Ladies and Gentlemen:

Invisa, Inc., a Nevada corporation (the "COMPANY"), hereby confirms its agreement with Mercator Momentum Fund, LP, and Monarch Pointe Fund, Ltd. (collectively, the "PURCHASERS") and Mercator Advisory Group, LLC ("MAG"), as set forth below.

1. The Securities. Subject to the terms and conditions herein contained, the Company proposes to issue and sell to the Purchasers an aggregate of Twenty-Two Thousand (22,000) shares of its Series A Convertible Preferred Stock (the "SERIES A STOCK"), which shall be convertible into shares (the "CONVERSION SHARES") of the Company's Common Stock (the "COMMON STOCK") in accordance with the formula set forth in the Certificate of Designations further described below and to Purchasers and MAG for no additional compensation an aggregate of One Million Five Hundred Thousand (1,500,000) warrants, substantially in the form attached hereto at Exhibit A (the "WARRANTS"), to acquire up to One Million Five Hundred Thousand (1,500,000) shares of Common Stock (the "WARRANT SHARES"). The rights, preferences and privileges of the Series A Stock are as set forth in the Certificate of Designations of Series A Preferred Stock as filed with the Secretary of State of the State of Nevada (the "CERTIFICATE OF DESIGNATIONS") in the form attached hereto as Exhibit B. The number of Conversion Shares and Warrant Shares that any Purchaser may acquire at any time are subject to limitation in the Certificate of Designations and in the Warrants, respectively, so that the aggregate number of shares of Common Stock of which such Purchaser and all persons affiliated with such Purchaser have beneficial ownership (calculated pursuant to Rule 13d-3 of the Securities Exchange Act of 1934, as amended) does not at any time exceed 9.99% of the Company's then outstanding Common Stock.

The Series A Stock and the Warrants are sometimes herein collectively referred to as the "SECURITIES." This Agreement, the Warrants and the Certificate of Designations are sometimes herein collectively referred to as the "TRANSACTION DOCUMENTS."

The Securities will be offered and sold to the Purchasers without such offers and sales being registered under the Securities Act of 1933, as amended (together with the rules and regulations of the Securities and Exchange Commission (the "SEC") promulgated thereunder, the "SECURITIES ACT"), in reliance on exemptions therefrom.

In connection with the sale of the Securities, the Company has made available (including electronically via the SEC's EDGAR system) to Purchasers and the Purchasers have reviewed its periodic and current reports, forms, schedules, proxy statements and other documents (including exhibits and all other information incorporated by reference) filed with the SEC under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"). These reports, forms, schedules, statements, documents, filings and amendments, are collectively referred to as the "DISCLOSURE DOCUMENTS." All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Disclosure Documents (or other references of like import) shall be deemed to mean and include all such financial statements and schedules, documents, exhibits and other information which is incorporated by reference in the Disclosure Documents.

2. Representations and Warranties of the Company.

The Disclosure Documents and the documents incorporated or deemed to be incorporated by reference therein, at the time they were filed or hereafter are filed with the SEC, complied and will comply, at the time of filing, in all material respects with the requirements of the Securities Act and/or the Exchange Act, as the case may be, as applicable.

6. Representations and Warranties of the Purchasers.

(a) Each Purchaser and MAG represents and warrants to the Company that the Securities to be acquired by it hereunder (including the Conversion Shares and the Warrant Shares that it may acquire upon conversion or exercise thereof, as the case may be) are being acquired for its own account for investment and with no intention of distributing or reselling such Securities (including the Conversion Shares and the Warrant Shares that it may acquire upon conversion or exercise thereof, as the case may be) or any part thereof or interest therein in any transaction which would be in violation of the securities laws of the United States of America or any State. Nothing in this Agreement, however, shall prejudice or otherwise limit a Purchaser's right to sell or otherwise dispose of all or any part of such Conversion Shares or Warrant Shares under an effective registration statement under the Securities Act and in compliance with applicable state securities laws or under an exemption from such registration. By executing this Agreement, each Purchaser further represents that such Purchaser does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participation to any Person with respect to any of the Securities.

(b) Each Purchaser and MAG understands that the Securities (including the Conversion Shares and the Warrant Shares that it may acquire upon conversion or exercise thereof, as the case may be) have not been registered under the Securities Act and may not be offered, resold, pledged or otherwise transferred except (a) pursuant to an exemption from registration under the Securities Act (and, if requested by the Company, based upon an opinion of counsel acceptable to the Company) or pursuant to an effective registration statement under the Securities Act and (b) in accordance with all applicable securities laws of the states of the United States and other jurisdictions.

Each Purchaser and MAG agrees to the imprinting, so long as appropriate, of the following legend on the Securities (including the Conversion Shares and the Warrant Shares that it may acquire upon conversion or exercise thereof, as the case may be):

THE SHARES OF STOCK EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ("TRANSFERRED") IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. IN THE ABSENCE OF SUCH REGISTRATION, SUCH SHARES MAY NOT BE TRANSFERRED UNLESS, IF THE COMPANY REQUESTS, THE COMPANY HAS RECEIVED A WRITTEN OPINION FROM COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY STATING THAT SUCH TRANSFER IS BEING MADE IN COMPLIANCE WITH ALL APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

The legend set forth above may be removed if and when the Conversion Shares or the Warrant Shares, as the case may be, are disposed of pursuant to an effective registration statement under the Securities Act or in the opinion of counsel to the Company experienced in the area of United States Federal securities laws such legends are no longer required under applicable requirements of the Securities Act. The Series A Stock, the Warrants, the Conversion Shares and the Warrant Shares shall also bear any other legends required by applicable Federal or state securities laws, which legends may be removed when in the opinion of counsel to the Company experienced in the applicable securities laws, the same are no longer required under the applicable requirements of such securities laws. The Company agrees that it will provide each Purchaser, upon request, with a substitute certificate, not bearing such legend at such time as such legend is no longer applicable. Each Purchaser

agrees that, in connection with any transfer of the Conversion Shares or the Warrant Shares by it pursuant to an effective registration statement under the Securities Act, such Purchaser will comply with all prospectus delivery requirements of the Securities Act. The Company makes no representation, warranty or agreement as to the availability of any exemption from registration under the Securities Act with respect to any resale of the Series A Stock, the Warrants, the Conversion Shares or the Warrant Shares. (c) Each Purchaser and MAG is an "accredited investor" within the meaning of Rule 501(a) of Regulation D under the Securities Act. Neither Purchaser nor MAG learned of the opportunity to acquire Securities or any other security issuable by the Company through any form of general advertising or public solicitation.

(d) Each Purchaser and MAG represents and warrants to the Company that it has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, having been represented by counsel, and has so evaluated the merits and risks of such investment and is able to bear the economic risk of such investment and, at the present time, is able to afford a complete loss of such investment.

