  31,  2003,  the  Company  recorded an
impairment charge of approximately $5,518,000 based upon a third-party valuation
of the patent.  The valuation was based  principally upon discounted  forecasted
cash flows. The change in estimated future cash flows that resulted in the lower
patent  value is  associated  with  increased  reliance on  distributor  license
arrangements in place of a portion of previously  forecasted  direct sales.  The
asset  group value  includes  the patent  acquired  in  February  2002 and other
patents under  development.  The Company will continue to monitor its actual and
forecasted results of operations and will consider them in its future impairment
analyses.

NOTE C - OPERATING MATTERS

      The accompanying financial statements have been prepared assuming that the
Company will continue as a going  concern.  For the year ended December 31, 2003
and since the date of inception,  the Company has had a net loss of  $11,738,105
and $20,701,920,  respectively. For the six months ended June 30, 2004 and since
the date of inception  for the period then ended,  the Company has a net loss of
$1,415,067 and $22,116,987,  respectively.  As of June 30, 2004, the Company has
not emerged  from the  development  stage and has  negative  working  capital of
approximately $1,537,192.  In view of these matters,  recoverability of recorded
property and equipment,  intangible  assets and other asset amounts shown in the
accompanying  financial  statements is dependent upon continued operation of the
Company, which in turn is dependent upon the Company improving its overall level
of  profitability.  Since  inception,  the Company has financed  its  operations
principally from the sale of equity securities, as the Company has not generated
significant  revenues  from the sales of its  products.  The Company  intends on
financing  its future  development  activities  and its  working  capital  needs
largely from the sale of equity  securities  with some  additional  funding from
other traditional financing sources,  including increasing the available line of
credit,  term notes and proceeds from licensing  agreements until such time that
funds   provided  by  operations   are   sufficient  to  fund  working   capital
requirements.  Subsequent to December 31, 2003,  the Company sold 705,750 shares
of common stock for cash totaling approximately $1,971,000 (principally from the
exercise  of  warrants)  through  June 30,  2004.  In August  2004,  the Company
completed  a  financing   transaction  whereby  it  will  receive  approximately
$1,937,000 net of transaction expenses (See Note Q).

                (Including Notes Applicable to Unaudited Periods)

NOTE C - OPERATING MATTERS - Continued

      In addition,  the Company is in licensing fee  discussions  with potential
distributors of the Company's  future security  products.  While there can be no
assurance  that such  sources will provide  adequate  funding for the  Company's
operations,  management  believes  that such  sources  will be  available to the
Company.

NOTE D - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

      The  consolidated  financial  statements as of December 31, 2002 and 2003,
and June 30, 2003 and 2004,  include the accounts of Invisa and its wholly owned
subsidiaries,   SmartGate,   L.C.  and  RMI.  All   intercompany   balances  and
transactions have been eliminated.

Use of Estimates

      In preparing the  consolidated  financial  statements  in conformity  with
accounting  principles  generally  accepted  in the  United  States of  America,
management  makes estimates and assumptions  that affect the reported amounts of
assets and liabilities  and disclosures of contingent  assets and liabilities at
the  date  of the  financial  statements,  as well as the  reported  amounts  of
revenues and expense  during the reporting  period.  Actual results could differ
from those estimates and assumptions.

Cash and Cash Equivalents

      The Company  considers  all highly liquid  investments  with a maturity of
three months or less when purchased to be cash equivalents.

Accounts Receivable

      Accounts   receivable  are  due  primarily  from  companies  in  the  gate
manufacturing  industry  located  throughout  the  United  States and the United
Kingdom.  Credit is extended based on an evaluation of the customers'  financial
condition  and,  generally,  collateral  is not required.  Account  balances are
evaluated for  collectability  based on the condition of the  customers'  credit
including  repayment  history  and trends and  relative  economic  and  business
conditions.  Bad debts have not been  significant.  For the years ended December
31, 2002 and 2003, a customer located in the United Kingdom accounted for 0% and
16% ,  respectively,  of total Company sales.  For the six months ended June 30,
2003 and 2004, such sales were nominal

Inventories

      Inventories are stated at the lower of cost or market.  Cost is determined
using a method, which approximates the first-in, first-out method.

Furniture, Fixtures and Equipment

      Furniture,  fixtures,  and equipment are  depreciated  on a  straight-line
basis over their  estimated  useful  lives,  principally  five years.  Leasehold
improvements  are amortized  over the term of the lease or the estimated  useful
lives,  whichever is shorter.  Accumulated  depreciation  and  amortization  was
$57,460 and $97,597 at December 31, 2002 and 2003  ($117,029 at June 30,  2004),
respectively. Accelerated methods are used for tax depreciation.

Patent

      The patent for the  Company's  underlying  technology  is  amortized  on a
straight-line  method over 10 years,  which represents the remaining life of the
patent at its  purchase  date in  February  2002.  Accumulated  amortization  at
December 31, 2002 and 2003 totaled  $319,600 and $1,493,659  ($1,887,777 at June
30,  2004),  respectively.  At  December  31,  2003,  the  Company  recorded  an
impairment   charge  of  approximately   $5,518,000  that  is  included  in  the
consolidated statement of operations.

Revenue

      Sales  under fixed  price  arrangements  are  recognized  as revenue  upon
shipment of product (when title  transfers to the purchaser) and  collectability
is assured.

      In July of 2002, the Company entered into a five-year agreement with Rytec
Corporation, whereby Rytec became the exclusive licensee in North America to use
the  Company's  safety  technology  for  certain  industrial  doors.  Under  the
agreement,  Rytec paid the Company  $300,000 which represents an advance payment
to be applied towards the purchase of the first 3,000 units by Rytec. As of June
30, 2004, no sales transactions had occurred under the agreement.

Research and Development Costs

      Research and  development  costs consist of direct and indirect costs that
are associated with the development of the Company's technology. These costs are
expensed as incurred.

Advertising Costs

      The Company expenses advertising costs as incurred. During the years ended
December  31,  2002 and 2003,  advertising  expense  was  $267,532  and  $62,901
($33,701  and  $0.00  for  the  six  months  ended  June  30,  2003  and  2004),
respectively.

Warranty Costs

      Estimated  warranty costs are recognized in the period product is shipped.
However, there have been no significant warranty costs incurred through June 30,
2004,  nor  are  any  significant   amounts  expected  to  occur   subsequently.
Accordingly, no warranty liability has been recognized for any period presented.

Income Taxes

      The Company applies Statement of Financial Accounting Standards (SFAS) No.
109, Accounting for Income Taxes.

