OF

INVISA, INC.

This prospectus relates to the public offering of up to 6,225,000 shares of our common stock, par value $0.001 per share, for sale by certain of our stockholders identified in this prospectus for their own accounts. Such stockholders are referred to throughout this prospectus as "selling stockholders." These shares include 1,662,500 shares of outstanding common stock, up to 2,900,000 shares of common stock issuable upon conversion of preferred stock and 1,662,500 shares of common stock issuable upon the exercise of warrants. We will pay the expenses of registering these shares.

Our common stock is quoted on the Over-the-Counter Bulletin Board under the symbol "INSA." On September 20, 2004 the closing sales price for the common stock on the OTCBB was $0.53 per share.

In this prospectus and any amendment or supplement hereto, unless otherwise indicated, the terms "Invisa", the "Company", "we", "us", and "our" refer and relate to Invisa, Inc.

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.

Common Stock Offered                Up to  6,225,000  shares  of  common  stock,
                                    including  u  p  to   1,662,500   shares  of
                                    outstanding  common  stock,  up to 2,900,000

                                    conversion  of the Series A Preferred  Stock
                                    and   1,662,500   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

                                    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 September 20, 2004, there were 21,335,832 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 September 20, 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 14,500 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 $1,662,500. 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 September 20, 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.

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.

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.

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.

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.

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 was paid on September 14, 2004.

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.

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.

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.

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.

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.

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.

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.

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

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.

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).

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

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

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 opinion of management, are necessary for a fair presentation and are prepared on the same basis as the audited annual statements.

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).

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 share because the effect would be anti-dilutive.

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

NOTE L - COMMON STOCK - Continued

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

NOTE L - COMMON STOCK - Continued

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.

The Company received cash proceeds of $700,503, net of transaction costs related to this unit offering. The warrants are exercisable until Jun 30, 2005.

NOTE M - STOCK OPTIONS - Continued

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.

Any warrants not timely exercised or redeemed automatically expire on August 15, 2004.

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.

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.

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.

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.

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.

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.

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.

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.

Invisa, Inc.
4400 Independence Court
Sarasota, FL 34234

Re: Invisa, Inc.

Ladies and Gentlemen:

We have acted as counsel for Invisa, Inc., a Nevada corporation (the "Company"), in connection with the preparation of its Registration Statement on Form SB-2 (the "Registration Statement") to which this opinion is an exhibit, to be filed with the Securities and Exchange Commission on or about September 22, 2004.

It is our opinion that the shares of common stock, par value $0.001 per share, being registered, when sold in the manner and for the consideration contemplated by the Registration Statement, will be validly issued, fully paid and non-assessable.

We consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the heading "Legal Matters."

Very truly yours,

/s/ Ellenoff Grossman & Schole LLP

Ellenoff Grossman & Schole LLP


CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We have issued our report dated April 9, 2004, accompanying the consolidated balance sheets of Invisa, Inc. as of December 31, 2002 and 2003 and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the years then ended contained in the Registration Statement and Prospectus, which report contains an explanatory paragraph relating to certain significant risks and uncertainties which conditions raise substantial doubt about the Company's ability to continue as a going concern. We consent to the use of the aforementioned report in the Registration Statement and Prospectus, and to the use of our name as it appears under the caption "Experts".