(e) Each Purchaser represents and warrants to the Company that
(i) the purchase of the Securities to be purchased by it has been duly and properly authorized and this Agreement has been duly executed and delivered by it or on its behalf and constitutes the valid and legally binding obligation of the Purchaser, enforceable against the Purchaser in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights generally and to general principles of equity; (ii) the purchase of the Securities to be purchased by it does not conflict with or violate its charter, by-laws or any law, regulation or court order applicable to it; and (iii) the purchase of the Securities to be purchased by it does not impose any penalty or other onerous condition on the Purchaser under or pursuant to any applicable law or governmental regulation.

(f) Each Purchaser and MAG represents and warrants to the Company that neither it nor any of its directors, officers, employees, agents, partners, members, or controlling persons has taken, or will take, directly or indirectly, any actions designed, or might reasonably be expected to cause or result in the stabilization or manipulation of the price of the Common Stock.

(g) Each Purchaser and MAG acknowledges it or its representatives have reviewed the Disclosure Documents and further acknowledges that it or its representatives have been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and the Company's financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment in the Securities; and (iii) the opportunity to obtain such additional information which the

(i) Each Purchaser and MAG understands and acknowledges that

8. Termination.

(a) This Agreement may be terminated in the sole discretion of the Company by notice to each Purchaser if at the Closing Date:

(i) the representations and warranties made by any Purchaser in Section 6 are not true and correct in all material respects; or

(ii) as to the Company, the sale of the Securities hereunder (i) is prohibited or enjoined by any applicable law or governmental regulation or (ii) subjects the Company to any penalty, or in its reasonable judgment, other onerous condition under or pursuant to any applicable law or government regulation that would materially reduce the benefits to the Company of the sale of the Securities to such Purchaser, so long as such regulation, law or onerous condition was not in effect in such form at the date of this Agreement.

(b) This Agreement may be terminated by any Purchaser or MAG by notice to the Company given in the event that the Company shall have failed, refused or been unable to satisfy all material conditions on its part to be performed or satisfied hereunder on or prior to the Closing Date, or if after the execution and delivery of this Agreement and immediately prior to the Closing Date, trading in securities of the Company on the OTC BB shall have been suspended.

(c) This Agreement may be terminated by mutual written consent of all parties.

9. Registration. Within 30 days after the Closing Date, the Company shall prepare and file with the SEC a Registration Statement covering the resale of the maximum number of Conversion Shares issuable upon conversion of the Series A Stock and the Warrant Shares (collectively, the "REGISTRABLE SECURITIES"), as set forth in the Registration Rights Agreement attached hereto as Exhibit D. Within 120 days after the Closing Date , such Registration Statement must be declared effective by the SEC.

10. Event of Default. If an Event of Default (as defined below) occurs and remains uncured for a period of 5 days, the Purchasers and MAG shall have the right to exercise any or all of the rights given to the Purchasers and MAG relating to the Securities, as further described in the Certificate of Designations. In addition, the price at which the shares of Series A Stock may be converted into Common Stock shall be reduced from 80% of the Market Price (as defined in the Certificate of Designations) to 70% of the Market Price, subject to the Ceiling Price and Floor Price as those terms are defined in the Certificate of Designations.

The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Holder at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

An "EVENT OF DEFAULT" shall include the commencement by the Company of a voluntary case or proceeding under the bankruptcy laws or the Company's failure to: (i) discharge or stay a bankruptcy proceeding within 60 days of such action being taken against the Company, (ii) file the Registration Statement with the SEC within 30 days after the Closing Date, (iii) have the Registration Statement deemed effective by the SEC within 120 days after the Closing Date;

IN THE EVENT THAT THE COMPANY FAILS TO FILE THE REGISTRATION STATEMENT WITH THE SEC WITHIN 30 DAYS AFTER THE CLOSING DATE, AS A REMEDY FOR SUCH AN EVENT OF

DEFAULT, COMPANY SHALL PAY TO PURCHASERS, IN CASH, ONE THOUSAND FOUR HUNDRED SIXTY-SIX DOLLARS ($1,466) FOR EACH DAY THAT THE REGISTRATION STATEMENT FILING IS DELAYED. PURCHASERS AND COMPANY ACKNOWLEDGE AND AGREE THAT THEY HAVE MUTUALLY DISCUSSED THE IMPRACTICALITY AND EXTREME DIFFICULTY OF FIXING THE ACTUAL DAMAGES PURCHASERS WOULD INCUR IN THE CASE OF SUCH AN EVENT OF DEFAULT, AND THAT AS A RESULT OF SUCH DISCUSSION THE PARTIES AGREE THAT $1,466 FOR EACH DAY THAT THE REGISTRATION STATEMENT FILING IS DELAYED REPRESENTS A REASONABLE ESTIMATE OF THE ACTUAL DAMAGES WHICH PURCHASERS WOULD INCUR IN THE CASE OF SUCH AN EVENT OF DEFAULT. BY SIGNING IN THE SPACES WHICH FOLLOW, PURCHASERS AND COMPANY SPECIFICALLY AND EXPRESSLY AGREE TO ABIDE BY THE TERMS AND PROVISIONS OF THIS PARAGRAPH CONCERNING LIQUIDATED DAMAGES.

EXHIBIT 10.93

REGISTRATION RIGHTS AGREEMENT

AGREEMENT dated as of August 16, 2004, between MERCATOR MOMENTUM FUND, L.P., MONARCH POINTE FUND, LTD. (collectively, the "Funds") and MERCATOR ADVISORY GROUP, LLC ("MAG") (the Funds and MAG are referred to individually as a "Holder" and collectively as the "Holders"), and Invisa a Nevada corporation (the "Company").

WHEREAS, the Funds have purchased, for an aggregate of $2,200,000 an aggregate of 22,000 shares of Series A Convertible Preferred Stock (the "Series A Stock") from the Company, and have the right to cause their Series A Stock to be converted into shares of Common Stock, $.001 par value (the "Common Stock"), of the Company, pursuant to the conversion formula set forth in the Certificate of Designations;

WHEREAS, each Fund and MAG have acquired Warrants (together, the "Warrants") from the Company, pursuant to which the Holders have the right to purchase in the aggregate up to 1,500,000 shares of the Common Stock through the exercise of the Warrants;

WHEREAS, the Company desires to grant to the Holders the registration rights set forth herein with respect to the shares of Common Stock issuable upon the conversion of the Series A Stock and the exercise of the Warrants.

NOW, THEREFORE, the parties hereto mutually agree as follows:

1. REGISTRABLE SECURITIES. As used herein the terms "Registrable Security" means each of the shares of Common Stock (i) issued upon the conversion of the Series A Stock (the "Conversion Shares") or (ii) upon exercise of the Warrants (the "Warrant Shares"), provided, however, that with respect to any particular Registrable Security, such security shall cease to be a Registrable Security when, as of the date of determination that (a) it has been effectively registered under the Securities Act of 1933, as amended (the "Securities Act"), and disposed of pursuant thereto, or (b) registration under the Securities Act is no longer required for the immediate public distribution of such security. The term "Registrable Securities" means any and/or all of the securities falling within the foregoing definition of a "Registrable Security." In the event of any merger, reorganization, consolidation, recapitalization or other change in corporate structure affecting the Common Stock, such adjustment shall be made in the definition of "Registrable Security" as is appropriate in order to prevent any dilution or enlargement of the rights granted pursuant to this Section 1.