Financial Instruments

      The Company's  financial  instruments  include cash and cash  equivalents,
accounts  receivable  and  accounts  payable.  The  carrying  amounts  of  these
financial instruments approximate their fair value, due to the short-term nature
of these  items.  The carrying  amounts of the line of credit and notes  payable
approximate their fair value due to the use of market rates of interest.

Impairment of Long-Lived Assets

      The Company evaluates the recoverability of its long-lived assets or asset
groups,  including  patents,  whenever  adverse  events or changes  in  business
climate  indicate  that the  expected  undiscounted  future  cash flows from the
related asset may be less than previously anticipated.  If the net book value of
the related asset exceeds the  undiscounted  future cash flows of the asset, the
carrying  amount would be reduced to the present  value of its  expected  future
cash  flows or other  measure  of fair  value and an  impairment  loss  would be
recognized.  At December 31, 2003, the Company recorded an impairment  charge of
approximately  $5,518,000,  which  was  based on the  results  of a  third-party
valuation of the patent and patents under  development.  The value of the patent
and patents under  development  will continue to be sensitive to the achievement
of  forecasted  revenue and related  cash flows.  Accordingly,  management  will
continue to compare its actual to budgeted results during 2004 and will consider
unfavorable variances in future impairment analysis.

Earnings per Common Share

      Basic and diluted  earnings per share are  computed  based on the weighted
average  number of common stock  shares  outstanding  during the period.  common
stock  equivalents are not considered in the calculation of diluted earnings per
share for the periods presented because their effect would be anti-dilutive.

Stock Based Compensation

      The Company follows Statement of Financial  Accounting  Standards No. 123,
Accounting for Stock-Based  Compensation  (SFAS 123),  which  establishes a fair
value based method of accounting for stock-based  employee  compensation  plans;
however,  the Company has elected to account for its employee stock compensation
plans using the intrinsic value method under Accounting Principles Board Opinion
No. 25, with pro forma  disclosures of net earnings and earnings per share as if
the fair value based method of accounting  defined in SFAS 123 had been applied.
The Company  amortizes  compensation  costs related to the pro forma  disclosure
using the straight-line  method over the vesting period of the employees' common
stock options.

      Had compensation  cost for the Company's stock option plan been determined
on the fair  value at the grant  dates  for  stock-based  employee  compensation
arrangements  consistent with the method required by SFAS 123, the Company's net
loss and net  loss per  common  share  would  have  been the pro  forma  amounts
indicated below (see also Note M):

New Accounting Pronouncements

      In  January  2003,  FASB  Interpretation  46,  Consolidation  of  Variable
Interest Entities an  Interpretation  of ARB No. 51 ("FIN 46") was issued.  This
Interpretation clarified the application of Accounting Research Bulletin ("ARB")
No. 51, Consolidated  Financial Statements,  to certain entities in which equity
investors do not have the characteristics of a controlling financial interest or
do not have  sufficient  equity at risk for the entity to finance its activities
without   additional   subordinated   financial   support  from  other  parties.
Application  of the majority  voting  interest  requirement in ARB 51 to certain
types of  entities  may not  identify  the party  with a  controlling  financial
interest  because the  controlling  financial  interest may be achieved  through
arrangements that do not involve voting interests. All enterprises with variable
interests in variable  interest  entities  created after January 31, 2003, shall

NOTE D - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

apply the provisions of this  Interpretation  to those entities  immediately.  A
public entity with a variable  interest in a variable  interest  entity  created
before  February 1, 2003,  shall  apply the  provisions  of this  Interpretation
(other than the transition disclosure provisions in paragraph 26) to that entity
no later than the  beginning  of the first  interim or annual  reporting  period
beginning after June 15, 2003. A nonpublic entity with a variable  interest in a
variable  interest  entity  created  before  February  1, 2003,  shall apply the
provisions  of  this  Interpretation   (other  than  the  transition  disclosure
provisions  in  paragraph  26) to that entity no later than the end of the first
annual reporting period beginning after June 15, 2003.

      In  December  2003,  a revision  to FIN 46 ("FIN  46R") was  published  to
clarify some of the  provisions of FIN 46 and exempt  certain  entities from its
requirements.  Under FIN 46R, a legal entity is  considered a variable  interest
entity of "VIE",  with some exceptions if specific  criteria are met, if it does
not have sufficient equity at risk to finance its own activities without relying
on financial support from other parties.  Additional criteria must be applied to
determine if this condition is met or if the equity  holders,  as a group,  lack
any one of three stipulated characteristics of a controlling financial interest.
If the legal entity is a VIE,  then the  reporting  entity  determined to be the
primary beneficiary of the VIE must consolidate it. Even if the reporting entity
is not obligated to consolidate the VIE, then certain  disclosures  must be made
about the VIE if the reporting entity has a significant  variable interest.  The
effective  date of the  interpretation  was modified  under FIN 46R. A reporting
entity  is  required  to  apply  the  provisions  of FIN  46R to all  VIEs  that
previously were subject to certain  previously issued special purpose entity, of
SPE,  accounting  pronouncements for all reporting periods ending after December
14,  2003.  For all other  VIEs,  a  reporting  entity is  required to adopt the
provisions of FIN 46R for all reporting  periods after May 15, 2004. The Company
does not  believe it has  ownership  in any  variable  interest  entities  as of
December  31,  2003.  The Company  will apply the  consolidation  or  disclosure
requirements  of this  interpretation  in future  periods  if it should  own any
interest deemed to be a variable interest entity.

Unaudited Financial Statements

      The unaudited financial  statements and the related notes thereto for June
30,  2003 and 2004,  include all normal  recurring  adjustments,  which,  in the

NOTE H - NOTES PAYABLE TO RELATED PARTIES AND NOTES PAYABLE - Continued

      In October  2002,  the Company  borrowed  $200,000  from a  non-affiliated
party. The loan bore interest at 15% per annum,  payable in advance. The Company
issued a four-year warrant,  together with registration  rights commencing after
June 28, 2004, to purchase  200,000  shares of common stock at an exercise price
varying from $1.00 to $3.00 per share depending upon the date of loan repayment.
Based on the unpaid  status of the notes,  the exercise  price of the warrant is
$1.00 per share.  As a result of this  transaction,  the Company  recognized  an
original  issue discount of $144,000.  Included in interest  expense are $58,000
and $86,000 arising from the amortization of the original issue discount in 2002
and 2003,  respectively.  The Company  pledged 500,000 shares of common stock as
collateral  for the loan,  which was to be  returned  to the  Company  upon loan
repayment  or  delivered  to the lender as full loan  repayment  in the event of
default.  Those shares were not recognized as issued and outstanding at December
31, 2002 or 2003. All principal and interest were initially  payable on February
28,  2003,  subject to  extension  to April 28,  2003,  upon the  issuance  of a
four-year option to purchase an additional 50,000 shares at $1.00 per share. The
loan was subsequently increased to $300,000.  During 2003, the $200,000 loan was
paid by the lender  exercising  the rights  under the pledge in exchange for the
500,000  shares of common stock.  The  remaining  $100,000 was settled in August
2004 for $90,000 cash.