2. REGISTRATION.

(a) The Company shall file a registration statement (the "Registration Statement") with the Securities and Exchange Commission (the "SEC") within thirty (30) days after the date of this Agreement in order to register the resale of the Registrable Securities under the Securities Act. Once effective, the Company shall maintain the effectiveness of the Registration Statement until the earlier of (i) the date that all of the Registrable Securities have been sold, or (ii) the date that the Company receives an opinion of counsel to the Company that all of the Registrable Securities may be freely

traded without registration under the Securities Act, under Rule 144 promulgated under the Securities Act or otherwise.

(b) The Company will initially include in the Registration Statement as Registrable Securities Five Million Nine Hundred Thousand (5,900,000) shares of Common Stock.

3. COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.

The Company covenants and agrees as follows:

(a) The Company shall use best efforts to cause the Registration Statement to become effective with the SEC as promptly as possible and in no event more than 120 days after the date of this Agreement. If any stop order shall be issued by the SEC in connection therewith, the Company shall use best efforts to obtain promptly the removal of such order. Following the effective date of the Registration Statement, the Company shall, upon the request of any Holder, forthwith supply such reasonable number of copies of the Registration Statement, preliminary prospectus and prospectus meeting the requirements of the Securities Act, and any other documents necessary or incidental to the public offering of the Registrable Securities, as shall be reasonably requested by the Holder to permit the Holder to make a public distribution of the Holder's Registrable Securities. The obligations of the Company hereunder with respect to the Holder's Registrable Securities are subject to the Holder's furnishing to the Company such appropriate information concerning the Holder, the Holder's Registrable Securities and the terms of the Holder's offering of such Registrable Securities as the Company may reasonably request in writing.

(b) The Company shall pay all costs, fees and expenses in connection with the Registration Statement filed pursuant to Section 2 hereof including, without limitation, the Company's legal and accounting fees, printing expenses, and blue sky fees and expenses; provided, however, that each Holder shall be solely responsible for the fees of any counsel retained by the Holder in connection with such registration and any transfer taxes or underwriting discounts, commissions or fees applicable to the Registrable Securities sold by the Holder pursuant thereto.

(c) The Company will take all actions which may be required to qualify or register the Registrable Securities included in the Registration Statement for the offer and sale under the securities or blue sky laws of such states as are reasonably requested by each Holder of such securities, provided that the Company shall not be obligated to execute or file any general consent to service of process or to qualify as a foreign corporation to do business under the laws of any such jurisdiction.

4. ADDITIONAL TERMS.

(a) The Company shall indemnify and hold harmless the Holders and each underwriter, within the meaning of the Securities Act, who may purchase from or sell for any Holder, any Registrable Securities, from and against any and all losses, claims, damages and liabilities caused by any untrue statement of a material fact contained in the Registration Statement, any other registration statement filed by the Company under the Securities Act with

respect to the registration of the Registrable Securities, any post-effective amendment to such registration statements, or any prospectus included therein or caused by any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission based upon information furnished or required to be furnished in writing to the Company by the Holders or underwriter expressly for use therein, which indemnification shall include each person, if any, who controls any Holder or underwriter within the meaning of the Securities Act and each officer, director, employee and agent of each Holder and underwriter; provided, however, that the indemnification in this Section 4(a) with respect to any prospectus shall not inure to the benefit of any Holder or underwriter (or to the benefit of any person controlling any Holder or underwriter) on account of any such loss, claim, damage or liability arising from the sale of Registrable Securities by the Holder or underwriter, if a copy of a subsequent prospectus correcting the untrue statement or omission in such earlier prospectus was provided to such Holder or underwriter by the Company prior to the subject sale and the subsequent prospectus was not delivered or sent by the Holder or underwriter to the purchaser prior to such sale and provided further, that the Company shall not be obligated to so indemnify any Holder or any such underwriter or other person referred to above unless the Holder or underwriter or other person, as the case may be, shall at the same time indemnify the Company, its directors, each officer signing the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any and all losses, claims, damages and liabilities caused by any untrue statement of a material fact contained in the Registration Statement, any registration statement or any prospectus required to be filed or furnished by reason of this Agreement or caused by any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission based upon information furnished in writing to the Company by the Holder or underwriter expressly for use therein.

(b) If for any reason the indemnification provided for in the preceding section is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations.

(c) Neither the filing of a Registration Statement by the Company pursuant to this Agreement nor the making of any request for prospectuses by the Holder shall impose upon any Holder any obligation to sell the Holder's Registrable Securities.

(d) Each Holder, upon receipt of notice from the Company that an event has occurred which requires a Post-Effective Amendment to the Registration Statement or a supplement to the prospectus included therein, shall promptly discontinue the sale of Registrable Securities until the Holder receives a copy of a supplemented or amended prospectus from the Company, which the Company shall provide as soon as practicable after such notice.

(e) If the Company fails to keep the Registration Statement referred to above continuously effective during the requisite period, then the Company shall, promptly upon the request of any Holder, use best efforts to update the Registration Statement or file a new registration statement covering the Registrable Securities remaining unsold, subject to the terms and provisions hereof.

(f) Each Holder agrees to provide the Company with any information or undertakings reasonably requested by the Company in order for the Company to include any appropriate information concerning the Holder in the Registration Statement or in order to promote compliance by the Company or the Holder with the Securities Act.

(g) The Company agrees that it shall cause each of its shareholders owning ten percent (10%) or more of the Company's outstanding Common Stock to refrain from selling any shares of the Company's Common Stock until the Registration Statement has been declared effective The Company agrees that it shall cause each of its directors and officers to execute a lock-up agreement providing that (i) for a period of 6 months after the date hereof, such officers and directors shall not sell in the aggregate more than 20,000 shares of Common Stock during any 30 day period, and (ii) for months 7 through 12 after the date hereof, they shall not individually sell more than 20,000 shares of Common Stock during any 30 day period.

(h) Each Holder, on behalf of itself and its affiliates, hereby covenants and agrees not to, directly or indirectly, offer to "short sell", contract to "short sell" or otherwise "short sell" any securities of the Company, including, without limitation, shares of Common Stock that will be received as a result of the conversion of the Series A Stock or the exercise of the Warrants.

5. GOVERNING LAW. The Registrable Securities will be, if and when issued, delivered in California. This Agreement shall be deemed to have been made and delivered in the State of California and shall be governed as to validity, interpretation, construction, effect and in all other respects by the internal substantive laws of the State of California, without giving effect to the choice of law rules thereof.

6. AMENDMENT. This Agreement may only be amended by a written instrument executed by the Company and the Holders.

7. ENTIRE AGREEMENT. This Agreement constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all prior agreements and understandings of the parties, oral and written, with respect to the subject matter hereof.

8. EXECUTION IN COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same document.

THIS WARRANT CERTIFIES THAT for value received, Mercator Momentum Fund, LP., or its registered assigns (hereinafter called the "HOLDER") is entitled to purchase from Invisa, Inc. (hereinafter called the "COMPANY"), the above referenced number of fully paid and nonassessable shares (the "SHARES") of common stock (the "COMMON STOCK"), of Company, at the Warrant Price per Share referenced above; the number of shares purchasable upon exercise of this Warrant referenced above being subject to adjustment from time to time as described herein. This Warrant is issued in connection with that certain Subscription Agreement dated as of August 16, 2004, by and between the Company and Holder (the "SUBSCRIPTION AGREEMENT"). The exercise of this Warrant shall be subject to the provisions, limitations and restrictions contained herein.

Term and Exercise.

1.1 TERM. This Warrant is exercisable in whole or in part (but not as to any fractional share of Common Stock), at any time and from time to time after the date hereof prior to 6:00 p.m. on the Expiration Date set forth above.

1.2 WARRANT PRICE. The Warrant shall be exercisable at the Warrant Price described above.

1.3 MAXIMUM NUMBER OF SHARES. The maximum number of Shares of Common Stock exercisable pursuant to this Warrant is 250,568 Shares. However, notwithstanding anything herein to the contrary, in no event shall the Holder be permitted to exercise this Warrant for a number of Shares greater than the number that would cause the aggregate beneficial ownership of the Company's Common Stock (calculated pursuant to Rule 13d-3 of the Securities Exchange Act of 1934, as amended) of the Holder and all persons affiliated with the Holder to equal 9.99% of the Company's Common Stock then outstanding.

1.4 PROCEDURE FOR EXERCISE OF WARRANT. Holder may exercise this Warrant by delivering the following to the principal office of the Company in accordance with Section 5.1 hereof: (i) a duly executed Notice of Exercise in substantially the form attached as Schedule A, (ii) payment of the Warrant Price then in effect for each of the Shares being purchased, as designated in the Notice of Exercise, and (iii) this Warrant. Payment of the Warrant Price may be in cash, certified or official bank check payable to the order of the Company, or wire transfer of funds to the Company's account (or any combination of any of the foregoing) in the amount of the Warrant Price for each share being purchased.

1.5 DELIVERY OF CERTIFICATE AND NEW WARRANT. In the event of any exercise of the rights represented by this Warrant, a certificate or certificates for the shares of Common Stock so purchased, registered in the name of the Holder or such other name or names as may be designated by the Holder, together with any other securities or other property which the Holder is entitled to receive upon exercise of this Warrant, shall be delivered to the Holder hereof, at the Company's expense, within a reasonable time, not exceeding fifteen (15) calendar days, after the rights represented by this Warrant shall have been so exercised; and, unless this Warrant has expired, a new Warrant representing the number of Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder hereof within such time. The person in whose name any certificate for shares of Common Stock is issued upon exercise of this Warrant shall for all purposes be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was received by the Company, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and payment is on a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such Shares at the close of business on the next succeeding date on which the stock transfer books are open.

1.6 RESTRICTIVE LEGEND. Each certificate for Shares shall bear a restrictive legend in substantially the form as follows, together with any additional legend required by (i) any applicable state securities laws and (ii) any securities exchange upon which such Shares may, at the time of such exercise, be listed:

THE SHARES OF STOCK EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ("TRANSFERRED") IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. IN THE ABSENCE OF SUCH REGISTRATION, SUCH SHARES MAY NOT BE TRANSFERRED UNLESS, IF THE COMPANY REQUESTS, THE COMPANY HAS RECEIVED A WRITTEN OPINION FROM COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY STATING THAT SUCH TRANSFER IS BEING MADE IN COMPLIANCE WITH ALL APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

Any certificate issued at any time in exchange or substitution for any certificate bearing such legend shall also bear such legend unless, in the opinion of counsel for the Holder thereof (which counsel shall be reasonably satisfactory to the Company), the securities represented thereby are not, at such time, required by law to bear such legend.

1.7 FRACTIONAL SHARES. No fractional Shares shall be issuable upon exercise or conversion of the Warrant. In the event of a fractional interest, the number of Shares to be issued shall be rounded up to the nearest whole Share.

Representations, Warranties and Covenants.

1.8 REPRESENTATIONS AND WARRANTIES.

(a) The Company is a corporation duly organized, validly existing and in good standing under the laws of its state of incorporation and has all necessary power and authority to perform its obligations under this Warrant;

(b) The execution, delivery and performance of this Warrant has been duly authorized by all necessary actions on the part of the Company and constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms; and

(c) This Warrant does not violate and is not in conflict with any of the provisions of the Company's Articles of Incorporation or Certificate of Determination, Bylaws and any resolutions of the Company's Board of Directors or stockholders, or any agreement of the Company, and no event has occurred and no condition or circumstance exists that might (with or without notice or lapse of time) constitute or result directly or indirectly in such a violation or conflict.

1.9 ISSUANCE OF SHARES. The Company covenants and agrees that all shares of Common Stock that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issue thereof. The Company further covenants and agrees that it will pay when due and payable any and all federal and state taxes which may be payable in respect of the issue of this Warrant or any Common Stock or certificates therefor issuable upon the exercise of this Warrant. The Company further covenants and agrees that the Company will at all times have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise in full of the rights represented by this Warrant. If at any time the number of authorized but unissued shares of Common Stock of the Company shall not be sufficient to effect the exercise of the Warrant in full, subject to the limitations set forth in Section 1.3 hereto, then the Company will take all such corporate action as may, in the opinion of counsel to the Company, be necessary or advisable to increase the number of its authorized shares of Common Stock as shall be sufficient to permit the exercise of the Warrant in full, subject to the limitations set forth in Section 1.3 hereto, including without limitation, using its best efforts to obtain any necessary stockholder approval of such increase. The Company further covenants and agrees that if any shares of capital stock to be reserved for the purpose of the issuance of shares upon the exercise of this Warrant require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued or delivered upon exercise, then the Company will in good faith and as expeditiously as possible endeavor to secure such registration or approval, as the case may be. If and so long as the Common Stock issuable upon the exercise of this Warrant is listed on any national securities exchange or the Nasdaq Stock Market, the Company will, if permitted by the rules of such exchange or market, list and keep listed on such exchange or market, upon official notice of issuance, all shares of such Common Stock issuable upon exercise of this Warrant.

Other Adjustments.

1.10 SUBDIVISION OR COMBINATION OF SHARES. In case the Company shall at any time subdivide its outstanding Common Stock into a greater number of shares, the Warrant Price in effect immediately prior to such subdivision shall be proportionately reduced, and the number of Shares subject to this Warrant shall be proportionately increased, and conversely, in case the outstanding Common Stock of the Company shall be combined into a smaller number of shares, the Warrant Price in effect immediately prior to such combination shall be proportionately increased, and the number of Shares subject to this Warrant shall be proportionately decreased.

1.11 DIVIDENDS IN COMMON STOCK, OTHER STOCK OR PROPERTY. If at any time or from time to time the holders of majority in interest of the Common Stock (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received or become entitled to receive, without payment therefor:

(a) Common Stock, Options or any shares or other securities which are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution;

(b) any cash paid or payable otherwise than as a regular cash dividend; or

(c) Common Stock or additional shares or other securities or property (including cash) by way of spin-off, split-up, reclassification, combination of shares or similar corporate rearrangement (other than Common Stock issued as a stock split or adjustments in respect of which shall be covered by the terms of
Section 3.1 above) and additional shares, other securities or property issued in connection with a Change (as defined below) (which shall be covered by the terms of Section 3.4 below), then and in each such case, the Holder hereof shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to in clause (b) above and this clause (c)) which such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property.