NOTE I - DUE TO STOCKHOLDERS AND OFFICERS

      Due to stockholders and officers consists principally of deferred payments
of  base   compensation   and  severance   amounts   payable  to  two  principal
stockholders. The amounts payable are non-interest bearing (see Note O).

expense  for each of the five years  ending  December  31, 2008 will be $812,121
annually.  As described in Note D, the Company recorded an impairment  charge to
the patent of approximately $5,518,000 during the fourth quarter of 2003.

      Options and warrants to purchase  3,621,129 and 7,238,931 shares of common
stock as of December 31, 2002 and 2003 are not considered in the  calculation of
diluted loss per share  because the effect would be  anti-dilutive.  Options and
warrants to purchase  3,826,129 and 7,926,514 shares of common stock, as of June
30, 2003 and 2004,  are not  considered in the  calculation  of diluted loss per

NOTE L - COMMON STOCK

      In March 2001,  the Company  authorized a private common stock offering of
up to 1,500,000 shares at $3.50 per share (the "March 2001  Offering").  Related
to the March 2001  Offering,  the Company  issued 412,325 shares of common stock
and  realized  proceeds of  $1,210,749  during 2002 (net of $232,389 in offering
costs).  In April 2002,  the March 2001 Offering was terminated and in May 2002,
the Company  commenced a new offering  consisting  of up to 3,000,000  shares of
common stock at $5.00 per share (the "May 2002 Offering"). The May 2002 Offering
was amended to comprise only  1,000,000  units at a purchase  price of $5.00 per
unit (the "Unit  Offering").  Each unit  consists of one share of the  Company's
common stock, and one warrant to purchase one additional share (the "Unit"). The
exercise  price of each  warrant  shall be $5.00 per share until August 15, 2003
(the "Initial  warrant Year"),  and from August 16, 2003 through August 15, 2004
the exercise price is the greater of the average  closing  trading price for the
Company's  common stock during the initial  warrant year or $8.00,  whichever is
greater. As part of the Unit Offering, the Company has committed to issue to

brokers/dealers  warrants to purchase  common  stock at $5.50 per share equal to
10% of the units  placed.  The Unit Offering was amended to reflect an effective
unit price of $4.00 per share in May 2002.  Under the Unit Offering,  during the
year ended  December  31,  2002,  the Company  issued  83,750 units and realized
proceeds of  $271,450  (net of $63,550 in cash  offering  costs).  In 2002,  the
Company  also issued  93,833  shares of common  stock and  realized  proceeds of
$244,820 (net of $36,680 in offering costs).

      On January 3, 2003, the Company's stockholders approved an increase in the
Company's  authorized  stock to  100,000,000  shares,  consisting  of 95,000,000
Common and 5,000,000  Preferred shares;  rights and preferences of the Preferred
are to be set by the Board of Directors. This authorization was reflected in the
Company's financial statements at December 31, 2003.

During the year 2003,  the Company  entered into the  following  equity  related
transactions:

      For the period January  through  December 2003, the Company sold 1,000,003
shares  of  common  stock at  prices  ranging  from  $1.07 to  $3.00  per  share
aggregating $2,012,619 in cash, net of transaction costs. These transactions and
other non-cash equity transactions are discussed below.

      For the period  January  through  March 2003,  the Company  issued  68,000
shares  of  common  stock at  prices  ranging  from  $1.07 to $3.00  per  share,
aggregating $192,086 in cash, net of transaction costs.

      In April 2003, the Company  entered into a twelve-month  agreement with an
investor, whereby the investor would provide the Company $1,200,000 in cash from
May 2003 to April 2004,  in monthly  payments  ranging from $50,000 to $150,000.
The Company issued 50,000 shares of common stock at $3.00 per share and received
$139,940  (net of costs) on May 1, 2003.  In August  2003,  this  agreement  was
terminated, and the Company issued the investor 50,000 shares of common stock at
$2.00 per share as part of this  termination.  The Company has no  obligation to
repurchase any shares issued to the investor as part of this agreement.  No cash
proceeds were received related to the shares issued for this transaction.

      In April 2003,  the Company  approved  the  issuance of 500,000  shares of
common stock to a third party.  The shares were granted in  recognition  of past
performance  associated  with common stock  private  placement  offerings and in
contemplation  of continued  involvement  by this advisor in future fund raising
activities.  A total value of $1,500,000  was  recognized as additional  paid in
capital  associated with this issuance of common stock. Based on expected future
proceeds from common stock offerings ($5 million), the Company recorded deferred
offering costs of $937,000,  as a reduction to stockholders'  equity  associated
with these  shares.  The  deferred  offering  costs were  being  amortized  as a
reduction to additional  paid-in  capital based on capital  raised in respective
periods.   At  December  31,  2003,  the  deferred   offering  cost  balance  of
approximately  $638,000  was written  off to  expense,  as the amount of capital
raised  during  2003 was  significantly  less than  anticipated.  The  remaining
$862,000  is included as offering  costs in 2003.  In August  2003,  the Company

reduced the  exercise  price from $3.50 per share to $2.00 per share for 500,000
options to purchase common stock granted to the third party.  The revaluation of
these  options  had no  impact on the  Company's  financial  statements,  as the
options were granted in recognition of past  performance  associated with common
stock  private  placement  offerings.  No cash  proceeds  were received for this
transaction.

     In October  2002,  the  Company  borrowed  $200,000  from  Daimler  Capital
Partners  ("Daimler").  All  principal and interest were payable on February 28,
2003,  subject to extension to April 28, 2003,  upon the issuance of a four-year
option to purchase an  additional  50,000  shares at $1.00 per share,  which was
recorded as original issue discount in 2002. The extension option was issued and
the loan was  extended to April  2003.  The  maturity  of the loan was  extended
further and, in May 2003,  the loan was increased by $100,000.  The $200,000 was
subsequently  paid in October 2003 by the lender exercising the rights under the
collateral  pledge in the  amount of  500,000  shares of common  stock.  No cash
proceeds were received related to this transaction.