1.12 REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE. If any recapitalization, reclassification or reorganization of the share capital of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its shares and/or assets or other transaction (including, without limitation, a sale of substantially all of its assets followed by a liquidation) shall be effected in such a way that holders of Common Stock shall be entitled to receive shares, securities or other assets or property (a "Change"), then, as a condition of such Change, lawful and adequate provisions shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares, securities or other assets or property as may be issued or payable with respect to or in exchange for the number of outstanding Common Stock which such Holder would have been entitled to receive had such Holder exercised this Warrant immediately prior to the consummation of such Change. The Company or its successor shall promptly issue to Holder a new Warrant for such new securities or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to give effect to the adjustments provided for in this Section 3 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Section 3.3 shall similarly apply to successive Changes.

Ownership and Transfer.

1.13 OWNERSHIP OF THIS WARRANT. The Company may deem and treat the person in whose name this Warrant is registered as the holder and owner hereof (notwithstanding any notations of ownership or writing hereon made by anyone other than the Company) for all purposes and shall not be affected by any notice to the contrary until presentation of this Warrant for registration of transfer as provided in this Section 4.

1.14 TRANSFER AND REPLACEMENT. This Warrant and all rights hereunder are transferable in whole or in part upon the books of the Company by the Holder hereof in person or by duly authorized attorney, and a new Warrant or Warrants, of the same tenor as this Warrant but registered in the name of the transferee or transferees (and in the name of the Holder, if a partial transfer is

effected) shall be made and delivered by the Company upon surrender of this Warrant duly endorsed, at the office of the Company in accordance with Section 5.1 hereof. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft or destruction, and, in such case, of indemnity or security reasonably satisfactory to it, and upon surrender of this Warrant if mutilated, the Company will make and deliver a new Warrant of like tenor, in lieu of this Warrant; provided that if the Holder hereof is an instrumentality of a state or local government or an institutional holder or a nominee for such an instrumentality or institutional holder an irrevocable agreement of indemnity by such Holder shall be sufficient for all purposes of this Warrant, and no evidence of loss or theft or destruction shall be necessary. This Warrant shall be promptly cancelled by the Company upon the surrender hereof in connection with any transfer or replacement. Except as otherwise provided above, in the case of the loss, theft or destruction of a Warrant, the Company shall pay all expenses, taxes and other charges payable in connection with any transfer or replacement of this Warrant, other than income taxes and stock transfer taxes (if any) payable in connection with a transfer of this Warrant, which shall be payable by the Holder. Holder will not transfer this Warrant and the rights hereunder except in compliance with federal and state securities laws and except after providing evidence of such compliance reasonably satisfactory to the Company.

The Company further covenants and agrees that it will pay when due and payable any and all federal and state taxes which may be payable in respect of the issue of this Warrant or any Common Stock or certificates therefor issuable upon the exercise of this Warrant. The Company further covenants and agrees that the Company will at all times have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise in full of the rights represented by this Warrant. If at any time the number of authorized but unissued shares of Common Stock of the Company shall not be sufficient to effect the exercise of the Warrant in full, subject to the limitations set forth in Section 1.3 hereto, then the Company will take all such corporate action as may, in the opinion of counsel to the Company, be necessary or advisable to increase the number of its authorized shares of Common Stock as shall be sufficient to permit the exercise of the Warrant in full, subject to the limitations set forth in Section 1.3 hereto, including without limitation, using its best efforts to obtain any necessary stockholder approval of such increase. The Company further covenants and agrees that if any shares of capital stock to be reserved for the purpose of the issuance of shares upon the exercise of this Warrant require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued or delivered upon exercise, then the Company will in good faith and as expeditiously as possible endeavor to secure such registration or approval, as the case may be. If and so long as the Common Stock issuable upon the exercise of this Warrant is listed on any national securities exchange or the Nasdaq Stock Market, the Company will, if permitted by the rules of such exchange or market, list and keep listed on such exchange or market, upon official notice of issuance, all shares of such Common Stock issuable upon exercise of this Warrant.

3. OTHER ADJUSTMENTS.

3.1 SUBDIVISION OR COMBINATION OF SHARES. In case the Company shall at any time subdivide its outstanding Common Stock into a greater number of shares, the Warrant Price in effect immediately prior to such subdivision shall be proportionately reduced, and the number of Shares subject to this Warrant shall be proportionately increased, and conversely, in case the outstanding Common Stock of the Company shall be combined into a smaller number of shares, the Warrant Price in effect immediately prior to such combination shall be proportionately increased, and the number of Shares subject to this Warrant shall be proportionately decreased.

3.2 DIVIDENDS IN COMMON STOCK, OTHER STOCK OR PROPERTY.

(a) Common Stock, Options or any shares or other securities which are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution;

(b) any cash paid or payable otherwise than as a regular cash dividend; or

(c) Common Stock or additional shares or other securities or property (including cash) by way of spin-off, split-up, reclassification, combination of shares or similar corporate rearrangement (other than Common Stock issued as a stock split or adjustments in respect of which shall be covered by the terms of
Section 3.1 above) and additional shares, other securities or property issued in connection with a Change (as defined below) (which shall be covered by the terms of Section 3.4 below), then and in each such case, the Holder hereof shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to in clause (b) above and this clause (c)) which such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property.

3.3 REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE. If any recapitalization, reclassification or reorganization of the share capital of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its shares and/or assets or other transaction (including, without limitation, a sale of substantially all of its assets followed by a liquidation) shall be effected in such a way that holders of Common Stock shall be entitled to receive shares, securities or other assets or property (a "Change"), then, as a condition of such Change, lawful and adequate provisions shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares, securities or other assets or property as may be issued or payable with respect to or in exchange for the number of outstanding Common Stock which such Holder would have been entitled to receive had such Holder exercised this Warrant immediately prior to the consummation of such Change. The Company or its successor shall promptly issue to Holder a new Warrant for such new securities or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to give effect to the adjustments provided for in this Section 3 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Section 3.3 shall similarly apply to successive Changes.

Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft or destruction, and, in such case, of indemnity or security reasonably satisfactory to it, and upon surrender of this Warrant if mutilated, the Company will make and deliver a new Warrant of like tenor, in lieu of this Warrant; provided that if the Holder hereof is an instrumentality

of a state or local government or an institutional holder or a nominee for such an instrumentality or institutional holder an irrevocable agreement of indemnity by such Holder shall be sufficient for all purposes of this Warrant, and no evidence of loss or theft or destruction shall be necessary. This Warrant shall be promptly cancelled by the Company upon the surrender hereof in connection with any transfer or replacement. Except as otherwise provided above, in the case of the loss, theft or destruction of a Warrant, the Company shall pay all expenses, taxes and other charges payable in connection with any transfer or replacement of this Warrant, other than income taxes and stock transfer taxes (if any) payable in connection with a transfer of this Warrant, which shall be payable by the Holder.