      During April 2003,  through an amendment  to the 2002 Radio  Metrix,  Inc.
purchase  agreement,  the Company agreed to issue 3,250,000 shares of its common
stock for full  satisfaction of future  contingent  consideration.  These shares
were  recorded  at the fair  value at that  date of $3.00 per  share  and,  as a
result, patent cost was increased by $9,750,000 with a corresponding increase in
stockholders'  equity during April 2003. No cash proceeds were received  related
to this transaction.

      In May 2003,  the  Company  issued  14,285  shares of its  authorized  but
unissued  common  stock  to  Crescent  Fund,  Inc.,  pursuant  to  a  Consulting
Agreement.  These  shares  were  recorded at a fair value of $3.00 per share and
included in selling,  general,  and administrative  expenses.  In July 2003, the
Company issued an additional 14,284 shares of its authorized but unissued common
stock to Crescent Fund, Inc., pursuant to this Consulting Agreement. The Company
may issue  additional  shares of its common stock to Crescent  Fund,  Inc. under
this  Consulting  Agreement.  No cash  proceeds  were  received  related to this
transaction.

      In May 2003,  the Company  entered  into an Equity Line of Credit  ("ELC")
agreement  pursuant to which the Company  borrowed  $250,000.  The borrowing was
convertible into common stock at a 25% discount from the then prevailing  market
price.  The Company had the right,  but not the  obligation,  to sell additional
registered shares under the Agreement at a 25% discount from the then prevailing
market  price to a maximum  of  $1,000,000,  including  the  $250,000  amount if
converted.  The agreement  required a minimum stock price of $2.50 per share and
minimum trading volume requirements,  both as defined in the agreement. Pursuant
to the  Agreement,  the  Company  agreed to issue a warrant to  purchase  75,000
shares of the Company's common stock at an exercise price of $2.76 per share, of
which 25,000  shares are vested and the balance would vest only in the event the
Company  exercises its right to sell additional shares of registered stock under
the Agreement.

      Related  to the ELC,  in July 2003 the  Company  issued  91,638  shares of
common stock and received cash proceeds of $99,908, net of transaction costs. In
July 2003,  the note payable was  converted  into 135,022  registered  shares of
common stock.  The Company  recognized  original issue discount of approximately
$202,000  associated  with the value of warrants and the  contingent  beneficial
conversion  feature of the notes payable.  The Company also recognized  deferred
costs of approximately  $66,000. The discount and loan costs were amortized over
the term of the loan and were subsequently  fully expensed in July 2003 upon the
conversion into common stock. In November 2003, the Company issued an additional
104,167  shares of common stock at a price of $2.40 per share and received  cash
proceeds of $217,396, net of transaction costs.

      In June and July 2003,  the Company sold 350,500  Units at $2.00 per Unit,
each Unit consisting of one share of the Company's  common stock and one warrant
to purchase one additional  share at an exercise  price of $2.00 per share,  one
additional  share at an exercise  price of $3.00 per share,  and one  additional

      In May 2004,  the  Company's  shareholders  approved  the  adoption of the
2003-A Employee, Director,  Consultant and Advisor Stock Compensation Plan which
provides for the reservation of 3,500,000  shares of the Company's common stock.
This Plan also  retained all  provisions  of the 2002 Plan. A total of 1,460,000
Options have been granted under the Plan.

      In May 2004,  the Company  reduced the  exercise  price of 896,500  common
stock  warrants  previously  issued to investors with original  exercise  prices
ranging from $2.00 to $4.00 to an exercise price of $1.50.  The reduction of the
exercise price for these common stock warrants was made as an inducement for the
investors  to exercise  these  warrants  during  fiscal  year 2004.  The Company
accounted  for  the  incremental  fair  value  of  these  warrants,   which  was
approximately  $464,000, as deferred offering costs, with a corresponding credit
to  additional  paid-in  capital.  During the three  months ended June 30, 2004,
190,000 of these warrants were  exercised,  which reduced the offering costs and
additional paid-in capital by approximately $98,000.

NOTE N - COMMITMENTS AND CONTINGENCIES

Operating Leases

      Prior to June 2002,  the Company  subleased its  manufacturing  and office
space under an operating  sublease  agreement from a stockholder.  In June 2002,
the Company  entered into a new two-year  lease with an unrelated  party for its
existing  facility at an annual lease  payment of $103,200  ("New  Lease").  The
lease,  which had an option to purchase the premise during the term at $836,000,
has not been renewed, and the Company is operating on a month-to-month basis. In
March 2002, the Company entered into a two-year lease for additional  facilities
at an  approximate  annual lease payment of $97,200.  The lease has an option to
purchase the property at $698,000  during year one and $750,000 during year two.
During 2003,  the Company  abandoned this facility and accrued for the remaining
lease payment at December 31, 2003.

      The Company is obligated to pay the lesser of $1.00 or 1% of each sale for
products  incorporating  certain electronic or mechanical  interference  related
technology.  The royalty amount is 10% where the Company licenses the technology
to  third  parties.  The  Company  is  also  obligated  to  pay a  royalty  to a
consultant;  an amount equal to 2% of net profits  arising from sales of certain
safety  products.  There are no significant  royalty  obligations for any period
presented.  Subsequent  to June 30,  2004,  substantially  all of the  Company's
royalty  agreements have been terminated  through  settlement  arrangements (See
Note Q).

Legal and Other Matters

      The Company is, from time to time, subject to litigation related to claims
arising out of its  operations in the ordinary  course of business.  The Company
believes  that no such  claims  should  have a  material  adverse  impact on its
financial condition or results of operations.

("Stockholders')   entered  into  agreements   ("Agreements")   to  forgive  and
restructure  certain notes receivable,  certain stock  subscriptions and related
interest  receivable,  notes and related interest payable, and other amounts due
the stockholders. Under the agreements, the following occurred:

     Forgiveness  by the  Company  of two  notes  receivable  from  Stockholders
     totaling $146,310 ($161,000 at December 31, 2002).

     Forgiveness  by the Company of stock  subscriptions  receivable and accrued
     interest from the Stockholders  totaling $923,432 ($885,000 at December 31,
     2002).

     Forgiveness by the  Stockholders of notes payable of $1,169,131 and accrued
interest of $130,601 by the Company.

     Forgiveness by the  Stockholders  of certain  compensation  amounts owed to
them totaling $416,963.