This Warrant is issued in connection with that certain Subscription Agreement dated as of August 16, 2004, by and between the Company and Holder (the "SUBSCRIPTION AGREEMENT"). The exercise of this Warrant shall be subject to the provisions, limitations and restrictions contained herein.

1. TERM AND EXERCISE.

1.1 TERM. This Warrant is exercisable in whole or in part (but not as to any fractional share of Common Stock), at any time and from time to time after the date hereof prior to 6:00 p.m. on the Expiration Date set forth above.

1.2 WARRANT PRICE. The Warrant shall be exercisable at the Warrant Price described above.

1.3 MAXIMUM NUMBER OF SHARES. The maximum number of Shares of Common Stock exercisable pursuant to this Warrant is 499,432 Shares. However, notwithstanding anything herein to the contrary, in no event shall the Holder be permitted to exercise this Warrant for a number of Shares greater than the number that would cause the aggregate beneficial ownership of the Company's Common Stock (calculated pursuant to Rule 13d-3 of the Securities Exchange Act of 1934, as amended) of the Holder and all persons affiliated with the Holder to equal 9.99% of the Company's Common Stock then outstanding.

1.4 PROCEDURE FOR EXERCISE OF WARRANT. Holder may exercise this Warrant by delivering the following to the principal office of the Company in accordance with Section 5.1 hereof: (i) a duly executed Notice of Exercise in substantially the form attached as Schedule A, (ii) payment of the Warrant Price then in effect for each of the Shares being purchased, as designated in the Notice of Exercise, and (iii) this Warrant. Payment of the Warrant Price may be in cash, certified or official bank check payable to the order of the Company, or wire transfer of funds to the Company's account (or any combination of any of the foregoing) in the amount of the Warrant Price for each share being purchased.

1.5 DELIVERY OF CERTIFICATE AND NEW WARRANT. In the event of any exercise of the rights represented by this Warrant, a certificate or certificates for the shares of Common Stock so purchased, registered in the name of the Holder or such other name or names as may be designated by the Holder, together with any other securities or other property which the Holder is entitled to receive upon exercise of this Warrant, shall be delivered to the Holder hereof, at the Company's expense, within a reasonable time, not exceeding fifteen (15) calendar days, after the rights represented by this Warrant shall have been so exercised; and, unless this Warrant has expired, a new Warrant representing the number of Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder hereof within such time. The person in whose name any certificate for shares of Common Stock is issued upon exercise of this Warrant shall for all purposes be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was received by the Company, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and payment is on a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such Shares at the close of business on the next succeeding date on which the stock transfer books are open.

1.6 RESTRICTIVE LEGEND. Each certificate for Shares shall bear a restrictive legend in substantially the form as follows, together with any additional legend required by (i) any applicable state securities laws and (ii) any securities exchange upon which such Shares may, at the time of such exercise, be listed:

THE SHARES OF STOCK EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ("TRANSFERRED") IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. IN THE ABSENCE OF SUCH REGISTRATION, SUCH SHARES MAY NOT BE TRANSFERRED UNLESS, IF THE COMPANY REQUESTS, THE COMPANY HAS RECEIVED A WRITTEN OPINION FROM COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY STATING THAT SUCH TRANSFER IS BEING MADE IN COMPLIANCE WITH ALL APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

Any certificate issued at any time in exchange or substitution for any certificate bearing such legend shall also bear such legend unless, in the opinion of counsel for the Holder thereof (which counsel shall be reasonably satisfactory to the Company), the securities represented thereby are not, at such time, required by law to bear such legend.

1.7 FRACTIONAL SHARES. No fractional Shares shall be issuable upon exercise or conversion of the Warrant. In the event of a fractional interest, the number of Shares to be issued shall be rounded up to the nearest whole Share.

2. REPRESENTATIONS, WARRANTIES AND COVENANTS.

EXHIBIT 10.95

CERTIFICATE OF DESIGNATIONS OF PREFERENCES AND RIGHTS OF
SERIES A CONVERTIBLE PREFERRED STOCK
OF
INVISA, INC.
a Nevada corporation

The undersigned, Herb Lustig, certifies that:

1. He is the duly acting President of Invisa, Inc., a corporation organized and existing under the Corporation Code of the State of Nevada (the "CORPORATION").

2. Pursuant to authority conferred upon the Board of Directors by the Certificate of Incorporation of the Corporation, and pursuant to the provisions of the Corporations Code of the State of Nevada, said Board of Directors, pursuant to a meeting held August 16, 2004, adopted a resolution establishing the rights, preferences, privileges and restrictions of, and the number of shares comprising, the Corporation's Series A Convertible Preferred Stock, which resolution is as follows:

RESOLVED, that a series of Preferred Stock in the Corporation, having the rights, preferences, privileges and restrictions, and the number of shares constituting such series and the designation of such series, set forth below be, and it hereby is, authorized by the Board of Directors of the Corporation pursuant to authority given by the Corporation's Certificate of Incorporation.

NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors hereby fixes and determines the Determinations of, the number of shares constituting, and the rights, preferences, privileges and restrictions relating to, a new series of Preferred Stock as follows:

(a) Determination. The series of Preferred Stock is hereby designated Series A Convertible Preferred Stock (the "SERIES A PREFERRED STOCK").

(b) Authorized Shares. The number of authorized shares constituting the Series A Preferred Stock shall be Twenty-Two Thousand (22,000) shares of such series.

(c) Dividends. The holder of the Series A Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors, out of any assets of the Corporation legally available therefor, such dividends as may be declared from time to time by the Board of Directors. Nothing herein shall obligate or require the Board of Directors to declare a dividend for the Series A Preferred Stock.

(d) Liquidation Preference.

(i) Preference upon Liquidation, Dissolution or Winding Up. In the event of any dissolution or winding up of the Corporation, whether voluntary or involuntary, holders of each outstanding share of Series A Preferred Stock shall be entitled to be paid first out of the assets of the Corporation available for distribution to shareholders, whether such assets are capital, surplus or earnings, an amount equal to $100.00 (the "SERIES A PURCHASE PRICE") per share of Series A Preferred Stock held (as adjusted for any stock splits,

stock dividends or recapitalizations of the Series A Preferred Stock) and any declared but unpaid dividends on such share, before any payment shall be made to the holders of the Common Stock, or any other stock of the Corporation ranking junior to the Series A Preferred Stock with regard to any distribution of assets upon liquidation, dissolution or winding up of the Corporation. The holders of the Series A Preferred Stock shall be entitled to share ratably, in accordance with the respective preferential amounts payable on such stock, in any distribution which is not sufficient to pay in full the aggregate of the amounts payable thereon. If, upon any liquidation, dissolution or winding up of the Corporation, the assets to be distributed to the holders of the Series A Preferred Stock shall be insufficient to permit payment to such shareholders of the full preferential amounts aforesaid, then all of the assets of the Corporation available for distribution to shareholders shall be distributed to the holders of Series A Preferred Stock. Each holder of the Series A Preferred Stock shall be entitled to receive that portion of the assets available for distribution as the number of outstanding shares of Series A Preferred Stock held by such holder bears to the total number of shares of Series A Preferred Stock. Such payment shall constitute payment in full to the holders of the Series A Preferred Stock upon the liquidation, dissolution or winding up of the Corporation. After such payment shall have been made in full, or funds necessary for such payment shall have been set aside by the Corporation in trust for the account of the holders of Series A Preferred Stock, so as to be available for such payment, such holders of Series A Preferred Stock shall be entitled to no further participation in the distribution of the assets of the Corporation.