      In connection with these  Agreements,  the Company  recognized  additional

addition to the amounts forgiven, the stockholders agreed to allow approximately
$338,000 of their  accrued  compensation  to be paid on a contingent  basis,  as
described below.

      Effective February 2000, the Company had entered into five-year employment
agreements with the two Stockholders, which provided for each of them to receive
an annual salary of $150,000 ($30,000 of which was deferred), an ongoing monthly
bonus of $2,000,  an annual car allowance of $8,500,  and other fringe benefits.
The  amounts  charged to expense in total for the two  stockholders  under these
employment agreements  approximated $305,000 in 2002 and $286,000 in 2003. Under
the restructuring Agreements, compensation for one of the Stockholders ceased as
of September 30, 2003 and, as of January 31, 2004 for the other Stockholder. The
employment agreements also terminated on those respective dates.

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES

      In the last three  years,  the  Company  sold the  following  unregistered

shares of its common  stock.  Sales were limited to non-US  investors  and there

Rule 506 of Regulation D under the Act.

      In July 2001, the Company,  pursuant to its 2000 Plan, issued an option to
an employee to purchase an aggregate of 100,000  shares at an exercise  price of
$5.32 per share. This option was issued pursuant to Rule 701 of the Act.

                                      II-1


      In December  2001, the Company issued an aggregate of 95,000 shares of its
common stock in stock bonuses to four officers in  recognition of performance in
year 2001.  The  shares had a value of $3.50 per share on the date of grant.  As
the issuance  represented a  transaction  by an issuer (i.e. -- the Company) not
involving any public  offering,  the shares were issued  pursuant to the private
offering exemption set forth in Section 4(2) of the Act.

      In January 2002, Hawk Associates,  Inc., the Company's  domestic  investor
relations'  representative was granted an option to purchase up to 50,000 shares
of the Company's common stock at a purchase price of $7.25 per share. The Option
is exercisable for a period of seven years, and is subject to a vesting schedule
over the initial  24-month  period  where 6,250  shares are  released and become
eligible for purchase at the end of each  quarterly  period  during the 24-month
vesting term,  provided the  Engagement  Agreement  between the Company and Hawk
Associates,  Inc. has remained in effect at the end of the quarterly period then
in effect. There were no underwriters involved in the issuance.  This Option was
issued pursuant to Rule 701 of the Act.

      In July 2003,  the Company agreed to issue to Hawk  Associates,  Inc., the
Company's  domestic investor relations  representative,  37,000 shares of common
stock in payment of $67,000 cash fees and expenses  which had accrued  under the
Company's   agreement  with  Hawk  Associates,   Inc.  pursuant  to  which  Hawk
Associates,  Inc. provides domestic investor relations  services.  There were no
underwriters involved in the issuance. As the issuance represented a transaction
by an issuer (i.e. -- the Company) not involving any public offering, the shares
were issued pursuant to the private offering exemption set forth in Section 4(2)
of the Act.

      In January 2002,  the Company,  pursuant to its 2002 Plan,  which provides
for both qualified and non-qualified options, issued options to purchase a total
of 1,010,000 shares to a total of 17 persons consisting of officers,  directors,
consultants or employees.  The exercise price for 700,000 of the shares is $3.85
per share,  and for the  remaining  310,000  shares is $3.50 per share (of these
options to purchase,  30,000 shares were cancelled).  There were no underwriters
involved in the  issuance.  The Company  issued the options  under the 2002 Plan
pursuant to Rule 701 of the Act.

      In February 2002, the Company issued 435,000 shares of its common stock as
part of the closing of an Agreement of Merger and Plan of  Reorganization by and
among the Company, SmartGate/RadioMetrix Acquisition Corp. and Radio Metrix Inc.
("Merger"). Pursuant to the Merger, additional shares were required to be issued
upon the satisfaction of certain  performance  criteria (the "Earn-Out Shares").
All  potential  Earn-Out  Shares  were  issued in April  2003,  resulting  in an
additional  3,250,000  shares  being  issued  under the  Merger.  There  were no
underwriters involved in the issuance. As the issuance of the shares to the five
RadioMetrix stockholders, pursuant to the Merger represented a transaction by an
issuer (i.e. -- the Company) not involving any public offering,  the shares were
issued pursuant to the private  offering  exemption set forth in Section 4(2) of
the Act (see "Certain Relations and Related Transactions").


                                      II-2


      In May 2002,  in  consideration  for G.M.  Capital  Partner  Ltd.'s ("GM")
consultant  services as  international  relations  consultant in Regulation  "S"
transactions,  the  Company  issued a stock  option  to GM for the  purchase  of
500,000  shares at an exercise  price of $5.50 per share.  The stock  option was
issued in prepayment of the consulting fee for the year. The agreed value of the
stock option and the consulting services was established at $120,000.  The stock
option was amended and restated in November 2002 to change the exercise price to
$3.50 and to extend the term.  In August 2003,  the stock option was amended and
restated to change the exercise price to $2.00. The stock option is fully vested
and exercisable until December 31, 2005. There were no underwriters  involved in
the issuance.  This Option was issued pursuant to Rule 701 of the Act, and as it
represented a  transaction  by an issuer (i.e. -- the Company) not involving any
public  offering,  the option was also issued,  pursuant to the private offering
exemption set forth in Section 4(2) of the Act.

      In June 2002, the Company,  pursuant to its 2002 Plan, issued an option to
purchase  100,000  shares to Gregory  Newell,  a director  of the  Company.  The
exercise price is $5.10 per share.  There were no  underwriters  involved in the
issuance. This option was issued pursuant to Rule 701 of the Act.

      In June 2002, the Company,  pursuant to its 2002 Plan, issued an option to
purchase  20,000  shares to John E.  Scates,  a  director  of the  Company.  The
exercise price is $5.15 per share.  There were no  underwriters  involved in the
issuance. This option was issued pursuant to Rule 701 of the Act.

      In July 2002,  the Company sold 83,750 Units at $4.00 per Unit,  each Unit
consists of one of the  Company's  common  stock and one warrant to purchase one
additional  share.  The exercise  price of each warrant is $5.00 per share until
August 15, 2003 (the "Initial warrant Year"). From August 16, 2003 to August 15,
2004 (the Second warrant  Year"),  the exercise price is the greater of: (i) the
average closing trading price for the Company's  common stock during the Initial
warrant Year, or (ii) $8.00 per share. The warrants are redeemable at the option
of the Company at $0.10 per share upon 30 days  notice to the  holder.  In order
for the Company to exercise its right to redeem: during the Initial warrant Year
the Company's common stock must have traded for 20 consecutive trading days at a
closing  trading price above $10.00 per share, or during the Second warrant Year
the Company's common stock must have traded for 20 consecutive trading days at a
closing trading price above $16.00 per share.  Any warrants not timely exercised
or redeemed automatically expire on August 15, 2004.

      Shares  acquired  upon the exercise of the warrant will not be  registered
with the SEC, unless otherwise determined by the Company in its sole discretion,
and  accordingly,  will bear a  restrictive  legend as to transfer in accordance
with  Rule  144 of the Act.  In the  event of a stock  dividend  or stock  split
resulting in the number of  outstanding  of shares of the Company being changed,
the applicable exercise price and number of shares, as provided in the warrants,
shall be proportionately adjusted. In the event of the merger, consolidation, or
combination  of the Company into another  company or entity which  survives that
transaction,  the shares  which may be  purchased  under the  warrants  shall be
converted into an equivalent  number of shares of the surviving  entity.  In the
event of the sale of all or substantially all of the assets of the Company,  the
shares which may be purchased upon the exercise of the warrants shall be treated
in any  distribution  as if said  shares are issued  and  outstanding,  with the
exception  that the exercise price under the warrants shall be deducted from the
amount to be distributed on a per-share basis. The holders of warrants shall not
be entitled to vote or exercise  other rights of  stockholders  unless and until
the warrants are exercised and the  underlying  shares  issued.  In the event of
redemption  by the Company,  each holder shall be provided 30 days prior written
notice of the Company's intent to redeem,  during which notice period the holder
of the warrant shall be entitled to exercise the warrant.


                                      II-3


      Sales were  limited  to non-US  investors  and there were no  underwriters
involved in the sale of the Units. The Units were sold to one purchaser who is a
suitable and sophisticated  non-U.S.  resident.  The Units were sold for cash at
$4.00 per Unit (initially $5.00 per Unit and  subsequently  reduced to $4.00) at
an aggregate  offering price to date of $335,000 and aggregate  finder's fees of
$33,500, with aggregate offering expenses of $10,050. In addition,  finders were
granted  placement  warrants to purchase an amount of shares equal to 10% of the
Units placed (i.e. - 8,375  warrants).  The per-share  exercise  price of shares
which may be purchased under the placement warrant shall be $5.50. The placement
warrant shall have a term of 60 months and shall not be  exercisable  during the
initial 13 months  following  issuance.  Following the 13-month  non-exercisable
period,  holders,  acting in  unison,  shall have the right on one  occasion  to
demand  that the  Company  file and  exercise  reasonable  efforts  to  effect a
Registration  Statement  covering  the shares  which may be  purchased  upon the
exercise  of the  placement  warrant.  Such right to demand  registration  shall
terminate once the Company files a Registration  Statement for  registration  of
the shares which may be purchased  upon the exercise of the  placement  warrant.
Additionally, following the 13-month non-exercisable period, the holders, acting
in unison,  shall have the right on one occasion to have the shares which may be
purchased upon the exercise of the warrants  included in any other  Registration
Statement  filed by the Company  provided that the inclusion of such shares does
not adversely affect the registration purpose or statement and provided that the
shares have not previously been registered by the Company.

      The Company  conducted  this Unit Offering  pursuant to an exemption  from
registration  for limited  offerings  provided by Rule 506 of Regulation D under
the Act.

      From  October 2002  through  December  31,  2002,  the Company sold 93,833
shares of its common stock,  pursuant to an exemption from registration provided
by  Regulation  S under the Act.  Sales were limited to non-U.S.  investors  and
there were no  underwriters  involved  in the sale.  The shares were sold to six
purchasers who are suitable and  sophisticated  non-U.S.  residents.  The shares
were  sold  for cash at  $3.00  per  share  at an  aggregate  offering  price of
$281,499.  Aggregate  finder's  fees were paid of  approximately  $28,150  (with
aggregate offering expenses of approximately $8,445).

      On October 28, 2002, we borrowed $200,000 from a non-affiliated party. The
loan bears interest at 15% per annum,  payable in advance. We issued a four-year
warrant,  together with  registration  rights  commencing after June 28, 2004 to
purchase  200,000  shares of our common stock at an exercise  price of $1.00 per
share. We pledged 500,000 shares of our common stock as collateral for the loan,
which will be returned to the Company  upon loan  repayment  or delivered to the
lender as full loan repayment in the event of default.  Pursuant to the terms of
the loan, the date for repayment of all principal and interest was extended from
February 28, 2003 to April 28, 2003, and in connection with said  extension,  we
issued the lender, on February 28, 2003, a thirty-eight month option to purchase
50,000  shares of common  stock at an  exercise  price of $1.00 per share,  with
registration rights. There were no underwriters involved in the issuance. As the
issuance  represented  a  transaction  by an issuer  (i.e.  -- the  Company) not
involving any public offering, the shares and option were issued pursuant to the
private offering  exemption set forth in Section 4(2) of the Act. We borrowed an
additional  $100,000 from the  non-affiliated  party in 2003.  During 2003,  the
$200,000 loan was paid by the lender  exercising  the rights under the pledge in
exchange for the 500,000  shares of common  stock.  The  remaining  $100,000 was
settled in August 2004 for $90,000 cash.


                                      II-4


      In January 2003, pursuant to the exercise of an option granted in December
1999, the Company issued to one purchaser, 12,198 shares of the Company's common
stock for an aggregate  exercise  price of $13,000.  There were no  underwriters
involved in the sale. As the issuance  represented  a  transaction  by an issuer
(i.e. -- the Company) not involving any public offering,  the shares were issued
pursuant to the private offering exemption set forth in Section 4(2) of the Act.

      From January 2003 to June 30, 2003,  the Company sold 68,000 shares of its
common stock,  pursuant to an exemption from registration provided by Regulation
S under the Act.  Sales were  limited to  non-U.S.  investors  and there were no
underwriters  involved in the sale. The shares were sold to seven purchasers who
are suitable and sophisticated non-U.S. residents. The shares were sold for cash
at $3 per share at an aggregate  offering price of $204,000.  Aggregate finder's
fees were paid of  approximately  $20,400 (with aggregate  offering  expenses of
approximately $6,120).

      In April 2003,  the Company  issued  500,000  shares of its authorized but
unissued  common stock to GM in recognition of its support in the Company's past
and  current  access to  capital  and  matters  related  thereto.  There were no
underwriters involved in the issuance. As the issuance represented a transaction
by an issuer (i.e. -- the Company) not involving any public offering, the shares
were issued pursuant to the private offering exemption set forth in Section 4(2)
of the Act.