(ii) Consolidation, Merger and Other Corporate Events. A consolidation or merger of the Corporation (except into or with a subsidiary corporation) or a sale, lease, mortgage, pledge, exchange, transfer or other disposition of all or substantially all of the assets of the Corporation or any reclassification of the stock of the Corporation (other than a change in par value or from no par to par, or from par to no par or as the result of an event described in subsection (iv), (v), (vi) or (viii) of paragraph (f)), shall be regarded as a liquidation, dissolution or winding up of the affairs of the Corporation within the meaning of this paragraph (d), provided, however, in the case of a merger, if (a) the Corporation is the surviving entity, (b) the Corporation's shareholders hold a majority of the shares of the surviving entity, and (c) the Corporation's directors hold a majority of the seats on the board of directors of the surviving entity, then such merger shall not be regarded as a liquidation, dissolution or winding up within the meaning of this paragraph (d). In no event shall the issuance of new classes of stock, whether senior, junior or on a parity with the Series A Preferred Stock, or any stock splits, be deemed a "reclassification" under or otherwise limited by the terms hereof.

(iii) Distribution of Cash and Other Assets. In the event of a liquidation, dissolution or winding up of the Corporation resulting in the availability of assets other than cash for distribution to the holders of the Series A Preferred Stock, the holders of the Series A Preferred Stock shall be entitled to a distribution of cash and/or assets equal to the value of the liquidation preference stated in subsection (i) of this paragraph (d), which valuation shall be made solely by the Board of Directors, and provided that such Board of Directors was acting in good faith, shall be conclusive.

(iv) Distribution to Junior Security Holders. After the payment or distribution to the holders of the Series A Preferred Stock of the full preferential amounts aforesaid, the holders of Series A Preferred Stock shall have no further rights in respect at such Series A Stock which shall

become null and void, and the holders of the Common Stock then outstanding, or any other stock of the Corporation ranking as to assets upon liquidation, dissolution or winding up of the Corporation junior to the Series A Preferred Stock, shall be entitled to receive ratably all of the remaining assets of the Corporation.

(v) Preference; Priority. References to a stock that is "SENIOR" to, on a "PARITY" with or "JUNIOR" to other stock as to liquidation shall refer, respectively, to rights of priority of one series or class of stock over another in the distribution of assets on any liquidation, dissolution or winding up of the Corporation. The Series A Preferred Stock shall be senior to the Common Stock of the Corporation and senior to any subsequent series of Preferred Stock issued by the Corporation.

(e) Voting Rights. Except as otherwise required by law, the holder of shares of Series A Preferred Stock shall not have the right to vote on matters that come before the shareholders.

(f) Conversion Rights. The holders of Series A Preferred Stock will have the following conversion rights:

(i) Right to Convert. Subject to and in compliance with the provisions of this paragraph (f), any issued and outstanding shares of Series A Preferred Stock may, at the option of the holder, be converted at any time or from time to time into fully paid and non-assessable shares of Common Stock at the conversion rate in effect at the time of conversion, determined as provided herein; provided, that a holder of Series A Preferred Stock may at any given time convert only up to that number of shares of Series A Preferred Stock so that, upon conversion, the aggregate beneficial ownership of the Corporation's Common Stock (calculated pursuant to Rule 13d-3 of the Securities Exchange Act of 1934, as amended) of such holder and all persons affiliated with such holder is not more than 9.99% of the Corporation's Common Stock then outstanding.

(ii) Mechanics of Conversion. Before any holder of Series A Preferred Stock shall be entitled to convert the same into shares of Common Stock, he shall surrender the certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Common Stock, and shall give written notice to the Corporation at such office that he elects to convert the same and shall state therein the number of shares of Series A Preferred Stock being converted. Thereupon, the Corporation shall promptly issue and deliver at such office to such holder of Series A Preferred Stock a certificate or certificates for the number of shares of Common Stock to which he shall be entitled. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Series A Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date.

(iii) Conversion Price. The number of shares into which one share of Series A Preferred Stock shall be convertible shall be determined by dividing the Series A Purchase Price by the then existing Conversion Price (as set forth below) (the "CONVERSION RATIO"). The "CONVERSION PRICE" per share for the Series A Preferred Stock shall be equal to Eighty percent (80%) of the Market Price (as defined below and subject to adjustment as described below),

rounded to the nearest penny; provided, however, that subject to the provisions of the next sentence, in no event shall the Conversion Price be less than $0.50 per share (the "FLOOR PRICE") or exceed $1.17 (the "CEILING PRICE"). The Floor Price and Ceiling Price shall be further adjusted upon the occurrence of any event in paragraph (f) (iv)-(vi).

"MARKET PRICE" on any given date shall be the volume weighted average price of the Corporation's Common Stock for the 10 immediately preceding trading days, provided, that such 10 trading day period shall be extended by the number of trading days during such period on which (i) trading in the Corporation's Common Stock is suspended by, or not traded on, the OTC Bulletin Board or a subsequent market on which the common stock is then traded, or (ii) after the date of Registration Statement (the "Registration Statement") for the underlying shares of common stock of the Corporation into which the Series A Preferred Stock may be converted is declared effective by the SEC, the prospectus included in the Registration Statement may not be used by the holder for resale of underlying shares of common stock, is suspended by, or not traded on, the OTC Bulletin Board or a subsequent market on which the common stock is then listed, or (iii) after the date the Registration Statement is declared effective by the SEC, the prospectus included in the Registration Statement for the underlying shares may not be used by the holder for the resale of underlying shares of common stock (provided such inability to use the prospectus is not (a) caused by the holder or (b) as a result of the Company's filing of post-effective amendments to the Registration Statement.)

For purposes of illustration only, assuming the Ceiling Price is $1.30 per share, if the Market Price is $1.35 at time of a conversion, the Conversion Ratio will be $100.00/$1.08, allowing the 22,000 shares of Series A Preferred Stock to be converted into 2,037,037 shares of Common Stock. On the other hand, if the Market Price is $1.75 at time of a conversion, the Conversion Ratio will be $100.00/$1.30, allowing the 22,000 shares of Preferred Stock to be converted into 1,692,308 shares of Common Stock.

If an Event of Default occurs, as defined in the Subscription Agreement for the Series A Preferred Stock, the Conversion Price shall be reduced to Seventy percent (70%) of the Market Price, provided, however, in no event shall the Conversion Price be less than the Floor Price.