      In April 2003,  Invisa entered into an agreement with Mr. Alan Feldman,  a
non-affiliated  party  ("Agreement").  Pursuant to the  Agreement,  Mr.  Feldman
purchased 50,000 shares of the Company's authorized but unissued common stock at
$3.00 per share.  There  were no  underwriters  involved  in the  issuance.  Mr.
Feldman is a non-US person and the sale was made  pursuant to an exemption  from
registration  provided by  Regulation S under the Act.  Additionally,  in August
2003,  as part of the  termination  of the  Agreement,  the  Company  issued Mr.
Feldman  50,000 shares of the Company's  authorized  but unissued  common stock.
There were no  underwriters  involved in the  issuance.  This  issuance was made
pursuant to the exemption from  registration  provided by Regulation S under the
Act.

      In May and July 2003,  the Company  issued 28,569 shares of its authorized
but unissued common stock to a consultant,  pursuant to a Consulting  Agreement.
There were no underwriters involved in the issuance. As the issuance represented
a  transaction  by an issuer  (i.e.  -- the Company)  not  involving  any public
offering,  the shares were issued pursuant to the private offering exemption set
forth in Section 4(2) of the Act.


                                      II-5


      In May 2003, we entered into an Equity Line of Credit ("ELC") with BarBell
Group Inc.  ("BarBell").  As part of this ELC we borrowed $250,000 from BarBell.
Further, as part of this ELC, we granted a warrant to BarBell to purchase 75,000
shares  of  our  common  stock  with  an  exercise  price  of  $2.76  per  share
("warrant").  25,000 shares are vested under this warrant and the balance of the
shares will vest based upon performance under the ELC as follows:  25,000 shares
will vest once the Company  receives  $500,000  under the ELC and 25,000  shares
will vest once the Company has received an aggregate of  $1,000,000 in financing
under  the ELC.  Additionally,  as part of the  establishment  of the  ELC,  the
Company  issued  4,000  shares of its common  stock to Capstone  Partners LC and
2,000 shares to Crescent  Fund Inc. in payment of a Finders Fee for  introducing
the Company to BarBell.  There were no underwriters involved in the issuances of
the warrant and the Finders Fee shares.  As the  issuance of the warrant and the
Finders Fee shares  represented a transaction by an issuer (i.e. -- the Company)
not involving any public  offering,  these  issuances  were made pursuant to the
private offering exemption set forth in Section 4(2) of the Act. On July 7, 2003
the Company's  Registration  Statement  #333-106439  ("Registration  Statement")
relating to the foregoing ELC transaction and the shares  described above became
effective.  The Company  issued  135,022  shares of its common  stock to BarBell
under the Registration Statement in satisfaction of the $250,000 borrowing which
was  established  in May 2003 as part of the ELC. The proceeds of the stock sale
were used to fund current operations of the Company.  Additionally,  the Company
issued 91,638 shares of its common stock  pursuant to a $100,000  stock purchase
advance by BarBell  under the ELC in July 2003. A finder's fee payment  equal to
13% of the gross proceeds was paid to the aforedescribed  finders.  The proceeds
of this  stock  sale were used to fund  current  operations  of the  Company.  A
Registration Statement filed in September 2003 covers the sales of shares by the
selling  stockholders  including  shares  purchased or which may be purchased by
BarBell  under the ELC;  shares  which may be  purchased  by  BarBell  under the
warrant;  and the shares issued to the two finders. The Company will not receive
any proceeds  from the sale of shares by the selling  stockholders.  In November
2003, the Company issued an additional 104,167 shares of common stock at a price
of $2.40 per share and received  cash  proceeds of $217,396  net of  transaction
costs. The registration statement was terminated in November 2003.

      In May 2003, the Company  granted,  pursuant to its 2003 Plan,  options to
purchase  80,000  shares to Joseph  Movizzo,  a  director  of the  Company.  The
exercise price is $3.00 per share.  The option vests at the rate of 5,000 shares
per  quarter.   The  option  is  exercisable  until  May  2010.  There  were  no
underwriters involved in the issuance. As the issuance represented a transaction
by an issuer (i.e. -- the Company) not involving any public offering, the option
was issued pursuant to the private offering  exemption set forth in Section 4(2)
of the Act.

      In June and July 2003,  the Company  agreed to sell 350,500 Units at $2.00
per Unit at an aggregate offering price of $701,000, each Unit consisting of one
share of the  Company's  common  stock and: one warrant to purchase one share of
common  stock at an exercise  price of $2.00 per share;  one warrant to purchase
one share of common  stock at an  exercise  price of $3.00  per  share;  and one
warrant to purchase one share of common stock at an exercise  price of $4.00 per
share.  The warrants are exercisable  until June 30, 2005. The finder's fee paid
in  connection  with the  sale of these  $2.00  Units is  described  in the next
paragraph.  The sales  were made  pursuant  to an  exemption  from  registration
provided by Regulation S under the Act. Sales were limited to non-U.S. investors
and there are no underwriters involved in the sale. The shares were sold to four
purchasers who are suitable and sophisticated  non-U.S.  residents.  The Company
registered the shares  purchased as part of the $2.00 Units and the shares which
are issuable under the warrants contained in the $2.00 Units in September 2003.


                                      II-6


      In addition to the $2.00  Units  described  in the  paragraph  above,  the
Company,  in July 2003, agreed to issue the finder,  GM, an additional 45,500 of
the $2.00  Units as a finder's  fee.  Of the Units  described  in the  paragraph
above,  GM was  purchaser of 50,500  Units.  The issuance of the $2.00 Units was
made pursuant to an exemption from  registration  provided by Regulation S under
the Act and there are no  underwriters  involved  in the  issuance.  The Company
registered the shares issued as part of the $2.00 Units and the shares which are
issuable under the warrants contained in the $2.00 Units in September 2003.

      In July 2003, we engaged Source Capital Group,  Inc.,  which is registered
as a securities  broker  dealer,  as Invisa's  non-exclusive  financial  advisor
primarily to assist Invisa in raising additional capital. We issued 5,000 shares
of common  stock to Source  Capital  Group,  Inc. as a  retainer.  There were no
underwriters involved in the issuance. As the issuance represented a transaction
by an issuer (i.e. -- the Company) not involving any public offering, the shares
were issued pursuant to the private offering exemption set forth in Section 4(2)
of the Act. The Company  registered  the shares issued to Source  Capital Group,
Inc. in September 2003.

      In July 2003,  the Company agreed to issue to Hawk  Associates,  Inc., the
Company's  domestic investor relations  representative,  37,000 shares of common
stock in payment of $75,000  cash fees,  which had accrued  under the  Company's
agreement with Hawk  Associates,  Inc. No cash proceeds were received related to
this transaction. This agreement was terminated in August 2003.

      Also in July 2003,  we entered into a Consultant  Agreement  with National
Financial Consulting  Corporation,  also referred to as OTC Financial Network, a
Massachusetts  corporation,  to assist us in public  relations  and  stockholder
communications.   Under  this  Consulting  Agreement,  Invisa  granted  National
Financial  Consulting Corp.  options to purchase 100,000 shares of Invisa common
stock at exercise  prices  ranging from $3.00 per share to $4.50 per share.  The
Agreement has since been terminated.


                                      II-7



      Pursuant to an agreement between NFC and its  subcontractor,  Gary Geraci,
NFC instructed  the Company to issue 1/2 of the Options  directly to Mr. Geraci.
Accordingly, the Options are issued as follows:

    NFC                                             Gary Geraci
         12,500 options @ $3.00                         12,500 options @ $3.00

         12,500 options @ $4.50                         12,500 options @ $4.50

      There were no  underwriters  involved in the  issuances.  As the issuances
represented a  transaction  by an issuer (i.e. -- the Company) not involving any
public  offering,  the  Options  were issued  pursuant  to the private  offering
exemption  set forth in Section  4(2) of the Act.  The  Company  registered  the
shares  issuable under the warrants in September  2003, and  accordingly,  these
shares are included in this Registration Statement.

      In August  2003,  the  Company  granted GM a warrant to  purchase  100,000
shares of Invisa common stock at $3.00 per share. The option is fully vested and
exercisable  until  August  2006.  There were no  underwriters  involved  in the
issuance.  As the issuance  represented a transaction  by an issuer (i.e. -- the
Company) not involving any public  offering,  the shares were issued pursuant to
the private offering exemption set forth in Section 4(2) of the Act. The Company
registered the shares issuable under the warrant in September 2003.

      In September  2003,  the Company  issued  20,000 shares of common stock to
Fusion  Capital Fund II, LLC  ("Fusion")  as  compensation  for expected  future
capital  raising  activities.  The Company also  entered into an agreement  with
Fusion under which Fusion would provide an Equity Line of Credit  subject to the
Company filing a Registration Statement. The agreement also required the Company
to issue  200,000  shares of the  Company's  common  stock to Fusion,  as a fee,
subject to a holding  period before Fusion can sell the shares.  As the issuance
represented a  transaction  by an issuer (i.e. -- the Company) not involving any
public  offering,  the shares  were  issued  pursuant  to the  private  offering
exemption set forth in Section 4(2) of the Act.

      During  October 2003 through  December  2003,  the Company  issued 327,698
shares of its common stock  pursuant to the exercise of warrants.  There were no
underwriters  involved  in the  sales,  which  were to four  purchasers  who are
suitable,  sophisticated  non-U.S.  residents.  The shares were sold for cash at
prices  ranging from $2.00 to $3.00 per share at an aggregate  offering price of
$699,000.  As the issuance  represented a transaction  by an issuer (i.e. -- the
Company) not involving any public  offering,  the shares were issued pursuant to
the private offering  exemption set forth in Section 4(2) of the Act.  Aggregate
offering expenses were nominal.

      During  January 2004 through June 2004,  the Company issued 602,000 shares
of its common  stock  pursuant to the  exercise of warrants  and 103,750  shares
pursuant to the exercise of options.  There were no underwriters involved in the
sales, which were to six purchasers who are suitable,  sophisticated  investors,
five of which are non-U.S.  residents. As the issuance represented a transaction
by an issuer (i.e. -- the Company) not involving any public offering, the shares
were issued pursuant to the private offering exemption set forth in Section 4(2)
of the Act. The shares were sold for cash at prices  ranging from $1.50 to $3.00
per share at an  aggregate  offering  price of  $1,970,932.  Aggregate  offering
expenses were nominal.


                                      II-8


      During August of 2004, the Company entered into a financing transaction in
which it: (i) issued 22,000 shares of Series A  Convertible  Preferred  Stock in

(7%) royalty  agreement in exchange for Warrants to acquire up to 400,000 shares
of the Company's Common Stock at a price of $1.75 per share. The Warrants expire

issued pursuant to the private  offering  exemption set forth in Section 4(2) of
the Act.

ITEM 28. UNDERTAKINGS

The undersigned registrant hereby undertakes:

(1)   To file,  during  any  period in which it offers  or sells  securities,  a
      post-effective amendment to this registration statement to:

      (i)   Include any prospectus required by Sections 10(a)(3) of the Act;

      (ii)  To reflect in the  prospectus  any facts or events arising after the
            effective  date of the  Registration  Statement  (or the most recent
            post-effective  amendment  thereof)  which,  individually  or in the
            aggregate,  represent a fundamental  change in the  information  set
            forth in the Registration Statement.  Notwithstanding the foregoing,
            any  increase or decrease  in volume of  securities  offered (if the
            total dollar value of securities offered would not exceed that which
            was  registered)  and any deviation  from the low or high end of the
            estimated  maximum  offering  range may be  reflected in the form of
            prospectus filed with the Commission  pursuant to Rule 424(b) if, in
            the  aggregate,  the changes in volume and price  represent  no more
            than 20 percent change in the maximum  aggregate  offering price set
            forth  in  the  "Calculation  of  Registration  Fee"  table  in  the
            effective registration statement;


                                     II-16


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

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

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

(4)   Insofar as  indemnification  for liabilities  arising under the Securities
      Act may be permitted to directors, officers and controlling persons of the
      small business issuer pursuant to the foregoing provisions,  or otherwise,
      the small  business  issuer has been  advised  that in the  opinion of the
      Securities and Exchange Commission such  indemnification is against public
      policy  as   expressed   in  the   Securities   Act  and  is,   therefore,
      unenforceable.  In the event that a claim for indemnification against such
      liabilities  (other  than the  payment  by the  small  business  issuer of
      expenses incurred or paid by a director,  officer or controlling person of
      the small business issuer 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 small business issuer
      will,  unless in the opinion of its counsel the matter has been settled by
      controlling precedent,  submit to a court of appropriate  jurisdiction the
      question  whether such  indemnification  by it is against public policy as
      expressed  in the  Securities  Act  and  will  be  governed  by the  final
      adjudication of such issue.


                                     II-17