(iv) Adjustment for Stock Splits and Combinations. If the Corporation shall at any time, or from time to time after the date shares of the Series A Preferred Stock are first issued (the "ORIGINAL ISSUE DATE"), effect a subdivision of the outstanding Common Stock, the Floor Price and Ceiling Price in effect immediately prior thereto shall be proportionately decreased, and conversely, if the Corporation shall at any time or from time to time after the Original Issue Date combine the outstanding shares of Common Stock, the Floor Price and Ceiling Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph (f)(iv) shall become effective at the close of business on the date the subdivision or combination becomes effective.

(v) Adjustment for Certain Dividends and Distributions. In the event the Corporation at any time, or from time to time after the Original Issue Date, shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in

additional shares of Common Stock, then and in each such event the Floor Price and Ceiling Price then in effect shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Floor Price and Ceiling Price then in effect by a fraction:

(A) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and

(B) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution; provided, however, if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Floor Price and Ceiling Price shall be recomputed accordingly as of the close of business on such record date and thereafter, the Floor Price and Ceiling Price shall be adjusted pursuant to this paragraph
(f)(v) as of the time of actual payment of such dividends or distributions.

(vi) Adjustments for Other Dividends and Distributions. In the event the Corporation at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation other than shares of Common Stock, then and in each such event provision shall be made so that the holders of such Series A Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the amount of securities of the Corporation that they would have received had their Series A Preferred Stock been converted into Common Stock on the date of such event and had thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by them as aforesaid during such period giving application to all adjustments called for during such period under this paragraph (f) with respect to the rights of the holders of the Series A Preferred Stock.

(vii) Adjustment for Reclassification Exchange or Substitution. If the Common Stock issuable upon the conversion of the Series A Preferred Stock shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares or stock dividend provided for above, or a reorganization, merger, consolidation or sale of assets provided for elsewhere in this paragraph (f)), then and in each such event the holder of each share of Series A Preferred Stock shall have the right thereafter to convert such share into the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification or other change, by holders of the number of shares of Common Stock into which such shares of Series A Preferred Stock might have been converted immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein.

(viii) Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there shall be a capital reorganization of the Common Stock (other than a subdivision, combination, reclassification or exchange of shares provided for elsewhere in this paragraph

(f)) or a merger or consolidation of the Corporation with or into another corporation, or the sale of all or substantially all of the Corporation's properties and assets to any other person, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the holders of the Series A Preferred Stock shall thereafter be entitled to receive upon conversion of such Series A Preferred Stock, the number of shares of stock or other securities or property of the Corporation or of the successor corporation resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital reorganization, merger, consolidation or sale. In any such case, appropriate adjustment shall be made in the application of the provisions of this paragraph (f) with respect to the rights of the holders of the Series A Preferred Stock after the reorganization, merger, consolidation or sale to the end that the provisions of this paragraph (f) (including adjustment of the Floor Price and Ceiling Price then in effect and the number of shares purchasable upon conversion of the Series A Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable.

(ix) Sale of Common Stock or Securities Convertible Into Common Stock. In the event the Corporation sells or issues Common Stock or other securities convertible into or exercisable for Common Stock at a per share price, exercise price or conversion price lower than the Conversion Price then in effect (other than in connection with an acquisition of the securities, assets or business of another company, licensing, partnership, technology transfer, marketing alliance, joint ventures or employee, director, officer, or consultant issuances or stock options), the Conversion Price shall be subject to weighted average anti-dilution adjustments.

(x) Certificate of Adjustment. In each case of an adjustment or readjustment of the Floor Price and Ceiling Price or the securities issuable upon conversion of the Series A Preferred Stock, the Corporation shall compute such adjustment or readjustment in accordance herewith and the Corporation's Chief Financial Officer shall prepare and sign a certificate showing such adjustment or readjustment, and shall mail such certificate by first class mail, postage prepaid, to each registered holder of the Series A Preferred Stock at the holder's address as shown in the Corporation's books. The certificate shall set forth such adjustment or readjustment, showing in detail the facts upon which such adjustment or readjustment is based.

(xi) Notices of Record Date. In the event of (A) any taking by the Corporation of a record of the holders of any class or series of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution or (B) any reclassification or recapitalization of the capital stock of the Corporation, any merger or consolidation of the Corporation or any transfer of all or substantially all of the assets of the Corporation to any other corporation, entity or person, or any voluntary or involuntary dissolution, liquidation or winding up of the Corporation, the Corporation shall mail to each holder of Series A Preferred Stock at least 10 days prior to the record date specified therein, a notice specifying (1) the date on which any such record is to be taken for the purpose of such dividend or distribution and a description of such dividend or distribution, (2) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up is expected to become effective and (3) the time, if any is to be fixed, as to when the holders of record of Common Stock (or other securities) shall be entitled to exchange their shares, of Common Stock (or other securities) for securities or

other property deliverable upon such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up.

(xii) Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Series A Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall round the shares up to the nearest whole number.

(xiii) Reservation of Stock Issuable Upon Conversion. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series A Preferred Stock, Four Million Four Hundred Thousand (4,400,000) shares of Common Stock, and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of Series A Preferred Stock, the Corporation will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose.

(xiv) Notices. Any notice required by the provisions of this paragraph (f) to be given to the holders of shares of Series A Preferred Stock shall be deemed given (A) if deposited in the United States mail, postage prepaid, or (B) if given by any other reliable or generally accepted means (including by facsimile or by a nationally recognized overnight courier service), in each case addressed to each holder of record at his address (or facsimile number) appearing on the books of the Corporation.

(xv) Payment of Taxes. The Corporation will pay all transfer taxes and other governmental charges that may be imposed in respect of the issue or delivery of shares of Common Stock upon conversion of shares of Series A Preferred Stock.

(xvi) No Dilution or Impairment. The Corporation shall not amend its Articles of Incorporation or participate in any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, for the purpose of avoiding or seeking to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, without the approval of a majority of the then outstanding Series A Preferred Stock.

(g) No Re-issuance of Preferred Stock. Any shares of Series A Preferred Stock acquired by the Corporation by reason of purchase, conversion or otherwise shall be canceled, retired and eliminated from the shares of Series A Preferred Stock that the Corporation shall be authorized to issue. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock subject to the conditions and restrictions on issuance set forth in the Articles of Incorporation or in any certificate of designation creating a series of Preferred Stock or any similar stock or as otherwise required by law.

(h) Severability. If any right, preference or limitation of the Series A Preferred Stock set forth herein is invalid, unlawful or incapable of being enforced by reason of any rule, law or public policy, all other rights, preferences and limitations set forth herein that can be given effect without

the invalid, unlawful or unenforceable right, preference or limitation shall nevertheless remain in full force and effect, and no right, preference or limitation herein shall be deemed dependent upon any other such right, preference or limitation unless so expressed herein.

3. The number of authorized shares of Preferred Stock of the Corporation is 5,000,000 and the number of shares of Series A Stock, none of which has been issued, is 22,000.

Each of the undersigned declares under penalty of perjury that the matters set out in the foregoing Certificate are true of his own knowledge. Executed at Sarasota, Florida, on this 16th, day of August, 2004.
